JP-A-3-195434

  As described above, aquarium fish tanks often require a device for taking oxygen into water. In addition, ornamental fish tanks are often installed as interiors in the interior, so that they are highly interesting.

  The present invention has been made in view of the above-described technical background, and an object of the present invention is to provide an aquarium for ornamental fish that is capable of reliably incorporating oxygen into water and that is rich in interest.

  The present invention provides the following means.

[1] A water receiving plate is disposed in a state of covering the substantially entire surface of the water surface at a position spaced upward from the water surface in the water tank body,
An aquarium for ornamental fish, wherein the water receiving plate receives water supplied on the water receiving plate in a substantially horizontal direction and drops it into the main body of the aquarium.

  [2] The aquarium for aquarium fish according to the preceding item 1, wherein the water receiving plate drops water supplied on the water receiving plate into a water-like or film shape into the water tank body.

  [3] On the upper surface of the water receiving plate, a plurality of ridges extending in the water flow direction are formed side by side in a direction substantially perpendicular to the water flow direction. The aquarium fish tank described.

  [4] The aquarium fish tank according to any one of the preceding items 1 to 3, wherein a lid for the aquarium body is disposed at a position spaced upward from the water receiving plate.

[5] The water receiving plate is light transmissive.
The aquarium for ornamental fish according to any one of the preceding items 1 to 4, wherein an illuminating device for illuminating toward the inside of the aquarium main body is disposed at a position spaced upward from the water receiving plate.

[6] A filter for sucking and filtering the water in the aquarium body from the rear side of the aquarium body is provided.
The water receiving plate receives, as water supplied on the water receiving plate, filtered water filtered by the filter from the rear side of the water tank body to the front side on the water receiving plate, and the front end of the water receiving plate. 6. The aquarium tank for ornamental fish according to any one of the preceding items 1 to 5, which is dropped from the edge to the front part in the aquarium body.

  [7] The aquarium fish tank according to any one of items 1 to 6, wherein the upper surface of the water receiving plate is formed in an uneven shape in the water flow direction.

  The present invention has the following effects.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

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.

  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.

  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.

  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.

  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. Has been placed.

  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.

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.

  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.

  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.

  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).

  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.

  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.

  Thus, the aquarium fish tank 1 of the present embodiment has the following advantages.

  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.

  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, 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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.
