The tubular body 91 is formed of a material harder than the elastic portion 91a on the base end side, and has a connecting portion 91b that can be connected to the main body portion 10. The tubular body 91 is formed by integrally molding two different members of the elastic portion 91a and the connecting portion 91b. The elastic portion 91a is made of a material that is elastically deformable (flexible and deformable) such as an elastomer. By attaching such an airtightness holding member 90 to the connection port 10a of the vacuum cleaner main body 1, the entire tip 90s of the airtightness holding member 90 can be brought into close contact with the floor surface, and the suction force is improved as compared with the case where the airtightness holding member 90 is not brought into close contact. Can be made to. Further, by forming the connecting portion 91b with a hard one, the airtightness holding member 90 can be attached to the main body portion 10 in a stable state without falling off.

In the present embodiment, the case where the elastic portion 91a is formed of an elastic material such as an elastomer has been described as an example, but the present invention is not limited to this. For example, substantially the entire tubular body 91 may be formed of the same material as the connecting portion 91b, and short hairs electrostatically transplanted at the tip of the tubular body 91 may be provided in an annular shape. Even with such an electrostatic flocking, the tip of the airtightness holding member 90 can be brought into close contact with the floor surface as in the elastomer, and the suction force can be improved.

A vertically elongated fitting groove 10b is formed on the outer surface of the connection port 10a of the main body 10. One fitting groove 10b is formed on each of the left and right sides. At the base end of the connecting portion 91b, a protrusion (not shown) is formed which is concavely fitted and locked with the fitting groove 10b.

Further, the main body 10 is provided with a light emitting element 10c (see FIG. 2) above the connection port 10a. The light emitting element 10c is configured to emit light toward the front, that is, the surface to be cleaned (floor surface or the like). Further, the tip surface 10c1 of the light emitting element 10c is located on substantially the same surface as the tip 10a1 of the connection port 10a.

The storage battery 3 supplies electric power to an electric blower 40 (see FIG. 6) and the like, and is composed of a secondary battery such as lithium ion and nickel hydrogen. Further, the storage battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and can be attached to and detached from the main body 10 by sliding the case 3a in the front-rear direction.

A terminal portion 3b connected to the main body portion 10 is provided on the upper surface of the case 3a. Further, on the upper surface of the case 3a, a slide groove 3c that is slidably supported by the main body 10 is formed in front of the terminal portion 3b. Further, on the upper surface of the case 3a, behind the terminal portion 3b, slide rails 3d and 3d slidably supported by the main body portion 10 are formed so as to project to the left and right sides.

Further, on the front surface of the case 3a, an introduction hole 3e into which cooling air for cooling the storage battery 3 is introduced is formed on one side (left side) in the left-right direction (width direction). The introduction hole 3e is formed elongated in the vertical direction.

Further, on the front surface of the case 3a, a discharge hole 3f is formed on the other side (right side) in the left-right direction (width direction) to discharge the air after cooling the storage battery 3. The discharge hole 3f is formed so as to have a symmetrical shape with the introduction hole 3e described above.

Further, on the back surface of the case 3a, a lock recess 3g is formed in which the lock member 13 is fitted and locked to the main body 10.

FIG. 3 is an arrow view in the X direction of FIG.
As shown in FIG. 3, the dust case 2 is of a cyclone type, and has a function of separating air including dust sucked from the introduction pipe 14 into dust and air and collecting the dust. Further, the dust case 2 is arranged in front of the motor case portion 11 with the axial direction in the front-rear direction, and has a substantially cylindrical accommodating portion 2a. Further, a substantially rectangular inflow port 2b (see FIG. 2) connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust case 2. The air containing dust that has flowed into the inflow port 2b becomes a swirling flow, centrifugal force acts on the dust, and after being separated into dust and air in the dust case 2, the air from which the dust is separated is the dust case. It is discharged from the rear part (back side) of 2.

Further, on the front surface of the dust case 2, a lid 2c that opens and closes when the dust accumulated in the dust case 2 is discarded is rotatably supported via a hinge portion 2d. Further, a lid lock mechanism 2e for unlocking the lid 2c is provided on the upper portion of the lid 2c. The internal mechanism of the dust case 2 can be configured based on JP-A-2016-137165.

An exhaust port 16 is provided at the lower part of the motor case portion 11. The exhaust port 16 has a plurality of slits 16a along the front-rear direction, and the plurality of slits 16a are formed side by side in the vertical direction. Although not shown, the exhaust ports 16 are provided on both the left and right sides.

FIG. 4 is a perspective view of the vacuum cleaner of the present embodiment.
As shown in FIG. 4, in the vacuum cleaner 100, the dust case 2 is attached below the main body 10 and in front of the motor case 11. In this case, when the dust case 2 is attached to the vacuum cleaner main body 1, the lid lock mechanism 2e is hidden on the vacuum cleaner main body 1 side. This is because if the lid lock mechanism 2e is provided on the opposite side (outside), the lid lock mechanism 2e may be released during cleaning, but the lid lock mechanism 2e is hidden behind the vacuum cleaner body 1. This is because malfunction can be prevented. For example, when cleaning under a sofa or a bed in a stick state, the vacuum cleaner main body 1 may be brought closer to the floor surface horizontally. At this time, if the lid lock mechanism 2e is provided on the front side, the lid lock mechanism 2e may be released in contact with the floor surface. The positions of the lid lock mechanism 2e and the hinge portion 2d are not limited to this, and may be provided on the left and right sides of the vacuum cleaner main body 1.

Further, the dust case 2 is provided with a cleaning brush 2s (see FIGS. 2 and 3) in a detachable manner. The care brush 2s is arranged at a position where it is difficult to see from the outside when the dust case 2 is attached to the vacuum cleaner main body 1. Therefore, it is difficult to remove the cleaning brush 2s during operation, and it is not necessary to store the cleaning brush 2s in a place different from the vacuum cleaner 100.

Further, when the airtightness holding member 90 is attached to the vacuum cleaner main body 1, the light emitting element 10c is covered by the airtightness holding member 90. In other words, in the airtightness holding member 90, the inner diameter of the airtightness holding member 90 is set so that the light emitting element 10c is located inside the airtightness holding member 9.

FIG. 5 is a plan view of the vacuum cleaner of the present embodiment.
As shown in FIG. 5, the connecting portions 91b of the airtightness holding member 90 are formed with extending portions 91b1 and 91b1 extending rearward on both the left and right sides. A concave portion 91b2 is formed between the extension portion 91b1 on the left side and the extension portion 91b1 on the right side in a plan view. The concave portion 91b2 fits with the front end portion 10d1 of the protruding portion 10d formed on the upper surface of the tip of the main body portion 10. As a result, the airtightness holding member 90 is positioned in the front-rear direction and the left-right direction with respect to the connection port 10a (see FIG. 2).

The introduction pipe 14 formed in the main body 10 is formed so as to extend diagonally rearward to the right and then downward, and is connected to the inflow port 2b (see FIG. 2) of the dust case 2. As a result, a swirling flow can be generated in the accommodating portion 2a of the dust case 2, and dust can be effectively separated by centrifugal force.

The width of each of the dust case 2 and the storage battery 3 is formed to be slightly shorter than the width W of the main body 10. In other words, the dust case 2 and the storage battery 3 are configured so as not to protrude from the side of the main body 10. As a result, the vacuum cleaner 100 can be smoothly moved in the front-rear direction regardless of whether the user holds it with either the left or right hand for cleaning, and the usability can be improved.

FIG. 6 is a sectional view taken along line VI-VI of FIG. Note that FIG. 6 shows a state in which the airtightness holding member 90 is removed from the vacuum cleaner 100.
As shown in FIG. 6, the electric blower 40 is housed in the motor case portion 11 of the main body portion 10. Further, in the motor case portion 11, a main body board 50 (control board) for controlling the vacuum cleaner main body 1 is housed below the electric blower 40.

The electric blower 40 is arranged horizontally so that the rotary drive shaft 40a faces the front-rear direction (horizontal direction). Further, the air discharged from the electric blower 40 flows to the main body substrate 50 arranged below the electric blower 40 to cool the main body substrate 50. Further, a part of the air that has cooled the main body substrate 50 is designed to cool the storage battery 3.

The main board 50 has an upper board 50a and a lower board 50b which are divided into upper and lower parts and arranged in two stages, and various parts are mainly placed on opposite surfaces (lower surface of the upper board 50a and upper surface of the lower board 50b). It is implemented. Most of the air discharged from the electric blower 40 flows so as to cool the parts (heat generating parts) arranged opposite to each other of the main body substrate 50. Further, the main body substrate 50 is covered with a flame-retardant resin case 51, and the wind (air) discharged from the electric blower 40 flows in the resin case 51 from the rear side to the front side, and the resin. It flows to the storage battery 3 side through the lower side of the bottom surface of the case 51.

Further, the electric blower 40 and the main body substrate 50 are arranged so as to overlap each other in the vertical direction. Therefore, the dimensions in the front-rear direction can be shortened. Further, in the electric blower 40, the motor case portion 11 is formed so as to bulge toward the handle portion 12, so that the dimension of the main body portion 10 in the front-rear direction (total length) can be shortened.

Further, the electric blower 40 and the main body substrate 50 are located below the first grip portion 12a1 of the handle portion 12. As a result, when the user grips and operates the grip portion 12a1, the center of gravity of the vacuum cleaner 100 is near the lower side of the first grip portion 12a1. Therefore, when the tip of the vacuum cleaner 100 is used upward, the electric cleaning is performed. The machine 100 can be held stably.

Further, a gap 12c having a width dimension H1 for inserting a hand is formed between the first grip portion 12a1 and the upper surface 11c of the motor case portion 11. Further, a gap 12d having a width dimension H2 wider than the width dimension H1 is formed between the second grip portion 12a2 and the back surface 11d of the motor case portion 11. In this way, when the first grip portion 12a1 is gripped and cleaned, the arm can be held in an extended state, so that the vacuum cleaner 100 can be moved back and forth without firmly gripping the first grip portion 12a1. it can. Further, when the second grip portion 12a2 is gripped and cleaned, it is necessary to insert a hand (finger) deeply into the gap 12d and grip it strongly. Therefore, by making the width dimension H2 wider than the width dimension H1. The second grip portion 12a2 can be gripped stably.

Further, the thickness T1 of the first grip portion 12a1 is formed to be thin, and the thickness T2 of the second grip portion 12a2 is formed to be thicker than the thickness T1. That is, the first grip portion 12a1 is formed to be thin, and the second grip portion 12a2 is formed to be thick. In this way, when the second grip portion 12a2 is gripped and cleaned, the thickness T2 of the second grip portion 12a2 can be increased to facilitate deep grip and increase the strength of the second grip portion 12a2. it can.

The storage battery 3 can be composed of, for example, a lithium ion battery having high energy efficiency. Further, the storage battery 3 is arranged below the second grip portion 12a2 of the handle portion 12. By providing the storage battery 3 at the rear end of the vacuum cleaner 100 in this way, the center of gravity of the handle portion 12 becomes closer to the second grip portion 12a2, so that when the tip of the vacuum cleaner 100 is used upward, the operation feeling is felt. Can be lightened.

The lock member 13 has a button-shaped operation portion 13a formed at the rear end portion. The operating portion 13a has an arm portion 13b extending forward, and the front end of the arm portion 13b is supported by the main body portion 10. Further, the arm portion 13b is urged downward by the spring 13c. As a result, when the lock member 13 is fitted into the lock recess 3g and locked, the operating portion 13a is prevented from coming out of the lock recess 3g. Further, when the storage battery 3 is removed from the main body 10, the operation portion 13a can be pulled out from the lock recess 3g while repelling the urging force of the spring 13 by pressing the operation portion 13a.

By making the storage battery 3 removable in this way, it becomes easier to replace the storage battery 3 as compared with a non-detachable storage battery. In addition, by preparing a spare storage battery 3 and a charging box capable of charging the spare storage battery 3 as an option, when the storage battery on the main body side of the vacuum cleaner 100 is exhausted, it can be replaced with the spare storage battery 3. It is possible to extend the cleaning time. With such a configuration, it is effective when cleaning a wide floor surface such as a store, for example.

As shown in FIG. 6, when the surface passing through the tip surface of the connection port 10a of the main body 10 is R1, the tip 2f of the dust case 2 and the surface R1 (the surface extending in the vertical direction with respect to the paper surface) are approximately abbreviated. It is configured to be flush. The tip 2f of the dust case 2 does not protrude forward from the surface R1. As a result, even when cleaning the vacuum cleaner body 1 without attaching the airtightness holding member 90, the tip of the connection port 10a can be cleaned while being in contact with a hard floor surface such as flooring.

In the dust case 2, the filter 5 is housed at the rear end of the housing portion 2a in the axial direction. The filter 5 is formed by folding it into a pleated shape, so that the filter area can be increased and the pressure loss due to the filter 5 can be reduced.

Further, the filter 5 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The HEPA filter is an air filter having a particle collection rate of 99.97% or more and an initial pressure loss of 245 Pa or less with respect to particles having a rated air volume and a particle size of 0.3 μm.

FIG. 7 is a side view of the vacuum cleaner of the present embodiment.
As shown in FIG. 7, the vacuum cleaner 100 has an exhaust port 16 for discharging the sucked air to the outside. The exhaust port 16 is formed at a height position of the main body substrate 50 (see FIG. 6). Further, a louver (air passage switching member) 16b is attached to the outer surface of the exhaust port 16 so as to cover a plurality of slits 16a (see FIG. 3). In FIG. 7, the exhaust port 16 on the front side of the paper is closed by the louver 16b, and the exhaust port on the opposite side is open.

The airtightness holding member 90 is formed so that the tip (tip surface) 90s is inclined so as to retract from the upper part to the lower part. The dust case 2 is located behind the surface R2 passing through the tip 90s. As a result, even when the tip 90s of the airtight holding member 90 is brought into contact with the floor surface such as flooring, it is possible to prevent the dust case 2 from hitting the floor surface.

FIG. 8 is a sectional view taken along line VIII-VIII of FIG.
As shown in FIG. 8, the slit 16a of the exhaust port 16 is formed on the left and right sides of the wall surface 16c having a substantially semicircular shape. A plurality of slits 16a are formed on the left and right sides of the wall surface 16c. The louver 16b is slidably provided along the wall surface 16c. Further, the louver 16b is formed with ridge portions 16b1 and 16b1 at both ends in the circumferential direction. In FIG. 8, the louver 16b is located on the left side (right side in the drawing), and the slit 16a on the right side (left side in the drawing) is exposed.

The main body substrate 50 is housed in a case 51 made of flame-retardant resin, in which an upper substrate 50a and a lower substrate 50b are vertically separated from each other and formed in a concave shape. The case 51 has a bottom surface portion 51a and left and right side surface portions 51b and 51c. Therefore, the upper substrate 50a and the lower substrate 50b cannot be visually recognized from the outside through the slit 16a of the exhaust port 16. As a result, in the vacuum cleaner 100, it is possible to prevent foreign matter from entering from the outside of the exhaust port 16 and coming into contact with the main body substrate 50.

Further, the exhaust port 16 is formed so as to communicate with the motor case portion 11 so that the exhaust gas from the electric blower 40 is discharged from the slit 16a after cooling the main body substrate 50. Further, since the exhaust port 16 is located at the lower part of the motor case portion 11, it is possible to suppress the exhaust from hitting the user. Further, since the exhaust port 16 of the present embodiment can freely change the left-right direction of the exhaust, it is possible to prevent the exhaust from directly hitting the user regardless of whether the user is right-handed or left-handed.

Further, on the surface of the louver 16b, ridges 16b1 and 16b1 protruding outward are formed. As a result, when the louver 16b is moved left and right, it becomes easy to hook a finger on the ridge portion 16b1, so that the operation of moving the louver 16b left and right becomes easy, and the direction of the exhaust can be changed quickly and easily. be able to.

FIG. 9 is a sectional view taken along line XI-XI of FIG.
As shown in FIG. 9, in the storage battery 3, six cell cells 3h (battery cells) are arranged side by side in the case 3a, three on the top and three on the bottom. Further, in the upper three cell cells 3h1, the cell cells 3h1 in the center of the left and right are arranged at positions lower than the cell cells 3h1 on both the left and right sides, and the center of the cell cells 3h1 when the cell cells 3h1 are viewed from the axial direction. The lines connecting the above are arranged so as to be V-shaped. Further, the lower three cell batteries 3h2 are also arranged in a V shape in the same manner. In this way, by directing the axial direction of the cell 3h (3h1, 3h2) in the front-rear direction, the width of the storage battery 3 can be narrowed as compared with the case where the axial direction of the cell 3h is directed in the left-right direction. Further, the width of the storage battery 3 can be further narrowed by arranging the cell cells 3h1 and 3h2 in two upper and lower stages and arranging the cell cells 3h1 and 3h2 in a V shape. By narrowing the left and right widths in this way, it is possible to reduce the contact of the storage battery 3 with the user during cleaning.

By arranging the cell cells 3h in a V shape in this way, a recessed portion 3i is formed on the upper side of the case 3a. The case 3a is formed with the slide groove 3c so as to project toward the recessed portion 3i. On the other hand, a rail portion 15 having a T-shape in cross section that slidably supports the slide groove 3c is formed in the main body portion 10 (below the handle portion 12) facing the slide groove 3c. By forming the slide groove 3c in the dead space in this way, the space can be effectively used and the height dimension of the storage battery 3 can be kept low.

Further, the cell 3h is housed in the case 3a in a state of being held by the holding member 3j made of synthetic resin. The holding member 3j is configured such that gaps 3k1 and 3k1 are formed between the upper cell 3h1 and the lower cell 3h2. Further, a gap 3k2 is formed between the upper surface of the holding member 3j and the upper surface of the case 3a. Further, gaps 3k3 and 3k3 are formed between the left and right side surfaces of the holding member 3j and the side surfaces of the case 3a. Further, gaps 3k4 and 3k4 are formed between the lower surface of the holding member 3j and the lower surface of the case 3a.

By forming such a gap 3k1, 3k2, 3k3, 3k4, air can flow around each cell 3h, and each cell 3h (3h1,3h2) can be effectively cooled.

FIG. 10 is a perspective view showing a state in which the battery is removed from the vacuum cleaner of the present embodiment as viewed from diagonally rearward on the back surface.
As shown in FIG. 10, air that has cooled the main body substrate 50 (see FIG. 8) is led out from the main body 10 (vacuum cleaner main body 1) on the back surface of the motor case 11 (the surface facing the front surface of the storage battery 3). The lead-out hole 11s to be (discharged) is formed. The lead-out hole 11s is formed at a position facing the introduction hole 3e (see FIG. 2) of the storage battery 3. In other words, when the storage battery 3 is mounted on the main body 10, the lead-out hole 11s and the introduction hole 3e are configured to communicate with each other. Further, the communication direction between the lead-out hole 11s and the introduction hole 3e is the front-rear direction.

The main body portion 10 is formed with hanging portions 10e and 10e hanging from both left and right ends below the handle portion 12. On the inner wall surface of the hanging portion 10e, a protruding portion 10f protruding inward is formed so as to extend in the front-rear direction. The protrusion on the left side is not shown. As a result, the storage battery 3 is supported by the main body 10 by sliding the slide rails 3d and 3d on the protrusion 10f with the storage battery 3 facing forward from the back side (rear) of the vacuum cleaner main body 1. Then, when the back surface portion 3 m of the case 3a of the storage battery 3 abuts on the rear end surface of the hanging portion 10e, the storage battery 3 is locked to the main body portion 10 by the lock member 13. At this time, the lead-out hole 11s of the main body 10 and the introduction hole 3e (see FIG. 2) of the storage battery 3 are in a communicating state, and the air led out from the lead-out hole 11s is introduced into the introduction hole 3e (see FIG. 2). ..

FIG. 11 is a perspective view showing a state in which the vacuum cleaner of the present embodiment is looked up from below.
As shown in FIG. 11, a holding plate 11t for holding the louver 16b is formed at the lower end of the motor case portion 11. The movement of the louver 16b in the right direction is restricted by the contact of the left ridge portion 16b1 with the left edge portion of the holding plate 11t. Similarly, the movement of the louver 16b in the left direction is restricted by the contact of the right ridge portion 16b1 (see FIG. 8) with the right edge portion of the holding plate 11t. By holding the louver 16b by the holding plate 11t in this way, it is possible to prevent the louver 16b from falling off from the motor case portion 11. Further, by holding the louver 16b by the holding plate 11t, the louver 16b, which is a movable member, does not come into contact with the floor surface or the like, and the louver 16b can be prevented from being damaged.

Further, on the lower surface of the motor case portion 11, a support portion 11p having a flat surface 11p1 is formed in front of the exhaust port 16. On the other hand, a support portion 3p having a rectangular flat surface 3p1 is formed on the lower surface of the storage battery 3. The plane 11p1 and the plane 3p1 are located on the same plane. As a result, when the vacuum cleaner main body 1 is placed on the floor surface or the like in a handy state, the support portions 3p and 11p support the connection port 10a in a horizontal direction parallel to the floor surface.

FIG. 12 is a front view of the vacuum cleaner of the present embodiment.
As shown in FIG. 12, the main body 10 is provided with an airtight holding member 90 so as to surround the connection port 10a. The airtight holding member 90 has an opening 90t having a diameter larger than the diameter D of the connection port 10a. The opening 90t has a length in the vertical direction longer than the length in the horizontal direction, and has a substantially elliptical shape when viewed from the axial direction.

Further, in the main body 10 (vacuum cleaner main body 1), connection terminals 10u and 10u electrically connected to the various attachments (see FIG. 1, excluding the broom-type suction port 700) are formed above the connection port 10a. Has been done. Then, in the main body 10 (vacuum cleaner main body 1), a light emitting element 10c is formed further above the connection terminals 10u and 10u. That is, the airtightness holding member 90 has not only the connection port 10a but also the openings 90t surrounding the connection terminals 10u and 10u and the light emitting element 10c.

In this way, by making the airtightness holding member 90 larger in diameter than the connection port 10a and attaching it to the outside of the connection port 10a (the outer surface side of the vacuum cleaner main body 1), the airtightness holding member 90 can be attached to the main body 10 (vacuum cleaner). The attachment can be attached and detached without removing it from the main body 1). As a result, when the vacuum cleaner main body 1 is being cleaned in the stick state, the release button 18 can be operated to switch to the handy state. Moreover, in this case, since the airtightness holding member 90 is still connected to the connection port 10a of the vacuum cleaner main body 1, cleaning can be continued with the suction force increased.

Further, in the vacuum cleaner 100, even when the gap / brush switching nozzle 110 (see FIG. 1) is connected to the connection port 10a, the light emitting element 10c is located inside the airtightness holding member 90 and outside the attachment. ing. As a result, the floor surface can be illuminated from between the airtightness holding member 90 and the gap / brush switching nozzle 110, and the cleanability of a dark place such as a gap in furniture can be improved.

FIG. 13A shows an irradiation state by the light emitting element when the airtightness holding member is attached, and FIG. 13B shows an irradiation state by the light emitting element when the airtightness holding member is not attached.
In the comparative example shown in FIG. 13B, the light emitted from the light emitting element 10c is applied to the floor surface M while being diffused from the connection port 10a. Therefore, when the light is diffused in a high range, the light radiated to the floor surface M becomes vague and dark. On the other hand, in the present embodiment shown in FIG. 13A, the light emitted from the light emitting element 10c is suppressed from being diffused by the airtightness holding member 90, and the floor surface is affected by the flashlight effect of the airtightness holding member 90. M is irradiated in a spot. Since the light is focused in this way, the light emitted to the floor surface M is brighter than that in FIG. 13 (b). Therefore, the dust on the floor surface M can be easily discriminated, and the cleanability can be improved.

FIG. 14 is a schematic view showing a cooling structure of the storage battery.
As shown in FIG. 14, when the storage battery 3 is mounted on the vacuum cleaner main body 1, the lead-out hole 11s and the introduction hole 3e communicate with each other in a state of facing each other. At this time, the communication direction between the lead-out hole 11s and the introduction hole 3e is the front-rear direction. When the electric blower 40 (see FIG. 6) is driven in this state, the sucked air flows through the motor case portion 11 toward the outlet hole 11s. Then, the air discharged from the lead-out hole 11s is supplied to the introduction hole 3e and flows from the front to the rear of the cell 3h through the gaps 3k1, 3k3 and the like to cool the cell 3h. Then, the air that has flowed to the rear of the cell 3h flows from the rear to the front of the cell 3h through the gaps 3k1 and 3k3, and flows toward the discharge hole 3f. Then, the air discharged from the discharge hole 3f collides with the back surface of the motor case portion 11 and is discharged to the outside through the gap between the motor case portion 11 and the case 3a of the storage battery 3. The air discharged from the discharge hole 3f may be returned to the inside of the motor case portion 11 and discharged to the outside through the gap on the vacuum cleaner main body 1 side. Further, the storage battery 3 may be provided with a slit so that air can be discharged from the slit.

In the above description, the case where the partition plate for guiding the air flow is not provided inside the storage battery 3 has been described as an example, but the partition for guiding the air to the back side (rear side) in the storage battery 3 has been described. A board may be provided.

Further, in the above description, a part of the air generated by the suction force of the electric blower 40 (see FIG. 6) is discharged from the exhaust port 16 (see FIG. 3) after cooling the main body substrate 50 (see FIG. 6). The case where the remaining part is used for cooling the storage battery 3 has been described as an example. In addition, all the air that cooled the main body substrate 50 may be used for cooling the storage battery 3. As a result, the storage battery 3 can be cooled more efficiently. Further, the air from the electric blower 40 may be divided into the main body substrate 50 and the lead-out hole 11s to cool the storage battery 3. As a result, by cooling with air that does not pass through the main body substrate 50, the storage battery 3 can be cooled with cooler air, and the cooling efficiency of the storage battery 3 can be improved.

Further, in the vacuum cleaner 100, by making the opening area of the introduction hole 3e larger than the opening area of the lead-out hole 11s, the air led out from the lead-out hole 11s can be easily introduced into the introduction hole 3e, and the storage battery 3 can be used. Can be cooled efficiently.

FIG. 15A is a cross-sectional view showing a modified example of the communication structure between the outlet and the introduction port, and FIG. 15B is a cross-sectional view showing another modification of the communication structure between the outlet and the introduction port.
As shown in FIG. 15A, the lead-out hole 11s1 formed in the motor case portion 11 has a convex shape protruding toward the storage battery 3, and the introduction hole 3e1 formed in the storage battery 3 has a concave shape. The structure may be such that the 11s1 and the introduction hole 3e1 are unevenly fitted. The storage battery 3 side may have a convex shape, and the motor case portion 11 side may have a concave shape. As a result, the airtightness between the lead-out hole 11s1 and the introduction hole 3e1 can be improved, and the air led out from the lead-out hole 11s1 can be efficiently introduced into the introduction hole 3e1.

Further, as shown in FIG. 15B, an annular seal member 19 that surrounds both the entire circumference of the lead-out hole 11s and the entire circumference of the introduction hole 3e may be provided between the lead-out hole 11s and the introduction hole 3e. Good. As a result, the airtightness between the lead-out hole 11s and the introduction hole 3e can be improved, and the air led out from the lead-out hole 11s can be efficiently introduced into the introduction hole 3e.

FIG. 16 is a plan view of a state in which accessories are connected to the vacuum cleaner.
As shown in FIG. 16, the vacuum cleaner 100 is configured so that the extension pipe 300 can be connected in a state where the airtightness holding member 90 is connected to the vacuum cleaner main body 1. As described above, even if the airtightness holding member 90 is connected to the vacuum cleaner main body 1, the position of the connection port 10a for connecting the extension pipe 300 does not change. Therefore, the total length L connecting the vacuum cleaner main body 1, the extension pipe 300, and the standard suction port 400 can be kept short. As a result, the position of the standard mouthpiece 400 is closer to the hand, so that the handling is improved and the usability can be improved.

In the vacuum cleaner 100 shown in FIG. 16, even if the extension pipe 300 to which the standard suction port 400 is connected is removed from the stick state to bring it into a handy state, the airtightness holding member 90 remains attached to the vacuum cleaner body 1. .. Therefore, cleaning can be performed with the suction power increased.

In the embodiment of FIG. 16, the case where the extension pipe 300 and the standard suction port 400 are connected to the vacuum cleaner 100 has been described as an example, but the present invention is not limited to this embodiment. For example, the standard suction port 400 can be directly connected to the connection port 10a and used as a handheld vacuum cleaner 100. As a result, the airtightness holding member 90 enhances the airtightness with the floor surface, so that the suction force can be increased. Further, even if the airtightness holding member 90 is connected to the vacuum cleaner main body 1, the position of the connection port 10a for connecting the standard suction port 400 does not change. Therefore, the total length of the connection between the vacuum cleaner main body 1 and the standard suction port 400 should be kept short. And can improve usability.

In this way, in the vacuum cleaner 100, various accessories (attachments) can be attached / detached while the airtightness holding member 90 is attached to the vacuum cleaner main body 1, and the cleaning usage pattern can be quickly switched to perform cleaning. be able to. Further, since the airtightness holding member 90 can be left attached to the vacuum cleaner main body 1, the vacuum cleaner 100 in a handy state to which the airtightness holding member 90 is attached can perform cleaning while ensuring a high suction force.

Next, the effect of the vacuum cleaner 100 of the present embodiment will be described.
The vacuum cleaner 100 of the present embodiment includes an electric blower 40 for generating suction force and a vacuum cleaner main body 1 for accommodating the electric blower 40, and the connection port 10a (suction port) of the vacuum cleaner main body 1 is provided with. An airtightness holding member 90 for ensuring airtightness with the floor surface (surface to be cleaned) is provided. According to this, since the entire tip 90s of the airtightness holding member 90 can be brought into close contact with the floor surface (cleaned surface), the suction force can be improved and the usability can be improved.

Further, in the present embodiment, the airtightness holding member 90 is detachably provided with respect to the vacuum cleaner main body 1 (see FIGS. 2 and 3). According to this, even if the airtightness holding member 90 is damaged, the airtightness holding member 90 can be easily replaced.

Further, in the present embodiment, the vacuum cleaner main body 1 includes a light emitting element 10c that illuminates the floor surface (surface to be cleaned), and the light emitting element 10c is located behind the tip 90s of the airtightness holding member 90 (FIG. 6 and 12). According to this, due to the flashlight effect of the airtightness holding member 90, the floor surface can be irradiated in a spot manner, dust can be easily discriminated in a dark place, and cleanability can be improved.

Further, in the present embodiment, the vacuum cleaner main body 1 has an attachment (accessory) detachable, and the attachment can be attached / detached with the airtightness holding member 90 still provided on the vacuum cleaner main body 1 (FIG. 12). According to this, it is not necessary to attach / detach the airtightness holding member 90 when attaching / detaching the attachment, so that the usability of the vacuum cleaner 100 can be improved.

Further, in the present embodiment, an annular elastic portion 91a that can be elastically deformed is provided at the tip of the airtightness holding member 90. According to this, the entire tip 90s of the airtightness holding member 90 can be brought into close contact with the floor surface, the suction force can be improved as compared with the case where the airtightness holding member 90 is not brought into close contact, and dust can be reliably sucked.

Further, in the present embodiment, the electric blower 40 that generates suction force, the vacuum cleaner main body 1 that houses the electric blower 40, and the storage battery 3 that supplies electric power to the electric blower 40 and is detachably provided in the vacuum cleaner main body 1. And. The vacuum cleaner main body 1 is formed with a lead-out hole 11s from which the exhaust gas is led out from the electric blower 40, and the storage battery 3 is formed with an introduction hole 3e into which the exhaust gas led out from the lead-out hole 11s is introduced. By the way, in the vacuum cleaner equipped with the detachable rechargeable battery, the rechargeable battery could not be cooled, and the storage battery was hot or the power consumption could not be increased high. Therefore, in the present embodiment, in the removable vacuum cleaner 100, the storage battery 3 can be cooled by using the exhaust gas by communicating the lead-out hole 11s and the introduction hole 3e. As a result, it is possible to increase the output while suppressing the temperature rise of the storage battery 3.

Further, in the present embodiment, the lead-out hole 11s and the introduction hole 3e are formed at positions facing each other. According to this, the exhaust gas (air) led out from the lead-out hole 11s can be introduced into the introduction hole 3e without forming another flow path (see FIG. 14). By the way, when the lead-out hole 11s and the introduction hole 3e do not face each other, the directions of the lead-out hole 11s and the introduction hole 3e are formed toward the side, and the lead-out hole 11s and the introduction hole 3e are formed by a separate pipe. It is a case of connecting.

Further, in the present embodiment, the storage battery 3 includes a plurality of columnar cell cells 3h (battery cells), and the axial direction of the cell 3h is the same as the communication direction S (front-rear direction) in which the lead-out hole 11s and the introduction hole 3e communicate with each other. The direction (see FIG. 14). According to this, the exhaust can flow along the axial direction of the cell 3h, and the cell 3h can be cooled efficiently.

Further, in the present embodiment, the attachment / detachment direction (front-rear direction) of the storage battery 3 with respect to the vacuum cleaner main body 1 and the communication direction S (front-rear direction) are the same directions (see FIG. 10). According to this, since the holes are formed in the direction in which the storage battery 3 is pressed, it becomes easy to communicate the lead-out hole 11s and the introduction hole 3e while ensuring airtightness.

Further, in the present embodiment, the attachment / detachment direction of the storage battery 3 with respect to the vacuum cleaner main body 1 is the horizontal direction. According to this, since the weight of the storage battery 3 acts in the surface direction (the surface formed in the vertical direction and the horizontal direction) between the outlet hole 11s and the introduction hole 3e, the outlet hole 11s and the introduction hole 3e are airtight. It is hard to spoil the sex. On the other hand, when the attachment / detachment direction of the storage battery (attached upward and removed downward) and the communication direction are in the vertical direction, the weight of the storage battery acts in the direction in which the communication holes are separated from each other. , It becomes difficult to secure airtightness.

Further, in the present embodiment, one of the lead-out hole 11s and the introduction hole 3e has a convex shape, and the other has a concave shape (see FIG. 15A). According to this, the airtightness between the lead-out hole 11s and the introduction hole 3e can be improved, and the storage battery 3 can be efficiently cooled.

Further, in the present embodiment, an airtight member is provided between the lead-out hole 11s and the introduction hole 3e (see FIG. 15B). According to this, the airtightness between the lead-out hole 11s and the introduction hole 3e can be improved, and the storage battery 3 can be efficiently cooled.

FIG. 24 is a cross-sectional view showing a connection state between the main body terminal portion and the charging terminal.
As shown in FIG. 24, when the main body terminal portion 17 is fitted to the charging terminal 73, the main body terminal 17d comes into contact with the terminal 73c, and the edge portion 17f of the main body terminal 17d is further lowered, so that the terminal 73c is moved backward. It bends and deforms. Since the terminal 73c has a spring property of urging toward the front, the main body terminal 17d and the terminal 73c are maintained in contact with each other while the vacuum cleaner main body 1 is mounted on the charging stand 70. , The storage battery 3 (see FIG. 2) is continuously charged.

Further, since the charging terminal 73 is unevenly fitted with the main body terminal portion 17, for example, even if the user comes into contact with the vacuum cleaner main body 1 during charging, the main body terminal 17d and the terminal 73c are in a conductive state (contact). The state) is not released.

In the charging stand 70 configured in this way, since the charging terminal 73 is formed on the upper surface 72b of the stand portion 72, when the main body terminal portion 17 is attached to the charging terminal 73, the charging terminal 73 is located at a position close to the user's line of sight. Become. This makes it easier to insert the main body terminal portion 17 into the charging terminal 73, and makes it easier to set the vacuum cleaner main body 1 on the charging stand 70.

Further, in the charging stand 70, the charging terminal 73 is formed on the upper surface 72b of the stand portion 72. That is, since the charging terminal 73 is formed at a position higher than the floor surface, it is difficult for dust to accumulate on the charging terminal 73, and it is also possible to reduce dust rising from the floor surface and adhering to the charging terminal 73.

Further, in the vacuum cleaner 100 (see FIG. 1) set on the charging stand 70, the charging terminal 73 is located near the center of gravity of the vacuum cleaner 100 (the position of the electric blower 40 and the storage battery 3), so that the vicinity of the center of gravity is located. By receiving the charging terminal 73, the vacuum cleaner main body 1 can be stably held on the charging stand 70 during charging.

Further, by applying the vacuum cleaner 100 to the charging stand 70, the dust case 2 can be charged in a removed state, so that the dust case 2 can be charged even while it is being washed and dried.

Further, the charging terminal 73 is directed upward, and the main body terminal portion 17 is connected to the charging terminal 73 from above. As a result, the weight of the vacuum cleaner 100 can be applied to the charging terminal 73 in a focused manner, so that the main body terminal portion 17 and the charging terminal 73 can be reliably connected.

FIG. 25 is a usage pattern diagram when cleaning the floor surface with a stick-state vacuum cleaner.
In FIG. 25, the extension pipe 300 and the standard suction port 400 are connected to the vacuum cleaner 100 (with the airtightness holding member 90 attached) to make a stick state, and the vacuum cleaner 100 is projected forward from the user to raise the floor surface. When cleaning. In this case, the user can perform cleaning while moving the vacuum cleaner 100 back and forth while gripping the second grip portion 12a2 of the handle portion 12. Further, although not shown, when cleaning the floor surface with the vacuum cleaner 100 located on the left and right sides of the user, the user grips the first grip portion 12a1 of the handle portion 12. , The vacuum cleaner 100 can be moved back and forth. In this way, when the user cleans the floor surface, the position of the handle portion 12 can be changed for cleaning.

FIG. 26 is a usage pattern diagram when cleaning a high place with a stick-state vacuum cleaner.
By the way, in an electric vacuum cleaner whose center of gravity is on the tip side when it is in the stick state (see Japanese Patent Application Laid-Open No. 2016-137165), when cleaning the electric vacuum cleaner at a place higher than the floor surface, the user of the electric vacuum cleaner Since it is necessary to lift the tip upward, it becomes easy to put a burden on the wrist.

Therefore, in the present embodiment, as shown in FIG. 26, the electric blower 40 (see FIG. 6) and the storage battery 3 which are heavy objects of the vacuum cleaner 100 are located at a position close to the handle portion 12 (a position close to the hand). , The center of gravity G of the vacuum cleaner 100 is closer to the user's hand. As a result, even when the vacuum cleaner 100 is put into a stick state and the vacuum cleaner 100 is cleaned at a place higher than the floor surface, it becomes easy to clean and the usability can be improved. In FIG. 26, the case of cleaning the stairs has been described as an example, but it is also effective when the electric vacuum cleaner 100 is lifted to clean the panel of the indoor unit of the air conditioner.

Further, when the vacuum cleaner 100 is used in the stick state, when removing the dust remaining at the corner (corner) of the stairs, the extension pipe 300 and the standard suction port 400 are removed from the vacuum cleaner 100 to put it in a handy state. To do. In this case, since the airtightness holding member 90 is still attached to the vacuum cleaner 100, cleaning can be performed with the suction force increased, and it is possible to prevent unsucked dust.

Next, various applied mouthpieces connected to the vacuum cleaner 100 will be described. Various applied mouthpieces (attachments) can be attached to the vacuum cleaner 100 as an accessory for cleaning.
27A and 27B show a cross-sectional view showing a standard mouthpiece to which an opening / closing member is attached. FIG. 27A shows a forward movement, FIG. 27B shows a wall abutment, and FIG. In FIG. 27, the motor for driving the rotary brush and the substrate for controlling the rotary brush are not shown.

As shown in FIG. 27A, the standard mouthpiece 400 includes a mouthpiece case 401, a first brush 402 driven by a motor (not shown), and a second brush 403 that is driven by friction with the floor surface. And, it is configured to have.

The mouthpiece case 401 has an open lower surface and a space for accommodating the first brush 402 and the second brush 403. The second brush 403 is arranged with a gap behind the first brush 402.

Further, an opening / closing member 404 is provided on the front surface of the mouthpiece case 401. The opening / closing member 404 has a rotation shaft 404a. Further, the opening / closing member 404 has a protrusion 404b extending perpendicular to the axial direction of the rotation shaft 404a, and an opening / closing body 404c extending from the rotation shaft 404a in the direction opposite to the protrusion 404b. The protrusion 404b is made of a hard plate-like member. The opening / closing body 404c is configured by stacking a brush portion 404c1 on the front side and a rubber plate 404c2 on the rear side in the front-rear direction.

As shown in FIG. 27A, when the standard suction port 400 is advanced, the opening / closing body 404c is counterclockwise due to the frictional force between the brush portion 404c1 and the floor surface and the suction force of the electric blower 40. As it rotates, the lower part of the front surface of the mouthpiece case 401 is opened. By opening the opening / closing body 404c in this way, it becomes possible to suck in large dust (dust) located in front of the standard suction port 400.

As shown in FIG. 27 (b), when the standard suction port 400 hits the wall, the tip (upper end) of the protrusion 404b first hits the wall. Then, when the standard suction port 400 is further pressed toward the wall, the opening / closing member 404 rotates clockwise due to the pushing force at this time, and the opening / closing body 404c operates forward. When the opening / closing body 404c operates forward, the opening 401a at the lower front surface of the mouthpiece case 401 is closed. With this configuration, dust near the wall (corner) can be sucked in and removed. Further, by moving the standard suction port 400 in the left-right direction, dust near the wall can be removed more reliably.

As shown in FIG. 27 (c), when the standard suction port 400 is moved backward, the opening / closing body 404c rotates clockwise due to the frictional force between the brush portion 404c1 and the floor surface, and the opening / closing body 404c faces forward. Works on. As a result, the static pressure inside the mouthpiece case 401 increases, so that dust can be reliably sucked in.

Further, in the cordless vacuum cleaner 100, the suction power is weaker than that of the vacuum cleaner in which electric power is supplied from a household outlet. Therefore, in the standard mouthpiece 400, the front surface (opening 401a) of the mouthpiece case 401 is opened when moving forward (see FIG. 27A), so that the operating force can be lightened and a large amount of dust can be sucked. Further, when moving backward (see FIG. 27 (c)), the opening / closing member 404 closes and the static pressure increases, so that, for example, sand dust in the carpet can be sucked in firmly. Further, by making the standard suction port 400 smaller than the suction port connected to the vacuum cleaner that supplies power from a household outlet, air leakage from the standard suction port 400 can be reduced, and the static pressure is evenly distributed. It will be easier to spread.

FIG. 28 is a side view showing a stored state of the extension hose.
As shown in FIG. 28, the extension hose 800 is connected to a suction port 802 having a handle 801 at the tip, a connection port 803 connected to the vacuum cleaner main body 1 (see FIG. 2) at the base end, and a suction port 802. It is configured to include a bellows tube 804 that connects to the mouth 803. The extension hose 800 in the present embodiment can be stored in the charging stand 70 in a state where the suction port 802 and the connection port 803 are connected to form the extension hose 800 in an annular shape. By storing in this way, the extension hose 800 can be stably held in the charging stand 70.

Further, the extension hose 800 is provided with an electric wire (not shown) for connecting the suction port 802 and the connection port 803. The connection port 803 is provided with a connection terminal that is electrically connected to the vacuum cleaner main body 1, and the suction port 802 is provided with a connection terminal that is electrically connected to the extension pipe 300, the standard suction port 400, and the small suction port 600. It is provided.

By connecting such an extension hose 800 to the vacuum cleaner main body 1 and using it, the position of the small suction port 600 can be freely positioned while holding the vacuum cleaner main body 1 with one hand and the handle 801 with the other hand. Cleaning becomes possible while changing. This makes it easier to clean the seats and feet inside the vehicle compared to a vacuum cleaner without an extension hose.

Further, when the extension hose 800 is stored in the charging stand 70, the handle 801 is configured to face upward, so that the handle 801 can be easily removed from the charging stand 70. Further, since the direction of the tip 801a of the handle 801 is set to be obliquely forward and upward, when the user stands in front of the charging stand 70, the handle 801 can be gripped in the normal use state, and the extension hose 800 can be gripped. Easy to put on and take off.

When the extension hose 810 is connected to the vacuum cleaner main body 1 provided with such a handle portion 120, the tip of the vacuum cleaner main body 1 faces downward due to the center of gravity. Therefore, as shown in FIG. 29B, it is necessary to increase the length L10 of the extension hose 810.

On the other hand, the vacuum cleaner 100 of the present embodiment shown in FIG. 29A includes a handle portion 12 provided with a first grip portion 12a1 in addition to the second grip portion 12a2. Therefore, when the extension hose 800 is connected to the vacuum cleaner main body 1, the user grips the first grip portion 12a1 so that the tip of the vacuum cleaner main body 1 faces forward. Therefore, as shown in FIG. 29 (a), the length L1 of the extension hose 800 can be made shorter than that in the case of FIG. 29 (b). As a result, even when the extension hose 800 is stored in the charging stand 70, the extension hose 800 can be stored compactly.

FIG. 30 is another usage diagram of the vacuum cleaner.
