[0042] (Embodiment 1)

[0043] As Figures 1-2As shown, the laundry machine door cover assembly provided by the embodiment of the present application comprises a door cover base 1, a door cover 2, a water box 3, and a dispensing valve 4. The door cover 2 is arranged on the door cover base 1, and the door cover has a cavity for accommodating a laundry treatment agent pair. The cavity is provided with an injection port for injecting the laundry treatment agent into the cavity and a liquid discharge port for discharging the laundry treatment agent in the cavity. The injection port and the liquid discharge port are opened on the door cover.

[0044] The door cover base is provided with the water box 3 and the dispensing valve 4. Specifically, the door cover base 1 is part of the laundry machine door cover assembly, and the outer contour of the door cover base 1 matches the upper opening of the washing tub of the laundry machine, so that the door cover base 1 can be connected to the laundry machine in an openable and closable manner. The overall laundry machine door cover assembly becomes the cover of the laundry machine. The door cover 2 is fixed to the door cover base 1, and is preferably pivotally connected to the door cover base and serves as the door of the laundry machine together with the door cover base 1, for opening and closing the dispensing port of the laundry machine.

[0045] The cavity 21 is provided with a cavity cover 22 and a cover body 23. The cavity cover 22 is covered on the cavity 21 to form a sealed cavity for containing the laundry treatment agent. The cavity cover 22 is provided with an injection port for injecting the laundry treatment agent, and the cover body 23 is detachably covered on the injection port.

[0046] In combination Figure 3 , Figure 9 As shown, the cover body 23 is provided with an air hole 14, and a one-way piece 24 is arranged on the air hole for preventing the laundry treatment agent from leaking when the cover body 23 is opened. Preferably, the one-way piece is an elastic body, such as a rubber one-way piece. When the dispensing valve is opened, the detergent flows out under the action of gravity. At this time, the one-way piece is bent and deformed under the pressure of the detergent to open the air hole. When the dispensing valve is not opened, the one-way piece is pressed on the air hole 14 to seal the air hole.

[0047] Specifically, the one-way piece can be optimized to include a head portion 12-1, a tail portion 12-3, and a connecting portion 12-2 between the head portion and the tail portion. The head portion is used to fix the one-way piece, and the tail portion is used to block the air hole. When the dispensing valve is not opened, the air pressure in the internal containing cavity of the door cover assembly is balanced, and the tail portion blocks the air hole to make it in a sealed state. When the dispensing valve is opened, the washing liquid in the door cover assembly flows downward, the air pressure in the cavity decreases to be less than the atmospheric pressure, and the tail portion deforms under the atmospheric pressure to generate a gap to compensate the gas and balance the pressure in the cavity.

[0048] The tail portion in the embodiment achieves the sealing and communication of the air hole by deformation. The thickness A of the tail portion is designed in combination with the maximum and minimum values of the capacity of the detergent, and a thickness of 20-24 mm is recommended. Too thick thickness will cause the door cover to be too heavy, and a thickness of 20 mm can reach a capacity of 1.2 L, which meets the multiple washing use of users.

[0049] Specifically, the corresponding thickness of the single-sided sheet can be selected according to the following correspondence. The capacity in the table refers to the maximum value of the detergent capacity.

[0050] Thickness A (mm) 20 22 24 26 28 Volume (L) 1.22 1.36 1.53 1.67 1.81
