As shown in fig. 1, the water pan for the evaporator of the present embodiment includes a pan body 1, and a drain opening is disposed at the bottom of the pan body 1 and is used for connecting a sewer pipe 2. A vertical pipe body 3 is arranged in the tray body 1, the lower end of the pipe body 3 is a pipe opening, and the upper end of the pipe body is a pipe end. The pipe orifice at the lower end of the pipe body 3 is butted and fixed at the position of the lower water port, and the pipe orifice at the lower end of the pipe body 3 surrounds the lower water port. The position that the pipe end of body 3 upper end was avoided the center is equipped with a plurality of exhaust holes, and body 3 left side wall lower extreme position is equipped with the inlet opening and is used for communicating inside 1 of disk body, and body 3 right side inner wall lower extreme is equipped with a step portion 4.

The floating plate 5 and the ferromagnetic plate 6 are arranged in the pipe body 3, the floating plate 5 is arranged on the step part 4, so that the floating plate 5 is suspended above the lower water gap, and the ferromagnetic plate 6 is fixed on the floating plate 5. The external diameter of 5, the ferromagnetism boards 6 of kickboard matches with the internal diameter of jar body 3, and the circumference edge of 5, the ferromagnetism boards 6 of this kickboard keeps in contact with the inner wall of body 3.

In this embodiment, can set up a plurality of vertical fins as vertical slip guiding mechanism at the inner wall of body 3, the circumference edge of kickboard 5, ferromagnetism board 6 sets up the notch and is used for blocking on the fin, retrains kickboard 5, ferromagnetism board 6 through the fin, makes kickboard 5, ferromagnetism board 6 can only be in body 3 vertical lift.

A spring 7 is connected between the end position of the inner pipe of the pipe body 3 and the ferromagnetic plate 6, and when the floating plate 5 is arranged on the step part 4, the spring 7 is in a stretching or natural state.

An electromagnet 8 is fixed at the top of the pipe end of the pipe body 3, one magnetic pole of the electromagnet 8 faces downwards vertically, and the action range of magnetic attraction generated when the electromagnet 8 is electrified covers the vertical height of the pipe body 3. The electromagnet 8 is used for generating magnetic attraction force on the ferromagnetic plate 6 when being electrified.

A liquid level switch 9 is fixedly mounted on one side of the tray body 1, and the position of the liquid level switch 9 is higher than the initial floating plate 5, namely higher than the position of the floating plate 5 when the step part 4 is arranged. The electromagnet 8 is connected to a power source 10 via a level switch 9 to form a circuit, as shown by the dashed line in fig. 1.

In the initial state, the floating plate 5 is placed on the step portion 4, and therefore the floating plate 5 is suspended above the sewer, so that normal drainage is not hindered, and when water enters the tray body 1, water flow enters the bottom area in the pipe body 3 below the floating plate 5 from the water inlet hole at the lower end of the left side wall of the pipe body 3 and is discharged after falling into the sewer from the sewer.

As shown in fig. 2, when the fine dust particles 11 are accumulated in the downcomer 2, the drainage speed of the downcomer 2 is slowed, the accumulated water 12 is present in the tray body 1, and the liquid level of the accumulated water 12 continuously rises. The liquid level in the tube body 3 also rises along with the liquid level, at the moment, the floating plate 5 drives the ferromagnetic plate 6 to rise along with the rise of the liquid level, and the electromagnet 8 does not work because the liquid level does not reach the position of the liquid level switch 9 at the moment.

As shown in fig. 3, when the liquid level of the accumulated water 12 rises to the position of the liquid level switch 9, the liquid level switch 9 is turned on, the electromagnet 8 is powered to generate magnetic attraction force on the ferromagnetic plate 6, the magnetic attraction force enables the ferromagnetic plate 6 and the floating plate 5 to rise rapidly and separate from the liquid level at the moment, the ferromagnetic plate 6 and the floating plate 5 are compressed when rising integrally, the ferromagnetic plate 6 and the floating plate 5 move in a piston cylinder equivalently to the piston when rising in the pipe body 3, the ferromagnetic plate 6 and the floating plate 5 extrude the air in the rising path to be discharged from the exhaust hole at the pipe end of the pipe body 3, and then a negative pressure space a is formed between the liquid levels at the moment in the floating plate 5 and the pipe body 3. The ferromagnetic plate 6 and the floating plate 5 are lifted to a position where the spring 7 is compressed to the minimum, and then the lifting is stopped.

As shown in fig. 4, since the negative pressure space a is formed, on one hand, the accumulated water in the disk body 1 rapidly enters the negative pressure space a under the action of the pressure difference between the ambient air pressure and the negative pressure of the negative pressure space a; on the other hand, the water in the downcomer 2 backflushs into the negative pressure space A under the action of the pressure difference between the ambient pressure and the negative pressure of the negative pressure space A, and the fine dust particles 11 can be dispersed by utilizing the backflush water flow in the downcomer 2 to impact the collected fine dust particles 11. When water enters the negative pressure space A, a liquid column is formed.

When accumulated water in the disc body 1 enters the negative pressure space A, the liquid level in the disc body 1 is lowered, the liquid level switch 9 is disconnected again, and the electromagnet 8 loses the magnetic attraction force again. At this time, the floating plate 5 moves downward under its own weight (including the weight of the ferromagnetic plate 6) and the elastic force of the spring 7 until the floating plate 5 contacts the uppermost end of the liquid column formed in the negative pressure space a. Since the negative pressure space a is filled to form a liquid column which is higher than the liquid level in the tray body 1 and far higher than the position of the downcomer 2, the liquid column falls again, and the floating plate 5 also falls. When the liquid column falls, on one hand, water returns to the disc body 1 again, on the other hand, water is flushed into the sewer pipe 2, and at the moment, the water flow flushed into the sewer pipe 2 impacts the fine dust particles again, so that the fine dust particles can be taken away after being further dispersed. And the floating plate 5 is acted by the spring 7 when falling, so the falling of the floating plate 5 is equivalent to the movement of the piston, and the floating plate 5 applies force downwards to the liquid column, so that the water in the liquid column quickly enters the water receiving tray and the sewer pipe.

It can be seen that, the utility model discloses in based on body, kickboard isotructure, adopt a small amount of electronic parts, can realize not need not set up the controller in addition and control according to the function because of the automatic interior fine dust particle of sewer that breaks away of liquid level, also need not set up the force (forcing) pump and pressurize.
