Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, in particular to a fan system and an integrated range hood. Background Art

[0002] There are various fan systems for integrated range hoods on the existing market. Basically, all fan systems are composed of a negative pressure box assembly, a volute assembly, and a duct assembly. Among them, the volute assembly is inside the negative pressure box assembly, and the negative pressure box assembly is above the duct assembly. When the motor in the volute assembly starts, oil fume flows into the negative pressure box, and then flows into the duct assembly through the volute assembly. There is a wind deflector in the duct assembly, which can adjust the air outlet direction according to the layout of different household kitchens. The oil fume can be discharged through the duct assembly according to the conduction direction of the wind deflector. Currently, for the duct systems on the market that can adjust the air outlet direction, the air outlets on both sides are generally the same. The side with air outlet is connected to the smoke pipe and conducted to the outside, and the other side is installed with an air outlet cover to prevent air leakage. The disadvantage of this is that the production cost is relatively high and it is difficult to seal the side without air outlet, which is prone to air leakage and leads to a decline in the performance of the fan system. Summary of the Utility Model

[0003] Based on the technical problems existing in the background art, the utility model provides a fan system and an integrated range hood, which effectively reduce the production cost and improve the sealing performance of the sealing end of the duct assembly at the same time.
