[0002] The fresh air system with the electrostatic precipitator filter can send the outdoor air into the room through the air supply port of the fresh air system after the haze removal and purification. , the plate of the electrostatic precipitator filter absorbs too much dust and needs to be cleaned, the outdoor humidity is too high or equipment failures and other reasons may cause the plate of the electrostatic precipitator filter to fail to transmit power and stop working. Once the electrostatic precipitator filter stops working, the user It is difficult to accurately determine the cause, and it is even more difficult to take correct operations to restore the normal operation of the electrostatic precipitator filter. Therefore, the fresh air system in the prior art is very inconvenient to use, and it is easy to cause unnecessary waste of energy and resources

Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] figure 1 It shows an embodiment of the control method for passively cleaning the electrostatic precipitator filter of the haze removal fresh air system of the present invention, the haze removal fresh air system includes a humidity sensor 9, a control device 10, an air supply pipe 3, an air supply fan 5, an electrostatic precipitator The filter 7 and the bypass fresh air pipe 8, and the electrostatic precipitator filter 7 are equipped with an automatic cleaning function. When the electrode plate of the electrostatic precipitator filter 7 is short-circuited in the haze removal fresh air system, the electrostatic precipitator filter 7 will be passively cleaned , including the following steps:
[0040] S100: Detect the outdoor humidity φ;
[0041] S200: The maximum humidity setting value is φ1, if φ≤φ1, then enter step S300, if ...

The invention discloses a control method and system for a passive washing electrostatic dust removing filter of a haze eliminating fresh air system. The method includes the following steps that S100, the outdoor humidity phi is detected; S200, the maximum humidity set value is phi 1, if phi is smaller than or equal to phi 1, the step S300 is executed, and if phi is larger than phi 1, the step S201 is executed; S300, the electrostatic dust removing filter is turned on for automatic washing; S400, after washing is finished, power is supplied to a counter electrode of the electrostatic dust removing filter; S500, if the electrostatic dust removing filter can be turned on, the step S600 is executed, and if the electrostatic dust removing filter cannot be turned on, the step S501 is executed; and S600, the electrostatic dust removing filter starts to work normally. A short circuit of the counter electrode can be automatically judged and corresponding control operation is performed, so that the haze eliminating fresh air system is used more conveniently. The system comprises a humidity sensor and a control device. The humidity sensor is arranged outdoors and connected with the control device. The control device is connected with a three-way electromagnetic switching valve and a control valve of the electrostatic dust removing filter. The control method can be reliably and effectively implemented.
