Description

Range hood decoration cover mounting structure

Technical Field

The invention relates to a range hood, in particular to installation of a decorative cover of the range hood.

Background

The decoration cover of the range hood is used for shielding an air outlet cover and an air pipe at the top of the range hood, plays a role in beauty and decoration, can be usually drawn out from the top of the range hood, and can be adjusted in height according to the height of a house of a user. The traditional range hood decorative cover is supported by the hook fixed by the screw, during installation, the hook of the decorative cover is fixed on a wall by the expansion screw, then the decorative cover is horizontally pushed into the groove of the front cantilever of the hook of the decorative cover, and finally the fan outer cover is installed. During installation, workers generally need to punch four holes on a wall to install expansion screws during operation, so that not only is installation troublesome, but also because the installation space of the decorative cover is narrow and the distance between the hook hole of the decorative cover and the hook hole of the whole machine below the decorative cover is relatively short, the ceramic tile is easy to crack during punching, and construction is inconvenient; in addition, the decorative cover needs to be hooked again when being adjusted up and down, so that the installation cost and the installation time are increased, and even the installation of the decorative cover cannot be completed smoothly due to the narrow installation space of the decorative cover; and the fixed supporting point is arranged on the single side of the decorative cover, and has a larger distance with the center of gravity of the decorative cover, thereby leading the decorative cover to tilt forward and leave the seam.

An improved structure is disclosed in the prior art, and is disclosed in the Chinese patent application with the application number of 201510627658.X, namely 'an inner decoration cover installation structure and a range hood' (the publication number of CN 106556039A). in the application, in the installation process of the decoration cover, the height of the decoration cover is adjusted by fixing holes at different positions on an installation seat and a main case so as to meet the height requirements of different spaces. It can be seen that although the application can realize height adjustment, the height adjustment is limited by the number and precision of the fixing holes, stepless continuous adjustment cannot be realized, the adjustment range is narrow, and in the adjustment process, related parts need to be moved, so that the operation is troublesome.

In order to overcome the problems of complex installation and the like, people propose a decoration cover installation structure of a range hood, which is disclosed in the invention patent of invention patent application No. CN201610594200.3 (publication No. CN106051873A) of the invention patent of decoration cover installation structure of a range hood, and comprises a fan frame and a decoration cover, wherein the decoration cover can move up and down relative to the fan outer cover, the outer side wall of the decoration cover abuts against a limiting plate positioned outside the decoration cover, torsion spring installation supports are arranged on two opposite side walls of the fan frame, a torsion spring and a torsion adjusting piece are installed on the torsion spring installation supports, a first force application end of the torsion spring abuts against the corresponding inner side wall of the decoration cover, and the torsion adjusting piece can directly act on a second force application end of the torsion spring and further can adjust the pressing force of the first force application end of the torsion spring on the inner side wall of the decoration cover.

The structure is mainly fixed by the close fit friction force between the parts, the installation is relatively convenient, the problem of forward tilting and seam separation also exists, and meanwhile, the structure is not rigidly fixed, so that the structure also has the gliding risk
