In the present application, a hanging type air conditioner performs a refrigerating cycle of an indoor unit of the air conditioner by using a compressor, a condenser, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges refrigerant gas in a high-temperature and high-pressure state. 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 indoor heat exchanger 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 indoor heat exchanger may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioning indoor unit can adjust the temperature of the indoor space throughout the cycle. The outdoor unit of the air conditioner indoor unit refers to a portion of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner indoor unit includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an indoor heat exchanger. When the indoor heat exchanger is used as a condenser, the air-conditioning indoor unit is used as a heater for a heating mode, and when the indoor heat exchanger is used as an indoor heat exchanger, the air-conditioning indoor unit is used as a cooler for a cooling mode.

the driving motor 400 drives the heat exchange fan 200 and the fresh air fan 300 to synchronously rotate through the connecting shaft 600;

The limiting piece 500 is arranged on the connecting shaft 600; the fresh air volute comprises a first split shell 700 and a second split shell 800, wherein a first installation part is arranged on the first split shell 700, and a second installation part is arranged on the second split shell 800; the first split shell 700 is used for being connected with the second split shell 800, and after the first split shell 700 is connected with the second split shell 800, the first installation part and the second installation part are spliced to form an installation hole; the aperture of the mounting hole is not smaller than the diameter of the connection shaft 600 and smaller than the outer diameter of the stopper 500.

Through the above scheme, when in installation, the first split shell 700 and the second split shell 800 are directly sleeved with the connecting shaft 600, so that the limiting piece 500 is directly positioned between the first split shell 700 and the second split shell 800, and the installation hole is directly sleeved with the connecting shaft 600; the stopper 500 does not need to pass through the mounting hole, so that the aperture of the mounting hole can be reduced, and the possibility of leakage of air flow through the mounting hole can be reduced, so as to improve the sealing property.

In some embodiments, the fresh air volute also includes a second half-shell 900, the second half-shell 900 being disposed on a side of the first split-shell 700 and the second split-shell 800 remote from the heat exchange fan 200; a first receiving chamber is formed between the second half-case 900, the first split-case 700 and the second split-case 800, and the fresh air fan 300 is disposed in the first receiving chamber.

In some embodiments, the second half shell 900 is integrally formed with the second split shell 800. The second half shell 900 is integrally formed with the second split shell 800, so that only the first split shell 700 is installed to close the first accommodating cavity, thereby facilitating manual operation.

In some embodiments, the first split housing 700 is integrally formed with the second half housing 900.

In some embodiments, the first mounting portion is a first mounting groove formed in the first split case 700. The second mounting portion is a second mounting groove formed in the second split case 800. The first mounting groove and the second mounting groove are spliced to form a mounting hole.

In some embodiments, the fresh air volute includes first, second and third half-shells 110, 900, 800 that are joined to one another, with the first and second split shells 700, 800 joined to one another to form the first half-shell. The fresh air volute is composed of the first half shell, the second half shell 900 and the third half shell 110, and is convenient to manufacture and install the fresh air fan 300.

In some embodiments, the limiting member 500 is annular and sleeved on the connecting shaft 600, and the outer diameter of the limiting member 500 is smaller than the aperture of the mounting hole.

In the prior art, the first half shell of the fresh air volute is an integral body, and the mounting hole directly penetrates through the first half shell. And the stopper 500 is provided on the connection shaft 600, and the stopper 500 needs to be mounted to the connection shaft 600 by a special device because of a process problem. If the connection shaft 600 is first passed through the mounting hole, the apparatus for mounting the stopper 500 may interfere with the first half-shell, resulting in that the stopper 500 cannot be mounted. The stopper 500 must be installed on the connection shaft 600 before the connection shaft 600 passes through the installation hole of the first half-shell, and thus the aperture of the installation hole must be greater than the diameter of the stopper 500. Therefore, a larger gap is generated between the mounting hole and the connecting shaft 600, resulting in air leakage, and the sealing performance of the fresh air volute is poor.

In the present application, the first split case 700 and the second split case 800 may directly align the first installation portion and the second installation portion with the connection shaft 600, and splice the first split case 700 and the second split case 800 to form a first half case, so that the installation hole is directly sleeved on the connection shaft 600. The limiting piece 500 does not need to pass through the mounting hole, so that the aperture of the mounting hole can be smaller than the outer diameter of the limiting piece 500, thereby reducing the gap between the mounting hole and the connecting shaft 600 and improving the tightness of the fresh air volute.
