2. Description of the Related Art Conventionally, as shown in FIG. 14, an electric potential therapeutic device 6 used for treating stiff shoulders, headaches, insomnia, and the like.
There was 7. The principle of this effect is that when a patient with the above-mentioned disease is placed at a high potential (about 300 to 1000 volts), the ionization of sodium and calcium in the circulating blood is increased, thereby alkalizing the acidified human body,
It is to restore the human body to a normal state. This electric potential treatment device 6
A heat-sensitive heater wire 6 is arranged in the center of the inside of 7. As shown in FIG. 15, the heat-sensitive heater wire 6 includes a heater wire 10, a heat-sensitive layer 11 whose impedance changes according to the temperature of the heater wire 10, and a temperature control box 7 whose change will be described later. The signal wire 12 for transmitting to the control section, the core thread 13 for preventing the wires from being crushed, and the heat-resistant outer skin 14 for preventing damage to the above-mentioned respective components. The temperature control box 7
Is a temperature control device in which the user turns the power on and off and sets the temperature, and is provided with a power switch, a temperature adjustment dial 9, and the like.

In the potential treatment device 67 having such a structure, a high potential is applied to the patient by applying a high voltage to the heat-sensitive heater wire 6. In addition, the electric potential treatment device 67 has a function of energizing the heater wire 10 to keep the futon at the set temperature when the user sets a desired temperature with the temperature adjustment dial 9 and turns on the power. It was

On the other hand, in order to change the feel and the like of the futon,
There was a thing that I could change the cover attached to the futon. The replacement cover was configured so that it could be easily attached to and removed from the futon by a fastener, a hook, or the like. As the replacement cover, there was a side cloth formed of a material such as cotton cloth, cotton blanket, towel cloth or wool boa cloth.

Further, in order to change not only the electric potential treatment but also the feel and the like of the surface of the futon, it is considered that the futon of the electric potential therapeutic device 67 uses the above-mentioned replacement pad.

[0006]

However, when a user uses such an electric potential therapeutic device by exchanging the cover, when the temperature of the heater is set to the same temperature as shown in FIG. Due to the difference in heat transfer characteristics of the top cover, the surface temperature of the futon top contacted by the user is different. For example, there is a difference in temperature between the surface temperature of the side material A of the thin cloth as the cover and the surface temperature of the thick material side material C such as the wool boa. And this temperature difference is the temperature at which people clearly feel the difference in temperature and temperature, and when the user replaces the side material as a veneer, the user sets the heater so that the surface temperature of the side material is the same. It became necessary to adjust the control temperature. In this case, as shown in FIG. 5, in order to make the surface temperatures of the side ground A and the side ground C the same, Va for the side ground A and Vc for the side ground C respectively. It was necessary to raise the heating temperature of. In order to raise this temperature, the temperature control knob is appropriately operated, but there is a problem that the desired temperature cannot be set immediately. Note that Ta and Tc in FIG. 16 indicate the difference between the surface temperature of each side and the temperature of the heater.

The present invention has been made in order to solve the above-mentioned problems, and for a replaceable cover, the thermal bed which can always make the surface temperature of the cover and the set temperature match. The purpose is to provide.

The same components as those of the conventional technique are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 1, the thermoelectric potential therapeutic device of the first embodiment comprises a futon body 1 having a thermosensitive heater wire 6 which is a thermoelectric floor, and a temperature control box 7. In addition, three paddings that are exchanged and attached to the futon body 1, that is, side A made of a thin cotton cloth, side B of a towel cloth, and a boa cloth having a wool foot of about 8 mm. Side land C is prepared.

At the center of the futon body 1, a heat-sensitive heater wire 6 capable of exerting both effects of heat and potential treatment is installed. The heat sensitive heater wire 6 is a heater 10

A desired coat can be attached to the futon body 1 for use.

The temperature control box 7 is a temperature control device for the user to turn the power on and off and set the temperature, and is different from the power switch, the temperature control dial 9 as the temperature setting means, and the normal operation section. And a changeover switch 8 as a selection unit arranged in the.

Next, the electrical circuit configuration of the temperature control section of the first embodiment will be described with reference to FIG. FIG. 2 is a circuit diagram showing the configuration of the temperature controller of the thermoelectric potential therapeutic device.

The circuit housed in the temperature control box 7 includes a temperature detector 15 for detecting the temperature of the heater 10, a temperature setting unit 16 for setting the temperature heated by the heater 10. The heater 10 includes a microcomputer 20 as a control means for controlling the heater 10 so that the temperature of the heater 10 is set by the temperature setting unit 16, a reset circuit 21, and the changeover switch 8. . In the temperature detector 15, the impedance of the temperature sensitive layer 11 changes due to the heat generated by the heater 10, and the current of the signal line 12 accompanying the change is converted into a DC voltage as the temperature of the heater 10 to detect the detected temperature. The signal Vt is output to the microcomputer 20. In the temperature setting unit 16, Vcc is divided by the resistors 31 and 32 and the variable resistor 17 connected to the temperature adjustment dial 9 operated by the user, and the divided voltage value is used as the set temperature signal Vr. Is output to the microcomputer 20.

The microcomputer 20 has a built-in ROM in which a program for controlling the main body of the apparatus is stored.
Upon receiving the power supply from the power supply c and further receiving the reset signal from the reset circuit 21, the program is executed.

In the microcomputer 20, the detected temperature signal Vt of the temperature detector 15 is compared with the set temperature signal Vr from the temperature setting section 16 to obtain Vr>.
In the case of Vt, the L signal is output from the OUT terminal of the microcomputer 20 to turn on the drive transistor 18, and the power control element 19 is turned on accordingly. on the other hand,
When Vr ≦ Vt, the H signal is output from the OUT terminal to turn off the drive transistor 18, and accordingly the power control element 19 is turned off.

In this way, the temperature of the heater 10 is controlled so as to reach the temperature set by the temperature setting section 16. The microcomputer 20 receives the RAM for temporarily storing variables and the like when executing the program, the temperature signals Vr, Vt, and the state of the changeover switch 8, and the drive transistor 18 It has a built-in I / O port that outputs signals.

Next, the operation of the first embodiment will be described with reference to the flowchart of FIG.

Here, the case where the side cloth A is worn as a cover on the futon body 1 will be described. The user first depresses the power switch 22 of the temperature control box 7. Then, the reset signal of the reset circuit 21 is input to the microcomputer 20, and the microcomputer 20 initializes the built-in RAM and the input / output port (step 1, hereinafter, step is represented by S). Next, the microcomputer 20 reads the state of the changeover switch 8 (S3), and determines whether the read state of the changeover switch 8 is A, B, or C (S).
5). When the changeover switch 8 is A, Va is read from the built-in ROM as temperature data (S7a), and when the changeover switch 8 is B, Vb is built-in R as temperature data.
Read from OM (S7b), changeover switch 8 is C
In the case of, Vc is read from the built-in ROM as temperature data (S7c). In this case, Va is read as the temperature data.

Next, the microcomputer 20 reads the set temperature signal Vr set by the temperature adjusting dial 9 (S9), adds the temperature data Va to the set temperature signal Vr, and calculates the corrected temperature Vra ( S1
1). Thereafter, the microcomputer 20 reads the detected temperature signal Vt of the heater 10 output from the temperature detector 15 (S13), and the detected temperature signal Vt and the S
The correction temperature Vra calculated in the processing step 11 is compared (S15). When the corrected temperature Vra is higher than the detected temperature signal Vt (YES in S15), the surface temperature of the side material A attached to the futon does not reach the set temperature set by the temperature adjustment dial 9, so that the heater is used. 10
An L signal is output to the transistor so as to continue the heating of (S17), and thereafter, the processing shifts to the processing step of S3. On the other hand, when the corrected temperature Vra is lower than or equal to the detected temperature signal Vt (N in S15
O), since the surface temperature of the side material A attached to the futon has reached the set temperature set by the temperature adjustment dial 9, an H signal is output to the transistor 18 in order to stop the heating of the heater 10. (S19), the process proceeds to S3.

The processing steps of S3 to S7a, 7b, 7c function as a selection section, and the processing step of S11 functions as a corrected temperature generation section.

As shown in FIG. 16, the temperature data Va and Vc are set to values that compensate for the temperature decrease Tc and Ta due to each side. Therefore, FIG.
As shown in, the side ground surface temperature in the temperature control depending on the case where the side switch C is used to set the changeover switch 8 to C and the case where the side side A is used to set the changeover switch 8 to the A position. Therefore, the user can save the labor of operating the temperature adjustment dial 9 by matching the position setting of the changeover switch 8 with the replacement side ground even if the side ground as a cover is exchanged.

Further, the changeover switch 8 of the first embodiment

Further, the operation knob of the changeover switch 8 is recessed with respect to the surface on which it is arranged so that the setting is not switched unintentionally.

Next, a thermoelectric potential therapeutic device of the second embodiment in which the thermoelectric potential therapeutic device of the first embodiment is constituted only by an electric circuit instead of the microcomputer 20 will be described with reference to FIG. The same components as those of the thermoelectric potential treatment device of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In FIG. 6, a simple comparison circuit 24 is used as the control means instead of the microcomputer 20.

The temperature setting unit 16 is composed of a series circuit of a resistor 31, a variable resistor 17, and a resistor 32. Further, the temperature setting unit 16 is a different resistor for setting the temperature data for each of the multipliers. A resistor 39 for the side ground A, a resistor 38 for the side ground B, and a resistor 33 for the side ground C are connected so as to be selectable by the changeover switch 8.

Next, the operation of the second embodiment will be described with reference to FIG. Here, a case where the side ground A is attached to the futon body 1 will be described.

First, the changeover switch 8 is set to the position A and the power is turned on. Then, Vcc is divided by the combined resistance composed of the resistor 39, the resistor 32, and the variable resistor 17, and the resistor 31, and the divided voltage value is supplied to the comparator 24 as the correction temperature. It is input as Vr. On the other hand, the temperature of the heater 10 detected by the temperature detector 15 is input to the comparator 24 as Vt. In the comparator 24, when Vr> Vt, the power control element 1
9 is turned on and heating of the heater 10 is continued. On the contrary, when Vr ≦ Vt, the power control element 19 is turned off,
The heating of the heater 10 is stopped. In this way, it is possible to perform temperature control in which the correction temperature of the side ground as the overlay is added. It should be noted that the changeover switch 8 can be similarly controlled for the B position and the C position.

As is clear from the above description, according to the thermoelectric potential therapeutic device of the second embodiment, the lateral regions A,
From the different resistors 33, 38, 39 for setting the temperature data for each of B and C, select the resistor corresponding to the side ground attached to the futon body 1 by the changeover switch 8. Since the resistor is connected to the variable resistor 17 to create the temperature to be corrected, the portion for creating the temperature to be corrected can be downsized and can be implemented at low cost.

The display surface is configured to be able to display characters, numbers, etc. of A, B, and C for the overlay setting. The user can select the top cover with the push switch 40 while confirming the display of the top cover selection displayed on the display device 26.

Next, the electrical circuit configuration of the third embodiment will be described with reference to FIG. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

In the third embodiment, since the push switch 40 is used as the selecting section as described above, the selected state cannot be expressed by the mechanical position change. Therefore, in order to express the selection state, the display device 26 using the LCD
Is displayed using.

Since the LCD display device 26 cannot be directly driven by the general output port terminal of the microcomputer 20, it is connected to the microcomputer 20 via the LCD controller IC 25.

Further, since it is necessary to always hold the selected state, the EEPROM 27 capable of holding the current selected state without supplying power is connected to the microcomputer 20.

Next, the selection operation in the third embodiment will be described with reference to FIG.

The user replaces the side cloth as the upper cover of the futon body 1 and adjusts the temperature control box 7 according to the side cloth.
The push switch 40 is operated. When the push switch 40 is pressed, the microcomputer 20 changes the currently selected selection state to the next selection state and causes the display device 26 to display the selected state. And push switch 4
Each time 0 is pressed, the selection state of the side ground changes in order, and the microcomputer 20 changes the display signal output to the LCD controller 25, and the display of the display device 26 is changed from A → B.
→ Change in the order of C → A ... The user can confirm the display on the display device 26 and select a state suitable for the lateral areas A, B, and C attached to the futon body 1.

At this time, the set selection state is EEPR.
The selected state that is stored in the OM 27 and is set is held until the push switch 40 is pressed next time. This allows the user to push the push switch 4 each time the power is turned on.
There is no need to press 0.

Since the correction temperature control operation is the same as that of the first embodiment, its explanation is omitted here.

Information on the hole of the connection plate 62 can be detected by the light emitting diode 52 and the phototransistor 53. Two sets of the light emitting diode 52 and the phototransistor 53 are arranged in the connector 65. The phototransistors 53 are connected to the terminals I and J of the microcomputer 20 shown in FIG.
