The pump shell 10 is provided with a pump cavity 11 and a first outlet channel 12, the first outlet channel 12 is positioned at the bottom side 7 of the pump shell (the bottom side is the bottom of the heating pump after being installed), the pump cavity 11 is communicated with the first outlet channel 12, and the first outlet channel 12 is communicated with the drainage pipeline 5; the heat pump 1 comprises a sealing plug 13 and a first sealing ring 132, wherein the wall corresponding to the first outlet channel 12 is in sealing connection with the sealing plug 13, the sealing plug 13 is provided with a first through hole 131 penetrating through two ends of the body, the wall corresponding to the first through hole 131 is provided with a first groove 134, and the first sealing ring 132 is at least partially positioned in the first groove 134;

the first container 2 comprises a second sealing ring 22, a boss 23 protruding towards the inner cavity is arranged at the bottom wall part of the first container 2, a second through hole 231 penetrating through the body of the boss 23 is arranged on the boss 23, a second groove 232 is arranged on the wall corresponding to the second through hole 231, and the second sealing ring 22 is at least partially positioned in the second groove 232; (wherein the boss 23 contributes to the stability of the second branch 32 described later)

The transmission 3 further comprises a main body portion 30 and a second branch portion 32; the second support part is fixedly connected with or integrally arranged with the main body part, and the first support part is fixedly connected with or integrally arranged with the other end of the main body part; the first branch part and the second branch part are arranged in parallel, and an included angle between the first branch part and the main body part is approximately 90 degrees; the first transmission part 31 is at least partially positioned in the first through hole 131, and the first sealing ring 132 is pressed between the wall corresponding to the first groove 134 and the first transmission part 31; the second branch portion extends into the first container, and the second branch portion 32 is at least partially located in the second through hole 231, and the second sealing ring 22 is pressed between the wall corresponding to the second groove 232 and the second branch portion 32. The purpose of this is to prevent leakage during movement of the transmission element 3.

The first adjusting element 33 is connected with the transmission member 3 or the first adjusting element 33 is integrally arranged with the transmission member 3, in this embodiment the first adjusting element 33 is fixedly connected with the transmission member 3, in particular the first adjusting element 33 is in threaded connection with the first transmission portion 31; the first adjusting element 33 is at least partially located in the first outlet channel 12 or the drain pipe 5, in this embodiment the first adjusting element 33 is at least partially located in the first outlet channel 12, and a gasket 14 is arranged between the first adjusting element 33 and the sealing plug 13, the gasket 14 being in abutment with the end of the sealing plug 13; along the axial direction of the first through hole 131, the projection of the corresponding wall of the first through hole 131 is located at the first adjusting element 33. In this way, the first adjusting element 33 is able to seal the opening of the first through hole 131 at one end of the sealing plug 13, thereby blocking the communication of the first outlet channel 12 with the first through hole 131.

The sealing plug 13 has at least one communication hole 133, and the communication hole 133 is arranged on the side wall of the sealing plug 13 body, is communicated with the first through hole 131, and is also communicated with the drainage pipeline 5; the first transmission portion 31 includes a first diameter portion 311 and a second diameter portion 312, the diameter of the first diameter portion 311 is smaller than the diameter of the second diameter portion 312, the first adjustment element 33 is fixedly connected with the first diameter portion 311 (specifically, an external thread is provided at an end portion of the first diameter portion 311, a groove is provided in the first adjustment element 33, an internal thread is provided in a wall corresponding to the groove, and the first adjustment element 33 is in threaded connection with the first diameter portion 311, thereby facilitating assembly), when the first adjustment element is located at the third position, along a center line direction of the communication hole, and a projection of the wall corresponding to the communication hole is located at least partially at the first diameter portion. In this way, the first outlet channel 12 can communicate with the communication hole 133 when the transmission member 3 is in the first position (i.e. when the first adjusting element 33 is remote from the sealing plug 13).

Thus, when the transmission member 3 is in the first position (i.e., when the first adjusting member 33 is away from the sealing plug 13), the accumulated water in the heating pump 1 flows into the first outlet passage 12, then passes through the first through hole 131 and the communication hole 133, and flows into the drain pipe 5 (the drain pipe 5 directly or indirectly communicates with a pipe outside the dishwasher, such as a sewer pipe), thereby being discharged.

When the transmission member 3 is in the second position (i.e. when the first adjusting element 33 abuts against the gasket 14), the first adjusting element 33 seals the opening of the first through hole 131 at one end of the sealing plug 13, thereby blocking the communication between the first outlet channel 12 and the first through hole 131.

The transmission member 3 further includes a limiting member 34, where the limiting member 34 is fixedly connected with the second support portion 32 or the limiting member 34 is integrally disposed with the second support portion 32, and in this embodiment, the limiting member 34 is in threaded connection with the second support portion 32 (specifically, an external thread is disposed at an end portion of the second transmission member 3, a groove is disposed in the limiting member 34, and an internal thread is disposed on a wall corresponding to the groove). The limiting member 34 is at least partially located in the inner cavity 21, and along the axial direction of the second through hole 231, the projection of the wall corresponding to the second through hole 231 is located in the limiting member 34. This is to ensure that the stopper 34 is larger than the aperture of the second through hole 231, thereby playing a role of stopper. An elastic member 35 is disposed between the boss 23 and the limiting member 34, in this embodiment, the elastic member 35 is a spring, and the outer diameter of at least a portion of the spring is gradually reduced along the direction of the boss 23 toward the limiting member 34. The spring here is responsible for providing the power required to return the transmission member 3 from the second position to the first position.

The first container 2 is provided with a limiting step, when the transmission member 3 is located at the second position, the filtering member 4 is at least partially abutted with the limiting step, and the spring is in a compressed state. This is to press the stopper 34 for the filter element 4 to be damaged.

The working process comprises the following steps:

each time the dishwasher is operated, the filter element 4 contains debris (e.g. food residues etc.), which needs to be manually removed and cleaned.

When the dishwasher is in a normal working state, the filter element 4 is abutted with the limiting element 34 of the transmission element 3, the spring is in a compressed state, the transmission element 3 is in a second position, and the first adjusting element 33 blocks the communication between the first outlet and the first through hole 131; the heat pump 1 normally supplies water to the system.

After the dishwasher is operated, the filter element 4 is removed, the transmission element 3 is brought to the first position under the action of the spring, the first adjusting element 33 is remote from the sealing plug 13, the first outlet channel 12 communicates with the drain line 5, and the accumulated water in the pump chamber 11 is drained from the drain line 5 via the first outlet channel 12.

It should be noted that: although the present application has been described in detail with reference to the above embodiments, it will be understood by those skilled in the art that the present application may be modified, combined or equivalent thereto, and all modifications and improvements thereto without departing from the spirit and scope of the present application are intended to be included in the scope of the claims of the present application.
