[0002] Currently, dual-column air conditioners consist of two parallel outlet columns, each of which can only simultaneously discharge heated air or non-heated air. Existing dual-column air conditioners offer a relatively simple air delivery mode, failing to meet the diverse needs of users. In particular, when the heated air from the left and right air columns converge, the air volume increases within the airflow intersection area. This results in increased wind speed and a sharper sensation of heat and cold for users within this area, leading to a poor user experience. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide an air conditioner and its control method that overcome the above problems or at least partially solve the above problems, aiming to solve the problem that the air supply mode of the existing air conditioner is relatively single, so as to achieve the purpose of improving the user experience.

[0041] 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 2-9 The present invention provides a control method for an air conditioner, including two side-by-side air outlet columns 100. The air conditioner has a soft air mode, in which one air outlet column 100 discharges heat exchange air, while the other air outlet column 100 discharges non-heat exchange air. The air outlet areas of the two air outlet columns 100 overlap, referred to as a soft air area 200.

[0042] like Figure 1 As shown, the control method of the air conditioner includes the following steps:

[0043] Step S11: Obtain the user location of the user.

[0044] Step S12 , executing the soft wind mode according to the user's position and the soft wind area 200 .

[0045] Specifically, each air outlet column 100 has an air outlet 110 at its front side. The non-heat exchange air can be indoor air or outdoor air.

[0046] In this embodiment, since the air conditioner has a soft wind mode; when the soft wind mode is running, the two air outlet columns 100 perform differentiated air supply, one air outlet column 100 discharges heat exchange air, and the other air outlet column 100 discharges non-heat exchange air, which can reduce the heat exchange capacity (cooling capacity or heating capacity) of the air conditioner. The above two types of wind are mixed together in the overlapping air outlet area of ​​the two air outlet columns 100 to form "soft" wind. In this overlapping air outlet area, the user will not have a strong sense of cold or heat, thereby improving the user's comfortable air supply experience. In addition, since the control method of the present invention executes the soft wind mode according to the user position and the soft wind area 200, it can meet the specific usage needs of different users. Therefore, the present invention can achieve diversified air supply, meet the diverse usage needs of users, and achieve the purpose of improving the user's usage experience.

[0047] In some optional embodiments of the present invention, the soft wind mode includes a soft wind direct blowing mode and a soft wind swinging mode.

[0048] Furthermore, in some optional embodiments of the present invention, the soft wind swing mode is: one of the air outlet columns 100 swings to discharge air, and the other air outlet column 100 is fixed to discharge air, and the two air outlet columns 100 perform the operation alternately.

[0049] Specifically, the fixed air outlet of the air outlet column 100 means that the air outlet direction of the air outlet column is fixed. When the air conditioner operates in the soft wind swing mode, the two air outlet columns 100 do not swing and discharge air at the same time, that is, the two air outlet columns 100 swing and discharge air alternately.

[0050] In some other optional embodiments of the present invention, the soft wind swing mode is: the two air outlet columns 100 swing to the left or to the right at the same time to discharge air.

[0051] Specifically, the two air outlet columns 100 swing to discharge air simultaneously, and can swing to the left or to the right at the same time to discharge air.

[0052] In some embodiments of the present invention, the soft wind direct blowing mode is: the air outlet directions of the two air outlet columns 100 are fixed and blow air toward the user or near the user at the same time.

[0053] like Figure 2 As shown, the execution of the soft wind mode includes the following steps:

[0054] Step S21 : sending a first inquiry message to the user as to whether to start the soft wind direct blowing mode or the soft wind swinging mode.

[0055] Step S22: In response to the first feedback instruction sent by the user, executing the operation mode corresponding to the first feedback instruction.

[0056] Specifically, the "execution of soft wind mode" in step S12 includes the following steps: first, a first inquiry message is sent to the user to determine whether the user wishes to activate the soft wind direct blowing mode or the soft wind swinging mode; then, upon receiving a first feedback instruction from the user, the operating mode corresponding to the first feedback instruction is executed according to the first feedback instruction. For example, if the first feedback instruction is to activate the soft wind direct blowing mode, the air conditioner will activate the soft wind direct blowing mode; if the first feedback instruction is to activate the soft wind swinging mode, the air conditioner will activate the soft wind swinging mode. In other words, after the air conditioner sends the first inquiry message to the user, if the user makes a selection based on the first inquiry message, the air conditioner will activate the corresponding soft wind mode based on the user's selection.

[0057] In this embodiment, when the soft wind mode is executed, a first inquiry message is first sent to the user, and then the soft wind mode corresponding to the first feedback instruction sent by the user is executed, which can further meet the user's personalized usage needs, thereby further improving the user's usage experience.

[0058] like Figure 2 As shown, further, in some optional embodiments of the present invention, the control method further includes: step S23, in response to the user not sending the first feedback instruction, executing the soft wind direct blowing mode.

[0059] Specifically, after step S21, if the user does not issue the first feedback instruction, both air outlet columns 100 of the air conditioner will execute the soft air direct blowing mode. In other words, after the air conditioner issues the first inquiry message to the user, if the user does not make a selection based on the first inquiry message, both air outlet columns 100 of the air conditioner will default to the soft air direct blowing mode.

[0060] Furthermore, in some optional embodiments of the present invention, the control method further includes: in response to the user position being within the soft wind area 200, sending a first inquiry message to the user as to whether to turn on the soft wind direct blowing mode or the soft wind swinging mode.

[0061] like Figure 3 As shown, in some embodiments of the present invention, executing the soft wind mode according to the user position and the soft wind area 200 includes the following steps:

[0062] Step S31 , determining whether the user is in the soft wind area 200 .

[0063] Step S32: If not, output a prompt message to remind the user that the user is not in the soft wind area 200; and send a second inquiry message to the user whether to turn on the soft wind mode.

[0064] Step S33: respond to the second feedback instruction sent by the user and execute the operation mode corresponding to the second feedback instruction.

[0065] Preferably, in response to the second feedback instruction to turn on the soft wind mode, the air conditioner executes the soft wind mode.

[0066] In this embodiment, a determination is first made as to whether the user is within soft wind zone 200. Based on the determination, a corresponding control method is then executed, thereby providing the user with a more user-friendly experience. Specifically, if the user is not within soft wind zone 200, and the soft wind mode is not enabled, a prompt message is displayed to the user, asking whether to enable the soft wind mode. If the user chooses to remain in the soft wind mode, the air conditioner is controlled to operate in the soft wind mode. If the user chooses not to enable the soft wind mode, the air conditioner is controlled to operate in another operating mode.

[0067] Furthermore, in some optional embodiments of the present invention, after the step of outputting prompt information, the control method further includes: sending image information including the soft wind area 200 and the user position.

[0068] In some other optional embodiments of the present invention, at the same time as the step of outputting the prompt information, the control method further includes: sending image information including the soft wind area 200 and the user position.

[0069] Preferably, in response to the second feedback instruction of not turning on the soft wind mode, image information including the soft wind area 200 and the user's location is sent to the user. Specifically, if the user chooses not to turn on the soft wind mode, a picture of the indoor soft wind area 200 is pushed to the user's mobile phone, and the user's location is corrected.

[0070] In these embodiments, through the above settings, the user can move to the soft wind area 200 according to the image information, making the air conditioner more humane and intelligent, and further improving the user's comfort.

[0071] In some optional embodiments of the present invention, the method for controlling an air conditioner further includes: obtaining a user location of a user in response to a request to start the soft wind mode.

[0072] Specifically, when a request for starting the soft wind mode is received from the user, the user's user location is obtained. In some alternative embodiments of the present invention, the user's user location is obtained in response to the air conditioner being started.

[0073] like Figure 4 As shown, in some preferred embodiments of the present invention, the control method of the air conditioner includes the following steps:

[0074] Step S1: In response to a request to start the soft wind mode, obtain the user location of the user.

[0075] Step S2: determining whether the user is within the soft wind area 200.

[0076] Step S3: If the user is not in the soft wind area 200, a prompt message is output to remind the user that the user is not in the soft wind area 200; and a second inquiry message is sent to the user to ask whether to turn on the soft wind mode.

[0077] Step S4: in response to the user sending a second feedback instruction to turn on the soft wind mode, the soft wind mode is turned on.

[0078] Step S5: in response to the second feedback instruction sent by the user to disable the soft wind mode, the soft wind mode is disabled, and image information including the soft wind area 200 and the user position is sent.

[0079] Step S6: If the user is in the soft wind area 200, a first inquiry message is sent to the user to turn on the soft wind direct blowing mode or the soft wind swinging mode.

[0080] Step S7: In response to the first feedback instruction sent by the user, executing the operation mode corresponding to the first feedback instruction.

[0081] Step S8: In response to the user not sending the first feedback instruction, executing the soft wind direct blowing mode.

[0082] In some embodiments of the present invention, obtaining the user location of the user includes the following steps: obtaining the user location through a radar sensor.

[0083] Specifically, the air conditioner includes a radar sensor, which is installed on the front side of a vertical air conditioner indoor unit.

[0084] In some other optional embodiments of the present invention, obtaining the user location of the user includes the following steps: obtaining the user location through an infrared device, a camera and / or a microphone.

[0085] In some other optional embodiments of the present invention, the obtaining of the user's user location includes the following steps: obtaining the user location by communicating with a body-worn device.

[0086] like Figure 5 As shown, in some optional embodiments of the present invention, a heat exchanger 120 is provided in each of the air outlet columns 100 .

[0087] The air conditioner further includes a flow control device configured to control the two heat exchangers 120 to operate simultaneously or to control only one of the heat exchangers 120 to operate.

[0088] In this embodiment, since each air outlet column 100 contains a heat exchanger 120, the two heat exchangers 120 are independent and can operate simultaneously or simultaneously, or only one can operate while the other does not. Therefore, when only one of the two heat exchangers 120 is operating while the other does not, one air outlet column 100 discharges heated air while the other discharges non-heated air or no air, thereby achieving differentiated air supply between the two air outlet columns 100. Therefore, the present invention can achieve diversified air supply, meeting the diverse usage needs of users.

[0089] In some embodiments of the present invention, each of the air outlets 110 is provided with an air guide device 111 , wherein the air guide device 111 includes at least one air guide plate for guiding air laterally. The air guide plate extends in a vertical direction.

[0090] For example, the air guide device 111 includes one air guide plate, two air guide plates, three air guide plates, or four air guide plates.

[0091] Furthermore, each of the air guide plates is connected to a drive motor to drive the movement of each air guide plate.

[0092] Preferably, the air guide device 111 includes two air guide plates. The air conditioner has a total of four air guide plates, and the four air guide plates are individually controlled by the drive motor.

[0093] like Figure 7 As shown, the soft wind area 200 is located in the right front of the air conditioner, which is the right soft wind area; at this time, the air outlet angle of the air conditioner is the maximum angle of the right soft wind, and the air guide plates of the two air outlet columns of the air conditioner are swung to the rightmost position, and the maximum range of the intersection of the two air outlet columns is the rightmost swing angle.

[0094] like Figure 8 As shown, the soft wind area 200 is located in the left front of the air conditioner, which is the left soft wind area; at this time, when the air outlet angle of the air conditioner is the maximum angle of the left soft wind, the air guide plates of the two air outlet columns are swung to the leftmost position, and the maximum range of the intersection of the two air outlet columns is the leftmost swing angle.

[0095] like Figure 9 As shown, when the air guide plates of the two air outlet columns of the air conditioner are swung inward to the maximum angle, that is, the air guide plate of the left air outlet column is swung to the rightmost air outlet angle, and the air guide plate of the right air outlet column is swung to the leftmost air outlet angle, the area of ​​the soft wind region 200 is the largest.

[0096] Furthermore, a fan 130 is further provided in each air outlet column 100. By adjusting the rotation speed of the fan 130, the air outlet speed of the air outlet column 100 can be adjusted.

[0097] In some optional embodiments of the present invention, the air outlets 110 are all vertical bar-shaped. The air outlet of the vertical bar-shaped air outlet 110 can avoid indoor temperature stratification, thereby making the indoor temperature uniform in the upper and lower directions and facilitating wide-area air supply.

[0098] In some optional embodiments of the present invention, two heat exchangers 120 are arranged in parallel. The flow 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 connected to the two heat exchangers 120 respectively. By controlling the on-off of the second opening and the third opening of the three-way valve, the on-off of the working medium 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, 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 dual air outlet columns 100.

[0099] 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 working fluid 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. Preferably, the throttling device is a solenoid valve.

[0100] In some embodiments of the present invention, the air conditioner further comprises a compressor, a condenser and a four-way valve connected in series between the three-way valve and the compressor, and the throttling device is connected to the condenser. The compressor comprises a liquid accumulator.

[0101] like Figure 5 As shown, further, in some optional embodiments of the invention, the two air outlet columns 100 are symmetrically arranged about a vertical reference plane extending forward and backward. The symmetrical arrangement of the air outlet columns 100 makes the vertical air conditioner indoor unit look stable and in line with the aesthetic taste of Chinese people.

[0102] The two air outlets 110 of the air conditioner are symmetrically arranged with respect to a vertical reference plane extending front to back.

[0103] like Figure 5 As shown, the two air outlet columns 100 are spaced apart to form an air induction gap 300 between the two air outlet columns 100. When the two air outlet columns 100 discharge air forward, the air in the air induction gap 300 is driven forward by negative pressure, so that this air is mixed with the air blown out by the two air outlet columns 100. During cooling, the air outlet temperature is increased, and the air is not too "hard", producing a "soft" air effect.

[0104] In some alternative embodiments of the present invention, the air inlet compartment 300 comprises only an interconnected air inlet section and an air outlet section. The width of the air outlet section gradually increases along the airflow direction. The width of the air inlet section gradually decreases along the airflow direction. This configuration of the air inlet compartment 300 facilitates the entry of air from the rear side of the air inlet compartment 300 and also facilitates the forward flow of air within the air inlet compartment 300.

[0105] Figure 5 is 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 6-9 The present invention further provides an air conditioner, comprising a control device. The control device comprises a memory and a processor. The memory stores a control program. When the control program is executed by the processor, it is used to implement the air conditioner control method described in any of the above embodiments.

[0106] 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 here.

[0107] The present invention has a plurality of exemplary embodiments, but, without departing from the spirit and scope of the present invention, many other variations or modifications that are consistent with the principles of the present invention can be directly determined or derived from the content disclosed in the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
