Description

  The present invention relates to a faucet generator that generates electricity using the flow of running water supplied to a faucet.

  Conventionally, there has been known an automatic faucet device that senses a hand inserted under a faucet with a sensor and automatically discharges water from the faucet. There is also known a device that includes a small generator in the flow path of such an automatic water faucet device, stores electric power obtained by this generator, and supplements electric power of a circuit such as the above-described sensor.

  For example, Patent Document 1 discloses a so-called axial flow generator in which a rotating shaft of a rotating body that is rotated under the force of a water flow is substantially parallel to a direction in which the water flow flows. In Patent Document 1, a water wheel having a blade portion is provided in a flow path through which a fluid flows, and a substantially cylindrical magnet is fixed to the outer peripheral side of the blade portion of the water wheel. On the downstream side of the magnet, a coil and an inductor (yoke) for guiding the magnetic flux of the magnet to the coil are provided.

In the axial flow hydroelectric generator, the rotating body (water turbine) receives a biasing force in the downstream direction due to the water flow pressure. In addition, a force attracted toward the inductor, which is a fixed member, acts on the rotating body by a magnetic attractive force acting between the magnet and the inductor. Therefore, when the inductor is arranged downstream of the magnet as in Patent Document 1, the urging force due to the water flow pressure and the force attracted to the inductor side by the magnetic attraction force are in the same direction (downstream direction). In particular, when the magnetic force of the magnet is strong, the rotating body is strongly pressed against the bearing, and the rotational performance of the rotating body is reduced, and wear at the sliding portion between the rotating body and the bearing is promoted, resulting in durability. There is concern about the decline.

Characterized by direction Plug for the power generator is provided.

  ADVANTAGE OF THE INVENTION According to this invention, it is suppressed that an excessive force acts on the sliding part of a moving blade and a bearing, and the generator for faucets with high reliability is provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same component in each drawing.

FIG. 1 is a schematic cross-sectional view of a faucet generator 1 according to an embodiment of the present invention.
The faucet generator 1 mainly includes a cylindrical body 15, a stationary blade 21, a moving blade 25, a magnet M, a stator 50, and the like, which are accommodated in a case 12 (see FIG. 3). .

Here, before explaining the faucet generator 1, the faucet device 3 provided with the faucet generator 1 will be explained.
FIG. 2 is a schematic diagram illustrating an example of attachment of the faucet device 3.
FIG. 3 is a schematic cross-sectional view of the faucet device 3.

  The faucet device 3 is attached to the washstand 2 etc., for example. The faucet device 3 is connected to an inflow channel 5 for tap water or the like via a pipe 4. The faucet device 3 includes a cylindrical main body 3a and a water discharge portion 3b provided on an upper portion of the main body 3a and extending in a radially outward direction of the main body 3a. A water discharge port 6 is formed at the tip of the water discharge unit 3 b, and a sensor 7 is built in the vicinity of the water discharge port 6.

  In the faucet device 3, a water supply passage 10 is formed that guides the water supplied from the inflow passage 5 and flowing through the pipe 4 to the water outlet 6. A solenoid valve 8 for opening and closing the water supply flow path 10 is built in the main body 3a, and a constant flow valve 55 for limiting the amount of water discharge is built on the downstream side of the solenoid valve 8. ing. Further, a pressure reducing valve or a pressure regulating valve (not shown) for reducing the pressure when the original pressure of water supply or the like is too higher than the working pressure is built in upstream of the electromagnetic valve 8. It should be noted that the constant flow valve 55, the pressure reducing valve, and the pressure regulating valve may be appropriately provided as necessary.

  A faucet generator 1 is provided inside the water discharger 3 b downstream of the constant flow valve 55. Inside the main body 3a, a charger 56 for charging the electric power generated by the faucet generator 1 and a controller 57 for controlling the driving of the sensor 7 and the opening and closing of the electromagnetic valve 8 are provided. Since the faucet generator 1 is disposed on the downstream side of the solenoid valve 8 and the constant flow valve 55, the water supply source pressure (primary pressure) does not directly act on the faucet generator 1. Absent. Therefore, the faucet generator 1 is not required to have such a high pressure resistance, and such an arrangement is advantageous in terms of reliability and cost.

  The coil 36 (see FIG. 1) provided in the faucet generator 1 and the control unit 57 are connected via a wiring (not shown), and the output of the coil 36 is sent to the charger 56 via the control unit 57. It is like that.

  The faucet generator 1 is not limited to being provided inside the faucet fitting (the main body 3a and the water discharger 3b) of the faucet device 3. For example, you may provide in the piping (flow path) 4 which connects between the faucet | fitting metal fitting of the faucet device 3, and the water stop cock (former stopper) 105 (refer FIG. 2) provided upstream from this. .

  The faucet generator 1 is provided in a flow path between a water faucet (main plug) 105 and a water outlet 6 of the water faucet device 3 and is directed from the water faucet 105 to the water outlet 6 of the water faucet device 3. Electricity is generated by the flowing hydropower. Examples of the faucet device include kitchen faucets, living / dining faucets, shower faucets, toilet faucets, toilet faucets, and the like. In the faucet device, the discharge flow rate is set to, for example, 100 liters per minute or less, desirably 30 liters per minute or less. In particular, it is desirable that the toilet faucet is set to 5 liters per minute or less. Further, when the discharge flow rate is relatively large, such as a toilet faucet, the flow of water flowing from the water supply pipe to the generator 1 can be branched to adjust the flow rate of flow through the generator 1 to 30 liters per minute or less. desirable. This is because there is a concern that if all the water flow from the water supply pipe flows to the generator 11, the rotational speed of the rotor blade 25 increases, noise and shaft wear may increase, and even if the rotational speed increases. This is because if the rotational speed is not less than the appropriate number of revolutions, energy loss due to eddy currents and coil heat occurs, so the amount of power generation does not increase. In addition, the water supply pressure of the water pipe to which the faucet fitting is attached may be a low water pressure of about 0.05 (MPa) in Japan, for example.

  In addition, the faucet device is not limited to an automatic faucet using a human body detection sensor, but a one-touch faucet by turning on / off a manual switch, a fixed water discharge faucet that stops water by counting the flow rate, and stops when a set time has elapsed. It may be a timer faucet for watering.

  In addition, the electric power generated by the faucet generator 1 is used for, for example, light-up, generation of electrolytic functional water such as alkaline ion water and silver ion-containing water, flow rate display (metering), temperature display, voice guide, etc. May be.

  Next, returning to FIG. 1, the faucet generator 1 will be described.

Established. The cylindrical body 15 is disposed so that the central axis direction thereof is substantially parallel to the direction in which flowing water flows through the water supply passage 10 in the water discharger 3b. The cylindrical body 15 is disposed with the small diameter portion 18 facing the upstream side and the large diameter portion 16 facing the downstream side.

  Inside the cylindrical body 15, a stationary blade 21, a moving blade 25, and a bearing 34 are provided in this order from the upstream side. A sealing member 32 is liquid-tightly fitted in the opening at the downstream end of the large diameter portion 16 via an O-ring 33.

On the peripheral surface of the stationary blade 21, a plurality of protruding stationary blade blade portions 22 protruding in the radially outward direction are provided. The stationary blade blade 22 is inclined from the upstream side toward the downstream side while twisting in the right direction with respect to the axial center of the stationary blade 21, for example.

The upstream portion of the moving blade 25 is formed in a columnar shape, and a plurality of moving blade blade portions 26 projecting radially outward are provided on the peripheral surface thereof. Contrary to the stationary blade blade portion 22, the moving blade blade portion 26 is inclined from the upstream side to the downstream side while twisting leftward with respect to the axial center.

  A moving blade ring 28 is provided on the outer peripheral side of the moving blade 25 so as to surround the periphery of the moving blade blade portion 26. A flange portion 28a projecting radially outward is integrally provided at the downstream end portion of the moving blade ring 28, and a magnet M is fixed to the moving blade ring 28 on the upstream side of the flange portion 28a. Yes. The moving blade 25, the moving blade ring 28, and the magnet M are integrally rotated around an axis substantially parallel to the water supply flow path.

  As shown in FIG. 4, the magnet M has a cylindrical shape, and N and S poles are alternately magnetized along the circumferential direction on the end surface.

  A bearing 34 that supports the rotor blade 25 in the axial direction is provided on the downstream side of the rotor blade 25. A shaft member 35 is fixed at the center of the bearing 34. The shaft member 35 extends from the center of the bearing 34 toward the upstream side, and is provided substantially parallel to the central axis of the cylindrical body 15, that is, substantially parallel to the flow path. The bearing 34 includes a sleeve 44 fixed to the inner peripheral surface of the sealing member 32, and a plurality of connecting members 43 provided radially from the axial center toward the inner peripheral surface of the sleeve 44. A shaft member 35 is fixed to the center of the member 43. The plurality of connecting members 43 are provided apart from each other in the circumferential direction, and are not closed between the connecting members 43, and a gap that allows the flow of running water is formed.

  The shaft member 35 penetrates the shaft center of the rotor blade 25, the downstream end of the rotor blade 25 is supported on the bearing 34 so as to be rotatable (slidable), and the rotor blade 25 is moved in the radial direction by the shaft member 35. While being regulated, the shaft member 35 can be rotated.

A stator 50 is provided on the outer side of the small-diameter portion 18 of the cylindrical body 15 so as to face the axial end surface (the magnetized surface in which the N pole and the S pole are magnetized) on the upstream side of the magnet M. .
FIG. 5 shows a perspective view of the stator 50.

  The stator 50 includes a cylindrical yoke 40 and a coil 36 housed in a space surrounded by the yoke 40 and wound in a cylindrical shape. The yoke 40 is formed by combining three first to third yokes 41 to 43, both of which are made of a magnetic material.

  The first yoke 41 has an inner peripheral portion that is provided inside the coil 36 and faces the inner peripheral side portion of the coil 36, and has a diameter substantially perpendicular to the inner peripheral portion from one axial end portion of the inner peripheral portion. And a plurality of inductors 51 protruding outward. The plurality of inductors 51 are spaced apart from each other in the circumferential direction at equal intervals, and face the axial end surface of the coil 36.

  The second yoke 42 is provided on the outer side of the coil 36 and opposed to the outer peripheral side portion of the coil 36, and protrudes radially inward from the one end portion in the axial direction at the outer peripheral portion at a substantially right angle to the outer peripheral portion. And a plurality of inductors 52 provided. The plurality of inductors 52 are spaced apart from each other in the circumferential direction at equal intervals, and face the axial end surface of the coil 36.

  The inductors 51 of the first yoke 41 and the inductors 52 of the second yoke 42 are arranged alternately and spaced apart from each other along the circumferential direction. These inductors 51 and 52 are opposed to one axial end face of the coil 36. As shown in FIG. 1, one axial end surface of the coil 36 has an axial end surface (magnetized surface) on the upstream side of the magnet M with the inductors 51 and 52 and the flange portion 17 of the cylindrical body 15 interposed therebetween. Opposite to. That is, the inductors 51 and 52 face the axial end surface (magnetized surface) on the upstream side of the magnet M.

  The third yoke 43 has a ring plate shape provided opposite to the other axial end surface of the coil 36 (an axial end surface opposite to the axial end surface to which the inductors 51 and 52 are opposed). The other end of each of the yoke 41 and the second yoke 42 in the axial direction (the axial end opposite to the axial end on the side where the inductors 51 and 52 are provided) is coupled.

  Next, the operation of the faucet generator 1 and the faucet device 3 will be described.

  When the user holds his hand under the spout 6 of the faucet device 3, the sensor 7 senses this, the control unit 57 opens the electromagnetic valve 8, and the water supply passage 10 is communicated. Thereby, running water is supplied to the inside of the cylindrical body 20 of the faucet generator 1, and the water that flows inside the cylindrical body 20 is discharged from the water outlet 6. When the user moves his hand away from under the spout 6, the solenoid valve 8 is closed and water automatically stops.

  The flowing water that has flowed into the cylindrical body 20 flows on the conical surface of the stationary blade 21 and is diffused in the radially outward direction. In the structure illustrated in FIG. Thus, it flows through the stationary blade flow path 23 between the stationary blade blade portions 22.

  The swirling flow that has flowed through the stationary blade flow path 23 flows into the moving blade flow path 27 between the moving blade blade portions 26 and collides with the upper inclined surface of the moving blade blade portion 26. In this specific example, the swirl flow that flows into the blade flow path 27 is a flow swirled in the right direction with respect to the axial center. Rotate clockwise. The flowing water that has flowed through the rotor blade flow path 27 flows in the axial direction through the small-diameter portion 20 b of the cylindrical body 20, passes through the cylindrical body 20, and reaches the spout 6.

  When the rotor blades 25 are rotated by receiving the above-described force from the flowing water, the magnet M fixed thereto is also rotated. When the magnet M rotates, the inductors 51 and 52 facing the axial end surface on the upstream side of the magnet M in which the N pole and the S pole are alternately magnetized along the circumferential direction, and these are integrated. The polarity of the yokes 41 and 42 is changed. Thereby, the direction of the interlinkage magnetic flux with respect to the coil 36 is changed, and an electromotive force is generated in the coil 36 to generate power. The electric power generated by the power generation is sent to the charger 56, and after being charged, for example, used for driving the electromagnetic valve 8, the sensor 7, and the control unit 57.

  In the present embodiment, the moving blade ring 28 provided so as to surround the periphery of the moving blade blade portion 26 functions as a partition wall that separates the moving blade flow path 27 and the inner wall surface of the cylindrical body 15. Therefore, more flowing water flows through the moving blade passage 27 inside the moving blade ring 28. By increasing the flow rate flowing along the moving blade portion 26, the rotational force of the moving blade 25 is further increased, and the power generation capacity can be increased.

  In addition, by providing the magnet M so as to surround the periphery of the moving blade blade portion 26 without providing the moving blade ring 28, the radially outward direction of the flowing water flowing through the moving blade flow path 27 by the inner peripheral surface of the magnet M. You may make it prevent the outflow to.

  Further, in the present embodiment, since the coil 36 is configured to be opposed to the axial end surface of the magnet M, the radial dimension is made smaller than in the case where the coil 36 is arranged to be opposed to the radially outward direction of the magnet M. be able to. Further, since the coil 36 is not disposed outside the rotor blade 25 in the radial direction, the radial dimension of the rotor blade 25 can be increased, and the amount of power generation can be increased.

  As the force acting on the moving blade 25, the fixing member is constituted by the force biased downstream by the pressure of the flowing water flowing from the upstream side and the magnetic attractive force acting between the magnet M and the inductors 51 and 52. There is a force attracted to the inductors 51 and 52 side. Here, when the urging force due to the water flow pressure and the force attracted to the inductors 51 and 52 by the magnetic attraction force act in the same direction, the moving blade 25 is applied to the bearing 34 particularly when the magnetic force of the magnet is strong. There is a concern that the durability of the rotor blades 25 may be reduced due to a decrease in the rotational performance of the rotor blades 25 and wear at the sliding portion between the rotor blades 25 and the bearings 34.

  However, in the present embodiment, since the inductors 51 and 52 are opposed to the axial end surface on the upstream side of the magnet M, the moving blade 25 is caused by the magnetic attractive force acting between the magnet M and the inductors 51 and 52. Receives the suction force upstream. This force is in a direction opposite to the direction of the force urged downstream by the pressure of the flowing water flowing from the upstream side, and thus the urging force downstream acts on the rotor blade 25 excessively. I can prevent that. As a result, it is possible to provide a highly reliable product by preventing a decrease in the rotational performance of the moving blade 25 and a decrease in durability at the sliding portion between the moving blade 25 and the bearing 34.

  In the faucet generator according to the present embodiment, as shown in FIG. 6, the moving blade 25 may be configured to rotate integrally with the shaft member 29 with respect to the bearing 34.

  The shaft member 29 passes through the rotational center of the moving blade 25 and is fixed to the moving blade 25. The upstream end portion of the shaft member 29 protrudes upstream from the moving blade 25 and is engaged with the stationary blade 21 so as to be rotatable (slidable). The downstream end of the shaft member 29 protrudes downstream from the rotor blade 25 and engages with the bearing 34 so as to be rotatable (slidable). The rotor blade 25 rotates integrally with the shaft member 29 while its lower end is supported so as to be rotatable (slidable) with respect to the bearing 34.

  Also in this configuration, since the inductors 51 and 52 are opposed to the axial end surface on the upstream side of the magnet M, the magnetic attraction force acting between the magnet M and the inductors 51 and 52 causes the moving blade 25 to move. Therefore, it is possible to prevent the urging force on the downstream side from acting excessively. As a result, it is possible to provide a highly reliable product by preventing a decrease in the rotational performance of the moving blade 25 and a decrease in durability at the sliding portion between the moving blade 25 and the bearing 34.

FIG. 7 is a schematic cross-sectional view of a faucet generator according to another embodiment of the present invention.
FIG. 8 is a schematic perspective view of a stator in the faucet generator.

  The coil 36 is not necessarily provided on the upstream side of the magnet M, and the coil 36 is provided outside the diameter of the magnet M in the present embodiment.

  The cylindrical body 100 has a stepped shape including a small diameter portion 101, a large diameter portion 102, and a flange portion 103, and is arranged so that the central axis direction thereof is substantially parallel to the direction in which flowing water flows through the water supply channel. The The cylindrical body 100 is disposed with the large-diameter portion 101 facing the upstream side and the small-diameter portion 102 facing the downstream side.

  A sealing member 105 is liquid-tightly fitted into the opening at the downstream end of the large diameter portion 102. A stationary blade 21 is fixed inside the small diameter portion 101, a moving blade 25 is rotatably provided inside the large diameter portion 102, and is fixed to the inner peripheral surface of the sealing member 105. A bearing 34 is provided.

  The shaft member 35 fixed to the center of the bearing 34 passes through the shaft center of the rotor blade 25, and the downstream end of the rotor blade 25 is supported on the bearing 34 so as to be rotatable (slidable). The shaft member 35 is rotatable around the shaft member 35 while being restricted from moving in the radial direction.

A stator 60 is provided outside the cylindrical body 100.
FIG. 8 is a perspective view of the stator 60.

  The stator 60 includes first to third yokes 61 to 63 made of a magnetic material, and a coil 36 that is housed in a space surrounded by the yokes 61 to 63 and wound in a cylindrical shape.

  The first yoke 61 is provided on the inner side of the coil 36 and is opposed to the inner peripheral side portion of the coil 36, and from the one end portion in the axial direction of the inner peripheral portion 72 to the inner peripheral portion 72. And a plurality of inductors 71 provided so as to protrude radially inward at a right angle. The plurality of inductors 71 are spaced apart from each other in the circumferential direction at equal intervals and face the axial end surface (magnetization surface) on the upstream side of the magnet M.

  The second yoke 62 is provided on the outer side of the coil 36 and opposed to the outer peripheral side portion of the coil 36, and the radially inner side of the outer peripheral portion 82 from one end portion in the axial direction to the outer peripheral portion at a substantially right angle. And a plurality of inductors 81 provided so as to protrude. The plurality of inductors 81 are spaced apart from each other in the circumferential direction at equal intervals, and face the upstream axial end surface of the coil 36 and the upstream axial end surface (magnetized surface) of the magnet M.

  The inductors 71 of the first yoke 61 and the inductors 81 of the second yoke 62 are arranged alternately and spaced apart from each other along the circumferential direction. The coil 36 is provided on the outer peripheral side of the large-diameter portion 102 of the cylindrical body 100 outside the diameter of the magnet M. The inductors 71 and 81 sandwich the flange portion 103 of the cylindrical body 100 between them and It faces the axial end surface (magnetized surface) on the upstream side of M.

  The third yoke 63 (see FIG. 7) has a ring plate shape facing the axial end surface on the downstream side of the coil 36, and each downstream side of the first yoke 61 and the second yoke 62. Is coupled to the axial end of the.

  Also in this embodiment, since the inductors 71 and 81 are opposed to the axial end face on the upstream side of the magnet M, the moving blade 25 is caused by the magnetic attractive force acting between the magnet M and the inductors 71 and 81. Receives force drawn upstream. This force is in a direction opposite to the direction of the force urged downstream by the pressure of the flowing water flowing from the upstream side, and thus the urging force downstream acts on the rotor blade 25 excessively. I can prevent that. As a result, it is possible to provide a highly reliable product by preventing a decrease in the rotational performance of the moving blade 25 and a decrease in durability at the sliding portion between the moving blade 25 and the bearing 34.

  In the faucet generator according to the present embodiment, as illustrated in FIG. 9, the moving blade 25 may be configured to rotate integrally with the shaft member 106 relative to the bearing 34.

  The shaft member 106 passes through the rotational center of the moving blade 25 and is fixed to the moving blade 25. The upstream end of the shaft member 106 protrudes upstream from the rotor blade 25 and engages with the stationary blade 21 so as to be rotatable (slidable). The downstream end of the shaft member 106 protrudes downstream from the rotor blade 25 and engages with the bearing 34 so as to be rotatable (slidable). The rotor blade 25 rotates integrally with the shaft member 106 while its lower end is supported rotatably (slidable) with respect to the bearing 34.

  Also in this configuration, since the inductors 71 and 81 are opposed to the axial end surface on the upstream side of the magnet M, the magnetic attraction force acting between the magnet M and the inductors 71 and 81 causes the moving blade 25 to move. Therefore, it is possible to prevent the urging force on the downstream side from acting excessively. As a result, it is possible to provide a highly reliable product by preventing a decrease in the rotational performance of the moving blade 25 and a decrease in durability at the sliding portion between the moving blade 25 and the bearing 34.
