[Prior art]

 If you keep a goldfish or a tropical fish in the aquarium for a while, the water inside will be contaminated by food waste and droppings. Therefore, a water purification device for appreciation has been developed in which a filtering device for removing dirt from the water in the aquarium is installed on the upper part of the aquarium. The filtering device is equipped with a filtering device, a pump for sucking the water in the water tank into the filtering tank, and a drive motor for the pump.The pump is operated by the driving motor to suck the water in the water tank into the filtering tank. Is filtered by the filtering material stored in the filtration tank and returned to the water tank again. The conventional drive motor is disposed on the upper part of the pump in an externally exposed state in order to release the drive heat of the motor to the atmosphere.

[0003]

[Problems to be solved by the device]

 However, in the conventional water purification system for appreciation, the drive motor is placed on the upper part of the pump in such a state that it is exposed to the outside, so the motor rusts due to the moisture evaporating from the water surface of the aquarium, and the durability is poor. Moreover, for example, if you try to view saltwater fish such as sea bream or flatfish by replacing the water in the aquarium with seawater, salt content in seawater will adhere to the drive motor, further reducing the durability of the motor. . This was one of the major reasons why the saltwater fish could not be kept in a domestic aquarium. In addition, these problems become particularly noticeable in the case of a water tank with a lid, in which moisture in the water tank does not easily leak to the outside. In addition, in the case of this aquarium with a lid, the upper part of the aquarium is covered by the lid, so that water droplets tend to adhere to the upper wall of the aquarium and the inner surface of the lid due to moisture, so that the fish in the aquarium can be seen. It was annoying, and it was troublesome to wipe off water droplets when cleaning the water tank. The present invention has been made in view of such circumstances, and it is possible to improve the durability of the drive motor of the filtration device, to view not only freshwater fish but also saltwater fish, and to improve ventilation in the upper part of the aquarium. The purpose is to provide a water purification device for appreciation.

[0004]

[Means for Solving the Problems]

 The water purifying apparatus for appreciation according to claim 1, which is in accordance with the above object, comprising: a filter tank above the water tank; a supply means for supplying the water in the water tank to the filter tank; and a drive motor for driving the supply means. In a water purifying apparatus for appreciation in which a filtering device having the above is installed, the drive motor is sealed in a casing, a fan is provided in the casing, and a ventilation pipe communicating with the outside of the water tank is provided in the casing. There is. The appreciation water purifier according to claim 2 is the appreciation water purifier according to claim 1, wherein the exhaust port of the ventilation pipe is arranged in an upper portion of the water tank.

[0005]

[Action]

 In the water purifying apparatus for appreciation according to the first aspect, when the drive motor is driven to supply the water from the water tank to the filtration tank by the supply means, the supplied water is filtered in the filtration tank and then returned to the water tank. At this time, the drive heat of the drive motor is generated in the casing that houses the drive motor, but this heat passes through the ventilation pipe by the fan in the casing and is discharged to the outside. Heat does not accumulate. In addition, since the drive motor is housed in the casing, the water in the water tank does not impinge on the drive motor when the water is replaced or the water tank is cleaned. Particularly, in the water purifying apparatus for appreciation according to claim 2, when the drive motor is driven to rotate the fan, the wind generated by the fan is blown out from the exhaust port of the ventilation pipe into the upper part of the water tank, and the moisture in the water tank is dried. By forcing the charged air out of the aquarium to ventilate it, it is possible to prevent the formation of water droplets that adhere to the upper wall of the aquarium.

As shown in FIG. 2, the water purification device 10 for appreciating freshwater fish, brine fish, and tropical fish according to one embodiment of the present invention has a front surface and both side surfaces that are gently continuous and integrally formed of acrylic resin. It has a water tank 11. The water tank 11 is placed on a stand 12, and a lid stand 14 is attached to the upper part of the water tank 11 via a frame 13 having a frame shape. A large number of ventilation holes 13a for ventilating the inside of the water tank 11 are provided on the front surface of the frame 13, and ventilation holes 14a are also provided at the rear corners of the upper portion of the lid base 14. A large opening 14b is provided at the front of the lid base 14, and a lid 15 is attached to the opening 14b so as to be openable and closable. Next, the devices provided in the water purification device for viewing 10 will be described in detail with reference to FIG.

As shown in FIG. 1, a mounting frame 16 is laid across the center of the frame 13, and a filtering device 17 is mounted on the mounting frame 16. The filtering device 17 has a horizontally long filtering tank 18 arranged above the water tank 11. Inside the filtering tank 18, a filtering material 20 having a filter bacterium adhered to its surface is placed in a case 19. The tank 18 is stored close to one end side. As the filtering material 20, the filtering material described in Japanese Patent Application Laid-Open No. 3-146106, which was previously filed and filed by the present inventor, is used. This is a filter medium manufactured by mixing granules by mixing shell powder, sawdust, diatomaceous earth and an appropriate amount of binder with the main component, shirasu powder, and firing the granules. It has the characteristics that live fish can be kept alive for a long period of time by neutralizing and alkalizing the acidic substances in the water and adsorbing odors such as ammonia in water to purify the water.

On one end side of the filtration tank 18, a pump 21 is provided as an example of a supply means for sucking the water in the water tank 11 into the filtration 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 portion 22 and a drive portion 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 as follows. In a water storage cylinder 24 having a lid 24a screwed onto the open upper portion, the lower end is fixed with the upper end of a slender lower pipe 25 having a small diameter inserted below the water surface of the water tank 11. It is arranged. A fan case 26a for housing the fan 26 is connected to the peripheral surface of the water storage cylinder 24 via a connecting pipe 22a. 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 of the upper pipe 27 is inserted into the filtration tank 18 through a hole 28a formed in the lid 28 of the filtration tank 18, and the lid 28 prevents odor and dew condensation in the filtration tank 18. A plurality of ventilation holes 28b are formed (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. An intake pipe 31a, which is an example of a ventilation pipe having a tip portion communicating with the opening 14c of the lid base 14, is connected to the upper surface of the casing 23a on the drive motor 29 side, and the housing portion 23b of the casing 23a is also connected. An exhaust pipe 31b as an example of a ventilation pipe communicating with the opening 14d of the lid base 14 is connected to the side surface on the side. When the drive motor 29 is driven, the water suction fan 26 rotates, and the water previously stored in the water storage cylinder 24 and the fan case 26a flows into the upper pipe 27. 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. Due to this negative pressure, the water in the water tank 11 is sucked up into the water storage cylinder 24 from the thin lower pipe 25. To be 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, and air is sucked into the casing 23a from the outside through the intake pipe 31a. Air cooled. Thereafter, the air is exhausted from the storage portion 23b to the outside through the exhaust pipe 31b and the opening portion 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 casing 33 of the siphon means 32 is a cylindrical container body having an open lower surface, and is provided with an intake cylinder 34 that is substantially semicircular in cross section on the peripheral side surface of the casing 33. The upper end of the intake cylinder 34 communicates with the upper portion of the casing 33, and the lower end of the intake cylinder 34 has a height position W. Height position E.L above width L by width d. It is located at L. In the casing 33, a small-diameter drain pipe 35 for discharging the filtered water into the water tank 11 is supported by a support frame 36. The upper end of the drainage pipe 35 is flush with the lowest position of the outlet 34b of the intake pipe 34, and the lower part of the drainage pipe 35 is inserted into an opening 18a formed in the other end of the filtration tank 18. It extends downward.

As shown in FIG. 1, a horizontally long base 38 is attached to the back surface of the lid base 14, and the switch 39 is turned on and off to operate and stop these devices. 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 numeral 34 a denotes an inlet of the intake cylinder 34, and reference numerals 42 to 44 denote mounting holes for the filtration tank 18, the pump 21, and the heater 37 provided in the mounting frame 16.

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. Since the water tank 11 is provided with a stand 12 at the bottom, it can be placed on a stiff box, which is difficult to place in the past, because it may be corroded by water droplets adhering to the lower surface of the water tank 11. The range of storage places can be expanded. The water in the water tank 11 is heated by the heater 37 to a predetermined temperature at which tropical fish can easily survive. Ventilation in the water purification device 10 for appreciation is performed by circulating air through the ventilation holes 13a and 14a.

As shown in FIGS. 3 and 4, the pump 21 is actuated by the driving of the drive motor 29 so that the water in the water tank 11 is always passed through the upper and lower pipes 25 and 27 to one end of the filtration tank 18. It is dropped on the filter material 20. At this time, 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. 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, and the durability of the motor 29 is improved. It is possible to put saltwater fish, which is difficult to keep in a domestic aquarium, into seawater 11 by putting saltwater into the aquarium 11.

The water filtered by the filter material 20 is gradually stored in the filter tank 18. At this time, as shown in FIG. 5, as the filtered water level rises, the casing 33 of the siphon means 32 and the intake pipe 34 also have an opening on the lower surface of the casing 33 and an inlet of the intake pipe 34. Flows gradually from 34a. Then, this water level is the height position W. When the water reaches H and completely closes the opening at the upper end of the drain pipe 35, 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.

After that, the water level is changed to the height position W.W. Although the water level gradually drops to L, the water surface is in the middle of the height position E.E. of the inflow port 34a at the lower end of the intake cylinder 34. Passing position L. When it approaches L, the filtered water discharged from the drain pipe 35 is in a delicate state in which air and filtered water are mixed and the siphon is cut or not cut. At this time, the inflow port 34 a of the intake cylinder 34 is positioned at the height position W. Position E. higher than width H by width d. Since it is at L, only air flows from the inflow port 34a through the intake cylinder 34 and flows into the casing 33, and this air completely shuts off the siphon.

Then, the filtered water is gradually stored again in the filtering tank 18, and the same operation is repeated until the drive motor 29 of the pump 21 is stopped. At this time, since the filter medium 20 is repeatedly brought into contact with the outside air or immersed in water, the filter bacteria attached to the filter medium 20 can directly take in oxygen from the outside air when the water level is lowered, and When the pressure drops and rises again, the amount of oxygen adhering to the filter medium 20 can be taken into the water by the amount of the surface area of the filter medium 20. As a result, the filtration bacteria can be activated to promote the filtration of the water in the water tank 11, and sufficient oxygen can be given to the tropical fish in the water tank 11.

When observing the tropical fish in the aquarium 11, the aquarium 11 has sharp corners, so it is easy on the eyes and, like a conventional angular aquarium, the corners on both sides when viewed from the front are good. It is difficult to form blind spots, the water flow is smooth, the migration of tropical fish becomes natural, algae, moss and dirt are not easily attached to the corners, and the inside of the tank is easy to clean. Moreover, since the water tank 11 is integrally molded from acrylic resin, the water tank 11 has a high strength, is less likely to be deteriorated, discolored, or cracked by sunlight, is durable, has a high transparency, and has a conventional water tank. As in the case where the wall surfaces are adhered at the corners like this, there is no risk that the adhered parts will peel off and the water inside will leak. Further, since the filter medium described in Japanese Patent Laid-Open No. 3-146106 is used as the filter medium 20, the water filtering action is further improved, and the water tank 11 is less frequently replaced or cleaned. . 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, saltwater, which may damage the motor due to salt content, can be put in the aquarium 11 to keep saltwater fish that are 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 examples, the aquarium for freshwater fish, brine fish, and tropical fish was illustrated, but the present invention is not limited to this and can be applied to any other types of aquarium. Further, in the examples, the filter medium described in JP-A-3-146106 was adopted as the filter medium, but the filter medium is not limited to this, and any other filter medium may be used. Further, as the supply means, a pump for sucking is adopted, which is 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 present inventor. However, it is not limited to the above, and various other kinds of supply means such as various general pumps and a pumping type for elevating and lowering a water trough material may be used. 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 casing is maintained in a sealed state, and a fan is provided on this projection to form an intake hole in the frame. The ventilation holes in the water purification device for appreciation may be forcibly forced by the exhaust holes provided in the lid base to improve ventilation. Further, the exhaust port of the ventilation 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 a chain line in FIG. By doing so, the wind generated by the rotation of the fan is blown out from this exhaust port into the water tank, and the moisture-containing air in the water tank is removed from the ventilation holes formed in the frame and lid. Forced out to the outside. This improves ventilation in the upper part of the water tank and prevents water droplets from adhering to the upper wall of the water tank or the inner surface of the lid. Also, since the exhaust port faces downward, even if the exhaust port is placed inside the water tank, it is difficult for water droplets and the like to enter the casing of the pump.

[0022]

[Effect of device]

 In the water purifying apparatus for appreciation according to claim 1, the drive motor of the filtration device is thus sealed by the casing to prevent the drive motor from moisture, so that the durability of the motor can be improved, and not only the freshwater fish can be used. You can also watch the saltwater fish. In addition, since the drive heat of the drive motor inside the casing is radiated to the outside from the ventilation pipe by the fan, even with the motor sealed inside the casing in this way, it is possible to sufficiently cool the motor. There is no harmful effect such as burning out. Particularly, in the water purification apparatus for appreciation according to claim 2, when the drive motor is driven and the fan rotates, the wind generated by the fan is blown out from the exhaust port of the ventilation pipe into the upper part of the water tank to remove the moisture in the water tank. By forcing the entrained air to the outside of the aquarium for ventilation, it is possible to prevent the generation of water droplets adhering to the upper wall of the aquarium.
