Description

The thermostatic electric heating blanket of predeterminable temperature

Technical field

The utility model relates to the electric blanket class, is a kind of thermostatic electric heating blanket of predeterminable temperature specifically.

Background technology

People pass the winter and depend on very much electric blanket now.But the electric blanket on the present market has only simple high low temperature to regulate mostly, does not have the constant temperature function, therefore is easy to grow in the time at night, is not that people's heat is waken up, and is exactly cold awake the people.In addition, everyone hobby of sleeping is different, and what have likes focus, and disliking of having is too hot, so we are sought after designing for market and a kind ofly can preset the hobby temperature, can keep the electric blanket of constant temperature again.

Summary of the invention

The purpose of this utility model provides a kind of thermostatic electric heating blanket of predeterminable temperature.

The thermostatic electric heating blanket of described predeterminable temperature comprises an electric blanket, it is characterized in that: the power lead of this electric blanket is provided with a control enclosure, and temperature sensor is installed on the electric blanket; Described control enclosure panel is provided with power switch, temperature display, rise key and down key, is provided with single-chip microcomputer, temperature controller in the control enclosure; Wherein temperature sensor, rise key, down key link to each other with the input interface of single-chip microcomputer, and temperature display, temperature controller link to each other with the output interface of single-chip microcomputer, and the heating wire in the blanket links to each other with the output interface of temperature controller.

This device need cooperate by the built-in program of single-chip microcomputer finishes function corresponding.

The utility model is practical, and the temperature of predeterminable hobby, and can keep constant temperature allows comfortable that the people sleeps, and is the good assistant that people sleep winter.

Description of drawings

Fig. 1 is the utility model structural representation,

Fig. 2 is the utility model electrical principle block diagram.

Among the figure: the 1-control enclosure, the 2-temperature sensor, the 3-power switch, the 4-temperature display, 5-raises key, 6-down key, 7-single-chip microcomputer, 8-temperature controller, 9-heating wire.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified: the thermostatic electric heating blanket of predeterminable temperature as shown in Fig. 1,2, comprise an electric blanket, the power lead of this electric blanket is provided with a control enclosure 1, and temperature sensor 2 is installed on the electric blanket; Described control enclosure 1 panel is provided with power switch 3, temperature display 4, raises key 5 and down key 6, is provided with single-chip microcomputer 7, temperature controller 8 in the control enclosure 1; Wherein temperature sensor 2, rise key 5, down key 6 link to each other with the input interface of single-chip microcomputer 7, and temperature display 4, temperature controller 8 link to each other with the output interface of single-chip microcomputer 7, and the heating wire 9 in the blanket links to each other with the output interface of temperature controller 8.

Described single-chip microcomputer 7 can use ARM, DSP or other intelligent processor to replace, also can plug-in D/A, and modules such as sound circuit.Described temperature controller 8 can be electronic switch or relay, also can be that conduction angle is subjected to monolithic processor controlled controllable silicon.Temperature sensor can be one or more, is located at the diverse location of electric blanket, and temperature signal is returned to single-chip microcomputer.

Electrical principle block diagram below in conjunction with Fig. 2 carries out the principle explanation.

After electric blanket completed, line plugged in.Press power switch 3, start working after system powers on.

After single-chip microcomputer 7 initialization, to initial temperature value of temperature display 4 outputs, the user regulates and raises key 5 and down key 6 according to the sleep temperature of oneself liking, the push button signalling of two keys passes to single-chip microcomputer 7 simultaneously, single-chip microcomputer 7 simultaneously with adjusted temperature value echo to temperature display 4.

After configuring temperature, single-chip microcomputer 7 control temperature controllers 8, temperature controller 8 heats heating wire 9 again.

Meanwhile, temperature sensor 2 constantly detects the temperature of electric blanket, and numerical value is passed to single-chip microcomputer 7, and single-chip microcomputer 7 compares with the temperature value of setting.When if the temperature of comparative result electric blanket does not reach setting value, control temperature controller 8 continues to give heating wire 9 heating; When comparative result was higher than setting value, single-chip microcomputer 7 control temperature controllers 8 reduced electric current or stop to heating wire 9 heating.Control so repeatedly, reach the effect of constant temperature.

Claims
