An induction heating cooker and a control method thereof that stably adjust power of a cooking coil when a plurality of containers having different cooking conditions is placed on the cooking coil includes a plurality of heating coils disposed below a cooking plate and a controller to determine whether a container is placed on the heating coils, wherein the controller determines whether a plurality of containers is placed on one of the heating coils and, when the containers are placed on one of the heating coils, adjusts a power of the heating coil on which the containers are placed based on powers of other heating coils occupied by the containers. Cooking using a plurality of containers is stably performed based on user intention even when cooking conditions of the containers placed on a heating coil differ.

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 including a cooking plate on which a cooking vessel is placed, a plurality of heating coils disposed while being adjacent to one other below the cooking plate, and a Printed Circuit Board (PCB) on which circuits configured to drive the heating coils are placed, wherein the PCB is divided into a high frequency circuit part on which circuits characterized by high frequency are placed and a low frequency circuit part on which circuits characterized by low frequency are placed, and the high frequency circuit part is spaced apart from the low frequency circuit part by a predetermined distance. The interference between the high frequency circuit part and the low frequency circuit part is minimized while enhancing the operation efficiency of each heating coil. The assembly efficiency and the working efficiency are enhanced when an inverter circuit is wired to a corresponding heating coil.

Disclosed are a sensor, a cooking apparatus having the sensor, and a control method of the cooking apparatus. The sensor serves to accurately sense a pollution level of the cooking apparatus and to inform of a cleaning time and/or cleaning method based on the pollution level. The pollution level of a cooking compartment may be objectively determined using the sensor that senses the pollution level via a variation of capacitance. Also, it may be possible to guide a cleaning time and/or cleaning method (e.g., manual cleaning, steam cleaning, thermal decomposition cleaning, etc.) based on the pollution level of the cooking compartment, allowing the cooking compartment to be cleaned in the cleaning method at an appropriate cleaning time. In particular, during a thermal decomposition cleaning operation, the pollution level is sensed in real time to enable variable control the cleaning time and automatic control of a cleaning ending time. This may contribute to reduce energy consumption and discharge of CO2.

The water level sensing unit includes a sensing member having a sensor, the sensing member being installed at a side of the steam container, and a pivoting member having an extension adapted to pivotally rotate about a side thereof having a fixed position on the basis of the level of water. The sensor is adapted to sense positional variation of the extension, to thereby sense variation of the level of water in the steam container.

A microwave oven, having a humidity sensor and a voltage detecting unit for detecting a change in an output voltage of the humidity sensor, includes: a control unit for receiving a compensated voltage according to a change in temperature supplied from the humidity sensor and a detected voltage supplied from the voltage detecting unit, and determining a cooking time based on a voltage difference between the detected voltage and the compensated voltage. With this configuration, an optimal cooking time based on a being cooked can be calculated by use of the humidity sensor, and the cooking time can be controlled in a stable manner relative to external noise or irregular changes in humidity.

A magnetron, and a microwave oven and a high frequency heating apparatus each equipped with the same use, a single permanent magnet disposed above or below an anode, a pole piece near the permanent magnet that has a magnetic flux dispersing structure, and another pole piece opposite to the permanent magnet that has a magnetic flux concentrating structure. In accordance with the present invention, even though a single permanent magnet is provided, magnetic flux density is rendered uniform across an activating space, so that the volume and parts of the magnetron are reduced and the curtailment of manufacturing costs is realized.
摘要:
An apparatus and a method automatically cook food, for example, millet, thus conveniently providing the uniform and optimal cooking quality of food to a user. The cooking apparatus includes a cooking cavity that contains food to be cooked and water therein, and a heating unit that heats the food and the water. The cooking apparatus further includes a control unit operated to heat the food and the water at a preset initial output of the heating unit, to reduce the output of the heating unit to a first reduced output and cook a surface of the food by allowing a heated high temperature water to be absorbed into the food after the water has boiled, and to reduce the output of the heating unit to a second reduced output and cook an inside of the food using the high temperature water absorbed into the food.
摘要:
A microwave oven includes a humidity sensor, a main-outlet and a sub-outlet formed at opposite sidewalls of a cooking cavity such that the cooking cavity communicates with the atmosphere through the main-outlet and the sub-outlet. The sub-outlet is installed in a machine room adjacent an air inlet side of a cooling fan. The humidity sensor is installed in the machine room at a position adjacent to the sub-outlet and senses the humidity of air inside the cooking cavity by sensing the humidity of a part of the air discharged from the cooking cavity through the sub-outlet. The surface of the humidity sensor is less likely to be easily contaminated by the air exhausted from the cooking cavity, moisture deposited on the surface of the humidity sensor 60 is quickly evaporated so that the humidity sensor performs its desired operation even when the microwave oven sequentially performs several cooking processes.
