Abstract
A pressure dehydration low-frequency washing machine with a simplified structure using a single motor and a driving mechanism, including an electromotive rotation shaft horizontally installed below a washing tub, a selective drive for driving an oscillating plate of the washing tub by selectively converting rotation force of the electromotive rotation shaft to a reciprocation force according to the rotation direction of the electromotive rotation shaft, an air-compressor for converting the rotation force of the electromotive rotation shaft to a reciprocation force and compressing air by means of a piston driven by the reciprocation force, a pressure-applying dehydrator for applying pressure and dehydrating the laundry in the washing tub by being expanded by compressed air from the air-compressor when the electromotive rotation shaft is rotated in a direction where the selective drive is not driven, and a controller for selectively transferring the compressed air in the air-compressor to the pressure-applying dehydrator.
