The top wall of the first casing 26 is provided with a first air inlet 30, when the range hood 100 is used for cooling, external air can be sucked from the first air inlet 30 and enters the first casing 26, and the air entering the first casing 26 exchanges heat with a low-temperature refrigerant in a pipeline of the evaporator 28 on the surface of the evaporator 28. Because the cold air discharged to the kitchen space by the range hood 100 has a sinking tendency, the air is introduced from the first air inlet 30 on the top wall of the first housing 26, so that the suction of the cold air can be reduced, and the refrigeration effect can be ensured.

The compressor 42 can compress the low-temperature and low-pressure refrigerant (gas) returned from the evaporator 28 into a high-temperature and high-pressure refrigerant (gas), and the refrigerant (gas) is condensed into a medium-temperature and high-pressure refrigerant (liquid) by the condenser 40, and the refrigerant (liquid) is throttled by the throttle valve and becomes a low-temperature and low-pressure refrigerant (liquid). The low-temperature and low-pressure refrigerant (liquid) is sent to the evaporator 28, absorbs heat in the evaporator 28, evaporates into a low-temperature and low-pressure refrigerant (gas), and is sent to the compressor 42 again, thereby completing the refrigeration cycle.

Therefore, the air outlet can be more uniform.

Specifically, in the illustrated embodiment, the flow diversion structure 48 is located within the transverse segment 36. One end of the transverse section 36 is connected with the longitudinal section 34, and the air outlet quantity of the transverse section 36 close to the longitudinal section 34 is more, and the air outlet quantity of the transverse section 36 far away from the longitudinal section 34 is less as the cold air entering the transverse section 36 through the longitudinal section 34 is transported in the transverse section 36.

The flow dividing structure 48 and the plurality of flow dividing members 50 positioned in the transverse section 36 may divide the space in the transverse section 36 to form a plurality of flow dividing channels 52, and the outlets of the plurality of flow dividing channels 52 are aligned in the direction of airflow such that the cold air flowing from the longitudinal section 34 into the transverse section 36 is divided by the interior of each flow dividing channel 52 into a plurality of sub-flows, and each sub-flow is transported in a separate flow dividing channel 52 until being discharged from the outlet of each flow dividing channel 52.
