DISHWASHER

Description

TECHNICAL FIELD

The present disclosure relates to a dishwasher, and more specifically, to a rack disposed inside a tub.

BACKGROUND ART

A dishwasher is a machine that sprays washing water and steam on tableware placed inside a tub to keep the tableware clean and sanitary.

A rack may be disposed inside the tub so that tableware is seated thereon, and a plurality of racks may be disposed to be vertically spaced apart from each other.

However, when the plurality of racks are disposed in the vertical direction, tableware on the uppermost rack may interfere with an upper portion of the tub, thus causing damage to the tableware.

Further, even if a portion of the rack is raised and lowered in the vertical direction to prevent interference between the tableware and the tub, there is a problem in that a portion of the rack that is raised and lowered is detached from the rack and thereby the tableware is damaged.
