A refrigerator includes a first storage compartment, a cavity, a heat source, a cold source, a water molecule freezing preventing device, and a controller configured to control an output of at least one of the heat source, the cold source, or the water molecule freezing preventing device. The controller is configured to perform a first operation step to operate based on the first set temperature for a cooling operation, a second operation step to operate based on a second set temperature for a heating operation, and a third operation step to operate based on a third set temperature for the cooling operation, where the second set temperature is higher than 0° C., and the third set temperature is equal to the first set temperature.

Refrigerator

A refrigerator includes a first storage compartment, a heat source, a cold source, a water molecule freezing preventing device, and a controller configured to perform a first operation based on a first notch temperature for a first cooling operation, a second operation based on a second notch temperature for a heating operation, and a third operation based on a third notch temperature for a second cooling operation. The second notch temperature is higher than 0° C., and the third notch temperature is higher than the first notch temperature. Accordingly, it may be possible to efficiently supply the cold or heat until reaching a supercooling maintenance section.

A refrigerator according to an embodiment of the present disclosure includes a first storage compartment, a cavity, a heat source, a cold source, a water molecule freezing preventing device, and a controller configured to control an output of at least one of the heat source, the cold source, or the water molecule freezing preventing device, wherein the controller is configured to perform a first operation step to operate based on the first notch temperature for a cooling operation, a second operation step to operate based on a second notch temperature for a heating operation, and a third operation step to operate based on a third notch temperature for the cooling operation, the second notch temperature is higher than 0° C., cold in the first storage chamber increases in the first operation step and the third operation step, and the cold decreases in the second operation step. Accordingly, it is possible to efficiently supply the cold or heat until reaching a supercooling maintenance section.

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.

Artificial intelligence cooking device

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.

Magnetron for microwave oven

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.

Cooking device and method of controlling the same

Provided herein are a cooking apparatus and an operating method thereof. The cooking apparatus includes a cavity, a microwave generator to generate and output microwaves of a plurality of frequencies to heat an object within the cavity, and a controller to calculate interpolated microwave frequencies for a heating session, based on microwave frequencies calculated during a scanning session, and to calculate heating times of the interpolated microwave frequencies. Thereby, operating efficiency of the cooking apparatus is improved.

Cooking apparatus and operating method thereof

Provided herein are a door choke and a cooking apparatus including the same. The cooking apparatus includes a front plate forming the front surface of a cavity, a door to open and close the cavity, and a door choke including a first attachment member attached to the door and including at least two bent parts and a second attachment member attached to the door and including at least two bent parts so as to be separated from the first attachment member to form a space, and a bending direction of the first attachment member and a bending direction of the second attachment member are opposite to each other. Thereby, effective electromagnetic interference shielding is achieved.
