Description

[Detailed description of the invention] This invention provides a tfil that can be used both as an electric blanket and an electric bed sheet.
I? - (Electric potential) Regarding treatment equipment, electric TJv 4
It is characterized by being able to perform electric field treatment while enjoying the heat retention effect such as 1i.

In recent years, more and more people are using electric blankets (hereinafter also referred to as electric blankets) because they are preferred for their appropriate heat retention, but on the other hand, field (potential) therapy devices (devices) are also important for health and health promotion. The number of users with a purpose is rapidly increasing.

By the way, an electric field (potential) therapy device is a device that places the human body in a certain electric field and creates a potential difference between the head and feet to perform treatment, and the favorable therapeutic effects are as follows. This has been proven.

However, in the past, it was thought that such an electric blanket and a 'Pt field therapy device could not be used together.

It is because conventional electric blankets are designed to use 10 AC as power source, so if the electric field therapy device (for example, 5,000 to 5,110 AC high voltage power source as power source)
When used in combination with the electric field therapy device (applying 0 V for 1 hour), the above-mentioned high-voltage potential difference will occur between the human body and the electric blanket, which may pose a danger due to the long insulation of the blanket.・By the In current flowing to the electric blanket side, ν1
This is due to the fact that it is not possible to create the necessary and sufficient potential difference between the base and the foot.

Conventional electric blankets also create some kind of potential difference between the head and feet of the human body by covering them, so it is possible that they could be used as potential therapy devices. In fact, it is a device whose sole purpose is to retain heat, and it is not intended to serve as an electric field therapy.
Naturally, because the alternating current voltage used was low, the effects of electric field therapy could not be maintained.

However, people who undergo electric field therapy find that the treatment time is
There is a strong desire to use an electric blanket for long periods of time and when feeling cold, and the emergence of a device that combines both mental health care and heat retention has been eagerly awaited. .

In this 5, this invention focuses on making it possible to use an electric blanket to maintain its heat retention effect and simultaneously obtain the effect of electric field treatment during the treatment time. It is.

It is appropriate for an electric field treatment chamber to use direct current, alternating current, or a combination of both as its power source, and the present invention is a device that applies such a principle. In other words, as one source for these electric blankets, there are AC, DC, or both fully superimposed power supplies, power supplies whose voltages are variable, and even DC parts of these DC' power supplies and AC/DC superimposed power supplies. By using a power source that has undergone polar conversion, voltage and polarity can be obtained according to the therapeutic effect.

Note that these electric blankets are provided with a necessary insulation function so as to be able to handle the high voltage of the AC voltage.

The configuration of each side shown in the attached drawings will be specifically described below.

FIG. 1 shows an embodiment of an electric blanket (1) of the present invention.

That is, several heating wires (2) covered with a drowsy insulating material are placed inside the electric blanket (1) so as to be parallel to the longitudinal direction along the head and feet, and they are electrically connected. They are connected in parallel and a conductive wire (3) is connected to both ends of the conductive wire (3), and this conductive wire (3) is connected to the power supply device EK.

FIG. 2 shows another embodiment, in which an electric M made of one wire is shown.
The wires (2) are arranged so as to meander in the width direction of the electric blanket (1) and advance in the longitudinal direction.

FIG. 6 is a circuit diagram showing an embodiment of the power supply device tE, in which the commercial power source is transformed to an appropriate voltage by a transformer T1,
This is a device that simultaneously generates heat and an alternating electric field on the surface of the electric blanket (1) by guiding it to the heating wire of the electric blanket (1). (

Connected to electric blanket (1).

FIG. 4 shows an electric ω;1 device E1 of another embodiment f,
A sliding voltage adjustment transformer T2 is added to the circuit shown in FIG. 3, so that the value of the output voltage can be adjusted freely.

FIG. 5 shows a power supply device #E2 of another embodiment, in which a rectifier (S) is inserted on the secondary side of the transformer T to half-wave rectify the output voltage, and a polarity changeover switch SW is used to
It is K-shaped so that its polarity can be changed. Note that a smoothing capacitor may be connected between A and B in the figure.

FIG. 6 shows a power supply device E3 of another embodiment.
By adding a sliding voltage regulator T2 to the circuit shown in the figure, the output voltage can be adjusted freely.

FIG. 7 shows a power supply device E4 of another embodiment, in which the output voltage is full-wave rectified using four rectifiers S1 on the secondary side of the transformer, and the polarity is further changed by a polarity changeover switch SW. It was designed so that Note that a smoothing capacitor may be connected between A and B in the figure.

FIG. 8 shows a power supply device E6 of another embodiment.
A sliding residual voltage A-adjusting transformer T2 is added to the circuit shown in the figure, so that the output voltage can be adjusted freely.

FIG. 9 shows a power supply device E6 of another embodiment, in which L2. Two % of L3 (z#i
There is a rectifier S and a smoothing capacitor ○ connected to the winding L2 (a center tap may be used), and the winding L2
The output of is half/& rectified and superimposed on the output of winding TJ3. Therefore, when an AC power source is connected to the primary coil LI of the transformer T3, a voltage of 11L (where AC and DC are superimposed) appears at the output terminals tI + t2, which generates heat and an AC/DC superimposed electric field in the electric blanket (1). .

Figure 10 shows another example power supply system flfE7, in which a resistor (R) [or capacitor] and a rectifier (s) are connected in parallel on the secondary side of the transformer T1. When an AC power source is connected to the primary side of the transformer TI, an AC/DC superimposed voltage is generated at the output terminal.

It is flexible, and the polarity of the DC voltage can be switched.

Note that the above-mentioned functions of the electric blanket are also used in the electric blanket.

This invention makes it possible to receive the effect of electric field therapy in an appropriate heat-retaining state by making electric blankets, blankets, etc., which were conventionally considered to have only a heat-retaining effect, also have an electric field treatment effect. This allows the patient to receive electric field therapy at the same time while staying comfortably warm, which helps to further enhance the therapeutic effect.
