20090020516 | COOKING DEVICE - A heating cooking device includes a top plate, a heating unit, a touch key including a first electrode and a second electrode, an input unit for applying an alternating current (AC) voltage to the second electrode and for outputting a voltage changing according to a change of the AC voltage when the first electrode is pushed, a detector for outputting a first signal if the voltage output from the input unit changes from the reference value to the first value, an operation judging unit for outputting a second signal according to a rate of change of the voltage output from the input unit, and a controller operable to perform control of the heating unit based on the first and second signals. The controller is operable to perform control of energization of the heating unit if the controller does not receive the second signal after receiving the first signal, and not to perform the control of the energization of the heating unit if the controller receives the second signal after receiving the first signal. | 01-22-2009 |
20090127248 | HEATING COOKER - When a timer period reaches an increase-stopping-time during the long-push state of a timer key, increase of the timer period is stopped once. Accordingly, even though a long-push state is continued due to a fault of the timer key, the indication of the timer period is not repeated. | 05-21-2009 |

20100181299 | INDUCTION COOKER - There is provided an induction cooker capable of detecting failures in an infrared ray sensor with excellent accuracy. The induction cooker includes an infrared-ray detection unit ( | 07-22-2010 |
20100187216 | COOKING DEVICE - There is provided a cooking device capable of preventing heating operations from being unintentionally turned on and off and the setting of heating operations from being changed even when water droplets are scattered around touch switches or the vicinity of the touch switches is wiped with a damp cloth or the like. Left and right cancel electrodes ( | 07-29-2010 |
20100243641 | INDUCTION HEATING COOKER - An induction heating device according to the present invention includes an infrared ray sensor for detecting infrared rays radiated from a cooking container through a top plate, a light emitting device which is placed near the infrared ray sensor and emits light to the back surface of the top plate, and a heating control unit which controls a high-frequency current through a heating coil for controlling the heating of the cooking container. When the heating control unit has stopped the heating of the cooking container, and a predetermined time elapses at the heating-stopped state, the light emitting device is controlled to stop the light emission therefrom. This can improve durability of the light emitting device, which enables maintaining a function of clearly indicating a position at which the cooking container should be placed and a function of detecting failures in the infrared ray sensor, which are roles of the light emitting device. | 09-30-2010 |
