Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to swimming pools and, more
specifically, to a double-circulation water filter system and
swimming pool arrangement, which enables warm and/or cold water to
circulate through two separated pools of the swimming pool via a
double-circulation water filter system.
[0002] Regular swimming pools are commonly designed for circulation
of cold water through a single-circulation water filter system.
FIG. 1 shows the arrangement of a swimming pool and
single-circulation water filter system according to the prior art.
A swimming pool of this design is suitable for use in summer season
only. There are also known swimming pools for circulation of warm
water. However, some people would not like to swim in warm water
even in winter season. According to conventional designs, it is
expensive to build a swimming pool for cold water and a swimming
pool for warm water. Further, building two swimming pools requires
a big land area.
SUMMARY OF THE INVENTION
[0003] The present invention has been accomplished to provide a
warm/cold double-circulation water filter system and swimming pool
arrangement, which separates the swimming pool into two pools for
enabling warm/cold water to be respectively circulated through the
pools of the swimming pool via a respective water filter unit. It
is another object of the present invention to provide a warm/cold
double-circulation water filter system and swimming pool
arrangement, which enables warm/cold water to be selectively
circulate through the two pools of the swimming pool. The warm/cold
double-circulation water filter system and swimming pool
arrangement of the present invention comprises a swimming pool
separated into two pools, each pool having a water outlet and a
plurality of water inlets, a double-circulation water filter system
adapted to treat water circulated through the pools of the swimming
pool, the double-circulation water filter system including a first
filter unit, a second filter unit, and a heater, and a water pipe
system adapted to deliver water from the water outlet of each of
the pools of the swimming pool to the water inlets of each of the
pools of the swimming pool through the double-circulation water
filter system, the water pipe system having valve means selectively
controlled to let water pass from the first filter unit and second
filter unit of the double-circulation water filter system to the
water inlets of the pools of the swimming pool via the heater.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0008] Referring to FIG. 2, a swimming pool 1 comprises a partition
wall 20. The partition wall 20 is comprised of a plurality of round
pots 22 and partition boards 24, and separates the swimming pool 1
into two separated pools, namely, the first pool 12 and the second
pool 14. The pools 12 and 14 each have a water outlet 122 or 142,
and a plurality of water inlets 124 or 144. The round rods 22 are
fixedly perpendicularly fastened to the bottom wall of the swimming
pool 1, and aligned in a line between the two endwalls of the
swimming pool 1 (i.e., in parallel to the two sidewalls of the
swimming pool 1). Each round post 22 has two longitudinal coupling
grooves 222 disposed at two sides. The partition boards 20 are
respectively coupled to the coupling grooves 222 of the round posts
22. The round posts 22 are preferably mad of stainless steel. The
partition boards 24 are made of material of high tensile strength.
The partition wall 20 prevents circulation of water between the
pools 12 and 14.
[0009] Referring to FIGS. 3 and 4 and FIG. 2 again, the present
invention further comprises a double-circulation water filter
system 3, and a water pipe system 4. The double-circulation water
filter system 3 comprises two filter units, namely, the first
filter unit 30 and the second filter unit 40, and a heater 50. The
filter units 30 and 40 each comprise a filter tank 32 or 42, a
chlorinator 34 or 44, a chemical dispenser 36 or 46, and a hair
remover 38 or 48, and are controlled to filter and sterilize water
passing through. The water pipe system 4 connects the water outlets
122 and 142 of the pools 12 and 14 to the water inlets 124 and 144
through the double-circulation water filter system 3. Water
outputted from the water outlet 122 or 142 of the pool 12 or 14 is
delivered by the water pipe system 4 to the double-circulation
water filter system 3 for treatment, and well-treated water is then
delivered by the water pipe system 4 to the pool 12 or 14 through
the respective water inlets 124 or 144. Electromagnetic valves A,
B, C, D, E and F are installed in the water pipe system 4, and
adapted to control the flowing direction of water.
[0010] Referring to FIG. 4 again, the pools 12 and 14 are separated
from each other for circulation of hot water and cold water
respectively. The operation procedure of the present invention is
outlined hereinafter:
[0011] 1. When the second pool 14 is set for warm water, the first
pool 12 is set for cold water, the electromagnetic valves A, D and
E are closed, and the electromagnetic valves B, C and F are opened.
At this time, warm water passes out of the water outlet 142 of the
second pool 14 through the water pipe system 4 into the first
filter unit 30 where warm water is treated in proper order through
the hair remover 38, the filter tank 32, the chlorinator 34 and the
chemical dispenser 36, and then passes out of the chemical
dispenser 36 of the first filter unit 30 through the
electromagnetic valve B to the heater 50 for heating, and then
passes from the heater 50 through the electromagnetic valve C to
the second pool 14 again. At the same time, cold water passes out
of the water outlet 122 of the first pool 12 through the water pipe
system 4 into the second filter unit 40 where cold water is treated
in proper order through the hair remover 48, the filter tank 42,
the chlorinator 34 and the chemical dispenser 46, and then passes
from the chemical dispenser 46 of the second filter unit 40 through
the electromagnetic valve F to the first pool 12 again.
[0012] 2. When the second pool 14 is set for cold water, the first
pool 12 is set for warm water, the electromagnetic valves A, D and
E are opened, and the electromagnetic valves B, C and F are closed.
At this time, warm water passes out of the water outlet 122 of the
first pool 12 through the water pipe system 4 into the second
filter unit 40 where warm water is treated in proper order through
the hair remover 48, the filter tank 42, the chlorinator 44 and the
chemical dispenser 46, and then passes out of the chemical
dispenser 46 of the second filter unit 30 through the
electromagnetic valve D to the heater 50 for heating, and then
passes from the heater 50 through the electromagnetic valve E to
the first pool 12 again. At the same time, cold water passes out of
the water outlet 142 of the second pool 14 through the water pipe
system 4 into the first filter unit 30 where cold water is treated
in proper order through the hair remover 38, the filter tank 32,
the chlorinator 34 and the chemical dispenser 36, and then passes
from the chemical dispenser 36 of the first filter unit 30 through
the electromagnetic valve A to the second pool 14 again.
[0013] 3. When both pools 12 and 14 are set for cold water in
Summer, the electromagnetic valves B, C, D and E are closed, and
the electromagnetic valves A and F are opened. In this case, water
is prohibited from passing through the heater 5. On the contrary,
when both pools 12 and 14 are set for warm water in winter, the
electromagnetic valves A and F are closed, and the electromagnetic
valves B, C, D and E are opened. In this case, water from the first
pool 12 as well as w the second pool 14 is allowed to pass through
the heater 50 for heating.
[0014] As indicated above, the warm/cold double-circulation water
filter system and swimming pool arrangement of the present
invention comprises a swimming pool, which is separated by a
partition wall into two separated pools, a double-circulation water
filter system, which has two filter units adapted to filter water
from the two pools respectively, a heater adapted to heat water
passing through, and a water pipe system with valve means adapted
to control circulation of water from each pool through the
double-circulation water filter system only, or selectively through
the double-circulation water filter system and the heater.
[0015] It is to be understood that the drawings are designed for
purposes of illustration only, and are not intended for use as a
definition of the limits and scope of the invention disclosed.
