In recent years, home appliance companies and kitchen appliance companies have launched targeted air conditioning or kitchen appliance products to address the high temperature, high humidity and high oil content of the kitchen environment.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] According to an embodiment of the present invention, a control method for an air conditioner is provided. The air conditioner includes an indoor unit and an outdoor unit. The air conditioner has a fresh air function. The indoor unit has an indoor fan and a fresh air fan. The air delivered by the fresh air fan can form an air wall at any location in the indoor environment, and the air wall can block temperature conduction. The indoor unit also has an indoor fan outlet and a fresh air fan outlet. Specifically, the air conditioner can activate the fresh air function while in cooling mode. The fresh air function delivers air through the fresh air fan outlet, while the cooling mode delivers air through the indoor fan outlet. Figure 1 The diagram shows a flowchart of an embodiment of the method of the present invention. The air conditioner control method may include steps S110 to S130.

[0028] In step S110, when the air conditioner is turned on and running in cooling mode, the location and temperature of the heat-generating electrical equipment in the room, the location and body temperature of the user of the air conditioner, and the ambient temperature between the heat-generating electrical equipment and the user are obtained.

[0029] The air conditioner is equipped with a radar module and a WiFi module. The radar module can obtain the size of the kitchen space and the location information of various heat-generating appliances within the room. For example, taking the location of the air conditioner as the spatial origin O, assuming there are a rice cooker, a steam oven, and a gas stove in the kitchen, the radar module can determine the specific location of the rice cooker (X1, Y1, Z1), the steam oven (X2, Y2, Z2), and the gas stove (X3, Y3, Z3). If the heat-generating appliances are equipped with temperature and humidity sensors and WiFi modules, the temperature and humidity conditions at their locations can be obtained through the temperature and humidity sensors. Furthermore, by exchanging data with other smart terminals through the WiFi module, the relative distance of other smart terminals to the air conditioner can be determined. For example, the rice cooker transmits a command or information to the air conditioner's WiFi receiving module via its WiFi module. After receiving the information, the air conditioner can calculate the relative distance between the location that sent the command and the location that received the command (this distance is the time from sending the command to receiving the command multiplied by the signal transmission rate).

[0030] Based on the calculated relative distance and the location information of the heat-generating electrical appliance obtained by the radar module, the spatial distance of the heat-generating electrical appliance from the spatial origin O can be determined. Therefore, the air conditioner can use its internal WiFi and radar modules to obtain the specific location of each smart home appliance.

[0031] The air conditioner is also equipped with an infrared thermal imaging module, which can acquire the temperature of all objects in the kitchen, including people, as well as the temperature of various locations. Specifically, it can acquire real-time thermal information of the location of heat-generating electrical appliances and people, thereby obtaining the required temperature information and the location of the user.

[0032] In addition, the location information of the acquired electrical appliances is created in a 3D model of the kitchen scene. This allows for an intuitive description and calculation of the distance between the human body and different appliances. When the radar acquires the location of the human body, it can determine which appliances are nearby. At the same time, detecting temperature information can identify which appliances in the kitchen environment are working and affecting the human body temperature. This makes it easier for the air wall to precisely blow and block the heat source, achieving more targeted and precise heat blocking and temperature adjustment.

[0033] In step S120, the position of the air wall formed by the air delivered by the fresh air fan is controlled according to the position and temperature of the heat-generating electrical device and the position of the user, so that the air wall is positioned between the heat-generating electrical device and the user.

[0034] Specifically, based on the location of the heat-generating electrical appliance and the user's location, it can be determined in which direction the heat-generating electrical appliance affects the user's body temperature, thereby determining the specific direction the airflow should be directed relative to the user. For example, if there is a heat-generating electrical appliance to the user's left, the airflow should be positioned to the user's left to block the heat source.

[0035] Furthermore, based on the location and temperature of the heat-generating electrical device, as well as the user's location, it can be determined whether to activate the airflow barrier and the distance between the barrier and the user. Specifically, when the heat-generating electrical device is far from the user and emits little heat, the user will not feel it, so an airflow barrier is not required. When the heat-generating electrical device is close to the user, or emits a significant amount of heat that could affect the user's body temperature, an airflow barrier is deployed at a specific distance between the user and the electrical device, ensuring both the insulation effect of the barrier and preventing it from blowing directly on the user.

[0036] In step S130, the cooling rate of the air conditioner is controlled according to the user's body temperature; at the same time, the fan speed of the fresh air fan is controlled according to the ambient temperature of the position between the heat-generating electrical device and the user, so that the air wall blocks the heat emitted by the heat-generating electrical device.

[0037] The solution of this invention, in cooling mode, simultaneously delivers cold air and fresh air. The cold air directly cools the user, while the fresh air forms an airflow barrier to block heat dissipation from other heat-generating devices in the environment, preventing any impact on the user. This solves the problem of uneven air conditioning cooling and user discomfort caused by continuous heating from indoor heat sources in specific environments. By regulating indoor air temperature and quality, it keeps the user's perceived temperature within a comfortable range, improving the user experience.

[0038] In some implementations, when the air conditioner is operating in cooling mode, the air blown by the indoor fan is directed toward the user of the air conditioner.

[0039] In some implementations, the specific process of controlling the cooling rate of the air conditioner based on the user's body temperature in step S130 is as follows: Figure 2 As shown, it includes steps S210 to S230.

[0040] Step S210: Determine the range of the difference between the user's body temperature and the first set temperature.

[0041] Step S220: Determine the new cooling rate of the air conditioner based on the range of the difference between the user's body temperature and the first set temperature.

[0042] Step S230: Control the operating state of the air conditioner so that the cooling rate of the air conditioner is the new cooling rate.

[0043] Specifically, when the user's body temperature T 测 With the first set temperature T 设1 If the difference ΔT1 is within the first range, which is less than or equal to 5℃, then the cooling rate of the air conditioner remains unchanged; that is, the new cooling rate is still the current cooling rate. When the user's body temperature T... 测 With the first set temperature T 设1 If the temperature difference ΔT1 falls within the second range (greater than 5°C and less than 10°C), then the new cooling rate of the air conditioner is 1.5 times the current cooling rate; when the user's body temperature T... 测 With the first set temperature T 设1 If the difference ΔT1 is in the third range, which is greater than or equal to 10℃, then the new cooling rate of the air conditioner is twice the current cooling rate.

[0044] Cooling rate represents the cooling capacity of an air conditioner. There are many ways to change the cooling rate, such as adjusting the indoor fan speed, adjusting the compressor frequency, and adjusting the opening of the throttling device. Using these methods, the supply air temperature and velocity at the indoor fan outlet can be adjusted. These supply air temperatures and velocities can be quantified. Based on the supply air temperature and velocity at the indoor fan outlet, the air conditioner's cooling rate can be adjusted to a specific value or a specific multiple of the original cooling rate. For example, at the initial cooling rate, the indoor fan supply air temperature is T0, and the supply air velocity is v0; when the cooling rate is changed to 1.5 times the original, the indoor fan supply air temperature is T0-T1.5, and the supply air velocity is v0+V1.5; when the cooling rate is changed to 2 times the original, the indoor fan supply air temperature is T0-T2, and the supply air velocity is v0+V2; where T1.5, T2, V1.5, and V2 are fixed constants obtained from actual experiments.

[0045] In addition, to more directly lower the user's body temperature, the air conditioner also features a "follow-the-person" function, meaning the direction of the cool air can change according to the user's position, always blowing directly on the user. Preferably, the air conditioner is installed in the center of the room, with air outlets in all four directions of the indoor unit, thus more effectively utilizing the "follow-the-person" function to directly cool the user.

[0046] This solution directs the cool air from the air conditioner directly to the user and adjusts the cooling rate of the air conditioner in real time according to the body temperature, thereby achieving a good cooling effect, reducing the impact of heat-generating electrical equipment on the user's body temperature, and making the user's perceived temperature more comfortable.

[0047] In some embodiments, the specific process of controlling the fan speed of the fresh air blower in step S130 based on the ambient temperature at the location between the heating electrical device and the user is as follows: Figure 3 As shown, it includes steps S310 to S330.

[0048] Step S310: Record the temperature at a position between the heating electrical device and the user at a preset distance from the user as the first temperature; determine the range of the difference between the first temperature and the second set temperature.

[0049] Step S320: Determine the new fan speed of the fresh air fan based on the range of the difference between the first temperature and the second set temperature.

[0050] Step S330: Control the fresh air fan to operate according to the new fan speed.

[0051] Preferably, the temperature at the location of the windbreak is set as a first temperature, meaning the wind force of the windbreak is controlled based on the temperature at the windbreak location. Specifically, when the first temperature is greater than or equal to a second set temperature T... 设2 If the difference ΔT2 is within a first range, which is less than or equal to 5°C, then the fan speed of the fresh air blower controlling the airflow between the heat-generating electrical equipment and the user is set to low; when the first temperature and the second set temperature T... 设2 If the difference ΔT2 falls within the second range (greater than 5°C and less than 10°C), then the fan speed of the fresh air blower controlling the airflow between the heat-generating electrical equipment and the user is set to medium speed; when the first temperature and the second set temperature T... 设2 If the difference ΔT2 is in the third range, which is greater than or equal to 10℃, then the fan speed of the fresh air fan that controls the airflow between the heat-generating electrical equipment and the user is set to high speed.

[0052] In some embodiments, the air delivered by the fresh air fan can form n air walls, which can block the heat emitted by the heating electrical appliances in front of, behind, to the left and right of the user; the size of the air damper of each of the n air walls can be controlled according to the user's body temperature and the ambient temperature between the user and the heating electrical appliances in the direction of the n air walls, where n is a positive integer.

[0053] Because kitchen environments typically contain numerous heat-generating electrical appliances, n air vents are used to effectively block heat, surrounding the user and preventing heat transfer between them and other heat sources in the room. This avoids the heat radiating from these sources affecting the user. For example, air vents can be positioned to the user's left, back, left, and right. The speed of the fresh air fan generating each air vent can be independently adjusted, intelligently regulating the size of the air vent based on the distance and heat generation of the heat source in that direction, ensuring heat isolation while minimizing unnecessary energy waste.

[0054] For conventional wall-mounted and floor-standing air conditioners, the air outlets can be divided into zones, with each zone having its own independent actuator, allowing each outlet to work independently and thus creating multiple fresh air walls simultaneously.

[0055] This solution blocks the heat source's conduction path by setting up multiple airflow barriers around the user, each with individually adjustable airflow, thus preventing uneven body temperature and discomfort caused by heat affecting the user's body temperature.

[0056] Figure 5 This is a flowchart illustrating an embodiment of the air conditioner cooling rate and fresh air fan speed control method of the present invention, as shown below. Figure 5As shown, the method of the present invention includes:

[0057] Step 1: When the air conditioner is turned on and running in cooling mode, the radar module scans the size of the kitchen space and the positions of different products and items, sending the product codes of different heating appliances to the air conditioner. Once the air conditioner receives the code information, it calculates the distance between the corresponding product and the air conditioner, matching the radar-scanned product's position with the calculated distance to obtain the precise location of the heating product. Simultaneously, the infrared thermal imaging module scans the kitchen, generating thermal imaging information for different items. The precise location of the heating product and the thermal imaging information are output to the real-time environment model, generating a 3D model of the kitchen environment, thereby determining the location of the air vent wall. Then, steps 2 and 3 are executed.

[0058] Step 2: Using the temperature information from the generated 3D model, determine the relationship between the human body temperature in the kitchen and the set temperature, and control the air conditioner's cooling rate accordingly. Specifically, when the measured human body temperature is ≥ the set temperature + 10℃, the air conditioner's cooling rate is controlled at twice the current cooling rate; when the set temperature + 5℃ < the measured human body temperature < the set temperature + 10℃, the air conditioner's cooling rate is controlled at 1.5 times the current cooling rate; when the measured human body temperature is ≤ the set temperature + 5℃, the air conditioner's cooling rate is controlled at 1 times the current cooling rate.

[0059] Step 3: Using the temperature and position information from the generated 3D model, determine the relationship between the temperature of the four sides of the human body in the kitchen (front, back, left, and right) and the set temperature, and control the airflow level of the fresh air fans generating the corresponding airflow walls. Specifically, when the temperature on the left side of the human body is ≥ the set temperature + 10℃, the airflow level of the fresh air fan generating the left airflow wall is set to the strong airflow level; when the set temperature + 5℃ < the temperature on the left side of the human body < the set temperature + 10℃, the airflow level of the fresh air fan generating the left airflow wall is set to the medium airflow level; when the temperature on the left side of the human body is ≤ the set temperature + 5℃, the airflow level of the fresh air fan generating the left airflow wall is set to the low airflow level. Then, determine the temperature on the right side, front side, and back side of the human body separately, and control the corresponding airflow level of the fresh air fans.

[0060] The technical solution of this embodiment includes a fresh air fan installed at the indoor unit of the air conditioner. The air delivered by the fresh air fan forms an air wall. When the air conditioner is running in cooling mode, the position of the air wall formed by the air delivered by the indoor unit is controlled according to the location and temperature of the heat-generating electrical equipment and the user's location. The cooling rate of the air conditioner is controlled according to the user's body temperature. Simultaneously, the fan speed of the fresh air fan is controlled according to the ambient temperature between the heat-generating electrical equipment and the user. By lowering the user's temperature with cool air, the fresh air air wall isolates the heat emitted by the heat source, avoiding uneven perceived temperature and keeping the user's perceived temperature within a comfortable range, thus improving the user experience of the air conditioner.

[0061] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method of the air conditioner is also provided. The air conditioner includes an indoor unit and an outdoor unit; the air conditioner has a fresh air function; the indoor unit has an indoor fan and a fresh air fan; the air delivered by the fresh air fan can form an air wall at any location in the indoor environment, and the air wall can block temperature conduction; the indoor unit also has an indoor fan outlet and a fresh air fan outlet. Specifically, the air conditioner can activate the fresh air function while simultaneously operating in cooling mode. The fresh air function delivers air through the fresh air fan outlet, while the cooling mode delivers air through the indoor fan outlet. See also... Figure 4 The diagram shows a structural schematic of an embodiment of the device of the present invention. The control device for the air conditioner may include: an acquisition unit 102 and a control unit 104.

[0062] The acquisition unit 102 is configured to acquire, when the air conditioner is turned on and running in cooling mode, the location and temperature of the heat-generating electrical equipment in the room, the location and body temperature of the user of the air conditioner, and the ambient temperature at the location between the heat-generating electrical equipment and the user. The specific functions and processing of this acquisition unit 102 are described in step S110.

[0063] The air conditioner is equipped with a radar module and a WiFi module. The radar module can obtain the size of the kitchen space and the location information of various heat-generating appliances within the room. For example, taking the location of the air conditioner as the spatial origin O, assuming there are a rice cooker, a steam oven, and a gas stove in the kitchen, the radar module can determine the specific location of the rice cooker (X1, Y1, Z1), the steam oven (X2, Y2, Z2), and the gas stove (X3, Y3, Z3). If the heat-generating appliances are equipped with temperature and humidity sensors and WiFi modules, the temperature and humidity conditions at their locations can be obtained through the temperature and humidity sensors. Furthermore, by exchanging data with other smart terminals through the WiFi module, the relative distance of other smart terminals to the air conditioner can be determined. For example, the rice cooker transmits a command or information to the air conditioner's WiFi receiving module via its WiFi module. After receiving the information, the air conditioner can calculate the relative distance between the location that sent the command and the location that received the command (this distance is the time from sending the command to receiving the command multiplied by the signal transmission rate).

[0064] Based on the calculated relative distance and the location information of the heat-generating electrical appliance obtained by the radar module, the spatial distance of the heat-generating electrical appliance from the spatial origin O can be determined. Therefore, the air conditioner can use its internal WiFi and radar modules to obtain the specific location of each smart home appliance.

[0065] The air conditioner is also equipped with an infrared thermal imaging module, which can acquire the temperature of all objects in the kitchen, including people, as well as the temperature of various locations. Specifically, it can acquire real-time thermal information of the location of heat-generating electrical appliances and people, thereby obtaining the required temperature information and the location of the user.

[0066] In addition, the location information of the acquired electrical appliances is created in a 3D model of the kitchen scene. This allows for an intuitive description and calculation of the distance between the human body and different appliances. When the radar acquires the location of the human body, it can determine which appliances are nearby. At the same time, detecting temperature information can identify which appliances in the kitchen environment are working and affecting the human body temperature. This makes it easier for the air wall to precisely blow and block the heat source, achieving more targeted and precise heat blocking and temperature adjustment.

[0067] Control unit 104 is configured to control the position of the airflow wall formed by the fresh air fan based on the position and temperature of the heat-generating electrical appliance and the position of the user, so that the airflow wall is positioned between the heat-generating electrical appliance and the user. The specific functions and processing of this control unit 104 are described in step S120.

[0068] Specifically, based on the location of the heat-generating electrical appliance and the user's location, it can be determined in which direction the heat-generating electrical appliance affects the user's body temperature, thereby determining the specific direction the airflow should be directed relative to the user. For example, if there is a heat-generating electrical appliance to the user's left, the airflow should be positioned to the user's left to block the heat source.

[0069] Furthermore, based on the location and temperature of the heat-generating electrical device, as well as the user's location, it can be determined whether to activate the airflow barrier and the distance between the barrier and the user. Specifically, when the heat-generating electrical device is far from the user and emits little heat, the user will not feel it, so an airflow barrier is not required.

[0070] The control unit 104 is also configured to control the cooling rate of the air conditioner based on the user's body temperature; simultaneously, it controls the fan speed of the fresh air fan based on the ambient temperature at the location between the heat-generating electrical appliance and the user, so that the airflow barrier blocks the heat emitted by the heat-generating electrical appliance. For the specific functions and processing of this control unit 104, please refer to step S130.

[0071] The solution of this invention, in cooling mode, simultaneously delivers cold air and fresh air. The cold air directly cools the user, while the fresh air forms an airflow barrier to block heat dissipation from other heat-generating devices in the environment, preventing any impact on the user. This solves the problem of uneven air conditioning cooling and user discomfort caused by continuous heating from indoor heat sources in specific environments. By regulating indoor air temperature and quality, it keeps the user's perceived temperature within a comfortable range, improving the user experience.

[0072] In some implementations, when the air conditioner is operating in cooling mode, the air blown by the indoor fan is directed toward the user of the air conditioner.

[0073] In some embodiments, the control unit 104 controls the cooling rate of the air conditioner based on the user's body temperature, including:

[0074] The control unit 104 is further configured to determine the range of the difference between the user's body temperature and the first set temperature. The specific functions and processing of the control unit 104 are described in step S210.

[0075] The control unit 104 is further configured to determine a new cooling rate of the air conditioner based on the range of the difference between the user's body temperature and the first set temperature. The specific functions and processing of the control unit 104 are described in step S220.

[0076] The control unit 104 is further configured to control the operating state of the air conditioner so that the cooling rate of the air conditioner is the new cooling rate. The specific functions and processing of the control unit 104 are described in step S230.

[0077] Specifically, when the user's body temperature T 测 With the first set temperature T 设1 If the difference ΔT1 is within the first range, which is less than or equal to 5℃, then the cooling rate of the air conditioner remains unchanged; that is, the new cooling rate is still the current cooling rate. When the user's body temperature T... 测 With the first set temperature T 设1 If the temperature difference ΔT1 falls within the second range (greater than 5°C and less than 10°C), then the new cooling rate of the air conditioner is 1.5 times the current cooling rate; when the user's body temperature T... 测 With the first set temperature T 设1 If the difference ΔT1 is in the third range, which is greater than or equal to 10℃, then the new cooling rate of the air conditioner is twice the current cooling rate.

[0078] Cooling rate represents the cooling capacity of an air conditioner. There are many ways to change the cooling rate, such as adjusting the indoor fan speed, adjusting the compressor frequency, and adjusting the opening of the throttling device. Using these methods, the supply air temperature and velocity at the indoor fan outlet can be adjusted. These supply air temperatures and velocities can be quantified. Based on the supply air temperature and velocity at the indoor fan outlet, the air conditioner's cooling rate can be adjusted to a specific value or a specific multiple of the original cooling rate. For example, at the initial cooling rate, the indoor fan supply air temperature is T0, and the supply air velocity is v0; when the cooling rate is changed to 1.5 times the original, the indoor fan supply air temperature is T0-T1.5, and the supply air velocity is v0+V1.5; when the cooling rate is changed to 2 times the original, the indoor fan supply air temperature is T0-T2, and the supply air velocity is v0+V2; where T1.5, T2, V1.5, and V2 are fixed constants obtained from actual experiments.

[0079] In addition, to more directly lower the user's body temperature, the air conditioner also features a "follow-the-person" function, meaning the direction of the cool air can change according to the user's position, always blowing directly on the user. Preferably, the air conditioner is installed in the center of the room, with air outlets in all four directions of the indoor unit, thus more effectively utilizing the "follow-the-person" function to directly cool the user.

[0080] This solution directs the cool air from the air conditioner directly to the user and adjusts the cooling rate of the air conditioner in real time according to the body temperature, thereby achieving a good cooling effect, reducing the impact of heat-generating electrical equipment on the user's body temperature, and making the user's perceived temperature more comfortable.

[0081] In some embodiments, the control unit 104 controls the fan speed of the fresh air blower based on the ambient temperature at the location between the heat-generating electrical device and the user, including:

[0082] The control unit 104 is further configured to record the temperature at a preset distance between the heating electrical device and the user as a first temperature; and to determine the range of the difference between the first temperature and a second set temperature. The specific functions and processing of this control unit 104 are described in step S310.

[0083] The control unit 104 is further configured to determine a new fan speed for the fresh air fan based on the range of the difference between the first temperature and the second set temperature. The specific functions and processing of this control unit 104 are described in step S320.

[0084] The control unit 104 is further configured to control the fresh air fan to operate according to the new fan speed. The specific functions and processing of the control unit 104 are described in step S330.

[0085] Preferably, the temperature at the location of the windbreak is set as a first temperature, meaning the wind force of the windbreak is controlled based on the temperature at the windbreak location. Specifically, when the first temperature is greater than or equal to a second set temperature T... 设2 If the difference ΔT2 is within a first range, which is less than or equal to 5°C, then the fan speed of the fresh air blower controlling the airflow between the heat-generating electrical equipment and the user is set to low; when the first temperature and the second set temperature T... 设2 If the difference ΔT2 falls within the second range (greater than 5°C and less than 10°C), then the fan speed of the fresh air blower controlling the airflow between the heat-generating electrical equipment and the user is set to medium speed; when the first temperature and the second set temperature T... 设2 If the difference ΔT2 is in the third range, which is greater than or equal to 10℃, then the fan speed of the fresh air fan that controls the airflow between the heat-generating electrical equipment and the user is set to high speed.

[0086] In some embodiments, the air delivered by the fresh air fan can form n air walls, which can block the heat emitted by the heating electrical appliances in front of, behind, to the left and right of the user; the size of the air damper of each of the n air walls can be controlled according to the user's body temperature and the ambient temperature between the user and the heating electrical appliances in the direction of the n air walls, where n is a positive integer.

[0087] Because kitchen environments typically contain numerous heat-generating electrical appliances, n air vents are used to effectively block heat, surrounding the user and preventing heat transfer between them and other heat sources in the room. This avoids the heat radiating from these sources affecting the user. For example, air vents can be positioned to the user's left, back, left, and right. The speed of the fresh air fan generating each air vent can be independently adjusted, intelligently regulating the size of the air vent based on the distance and heat generation of the heat source in that direction, ensuring heat isolation while minimizing unnecessary energy waste.

[0088] For conventional wall-mounted and floor-standing air conditioners, the air outlets can be divided into zones, with each zone having its own independent actuator, allowing each outlet to work independently and thus creating multiple fresh air walls simultaneously.

[0089] This solution blocks the heat source's conduction path by setting up multiple airflow barriers around the user, each with individually adjustable airflow, thus preventing uneven body temperature and discomfort caused by heat affecting the user's body temperature.

[0090] Figure 5 This is a flowchart illustrating an embodiment of the air conditioner cooling rate and fresh air fan speed control method of the present invention, as shown below. Figure 5 As shown, the method of the present invention includes:

[0091] Step 1: When the air conditioner is turned on and running in cooling mode, the radar module scans the size of the kitchen space and the positions of different products and items, sending the product codes of different heating appliances to the air conditioner. Once the air conditioner receives the code information, it calculates the distance between the corresponding product and the air conditioner, matching the radar-scanned product's position with the calculated distance to obtain the precise location of the heating product. Simultaneously, the infrared thermal imaging module scans the kitchen, generating thermal imaging information for different items. The precise location of the heating product and the thermal imaging information are output to the real-time environment model, generating a 3D model of the kitchen environment, thereby determining the location of the air vent wall. Then, steps 2 and 3 are executed.

[0092] Step 2: Using the temperature information from the generated 3D model, determine the relationship between the human body temperature in the kitchen and the set temperature, and control the air conditioner's cooling rate accordingly. Specifically, when the measured human body temperature is ≥ the set temperature + 10℃, the air conditioner's cooling rate is controlled at twice the current cooling rate; when the set temperature + 5℃ < the measured human body temperature < the set temperature + 10℃, the air conditioner's cooling rate is controlled at 1.5 times the current cooling rate; when the measured human body temperature is ≤ the set temperature + 5℃, the air conditioner's cooling rate is controlled at 1 times the current cooling rate.

[0093] Step 3: Using the temperature and position information from the generated 3D model, determine the relationship between the temperature of the four sides of the human body in the kitchen (front, back, left, and right) and the set temperature, and control the airflow level of the fresh air fans generating the corresponding airflow walls. Specifically, when the temperature on the left side of the human body is ≥ the set temperature + 10℃, the airflow level of the fresh air fan generating the left airflow wall is set to the strong airflow level; when the set temperature + 5℃ < the temperature on the left side of the human body < the set temperature + 10℃, the airflow level of the fresh air fan generating the left airflow wall is set to the medium airflow level; when the temperature on the left side of the human body is ≤ the set temperature + 5℃, the airflow level of the fresh air fan generating the left airflow wall is set to the low airflow level. Then, determine the temperature on the right side, front side, and back side of the human body separately, and control the corresponding airflow level of the fresh air fans.
