Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

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, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in 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.

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.

The outdoor unit of the air conditioner (i.e., the air conditioner indoor unit 1) refers to a portion of the refrigeration cycle that includes a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and the expansion valve may be provided in either the indoor unit or the outdoor unit (i.e., the air conditioner outdoor unit).

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

An air conditioner indoor unit 1 according to an embodiment of the present invention will be described with reference to fig. 1 to 9.

As shown in fig. 1 to 6, an air conditioner indoor unit 1 according to an embodiment of the present invention includes: the casing 10, the shaft sleeve 20 and the air deflector 30. The cabinet 10 is placed on the floor of an indoor space, that is, the indoor unit 1 of the air conditioner is a cabinet.

The assembly mode can effectively limit the rotation of the shaft sleeve 20 relative to the mounting hole 11 of the casing 10, so that only the rotating shaft 31 and the shaft sleeve 20 need to rotate between the three, and the air deflector 30 can be prevented from being fixed due to the fact that the space between the casing 10 and the shaft sleeve 20 is not limited.

Therefore, the shaft sleeve 20 is fixed at the mounting hole 11 through circumferential limiting matching of the second limiting part 21 and the first limiting part 12, so that when the air guide plate 30 is adjusted to adjust the air supply direction, relative rotation cannot occur between the shaft sleeve 20 and the casing 10, and relative rotation cannot occur between the shaft sleeve 20 and the casing 10, so that the mounting reliability between the shaft sleeve 20 and the casing 10 can be ensured, and the phenomenon that the air guide plate 30 cannot be fixed due to deformation of the shaft sleeve 20 and the casing 10 can be avoided.
