Temperature control module for glass electric kettle

Abstract

The invention relates to a temperature control module for a glass electric kettle. The electric kettle includes a glass kettle body, a far-infrared electrothermal film, a plurality of temperature detection circuits, a main control chip and a second driving circuit, wherein the far-infrared electrothermal film is mounted on the outer surface of the bottom of the glass kettle; after being connected in series with a temperature control switch, the far-infrared electrothermal film is connected with an external power supply to form a main working circuit; a plurality of area temperature signals of the bottom of the glass kettle body are transmitted to the main control chip through the temperature detection circuits; when the difference between the area temperature signals exceeds a certain value, the main control chip sends a control signal to the second driving circuit, and the second driving circuit disconnects the temperature control switch, so as to cut off the power supply to the far-infrared electrothermal film. The temperature control module for the glass electric kettle achieves overall monitoring of the temperature of the bottom of the glass electric kettle; when the local temperature is too high, the power supply to the far-infrared electrothermal film is temporarily cut off, so as to effectively protect the glass electric kettle, eliminate potential safety hazards, and improve the product reliability and stability.

Description

Technical field: [0001] The invention relates to a temperature control module of a 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-in...

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 and fires.
