となるなどの欠点があった。(B) Conventional technology Traditionally, there have been portable pocket burners such as coal ash pocket burners, gasoline pocket burners, iron powder disposable pocket burners, and liquefied gas pocket burners. Even if it becomes unnecessary during the heating process, the only option is to leave it in the heating process until the end of the heating process, and of course it is impossible to ignite and extinguish it in small steps. However, there were drawbacks such as the fact that the temperature of the heat generated was difficult to stabilize because it was affected by the accuracy of the gas control valve and the outside temperature. In addition, battery-powered heating vests that use ordinary resistance heating elements are also known, but these use only Joule heat, which consumes a lot of power and consumes a lot of battery power. They had shortcomings, such as a large battery, which would increase the volume and weight, making it unsuitable for wear.

。Figure 4 (10) is a temperature detection circuit, in which the resistance change due to temperature of the thermistor (9) is input through the connected cord (8), and is converted into a change in DC voltage corresponding to the temperature change.

(equivalent to 3), so if a semiconductor is used for control, the supply voltage will drop by around 0.6V, and the power consumption inside the semiconductor will lead to a reduction in drive time, so control by relay was prioritized. It is something.

件にもよるが20%を下回る。At the same time, the secondary battery (B) positive side → the positive side of the cord (8) → Peltier element (PI) → thermoswitch (7) →
A closed circuit is formed with the negative side of the cord (8) → the negative side of the secondary battery (B), and the Peltier element (PUL) is activated and the heat generating plate (3) is heated by Joule heat and the temperature rises.At the same time, the heat absorbing plate ( 4) starts absorbing heat from the outside air and the heat transfers to the heat generating surface (1), so the heat absorbed is added to the heat generating plate (3) which is being heated by Joule heat, and heating progresses further. After several minutes have passed, when the temperature of the heating plate (3), which has risen due to heating, reaches around 65°C, the thermoswitch (1) opens and cuts off the power supply to the Peltier element (PI), so the element (PU) The heating operation is stopped and the temperature of the heating plate (3) gradually decreases, and when it reaches around 58℃ due to the hysteresis of the thermoswitch (7), the switch (7) is closed and power is supplied, and the Peltier element (Putl) is turned on again. starts to operate, the heating plate (3) is heated and its temperature rises, and this operation is repeated thereafter. Therefore, the heating plate (3) always maintains a temperature between 58℃ and 65℃ to warm the body parts. In addition, when the Peltier element (pH) is in operation, the heat absorption plate (4) always absorbs heat and its temperature decreases, so the heat absorption plate (4) can be used as a substitute for an ice pack, such as head cooling. However, in this case, the refrigeration efficiency relative to the power consumption is less than 20%, although it depends on the outside temperature and other conditions.

在することを付記する。In addition, since the hand warmer of this example is used in a bag made of flocked cloth, the actual sensible temperature is around 57'C on average, so there is no risk of low-temperature burns even if the same part is heated for a long time. However, if you feel that the temperature is too high, open and close the power switch (31) to adjust the temperature. In this way, use it for a total of 5 to 6 hours until the secondary battery (8) has discharged. When finished, open the power switch (S), pull up the plug (Pl) that is folded and stored in a part of the battery case (dashed line A), and connect it to a commercial power source. A charging circuit consisting of bridge diodes (BDI)
The secondary battery (B) connected thereto can be charged with an appropriate direct current. According to the latest information, Sony
(corporate name) has announced a AA-type lithium-ion storage battery (product name), which has an energy capacity and energy density 2.9 times that of a nickel-cadmium secondary battery.
It should be noted that there is a secondary battery that has 1,200 charge/discharge cycles and an average operating voltage of 3.6 V, which is optimal as a power supply battery for the hand warmer of this embodiment.

81例と同様である。First, set an arbitrary reference voltage to control the upper limit temperature to 65°C or less using a variable resistor (Vlll) and input it to the reference voltage input terminal (Vrel) of the comparator (12). When the power switch (Sl is closed, Power is supplied to the Peltier element (pu) through the connected break contact (y) and thermoswitch (7), and the heating plate (3)
is heated and its temperature increases, the thermistor (9)
The resistance change corresponding to the temperature is input to the temperature detection circuit (10), converted to a DC voltage corresponding to the temperature, and output to the connected DC amplifier (11), which amplifies this voltage. The voltage is input to the comparison voltage input terminal (V cp) of the comparator (12) connected to the voltage. If this comparison voltage is lower than the set reference voltage, the comparator (
12) is not activated, and the temperature of the heating plate (3) is increased by supplying power to the Peltier element (PU) through the break contact of the relay or the semiconductor in the ON state, and when the comparison voltage exceeds the reference voltage, The comparator (12) operates and the break contact of the relay opens, or the semiconductor turns OFF, cutting off the power supply to the Peltier element, so the heating plate (
3) When the temperature gradually decreases below the set temperature, the comparator (12) will stop operating, so the relay will also stop operating and the break contact will close, or the semiconductor will recover and the O
In the N state, power is supplied to the Peltier element (PU), and the element (PI) operates to heat the heat generating plate (3) again. Thereafter, by repeating this operation, the heating plate (3) can warm the body parts while always maintaining the temperature between about 12 degrees Celsius and the set temperature. The other effects are the same as in the 81st case described above.

第1項記載のペルチェ素子を用いた携帯用懐炉。2. A thermistor is provided in a part of the heating plate to obtain a DC voltage, that is, a comparison voltage, in response to temperature changes of the heating plate, and when the comparison voltage is lower than a reference temperature, that is, reference voltage, arbitrarily set in advance with a variable resistor. for,
The comparator does not operate, but the temperature of the heating plate is increased by supplying power to the Peltier element through the break contact of the relay or the semiconductor in the ON state, and when the comparison voltage exceeds the set reference voltage, the comparator operates. Then, the break contact of the relay opens or the semiconductor turns OFF, cutting off the power supply to the Peltier element and reducing the temperature of the heat generating plate to below the set temperature. A portable hand warmer using the Peltier element according to claim 1, which can be set and used.
