The aforementioned first rotation direction may, for example, be a reverse rotation.

[0045] As shown in the drawings, Figure 4 The water scooping structure 211 comprises a hook-shaped body, the hook of the hook-shaped body being concave inward and the side thereof facing the central area of the lower axial fan blade 2, so that a certain amount of condensed water can be accommodated in the hook of the hook-shaped body, and then the splashing cleaning of the lower axial fan blade 2 itself and the upper axial fan blade 1 can be realized by the high and low rotating speed of the lower axial fan blade 2, the structure being simple and convenient to manufacture.

[0046] In a preferred embodiment, the lower axial flow fan blade 2 further has a water pushing structure 212, which is capable of pushing the condensed water in the water hitting area 311 to the heat exchanger 4 adjacent to the lower axial flow fan blade 2 during the rotation of the lower axial flow fan blade 2 in the second rotation direction opposite to the first rotation direction, i.e. when the first rotation direction is the reverse rotation, the second rotation direction is the forward rotation. In this technical solution, the water pushing structure 212 pushes the condensed water in the water hitting area 311 to the heat exchanger 4 during the rotation of the lower axial flow fan blade 2 in the second rotation direction, so that the overall cleaning of the heat exchanger 4 in the height direction can be realized by controlling the high and low rotating speed of the fan blade, which is beneficial to improve the heat exchange efficiency of the heat exchanger 4 and ensure the heat exchange effect of the air conditioner.

Further, the water pumping structure 211 and the water pushing structure 212 are integrally formed to form a plurality of water hitting components, the plurality of water hitting components are arranged at intervals along the circumferential direction of the water hitting ring 21, so that the water pumping structure 211 and the water pushing structure 212 are integrally formed, which can simplify the manufacturing process.

[0049] Specifically referring to Figures 5 to 7As shown, the water receiving area 312 is provided below the heat exchanger 4, and the water striking area 311 is provided below the lower axial flow fan blade 2. The water receiving area 312 and the water striking area 311 are not necessarily adjacent to each other. The water receiving area 312 is connected to the water striking area 311 by the water guide member 32. The water guide member 32 is provided on the water pan body 31 and is connected to the water pan body 31. The water guide member 32 is provided with a water guide channel 322. The water guide channel 322 is provided with a blocking portion 3221. The blocking portion 3221 is provided on the outer side of the bottom wall of the water guide channel 322 and extends downward. The water pan body 31 is provided with a drain hole (not shown in the figure) which is connected to a drain pipe 62. When the water guide member 32 is in the water guide position, the blocking portion 3221 is inserted into the drain hole to block the drain hole. In this way, the condensed water collected in the water receiving area 312 can be prevented from being discharged, and the condensed water can be collected in the water striking area 311 in time.

[0050] As shown in the figure, the water pan assembly 3 is provided with a water pan body 31. The water pan body 31 is provided with a water receiving area 312 and a water striking area 311. The water pan assembly 3 is further provided with a water guide member 32. The water guide member 32 is provided with a water guide position which can guide the condensed water in the water receiving area 312 to the water striking area 311. Figure 6 As shown in the figure, the water pan assembly 3 is provided with a water pan body 31. The water pan body 31 is provided with a water receiving area 312 and a water striking area 311. The water pan assembly 3 is further provided with a water guide member 32. The water guide member 32 is provided with a water guide position which can guide the condensed water in the water receiving area 312 to the water striking area 311. Figure 7 As shown in the figure, the water guide member 32 is provided with a water guide channel 322. The water guide channel 322 is provided with a blocking portion 3221. The blocking portion 3221 is provided on the outer side of the bottom wall of the water guide channel 322 and extends downward. The water pan body 31 is provided with a drain hole (not shown in the figure) which is connected to a drain pipe 62. When the water guide member 32 is in the water guide position, the blocking portion 3221 is inserted into the drain hole to block the drain hole. In this way, the condensed water collected in the water receiving area 312 can be prevented from being discharged, and the condensed water can be collected in the water striking area 311 in time.

[0051] In some working conditions, the operation of the air conditioner does not need to use the condensed water. At this time, the condensed water needs to be discharged in time to prevent the condensed water from staying in the water pan for a long time to breed bacteria or even corrode the related components. Therefore, the water guide member 32 is further provided with a drain position which allows the drain hole to drain water. As an optional embodiment, the rotating driving member 33 is drivingly connected to the rotating shaft 321 to realize the switching of the water guide member 32 between the drain position and the water guide position. The rotating driving member 33 can be a stepping motor which can be controlled to automatically rotate to realize the switching of the positions according to the instruction of the control member of the air conditioner.

[0052] In some embodiments, the outer circumferential wall of the rotating shaft 321 has a sealing member 323, which is clamped between the rotating shaft 321 and the water pan body 31 to divide the water pan body 31 into the water area 311 when the water guide 32 is in the water guide position, so that the condensed water flowing through the water guide is stored in the water area 311. When the water guide 32 is in the water discharge position, the sealing member 323 rotates with the rotating shaft 321 and is separated from the water pan body 31. At this time, it can be understood that the condensed water in the water area 311 will be discharged through the drain hole in time. The sealing member 323 is specifically, for example, a rubber strip.

[0053] In some embodiments, the rotating shaft 321 has a sliding groove extending along its length direction, and the sealing member 323 has a clamping portion which is slidingly connected in the sliding groove. Since the sealing member 323 is a consumable part, the sliding clamping mode can facilitate the replacement and maintenance of the sealing member 323.

[0054] In some embodiments, the water collection member 5 is arranged in the water collection area 312, and the water collection member 5 has a water falling hole 51 corresponding to the drain hole and being blocked by the blocking portion 3221. By arranging the water collection member 5 in the water collection area 312, the condensed water can be prevented from directly contacting the water pan body 31 due to excessively low temperature, so that condensation is prevented from occurring on the outside of the water pan body 31. It can be understood that the water collection member 5 completely covers the water collection area 312 and has a corresponding water collection space formed thereon. Generally, the water collection member 5 is made of foam, which has good heat preservation and insulation effect and low price and small quality. In order to timely discharge the condensed water in the water area 311 when the water guide 32 is in the water discharge position, the water collection member 5 has a flow gap with the water pan body 31, and the flow gap is communicated with the drain hole on the water pan body 31.

[0055] The height of the edge position of the water collection member 5 is higher than the height of the middle position, and the height of the water falling hole 51 is the lowest, so that the condensed water in the water collection member 5 can be smoothly discharged when the water guide 32 is in the water discharge position.

[0056] In a preferred embodiment, the water pan assembly 3 further has a water injection structure 34 which is communicated with the water area 311. Through the water injection structure 34, the user can add water to the water area 311 when the amount of condensed water formed by the air conditioner is insufficient, so as to ensure the normal operation of the air conditioner under the water use condition. For example, when the temperature and humidity of the current environment are low, the amount of condensed water formed by the heat exchanger at low temperature is insufficient for water washing. The air conditioner can detect the real-time water level in the water area 311 through a corresponding liquid level sensor and issue a corresponding prompt to prompt the user to add water to meet the needs of cleaning, humidifying or rapid heating.

[0057] According to the embodiment of the present application, a control method of a cabinet air conditioner is also provided, for controlling the cabinet air conditioner as described above, comprising the following steps:

[0058] Obtaining the operation mode of the air conditioner;

[0059] According to the operation mode, judging whether the operation mode is a water-using condition, the operation mode corresponding to the water-using condition including at least one of a heat exchanger cleaning mode, a fan blade cleaning mode, a drain pipe cleaning mode, a humidifying mode, and a fast heating mode;

[0060] When the operation mode is the water-using condition, controlling the water guide member 32 to be in the water guiding position.

[0061] In the technical solution, when the operation mode is the operation mode corresponding to the water-using condition, the water guide member 32 is controlled to be in the water guiding position, so as to form a water hitting area on the water pan body 31 for sealing and containing the condensed water, and the condensed water formed by the heat exchanger 4 can be quickly concentrated in the water hitting area 311 through the water guide member 32, which is beneficial to the subsequent utilization of the condensed water.

[0062] Referring to Figure 8 When the operation mode is the heat exchanger cleaning mode and the water level of the condensed water in the water hitting area 311 reaches a first set height h1, the lower axial fan blade 2 is controlled to rotate at a low speed in the second rotation direction (for example, a forward direction, the same below) alternately for a first preset time length, so as to realize the omnibearing cleaning of the heat exchanger 4 from the bottom to the top; or, when the operation mode is the fan blade cleaning mode and the water level of the condensed water in the water hitting area 311 reaches a second set height h2, the lower axial fan blade 2 is controlled to rotate at a low speed in the first rotation direction (for example, a reverse direction, the same below) alternately for a second preset time length, so as to realize the cleaning of the lower axial fan blade 2 and the upper axial fan blade 1; or, when the operation mode is the drain pipe cleaning mode and the water level of the condensed water in the water hitting area 311 reaches a third set height h3, the lower axial fan blade 2 is controlled to be static and the water guide member 32 is controlled to be in the discharging position, and this process can be alternately performed for multiple times according to the situation when the amount of condensed water is sufficient, so as to realize the cleaning of the drain pipe by using the impact force of the condensed water. Figure 9As shown, when the operation mode is the humidification mode and the condensate water level in the water hitting area 311 reaches the fourth set height h4, the lower axial flow fan blade 2 is controlled to rotate at a low speed in the second rotation direction alternately for a third preset time length, and then the air conditioner is controlled to operate in the cooling or heating mode. In this way, the condensate water splashed on the heat exchanger 4 can humidify the indoor space during the subsequent operation in the cooling or heating mode, thereby improving the comfort of the user. Alternatively, when the operation mode is the fast heating mode and the condensate water level in the water hitting area 311 reaches the fifth set height h5, the lower axial flow fan blade 2 is controlled to rotate at a low speed in the second rotation direction alternately for a fourth preset time length, and then the air conditioner is controlled to operate in the heating mode. In this way, when the air conditioner operates in the fast heating mode, the heat in the at least room temperature condensate water in the water hitting area 311 can be fully utilized to prevent the blowing of cold air at the initial stage of the fast heating mode, and to prevent the phenomenon of serious frosting caused by the low temperature of the refrigerant entering the outdoor heat exchanger from the indoor heat exchanger, that is, to at least slow down the frosting.

[0063] The degrees h1, h2, h3, h4 and h5 can be the same or different according to actual needs, and the first, second, third, fourth preset time lengths can be the same or different.

[0064] In some embodiments, when the operation mode is the water use condition and the water guide 32 is in the water guiding position, the temperature and humidity of the current environment are obtained; when the obtained temperature and humidity of the current environment are lower than the target temperature and humidity, the user is prompted to add water to the water hitting area 311, so as to prevent the accumulation of insufficient condensate water in the water hitting area 311 due to unsuitable temperature and humidity, and reduce the effect in the cleaning or humidification, fast heating mode; and / or after the operation in each operation mode corresponding to the water use condition ends, the water guide 32 is controlled to be in the water draining position, so as to drain the remaining condensate water or sewage generated by cleaning in the water hitting area 311 in time.

[0065] It is easy for those skilled in the art to understand that the advantageous technical features of each mode described above can be freely combined and superimposed without conflict.

[0066] The above merely describes the preferred embodiments of the present application and should not be used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above merely describes the preferred embodiments of the present application and should not be used to limit the present application.
