The water draining process of the dishwasher 100 is: the washing soil generated in the first washing chamber enters the drain passage 51 through the soil inlet 511 and is then discharged into the first drain passage 31 through the soil outlet 512, thereby accomplishing a drain process of the dishwasher 100.
When the draining process is stopped, negative pressure is formed in the upstream section of the drain passage 51, so that water retained in the downstream section of the drain passage 51 communicating with the first drain passage 31 has a tendency to flow back due to siphoning, and air in the atmosphere can enter the drain passage 51 through the drain vent 513 due to the communication between the drain vent 513 and the atmosphere to balance the pressure difference in the drain passage 51, preventing siphoning phenomenon of the drain passage 51, thereby preventing water in the drain passage 51 from flowing back into the first washing chamber of the dishwasher 100 after draining, and ensuring smooth draining of water retained in the drain passage 51.
Since the first washing chamber of the dishwasher 100 is communicated with the air chamber 53 through the communication port 532, on one hand, water vapor in the first washing chamber will enter the air chamber 53 through the communication port 532, and water vapor condenses in the air chamber 53 to form droplets, on the other hand, when the water level in the first washing chamber of the dishwasher 100 is abnormal, water in the first washing chamber will enter the air chamber 53 through the communication port 532, thereby causing a portion of water to be stored in the air chamber 53, and when the water level in the air chamber 53 rises to a level higher than that of the breathing port 531, water entering the air chamber 53 overflows outwards through the breathing port 531, thereby causing a water leakage problem to occur in the dishwasher 100 and affecting the performance of the dishwasher 100.
In order to solve the above problem, the air chamber 53 of the respirator 50 of the present application is further provided with an overflow port 533, and it is understood that the overflow port 533 is located at a lower level than the breathing port 531, the overflow port 533 is adapted to be communicated with the second water drain channel 32, and when the water level in the air chamber 53 is higher than the overflow port 533, water in the air chamber 53 is discharged out of the air chamber 53 through the overflow port 533, and is further discharged through the second water drain channel 32, the first water drain channel 31 and the main water drain channel 34, thereby avoiding water leakage caused by too high water level in the air chamber 53.
According to the dish washer 100 provided by the embodiment of the invention, the pressures of the first washing cavity, the water drainage channel 51 and the water inlet cavity 52 and the atmosphere can be balanced, the pressure in the first washing cavity can be prevented from being overlarge when the dish washer 100 works, the safety of the dish washer 100 in the working process is ensured, the siphonage phenomenon in the water drainage channel 51 and the water inlet cavity 52 is avoided, meanwhile, the breather 50 can also provide reclaimed water for the water softener, in addition, the water entering the air cavity 53 can also be discharged through the overflow port 533, the breather 50 is prevented from leaking water, and the service life of the dish washer 100 is further prolonged.
