Description

  According to the present invention, a storage case provided in a front portion of a heating cooker such as a gas stove or the like is provided with a projecting position projecting forward of a front surface of the housing with a pivot provided at a lower front end of the storage case as a fulcrum The control panel is fixed to the upper surface of the movable frame, and the control panel is fixed to the projecting position of the movable frame. The present invention relates to an operating device for a heating cooker that is exposed in front of the front.

  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 mounted, and a front plate portion which can be opened and closed. Then, a battery case long in the front-rear direction is installed in a part of the lower part of the storage case in the lateral direction, and the battery can be taken in and out of the battery case with the front plate portion of the movable frame opened.

  In addition, conventionally, in such an operation device, the biasing means is constituted by a torsion coil spring having a coil portion located on the side of the battery case near the lower front of the storage case, and both ends of the coil portion are extended. 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 of the movable frame (see, for example, Patent Document 1). In this case, the storage case is provided with a guide plate for sandwiching the coil portion of the torsion coil spring from both sides in the lateral direction, and the coil portion is inclined while the movable frame is moving up and down, and the arm portions at both ends of the torsion coil spring are from the storage case or the movable frame I try not to let go.

  By the way, recently, with the high functionalization of the heating cooker, the enlargement of the control panel is required. Here, since the width of the control panel is limited, in order to increase the size of the control panel, it is necessary to increase the depth dimension of the control panel. However, when the depth dimension of the operation panel is increased, the position of the rear end of the operation panel at the immersive position of the movable frame becomes considerably lower, and the rear end of the operation panel interferes with the battery case. In this case, if the battery case long in the lateral direction is installed in the lower front part of the storage case, interference of the rear end of the operation panel with the battery case can be avoided.

  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 can not be disposed at the lower front portion of the storage case. Therefore, it is considered that the direction of the torsion coil spring is changed to position the coil portion behind the movable frame. In this case, it is impossible to provide the storage case with a guide plate sandwiching 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 be inclined during the movement of the movable frame, the arm portions at both ends of the torsion coil spring may be detached from the storage case or the movable frame, and the movable frame may not be biased toward the projecting position.
