Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquarium for accommodating and viewing tropical fish and the like.

[0002]

2. Description of the Related Art Conventionally, transparent aquariums have been used to keep ornamental fish such as goldfish, but in recent years, aquariums where tropical fish or the like are released for appreciation instead of goldfish are used by people such as the front of a building. It is often used for decoration in places with a lot of traffic. As the shape of this water tank, a rectangular one having an appropriate height is generally used.

[0003]

However, these aquariums give a feeling of having a small volume when the sides are opaque even if the front or front and rear surfaces are transparent glass plates or acrylic plates. If the four sides, including the side faces, are transparent, there are usually frames at the four corners, so the impression seen from the front and from the side was different.

Also, the top part which is the lid is separated from the aquarium and is to be removed by hand. Since the lamphouse for lighting is generally installed, it is located near the aquarium at the time of removal. I needed a place to put it in.

In view of this, the present invention does not particularly increase the amount of water in the water tank, and even if there is an opaque wall on both sides, this wall is not visible when looking into the water tank from the outside. The purpose of the present invention is to provide a water tank that makes you feel a large space.

[0006]

In order to achieve the above object, the present invention is characterized in that it has a top portion and a bottom surface, and at least one surface which is erected is made of a transparent curved plate.

Further, in the above structure, the top portion is composed of a pair of left and right lid plates, and the lid plates can be opened and closed left and right by hinges at the ends, and a light, a fan and the like are provided on the back side thereof. Further, a water ejection port is provided at the central portion of the bottom surface and a suction port is provided at the end portion so that the water in the water tank is always kept in a constant flow state.

[0008]

According to the above construction, since at least one surface of the water tank is made of a transparent curved plate, even if there are opaque walls on both sides, the water tank itself has the function of a convex lens, so the walls are hard to see. Become. Further, since the top part has a flat top surface, it can be rotated from the center to the left and right without removing it from the water tank when inspecting lights and fans in the water tank.

Further, in the case where the water spouting port is provided at the central part and the suction port is provided at the end part, the water can be circulated smoothly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings.

FIG. 1 shows an external perspective view of the front side of a water tank 1 according to the present invention. In this embodiment, the front surface is transparent and is constituted by a curved plate 2 having an appropriate height. This aquarium 1 is placed on a table 3 provided at a lower portion and has a required height, and a ceiling part which is a ceiling is composed of a pair of left and right flat lid plates 4 and 4. 4 is configured to be openable and closable with its end portion as a fulcrum. And both sides are wall boards 5
The rear surface is partitioned by a flat plate.

FIG. 2 shows another embodiment of the present invention.
The difference from FIG. 1 is that the rear surface of FIG. 1 is a flat plate,
The point is that the curved plate 2 is the same as the front surface.

FIG. 3 is a perspective view of only the portion of the water tank 1'with the top portion removed in FIG. 2. The top surface 2a and the bottom surface 2b are, for example, a transparent acrylic plate having a thickness of 10 mm, and the front and rear curved plates 2 are It is composed of a transparent acrylic plate having a thickness of 5 mm. In this embodiment, the upper surface 2a has two large holes 6 and 6.

The features of the embodiment shown in FIGS. 1 and 2 are as follows.

1) For example, the radius of curvature of the curved plate 2 is 1 m ± 1
When it is 0 cm, the inner surfaces of the wall plates 5 on both sides are hard to see, and the whole thing in the water tank is easy to see.

2) Since the water pressure is evenly applied by using the curved plate 2, the thickness of the acrylic plate can be made thin relative to the amount of water filled.

3) The interior looks large compared to the actual size, and the occupied space seems small.

FIG. 4 shows a state in which the lid plates 4 and 4 provided on the water tank 1 so as to be opened and closed by hinges 7 are opened from the center to the left and right, and on the back side of the lid plates 4 and 4, for example, one or both of them are fluorescent. A lamp 8 and a fan 9 are installed. In this case, the installation position of the cover plate 4 is set to a position of, for example, about 80 mm from the water surface of the water tank 1, and the fluorescent lamp 8 and the fan 9 are not wet with water.

Further, on the upper surface of the cover plate 4, there are provided a gap 10 for jetting light and air from the rear surface and a hole 11 for housing, respectively.

As a result, the upper surface of the water tank 1 is always flat, and when inspecting the fluorescent lamp 8 and the fan 9,
Maintenance can be easily performed by opening the lid plates 4 and 4 to the left and right with the hinge 7 as a fulcrum. At that time, since the lid plate 4 only rotates outward, no new storage space is required. Further, when the top part 4 is set, the fluorescent lamp 8 and the fan 9
The presence of the lamp house, which is equipped with, is not felt.

The fan 9 has a function of removing the heat of vaporization inside the water tank 1 to cool it, as shown in FIG.

FIG. 6 shows a front view in vertical section of the water tank 1 and the table 3. The bottom surface 2b has a water spouting port 12 in the center.
Water suction ports 13 are provided at both ends.

The water outlet 12 is connected by a pipe 16 to the outlet of a pump 15 driven by a motor 14 provided inside the table 3. Pump 15 is purification cylinder 2
4, a biological filter 17 for decomposing impurities in water by microorganisms, a UV lamp 18 for sterilization, and a heater 19 for water temperature adjustment are built-in. The water temperature is always 30 ° C. or lower and is usually kept at about 28 ° C.

The suction ports 13 and 13 are connected to each other by pipes 20 and 20 inside the base 3, respectively.
It is integrated with 20 by a T-shaped joint 21 provided at the butting portion. Then, the other one connection port of the T-shaped joint 21 is connected to the suction port of the purification tube 24 by a pipe 22. Further, inside the T-shaped joint 21, a heater sensor 23 for detecting the temperature of water entering the water tank is provided.

Therefore, the water in the water tank 1 sucked through the water suction port 13 provided on the bottom surface 2b is detected in temperature before it enters the pump 15 and is adjusted to an appropriate temperature in the purification tube 24 by the temperature adjustment to be sterilized. After that, it is filtered by the biological filter 17, and reaches the outlet 12 from the discharge port of the pump 15 to the bottom surface 2b of the water tank 1 by driving the motor 14.

Then, after circulating convectively in the water tank 1, it flows toward the suction port 13. For this reason, the flow in the water tank 1 becomes extremely good, and the water is constantly stirred so that no stagnation occurs. FIG. 7 is a perspective view (a) and a plan view (b) showing a flow state of water in the water tank.

[0027]

As described above, according to the present invention, since the shape of the water tank is at least one transparent curved plate, even if there are walls on both sides due to the convex lens effect, they cannot be seen and both sides are infinite. It spreads out and the depth of the aquarium spreads.

Further, since the top part is flattened integrally with the water tank, the appearance is improved and the water tank need only be opened and closed for inspection.

Further, by providing a jet port and a suction port on the bottom surface of the water tank to stir the water, it is possible to eliminate the occurrence of stagnation in the water tank.
