Example

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment according to the present invention. 1 to 6 show a detailed configuration diagram and a configuration diagram for each component of an embodiment of the present invention.

Referring to Figures 1 to 3a, the present embodiment uses a discharge pressure of the tap water to rotate the small magnet turbine to produce alternating current 10 and the alternating current produced in the power generation unit 10 to direct current A power supply unit 15 including a rectifying unit 20 to switch to supply to each component, the control unit 30 for controlling the power supply of the power supply unit 15 by detecting the opening or closing of the water pipe, and mixed with cold water and hot water The sensor unit 40 is installed in the portion to detect the temperature of the tap water, and the light emitting unit 50 and the light emitting unit 50 to output light by changing the color according to the water temperature detected by the sensor unit 40 It is configured to include a light transmission unit 60 for receiving the light output from the light transmission to the discharge port of the water pipe. Hereinafter, the detailed configuration and operation of each component will be described.

1) Power Supply Unit (15)

The power supply unit 15 includes a power generation unit 10 and a rectifier 20. The development principle in the power generation section 10 is Faraday's law, similar to the principle of hydropower. Faraday's law states that electricity is generated in a coil by changing the magnetic flux in the coil. In this embodiment, as shown in detail in FIG. 4A, the small magnetic turbine 11 is provided near the discharge port of the tap water, and the coil 13 is fixed around the magnet turbine 11 by the discharge pressure of the tap water. ) Is rotated to generate electricity in the coil (13). At this time, the electricity generated in the coil 13 is alternating current (AC) whose magnitude and direction change with time. 4B is a cross-sectional view taken along the line A-A of FIG. 4A. The principle of rotation of the magnet turbine 11 is similar to the principle of the pinwheel rotating in the wind. When the magnet turbine 11 is arranged at an angle with respect to the horizontal axis, the magnet turbine 11 is rotated by the pressure of the discharged water.

Generating electricity using tap water, as in this embodiment, is almost a semi-permanent power system, which can be said to be a very practical and groundbreaking method that can eliminate the risk of electric leakage when using a commercial power source for home use and the inconvenience of occasional replacement when using batteries. .

The rectifier 20 converts and stores the alternating current produced by the power generation unit 10 into direct current (DC) and supplies the same to each component. The rectifier 20 may be configured by a combination of a rectifier circuit and a power storage circuit including a capacitor, which may be freely deformed by a person skilled in the art in designing a range within the known art. In this embodiment, the power generation unit 10 is configured as a system capable of producing power in itself by using the discharge pressure of the tap water, but the same effect can be achieved by using a conventional household commercial power supply or a DC battery. Self-explanatory

2) control unit 30

The controller 30 is a component that controls the power supply from the power supply unit 15 according to opening and closing of the water supply, and as shown in FIG. 5A, the magnet valve 31, the spring 33, and the reed relay 35 are disposed. It is configured to include. Since the spring 33 is installed in the water pipe, it is preferable that the spring 33 is made of a material that does not rust, such as stainless steel or nonmetal.

The control unit 30 fixes one end of the spring 33 to the water pipe and installs a magnet valve 31 at the other end to move the magnet valve 31 back and forth in accordance with the flow of water to thereby open the reed relay 35 mounted outside the water pipe. The power supply unit 15 is controlled by turning on / off.

That is, when the water valve is open and the water is leaked, the magnetic valve 31 applies the force to the spring 33 to compress the spring 33 by advancing the spring 33, thereby turning on the reed relay 35 outside the water pipe while advancing. To supply power from the power supply unit 15 connected thereto, and when the water valve is closed to stop the outflow of water, the magnetic valve 31 returns to its original position and the power supply unit 15 is turned off by turning off the reed relay 35. To stop the power supply.

5B illustrates another embodiment of the control unit 30. Holes were formed in both sides of the hollow tube 21, and the permanent magnet 23 was fixed to the free end of the spring 27 and the spring 27 having one end fixed in the hollow tube 21. The operation is similar to that described in FIG. 5A. Since the hydraulic pressure does not work when the water pipe is not open, the spring 27 is not compressed so that the permanent magnet 23 is located in front of the hollow tube 21 to turn off the reed relay. Let's do it. When the water pipe is opened, water pressure acts to compress the spring 27 and the permanent magnet 23 moves under the hole 25 formed on both sides of the hollow tube 25 to turn on the reed relay to turn on the power supply from the power supply unit 15. At this time, the tap water flows through the water pipe through the hole 25.

3) the sensor unit 40 and the light emitting unit 50

Sensor unit 40 is a component for sensing the temperature of the water, in this embodiment was installed in the cold water and hot water is mixed. Where the sensor unit 40 is installed is not limited to the portion where the cold water and hot water are mixed in this way, the place where the temperature of the water can be measured can be installed anywhere.

The light emitting unit 50 is a component that emits light by varying colors according to the water temperature detected by the sensor unit 40 by receiving power from the power supply unit 15. In this embodiment, a two-tone color LED is used, but is not limited thereto. In the case of a two-tone color emitter, hot heat is red, cold heat is blue, and room temperature is frequently or purple. However, the color of the light emitter can be changed according to the user's preference such as yellow, green, green, yellow, etc. In this case, any method such as a digital three-color system or a two-primary color intensity method can be used.

In the present embodiment, the light emitting unit 50 is composed of two LEDs 51 and 53 which emit light of different colors, and the low temperature driving unit 55 and the high temperature unit are used to drive the two LEDs 51 and 53. A driver 57 was included. When the water temperature detected by the sensor unit 40 is lower than or equal to the predetermined temperature T1, the low temperature driving unit 55 operates to emit light from the LED 53 connected to the low temperature driving unit 55, and to the sensor unit 40. When the temperature detected by the temperature is greater than or equal to the predetermined temperature T2, the high temperature driving unit 57 operates to emit light from the LED 51 connected to the high temperature driving unit 57, and when the water temperature is between T1 and T2, the low temperature driving unit 55. ) And the high temperature driving unit 57 to operate so that both LEDs 51 and 53 emit light, so that the three colors can be emitted according to the water temperature.

FIG. 3B illustrates a specific embodiment of the sensor unit 40, the high temperature drive unit 57, the low temperature drive unit 55, and the light emitting unit 55. As shown in FIG. In FIG. 3B, the sensor unit 40 includes a common electrode k2 positioned in the center, a first electrode k1 on the left side of the common electrode k2, and a second electrode k3 on the right side. Immerse yourself in tap water and keep the rest out of the way. As shown in FIG. 3B, the immersion height of the common electrode k1 is preferably higher than that of the first electrode k2 and the second electrode k3. That is, the immersion length of the common electrode k1 is longer than that of the first electrode k1 and the second electrode k3 to prevent electrical interference between the first electrode k2 and the second electrode k3. It is preferable. In addition, as the material of the electrode, it is preferable to use carbon (carbon) or stainless steel electrodes in order to prevent oxidation and electrolytic corrosion, but in the case of a consumable sensor, a nonferrous metal may be used.

The sensor unit 40 is located where hot water and cold water are mixed in the water pipe. The power source 54 is connected to the non-immersed portion of the common electrode k2, and the first electrode k2 and the second electrode k3 are connected to the high temperature driver 57 and the low temperature driver 55, respectively. . The high temperature driver 57 is composed of a diode D1, a resistor R1, a variable resistor R3, and an npn transistor Q1, and the low temperature driver 55 is composed of a diode D2, a resistor R2, a variable resistor R4, and a pnp transistor Q2. The high temperature light emitting diode L1 is connected between the collector of the npn transistor Q1 of the high temperature driving unit 57 and the common terminal, and the low temperature light emitting diode L2 is connected between the emitter of the pnp transistor Q2 of the low temperature driving unit 55 and the common terminal.

Referring to the operation of the sensor unit 40 and the light emitting unit 50 shown in Figure 3b as follows. The present embodiment uses the principle that the electrical resistance of water varies depending on the temperature of water, and the resistance is high at high temperatures and high at low temperatures. 3C is a diagram for explaining the principle of the sensor unit 40 according to the present embodiment. When the temperature of the tap water in which a part of the common electrode k2, the first electrode k1, and the second electrode k3 are immersed is high, the electrical resistance decreases, so that the current from the power source 54 passes through the common electrode k2. It easily flows to the first electrode k1 and the second electrode k3. The current through the first electrode k1 drives the transistor Q1 through the diode D1 and the resistor R1 to operate the light emitting diode L1 to emit light. On the other hand, the current passing through the second electrode k3 enters the base of the transistor Q2 through the diode D2 and the resistor R2. Since Q2 is a pnp transistor, Q2 is not driven and thus the light emitting diode L2 is not lit. When the water temperature is low, the opposite operation is performed so that the high temperature light emitting diode L1 does not light, and the low temperature light emitting diode L2 emits light. By adjusting the variable resistors R3 and R4, the base input voltages V1 and V2 of the transistors Q1 and Q2 may be adjusted to set light emission at a desired temperature. If the water temperature is within a certain temperature range, both L1 and L2 can be set to operate. In this case, the high temperature light emitting diode L1 may be selected as red light emission, and the low temperature light emitting diode L2 may be selected as blue light emission, so that the user can visually easily sense the water temperature.

The light emitting unit 50 as described above is just one example, and the light emitting unit 50 may be configured to emit light of three or more different colors according to the intention of the designer.

4) Light Transmitter (60)

The light transmitting unit 60 is a component that serves to change the color of the water discharged by guiding the light from the light emitting unit 50 to the discharge port of the tap water. In this embodiment, in order to prevent damage due to hot water, the light emitting unit 50 is mounted outside the water pipe, and the light emitted from the light is introduced into the tap water through the light transmitting unit 60 (fiber in this embodiment). . In the present embodiment, the light transmitting unit 60 is formed of an optical fiber, but is not limited thereto. On the other hand, when the light emitting unit 50 is installed to extend to the discharge port of the tap water, the light transmitting unit 60 is an unnecessary component.
