A vacuum shock absorption plate for a range hood and a range hood bellows using the same

Abstract

The invention relates to a vacuum shock-absorbing plate for absorbing range-hood smoke, and a range hood bellows employing the same, and the vacuum shock-absorbing plate and the range hood bellows are used in a kitchen range hood. The vacuum shock-absorbing plate of the range hood is characterized by comprising an interior plate, a support member and an exterior plate; the shock-absorbing plate with an interval space is formed by mutual encapsulating of the interior plate and the exterior plate; the interval space between the interior plate and the exterior plate forms a sealed vacuum chamber; and support members are disposed between the interior plate and the exterior plate for supporting. The vacuum shock-absorbing plate can be used as a sound-insulating shock-absorbing plate; the vacuum shock-absorbing plate helps to effectively reduce vibration and noise of the bellows when applied to the range hood bellows; and also the vacuum shock-absorbing plate has the advantages of simple structure, good sound insulation and shock absorption effects, long service life and the like.

Description

technical field [0001] The invention relates to a vacuum damping plate of a range hood and a bellows of the range hood using the plate, which are applied to kitchen range hoods. Background technique [0002] Range hoods are also known as range hoods, range hoods, range hoods, range hoods, etc. Although there are many types of range hoods on the market, these range hoods are only different in appearance and installation, and the structure and working principle of the range hood itself have not changed. It consists of a hollow chassis, an exhaust pipe, and one or more electric fans. In order to enhance the smoke exhaust performance of range hoods, most range hoods also use high-power, high-efficiency impellers. Although the intensity of air extraction is increased, the rotation of the impellers generates vibrations and produces relatively loud noises. [0003] The existing patent technology discloses a plastic-encapsulated vacuum sheet and its application (application number...

AI Technical Summary

Problems solved by technology

In order to make the smoke extraction performance of the range hood stronger, most range hoods also use high-power, high-efficiency impellers. Although the strength of the air extraction is increased, the rotation of the impeller generates vibration and produces a lot of noise.

[0003] The existing patent technology discloses a plastic-encapsulated vacuum sheet and its application (application number: 201010279689.8; publication number 101936443A), which is characterized in that at least two sheets are sealed with an air-tight plastic film, and a small The gaps separated by the supports vacuumize the packaging space to make a plastic-encapsulated vacuum sheet. The "tiny support" in the above patent is used as a support, which has a small force surface, limited support force output, and no shock absorption. function, the manufacturing process is complex

[0004] The existing patent technology also discloses a heat-preserving and silent vacuum panel (application number: 200910163568.4; publication number: 101994350A). The presence of the vacuum plate area and the pressure increase the folded support body. The "folded support body" in the above patent is used as a support, and its force-bearing surface is small, and the support is mainly supported by the elastic force of the folds. When the elastic force is due to When it is weakened by long-term force, it will affect its supporting effect, and the vacuum plate is easy to deform, which will affect the service life of the product
