Therefore, the invention changes the air inlet area at the first air port 15 and adjusts the air inlet amount at the first air port 15 by arranging the throat guiding section 20 and the guide plate 30 matched with the throat guiding section 20.
Further preferably, the air conditioner includes a bottom case 40 disposed within the casing 100, a first side of the baffle 30 is rotatably disposed on the bottom case 40, and a second side of the baffle 30 is for abutting against a free side of the throat intake section 20.
Specifically, a first rotating shaft 21 is arranged on a first side of the throat introduction section 20 to be movably connected with the lower side of the volute 11 through the first rotating shaft 21, a free side of the throat introduction section 20 is a second side of the throat introduction section 20 far away from the first side, and the first side of the throat introduction section 20 is located on one side of the second side far away from a supporting base plane of the air conditioner; the first side of the air deflector 30 is provided with a second rotating shaft 31 to be movably connected with the bottom case 40 through the second rotating shaft 31, and the second side of the air deflector 30 is located on the side of the first side away from the supporting base plane of the air conditioner, that is, on the side of the first side close to the throat introduction section 20.
Wherein, the first rotating shaft 21 and the second rotating shaft 31 can be driven by a motor respectively.

Because the rotating speed of the fan blade 13 is very high, the gas flow velocity at the volute introduction section 20 is also very high, when the gap between the second side of the volute introduction section 20 and the outer peripheral surface of the fan blade 13 is large, the air inlet area at the first air port 15 is large, the air inlet air volume is large, and the air flow is easy to generate turbulent vortex, so that the vortex noise is increased, therefore, the volute introduction section 20 needs to rotate clockwise to reduce the gap between the second side of the volute introduction section 20 and the outer peripheral surface of the fan blade 13, and the guide plate 30 needs to rotate anticlockwise to be used for being abutted against the volute introduction section 20.

Because the rotating speed of the fan blades 13 is low when the wind shield is low, the gas flow speed at the volute introduction section 20 is low, when the gap between the second side of the volute introduction section 20 and the outer peripheral surface of the fan blades 13 is small, the air inlet area at the first air inlet 15 is small, the air inlet amount is insufficient, and the fan 10 is prone to low-speed surge, the volute introduction section 20 needs to rotate anticlockwise to increase the gap between the second side of the volute introduction section 20 and the outer peripheral surface of the fan blades 13, and the guide plate 30 needs to rotate clockwise to be abutted to the volute introduction section 20.
Specifically, according to experimental data, an optimal volute inlet angle and a guide plate inclination angle matched with the volute inlet angle are matched for the upper air outlet low-wind-shield mode, so that the air inlet area is increased, the air inlet amount is increased, and the problem that the fan 10 is prone to low-speed surge is solved.
Preferably, the first tuyere 15 is located below the accommodating cavity 14, and when the first tuyere 15 is used for low-windshield air intake, an included angle between the extending direction of the throat introduction section 20 and the vertical direction is a second throat introduction angle C, wherein the second throat introduction angle C is 46-51 °; correspondingly, the angle between the extending direction of the air deflector 30 and the vertical direction is a second air deflector inclination angle D, and the second air deflector inclination angle D is 21 ° to 24 °.

At this time, the volute introduction section 20 rotates counterclockwise to the maximum opening degree so that the gap between the second side of the volute introduction section 20 and the outer peripheral surface of the fan blade 13 is maximized, and the guide plate 30 rotates clockwise to be used for abutting against the volute introduction section 20, and at this time, the volute introduction angle of the volute introduction section 20 and the guide plate inclination angle of the guide plate 30 are the optimal angles in the downward air-out mode, so that the air-out area at the first air port 15 is maximized, and the air-out volume of downward air-out is increased.
Since the above-mentioned baffle 30 is a flat plate, the extending direction of the baffle 30 refers to the included angle between any one of the two side plate surfaces of the baffle 30 and the vertical direction.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:

The relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. 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.
