Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a fountain device having a structure in which at least one of a fountain and a fountain nozzle is illuminated using an optical fiber.

BACKGROUND OF THE INVENTION For lighting fountain devices, it is advantageous to use optical fibers in order to avoid the problem of electrical leakage and to obtain a unique decorative effect.

However, if the length of the optical fiber installed or the amount used increases, the transmission loss of the optical fiber increases significantly, and the installation work becomes labor-intensive. Furthermore, if a large number of optical fibers protrude over a long distance from the aquarium, there is also the problem that it spoils the aesthetic appearance.

(Problems to be solved by the invention) The invention was made in order to avoid the above-mentioned problems that may occur in the past. To provide a fountain device which is further compact and has an improved aesthetic appearance.

(Means for Solving the Problems) The present invention is characterized by a container-shaped base part, a water tank connected to the upper part of the base part, and a water tank disposed within the water tank. at least one nozzle device that sprays water; a transparent body that is fitted into at least one through hole formed in the bottom plate of the aquarium and closes the through hole; and a decoration extending from the bottom to the top of the transparent body. A light source provided within the base section to illuminate the light, and a plurality of light sources whose starting ends are attached to the bottom plate of the aquarium via fittings so as to receive the light radiated upward through the transparent body. an optical fiber, the end of each optical fiber is connected to the opening end of the nozzle so as to illuminate the vicinity of the opening end of the nozzle, the water sprayed from the nozzle, or the ornaments in the aquarium. In fountain devices attached to surroundings or ornaments.

(Function) The optical fiber extends over a short distance from the transparent body of the bottom plate of the aquarium to the nozzle device of the aquarium. The light emitted from the light source passes through the transparent body and enters the optical fiber, and then exits from the optical fiber to illuminate the nozzle device, the water emitted from it, or the decorations in the aquarium.

(Example) The present invention will be described below based on an example shown in FIGS. 1 to 3.

In each figure, the fountain device according to the present invention comprises a container-shaped base part 1 and a water tank 2 connected to the upper part of the base part 1. The base portion 1 and the water tank 2 are partitioned by a bottom plate 3 of the water tank 2. Note that the water tank 2 has a drain 2a.

At least one (six in this embodiment) nozzle device 4 is arranged in the water tank 2 to spray the water W therein. The nozzle arrangement 4 is of the desired existing type and has the required water pressure source upstream thereof.

At least one hole formed in the bottom plate 3 of the aquarium 2
A transparent body 5 such as a lens is fitted into each of the five (three in this embodiment) through holes 3a to seal the through holes. The transparent body 5 is made of acrylic glass, for example.

Further, in the base portion 1, the number of light sources 6 for irradiating decorative light from below to above through the transparent bodies 5 is provided in the same number as the transparent bodies 5. The light source 6 is made of an existing one such as a halogen lamp, for example.

On the other hand, in the water tank 2, a plurality of sets of optical fibers 7 that receive light irradiated upward through each transparent body 5 are arranged, and each set of optical fibers 7 exits the transparent body 5 from its starting end 7a side. The starting end 7a is attached to the bottom plate 3 of the aquarium 2 via a fitting 8 for receiving light. That is, the fixture 8 serves to bundle the starting ends of each optical fiber 7, and is fixed to the surface of the bottom plate 3 of the water tank 2 in a state surrounding the transparent body 5. The terminal ends 7b of each set of optical fibers 7 are attached around the nozzle portions 4a of several nozzle devices 4 so as to surround them, as shown in FIG. Each optical fiber 7 illuminates at least one of the corresponding nozzle portion 4a and the jetted water. However, the manner in which the optical fiber 7 is attached to the nozzle device 4 is arbitrary. Note that the optical fiber 7 may emit light only from the terminal end 7b, but the core material near the terminal end 7b may be exposed to illuminate the side surface of the nozzle portion 4a. Further, each optical fiber 7 may illuminate decorative items in the aquarium other than the nozzle.

In this embodiment, a desired number of speakers 9 are arranged within the base 1 in order to obtain acoustic effects.
Particularly in the case of a music-tuned fountain, its control (not shown) is also provided in the base part 1. The light source 6, speaker 9, control unit, etc. provided in the base part 1 are all placed on the slide plate 10, and the slide plate 10 is inserted into the base part from the through hole 11 on the side of the base part 1. By making it possible to take them in and out like a drawer into and out of 1, it becomes extremely easy to attach and detach them, replace them, maintain them, inspect them, etc. Note that these power cords and the power cable of the water pressure source are also drawn out through the through hole 11.

To explain the operation of the fountain device configured as described above, the nozzle device 4 blows up water in the water tank 2 as in the past, while the light source 6 sends decorative light to the optical fiber 7 through the transparent body 5. The decorative light illuminates the vicinity of the nozzle device 4, the fountain itself, or ornaments in the aquarium. Note that the transparent body 5 may be made of translucent colored glass in order to color the decorative light. Further, a translucent colored plate such as a colored lens may be provided between the light source 6 and the transparent body 5.

In this fountain device, since the optical fiber 7 extends over a short distance from the transparent body 5 to the nozzle device 4, there is little transmission loss of light and the effort required to install the optical fiber 7 is greatly reduced. Moreover, there is no waste in the length of the optical fiber 7 that projects upward from the water W in the water tank 2, and the aesthetic appearance is not spoiled.
Also, since the light source 6 is located outside the aquarium 2,
There is no risk of electrical leakage, and since it is provided in the base part 1 adjacent to the water tank 2, there is no need to require installation space elsewhere, making it possible to make the entire fountain device more compact.

Especially when the light source 6 is installed on the slide plate 10, it becomes extremely easy to take it in and out from the base part 1 as described above. Furthermore, in order to make inspection of the light source 6, etc. more convenient, a portion 3' of the bottom plate 3 of the water tank 2, which has the through hole 3a and the transparent body 5, is detachably separated from the main body of the water tank 2 like an inner lid. Good too. In this case, the bottom plate part 3' and the water tank 2
A packing 12 or the like is interposed between the main body and the main body. The shape of the bottom plate portion 3' is arbitrary. Similarly, the shape of the aquarium 2 can be circular, for example, fan-shaped, square, polygonal, etc.

Further, the heat generated from the light source 6 can be released to the outside through the through hole 11 or the like by using a fan or the like. Note that a water basin and ornaments can be placed on the bottom plate 3 inside the aquarium 2.

(Effect of the invention) As explained above, according to the invention, the base part,
Since the water tank, nozzle device, optical fiber, transparent body, and light source are integrated into a unit, the length of the optical fiber can be extremely shortened, reducing transmission loss and simplifying the installation work of the optical fiber. Since the fibers are not taken out to the outside, the aesthetic appearance is not spoiled, and the problem of electric leakage related to the light source can be avoided.
