[0087] The indoor unit of the wall-mounted air conditioner is a component of the air conditioner, wherein the air conditioner also includes the outdoor unit of the air conditioner.

[0088] See also Figure 1-Figure 5The air conditioner 1000 may include a wall mounted air conditioner indoor unit 100 and an air conditioner outdoor unit 200. The wall mounted air conditioner indoor unit 100 is installed in an indoor space. The air conditioner outdoor unit 200 is installed in an outdoor space for heat exchange with an outdoor environment.

[0089] The wall-mounted air conditioner indoor unit 100 includes a main body 300, the main body 300 has a bottom and a top, the height direction of the main body 300 is from the bottom of the main body 300 to the top of the main body 300, and the main body 300 also has a length direction, wherein one side of the main body 300 in the left-right direction to the other side thereof is the length direction of the main body 300. The main body 300 has a front side and a rear side that are arranged oppositely, wherein the side of the main body 300 facing the user is the front side of the main body 300, and the front and rear direction of the main body 300 is from the front side of the main body 300 to the rear side of the main body 300.

[0090] The main body 300 may include a housing 3 , which is disposed in an indoor space. The housing 3 has a front side and a rear side that are oppositely disposed, wherein a side of the housing 3 facing a user is the front side of the housing 3 .

[0091] The main body 300 may include a heat exchange air inlet 31, which is disposed at the top of the housing 3. During cooling or heating, indoor air may enter the interior of the housing 3 through the heat exchange air inlet 31.

[0092] The main body 300 may include a first cavity formed inside the housing 3 . The first cavity is communicated with the heat exchange air inlet 31 , and indoor air may enter the first cavity through the heat exchange air inlet 31 .

[0093] The main body 300 may include a heat exchange outlet 32, which is disposed at the bottom of the housing 3, and the first cavity is respectively connected to the heat exchange inlet 31 and the heat exchange outlet 32. When cooling or heating, the indoor air flows into the first cavity through the heat exchange inlet 31 and flows into the room through the heat exchange outlet 32.

[0094] The main body 300 may include an indoor heat exchanger 1001 , which is disposed in the first cavity. The indoor heat exchanger 1001 is used to exchange heat with indoor air entering the first cavity.

[0095] In some embodiments, the main body 300 may include a base 4 , which is disposed in the first cavity and has a heat exchange air duct 41 formed in the base 4 .

[0096] In some embodiments, the main body 300 may include a heat exchange fan 5, which is disposed in the heat exchange air duct 41, and the axial direction of the heat exchange fan 5 is in the same direction as the length direction of the main body 300. Through the operation of the heat exchange fan 5, indoor air is introduced into the first cavity from the heat exchange air inlet, then flows through the indoor heat exchanger 1001, flows through the heat exchange air duct 41, and then flows into the room through the heat exchange air outlet 32.

[0097] It can be arranged that the heat exchange fan 5 is arranged on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to the air flow and increase the air intake into the room.

[0098] In some embodiments, the air conditioner outdoor unit 200 is disposed in an outdoor space, and the air conditioner outdoor unit 200 includes a housing, a second cavity is disposed in the housing, and an outdoor air inlet and an outdoor air outlet are disposed on the housing. The outdoor air inlet is connected to the outdoor space and the second cavity, and the outdoor air outlet is connected to the outdoor space and the second cavity.

[0099] In some embodiments, an outdoor heat exchanger 202 is disposed in the shell, and refrigerant flows in the outdoor heat exchanger 202 .

[0101] In some embodiments, the air-conditioning outdoor unit 200 may include a throttling device 204, which is disposed in the second cavity and is used to expand the liquid refrigerant in a high-temperature and high-pressure state into a low-pressure liquid refrigerant. The throttling device 204 may be disposed on the leeward side of the outdoor heat exchanger 202, and may be conveniently connected to the compressor 201.

[0102] The air conditioner 1000 performs a refrigeration cycle of the air conditioner 1000 by using the compressor 201, the outdoor heat exchanger 202, the throttling device 204 and the indoor heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0103] The compressor 201 compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202 .

[0104] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0105] The throttling device 204 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0106] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201 .

[0107] The indoor heat exchanger 1001 can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0108] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one is a condenser and the other is an evaporator. When the indoor heat exchanger 1001 is used as a condenser and the outdoor heat exchanger 202 is used as an evaporator, the air conditioner 1000 is used as a heater in the heating mode. When the indoor heat exchanger 1001 is used as an evaporator and the outdoor heat exchanger 202 is used as a condenser, the air conditioner 1000 is used as a cooler in the cooling mode.

After the anti-collision rib contacts the first bearing 7, the first bearing 7 acts as a buffer for the anti-collision rib and the heat exchange fan 5, thereby preventing damage to the heat exchange fan 5 or the drive motor due to impact.

[0143] In some embodiments, the fan shaft 56 is disposed through the first bearing 7, and the fan shaft 56 can rotate relative to the first bearing 7. The first bearing 7 can limit the fan shaft 56 to rotate around the same rotation axis.

[0144] In some embodiments, the wall-mounted air conditioner indoor unit may further include a second bearing, which is connected to the second axial end 58 of the heat exchange fan 5. In the axial direction of the heat exchange fan 5, the second bearing is arranged opposite to the first bearing 7, and the fan shaft 56 passes through the second bearing. The first bearing 7 and the second bearing can define the rotation center of the heat exchange fan 5 to prevent the heat exchange fan 5 from shaking in the radial direction when rotating.

[0145] In some embodiments, the inner stator component 63 may include a bracket, which may be configured as an iron core, and the bracket is disposed inside the enclosed annular portion of the outer rotor component 62 .

[0146] In some embodiments, the inner stator member 63 may include a coil, which may be a copper coil or an aluminum coil. The coil is wound around a bracket, and the coil is energized to make the bracket magnetic. When the drive motor 6 is energized, current flows through the coil wound around the bracket to generate an induced magnetic field, making the bracket magnetic. The induced magnetic field interacts with the magnetic field generated by the outer rotor member 62, which is set as a permanent magnet, so that the outer rotor member 62 rotates relative to the inner stator member 63, and the rotation of the outer rotor member 62 drives the heat exchange fan 5 to rotate synchronously.

[0147] In some embodiments, the inner stator 63 may include a covering portion, which wraps around the periphery of the bracket and the coil, and the covering portion is integrally formed with the bracket and the coil. When installing the inner stator 63, the bracket, the coil and the covering portion are assembled as a whole.
