The air conditioner 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.

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

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed 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 cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

During assembly, the wire pressing member 500 is first fixed to the reinforcing compression 112 by a fastener such as a screw, and after the motor 210 is installed, the wire harness led out from the motor 210 is inserted into the lower portion of the blocking portion 530 and into the wire passing gap from the gap between the limiting portion 520 and the bottom plate 120.

The pencil is restricted in crimping piece 500 below, and spacing portion 520 can prevent that the pencil from deviating from the line clearance of crossing, in motor 210 operation in-process, is favorable to avoiding the pencil to be worn and torn by the flabellum that is located motor 210 top, realizes the reasonable line of walking of pencil.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above embodiments of the present invention are only examples, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also intended to be covered by the scope of the present invention.
