Glass heating kettle with far infrared heating film

Abstract

A glass heating kettle with a far infrared heating film comprises a glass kettle body and a control base, a heating layer is arranged on the bottom of the glass kettle body, and a control circuit board is arranged in the control base. The glass kettle body is formed and is made of high borosilicate glass, a resistor heating layer is arranged on the bottom of the glass kettle body through the silk-screen technology that electrothermal film pulp is printed on the bottom of the glass kettle body, and two electrode layers are coated on the surface of the heating layer and are used as conductors. The control circuit board comprises a circuit control module, a PWM direct-current output module and a detection control module. According to the glass heating kettle with the far infrared heating film, a PWM direct-current control circuit is adopted, and the power input of a glass heating part is guaranteed to be stable in heating operation. The output power of the circuit control part is output in a slowly rising and stepped manner within a certain time at the beginning, a relay is used as a switching element, and an electric supply is rectified, and then a direct-current power supply isseparated from a load interface completely. The glass heating kettle with the far infrared heating film solves the problem that electricity is leaked caused by the fact that heated liquid is leaked from partial breaks of the glass kettle heating body when the glass kettle is powered directly. The glass heating kettle with the far infrared heating film solves the problem of the potential safety hazards when the existing glass kettles are used.

Description

Technical field: [0001] The invention belongs to the field of heating appliances and is a household heater with a glass body used for boiling water and soup, and in particular relates to a glass heating pot with a far-infrared heating film. Background technique: [0002] The existing glass heating jug comprises a glass jug and a circuit board control part. The heating part of the glass jug is a resistance layer formed on the outer wall of the bottom of the glass body, and the surface of the resistance layer is coated with two electrode layers as electrical conductors. The circuit control part is used to control the conduction current and conduction time control system of the glass heating resistance layer. Since the above-mentioned heating part of the glass is composed of the glass body and the transparent body coating layer, during the heating process, the mains power supply voltage is too large and the direct AC power supply will cause the glass heating body to heat unbal...

AI Technical Summary

Problems solved by technology

Since the above-mentioned heating part of the glass is composed of the glass body and the transparent body coating layer, during the heating process, the mains power supply voltage is too large and the direct AC power supply will cause the glass heating body to heat unbalanced, due to the poor thermal conductivity of the glass, resulting in The local temperature of the glass heating element is too high in an instant, and the shrinkage rate of the pot body is inconsistent, resulting in glass body rupture, resulting in the leakage of the heating liquid, causing hidden dangers of electric leakage, and bringing safety hazards to users
