In other embodiments, the bearing housing 121 is further provided with a reinforcing portion 123, a communication cavity for the connecting shaft 110 to pass through is provided inside the reinforcing portion 123, and the reinforcing portion 123 is used for increasing the contact area between the bearing housing 121 and the connecting shaft 110, so as to increase the supporting effect of the bearing component 120 on the connecting shaft 110.

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 above-mentioned hanging air conditioner uses the switch assembly 770 to open or close the fresh air inlet 710 by arranging the switch assembly 770 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 hanging air conditioner works, when the fresh air function needs to be closed, the fresh air inlet 710 is closed, so that the outdoor fresh air can be prevented from being introduced into the first fresh air cavity 750, and 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, when the switch assembly 770 closes the fresh air inlet 710, the fresh air can be prevented 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.

Since the fresh air fan 300 and the heat exchanging fan 400 are driven to operate by the same driving motor 500, the operation speed of the fresh air fan 300 is the same as that of the heat exchanging fan 400, and the fresh air fan 300 and the heat exchanging fan 400 are disposed with the same rotation axis. In the conventional hanging type air conditioner, since the fresh air fan 300 and the heat exchanging fan 400 are respectively connected to the motor, the fresh air fan 300 and the heat exchanging fan 400 are operated independently, and the operation speed of the fresh air fan 300 is faster than that of the heat exchanging fan 400, when the operation speed of the fresh air fan 300 is the same as that of the heat exchanging fan 400, the fresh air introducing capability of the fresh air fan 300 is lowered.

When the outdoor fresh air enters the first fresh air cavity 750 from the fresh air inlet 710, the contact of the inner wall of the first fresh air cavity 750 of the outdoor fresh air can generate larger fluid resistance, so that the outdoor fresh air is prevented from entering the first fresh air cavity 750; in this embodiment, the air inlet direction of the outdoor fresh air into the first fresh air chamber 750 is used to reduce the fluid resistance generated when the outdoor fresh air enters the first fresh air chamber 750, so as to increase the fresh air volume entering the first fresh air chamber 750.

Specifically, as shown in fig. 12, the opening direction of the fresh air inlet 710 is set towards the bottom of the casing 100, and a first included angle α is formed between the center line 230 of the fresh air inlet 710 and the height direction of the casing 100, so that the center line 230 of the fresh air inlet 710 is obliquely set along the height direction of the casing 100, thereby reducing the fluid resistance of the outdoor fresh air after entering the first fresh air cavity 750, so that the outdoor fresh air can be quickly sucked into the fresh air fan 300, and further increasing the air guiding efficiency of the fresh air fan 300.

In some embodiments, the first included angle α satisfies the relationship: alpha is more than 0 DEG and less than or equal to 30 deg. When the first included angle alpha is 0 degrees, the outdoor fresh air enters the first fresh air cavity 750 from the fresh air inlet 710, and the generated fluid resistance is larger; when the first included angle α is 30 °, the outdoor fresh air enters the first fresh air chamber 750 from the fresh air inlet 710, so that the generated fluid resistance is smaller, and the fresh air volume entering the first fresh air chamber 750 increases.

In some embodiments, the fresh air volute 700 is connected with a fresh air duct 900, the fresh air duct 900 is disposed at the fresh air inlet 710, and the fresh air duct 900 communicates with the outside to introduce outdoor fresh air into the first fresh air chamber 750.

As shown in fig. 13, a plane perpendicular to the center line 230 of the fresh air intake 710 is defined as a first plane 240, and a second included angle β is defined between the first plane 240 and the horizontal plane 250, where the second included angle β satisfies the relationship: beta is more than 0 DEG and less than or equal to 30 deg. The second included angle β is the same as the first included angle α in terms of degree.

Further, as shown in fig. 10, a reserved space 260 is defined between the lower portion of the fresh air volute 700 and the inner wall of the bottom of the housing 100, and the fresh air pipe 900, the on-line pipe 270, the drain pipe 280 and other pipes are generally routed through the reserved space 260, so that the fresh air pipe 900, the on-line pipe 270, the drain pipe 280 and other pipes can pass through the housing 100. In the conventional hanging type air conditioner, the rotation axis of the fresh air fan 300 is generally higher than that of the heat exchange fan 400, and when the fresh air fan 300 and the heat exchange fan 400 are arranged along the rotation axis, the position of the fresh air fan 300 moves downwards, so that the fresh air volute 700 also moves downwards, the reserved space 260 below the fresh air volute 700 becomes smaller, and the pipe running space of the pipelines such as the fresh air pipe 900, the online pipe 270, the drain pipe 280 and the like is narrow, which is not beneficial to the pipe running arrangement of the pipelines such as the fresh air pipe 900, the online pipe 270, the drain pipe 280 and the like.

Because the reserved space 260 is defined by the outer wall of the fresh air inlet 710 formed by the fresh air volute 700 and the inner wall of the bottom of the housing 100, and the reserved space 260 is disposed near the rear side of the housing 100, in this embodiment, the outer wall of the fresh air volute 700 formed by the fresh air inlet 710 is obliquely disposed along the thickness direction of the housing 100 from the front side of the housing 100 to the rear side of the housing 100 toward the direction near the top of the housing 100, so as to increase the volume of the reserved space 260, and thus the pipes such as the fresh air pipe 900, the drain pipe 280, the coupling pipe 270 and the like inside the housing 100 can pass through the reserved space 260 and penetrate out of the housing 100.

Through enabling the outer wall of the fresh air volute 700 provided with the fresh air inlet 710 to be obliquely arranged along the thickness direction of the shell 100 from the front side of the shell 100 to the rear side of the shell 100 towards the direction close to the top of the shell 100, the distance between the outer wall of the fresh air volute 700 towards the bottom of the shell 100 and the inner wall of the bottom of the shell 100 can be gradually increased along the thickness direction of the shell 100 from the front side of the shell 100 to the rear side of the shell 100, so that the volume of the reserved space 260 is increased, and pipelines such as a fresh air pipe 900, a drain pipe 280, a coupling pipe 270 and the like are conveniently arranged.

It should be noted that, the outer wall of the fresh air inlet 710 of the fresh air volute 700 is obliquely arranged from the front side of the housing 100 to the rear side of the housing 100 along the thickness direction of the housing 100 toward the direction close to the top of the housing 100, which can be achieved by adjusting the angle of the fresh air volute 700 mounted to the housing 100 on one hand, and the outer wall of the fresh air volute 700 of the fresh air inlet 710 can be designed to be an oblique structure without changing the angle of the fresh air volute 700 mounted to the housing 100 on the other hand.

It should be further noted that, the center line 230 of the fresh air inlet 710 may be disposed perpendicular to a plane where the outer wall of the fresh air volute 700 is disposed at the fresh air inlet 710, or may be disposed at an angle to a plane where the outer wall of the fresh air volute 700 is disposed at the fresh air inlet 710.

In some embodiments, the fresh air scroll 700 needs to be installed by rotating at a certain angle, and the center line 230 of the fresh air inlet 710 is perpendicular to the outer wall of the fresh air scroll 700 that is provided with the fresh air inlet 710. At this time, after the fresh air volute 700 is rotated in the vertical direction until the outer wall of the fresh air volute 700, which is provided with the fresh air inlet 710, is obliquely arranged in the direction from the front side of the housing 100 to the rear side of the housing 100 towards the direction close to the top of the housing 100 along the thickness direction of the housing 100, correspondingly, the opening direction of the fresh air inlet 710 is also inclined, and the center line 230 of the fresh air inlet 710 and the height direction of the housing 100 form a first included angle α.

It is believed that the first included angle α is created by rotating the fresh air volute 700 in a vertical plane. When the fresh air volute 700 rotates in the vertical plane inside the housing 100, one of the corners at the top of the fresh air volute 700 may interfere with the inner wall of the housing 100, so that the fresh air volute 700 cannot rotate, and when one of the corners at the top of the fresh air volute 700 interferes with the inner wall of the housing 100, the first included angle α is the maximum value of the value range.

Specifically, when the first included angle α is 0 °, the opening direction of the fresh air inlet 710 is vertically downward, and the outer wall of the fresh air inlet 710 is set along the horizontal direction by the fresh air volute 700, meanwhile, the center line 230 of the fresh air inlet 710 is vertically set with the outer wall of the fresh air inlet 710 by the fresh air volute 700, at this time, when the outdoor fresh air enters the first fresh air cavity 750 from the fresh air inlet 710, the inner wall of the first fresh air cavity 750 of the outdoor fresh air contacts to generate a larger fluid resistance, so as to prevent the outdoor fresh air from entering the first fresh air cavity 750.

When one of the corners at the top of the fresh air volute 700 interferes with the inner wall of the casing 100, the first included angle α is the maximum value of the range of values. It should be noted that, at this time, the degree of the first included angle α may be 30 °, or may be greater than 30 °, or may be less than 30 °, and the first included angle α satisfies the relation: when alpha is more than 0 degrees and less than or equal to 30 degrees, the fluid resistance generated when the outdoor fresh air enters the first fresh air cavity 750 from the fresh air inlet 710 is smaller, and when the degree of the first included angle alpha is 30 degrees, the interference between one corner of the top of the fresh air volute 700 and the inner wall of the shell 100 is not meant.

In other embodiments, the installation angle of the fresh air volute 700 is not required to be changed, and the center line 230 of the fresh air inlet 710 is disposed at an angle with respect to the outer wall of the fresh air volute 700 with respect to the fresh air inlet 710, at this time, if the outer wall of the fresh air volute 700 with respect to the fresh air inlet 710 is disposed along the horizontal direction, the center line 230 of the fresh air inlet 710 will also form a first angle a with respect to the height direction of the housing 100,

At this time, although the air intake efficiency of the fresh air fan 300 can be increased, the space 260 is reduced, and it is inconvenient for the fresh air duct 900, the on-line duct 270, the drain duct 280, and other pipes to pass through, so that the outer wall of the fresh air volute 700 with the fresh air intake 710 needs to be inclined from the front side of the casing 100 to the rear side of the casing 100 in the thickness direction of the casing 100 in a direction approaching the top of the casing 100.

It should be noted that, the value range of the first included angle α varies along with the inclination angle of the outer wall of the fresh air volute 700, which is provided with the fresh air inlet 710, from the front side of the housing 100 to the rear side of the housing 100 along the thickness direction of the housing 100 toward the direction close to the top of the housing 100.

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.

The above-mentioned hanging air conditioner is formed with a first included angle α between the center line 230 of the fresh air inlet 710 and the height direction of the housing 100, where the first included angle α satisfies the following relation: alpha is more than 0 and less than or equal to 30 degrees, so that the central line 230 of the fresh air inlet 710 is obliquely arranged along the height direction of the shell 100, thereby reducing the fluid resistance of the outdoor fresh air after entering the first fresh air cavity 750, enabling the outdoor fresh air to be quickly sucked into the fresh air fan 300, and further increasing the air inducing efficiency of the fresh air fan 300; the outer wall of the fresh air volute 700 provided with the fresh air inlet 710 is obliquely arranged from the front side of the casing 100 to the rear side of the casing 100 along the thickness direction of the casing 100 towards the direction close to the top of the casing 100, so that the distance between the outer wall of the fresh air volute 700 towards the bottom of the casing 100 and the inner wall of the bottom of the casing 100 is gradually increased from the front side of the casing 100 to the rear side of the casing 100 along the thickness direction of the casing 100, the volume of the reserved space 260 is increased, and the arrangement of pipelines such as the fresh air pipe 900, the drain pipe 280, the coupling pipe 270 and the like is facilitated.
