Abstract

PURPOSE:To activate efficiently the human body receiving a magnetic field generated around a heater while users are heated by superimposing a sound signal preferred by the users upon DC current supplied to the heater of a electric bedding body with a music reproducing device to generate the magnetic field around the heater according to the sound signal. CONSTITUTION:A microcomputer 7 compares the temperature of an electric bedding body 6 detected by a temperature sensor 9 with the set temperature to energaize and deenergize a relay coil 8 for removing the temperature difference and adjust a DC power amount supplied to a heater 5 for controlling the temperature of the electric bedding body to the set temperature. On the other hand, when a cassette tape having music recorded thereon is set to a music regenerating device 10, music recorded on a magnetic tape is converted to an electric signal and amplified by a main amplifier to be sent to a transformer 16 for superimposition. The transformer 16 for superimposition superimposes a sound signal on DC voltage supplied to the heater 5 to generate a magnetic field corresponding to the sound signal around the heater 5.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a controller of an electric heating device applied to an electric futon, and FIG. 2 is an external view thereof. A full-wave rectifier circuit 2 is connected to the AC power supply terminals a and b via a main switch 1, and a smoothing capacitor 3 is connected between output terminals of the full-wave rectifier circuit 2. The full-wave rectifier circuit 2 is composed of diodes.

Between the terminals of the smoothing capacitor 3, a capacitor 4 and a heater 5 are provided via a temperature control contact s.
Are connected. The heater 5 is wired to the electric futon body 6 as shown in FIG.

A microcomputer 7 is connected between the terminals of the smoothing capacitor 3, and a relay coil 8 is connected to the microcomputer 7.
And a temperature sensor 9 are connected. Of these, the relay coil 8 closes the temperature control contact s by urging,
The temperature control contact s is opened by releasing the bias. The temperature sensor 9 is wired along the heater 5 wired on the electric futon body 6.

The microcomputer 7 includes a temperature sensor 9
The temperature of the electric futon body 6 is compared with the set temperature, and the relay coil 8 is energized and deenergized so that the temperature difference is eliminated to control the temperature of the electric futon body 6 to the set temperature. It has a function. A music reproducing device 10 is connected between the terminals of the smoothing capacitor 3. This music reproducing device 10 has a function of generating a desired audio signal and superimposing it on DC power as shown in FIG. 3, and its specific configuration is shown in FIG.

The cassette tape 12 is set on the rotating shaft of the motor 11. On the magnetic tape of the cassette tape 12, music or the like desired by the user is recorded. A reproducing head 13 is set on the magnetic tape with the cassette tape 12 set, and a preamplifier 14 and a main amplifier 15 are connected to an output terminal of the reproducing head 13. The superimposing transformer 16 is connected to the output terminal of the main amplifier 15. This superimposing transformer 16
Is connected between the temperature control contact s and the heater 5.

By the way, it is generally said that 700 gauss is effective when a magnetic field is applied to the human body. Therefore, the current value supplied to the heater 5 is adjusted by the main amplifier 15 so that the peak of the magnetic level generated around the heater 5 becomes 700 gauss. Next, the operation of the apparatus configured as described above will be described.

When the main switch 1 is closed, AC power from the commercial AC power source is supplied to the full-wave rectifier circuit 2 through the main switch 1 to be full-wave rectified, and further smoothed by the smoothing capacitor 3. The smoothed DC power is supplied to the heater 5 through the temperature control contact s and also to the microcomputer 7 and the music reproducing device 10.

In this state, the temperature sensor 9 detects the temperature of the electric futon body 6 and sends a temperature detection signal to the microcomputer 7. This microcomputer 7
The temperature of the electric-futon body 6 detected by the temperature sensor 9 is compared with the set temperature, and the relay coil 8 is energized / released so that the temperature difference is eliminated. As a result, the temperature control contact s opens and closes, the amount of DC power supplied to the heater 5 is adjusted, and the temperature of the electric futon body 6 is controlled to the set temperature.

On the other hand, when the cassette tape 12 on which the music of the user's taste is recorded is set in the music reproducing device 10,
The motor 12 is driven, and the music recorded on the magnetic tape is converted into an electric signal by the reproduction bed 13. This electric signal is converted into an audio signal by the preamplifier 14,
Further, it is amplified by the main amplifier 15 and sent to the superimposing transformer 16.

The superimposing transformer 16 superimposes an audio signal on the DC voltage supplied to the heater 5, as shown in FIG. As a result, a magnetic field of 700 gauss at peak is generated around the heater 5 according to the sound signal, and this is applied to the user. In this case, the music recorded on the cassette tape 12 has a comfortable frequency unique to the user,
This frequency is converted into a magnetic field and applied to the user.

Therefore, when this magnetic field is applied to the acupuncture points of the human body, the flow of vital energy is stimulated, and along with this, the nerves are stimulated and transmitted to brain cells. As a result, the cells of the human body are activated and the musical rhythm stabilizes mentally for the user. As a result, the user is healthy both physically and mentally.

As described above, in the above-described embodiment, the user-desired voice signal is superimposed on the DC power supplied to the heater 5 of the electric futon body 6 to generate a magnetic field corresponding to the voice signal. Therefore, in addition to heating the user, a magnetic field is generated around the heater 5 according to the music of the user's taste, and this is added to the user, thereby stimulating the acupuncture points and nerves of the user and efficiently. It can well activate the human body. The present invention is not limited to the above-mentioned embodiment, and may be modified within the scope of the invention. For example, in the above-described one embodiment, the case where the invention is applied to the electric futon has been described, but it may be applied to the electric carpet, the electric blanket and the like. Also, as the music reproducing device 10,
Any device that generates a CD (compact disc) or an audio signal can be applied.
