Abstract: A heating device having an improved heat resistance structure is provided. The heating device may include a heating element that generates heat, and an elastic conductive part that applies electricity to the heating element. A connector may be provided between the elastic conductive part and the heating element to preclude direct contact between the heating element and the elastic conductive part. The heating element may be fixed to one side of the connector, and the elastic conductive part may be fixed to the other side of the connector to allow current applied from the elastic conductive part to flow to the heating element.

Abstract: A burner for a glass top stove includes a heating element, and a reflector. The reflector is shaped to reflect heat and light emitted down and to the sides of the heater back up to the glass top of the burner. The reflector is shaped to form multiple images of the heater on the glass plate. This ensures uniform heating of the glass plate. It also causes a user to believe that there are more heaters than are actually mounted on the burner.

Abstract: A heater supporter for use in a cooking apparatus is provided. The heater supporter may include a clip portion that receives a heater, an extension portion that supports the clip portion, and a hook portion that couples the heater supporter to an installation plane of the heater. The extension portion may include an elastic portion that elastically supports the clip portion and heater therein, and maintains at least a predetermined distance between the heater and the installation plane. The heater supporter may be formed of a single panel to simplify fabrication and reduce cost.

Abstract: Disclosed herein is a blowing apparatus for refrigerators. The blowing apparatus includes a centrifugal fan. The centrifugal fan comprises a hub plate connected to a shaft of the motor, a plurality of blades attached to the hub plate in the radial direction of the hub plate for forcing cool air to flow, and a ring-shaped shroud connected to ends of the blades. The ratio of the inner diameter of the centrifugal fan, formed through connection of the inner ends of the blades, to the outer diameter of the centrifugal fan, formed through connection of the outer ends of the blades, is 0.63±0.01. With the blowing apparatus for refrigerators according to the present invention, flow loss is minimized. Consequently, the present invention has the effect that energy consumption is reduced, noise is decreased, and thus the refrigerator is quietly operated.

Abstract: A heating unit includes a heater that generates radiant heat, and a reflector that reflects radiant heat generated by the heater toward an object. The reflector includes a side portion shaped as an involute, a central elevated portion of a predetermined height, and a connecting portion that connects the side portion to the elevated portion. A supporter supports the heater in a position spaced from the reflector by a predetermined distance.

Abstract: An electric cooker having a composite heat source comprising: an external case having an air inlet and an air outlet; a cooking plate on an upper surface of the external case to be a top plate; a heat generating unit including a work coil and/or an electric heater, mounted between the external case and the cooking plate for coaxial arrangement with the air inlet; and a heat radiation unit including a fan motor and air ducts, coaxially arranged between the air inlet and the heat generating unit, such that sufficient cooling effect can be achieved even with a small-sized blow fan of a small capacity. The manufacturing cost can be reduced, and an effective utilization of space for parts arrangement can be enhanced using the relatively small capacity of blowing fan, enabling to manufacture an electric cooker in a thin, light, simple and compact manner.

Abstract: A cooker is disclosed, the cooker comprising: a case having an air inlet and an air outlet; a cooking plate provided on the case; a heating unit formed between the case for heating the cooking plate and the cooking plate; and a cooling unit for cooling the cooking plate by introducing outside air into the air inlet, letting it circulated around the cooking plate, and discharged via the air outlet, such that the cooling time of the cooking plate can be shortened.

Abstract: An over-the-range (OTR) microwave oven includes a main body installed above a cooking source of a gas range and has therein a cavity and an electric equipment chamber in which a magnetron is located. An air exhaust path is installed inside the main body and provides a path through which air generated from the cooking source which is introduced through a suction port formed at the bottom of the main body by a suction force of a blower installed at the main body is exhausted to the outside of the main body.

Abstract: The invention relates to an axial flow fan for condenser in a refrigerator for enhancing efficiency and lowering noise, in which the number of blades is three, the diameter of a hub is 23.3±5% of the outside diameter of the axial flow fan and the width of each of the blades is 36.6±3% of the outside diameter of the axial flow fan.

Abstract: A cooling air blowing apparatus of a refrigerator includes: a driving motor fixed at a motor mount formed at a rear side of a freezing chamber; a blowing fan mounted on a rotational shaft of the driving motor and configured to blow cooling air in both an axial and a radial direction as the driving motor is driven; and a shroud positioned in a circumferential direction of the blowing fan. The blowing fan includes turbo blades for blowing cooling air in a radial direction in addition to the axial flow blade for blowing cooling air in an axial direction. The cooling air blown in the axial direction is sent to a freezing chamber, while the cooling air blown in the radial direction is sent to the cooling chamber. Thus, the blowing fan with the turbo blades ensures that in a refrigerator having a complicated and long cooling air passage structure, cooling air can be circulated smoothly and quickly.

Abstract: A cooling air blowing apparatus of a refrigerator includes: a driving motor fixed at a motor mound formed at a rear side of a freezing chamber; a blowing fan mounted at a rotational shaft of the driving motor and blowing cooling air in a suction direction along the axis direction and blowing cooling air in a suction direction along a radial direction, while being rotated as the driving motor is driven; and a shroud positioned in a circumferential direction of the blowing fan.
