Abstract: A magnetron for a microwave oven is provided that decreases noise in an ISM band by minimizing a size of a lower end shield, and thus, minimizing EMI generation. In the magnetron for the microwave oven, as a midpoint of a side lead hole is positioned inside a virtual circle formed by points positioned at a predetermined distance from a midpoint of the shield disc and a side lead is connected in a straight line, there are advantages that a further bending process is not generated and a defective rate that occurs in the manufacturing process of the shield disc may be decreased.

Abstract: A cooking device is provided. The cooking device may include a cavity forming a space in which food may be received for cooking, a grill heater provided at one side of the cavity and having a plurality of heaters to heat the food, a food sensing device provided in the cavity to acquire information related to a size of the food received in the cavity, and a main controller to estimate the size of the food using information sensed by the food sensing device. The main controller may then operate a part or all of the plurality of heaters according to the estimated size of the food to perform a grill cooking operation.

Abstract: An artificial intelligence cooking device includes a plate including a heater configured to heat ingredients in a cooking vessel placed on the plate; a vibration sensor disposed below the plate configured to detect a vibration signal of the ingredients in the cooking vessel transmitted through the plate; and a processor configured to determine, via an artificial intelligence model having learned properties of the vibration signal, whether or not the ingredients in the cooking vessel are boiling based on the detected vibration signal provided to the artificial intelligence model and the learned properties of the vibration signal; and output information indicating whether or not the ingredients are boiling based on the determination.
