The present invention relates to a water power generation apparatus for water and a water temperature indicator having the same, more specifically, small volume, easy to install, can be used safely in the bathroom, etc., rapid corrosion due to excessive contact of the components with water In addition, the present invention relates to a water power generation apparatus capable of preventing a decrease in performance and a decrease in water pressure, as well as improving power generation performance and stably producing electric power at low water pressure, and a water temperature indicator having the same.

In general, each household receives water through the tap water and is used. A faucet connected to the tap water and discharging water is provided with a cold water pipe for supplying cold water and a hot water pipe for supplying hot water. Accordingly, the user is provided with mixed water in which cold water and hot water are properly mixed.

Here, the hot water supplied to the hot water pipe is heated and supplied through the boiler of each home or through a machine room such as an apartment in a central supply method. If the user malfunctions the water heater because the temperature is 60 ° C or more, the hot water is burned by the hot water. There is a risk of being injured.

In particular, in the early stage of hot water use, the low temperature hot water remaining inside the hot water pipe is often supplied to use the high temperature setting of the hot water. If the hot water is continuously used in this state, the high temperature corresponding to the temperature setting is maintained. As hot water is supplied suddenly, it is often unexpectedly burned.

Therefore, in recent years, the power generation device for producing electric power using the flow of water by the pressure of the water is provided so that the user can recognize the temperature of the mixed water discharged from the faucet, the user by using the power generated in the power generation device for water A water temperature indication faucet was developed to indicate the water temperature of the water discharged to the public.

Water supply water temperature display faucet including such a conventional water generator for power generation is shown in FIG.

In the conventional water temperature display faucet for water, the power generation unit 10 for producing alternating current by rotating the magnetic turbine 11 by using the discharge pressure of the tap water, each component by converting the alternating current produced in the power generation unit 10 to direct current Power supply unit 20 for supplying to the control unit 30 to detect the opening and closing of the water supply pipe to control the power supply of the power supply unit 20, the sensor unit for detecting the temperature of the tap water is installed in the portion mixed with cold water and hot water ( 40), a light transmission unit for outputting light by changing the color according to the water temperature sensed by the sensor unit 40 and a light transmission to receive the light output from the light emitting unit 50 to the discharge port of the water pipe It consists of a part 60.

There is a problem of deterioration.

In addition, the magnetic turbine 11, which acts as a rotor, performs a role of an impeller that converts the flow of water into a rotational force while including a heavy magnet, thereby increasing the size and weight of the impeller more than necessary, As the friction is increased, the power generation performance is lowered, and the relatively large and heavy impeller and the components provided in the passage through which the water passes have a disadvantage in that the water flow is interrupted and the water pressure is reduced.

In addition, when the water pressure is low, the power generation unit 10 provided in the conventional water temperature display faucet for water is stable because the large and heavy magnet turbine 11 does not rotate or rotates at a very low speed due to frictional force acting on the rotating shaft. There is a problem that cannot be produced.

On the other hand, conventional water temperature display faucet is not only very cumbersome, because all the components are distributed in each part of the faucet to install, replace and remove the entire bulky faucet in order to install, replace and dismantle. There is also an increasing disadvantage.

Before describing this, the structure of the shower installed on the wall of the bathroom will be described, as shown in Figure 10, the hot water pipe (HP) supplied with hot water and the cold water pipe (CP) supplied with cold water is mixed valve (MV) ), The mixing valve (MV) adjusts the mixing ratio of hot and cold water according to the position of the lever operated by the user to make the mixed water.

The mixed water is discharged to the discharge parts (EH-1, 2, 3) through the connecting hose (CH), so that the water generator 100 described above is connected to the connection hose (CH) to measure the temperature of the mixed water. Is installed on. In addition, the water generator 100 may be directly installed in the mixing valve (MV) so that the mixed water discharged from the mixing valve (MV) flows directly into the inlet pipe (112).

In general, the shower is provided to discharge the mixed water through the various discharge parts (EH-1, 2, 3), the user can select and operate to which discharge portion (EH-1, 2, 3) the mixed water is discharged The selector valve FV is installed in the connecting hose CH.

The second region 132b is suppressed, and the impeller 120 is installed in the first region 132a, and the power transmission unit 170 other than the impeller 120 is installed in the second region 132b. Components other than the impeller 120 may prevent sudden corrosion, deterioration and decrease in water pressure due to excessive contact with water, and one or more pieces of water may have wings of the impeller 120 through the injection slit 131-1. The power transmission unit 170 is provided to be concentrated and sprayed at 121 and has a speed increase function, thereby improving power generation performance and enabling stable power production.
