2. Description of the Related Art In a conventional integrated aquarium fish tank, the inside of the tank body is divided into a filter tank and a breeding tank by a partition wall material, a filter medium is loaded in the filter tank, and a pump is provided. A water inlet is provided in the wall material, and the water in the breeding tank that has passed through the water inlet flows to the suction port of the pump.

In an ornamental fish tank having such a configuration,
There is a flow of water being sucked around the water intake, but ordinary tropical fish and the like have sufficient exercise ability and can swim against the flow near the water intake, so there is no problem.

[0004]

However, as represented by jellyfish, creatures with poor athletic ability only float, and when bred in a conventional aquarium for aquarium fish, they tend to be near the water inlet to the pump. Because they cannot swim against the flow of water that is occurring in the water, they may be sucked into the water intake or left stuck and die.

[0005] When jellyfish are bred in an aquarium fish tank employing bottom filtration, the jellyfish may come into direct contact with the filtration material on the bottom and be damaged, resulting in death.

Accordingly, the present invention provides an aquarium fish tank which can prevent jellyfish or the like having poor athletic ability from being sucked into the water inlet or being damaged by direct contact with the filter medium, and which can be floated in a water stream. The purpose is to:

[0012]

Embodiments of the present invention will be described below with reference to the drawings. The ornamental fish tank 1 shown in the drawings is a so-called integrated tank in which a filtration tank is integrated with the tank main body 2,
Aquarium body 2 whose front and left and right sides are made of transparent plate
By providing the partition wall material 3 therein, the inside is partitioned into a filtration tank unit 4 on the back side and a rearing tank 5 on the front side, and a filter medium (not shown) such as a glass fiber lump in the filtration tank unit 4. And a submersible pump 6 is provided, and a gravel 7 is laid as a filtering material in the rearing tank 5 so that bottom filtration can be performed.

First, the filtration tank section 4 will be described in detail. A pump chamber 11 partitioned by a vertical partition plate 10 is formed on one side of the filtration tank section 4, and a shelf-shaped pump base 12 having an opening is provided below the pump chamber 11. The submersible pump 6 is mounted thereon, and the suction port 13 protruding from the lower part of the submersible pump 6 is inserted into the opening of the pump base 12. Then, the lower end inlet of the vertical pipe 15 is connected to the discharge port 14 opened on the upper surface of the submersible pump 6, and the shower pipe 17 is connected to the first horizontal opening of the branch pipe 16 attached to the upper end of the vertical pipe 15 in a substantially horizontal direction. And connecting the shower pipe 17 to the second horizontal opening of the branch pipe 16 in a substantially horizontal direction by passing the shower pipe 17 above the partition plate 10 and extending above the filtration chamber 4 ′. The connecting pipe 1 extends toward the rearing tub 5 through the upper end notch 19 of the partition wall material 3 with the 18 facing forward.
A vertical pipe 20 is connected to the distal end of the pipe 8 via a downward elbow, and two pipes are piped to the lower end of the vertical pipe 20 via a branch pipe 21 in a substantially L-shape. The L-shaped pipe will be described later.

In the filtration chamber 4 ′ divided by the partition plate 10,
The filter medium support base 2 is located at a position higher than the upper end edge of the vertical slit-shaped water inlet 25 formed on one lower side of the partition wall material 3.
6 and the space above the filter medium support base 26 is filled with a filter medium such as a glass fiber mass. The filter medium support base 26 is a water-permeable shelf-like plate having a number of small holes, and the space below this is communicated with the inside of the breeding tub 5 through the water inlet 25. It also communicates with the space below the pump base 12. Therefore, the space below the filter support base 26 functions as a flow path for the water in the breeding tub 5 flowing from the water inlet 25 to flow to the suction port 13 of the submersible pump 6, and flows down in the filtration chamber 4 '. The water filtered by the glass fiber mass or the like is supplied to the suction port 13 of the submersible pump 6.
It also functions as a flow path for flowing through. The filtering material in the filtering chamber 4 'performs not only physical filtration using a glass fiber lump or the like but also biological filtration using bacteria or the like.

Next, the rearing tank 5 will be described in detail.
In the present embodiment, since the bottom filtration is performed, the first water-permeable plate-like member 31 is provided on the bottom surface of the water tank main body 2 in a state where a space for the water-collecting channel 30 is provided. Is laid with gravel 7 as a filter medium, and a second
The breeding area 33 is provided above the second permeable plate member 32 by providing the permeable plate member 32.

The first water-permeable plate-like member 31 is a small slab-shaped plate member serving as the bottom of the breeding tub 5 and having a small slit-like hole 34 through which water is passed but the gravel 7 is not passed. Are installed at the same height as the pump base 12. Then, the first water-permeable plate-like member 31
The space below serves as a water collecting channel 30 through which filtered water passes between the gravel 7 and communicates with a suction port 13 opened below the pump base 12. Therefore, the water in the water collecting channel 30 is supplied to the suction port 13 of the submersible pump 6.
Sucked into.

The second water-permeable plate-like member 32 is provided on the filter material for bottom filtration and serves to partition the breeding area 33 from the filter material area. It is a board-shaped plate material having a large number of small holes 35 that cannot pass through, and has a downward projection 36 as a spacer on the lower surface.

The second water-permeable plate-like member 32
A pipe from the submersible pump 6 is disposed in the vicinity of the upper part of the pump.
Specifically, a branch pipe 21 is provided at the lower end of a vertical pipe 20 piped along a corner on the pump chamber 11 side in the breeding tub 5,
A first ejection pipe 4 is inserted into the first opening of the branch pipe 21 in the lateral direction.
0 in the substantially horizontal direction along the partition wall material 3, that is, the partition wall material 3
And a second squirting pipe 41 connected to a forward facing second opening of the branch pipe 21 so as to extend along the left side surface of the water tank main body 2. And the two first and second squirting pipes 40 and 41 have a substantially L shape along the bottom side edge of the breeding area 33. The first and second jetting pipes 40 and 41 have a large number of small jetting ports 42 and 43, respectively, which open upward in the longitudinal direction. That is, in the present embodiment, since the bottom filtration is performed, there is a filtration flow from the top to the bottom in the vicinity of the bottom of the breeding area 33, but the flow is blown upward to the opposite side to the flow direction. Install with outlets 42 and 43 facing.

The first jetting pipe 40 laid along the partition wall member 3 is provided with a water inlet 2 opening in the partition wall member 3.
5 has a sufficient length to pass in front of it, and also in front of the water inlet 25, the spout 42 opens upward.

Next, the operation of the ornamental fish tank 1 having the above-described configuration will be described with reference to an example in which jellyfish are bred. Some jellyfish can swim a little by shrinking their bulk, but most of them cannot swim and just float in the water.

When the submersible pump 6 is operated, the water sucked from the suction port 13 is discharged from the discharge port 14, and the discharged water is fed under pressure, rises in the vertical pipe 15 and rises in the branch pipe 16
One of them is jetted from the downward shower jet 44 through the shower pipe 17 and sprayed into the filtration chamber 4 ',
The other enters the breeding tank 5 through the connecting pipe 18 and descends in the vertical pipe 20. Then, it branches off at the branch pipe 21 at the lower end of the vertical pipe 20, and one flows inside the first ejection pipe 40 and the other flows inside the second ejection pipe 41.

The water that has passed through the first spouting pipe 40 is spouted upward from a spout 42 opened on the upper surface, rises along the partition wall material 3, reverses near the water surface and raises the breeding area 33.
The water that has not passed through the second water-permeable plate-shaped member 32 from the center or the front side of the water-repellent member rises again with the flow of the water jetted from the jet port 42. Therefore, the water that has passed through the first ejection pipe 40 becomes a circulating flow that rises along the partition wall material 3 and then descends.

Even if water is spouted upward from the spout 42, a second water-permeable plate member 32 to be described later
The flow of water descending toward the hole 35 is generated,
The flow directions of the two are completely reversed to offset the hydraulic power.
Therefore, even if a circulating flow is generated by the water jetted from the jet port 42, the flow velocity is extremely slow.

The water that has passed through the second jet pipe 41 jets upward from a jet port 43 opened on the upper surface, rises along the left side surface of the water tank main body 2, and turns upside down near the water surface to raise the breeding area 33. The water that has not passed through the second water-permeable plate-like member 32 and descends from the center to the right thereof rises again with the flow of the water jetted from the jet port 43. Therefore, the water that has passed through the second ejection pipe 41 becomes a circulating flow that rises along the left side surface and then descends, and the circulating flow is extremely gentle.

As described above, the first and second ejection pipes 40,
When the water that has passed through the inside 41 is jetted into the breeding area 33, it forms a gentle circulating flow, and the jellyfish in the breeding area 33 slowly floats in the breeding area 33 due to this circulating flow. Entertains the eyes.

Not all of the water in the breeding area 33 continues to circulate repeatedly, but a part of the water passes through the water inlet 25 of the partition wall material 3 by the suction action of the submersible pump 6, or The water passes through the hole 35 of the plate member 32 and is sucked into the suction port 13 of the submersible pump 6.

The water that has passed through the water inlet 25 of the partition wall material 3 joins the water filtered through the filter medium in the space below the filter medium support base 26, and is connected to the suction port 1 of the submersible pump 6.
Flow towards 3. In this way, when the water in the breeding area 33 flows from the water inlet 25 into the filtration tank unit 4, a water flow is generated near the water inlet 25 toward the water inlet 25. However, in front of the water inlet 25, the spout 42
An upward stream of water gushes from Therefore, even if the floating jellyfish approaches the water intake 25, the jellyfish does not remain attracted to the water intake 25,
It is pushed up by the flow of water spouted from spout 42.

Not all of the water sucked by the submersible pump 6 passes through the water inlet 25, and the total opening area of the water inlet 25 is smaller than the area of the suction port 13 of the submersible pump 6. Much larger. Therefore, the flow velocity of the water passing through the water inlet 25 is small, the flow is gentle, and there is no water pressure that continues to adsorb jellyfish.

The water that has passed through the holes 35 of the second permeable plate member 32 is filtered while passing through the layer of gravel 7, and most of the filtered water passes through the first permeable plate member 31. The water enters the water collecting channel 30 through the hole 34. On the other hand, the water that has not passed through the hole 34 of the first water-permeable plate member 31 passes through the water inlet 25 of the partition wall material 3 and joins with the filtered water in the empty space of the filtration tank unit 4,
It flows toward the suction port 13 of the submersible pump 6. And
The water that has entered the water collecting channel 30 flows through the channel 30 toward the submersible pump 6, is sucked from the suction port 13, and is supplied.

As described above, when the water in the breeding area 33 flows out of the hole 35 of the second water-permeable plate member 32 opened at the bottom, the water flows toward the hole 35 at the bottom, especially near the hole 35. A downward water flow occurs. However, since the total area of the hole 35 is much larger than the area of the suction port 13 of the submersible pump 6, the water flow generated in the vicinity of the hole 35 is a very gentle flow, and the water pressure that continues to adsorb jellyfish Will not occur. In the vicinity of the first and second ejection pipes 40 and 41, as described above,
Since the water jetted from the jets 42 and 43 generates an upward water flow, the flow direction of the water is reversed, and countless small turbulent flows are generated near the first and second jet pipes 40 and 41. Only a downward water flow is hardly generated. Therefore, even if the floating jellyfish descends to the bottom, the hole 3
5 does not remain sucked, but is swept away by the circulating flow and rises and floats again. In particular, the first
In the vicinity of the second ejection pipes 40 and 41, the jellyfish is not adsorbed to the bottom of the breeding area 33 (the second permeable plate member 32).

When the floating jellyfish descends on the circulating flow to the bottom of the rearing area 33,
It only comes into contact with the water-permeable plate-like member 32 and does not come into contact with the highly uneven gravel 7 (the bottom filtration material). Therefore, it is possible to reliably prevent the jellyfish from being damaged by contacting the bottom surface filtering material.

The flow path of the water sucked into the suction port 13 of the pump is not limited to the above-described embodiment.
The design can be changed as appropriate. For example, the suction port 13 and the water suction port 25 may be constituted by a filter, and the suction port 13 and the water suction port 25 are directed in a direction orthogonal to or opposite to the flow direction of the water in the breeding area 33 by suction. Alternatively, the ejection ports 42 and 43 may be arranged, or the ejection ports 43 may be arranged horizontally and ejecting in parallel with the second water-permeable plate member 32.

The flow of water generated in the breeding area 33 is preferably gentle as long as jellyfish and the like can float, and the direction of the flow is as described in the above embodiment.
It is not limited to the direction from the rear to the front and from the left to the right. For this reason, the arrangement of the first and second ejection pipes 40, 41 having the ejection ports 42, 43 opened is L
The design is not limited to the letter shape and can be changed as appropriate.

The first water-permeable plate-like member 31 is not limited to the sashimi-like plate, but may have a function of passing water and a function of supporting a filter material.
A perforated plate may be used. The second water-permeable plate-like member 32
As long as it has a function of passing water and a function of preventing passage of breeding organisms such as jellyfish, it may have a net-like shape or a pen-like shape.

Further, an illumination device may be provided on the lid 50 which covers the opening on the upper surface of the water tank main body 2 so as to illuminate jellyfish floating in the breeding area 33.

Further, a flow control valve is provided on the branch pipe 16 side of the shower pipe 17 or on the connecting pipe 18 so that the connecting pipe 1
8 by adjusting the amount of water flowing to
It can also be configured so that the flow rate of water from the water can be adjusted.

According to the present invention as described above, the following effects can be obtained. According to the first aspect of the present invention, the spout that is connected to the discharge side of the pump and ejects water pumped from the pump is orthogonal or opposite to the flow direction of the water sucked by the pump in the breeding area. The water flowing in the direction toward the pump is offset because the water is flowing toward the pump. The inconvenience of sticking to a specific part by pressure can be eliminated. Therefore, even aquatic organisms with low exercise ability, such as jellyfish, can be bred under an appropriate environment.

According to the second aspect of the present invention, the first water-permeable plate-like member is provided on the bottom surface of the water tank main body with a space serving as a water collecting channel, and the first water-permeable plate-like member is provided on the first water-permeable plate-like member. A filter material was laid, a second permeable plate member was provided above the filter material, a breeding area was provided above the second permeable plate member, and a pump sucked water in the water collecting channel. In addition, breeding organisms in the breeding area do not come into direct contact with the filter medium for bottom filtration. Therefore, even an organism such as a jellyfish which has little athletic ability and is easily damaged is not likely to be damaged. Also, the flow of water generated by the suction of the pump is dispersed at the bottom of the breeding area, and the power of the water flow is weakened. The inconvenience of sticking to the plate member can be eliminated.

According to the third aspect of the present invention, the pipe communicating with the discharge side of the pump is disposed substantially horizontally below the breeding area, and the spout is provided upward in this pipe. A circulating flow can be generated.
Therefore, when a jellyfish or the like is bred, the circulating flow allows the jellyfish or the like to float in the breeding area, and the ornamental effect can be improved.

According to the fourth aspect of the present invention, the inside of the water tank main body is partitioned into a filtration tank portion on the rear side and a rearing tank on the front side by the partition wall material, and the filtering material is loaded in the filtration tank portion. A water inlet that allows the water in the breeding tank to pass through the suction port side of the pump is opened, and a pipe that communicates with the discharge side of the pump is arranged in the lower part of the breeding tank in a substantially horizontal direction along the partition wall material. Since the outlet is provided upward in the pipe, even if water flows toward the filtration tank near the water intake, water is ejected upward from the outlet of the pipe to this part. Even if a floating jellyfish or the like is attracted to the water inlet, the flow of water spouted from the spout raises the jellyfish or the like. Therefore,
It is possible to prevent jellyfish and the like from being adsorbed to the water inlet.

According to the fifth aspect of the present invention, in addition to the fourth aspect of the present invention, the pipe is disposed in a substantially horizontal direction along the lower side of the rearing tank, and the spout is directed horizontally or upward to the pipe. Since water is spouted horizontally or upward from the spout of the pipe, the flow of water spouted from the spout is not affected even if floating jellyfish etc. And so on. Therefore, it is possible to prevent jellyfish and the like from being adsorbed to the water inlet.
