Thus, when the air pressure in the water tank 2 is reduced by injecting the water in the water tank 2 into the water tank 2 of the liner assembly 1, the air from the outside can enter the water tank 2 through the air inlet pipe 25, thereby balancing the air pressure inside and outside the water tank 2 to ensure that the water in the water tank 2 can smoothly flow to the liner assembly 1.

Advantageously, the water level detecting device 24 is disposed in the water outlet chamber 202 of the water tank 2, and the water level detecting device 24 can be used for detecting the water level in the water tank 2, thereby improving the automation degree of the dishwasher 100, facilitating real-time monitoring of the water level in the water tank 2, for example, when the water level detecting device 24 detects that the water level in the water outlet chamber 202 reaches a predetermined water level, a signal can be fed back to a control component, and the control component can control to stop filling water into the water outlet chamber 202.

In some embodiments of the present invention, the dishwasher 100 may further include a blower anti-siphon assembly 4, and the blower anti-siphon assembly 4 may include: the body part 41 has a water flow passage 412 and a balance passage 411 therein, one end of the water flow passage 412 (e.g., the left end of the water flow passage 412 shown in fig. 11) is connected to the outlet of the drain pump 6, and the other end of the water flow passage 412 (e.g., the right end of the water flow passage 412 shown in fig. 11) is used for drainage, when the dishwasher 100 drains water, the drain pump 6 operates, and water in the liner assembly 1 enters the water flow passage 412 through the drain pump 6 and is discharged (e.g., drained to a drain) through the water flow passage 412. Further, the balancing channel 411 may be connected to the water flow channel 412, and the balancing channel 411 has a vent 4114, and the vent 4114 is used to balance the internal and external air pressure of the water flow channel 412.

Advantageously, as shown in fig. 11, a check valve 4118 is disposed in the balance channel 411 for unidirectional communication of the air flow in a direction toward the water channel 412 (e.g., a top-down direction as shown in fig. 11), the check valve 4118 is disposed between the air vent 4114 and the water channel 412, and the check valve 4118 can effectively prevent water in the water channel 412 from entering the balance channel 411 to prevent siphoning.

In some embodiments, as shown in fig. 11, the water flow channel 412 may have a U-shape, one open end of the U-shape channel (e.g., the water flow channel inlet 4121 shown in fig. 11) is connected to the outlet of the drain pump 6, and the other open end of the U-shape channel (e.g., the water flow channel outlet 4122 shown in fig. 11) is used for drainage, and the balance channel 411 is connected to the upper portion of the water flow channel 412. When the drain pump 6 works, the drain pump 6 pumps out water in the liner assembly 1, the water enters the water flow channel 412 through the opening end on the left side of the water flow channel 412, then is discharged to a sewer from the opening end on the right side of the water flow channel 412, and the air pressure in the water flow channel 412 can be balanced through the vent 4114 arranged at the top of the balancing channel 411, so that the siphon phenomenon caused by the too low air pressure in the water flow channel 412 is avoided.

Advantageously, at least a portion of the equalization channel 411 may be in communication with and extend upwardly from a side of an upper portion of the water channel 412 proximate to the outlet (e.g., an upper portion of the right side of the water channel 412 as viewed in fig. 11). Therefore, the siphon phenomenon can be further avoided, water in the water flow channel 412 is prevented from entering the balance channel 411, and the air pressure balance effect of the balance channel 411 on the water flow channel 412 can be realized.

Since the balance channel 411 is connected to the water channel 412, water in the water channel 412 inevitably enters the balance channel 411 during the draining process of the drain pump 6, therefore, preferably, the balance channel 411 may be connected to the inner space of the liner assembly 1 for water return, so that water entering the balance channel 411 may flow back into the inner space of the liner assembly 1, thereby avoiding water accumulation in the balance channel 411, and ensuring that the balance channel 411 can effectively balance the air pressure in the water channel 412.

Further, as shown in fig. 11, the equalization channel 411 may include: the first vertical limb 4111, the second vertical limb 4112, and the horizontal limb 4113, the first vertical limb 4111 may extend in an up-down direction (e.g., up-down direction as shown in fig. 11), and a lower end of the first vertical limb 4111 communicates with the water flow passage 412, and a lower end of the first vertical limb 4111 communicates with an upper end of the water flow passage 412; the second vertical limb 4112 may also extend in the up-down direction, and the lower end of the second vertical limb 4112 is connected to the inner space of the liner assembly 1; the horizontal limb 4113 extends horizontally and communicates with the upper end of the first vertical limb 4111 and the upper end of the second vertical limb 4112, respectively. For example, the upper end of the first vertical limb 4111 is connected to and communicates with the right end of the horizontal limb 4113, and the upper end of the second vertical limb 4112 is connected to and communicates with the left end of the horizontal limb 4113, so that when water in the water flow channel 412 enters the horizontal limb 4113 through the first vertical limb 4111 due to the siphon phenomenon, the water can flow into the liner assembly 1 through the second vertical limb 4112, thereby making the structure of the balance channel 411 simpler and more reasonable, and also being convenient for manufacturing.

Advantageously, the bottom wall of the horizontal limb 4113 may be configured to slope downwardly in a direction from the first vertical limb 4111 to the second vertical limb 4112 (e.g., right-to-left direction as shown in fig. 11) such that when water enters the horizontal limb 4113, the water automatically flows along the downwardly sloped bottom wall to the second vertical limb 4112, thereby effectively draining the water within the equalization channel 411.

In some embodiments, as shown in fig. 11, baffles 4116 sloping downward relative to the free end in the horizontal direction are attached to each of the opposite side walls in the second vertical limb 4112, and the baffles 4116 on the opposite side walls in the second vertical limb 4112 are staggered into a circuitous path. For example, the baffles 4116 attached to the left side wall of the second vertical leg 4112 extend obliquely downward and rightward, the baffles 4116 attached to the right side wall of the second vertical leg 4112 extend obliquely downward and leftward, and the baffles 4116 attached to the left side wall and the right side wall of the second vertical leg 4112 are staggered in the up-down direction, and when water flows from the horizontal leg 4113 to the second vertical leg 4112, the baffles 4116 in the second vertical leg 4112 can have an effect of guiding the water flow so that the water flow quickly flows to the liner assembly 1. In addition, when the fan 42 in the fan anti-siphon assembly 4 works, part of the air flow in the air supply channel 413 leaks into the balance channel 411, and at this time, the staggered baffles 4116 extending obliquely downwards can effectively block the air flow from flowing through the balance channel 411, so that the efficiency of the fan 42 can be improved, and the leakage amount of the air flow can be reduced.

Since air generally flows at an upper level than water, in order to effectively balance the air pressure in the water flow channel 412, the vent 4114 in the balance channel 411 may be provided at the top of the balance channel 411, in particular, the vent 4114 may be formed at the top wall of the horizontal limb 4113, further, the top surface in the horizontal limb 4113 may be provided with a water blocking rib 4115, the water blocking rib 4115 being connected to the side of the vent 4114 adjacent to the first vertical limb 4111 (e.g., the right side of the vent 4114 as shown in fig. 11), and the water blocking rib 4115 may be used to block the water in the horizontal limb 4113 from flowing out through the vent 4114. Advantageously, the projection of the water barrier 4115 may completely cover the projection of the vent 4114 on the horizontal projection plane to enhance the water barrier effect thereof.

In some embodiments, the water blocking rib 4115 may be L-shaped, and in combination with fig. 11, the water blocking rib 4115 is connected to the right side of the vent 4114, and the water blocking rib 4115 is flush with the right side edge of the vent 4114, the water blocking rib 4115 is L-shaped, and the horizontal extension section of the water blocking rib 4115 is opposite to the vent 4114, and completely blocks the vent 4114.
