Abstract

The invention discloses a liquid crystal display device for a range hood. A sealant is arranged at multiple parts, and consists of the following components in parts by weight: 1-2 parts of bauxite, 0.8 part of bis(P,P-bis-ethylhexyl diphosphato) ethanediolato titanate, 1-2 parts of chitin, 1.4 parts of white carbon black, 1-2 parts of bisphenol F diglycidyl ether, 0.7 part of 2,2,4-trimethyl-1,2-dihydroquinoline, 1-2 parts of kerosene, 2-3 parts of iso-tridecanol polyoxyethylene ether and 18 parts of CTBN modified epoxy resin. The liquid crystal display device for the range hood has unique display design, structure design and protective design; the sealant is also arranged at multiple parts so as to guarantee that the liquid crystal display circuit board is not affected with damp and corrosion for a long time, so that the liquid crystal display control circuit board can be operated effectively for a long time; the sealant can resist high temperature of 116 DEG C and low temperature below -19 DEG C.

Description

technical field [0001] The invention relates to a liquid crystal display device for a range hood. Background technique [0002] At present, the range hood is often equipped with a liquid crystal display device, and the liquid crystal display in the liquid crystal display device needs a liquid crystal display control circuit board to drive and control it. The circuit board is damp and corroded, and the liquid crystal display control circuit board will affect the normal display of the liquid crystal display after being damp and corroded. Contents of the invention [0003] The purpose of the present invention is to provide a liquid crystal display device for range hoods, which has unique display design, structural design and protection design; its aluminum alloy panel and aluminum alloy outer shell are firmly connected, and they will not be separated from each other after long-term use. , the double protection of the inner shell, and the waterproof, moisture-proof, oil-smoke...
