  • Patent number: 10648114
    Abstract: A wall-mounted washing machine with a built-in drying device operable to generate hot air during drying processes. The washing machine includes a rear panel configured to be affixed to a wall surface and support the tub. The rear panel includes one or more vent holes that allow hot air existing in a space between the rear panel and the housing of the washing machine to be discharged outside. By promptly removing hot air from the vicinity of the housing, the internal temperature of the washing machine can be effectively controlled and various components in the washing machine can be protected from unintended heating by the hot air.

  • Patent number: 10443914
    Abstract: An ice-making device for a refrigerator including a duct providing a cold air flow path under an ice tray in which water turns into ice pieces. Uneven portions extending in a direction differing from a flow direction of cold air are formed at a lower surface of the ice tray. The duct may have a wavy surface. The surface features of the ice tray and the duct can advantageously increase contact area and contact time between cold air and the ice tray, thereby increasing the heat exchange efficiency between cold air and water contained in the ice tray.
