It should be noted that, the first volute casing 31 is provided with a preformed hole 311, the opening direction of the preformed hole 311 extends along the length direction of the casing 1, and the connecting shaft 61 or the second motor shaft may extend into the fresh air cavity 321 through the preformed hole 311 to be connected with the fresh air fan 9.

In practice, the second motor shaft or the connecting shaft 61 of the driving motor 5 needs to be provided with a positioning member to position the installation position of the fresh air fan 9.

The positioning member is generally provided protruding from the outer periphery of the connection shaft 61 or the second motor shaft, and is located in the fresh air chamber 321 to position the connection position of the fresh air fan 9 and the connection shaft 61 or the connection position of the fresh air fan 9 and the second motor shaft. It should be noted that, the minimum value of the range of values from any point on the outer edge of the positioning component to the axis of the connecting shaft 61 is the distance from any point on the outer peripheral wall of the connecting shaft 61 to the axis of the connecting shaft 61, or the minimum value of the range of values from any point on the outer edge of the positioning component to the axis of the second motor shaft is the distance from any point on the outer peripheral wall of the second motor shaft to the axis of the second motor shaft, i.e. the outer diameter size of the positioning component is larger than the outer diameter size of the connecting shaft 61 or the position where the positioning component is arranged on the second motor shaft, so that the positioning component can effectively position the fresh air fan 9.

In some embodiments, the positioning member is removably coupled to the connecting shaft 61 or the second motor shaft; the positioning component is usually a snap ring, and the connecting shaft 61 or the second motor shaft is provided with a positioning groove corresponding to the snap ring, wherein the positioning groove is arranged along the circumferential direction of the connecting shaft 61 or the second motor shaft, and the snap ring is arranged in the positioning groove so that the snap ring is connected with the connecting shaft 61 or the second motor shaft.

In some embodiments, the positioning component and the connecting shaft 61 or the second motor shaft are integrally formed, and the positioning component and the connecting shaft 61 or the positioning component and the second motor shaft are usually formed by turning metal, which belongs to the prior art and is not described herein.

It should be noted that, whether the positioning member is detachably connected to the connecting shaft 61 or the second motor shaft or integrally formed, the positioning member is usually integrated with the connecting shaft 61 or the second motor shaft and then passes through the preformed hole 311 and extends into the fresh air cavity 321 to be connected to the fresh air fan 9, which requires that the inner diameter dimension of the preformed hole 311 is generally larger than the outer diameter dimension of the positioning member, so that the positioning member can freely pass through the preformed hole 311 to be disposed in the fresh air cavity 321, and since the outer diameter dimension of the connecting shaft 61 or the second motor shaft is generally smaller than the outer diameter dimension of the positioning member, a certain gap is formed between the connecting shaft 61 and the preformed hole 311 or between the second motor shaft and the preformed hole 311 when the connecting shaft 61 or the second motor shaft passes through the preformed hole 311.

And when the fresh air fan 9 and the heat exchange fan 6 are operated, the second motor shaft or the connecting shaft 61 also synchronously rotates, and when the second motor shaft or the connecting shaft 61 passes through the preformed hole 311, a gap needs to be reserved between the second motor shaft and the inner edge of the preformed hole 311 or between the connecting shaft 61 and the inner edge of the preformed hole 311 so as to ensure that the second motor shaft or the connecting shaft 61 rotates.

The outdoor fresh air in the fresh air cavity 321 is easy to leak from the gap between the connecting shaft 61 and the preformed hole 311 or the gap between the second motor shaft and the preformed hole 311, so that condensation is generated around the preformed hole 311 and on the connecting shaft 61 or the second motor shaft, and the product quality is affected.

Because the connecting shaft 61 or the second motor shaft needs to rotate when the indoor unit works, a sealing member through hole for the connecting shaft 61 or the second motor shaft to pass through is formed in the sealing member 10, and in order to ensure the reliability that the connecting shaft 61 or the second motor shaft can move relative to the sealing member 10, a certain gap is also required between the connecting shaft 61 or the second motor shaft and the inner edge of the sealing member through hole when the connecting shaft 61 or the second motor shaft passes through the sealing member 10. Although the gap between the connecting shaft 61 and the inner edge of the seal member through hole is smaller than the gap between the connecting shaft 61 and the inner edge of the preformed hole 311, the gap between the second motor shaft and the inner edge of the seal member through hole is smaller than the gap between the second motor shaft and the inner edge of the preformed hole 311, the outdoor fresh air in the fresh air cavity 321 may still leak from the gap between the connecting shaft 61 and the inner edge of the seal member through hole or the gap between the second motor shaft and the inner edge of the preformed hole 311.

Since the connecting shaft 61 or the second motor shaft is generally connected with the bearing member 7 to support the connecting shaft 61 or the second motor shaft to rotate, a transition chamber 103 is provided between the sealing member 10 and the bearing member 7 to introduce the outdoor fresh air leaked from a gap between the connecting shaft 61 and the inner edge of the through hole of the sealing member or a gap between the second motor shaft and the inner edge of the preformed hole 311 into the inside of the bearing member 7, and the leakage of the outdoor fresh air is prevented by the bearing member 7.
