<p>A heating apparatus, or more particularly a heating-time displaying means (4) which is applicable for a heating apparatus with a programmable timer which is capable of controlling the sequence heating. The heating apparatus comprises a heating source (17) such as magnetron and/or heater for heating a product to be heated, output switching means (15) for switching the output of said heating source (17) into at least two steps, output setting means (2) for presetting the output specified by said output switching means (15), timer means for controlling the heating time, heating time setting means (3, 19) for presetting the heating time to said timer means, a memory for storing the output and heating time entered by said output setting means (2) and said heat time setting means (3, 19), display means (4) for displaying the entered output and heating time, and a main controller (11) for controlling said heating source and said memory and all of said means, and stage recall means (8,2) for recalling the heating pattern of a selected stage. The main controller (11) 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 means (4) in accordance with a command from said stage recall means (8, 2).</p> |
