When the air pressure in the water box 300 is greater than the air pressure of the water storage cavity 1010 of the water tank 1000, the second control valve 700 is opened, so that the inner cavity of the water box 300 communicates with the water storage cavity 1010 of the water tank 1000, and the liquid in the water box 300 can be discharged into the water storage cavity 1010 of the water tank 1000.
[0151] In some embodiments, the water tank 1000 can be arranged at one side of the inner container 100 along the width direction. The width direction is the direction indicated by the X-axis in the figure. Figure 2
[0152] In other embodiments, the water tank 1000 can be arranged at the back of the inner wall. The back is the side of the inner container 100 away from the door body.
[0153] In some embodiments, a breather is further included.
[0154] The breather is arranged in the mounting cavity, and the water box 300 is arranged in the breather.
[0155] It should be noted that the main function of the breather (also known as an air gap or air valve) in the dishwasher is to prevent sewage from flowing back into the dishwasher, thereby protecting clean tableware and the dishwasher itself. Specifically, the breather introduces an air gap in the drainage system of the dishwasher, ensuring that the sewage in the drain pipe 900 will not flow back into the dishwasher due to pressure difference or siphon effect. This can effectively prevent pollution and odor, and also meet health standards and building codes. In addition, the breather can also help regulate the pressure inside the dishwasher, ensuring smooth operation of the washing and draining processes. By maintaining proper air circulation, the breather can improve the overall performance and efficiency of the dishwasher.
[0156] It can be understood that the water box 300 is integrated with the breather, which is beneficial to save space.
[0157] In some embodiments, the vacuum pump 500 is arranged above the water box 300.
[0158] It can be understood that the vacuum pump 500 is located above the water box 300, and the water in the water box 300 is not easy to flow into the vacuum pump 500.
[0159] Figure 9 A structure diagram of a water tank and a filter in a dishwasher provided by an embodiment of the present application is shown in the drawings, Figure 10 For Figure 9 A local enlarged view at C in the dishwasher.
[0160] Referring to Figure 9 And Figure 10 As shown in the drawings, in some embodiments, the filter 1100 is further included.
[0161] The bottom of the water tank 200 is provided with a water outlet end 210, the filter 1100 is arranged on the top of the water outlet end 210, and the water outlet end 210 is connected with the water box 300.
[0162] It can be understood that the water outlet end 210 is arranged at the bottom of the water tank 200, thereby facilitating the complete drainage of water.
[0163] Moreover, by arranging the filter 1100, the residue in the water tank 200 can be effectively prevented from entering the vacuum pump 500 and damaging the vacuum pump 500. Meanwhile, the filter 1100 arranged on the water outlet end 210 facilitates the user to observe the state of the filter 1100 from the inner container 100 and clean the residue in time.
[0164] In some embodiments, the filter 1100 is arranged integrally with the water tank 200.
[0165] In some embodiments, the filter 1100 includes a plurality of filter holes arranged at intervals, and the filter holes are arranged on the water outlet end 210.
[0166] In some embodiments, the filter 1100 can be a filter screen.
