[0051] Figure 1 is a schematic flow chart of a method for controlling an air conditioner according to an embodiment of the present invention, and Figure 2-7 The present invention provides a control method for an air conditioner. The air conditioner includes two side-by-side air outlet columns 100. An air outlet 110 is provided on the front side of each air outlet column 100. The two air outlet columns 100 are respectively a first air outlet column and a second air outlet column.

[0052] The control method of the air conditioner comprises the following steps:

[0053] Step S11, obtaining the user position of the user, and obtaining the real-time air outlet intersection area 200 and the preset maximum air outlet intersection area of ​​the two air outlet columns 100.

[0054] Step S12, controlling the air outlet speeds of the two air outlet columns 100 according to the user position, the real-time air outlet intersection area 200 and the preset maximum air outlet intersection area.

[0055] Specifically, the air conditioner includes a vertical air conditioner indoor unit, and the vertical air conditioner indoor unit includes two air outlet columns 100 .

[0056] In this embodiment, since the air outlet speeds of the two air outlet columns 100 are controlled according to the user position, the real-time air outlet intersection area 200 and the preset maximum air outlet intersection area, the air volume in the real-time air outlet intersection area 200 can be adjusted, and the air volume in the real-time air outlet intersection area 200 can be reduced or increased. In particular, when the real-time air outlet intersection area 200 covers the user position, the air outlet speeds of the two air outlet columns or one air outlet column are reduced to reduce the air volume in the real-time air outlet intersection area 200, thereby maintaining the actual wind speed at the user position unchanged or changing very little, thereby effectively avoiding the influence of the air outlet intersection area on the user's experience, and achieving the purpose of improving the user's experience. In addition, the control method of the present invention has the beneficial effect that the control program is simple and easy to execute.

[0057] like Figure 2As shown, in some embodiments of the present invention, the control of the air outlet speeds of the two air outlet columns according to the user position, the real-time air outlet intersection area 200 and the preset maximum air outlet intersection area includes the following steps:

[0058] Step S21, in response to at least one of the user positions being located within the preset maximum airflow intersection area, a base point is acquired according to at least one of the user positions located within the preset maximum airflow intersection area.

[0059] Step S22, when the real-time air outlet intersection area 200 starts to cover the base point, reduce the air outlet speed.

[0060] Specifically, when there is at least one user position within the preset maximum wind outlet intersection area, a base point is obtained according to at least one user position within the preset maximum wind outlet intersection area, and when the real-time wind outlet intersection area 200 begins to cover the base point, the wind outlet speed is reduced.

[0061] In this embodiment, when the real-time air outlet intersection area 200 covers the base point, the air outlet speed of two air outlet columns or one air outlet column is reduced to reduce the air outlet volume in the real-time air outlet intersection area 200, so that the actual wind speed at the base point remains unchanged or changes very little, thereby effectively avoiding the influence of the air outlet intersection area on the user experience and achieving the purpose of improving the user experience.

[0062] In some optional embodiments of the present invention, when the real-time wind outlet intersection area 200 covers the base point, the wind speed at the base point is recorded as the first actual wind speed; when the real-time wind outlet intersection area 200 does not cover the base point, the wind speed at the base point is recorded as the second actual wind speed; the difference between the first actual wind speed and the second actual wind speed is less than a set value.

[0063] In some optional embodiments of the present invention, the lowering of the air outlet speed comprises the following steps: obtaining the air outlet speed before the real-time air outlet intersection area 200 begins to cover the base point to obtain a first air outlet speed; when the real-time air outlet intersection area 200 begins to cover the base point, executing a second air outlet speed, the second air outlet speed being equal to the product of the first air outlet speed and a preset coefficient, the preset coefficient being 40% to 80%. For example, the preset coefficient is 40%, 50%, 60%, 70% or 80%. Preferably, the preset coefficient is 60%.

[0064] In some optional embodiments of the present invention, obtaining a base point based on at least one user position located within the preset maximum wind outlet intersection area includes: determining a benchmark user position based on at least one user position located within the preset maximum wind outlet intersection area, and determining a base point based on the benchmark user position.

[0065] Furthermore, if Figure 6 As shown, in some embodiments of the present invention, determining the benchmark user position based on at least one of the user positions located in the preset maximum wind outlet intersection area includes: in response to a user position being located in the preset maximum wind outlet intersection area, determining a user position located in the wind outlet intersection area as the benchmark user position.

[0066] Specifically, when the preset maximum air outlet intersection area covers only one user position, the user position is used as the reference user position, and the base point is determined according to the reference user position.

[0067] like Figure 7 As shown, in other embodiments of the present invention, determining the reference user position based on at least one of the user positions located in the preset maximum air outlet intersection area includes: in response to at least two of the user positions being located in the preset maximum air outlet intersection area, determining the user position among the user positions located in the preset maximum air outlet intersection area that is farthest from the air conditioner in the front-to-back direction as the reference user position.

[0068] In this embodiment, since the intersection point at the rearmost side of the real-time air outlet intersection area 200 follows the increase of the inward air outlet angle of the two air outlet columns when the two air outlet columns discharge air inward, and changes from far to near, the real-time air outlet intersection area 200 also gradually becomes larger. That is to say, the user position farthest from the air conditioner in the front-to-back direction among the user positions located in the preset maximum air outlet intersection area is first covered by the real-time air outlet intersection area 200. Therefore, when the preset maximum air outlet intersection area covers at least two user positions, the user position farthest from the air conditioner in the front-to-back direction among the user positions located in the preset maximum air outlet intersection area is taken as the reference user position, and the base point is determined according to the reference user position. In this way, when the real-time air outlet intersection area 200 begins to cover the farthest user position, the air outlet speed of the air outlet column begins to be reduced, thereby starting to reduce the air volume of the real-time air outlet intersection area 200, which is more conducive to avoiding adverse effects on all user positions and can simultaneously improve the user experience of multiple users.

[0069] like Figure 6 and Figure 7 As shown, further, in some embodiments of the present invention, obtaining a base point according to the benchmark user position includes: taking the benchmark user position as a base point.

[0070] In some alternative embodiments of the present invention, acquiring a base point according to the reference user position includes: taking a preset distance in front of the reference user position as a base point.

[0071] Specifically, the preset distance in front of the reference user position refers to 0.01 to 0.05 m in front of the reference user position. For example, the preset distance is 0.05 m, 0.04 m, 0.03 mm, 0.02 mm, or 0.01 mm.

[0072] In some other embodiments of the present invention, the obtaining of the base point based on at least one user position located within the preset maximum wind outlet intersection area includes: obtaining the base point based on multiple user positions located within the preset maximum wind outlet intersection area, and the base point can be located at the center of each of the above-mentioned user positions.

[0073] In other embodiments of the present invention, the control method further includes: when the positions of each user are not located within the preset maximum air outlet intersection area, the inward extreme air outlet direction of the two air outlet columns 100 is not changed, and the preset maximum air outlet intersection area is kept unchanged.

[0074] like Figure 3 As shown, in some embodiments of the present invention, the control method of the air conditioner further includes the following steps:

[0075] Step S31, obtaining the indoor ambient temperature.

[0076] Step S32: in response to the difference between the indoor environment temperature and the target temperature being less than a preset value, obtaining the user location of the user.

[0077] Specifically, the preset value is 1 to 3° C. For example, the preset value is 1° C., 2° C. or 3° C.

[0078] In this embodiment, when the difference between the indoor ambient temperature and the target temperature is less than the preset value, it means that the indoor temperature will reach the target temperature, and the step of obtaining the user's user position is performed. When the difference between the indoor ambient temperature and the target temperature is not less than the preset value, it means that the indoor temperature is far from reaching the target temperature, and it is necessary to preferably quickly adjust the overall indoor temperature. At this time, even if the preset maximum air outlet intersection area covers the user's position, it will not have a significant impact on the user's position.

[0079] 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 air laterally.

[0080] 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.

[0081] Furthermore, each of the air guide plates is connected to a driving motor to drive the movement of each air guide plate.

[0082] Preferably, the air guide device 111 includes two air guide plates. The air conditioner has four air guide plates in total, and the four air guide plates are individually controlled by the driving motor.

[0083] Furthermore, a fan 130 is also provided in each air outlet column 100. The air outlet speed of the air outlet column can be adjusted by adjusting the rotation speed of the fan 130. The rotation speed of the fan 130 is positively correlated with the air outlet speed of the air outlet column. The greater the rotation speed of the fan 130, the greater the air outlet speed of the air outlet column, and the smaller the rotation speed of the fan 130, the smaller the air outlet speed of the air outlet column.

[0084] In some preferred embodiments of the present invention, while reducing the air outlet speed, the control also includes: reducing the swing speed.

[0085] Specifically, in step S22, when the real-time air outlet intersection area 200 begins to cover the base point, the air outlet speed of the air conditioner is reduced, and the swing speed of the two air outlet columns is reduced to prevent the air outlet speed from not being reduced due to the swing speed being too fast. In other words, when the real-time air outlet intersection area 200 begins to cover the base point, the rotation speed of the fan 130 is reduced, and the rotation speed of the air guide plates of the two air outlet columns is reduced to prevent the rotation speed of the air guide plates from being too fast, resulting in the rotation speed of the fan 130 not being reduced.

[0086] In some preferred embodiments of the present invention, the control method of the air conditioner comprises the following steps:

[0087] Step S41, when the air conditioner is started and the two air outlet columns are turned on in the swing mode, the user's user position is obtained through the radar sensor, and the real-time air outlet intersection area 200 and the preset maximum air outlet intersection area of ​​the two air outlet columns 100 are obtained.

[0088] Step S42, in response to at least two of the user positions being located within the preset maximum air outlet intersection area, determining the user position farthest from the air conditioner in the front-to-back direction among the user positions within the preset maximum air outlet intersection area as a base point.

[0089] Step S43, when the real-time air outlet intersection area 200 begins to cover the base point, the fan speeds of the two air outlet columns are reduced by 40% to maintain the wind speed in the real-time air outlet intersection area 200 stable; at the same time, the rotation speed of the drive motor is controlled to reduce the rotation speed of the air guide plate to prevent the air guide plate from rotating too fast and causing the fan speed to not be reduced before the air guide plate has swung over.

[0090] In some embodiments of the present invention, a heat exchanger 120 is disposed in each of the air outlet columns 100. The air conditioner further comprises 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.

[0091] 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.

[0092] Furthermore, in some embodiments of the present invention, the control method also includes: acquiring the indoor ambient temperature; controlling the operating mode of the two air outlet columns according to the indoor ambient temperature and the target temperature; the operating mode includes an air supply mode and a heat exchange mode.

[0093] The air supply mode of the air outlet column means that the fan in the air outlet column is working, and the heat exchanger is not working. The heat exchange mode of the air outlet column means that both the fan and the heat exchanger in the air outlet column are working.

[0094] During the cooling or heating operation of the air conditioner, when the indoor ambient temperature meets the preset conditions, one of the two heat exchangers 120 is controlled to work and the other is not to work, and the single heat exchange air mode is operated, so that one of the air outlet columns 100 discharges heat exchange air, and the other heat exchanger 120 does not discharge air or discharges non-heat exchange air (non-heat exchange air includes indoor air or fresh air). Thus, the heat exchange capacity (cooling capacity or heating capacity) of the air conditioner can be reduced, thereby avoiding the air conditioner from shutting down due to reaching the temperature, and can also improve the user's comfortable air supply experience. Therefore, the present invention can realize diversified air supply and meet the diversified usage needs of users.

[0095] In some embodiments of the present invention, the step of obtaining the user location of the user comprises the following steps: obtaining the user location through a radar sensor.

[0096] Specifically, the air conditioner includes a radar sensor. The radar sensor is installed on the front side of the vertical air conditioner indoor unit.

[0097] In some other optional embodiments of the present invention, obtaining the user position of the user includes the following steps: obtaining the user position through an infrared device, a camera and / or a microphone.

[0098] In some other optional embodiments of the present invention, the method of obtaining the user's location includes the following steps: obtaining the user's location by communicating with a human-worn device.

[0099] like Figure 4-7 As shown, in some optional embodiments of the present invention, the air outlets are all vertical bar-shaped. The air outlet of the vertical bar-shaped air outlet can avoid indoor temperature stratification, thereby making the indoor temperature uniform in the upper and lower directions and facilitating wide-area air supply.

[0100] In some optional embodiments of the present invention, two heat exchangers 120 are arranged in parallel. The flow path control device includes a three-way valve. The three-way valve includes three openings, namely a first opening, a second opening and a third opening. The first opening is connected to the four-way valve, 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, the on-off of the working fluid flow path in each heat exchanger 120 is controlled, and the execution of the action is stable and reliable. In other words, by controlling the opening of the three-way valve, 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.

[0101] In some embodiments of the present invention, the air conditioner further includes a throttling device. The throttling device is located upstream of the heat exchanger 120. The throttling device is used to control the amount of the working medium entering the heat exchanger 120. The throttling device generally includes a capillary tube, a mechanical expansion valve, an electronic expansion valve or a solenoid valve, etc. Preferably, the throttling device is a solenoid valve.

[0102] In some embodiments of the present invention, the air conditioner further comprises a compressor, a condenser and a four-way valve between the three-way valve and the compressor connected in series, and the throttling device is connected to the condenser. The compressor comprises a liquid storage device.

[0103] Furthermore, 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.

[0104] The two air outlets of the air conditioner are symmetrically arranged with respect to a vertical reference plane extending front to back.

[0105] like Figure 4 As shown, the two air outlet columns 100 are arranged at intervals so that an air induction interval 300 is formed between the two air outlet columns 100. When the two air outlet columns 100 discharge air forward, the air in the air induction interval 300 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.

[0106] In some optional embodiments of the invention, the air inlet interval 300 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 300 is conducive to the air entering the rear side of the air inlet interval 300 and is also conducive to the air in the air inlet interval 300 flowing forward.

[0107] Figure 4is a schematic cross-sectional view of a vertical indoor unit of an air conditioner according to an embodiment of the present invention, with reference to Figure 5-7 The present invention also provides an air conditioner, the air conditioner includes a control device. The control device includes a memory and a processor, the memory stores a control program, and the control program is used to implement the control method of the air conditioner as described in any of the above embodiments when executed by the processor.

[0108] It should be noted that the specific structure of the air conditioner includes the structure of the air conditioner in any one of the embodiments of the above control method, and will not be repeated.

[0109] 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.
