The outermost movable impeller 422b is connected to the inner movable impeller 422a so as to be slidable along the extension shaft 412, and is stopped by a stopper 4221 provided at one end of the inner movable impeller 422a away from the first drive motor 41. The diameter of the impeller positioned on the outer side in the two adjacent impellers is larger than that of the impeller positioned on the inner side, so that the impeller positioned on the outer side can be sleeved on the impeller positioned on the inner side when the impeller positioned on the outer side slides relative to the impeller positioned on the inner side. The extension shaft 412 passes through the fixed impeller 421 and the two movable impellers (422 a and 422 b), and can limit and guide when the movable impellers (422 a and 422 b) slide.

The setting mode has the advantages that: by arranging the impeller group 42 of the blower 4 to be capable of extending and retracting along the axial direction of the first driving motor 41, the suspension angle air conditioner indoor unit can also realize control over the longitudinal air outlet height, and further enriches the air outlet selection of a user, so that the effects of no blowing head at the upper part and no blowing leg at the lower part are achieved, and the user experience is further improved.

With further reference to fig. 11 to 13, the telescopic driving mechanism 423 includes a second driving motor 4231, a drum 4232, and a wire rope 4233, one end of the fixed impeller 421 near the biaxial motor is provided with a conductive slip ring 4211, the conductive slip ring 4211 includes a rotor and a stator electrically connected to each other, the second driving motor 4231 is fixed inside the rotor of the conductive slip ring 4211 and electrically connected to the rotor, the drum 4232 is connected to an output shaft 411 of the second driving motor 4231, and the wire rope 4233 is wound around the drum 4232, one end of which is fixedly connected to the drum 4232, and the other end of which is fixedly connected to the movable impeller 422b located at the outermost side. Elastic members 424, such as springs or elastic rubber, are further provided between the fixed impeller 421 and the movable impeller 422a located inside, and between the movable impellers 422a and 422b, and the elastic members 424 are provided to be elastically deformed to store elastic potential energy when the movable impeller 422a contracts with respect to the fixed impeller 421 or when the movable impeller 422b contracts with respect to the movable impeller 422 a. The expanded state and the contracted state of the crossflow blower are shown in FIGS. 11 and 12. As shown in fig. 13, when the cross flow fan needs to be contracted, the second driving motor 4231 drives the winding drum 4232 to retract the wire rope 4233, the outer movable impeller 422b is driven by the wire rope 4233 and contracted by the compression spring guided by the extension shaft 412, after the outer movable impeller 422b is contracted to a certain stroke, the inner movable impeller 422a is driven by the movable impeller 422b to be contracted, and finally the outer movable impeller 422a and the outer movable impeller are contracted and sleeved on the outer side of the fixed impeller 421. When the second drive motor 4231 drives the drum 4232 to release the wire rope 4233, the outer movable impeller 422b and the inner movable impeller 422a are extended by the elastic force of the spring and the guide of the extension shaft 412, and reach the fully extended position under the restriction of the limit edge 4212 provided on the fixed impeller 421 and the limit edge 4221 provided on the movable impeller 422a located inside.

The above arrangement describes an example of the telescopic driving mechanism 423, and of course, the telescopic driving mechanism 423 may be implemented in various ways, for example, if there is a fear that the conductive slip ring is worn quickly and the maintenance cost is high, a storage battery may be arranged at the motor to supply power to the motor, the indoor unit may be designed to be connected with the storage battery periodically to replenish the electric quantity of the storage battery, and the telescopic driving mechanism may be implemented in various ways, which cannot be listed one by one, but only needs to enable the second driving motor 4231 to operate normally and does not hinder the rotation of the impeller assembly 42.

Particularly, after the air supplement amount is increased, the air amount flowing through the heat exchanger 3 in unit time is increased, the heat exchange efficiency of the air conditioner is also improved, and the heating/cooling performance of the air conditioner is further improved.

As described above, the air supply unit 5 increases the air supply amount, and the sum of the noise generated by the normal operation of the air supply fan 52 and the blower 4 is much lower than the noise generated by the high-speed operation of the blower 4 alone, thereby reducing the noise when the air conditioner outputs a large air amount. And a fresh air pipe 56 and a purification module 55 are added, so that the indoor unit of the suspension angle air conditioner has both fresh air function and purification function. The air duct 54 is added to change the wind direction of the air supply fan 52, so that the air supply effect is better. The humidifying water tank 2 is added, the design of the internal structure of the shell 1 is reduced, the middle block is not needed any more, and the manufacturing is easier. Humidification water tank 2 has still expanded the humidification function of overhang angle air conditioner, and in addition, humidification water tank 2 set up the position and still make forced draught blower 4 when the operation carry out the air current flow through humidification water tank 2 after the heat exchange with heat exchanger 3, humidification water tank 2 adjusts the temperature to the air current to can reach the soft purpose of air-out, prevent that the air-out is too cold or overheated and influence user experience. By setting the impeller set 42 of the cross-flow fan to be capable of extending and retracting along the axial direction of the first driving motor 41, the indoor unit of the suspension-angle air conditioner can also realize control on the longitudinal air outlet height, and can be adjusted according to the actual installation position of the air conditioner and the height parameters of a user, so that the effects of no blowing head from the top and no blowing legs from the bottom are achieved, and the user experience is further improved.
