Abstract
A microwave oven and a method of controlling the same. The microwave oven is capable of using a plurality of input powers with different frequencies. The microwave oven includes input power sources, an interrupt generation unit and a control unit. The interrupt generation unit generates interrupt signals with different periods according to the frequencies of the input powers. The control unit cumulatively counts pulses generated on the basis of the interrupt signals outputted from the interrupt generation unit, compares the cumulatively counted value with a reference value, and discriminates the frequencies of the input powers depending on the number of instances where the cumulatively counted value is equal to or greater than the reference value.
Claims26
A microwave oven useable with a plurality of input powers with different frequencies, comprising:
- input power sources which transmit the corresponding input powers;
- an interrupt generation unit which generates interrupt signals having different periods according to the different frequencies of the input powers;
- and
- a control unit which cumulatively counts pulses generated on a basis of the interrupt signals outputted from the interrupt generation unit, compares a cumulatively counted value with a reference value, and discriminates the different frequencies of the input powers depending on a number of times where the cumulatively counted value is equal to or greater than the reference value.
A method of controlling a microwave oven useable with a plurality of input powers with different frequencies, the method comprising:
- generating interrupt signals having different periods according to the different frequencies of the input powers;
- cumulatively counting pulses generated on a basis of the interrupt signals;
- comparing a cumulatively counted value with a reference value;
- cumulatively counting a number of times where the cumulatively counted value is equal to or greater than the reference value;
- and
- determining the different frequencies of the input powers depending on the number of times accumulated.
