Multi-layer efficient heating module used for deposition of electrical appliance low-melt-grease plastic casing

Abstract

The invention provides a multi-layer efficient heating module used for deposition of an electrical appliance low-melt-grease plastic casing. The multi-layer efficient heating module comprises a first hot melting layer, a first energy storage layer, a first heat conduction layer, a second heat conduction layer, a second energy storage layer and a second hot melting layer which are overlaid in sequence, and a heating disc is arranged between the first heat conduction layer and the second heat conduction layer in an embedded mode. By means of the multi-layer efficient heating module used for deposition of the electrical appliance low-melt-grease plastic casing, the qualified rate is increased, meanwhile by means of the multi-layer structure design, heat energy of the heating module is distributed more uniformly, heat among all the layers is effectively transmitted and stored, so that the heat utilization efficiency is improved, and accordingly the purpose of energy saving is achieved.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a multi-layer high-efficiency heating module for welding low-melting fat plastic shells of home appliances. Background technique [0002] At present, the traditional home appliance shell cladding is mainly based on electric heating or ultrasonic, and the traditional heating module used is mainly aluminum alloy, which has poor surface finish and wear resistance, and the molten plastic shell is easy to stick to the heating plate. The product is poorly sealed, and the heating module is used for heating the whole area, with high power and serious energy waste. Contents of the invention [0003] The invention provides a multi-layer high-efficiency heating module capable of improving product sealing, which is used in an electric heating welding device to melt a plastic shell and can improve heat utilization efficiency. [0004] In order to solve the problems of the tec...
