[0001] This utility model relates to the field of kitchen equipment technology, specifically to a pulsator cleaning machine and an integrated sink. Background Technology

[0002] The sink-type washer inside the integrated sink is used to wash dishes, fruits and vegetables, etc.

[0003] To improve cleaning results, people have applied the rotating impeller cleaning solution to sink-type dishwashers. For example, the Chinese patent application number CN201820891413.7, "A Sink Dishwasher", places the impeller assembly at the bottom of the dish rack to rotate and repeatedly rise and fall, enhancing the turbulence of the water and making the cleaning more efficient and faster.

[0004] Currently, the water tank filtration solutions on the market use metal filter screens, which tend to float up and leave the drain outlet under the rotational force of the water when applied to a pulsator washer. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a pulsator cleaning machine that can ensure the stable position of the filter screen, in light of the current state of the technology.

[0006] The second technical problem to be solved by this utility model is to provide an integrated water tank that uses the above-mentioned impeller cleaning machine.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a pulsator cleaning machine, including an outer tub, an inner basket disposed inside the outer tub, and a driving component for driving the inner basket to rotate. The bottom of the outer tub has a drain outlet, and the drain outlet is covered with a filter screen with mesh. The feature is that a magnet is provided on the filter screen, and a metal part that can be attracted by the magnet is provided on the outer tub at an external position corresponding to the magnet.

[0008] To prevent the filter from shifting during operation and affecting the filtration effect, the bottom wall inside the outer barrel is partially recessed to form a recessed part. The drain outlet is provided on the bottom wall of the recessed part, and the filter is housed in the recessed part.

[0009] To buffer the drainage, the bottom of the filter screen has an annular protrusion, which surrounds the bottom wall of the recess and the bottom wall of the filter screen to form a buffer cavity. The mesh and the drain outlet are connected to the buffer cavity.

[0010] To facilitate the processing of the annular boss, the edge of the filter screen is bent downwards to form the annular boss.

[0011] To facilitate the installation of magnets on the filter screen, the annular boss is provided with at least two spaced mounting seats, and the number of magnets is at least two, corresponding to the mounting seats, with each magnet embedded in the corresponding mounting seat.

[0012] To achieve uniform adsorption, the metal part is in the form of a sheet and is installed on the bottom wall outside the recess.

[0013] To facilitate the insertion of the filter into the recess, the filter has a folded edge that gradually extends outward from bottom to top, and the side wall inside the recess has a mating surface that matches the folded edge.

[0014] To facilitate the placement and removal of the filter, the filter surface has a grip portion in the middle for the user to hold.

[0015] To facilitate user gripping, the grip is sheet-shaped, and both sides of the top of the grip are provided with protruding lugs.

[0016] To conveniently remind users whether the filter is in place, a Hall sensor is installed on the outer tub. When the filter covers the drain outlet, the magnet is within the sensing range of the Hall sensor.

[0017] To facilitate drainage control, a drain pipe is connected to the drain outlet, and a drain valve is installed on the drain pipe.

[0018] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: an integrated water tank, including a water tank, characterized in that: it also includes the above-mentioned impeller cleaning machine, which is disposed on the water tank.

[0019] To simplify the structure, the water tank includes interconnected tank bodies and a fixed cylinder, with the outer tank and the fixed cylinder being an integral piece.

[0020] Compared with the prior art, the advantages of this utility model are: by providing a magnet on the filter screen and setting a metal part that can be attracted by the magnet at the corresponding external position on the outer barrel, the filter screen can be kept in the position covering the drain outlet, preventing it from floating up under the action of water rotation force and thus removing the cover from the drain outlet, thereby achieving stable positioning of the filter screen.

[0027] like Figures 1 to 4 The image shows a preferred embodiment of the integrated sink of this utility model. The integrated sink includes a sink 1 and a pulsator washing machine disposed on the sink 1. The pulsator washing machine includes an outer tub 2, an inner basket 3, a drive unit 4, a filter screen 5, a magnet 6, and a Hall sensor 7.

[0028] The water tank 1 includes a tank body 11 and a fixed cylinder 12 that are connected to each other.

[0029] The outer tub 2 is located inside the fixed tube 12. In this embodiment, the outer tub 2 and the fixed tube 12 are an integral piece. Specifically, the outer tub 2 has a water inlet 21 on its side wall; a recessed portion 22 is formed at the eccentric position of the bottom wall inside the outer tub 2, and a drain outlet 221 is provided on the bottom wall of the recessed portion 22. A drain pipe 2211 is connected to the drain outlet 221, and a drain valve 2212 is installed on the drain pipe 2211; a sheet-shaped metal part 23 that can be attracted by a magnet 6 is installed on the bottom wall outside the recessed portion 22.

[0030] The inner basket 3 is rotatably mounted inside the outer bucket 2.

[0031] The driving component 4 is a motor, which is installed at the bottom of the outer tub 2. The power output shaft of the motor passes through the bottom wall of the outer tub 2 and is connected to the inner basket 3 to drive the inner basket 3 to rotate.

[0032] The filter screen 5 is housed in the recess 22 and is used to cover the drain outlet 221. Specifically, the surface of the filter screen 5 has a plurality of spaced mesh holes 50; the edge of the filter screen 5 is bent downward to form an annular protrusion 51, which surrounds the bottom wall of the recess 22 and the bottom wall of the filter screen 5 to form a buffer cavity 510. The mesh holes 50 and the drain outlet 221 are connected to the buffer cavity 510. In addition, two spaced mounting seats 511 are provided in the annular protrusion 51; the edge of the filter screen 5 has a folded edge 52 that gradually extends outward from bottom to top. Correspondingly, the side wall inside the recess 22 has a mating surface 222 that matches the folded edge 52, so as to facilitate the filter screen 5 being placed into the recess 22; the middle part of the surface of the filter screen 5 has a gripping part 53 for the user to hold, so as to facilitate the removal and placement of the filter screen 5. In this embodiment, the gripping part 53 is sheet-shaped, and the top two sides of the gripping part 53 are provided with lugs 531.

[0033] There are two magnets 6, which correspond to the mounting base 511. Each magnet 6 is embedded in the corresponding mounting base 511. Since there is a metal part 23 on the outer barrel 2 corresponding to the magnet 6, the filter screen 5 can be kept in the recess 22, preventing it from floating up under the action of water rotation force and removing the cover of the drain outlet 221, thus achieving stable positioning of the filter screen 5.

[0034] The Hall sensor 7 is installed on the side wall outside the recess 22. When the filter screen 5 covers the drain outlet 221, the magnet 6 is within the sensing range of the Hall sensor 7. Thus, when the filter screen 5 is not in place, the Hall sensor 7 can send a signal to remind the user.

[0035] The working principle of this embodiment is as follows:

[0036] (1) During operation, since the filter screen 5 is provided with a magnet 6 and the outer barrel 2 is provided with a metal part 23 corresponding to the magnet 6, the filter screen 5 can be kept in the recess 22, preventing it from floating up under the action of the rotation force of the water and removing the cover of the drain outlet 221, thus achieving the stable position of the filter screen 5.

[0037] (2) When the filter needs to be cleaned, the user only needs to pinch the grip 53 to take out the filter 5 for cleaning. After cleaning, the filter 5 can be put into the recess 22 along the mating surface 222.

[0038] The advantages of this utility model are:

[0039] First, by using the metal part 23 in conjunction with the magnet 6, the filter screen 5 is kept in the recess 22, preventing it from floating up under the rotational force of the water and thus removing the cover of the drain outlet 221, thereby achieving stable positioning of the filter screen 5.

[0040] Second, by setting the gripping part 53 on the filter screen 5 and the cooperation between the folded edge 52 on the filter screen 5 and the inner mating surface 222 of the recessed part 22, and with the help of the magnet 6, the problems of difficult picking up and installing the filter screen 5 at a certain depth space position are solved.

[0041] Third, by using Hall sensor 7 in conjunction with magnet 6, Hall sensor 7 sends a signal to remind the user when filter screen 5 is not in place, preventing the user from forgetting to put in the manually cleaned filter screen 5, and preventing large particles of dirty water from entering the drain and causing blockage. This achieves a high user experience and long lifespan for the machine.
