Embodiments of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, the display device includes:
A water tank 11 in which water W mixed with an antiseptic is stored, and a water tank
Plural kinds of models 12 contained in water W in 11 and a tank
It comprises a water flow generator device 13 for generating a water flow in the water W in 11.

The water tank 11 comprises a peripheral wall 21 having a hexagonal horizontal cross section and a flat bottom wall 22 which are integrally molded of transparent plastic. The upper end of the peripheral wall 21 is covered with a plastic cover 23. A UV lamp 24 is attached to the lower surface of the cover 23. The lamp 24 enhances the display effect and prevents algae or the like from being generated in the aquarium 11. A part of the peripheral wall 21 near the lower end and the bottom wall 22 are fitted in a casing 25. An outlet 26 is provided in the central portion of the bottom wall 22 near one end. A pipe insertion hole 27 is provided in the center of the bottom wall 22.

The plurality of types of models 12 come in various sizes and shapes, but all are made to resemble the shape of a tropical fish or a goldfish. One of the models shown in FIG. 2 and FIG. 3 will be described. This is a substantially flat elliptical floating body 31 that occupies most of the entire model 12, and is fixedly embedded in a part of the outer periphery of the floating body 31. It consists of a weight 32. The floating body 31 is made of an independent rubber foaming resin having a specific gravity of about 0.6 and has water resistance. The outer surface of the floating body 31 is colored. Also, a model
The outer surface of the floating body 31 may be subjected to a treatment for improving the wettability so that air bubbles do not easily adhere to the outer surface of the floating body 12. If air bubbles are attached to the outer surface of the model 12, the buoyancy of the model 12 changes, which is not preferable. The weight 32 is made of lead. Referring to FIG. 3, the floating body 31
The center of gravity G is at the middle of the height, but there is a weight 32 at a position separated by a predetermined distance L downward from the center of gravity. This position corresponds to the center of the lower edge of the abdomen of the tropical fish represented by the model 12. The specific gravity of the entire model 12 is adjusted to 1 ± 0.002. If the specific gravity is 1.002, the sinking speed is about 5 cm / sec, and if the specific gravity is 0.998, the ascent rate is 5 cm / sec.
It will be about.

The water flow generator 13 includes a horizontal partition plate 41 provided in the water tank 11, a dome-shaped blowing member 42 provided at the center of the upper surface of the partition plate 41, and an inlet end with a water tank bottom wall 22. The circulation pipe 43 is communicated between the partition plates 41 and the outlet end is communicated between the partition plates 41 and the blowing member 42, and a pump 44 provided in the circulation pipe 43.

On the upper surface of the partition plate 41, pebbles, gravel, etc. 45 are spread. Referring to FIG. 4, the partition plate 41 has a plurality of suction ports 51, and also has non-suction port portions 52 and 53 in the central portion and the central portion near one end, which is directly above the outlet. Each of the plurality of suction ports 51 has a width of 1 to 2 mm.
It has a slit-like shape and is evenly distributed over almost the entire partition plate 41 except for the suction port-free portions 52 and 53.
An inlet 54 is provided in the central portion 52 having no suction port.
Further, referring to FIG. 5, the upper surface of the partition plate 41 is flush with the upper end surface of the casing 25. The blow-out member 42 has a plurality of blow-out ports 55 and is raised from the periphery so as to cover the inlet 54. The blowout ports 55 are round holes having a diameter of about 2 mm, and are evenly distributed over the blowout member 42. The inlet end of the circulation pipe 43 is connected to the outlet 26. The circulation pipe 43 is penetrated through the pipe insertion hole 27 near the outlet end, and the outlet end is connected to the inlet 54.

When the pump 44 is operated, the water above the partition plate 41 in the water tank 11 is sucked from the suction port 51 and is made to flow between the partition plate 41 and the water tank bottom wall 22 to be made to flow in. The water flows between the partition plate 41 and the bottom wall 22 of the water tank toward the outlet 26. The water flowing into the circulation pipe 43 from the outlet 26 is guided to the inlet 54 by the circulation pipe 43, and the partition plate 41 is introduced from the inlet 54.
And the blowout member 42, and is blown out from the blowout port 55. The water sucked into the suction port 51 forms a downward flow in the water tank 11, and the water blown out from the outlet 55 forms an upward flow with a horizontal flow in the water tank 11, and as a result, the entire water tank 11 inside. An almost uniform and complicated water flow is generated on the other hand, and on the other hand, there is also a stagnant part of the water flow, and the stagnant place itself moves.

The plurality of models 12 put in the water W move up, down, left and right along the water flow as if the raw fish swim around. When the model 12 came to a stagnant stream of water, it stood there, which looks like raw fish poking. When the stagnation disappears due to the movement of the water flow, the stationary model 12 moves again. These seem to be raw fish swimming around, especially in the distance observation.

When the operation of the pump is stopped, there is no water flow in the water tank 11. Then, due to the slight difference in specific gravity between the model 12 and the water W, the heavy model 12 sinks to the bottom of the water, and the light model 12 floats up to near the water surface.

[0020]

According to the present invention, when a water flow is generated in the aquarium, the model is moved by the generated water flow as if swimming in the water or flying in the air. Since the model can be moved as if swimming in the water or flying in the air on the generated water flow, a display device that is open and attractive as well as watching the real thing Provided.

Further, since the water in the water tank is sucked from almost the entire partition plate and discharged from almost the entire blowing member,
Since the model is not sucked into the suction port or blown off from the air outlet, the model does not stay in one place, and the model looks more real.
