A temperature controller of electric heating pot

Abstract

The invention relates to a temperature controller of electric heater. Wherein, said controller comprises integrated control unit, heating tube powder switcher, button / switch detector, sound alarm unit; the integrated control unit via I / O is connected to left three units to detect and control them. The invention can realize intelligent, safe, and reliable function with low cost.

Description

Technical field: [0001] The invention relates to the technical field of temperature controllers, in particular to a temperature controller applied to electric heating pots such as electric kettles, coffee pots, teapots, and other related products. Background technique: [0002] With the development of society, electric heating pots (electric kettles, coffee pots, teapots, and other related products) have been widely used in all aspects of social production and life, and various mechanical heating pots have also appeared on electric heating pots. However, the existing thermostat has the following disadvantages: first, once the steam bounce protection switch fails, the electric kettle will not be able to cut off the power supply in time, which will easily lead to dry heating and waste a lot of water and electricity resources; After boiling, there is only an automatic power-off function, and there is no sound alarm function. If the user fails to find out in time and pour out th...

[0002] With the development of society, electric heating pots (electric kettles, coffee pots, teapots, and other related products) have been widely used in all aspects of social production and life, and various mechanical heating pots have also appeared on electric heating pots. However, the existing thermostat has the following disadvantages: first, once the steam bounce protection switch fails, the electric kettle will not be able to cut off the power supply in time, which will easily lead to dry heating and waste a lot of water and electricity resources; After boiling, there is only an automatic power-off function, and there is no sound alarm function. If the user fails to find out in time and pour out the boiling water, the water temperature will drop quickly. When the user needs high-temperature boiling water and finds that the water is cold, he needs to boil the water again , leading to a waste of a large amount of water and electricity resources; third, among the existing thermostats, some thermostats are repeatedly energized when they are in dry-burning protection, but only control the temperature within a certain range, resulting in a large amount of waste of electric energy; fourth, Due to the characteristics of the mechanical structure, when it is necessary to expand and develop related functions, the cost and technical difficulty will rise rapidly
