Truly, definitely safe electric blanket resisting high heat and out of control

Abstract

The invention relates to a truly, definitely safe electric blanket resisting high heat and out of control. According to the technical solution, a cushion temperature sensing diaphragm (7) between extra-membrane electric wire (5) and an intra-membrane electric wire (6) that are parallel and are used as temperature sensing lines is used as a temperature sensing device, a temperature detection and break detection circuit (8) is connected between the two electric wires in series, a temperature detection voltage output by the temperature detection and break detection circuit (8) is connected with and controls an over heat and flashfire resisting protective control circuit (9) and a zero-type temperature control circuit (10), then a protective control switch in the over heat and flashfire resisting protective control circuit (9) performs high heat protection control, and the zero-type temperature control circuit (10) regulates normal temperature of the electric wire. The truly, definitely safe electric blanket resisting high heat and out of control can regulate normal temperature without interference and has a high heat protection control function as well as a protection control functionpreventing electric wire from breaking and flashing fire, and ensures that an AC power supply is cut off reliably and effectively and is under control, thereby guaranteeing truly, definitely safe.

Description

technical field [0001] The invention belongs to the field of household appliances or electric heating control, and in particular relates to an electric heating device that is absolutely true and safe in the whole process of use, whether it is in a normal state or in an abnormal fault state, which can completely prevent flash fire, prevent high heat protection failure, and prevent out of control. Blanket, abbreviated as: a certain electric blanket that prevents high heat out of control. Since the electric blanket is a flexible electric heating body, the present invention is also particularly suitable as a Bian controller for other electric heating bodies. Background technique [0002] The electric blanket is the preferred heating appliance for warming the bed when it is cold. It not only makes people feel warm and comfortable when sleeping and improves the quality of sleep, but also its radiated infrared rays and low-frequency electromagnetic fields have some physical therapy...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to design an electric heating temperature controllable and overheating protection, electric heating wire (wire) break arc protection function, and no matter in normal or abnormal state, the overheating protection function of the whole line must be effective, and the whole process can prevent out of control. Ensure that the electric blanket controller must be real and safe; solve the technical problems of the existing electric blankets in the past when the high temperature is out of control and cause fire accidents when abnormal faults occur, and completely eliminate the safety hazards and defects of the existing electric blankets in the past
