Description

vacuum cleaner station

The present invention relates to a cleaner station coupled to a cleaner to collect dust inside a dust bin of the cleaner.

Stick vacuum cleaners (hereinafter, referred to as 'cleaners') have a small capacity of dust bins for storing collected dust, so users have to empty the dust bins every time.

Therefore, the use of a cleaner station configured to collect dust in a dust bin by sucking in through a suction force of a dust collecting motor so that a user does not manually remove dust in the dust bin is being widely used.

The cleaner station includes a housing, a dust collecting motor disposed inside the housing, and a dust bag-shaped collecting part accommodating collected dust, and is configured to be coupled with a vacuum cleaner or a dust bin of the vacuum cleaner.

The vacuum cleaner station is convenient in that it can automatically empty the dust bin of the vacuum cleaner, and since the dust bag included in the vacuum cleaner station has a larger volume than dust bins included in most vacuum cleaners, the dust disposal cycle is longer.

On the other hand, the collecting unit in the form of a dust bag has an advantage in terms of user convenience because the configuration is simple and the entire dust bag can be thrown into the trash without the need to separately remove dust or wash the inside.

However, since the inside of the dust bag cannot be cleaned, it must be purchased and exchanged periodically, so some users may feel a burden in terms of cost.

In this regard, US Patent Registration No. 10595692 is proposed as a prior patent document.

The prior patent document discloses an embodiment of a discharge station having a collecting unit in the form of a bin as a discharge station docked with a robot cleaner.

Unlike the dust bag, the 'tub' type of collection part has the advantage of being able to be used semi-permanently once only the dust contained in it is removed because it is easy to clean the inside.

However, there may be users who find it cumbersome to remove dust and wash, which are separate tasks.

As such, when the shape of the collecting unit is fixed to one type, it is difficult to satisfy the preferences of different users.

Meanwhile, US Patent Registration No. 10595692 discloses an embodiment of a discharge station including a canister in the form of a bin and a dust separator as a discharge station docked with a robot cleaner.

In one embodiment disclosed in the prior patent document, the dust separator is configured in a conical shape to use the principle of centrifugal separation and is included inside the canister. In another embodiment disclosed in the prior patent document, the dust separated from the multi-stage separation device disposed above the canister is collected in the canister.

However, the station can only be combined with a robot cleaner, and has a limitation in that it does not have a structure capable of collecting dust stored in the stick cleaner by combining the stick cleaner.

In addition, the above prior patent documents have a structure in which air sucked from the dust bin of the robot cleaner flows into the side of the dust bin. In this way, when air is introduced into the side of the dust bin, there is a high possibility that the introduced dust may flow backward.

In addition, the prior patent document also discloses an embodiment in which the dust separator is not included. An embodiment without a dust separator includes a filter wall inside the canister, the filter wall is provided in the form of an annular ring, and dust-laden air sucked into the canister is configured to be exhausted after passing through the filter wall.

However, in the case of an embodiment including only a filter wall without including a dust separator, a lot of unseparated dust inevitably flows into the filter wall instantaneously, which reduces the lifespan of the filter wall and shortens the replacement cycle.

In addition, there is a need to develop a cleaner station having a structure capable of extending the dust emptying cycle even when the dust storage member includes a foreign matter storage member having a capacity such that the user must manually empty the dust collected in the foreign matter storage member.

An object of the present invention is to provide a cleaner station that can select and use a dust bag or a dust bin according to a user's preference.

Another object of the present invention is to provide a cleaner station including a dust bin having increased dust storage capacity and efficiency to have a long dust emptying cycle.

Air passing through the dust inlet can flow in the direction of the mesh through the guide wall and the inlet cover.

The collecting unit may include a compression rotating unit rotatably provided on the collecting unit body and moving the dust collected in the collecting unit body.

By rotating the compression rotation unit, the dust may be compressed, and the collecting capacity in the collecting unit may be increased.

At least a portion of the compression rotating unit may be disposed below the inlet cover.

The compression rotating unit may include a rotating shaft member rotating within the collecting unit body; and a rotation plate connected to the rotation shaft member and moving dust, and an upper end of the rotation plate may be disposed farther from the ground than an upper end of the rotation shaft member.

A distance from a rotating shaft of the inlet cover to the rotating plate may be greater than a diameter of the inlet cover.

Therefore, it is possible to prevent the inlet cover and the compression unit from interfering with each other.

The collecting unit passage may be formed along a direction perpendicular to the ground.

According to the present invention, a user may place either a tub-shaped first collecting unit in which the size of the dust receiving space is fixed, or an envelope-shaped second collecting unit in which the size of the dust receiving space is variable, to the cleaner station. Since it can be used in combination, it has the advantage of being able to satisfy various tastes of users who prefer different types of collecting parts.

Here, the forward direction may mean a direction in which the push protrusion 351 presses the coupling lever 222c. Also, the reverse direction may refer to a direction in which the push protrusion 351, which presses the coupling lever 222c, returns to its original position. The forward direction may be the reverse direction and the opposite direction.

The cover opening gear 353 is coupled to the cover opening motor 352 and may move the push protrusion 351 by using power of the cover opening motor 352 . Specifically, the cover opening gear 353 may be accommodated inside the gear box 355 . The driving gear 353a of the cover opening gear 353 may be coupled to the motor shaft of the cover opening motor 352 to receive power. The driven gear 353b of the cover opening gear 353 may be coupled with the push protrusion 351 to move the push protrusion 351 . For example, the driven gear 353b is provided in the form of a rack gear, meshes with the driving gear 353a, and can receive power from the driving gear 353a.

At this time, the discharge cover 222 may be provided with a torsion spring 222d. By the elastic force of the torsion spring 222d, the discharge cover 222 can be rotated more than a predetermined angle and supported in the rotated position. Accordingly, the discharge cover 222 may be opened, and the dust passage hole 321a may communicate with the inside of the dust container 220 .

The gear box 355 is provided inside the housing 310, is disposed below the coupling part 320 in the gravitational direction, and the cover opening gear 353 may be accommodated therein.

According to the present invention, the user can open the dust bin 220 without separately opening the discharge cover 222 of the vacuum cleaner by the cover opening unit 350, thereby improving convenience.

In addition, since the discharge cover 222 is opened while the first cleaner 200 is coupled to the cleaner station 300, scattering of dust can be prevented.

10 is a diagram for explaining arrangement between components of cleaner stations in an embodiment of the present invention.

Referring to FIG. 10 , the cover opening unit 350 described above is disposed below the coupling part 320, and the flow path part 380 is disposed to the rear side of the coupling part 320 and the cover opening unit 350.

Hereinafter, a flow path extending from the coupler 320 to the collecting unit 500 is referred to as a first flow path 381 . The collecting unit 500 for collecting dust is connected to and disposed at the lower end of the first flow path 381 .

The cleaner station 300 may further include a chamber unit 360 .

The chamber unit 360 is disposed in the housing 310 and a collecting unit receiving space 360a is formed to accommodate the collecting unit 500 .

At this time, the collecting unit 500 may be detachably provided in the chamber unit 360 . The chamber unit 360 may be detachably provided in the housing 310 or may be integrally formed with the housing 310 . A detailed structure of the chamber unit 360 will be described below in FIG. 11 .

The cleaner station 300 may include a flow path part 380 .

The flow path part 380 is defined as a passage through which air and foreign matter exiting the dust bins 110 and 220 of the cleaners 100 and 200 flow. The flow path part 380 includes a first flow path 381 connecting the dust bin 220 of the first cleaner 200 and the collecting unit 500, and a second flow path connecting the collecting unit 500 and the dust collection motor 391. 382 and a third passage 383 connecting the dust bin 110 of the second cleaner 100 and the first passage 381.

The first passage 381 may be disposed on the rear side of the coupling surface 321 . The first flow path 381 may refer to a space formed between the dust bin 220 of the first cleaner 200 and the collecting unit 500 to allow air to flow. For example, the first passage 381 may be a space surrounded by structures. For example, the first flow path 381 may be an inner space of a hollow tube.

When the first cleaner 200 is coupled to the cleaner station 300 and the dust passage hole 321a is opened, the first flow path 381 includes a first area 381a communicating with the inner space of the dust bin 220 and the first channel 381 . It may include a second region 381b that communicates the first region 381a and the collecting unit 500 (see FIG. 8).

Accordingly, when the dust collecting motor 391 is operated, dust in the dust bin 220 of the first cleaner 200 may flow to the collecting unit 500 through the first flow path 381 .

The second passage 382 may connect the collecting unit 500 and the dust suction module 390 . That is, air from which dust is separated while passing through the collecting unit 500 may be guided to the dust collecting motor 391 through the second flow path 382 .

The second passage 382 may refer to a space formed to allow air to flow between the collecting unit 500 and the dust suction module 390 . The second passage 382 may be formed surrounded by a structure.

In an embodiment in which the collecting part 500 is the first collecting part 510 , a partial area of the second passage 382 may be formed inside the first collecting part 510 . The partial area may be referred to as a collecting part passage 518 . The collector passage 518 may be disposed on the front side of the collector body 511 (see FIGS. 24 and 26).

The third passage 383 is disposed inside the housing 310 and is connected to the dust bin 110 of the second cleaner 100 .

The third passage 383 may connect the dust bin 110 of the second cleaner 100 and the collecting unit 500 .

The third passage 383 may be formed backward from the lower coupling part 314 and formed upward after being bent. Also, an upper end of the third passage 383 may mean a passage formed in a shape bent at a predetermined angle.

That is, in a state in which the second cleaner 100 is coupled to the cleaner station 300 , one end of the third passage 383 is connected to the dust bin 110 of the second cleaner 100 . Also, the other end of the third flow path 383 may be connected to the first flow path 381 .

Meanwhile, according to embodiments, the third passage 383 may be connected to the collecting unit 500 through the passage conversion module 384 .

With this configuration, the third passage 383 may collect dust stored in the second cleaner 100 disposed closer to the ground than the collecting unit 500 .

Accordingly, dust in the dust bin 110 of the second cleaner 100 may move to the collecting unit 500 through the third passage 383 .

Meanwhile, the cleaner station 300 according to the embodiment of the present invention may further include a passage conversion module 384 .

The passage conversion module 384 may selectively communicate the collecting unit 500 with the dust bin 220 of the first cleaner 200 or the dust bin 110 of the second cleaner 100 .

For example, the passage conversion module 384 selectively opens and closes the first passage 381 and the third passage 383 to selectively open and close the first passage 381 or the third passage 383 with the collecting unit 500. can be communicated with.

As another example, the flow path conversion module 384 has a connection flow path formed on the lower side to communicate with the collecting unit 500, and the upper side may be provided to selectively communicate with the first flow path 381 or the third flow path 383. there is.

Accordingly, when only the first cleaner 200 is coupled to the cleaner station 300, the passage switching module 384 connects the first passage 381 and the collecting unit 500, and connects the third passage 383 to the collection unit 500. The connection of the unit 500 may be blocked.

In addition, when only the second cleaner 100 is coupled to the cleaner station 300, the passage switching module 384 connects the third passage 383 and the collecting unit 500, and connects the first passage 381 to the collecting unit 500. The connection of the unit 500 may be blocked.

Through this, it is possible to prevent a decrease in suction power caused by the simultaneous opening of the plurality of passages 381 and 383 .

The cleaner station 300 may include a dust suction module 390 .

Referring back to FIG. 10 , the dust suction module 390 may include a dust collecting motor 391 . The dust collecting motor 391 may be disposed under the collecting unit 500 . The dust collecting motor 391 may generate a suction force to the flow path part 380 . Through this, a suction force capable of sucking dust into the dust bin 220 of the first cleaner 200 is provided.

The dust suction module 390 may further include a HEPA filter (not shown). The HEPA filter may be disposed at a rear end of the dust collecting motor 391 (based on an air flow path). As a result, clean air is discharged to the outside of the housing 310 .

Meanwhile, although not shown in FIG. 10 , the fixing unit 330 and the door unit 340 are disposed adjacent to the coupling part 320 , which has already been described with reference to FIGS. 6 to 8 .

The cleaner station 300 may further include a collecting unit 500 .

11 is a perspective view showing a chamber unit 360 and a collecting unit 500 in a form coupleable to the chamber unit 360 according to an embodiment of the present invention.

The collecting unit 500 may be detachably coupled to the chamber unit 360 . A dust accommodating space is provided in the collecting unit 500 to collect dust sucked from the inside of the dust bin 220 by the dust collecting motor 391 .

Meanwhile, the collecting unit 500 according to the embodiment of the present invention may be a first collecting unit 510 having a tubular shape in which the size of the dust receiving space is fixed.

Since the first collecting unit 510 is in the form of a 'tub', it is easy to clean the inside, so that it can be used semi-permanently if only the received dust is removed. However, dust removal and cleaning, which are tasks that must be performed separately, may be cumbersome to the user.

Alternatively, the collecting unit 500 according to the embodiment of the present invention may be an envelope-shaped second collecting unit 520 in which the size of the dust accommodating space is variable.

The second collecting unit 520 is typically made of a breathable material that allows air to escape but dust cannot escape. The second collecting unit 520 has a problem in that it needs to be purchased and replaced periodically since the inside of the second collecting unit 520 cannot be cleaned even if the received dust is removed. (520) It has an advantage in terms of user convenience because it can be thrown in the trash as a whole.

The cleaner station 300 according to an embodiment of the present invention can be operated even when any one of the two types of collecting parts 510 and 520 is accommodated in the collecting part accommodating space 360a in the chamber part 360 . That is, the two types of collecting units 510 and 520 are compatible.

The user may select the collecting unit 510 or 520 to be used in consideration of the above-described advantages and disadvantages of each of the collecting units 510 and 520 and the user's preference.

The benefits of compatibility are not limited to the realm of user preferences. For example, there is also an advantage that a user who prefers the first collecting part 510 can temporarily use the second collecting part 520 as an alternative in the process of washing and drying the first collecting part 510 .

Hereinafter, various features provided in the chamber unit 360 will be described so that the collecting units 510 and 520 of different shapes can be compatible with each other.

12 is a cross-sectional view of the chamber unit 360 viewed from the side in an embodiment of the present invention, and FIG. 13 is an enlarged cross-sectional view of the upper side of the chamber unit 360 in the embodiment of the present invention, 14 is a front view of the chamber 360 according to an embodiment of the present invention, and FIG. 15 is a perspective view showing the internal structure of the chamber 360 according to an embodiment of the present invention. 16 is a cross-sectional view showing the compression drive unit 362 in the embodiment of the present invention.

First, referring back to FIG. 11 , the chamber unit 360 may include a chamber body 361 .

The chamber body 361 forms the exterior of the collecting unit accommodating space 360a. The collecting unit accommodating space 360a may have a substantially hexahedral shape.

One side of the chamber body 361 may be open. One open side of the chamber body 361 may be a front side. One open side of the chamber body 361 may be closed by the housing cover 370 .

One side of the housing cover 370 may be rotatably coupled to one side of the housing 310 . When the other side of the housing cover 370 rotates in a direction away from the housing 310, one side of the chamber body 361 is opened. Conversely, when the other side of the housing cover 370 rotates in a direction closer to the housing 310, one side of the chamber body 361 may be closed.

The collecting unit receiving space 360a formed by the chamber body 361 may have a cross-sectional area of a front end larger than a cross-sectional area of a rear end.

More specifically, referring to FIG. 12 , an imaginary plane p1 connecting the front upper end and the rear upper end of the chamber body 361 may have a backward-downward slope.

An imaginary plane p2 connecting the front lower end and the rear lower end of the chamber body 361 may have a backward-upward slope.

The upper side of the chamber body 361 has a downward slope toward the rear and the lower side has an upward slope toward the rear, so that the front end of the chamber body 360a has a larger cross-sectional area than the rear end.

Through this structure, there is an advantage of being able to easily insert the first collecting part 510 in a fixed form into the collecting part accommodating space 360a.

An air inlet 3621 may be provided in the chamber body 361 .

Air introduced through the first flow passage 381 passes through the air inlet 3621 . The air inlet 3621 may be provided on an upper surface of the chamber body 361 . Alternatively, the air inlet 3621 may be provided at an end of a hollow tube integrally connected to the chamber body 361 .

The air inlet 3621 is vertically overlapped with the dust inlet of the collecting unit 500 to be described later. That is, the air and dust passing through the first flow path 381 pass through the air inlet 3621 and the dust inlet in turn, and are introduced into the dust receiving space of the collecting unit 500 .

An inlet sealing member 367 may be disposed between the air inlet 3621 and the first flow path 381 . The inlet sealing member 367 seals between the air inlet 3621 and the first flow passage 381 to prevent air and dust from leaking into a space other than the chamber body 361 . The inlet sealing member 367 may be disposed in a form surrounding the circumference of the air inlet 3621 .

As described above, the chamber body 361 has an inclined structure that generally descends from the front upper end to the rear upper end, and an inclined surface formed with a backward-downward slope at a predetermined angle in a partial region of the upper surface of the chamber body 361. this may be included.

The air inlet 3621 formed on the upper part of the chamber body 361 may also be formed so that its open end face slopes downward from the front to the rear.

An air outlet 3622 may be provided in the chamber body 361 .

The air outlet 3622 passes the dust-filtered air passing through the collecting unit 500 . The air outlet 3622 may be provided under the chamber body 361 . The air outlet 3622 may be provided at the lower end of the mounting wall of the filter mounting portion 365 to be described later (see FIG. 15).

The air outlet 3622 is connected to the dust suction module 390. That is, the air passing through the air outlet 3622 may be finally discharged to the outside of the housing through the dust suction module 390 .

Referring to FIGS. 11 and 15 , the chamber unit 360 may include a compression driving unit 362 .

The compression drive unit 362 is a component that generates power to rotate the compression rotation unit 515 that compresses the dust collected in the first collection unit 510 . The compression rotation unit 515 will be described later.

The compression driving unit 362 may be disposed under the chamber body 361 . More specifically, the compression driver 362 may be disposed on the outer lower portion of the chamber body 361 .

A detailed configuration of the compression drive unit 362 will be described with further reference to FIG. 16 .

The compression drive unit 362 may include a compression motor 3622 . The compression motor 3622 may be disposed outside the collecting unit accommodating space 360a. That is, the compression motor 3622 may be disposed on the outer lower portion of the chamber body 361 .

The compression motor 3622 generates power for rotating the compression rotation unit 515 . The compression motor 3622 is provided as a motor capable of forward and reverse rotation. In other words, as the compression motor 3622, a motor capable of rotating in both directions is used.

In this way, in order to allow forward and reverse rotation of the compression motor 3622, a synchronous motor may be used as the compression motor 3622. Such a syncronos motor is configured to allow normal and reverse rotation by the motor itself, and when the force applied to the compression motor 3622 is greater than a set value when the compression motor 3622 rotates in one direction, the compression motor 3622 The rotation of is converted to the other direction.

At this time, the force applied to the compression motor 3622 is a resistance force (torque) generated as the rotary plate 5153 to be described later presses the dust, and when the resistance force reaches a set value, the compression motor 3622 rotates It is configured to change direction.

Since technologies for other synchronos motors are generally known in the field of motor technology, a detailed description thereof will be omitted.

The compression driving unit 362 may further include a driving gear 3621 .

The drive gear 3621 is rotated by the power of the compression motor 3622 . To this end, the driving gear 3621 may be connected to the motor shaft of the compression motor 3622. A driving gear 3621 may be coupled to the upper side of the compression motor 3622.

The driving gear 3621 may be disposed outside the collecting unit accommodating space 360a. That is, the driving gear 3621 may be disposed outside the chamber body 361 .

At this time, a portion of the lower surface of the chamber body 361 may protrude upward to form a driving gear accommodating portion 3623 (see FIG. 15).

A gear passage hole 3623a exposing at least a portion of the drive gear 3621 toward the inside of the collecting unit accommodating space 360a is formed in the lower portion of the chamber body 361 . More specifically, the gear passage hole 3623a may be formed by penetrating a side surface of the driving gear accommodating part 3623 . The gear teeth 3621c of the drive gear 3621 may be exposed through the gear passage hole 3623a (see FIG. 15).

On the other hand, since the driving gear 3621 and the compression motor 3622 are disposed outside the collecting unit accommodating space 360a, considering that the collecting unit accommodating space 360a is a space that is periodically opened, the driving gear 3621 and This has the effect of ensuring that the compression motor 3622 is not exposed to contamination.

The drive gear 3621 may transmit rotational power to the compression rotation unit 515 .

The compression rotating unit 515 is a concept including one or more components that rotate to compress the dust collected in the dust receiving space of the first collecting unit 510 .

Although a detailed structure will be described later, the rotation plate 5153 included in the compression rotation unit 515 rotates to collect dust. The rotating plate 5153 may pressurize and compress dust collected between the fixed plate 5152 and the fixed plate 5152 while rotating to be closer to the fixed plate 5152 fixedly disposed on one side of the first collecting unit 510 .

A transmission gear 514 may be included in the first collecting unit 510 .

The transmission gear 514 is coupled to the compression rotation unit 515 and may be disposed between the compression drive unit 362 and the compression rotation unit 515 to transmit rotational power.

More specifically, the transmission gear 514 may be disposed outside the lower part of the first collecting part 510 . When the first collecting part 510 is inserted into the collecting part accommodating space 360a, the gear teeth 5142 of the transmission gear 514, the gear teeth of the drive gear 3621 exposed by the gear passage hole 3623a (3621c) and can be geared to each other.

Thus, rotational power generated by the compression motor 3622 may be transmitted to the compression rotation unit 515 via the driving gear 3621 and the transmission gear 514 .

On the other hand, since the drive gear 3621 is accommodated in the drive gear accommodating portion 3623, and the drive gear accommodating portion 3623 is formed in a structure protruding upward from the lowermost surface of the collecting unit accommodating space 360a, the user can use the first The transmission gear 514 and the driving gear 3621 can be easily meshed with each other even by simply pushing the collecting unit 510 horizontally.

Referring to FIGS. 14 and 15 , the chamber unit 360 may include a rail unit 363 .

The rail unit 363 may be disposed above the chamber body 361 . More specifically, the rail unit 363 may be disposed on an inner upper portion of the chamber body 361 .

The rail part 363 has a structure in which at least a part of the second collecting part 520 is fitted, and the second collecting part 520 can slide along the rail part 363 . The second collecting unit 520 may be supported while being spaced apart from the lower surface of the chamber body 361 and hanging from the rail unit 363 .

As described above, the second collecting unit 520 is an envelope-type collecting unit 500 in which the shape of the dust accommodating space is variable.

At this time, the dust bag 521 included in the second collecting unit 520 is inflated by the suction drive of the dust collecting motor 391, and the negative pressure formed as the dust bag 521 expands from the first flow path 381. Dust may flow into the dust bag 521 .

In the embodiment of the present invention, the dust bag 521, which is one component of the second collecting unit 520, is made of a breathable material. That is, dust of a certain size or more cannot escape, but is made of a material that allows air to escape. Therefore, as long as the suction drive of the dust collection motor 391 continues, the suction of dust into the dust bag 521 continues.

When the dust bag 521 is maximally inflated and there is no separation distance between the lowermost end of the dust bag 521 and the inner lower surface of the chamber body 361, the dust suction power is reduced. Therefore, it is preferable that the dust bag 521 is spaced apart from the lower surface of the chamber body 361 by a predetermined distance even in a maximum inflated state so that the suction power can be evenly transmitted to the dust bag 521 .

In the embodiment of the present invention, the rail part 363 having a structure that supports the second collecting part 520 by separating it from the lower surface of the chamber body 361 is provided, so that the first collecting part 510 and the second collecting part Compatibility between (520) becomes possible.

The rail unit 363 may include a rail body 3631 .

Referring to FIGS. 13 to 15 , the rail body 3631 may form a space in which the second collecting unit 520 slides. The rail body 3631 may be formed to extend from the front to the rear of the chamber body 361 . The rail body 3631 may be disposed on the left and right sides, respectively. The rail body 3631 may be formed in a left-right symmetrical structure.

The rail body 3631 is open toward the center of the chamber body 361 and may be provided in a shape similar to a 'U' rotated 90 degrees. From another point of view, the rail body 3631 may be provided in a shape similar to the Korean consonant 'c' based on the rail body 3631 disposed on the left side.

However, the shape of the rail body 3631 described above is an example, and the shape of the rail body 3631 may be changed to an appropriate structure capable of supporting the second collecting unit 520 on the upper side of the chamber body 361.

The upper surface of the rail body 3631 disposed on the upper surface of the chamber body 361 may be configured as an inclined surface similar to the upper surface of the chamber body 361 . Alternatively, the lower surface of the rail body 3631 may be formed parallel to the ground (see FIG. 13).

Hereinafter, a detailed configuration of the rail unit 363 will be further described with reference to FIGS. 17 and 18 .

Fig. 17 is an enlarged view of section "A" in Fig. 15, and Fig. 18 is a sectional view taken along line C-C' in Fig. 17.

Referring to FIGS. 17 and 18 together with FIG. 15 , the rail unit 363 may further include an interference protrusion 3632 .

The interference protrusion 3632 may be disposed at a first position (Position 1) in front of the rail body 3631 to interfere with the housing cover 370.

More specifically, the first position may mean a position preventing the housing cover 370 from closing one open side of the chamber body 361 .

From another point of view, the first position is when the first collecting part 510 or the second collecting part 520 is inserted into the collecting part accommodating space 360a, the first collecting part 510 and the second collecting part 520 ) It may mean a position that shields the insertion progress path of some components included in.

Here, the partial component for shielding the insertion path may be an external plate 522 to be described later in the case of the first collecting unit 510 (see FIG. 31). In the case of the second collecting unit 520, the part The configuration may be a rib 5161c protruding from the collecting unit cover 516 (see FIG. 23).

The interference protrusion 3632 is formed by contact with the first collecting part 510 (specifically, the outer plate 522) or the second collecting part 520 (specifically, the rib 5161c). 370) may be moved to a second position (Position 2) where interference is avoided.

Meanwhile, a cover protrusion 371 may protrude from the housing cover 370 .

The cover protrusion 371 may be disposed at a position in contact with the aforementioned interference protrusion 3632 when the housing cover 370 rotates to close the opened side of the chamber body 361. (FIG. 15) That is, the meaning that the interference protrusion 3632 interferes with the housing cover 370 means that the interference protrusion 3632 and the cover protrusion 371 contact each other.

The rail unit 363 may further include a protrusion guide 3633 .

Continuing to refer to FIGS. 17 and 18 , the protrusion guide 3633 may be combined with the interference protrusion 3632 . The protrusion guide 3633 may guide the movement of the interference protrusion 3632 .

More specifically, the protrusion guide 3633 has a space in which the interference protrusion 3632 is accommodated, and a hook 3632a formed at an end of the interference protrusion 3632 is engaged with a locking jaw inside the space. (3662) may be formed.

The interference protrusion 3632 may be disposed at the first position in a state in which the hook 3632a and the locking protrusion 3662 are in contact with each other. As the interference protrusion 3632 moves from the first position to the second position, contact between the hook 3632a and the locking jaw 3662 may be released (see FIG. 19 ).

The rail unit 363 may further include a restoring member 3634.

Referring to FIG. 18 , a restoring member 3634 may be coupled to a space formed inside an interference protrusion 3632 . A direction in which the interference protrusion 3632 moves from the first position to the second position is defined as a first movement direction md1, and a direction opposite to the first movement direction is defined as a second movement direction md2. The restoring member 3634 may provide elastic force toward the second moving direction to the interference protrusion 3632, and the hook 3632a and the locking jaw 3662 contact the interference protrusion 3632 by the restoring member 3634. may be moved in the second movement direction until

Referring to FIG. 19 , the operation of the interference protrusion 3632 when the collecting unit 500 is inserted into the collecting unit accommodating space 360a and when it is not inserted will be described.

19 is a diagram for explaining the movement of the interference protrusion 3632 and its positional relationship with the housing cover 370 according to the embodiment of the present invention.

The left view of FIG. 19 shows a case where the interference protrusion 3632 is in the first position and the cover protrusion 371 and the interference protrusion 3632 are in contact. At this time, as the cover protrusion 371 contacts the interference protrusion 3632, the direction in which force is applied to the interference protrusion 3632 and the direction in which the interference protrusion 3632 is moved from the first position to the second position are at a predetermined angle. can achieve

The force does not have a component in a direction that moves the interference protrusion 3632 from the first position to the second position. Therefore, the movement of the interference protrusion 3632 cannot be achieved by the force pressed by the cover protrusion 371, and the interference protrusion 3632 prevents the housing cover 370 from rotating any further, so that the chamber body 361 is cannot be closed.

In the drawing on the right of FIG. 19 , the interference protrusion 3632 is in the second position, and the cover protrusion 371 does not contact the interference protrusion 3632 . The housing cover 370 may rotate and move until one side of the chamber body 361 is completely closed.

At this time, it is the first collecting part 510 or the second collecting part 520 that moves the interference protrusion 3632 from the first position to the second position. When the first collecting part 510 or the second collecting part 520 is inserted into the collecting part accommodating space 360a, a part 5162a of the first collecting part 510 or the second collecting part 520 is The interference protrusion 3632 may be pushed to the second position.

The interference protrusion 3632 may be provided with an inclined portion 3632c that comes into contact with some components of the collecting unit 500 .

Referring to FIG. 15 , the chamber unit 360 may further include a filter mounting unit 365 .

The filter mounting part 365 may be disposed under the chamber body 361 . The filter mounting unit 365 may include a filter mounting space to which the pre-filter module 470 for filtering the air passing through the collecting unit 500 is detachably coupled and a mounting wall surrounding the filter mounting space.

At this time, the air outlet 3622 described above is formed at the lower end of the mounting wall. From another point of view, the air outlet 3622 is formed at the lower end of the filter mounting space.

When the pre-filter module 470 is coupled to the filter mounting part 365, the air exiting the collecting unit 500 and heading for the air outlet 3622 passes through the pre-filter module 470 and passes through the air outlet 3622. It moves to the dust suction module 390 through the .

If the pre-filter module 470 is not coupled to the filter mounting part 365, the air exiting the collecting part 500 passes through the air outlet 3622 as it is and moves to the dust suction module 390.

20 is a diagram in which the pre-filter module 470 is divided into constituent units and developed according to an embodiment of the present invention.

Referring to FIG. 20 , a pre-filter module 470 may include filter cases 471 and 472 and filters 473 and 474 .

The filter cases 471 and 472 may include an upper case 471 and a lower case 472, and the upper case 471 and the lower case 472 may be coupled through a hinge. When the hinge is rotated as an axis, the space inside the case can be opened and closed.

An air inlet 4711 is formed in the upper part of the case 471 .

The air inlet 4711 may be formed on the upper surface of the upper case 471 in a shape corresponding to the shape of the collecting unit passage 518 of the first collecting unit 510 to be described later. Air exiting the collecting unit passage 518 of the first collecting unit 510 may be introduced into the filter cases 471 and 472 through the air inlet 4711 . Air exiting the dust bag 521 of the second collecting unit 520 may be introduced into the filter cases 471 and 472 through the air inlet 4711 .

An air outlet 4721 is formed in the lower part of the case 472 .

The air outlet 4721 may be formed of a plurality of holes penetrating the lower surface of the lower case 472 . The air outlets 4721 may be disposed to be distributed over the entire lower surface of the lower case 472 so that air can pass through the filter evenly.

At least one or more filters 473 and 474 may be accommodated in the inner space formed by the upper case 471 and the lower case 472 . The filters 473 and 474 may include a first filter 473 made of a sponge material. The filters 473 and 474 may include a second filter 474 made of non-woven fabric.

A pressing protrusion 4712 may protrude from one side of the filter cases 471 and 472 .

The pressing protrusion 4712 presses the filter sensing protrusion 366 to be described later when the pre-filter module 470 is mounted on the filter mounting portion 365. The pressing protrusion 4712 may be formed in the form of a rib protruding from one surface of the upper case 471 or the lower case 472 (see FIG. 22).

Referring to FIG. 15 , the chamber unit 360 may further include a filter sensing protrusion 366 .

The filter sensing protrusion 366 may be disposed below the chamber body 361 . More specifically, the filter sensing protrusion 366 may be disposed adjacent to a mounting wall of the filter mounting portion 365 .

One side of the filter sensing protrusion 366 may maintain a protruding state toward the collecting unit accommodating space 360a in a state in which the pre-filter module 470 is not coupled to the filter mounting unit 365 .

To this end, although not shown, a pressing means for applying force in a direction in which the one side protrudes may be coupled to the filter sensing protrusion 366 . For example, the pressing means may be an elastic body such as a spring.

As such, when one side of the filter sensing protrusion 366 protrudes toward the collecting unit accommodating space 360a, the rear side of the first collecting unit 510 and the filter sensing protrusion 366 are interfered with, and the first collecting unit 510 is interfered with. It becomes impossible to completely insert the 510 into the collecting unit accommodating space 360a.

On the other hand, since the second collecting unit 520 remains spaced apart from the lower end of the chamber body 361 even when the dust bag 521 is fully inflated, the second collecting unit ( 520) is not hindered.

Through this configuration, the user cannot use the first collecting unit 510 without mounting the pre-filter module 470 on the filter mounting unit 365 . If the user inserts the first collecting part 510 into the chamber body 361 while forgetting to separate the pre-filter module 470, it will be caught by the filter sensing protrusion 366 and not completely inserted. The user may insert the first collecting part 510 into the chamber body 361 again after mounting the pre-filter module 470 on the filter mounting part 365 .

Meanwhile, in a state in which the pre-filter module 470 is coupled to the filter mounting portion 365, one side of the filter sensing protrusion 366 may be pressed by the pre-filter module 470. At this time, the filter sensing protrusion 366 may be moved in a direction to avoid interference with the first collecting unit 510 .

FIG. 21 is an enlarged view of part “B” of FIG. 15 and is a view for explaining the movement of the filter sensing protrusion 366 depending on whether the pre-filter module 470 is mounted, and FIG. 22 is D-D of FIG. 21 ' It's a cross section.

Referring to FIGS. 21 and 22 , the filter sensing protrusion 366 may include a protrusion body 3661 and a locking protrusion 3662 protruding from an outer surface of the protrusion body 3661 . At this time, a space in which the above-described pressing means (not shown) is disposed may be formed inside the protruding body 3661 .

The left view of FIG. 21 shows a state in which the pre-filter module 470 is not mounted on the filter mounting part 365. The filter sensing protrusion 366 maintains a state in which one side protrudes toward the collecting unit accommodating space 360a.

The right side view of FIG. 21 shows a state in which the pre-filter module 470 is mounted on the filter mounting part 365. Referring to FIG. 22 , the holding jaw 3662 of the filter sensing protrusion 366 is pressed by the pressing protrusion 4712 .

At this time, as in the embodiment of FIG. 22 , the pressing protrusion 4712 may protrude from one surface of the upper case 471 . As the pre-filter module 470 is mounted on the filter mounting portion 365, the pressing protrusion 4712 may come into contact with the locking protrusion 3662, and the filter sensing protrusion protrudes by invading the collecting unit accommodating space 360a. One side of (366) can be pressed downward.

Thus, the first collecting part 510 can be completely inserted into the chamber body 361 without interference.

Meanwhile, the need for the above-described filter sensing protrusion 366 is related to the fact that the dust separating means between the first collecting unit 510 and the second collecting unit 520 are different.

The dust separating means of the first collecting unit 510 may include a mesh network 5121 and a cyclone 513 .

A dust bag 521 made of a breathable material may be included as a dust separating means of the second collecting unit 520 .

In the case of the second collecting unit 520, dust larger than a certain size cannot pass through the dust bag 521 structurally. Since the dust bag 521 itself can perform a function of a pre-filter, the installation of the pre-filter module 470 is a user's choice and is not essential.

However, in the case of the first collecting unit 510, although it is possible to generally separate even fine dust through the dust collecting action of the cyclone 513, it is structurally fine like the dust bag 521 of the first collecting unit 510. It is impossible to completely filter the dust.

Therefore, in order to prevent fine dust from entering the dust collecting motor 391, the pre-filter module 470 must be disposed in the path through which the air passing through the first collecting unit 510 flows into the dust collecting motor 391. do.

The embodiment of the present invention has an effect of calling the user's attention to the non-mounting of the pre-filter module 470 when the first collecting unit 510 is used.

In addition, in the embodiment of the present invention, the use of the second collecting unit 520 is possible regardless of whether the pre-filter module 470 is mounted, so that the cost of purchasing a filter can be reduced according to the user's selection.

Referring to FIG. 13 , the chamber unit 360 may further include a sterilization module mounting unit 364.

The sterilization module mounting portion 364 may be disposed above the chamber body 361 . The sterilization module mounting portion 364 may be disposed spaced apart from the air inlet 3621. The sterilization module mounting portion 364 may include a sterilization module mounting space formed by bending a portion of the upper surface of the chamber body 361 upward and a mounting wall surrounding the mounting space.

A sterilization module 450 may be mounted on the sterilization module mounting unit 364 to irradiate ultraviolet light toward the collecting unit accommodating space 360a.

The sterilization module 450 is a component provided to sterilize dust collected in the collecting unit 500 . The sterilization module 450 may include a light source for emitting sterilization light and a protective panel disposed under the light source to protect the light source.

In a possible embodiment, the light source and the protection panel may be mounted on the sterilization module mounting part 364 in a form accommodated in a separately provided housing. Alternatively, in a possible embodiment, the light source and the protection panel may be mounted in the sterilization module mounting space in a form directly accommodated in the sterilization module mounting space.

As such, the combined form of the sterilization module 450 and the sterilization module mounting portion 364 is any one of the arrangements as long as the light source of the sterilization module 450 is disposed so as to emit sterilization light toward the collecting unit receiving space 360a. It is not limited to the examples.

Here, the light source may include at least one light emitting diode (LED) capable of emitting sterilizing light having sterilizing power capable of removing bacteria. The sterilization light emitted by the light source may have a wavelength that varies depending on the type of light emitting diode.

For example, the light source may be a light emitting diode that emits ultraviolet light having a UV-C wavelength range. Ultraviolet rays are divided into UV-A (315nm ~ 400nm), UV-B (280nm ~ 315nm), and UV-C (200nm ~ 280nm) according to the wavelength. can inhibit the growth of microorganisms.

Alternatively, as another example, the light source may be a light emitting diode emitting visible light having a wavelength of 405 nm. Blue light having a wavelength of 405 nm has a wavelength in the boundary region of visible light and ultraviolet light, and its sterilizing power has been proven.

The protection panel may be spaced apart from the light source by a predetermined distance to prevent damage to the light source. At this time, the protection panel may be provided with a material that maximizes the transmittance of the light source. For example, the protection panel may be made of quartz. It is known that quartz does not interfere with the transmission of ultraviolet light in the UV-C region.

In the embodiment of the present invention, by providing the sterilization module 450 and the sterilization module mount 364, even when the dust sucked from the dust bin 220 of the first cleaner 200 is stored in the collecting unit 500 for a long time, the cleaner There is an advantage in that the station 300 can be managed hygienically.

In addition, in the embodiment of the present invention, since the sterilization module mounting part 364 is disposed in the chamber part 360, there is an advantage that the user can use the sterilization function regardless of which type of collecting part 500 is selected.

Hereinafter, a detailed structure of the first collecting unit 510 will be described.

23 is a perspective view of the first collecting unit 510 in an embodiment of the present invention, and FIG. 24 is a perspective view of the first collecting unit 510 in an embodiment of the present invention, separated and developed. FIG. 25 is a diagram showing a dust separation process of the cyclone 513 in an embodiment of the present invention, and FIG. 26 is a XX' cross-sectional view of FIG. 23 .

Referring to FIGS. 23 to 26 , the first collecting part 510 may include a collecting part body 511 and an inner wall 512 of the collecting part.

The collector body 511 forms the exterior of the dust receiving space. In a possible embodiment, the collector body 511 may be in the form of a generally hexahedron. In another possible embodiment, the collector body 511 may be of a generally cylindrical shape.

Dust may be collected in the inner space of the collector body 511 .

The first collecting unit 510 may further include a collecting unit cover 516 provided to cover the open upper side of the collecting unit body 511 . That is, the collecting unit cover 516 may be coupled to the upper side of the collecting unit body 511 and covers the open upper side of the collecting unit body 511 so that air can flow therein and a space in which dust is stored. can form

The shape of the collecting part cover 516 may be formed to correspond to the shape of the rail part 363 .

More specifically, the collecting unit cover 516 may include a first cover unit 5161 and a second cover unit 5162 .

An upper surface of the first cover part 5161 may be formed as an inclined surface having a backward-downward slope. Thus, the rear of the first collecting unit 510 may be formed with a low height to the top and a high front to the top.

Meanwhile, as described above, the collecting part accommodating space 360a formed by the chamber body 361 may have a cross-sectional area of a front end larger than a cross-sectional area of a rear end.

That is, the rear of the first collecting part 510, where the insertion into the collecting part accommodating space 360a starts, has a low height, and the front end of the collecting part accommodating space 360a, which is an entrance into which the first collecting part 510 is inserted, is Since the height is high, the first collecting part 510 can be easily inserted into the collecting part accommodating space 360a.

The second cover part 5162 may be connected to both left and right sides of the first cover part 5161 . The second cover part 5162 may be formed to extend horizontally from the lower end of the side surface of the first cover part 5161 . That is, the top surface of the first cover part 5161 and the top surface of the second cover part 5162 may form a step so that the top surface of the first cover part 5161 is at a higher position.

In a state where the first collecting part 510 is inserted into the chamber body 361, the side surface of the first cover part 5161 is disposed to face the side surface of the rail body 3631. More specifically, the left and right side surfaces of the first cover portion 5161 are disposed to face the side surfaces of the left and right rail bodies 3631. From another point of view, the first cover part 5161 is disposed between the left and right rail bodies 3631 (see FIG. 29).

In a state where the first collecting part 510 is inserted into the chamber body 361, the upper surface of the second cover part 5162 is disposed to face the lower surface of the rail body 3631.

A transparent panel 5161b may be disposed on the upper surface of the first cover part 5161 .

When the first collecting part 510 is inserted into the chamber body 361, the transmission panel 5161b is disposed at a position corresponding to the position at which the sterilization module 450 is disposed. That is, when the first collecting unit 510 is inserted into the chamber body 361, the sterilization module 450 and the transmission panel 5161b are disposed to face each other.

The transmission panel 5161b may be made of a material through which light is transmitted. Specifically, the transmission panel 5161b is made of a material through which sterilization light emitted from the sterilization module 450 can be transmitted toward the inside of the collector body 511 . For example, the transmission panel 5161b may be made of a poly methyl methacrylate (PMMA) material.

The transmission panel 5161b may include an inclined surface 5161ba disposed at a predetermined angle with the ground. That is, the transparent panel 5161b may include an inclined surface 5161ba forming a predetermined angle with respect to the top surface of the first cover part 5161 . For example, as shown in FIG. 30 , the inclined surface 5161ba may be formed to be inclined downward in the first cover part 5161 .

With this configuration, the sterilization light (ultraviolet ray) irradiated from the sterilization module 450 can change the refraction angle while passing through the inclined surface 5161ba of the transmission panel 5161b, and as a result, irradiation of the sterilization light in the collecting unit 500 area can be expanded.

A dust inlet 5161a through which air and dust are introduced from the first flow path 381 may be formed on an upper surface of the first cover part 5161 . For example, the dust inlet 5161a may have a circular shape. A first flow path 381 is connected to the upper side of the dust inlet 5161a. As a result, air sucked by the suction force of the dust collecting motor 391 may flow into the collector body 511 . The dust inlet 5161a may be disposed above a first dust accommodating space S1 to be described later.

With this configuration, air may be introduced from the upper side of the collecting unit 500 through the dust inlet 5161a. That is, the dust inlet 5161a communicates with the first flow path 381, and when the dust collecting motor 391 is operated, air may flow into the collecting unit 500 along a direction perpendicular to the ground. Therefore, according to the present invention, there is an effect of minimizing passage loss.

In addition, the dust inlet 5161a communicates with the third flow path 383, and when the dust collecting motor 391 is operated, the dust stored in the dust container 110 of the second cleaner 100 disposed below the dust collecting motor 391 can be introduced from the upper side. At this time, the dust inlet 5161a may be in communication with the third flow path 383 through the first flow path 381, and the first flow path 381 or the third flow path through the flow path conversion module 384 according to an embodiment. It is also possible that 383 is optionally connected.

With this configuration, compared to the case where the dust inlet is formed on the side of the collecting unit, there is an effect of preventing dust included in the air from flowing backward.

In addition, even when the collecting unit 500 communicates with the dust bin 220 of the first vacuum cleaner or the dust bin 110 of the second vacuum cleaner, the suction power of the dust collecting motor 391 is lost by unifying the air inlet space into one. It has the effect of enabling sufficient delivery without being

Based on the state in which the first collecting part 510 is inserted into the chamber body 361, the dust inlet 5161a and the air inlet 3621 of the chamber body 361 may be positioned to face each other.

At this time, since the dust inlet 5161a is formed on the upper surface of the first cover part 5161 having a backward-downward slope, the cross section of the dust inlet 5161a also has a backward-downward slope. Previously, it has been described that the cross section of the air inlet 3621 also has a backward-downward slope. Since the air inlet 3621 and the dust inlet 5161a have an inclination in the same direction, they can be sealed without separation from each other.

The first collecting unit 510 may include an inlet cover 5163 . The inlet cover 5163 may be rotatably coupled to the collector cover 516 . Specifically, the inlet cover 5163 may be hinged to the first cover part 5161 .

The inlet cover 5163 may open and close the dust inlet 5161a. The inlet cover 5163 is configured to close or open the dust inlet 5161a, and may be provided in a shape corresponding to that of the dust inlet 5161a and coupled to one side of the dust inlet 5161a.

The inlet cover 5163 may be opened by the suction force of the dust collecting motor 391 . That is, the inlet cover 5163 may be opened toward the inner space (specifically, the first dust accommodating space S1) of the collector body 511 .

At this time, in a state in which the dust collection motor 391 is operated, the imaginary plane P extending the inlet cover 5163 may pass through the mesh 5121 (see FIG. 30 ).

With this configuration, air passing through the dust inlet 5161a may flow downwardly toward the mesh 5121 along the surface of the inlet cover 5163 . Therefore, the flow direction of the air passing through the dust inlet 5161a may be guided toward the mesh 5121 .

The inlet cover 5163 may keep the dust inlet 5161a closed when the dust collecting motor 391 is not driven, and open the dust inlet 5161a when the dust collecting motor 391 starts to operate.

To this end, a means for applying a restoring force in a direction of closing the dust inlet 5161a may be provided in the inlet cover 5163 . The restoring force applying means may be, for example, an elastic member such as an x-torsion spring.

Through this configuration, the inlet cover 5163 maintains a state in which the dust inlet 5161a is always closed in a state in which suction force is not applied, and odor, contamination, bacteria, etc. that may occur inside the first collecting unit 510 It is prevented from spreading to the first flow path 381 .

A rib 5161c may protrude from an outer surface of the first cover part 5161 .

Here, the outer surface may refer to a surface connecting the upper surface of the first cover part 5161 and the upper surface of the second cover part 5162 .

The rib 5161c may be formed in front of the outer surface of the first cover part 5161 . The rib may protrude in a direction parallel to the upper surface of the second cover part 5162 . The rib 5161c may be inserted into the sliding space of the rail part 363 (specifically, the rail body 3631) as the first collecting part 510 is inserted into the chamber body 361.

As the first collecting part 510 is inserted into the chamber body 361, the rib 5161c may push the interference protrusion 3632 disposed in the first position to the second position (see FIG. 19).

The first collecting part 510 includes a guide wall 5161d. The guide wall 5161d may protrude from the lower surface of the collecting unit cover 516 . Specifically, the guide wall 5161d may protrude and extend downward from the lower side of the first cover part 5161 . In this case, a pair of guide walls 5161d may be formed facing each other with the dust inlet 5161a interposed therebetween.

Accordingly, the guide walls 5161d are disposed on both sides of the dust inlet 5161a to prevent air introduced through the dust inlet 5161a from flowing in the direction in which the guide wall 5161d is formed.

At least a portion of the guide wall 5161d may be formed along a direction perpendicular to the rotational axis Y of the inlet cover 5163 (see FIG. 31 ).

Therefore, when the inlet cover 5163 is opened with the rotating shaft of the inlet cover 5163 as the center of rotation, the air introduced through the dust inlet 5161a passes through the pair of guide walls 5161d and the inlet cover 5163 to 3 The flow is restricted in one direction and the flow can be guided towards the other open direction.

As a result, the flow direction of the air introduced through the dust inlet 5161a may be guided toward the mesh network 5121 by the guide wall 5161d and the inlet cover 5163.

Meanwhile, as shown in FIG. 31 , according to an embodiment, a part of the guide wall 5161d may be formed in a bent shape toward the rotational axis of the inlet cover 5163 . With this configuration, a space between the guide wall 5161d and the open inlet cover 5163 can be reduced, and air guiding efficiency can be improved.

Therefore, according to the present invention, the guide wall 5161d and the inlet cover 5163 guide the flow path of the air introduced into the collecting unit 500 as short as possible, thereby optimizing the air flow efficiency.

The first collecting unit 510 may further include a lower cover 517 provided to cover the opened lower side of the body of the first collecting unit 510 .

A collecting unit hinge 519 may be disposed at one corner of the lower cover 517 . When the lower cover 517 rotates around the collector hinge 519, the inside of the collector body 511 may be opened. Thus, the user can remove the dust collected in the collector body 511 by discharging it to the outside.

A handle 5111b may be disposed on the front (or front side) of the collector body 511 . The handle 5111b is configured to be gripped by a user so that the first collecting part 510 can be drawn out of the chamber body 361 . The user can easily take out the first collecting part 510 from the chamber body 361 by holding the handle 5111b and pulling the first collecting part 510 forward.

A finger groove 5111a may be provided in the collecting unit body 511 so that a user can easily grip the handle 5111b. The finger groove 5111a is formed as a groove that can fit a user's finger. The finger groove 5111a is formed in a shape where the collecting part body 511 is recessed toward the inner space of the first collecting part 510 .

Through this configuration, the handle 5111b does not excessively protrude outward from the collecting unit body 511 . That is, through this configuration, the cleaner station 300 may be reduced in size.

The inner wall 512 of the collector may be disposed inside the dust accommodating space of the collector body 511 . The inner wall 512 of the collecting unit may divide the dust receiving space of the collecting unit body 511 into two separate spaces. The collecting unit inner wall 512 may be disposed in a direction perpendicular to the ground. With this configuration, the collecting unit inner wall 512 is provided to be detachable and coupled in a vertical direction in relation to the collecting unit body 511, so that the user can easily separate and clean it.

A mesh network 5121 may be provided on the inner wall 512 of the collecting unit. For example, the mesh network 5121 may form part of the inner wall 512 of the collecting unit. That is, when air flows from one side of the divided dust accommodating space to the other side, it may pass through the mesh network 5121 .

The mesh network 5161a may filter dust from air introduced through the dust inlet 5161a. That is, the mesh network 5161a may be a means capable of separating dust from the air introduced into the first collecting unit 510 .

Therefore, hereinafter, it may be referred to as dust separators 5121 and 513 including a mesh network 5161a and a cyclone 513 to be described later.

The dust separators 5121 and 513 are disposed inside the collector body 511 and may separate dust from air introduced through the dust inlet 5161a.

Meanwhile, the receiving space inside the first collecting unit 510 is divided into a first dust receiving space S1 and a second dust receiving space S2 by the inner wall 512 of the collecting unit.

A compression rotation unit 515 may be disposed in the first dust accommodating space S1. A cyclone 513 may be disposed in the second dust accommodating space S2. Air sucked from the outside through the first flow path 381 first flows into the first dust receiving space S1 and passes through the mesh 5121 to flow into the second dust receiving space S2.

Through this, relatively large dust may be filtered through the mesh network 5121. The filtered large dust is collected and stored on the lower side of the first dust accommodating space S1.

In this embodiment, the dust separator includes a cyclone 513.

A plurality of cyclones 513 may be provided. For example, at least two or more cyclone bodies having a conical or cylindrical shape may be provided.

At this time, the cyclone 513 may be disposed along a direction perpendicular to the ground. With this configuration, the cyclone 513 is provided to be detachable and coupled in a vertical direction in relation to the collector body 511, so that the user can easily separate and clean the cyclone 513.

The cyclone 513 may separate dust from air passing through the mesh 5121 .

Here, the cyclone 513 may be disposed between the mesh network 5121 and the collector passage 518 .

Through such an arrangement, a path through which air flows within the collecting unit 500 may be optimized.

Referring to FIG. 25 , each cyclone body includes an inlet body 5131 disposed to allow air passing through the mesh 5121 to be introduced. Each cyclone body further includes an outflow body 5132 connected to the collecting unit passage 518 .

The collecting unit passage 518 is disposed inside the collecting unit body 511 and may guide air passing through the dust separators 5121 and 513 to the dust collecting motor 391 .

In addition, the collector flow path 518 is a flow path connected to the dust collecting motor 391 side, and is a flow path constituting a part of the second flow path 382 as described above.

The collecting unit passage 518 may be formed along a direction perpendicular to the ground. Accordingly, air may flow in a direction perpendicular to the ground through the collecting unit passage 518 .

Air is sucked in from the outflow body 5132 by the suction force applied to the collector passage 518, and a cyclone flow is generated in the inflow body 5131. Due to this cyclone flow, fine-sized dust may be filtered from the air passing through the mesh 5121 .

The first collecting unit 510 may include a compression rotating unit 515 .

The compression rotating unit 515 is a component provided to compress dust collected in the first collecting unit 510 .

Referring to FIGS. 24 and 26 , the compression rotating unit 515 is disposed inside the dust receiving space of the collecting unit body 511 . More specifically, the compression rotation unit 515 is disposed inside the first accommodating space S1 of the collecting unit body 511 .

The compression rotation unit 515 is disposed to be movable inside the collecting unit body 511 . The compression rotation unit 515 may move in a direction of compressing the dust collected in the first dust accommodating space S1. In the embodiment of the present invention, the compression rotation unit 515 may be rotatably disposed in the first dust receiving space S1.

At least a portion of the compression rotation unit 515 may be disposed below the inlet cover 5163 . For example, the rotating shaft member 5151 may be disposed below the inlet cover 5163.

The compression rotation unit 515 may rotate around one axis disposed in the longitudinal direction in the interior of the collector body 511 (the first dust accommodating space S1). More specifically, the compression rotating unit 515 may include a rotating shaft member 5151 , a fixed plate 5152 and a rotating plate 5153 .

The rotating shaft member 5151 may be vertically disposed inside the collector body 511 , that is, in the first dust accommodating space S1 . The rotating shaft member 5151 may be rotated by receiving power from the compression motor 3622 described above. The central axis of the rotating shaft member 5151 may be coaxial with the central axis of the first dust accommodating space S1.

With this configuration, the compression rotation unit 515 is provided to be detachable and coupled in a vertical direction in relation to the collecting unit body 511, so that the user can easily separate and clean it.

A lower end of the rotating shaft member 5151 may be connected to and supported by a bottom surface of the first dust accommodating space S1. The upper end of the rotating shaft member 5151 may be spaced apart from the dust inlet 5161a by a predetermined distance so as not to interfere with the opening of the inlet cover 5163 (see FIG. 30).

The fixing plate 5152 may be fixedly disposed on one side inside the first collecting unit 510 . More specifically, the fixing plate 5152 may be vertically disposed in the first dust accommodating space S1 and fixedly coupled to one side of the inner circumferential surface of the collector body 511 forming the first dust accommodating space S1. The fixing plate 5152 may have a square flat plate shape. The fixing plate 5152 may be disposed on the opposite side of the mesh network 5121.

The fixing plate 5152 may completely or partially cover the first dust accommodating space S1 to compress dust pushed and moved by the rotation of the rotary plate 5153 together with the rotary plate 5153 .

The rotation plate 5153 is connected to the outer circumferential surface of the rotation shaft member 5151 and can rotate together with the rotation shaft member 5151 . More specifically, the rotating plate 5153 may be disposed between the inner circumferential surface of the collecting unit body 511 and the outer circumferential surface of the rotating shaft member 5151 constituting the first dust accommodating space S1 and may rotate.

The shape of the rotating plate 5153 is basically a square flat plate shape, but may be modified to avoid interference with other components disposed in the first dust accommodating space S1. For example, when the inlet cover 5163 opens the dust inlet 5161a, a cutout may be formed at an upper end of the rotation plate 5153 so as not to interfere with the rotation radius of the inlet cover 5163 (see FIG. 30 ). )

Specifically, the upper end of the rotation plate 5153 may be disposed farther from the ground than the upper end of the rotation shaft member 5151 . Accordingly, the distance from the rotating shaft of the inlet cover 5163 to the rotating plate 5153 may be greater than the diameter of the inlet cover 5163.

With this configuration, even if the inlet cover 5163 rotates, it is possible to avoid coming into contact with the compression rotation unit 515. That is, according to the present invention, interference between the inlet cover 5163 and the compression rotation unit 515 can be prevented.

The rotary plate 5153 can rotate in both forward and reverse directions. Based on a state in which the first dust accommodating space S1 is viewed from above (ie, a state in which the first collecting unit 510 is viewed from above), clockwise rotation is defined as forward rotation and counterclockwise rotation is defined as reverse rotation. can

As the rotating plate 5153 rotates, it may come into contact with the dust collected inside the collector body 511 and move the dust.

When the rotary plate 5153 rotates in the forward direction, one surface of the rotary plate 5153 and one surface of the fixed plate 5152 meet to compress dust. Likewise, when the rotary plate 5153 rotates in the reverse direction, the other surface of the rotary plate 5153 and the other surface of the fixing plate 5152 meet to compress dust. That is, some of the compressed dust exists near one surface of the fixing plate 5152, and the rest exists near the other surface of the fixing plate 5152.

The compression rotating unit 515 may further include a cleaning member 5154 .

Referring to FIGS. 24 and 26 , a cleaning member 5154 is coupled to an end of a rotating plate 5153 on the opposite side where the rotating shaft member 5151 is disposed. That is, one end of the rotary plate 5153 is coupled to the rotary shaft member 5151 and the other end is coupled to the cleaning member 5154 .

The cleaning member 5154 may be provided to rotate together with the rotating plate 5153 while coming into contact with the mesh 5121 . More specifically, one edge of the cleaning member 5154 may be disposed to contact one surface of the mesh network 5121 .

Through this, when the cleaning member 5154 rotates together with the rotating plate 5153, it can rotate while scratching the mesh 5121, and foreign substances adhering to the mesh 5121 can be removed. The cleaning member 5154 may be, for example, a rubber scrubber.

Therefore, according to the present invention, it is possible to compress the dust by rotating the compression rotating unit 515, and it is possible to increase the capacitance capable of being collected in the first collecting unit 510.

Meanwhile, as described above, the first collecting unit 510 may include a transmission gear 514 .

The transmission gear 514 may be coupled to the lower cover 517 of the first collecting unit 510 . When the first collecting part 510 is inserted into the collecting part accommodating space 360a, the transmission gear 514 and the driving gear 3621 may be engaged with each other, and the rotational power of the compression motor 3622 is the driving gear ( 3621) and the transmission gear 514 may be transmitted to the compression rotation unit 515.

Together with FIG. 24 , the transmission gear 514 and the drive gear 3621 will be described in detail with reference to FIGS. 27 and 28 .

27 is an enlarged view of the driving gear 3621 and the transmission gear 514 in the embodiment of the present invention, and FIG. 28 is a perspective view of the driving gear 3621 viewed from the bottom in the embodiment of the present invention. to be.

The transmission gear 514 may be connected to the rotation shaft member 5151 of the compression rotation unit 515 . Gear teeth 5142 engaged with the drive gear 3621 are disposed on the outer circumference of the lower portion of the transmission gear 514 . A gear shaft 5141 coaxially connected to the rotating shaft member 5151 is disposed at the upper center of the transmission gear 514 .

The gear shaft 5141 may be inserted into the receiving space of the collector body 511 through a hole formed in the lower cover 517 . The gear shaft 5141 may be configured to be inserted into a hollow formed in the rotating shaft member 5151 . That is, the size of the outer circumferential diameter of the gear shaft 5141 may be smaller than the size of the outer circumferential diameter of the rotating shaft member 5151 .

The gear shaft 5141 and the rotating shaft member 5151 may have mechanical structures that engage each other so as to rotate at the same angular velocity. For example, the mechanical structure may be a protrusion and groove structure.

The drive gear 3621 may include a gear body 3621a, a shaft connecting portion 3621b, and gear teeth 3621c.

The gear body (3621a) forms the exterior of the drive gear (3621). Gear teeth 5142 of the transmission gear 514 and gear teeth 3621c engaged with the upper portion of the gear body 3621a are formed and disposed. A pattern 3621d in which protrusions and grooves alternately and continuously may be formed on the lower circumference of the gear body 3621a.

An upper diameter of the gear body 3621a on which the gear teeth 3621c are disposed and a lower diameter of the gear body 3621a on which the pattern 3621d is formed may have different sizes.

A shaft connecting portion 3621b connected to the motor shaft of the compression motor 3622 is formed at the center of the gear body 3621a. The shaft connecting portion 3621b may be formed and disposed in a cylindrical shape inside the gear body 3621a. The shaft connecting portion 3621b may have a hole formed corresponding to the motor shaft into which the motor shaft is inserted.

Thus, when the compression motor 3622 rotates, the drive gear 3621 rotates together.

A plurality of ribs 3621e may be radially disposed on an outer circumferential surface of the shaft connecting portion 3621b to support the shape of the shaft connecting portion 3621b.

The pattern 3621d formed on the drive gear 3621 may be formed such that the widths of protrusions and grooves adjacent to each other are different from each other. The protrusions and grooves formed in the pattern 3621d may be defined as distinct phases according to the size of the formed width.

At this time, the order in which the phases of the pattern 3621d are arranged is in the first direction d1 about the circumference of the gear body 3621a and in the second direction d2 opposite to the first direction d1. It can be formed to be different from each other for .

The pattern 3621d may consist of a set of four phases. Here, the first phase and the third phase may be formed in the form of protrusions, and the second phase and the fourth phase may be formed in the form of grooves. That is, protrusions and grooves may be alternately formed.

Here, the widths of the first to fourth phases may all be formed to be different, and each phase may be distinguished through the size of the width. Taking the embodiment shown in FIG. 28 as an example, protrusions with a width of 1.2 mm are in the first phase, grooves with a width of 0.8 mm are in the second phase, projections with a width of 2.0 mm are in the third phase, and grooves with a width of 1.6 mm are in the second phase. may be defined as the fourth phase.

The arrangement order of each phase may be repeated in the order of 1-2-3-4 when looking at the gear body 3621a of the drive gear 3621 while moving in the first rotation direction rd1. Therefore, when looking at the gear body 3621a of the driving gear 3621 while moving in the second rotation direction rd2 opposite to the first rotation direction rd1, each phase is in the order of 4-3-2-1 will be repeated

In this way, through the arrangement of the directional pattern 3621d formed on the drive gear 3621, the control unit 700, which will be described later, determines whether the drive gear 3621 is currently rotating in the first rotational direction rd1 or in the second rotational direction. (rd2) makes it possible to detect whether it is rotating.

Hereinafter, a detailed structure of the second collecting unit 520 will be described.

32 is a view in which related components of the second collecting unit 520 are separated and developed according to an embodiment of the present invention, and FIG. 33 is a view showing the second collecting unit 520 in an embodiment of the present invention A cross-sectional view from the side.

Referring to FIGS. 32 and 33 , the second collecting unit 520 may include a dust bag 521 , an outer plate 522 and an inner plate 523 .

The dust bag 521 is a component that receives and stores dust sucked from the first cleaner 200 therein.

To this end, the dust bag 521 may be made of a breathable material. More specifically, the dust bag 521 may be made of a material that allows air to pass through but does not transmit foreign substances such as dust. For example, the dust bag 521 may be made of a non-woven fabric material and may have a hexahedral shape based on when the volume is increased.

In the dust bag 521, a dust inlet 5212 is formed. The dust inlet 5212 is formed on the upper side of the dust bag 521 through the dust bag 521, and passes air and dust introduced from the air inlet 3621 of the chamber body 361 into the dust bag 521. It becomes a passage leading to the inside.

The dust bag 521 may include a light transmission hole 5211 . The light transmission hole 5211 may be formed through the dust bag 521 . The light transmission hole 5211 may be formed at a position facing one surface of the transmission panel 524 to be described later. That is, the light transmission hole 5211 may be disposed in front of the dust inlet 5212 . In a state in which the second collecting part 520 is completely inserted into the collecting part accommodating space 360a, the sterilization module 450 may be disposed above the light transmission hole 5211. As a result, sterilization light may be irradiated into the dust bag 521 through the transmission panel 524 .

The outer plate 522 may be coupled to the outside of the top of the dust bag 521 .

The outer plate 522 may include a plate body 5221 in the form of a square flat plate.

Parts of the left and right ends of the plate body 5221 may be inserted into the sliding space of the rail body 3631. From another point of view, left and right ends of the plate body 5221 are fitted to the rail body 3631, and one surface of the plate body 5221 may be supported by an inner lower surface of the rail body 3631. Through this configuration, the plate body 5221 can be inserted into the rail body 3631 in a sliding manner.

A dust inlet 5222 is formed in the plate body 5221 . The dust inlet 5222 serves as a passage for guiding air and dust introduced from the air inlet 3621 of the chamber body 361 into the dust bag 521 .

The outer plate 522 may include a handle 5223.

The handle 5223 may be coupled to the front end of the plate body 5221. The handle 5223 may be integrally formed with the plate body 5221. The handle 5223 may be formed by being vertically connected from the plate body 5221 .

A user may push the outer plate 522 into the rail body 3631 by gripping the handle 5223 . A user can take out the outer plate 522 from the rail body 3631 by gripping the handle 5223 .

The outer plate 522 may include a connecting member 5224 .

The connecting member 5224 may be disposed behind the dust inlet 5222 . The connecting member 5224 may protrude from the lower surface of the outer plate 522 downward by a predetermined length. The connection member 5224 may pass through the dust bag 521 and be coupled to an inner plate 523 to be described later.

The outer plate 522 may include a support member 5225 .

The support member 5225 may be disposed in front of the outer plate 522 . The support member 5225 may protrude from the lower surface of the outer plate 522 downward by a predetermined length.

The support member 5225 is formed in the form of a rib on the left and right sides of the outer plate 522, and the lower end thereof is the lower side of the rail body 3631 based on the state in which the outer plate 522 is inserted into the rail body 3631. You can come into contact with the inside.

The front of the second collecting unit 520 is lifted by the support member 5225 as it is inserted into the collecting unit accommodating space 360a. That is, in a state where the second collecting part 520 is completely inserted into the collecting part accommodating space 360a, the second collecting part 520 is inclined to have a backward-downward slope (see FIG. 35).

Through this configuration, the outer plate 522 may be supported in an elevated state toward the air inlet 3621 of the chamber body 361 .

As described above, in the embodiment of the present invention, the open end face of the air inlet 3621 has a backward-downward slope. At this time, the second collecting part 520 is also inserted into the rail part 363 in an inclined state to have a backward-downward inclination, since the air inlet 3621 and the dust inlet 5222 have an inclination in the same direction. They can be sealed without separation from each other.

The outer plate 522 may include a light transmission hole 5226 .

The light transmission hole 5226 may be formed through the plate body 5221 . The light transmission hole 5226 may be formed at a position opposite to one surface of the transmission panel 524 to be described later. That is, the light transmission hole 5226 may be disposed in front of the dust inlet 5222 .

In a state in which the second collecting unit 520 is completely inserted into the collecting unit accommodating space 360a, the sterilization module 450 may be disposed above the light transmission hole 5226. As a result, sterilization light may be irradiated into the dust bag 521 through the transmission panel 524 .

The inner plate 523 may be coupled to the upper inside of the dust bag 521 .

The inner plate 523 may include a plate body 5231 in the form of a square flat plate.

In the plate body 5231, a dust inlet 5232 is formed. The dust inlet 5232 serves as a passage for guiding air and dust introduced from the air inlet 3621 of the chamber body 361 into the dust bag 521 .

The inner plate 523 may include a sidewall 5233 .

The side wall 5233 is configured to limit and guide the flow direction of the air introduced into the dust bag 521 . Sidewall 5233 may be disposed adjacent to dust inlet 5232 . The sidewall 5233 may protrude downward from an inner surface of the plate body 5231 . That is, the side wall 5233 may extend toward the inner space of the dust bag 521 .

The side walls 5233 may be symmetrically disposed on the left and right sides of the dust inlet 5232. Accordingly, the side wall 5233 may block air introduced into the dust inlet 5232 from flowing left or right.

Meanwhile, in a state in which the inlet cover 525 to be described later is opened, the rear flow of air may also be blocked.

As a result, the air introduced into the dust inlet 5232 flows forward and downward.

Through this configuration, the inflowing dust may be effectively exposed to sterilizing light irradiated in front of the dust inlet 5232 .

The inner plate 523 may include a connecting member insertion groove 5234 .

The connection member insertion groove 5234 may be disposed behind the dust inlet 5232 . The connection member insertion groove 5234 may be formed in a shape through which the plate body 5231 passes. The connecting member 5224 of the outer plate 522 may be inserted into the connecting member insertion groove 5234 .

The inner plate 523 may include an inlet tube 5235.

The inlet pipe 5235 may be coupled to the lower surface of the plate body 5231. The inlet pipe 5235 may be disposed in a form surrounding the dust inlet 5232 . The inlet pipe 5235 may be integrally formed with the plate body 5231. The open cross section of inlet tube 5235 may have a backward-downward slope.

A lower end of the inlet pipe 5235 may be closed by an inlet cover 525 to be described later. With this, the dust inlet 5232 can also be closed.

The inner plate 523 may include an inlet cover fixing member 5236 .

The inlet cover fixing member 5236 may be disposed behind the dust inlet 5232 . The inlet cover fixing member 5236 may be coupled to the lower surface of the plate body 5231 in a form surrounding the connection member insertion groove 5234 . The inlet cover fixing member 5236 may be integrally formed with the plate body 5231.

An inlet cover insertion groove 5236a may be formed in the inlet cover fixing member 5236 . At least a portion of the inlet cover 525 may be inserted into and fixed to the inlet cover insertion groove 5236a. The inlet cover insertion groove 5236a has a backward downward inclined surface and may extend left and right. Thus, the inlet cover 525 can be inserted from the front top to the rear downward.

A transparent panel 524 may be coupled to the inner plate 523 .

When the second collecting unit 520 is inserted into the chamber body 361, the transmission panel 524 is disposed at a position corresponding to the position at which the sterilization module 450 is disposed. That is, when the second collecting unit 520 is inserted into the chamber body 361, the sterilization module 450 and the transmission panel 524 are disposed to face each other.

The transmission panel 524 is made of a material through which sterilization light emitted from the sterilization module 450 can be transmitted toward the inside of the collector body 511 . For example, the transmission panel 524 may be made of a poly methyl methacrylate (PMMA) material.

An inlet cover 525 opening and closing the dust inlet 5232 may be coupled to the inner side of the inner plate 523 . An inlet cover 525 may be disposed at an end of the inlet tube 5235.

The inlet cover 525 may be made of a material having elasticity. For example, the inlet cover 525 may be made of a rubber material.

The inlet cover 525 may open one side of the inlet pipe 5235 by the suction force of the dust collecting motor 391 . That is, the inlet cover 525 may be opened toward the inner space of the dust bag 521 .

One side of the inlet cover 525 may be inserted into and coupled to the inlet cover insertion groove 5236a.

The inlet cover insertion groove 5236a has a large backward-downward slope, whereas the open end surface of the inlet pipe 5235 has a smaller backward-downward slope, so the inlet cover 525 has an inlet cover insertion groove ( 5236a), the shape is deformed into a bent shape at one point.

At this time, restoring force is applied to the inflow cover 525 toward the direction to be unfolded again based on the bent point.

Through this configuration, the inlet cover 525 may be in close contact with the inlet pipe 5235 in a state where the inlet cover 525 is inserted into the inlet cover insertion groove 5236a. That is, the inflow cover 525 is not deflected due to its own weight in a state in which the dust collection motor 391 is not driven.

The inlet cover 525 may keep the dust inlet 5232 closed when the dust collecting motor 391 is not driven, and open the dust inlet 5232 when the dust collecting motor 391 starts to operate.

When the dust collecting motor 391 is operated, the inlet cover 525 is deformed toward the inner space of the dust bag 521 to open the inlet pipe 5235, and when the dust collecting motor 391 is stopped, the inlet cover 525 is restored by elasticity and the inlet pipe 525 is stopped. Close (5235).

Accordingly, when the second collecting unit 520 is separated from the cleaner station, it is possible to prevent dust from scattering to the outside, flying insects from escaping, or odor from spreading.

In addition, even when the second collecting unit 520 is coupled to the cleaner station, when the dust collecting motor 391 is not driven, the inlet pipe 5235 is closed, so that dust or odor does not flow backward through the first flow path 381. It has a preventive effect.

34 is a perspective view showing a state in which the second collecting unit 520 is inserted into the chamber body 361 according to an embodiment of the present invention, and FIG. 35 is a perspective view showing a second collecting unit 520 according to an embodiment of the present invention. Reference numeral 520 is a view showing a flow path of air related to dust collection in a state where the chamber body 361 is inserted.

When an airflow is formed by the suction force of the dust collection motor 391, the air containing foreign substances flowing from the inside of the dust bin 220 of the first cleaner 200 passes through the first flow path 381 to the dust bag 521. and exits the dust bag 521 leaving only foreign substances in the dust bag 521.

At this time, the flow of dust introduced through the first passage 381 in the left and right directions is blocked by the side walls 5233 and the flow in the rear direction is blocked by the inflow cover 525, as shown in the direction of the arrow shown in FIG. , It flows forward and downward toward the sterilization light irradiated by the sterilization module 450.

In addition, the air exiting the dust bag 521 passes through the pre-filter module 470 and flows to the dust collecting motor 391.

On the other hand, when the dust collection motor 391 is driven to form an air flow in the second collecting unit 520, the gear passage hole 3623a is exposed as it is without clogging, so that the suction force is applied to the gear passage hole 3623a (See the direction of the dotted line arrow in FIG. 33)

As such, when a suction force is directly applied to the compression motor 3622 through the gear passage hole 3623a, a failure of the compression motor 3622 may be caused.

36 is an enlarged cross-sectional view of the sealing member 3623 sealing the gear passage hole 3623a in the embodiment of the present invention.

In an embodiment according to the present invention, the compression driving unit 362 may further include a sealing member 3623 disposed between the driving gear 3621 and the chamber body 361 .

The sealing member 3623 may be disposed along the entire outer circumference of the gear body 3621a of the drive gear 3621 . The sealing member 3623 may be disposed between the outer surface of the gear body 3621a of the driving gear 3621 and the lower outer surface of the chamber body 361 .

As such, the sealing member 3623 may seal between the gear passage hole 3623a and the compression motor 3622 to block air flow between the compression motor 3622 and the collecting unit accommodating space 360a.

The sealing member 3623 may include a first sealing part contacting the chamber body 361 and a second sealing part contacting the gear body 3621a. The first sealing part and the second sealing part may be configured to be connected to each other at one end and spaced apart from the other end.

Through this configuration, as suction force is applied by the dust collecting motor 391, the sealing portion is compressed in a direction in which the other side of the first sealing portion and the other side of the second sealing portion become closer to each other. Accordingly, the sealing force is further strengthened by driving the dust collecting motor 391, and direct application of suction force to the compression motor 3622 is prevented.

Meanwhile, the cleaner station may further include a controller 700.

The controller 700 is a component that controls the operation of each component of the cleaner station. The controller 700 may be mounted on a printed circuit board.

The controller 700 may include all types of devices capable of processing data, such as a processor. Here, a 'processor' may refer to a data processing device embedded in hardware having a physically structured circuit to perform functions expressed by codes or instructions included in a program, for example. As an example of such a data processing device built into hardware, a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated (ASIC) circuit), field programmable gate array (FPGA), etc., but the scope of the present invention is not limited thereto.

In an embodiment of the present invention, the control unit 700 may detect a rotation direction change of the compression motor 3622.

As described above, when the compression motor 3622 rotates in one direction and the force applied to the compression motor 3622 exceeds a set value, the rotation of the compression motor 3622 is converted to the other direction. At this time, the force applied to the compression motor 3622 is a resistance force (torque) generated as the rotary plate 5153 presses the dust, and when the resistance force reaches a set value, the rotation of the compression motor 3622 is directed in the direction configured to be converted.

That is, the compression motor 3622 is connected to the rotary plate 5153, and the rotation direction is changed only when the rotary plate 5153 presses dust.

The controller 700 may control driving of the compression motor 3622 at any stage of the dust emptying process.

In a possible embodiment, driving of the compression motor 3622 may be performed at the same time as the first cleaner 200 is coupled to the coupler 320 . Information related to the coupling of the first cleaner 200 may be detected by a coupling sensor 325 disposed on one side of the coupling unit 320 and transmitted to the controller 700 .

In another possible embodiment, the driving of the compression motor 3622 may be performed after the driving of the dust collecting motor 391 is finished.

In another possible embodiment, the driving of the compression motor 3622 may be performed before and after driving the dust collection motor 391, respectively.

The control unit 700 may detect whether the rotation direction of the compression motor 3622 is changed within a predetermined time from when the compression motor 3622 starts driving. The time period should be set sufficiently longer than the expected time for the rotation plate 5153 to come into contact with one surface of the fixed plate 5152 when the rotation plate 5153 starts to rotate from the initial position.

The rotation direction change detection may be performed by detecting the arrangement order of the pattern 3621d formed on the driving gear 3621 . To this end, the compression driving unit 362 may further include a photo interrupter (not shown) disposed adjacent to the driving gear 3621 .

If the phase of the pattern 3621d detected by the photointerrupter has an arrangement order of 1-2-3-4, the compression motor 3622 is rotating in the first direction. If the phase of the pattern 3621d detected by the photointerrupter has an arrangement order of 4-3-2-1, the compression motor 3622 is rotating in the second direction (see FIG. 28).

The controller 700 may drive the compression motor 3622 regardless of the type of the collecting unit 500 currently coupled to the cleaner station.

If the first collecting part 510 is inserted into the chamber body 361, the rotation direction of the compression motor 3622 is necessarily changed within a predetermined time.

If the second collecting unit 520 is inserted into the chamber body 361, no load is applied to the compression motor 3622 even after a predetermined time elapses, so the compression motor 3622 only rotates in the same direction, A change of direction of rotation is not made.

That is, the control unit 700 rotationally drives the compression motor 3622 to determine whether or not the rotation direction of the compression motor 3622 is changed within a predetermined period of time, so that the collection unit 500 currently coupled to the cleaner station 300 is controlled. type can be determined.

Although the present invention has been described in detail through specific examples, this is for explaining the present invention in detail, the present invention is not limited thereto, and the present invention is within the technical spirit of the present invention. It is clear that modification or improvement is possible by the person.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be clarified by the appended claims.
