The lower LED chamber 45 is provided between the first and second openings 42 a and 42 b at the lower end of the in-tank protrusion 4. Further, the lower LED chamber 45 is divided into two by a partition wall 43.

  Inside each LED chamber 45, a plurality of light emitting diodes (LEDs) 46 as light emitting means (illuminators) are arranged side by side along the outer peripheral edge of the in-vessel protrusion 4.

  As shown in FIGS. 5 to 7, a lock pin insertion hole 49 is provided at an intermediate position of the upper LED chamber 45 in the in-tank protruding portion 4, and the flow path partition member 3 is connected to a male screw member as will be described later. 2, the flow partition member 3 is prevented from rotating with respect to the male screw member 2 by a lock pin (not shown) inserted into the lock pin insertion hole 49.

  As shown in FIGS. 2, 5, etc., a front closing plate 5 is detachably attached to a part of the front side opening in the in-tank protrusion 4. The front blocking plate 5 is cut off at a portion corresponding to the LED chamber 45 so as to block only the region where the first and second flow paths 43a and 43b are formed.

  As shown in FIGS. 6, 7A and 7B, intermediate portions (parts) of the first and second flow paths 43a and 43b are configured as first and second power generation chambers 7a and 7b.

  In the first and second power generation chambers 7a and 7b, support columns 71 and 71 are respectively attached at the center positions. One end side (fixed end side) of band-plate-shaped oscillating plates 72 and 72 including piezoelectric elements is fixed to both sides of each support 71 and 71. And the other end part side (oscillation end part side) of the rocking | swiveling plates 72 and 72 is arrange | positioned at the both-sides edge part of each flow path 43a, 43b.

  In the first embodiment, the swing plate 72 is configured as a piezoelectric element plate (piezoelectric element film) including a piezoelectric element.

  Furthermore, a lead wire such as a copper wire is incorporated in the support column 71 that supports the swing plate 72, and power generated by the piezoelectric element of the swing plate 72 is passed through the lead wire as will be described later. Can be taken out.

  Water turbines 75 and 75 are attached to the power generation chambers 7a and 7b at positions corresponding to the rocking end portions of the rocking plates 72 so as to be rotatable about their axis. When the water wheels 75 and 75 rotate, the blades of the water wheels 75 and 75 continuously and sequentially collide with the rocking end portions of the rocking plates 72.

  In the first embodiment, the movable body is constituted by the water wheel 75.

  The water turbines 75 and 75 are different from those rotated by hot water flowing in from the axial direction, and are rotated by hot water flowing in from the radial direction or circumferential direction and flowing out in the radial direction or circumferential direction. Is. Further, as described above, the water turbine 75 is made to swing by swinging the swing plate 72 with the blades. Needless to say, it is different from the water turbine (turbine) that drives the generator.

  Further, on the inner peripheral side of the power generation chambers 7a and 7b, in other words, at a position closer to the first and second communication holes 41a and 41b than the swinging plate 72 in the power generation chambers 7a and 7b, a front view mountain-shaped water flow control is performed. Plates 73 and 73 are attached. The central top portions of the water flow control plates 73 and 73 are disposed to face the center positions of the first and second communication holes 41a and 41b. Accordingly, the hot water flowing into the flow paths 43a and 43b from the communication holes 41a and 41b is guided to both sides of the flow paths 43a and 43b by the water flow control plates 73 and 73 so as to be supplied to the positions of the water turbines 75 and 75. It has become.

  Further, on the outer peripheral side of the power generation chambers 7a and 7b, in other words, at a position closer to the first and second openings 42a and 42b than the swing plate 72 in the power generation chambers 7a and 7b, a water flow control plate 74 having a front view mountain type. 74 are attached. The central top portions of the water flow control plates 74 and 74 are arranged to face the central positions of the first and second openings 42a and 42b. Accordingly, the hot water flowing into the flow paths 43a and 43b from the openings 42a and 42b is guided to both sides of the flow paths 43a and 43b by the water flow control plates 74 and 74 and supplied to the positions of the water turbines 75 and 75. It has become.

  In the power generation chambers 7a and 7b having the above configuration, for example, when hot water flows into the first and second flow paths 43a and 43b from the first and second communication holes 41a and 41b, the hot water is placed on both sides by the water flow control plates 73. Guided to water turbines 75 and 75. Thereby, hot water circulates so as to push the blades of the water turbines 75 and 75, and the water wheels 75 and 75 rotate. At this time, the blades of the water turbines 75 and 75 continuously collide with the oscillating end of the oscillating plate 72, and the oscillating end of the oscillating plate 72 oscillates (vibrates) quickly in small increments. The element is activated to generate a predetermined electric power.

  Conversely, when hot water flows into the first and second flow paths 43 a and 43 b from the first and second openings 42 a and 42 b, the hot water is guided to the water turbines 75 and 75 on both sides by the water flow control plate 74. As a result, the turbines 75 and 75 are rotated in the same manner as described above, and the swing plate 72 is vibrated little by little to generate electric power.

  Although illustration is omitted, the flow path partition member 3 is provided with a control circuit for controlling lighting (light emission) of the LED 46. Further, the support (lead wire) 71 of the swing plate 72 of the power generation chambers 7a and 7b and the control circuit are electrically connected. Thus, when the swing plate 72 swings and electric power is generated, the LED 46 is turned on by the electric power.

  As shown in FIGS. 1-4 etc., the cover member 9 which covers the front side is attached to the protrusion part 4 in a tank so that attachment or detachment is possible.

  The cover member 9 includes a circular front wall and an outer peripheral wall provided on the outer peripheral edge on the rear surface side of the front wall. The front wall covers the front side of the in-tank protruding portion 4, and the outer peripheral wall covers the tank. The outer peripheral side surface of the inner protrusion 4 is covered.

  In the front wall of the cover member 9, a portion corresponding to the LED 46 attached to the in-tank protrusion 4 is constituted by a transparent window 91 made of synthetic resin. Therefore, when the LED 46 is turned on, the illumination light is irradiated forward through the transparent window 91.

  In the outer peripheral wall of the cover member 9, openings 92 and 92 are formed corresponding to the first and second openings 42 a and 42 b of the in-tank protrusion 4. Therefore, the hot water discharged from the openings 42 a and 42 b of the in-tank protrusion 4 is discharged into the bathtub through the openings 92 and 92 of the cover member 9. Furthermore, hot water in the bathtub is sucked from the first and second openings 42 a and 42 b of the in-tank protrusion 4 through the openings 92 and 92 of the cover member 9.

  The flow path partition member 3 to which the cover member 9 is attached is detachably attached to the male screw member 2 attached to the bathtub side wall W by a known attachment means. At this time, the cylindrical portion 31 of the flow path partition member 3 is inserted into the inner cylinder portion 11 of the outside-tubing attachment member 1 disposed inside the male screw member 2.

  Needless to say, in the present invention, the procedure for assembling the hot water supply adapter is not limited, and any procedure may be used.

  In this assembled state, as shown in FIG. 1, an O-ring 81 is disposed between the inner cylindrical portion 11 of the outer tank attachment member 1 and the cylindrical portion 31 of the flow path partition member 3, and the O-ring 81 The water-tightness between the members 11 and 31 is achieved, and the in-tank protruding portion 4 of the channel partitioning member 3 and the male screw member 2 are provided by the packing 84 provided on the rear surface of the in-tank protruding portion 4 of the channel partitioning member 3. Watertightness between the flange portion 25 and the flange portion 25 is achieved.

  In the hot water outlet adapter thus assembled in the bathtub, the inner flow path A passes through the first communication hole 41a of the flow path partition member 3 to the first flow path 43a (first power generation chamber 7a) of the flow path partition member 3. The first flow path 43 a (first power generation chamber 7 a) is communicated (opened) into the bathtub through the first opening 42 a and the opening 92 of the cover member 9. The outer flow path B communicates with the second flow path 43b (second power generation chamber 7b) of the flow path partition member 3 through the second communication hole 41b of the flow path partition member 3, and the second flow path 43b ( The second power generation chamber 7b) is communicated (opened) into the bathtub through the second opening 42a and the opening 92 of the cover member 9.

  In the present embodiment, the inner flow path A and the first flow path 43a (first power generation chamber 7a) constitute either the forward flow path or the return flow path, and the outer flow path. The remaining flow path is configured by the path B and the second flow path 43b (second power generation chamber 7b).

  As described above, the hot water supply adapter according to the present embodiment is connected to the outdoor water heater with respect to the two outer pipe connection portions 1a and 1b in the outside mounting member 1 when connecting the pipe to the outdoor water heater. Non-polar type that can be used with either pipe or return pipe connected.

  For example, in the state where the outgoing pipe is connected to the first outer pipe connecting portion 1a and the return pipe is connected to the second outer pipe connecting portion 1b, when the reheating process is performed, the hot water supplied from the water heater is connected to the outgoing pipe and the first outer pipe. 1 is introduced into the inner flow path A through the outer pipe connecting portion 1a, and the hot water is supplied into the bathtub from the first opening 42a through the inner flow path A and the first flow path 43a of the flow path partition member 3. Is done.

  On the suction side, the return pipe and the outer flow path B are set to a negative pressure by the suction force of the water heater, so the second flow path 43b of the flow path partition member 3 also has a negative pressure. Accordingly, the hot water (water) in the bathtub is sucked into the second flow path 43b from the second opening 42b of the flow path partition member 3, and returned to the hot water heater through the outer flow path B and the return pipe.

  Therefore, when pipes are connected in this way, the forward flow path is constituted by the inner flow path A and the first flow path 43a, and the return flow path is constituted by the outer flow path B and the second flow path 43b.

  At the time of reheating, the LED 46 provided on the in-tank protrusion 4 is turned on. That is, on the outgoing flow path side, hot water flowing into the first flow path 43a from the first communication hole 41a is guided to both sides of the flow path 43a by the water flow control plate 73 to rotate the water wheels 75 and 75. By this rotation, the blades of the water turbines 75 and 75 continuously and sequentially collide with the oscillating end portions of the oscillating plates 72, and the oscillating plates 72 vibrate quickly in small increments. Due to this vibration, the piezoelectric element of each rocking plate 72 is operated to generate electric power.

  On the return flow path side, the hot water sucked into the second flow path 43b from the second opening 42b is guided to both sides of the flow path 43b by the water flow control plate 74, and the water turbines 75 and 75 are rotated. Similarly, power is generated.

  Thus, the LED 46 is lit by the electric power generated in the power generation chambers 7a and 7b on both the forward flow path side and the return flow path side. Further, the illumination light of the LED 46 thus lit is irradiated in front of the hot water supply adapter, and a light effect can be given to the hot water in the bathtub, so that a comfortable bathing environment can be obtained.

  On the other hand, when the reheating process is performed in a state where the outgoing pipe is connected to the second outer pipe connecting portion 1b and the return pipe is connected to the first outer pipe connecting portion 1a, the circulation is performed in the reverse direction to the above. That is, hot water from the water heater passes through the forward pipe, the second outer pipe connecting portion 1b, the outer flow path B, and the second flow path 43b (second power generation chamber 7b), and the second opening 42b and the opening of the cover member 9 The hot water in the bathtub is sucked from the opening 92 of the cover member 9 and the first opening 42a, and the first flow path 43a (first power generation chamber 7a), the inner flow path A, It returns to the water heater through the first outer pipe connecting portion 1a and the return pipe.

  Therefore, when the pipes are connected in this way, the return channel is constituted by the inner channel A and the first channel 43a, and the forward channel is constituted by the outer channel B and the second channel 43b.

  Further, even when the pipes are connected in this way, the power is generated by the power generation chambers 7a and 7b and the LED 46 is lit as described above.

  In addition, the hot water supply adapter of this embodiment performs hot water beam by a double conveyance system. That is, during hot water supply, hot water is supplied from the water heater to both the return pipe and the return pipe, and the hot water passes through the inner and outer flow paths A and B of the hot water supply adapter and the first and second flow paths 43a and 43b. The first and second openings 42a and 42b are supplied into the bathtub.

  Even during hot water pouring, the power is generated by the power generation chambers 7a and 7b, and the LED 46 is lit as described above.

  As described above, according to the hot water supply adapter according to the first embodiment, the LED 46 can be turned on by self-power generation at the time of chasing and the like, and a predetermined effect effect by light can be given in the bathtub.

  Furthermore, since the hot water supply adapter according to the present embodiment generates power using a piezoelectric element, that is, the swing plate 72 as a piezoelectric element is swung by a blade of a water wheel 75 to generate power. Therefore, the structure of the power generation unit can be simply finished, and downsizing can be achieved. In particular, the hot water supply adapter according to the present embodiment can more reliably simplify the structure and reduce the size as compared with the case of using a generator having a complicated structure that generates power by rotating a turbine (turbine). Can do.

  In the present embodiment, the flow control plates 73 and 74 are provided on the upstream side of the power generation chambers 7a and 7b so that the hot water sufficiently circulates through the position of the water turbine 75. Therefore, the water turbine 75 is rotated vigorously. be able to. Therefore, the oscillating plate 72 can be sufficiently vibrated to sufficiently operate the piezoelectric element, a sufficient amount of power generation can be ensured, and the LED 46 can be lighted more reliably.

  Further, since the flow control plates 73 and 74 are arranged on both the upstream side and the downstream side of the swing plate 72, when the swing plate 72 is about to be bent greatly, the swing end of the swing plate 72 is moved. Since the portion abuts against the flow control plates 73 and 74, the rocking plate 72 can be prevented from being greatly deformed. As described above, the flow control plates 73 and 74 can limit the swing (vibration) range of the swing plate 72. For this reason, for example, it is possible to effectively prevent a problem that the swing plate 72 is unexpectedly greatly deformed and cannot return to the original state before the deformation.

  In the present embodiment, since the power generation chambers 7a and 7b are provided on both the forward flow path side and the return flow path side, it is possible to secure a larger amount of power generation than in the case where the power generation chamber is provided only on one side. The LED 46 can be lighted more reliably.

Second Embodiment

As shown in these drawings, the hot water supply adapter according to the second embodiment is composed of an outside tank attachment member 1, a male screw member 2, a flow path partition member 3, and power generation units 6a and 6b. As prepared.

  In this 2nd Embodiment, the tank outer attachment member 1 and the external thread member 2 are the substantially the same structures as the external tank attachment member 1 and the external thread member 2 of the said 1st Embodiment.

  As shown in FIGS. 14 to 16, the LED chamber 45 provided in the in-tank protrusion 4 of the flow path partition member 3 extends from the first opening 41 a to the second opening 42 b along the outer peripheral edge of the in-tank protrusion 4. Is formed. In the LED chamber 45, a plurality of LEDs 46 as light emitting means (illuminators) are attached side by side along the outer peripheral edge of the in-tank protrusion 4.

  As shown in FIGS. 11 to 15, the front side opening of the in-tank protrusion 4 is detachably attached to the outer peripheral wall 42 of the front closing plate 5 so as to close the entire opening.

  A portion of the front closing plate 5 corresponding to the LED chamber 45 is constituted by a transparent window 51 made of transparent synthetic resin. And when LED46 lights, the illumination light will be irradiated ahead of the protrusion part 4 in a tank through the through-hole window 51. FIG.

  9, the rear surface side of the outer peripheral edge of the rear wall 41 of the in-tank protrusion 4 is well-known on the front surface side of the flange portion 25 of the male screw member 2, as shown in FIG. The attachment means can be detachably attached.

  Note that, in the hot water supply adapter of the second embodiment, unlike the hot water supply adapter of the first embodiment, the first and second flow paths 43a and 43b of the in-tank protruding portion 4 have power generation chambers 7a, 7b is not provided, and the power generation chambers 7a and 7b are provided in power generation units 6a and 6b described below. Therefore, in the second embodiment, the first and second flow paths 43a and 43b of the in-tank protrusion 4 are members for generating electric power, such as a swing plate 72, water flow control plates 73 and 74, A water wheel 75 or the like is not provided.

  First and second power generation units 6 a and 6 b are provided at positions corresponding to the first and second openings 42 a and 42 b on the outer peripheral side surface of the tank protrusion 4.

  As shown in FIGS. 13-17, the 1st and 2nd electric power generation unit 6a, 6b is a left-right symmetric shape, and has the substantially same structure. That is, each of the power generation units 6a and 6b includes a rectangular tubular casing 60 having both ends opened. The casing 60 is configured such that the front wall 61 is detachable. Further, mesh sheets 65 and 65 are attached to both end openings 63 and 64 of the casing 60. The mesh sheets 65 and 65 are configured to allow passage of hot water while preventing passage of balls 69 described later.

  In this embodiment, the inside of each casing 60, 60 in each power generation unit 6a, 6b is configured as a power generation chamber 7a, 7b, respectively.

  In each power generation chamber 7a, 7b, a plurality of balls (fluid particles) 69 are accommodated as movable bodies. As the ball 69, a rubber or the like can be suitably used, but the material is not particularly limited.

  In the second embodiment, the front wall 61 and the rear wall 62 of the casing 60 constitute a piezoelectric element wall. That is, the front wall 61 and the rear wall 62 are configured as piezoelectric element walls by providing a piezoelectric element plate including a piezoelectric element on at least a part of its inner surface. Therefore, electric power is generated when the ball 69 in the casing 60 collides with the front and rear walls (piezoelectric element walls) 61 and 62.

  Further, near the inner opening 63 and the outer opening 64 on the inner surface of the side wall of the casing 60, a water flow disturbing piece 66 is formed so as to protrude inward. The hot water flowing into the casing 60 (the power generation chambers 7a and 7b) from the inner opening 63 or the outer opening 64 and flowing out from the outer opening 64 or the inner opening 63 is sufficiently discharged by the water flow disturbing piece 66 in the power generation chambers 7a and 7b. It is disturbed and the state of the flow becomes turbulent. Therefore, the turbulent hot water flow causes the balls 69 of the power generation chambers 7a and 7b to flow vigorously and irregularly and strongly collide with the front wall 61 and the rear wall 62 as piezoelectric elements as described above. A predetermined power can be generated.

  As for the 1st and 2nd electric power generation units 6a and 6b, the peripheral part of the inner side openings 63 and 63 is detachably attached to the peripheral part of the 1st and 2nd opening 42a, 42b of the protrusion part 4 in a tank.

  Although illustration is omitted, also in the second embodiment, similarly to the first embodiment, the flow path partition member 3 is provided with a control circuit for controlling lighting (light emission) of the LED 46. In the state where the power generation units 6a and 6b are attached to the in-tank protrusion 4, the piezoelectric elements of the front and rear walls 61 and 62 of the power generation units 6a and 6b and the control circuit of the in-tank protrusion 4 are electrically connected. It has come to be. Therefore, the LED 46 is turned on by the electric power generated in each of the power generation chambers 7a and 7b.

  The flow path partition member 3 to which the power generation units 6a and 6b are attached is assembled to the male screw member 2 assembled to the bathtub side wall W in the same manner as in the first embodiment.

  In the second embodiment, the cover member 9 for covering the in-tank protruding portion 4 of the flow path partition member 3 is not provided as in the first embodiment.

  In the second embodiment, the other configuration is substantially the same as that of the first embodiment, and therefore, the same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted.

  In the second embodiment, either the forward flow path or the return flow path is determined by the inner flow path A, the first flow path 43a, and the internal flow path (first power generation chamber 7a) of the first power generation unit 6a. The remaining flow path is constituted by the outer flow path B, the second flow path 43b, and the internal flow path (second power generation chamber 7b) of the second power generation unit 6b.

  In the hot water supply adapter according to the present embodiment configured as described above, for example, in the state where the return pipe is connected to the first outer pipe connection portion 1a and the return pipe is connected to the second outer pipe connection portion 1b, The continuous flow path constituted by the inner flow path A, the first flow path 43a and the first power generation chamber 7a becomes the forward flow path, and the outer flow path B, the second flow path 43b and the second power generation chamber 7b. A continuous flow path constituted by the above becomes a return flow path.

  At the time of reheating, the hot water flowing through each of the power generation chambers 7a and 7b in the first and second power generation units 6a and 6b is disturbed by the water flow disturbing piece 66 and becomes turbulent as described above. 7a and 7b, the ball 69 flows vigorously and irregularly, and the ball 69 repeatedly and strongly collides with the front and rear walls 61 and 62 as the piezoelectric element wall, so that the piezoelectric element is activated and power is generated. To do. Further, the LED 46 is turned on by the electric power, and the illumination light is irradiated in front of the hot water supply adapter.

  On the other hand, when the outgoing pipe is connected to the second outer pipe connecting portion 1b and the return pipe is connected to the first outer pipe connecting portion 1a, a return flow path is constituted by the first flow path 43a and the first power generation chamber 7a. The channel B, the second channel 43b, and the power generation chamber 7b constitute a continuous channel.

  Further, even when the pipes are connected in this way, the power is generated in the power generation chambers 7a and 7b of the power generation units 6a and 6b, and the LED 46 is lit as described above.

  Note that the hot water supply adapter of the second embodiment performs hot water beaming by the double conveyance method, as in the first embodiment. That is, at the time of hot water supply, hot water is supplied from the water heater to both the outgoing pipe and the return pipe, and the hot water is supplied to the inner and outer flow paths A and B of the adapter main body, the first and second flow paths 43a and 43b, the first. And it passes through the 2nd electric power generation chambers 7a and 7b, and is supplied in the bathtub from the outer side openings 64 and 64 of the 1st and 2nd electric power generation units 6a and 6b.

  Even during hot water pouring, the power is generated in each of the power generation chambers 7a and 7b, and the LED 46 is lit as described above.

  As described above, according to the hot-water supply adapter of the present embodiment, the LED 46 can be turned on by self-power generation when reheating or the like, and a predetermined effect effect by light can be given in the bathtub.

  Furthermore, since the hot water supply adapter according to the present embodiment is configured to generate electric power using a piezoelectric element, that is, the electric power generation includes a casing 60 in which a part of the inner wall is configured by the piezoelectric element, and a ball 69 that flows inside the casing 60. Since power is generated by the units 6a and 6b, the structure of the power generation unit can be simply completed, and the size can be reduced. In particular, the hot water supply adapter of the present embodiment can more reliably simplify the structure and reduce the size as compared with a case where a generator having a complicated structure and a large size is used.

  Moreover, in this embodiment, the water flow disturbance piece 66 is provided in the power generation units 6a and 6b so that the water flow in the units 6a and 6b is in a turbulent state, and the ball 69 flows irregularly by the water flow in the turbulent state. Thus, the piezoelectric element walls (front and rear walls 61 and 62) are made to collide even more vigorously. For this reason, a piezoelectric element can be operated more efficiently, sufficient electric power generation amount can be ensured more reliably, and LED46 can be lighted more reliably.

  Further, in the present embodiment, since the power generation units 6a and 6b are provided in both the forward flow path and the return flow path, a larger amount of power generation can be ensured and the LED 56 can emit light more reliably.

  In the present embodiment, since the mesh sheet 65 is disposed in the openings 63 and 64 at both ends of the power generation units 6a and 6b, the mesh sheet 69 prevents the balls 69 in the power generation units 6a and 6b from flowing out. On the other hand, it is possible to smoothly flow hot water into and out of the power generation units 6a and 6b without hindrance.

  In the present embodiment, the power generation units 6a and 6b are detachably attached to the flow path partition member 3, and the front walls (covers) 61 of the power generation units 6a and 6b are detachable. , 6b can be repaired by removing the power generation units 6a, 6b from the flow path partition member 3 and removing the cover (front wall 61), and repairing the interior of the power generation chambers 7a, 7b. Can be performed reliably. For example, when the mesh sheet 65 is clogged, the mesh sheet 65 can be easily taken out and reliably cleaned by removing the front wall 61 of the power generation units 6a and 6b. Thus, the maintenance inspection in the power generation chambers 7a and 7b can be performed simply by removing the front wall 61 of the power generation units 6a and 6b.

  Furthermore, in this embodiment, since the power generation units 6a and 6b are attached to the flow path partition member 3 externally, existing ones can be used as the flow path partition member 3 from the past. That is, the configuration of the present invention can be realized simply by attaching the power generation units 6a and 6b to an existing hot water supply adapter (existing flow path partition member).
