[0032] Preferably, the cold air chamber 110 is provided with an air inlet, which is arranged at the air inlet position of the first wind turbine unit 200 and communicates with the outside of the machine body 100, so as to ensure smooth air inlet of the first wind turbine unit 200; an oil fume filter screen 108 is arranged at the air inlet.

[0033] Preferably, the machine body 100 is provided with a water storage box 107 connected with the cold air chamber 110 by a water pipe; the condensed water generated by the evaporator 300 flows into the water storage box 107 through the water pipe; the water storage box 107 can be pulled out to pour out the water; the water storage box 107 can store 3-4L of condensed water; the user can pour out the water in the water storage box once a week.

[0034] Preferably, the cold air outlet 105 is provided with a swing blade 104 capable of rotating, which facilitates the adjustment of the cold air direction.

[0035] In practice: When the range hood is in use, the compressor unit 600 works, and the cold air generated by the evaporator 300 is blown into the cold air duct 800 through the first fan unit 200, and then blown out from the cold air outlet 105, which lowers the kitchen temperature and makes people more comfortable when cooking. In addition, the heat generated by the condenser 400 is extracted by the second fan unit 700 in time, which prevents the heat from spreading in the range hood.

[0036] Example 2: Figures 3-6 As shown, based on the structure of Embodiment 1 above, in order to facilitate cleaning of the second wind turbine unit 700 and ensure the air suction effect of the second wind turbine unit 700, this embodiment installs a cleaning mechanism 500 inside the casing 101 for cleaning the second wind turbine unit 700. The cleaning mechanism 500 is located on the side of the air inlet of the second wind turbine unit 700. The cleaning mechanism 500 includes a fixing frame 501 and a water pump 502 fixedly installed inside the fixing frame 501. The fixing frame 501 is fixedly connected to the inner wall of the casing 101. The output end of the water pump 502 is connected to a water outlet pipe 504, and the end of the water outlet pipe 504 is rotatably and sealingly connected to a water spray head 505, which is located inside the air inlet of the second wind turbine unit 700. The input end of the water pump 502 is connected to... There is an inlet pipe 503, one end of which is connected to the water storage box 107. The water pump 502 can extract the condensate in the water storage box 107, which saves water and solves the problem of where to dispose of the condensate. Before turning on the cleaning mechanism 500, it is necessary to ensure that there is enough water in the water storage box 107. The water pump 502 sprays water onto the impeller of the second wind turbine unit 700 through the spray head 505 to clean the impeller and inner wall. The high-temperature airflow generated by the condenser 400 is drawn into the second wind turbine unit 700. The high-temperature airflow can heat the water mist sprayed by the spray head 505, increase the water temperature, and facilitate better melting of the oil stains inside the second wind turbine unit 700 to achieve a better cleaning effect. In addition, a check valve 507 is installed on the inlet pipe 503 to prevent the condensate from flowing back.

[0037] Preferably, the spray head 505 has a plurality of obliquely arranged spray holes 506 evenly distributed on its circumference. The spray holes 506 spray liquid in the form of water mist, which increases the spray area. When the spray holes 506 spray water, they drive the spray head 505 to rotate automatically, so that the spray head 505 can spray the impeller of the second wind turbine unit 700.

[0038] Preferably, the bottom of the second wind turbine unit 700 is connected to a drain pipe 106, and the end of the drain pipe 106 is connected to an oil collection tray 109. The wastewater after cleaning flows into the oil collection tray 109 through the drain pipe 106. After each cleaning, the wastewater in the oil collection tray 109 needs to be poured out. Since it needs to receive wastewater, the size of the oil collection tray 109 in this embodiment is much larger than that of the oil collection trays of range hoods on the market. The water storage capacity of the oil collection tray 109 is about 2L.

[0039] In the embodiment, when the cleaning mechanism 500 is turned on, the range hood is started at the same time, the water pump 502 is used to pump out the condensed water in the water storage box 107, and then the water is sprayed on the impeller of the second wind turbine set 700 through the water spraying head 505 to clean the impeller and the inner wall. At the same time, the high-temperature gas flow generated by the condenser 400 can heat the water mist sprayed by the water spraying head 505 when the high-temperature gas flow is sucked into the second wind turbine set 700, so as to improve the temperature of the water, facilitate the better melting of the oil stains in the second wind turbine set 700, and achieve a better cleaning effect. After cleaning, the waste water flows into the oil collection disc 109 through the drain pipe 106, and finally the waste water is poured out. It should be noted that in the embodiment, the cleaning mechanism 500 is turned on after the refrigeration unit is operated for at least 4-5 minutes (for example, after cooking), so as to heat the water mist sprayed by the water spraying head 505 by the high-temperature gas flow generated by the condenser 400, so as to achieve a better cleaning effect. In the embodiment, the cleaning mechanism 500 fully utilizes the condensed water and the high-temperature gas flow generated by the refrigeration unit to clean the second wind turbine set 700, which not only saves resources, but also facilitates the cleaning of the inside of the range hood.
