Abstract

The invention discloses an energy-saving electric blanket temperature controller. The energy-saving electric blanket temperature controller comprises a 220 V alternating current power supply, a resistance capacitance voltage reduction rectification circuit, a 12 V direct current voltage stabilization circuit, an intermittent oscillation circuit, an intermittent time adjustment circuit, an electric blanket drive circuit and an indication circuit, and is characterized in that the type of a binary serial counting integrated circuit IC1 in the intermittent oscillation circuit adopts HEF4060 or CD4060. The continuous power-on mode of the electric blanket is changed into the intermittent power-on mode through the phenomenon that the temperature of the electric blanket has delay thermal inertia, so that the length of the power-on time of the electric blanket is changed. The continuous power-on mode of the electric blanket is changed into the intermittent power-on mode in a way that the intermittent oscillation circuit intermittently outputs high level to trigger the conduction of bidirectional controllable silicon, so that the purpose of adjusting the electric heating wires of the electric blanket to intermittently generate heat for temperature control is achieved. According to the energy-saving electric blanket temperature controller, the use effect of the electric blanket cannot be affected and the power consumption is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic temperature control, and relates to an energy-saving electric blanket temperature controller. Background technique [0002] The temperature control of various electric blankets on the market has only two gears almost without exception, namely: high temperature gear and low temperature gear. When in use, if the temperature control switch is set to a high temperature setting, the elderly will feel that the temperature is not enough in the middle of the night when the temperature control switch is set to a low temperature setting. In actual use, users of different ages have different requirements for the working temperature of electric blankets, and the traditional electric blanket temperature control switch is too extensive. [0003] In order to overcome the defects of the existing electric blanket temperature control switch in the market, it is necessary to study a controller that can steplessl...
