Accordingly, since the second air supply opening 6 is used for outputting the wind power of the axial flow fan 3, the second air supply opening 6 may be configured to be circular, and when air is supplied through the first air supply opening 5 and the second air supply opening 6 respectively, since the directions of air supply by the cross-flow impeller 1 and the axial flow fan 3 are different, the air passages corresponding to the cross-flow impeller 1 and the axial flow fan 3 may be configured to be communicated with each other or to be separated from each other, which is not particularly limited herein.

Specifically, the straight line segment 7 corresponding to the airway in the present embodiment is a linear tubular structure.

Taking the example of a vertical arrangement of the corresponding straight section 7 of the wind tunnel, the present embodiment preferably arranges the air intake 4 and the first air supply outlet 5 on opposite sides of the straight section 7, so that the cross-flow impeller 1 can better perform air suction and correspondingly wind conveyance, wherein the air intake 4 and the first air supply outlet 5 can be arranged at a predetermined central angle with respect to the wind tunnel, for example: the central angle may be 120 ° to 180 °, and is not particularly limited herein.

As shown in fig. 2, when the air inlet 4 and the first air supply outlet 5 are disposed on opposite sides of the straight line section 7 (the central angle is 180 °), the air passing through the evaporator and the air inlet 4 can be delivered into the tubular vane 1 from the left side of the air duct, and the air output from the tubular vane 1 can be output from the first air supply outlet 5 along the right side, so that the air output from the second air supply outlet 6 is vertically upward when the second air supply outlet 6 is located at the upper end of the air duct and the rotary drive mechanism 2 is located at the lower end of the air duct, whereas the air output from the second air supply outlet 6 is vertically downward.

Specifically, in the actual design, the position of the second air supply outlet 6 can be adaptively designed through the corresponding bent section 8 of the air duct according to the air supply requirement, as further shown in fig. 2, the first air supply outlet 5 and the second air supply outlet 6 can be designed to be arranged along the corresponding axial direction of the cross flow impeller 1, so that the air supply directions of the first air supply outlet 5 and the second air supply outlet 6 are the same, but the air volume and the speed of the air supplied by the cross flow impeller 1 are usually larger than those of the axial flow fan 3 which coaxially rotates with the cross flow impeller, and the experience of obtaining the wind power at the same position in the relative air supply direction is also different.

In addition, the position of the second air supply outlet 6 can be additionally designed through the corresponding bent section 8 of the air channel, so that the air supply directions of the first air supply outlet 5 and the second air supply outlet 6 are different, and air is supplied to other directions through the second air supply outlet 6, and the diversification of the air supply modes is realized.

Preferably, as shown in fig. 4, each blade 102 on the cross-flow impeller 1 in the present embodiment has a wave shape, and the wave crests and the wave troughs of two adjacent blades 102 correspond to each other.

Specifically, when each blade 102 is designed, the blade 102 can be designed to be in a wave shape along the axial direction, and when the mounting structure of each blade 102 is designed, each blade 102 is designed to be a plurality of segments along the axial direction, the end parts of two adjacent segments are connected through a transfer ring 103, so that the stability of the whole structure of the cross-flow impeller 1 is improved, and the wave crests and the wave troughs of the two adjacent segments arranged along the circumference are designed to correspond to each other, so that the wave crests and the wave troughs are correspondingly arranged between the adjacent blades 102 forming the whole cross-flow impeller 1; therefore, when the through-flow impeller 1 rotates, airflow enters the interior from the open position of the through-flow impeller 1, and when the airflow is discharged from the wavy blades 102, the discharged direct-current wind is changed into turbulent wind because the direct-current airflow passes through the wave troughs and wave crests of the blades 102, the diffusion range of the wind direction is enlarged, and the direct blowing phenomenon of the wind power is reduced; in addition, because the blades 102 have wave crests and wave troughs, when the direct current wind enters the through-flow impeller 1, the direct current wind passes through smooth high and low surfaces, and thus the wind whistling noise generated when the wind passes through the plane is greatly reduced.

Therefore, when the cross flow impeller 1 is used for air conditioner to supply air to the indoor, turbulent air is conveyed, the turbulent air cannot directly blow to the body surface of a human body, and no wind whistle noise is generated in the air supply process of the cross flow impeller 1, so that the comfortable experience of household personnel in using the air conditioner is greatly increased.

Preferably, referring to fig. 5, the embodiment of the present invention further provides an air conditioner, which includes a casing 9, and the air supply structure of the air conditioner as described above is installed in the casing 9; the shell 9 is provided with a first air outlet 10 and a second air outlet 11, and air guide structures are arranged at the first air outlet 10 and the second air outlet 11, wherein the air guide structures can be preferably a plurality of air guide plates 12 rotatably installed at the first air outlet 10 and the second air outlet 11, and the air guide plates 12 can be connected with a driving motor, so that the corresponding first air outlet 10 and the corresponding second air outlet 11 can be opened or closed by the air guide plates 12 under the driving of the driving motor; the first air outlet 10 corresponds to the first air supply outlet 5, and the second air outlet 11 corresponds to the second air supply outlet 6.

Specifically, as shown in fig. 5, the present embodiment illustrates a structural design in which the first supply port 5 and the second supply port 6 are arranged in the axial direction of the axial flow impeller 1. Because the cross-flow impeller 1 is vertically arranged, the first air supply outlet 5 is positioned at the lower side of the second air supply outlet 6, and the first air outlet 10 is positioned at the lower side of the second air outlet 11. Thus, when the axial flow fan 3 is driven by the rotary drive mechanism 2 to rotate together with the cross-flow impeller 1, the first air blowing port 5 outputs wind power generated when the cross-flow impeller 1 rotates, and the second air blowing port 6 outputs wind power generated when the axial flow fan 3 rotates, but the first air outlet 10 and the second air outlet 11 independently or simultaneously blow air to the indoor environment under the control of the air guide structure. In the structure shown in fig. 5, a state is specifically shown in which the air deflector corresponding to the first air outlet 10 is opened and supplies air to the room, and the air deflector corresponding to the second air outlet 11 is closed and stops supplying air to the room.

Because the air conditioner that this embodiment shows has adopted above-mentioned air supply structure, not only greatly reduced the design cost of air conditioner, reduced the occupation of current air supply structure to the interior finite space of air conditioner, but also accessible wind-guiding structure control first air outlet 10, second air outlet 11 air supply to indoor environment alone or simultaneously, satisfied the house personnel to the demand of diversified air supply form, strengthened corresponding comfortable nature experience of using the air conditioner.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
