Abstract: A defrosting apparatus includes: a heating unit including a heater case and a heater, where the heater case defines an inner flow path having an inlet and an outlet at ends thereof, and the heater is mounted in the heater case to heat a working fluid within the inner flow path; and a heat pipe inserted into the inside of the heater case through the inlet and the outlet, and which has at least a part thereof disposed to be adjacent to a cooling pipe of an evaporator such that heat is radiated to the cooling pipe of the evaporator by means of the working fluid at a high temperature that is heated by the heater and then is transferred, where the heater is configured to stop emit heat at a preset temperature or higher since an electric current is suppressed due to a sharp increase in resistance.

Abstract: A laundry treating apparatus includes a cabinet having a bottom plate that defines a bottom surface of the cabinet, a drum rotatably disposed inside the cabinet and configured to accommodate laundry, a hot air supply disposed at the bottom plate and configured to generate hot air to be supplied into the drum, a rear plate that defines a rear surface of the cabinet and includes a duct configured to receive the hot air from the hot air supply and to guide the hot air into the drum, a driver coupled to a rear side of the rear plate and configured to provide a rotational force to the drum, and a fan duct that is coupled to a front side of the rear plate and connects the hot air supply to the duct. The fan duct is configured to transfer the hot air of the hot air supply to the duct.
