<p>A heating apparatus, or more particularly a heatingtime displaying device which is applicable for a heating apparatus with a programmable timer which is capable of controlling the sequence heating. The heating apparatus comprises heating sources such as magnetron and/or heater for heating a product to be heated, an output switching device for switching the output of said heating source into at least two steps, an output setting device for presetting the output specified by said output switching device, a timer device for controlling the heating time, a heating time setting device for presetting the heating time to said timer device, a memory for storing the output and heating time entered by said output setting device and said heat time setting device, a display device for displaying the entered output and heating time, and a main controller for controlling said heating source and said memory and all of said devices, and a stage recall device for recalling the heating pattern of a selected stage. The main controller has a function of calculating the total heating time of sequence heating so that either the total heating time or the heating time of each stage is indicated on the display device in accordance with a command from said stage recall device.</p> |
