Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquarium for appreciation fish and a fish breeding tank, and more particularly to an aquarium used together with a water purifying device.

[0002]

2. Description of the Related Art In a conventional water tank, as shown in FIG. 6, a water tank bottom chamber 21 is formed by a dividing member 20 having a large number of holes 19, and the bottom of the water tank bottom chamber 21 is provided at the bottom center. It has a structure having an inclination 23 facing the collection chamber 22 (Japanese Patent Laid-Open No. 292838).

In the above structure, contaminants such as fish excrement and uneaten bait pass through the hole 19 of the dividing member 20 into the water tank bottom chamber 21 and fall along the slope 23 into the collecting chamber 22. Most of the pollutants that have fallen into the collection chamber 22 flow out from the outlet 24 to the purification device section 25 together with the water flow.

[0004]

However, in the above-mentioned conventional aquarium for viewing, in the water in the aquarium, fish excrement and uneaten food are easily deposited on the bottom of the aquarium, and water quality such as generation of ammonia occurs. There were problems such as pollution and loss of aesthetics.

The present invention is intended to solve the above problems, and to easily discharge contaminants accumulated on the bottom of a water tank to the outside to maintain the aesthetics and water quality of the water tank without extensive cleaning of the water tank. To aim.

[0006]

In order to achieve the above-mentioned object, the present invention provides a plurality of outlets at the bottom of the aquarium main body and divides the aquarium into a fish breeding section and a contaminant collecting section by dividing members. It is configured such that it is divided and a contaminant guide means is disposed in the contaminant collecting section.

[0007]

According to the present invention, due to the above construction, contaminants such as fish excrement and uneaten bait pass through the holes of the dividing member and fall to the contaminant collecting section at the bottom of the water tank. The contaminants that have fallen into the contaminant collecting portion are collected in the hopper-like contaminant guide means provided corresponding to the plurality of outlets. When the number of days passes and the amount of contaminants accumulated in the contaminant guide means reaches a predetermined amount, the contaminants are discharged from the water tank together with the water flow by opening the valve connected to the discharge port.

[0008]

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

In FIGS. 1 to 3, reference numeral 1 denotes a water tank body having a plurality of discharge ports 2 at the bottom. 3 is a large number of water passages 4
Is a dividing member that divides the inside of the water tank into the fish breeding section 5 and the contaminant collecting section 6. Contaminant collection means 6 is provided with a contaminant guide means 7 for guiding contaminants to each of the outlets 2. One of the outlets 2 is a water purification device 9 via a solenoid valve 8.
Is connected to the inflow passage 10 to the other outlet 2
Connected to. A flow path opening / closing means 14 including an opening / closing valve 12 that can be opened / closed from the outside of the water tank and an opening / closing valve driving means 13 connected to the opening / closing valve 12 by a screw is attached to the discharge port 2 connected to the discharge path 11. ing. On-off valve 12
The on-off valve driving means 13 and the on-off valve driving means 13 are coupled by a screw so that they can be easily attached and detached. 15 is a flow path opening / closing means 14
Is the lid. The purifier 9 is connected to an outflow passage 16 for sending purified water to the aquarium 1.

FIG. 4 shows a flow state at the time of discharging pollutants,
F ₁ is the flow of contaminants from the guide means 7 toward the outlet 2. F ₂ is a flow from the discharge port 2 toward the discharge path 11.

In the above structure, when the water purifying device 9 is operated, the aquarium water passes through the water passage 4 of the dividing member 3 and enters the contaminant collecting portion 6. The aquarium water that has entered the pollutant trap 6 flows toward the discharge port 2 connected to the inflow path 10 while dropping the pollutant having a high specific gravity contained in the water into the hopper-like pollutant guide means 7. The aquarium water from which the pollutant having a large specific gravity has been removed further enters the purifying device 9 from the inflow passage 10, and the contaminant is decomposed and removed by the purifying means such as bio, and the outflow passage 16
Is returned to the aquarium 1.

When the amount accumulated in the contaminant guide means 7 reaches a set level (for example, the upper surface of the contaminant guide means 7), the open / close valve drive means 13 pushes the open / close valve 12 upward. When the open / close valve 12 is pushed upward, the accumulated contaminants flow out from the discharge port 2 due to the steep slope of the contaminant guide means 7 and the force of water flowing out. As a result, the bottom of the water tank 1 is cleaned almost as it was when the water tank was installed.

Although the on-off valve driving means 13 is manually driven in the embodiment, it can be automated by using a motor or a solenoid.

According to the above-described embodiment, when the on-off valve 12 is closed, the water level pressure of the water tank is applied, and the degree of sealing of the valve is increased. Figure 5
Shows another embodiment, and 17 is a manual valve which is the flow path opening / closing means 14 attached to the discharge port member 18.

Also in the above configuration, similar to the above embodiment,
When contaminants such as uneaten food and excrement of fish accumulate in the contaminant guide means 7 and reach the set level (for example, the upper surface of the contaminant guide means 7), the manual valve 17 is opened. As a result, the accumulated contaminants are discharged together with the water, and the bottom of the water tank is cleaned.

According to the construction of this embodiment, since the valve portion is attached to the outside of the water tank, the operation becomes easy.

[0017]

As described above, the appreciation fish tank of the present invention has the following effects. (1) The aquarium can be kept in a clean state without the large-scale work of taking out fish, aquatic plants, paving stones, etc. from the aquarium and cleaning the contaminants accumulated on the bottom of the aquarium. Moreover, the drainage operation at the time of water change is easy, and the water quality control becomes easy. (2) By closing the water passage of the dividing member above the contaminant guide means corresponding to the outlet communicating with the inflow passage into which the solenoid valve is inserted, or by closing the upper portion of the dividing member with ornaments such as stones and corals, The inflow of contaminants to the solenoid valve and the purification device is reduced, and the reliability of the equipment is improved. (3) Since there is a degree of freedom in the position of the outlet connected to the purification device, the restriction of landscape creation in the water tank can be removed, and the installation position of the purification device can be freely selected.
