[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 supply port 312 and a second air curtain supply port 313 disposed on the body 400 and connected to the air outlet channel of the fresh air module. The first fresh air supply port 312 is configured to supply air to the indoor environment, and the second air curtain supply port 313 is configured to form an air supply curtain in the stove area. Optionally, the fresh air module includes a fresh air fan 310 disposed in 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 the control module to facilitate automatic control of the fresh air fan 310.

[0098] 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.

[0099] The range hood module, the refrigeration module and the fresh air module 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. The control module controls 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, so as to control whether the gas in the first cavity 410 is mixed with the fresh air of the fresh air module. The control module controls the operation mode of the fresh air module and the operation mode of the refrigeration module in the open state according to the working mode of the range hood module. For the specific working principle and control method of the control module, please refer to the kitchen appliance control method and kitchen appliance control device 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, 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.

[0101] In this embodiment, after the kitchen appliance is installed in the kitchen, the gas in the kitchen, for example, 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 then outputs the cold air from the first cavity 410 through the cold air supply port 260. For example, 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. For another example, driven by the fresh air fan 310, outdoor fresh air flows in from the fresh air inlet 311 and flows to the first fresh air supply port 312 and / or the second air curtain supply port 313. Among them, the first fresh air supply port 312 inputs fresh air into the kitchen, effectively increasing the oxygen content in the closed room; the second air curtain supply port 313 can form an air curtain during cooking, which not only effectively increases the oxygen content in the stove area, but also assists the smoke control module of the range hood, effectively reducing the probability of oil smoke escaping. In the prior art, the air curtain range hood absorbs air from the kitchen indoor space for air curtain supply, which is very likely to cause the diffused airflow with oil smoke to be introduced into the air curtain structure again and blown out, which is easy to cause secondary oil smoke diffusion. The kitchen appliance described in this embodiment effectively improves the problem of secondary oil smoke diffusion.

[0102] The kitchen appliance described in this embodiment is connected to the first cavity 410 through the second air inlet 314, so that the fluid in the first cavity 410 can be injected into the fresh air duct to mix with the fresh air and form mixed air. For example, when the evaporator 210 is in working state, such as in summer, the cold air in the first cavity 410 is injected into the fresh air duct to cool the fresh air and form mixed air, and the mixed air with a relatively low temperature can be output from the first fresh air supply port 312 and / or the second air curtain supply port 313; the first fresh air supply port 312 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 curtain supply port 313 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 first cavity 410 circulates the air in the kitchen, and the air in the kitchen is injected into the fresh air duct to heat the fresh air and form mixed air. The mixed air can be output from the first fresh air supply port 312 and / or the second wind curtain supply port 313, so that the first fresh air supply port 312 and / or the second wind curtain supply port 313 can input the mixed air with a relatively mild temperature into the kitchen, thereby effectively avoiding the direct input of outdoor cold air into the kitchen and causing discomfort to the user.

[0103] 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.

Its structure is relatively compact and convenient to install. Through the second air curtain air supply port 313 of the fresh air module, an air curtain can be formed during cooking, which can assist the range hood module in controlling smoke and effectively reduce the escape of oil smoke; through the evaporator 210 configured to reduce the temperature in the first cavity 410, the second air inlet 314 of the fresh air module is connected to the first cavity 410, and cold air can be injected into the fresh air pipeline, which reduces the temperature of the fresh air to a certain extent, for example, it can effectively improve the cooking experience in summer. Cold air can be directly delivered through the cold air supply port 260 on the body 400 to effectively reduce the indoor temperature in the kitchen; fresh air can be directly delivered through the first fresh air supply port 312 on the body 400 to inject fresh air into the kitchen, which is beneficial to increase the oxygen in the kitchen.
