By fitting the shaft portion 65 into the notch 55, the movable frame 5 is supported in the storage case 6 so as to be rotatable between the protruding position and the immersion position with the shaft portion 65 as a fulcrum. The operation panel 54 is exposed to the front of the front panel 12 by the rotation of the movable frame 5 to the protruding position, so that the operation panel 54 can be operated. It should be noted that the rear end portion of the upper plate portion 53 of the movable frame 5 is in contact with the upper side portion of the flange portion 64 of the storage case 6 from the rear so that the movable frame 5 projects forward from a predetermined projecting position. A stopper portion 53a is provided to prevent it.

  Further, as shown in FIG. 3, the biasing means 7 formed of a torsion coil spring that biases the movable frame 5 toward the protruding position side, and the movable frame 5 is locked at the retracted position and the movable frame 5 is pushed from the retracted position. Thus, a push-push type locking mechanism 8 that releases the locking is provided, and a speed reduction means 9 that decelerates the moving (turning) speed of the movable frame 5 by the biasing force of the biasing means 7.

  The locking means 8 includes a cam member 81 fixed to the storage case 6 and a lever member 82 pivotally supported on the side plate 52 on one side of the movable frame 5. An engaging pin 82 a is projected from the free end of the lever member 82. When the movable frame 5 is pushed from the protruding position to the retracted position, the engaging pin 82a engages with a locking groove portion of a heart-shaped cam groove (not shown) formed in the cam member 81, and the movable frame 5 When the movable frame 5 is pushed from the retracted position and the movable frame 5 is pushed from the retracted position, the engaging pin 82a is released from the locking groove and the movable frame 5 is unlocked. The movable frame 5 is rotated to the protruding position by the urging force.

  The decelerating means 9 has a longitudinal shape in the moving direction of the movable frame 5, that is, an arc-shaped rack 91 concentric with the shaft portion 65 that serves as a pivotal support point of the movable frame 5, and a pinion 921 and a pinion that mesh with the rack 91. And a damper 92 having a disk-shaped damper case 922 that pivotally supports 921. The damper 92 is configured to apply a rotational load to the pinion 921 with high-viscosity oil sealed in the damper case 922.

  Here, in the present embodiment, a through hole 62a having an arcuate hole edge concentric with the shaft portion 65 is formed in the side plate 62 on one side in the horizontal direction of the storage case 6, and the arc shape of the through hole 62a is formed. A rack 91 is formed at the hole edge. In addition, a damper 92 is provided on the side plate portion 52 on one side in the lateral direction of the movable frame 5 located inside the side plate portion 62 so as to be located at a portion that does not protrude from the storage case 6 even when the movable frame 5 protrudes. . According to this, when the movable frame 5 is rotated from the storage position to the protruding position by the urging force of the urging means 7, the pinion 921 moves while rotating along the rack 91, and the rotational load applied to the pinion 921. As a result, the rotational speed of the movable frame 5 is reduced.

  And in this embodiment, since the rack 91 which is one of the components of the speed reduction means 9 is provided in the storage case 6 in the container 1, the rack 91 can be seen even if the movable frame 5 is moved to the protruding position.

Further, the damper 92, which is another component of the speed reduction means, is provided on the side plate portion 52 of the movable frame 5 that does not protrude from the storage case 6 even when the movable frame 5 protrudes. There will be no appearance.

  It is also conceivable to provide a rack on the inner side surface of the side plate portion 62 without forming the through hole 62 a in the side plate portion 62 of the storage case 6. However, in this case, it is difficult to mold the rack integrally with the storage case 6 because of the mold removal of the molding die of the storage case 6. For this reason, it is necessary to fix a rack separate from the storage case 6 to the inner surface of the side plate portion 62 of the storage case 6, and the number of parts increases. On the other hand, if the rack 91 is formed at the hole edge portion of the through hole 62a provided in the side plate portion 62 of the storage case 6 as in the present embodiment, the mold can be opened in the lateral direction for forming the outer surface of the side plate portion 62. The rack 91 can be easily formed integrally with the storage case 6 simply by providing a rack forming part on the through hole forming convex part of the mold. Therefore, a separate rack from the storage case 6 is not required, and an increase in cost due to an increase in the number of parts can be avoided.

  By the way, when the front panel 12 is removed during the maintenance of the heating cooker, the storage case 6 is taken out together with the front panel 12 to the front of the body 1. In this case, if the damper 92 is detachably attached to the side plate portion 52 of the movable frame 5 through the through hole 62 a, the movable frame 5 is disengaged from the shaft portion 65 and the movable frame 5 is removed from the storage case 6. Therefore, the damper 92 can be exchanged and the maintainability is improved.

  Here, it is conceivable to fix the damper 92 to the side plate portion 52 of the movable frame 5 by screwing through the through-hole 62a, but this makes the screwing work troublesome. Therefore, in the present embodiment, the damper 92 can be detachably attached to the side plate portion 52 of the movable frame 5 through the through hole 62a and can be fixed without requiring screwing. Hereinafter, this point will be described in detail.

  In the present embodiment, the damper 92 has a bifurcated first protrusion 923 that protrudes from the peripheral surface portion of the damper case 922 opposite to the rack 91 with respect to the center thereof, and the first protrusion 923 is separated from the circumferential direction by a half circumference. A second protrusion 924 that protrudes from the peripheral surface portion of the damper case 922 is provided. Also, a first and second pair of pocket portions 521 and 522 that receive the first and second protrusions 923 and 924 from both sides in the lateral direction on the side plate portion 52 on the lateral side of the movable frame 5; A pin portion 523 that engages with the crotch portion of the first protrusion 923 and supports the damper 92 in a swingable manner is provided.

  Further, in the swinging direction of the damper 92 with the pin portion 523 as a fulcrum, the direction in which the second protrusion 924 is inserted into the second pocket portion 522 is the plus direction, and the direction in which the second protrusion 924 is detached from the second pocket portion 522. When the damper 92 is swung in the plus direction to a predetermined position (a position indicated by a solid line in FIG. 4) where the pinion 921 meshes with the rack on the side plate portion 52 on one side in the horizontal direction of the movable frame 5. A receiving surface portion 524 formed of a step surface inward in the lateral direction with which the circumferential surface portion in the plus direction of the damper case 922 abuts, and a claw at the tip end engaged with the circumferential surface portion in the minus direction of the damper case 922 at this predetermined position A tongue piece 525 having a portion 525a is provided. The tongue piece portion 525 is separated from the side plate portion 52 by slits on both sides in the width direction. Therefore, the tongue piece portion 525 can be bent elastically in the lateral direction which is the normal direction of the side plate portion 52. The first and second pocket portions 521 and 522, the pin portion 523, the receiving surface portion 524, and the tongue piece portion 525 are integrally formed with the side plate portion 52.

  According to the present embodiment, the tongue piece 525 is pushed inward in the lateral direction, and the engagement of the claw portion 525a with the peripheral surface portion in the negative direction of the damper case 922 is released, thereby swinging the damper 92 in the negative direction. Thus, the second protrusion 924 can be detached from the second pocket portion 522. Then, after swinging the damper 92 to a position where the second protrusion 924 does not interfere with the rack 91 (a position indicated by an imaginary line in FIG. 4), the first protrusion 923 is pulled out from the first pocket portion 521 and the pin portion 523 is removed. By releasing the engagement of the first protrusion 923, the damper 92 can be taken out through the through hole 62a. Further, the damper 92 can be attached to the side plate portion 52 of the movable frame 5 through the through-hole 62a in the opposite procedure.

  In this case, the damper 92 is sandwiched between the receiving surface portion 524 and the claw portion 525a of the tongue piece portion 525, and is positioned at the predetermined position with respect to the swinging direction, and the first and second protrusions 923 are disposed. , 934 are sandwiched between the first and second pocket portions 521 and 522 from both sides in the lateral direction, and are also positioned in the lateral direction, that is, the axial direction of the pinion 921. Therefore, the damper 92 is fixed to the side plate portion 52 of the movable frame 5 with the pinion 921 meshing with the rack 91. Therefore, it is not necessary to screw the damper 92, the attaching and detaching work of the damper 92 becomes easy, and the maintainability is further improved.
