Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present disclosure is to provide a filter with improved ease of cleaning.

Means for Solving the Problems

[0005] The filter of the present disclosure is a filter detachably attachable to an aquarium, and includes a filtration unit at least partially submerged in breeding water inside the aquarium when attached to the aquarium, wherein at least a portion of the front wall of the filtration unit that is submerged in the breeding water is formed of glass.

[0006] According to such a configuration, by forming the portion of the front wall of the filtration unit that is submerged in the breeding water from glass, dirt such as limescale is less likely to adhere to the glass portion. Even when dirt adheres to the glass portion, the dirt on the glass portion is easier to remove compared to portions formed of resin or the like. As a result, the ease of cleaning the filter can be improved.

Brief Description of the Drawings

[0007] [Figure 1] Figure 1 is a perspective view showing a filter according to one embodiment installed in a water tank. [Figure 2] Figure 2 is a perspective view showing the filter according to the same embodiment removed from the aquarium. [Figure 3] Figure 3 is a side view showing the filter according to the same embodiment installed in a water tank. [Figure 4] Figure 4 is a cross-sectional view taken along line IV-IV in Figure 3. [Figure 5] Figure 5 is a plan view showing the filter according to the same embodiment installed in a water tank. [Figure 6] Figure 6 is a cross-sectional view taken along the line VI-VI in Figure 5. [Figure 7] Figure 7 is an enlarged view of the direction VII shown in Figure 4. [Modes for carrying out the invention]

[0008] The following description of a filter according to one embodiment will be made with reference to Figures 1 to 7. Note that the dimensional ratios in the drawings do not necessarily match the actual dimensional ratios, nor do the dimensional ratios between the drawings necessarily match.

[0009] Figure 1 is a perspective view showing a filter 1 according to one embodiment attached to a water tank 100, Figure 2 is a perspective view showing the filter 1 removed from the water tank 100, and Figure 3 is a side view showing the filter 1 attached to the water tank 100. [Aquarium] First, let's describe the aquarium 100, which has a removable filter 1. As shown in Figures 1 to 3, the aquarium 100 stores water (not shown) for raising organisms. Examples of organisms include ornamental fish, tropical fish, and aquatic plants.

[0010] The aquarium 100 comprises a front wall 101, a pair of side walls 102, 102, a rear wall 103, a bottom wall 104, and a lid 105 for the aquarium. The aquarium 100 is formed in a rectangular shape, for example, in plan view. Each wall 101-104 and the lid 105 for the aquarium are made of, for example, glass or transparent resin.

[0011] An opening 100a (see Figure 2) for installing a filter 1 is provided at the top of the aquarium 100. The opening 100a is located at the rear of the aquarium 100. The aquarium lid 105 is placed, for example, only on the front wall 101 and the side walls 102, 102, and not on the rear wall 103.

[0012] It is preferable that a sealant (not shown) is applied to the entire circumference (or even just a portion) of the upper end surfaces of the walls 101 to 103 of the aquarium 100. This prevents the filter 1 from sliding on the walls 101 to 103. It also prevents damage to the filter 1 or the walls 101 to 103 due to collision with them during installation. Examples of sealants include silicone-based sealants, modified silicone-based sealants, polyurethane-based sealants, and polysulfide-based sealants.

[0013] [Filter] Figure 4 is a cross-sectional view taken along line IV-IV of Figure 3. In Figure 4, the tank lid 105 from Figure 3 is omitted. As shown in Figures 3 and 4, the filter 1 comprises a front wall 11, a pair of side walls 12, 12, a rear wall 13, a bottom wall 14, and a lid 15. In this embodiment, the filter 1 is formed in a rectangular shape in plan view, but is not limited to this. For example, the filter 1 may be formed in a square shape in plan view. The shape of the filter is appropriately determined by the shape of the tank 100. In this embodiment, the filter 1 (excluding the front wall 11) is made of resin, but is not limited to this.

[0014] The lid 15 is preferably detachable. Thereby, with the filter 1 attached to the aquarium 100, the filter element 200, filter medium 300, heater 400 and the like of FIG. 4 described later can be attached to and detached from the filter 1.

[0015] The filter 1 is preferably detachable from the upper part of the aquarium 100. This facilitates attachment and detachment of the filter 1, and improves the maintainability of the filter 1. In addition, compared with a filter installed on the bottom wall 104 of the aquarium 100, the filtration capacity of the filter 1 can be increased, and the filtration performance of the filter 1 can be enhanced.

[0016] The filter 1 is provided with a mounting portion 2 for attaching to and detaching from the aquarium 100. In the present embodiment, the mounting portion 2 has a shape protruding outward from the respective upper end portions of the side walls 12, 12 and the rear wall 13 of the filter 1. The mounting portion 2 is formed in a substantially U-shape in plan view. Thereby, the mounting portion 2 can be stably attached (placed) to the side walls 102, 102 and the rear wall 103 of the aquarium 100. The mounting portion 2 is not limited to the above, and for example, may be provided only on the side walls 102, 102 of the filter 1. Further, the mounting portion 2 may be, for example, a suction cup that can be adsorbed to the side wall 102 or the rear wall 103 of the aquarium 100.

[0017] When the filter 1 is attached to the aquarium 100, the front wall 11 of the filter 1 faces the front wall 101 of the aquarium 100, the side wall 12 of the filter 1 faces the side wall 102 of the aquarium 100, and the rear wall 13 of the filter 1 faces the rear wall 103 of the aquarium 100. In the present embodiment, the side wall 12 of the filter 1 is adjacent to the side wall 102 of the aquarium 100, the rear wall 13 of the filter 1 is adjacent to the rear wall 103 of the aquarium 100, and the front wall 11 of the filter 1 is separated from the front wall 101 of the aquarium 100, but the present invention is not limited to this configuration.

[0018] The width of the filter 1 (excluding the mounting portion 2) in the left-right direction is preferably substantially the same as the inner width of the aquarium 100 in the left-right direction. This gives the user the impression that the aquarium 100 and the filter 1 are integrated, and can suppress the deterioration of the aesthetic appearance of the entire aquarium 100 caused by providing the filter 1.

[0019] Figure 5 is a plan view showing a state where the filter 1 is attached to the aquarium 100. In Figure 5, the lid 15 of Figure 4 is omitted. As shown in Figure 4 and Figure 5, the filter 1 includes a filtering section 3 that filters breeding water that has flowed into the filter 1. When the filter 1 (attachment section 2) is attached to the aquarium 100, at least a part of the filtering section 3 is submerged in the breeding water (not shown) inside the aquarium 100. Thereby, the protruding height of the filter 1 from the aquarium 100 when the filter 1 is attached to the aquarium 100 can be reduced. As a result, deterioration of the aesthetic appearance of the entire aquarium 100 caused by attaching the filter 1 to the aquarium 100 can be suppressed. In addition, darkening of the interior of the aquarium 100 due to the shadow of the filter 1 can be suppressed. Furthermore, compared with a filter placed on the upper part of the aquarium 100, the filter 1 is less likely to tip over.

[0020] At least the portion of the front wall 30 of the filtering section 3 that is submerged in the breeding water is formed of glass. According to such a configuration, dirt such as limescale is less likely to adhere to the glass portion. Even when dirt adheres to the glass portion, the dirt on the glass portion is easier to remove compared to a portion formed of resin or the like. Thereby, the ease of cleaning the filter 1 can be improved. In addition, the glass portion of the front wall 30 is less likely to be scratched. In the present embodiment, the front wall 11 of the filter 1 (excluding the front wall 60 of the outlet section 6 described later) including the front wall 30 of the filtering section 3 is formed of transparent glass, but the present invention is not limited to this. For example, the front wall 11 may be formed of colored glass. In addition, the front wall 11 of the filter 1 (excluding the portion of the front wall 30 of the filtering section 3 that is submerged in the breeding water) may be formed of resin or the like.

[0021] The filtering section 3 preferably includes a first filtering portion 31 and a second filtering portion 32 for filtering breeding water. The first filtering portion 31 is provided adjacent to the second filtering portion 32. In the present embodiment, the first filtering portion 31 is provided adjacent to the second filtering portion 32 in the left-right direction, but may be provided adjacent thereto in the up-down direction. The filtering section 3 may include only either one of the first filtering portion 31 and the second filtering portion 32.

[0022] The first filtration section 31 is equipped with a filter mounting section 311 (see Figure 5) from which the filter 200 can be attached and detached. In this embodiment, the filter mounting section 311 is a rib provided within the first filtration section 31. The filter 200 is, for example, a plate-shaped filter with a filter material such as activated carbon inside. Such a filter 200 is formed of a resin frame and a wool mat covering the filter material. The first filtration section 31 may also be capable of accommodating a filter material 300, which will be described later.

[0023] Preferably, the filter mounting section 311 is installed so that the filter 200 is inclined in a direction perpendicular to the direction of water supply (left-right direction) (front-back direction). This allows the force of the supplied water to dissipate more effectively than when the filter 200 is installed perpendicular to the water supply direction. As a result, when the supplied water comes into contact with the filter 200, it is possible to prevent the water from overflowing from the top of the first filtration section 31 without passing through the filter 200.

[0024] A partition wall 33 is provided between the first filtration section 31 and the second filtration section 32. The partition wall 33 is provided along the vertical direction. Figure 6 is a cross-sectional view taken along line VI-VI in Figure 5. As shown in Figure 6, the partition wall 33 has a first through-hole 331 and a plurality of second through-holes 332 for allowing filtered water filtered in the first filtration section 31 to flow into the second filtration section 32.

[0025] The first through-hole 331 is located at the bottom of the partition wall 33 and is connected to the flow diversion section 321 (see Figures 4 and 5), which will be described later. The first through-hole 331 is larger than the second through-hole 332. Multiple second through-holes 332 are located above the first through-hole 331 and are arranged along the left-right direction.

[0026] As shown in Figures 4 and 5, a filter medium 300 is installed in the second filtration section 32. Examples of filter medium 300 include wool, sponge, ceramic, activated carbon, zeolite, gravel, and coral.

[0027] The second filtration unit 32 preferably includes a diversion unit 321 for diverting the filtered water (or breeding water if there is no first filtration unit 31). The filter media 300 is preferably installed in contact with the diversion unit 321. This allows the filtered water to be diverted. As a result, compared to the case where the filtered water is not diverted, the diverted water passes over a wider area of ​​the filter media 300, thereby increasing the filtration efficiency of the filter media 300.

[0028] The diversion section 321 is connected to the first through-hole 331 (see Figure 6) of the partition wall 33 and is formed in a tunnel shape extending along the left-right direction. The diversion section 321 is located below the second filtration section 32. Multiple diversion holes 321a for diverting filtered water are provided at the top of the diversion section 321. It is preferable that the filter media 300 is installed above the diversion section 321. This allows filtered water (or rearing water) to enter the filter media 300 from below, making it less likely for debris to accumulate in the filter media 300 and less likely for the filter media 300 to become clogged. The diversion section 321 is not limited to the above.

[0029] The filtration unit 3 preferably includes a heater mounting section 34 into which a heater 400 for warming the aquarium water in the tank 100 can be installed. With this configuration, the heater 400 can be installed inside the filter 1. This prevents organisms from being burned by the heater 400. The heater mounting section 34 can also accommodate filter media and functions as a third filtration unit. The front wall 340 of the heater mounting section 34 is preferably made of glass. This improves the heat resistance of the heater mounting section 34.

[0030] The heater installation section 34 is provided adjacent to the second filtration section 32. In this embodiment, the heater installation section 34 is provided adjacent to the second filtration section 32 in the left-right direction, but it may also be provided adjacent to it in the up-down direction. It is preferable that the first filtration section 31, the second filtration section 32, and the heater installation section 34 are provided in a straight line along the left-right direction. The first filtration section 31, the second filtration section 32, and the heater installation section 34 are arranged in that order from the inlet section 4 side, as described later, but this is not limited to this arrangement. For example, the heater installation section 34 may be provided closer to the inlet section 4 than the first filtration section 31 and / or the second filtration section 32.

[0031] A partition wall 35 is provided between the heater installation section 34 and the second filtration section 32. The partition wall 35 is provided along the vertical direction. The partition wall 35 has a first through-hole (not shown) and a plurality of second through-holes for allowing filtered water filtered by the second filtration section 32 to flow into the heater installation section 34. The shape of the partition wall 35 is substantially the same as that of the partition wall 33. Specifically, the first and second through-holes of the partition wall 35 are substantially the same in shape and position as the first through-hole 331 and second through-hole 332 of the partition wall 33, respectively.

[0032] The heater installation section 34 preferably includes a diversion section 341 for diverting filtered water. The shape of the diversion section 341 is substantially the same as that of the diversion section 321. The diversion section 341 is connected to the first through-hole of the partition wall 35. Multiple diversion holes 341a for diverting filtered water are provided at the top of the diversion section 341. This makes it possible to increase the filtration efficiency of the filter media when a filter media is installed in the heater installation section 34.

[0033] The heater mounting section 34 is provided with a wiring pass-through hole 342 for passing the wiring of the heater 400. The wiring pass-through hole 342 is provided in the upper part of the heater mounting section 34. The wiring pass-through hole 342 is, for example, a notch provided at the upper end of the mounting section 2.

[0034] The filtration unit 3 preferably includes a storage unit 36 ​​for temporarily storing filtered water or aquarium water. The heater installation unit 34 is preferably located within the storage unit 36. With this configuration, even if the water level of the aquarium water in the tank 100 drops, the storage unit 36 ​​can maintain a state where filtered water or aquarium water is accumulated. This prevents the heater 400 from running dry due to a drop in the aquarium water level.

[0035] The storage section 36 comprises a first storage wall 361 and a second storage wall 362 arranged vertically. The first storage wall 361 and the second storage wall 362 are spaced apart from each other. The space between the first storage wall 361 and the second storage wall 362 constitutes the storage section 36. The heights of the storage walls 361 and 362 are smaller than the heights of the partition walls 33 and 35. The heights of the storage walls 361 and 362 are, for example, 30% to 70% of the height of the filter 1. The heights of the storage walls 361 and 362 are appropriately set depending on the size of the heater 400 to be installed. In this embodiment, the height of the first storage wall 361 is substantially the same as the height of the second storage wall 362, but is not limited to this.

[0036] In this embodiment, the first storage wall 361 is provided between the diversion section 321 and the partition wall 35 (within the second filtration section 32), and the second storage wall 362 is provided between the diversion section 341 and the outlet section 6, which will be described later, but the embodiment is not limited to this. For example, the first storage wall 361 may be provided between the filter mounting section 311 and the pump 5, which will be described later (within the first filtration section 31), and the second storage wall 362 may be provided within the second filtration section 32.

[0037] The filter 1 comprises an inlet 4 into which the aquarium water from the tank 100 flows, a pump 5 for introducing the aquarium water into the filter 1, and an outlet 6 for discharging the filtered water filtered by the filtration section 3. The inlet 4 is located on one side wall 12 side of the filtration section 3, and the outlet 6 is located on the other side wall 12 side of the filtration section 3. Preferably, the inlet 4, the filtration section 3, and the outlet 6 are arranged in a substantially straight line along the left-right direction.

[0038] It is preferable that the inlet 4 is provided on the bottom wall 14 of the filter 1. With this configuration, the depth to which the filter 1 is submerged in the aquarium water can be reduced. This reduces the amount of dirt that accumulates on the filter 1, improving the ease of cleaning the filter 1. In addition, since aquarium water can flow into the filter 1 even when the aquarium water level is low, the range of adjustment for the aquarium water level can be widened. Furthermore, compared to when the inlet 4 is provided on the front wall 11 of the filter 1, it is less likely to become clogged with debris, and the deterioration of the overall appearance of the aquarium 100 caused by the provision of the inlet 4 can be suppressed.

[0039] Figure 7 is an enlarged view of the view from arrow VII in Figure 4. As shown in Figure 7, it is preferable that the inlet section 4 includes a plurality of inlet holes 41 into which breeding water flows, and a filter mounting section 42 to which a filter 500 can be attached and detached. The filter mounting section 42 is located below the inlet holes 41. The filter mounting section 42 is a projection that protrudes toward the inlet section 4, and the filter 500 can be attached and detached between the inlet holes 41 and the filter mounting section 42. Examples of the filter 500 include wool and sponge.

[0040] As shown in Figures 4 and 5, in this embodiment, the pump 5 is located above the inlet 4 (inlet hole 41). A partition wall 51 is provided between the pump 5 and the filtration section 3 (first filtration section 31). The discharge section 52 of the pump 5 is connected to a through-hole (not shown) in the partition wall 51. Note that the pump 5 is not limited to the above and may be located in the filtration section 3 or the outlet section 6, for example.

[0041] The outlet section 6 is preferably provided on the front wall 11 or side wall 12 of the filter 1. With this configuration, the drop height of the filtered water discharged from the outlet section 6 can be adjusted by adjusting the water level of the rearing water in the aquarium 100. This makes it possible to adjust the amount of oxygen supplied to the rearing water (filtered water) and the amount of carbon dioxide contained in the rearing water (filtered water) that escapes. In this embodiment, the outlet section 6 is provided on the front wall 11 of the filter 1, but is not limited to this. For example, the outlet section 6 may be provided on the bottom wall 14 of the filter 1. The outlet section 6 is provided on a different wall from the inlet section 4, but may also be provided on the same wall.

[0042] The opening 61 of the outlet section 6 (see Figure 4) is preferably formed in an elongated shape. This allows the width of the outlet section 6 to be reduced while ensuring the area of ​​the opening 61. As a result, the filter 1 can be made more compact while suppressing the forceful discharge of filtered water from the opening 61. In this embodiment, the front wall 60 of the outlet section 6 is made of resin, but is not limited to this. For example, the front wall 60 of the outlet section 6 may be made of glass.

[0043] The outlet section 6 and the filtration section 3 (heater installation section 34) are separated by a second storage wall 362, but are not limited to this. The upper end position of the opening 61 is substantially the same as the upper end position of the second storage wall 362. Preferably, at least a portion of the opening 61 is immersed in the breeding water in the aquarium 100.

[0044] It is preferable that pipes are not provided at the inlet 4 and outlet 6. With such a configuration, accidents in which organisms get caught in pipes can be prevented. In addition, the deterioration of the overall aesthetic appearance of the aquarium 100 caused by providing pipes at the inlet 4 and outlet 6 can be suppressed.

[0045] The filter 1 preferably has a wiring insertion section 7 that penetrates the filter 1 (excluding the lid 15) in the vertical direction. This allows wiring for equipment such as heaters and aeration devices to be passed through the wiring insertion section 7 when they are installed outside the filter 1 (inside the aquarium 100). It is also possible to put food or other items through the wiring insertion section 7. The wiring insertion section 7 is provided adjacent to the inlet section 4.

[0046] The wiring insertion section 7 is provided with a wiring pass-through hole 71 for bringing the wiring passed through the wiring insertion section 7 out to the outside of the filter 1. The wiring pass-through hole 71 is provided at the top of the wiring insertion section 7. The wiring pass-through hole 71 is, like the wiring pass-through hole 342, a notch provided, for example, at the upper end of the mounting section 2.

[0047] The front wall 30 of the filtration section 3, the front wall 40 of the inlet section 4, the front wall 60 of the outlet section 6, and the front wall 70 of the wiring insertion section 7 are all located on the same plane. That is, the front wall 11 of the filter 1 is formed in a flat plate shape. The same applies to the rear walls and bottom walls (rear wall 13 and bottom wall 14) of each section 3, 4, 6, and 7. However, the front wall 11, rear wall 13, and bottom wall 14 of the filter 1 are not limited to the above and may be formed in a curved plate shape.

[0048] [1] As described above, the filter 1 according to this embodiment is a filter 1 that can be attached to and removed from the aquarium 100, and includes a filtration section 3 that, when attached to the aquarium 100, is submerged in the breeding water in the aquarium 100, and at least the portion of the front wall 30 of the filtration section 3 that is submerged in the breeding water is made of glass.

[0049] With this configuration, by forming the portion of the front wall 30 of the filtration unit 3 that is submerged in the aquarium water with glass, dirt such as limescale is less likely to adhere to the glass portion. Even if dirt does adhere to the glass portion, it is easier to remove the dirt from the glass portion compared to the portion made of resin or other materials. This improves the cleanability of the filter 1.

[0050] [2] Furthermore, in the filter 1 according to [1] above, it is preferable that the filter section 3 includes a heater installation section 34 on which a heater 400 can be installed, and the front wall 340 of the heater installation section 34 is made of glass.

[0051] With this configuration, the heater 400 can be installed inside the filter 1. This prevents organisms from being burned by the heater 400. In addition, by forming the front wall 340 of the heater installation section 34 with glass, the heat resistance of the heater installation section 34 can be improved.

[0052] [3] Furthermore, in the filter 1 according to [2] above, it is preferable that the filtration section 3 is equipped with a storage section 36 capable of storing filtered water or rearing water, and the heater installation section 34 is provided within the storage section 36.

[0053] With this configuration, even if the water level of the aquarium water in the tank 100 drops, the storage section 36 can maintain a state where filtered water or aquarium water is accumulated. This prevents the heater 400 from running dry due to a drop in the aquarium water level.

[0054] [4] Furthermore, it is preferable that the filter 1 relating to any one of the above [1] to [3] is equipped with an inlet 4 into which the breeding water in the aquarium 100 flows, and the inlet 4 is provided on the bottom wall 14 of the filter 1.

[0055] With this configuration, the depth to which the filter 1 is submerged in the aquarium water can be reduced. This reduces the amount of dirt that accumulates on the filter 1, improving its ease of cleaning. Furthermore, since aquarium water can flow into the filter 1 even when the water level is low, the range of adjustment for the water level can be widened.

[0056] [5] Furthermore, it is preferable that the filter 1 relating to any one of the above [1] to [4] is equipped with an outlet 6 for discharging the filtered water filtered by the filtration section 3, and the outlet 6 is provided on the front wall 11 or side wall 12 of the filter 1.

[0057] With this configuration, the drop height of the filtered water discharged from the outlet 6 can be adjusted by adjusting the water level of the aquarium water in the tank 100. This makes it possible to adjust the amount of oxygen supplied to the aquarium water (filtered water) and the amount of carbon dioxide contained in the aquarium water (filtered water) that escapes.

[0058] [6] Furthermore, in a filter 1 relating to any one of the above [1] to [5], it is preferable that there are no pipes at the inlet 4 and outlet 6.

[0059] This configuration prevents accidents where organisms get caught in the pipes. Furthermore, it minimizes the deterioration of the overall aesthetics of the aquarium 100 caused by the installation of pipes at the inlet 4 and outlet 6.

[0060] It should be noted that the filter 1 is not limited to the configuration of the embodiment described above, nor is it limited to the effects and benefits described above. Furthermore, it goes without saying that the filter 1 can be modified in various ways without departing from the spirit of the present invention. For example, one or more of the configurations and methods described below may be arbitrarily selected and adopted in the configurations and methods of the embodiment described above.

[0061] In the above embodiment, the inlet portion 4 is provided on the side wall 12 side of the filter 1, but the configuration is not limited to this. For example, the inlet portion 4 may be provided in the center in the width direction of the filter 1. In such a configuration, two or more outlet portions 6 may be provided.
