Description

[Detailed description of the invention] This invention relates to an aquarium.

In aquariums that house tropical and subtropical fish that are sensitive to changes in water temperature, it is necessary to maintain a constant water temperature.

For this reason, a sensor element such as a thermostat is enclosed in a waterproof container, which is suspended in water from the top of the tank.
However, this aquarium has the disadvantage that the lead wire of the temperature sensor extends above the aquarium, reducing the visual and decorative effects of the aquarium. There was also the problem of detecting temperature errors due to lowering of the water level and exposing a portion of the heat-sensitive part to the air. Furthermore, since it is a waterproof and sealed structure, the structure is complex, but performance and reliability are always issues. Therefore, an object of the present invention is to provide an aquarium in which temperature can be accurately detected without impairing the appearance of the aquarium or being affected by the water level.

As shown in FIG. 4, the lid body 4 has a bracket 52 protruding from one side thereof and a hinge 53, and air circulation holes 54 are arranged in a circular shape on the surface. A plurality of support springs 55... are provided on the inner surface of the lid body 4, a ring-shaped crab light lamp 66 is attached to the support springs 55..., and a moisture-proof cover 57 with good transmittance is attached to cover the lamp 56. It is being
The upper part of the furnace tank 38 is located at the center of the inner surface of the lid body 4 .
Water is supplied to the aquarium container 3 by opening the lid 7 of the aquarium 1 constructed as described above.

The maximum water surface mark is near the inverted Y-shaped water guide 37 provided on the circulating flow generator 33. The fish F is a space surrounded by the inner surface of the aquarium container 3 and the tapered surface of the partition 10 of the inner tube 27, that is, the aquatic fish section 58. By supplying water to the aquarium section 58, the pump device 15 is submerged in water through the circulation suction row 3, and is in a state where priming water is supplied. Then, water is circulated within the water tank 1 by operating the pump device 15 (the driving means will be described later). The circulation route is as shown in FIG. 13 (indicated by arrows in FIG. 4).

That is, when the pump device 15 operates, water is pumped from the pump device 15 to the discharge pipe 28. At the upper end of the discharge pipe 28, the baffle plate 5 collides with the water and sprays water in all directions,
Water is sprinkled on 8. In the furnace tank 38, it passes through the filter tank 48,
It permeates through the furnace plate 46 and reaches the guide cylinder 42 via the drainboard 44. At this time, air cannons are mixed into the flowing water at the air cannon inlet 40a as in the case of the spray structure due to the flow of water (FIG. 6). When the water exits the guide tube 42, it falls into the inner tube 27. In the inner cylinder 27, the overflow notch 31 is overflowed and the aquatic part 58 is formed.
flows into. At this time, when the lever 36 of the circulating flow generator 33 is operated to release the inverted Y-shaped water guide 37 from the notch 31 as shown in FIG. 10a, the water will fall vertically downward from the notch 31.
In the aquatic part 58, a flow that circulates in a U-shape from the inside to the outside is formed as shown by the arrow in FIG. Furthermore, when the water guide 37 is positioned as shown in FIG. 10b, water flows down along the tapered surface of the guide, and a falling component in the tangential direction of the inner cylinder 27 is added. The outer peripheral surface of 27 is spirally wound. Furthermore, if the water guide 37 is configured as shown in FIG. 10c, the spiral direction will be reversed. In the fish section 58, the water flows through the circulation passage 14 through the circulation suction port 13 at the bottom and is sucked into the inflow passage 17 of the pump device 15. To drain water from the water tank 1, open the lid 4, remove the baffle plate 50, connect a hose (not shown) to the upper end of the discharge pipe 28, operate the pump device 15, and drain most of the water. It is convenient to tilt the container 3 and water the chicks.

In addition, the excreta and remaining food fed to the fish by opening the lid 4 and cultivated by the fish in the aquatic fish section 68 fall onto the tapered surface of the partition table 10 and flow into the circulating water of the aquatic fish section 58. It naturally moves to the circulation suction port 13 and is introduced into the furnace filtration tank 38 by the pump device 15, where it is purified.

That is, in the furnace tank 38, the solids are physically separated by the filter 48. Next, in the furnace material 46, aerobic decomposition bacteria and nitrifying bacteria that are attached to the surface of the furnace material 46 perform biological oxidation of organic matter such as feces, leftover feed, and ammonia, and nitrify it to harmless nitrogen compounds such as nitrate nitrogen. be done. This nitrogen compound becomes fertilizer for aquatic plants. The fresh water purified in this way flows back to the aquarium section 58. As a result, fresh water is always maintained in the aquatic fish section 58 for a long period of time. In addition, the solvent oxygen necessary for fish growth is constantly taken in by the carbonic acid assimilation effect of the aquatic plants 30, the mixture from the air bubble inlet 40a, the mixture when it falls from the filter 48 to the furnace material 46, and the mixture when it is scattered by the baffle plate 50. ing. Regarding heat retention when breeding tropical fish, which are said to be sensitive to temperature changes, when the tank overflows, the stainless steel heat receiving plate 8 provided on the bottom plate 5 of the aquarium container 3 receives heat from the outside (the heating means will be described later). Heat is added to the kasu water.

The heat receiving plate 8 is located within the circulation passage 14, and the circulation passage 1
4 flows from the circular circulation suction port 13 to the central inflow passage 17 in a radial direction straight or in a spiral shape (when a circulating flow is formed by the water guide 37), so water flows in a part of the passage 14. Even if the water is heated, it is uniformly heated while flowing through the pump device 15 that collects the water and the discharge pipe 28, and when it is supplied to the aquatic fish section 53, the temperature is completely distributed. Therefore, the temperature gradient allows flooding without affecting the fish. On the other hand, temperature control for keeping the water temperature constant is controlled by a temperature sensor, which will be described later, via a sensor heat transfer plate 9. crab light lamp 5
The illumination by 6 is transmitted through and reflected from the moisture-proof cover 57, the water surface, the inner cylinder made of transparent material, and the peripheral wall 6 of the aquarium container 3, so that the aquatic plants 30 and the fish F can be seen brightly from the outside of the aquarium 1.

The light heat of the lamp is radiated through the air circulation holes 54 of the lid 4.
Next, Hagi Rekidai 2 will be explained.

As shown in FIGS. 3 and 4, the mounting table 2 has a hollow cylindrical shape with a height smaller than its diameter, and has a positioning rib 59 on the upper circumferential portion thereof that fits inside the lower end portion of the circumferential wall 6 of the water tank portion 1. are formed, and holes 61 to 64 are formed in the upper plate 601 of the layering table 2 corresponding to the non-magnetic plate 7 of the bottom plate 5 of the aquarium container 3, the heat receiving plate 8 made of stainless steel, and the sensor heat transfer plate 9. There is. A drive device 65 is provided in the hole 61, a heater device 66 is provided in the hole 62, a ballast 67 for the crab light lamp is provided in the hole 63, and a temperature sensor 68 is provided in the hole 64. First, as shown in FIG. 5, the drive device 65 is composed of a motor 69 and a rotating drive-side permanent magnet 71 attached to the motor shaft 701. The upper part of the permanent magnet 71 is covered with a waterproof coating with a thin drive head 71a. . The driving head 71a of the driving device 65 is exposed to the outside of the upper plate 60 through the hole 61, and the entire driving device 65 is suspended and supported by the upper plate 60 by a tension spring 72 as shown in FIG. The head 71a is floated above the upper plate 60. The heater device 66 includes a positive temperature characteristic heater covered with a waterproof heater head 66a that is electrically insulating and has a low thermal resistance, and the entire body is suspended from an upper plate 6 by a tension spring 73, positioned by a protrusion 66b, and the head 66a is inserted into a hole. It is more popular than 62. Stabilizer 6
7 is similarly covered with a waterproof coating by a head 74 and floats from the hole 63. The ballast 67 is used as an auxiliary heating source for the aquarium section 1. Furthermore, as shown in FIG. 14, the temperature sensor 68 has a heat insulating material 76 lined on the inner surface of the sensor housing 75 to waterproof the sensor head with good heat conductivity, and a sensor element 7 on the bottom surface of the sensor head.
8, the sensor housing 75 is suspended by a tension spring 79, positioned by the protrusion 75a, and the sensor head 7 is
7 is floating from the hole 64. As shown in FIG. 3, a drain hole 80 is formed in the upper plate 6, and as shown in FIGS. There is.

As shown in FIG. 3, a protruding part 83 is provided on one side of the number stand 2, a recessed part 84 is formed in the upper surface of the protruding part 83, and a receiving blade 85 for an outlet or the like is buried in the bottom of the recessed part 84.

In this recess 84, a lower end portion of a lighting support 86 is erected with iron. The illumination support 86 is provided with a plug blade 87 such as an insertion plug on the lower end surface, and when the support 86 is iron-bonded, the plug blade 87 is inserted into the receiving blade 85 and electrically connected. A cord 88 passes through the support column 86 and is connected to a socket 89 of the backlight lamp 56 of the lid body 4 from the upper end as shown in FIG. Further, the upper end of the support column 86 is connected to the hinge 53 of the lid 4, and
is rotatably supported by a column 86. On the upper side of the loading table 2, there is a notch 90 for cleaning the water tank, as shown in Fig. 3.
is formed.

As shown in FIGS. 3 and 4, a hole is formed on the side of the battle platform 2, and a cord bush 91 is attached thereto, and a power cord 9 is inserted into the hole.
2 is inserted. Further, a heater switch 93 and a lamp switch 94 are attached to the side surface. Furthermore, as shown in FIG. 4, a limit switch 95 is disposed below the heater device 66 within the range in which the heater device 66 moves.
Note that 96 is the leg of the counterfeit stand 2, 97 is the air circulation hole, and 98 is the electric block. The circuit diagram of the electrical wiring for this aquarium is the first one.
It is shown in Figure 7.

That is, a lighting circuit C including a halo lamp 56, a glow lamp 99, a noise prevention capacitor 100, a ballast 67, and a lamp switch 94, and a control circuit 101 that operates by controlling the heater of the heater device 66 and the temperature sensor 68. , a heater circuit C2 including a heater operation notification lamp (using a pilot lamp) 102 and a heater switch 93, and a motor circuit C3 of the motor 69 are each connected to a power source E (power cord 92). A power-on notification lamp (using a pilot lamp) 103 is further connected in parallel to the power cord 92, and circuits C, to C3 are connected in parallel.
A limit switch 92 is connected between the power supply side and the power supply side.
With this circuit configuration, when the aquarium part 1 is placed on the number table 2, the non-magnetic plate 7, the heat receiving plate 8 and the sensor heat transfer plate 9 on the bottom part 5 are exposed to the air floating from the upper plate 60 of the Hagi layer table 2. head 66a
, 71a, 74, and 77 are brought into close contact with each other, and the permanent magnets 25 and 71 are magnetically coupled to each other on the nonmagnetic plate 7, and the heat receiving plate 8
The heat exchanger plate 9 and the heads 66a, 74, 77 are thermally coupled. At the same time, the heater calendar 66 is pushed by the heat receiving plate 8 and moves downward, turning on the limit switch 92. As a result, when the power cord 92 is connected to the power source, the motor circuit C3 is closed and the motor 69 is driven, and the permanent magnet 71 rotates and the permanent magnet 25 of the aquarium part 1 is magnetically coupled to the motor circuit C3.
is driven and rotates the impeller 24 to operate the pump. Next, when the lamp switch 94 is turned on, the crab light lamp 5
6 lights up. At the same time, the ballast 67 generates heat, heats its head 74, transfers the heat to the heat receiving plate 8, and supplementally heats the water flowing through the circulation passage 14. When the heater switch 93 is turned on, the heater 66 generates heat to heat the head 66a, which is a heat transfer plate, and transfers the heat to the heat receiving plate 8, thereby heating the water flowing through the circulation passage 14. Since the heater has positive temperature characteristics, overheating is self-controlled. On the other hand, the temperature of the water flowing through the circulation passage 14 is transmitted to the sensor heat transfer plate 9 and then to the sensor head 77, and this temperature is detected by the temperature sensor 68. In this case, since the sensor head 77, the heater head 66a, and the head 74 are located in a direction perpendicular to the direction of water flow in the passage 14, the heated water is not immediately detected, and the circulation path always allows the aquatic fish to 58 water temperatures have been detected. Further, due to this circuit configuration, the limit switch 92 does not turn on unless the water tank 1 is positioned on the stacking table 2. The features of this tank are explained below.

That is, by using the '1' magnetic joint, the water tank section 1 containing the pump device 15 and the mounting table 2 containing the drive device 65 of the pump device 15 are completely separated with respect to water, and the water tank section 1 and the counterfeit table are completely separated. 2 is removable, so
The problem of electric leakage and electric shock has been resolved, and the water in the tank 1 has been changed.
There is no need to consider electrical parts during cleaning, making it safe and easy to operate. In particular, by providing a cut-out recess 90 in the tank base 2 and supporting the bottom of the aquarium container 3 by inserting your hand therein, it can be easily removed and placed next to the aquarium container 3, and the appearance is also improved compared to the case where the handle protrudes from the aquarium container 3. Are better. Furthermore, by providing a positioning rib 59 on the upper periphery of the Atsushi pupil stand 2 that joins to the inside of the lower end of the peripheral wall 6 of the aquarium section 1, drops traveling along the outer surface of the aquarium container 3 can be prevented from entering the upper surface of the calendar stand 2. can be prevented. By providing a drain hole 80 on the top surface of the battle platform 2, water collected on the top surface can be safely removed. ■ The inner cylinder 27 is provided in the aquarium container 3 to form the aquatic fish part 58, and the inner cylinder 27
Since the furnace tank 38 and the pump device 15 are provided above and below, respectively, the fish can be seen from above the outside of the aquarium 1, expanding the viewing range and improving the aesthetic appearance.

Since the upper part of the container 3 is closed, it is easy to administer food, and since water is circulated within the aquarium 1, there is no splashing of water to the outside and it is difficult for water to splash on the container. In particular, a partition 10 is provided at the bottom of the aquarium container 3, and this allows a narrow circulation inlet 1.
3 and the circulation passage 14 are formed, the flow rate passing through this part is high, and dirt, feces, etc. can be reliably transferred to the furnace tank 38.
Further, the heating of the water through the heat receiving plate 8 can be quickly transmitted to the entire inside of the pot. Note that the aquarium container and the inner cylinder may be square cylinders. By providing the circulation suction row 3 at the bottom, which serves as an outlet for filtering the dregs water from the lake and fish section 58, the water and fish section 58
It is possible to reliably transport garbage that has sunk to the bottom of the water.

This is particularly effective because the upper surface of the partition table 10 is tapered toward the circulation suction port 13. This reduces the amount of dirt adhering to the walls and reduces the number of water changes. Furthermore, the design can be changed so that the water flow can be easily guided to the circulation passage 14 by directing the suction port 13 toward the tapered surface of the partition 10 as shown in FIG. In addition, by doing this, it becomes difficult for fish to approach the circulation suction port 13 due to their habits, and it is possible to prevent the fish from being sucked in and dying by accident. The inlet 13 is also the second
As shown in Fig. 0 and Fig. 21, radial grooves 13' (width of about 1 to 2 willows, length of about 5 to 15 skins) are formed in the peripheral green part of the partition stand 10.
This facilitates the movement of solid matter such as feces and leftover food. '41 Since the baffle plate 50 is detachably provided at the upper end of the discharge pipe 28, the water discharged from the discharge pipe 28 collides with the baffle plate 5, scatters in all directions, and falls onto the furnace tank.

At this time, the water is sprinkled, so there is an effect of taking in dissolved oxygen and a visual effect. In particular, when the surface of the baffle plate 50 that the water collides with has an uneven shape, the visual effect becomes remarkable. A stainless steel sensor heat transfer plate 9 is formed on the bottom plate 5 of the water tank container 3, and a sensor head 77 with good heat transfer is formed on the outer surface of the stainless steel sensor heat transfer plate 9.
is arranged, the sensor element 78 is arranged through this, and the element 7
Since the periphery of the aquarium 8 is covered with a heat insulating material 76, only the water temperature in the aquarium container 3 can be detected, and even a drop in the water level can be detected. Therefore, compared to the case where the sensor is placed underwater, there is no need to consider waterproofness, the beauty of the aquatic fish area is not spoiled, and the reliability of the sensor is improved. Note that the heat transfer plate 9 does not need to be made of a metal material, and a part of the resin bottom plate 5 may be made as thin as possible to improve thermal efficiency. {6) Air introduction pipe 40' guide tube 42
Since the air mixing inlet 40a is formed in the inner cylinder 27, air bubbles are mixed in when water enters the inner cylinder 27, and there is a visual effect due to the intake of existing oxygen and the movement of the air bubbles.

'7} By providing the water guide 37 on the exit side (aquatic capital side) of the overflow notch 31 that conveys the inner cylinder 27 with aquatic plants and the aquatic fish section 58, a circulation flow can be formed in the aquatic fish section, and the fish can flow in the same direction. It is possible to create an environment that is in line with people's habits.

In particular, if the lever 36 is used to change the direction of the flow or create a state in which there is no flow, the swimming of the fish can be controlled at will. '8) Since the annular crab light lamp 56 suspended from the lid 4 is disposed above the aquatic fish section 58, the aquatic fish section 58 and the aquatic plants 30 are efficiently illuminated throughout the day on the water surface.

In this case, since the furnace tank 38 is located in the center of the crab light lamp 56, space can be used effectively and compactness can be achieved. '9} The circulation suction row 3 is provided at the bottom of the water tank 58, and the pump device 15 guides the sewage from the water tank 58 to the furnace tank 38 in the upper part, so that garbage and the like can be quickly collected and collected. In particular, since the furnace tank 38 is supported by an inner cylinder, the discharge pipe 28 can be made thinner, and even faster furnace heating is possible.
The three aquatic plants inside the inner cylinder 27 can be made to look larger due to the lens effect of the transparent cylinder, and the value as an interior item can be increased. (Aquatic plants are provided in the inner cylinder 27 of 1 to separate it from the aquatic fish part 58, and the circulating water is transferred from the inner cylinder 27 to the aquatic fish part 58.
Since it communicates with the aquatic plant 30 by overflow, dead leaves and cut branches of the aquatic plants 30 do not enter the aquatic part 58, and the inner cylinder 2
It can be stopped within 7.

Therefore, they will not enter the pump device 15, the circulation suction row 3, or the circulation passage 14 and cause clogging, causing the pump to malfunction. Further, the water mirror portion 58 is less contaminated and the garbage collection efficiency is also good. Furthermore, since fresh water subjected to bioreactor treatment in the furnace tank 38 is supplied to the aquatic plants 30, nutrients such as nitrogen compounds become fertilizer for the aquatic plants 30, thereby suppressing abnormal growth of phytoplankton. In addition, dissolved oxygen is supplied to the aquatic fish portion 58' due to the carbonic acid solidification effect of the aquatic plants 30. Since the inner cylinder 27 is removably attached to the partition stand 10', it is easy to care for the aquatic plants 30. In addition, as shown in FIG. 22, the inner cylinder 2
A lotus hole (small diameter) 105 communicating with the aquatic plant 58 can be formed at the bottom of the aquatic plant 7 to guide nutrient-rich water to the roots of the aquatic plants 30 to give glory to the roots. (11
) By going through the water circulation process as shown in Figure 13, water purification and oxygen supply can be efficiently achieved.

Since the furnace air tank 38 separates the physical furnace and biological furnace and performs the physical furnace first, the biological furnace is less likely to be clogged with garbage. At the same time, it is possible to take in oxygen on the way to the biological reactor. Since the furnace sandpaper 38 is placed at the upper end of the inner cylinder 27, it can be removed and cleaned easily. Baffle plate 5
Since water is uniformly distributed from the river to the filtration tank 38, filtration is performed evenly. (12) Heads 66a, 71a, 7
4 and 77 are floating on the upper surface of the drum base 2, and by layering the water tank part 1, they are securely brought into close contact with the bottom plate 5.

Therefore, magnetic coupling and heat transfer are ensured.
Therefore, on the contrary, precision is not required for the connection between the water tank part 1 and the battle layer stand 2. (13) The aquarium container 3 is made of a transparent material such as acrylic resin that is heat conductive, and the bottom plate 5 is made of stainless steel heat receiving plates 8 and 9 that are heat conductive.
Because it is in close contact with the water, the accuracy of heating and detection of water temperature is high.

Also, since it is located in a position that is difficult to see from the outside, it does not spoil the appearance. (
The upper surface of the IQ stainless steel heat receiving plate 8 is covered with a partition stand 10 to prevent fish from coming to the upper surface of the heat receiving plate 8, thereby protecting the fish.

Moreover, cleaning can be easily performed by removing the partition stand 10. (15) Since the stabilizer 67 is used as an auxiliary water temperature heating source, heat is effectively utilized. Therefore, a heat dissipation space for the ballast 67 is not required. (16) Power cord 9 to Dunrekidai 2
2 is inserted, and a receiving blade 85 such as an outlet is provided on the Dungeon stand 2, and current is supplied to the lamp 56 of the lid body 4 via the lighting support 86.

Therefore, the external wiring is simple and unobtrusive, and the appearance is improved.
