[0064] The air conditioner in the present application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0065] The low-temperature and low-pressure refrigerant enters the compressor, which compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0066] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant formed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with the material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0067] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the indoor machine includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0068] The indoor heat exchanger and the outdoor heat exchanger are used as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the indoor machine is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the indoor machine is used as a cooler in a cooling mode.

[0114] Specifically, by arranging the above indoor unit, the air in the room can be exchanged by rotating the fan 4, which is conducive to eliminating the odor in the room; the motor 5 and the volute assembly 3 are detachably arranged on the mounting portion 2, so that the motor 5 and the volute assembly 3 are fixed on one structure, the structure is compact, the space occupancy rate can be reduced, the modular pre-installation is realized, the structure of the indoor unit is more compact, and the production efficiency and market competitiveness can be improved.

[0115] In the description of the above-mentioned embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0116] The above merely describes the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
