DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] In the prior art, most of the wind indoor units are installed in the ceiling during the installation process. Since the indoor fan needs to be inspected and maintained regularly, an inspection port for the indoor fan is reserved on the ceiling 400. However, since the opening is too narrow, the repair and maintenance process will be slow, affecting the efficiency of the wind indoor unit. In the actual use of the wind indoor unit, the indoor and outdoor air will be converted. Most of them will use a filter plate 308 to filter the circulating air to prevent dust from polluting the indoor environment. Although the filter plate 308 can filter impurities in the air, if the filter plate 308 is not regularly maintained, the impurities will clog the filter screen, resulting in low air outlet effect of the wind indoor unit, thereby affecting the heating and cooling efficiency of the wind indoor unit, and some stubborn dust will fall into the fins of the evaporator 106. The evaporator 106 needs to be regularly maintained, which will increase the user's workload and reduce the practicality of the wind indoor unit.

[0022] To this end, the purpose of the present invention is at least to split the indoor unit casing of the wind turbine into a lower device casing 101 and an upper device casing 114, and to split and splice the two as a whole through a lifting and disassembly assembly 300, and at the same time, the linkage installation frame 319 can assist in the disassembly of the filter plate 308, which is not only convenient for the inspection and maintenance of the evaporator 106, but also convenient for daily maintenance of the filter plate 308. During the operation of the indoor fan, the self-cleaning component 200 can perform multi-directional self-cleaning on the surface of the evaporator 106, and can also cooperate with the blower wheel 324 to speed up the wind speed of the air in the wind turbine indoor unit, thereby improving the air exchange efficiency and practicality of the wind turbine indoor unit, reducing the number of inspections, and extending the service life of the wind turbine indoor unit.
