Detailed Embodiments

[0089] Next, some embodiments of the present disclosure will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0090] This embodiment provides an air conditioner indoor unit, which will be described below with reference to Figures 1 - 20 to describe the air conditioner indoor unit.

[0094] The main body may include a housing 11, and the housing 11 is arranged in the indoor space. The housing 11 has a front side and a rear side that are oppositely arranged. Among them, the side of the housing 11 facing the user is the front side of the housing 11.

[0095] The main body may include a heat exchange air inlet 111, and the heat exchange air inlet 111 is arranged at the top of the housing 11. When refrigerating or heating, indoor air can enter the interior of the housing 11 through the heat exchange air inlet 111.

[0096] The main body may include a first chamber, and the first chamber is arranged inside the housing 11. The first chamber is communicated with the heat exchange air inlet 111, and indoor air can enter the first chamber through the heat exchange air inlet 111.

[0097] The main body may include a heat exchange air outlet 112, and the heat exchange air outlet 112 is arranged at the bottom of the housing 11. The first chamber is respectively communicated with the heat exchange air inlet 111 and the heat exchange air outlet 112. When refrigerating or heating, indoor air flows into the first chamber through the heat exchange air inlet 111 and flows into the room through the heat exchange air outlet 112.

[0098] The main body may include an indoor heat exchanger 1001, and the indoor heat exchanger 1001 is arranged in the first chamber. The indoor heat exchanger 1001 is used for heat exchange with the indoor air entering the first chamber.

[0099] In some embodiments, the main body may include a heat exchange fan, and the heat exchange fan is arranged in the first chamber. The fan can be used to drive indoor air to enter the first chamber through the heat exchange air inlet 111, then flow through the indoor heat exchanger 1001, and flow into the room through the heat exchange air outlet 112. It can be set that the fan is arranged on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to air flow and increase the air intake volume into the room.

[0100] The fan may include a motor and a fan. The drive shaft of the motor is connected to the fan, and the fan is driven by the motor to rotate to drive the air flow in the first chamber.

[0101] In some embodiments, the air conditioner outdoor unit 200 is arranged in the outdoor space. The air conditioner outdoor unit 200 includes a second chamber arranged inside the housing, and an outdoor air inlet and an outdoor air outlet are arranged on the housing. The outdoor air inlet is communicated with the outdoor space and the second chamber, and the outdoor air outlet is communicated with the outdoor space and the second chamber.

[0102] In some embodiments, an outdoor heat exchanger 202 is disposed inside the housing. Refrigerant flows through the outdoor heat exchanger 202, and the refrigerant in the outdoor heat exchanger 202 can be used to exchange heat with the air entering the second chamber and flowing through the outdoor heat exchanger 202.

[0103] In some embodiments, a compressor 201 is disposed inside the housing. The compressor 201 is arranged in the second chamber and is installed at the bottom of the air conditioner outdoor unit 200.

[0104] In some embodiments, the air conditioner outdoor unit 200 may include a throttling device 204. The throttling device 204 is disposed in the second chamber and is used to expand the high-temperature and high-pressure liquid-phase refrigerant into a low-pressure liquid-phase refrigerant. The throttling device 204 can be disposed on the leeward side of the outdoor heat exchanger 202, which is convenient for connection to the compressor 201.

[0105] The air conditioner 1000 performs the 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.

[0106] The compressor 201 compresses the refrigerant gas in the low-temperature and low-pressure state and discharges the refrigerant gas in the high-temperature and high-pressure state. The discharged refrigerant gas flows into the outdoor heat exchanger 202.

[0107] 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.

[0108] 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.

[0109] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in the low-temperature and low-pressure state to the compressor 201.

[0110] The indoor heat exchanger 1001 can achieve a refrigeration effect by exchanging heat with the material to be cooled by using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0111] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one of them 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 serves 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 serves as a cooler in the cooling mode.

[0112] Reference Figures 4 - 15 In some embodiments, the main body may further include a cleaning module, which is arranged corresponding to the heat exchange air inlet, and the cleaning module is used to clean the dust on the filter screen 321.
