As shown in FIG. 5 and the like, the operation unit 3 includes a rotating body 4, a frame 5, a cover 6, a spring structure 7 and a conducting member 8. The operation unit 3 is incorporated into the cooker body 1 through a metal case 2 provided in a rectangular frame shape.

  As shown in FIG. 4 and the like, the rotary body 4 has a flat plate-like top plate portion 41 having an operation panel 300 on the upper surface, and a pair of side plate portions 42 extended downward from the left and right end edges of the top plate portion 41. Equipped with C-shaped connecting portions 43 are formed at lower end portions of the pair of side plate portions 42 (see FIG. 5 and the like).

  The top plate portion 41, the side plate portion 42, and the connecting portion 43 that constitute the rotating body 4 are integrally molded using a resin material.

  The frame 5 is assembled to the front of the cooker body 1 via a metal housing 2. The frame 5 is molded using a synthetic resin material so as to have a rectangular frame-like outer shape. As shown in FIG. 8 and the like, the frame 5 includes left and right side walls 51, and a bottom wall 52 connecting lower portions of the left and right side walls 51.

  At the front end of the bottom wall 52, a support shaft structure 53 for rotatably mounting the rotary body 4 and the cover 6 together and a projection structure 55 for mounting the spring structure 7 are formed (see FIG. 5). . The spring structure 7 is constituted by a so-called coil spring.

  The support shaft structure 53 is constituted by a support shaft 531 made of synthetic resin integrally molded at both end portions in the left-right direction of the front end portion of the bottom wall 52.

  The C-shaped connecting portion 43 of the rotating body 4 is rotatably fitted to each of the left and right support shafts 531 so that the rotating body 4 can rotate around the virtual center axis C1 extending to the left and right. Be supported. Similarly, the C-shaped connecting portion (not shown) of the cover 6 is rotatably fitted to each of the left and right support shafts 531 so that the cover 6 is rotatably supported around the central axis C1. Be done.

  The protrusion structure 55 is constituted by a pair of protrusions 551 made of synthetic resin integrally molded at a central portion in the left-right direction of the front end portion of the bottom wall 52. The pair of protrusions 551 protrudes in the direction approaching each other from the pair of restriction walls 571 provided with a distance between left and right. The pair of protrusions 551 are located on a straight line (on the central axis C1), and a distance is provided between the tip surfaces of each other.

  The spiral coil 70 included in the spring structure 7 is fitted in the pair of protrusions 551 so as to be rotatable around the central axis C1. The first arm 71 extended from one of the left and right ends of the coil 70 abuts on the upper surface of the bottom wall 52, and the second arm 72 extended from the other end of the coil 70 abuts on the rear surface of the cover portion The structure 7 applies a forward (opening direction) biasing force to the cover 6 and the rotating body 4 connected thereto. By this biasing force, the cover portion 6 and the rotating body 4 integrally rotate forward.

  The coil 70, the first arm 71 and the second arm 72 included in the spring structure 7 all have elasticity.

  In the heating cooker of one embodiment, although the projection structure 55 is configured by the pair of projections 551, the projection structure 55 is not limited to this, for example, the projection structure 55 is a projection extending in the left-right direction. It may be configured.

  In the spring structure 7, positional deviation in the left-right direction is prevented by the coil 70 coming into contact with the left and right restricting walls 571. That is, the restriction wall 571 at the position sandwiching the spring structure 7 restricts the position of the coil 70 in the left-right direction within a predetermined range (within the range where the pin-shaped conductive member 8 contacts the coil 70). Structure 57 is configured.

  In the front end portion of the bottom wall 52, an opening 58 penetrating in the vertical direction is formed long in the front and back direction in plan view. The front end of the opening 58 communicates with the space between the left and right restricting walls 571 (that is, the space in which the coil 70 is mounted).

  The first arm 71 is not straight as a whole, but is partially bent in a crank shape, and a portion of the first arm 71 is inserted into the opening 58 and protrudes downward of the bottom wall 52 through the opening 58. (See Figure 2). A portion of the first arm 71 which protrudes downward from the bottom wall 52 elastically contacts a metal lower frame portion which constitutes the lower portion of the housing 2.

  As shown in FIG. 5 and FIG. 6 etc., a vertical wall 54 protrudes upward from a central portion of the bottom wall 52 in the left-right direction. From the side of the vertical wall 54, a bowl-shaped horizontal wall 56 protrudes in the left-right direction. A space S1 is formed between the bottom wall 52 and the transverse wall 56 located above the bottom wall 52. The space S1 is open toward one side in the lateral direction (opposite to the side where the longitudinal wall 54 is located) and the front side. The space S1 is a space into which the tip end portion of the first arm 71 is inserted. As shown in FIG. 2 and the like, the bowl-shaped lateral wall 56 functions to restrict the upward movement of the first arm 71 when the tip end portion of the first arm 71 is located in the space S1.

  Next, the procedure for inserting the tip portion of the first arm 71 into the space S1 will be described.

  First, as shown in FIG. 9, the coil 70 is fitted to the projection structure 55 (the left and right projections 551). At this time, a portion of the first arm 71 protrudes downward through the opening 58, and the tip end portion of the first arm 71 is located on the lateral wall 56.

  In this state, the second arm 72 protruding upward is pushed backward (see arrow a1), whereby the entire spring structure 7 rotates backward around the central axis C1. Here, since the guide surface 561 is provided on the front end face of the lateral wall 56, the first arm 71 moves downward while elastically deforming the portion on the tip end side along the guide surface 561, from the lateral wall 56 By returning to the original shape at the stage of having moved downward (the stage of having passed the guide surface 561 downward), it moves into the space S1 (see arrow a2).

  The guide surface 561 is a surface inclined in its entirety such that the guide surface 561 is positioned more rearward in the left and right direction toward the portion farther from the vertical wall 54. The distal end portion of the first arm 71 slides on the guide surface 561 so as to slip into the space S1 so as to bypass the wedge-shaped lateral wall 56.

  Next, the cover 6 will be described.

  The cover 6 is attached to the rotating body 4 so as to cover and cover the front of the rotating body 4. When the rotating body 4 is located at the rearmost position in the rotation range (that is, when the rotating body 4 is in the closed position), the cover 6 constitutes the front face of the operation unit 3 in an upright posture.

  The cover 6 is mainly constituted by a front plate 61 made of synthetic resin, and a decorative panel 62 made of metal is mounted so as to hide the front of the front plate 61. While the front plate portion 61 is an insulating panel, the decorative panel 62 is a conductive panel.

  In the heating cooker of one embodiment, a conductive member 8 for static elimination is attached to the cover 6. As shown to FIG. 2, FIG. 5, the conduction | electrical_connection member 8 is a metal member formed in L shape. The conductive member 8 includes a pin-shaped first conductive body 81 provided to contact the rear surface of the decorative panel 62 and a pin-shaped second conductive body 82 provided to contact the coil 70 from above. , Integrally (see Figure 2). Although the conduction member 8 is configured by an L-shaped one member, it may be configured by a plurality of members.

  The cover 6 is formed with a groove 65 for receiving the conducting member 8. The groove portion 65 has a first groove portion 651 for housing the first conductive body 81 and a second groove portion 652 for housing the second conductive body 82 in one connection.

  The first groove portion 651 is formed between the front surface of the front plate portion 61 and the rear surface of the decorative panel 62. The second groove portion 652 is formed to penetrate the front plate portion 61 in the thickness direction.

  The first groove portion 651 is provided with a clearance which allows the first conductive body 81 accommodated therein to move up and down within a predetermined range. The first conductive body 81 contacts with the decorative panel 62 at any upper and lower positions within the predetermined range. The second groove portion 652 is provided with a clearance in which the second conductive body 82 accommodated therein can move up and down within a predetermined range. Conducting member 8 accommodated in groove 65 is movable up and down within a predetermined range, and the rear end portion of second conducting body 82 protrudes to a position where coil 70 of spring structure 7 contacts from above. It is configured to
