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 its air inlet ring. Background technique [0002] Range hoods, also known as range hoods, are kitchen appliances that purify the kitchen environment. It is installed above the stove in the kitchen, and can quickly remove the waste from the stove and the harmful oil fume generated during the cooking process, and discharge it to the outside, reduce indoor pollution, purify indoor air, and have the effect of preventing poison and explosion protection. . [0003] At present, range hoods can be roughly divided into three types: one is a Chinese range hood, the other is a direct suction range hood, and the third is a side suction range hood. [0004] Chinese range hoods are mainly divided into old-fashioned shallow and deep suction range hoods, which generally refer to ordinary exhaust fans to directly exhaust the range hoods. With the improvement of technology, this type...

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
