Description

  This invention relates to an aquarium that can make appreciating fish such as goldfish and tropical fish more interesting.

  There is known a water tank in which a downward auxiliary water tank is installed in the main water tank (Patent Document 1). This water tank is based on the idea of the applicant.

  The downward auxiliary water tank is, for example, a transparent body having a dome-shaped top, and holds the entire periphery of the lower end edge below the water surface in the main water tank, and exhausts the internal air to fill the water, By keeping the water level higher than that of the main water tank, the swimming range of the fish in the main water tank can be expanded to the auxiliary water tank, and the fish swimming in the auxiliary water tank can be viewed from the side. In addition, when a water pump is installed in the main water tank and the water from the water pump is allowed to flow from the top of the auxiliary water tank to the outer surface, the appearance of the auxiliary water tank can be further improved.

Japanese Patent No. 2709196

  When such conventional technology is used, the water flowing down the outer surface of the auxiliary water tank has not undergone any special purification treatment, so the transparency of the outer surface of the auxiliary water tank is lost in a short period of time, and the aesthetics may be impaired. There was no problem.

  Therefore, in view of the problems of the prior art, the object of the present invention is to continuously filter the water flowing down the outer surface of the auxiliary water tank by providing an internal filtration type or external filtration type filter on the suction side of the water pump. Another object of the present invention is to provide a water tank that can keep the outer surface of the auxiliary water tank small.

  In order to achieve such an object, the structure of the present invention includes a main water tank, an auxiliary water tank installed in a downward direction in the main water tank and having a discharge nozzle penetrating inside and outside, and a water in the main water tank. The auxiliary water tank holds the entire circumference of the lower edge under the water surface in the main water tank, and the water pump has a filter for filtration on the suction side. The gist of the invention is that the discharge side is detachably connected to the discharge nozzle through a transparent pipe in the auxiliary water tank.

  The auxiliary water tank can be installed in the main water tank via a plurality of spacers, an upward concave portion can be formed at the top of the auxiliary water tank, and the discharge nozzle can be opened at the bottom surface of the concave portion.

  In addition, the water from the discharge nozzle can spread over the entire outer surface of the auxiliary water tank and flow down, and the filter is installed at the bottom of the main water tank, and in addition to the water pump, it is a light that illuminates the inside of the auxiliary water tank One or both of the appliances and heaters that heat the water in the main water tank can be incorporated.

  Further, a switching valve may be mounted on the discharge side of the water pump, and a transparent protrusion that enters the auxiliary water tank may be formed at the bottom of the main water tank. You may combine materials.

  When this configuration is used, the auxiliary water tank can make the fish in the main water tank swim high by filling the inside with water. On the other hand, the water pump sucks the water in the main water tank and causes the water to flow down to the outer surface of the auxiliary water tank via the discharge nozzle at the top of the auxiliary water tank, but the filter for filtration on the suction side of the water pump is the auxiliary water tank. The water flowing down the outer surface of the water can be purified, and the transparency of the auxiliary water tank can be maintained for a long time. The auxiliary water tank is used by inverting a transparent water tank made of glass or a plastic material. The shape of the auxiliary water tank is preferably, for example, a cylindrical shape whose top is closed like a dome, but other shapes may be used.

  The auxiliary water tank has a large size, for example, an outer diameter of at least 10 cm or more, preferably 30 cm or more, and a gorgeous atmosphere can be created by protruding upward from the water surface of the main water tank by 10 cm or more, particularly preferably 40 cm or more. Moreover, it is preferable to set the discharge amount of a water pump so that the water which flows out from the discharge nozzle of the top part of an auxiliary water tank may spread and flow over the whole outer surface of an auxiliary water tank. By bringing water into contact with the air using the entire outer surface of the auxiliary water tank, the dissolved oxygen in the water can be increased and the activity of the fish can be maintained well. Note that the transparent pipe in the auxiliary water tank does not appear extremely conspicuous from the outer surface of the auxiliary water tank.

  The filter for filtration may be operated as an internal filtration type by being installed in the water inside the main water tank, or may be operated as an external filtration type by being installed outside the main water tank. For the filter, for example, a filter medium such as porous ceramics or activated carbon may be used alone or in combination, in addition to a fibrous filter medium such as plastic fiber, carbon fiber, glass wool fiber, or the like. A biofilter based on aerobic or anaerobic microorganisms may be used in combination.

  In the upward concave portion formed at the top of the auxiliary water tank, water from the discharge nozzle that opens to the bottom surface accumulates, overflows from the entire periphery, and flows down the outer surface of the auxiliary water tank. Therefore, for example, floating aquatic plants or igniting a candle to float on the water surface in the recess can produce a special interest.

  The filter installed at the bottom of the main water tank can be combined in a compact manner by incorporating a water pump. Further, if one or both of the lighting device and the heater are incorporated in the filter, the swimming environment of the fish is not narrowed by the lighting device or the heater, and there is no possibility of damaging the fish body due to contact with these fish.

  During normal operation, the switching valve on the discharge side of the water pump allows water to flow out of the discharge nozzle by communicating the discharge side of the water pump with the discharge nozzle at the top of the auxiliary water tank. In such cases, the discharge side of the water pump can be switched to the drain hose side communicating with the outside, and the water in the tank can be discharged to the outside using the water pump. At this time, it is preferable that the auxiliary water tank gradually lowers the inner water surface by injecting air little by little from the outside through an air hose. However, the drainage hose may be attached to and detached from the switching valve as necessary, or may be always connected to the switching valve.

  Hereinafter, embodiments of the invention will be described with reference to the drawings.

  The water tank mainly comprises a main water tank 11, an auxiliary water tank 12, a water pump 13, and a filter 14 (FIG. 1).

  The main water tank 11 is, for example, a circular bowl-shaped bottomed container and can be filled with water. The main water tank 11 may be transparent or opaque. A filter 14 is installed at the bottom of the main water tank 11 through a mesh plate 15 on the upper surface.

  The auxiliary water tank 12 is, for example, an inverted cylindrical container whose top is closed in a dome shape. The auxiliary water tank 12 is transparent, and is installed in the main water tank 11 via a plurality of spacers 12 a, 12 a... So that the entire periphery of the lower end edge is below the water surface in the main water tank 11. However, each spacer 12a is erected with the lower end portion detachably stored in the pocket 15a of the mesh plate 15.

  The water pump 13 is integrated into the filter 14 so as to be housed in a case 15b having an open bottom attached to the lower surface of the mesh plate 15. The suction side of the water pump 13 opens downward in the case 15 b, and the discharge side penetrates the mesh plate 15 from the bottom to the top and is connected to the switching valve 13 a at the 3 port 2 position on the mesh plate 15. ing.

  One outlet side of the switching valve 13a is connected to the discharge nozzle 16 at the top of the auxiliary water tank 12 through a transparent pipe 13b. The discharge nozzle 16 penetrates the top of the auxiliary water tank 12 in and out. The lower end of the transparent pipe 13b is detachably connected to one outlet side of the switching valve 13a via a bellows type connector 13c (FIGS. 2A and 2B). However, FIGS. 2A and 2B are schematic views when the connector 13c is expanded and contracted, and the transparent pipe 13b is attached to and detached from the outlet side of the switching valve 13a. The connector 13c only needs to be able to detachably connect the transparent pipe 13b and the switching valve 13a, and may not be a bellows type.

  The filter 14 is disposed below the mesh plate 15 (FIG. 1). The filter 14 can continuously filter the water in the main water tank 11 sucked by the water pump 13 through the mesh plate 15. A guide (not shown) is formed in the filter 14 so that water passing through the mesh plate 15 is appropriately filtered and reaches the suction side of the water pump 13 in the case 15b. However, the mesh plate 15 may allow water to pass through only a part of the upper surface of the filter 14 instead of the entire upper surface.

  The filter 14 includes a heater 17 and a lighting fixture 18. The heater 17 is accommodated in a pocket 15c attached to the mesh plate 15 (FIG. 3A) and is not exposed on the mesh plate 15. The heater 17 heats the water in the main water tank 11 sucked by the water pump 13. Moreover, the lighting fixture 18 is accommodated upward in the pocket 15d attached to the mesh board 15 (FIG. 3 (B)), and the light projection part is exposed on the mesh board 15. FIG. The luminaire 18 lights up the auxiliary water tank 12 on the mesh plate 15. In addition, what is necessary is just to provide the heater 17 and the lighting fixture 18, respectively, respectively, if needed, The one or both may be provided and both may be abbreviate | omitted.

  Such a water tank fills the main water tank 11 with water so that the water surface in the main water tank 11 is above the lower edge of the auxiliary water tank 12 (FIG. 1). Subsequently, when the air hose 21 is inserted into the auxiliary water tank 12 high, an air pump (not shown) is connected to one end of the air hose 21 and the air in the auxiliary water tank 12 is discharged, the water in the main water tank 11 becomes high in the auxiliary water tank 12. Since the water is sucked up, the whole of the auxiliary water tank 12 is filled with water and the air hose 21 is removed. When water is sucked into the auxiliary water tank 12, the water surface in the main water tank 11 is lowered, so that the lower end edge of the auxiliary water tank 12 does not become higher than the water surface in the main water tank 11. Replenish. Therefore, if the fish is discharged into the main water tank 11, the fish can swim high not only in the main water tank 11 but also in the auxiliary water tank 12.

  Subsequently, when the water pump 13 is operated, the water in the main water tank 11 is sucked through the filter 14 and flows upward from the discharge nozzle 16 at the top of the auxiliary water tank 12 through the switching valve 13a and the transparent pipe 13b. In addition, the water from the discharge nozzle 16 flows down to the main water tank 11 while forming a water film over the entire outer surface of the auxiliary water tank 12, and in combination with the fish in the auxiliary water tank 12, A unique interest can be realized. The filter 14 purifies the water sucked by the water pump 13 and prevents the outer surface of the auxiliary water tank 12 from being contaminated within a short period.

  When the water in the main water tank 11 and the auxiliary water tank 12 is changed and the inside is cleaned, one end of the drain hose 22 communicating with the outside is connected to the switching valve 13a, and the switching valve 13a is drained from the transparent pipe 13b side. Switch to the 22 side. If the water pump 13 is operated as it is, the water in the main water tank 11 can be drained to the outside via the drain hose 22, and then the air hose 21 is inserted into the auxiliary water tank 12, and the auxiliary is provided via the air hose 21. By injecting air into the water tank 12 little by little, the water in the auxiliary water tank 12 is discharged into the main water tank 11. When the water in the main water tank 11 and the auxiliary water tank 12 is sufficiently discharged, the connector 13c can be removed from the switching valve 13a, and the auxiliary water tank 12 can be separated from the main water tank 11 to clean the inside.

Other embodiments
