Description

Rotary display type water tap for lighting in response to water temperature

The present invention is a partial improvement of the present patent application (patent publication No. 10-2003-0013498), "water temperature sensitive water light emitting device". In particular, the present invention relates to a water-emitting light emitting device which has a summary that the power generation unit and the sensor unit are implemented with the same components, and the color mixing of the light emitting unit is achieved by the rotating substrate.

The applicant's published patent is to generate electricity by using the water pressure of the water discharged through the water pipe and to emit light of a different color according to the water temperature of the tap water used as a power source so that the user can visually check the temperature of the water This is to prepare for aesthetic effect and sudden change in water temperature.

Referring to FIG. 1, the disclosed patent discloses a power generation unit 10 for producing alternating current by rotating a small magnet turbine using discharge pressure of tap water, and converts the alternating current generated in the power generation unit 10 into direct current. Power supply unit 20 to supply to each component, the control unit 30 for controlling the power supply of the power supply unit 20 by detecting the opening or closing of the water pipe, and the temperature of the tap water is installed in the portion mixed with cold water and hot water Sensor unit 40 for detecting the light, the light emitting unit 50 for outputting light by varying the color according to the water temperature detected by the sensor unit 40 and the water output from the light emitting unit 50 It consists of a light transmission unit 60 to deliver to the discharge port of.

The light emitting unit 50 emits LED chips of each color according to the temperature of tap water by using two-tone LEDs (eg, blue and red), and at mid-temperature, emits two LED chips at the same time to produce mixed colors. have. However, two-tone color LEDs are not only expensive, but even when two LED chips emit light at the same time, the mixed color alone (eg blue + red = purple) does not give the user enough inspiration. In particular, when the above method is applied to the shower head, a large area of a part where the tap water is discharged is insufficient, so that only one small LED is insufficient, thereby causing a problem in that a unit price increases or a failure rate increases.

In addition, in FIG. 1, the small magnetic turbine 11 is installed in the tap water discharge port, and the coil 13 is fixed around the tap water to rotate the magnet turbine 11 by the discharge pressure of tap water to generate electricity in the coil 13. However, there is a problem that the generated power is not sufficient just to install a small turbine in the discharge port of the faucet.

In addition, although the sensor unit 40 measures a water temperature by separately installing a known temperature sensor in a faucet or measures the resistance of water by contacting the sensor electrode with water, there is a problem in that a cost of separately purchasing a temperature sensor increases. In addition, since the sensor is in direct contact with water and an electric current flows, the sensor is corroded by the electrolytic action between the water and the sensor electrode, and unnecessary gas is generated, thereby causing malfunction.

Thus, the present inventors, in order to improve the disadvantages of the disclosed patent, respectively installed a high-temperature LED and a low-temperature LED of different colors, and at mid-temperature, both LEDs emit light, but by rotating them, the color is naturally mixed. In particular, even when applied to a large water discharge part such as a shower head, only one LED can give a sufficient aesthetic sense, and an improved structure that can sufficiently increase power generation capacity by changing the structure of the power generation part is applied. The light emitting water device was developed. In addition, the sensor has been improved to devise a new structure that can measure the temperature of water without an electrode in direct contact with water.

As described above, the present invention relates to a water temperature-sensitive water light emitting device including a light emitting unit that outputs light by varying colors according to the detected water temperature by sensing the temperature of tap water, wherein water from the water light emitting device is discharged. It includes an impeller, a rotor, and an LED substrate rotatably installed with a rotation center installed at an inner center of the nozzle unit as a rotation axis.

Here, the impeller has a plurality of rotary blades to rotate by the water pressure of the water obtained, the rotor and the LED substrate is physically coupled to rotate simultaneously with the impeller, the stator is disposed around the rotor When the impeller rotates, a rotor coupled to the rotor rotates, and a power generation action is performed by interaction with a stator disposed around the rotor, and the substrate is coupled to the rotor and rotates together. At least one high-temperature and low-temperature LED is installed toward each other. By including a water temperature measuring unit for measuring the temperature of the water in accordance with the change in the time constant of the capacitance C of the water filled between the one point of the rotor and one point of the stator as the dielectric and the resistance component R due to the resistance of the water, The high temperature LED at high temperature and the low temperature LED at low temperature emit all of them.

Hereinafter, an embodiment of a rotation display type water temperature sensitive water light emitting device according to the present invention will be described.

2 shows the overall structure of the present invention. Although FIG. 2 uses the showerhead as an example, it is obvious that the same structure may be applied to the faucet. 2, in the present invention, the center of rotation 104 is installed at the center of the nozzle portion 102 through which water is discharged, and the impeller 106 and the rotor 108 and the center of rotation 104 are rotated. The LED substrate 110 is rotatably installed. The impeller 106, the rotor 108, and the LED substrate 110 are physically coupled to rotate together at the same time. However, they are not electrically coupled. The stator 112 is disposed around the rotor 108 in the form of a continuous ring or an intermittent ring. The impeller 106 has a plurality of rotary blades 107 so as to rotate at the water pressure of the water 100 obtained (see FIG. 3). When the impeller 106 rotates, the rotor 108 coupled thereto rotates, and power generation is performed by interaction with the stator 112 disposed around the rotor 108. Here, the rotor 108 may be an electromagnet and the stator 112 may be a permanent magnet, but vice versa.

The relationship between the rotor 108 and the stator 112 is shown in FIG. That is, the rotor 108 rotates in the center and the stator 112 disposed around it is stationary. In FIG. 4, the stator 112 is introduced as a continuous ring, but of course, the power generation operation may be performed even in the case of an intermittent ring. The gap 109 between the rotor 108 and the stator 112 is always filled with water (in this invention, the water temperature is measured using water between the gaps 109. This will be described later). 4 also shows an LED substrate 110. The substrate 110 is coupled to the rotor 108 and rotates together, and the substrate 110 is mounted with an LED 111 facing outward. The LED 111 need only have one for high temperature and one for low temperature. Since the substrate 110 is rotated even without using a plurality of LEDs, the entire water discharge part may emit light. In particular, by turning on both the high-temperature LED and the low-temperature LED at mid temperature and rotating them, the mixed color is displayed naturally. By changing the mounting position of the LED 111, it is also possible to change the light emission pattern of the mixed color according to the rotation.

Next, Figure 5 shows the configuration of the water temperature sensor portion improved in the present invention. In FIG. 4, it is mentioned that water is used between the rotor 108 and the stator 112. As shown in Fig. 5, the rotor 108 and the stator 112 serve as a capacitor as a whole. That is, between one point of the rotor 108 and one point of the stator 112, there is a capacitance C using water as a dielectric and a resistance component R due to the resistance of water. Since these two components change with the change in water temperature, the time constant of this RC value changes, and if the change can be read, the water temperature can be measured. That is, as shown in FIG. 5, C can be seen as a variable capacitance C _V.

5, the oscillation part 114 is comprised including this RC value. Since the oscillation frequency of the oscillator 114 is a function of the R value and the C value, the oscillation frequency will change according to the change of R or / and C, and the step of changing this frequency is tuned in the tuning circuit 116 to detect the detector ( When detecting (converting the alternating frequency into direct current) at 118), the high and low temperatures and the medium temperature are measured relatively, and each detected signal is amplified by the corresponding amplifiers 120a, b, and c. You can. By applying the configuration of FIG. 5, since the water temperature can be measured by the rotor 108 and the stator 112 which must be present in the air without contacting a separate sensor electrode in the water, the existing problem can be eliminated. .

As described above, according to the present invention, in implementing the light emitting water supply device, it is not necessary to use a two-tone color LED and generates a mixed color by rotation, thereby lowering the manufacturing cost and increasing the aesthetics. In addition, the power generation capacity can be increased by applying a large-capacity impeller, rotor, and stator, and the water temperature can be measured by using the structure of the rotor and the stator, thereby eliminating the need for a sensor having an electrode in contact with water. The cost of production can be reduced, as well as the failure rate.
