[0029] In order to solve the problems of fresh air, high temperature and oil smoke in the kitchen during cooking, this embodiment provides a kitchen appliance and a control method and related devices thereof, wherein the kitchen appliance integrates a range hood module, a refrigeration module and a fresh air module, and can control smoke, cool and introduce fresh air for the kitchen during cooking, thereby effectively improving the cooking experience. The kitchen appliance may be, for example, a range hood or a similar appliance, such as an ultra-thin range hood.

[0030] See also Figure 1-Figure 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 which 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 in the body 400 can be determined according to actual conditions, for example, the first cavity 410 and the second cavity 420 are arranged in front of the body 400, part of the third cavity 430 is arranged below the first cavity 410 and / or the second cavity 420, and part of the third cavity 430 is arranged behind the first cavity 410 and / or the second cavity 420. Herein, A1 and / or A2 means: only A1, or only A2, or A1 and A2.

[0031] The refrigeration module includes an evaporator 210, a condenser 220 and a compressor 230 for forming a cooling cycle; the evaporator 210 is arranged in the first cavity 410, and the evaporator 210 is configured to reduce the temperature in the first cavity 410; the condenser 220 and the compressor 230 are both arranged in the second cavity 420; optionally, the evaporation air inlet 211 of the evaporator 210 is arranged on the body 400, and the evaporation air outlet of the evaporator 210 is connected to the first cavity 410. Optionally, the condensation air inlet 221 of the condenser 220 is arranged on the body 400, the air outlet channel of the condenser 220 is connected to the second cavity 420, and the body 400 is provided with a heat exhaust port 241 connected to the second cavity 420. The gas in the kitchen flows into the condenser 220 from the condensation air inlet 221, is heated after heat exchange with the condenser 220 in the working state, and flows to the second cavity 420, and then is discharged to the outside through the heat exhaust port 241.

[0032] A circulation fan 250 is arranged in the first cavity 410; the fresh air module includes a fresh air inlet 311 arranged on the body 400 and connected to the outdoors, and the air outlet channel of the fresh air module is connected to the inlet of the circulation fan 250, so that the fresh air of the fresh air module can be mixed with the indoor circulating air of the circulation fan 250 to form a mixed air.

[0033] The machine body 400 is provided with a mixed air supply port 260, and the machine body 400 is pivotally connected with an air guide structure 440 at the mixed air supply port 260. When the air guide structure 440 swings, it can guide the fluid to flow upward and / or downward. The circulating fan 250 is configured to make the fluid in the first cavity 410 flow out from the mixed air supply port 260. Optionally, the mixed air supply port 260 is configured as a first air supply port that can guide the fluid to flow upward and / or a second air supply port that guides the fluid to flow downward when the air guide structure 440 swings, and the airflow output from the second air supply port can form an air curtain. The circulation fan 250 helps to output the air in the first cavity 410 from the mixed air supply port 260, that is, from the first air supply port and / or the second air supply port. For example, the mixed air obtained by mixing the cold air cooled by the evaporator 210 in the first cavity 410 with the fresh air is delivered to the kitchen from the first air supply port, which can reduce the temperature in the kitchen and increase the oxygen content in the kitchen. The mixed air is delivered to the vicinity of the stove from the second air supply port, which can form a mixed gas wind curtain, assist the range hood module in smoke control, effectively reduce the escape of oil smoke, and effectively increase the oxygen content in the stove area.

[0034] The range hood module is disposed in the third cavity 430; optionally, the range hood module includes a range hood fan 130 disposed in the third cavity 430; the range hood fan 130 is electrically connected to the control module to automatically control the range hood fan 130. In this embodiment, the third cavity 430 serves as an independent channel, and the range hood module can discharge oil smoke into the common kitchen flue.

[0035] The range hood module, the refrigeration module, the fresh air module, the circulating fan 250 and the air guide structure 440 are electrically connected to the control module respectively; the control module is configured to control the opening and closing of the refrigeration module according to the outdoor temperature and indoor temperature of the kitchen area where the kitchen appliance is located; and the control module is also configured to control the working mode of the range hood module according to the cooking state of the kitchen appliance corresponding to the stove, and according to the difference between the outdoor temperature and the indoor temperature and the working 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 refrigeration module in the turned-on state are correspondingly controlled. For the specific working principle and control method of the control module, reference can be made to the kitchen appliance control method and kitchen appliance control device described below, which will not be repeated here.

[0036] 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, the processor and the communication module are electrically connected to each other 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. Among them, the memory is used to store programs or data; the memory can be but not limited to a random access memory (RAM), a read-only memory (ROM), a programmable read-only memory (PROM), an erasable read-only memory (EPROM), an electrically erasable read-only memory (EEPROM), etc. The processor is used to read / write the data or program stored in the memory and perform corresponding functions. The communication module is used to establish a communication connection between the control module and other communication terminals through a network, and is used to send and receive data through the network.

[0037] In this embodiment, after the kitchen appliance is installed in the kitchen, the gas in the kitchen flows into the evaporator 210 from the evaporation air inlet 211, flows to the first cavity 410 after being cooled by the evaporator 210 in the working state, and can be mixed with the fresh air of the fresh air module in the first cavity 410. For example, driven by the fresh air fan 310, the outdoor fresh air flows into the first cavity 410 from the fresh air inlet 311, and flows to the mixed air outlet 260 after being mixed in the first cavity 410. Among them, the mixed air outlet 260 can input the mixed air of fresh air and cold air into the kitchen room, effectively increasing the oxygen content in the closed room, and can also reduce the indoor temperature to a certain extent; the second air outlet of the mixed air outlet 260 can form an air curtain during cooking, which can not only effectively increase the oxygen content in the stove area, but also assist the smoke control of the range hood module, and effectively reduce the probability of oil smoke escaping. In the prior art, the air curtain hood absorbs air from the kitchen space to deliver air through the air curtain, which is likely to cause the diffused airflow with oil smoke to be introduced into the air curtain structure again and blown out, thus easily causing secondary oil smoke diffusion. The kitchen appliance described in this embodiment effectively improves the problem of secondary oil smoke diffusion.

[0038] The kitchen appliance described in this embodiment is connected to the first cavity 410 through the air outlet channel of the fresh air module, and the evaporator 210 is configured to reduce the temperature in the first cavity 410, so that the first air outlet and the second air outlet connected to the first cavity 410 can output mixed air with a lower temperature. For example, when the evaporator 210 is in a working state, such as in summer, the cold air in the first cavity 410 is mixed with the fresh air to form a mixed air, and the mixed air with a relatively low temperature can be output from the top (such as the first air outlet) and / or the bottom (such as the second air outlet) according to the swing angle of the air guide structure 440. The first air outlet can input fresh air into the kitchen room to increase the indoor oxygen content and reduce the temperature in the kitchen room to a certain extent; the second air outlet outputs a relatively low temperature mixed air curtain when cooking, which not only effectively increases the oxygen content in the stove area, but also cools the stove area and the user's body temperature, and can also reduce the flow speed of the oil smoke when it encounters cold, thereby effectively reducing the probability of oil smoke escaping. For example, when the evaporator 210 is in a non-working state, 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 and heated to form mixed air. The mixed air can be output from the first air supply outlet and / or the second air supply outlet, so that the first air supply outlet and / or the second air supply outlet can input the mixed air with relatively mild temperature into the kitchen, effectively avoiding the direct input of outdoor cold air into the kitchen and causing discomfort to the user.

[0039] The kitchen appliance described in this embodiment integrates a range hood module, a refrigeration module and a fresh air module, which can control smoke, cool and introduce fresh air for the kitchen during cooking, effectively improving the cooking experience. Specifically, the evaporator 210 of the refrigeration module is arranged in the first cavity 410 of the body 400, and the condenser 220 and the compressor 230 of the refrigeration module are both arranged in the second cavity 420 of the body 400, that is, the refrigeration modules are all integrated in the body 400, and are no longer divided into indoor units and outdoor units. Its structure is relatively compact and installation is relatively convenient. By arranging a circulation fan 250 in the first cavity 410, the air outlet channel of the fresh air module is connected to the inlet of the circulation fan 250, and the circulation fan 250 is configured to make the fluid in the first cavity 410 flow out from the mixed air supply port 260, it can be determined whether the refrigeration module is turned on according to the indoor and outdoor temperature conditions, and whether the cold air is mixed with the fresh air to form a mixed air. For example, when the refrigeration module is turned on in summer, the cold air is mixed with the fresh air and output from the mixed air supply port 260; an air guide structure 440 is pivotally connected to the mixed air supply port 260 through the machine body 400, and the air guide structure 440 can guide the fluid to flow upward and / or downward when it swings, wherein the mixed air supply port 260 forms a first air supply port for outputting an upward air flow and a second air supply port for outputting a downward air flow when the air guide structure 440 swings, and the air flow output from the second air supply port can form an air curtain; the mixed gas is transported into the kitchen room through the first air supply port to reduce the air temperature in the kitchen room to a certain extent and increase the oxygen content in the kitchen room, and the mixed gas air curtain is output through the second air supply port, which can assist the range hood module in smoke control, effectively reduce the escape of oil smoke, and effectively increase the oxygen content in the stove area.

[0064] The following combination Fig. 9 and Fig.10 The kitchen appliance control method provided in this embodiment is described, and the kitchen appliance control method includes: Step S100, turning on the power of the kitchen appliance.

[0065] Step S200, obtaining the outdoor temperature of the kitchen appliance and the indoor temperature of the kitchen area; when the indoor temperature belongs to the first temperature range, the refrigeration module is kept in the off state; when the indoor temperature and the outdoor temperature belong to the second temperature range, the refrigeration module is turned on; for example, the first temperature range is greater than 10°C and less than 26°C, and the second temperature range is greater than or equal to 26°C; for another example, the first temperature range is greater than 10°C and less than 28°C, and the second temperature range is greater than or equal to 28°C; for another example, the first temperature range is greater than -1°C and less than 26°C, and the second temperature range is greater than or equal to 26°C. In this embodiment, the first temperature range and the second temperature range can be determined according to factors such as the ambient temperature of the kitchen appliance.

[0066] Step S300, obtain the cooking status of the stove corresponding to 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 refrigeration module in the turned-on state.

[0067] The kitchen appliance control method described in this embodiment can determine whether to turn on the refrigeration module based on the indoor and outdoor temperatures. When the indoor temperature and the outdoor temperature both belong to the second temperature range, the refrigeration module is turned on to lower the indoor temperature. The working mode of the range hood module is controlled according to the cooking state of the stove. According to the difference between the outdoor temperature and the indoor temperature and the working 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 refrigeration module in the turned-on state are controlled accordingly.

[0068] In some embodiments, the specific working modes of the range hood module may include, for example, standby state, range hood low gear, range hood medium gear, and range hood high gear. The range hood low gear is, for example, the gear at which the range hood is turned off after cooking; the range hood medium gear is, for example, the gear at which less oil smoke and less heat are generated, such as the gear at which the range hood is in steaming; the range hood high gear is, for example, the gear at which more oil smoke and more heat are generated, such as the gear at which the range hood is in frying, stir-frying, or deep-frying.

[0069] Optionally, when the air guide structure 440 swings to the first angle, the first air supply port is closed, the second air supply port is fully opened and outputs airflow downward; when the air guide structure 440 swings to the second angle, the first air supply port and the second air supply port are both partially covered, and the area covered by the first air supply port is smaller than the area covered by the second air supply port; when the air guide structure 440 swings to the third angle, the second air supply port is closed, the first air supply port is fully opened and outputs airflow upward. Optionally, when the air guide structure 440 swings to the second angle, 20% of the area of ​​the first air supply port is covered so that 80% of the area of ​​the first air supply port is opened, and 80% of the area of ​​the second air supply port is covered so that 20% of the area of ​​the second air supply port is opened; for example, the total airflow output from the mixed air supply port 260, wherein 80% of the total airflow is delivered from the first air supply port, and 20% of the total airflow is delivered from the second air supply port. In some embodiments, when the air guide structure 440 swings to the second angle, the covered area of ​​the first air supply outlet and the covered area of ​​the second air supply outlet can also be other values; for example, 30% of the area of ​​the first air supply outlet is covered so that 70% of the area of ​​the first air supply outlet is opened, and 70% of the area of ​​the second air supply outlet is covered so that 30% of the area of ​​the second air supply outlet is opened; for another example, 25% of the area of ​​the first air supply outlet is covered so that 75% of the area of ​​the first air supply outlet is opened, and 75% of the area of ​​the second air supply outlet is covered so that 25% of the area of ​​the second air supply outlet is opened, and the second air supply outlet is covered so that 25% of the area of ​​the second air supply outlet is opened, etc.

[0070] Optionally, when the working mode of the range hood module is in the standby state, the fresh air module maintains the closed state, and the first air outlet and the second air outlet are not supplying air, for example, the mixed air outlet 260 is in the closed state. Optionally, when the working mode of the range hood module is in the standby state, when the indoor temperature is within the first temperature range, for example, 10°C < indoor temperature < 26°C, the range hood module, the refrigeration module and the fresh air module are all in the closed state, such as Figure 5 As shown in the figure, when the working mode of the range hood module is in the standby state, when the indoor temperature and the outdoor temperature are both within the second temperature range, for example, when the indoor temperature is ≥26℃ and the outdoor temperature is ≥26℃, the range hood module and the fresh air module are both in the off state, and the cooling module is in the on state. Figure 6 As shown, optionally, when the working mode of the range hood module is in standby state, the fresh air module is in a closed state, the refrigeration module is in a weak gear state, and the air guide structure 440 guides air upward (at this time, the first air supply port is 100% open, the second air supply port is closed, and the air guide structure 440 swings to a third angle), and the cold air flows upward to cool down the kitchen. Since hot air rises and cold air falls, the upward diversion helps the cold air to cover the entire space, effectively preventing hot and cold stratification in the kitchen.

[0071] Optionally, when the working mode of the range hood module is in the middle gear, the fresh air module is controlled to operate and be in the fresh air low gear mode; when the indoor temperature is within the first temperature range, for example, 10°C < indoor temperature < 26°C, the refrigeration module is in a closed state, and the air guide structure 440 swings to a first angle, for example, the air guide structure 440 swings downward to close the first air supply port and fully open the second air supply port (that is, the second air supply port is 100% open), and the opened second air supply port can form a downward wind curtain; if the indoor temperature is within the first temperature range and 26°C > outdoor ≥ indoor temperature, the air guide structure 440 swings to the first angle, for example, the air guide structure 440 swings downward to close the first air supply port and open the second air supply port 100%, so that outdoor air that is higher than the room temperature can be introduced to improve indoor comfort. When both the indoor temperature and the outdoor temperature are within the second temperature range, for example, when the indoor temperature is ≥26°C and the outdoor temperature is ≥26°C, the refrigeration module is in the on state, and the air guide structure 440 swings to the second angle, for example, the air guide structure 440 swings so that the first air supply port is covered by 20% of its area, thereby forming an 80% area of ​​the first air supply port to be opened, and the second air supply port is covered by 80% of its area, thereby forming an 20% area of ​​the second air supply port to be opened; wherein, when the air guide structure 440 swings, the mixed air supply port 260 forms a first air supply port that outputs airflow upward and a second air supply port that outputs airflow downward; the airflow output from the second air supply port forms a wind curtain. If both the indoor temperature and the outdoor temperature are within the second temperature range, and 26°C≤outdoor<indoor temperature, the air guide structure 440 guides the air up and down at the same time so that 80% of the first air supply port is opened and 20% of the second air supply port is opened, and fresh air with a relatively low outdoor temperature can be introduced to assist in indoor cooling, and 20% of the second air supply port is opened to form a wind curtain, such as Figure 7 When the range hood is in the mid-range mode, the fresh air module operates in the low-range mode to prevent the air curtain from blowing away the oil smoke due to excessive air volume. The first air outlet is opened by 80% and directed upward to assist in cooling the room.

[0072] Optionally, when the working mode of the range hood module is in the high-speed range hood mode, the fresh air module is controlled to operate and be in the mid-speed fresh air mode; when the indoor temperature is within the first temperature range, for example, 10°C < indoor temperature < 26°C, the refrigeration module is in a closed state, and the air guide structure 440 swings to a first angle, for example, the air guide structure 440 swings downward to close the first air supply port and fully open the second air supply port (that is, the second air supply port is 100% open), and the opened second air supply port can form a downward wind curtain; if the indoor temperature is within the first temperature range, and 26°C > outdoor ≥ indoor temperature, the air guide structure 440 swings to the first angle, for example, the air guide structure 440 swings downward to close the first air supply port and open the second air supply port 100%, and the airflow output from the second air supply port can form a wind curtain, which can introduce outdoor air that is higher than the room temperature, thereby improving indoor comfort. When both the indoor temperature and the outdoor temperature are within the second temperature range, for example, when the indoor temperature is ≥26°C and the outdoor temperature is ≥26°C, the refrigeration module is in the on state, and the air guide structure 440 swings to the second angle, for example, the air guide structure 440 swings so that the first air supply port is covered by 20% of its area, thereby forming an 80% area of ​​the first air supply port to be opened, and the second air supply port is covered by 80% of its area, thereby forming an 20% area of ​​the second air supply port to be opened; wherein, when the air guide structure 440 swings, the mixed air supply port 260 forms a first air supply port that outputs airflow upward and a second air supply port that outputs airflow downward; the airflow output from the second air supply port forms a wind curtain. If both the indoor temperature and the outdoor temperature are within the second temperature range, and 26°C≤outdoor<indoor temperature, the air guide structure 440 guides the air up and down at the same time so that 80% of the first air supply port is opened and 20% of the second air supply port is opened, and fresh air with a relatively low outdoor temperature can be introduced to assist in indoor cooling, and 20% of the second air supply port is opened to form a wind curtain, such as Figure 7 When the range hood is in the mid-range mode, the fresh air module operates in the mid-range mode to prevent the air curtain from blowing away the oil smoke due to excessive air volume. 80% of the first air outlet is opened and directed upward to assist in cooling the room.

[0073] Optionally, when the working mode of the range hood module is in the low gear, the fresh air module is controlled to operate and be in the fresh air high gear mode; at the same time, the air guide structure 440 is swung to a third angle, for example, the air guide structure 440 is swung upward to fully open the first air supply port and close the second air supply port; by swinging the air guide structure 440 upward to fully open the first air supply port and close the second air supply port, the airflow can be directed upward to prevent the introduced fresh air from being immediately sucked away by the range hood, and the residual oil smoke airflow can be preferentially absorbed and discharged, thereby improving indoor comfort.
