Range hood and air inlet ring thereof

Abstract

The invention provides a range hood and an air inlet ring thereof. A first installation plane and a second installation plane of the air inlet ring are not arranged in parallel, but arranged with a first included angle which is an acute angle. The first installation plane and the second installation plane are formed by edges on two sides of an outer ring, wherein the edges are folded outwards. Connection structures are respectively arranged on the first installation plane and the second installation plane. A first fixing structure is arranged on the air inlet ring. With the air inlet ring provided by the invention, oil smoke absorption effect of the range hood is improved, a limitation on a spiral case installation angle is eliminated, the connection between the air inlet ring and the range hood is reinforced, and a plurality of fixing manners are provided, such that the air inlet ring can easily be detached. The invention also provides a range hood with the air inlet ring. With the air inlet ring, the oil smoke absorption effect is improved.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood and an air inlet ring thereof. Background technique [0002] Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed on the top of the stove in the kitchen, and can quickly take away the waste burned by the stove and the oily fumes harmful to the human body produced during the cooking process, and discharge them to the outside, reduce indoor pollution, purify the indoor air, and have the safety guarantee function of anti-virus and explosion-proof . [0003] At present, range hoods can be roughly divided into three types: one is Chinese-style range hoods, the other is direct-suction range hoods, and the third is side-suction range hoods. [0004] Chinese-style range hoods are mainly divided into old-fashioned shallow and deep-suction range hoods, which generally refer to ordinary exhaust fans that direc...

AI Technical Summary

Problems solved by technology

For side suction range hoods, there is a large inclination angle between the plane of the smoke collecting chamber and the plane where the cooker is located, but the plane where the air inlet hole of the volute is located is still parallel to the plane of the smoke collecting chamber, and the volute enters The plane where the air hole is located must also have a large inclination angle with the plane where the cooker is located, so the air outlet of the volute will also be inclined at an angle, and it cannot be connected vertically with the air duct

This not only restricts the installation of the volute, but also affects the fume exhaust effect of the range hood
