Description

  The present invention relates to a thermal treatment device that gives a thermal effect to a user by being supplied with electric power.

In recent years, various electric mats that give a thermal effect or a potential effect to a user when electric power is supplied have been used (see, for example, Patent Document 1).
Thermal therapy devices such as the electric mat described in Patent Document 1 often include a control device for adjusting the output temperature. The user can adjust the output temperature of the thermotherapy device to a desired temperature by operating the control device.

The output temperature is controlled by the method of outputting the output temperature according to the slider knob position to the thermotherapy device, the method of outputting the output temperature according to the amount of rotation of the dial to the thermotherapy device, the heat increase button / heat For example, a method of changing the output temperature stepwise by pressing the decrease button.
If the control device is provided with a slider or a dial, the control device becomes larger due to the length of the slider, the thickness of the dial, or the like. Therefore, when it is desired to downsize the control device, it is preferable to use temperature control by button operation.

  Further, the control device changes the output temperature by one step when the button is clicked once. However, in this control method, when a multi-stage change is desired, the user needs to hit the button a plurality of times. Therefore, the control device normally performs the same operation as the operation when the button is continuously clicked when the button is pressed for a long time. As a result, the user can easily change the output temperature in multiple steps by pressing and holding the button.

A main body laid under a user, an electric wire provided in the main body and generating energy by supplied electric power, and the electric A power supply device for supplying power to the line, and a control device for controlling the output of the power supply device, wherein the control device is pressed for a predetermined time with an output increase button for increasing the output of the power supply device when pressed. When it continues, it is a thermotherapy device provided with the output limiting part which reduces the output voltage of the said power supply device.

  In the present invention, the electric wire is a heater wire that generates thermal energy by supplied electric power.

  Further, in the present invention, the output limiting unit stops the output of the power supply device when the output increase button is continuously pressed for a predetermined time.

  According to the present invention, the output control unit of the control device decreases the output voltage of the power supply device when the output increase button is continuously pressed for a predetermined time. Thereby, it is possible to prevent the thermotherapy device from unintentionally entering a high output state.

Next, the operation of the thermotherapy device 1 will be described.
FIG. 3 is a flowchart showing the operation of the thermotherapy device.
When the user presses the power button 231 on the operation panel 23 of the controller 20, the power supply unit 211 of the power supply device 21 extracts power from the AC power supply and supplies power to the main body 10 and the controller 20.
The input determination unit 222 of the control device 22 determines whether or not an operation signal is generated when the buttons 232 to 235 on the operation panel 23 are pressed (step S1). When the input determination unit 222 inputs an operation signal via the input unit 221 (step S1: YES), the input determination unit 222 detects the presence / absence of the operation signal every 8.912 milliseconds, and whether the operation signal has continued for 60 milliseconds or more. By determining whether or not, it is determined whether or not the input of the operation signal is noise due to chattering (step S2).

If the input determination unit 222 determines that the input of the operation signal has not continued for 60 milliseconds or longer, the input determination unit 222 determines that the input of the operation signal is noise due to chattering (step S2: YES), returns to step S1, and performs the operation again. Wait for signal input.
On the other hand, if it is determined that the input of the operation signal has continued for 60 milliseconds or more, the input determination unit 222 determines that the operation is a button operation by the user (step S2: NO), and is the timer unit 223 measuring time? It is determined whether or not (step S3). By this. The input determination unit 222 determines whether any button on the operation panel 23 is being pressed.

  If the input determination unit 222 determines that the timer unit 223 does not measure time (step S3: NO), the input determination unit 222 activates the timer unit 223, and the timer unit 223 measures the elapsed time from the current time. Start (step S4). Next, the control device 22 executes control processing according to the operation signal input by the input determination unit 222, and outputs a voltage control signal to the power supply device 21 (step S5). Specifically, the following processing is performed.

When the operation signal input by the input determination unit 222 indicates “potential increase”, the input determination unit 222 indicates that the voltage currently output from the power supply device 21 to the potential line 11 is a predetermined maximum output voltage amount (for example, 800 V). ). When the current voltage is the maximum supply voltage amount, the input determination unit 222 ends the process without outputting the operation signal. On the other hand, when the current voltage is less than the maximum supply voltage amount, the input determination unit 222 outputs an operation signal indicating an increase in potential to the potential line power control unit 224. Next, the potential line power control unit 224 uses a voltage obtained by adding a predetermined voltage (for example, 50 V) for one stage to the voltage that the power supply device 21 is currently outputting to the potential line 11. Is output to the potential line power supply unit 212 of the power supply device 21.
When the operation signal input by the input determination unit 222 indicates “potential decrease”, the input determination unit indicates that the voltage currently output from the power supply device 21 to the potential line 11 is a predetermined minimum output voltage (for example, 200 V). It is determined whether or not. When the current voltage is the minimum supply voltage amount, the input determination unit 222 ends the process without outputting the operation signal. On the other hand, when the current voltage is larger than the minimum supply voltage amount, the input determination unit 222 outputs an operation signal indicating a potential decrease to the potential line power control unit 224. Next, the potential line power control unit 224 controls the voltage that causes the potential line 11 to output a voltage obtained by reducing a voltage for one predetermined stage to the voltage that the power supply device 21 currently outputs to the potential line 11. The signal is output to the potential line power supply unit 212 of the power supply device 21.
In addition, when the operation signal input by the input determination unit 222 indicates “electrical heat increase”, when the operation signal input by the input determination unit 222 indicates “potential increase”, The voltage control signal is output to the heater wire power supply unit 213 of the power supply device 21 by the same process as that shown in FIG.

  On the other hand, when the input determination unit 222 determines that the timer unit 223 is measuring time (step S3: YES), the timer unit 223 determines whether or not 30 seconds have elapsed. Determination is made (step S6). As a result, the timer unit 223 determines whether any button on the operation panel 23 remains pressed for a long time. When the timer unit 223 determines that the measurement time is within 30 seconds (step S6: NO), the control device 22 executes control processing according to the operation signal input by the input determination unit 222, and the power supply device 21. A voltage control signal is output to (step S5).

  On the other hand, when the timer unit 223 determines that the measurement time has passed 30 seconds (step S6: YES), the timer unit 223 outputs a trigger signal to the output limiting unit 226. When receiving the trigger signal from the timer unit 223, the output control unit 226 determines whether or not the operation signal input by the input determination unit 222 indicates an increase in heat (step S7). When the output control unit 226 determines that the operation signal does not indicate an increase in heat (step S7: NO), the control device 22 executes control processing according to the operation signal input by the input determination unit 222, and A voltage control signal is output to the device 21 (step S5).

  On the other hand, when the output control unit 226 determines that the operation signal indicates an increase in heat (step S7: YES), the output control unit 226 keeps the heat increase button 234 unintentionally pressed. It is determined that the power supply is interrupted, and a cutoff request signal for requesting cutoff of power supply to the heater wire is output to the heater wire power control unit 225 (step S8). Accordingly, the heater line power control unit 225 outputs a voltage control signal for cutting off the power supplied to the heater line to the heater line power supply unit 213 of the power supply device 21, and the heater line power supply unit 213 supplies the heater line to the heater line. Shut off the power to be used. Further, the control device 22 does not accept the operation of the buttons 232 to 235 other than the power button 231 by the operation panel 23 thereafter. Thereby, the thermotherapy device 1 can prevent unintentionally increasing the output to the heater wire.

  When the control device 22 performs a control process in step S5, or when the heater wire power control unit 225 outputs a cutoff request signal in step S8, the controller 20 determines whether the power button 231 has been pressed by the user. It is determined whether or not (step S9). If the controller 20 determines that the power button 231 has not been pressed (step S9: NO), the controller 20 returns to step S1 and waits for an operation signal to be input. On the other hand, when the controller 20 determines that the power button 231 has been pressed (step S9: YES), the power supply unit 211 cuts off the power supply from the AC power supply and ends the power supply to the main body 10 and the controller 20. .

In addition, when the input determination unit 222 determines that no operation signal is input in step S1 (step S1: NO), the timer unit 223 stops time measurement, and the input determination unit 222 inputs the operation signal. Wait (step S10).
Thus, according to the present embodiment, the output control unit 226 of the control device 22 reduces the output voltage of the power supply device 21 when the heat increase button 234 is kept pressed for a predetermined time. Thereby, it is possible to prevent the thermal treatment device 1 from unintentionally entering a high output state.

For example, when the heat increase button 234 for increasing the voltage supplied to the heater wire 12 is kept pressed for a predetermined time, the output with the minimum power may be continued without interrupting the power.
In addition, the power supplied to the potential line 11 is cut off when the potential increase button 232 for increasing the voltage supplied to the potential line 11 is kept pressed for a predetermined time. Also good.

  Moreover, although this embodiment demonstrated the case where the thermal energy of the heater wire 12 was controlled by controlling the output voltage of the power supply device 21, it is not restricted to this. For example, the heat energy of the heater wire 12 may be controlled by controlling the output frequency of the power supply device 21 by using the heater wire 12 whose thermal energy to be output varies depending on the frequency of input electricity. In this case, when the heat increase button 234 is pressed, the frequency of electricity output from the power supply device 21 to the heater wire 12 increases, and when the temperature decrease button 235 is pressed, the frequency of electricity output from the power supply device 21 to the heater wire 12 decreases. To do. Further, in this case, the output limiting unit 226 cuts off the power supplied to the heater wire 12 or reduces the frequency to be supplied when the heat increase button 234 is kept pressed for a predetermined time.

  In the present embodiment, the case where the thermotherapy device 1 includes the potential wire 11 and the heater wire 12 has been described. However, the present invention is not limited to this. For example, the thermotherapy device 1 may further include a magnetic coil. Only the heater wire 12 may be provided.

  Moreover, although this embodiment demonstrated the case where the thermotherapy device 1 was provided with the main body 10 and the controller 20 separately, it is not restricted to this, Even if each apparatus which comprises the thermotherapy device 1 is integrated. good.

  In this embodiment, the input determination unit 222 of the control device 22 detects the presence / absence of an operation signal every 8.912 milliseconds, and determines whether or not the operation signal has continued for 60 milliseconds or more by chattering. Although the case where it was determined whether it is noise was demonstrated, it is not restricted to this. Moreover, although the case where the timer unit 223 outputs the trigger signal when the input of the operation signal continues for 30 seconds has been described in the present embodiment, the present invention is not limited to this.
