Abstract (en)
[origin: US4162381A] {PG,1 A microwave oven sensing system having a humidity sensor and a temperature sensor at an exit ventilation port of a microwave oven heating cavity to sense the exiting humidity and the air temperature of the microwave oven heating cavity. The humidity sensor and the temperature sensor are positioned to sense the {37 in-situ{38 {0 environmental conditions of the microwave oven heating cavity such as adjacent to and by the exterior of the exit ventilation port of the microwave oven heating cavity. The sensors connect to a programmable controller and input the sensed {37 in-situ{38 {0 environmental conditions of the microwave oven heating cavity to the programmable controller. {37 Characteristic humidity curves{38 {0 for microwave cooking of different types of foods are stored as algorithms in a memory of the programmable controlled and the programmable controller controls the microwave cooking in accordance with a selected algorithm for the sensed {37 in-situ{38 {0 environmental conditions. A numeric keyboard control panel inputs to the programmable controller the microwave cooking parameters and selects the microwave cooking algorithm. The programmable controller controls a microwave power source control circuit and an air exchange circuit according to the selected algorithm in the programmable controller. An additional humidity sensor may be positioned in a nonhostile environment within the frame structure of the microwave oven to provide a calibration reference for the humidity sensor positioned at the exit ventilation port of the microwave heating cavity.
