  • Patent number: 6810684
    Abstract: Object of the present invention is to improve a structure of the air conditioner, to provide an air conditioner which can dispose of condensed water from an evaporator within the air conditioner itself without discharging to outside of the air conditioner, and improve an air conditioner efficiency. To achieve the object of the present invention, the air conditioner of the present invention includes a condenser which generates a high temperature heat, an evaporator which absorbs an external heat, and forms condensed water on a surface thereof by a temperature difference with an external air, and condensed water self disposal means for transferring the condensed water on the surface of the condenser to a condenser side, and evaporating the condensed water from the surface of the condenser by the high temperature heat from the condenser, thereby disposing of the condensed water within the air conditioner itself.

  • Patent number: 6677564
    Abstract: A blower apparatus which is used inside an Over-The-Range (OTR) microwave oven and the like, includes a centrifugal fan, a bracket which is fixed and combined with a side of the driving unit and a fan housing having a suction port which rotably accommodates the centrifugal fan, is fixed and combined with the bracket, and is formed in the shaft direction of the centrifugal fan, for sucking gas by rotation of the centrifugal fan, and a discharge port for discharging gas which is sucked through the suction port, being formed vertically to the suction port. The edge of the discharge port is formed in a convex shape in the shaft direction by the first inclined surface of a protrusion portion which is protruded in the shaft direction from the bracket and second inclined surface formed in the fan housing, and an inflection point is formed at the contact point of the first inclined surface and second inclined surface.
