[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show the structure and appearance of an infrared treatment device in a state where the treatment is carried out by holding the infrared treatment device of the present invention in a hand. The grip part 3 is attached to the part 2. The infrared irradiator 2 includes a coil case 6, a ceramic heater 5 coated with a far-infrared radiating substance, and a blower fan 7 in the cylindrical case 4.
An outlet (irradiation) grill 8A is attached to the front end, and an inlet grill 8B is attached to the rear end.

The grip portion 3 made of a resin member contains an electric component for operating the infrared irradiating portion 1 as shown in a circuit diagram to be described later. Has been pulled out. A power switch 10 of, for example, a push-acting type is provided at a central portion on the front side of the grip portion.

When the power switch 10 is turned on, the coil heater 6 and the ceramic heater 5 are energized and generate heat unless there is a failure such as disconnection, and the blower fan 7 is operated by being supplied with power. Therefore, first, the healer receives warm air generated by the heat of the coil heater 6, and then is treated by far infrared rays emitted by the heat generated by the ceramic heater 5.

The power switch 10 is not limited to the push-operation type, but may be an appropriate one such as a vertical slide operation type.

FIG. 3 is a control circuit diagram of the infrared therapy apparatus.

As the control means, a general microcomputer (hereinafter abbreviated as a microcomputer) 15 is used. The power switch 10 described above is connected to the input side of the microcomputer 15.

On the other hand, on the output side of the microcomputer 15, the coil heater 6, the fan motor 7M of the blower fan 7, and the ceramic mixer 5 are controlled by the microcomputer 15 to control relays 17, 18, and 19, respectively. A heater and a blower fan control circuit 13 having a circuit configuration connected in parallel to a power supply 16 of 100 V AC are provided via relay contacts 17b, 18b, and 19b.

That is, the microcomputer 15 outputs the relay coils 17a, 18a, 1
Output lines 12A, 12B, and 12C are provided to be connected to the output coil 9a. For example, when an excitation signal is output to the output line 12A, the relay coil 17a is excited and the relay contact 17b is closed, so that the coil heater 6 is turned on. When the excitation coil 16 generates heat and loses the output of the excitation signal, the relay coil 17a is de-energized, the relay contact 17b is opened, and the power supply 16 is cut off to stop generating heat.

Similarly, when an excitation signal / non-excitation signal is output from the microcomputer 15 to the other control relays 18 and 19 via the output lines 12B and 12C, respectively.
Each of the relay coils 18a and 19a is energized / de-energized,
The opening / closing operation of each relay contact 18b, 19b causes the operation / stop of the blower fan 7 and the heat generation /
Independent control that the stop is performed is performed by the microcomputer 15.

Here, the coil heater 6 or the ceramic heater 5 may be disconnected due to its life. In such a case, the cold wind as described above makes the user uncomfortable or cannot receive the infrared treatment.

In such a case, the infrared therapy device can be used in a suboptimal manner. Next, this will be described in detail.

First, the control circuit includes a ceramic heater 5.
Is provided with a ceramic heater disconnection detection circuit 20 which can detect whether or not is disconnected. Similarly,
A coil heater disconnection detection circuit 28 for detecting disconnection of the coil heater 6 is provided.

These heater disconnection detecting circuits can be formed using, for example, a photocoupler including a light emitting diode and a phototransistor.

For example, in the case of a disconnection detection circuit 20 for a ceramic heater, the light emitting diode 22 of the photocoupler 21 is connected in series to the ceramic heater 5 and is connected between the ceramic heater 5 and the control relay 19. Insert in series. Also, the phototransistor 23 of the photocoupler 21
Has its emitter side grounded and its collect side connected to a 5V DC voltage via a resistor 24.

The resistor 24 and the phototransistor 2
The signal line 25 is taken out from the connection point P1 with the collector 3 and the connection point potential is connected to the microcomputer 15. Note that a diode 26 is connected in parallel to the light emitting diode 22 so that a heater current flows in the opposite direction of the AC power supply.

Therefore, when a heater current flows through the ceramic heater 5 with the AC power supply 16, the light-emitting diode 22 conducts and emits light by the positive-wave current, and the phototransistor 23 that receives the light turns on. A ground potential of 0 V is output to P1. On the other hand, when the heater current is a negative wave current flowing through the diode 26 in reverse, the light emitting diode 22 is non-conductive and does not emit light.
3 is turned off, and 5 V of the DC power supply is output to the connection point P1.

As described above, if the ceramic heater 5 is in a normal state with no disconnection, a signal voltage intermittently changing between 0 V and 5 V as shown in FIG. 4A is output to the connection point P1. You. Therefore, the microcomputer 15 sees the intermittently changing voltage signal input from the signal line 25 at this time,
It is determined that there is no disconnection in the ceramic heater 5.

On the other hand, if the ceramic heater 5 is disconnected, the heater current does not flow.
2 is non-conductive and does not emit light, and the phototransistor 23 is
F, no intermittent signal voltage as in the normal state is output to the connection point P1, and 5 V of the DC power supply is output in a constant state as shown in FIG. Become. Therefore, in this case, the microcomputer 15 determines that there is a disconnection in the ceramic heater 5 by seeing the voltage signal of a constant potential input from this signal line.

As described above, whether an intermittent signal voltage is output to the connection point P1 or a signal of a constant voltage is output,
The ceramic heater disconnection detection circuit 20 can detect disconnection of the ceramic heater 5.

The disconnection detection circuit 28 for the coil heater has the same configuration. A photocoupler 29 composed of a light emitting diode 30 and a phototransistor 31 is inserted between the coil heater 6 and the control relay 17 in series. A signal voltage similar to that shown in FIG. 4 is output from the signal line 34 to the connection point P2, which is connected to the DC potential of 5 V through the resistor 32, depending on whether the coil heater 6 is disconnected or not. This is input to the microcomputer 15.

Accordingly, if an intermittent signal voltage is input from the signal line 34, the microcomputer 15 determines that the coil heater 6 is not disconnected. Determines that the coil heater 6 is disconnected. Reference numeral 33 denotes a diode connected in parallel to the light emitting diode 30 so that a heater current in the opposite direction of the AC power supply 16 flows.

In this manner, the microcomputer 15 takes in the potentials of the connection points P1 and P2 in the respective disconnection detection circuits 20 and 28 from the signal lines 25 and 34 and monitors them, and monitors the signals whose potentials intermittently change to 0V and 5V. If it is a voltage, it is determined that there is no disconnection in the heaters 5 and 6. Also, 5V
If the voltage is constant, it is determined that the heaters 5 and 6 are disconnected.

The result of the determination as to whether or not there is a disconnection of the heater determined by the microcomputer 15 is notified. That is, if there is a disconnection on the output side of the microcomputer 15, the LED 36 emits light and can be lit and displayed.
For example, a disconnection notification means using an indicator light is provided. In this case, the disconnection notification of the ceramic heater 5 and the coil heater 6 is selectively displayed by using one LED 36. Therefore, when the ceramic heater 5 has a disconnection, for example, the LED 36 is blinked and displayed, and when the coil heater 5 has a disconnection. Is LED3
The microcomputer 15 outputs a different control signal to the LED display control line 37 so that the lighting mode can be changed, for example, by keeping the LED 6 continuously (continuously) lit. By changing the lighting state, it is possible to identify and display even one LED 36, thereby obtaining advantages such as a reduction in parts cost. Of course, LE
It is also possible to provide two D36s for the ceramic heater and the coil heater.

Next, a control flow for detecting the disconnection of the heater using the disconnection detecting circuits 20 and 28, controlling the energization of the heater corresponding to the disconnection detection, and changing the treatment content, etc.
This will be described with reference to FIG.

When the control flow starts, it is determined whether the power switch 10 has been pressed (ON) (decision 4).
1) When the power switch 10 is turned on in normal use,
The determination 41 is YES, and it is determined whether or not the next ceramic heater 5 is disconnected (determination 42). If the ceramic heater 5 is not disconnected (judgment 42 is N
O) Next, it is determined whether or not the coil heater 6 is disconnected (decision 43). If there is no disconnection of the coil heater 6 (NO in decision 43), the coil heater 6 is energized (step 44), the ceramic heater 5 is energized (step 45), and the blower fan 7 is operated (O).
N) Perform operation (process 46). First,
The heat of the coil heater 6 is sent by the blower fan 7 as warm air, so that the user does not feel cold, and in the meantime, the ceramic heater 5 that has been rising slowly generates enough heat to emit infrared rays. The original infrared treatment can be received.

When the operation of the treatment is started by pressing the power switch 10 in this manner, from the time when the treatment is started,
An operation of integrating the elapsed treatment time T (infrared irradiation time) by the timer is executed. Here, the treatment time T can be arbitrarily set by a treatment time setting timer or the like, but generally, the irradiation time required for infrared treatment is 10 minutes to 30 minutes, and it is preferable that the irradiation time be completed within that time. Then, the allowable treatment time of 30 minutes, which is the upper limit, is compared with the treatment time (elapsed time) counted by the timer (judgment 4).
7).

Then, if the treatment time T is still within 30 minutes (decision 47 is NO), the process returns to the decision 41, and the operation following the decision 42 to the processing 46 is executed to continue the treatment. However, if the treatment time exceeds 30 minutes (decision 4)
7 is NO), the coil heater 6 and the ceramic heater 5 are de-energized, and the operation of stopping (OFF) all the operations of stopping the blower fan 7 is also executed (process 4).
8).

When the power switch 10 is turned off when the treatment is completed or during the treatment, the judgment 41 is NO, and all the operations are stopped (OFF) at this time. The operation is executed (Step 49).

Next, a description will be given of a control in the case where the coil heater 6 is disconnected by the coil heater disconnection detection circuit 28, although the ceramic heater 5 is not disconnected.
At this time, in the control flow, the judgment 41 is YES, the judgment 42 is NO, and the judgment 43 is YES. Then, an operation of lighting (ON) the LED 36 serving as a heater disconnection notifying means is executed (process 51), and the user is notified that the coil heater 6 is disconnected.

However, in this case, since the ceramic heater 5 is normal (not disconnected), it is possible to receive the infrared ray treatment by this.
After the lighting of, the operation of turning on (energizing) the ceramic heater 5 is executed (process 52).

In these operations, since the 5 V potential signal from the coil heater disconnection detection circuit 28 is input to the microcomputer 15 via the signal line 34 in the circuit diagram of FIG. 3, the microcomputer 15 confirms the disconnection of the coil heater 6. The control signal for continuous lighting is output to the LED display control line 37 to
Is turned on (continuous lighting), the microcomputer 15 outputs an excitation signal to the output line 12C of the ceramic heater 5, and activates the control relay 19 to contact the relay contact 19 thereof.
b is closed, and the ceramic heater 5 is energized and heated.

In this case, the blower fan 7 is not driven at the same time when the ceramic heater 5 is turned on (energized). That is, when the coil heater 6 is disconnected, the blower fan 7 is stopped. In this case, even if the coil heater 6 is useless, the infrared treatment can be performed with the active ceramic heater 6, but the rising of the ceramic heater 5 is slow, so that the ceramic heater 5 is turned on (energized).
At the same time, when the blower fan 7 is driven immediately, a cool wind is sent and the user feels uncomfortable.

Therefore, when the power switch is pressed when the coil heater 6 is disconnected and the coil heater 6 is operated, a judgment 41 is made.
When the judgment is YES and the judgment 42 is NO, and when the judgment 43 is YES and the ceramic heater 5 is turned on (energized), an operation of integrating the elapsed time from that time by a timer is executed (process 53). Then, the elapsed time is constantly monitored to determine whether or not the elapsed time has reached a predetermined time, for example, 5 minutes (determination 54). The term “5 minutes” means a time required for the ceramic heater 5 to generate enough heat to emit infrared rays, that is, a rise time. Therefore, when it is determined that five minutes have passed until the user stands up sufficiently (determination 54 is YES),
An operation of driving (ON) the blower fan 7 for the first time, that is, performing a delay operation such that the blower fan 7 is driven when the ceramic heater 5 generates heat and the blower fan 7 is driven so that no cool wind is generated. . (Process 46).

The operation in this case is also performed by the microcomputer 1 when the microcomputer 15 confirms that 5 minutes have passed in the circuit diagram of FIG.
5, an excitation signal is output to the output line 12B of the blower fan 7, the control relay 18 is operated, and the relay contact 18b is closed, whereby the blower fan 7 is operated with a delay.

If the judgment 54 is NO and the time has not passed for 5 minutes, the control flow returns to the beginning of the control flow, and the LED is turned on (process 51) → the ceramic heater is turned on (process 52) → elapsed time integration (process 53). → Each operation of the judgment of elapse of 5 minutes (judgment 54) is repeatedly executed.

In this way, even if the coil heater 6 is disconnected, if the ceramic heater 5 is ok, the delay control is performed such that the fan 7 is operated after the ceramic heater 5 has sufficiently generated heat. Accordingly, the user can comfortably perform treatment using infrared light without using the infrared treatment device 1 without feeling cold.

Next, control in the case where the ceramic heater disconnection detection circuit 20 detects that the ceramic heater 5 is disconnected but the coil heater 6 is not disconnected will be described.

In this case, even if hot air is supplied by the heat of the coil heater 6, no infrared radiation is emitted from the ceramic heater 5 and the original infrared therapy cannot be received. There is no point in treating it because it cannot be done. Therefore, in this case, if YES is determined in the judgment 42,
The power supply 16 is shut off, the coil heater 6 and the ceramic heater 5 are de-energized, and the blower fan 7 is stopped.
1). Then, this time, lighting control such as blinking of the LED 36 of the disconnection notifying means is performed to notify the user of the disconnection of the ceramic heater 5 (process 62).

As described above, by making the LED 36 blink, a lighting display (blinking display) in a form different from the above-described continuous lighting of the LED 36 that indicates that the coil heater 6 is disconnected is provided. By sharing the LED 36, the user can be notified that the ceramic heater 5 is disconnected.

Accordingly, when the power switch 10 is operated and the LED 36 flashes when the user tries to use or when the LED 36 is being used, the user sees this and stops the treatment, so that the useless use is not continued any more. can do.

The operation of the control circuit in this case is also shown in FIG.
In the circuit diagram of FIG. 5, a 5 V potential signal from the ceramic heater disconnection notification circuit 20 is supplied to the microcomputer 15 by a signal line 25.
As a result, the microcomputer 15 determines that the ceramic heater 5 is disconnected and outputs a blinking control signal to the LED display control line 37 to blink the LED 36 (continuous lighting). Excitation signals are not output to all output lines 12C, 12A, 12B of the heater 5, the coil heater 6, and the blower fan 7, so that all the control relays 19, 17, 18 are deactivated and their respective relay contacts 19b , 17b, and 18b, the energization of the ceramic heater 5 and the coil heater 6 is forcibly cut off, and the blower fan 7 is stopped.

It is needless to say that the various controls described above can be applied to a device in which the hand-type infrared therapy device 1 is set on the stand 70 as shown in FIGS. This object can be fixed by inserting the grip portion 3 of the infrared therapy device 1 into the insertion groove 71 of the stand 70. Also, the insertion groove 7
1 has slits 72a, 72b for releasing the power cord 9 of the infrared therapy device 1 inserted from above.
Are provided at different depths before and after. Then, the infrared treatment device 1 connects the power cord 9 to the deep slot groove 72.
A correct setting method is to insert the grip portion 3 into the insertion groove 71 of the stand 70 in such a direction as to be pulled out from the a.

However, the grip portion 3 of the infrared therapy device 1
Is symmetrical in cross section, the insertion groove 71 corresponding thereto is also symmetrical, so that the direction of insertion of the infrared therapy device 1 into the stand 70 may be reversed. Then, as shown in FIG. 7B, the power cord 9 is caught in the shallow slit groove 72b, and the cord is damaged,
There is a possibility of disconnection. In addition, the grip portion 3 has an insertion groove 71.
There is a problem that it is easily fixed and becomes unstable fixed.

Therefore, the cross-sectional shape of the grip portion 3 is made asymmetrical in the left-right direction. That is, as shown in FIG. 7 (a), of the four corners of the grip portion 3, the side with the power cord 9 is chamfered with a small radius (R), and the opposite side is chamfered with a large radius (R). By performing the processing, the cross-sectional shape of the grip portion 3 of the infrared therapy device 1 is made asymmetrical in the left-right direction. In accordance with this, the insertion groove 71 of the stand 70 is also formed as a left-right asymmetric groove that fits into the grip portion 3.

As a result, the direction of insertion of the infrared therapy device 1 into the stand 71 is restricted to a certain direction. Therefore, when the infrared therapy device 1 is set on the stand 71,
In this case, the power cord 9 is pulled out without being caught, and the power cord 9 is not caught or damaged in the conventional groove.

Then, a shutter-type opening area adjusting device 85 capable of reducing or increasing the opening area as described below can be attached to the outlet (irradiation port) 8A of the infrared irradiation section 2 so that Irradiation of infrared rays or warm air to a specific human body pot and treatment range from a wide range to a narrow range can be performed, so that a therapeutic effect and usability can be improved.

As shown in FIG. 8 and FIG. 9, a plurality of shutter plates 81, a ring-shaped shutter holder 82 for supporting the shutter plates 81 rotatably in conjunction with each other,
A ring-shaped cover 83 that holds the shutter holder 82 inside, and a knob 84 that is attached along the cover 83 so as to be freely movable in the circumferential direction and that rotates the shutter plate 81 in cooperation with the cover 83. The opening area adjusting device 85 is configured to adjust the opening area of the central space portion 88.

In the opening area adjusting device 85, a plurality of hook-shaped mounting projections 86 provided at appropriate intervals on the inner peripheral edge of the rear end of the ring-shaped cover 83 are the outer shell of the infrared irradiation section 2. By fitting into an engaging recess 87 formed on the outer peripheral surface of the cylindrical case 4, it can be detachably attached to the outlet (irradiation port) 8A of the infrared irradiation section 2 of the infrared treatment device 1. I have. Reference numeral 89 denotes a ventilation net for preventing dust and the like from entering the main body.

Therefore, when the knob 84 is rotated in a certain direction, for example, counterclockwise in the attached shutter-type opening area adjusting device 85, FIG.
As shown in (2), the plurality of shutter plates 81 extend to the center while rotating in conjunction with each other to reduce the opening area of the central space portion 88. On the other hand, if the knob 84 is rotated in the counterclockwise direction, the plurality of shutter plates 81 rotate and retreat in conjunction with each other, so that the opening area of the central space 88 is widened. Works the same as.

Therefore, when the central space portion 88 is narrowed, the infrared rays to be irradiated are narrowed down in a beam shape as shown in FIG. It becomes possible. If the infrared beam is thinner, it will have a moxibustion effect. Also, FIG.
If the central space 88 is expanded as shown in FIG. Due to the opening area of the shutter-type opening area adjusting device 85 that is narrowed or widened in this manner, the air flow rate is changed as indicated by large arrows and small arrows shown in FIGS. 8A and 8B, respectively. In addition, since the air blowing range can be changed and the infrared irradiation range can be freely changed, the treatment range can be freely changed and the treatment can be performed efficiently.

[0064]

As described above, the infrared therapy apparatus has a coil heater which plays a role of letting out a hot air instead of a cold wind at the beginning of treatment by a blower fan in the infrared irradiation part, and generates heat after the coil heater. The structure is equipped with a ceramic heater that emits infrared light, and if these heaters are disconnected, the treatment function will be affected. In this case, the treatment function is not completely disabled, but the treatment function is limited to some extent. However, it is desirable to be able to continue treatment in a suboptimal manner of use.

Therefore, in the first invention of the present invention, first, a disconnection detecting circuit for the coil heater is provided, and when the disconnection of the coil heater is detected by the detecting circuit, the operation of the blower fan is stopped. As a result, when the blower fan is driven even when the coil heater is disconnected, a cold wind is generated, and thus a problem such as a feeling that the wind is cold immediately after the start of the operation is prevented. Disappears.

Further, according to the second aspect of the present invention, even if the coil heater is disconnected, infrared treatment can be performed if the ceramic heater is not disconnected. Since it was controlled to operate the blower fan that was stopped later, the blower fan operates with the ceramic heater generating heat.
The user does not feel the cold of the wind, and the warm air is generated, so that the user feels comfortable and the feeling of use is greatly improved.

Further, according to the third aspect of the present invention, the disconnection of the coil heater is reported by the reporting means, so that the user can be notified of the fact. The user knows this and can immediately take necessary measures such as repair.

In the fourth invention of the present invention, a disconnection detection circuit for the ceramic heater is also provided, and when the detection circuit detects disconnection of the ceramic heater, the operation of the main body is stopped. The user can know that the treatment is being performed, and even if the coil heater that has not been cut off is energized, the infrared treatment with the original ceramic heater cannot be performed, so that treatment with little effect using only the coil heater can be continued. Can be lost.

Further, according to the fifth aspect of the present invention, when the disconnection of the ceramic heater is detected, the notification means is notified by a method different from that when the coil heater is disconnected, so that it is used without being confused with other abnormalities. Can be notified. In addition, cost can be reduced by sharing the notification means.
