Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 to 3, the present invention provides an air conditioner including: the air inlet component 20, the evaporator 40, the fan 30 and the air outlet component 10 are sequentially arranged along the airflow flowing direction; the fan 30 comprises a volute 31, a volute tongue 32 and a fan blade part 33 which is rotatably arranged, the volute 31 and the volute tongue 32 jointly enclose a mounting cavity for mounting 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 is ((34-36) + (3-5). times.n) piece, n is (D-110)/10, when (D-110)/10 is decimal, n is integer part of decimal.
The air conditioner comprises an air inlet component 20, an evaporator 40, a fan 30 and an air outlet component 10 which are sequentially arranged along the flowing direction of air flow; the fan 30 comprises a volute 31, a volute tongue 32 and a fan blade part 33 which is rotatably arranged, the volute 31 and the volute tongue 32 jointly enclose a mounting cavity for mounting 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 is ((34-36) + (3-5). times.n) piece, n is (D-110)/10, when (D-110)/10 is decimal, n is integer part of decimal, namely, the part after the decimal point is cut is rounded. Therefore, by controlling the relationship between the outer diameter of the fan blade part and the number of the blades, the energy consumption of the air conditioner is reduced as much as possible on the premise of ensuring that the air supply quantity and the air supply distance are not attenuated, and the problem of high energy consumption of the air conditioner in the prior art is solved.
Specifically, under the condition of the same noise value, in order to reduce the energy consumption of the air conditioner (namely, reduce the rotating speed of the fan blade part 33), ensure that the air volume is not attenuated and increase the air supply distance, the number Z of the fan blades can be increased by 3 to 5 blades when the outer diameter D of the fan blade part 33 is increased by 10 mm.
Preferably, the length of the fan blade part is L, wherein L is more than or equal to 900mm and less than or equal to 950mm, D is more than or equal to 110mm and less than or equal to 115mm, and Z is more than or equal to 34 and less than or equal to 36.

Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
In the description of the present application, it is to be understood that the orientation or positional relationship indicated by the directional terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc., are generally based on the orientation or positional relationship shown in the drawings, and are used for convenience of description and simplicity of description only, and in the case of not making a reverse description, these directional terms do not indicate and imply that the device or element being referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore, should not be considered as limiting the scope of the present application; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship 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 of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of protection of the present application is not to be construed as being limited.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
