Abstract

The invention provides an intermittent temperature controller for an electric blanket. The intermittent temperature controller for the electric blanket comprises a 220V alternating-current power source, a resistance-capacitance voltage-reducing rectification circuit, a 12V voltage stabilizing circuit, an intermittent oscillation circuit, an intermittent time adjustment circuit, an electric blanket driving circuit and an electric blanket working condition indicating circuit, and is characterized in that the model of a binary serial counting integrated circuit IC1 is HEF4060. A traditional electric blanket temperature control switch is too simple, an electric blanket continuous energized mode is changed into an intermittent energized mode by the aid of delay heat inertia of the electric blanket temperature, the intermittent oscillation circuit outputs high level intermittently to trigger on of a bidirectional thyristor, and accordingly continuous energized operation of the electric blanket is changed into intermittent energized operation, the requirement that a heating wire of the electric blanket is adjusted to heat intermittently and further to control the temperature is met, the defects of the existing electric blanket temperature control switch are overcome, and electric power consumption is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic technology and temperature control, and relates to an intermittent temperature controller for an electric blanket. Background technique [0002] Its temperature control of various electric blankets that are popular now has only two gears almost without exception, namely: high temperature gear, low temperature gear, and the temperature of electric blanket can't regulate temperature when working in high temperature gear or low temperature gear. When the temperature control switch is set to high temperature, the electric blanket will sometimes wake up due to the high temperature after falling asleep; when the temperature control switch is set to low temperature, the elderly will feel that the temperature of the electric blanket is not enough in the middle of the night. In actual use, users of different ages have different requirements for the working temperature of electric blankets, and the two-s...
