[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of a water circulation type water tank apparatus according to the present invention will be described in detail with reference to the drawings.

[0007] Figure 1 (A) ~ FIG 1 (C) is a diagram showing the configuration of a vicinity of corner portions of water circulation type water tank 101, which is an actual <br/> facilities embodiment of the present invention. The water circulation type water tank apparatus 101 includes an angle base (not shown) similar to the above-described conventional water circulation type water tank apparatus 200, and a water tank 2 supported on the angle base.
, A control box (not shown), a filtration tank (not shown) installed below the water tank 2, and a water reduction mechanism (not shown). The difference from the conventional water circulating water bath device 200 water circulating water bath 101 is above this embodiment, the overflow pipe 1 corners of the tub 2
This is the structure around 0.

As shown in FIGS. 1 (A) to 1 (C), a corner cover 16 is attached to two corners of the water tank 2 of the water circulation type water tank apparatus 101 by bonding or the like to two side surfaces of the water tank 2. Fixed. Almost the upper half of the corner cover 16
It is formed in a substantially L-shaped cross-sectional shape and surrounds substantially the upper half of the overflow pipe 10 in the water tank 2. Further, substantially lower halves of the corner cover 16 are elongated restricting portions 16a and 16b extending downward from the left and right ends of the substantially L-shaped cross-sectional member. For this reason, almost the lower half of the corner cover 16 is mostly cut out to form an opening 16c.

On the outside of the regulating portions 16a and 16b,
At predetermined intervals, parallel to the regulating portions 16a and 16b,
Elongated strip-shaped pressing members 17a and 17b are fixed to two side surfaces of the water tank 2 by bonding or the like. Therefore, the regulating portions 16a and 16b below the corner cover 16 and the pressing members 17a and 17b form groove-shaped guide concave portions 19a and 19b between them (see FIG. 1B).

A detachable cover 18 having a substantially L-shaped cross section can be attached to and detached from the guide recesses 19a and 19b (see FIG. 1C). The vertical length of the removable cover 18 is formed to be longer than the vertical length of the opening 16c. In addition, a slit-shaped water intake opening 18a is provided below the detachable cover 18.

With the above construction, the opening 16 can be opened by inserting the detachable cover 18 from above and fitting the left and right ends of the detachable cover 18 into the guide recesses 19a and 19b.
c can also surround the lower half of the overflow pipe 10 exposed from the c.
Since it surrounds throughout 0, putting Ri taken the water in the water tub 2 from intake opening 18a, the overflow pipe 10
The water can be circulated by being guided to the upper opening of the tub, and large trash and fish can be prevented from entering the overflow pipe 10.

When dust G has settled around the lower portion of the overflow pipe 10, the detachable cover 18 can be pulled out upward, and only the detachable cover 18 can be removed from the water tank 2, thereby opening the opening 16c. Accordingly, dust G and the like settled near the lower portion of the overflow pipe 10 can be easily cleaned.

[0013] The present invention is not limited to the embodiments described above. The embodiment described above is an exemplification, and has substantially the same configuration as the technical idea described in the claims of the present invention, and has the same function and effect,
Anything is included in the technical scope of the present invention.

[0014] For example, in the above embodiment, the regulating portions 16a, 16b and the pressing member 17a, 17b Togabetsu body
If the has been described as an example of the present invention is not limited to this, it may be integrally formed. For example, the regulating portion 16a and the pressing member 17a may be connected by a plate-shaped portion (not shown), and the pressing member 17a may be a part of the corner cover 16. About pressing member 17 b is the same. With this configuration, it is not necessary to measure the width of the guide concave portion and the like and to arrange the pressing member, and the manufacture of the corner portion of the water tank device becomes easier.

Further, in the implementation form described above, mounting and demounting the removable cover against water tank by connecting or disconnecting by fitting the end portion of the removable cover to the groove-shaped guide recess provided in the side surface of the tank Although the example has been described, the present invention is not limited to this. For example, one ridge is provided on the side surface of the water tank, a groove-shaped guide recess is formed at the end of the detachable cover, and the guide is formed on the ridge. even if the removable cover by inserting or removing by fitting the recesses to be detachable from the water tank <br/> have good.

Further, in the implementation form described above, an example has been described using a member having a substantially L-shaped cross-sectional shape as a removable cover, the present invention is not limited thereto, other cross-sectional shape of the member, e.g. , 1/4 of a cylinder or 1 of an elliptical cylinder
A member having a section of / 4 may be used. In short, it is only necessary to surround the overflow pipe.

[0017]

As described above, according to the present invention,
Around the overflow pipe of the water circulation type water tank device that circulates water and breeds live fish etc., the corner fixed to the water tank
And Kaba, since surrounded by detachably configured removable cover against water tank having a water intake opening capable put Ri taken with water at the bottom, putting Ri taken water from intake opening of the removable cover overflow pipe of the upper opening In addition to being able to circulate the water, the detachable cover can be removed from the water tank to easily clean the vicinity of the lower portion of the overflow pipe.
