Floor scrubber cleaning system using coolant for heating a cleaning solution

Abstract

A floor scrubber cleaning system includes a combustion engine powered floor scrubber using at least one rotating scrubbing brush/pad. A tank or reservoir is used for supplying a cleaning solution to the scrubbing brush/pad for cleaning a floor. A heat exchanger uses coolant from the combustion engine to heat the cleaning solution where it is dispensed directly onto the floor.

We claim: 
     
         1 . A floor scrubber cleaning system comprising;
 a combustion engine powered floor scrubber using at least one rotating scrubbing brush;   at least one tank for supplying a cleaning solution for cleaning a floor; and   a heat exchanger for heating the cleaning solution flowing from the at least one tank using engine coolant from the combustion engine.   
     
     
         2 . A floor scrubber cleaning system as in  claim 1 , wherein the scrubbing brush is a disk moving in a cylindrical orbital motion. 
     
     
         3 . A floor scrubber cleaning system as in  claim 2 , wherein the scrubbing brush rotates in a manner so to parallel with a floor surface. 
     
     
         4 . A floor scrubber system as in  claim 1 , wherein the cleaning solution moving through the heat exchanger is applied directly to the floor. 
     
     
         5 . A floor scrubber cleaning system as in  claim 1 , wherein the at least one tank uses gravity feed to supply the cleaning solution to the heat exchanger. 
     
     
         6 . A floor scrubber cleaning system as in  claim 1 , wherein the heat exchanger is a brazed plate heat exchanger. 
     
     
         7 . A floor scrubber cleaning system comprising;
 a powered floor scrubber using a combustion engine;   at least one rotating cleaning implement for scrubbing a floor;   at least one tank for supplying a cleaning solution to the floor; and   a heat exchanger for heating the cleaning solution by flowing engine coolant used to cool the combustion engine in proximity to the cleaning solution from the least one tank such that heat is transferred from the engine coolant to the cleaning solution before application to the floor.   
     
     
         8 . A floor scrubber cleaning system as in  claim 7 , wherein the floor scrubber scrubs dirt by moving the cleaning implement in a circular motion across a floor. 
     
     
         9 . A floor scrubber cleaning system as in  claim 7 , wherein the cleaning implement rotates in a manner so be parallel with a floor surface. 
     
     
         10 . A floor scrubber cleaning system as in  claim 7 , wherein the cleaning implement is either a scrubbing brush or cleaning pad. 
     
     
         11 . A floor scrubber system as in  claim 7 , wherein the temperature of the cleaning solution is measured before being applied to a floor. 
     
     
         12 . A floor scrubber cleaning system as in  claim 7 , wherein the at least one tank uses a gravity feed to supply the cleaning solution to the heat exchanger. 
     
     
         13 . A floor scrubber cleaning system as in  claim 7 , wherein the heat exchanger is a brazed plate heat exchanger. 
     
     
         14 . A floor scrubber cleaning system comprising;
 a combustion engine powered floor scrubber using a radiator holding liquid coolant for use in cooling the engine;   at least one rotating scrubbing brush for removing dirt from a floor;   at least one tank holding a cleaning solution sprayed onto a floor;   a pump for directing the cleaning solution to the at least one rotating scrubbing brush; and   a heat exchanger for heating the cleaning solution by directing the cleaning solution from the at least one tank though a heat exchanger where heat for the engine coolant is transferred to the cleaning solution before being applied to the floor.   
     
     
         15 . A floor scrubber cleaning system as in  claim 14 , wherein the scrubbing brush moves in a cylindrical orbital motion. 
     
     
         16 . A floor scrubber cleaning system as in  claim 15 , wherein the scrubbing brush rotates in a manner so to be parallel with a floor surface. 
     
     
         17 . A floor scrubber system as in  claim 14 , wherein the cleaning solution moving through the heat exchanger is applied directly to the floor. 
     
     
         18 . A floor scrubber cleaning system as in  claim 14 , wherein the at least one tank uses a gravity feed to supply the cleaning solution to the heat exchanger. 
     
     
         19 . A floor scrubber cleaning system as in  claim 14 , wherein the heat exchanger is a brazed plate heat exchanger.
