Abstract

<P>PROBLEM TO BE SOLVED: To provide a stream illuminating device which can illuminate a stream W flowing in a channel region 2a in a manner being luminous in every direction with respect to a cross section of the stream without directly exposing light of an illuminating section 3a of a light emitting means 3. <P>SOLUTION: The stream illuminating device is formed of a water channel 2 having a region 2c that exhibits stream appearance to the outside, the light emitting means 3 having the illuminating section 3a thereof faced to the inside of the water channel 2, and a bubble mixing means 4 for mixing a number of bubbles B into fluid W flowing in the water channel 2. According to the stream illuminating device, the stream which includes a number of bubbles mixed therein and allows light emitted from the illuminating section 3a to pass therein, flows in the region 2c that exhibits the stream appearance in the water channel 2. The light emitted from the light emitting section 3a directly illuminates the stream W flowing in the water channel 2, and therefore the light is not directly exposed to the outside of the region 2c that exhibits the appearance. Further, the light passing through the fluid W flowing in the region 2c that exhibits the appearance is irregularly reflected by a number of bubbles B mixed in the fluid W, and therefore the light leaks in every direction with respect to the cross section of the water stream 2 to the outside. <P>COPYRIGHT: (C)2006,JPO&NCIPI

(1) When irradiating light toward the external water discharge channel of the former device and the latter device, the irradiation region of the light emitting means and the region of the water discharge flow do not match when the external water discharge channel is viewed along the cross section. In some cases, the light from the light emitting means can be seen directly, or conversely, a portion where the water current does not shine may be generated, and the water flow may not be shined well. In the former device, since light is emitted from the outside of the external discharge channel toward the external discharge channel, it is difficult to irradiate only the external discharge channel so that only the discharge flow is shining. Only did not shine and did not look good. In the latter device, light is emitted toward the internal water discharge channel or light is emitted from the water discharge port toward the external water discharge channel, so that the light passing through the water discharge flow is smooth on the surface of the water discharge flow.

  The configuration other than the above differences is substantially the same as the inventive device 1 of the first embodiment shown in FIG. 2, and the inventive device 1 of the first embodiment among the reference numerals shown in FIG. The same reference numerals denote the same members and the like.

  The device 51 of the present invention can be configured to discharge water at an arbitrary angle between the horizontal direction and the hanging direction, in addition to the aspect of discharging water in the hanging direction. In this case, the portion 11a of the bubble injection nozzle 11 extending into the region 2c where the water flow can be seen is formed by a flexible tube, and flows through the water channel region 2c discharged at an arbitrary angle between the horizontal direction and the drooping direction. It is preferable that the tube is deformed into a curved shape by the force applied to the tube from the water flow W and is automatically positioned closer to the center of the water channel region 2c.

(Fifth embodiment)
FIG. 9 shows a fifth embodiment of the device of the present invention, which is a combination of a front view and a block diagram showing a cross section of the main part. The device 61 of the present invention according to the present embodiment is different from the device 1 of the present invention 1 of the first embodiment shown in FIG. 2 in that a region 2c extending from the discharge port 5a of the water discharger 5 and having a water flow appearance can be obtained. The irradiation part 3a (9b) of the light emitting means 3 is allowed to face the place where the water receiver 62 such as a basin intersects, and the irradiation part 3a is covered with the water flow W flowing through the water flow region 2c. This is to prevent the light emitted from the water from being directly visible from the outside of the water channel region 2c. The water channel region in which the light incident on the water flow from the irradiation part 3a of the light emitting means 3 and incident on the water flow is diffusely reflected by a large number of bubbles B mixed in the water flow by the bubble mixing means 4 so that the water flow can be seen. The light leaks out from the entire periphery of the cross section 2c and emits light. In the case of this example, the starting point of the range L where the water flow W shines is the irradiation unit 3a.

  The configuration other than the above differences is substantially the same as the inventive device 1 of the first embodiment shown in FIG. 1, and the inventive device 1 of the first embodiment among the reference numerals shown in FIG. The same reference numerals denote the same members and the like.

  Note that the device 61 of the present invention has a configuration other than the case where the direction of water discharge from the discharge port 5a is vertical, provided that the location where the region 2c where the water flow can be seen and the water receiver 62 intersect is constant (for example, a constant amount of water tap). It may be a case where the direction is diagonal.

(Sixth embodiment)
FIG. 10 shows a sixth embodiment of the apparatus of the present invention, which is a combination of a front view and a block diagram showing a cross section of the main part. The present invention device 71 according to the present embodiment is different from the present invention device 1 of the first embodiment shown in FIG. 1 in that the water channel region 2c can be extended from the discharge port 5a of the water discharger 5 and the water flow can be seen. Is formed inside the pipe 72 through which the plurality of bubble inlets 11b of the bubble mixing means 4 are opened at appropriate intervals along the water flow direction on the inner surface of the pipe 72. That is, the bubble B is introduced into the water channel region 2c from the bubble inlet 11b selected by the bubble inlet selection means 74 from 11b. The command signals a and b issued by the control circuit 14 are output to the bubble mixing means 4 selected by the bubble inlet selection means 74. As the cross-sectional shape of the pipe 72, a circle, an ellipse, a triangle, a square, or the like is selected.

  The configuration other than the above differences is substantially the same as the inventive device 1 of the first embodiment shown in FIG. 1, and the inventive device 1 of the first embodiment among the reference numerals shown in FIG. The same reference numerals denote the same members and the like.

  The bubble inlet 11 b has a shape that does not disturb the water flow W flowing inside the pipe 72. The shape along the extending direction of the pipe 72 may be an arbitrary shape such as a shape that bends in a zigzag manner via a bent portion or a spiral shape, in addition to a linear shape. In this case, the device 71 of the present invention forms a water outlet at the end of the pipe 72 or connects the end of the pipe 72 to a water outlet (not shown), and observes the light emitted from the pipe 72 having an arbitrary shape. Water can be discharged.

  The device 71 of the present invention has a bubble to the fluid W flowing through the water channel region 2c from the bubble inlet 11b (second from the top in the case shown) selected from the plurality of bubble inlets 11b by the bubble inlet selection means 74. By mixing B, light irradiated from the light emitting means 3 and passing through the fluid W is diffusely reflected by a large number of bubbles B existing downstream from the selected bubble inlet 11b and leaks outside. As a result, the device 71 of the present invention can change the position where the water flow W shines by selecting an arbitrary bubble inlet 11b.

(Seventh embodiment)
FIG. 11 shows a sixth embodiment of the apparatus of the present invention, which is a combination of a front view and a block diagram showing a cross section of the main part.

  The device 81 of the present invention according to the present embodiment includes a water flow path 2, a light emitting unit 3, a water amount adjusting unit 86, and a water amount determining unit 87. The water flow path 2 includes a region 2a formed inside the water discharger 5 such as a water faucet, a region 2b that becomes the water discharge port 5a established in the water discharger 5, and a water discharge region 2c that can discharge water freely from the water discharge port 5a. Thus, the region 2 a formed inside the water discharger 5 communicates with the water supply path 7 through the water amount adjusting means 86.

  In the same way as in the first embodiment, the light emitting means 3 irradiates the irradiation unit 3a so that the irradiation unit 3a faces the inside of the water channel 2 and covers the entire irradiation unit 3a with the water flow W flowing through the water channel 2. The light irradiated from the portion 3a toward the water flow path 2 is not directly visible from the outside of the water discharge region 2c where the water flow can be seen. The light emitting means 3 of the present example is formed of a lamp 8 made of LEDs or the like provided on the outside of the water discharger 5 and glass or a synthetic resin material, and the like, and from the outside of the water discharger 5 to the water channel region 2 a inside the water discharger 5. The light guide member 9 is inserted, and the light emitted from the lamp 8 is captured by the one end surface 9a of the light guide member 9 and irradiated from the other end surface 9b (irradiation unit 3a) toward the water channel region 2b (water outlet 5a). The irradiated light is incident on the water flow W, and the incident light passes through the water flow W flowing through the water discharge region 2c where the water flow can be seen. The lamp 8 may include three primary color flumps so as to emit light of a desired color by a combination of the lamps. The light emitting means 3 includes a power supply control circuit 21, and the power supply control circuit 21 controls the lighting time zone, illuminance, color, and the like of the lamp 8.

  The water amount adjusting means 86 includes a flow rate adjusting valve 86a and an operation portion 86b for operating the flow rate adjusting valve 86a, and the operation portion 86b operates the flow rate adjusting valve 86a to discharge the specified water discharge amount from the water outlet 5a. It is like that.

  The water amount determining means 87 sends a water discharge amount signal d corresponding to the designated light emission start position E to the operation portion 86b of the water amount adjusting means 86 based on the relationship between the light emission start position E (described later) of the water flow path 2 and the water discharge amount. It is designed to output. The relationship between the light emission start position E of the water flow path 2 and the amount of discharged water is determined based on the result of testing in advance. The water amount adjusting unit 86 that has received the signal d discharges the water discharge amount corresponding to the light emission start position E designated by the water amount determining unit 87.

  The water flow W discharged from the water discharge port 5a of the water discharger 5 has an upstream region (laminar flow region) Wa whose surface is smooth (laminar flow surface) and a downstream region whose surface is non-smooth (turbulent flow surface) ( Turbulent flow region) Wb is formed. The location where the upstream region (laminar flow region) Wa transitions to the downstream region (turbulent flow region) Wb (the location corresponding to the light emission start position E) varies depending on the amount of water discharged from the water outlet 5a. That is, the light that passes through the water flow W that flows through the water discharge region 2c that is irradiated from the light-emitting means 3 and can appear as the water flow continues to be totally reflected on the surface of the upstream region (laminar flow region) Wa where the surface of the water flow W is smooth. However, it does not leak to the outside, but leaks to the outside in the downstream region (turbulent flow region) Wb that becomes a non-smooth surface, and the water flow W is shined. As described above, in the upstream region Wa where the surface of the water flow W is smooth, light does not leak from the surface of the water flow. For this reason, the light emission start position E is a location where the upstream region (laminar flow region) Wa changes to the downstream region (turbulent region) Wb.

  In the present invention device 81 according to the present embodiment, when the designated light emission start position E is input to the water amount determining means 87, the water amount adjusting means 86 that has received an instruction from the water amount determining means 87 adjusts to the corresponding water discharge amount, Light is emitted by leaking light outward from the designated light emission start position E of the water flow W flowing through the water channel (water channel region where the water flow can be seen) 2c. Therefore, the device 81 of the present invention can specify the start position E where the water flow W flowing through the water discharge channel 2c shines.

The sound device 16 includes a sound source supply device 17 including a player that plays music tape, CD (compact disc), MD (mini disc), or a tuner that receives radio waves, and an amplifier 18 with a tone control circuit. And a speaker 19, and a sound source signal of the sound source supply device 17 is amplified by an amplifier 18 and is generated by the speaker 19.

  The interlocking unit 88 is configured to synchronize the sound change of the sound source supply device 17 with the change of the light emission start position E, and sound information emitted by the acoustic device 16 (for example, information on sound volume and sound quality related to frequency). The target value of the light emission start position E is determined based on the above. The control target value based on the content of the sound information is determined based on a predetermined rule. Upon receiving the target value instruction from the interlocking unit 88, the water amount determining unit 87 outputs a water discharge amount signal d corresponding to the target value to the water amount adjusting unit 86, and the water flow flowing through the water discharge channel (the water channel region 2c where the water flow can be seen). The light leaks outward from the light emission start position E of the target value of W and is emitted. In this way, the change in sound and the change in the light emission start position E of the water flow W can be linked to provide the user with a relaxation effect.

  In addition, the inventive device 81 according to the present embodiment links irradiation information (for example, information on illuminance, color, etc.) from the power supply control circuit 21 in order to link the change in irradiation and the change in the state in which the water flow W shines. ) To determine the target value of the light emission start position E. The control target value based on the content of the irradiation information is determined based on a predetermined rule. Upon receiving the target value instruction from the interlocking unit 88, the water amount determining unit 87 outputs a water discharge amount signal d corresponding to the target value to the water amount adjusting unit 86, and the water flow flowing through the water discharge channel (water channel region where the water flow can be seen) 2c. The light leaks outward from the light emission start position E of the target value of W and is emitted. In this way, the change in the irradiation of the light emitting means 3 and the change in the light emission start position E of the water flow W can be linked to give the user a relaxation effect.

  In addition, although this invention apparatus 81 is a thing of the aspect which discharges water in the drooping direction from the discharge outlet 5a, it is not limited to this, The thing of the aspect which discharges water at the arbitrary angles between the horizontal direction and the drooping direction, The thing of the aspect which discharges water diagonally upwards may be sufficient.
