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: The present invention relates to a microwave oven including a cavity having a certain area for cooking comprising a flow path formed between a main body and the cavity so as to be connected from a side of the cavity to the upper surface of the cavity, a heater installed on the side of the flow path corresponding to the outer upper surface of the cavity for emitting heat, a discharge hole installed on the upper surface of the cavity corresponding to the lower portion of the heater for discharging the heat of the heater into the cavity, an inlet installed on the lower portion of the side wall of the cavity for making the air inside of the cavity flow in the flow channel, and a circulating fan installed on a certain portion of the flow channel for circulating the air inside of the cavity flown through the inlet to the heater.

Abstract: The present invention relates to a device capable of cooking food products in a short time so as to concentrate the emitted light on the food product using a lamp emitting light in an infrared region. More particularly, it is capable of cooking the food product in a short time by concentrating light in the visible light region within a wavelength range of more than 1.35 &mgr;m on the food product using a luminous unit for emitting light in the infrared light region and a reflecting plate for concentrating the emitted light in the infrared light region.

Abstract: A halogen heater control apparatus of a microwave oven and a method thereof, comprises a plurality of halogen heaters which are connected to a utility AC power source, and a halogen heater switching unit. The halogen heater and incrementally alters infrared wavelengths from the halogen heater, and a microcomputer controls the operation of the halogen heater switching unit. The present invention is capable of optimum foodstuff heating and cooking by incrementally altering and controlling the infrared wavelengths from the halogen heater by controlling the utility AC power source duty cycle to the halogen heater in accordance with control signals generated by the microcomputer.

Abstract: The present invention relates to a microwave oven including a cavity having a certain area for cooking, a magnetron installed at the outside of the cavity for generating microwave, a waveguide installed at the side of the magnetron and its end extended inside of the cavity for transmitting the microwave inside of the cavity. The microwave oven comprises a bidirectional flow channel formed inside of the waveguide for transmitting microwave selectively inside of the cavity in accordance with cooking function, a microwave plate combined to inside of the waveguide so as to be rotational for guiding the microwave to selected direction between the two direction of the flow channel, and a plasma lamp installed adjacent to the side of the bidirectional flow channel for generating radiant energy by being heated by the microwave.
