[0022] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0025] Figure 3 This is a schematic flowchart of the control method for a kitchen air conditioner according to the present invention.
[0026] Referring to the accompanying drawings, the reference numerals in the embodiments of the present invention are as follows:
[0027] 102 - Acquisition unit; 104 - Control unit. Detailed Implementation
[0028] 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.
[0029] According to an embodiment of the present invention, a control method for an air conditioner is provided, wherein the air conditioner is a kitchen air conditioner; the air conditioner includes an indoor fan, an air guide plate, and a compressor. The kitchen air conditioner is equipped with an infrared sensor or a millimeter-wave radar sensor for detecting the presence of a user in the kitchen and obtaining the distance between the user and the stove. An oil fume detection device and an oil temperature detection device are installed on the range hood in the kitchen; the oil fume detection device is used to collect the oil fume concentration, and the oil temperature detection device is used to collect the oil temperature in the pan or the surface temperature of the pan. The kitchen air conditioner can receive information such as oil fume concentration and oil temperature sent by the oil fume detection device and the oil temperature detection device.
[0030] like 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 S140.
[0031] In step S110, after detecting the presence of a user in the kitchen, the air conditioner is turned on.
[0032] The kitchen air conditioner only activates when someone is cooking, avoiding ineffective operation when no one is present. It uses millimeter-wave radar or infrared sensors to monitor human activity in the kitchen in real time, triggering the start-up command when a user is detected approaching the stove. This reduces energy consumption, avoids environmental interference from the air conditioner's cold air, and improves economic efficiency.
[0033] In some embodiments, camera image recognition technology can be used to replace radar detection, and AI algorithms can be used to identify the presence of human beings in the kitchen.
[0034] In step S120, the oil temperature and oil fume concentration in the pot on the stove in the kitchen are obtained.
[0035] Oil temperature reflects the risk level of oil splashing, while oil fume concentration reflects air quality, providing data support for subsequent control. Data can be collected in real time through temperature and oil fume concentration sensors on the range hood. This allows for precise identification of different cooking stages, such as "cold oil heating" and "high-temperature stir-frying," thus enabling differentiated safety control.
[0036] In step S130, the user's safe position is determined based on the oil temperature in the pot and the concentration of oil fumes.
[0037] When the oil temperature is high or the oil fume concentration is high, the risk of oil splashing and the hazards of oil fumes increase significantly. Users should be advised to stay away from the stove and a recommended safe location should be provided to reduce the probability of hot oil splashing injuries.
[0038] In some embodiments, the determination of a safe location also takes into account the size of the stove flame, forming a multi-parameter fusion distance determination model. The size of the stove flame can be obtained through image recognition.
[0039] In some embodiments, step S130, the specific process of determining the user's safe position based on the oil temperature in the pot and the oil fume concentration, includes: judging the magnitude of the oil temperature in the pot and the magnitude of the oil fume concentration; if the oil temperature in the pot is less than a preset oil temperature threshold and the oil fume concentration is less than a preset oil fume concentration threshold, then the user's safe position is determined to be a preset first position; if the oil temperature in the pot is greater than or equal to the preset oil temperature threshold or the oil fume concentration is greater than or equal to the preset oil fume concentration threshold, then the user's safe position is determined to be a preset second position; wherein, the distance between the preset first position and the stove is less than the distance between the preset second position and the stove.
[0040] Oil temperature and oil fume concentration are core indicators of cooking safety. When the oil temperature exceeds 200℃, the probability of hot oil splattering increases dramatically, and the oil fume concentration exceeds the standard (e.g., >10mg / m³). 3 It can harm the respiratory system. By monitoring both simultaneously, a more comprehensive assessment of the risk level of the cooking environment can be made, avoiding misjudgments based on a single parameter. The preset oil temperature threshold can be set to 200℃, and the preset oil fume concentration threshold can be set to 10mg / m³. 3 When the oil temperature is <200℃ and the oil fume concentration is <10mg / m³ 3 When the oil is initially heated to cold temperature or during low-temperature cooking, the risk of oil splattering is low, allowing users to operate from the closest possible position to the stove, such as 0.5 meters away, balancing safety and cooking convenience; when the oil temperature is ≥200℃ or the oil fume concentration is ≥10mg / m³ 3 In situations involving high-temperature stir-frying or a sudden increase in oil fumes, the oil splash distance can exceed 1 meter. Users must be forced to retreat to a more distant position, such as 1.2 meters away from the stove. Increasing the safe distance reduces the probability of burns.
[0041] In some embodiments, to improve control precision, multiple oil temperature ranges and multiple oil fume concentration ranges can be set, with different ranges corresponding to different safety positions. The oil fume concentration varies at different oil temperatures. In the initial stage of cold oil heating (oil temperature below 60°C), the oil fume concentration is very low and almost negligible. During medium-temperature heating (oil temperature below the smoke point, such as 150°C-200°C), the oil fume concentration begins to rise but remains at a low level. During high-temperature heating (oil temperature above the smoke point, such as above 200°C), the oil fume concentration increases sharply, especially when the oil temperature approaches or exceeds 250°C, where the oil fume concentration rises significantly. At extreme high temperatures (oil temperature above 300°C), the oil fume concentration reaches its peak, and the grease may begin to carbonize, producing more harmful substances. Specifically, when the oil temperature is <60℃ and the oil fume concentration is V1, the safe position is S1; when the oil temperature is between 60℃ and 150℃ and the oil fume concentration is V2, the safe position is S2; when the oil temperature is between 150℃ and 200℃ and the oil fume concentration is V3, the safe position is S3; and when the oil temperature is >200℃ and the oil fume concentration is V4, the safest position is the largest, S4. Where V1 < V2 < V3 < V4, S1 < S2 < S3 < S4, S1 can be set at a distance of 40cm from the stove, S2 at a distance of 60cm from the stove, S3 at a distance of 80cm from the stove, and S4 at a distance of 100cm from the stove.
[0042] By integrating multiple parameters to improve the accuracy of risk assessment, it can avoid excessive reminders that affect the user experience, and provide effective security protection in high-risk scenarios, thus achieving a balance between security and practicality.
[0043] In step S140, the speed of the internal fan and the operating frequency of the compressor are controlled according to the oil temperature in the pot and the oil fume concentration. At the same time, the air guide angle range of the air guide plate is controlled according to the user's safe position, so that the air conditioner outlet forms an airflow barrier to block oil splashes.
[0044] The internal fan speed and compressor frequency are dynamically adjusted according to oil temperature and oil fume concentration to increase cooling capacity and air volume, which can reduce the ambient temperature around the stove and accelerate the diffusion of oil fumes; the angle of the air guide plate is adjusted according to the safe position to direct the cold air to the area between the user and the stove, forming a physical barrier to block oil splashes, while preventing the wind from blowing out the stove flame, thus improving cooking comfort.
[0045] In some embodiments, step S140, the specific process of controlling the air guide angle range of the air guide plate according to the user's safe position, includes: when the user's safe position is a preset first position, prompting the user to be in the preset first position, and controlling the air guide angle range of the air guide plate to a preset first range so that the air outlet of the air conditioner blows towards the area between the preset first position and the stove; when the user's safe position is a preset second position, prompting the user to be in the preset second position, and controlling the air guide angle range of the air guide plate to a preset second range so that the air outlet of the air conditioner blows towards the area between the preset second position and the stove; wherein, the upper limit of the preset first range is less than the lower limit of the preset second range.
[0046] If the system detects that the user has not moved to a safe location as prompted, it will issue an alarm signal and continue for 3 to 5 seconds. After the alarm ends, if the user still has not moved to a safe location, the air conditioner will send a control command to the stove to turn off the flame on the stove.
[0047] To create an airflow barrier that prevents oil splashing, when the user is in the preset first position, the angle of the air guide is controlled within a preset range, such as 10° to 30°. This directs the cool air towards the area between the user and the stove, preventing the flame from being extinguished and creating a slight airflow barrier in front of the user to block a small amount of oil splashing. When the user is in the preset second position, a high-risk scenario with higher oil temperatures or excessive oil fume concentration, the angle of the air guide is controlled within a preset range, such as 40° to 70°. This increases the airflow coverage area, creating a strong airflow barrier. Simultaneously, as the wind speed increases, a negative pressure zone is generated near the stove, accelerating the extraction of oil fumes and blocking oil splashing.
[0048] In some embodiments, to improve control accuracy, multiple safety positions can be set, with different safety positions corresponding to different airflow angle ranges. Specifically, when the safety position is S1, the airflow angle range is θ1 to θ2; when the safety position is S2, the airflow angle range is θ3 to θ4; when the safety position is S3, the airflow angle range is θ4 to θ5; and when the safety position is S4, the airflow angle range is θ5 to θ6, where θ1 < θ2 < θ3 < θ4 < θ5 < θ6. θ1 can be set to 15°, θ2 to 30°, θ3 to 45°, θ4 to 60°, θ5 to 75°, and θ6 to 90°.
[0049] In some embodiments, step S140, which involves controlling the rotation speed of the internal fan and the operating frequency of the compressor based on the oil temperature and the oil fume concentration in the pot, includes: determining the magnitude of the oil temperature and the magnitude of the oil fume concentration in the pot; if the oil temperature in the pot is less than a preset oil temperature threshold and the oil fume concentration is less than a preset oil fume concentration threshold, then controlling the rotation speed of the internal fan to a preset first rotation speed and the operating frequency of the compressor to a preset first frequency; if the oil temperature in the pot is greater than or equal to the preset oil temperature threshold or the oil fume concentration is greater than or equal to the preset oil fume concentration threshold, then controlling the rotation speed of the internal fan to a preset second rotation speed and the operating frequency of the compressor to a preset second frequency; wherein, the preset first rotation speed is less than the preset second rotation speed, and the preset first frequency is less than the preset second frequency.
[0050] Specifically, when the oil temperature is <200℃ and the oil fume concentration is <10mg / m³ 3 At this time, the cooking heat load and oil fume pollution are relatively low, and high-intensity cooling and ventilation are not required. In this situation, controlling the internal fan to a preset first speed P1 (e.g., 500 rpm) and the compressor to a preset first frequency F1 (e.g., 50 Hz) can maintain basic comfort in the kitchen while reducing power consumption. When the oil temperature is ≥200℃ or the oil fume concentration is ≥10mg / m³... 3 At this time, the cooking heat load increases dramatically, significantly increasing the risk of oil splattering and the hazards of cooking fumes. The internal fan then increases to the preset second speed P2 = 1500 rpm, and the compressor increases to the preset second frequency F2 = 120 Hz, increasing the cooling capacity. This, combined with the increased airflow and the angle of the air guide plate, creates a negative pressure zone, accelerating the extraction of cooking fumes.
[0051] In some embodiments, to improve control accuracy, multiple oil temperature ranges and multiple oil fume concentration ranges can be set, with different ranges corresponding to different rotation speeds and frequencies. Specifically, when the oil temperature is <60℃ and the oil fume concentration is V1, the internal fan speed is 750 rpm and the compressor frequency is 30 Hz; when the oil temperature is between 60℃ and 150℃ and the oil fume concentration is V2, the internal fan speed is 1050 rpm and the compressor frequency is 50 Hz; when the oil temperature is between 150℃ and 200℃ and the oil fume concentration is V3, the internal fan speed is 1200 rpm and the compressor frequency is 70 Hz; and when the oil temperature is >200℃ and the oil fume concentration is V4, the internal fan speed is 1300 rpm and the compressor frequency is 90 Hz.
[0052] By controlling the internal fan speed and compressor operating frequency based on the oil temperature and oil fume concentration in the pot, when the oil temperature is below the preset threshold and the oil fume concentration is low, it operates at a lower preset first speed and frequency, which can meet basic comfort needs, reduce energy consumption, reduce noise, and extend the equipment life. When the oil temperature is above the preset threshold or the oil fume concentration exceeds the standard, it increases to a higher preset second speed and frequency, which quickly reduces the temperature around the stove, increases the air volume to form a negative pressure zone, accelerates the dispersion of oil fumes, and enhances the effect of blocking oil splashes. This achieves dynamic adjustment of equipment output according to the risk level of the cooking environment, ensuring cooking safety and comfort.
[0053] In some embodiments, the air conditioner is capable of sending control commands to the stove. The method further includes: when the oil temperature in the pot is greater than a preset maximum oil temperature and no user activity is detected, controlling the air conditioner to send a control command to the stove to turn off the flame.
[0054] When the oil temperature in the pan exceeds the preset maximum oil temperature (e.g., 250℃) and there is no user activity in the kitchen, a "dry burning" scenario may occur. For example, if the food is burnt and the user leaves the kitchen, the probability of a fire is high. Therefore, when the oil temperature in the pan is detected to be >250℃ and no user activity is detected, the air conditioner sends a control command to the stove to turn off the flame and prevent a safety accident. Specifically, if no footprints of human activity are detected for 120 consecutive seconds or the distance of human movement is less than 50cm, it is considered that no user activity has been detected.
[0055] By controlling the air conditioner to send a shut-off command to the stove, the risk of fire and gas leak caused by excessive oil temperature when the stove is unattended can be proactively eliminated, protecting life and property safety while reducing gas waste and equipment damage.
[0056] In some embodiments, the method further includes: after turning on the air conditioner, if it is detected that there is no oil in the pot on the stove in the kitchen, then obtaining the surface temperature of the pot; determining the magnitude of the surface temperature of the pot; if the surface temperature of the pot is less than a preset temperature, then reminding the user to be in a preset third position; if the surface temperature of the pot is greater than or equal to the preset temperature, then reminding the user to be in a preset fourth position; wherein the distance between the preset third position and the stove is less than the distance between the preset fourth position and the stove.
[0057] In oil-free cooking scenarios, such as boiling and steaming, while there is no oil splattering or heavy fumes, there is still a risk of burns. For example, when the surface temperature of the pot is ≥100℃, contact with the human body may cause second-degree burns, while at a temperature <60℃, there is virtually no risk of burns. The preset temperature can be set to 60℃. When the pot's surface temperature is <60℃, the user is reminded to move to a preset third position, such as 0.5m from the stovetop; when the pot's surface temperature is ≥60℃, the user is reminded to move to a preset fourth position, such as 0.8m from the stovetop, to prevent steam burns. By detecting the pot's surface temperature when oil-free, the system reminds the user to move to different safe positions, ensuring ease of operation at low temperatures and preventing steam burns at high temperatures, achieving precise safety protection in oil-free cooking scenarios.
[0058] In some embodiments, the system can remind the user of their location based on the size of the stove flame. Specifically, when the user turns on the gas and there is no cooking oil in the pot, the system will remind the user that they are 0.5m away from the gas stove when the flame is low or medium-low, and will remind the user that they are 0.8m away from the gas stove when the flame is high.
[0059] Figure 3 This is a schematic flowchart of the kitchen air conditioner control method of the present invention, as shown below. Figure 3 As shown, the method includes:
[0060] Step 1: The air conditioning system detects whether someone is cooking in the kitchen every Δt seconds. When someone is detected cooking in the kitchen, the air conditioning is turned on.
[0061] Step 2: The air conditioner checks if there is oil in the pot on the stove. If there is no oil, proceed to Step 3; if there is oil, proceed to Step 4.
[0062] Step 3: Check the flame level of the stove. If it is a medium-low flame, remind the user to keep a distance of S1 from the stove; if it is a high flame, remind the user to keep a distance of S2 from the stove, where S1 < S2.
[0063] Step 4: Determine the temperature of the oil in the pot.
[0064] If the oil temperature is <60℃, and the detected oil fume concentration is V1, the air conditioner will prompt the user to be positioned away from the gas stove S3, adjust the indoor unit's air guide plate rotation angle θ, and make it move back and forth slowly within θ1 < θ < θ2. The cross-flow fan blades will rotate at a speed of P1, and the compressor will run at a lower frequency F1.
[0065] If 60℃≤oil temperature<150℃, and the detected oil fume concentration is V2, the air conditioner will prompt the user to be at a position away from the gas stove S4, adjust the indoor unit's air guide plate rotation angle θ, so that it moves back and forth slowly within θ3<θ<θ4, the cross-flow fan blades rotate at speed P2, and the compressor runs at a lower frequency F2.
[0066] If 120℃≤oil temperature<200℃, and the detected oil fume concentration is V3, the air conditioner will prompt the user to be at a position away from the gas stove S5, adjust the indoor unit's air guide plate rotation angle θ, so that it moves back and forth slowly within θ4<θ<θ5, the cross-flow fan blades rotate at speed P3, and the compressor runs at a lower frequency F3.
[0067] If the oil temperature is >200℃, and the detected oil fume concentration is V4, the air conditioner will prompt the user to move to a position S6 away from the gas stove, adjust the indoor unit's air guide vane rotation angle θ so that it moves slowly back and forth within θ5 < θ < θ6, the cross-flow fan blades rotate at speed P4, and the compressor runs at a lower frequency F4. S3 < S4 < S5 < S6, θ1 < θ2 < θ3 < θ4 < θ5 < θ6, P1 < P2 < P3 < P4, F1 < F2 < F3 < F4.
[0068] If the oil temperature exceeds the temperature threshold and the air conditioner's infrared radar system does not detect any user activity near the stove, the air conditioner system will issue a command to turn off the flame on the stove and simultaneously issue an alarm signal to remind the user.
[0069] The technical solution of this embodiment activates the air conditioner upon detecting a user in the kitchen. It determines the user's safe position based on the oil temperature and fume concentration in the pan on the stove, and controls the internal fan speed, compressor operating frequency, and air deflector angle to create an airflow barrier that prevents oil splashing. By actively determining the user's safe position in the kitchen and controlling the air conditioner's internal fan, air deflector, and compressor, an airflow barrier is formed to prevent oil splashing, thus improving comfort while ensuring cooking safety.
[0070] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. The air conditioner is a kitchen air conditioner; the air conditioner includes an indoor fan, an air guide plate, and a compressor. The kitchen air conditioner is equipped with an infrared sensor or a millimeter-wave radar sensor for detecting the presence of a user in the kitchen and obtaining the distance between the user and the stove. An oil fume detection device and an oil temperature detection device are installed on the range hood in the kitchen. The oil fume detection device is used to collect the oil fume concentration, and the oil temperature detection device is used to collect the oil temperature in the pan or the surface temperature of the pan. The kitchen air conditioner can receive information such as oil fume concentration and oil temperature sent by the oil fume detection device and the oil temperature detection device.
[0071] See Figure 2 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.
[0072] Control unit 104 is configured to turn on the air conditioner after detecting the presence of a user in the kitchen. The specific functions and processing of control unit 104 are described in step S110.
[0073] The kitchen air conditioner only activates when someone is cooking, avoiding ineffective operation when no one is present. It uses millimeter-wave radar or infrared sensors to monitor human activity in the kitchen in real time, triggering the start-up command when a user is detected approaching the stove. This reduces energy consumption, avoids environmental interference from the air conditioner's cold air, and improves economic efficiency.
[0074] In some embodiments, camera image recognition technology can be used to replace radar detection, and AI algorithms can be used to identify the presence of human beings in the kitchen.
[0075] The acquisition unit 102 is configured to acquire the oil temperature and oil fume concentration in the pot on the stove in the kitchen. The specific functions and processing of the acquisition unit 102 are described in step S120.
[0076] Oil temperature reflects the risk level of oil splashing, while oil fume concentration reflects air quality, providing data support for subsequent control. Data can be collected in real time through temperature and oil fume concentration sensors on the range hood. This allows for precise identification of different cooking stages, such as "cold oil heating" and "high-temperature stir-frying," thus enabling differentiated safety control.
[0077] The control unit 104 is also configured to determine the user's safe position based on the oil temperature and the concentration of oil fumes in the pot. The specific functions and processing of the control unit 104 are described in step S130.
[0078] When the oil temperature is high or the oil fume concentration is high, the risk of oil splashing and the hazards of oil fumes increase significantly. Users should be advised to stay away from the stove and a recommended safe location should be provided to reduce the probability of hot oil splashing injuries.
[0079] In some embodiments, the determination of a safe location also takes into account the size of the stove flame, forming a multi-parameter fusion distance determination model. The size of the stove flame can be obtained through image recognition.
[0080] In some embodiments, the control unit 104 determines the user's safe position based on the oil temperature in the pot and the oil fume concentration, including: judging the magnitude of the oil temperature in the pot and the magnitude of the oil fume concentration; if the oil temperature in the pot is less than a preset oil temperature threshold and the oil fume concentration is less than a preset oil fume concentration threshold, then the user's safe position is determined to be a preset first position; if the oil temperature in the pot is greater than or equal to the preset oil temperature threshold or the oil fume concentration is greater than or equal to the preset oil fume concentration threshold, then the user's safe position is determined to be a preset second position; wherein, the distance between the preset first position and the stove is less than the distance between the preset second position and the stove.
[0081] Oil temperature and oil fume concentration are core indicators of cooking safety. When the oil temperature exceeds 200℃, the probability of hot oil splattering increases dramatically, and the oil fume concentration exceeds the standard (e.g., >10mg / m³). 3 It can harm the respiratory system. By monitoring both simultaneously, a more comprehensive assessment of the risk level of the cooking environment can be made, avoiding misjudgments based on a single parameter. The preset oil temperature threshold can be set to 200℃, and the preset oil fume concentration threshold can be set to 10mg / m³. 3 When the oil temperature is <200℃ and the oil fume concentration is <10mg / m³ 3 When the oil is initially heated to cold temperature or during low-temperature cooking, the risk of oil splattering is low, allowing users to operate from the closest possible position to the stove, such as 0.5 meters away, balancing safety and cooking convenience; when the oil temperature is ≥200℃ or the oil fume concentration is ≥10mg / m³ 3 In situations involving high-temperature stir-frying or a sudden increase in oil fumes, the oil splash distance can exceed 1 meter. Users must be forced to retreat to a more distant position, such as 1.2 meters away from the stove. Increasing the safe distance reduces the probability of burns.
[0082] In some embodiments, to improve control precision, multiple oil temperature ranges and multiple oil fume concentration ranges can be set, with different ranges corresponding to different safety positions. The oil fume concentration varies at different oil temperatures. In the initial stage of cold oil heating (oil temperature below 60°C), the oil fume concentration is very low and almost negligible. During medium-temperature heating (oil temperature below the smoke point, such as 150°C-200°C), the oil fume concentration begins to rise but remains at a low level. During high-temperature heating (oil temperature above the smoke point, such as above 200°C), the oil fume concentration increases sharply, especially when the oil temperature approaches or exceeds 250°C, where the oil fume concentration rises significantly. At extreme high temperatures (oil temperature above 300°C), the oil fume concentration reaches its peak, and the grease may begin to carbonize, producing more harmful substances. Specifically, when the oil temperature is <60℃ and the oil fume concentration is V1, the safe position is S1; when the oil temperature is between 60℃ and 150℃ and the oil fume concentration is V2, the safe position is S2; when the oil temperature is between 150℃ and 200℃ and the oil fume concentration is V3, the safe position is S3; and when the oil temperature is >200℃ and the oil fume concentration is V4, the safest position is the largest, S4. Where V1 < V2 < V3 < V4, S1 < S2 < S3 < S4, S1 can be set at a distance of 40cm from the stove, S2 at a distance of 60cm from the stove, S3 at a distance of 80cm from the stove, and S4 at a distance of 100cm from the stove.
[0083] By integrating multiple parameters to improve the accuracy of risk assessment, it can avoid excessive reminders that affect the user experience, and provide effective security protection in high-risk scenarios, thus achieving a balance between security and practicality.
[0084] The control unit 104 is also configured to control the speed of the internal fan and the operating frequency of the compressor according to the oil temperature in the pot and the oil fume concentration, and simultaneously control the air guide angle range of the air guide plate according to the user's safe position, so that the air conditioner outlet forms an airflow barrier to block oil splashes. For the specific functions and processing of this control unit 104, please refer to step S140.
[0085] The internal fan speed and compressor frequency are dynamically adjusted according to oil temperature and oil fume concentration to increase cooling capacity and air volume, which can reduce the ambient temperature around the stove and accelerate the diffusion of oil fumes; the angle of the air guide plate is adjusted according to the safe position to direct the cold air to the area between the user and the stove, forming a physical barrier to block oil splashes, while preventing the wind from blowing out the stove flame, thus improving cooking comfort.
[0086] In some embodiments, the control unit 104 controls the air guide angle range of the air deflector according to the user's safe position, including: when the user's safe position is a preset first position, prompting the user to be in the preset first position, and controlling the air guide angle range of the air deflector to a preset first range so that the air outlet of the air conditioner blows towards the area between the preset first position and the stove; when the user's safe position is a preset second position, prompting the user to be in the preset second position, and controlling the air guide angle range of the air deflector to a preset second range so that the air outlet of the air conditioner blows towards the area between the preset second position and the stove; wherein, the upper limit of the preset first range is less than the lower limit of the preset second range.
[0087] If the system detects that the user has not moved to a safe location as prompted, it will issue an alarm signal and continue for 3 to 5 seconds. After the alarm ends, if the user still has not moved to a safe location, the air conditioner will send a control command to the stove to turn off the flame on the stove.
[0088] To create an airflow barrier that prevents oil splashing, when the user is in the preset first position, the angle of the air guide is controlled within a preset range, such as 10° to 30°. This directs the cool air towards the area between the user and the stove, preventing the flame from being extinguished and creating a slight airflow barrier in front of the user to block a small amount of oil splashing. When the user is in the preset second position, a high-risk scenario with higher oil temperatures or excessive oil fume concentration, the angle of the air guide is controlled within a preset range, such as 40° to 70°. This increases the airflow coverage area, creating a strong airflow barrier. Simultaneously, as the wind speed increases, a negative pressure zone is generated near the stove, accelerating the extraction of oil fumes and blocking oil splashing.
[0089] In some embodiments, to improve control accuracy, multiple safety positions can be set, with different safety positions corresponding to different airflow angle ranges. Specifically, when the safety position is S1, the airflow angle range is θ1 to θ2; when the safety position is S2, the airflow angle range is θ3 to θ4; when the safety position is S3, the airflow angle range is θ4 to θ5; and when the safety position is S4, the airflow angle range is θ5 to θ6, where θ1 < θ2 < θ3 < θ4 < θ5 < θ6. θ1 can be set to 15°, θ2 to 30°, θ3 to 45°, θ4 to 60°, θ5 to 75°, and θ6 to 90°.
[0090] In some embodiments, the control unit 104 controls the rotation speed of the internal fan and the operating frequency of the compressor based on the oil temperature and the oil fume concentration in the pot, including: determining the magnitude of the oil temperature and the magnitude of the oil fume concentration in the pot; if the oil temperature in the pot is less than a preset oil temperature threshold and the oil fume concentration is less than a preset oil fume concentration threshold, then controlling the rotation speed of the internal fan to a preset first rotation speed and the operating frequency of the compressor to a preset first frequency; if the oil temperature in the pot is greater than or equal to the preset oil temperature threshold or the oil fume concentration is greater than or equal to the preset oil fume concentration threshold, then controlling the rotation speed of the internal fan to a preset second rotation speed and the operating frequency of the compressor to a preset second frequency; wherein, the preset first rotation speed is less than the preset second rotation speed and the preset first frequency is less than the preset second frequency.
[0091] Specifically, when the oil temperature is <200℃ and the oil fume concentration is <10mg / m³ 3 At this time, the cooking heat load and oil fume pollution are relatively low, and high-intensity cooling and ventilation are not required. In this situation, controlling the internal fan to a preset first speed P1 (e.g., 500 rpm) and the compressor to a preset first frequency F1 (e.g., 50 Hz) can maintain basic comfort in the kitchen while reducing power consumption. When the oil temperature is ≥200℃ or the oil fume concentration is ≥10mg / m³... 3 At this time, the cooking heat load increases dramatically, significantly increasing the risk of oil splattering and the hazards of cooking fumes. The internal fan then increases to the preset second speed P2 = 1500 rpm, and the compressor increases to the preset second frequency F2 = 120 Hz, increasing the cooling capacity. This, combined with the increased airflow and the angle of the air guide plate, creates a negative pressure zone, accelerating the extraction of cooking fumes.
[0092] In some embodiments, to improve control accuracy, multiple oil temperature ranges and multiple oil fume concentration ranges can be set, with different ranges corresponding to different rotation speeds and frequencies. Specifically, when the oil temperature is <60℃ and the oil fume concentration is V1, the internal fan speed is 750 rpm and the compressor frequency is 30 Hz; when the oil temperature is between 60℃ and 150℃ and the oil fume concentration is V2, the internal fan speed is 1050 rpm and the compressor frequency is 50 Hz; when the oil temperature is between 150℃ and 200℃ and the oil fume concentration is V3, the internal fan speed is 1200 rpm and the compressor frequency is 70 Hz; and when the oil temperature is >200℃ and the oil fume concentration is V4, the internal fan speed is 1300 rpm and the compressor frequency is 90 Hz.
[0093] By controlling the internal fan speed and compressor operating frequency based on the oil temperature and oil fume concentration in the pot, when the oil temperature is below the preset threshold and the oil fume concentration is low, it operates at a lower preset first speed and frequency, which can meet basic comfort needs, reduce energy consumption, reduce noise, and extend the equipment life. When the oil temperature is above the preset threshold or the oil fume concentration exceeds the standard, it increases to a higher preset second speed and frequency, which quickly reduces the temperature around the stove, increases the air volume to form a negative pressure zone, accelerates the dispersion of oil fumes, and enhances the effect of blocking oil splashes. This achieves dynamic adjustment of equipment output according to the risk level of the cooking environment, ensuring cooking safety and comfort.
[0094] In some embodiments, the air conditioner is capable of sending control commands to the stove. Specifically, the control unit 104 is further configured to: when the oil temperature in the pot is greater than a preset maximum oil temperature and no user activity is detected, control the air conditioner to send a control command to the stove to turn off the flame.
[0095] When the oil temperature in the pan exceeds the preset maximum oil temperature (e.g., 250℃) and there is no user activity in the kitchen, a "dry burning" scenario may occur. For example, if the food is burnt and the user leaves the kitchen, the probability of a fire is high. Therefore, when the oil temperature in the pan is detected to be >250℃ and no user activity is detected, the air conditioner sends a control command to the stove to turn off the flame and prevent a safety accident. Specifically, if no footprints of human activity are detected for 120 consecutive seconds or the distance of human movement is less than 50cm, it is considered that no user activity has been detected.
[0096] By controlling the air conditioner to send a shut-off command to the stove, the risk of fire and gas leak caused by excessive oil temperature when the stove is unattended can be proactively eliminated, protecting life and property safety while reducing gas waste and equipment damage.
[0097] In some embodiments, the control unit 104 is further configured to: after the air conditioner is turned on, if it is detected that there is no oil in the pot on the stove in the kitchen, obtain the surface temperature of the pot; determine the magnitude of the surface temperature of the pot; if the surface temperature of the pot is less than a preset temperature, remind the user to be in a preset third position; if the surface temperature of the pot is greater than or equal to the preset temperature, remind the user to be in a preset fourth position; wherein the distance between the preset third position and the stove is less than the distance between the preset fourth position and the stove.
[0098] In oil-free cooking scenarios, such as boiling and steaming, while there is no oil splattering or heavy fumes, there is still a risk of burns. For example, when the surface temperature of the pot is ≥100℃, contact with the human body may cause second-degree burns, while at a temperature <60℃, there is virtually no risk of burns. The preset temperature can be set to 60℃. When the pot's surface temperature is <60℃, the user is reminded to move to a preset third position, such as 0.5m from the stovetop; when the pot's surface temperature is ≥60℃, the user is reminded to move to a preset fourth position, such as 0.8m from the stovetop, to prevent steam burns. By detecting the pot's surface temperature when oil-free, the system reminds the user to move to different safe positions, ensuring ease of operation at low temperatures and preventing steam burns at high temperatures, achieving precise safety protection in oil-free cooking scenarios.
[0099] In some embodiments, the system can remind the user of their location based on the size of the stove flame. Specifically, when the user turns on the gas and there is no cooking oil in the pot, the system will remind the user that they are 0.5m away from the gas stove when the flame is low or medium-low, and will remind the user that they are 0.8m away from the gas stove when the flame is high.
[0100] Figure 3 This is a schematic flowchart of the kitchen air conditioner control method of the present invention, as shown below. Figure 3 As shown, the method includes:
[0101] Step 1: The air conditioning system detects whether someone is cooking in the kitchen every Δt seconds. When someone is detected cooking in the kitchen, the air conditioning is turned on.
[0102] Step 2: The air conditioner checks if there is oil in the pot on the stove. If there is no oil, proceed to Step 3; if there is oil, proceed to Step 4.
[0103] Step 3: Check the flame level of the stove. If it is a medium-low flame, remind the user to keep a distance of S1 from the stove; if it is a high flame, remind the user to keep a distance of S2 from the stove, where S1 < S2.
[0104] Step 4: Determine the temperature of the oil in the pot.
[0105] If the oil temperature is <60℃, and the detected oil fume concentration is V1, the air conditioner will prompt the user to be positioned away from the gas stove S3, adjust the indoor unit's air guide plate rotation angle θ, and make it move back and forth slowly within θ1 < θ < θ2. The cross-flow fan blades will rotate at a speed of P1, and the compressor will run at a lower frequency F1.
[0106] If 60℃≤oil temperature<150℃, and the detected oil fume concentration is V2, the air conditioner will prompt the user to be at a position away from the gas stove S4, adjust the indoor unit's air guide plate rotation angle θ, so that it moves back and forth slowly within θ3<θ<θ4, the cross-flow fan blades rotate at speed P2, and the compressor runs at a lower frequency F2.
[0107] If 120℃≤oil temperature<200℃, and the detected oil fume concentration is V3, the air conditioner will prompt the user to be at a position away from the gas stove S5, adjust the indoor unit's air guide plate rotation angle θ, so that it moves back and forth slowly within θ4<θ<θ5, the cross-flow fan blades rotate at speed P3, and the compressor runs at a lower frequency F3.
[0108] If the oil temperature is >200℃, and the detected oil fume concentration is V4, the air conditioner will prompt the user to move to a position S6 away from the gas stove, adjust the indoor unit's air guide vane rotation angle θ so that it moves slowly back and forth within θ5 < θ < θ6, the cross-flow fan blades rotate at speed P4, and the compressor runs at a lower frequency F4. S3 < S4 < S5 < S6, θ1 < θ2 < θ3 < θ4 < θ5 < θ6, P1 < P2 < P3 < P4, F1 < F2 < F3 < F4.
[0109] If the oil temperature exceeds the temperature threshold and the air conditioner's infrared radar system does not detect any user activity near the stove, the air conditioner system will issue a command to turn off the flame on the stove and simultaneously issue an alarm signal to remind the user.
