In a washing machine in which the contribution of the bottom wash assembly 21 to the cleaning function of the washing machine is greatest, an optimum design is to connect the bottom wash assembly 21 with the wash pump 4 which is capable of providing the greatest power. In this embodiment, the water flow rate of the first water outlet portion 410 is greater than the water flow rate of the second water outlet portion 420, and the diameter of the first water outlet portion 410 is greater than the diameter of the second water outlet portion 420. The bottom of the washer is also provided with a cup 3 for supplying washing water to the washer pump, in this embodiment a first cup 31 communicating with a first pump housing 41 and a second cup 32 communicating with a second pump housing 42. In some embodiments, the first cup 31 and the first pump housing 41, and the second cup 32 and the second pump housing 42, respectively, may be in communication via a pipe. In this embodiment, the first cup 31 and the first pump case 41 are integrally formed, and the first cup 31 and the first pump case 41 are communicated through a water inlet (not shown); the second water cup 32 and the second pump shell 42 are integrally formed, and the second water cup 32 and the second pump shell 4 are communicated through a water inlet (not shown), so that the butt joint pipeline between the water cup and the pump shell can be reduced, the dirt residue of a washing system is effectively reduced, and the peculiar smell is reduced. The first water cup 31 is provided with a water inlet 312 for connecting a water tap outside the cleaning machine and introducing cleaning water into the cleaning machine; the second cup 32 is provided with a drain port (not shown) for discharging the washing water after the washing by the washing machine.

The first cup 31 and the second cup 32 are provided with openings at one side of the bottom wall of the cleaning cavity 1, and the first cup 31 and the second cup 32 are communicated with the water outlet area 11 through the openings. Since the flow rate of the first water outlet portion 410 is greater than the flow rate of the second water outlet portion 420, the first water cup 31 should receive a larger volume of cleaning water in the same time period, therefore, the area of the first water outlet area 111 is greater than that of the second water outlet area 112, the volume of the first water cup 31 is greater than that of the second water cup 32, and the horizontal cross-sectional area of the first water cup 41 is greater than that of the second water cup 42. The first water outlet zone 111 is further provided with a screen 113 for filtering solid waste in the cleaning water. In this embodiment, the first cup 31 and the second cup 32 are two cups 3 independently disposed, but in other embodiments, the first cup 31 and the second cup 32 may also be integrally disposed in a communicating manner, and may be specifically selected according to the internal structure and space of the cleaning chamber 1. The first water cup 31 is provided with a heating component 311 for heating the cleaning water, so that the dish washing efficiency is higher. In one embodiment, the heating element 311 is a heating plate disposed on a sidewall of the first cup 31. Of course, the heating plate can also be arranged on the second water cup 32, or on both the first water cup 31 and the second water cup 32.

When the washing machine is operated, clean washing water is introduced into the first cup 31 from the water inlet 312 and heated by the heating member 311 installed at the sidewall of the first cup 31. After the washing water with a certain temperature is introduced into the bottom washing assembly 21 by the first pump housing 41, the washing water falls on the mounting plate 12 under the action of gravity after a washing operation, and enters the first water cup 31 and the second water cup 32 through the first water outlet area 111 and the second water outlet area 112, the washing water is continuously heated by the heating assembly 311, and is introduced into the bottom washing assembly 21, the middle washing assembly 22 and the top washing assembly 23 through the first water outlet portion 410, the second water outlet portion 420 and the third water outlet portion 421 by the washing pump. After the second cleaning, the cleaning water falls back into the first cup 31 and the second cup 32 again, and the cleaning operation is completed by the circulation. After the cleaning operation is completed, the cleaning water is discharged from the cleaning machine through the water discharge port.

To sum up, this application uses two impellers of a motor drive, can improve the water pressure of water portion department under the prerequisite of practicing thrift cost and weight reduction to improve the spray intensity of washing subassembly 2 and can improve injection stability.
