Although the rapid cooling/heating function of the above-described air conditioner solves the rapid cooling/heating requirement of the user to some extent, such an air conditioner inevitably has the following problems: the performance (namely the refrigerating/heating effect) and the wind noise of the traditional air conditioner are a pair of irreconcilable contradictions, and the air conditioner increases the air supply quantity and the noise at the same time by increasing the air supply quantity to improve the refrigerating/heating effect; but if the noise reduction index is satisfied, the performance of the air conditioner is limited to a certain extent. These problems are particularly evident in special application scenarios such as libraries, wards, rooms of insomniacs, etc. That is, the conventional air conditioner has a problem of high noise when the air supply amount is large.

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, the wire rope 4233 is wound on the drum 4232, one end thereof is fixedly connected to the drum 4232, and the other end thereof is fixedly connected to a 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 at the inner side and between the two movable impellers 422a and 422b, and the elastic members 424 are configured to elastically deform to store elastic potential energy when the movable impeller 422a is contracted with respect to the fixed impeller 421 or when the movable impeller 422b is contracted with respect to the movable impeller 422 a. The expanded state and the contracted state of the cross flow fan are shown in fig. 11 and 12. As shown in fig. 13, when the cross-flow fan needs to shrink, the second driving motor 4231 drives the drum 4232 to retract the steel wire rope 4233, the outer movable impeller 422b shrinks under the compression spring driven by the steel wire rope 4233 and guided by the extension shaft 412, after shrinking to a certain stroke, the movable impeller 422b drives the inner movable impeller 422a to shrink, and finally, the two movable impellers shrink and are sleeved on the outer side of the fixed impeller 421. When the second driving 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 under 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 restriction edge 4212 provided on the fixed impeller 421 and the restriction edge 4221 provided on the inner movable impeller 422 a.

The above-described arrangement describes an example of the telescopic driving mechanism 423, and of course, the telescopic driving mechanism 423 may be variously implemented, for example, if there is a concern that the conductive slip ring wears out faster and the maintenance cost is higher, the motor may be provided with a battery to supply power to the motor, the indoor unit may be configured to be periodically connected to the battery to supply power to the battery, and the telescopic driving mechanism may be variously implemented, but it is only necessary to enable the second driving motor 4231 to operate normally and not to hinder the rotation of the impeller set 42.

In particular, after the air supplementing quantity is increased, the air quantity flowing into the heat exchanger 3 in unit time is increased, so that the heat exchange efficiency of the air conditioner is also improved, and the heating/refrigerating performance of the air conditioner is further improved.

In summary, by providing the air supply unit 5, the amount of air supply is increased, and the sum of the noise generated by the normal operation of the air supply fan 52 and the air blower 4 is far lower than the noise generated by the high-speed operation of the air blower 4 alone, so that the noise generated when the air conditioner outputs a large amount of air is reduced. The new air pipe 56 and the purification module 55 are added, so that the suspended corner air conditioner indoor unit has both the fresh air function and the purification function. The wind path pipeline 54 is added, so that the wind direction of the air supplementing machine 52 is changed, and the air supplementing effect is better. The humidifying water tank 2 is added, so that the design of the internal structure of the shell 1 is reduced, a middle compartment baffle is not needed, and the manufacturing is easier. The humidifying function of the suspension angle air conditioner is further expanded by the humidifying water tank 2, in addition, when the air flow after the heat exchange between the air blower 4 and the heat exchanger 3 flows through the humidifying water tank 2 during operation, the temperature of the air flow is regulated by the humidifying water tank 2, so that the aim of soft air outlet can be achieved, and the influence on user experience caused by supercooling or overheating of the air outlet is prevented. The impeller group 42 of the cross-flow fan is arranged to stretch and retract along the axial direction of the first driving motor 41, so that the vertical air outlet height of the air conditioner indoor unit can be controlled, the air conditioner indoor unit can be adjusted according to the actual installation position of the air conditioner and the height parameters of a user, the effects of no head blowing and no leg blowing are achieved, and the user experience is further improved.

For example, in another alternative embodiment, the cross-flow fan may be combined in other ways, provided that the impeller assembly 42 is axially retractable with respect to the first drive motor 41, without departing from the principles of the present invention. For example, the first driving motor 41 may also be a general motor, and accordingly the impeller assembly 42 includes only one fixed impeller 421 and a plurality of movable impellers 422a and 422b. For another example, the first driving motor 41 may be guided by providing a slide rail between the movable impeller 422a and the fixed impeller 421 or between the movable impeller 422a and the movable impeller 422b, instead of the extension shaft 412. For another example, only one movable impeller 422a may be provided for each fixed impeller 421, or a plurality of movable impellers may be provided.

For example, in another alternative embodiment, the atomizing element 21 may employ any atomizing element commonly used in the art, in addition to an ultrasonic atomizer, so long as the atomizing means is capable of generating water mist. Such as an electric heater or the like may also be employed.

For example, in another alternative embodiment, the rotary joint 563 may be replaced by a movable joint commonly used in pipeline connection, which can also achieve that when the two sections of fresh air pipes 56 are loosened, the two sections of fresh air pipes 56 can be relatively rotated, and when the two sections of fresh air pipes are placed at a reasonable angle, the movable joint is screwed down, so that the two sections of fresh air pipes 56 are firmly connected.
