[0035] Figure 1 is a schematic flow chart of the control method of the air conditioner 10 according to an embodiment of the present application, and is combined with Figures 2-6 The present application provides a control method of an air conditioner 10, the air conditioner 10 comprising two side-by-side air outlet columns 100, and each air outlet column 100 is provided with an air outlet 110 on the front side. The control method comprises the following steps: S11, controlling two air outlet columns 100 to have at least different air outlet speeds and different air outlet angles, so as to make the indoor area have multiple wind feeling different areas.

[0036] In the present embodiment, the two air outlet columns 100 are controlled to have at least different air speeds and different air outlet angles, so as to make the indoor area have multiple wind feeling different areas. Users can select the corresponding area according to their own use requirements, and the different needs of different users can be met at the same time, that is, the diversified use requirements of different users can be met at the same time, so as to achieve the purpose of improving the user experience.

[0037] As Figure 1As shown, the control method further comprises: in step S12, sending image information and wind feeling information of each region in the indoor space to the user.

[0038] In the embodiment, the air conditioner 10 sends the image information and the wind feeling information of each region in the indoor space to the user, and after the user receives the image information and the wind feeling information, each user can more conveniently and accurately find a region suitable for himself, thereby further improving the user experience.

[0039] In some alternative embodiments of the present application, the wind feeling includes the temperature.

[0040] In some alternative embodiments of the present application, the wind feeling includes the temperature.

[0041] In some alternative embodiments of the present application, the wind feeling includes the temperature.

[0042] In some alternative embodiments of the present application, the control method further comprises: in response to the user issuing a ring-type air outlet mode instruction, 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 deviated to one side to point to the required ring-type air outlet direction.

[0043] In some alternative embodiments of the present application, the control method further comprises: when the preset ring-type air outlet mode automatic starting condition is met, automatically starting the ring-type air outlet mode, and 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 deviated to one side to point to the required ring-type air outlet direction.

[0044] In some alternative embodiments of the present application, the control method further comprises: in response to the user issuing a ring-type air outlet mode instruction, 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 deviated to one side to point to the required ring-type air outlet direction.

[0045] In some alternative embodiments of the present application, the control method further comprises: in response to the user issuing a ring-type air outlet mode instruction, 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 deviated to one side to point to the required ring-type air outlet direction.

[0046] In some preferred embodiments of the present application, the control of the two air outlet columns 100 to have at least different air outlet speeds and different air outlet angles comprises: 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 indoor space has a windless zone and a mixed air zone, and also has a heat exchange air zone or a non-heat exchange air zone.

[0047] Specifically, the non-heat exchange air is indoor air or outdoor fresh air. When the two air outlet columns 100 both blow non-heat exchange air to the indoor space, the multiple air feeling different zones include a mixed air zone, a windless zone, and a non-heat exchange air zone. The mixed air zone is the intersection zone of the air outlet zones of the two air outlet columns 100, and the air blown by the two air outlet columns 100 mixes together in the intersection zone. In this embodiment, the mixed air zone is filled with non-heat exchange air, and the actual air speed in the mixed air zone is greater than that in the non-heat exchange air zone. The actual air speed in the windless zone is the smallest.

[0048] In some preferred embodiments of the present application, the control of the two air outlet columns 100 to have at least different air outlet speeds and different air outlet angles comprises: 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 indoor space has a windless zone and a mixed air zone, and also has a heat exchange air zone or a non-heat exchange air zone.

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

[0050] In this embodiment, due to the differential air supply of the two air outlet columns 100, one air outlet column 100 blows heat exchange air, and the other air outlet column 100 blows non-heat exchange air, and the two kinds of air mix together in the air outlet overlapping area of the two air outlet columns 100, forming "soft" air in the mixed air zone. Therefore, in the air outlet overlapping area, the user will not have a strong cold or hot feeling, and the air speed in this area is relatively large, thereby improving the user's comfortable air supply experience. In addition, compared with the mode of blowing heat exchange air or non-heat exchange air by the two air outlet columns 100 at the same time, the mode of blowing heat exchange air by one air outlet column 100 and blowing non-heat exchange air by the other air outlet column 100 adopted in this embodiment can make the difference of each area in the indoor space more significant, thereby further improving the user's experience.

[0051] Further, as Figure 3 and Figure 4As shown, in some optional embodiments of the present invention, controlling the two air outlet columns 100 to have different air outlet speeds, different air outlet types, and different air outlet angles includes: controlling both air outlet columns 100 to outlet air inwards, controlling one air outlet column 100 to outlet non-heat exchange air at a first air outlet speed, while controlling the other air outlet column 100 to outlet heat exchange air at a second air outlet speed, the second air outlet speed being greater than the first air outlet speed, so that the room has a windless zone 410, a mixed air zone 420, and a heat exchange air zone 430. Specifically, the mixed air zone is a soft air zone. During cooling operation, the heat exchange air zone contains hot air; during cooling operation, the heat exchange air zone contains cold air.

[0052] For example: Figure 3 As shown, both air outlet columns 100 are controlled to outlet air inwards. The right air outlet column 100 is controlled to outlet non-heat exchange air at a first outlet speed, while the left air outlet column 100 is controlled to outlet heat exchange air at a second outlet speed. The second outlet speed is greater than the first outlet speed. By utilizing the higher left air speed, the airflow is deflected to the right, forming a wraparound airflow to the right. Each user can select a different area according to their own region.

[0053] like Figure 4 As shown, both air outlet columns 100 are controlled to outlet air inwards, and the left air outlet column 100 is controlled to outlet non-heat exchange air and execute the first outlet air speed, while the right air outlet column 100 is controlled to outlet heat exchange air and execute the second outlet air speed. The second outlet air speed is greater than the first outlet air speed. The high right air speed is used to deflect the air direction to the left, forming a wraparound air supply to the left.

[0054] In some alternative embodiments of the present invention, controlling the two air outlet columns 100 to have different air outlet speeds, different air outlet types, and different air outlet angles includes: controlling both air outlet columns 100 to outlet air inwards, controlling one air outlet column 100 to outlet heat exchange air and execute a third air outlet speed, while controlling the other air outlet column 100 to outlet non-heat exchange air and execute a fourth air outlet speed, wherein the fourth air outlet speed is greater than the third air outlet speed, so that the room has a windless zone, a mixed air zone, and a non-heat exchange air zone. Specifically, the mixed air zone is a soft air zone. During cooling operation, the heat exchange air zone contains hot air; during cooling operation, the heat exchange air zone contains cold air.

[0055] like Figures 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 lateral air guiding.

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

[0057] Further, each of the air deflector is connected with a driving motor to drive the air deflector to move.

[0058] Preferably, the air deflector device 111 comprises two air deflectors. The air conditioner 10 has four air deflectors in total, which are controlled individually by driving motors respectively.

[0059] In some optional embodiments of the present application, the air outlet column 100 with a larger air outlet speed has at least two air deflectors for lateral air deflection, the two air deflectors are controlled to form a channel with a front small and a rear large, and the front edge of the air deflector away from another air outlet column 100 is in front of the front edge of the air deflector of another air outlet column 100.

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

[0061] In the present embodiment, through the above-mentioned arrangement, the air outlet speed of the air outlet column 100 with a larger air outlet speed can be improved, so that the air supply distance of the air outlet column 100 is farther, and the area of the windless area and the mixed air area can be larger, and the air speed in the mixed air area can be larger.

[0062] Further, the air outlet column 100 with a smaller air outlet speed has at least two air deflectors for lateral air deflection, the two air deflectors are controlled to be parallel to each other and face another air outlet column 100.

[0063] In some optional embodiments of the present application, the control method further comprises: obtaining a user position of the user, and sending the user position to the user. In the present embodiment, through the above-mentioned arrangement, it is more convenient for the user to find the area with a specific air feeling that the user needs.

[0064] The control of the two air outlet columns 100 at least having 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, the air outlet direction and air outlet speed of the air outlet column 100 with a larger air outlet speed remain unchanged.

[0066] Step S22, according to a preset condition, the air outlet speed and air outlet direction of another air outlet column 100 are controlled, and the air outlet speed of another air outlet column 100 is 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 the multiple air feeling different areas.

[0067] In the present embodiment, by changing the air outlet speed of the air outlet column 100 with a smaller air outlet speed, the position and / or size of the multiple air feeling different areas can be changed.

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

[0069] Since each of the air outlet columns 100 is provided with a heat exchanger 120, two heat exchangers 120 are independent, and two heat exchangers 120 can work simultaneously, can not work simultaneously, or only one of the heat exchangers 120 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, thereby realizing differential air supply of the two air outlet columns 100.

[0070] Further, as shown, Figure 5 Two heat exchangers 120 are connected in parallel. The flow path controller comprises a three-way valve 170. The three-way valve 170 comprises three openings, namely a first opening, a second opening and a third opening. The first opening is connected with the four-way valve 180, and the second opening and the third opening are respectively connected with two heat exchangers 120. By controlling the opening and closing of the second opening and the third opening of the three-way valve 170, the opening and closing of the working medium flow path in each heat exchanger 120 are controlled, and the action is stable and reliable. That is, by controlling the opening degree of the three-way valve 170, the refrigerant can flow to one air outlet column 100 or two air outlet columns 100 simultaneously, thereby realizing the function of differential control of the two air outlet columns 100.

[0071] In some embodiments of the present application, the air conditioner 10 further comprises a throttling device 140. The throttling device 140 is upstream of the heat exchanger 120. The throttling device 140 is used to control the amount of working medium entering the heat exchanger 120. The throttling device 140 generally comprises a capillary, a mechanical expansion valve, an electronic expansion valve or an electromagnetic valve, and preferably the throttling device 140 is an electromagnetic valve.

[0072] In some embodiments of the present application, the air conditioner 10 further comprises a compressor 160, a condenser 150 connected with the throttling device 140, and a four-way valve 180 connected between the three-way valve 170 and the compressor 160. The compressor 160 comprises a liquid accumulator 190.

[0073] As shown, Figures 3-4 Further, in some optional embodiments of the present application, the two air outlet columns 100 are symmetrically arranged about a vertically extending reference plane extending front to back. The symmetrically arranged air outlet columns 100 make the appearance of the indoor unit of the vertical air conditioner stable and conform to the aesthetics of the Chinese people.

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

[0075] Two air outlet columns 100 are arranged at intervals to form an air guiding interval 200 between the two air outlet columns 100. When the two air outlet columns 100 blow air forward, the air in the air guiding interval 200 is driven to flow forward by the negative pressure, so that the air is mixed with the air blown by the two air outlet columns 100, and the air temperature is increased to prevent the air from being too hard and to produce a soft air effect.

[0076] In some optional embodiments of the present application, the air guiding interval 200 only includes an air inlet section and an air outlet section connected with 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 arrangement of the air guiding interval 200 is beneficial to the air at the rear side of the air guiding interval 200 and beneficial to the air in the air guiding interval 200 to flow forward.

[0077] Figure 3 is a schematic cross-sectional view of an air conditioner according to an embodiment of the present application, and Figures 4-6 The present application also provides an air conditioner 10, which includes a controller 300. The controller includes a memory 310 and a processor 320, and the memory 310 stores a control program which is executed by the processor 320 to implement the control method of the air conditioner according to any one of the above embodiments.

[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 above control method embodiments, and will not be repeated here.

[0079] The present application provides a plurality of exemplary embodiments, but many other variants or modifications conforming to the principles of the present application can be directly determined or deduced from the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variants or modifications.
