Description

Technical Field

[0001] The utility model relates to an installation structure of a filter screen support plate for a columnar range hood.

Background Art

[0002] A range hood is installed in a kitchen to suck the cooking fumes generated during cooking and discharge the fumes outdoors to keep the air quality in the kitchen. At present, there are various types of range hoods on the market. The columnar range hood is one of them, which is suitable for top suction and hanging use. However, for the columnar range hoods on the market at present, the filter screen is installed on the bottom plate, and the bottom plate is usually fixed by using multiple screws. Although screw fixation has the advantages of easy installation and disassembly, when using multiple screws for fixation, the installation of the screws and the alignment of the screw holes will affect the overall production efficiency of the columnar range hood.

[0003] Therefore, it is necessary to make further improvements to it.

Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above problems. We provide an installation structure of a filter screen support plate for a columnar range hood. By adopting this structure, the filter screen support plate can be quickly disassembled and assembled.

[0005] To achieve the above purpose, the utility model provides an installation structure of a filter screen support plate for a columnar range hood, which includes a columnar housing and a filter screen support plate. A hanging plate is provided on the inner wall of the columnar housing at the bottom opening, and a bayonet is opened on the hanging plate. A hook is provided at the position of the filter screen support plate corresponding to the bayonet, and the hook can pass through the bayonet and be hung on the hanging plate.

[0006] In one or more embodiments, the hanging plate and the columnar housing are of an integral structure, and the bottom edge of the columnar housing is bent inward to form the hanging plate.

[0007] In one or more embodiments, the hanging plate is fixed to the columnar housing by bonding or welding.

[0008] In one or more embodiments, the filter screen support plate is connected and fixed to the columnar housing by screws, and holes are opened on both the filter screen support plate and the columnar housing for screw connection.

[0009] In one or more embodiments, an air inlet is opened on the filter screen support plate, and a range hood filter screen is clamped on the air inlet.

[0010] In one or more embodiments, a lighting lamp is further provided on the filter screen support plate, and the lighting lamp is arranged on the front side or left and right sides or rear side of the range hood filter screen.

[0011] The effects of the present utility model compared with the background technology are as follows: When installing the filter screen support plate, just align the hook with the bayonet, then push the filter screen support plate to make the bayonet enter the bayonet, and then translate the filter screen support plate, and the filter screen support plate can be fixed on the cylindrical shell without using screws for fixation, which greatly improves the production efficiency.

Specific Embodiments

[0014] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0015] Refer to the attached Figure 1-2 , this application provides a filter screen support plate installation structure for a cylindrical range hood, which includes a cylindrical shell 1 and a filter screen support plate 2. A hanging plate 3 is provided on the inner wall of the cylindrical shell at the bottom opening. Specifically, the hanging plate and the cylindrical shell are an integral structure, and the hanging plate is formed by bending the bottom of the cylindrical shell inward; alternatively, the hanging plate is fixed on the inner wall of the cylindrical shell by welding or bonding, and it is specifically selected according to actual production needs, and no limitation is made here.

[0016] A bayonet 4 is opened on the hanging plate, and a hook 5 is provided on the filter screen support plate 2 corresponding to the position of the bayonet 4. The hook can pass through the bayonet and be hung on the hanging plate. Specifically, after aligning the hook on the filter screen support plate with the bayonet, lift the filter screen support plate to make the hook pass through the bayonet, and then move the filter screen support plate forward to make the hook hang on the hanging plate to complete the installation; when disassembling, move the filter screen support plate backward to make the hook on the filter screen support plate disengage from the hanging plate, and then pull the filter screen support plate downward to make the hook withdraw from the bayonet to disassemble.

[0017] The filter screen support plate 2 is connected and fixed to the cylindrical shell 1 by screws. Holes 6 are opened on both the filter screen support plate and the cylindrical shell for screw connection. Adding a screw to connect the filter screen support plate and the cylindrical shell can prevent the filter screen support plate from shifting during the daily use of the range hood.

[0018] An air inlet is formed on the filter screen support plate 2, and a range hood filter screen 7 is clamped on the air inlet. The range hood filter screen is a common range hood filter screen on the market at present, with elastic latching tongues, which is convenient for installation and disassembly. An illuminating lamp 8 is also arranged on the filter screen support plate 2. The illuminating lamp is arranged on the front side or the left and right sides or the rear side of the range hood filter screen. The specific setting position of the illuminating lamp is selected according to actual needs and is not limited here.

[0019] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed by the present invention shall be included in the protection scope recorded in the claims.
