PURPOSE:To enhance the efficiency of suction and cleaning and to attain efficient cleaning by alternately using a solid detergent and a liq. detergent. CONSTITUTION:A suction pipe 3 is connected to one of overflows 4 and the others are blocked so as to prevent the inflow of air. A suction duct 6 is connected to a proper position of a drain duct 5, a dust remover 7 and a vacuum pump 8 are connected to the duct 6 and a dust discharge duct 10 is connected to the remover 7 through a dust discharge pump 11. At the time of cleaning, a solid detergent 1 and a liq. detergent 2 are alternately sucked from the suction pipe 3. The sucked detergent passes through the overflow 4, the drain duct 5 and the suction duct 6 to carry out cleaning and dust is removed with the dust remover 7. The dust and detergent are discharged into a sewer by the pump 11. Cleaning effect can be enhanced. |
