Abstract
The utility model discloses an electric heating carpet which comprises an electric heating carpet body and a controller, wherein the controller is provided with a control switch used for controlling the on-off of a power supply of the electric heating carpet; the electric heating carpet body is internally provided with a plurality of resistance wires and a temperature control device; the resistance wires are connected with a variable resistor in series, and the variable resistor is electrically connected with a temperature set switch; and the temperature control device is respectively and electrically connected with constant temperature switches of the resistance wires and the controller. According to the electric heating carpet, the electric heating carpet body is directly placed at a part of the body so as to meet the warming requirement of people and is simple and practical.
Description
Technical field
The utility model relates to a kind of electric blanket, especially relates to a kind of electric heat mat.
Background technology
Along with economic development, people's living standard is in continuous improve, people to the requirement of using electric heating products occupation mode and comfort winter also in continuous change.Because people see TV in the parlor in winter, the study of perhaps bending over one's desk working, or little poly-the playing card when game etc. situation of friend, even general family is not because the reasons such as the electricity charge are used air-conditioning yet in winter, so people can feel that generally shank, foot or buttocks are colder, even because cold affects or shortens our work and study and quality and the time of entertainment life.
The utility model content
Technical problem to be solved in the utility model is: a kind of electric heat mat is provided, directly the electric heat mat body is positioned over the health desired area, thereby satisfy people's heating needs, and simple and practical.
For solving the problems of the technologies described above, the technical solution of the utility model is: electric heat mat, comprise electric heat mat body and controller, described controller is provided with the gauge tap that control electric blanket power supply opens and closes, be provided with some resistance wires and attemperating unit in the described electric heat mat body, described resistance wire electricity is in series with variable resistor, and described variable resistor is electrically connected with described temperature setting switch, and described attemperating unit is electrically connected with the thermostat of described resistance wire and controller respectively.
Preferably, described attemperating unit comprises the thermistor that is arranged in the described electric blanket blanket body and the control circuit of connecting with described thermistor, and described thermistor is arranged at the periphery of described resistance wire.
Preferably, also be provided with between described controller and the resistance wire be used to prevent that electric blanket is overheated, short circuit and the current insurance silk that opens circuit.
Adopted technique scheme, the beneficial effects of the utility model are: owing to designed above-mentioned electric heat mat, because this electric heat mat body can directly be positioned over the position of each required heating of health, thereby satisfy people's heating needs, and simple and practical.Owing to also be provided with attemperating unit in the electric blanket blanket body, attemperating unit is electrically connected with the thermostat of resistance wire and controller respectively, attemperating unit comprises the thermistor that is arranged in the electric blanket blanket body and the control circuit of connecting with thermistor, thermistor is arranged at the periphery of resistance wire, utilize thermistor in different temperature ranges, can produce different resistance value principles, detect constantly the electric blanket temperature, comparison circuit by operational amplifier, the resistance value of thermistor changed analyze and judge, when the temperature that detects the electric blanket body surpasses preset value, cut off circuit by IGCT, stopped heating when the temperature that detects the electric blanket body is lower than preset value, is connected circuit by IGCT, continue heating, thereby reach the purpose of constant temperature.
Since also be provided with between controller and the resistance wire be used to prevent that electric blanket is overheated, short circuit and the current insurance silk that opens circuit, play the effect of safeguard protection.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Wherein: 1, electric heat mat body; 2, controller; 3, resistance wire; 4, variable resistor; 5, temperature setting switch; 6, thermostat; 7, thermistor; 8, gauge tap; 9, current insurance silk; 10, operational amplifier.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1; electric heat mat; comprise electric heat mat body 1 and controller 2; controller 2 is provided with the gauge tap 8 that control electric heat mat power supply opens and closes; be provided with some resistance wires 3 and attemperating unit in the electric heat mat body 1; resistance wire 3 electricity are in series with variable resistor 4; variable resistor 4 is electrically connected with temperature setting switch 5; attemperating unit is electrically connected with the thermostat 6 of resistance wire 3 and controller 2 respectively; attemperating unit comprises that the control circuit that is arranged at the thermistor 7 in the electric blanket blanket body 1 and connects with thermistor 7 is (because this control circuit is not well known to those of ordinary skill in the art; do not repeat them here); thermistor 7 is arranged at the periphery of resistance wire 3; also be provided with between controller 2 and the resistance wire 3 be used to preventing that electric blanket is overheated; short circuit and the current insurance silk 9 that opens circuit play the effect of safeguard protection.
This electric heat mat utilizes thermistor 7 can produce different resistance value principles in different temperature ranges, detect constantly electric heat mat body 1 temperature, comparison circuit by operational amplifier 10, the resistance value of thermistor 7 changed analyze and judge, when the temperature that detects electric heat mat body 1 surpasses preset value, cut off circuit by IGCT, stopped heating, when the temperature that detects electric heat mat body 1 is lower than preset value, connect circuit by IGCT, continue heating, thereby reach the purpose of constant temperature.
This electric heat mat body 1 can directly be positioned over shank, foot or the buttocks of health, not only has common electric blanket use function in bed, the demand of all right dealing with various requirements whole body or local heating, expanded the use field, simple and practical, dependable performance, working service is convenient.This electric heat mat body 1 can directly use on the ground, also can be placed on the chair and use, people can be sitting on the electric heat mat, also can be placed on pin on the electric heat mat, the heat of electric heat mat body 1 just all is gathered in lower part of the body position, directly allows people feel comfortably cool, thereby brings more efficient, more comfortable work and study entertainment life for people, this electric heat mat is particularly suitable for the women and uses, and especially the cold women of body uses better.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
