Abstract
A microwave oven with an electric device is provided in which the microwave oven includes an electric device control button and a control unit. The electric device control button drives the electric device by manipulation of a user and generates a power amount control signal to control power supplied to the electric device. The control unit controls the amount of power supplied to the electric device in response to the power amount control signal. The power amount control signal is a single pulse signal that is generated whenever the electric device control button is manipulated; and the amount of power supplied to the electric device is determined depending upon a number of occurrences of the single pulse signal.
Claims20
A microwave oven with an electric device, comprising:
- an electric device control button driving the electric device by manipulation of a user and generating a power amount control signal to control power supplied to the electric device;
- and
- a control unit controlling an amount of power supplied to the electric device in response to the power amount control signal.
A microwave oven having an electric device control button to generate a power amount control signal for driving an electric device to control power supplied to the electric device, comprising:
- a control unit controlling an amount of power supplied to the electric device in response to the power amount control signal, the control unit including a counter having an initial value increased in response to the power amount control signal and generating an overflow after counting from the initial value to a maximum value, and controls power to be supplied to the electric device when the overflow is generated.
A microwave oven having an electric device control button to generate a power amount control signal for driving an electric device to control power supplied to the electric device, comprising:
- a control unit controlling an amount of power supplied to the electric device in response to the power amount control signal;
- a counter to count based on a user input;
- and
- an interrupt generator generating a power supply interrupt based on the value in the counter, wherein an interrupt point is controllable within an interval between display interrupt points to generate the power supply interrupt.
A microwave oven having an electric device control button to generate a power amount control signal for driving an electric device to control power supplied to the electric device, comprising:
- an electric device control button producing a power control signal when operated;
- a register incrementing from an initial value to a maximum value based on each operation of the electric device control button and resetting to the initial value after reaching the maximum value;
- an overflow counter incrementing upon reset of the register;
- and
- an interrupt generator generating a power supply interrupt based on the value in the counter, wherein an interrupt point is controllable within an interval between display interrupt points to generate the power supply interrupt.
