Description

Technical Field

[0001] This invention relates to the field of kitchen air management technology, and in particular to a kitchen air supply method, air supply system, control device, and electronic equipment. Background Technology

[0002] Kitchens commonly use range hoods to expel cooking fumes. These fumes mix with a large amount of air during exhaust. To prevent the fumes from spreading to other living areas or to avoid temperature exchange with the outside environment, doors and windows are usually closed during cooking. The exhaust from the range hood creates negative pressure in the kitchen, causing a replenishment effect of air from the outside environment into the kitchen.

[0003] In related technologies, when the air supply flow to the kitchen is large, crosswinds are easily formed. These crosswinds disperse cooking fumes, which directly enter the range hood, thus affecting its smoke extraction efficiency. When kitchen doors and windows are closed or the air supply flow is low, outside air enters the kitchen through narrow gaps in the doors and windows. On the one hand, the airflow passing through these gaps creates a whistling sound, causing the doors and windows to vibrate and slam; on the other hand, the airflow encounters significant flow resistance through these gaps, increasing the back pressure that the range hood needs to withstand during operation, leading to a deterioration in its performance and a noticeable escape of smoke. Managing the air supply process in the kitchen while the range hood is operating is also difficult. Summary of the Invention

[0074] In related technologies, when the air supply flow to the kitchen is large, crosswinds are easily formed. These crosswinds disperse cooking fumes, which directly enter the range hood, thus affecting its smoke extraction efficiency. When kitchen doors and windows are closed or the air supply flow is low, outside air enters the kitchen through narrow gaps in the doors and windows. On the one hand, the airflow passing through these gaps creates a whistling sound, causing the doors and windows to vibrate and slam; on the other hand, the airflow encounters significant flow resistance through these gaps, increasing the back pressure that the range hood needs to withstand during operation, leading to a deterioration in its performance and a noticeable escape of smoke. Managing the air supply process in the kitchen while the range hood is operating is also difficult.

[0075] Please refer to the kitchen air supply method provided by the first aspect embodiment of the present invention. Figure 1 ,include:

[0076] S110. Obtain the concentration of cooking fumes in the indoor air and the exhaust flow rate of the cooking fume exhaust device.

[0077] Understandably, the fume extraction devices include range hoods, fume purifiers, etc.

[0078] The concentration of cooking fumes in indoor air can be obtained through, but is not limited to, the following methods:

[0079] Firstly, the concentration of cooking fumes in the kitchen can be detected using a smoke sensor, for example, by detecting the light transmittance of the air to determine the concentration of cooking fumes in the air.

[0080] When using a smoke sensor to detect the concentration of cooking fumes in a kitchen, it is necessary to avoid the sticky substances in the fumes interfering with the sensitivity of the optical devices.

[0081] Secondly, the concentration of cooking fumes in the kitchen is detected by an organic compound sensor, also known as a VOC (volatile organic compounds) sensor. This sensor detects the concentration of cooking fumes in the air by measuring the content of organic compound molecules in the air.

[0082] When using an organic compound sensor to detect the concentration of cooking fumes, the concentration of cooking fumes in the air can be reflected by the content of organic compound molecules in the air, resulting in more accurate detection results.

[0083] When measuring the concentration of cooking fumes in indoor air, it's necessary to avoid the normal upward path of the fumes, specifically the area between the stove and the exhaust inlet of the fume extraction device. As cooking fumes diffuse into the rest of the kitchen, they form ambient air, and the concentration of cooking fumes in this ambient air reflects the escape and diffusion of these fumes.

[0084] Obtain the exhaust airflow of the fume extraction device, including but not limited to the following methods:

[0085] Firstly, an airflow detection device, such as a flow sensor, can be installed in the exhaust duct of the fume extraction device to directly read the exhaust flow rate.

[0086] Secondly, read the operating parameters of the fume exhaust device, such as its speed and rotation speed, and calculate the exhaust flow rate in combination with other structural parameters.

[0087] Third, read the operating parameters of the fume exhaust device, such as the operating current and voltage, and calculate the exhaust flow rate in combination with the specifications and model of the drive device.

[0088] When obtaining indoor oil fume concentration and exhaust flow rate of oil fume exhaust devices, one method or a combination of methods can be used to improve the accuracy of the data.

[0089] S120. Determine the makeup air flow rate based on the oil fume concentration and exhaust flow rate.

[0090] Understandably, when the fume extraction device is working, the air pressure in the kitchen decreases, increasing the back pressure that the device needs to withstand. This reduces the efficiency of fume extraction, leading to smoke leakage. The diffused fumes increase the concentration of fumes in the indoor air, indirectly reflecting the malfunction of the fume extraction device.

[0091] The higher the concentration of cooking fumes in the indoor air, the worse the working condition of the fume exhaust device, and the greater the necessity and demand for supplemental air.

[0092] The lower the concentration of cooking fumes in the indoor air, the better the working condition of the fume exhaust device, the less necessary the supplementary air supply is, and the lower the demand for supplementary air.

[0093] At the same time, the supply air flow rate is positively correlated with the exhaust air flow rate. The larger the exhaust air flow rate, the more air needs to be supplied to the kitchen, and the smaller the exhaust air flow rate, the less air needs to be supplied to the kitchen.

[0094] The make-up air flow rate is positively correlated with both the exhaust air flow rate and the concentration of cooking fumes. When the make-up air strategy is formulated based on the environmental factors of indoor air, the efficiency of cooking fume removal is relatively high.

[0095] S130. Based on the make-up air flow rate, output control commands to the make-up air component for adjusting the flow rate.

[0096] Understandably, after determining the makeup air flow rate, outdoor air is drawn into the room through the makeup air assembly to achieve indoor air balance. Once activated, the makeup air assembly receives control commands to adjust the makeup air flow rate and then introduces outdoor air into the room according to that flow rate.

[0097] When the indoor fume concentration is high, a larger air supply flow rate is needed to improve the indoor air circulation efficiency and promptly remove the diffused fumes from the indoor air.

[0098] When the indoor fume concentration is low, the make-up air flow rate is small, which helps save energy.

[0099] The kitchen air supply method provided in this invention is positively correlated with the oil fume concentration. Different air supply coefficients can be determined according to the oil fume concentration. The air supply coefficients can be divided into multiple levels according to the different oil fume concentrations, and then the air supply flow rate is determined according to the different levels of air supply coefficients.

[0100] According to one embodiment of the present invention, determining the makeup air flow rate based on the oil fume concentration and the exhaust air flow rate includes:

[0101] S121. Determine the make-up air coefficient based on the oil fume concentration.

[0102] It is understandable that the concentration of indoor cooking fumes can indirectly reflect the working condition of the fume exhaust device; when the concentration of cooking fumes is high, the need for supplemental air is greater.

[0103] The following methods can be used to determine the makeup air coefficient:

[0104] Firstly, the make-up air coefficient is directly proportional to the oil fume concentration. As the oil fume concentration changes, the make-up air coefficient changes synchronously, and there is a direct proportional function relationship between the oil fume concentration and the make-up air coefficient.

[0105] Secondly, the oil fume concentration is divided into different levels, each level covering a certain concentration range. Under the same level, the air supply coefficient remains unchanged, and the air supply component is divided into multiple different air supply levels.

[0106] When determining the make-up air coefficient, in addition to the two methods mentioned above, you can also fit the experimental data to obtain a make-up air coefficient that is more in line with reality.

[0107] S122. Determine the make-up air flow rate based on the make-up air coefficient and the exhaust air flow rate.

[0108] It is understandable that the intake air flow rate and the exhaust air flow rate are positively correlated. The larger the exhaust air flow rate, the more air needs to be supplied to the kitchen, and the smaller the exhaust air flow rate, the less air needs to be supplied to the kitchen.

[0109] In this embodiment of the invention, when determining the make-up air flow rate, the make-up air coefficient is combined with the exhaust air flow rate, and the two are used together to determine the magnitude of the exhaust air flow rate.

[0110] When the make-up air coefficient is proportional to the indoor oil fume concentration, the make-up air coefficient increases as the oil fume concentration increases, and the make-up air flow rate increases accordingly.

[0111] When the make-up air coefficient is divided into different levels according to the indoor oil fume concentration, the make-up air flow rate is also divided into multiple levels. The make-up air component includes multiple gears, each corresponding to a different make-up air level.

[0112] According to one embodiment of the present invention, determining the makeup air flow rate based on the makeup air coefficient and the exhaust air flow rate includes:

[0113] S1221. Determine the make-up air flow rate based on the product of the make-up air coefficient and the exhaust air flow rate.

[0114] It is understandable that the make-up air flow rate is positively correlated with both the exhaust air flow rate and the concentration of cooking fumes. When the make-up air strategy is formulated based on the environmental factors of indoor air, the efficiency of cooking fume removal is higher and the effect of indoor smoke extraction is better.

[0115] Once the make-up air coefficient is determined based on the oil fume concentration, the impact of the indoor oil fume concentration on the make-up air flow rate is determined. By multiplying the make-up air coefficient by the exhaust air flow rate, the magnitude of the make-up air flow rate can be calculated.

[0116] The make-up air flow rate is equal to the product of the make-up air coefficient and the exhaust air flow rate. It takes into account both the influence of indoor oil fume concentration on the make-up air flow rate and the influence of exhaust air flow rate on the make-up air flow rate.

[0117] When the concentration of cooking fumes is high, the fume extraction efficiency is low, and the demand for indoor air supply is greater. By using a larger air supply coefficient, rapid indoor air circulation can be achieved, improving fume extraction efficiency and enhancing indoor air quality.

[0118] When the exhaust air volume is large, the indoor air is discharged more efficiently, and the indoor air pressure drops more quickly. This increases the back pressure that the fume extraction device needs to withstand, reducing the fume extraction efficiency and increasing the demand for supplementary air. Conversely, when the exhaust air volume is large, the supplementary air volume increases simultaneously, which helps maintain indoor air pressure balance.

[0119] According to one embodiment of the present invention, determining the make-up air coefficient based on the oil fume concentration includes:

[0120] S1211. When the oil fume concentration is greater than the target concentration threshold, determine the first make-up air coefficient.

[0121] S1212. Determine the second make-up air coefficient when the oil fume concentration is not greater than the target concentration threshold.

[0122] Among them, the first make-up air coefficient is greater than the second make-up air coefficient, and the make-up air coefficient is positively correlated with the make-up air flow rate.

[0123] It is understandable that the concentration of indoor cooking fumes can indirectly reflect the working condition of the fume exhaust device; when the concentration of cooking fumes is high, the need for supplemental air is greater.

[0124] In the kitchen air supply method provided in this embodiment of the invention, the air supply coefficient is divided into two different levels according to the indoor oil fume concentration. The air supply coefficients corresponding to different levels are different, which in turn affects the size of the air supply flow.

[0125] When determining the make-up air coefficient, first determine the target concentration threshold of the oil fume, and then determine different make-up air coefficients based on the relationship between the indoor oil fume concentration and the target concentration threshold.

[0126] When the indoor oil fume concentration is greater than the target concentration threshold, the magnitude of the make-up air coefficient is determined as the first make-up air coefficient.

[0127] When the indoor oil fume concentration is not greater than the target concentration threshold, the magnitude of the make-up air coefficient is determined as the second make-up air coefficient.

[0128] When the concentration of cooking fumes is high, the demand for make-up air is greater. Therefore, the first make-up air coefficient is greater than the second make-up air coefficient, and the make-up air coefficient is positively correlated with the make-up air flow rate.

[0129] In the kitchen air supply method provided by this invention, the supply air flow rate is determined by the concentration of cooking fumes in the indoor air and the exhaust flow rate of the fume extraction device. The supply air strategy is determined based on environmental factors, resulting in higher fume extraction efficiency and improved indoor air quality. When starting the exhaust system, the supply air system can be manually activated based on observed fume extraction, or it can be automatically activated based on environmental factors obtained from sensors.

[0130] According to one embodiment of the present invention, before obtaining the concentration of cooking fumes in indoor air and the exhaust flow rate of the cooking fume exhaust device, the method further includes:

[0131] S101, Obtain indoor air pressure.

[0132] S102. When the indoor air pressure reaches the first threshold, output a control command for starting the air supply unit.

[0133] Understandably, indoor air pressure can be detected by either a pressure sensor or a barometer.

[0134] When the difference between indoor air pressure and atmospheric pressure is small, the back pressure resisted by the fume exhaust device is small, the efficiency of fume exhaust is high, and there is no fume escape. At this time, it is not necessary to start the exhaust component.

[0135] When the difference between indoor air pressure and atmospheric pressure is large, the back pressure resisted by the fume extraction device is greater, resulting in lower fume extraction efficiency and fume leakage. By using the air pressure at which smoke leakage occurs as the first threshold, the control device actively activates the air supply component when the indoor air pressure reaches this threshold, making kitchen air supply more intelligent and flexible.

[0136] In the kitchen air supply method provided by this invention, outdoor air is drawn into the room through an air supply component, which can balance the indoor air pressure and ensure efficient exhaust of indoor cooking fumes. When the outdoor temperature is low, the outdoor air will lower the indoor temperature, causing discomfort to occupants and potentially affecting their health.

[0137] According to one embodiment of the present invention, after determining the makeup air flow rate based on the oil fume concentration and the exhaust air flow rate, the method further includes:

[0138] S1201, Obtain indoor and outdoor temperatures.

[0139] S1202. When the difference between the indoor temperature and the outdoor temperature reaches the second threshold, output a control command for heating to the heating component.

[0140] It is understandable that the air supply unit draws outdoor air into the room, and when the outdoor temperature is low, people inside may experience discomfort.

[0141] When obtaining indoor and outdoor temperatures, temperature detection components can be set up both indoors and outdoors to calculate the temperature difference between indoors and outdoors.

[0142] When the temperature difference between indoors and outdoors is small, outdoor air entering the room will not lower the indoor temperature or the temperature drop will be minimal, so there is no need to turn on the heating components.

[0143] When there is a large temperature difference between indoors and outdoors, the entry of cold outdoor air into the room can cause a sharp drop in indoor temperature, affecting the comfort of people indoors. In this case, it is necessary to turn on the heating components.

[0144] In one embodiment, different heating powers can be implemented based on the indoor and outdoor temperature difference, and the controller sends different heating commands to the heating components.

[0145] When there is a large temperature difference between indoors and outdoors, the heating element requires a higher power.

[0146] When the temperature difference between indoors and outdoors is small, the power of the heating element is relatively small.

[0147] In the kitchen air supply method provided by this invention, outdoor air is drawn into the room through an air supply component, which can balance the indoor air pressure and ensure efficient exhaust of indoor cooking fumes. In environments with poor air quality, particulate matter or dust can reduce indoor air quality and even affect the health of people inside.

[0148] According to one embodiment of the present invention, after determining the makeup air flow rate based on the oil fume concentration and the exhaust air flow rate, the method further includes:

[0149] S1203. Obtain the concentration of particulate matter in outdoor air.

[0150] S1204. When the concentration of air particulate matter reaches the third threshold, a control command is sent to the prompting component to display a prompt message.

[0151] It is understandable that a high concentration of particulate matter in the air can damage the human respiratory system. When supplying gas to the kitchen, it is necessary to ensure the quality of the supplied air to avoid the supplied air becoming a source of indoor air pollution.

[0152] In one embodiment, the concentration of particulate matter in the air is detected by an air particulate matter concentration sensor, which may be a PM2.5 sensor or other types of particulate matter concentration sensors.

[0153] An air particulate matter concentration sensor is installed outdoors or at the air intake of the air supply unit to acquire information on the concentration of particulate matter in the air and send the relevant information to the alerting unit.

[0154] In one embodiment, the prompting component may be a speaker component that conveys information about the concentration of particulate matter in the air through sound information.

[0155] In another embodiment, the notification component may also be a display screen component that conveys information about the concentration of particulate matter in the air through numbers, symbols, and warning signs.

[0156] In other embodiments, the prompt information may be a combination of sound information, image information, and indicator light information.

[0157] It should be noted that when the concentration of air particulate matter reaches the third threshold, the prompt unit will display a warning message, but the control device will not interfere with the operation of the air supply component. Whether to continue supplying air needs to be determined by the personnel in the room.

[0158] A kitchen air supply system according to a second aspect embodiment of the present invention is provided; please refer to [link / reference]. Figure 2 It includes an oil fume exhaust device 1, an air supply component 2, an oil fume detection component, and a controller 3.

[0159] The fume exhaust device 1 has an exhaust outlet connected to the outside and an exhaust inlet connected to the inside. The fume exhaust device 1 is installed on the wall of the kitchen and can exhaust the fumes and air in the kitchen to the outside.

[0160] When the kitchen doors and windows are closed, the fume exhaust device 1 will cause the indoor air pressure in the kitchen to decrease, the back pressure that the fume exhaust device 1 needs to resist when working will increase, the exhaust flow of indoor air will decrease, and when the fumes continuously generated during cooking cannot be discharged in time, they will spread in the kitchen, the working condition of the fume exhaust device 1 will deteriorate, and the fume escape phenomenon will occur.

[0161] The air supply component 2 has an air supply outlet connected to the indoor unit and an air supply inlet connected to the outdoor unit. It can draw outdoor air into the kitchen to balance the indoor air pressure, reducing the back pressure that the fume exhaust device 1 needs to withstand during operation and improving the efficiency of indoor air exhaust. The fumes in the kitchen can be exhausted in a timely manner, preventing smoke from escaping.

[0162] When the make-up air volume is large, it will create a crosswind with a high wind speed in the kitchen. When the crosswind comes into contact with the cooking fumes, it will blow the fumes away and directly enter the fume exhaust device 1. After the fumes are blown away, they spread throughout the kitchen, reducing the efficiency of fume exhaust.

[0163] Both excessively large and insufficient make-up air flow can lead to a decrease in the efficiency of fume extraction, making air management in the kitchen more difficult. Therefore, it is necessary to develop a scientific and reasonable make-up air strategy.

[0164] The kitchen air supply system provided in this embodiment of the invention includes an oil fume detection component in the kitchen, which can obtain the indoor oil fume concentration. The oil fume concentration can directly reflect the working status of the oil fume exhaust device 1, so the indoor oil fume concentration is related to the air supply requirements.

[0165] When the fume exhaust device 1 is working, there are different speeds, gears or currents, and the exhaust flow rate varies. The exhaust flow rate directly affects the indoor air pressure. Therefore, the exhaust flow rate of the fume exhaust device 1 is related to the air supply demand.

[0166] The kitchen air supply system also includes a controller 3, which is electrically connected to the fume exhaust device 1, the air supply component 2, and the fume detection component to transmit electrical signals.

[0167] In this embodiment of the invention, electrical signals can be transmitted via wired or wireless means.

[0168] The controller 3 can determine the oil fume concentration obtained by the oil fume detection component, and can also obtain the exhaust flow rate of the oil fume exhaust device 1, and determine the size of the makeup air flow rate based on the oil fume concentration and the exhaust flow rate.

[0169] After the controller 3 determines the size of the make-up air flow rate, it controls the make-up air component 2 to draw outdoor air into the room according to the make-up air flow rate.

[0170] When determining the make-up air flow rate, the controller 3 takes into account the effects of oil fume concentration and exhaust air flow rate. This avoids crosswinds caused by excessive make-up air flow rate and increases back pressure caused by insufficient make-up air flow rate. The make-up air process is scientific and reasonable, which improves the efficiency of oil fume exhaust.

[0171] In one embodiment, the fume exhaust device 1 may be a range hood.

[0172] Understandably, when the fume extraction device is working, the air pressure in the kitchen decreases, increasing the back pressure that the device needs to withstand. This reduces the efficiency of fume extraction, leading to smoke leakage. The diffused fumes increase the concentration of fumes in the indoor air, indirectly reflecting the malfunction of the fume extraction device.

[0173] The higher the concentration of cooking fumes in the indoor air, the worse the working condition of the fume exhaust device, the greater the necessity of supplemental air, and the greater the demand for supplemental air volume.

[0174] The lower the concentration of cooking fumes in the indoor air, the better the working condition of the fume exhaust device, the less necessary the replenishment air is, and the less the required replenishment air volume is.

[0175] At the same time, the supply air flow rate is positively correlated with the exhaust air flow rate. The larger the exhaust air flow rate, the more air needs to be supplied to the kitchen, and the smaller the exhaust air flow rate, the less air needs to be supplied to the kitchen.

[0176] The make-up air flow rate is positively correlated with the exhaust air flow rate and the concentration of cooking fumes. When the make-up air strategy is formulated based on the indoor air environmental factors, the efficiency of cooking fume exhaust is higher and the indoor smoke exhaust effect is better.

[0177] In the kitchen air supply system provided in this embodiment of the invention, the oil fume detection component is used to obtain the indoor oil fume concentration and can provide feedback on the working status of the oil fume exhaust device 1 or the oil fume exhaust status. To ensure the accuracy of oil fume concentration detection, it is necessary to detect characteristic gas molecules in the oil fume to make the detection results representative.

[0178] According to one embodiment of the present invention, the fume detection component includes a volatile organic compound sensor, namely a VOC (volatile organic compounds) sensor.

[0179] When the fume detection component is working, the VOC sensor can sensitively detect volatile organic compound molecules in cooking fumes. By detecting the concentration of VOC molecules, the concentration of cooking fumes can be reflected. The detection results are highly accurate and representative, and can reflect the diffusion of cooking fumes in the kitchen.

[0180] In one embodiment, the fume detection component is integrated into the controller 3 and is located in the same position as the controller 3, which helps to improve the detection effect of fume concentration.

[0181] In the kitchen air supply system provided in this embodiment of the invention, the air supply component 2 can be turned on manually or automatically by a sensor.

[0182] According to one embodiment of the present invention, the kitchen air supply system further includes a pressure sensor for acquiring indoor air pressure.

[0183] When the fume exhaust device 1 expels indoor air and fumes, the air pressure inside the kitchen decreases. When the pressure sensor detects a decrease in indoor air pressure, it indicates that the kitchen doors and windows are closed and the kitchen is in a state where air needs to be replenished.

[0184] When the indoor air pressure drops to a certain threshold, the back pressure that the fume exhaust device 1 needs to resist increases, which may cause smoke to escape. The controller 3, in conjunction with the indoor air pressure information obtained by the pressure sensor, actively activates the air supply component 2. The air supply flow rate of the air supply component 2 is determined by the fume concentration and the exhaust flow rate.

[0185] When the outdoor temperature is low, the kitchen doors and windows are closed, and the need for kitchen ventilation becomes more obvious. The ventilation component 2 draws cold outdoor air into the room, which reduces the comfort of the people in the room and may even affect their health.

[0186] According to one embodiment of the present invention, the kitchen air supply system further includes a first temperature sensor, a second temperature sensor, and a heating component.

[0187] The first temperature sensor is installed indoors to obtain the indoor air temperature. The second temperature sensor is installed outdoors to obtain the outdoor air temperature. The heating element is circuitically connected to controller 3, which controls the start-up and operation of the heating element.

[0188] The air supply component 2 has an air supply inlet and an air supply outlet, and an air supply duct is formed between the air supply inlet and the air supply outlet. The heating component is installed in the air supply duct and can heat the air supply duct under the regulation of the controller 3.

[0189] Please see Figure 2 The second temperature sensor can acquire the outdoor temperature, and the first temperature sensor can acquire the indoor temperature. When the temperature difference between indoors and outdoors is large, the heating element heats the air drawn into the room.

[0190] When the temperature difference between indoors and outdoors is small, outdoor air enters the room and the temperature difference felt by indoor occupants is not obvious, so there is no need to turn on the heating components.

[0191] When there is a large temperature difference between indoors and outdoors, such as exceeding a certain threshold, people indoors may feel uncomfortable when exposed to outdoor air. In this case, it is necessary to turn on the heating element to heat the air drawn into the room.

[0192] According to one embodiment of the present invention, multiple gradients can be set according to the size of the indoor and outdoor temperature difference. The larger the temperature difference, the higher the power of the heating component, and the smaller the temperature difference, the lower the power of the heating component.

[0193] The kitchen air supply system provided in this embodiment of the invention allows the air supply component 2 to draw outdoor air into the room to replenish the kitchen's air supply. To ensure clean indoor air, it is necessary to avoid drawing in excessive particulate matter from the outside.

[0194] According to one embodiment of the present invention, the kitchen air supply system further includes an air particulate matter concentration sensor, which is installed outdoors to obtain the air particulate matter concentration of outdoor air.

[0195] When the air supply unit is working, the air particulate matter concentration sensor detects the particulate matter concentration in the outdoor air.

[0196] When the concentration of air particulate matter is normal, remind people indoors to turn on the air supply unit 2 normally or not to interfere with its operation.

[0197] When the concentration of airborne particulate matter exceeds the standard, the system will remind indoor occupants to turn off the make-up air unit 2 or limit its operation. Of course, after receiving the reminder, indoor occupants can decide whether to turn off the make-up air unit 2 themselves.

[0198] In one embodiment, the air particulate matter concentration sensor may be a PM2.5 sensor.

[0199] According to one embodiment of the present invention, the kitchen air supply system further includes a notification component that can convey various operating parameters of the kitchen air supply system to the user.

[0200] In one embodiment, the notification component may be a speaker component that conveys information to people in the room by playing various parameter information of the kitchen air supply system during operation.

[0201] In another embodiment, the prompting component can be a display screen component, which displays various parameter information of the kitchen air supply system during operation through text and numerical information, enabling interaction with people in the room. The display screen component can also have touch functionality, allowing users to actively adjust relevant operating parameters.

[0202] In other embodiments, the prompting component may include a display screen component, a speaker component, and a signal light, etc.

[0203] The kitchen air supply system provided in this embodiment of the invention allows the controller 3 to determine the air supply flow rate of the air supply component 2 based on the concentration of cooking fumes and the exhaust flow rate.

[0204] In related technologies, the controller is mounted on the main body of the air supply unit, which is then mounted on the wall, making it difficult for users to operate. When using central air conditioning for ventilation, the wiring is complex and installation is difficult.

[0205] According to one embodiment of the present invention, the kitchen ventilation system further includes a first communication component and a second communication component.

[0206] The first communication component is electrically connected to the controller 3, and the second communication component is electrically connected to the air supply component 2. The first communication component and the second communication component are connected for communication.

[0207] The controller 3 is connected to the air supply component 2 via wireless signal communication. The controller 3 is an independent component and can be placed in a convenient location for operation, making it more convenient to use.

[0208] In one embodiment, the controller 3 further includes an adsorption component that allows the controller 3 to adhere to the surface of other objects.

[0209] The adsorption component can be any one of a magnetic adsorption structure, a vacuum adsorption structure, or a viscous adsorption structure.

[0210] When the kitchen ventilation system is working, the controller 3 can be attached to an easily accessible location for convenient access and operation.

[0211] In one embodiment, the controller 3 is attached to the fume exhaust device 1, which can detect the spread of indoor fumes in real time.

[0212] A control device according to a third aspect embodiment of the present invention, please refer to... Figure 3 The control device can implement the steps of the kitchen ventilation method provided in the first aspect embodiment of the present invention, including:

[0213] The acquisition module 310 is used to acquire the concentration of oil fumes in the indoor air and the exhaust flow rate of the oil fume exhaust device.

[0214] The determination module 320 is used to determine the makeup air flow rate based on the oil fume concentration and exhaust air flow rate.

[0215] The control module 330 is used to output control commands to the air supply component to adjust the air supply flow based on the air supply flow rate.

[0216] According to the control device provided in the embodiments of the present invention, the amount of make-up air can be determined based on the indoor oil fume concentration and the exhaust air volume of the oil fume exhaust device. By combining the make-up air volume with the indoor environment, a scientific and reasonable make-up air strategy can be formulated, which is conducive to the exhaust of indoor oil fumes and improves the quality of indoor air.

[0217] In some embodiments, the determining module 320 is further configured to determine the make-up air coefficient based on the oil fume concentration, and to determine the make-up air flow rate based on the make-up air coefficient and the exhaust flow rate.

[0218] The make-up air flow rate is positively correlated with the oil fume concentration. Different make-up air coefficients can be determined based on the oil fume concentration. The make-up air coefficients can be divided into multiple levels according to the different oil fume concentrations, and then the make-up air flow rate is determined based on the make-up air coefficients of different levels.

[0219] In some embodiments, the determining module 320 is further configured to determine a first make-up air coefficient when the oil fume concentration is greater than the target concentration threshold; and to determine a second make-up air coefficient when the oil fume concentration is not greater than the target concentration threshold; wherein the first make-up air coefficient is greater than the second make-up air coefficient, and the make-up air coefficient is positively correlated with the make-up air flow rate.

[0220] The make-up air coefficient is divided into two different levels based on the indoor oil fume concentration. The make-up air coefficients corresponding to different levels are different, which in turn affects the size of the make-up air flow.

[0221] When determining the make-up air coefficient, first determine the target concentration threshold of the oil fume, and then determine different make-up air coefficients based on the relationship between the indoor oil fume concentration and the target concentration threshold.

[0222] When the indoor oil fume concentration is greater than the target concentration threshold, the magnitude of the make-up air coefficient is determined as the first make-up air coefficient.

[0223] When the indoor oil fume concentration is not greater than the target concentration threshold, the magnitude of the make-up air coefficient is determined as the second make-up air coefficient.

[0224] When the concentration of cooking fumes is high, the demand for make-up air is greater. Therefore, the first make-up air coefficient is greater than the second make-up air coefficient, and the make-up air coefficient is positively correlated with the make-up air flow rate.

[0225] In some embodiments, the determining module 320 is further configured to determine the make-up air flow rate based on the product of the make-up air coefficient and the exhaust air flow rate.

[0226] The make-up air flow rate is equal to the product of the make-up air coefficient and the exhaust air flow rate. It takes into account both the influence of indoor oil fume concentration on the make-up air flow rate and the influence of exhaust air flow rate on the make-up air flow rate.

[0227] In some embodiments, the acquisition module 310 is further configured to acquire indoor air pressure, and the control module 330 is further configured to output a control command for starting the air supply component when the indoor air pressure reaches a first threshold.

[0228] When the difference between indoor air pressure and atmospheric pressure is small, the back pressure resisted by the fume exhaust device is small, the efficiency of fume exhaust is high, and there is no fume escape. At this time, it is not necessary to start the exhaust component.

[0229] When the difference between indoor air pressure and atmospheric pressure is large, the back pressure resisted by the fume extraction device is greater, resulting in lower fume extraction efficiency and fume leakage. By using the air pressure at which smoke leakage occurs as the first threshold, the control device actively activates the air supply component when the indoor air pressure reaches this threshold, making kitchen air supply more intelligent and flexible.

[0230] In some embodiments, the acquisition module 310 is further configured to acquire indoor temperature and outdoor temperature, and the control module 330 is further configured to output a control command for heating to the heating component when the difference between indoor temperature and outdoor temperature reaches a second threshold.

[0231] When the temperature difference between indoors and outdoors is small, outdoor air entering the room will not lower the indoor temperature or the temperature drop will be minimal, so there is no need to turn on the heating components.

[0232] When there is a large temperature difference between indoors and outdoors, the entry of cold outdoor air into the room can cause a sharp drop in indoor temperature, affecting the comfort of people indoors. In this case, it is necessary to turn on the heating components.

[0233] In some embodiments, the acquisition module 310 is further configured to acquire the concentration of air particulate matter in outdoor air, and the control module 330 is further configured to issue a control command to the prompting component to display prompt information when the concentration of air particulate matter reaches a third threshold.

[0234] An air particulate matter concentration sensor is installed outdoors or at the air intake of the air supply unit to acquire information on the concentration of particulate matter in the air and send the relevant information to the alerting unit.
