Connecting structure for preventing oil dripping and leakage of oil and smoke exhauster

Abstract

The invention provides a connecting structure for preventing oil dripping and leakage of an oil and smoke exhauster, which comprises a smoke-collecting hood, an oil net, a machine box and an oil-guiding surrounding frame, wherein the oil-guiding surrounding frame comprises a first hem and a second hem, the first hem is closely bonded with the outer side at the lower part of the machine box, the second hem is closely bonded with the upper side at the periphery of the oil net, and the oil net is installed on the oil-guiding surrounding frame. The connecting structure has a simple and reasonablestructure, and the conception of blocking clearance airflows is mainly adopted, thereby the seamless matching among the smoke-collecting hood, the oil net and the machine box of the oil and smoke exhauster is realized; after oil and smoke are pumped into a space between the oil net and the machine box by a fan of the oil and smoke exhauster, the oil and the smoke can not outwards overflow from aninstalling gap between the oil net and the machine box, thereby the problem of oil leakage, oil flow or oil dripping of the oil and smoke exhauster is prevented; and moreover, the oil-guiding surrounding frame is simple to manufacture and convenient to assemble and unassembled, so that the oil net and the machine box can be directly connected, thereby the installing mode of the oil net is greatlysimplified.

Description

technical field [0001] The invention relates to the technical field of household range hoods, in particular to an anti-dripping oil leakage connection structure of the range hood. Background technique [0002] Existing European-style range hoods usually include components such as a fume collecting hood, oil net, and chassis. Based on the direction in which the range hood is used, the oil net is fixed below the chassis. The oil net is usually low in the middle and high around the edges. The duct communicates with the center of the upper part of the fume collecting hood. When the range hood is in use, the case is filled with oil fume. After condensation, the oil fume flows down along the inner wall of the case and finally enters the oil cup through the oil leakage hole. However, due to the inherent characteristics of assembly and metal parts, the range hoods currently manufactured cannot accurately control the fit gap between the fume collection hood, oil screen and chassis, a...

Problems solved by technology

This patent designs a fixed structure of the oil net to prevent oil dripping from the range hood. However, this fixed structure needs to make structural improvements to the edges of the oil net and the smoke collection hood, which increases the technical difficulty of its production. Especially for large-sized components such as oil screens and fume collection hoods, it is technically difficult to make high-precision hemming at the edges, and it is very complicated to install the oil screen, especially on the side protrusions and sockets. Due to structural and precision problems, there are still oil leakage defects at the joint, and the sealing effect is not ideal, so further improvement is needed
