     THE DESCRIPTION OF PREFERRED EMBODIMENT 
     An apparatus for supplying detergent to the water where every portion of the detergent solution dispensed from the vessel is compensated for by portion of water is shown in FIGS. 1 to  6 . 
     The apparatus ( 10 ) consists of a toilet water tank ( 11 ), a valve ( 12 ), an overflow pipe ( 14 ), a vessel ( 16 ), a water supplying and portioning mechanism ( 20 ). 
     The water supplying and portioning mechanism ( 20 ) consists of lever ( 24 ), a first tube ( 26 ), a second tube ( 28 ), a third tube ( 30 ), a 3 way connector ( 32 ), a detergent tube ( 42 ), a slide ( 44 ), a slide guide ( 46 ) and a float ( 48 ). 
     The valve ( 12 ) has an outlet ( 50 ). The first tube ( 26 ) is connected with the outlet ( 50 ) and the 3 way connector ( 32 ). The second tube ( 28 ) is connected to the 3 way connector ( 32 ) on of one its end and is open on the other end. This end is located into overflow pipe ( 14 ) and supply water to the tank ( 11 ) after flush. The third tube ( 30 ) is connected to the 3 way connector ( 32 ) on one end and is open on its other end. The inside diameter of the third tube ( 30 ) is much smaller than the inside diameter of the first tube ( 26 ) and second tube ( 28 ). So the water stream coming from the valve ( 12 ) through tube ( 26 ) is divided on large stream coming into the second tube ( 28 ) and into small stream coming into the third tube ( 30 ). 
     The vessel ( 16 ) is mounted in a water tank ( 11 ) and has an outlet ( 33 ) and a notch ( 53 ). A detergent solution ( 34 ) and a detergent tablet ( 36 ) are located into the vessel ( 16 ). 
     The detergent tube ( 42 ) consist of a first rigid part ( 64 ), then a median bendable part ( 66 ) and a second rigid part ( 68 ). It is connected to the outlet ( 33 ) by the first rigid part ( 64 ) and it is open on the second rigid part ( 68 ). 
     The slide ( 44 ) can freely slide along a slide guide ( 46 ). The float ( 48 ) is mounted on the lower end of the slide ( 44 ). The upper end of the slide ( 44 ) has a slide axle hole ( 72 ), and a slot ( 74 ). 
     A detergent tube guide ( 70 ) is mounted on the upper end of the slide ( 44 ) and it has a detergent tube hole ( 47 ) 
     The lever ( 24 ) has a water tube hole ( 76 ), a lever axle hole ( 78 ) and a lever slot ( 80 ). A lever axle ( 82 ) is mounted on the wall ( 81 ) of the vessel ( 16 ) and located in lever axle hole ( 78 ). 
     The lever ( 24 ) can be rotated around the lever axle ( 82 ). A slide axle ( 84 ) is mounted into the slide axle holes ( 72 ) and located inside the lever slot ( 80 ). 
     The second rigid part ( 68 ) of the detergent tube ( 42 ) is located into the detergent tube hole ( 47 ) (See FIG.  3 ). An end ( 86 ) of the third tube ( 30 ) is mounted into the water tube hole ( 76 ). 
     The position of the lever ( 24 ), of the end ( 86 ) of the third tube ( 30 ) and the second rigid part ( 68 ) of the detergent tube ( 42 ) depends on the position of the slide ( 44 ). When the slide ( 44 ) is in the up position the second rigid part ( 68 ) is in up and the end ( 86 ) of the third tube ( 30 ) is in down position, so detergent solution is not pouring from the vessel ( 16 ) and the water from the third tube ( 30 ) is pouring lower of the notch ( 53 ) and entering the tank ( 11 ). When the slide ( 44 ) is in down position the second rigid part ( 68 ) is down and the end ( 86 ) of the third tube ( 30 ) is in up position, so detergent solution enters from the vessel ( 16 ) into tank ( 11 ) and the water from the third tube ( 30 ) is pouring through of the notch ( 53 ) into the vessel ( 16 ). It happened when water in the tank ( 11 ) is in the lowest level after flushing. 
     The portion of the water reaching the detergent solution in the vessel ( 16 ) is slightly larger that the portion of the detergent solution leaking from the detergent tube ( 42 ). This small portion of extra water (or detergent solution) will leak through the notch ( 53 ) in the tank ( 11 ). 
     An apparatus where the level of a detergent solution is controlled by detergent float is shown in FIG.  5 . 
     The apparatus ( 100 ) consists of a valve ( 112 ), an overflow pipe ( 114 ), a vessel ( 116 ), a water supplying mechanism ( 120 ) and a portioning mechanism ( 140 ) 
     The water supplying mechanism  120 ) consists of a solution float ( 122 ), a lever ( 124 ), a water tube guide ( 125 ), a first tube ( 126 ), a second tube ( 128 ), a third tube ( 130 ) and a 3 way connector ( 132 ). 
     The vessel ( 116 ) has a detergent tablets ( 134 ) and a detergent solution ( 136 ) 
     The portioning mechanism ( 140 ) consists of a detergent tube ( 142 ), a slide ( 144 ), a detergent tube guide ( 147 ) and a slide guide ( 146 ). 
     The valve ( 112 ) has an outlet ( 150 ). The first tube ( 126 ) is connected with the outlet ( 150 ) and the 3 way connector ( 132 ). The second tube ( 128 ) is connected to the 3 way connector ( 132 ) on one it&#39;s end and is open on it other end. This end is located into overflow pipe ( 114 ) and supplies water to the tank ( 111 ) after flush. The third tube ( 130 ) is connected to the 3 way connector ( 132 ) on one end and is open on its other end. The inside diameter of the third tube ( 130 ) is much smaller than inside diameter of the first tube ( 126 ) and second tube ( 128 ). So the water stream coming from the valve ( 112 ) through tube ( 126 ) is divided on large stream coming into the second tube ( 128 ) and into small stream coming into the third tube ( 130 ). The end of the third tube ( 130 ) is mounted into the hole ( 76 ) of the water tube guide ( 125 ). 
     The lever ( 124 ) is mounted on the wall ( 154 ) of the vessel ( 116 ) and can be rotated around the axes parallel to upper edge of the wall ( 154 ). The water tube guide ( 125 ) is mounted on the one end of the lever ( 124 ) The solution float ( 122 ) is mounted on the other end of the lever ( 124 ). The solution float ( 122 ) floats on the detergent solution ( 130 ) of the vessel ( 116 ). Position of the solution float ( 122 ), the lever ( 124 ) and the end of the third tube ( 130 ) depend on the level of solution ( 136 ) in the vessel ( 116 ). When the level of the solution ( 136 ) is high the water is coming during flushing from pipe-line through the valve ( 112 ) and exiting from the ends of the second tube ( 128 ) into overflow pipe ( 114 ) and from the end of the third tube ( 130 ) into the tank ( 111 ). When the level of the solution ( 136 ) is low, the end of the third tube ( 130 ) is in the higher position and pours water into the vessel ( 116 ) while flushing. Because the vessel ( 116 ) regularly contents a much more solid tablets of detergent than necessary for saturating the solution the concentration of the solution, is about the same until last of the tablets dissolves. 
     An apparatus for supplying detergent to the water tank where a portion of water is added to the detergent solution with each flush and forming the same portion of the solution to pour into the water tank is shown in FIG.  6 . 
     The apparatus ( 200 ) consists of a toilet water tank ( 211 ), a valve ( 212 ), an overflow pipe ( 214 ), a vessel ( 216 ), a water supplying and portioning mechanism ( 220 ). 
     The valve ( 212 ) has an outlet ( 250 ). The water supplying and portioning mechanism ( 220 ) consists of lever ( 224 ), a first tube ( 226 ), a second tube ( 228 ), a third tube ( 230 ), a 3 way connector ( 232 ), a slide ( 244 ), a slide guide ( 246 ) and a float ( 248 ). 
     The first tube ( 226 ) is connected with the outlet ( 250 ) and the 3 way connector ( 232 ). The second tube ( 228 ) is connected to the 3 way connector ( 232 ) on of one its end and is open on the other end. This end is located into overflow pipe ( 214 ) and supply water to the tank ( 211 ) after flush. The third tube ( 230 ) is connected to the 3 way connector ( 232 ) on one end and is open on its other end. The inside diameter of the third tube ( 230 ) is much smaller than the inside diameter of the first tube ( 226 ) and second tube ( 228 ). So the water stream coming from the valve ( 212 ) through tube ( 226 ) is divided on large stream coming into the second tube ( 228 ) and into small stream coming into the third tube ( 230 ). 
     The vessel ( 216 ) is mounted in a water tank ( 211 ) and has notches ( 253 ) and with the notch ( 255 ) as being a detergent delivery means. A detergent solution ( 234 ) and a detergent tablet ( 236 ) are located into the vessel ( 216 ). 
     The slide ( 244 ) can freely slide along a guide ( 246 ). The float ( 248 ) is mounted on the lower end of the slide ( 244 ). The upper end of the slide ( 244 ) has a slide axle hole ( 272 ). 
     The lever ( 224 ) has a water tube bole ( 276 ), a lever axle hole ( 278 ) and a lever slot ( 280 ). A lever axle ( 282 ) is mounted on the wall ( 281 ) of the vessel ( 216 ) and located in lever axle hole ( 278 ). 
     The lever ( 224 ) can be rotated around the lever axle ( 282 ). A slide axle ( 284 ) is mounted into the slide axle holes ( 272 ) and located inside the lever slot ( 280 ).
