The cold water or hot water in the cold water or hot water tank is controlled to be diluted by the rotation of the stirring fan 83 '.

The AC / DC converter 1 inputs an alternating current applied from a power source and converts it into a direct current, and includes a bridge rectifier circuit composed of rectifying diodes D3, D4, D5, and D6: Diode. do.

In the bridge rectifier circuit, a cathode portion of the diode D3 and the diode D5 is configured as a + portion of a direct current, and is connected to the voltage regulator 10, and an anode of the diode D4 and the diode D6 is connected. Part is composed of-part of DC current and is connected to ground (GND) line.

The AC / DC converter 1 converts 220V alternating current (AC) current supplied from a power source into 24V direct current (DC) current by using a bridge diode.

In addition, the DC 24V current rectified by the diode rectifying circuit of the AC / DC converter 1 is applied to the UV lamp driver 50 and the device driver 60 so that the UV lamp 90 and the solenoid valve 81 are applied. In addition, it is used as a voltage for operating the pump 82 and the motor 83 to turn on the UV lamp 90 and to operate the stirring fan 83 'in the cooling tank.

Even if the supply current supplied to the AC / DC converter 1 is a direct current or an alternating current, the current output by the bridge diode outputs a direct current, even if the polarity of the direct current inputted by the user's carelessness is reversed. The current output via the bridge diode is direct current.

The voltage control unit 10 is connected to the + part of the direct current output from the AC / DC converter (1) to reduce the voltage of the direct current converted and output from the AC / DC converter (1) AC / DC conversion A constant voltage IC (Regulator IC: U4) and a constant voltage IC (Regulator IC: U3) are configured in series with the DC + part of the bridge rectifier circuit of the unit (1) to control the DC current under reduced pressure control. Is applied to (40).

The constant voltage IC U4 and the constant voltage IC U3 output a constant voltage irrespective of the input voltage, that is, receive a + voltage and output a lower voltage than the input voltage, so that the constant voltage IC U4 and the constant voltage IC ( U3) reduces the DC 24V current output from the bridge rectifier circuit of the AC / DC converter 1 to 5V.

The constant voltage IC U4 outputs a constant voltage obtained by decompressing the DC 24V current output from the AC / DC converter 1 to DC 12V, and the constant voltage IC U3 is decompressed and output from the constant voltage IC U4. Output the constant voltage which reduced the current to DC 5V.

The constant voltage IC (U4) uses a constant voltage IC of the 78L12 product and a constant voltage IC of the 78L05 product of the constant voltage IC (U3), and the voltage control unit 10 connects two constant voltage ICs of 78L12 and 78L05.

The constant voltage IC U4 and the constant voltage IC U3 have three terminals of IN, GND, and OUT, each having an input terminal and an output terminal having a common ground (GND) line, and a 78L12 constant voltage IC (U3) has 15 V. Above, the 78L05 constant voltage IC (U4) is normally operated when an input voltage of 8V or more is applied.

When the 78L12 constant voltage IC (U3) and 78L05 constant voltage IC (U4) are connected to each other, the quiescent current (current flowing through the three-terminal constant voltage IC under no load) can be reduced to about 2 mA, and the maximum output current is about 0.1 A, which leads to a low consumption current. There is an advantage that can reduce the current consumption.

The voltage regulator 10 includes a variable capacitor C1 configured between the AC / DC converter 1 and the constant voltage IC U4 and connected in parallel to a + part and a ground (GND) line of direct current. It is composed.

The variable capacitor C1 continues to accumulate at the + part of the direct current while the 24 V direct current output from the voltage regulator 10 decreases while reducing the power impedance of the constant voltage IC U4 input terminal, and the stop current increases to about 30 V. Therefore, it absorbs the transient voltage to supply a safe current of 24V to the constant voltage IC (U4).

The capacitor BC2 absorbs noise generated from the constant voltage IC U4 and the constant voltage IC U3, and the 12V DC output from the constant voltage IC U4 after being decompressed is relatively stable in voltage, thus requiring no down resistance. Therefore, use a capacitor.

The electrolytic capacitor (C3) is configured for improving the transient characteristics and high-frequency bypass, the electrolytic capacitor (C3) is configured in parallel on the output side of the constant voltage IC (U3) bridge rectification circuit of the AC / DC converter (1) It removes the ripple that appears when rectifying 220V AC of 220V and absorbs the low voltage, stabilizes the voltage to a constant voltage, and causes high frequency oscillation when the drive signal output unit 30 and the time delay unit 70 are turned on and off. Reduce malfunctions caused by malfunctions and circuit instability.

 220V AC supplied to the AC / DC converter 1 is rectified through a bridge rectifier circuit to make a direct current ripple that does not become a direct current and a part of the AC signal remains in the DC voltage (pulse flow) The capacitor is used to remove the power, but 60Hz is very low frequency, so the electrolytic capacitor (C3) is used to suppress 60Hz and its harmonics.

 The resistor R8 causes only the current of the input voltage of the constant voltage IC U4 to conduct even when the stop current of the 24V DC current output from the voltage regulator 10 rises to about 30V, thereby providing a safe current to the constant voltage IC U4. Supply.

Briefly describing the operation of the voltage regulator 10, when the DC 24V current output from the AC / DC converter is input to the voltage regulator 10 passes through the capacitor (C1), smooth, smooth DC 24V current Is provided to the primary coil of the constant voltage IC U4 through the resistor R8 so that an induced current is generated in the secondary coil of the constant voltage IC U4.

The DC 24V current input to the constant voltage IC U3 is provided to the primary coil of the constant voltage IC U3, and an induced current is generated in the secondary coil of the constant voltage IC U3.

At this time, when the switch of the constant voltage IC (U3) is turned off, the induced current induced in the secondary coil of the constant voltage IC (U3) is accumulated in the capacitor (C3) and when the accumulated DC 5V current is fully charged, the capacitor (C3) The discharged current is discharged from the DC 5V current is provided to the drive signal output unit 30, the control unit 40 and the time delay unit 70.

 The flow rate detecting unit 20 includes a sensor body 21, a slider 22, a magnet 23, and a hall sensor 24, and is configured in an outflow pipe of drinking water so that the slider 22 is sensored by the outflow of drinking water. The hall sensor 24 detects the magnetic force of the magnet 23 by sliding in the body 21 to detect the flow of drinking water and outputs a signal to the driving signal output unit 30.

The sensor body 21 is configured in a cylindrical shape and is connected directly to the outflow pipe and has a pair of guides 25 spaced apart in a predetermined width projecting in the longitudinal direction on the inner circumferential surface so as to protrude to face the inner circumferential surface of the cylinder.

The slider 22 has a columnar shape, a pin-shaped wing 26 inserted between a pair of guides 25 and protruding integrally in the longitudinal direction on the circumferential outer circumferential surface thereof, and having a magnet 23. Is mounted inside the upper portion of the slider 22, and the hall sensor 24 is configured on the upper inner surface of the sensor body 21.

If there is no outflow water of the drinking water in the state in which the flow rate detecting unit 20 is configured in the outflow pipe of the drinking water, the slider 22 is located at the inner bottom of the sensor body 21 and the drinking water is leaked, that is, the user opens the drinking cock. When the drinking water is discharged from the drinking coke, the outflow water is discharged from the inside of the outflow pipe.

As the outflow water flows from the lower portion of the flow rate detecting portion 20 to the upper portion, the slider 22 and the sensor body 21 slide upward from the lower portion of the inner surface by hydraulic pressure.

In the state in which the blade 26 integrally formed with the slider 22 is inserted into the pair of guides 25 of the sensor body 21, the blades 26 are slid and raised by the guide of the guides 25 and the sliders 22 are raised. The sensor body 21 reaches the upper portion of the inner surface.

At this time, when the magnet 23 formed on the upper inner surface of the slider 22 and the Hall sensor 24 formed on the upper inner surface of the sensor body 21 coincide with each other, the hall sensor 24 detects the magnetic force of the magnet 23. The detected magnetic force generates a clock and outputs a driving signal to the driving signal output unit 30.

The guide 25 may be configured to face each other at 180 ° intervals from the inner circumferential surface of the cylindrical, or may be composed of three of 120 ° intervals, and may be configured in a number more than that, but the larger the quantity of the guide 25 the slider 22 Since a lot of resistance is generated in the action of the two to three guides 25 are preferable.

The DC 5V current applied from the voltage adjusting unit 10 is applied to the flow rate detecting unit 20 but is not energized, and the Hall sensor 24 of the flow rate detecting unit 20 receives the magnetic force of the magnet 23. In other words, when the effluent is sensed and the clock signal is output to the driving signal output unit 30, the transistor Q4 of the driving signal output unit 30 is turned on so that the current applied from the voltage adjusting unit 10 is applied to the control unit 40. A low voltage of 5V is input to the pin 7 and the control unit 40 is a UV lamp 90 and a solenoid valve 81 to the UV lamp driver 50 and the device driver 60 according to a program embedded in the controller 40. ), A control signal capable of driving the pump 82 and the motor 83 is generated.

The driving signal output unit 30 receives the signal output from the flow rate detecting unit 20 and the transistor Q4 is turned on to output the driving signal to the control unit 40, and to the DC current of the voltage adjusting unit 10. Is driven.

The driving signal output unit 30 includes a capacitor BC3 connected to the + part and the ground GND line of the flow rate sensing unit 20, and a resistor R5 configured in the + part of the capacitor BC3 in front of the capacitor BC3. ), A resistor R2 configured in front of the resistor R5 and connected to a + portion of the voltage adjusting unit 10 and a + portion of the flow rate detecting unit 20, and configured in front of the resistor R2 and having a voltage. Transistor Q4 connected with the + part of the adjusting unit 10 to the emitter and the + part of the flow rate sensing unit 20 to the base, and the collector and ground GND of the transistor Q4. A resistor R11 connected to the line and a resistor R10 connected between the collector of the transistor Q4 and the resistor R11 and connected to the controller 40 are provided.

In the transistor Q4, the total current flows in the emitter, the base controls the flow, and the amplified signal flows in the collector.

When the transistor Q4 does not have a detection signal from the flow rate detecting unit 20, that is, there is no power clock, the emitter and the base have the same potential of DC 5V, so that no current flows. As a clock signal, current flows from the emitter to the collector by the forward power between the base and the emitter, and the current flowing through the collector is amplified compared to the current flowing to the base, and the small signal of the base is amplified and outputted to the collector. It acts as a switch or gate for amplification and signal.

The resistor R2 of the driving signal output unit 30 is mainly used when the transistor Q4 is switched (ON, OFF), and the collector has no sense signal in the flow velocity detecting unit 20 (Open). There may be a slight leakage current, which prevents the transistor Q4 from being switched by this leakage current, so that the transistor Q4 is surely turned off, and when the base is opened, external noise influences. In order to get less, it also reduces the sensitivity somewhat.

The transistor Q4 of the driving signal output unit 30 is turned on when the base voltage is 0.65V lower than the emitter voltage, so that the resistor R5 lowers the voltage of the base. The capacitor BC3 of 30 absorbs the surge voltage generated when the transistor Q4 is switched (ON, OFF), and the resistor R11 of the drive signal output unit 30 is amplified by an overcurrent more than necessary to the collector. In this case, the amplified overcurrent is passed through to bypass to protect the circuit against overcurrent.

The time delay unit 70 outputs a delay signal for delaying the driving stop signal to a predetermined time when the driving stop signal of the driving signal output unit 30 is input by stopping the flow of drinking water and the voltage adjusting unit 10. Driven by a direct current.

The time delay unit 70 includes a resistor R3 connected to the DC current of the voltage adjusting unit 10, and a jumper J1 connected to the resistor R3 and connected to the ground GND line. The controller 40 is connected between the resistor R3 and the jumper J1.

The jumper J1 is a short circuit (Turn Off) when the outflow water is detected in the flow rate detection unit 20 to conduct current to the control unit 40, the resistor (R3) and the resistor (R9) is pull-up resistor (Pull-) up Resistor) is configured at the output terminal and the power supply terminal to increase the output, i.e., to maintain a high level state.

If the outflow water does not flow in the flow rate detection unit 20, that is, when there is no clock signal of the flow rate detection unit 20, the contact is connected to the low level state and is applied from the voltage adjusting unit 10. When the DC 5V current flows out to the ground through the jumper J1, and the outflow water flows from the flow rate detecting unit 20, that is, when the clock signal of the flow rate detecting unit 20 is present, the contact short-circuit is at a high level. OFF) and a DC 5V current applied from the voltage adjusting unit 10 is directly applied to the control unit 40 so that the control unit 40 outputs a control signal to the UV lamp driving unit 50 and the device driving unit 60.

8 is a clock state in which the hall sensor 24 senses the magnet 23, and (B) is delayed even after the clock signal is stopped. When the effluent flows as a clock state (t), the jumper J1 is short-circuited to output a control signal from the control unit 40 to the UV lamp driver 50 and the device driver 60 so that the UV lamp 93 is turned on. The stirring fan 83 'is driven, and the flow of the effluent stops and the jumper J1 becomes a contact. The UV lamp driver 50 and the device driver 60 are controlled by the controller 40 for 5 minutes and 30 seconds from the stop of the effluent. The control signal is outputted, i.e., the stop clocks of the UV lamp driver 50 and the device driver 60 are delayed (t) so that the UV lamp 93 is turned on for 5 minutes and 30 seconds after the flow of the effluent is stopped and the stirring fan 83 ') Is driven.

In addition, the time delay unit 70 includes a resistor R9 connected to the DC current of the voltage adjusting unit 10 and a jumper J3 connected to the resistor R9 and connected to the ground GND line. And a controller 40 is connected between the resistor R9 and the jumper J3.

The jumper J3 is a low level state when the effluent does not flow, that is, when there is no clock signal of the flow rate detecting unit 20, the contact is connected (ON) and applied from the voltage adjusting unit 10 to 5V. When the current flows out to the ground through the jumper J1 and the jumper J3 is shorted as necessary, the DC 5V current applied from the voltage adjusting unit 10 is conducted to the control unit 40 to the UV lamp driving unit 50. The current is applied to delay the extinguishing of the UV lamp 93 of the UV lamp unit 90 for another 5 minutes and 30 seconds so that the total lighting time of the UV lamp 93 becomes 11 minutes.

The control unit 40 receives the signals output from the driving signal output unit 30 and the time delay unit 70 and the UV lamp driving unit 50 and the device driving unit 60 by the DC current of the voltage adjusting unit 10. The driving signal is outputted and driven by the DC current of the voltage adjusting unit 10.

The control unit 40 has a capacitor BC1 configured between the currents applied by the voltage adjusting unit 10, and the capacitor BC1 switches (ON, OFF) the transistor Q4 of the driving signal output unit 30. The surge voltage generated at the time and the surge voltage generated at the time of the short circuit of the jumper J1 and the jumper J3 of the time delay unit 70 are absorbed.

The UV lamp driving unit 50 applies a DC current of the AC / DC converter 1 to the UV lamp unit 90, receives a driving signal output from the controller 40, and conducts a transistor Q1 to conduct a relay. (RLY1) is turned on to turn on the UV lamp 90, and is driven by a DC 24V current applied from the AC / DC converter 1.

The UV lamp driving unit 50 includes a resistor R1 connected to the output line of the controller 40, a base connected to the resistor R1, and a collector connected to the + of the AC / DC converter 1.

And a relay RLY1 connected between the + part of the voltage regulating part 10 and the diode D1 and the − part connected between the diode D1 and the collector of the transistor Q1.

The relay RLY1 uses a PDT relay (Single Pole Double Throw Rly) having two output signals as one input signal.

The UV lamp 93 receives a driving signal output from the control unit 40 and the relay is switched by the conduction of the transistor Q1 so that the DC current of the AC / DC converter 1 is applied to the UV lamp unit 90. Is turned on, and the diode D1 absorbs back electromotive force generated when the coil current of the relay RLY1 is turned off.

In the UV lamp driving unit 50, the transistor Q1 is switched on and a current flows in the relay RLY1 coil to turn on the relay RLY1. The relay RLY1 is an inductance load and a coil current. When the OFF (OFF) of the high voltage back electromotive force is generated by using the diode (D1) to absorb the back electromotive force.

The DC 24V current applied by the AC / DC converter 1 is applied to the UV lamp driver 50 but is not energized. When the clock signal is output from the controller 40 to the UV lamp driver 50, the UV lamp driver 50 receives UV. The transistor Q1 of the lamp driver 50 is turned on so that the current applied from the C / DC converter 1 is conducted to the coil of the relay, so that the relay RLY1 is turned on and the AC / DC converter 1 is turned on. The DC 24V current applied by is input to the UV lamp unit 90 through the relay RLY1, the UV lamp 93 is turned on, and the effluent is sterilized by irradiation of the UV lamp 93.

In the transistor Q1, the total current flows in the emitter, the base controls the flow, and the amplified signal flows in the collector.

When the transistor Q1 has no clock signal from the controller 40, the emitter and the base are at the same potential of DC 24V, and thus the current does not flow. However, the transistor Q1 is forwarded between the base and the emitter as the clock signal of the controller 40. The electric current flows from the emitter to the collector by the power supply, and the current flowing to the collector is amplified compared to the current flowing to the base, and the small signal of the base is amplified and output from the collector so that the base is a switch or gate for amplification and signal. Act as.

The transistor Q4 of the driving signal output unit 30 is turned on when the base voltage is 0.65V lower than the emitter voltage, but the transistor Q1 is applied by the collector to the AC / DC converter 1. Since DC 24V is applied and DC 5V output from the control unit 40 is applied to the base, and the voltage width is large, the resistor R1 is used to lower the voltage width.

The resistor R1 is a pull-up resistor that causes the transistor Q1 to be recognized as a voltage capable of turning on the transistor Q1 even when the output voltage is low in the controller 40 so that the transistor Q4 is operated.

The device driver 60 receives the drive signal output from the controller 40 and applies the DC current of the AC / DC converter 1 to the motor 83 of the stirring fan 83 ', and the like. It is driven by the DC 24V current applied from the converter 1.

A transistor Q2 connected to an emitter connected to a ground GND line, a diode D2 connected between a + part of the AC / DC converter 1 and a collector of the transistor Q2; The + part is connected between the + part of the voltage adjusting part 10 and the diode D2, and the relay RLY2 is connected between the negative part of the diode D2 and the collector of the transistor Q2, and the relay RLY2 is connected to the direct current. A jumper J4 is provided between the power source driving device 80.

In response to the driving signal output from the controller 40, the relay RLY2 is switched by the conduction of the transistor Q2 so that a DC 24V current applied from the AC / DC converter 1 is applied to the motor 83 and stirred. The fan 83 'is driven, and the diode D2 absorbs back electromotive force generated when the coil current of the relay RLY2 is turned off.

Since the transistor Q2, the resistor R6, and the diode D2 of the device driver 60 have the same circuit configuration as the transistor Q1, the resistor R1, and the diode D1 of the UV lamp driver 50. The apparatus driving unit 60 is applied to the motor 83 to drive the stirring fan 83 'so that the cold water in the cooling tank or the hot water in the hot water tank is diluted, and the DC 24V current applied from the AC / DC converter 1 is applied. The UV lamp driving unit 50 is input to the UV lamp unit 90, the UV lamp 93 is turned on and the effluent is sterilized by irradiation of the UV lamp 903, and the device driving unit 60 is applied to the motor 83. Since the stirring fan 83 'is only rotated to dilute the cooling water in the cooling tank, the operation of each component of the device driver 60 is replaced by the description of the UV lamp driver 50.

The jumper J4 of the device driver 60 stops driving of the solenoid valve 81, the pump 82, etc. with a short off, and when the outflow water pressure in the flow rate sensing unit 20 is not normal. That is, the solenoid valve 81 and the pump 82 are unnecessary when the outflow water does not flow in the flow rate detecting unit 20 or flows out even if the outflow water flows so that the pressure in the flow rate detecting unit 20 is smaller than the set pressure. It is a configuration for saving water by preventing operation.
