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.

[0094] 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.

[0095] See Figures 1-8As 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, 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.

[0096] 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 unit body 400 is provided with a cold air outlet 260 communicating with the first cavity 410; the cold air outlet 260 is configured to supply air to the indoor environment. 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 unit 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 unit body 400, the air outlet of the condenser 220 communicates with the second cavity 420, and the unit body 400 is provided with a heat exhaust port 241 communicating with the second cavity 420.

[0097] The fresh air module includes a fresh air inlet 311 disposed on the body 400 and connected to the outside, a second air inlet 314 connected to the first cavity 410, and a first fresh air outlet 312 and a second air curtain outlet 313 disposed on the body 400 and connected to the fresh air module's air outlet channel. The first fresh air outlet 312 is configured to supply air to the indoor environment, and the second air curtain outlet 313 is configured to form an air curtain in the stove area. Optionally, the fresh air module includes a fresh air fan 310 disposed on the first cavity 410; the fresh air inlet 311 and the second air inlet 314 are respectively connected to the air inlet channel of the fresh air fan 310; the fresh air fan 310 is electrically connected to a control module to facilitate automatic control of the fresh air fan 310.

[0098] 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.

[0099] The range hood module, cooling module, and fresh air module 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. Based on the operating mode of the range hood module and the temperature difference between the outdoor and indoor temperatures, the control module controls the opening and closing of the second air inlet 314 to control whether the gas in the first cavity 410 mixes with the fresh air from the fresh air module. Based on the operating mode of the range hood module, the control module controls the operating mode of the fresh air module and the operating mode of the cooling module when it is in the on state. For the specific working principle and control method of the control module, please refer to the kitchen appliance control methods and kitchen appliance control devices described below, which will not be repeated here.

[0100] 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.

[0101] In this embodiment, after the kitchen appliances are installed in the kitchen, the gas in the kitchen flows into the evaporator 210 from the evaporator inlet 211, is cooled by the evaporator 210 in operation, and then flows into the first cavity 410, and then outputs cold air from the first cavity 410 through the cold air outlet 260. For example, the gas in the kitchen flows into the condenser 220 from the condenser inlet 221, is heated after heat exchange with the condenser 220 in operation, and then flows into the second cavity 420, and then is discharged to the outside through the heat exhaust outlet 241. As another example, driven by the fresh air fan 310, outdoor fresh air flows into the fresh air inlet 311 and flows to the first fresh air outlet 312 and / or the second air curtain outlet 313. The first fresh air inlet 312 introduces fresh air into the kitchen, effectively increasing the oxygen content in the enclosed space. The second air curtain inlet 313 forms an air curtain during cooking, effectively increasing the oxygen content in the stove area and assisting the range hood module in controlling smoke, thus effectively reducing the chance of oil fumes escaping. In existing technologies, air curtain range hoods draw air from the kitchen space for air curtain distribution, which may lead to the diffused airflow carrying oil fumes being reintroduced into the air curtain structure and blown out, easily causing secondary oil fume diffusion. The kitchen appliance described in this embodiment effectively improves the problem of secondary oil fume diffusion.

[0102] The kitchen appliance described in this embodiment is connected to the first cavity 410 via the second air inlet 314, allowing fluid in the first cavity 410 to be injected into the fresh air duct to mix with the fresh air and form a mixed airflow. For example, when the evaporator 210 is in operation, such as in summer, cold air from the first cavity 410 is injected into the fresh air duct to cool the fresh air and form a mixed airflow. The relatively low-temperature mixed airflow can be output from the first fresh air outlet 312 and / or the second air curtain outlet 313. The first fresh air outlet 312, while increasing the oxygen content in the kitchen by introducing fresh air, can also reduce the temperature in the kitchen to a certain extent. The second air curtain outlet 313 outputs a relatively low-temperature mixed airflow curtain during cooking, which not only effectively increases the oxygen content in the stove area but also cools the stove area, providing a cooling effect 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 first chamber 410 circulates indoor air in the kitchen. The indoor air in the kitchen is injected into the fresh air duct to heat the fresh air and form a mixed air. The mixed air can be output from the first fresh air supply port 312 and / or the second air curtain supply port 313, so that the first fresh air supply port 312 and / or the second air curtain supply port 313 can input the mixed air at a relatively mild temperature into the kitchen, effectively avoiding the direct input of cold outdoor air into the kitchen and causing discomfort to the user.

[0103] The kitchen appliance described in this embodiment integrates a range hood module, a cooling module, and a fresh air module.

[0132] 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.

[0133] 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:

[0134] Step S100: Turn on the power to the kitchen appliances.

[0135] Step S200: Obtain the outdoor and indoor temperatures of the kitchen area where the kitchen appliance is located; 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 is that 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 is that 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.

[0136] 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; control the opening and closing of the second air inlet 314 according to the working mode of the range hood module and the difference between the outdoor temperature and the indoor temperature; control the operating mode of the fresh air module and the operating mode of the cooling module that is in the open state according to the working mode of the range hood module.

[0137] The kitchen appliance control method described in this embodiment can determine whether to activate the cooling module based on indoor and outdoor temperatures. When both indoor and outdoor temperatures fall within a second temperature range, the cooling module is activated 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 operating mode of the range hood module and the temperature difference between the outdoor and indoor temperatures, the second air inlet is controlled to open accordingly, thereby controlling whether the gas in the first cavity 410 mixes with the fresh air from the fresh air module. The operating mode of the fresh air module and the operating mode of the cooling module (which is currently activated) are also controlled according to the operating mode of the range hood module.

[0138] 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.

[0139] Optionally, when the range hood module is in standby mode, the fresh air module remains off. Optionally, when the range hood module is in standby mode, if the indoor temperature is within a first temperature range (e.g., 10℃ < indoor temperature < 26℃), the range hood module, cooling module, and fresh air module are all off. If the range hood module is in standby mode and both the indoor and outdoor temperatures are within a second temperature range (e.g., indoor temperature ≥ 26℃ and outdoor temperature ≥ 26℃), the range hood module and fresh air module are both off, while the cooling module is on. Further optionally, when the range hood module is in standby mode and both the indoor and outdoor temperatures are within the second temperature range, if the outdoor temperature is < indoor temperature, the cooling module operates at a low setting; if the outdoor temperature is ≥ indoor temperature, the cooling module operates at a medium setting.

[0140] Optionally, when the range hood module is in either the medium or high operating mode, the fresh air module is controlled to operate in the low fresh air mode; simultaneously, the first fresh air outlet 312 and the second air curtain outlet 313 are opened, or the second air curtain outlet 313 is opened; by operating the fresh air module in the low fresh air mode when the range hood is in the medium or high operating mode, the excessive airflow output by the second air curtain outlet 313 may blow away the fumes.

[0141] Optionally, when the range hood module is in the low-speed mode, the fresh air module is controlled to operate and is in the high-speed fresh air mode; at the same time, the first fresh air outlet 312 and / or the second air curtain outlet 313 are opened.

[0142] SeeFigure 9 and Figure 10 As shown, in the optional scheme of this embodiment, when the indoor temperature is within the first temperature range, for example, 10℃ < indoor temperature < 26℃, the cooling module is in the off state and the range hood module is in the non-standby state. If the outdoor temperature is lower than the indoor temperature, the second air inlet 314 is opened so that the fluid in the first cavity 410 flows into the air intake channel of the fresh air fan 310 and mixes with the fluid in the air intake channel of the fresh air fan 310 to assist in the heating of fresh air and improve user comfort. If the outdoor temperature is greater than or equal to the indoor temperature, the second air inlet 314 is kept closed to introduce outdoor air with a higher temperature than the ambient temperature and improve indoor comfort.

[0143] See Figure 9 and Figure 10 As shown, in the optional scheme of this embodiment, when both the indoor and outdoor temperatures are within the second temperature range and the range hood module is in non-standby mode, the second air inlet 314 is opened to allow the fluid in the first cavity 410 to flow into the air intake channel of the fresh air fan 310 and mix with the fluid in the air intake channel of the fresh air fan 310. Where both the indoor and outdoor temperatures are within the second temperature range, for example, when the indoor temperature is ≥26℃ and the outdoor temperature is ≥26℃, the cooling module is in the on state. If the outdoor temperature is lower than the indoor temperature, opening the second air inlet 314 allows the outdoor fresh air to help lower the indoor temperature, improving user comfort; if the outdoor temperature is greater than or equal to the indoor temperature, opening the second air inlet 314 lowers the temperature of the high-temperature outdoor fresh air, improving user comfort.

[0144] See Figure 9 and Figure 10 As shown, in some embodiments, "both indoor and outdoor temperatures fall within the second temperature range, and the range hood module is in a non-standby state," specifically including:

[0145] When the range hood module is in either low or medium operating mode, if the outdoor temperature is lower than the indoor temperature, the cooling module will operate in low cooling mode; if the outdoor temperature is equal to or greater than the indoor temperature, the cooling module will operate in medium cooling mode. When the range hood module is in low operating mode, the cooling module can maintain the indoor temperature; when the range hood module is in medium operating mode, the cooling module can both cool the indoor temperature and handle the small amount of heat generated by the cooktop area.

[0146] When the range hood module is in high-level operation, if the outdoor temperature is lower than the indoor temperature, the cooling module will operate in medium-level cooling mode; if the outdoor temperature is greater than or equal to the indoor temperature, the cooling module will operate in high-level cooling mode. When the range hood module is in high-level operation, the cooling module can both cool the indoor temperature and handle the increased heat from the cooktop area.

[0147] In an optional embodiment, the refrigeration module further includes a heat exhaust fan 240 and a circulating fan 250; the circulating fan 250 is disposed in the first cavity 410 and is configured to cause the fluid in the first cavity 410 to flow out toward the cold air outlet 260; 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.

[0148] When the cooling module is off, both the exhaust fan 240 and the circulating fan 250 are off. 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 on. The fan speed of the exhaust fan 240 in low cooling mode is lower than that in medium cooling mode. The fan speed of the exhaust fan 240 in medium cooling mode is lower than that in high cooling mode. The fan speed of the circulating fan 250 in low cooling mode is lower than that in medium cooling mode. The fan speed of the circulating fan 250 in medium cooling mode is lower than that in high cooling mode.

[0149] In the optional embodiment, when the range hood module is in standby mode, the range hood fan 130 is in the off 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 the on state; the fan speed of the range hood fan 130 in the low mode is lower than the fan speed of the range hood fan 130 in the medium mode; the fan speed of the range hood fan 130 in the medium mode is lower than the fan speed of the range hood fan 130 in the high mode.

[0150] In the optional scheme of this embodiment, when the fresh air module is in the off state, the fresh air fan 310 is in the off state; when the fresh air module is in either the low-speed fresh air mode or the high-speed fresh air mode, the fresh air fan 310 is in the on state; the wind speed of the fresh air fan 310 in the low-speed fresh air mode is less than the wind speed of the fresh air fan 310 in the high-speed fresh air mode.

[0151] See Figure 9 and Figure 10As 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:

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.
