Regarding the method .
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a fountain device that can eject polka dots from a nozzle is known (see, for example, JP-A-9-141157). This water fountain device includes vibration applying means including a vibrator for applying vibration to running water, and a nozzle provided at the tip of the water flow pipe, and polka dots are ejected from the tip of the nozzle by the vibration of the vibration applying means. It can be made to.
[0003]
However, even if the polka dots generated by the fountain device are physically generated, they cannot normally be visually observed. Therefore, in order to appreciate the manner in which the polka dots fall, a strobe is placed at a position distant from the fountain device, the strobe is blinked at a predetermined frequency, and the polka dot is utilized using the afterimage effect of the human eye by the blinking light. Need to be visually observed.
[0004]
[Problems to be solved by the invention]
However, when such a strobe is used, field work is required at the introduction destination of the fountain apparatus, and there is a disadvantage that skill is required for construction. That is, not only is the equipment very large and expensive, but this is also a factor that cannot be adapted for a general-purpose type of viewing that has been downsized. In addition, the flashing light of the strobe gives a feeling of fatigue to human eyes, and even after viewing the fountain device, the eyes flicker and become congested.
[0005]
In order to eliminate such an inconvenience, the present inventor conducted an experiment by using a light emitting diode (LED) as another light source without using a strobe and blinking in the same manner as the strobe. However, in this case, only the polka dots falling just near the light emitting region of the light emitting diode can only be seen, and the polka dots over a series of positions up to the position where the polka dots ejected from the nozzle fall cannot be seen.
[0006]
Therefore, theoretically, it is sufficient to arrange a large number of light emitting diodes along the region from the ejection position of the polka dots to the falling position, but in this case, the number of light emitting diodes to be used becomes very large. Inconvenience. In addition, when the number of light emitting diodes is very large, the cost burden becomes heavy, and it takes time for the assembly process, and it is difficult to give a state that is easy for human eyes. Naturally, there are limitations.
[0007]
Therefore, the present inventor conducted various experiments, and visually observed a series of situations in which the polka dots dropped by spreading the flashing light of the light emitting diodes in a plane without extremely increasing the number of light emitting diodes. I found out that I can do it.
[0008]
The present invention has been devised based on the results of various experiments triggered by the inconveniences described above, and the purpose thereof is to allow visual observation from the position where the polka dots are ejected to the position where it falls without using a strobe. To provide a polka dot appreciation device and a polka dot appreciation method .
[0009]
Another object of the present invention is to provide a general-purpose polka dot appreciation device that can be mass-produced in a factory without requiring on-site construction.
[0010]
[Means for Solving the Problems]

When a predetermined power supply is turned on and the pump P is operated, water stored in the punching board 49 and below is sent to the aspirated tank 53 and continuously ejected from the nozzle 11 through the hose 55. Here, when the vibrator 60 is turned on and vibration is applied to the vibration plate 58, vibration is transmitted to the water in the tank 53 in response to this vibration, and a portion where the vibration is dense propagates in the flowing water from the nozzle 11. When leaving, a polka dot W is generated.
[0030]
Here, when the light emitting diode 13 is blinked, the blinking light blinks in a state of being diffused over the entire light diffusion panels 14A and 14B. A mode in which the polka dots W fall on the parabola , that is, a mode in which the polka dots W fall along the vicinity of the light diffusing unit 14 mounted on the outside of the main body 12 can be visually observed with the light diffusing unit 14 as a background .
[0031]
The dropped polka dots W penetrate the mat 50 in the base 13 and return to the water storage part S through the holes of the punching board 49. Accordingly, by storing a certain amount of water in the water storage part S in advance. The polka dots W can be continuously generated while circulating them.

Therefore, according to such an embodiment, since the light emitting diode 13 and the light diffusing means 14 are employed as means for making the polka dots W visible, it is possible to visually observe the polka dots W from the generation position to the fall position. Become. In addition, since a multi-strobe is not employed, the conventional inconvenience that causes the eyes to flicker and become congested can be reliably solved. Further, since the light emitting diode 13 is located inside the light diffusion panels 14A and 14B, the light feels soft when viewed from the outside, and the eye fatigue can be avoided from this point.
[0033]

For example, this type of polka dot appreciation device 100 can be provided around an open-air bath or the like to exhibit a function as a lighting device, and can watch the polka dots W while being immersed in hot water. Although the detailed structure of the polka dot appreciation device 100 shown in FIG. 5 is omitted here, the liquid supply means, the vibration applying means and the controller shown in the above embodiment are provided on the bottom side. ing. Further, this type of polka dot appreciation device 100 can be configured to be able to suck in the hot water of the open-air bath described above via a hose (not shown).
[0034]
In addition, the water in each of the above embodiments may be colored other than colorless, so that polka dots W having different aesthetics can be appreciated. Furthermore, although the light emitting diode 13 is disposed inside the light diffusion panels 14A and 14B, it can also be disposed outside these. The light emitting diodes 13 are arranged in two upper and lower rows, but can be increased or decreased depending on the height of the main bodies 12 and 102.
[0035]
Furthermore, the nozzle 11 is arranged to eject the polka dots W from the outer periphery of the main bodies 12 and 102 substantially in the radial direction. However, the present invention is not limited to this, and the main bodies 12 and 102 are arranged in a vertical plane. In the case of a planar structure located at, the nozzles 11 can be linearly arranged on top of the main bodies 12 and 102, and the polka dots W can be dropped so as to be arranged like a waterfall.

Further, the main body 12 is not limited to the configuration divided into three in the vertical direction, but can be changed to an integrally molded product, a two-divided configuration, or the like. That is, when the height of the main body 12 is further smaller than that of the above-described embodiment, it may be an integrally molded product or a two-divided type. In short, what is necessary is just to determine the division | segmentation number of the cylinder which comprises this according to the height of the main body 12. FIG.
[0039]
Further, in the above embodiment, the case where the polka dot apparel apparatus 10 is connected to a commercial power source to operate is described.
