The electric blanket comprises a controller, a thermo-sensitive resistor, a fuse temperature sensor, an insulated gate bipolar transistor (IGBT) and an electric pressure converter, wherein the output end of a power supply is connected with the power terminal of the controller, one end of the IGBT and one end of a fuse; the other end of the fuse is connected with one end of the thermo-sensitive resistor; the other end of the IGBT is connected with the thermo-sensitive resistor; the driving end of the IGBT is connected with the signal output end of the controller; the sensor is fixed on the thermo-sensitive resistor; and the output end of the sensor is connected with the input end of the controller. The temperature-control electric blanket disclosed by the utility model has the advantages of low electric consumption, adjustable temperature, convenience for use and wide application.
Description
Technical field
The utility model belongs to technical field of electric appliances, and particularly a kind of temperature is controlled electric mattress.
Background technology
Being commonly called as of electric blanket, the electric heating appliance that utilizes resistance heating element to generate heat.Formed by resistant to elevated temperatures insulator and the wire of braid parcel or the outer wrapping layer of banded heating, control circuit, safety apparatus and fabric tissue etc.The not types such as temperature control type, stepping temperature control type and continuous adjustable temperature control type are arranged.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of temperature to control electric mattress.
The technical solution of the utility model is achieved in that this temperature control electric mattress comprises controller, thermistor, insurance temperature sensor, IGBT and electric pressure converter, wherein an end of the end of the power supply terminal of the output terminal of power supply and controller, IGBT and fuse is connected, the other end of fuse is connected an end and is connected with thermistor, the other end of IGBT is connected with thermistor, the drive end of IGBT is connected with the signal output part of controller, being fixed on thermistor of sensor, the output terminal of sensor is connected with the input end of controller.During device work, controller sends the driving signal, the IGBT conducting, and main circuit is started working, and when temperature reached setting value, temperature sensor was to the controller transmitted signal, and controller turn-offs and drives signal output, and main circuit quits work.
Advantage of the present utility model: power consumption is few, temperature can be regulated, easy to use, use is extensive.
Description of drawings
Fig. 1 is that temperature is controlled the electric mattress structural drawing.
Embodiment
