Optionally, the fresh air module includes a fresh air fan 310 disposed in the first cavity 410; the air inlet channel of the fresh air fan 310 is connected to the fresh air inlet 311, and the air outlet channel of the fresh air fan 310 is the air outlet channel of the fresh air module; that is, the air outlet channel of the fresh air fan 310 is connected to the first cavity 410; the fresh air fan 310 is electrically connected to the control module to facilitate automatic control of the fresh air fan 310.

[0093] 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 corresponding stove of the kitchen appliance, and according to the difference between the outdoor temperature and the indoor temperature and the working mode of the range hood module, correspondingly control the operation mode of the fresh air module, the operation mode of the first air supply port 312, the operation mode of the second air curtain air supply port 313 and the operation mode of the refrigeration module in the open state. 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.

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.

[0096] 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 312 and the second air curtain air outlet 313 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 first air outlet 312 and / or the second air curtain air outlet 313; the first air outlet 312 can reduce the temperature in the kitchen to a certain extent while inputting fresh air into the kitchen to increase the indoor oxygen content; the second air curtain air outlet 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 fresh air provided by the fresh air module can be buffered in the first cavity 410, for example, mixed with the indoor air to increase temperature and form mixed air, and the mixed air can be output from the first air supply port 312 and / or the second wind curtain air supply port 313, so that the first air supply port 312 and / or the second wind curtain air supply port 313 can input the mixed air with 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.

[0097] 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 into the kitchen during cooking, effectively improving the cooking experience. Specifically, the evaporator 210 of the refrigeration module is disposed in the first cavity 410 of the body 400, and the condenser 220 and the compressor 230 of the refrigeration module are both disposed 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 an indoor unit and an outdoor unit, and the structure is relatively compact and the installation is relatively convenient. By connecting the air outlet channel of the fresh air module with the first cavity 410, and providing the first air supply port 312 and the second air curtain air supply port 313 connected with the first cavity 410 respectively on the body 400, it is possible to determine whether the refrigeration module is turned on according to the indoor and outdoor temperature conditions. For example, when the refrigeration module is turned on in summer, the cold air and the fresh air are mixed in the first cavity 410 and output from the first air supply port 312 or the second air curtain air supply port 313; the mixed gas is transported to the kitchen room through the first air supply port 312 to reduce the air temperature in the kitchen room to a certain extent and increase the oxygen content in the kitchen room; the mixed gas air curtain is output through the second air curtain air supply port 313, 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.

[0098] The kitchen appliance of this embodiment adopts the condenser 220 for cooling, which has higher cooling efficiency and better cooling effect than the semiconductor cooling technology.
