Abstract

The invention discloses a liquid crystal display device capable of displaying a timing clock for a range hood. Sealants are arranged on multiple parts and comprise the following components in parts by weight: 0.8 part of antiager TPPD, 12 parts of xylene formaldehyde resin, 0.9 part of coal ash, 0.4 part of superfine talcum powder, 0.6 part of fumed silica, 1-2 parts of 1,2-dihydro-2,2,4-trimethylquinoline homopolymer, 5-6 parts of dimer acid modified epoxide resin, 2-3 parts of isocyanate, and 1-2 parts of sodium polyacrylate. The liquid crystal display device capable of displaying the timing clock for the range hood has unique display design, structure design and protection design; the sealants are arranged on the multiple parts, thereby ensuring that a liquid crystal display control circuit board is not affected with damp and corroded and can work effectively for a long term. The sealants can resist a high temperature of 109 DEG C, and a low temperature of -22 DEG C.

Description

technical field [0001] The invention relates to a liquid crystal display device for range hoods capable of displaying timing clocks. 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 object of the present invention is to provide a liquid crystal display device for range hoods capable of displaying timing clocks, which has unique display design, structural design and protection design; its aluminum alloy panel and aluminum alloy outer shell are firmly connected, and will not interact with each other after long-term use It has the double protection ...
