DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquarium filtration device installed in an aquarium for ornamental breeding of aquatic organisms such as goldfish and tropical fish for purifying water.

[0002]

2. Description of the Related Art In recent years, an aquarium tank for aquarium fish, which is preferably used as an interior of a room, in which a filtering device and an illuminating device are arranged above the aquarium and which are covered with a top cover, is well known. .

[0003] In this type of aquarium, by arranging various devices such as a filtering device and a lighting device in the top cover efficiently, a limited space in the top cover is effectively used to ensure a good appearance. In addition, a predetermined filtering ability and a lighting effect are obtained.

[0004]

By the way, a filtration device installed in a water tank as described above basically includes a filtration tank in which a filter medium is stored and a filter tank for supplying water in the water tank. Although a pump is provided with a pump, in order to improve the filtration capacity of this filtration device, a method of installing a large pump or a large filtration tank, or a method of installing a plurality of pumps and filtration tanks is generally considered. .

[0005] However, in this case, the size of the entire filtering device becomes large, and it becomes difficult to install the filtering device in a limited space, for example, in a top cover of a water tank. For this reason, when the filtering device is installed outside the top cover, there is a problem that the filtering device is exposed and the appearance is impaired. In addition, a method of removing the peripheral device such as a lighting device inside the top cover to secure the installation space for the filtering device may be considered. This causes another problem that the function as a water tank is reduced.

In the above-mentioned conventional filtering apparatus, when performing maintenance work such as replacement of a filter medium or cleaning of a filtration tank, it is necessary to stop filtration of water during the maintenance work. As described above, there is a problem that there is a limitation in the use situation and good usability cannot be obtained.

[0007] The present invention solves the above-mentioned problems of the prior art, can improve the filtration ability, and can further reduce the size, and can be installed in a water tank without restriction on peripheral devices. It is an object of the present invention to provide an aquarium filtration device that can obtain good aesthetic appearance, can be filtered even during maintenance work, and can obtain good usability.

In the filter device for a water tank according to the present invention, a plurality of filtration chambers independent of each other are provided in the filtration tank, and the water pumped up by one pumping means such as a pump is diverted by the diversion means, and each filtration chamber is separated. Since the pumps and the filtration tanks are provided in parallel, for example, a large apparatus can be installed as a pump or a filtration tank, or the apparatus size can be formed more compact than when a plurality of pumps or filtration tanks are installed. .

Further, the filtering device of the present invention can efficiently filter water by a plurality of filtering chambers.

In the case where the maintenance work of the filtration chamber is performed, during the maintenance work of one of the filtration chambers,
In the remaining filtration chamber, water can be filtered.

On the other hand, in the present invention, downstream chambers communicating with the respective filtration chambers are provided on the downstream side of the plurality of filtration chambers, respectively, and the discharge ports are provided in these downstream chambers, respectively. At least one of the downstream chambers is provided with intermittent discharge means for intermittently discharging water from the discharge port, and a lower end of the downstream chamber provided with the intermittent discharge means has a lower end below the water surface in the water tank. It is preferable to adopt a configuration in which a watering prevention pipe located at a position is mounted.
