Description

  The present invention relates to a toilet system, an automatic irrigation system, a washroom system, and a power generation unit, and more specifically, a toilet system, an automatic irrigation system, which can efficiently convert the flow of water to reduce the load on the environment, The present invention relates to a toilet system and a power generation unit.

  Conventionally, a toilet system including a warm water flush toilet seat, a heated toilet seat, a footlight, etc. has been invented as an electrical equipment for improving comfort in a toilet, and has been put into practical use. Similarly, there are toilet systems equipped with toilet lighting, footlights, etc. in the toilet. In addition, an automatic irrigation system that automatically sprinkles water with a sprinkler pipe equipped with a sprinkler or the like at a set time by performing electrical control with a timer and a solenoid valve has been considered.

  As an example of a toilet system, Patent Literature 1 describes that an LED illumination lamp is provided in which a flow rate adjustment handle of a faucet is formed of a transparent or translucent member and projects light on the transparent or translucent member. Accordingly, it has been proposed that the faucet device can be provided with an unprecedented novel design, and that the willingness to purchase can be expected by installing the faucet device in a store. It is also described that a small power generation unit formed on the valve body is provided to supply power to the LED lighting.

  However, in the configuration as shown in Patent Document 1, the power generation unit is the minimum necessary so that the LED illumination lamp emits light, and the LED can be turned on in a water discharge state in which water is flowing from the faucet. However, when the water flow is stopped, the light is turned off, so there is a problem that the value of a novel design applied to the faucet is halved.

  On the other hand, since it is necessary to supply a larger amount of power in the power generation unit in order to supply electric equipment that consumes a relatively large amount of power, such as footlights, warm water flush toilet seats, heated toilet seats, and solenoid valves, It was necessary to obtain a supply of electric power (AC 100V) or to supply power stably using a dry battery. Therefore, the toilet system, automatic irrigation system, and washroom system having electrical equipment to obtain convenience and comfort have a problem that the environment is burdened by using electric power.

  The present invention has been made in consideration of the above-described matters, and the object thereof is to enable power supply to electrical equipment even in an environment where there is no power supply from a commercial power source, and does not place a burden on the environment.

Item 1).

  According to the toilet system configured as described above, when the user opens the stop cock, the water stored in the water storage tank flows vigorously, the power generation unit generates power, and the power is supplied to the electrical equipment via the control unit. The The momentum of the water released from the water storage tank is strong enough when a large amount of water remains in the tank, so that it can obtain a large amount of power. Can be stored in the power storage unit. Further, when the water stop cock is closed, the power supply from the power generation unit is lost, so that the power stored in the power storage unit can be supplied to the electrical equipment.

In addition, when the solenoid valve is closed after a lapse of a predetermined time, the power supply from the power generation unit is lost, and after that, when the current time measured by the power storage and timer becomes the set time for watering, the control unit When the water is sprayed using the water spray pipe, the power generation unit generates power using the flow of water, and the power is supplied to the timer and the control unit itself via the control unit. It is possible to keep supplying electric power to the timer using the electric power stored in the scattering part and to secure electric power for opening the solenoid valve next time.

  For example, the water spray pipe is preferably a water pipe provided with a sprinkler at the tip, but may be a water supply pipe formed with many small holes for irrigation in the side face instead of the sprinkler. The solenoid valve can be switched between water supply and water supply to the water pipe by opening and closing, and the power generation unit is configured to generate electric power by efficiently using the flow of water flowing to the water supply pipe. is there.

The electric power obtained from the momentum of the hot water discharged is sufficiently larger than the electric power required by the control unit itself, and is supplied to various electrical devices, and the surplus electric power is stored in the electric storage unit. Since the power supply from the power generation unit is lost when the electromagnetic valve is closed, it is possible to continue supplying power to the control unit using the power stored in the power storage unit, and to secure power for opening the solenoid valve. it can.

The solenoid valve can switch between supplying and stopping hot water discharged by opening and closing, and the power generation unit is configured to generate electric power by efficiently using the flow of discharged water. Since it is connected to the downstream side of the unit, electric power can be generated by the flow of hot water in which hot water and water are combined, and larger electric power can be obtained. The control unit includes a microcomputer and constitutes an electrical load having a driver circuit that generates drive power to the solenoid valve, and the power storage unit is a secondary battery or a capacitor. The electrical equipment is an electric load including, for example, lighting such as wash-lights and footlights, a microcomputer that constitutes a solenoid valve and a control unit, and the lighting minimizes energy consumption such as LEDs including organic EL.

The electric power obtained from the momentum of the hot water discharged is sufficiently larger than the electric power required by the control unit itself, and is supplied to various electrical devices, and the surplus electric power is stored in the electric storage unit. When the hot and cold water mixing tap is closed, there is no power supply from the power generation unit, so the power stored in the power storage unit is continuously supplied to the control unit to ensure power for opening the solenoid valve. Can do.

  The hot and cold water mixing tap is connected to a water supply pipe and a hot water supply pipe and mixes them at an arbitrary ratio to generate hot water and adjust the flow rate of the hot water to be discharged. Is used to generate electric power and is connected to a water supply pipe upstream of the hot water mixing unit, so that electric power is generated by the flow of water and water pressure is reduced somewhat by generating electric power.

FIG. FIG. FIG. 3 is a diagram for explaining the operation of the toilet system 1.

  A toilet system 1 shown in FIG. 1 is electrically connected to a stop cock 3 provided in a water storage tank 2 of the toilet, a power generation section 4 connected to the downstream side of the stop cock 3, and the power generation section 4.

Have.

  The toilet is, for example, a public toilet in a store or a park, for example, a toilet that does not have a commercial power source nearby for stable power supply. The water storage tank 2 is a low tank with easy maintenance that is installed at a position higher than the toilet bowl 7 and has the ability to store at least several liters of water so that sufficient momentum can be obtained. The water storage tank 2 includes an operation lever 2a that is operated when a user flows water, a ball tap 2b that is connected to a water source and accumulates a predetermined amount of water, and a water discharge port 2c that discharges water for washing hands. Note that a large electric power may be obtained by using a high tank having excellent cleaning power instead of the low tank.

  The stop cock 3 is preferably a rubber float for a low tank provided at a drain outlet of the water storage tank 2. In the present embodiment, as an example, the toilet bowl 7 is an example of a style toilet bowl. However, it goes without saying that the present invention is not limited to the example of the toilet bowl 7.

  As shown in FIG. 2, the power generation unit 4 is connected to the downstream side of the water storage tank 2 and includes a water wheel unit 4a that obtains a rotational force by receiving a water flow, and a power generation circuit 4b that generates electric power by the rotational force. Prepare. The electrical equipment 5 includes, for example, a footlight 5a including an infrared sensor, and a heating toilet seat 5b that heats the toilet seat when the infrared sensor detects a user. The power storage unit 6 is a power storage device made of a secondary battery such as a nickel metal hydride battery, and is electrically connected to the power generation unit 4 via the control unit 8.

  The control unit 8 includes an electric circuit including a microcomputer, and this constitutes an electrical load, so that it can be said to constitute a part of the electrical equipment 5. The control unit 8 includes a measurement unit 8a that measures the voltage and current generated by the power generation unit 4, an output control unit 8b that regulates and outputs the voltage required by each electrical equipment 5a and 5b, and an output control unit 8b. A power storage control unit 8c that stores surplus power by flowing the surplus current generated in the power storage unit 6, and the power storage control unit 8c requires power supply from the power generation unit 4 as a whole of the electrical equipment 5 It has a function of maintaining the necessary power supply using the power stored in the power storage unit 6 when the power is lower than the power.

  The footlight 5a includes an infrared sensor Si that detects a person entering the toilet and an LED light Led that emits light to the feet when the infrared sensor detects a person. In addition, the heating toilet seat 5b instantaneously increases the temperature of the toilet seat when the infrared sensor Si detects a person and heats the toilet seat until it leaves the seat, for example, a Peltier element and / or an electric heating section. Is provided.

  Next, operation | movement of the toilet system 1 of the said structure is demonstrated using FIG. In FIG. 3, G represents power generated by the power generation unit 4, U represents power consumed by the electrical equipment 5, and C represents power stored in the power storage unit 6. In the toilet system 1 of the present invention, for example, when the user operates the lever 2a of the water storage tank 2 to open the stop cock 3 at the time t1, the water flows into the water turbine portion 4a connected to the downstream side. Gives a rotational force to the water turbine, and the power generation circuit 4b generates a large electric power G (voltage × current) using this rotational force. The power is measured by the measurement unit 8a and compared with the power required by the output control unit 8b. When the surplus occurs, the power storage control unit 8c performs power storage. When the shortage occurs, the power storage control unit 8c Discharge.

  That is, the voltage and current generated by the power generation unit 4 are sufficiently larger than the power U used by the electrical equipment 5 when a water flow is flowing, and the remaining power C can be stored in the power storage unit 6. In this way, when the power accumulated in the power storage unit 6 using the flow of water that has flowed up to time t2 is less than the power required by the power generation unit 4 after time t2, the power storage unit 6 to the output control unit 8b via the power storage control unit 8c.

  When the user leaves the toilet, the infrared sensor Si does not recognize the human body, so the power supply to the LED light Led is stopped from the time t3, and power consumption is such that a small standby current flows thereafter. Each electric equipment 5 can be kept operating by using the electric power stored in the unit 6 little by little.

  Next, when the user enters the toilet again at time t4, the infrared sensor Si detects the human body again, so that the LED light Led is turned on again, and the output control unit 8b instantaneously raises the temperature of the toilet seat. For this purpose, a large amount of power is supplied to the heating toilet seat for a moment, and power is supplied for heat retention when the temperature reaches an appropriate temperature, so that the user can use the toilet comfortably. In addition, since the power supply to the toilet seat is larger than that of the LED light Led or the like, it can be considered that the stored power is used up. Therefore, power supply may be continued using a commercial power source or a primary battery only when no power is stored in the power storage unit 6.

  Since the power storage and discharge cycle to the power storage unit 6 is frequently repeated in places such as a station or a storeroom where it is difficult to enter and exit, it is preferable to use a capacitor with a long charge / discharge life. A secondary battery may be used to increase the storage capacity.

  In the present embodiment, the power generation unit 4, the power storage unit 6, and the control unit 8 are illustrated as separate units so that the configuration can be easily understood. However, these units may be integrally formed to form a single power generation unit.

And a power generation circuit that obtains electric power using the rotational force obtained by the water wheel.

  The control unit 28 and the timer 25 include a microcomputer and constitute an electrical load, and the power storage unit 26 is, for example, a capacitor. However, a secondary battery may be used instead of the capacitor. The control unit 28 supplies driving power to the measurement unit 28a that measures the voltage and current generated by the power generation unit 24, the output control unit 28b that regulates and outputs the voltage required by the timer 25, and the electromagnetic valve 23. A driver circuit 28c; and a power storage control unit 28d that stores surplus power by flowing surplus current generated in the output control unit 28b and the driver circuit 28c to the power storage unit 26. The power storage control unit 28d includes the power generation unit 24. Has a function of maintaining the necessary power supply using the power stored in the power storage unit 26 when the power supply from the power supply is lower than the power required by the timer 25.

  The automatic irrigation system 1 having the above configuration opens the electromagnetic valve 23 when the time measured by the timer 25 reaches the watering time, and closes the electromagnetic valve 23 when the watering time is over. Supplies power. In addition, when the plug is opened, water flows through the power generation unit 4 so that power can be generated by the water flow. The measurement unit 28a of the control unit 28 measures this power and supplies the timer 25 with necessary power. The remaining power is stored in the power storage unit 26 via the power storage control unit 28d. In addition, since the power supply from the power generation unit 24 is stopped when the electromagnetic valve 23 is closed, the power stored in the power storage unit 26 is supplied to the output control unit 28a via the power storage control unit 28d to operate the timer 25. You can continue.

  In the case of the automatic irrigation system 1, since regular watering is performed, the power storage unit 26 can perform regular power storage. Therefore, the power storage unit 26 waits for the timer 25 and the control unit 28 during a time when water is not sprayed. If electric power can be stored to such an extent that current can be supplied, the electric power in the electric storage unit 26 will not be depleted, but power can be supplied from the battery 29 when the electric power is completely discharged.

  Since the automatic irrigation system 1 does not require any power source and can perform automatic irrigation, it can be a complete maintenance-free system and can be attached to any part regardless of the presence or absence of the power source.
