Meanwhile, cooking oil smoke is generated by the oil smoke air inlet 12 through the first fan module 11 to be sucked into the public air duct through the first fan module 11 through power generated by the first fan module 11, negative pressure is formed below the first fan module 11, and due to the negative pressure formed below the first fan module 11 in the range hood body 1, the influence of the oil smoke on the radiating fins is avoided, so that the radiating fins cannot be influenced by the oil smoke and performance of the radiating fins is reduced.
As shown in fig. 4, the fan module 24 includes a cross flow fan installed at an air outlet of the cool air duct 22.
Thus, by installing the cross-flow fan at the air outlet of the cold air duct 22, the cool air generated by the cold end 236 can be blown out of the air outlet of the cold air duct 22 to the front of the people in the kitchen.
