Heating control system of electric blanket

Abstract

A heating control system of an electric blanket comprises a control unit and a heating part. The control unit is used for controlling the heating part. The heating part comprises a first heating unit and a second heating unit. When receiving a third signal from a switch unit, the control unit starts a timing unit to start timing and starts one of the first heating unit and the second heating unit. When keeping time to the preset time, the timing unit sends a switch signal to the control unit, is reset and restarts timing. When receiving the switch signal from the timing unit, the control unit enables the first heating unit or the second heating unit which is opened to be closed, and enables the first heating unit or the second heating unit which is closed to be opened, and accordingly opening and closing of the first heating unit and the second heating unit are switched.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, the invention relates to an electric blanket heating control system. Background technique [0002] Electric blanket, also known as electric mattress, is a contact electric heating appliance. The electric blanket wove or sews special cable-type electric heating elements with insulation properties up to the standard into the blanket in the shape of a snake, and it emits heat when it is energized. [0003] Electric blankets are mainly used to increase the temperature in the bed when people sleep to achieve the purpose of heating. The electric blanket can also be used for dehumidification and dehumidification of bedding. Electric blankets have a history of more than 100 years because of their low power consumption, adjustable temperature, convenient use, and wide use. [0004] Electric blankets have many advantages. For example, electric blankets have a good protective ef...

AI Technical Summary

Problems solved by technology

[0005] However, since the user generally uses the electric blanket for a long time when using the electric blanket, the heating unit of the electric blanket will continue to work for a long time (for example, continue to work for more than ten hours)

However, if the heating unit continues to operate for a long time, the service life of the heating unit will be shortened, and the probability of burning out the heating unit and causing a fire will increase
