Abstract: A machine room cooling structure of an oven which relatively enlarges the inner volume of a cooking room by lowering the height of the machine room is provided. The machine room cooling structure includes a fan forcibly blowing air of the machine room, a motor driving the fan, an exhaust duct guiding air of the machine room to an area in front of the oven, and a support bracket to install the motor at a suction hole of the exhaust duct, the support bracket includes a base unit, a motor combining unit on which a core of the motor is placed, and bridge parts connecting the base unit and the motor combining unit, and the motor combining unit is formed such that the height of the lower end of the core is equal to or lower than the height of the upper end of the exhaust duct.

Abstract: A tray for a microwave oven and a microwave oven having the same is disclosed. Heat generators are formed on the surface of a tray unit of the tray for a microwave oven through transfer coating carried out at a high temperature, and thus the tray for a microwave oven may be heated to a high temperature, thereby being capable of effectively forming a grill mark on food to be cooked.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A controlling method and system for a damper clutch of an automatic transmission control a damper clutch release condition according to a direct connection status of a damper clutch. The controlling method includes: determining whether the damper clutch is in a direct connection status in a power-on state or a direct connection status in a power-off state; detecting information of a vehicle if the damper clutch is in the direct connection status of the power-on or power-off state; determining whether a release condition of the damper clutch is satisfied; and releasing the damper clutch if the release condition of the damper clutch is satisfied.
