FIG. 2 is an exploded sectional view of the mouthpiece 102 when viewed from above. In FIG. 2, reference numeral 201 denotes a brush chamber having an opening facing the floor surface, and 202 denotes a brush chamber 201.
203 is a filter for separating dust and air, 204 is a connection portion between the suction body 102 and the handle 101, 205 is a front wheel, 206 is a rear wheel, and 212 is a fan of the blower 106. It is. At this time, the dust collecting chamber 107 and the blower 10
An air passage 213 connecting the six fans 212 is formed.
As shown in FIG. 2, a dust collecting chamber 107, a fan of the blower 106, and a motor 103 are arranged in a suction body behind the rotary brush 104. In detail, the fan of the blower 106 and the rotation axis of the motor 103 are

In FIG. 3, reference numeral 301 denotes an electric wire for supplying electric power to the motor, and reference numerals 302 and 303 denote elastic plate members provided in contact with the floor in order to increase the airtightness of the brush chamber 201.

In this embodiment, as described above, the dust collection chamber 10
7. Since the blower 106 and the rotary brush 104 are all arranged in the suction body, and the blower 106 and the rotary brush 104 are driven by one motor 103,
The vacuum cleaner can be made small and lightweight.

Further, since the dust collecting chamber 107, the blower 106 and the motor 103 are arranged in parallel behind the rotary brush 104, the length of the mouthpiece in the vertical direction can be shortened, and the handleability can be improved.

Further, by making the central axis of the connecting portion 204 between the mouthpiece 102 and the handle 101 the same as the central axis of the flow path (including the fan casing), the handle can be mounted not at the rear of the mouthpiece. Can be formed in the mouth,
The length of the mouthpiece in the vertical direction can be shortened, and the handleability can be improved.

Next, the operation of the first embodiment of the present invention will be described. Vacuum cleaner user handles 1 with stopper 110
After adjusting 01 to the desired length, switch 108 is turned on.
Then, the motor 103 rotates. The rotation of the motor 103 is transmitted at a reduced speed by the belt 105, and drives the rotary brush 104.

The brush or the blade of the rotary brush 104 moves the rotary brush 104 in the axial direction of the suction port 20.
It is configured with a right-hand screw twist toward 2. At this time,
By rotating the rotary brush 104 in a direction opposite to the direction of the twist (in the direction of arrow 209), the dust on the floor that is lifted up by the rotary brush 104 is sent in the direction of arrow 210. Also, the rotary brush 10
The wind generated by the rotation of 4 also flows in the direction of arrow 210 to carry dust. The cross section of the brush chamber 201 has a substantially circular shape so that the flow of dust and air is performed efficiently. Then, by the suction force generated by the fan 212 which is directly connected to the motor 103 and rotates at the same rotation speed,
Dust and air pass through the suction port 202 and pass through the dust collection chamber 107.
Sucked inside. Then, the air separated from the dust by the filter 203 passes through the inside of the connection portion 204,
After passing through the blower 106 and cooling the motor 103,
Air is exhausted to the outside of the suction body 102 from the exhaust port 111. At this time, the exhaust port 111 is configured to exhaust upward, so that dust on the floor is less likely to be scattered by the exhaust.

As described above, according to this embodiment, the flow of air in the suction body forms a U-shape in the order of the brush chamber 201, the dust collecting chamber 107, the fan 212, and the motor 103, so that a loss occurs. The number of bends can be reduced,
Therefore, dust on the floor can be efficiently cleaned with a relatively small blower output. Further, the size of the mouthpiece in the front-rear direction can be reduced.

Further, according to this embodiment, since the dust sending action by the twist of the rotary brush can be positively utilized, dust on the floor can be efficiently cleaned with a relatively small blower output.

Further, as shown in FIG. 3, the blade of the rotary brush 104 is formed of a flexible member near the mounting portion, and the brush is sewn near the tip thereof. 308 and 30
Although it is located in a bent state as shown in FIG. 9, when the rotary brush rotates in the direction of arrow 314, it rises to the positions of 310 and 311 by centrifugal force, respectively. This makes it possible to make the amount of biting of the blade into the carpet almost constant, regardless of whether the carpet is short or long, so that the load on the motor 103 can be made substantially constant. Conversely,
Considering the use of a carpet with a large load, there is no need to use a motor with large power and large power consumption,
A motor with small volume and low power consumption can be used while maintaining dust collection performance. In addition, brushes 312, 313
Has a length such that the tip of the bristles comes out below the wheels 204 and 205, and has an effect of wiping on the flooring, and has an effect of scraping out dust in the groove of the flooring. High dust collection performance. In addition, since the brushes 312 and 313 are made of a material having a weak stiffness or a small diameter, the load on the carpet does not increase so much.

That is, it is preferable that the brush or the blade is made to have a lower rigidity on the root side than the tip portion so that the brush or the blade can easily fall when it comes into contact with the surface to be cleaned. In this embodiment, when the rotary brush 104 is locked, the fan 212 is also locked, and the suction of dust itself cannot be performed. However, the brush or the blade is easily dropped, so that the rotary brush 104, that is, the fan 212 is locked. Can be prevented.

As described above, according to this embodiment, dust on the floor can be efficiently cleaned with a relatively small blower output.

Further, since the handle 101 has no motor or dust collecting chamber, it can be made very thin and light.
That is, since the motor and the dust collection chamber are provided on the suction body side, their weight is supported on the floor surface. Also, since there is no air flow at the connection between the handle 101 and the mouthpiece body 102, there is no need to consider airtightness, and the configuration can be simplified.

Further, since the gear portion 211 of the rotary brush 104 is located on the upstream side of the flow with respect to the suction port 202, dust is less likely to be entangled or wrapped around the gear portion.

As shown in FIG. 4, even when the rotating direction of the rotary brush 401 is rotated in a direction opposite to that of FIG.
When the twist direction of the brush or the blade of No. 01 is reversed (left-handed twist) from the case of FIG. 2, the moving direction of dust and air on the floor is in the same direction as that of FIG. it can.

Further, since the motor 103 can be cooled by the airflow generated by the blower, it is not necessary to use a self-cooling motor having a fan inside, and a small motor can be used.

Also, if the amount of heat generated by the motor is reduced,
As shown in FIG. 4, the motor chamber 405 and the brush chamber 201
And an air passage 406 is provided to connect a portion of the exhaust gas to the brush chamber. Thus, the dust on the floor can be separated or transported by the high-speed exhaust airflow, and high dust collection can be achieved. Further, it is possible to reduce the amount of the exhaust containing fine dust and odor that cannot be filtered by the filter 203 and emitted to the outside of the suction port.

Further, as shown in FIG. 5, by making the twist of the rotary brush 501 bilaterally symmetric, dust and air on the floor are collected at substantially the center of the suction body and sent to the dust collection chamber 503 from the suction port 502. You can also. Further, as shown in FIG. 4, when it is desired to further reduce the static pressure of the brush chamber 201 to enhance the dust collection performance, a fan 404 can be provided in the upper stage of the fan 212 to provide multiple stages. Conversely, FIG.
As shown in (2), the dust and air are pushed into the dust collecting chamber 503 by the wind pressure generated by the rotary brush 501, so that a fan is not required, the mouthpiece can be made lighter and smaller, and the power consumption can be reduced.

The vicinity of the joint between the handle 101 and the mouthpiece 102 is, as shown in FIG.
The member 304 is rotatable in a direction indicated by an arrow 315 around a rotation shaft 207 of the motor 103, and the member 305 is rotated about a shaft 306 by an arrow 3.
07 can be turned in the direction shown in FIG.
By simply twisting the grip of No. 01, the mouthpiece 102 rotates as shown by the arrow 113 in FIG. 1 and can move in the direction shown by the arrow 114 in a vertical state with respect to the traveling direction. Easy to clean.

As shown in FIG. 8, the fan 212 and the filter 203 are arranged in the longitudinal direction of the suction body, that is, substantially at the center in the direction of the rotary shaft of the rotary brush, and the portion is made large. In addition, the size of the fan 212 and the filter that require the largest area can be secured. That is, in the embodiment of FIG. 8, the case of the suction body is formed such that the height in the vertical direction of the suction body is higher at the center in the rotation axis direction of the rotary brush and lower at both ends. Lowering both ends makes it easier to clean the gap between the floor and furniture,
The mouthpiece is visually small and the feeling of pressure can be reduced. Further, in the present embodiment, in the front-back direction of the mouthpiece, the front side can be lower than the rear side, so that it is easy to clean a gap formed between the floor surface and the furniture and the like, and the suction port is visually recognized. It looks small and can reduce pressure.

As shown in FIG. 9, when the suction body 102 is lifted, the motor 1
A switch 901 for stopping the power supply to the power supply unit 03 is provided for safety during lifting.

As the battery 109, a rechargeable battery,
For example, there are a lithium ion battery, a nickel-cadonica battery, a lead battery, and the like. The battery 109 is removed and recharged by a charging stand (not shown). If a spare battery is available, the battery box 1
The cleaning operation can be resumed only by replacing the spare battery with the battery 12. Although a rechargeable battery has been described here, a primary battery such as a dry battery may be used. Since the vacuum cleaner of this embodiment has only one motor, the power consumption is small, and the cleaning time can be extended even with the same battery capacity. Alternatively, a cord may be output from the handle 101 and driven by an AC power supply. Even when the vacuum cleaner is driven by an AC power supply, the vacuum cleaner of the present embodiment consumes less power, so that the power cord may be thinner and the manipulability is good.

Embodiment 2 Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 6 is an exploded sectional view of a mouthpiece according to a second embodiment of the present invention. 601 is a motor, 602 is a rotary brush, 603 is a belt that transmits the rotation of the motor 601 to the rotary brush 602, 604 is a fan of a blower that is rotated by the motor 601 and generates suction power,
A scroll nozzle 605 constitutes a blower together with the fan 604 and efficiently guides a flow coming out of the fan.
Is a brush room, 607 is a dust collection room, 608 is a brush room 606
609 is a filter for separating dust and air, 610 is an exhaust port, 611 is a front wheel, and 612 is a rear wheel. The arrows in the figure represent the flow of air.

FIG. 7 is a cross-sectional view of a cross section perpendicular to the rotation axis of the rotary brush 602 substantially at the center of the mouthpiece. In FIG. 7, reference numeral 701 denotes a coupling portion with the handle 101;
2 is a fan 6 which turns the rotation of the motor 601 by 90 degrees.
The helical gears 703 and 704 to be transmitted to 04 are elastic plate members provided in contact with the floor in order to increase the airtightness of the brush chamber 606.

In this embodiment, as described above, the dust collecting chamber 60
7. Since the fan 604 and the rotary brush 602 are all disposed in the suction body and the motor 601 drives the fan 604 and the rotary brush 602,
The vacuum cleaner can be made small and lightweight.

Further, since the dust collecting chamber 607, the fan 604 and the motor 601 are arranged in parallel behind the rotary brush 603, the length of the mouthpiece in the vertical direction can be shortened, and the handleability can be improved.

Further, since the fan 604 and the scroll nozzle 605 are arranged horizontally, the height of the mouthpiece can be reduced.

Also, since a fan having a relatively large diameter can be attached to the size of the suction body, the fan output can be increased even with the same fan speed.
There is an effect that dust collection performance can be improved.

In each of the above embodiments according to the present invention, the driving force transmitting means for transmitting the driving force from the motor to the rotary cleaning body is not limited to the belt, but may be a gear mechanism or the like. However, it is often advantageous to use a belt in order to simplify the structure, assembly or disassembly process.
