Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and more specifically, to a kitchen appliance, its control method, and related devices. Background Technology

[0002] The kitchen is the primary place for cooking, and the quality of its air quality directly impacts the cooking experience. Cooking consumes a large amount of oxygen and generates significant oil fume pollution. While range hoods are typically used to vent these fumes outdoors, in well-sealed kitchens without sufficient fresh air supply, the limited oxygen available is simultaneously expelled outdoors by the range hood, potentially leading to oxygen deficiency. Furthermore, the area around the stove is a high-temperature environment, where cooks are subjected to both oil fume exposure and intense heat during cooking.

[0067] The kitchen appliance, its control method, and related devices provided by this invention integrate a range hood module, a refrigeration module, and a fresh air module. During cooking, these modules control smoke, provide cooling, and introduce fresh air, effectively enhancing the cooking experience. Specifically, the evaporator of the refrigeration module is located in the first cavity of the unit, while the condenser and compressor are located in the second cavity. This means the refrigeration module is integrated within the unit, eliminating the need for separate indoor and outdoor units, resulting in a compact structure and convenient installation. A circulating fan is installed in the first cavity, and the outlet of the fresh air module is connected to the inlet of the circulating fan. The circulating fan is configured to allow fluid in the first cavity to flow out through a mixing air outlet. The activation of the refrigeration module and the mixing of cold and fresh air can be determined based on indoor and outdoor temperatures. For example, when the cooling module is turned on in summer, cold air mixes with fresh air and is output from the mixing air outlet. The unit has a guide structure pivotally connected at the mixing air outlet, and when the guide structure rotates, it can guide the fluid to flow upward and / or downward. When the guide structure rotates, the mixing air outlet forms a first air outlet that outputs air upward and a second air outlet that outputs air downward. The airflow output from the second air outlet can form an air curtain. The mixed gas is delivered to the kitchen through the first air outlet to reduce the air temperature in the kitchen to a certain extent and increase the oxygen content in the kitchen. The mixed gas air curtain output through the second air outlet can assist the range hood module in controlling smoke, effectively reduce the escape of oil fumes, and also effectively increase the oxygen content in the stove area.

[0090] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0091] To address the issues of ventilation, high temperature, and cooking fumes in the kitchen during cooking, this embodiment provides a kitchen appliance, its control method, and related devices. This kitchen appliance integrates a range hood module, a cooling module, and a fresh air module, enabling smoke control, cooling, and fresh air introduction during cooking, effectively improving the cooking experience. This kitchen appliance can be, for example, a range hood or a similar appliance, such as an ultra-thin range hood.

[0092] See Figures 1-8 As shown, the kitchen appliance provided in this embodiment includes a range hood module, a refrigeration module, a fresh air module, a control module, and a body 400. The body 400 includes a first cavity 410, a second cavity 420, and a third cavity 430 that are isolated from each other, wherein the first cavity 410 and the second cavity 420 are isolated from each other. Optionally, the first cavity 410, the second cavity 420, and the third cavity 430 are isolated from each other, that is, the first cavity 410, the second cavity 420, and the third cavity 430 are not connected to each other. The specific arrangement of the first cavity 410, the second cavity 420, and the third cavity 430 within the body 400 can be determined according to the actual situation. For example, the first cavity 410 and the second cavity 420 are located at the front of the body 400, part of the third cavity 430 is located below the first cavity 410 and / or the second cavity 420, and part of the third cavity 430 is located behind the first cavity 410 and / or the second cavity 420. Where A1 and / or A2 means: only A1, or only A2, or A1 and A2.

[0093] The refrigeration module includes an evaporator 210, a condenser 220, and a compressor 230 for forming a cooling circulation loop. The evaporator 210 is disposed in the first cavity 410 and configured to reduce the temperature within the first cavity 410. The condenser 220 and the compressor 230 are both disposed in the second cavity 420. Optionally, the evaporation air inlet 211 of the evaporator 210 is disposed on the body 400, and the evaporation air outlet of the evaporator 210 communicates with the first cavity 410. Optionally, the condensation air inlet 221 of the condenser 220 is disposed on the body 400, and the air outlet of the condenser 220 communicates with the second cavity 420. The body 400 is provided with a heat exhaust port 241 communicating with the second cavity 420. Gas in the kitchen flows into the condenser 220 from the condensation air inlet 221, exchanges heat with the condenser 220 in operation, is heated, flows to the second cavity 420, and is then discharged outdoors through the heat exhaust port 241.

[0094] The first cavity 410 is equipped with a circulating fan 250; the fresh air module includes a fresh air inlet 311 installed on the body 400 and connected to the outside. The air outlet of the fresh air module is connected to the inlet of the circulating fan 250, which allows the fresh air from the fresh air module to mix with the indoor circulating air from the circulating fan 250 to form a mixed air.

[0095] The body 400 is provided with a mixing air outlet 260, and a guide structure 440 is pivotally connected to the body 400 at the mixing air outlet 260. When the guide structure 440 rotates, it can guide the fluid to flow upward and / or downward. The circulating fan 250 is configured to allow the fluid in the first cavity 410 to flow out from the mixing air outlet 260. Optionally, the mixing air outlet 260 is configured as a first air outlet that can guide the fluid to flow upward and / or a second air outlet that can guide the fluid to flow downward when the guide structure 440 rotates. The airflow output from the second air outlet can form an air curtain. The circulating fan 250 helps to output the air in the first cavity 410 from the mixing air outlet 260, that is, from the first air outlet and / or the second air outlet. For example, the mixed air after the cold air cooled by the evaporator 210 in the first cavity 410 is mixed with fresh air and delivered to the kitchen room from the first air outlet, which can reduce the temperature in the kitchen room and increase the oxygen content in the kitchen room. The mixed gas air curtain is output from the second air outlet to the vicinity of the stove, which can assist the range hood module in controlling smoke, effectively reduce the escape of oil fumes, and effectively increase the oxygen content in the stove area.

[0096] The range hood module is disposed within the third cavity 430; optionally, the range hood module includes a range hood fan 130 disposed within the third cavity 430; the range hood fan 130 is electrically connected to the control module to facilitate automatic control of the range hood fan 130. In this embodiment, the third cavity 430 serves as an independent channel, allowing the range hood module to exhaust fumes into the kitchen's common exhaust duct.

[0097] The range hood module, cooling module, fresh air module, circulating fan 250, and air guide structure 440 are electrically connected to the control module. The control module is configured to control the opening and closing of the cooling module based on the outdoor and indoor temperatures of the kitchen area where the kitchen appliances are located. The control module is also configured to control the operating mode of the range hood module based on the cooking status of the corresponding stove, and to control the operating modes of the fresh air module, air guide structure 440, and the cooling module (when it is on) based on the temperature difference between the outdoor and indoor temperatures and the operating mode of the range hood module. For details on the specific working principle and control method of the control module, please refer to the description of kitchen appliance control methods and devices below; further details will not be elaborated here.

[0098] The control module of this embodiment can also adopt the following structure: the control module includes a memory, a processor, and a communication module; the memory, processor, and communication module are electrically connected directly or indirectly to realize data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines. The memory is used to store programs or data; the memory can be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable read-only memory (EPROM), electrically erasable read-only memory (EEPROM), etc. The processor is used to read / write the data or programs stored in the memory and execute corresponding functions. The communication module is used to establish a communication connection between the control module and other communication terminals through a network, and to send and receive data through the network.

[0099] In this embodiment, the kitchen appliances are installed in the kitchen. Gas in the kitchen, for example, flows into the evaporator 210 from the evaporator inlet 211, is cooled by the operating evaporator 210, and then flows into the first cavity 410, where it mixes with the fresh air from the fresh air module. For example, driven by the fresh air fan 310, outdoor fresh air flows into the first cavity 410 from the fresh air inlet 311, mixes in the first cavity 410, and then flows into the mixing air outlet 260. The mixing air outlet 260 can supply a mixture of fresh and cool air to the kitchen, effectively increasing the oxygen content in the enclosed space and reducing the indoor temperature to some extent. The second air outlet of the mixing air outlet 260 can form an air curtain during cooking, effectively increasing the oxygen content in the stove area and assisting the range hood module in controlling smoke, effectively reducing the chance of oil fumes escaping. In existing technologies, air curtain range hoods draw air from the kitchen interior space to create an air curtain, which can easily lead to the diffused airflow containing oil fumes being reintroduced into the air curtain structure and blown out again, thus causing secondary oil fume diffusion. The kitchen appliance described in this embodiment effectively improves the problem of secondary oil fume diffusion.

[0100] The kitchen appliance described in this embodiment is connected to the first cavity 410 through the air outlet duct of the fresh air module. The evaporator 210 is configured to lower the temperature inside the first cavity 410, allowing the first and second air outlets connected to the first cavity 410 to output a mixed air at a lower temperature. For example, when the evaporator 210 is in operation, such as in summer, the cold air and fresh air inside the first cavity 410 mix to form a mixed air. The relatively lower temperature mixed air can be output from above (e.g., the first air outlet) and / or below (e.g., the second air outlet) according to the swivel angle of the air guide structure 440. The first air outlet, while increasing the oxygen content in the kitchen by introducing fresh air, can also lower the temperature in the kitchen to a certain extent. The second air outlet outputs a relatively lower temperature mixed air curtain during cooking, which not only effectively increases the oxygen content in the stove area but also cools the stove area, providing a cooler feeling for the user. It also reduces the flow speed of cooking fumes due to the cold air, thereby effectively reducing the chance of cooking fumes escaping. For example, when the evaporator 210 is not in operation, such as in winter, the fresh air provided by the fresh air module can be mixed with the indoor circulating air of the circulating fan 250 to form a mixed air. The mixed air can be output from the first air outlet and / or the second air outlet, so that the first air outlet and / or the second air outlet can be used to input the mixed air at a relatively mild temperature into the kitchen room, effectively avoiding the direct input of cold outdoor air into the kitchen room and causing discomfort to the user.

[0101] The kitchen appliance described in this embodiment integrates a range hood module, a cooling module, and a fresh air module. It can control smoke, cool the kitchen, and introduce fresh air during cooking, effectively improving the cooking experience. Specifically, the evaporator 210 of the cooling module is located in the first cavity 410 of the unit 400, while the condenser 220 and compressor 230 are both located in the second cavity 420 of the unit 400. That is, the cooling module is integrated within the unit 400, eliminating the need for separate indoor and outdoor units, resulting in a compact structure and convenient installation. A circulating fan 250 is installed in the first cavity 410, and the air outlet of the fresh air module is connected to the inlet of the circulating fan 250. The circulating fan 250 is configured to allow the fluid in the first cavity 410 to flow out through the mixing air outlet 260. This allows the system to determine whether the cooling module is activated and whether the cold air is mixed with the fresh air to create a mixed airflow, based on the indoor and outdoor temperatures. For example, when the cooling module is turned on in summer, cold air and fresh air are mixed and output from the mixing air outlet 260. A guide structure 440 is pivotally connected to the mixing air outlet 260 via the body 400. When the guide structure 440 rotates, it can guide the fluid to flow upward and / or downward. When the guide structure 440 rotates, the mixing air outlet 260 forms a first air outlet that outputs air upward and a second air outlet that outputs air downward. The airflow output from the second air outlet can form an air curtain. The mixed gas is delivered to the kitchen through the first air outlet to reduce the air temperature in the kitchen to a certain extent and increase the oxygen content in the kitchen. The mixed gas air curtain output through the second air outlet can assist the range hood module in controlling smoke, effectively reduce the escape of oil fumes, and effectively increase the oxygen content in the stove area.

[0102] The kitchen appliance in this embodiment uses a condenser 220 for cooling, which has higher cooling efficiency and better cooling effect compared to using semiconductor cooling technology.

[0105] Optionally, when the air guide structure 440 is in operation, the control module controls the circulating fan 250 to operate accordingly.

[0109] Optionally, the air outlet duct of part of the range hood fan 130 passes through the first cavity 410; when the evaporator 210 in the first cavity 410 is in working condition, the oil fumes in the air outlet duct of the range hood fan 130 passing through the first cavity 410 are very likely to be cooled down, which helps the oil fumes condense.

[0110] Optionally, the exhaust duct of part of the range hood fan 130 passes through the second cavity 420; when the condenser 220 in the second cavity 420 is in operation, the oil fumes in the exhaust duct of the range hood fan 130 passing through the second cavity 420 are very likely to be heated, which helps to exhaust the oil fumes.

[0125] This embodiment also provides a kitchen appliance control method, which can be applied to the kitchen appliances described in any of the above embodiments; the technical features of the kitchen appliances disclosed above are also applicable to this kitchen appliance control method, and the disclosed technical features of the kitchen appliances will not be described again. Furthermore, the above-mentioned kitchen appliances can employ the following kitchen appliance control method, and the technical features of the following kitchen appliance control method are also applicable to the above-mentioned kitchen appliances.

[0126] The following combination Figure 9 and Figure 10 The kitchen appliance control method provided in this embodiment is described below. The kitchen appliance control method includes:

[0127] Step S100: Turn on the power to the kitchen appliances.

[0128] Step S200: Obtain the outdoor temperature of the kitchen appliance location and the indoor temperature of the kitchen area; when the indoor temperature is within a first temperature range, the cooling module remains off; when both the indoor and outdoor temperatures are within a second temperature range, the cooling module is turned on; for example, the first temperature range is greater than 10℃ and less than 26℃, and the second temperature range is greater than or equal to 26℃; another example, the first temperature range is greater than 10℃ and less than 28℃, and the second temperature range is greater than or equal to 28℃; yet another example, the first temperature range is greater than -1℃ and less than 26℃, and the second temperature range is greater than or equal to 26℃. In this embodiment, the first and second temperature ranges can be determined based on factors such as the ambient temperature where the kitchen appliance is used.

[0129] Step S300: Obtain the cooking status of the corresponding stove of the kitchen appliance, and control the working mode of the range hood module according to the cooking status of the stove; according to the difference between the outdoor temperature and the indoor temperature and the working mode of the range hood module, control the operating mode of the fresh air module, the operating mode of the air guide structure 440 and the operating mode of the cooling module that is in the open state.

[0130] The kitchen appliance control method described in this embodiment can determine whether to turn on the cooling module based on the indoor and outdoor temperatures. When both the indoor and outdoor temperatures are within the second temperature range, the cooling module is turned on to lower the indoor temperature. The operating mode of the range hood module is controlled according to the cooking status of the stove. Based on the difference between the outdoor and indoor temperatures and the operating mode of the range hood module, the operating mode of the fresh air module, the operating mode of the air guide structure 440, and the operating mode of the cooling module that is in the on state are controlled accordingly.

[0131] In some embodiments, the specific operating modes of the range hood module may include standby mode, low range hood speed, medium range hood speed, and high range hood speed. The low range hood speed is, for example, the speed at which the range hood is delayed and shuts off after cooking; the medium range hood speed is, for example, the speed at which less smoke and heat are generated, such as the speed at which the range hood is used during steaming or boiling; and the high range hood speed is, for example, the speed at which more smoke and heat are generated, such as the speed at which the range hood is used during frying or stir-frying.

[0132] Optionally, when the air guide structure 440 swings to the first angle, the first air outlet is closed, and the second air outlet is fully opened and outputs airflow downwards; when the air guide structure 440 swings to the second angle, both the first and second air outlets are partially covered, and the area covered by the first air outlet is smaller than the area covered by the second air outlet; when the air guide structure 440 swings to the third angle, the second air outlet is closed, and the first air outlet is fully opened and outputs airflow upwards. Optionally, when the air guide structure 440 swings to the second angle, 20% of the area of ​​the first air outlet is covered so that 80% of the area of ​​the first air outlet is open, and 80% of the area of ​​the second air outlet is covered so that 20% of the area of ​​the second air outlet is open; for example, the total airflow output from the mixing air outlet 260, wherein 80% of the total airflow is delivered from the first air outlet and 20% of the total airflow is delivered from the second air outlet. In some embodiments, when the air guide structure 440 is rotated to the second angle, the area covered by the first air outlet and the area covered by the second air outlet can be other values; for example, 30% of the area of ​​the first air outlet is covered so that 70% of the area of ​​the first air outlet is open, and 70% of the area of ​​the second air outlet is covered so that 30% of the area of ​​the second air outlet is open; or, 25% of the area of ​​the first air outlet is covered so that 75% of the area of ​​the first air outlet is open, and 75% of the area of ​​the second air outlet is covered so that 25% of the area of ​​the second air outlet is open, etc.

[0133] Optionally, when the range hood module is in standby mode, the fresh air module remains closed, with no air supply from the first and second air outlets; for example, the mixing air outlet 260 is closed. Optionally, when the range hood module is in standby mode, if the indoor temperature falls within a first temperature range, such as 10℃ < indoor temperature < 26℃, the range hood module, cooling module, and fresh air module are all closed. Figure 5 As shown; when the range hood module is in standby mode, and both the indoor and outdoor temperatures are within the second temperature range (e.g., indoor temperature ≥ 26℃, outdoor temperature ≥ 26℃), both the range hood module and the fresh air module are off, while the cooling module is on. Figure 6 As shown, optionally, when the range hood module is in standby mode, the fresh air module is in the off state, the cooling module is in the low-power state, and the air guide structure 440 is directed upward (at this time, the first air outlet is 100% open, the second air outlet is closed, and the air guide structure 440 is rotated to the third angle). The cold air blows upward, cooling the kitchen room. Since hot air rises and cold air falls, the upward air guide helps the cold air cover the entire space, effectively preventing the stratification of hot and cold air in the kitchen room.

[0134] Optionally, when the range hood module is in the medium-speed range hood mode, the fresh air module is controlled to operate in the low-speed fresh air mode. When the indoor temperature is within a first temperature range, for example, 10℃ < indoor temperature < 26℃, the cooling module is in the off state, and the air guide structure 440 swings to a first angle, for example, swinging the air guide structure 440 downwards to close the first air outlet and fully open the second air outlet (i.e., the second air outlet is 100% open). The opened second air outlet can form a downward air curtain. If the indoor temperature is within the first temperature range, and 26℃ > outdoor temperature ≥ indoor temperature, the air guide structure 440 swings to a first angle, for example, swinging the air guide structure 440 downwards to close the first air outlet and open the second air outlet 100%, which can introduce outdoor air that is higher than the room temperature and improve indoor comfort. When both indoor and outdoor temperatures fall within the second temperature range (e.g., indoor temperature ≥ 26℃, outdoor temperature ≥ 26℃), the cooling module is activated. The air guide structure 440 rotates to a second angle, for example, so that 20% of the first air outlet is covered, resulting in 80% of the first air outlet being open, and 80% of the second air outlet is covered, resulting in 20% of the second air outlet being open. The mixing air outlet 260 forms an upward-facing first air outlet and a downward-facing second air outlet when the air guide structure 440 rotates; the airflow from the second air outlet forms an air curtain. If both indoor and outdoor temperatures fall within the second temperature range, and 26℃ ≤ outdoor < indoor temperature, the air guide structure 440 simultaneously guides airflow both vertically and vertically, opening 80% of the first air outlet and 20% of the second air outlet. This allows for the introduction of relatively cooler outdoor airflow to assist in indoor cooling. The 20% opening of the second air outlet forms an air curtain. Figure 7 As shown. When the range hood is in medium mode, the fresh air module operates in low mode to prevent excessive airflow from the air curtain from dispersing the fumes. Air is directed upwards through 80% opening of the first air outlet to assist in indoor cooling.

[0135] Optionally, when the range hood module is in high-speed operation, it controls the fresh air module to operate in medium-speed fresh air mode. When the indoor temperature is within a first temperature range, such as 10℃ < indoor temperature < 26℃, the cooling module is in a closed state, and the air guide structure 440 swings to a first angle, such as swinging downwards to close the first air outlet and fully open the second air outlet (i.e., the second air outlet is 100% open). The opened second air outlet can form a downward air curtain. If the indoor temperature is within the first temperature range, and 26℃ > outdoor temperature ≥ indoor temperature, the air guide structure 440 swings to a first angle, such as swinging downwards to close the first air outlet and fully open the second air outlet. The airflow output from the second air outlet can form an air curtain, which can introduce outdoor air that is higher than the room temperature, improving indoor comfort. When both indoor and outdoor temperatures fall within the second temperature range (e.g., indoor temperature ≥ 26℃, outdoor temperature ≥ 26℃), the cooling module is activated. The air guide structure 440 rotates to a second angle, for example, so that 20% of the first air outlet is covered, resulting in 80% of the first air outlet being open, and 80% of the second air outlet is covered, resulting in 20% of the second air outlet being open. The mixing air outlet 260 forms an upward-facing first air outlet and a downward-facing second air outlet when the air guide structure 440 rotates; the airflow from the second air outlet forms an air curtain. If both indoor and outdoor temperatures fall within the second temperature range, and 26℃ ≤ outdoor < indoor temperature, the air guide structure 440 simultaneously guides airflow both vertically and vertically, opening 80% of the first air outlet and 20% of the second air outlet. This allows for the introduction of relatively cooler outdoor airflow to assist in indoor cooling. The 20% opening of the second air outlet forms an air curtain. Figure 7 As shown. When the range hood is in medium mode, the fresh air module operates in medium fresh air mode to prevent the air curtain from blowing away the cooking fumes due to excessive airflow. Air is directed upwards through the first air outlet, which is opened to 80% to assist in indoor cooling.

[0136] Optionally, when the range hood module is in the low-speed mode, the fresh air module is controlled to operate in the high-speed fresh air mode; at the same time, the air guide structure 440 is rotated to a third angle, for example, the air guide structure 440 is rotated upwards to make the first air outlet fully open and the second air outlet closed; by rotating the air guide structure 440 upwards to make the first air outlet fully open and the second air outlet closed, the airflow can be directed upwards to prevent the introduced fresh air from being immediately sucked away by the range hood, and the residual oil fume airflow can be absorbed and discharged first, thereby improving indoor comfort.

[0137] In an optional embodiment, the cooling module further includes a heat exhaust fan 240; the heat exhaust fan 240 is disposed in the second cavity 420 and is configured to cause the fluid in the second cavity 420 to flow out toward the heat exhaust port 241. By using the heat exhaust fan 240 to increase the airflow velocity in the second cavity 420, heat dissipation is facilitated.

[0138] Optionally, when the cooling module is in the off state, both the exhaust fan 240 and the circulating fan 250 are in the off state; when the cooling module is in any of the following modes: low cooling mode, medium cooling mode, and high cooling mode, both the exhaust fan 240 and the circulating fan 250 are in the on state; the fan speed of the exhaust fan 240 in the low cooling mode is lower than the fan speed of the exhaust fan 240 in the medium cooling mode; the fan speed of the exhaust fan 240 in the medium cooling mode is lower than the fan speed of the exhaust fan 240 in the high cooling mode; the fan speed of the circulating fan 250 in the low cooling mode is lower than the fan speed of the circulating fan 250 in the medium cooling mode; the fan speed of the circulating fan 250 in the medium cooling mode is lower than the fan speed of the circulating fan 250 in the high cooling mode.

[0139] In an optional embodiment, when the range hood module is in standby mode, the range hood fan 130 located in the third cavity 430 is in a closed state; when the range hood module is in any of the following working modes: low, medium, or high, the range hood fan 130 is in an open state; the wind speed of the range hood fan 130 in the low mode is lower than the wind speed of the range hood fan 130 in the medium mode; the wind speed of the range hood fan 130 in the medium mode is lower than the wind speed of the range hood fan 130 in the high mode.

[0140] In an optional embodiment, when the fresh air module is in the off state, the fresh air fan 310 disposed in the first cavity 410 is in the off state; when the fresh air module is in any of the fresh air low-speed mode, fresh air medium-speed mode, and fresh air high-speed mode, the fresh air fan 310 is in the on state; the air speed of the fresh air fan 310 in the fresh air low-speed mode is less than the air speed of the fresh air fan 310 in the fresh air medium-speed mode; the air speed of the fresh air fan 310 in the fresh air medium-speed mode is less than the air speed of the fresh air fan 310 in the fresh air high-speed mode.

[0141] See Figure 9 and Figure 10 As shown, in the optional scheme of this embodiment, step S300, "obtaining the cooking status of the stove corresponding to the kitchen appliance, and controlling the working mode of the range hood module according to the cooking status of the stove," specifically includes:

[0142] If the oxygen concentration in the stove area is the same as the indoor oxygen concentration, and the trend of oxygen concentration change in the stove area remains unchanged, it is determined that the stove is not turned on, and the corresponding control range hood module is in standby mode; where the indoor oxygen concentration is the oxygen concentration in the non-stove area of ​​the kitchen.

[0143] If the indoor oxygen concentration is greater than the oxygen concentration in the stove area and the minimum oxygen concentration threshold, and the oxygen concentration in the stove area gradually decreases, then it is determined that the stove is on medium heat, and the corresponding control of the range hood module is set to medium mode. The minimum oxygen concentration threshold is the preset oxygen concentration in the stove area when the stove is on high heat. The medium mode of the range hood is, for example, the setting where less oil smoke and heat are generated, such as the setting of the range hood when steaming or cooking.

[0144] If the oxygen concentration in the stove area is less than or equal to the minimum oxygen concentration threshold, and the oxygen concentration trend in the stove area remains unchanged, then it is determined that the stove is turned on high, and the corresponding control of the range hood module is set to the high-level range hood mode. The high-level range hood mode is, for example, the setting that produces more oil fumes and heat, such as the setting that the range hood is in when frying, stir-frying, or deep-frying.

[0145] If the indoor oxygen concentration is greater than the oxygen concentration in the stove area and the oxygen concentration in the stove area is greater than the minimum oxygen concentration threshold, and the oxygen concentration in the stove area gradually increases, then it is determined that the stove is turned off, and the corresponding control of the range hood module is set to the low-speed mode; the low-speed mode is, for example, the setting when the range hood is turned off after cooking with a delay.

[0146] In this embodiment, the oxygen concentration in the stove area and the indoor oxygen concentration can be collected using existing oxygen concentration sensors.

[0147] Optionally, in this embodiment, "obtaining the cooking status of the corresponding stove of the kitchen appliance and controlling the working mode of the range hood module according to the cooking status of the stove" can also be done in other ways, specifically including:

[0148] If the stove is not lit, it is determined to be in standby mode, and the corresponding control for the range hood module is also set to standby mode. When the range hood module is in standby mode, there is no smoke or heat generated.

[0149] If the stove is switched from off or high power to medium or low power, it is determined that the stove is on medium heat, and the corresponding control module of the range hood is in medium mode. In medium mode, such as when steaming or cooking, there is relatively less oil smoke.

[0150] If the stove is turned off or switched from low to high heat, it is determined that the stove is on high heat, and the corresponding control module of the range hood is in high-level mode. High-level mode of the range hood is such as when frying, stir-frying or deep-frying, at which time there is relatively more oil smoke and relatively more heat.

[0151] If the stove is turned off after it has been running, the corresponding control module for the range hood will be set to low-speed mode. The low-speed mode can be used to delay the shutdown after cooking in order to absorb a small amount of residual oil fumes.

[0152] Optionally, the kitchen appliance obtains the cooking status information of the stove through wireless transmission, which may include one or more of Bluetooth, infrared, WiFi and radio, or other wireless transmission methods.
