BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purification device for appreciation, and more specifically, it can increase the amount of oxygen taken into the water to activate the filtration bacteria in the filtration tank, and also to the upper part of the water tank. The present invention relates to a water purification device for appreciation in which the air temperature in a water tank can be lowered by improving the ventilation of a space and removing the heat of vaporization of water by riding on air moving on the water surface.

[0002]

2. Description of the Related Art Some water tanks for appreciation have a filter tank disposed on the upper part thereof. The filter tank contains a filter material with aerobic filter bacteria attached to it, which absorbs the water in the water tank, filters it by the action of the filter bacteria, and returns it to the water tank. Is purifying water. Also, if goldfish or other fish for appreciation are kept in the aquarium for a while, the water inside will become dirty due to food waste and feces. Therefore, by operating the pump that sucks up the water in the aquarium, a filter is installed at the top of the aquarium to remove dirt from the water in the aquarium, and a fluorescent lamp is installed at the top of the aquarium so that the fish in the aquarium can be viewed beautifully. The water purification device for appreciation provided is known.

[0003]

[Problems to be Solved by the Invention] By the way, fish take in oxygen dissolved in water from the gill and breathe. However, unlike running water such as a river or the sea, since the water surface in the water tank hardly moves, the contact area with air is relatively small and the oxygen content in the water is small. Therefore, it is necessary to devise a device for increasing the contact area with the air as much as possible for a water purification device for raising ornamental fish. Further, since the filtration bacteria in the filtration tank are aerobic microorganisms, the larger the contact area with oxygen is, the easier it is to activate, and the degree of activation greatly affects whether the filtration property is high or low.

Furthermore, there is a problem that the heat of the motor provided in the suction pump and the heat of the fluorescent lamp are easily trapped in the upper space of the water tank, which raises the water temperature in the water tank.
In particular, the temperature rises to such a degree that the fish are weakened during the daytime in summer when the temperature rises. From this fact, how to properly ventilate the upper part of the aquarium is one of the points for raising fish in the aquarium when breeding goldfish and the like. The present invention has been made in view of such circumstances,
The amount of oxygen taken into the water can be increased, the filtration bacteria in the filter tank can be activated, the ventilation of the upper space of the water tank is improved, and the heat of vaporization of water is multiplied by the air moving on the water surface. An object of the present invention is to provide a water purifying apparatus for appreciation in which the water temperature in the water tank can be lowered by depriving it, and the siphon means for vertically moving the water in the water tank can be compactly configured.

[0005]

A method according to the above-mentioned object.
The water purification apparatus for appreciation described above is a filtration tank above the water tank, a pump for supplying water in the water tank to the filtration tank, a fluorescent lamp for illuminating the inside of the water tank, and the filtration tank in the filtration tank. In a hermetically sealed water purification device for appreciation provided with a siphon means for raising and lowering the water level, a frame-shaped frame that is attached to the upper end of the water tank and that has at least the filter tank and a fluorescent lamp mounted thereon, and A lid base having an opening with a lid formed on the front upper surface of the frame-shaped frame is provided, and a plurality of ventilation holes are laterally provided on the back of the upper surface of the lid base. The siphon means is formed so as to penetrate through the bottom of the filtration tank, and the upper water inlet thereof is a straight pipe located slightly below the upper limit water level of the filtration tank, and the filtration tank. While covering the drain pipe inside with a gap, It is supported by a plurality of vertical plate ribs provided around the drainage pipe, the bottom part is an open lower water intake port and is arranged with a small gap from the bottom part of the filtration tank, and the diameter is sufficiently larger than that of the drainage pipe. A large cylindrical casing and integrally attached to the side of the cylindrical casing,
An intake port is formed at a position slightly higher than the lower water intake port, and an upper part has an intake cylinder portion communicating with the cylindrical casing.

[0006]

In the water purifying apparatus for appreciation according to claim 1, the siphon means is provided in the filtration tank so that the water level in the filtration tank moves up and down, whereby the filter material contained in the filtration tank comes into contact with air. Then, in addition to taking in more oxygen attached to the filter medium in the water, by giving oxygen to the filter bacteria,
The filtration bacteria can be activated. Also, in the case of an aquarium with a lid,
The heat of operation of the pump and the heat of the fluorescent lamp are trapped in the upper space of the water tank and raise the temperature of the water in the water tank.

A filter medium 20 having a filter bacterium adhered to the surface thereof is housed in a case 19 inside the filter tank 18 while being brought close to one end side of the filter tank 18. As the filter medium 20, the filter medium described in Japanese Patent Application Laid-Open No. 3-146106, which was previously filed and filed by the inventor of the present application, is used. This is a filter medium produced by mixing shell powder, sawdust, diatomaceous earth, and an appropriate amount of binder with shirasu powder, which is the main component, to make granules, and then firing the granules. It has the characteristics that live fish can be kept alive for a long period of time by neutralizing or alkalizing acidic substances and adsorbing odors containing ammonia in water to purify water.

A pump 21 for sucking the water in the water tank 11 into the filter tank 18 is provided at one end of the filter tank 18.
Next, the pump 21 will be described in detail with reference to FIGS. As shown in FIGS. 3 and 4, the pump 21 includes a main body 2
2 and a driving unit 23. As the main body 22, a simplified self-priming tank attached in front of the pump described in the specification of Japanese Patent Application No. 3-76772 previously filed by the inventor of the present application is adopted. The specific configuration is such that the upper end of a small diameter slender lower pipe 25 whose lower end is inserted below the water surface of the water tank 11 is fixed in a water storage cylinder 24 in which a lid 24a is screwed onto an open upper portion. It is arranged.
The fan 2 is attached to the peripheral surface of the water storage cylinder 24 via the connecting pipe 22a.
The fan case 26a for housing 6 is connected. An upper pipe 27 is connected to the upper part of the fan case 26a to rotate the fan 26 and drop the sucked water into the filtration tank 18. The tip portion of the upper pipe 27 extends from the hole 28a formed in the lid 28 of the filtration tank 18 to the filtration tank 18
The lid 28 is provided with a plurality of ventilation holes 28b for preventing odor and dew condensation in the filtration tank 18 (see FIG. 1). The fan 26 is fixed to one end of a long shaft 29a of a drive motor 29 housed in one side of the casing 23a of the drive unit 23.

A housing portion 23b of a fan 30 for ventilating the casing 23a is defined inside the other side of the casing 23a, and the fan 30 is fixed to the other end of the shaft 29a of the drive motor 29. Also, casing 2

When the drive motor 29 is driven, the fan 2 for sucking up water
The water 6 stored in the water storage cylinder 24 and the fan case 26 a in advance flows into the upper pipe 27 by rotating 6. As a result, the water in the water storage cylinder 24 is sucked into the fan case 26a and the inside of the water storage cylinder 24 becomes a negative pressure, and this negative pressure causes the water in the water tank 11 to flow from the thin lower pipe 25 into the water storage cylinder 24.
It is sucked up inside. After that, the water in the water tank 11 is continuously sucked into the filtration tank 18 through the lower pipe 25, the water storage cylinder 24, the connecting pipe 22a, the fan case 26a, and the upper pipe 27. On the other hand, when the drive motor 29 is driven, the ventilation fan 30 in the casing 23a rotates, air is sucked into the casing 23a from the outside through the intake pipe 31a, and the drive motor 29 is air-cooled by this air. . After that, the air flows from the storage portion 23b to the exhaust pipe 31
b, exhausted to the outside through the opening 14d.

Returning to FIG. 1, a siphon means 32 for returning the filtered water to the water tank 11 when the filtered water reaches a predetermined water level is housed in the other end of the filtration tank 18.
Next, the siphon means 32 will be described in detail with reference to FIGS. The cylindrical casing 33 of the siphon means 32 is a cylindrical container body having an opened lower surface.
An intake cylinder portion 34 having a substantially semi-circular shape in a sectional view is provided on the peripheral side surface of the suction pipe 3. The upper end of the intake cylinder portion 34 communicates with the inside of the upper portion of the cylindrical casing 33, and the intake port 34 a formed in the lower portion of the intake cylinder portion 34 is a lower water intake port 33 of the cylindrical casing 33.
a height position W. A position higher than the height L by a height d. It is located at L. In the cylindrical casing 33, a small-diameter drain pipe 35 for discharging the filtered water into the water tank 11 is provided with the vertical plate ribs 3.
Supported by 6. Upper water inlet 35 of drain pipe 35
a has the same height as the upper end of the intake cylinder 34, and
The lower part of 5 has an opening 1 formed at the other end of the filtration tank 18.
It is inserted through 8a and extends downward.

As shown in FIG. 1, on the back surface of the lid base 14,
A horizontally long base 38 is attached, and the switch 39 is turned on.
When turned off, these equipments are activated and deactivated. A fluorescent lamp 40 is provided on the back surface of the base 38, and a transparent lamp cover 41 is attached below the fluorescent lamp 40.

In the figure, reference numerals 42 to 44 denote mounting holes for the filtration tank 18, the pump 21, and the heater 37 provided in the mounting portion 16. The heater 37 is used as necessary when the water temperature becomes particularly low.

Next, the operation of the water purification device 10 for viewing according to one embodiment of the present invention will be described. Water, tropical fish, etc. are put in the aquarium 11, and the water purification device 10 for appreciation is placed at an arbitrary place such as on a grate box. Aquarium 11 is placed at the bottom 12
Since the water tank 11 is provided, the water tank 11 can be placed on a stiff box or the like, which may be corroded by water droplets attached to the lower surface of the water tank 11, and the range of the place for placing the water tank 11 can be expanded. . Ventilation in the water purification device 10 for appreciation is performed by circulating air through the ventilation holes 13a and 14a. That is, in the case of the water tank 11 with the lid 15, the operating heat of the pump 21 and the heat generation of the fluorescent lamp 40 are trapped in the upper space of the water tank 11 to raise the water temperature in the water tank 11, but the lid stand at a relatively high position. A plurality of ventilation holes 14a arranged on the back of the upper surface of 14 discharges high temperature air and water vapor inside using a draft. It should be noted that the intake air has a gap between the water tank 11 and the frame-shaped frame 13, a gap between the frame 13 and the lid stand 14, and a ventilation hole 13 a of the frame 13.
Etc. As a result, the ventilation of the upper space of the water tank 11 is improved, the heat of vaporization of the water is taken by being taken by the air moving on the water surface, and the temperature of the water in the water tank 11 can be lowered even slightly.

As shown in FIGS. 3 and 4, the pump 21 is actuated by the drive of the drive motor 29 so that the water in the water tank 11 is constantly filtered through the upper and lower pipes 27 and 25 at one end of the filtration tank 18. It is dropped on the material 20. At this time, the casing 2
The heat of the drive motor 29 accumulated in 3a is absorbed by the intake pipe 31a.
Is discharged from the exhaust pipe 31b to the outside together with the air sucked into the casing 23a. In this way, since the drive motor 29 can be completely partitioned from the water tank 11 side by the casing 23a, there is no fear that the drive motor 29 will be rusted by moisture, the durability of the drive motor 29 is improved, and, for example, the content of the drive motor 29 is increased. It is possible to keep saltwater fish, which was difficult to keep in a domestic aquarium, by putting even seawater, which is likely to cause a motor failure due to salt content, in the aquarium 11.

The water filtered by the filter medium 20 is gradually stored in the filter tank 18. At this time, as shown in FIG. 5, as the water level of the filtered water rises, the siphon means 32
It also gradually flows into the cylindrical casing 33 and the intake cylinder portion 34 from the lower water intake 33a of the cylindrical casing 33 and the intake port 34a of the intake cylinder 34. Then, this water level is the height position W. When reaching H, the upper inlet 3 of the drain pipe 35
When it exceeds 5a, the water in the filtration tank 18 is sucked into the drain pipe 35 at once by the siphon action, and is dropped into the water tank 11 from the water outlet at the lower end.

Thereafter, as the filtered water is discharged, the water level changes to the height position W.W. of the lower water inlet 33a of the cylindrical casing 33.
The water surface gradually descends toward L, but in the middle of the process, the water surface is at the height position E.E. After passing L, the filtered water discharged from the drainage pipe 35 is a mixture of air and filtered water. At this time, the intake port 3 of the intake cylinder portion 34
4a is a height position W.W. of the lower water inlet 33a of the tubular casing 33. A position higher than the height L by a height d. Because it is in L,
Air flows into the cylindrical casing 33 through the intake port 34a, and the siphon is completely cut off.

Then, the filtered water is gradually stored again in the filtering tank 18, and the same operation is repeated until the driving motor 29 of the pump 21 is stopped. At this time, the filter material 2
Since 0 repeats the operation of contacting with the outside air or being immersed in water, the filter bacteria adhered to the filter medium 20 can directly take in oxygen from the outside air when the water level drops, and the water level drops and rises again. At this time, the oxygen adhering to the filter medium 20 can be taken into the water by an amount corresponding to the surface area of the filter medium 20. As a result, it is possible to activate the filtering bacteria to accelerate the filtration of the water in the water tank 11, or to give sufficient oxygen to the tropical fish in the water tank 11.

When observing tropical fish in the aquarium 11, since the aquarium 11 has sharp corners, it is easy on the eyes and, like a conventional angular aquarium, the corners on both sides when viewed from the front. It is difficult to form blind spots, the water flow is smooth and the migration of tropical fish is natural, algae, moss and dirt are not easily attached to the corners, and the tank is easy to clean. Moreover, since the water tank 11 is integrally molded with acrylic resin, the strength of the water tank 11 is high, and there is little deterioration, discoloration, cracks, etc. due to sunlight, and durability is high. Unlike the case where the wall surfaces are adhered at the corners, there is no risk that the adhered portions will peel off and the water inside will leak. Also,
Since the filtering material described in Japanese Patent Laid-Open No. 3-146106 is used as the filtering material 20, the filtering action of water is further improved, and the frequency of water replacement and cleaning of the water tank 11 is reduced. Further, the heat of the drive motor 29 accumulated in the casing 23a is exhausted to the outside from the exhaust pipe 31b together with the air sucked into the casing 23a from the intake pipe 31a, so that the drive motor 29 is sealed by the casing 23a. Since it is completely partitioned from the aquarium 11 side, for example, salt water that may damage the motor due to the salt content can be put in the aquarium 11 to keep a saltwater fish that is difficult to keep in a domestic aquarium.

The present invention is not limited to this embodiment, and even if there is a design change within the scope of the invention, it is included in the present invention. For example, in the embodiments, the aquarium for freshwater fish, brackish fish, and tropical fish is illustrated, but the present invention is not limited to this and can be applied to any other types of aquarium. In addition, in Examples, as a filtering material, Japanese Patent Application Laid-Open No. 3-1
Although the filtering material described in Japanese Patent No. 46106 is adopted, the filtering material is not limited to this and any other filtering material may be used. Further, as a supply means, a suction pump provided with a self-priming tank attached in front of the pump described in the specification of Japanese Patent Application No. 3-76772 filed by the inventor of the present application was adopted. However, the supply means may be any general type, such as various general pumps or a pumping type pump for raising and lowering a water trough. Furthermore, the siphon means is not limited to that of the embodiment, and may have any other siphon structure.

Further, in the embodiment, the shaft of the drive motor is projected above the casing in a state where the sealed state of the casing is maintained, and a fan is provided at this projecting portion.
Ventilation may be improved by forcibly performing ventilation in the water purifying apparatus for appreciation by the intake hole provided in the frame and the exhaust hole provided in the lid base. Further, the exhaust port of the exhaust pipe extending from the casing of the pump to the lid may be arranged so as to face downward in the upper part of the water tank, as shown by the chain double-dashed line in FIG. By doing so, the wind generated by the rotation of the fan is blown out into the water tank from this exhaust port, and the moisture-containing air in the water tank is discharged to the outside of the water tank through the ventilation holes formed in the frame and lid. Force to push. As a result, the ventilation in the upper part of the water tank can be improved, and the generation of water droplets attached to the upper wall of the water tank or the inner surface of the lid can be prevented.
Further, since the exhaust port faces downward, even if the exhaust port is arranged in the water tank, it is difficult for water drops and the like to enter the casing of the pump.
