Next, the operation and effect of the control apparatus of the thermal mat heated by the DC power supply according to the embodiment of the present invention configured as described above will be described.

First, the first connector 50 is connected to connect a and a ', b and b', c and c ', d and d', e and e ', and f and f', and then the power supply unit 10 When the main switch SW of the switch is turned on, the voltage is dropped to the secondary coil of the down transformer T1 by dropping the AC power supply to a predetermined level in the down transformer T1, and inducing the down transformer T1. The voltage induced in the secondary coil of) is full-wave rectified by the first full-wave rectifying means 12 to a DC voltage.

The DC voltage full-wave rectified by the first full-wave rectifying means 12 is output through the output resistor R2 to filter the noise included in the DC voltage by the capacitor C1 to smooth through the reverse current prevention diode D1. Output to the capacitor (C2), and smoothed in the smoothing capacitor (C2) outputs a constant level constant voltage from the constant voltage means (14).

In order to stably operate the control device of the thermal mat heated by the DC power supply of the present invention, when the main switch SW is turned off, the reverse current flows due to the charge charged in the smoothing capacitor C1. A negative bias voltage (discharge voltage of C1) is blocked through the bias resistor R1 at the base end of the transistor Q1 when the main switch SW is turned off. It is applied through R1 to switch on transistor Q1 to bypass charge charged in smoothing capacitor C2 to ground.

As described above, when the first temperature setting means 20 including the selector switch located at the OFF stage is operated in the state where the constant voltage of the constant voltage is output from the constant voltage means 14, the bias resistance ( The voltage of the output terminal of the constant voltage means 14 is applied as a bias voltage to the base terminal of the transistor Q2 through R3 so that the transistor Q2 is switched on, and the voltage across the resistors R14 to R24 is It is applied to the inverting terminal (-) of the comparator 32 constituting the first temperature control means 30, in the comparator 32 is applied to the voltage and non-inverting terminal (+) applied to the inverting terminal (-) When the voltage applied to the inverting terminal (-) is large by comparing the reference voltage, the output terminal of the comparator 32 has a high level pulse according to the output resistance (R14-R24) value of the first temperature setting means 20. Bias by varying the width of the signal The current flows through the current limiting resistor R30 to the first photodiode 34a of the phototriac 34 by switching on the transistor Q13 through the resistor R29, and at this time, the current limiting resistor R31. Since the current flows through the optical triac 34b to conduct the first photo triac 34, a trigger current is applied to the gate terminal of the first triac 36, so that the first triac 36 It is conducting.

Accordingly, since the AC power is applied to the second full-wave rectifying means 40, the AC power is full-wave rectified to the DC power in the second full-wave rectifying means 40 and smoothed in the smoothing capacitor C5, and then a single thermal mat ( DC current flows to the first heating wire 202 through the first bimetal 204 installed in the 200 to radiate infrared rays and far infrared rays from the single heating mat 200 to heat the user's body to treat pain and bruises. At the same time, blood vessels can be expanded to promote blood circulation.

As described above, when the temperature in the single heating mat 200 reaches the temperature set by the first temperature setting means 20 as a current flows in the first heating wire 202 in the single heating mat 200, The first bimetal 204 is turned off to prevent heating above a set temperature, and sparks generated when the first bimetal 204 is turned off are filtered by the capacitor C6, and the first bimetal 204 is also filtered. When overheated due to the inoperability of 204, the temperature of the comparator 32 is detected by applying the temperature to the comparator 32 by the first dummy 208 installed in the single heating mat 200. As the low level signal is output from the output terminal, the transistor Q13 is turned off so that the second propagation current means 40 does not receive an AC voltage.

Therefore, since no current flows in the first heating wire 202 in the single heating mat 200, not only the single heating mat 200 can be prevented from being overheated, but also a fire caused by overheating can be prevented. have.

In the above description, the case where the first temperature setting means 20 is set in the first stage has been described as an example. However, when the temperature in the single heating mat 200 is to be increased in a short time, the second stage and the third stage It is possible to set up to 11 steps, and it is designed to increase the temperature by 5 ° C for each step, but it is not necessarily limited thereto. For example, the temperature is increased by 3 ° C or 10 ° C for each step. It may be designed to increase.

When the sixth stage is set by the first temperature setting means 20, the constant voltage of the output terminal of the constant voltage means 14 of the power supply unit 10 is connected to the bias terminal of the transistor Q7 through the bias resistor R8. Since the transistor Q7 is switched on, the voltage applied to the resistors R18-R24 is applied to the inverting terminal (-) of the comparator 32 so that the voltage width of the high level is variable at the output terminal of the comparator 32. The switching-on time is varied by outputting the transistor Q13 according to the output resistances R18-R24 set in the sixth stage by the first temperature setting means 20. As described above, the first phototriac 34 is controlled. And switching on the first triac 36 to full-wave rectifying AC power by the second full-wave rectifying means 40 to the first heating wire 202 of the single thermal mat 200. Transistors Q13, the first phototriac 34 and the first triac 36 DC power flows during the switching-on time to heat the single thermal mat 200 to emit infrared rays and far infrared rays.

Since the first temperature setting means 20 is set to 2 to 5 stages and the first temperature setting means 20 to 7 stages to 11 stages, it is the same as the case of setting to 1 stage and 6 stages. , Duplicate descriptions are omitted. When the transistor Q13, the first phototriac 34 and the first triac 36 of the first temperature control means 30 are switched on, the set end of the first temperature setting means 20 is increased. The pulse width output from the comparator 32 of the said 1st temperature control means 30 becomes wider and longer (as it goes up to 11 steps than 1 step).

On the other hand, when the potential is applied to a pain area or a bruised area of the user to treat the pain, the first switching means SW1 of the first potential output control unit 60 is switched on and the first timer ( When the time is set between 1 second and 70 minutes by activating 62), the time set by the first time constant circuit 63 is set, and at this time, a current is applied to the light emitting diode LED1 of the first display means 64. Since the current flows through the limiting resistor R35, the light emitting diode LED1 of the first display means 64 emits light, and the potential is output from the first potential generator 206 provided in the single thermal mat 200. It is displayed.

Specifically, when the first timer 62 starts counting the time, the light emitting diode LED1 of the first display means 64 emits light and at the same time, the second of the second phototriac 66. Since the current flows through the current limiting resistor R36 to the photodiode 66a, the second photodiode 66a emits light, and accordingly, the second optical triac 66b is turned on so that the second phototriac 66 is conducted. At the same time as the switching-on, a trigger signal is input to the gate terminal of the second triac 68 so that current flows through the current limiting resistor R37 to the second triac 68.

At this time, AC power is applied to the primary coil of the first boost transformer T2, and a high voltage is induced to the secondary coil of the first boost transformer T2, so that the first timer 62 of the potential output control means 60 is applied. The potential signal is output from the first potential generating means 206 installed in the single thermal mat 200 during the time set by the negative electrode, and applied to the pain area of the user to treat pain caused by bruise.

The power supply unit 10, the first temperature setting means 20, the first temperature control means 30, and the first full-wave rectifying means in the control apparatus of the thermal mat heated by the DC power source according to the second embodiment of the present invention ( 40, the first heating wire 202, the first bimetal 204, the first potential generator 206, and the double heating mat 300 by the first connector 50 and the first potential output control means 60. Since the operation of the first dummyster 208 has already been described in the description of the control apparatus of the thermal mat heated by the DC power supply according to the first embodiment of the present invention, redundant description is omitted here.

First, the first connector 50 is connected to connect a and a ', b and b', c and c ', d and d', e and e ', and f and f', and the second connector ( 150) to connect p and p ', q and q', r and r ', s and s', t and t ', u and u', and then the main switch SW of the power supply unit 10. When switching on, the voltage is dropped to the secondary coil of the down transformer T1 by dropping the AC power to a constant level in the down transformer T1, and inducing the secondary coil of the down transformer T1. The rectified voltage is full-wave rectified by the first full-wave rectifying means 12 to a DC voltage.

The DC voltage rectified by the first full-wave rectifying means 12 is output through the output resistor (R2) to filter the noise included in the DC voltage by the capacitor (C1) constant voltage through the reverse current prevention diode (D1) The constant voltage means 14 outputs a constant voltage at a constant level.

In order to stably operate the control device of the thermal mat heated by the DC power supply of the present invention, when the main switch SW is turned off, the transistor Q1 is discharged to discharge the charge charged in the smoothing capacitor C2. A negative bias voltage (discharge voltage of the capacitor C1) is applied through the resistor R1 to the base terminal through the resistor R1 to switch on the transistor Q1 to the smoothing capacitor C2. Bypass the charged charge to ground.

As described above, when the constant temperature means 14 outputs a constant level of constant voltage, the second temperature setting means 120 located at the OFF stage is operated to set the voltage at the first stage. The voltage of the output terminal of the constant voltage means 14 is applied to the base terminal of the transistor Q2 as a bias voltage so that the transistor Q2 is switched on, and the voltage applied to the resistors R14 to R24 is controlled by the second temperature control. It is applied to the inverting terminal (-) of the comparator 132 constituting the means 130, the comparator 132 compares the voltage applied to the inverting terminal (-) and the reference voltage applied to the non-inverting terminal (+) When the voltage applied to the inverting terminal (-) is large, the output terminal of the comparator 132 has a width of a high level pulse signal according to the output resistance (R14-R24) value of the second temperature setting means 120. Variable output and output through bias resistor (R59) The current flows through the current limiting resistor R60 to the third photodiode 134a of the third phototriac 134 by switching on the jitter Q51, and at this time, the third limiting resistor R61 passes through the current limiting resistor R61. Since the current flows through the optical triac 134b and the third phototriac 134 is conducted, the trigger current is applied to the gate terminal of the third triac 136, so that the third triac 136 is conducted. .

Accordingly, since the AC power is applied to the third full-wave rectifying means 140, the AC power is full-wave rectified by the third full-wave rectifying means 140 to DC power and smoothed in the smoothing capacitor C15, and then double warm mat ( DC current flows to the second heating wire 302 through the second bimetal 304 installed in 300 to radiate infrared rays and far infrared rays from the right side of the double heating mat 300 to heat the user's body to treat pain and bruises. At the same time, blood vessels can be expanded to promote blood circulation.

As described above, when the temperature in the double heating mat 300 reaches the temperature set by the second temperature setting means 120 as a current flows in the second heating wire 302 in the double heating mat 300, The second bimetal 304 is turned off to prevent it from being heated above the set temperature, and sparks generated when the second bimetal 304 is turned off are filtered by the capacitor C16, and further, the second bimetal 304 is filtered. When overheated due to the inoperability of the 304, the temperature is detected by the second dummyster 308 installed in the double heating mat 300 and applied to the comparator 132 to determine the temperature of the comparator 132. Since the transistor Q51 is turned off because the low level signal is output from the output terminal, the third phototriac 134 and the third triac 136 do not operate. Therefore, the third propagation current means 140 has an AC voltage. Is not authorized All.

Therefore, since no current flows in the second heating wire 302 in the double heating mat 300, the double heating mat 300 can be prevented from being overheated, and the occurrence of a fire due to overheating can be prevented. have. In the above description, when the temperature of the single and double thermal mats 200 and 300 is lower than a set temperature, a high level pulse signal of which the width is modulated is output to the output terminal of the comparator 132 so that the single and double thermal mats are output. It goes without saying that a current flows through the second heating wires 202 and 302 in the 200 and 300.

In the above description, the case where the second temperature setting means 120 is set in the first stage has been described as an example. However, when the temperature in the double heating mat 300 is to be increased in a short time, the second and third stages may be used. It is possible to set up to 11 steps, and it is designed to increase the temperature by 5 ° C for each step, but it is not necessarily limited thereto. For example, the temperature is increased by 3 ° C or 10 ° C for each step. It may be designed to increase.

When the sixth stage is set by the second temperature setting means 120, the constant voltage of the output terminal of the constant voltage means 14 of the power supply unit 10 is connected to the bias terminal of the transistor Q7 through the bias resistor R8. Since the transistor Q7 is switched on, the voltage applied to the resistors R18-R24 is applied to the inverting terminal (-) of the comparator 32, so that a high level with a wide pulse width is applied to the output terminal of the comparator 32. Is outputted to switch on the transistor Q51 to switch on the second phototriac 134 and the second triac 136 as described above to propagate the AC power in the third full-wave rectifying means 140. The rectification is performed so that a direct current power flows through the second heating wire 302 of the double heating mat 300 to heat the double heating mat 300 to emit infrared rays and far infrared rays.

Since the second temperature setting means 120 is set in the second stage to the fifth stage and the second temperature setting means 120 in the seventh stage to the eleventh stage, it is the same as when it is set in the first stage or the sixth stage. , Duplicate descriptions are omitted.

On the other hand, when the potential is applied to the pain area or the bruised area of the user to treat the pain, the second switching means SW2 of the second potential output control unit 160 is switched on and the second timer ( When the time between 1 second and 70 minutes is set by operating 162, the time set by the second time constant circuit 163 is set, and at this time, a current is applied to the light emitting diode LED2 of the second display means 164. Since a current flows through the limiting resistor R65, the light emitting diode LED2 of the second display means 164 emits light, and the potential is output from the second potential generator 306 provided in the double warm mat 300. It is displayed.

Specifically, when the second timer 162 starts to count the time, the light emitting diode LED2 of the second display means 164 emits light and the fourth of the fourth phototriac 166. Since the current flows through the current limiting resistor R66 to the photodiode 166a, the fourth photodiode 166a emits light, and thus the fourth optical triac 166b is turned on to conduct the fourth phototriac 166. At the same time as the switching-on, a trigger signal is input to the gate terminal of the fourth triac 168 so that current flows through the current limiting resistor R67 to the fourth triac 168.

At this time, since the AC voltage is applied to the primary coil of the second boosting transformer T3 and the high voltage is induced to the secondary coil, the potential of the second potential generator 306 installed in the double warm mat 300 is set for a predetermined time. Output is applied to the user's bruises or pain areas to treat the pain, and at the same time promotes blood circulation by the infrared and far infrared rays radiated from the double thermal mat (300).

In the above description, the first and second potential generators are described in detail in Utility Registration No. 0236007, filed and registered on March 14, 2001 by the present applicant, and thus the detailed description thereof will be omitted.

In the above description, the specific embodiments have been shown and described, but the present invention is not limited thereto, for example, by those skilled in the art without departing from the concept of the present invention. Of course, the design can be changed in various ways.

In addition to the application of infrared rays and far infrared rays at the same time there is an excellent effect that can be applied to the potential to promote blood circulation by the heat and potential treatment.
