DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dynamic fluid object, and more particularly, to the movement of a visualization medium moving in a showcase by causing a flow in a fluid filled in the showcase. That can be viewed.

[0002]

BACKGROUND OF THE INVENTION There are many cases where objects are arranged in the interior of a room or at the entrance hall of a building for interior decoration or space decoration for entertaining visitors. Such objects include static objects that do not move and dynamic objects that move.

[0003] Many of such dynamic objects are usually made of solid objects, and all or some of the components can be moved using a power source such as an electric motor. It is.

In addition, instead of the above-mentioned solid object,
As a dynamic object using a fluid, there is a fountain that changes the injection form of water in various ways.

[0005] Many of the former focus on the creation of solid objects, and the dynamic elements are rather secondary. In the case of performing a complicated movement, the structure becomes extremely complicated, and there is a problem that the manufacturing cost must increase. The latter focuses on the movement of water as a jet flying in the air, but has a problem that the equipment is inevitably large and the installation place is limited.

The present invention was conceived in view of such circumstances, and while taking in the fun that is seen when a fluid is dynamically moved, it can be compared without selecting a place. It is an object of the present invention to provide a dynamic fluid object which can be installed at extremely low cost.

[0007]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

[0008] That is, the dynamic fluid object provided by the present invention is a showcase in which a part or all of the side wall is transparent, a liquid filled in the showcase, and mixed in the liquid. A large number of visualization media having a specific gravity slightly larger than the liquid, a liquid ascending passage having an inlet at the bottom of the showcase and an outlet at the top, and falling toward the bottom of the showcase. A liquid-permeable guide member for collecting and guiding the visualization medium to the inlet of the liquid ascending passage, and disposed at the inlet of the liquid ascending passage in the axial direction toward the inside of the liquid ascending passage. And a driving means for applying a speed to the liquid collected from the bottom of the showcase and ejecting the liquid from the nozzle.

When water is used as the liquid, the specific gravity of the visualization medium is optimally in the range of 1.1 to 1.15 when the shape of the visualization medium is a sphere or a shape close thereto. It is. When the shape of the visualization medium is a thin plate, the visualization medium may be in the range of 1.1 to 1.5.

[0010] In a preferred embodiment, the liquid ascending passage may be a cylindrical body made of a transparent member arranged upright inside the showcase.

When the driving means is in the operating state, the liquid from the nozzle is jetted toward the inside of the liquid ascending passage at the inlet of the liquid ascending passage, whereby an upward liquid flow is introduced into the liquid ascending passage. It is formed. At this time, the visualization medium collected by the guide member at the lower entrance of the liquid ascending passage has a specific gravity slightly larger than the specific gravity of the liquid, and has a specific gravity relatively close to the specific gravity of the liquid. The liquid around the inlet is moved by the jet flow of the liquid from the nozzle so as to be sucked and introduced into the liquid ascending passage, and is raised in the liquid ascending passage together with the upward liquid flow. . The large number of visualization media thus discharged from the upper outlet of the liquid rise passage into the surrounding liquid in the showcase collides with the liquid surface and spreads radially, while exerting the effect of gravity and the liquid in the showcase. Gently descends on the downward flow that occurs at In this case, since the specific gravity of the visualization medium is close to the specific gravity of the liquid, it does not drop rapidly. The visualization medium reaching the bottom of the showcase is collected by the guide member, guided again to the inlet of the liquid rising passage, and thereafter repeats the above-described movement. The driving means may be operated continuously or intermittently.

If the liquid ascending passage is formed of a transparent member, a large number of visualization media rise relatively quickly in the liquid ascending passage and then slowly descend while spreading over the entire showcase. It can be observed from outside. By using, for example, a medium with various colors as the visualization medium, the behavior of the visualization medium as described above can entertain the observer's eyes, which can be called “underwater fireworks”.

[0013] In a preferred embodiment, a sub-portion for injecting a part of the liquid given the speed by the driving means in a horizontal direction and substantially tangentially to the outlet portion is provided at an upper outlet portion of the liquid ascending passage. Nozzles are arranged.

According to such a configuration, the swirling motion can be given to the liquid flowing out of the upper exit of the liquid ascending passage and descending in the showcase. The behavior of the chemical medium becomes more varied.

[0015] Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a schematic diagram showing a basic configuration of one embodiment of a dynamic fluid object 10 according to the present invention. As can be seen from FIG. 1, the dynamic fluid object 10 has an upright cylindrical showcase 20 in which part or all of the side walls are transparent, and has the same axis as the showcase 20 in the showcase 20. Liquid rising passage 30 having an inlet 31 at the bottom and an outlet 32 at the top, respectively,
At the inlet 31 of the nozzle, the nozzle 40 arranged in the axial direction toward the inside of the liquid ascending passage 30, that is, in the vertical direction, and the liquid collected from the bottom of the showcase 20 is given a speed to give a speed to the nozzle 40. And a driving means 50 for jetting.
0 is filled with the liquid W, and a large number of visualization media M having a specific gravity slightly larger than the liquid W are mixed in the liquid W.

In the vicinity of the bottom of the showcase 20, a liquid-permeable guide member for collecting the visualization medium M falling toward the bottom of the showcase 20 and guiding it to the inlet 31 of the liquid ascending passage 30. 60 are arranged. The liquid to be filled in the showcase 20 is preferably water. In this case, the specific gravity of the visualization medium M is 1.1 to 1.1.
The range of 1.15 achieves the behavior of the visualization medium M with the movement of the applied liquid in the showcase 20, and circulates the visualization medium M without inconvenience, as described later. Desirable above.

The nozzle 40 is connected to the showcase 20
The pipe 51 communicating with the nozzle 40 is connected to the discharge side 40 of a pump 53 via a first valve 52. On the other hand, a liquid recovery conduit 54 that communicates with the bottom wall 21 of the showcase 20 is connected to the suction side of the pump 53. Further, a portion of the discharge-side pipe 51 closer to the pump than the first valve 52 and an intermediate portion of the liquid recovery pipe 51 are connected by a bypass pipe 55. A second valve 56 for adjusting the flow rate is provided at an intermediate portion of the passage 55. In the present embodiment, the pipe 51, the liquid recovery pipe 54, the first valve 52, the second valve 56, the bypass pipe 55, and the pump 53 constitute the driving means 50.

More specifically, the guide member 60 is
A receiving portion 61 disposed so that the nozzle 40 penetrates in the vertical direction, and a predetermined gap from the lower end inlet portion 31 of the liquid rising passage 30 formed of the cylindrical body; And an inclined guide portion 62 extending in a hopper shape from the periphery to reach the inner wall of the showcase 20. As shown in FIG. 2, the through hole 63 is formed in the inclined guide portion 62.
A net member 64 is provided.

In the present embodiment, the showcase 20
A lighting lamp 71 is provided on the upper part of the display case 20, and several lighting lamps 72 for irradiating light obliquely upward are arranged around the lower part of the showcase 20. Each lighting 7
1, 72, pump 53, and first and second valves 5
2 and 56 are controlled by the control device 80 in a predetermined manner.

As can be seen from FIG. 1, the liquid basically circulates in the following route. That is, the liquid ejected from the nozzle 40 by the drive of the pump 53 rises in the liquid ascending passage 30 while drawing the liquid near the lower inlet portion 31 of the liquid ascending passage 30. The liquid that has exited from the upper outlet 32 of the liquid ascending passage 30 collides with the liquid surface and spreads around and descends outside the liquid ascending passage 30 in the showcase 20. Thus, a part of the liquid descending in the showcase 20 is supplied to the liquid ascending passage 3 as described above.
The liquid is again drawn into the liquid ascending passage 30 from the lower inlet portion 31 of FIG. 0, and the other passes through the mesh member 64 provided in the guide member 60 to reach the bottom of the showcase 20 or via the liquid recovery pipe 54. To pump 53.

In response to the movement of the liquid in the showcase 20, the plurality of visualization media M mixed in the liquid show the following behavior.

As described above, the specific gravity of the visualization medium M is slightly larger than the specific gravity of water. Therefore, when the pump 53 is stopped and the liquid in the showcase 20 does not move, the gravity is not changed. Is collected on the guide member 60. More specifically, the visualization medium M that has descended in the showcase 20 and reached the inclined guide portion 62 of the guide member 60 rolls up and down, so that the tray portion at the center of the guide member 60 is placed. Collected in 61. In addition,
The specific gravity of the visualization medium is preferably 1.1 to 1.15 when the shape of the medium is a sphere or a shape close to a sphere.
The range may be 1 to 1.5.

When the pump 53 starts operating, the nozzle 40
When the liquid is ejected from the liquid ejection passage 30, the visualization medium M on the guide member 60 is moved by the movement of the liquid entering the lower end inlet portion 31 of the liquid ascending passage 30 so as to be attracted by the liquid ejection. The inside can be raised rapidly. The visualization medium M that has exited from the outlet 32 of the liquid ascending passage 30 spreads over the entire cross section of the showcase 20, and has an annular space defined by the inner wall of the showcase 20 and the outer wall of the liquid ascending passage 30. Descend slowly. Also in this case, as described above, the specific gravity of the visualization medium M is close to the specific gravity of water, which is a liquid, and does not drop rapidly. Then, the visualization medium M reaching the bottom of the showcase 20 is collected by the guide member 60 as described above, and
The behavior of being sucked by the jet flow from 0 and being introduced into the inlet portion 31 of the liquid ascending passage 30 and rising is repeated.

In the present embodiment, the ejection of the liquid from the nozzle 40 can be controlled as follows. By adjusting the throttle amount of the second valve 56 for adjusting the flow rate, the flow rate of the water jetted from the nozzle 40 is adjusted. By opening and closing the first valve 52,
The ejection of the liquid from the nozzle 40 can be turned on and off.
That is, according to such a configuration, even when the pump 53 is continuously operated, the liquid ejection from the nozzle 40 can be turned on and off only by opening and closing the first valve 52. Even if the first valve 52 is in the closed state,
This is because the liquid from the discharge section of the pump 53 can circulate through the bypass pipe 55.

The visualization medium M may be a resin ball of various colors or a plate-like material of various shapes made of resin, and various sizes are selected. be able to. As described above, the behavior of the visualization medium M is such that both the showcase 20 and the liquid ascending passage 30 are configured as transparent cylindrical bodies, so that the center of the showcase 20 can be moved at once along its axis. After that, it spreads radially at the top of the showcase and then descends slowly, as if it were "underwater fireworks", and this behavior makes the eyes of the observer entertain. The liquid ejection from the nozzle 40 may be continuous or intermittent. Further, the behavior of the visualization medium M can be further varied by combining the continuous operation for a fixed time and the intermittent operation. Further, in the present embodiment, the illumination lamps 71 and 72 are arranged around the top and the lower part of the showcase 20, respectively.
By giving a change to the color or blinking state of the illumination, it is possible to make the movement of the visualization medium M look more varied.
