Abstract
Heater for sleeping such as the electrical blanket that the present invention relates to, both made and before sleep, carried out high temperature preheating, if detect the temperature of user when going to bed by the temperature check device, thereby the energising of control heater wire also can make it automatically restore to the temperature that setting device is set.
Description
The present invention relates to heater for sleeping such as electrical blanket.
In recent years, use electrical blanket to increase gradually as the situation of heater for sleeping.
It is believed that the method for general correct use electrical blanket is that during energising, at first the knob with temperature setting device is set on " by force " scale, switches in advance about one hour, drops to the scale of wishing use when going to bed again.
The problem that exists is, owing to must carry out such operation when using electrical blanket, thus if forget under the state that " by force " scale is set when pre-energising and adjust knob and fall asleep, then will be waken up by heat night, or the like.
The a of Fig. 1, b represent the formation of prior art example, Fig. 1 only switches in advance by knob-operated, the 1st, the electrical blanket main body, the 2nd, be distributed in the heater wire in the above-mentioned electrical blanket main body 1, the 3rd, to above-mentioned heater wire 2 switch on control control device and the built-in controller of power circuit, the 4th, be contained in the thermoregulation knob in the above-mentioned controller 3.
Temperature characterisitic when Fig. 2 represents the electrical blanket use, a point in the drawings is set in knob on " by force " scale, through arriving the b point after about one hour energising, knob is set on the desirable scale when going to bed again.
The objective of the invention is to,, provide a kind of and can make the automatically reset warmer of knob, promptly use safety to be convenient to operation again by temperature check for eliminating the problems of the prior art.
In order to reach this purpose, the present invention is provided with the temperature check device that detects body temperature, according to the output of this temperature check device, can automatically restore to the temperature that setting device is set from the high temperature that sets.
According to this formation, can obtain a kind ofly need not repeating knob-operated, the safe in utilization and warmer being convenient to operate every day.
Below, according to Fig. 3～Fig. 5 one embodiment of the present of invention are described.
Fig. 3 is in the present invention as the formation of the electrical blanket of an embodiment of heater for sleeping.
The represented object of each symbol is identical with Fig. 1 among the figure, therefore explanation no longer separately.The 5th, the temperature check device.
Fig. 4 is the temperature characterisitic of one embodiment of the invention, after the pre-energising of its expression high temperature, by the automatically reset temperature conditions of temperature check.
Fig. 5 is the control block diagram of this embodiment, the 6th, voltage comparator, earlier to the voltage of input temperature check device 5 and the voltage that is used to set on the resistance 7 of reference voltage compare, send the open and close signal then, to control.The 8th, with the temperature adjustment variable resistance of thermoregulation knob 4 interlocks.The 9th, the transistor that variable resistance 8 short circuits are used utilizes the output of above-mentioned voltage comparator 6 to control its conducting, end.The 10th, power circuit.
On constituting, above-mentioned electrical blanket main body 1 disposes single-line type heater wire 2, and it has the function of heating and detected temperatures concurrently, and the temperature check device 5 of human body temperature is contained in main body 1 partly a side on the shoulders that is not subject to heater wire 2 heat affectings.
In the above-described configuration, when connecting power supply, be used for transistor 9 conductings of short circuit in the control block diagram shown in Figure 5, automatically be set at " by force " scale, temperature rises.At this moment, the thermoregulation knob 4 of controller 3 should place on the position of feeling comfortable in bed.Like this, when connecting power supply,, automatically begin pre-energising setting under the state of equivalence with " by force " scale.Then, detect body temperature when going to bed by temperature check device 5, compare with this and voltage on the resistance 7 that is used to set reference voltage, the transistor 9 that variable resistance 8 short circuits are used ends, and automatically restores to the preferred temperature that above-mentioned thermoregulation knob 4 is set.
The effect of utilizing this formation to obtain is, can not forget preheating, removes when carrying out preheating repeatedly that " by force " scale is set from, trouble such as expectation scale setting after the preheating, and not have to cause the danger of low temperature scald owing to forget the cut-out preheating.
The foregoing description is with regard to the explanation of the formation of electrical blanket, adopts formations such as electricity shop blanket or mattress, also can obtain same effect.In addition, also heater wire and the detection line with regard to embodiment is that integrally-built single-line type is described, and adopts it to plant the TW two wire that constitutes and also can obtain same effect, so be not only limited to the scope of the foregoing description.
As mentioned above, utilize heater for sleeping of the present invention, can obtain following effect.
That is to say, during the heater for sleeping such as use electrical blanket, the general energising in advance in " by force " scale earlier, but when going to bed, detect body temperature by body temperature detector, can automatically restore to the temperature that temperature setting device sets from the high temperature of setting, therefore can not forget the preheating setting, and can avoid after the preheating also can under preheat mode, not falling asleep again with troubles such as setting device reset, do not feel well etc. owing to overheated.
The a of Fig. 1, b are the pie graph of existing electrical blanket and the oblique view of major part; Fig. 2 is the temperature characterisitic schematic diagram, and it is illustrated in the prior art example, by manually carrying out preheating, drops to desirable scale after one hour; Fig. 3 is the pie graph as the electrical blanket of the embodiment of the invention; Fig. 4 is the temperature characterisitic schematic diagram of same embodiment; Fig. 5 is the control circuit block diagram of same embodiment.
