Description

Vacuum cleaner base station

Technical Field

The present invention relates to a vacuum cleaner base station, and more particularly to a vacuum cleaner base station that collects dust inside a vacuum cleaner and has a bagless dust collecting portion.

Background technique

Generally, a vacuum cleaner is a household appliance that uses electricity to suck in air, sucks in smaller garbage or dust, and fills the dust container provided in the product, and is generally called a vacuum cleaner.

Such vacuum cleaners can be divided into manual vacuum cleaners that are directly moved by the user to perform cleaning and automatic vacuum cleaners that move autonomously to perform cleaning. Manual vacuum cleaners can be divided into canister vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, stick vacuum cleaners, and sweeping robots, etc. according to the form of the vacuum cleaner.

Although canister-type vacuum cleaners have been commonly used in the past, in recent years, there has been a trend to frequently use handheld vacuum cleaners and stick-type vacuum cleaners that improve the convenience of use by integrating a dust can and a vacuum cleaner body.

The main body and the suction port of the barrel vacuum cleaner are connected by a rubber hose or a tube, and a brush can be inserted into the suction port for use according to circumstances.

A handheld vacuum cleaner is a vacuum cleaner that maximizes portability. Although it is light in weight, it is short in length, so when sitting, the cleaning area may be limited. Therefore, it is used to clean local areas such as tables or sofas, and in cars.

A stick vacuum cleaner can be used while standing, so it can be cleaned without bending over. Therefore, it is convenient to move and clean a wider area. If a handheld vacuum cleaner cleans a narrow space, a stick vacuum cleaner can clean a wider space than a handheld vacuum cleaner, and can clean high places that cannot be reached by hand. In recent years, stick vacuum cleaners are provided in modular types, so that the type of vacuum cleaner can be actively changed and used for various objects.

In addition, in recent years, cleaning robots that autonomously clean the area without user operation have been used. The cleaning robot autonomously travels in the area to be cleaned and sucks foreign matter such as dust from the ground, thereby automatically cleaning the area to be cleaned.

In particular, since the cleaning robot is generally designed to be smaller in size in order to clean while autonomously traveling, the dust bucket for storing collected dust has a small capacity, and thus there is the inconvenience of requiring the user to frequently empty the dust bucket.

In order to solve the above inconvenience, a vacuum cleaner base station has been developed. The vacuum cleaner base station is a device for placing a sweeping robot that has finished cleaning and sucking in the dust collected by the sweeping robot. Usually, the vacuum cleaner base station has a dust collection unit that is much larger than the dust bucket of the sweeping robot. That is, it is a method in which the dust collected by the sweeping robot is continuously captured in the dust collection unit of the vacuum cleaner base station, and the user empties the dust collection unit of the vacuum cleaner base station. Accordingly, compared with the situation in which the dust bucket of the sweeping robot is emptied each time, the user has the advantage of greatly reducing the number of times the dust is emptied.

On the other hand, the types of dust collection parts can be roughly divided into bag type and bagless type. The bag type is a method in which an additional bag is provided in the dust collection part, the dust is captured in the bag, and the bag is simply separated from the vacuum cleaner base station and thrown away. Different from this, the bagless type is a method in which no additional bag is provided in the dust collection part, the dust is captured in the dust collection part itself, and the dust is emptied by separating the dust collection part itself from the vacuum cleaner base station. At this time, since the bag is a disposable consumable, it is usually formed of plastic material, so there is a cost problem of needing to purchase the bag each time and an environmental problem of causing environmental pollution. Therefore, in order to eliminate the above-mentioned disadvantages, a bagless dust collection part is often provided in the vacuum cleaner base station.

Usually, when the vacuum cleaner collects more than a certain amount of dust, the vacuum cleaner base station may flow into the collected dust from the vacuum cleaner at once, causing a large amount of dust to flow into the vacuum cleaner base station at once. At this time, when a large amount of dust flows into the bagless dust collection unit at once, the flow path will be blocked in an instant, which may cause the vacuum cleaner base station to lose its collection function.

In the prior art 1, there is disclosed an exhaust base station for emptying the dust bucket of a sweeping robot. The base station according to the prior art 1 includes a base for placing the sweeping robot with a dust bucket, and a bucket with a dust collecting part disposed inside. Dust in the air flowing into the base station in the prior art 1 moves radially inward and is filtered once in the filter and twice in the cyclone part.

However, as described above, since a large amount of dust flows into the base station at once from the vacuum cleaner, the inlet end of the dust collection unit disclosed in the prior art 1 may be caught by dust and block the flow path.

In the prior art 2, a base station capable of docking a vacuum cleaner and having a removable collection bucket is disclosed. In the prior art 2, a base station cover, a bagless collection bucket having a cyclone portion, and a removable filter are disclosed. According to the prior art 2, the collection bucket can be loaded and unloaded from the base station.

However, the prior art 2 only proposes a method of docking a vacuum cleaner to a base station or various embodiments related to a method of installing or removing a collection bucket, but does not disclose a solution for solving the problem of the flow path of the base station being blocked due to a large amount of dust flowing in at one time as described above.

That is, the base station has the feature that a large amount of dust can flow in from a vacuum cleaner at one time. However, in the prior art 1 and the prior art 2, there is a problem that the flow path is blocked by the large amount of dust. In particular, in the prior art 2, when a large amount of dust accumulates on the upper part of the filter, the air flow is hindered, and the collection performance of the base station is reduced.

Detailed ways

The advantages, features and methods of achieving the advantages and features of the present invention will be made clear by referring to the accompanying drawings and the embodiments described below. However, the present invention is not limited to the embodiments disclosed below and can be implemented in different ways. The embodiments are provided only to ensure that the disclosure of the present invention becomes complete and to clearly inform the scope of the present invention to those skilled in the art to which the present invention belongs. The present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals represent the same components.

Hereinafter, according to an embodiment of the present invention, the present invention will be described with reference to the accompanying drawings for illustrating a vacuum cleaner base station 100 .

The vacuum cleaner system is divided into a vacuum cleaner 200 and a vacuum cleaner base station 100. The vacuum cleaner 200 is a movable component that moves and sucks dust existing in the cleaning area and collects it into a dust bucket provided inside. The vacuum cleaner 200 is a fixed and immovable component that sucks dust from the vacuum cleaner 200 that has finished cleaning and collects it into a dust collection unit 140 provided inside.

The vacuum cleaner 200 of the present invention may be a cleaning robot. A cleaning robot refers to a vacuum cleaner having a driving motor and driven by the driving motor. The vacuum cleaner 200 is disposed adjacent to and below one side of the vacuum cleaner base station 100 and is combined with the vacuum cleaner base station 100 .

The combination of the vacuum cleaner 200 and the vacuum cleaner base station 100 may include: the vacuum cleaner 200 is fixed to the vacuum cleaner base station 100 and mechanically combined; the terminal of the vacuum cleaner 200 is in contact with the terminal of the vacuum cleaner base station 100 and electrically combined; the dust bucket of the vacuum cleaner 200 is connected to the dust collection part 140 of the vacuum cleaner base station 100 to allow air to flow.

The vacuum cleaner 200 includes a driving wheel (not shown). The driving wheel receives power from the driving motor of the vacuum cleaner 200 and moves the vacuum cleaner 200. The driving wheel is arranged on the bottom surface of the vacuum cleaner 200. The driving wheel can be arranged in a pair on the left and right. Gear teeth are formed on the outer peripheral surface of the driving wheel so that it can climb up the inclined surface of the coupling portion 120.

The vacuum cleaner 200 includes a caster (not shown). The caster is a component for turning the vacuum cleaner 200. The caster is configured to be rotatable around a central axis in the vertical direction. The caster is configured between the left drive wheel and the right drive wheel. The caster is configured at the front end of the vacuum cleaner 200, and as the caster rotates, the vacuum cleaner 200 can rotate.

The vacuum cleaner 200 includes an exhaust port (not shown) connected to the dust bin. The dust collected in the dust bin moves toward the vacuum cleaner base station 100 through the exhaust port. The exhaust port of the vacuum cleaner 200 is formed on the bottom surface of the vacuum cleaner 200. The exhaust port of the vacuum cleaner 200 is connected to the suction port 124 formed in the joint 120. Specifically, the exhaust port of the vacuum cleaner 200 and the suction port 124 of the joint 120 are configured to overlap each other.

The vacuum cleaner 200 includes a brush (not shown). The brush is a component that sweeps away dust adsorbed on the ground and makes it easier to be sucked in. The brush is arranged on one side of the bottom surface of the vacuum cleaner 200. The brush rotates around a central axis extending vertically.

The vacuum cleaner 200 includes a rag (not shown). The rag is a component that contains moisture and wipes the dust adsorbed on the ground to clean. The rag is arranged on one side of the bottom surface of the vacuum cleaner 200. The rag is arranged on the opposite side of the caster with the imaginary line connecting the left driving wheel and the right driving wheel as the center.

The vacuum cleaner base station 100 is a component that charges the vacuum cleaner 200 by coupling with the vacuum cleaner 200 , sucks in dust collected in a dust container of the vacuum cleaner 200 , or completely stores the vacuum cleaner 200 after cleaning.

The cover 110 forms the appearance of the vacuum cleaner base station 100 and forms a space for accommodating components therein.

The cover body 110 may be formed so that the vertical height is longer than the horizontal width or the front-back width. By having such a configuration, it is possible to minimize the space occupied in the room where the cleaner base station 100 is installed.

The cover body 110 may be composed of an upper cover 111 and side covers 112 and 113 .

The upper cover 111 is disposed on the upper surface of the housing 110 .

2 , the upper cover 111 can be opened and closed. Specifically, the rear end of the upper cover 111 is hingedly coupled to the main body of the cover 110, and rotates upward to open and close the upper surface of the cover 110. If the upper cover 111 is open, the pre-filter 161 can be detachably installed.

The first side cover 112 is disposed on the side surface of the housing 110. Specifically, the first side cover 112 is disposed on the left side surface and the front surface of the housing 110.

2 , the first side cover 112 can be opened and closed. Specifically, the rear end of the first side cover 112 is hingedly coupled to the main body of the cover 110, and rotates to the left to open and close the front of the cover 110. If the first side cover 112 is opened, the dust collection unit 140 can be detachably installed.

The second side cover 113 is disposed on the side surface of the housing 110. Specifically, the second side cover 113 is disposed on the right side surface and the back surface of the housing 110.

The second side cover 113 covers the suction flow path 130 and the discharge flow path 170. A sound-absorbing material is provided on the inner side surface of the second side cover 113, so as to block the noise generated from the inside of the housing 110 from spreading to the outside.

The coupling part 120 is a component coupled to the cleaner 200 and connected to at least one of the plurality of components of the cleaner 200. The coupling part 120 is disposed on the cover 110 and includes a coupling surface coupled to at least a portion of the cleaner 200.

The coupling portion 120 may cover the lower surface of the cover body 110 , and may be formed to extend forward of the cover body 110 .

The coupling part 120 may form an inclined surface with a lower front end and a higher rear end, so that the cleaner 200 can move from the front to the rear of the coupling part 120 and enter the coupling part 120 .

The coupling part 120 includes a driving wheel placement part 121. The driving wheel placement part 121 allows the driving wheel of the vacuum cleaner 200 to be placed on the upper part thereof. The driving wheel placement part 121 is formed by being recessed downward from the coupling surface of the coupling part 120. The driving wheel placement part 121 can be formed as a pair on the left and right corresponding to the driving wheel.

The coupling portion 120 includes a rag placement portion 122 . When the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 , the rag placement portion 122 is disposed under the rag of the vacuum cleaner 200 .

The coupling portion 120 includes a caster guide 123. The caster guide 123 is formed on a track along which the casters of the vacuum cleaner 200 pass when the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100. The caster guide 123 is formed in a groove shape that is recessed downward. The caster guide 123 extends in the front-rear direction, which is the direction in which the vacuum cleaner 200 enters.

The joint part 120 includes a suction port 124. The suction port 124 of the joint part 120 is connected to the inlet end of the suction flow path 130. The suction port 124 of the joint part 120 is communicated with the discharge port of the dust container of the cleaner 200.

The coupling part 120 includes a charging terminal 125. The charging terminal 125 is disposed at the front end of the coupling part 120 and protrudes upward. The charging terminal 125 of the coupling part 120 contacts a charging terminal (not shown) of the vacuum cleaner, so that the vacuum cleaner 200 is electrically connected to the vacuum cleaner base station 100.

The housing 110 is provided with a dust collecting unit setting space 114. The dust collecting unit setting space 114 is equivalent to a part of the internal space of the housing 110. The dust collecting unit setting space 114 is isolated from the external space by the first side cover 112 and the second side cover 113. When the first side cover 112 rotates, the dust collecting unit setting space 114 is opened, and the dust collecting unit 140 can be installed or separated.

The inlet end of the suction flow path 130 is connected to the dust bucket (not shown) of the vacuum cleaner, and the outlet end is connected to the air inlet 1411 of the dust collecting part 140. The suction flow path 130 extends forward from the inside of the joint 120. The inlet end of the suction flow path 130 is connected to the suction port 124 of the joint 120 and is connected to the dust bucket of the vacuum cleaner, so that the dust in the dust bucket of the vacuum cleaner can flow into the suction flow path 130.

The outlet end of the suction flow path 130 is arranged above the inlet end. The suction flow path 130 extends upward from the inside of the vacuum cleaner base station 100. The outlet end of the suction flow path 130 is connected to the air inlet 1411 of the dust collecting unit 140, so that the dust flowing in the suction flow path 130 can flow to the dust collecting unit 140.

Air rises from the bottom to the top inside the suction flow path 130. Since the inside of the suction flow path 130 is formed as a simple cylindrical structure, there is almost no air resistance inside. Therefore, dust contained in the air can flow to the outlet end of the suction flow path 130 without air resistance.

The dust collecting unit 140 is a component for collecting dust in the dust container of the vacuum cleaner and is accommodated in the housing 110 .

The dust collecting unit 140 of the present invention is a bagless type. The types of dust collecting units 140 are generally bag type and bagless type. The bag type is a method in which an additional bag is provided in the dust collecting unit 140, dust is collected in the bag, and only the bag is separated from the vacuum cleaner base station 100 and thrown away. Different from this, the bagless type is a method in which no additional bag is provided in the dust collecting unit 140, dust is collected in the dust collecting unit 140 itself, and the dust collecting unit 140 itself is separated from the vacuum cleaner base station 100 to empty the dust.

Usually, a certain amount of dust is collected in the vacuum cleaner 200, and the collected dust flows into the vacuum cleaner base station 100 from the vacuum cleaner 200 at one time, so a large amount of dust may flow in at one time. At this time, as too much dust flows into the bagless dust collection unit 140 at one time, the vacuum cleaner base station 100 may lose its collection function due to blockage of the flow path. Therefore, the vacuum cleaner base station 100 of the present invention has a component for removing dust caught in the discharge port and compressing the collected dust, thereby ensuring the collection function of the vacuum cleaner base station 100.

The dust collecting unit 140 includes a dust collecting body 141 , a net 144 , and a compression plate 142 .

The dust collecting body 141 forms the appearance of the dust collecting portion 140 and has an inner space capable of collecting dust.

The dust collecting body 141 is formed into a cylindrical shape with the shaft 1414 as the center. The shaft 1414 is arranged in the internal space of the dust collecting body 141 and extends in the length direction. The shaft 1414 can be arranged to be parallel to the length direction of the suction flow path 130, and specifically, the shaft 1414 can be arranged in the up-down direction. The rotating plate 1422 is rotatably coupled to the shaft 1414.

The dust collecting body 141 is formed with an air inlet 1411 for supplying air into the internal space and an air outlet 1412 for exhausting air from the internal space. The air inlet 1411 communicates with the suction passage 130 , and the air outlet 1412 communicates with the exhaust passage 170 .

The air inlet 1411 is formed on one of the multiple surfaces constituting the dust collecting body 141, except for the surface on which the air outlet 1412 is formed. For example, the air inlet 1411 is formed on one of the bottom surface, the outer wall surface, and the upper surface of the dust collecting body 141, and the air outlet 1412 can be formed on one of the bottom surface, the outer wall surface, and the upper surface of the dust collecting body 141, except for the surface on which the air inlet 1411 is formed. Referring to FIG. 7 , the air inlet 1411 is formed on the outer wall surface of the dust collecting body 141, and the air outlet 1412 is formed on the upper surface of the dust collecting body 141.

The direction in which air flows into the air inlet 1411 may be staggered from the direction in which air is discharged from the air outlet 1412. Air may flow into the air inlet 1411 in a direction intersecting the length direction of the shaft 1414, and air may be discharged from the air outlet 1412 in a direction parallel to the length direction of the shaft 1414. With this configuration, the flow direction of air inside the dust collecting body 141 is changed at least once, so that dust can be separated from the air by inertia.

The air outlet 1412 is formed on the upper surface of the dust collecting body 141. The air rises from the air outlet 1412 and is discharged to the outside of the dust collecting body 141. Therefore, the dust contained in the air cannot be discharged from the air outlet 1412 to the upper part of the dust collecting body 141 under the action of gravity and falls.

The upper cover 146 of the dust collecting part covers at least a part of the upper surface of the dust collecting body 141. The upper cover 146 of the dust collecting part is arranged to be spaced apart from the upper part of the air outlet 1412 and to be arranged to overlap with the air outlet 1412 in a vertical manner.

The upper cover 146 of the dust collecting part may be divided into a first upper cover 1461 and a second upper cover 1462 .

The first upper cover 1461 and the second upper cover 1462 may be arranged in parallel. The first upper cover 1461 and the second upper cover 1462 may be arranged to be spaced apart from each other with a predetermined interval. The first upper cover 1461 is arranged on the upper part of the second upper cover 1462.

The first upper cover 1461 is formed with a through hole through which air can be discharged.

The cyclone part 145 may be connected to the second upper cover 1462 .

A dust outlet 1413 for discharging collected dust is formed in the dust collecting body 141. Referring to Fig. 7, the dust outlet 1413 is formed on the lower surface of the dust collecting body 141.

The discharge cover 143 covers the dust discharge port 1413. Referring to Fig. 7, the discharge cover 143 is disposed on the lower surface of the dust collecting body 141. The discharge cover 143 is hingedly coupled to the dust collecting body 141, so that the dust discharge port 1413 is opened and closed while rotating.

The discharge cover 143 may be provided with a power transmission member 1425 .

The net 144 is a component for filtering dust from the air exhausted from the dust collecting body 141. The net 144 covers the air exhaust port 1412.

A plurality of holes are formed in the net 144. The net 144 may be woven from a plurality of steel wires, thereby forming a plurality of holes.

The net 144 filters dust from the air by a physical method. That is, dust smaller than the holes of the net 144 passes through the net 144, and dust larger than the holes of the net 144 cannot pass through the net 144. Large dust that cannot pass through the net 144 falls to the lower part of the dust collecting body 141, or is adsorbed on the lower surface of the net 144.

The net 144 is arranged to be spaced apart from the shaft 1414 toward the radial outer side.

The net 144 may be formed in a semicircular shape. At this time, the net 144 may be formed to be convex toward the radial outside.

The compression plate 142 is a component that compresses the dust collected in the internal space of the dust collecting body 141. The compression plate 142 is rotatably arranged in the internal space of the dust collecting body 141, and rotates to clean the net 144.

The first function of the compression plate 142 is to compress the dust collected in the inner space of the dust collecting body 141 , and the second function is to sweep away the dust adsorbed on the net 144 .

The compression plate 142 may be composed of a fixed plate 1421 , a rotating plate 1422 , and a web cleaner 1423 .

10 , the fixing plate 1421 extends from the outer wall of the dust collecting body 141 toward the shaft 1414 .

The fixing plate 1421 may be formed integrally with the dust collecting body 141. The fixing plate 1421 protrudes from the dust collecting body 141 and extends radially inward. The inner end of the fixing plate 1421 may be adjacent to the shaft 1414 and spaced apart from the shaft 1414. Therefore, the fixing plate 1421 does not hinder the rotation of the rotating plate 1422.

The fixing plate 1421 extends along the length direction of the shaft 1414 .

The fixing plate 1421 may be formed in a flat plate shape.

10 , the rotating plate 1422 is rotatably coupled to the shaft 1414 and extends radially outward.

The rotating plate 1422 surrounds at least a portion of the outer circumferential surface of the shaft 1414. The rotating plate 1422 includes a cylindrical shape having a hollow into which the shaft 1414 may be inserted.

The rotating plate 1422 extends radially outward. The outer end of the rotating plate 1422 is adjacent to the inner circumferential surface of the dust collecting body 141, but is spaced apart from the dust collecting body 141. Therefore, the rotating plate 1422 can rotate with the shaft 1414 as the rotation center axis.

When the rotating plate 1422 rotates, the rotating plate 1422 can be arranged in an imaginary space formed by the air inlet, the central axis of the shaft and the fixed plate 1421. Through this configuration, when the rotating plate 1422 rotates, the dust is pushed to the space where the air does not flow, thereby not hindering the air flow inside the dust collecting body.

10 , the operation of the compression plate 142 will be described.

FIG. 10( a ) is a diagram showing a state before the compression plate 142 moves, and FIG. 10( b ) is a diagram showing a state after the compression plate 142 moves.

Referring to (a) in FIG10 , the fixing plate 1421 is arranged at the three o'clock direction and the compression plate 142 is arranged at the six o'clock direction with the axis 1414 as the center. The air inlet 1411 is arranged at the one o'clock direction of the axis 1414, and although not shown in the figure, the air outlet 1412 is arranged at the nine o'clock direction of the axis 1414. Therefore, dust can exist in the one o'clock direction to the nine o'clock direction with the axis 1414 as the center.

10 (b), the rotating plate 1422 rotates clockwise (CW) around the shaft 1414, and finally rotates to the two-point direction of the shaft 1414. At this time, the dust inside the dust collecting body 141 is compressed and located between the rotating plate 1422 and the fixed plate 1421.

After (b) in Figure 10, the rotating plate 1422 can return to the state of (a) in Figure 10. In the state of (b) in Figure 10, the dust flowing into the dust collecting body 141 can be located in the space at the four o'clock direction of the shaft 1414, and is compressed as the rotating plate 1422 rotates counterclockwise (CCW), and finally located at the four o'clock direction of the shaft 1414.

The net cleaner 1423 is a component that removes dust adsorbed to the net 144. The net cleaner 1423 is disposed at the upper end of the rotating plate 1422.

The inner end of the web cleaner 1423 may extend to the inner end of the rotating plate 1422 , and the outer end may extend to the outer end of the rotating plate 1422 .

The net cleaner 1423 extends upward from the upper end of the rotating plate 1422. The upper end of the net cleaner 1423 can contact the net 144, and as the rotating plate 1422 rotates, the dust adsorbed on the lower surface of the net 144 is swept away.

The net cleaner 1423 may include a material having elasticity. For example, a portion of the net cleaner 1423 may be formed of a rubber material.

The rotating plate 1422 can be operated using a compression motor 1424 and a power transmission member 1425 .

The compression motor 1424 is a component that generates power for driving the rotating plate 1422. The compression motor 1424 is disposed on one side of the dust collecting unit 140 and on the opposite side of the air outlet 1412, and transmits power to the rotating plate 1422.

6 , the compression motor 1424 is disposed at the lower portion of the dust collecting unit 140 . The compression motor 1424 is disposed outside the discharge cover 143 , and transmits power to the rotating plate 1422 disposed in the inner space of the dust collecting unit 140 through the discharge cover 143 .

The compression motor 1424 can rotate in two directions. FIG10(a) is a diagram showing the compression motor 1424 rotating in a first direction, and FIG10(b) is a diagram showing the compression motor 1424 rotating in a second direction.

The shaft 1414 connected to the compression motor 1424 can be arranged in parallel with the shaft 1414 connected to the dust collecting motor 150. Specifically, the shaft 1414 connected to the compression motor 1424 and the shaft 1414 connected to the dust collecting motor 150 can be arranged on the same shaft. Therefore, one motor can also perform the functions of the compression motor 1424 and the dust collecting motor 150 at the same time.

The power transmission member 1425 is a component that transmits the power of the compression motor 1424 to the rotating plate 1422 .

The power transmission member 1425 may be composed of at least one gear.

The power transmission member 1425 may be disposed at the discharge cover 143. At this time, the power transmission member 1425 may include a seal (not shown) to separate the inner space and the outer space of the dust collection part 140.

The dust collecting portion 140 is configured to be attachable to or detachable from one side of the housing 110 .

The direction in which the dust collecting unit 140 is inserted into the housing 110 and the direction in which the pre-filter 161 is inserted into the housing 110 intersect each other. Referring to Fig. 2, the dust collecting unit 140 is inserted from the front of the housing 110 toward the rear for installation, and is pulled out toward the front for separation. This is in contrast to the pre-filter 161 being inserted from the upper part of the housing 110 toward the bottom.

The handle 181 is a component for the user to hold when the dust collecting unit 140 is separated from the cover body 110. The handle 181 is rotatably coupled to the dust collecting unit 140.

When the dust collecting unit 140 is separated, the handle 181 is rotated. Referring to (b) in FIG. 4 , when the dust collecting unit 140 is separated, the handle 181 is rotated in the clockwise direction and protrudes toward the front of the dust collecting unit 140. The user can separate the dust collecting unit 140 by holding the handle 181 and pulling it forward. The handle 181 can be rotatably coupled to the dust collecting unit, and only rotates and protrudes toward the front when separated. When the handle 181 is installed, it occupies a minimum space in the internal space of the vacuum cleaner base station 100, so that the internal space can be used efficiently.

A handle insertion groove 1415 is formed in the dust collecting body 141. The handle insertion groove 1415 forms a space for inserting the handle 181 when the handle 181 is installed. The handle insertion groove 1415 is formed to be recessed inward from one side of the dust collecting body 141. When the handle 181 is installed, the handle 181 rotates sideways around the rotation center axis and is inserted into the handle insertion groove 1415.

The handle 181 is hingedly coupled to the dust collecting body 141. The handle hinge 182 is formed protruding from one side of the dust collecting body 141. The handle hinge 182 is inserted into one side of the handle 181, or penetrates the handle 181. In the case where the handle hinge 182 penetrates the handle 181, the fastening member 183 may be fastened to the end of the handle hinge 182.

The rotation center axis of the handle 181 can be arranged in parallel with the rotation center axis of the compression plate 142. Referring to FIG6 , the rotation center axis of the handle 181 is arranged in the up-down direction. Referring to FIG6 (a), when the dust collecting unit 140 is installed, the handle 181 rotates counterclockwise around the rotation center axis and is inserted into the handle insertion groove 1415. In addition, referring to FIG6 (b), when the dust collecting unit 140 is separated, the handle 181 rotates clockwise around the rotation center axis and protrudes toward the front of the dust collecting unit 140.

The handle 181 can be divided into a horizontal portion 1811 and a vertical portion 1812. At first glance, the horizontal portion 1811 of the handle extends radially outward from the dust collecting body 141. A handle hinge 182 is inserted or penetrated at the inner end of the horizontal portion 1811 of the handle. The vertical portion 1812 of the handle is bent at the outer end of the horizontal portion 1811 of the handle and extends in a direction different from the extension direction of the horizontal portion 1811. Specifically, the vertical portion 1812 of the handle extends in a direction perpendicular to the extension direction of the horizontal portion 1811.

The pre-filter 181 is a component for filtering dust from the air. Specifically, the pre-filter 161 is arranged upstream of the high efficiency air filter, and filters large dust from the air flowing into the high efficiency air filter at one time.

The pre-filter 161 is disposed at an upper portion of the dust collecting portion 140 , and communicates with the air outlet 1412 of the dust collecting portion 140 .

The pre-filter 161 is disposed on the upper portion of the dust collecting portion 140, and the dust between the pre-filter 161 and the dust collecting portion 140 falls under the action of gravity and is deposited in the dust collecting portion 140. According to the present invention, since the capacity of the dust collecting portion 140 is smaller than the capacity of the pre-filter 161, the dust is captured in the dust collecting portion 140 as much as possible, thereby ensuring the capture capacity of the vacuum cleaner base station 100 to the maximum extent.

The pre-filter housing 1611 forms the appearance of the pre-filter 161 , and a space for accommodating the filter member 1614 is formed therein.

The filter element 1614 of the pre-filter is a component for separating dust from the air flowing into the pre-filter 161. The filter element 1614 of the pre-filter separates dust from the air by a physical method. That is, the filter element 1614 of the pre-filter has a plurality of through holes, allows dust smaller than the through holes to pass through, and filters out dust larger than the through holes.

In the pre-filter 161, the air flows in in a parallel direction and is discharged in a cross direction, based on the direction in which the air outlet 1412 of the dust collecting body 141 is discharged. Referring to Figure 11, an inlet 1612 is formed on the lower surface of the pre-filter 161, and an outlet 1613 is formed on the side. Therefore, the air flows upward toward the pre-filter 161 and is discharged from the pre-filter 161 to the side. With this configuration, the flow direction of the air inside the pre-filter 161 can be changed at least once, and can pass through the surface of the filter element 1614 uniformly as a whole.

The inlet 1612 of the prefilter may be arranged to be inclined toward one side with reference to an imaginary center line that divides the prefilter 161 into left and right parts. The outlet 1613 of the prefilter may be formed to be long in one direction.

The pre-filter 161 can be installed or separated in a direction that is staggered from the direction in which the dust collecting part 140 is installed or separated. The direction in which the pre-filter 161 is installed or separated from the cover body 110 and the direction in which the pre-filter 161 is installed or separated from the cover body 110 intersect each other. Referring to FIG. 2 , when the upper cover 111 is open, the pre-filter 161 moves downward toward the upper surface of the cover body 110 and is installed. On the contrary, the pre-filter 161 moves upward from the cover body 110 and is separated. This is in contrast to the installation or separation of the dust collecting part 140 to the front or rear of the cover body 110.

The front end of the pre-filter 161 is configured to be closer to the upper part than the rear end. In more detail, referring to Figure 12, the front end of the filter member 1614 of the pre-filter is configured to be closer to the upper part than the rear end. By this configuration, the direction of the air flow inside the pre-filter 161 can be configured to be as close to vertical as possible from the surface of the filter member 1614.

The inlet 161 of the pre-filter faces the lower surface of the filter element 1614, and the outlet faces the upper surface of the filter element 1614. Therefore, when a large amount of dust is filtered in the filter element 1614, it falls to the lower part of the filter element 1614 under the action of gravity, thereby preventing dust above a certain amount from being adsorbed on the filter element 1614 and ensuring the minimum air flow.

The inlet end of the exhaust flow path 170 is communicated with the air exhaust port 1412 of the dust collecting unit 140 , and the outlet end is communicated with the outside at one side of the cover body 110 .

The exhaust flow path 170 is connected to the outside of the cleaner base station 100 through the pre-filter 161 - the suction motor - the high efficiency air filter.

The discharge flow path 170 may be arranged in parallel with the suction flow path 130 .

The outlet end of the discharge flow path 170 is arranged at a lower portion than the inlet end. That is, inside the discharge flow path 170, the air descends from the upper portion to the lower portion.

The diameter of the cross section of the discharge flow path 170 in the first direction may be greater than the diameter in the second direction. Unlike the circular cross section of the suction flow path 130, the cross section of the discharge flow path 170 may be formed in an elliptical shape.

The dust collecting part 140 may be provided with a cyclone 145 . The cyclone 145 is a component that separates dust from the air using centrifugal force. The cyclone 145 is provided on the outer peripheral surface of the dust collecting body 141 and communicates with the air outlet 1412 .

The cyclone portion 145 is disposed downstream of the air inlet 1411 of the dust collecting body 141 and upstream of the air outlet 1412 .

The cyclone 145 is disposed on the outer peripheral surface of the dust collecting body 141. Referring to Fig. 7, the dust collecting body 141 is formed as a cylinder, and the cyclone 145 may be disposed to surround at least a portion of the outer peripheral surface of the dust collecting body 141.

The cyclone part 145 may be formed integrally with the dust collecting body 141. Although not shown, unlike the above, the cyclone part 145 may be formed separately from the dust collecting body 141 and then combined.

The cyclone part 145 may be divided into an outer tube and an inner tube. The outer tube of the cyclone part 145 is formed as one body with the dust collecting body 141. The inner tube of the cyclone part 145 may be formed at the upper cover 146 of the dust collecting part 140, specifically, at the second upper cover 1462.

The central axis of the inner tube of the cyclone 145 is arranged on the same line as the central axis of the outer tube. Therefore, the air flowing into the cyclone 145 performs a spiral motion in the space between the inner tube and the outer tube, and the dust is separated by centrifugal force. The separated dust falls to the lower part of the cyclone 145, and the air is discharged to the outside through the inner space of the inner tube.

The air discharged from the cyclone unit 145 is directed toward the pre-filter 161 through the air discharge port 1412 formed in the first upper cover 1461 .

The dust collecting motor 150 is a component that generates a flow of air inside the cleaner base station 100. The dust collecting motor 150 is disposed between the cleaner 200 and the dust collecting unit 140 when the cleaner 200 is coupled.

The dust collecting motor 150 is disposed at an upper portion of the cleaner 200 , and is disposed at a lower portion of the dust collecting portion 140 .

The dust collecting motor 150 is disposed above the high efficiency air filter and is disposed below the pre-filter 161 .

The dust collecting motor 150 is disposed below the compression motor 1424 .

The pre-filter 161 is disposed on the opposite side of the dust collecting motor 150 with the dust collecting portion 140 as the center.

The pre-filter 161 and the HEPA filter are spatially separated. Specifically, the pre-filter 161 is disposed on the opposite side of the HEPA filter with the dust collecting unit 140 as the center. The pre-filter 161 is disposed on the opposite side of the HEPA filter with the dust collecting motor 150 as the center.

The compression motor 1424 is arranged on the same side as the dust collecting motor 150 with the dust collecting unit 140 as the center. That is, the compression motor 1424 and the dust collecting motor 150 can be arranged adjacent to each other. The compression motor 1424 and the dust collecting motor 150 are both components that generate noise. Therefore, the compression motor 1424 and the dust collecting motor 150 are arranged in one space, and the noise component is arranged to surround the space, so that the noise generation of the vacuum cleaner base station 100 can be suppressed to the maximum extent by minimizing the noise component.

The air flow of the vacuum cleaner base station 100 of the present invention constructed as described above is described as follows. If the vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the dust bucket of the vacuum cleaner 200 is connected to the suction flow path 130 of the vacuum cleaner base station 100. If the dust collecting motor 150 is running, the air is discharged to the outside of the vacuum cleaner base station 100 through the suction flow path 130-dust collecting part 140-cyclone part-prefilter 161-discharge flow path 170-dust collecting motor 150-high efficiency air filter. At this time, an ascending flow path is formed from the suction flow path 130 to the prefilter 161, and a descending flow path is formed from the prefilter 161 to the high efficiency air filter.

The operation of the vacuum cleaner base station 100 of the present invention configured as described above will be described below.

The dust collecting part 140 of the present invention separates dust from the dust flowing in. An air outlet 1412 is formed on the upper surface of the dust collecting part 140 , and a net 144 is arranged at the air outlet 1412 so that air can pass through the net 144 but dust cannot pass through the net 144 .

The dust collecting unit 140 is provided with a compression plate 142. The compression plate 142 is rotatably coupled to the shaft 1414 of the dust collecting body 141. Specifically, if the rotating plate 1422 rotates, the dust collected inside the dust collecting body 141 is compressed by the rotating plate 1422 and the fixed plate 1421. As the dust is compressed and reduced in volume, the dust collecting unit 140 can additionally collect more dust, and the operation time of the vacuum cleaner base station 100 can be increased.

The compression plate 142 is provided with a net cleaner 1423. The net cleaner 1423 is provided at the upper end of the rotating plate 1422, and when the rotating plate 1422 rotates, the net cleaner 1423 removes the dust adsorbed on the net 144. Therefore, it is possible to prevent the air flow from being obstructed by the dust adsorbed on the net 144, and to prevent the performance of the vacuum cleaner base station 100 from being degraded.

The preferred embodiments of the present invention are shown and described above, but the present invention is not limited to the above-mentioned specific embodiments. Without departing from the gist of the present invention as requested by the scope of the claims, a person skilled in the art to which the present invention belongs can perform various modified implementations, and these modified implementations cannot be understood separately from the technical ideas or prospects of the present invention.
