Description

  The present invention relates to a tank device with a generator.

  2. Description of the Related Art Conventionally, a tank apparatus is known in which a water-flow generator that generates electricity by a flow of water supplied to a tank is provided in a tank attached to a toilet. (Patent Document 1) A conventional tank apparatus includes a generator in a water channel through which water supplied to the tank flows, and the impeller of the generator is generated by the water flow flowing in the water channel when the tank is supplied after cleaning the toilet bowl. The power is generated by rotating the. The generated electric power is used as a power source for electronic devices related to toilet cleaning operations.

However, in the conventional tank apparatus, since the generator is provided in the water channel, in the flush toilet, which is often used the reclaimed water that has been used once or the rainwater, Foreign matter contained in middle water or the like is likely to be caught between the impeller of the machine and the inner wall of the water channel, and the generator tends to malfunction or be damaged. Especially when the impeller does not rotate due to damage, it becomes difficult for water to be discharged from the water channel when the tank is supplied with water, and it takes a very long time for the tank to become full. Therefore, there is a big problem that the user cannot perform toilet cleaning.

Therefore, it is conceivable to provide an impeller outside the water channel instead of providing an impeller inside the water channel. That is, it is conceivable to generate electricity by causing the impeller provided outside the waterway to collide with water injected from the outlet of the waterway and rotating the impeller.

Here, in general, the tank has a horizontally long shape (long in the width direction) in order to suppress the length of the toilet bowl in the front-rear direction and secure a space in front of the toilet bowl.

However, when the generator is installed in the tank having such a structure, when the impeller is disposed in the tank to which the water for storage is supplied, the rotating shaft of the impeller is perpendicular to the width direction of the tank in a top view. If the impeller is installed in such a way that the radial direction of the impeller (the direction in which the blade extends from the rotation axis) and the width direction of the tank (longer than the length in the front-rear direction of the tank) are parallel, high power generation Even when a large impeller is used to obtain the amount, a sufficient space can be provided between the radially outermost end of the impeller and the inner wall of the tank. Therefore, there is no problem that the inner wall of the tank and the impeller interfere with each other due to an assembly error or the rotational vibration of the impeller when the distance is too close.

However, when the impeller is arranged in this way, the water adhering to the impeller scatters radially around the rotation axis due to centrifugal force. Therefore, in order to fill the tank with a part of the water that has been scattered radially from the opening of the upper end of the overflow pipe provided so that the water level in the tank does not become a predetermined level or more, There is a problem that extra water must be supplied and waste water is generated. In order to solve this, a method of reducing the flow rate of water sprayed onto the impeller so that water does not scatter from the impeller is conceivable, but this means that the rotation speed of the impeller falls and the power generation amount decreases. Problems arise.

Japanese Patent Laid-Open No. 2004-257095

The present invention has been made in order to solve the above-described problem, and it is difficult to cause malfunction and damage, and further, water scattered from the impeller enters the overflow pipe when water is supplied to the tank without reducing the power generation amount. It aims at providing the tank apparatus with a generator which can suppress this.

The tank device with a generator according to the present invention is a tank device with a generator in which a generator is provided inside the tank, a tank for storing water to be supplied to a toilet, and a rotation device provided in the tank. An impeller having a plurality of blades extending radially from the shaft, a nozzle for injecting water toward the blades of the impeller to rotate the water supply and the impeller into the tank, and the rotation of the impeller A magnet that rotates with the magnet, a coil that generates an electromotive force by the rotation of the magnet, and an overflow pipe that discharges water from the opening provided above the tank so that the water level in the tank does not exceed a predetermined level. The nozzle injects water into the space in the tank, and the impeller is arranged downstream of the nozzle, and the rotation shaft of the impeller Direction, there is arranged so that the width direction perpendicular of the tank in a top view the impeller, viewed from the top, characterized in that provided in the forward or backward than the overflow pipe

In the present invention configured as above, since the impeller is provided in front or behind the overflow pipe in the top view, the amount of water scattered from the impeller by the centrifugal force is the largest. The overflow pipe is not located in the direction perpendicular to the axial direction of the car's rotating shaft. Therefore, it is possible to suppress the water scattered from the impeller from entering the overflow pipe during tank water supply without reducing the power generation amount.

In the present invention, preferably, the impeller is provided on a side of the overflow pipe in a front view.

In the present invention configured as described above, since the impeller is provided on the side of the overflow pipe in the front view, the splash water that is ejected from the nozzle and collides with the impeller in the top view is generated. Since the overflow pipe is not positioned in front of or behind the scattered impeller, it is possible to more reliably prevent water scattered from the impeller from entering the overflow pipe when the tank is supplied with water.

  According to the tank device with a generator of the present invention, it is difficult to cause malfunction and damage, and further, it is possible to prevent water scattered from the impeller from entering the overflow pipe when water is supplied to the tank without reducing the power generation amount.

The front view of the tank apparatus 1 with a generator which concerns on embodiment of this invention. The top view of the tank apparatus 1 with a generator which concerns on embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view of a tank device 1 with a generator according to an embodiment of the present invention, and FIG. 2 is a top view of the tank device 1 with a tank lid 2 removed. A tank device 1 with a generator according to an embodiment of the present invention is arranged on an upper portion of a toilet (not shown), and has a tank 5 for storing water to be supplied to the toilet and an opening above the tank 5. The tank lid 2 is covered, and the generator 27 is arranged inside the tank 5.

A drain port 7 is provided at the bottom of the tank 5, and a flapper valve 9 covering the drain port 7 is pulled up by operating the operation lever 11 to supply water in the tank 5 to the toilet. The flapper valve 9 is rotatably attached to a pedestal 13 provided at the upper part of the drain port 7. The lower end of the overflow pipe 15 is connected to the pedestal 13, and the water flowing from the inlet 17 at the upper end of the overflow pipe is discharged from the drain port 7 to a toilet (not shown) through the flow path inside the pedestal 13. The

  The side wall 5a of the tank 5 is provided with a water supply pipe through-hole 10 for penetrating a water supply pipe 19 that guides water from the water supply source to the inside of the tank. The water supply pipe 19 that passes through the water supply pipe through-hole 10 It is connected to a ball tap 21 provided inside the tank 5.

The ball tap 21 switches whether or not the water from the nozzle 25 connected to the ball tap 21 is jetted when the float 23 connected to the ball tap 21 moves up and down according to the water level in the tank. Specifically, when the operation lever 11 is operated and the water in the tank is discharged from the drain port 7 and the water level in the tank decreases, the water is injected from the nozzle 25 and the water injected from the nozzle 25 is the tank 5. When the water level in the tank reaches the full water level, the injection from the nozzle 25 is stopped.

A shaft 12 is connected to the operation lever 11, and when the operation lever 11 is operated, the shaft 12 winds a wire 16 that connects the flapper valve 9 and the shaft 12 to rotate the flapper valve 9. It is configured. Further, the shaft 9 is disposed through a shaft through hole 14 provided in the side wall 5 b of the tank 5. Here, the water supply pipe through hole 10 and the shaft through hole 14 facilitate the replacement of the water in the tank 5 and the air outside the tank 5 when the water in the tank 5 is drained, so that the water in the tank 5 is smoothly drained. Thus, it plays a role as an air introduction hole for introducing air from the outside of the tank 5.

Inside the tank 5, a generator 27 is provided at a position higher than the full water level. The generator 27 is attached to the rotating shaft 29, the impeller 33 having a plurality of blades 31 extending radially from one end side of the rotating shaft 29, and the magnet that rotates integrally with the rotating shaft 29. 35 and a coil 37 provided so as to surround the magnet 35. Note that both ends of the rotary shaft 29 are pivotally supported by the tank 5.

Here, since the water sprayed from the nozzle 25 is sprayed toward the blade 31 of the impeller 33, the impeller 33 rotates when the water sprayed from the nozzle 25 collides with the blade 31. Therefore, when the water jetted from the nozzle 25 collides with the blade 31, the water is scattered around the periphery, or the water attached to the impeller 31 due to the centrifugal force is scattered around due to the rotation of the impeller 31. .

The magnet 35 and the coil 37 are housed in a casing 39 attached to the inner wall of the tank 5, and the water splashed when the water sprayed from the nozzle 25 collides with the impeller 33 is magnetized by the casing 39. 35 and the coil 37 are not exposed.

The end portion of the rear side of the overflow pipe 15 is arranged apart by L ₂ than the end of the front side of the impeller 33 in top view. As shown by the arrows in FIG. 1, since water scatters in the radial direction around the rotation shaft 29, a large amount of water scatters at the left and right positions of the impeller 33 in a top view. However, in this way, the scattered water can hardly flow into the overflow pipe 15 by separating the position of the overflow pipe 15 and the position of the impeller 33 in the front-rear direction.

Further, the left end of the overflow pipe 15 is arranged apart by L ₁ than the right end portion of the impeller 33 in a front view. The jet water from the nozzle 25 that has collided with the blade 31 scatters in the front-rear direction as indicated by arrows in FIG. 2 after the collision. Thus, by separating the position of the overflow pipe 15 and the position of the impeller 33 in the left-right direction, it is possible to make it difficult for water that has collided with the blade 31 and scattered to flow into the overflow pipe 15.

Further, arrangement of the overflow tube 15 and the impeller 33, so that towards the L ₁ is greater than L _2. Since the tank 5 is a horizontally long shape, by increasing the direction of distance L ₁ in the width direction than the front-rear direction of the distance L _2, it will be located in the most amount of scattered less water position, more reliably, Water can be prevented from entering the overflow pipe 15.

By preventing the water scattered from the impeller 33 from entering the inlet hole 17 of the overflow pipe 15 in this way, a part of the water jetted from the nozzle 25 that is also used for tank water supply is supplied during tank water supply. It can be suppressed that the amount of water more than the amount necessary for filling the tank 5 is filled before the tank 5 reaches the full water level due to entering the inflow hole 17 of the overflow pipe 15. Therefore, in order to secure the amount of power generation, it is possible to suppress the generation of waste water even when water is sprayed from the nozzle 25 vigorously to the impeller 33 and water is scattered from the impeller 33. Become.
