[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following describes a method for controlling an air conditioner, a control device for an air conditioner, a computer-readable storage medium, and an air conditioner according to embodiments of the present invention with reference to the accompanying drawings.

[0036] Figure 1 FIG. 4 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention.

[0037] like Figure 1 As shown, the control method of the air conditioner according to the embodiment of the present invention may include the following steps:

[0038] S1, in the wind blowing mode, a first control distance is determined according to the user's body surface temperature and the indoor ambient temperature, and the air conditioner is controlled according to the actual distance between the user and the air conditioner and the first control distance to achieve wind blowing on people.

[0039] S2, and / or, in the wind avoidance mode, the air conditioner is controlled according to the actual distance between the user and the air conditioner and the second control distance to achieve wind avoidance, wherein the second control distance is a preset control distance.

[0040] Specifically, different air conditioners may include different functions. For example, in one air conditioner, it may only include the wind blowing mode, or it may only include the wind avoiding mode, or in one air conditioner, it may include both the wind blowing mode and the wind avoiding mode. That is to say, the user can freely choose whether to turn on the wind blowing mode or the wind avoiding mode according to the user's choice. In an air conditioner that only includes the wind blowing mode, when the user selects the wind blowing mode, for example, the user can make the selection through the air conditioner remote control, or through a mobile device connected to the air conditioner, such as an application on a mobile phone. After the user selects, that is, in the wind blowing mode, the air outlet of the air conditioner will change the wind sweeping angle according to the user's position, so as to blow the wind to the user's position.

[0041] When the wind blows on people, the user's body surface temperature and the indoor environment temperature can be obtained first. For example, the user's body surface temperature and the indoor environment temperature can be obtained through a temperature sensor. The user may remain motionless near the air conditioner, or may keep walking near the air conditioner. It is necessary to obtain the actual distance between the user and the air conditioner so as to control the distance that the air outlet of the air conditioner can reach according to the actual distance, so as to blow to the user. For example, the user's position and the position of the air conditioner can be determined by a position sensor. After obtaining the user's position and the position of the air conditioner, the actual distance between the user and the air conditioner can be determined. For example, a UWB (Ultra Wide Band) sensor can be installed on the user, such as on a sports bracelet or a mobile phone, so that the user's current position can be accurately obtained when the user moves. In addition, for children or people who like dolls, UWB sensors can also be installed on dolls, pillows, etc., so that when the user holds a doll or pillow to rest at night, the user's current position can also be obtained. Another UWB sensor is installed inside the indoor unit of the air conditioner, so that the position of the air conditioner can be obtained. The air conditioner receives the UWB signal from the user to obtain the actual distance. For example, the user's position is (X 1 , Y 1 ), the position of the air conditioner is (X 2 , Y 2 ), so that the distance between the user and the air conditioner can be determined to be

[0042] After determining the user's body surface temperature and the indoor environment temperature, the first control distance can be determined according to the user's body surface temperature and the indoor environment temperature, that is, the first control distance changes in real time, that is, the first control distance changes according to the change of the user's body surface temperature and the change of the indoor environment temperature. For example, the first control distance can be determined according to the sum of the user's body surface temperature and the indoor environment temperature, such as by a table lookup method, the values ​​of the sum of multiple user's body surface temperatures and the indoor environment temperature and the first control distance corresponding to the sum of multiple user's body surface temperatures and the indoor environment temperature can be stored in the table, and after determining the sum of a user's body surface temperature and the indoor environment temperature, the corresponding first control distance can be determined. When the sum of the user's body surface temperature and the indoor environment temperature is larger, it means that the current user's body surface temperature is higher or the indoor environment temperature is higher, and the first control distance can be determined to be farther, so that the air of the air conditioner can blow to a farther distance, so that the user can be blown directly by the wind at a farther position, and when the sum of the user's body surface temperature and the indoor environment temperature is smaller, it means that the current user's body surface temperature is lower or the indoor environment temperature is lower, and the first control distance can be determined to be closer, so that the air of the air conditioner can blow to a closer distance.

[0043] After determining the first control distance, since the user may be out or far away from the air conditioner, it is also necessary to control the air conditioner based on the relationship between the actual distance between the user and the air conditioner and the first control distance. For example, the sum of the actual distance and the first control distance can be calculated. When the sum of the actual distance and the first control distance is lower than a certain value, it means that the user is close to the air conditioner, and the air conditioner can be controlled, such as controlling the air guide angle and fan speed of the air conditioner to achieve wind blowing on people. For another example, the difference between the actual distance and the first control distance can be calculated, and when the difference is less than the preset difference, the air conditioner is controlled. For example, when the actual distance is 5 meters, the preset difference is 2 meters, and the first control distance is 6 meters, it can be determined that the difference is less than the preset difference, and the air conditioner can be controlled, such as controlling the air guide plate angle and fan speed of the air conditioner to achieve wind blowing on people. As the indoor ambient temperature and the user's body surface temperature decrease, the first control distance becomes 2 meters, and it can be determined that the difference is greater than the preset difference. At this time, the air conditioner is not controlled and the normal operation of the air conditioner is maintained. As the air-conditioned wind diffuses, it has become a relatively gentle wind speed when it blows to the user's body surface, which can meet the comfortable environment required by the human body. If the user still wants the wind to blow directly, he can continue to get closer to the air conditioner until the difference is less than the preset difference.

[0044] Alternatively, in an air conditioner that only includes a wind avoidance mode, when a user selects the wind avoidance mode, for example, the user can make the selection through the air conditioner remote control, or through a mobile device interconnected with the air conditioner, such as an application on a mobile phone. After the user selects, that is, in the wind avoidance mode, the air outlet of the air conditioner will change the wind sweeping angle according to the user's position to avoid blowing the wind to the user's position. Specifically, when the air conditioner is in the wind avoidance mode, the air conditioner can be controlled according to the actual distance between the user and the air conditioner and the second control distance, so as to achieve wind avoidance, so as to solve the problems of some people getting dizzy, having a headache, and feeling cold when being blown directly by the air conditioner in summer.

[0045] First, it is possible to determine whether the air conditioner needs to be controlled based on the size relationship between the actual distance between the user and the air conditioner and the second control distance. For example, when the actual distance is greater than the second control distance, since the relative distance between the user and the air conditioner is relatively far, as the air conditioning wind diffuses, it has become a gentle wind speed when it blows to the user's body surface, which can meet the comfortable environment required by the human body. Therefore, the air conditioner does not need to be adjusted, such as adjusting the speed of the indoor fan of the air conditioner, adjusting the angles of the air guide strips and the left and right air guide strips on the air conditioner, etc. It should be noted that the second control distance is a preset control distance, which can be determined according to the length or width of the room, for example, half of the length of the room can be used as the preset control distance. For example, if the length of the room is 8 meters, the preset control distance can be set to 4 meters.

[0046] For another example, the size between the actual distance and the second control distance is judged. When the actual distance is smaller than the second control distance, it indicates that the current user is relatively close to the air conditioner. The indoor air outlet angle can be adjusted, such as controlling the upper and lower air guide bars and the left and right air guide bars of the air conditioner to change the indoor air outlet angle, thereby avoiding the wind from blowing directly on the user and achieving the goal of avoiding the wind from blowing on people.

[0047] Alternatively, in an air conditioner that includes both a wind-avoiding-people mode and a wind-blowing-people mode, the user can freely select whether to turn on the wind-blowing-people mode or the wind-avoiding-people mode based on the user's choice. For example, when the user selects the wind-blowing-people mode as the current mode through the air conditioner remote control or the application of a mobile device, the air conditioner can be controlled according to the actual distance between the user and the air conditioner and the first control distance to achieve the wind blowing people. When the user selects the current mode as the wind-avoiding-people mode, the air conditioner can be controlled according to the actual distance between the user and the second control distance to achieve the wind-avoiding-people mode. The specific control method can be based on the method described in the above embodiment, which will not be repeated here.

[0048] Therefore, the method can determine the first control distance according to the user's body surface temperature and the indoor environment temperature in the wind blowing on people mode, and control the air conditioner according to the actual distance between the user and the air conditioner and the first control distance to achieve wind blowing on people, and / or, in the wind avoiding people mode, control the air conditioner according to the actual distance between the user and the air conditioner and the second control distance to achieve wind avoiding people, wherein the second control distance is a preset control distance, thereby making the control distance more flexible and effectively improving the user's comfort in the wind blowing on people and wind avoiding people modes.

[0049] The specific working process of the air conditioner control method of the present invention is described in detail below.

[0050] According to an embodiment of the present invention, determining the first control distance according to the user's body surface temperature and the indoor ambient temperature includes: obtaining the absolute temperature difference between the user's body surface temperature and the indoor ambient temperature; and determining the first control distance according to the absolute temperature difference.

[0051] Specifically, after obtaining the user's body surface temperature and the indoor ambient temperature, the absolute temperature difference between the user's body surface temperature and the indoor ambient temperature can be obtained through calculation. It can be understood that the absolute temperature difference is a positive value. When the user's body surface temperature is higher than the indoor ambient temperature, the absolute temperature difference between the user's body surface temperature and the indoor ambient temperature is the difference between the user's body surface temperature and the indoor ambient temperature. When the user's body surface temperature is lower than the indoor ambient temperature, the absolute temperature difference between the user's body surface temperature and the indoor ambient temperature is the opposite of the difference between the user's body surface temperature and the indoor ambient temperature.

[0052] After obtaining the absolute temperature difference, the first control distance can be determined according to the absolute temperature difference, that is, different temperature differences will result in different first control distances, so that the control distance is no longer a fixed value, allowing the air conditioner to be more flexibly controlled according to the distance when the wind blows on people.

[0053] According to an embodiment of the present invention, determining the first control distance according to the absolute temperature difference includes: determining the first control distance according to the absolute temperature difference and a preset relationship table; wherein the preset relationship table includes the first control distance corresponding to the absolute temperature difference; or the preset relationship table includes a first preset coefficient corresponding to the absolute temperature difference, and the first control distance is determined based on the first preset coefficient and the preset control distance. wherein the preset control distance can be determined according to actual conditions, and the absolute temperature difference is positively correlated with the first preset coefficient.

[0054] Specifically, when determining the first control distance according to the absolute temperature difference, it can be determined according to the absolute temperature difference and a preset relationship table. In the preset relationship table, one or more absolute temperature differences and the first control distances corresponding to the absolute temperature differences can be included, that is, the absolute temperature difference and the first control distance are in a one-to-one correspondence. After determining an absolute temperature difference, the corresponding first control distance can be determined.

[0055] In addition, when determining the first control distance, it can also be determined according to the absolute temperature difference and another preset relationship table. In the preset relationship table, a first preset coefficient corresponding to the absolute temperature difference may be included, that is, the absolute temperature difference and the first preset coefficient are in a one-to-one correspondence. After determining an absolute temperature difference, the corresponding first preset coefficient can be determined, and the absolute temperature difference is positively correlated with the first preset coefficient, that is, the larger the absolute temperature difference, the larger the first preset coefficient, and the smaller the absolute temperature difference, the smaller the first preset coefficient. After determining the first preset coefficient, the first control distance can be determined according to the first preset coefficient and the preset control distance. For example, the first control distance can be determined by multiplying the first preset coefficient by the preset control distance, as shown in Table 1.

[0056] Table 1

[0057] Absolute temperature difference (℃) First control distance (m) ΔT>5 100%-90%*K*d0 ΔT>4 90%-80%*K*d0 ΔT>3 80%-70%*K*d0 ΔT>2 70%-60%*K*d0 ΔT>1 60%-50%*K*d0

[0058] It can be seen from Table 1 that ΔT represents the absolute temperature difference between the user's body surface temperature and the indoor ambient temperature, 100%-90%*K, 90%-80%*K, 80%-70%*K, 70%-60%*K, 60%-50%*K represent the first preset coefficients corresponding to different absolute temperature differences, and d0 represents the preset control distance. The larger the absolute temperature difference, the larger the first preset coefficient, and the larger the corresponding first control distance when the preset distance remains constant; the smaller the absolute temperature difference, the smaller the first preset coefficient, and the smaller the corresponding first control distance when the preset distance remains constant. For example, when ΔT>5℃, the first control distance is 100%-90%*K*d0, when ΔT>4℃, the first control distance is 90%-80%*K*d0, when ΔT>3℃, the first control distance is 80%-70%*K*d0, when ΔT>2℃, the first control distance is 70%-60%*K*d0, and when ΔT>1℃, 60%-50%*K*d0.

[0059] For example, when the user's body surface temperature measured by the sensor is 28°C, and the indoor ambient temperature measured by the sensor is 22°C, it can be determined that the absolute temperature difference between the user's body surface temperature and the indoor ambient temperature is 6°C, that is, ΔT>5°C, and the first control distance is 100%-90%*K*d0. If 100%-90%*K is 1.1 and d0 is 5m, it can be determined that the current first control distance is 5.5m, which is 0.5m higher than the preset distance d0, that is, the user's current body surface temperature is high. If controlled according to the preset distance, the air conditioner's wind will not reach the user. Therefore, by increasing the preset distance, the air conditioner's wind can blow to the user, thereby bringing comfort to the user.

[0060] According to one embodiment of the present invention, the air conditioner is controlled according to the actual distance between the user and the air conditioner and the first control distance to achieve wind blowing on people, including: when the actual distance is less than the first control distance, adjusting the indoor air outlet angle, and adjusting the indoor fan speed according to the first control distance to achieve wind blowing on people.

[0061] Specifically, when the air conditioner is controlled according to the actual distance and the first control distance to achieve the wind blowing on people, the size relationship between the actual distance and the first control distance is first determined. When the actual distance is less than the first control distance, it means that the user is within the range that the air conditioner can blow when blowing, so that the indoor air outlet angle can be adjusted. For example, the upper and lower air guide strips of the air conditioner can be adjusted or the left and right air guide strips of the air conditioner can be controlled to change the air outlet angle, or the upper and lower air guide strips and the left and right air guide strips of the air conditioner can be controlled at the same time to change the air outlet angle. In addition, the fan speed of the indoor unit can be adjusted, and the indoor fan speed can be adjusted accordingly according to the first control distance. For example, according to the preset first control distance-indoor fan speed table, multiple first control distances and indoor fan speeds are stored in the table. After determining a first control distance, the corresponding indoor fan speed can be determined.

[0062] Further, according to an embodiment of the present invention, the indoor fan speed is determined by:

[0063]

[0064] Where v is the speed of the indoor fan, k is the second preset coefficient, and d is the actual distance. In the wind blowing mode, d i is the first control distance.

[0065] Specifically, when determining the indoor fan speed, it can be determined by the above formula (1), that is, in the second preset coefficient k and the first control distance d i When the actual distance d between the user and the air conditioner is smaller (determined according to the absolute temperature difference between the user's body surface temperature and the indoor ambient temperature), it can be determined through calculation that the indoor fan speed is smaller; if the actual distance d between the user and the air conditioner is larger (not exceeding the first control distance), it can be determined through calculation that the indoor fan speed is larger. Therefore, when the user is closer to the air conditioner, a smaller wind speed can be used to cool or heat the user, thereby avoiding excessive wind speed and long-term direct exposure to strong wind, which affects the user's health. When the user is farther away from the air conditioner, the wind speed can be made higher, so that the user can feel the air blowing from the air conditioner at a long distance, giving the user a comfortable experience.

[0066] According to one embodiment of the present invention, the air conditioner is controlled according to the actual distance between the user and the air conditioner and the second control distance to achieve wind avoiding people, including: when the actual distance is less than the second control distance, adjusting the indoor air outlet angle, and adjusting the indoor fan speed according to the second control distance to achieve wind avoiding people.

[0067] Specifically, when the air conditioner is in the wind avoidance mode, the air conditioner can be controlled according to the actual distance and the second control distance, so as to achieve wind avoidance, so as to solve the problems that some people will feel dizzy, have a headache, feel cold, etc. when they are blown directly against the air conditioner in summer. First, it can be judged whether the air conditioner needs to be controlled according to the size relationship between the actual distance between the user and the air conditioner and the second control distance. That is, when the actual distance is greater than the second control distance, since the relative distance between the user and the air conditioner is far, as the air conditioning wind diffuses, it has become a gentle wind speed when it blows to the user's body surface, which can meet the comfortable environment required by the human body. Therefore, the air conditioner can be adjusted without adjusting the speed of the indoor fan of the air conditioner, adjusting the angle of the air guide strip and the left and right air guide strips on the air conditioner, etc. It should be noted that the second control distance is a preset control distance, which can be determined according to the length or width of the room, for example, half of the length of the room can be used as the preset control distance. For example, if the length of the room is 8 meters, the preset control distance can be set to 4 meters.

[0068] The size between the actual distance and the second control distance is judged. When the actual distance is less than the second control distance, it means that the current user is relatively close to the air conditioner. The indoor air outlet angle can be adjusted, such as controlling the upper and lower air guide strips and the left and right air guide strips of the air conditioner to change the indoor air outlet angle, so as to avoid the wind blowing directly on the user and achieve the wind avoiding the person. In addition, the speed of the indoor fan can be controlled to improve the user's comfort. For example, the indoor fan speed can be adjusted according to the second control distance, such as through a preset second control distance-indoor fan speed table. In this table, multiple second control distances and indoor fan speeds are stored. After determining a second control distance, the corresponding indoor fan speed can be determined.

[0069] Furthermore, it can also be determined by the above formula (1), where, in the wind avoidance mode, d i For the second control distance, for example, when the second control distance is determined to be 4 meters according to the length of the room, the indoor unit fan speed can be determined according to the actual distance d from the user to the air conditioner, and the smaller the actual distance d, the smaller the calculated wind speed, and when the actual distance d is larger, the calculated wind speed is larger. That is, when the user is closer to the air conditioner, a smaller wind speed can be used to cool or heat the user, so as to avoid the situation where the user can still feel some wind when the wind speed is too high even if the user sets the wind to avoid people. When the user is far away from the air conditioner, the wind speed can be made higher. As the air-conditioned wind diffuses, it becomes a gentler wind speed when it blows to the user's body surface, which can meet the comfortable environment required by the human body.

[0070] According to an embodiment of the present invention, adjusting the indoor air outlet angle includes: obtaining a height difference and an offset angle between a user and an air conditioner; adjusting the air outlet angle of the air conditioner in the vertical direction according to the height difference, and adjusting the air outlet angle of the air conditioner in the horizontal direction according to the offset angle, so as to achieve wind blowing on people or wind avoiding people in the corresponding mode. The height difference and the offset angle can be obtained based on the received UWB signal on the user side.

[0071] Specifically, when adjusting the indoor air outlet angle, the height difference and offset angle between the user and the air conditioner can be obtained first, for example, Figure 2 As shown, the UWB sensor on the user side can determine the user's position as (x, y), and the UWB sensor on the air conditioner side can determine the position of the air conditioner as (x 0 ,y 0 ), the actual distance between the user and the air conditioner is d, and when positioning, positioning can be completed through two UWB antennas, and the antenna position deployment is flexible and simple. The height difference between the user and the air conditioner is the height difference between the coordinates of the two points, that is, the height difference h can be y 0 -y's absolute value. The offset angle of the two coordinate points can be calculated accordingly through the properties of trigonometric functions. After determining the height difference and the offset angle, the air outlet angle of the air conditioner in the vertical direction can be adjusted according to the height difference, and the air outlet angle of the air conditioner in the horizontal direction can be adjusted according to the offset angle. For example, the air outlet angle in the vertical direction can be adjusted by controlling the upper and lower air guide strips of the air conditioner, and the air outlet angle in the horizontal direction can be adjusted by controlling the left and right air guide strips of the air conditioner, so that the wind of the air conditioner blows up and down and left and right to achieve the corresponding mode of wind blowing on people or wind avoiding people.

[0072] For example, Figure 2 α represents the horizontal deflection angle, which can be changed by changing the upper and lower air guide strips; β represents the vertical deflection angle, which can be changed by changing the left and right air guide strips. In the wind blowing people mode, it is only necessary to keep the upper and lower air guide strips and the left and right air guide strips so that the angles are within the range of α and β to achieve the wind blowing people out; in the wind avoiding people mode, it is only necessary to keep the upper and lower air guide strips and the left and right air guide strips so that the angles are not within the range of α and β to achieve the wind avoiding people out. Therefore, by setting the corresponding sensors in the air conditioner, the positioning accuracy is high, which can effectively avoid the misjudgment of the action of the air guide strip of the air conditioner due to low distance and positioning accuracy when the user moves at a fast speed, and the problem of slow response speed of the air guide strip.

[0073] Combine the following Figure 3 and Figure 4 The control method of the present invention will be described.

[0074] As a specific example, in the wind blowing mode, the control method of the air conditioner of the present invention may include the following steps:

[0075] S101, in the wind blowing mode, obtaining the user's body surface temperature, the indoor environment temperature and the actual distance between the user and the air conditioner.

[0076] S102, obtaining the absolute temperature difference between the user's body surface temperature and the indoor environment temperature.

[0077] S103, determining a first control distance according to the absolute temperature difference and a preset relationship table.

[0078] S104, determine whether the actual distance is less than the first control distance. If yes, execute step S105; if no, execute step S101.

[0079] S105, obtaining the height difference and offset angle between the user and the air conditioner.

[0080] S106, adjusting the air outlet angle of the air conditioner in the vertical direction according to the height difference, and adjusting the air outlet angle of the air conditioner in the horizontal direction according to the offset angle.

[0081] S107, adjusting the speed of the indoor fan according to the first control distance to achieve wind blowing on people.

[0082] As a specific example, in the wind avoidance mode, the control method of the air conditioner of the present invention may include the following steps:

[0083] S201, in the wind avoidance mode, obtaining the actual distance between the user and the air conditioner.

[0084] S202, determine whether the actual distance is less than the preset control distance. If yes, execute step S203; if not, execute step S201.

[0085] S203: Obtain the height difference and offset angle between the user and the air conditioner.

[0086] S204: adjusting the air outlet angle of the air conditioner in the vertical direction according to the height difference, and adjusting the air outlet angle of the air conditioner in the horizontal direction according to the offset angle.

[0087] S205, adjusting the speed of the indoor fan according to the second control distance to achieve wind avoiding people.

[0088] In summary, according to the control method of the air conditioner of the embodiment of the present invention, in the wind blowing people mode, the first control distance is determined according to the user's body surface temperature and the indoor environment temperature, and the air conditioner is controlled according to the actual distance between the user and the air conditioner and the first control distance to achieve wind blowing people; and / or, in the wind avoiding people mode, the air conditioner is controlled according to the actual distance between the user and the air conditioner and the second control distance to achieve wind avoiding people, wherein the second control distance is a preset control distance.
