Thereby, the beauty | look of the water tank 1 can further be improved.

  Further, as shown in FIG. 8, a power source that is formed between the rear plate 5 and the rear cover body 8 of the water tank body 2 and is formed by a gap between the two and 8 and from the other end opening 51 b of the first passage 51. Since the second passage 55 through which the cord portion 61b is passed is formed, by passing the power cord portion 61b extended from the other end opening 51b of the first passage 51 through the second passage 55, Even when viewed from the side, the power cord portion 61b is concealed by the rear cover body 8, whereby the aesthetic appearance of the water tank 1 can be further improved.

  In the water tank 1 of the present embodiment, the water receiving plate 10 receives the water 40 (filtered water 40a) supplied onto the water receiving plate 10 (that is, on the upper surface 11 of the water receiving plate 10) in a substantially horizontal direction. Therefore, the contact area and contact time of the water 40 with the air can be increased, so that the oxygen can be reliably taken into the water 40.

  Furthermore, since this water receiving plate 10 is arranged in a state of covering substantially the entire surface of the water surface 41 in the water tank body 2 at a position spaced upward from the water surface 41 in the water tank body 2, this aquarium fish tank No. 1 has a novel structure that is not found in conventional water tanks, and has an enhanced preference.

  Moreover, since the water receiving plate 10 drops the water 40 (filtrated water 40a) supplied on the water receiving plate 10 into the water tank body 2 in a film shape, the contact area of the water 40 with the air and The contact time can be further increased, so that oxygen can be more reliably taken into the water 40, and the taste can be further enhanced.

  Further, since the lid body 30 for the aquarium body 2 is disposed at a position spaced upward from the water receiving plate 10, dust floating in the air falls on the water receiving plate 10 and flows there. It is possible to prevent the lid 30 from flowing into the water tank body 2 together with the water 40 (filtered water 40a).

  In addition, since the lid 30 is disposed at a position spaced upward from the water receiving plate 10, the water is passed through the gap between the water receiving plate 10 and the lid 30 from the outside of the water tank body 2. The water 40 flowing on the receiving plate 10 and the film-like water 40 falling from the water receiving plate 10 can be seen. Thereby, high preference can be maintained.

  In addition, since the lid 30 is arranged at a position higher than the upper opening peripheral edge 2a of the aquarium body 2, the tank 30 can be provided without bothering to remove the lid 30 from the aquarium body 2 when feeding the aquarium fish. If a bait | feed is thrown into the water receiving plate 10 from the clearance gap 71 between the upper opening periphery 2a of the main body 2 and the cover body 30, a water tank main body with the water 40 (filtered water 40a) which a bait | flow will flow on the water receiving plate 10 Since it falls in 2, feeding to an ornamental fish can be performed easily.

  Further, the water receiving plate 10 is light-transmitting, and the illumination tool 31 is disposed at a position spaced apart from the water receiving plate 10 on the upper side (in the lid body 30 in this embodiment). When the illumination tool 31 illuminates the water tank body 2 from the upper side of the water receiving plate 10, the illumination light sequentially passes through the water 40 flowing on the water receiving plate 10 and the water receiving plate 10. Therefore, the water 40 in the water tank main body 2 can be illuminated, and furthermore, the illumination light is fluctuated by the water 40 flowing on the water receiving plate 10, so that the illumination effect can be improved.

  Moreover, the water 40 in the water tank body 2 is sucked from the rear side of the water tank body 2 into the filter housing space 6 formed on the upper part of the rear plate 5 in the water tank body 2 as the rear side in the water tank body 2. The water receiving plate 10 is a water tank on which the filtered water 40a filtered by the filter 20 is used as the water 40 supplied onto the water receiving plate 10. Since it flows from the rear side of the main body 2 to the front side and drops onto the front part of the water surface 41 in the water tank body 2 from the front edge 19 of the water receiving plate 10, as described above, Water 40 circulates. Here, the dropping position of the filtered water 40a falling from the front edge 19 of the water receiving plate 10 is the front part in the aquarium body 2, while the suction position of the water 40 in the aquarium body 2 sucked by the filter 20 ( That is, the position of the suction port 24 of the filter 20) is the rear end of the water tank main body 2, so that the distance between the dropping position and the suction position is long. Therefore, substantially all of the water 40 in the water tank body 2 is sucked and filtered by the filter 20 until the filtered water 40a that has fallen into the water tank body 2 reaches the suction position from the dropping position. Therefore, it can filter efficiently with respect to the water 40 in the water tank main body 2, and can make oxygen take in into the water 40 in the water tank main body 2 more reliably.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

  For example, in the present embodiment, the underwater device 60 is the electric heater 61, but in the present invention, the underwater device 60 is not limited to the electric heater 61, and for example, oxygen is added to the water 40 in the aquarium body 2. May be an air ejector that ejects air into the water 40 in the form of bubbles, a water circulation pump for circulating the water 40 in the water tank body 2, or an electric heater. 61, Two or more of the air ejector and the water circulation pump may be used. When the underwater device 60 is an air ejector, an air ejection portion such as an air stone corresponds to the main body portion of the underwater device 60, and an air feed tube that sends air to the air ejection portion corresponds to a cord portion of the underwater device. . When the underwater device 60 is a water circulation pump, the pump main body corresponds to the main body portion of the submersible device 60, and the power cord portion for introducing operation electricity to the pump main body corresponds to the cord portion of the underwater device 60. It becomes.
