Abstract: A washing apparatus and control method where the washing apparatus comprises a door configured to open and close the entrance; a tub inside a main body; a diaphragm configured to connect the entrance with the opening; and a drum rotatably provided inside the tub. The washing apparatus includes a door washing nozzle to inject water for a first time in a first section and then to inject the water for a second time in a second section when a washing mode of the diaphragm is entered. The washing mode of the diaphragm including the first section in which the drum in a stopped state is accelerated to arrive at a first target rotation speed less than a second target rotation speed and the second section in which the drum at the first target rotation speed is accelerated to arrive at the second target rotation speed.

Abstract: A dishwasher, in which a reservoir provided with an electrolyzer is connected to a water collector via a flow path change valve, and wash water in the reservoir is electrolyzed by the electrolyzer during non-operation of the wash water, to generate sterilizing water and to circulate the sterilizing water into the dishwasher, thereby achieving an enhancement in sterilizability of the dishwasher. A method for controlling a dishwasher makes it possible to suppress propagation of microorganisms left in the dishwasher and to remove organic substances, using a sterilizing agent or high-temperature water. It is also possible to reduce generation of offensive odor caused by decomposition of bacteria, through a reduction in the amount of bacteria in the dishwasher. Since sterilization of the dishwasher is automatically carried out, enhanced user convenience is provided.

The door washing nozzle is controlled to inject the washing water for a first time in a first section and inject the washing water for a second time in a second section when a washing mode of the diaphragm including the first section at which the drum in a stopped state arrives at a first target rotation speed and the second section at which the drum rotated at the first target rotation speed arrives at a second target rotation speed.

Abstract: A dishwasher including a washing chamber to wash dishes, a sump concavely formed at a lower portion of the washing chamber to collect water used in washing, a microfilter disposed at the sump to filter out dirt produced when the dishes are washed, and an ultrasonic generator to radiate ultrasonic waves toward the microfilter. Since the microfilter is automatically cleaned by the ultrasonic generator, a user may not need to manually clean the microfilter.
