Floor scrubber cleaning system 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. A tank or reservoir is sued for supplying a cleaning solution to the scrubbing brush for cleaning a floor. A heat exchanger uses hot exhaust gasses 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 hot exhaust gasses from the floor scrubber.   
     
     
         2 . A floor scrubber system as in  claim 1 , wherein the cleaning solution moving through the heat exchanger is applied directly to the floor. 
     
     
         3 . A floor scrubber heating system as in  claim 1 , further comprising:
 a muffler/catalytic converter positioned between an engine and heat exchanger.   
     
     
         4 . A floor scrubber cleaning system as in  claim 1 , further comprising:
 at least one delivery bar for dispending heated floor solution onto the floor.   
     
     
         5 . A floor scrubber cleaning system as in  claim 1 , wherein the at least one tank uses a 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 uses a plurality of interwoven tubes for heating the cleaning solution moving though the plurality of tubes. 
     
     
         7 . A floor scrubber cleaning system as in  claim 1 , wherein the plurality of interwoven tubes includes at least three tubes. 
     
     
         8 . A floor scrubber cleaning system as in  claim 1 , wherein the heat exchanger is enclosed in a non-air tight housing. 
     
     
         9 . A floor scrubber cleaning system for heating a cleaning solution comprising:
 a powered floor scrubber using at least one scrubbing brush;   at least one tank for supplying a cleaning solution;   a heat exchanger for heating the cleaning solution flowing from the at least one tank using hot exhaust gasses from the floor scrubber; and   wherein a heated cleaning solution is applied directly to the floor being cleaned adjacent to the at least one scrubbing brush.   
     
     
         10 . A floor scrubber cleaning system as in  claim 9 , wherein the floor scrubber is powered by a combustion engine. 
     
     
         11 . A floor scrubber cleaning system as in  claim 9 , further comprising:
 a muffler/catalytic converter positioned between the powered floor scrubber and heat exchanger.   
     
     
         12 . A floor scrubber cleaning system as in  claim 9 , further comprising:
 at least one delivery bar for dispending the heated floor solution onto the floor.   
     
     
         13 . A floor scrubber cleaning system as in  claim 9 , wherein the at least one tank uses a gravity feed to supply the cleaning solution to the heat exchanger. 
     
     
         14 . A floor scrubber cleaning system as in  claim 9 , wherein the heat exchanger uses at least three interwoven tubes for heating the cleaning solution moving though the plurality of tubes. 
     
     
         15 . A floor scrubber cleaning system as in  claim 9 , wherein the at least one scrubbing brush is rotated in a substantially circular motion to clean the floor. 
     
     
         16 . A floor scrubber cleaning system for heating a cleaning solution applied to a floor comprising:
 a combustion engine powered floor scrubber using at least one scrubbing brush that rotates in a circular motion to clean the floor;   at least one reservoir for supplying a water-based cleaning solution;   a muffler for quieting the exhaust gases from the combustion engine;   a heat exchanger having a plurality of coils positioned within a non-airtight housing for heating the cleaning solution flowing from the at least one reservoir using hot exhaust gasses from the floor scrubber; and   wherein a heated cleaning solution is applied directly to the floor.   
     
     
         17 . A floor scrubber cleaning system as in  claim 16 , further comprising:
 at least one delivery bar for dispensing the heated cleaning solution onto the floor.   
     
     
         18 . A floor scrubber cleaning system as in  claim 16 , wherein the at least one reservoir uses gravity to supply the cleaning solution to the heat exchanger. 
     
     
         19 . A floor scrubber cleaning system as in  claim 16 , wherein the plurality of coils include at least three interwoven tubes. 
     
     
         20 . A floor scrubber cleaning system as in  claim 16  further comprising a valve for controlling flow of cleaning solution from the at least one reservoir to the heat exchanger.
