BAKING CABINET WITH PROGRAM TEMPERATURE CONTROL Russian patent published in 1996 - IPC

FIELD: baking equipment. SUBSTANCE: cabinet has framework accommodating heat-insulated working chamber with electric heaters and temperature-sensitive elements, and heating control unit including a data input unit, analog-to-digital converters and program temperature control unit, indication unit and power amplifier. Heating law and final temperature are preset by data-input unit by parameters of piece-linear approximation of heating rate curve. Transition to next step A is initiated by comparison member of program temperature control unit after comparison of temperature and time codes preset by data-input unit, and coming from temperature-sensitive element through analog-to-digital converter. EFFECT: improved dynamic characteristics of heating process and extended field of device application. 2 cl, 3 dwg
