<p>PURPOSE:To make it possible to dispose the cooking keys in an easily readable and operable manner by disposing only cooking selection keys of a high frequency in use on an operating panel and disposing cooking selection keys of a low frequency of use on a plane substantially flush with the glass of the door surface, and providing an air heat insulating layer between the cooking selection keys and a metallic frame. CONSTITUTION:Several cooking selection keys 3 of a high frequency in use are disposed on an operating panel with a sufficiently large size. On the other hand, since cooking selection keys 8 of a low frequency in use is disposed on the surface of an opening and closing door 5, the number of keys on the operating panel 1 is relatively reduced, and hence it is made possible to form an easily operable and easily observable arrangement. On the other hand, the cooking selection keys can be mounted on the plane flush with the glass 6 by a resin frame 9 without any surplus projection, and the temperature of a display part 8a can be lowered by the action of the air heat insulating layer 13 provided between the cooking selection layer 8 and the metallic frame 14. Furthermore, the size of each cooking selection key 8 is set to a value smaller than the width of the metallic frame 14 of the door 5 so that the cooking key does not protrude out of the metallic frame 14. Hence, the key 8 does not directly receive the radiant heat from the opening part 10a of the door 5 and the temperature can be lowered.</p> |
