Abstract: A dish washer includes a tub having a washing space defined therein for accommodating therein a dish; and a moisture-absorption and drying device configured to absorb moisture from air discharged from the tub and supply moisture-free air to the tub, wherein the moisture-absorption and drying device may include: a moisture absorbent for absorbing the moisture contained in the air; a housing for accommodating therein the moisture absorbent; and a heater having at least a portion received in the housing and configured to heat the moisture absorbent.

Abstract: The present invention relates to a dishwasher in which a blowing part, a heater part, and a absorbent, which constitute a sorption drying device, are arranged between a sump and a rear surface of a base so as to be as close as possible to the rear surface of the base and arranged in a long line in a leftward/rightward direction, such that the sorption drying device may effectively serve as a counterweight for preventing the dishwasher from falling over, and a volume and weight of a weight balance additionally provided may be reduced.

Abstract: A dish washer includes a heater for regenerating a moisture absorbent. A portion of the heater is received in a heater receiving portion, and the remaining portion thereof is received in an air introduction space under a moisture absorbent receiving space, such that air flow sufficiently heated by the heater may flow into the air introduction space, thereby reducing a possibility of local variation in the regeneration of the moisture absorbent, and the moisture absorbent is directly heated by radiant heat of the heater received in the air introduction space to improve heat emission efficiency and energy efficiency of the heater.

Abstract: A dish washer has a discharge flow path configured to carry air flow having passed through a moisture absorbent. The discharge flow path is defined between a cover of a moisture absorbent receiving space of a main housing and the moisture absorbent. The discharge flow path is configured to reduce non-uniformity in resistance against air flow having passed through the moisture absorbent inside the main housing and local non-uniformity in a moisture absorption amount to improve moisture absorption efficiency.

Abstract: A dishwasher includes a sorption drying device in which a heater is disposed in a linear air flow path extending in a downward inclination angle, at least a portion of air that has passed through the linear air flow path collides with a bottom surface of a moisture absorbent receiving portion and thus is introduced to a lower side of the moisture absorbent, so that a separate means for flow distribution is omitted, and heated air through the heater is evenly introduced to the moisture absorbent at a minimized flow resistance.

Abstract: A dishwasher includes a regeneration heater and a washing water heater that are controlled to operate simultaneously so that an operation period of the regeneration heater and an operation period of the washing water heater at least partially overlap each other, thereby heating the washing water and regenerating a moisture absorbent effectively and in a short time even in a washing course with a short washing cycle time.

Abstract: The present disclosure relates to a dishwasher equipped with an automatic cleaning filter including a tub 12 provided with a washing space 12a that accommodates cooking vessels, a sump 100 disposed under the washing space 12a and configured to store a washing liquid, an automatic cleaning filter 200 disposed in the sump 100, and a washing pump 150 connected to the sump 100 and configured to re-circulate a washing liquid. The automatic cleaning filter 200 includes a rotating filter 210, an inlet guide 220, a filter housing 230, and a driver 270. The rotating filter 210 includes a plurality of first holes 213 and a lateral surface portion 212 surrounding a predetermined vacant space. The inlet guide 220 includes a first outlet 224 which discharges the washing liquid including foreign substances into the rotating filer 210.

Abstract: Dishwashers and methods of control for operation of dishwashers are disclosed. The dishwasher may include an upper rack in an upper portion of a washing compartment configured to receive small dishes, such as a cup having a small washing load, and a lower rack in a lower portion of the washing compartment for placing large dishes, such as a dinner bowl having a large washing load. The operation of the dishwasher can include wash and rinse cycles having a plurality of sub-cycles. During the sub-cycles, the upper and lower racks can be selectively sprayed with water and steam can be supplied to the washing compartment based on configured conditions, such as a water temperature or operation time being reached. The operation of the dishwasher can reduce excessive washing of dishes having small washing loads and reduce power consumption of the dishwasher.

Abstract: The present invention relates to a dish washer in which a structure for mounting a drain pump is improved for minimizing residual water, vibration and noise. The dish washer includes a cabinet which forms an exterior of the dish washer, a tub in the cabinet to form a space for washing the dishes, a sump assembly at a lower portion of the cabinet, the sump assembly having a drain chamber for holding washing water to be drained, and a drain pump assembly coupled to a lower side of an outside of the sump assembly so as to be in communication with one side of the drain chamber for draining the washing water from the drain chamber by pumping, wherein the drain pump assembly is mounted tilted upward at a predetermined angle from an inside bottom surface of the cabinet.

Abstract: Dishwashers and methods of control for operation of dishwashers are disclosed. The dishwasher can include one or more racks in a washing compartment for placing used dishes having foreign matter, such as food and drink, and unused dishes having relatively little or no foreign matter and varying washing loads. Operation of the dishwasher can include wash, water drain and supply, and rinse cycles. During the cycles, preheating of a steam generator, water draining and supplying, steam supplying, and water spraying can occur and partially or fully overlap. The dishwasher can reduce excessive washing of dishes having small washing loads and improve power and water consumption.
