STEAM IRONING MACHINE Russian patent published in 1998 - IPC

FIELD: fabric ironing equipment. SUBSTANCE: ironing press has upper movable and lower immovable members. Ironing machine may have open and closed position, in which movable upper member is spaced from immovable lower member or connected with it. Fabric is positioned between upper and lower members, the latter are connected to iron the fabric. Upper member has water inlet opening, electric member for heating upper member surface adjoining lower member, as well as for heating water delivered through inlet opening till it transforms into steam, and openings disposed in lower part of upper member and adapted for discharge of steam to fabric in the process of ironing. Water reservoir has water outlet opening. Pump has housing with inlet opening connected to reservoir outlet opening and outlet opening connected to water inlet opening, and piston reciprocating within housing. DC motor has drive shaft which rotates in one direction, when direct voltage of selected polarity is supplied to motor, and rotates in opposite direction upon reversal of polarity of voltage supplied to motor. Drive shaft is connected with piston for moving it lengthwise of pump housing in one selected direction to draw water from reservoir into pump housing, when drive shaft rotates in one selected direction, and for moving piston lengthwise of pump housing in opposite direction to urge water from pump housing into water inlet opening of upper member. Direct voltage of selected polarity is supplied to motor to draw water from reservoir into pump housing. Voltage polarity reversal causes replacement of water from pump housing to water inlet opening. EFFECT: increased efficiency by providing electronic control of ironing process and enhanced reliability in operation. 15 cl, 12 dwg
