Abstract: A dishwasher uses washing water containing microbubbles. The dishwasher includes a flow path forming rib that defines a washing water flow path inside an upper body and a lower body of a spray arm. The dishwasher further includes a fusion rib for fusion coupling the upper body and the lower body to effectively secure a flow path structure and simplify a fastening structure.

Abstract: A dishwasher and a control method thereof are disclosed. The dishwasher includes a tub accommodating an object to be washed, a spray arm rotatably provided inside the tub to spray wash water toward the object to be washed, a sump for storing wash water and collecting wash water sprayed into the tub therein, a filter separably mounted to the sump to remove foreign substances from wash water, a wash pump for supplying wash water stored in the sump to the spray arm, and a circulation passage for diverting at least a portion of the wash water supplied to the spray arm by the wash pump to the sump. After the dishes are washed, all of the wash water introduced into the wash pump is diverted into the filter. Foreign substances present in the wash water are collected in the filter and are discharged outside along with the wash water.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.

Abstract: A dishwasher includes: a tub which defines a space in which dishes are washed; a sump which accommodates washing water to be supplied into the tub; and a descaling solution supply device which supplies a descaling solution to the sump, in which the descaling solution supply device includes: a main flow path which guides washing water to be supplied to the sump; a solution accommodating unit which accommodates a descaling agent and has a solution outlet through which washing water, in which the descaling agent is dissolved, is discharged to the main flow path; a solution discharge valve which opens and closes the solution outlet; and a branch flow path which branches off from the main flow path, supplies the washing water into the solution accommodating unit, and has an atmosphere communicating port that communicates with the atmosphere.

Abstract: A dishwasher is provided. The dishwasher may include a tub forming a washing space, a sump collecting washing water, a tank forming a storage space outside the tub, a motor generating a dynamic force to supply the washing water collected in the sump to the tank, and a controller incrementally increasing a water level of the tank by intermittently driving the motor.

Abstract: A dishwasher is provided. The dishwasher may include a case, a tub provided in the case and forming a dishwashing space, a re-using section provided inside the case and forming a space for storing wash water to be sprayed into the tub, and a water storing section provided inside the case and forming another space, separated from the re-using section, for storing externally supplied wash water.

Abstract: Provided is a dishwasher. The dishwasher includes a tub having a receiving space in which objects to be washed are received, a sump for storing wash water supplied into the tub, a heater that heats the wash water in the sump to generate steam, a steam nozzle for spraying the steam into the tub, a filter assembly that purifies the wash water supplied to the sump and communicates with the tub so that the steam generated in the sump is supplied into the tub and a barrier for dividing inner space of the sump into a first section communicating with the filter assembly and a second section communicating with the steam nozzle. The barrier allows the wash water flows between the first and second sections and suppresses flow of the steam from the second section to the first section.

Abstract: The present invention relates to a method for controlling a dishwasher. The method for controlling the dishwasher, including a sump for storing washing water collected from a tub and the washing water supplied from a raw water supply section, a washing arm for injecting the washing water at the sump into the tub, a washing pump for feeding the washing water at the sump into the washing arm, and a drainage pump for discharging the washing water at the sump outside, includes supplying the washing water to the sump; rinsing the sump by driving the washing pump and pumping the washing water until the washing water is injected from the washing arm; and dumping the washing water stored into the sump by driving the drainage pump after the rinsing for the sump. The method for controlling the dishwasher according to the present invention may clean the sump, thereby to save supply amount of the washing water, inject more clean washing water into the washes, and reduce rinsing time.
