Description

  For example, the present invention relates to an aquarium facility that is used when aquatic organisms such as ornamental fish and aquatic plants are cultivated while being cultivated in a general household.

  In addition to aquatic organisms such as ornamental fish in the aquarium, a general aquarium fish tank that is often used in homes, etc., is equipped with a filtration device for adjusting the water quality, water temperature, etc. to maintain the water quality at a predetermined quality or higher. Instruments such as a cooling / heating device are arranged. Such instruments are indispensable for maintaining a good breeding environment, but may be annoying for viewers and may impair aesthetics.

  Therefore, as shown in Patent Documents 1 and 2 below, an aquarium facility has been developed in which no equipment for maintaining water quality (for maintaining a breeding environment) is arranged in an ornamental aquarium. This aquarium equipment consists of a main aquarium as an ornamental aquarium where ornamental fish are bred, a sub aquarium as an instrument aquarium where water quality maintenance equipment is arranged, and a forward pipe and a return pipe connecting the two aquariums. And a circulation pump, and by driving the circulation pump, the water in the sub water tank is supplied to the main water tank via the forward pipe, and the water in the main water tank is returned to the sub water tank via the return pipe. ing. By circulating water between the two water tanks in this way, the water quality in the main water tank is favorably maintained without arranging instruments in the main water tank.

  The main water tank side recessed portion 21 is formed with an oval discharge port 4b and a suction port 5a, respectively, in plan view. The discharge port 4b functions as a discharge port for a later-described forward conduit 4, and the suction port 5a functions as a suction port for a later-described return conduit 5.

  The discharge port 4b has a shape corresponding to the shape of the discharge port 4b, and a discharge port closing lid 41 for closing the discharge port 4b in a watertight state is detachably mounted. The discharge port closing lid 41 is formed with a circular outflow hole 42 that allows water to flow.

  The suction port 5a has a shape corresponding to the shape of the suction port 5a, and a suction port closing lid 51 for closing the suction port 5a in a watertight state is detachably attached (openable and closable). . The suction port closing lid 51 is formed with a circular inflow hole 52 that allows water to flow.

  A circular suction port 4 a and a discharge port 5 b are formed in the sub water tank side recessed portion 31 of the base 1. The suction port 4 a functions as a suction port for the forward pipeline 4, and the discharge port 5 b functions as a discharge port for the return pipeline 5.

  FIG. 5 is a bottom view (back view) showing the base 1 of the water tank facility, and FIG. 6 is an exploded perspective view of the base 1 as seen from the back side. As shown in both figures, the back surface of the base 1 is provided with a forward conduit member 40 in a region from the forward conduit suction port 4a of the sub water tank 3 to the forward conduit discharge port 4b of the main water tank 2, A return line member 50 is provided in a region from the return line suction port 5 a of the water tank 2 to the return line discharge port 5 b of the sub water tank 3.

  As shown in FIGS. 6 to 8, the pipe members 40 and 50 are constituted by long synthetic resin long members having a groove shape with a substantially U-shaped cross section. The pipe members 40 and 50 are formed with an upper opening 61 opened upward, but a blocking wall is formed on both end faces in the length direction, and both end faces in the length direction are in the length direction. Each is blocked.

  Further, a sealing material filling groove 62 that is continuous along the peripheral edge portion is formed in the peripheral edge portion (upper end surface of the peripheral wall) of the upper opening 61 of the duct members 40 and 50. Further, a plurality of screwing pieces 63 are integrally formed on the outer peripheral edge portions of the pipe members 40 and 50 so as to protrude outwardly at appropriate intervals along the outer peripheral edge portion.

  On the other hand, on the back side (lower surface side) of the base 1, the ribs 12 are integrated so as to continuously protrude along the outer peripheral edge of the region where the pipe members 40 and 50 are installed. Is formed. The ribs 12 are formed corresponding to the sealing material filling grooves 62 of the duct members 40 and 50 and can be fitted into the sealing material filling grooves 62. Further, on the outer side of the rib 12 on the back surface side of the base 1, screwing portions 13 are integrally formed corresponding to the screwing pieces 63 of the pipe members 40 and 50, respectively.

  Then, the sealing material filling groove 62 of the pipe members 40 and 50 is filled with the paste-like or paste-like silicon-based sealing material 7, and the pipe members 40 and 50 with the sealing material are filled in the sealing material filling groove 62. It arrange | positions so that the rib 12 may fit. Further, with the pipe members 40 and 50 pressed against the base 1 side, screws 71 such as screws are passed through the screwing pieces 63 of the pipe members 40 and 50 and screwed to the screwing portions 13 of the base 1. As a result, the duct members 40 and 50 are fixed to the base 1. In this fixed state, the sealing material 7 is filled and disposed between the peripheral edge of the upper opening of the pipe members 40 and 50 and the upper plate 11 (rib 12) of the base 1, thereby achieving watertightness therebetween. In this state, the pipe members 40 and 50 are fixed to the base 1 in close contact.

  Here, in the present embodiment, the forward conduit 4 is formed by the forward conduit member 40 and the upper plate 11 of the base 1, and the return pipe is formed by the return conduit member 50 and the upper plate 11 of the base 1. A path 5 is formed.

  One end of the upper opening 61 of the forward duct member 40 is arranged corresponding to the discharge port 4b of the main water tank bottom surface 22 of the base 1, and the other end corresponds to the suction port 4a of the sub water tank bottom surface 32. Are arranged. Therefore, as described above, the suction port 4 a of the sub-water tank bottom surface 32 functions as the suction port of the forward pipeline 4, and the discharge port 4 b of the main water tank bottom surface 22 functions as the discharge port of the forward pipeline 4.

  Furthermore, one end of the upper opening 61 of the return pipe member 50 is disposed corresponding to the suction port 5a of the main water tank bottom surface 22 of the base 1, and the other end corresponds to the discharge port 5b of the sub water tank bottom surface 32. Are arranged. Therefore, as described above, the suction port 5 a on the bottom surface 22 of the main water tank functions as a suction port for the return pipe 5, and the discharge port 5 b on the bottom surface of the sub water tank 32 functions as a discharge port for the return pipe 5.

  As shown in FIGS. 1 and 2, the main water tank peripheral wall body 20 attached to the main water tank side recessed portion 21 in the base 1 constitutes four walls around the main water tank 2, and is a cylinder whose upper and lower ends are open. It is formed in a shape (square tube shape). The main water tank peripheral wall body 20 is made of a transparent glass plate or a synthetic resin plate, and has a horizontal plane shape (horizontal cross-sectional shape) corresponding to the plane shape of the main water tank side recessed portion 21. The lower end portion of the main water tank peripheral wall body 20 is fixed in a state of being fitted into the main water tank side recessed portion 21. A paste-like or paste-like silicon-based sealing material (not shown) is filled and applied between the lower end portion of the main water tank peripheral wall body 20 and the peripheral edge portion of the main water tank-side recessed portion 21, whereby the main water tank peripheral wall body 20. Is fixed to the base 1 in a watertight state.

  Further, a silicon-based sealing material 26 is applied and fixed to the upper end surface of the main water tank peripheral wall body 20 (upper peripheral edge of the upper end opening of the main water tank peripheral wall body 20). In FIG. 2, the application region of the sealing material 26 is indicated by hatching with hatched lines and dot patterns (the same applies to FIGS. 9 to 11 described later).

  A main water tank lid 25 made of a transparent glass plate or synthetic resin plate is provided at the upper end opening of the water tank peripheral wall body 20. The main water tank lid 25 is formed in a rectangular shape in plan view corresponding to the planar shape of the upper end opening of the main water tank peripheral wall body 20. The main water tank lid 25 is placed on the upper end surface of the main water tank peripheral wall body 20 via a sealing material 26, and the upper end opening of the main water tank peripheral wall body 20 is closed. Although the main water tank lid 25 is elastically adhered to the sealing material 26, it is not bonded and is not fixed. That is, if the main water tank lid 25 is lifted, it can be removed from the main water tank peripheral wall body 20 (sealing material 26), and thereby the upper end opening of the main water tank peripheral wall body 20 can be opened. Thus, the main water tank peripheral wall body 20 is configured such that the upper end opening thereof can be freely opened and closed by the main water tank lid 25.

  Here, in the present embodiment, the main water tank 2 as an ornamental water tank is formed by the main water tank peripheral wall body 20, the bottom surface of the main water tank-side recessed portion 21, and the main water tank lid 29.

  Moreover, the sub water tank surrounding wall body 30 attached to the sub water tank side recessed part 31 in the base 1 comprises the circumference | surroundings 4 wall of the sub water tank 3, and is formed in the cylinder shape (square cylinder shape) by which the upper and lower ends were open | released. Has been. The sub-aquarium peripheral wall body 30 is made of an opaque glass plate or a synthetic resin plate colored in black or the like, and has a horizontal plane shape (horizontal cross-sectional shape) corresponding to the plane shape of the sub-water tank side recessed portion 31. Have. The lower end portion of the sub water tank peripheral wall body 30 is fixed in a state of being fitted into the sub water tank side recessed portion 31. In addition, a paste-like or paste-like silicon-based sealing material (not shown) is filled and applied between the lower end portion of the sub-water tank peripheral wall body 30 and the peripheral edge portion of the sub-water tank-side recessed portion 31, thereby sub-water tank peripheral wall body 30. Is fixed to the base 1 in a watertight state. Here, in the present embodiment, the sub water tank 3 as an instrument water tank is formed by the sub water tank peripheral wall body 30 and the bottom surface of the sub water tank side recessed portion 31.

  In the present embodiment, the sub water tank 3 is not provided with a lid. However, as described later, in the present invention, the sub water tank 3 may be provided with a lid.

  As shown in FIGS. 1 to 4, in the bottom surface 22 of the main water tank 2, the discharge nozzle 23 is detachably attached to the outflow hole 42 of the discharge port closing lid 41, and the inflow hole 52 of the suction port blocking lid 51 is attached to the outflow hole 52. A strainer pipe (pipe with strainer) 24 is detachably attached. As a result, the water in the forward pipe 4 is discharged into the main water tank 2 through the discharge nozzle 23, and the water in the main water tank 2 is sucked into the return pipe 5 through the strainer pipe 24. ing. It should be noted that the components provided on the main water tank 2 side such as the discharge nozzle 23 and the strainer pipe 24 are preferably made of a transparent material so as not to stand out.

  Further, on the bottom surface 32 of the sub water tank 3, a strainer pipe (pipe with a strainer) 34 is detachably attached to the return pipe discharge port 5b, and the water in the return pipe 5 passes through the strainer pipe 34. 3 is now sucked into.

  Further, a discharge pump 15 as a circulation pump is installed on the bottom surface 32 of the sub water tank 3. The discharge port of the discharge pump 15 is disposed so as to be fitted into the outgoing pipe suction port 4 a in the bottom surface 32 of the sub water tank, and the suction port of the discharge pump 15 is disposed so as to open into the sub water tank 3. . Accordingly, the water in the sub water tank 3 is sucked into the discharge pump 15 and discharged into the forward conduit 4 through the forward conduit suction port 4a.

  Further, a filter (filtering device) 16 is disposed between the discharge pump 15 and the strainer pipe 34 in the sub water tank 3 so as to partition the both, and the air is sucked into the sub water tank 3 from the return pipe discharge port 5b. The water is filtered through the filter 16 and then discharged from the outgoing pipe suction port 4a by the discharge pump 15.

  In the water tank facility of the present embodiment configured as described above, when the discharge pump 15 is driven in a state where a predetermined amount of water is stored in the main water tank 2 and the sub water tank 3, the water in the sub water tank 3 is discharged to the discharge pump 15. And is discharged from the suction port 4a into the forward pipeline 4. The water discharged into the outgoing pipe 4 passes through the outgoing pipe 4, passes through the outlet hole 42 of the closing lid 41 provided in the outlet 4 b of the main water tank bottom 22, and enters the main water tank 2 from the discharge nozzle 23. Supplied.

  When water is thus supplied from the sub-water tank 3 into the main water tank 2, water of substantially the same amount as the supply amount is automatically returned from the main water tank 2 to the sub-water tank 3 via the return pipe 5. That is, the water in the main water tank 2 is sucked into the return pipe 5 through the strainer pipe 24 from the inflow hole 52 of the closing lid 51 provided in the suction port 5 a, and the water passes through the return pipe 5. The water is sucked into the sub water tank 3 through the strainer pipe 34 from the discharge port 5b of the bottom surface 32 of the sub water tank. The water sucked into the sub water tank 3 is filtered through the filter 16, and then sucked into the discharge pump 15 in the same manner as described above, and discharged into the forward conduit 4.

  By circulating water between the main water tank 2 and the sub water tank 3 in this way, the water quality in the main water tank 2 is maintained in a good state without arranging instruments such as a filter in the main water tank 2. be able to. Therefore, aquatic organisms such as ornamental fish can be bred in the main aquarium 2 under a good breeding environment. Furthermore, since a filter, a circulation pump, or the like that prevents the viewing is not disposed in the main water tank 2, a good aesthetic appearance can be obtained for the viewer.

  Further, in the water tank facility of the present embodiment, the discharge port 4b on the bottom surface 22 of the main water tank is closed by the discharge port closing lid 41, and water is discharged into the main water tank 2 from the outflow hole 42 formed in the closing lid 41. I am doing so. For this reason, since the opening area of the outflow hole 42 substantially functioning as the discharge port 4b can be reduced, the momentum of the water discharged from the outflow hole 42 into the main water tank 2 can be secured sufficiently strong. Therefore, the water discharged from the outflow hole 42 circulates in the main water tank 2 greatly and then is sucked in from the suction port 5a (inflow hole 52) of the return pipe 5, effectively preventing the occurrence of a shortcut. can do.

  Moreover, in the water tank facility of the present embodiment, since the discharge port closing lid 41 is detachably attached to the discharge port 4b on the bottom surface 22 of the main water tank, the entire area of the discharge port 4b is opened by removing the discharge port closing lid 41. As a result, the discharge port portion of the outgoing pipe 4 can be greatly opened. For this reason, by removing the discharge port obstruction | occlusion lid | cover 41, the discharge port periphery of the outward pipeline 4 can be cleaned without difficulty, and the maintenance check of the discharge port periphery can be performed reliably without difficulty.

  Furthermore, in the water tank facility of the present embodiment, the suction port 5a on the bottom surface 22 of the main water tank is closed by the suction port closing lid 51 with an inflow hole, so the opening of the inflow hole 52 that substantially functions as the suction port 5a. The area can be reduced, the inconvenience that the inflow hole 52 (suction port 5a) is conspicuous can be prevented, and the aesthetic appearance can be further improved. In addition, by removing the suction port closing lid 51, the entire area of the suction port 5a can be opened widely, so that the vicinity of the suction port of the return conduit 5 can be cleaned without difficulty in the same manner as described above, and maintenance inspection around the suction port can be performed. It can be done without difficulty.

  However, in the present invention, it is not always necessary to attach the closing lid 51 to the suction port 5a of the return pipe 5, and the relatively large suction port 5a may be left as it is on the bottom surface 22 of the main water tank. A plate-like strainer member may be directly attached so as to close the large suction port 5a.

  Further, in the water tank facility of the present embodiment, a groove-shaped shape is formed so as to bridge between the discharge port 4b on the main water tank 2 side and the suction port 4a on the sub water tank 3 side on the back surface side of the upper plate 11 of the base 1. The forward conduit member 40 is attached to form the forward conduit 4, and a groove-shaped return conduit member 50 is provided so as to bridge between the suction port 5a on the main water tank 2 side and the discharge port 5b on the sub water tank 3 side. Since the return pipe 5 is formed by attaching, the forward pipe 4 and the return pipe 5 can be formed simply by attaching the groove-shaped pipe members 40 and 50 to the back surface of the base 1. As a result, the entire aquarium facility can be manufactured easily and efficiently.

  Further, in the aquarium equipment of this embodiment, the silicon-based sealing material 7 is filled between the peripheral edge of the upper opening of the channel-shaped pipe members 40 and 50 and the upper plate back surface of the base 1, and the space therebetween is closely attached. Since they are fixed, it is possible to manufacture the forward pipeline 4 and the return pipeline 5 that are efficient in work and excellent in water tightness, and can reliably provide high-quality water tank equipment that does not leak water.

  Further, when the pipe members 40 and 50 are attached to the base 1, the sealing material 7 is applied to the peripheral edge of the upper opening of the pipe members 40 and 50, and then screwed on the outer peripheral edge of the pipe members 40 and 50. Since the piece 63 is screwed and fixed to the screwing portion 13 of the base 1 with the screw 71, the pipe members 40 and 50 are attached to the base 1 even in a state before the sealing material 7 is cured. It can be fixed in a stable state. Therefore, it is not necessary to leave until the sealing material 7 is cured, and the next manufacturing process can be performed as it is in the state before curing. Thus, since it can process continuously, without considering the hardening time of the sealing material 7, a water tank equipment can be assembled efficiently and in a short time, and production efficiency can be improved. In some cases, the sealant 7 can be shipped as a product even in a state before the sealant 7 is cured.

  In the present embodiment, the sealing material 26 is applied and cured on the upper end surface of the peripheral wall body 20 in the main water tank 2, and the main water tank lid 25 is placed on the upper end of the main water tank peripheral wall body 20 through the sealing material 26. Therefore, the main water tank lid 25 is placed in a stable state by being elastically adhered to the sealing material 26. Therefore, for example, even if a user or the like comes into contact with the main water tank lid 25, it is possible to prevent the main water tank cover 25 from being displaced with respect to the main water tank peripheral wall body 20.

  Moreover, in this embodiment, since the sealing material 26 is filled over the entire circumference between the main water tank peripheral wall body 20 and the main water tank lid 25, the airtightness of the main water tank 2 can be increased. For this reason, the reduction | decrease of the water by the evaporation of the water from the main water tank 2 side can be suppressed.

  Furthermore, in this embodiment, since the airtightness in the main water tank 2 is high, the water level in the main water tank 2 can be kept substantially constant without being affected by the water level change.

  Moreover, in this embodiment, the water leak from the clearance gap between the main water tank surrounding wall body 20 and the main water tank cover 25 can also be prevented effectively. That is, when the water in the main water tank 2 evaporates and adheres to the back surface (lower surface) of the main water tank lid 25, the moisture travels along the lower surface of the main water tank lid 25 and between the main water tank peripheral wall body 20 and the main water tank lid 25. There is a risk of leaking out of the water tank through the gap. Therefore, in the present embodiment, since the sealing material 26 is filled over the entire circumference between the main water tank peripheral wall body 20 and the main water tank lid 25, the moisture adhering to the back surface (lower surface) of the main water tank lid 25 is sealed. It is blocked by the material 26 and can be prevented from leaking out of the water tank through the gap between the main water tank peripheral wall body 20 and the main water tank lid 25.

  In addition, in the said embodiment, although the case where the sealing material 26 was apply | coated to the perimeter of the upper end surface in the main water tank surrounding wall body 20 was mentioned as an example, it was not restricted only to that, In this invention, in the main water tank surrounding wall body 20 It is sufficient that the sealing material 26 is applied to at least a part of the upper end surface. However, in the present invention, in order to ensure the stability of the main water tank lid 25, the sealing material 26 is placed at two or more positions spaced in the circumferential direction in the entire circumference of the upper end surface of the main water tank peripheral wall body 20. It is good to apply. For example, as shown in FIG. 9A, a sealing material 26 is applied to two opposing wall portions (front and rear walls or left and right walls) among the four wall portions of the main water tank peripheral wall body 20, and further FIG. As shown in b), the sealing material 26 may be applied to the four corner portions of the main water tank peripheral wall body 20. As described above, when the sealing material 26 is partially applied to the upper end surface of the main water tank peripheral wall body 40, the airtightness of the main water tank 2 is reduced. For example, when the water level is reduced due to evaporation or the like, the water level is reduced. It can be recognized immediately and can respond to the drop in water level without delay.

  Moreover, in the said embodiment, although the case where the sealing material 26 was apply | coated to the main water tank surrounding wall body 20 was demonstrated as an example, it was not restricted only to that, In this invention, the sealing material 26 is apply | coated to the main water tank lid | cover 25 side. May be fixed to the main water tank peripheral wall 20 side. When applying to the main water tank lid 25 side, for example, as shown in FIG. 10A, it is preferable to apply the sealing material 26 to the entire periphery (all four sides) of the outer peripheral edge portion on the lower surface of the main water tank cover 25. That is, also in this case, the same effect as the above embodiment can be obtained.

  However, in the present invention, when the sealing material 26 is applied to the main water tank lid 25 side, as shown in FIG. 10 (b), the sealing material 26 is applied to two opposing sides of the main water tank lid 25, or FIG. As shown in c), the sealing material 26 may be applied to the four corners of the main water tank lid 25.

  In the present invention, as shown in FIG. 11, a sub water tank lid 35 made of a transparent glass plate or a synthetic resin plate may be provided to be openable and closable at the upper end opening in the peripheral wall body 30 of the sub water tank 3. . In this case, as shown in the figure, the sealing material 26 may be applied to the upper end surface of the sub water tank peripheral wall body 30, or the sealing material 36 may be applied to the outer peripheral edge of the lower surface of the sub water tank lid 35. . Furthermore, the sealing material 36 may be filled in the entire circumference between the sub water tank peripheral wall body 30 and the sub water tank lid 35, or the sealing material 26 may be applied to a part of the entire circumference. Thus, when providing the sealing material 36 between the sub water tank surrounding wall body 30 and the sub water tank lid | cover 35, the sub water tank cover 35 passes the sealing material 36 via the sealing material 36 like the said embodiment. Because of the elastic contact, the sub water tank lid 35 can be disposed in a stable state, and displacement of the sub water tank peripheral wall body 30 can be prevented.

  Moreover, in the said embodiment, although the case where the horizontal cross section formed the rectangular main water tank 2 and sub water tank 3 was mentioned as an example, it demonstrated and it was not restricted only to that, In this invention, the main water tank 2 and the sub water tank 3 of The shape is not particularly limited. For example, the horizontal cross-sectional shapes of the main water tank 2 and the sub water tank 3 may be formed in a circular shape, an elliptical shape, an oval shape, a polygonal shape other than the above embodiment, or an irregular cross-sectional shape. Thus, even if the upper end openings of the water tank peripheral wall bodies 20 and 30 have a shape other than the rectangular shape, the sealing materials 26 and 36 are provided between the water tank peripheral wall bodies 20 and 30 and the water tank lids 25 and 35 in the same manner as described above. Moreover, the position shift with respect to the water tank surrounding wall bodies 20 and 30 of the water tank lids 25 and 35 can be prevented.

  Further, in the above embodiment, the main water tank 2 and the sub water tank 3 are formed in a cylindrical shape whose horizontal cross-sectional shape does not change regardless of the height position, but the present invention is not limited thereto. For example, in the present invention, as the main water tank and the sub water tank, the horizontal cross-sectional shape and size change depending on the height position, such as a cone shape, a truncated cone shape, a pyramid shape, a truncated pyramid shape, a drum shape, and a barrel shape. You may use it.

  Further, it is not necessary to form the main water tank 2 and the sub water tank 3 in the same shape as each other. For example, one water tank may have a circular cross section and the other water tank may have a rectangular cross section.

  Moreover, in the said embodiment, although the case where all the four surrounding walls of the front, back, left, and right of the main water tank 2 were formed transparently was described as an example, the present invention is not limited to this. For example, only one side wall may be formed transparently.

  Furthermore, in the present invention, the sub water tank 3 does not necessarily need to be formed opaque, and at least a part thereof may be formed transparently.

  Moreover, in the said embodiment, although the case where the filter 16 was arrange | positioned as an instrument for water quality maintenance in the sub aquarium 3 was mentioned as an example, the instrument for water quality maintenance was not restricted only to a filtration apparatus. . For example, appliances such as a heater and a cooler for adjusting the water temperature may be disposed in the sub water tank 3.

  The aquarium equipment of the present invention can be suitably used when watching aquatic organisms such as ornamental fish and aquatic plants while rearing and cultivating them in ordinary households.
