It should be noted that, the present invention does not limit the specific value of the second preset time, and those skilled in the art can set the second preset time according to the actual situation.
Further, in step S107, after the air conditioner starts to count up from the time when the power device 23 and the spraying member 12 are turned off, and the air conditioner is operated in the cooling mode for a third preset time, the power device 23 and the spraying member 12 are controlled to be turned on again, and at this time, a certain amount of condensed water is received again in the water storage member 22, which can meet the requirement of one-time spraying use of the spraying member 12, and the third preset time is equal to the first preset time, but it should be understood that the third preset time may be longer than the first preset time, and a person skilled in the art may set the third preset time by himself or herself according to actual conditions, and the setting in step S107 enables the air conditioner to periodically remove dust from the outdoor heat exchanger 11.

Specifically, a water level sensor 221 is arranged in the water storage member 22, if the water level sensor detects that the water level in the water storage member 22 is higher than or equal to the preset water level, it is proved that the water storage member 22 is about to be full of water, and in order to avoid water from overflowing the water storage member 22, the controller 24 controls the power device 23 and the spraying member 12 to be opened so as to remove dust and cool the outdoor heat exchanger 11; if the water level sensor detects that the water level in the water storage member 22 is lower than the preset water level, the water level sensor proves that the amount of condensed water collected in the water storage member 22 cannot meet the requirement of one-time spraying use of the spraying member 12, and in order to ensure the spraying and dust removing effects of the spraying member 12, the controller 24 controls the power device 23 to be in a closed state as long as the water level in the water storage member 22 is lower than the preset water level; under the above situation, the spraying member 12 may be communicated with a water storage tank (not shown in the figures), the water storage tank is connected with a pump device (not shown in the figures), the pump device provides spraying pressure, water in the water storage tank can satisfy the requirement of the spraying member 12 for multiple spraying uses, and the water storage tank may be arranged indoors, so that a user can add water into the water storage tank conveniently.
In any of the above preferred embodiments, the air conditioner comprises the water storage tank and the pump device, and when the water in the water storage component 22 cannot satisfy the requirement of the spraying component 12 for one-time spraying use, the spraying component 12 can utilize the water in the water storage tank to perform spraying dust removal and spraying cooling.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
