Abstract
The utility model discloses an electric blanket with the function of automatic temperature control, which is put forward for overcoming the defects that a plurality of temperature steps of the existing electric blanket are only operated by manual regulation so that the existing electric blanket has the defects of complicated operation and no automatic operation of power on and off for temperature control. The utility model is characterized in that the circuit of the electric blanket comprises an electric heating wire which is arranged in the electric blanket body and connected with an electrical plug, and furthermore, a thermostat which is provided with an IC temperature-sensing element and can realize the automatic control of the temperature is connected with the circuit which is connected by the electrical plug and the electric heating wire. When the utility model is used, people can preset a temperature, the temperature value inside the electric blanket can be transmitted to the thermostat for temperature regulation through the IC temperature-sensing element, so that the temperature of the electric blanket can vary within the range from minus 0.5 DEG to plus 0.5 DEG, once exceeding or lowering, the power is switched off automatically. People can feel comfortable without manual regulation when sleeping on the utility model, and the utility model has the advantages of temperature control, electricity saving, simple circuit structure and low cost, and changes the defect of the prior art which can only vary among two or three temperature steps.
Description
Technical field
The utility model belongs to daily necessities, specifically a kind of electric blanket of the usefulness of warming oneself.
Background technology
The electric blanket of Chu Shouing in the market is by the electric blanket body, be installed in the heating wire that is connected with plug in the electric blanket and the manual temperature regulating switch that is connected on the circuit is formed.Because affiliated manual temperature regulating switch has only two to three temperature adjustment retainings, several temperature adjustment retainings are with regard to several temperature of furnishing, and need turn thermoregulation knob with hand when changing temperature and regulate, trouble not only, and can not realize that automatic power on-off controls temperature a suitable scope.
The utility model content
Technical problem to be solved in the utility model is, overcoming prior art can only be with manual adjustments several temperature retaining trouble, can not realize that automatic power on-off controls the shortcoming of temperature an OK range, and a kind of temperature self-controlled electric blanket is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the circuit of electric blanket comprises the heating wire that is installed in the electric blanket body, is connected with plug, on plug and circuit that heating wire is connected, be connected with band IC temperature-sensing element, can realize temperature automatically controlled self-operated thermostatic controller.
Advantage of the present utility model and good effect are, owing to be connected with self-operated thermostatic controller in the circuit of electric blanket, the consumer can preestablish a temperature, by the IC temperature-sensing element temperature value in the electric blanket body is passed to the self-operated thermostatic controller temperature adjustment, the temperature of electric blanket can be changed in positive and negative 0.5 ℃ scope, surpass or reduction back realization outage automatically, the people is slept just feel comfortable without the hand adjustment joint in the above, and can also control temperature, economize on electricity, changed prior art and only blocked the deficiency of variation two to three temperature, circuit simple in structure, low cost of manufacture.
Description of drawings
Fig. 1 is a schematic circuit of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, A, B two-end-point at bridge rectifier are connected with the contact that can be inserted in the plug on the power supply respectively, the electromotion pilot lamp DI and the resistance R 3 that are parallel with capacitor C and are connected together at its E, F two ends; The positive pole of controllable silicon VD1 is connected with the F end, and negative pole connects self-operated thermostatic controller RT by resistance R 1, the R2 of series connection, and self-operated thermostatic controller RT is made up of adjustable resistance R5 and temperature-sensitive original paper IC; The base stage of triode V connects self-operated thermostatic controller RT control signal output ends, and its emitter is connected with the trigger end of controllable silicon VD1, and its collector electrode is connected between resistance R 1, the R2; The other end of self-operated thermostatic controller RT is connected with the E end.The positive and negative polarities of voltage stabilizing didoe VD2 are connected to the two ends of self-operated thermostatic controller RT; The end of heating wire RL is connected between controllable silicon VD1 and the resistance R 1, and the other end is connected in the E end, and the relay indicating light D2 and the resistance R 4 of series connection are in parallel with heating wire RL.
When the electric blanket circuit with after power supply is connected, by the temperature-sensing element IC temperature-sensitive on the control circuit, with its signal by triode V to the temperature adjustment electric current amplify, controllable silicon VD1 is in the break-make of its range of set temperature inner control heating wire RL, can finish the automatic adjusting to electric blanket temperature.
