Description

[Technical field]

[0001] The present invention relates to an ornamental aquarium that utilizes the water surface to display ornamental objects. [Background technology]

[0002] Various types of aquariums for fresh flowers have been developed (see, for example, Patent Document 1 and Patent Document 2). Patent Document 1 discloses a flower showcase for displaying cut flowers, which is provided with a plurality of tiers in a stepped manner. Patent Document 2 discloses a cut flower sales case, which is a thin sales case that is easily reachable by people. These technologies are understood to be aimed at florists. Therefore, the structure of the device is considered to be large-scale. Also, the use of the device is limited to commercial use. On the other hand, seasonal flowers are displayed floating on the water's edge in the water basins at the temizuya (purification fountains) of temples and shrines, and are known to attract tourists as flower temizu (purification fountains).

[0003] [Patent Document 1] JP 2013-90671 A [Patent Document 2] JP 2003-325285 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, flower water basins at temples and shrines and other establishments have issues such as the fact that they cannot be placed anywhere because they use a fixed, immovable object - a large water basin in the chozuya - and the lack of freedom in designing the arrangement of the flowers, as well as the inability to apply the characteristics of conventional aquariums. The present invention has been made in consideration of the above circumstances, and aims to provide an ornamental aquarium that can be moved freely anywhere and that can easily maintain the freshness of ornamental plants to be exhibited. [Means for solving the problem]

[0005] The ornamental aquarium of the present invention is an ornamental aquarium for placing ornamental objects on the water surface, and is characterized in that it comprises an aquarium body having a flat, shallow outer shape with a bottom plate and side plates located around the bottom plate and housing the lower part of the ornamental object underwater, a cooling water outlet port that discharges cooling water supplied through the bottom plate into the inside of the aquarium body, and a circulating water recovery port that circulates the cooling water inside the aquarium body, recovers it as circulating water, and leads it out through the bottom plate. Therefore, the ornamental aquarium of the present invention can be displayed anywhere with a shallow water depth limited by the height of the side panel that holds the lower part of the ornamental object underwater, and the supply of cooling water has the effect of maintaining the freshness of the ornamental object and ensuring a beautiful appearance. In addition, since the water depth is shallow, the gushing state caused by the discharge of cooling water from the cooling water discharge port is easily visible, which tends to create a further beautiful appearance. The amount of water in the aquarium is reduced, making it easy to effectively use the cooling water.

[0006] In addition, an ornamental aquarium according to one embodiment of the present invention is characterized in that it is provided with a cylindrical spring water level wall located outside the cooling water outlet in the form of a vertical wall from the bottom plate to store the cooling water discharged from the cooling water outlet, maintain the water level of the cooling water, and allow it to flow out in a spring-like manner from the upper end. In addition, in an ornamental aquarium according to one embodiment of the present invention, the height of the spring water level wall is either higher than the side panel, lower than the side panel, or the same height as the side panel. In addition, in an ornamental aquarium according to one embodiment of the present invention, the spring water level wall is cylindrical. In addition, an ornamental aquarium according to one embodiment of the present invention is characterized in that it is provided with a cylindrical auxiliary wall having an outer diameter smaller than that of the inner wall of the spring water level wall, which is disposed in a wall-like manner along the spring water level wall between the cooling water outlet and the spring water level wall. In addition, an ornamental aquarium in one embodiment of the present invention is characterized in that it comprises a top plate supporting the bottom plate and a support portion supporting the top plate from below, and is located between the cooling water outlet and the circulating water recovery outlet in the vertical space formed below the top plate by the support portion, and is further characterized by comprising a circulating device for steadily circulating the circulating water, and a cooling device for cooling the circulating water to produce the cooling water. In addition, an ornamental aquarium in one embodiment of the present invention is characterized in that it is provided with an aquarium stand cover that blocks visibility from the outside between the floor surface on which the base plate supporting the support portion is placed and a height that exposes the upper ends of the side panels. Effect of the Invention

[0007] The ornamental aquarium according to the present invention can be used anywhere to display ornamental objects in a shallow water environment, and has the effect of easily maintaining the freshness of the ornamental objects and ensuring a beautiful appearance. In addition, since the water depth of the aquarium body is shallow, the gushing state caused by the discharge of cooling water from the cooling water discharge port is easily visible, which makes it easier to create a beautiful appearance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 6). [Embodiment 1] Figure 1 An ornamental aquarium 1a according to a first embodiment of the present invention will be described with reference to Fig. 1. When there is no need to distinguish it from other embodiments, it may simply be referred to as ornamental aquarium 1. FIG. 1 is a schematic diagram showing an overall outline of an ornamental aquarium 1a according to a first embodiment of the present invention as seen through from the side. In ornamental aquarium 1a, ornamental objects (not shown for ease of viewing) are placed on water surface WL. Ornamental aquarium 1a also includes a tank body 10 having a flat, shallow outer shape with a bottom plate 12 and side plates 14 positioned around bottom plate 12 to accommodate the lower part of the ornamental object underwater, a cooling water outlet 16 that discharges cooling water WR supplied through bottom plate 12 into tank body 10, and a circulating water recovery port 18 that recovers circulating water WJ obtained by circulating cooling water WR inside tank body 10 and leads it out through bottom plate 12.

[0010] The ornamental aquarium 1a includes a flat, shallow aquarium body 10 equipped with side panels 14 for housing the lower part of an ornamental object underwater, which makes it easy to realize a shallow water depth and to increase the usability of the water surface WL. The cooling water outlet 16 that supplies the cooling water WR and the circulating water recovery port 18 that recovers the circulating water WJ that has circulated within the aquarium body 10 circulate as the circulating water WJ through the common bottom plate 12, making it easy to supply the cooling water WR efficiently. The cooling water outlet 16 is easily disposed, for example, near the center of the bottom plate 12. The location may be changed as appropriate depending on the design of the ornamental objects in the aquarium body 10. In addition, the height of the side plate 14 is adapted to the lower part of the ornamental object, and the lower part of the ornamental object is adjusted to a size adapted to the side plate 14, so that the circulation of the cooling water WR under the shallow water depth due to the flat and shallow outer shape with a limited height in advance facilitates diffusion throughout the entire aquarium body 10, which makes it easy to improve the supply efficiency of the cooling water WR. In addition, because the water depth is shallow, it is easy to express a gushing state accompanied by the discharge of the cooling water WR from the cooling water discharge port 16, which tends to produce a more beautiful appearance. The gushing state can be easily realized in different states by changing the opening area of ​​the cooling water discharge port 16 or the flow speed of the cooling water WR.

[0011] Since the cooling water WR is supplied as the circulating water WJ, it is easy to cool the ornamental objects. In other words, it is easy to cool the ornamental objects according to their condition and maintain their freshness, and it is easy to prevent deterioration and contamination of the ornamental objects and ensure their lifespan. The ornamental aquarium 1a according to this embodiment can be displayed anywhere with a shallow water depth limited by the height of the side panel 14 that holds the lower part of the ornamental object underwater, and the supply of cooling water WR has the effect of maintaining the freshness of the ornamental object and ensuring a beautiful appearance. In addition, because the water depth is shallow, the gushing state caused by the discharge of cooling water WR from the cooling water discharge port 16 is easily visible, which tends to create a more beautiful appearance. The amount of water in the aquarium can be reduced, making it easy to make the cooling water act effectively.

[0012] Ornamental objects include flowers that are floated on the water surface WL (for example, cut flowers with short stems that are floated on the water). For flowers of a size that are generally used for display and appreciation, it is easy to ensure sufficient water supply through the short stems when the flowers are floated on the water as cut flowers with short stems. Therefore, by applying an aquarium with a depth that matches the characteristics of such ornamental objects in the depth direction, an aquarium that provides sufficient displayability for the purpose of, for example, displaying and appreciating flowers in a planar manner can be ensured. Since the water tank body 10 is flat and shallow, and a shallow water depth can be easily achieved, it is easy to effectively supply cooled circulating water WJ to the water surface WL or water close to the water surface WL. In addition, since the water depth is shallow, a fountain state is easily generated around the cooling water outlet 16 when the cooling water is discharged, and it is easy to ensure a beautiful fountain. The depth of the aquarium body 10 (height of the side panels 14) is preferably about 10 cm, for example, taking into consideration the vertical dimension of the ornamental object to be floated on the water surface WL. By setting the depth at this level, it is easy to secure a constant amount of water, and it is easy to make an aquarium with good controllability over water quality and high stability. The flat and shallow shape of the aquarium body 10 can be obtained by setting the horizontal dimension (diameter) of the circular shape in plan view to, for example, 50 cm when the depth dimension of the side panels 14 is 10 cm. In this case, the length (vertical) / width (horizontal) ratio is 10 / 50=0.2, and 0.2 is obtained. Visually, flatness is easily recognized if the aspect ratio is about 0.3 or less. With this aspect ratio, it is easy to configure a water environment with a shallow water depth that includes the water surface WL, making it easy to set up the water environment as needed. In addition, a shallow water depth makes it easy to reduce the amount of water used by the aquarium body 10, and the load on the cooling device 34 and the circulation device 36. In this case, the thickness of the side panels 14 is 1 cm (10 mm). When the bottom panel 12 has a diameter of 50 cm and the side panels 14 are 10 cm high, a thickness of about 1 cm (10 mm) is sufficient strength. For example, when the diameter of the aquarium body 10, which is circular in plan view, is greater than 50 cm, the side panels 14 need to be even thicker. An appropriate thickness is selected depending on the size in plan view. The planar size of the aquarium body 10 can be, for example, a circle with a diameter of 50 cm, which can easily secure a certain display area for an ornamental object that can be viewed, and therefore visibility and aesthetic appeal can be easily ensured. The cooling water outlet 16 and the circulating water recovery port 18 have simple shapes, and the area of ​​the aquarium body 10 can be easily enlarged or reduced as needed.

[0013] In the aquarium body 10 of the ornamental aquarium 1a (ornamental aquarium 1), the bottom plate 12 and side plates 14 are made of, in addition to transparent acrylic resin, for example, polyvinyl chloride resin, metal, etc. The bottom plate 12 is easily supported reliably by the top plate 30, which makes it easy to stabilize the support of the aquarium body 10. The top plate 30 is also easily supported reliably by the support parts 32 made of aluminum. This makes it easy to hold the aquarium body 10 with high stability overall. A base bottom plate 38 that supports the support portion 32 is disposed on a floor surface 42 on which the ornamental aquarium 1a is placed. The top plate 30 and the base bottom plate 38 are made of, for example, vinyl chloride resin. The frame-like support portion 32 is an aluminum frame, which can easily reduce the weight, and therefore the ornamental aquarium tank 1a can be easily installed and moved. It is preferable to place a filter portion (eg, sponge, mesh) at the inlet of the circulating water WJ of the circulating water recovery port 18 (the filter portion is not shown in Figs. 1, 2 and subsequent Figs. for ease of understanding). The ornamental aquarium 1a (aquarium body 10) has a planar shape such as a circle, an ellipse, or a rectangle when viewed from above, that is, the shape of the bottom plate 12. The ornamental aquarium 1 can be easily sized appropriately according to the size of the installation location.

[0014] The ornamental aquarium 1a comprises a top plate 30 supporting a bottom plate 12, and a support portion 32 supporting the top plate 30 from below. In the vertical space formed by the support portion 32 below the top plate 30, the ornamental aquarium 1a is provided with a cooling device 34 located between the cooling water outlet 16 and the circulating water recovery port 18, which cools the circulating water WJ to generate cooling water WR, and a circulation device 36 which constantly circulates the circulating water WJ. The circulation device 36 may have a filtering function for filtering and purifying the circulating water WJ. The cooling water WR is shown as cooling water WR at the outlet cooled by the cooling device 34, but it is also circulating water WJ, so that although it is shown as one of them, it also corresponds to the other. Either the cooling device 34 or the circulation device 36 may be located on the side of the circulating water recovery port 18. In the ornamental aquarium 1a, a cooling device 34 that cools the circulating water WJ to generate cooling water WR, and a circulation device 36 that circulates the circulating water WJ are located in the vertical space formed by the support part 32 below the top plate 30, making it easy to efficiently and effectively supply the cooling water WR and circulate the circulating water WJ. Ornamental aquarium 1a (ornamental aquarium 1) is provided with an aquarium stand cover 40 that blocks external visibility from the height between a floor surface 42 on which a base plate 38 supporting the support portion 32 is disposed and a height that exposes the upper ends of the side plates 14. The aquarium stand cover 40 is easily modified in various ways to allow ornamental objects on the water surface WL or in the water near the water surface WL to be sufficiently visually stimulated.

[0015] [Embodiment 2] Figs. 2 and 3 An ornamental aquarium 1b (ornamental aquarium 1) according to embodiment 2 of the present invention will be described with reference to Figures 2 and 3. The basic configuration is similar to ornamental aquarium 1a of embodiment 1, so the same elements are given the same reference numerals and descriptions are omitted where appropriate. Ornamental aquarium 1b may also be referred to simply as ornamental aquarium 1 when there is no need to distinguish it from other embodiments, as in embodiment 1. FIG. 2 is a schematic diagram showing an overall outline of an ornamental aquarium 1b according to a second embodiment of the present invention as seen through from the side. FIG. 3 is a schematic perspective view showing an outline of the appearance of the ornamental aquarium 1b shown in FIG. 2 in a drained state, as viewed obliquely from above. The ornamental aquarium 1b according to this embodiment differs from the ornamental aquarium 1a according to the first embodiment in that a spring water level wall 22 is provided on the outside of the cooling water outlet port 16.

[0016] The ornamental aquarium 1b is provided with a cylindrical spring water level wall 22 located in the aquarium body 10 outside the cooling water outlet 16 and extending in the form of a vertical wall from the bottom plate 12 to store the cooling water WR discharged from the cooling water outlet 16, maintain the water level of the cooling water WR (the water surface within the spring water level wall 22), and allow it to flow out in a spring-like manner from the upper end. The spring water level wall 22 maintains the water level of the cooling water WR (the water surface inside the spring water level wall 22) and causes the cooling water WR to flow out from the upper end in a spring-like manner, making it easy to reproduce a spring state and improve the aesthetic appearance. In addition, since the cooling water WR flows out from the upper end of the spring water level wall 22, it is easy to efficiently supply the cooling water WR to the entire water tank body 10 and easy to make the cooling water WR act effectively as circulating water WJ. The spring water level wall 22 is preferably disposed near the center of the bottom plate 12. The position is appropriately set according to the exhibition intent. The cooling water WR flowing out from the spring water level wall 22 tends to further emphasize the gushing state. The cross-sectional shape of the spring water level wall 22 in the width direction can be easily selected from various shapes such as a circle, a rectangle, and others. The aquarium stand cover 40 is similar to that of the first embodiment (FIG. 1), but is additionally shown with ventilation holes 40v (FIG. 3).

[0017] In the ornamental aquarium 1b, the height of the spring water level wall 22 is higher than the side panel 14. The height (position of the upper end) of the spring water level wall 22 can be set in various ways. In this embodiment, the height of the spring water level wall 22 is higher than the side plate 14, so the water level WL of the aquarium body 10 can be easily raised to a position closer to the upper end of the side plate 14, making it easier to make the water depth deeper than in other embodiments. Note that a height comparison line CHL is shown as a reference line at the height of the upper end of the side plate 14 to compare the height of the spring water level wall 22 with the height (upper end) of the side plate 14. 1 shows an overview of the comparison between the height of the spring water level wall 22 and the height of the side panel 14. When the spring water level wall 22 is higher than the side plate 14 (Embodiment 2: Figures 2 and 3: spring water level wall 22), the water surface WL of the aquarium body 10 can be easily raised to a position close to the height of the side plate 14, making it easier to make the water deeper. When the spring water level wall 22 is lower than the side plate 14 (Embodiment 3: FIG. 4: spring water level wall 22c), it is easy to lower the water surface WL of the aquarium body 10 to a position lower than the height of the side plate 14, and it is easy to make the water depth shallow. When the spring water level wall 22 is at the same height as the side plate 14 (Fourth embodiment: FIG. 5: spring water level wall 22d), it is easy to adjust the position of the water surface WL of the aquarium body 10 within the range of the height of the side plate 14. When there is no need to distinguish between the spring water level wall 22, the spring water level wall 22c, and the spring water level wall 22d, they will be referred to as the spring water level wall 22.

[0018] In the ornamental aquarium 1b, the spring water level wall 22 is tubular, and more specifically, cylindrical (see FIG. 3). Since the spring water level wall 22 is cylindrical, it is easy to expand the outflow of the cooling water WR evenly in all directions, so it is easy to reliably reproduce the state of a spring and to supply the cooling water WR evenly to the entire ornamental aquarium 1. This makes it easy to improve the management of the display quality of the ornamental objects. Also, since the spring water level wall 22 is higher than the side plate 14, the cooling water WR flowing out from the spring water level wall 22 is easily recognized as a more accurate state of a spring, which creates a beautiful appearance. In addition, since the spring water level wall 22 is raised above the water surface WL, it is easy to supply the cooling water WR in a spring-like manner from the upper end. When the height of the spring water level wall 22 is higher than the side plate 14, if the height is about 1 cm (10 mm) above the side plate 14, the spring-like discharge state can be clearly and accurately visually observed, which makes it easy to improve the aesthetic appearance. The other configurations are similar to those of the other embodiments, and therefore will not be described.

[0019] [Embodiment 3] Figure 4 With reference to Fig. 4, an ornamental aquarium 1c (ornamental aquarium 1) according to embodiment 3 of the present invention will be described. The basic configuration is similar to ornamental aquarium 1a of embodiment 1 and ornamental aquarium 1b of embodiment 2, so the same elements are given the same reference numerals and descriptions are omitted where appropriate. Ornamental aquarium 1c may also be referred to simply as ornamental aquarium 1 when there is no need to distinguish it from other embodiments, as with embodiment 1. FIG. 4 is a schematic diagram showing a partial configuration of an aquarium body 10, which is part of an ornamental aquarium 1c according to embodiment 3 of the present invention, as viewed perspectively from the side in the case where the height of the spring water level wall 22c relative to the side panel 14 is lowered.

[0020] The ornamental aquarium 1c includes a cylindrical spring water level wall 22c that is shorter in height than the spring water level wall 22 in the embodiment 2. The spring water level wall 22c is located outside the cooling water outlet 16 in the form of a vertical wall from the bottom plate 12, stores the cooling water WR discharged from the cooling water outlet 16, maintains the water level of the cooling water WR (the water surface inside the spring water level wall 22c), and allows it to flow out in a spring-like manner from the upper end. The spring water level wall 22c maintains the water level of the cooling water WR (the water surface inside the spring water level wall 22c) and causes the cooling water WR to flow out from the upper end in a gushing state, which makes it easy to reproduce a gushing state and improves the aesthetic appearance. In addition, since the cooling water WR flows out from the upper end of the spring water level wall 22c, the cooling water WR can be efficiently supplied to the entire water tank body 10 and the cooling water WR can be effectively used as circulating water WJ. The cooling water WR flowing out from the spring water level wall 22c further emphasizes the gushing state.

[0021] In the ornamental aquarium 1c, the height of the spring water level wall 22c is lower than the side plate 14. Since the height of the spring water level wall 22c is lower than the side plate 14, it is easy to lower the water surface WL of the aquarium body 10 to a position lower than the side plate 14, and the water depth can be made shallower than in other embodiments. In order to compare the height of the spring water level wall 22c with the height (upper end) of the side plate 14, a height comparison line CHL is shown as a reference line at the height of the spring water level wall 22c. In the ornamental aquarium 1c, the spring water level wall 22c is cylindrical. This provides the same effects as the spring water level wall 22 in the second embodiment. In addition, it is easy to accommodate the vertical size of the ornamental object. The other configurations are similar to those of the other embodiments, and therefore will not be described.

[0022] [Embodiment 4] Figure 5 With reference to Fig. 5, an ornamental aquarium 1d (ornamental aquarium 1) according to embodiment 4 of the present invention will be described. The basic configuration is similar to ornamental aquarium 1a according to embodiment 1 to ornamental aquarium 1c according to embodiment 3, so the same elements are given the same reference numerals and descriptions are omitted where appropriate. As with embodiment 1, ornamental aquarium 1d may also be referred to simply as ornamental aquarium 1 when there is no need to distinguish it from other embodiments. FIG. 5 is a schematic diagram showing a partial configuration of an aquarium body 10, which is part of an ornamental aquarium 1d according to embodiment 4 of the present invention, as viewed perspectively from the side when the height of the spring water level wall 22d relative to the side panel 14 is made equal.

[0023] The ornamental aquarium 1d is provided with a spring water level wall 22d that is lower in height than the spring water level wall 22 in the second embodiment and has the same height as the side plate 14. In other words, the ornamental aquarium 1d is provided with a cylindrical spring water level wall 22d that is positioned outside the cooling water discharge port 16 in a vertical wall shape from the bottom plate 12, stores the cooling water WR discharged from the cooling water discharge port 16, maintains the water level of the cooling water WR (the water surface within the spring water level wall 22d) and causes it to flow out in a spring-like manner from the upper end. The spring water level wall 22d maintains the water level of the cooling water WR (the water surface inside the spring water level wall 22d) and causes the cooling water WR to flow out from the upper end in a spring-like manner, making it easy to reproduce a spring state and improve the aesthetic appearance. In addition, since the cooling water WR flows out from the upper end of the spring water level wall 22d, it is easy to efficiently supply the cooling water WR to the entire water tank body 10 and easy to make the cooling water WR act effectively as circulating water WJ.

[0024] In the ornamental aquarium 1d, the height of the spring water level wall 22d is the same as that of the side plate 14. Since the height (upper end position) of the spring water level wall 22d is the same as that of the side plate 14, it is easy to adjust the water level of the aquarium body 10 within the range of the height of the side plate 14. Note that a height comparison line CHL is shown as a reference line at the height of the spring water level wall 22d to compare the height of the spring water level wall 22d with the height (upper end) of the side plate 14. In the ornamental aquarium 1d, the spring water level wall 22d is cylindrical. This provides the same effects as the spring water level wall 22 in the second embodiment. In addition, it is easy to accommodate the vertical size of the ornamental object. The other configurations are similar to those of the other embodiments, and therefore will not be described.

[0025] [Embodiment 5] Figure 6 With reference to FIG. 6, an ornamental aquarium 1e (ornamental aquarium 1) according to embodiment 5 of the present invention will be described. The basic configuration is similar to ornamental aquarium 1a according to embodiment 1 to ornamental aquarium 1d according to embodiment 4, so the same elements are given the same reference numerals and descriptions thereof will be omitted as appropriate. When ornamental aquarium 1e does not need to be distinguished from other embodiments, as in embodiment 1, it may be simply referred to as ornamental aquarium 1. Note that in embodiments 3 to 5, descriptions of parts common to embodiments 1 and 2 will be omitted as appropriate. FIG. 6 is a schematic diagram showing a partial configuration of an aquarium main body 10, which is part of an ornamental aquarium 1e according to embodiment 5 of the present invention, as viewed perspectively from the side, in the case where a cylindrical auxiliary wall 24 having an even smaller outer shape is provided inside the spring water level wall 22. The ornamental aquarium 1e is provided with a cylindrical auxiliary wall 24 having an outer shape smaller than the inner wall of the spring water level wall 22, which is a wall shape along the spring water level wall 22 between the cooling water outlet 16 and the spring water level wall 22. The height of the cylindrical auxiliary wall 24 may be lower than that of the spring water level wall 22. The cylindrical auxiliary wall 24 further restricts the flow of the cooling water WR relative to the spring water level wall 22, which makes it easier to improve the visibility of the flow in the spring state, improves awareness of the spring state, and improves the aesthetic appearance. The cylindrical auxiliary wall 24 is easy to function in the same way as the spring water level wall 22. The other configurations are similar to those of the first to fourth embodiments, so the description will be omitted. [Industrial Applicability]

[0026] The ornamental aquarium of the present invention provides a novel ornamental aquarium that can exhibit a beauty never seen before, and since it can artificially create a beautiful waterfront scene, it can be widely and effectively used in many aspects of daily life. [Explanation of symbols]
