Abstract
A microwave oven and a method of controlling the same, in which a cooking unit disposed in a cooking cavity is moved from an initial position to a cooking position. In the microwave oven, a magnetron is operated after heaters are moved to respective cooking positions where a rotating unit to move the heaters and the magnetron are operated. Accordingly, microwaves are radiated into the cooking cavity while the heaters are not being moved by the rotating unit, so a generation of heat and sparks resulting from a concentration of the microwaves into spaces between a moving unit including the rotating unit and the cooking unit and between the moving unit and a wall of the cooking cavity is preventable.
Claims35
A microwave oven with a cooking cavity therein and a cooking unit disposed in the cooking cavity, comprising:
- a magnetron that oscillates at a high frequency;
- a switching unit that switches an electrical connection between a power supply and the magnetron;
- a moving unit that moves the cooking unit from an initial position to a cooking position;
- and
- a control unit that controls the switching unit so that the magnetron is operated after the cooking unit is moved to the cooking position by the moving unit, where the magnetron and the moving unit are operated.
A method of controlling a microwave oven having a cooking cavity therein and a magnetron, comprising:
- operating the magnetron after moving a cooking unit to a cooking position by operating a moving unit, where the moving unit and the magnetron are operated, the moving unit being provided to move the cooking unit disposed in the cooking cavity from an initial position to the cooking position.
A microwave oven with a cooking cavity therein and a magnetron therein to oscillate at a high frequency and a cooking unit disposed in the cooking cavity, comprising:
- a switching unit to selectively switch power to the magnetron;
- a moving unit to move the cooking unit from a first position to a second position;
- and
- a control unit to control the switching unit to operate the magnetron after the cooking unit is moved to the second position when the magnetron and the moving unit are to be operated.
A microwave oven with a cooking cavity therein and a magnetron therein to oscillate at a high frequency and a cooking unit disposed in the cooking cavity, comprising:
- a power control unit to control an operation of the magnetron;
- a moving unit to move the cooking unit into a cooking position;
- and
- a control unit to control both the power control unit and the moving unit such that the magnetron is operated only after the cooking unit is moved to the cooking position.
A microwave oven with a cooking cavity therein and a magnetron therein to oscillate at a high frequency irradiating microwaves and a cooking unit disposed in the cooking cavity receiving the microwaves irradiated by the magnetron, comprising:
- a moving unit to move the cooking unit into a cooking position;
- and
- a control unit to control the moving unit and the magnetron such that the magnetron is operated only after the cooking unit is moved to the cooking position to prevent a concentration of the microwaves into spaces between the moving unit and the cooking unit and between the moving unit and a wall of the cooking cavity.
A method of controlling a microwave oven having a cooking cavity therein and a magnetron therein to oscillate at a high frequency irradiating microwaves and a cooking unit disposed in the cooking cavity receiving the microwaves irradiated by the magnetron, comprising:
