Water filter description
BACKGROUND OF THE INVENTION
The present invention relates to a water filter tank, and more
particularly to a combination water filter tank, which guides water
to flow up and down, enabling solid matter to settle to the bottom.
A variety of water filters have been disclosed, and have appeared
on the market. These water filters commonly use a filter element
to remove solid matter from water. However, because the filter element
has a limited service life, it must be frequently replaced. If the
filter element is overused, water cannot be well purified.
SUMMARY OF THE INVENTION
It is the main object of the present invention to provide a combination
water filter tank, which enables solid matter to settle to the bottom
of the water passing through without the use of any filter element.
According to one aspect of the present invention, the combination
water filter tank comprises a rectangular housing, three transverse
partition boards disposed in the housing and defining a first sedimentation
chamber, a second sedimentation chamber, a third sedimentation chamber
and a fourth sedimentation chamber, a water inlet for guiding water
from an external water source into the first sedimentation chamber,
a plurality of first longitudinal partition boards of different
heights respectively disposed in the first sedimentation chamber,
three L-shaped water guide boards respectively suspended in the
second sedimentation chamber, third sedimentation chamber and fourth
sedimentation chamber, a plurality of second longitudinal partition
boards respectively disposed in the second sedimentation chamber,
third sedimentation chamber and fourth sedimentation chamber on
the middle at an elevation below the L-shaped water guide boards,
and a water outlet for guiding water out of the fourth sedimentation
chamber. According to another aspect of the present invention, the
sedimentation chambers each comprise a bottom wall, and at least
one drain hole on the bottom wall for guiding sediment out of the
housing, wherein the bottom wall is curved inwards toward the at
least one drain hole for enabling sediment to be accumulated at
the at least one drain hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2 a combination water filter tank is
shown comprising a rectangular housing 100. Three transverse partition
boards 1 are disposed in the housing 100 defining four sedimentation
chambers 2 3 4 and 5. The transverse partition boards 1 each comprise
a water guide hole 11. The first sedimentation chamber 2 comprises
a water inlet 21 at one side, and a plurality of longitudinal partition
boards 22 of different heights. The second, third and fourth sedimentation
chambers 3 4 and 5 each comprise a longitudinal partition board
32 42 or 52 disposed on the middle, and a substantially L-shaped
water guide board 31 41 or 51 suspended at one at an elevation
higher than the topmost edge of the longitudinal partition board
32 42 or 52. The sedimentation chambers 2 3 4 and 5 each further
comprise a plurality of drain holes 23 at the bottom side. The bottom
wall of each sedimentation chamber 2 3 4 or 5 curves inwards toward
the respective drain holes 23. When water is guided from a water
source through the water inlet 21 into the combination water filter
tank, it flows over the longitudinal partition boards 22 in the
first sedimentation chamber 2 and then flows in proper order through
the second, third and fourth sedimentation chambers 3 4 and 5
along the respective L-shaped water guide boards 31 41 and 51 via
the respective water guide holes 11. Because of the buffering of
the partition boards 22 32 42 and 52 and the L-shaped water guide
board 31 41 and 51 water flows slowly and smoothly through the
sedimentation chambers 2 3 4 and 5 enabling solid matter to settle
to the bottom. Filtered pure water flows out of the fourth sedimentation
chamber 5 through a water outlet 54.
Because the bottom wall of each sedimentation chamber 2 3 4 or
5 curves inwards toward the respective drain holes 23 sediment
is gathered at the drain holes 23 33 43 and 53. When the drain
holes 23 33 43 and 53 are opened a certain length of time after
filtration, sediment is guided out of the combination water filter
tank.
While only one embodiment of the present invention has been shown
and described, it will be understood that various modifications
and changes could be made thereunto without departing from the spirit
and scope of the invention disclosed. |
