本発明は以下の効果を奏する。   The present invention has the following effects.

上記［１］記載の観賞魚用水槽では、水受け板が、該水受け板上に供給された水を略水平方向に受け流して水槽本体内へ落下させるものであることにより、水の空気との接触面積及び接触時間を増加させることができ、もって水に酸素を確実に取り込ませることができる。   In the aquarium fish tank according to the above [1], the water receiving plate receives water supplied on the water receiving plate in a substantially horizontal direction and drops it into the water tank main body, thereby The contact area and contact time can be increased, so that oxygen can be reliably taken into water.

さらに、この水受け板は、水槽本体内の水面に対して上側に離間した位置に水槽本体内の水面の略全面を覆う状態に配置されているから、この観賞魚用水槽は従来の水槽にはない新規な構造を有しており、趣向性が高められている。   Furthermore, since this water receiving plate is disposed in a state of covering the substantially entire surface of the water surface in the aquarium body at a position spaced above the water surface in the aquarium body, this aquarium fish tank is a conventional aquarium. It has no new structure, and the taste is enhanced.

上記［２］記載の観賞魚用水槽では、水受け板は、該水受け板上に供給された水を水槽本体内へすだれ状乃至膜状に落下させるものであるから、水の空気との接触面積及び接触時間を更に増加させることができ、もって水に酸素を更に確実に取り込ませることができるし、趣向性を更に高めることができる。   In the aquarium fish tank according to the above [2], the water receiving plate drops water supplied on the water receiving plate into the water tank body in the form of a comb or film. The contact area and contact time can be further increased, so that oxygen can be more reliably taken into water, and the taste can be further enhanced.

上記［３］記載の観賞魚用水槽では、水受け板の上面に水の流れ方向に延びた凸条が、複数個、水の流れ方向に対して略直交する方向に間隔をおいて並んで形成されていることにより、水受け板から落下する水をすだれ状乃至膜状に確実に実現することができる。   In the ornamental fish tank described in [3] above, a plurality of ridges extending in the water flow direction are arranged on the upper surface of the water receiving plate at intervals in a direction substantially perpendicular to the water flow direction. By being formed, the water falling from the water receiving plate can be surely realized in an interdigital or film shape.

上記［４］記載の観賞魚用水槽では、空気中を漂う埃等が水受け板上に落下してここを流れる水と一緒に水槽本体内に流入するのを水槽本体用の蓋体によって防止することができる。   In the aquarium for aquarium fish described in [4], the lid for the aquarium body prevents dust and the like floating in the air from falling onto the water receiving plate and flowing into the aquarium body together with the water flowing therethrough. can do.

しかも、この蓋体は、水受け板に対して上側に離間した位置に配置されているので、水槽本体の外側から水受け板と蓋体との間の隙間を介して水受け板上を流れる水や水受け板から落下する水を見ることができる。これにより、趣向性を更に高めることができる。   In addition, since the lid is arranged at a position spaced upward from the water receiving plate, it flows on the water receiving plate from the outside of the water tank body through the gap between the water receiving plate and the lid. You can see water and water falling from the water tray. Thereby, preference can be improved further.

上記［５］記載の観賞魚用水槽では、光透性を有する水受け板の上側から照明具により水槽本体の内側に向けて照明をすると、その照明光が水受け板上を流れる水及び水受け板を順次透過するので、水槽本体内の水を照明することができる。さらに、水受け板上を流れる水によって照明光が揺らぐので、照明効果を向上させることができる。   In the aquarium for ornamental fish described in [5] above, when illumination is performed from the upper side of the light-receiving water receiving plate toward the inside of the main body of the water tank with a lighting tool, the water and water that flows on the water receiving plate Since it permeate | transmits a receiving plate sequentially, the water in a water tank main body can be illuminated. Furthermore, since the illumination light fluctuates due to the water flowing on the water receiving plate, the illumination effect can be improved.

上記［６］記載の観賞魚用水槽では、水槽本体内の水が該水槽本体の後部側から濾過器により吸い込まれる。そして、吸い込まれた水が該濾過器により濾過され、この濾過水が水受け板上に供給されて該水受け板上を水槽本体の後部側から前部側に流れて水受け板の前端縁から水槽本体内の前部へ落下される。そして、落下した濾過水は濾過器により水槽本体の後部側へ吸い寄せられて再度吸い込まれる。このように、水槽本体内の水は、その後部側から濾過器及び水受け板上を順次通過して水槽本体内の前部に落下した後、水槽本体内の後部側へ吸い寄せられるという順路で循環する。ここで、水受け板の前端縁から落下する濾過水の落下位置は水槽本体内の前部であり、一方、濾過器により吸い込まれる水槽本体内の水の吸い込み位置は水槽本体内の後部側であるから、落下位置と吸い込み位置との距離は長い。したがって、水槽本体内に落下した濾過水がその落下位置から吸い込み位置に到達するまでの間に、水槽本体内の水の略全部が濾過器により吸い込まれて濾過されることになるため、水槽本体内の水に対して効率良く濾過することができるし、更に、水槽本体内の水に対して酸素をより一層確実に取り込ませることができる。   In the aquarium fish tank described in [6] above, the water in the tank body is sucked from the rear side of the tank body by the filter. Then, the sucked water is filtered by the filter, and this filtered water is supplied onto the water receiving plate and flows on the water receiving plate from the rear side to the front side of the water tank main body, thereby leading the front edge of the water receiving plate. To the front of the tank body. And the fallen filtered water is sucked by the filter toward the rear side of the water tank body and sucked again. In this way, the water in the aquarium body passes through the filter and the water receiving plate sequentially from the rear side and falls to the front part in the aquarium body, and then is sucked to the rear side in the aquarium body. Circulate. Here, the falling position of the filtered water falling from the front edge of the water receiving plate is the front part in the water tank body, while the water suction position in the water tank body sucked by the filter is on the rear side in the water tank body. There is a long distance between the drop position and the suction position. Therefore, since almost all of the water in the water tank body is sucked and filtered by the filter before the filtered water falling into the water tank body reaches the suction position from the dropping position, the water tank body The water in the tank can be filtered efficiently, and oxygen can be taken into the water in the water tank body more reliably.

上記［７］記載の観賞魚用水槽では、水受け板の上面が水の流れ方向において凹凸状に形成されているので、水受け板上を流れる水が凹凸によって乱され、これにより水に酸素を更に一層確実に取り込ませることができる。さらに、もし水受け板が光透性を有するものでありその上側に水槽本体の内側に向けて照明をする照明具が配置されている場合には、水受け板上を流れる水が凹凸によって乱されることで照明光が更に揺らぐので、照明効果を更に向上させることができる。   In the ornamental fish tank described in [7] above, since the upper surface of the water receiving plate is formed in an uneven shape in the direction of water flow, the water flowing on the water receiving plate is disturbed by the unevenness, whereby oxygen is added to the water. Can be taken in even more reliably. Furthermore, if the water receiving plate is light-transmitting and a lighting fixture that illuminates toward the inside of the aquarium body is disposed on the upper side, the water flowing on the water receiving plate is disturbed by unevenness. As a result, the illumination light further fluctuates, so that the illumination effect can be further improved.

次に、本発明の一実施形態について図面を参照して以下に説明する。   Next, an embodiment of the present invention will be described below with reference to the drawings.

本発明の一実施形態に係る観賞魚用水槽１は、図１〜４に示すように、水槽本体２、水槽本体２用の蓋体３０、水受け板１０、濾過器２０などを具備している。   As shown in FIGS. 1 to 4, the aquarium fish tank 1 according to one embodiment of the present invention includes a water tank body 2, a lid 30 for the water tank body 2, a water receiving plate 10, a filter 20, and the like. Yes.

水槽本体２は、前板３、左板４、右板４、後板５及び底板７を有する上方が開口した四角箱状のものである。これら前板３、左右各板４、４、後板５及び底板７は、水槽本体２内の水４０が水槽本体２の外側に漏出しないように水４０を遮蔽するものである。前板３と左右各板４、４はそれぞれ透明のプラスチック又はガラス製である。後板５は透明又は不透明のプラスチック製である。また、図３に示すように、底板７上には底砂７ａが敷設されている。   The aquarium body 2 has a square box shape with an upper opening having a front plate 3, a left plate 4, a right plate 4, a rear plate 5 and a bottom plate 7. The front plate 3, the left and right plates 4, 4, the rear plate 5, and the bottom plate 7 shield the water 40 so that the water 40 in the water tank body 2 does not leak outside the water tank body 2. The front plate 3 and the left and right plates 4 and 4 are each made of transparent plastic or glass. The back plate 5 is made of transparent or opaque plastic. As shown in FIG. 3, bottom sand 7 a is laid on the bottom plate 7.

さらに、この水槽本体２では、図３及び４に示すように、後板５の上板部５ａはその下板部５ｂよりも後側に配置されるとともに、上板部５ａと下板部５ｂとが水平状の段板部５ｃを介して互いに一体に連結されており、そのため後板５の上板部５ａと下板部５ｂとの間に段差が生じている。これにより、水槽本体２内における後板５の上部（即ち水槽本体２内の後部側）に、段板部５ｃよりも上側の段差空間からなる濾過器収容空間６が水槽本体２の内向き及び上向きに開いて形成されている。さらに、この濾過器収容空間６の少なくとも下部は、水槽本体２内の水面４１よりも下側に配置されており、本実施形態では、濾過器収容空間６の下部だけが水槽本体２内の水面４１よりも下側に配置される一方、濾過器収容空間６の上部は水面４１よりも上側に配置されている。   Furthermore, in this water tank main body 2, as shown in FIGS. 3 and 4, the upper plate portion 5a of the rear plate 5 is disposed on the rear side of the lower plate portion 5b, and the upper plate portion 5a and the lower plate portion 5b. Are integrally connected to each other via a horizontal step plate portion 5c, so that a step is generated between the upper plate portion 5a and the lower plate portion 5b of the rear plate 5. As a result, the filter housing space 6 formed of a step space above the step plate portion 5c is formed inwardly of the water tank body 2 above the rear plate 5 in the water tank body 2 (that is, the rear side in the water tank body 2). It is formed to open upward. Furthermore, at least the lower part of the filter housing space 6 is disposed below the water surface 41 in the water tank body 2. In this embodiment, only the lower part of the filter housing space 6 is the water surface in the water tank body 2. On the other hand, the upper portion of the filter housing space 6 is disposed above the water surface 41.

さらに、この後板５（詳述すると後板５の上板部５ａ及び下板部５ｂ）に対して後側に離間した位置には、後板５の後外面を覆う後カバー体８が配置されるとともに、この後カバー体８の左右各端部が水槽本体２の左右各板４、４の後端部に分離可能に固定され、更に、この後カバー体８の左右各端部の上縁部が水槽本体２の左右各板４、４の後端部の上縁部に分離可能に固定されている。したがって、図３に示すように、後板５と後カバー体８との間には隙間が形成されている。   Further, a rear cover body 8 that covers the rear outer surface of the rear plate 5 is disposed at a position spaced rearward from the rear plate 5 (more specifically, the upper plate portion 5a and the lower plate portion 5b of the rear plate 5). In addition, the left and right end portions of the rear cover body 8 are separably fixed to the rear end portions of the left and right plates 4 and 4 of the water tank main body 2. The edge is separably fixed to the upper edge of the rear end of each of the left and right plates 4 and 4 of the water tank body 2. Therefore, as shown in FIG. 3, a gap is formed between the rear plate 5 and the rear cover body 8.

濾過器２０は、該濾過器２０の少なくとも下部が水槽本体２内の水４０中に浸漬される状態に配置されて使用される薄型のものであり、図３に示すように、そのプラスチック製ケーシング２１の内部には濾過材２３及び水循環水中ポンプ２２が収納配置されている。なお本発明では、水循環ポンプ２２はケーシング２１の内部に必ずしも収容されていることを要せず、例えばケーシング２１に付設されていても良い。そして、図３、４及び６に示すように、この濾過器２０が水槽本体２内における後板５の上部に形成された上記濾過器収容空間６内に上方から取り出し可能に縦置きに収容配置されている。この収容状態において、濾過器２０は水槽本体２の後板５の段板部５ｃ上に載置されるとともに、後カバー体８の左右各端部の上縁部に設けられた前後一対の保持片８ａ、８ａ間に上方から濾過器２０の左右各端部がスライド挿入されることで濾過器２０が濾過器収容空間６から脱落しないように保持されている。こうして、濾過器２０は水槽本体２内の後部に取り出し可能に配置されている。さらに、濾過器２０のケーシング２１の前面２０ａ（即ち水槽本体２の内方に向いた面）は、後板５の下板部５ｂの内面に対して上下方向に略面一（つらいち）に連なっている。   The filter 20 is a thin type that is disposed and used in a state in which at least the lower part of the filter 20 is immersed in the water 40 in the aquarium body 2, and as shown in FIG. A filter medium 23 and a water circulation submersible pump 22 are accommodated in the interior 21. In the present invention, the water circulation pump 22 is not necessarily housed in the casing 21, and may be attached to the casing 21, for example. As shown in FIGS. 3, 4 and 6, the filter 20 is vertically placed in the filter housing space 6 formed in the upper part of the rear plate 5 in the water tank body 2 so that it can be taken out from above. Has been. In this accommodated state, the filter 20 is placed on the step plate portion 5 c of the rear plate 5 of the water tank body 2 and a pair of front and rear holding members provided at the upper edge portions of the left and right ends of the rear cover body 8. The right and left ends of the filter 20 are slid between the pieces 8a and 8a from above, so that the filter 20 is held so as not to drop out of the filter housing space 6. Thus, the filter 20 is disposed so as to be removable at the rear part in the water tank body 2. Further, the front surface 20a of the casing 21 of the filter 20 (that is, the surface facing inward of the water tank body 2) is substantially flush with the inner surface of the lower plate portion 5b of the rear plate 5 in the vertical direction. It is lined up.

さらに、図４及び６に示すように、この濾過器２０のケーシング２１の前面２０ａの下部には、該ケーシング２１内の水循環ポンプ２２（図３参照）の吸引力によって水槽本体２内の水４０をケーシング２１内に吸い込む際に水４０が通過する複数のスリット状吸い込み口２４が設けられている。この吸い込み口２４から吸い込まれた水は、水循環ポンプ２２の動力によってケーシング２１内の濾過材２３を通過することで濾過されて濾過水４０ａとなるとともに、この濾過水４０ａがケーシング２１の前面２０ａの上端部に形成された幅広の吐出口２５から水槽本体２内において前向きに吐出される。吐出口２５の幅寸法は、水槽本体２の左右両板４、４間の幅寸法と略同寸に設定されている。   Further, as shown in FIGS. 4 and 6, the water 40 in the aquarium body 2 is formed in the lower part of the front surface 20 a of the casing 21 of the filter 20 by the suction force of the water circulation pump 22 (see FIG. 3) in the casing 21. A plurality of slit-like suction ports 24 through which water 40 passes when the air is sucked into the casing 21 are provided. The water sucked from the suction port 24 is filtered by passing through the filter medium 23 in the casing 21 by the power of the water circulation pump 22 to be filtered water 40a. From the wide discharge port 25 formed in the upper end portion, the water is discharged forward in the water tank body 2. The width of the discharge port 25 is set to be approximately the same as the width between the left and right plates 4, 4 of the water tank body 2.

水受け板１０は、光透性を有する無色透明プラスチック製のものであり、図３及び７に示すように、水槽本体２内の水面４１に対して上側に離間するとともに水槽本体２の上開口周縁２ａよりも若干低い高さ位置に、該水面４１の略全面（詳述すると、平面視において水面４１の全面積に対して８０％以上（好ましくは９０％以上）を覆う状態に略水平に配置されている。   The water receiving plate 10 is made of a light-transmitting colorless and transparent plastic, and as shown in FIGS. 3 and 7, the water receiving plate 10 is spaced apart from the water surface 41 in the water tank main body 2 and opened upward in the water tank main body 2. At a position slightly lower than the peripheral edge 2a, the surface of the water surface 41 is substantially horizontally covered so as to cover 80% or more (preferably 90% or more) of the entire area of the water surface 41 in plan view.

この水受け板１０は、その上面１１上に供給された水４０を略水平方向に受け流して水槽本体２内へすだれ状乃至膜状に落下させるものである。本実施形態では、図１及び３に示すように、水受け板１０は、その上面１１上に供給される水４０として、濾過器２０の吐出口２５から吐出された濾過水４０ａを、水受け板１０の上面１１上における水槽本体２の後部側から前部側へ受け流して水受け板１０の前端縁１９から水槽本体２内の水面４１の前部上へ膜状に落下させるものである。なお、水受け板１０の前端縁１９と水槽本体２の前板３との間には隙間が水平方向に生じている。   The water receiving plate 10 receives the water 40 supplied on the upper surface 11 in a substantially horizontal direction and drops it into the water tank main body 2 in a comb or film shape. In this embodiment, as shown in FIGS. 1 and 3, the water receiving plate 10 receives the filtered water 40 a discharged from the discharge port 25 of the filter 20 as the water 40 supplied onto the upper surface 11. The water is received from the rear side of the water tank main body 2 on the upper surface 11 of the plate 10 to the front side, and dropped from the front edge 19 of the water receiving plate 10 onto the front part of the water surface 41 in the water tank main body 2 in the form of a film. A gap is formed in the horizontal direction between the front edge 19 of the water receiving plate 10 and the front plate 3 of the water tank body 2.

図５に示すように、水受け板１０の左右両端縁には左右一対の立ち上がり状の側板部１５ａ、１５ａが該水受け板１０の前後方向に連続して一体形成されている。水受け板１０の後端縁には後板部１５ｂが左右方向に連続して立ち上がり状に一体形成されている。さらに、左右各側板部１５ａの上端部の前部及び後部には、それぞれ外側方突出状の係止片１６、１６が一体形成されている。そして、図７に示すように、これらの係止片１６が水槽本体２の左右各板４、４の上縁部及び後カバー体８の左右各端部の上縁部に上方から係脱可能に係止されており、これにより、水受け板１０が水槽本体２内の所定高さ位置に取外し可能に配置されている。なお図５において、
また、図３及び５に示すように、水受け板１０の上面１１の後部には、濾過水４０ａを一時的に溜める貯留凹部１２が水受け板１０の左右両側板部１５ａ、１５ａ間の全領域に亘って形成されている。また、水受け板１０の上面１１の前部における左右方向中間部には、貯留凹部１２内に溜まった濾過水４０ａが流出する幅広の溝部１３が貯留凹部１２から水受け板１０の前端縁１９まで僅かに下勾配状に傾斜して且つ連続して形成されている。この溝部１３の深さは貯留凹部１２の深さよりも若干浅くなっており、またこの溝部１３の幅寸法は、水受け板１０の左右両側板部１５ａ、１５ａ間の幅寸法に対して約１／３〜１／２倍に設定されている。さらに、図５に示すように、この溝部１３は、平面視において恰も川のように左右方向の一方側に僅かに円弧状に曲がって形成されている。さらに、水受け板１０の上面１１における溝部１３の左右両外側部には、それぞれ水草を模した装飾模様１７が刻設されている。 As shown in FIG. 5, a pair of left and right rising side plate portions 15 a and 15 a are integrally formed on the left and right end edges of the water receiving plate 10 continuously in the front-rear direction of the water receiving plate 10. A rear plate portion 15b is integrally formed on the rear end edge of the water receiving plate 10 so as to rise up continuously in the left-right direction. Furthermore, locking pieces 16, 16 that protrude outward are integrally formed at the front and rear of the upper end of each of the left and right side plate portions 15a. As shown in FIG. 7, these locking pieces 16 can be engaged and disengaged from above on the upper edge portions of the left and right plates 4, 4 of the water tank body 2 and the upper edge portions of the left and right ends of the rear cover body 8. Accordingly, the water receiving plate 10 is detachably disposed at a predetermined height position in the water tank main body 2. In FIG.
Further, as shown in FIGS. 3 and 5, a storage recess 12 for temporarily storing filtered water 40 a is provided at the rear portion of the upper surface 11 of the water receiving plate 10, between the left and right side plate portions 15 a and 15 a of the water receiving plate 10. It is formed over the region. In addition, a wide groove portion 13 through which filtered water 40a accumulated in the storage recess 12 flows out from the front end edge 19 of the water support plate 10 from the storage recess 12 is provided in the middle portion in the left-right direction at the front portion of the upper surface 11 of the water receiving plate 10. Inclined slightly downward and continuously. The depth of the groove 13 is slightly shallower than the depth of the storage recess 12, and the width of the groove 13 is about 1 with respect to the width between the left and right side plates 15 a, 15 a of the water receiving plate 10. / 3 to 1/2 times. Further, as shown in FIG. 5, the groove 13 is formed in a slightly arcuate shape on one side in the left-right direction like a river in a plan view. Furthermore, decorative patterns 17 simulating aquatic plants are engraved on the left and right outer sides of the groove 13 on the upper surface 11 of the water receiving plate 10.

さらに、この水受け板１０の上面１１において、図５に示すように、貯留凹部１２の底面１２ａと溝部１３の底面１３ａとからなる領域のうち少なくとも溝部１３の底面１３ａには、水受け板１０の後部側（即ち貯留凹部１２側）から水の流れ方向（即ち水槽本体２及び水受け板１０の前後方向）に延びた断面円弧状又は三角形状の分流用凸条１４が、複数個、水の流れ方向に対して略直交する方向（即ち水槽本体２及び水受け板１０の左右方向）に間隔をおいて並んで形成されている。この各凸条１４は、水受け板１０の上面１１上に供給された濾過水４０ａが貯留凹部１２から溝部１３内を流れる際に濾過水４０ａを各凸条１４の両側に分流させることで、該溝部１３内を流れる濾過水４０ａの流量について溝部１３の幅方向における均一化を図るためのものである。さらに、各凸条１４の下流端（即ち各凸条１４の前端）は、水受け板１０の前端縁１９よりも若干後側に位置しており、これにより、溝部１３内における互いに隣り合う２つの凸条１４、１４間を流れる分流水が水受け板１０の前端縁１９から落下する際に隣りの分流水と合流して確実に膜状に落下しうるものとなされている。なお、もし各凸条１４の下流端（即ち各凸条１４の前端）が水受け板１０の前端縁１９よりも後側ではなく水受け板１０の前端縁１９に位置している場合には、溝部１３内における互いに隣り合う２つの凸条１４、１４間を流れる分流水は水受け板１０の前端縁１９から落下する際に隣りの分流水と殆ど合流せず、すだれ状（櫛歯状）に落下するものとなる。   Further, on the upper surface 11 of the water receiving plate 10, as shown in FIG. 5, at least the bottom surface 13 a of the groove 13 out of the region composed of the bottom surface 12 a of the storage recess 12 and the bottom surface 13 a of the groove 13 is provided on the water receiving plate 10. A plurality of branching ridges 14 having a circular arc or triangular cross section extending in the direction of water flow (that is, the front-rear direction of the water tank body 2 and the water receiving plate 10) from the rear side (that is, the storage recess 12 side), Are formed side by side in the direction substantially perpendicular to the flow direction (that is, the left and right direction of the water tank body 2 and the water receiving plate 10). Each of the ridges 14 divides the filtered water 40a to both sides of each ridge 14 when the filtered water 40a supplied on the upper surface 11 of the water receiving plate 10 flows from the storage recess 12 into the groove 13. The flow rate of the filtered water 40a flowing through the groove 13 is to make the groove 13 uniform in the width direction. Furthermore, the downstream end of each ridge 14 (that is, the front end of each ridge 14) is located slightly rearward of the front end edge 19 of the water receiving plate 10, so that 2 adjacent to each other in the groove 13. When the diversion water flowing between the two ridges 14 and 14 falls from the front end edge 19 of the water receiving plate 10, the diversion water merges with the adjacent diversion water and can surely fall into a film shape. If the downstream end of each ridge 14 (that is, the front end of each ridge 14) is located not at the rear side of the front edge 19 of the water receiving plate 10 but at the front edge 19 of the water receiving plate 10. The diversion water flowing between the two adjacent ridges 14, 14 in the groove 13 hardly merges with the adjacent diversion water when falling from the front edge 19 of the water receiving plate 10, and is interdigital (comb-like) ) Will fall.

蓋体３０は、プラスチック製のものであり、図１及び３に示すように、水受け板１０に対して上側に離間した高さ位置であって更には水槽本体２の上開口周縁２ａよりも上側の高さ位置に、水槽本体２の後部側から前方へ水槽本体２の上開口を概ね覆うように軒（のき）状に延びて略水平に配置されている。この状態において、蓋体３０と水槽本体２との間には上下方向に第１隙間５１が生じている。さらに、水槽１の平面視において、蓋体３０の外周縁における前縁部３０ａが水槽本体２の上開口周縁２ａにおける前縁部２ｂよりも内側に配置されており（図３参照）、これにより、蓋体３０の外周縁における前縁部３０ａと水槽本体２の上開口周縁２ａにおける前縁部２ｂとの間に、第２隙間５２が水平方向に生じている。   The lid body 30 is made of plastic, and as shown in FIGS. 1 and 3, the lid body 30 is at a height position spaced upward from the water receiving plate 10, and further than the upper peripheral edge 2 a of the water tank body 2. At the upper height position, it extends in the shape of an eave (spread) so as to substantially cover the upper opening of the water tank body 2 from the rear side of the water tank body 2 to the front, and is disposed substantially horizontally. In this state, a first gap 51 is formed between the lid 30 and the water tank body 2 in the vertical direction. Furthermore, the front edge part 30a in the outer periphery of the cover body 30 is arrange | positioned inside the front edge part 2b in the upper opening periphery 2a of the water tank main body 2 in planar view of the water tank 1 (refer FIG. 3), thereby A second gap 52 is formed in the horizontal direction between the front edge 30a at the outer peripheral edge of the lid 30 and the front edge 2b at the upper opening peripheral edge 2a of the water tank body 2.

さらに、この蓋体３０は、水槽本体２の後端部（詳述すると後カバー体８）の上端部に分離可能に取り付けられている。   Further, the lid body 30 is detachably attached to the upper end portion of the rear end portion of the water tank main body 2 (more specifically, the rear cover body 8).

また、図３に示すように、この蓋体３０の内部（即ち、水受け板１０に対して上側に離間した位置）には、水槽本体２の内側に向けて照明をする照明具３１が配置されている。この照明具３１は、詳述すると照明光源として複数のＬＥＤを有するもの、即ちＬＥＤ照明具であり、蓋体３０の上面に設けられた円盤状の調光操作ダイヤル３３を手で回転させることでその光量（明るさ）を調整しうるように構成されている。なお、３４は、ダイヤル３３を操作することで調光された照明具３１の調光状態を表示する表示部である。３２は、照明具３１についての防滴用透光板である。   Further, as shown in FIG. 3, an illuminator 31 that illuminates the inside of the aquarium body 2 is disposed inside the lid body 30 (that is, a position spaced upward from the water receiving plate 10). Has been. In detail, the illumination tool 31 has a plurality of LEDs as an illumination light source, that is, an LED illumination tool. By rotating a disk-shaped dimming operation dial 33 provided on the upper surface of the lid 30 by hand. The amount of light (brightness) can be adjusted. Reference numeral 34 denotes a display unit that displays the dimming state of the lighting fixture 31 that is dimmed by operating the dial 33. Reference numeral 32 denotes a drip-proof translucent plate for the lighting fixture 31.

本実施形態の観賞魚用水槽１では、図３に示すように、水槽本体２内の水４０中に観賞魚（図示せず）が飼育されており、この水槽本体２内の水４０は該水槽本体２内の後部側から濾過器２０（ケーシング２１）内の水循環ポンプ２２の吸引力によって吸い込み口２４（図４及び６参照）を介して濾過器２０内部に吸い込まれる。吸い込まれた水４０は、濾過器２０内の濾過材２３を通過することで濾過されて清浄な水、即ち濾過水４０ａとなる。そして、この濾過水４０ａは水循環ポンプ２２の動力によって濾過器２０の吐出口２５から吐出されて、水受け板１０の上面１１上における水槽本体２の後部側、即ち貯留凹部１２内へ供給される。供給された濾過水４０ａは、水受け板１０の貯留凹部１２内の底面１２ａで受けられて該貯留凹部１２内に一時的に溜められてから連続的に溝部１３内を前部側へ流れる。そして、溝部１３内を流れる濾過水４０ａが水受け板１０の前端縁１９から膜状に水槽本体２内の水面４１の前部上へ落下する。落下した濾過水４０ａは、水槽本体２内の水４０と混ざりながら濾過器２０内の水循環ポンプ２２の吸引力によって水槽本体２内の後部側へ吸い寄せられて再度、濾過器２０内に吸い込まれる。このように水槽本体２内の水４０は循環する。   In the aquarium fish tank 1 of the present embodiment, as shown in FIG. 3, ornamental fish (not shown) are bred in the water 40 in the aquarium body 2, and the water 40 in the aquarium body 2 is The water is sucked into the inside of the filter 20 through the suction port 24 (see FIGS. 4 and 6) by the suction force of the water circulation pump 22 in the filter 20 (casing 21) from the rear side in the water tank body 2. The sucked water 40 is filtered by passing through the filter medium 23 in the filter 20 to become clean water, that is, filtered water 40a. The filtered water 40 a is discharged from the discharge port 25 of the filter 20 by the power of the water circulation pump 22, and is supplied to the rear side of the water tank body 2 on the upper surface 11 of the water receiving plate 10, that is, into the storage recess 12. . The supplied filtered water 40a is received by the bottom surface 12a in the storage recess 12 of the water receiving plate 10 and temporarily stored in the storage recess 12, and then continuously flows in the groove 13 to the front side. And the filtered water 40a which flows through the inside of the groove part 13 falls from the front end edge 19 of the water receiving plate 10 onto the front part of the water surface 41 in the water tank body 2 in a film shape. The dropped filtered water 40a is sucked to the rear side in the water tank main body 2 by the suction force of the water circulation pump 22 in the filter 20 while being mixed with the water 40 in the water tank main body 2, and is sucked into the filter 20 again. Thus, the water 40 in the water tank main body 2 circulates.

而して、本実施形態の観賞魚用水槽１は次のような利点がある。   Thus, the aquarium fish tank 1 of the present embodiment has the following advantages.

水受け板１０は、該水受け板１０上（即ち水受け板１０の上面１１上）に供給された水４０（濾過水４０ａ）を略水平方向に受け流して水槽本体２内へ落下させるものであるから、水４０の空気との接触面積及び接触時間を増加させることができ、もって水４０に酸素を確実に取り込ませることができる。   The water receiving plate 10 receives water 40 (filtered water 40a) supplied on the water receiving plate 10 (that is, on the upper surface 11 of the water receiving plate 10) in a substantially horizontal direction and drops it into the water tank body 2. Therefore, the contact area and the contact time of the water 40 with the air can be increased, so that the water 40 can be surely incorporated with oxygen.

さらに、この水受け板１０は、水槽本体２内の水面４１に対して上側に離間した位置に水槽本体２内の水面４１の略全面を覆う状態に配置されているから、この観賞魚用水槽１は従来の水槽にはない新規な構造を有しており、趣向性が高められている。   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.

また、水受け板１０は、該水受け板１０上に供給された水４０（濾過水４０ａ）を水槽本体２内へ膜状に落下させるものであるから、水４０の空気との接触面積及び接触時間を更に増加させることができ、もって水４０に酸素を更に確実に取り込ませることができるし、趣向性を更に高めることができる。   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.

さらに、水受け板１０の上面１１に水４０（濾過水４０ａ）の流れ方向に延びた凸条１４が、複数個、水の流れ方向に対して略直交する方向に間隔をおいて並んで形成されていることにより、水受け板１０から落下する水４０をすだれ状乃至膜状に確実に実現することができる。   Further, a plurality of ridges 14 extending in the flow direction of the water 40 (filtered water 40a) are formed on the upper surface 11 of the water receiving plate 10 so as to be lined up in a direction substantially orthogonal to the flow direction of the water. By doing so, the water 40 falling from the water receiving plate 10 can be surely realized in the shape of interdigital or film.

また、水受け板１０に対して上側に離間した位置に、水槽本体２用の蓋体３０が配置されているので、水槽１の外側において空気中を漂う埃などが水受け板１０上に落下してここを流れる水４０（濾過水４０ａ）と一緒に水槽本体２内へ流入するのをこの蓋体３０によって防止することができる。   Further, since the lid body 30 for the water tank main body 2 is disposed at a position spaced apart from the water receiving plate 10, dust floating in the air outside the water tank 1 falls on the water receiving plate 10. Then, it is possible to prevent the lid 30 from flowing into the water tank body 2 together with the water 40 (filtered water 40a) flowing therethrough.

しかも、この蓋体３０は、水受け板１０に対して上側に離間した位置に配置されているので、水槽本体２の外側から水受け板１０と蓋体３０との間の隙間を介して水受け板１０上を流れる水４０や水受け板１０から落下する膜状の水４０を見ることができる。これにより、趣向性を更に高めることができる。   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, preference can be improved further.

その上、蓋体３０は、水槽本体２の上開口周縁２ａよりも高い位置に配置されているので、観賞魚に餌を与える際に、わざわざ蓋体３０を水槽本体２から取り外さなくても水槽本体２の上開口周縁２ａと蓋体３０との間の第１隙間５１から餌を水受け板１０上に投入すれば餌が水受け板１０上を流れる水４０（濾過水４０ａ）と一緒に水槽本体２内に落下するので、観賞魚への給餌を容易に行うことができる。さらに、水槽本体２内の水４０の交換を行う際には、蓋体３０を外さなくても第１隙間５１から水換えポンプ（図示せず）を水槽本体２内に差し込んで水４０の交換を行うことができるので、水４０の交換作業を容易に行うことができる。その上、水槽本体２内の水面４１に第１隙間５１から流入した外気が接触することにより水４０の熱が逃げるので、水温の上昇を抑制することができる。   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 the bait is put on the water receiving plate 10 from the first gap 51 between the upper opening peripheral edge 2a of the main body 2 and the lid 30, the water 40 flows along the water receiving plate 10 (filtered water 40a). Since it falls in the aquarium body 2, feeding to the aquarium fish can be performed easily. Further, when the water 40 in the water tank body 2 is replaced, the water 40 is replaced by inserting a water change pump (not shown) into the water tank body 2 from the first gap 51 without removing the lid 30. Therefore, the water 40 can be replaced easily. In addition, since the heat of the water 40 escapes when the outside air flowing in from the first gap 51 comes into contact with the water surface 41 in the water tank body 2, the rise in the water temperature can be suppressed.

しかも、蓋体３０の外周縁の前縁部３０ａと水槽本体２の上開口周縁２ａの前縁部２ｂとの間にも、第２隙間５２が水平方向に生じているので、水４０の交換作業を更に容易に行うことができるし、水温の上昇を確実に抑制することができるし、給餌作業を更に容易に行うことができる。しかも、蓋体３０を外さなくても、観賞魚が餌を食べている様子を水槽本体２内の水面４１の上側から第２隙間５２を通じて見ることができる。   And since the 2nd clearance gap 52 has arisen in the horizontal direction also between the front edge part 30a of the outer periphery of the cover body 30 and the front edge part 2b of the upper opening periphery 2a of the water tank main body 2, replacement | exchange of water 40 The work can be performed more easily, the rise in the water temperature can be reliably suppressed, and the feeding work can be performed more easily. Moreover, it is possible to see through the second gap 52 from above the water surface 41 in the aquarium body 2 that the aquarium fish is eating food without removing the lid 30.

また、水受け板１０は光透性を有するものであり、この水受け板１０に対して上側に離間した位置（本実施形態では蓋体３０の内部）に照明具３１が配置されているので、水受け板１０の上側から照明具３１により水槽本体２の内側に向けて照明をすると、その照明光が水受け板１０上を流れる水４０及び水受け板１０を順次透過する。そのため、水槽本体２内の水４０を照明することができるし、更には、水受け板１０上を流れる水４０によって照明光が揺らぐので、照明効果を向上させることができる。   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.

また、水槽本体２内の後部として、水槽本体２内における後板５の上部に形成された濾過器収容空間６内には、水槽本体２内の水４０を水槽本体２の後部側から吸い込んで濾過する濾過器２０が配置されており、水受け板１０は、該水受け板１０上に供給される水４０として、濾過器２０により濾過された濾過水４０ａを水受け板１０上における水槽本体２の後部側から前部側に受け流して水受け板１０の前端縁１９から水槽本体２内の水面４１の前部上へ落下させるものであるから、上述したように、水槽本体２内の水４０は循環するようになる。ここで、水受け板１０の前端縁１９から落下する濾過水４０ａの落下位置は水槽本体２内の前部であり、一方、濾過器２０により吸い込まれる水槽本体２内の水４０の吸い込み位置（即ち濾過器２０の吸い込み口２４の位置）は水槽本体２内の後端部であるから、落下位置と吸い込み位置との距離は長い。したがって、水槽本体２内に落下した濾過水４０ａがその落下位置から吸い込み位置に到達するまでの間に、水槽本体２内の水４０の略全部が濾過器２０により吸い込まれて濾過されることになるため、水槽本体２内の水４０に対して効率良く濾過することができるし、更に、水槽本体２内の水４０に対して酸素をより一層確実に取り込ませることができる。   Further, 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 in the upper part of the rear plate 5 in the water tank body 2 as the rear part in the water tank body 2. A filter 20 for filtering is disposed, and the water receiving plate 10 is a water tank main body on the water receiving plate 10 with the filtered water 40a filtered by the filter 20 as the water 40 supplied onto the water receiving plate 10. 2 from the rear side to the front side and dropped from the front edge 19 of the water receiving plate 10 onto the front part of the water surface 41 in the water tank body 2, as described above, the water in the water tank body 2 40 will circulate. 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.

図８は、上記実施形態の観賞魚用水槽１に用いられた水受け板１０の一変形形態を説明するための図である。同図において、１０Ａは本変形形態の水受け板である。以下、本変形形態の水受け板１０Ａの構成について上記実施形態の水受け板１０との相異点を中心に説明する。   FIG. 8 is a view for explaining a variation of the water receiving plate 10 used in the aquarium fish tank 1 of the above embodiment. In the same figure, 10A is the water receiving plate of this modification. Hereinafter, the configuration of the water receiving plate 10A of the present modified embodiment will be described focusing on the differences from the water receiving plate 10 of the above embodiment.

本変形形態の水受け板１０Ａでは、水４０（濾過水４０ａ）は、その上面１１上の全面に亘って後部側から前部側へ流れて水受け板１０Ａの前端縁１９から膜状に水槽本体２内の水面４１の前部上に落下するものである。さらに、この水受け板１０Ａの上面１１には、多数の花びらや葉を模した装飾模様１７Ａが略全面に亘って刻設されており、これにより、水受け板１０Ａの上面１１が水の流れ方向において凹凸状に形成されている。   In the water receiving plate 10A of the present modified embodiment, the water 40 (filtrated water 40a) flows from the rear side to the front side over the entire surface of the upper surface 11 to form a water tank in the form of a film from the front edge 19 of the water receiving plate 10A. It falls on the front part of the water surface 41 in the main body 2. Furthermore, a decorative pattern 17A imitating many petals and leaves is engraved over the entire upper surface 11 of the water receiving plate 10A, whereby the upper surface 11 of the water receiving plate 10A flows into the water. It is formed in an uneven shape in the direction.

本変形形態の水受け板１０Ａによれば、水受け板１０Ａの上面１１が水の流れ方向に対して凹凸状に形成されているので、水受け板１０Ａの上面１１上を流れる水４０（濾過水４０ａ）が微細な凹凸によって乱され、これにより水４０に酸素を更に一層確実に取り込ませることができる。しかも、水受け板１０Ａは光透性を有するものであるから、水受け板１０Ａの上面１１上を流れる水４０が凹凸によって乱されることで照明具３１からの照明光が更に揺らぐので、照明効果を更に向上させることができる。   According to the water receiving plate 10A of the present modified embodiment, the upper surface 11 of the water receiving plate 10A is formed in an uneven shape with respect to the direction of water flow. The water 40a) is disturbed by the fine irregularities, which allows the water 40 to take in oxygen even more reliably. In addition, since the water receiving plate 10A is light transmissive, the illumination light from the illuminating device 31 is further swayed by the water 40 flowing on the upper surface 11 of the water receiving plate 10A being disturbed by the unevenness. The effect can be further improved.

なお本発明では、上記実施形態の水受け板１０の上面１１としての貯留凹部１２の底面１２ａ及び溝部１３の底面１３ａに、本変形形態の水受け板１０Ａのように装飾模様１７Ａが刻設されることによって、これらの底面１２ａ、１３ａが水の流れ方向において凹凸状に形成されていても良く、この場合には、上記実施形態の水受け板１０のよる効果に加えて本変形形態の水受け板１０Ａによる効果が付与されるものとなる。   In the present invention, the decorative pattern 17A is engraved on the bottom surface 12a of the storage recess 12 as the top surface 11 of the water receiving plate 10 of the above embodiment and the bottom surface 13a of the groove 13 like the water receiving plate 10A of the present modified embodiment. Accordingly, the bottom surfaces 12a and 13a may be formed in an uneven shape in the water flow direction. In this case, in addition to the effect of the water receiving plate 10 of the above-described embodiment, The effect by 10 A of receiving plates will be provided.

以上で本発明の実施形態を説明したが、本発明は上記実施形態及び変形形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内で様々に変更可能であることは言うまでもない。   Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and modifications, and it goes without saying that various modifications can be made without departing from the scope of the present invention.

本発明は鑑賞魚水槽に利用可能である。   The present invention is applicable to an appreciation fish tank.
