It can be understood that the turbidity sensor 300 according to the present invention is used to detect the degree of turbidity of the water in the first water outlet pipe 200 to determine whether the filter screen is cleaned. Among other things, the turbidity sensor 300 can emit light for passing through a certain amount of water, and the amount of light transmission depends on the degree of turbidity of the water. The more dirty the water, the less light passes through, and conversely the more light passes through. The turbidity sensor 300 has a light receiving end for receiving light transmitted through water and converting light intensity into a corresponding current magnitude. The more light that is transmitted, the larger the current tends to be, and vice versa. The turbidity sensor 300 determines the degree of water turbidity based on the magnitude of the current generated at its light receiving end. The invention can generate a voltage signal by passing the current generated by the light receiving end through the resistor during application, and can sample the voltage signal by using the analog-to-digital converter, so that the controller can know the current water pollution degree according to the sampling result.

Wherein the height of the low liquid level sensor 700 is smaller than the height of the middle liquid level sensor 701, and the height of the middle liquid level sensor 701 is smaller than the height of the high liquid level sensor 702. The level sensor may be, for example, a tuning fork level sensor. More specifically, the low level sensor 700 of the present invention may be used to determine whether the water in the cleaning water tank 101 has been drained, the middle level sensor 701 may be used to determine whether the water in the cleaning water tank 101 reaches a middle level, and the high level sensor 702 may be used to determine whether the water in the cleaning water tank 101 is overflowed.

The apparatus may also include a motion mechanism that may be used to drive the air conditioner screen into the cleaning tank 100.
As shown in fig. 2, and in conjunction with fig. 1 and 3, the present invention can provide a method for cleaning an air conditioner screen. The method can realize automatic cleaning of the air conditioner filter screen, and particularly, the method can comprise but is not limited to at least one of the following steps.
The air conditioner condensate water is recovered, the recovery process can be executed after the cleaning function is started or in advance, and the cleaning function can be started automatically or manually. And stores the air conditioner condensate in the condensate collection tank 102, and uses the air conditioner condensate as a cleaning agent.
The second suction pump 501 is controlled to operate, i.e., the air conditioner condensate is supplied to the wash water tank 101 through the condensate collection tank 102. The present invention may include supplying the air conditioner condensate to the wash water tank 101 through the condensate collection tank 102: it is determined whether to stop the supply of the air conditioning condensate water to the washing water tank 101 according to the liquid level in the washing water tank 101. Specifically, the present invention can store a proper amount of air conditioner condensate water in the cleaning water tank 101 through a predetermined program, and the manner of detecting the liquid level in the cleaning water tank 101 may be to determine whether the proper amount of condensate water is appropriate by using a tuning fork liquid level sensor in the cleaning water tank 101, and the proper amount of condensate water may be not less than half of the total volume of the water tank (middle water level), for example, and may be detected by the middle liquid level sensor 701. It should be understood that the air conditioner condensed water of the present invention can be replaced by other liquid with a cleaning function as a cleaning agent based on the present disclosure. But the invention can utilize the air conditioner condensed water as the cleaning agent to realize the high-efficiency utilization of resources, thereby greatly improving the user experience while reducing the user input cost.
In specific implementation, the present invention can drive the filter screen of the air conditioner to be cleaned to enter the cleaning tank 100 through the moving mechanism. It should be understood that the motion mechanism of the present invention may be integrated into an air conditioning apparatus and may be automatically controlled by the purge control module 800.
The first suction pump 500 is controlled to be operated to supply the washing tub 100 with the air conditioner condensate water through the washing water tank 101 along the first water supply pipe 400 for connecting the washing water tank 101 and the washing tub 100. The cleaning cavity of the cleaning tank 100 is placed with an air conditioner filter screen to be cleaned, and the air conditioner filter screen is cleaned by using the air conditioner condensate water in the cleaning tank 100. It can be understood that the invention can control the movement of the filter screen or the movement of the condensed water of the air conditioner or the movement of both the filter screen and the condensed water of the air conditioner during the cleaning process, thereby improving the cleaning effect of the filter screen and reducing the cleaning time. Of course, the present invention may also be configured such that the air conditioner condensed water is first added to the cleaning tank 100, and then the air conditioner filter is placed in the cleaning tank 100. The first water pump can be controlled to work based on the condition that the detection result of the liquid level sensor in the cleaning water tank 101 reaches the set value, and the set value can be the condition that the air conditioner condensed water in the cleaning water tank 101 reaches half of the total volume of the water tank so as to convey the air conditioner condensed water in the cleaning water tank 101 to the cleaning cavity of the cleaning tank 100. Therefore, the invention can provide sufficient air conditioner condensate water for the air conditioner filter screen to be cleaned so as to meet the requirement of cleaning the air conditioner filter screen.
The air conditioner filter screen placed in the cleaning tank 100 is then cleaned by the air conditioner condensed water in the cleaning tank 100, and the cleaning process may be generally performed once or more times.
After the filter screen is cleaned, the sewage generated by cleaning flows out of the first water outlet pipe 200 below the cleaning tank 100. The present invention detects a turbidity value of the air-conditioned condensed water in the first outlet pipe 200 connected to the water outlet of the washing tub 100 using the turbidity sensor 300. It is understood that the present invention can correspond different turbidity value ranges to different turbidity levels, for example, the turbidity level is set to 0-10, "0" can be used to indicate clean, "10" can be used to indicate turbidity. Of course, the present invention can also operate accordingly based on the actual turbidity value detected.
And judging whether to stop cleaning the air conditioner filter screen or not according to the turbidity value of the air conditioner condensed water, wherein the filter screen cleaning can be completed when the filter screen cleaning is stopped, and one or more times of cleaning is needed when the filter screen cleaning is not stopped. The invention judges whether to continuously clean the air conditioner filter screen according to the turbidity value of the condensed water of the air conditioner, and stops cleaning the air conditioner filter screen when the turbidity value meets the set condition (which can be set according to the actual condition, such as the turbidity value is less than or equal to 7 ℃), otherwise (such as the turbidity value is greater than 7 ℃).
Under the condition of continuing to clean, namely in the process of continuously cleaning the air conditioner filter screen, whether the air conditioner condensed water flowing out of the first water outlet pipe 200 flows back to the cleaning water tank 101 is judged according to the turbidity value of the air conditioner condensed water. Specifically, the present invention can judge whether the current sewage discharge is the first discharge, and directly discharge the sewage to the outside through the sewage discharge pipe 201 at the first discharge. It is also possible to judge whether the change rate of the turbidity value satisfies the current setting condition when the discharge is not the first discharge. According to the invention, the air conditioner condensed water flowing out of the first water outlet pipe 200 can be refluxed into the cleaning water tank 101 based on the fact that the change rate of the turbidity value of the air conditioner condensed water is in the first set range, and the refluxed air conditioner condensed water is mixed with the condensed water extracted from the condensed water collecting tank 102, so that the utilization rate of the air conditioner condensed water can be improved. The first setting range may be, for example, 5 degrees or more per time (i.e., in the case where the currently discharged water is reduced by at least 5 degrees from the last turbidity value). It can be understood that, under the condition that the turbidity value of the air-conditioning condensed water is within the second set range under the condition of continuous cleaning, the air-conditioning condensed water flowing out of the first water outlet pipe 200 flows back into the cleaning water tank 101, the returned air-conditioning condensed water is mixed with the condensed water pumped out of the condensed water collection box 102, and the mixed water can play a role in continuously cleaning the air-conditioning filter screen, so that the utilization rate of the air-conditioning condensed water can also be improved. The second setting range can be set according to actual conditions, and may be, for example, 10 degrees or less.
The three-way valve 600 provided on the first water outlet pipe 200 is controlled based on the condition that the turbidity value of the air-conditioning condensate is within the third setting range, so that the air-conditioning condensate is discharged along the three-way valve 600 and the drain pipe 201 connected to the three-way valve 600. The third setting range may be set according to actual conditions, and may be, for example, 20 degrees or more. The used water is turbid and has no value of secondary utilization, and the air conditioner filter screen may need to be cleaned for a plurality of times.
When the turbidity value detected by the turbidity sensor 300 satisfies the set condition, the cleaning of the air conditioner filter screen is stopped, that is, the cleaning of the air conditioner filter screen is completed. The invention can also drive the filter screen of the air conditioner to reset through the movement mechanism and automatically control the air conditioner to blow the filter screen. The invention can completely reflux the air conditioner condensed water flowing out of the first water outlet pipe 200 to the cleaning water tank 101 and drain the water in the cleaning water tank 101, thereby avoiding the corrosion of the cleaning tank 100 or the cleaning water tank 101 by the water, prolonging the service life of the product and ensuring better product reliability.
