The air conditioner of the invention comprises an air inlet component 20, an evaporator 40, a fan 30 and an air outlet component 10 which are sequentially arranged along the airflow flowing direction; the fan 30 comprises a volute casing 31, a volute tongue 32 and a fan blade part 33 which is rotatably arranged, the volute casing 31 and the volute tongue 32 jointly enclose an installation cavity for installing the fan blade part 33, the outer diameter of the fan blade part 33 is D, and the number of blades in the fan blade part 33 is Z; wherein, Z= ((34-36) + (3-5) x n) piece, n= (D-110)/10, when (D-110)/10 is the decimal, n takes the integer part in the decimal, namely the part after the decimal point is cut off and rounded. Therefore, the invention reduces the energy consumption of the air conditioner as much as possible and solves the problem of larger energy consumption of the air conditioner in the prior art by controlling the relation between the outer diameter of the fan blade part and the number of the fan blades on the premise of ensuring that the air quantity and the air supply distance are not attenuated.
Specifically, in order to reduce the energy consumption of the air conditioner (i.e., reduce the rotational speed of the fan blade member 33) while ensuring that the air volume is not attenuated and increasing the air supply distance under the same noise value, the number Z of blades may be increased by 3 to 5 pieces every 10mm of the outer diameter D of the fan blade member 33.

In the description of the present application, it should be understood that, where azimuth terms such as "front, rear, upper, lower, left, right", "transverse, vertical, horizontal", and "top, bottom", etc., indicate azimuth or positional relationships generally based on those shown in the drawings, only for convenience of description and simplification of the description, these azimuth terms do not indicate and imply that the apparatus or elements referred to must have a specific azimuth or be constructed and operated in a specific azimuth, and thus should not be construed as limiting the scope of protection of the present application; the orientation word "inner and outer" refers to inner and outer relative to the contour of the respective component itself.
Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
In addition, the terms "first", "second", etc. are used to define the components, and are merely for convenience of distinguishing the corresponding components, and unless otherwise stated, the terms have no special meaning, and thus should not be construed as limiting the scope of the present application.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
