[0051] Figure 1 is a schematic flow chart of the control method of the air conditioner according to an embodiment of the present application, and in combination with Figures 2-7 The present application provides a control method of an air conditioner, the air conditioner comprising two air outlet columns 100 arranged side by side, and an air outlet 110 is formed 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] In step S11, the user position of a user is obtained, 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.

[0054] In step S12, the air outlet speed of the two air outlet columns 100 is controlled 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 comprises a vertical air conditioner indoor unit, and the vertical air conditioner indoor unit comprises two air outlet columns 100.

[0056] In the embodiment, since the air outlet speed of the two air outlet columns 100 is controlled according to the user position, the real-time air outlet intersection area 200 and the preset maximum air outlet intersection area, the air outlet volume in the real-time air outlet intersection area 200 can be adjusted, that is, the air outlet volume in the real-time air outlet intersection area 200 can be reduced or increased. Especially, when the real-time air outlet intersection area 200 covers the user position, the air outlet speed of the 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 user position is maintained unchanged or changes 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. In addition, the control method of the present application has the beneficial effects of simple control program and easy execution.

[0057] As Figure 2As shown, in some embodiments of the present application, the controlling the air outlet speed 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 comprises the following steps:

[0058] In step S21, a base point is obtained according to at least one user position located in the preset maximum air outlet intersection area in response to at least one user position located in the preset maximum air outlet intersection area.

[0059] In step S22, the air outlet speed is reduced when the real-time air outlet intersection area 200 starts to cover the base point.

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

[0061] In this embodiment, when the real-time air outlet intersection area 200 covers the base point, the air outlet speed of the 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 air speed at the base point remains unchanged or changes 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 application, when the real-time air outlet intersection area 200 covers the base point, the air speed at the base point is referred to as a first actual air speed; when the real-time air outlet intersection area 200 does not cover the base point, the air speed at the base point is referred to as a second actual air speed; the difference between the first actual air speed and the second actual air speed is less than a set value.

[0063] In some optional embodiments of the present application, the reducing the air outlet speed comprises the following steps: obtaining the air outlet speed before the real-time air outlet intersection area 200 starts to cover the base point to obtain a first air outlet speed; and executing a second air outlet speed when the real-time air outlet intersection area 200 starts to cover the base point, 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 application, the obtaining the base point according to at least one user position located in the preset maximum air outlet intersection area comprises: determining a reference user position according to at least one user position located in the preset maximum air outlet intersection area, and determining the base point according to the reference user position.

[0065] Further, as shown in Figure 6 In some embodiments of the present application, the determining the reference user position according to at least one of the user positions located in the preset maximum air outflow intersection region comprises: in response to one of the user positions being located in the preset maximum air outflow intersection region, determining the one of the user positions located in the air outflow intersection region as the reference user position.

[0066] Specifically, when the preset maximum air outflow intersection region covers only one user position, the user position is taken as the reference user position, and the reference user position is used to determine the base point.

[0067] As shown in Figure 7 In some embodiments of the present application, the determining the reference user position according to at least one of the user positions located in the preset maximum air outflow intersection region comprises: in response to at least two of the user positions being located in the preset maximum air outflow intersection region, determining the one of the user positions located in the preset maximum air outflow intersection region and farthest from the air conditioner in the front-rear direction as the reference user position.

[0068] In the present embodiment, since the intersection points at the last side of the real-time air outflow intersection region 200 follow the increase of the inward air outflow angles of the two air outflow columns and change from far to near when the two air outflow columns outflow air inward, the real-time air outflow intersection region 200 also gradually increases. That is, the user position farthest from the air conditioner in the front-rear direction among the user positions located in the preset maximum air outflow intersection region is covered by the real-time air outflow intersection region 200 first. Therefore, when the preset maximum air outflow intersection region covers at least two user positions, the user position farthest from the air conditioner in the front-rear direction among the user positions located in the preset maximum air outflow intersection region is taken as the reference user position, and the reference user position is used to determine the base point. In this way, when the real-time air outflow intersection region 200 starts to cover the above-mentioned farthest user position, the air outflow speed of the air outflow column is started to be reduced, so that the air volume of the real-time air outflow intersection region 200 is started to be reduced, which is more conducive to avoiding adverse effects on all user positions and improving the use experience of multiple users.

[0069] As shown in Figure 6 and Figure 7 Further, in some embodiments of the present application, the obtaining the base point according to the reference user position comprises: taking the reference user position as the base point.

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

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

[0072] In some embodiments of the present application, the reference user position is located in the preset maximum air outlet intersection region.

[0073] In some embodiments of the present application, the control method further comprises the following steps:

[0074] As shown in FIG. 1, in some embodiments of the present application, the control method of the air conditioner further comprises the following steps: Figure 3

[0075] Step S31: obtaining the indoor environment temperature.

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

[0077] Specifically, the preset value is 1-3 ℃. For example, the preset value is 1 ℃, 2 ℃ or 3 ℃.

[0078] In this embodiment, when the difference between the indoor environment temperature and the target temperature is less than the preset value, it indicates that the indoor temperature will reach the target temperature, and the step of obtaining the user position of the user is performed. When the difference between the indoor environment temperature and the target temperature is not less than the preset value, it indicates that the indoor temperature is far from the target temperature, and the overall indoor temperature needs to be quickly adjusted. In this case, even if the preset maximum air outlet intersection region covers the user position, it will not have a great impact on the user position.

[0079] In some embodiments of the present application, each air outlet 110 is provided with a wind guide device 111; the wind guide device 111 comprises at least one wind guide plate for transverse air guiding.

[0080] For example, the wind guide device 111 comprises one wind guide plate or two wind guide plates or three wind guide plates or four wind guide plates.

[0081] Further, each wind guide plate is connected to a driving motor to drive the movement of each wind guide plate.

[0082] ​Preferably, the air guide device 111 comprises two air guide plates. The air conditioner has four air guide plates, which are individually controlled by driving motors.

[0083] Further, each air outlet column 100 is provided with a fan 130. By adjusting the rotating speed of the fan 130, the air outlet speed of the air outlet column can be adjusted. The rotating speed of the fan 130 is positively correlated with the air outlet speed of the air outlet column. The greater the rotating speed of the fan 130, the greater the air outlet speed of the air outlet column. The smaller the rotating speed of the fan 130, the smaller the air outlet speed of the air outlet column.

[0084] In some preferred embodiments of the present application, while the air outlet speed is reduced, the control further comprises reducing the swing speed.

[0085] Specifically, in step S22, when the real-time air outlet intersection area 200 starts 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, so as to prevent the swing speed from being too fast to cause the air outlet speed not to be reduced. That is, when the real-time air outlet intersection area 200 starts to cover the base point, the rotating speed of the fan 130 is reduced, and the rotating speed of the air guide plates of the two air outlet columns is reduced, so as to prevent the rotating speed of the air guide plates from being too fast to cause the rotating speed of the fan 130 not to be reduced.

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

[0087] In step S41, when the air conditioner is started and the two air outlet columns are in the swing mode, the user positions of the users are obtained by 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] In step S42, in response to at least two user positions being located in the preset maximum air outlet intersection area, the user position farthest from the air conditioner in the front-back direction among the user positions located in the preset maximum air outlet intersection area is determined as a base point.

[0089] In step S43, when the real-time air outlet intersection area 200 starts to cover the base point, the rotating speed of the fan of the two air outlet columns is reduced by 40%, so as to maintain the stability of the air speed in the real-time air outlet intersection area 200; at the same time, the rotating speed of the driving motor is controlled, so as to reduce the rotating speed of the air guide plate, prevent the rotating speed of the air guide plate from being too fast to cause the rotating speed of the fan not to be reduced, and the air guide plate has been swung.

[0090] In some embodiments of the present application, each air outlet column 100 is provided with a heat exchanger 120. The air conditioner further comprises a flow path 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 simultaneously, can not work simultaneously, or only one of them works while the other one does not work. Therefore, when only one of the two heat exchangers 120 works while the other one does not work, one air outlet column 100 outputs heat-exchanged air, and the other air outlet column 100 outputs non-heat-exchanged air or no air, so that the differential air supply of the two air outlet columns 100 can be realized.

[0092] Further, in some embodiments of the present application, the control method further comprises: obtaining the indoor environment temperature; and controlling the operation mode of the two air outlet columns according to the indoor environment temperature and the target temperature; the operation mode includes the air supply mode and the heat exchange mode.

[0093] The air outlet column running in the air supply mode means that the fan in the air outlet column works, and the heat exchanger does not work. The air outlet column running in the heat exchange mode means that both the fan and the heat exchanger in the air outlet column work.

[0094] During the refrigeration or heating operation of the air conditioner, when the indoor environment temperature meets the preset condition, one of the two heat exchangers 120 works while the other one does not work, and the single-heat-exchanged air supply mode is run, so that one of the air outlet columns 100 outputs heat-exchanged air, and the other heat exchanger 120 does not output air or outputs non-heat-exchanged air (the non-heat-exchanged air includes indoor air or fresh air). Therefore, the heat exchange capacity (refrigeration capacity or heating capacity) of the air conditioner can be reduced, so that the temperature-reached shutdown of the air conditioner can be avoided, and the comfortable air supply experience of the user can be improved. Therefore, the present application can realize diversified air supply and meet the diversified use requirements of the user.

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

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

[0097] In some optional embodiments of the present application, the obtaining of the user position of the user comprises the following steps: obtaining the user position through an infrared device, a camera and / or a sound pickup device.

[0098] In some optional embodiments of the present application, the obtaining of the user position of the user comprises the following steps: obtaining the user position by communicating with a human body wearing device.

[0099] As shown in FIG. 1, Figures 4-7 In some optional embodiments of the present application, the air outlets are vertical strip-shaped, and the air outlet of the vertical strip-shaped air outlet can avoid the stratification of the indoor temperature, so that the indoor temperature is uniform in the up-down direction, and wide-area air supply can be easily realized.

[0100] In some alternative embodiments of the present application, two heat exchangers 120 are arranged in parallel. The flow path control device comprises a three-way valve. The three-way valve comprises three openings, 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 connected to the two heat exchangers 120 respectively. By controlling the opening and closing of the second opening and the third opening of the three-way valve, the opening and closing of the flow path of the working medium in each heat exchanger 120 is controlled, and the action is stable and reliable. That is, by controlling the opening degree of the three-way valve, the refrigerant can flow to one air outlet column 100 or to two air outlet columns 100 at the same time, thereby realizing the function of controlling two air outlet columns 100 separately.

[0101] In some embodiments of the present application, the air conditioner further comprises a throttling device. The throttling device is upstream of the heat exchanger 120. The throttling device is used to control the amount of working medium entering the heat exchanger 120. The throttling device generally comprises a capillary, a mechanical expansion valve, an electronic expansion valve or an electromagnetic valve, and preferably the throttling device is an electromagnetic valve.

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

[0103] Further, in some alternative 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 upright air conditioner stable and conform to the aesthetics of the Chinese people.

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

[0105] As shown in Figure 4 The two air outlet columns 100 are arranged at intervals to form an air guiding interval 300 between the two air outlet columns 100. When the two air outlet columns 100 blow air forward, the air in the air guiding interval 300 is driven to flow forward by the negative pressure, so that the air is mixed with the air blown out by the two air outlet columns 100. In the case of refrigeration, the temperature of the air is improved, so that the air is not too "hard" and the effect of "soft" air is achieved.

[0106] In some alternative embodiments of the present application, the air guiding interval 300 only comprises 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 arrangement of the air guiding interval 300 is beneficial to the air at the rear side of the air guiding interval 300 entering and also beneficial to the air in the air guiding interval 300 flowing forward.

[0107] Figure 4is a schematic cross-sectional view of a stand-type indoor unit of an air conditioner according to an embodiment of the present application, and Figures 5-7 The present application also provides an air conditioner comprising a control device. The control device comprises a memory and a processor, and the memory stores a control program which, when executed by the processor, is used to implement the control method of the air conditioner according to any one of the above embodiments.

[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 above control method embodiments, which will not be repeated.
