Abstract

PROBLEM TO BE SOLVED: To cancel the problems of easily affecting the temperature of water in a water tank with an environmental temperature, frequently operating a device for warming or cooling, consuming much power, additionally, quickening the damage or wearing of device for warming or cooling to be frequently operated and severely loading the maintenance or check of equipment in management in spite of one glass or synthetic resin plate used for the transparent glass or synthetic resin surface of water tank for appreciation or observation. SOLUTION: A double layer body structure sealing gas into the transparent glass or synthetic resin of water tank is used and at the whole section except for the transparent glass or synthetic resin or its one part, a body structure sealing gas or heat insulating solid is used.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating structure for a water tank, and more particularly to an improvement in the heat insulating structure suitable for controlling the water temperature of a water tank mainly used for ornamental use.

[0002]

2. Description of the Related Art In general, a water tank mainly used for ornamental use has a front surface or a front surface and left and right side surfaces made of transparent glass or synthetic resin in many cases. Further, there is also a type in which the upper surface is formed of a transparent member from the viewpoint of lighting and maintenance of the water tank. Such aquariums are usually used for raising tropical fish.
It is often used for appreciation and pays great attention to water quality management and water temperature management.

One example of a conventional aquarium structure is as follows. The front and side surfaces are made of a single piece of glass to provide a wide field of view, and the back surface is made of a dark color such as black so that the color and shape of the reared fish can be easily observed. It has a light color such as pale blue or a mirror surface. Many upper surfaces are made of glass so that they can be observed from above. By mounting the filtration device on the top of the water tank with such a configuration, incorporating it on the bottom, or incorporating it on the back,
The breeding water in the aquarium is circulated to maintain the water quality.

[0004] Regarding the management of the water temperature, the temperature is increased by heating in the winter, spring and autumn seasons, but in summer, the water temperature may be too high, so that a cooling device is often incorporated. Particularly in recent years, tropical fish tanks have been increasingly installed in corporate offices and stores as well as in offices and stores for environmental beautification, and water temperature management has been emphasized since they are installed in heating and cooling environments. ing.

[0005]

In the conventional water tank, the surface of transparent glass or synthetic resin for observation or ornamental use is a single sheet of glass or synthetic resin. Temperature easily depends on the temperature of the environment,
Heating and cooling devices were frequently activated, wasting power. In addition, the frequently used heating and cooling devices are quickly damaged or worn, and the maintenance and inspection of the devices has become a large administrative burden.

[0006]

In view of the above situation,
In the present invention, a structure in which a gas or a heat-insulating solid is sealed in all or a part of a portion other than the transparent glass or the synthetic resin is used by using a two-layer structure in which a gas is sealed in a transparent glass or a synthetic resin. To use.

DETAILED DESCRIPTION OF THE INVENTION The object of the present invention applies to relatively small aquariums, which are mainly used for ornamental purposes. The front surface of this type of water tank, which normally corresponds to the front surface, is made of a double-layer glass having a heat insulating effect. In the case of a water tank of which the front and side surfaces are transparent in order to widen the field of view, the front and side surfaces are made of double-layer glass. If the upper surface is made of a transparent member for feeding or the like, the upper surface is also made of double-layer glass. Of the surfaces other than the surface composed of the double-layer glass,
At least one surface, preferably at least the surface excluding the bottom surface, is made of a heat-insulating member.

The glass is not limited to glass as long as it has the same transparency as glass, and a synthetic resin such as an acrylic resin can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the illustrated embodiments. 1 to 3 are external perspective views of a general ornamental aquarium, and include a front surface 1, a right side surface 2, a left side surface 3, a back surface 4, a top surface 5, and a bottom surface 6; At least the front surface 1, preferably the front surface 1 and the left and right side surfaces 2, 3 of the left and right side surfaces 2, 3 and the upper surface 5 are made of a transparent member such as glass or acrylic resin. More preferably, in addition to the above, the upper surface 5 that opens and closes for feeding is also formed of a transparent member.

FIG. 4 is a horizontal sectional view of the water tank of FIG. 1 in which the present invention is applied. The transparent member 10 such as glass or acrylic has a two-layer structure, and a gas such as air is sealed between the layers 11. It is. Reference numeral 12 denotes a sealing body for sealing the enclosed gas, and is in close contact with the two-layer transparent member 10. Seal 1
2 also has a function of maintaining the interval between the two layers of the transparent member 10.

The housing 13 other than the transparent member 10 constitutes the back surface 4, the bottom surface 6 and the upper surface 5, and is made of synthetic resin, metal or wood material in which a heat insulating material 15 such as gas or foam resin is enclosed. Etc. Although not shown, these back 4
In some cases, a filtering device or a water temperature adjusting device is incorporated in the bottom surface 6 and the shape is appropriately changed.

The sealing body 12 closely contacting the transparent member 10
It is not always necessary to have a function of sealing gas, and any function can be applied as long as it has a function of maintaining the interval between the transparent members 10. That is, since the transparent member 10 is surrounded by the housing 13 at the stage of being incorporated into the water tank, the transparent member 10 is substantially
The gas inside hardly enters or exits the outside, and the heat insulating action can be almost achieved. However, in order to expect the intrusion of dust and a reliable heat insulating effect, it is preferable that the sealing body 12 be in close contact with the transparent member 10 and seal the gas between the layers 11 as described above.

The upper surface 5 is provided with a feed port 14 separately from the transparent member 10 as shown in FIG. 1, and as a feed port 14 by lifting the entire transparent member 10 as shown in FIG. The configuration shown in FIG. 1 is effective in consideration of a reduction in the heat insulation effect due to opening and closing, breakage due to careless operation, and the like. FIG. 5 shows a cross section at the position of the transparent member 10. FIG. 6 shows a cross section of the feed port 14.

As described above, since the change in the water temperature of the ornamental water tank can be suppressed as small as possible, the operation of the heating device and the cooling device can be reduced, and the management cost can be greatly reduced. In addition, the stable condition of the water temperature allows the bred fish to have a stable health condition and be bred for a long period of time. In addition, even if an unexpected power outage occurs, the entire aquarium has an adiabatic structure, so it can maintain a stable water temperature for a much longer time than conventional aquariums, so the worst case of killing bred fish due to a power outage The situation can be avoided.
