Potential adjuster for maintaining freshness of food during thawing or cooking, including temperature sensor producing current supply controlling signals and frequency generator giving oscillating current

摘要

An electronic and frequency-controlled potential adjuster consists of a device for supplying an article with current; a sensor (14) for determining the temperature of the article; a temperature control unit (13) for receiving the signal from the sensor and sending signals (dependent on the temperature variation signals) to the current supply device; and a frequency generator for obtaining a periodically oscillating current.
