Abstract: A circuit device for a steam engine having a power unit is electrically connected to a positive electrode and a negative electrode of the power unit includes a switching unit having a positive voltage contact set and a negative voltage contact set and is switchable between a first mode, in which the power unit provides electricity to first contacts of the positive and negative voltage contact sets, and a second mode, in which the power unit provides electricity to second contacts of the positive and negative voltage contact sets, a heater module having an input end connected to first and second contacts of the positive voltage contact set and an output end thereof connected to the first contact of the negative voltage contact set, and a voltage step-down unit connected in series to the output end of the heater module and the second contact of the negative voltage contact set.

Abstract: An electric steam iron includes a steam generator with an output port, a switching device formed of a body and a movable member. The body has an inlet in air communication with the output port, a first outlet, a second outlet, a first passage in air communication with the inlet and the first outlet, and a second passage in air communication with the inlet and the second outlet. The movable member is disposed in the intersection between the first passage and the second passage and movable between a first position where steam goes out of the first outlet and a second position where steam goes out of the second passage. A cleaning device has a connector for connection to the body of the switching device to move the movable member from the first position to the second position and a nozzle connected to the connector for steam output.

Abstract: A steam iron includes a housing, a water tank and a boiler mounted in the housing, a water supply pipe for guiding water from the water tank to the boiler for boiling, a relief pipe connected between the boiler and the water tank for guiding steam from the boiler to the water tank when an internal pressure of the boiler is excessively high, a valve flap-operated one-way check valve mounted in the water supply pipe to let water pass from the water tank to the boiler and stop steam from pass through the water supply pipe to the water tank, and a piston-operated relief valve mounted in the relief pipe for enabling steam to pass to the water tank when the internal pressure of the boiler is excessively high.

Abstract: A safety structure of a steam ironing machine is formed of a main body, a boiler disposed in the main body for generating steam, and a water tank set disposed in the main body and formed of a water storage tank and a water level safety device for activating and deactivating the steam ironing machine on the basis of the water level in the water storage tank.

Abstract: A steam/ironing dual mode cleaning apparatus includes a housing defining a receiving chamber, a water tank unit mounted in the receiving chamber and adapted to hold water, a steam boiler mounted in the receiving chamber and adapted to boil water into steam, and a water pump unit mounted in the receiving chamber and horizontally aligned with the water tank unit and the steam boiler, the water pump unit having a water inlet fitting connected to a water output port of the water tank unit through a first water pipe, a water outlet fitting connected to a water input port of the steam boiler through a second water pipe, and a motor pump controlled to pump water from the water tank unit to the steam boiler for boiling.

Abstract: An improved pasta maker (20) is provided having an upper mixing chamber (130), lower extrusion chamber (132), and a communicating passageway (157) therebetween. The mixing chamber (130) is an open top vessel, and the extrusion chamber (132) presents an outlet (148) adapted to receive a pasta forming die (188). The pasta maker (20) also includes an apertured slide valve plate (26), a powered, rotatable mixing element (170) within the mixing chamber (130) for mixing of the ingredients therein, and a powered, axially rotatable auger (174) within the extrusion chamber (132) for conveying the ingredients towards and through the die (188).
