Claims

[Scope of utility model registration request]

An operating means connected to the gas on-off valve that controls the gas supply/cutoff and the supply flow rate in a heating cooker that uses combustion gas, and is operated by pressing and releasing the operating knob that is locked so that it cannot rotate. The operating mechanism has a rotatable operating knob that protrudes from the front of the panel, and has a valve stem insertion hole that can transmit rotational motion by inserting and engaging the valve stem of the gas on-off valve, and a heart-shaped circulating feed pawl. A lock piece having a stop groove is formed, and the lock piece is slidable in the axial direction on the axial center of the operation piece attached to the rear surface of the operation knob, and is capable of transmitting rotational motion. , the lock pin is inserted and engaged with an expanding coil spring interposed therebetween, and the locking portion at the tip of the lock pin fixed to the operation piece is engaged with the circulation pawl locking groove to connect the operation piece and the lock piece. Furthermore, a sliding protrusion is formed to protrude outward from the rear end of the outer periphery of the operating piece, and the guide member positioned on the outside of the operating piece includes a straight guide that can guide the sliding protrusion. The part is formed parallel to the axis of the operation piece, and a stop wall is provided at the tip position of the part to which the sliding protrusion comes into contact, and the position with this stop wall is the starting end, and
A circular guide portion closed at a position at a set angle from the starting end is provided on a circular line concentric with the axis of the operating piece, and the starting end and the tip of the straight guide portion are formed in communication and engaged. The guide member is configured such that the sliding protrusion can prevent any movement other than back and forth movement in the straight guide part and circular movement in the circular guide part, and can be fixed to a part of the gas on-off valve. An operating device for a heating cooker.
