BACKGROUND A vacuum cleaner is a device that uses a member such as a pipe to suck out dust existing on the floor or in a place that is difficult to reach. The vacuum cleaner includes a motor and a dust bin. The rotating motor forms a vacuum inside the dust bin, and the pressure inside the dust bin is lower than the external pressure, so that foreign substances such as dust can be sucked in by the pressure difference.

The type of vacuum cleaner can be divided into a hand cleaner 500 that cleans the floor, etc. while holding and moving by a user, and a robot cleaner 600 that automatically sets a path and performs cleaning. Both types of vacuum cleaners have a dust bin and a battery inside, and the user must remove the dust inside each vacuum cleaner by removing the dust bin from each vacuum cleaner.

The hand cleaner 500 and the robot cleaner 600 may be charged using a cradle connected to a power source. It is common for each device to use a different charging cradle. The charging cradle has to be connected to a power source and takes up space. Therefore, providing one or more cradles in the house lowers the efficiency of space use, and there is a problem that requires several power sources.

The cleaner station 1 according to the embodiments has a function of simultaneously combining two types of vacuum cleaners. Using this, it is possible to simultaneously charge different types of vacuum cleaners with only one power source. Also, it is possible to increase the efficiency of space use.

The vacuum cleaner station 1 has a flow path structure and a dust storage box 300 therein, so that the material inside the dust bin provided in each vacuum cleaner can be sucked. At least one dustbin including different types of cleaners may be managed by using one dustbin 300 .

The second station 200 may include a second suction unit 210 that sucks dust from the dust container of the robot cleaner 600 . The dust bin included in the robot cleaner 600 may be connected to the second suction unit 210 , and dust and foreign substances inside the dust bin may be discharged out of the dust bin by the suction force applied by the second suction unit 210 .

Specifically, when the hand cleaner 500 is coupled, a portion where the dust container of the hand cleaner 500 is located may be seated in the first station 100 . In this case, the suction pipe 520 may be disposed in the longitudinal direction of the cleaner station 1 . The second station 200 includes a flat structure protruding forward from the lower portion of the cleaner station 1 , and the robot cleaner 600 may be seated thereon.

Hereinafter, with reference to FIG. 2 , an internal structure of the cleaner station 1 for sucking dust will be described.

FIG. 2A is a cross-sectional view of a flow path structure and an exhaust path P of a cleaner station 1 according to embodiments, as viewed from the side, and FIG. 2B is a flow path of the cleaner station 1 according to embodiments. It is a cross-sectional view of the structure and the exhaust path (P) viewed from the rear.

In the cleaner station 1 according to the embodiments, the dust storage box 300 for storing the suctioned dust and the dust suctioned from the first suction unit 110 and/or the second suction unit 210 are discharged. A unit 310 may be provided. The dust box 300 communicates with the dust inlet 310 , and dust sucked from the first suction unit 110 and the second suction unit 210 is accommodated in the dust box 300 .

The cleaner station 1 according to the embodiments may include a suction motor 800 that provides power for sucking dust.

Specifically, the suction motor 800 may be a fan motor. The suction motor 800 receives power to rotate the fan, and the flow of air generated by the rotation of the fan may function to lower the pressure inside the dust storage box 300 .

The cleaner station 1 according to the embodiments may include a first flow path 111 communicating with the first suction unit 110 and a second flow path 211 communicating with the second suction unit 210 . . In addition, the cleaner station 1 may further include a third flow path 311 through which the first flow path 111 and the second flow path 211 merge to communicate with the dust inlet 310 .

Specifically, one end of the first flow path 111 communicates with the first suction unit 110 , and dust of the hand cleaner 500 may be sucked. The other end of the first flow path 111 may be connected to one end of the third flow path 311 . In addition, one end of the second flow path 211 communicates with the second suction unit 210 , and dust of the robot cleaner 600 may be sucked. The other end of the second flow path 211 may be connected to one end of the third flow path 311 . The dust sucked along the first flow path 111 and the second flow path 211 joins at one end of the third flow path 311 . The other end of the third flow path 311 communicates with the dust inlet 310 , and the suctioned dust passes through the dust inlet 310 and is received into the dust storage box 300 .

The air P, which is also sucked in to suck the dust, may be exhausted through one surface of the cleaner station 1 after filtering the included dust.

The first flow path 111 and the second flow path 211 according to the embodiments may be selectively opened and closed in response to the coupling state of the hand cleaner 500 and the robot cleaner 600 .

Specifically, when the cleaner station 1 simultaneously sucks dust from the hand cleaner 500 and the robot cleaner 600 , there is a possibility that the suction power may be reduced. If sufficient suction power is not provided to the dust bin of the vacuum cleaner, dust and foreign substances may remain inside the dust bin even after the suction process is completed.

The first flow path 111 and the second flow path 211, or, in other words, as the first suction unit 110 and the second suction unit 210 are selectively opened and closed, the suction power provided by the suction motor 800 It is possible to focus on one side. Hereinafter, the description of opening and closing the first flow path 111 has the same meaning as the description of opening and closing the first suction unit 110 , and may be used interchangeably. Similarly, the description of opening and closing the second flow path 211 has the same meaning as the description of opening and closing the second suction unit 210 , and may be used interchangeably.

Specifically, when the cleaner station 1 closes the second suction unit 210 and sucks the dust of the hand cleaner 500 , air may be introduced more rapidly from the first suction unit 110 . Conversely, when the first suction unit 110 is closed and dust of the robot cleaner 600 is sucked, air may be introduced more rapidly from the second suction unit 210 .

Therefore, when only the hand cleaner 500 is coupled, the cleaner station 1 can suck the dust of the hand cleaner 500 with the first suction unit 110 open and the second suction unit 210 closed. have. In addition, when only the robot cleaner 600 is coupled, dust of the robot cleaner 600 may be sucked while the second suction unit 210 is opened and the first suction unit 110 is closed.

In addition, when both the hand cleaner 500 and the robot cleaner 600 are coupled to the cleaner station 1 , the first suction unit 110 is opened and the second suction unit 210 is closed according to the user's selection. The dust of the hand cleaner 500 may be sucked while the hand cleaner 500 is left alone, or the dust of the robot cleaner 600 may be sucked while the second suction unit 210 is opened and the first suction unit 110 is closed.

A backflow phenomenon may occur while the vacuum cleaner station 1 sucks dust. In this case, a part of the dust moving along the flow path may be discharged to the external space. In addition, there is a possibility that the dust remaining inside the flow path may be blown into the external space by convection. In order to prevent dust from scattering in the indoor space, the cleaner station 1 may include a sealing member 350 for closing the flow path.

Specifically, at least one of the dust inlet 310 , the first suction unit 110 , and the second suction unit 210 may include a sealing member 350 that prevents dust from passing therethrough. The sealing member 350 may be made of a rubber material. In a state in which the hand cleaner 500 is coupled, the sealing member 350 of the first suction unit 110 may be opened, and in the state in which the robot cleaner 600 is coupled, the sealing member 350 of the second suction unit 210 is coupled. ) can be opened.

For example, referring to FIG. 3 , the communication hole 421 may be formed in a substantially circular shape to correspond to the shape of the end of the first flow path 111 . Also, if the shape of the first flow path 111 is changed, it may be changed correspondingly. Accordingly, it is possible to prevent the outflow of the gas guided from the first flow path 111 to the third flow path 311 .

At one side of the opening/closing part 420 , a locking groove 422 in which an opened state extends to a predetermined width may be formed. The locking groove 422 is a space into which the locking protrusion 432 of the rotating disk 430 to be described later is fitted and coupled, and details will be described later.

Conversely, when the second flow path 211 is switched from the open state to the first flow path 111 open state, the opening/closing unit 420 may slide backward. Accordingly, the opening/closing unit 420 may selectively open and close the first flow path 111 or the second flow path 211 .

In another embodiment, the communication hole 421 may be formed to open the second flow path 211 . In this case, the second flow path 211 and the communication hole 421 may meet in a state in which the opening/closing part 420 is moved to the rear. Accordingly, the gas sucked through the second flow path 211 may be guided to the third flow path 311 . In this case, the opening and closing parts excluding the communication hole 421 may seal the first flow path 111 and the third flow path 311 .

Therefore, the locking projection 432 can be moved by pulling the opening and closing portion 420 when the rotating disk 430 rotates. That is, a function of converting the rotational motion of the rotating disk 430 into a linear motion of the opening/closing unit 420 may be performed.

Specifically, when the disk body 431 rotates, the locking protrusion 432 rotates together along the rotation direction of the disk body 431 . At this time, the locking protrusion 432 is coupled to the locking groove 422 , it rotates in the circumferential direction of the disk body 431 and can be moved by pulling the opening/closing part 420 . Through this, the opening/closing part 420 can move linearly, and further, the first flow path 111 and the second flow path 211 can be selectively opened and closed.

The micro switch 480 may be disposed to determine the rotation and position state of the opening/closing unit 420 and the rotating disk 430 .
