Toilet flush water colorizer

Abstract

.[.A toilet flush water colorizer comprises a container adapted for receiving therein a flush water-coloring block and having at least one entry opening for admitting flush water thereinto, and outlet means for the discharge of colored flush water from the container, which colorizer further comprises suspending means for suspending the container at the inside of a toilet bowl, a diluting chamber in the interior of the container adapted for collecting drops of color concentrate dripping off a block after each flushing, the outlet means being located in the bottom of the diluting chamber..]..Iadd.A toilet flush colorizer container is suspendable in a toilet bowl. The upper part of the container admits flush water and, after passing over a colorizer block, colored water collects in a diluting chamber. The colored water is transferred to the toilet bowl by means of a siphon in the bottom of the diluting chamber..Iaddend.

We claim: 
     
       1. A toilet flush water colorizer comprising a container adapted for receiving therein a flush water-coloring block and having at least one entry opening .Iadd.in the upper part of said container .Iaddend.for admitting .Iadd.said .Iaddend.flush water thereinto and outlet means for the discharge of colored flush water from said container, said colorizer further comprising means for suspending said container at the inside of a toilet bowl, a diluting chamber in the lower part of the interior of said container and adapted for collecting drops of color concentrate dripping off a block after each flushing; supporting means in said container across the upper end of said diluting chamber and adapted for supporting a flush water-coloring block in the upper part of said container above said diluting chamber, said supporting means having at least one opening for permitting flush water to pass from the upper part of said container into said diluting chamber, said container having a bottom and side walls, said side walls being closed up to the upper end of said diluting chamber, and wherein said outlet means are located in the bottom of said container in communication with said diluting chamber and comprise siphoning means having a siphon passage the apex of which passage is below said upper end of said diluting chamber and below the level of said supporting means, said siphoning means being adapted for siphoning off flush water from said diluting chamber down to a minimum sump level. 
     
     
       2. The toilet flush water colorizer of claim 1, wherein said supporting means have a plurality of openings which are narrow enough to prevent larger pieces of a coloring block being eroded by flush water from dropping into said diluting chamber. 
     
     
       3. The toilet flush water colorizer of claim 1, wherein said supporting means comprise projections from the inner side wall of said container into the interior of the latter. 
     
     
       4. The toilet flush water colorizer of claim 1, wherein said supporting means comprise a grip or perforated plate adapted for supporting a coloring block. 
     
     
       5. The toilet flush water colorizer of claim 1, wherein said siphoning means comprise a suction tube in the lower part of said diluting chamber for suctioning off colored flush water under the hydrostatic pressure thereof in said diluting chamber. 
     
     
       6. The toilet flush water colorizer of claim 5, wherein said suction tube is sealingly inserted in the bottom of said diluting chamber and has its upper end curved whereby its upper opening is near the bottom of said diluting chamber. 
     
     
       7. The toilet flush water colorizer of claim 5, wherein said suction tube is sealingly inserted upright in the bottom of said diluting chamber, having its upper opening near the upper end of said diluting chamber and its lower opening in or underneath said bottom, and wherein said siphoning means further comprise a cover member mounted on said bottom and having a closed upper part inside which the upper end of said suction tube opens, said cover member further having ports near or at the bottom of said diluting chamber for the passage of colored flush water from the latter chamber into the interior of said cover member and into said suction tube. .Iadd. 
     
     
       8.  A toilet flush water colorizer for coloring of flush water flowing from the cistern of a toilet to the toilet bowl and descending on the inner sidewall of the toilet bowl, when said toilet is flushed, said colorizer comprising:   a container adapted for receiving a flush-water coloring block in an upper part thereof and having, exclusively in said upper container part, at least one entry opening in the top of said container adapted for having said flush water pass therethrough from said cistern into said container upper part, during the time when said toilet is flushed;   suspending means for suspending said container at the upper region of the inner wall of the toilet bowl,   said container comprising a diluting chamber having a closed sidewall and being disposed below said upper container part,   supporting means adapted for supporting said coloring block and being located at the upper end of said diluting chamber above the highest level maintained by the flush water therein after each flushing until the next-following flushing;   said supporting means comprising at least one passage, through which only, at every flushing, flush water can flow from said entry opening and after having had contact with said coloring block in said upper container part, downward into said diluting chamber; and   siphoning means comprising a siphon passage having its apex located below said supporting means and below the upper end of said diluting chamber, and adapted for withdrawing colored flush water from said diluting chamber and discharging it through the bottom zone thereof into said toilet bowl..Iaddend.
