[0008] An aquarium device according to one embodiment will be described below with reference to Figures 1 to 11. Note that in each figure (as well as Figure 12), the dimensional ratios in the drawing do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match either.

[0009] FIG. 1 is a perspective view of an aquarium device 1 according to this embodiment, and FIG. 2 is a perspective view showing a state in which a filter tank 3 of the aquarium device 1 according to this embodiment is pulled out.

[0010] As shown in Figures 1 and 2, the aquarium device 1 according to this embodiment includes an aquarium 2 for raising living organisms, a filter tank 3 for filtering water drained from the aquarium 2, a storage unit 4 for storing the filter tank 3 in a removable manner, and a pump 5 for returning the water filtered by the filter tank 3 to the aquarium 2. In this embodiment, the aquarium device 1 further includes an aquarium lid 6 for covering the aquarium 2. Living organisms include ornamental fish such as tropical fish and ornamental plants such as aquatic plants. In Figure 2, the filter tank 3 can be removed after a water supply unit 8 (water supply pipe 81), which will be described later, is removed from the pump 5.

[0011] Fig. 3 is a perspective view showing the aquarium device 1 according to this embodiment with the aquarium lid 6 removed. Fig. 4 is a plan view showing the aquarium device 1 according to this embodiment with the aquarium lid 6 removed.

[0012] As shown in Figures 3 and 4, the water tank 2 has a front wall 21, a pair of side walls 22, 22, a rear wall 23, and a bottom wall 24 (see Figure 4). The front wall 21, side walls 22, and rear wall 23 are collectively referred to as peripheral wall 20. In this embodiment, the water tank 2 is formed in a square shape when viewed from above, but is not limited to this. For example, the water tank 2 may be formed in a rectangular or circular shape when viewed from above.

[0013] In this embodiment, the water tank 2 is made of glass, but is not limited to this. By making the water tank 2 out of glass, it is possible to prevent the water tank 2 from being scratched. Note that the water tank 2 may also be made of, for example, a transparent resin.

[0014] A sealant (not shown) is preferably applied to the entire upper end surface of the peripheral wall 20 of the water tub 2 (or only a portion of it). This prevents the water tub lid 6 from slipping on the peripheral wall 20. It also prevents the water tub lid 6 from being damaged by a collision with the peripheral wall 20 when the water tub lid 6 is placed on the surface. Examples of sealants include silicone-based sealants, modified silicone-based sealants, polyurethane-based sealants, and polysulfide-based sealants.

[0015] The aquarium 2 is provided with an aquarium partition 25 that divides the interior of the aquarium 2. The aquarium partition 25 divides the aquarium 2 into a first area X1 for cultivating organisms and a second area X2 in which the drainage section 7, water supply section 8, etc., which will be described later, are arranged. In the second area X2, in addition to the drainage section 7 and water supply section 8, a heater (not shown), etc., are arranged.

[0016] The aquarium divider 25 is formed in a substantially U-shape when viewed from above. From the viewpoint of making the second area X2 difficult to see, the aquarium divider 25 is preferably formed of a colored material. The aquarium divider 25 has a plurality of communication holes 251 that communicate between the first area X1 and the second area X2, and a pipe attachment part 252 for attaching the water supply part 8. The width of the communication holes 251 is preferably smaller than the width of the living creatures. The pipe attachment part 252 is a notch provided at the upper end part of the aquarium divider 25.

[0017] Figure 5 is a cross-sectional view taken along line VV in Figure 4. As shown in Figure 5, water tub 2 has protrusion 26 that extends in the vertical direction and protrudes inward of water tub 2, and water tub divider 25 has a pair of notches 253, 253 for attachment to water tub 2. Protrusion 26 is fixed to side wall 22 of water tub 2, and notch 253 is located below the part of water tub 2 that faces side wall 22. Water tub divider 25 can be attached to water tub 2 by fitting notch 253 onto protrusion 26.

[0018] As shown in Figure 1, the water tub lid 6 is formed in substantially the same shape as the water tub 2 when viewed from above. In this embodiment, the water tub lid 6 is formed in a square shape when viewed from above, but is not limited to this. The water tub lid 6 includes a first plate 61 disposed on the first area X1 (see Figures 3 and 4), a second plate 62 disposed on the second area X2 (see Figures 3 and 4), and a hinge portion 63 that rotatably connects the first plate 61 and the second plate 62. The rear surface of the second plate 62 is located forward of the rear surface (rear wall 23) of the water tub 2.

[0019] The hinge portion 63 is formed of an elastic material and connects the opposing side surfaces of the first plate 61 and the second plate 62. Examples of elastic materials include silicone-based sealants, modified silicone-based sealants, polyurethane-based sealants, and polysulfide-based sealants. From the perspective of improving the appearance of the aquarium lid 6, it is preferable that the hinge portion 63 be substantially the same color as the first plate 61 and the second plate 62.

[0020] Fig. 6 is a rear view of the aquarium apparatus 1 according to this embodiment. As shown in Fig. 6, it is preferable to provide a gap G1 between the rear wall 23 of the aquarium 2 and the aquarium lid 6. This allows cables for devices (such as a heater) installed inside the aquarium 2 to be passed through the gap G1. In this embodiment, the gap G1 between the rear wall 23 of the aquarium 2 and the aquarium lid 6 is 7 mm, but is not limited to this.

[0021] As shown in Figures 3 to 5, the aquarium device 1 is equipped with a drain unit 7 that can drain water from the aquarium 2. The drain unit 7 has at least one drain pipe. In this embodiment, the drain unit 7 has a first drain pipe 71 and a second drain pipe 72. With this configuration, even if one drain pipe becomes clogged, water can be drained from the other drain pipe, preventing the water from overflowing from the aquarium 2. Note that the drain unit 7 may have, for example, three or more drain pipes, or may have only one drain pipe.

[0022] The first drain pipe 71 and the second drain pipe 72 are arranged vertically in the second region X2 of the aquarium 2. In this embodiment, the first drain pipe 71 and the second drain pipe 72 are straight pipes (without bends) made of resin, but are not limited to this. The upper end surface of the first drain pipe 71 is lower than the upper end surface of the second drain pipe 72. This allows water in the aquarium 2 to be drained from the first drain pipe 71 under normal conditions.

[0023] The difference H1 (see FIG. 5) in the vertical direction between the upper end surfaces of the first drain pipe 71 and the second drain pipe 72 is preferably 5 to 20 mm. By making the difference H1 5 mm or more, it is possible to prevent water from being discharged from the second drain pipe 72 under normal conditions, and by making the difference H1 20 mm or less, it is possible to prevent the aquarium 2 from becoming too large. In this embodiment, the difference H1 is 7 mm, but is not limited to this.

[0024] The drainage section 7 is equipped with a pipe fixing member 73 for fixing the first drainage pipe 71 and the second drainage pipe 72 to the bottom wall 24 of the aquarium 2. It is preferable that the pipe fixing member 73 protrudes below the bottom wall 24 of the aquarium 2. This increases the fixing strength between the pipe fixing member 73 and the bottom wall 24. The first drainage pipe 71 and the second drainage pipe 72 may also be fixed directly to the bottom wall 24 of the aquarium 2.

[0025] Aquarium device 1 is equipped with a water supply unit 8 for returning water discharged from pump 5 (see FIG. 5) to aquarium 2. The upper end position of water supply unit 8 is preferably located higher than the upper end faces of drain pipes 71 and 72 (i.e., above the water surface in aquarium 2) from the viewpoint of facilitating attachment and detachment to and from discharge pipe 51, which will be described later.

[0026] The water supply unit 8 is equipped with a water supply pipe 81 for returning water discharged from the pump 5 to the water tank 2. In this embodiment, the water supply pipe 81 is a straight pipe (without bends) made of resin, and is detachable from the discharge pipe 51 when the filter tank 3 is housed in the housing unit 4. The water supply pipe 81 is inserted into the second drain pipe 72 and is arranged substantially coaxially with the second drain pipe 72 and the discharge pipe 51. "Substantially coaxial" not only includes the respective axes being coaxial, but also includes a deviation of 5 mm or less between the respective axes. Note that the water supply pipe 81 is not limited to the above.

[0027] It is preferable to provide a gap G2 of 1 mm to 5 mm on one side between the water supply pipe 81 and the second drain pipe 72. By making the gap G2 1 mm or more, the drainage performance of the second drain pipe 72 can be ensured, and by making the gap G2 5 mm or less, the water supply pipe 81 can be easily connected to the discharge pipe 51 along the second drain pipe 72. In this embodiment, the gap G2 is 2.25 mm, but is not limited to this.

[0028] In this embodiment, water supply unit 8 is equipped with an adjustment unit 82 that can adjust the water supply direction. Adjustment unit 82 is equipped with a swiveling nozzle 821 and an L-shaped pipe 822. Adjustment unit 82 is attached to pipe attachment part 252 with nozzle 821 in a swiveling state, and supplies water sent from water supply pipe 81 to first area X1. Note that water supply unit 8 may not be equipped with adjustment unit 82, for example, and water supply pipe 81 may be an L-shaped pipe with an upper end bent toward first area X1.

[0029] 5 and 6, the storage section 4 includes a pair of side walls 41, 41, an upper wall 42, and a bottom wall 43. In this embodiment, the storage section 4 is open on the front and rear sides. Note that the storage section 4 may also be configured to further include a rear wall and be open only on the front side, for example.

[0030] The storage unit 4 is disposed below (directly below) the water tank 2. It is preferable that the outer surfaces of the side wall 41 of the storage unit 4 and the side wall 22 of the water tank 2 are substantially flush. "Substantially flush" not only means that the surfaces are flush, but also includes a step of 5 mm or less. In this embodiment, the side wall 41 of the storage unit 4 is made of glass and is formed integrally with the side wall 22 of the water tank 2. The top wall 42 of the storage unit 4 also serves as the bottom wall 24 of the water tank 2. However, the side wall 41 and top wall 42 of the storage unit 4 are not limited to those described above.

[0031] The bottom wall 43 of the storage section 4 has fitting grooves 431 (see FIG. 5) into which the side walls 41 of the storage section 4 can be fitted. This makes it easy to fix the bottom wall 43 and the side walls 41 together. The fitting grooves 431 are disposed on the upper surface of the bottom wall 43 and extend in the front-to-rear direction. The fitting grooves 431 are disposed on both sides of the bottom wall 43. It is preferable that the fitting grooves 431 are chamfered to make it easier to fit the side walls 41 into them.

[0032] The bottom wall 43 of the storage section 4 is formed to have a shape that is slightly larger than the water tank 2 when viewed from above. In this embodiment, the bottom wall 43 is made of resin, which makes it easy to form the fitting grooves 431 and the rails 44 described below.

[0033] 5, the pump 5 includes a discharge pipe 51. The discharge pipe 51 is preferably arranged in the vertical direction and positioned so as to overlap the second drain pipe 72 in a top view. This makes it easy to connect the water supply pipe 81 and the discharge pipe 51.

[0034] The filtration tank 3 is disposed below (directly below) the aquarium 2. This allows the pipe paths of the drainage section 7 and the water supply section 8 to be short, allowing the aquarium device 1 to be made compact.

[0035] Fig. 7 is a plan view of the filter tank 3 in this embodiment, and Fig. 8 is a bottom view of the filter tank 3 in this embodiment. As shown in Fig. 7 and Fig. 8, the filter tank 3 in this embodiment is formed in a substantially square shape when viewed from above and can be pulled out in the forward direction (see Fig. 2), but is not limited to this. For example, the filter tank 3 may be pullable in both the forward and backward directions.

[0036] The filter tank 3 includes a front wall 31, a pair of side walls 32, 32, a rear wall 33, and a bottom wall 34. In this embodiment, the front wall 31 (excluding a second front wall 312, which will be described later), the side wall 32, the rear wall 33, and the bottom wall 34 are integrally formed from resin. This configuration makes it possible to omit waterproofing and prevent water leakage from the filter tank 3 due to manufacturing defects. Furthermore, the portion that comes into contact with the storage unit 4 can be made of resin, which prevents scratches on the glass portion of the storage unit 4 when the filter tank 3 is pulled out. Furthermore, the filter tank 3 can be made lighter, making it easier to clean.

[0037] The front wall portion 31 includes a first front wall 311 that comes into contact with water and a second front wall 312 that does not come into contact with water. The second front wall 312 is disposed forward of the first front wall 311, and a space (gap G3) is provided between the first front wall 311 and the second front wall 312. This configuration makes it difficult for external light to reach areas behind the first front wall 311, making it difficult to see inside the filtration tank 3. This prevents the aesthetic appearance of the aquarium device 1 from being impaired. Furthermore, by making the second front wall 312 non-contact with water, it is possible to make it difficult to see moss and the like that has grown on the first front wall 311 from outside the filtration tank 3. Note that the front wall portion 31 may be configured to include only the first front wall 311, for example.

[0038] The gap G3 between the first front wall 311 and the second front wall 312 is preferably 15 mm to 25 mm. By making the gap G3 15 mm or more, it is possible to insert part of a finger into the gap G3, making it easier to clean the gap G3. By making the gap G3 25 mm or less, the capacity of the filtration tank 3 can be ensured. In this embodiment, the gap G3 is 20 mm, but is not limited to this.

[0039] The first front wall 311 and the second front wall 312 are arranged to be substantially parallel to each other. "Substantially parallel" does not only mean that the walls are parallel to each other, but also means that the angle formed by the walls is 5 degrees or less.

[0040] In this embodiment, the second front wall 312 is made of glass. With this configuration, the second front wall 312, the aquarium 2, and the side wall 41 of the storage section 4 can be made of the same material, and the parts visible from the front of the aquarium device 1 can be made of glass in a uniform manner. This gives the aquarium device 1 a unified appearance.

[0041] The front wall portion 31 includes a first protruding portion 313 that protrudes forward from the first front wall 311, and a second protruding portion 314 that protrudes from the front end portion of the first protruding portion 313. An upper portion of the second protruding portion 314 protrudes inward (downward), and a side portion of the second protruding portion 314 protrudes outward in the left-right direction.

[0042] Second front wall 312 is fixed (for example, glued) to the front surface of second protruding portion 314. By providing second protruding portion 314, the fixing surface of second front wall 312 can be increased compared to when second front wall 312 is fixed to the front end of first protruding portion 313, and the fixing strength of second front wall 312 can be ensured.

[0043] As shown in Figure 6, the gap G5 between the rear wall 33 of the filter tank 3 and the bottom wall 24 of the water tank 2 (the upper wall 42 of the storage section 4) is preferably 5 mm to 10 mm. By making the gap G5 5 mm or more, cables for a pump or the like can be passed through, and by making the gap G5 10 mm or less, it is possible to prevent outside air from entering the filter tank 3. In this embodiment, the gap G5 is 7.5 mm, and is constant across the left and right sides of the rear wall 33. This makes it possible to prevent contact between the pipe fixing member 73 and the rear wall 33 when the filter tank 3 is pulled out.

[0044] 5 and 6, the storage unit 4 is provided with rails 44 for pulling out (sliding) the filtration tank 3. In this embodiment, two rails 44 are arranged on the bottom wall 43 of the storage unit 4, but this is not limited to this. For example, the rails 44 may be arranged on the side wall 41 of the storage unit 4.

[0045] As shown in FIGS. 6 and 8 , the filter tank 3 includes a guide groove 39 that can be fitted onto the rail 44. The guide groove 39 includes a guide portion 391 that facilitates alignment with the rail 44. The guide portion 391 is disposed behind the guide groove 39 and is formed to widen toward the rear. In this embodiment, the guide portion 391 is formed in a triangular shape when viewed from above (or from the bottom), but this is not limiting. For example, the guide portion 391 may be formed in a substantially U-shape when viewed from above (or from the bottom). Furthermore, the guide groove 39 is disposed on the bottom wall 34 of the filter tank 3, but this is not limiting. For example, the guide groove 39 may be disposed on the side wall 32 of the filter tank 3.

[0046] As shown in Fig. 7, the filter tank 3 is provided with a filter tank divider 35 that divides the interior of the filter tank 3 into a plurality of regions. In this embodiment, the filter tank divider 35 divides the interior of the filter tank 3 into a pre-filtration region X3 that is located below (directly below) the first drain pipe 71 (see Fig. 5), a filter medium region X4 in which a filter medium is located, and a post-filtration region X5 in which a pump 5 is located. Note that the filter tank 3 may not be provided with the filter tank divider 35, for example, and the pre-filtration region X3 and the filter medium region X4 may not be separated from each other.

[0047] The filter material is not particularly limited as long as it can pass water and has the function of purifying water. Examples of filter materials include wool, sponge, ceramic, activated carbon, zeolite, gravel, sand, and coral.

[0048] The filter tank partition 35 includes a first partition member 351 that separates the regions X3 to X5, and a second partition member 352 that separates the filter region X4 into a first filter region X41 and a second filter region X42. In this embodiment, the first partition member 351 is formed in a T-shape when viewed from above, and the second partition member 352 is formed in an I-shape when viewed from above. The first partition member 351 and the second partition member 352 are formed of resin.

[0049] By providing the second partition member 352, it is possible to prevent water in the filter tank 3 from flowing into the post-filtration region X5 before passing through the filter material, thereby improving the filtering capacity of the filter tank 3. The filter tank divider 35 may be configured without the second partition member 352. The first filter material region X41 and the second filter material region X42 may be provided with the same filter material, or different filter materials. Furthermore, a filter material may be provided in only one of the first filter material region X41 and the second filter material region X42.

[0050] Fig. 9 is a cross-sectional view taken along line IX-IX in Fig. 4. As shown in Fig. 9, the first partition member 351 has a plurality of first communication holes 351a that communicate between the pre-filtration region X3 and the filter medium region X4, and a plurality of second communication holes 351b that communicate between the filter medium region X4 and the post-filtration region X5.

[0051] Figure 10 is a cross-sectional view taken along line XX in Figure 4. As shown in Figure 10, the second partition member 352 has a plurality of third communication holes 352a that connect the first filter medium region X41 and the second filter medium region X42. The third communication holes 352a are preferably located away from the pre-filtration region X3 and the post-filtration region X5 (see Figure 7). This prevents water in the filter tank 3 from flowing into the post-filtration region X5 before passing through the filter medium, thereby improving the filtering capacity of the filter tank 3.

[0052] 7 and 9, each side wall 32 of the filtration tank 3 has a first groove 321 into which the first partition member 351 can be inserted. The first groove 321 extends in the vertical direction, and the first grooves 321 are arranged inside the filtration tank 3 so as to face each other.

[0053] 7 and 10, the front wall 31 of the filtration tank 3 includes a second groove 315 into which the second partition member 352 can be inserted, and the first partition member 351 includes a third groove 351c into which the second partition member 352 can be inserted. The second groove 315 extends in the vertical direction and is disposed on the rear side (inside) of the first front wall 311. The third groove 351c extends in the vertical direction and is disposed in a position facing the second groove 315 (in front of the first partition member 351). In this embodiment, the second groove 315 and the third groove 351c have a larger groove width than the first groove 321.

[0054] The filter tank 3 is equipped with a water receiving member 38 having a water receiving surface 381 that receives water drained from the first drain pipe 71 within the filter tank 3. The water receiving member 38 is disposed in the pre-filtration region X3 of the filter tank 3. That is, the water receiving member 38 is disposed below (directly below) the first drain pipe 71. In this embodiment, the water receiving member 38 is a sponge, but is not limited to this. For example, the water receiving member 38 may be made of wool or the like. The water receiving member 38 is disposed on a protrusion 341 provided on the bottom wall 34 of the filter tank 3.

[0055] The water receiving surface 381 is a surface that slopes downward toward the inside of the filter tank 3. With this configuration, water drained into the filter tank 3 is received by the water receiving surface 381, thereby preventing the water from splashing out of the filter tank 3. It is preferable that the water receiving surface 381 be in contact with the upper wall 42 of the storage section 4 (the bottom wall 24 of the water tank 2).

[0056] As shown in FIGS. 5 and 7, the filter tank 3 is provided with a first restricting portion 36 for restricting the position of the discharge pipe 51. The first restricting portion 36 restricts the movement of the discharge pipe 51 so that it does not move at least in the front-to-back and left-to-right directions. In this embodiment, the first restricting portion 36 is a plate member made of resin, and is integrally formed with the first partition member 351. The first restricting portion 36 is disposed along a horizontal plane. As a result, by removing the first partition member 351, the restriction on the pump 5 by the first restricting portion 36 is released, and the pump 5 can be easily removed. Note that the first restricting portion 36 may be separate from the first partition member 351.

[0057] The first restricting portion 36 has a restricting hole 361 for restricting the position of the discharge pipe 51. A gap G6 between the restricting hole 361 and the discharge pipe 51 is preferably 0.2 mm to 2 mm on one side. In this embodiment, the gap G6 is 0.5 mm on one side, but is not limited to this.

[0058] As shown in FIG. 7, the first restricting portion 36 in this embodiment has a plurality of fourth communication holes 362 that connect the upper and lower sides of the first restricting portion 36, and a notch 363 for passing a cable (not shown) of the pump 5 through, but is not limited to this.

[0059] Fig. 11 is a plan view showing the state in which the filter tank partition 35 of Fig. 7 has been removed. As shown in Fig. 11, the filter tank 3 preferably has a second limiting portion 37 that limits the movement of the lower side of the pump 5. The second limiting portion 37 is a plurality of protrusions arranged to surround the periphery of the pump 5. The second limiting portion 37 is arranged on the bottom wall 34 of the filter tank 3.

[0060] As shown in Figure 10, a gap G4 between the front wall portion 31 (second front wall 312) of the filtration tank 3 and the bottom wall 24 of the water tank 2 (top wall 42 of the storage section 4) is preferably 5 mm or less. In this embodiment, the gap G4 is 2 mm, but is not limited to this. It is preferable that the second front wall 312 is substantially flush with the front wall 21 of the water tank 2.

[0061] When housed in the housing section 4, both side surfaces of the second front wall 312 are positioned forward of the side walls 41 of the housing section 4. This allows the filter tank 3 to be pulled out by grasping both side surfaces of the second front wall 312, eliminating the need for handles for pulling out the filter tank 3. This prevents the aesthetic appearance of the aquarium device 1 from being marred by providing handles.

[0062] [1] As described above, the aquarium device 1 of this embodiment comprises an aquarium 2 for raising living organisms, a filtration tank 3 arranged below the aquarium 2 for filtering water drained from the aquarium 2, a storage section 4 for storing the filtration tank 3 so that it can be pulled out, and a pump 5 for returning the water filtered in the filtration tank 3 to the aquarium 2, with the pump 5 arranged inside the filtration tank 3.

[0063] According to this configuration, by disposing the pump 5 inside the filter tank 3, the pump 5 can be pulled out together with the filter tank 3. This makes cleaning and replacement of the pump 5 easier and reduces the burden on the person cleaning. Furthermore, unlike aquarium tank devices in which the filter tank is pulled out upwards, the aquarium device 1 according to this embodiment does not cause water to spill out of the filter tank 3 when the filter tank 3 is pulled out. Furthermore, by disposing the pump 5 inside the filter tank 3, the aquarium device 1 can be made compact.

[0064] [2] Furthermore, in aquarium apparatus 1 according to the above [1], it is preferable that pump 5 is provided with discharge pipe 51, and filtration tank 3 is provided with first restricting portion 36 that restricts the position of discharge pipe 51.

[0065] This configuration can prevent the position of the discharge pipe 51 from shifting inside the filter tank 3. This makes it easy to attach and detach the discharge pipe 51 from the pipe (the water supply pipe 81 in this embodiment) when, for example, pulling out or storing the filter tank 3.

[0066] [3] Furthermore, it is preferable that the aquarium device 1 according to [1] or [2] above is provided with a water supply pipe 81 for returning the water discharged from the pump 5 to the aquarium 2, and that the water supply pipe 81 is detachable from the discharge pipe 51 when the filter tank 3 is housed in the housing section 4.

[0067] With this configuration, when the water supply pipe 81 is removed from the discharge pipe 51, the water present in the water supply pipe 81 can be discharged into the filter tank 3. This prevents the water in the water supply pipe 81 from splashing outside the filter tank 3 (aquarium device 1).

[0068] [4] Furthermore, it is preferable that the aquarium device 1 relating to any one of [1] to [3] above is provided with at least one or more drain pipes 71, 72 capable of draining water from the aquarium 2, the discharge pipe 51 is positioned so as to overlap one of the drain pipes 71, 72 (the second drain pipe 72) when viewed from above, and the water supply pipe 81 is inserted into one of the drain pipes (the second drain pipe 72).

[0069] With this configuration, the water supply pipe 81 can be connected to the discharge pipe 51 along the second drain pipe 72, making it easy to connect the water supply pipe 81 to the pump 5. In addition, the water supply pipe 81 can be pulled out from the discharge pipe 51 along the second drain pipe 72, making it easy to disconnect the water supply pipe 81 from the pump 5. As a result, the water supply pipe 81 can be easily attached and detached from the pump 5, making it easy to pull out the filter tank 3 and store the filter tank 3 in the storage section 4.

[0070] [5] Furthermore, it is preferable that the aquarium device 1 relating to any one of [1] to [4] above comprises a drain pipe (first drain pipe 71) capable of draining water from the aquarium 2, and a water receiving member 38 having a water receiving surface 381 that receives water drained from the drain pipe (first drain pipe 71) within the filtration tank 3, and that the water receiving surface 381 is inclined downward toward the inside of the filtration tank 3 and is in contact with the upper wall 42 of the storage section 4.

[0071] According to this configuration, by bringing the water receiving surface 381 into contact with the upper wall 42 of the storage section 4, it is possible to prevent water that hits the water receiving surface 381 from splashing out to the outside of the filter tank 3. In addition, when the filter tank 3 is pulled out, water dripping from the first drain pipe 71 can be wiped away, which prevents water from spilling into the storage section 4.

[0072] [6] Furthermore, in the aquarium device 1 according to any one of [1] to [5] above, it is preferable that the filtration tank 3 can be pulled out in the forward direction, and that the gap G4 between the front wall (second front wall 312) of the filtration tank 3 and the upper wall 42 of the storage section 4 is 5 mm or less.

[0073] This configuration can prevent external air from entering the filter tank 3, thereby reducing the temperature difference between the water in the filter tank 3 and the water in the aquarium 2. This can prevent condensation from forming on the bottom wall 24 of the aquarium 2.

[0074] The aquarium apparatus 1 is not limited to the configuration of the above-described embodiment, nor is it limited to the above-described effects. Furthermore, various modifications can be made to the aquarium apparatus 1 without departing from the spirit of the present invention. For example, it is possible to arbitrarily select one or more of the configurations, methods, etc. of the various modified examples described below and adopt them in the configurations, methods, etc. of the above-described embodiment.

[0075] (A) The rear wall 33 of the filter tank 3 may be configured to have a notch at the top for passing a cable through. This configuration can reduce the gap G5 between the bottom wall 34 of the filter tank 3 and the bottom wall 24 of the aquarium 2 (the upper wall 42 of the storage section 4). This further prevents outside air from entering the filter tank 3, and further prevents condensation from forming on the bottom wall 24 of the aquarium 2.

[0076] (B) In this embodiment, the water supply pipe 81 is a straight pipe made of resin, but is not limited to this. For example, the water supply pipe 81 may be a hose having an excess length equal to or greater than the length of the filter tank 3 that is pulled out. This allows the filter tank 3 to be pulled out without pulling out the water supply pipe 81. In such a configuration, the water supply pipe 81 (hose) is arranged to pass through the outside of the aquarium device 1 (aquarium 2).

[0077] (C) In this embodiment, the drainage section 7 includes a first drain pipe 71 and a second drain pipe 72, and the water supply pipe 81 is inserted into the second drain pipe 72, but this is not limited to this. For example, as shown in FIG. 12, the drainage section 7 may include only the first drain pipe 71, and the water supply pipe 81 may be arranged in the third area X6 (not inserted into the drain pipe). The third area X6 is an area provided within the aquarium 2 into which water does not enter. The height of the wall 27 separating the third area X6 is the same as the height of the peripheral wall 20 of the aquarium 2, for example.

[0078] (D) In ​​this embodiment, the aquarium device 1 is configured to include one filter tank 3, but this is not limited to this. For example, the aquarium device 1 may be configured to include multiple filter tanks 3. In such a configuration, the multiple filter tanks 3 are arranged in a vertical direction, and the pump 5 is arranged in the lowest filter tank 3. [Explanation of symbols]
