[0010]

However, when the filter tank 5 is filled with a light granular filter medium such as activated carbon or ceramic balls, the filter medium for filtering is originally a water flow, depending on the installation direction and the direction of hot water flow. There is a disadvantage that the dirt attached to the filter medium drops or fine powder of the filter medium is formed, and the hot water 2 in the bathtub 1 is contaminated by the dirt dropped from the filter medium and the fine powder of the filter medium. Was.

That is, when the filtration tank 5 is installed in the vertical direction and hot water flows from top to bottom, even if the filter medium is filled with a light granular filter medium such as activated carbon or ceramic balls, the filter medium is not affected by the water flow. Less rampage.

However, even if the filtration tank 5 is installed in the vertical direction, if the hot water is allowed to flow upward from below, the lighter granular filter medium will be violated by the water flow.

When the filter is installed in a horizontal or oblique direction, since the gravity and the direction of the molten metal flow do not coincide with each other, if the filter medium is filled with the granular filter medium in a state where there is even a little space, light granularity is obtained. The filter media will be ramped by the water flow.

For this reason, it is required that the filtration tank 5 is always installed in the vertical direction, and that the hot water flows from top to bottom. For this reason,
In order to make the apparatus compact and easy to maintain, it was not possible to design the filtration tank to be installed horizontally or diagonally.

The present invention solves the above-mentioned drawbacks of the prior art, and can be installed in any of vertical, horizontal and diagonal directions irrespective of the weight of the granular filter material filling the filtration tank 5, and the hot water is removed. It is an object of the present invention to provide a device which is freely installed so that there is no restriction on the flowing direction and the device is compact and easy to maintain.

[0016]

In other words, the filtration tank is provided with
The granular filter medium is pressed and fixed with an elastic member and filled, and the filtration tank 5 is installed in any direction of vertical, horizontal and diagonal, in which direction the hot water flows, and the amount of the granular filter medium to be filled is Even if changed, the light granular filter media was prevented from rampaging by the water flow.

Further, an elastic member for fixing the granular filter medium is formed of a spring material or a rubber material, and the granular filter medium is simply and firmly pressed and fixed, and the filter tank 5 can be oriented in any of vertical, horizontal and oblique directions. Even if the hot water is flowed in any direction and the amount of the filled granular filter medium changes, the light granular filter medium is prevented from being violated by the water flow due to the pressing action.

And a side sectional view of the filtration tank 5 of FIG.

In FIG. 1, reference numeral 14 denotes a tank case having a hot water inlet 15 and a hot water outlet 16, and reference numeral 17 denotes a granular filter medium. As the granular filter medium 14, any granular filter medium including light activated carbon, ceramic balls and the like can be used. Numerals 18 and 19 are a lid and a bottom net plate for preventing the granular filter medium 17 from leaking out of the hot water outlets 15 and 16.

Reference numeral 20 denotes an elastic member, which is made of an elastic material such as a spring or sponge rubber, and firmly fixes the granular filter medium 17 filled in the tank case 14 by utilizing elastic force.

In order to form the filtration tank 5, the tank case 14 is set up, the bottom mesh plate 18 is fitted to the bottom, a predetermined amount of the granular filter medium 17 is put in, and the lid mesh plate 17 is placed on the filled granular filter medium 17. Finally, the lid 19 is placed while the granular filter medium 17 is pressed toward the bottom net plate 18 by the elastic member 20 via the net plate 19 for lid.

Then, as shown in FIG. 1, the filter tank 5 is filled with the particulate filter medium 17 in a firmly fixed state that does not move at all even if it is turned sideways.

Since the granular filter medium 17 is pressed and fixed by the elastic member 20, even if the amount of the granular filter medium 17 to be filled is reduced as shown in FIG. Can be firmly pressed and fixed.

If the granular filter medium 17 is an elastic member and is firmly pressed and filled with no gap between the bottom and lid netting plates 18 and 19, the filter medium shown in FIGS. Even if the hot water flows strongly in the direction of arrow A from the hot water inlet 15 to the outlet 16 as described above, the light granular filter medium 17 may be violated by the water flow regardless of the installation direction of the filtration tank 5 or the direction of the hot water flow. There is nothing.

Therefore, even if the filtration tank 5 is installed in the vertical direction and hot water flows from bottom to top, or if it is installed horizontally or diagonally, the problem caused by the filter medium going out does not occur, and the design of the apparatus is free. become.
