A dish washing machine having a structure allowing wash water to be evenly sprayed into a washing tub. The dish washing machine includes a cabinet forming an external appearance of the dish washing machine, a washing tub arranged in the cabinet and allowing dishes to be washed therein, a dish basket arranged in the washing tub to accommodate the dishes, a spray unit to spray wash water into the washing tub, a diversion unit arranged inside a flow passage of wash water to divert the wash water sprayed from the spray unit, and a guide member coupled to one side of the diversion unit to allow the diversion unit to move within the washing tub. As the spray unit and the diversion unit are provided, a dead zone which wash water does not reach may be eliminated, and divided and intensive washing may be implemented in the washing tub.

A dishwasher provided that may include a washing chamber, a rack adapted to accommodate items to be washed by washing liquid within the washing chamber, an arm, and an arm moving arrangement arranged to move the arm within the washing chamber. The arm may include at least one washing liquid removing element arranged to touch at least one of the rack and washing liquid at the rack upon movement of the arm to remove the washing liquid from the rack. The embodiments herein also relate to method for removing washing liquid from a rack of a dishwasher.

A lock and a home appliance having the same are disclosed. The lock includes a holder provided at one selected from between the cabinet and the door, a housing provided at the other selected from between the cabinet and the door, a first stopper provided at the housing, a fastening unit separably coupled to the first stopper so as to be coupled to the holder when separated from the first stopper, an actuation unit configured to reciprocate in the housing, the actuation unit being configured to be moved away from the introduction port in the state of contacting the holder when the door is moved so as to close the introduction port, the actuation unit being configured to separate the fastening unit from the first stopper while being moved away from the introduction port, a first elastic member for providing force necessary to move the fastening unit away from the introduction port when the fastening unit is separated from the first stopper, a second elastic member for providing force necessary to move the actuation unit toward the introduction port, and an actuation unit lock for fixing the actuation unit to the housing when not in contact with the door and releasing coupling between the actuation unit and the housing when in contact with the door.

A cup washer includes a tub providing a space in which a cup is accommodated, and a sprayer disposed on the tub and configured to spray water toward the cup. The sprayer includes a first spray nozzle and a second spray nozzle coupled to the first spray nozzle. The second spray nozzle is disposed on a central portion of the first spray nozzle. The first spray nozzle extends away from an outer circumference of the second spray nozzle. The first spray nozzle is rotatable around the second spray nozzle.

The dishwasher of one embodiment comprises a tub, a sump, a wash pump, a rack, a nozzle disposed at a lower end of the rack, rotated by a repulsive force of wash water supplied from the wash pump, spraying wash water to a wash target, and having a magnetic object coupled to one end of the nozzle so that a first pole and a second pole of the magnetic object face a rotation direction of the nozzle, a sensing module that senses a magnetic force generated by the magnetic object generated by a rotation of the nozzle, and a controller receiving sensing results from the sensing module, and determining one or more of a rotation direction of the nozzle, a rotation speed of the nozzle and whether the nozzle rotates, to output an abnormality notification to a user or control wash water supplied to the nozzle through the wash pump.

A dishwasher for treating dishes according to a cycle of operation, the dishwasher having a tub at least partially defining a treating chamber, a dish rack having a first wash zone and a second wash zone, and a spray tube having at least one set of nozzles and rotatable between a first position and a second position.

A dishwasher including a washing tub having a bottom plate having an opening, a nozzle having a spraying hole configured to spray water, the nozzle passing through the opening, and a sealing member configured to seal the opening. The bottom plate includes a base portion on which the nozzle is installed, and a protruding portion extending downward from the base portion to form the opening, the nozzle includes a support portion on the base portion, and a nozzle side portion facing the protruding portion. A part of the support portion contacts the base portion and another part of the support portion is spaced apart from the base portion according to an inclination of the base portion, where the sealing member is disposed between the protruding portion and the nozzle side portion. The spraying trajectory of the water can thus be kept constant despite the inclination deviation of the base portion.
