The cover has wider versatility, convenient and fast disassembly and assembly of the decorative cover, simple and reliable installation, can realize the automatic lifting adjustment of the decorative cover, and can realize the seamless connection between the decorative cover and the suspended ceiling.

Description

Technical field [0001] The present invention relates to a hood purification apparatus, in particular a decorative hood mounting device, and an oil absorbing hood using the mounting device. Background technique [0002] The decorative cover of the suction hood is used to block the outblow cover and the outlet tube on top of the smoke hood, play a beautiful, decorative role, the decorative cover is usually drawn from the top of the suction hood, and the height according to the high and low of the user's house adjust. The decorative cover is typically divided into a lower decorative cover fixed to the box and can perform the upper and lower pandem, which is usually provided inside the lower decorative cover due to aesthetics and safety. The lower decoration cover is divided into two different forms: 1, the split type decorative cover can be installed after the smoke hood is installed, and it is fixed to the casing, usually the exposed screw, has aesthetics, integrity, installation T...

AI Technical Summary

Problems solved by technology

The lower decorative cover is divided into two different forms: 1. The split lower decorative cover, which can be fixed on the box after the range hood is installed, usually with exposed screws, which is aesthetically pleasing, integral and easy to install. The firmness is poor, but the installation is easy. When installing this kind of decorative cover, you need to install the upper decorative cover first, so that the upper decorative cover extends into the left / right support frame from front to back, and then install the lower decorative cover. The lower part of the cover and the box are wrapped together; 2. The integrated lower decorative cover, that is, it is integrally connected or integrally formed with the range hood box, which not only has decorative functions but also usually has functional functions. For example, there are Switches or lamps, etc.; this type of integrated lower decorative cover is usually used for high-end range hoods, and its characteristic is that the lower decorative cover cannot be installed afterward, and is connected with the whole machine in one piece, so the upper decorative cover can only be pulled from bottom to top

[0003] The existing drawable decorative cover has the following problems: 1. The gap between the decorative cover and the suspended ceiling is too large, which affects the appearance

2. Before installing the decorative cover, you need to remove the range hood shell first, which is inconvenient to install

3. Connect the decorative cover to the hook or the wall from the outer surface of the decorative cover by screwing, which destroys the appearance of the whole machine

4. When it is necessary to clean the smoke pipe covered by the decorative cover or repair the electrical parts covered by the decorative cover, it is necessary to remove the shell of the range hood, which is inconvenient to disassemble

In the actual product application process of this installation structure, the following problems are found: 1. The installation accuracy of the hook is high: in the vertical direction, the distance between the hook and the ceiling needs to be measured by the installer and carried out according to the design requirements. Fixed, if the hook is installed too high, the decorative cover cannot be installed, if it is too low, there will be a gap between the decorative cover and the ceiling, which will affect the appearance

2. Easy to fall off: Since the structure is connected with the surface of the lock tongue and the hook, if the hook is installed to the left or right, it will directly affect the size of the contact surface between the lock tongue and the hook bracket

In addition, the motor of the range hood has self-excited vibration during high-speed operation, and the impeller of the range hood is affected by the manufacturing process and the user's working conditions, and there is a certain dynamic balance deviation. There is a small vibration

Long-term vibration accumulation makes the lock tongue and hook shift to the left or right or forward until the two are disengaged, causing the decorative cover to fall off

3. The front end of the lock tongue is exposed, which affects the appearance

That is to say, this installation structure is only suitable for the decorative cover of the above-mentioned form 1, but cannot be used for the decorative cover of the form 2; and it is only suitable for the decorative cover of one size model, if the decorative cover is widened or narrowed, If it cannot be installed, it needs to be adjusted again according to the specific size of the decorative cover; although the extension spring can be used for automatic installation during the installation process, when the decorative cover needs to be disassembled, the extension spring becomes the source of resistance for disassembly, resulting in difficulty in disassembly
