The refrigeration range hood can realize all the functions of the range hood and the function of the air conditioner. For example, the Chinese utility model patent No. 202320059220.6 (authorization announcement No. CN 219222570U) discloses a refrigeration range hood. The fume extraction module of the refrigeration range hood includes a fan frame and a fume extraction fan.

The heat dissipation cavity is arranged outside the fan frame, and the condenser is installed inside the heat dissipation cavity. The heat dissipation fan is located outside the heat dissipation cavity and installed on the top of the heat dissipation cavity. The heat dissipation fan outlet faces the inside of the heat dissipation cavity, and the heat dissipation cavity has a heat dissipation outlet connected to the air inlet of the fume extraction fan. Although the heat of the condenser of the refrigeration-type range hood enters the range hood fan through the heat dissipation outlet and is then taken away by the range hood fan, the condenser is arranged outside the smoke exhaust passage, and no purification device is required, so the cost and maintenance rate are reduced. However, the air outlet of the heat dissipation fan is fluidly connected with the fan air inlet through the heat dissipation outlet on the fan frame, and the wind blown out of the heat dissipation fan outlet will interfere with the oil fume airflow at the fan air inlet, thereby affecting the oil fume extraction effect. In summary, the existing air-conditioning-type range hood needs to be further improved. Utility Model Content

[0023] The range hood fan 12 of this embodiment is a centrifugal fan. The range hood fan 12 is vertically arranged and the central axis of the impeller of the range hood fan 12 is perpendicular to the front of the range hood. The range hood fan 12 adopts a double air inlet structure. Figure 2 The direction indicated by the middle arrow B is the front, the front air inlet is the main air inlet 121, and the rear air inlet is the auxiliary air inlet 122. An air inlet cavity 13 is installed below the fan frame 11, and the air inlet cavity 13 has a smoke inlet 131, which is fluidly connected with the main air inlet 121 and the auxiliary air inlet 122. When the range hood is working, oil smoke enters the main air inlet 121 and the auxiliary air inlet 122 through the smoke inlet 131.

[0024] The heat dissipation fan 32 of this embodiment is located below the condenser 31, that is, along the air flow direction, the heat dissipation fan 32 is located downstream of the condenser 31. The heat dissipation fan 32 is also a centrifugal fan, and the central axis of the impeller of the heat dissipation fan 32 is arranged horizontally and perpendicular to the central axis of the impeller of the range fumes exhaust fan 12.

[0025] In addition, the air outlet end of the air volume transfer interface 33 has an air outlet facing the auxiliary air inlet 122, and the lower edge of the air outlet has an air guide piece 331 bent obliquely upward, and the hot air blown out of the air outlet of the air volume transfer interface 33 is guided to the inside of the range hood exhaust fan 12 through the air guide piece 331.
