The pedestal 73 can freely slide on the bottom plate 53 a and the planar metal portion 37 a of the door 37.

  An object to be heated is placed in a heating chamber, and a heating (heater heating, high frequency heating etc) mode suitable for cooking is selected from the operation panel 57 and cooking is started. Since the mounting table 73 is also used for cooking by heating with a heater, it is made of metal and heat-resistant coated, and the leg portions 75 are provided at the four corners where the temperature is relatively low. Resin (PPS) is used for the legs 75 and the rails 90 in order to prevent sparks between the heating chamber walls 53 during high-frequency heating. Therefore, it can be used safely both when heating the heater and when heating the high frequency.

  When the set time is over, it is the same as when cooking is started. Since the mounting table 73 on which the object to be heated is pulled out to the vertical wall (stopper) 90c of the rails 90a and 90b, it cannot be pulled out any further. There is no worry of dropping things.

  The door 37 is set to a horizontal metal portion 37a having a width larger than the width on which the leg portion 75 of the heat-resistant resin of the mounting table 73 rides, and the door 37 is fixed by a stopper 39 in a substantially horizontal state. Since the bottom of the heating chamber and the door surface are substantially the same height, the vicinity of the side wall 53b on which the heat resistant resin leg 75 of the mounting table 73 slides is flat. The pedestal 73 can smoothly pull out on the bottom plate 53 a and the flat metal portion 37 a of the door 37.

  The position of the rail stopper 90c is about 1/3 or more so that the mounting table 73 is placed on the door, and even if the heating chamber is at a high temperature, the cooked food can be handled at a position where the heat is not felt. When cleaning, even if the mounting table 73 is set in the heating chamber, the deformed protrusions 75e of the rear legs 75C and 75d of the mounting table 73 (circular in section and partially flat) are between the protrusions of the rails 90a and 90b. Can be rotated, and a gap is provided between the rear leg portion 75c and the bottom plate 53a, so that the front of the mounting table 73 can be lifted up, and the heating chamber bottom plate 53a can be maintained. .

Moreover, when washing the mounting base 73, it is set as the structure which can take out the mounting base 73 independently. When it is pulled straight out to the door 37 side, the deformed projection 75e of the rear leg portions 75c and 75d of the mounting table 73 hits the vertical wall 90c on the opening side of the rail 90a and cannot be pulled out any further. When the mounting table 73 is lifted upward, the projections 75e having a deformed shape of the rear legs 75C and 75d (circular in section and partially flat) are rotated around the fulcrum, and are inclined from the vertical walls 90c of the rails 90a and 90b. The mounting table 73 can be taken out along the wall. This slanted wall also serves as a guide for mounting the mounting table. Thus, since the mounting table 73 can be detached independently, the mounting table 73 itself can be easily cleaned, but the heating chamber can be easily cleaned without any problems.

  As described above, in the present embodiment, the heating chamber has a vertically open door on the front surface, the bottom surface of the heating chamber and the height on the door surface are substantially the same height, A rail part is provided for moving, and a stopper part is provided for stopping the mounting table at a predetermined position when the mounting table is pulled out to the front, and the mounting table is detachable from the heating chamber. The mounting table 73 can freely slide on the flat metal portion 37a of the door 37 on the bottom plate 53a. Even when the heating chamber is at a high temperature, the door 37 is opened and the mounting table 73 is slid on the door 37. Can be pulled out.

  Further, the mounting table 73 can be taken out independently, and the mounting table 73 and the heating chamber can be easily cleaned. An easy-to-use cooking device with no protrusions on the door 37 can be provided.

  Furthermore, the rails 90a and 90b are fixed to the heating chamber by inserting the claws of the rails 90a and 90b into the holes of the heating chamber side plate 53b, and fixing the side plates 53b and the rear plate 53c by bending. Therefore, there is no need for extra parts, and it is possible to achieve an inexpensive, simple, reliable and strong fixing with a simple configuration. Moreover, the hole of the heating chamber side plate 53b is a small hole having a wavelength of 1 / 4λ or less of the wavelength used, and there is no concern about radio wave leakage from the hole.
