Abstract
The utility model relates to a kind of electrothermal blanket, and it comprises electric blanket, switch, infrared inductor and time block; Switch is connected on the power line of electric blanket, and infrared inductor is positioned at electric blanket, and time block is positioned at electric blanket inside; Switch is divided into a plurality of gears, is respectively heating gear, is incubated gear and closes gear, the corresponding corresponding contact of each gear contact, the output of switch in succession voltage regulation resistance and diode; The input of infrared inductor is connecting the output of voltage regulation resistance and diode; Time block is connecting the input circuit of resistance wire.The utility model can detect the situation that has or not personnel to exist on electric blanket by infrared controlled switch, and according to the circuit of the information controlling resistance silk detecting, and set certain hour by time block, within this time, control resistance wire heating, thereby make people by time block, to electric blanket, carry out preheating before sleep, avoid opening for a long time and forget to close power supply phenomenon.
Description
Technical field
The utility model relates to a kind of daily living article, specifically a kind of electrothermal blanket.
Background technology
Electric blanket, has another name called electrical blanket, is a kind of contact electric heating appliance, and it is special, and the soft cable-styled heating that insulating properties reach standard is dish snake shape and inweaves or sew up in woollen blanket, evolution of heat during energising.Be mainly used in improving when people sleep the object that temperature in quilt reaches heating.The tide that goes that also can be used for bed clothes dehumidifies.Its power consumption is few, temperature is adjustable, easy to use, use is extensive, the history of existing more than 100 year.
While using electric blanket, often forget to close power supply, electric blanket is generated heat for a long time, cause the generation of some fire, thereby cause the loss of property and personnel's injures and deaths.
Utility model content
For the above, the purpose of this utility model is to provide a kind of electrothermal blanket, and it utilizes the existence that has or not personnel on the infrared inductor Induction Heating blanket in electric blanket, thereby controls conducting and the disconnection of heater circuit, effectively addresses the above problem.
In order to realize the technical scheme that the purpose of this utility model adopts, be:
An electrothermal blanket, it comprises electric blanket, switch, infrared inductor and time block; Switch is connected on the power line of electric blanket, and infrared inductor is positioned at electric blanket, and time block is positioned at electric blanket inside.
Further, switch is divided into a plurality of gears, is respectively heating gear, is incubated gear and closes gear, each gear corresponding corresponding contact contact, the output of switch in succession voltage regulation resistance and diode.
Further, the input of infrared inductor is connecting the output of voltage regulation resistance and diode, by switch, stable voltage is input to infrared controlled switch, detects the existence that electric blanket has or not personnel, thus conducting and the disconnection of controlling resistance silk circuit.
Further, time block is connecting the input circuit of resistance wire, by time block setting-up time, the power supply that is communicated with resistance wire in setting-up time, makes resistance wire heating, arrives after setting-up time, time block disconnects, thereby makes resistance wire power-off stop heating.
The beneficial effects of the utility model: can detect the situation that has or not personnel to exist on electric blanket by infrared controlled switch, and according to conducting and the disconnection of the information controlling resistance silk circuit detecting, and set certain hour by time block, within this time, control resistance wire heating, thereby make people by time block, to electric blanket, carry out preheating before sleep, avoid opening for a long time and forget to close power supply phenomenon.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model circuit diagram.
In figure, 1-switch, 2-electric blanket, 3-infrared controlled switch, 4-time block.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1, Fig. 2 schematically show the structure of the electrothermal blanket of a kind of embodiment of the utility model.
As shown in Figure 1 and Figure 2, a kind of electrothermal blanket, it comprises electric blanket, switch, infrared inductor and time block; Switch is connected on the power line of electric blanket, and infrared inductor is positioned at electric blanket, and time block is positioned at electric blanket inside.
As shown in Figure 1 and Figure 2, switch is divided into a plurality of gears, is respectively heating gear, is incubated gear and closes gear, each gear corresponding corresponding contact contact, the output of switch in succession voltage regulation resistance and diode.
As shown in Figure 1 and Figure 2, the input of infrared inductor is connecting the output of voltage regulation resistance and diode, by switch, stable voltage is input to infrared controlled switch, detects the existence that electric blanket has or not personnel, thus conducting and the disconnection of controlling resistance silk circuit; While having people on electric blanket, infrared controlled switch detects signal, and control circuit conducting makes resistance wire obtain electric heating; On electric blanket nobody time, infrared controlled switch detects signal, and circuit is disconnected, resistance wire does not generate heat.
As shown in Figure 1 and Figure 2, time block is connecting the input circuit of resistance wire, by time block setting-up time, the power supply that is communicated with resistance wire in setting-up time, makes resistance wire heating, arrives after setting-up time, time block disconnects, thereby makes resistance wire power-off stop heating.
As shown in Figure 1 and Figure 2, infrared controlled switch and time block can be located at electric blanket other can detect and operating position.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make at least one distortion and improvement, these all belong to protection domain of the present utility model.
