AI Technical Summary

Technical Problem

The air inlet and outlet duct directions of the existing desktop range hood are straight, resulting in limited suction effect of the range fume, especially the suction effect of the range hood on the side of the range hood.

Method used

Design a desktop range hood, its pumping structure includes shells, suction components and voting parts. The diversion is set up near the side of the suction component. There is a diversion surface. The diversion surface is discharged along the medium and gradually expands from the center to four weeks, so that the medium is discharged from the peripheral of the drainage. The design of the suction component and the diversion makes the medium discharge as smooth as possible during the diversion to avoid blocking, thereby improving the absorption effect.

Benefits of technology

By tilting the design and diversion design of the pumping structure, it improves the absorbing effect of the fuel fume on the side of the range hood, making the overall oil absorption effect of the range hood.

Abstract

The present utility model provides a tabletop range hood, comprising a base structure and a suction structure. The base structure is configured to be mounted on a tabletop. The suction structure is connected to the base structure, and is configured to face cookware to suction grease and fumes. The suction structure comprises: a housing internally provided with a first installation cavity; and a suction assembly and a flow guide member sequentially arranged in a suction direction. The suction assembly is located inside the first installation cavity, and the flow guide member is installed on the suction assembly. A flow guide surface is disposed on the side of the flow guide member close to the suction structure, and is configured to guide discharge of a medium, and in a medium discharge direction, the flow guide surface gradually expands outwards from the center so that the medium can be discharged from the outer periphery of the flow guide member. This structure enables grease and fumes on the periphery of the housing to move towards low air pressure areas on the flow guide member, thereby enabling suction of grease and fumes on the outer periphery of the suction structure, and improving suction performance.
