[0044] In the embodiment of the present invention, in order to stabilize the pressure of the water flowing out of the water inlet chamber 1 and avoid the change of the water shape of the washing machine when the water pressure is too high or too low, the following settings are made:

[0045] like Figures 1 to 8 As shown, a plurality of columnar pressure-stabilizing ribs 2 are arranged in the water inlet cover 100, and the columnar pressure-stabilizing ribs 2 are arranged at intervals in a ring centered on the inlet of the water inlet chamber 1, so that the water flow flowing into the water inlet chamber 1 from the inlet 5 can be buffered and diverted by the columnar pressure-stabilizing ribs 2 arranged in various radial directions. The columnar pressure-stabilizing ribs 2 can be used to disperse the water flow in the water inlet chamber 1 when the inlet water pressure is low, regulate the inlet water flow when the inlet water pressure is too high, and avoid overflow from the side walls or top walls of the water inlet chamber 1.

[0046] The water inlet cover 100 is vertically installed in the washing machine disc base 400. The water inlet cover 100 is in the shape of a rectangular parallelepiped. The front opening of the water inlet cover 100 is correspondingly snapped onto the inner peripheral side wall 401 of the washing machine disc base 400. The water inlet flow in the water inlet cavity 1 is injected into the washing machine barrel by utilizing the structure arranged on the disc base 400. An inlet 5 is arranged in the middle of the rear side wall 9 of the water inlet cover 100, and the inlet 5 is connected to the water inlet valve 200 via a connecting pipe 300.

[0047] The rear side of the square water inlet cover 100 is provided with a plurality of columnar pressure-stabilizing ribs 2 arranged at intervals and extending horizontally forward, and a gap is provided between the extended end of the columnar pressure-stabilizing rib 2 and the inner peripheral side wall 401 of the washing machine disc seat 400, so as to ensure that the pressure-stabilizing rib 2 can fully divide the pressure of the water flow in the water inlet chamber 1 and can also effectively support the water inlet cover 100 after assembly to avoid interference when the water flowing through the water inlet chamber 1 flows out from the outlet 4 provided on the inner peripheral side wall 401 of the disc seat 400; an inlet 5 extending forward and backward along the axis is provided in the middle of the rear side wall of the water inlet cover 100, and the rear side wall of the water inlet cover 100 has a plurality of concentric rings centered on the inlet 5, and a plurality of columnar pressure-stabilizing ribs 2 are arranged at intervals on each concentric ring, one end of the columnar pressure-stabilizing rib 2 is connected to the rear side wall 9 of the water inlet cover 100, and the other end extends to the open side and is freely arranged. Preferably, the axis of each columnar pressure-stabilizing rib 2 is parallel to the axis of the inlet 5 of the water inlet chamber 1 , so as to ensure that the pressure-stabilizing rib 2 can effectively interfere with and divert the water flow flowing from the inlet 5 into the water inlet chamber 1 .

[0048] The cross section of each columnar stabilizing rib 2 can be any shape such as circular, square, triangular, polygonal, elliptical, etc. Figures 4 to 6 As shown, the cross-section of each columnar pressure-stabilizing rib 2 is set to be a circle with the same radial size, so that when the incoming water flow is diverted and interfered, the arc-shaped outer wall can be used to smoothly guide the water flow and reduce the water pressure change of the incoming water flow of the washing machine.

[0049] In the embodiment of the present invention, due to the limitation of the internal space of the square water inlet hood 100, a circular inlet 5 extending horizontally frontward and rearward is arranged in the middle of the square rear side wall 9 of the water inlet hood 100, and all or part of a plurality of concentric circles with the center of the inlet 5 as the center are arranged on the square rear side wall 9; at the same time, preferably, the radial dimension difference of each concentric circle is enlarged with the radial dimension of the circular inlet 5, that is, the radius difference between adjacent concentric circles is equal to the radius of the circular inlet 5; and the spacing between adjacent columnar pressure-stabilizing ribs 2 arranged at intervals on each concentric circle is set equal.

[0050] like Figures 1 to 6 As shown, in the embodiment of the present invention, the lower side wall 3 of the water inlet cover 100 is an inclined surface that gradually tilts downward from the back to the front, or a curved surface that gradually bends downward.
