According to some embodiments of the present invention, the supply port 120 may be an indoor supply port 120 communicating with the indoor. That is, the air supply port 120 may be communicated with the room, the air in the room may enter the air supply channel 140 from the air supply port 120, the air flow entering the air supply channel 140 may be heat-neutralized with the air flow after heat exchange, and the air flow after heat neutralization may be pressurized by the second wind wheel 420 to realize long-distance air supply.
In some embodiments of the present invention, as shown in fig. 5-7, a functional module 50 for purifying and/or humidifying the airflow may be provided in the second wind wheel placement chamber 320 and/or at the air supply port 120, and the functional module 50 may be located in the airflow circulation path from the air supply port 120 to the second wind wheel placement chamber 320. Thereby, the air quality of the air flow blown out from the second wind wheel placement chamber 320 can be improved.
According to some embodiments of the invention, a second wind wheel placement cavity 320 is provided at least one of above, below, to the left and to the right of the first wind wheel placement cavity 310. That is, the second wind wheel placing chamber 320 may be provided at one of the upper, lower, left and right sides of the first wind wheel placing chamber 310; the second wind wheel placing cavity 320 may be provided at two of the upper, lower, left and right sides of the first wind wheel placing cavity 310; the second wind wheel placing cavity 320 may be further provided at three of the upper, lower, left and right sides of the first wind wheel placing cavity 310; of course, the second wind wheel placing chamber 320 may be disposed above, below, left and right of the first wind wheel placing chamber 310.

The second rotor placement chamber 320 is located above the first rotor placement chamber 310.
It should be noted that, indoor air may enter the heat exchange air duct 130 from the air inlet 110, and the air flow exchanges heat in the heat exchange air duct 130 through the heat exchanger 20. The air flow after heat exchange is divided into two parts, one part of the air flow flows into the second wind wheel placing cavity 320 above and is mixed with the air flow entering the second wind wheel placing cavity 320 from the air supplementing port 120, and finally the air flow is accelerated by the second wind wheel 420 and is blown out from the second air outlet 152; the other air flow after heat exchange flows into the first wind wheel placing cavity 310 below, and is accelerated by the first wind wheel 410 and then blown out from the first air outlet 151.

Under the action of the second wind wheel 420, the air flow blown out from the second air outlet 152 can be led to a far place, so as to realize long-distance air supply. The first wind wheel 410 can uniformly and stably blow out the air flow in the first wind wheel placing cavity 310 from the first air outlet 151, so as to realize close-range comfortable air supply. In addition, the air flow blown out from the second air outlet 152 can guide the air flow blown out from the first air outlet 151 to a relatively far position, which is beneficial to improving the cooling or heating efficiency of the air conditioner 100, and realizes the diversity and comfort of the air supply of the air conditioner 100.
In some embodiments of the present invention, the second wind wheel placement cavities 320 may be two and distributed on both upper and lower sides of the first wind wheel placement cavity 310. That is, one second wind wheel 420 may be provided at both upper and lower sides of the first wind wheel 410, respectively.
It should be noted that, indoor air may enter the heat exchange air duct 130 from the air inlet 110, and the air flow is divided into three flows after heat exchange of the heat exchanger 20. The upper air flow flows into the upper second wind wheel placing cavity 320, is mixed with the air flow flowing into the second wind wheel placing cavity 320 from the air supplementing channel 140, and is finally pressurized by the second wind wheel 420 and then blown out from the second air outlet 152; one air flow in the middle part flows into the first wind wheel placing cavity 310 in the middle, is pressurized by the first wind wheel 410 and is blown out from the first air outlet 151; the lower air flow flows into the lower second wind wheel placing cavity 320, is mixed with the air flow flowing into the second wind wheel placing cavity 320 from the air supplementing channel 140, and is finally pressurized by the second wind wheel 420 and then blown out from the second air outlet 152. Thus, the diversity of the air supply of the air conditioner 100 can be further improved, and accordingly, the air supply requirements of the air conditioner 100 in different working modes can be controlled and adjusted accordingly.
According to some embodiments of the present invention, as shown in fig. 2, the first wind wheel 410 and the second wind wheel 420 may be coaxially disposed, and the motor assembly 60 may include a dual-shaft motor, and the first wind wheel 410 and the second wind wheel 420 are respectively connected to two output shafts of the dual-shaft motor. That is, the central axis of the first wind wheel 410 and the central axis of the second wind wheel 420 may be located on the same line, and the first wind wheel 410 and the second wind wheel 420 respectively share one dual-shaft motor. Thereby, the layout and the assembly of the first wind wheel 410 and the second wind wheel 420 are facilitated, which is advantageous for compactification and rationalization of the structure of the air conditioner 100. Moreover, the first wind wheel 410 and the second wind wheel 420 can share a double-shaft motor, so that the production cost of the air conditioner 100 is reduced, and the air conditioner 100 is convenient to control and regulate.
According to some embodiments of the present invention, the minimum distance between the first wind wheel 410 and the second wind wheel 420 in the axial direction is L, which satisfies the following: l is more than or equal to 100mm. As shown in fig. 2, the first wind wheel 410 and the second wind wheel 420 may be coaxially disposed, and a minimum axial distance between the first wind wheel 410 and the second wind wheel 420 is not less than 100mm. Thereby, the layout and the assembly of the biaxial motor between the first wind wheel 410 and the second wind wheel 420 are facilitated, and the assembly efficiency of the air conditioner 100 is advantageously improved.
It should be noted that the central axes of the rotation shafts of the first wind wheel 410 and the second wind wheel 420 may not be located on the same straight line. For example, in some embodiments of the present invention, the motor assembly 60 may include a first driving motor through which the first wind wheel 410 is driven to rotate and a second driving motor through which the second wind wheel 420 is driven to rotate. Thus, the layout and assembly of the first wind wheel 410 and the second wind wheel 420 can be made more flexible and convenient. Moreover, the first wind wheel 410 and the second wind wheel 420 can be independently controlled, which is beneficial to improving the diversity of the air conditioner 100.
In some embodiments of the present invention, a first wind wheel 410 and two second wind wheels 420 may be disposed in the air conditioner 100, and the two second wind wheels 420 are disposed at the upper and lower ends of the first wind wheel 410, respectively. The first wind wheel 410 and the two second wind wheels 420 may be respectively provided with a corresponding first driving motor and a corresponding second driving motor for driving. The first rotor 410 may also share a dual shaft motor with one of the second rotors 420. For example, the first wind wheel 410 is coaxially disposed with the second wind wheel 420 above, and the first wind wheel 410 shares a double-shaft motor with the second wind wheel 420 above. The second wind wheel 420 located below is separately provided with a driving motor.
Of course, the first wind wheel 410 may be coaxially disposed with the second wind wheel 420 below, the first wind wheel 410 and the second wind wheel 420 below share a dual-shaft motor, and the second wind wheel 420 above is separately disposed with a driving motor. Therefore, the layout of the internal structure of the air conditioner 100 can be adjusted and designed according to the actual design requirement, which is beneficial to improving the design diversity of the air conditioner 100.
According to some embodiments of the present invention, the number of air outlets may be plural, each air outlet may be correspondingly provided with an inner layer air guiding strip and a rotatable outer layer air guiding plate, and rotation axes of the outer layer air guiding plates at two adjacent air outlets are vertically arranged. As shown in fig. 2 and fig. 4 to fig. 7, the air outlet includes a second air outlet 152 and a first air outlet 151 which are disposed at an upper and lower interval. The second air outlet 152 may be correspondingly provided with an outer layer air deflector extending in a horizontal direction, so that the second air outlet 152 may realize an up-and-down swing air supply effect. The first air outlet 151 may be correspondingly provided with an outer air deflector extending in a vertical direction, so that the first air outlet 151 may have a left-right swing air supply effect. Thereby, the diversity and comfort of the air supply of the air conditioner 100 can be further improved.
In other embodiments of the present invention, the air outlet may include a second air outlet 152, a first air outlet 151, and a second air outlet 152 sequentially disposed in the up-down direction. The first air outlet 151 may be provided with an outer air deflector extending in a vertical direction, so that a left-right swing air supply effect of the first air outlet 151 may be achieved. The second air outlets 152 on the upper and lower sides can be provided with an outer layer air deflector extending in the horizontal direction, so that the second air outlets 152 on the upper and lower sides can have an up-and-down swing air supply effect, and the air supply diversity of the air conditioner 100 is improved.
In some embodiments of the present invention, the area of the first air outlet 151 is S1, and the area of the second air outlet 152 is S2, which satisfies the following conditions: S2/(S1+S2) is less than or equal to 10% and less than or equal to 50%. As shown in fig. 2 and fig. 4 to 7, the area of the first air outlet 151 corresponding to the first wind wheel 410 is S1, and the area of the second air outlet 152 corresponding to the second wind wheel 420 is S2, which satisfies the following conditions: S2/(S1+S2) is less than or equal to 10% and less than or equal to 50%.
It should be noted that, the area of the second air outlet 152 is not set to be too large, so as not to affect the air outlet speed and the air supply distance of the second air outlet 152. The area of the second air outlet 152 is not set too small, so as not to affect the air supply amount of the second air outlet 152. Experiments prove that when the area S2 of the second air outlet 152 and the area S1 of the first air outlet 151 satisfy: when S2/(S1+S2) is less than or equal to 10% and less than or equal to 50%, the air conditioner 100 can have better air supply distance and air supply quantity, and the working performance of the air conditioner 100 is improved.
In some embodiments of the present invention, as shown in fig. 8, a pressure regulating member 70 may be disposed in the second wind wheel placement cavity 320, and an air outlet channel 710 is defined in the pressure regulating member 70, where the cross-sectional area of the second air outlet 152 is S2, and the cross-sectional area of the outlet end of the air outlet channel 710 is S3, so that: s2+.s3. That is, the cross-sectional area S2 of the second air outlet 152 and the cross-sectional area S3 of the outlet end of the air outlet channel 710 may satisfy: s2 > S3, or S2 < S3. Therefore, the second wind wheel placing cavity 320 can be internally provided with the tapered or gradually-expanded air outlet channel 710, so that the wind speed in the air outlet channel 710 can be changed, and the air supply diversity of the air conditioner 100 can be improved.
According to some embodiments of the present invention, as shown in fig. 8, the cross-sectional area of the air outlet passage 710 gradually decreases in the flow direction of the air flow. Therefore, when the airflow flows in the air outlet channel 710, the cross-street area of the air outlet channel 710 is gradually reduced, so that the airflow velocity in the air outlet channel 710 is gradually increased, thereby being beneficial to the air supply distance of the second air outlet 152.
According to some embodiments of the present invention, the second air outlet 152 may be disposed near the top end of the housing 10. As shown in fig. 2 and fig. 4 to fig. 7, the second air outlet 152 corresponding to the second wind wheel 420 may be disposed near the top end of the casing 10, and it should be noted that, when the air conditioner 100 operates in the non-wind-sensation operation mode, the second air outlet 152 located at the top end of the casing 10 may parabolic lead out the air flow upwards, so that the direct blowing of the air flow by the user is effectively avoided, and the air supply comfort and the user experience of the air conditioner 100 are improved.
In some embodiments of the present invention, the air conditioner 100 may be a split floor type air conditioner, or a split wall type air conditioner, or a ceiling type air conditioner, or a window type air conditioner, or a mobile type air conditioner. As shown in fig. 1 to 7, the air conditioner 100 may be a cabinet air conditioner 100. The air conditioner 100 is provided with a second wind wheel 420 and a first wind wheel 410 which are arranged at intervals along the up-down direction, and the front side of the shell 10 is provided with a corresponding second air outlet 152 and a corresponding first air outlet 151. Therefore, the cabinet air conditioner 100 can have air supply diversity, and the air supply comfort and the user experience of the cabinet air conditioner 100 are improved. It can be appreciated that when the air conditioner 100 is another type of air conditioner, the air conditioner 100 can have air supply diversity by arranging the first wind wheel placing cavity 310 and the second wind wheel placing cavity 320 in the air conditioner 100, and the working performance of the air conditioner 100 is improved.
In some embodiments of the present invention, the first wind wheel 410 may be one of a centrifugal wind wheel, a cross flow wind wheel, and an axial flow wind wheel, and the second wind wheel 420 may be one of a centrifugal wind wheel, a cross flow wind wheel, and an axial flow wind wheel. For example, a plurality of centrifugal wind wheels may be disposed in the air conditioner 100, or a plurality of cross flow wind wheels may be disposed in the air conditioner 100, or a plurality of axial flow wind wheels may be disposed in the air conditioner 100, or a centrifugal wind wheel and a cross flow wind wheel may be disposed in the air conditioner 100, or a centrifugal wind wheel and an axial flow wind wheel may be disposed in the air conditioner 100, or a cross flow wind wheel and an axial flow wind wheel may be disposed in the air conditioner 100, or a centrifugal wind wheel, a cross flow wind wheel and an axial flow wind wheel may be disposed in the air conditioner 100. Thereby, the diversity and flexibility of the design of the air conditioner 100 can be improved. Because the centrifugal wind wheel, the cross flow wind wheel and the axial flow wind wheel have different air supply distances and air supply volumes, corresponding wind wheel combination and arrangement can be selected according to actual air supply requirements in the design and manufacturing process of the air conditioner 100.
For example, the first rotor 410 may be a cross-flow rotor and the second rotor 420 may be a centrifugal rotor. At this time, the air flow from the air inlet 110 enters the heat exchange air duct 130, and a part of the air flow after heat exchange in the heat exchange air duct 130 enters the first wind wheel placing cavity 310 and flows out from the first air outlet 151 under the action of the cross flow wind wheel. The other part of the air flow after heat exchange enters the second wind wheel placing cavity 320 and is mixed with the air flow entering the air supplementing channel 140, and is blown out from the second air outlet 152 under the action of the centrifugal wind wheel.
Of course, the first wind wheel 410 may be a centrifugal wind wheel, and the second wind wheel 420 may be a cross-flow wind wheel. At this time, the air flow from the air inlet 110 enters the heat exchange air duct 130, and after heat exchange in the heat exchange air duct 130, the air flow partially enters the first wind wheel placing cavity 310 and flows out from the first air outlet 151 under the action of the centrifugal wind wheel. The other part of the air flow after heat exchange enters the second wind wheel placing cavity 320 and is mixed with the air flow entering the air supplementing channel 140, and the air flow is blown out from the second air outlet 152 under the action of the cross flow wind wheel.
