Field of the invention
[001]The present invention generally relates to toilet flush. More
particularly, the present invention relates to toilets having two flush
modalities, a full flush operation for solid waste and a partial flush
operation for liquid waste.
Background
[002]A gravity flush system is the oldest and simplest form of flushing
mechanism that uses the gravitational power to flush the waste. This
particular style of toilet flushing system uses the water weight, along with
gravity, to generate flushing pressure. The pressure forces everything
from the tank into the vessel and through the S-shaped trap way. A
siphoning action completes the flush. This flushing system is quieter and
requires less maintenance than any other type of flushing system. But at
the same time a gravity fed flushing system consumes a lot of water.
[003] With changing times and a need for attention to environmental and
water conservation issues, less water consuming flushing systems have
been invented, which are efficient and convenient. A dual flush system is
a relatively new concept that allows the user a choice of limiting the flow of
water. The dual flushing system has two separate flushing buttons that
are marked with a half tank and a full tank sign. This allows the consumer
to choose a lesser flow of water for liquid wastes and a full tank water flow
for solid wastes.
[004] Currently several types of dual water quantity toilet flushing devices
are available, but only as new toilet installations with completely new
internal mechanisms or by performing a complete rebuild of the internal
mechanisms in an existing type of standard or regular toilet either of which
can be expensive to the average homeowner. It is obvious that a simple
and easy to install and operate mechanism is needed at a low cost to
provide the necessary incentives to aid in conserving our limited supply of
water.
[005] The toilet flushing is very important necessary and most regular part
of day to day life of human being. During the flushing, generally the hands
are used. When hands came in contact with the flush lever or button the
transfer of bacteria takes place and that creates the hygiene problem.
[006] In light of the aforesaid discussion, there is a need for a toilet flushing
system which employs full flush for solid waste and partial flush for liquid
waste and which could be installed with the existing toilet. Further there is
a need for a toilet flushing system which eliminates the hygienic problem.
Objects of the Invention
[007]An object of the present invention is to provide a dual flush toilet
which employs full flush for solid waste and partial flush for liquid waste.
[008]Another object of the present invention is production of a dual flush
toilet which could be installed with the existing toilet.
[009] Still another object of the present invention is to provide dual flush
toilet which is operated by foot for eliminating the hygienic problem.
[0010] Still further object of the present invention is to come up with a
cost effective solutions for dual flush toilet.
