Anti-dry glass electric kettle

Abstract

The invention relates to an anti-dry glass electric kettle, which includes a glass kettle body and a far-infrared electric heating film, and the far-infrared electric heating film is installed on the outer surface of the bottom surface of the glass kettle body. The controller is mounted on the outer surface of the bottom surface of the glass jug body and electrically connected in series with the far-infrared electric heating film, and the temperature controller is a bimetallic sheet temperature controller. When there is no water in the glass pot body and the far-infrared electric heating film continues to work, the temperature at the bottom of the glass pot body rises sharply. When the temperature reaches a certain value, the thermostat disconnects and cuts off the working circuit of the far-infrared electric heating film. Burning function, the thermostat is a bimetal thermostat, which belongs to mechanical control. It has a simple and compact structure, reliable operation, and easy installation. It effectively protects the glass kettle and improves the safety level.

Description

Technical field: [0001] The invention relates to a dry-boiling-proof glass electric kettle. Background technique: [0002] Existing electric kettles generally use a metal (stainless steel) pot body, and a heating plate is installed at the bottom of the pot body. The heating plate includes an electric heating tube and a heat conduction plate poured on the outside of the electric heating tube. This heating method mainly uses heat conduction. , low efficiency, relatively heavy, and the metal (stainless steel) pot body is easy to deposit scale, and it is inconvenient to clean. It cannot break up the water molecular clusters and cannot improve the structure of the water molecular clusters. Therefore, it is not conducive to human body absorption, and the pot body is opaque. The condition of the water cannot be observed and there is a risk of heavy metal precipitation. [0003] In view of this, the inventor has developed an electric kettle with a glass body. A far-infrared electri...

AI Technical Summary

Problems solved by technology

[0005] 1) The heating element of the stainless steel electric kettle is the heating plate (the electric heating tube is cast on the aluminum plate). It is difficult to achieve consistency, the power of different batches is different, even in the same batch, the power is difficult to ensure consistency, which makes the circuit control not as simple as the stainless steel electric kettle, and must be redesigned to be suitable for far-infrared electric heating film heating. The independent circuit and each functional circuit module of the glass electric kettle;

[0006] 2) The glass electric kettle is highly sensitive to temperature. Due to the high power provided by the control circuit, the temperature difference of the glass kettle will inevitably be too large, which will lead to cracking, resulting in product scrapping, and more serious safety accidents, such as burns\fires etc. Such hidden dangers affect the popularization and application of glass electric kettles

[0007] 3) The glass electric kettle has no anti-dry function. Once the glass kettle has no water and continues to heat dry, the heating heat cannot be taken away by the water, which will cause the local temperature at the bottom of the glass kettle to rise sharply, which will also cause the glass kettle to crack, resulting in product failure. scrapped, more seriously, safety accidents, such as burns\fires
