Abstract
An apparatus and method for controlling an output of a magnetron of a microwave oven is provided. The method includes setting an initial input current to generate an output higher than rated output. Thereafter, the magnetron is driven using initial input current of the setting. The output of the magnetron is varied within a preset time to prevent overheating caused by driving of the magnetron.
Claims23
A method of controlling an output of a magnetron of a microwave oven, the microwave oven normally driving the magnetron to generate rated output using rated current, comprising:
- setting an initial input current to generate an output higher than a rated output of the magnetron;
- setting an initial preset time after which the initial input current is changed to the rated current, the initial preset time being within a usable time of a power fuse;
- driving the magnetron using the initial input current of the setting;
- and
- varying the output of the magnetron after the initial preset time has elapsed to prevent overheating caused by the driving of the magnetron.
An apparatus controlling an output of a magnetron of a microwave oven, the microwave oven controlling the output of the magnetron by adjusting current inputted to the microwave oven, comprising:
- a current detecting unit detecting anode current passing through an anode of the magnetron;
- and
- a microcomputer setting an initial input current inputted to the microwave oven, controlling the magnetron to generate an output higher than a rated output of the magnetron for a preset time based on the anode current detected by the current detecting unit and changing the input current to a rated current after the preset time has elapsed,
- wherein the preset time is set to be within a usable time of a power fuse.
A method of controlling an output of a magnetron of a microwave oven, comprising:
- setting an initial preset time after which an initial input current is changed to a rated current, the initial preset time being within a usable time of a power fuse;
- driving the magnetron at the initial input current greater than the rated current of the magnetron;
- and
- adjusting the initial input current of the magnetron, after the initial preset time has elapsed, to less than the initial input current to prevent overheating of the magnetron.
An apparatus controlling an output of a magnetron of a microwave oven, the microwave oven having a current detecting unit detecting anode current passing through an anode of the magnetron and controlling the output of the magnetron by adjusting current inputted to the microwave oven, comprising:
- a controller setting an initial input current inputted to the microwave oven, controlling the magnetron to generate an output higher than a rated output of the magnetron for a preset time based on the anode current detected by the current detecting unit and changing the input current to a rated current after the preset time has elapsed,
- wherein the preset time is set to be within a usable time of a power fuse.
An apparatus controlling an output of a magnetron of a microwave oven, the microwave oven having a current detecting unit detecting anode current passing through an anode of the magnetron and controlling the output of the magnetron by adjusting current inputted to the microwave oven, comprising:
- a controller setting an initial input current, driving the magnetron at the initial input current greater than a rated current of the magnetron;
- and adjusting the initial input current, over a period of time, to less than the rated current to prevent overheating of the magnetron,
- wherein the period of time is set to be within a usable time of a power fuse.
