Abstract

A range hood with a leak-proof sealing structure includes a body, a fan unit, and a sealing gasket. The body includes an outer shell assembly and a middle frame assembly. The fan unit is mounted on the body and includes a fan box and at least one fan, with the fan housed within the fan box. The sealing gasket is disposed between the middle frame assembly and the fan box. The sealing gasket has a gasket body, an extension, and at least one arc-shaped sealing portion. The extension is connected to one side of the gasket body, extends upward, and protrudes beyond the top side of the gasket body. The arc-shaped sealing portion is located on the bottom side of the gasket body, and its cross-section is arc-shaped. The gasket body, the middle frame assembly, and the fan box are locked and fixed together by multiple locking elements. The gasket body is located between the top side of the middle frame assembly and the bottom side of the fan box. The extension and the arc-shaped sealing portion are located outside the locking elements. The extension is located outside the fan box, and the arc-shaped sealing portion contacts the top side of the middle frame assembly. This achieves a better leak-proof sealing effect.

Claims

1. A range hood with a leak-proof sealing structure, comprising: A body comprising an outer shell assembly and a middle frame assembly, the outer shell assembly being disposed above the middle frame assembly and connected to it; a fan assembly disposed on the body, the fan assembly having a wind box and at least one fan, the at least one fan being disposed within the wind box; and a sealing gasket, the sealing gasket being an elastomer, the sealing gasket having a gasket body, an extension portion and at least one arc-shaped sealing portion, the gasket body being frame-shaped, the extension portion being connected to one side of the gasket body and extending upward, the extension portion protruding from the top side of the gasket body and extending along the gasket body in a frame-shaped manner, the at least one arc-shaped sealing portion being disposed on the bottom side of the gasket body, the at least one arc-shaped sealing portion extending along the gasket body in a frame-shaped manner, and the cross-section of the at least one arc-shaped sealing portion being arc-shaped; The gasket body, the middle frame plate assembly, and the air box are locked and fixed together by a plurality of locking elements. The gasket body is disposed between the top side of the middle frame plate assembly and the bottom side of the air box. The extension and the arc sealing part are located outside the plurality of locking elements. The extension is located outside the air box. The at least one arc sealing part contacts the top side of the middle frame plate assembly.

2. The range hood with a leak-proof sealing structure as described in claim 1, wherein, The sealing gasket is a rubber gasket.

3. The range hood with a leak-proof sealing structure as described in claim 1, wherein, The sealing gasket has a Shore hardness of 60 to 70 degrees.

4. The range hood with a leak-proof sealing structure as described in claim 3, wherein, The sealing gasket has a Shore hardness of 65.
