[0035] Figure 1 is a schematic flow chart of a control method of an air conditioner 10 according to an embodiment of the present invention, and Figure 2-6 The present invention provides a control method for an air conditioner 10, wherein the air conditioner 10 comprises two side-by-side air outlet columns 100, and each air outlet column 100 is provided with an air outlet 110 on its front side. The control method comprises: step S11, controlling the two air outlet columns 100 to have at least different air outlet speeds and different air outlet angles, so that a plurality of areas with different wind sensations are provided indoors.

[0036] In this embodiment, the two air outlet columns 100 are controlled to have at least different wind speeds and different air outlet angles, so that the room has a plurality of areas with different wind sensations. Users can select corresponding areas according to their own usage requirements, and the different needs of different users can be met at the same time, that is, the diversified usage requirements of different users can be met at the same time, thereby achieving the purpose of improving user experience.

[0037] like Figure 1As shown, the control method further includes: step S12, sending image information and wind information of each indoor area to the user.

[0038] In this embodiment, the air conditioner 10 sends image information and wind information of each indoor area to the user. After the user receives the above image information and wind information, each user can find the area suitable for him or her more conveniently, quickly and accurately, thereby further improving the user experience.

[0039] In some optional embodiments of the present invention, the wind sensation includes speed. Specifically, the speed is the actual wind speed felt by the user.

[0040] In some other optional embodiments of the present invention, the wind sensation includes temperature.

[0041] In some other optional embodiments of the present invention, the wind sensation includes speed and temperature. Specifically, the speed is the actual wind speed felt by the user.

[0042] In some optional embodiments of the present invention, the control method also includes: in response to an enveloping air outlet mode instruction issued by a user, controlling the two air outlet columns 100 to have at least different air outlet speeds and different air outlet angles, so that the actual air outlet of the air conditioner 10 can be deflected to one side and thus point to the desired enveloping air outlet direction.

[0043] In some alternative embodiments of the present invention, the control method further includes: when the preset automatic start conditions of the surrounding air outlet mode are met, the surrounding air outlet mode is automatically started, and the two air outlet columns 100 are controlled to have at least different air outlet speeds and different air outlet angles, so that the actual air outlet of the air conditioner 10 can be deviated to one side and point to the desired surrounding air outlet direction.

[0044] In some optional embodiments of the present invention, the control of the two air outlet columns 100 to have different air outlet speeds and different air outlet angles includes: controlling the two air outlet columns 100 to discharge heat exchange air inward, and controlling the air outlet column 100 on one side to execute a first air outlet speed, and at the same time controlling the other air outlet column 100 to execute a second air outlet speed, wherein the second air outlet speed is greater than the first air outlet speed, so that the room has a windless area 410, a mixed air area 420 and a heat exchange air area 430.

[0045] Specifically, when both air outlet columns 100 discharge heat exchange air inward, multiple areas with different wind sensations include a mixed air area, an insensitive air area, and a heat exchange air area. The mixed air area is the intersection of the air outlet areas of the two air outlet columns 100, and the air blown out of the two air outlet columns 100 is mixed together in the intersection area. In this embodiment, the mixed air area is heat exchange air, and the actual wind speed in the mixed air area is greater than the actual wind speed in the heat exchange air area. The actual wind speed in the insensitive area is the smallest.

[0046] In some other optional embodiments of the present invention, the control of the two air outlet columns 100 to have different air outlet speeds and different air outlet angles includes: controlling the two air outlet columns 100 to discharge non-heat exchange air inward, and controlling the air outlet column 100 on one side to execute a first air outlet speed, and at the same time controlling the other air outlet column 100 to execute a second air outlet speed, wherein the second air outlet speed is greater than the first air outlet speed, so that the room has a windless area, a mixed air area and a non-heat exchange air area.

[0047] Specifically, the non-heat exchange air is indoor air or outdoor fresh air. When both air outlet columns 100 discharge non-heat exchange air inward, multiple areas with different wind sensations include a mixed air area, an insensitive air area, and a non-heat exchange air area. The mixed air area is the intersection of the air outlet areas of the two air outlet columns 100, and the air blown out of the two air outlet columns 100 is mixed together in the intersection area. In this embodiment, the mixed air area is non-heat exchange air, and the actual wind speed in the mixed air area is greater than the actual wind speed in the non-heat exchange air area. The actual wind speed in the insensitive area is the smallest.

[0048] In some preferred embodiments of the present invention, the controlling of the two air outlet columns 100 to have at least different air outlet speeds and different air outlet angles includes: controlling the two air outlet columns 100 to have different air outlet speeds, different air outlet types and different air outlet angles, the air outlet types including heat exchange air and non-heat exchange air, so that the room has a windless area and a mixed air area, and also has a heat exchange air area or a non-heat exchange air area.

[0049] Specifically, the non-heat exchange air is indoor air or outdoor fresh air.

[0050] In this embodiment, since the two air outlet columns 100 supply air in a differentiated manner, one air outlet column 100 supplies heat exchange air, and the other air outlet column 100 supplies non-heat exchange air. The above two types of air are mixed together in the overlapping air outlet area of ​​the two air outlet columns 100, forming a "soft" wind in the mixed air area. Therefore, the user will not have a strong sense of cold or heat in the overlapping air outlet area, and the wind speed in this area is relatively high, thereby improving the user's comfortable air supply experience. In addition, compared with the method in which two air outlet columns 100 simultaneously supply heat exchange air or non-heat exchange air, the method in which one air outlet column 100 supplies heat exchange air and the other air outlet column 100 supplies non-heat exchange air, which is adopted in this embodiment, can make the differentiation of various indoor areas more significant, thereby further improving the user's experience.

[0051] Furthermore, if Figure 3 and Figure 4As shown, in some optional embodiments of the present invention, the control of the two air outlet columns 100 to have different air outlet speeds, different air outlet types and different air outlet angles includes: controlling the two air outlet columns 100 to discharge air inward, and controlling the air outlet column 100 on one side to discharge non-heat exchange air and execute the first air outlet speed, while controlling the other air outlet column 100 to discharge heat exchange air and execute the second air outlet speed, the second air outlet speed is greater than the first air outlet speed, so that the room has a windless area 410, a mixed air area 420 and a heat exchange air area 430. Specifically, the mixed air area is a soft wind area. When the cooling operation is in progress, the heat exchange air area is hot air; when the cooling operation is in progress, the heat exchange air area is cold air.

[0052] For example: Figure 3 As shown, the two air outlet columns 100 are controlled to discharge air inwards, and the right air outlet column 100 is controlled to discharge non-heat exchange air and execute the first air outlet speed, while the left air outlet column 100 is controlled to discharge heat exchange air and execute the second air outlet speed, the second air outlet speed is greater than the first air outlet speed, and the left high wind speed is used to deflect the wind direction to the right, forming an embracing air supply to the right. Each user can select different areas according to their own area.

[0053] like Figure 4 As shown, the two air outlet columns 100 are controlled to discharge air inwards, and the air outlet column 100 on the left is controlled to discharge non-heat exchange air and execute the first air outlet speed, while the air outlet column 100 on the right is controlled to discharge heat exchange air and execute the second air outlet speed, the second air outlet speed is greater than the first air outlet speed, and the right high wind speed is used to deviate the wind direction to the left, forming an embracing air supply to the left.

[0054] In some other optional embodiments of the present invention, the control of the two air outlet columns 100 to have different air outlet speeds, different air outlet types and different air outlet angles includes: controlling the two air outlet columns 100 to discharge air inward, and controlling the air outlet column 100 on one side to discharge heat exchange air and execute the third air outlet speed, while controlling the other air outlet column 100 to discharge non-heat exchange air and execute the fourth air outlet speed, wherein the fourth air outlet speed is greater than the third air outlet speed, so that there are no wind feeling areas, mixed air areas and non-heat exchange air areas in the room. Specifically, the mixed air area is a soft wind area. When the cooling operation is in progress, the heat exchange air area is hot air; when the cooling operation is in progress, the heat exchange air area is cold air.

[0055] like Figure 3-4 As shown, in some embodiments of the present invention, each of the air outlets 110 is provided with an air guiding device 111; the air guiding device 111 includes at least one air guiding plate for guiding the wind laterally.

[0056] For example, the wind guide device 111 includes one wind guide plate, two wind guide plates, three wind guide plates, or four wind guide plates.

[0057] Furthermore, each of the air guide plates is connected to a driving motor to drive the movement of each air guide plate.

[0058] Preferably, the air guide device 111 includes two air guide plates. The air conditioner 10 has four air guide plates in total, and the four air guide plates are individually controlled by the driving motors.

[0059] In some optional embodiments of the present invention, the air outlet column 100 with a higher air outlet speed has at least two air guide plates for lateral air guiding, controlling a channel with a smaller front and a larger rear portion to be formed between the two air guide plates, and the front edge of the air guide plate away from the other air outlet column 100 is located in front of the front edge of the other air guide plate.

[0060] Specifically, the width of the channel gradually decreases along the flow direction of the airflow.

[0061] In this embodiment, through the above-mentioned setting, the air outlet speed of the air outlet column 100 with a larger air outlet speed can be increased, so that the air supply distance of the air outlet column 100 is longer, and the area of ​​the windless area and the mixed wind area can be larger, and the wind speed in the mixed wind area can also be made higher.

[0062] Furthermore, the air outlet column 100 with a smaller air outlet speed has at least two air guide plates for lateral air guide, and the two air guide plates are controlled to be parallel to each other and face toward the other air outlet column 100 .

[0063] In some optional embodiments of the present invention, the control method further includes: obtaining a user position of the user, and sending the user position to the user. In this embodiment, through the above settings, it is easier for the user to find the area with a specific wind feeling that he needs.

[0064] The controlling of the two air outlet columns 100 to have at least different air outlet speeds and different air outlet angles comprises the following steps:

[0065] Step S21, after determining the air outlet direction and air outlet speed of the air outlet column 100 with a larger air outlet speed, keep the air outlet direction and air outlet speed of the air outlet column 100 with a larger air outlet speed unchanged.

[0066] Step S22, according to preset conditions, controls the air outlet speed and air outlet direction of another air outlet column 100, and makes the air outlet speed of another air outlet column 100 always smaller than the air outlet speed of the air outlet column 100 with a larger air outlet speed, so as to change the position and / or size of multiple areas with different wind sensations.

[0067] In this embodiment, by changing the air outlet speed of the air outlet column 100 with a lower air outlet speed, the positions and / or sizes of multiple areas with different wind sensations can be changed.

[0068] like Figure 3-4As shown, in some optional embodiments of the present invention, a heat exchanger 120 and a fan 130 are provided in each of the air outlet columns 100. The air conditioner further includes a flow control device, which is configured to control the two heat exchangers 120 to work simultaneously or only one of the heat exchangers 120 to work.

[0069] Since each air outlet column 100 has a heat exchanger 120, the two heat exchangers 120 are independent, and the two heat exchangers 120 can work at the same time, or not work at the same time, or only one works and the other does not work. Therefore, when only one of the two heat exchangers 120 works and the other does not work, one air outlet column 100 outputs heat exchange air, and the other air outlet column 100 outputs non-heat exchange air or no air, so that the two air outlet columns 100 can achieve differentiated air supply.

[0070] Furthermore, if Figure 5 As shown, two heat exchangers 120 are arranged in parallel. The flow path controller includes a three-way valve 170. The three-way valve 170 includes three openings, namely a first opening, a second opening and a third opening. The first opening is connected to the four-way valve 180, and the second opening and the third opening are respectively connected to the two heat exchangers 120. By controlling the on-off of the second opening and the third opening of the three-way valve 170, the on-off of the working fluid flow path in each heat exchanger 120 is controlled, and the execution action is stable and reliable. In other words, by controlling the opening of the three-way valve 170, the refrigerant can flow to one air outlet column 100 alone and to two air outlet columns 100 at the same time, thereby realizing the function of separate control of the double air outlet columns 100.

[0071] In some embodiments of the present invention, the air conditioner 10 further includes a throttling device 140. The throttling device 140 is located upstream of the heat exchanger 120. The throttling device 140 is used to control the amount of the working medium entering the heat exchanger 120. The throttling device 140 generally includes a capillary tube, a mechanical expansion valve, an electronic expansion valve or a solenoid valve, etc. Preferably, the throttling device 140 is a solenoid valve.

[0072] In some embodiments of the present invention, the air conditioner 10 further includes a compressor 160, a condenser 150 and a four-way valve 180 between the three-way valve 170 and the compressor 160 connected in series, and the throttling device 140 is connected to the condenser 150. The compressor 160 includes a liquid storage tank 190.

[0073] like Figure 3-4 As shown, further, in some optional embodiments of the invention, two air outlet columns 100 are symmetrically arranged about a vertical reference plane extending forward and backward. The symmetrically arranged air outlet columns 100 make the vertical air conditioner indoor unit look stable and in line with the aesthetic taste of Chinese people.

[0074] The two air outlets 110 of the air conditioner 10 are symmetrically arranged with respect to a vertical reference plane extending front to back.

[0075] The two air outlet columns 100 are arranged at intervals to form an air induction interval 200 between the two air outlet columns 100. When the two air outlet columns 100 discharge air forward, the air in the air induction interval 200 is driven forward by negative pressure, so that the air is mixed with the air blown out by the two air outlet columns 100, and during cooling, the air outlet temperature is increased, so that the wind is not too "hard" and the effect of "soft" wind is produced.

[0076] In some optional embodiments of the invention, the air inlet interval 200 only includes an air inlet section and an air outlet section connected to each other. The width of the air outlet section gradually increases along the flow direction of the air flow. The width of the air inlet section gradually decreases along the flow direction of the air flow. The above-mentioned arrangement of the air inlet interval 200 is conducive to the air entering the rear side of the air inlet interval 200 and is also conducive to the air in the air inlet interval 200 flowing forward.

[0077] Figure 3 is a schematic cross-sectional view of an air conditioner according to an embodiment of the present invention, referring to Figure 4-6 The present invention further provides an air conditioner 10, which includes a controller 300. The controller includes a memory 310 and a processor 320. The memory 310 stores a control program, which is used to implement the control method of the air conditioner as described in any of the above embodiments when executed by the processor 320.

[0078] It should be noted that the specific structure of the air conditioner 10 includes the structure of the air conditioner in any one of the embodiments of the above control method, and will not be repeated.

[0079] Multiple exemplary embodiments of the present invention, however, without departing from the spirit and scope of the present invention, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention. Therefore, the scope of the present invention should be understood and identified as covering all these other variations or modifications.
