Take the dishwasher shown in Figures 1 to 10 as an example to illustrate the specific working process of the residual liquid treatment mechanism:

When the dishwasher works normally, the washing chamber and the receiving chamber of the cup body are filled with washing water, and the movable part is in a closed state at this time, and the sealing part 42 on the movable part cuts off the receiving chamber 201 and the liquid discharge chamber 202 ; Pass positive electricity to electromagnet 52 to generate magnetic field, produce downward attractive force to permanent magnet 51, movable part relies on electromagnet 52 to produce downward attractive force to permanent magnet 51, and under the gravity of movable part itself, remain closed.

When starting to drain water, the electromagnet 52 is energized in reverse to change the magnetic field direction of the magnetic field generated by the electromagnet 52, and an upward repulsive force is generated on the permanent magnet 51, so that the movable part moves away from the liquid discharge chamber, and the movable part is in In the open state; at the same time, the solution in the accommodation chamber enters the groove 440, producing a buoyancy force towards the main body 41 away from the transition chamber 203. Drainage is carried out under the action of the suction force of the drainage pump. At this time, the movable part 4 relies on the magnetic force and buoyancy between the permanent magnet part 51 and the electromagnetic part 52 to ensure that the position of the movable part 4 will not be changed due to the suction force brought by the operation of the drainage pump and affect drainage; When the water level is lower than the movable part 4, the movable part 4 will decrease with the drop of the water level. After the water flow in the cup body 2 is completely discharged and before the washing pump is finished, there is no buoyancy effect at this time, and the movable part 4 is under the action of the electromagnetic force. Keep the open state for a certain period of time and then close, that is, it has a delayed closing function, which avoids the situation that part of the water flow cannot be drained in time due to other reasons; , there is no buoyancy effect at this time, that is, the movable part 4 is closed relative to the cup body 2 by its own gravity, after the movable part 4 is closed relative to the cup body 2, the upper end of the electromagnetic part 52 is aligned with the permanent magnet The lower end magnetic pole of part 51 is opposite, produces downward attractive force to movable part 4, further strengthens this closed state, and the water of anti-siphon backflow is enclosed in the drainage waterway, can not flow back in the washing chamber 10. Because after the solution in the washing chamber 10 is discharged, the movable part 4 moves and is in a closed state, that is, the accommodating chamber 201 and the liquid discharge chamber 202 are cut off, even if the anti-siphon structure sucks air and does not suck the liquid in the liquid discharge chamber 202 At this time, the residual solution is intercepted in the draining chamber 202, and will not flow back into the accommodating chamber 201 to enter the washing chamber 10, thereby ensuring that there is no liquid remaining in the washing chamber 10, thereby avoiding the breeding of bacteria in the washing chamber 10 and produce odors.

Further, the movable part 4 includes a main body 41 and a sealing part 42 disposed on the main body 41 , and the sealing part 42 is distributed facing the transition cavity 203 . In the closed state, the main body portion 41 covers the end face of the inlet end or the end face of the outlet end of the transition chamber 203, and the sealing portion 42 is clamped between the main body portion 41 and the end face of the inlet end or the end face of the outlet end of the transition chamber 203 to realize the transition. The cavity 203 is sealed, so that the accommodating cavity 201 and the liquid discharge cavity 202 are cut off. On the contrary, in the open state, the main body portion 41 and the sealing portion 42 rotate to avoid the inlet end or the outlet end of the transition chamber 203 to communicate with the accommodating chamber 201 and the liquid discharge chamber 202 .
