In some embodiments, anti-siphon assembly 200 includes a door bench 201 and a check plate 202. As shown in fig. 3, the door frame 201 is provided on the inner wall of the ventilation channel 102, and the door frame 201 is located between the drain vent 1013 and the breathing port 1032. A check plate 202 is rotatably provided in the gas communication passage 102, and the check plate 202 is located on a side of the door sill 201 facing the drain vent 1013, the check plate 202 having an open position in which the check plate 202 is fitted on the door sill 201 to block the gas communication passage 102 and a closed position in which the check plate 202 has an air gap with the door sill 201 to communicate air.

During the normal drainage process of the dishwasher, sewage enters the drainage channel 101 to be split, a part of sewage flows to the sewage outlet 1012 to be discharged, and the other part of sewage enters the air connecting channel 102. Since check 202 is always in the closed position during normal draining, door sill 201 restricts the rotation of check 202 toward the side near door sill 201 because check 202 is located on the side of door sill 201 toward drain vent 1013. That is, when the water level of the sewage in the channel thereof is continuously raised and contacts the check sheet 202, under the dual actions of blocking of the check sheet 202 by the door bench 201 and the water pressure, the check sheet 202 is tightly attached to the door bench 201 to block the air connecting channel 102, so that the sewage cannot flow into the air chamber 103 to the breathing port 1032. Therefore, when the dishwasher discharges water normally, sewage cannot be discharged out of the respirator 1000 through the breathing port 1032.

When negative pressure occurs upstream of the drainage channel 101, since the air pressure in the drainage channel 101 is lower than the external atmospheric pressure, the check piece 202 is rotated in a direction away from the doorsill 201 by the external pressure, so that an air gap is formed between the check piece 202 and the doorsill 201 to circulate air. Therefore, the pressure difference in the drainage channel 101 can be balanced, and the sewage in the drainage channel 101 is prevented from flowing back.

Referring to fig. 3, the anti-siphon assembly 200 further includes a door shaft 203, the door shaft 203 is disposed on the door platform 201, the check sheet 202 is provided with a door hole 2021, and the door hole 2021 is sleeved on the door shaft 203. This makes it possible to rotate the check plate 202 with respect to the door mount 201, and the structure is very simple. The aperture area of the door aperture 2021 is larger than the cross-sectional area of the part of the door shaft 203 located in the door aperture 2021, and the rotation direction of the check flap 202 is perpendicular to the extension direction of the door shaft 203. Therefore, the check sheet 202 can be enabled to rotate under the action of external pressure, so that a gap is formed between the check sheet 202 and the door frame 201 to circulate air. The door hole 2021 is formed in a rectangular shape, and the door shaft 203 is formed in a rectangular parallelepiped shape. The free end of the door shaft 203 is provided with a snap (not shown). This prevents the check plate 202 from being rotated excessively by the external pressure to disengage the check plate 202 from the door shaft 203. The snap is formed as a nut, and after the check plate 202 is fitted on the door shaft 203, the nut is fitted on the door shaft 203 with a certain distance between the nut and the check plate 202. Of course, the snap projection may be formed in other configurations such as a snap ring, etc.

An enclosing edge 204 is arranged on the side of the check sheet 202 facing the drainage vent 1013 in the air connecting channel 102. It will be appreciated that when the check tab 202 is applied to the doorsill 201, one side of the check tab 202 abuts against the peripheral edge 204. This is advantageous in ensuring the sealing between the check piece 202 and the door 201 in the closed position so that the waste water is not discharged from the air communicating passage 102 when the dishwasher is normally drained. Specifically, a peripheral edge 204 is formed below the check sheet 202. The check sheet 202 is formed as a flat plate and is a piece of rubber material. Such a configuration is relatively simple, cost effective, and provides a good shut off of the communication passage 102 when the check plate 202 is in the closed position.

It will be appreciated that in practice, when the check sheet 202 of the anti-siphon assembly 200 is engaged with the door table 201, there is no guarantee that there is no gap between the check sheet 202 and the door table 201, i.e. the check sheet 202 and the door table 201 cannot be completely sealed. Thereby the setting of water conservancy diversion passageway can avoid effectively flowing into the sewage in the air chamber 103 through the clearance between check piece 202 and the door plant 201 and pass through the dish washer of breathing port 1032 discharge, and then has improved respirator 1000's reliability, has guaranteed the security performance of dish washer, has promoted user's use impression simultaneously.
