Abstract
A method for controlling a heating cooking apparatus, in which an operation of a heating unit is appropriately controlled according to presence/absence or kinds of a load applied to a plate. When no load is applied to the plate, the duty cycle of a heat source is reduced, thereby preventing unnecessary operation of the heat source. Accordingly, power consumption is reduced. On the other hand, when a load is applied to the plate, the duty cycle of the heat source is increased. Speedy cooking may be possible with this control method.
Claims7
A method for operating a heating cooking apparatus, comprising:
- sensing at least one variable using a sensor that is indicative of whether at least one of a load, an absence of load, and a kind of load is present on a plate of the heating cooking apparatus;
- and
- controlling a duty cycle of power supplied to a heating source based on the variable sensed by the sensor,
- wherein a power on portion of duty cycle of power supplied to the heating source when the plate has a load is larger than the power on portion of duty cycle of power supplied to the heater source when the plate has no load,
- wherein heat of the plate is transferred to the sensor, and the sensor senses the heat from the plate and the heating source,
- wherein the heating source is turned off at least once prior to the sensed temperature reaching the first reference temperature and then the heating source is turned on until the sensed temperature reaches the first reference temperature.
