The hanging air conditioner further comprises an electric control box 600, wherein the electric control box 600 is arranged in the shell 100; a circuit board is arranged in the electric control box 600 and is electrically connected with the driving motor 500 through a circuit; the electric control board is connected with the indoor heat exchanger 200 through a first circuit, and one end of the first circuit, which is close to the circuit board, is higher than one end of the first circuit, which is close to the indoor heat exchanger 200.

In order to increase the stability of the fresh air fan 300 during operation, the end of the second connecting shaft 301 away from the connecting piece 110 is connected with the first bearing component 120, the first bearing component 120 is mounted on the second half shell 742, and the first bearing component 120 is used for supporting the second connecting shaft 301 to rotate, so that the stability of the fresh air fan 300 during operation is increased, and the noise and vibration of the fresh air fan 300 during operation are reduced. Since the first bearing member 120 is mounted on the second half shell 742, no additional bearing seat is required to mount the first bearing member 120, thereby reducing the number of integral parts and facilitating assembly.

Specifically, as shown in fig. 15-18, the first bearing component 120 is located at the center of the fresh air grille 7421, and by installing the first bearing component 120 at the fresh air grille 7421 of the second half shell 742, a bearing seat for installing the first bearing component 120 can be omitted, so that the fresh air fan 300 can be effectively ensured to operate stably, and meanwhile, the number of structural components is minimized, the efficiency is high, and the cost is low.

It should be noted that, although the first bearing member 120 is mounted at the fresh air grille 7421 and has a certain blocking effect on the outdoor fresh air entering the second fresh air chamber 760 from the first fresh air chamber 750, the blocking effect is weaker, and the blocking effect of the first bearing member 120 on the outdoor fresh air can be compensated by adjusting the opening size of the fresh air grille 7421.

In some embodiments, the first bearing component 120 is disposed through the fresh air grille 7421, and two ends of the first bearing component 120 along the axial direction of the heat exchange fan 400 extend into the second fresh air chamber 760 and the first fresh air chamber 750, respectively, so as to increase the installation firmness of the first bearing component 120. Because the second half shell 742 is provided with the fresh air grid 7421 with limited thickness and strength, the first bearing component 120 passes through the fresh air grid 7421 to be arranged, so that the stress of the first bearing component 120 and the second half shell 742 is balanced, and the connection reliability of the first bearing component 120 and the second half shell 742 is improved.

In some embodiments, second half shell 742 is provided with a bearing mount 7422, and first bearing component 120 is located inside fresh air scroll 700 and mounted to bearing mount 7422.

In other embodiments, the bearing mounting portion 7422 is a mounting through hole provided on the fresh air grille 7421, and the first bearing member 120 is engaged with the mounting through hole, so that the first bearing member 120 is mounted on the second half shell 742.

In other embodiments, the first bearing member 120 is provided with a mounting groove 121, the outer edge of the mounting opening is provided with a positioning table 7423, and the positioning table 7423 is provided in the mounting groove 121, so that the first bearing member 120 is mounted at the mounting opening. The mounting groove 121 extends in the circumferential direction of the first bearing member 120 and is provided in an annular shape.

In other embodiments, the first bearing component 120 includes a bearing sleeve and a bearing bead, the bearing bead is connected with the second connecting shaft 301, the bearing bead is disposed inside the bearing sleeve, and the bearing sleeve is made of soft materials such as rubber or silica gel. The mounting groove 121 is provided in the outer peripheral wall of the bearing housing.

In order to further support the rotation of the second connection shaft 301 and increase the operational stability of the fresh air fan 300, one end of the second connection shaft 301, which is close to the connection member 110 along the length direction of the housing 100, is connected with a second bearing member 130, and the second bearing member 130 is mounted on the fresh air volute 700 and is located at the shaft hole 210, and the second bearing member 130 can also prevent the vibration of the fresh air fan 300 generated along the axial direction during operation.

Specifically, a side of the first half-shell 741 facing the heat exchange fan 400 is provided with a volute connecting portion 7411, and the volute connecting portion 7411 is located at the shaft hole 210; the scroll case connecting part 7411 defines a mounting through chamber which communicates with the shaft hole 210 and communicates with the second fresh air chamber 760, both end openings of the mounting through chamber are correspondingly provided toward the fresh air fan 300 and the heat exchange fan 400, the second bearing member 130 is provided in the mounting through chamber, and the outer circumferential wall of the second bearing member 130 is in contact with the inner wall of the mounting through chamber. The second bearing member 130 is installed by using the volute connecting part 7411, so that an installation seat for installing the second bearing member 130 is omitted, parts of the indoor unit of the air conditioner are reduced, and the assembly is convenient.

Because the second connecting shaft 301 passes through the shaft hole 210, a gap needs to be left between the second connecting shaft 301 and the inner edge of the shaft hole 210 to prevent the second connecting shaft 301 from being unable to rotate due to interference fit between the second connecting shaft 301 and the inner edge of the shaft hole 210, but the gap between the inner edge of the shaft hole and the second connecting shaft 301 can cause leakage of outdoor fresh air in the second fresh air cavity 760 from the connecting gap, so that condensation will be generated around the shaft hole 210 and on the second connecting shaft 301, and product quality is affected. Also, the second connection shaft 301 needs to be provided with a positioning member to position the installation position of the fresh air fan 300. Since the positioning member is generally larger in size than the second coupling shaft 301, there is a large gap between the second motor shaft or coupling shaft and the shaft hole 210. Therefore, the fresh air in the second fresh air chamber 760 is easily leaked from the gap.

By providing the second bearing member 130 in the installation through-cavity, the installation through-cavity can be closed by the second bearing member 130, preventing dew from being generated around the shaft hole 210 and on the second connection shaft 301.

Since the driving motor 500 drives the heat exchange fan 400 and the fresh air fan 300 to operate simultaneously, the fresh air fan 300 cannot stop working alone, so that the fresh air function cannot be turned off when the indoor unit of the air conditioner works, therefore, the indoor unit of the air conditioner opens or closes the fresh air inlet 710 by arranging the switch assembly at the fresh air inlet 710, so as to control whether the outdoor fresh air is introduced into the first fresh air cavity 750, thereby controlling the opening and closing of the fresh air function.

When the indoor unit of the air conditioner works and the fresh air function needs to be closed, the fresh air inlet 710 is closed to prevent outdoor fresh air from being introduced into the first fresh air cavity 750, so that the outdoor fresh air is prevented from flowing indoors from the fresh air outlet 720; when the fresh air function needs to be started, the fresh air inlet 710 is opened, so that the outdoor fresh air is introduced into the first fresh air cavity 750 from the fresh air inlet 710, and the outdoor fresh air flows indoors from the fresh air outlet 720.

It should be noted that, the switch assembly closes the fresh air inlet 710 to prevent the fresh air from flowing backward to the room when the indoor unit of the air conditioner is closed, so that the noise and the wind sense of the indoor air when the fresh air function is not opened are reduced, and the use experience of the user is improved.
