References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0057] This application proposes a heating method based on air circulation, see Figures 1 to 8 The air circulation-based heating method is applied to the control device of the heating system, the heating system is used to heat the room, the heating system includes a temperature sensor and multiple heating components, each of the heating components has a heating component and an air blowing device, the number of the electric heating devices is equal to the number of the air blowing devices, and the electric heating devices are arranged on the air outlet side of the air blowing device.

[0058] The heating assembly further comprises an air suction device. In a preferred embodiment, each heating assembly comprises an air suction device, and the number of the electric heating devices is equal to the number of the air blowing devices and the number of the air suction devices.

[0059] During the use of the heating system, when a user enters a room and the ambient temperature of the room is low, the user needs to be heated by the heating component. When heating the user, in order to improve the heating efficiency, the electric heating device and the air blowing device are usually used at the same time. Specifically, the electric heating device first heats the air, and then blows the heated air to the user through the air blowing device. The heated air is then absorbed by the air suction device in another heating component, thereby accelerating the flow of air and improving the heating efficiency.

[0060] Wherein, the heating method based on air circulation includes:

[0061] S10, controlling the temperature sensor to obtain the ambient temperature of the room.

[0062] S20: When the ambient temperature is lower than a preset temperature, control the distance sensor to obtain distance information from the user.

[0063] The preset temperature is 15 degrees, 20 degrees or other temperatures.

[0064] Among them, when the ambient temperature of the room is lower than the preset temperature and a user enters the room, it means that the room and the user need to be heated. Therefore, when heating is needed, the first target heating component and the second target heating component for the heating component are determined.

[0065] The room includes a plurality of distance sensors, which are respectively arranged at different positions of the room, so as to ensure that when a user enters the room, the distance information of the user can be determined by the plurality of distance sensors, so as to provide targeted heating to the user.

[0066] Among them, such as Figure 1 As shown, the distance information can be represented by the distance information detected by the distance sensor. Specifically, the number of distance sensors in the room is greater than the number of walls in the room. In a preferred embodiment, the number of walls in the room is equal to the number of distance sensors. In one specific embodiment, the number of walls in the room is four, so the number of distance sensors in the room is four. The distance information is represented by the distance of each distance sensor.

[0067] Specifically, the room has four walls, and the room is equipped with four distance sensors, each of which is located on one side wall of the room. When a user enters the room, the four distance sensors detect the distance between themselves and the user, and the distance information is represented by the distance information obtained by each distance sensor.

[0068] In one embodiment, Figure 2 As shown, the room includes distance sensor A, distance sensor B, distance sensor C and distance sensor D. Distance sensor A, distance sensor B, distance sensor C and distance sensor D respectively detect the distance between them and the user. Then, the distance between the user and distance sensor A is 60 cm, the distance between the user and distance sensor B is 150 cm, the distance between the user and distance sensor C is 270 cm, and the distance between the user and distance sensor D is 350 cm.

[0069] S30, controlling the image acquisition device to acquire a user image of the user;

[0070] S40: Determine facial feature information of the user image.

[0071] The facial feature information includes the number of facial features, and the number of facial features is 0, 1, 2 or other numbers.

[0072] In addition, in order to improve the heating efficiency of the room, the control device also determines the user's facial image information through the image acquisition device. Specifically, the image acquisition device is arranged close to the distance sensor, and the number of the image acquisition devices is equal to the number of the distance sensors. The image acquisition device is used to capture user images.

[0073] To improve the heating effect on the user and prevent hot air from directly or indirectly blowing onto the user's face, the hot air flow generated by the heating component needs to be directed away from the user's face. Specifically, to determine the direction the user is facing, the image capture device can be used to determine the user's orientation by determining the number of facial features of the user. In one embodiment, the facial features include eye features, nose features, and mouth features. When the user is facing the image capture device head-on, the image capture device captures five facial features. When the user is facing the image capture device sideways, the image capture device captures one, two, three, or four facial features.

[0074] S50: Determine a first target heating component and a second target heating component according to the distance information and the facial feature information; the first target heating component and the second target heating component are different heating components.

[0075] The first target heating component is used to heat the air and blow the heated air toward the user, and the second target heating component is used to extract the air blown toward the user, thereby accelerating the airflow circulation.

[0076] In an alternative embodiment, determining the first target heating component and the second target heating component according to the distance information and the facial feature information includes:

[0077] S51. Determine at least one of the first target heating components according to the facial feature information.

[0078] Among them, in order to prevent the hot air flow generated by the heating component from directly blowing on the user's face, first determine the number of facial features corresponding to each image acquisition device.

[0079] In an alternative embodiment, the facial feature information includes the number of facial features. Determining at least one of the first target heating components according to the facial feature information includes:

[0080] S511. When the number of facial features is greater than or equal to a first preset number, determine the corresponding heating component as a non-target heating component;

[0081] S512. When the number of facial features is less than the first preset number, determine the distance information between the corresponding heating component and the user.

[0082] S513. Determine the first target heating component according to the distance information between the heating component and the user and a second preset number.

[0083] Among them, the first preset number is 1, 2 or other numbers, and the first preset number is less than or equal to 4.

[0084] Among them, the second preset number is 1, 2 or other numbers, and the second preset number is less than the total number of heating components in the room.

[0085] In another alternative embodiment, in the alternative embodiment, the facial feature information includes the number of pixel points of facial features, specifically including the number of pixel points of eyes, the number of pixel points of nose, and the number of pixel points of mouth. Determining at least one of the first target heating components according to the facial feature information may further include:

[0086] S514. Determine the number of pixel points of eyes, the number of pixel points of nose, and the number of pixel points of mouth in the user image;

[0087] Among them, in order to facilitate the determination of the user's facial feature information, first, it is necessary to judge the eye area, nose area, and mouth area in the user image according to the image recognition function of the control device, and then determine the number of pixel points in the eye area, nose area, and mouth area.

[0088] S515. Determine the heating priority of the heating component according to the first formula Q=[N2 / (N1+10)]*0.4+[N3 / (N1+10)]*0.6, the number of eye pixels, the number of nose pixels, and the number of mouth pixels, where N1 is the number of eye pixels, N2 is the number of nose pixels, and N3 is the number of mouth pixels.

[0089] Among them, when the user faces the heating component, the image acquisition device corresponding to the heating component collects more facial feature information. When the user faces the side of the heating component, the heating component can only collect partial eye feature information or partial mouth feature information. Therefore, the user's orientation can be determined by the number of pixels in different parts.

[0090] In a specific embodiment, in the user image captured by the image acquisition device corresponding to the heating component a1, N1 is 240 pixels, N2 is 450 pixels, and N3 is 340 pixels, then the heating priority of the heating component a1 is 1.536.

[0091] In another specific embodiment, in the user image captured by the image acquisition device corresponding to the heating component a2, N1 is 210 pixels, N2 is 45 pixels, and N3 is 50 pixels, then the heating priority of the heating component a2 is 0.218.

[0092] S516: Determine at least one target heating component according to the heating priority of each heating component.

[0093] After determining the heating priority of each heating component, if one first-target heating component is needed, the heating component with the highest heating priority is determined as the first-target heating component. If two first-target heating components are needed, the heating components with the highest and second highest heating priorities are determined as the first-target heating components, and so on.

[0094] S52: Determine the second target heating component according to the distance information between the first target heating component and the user.

[0095] Among them, in order to facilitate the adjustment and control of the heating components in the room, after the heating components are installed, the relative positions between each heating component are determined. Specifically, the preset position information between each heating component can be represented by the distance information with other heating components.

[0096] Specifically, the room includes heating components a1, a2, a3, and a4. Then, the position information of heating component a1 can be represented by the distances from other heating components. In a specific embodiment, the preset position information of heating component a1 can be expressed as (180, 220, 205).

[0097] Among them, after determining the single target heating component, in order to determine the second target heating component, it is necessary to first determine the position information of each of the first target heating components.

[0098] In an alternative embodiment, the determining a second target heating component according to the preset position information of the first target heating component and the positions of other heating components includes:

[0099] S521, if the number of the first target heating components is one, determine the heating component that is the farthest from the first target heating component and has a suction device as the second target heating component;

[0100] S522, if the number of the first target heating components is multiple, determine the sum of the distances between each of the other heating components with a suction device except the first target heating components and each of the first target heating components; and determine the heating component with the largest sum of distances as the second target heating component.

[0101] Among them, as Figure 3 shown, the room includes heating components a1, a2, a3, a4, and a5. When the first target heating component is heating component a2, first determine the preset position information of heating component a2 as (40, 150, 270, 320). Therefore, it is determined that the distance between heating component a2 and heating component a5 is the farthest. Therefore, heating component a5 is determined as the second target heating component.

[0102] S60, determine a first heating parameter according to the ambient temperature and the distance information between the first target heating component and the user.

[0103] Among them, after using the first target heating component and determining the distance information between the first target heating component and the user, it is necessary to determine an appropriate first heating parameter so that the first target heating component heats the user.

[0104] In an alternative embodiment, the heating parameter includes the heating power of the electric heating device and the blowing power of the blowing device. The determining a first heating parameter according to the ambient temperature and the distance information between the first target heating component and the user includes:

[0105] According to the second formula W1 = 50 * |R - R1| * (0.8 + T / 200), the environmental temperature determines the heating power, where R is the environmental temperature, R1 is the first preset temperature, W1 is the heating power, and T is the distance information between the user and the first target heating component. The preset temperature is 10 degrees, 15 degrees or other temperatures.

[0106] According to the third formula W2 = 30 * |R - R1| * (T / 220), the distance information determines the blowing power, where W2 is the blowing power, R is the environmental temperature, R1 is the preset temperature, and T is the distance information between the user and the first target heating component.

[0107] In a specific embodiment, the distance information T between the user and the first target heating component is 60 cm. When the environmental temperature R detected by the temperature sensor is 19 °C and the preset temperature R1 is 20 °C, then according to the second formula, the heating power W1 is 55 watts, and according to the third formula, the blowing power W2 is 8.18 watts.

[0108] S70, determine the second heating parameter according to the first distance between the second target heating component and the first target heating component, where the first distance is the sum of the distances between the second target heating component and the first target heating component.

[0109] Wherein, the second heating parameter includes the suction power. After determining the first heating parameter, in order to improve the circulation of hot air in the heating system, it is also necessary to further determine the second heating parameter.

[0110] In an alternative embodiment, according to the fourth formula W3 = W2 * (1 + S / 200), the blowing power and the first distance between the second target heating component and the first target heating component determine the suction power, where W3 is the suction power, W2 is the blowing power, and S is the first distance between the second target heating component and the first target heating component.

[0111] In a specific embodiment, the first distance S is 530 cm and the blowing power W2 is 8.18 watts. Then according to the fourth formula, the suction power W3 is 29.86 watts.

[0112] S80, the first target heating component heats the user according to the first heating parameter, and the second target heating component heats the user according to the second heating parameter.

[0113] Among them, after determining the first heating parameter and the second heating parameter, the control device controls the electric heating device and the blowing device of the first target heating component to blow the heated air to the user, and at the same time, the control device controls the suction device of the second target heating component to extract the heated air, so as to improve the user's perceived temperature while increasing the air flow of the heated air, thereby improving the heating flexibility and heating efficiency of the heating system.
