Multifunctional ceramic dual temperature controller and electric heating container using same

Abstract

The invention relates to the technical field of temperature controllers, and particularly relates to a multifunctional ceramic dual temperature controller, which comprises a ceramic shell. The upper end opening of the ceramic shell is sleeved with an aluminum cover; the upper end opening of the ceramic shell is internally provided with a guiding support; two groups of broken circuit switches are arranged parallelly inside the ceramic shell below the guiding support; two action rods capable of moving vertically are arranged on the guiding support; lower ends of the two action rods are in linkage with the broken circuit switches respectively; two disc bimetallic sheets are fixed between the guiding support and the aluminum cover; and upper ends of the two action rods are in abutting linkage with the corresponding bimetallic sheets respectively. According to the multifunctional ceramic dual temperature controller, the structure is reasonable, a PTC heating body is adopted to maintain power-off protection in the case of abnormal functions, poor contact generated as conductive metal is likely to oxidize can be avoided, serial connection and parallel connection demand configuration and multilevel control protection can be realized through integrated multilevel configuration, problems of poor safety performance, short service life and small application range of the existing temperature controller are overcome, and the application cost of an electric appliance is reduced.

Description

technical field [0001] The invention relates to the technical field of temperature controllers, in particular to a multifunctional ceramic double temperature controller, and at the same time, the multifunctional ceramic double temperature controller is used on an electric heating capacitor. Background technique [0002] The reset type thermostat is a common temperature control overheating protector on household appliances at present. It has the functions of self-acting protection, permanent disconnection without power failure, and self-reset function after power failure. Household appliances are generally equipped with reset-type thermostats with power-off protection to protect household appliances from damage caused by excessive operating temperature or dry burning. With the advancement of technology, the functions of household appliances are becoming more and more complex, and the requirements for functional control and safety mechanisms are also higher. Because the tradit...

Problems solved by technology

With the advancement of technology, the functions of household appliances are becoming more and more complex, and the requirements for functional control and safety mechanisms are also higher. Because the traditional thermostat has a single function, it is often necessary to install multiple thermostats in one appliance. To play automatic control functions such as overheating protection, power-off heat preservation, circuit switching, etc.

[0003] However, to achieve the performance requirements of electrical appliances through multiple thermostats, the setting requirements for the electrical structure and layout are relatively high, and the overall structure is complex and difficult to assemble, resulting in high material costs and processing costs for electrical appliances.

The switching of electrical functions through the adjustable thermostat avoids the problem of complex assembly, but in the process of frequent use, there are problems of mechanical wear and precision inaccuracy, which makes the thermostat unable to realize the effective switching of electrical functions. and Bao

Moreover, most of the working parts of the existing thermostat are in direct contact with the air, the surface of the conductive parts is easily oxidized, the overall insulation performance is poor, the service life is short, and the critical temperature is prone to misalignment when used for a long time, and its safety is difficult to obtain.
