Abstract: A method for controlling the dehydrating operation of a drum type washing machine includes a pre-acceleration step for accelerating a drum to a predetermined control starting speed, and a main accelerating step for accelerating the drum from the control starting speed to a target speed along a linear locus having a preset acceleration slope. A deviation of the center of gravity of the laundry and a pre-spinning time period are reduced in the aforementioned control method.

Abstract: The present invention relates a washing machine having a floatage clutch for performing the conversion of a cleansing step and a dehydrating step. This floatage clutch can be actuated only by using floatage and gravity to be generated during the feeding/draining of water without a separate driving part. Accordingly, the construction of clutch part can be simplified, and consequently the cost of manufacturing of the washing machine can be reduced.

Abstract: A drawer-type washing machine and process of washing laundry using the washing machine is disclosed. The washing machine has a housing opened at its front to form a cavity. A cabinet, opened at its top, is received in the cavity of the housing such that the cabinet is movable forward or backward relative to the housing. A washing tub unit, consisting of an outer tub and an inner tub, is set within the cabinet. This washing tub unit contains washing water therein, and carries out both a washing operation and a spin-drying operation for laundry contained therein. A drive unit is installed at a position under the outer tub of the washing tub unit, and rotates the inner tub of the washing tub unit. A suspension unit supports the washing tub unit within the cabinet while performing a damping function of attenuating operational vibrations of the washing tub unit.

Abstract: A dishwasher includes an interior tub and a wash pump for pumping wash liquid to wash dishes located in the interior tub. A pump motor for driving the wash pump is regulated by a control unit that adjusts a spraying pressure of wash liquid. The method for operating a dishwasher includes sensing the degree to which wash liquid is soiled and regulating the speed of a pump motor for spraying wash liquid against the dishes, depending upon the degree to which the wash liquid is soiled. The regulation of the pump motor adjusts the wash liquid spraying pressure.

Abstract: Disclosed is a washing machine with a float type clutch in which a float connects a rotating force from a motor to a spin-drying shaft or disconnects the rotating force from the spin-drying shaft as it is upwardly or downwardly moved in accordance with supply or drainage of wash water, thereby allowing a washing operation or a dehydrating operation to be carried out, while forming an air layer for preventing wash water from reaching gears included in the float type clutch.

Abstract: The present invention relates to a washing machine, which is capable of forcibly circulating water from the lower portion of a washing tub to the upper portion of the washing tub, thereby enabling circulation washing of the laundry. The washing machine includes a casing, a washing tub, an arrangement for holding the washing tub in the casing and an arrangement for forcibly circulating washing water. The washing tub is mounted in the casing. The holding arrangement serves to allow the washing tub to be positioned to be inclined at a predetermined angle with regard to a vertical axis. The water circulating arrangement forcibly circulates washing water from a bottom of the washing tub to a top of the washing tub and is extended from the bottom of the washing tub to the top of the washing tub.

Abstract: The present invention relates a washing machine of direct drive pulsator manner that is directly connected to a motor. In this washing machine, the conversion of cleansing/dehydrating processes can be smoothly achieved by a floatage clutch capable of being actuated by floatage and gravity to be induced during the supply/drain of water.

Abstract: Objects of the present invention lies on reduction of washing water quantity, and pressure loss of the washing water to the maximum by improving a flow passage of a medical instrument washer.

Abstract: A device for attenuating vibration of a drum type washing machine is provided which includes a balance chamber provided in an outer tub for temporary storage of extracted water during spinning for serving as a weight for attenuating vibration of the outer tub, means for supplying the extracted water to the balance chamber during spinning, and means for draining the extracted water from the balance chamber to outside of the washing machine on completion of the spinning, thereby permitting a significant savings in component production cost, and a light weighted washing machine for convenient transportation of the washing machine.

Abstract: The present invention relates to a dishwasher.

Abstract: Method for controlling washing during spinning in a tilt-type washing machine for attenuation of vibration, including (a) a main rotation step for exerting a centrifugal force to the laundry gathered to a center of the inner tub for spreading the laundry to an inside wall of the inner tub before the water discharging step, (b) a laundry disentangle alternately rotating step for alternately rotating the inner tub for a preset times to disentangle the laundry spread to the inside wall of the inner tub, and (c) a supplementary rotating step for rotating the inner tub at a preset RPM to keep the laundry in the tilted inner tub spread evenly during the water discharge step, or alternatively (a) a laundry disentangle alternately rotating step for alternately rotating the inner tub to eliminate the eccentricity of the laundry in the inner tub before the water discharge step, and (b) a determining step either for carrying out a control pattern to eliminate the eccentricity of the laundry if the eccentricity of the la

Abstract: Disclosed is a dishwasher including, a circulating pump for pressing and then supplying wash liquid, an injection arm for permitting the wash liquid pressed and supplied from the circulating pump to be injected by a predetermined passage structure, an underdrain container for collecting the wash liquid injected from the injection arm and supplying the collected wash liquid to the circulating pump, during a washing stage, a soil collecting chamber having a micro filter with a fine mesh for ramifying and finely filtering the wash liquid supplied from the circulating pump and returning the same to the underdrain container, during the washing stage, a drain pump for allowing the wash liquid to be drained through a drain passage which is extended from the underdrain container, and through a connecting passage which is extended from the soil collecting chamber and connected to the drain passage, during a draining stage.

Abstract: A washing machine with a tilted tub assembly is disclosed. In the washing machine, the tub assembly is suspended and supported within an upright housing at a predetermined angle relative to the perpendicular of the housing. The tilted position of the tub assembly within the housing is stably held by damper hangers, shock absorbing units and/or elastic support units. The tilted tub assembly is convenient to users while putting or taking laundry into or out of the tub assembly. The tilted tub assembly also forms complex and active water currents suitable for preventing laundry from being entangled during a washing operation. The washing effect of the washing machine is thus improved with a reduced deviation of the washing effect. The washing machine almost completely prevents its drive motor from being overloaded and conserves the operational time while washing laundry. This saves water and electric power during a washing operation.
