[0054] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] Please refer to Figures 1-7 This embodiment provides a kitchen appliance, including:

[0056] The housing 400 includes a fume extraction channel 430, a fume inlet 110 and a fume outlet 120 connected to the fume extraction channel, and further includes a first cavity 410 and a second cavity 420 isolated from each other. In this embodiment, the fume extraction channel 430, the first cavity 410 and the second cavity 420 are isolated from each other. The specific arrangement of the fume extraction channel 430, the first cavity 410 and the second cavity 420 within the housing 400 can be determined according to actual conditions. For example, the first cavity 410 and the second cavity 420 may be located at the front of the housing 400, part of the fume extraction channel 430 may be located below the first cavity 410 and / or the second cavity 420, and part of the fume extraction channel 430 may be located behind the first cavity 410 and / or the second cavity 420. Here, A1 and / or A2 represent: only A1, or only A2, or A1 and A2.

[0057] The heat exchange structure includes an evaporator 210 and a condenser 220. The evaporator 210 is located in the first cavity 410 and is used to reduce the temperature of the first cavity 410. The condenser 220 is located in the second cavity 420. The evaporator 210 and the condenser 220 are connected to allow refrigerant to circulate.

[0058] The housing 400 also includes a condenser inlet 221, an exhaust outlet 241, and a supply outlet 260 for supplying gas to the room. The supply outlet 260 is connected to the first cavity 410, meaning that gas in the first cavity 410 flows out through the supply outlet 260. Both the condenser inlet 221 and the exhaust outlet 241 are connected to the second cavity 420, meaning that gas enters the second cavity 420 from the condenser inlet 221 and flows out of the second cavity 420 from the exhaust outlet 241.

[0059] The fresh air structure is located inside the housing 400 and has a fresh air inlet 311 that connects to the outside. The air outlet of the fresh air structure is connected to the air inlet channel of the evaporator 210, and the air outlet of the evaporator 210 is connected to the first cavity 410. Along the airflow direction, the air outlet of the fresh air structure, the evaporator 210, the first cavity 410 and the air outlet 260 are arranged in sequence. That is to say, the air intake of the evaporator 210 comes from the fresh air inlet 311 that connects to the outside. After being cooled by heat exchange in the evaporator 210, it is blown into the kitchen room through the first cavity 410 and the air outlet 260 in sequence.

[0060] The kitchen appliance described in this embodiment includes a fume extraction duct 430, a heat exchange structure, and a fresh air structure, integrating the range hood, refrigeration, and fresh air into one unit. This effectively improves the ease of installation, and its compact structure reduces space occupation, making full use of the kitchen's usable space. The air outlet of the fresh air structure is connected to the air inlet of the evaporator 210. The air outlet of the fresh air structure, the evaporator 210, the first cavity 410, and the air outlet 260 are arranged sequentially along the airflow direction, providing fresh cool air to the kitchen, increasing the oxygen content in the kitchen, and effectively improving the air quality. It also effectively avoids the problem of residual fumes in the kitchen affecting the heat exchange efficiency of the evaporator 210.

[0061] See Figures 1-7 As shown, in the optional embodiment, the air outlet 260 includes a first air outlet 261 and a second air outlet 262; the second air outlet 262 is an air curtain outlet, and the first air outlet 261 is located above the second air outlet 262. In this embodiment, the first air outlet 261 can introduce fresh cold air into the kitchen, which can effectively reduce the temperature in the kitchen and increase the oxygen content in the enclosed room; the second air outlet 262 is an air curtain outlet, which can form an air curtain during cooking, which can effectively increase the oxygen content in the stove area, cool the stove area, cool the user's body, and reduce the flow speed of oil fumes due to the cold, thereby effectively reducing the probability of oil fume escape. In the prior art, air curtain range hoods draw air from the kitchen space for air curtain delivery, which may lead to the diffused airflow carrying oil fumes being reintroduced into the air curtain structure and blown out, thus easily causing secondary oil fume diffusion. The kitchen appliance described in this embodiment effectively improves the problem of secondary oil fume diffusion.

[0062] In an optional embodiment, the housing 400 is rotatably connected to a first air guide structure 440 that blocks the first air outlet 261. The first air guide structure 440 is configured to guide the fluid from the first air outlet 261 to flow upward and / or downward. The first air guide structure 440 is used to guide the direction of the airflow from the first air outlet 261.

[0063] In an optional embodiment, the first air guiding structure 440 includes an air guiding plate or air guiding louvers, or other air guiding structures.

[0064] In an optional embodiment, the housing 400 is rotatably connected to a second air guide structure that blocks the second air outlet 262. The second air guide structure is configured to guide the fluid from the second air outlet 262 downwards. The second air guide structure facilitates the guidance of the airflow direction from the second air outlet 262.

[0065] In an optional embodiment, the number of second air outlets 262 can be one, for example, the second air outlet 262 can be disposed on the front panel of the housing 400; the number of second air outlets 262 can also be two; for example, each second air outlet 262 can be disposed on the front panel of the housing 400, or each second air outlet 262 can be disposed on the front panel and side wall of the housing 400; wherein the front panel and side wall of the housing 400 are adjacent. For example, the second air outlet 262 is L-shaped, and the second air outlet 262 can be disposed on the front panel and side wall of the housing 400.

[0066] In an optional embodiment, the second air outlet 262 may be straight, curved, or have other shapes.

[0067] In the optional embodiments of this invention, when there is only one second air outlet 262, the second air outlet 262 is in the shape of a door, a U, or other shapes.

[0068] In the optional embodiment, when there are two second air outlets 262, the second air outlets 262 are L-shaped or other shapes.

[0069] See Figures 1-6 As shown, in an optional embodiment, the housing 400 is rotatably connected to a baffle plate 460 that blocks the fume inlet 110. The baffle plate 460 improves the aesthetics of the housing 400, and when it is necessary to extract fumes, the baffle plate 460 can be opened to allow the fumes to be discharged from the fume inlet 110 into the kitchen. The baffle plate 460 and its rotating structure in this embodiment can adopt existing structures.

[0070] Optionally, the fume outlet 120 is located on the top panel of the housing 400; the fume inlet 110 is located on the front panel of the housing 400.

[0071] Optionally, the second air guide structure is disposed inside the housing 400 and above the smoke baffle 460. By disposing of the second air guide structure inside the housing 400, the aesthetics of the housing 400 can be improved; by placing the second air guide structure above the smoke baffle 460, the air curtain guided by the second air guide structure from the second air outlet 262 can better prevent the spread of oil fumes.

[0072] See Figures 1-7 As shown, in an optional embodiment, the housing 400 is provided with an evaporator air inlet 211 for indoor air intake, and the evaporator air inlet 211 is connected to the air intake channel of the evaporator 210; a first electrically controlled valve 213 is provided on the pipeline between the evaporator air inlet 211 and the air intake channel of the evaporator 210; a second electrically controlled valve 313 is provided on the pipeline between the air outlet of the fresh air structure and the air intake channel of the evaporator 210. The first electrically controlled valve 213 electrically controls the opening and closing of the pipeline between the evaporator air inlet 211 and the evaporator 210; the second electrically controlled valve 313 electrically controls the opening and closing of the pipeline between the fresh air structure and the evaporator 210.

[0073] Optionally, the evaporator air inlet 211 is located on the top panel of the housing 400, or the evaporator air inlet 211 is located at other positions in the housing 400.

[0074] The kitchen appliance described in this embodiment is connected to the air inlet channel of the evaporator 210 through the air outlet of the fresh air structure. The evaporator air inlet 211 is also connected to the air inlet channel of the evaporator 210, so that mixed air can be input into the evaporator 210. That is, the fresh air of the fresh air structure is mixed with the indoor air from the evaporator air inlet 211 to form mixed air. For example, when the evaporator 210 is in operation, such as in summer, the first electrically controlled valve 213 is closed and the second electrically controlled valve 313 is open. Fresh air from the fresh air structure, after being cooled by heat exchange in the evaporator 210, is blown into the kitchen room through the first cavity 410 and the air outlet 260, or output from the first air outlet 261 and / or the second air outlet 262. The first air outlet 261 can introduce fresh cold air into the kitchen room, which can effectively reduce the temperature in the kitchen room and increase the oxygen content in the enclosed room. The second air outlet 262 can form an air curtain during cooking, which can effectively increase the oxygen content in the stove area, cool the stove area, cool the user's body, and reduce the flow speed of oil fumes when they encounter cold, thereby effectively reducing the chance of oil fumes escaping. For example, when the evaporator 210 is not in operation, such as in winter, both the first and second electrically controlled valves 213 and 313 are open. The fresh air from the fresh air structure mixes with the indoor air from the evaporator air inlet 211 to form a mixed airflow that is blown into the kitchen. The mixed airflow can be output from the first air outlet 261 and / or the second air outlet 262, allowing the first air outlet 261 and / or the second air outlet 262 to input the mixed airflow 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.

[0075] See Figures 1-7 As shown, in an optional embodiment, the housing 400 is further provided with a fresh air supply port 312 for supplying gas to the room, and the fresh air supply port 312 is connected to the air outlet of the fresh air structure; a third electrically controlled valve 314 is provided on the pipeline between the fresh air supply port 312 and the air outlet of the fresh air structure. Through the fresh air supply port 312 and the third electrically controlled valve 314, fresh air can be separately supplied to the kitchen room to increase the oxygen content in the kitchen room.

[0076] See Figure 6 As shown, optionally, the housing 400 is connected to a filter structure at the evaporation air inlet 211; by connecting the filter structure to the evaporation air inlet 211, foreign objects such as dust and insects can be prevented from entering the evaporation air inlet 211.

[0077] See Figure 6 As shown, optionally, the housing 400 is connected to a filter structure at the condenser air inlet 221; by connecting the filter structure to the condenser air inlet 221, foreign objects such as dust and insects are prevented from entering the condenser air inlet 221.

[0078] Optionally, the housing 400 is connected to a filter structure at the fresh air inlet 311; by connecting the filter structure to the fresh air inlet 311, foreign objects such as dust and insects are prevented from entering the fresh air inlet 311.

[0079] See Figures 1-7 As shown, in the optional embodiment, the heat exchange structure further includes a compressor 230, a heat exhaust fan 240, and a circulating fan 250. The evaporator 210, condenser 220, and compressor 230 form a cooling circulation loop. The circulating fan 250 is disposed in the first cavity 410 and configured to drive the gas in the first cavity 410 to be output from the air outlet 260. The circulating fan 250 helps to output the air in the first cavity 410 from the air outlet 260. For example, the cold air cooled by the evaporator 210 in the first cavity 410 can be delivered to the kitchen room from the air outlet 260, which can reduce the temperature in the kitchen room.

[0080] Compressor 230 and exhaust fan 240 are both located in the second cavity 420. Along the airflow direction, the condenser inlet 221, condenser 220, second cavity 420, exhaust fan 240, and exhaust outlet 241 are sequentially connected. That is, the air outlet of condenser 220 and the air inlet of exhaust fan 240 are both connected to the second cavity 420, the air inlet of condenser 220 is connected to the condenser inlet 221, and the air outlet of exhaust fan 240 is connected to the exhaust outlet 241. The exhaust fan 240 accelerates the discharge of gas from the second cavity 420 through the exhaust outlet 241.

[0081] Optionally, the fresh air structure includes a fresh air fan 310 disposed in the first cavity 410; the fresh air fan 310 is configured to drive fresh air from the fresh air inlet 311 to the air outlet of the fresh air structure, that is, the fresh air fan 310 can drive fresh air from the fresh air inlet 311 to the air inlet channel of the evaporator 210, or it can drive fresh air from the fresh air inlet 311 to the fresh air outlet 312. The fresh air fan 310 accelerates the flow of fresh air from the fresh air inlet 311 to the air outlet of the fresh air structure.

[0082] Optionally, the housing 400 is connected to a range hood fan 130 located within the fume extraction duct 430. The range hood fan 130 is configured to drive the fumes from the fume inlet 110 to the fume outlet 120. The range hood fan 130 facilitates the flow of fumes from the fume inlet 110 to the fume outlet 120.

[0083] In an optional embodiment, part of the exhaust duct of the range hood fan 130 passes through the first cavity 410. When the evaporator 210 in the first cavity 410 is in operation, the oil fumes in the exhaust 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.

[0084] 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.

[0085] In an optional embodiment, the fresh air inlet 311 is located on the top panel of the housing 400, or at other locations within the housing 400.

[0086] In an optional embodiment, the condenser air inlet 221 and the exhaust air outlet 241 are both located on the top panel of the housing 400, or at other locations on the housing 400.

[0087] In an optional embodiment, the air outlet 260 is located on the front panel of the housing 400, or at other locations on the housing 400.
