Since the heat exchange fan 400 and the fresh air fan 300 are driven by the driving motor 500 to operate simultaneously, the fresh air fan 300 cannot be independently stopped, so that the fresh air function cannot be independently turned off when the hanging air conditioner works, and therefore, the 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 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, when the switch assembly 770 closes the fresh air inlet 710, the outdoor fresh air can be prevented from flowing backward to the room when the hanging air conditioner stops working, so that the noise and the wind sense of the indoor air when the fresh air function is not started are reduced, and the use experience of users is improved. It should be further noted that, the specific structure of the switch assembly 770 and the principle of closing the fresh air inlet 710 belong to conventional technical means in the art, and will not be described herein.

Although the switch assembly 770 closes the fresh air inlet 710 to prevent outdoor fresh air from being introduced into the room by the fresh air inlet 710, when the hanging type air conditioner works normally but the fresh air inlet 710 is closed, the fresh air fan 300 rotates synchronously with the heat exchange fan 400, the fresh air fan 300 runs, but no extra air enters the fresh air volute 700, so that negative pressure is easily generated in the fresh air volute 700, and blocking noise is easily generated in the fresh air volute 700.

Since the first connecting shaft 110 or the second connecting shaft passes through the shaft hole 210, and the first connecting shaft 110 or the second connecting shaft rotates synchronously with the heat exchange fan 400 and the fresh air fan 300, a gap is usually left between the first connecting shaft 110 and the inner edge of the shaft hole 210 or between the second connecting shaft and the inner edge of the shaft hole 210, so as to ensure that the first connecting shaft 110 can drive the fresh air fan 300 to rotate reliably. Through the operation of the fresh air fan 300, indoor air can enter the fresh air volute 700 through the gap, so that a proper amount of indoor air can enter the fresh air volute 700 through the gap by reasonably determining the size of the gap, so as to compensate air flowing out of the fresh air volute 700 through the fresh air outlet 720, so that the internal pressure of the fresh air volute 700 is kept stable, and the locked-rotor noise generated by the operation of the fresh air fan 300 when the fresh air inlet 710 is closed is reduced.

When the driving motor 500 is a single-shaft motor, the distance from any point on the outer peripheral wall of the first connecting shaft 110 to the axis of the heat exchange fan 400 is D1, the distance from any point in the shaft hole 210 to the axis of the heat exchange fan 400 is D2, and the relationships between D1 and D2 are satisfied:

in some of these embodiments, the axis of the first connecting shaft 110 is disposed collinear with the centerline of the shaft bore 210.

When the driving motor 500 is a dual-shaft motor, the distance from any point on the outer peripheral wall of the second connecting shaft to the axis of the heat exchange fan 400 is D3, the distance from any point along the inner axis of the shaft hole 210 to the axis of the heat exchange fan 400 is D2, and the relationship between D3 and D2 is satisfied:

As shown in fig. 2, the hanging air conditioner further includes an electric control box 600, wherein the electric control box 600 is disposed in the casing 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 support the first connection shaft 110 to rotate, as shown in fig. 6 and 7, the first connection shaft 110 is connected with a bearing part 120, and the bearing part 120 serves to support the first connection shaft 110 to rotate, thereby increasing the smoothness of the heat exchange fan 400 and the fresh air fan 300 when they are operated.

As shown in fig. 7, the housing 100 is further provided with a bearing housing 130 for mounting the bearing member 120, a through cavity extending in the longitudinal direction of the housing 100 is provided in the bearing housing 130, and the bearing member 120 is provided in the through cavity.

In some embodiments, the bearing housing 130 is mounted to the second partition.

In some embodiments, the bearing seat 130 is provided with a clamping portion, the second partition portion is provided with a connecting port, and the clamping portion is arranged in the connecting port, so that the bearing seat 130 is fixedly connected with the second partition portion, and therefore the bearing seat 130 is installed and fixed.

In some embodiments, as shown in fig. 7 and 15, the bearing part 120 includes a bearing housing 121 and bearing beads 122, the bearing beads 122 are mounted in the bearing housing 121, and the first connection shaft 110 is disposed through the bearing beads 122. The bearing housing 121 abuts against the inner wall of the bearing housing 130 so that the bearing member 120 is mounted in the bearing housing 130. The bearing housing 121 is made of soft material such as rubber or silica gel.

The structure of the above-described hanging air conditioner will be described in detail using the driving motor 500 as an example of a single-shaft motor.

The casing 100 is sequentially provided with a second inner cavity 106, a first inner cavity 104 and a third inner cavity 105 along the length direction, the fresh air volute 700 is arranged in the second inner cavity 106, the heat exchange fan 400 is arranged in the first inner cavity 104, and the driving motor 500 is arranged in the third inner cavity 105; the driving motor 500 includes a motor shaft, the motor shaft of the driving motor 500 is connected with the heat exchange fan 400, and the motor shaft of the driving motor 500 is arranged in line with the rotation axis of the heat exchange fan 400; the fresh air volute 700 is provided with the shaft hole 210 towards one side of the heat exchange fan 400, the diameter size of the shaft hole 210 is 20mm, one end of the first connecting shaft 110 penetrates through the shaft hole 210 to be connected with the fresh air fan 300 arranged in the second fresh air cavity 760, the other end of the first connecting shaft 110 is connected with one end of the heat exchange fan 400 far away from the driving motor 500, the axis of the first connecting shaft 110 is arranged in a collinear way with the rotation axis of the heat exchange fan 400, the axis of the first connecting shaft 110 is arranged in a collinear way with the center line of the shaft hole 210, the outer diameter size of the first connecting shaft 110 is 8mm, and a gap of 6mm is reserved between the peripheral wall of the first connecting shaft 110 and the inner edge of the shaft hole 210. The driving motor 500 drives the heat exchange fan 400 to rotate, and the heat exchange fan 400 drives the fresh air fan 300 to rotate through the first connecting shaft 110.

When outdoor fresh air does not need to be introduced, the switch assembly 770 closes the fresh air inlet 710, and indoor air is introduced into the fresh air volute 700 from the gap through the operation of the fresh air fan 300 and flows into the room through the fresh air outlet 720, thereby reducing the locked rotor noise generated when the fresh air fan 300 is operated. When introducing outdoor fresh air, the switch assembly 770 opens the fresh air inlet 710, and the fresh air fan 300 is operated to introduce outdoor fresh air into the fresh air volute 700 from the fresh air inlet 710, although a gap is formed between the first connecting shaft 110 and the inner edge of the shaft hole 210, the outdoor fresh air may leak into the room from the gap, but since the size of the gap is generally smaller than that of the fresh air outlet 720, the leakage amount of the outdoor fresh air is smaller, the condensation amount generated by the leakage of the outdoor fresh air at the first connecting shaft 110 and the shaft hole 210 is also smaller, the influence on the hanging air conditioner is smaller, compared with the influence of the blocking noise generated by the operation of the fresh air fan 300 when the air inlet 710 is closed, the outdoor fresh air leakage and the condensation amount generated by the leakage of the outdoor fresh air at the first connecting shaft 110 and the shaft hole 210 are negligible.

The hanging air conditioner simultaneously drives the fresh air fan 300 and the heat exchange fan 400 to rotate by arranging the driving motor 500, so that one driving motor 500 is saved, and the integral structure of the hanging air conditioner can be simplified; the fresh air inlet 710 is opened or closed by arranging the switch assembly 770 so as to meet the requirements of users for introducing outdoor fresh air and not introducing outdoor fresh air; vibration and noise are inevitably generated when the first connecting shaft 110 rotates, the first connecting shaft 110 can be prevented from being contacted with the fresh air volute 700 by arranging a gap between the shaft hole 210 and the first connecting shaft 110, and the fresh air fan 300 is arranged in the fresh air volute 700, but the fresh air fan 300 is not directly contacted with the fresh air volute 700, so that the vibration and noise generated when the first connecting shaft 110 rotates can be prevented from being transmitted to the fresh air volute 700; through rationally determining the size of the gap between the shaft hole 210 and the first connecting shaft 110, indoor air can enter the fresh air volute 700 from the gap, and the pressure inside the fresh air volute 700 is kept stable, so that the phenomenon that the interior of the fresh air volute 700 generates locked-rotor noise due to synchronous rotation of the fresh air fan 300 and the heat exchange fan 400 when the fresh air inlet 710 is closed is avoided.

The hanging air conditioner is simple and compact in structure, omits a driving motor 500, and generates small locked rotor noise in the fresh air volute 700 when the fresh air function is closed.
