The invention belongs to the field of electric appliances, and relates to a glass demisting control device and a glass display cabinet. The glass demisting control device is used for controlling the heating power of electric heating glass in a glass display cabinet. The glass demisting control device comprises a pressure regulator. The input end of the voltage regulator is used for being connected with a power source, the output end of the voltage regulator is electrically connected with the electric heating glass, the voltage regulator is provided with an adjusting component arranged on a shell of the glass display cabinet, and the heating power of the electric heating glass is adjusted through the adjusting component. According to the glass defogging control device, the heating power of the glass of the glass display cabinet can be adjusted through the adjusting component of the glass defogging control device, so that the temperature of the glass of the glass display cabinet can be always above the dew point temperature in various environments, and a better anti-condensation effect is achieved.
Description
technical field [0001] The application belongs to the field of electrical appliances, and relates to a glass defogging control device and a glass display cabinet. Background technique [0002] At present, the glass display cabinet mainly prevents condensation on the glass by means of electric heating and defogging, so that the temperature of the glass is always higher than the dew point temperature so that water vapor does not condense. The common methods of electric heating defogging are divided into laminated glass electric heating wire heating defogging and low-e coated silver paste conductive heating defogging. [0003] The heating and defogging of the laminated glass electric heating wire is mainly by selecting an alloy heating wire with a suitable resistance, and realizing the resistance change through the change of the density of the heating wire, and then matching the transformer according to the resistance of the whole glass, so that the heating of the glass can rea...
