Description

Technical Field

[0001] The utility model relates to the technical field of door panel reinforcement, and more specifically to a door panel reinforcement structure for a large door. Background Art

[0002] In the field of electrostatic fume removal industry, improving the sealing performance of door panels can directly reduce the energy consumption of the exhaust fan at the rear end of the equipment. The door panel structure on the market now is basically a single-layer door panel structure. A soft plastic sealing strip is clamped (or attached) on the door panel, one end of the door panel is fixed by a door hinge, and the other end is tightened and fixed to the cabinet with a door handle. The door panel design of the electrostatic fume removal equipment on the market must take into account the sealing and rigidity of the door panel, so it is generally difficult to make a very large door panel. When the door panel is too large, not only is the rigidity of the door panel insufficient, but it is also prone to drooping and deformation over time, resulting in poor sealing.

[0003] The existing patent is a large cabinet type detachable door panel structure, the patent authorization number is CN 206190163 U. It solves the problems of poor sealing of single-layer door panel structure, insufficient rigidity of door panel and easy sagging and deformation, and difficult cleaning and maintenance. It adopts a double-layer door panel structure design to enhance the sealing of door panels, facilitate the disassembly and cleaning of inner door panels, reduce oil leakage, and has the advantages of relatively light weight, good rigidity, good sealing, and can be disassembled and cleaned.

[0004] However, when the size of the door panel is large, the rigidity and strength of the door panel are greatly reduced, causing the entire door panel to shake easily during use. In order to improve the overall structural strength of the large-opening door panel, we propose a large-opening door panel reinforcement structure to solve the above-mentioned problems.
