FIG. 4 is an enlarged view of the control board (8) shown above (111).
, is an operation knob for the power switch a, and (112) is a room temperature adjustment knob for changing the resistance value of the variable resistor. This is an operating knob that controls opening and closing of the preheating switch and timer switch.

The present invention has the above-mentioned configuration, and below, the operation to bring the temperature inside the sauna room to a temperature suitable for bathing will be explained in degrees Celsius. As shown in FIG. Although not shown, the power lamp aO lights up. Then, when the operation knob is set to the preheating position (B), the preheating switch cover is closed. By closing the preheating switch (2), the DC power supply VDD (
Hereinafter referred to as the power supply Vゎ), the resistor υ, buffer (c),
It is input to the input side of the NOT element ση via a diode, a resistor σ9, and a notch σe, and the power of the NOT element is fixed at a low level.

On the other hand, the divided potential of the power supply ■Dtl by the resistor (c) and the room thermistor is input to the inverting input terminal 01) of the second comparator (to), and the resistor (to) and the non-inverting input terminal 03 are input. The divided potential of the power supply vD by the combined resistance value of the variable resistor (product) and the resistor (c) is input. The resistance value of the room thermistor (c) decreases as the temperature rises, and when the preheating switch is closed, the temperature inside the sauna room is low, so the resistance value of the room thermistor (c) decreases as the temperature rises.
has a large internal resistance value, and a high-level potential is input to the inverting input terminal 01). Therefore, the second comparator (
) outputs a level of no, which is the level of resistor c.
It is input to the NOT element (to) via Iη. Therefore, since the NOT element (to) outputs a low level, the first transistor is made non-conductive, so the circulation of hot water is not stopped by the excitation of the first relay a.

Also, from the time the power switch is turned on (closed), the oscillation circuit (
G) starts to oscillate, but the divided potential (high level) of the power supply vtli by the resistor 6a and the resistor (110) is input to the input side of the NOT element I3, so the output of the NOT element I3 is fixed at a low level. Therefore, the NC) T element (1 m) connected via the diode 1 m and the resistor
The input side of o5) is also fixed at low level. Therefore, the NOT element (105) continues to output high level. Therefore, the oscillation from the oscillation circuit is combined with the high level output from the NOT element (105) via the diode (104) as described above at the connection point via the resistor (T).
Since the input is continuously made to the base of the fourth transistor through the resistor, the fourth transistor becomes conductive and the power supply voltage is connected to the ground through the resistor. Since it is energized, the buzzer (E) will not generate an alarm sound.

Furthermore, the first comparator (two non-inverting input terminals (to) K is the resistance θ4), inputs the applied voltage 1 of the beginning V7 due to the 1-mass resistance, and the inverting input terminal (B) is a power supply (2) made up of a resistor (c) and a room thermistor (2), which is input to the inverting input terminal (01) of the second comparator C3+1. . The divided potential of the comparator Q21 is input, but since the resistance value of the room thermistor wire is large as mentioned above, the sum and the comparator Q21
Although the output of is low level, it is converted to high level by the NOT element 6I and is connected to the connection point (to) the input side of the NOT element I2 mentioned above via the resistor and capacitor f111. It has no effect on the line.

When the temperature inside the sauna room rises, the internal resistance value of the room thermistor (c) decreases, and the voltage level at the inverting input terminal (5) of the first comparator (2) increases. ), and the output of the converter is inverted to output a high level, which is inverted by the NOT element and converted to a low level. Therefore, the high level at the connection point (to) is drawn in for a predetermined period of time via a differentiating circuit made up of a resistor and a capacitor 16υ (in other words, when the potential at one end of the capacitor Ill falls, the potential at the other end is drawn in only by the amount outside of the fall). (The charging time is determined by the resistance and the capacitance of the capacitor 6D.) Therefore, the potential on the input side of the NOT element 1a remains at a low level for the charging time (predetermined time) of the capacitor 6D. , the NOT element f13 outputs the /S level for a predetermined period of time. In addition, the output high level charges the capacitor (106) via the first diode and the resistor, and the capacitor (106)
The current from the time when charging is completed is energized to ground via the diode (107) and resistor (109).

Therefore, on the input side of the NOT element (105), the noise level remains unchanged for a predetermined time (the discharge time of the capacitor (105)) due to the discharge of the charge in the capacitor (106). During the predetermined period of time, the output of the NOT element (105) is at a low level. Therefore, the oscillation voltage output from the oscillation circuit is intermittently passed through the resistor (T) to the fourth transistor (T).
When the cough transistor (goods) is non-conducting, the power supply vI, I, and the resistor (
9al@(tot) is input to the base of "'(g5+7))" sister (2), and the conduction of the transistor (2) causes the power supply V0 to conduct through the resistor ((g5+7)) (102). The buzzer (E) generates an alarm sound due to the potential difference generated between one input side (95a) and the other input side (95b) and the ground side (95c) of the buzzer (E). The buzzer (951) generates an intermittent sound by switching (2).

As mentioned above, when the temperature in the sauna room reaches the reference set temperature, the buzzer (g) generates an intermittent sound for a predetermined period of time to notify the user that it is possible to take a bath.

Next, the operation knob is set as shown in Fig. 6 (when the user sets it to "1" at any time, for example, the timer switch side is opened for 10 minutes. When the operation is turned on ((j), the preheating switch (■) is opened and the timer switch (66) is pressed.
) is closed, so the electric current * v due to resistance − and resistance −
, , is input to the base of the third transistor 631 via the buffer σ[, and the divided potential of the transistor ff3
conducts to excite the first relay α. Therefore, the first relay switch (13a) is closed and the timer motor Q2
A power supply (9) is applied to J.

In addition, the non-inverting input terminal C13 of the second comparator (to) is connected to a variable resistor (b) whose resistance value changes depending on the rotation of the temperature control knob (112), and a combined resistance value of the resistor c39. The divided potential of the power supply voD by (to) is input. Furthermore, as mentioned above, when the temperature inside the sauna room reaches the temperature set by the user, a low level is input to the inverting input terminal 6Il due to a decrease in the resistance value of the room thermistor (c). Output.

Therefore, the NOT element (
) outputs −・Irepel, and the high level is connected to resistor 09.
The first transistor (410 conducts 4G, so the third relay 07) is energized, and the third relay switch (17a
) is closed and the solenoid valve ←) is energized so that it is at a high temperature supplied from a heating source (not shown). Stops the circulation of water and prevents the indoor temperature from rising. Furthermore, when the temperature inside the sauna room decreases by stopping the circulation of the hot water supplied from the heating source, the internal resistance value of room thermistor 4 increases, causing the second comparator (to) to become non-inverting. The voltage level at the inverting side input terminal C31) rises higher than that at the input terminal 6, and the output of the comparator (to) becomes a high level, which is converted to a low level by the NOT converter via the resistor 0D. Therefore, the first transistor (4G) connected via the resistor T3I becomes non-conducting, demagnetizing the third relay αη, and the third relay switch (17a) is opened, causing a connection to the solenoid valve V4-. The temperature in the sauna room is raised by stopping the electricity supply and thus circulating hot water supplied from a heating source (not shown).

Therefore, the variable resistor (goods) is connected to the temperature control knob (112).
) The temperature desired by the user can be maintained by repeating the above-mentioned operation by setting the temperature arbitrarily by rotating the temperature.

Also, turn on the timer switch (bath time setting)
The divided potential of the power supply VnD by the resistor 691 is applied to the third comparator (the inverting input terminal 1461) via the buffer σO and the resistor συ fist diode 60, and the capacitor 4 is charged. , the comparator (4
A divided potential of the power supply ■□ by a resistor (43 (44)) is applied to the non-inverting input terminal (43) of D. Therefore, the comparator (41) outputs a low level, and the low level is NOT
It is converted to a high level by the element (c) and applied to the base of the second transistor (to) via the resistor 67). The transistor is therefore conductive and the second relay a9
, the second relay switch (15a) is closed and the power supply (9) is turned on to the interior light (14), turning it on.

Next, a description will be given of what happens after the set time of the timer motor Q3 has elapsed. When the user sets the bathing time and the bathing time has elapsed, the timer switch opens and the third
Since the transistor σ becomes non-conductive, the first relay 03 is demagnetized and the first relay switch (13a)
will be released. In addition, since the high level output of the NOT element ffη is input to the NOT element (to) via the diode σ, the output of the NOT element (to) is set to a low level, the transistor ml is made non-conductive, and the third relay Demagnetize αη. Therefore, the third relay switch (1
7a) is opened, and energization to the solenoid valve (4) is stopped.

Furthermore, the inverting input terminal (461) of the third comparator (41) has a voltage at the non-inverting input terminal due to the discharge of the charge in the capacitor charged by the high level input from the above-mentioned timer switch. Since the voltage level of the inverting input terminal 14119 is higher than the voltage level of the inverting input terminal 14119 for a predetermined time (the high level holding time of the capacitor (4)), the comparator (4)
1) outputs a low level, and the low level is converted to a high level going up to the NOT element, and the second transistor (
Although the capacitor (4) is conductive, the output of the third comparator (41) is inverted to high level after the capacitor (4) is discharged.Therefore, it is converted to low level by the NOT element (41) and the output of the second transistor Since the group is made non-conductive, the second relay (11) is also demagnetized and the second relay switch (15
In a), the timer switch is opened and the interior light Q4 is turned off after a predetermined time (the high level holding time of the capacitor (4)) after the timer switch is opened.

Also, when the timer switch sister opens, the potential at one end of the capacitor drops, so the potential at the other end drops.
The high level at the point is drawn in for a predetermined period of time by a differential circuit made up of 15 resistors and 6 capacitors. Therefore, N
Since the input side of the OT element 12 is kept at a low level for a predetermined period of time (the time until the charging of the capacitor (T) is completed), the high level output from the NOT element causes the input side to pass through the diode and the resistor as described above. capacitor (10
6) is charged.

Therefore, as soon as the charging of the capacitor 6 is completed, NO.
Although the output of the T element loop also becomes a low level, charging of the capacitor (106) is completed by the NO level for a predetermined time when the NOT element is used. Furthermore, the high level voltage charged in the capacitor (106) is blocked by the diode &lK even if the high level related to the NOT element is reversed to the low level, so the NOT element (105)
The output of the NOT element (105) is converted from a high level to a low level, and the buzzer (E) emits an alarm sound as described above due to the intermittent oscillation voltage output from the oscillation circuit. )'s No 1 Repel retention time 1 Upper 8 JJ-1 #Tashi ζ fk No 1 this silk ^ casting 7

Notify the user of the end of the one hour timer (bath time) by means of notification means such as
Since the indoor light <14] is turned off after a predetermined period of time from the end of the preheating period, the user can take a sauna bath with a simple operation. Because you can know this, there is no need to waste electricity, such as waiting for a considerable amount of time to take a bath, as was the case in the past. Furthermore, since the interior light I and the timer switch are linked, it is possible to prevent forgetting to turn off the interior light α, and to delay turning off the interior light α from the end of the timer time (bath time). Since it is configured to turn off,
When the user continues to take a bath (when extending the bathing time)
It is easy to use and practical because all you have to do is open the window (7) of the front door (5) and operate the operation knob (67) from inside the sauna room.

Further, although an embodiment of the sauna bath apparatus of the present invention has been described using hot water as the heating source, the present invention is not limited to this, and the heating source may be a heater that generates far infrared rays or the like. It may be a heater that only heats the room.

Further, in one embodiment of the present invention, a buzzer (E) is used as the notification means, but visual notification means such as a light emitting element such as an LED may also be used.

Furthermore, in one embodiment of the present invention, an oscillation circuit (G) is provided to intermittently generate an alarm sound by a buzzer (E), but it is possible to continuously emit an alarm sound without providing the excavation circuit (931). may be generated.

(f) Effects of the Invention The present invention is as described above, and heats the interior of the sauna by switching the start of operation to preheating, and when the temperature inside the sauna increases to the reference set temperature, the preheating is activated by the notification means.
