When the air conditioner 10 and the filtering mechanism are used, the evaporator 100 is disposed above the water receiving tray 300, and when the evaporator 100 is used, condensed water is generated, so that the condensed water can effectively drop into the water receiving tray 300. Since the filter member 410 of the filter assembly 400 is covered on the first tuyere 210 of the housing 200, the air introduced into the housing 200 or the air discharged from the first tuyere 210 can be filtered by the filter member 410. When the filter 410 needs to be cleaned, the controller controls the drain valve at the drain port 310 of the water receiving tray 300 to be closed, so that condensed water can be collected in the water receiving tray 300. The driving part 420 is further controlled to operate by the controller, the driving part 420 is used for driving the filtering piece 410 to pass through the space in the water receiving tray 300, and the condensed water gathered in the water receiving tray 300 is used for cleaning the filtering piece 410, so that the purpose of cleaning the filtering piece 410 is realized. After the washing is finished, the controller controls the drain valve to open, so that the condensed water in the water receiving tray 300 can be drained through the drain port 310.

Furthermore, in the process of cleaning the filter element 410, the filter element 410 does not need to be disassembled, and the cleaning process does not need to add water into the filter mechanism, so that the cleaning process is convenient.

In this embodiment, the first cleaning signal can be understood as being started, and if the first cleaning signal is not obtained, the devices such as the water level detection part and the driving part 420 are kept in the power-off state, so that the waste of electric energy caused by the fact that the devices such as the water level detection part and the driving part 420 are in the standby state can be avoided. After the first cleaning signal is acquired, the water level detecting element, the driving element 420 and other elements are powered on to be in a standby state or a starting state. In other embodiments, the first cleaning signal may be a cleaning signal for triggering the cleaning filter 410, and the water level detecting member, the driving member 420, and the like are in a standby state.

In one embodiment, step S120: after the step of controlling the closing of the drain valve, the method further comprises the following steps:

step S140: acquiring a water level signal in the water pan 300; by acquiring the water level signal in the water receiving tray 300, the water level in the water receiving tray 300 can be conveniently judged.

The trigger drive 420 drives the filter element 410 through the space within the drip tray 300.

Specifically, a water level signal in the drip tray 300 is acquired by a water level detector in the drip tray 300. The water level detector can be arranged at a preset water level of the water pan 300, and when the condensed water in the water pan 300 reaches the preset water level, the water level detector can be triggered to feed back a water level signal to the controller, so that the controller controls the driving part 420 to operate.

In this embodiment, the preset water level is higher than or equal to the water level that can be lower than the filtering member 410 positioned in the water tray 300, so that the cleaning effect of the filtering member 410 can be ensured. When the water level in the water receiving tray 300 reaches a preset water level, the driving member 420 is controlled to drive the filtering member 410 to pass through the space in the water receiving tray 300, so as to clean the filtering member 410.

In other embodiments, step S120: after the step of controlling the closing of the drain valve, the method further comprises the following steps:

step S140: acquiring a water level signal in the water pan 300;

if the water level signal is greater than or equal to the predetermined water level signal, step S130 is performed.

Acquiring a water level signal in the water receiving tray 300 in real time through a water level detection piece in the water receiving tray 300, transmitting the water level signal to a controller, judging whether the acquired water level signal is greater than or equal to a preset water level signal or not through the controller, and if the water level signal is less than the preset water level signal, enabling the water level in the water receiving tray 300 not to reach the preset water level; if the water level signal is greater than or equal to the preset water level signal, the water level in the water tray 300 reaches the preset water level, and at this time, the driving member 420 is controlled to drive the filtering member 410 to move, so that the cleaning efficiency of the filtering member 410 can be improved.

In one embodiment, step S140: after the step of acquiring the water level signal in the water collector 300, the method further includes:

step S150: acquiring a second cleaning signal;

step S130: the driving member 420 is controlled to drive the filter member 410 through the space in the drip tray 300.

When the water level signal in the water receiving tray 300 is obtained, the water level in the water receiving tray 300 reaches the preset water level, and at this time, after the second cleaning signal is obtained, the driving member 420 is controlled to operate, and the driving filtering member 410 is driven to clean through the space in the water receiving tray 300. In this embodiment, since the first cleaning signal is the start signal, the second cleaning signal is obtained, so that the start of the driving member 420 is controlled conveniently, and the purpose of cleaning the filtering member 410 is achieved. In other embodiments, the step of acquiring the second cleaning signal may also be omitted.

In one embodiment, step S130: after the step of controlling the driving member 420 to drive the filtering member 410 through the space in the water tray 300, the method further includes:

step S160: when the driving member 420 runs for a preset time, controlling the driving member 420 to stop running;

step S170: and controlling the drainage valve to be opened.

After the driving member 420 operates for a preset time, the filtering member 410 is considered to be cleaned, the driving member 420 is controlled to stop operating, and the drain valve is opened, so that condensed water in the water pan 300 can be drained conveniently, and the condensed water is prevented from being continuously left in the water pan 300 to nourish bacteria.

In this embodiment, the step of electrically connecting the drain pump to the controller, and after the step of controlling the driving member 420 to stop operating after the driving member 420 operates for a preset time, further includes:

and controlling the starting of the drainage pump. The drainage efficiency of the condensed water in the water receiving tray 300 can be improved by the drainage pump, and bacteria breeding caused by residual water reserved in the water receiving tray 300 is avoided.

In this embodiment, the predetermined time is greater than or equal to the circumference of the filtering member 410 divided by the rotation speed of the filtering member 410, so as to ensure that different parts of the filtering member 410 can pass through the space in the water tray 300, thereby ensuring the cleaning effect of the filtering member 410.
