A cooker including a first coating layer that is a general ceramic enamel layer and a second coating layer that includes phosphorus oxide-based components are coated on a surface of a cavity corresponding to the inner surface of the cooking chamber. Therefore, the inside of the cooking chamber can be more easily cleaned.

Cooker

A cooker and methods of manufacturing and controlling the same. The cooker including a first coating layer that is a general ceramic enamel layer and a second coating layer that includes phosphorus oxide-based components are coated on a surface of a cavity corresponding to the inner surface of the cooking chamber. Therefore, the inside of the cooking chamber can be more easily cleaned.

Cooker and method of manufacturing and controlling the same

A cooking appliance includes a heat source; an input unit configured to input a plurality of operational modes of the heat source for cleaning a cavity; and a control unit configured to operate the heat source in accordance with a mode input through the input unit, wherein the input unit comprises a selection unit configured to select a specific mode of the plurality of operational modes.

Cooking appliance and method of controlling the same

The present invention includes a cooking appliance with an enamel composition. The enamel composition includes a heat resistance, chemical resistance, wear resistance, and pollution resistance, such that the cooking appliance withstands high temperature, acid or alkali and is readily cleaned.

Cooking appliance

A microwave signal generator includes a magnetron to generate a microwave signal, a coupler to receive the microwave signal generated by the magnetron and to send the microwave signal to a load; and a band-pass filter to receive the microwave signal from the coupler and to filter the microwave signal to obtain a signal from an oscillation frequency band of the magnetron. The band-pass filter feeds the signal from the oscillation frequency band back to the magnetron in order to fix an oscillation frequency of the magnetron and is a DR (Dielectric Resonator) filter.

Microwave signal generator

Disclosed herein is a magnetron. The magnetron comprises an anode cylinder, upper and lower magnets provided to upper and lower portions of the anode cylinder, and upper and lower magnetic poles connected to the magnets, respectively. Each of the magnets has an inner diameter of 19&#x2dc;21 mm, a thickness of 11.5&#x2dc;12.5 mm, and an outer diameter of 50&#x2dc;54 mm.
