Abstract
An apparatus and a method for conserving the volume of water consumed during the flushing of waste deposited in the bowl of a toilet. A secondary water reservoir is mounted externally on the primary water reservoir of a conventional toilet. The primary water reservoir holds a first body of water whose volume is greater than a second body of water held by the secondary water reservoir. The first body of water may be discharged from the primary water reservoir directly into the bowl. Alternatively, the second body of water may be discharged from said second water reservoir into a water feed member which is mounted externally on the rim of the bowl and which directs said second body of water into said bowl along its perimeter in a slight downwardly direction.
Claims26
A water conservation unit for a toilet having a primary water reservoir with a predetermined volume, a bowl with a rim defining a perimeter and a water supply, comprising:
- (a) a secondary water reservoir having an input orifice and a discharge orifice, said secondary water reservoir having a volume less than the volume of said primary water reservoir and adapted to be mounted externally of said primary reservoir;
- (b) input means for introducing and controlling the flow of water into the input orifice of said secondary water reservoir;
- (c) a water feed member having an inlet orifice, an outlet orifice, and a continuous passage therethrough connecting said inlet and outlet orifices, said water feed member comprising a substantially flat portion intermediate said inlet and outlet orifices and a depending leg portion including said outlet orifice therein said water feed member adapted to be attached to said bowl rim in such a manner that said outlet orifice is contained within and directed along the perimeter of said bowl;
- (d) means for coupling the discharge orifice of said secondary water reservoir to the inlet orifice of said water feed member;
- and
- (e) discharge means for opening and closing the discharge orifice of said secondary water reservoir.
A water saving toilet comprising:
- (a) a primary water reservoir containing a first body of water having a predetermined volume;
- (b) a bowl for depositing waste material, said bowl having a rim defining a perimeter;
- (c) first input means for introducing water into said primary water reservoir;
- (d) first discharge means for discharging said first body of water into said bowl;
- (e) a secondary water reservoir containing a second body of water, wherein said second body of water has a volume less than the volume of said first body of water;
- (f) mounting means for mounting said secondary water reservoir externally to said first water reservoir;
- (g) second input means for introducing and controlling water into said secondary water reservoir;
- (h) second discharge means for discharging said second body of water from said second water reservoir;
- (i) a water feed member having an inlet orifice, an outlet orifice, and a continuous passage therethrough connecting said inlet and outlet orifices, said water feed member comprising a substantially flat portion intermediate said inlet and outlet orifices and a depending leg portion including said outlet orifice therein, said water feed member attached to said bowl wherein said outlet orifice is contained within and directed along the perimeter of said bowl and in a generally downwardly direction;
- and
- (j) connecting means for coupling said secondary water reservoir to the inlet orifice of said water feed member.
A method for conserving the amount of water consumed in flushing waste from a toilet having a primary water reservoir for holding a first body of water having a predetermined volume and a bowl with a rim defining a perimeter, comprising the steps of:
- (a) externally mounting a secondary water reservoir from the primary water reservoir, wherein the secondary water reservoir holds a second body of water whose volume is less than the volume of the first body of water;
- (b) fluidly connecting said secondary water reservoir to a water supply and filling said secondary water reservoir to a predetermined level;
- (c) mounting a water feed member comprising a substantially flat portion and a depending leg portion including an outlet orifice on the rim of said toilet bowl and fluidly connecting said secondary water reservoir to said water feed member;
- (d) actuating said secondary water reservoir and discharging the second body of water from said secondary water reservoir into said water feed member, said water feed member outlet orifice directing said discharged water into said toilet bowl along said perimeter and in a generally downwardly direction.
