Description

  The present invention relates to a water supply control device, and in particular, supplies power for driving predetermined functional means while a water flow is flowing by power generated by a generator provided in a water supply channel. The present invention relates to a power generation type water supply control device that can store generated power and supply power to the control means that consumes power constantly by using the stored power.

In the conventional water supply control device, the power generated by the generator provided in the water supply channel is once stored in the power storage means, and the functional means is driven by this stored power and the power is supplied to the control means. (For example, refer to Patent Document 1).
In such a case, a power loss occurs when storing the generated power, and if the stored voltage is different from the drive voltage of the functional means or the control means, it is necessary to convert the stored voltage to a predetermined voltage. As a result, there is a problem that power loss occurs in combination. Furthermore, when the functional means has a large drive power such as a motor load, the power storage means must have a corresponding power storage capacity, and the power storage means has the ability to output a large amount of power. There was a problem that had to be.

  In addition, as an example of a water supply control device that solves the above problems, a first route for supplying the power generated by the generator provided in the water supply channel to the power storage means provided for storing the power consumed by the control means; A second route for supplying to the functional means without going through the power storage means and a switch means for selectively separating the first route and the second route are provided, and the switch means is turned on / off to store power. There is also one that separates the supply of generated power to the means or the function means (for example, see Patent Document 2).

  However, in this case as well, when the supply voltage to the power storage means and the supply voltage to the functional unit are greatly different, it is necessary to convert at least one supply voltage to a predetermined voltage. The problem that occurs is not solved, and in this configuration, on / off control of the switch element is added, and the control means stops because the stored power of the power storage means is insufficient while the functional means is driven. In addition to adding voltage detection control means for the storage means, there is a need for switching control means for switching the supply of generated power from the functional means to the storage means side when this voltage drops to a predetermined value. There was a problem that the control means and the circuit were complicated.

  The present invention has been made in order to solve the above-described problem, and an object of the present invention is to store power in the power storage means for power storage consumed by the control means while supplying the generated power of the generator to the functional means. In addition, it is easy to control by obtaining the predetermined voltage required for the functional means and the predetermined voltage required for the power storage means directly from the output voltage of the generator without converting the output voltage of the generator.

The second output means supplies the function means. As a result, the generated power can be supplied simultaneously to the power storage means and the functional means connected to the first output means and the second output means, respectively, and further, the predetermined voltage and power storage required for the functional means can be supplied. By obtaining the predetermined voltage required for the means directly from the output voltage of the generator, it is possible to provide a power generation type water supply control device that is easy to control and has little power loss.

  According to a second aspect of the present invention, in the water supply control apparatus according to the first aspect, the functional means has a pair of electrodes, and is generated by the generator in a state where the electrodes are immersed in cleaning water. Electric power is passed between the pair of electrodes. Thereby, electric power can be supplied independently to the electrolyzer which is an additional function of the water supply device, and as a result, it is possible to add a sterilizing component to the wash water.

As a result, surplus power can be supplied to the power storage means according to the power consumption state in the functional means for supplying power from the second output means, so that the power of the generator can be used efficiently.

According to a fourth aspect of the present invention, in the water supply control apparatus according to the third aspect, the path is from the second rectifying unit to the functional unit, and is closer to the functional unit than the power storage switching unit. A function output ON / OFF switch that opens and closes a path from the second rectification means to the function means, and the function output ON / OFF switch opens the path from the second rectification means to the function means; The power storage switching means switches the supply destination of the output of the second rectifying means from the functional means to the power storage means.
As a result, the output to the functional means is completely turned off and the load is disconnected, so that the power of the generator can be used more efficiently. That is, the influence of the mutual inductance of the first and second coils in the generator can be eliminated.

Moreover, according to the invention of Claim 5, in the water supply control apparatus according to any one of Claims 1 to 4, the windings constituting the first coil and the second coil in the generator are: Each has a different wire diameter and number of turns.
As a result, the number of windings and the winding diameter of the first coil and the second coil are made in advance, so that the voltage and current required for each of the power storage means and the functional means can be reduced while suppressing the increase in size of the generator. It was possible to supply directly from the generator.

  According to the present invention, the loss of limited electric power obtained by the generator is small, the functional means can be driven by the generated power with a simple control means configuration, and in particular, a pair of functional means immersed in washing water. When the electrode is used, it is possible to add a sterilizing component to the washing water, and it is possible to suppress the growth of bacteria and bacteria in the washing tube.

The water supply control device 1 includes a generator 2, a power storage unit 3, a control unit 6, a function unit 4, and an electromagnetic valve 5. The control means 6 is driven by the electric power of the power storage means 3 and controls the opening and closing of the solenoid valve 5 by outputting the solenoid valve ON / OFF signal 6a. When the electromagnetic valve 5 is opened, the impeller in the generator 2 is rotated by the water flow to start power generation. The generator 2 has two outputs. The first output is connected to the power storage means 3 and the second output is connected to the functional means 4 to supply power to each.

A rotating body 26, a stainless cup-shaped member 25 disposed on the outer peripheral side of the rotating body 26, and a first coil 29a and a second coil 29b disposed further outside the cup-shaped member 25. And a cover 28 that protects the stator portion. The outer peripheral surface of the magnet 23 is magnetized with 12 poles. The first coil 29a and the second coil 29b of the stator portion are wound around the coil bobbin so as to overlap each other in the rotation axis direction, and the electromotive force of the first coil 29a is supplied as the first output from the first terminal 24a and the second coil 29b. The electromotive force is individually output from the second terminal 24b as the second output.

Here, the number of turns and the wire diameter of each of the first coil 29a and the second coil 29b are the voltages suitable for the load connected to each of them, that is, the power storage of the power storage means 3 shown in FIG. Or it is preset so that suitable electric power can be generated. With the above configuration, when the water wheel 21 is rotated by the water flow, the rotating body 26 is also rotated at the same time to cause a change in the flow of the magnetic flux, and the first coil 29a and the second coil 29b are in a direction that prevents the change in the flow. An induced voltage is generated in This induced voltage is taken out from the first terminal 24a and the second terminal 24b, and the induced voltage taken out from the first terminal 24a is converted into direct current through the rectifier circuit and stored in the power storage means 3 shown in FIG. The induced voltage taken out from the terminal 24b is supplied to the functional means 4 shown in FIG.
Note that the number of power generation outputs, that is, the number of coils may be more than two, or a combination of a plurality of power storage means and a plurality of functional means. The power supply to the functional means may be configured to be ON / OFF controlled by the control means via a switch (not shown).

  Example 1 will be described in more detail. FIG. 3 is a configuration diagram of Embodiment 1 of the present invention. The functional means mentioned above is the electrolytic cell 44 as a functional water production | generation means which produces | generates the functional water with a bactericidal effect here. This is composed of two electrodes arranged in parallel while being submerged in a water passage, and generates a sterilizing component in water by passing an electric current between the two electrodes. The control means 6 outputs the electromagnetic valve ON / OFF signal 6a to ON to open the electromagnetic valve 5, and also controls the driving of the electrolytic cell 44 with the function output ON / OFF signal 6b, so that a predetermined portion (for example, for example) When the function output is ON, functional water having a bactericidal effect can be supplied to a urinal or the like, and when the function output is OFF, general washing water that is not functional water can be supplied.

  FIG. 4 is a block diagram of Embodiment 1 of the present invention. The CPU 60 as the control means is always driven with the power stored in the power storage means 3, and similarly, the sensor 33 is driven with the power stored in the power storage means 3 constantly or at intermittent timing. When the CPU 60 inputs a detection signal 33a output when the human body is detected from the sensor 33 or when the detection is cut off, and when it is determined that the signal needs to be processed and cleaned, The electromagnetic valve ON / OFF signal 6a is turned ON to open the electromagnetic valve 5, and general cleaning water is allowed to flow through a predetermined portion. The generator 2 starts to generate power by the flow of the washing water, and the generated power is stored in the power storage unit 3 via the first rectification unit 32.

Here, the setting of the first output and the second output of the generator 2 will be described.
In the first output, the electromotive force of the first coil 29a of the generator 2 is output from the first terminal 24a, and in the second output, the electromotive force of the second coil 29b of the generator 2 is output from the second terminal 24b. However, the space for installing the generator 2 is limited, and therefore the space for arranging the stator portion 29 around which the first coil 29a and the second coil 29b are wound is also limited. In order to efficiently supply electric power to the power storage means 3 and the functional means 4 within this limited space, the second coil 29b has a winding diameter of the winding forming the coil compared to the first coil 29a. Is using a thin one, and the number of turns is increased accordingly. Specifically, the first coil 29a has a winding diameter of 0.23 mm, the number of windings is 650 times, and the second coil 29b has a winding diameter of 0.18 mm. The number of windings is 1050 times.

  FIG. 8 shows the first output and the second output of the first coil 29a and the second coil 29b. The current value to be actually supplied is 37.7 mA for the first output, 27.6 mA for the second output, and the voltage value is 5 V for the first output and 9 V for the second output. However, as shown in FIG. In the following region, the voltage obtained by converting the second output to DC by the second rectifier 41 can be made higher than the voltage obtained by converting the first output to DC by the first rectifier 32. On the other hand, in the region of 30 mA or more, the voltage obtained by converting the first output into direct current by the first rectifier 32 can be made higher than the voltage obtained by converting the second output into direct current by the second rectifier 41. As a result, since the power output from the first rectifying means 32 is supplied to the power storage means 3, a desired amount of power storage can be ensured, and the power output from the second rectifying means 32 is the function output ON / OFF switch 42 The voltage required for driving the battery and the voltage required for the electrolytic cell 44 to flow the functional water having a predetermined concentration having a sterilizing function can be ensured, and suitable for the supply destinations of the first output and the second output. It is output.

In this case, the function output ON / OFF switch 42 is off, no power is supplied to the electrolytic cell 44, and the power generated by the generator 2 is generated by the first coil 29a shown in FIG. All are output to the power storage means 3 via the first rectifying means 32 on the first output side. Next, when a predetermined time elapses, the CPU 60 outputs an ON signal to the electromagnetic valve 5 to start cleaning, and turns on the function output ON / OFF switch 42 to supply generated power to the electrolytic cell 44. Thus, it is possible to wash functional water having a sterilizing function in a predetermined part. The output of the generator 2 at this time is generated by the second coil 29b shown in FIG. 2 and supplied as driving power for the electrolytic cell 44 via the second rectifier 41 on the second output side, The first coil 29a shown in FIG. 2 is also energized and stored in the power storage means 3 via the first output side first rectification means 32. Also in this case, the stored voltage rises as shown in FIG. 5 while the storage means 3 is stored.
In the first embodiment, the cleaning timing of general cleaning water is synchronized with the sensing signal 33a, but cleaning may be performed with a trigger signal such as a switch. Also, the cleaning timing of the functional water is not a predetermined time, but may be synchronized with the sensing signal 33a or may be a trigger signal such as a switch.

  Next, Example 2 will be described. FIG. 6 shows a block diagram of Embodiment 2 of the present invention. In the second embodiment, a power storage switching unit 61 and a power storage switching signal 6d for switching the power storage switching means 61 are added from the first embodiment. The power storage switching unit 61 is configured to connect and disconnect both lines of the first rectification unit 32 and the second rectification unit 41 by a power storage switching signal 6d. The power storage switching signal 6d is controlled by the CPU 60. Both lines are connected when flowing general cleaning water, and both lines are shut off when cleaning functional water. With this configuration, when general washing water is flowed, that is, when the output of the electrolytic cell 44 is stopped by turning off the function output ON / OFF switch 42, both lines are connected by the power storage switching means 61. Can be connected to store both of the electric power supplied from both the first rectifying means 32 and the second rectifying means 41 in the power storage means 3, and the amount of power storage increases.

  FIG. 7 is a time chart of the second embodiment of the present invention. At this time, as shown in FIG. 7, the storage voltage of the storage means 3 increases relatively steeply. Next, when generating functional water, the power storage switching means 61 is turned off to block the line. When cut off, the first rectifying means 32 is connected only to the power storage means 3 side, and the second rectifying means 41 is connected only to the electrolytic cell 44 side by turning on the function output 0N / 0FF switch 42. With this configuration, when power is not supplied to the electrolytic cell 44, the generated power can be stored in the storage means 3 without waste.
