[0002] With the increasing requirements for comfort, there have been more and more innovations in the comfort control of air conditioner products, such as air supply methods like waterfall cooling and carpet heating. Its basic control principle is to utilize the characteristics that cold air sinks and hot air rises, which not only accelerates the cooling and heating effects of the space but also enhances the comfort experience of users.

[0003] The duct machine products that achieve waterfall cooling and carpet heating can control the air outlet at the ceiling or at the floor. The product has an upper air outlet located in the upper part of the room and a lower air outlet located in the lower part of the room. In order to detect the temperature field state and personnel situation of the entire room, an infrared thermopile sensor will be added to achieve this function. And in order to better detect the situation of the room, the sensor is generally placed at the upper air outlet because the field of vision is wider. And in order to save costs, sensors are generally not added to the lower air outlet. Even if a sensor is set at the lower air outlet, if the sensor fails, the sensor at the lower air outlet cannot be used for detection. If there is no sensor at the lower air outlet or the sensor at the lower air outlet fails. When the unit needs to use the lower air outlet for air supply due to functional logic, the lower air outlet cannot detect the temperature field and personnel situation of the room, so a series of comfort controls such as air supply following people or avoiding people cannot be achieved.

[0013] Further, before detecting whether the air conditioner blows air from the second air outlet, it further includes: listening for whether user comfort control is triggered; wherein, the user comfort control is used to implement air-following-human blowing control or air-avoiding-human blowing control, the air-following-human blowing control blows air according to the air outlet angle of the second air outlet, and the air-avoiding-human blowing control blows air according to the air-avoiding-human air outlet angle; if so, trigger the detection of whether the air conditioner blows air from the second air outlet.

[0025] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0026] Embodiment 1

[0027] In a preferred Embodiment 1 of the present invention, an air conditioner control method is provided. This control method can be directly applied to various air conditioners, especially duct machines with up-and-down air outlet functions, or duct machines with other reversible air outlet functions. Preferably, the duct machine is usually installed on an indoor wall, including a side air outlet and an upper air outlet located at the upper part of the wall. In addition, a lower air outlet is also installed at the bottom of the wall. The method in the present invention mainly relates to the upper air outlet (the first air outlet) and the lower air outlet (the second air outlet). When cooling, air blows out from the first air outlet. When heating, air blows out from the second air outlet, and the hot air is sent into the room through the air duct in the wall.

[0028] Specifically, Figure 1 An optional flowchart showing the method is as Figure 1 shown, and the method includes the following steps S102 - S106:

[0029] S102: Detect whether the air conditioner blows out air from the second air outlet;

[0030] S104: If so, detect the position of the target object through the sensor at the first air outlet;

[0031] S106: Calculate the air outlet angle of the second air outlet according to the position of the target object, and control the air outlet of the second air outlet according to the air outlet angle of the second air outlet.

[0032] In the above embodiment, an air conditioner control solution for improving comfort is provided. When the unit switches to blow out air from the lower air outlet according to the logical requirement, the sensor at the upper air outlet is used to detect the temperature field of the room to confirm the position of the person, and then it is converted into the spatial position of the lower air outlet through conversion, so as to realize comfort control such as air blowing with or avoiding people. Through the above solution, the problem that the comfort control cannot be realized when the lower air outlet of the air conditioner blows out air in the prior art can be effectively solved, and the comfort experience of the user is improved.

[0033] The unit is powered on, and the infrared sensor normally detects the temperature field distribution in the room. The detection of the room temperature field and the personnel position is not limited to the infrared sensor, but also includes various detection methods such as millimeter-wave radar. If there is a target object in the room, such as a person, the position coordinates (x1, y1) of the person are marked; as Figure 2 shown, the coordinate origin of the position coordinates of the target object is located at the center of the second air outlet. The unit calculates the air outlet angle of the first air outlet according to the height difference h between the first air outlet (corresponding to the upper air outlet in Figure 2-4 ) and the second air outlet (corresponding to the lower air outlet in Figure 2-4 ), the projection coordinates of the person, and other data. The vertical air outlet angle is θ1. Preferably, the vertical air outlet angle is the upper and lower air outlet angles, and the horizontal air outlet angle is α1. Preferably, the horizontal air outlet angle is the left and right air outlet angles; Figure 2 shows the side view schematic diagram of the air outlet of the upper air outlet. As Figure 2 shown:

[0034] tan(θ + θ1) = y2 / h; where y2 is the distance between the intersection of the straight line determined by the first air outlet and the top of the target object and the ground and the second air outlet.

[0035] tanθ = y1 / h;

[0036] Therefore, the vertical air outlet angle θ1 of the first air outlet is calculated according to the position of the target object, θ1 = arctan(y2 / h) - arctan(y1 / h).

[0037] Figure 3 shows the top view schematic diagram of the air outlet of the upper air outlet. Usually, the first air outlet and the second air outlet are coincidentally arranged. Therefore, Figure 3 it is also the top view schematic diagram of the left and right air outlets of the second air outlet. As Figure 3 shown:

[0038] tan(α + α1) = y2 / x2;

[0039] tanα = y1 / x1;

[0040] x1 = x2;

[0041] Therefore, the horizontal air outlet angle α1 of the first air outlet is calculated by the following formula: α1 = arctan(y2 / x1) - arctan(y1 / x1). And α1 = α2.

[0042] The unit controller converts the air outlet angle calculated by the first air outlet into the air outlet angle of the second air outlet, where the vertical air outlet angle is θ2 and the horizontal air outlet angle is α2. Figure 4 shows the side view schematic diagram of the up and down air outlets of the upper air outlet and the lower air outlet. As Figure 4As shown:

[0043] h1 / h = (y2 - y1) / y2; wherein, the height difference h between the first air outlet and the second air outlet can be obtained by setting or detected by other sensors.

[0044] tanθ2 = h1 / y1;

[0045] Therefore, the vertical air outlet angle θ2 of the second air outlet is calculated by the following formula:

[0046] θ2 = arctan(h1 / y1).

[0047] After determining the air outlet angle of the second air outlet, controlling the air outlet of the second air outlet according to the air outlet angle of the second air outlet includes: blowing air according to the air outlet angle of the second air outlet for air following person control; or, calculating the air avoiding person air outlet angle according to the air outlet angle of the second air outlet; wherein, the air avoiding person air outlet angle is the complete air outlet angle of the second air outlet minus the air outlet angle of the second air outlet; blowing air according to the air avoiding person air outlet angle. The complete air outlet angle is the maximum air outlet angle that the second air outlet can achieve. When calculating the vertical air outlet angle, the complete air outlet angle is the maximum air outlet angle that the second air outlet can achieve in the vertical direction. When calculating the horizontal air outlet angle, the complete air outlet angle is the maximum air outlet angle that the second air outlet can achieve in the horizontal direction. Preferably, the complete air outlet angle of the air duct machine is 180°.

[0048] Further, before detecting whether the air conditioner blows air from the second air outlet, it further includes: monitoring whether user comfort control is triggered; wherein, the user comfort control is used to achieve air following person blowing control or air avoiding person blowing control. The air following person blowing control blows air according to the air outlet angle of the second air outlet, and the air avoiding person blowing control blows air according to the air avoiding person air outlet angle; if so, trigger the detection of whether the air conditioner blows air from the second air outlet. The control scheme of comfort is not limited to air following person and avoiding person, but also includes various comfort controls such as temperature field adjustment.

[0049] Through the above conversion and switching operation of the air outlet angle, the infrared sensor of the upper air outlet can be used to detect the human body position, and then control the up and down air outlet and left and right air outlet of the lower air outlet to achieve air following person and avoiding person, ensuring the comfort of the user in the lower air outlet state of the unit.
