Abstract
A device and a method for compensating for temperature fluctuations for maintaining the warmth of a cooker having an inverter circuit, which has a system controller which obtains a final compensation data by processing a temperature compensation data outputted from a compensation temperature selection section and a present temperature detected by a temperature detecting section. The system controller outputs a driving signal to drive a bottom heater, a top heater, and a side heater of the cooker according to a calculated final compensation data.
Claims4
A device for compensating for temperature deviations to maintain warmth of a cooker having an inverter circuit, a bottom heater, a top heater, and a side heater, the device comprising:
- a temperature detecting means for detecting a present temperature;
- a compensation temperature selection means for selecting temperature compensation data in order to compensate for deviations of said present temperature detected from said temperature detecting means;
- and
- a system controller, coupled to said temperature detecting means and said compensation temperature selection means, and also coupled to said bottom heater, top heater and side heater, for controlling said bottom heater, said top heater, and said side heater according to a final compensation data calculated by comparing said temperature compensation data selected from said compensation temperature selection means with the present temperature detected from said temperature detecting means.
A method for compensation for temperature deviations in a cooker having an inverter circuit to maintain warmth of the cooker which has a bottom heater, a tope heater and a side heater, the method comprising the steps of:
- detecting said present temperature;
- selecting a temperature compensation data incrementally or decrementally in order to compensate for deviations of said present temperature;
- calculating a final compensation data from said present temperature and said selected temperature compensation data;
- and
- driving said bottom heater, said top heater, and said side heater according to said final compensation data calculated.
