ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to warm/cold double-circulation water filter system and swimming pool arrangement and more particularly to a pipe controlling means.
BACKGROUND OF THE INVENTION
For background, reference is made to U.S. patent application Ser. No. 09/752,428, now U.S. Pat. No. 6,425,999 which describes a double-circulation water filter system and swimming pool arrangement. The swimming pool is separated into two pools for enabling warm/cold water to be respectively circulated through the pools of the swimming pol via a divided water filter unit and enables warm/cold water to be selectively circulated through the two pools of the swimming pool. The water pipe system
4
is between a swimming pool
1
and a double-circulation water filter system
3
. (refer to
FIG. 4
of originally filed application). The swimming pool
1
is separated into two separated pools, a first pool
12
and a second pool
14
. Each of the pools
12
and
14
has a water outlet
122
or
142
, and a plurality of water inlets
124
or
144
. The water pipe system
4
connects the water inlets
122
and
142
of the pools
12
and
14
to the water inlets
124
and
144
through the double-circulation water filter system
3
. Electromagnetic valves A, B, C, D, E and F are installed in the water pipe system
4
, and are adapted to control the direction of water flow. The inconvenient control and management of the valves that are dispersed along the water pipe system
4
, raise an issue to be resolved.
SUMMARY OF THE INVENTION
It is an objective of the invention to provide a warm/cold double-circulation water filter system and swimming pool arrangement which concentrated on the valves in order to convenient management and control.
It is another objective of the invention to provide a warm/cold double-circulation water filter system and swimming pool arrangement which reduce the amount of the valves.
It is another objective of the invention to provide a warm/cold double-circulation water filter system and swimming pool arrangement which supply a multiform elevated temperature manner.
