and when the operation mode is a water using working condition, the water diversion member (32) is controlled to be in a water diversion position.

16. The control method according to claim 15, wherein the operation mode corresponding to the water use condition comprises at least one of a heat exchanger cleaning mode, a fan blade cleaning mode, a drain pipe cleaning mode, a humidifying mode and a rapid heating mode.

17. The control method according to claim 16,

when the operation mode is a heat exchanger cleaning mode and the water level of condensed water in the water fetching area (311) reaches a first set height h1, controlling the lower axial flow fan blade (2) to rotate along a second rotary direction at a low speed and a high speed for a first preset time; alternatively, the first and second electrodes may be,

when the operation mode is a fan blade cleaning mode and the water level of condensed water in the water fetching area (311) reaches a second set height h2, controlling the lower axial flow fan blade (2) to rotate along a first rotation direction at a low speed and a high speed for a second preset time; alternatively, the first and second electrodes may be,

when the operation mode is a drain pipe cleaning mode and the water level of condensed water in the water beating area (311) reaches a third set height h3, the lower axial flow fan blade (2) is controlled to be static and the water diversion piece (32) is controlled to be at a discharge position.

18. The control method according to claim 16,

when the operation mode is a humidification mode and the water level of condensed water in the water fetching area (311) reaches a fourth set height h4, controlling the lower axial flow fan blade (2) to rotate alternately along a second rotary direction at a low speed and a high speed for a third preset time, and then controlling the air conditioner to operate in a refrigeration or heating mode; alternatively, the first and second electrodes may be,

when the operation mode is a rapid heating mode and the water level of condensed water in the water fetching region (311) reaches a fifth set height h5, the lower axial flow fan blade (2) is controlled to rotate along the second rotation direction at low and high speed for a fourth preset time period in an alternating mode, and then the air conditioner is controlled to operate in the heating mode.

19. The control method according to claim 16,

when the operation mode is the water consumption condition and the water diversion piece (32) is located at the water diversion position, acquiring the temperature and the humidity of the current environment;

when the acquired temperature and humidity of the current environment are lower than the target temperature and humidity, prompting a user to inject water into the water fetching area (311); and/or controlling the water diversion member (32) to be in the water drainage position after the operation of each operation mode corresponding to the water use working condition is finished.
