摘要:
A microwave oven includes a magnetron to generate microwaves and a cooking chamber to contain food to be cooked using the generated microwaves. The microwave oven further includes a humidity detector to detect moisture formed from the food being cooked. The humidity detector is provided at air outlets of the cooking chamber, and includes first and second electrodes formed on a board to be space apart from each other at a predetermined interval to form a gap therebetween. The control unit of the microwave oven controls the cooking operation of the microwave oven according to the output of the humidity detector.
摘要:
A polymer-type humidity sensor for use in a microwave oven and which has a polymer structure which includes a rubber and a predetermined amount of carbon, and a pair of electric terminals connected to the polymer structure. The polymer-type humidity sensor of the present invention has a rapid response time, durability, excellent adherence to terminals, low hysteresis, and exhibits stability to exposures of high temperatures and high relative humidity.

An induction heating cooker and a control method thereof that prevents the occurrence of an error caused during recognition of a container in the induction heating cooker that performs cooking regardless of where the container is placed on a cooking plate includes a plurality of heating coils disposed below a cooking plate, current detectors to detect values of current flowing in the respective heating coils, and a controller to determine whether a container is placed on the respective heating coils based on the detected current values of the heating coils and change amounts of the current values.
摘要:
An induction heating cooker includes a plurality of heating coils to heat a container, an inverter having a plurality of switching elements to be operated such that a high-frequency voltage is selectively supplied to the plurality of heating coils, and a control unit to control the operations of the plurality of switching elements such that the high-frequency voltage is time-divisionally supplied to a heating coil, on which the container is positioned, among the plurality of heating coils. By this configuration, it is possible to reduce the number of inverters and manufacturing costs. In addition, since the thickness of the cooker is reduced, it is possible to reduce the overall size of the cooker.
摘要:
Disclosed herein is a control method of an induction heating cooker including detecting at least one heating coil occupied by a first container from among a plurality of heating coils, switching a plurality of inverter units so that a power level input by a user is applied to the detected at least one heating coil, determining, if the at least one heating coil occupied by the first container includes plural heating coils, whether or not output currents within a target output current range corresponding to the power level are present from among the output currents of the respective heating coils sensed by sensing units, and equally adjusting duty ratios of pulse width modulation signals applied to the inverter units of the respective heating coils until at least one of the output currents reaches the target output current range, if no output current within the target output current range is present.
摘要:
An induction heating cooker including a temperature sensor disposed between a plurality of working coils which are uniformly disposed below a cooking table and a heat transfer member to transfer heat from the working coils adjacent to the temperature sensor to the temperature sensor, thereby improving productivity and space utilization.
摘要:
A steam generator capable of preventing scale contained in air bubbles and water droplets generated in the course of boiling water by a heater from entering a steam ejection hole and a heating cooking apparatus having the steam generator is provided. The steam generator includes a steam container to store water and having at least one steam ejection hole formed at an upper location thereof, a heater adapted to heat the water stored in the steam container so as to generate steam, and a barrier unit provided below the steam ejection hole and adapted to prevent the air bubbles from entering the steam ejection hole. The barrier unit includes a base plate having a plurality of steam passage holes and a web plate coming into close contact with an inner wall surface of the steam container.
摘要:
A coating composition and a cooking device and/or cooking receptacle coated with the coating composition are described. The coating composition includes 10 to 30 wt. % of SiO2, 10 to 30 wt. % of P2O5, 10 to 30 wt. % of Al2O3, 1 to 20 wt. % of TiO2, 7 to 15 wt. % of Na2O, 7 to 15 wt. % of K2O, 5 to 10 wt. % of ZrO2, 2 to 5 wt. % of BaO, 2 to 5 wt. % of B2O3, 1 to 2 wt. % of MnO2, and an adhesion enhancer. The coating composition provides favorable thermal resistance, acid resistance and mechanical properties, such that a cooking device and/or receptacle coated with the coating composition may be easily cleaned at a relatively low temperature.
