The smoke generated in the heating chamber 5 is prevented from leaking to the outside. A part of the air blown toward the door 19 is blown toward the openings 52 and 54 formed in the door cover 46, and the pressure in the space between the door 19 and the door cover 46 is increased. Prevents smoke from leaking outside.

  In addition, air from the upper and lower outlets 36 and 36 of the cooling fan 25 is blown toward the circuit board 24 of the substrate holding plate 28 and is divided into multiple layers from the first floor to the third floor. Cools heat-generating parts such as diode bridges. Thereafter, the air passing through the circuit board 24 from the opening formed on the upper surface of the heating coil support 27 provided on the uppermost floor is directed to the opening of the board holding plate 28 on the side opposite to the cooling fan 25. The air is blown upward from the heating coil support 27, and cooling air flows from the heating coil 13 b to the heating coil 13 a and the housing 2, and is then discharged to the outside through the exhaust port 35.

  When the cooking of the object to be cooked is completed, when the handle 50 of the door 19 is gripped and pulled toward the front side, the movable rails of the rail units 16a and 16b slide with respect to the fixed rail, and the tray holder 64 and the tray 66. Since the grill net 68 is pulled out integrally, the object to be cooked can be easily taken out. In addition, by adopting the rail units 16a and 16b, even if the handle 50 is provided at the upper end portion of the door 19, the cooking object can be smoothly put in and out, and the upper end portion of the door 19 is made of the resin handle 50. By covering with, the safety or operability for the user is improved.

  As described above, the door 19 locked to the connection fitting 18 by the lock piece 56 is unlocked by pressing the pin 58 provided on the door 19, and after unlocking, the door 19 is lifted upward. Since the door 19 can be removed from the connection fitting 18, when the door 19 becomes dirty, the door 19 can be removed from the connection fitting 18 and cleaned appropriately. Further, when the door 19 is pulled out most from the heating chamber 5, the dimensions are set so that the rear end of the tray 66 is positioned on the near side of the opening surface. The attachment / detachment of the net 68, the attachment / detachment of the tray 66 to / from the tray holder 64, or the attachment / detachment of the tray holder 64 to / from the connection fitting 18 can be performed very easily, and each member can be appropriately cleaned as necessary.

  The door 19 is not necessarily attached to the connection fitting 18 in a detachable manner, and the door 19 may be fixed to the connection fitting 18. Moreover, although the connection metal fitting 18 demonstrated as what connects the front-end part of the movable rail of rail unit 16a, 16b mutually, the door 19 can also be attached to the front-end part of a movable rail, without providing the connection metal fitting 18. FIG. In this case, the tray holder 64 may be engaged with each of the pair of movable rails.

  Further, when the tray 66 is correctly attached to the tray holder 64, the hanging portion 82 formed at the front portion of the flange portion 80 enters between the tray positioning portions 74 on the near side of the tray holder 64. When the tray holder 64 is mounted in the reverse direction, the hanging portion 82 is set so as to ride on the rear end of the tray holder 64. As a result, the mounting position of the tray 66 is increased, and the door The tray 66 contacts the lower heater 7 before the door 19 closes the opening of the housing 2 so that the door 19 cannot close the opening of the housing 2.

  In addition, since the cooking of the to-be-cooked object using the heating coils 13a and 13b and the radial heater 14 is not the main point of this invention, the description is abbreviate | omitted.
