  • Patent number: 10980395
    Abstract: A dishwasher capable of shortening drying time is disclosed. The present device comprises: a main body having a washing tub provided therein; a door rotatably coupled to the main body so as to open and close the washing tub; a blowing duct having a passage provided between the outside of the washing tub and the inside of the main body so as to provide a flow path through which the air flowing from the outside flows, and a discharge port provided at the passage so as to spray air to the outside; and a blowing means connected to the blowing duct so as to provide the external air into the blowing duct, and forcibly causing wet steam in the washing tub to flow to the front of the main body, wherein the passage has at least one variable section for changing the cross sectional area thereof.

  • Patent number: 10883296
    Abstract: A washing machine comprises a hinge device including a cam member, a lever, and an elastic member, and the cam member comprises an outer circumference surface including a first section, a second section and a third section disposed between the first section and the second section having a curvature different from each other. The cam member is profiled to be disposed at a first position in which the door is automatically opened, a second position in which the door is automatically closed, and at a third position in which an external resultant force becomes 0 (zero), when the lever is in contact with each section. Therefore, it is possible to control a closing speed of the door and simplify the power transmission method by using the cam, reduce the material cost by reducing the number of parts, and secure the reliability of driving of the washing machine.
