Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage device which is installed at the upper part of an ornamental fish tank and is attached to the drainage part of the upper filter tank that filters the water pumped up from the ornamental fish tank by a filter and returns it to the ornamental fish tank again.

[0002]

[Prior art]

 An example of a conventional ornamental fish tank will be described with reference to FIG. In FIG. 4, 1 is a water tank, 2 is an upper filtration tank mounted on the upper part of the water tank 1, 3 is mounted on the upper part of the filtration tank 2, and water in the water tank 1 is sucked by a water absorption pipe 3a. Is a pump for returning to the inside of the filtration tank 2 through the drainage pipe 3b.

The filtration tank 2 is composed of a filtration chamber 2a in which a filtration filter 4 is housed, and a drainage chamber 2b in which water filtered in the filtration chamber 2a is supplied through a hole 2c _{1 of a} partition wall 2c. ing. A drainage pipe 5 for returning the filtered water into the water tank 1 is attached to the drainage chamber 2b.

In the conventional aquarium fish tank constructed as above, the dirty water in the tank 1 is pumped up into the filter tank 2 by the pump 3, and the water is filtered by the filter 4 in the filter tank 2. It is filtered and returned to the inside of the water tank 1 through the drainage pipe 5 which is partially submerged in the water tank 1, so that the inside of the water tank 1 is always kept clean.

[0005]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional aquarium fish tank, since the water filtered by the filtration filter 4 is directly returned to the inside of the water tank 1 through the drainage pipe 5 of the filtration tank 2, clean water is discharged from the inner edge of the drainage pipe 5. Without being transmitted, the water drops from the central portion of the drainage pipe 5 and vigorously falls. Therefore, the water directly drops on the water surface in the drainage pipe 5 to generate water noise, and when the water droplets directly drop on the water surface, There was a problem that bubbles were generated when they were entrained.

Further, fine dust that could not be sufficiently filtered in the filtration chamber 2 a or dust that directly entered the drainage chamber 2 b from the outside falls into the water tank 1 through the drain hole or the drain pipe 5, and the water tank 1 There was also the problem of polluting the water inside.

The present invention is intended to solve the above-mentioned problems, and an object thereof is to prevent generation of water noise due to drainage from a filter tank and also to prevent entrainment of air to prevent generation of bubbles. It is intended to provide a drainage device for an upper part of an ornamental fish tank which can prevent and further remove dust contained in water from the filter tank.

[0008]

[Means for Solving the Problems]

 The drainage device of the upper filtration tank for ornamental fish tank of the present invention is intended to solve the above-mentioned problems, and is installed on the upper portion of the ornamental fish tank, and the water pumped up from the ornamental fish tank is filtered by a filter. A tubular drainage device that can be attached to the drainage pipe of the upper filtration tank that returns to the ornamental fish tank again, wherein the drainage tool has a fine mesh whose outer peripheral portion is in contact with the inner peripheral surface of the drainage pipe. It is characterized in that it is provided in the state of hanging inside.

The drainage tool may be configured to be attachable to and detachable from the drainage pipe, or the drainage tool may include an inner pipe and an outer pipe, and a peripheral portion of the mesh may be disposed between the inner and outer pipes. You may make it pinch.

【Example】

 Hereinafter, the drainage tool for the upper filtration tank for the ornamental fish tank according to the present invention will be described with reference to FIGS. The same reference numerals as those in the conventional example described above indicate the same members, and the description thereof will be omitted. In this embodiment, a cylindrical projection 2d is formed so as to project in the drainage chamber 2b of the filtration tank 2. The drainage pipe 5 is fitted inside the cylindrical projection 2d. In this case, the lower part of the drainage pipe 5 is submerged below the water surface.

In FIG. 1, reference numeral 6 denotes a tubular drainage tool which is detachably attached to the outer periphery of the tubular projection 2d, and fine dust or dust passing directly into the drainage chamber 2b from the outside passes through the top surface of the drainage tool. A fine mesh 7 having a density enough to prevent the above-mentioned phenomenon is hung down and stretched so that the peripheral surface is in contact with the inner peripheral edge of the cylindrical projection 2d.

Further, in another embodiment shown in FIGS. 2 and 3, the drainage tool 6 is divided into two parts, an inner pipe 6a and an outer pipe 6b, and a space between the inner and outer pipes 6a and 6b. It is attached by sandwiching the peripheral edge of the mesh 7. Even in this case, the mesh 7 is stretched so that the peripheral surface is in contact with the inner peripheral edge of the cylindrical projection 2d.

In the thus configured drainage tool of the present invention, the purified water accumulated in the drainage chamber 2b enters the net 7 and oozes to the outside from the peripheral surface of the net 7. Since the peripheral surface of the net 7 is in contact with the cylindrical projection 2d, the leached purified water hangs down along the inner peripheral surface of the cylindrical projection 2d and falls from the inner peripheral surface of the drain pipe 5 to the water surface. To do. Therefore, since the water droplets do not drop directly on the water surface, no water noise is generated, and air is not entrained, so that no bubbles are generated.

Moreover, since the dust that cannot be filtered by the filter 4 and the dust that directly enters the drainage chamber 2b are removed by the net 7, the water supplied to the water tank 1 is only clean water. is there. On the other hand, when dust collects on the net 7, in the embodiment shown in FIG. 1, the net 7 can be washed by removing the drainage tool 6 from the cylindrical projection 2d. In this embodiment, the outer pipe 6b is separated from the inner pipe 6a, and the net 7 is taken out to perform cleaning.

In the above embodiment, the drainage tool 6 is detachably attached to the cylindrical projection 2d protruding from the bottom surface of the filtration tank 2, but only the hole is provided on the bottom surface of the filtration tank 2. Alternatively, the drainage pipe 5 may be fitted and fixed in this hole, and the drainage tool 6 may be detachably attached to the upper end of the drainage pipe 5.

[0016]

[Effect of device]

 According to the present invention, as described above, the drainage tool is attached to the drainage pipe attached to the filtration tank, and the drainage tool is stretched with a mesh so that the outer circumference is in contact with the inner peripheral surface of the drainage pipe. The clean water of the above is transmitted to the inner surface of the drainage pipe by the net and drops to the water surface. Therefore, the sound of falling water is not generated, and the generation of bubbles due to the entrainment of air can be prevented. Dust that cannot be completely filtered can be removed with a net.

Further, since the drainage tool to which the net is attached is detachable from the drainage pipe or the mesh is detachable from the drainage tool, even if dust is collected on the net, the drainage pipe is attached. It has the effect that the net can be easily removed and cleaning is easy.
