An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a planar heating device applied to an electric futon. The planar heater 2 is connected to the output terminal of the rectifier circuit 1 composed of a diode bridge via the output contact Sg and the respective polarity changeover switches Sa and Sb interlocking with each other. This planar heater 2 is formed integrally with the electric futon main body, and is made of cotton impregnated with carbon.

A temperature control circuit 3 is connected to an output terminal of the rectifier circuit 1. The temperature control circuit 3 has a function of controlling the amount of DC power supplied from the rectifier circuit 1 to the planar heater 2 based on the temperature difference between the temperature of the planar heater 2 and the set temperature. That is, in the rectifier circuit 1, the voltage dividing resistor Ra and the temperature adjustment variable resistor Rb are connected in series, and the thermistor RS and the voltage dividing resistor Rc are connected in series. These contacts, that is, the contact between the voltage dividing resistor Ra and the temperature adjustment variable resistor Rb, and the contact between the thermistor RS and the voltage dividing resistor Rc are connected to the respective input terminals of the comparator 4.
The output terminal of the comparator 4 is connected to the base of the output transistor Q via a resistor Rd. An output relay coil 5 is connected to the collector of the output transistor Q. Note that the output relay coil 5
The output contact Sg opens and closes when the bias is released.

On the other hand, a polarity switching circuit 6 is provided.
The polarity switching circuit 6 includes the polarity switching switches Sa, Sb
Has the function of switching the polarity of DC power supplied to the planar heater 2 at predetermined intervals. Specifically, a time switching timer 7 is provided.
Is connected to the switching relay coil 8. The switching relay coil 8 opens and closes the polarity changeover switches Sa and Sb by energizing and releasing the energizing. The time switching timer 7 is for energizing / releasing the switching relay coil 8 every predetermined time. Next, the operation of the electric comforter configured as described above will be described.

When the power is turned on, the AC power is rectified by the rectifier circuit 1 and supplied to the temperature control circuit 3, where the voltage dividing resistor Ra, the temperature adjusting variable resistor Rb, and the thermistor RS are connected.
The voltage is divided by the voltage dividing resistor Rc and input to the comparator 4.

The comparator 4 compares the divided voltage values and outputs a high-level or low-level signal according to the magnitude of these divided voltages. In this case, a resistance value according to a desired temperature is set in the temperature adjustment variable resistor Rb,
The resistance value according to the temperature of the planar heater 2 in the thermistor RS is shown.

Therefore, each divided voltage value to the comparator 4 depends on the temperature of the sheet heater 2 and the set temperature. For example, if the temperature of the sheet heater 2 is lower than the set temperature, the comparator 4 becomes high. A level signal is output to turn on the transistor Q. When the transistor Q is turned on, the output relay coil 5 is energized and its output contact Sg is closed. As a result, the DC power is supplied to each polarity switch S
a and Sb are supplied to the sheet heater 2.

The supply of the DC power causes the planar heater 2 to generate heat and raise the temperature of the electric futon body. Then, when the temperature of the planar heater 2 rises and becomes higher than the set temperature, the comparator 4 outputs a low level signal and turns off the transistor Q. Thereby, the output contact S
g is opened, and the supply of DC power to the planar heater 2 is cut off. Thus, the output contact Sg is opened and closed by comparing the temperature of the sheet heater 2 with the set temperature, and the temperature of the sheet heater 2 is controlled to the set temperature.

By the way, since DC power is supplied to the planar heater 2, ionization corresponding to the electric field as shown in FIG. 2 is formed on the surface of the planar heater 2. That is,
An anion “−” appears on the negative electrode side, and a cation “+” appears on the positive electrode side.

Here, when this electric futon is applied to the human body, the pores and sweat lines of the human body are expanded and enlarged by the anion "-", the activity of the internal organs is activated, and the operation of the nervous system is returned to normal. In addition, it exerts actions such as enhancing mental functions, for example, judgment and attention. Moreover, pores and sweat lines on the skin surface are contracted and reduced by the cations.

On the other hand, the time switching timer 7 energizes and de-energizes the switching relay coil 8 at predetermined time intervals, and controls opening and closing of the polarity switching switches Sa and Sb at predetermined time intervals. This opening / closing control switches the polarity of the DC power supplied to the planar heater 2. That is, in FIG. 2, the negative electrode side is switched to the positive electrode, the positive electrode side is switched to the negative electrode, and accordingly, the positions where the anions “−” and the cations “+” appear are also switched.

Accordingly, an anion "-" and a cation "+" are repeatedly added to the human body at predetermined intervals. This means that pores and sweat lines are expanded by anions “−” and contractions of pores and sweat lines on the skin surface by cations are repeated. In other words, it has the same effect on the human body as entering a so-called sauna.

As described above, in the above-described embodiment, DC power is supplied to the sheet heater 2 so that cations “+” and anions “−” appear on the electric futon main body and are supplied to the sheet heater 2. Since the polarity of the DC power is switched at predetermined intervals, not only can it be used as a normal electric futon, but also cations “+” and anions “−” can be displayed on the surface of the sheet heater 2 and applied to the human body or the like. Can be given. In particular, by giving an anion "-" to the human body, the pores and sweat lines of the human body are enlarged and enlarged, the activity of the internal organs is activated, the function of the nervous system is returned to normal, and the function of the psyche, for example, judgment It can exhibit actions such as enhancing power and attention.
Further, by repeatedly applying an anion “−” and a cation “+” to the human body, it is possible to provide the human body with the same effect as when entering a so-called sauna.

The present invention is not limited to the above embodiment, but may be modified within the scope of the invention. For example, in the above-described embodiment, a case where the present invention is applied to an electric futon has been described.
You may apply to an electric blanket etc.

[0020]

As described above in detail, according to the present invention, cations and anions are repeatedly displayed on the sheet heater, and in particular, the pores and sweat lines of the human body are expanded and enlarged by the anions, and the internal organs are enlarged. Activates the nervous system, restores the nervous system to normal, and enhances the mental function.These anions and cations are repeatedly given to the human body to enter the so-called sauna. An effect can be provided to the human body, and a sweat heater of the human body can be contracted and relaxed to provide a planar warming device capable of obtaining an ion electrostatic effect.
