Description

  The present invention provides a storage case provided at the front part of a cooking stove such as a gas stove, with a protruding position protruding forward from the front of the container, with a support shaft provided at the lower front end of the storage case as a fulcrum. A movable frame that is swingably supported at an immersive position stored in the storage case is provided. An operation panel is fixed to the upper surface of the movable frame, and the control panel is moved by swinging the movable frame to the protruding position. The present invention relates to an operation device for a cooking device that is exposed in front of a front surface.

  In this type of operation device, the movable frame generally has side plate portions on both sides in the lateral direction, an upper plate portion on which the operation panel is placed, and a front plate portion that can be freely opened and closed. A battery case that is long in the front-rear direction is installed at a portion of the lower part of the storage case in the lateral direction so that the battery can be taken in and out with the front plate portion of the movable frame open.

  Conventionally, in such an operating device, the urging means is constituted by a torsion coil spring having a coil portion located on the side portion of the battery case near the lower front of the storage case, and at both ends extended from the coil portion. There is also known one in which the arm portion is locked to the lower rear portion of the storage case and the upper plate portion rear portion of the movable frame (for example, see Patent Document 1). In this case, a guide plate that sandwiches the coil portion of the torsion coil spring from both sides in the lateral direction is provided in the storage case, the coil portion is tilted during the movement of the movable frame, and the arm portions at both ends of the torsion coil spring are separated from the storage case and the movable frame. I try not to come off.

  By the way, recently, with an increase in functionality of a heating cooker, an increase in the size of an operation panel is required. Here, since the width of the operation panel is limited, in order to increase the size of the operation panel, it is necessary to increase the depth dimension of the operation panel. However, when the depth dimension of the operation panel is increased, the position of the rear end of the operation panel at the immersion position of the movable frame is considerably lowered, and the rear end of the operation panel interferes with the battery case. In this case, it is possible to avoid the rear end of the operation panel from interfering with the battery case by installing a battery case that is long in the lateral direction at the lower front portion of the storage case.

  However, in this case, the lower front portion of the storage case is occupied by the battery case, and the coil portion of the torsion coil spring cannot be disposed in the lower front portion of the storage case. Therefore, it is conceivable to change the direction of the torsion coil spring so that the coil portion is positioned behind the movable frame. In this case, it is impossible to provide the storage case with a guide plate that sandwiches the coil portion from both sides in the lateral direction because the movable frame interferes with the guide plate. As a result, the coil portion may tilt during the moving operation of the movable frame, the arm portions at both ends of the torsion coil spring may come off from the storage case or the movable frame, and the movable frame may not be biased toward the protruding position.
