Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an electric carpet with an electric potential treatment device in which thermal treatment and electric potential treatment are added to the heating function.

(Conventional technology) Heat treatment is effective in activating blood circulation, strengthening metabolism, etc. by resonating cells with far infrared rays that reach 40 to 50 mm below the skin of the human body and heating from deep inside. Electric carpets are well-known household appliances that can perform electrical therapy that is highly effective in regulating blood components and improving acidic constitution through ionic effects that provide a certain kind of electrical energy to the human body. As shown in the figure, a heating element 2, for example a planar heating element, which is energized by a control circuit that controls the heating temperature to a set temperature, is arranged in the carpet 1 and is also used as the electric potential therapy conductor 7, and is controlled by the operation of the changeover switch 19. It was a device that switched between electric potential treatment and thermal treatment (heating).

(Problems to be solved by the invention) Since the conventional device described above is a switching system, it is not possible to obtain electric potential treatment and heating at the same time. There were some handling difficulties, such as the need for a separate heating device to use it as a treatment device.

In order to address these problems, the present invention can perform electric potential treatment in parallel with heating operation, and has two functions with a single structure.
It was designed to provide an electric carpet that can exert the same effect as the ionizer, and by using a simple control system to automatically and alternately operate the ion in a divided manner without affecting the heating function. The aim is to achieve effective treatment.

(Means for Solving the Problems) As clarified by the drawings showing the embodiments, the present invention is energized by the ON output of the control circuit 5 that controls the heat generation temperature to the set temperature, and is deenergized by the OFF output. A heating element 2 and a potential therapy conductor 7 to which the potential generated by the potential generator 6 is applied are arranged in the carpet 1, and the potential generated by the potential generator 6 is connected to the off output of the control circuit 5. Correspondingly, a control means 8 is provided to energize the potential treatment conductor 7 and de-energize it in response to an on output, and the potential treatment conductor 7 is formed of metal foil and also serves as a protective electrode 4 for preventing electric shock. At the very least, it constitutes an electric carpet with an electric potential therapy device.

(Function) The present invention is capable of energizing the potential therapy conductor 7 while the heating element 2 is out of operation to produce an ion effect, and automatically performs heating and potential therapy simultaneously in a time-sharing manner. Able to drive.

Since parallel operation is possible through automatic switching in this manner, the protective electrode for preventing electric shock can also be used as the potential treatment conductor 7.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In Fig. 1, reference numeral 1 denotes a carpet, which is constructed by sequentially laminating an insulating sheet made of polyester film, a carbon surface heating element 2, an insulating sheet made of polyester film, and a carpet surface material on a backing material having heat insulating properties. Furthermore, a temperature sensor 3 is installed inside the carpet 1 in a zigzag pattern to detect the temperature of the carbon heating element 2, and an aluminum foil is placed on the front side of the carbon heating element 2 with the insulating sheet in between. It further includes a protective electrode 4 made of metal foil.

A controller that is electrically connected to the heating element 2, temperature sensor 3, and protective electrode 4 for operation control may be provided integrally at one corner of the carpet, or may be installed separately and connected by wiring. This controller, which is attached to the body, includes a control circuit 5, a potential generator 6, a control means 8, a power switch 10, a coupling circuit 9, and a relay 11, as shown in the exploded view.

The control circuit 5 includes a rectifier circuit that rectifies the AC 100V power to a low DC voltage for control when the power switch 10 is turned on, a temperature detection circuit connected to the temperature sensor 3, and a temperature setting circuit that sets the heat generation temperature. When the temperature of the heating element 2 is lower than the set temperature in the temperature setting circuit, an on output is issued, and when it is higher, an off output is issued to operate the control means 8, and control the start/stop of the heater 2 and the potential. Generator 6
It is formed to control the

When an off output is generated, the control circuit 5 operates the control means 8 to deenergize the relay 11 and open the bipolar contact to disconnect the heating element 2 from the AC 100V power supply, and also to It operates by connecting the primary side of the generator 6 to the AC 100V power supply, and when an ON output is generated, the relay 11 is energized to supply the heating element 2 with AC power.
100V is applied and the primary side of the potential generator 6 is disconnected from the AC 100V power supply.

Next, when the AC 100V power supply is applied to the primary side, the potential generator 6 boosts the voltage and rectifies it to DC to generate a potential with respect to the ground at the output terminal, and connects the coupling circuit 9. formed so that a potential can be applied to the protection potential 4 through the
The protective electrode 4 is also used as a potential treatment conductor 7.

To further explain the above structure using Figure 2,
Normally closed contacts (two) of relays, which are elements of the control means 8, are connected in series to the primary side of the potential generator 6, respectively, and the control circuit 5 receives a detection signal from the temperature sensor 3. The temperature detection circuit 12, the temperature setting circuit 13 for setting the temperature of the heating element 2 stepwise or steplessly within the maximum and minimum range, and the outputs of both circuits 12 and 13 are compared to determine "H". ” output or “L” output, the comparison circuit 16 is emitting an “H” output to energize the heating element 2, and if this continues for a certain period of time T ₁ , the comparator circuit 16 outputs the The forced interrupt circuit 14 (see Fig. 4) changes the "H" output that had been in use to the "L" output for a predetermined period of time T ₂ (see Figure 4), and sends a danger signal (from the heating element 2 and When a signal (generated by a decrease in the resistance value between the protective electrodes 4) is transmitted, the electric shock prevention circuit 15 changes the "H" output to "L" output and starts, the comparator circuit 16, the forced interrupt circuit 14, and the electric shock An AND circuit 17 that takes the AND of each "H" output with the prevention circuit 15, a transistor 18 connected in series to the coil of the relay 11 and turned on by the "H" output of the AND circuit 17, and a transistor 18 that connects the coil to the coil of the relay 11. The relays 8 are connected in parallel and constitute an element of the control means 8.

Further, the coupling circuit 9 is provided with a switching contact of a relay which constitutes an element of the control means 8, and the contact on the normally closed side is interposed in the wiring connecting the protective electrode 4 and the potential generator 6. The contact on the open side is interposed in the wiring connecting the protective electrode 4 and the electric shock prevention circuit 15.

It should be noted that the above-mentioned coupling circuit 9 may, of course, be of an electronic type using a diode D shown in FIG. 3 instead of the above-mentioned contact type.

The configuration of each embodiment has been described above, and next, the mode of operation will be explained using the examples shown in FIGS. 1 and 2.

When the power switch 10 is turned on, if the temperature of the heating element 2 is lower than the temperature set by the temperature setting circuit 13, the comparator circuit 16 outputs "H", and both the forced interrupt circuit 14 and the electric shock prevention circuit 15 output "H". By transmitting the "H" output, the transistor 18 is turned on so that the AND circuit 17 transmits the "H" output, and thus the relay 11 and the control means 8 are activated and the heating element 2 is energized. On the other hand,
Since the protective electrode 4 and the electric shock prevention circuit 15 are connected through the coupling circuit 9, the electric carpet enters heating operation, and at the same time the protective electrode 4 acts as a protective electrode for detecting abnormalities such as pin pricks.

On the other hand, although the potential generator 6 is generating a predetermined potential, the connection with the protective electrode 4 which also serves as the potential treatment conductor 7 is cut off by the coupling circuit 9.

When the temperature of the heating element 2 reaches the set temperature, the output of the comparator circuit 16 becomes "L", or when the energization of the heating element 2 reaches a certain time T1, the forced interrupt circuit ₁ is activated.
4 output becomes "L" or electric shock prevention circuit 1
When the AND circuit 17 outputs an "L" output due to the abnormality detection of the output terminal 5, the transistor 18 is turned off, and thus the relay 11 and the control means 8 are deactivated. While the heating element 2 is de-energized, the potential generator 6 and the protective electrode 4 are brought into conduction by switching the coupling circuit 9.

As a result, the protective electrode 4 is energized with a potential by the potential generator 6 and acts as a potential therapy conductor 7, and the electric carpet is automatically switched from heating to potential therapy.

In this way, as soon as the power supply to the heating element 2 is interrupted due to automatic temperature control, forced interruption, or detection of an abnormality such as pinprick, the electric potential treatment is automatically switched to, so that the heating effect is not affected in any way. The electric potential treatment operation is performed in a time-division manner.

(Effect of the invention) As is clear from the above explanation, in the present invention, heating by the heat generated by the heating element 2 and electric potential treatment by energizing the electric potential are operated alternately by automatic switching giving priority to the former. Therefore, electric potential treatment can be performed at the same time without any damage to the heating function.
This is an electric carpet with great practical value.

In that case, in particular, since the electric potential treatment conductor 7 also serves as the protective electrode 4 for preventing electric shock, electric potential treatment can be performed while preventing electric shock, and an extremely safe and functional electric carpet with electric potential treatment device can be realized. .
