JPS55123930A - Disposal device for drain of window type air conditioner - Google Patents

Abstract

PURPOSE:To utilize drain housed in a drain receiving pan effectively, and to eliminate the need for a drain hose, by a mechanism wherein the drain is sprinkled to a condenser by means of a double centrifugal pump while the residue is made collide with an eliminator and atomized and discharged. CONSTITUTION:Drain d housed in a drain receiving pan 3 is sucked up from an outer suction port 11 of a double centrifugal pump 7 driven by means of a motor 6, is sprinkled to a condenser 4 from an outer discharge port 15 through a low water- level drain suck-up passage 13 in a granular shape and is evaporated, and promotes the radiation of the condenser. When a water-level of the drain d is high and there is drain d which cannot be utilized by means of the condenser 4, the drain is sucked up from an inner suction port 12 of the double centrifugal pump 7, blown against an eliminator 8 from an inner discharge port 16 through a high water-level drain suck-up passage 14 and atomized, and discharged by means of a blast fan 9. Thus, the drain d is effectively disposed by means of a drain disposal device 5 in response to the quantity of formation, and a drain hose can be removed.
