  • Patent number: 10492658
    Abstract: 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.
