There is one that is designed to be engaged with a member.

In such a cooker, a plurality of clamp claws that are linked to one operation knob are provided on the main body, and a claw engagement hole corresponding to each clamp claw is provided in the cooking case, and the clamp claw is inserted into the claw engagement hole. It is conceivable that the cooking case is held and fixed on the main body by engaging the cooking case.

When such a plurality of clamp claws are linked to one operating knob, a link mechanism can usually be used.

(Problem to be solved by the invention) However, since the link mechanism requires a large number of parts, storing this link mechanism within the main body requires a large space, and the main body tends to become large. There is a problem in that the mounting positions of other parts are also subject to restrictions. Another problem is that it takes time and effort to assemble the link mechanism.

Therefore, the purpose of this invention is to provide a clamping device for a cooker that can minimize the space inside the main body, has a simple structure, can interlock multiple clamp members, and is relatively easy to assemble. It is.

(Means for Solving the Problem) In order to achieve this object, this invention provides a cooking device in which a cooking case is disposed on the upper part of a main body whose side wall is formed into a cylindrical shape, and an opening for a claw is provided at the upper part of the side wall. A plurality of clamp members are formed at intervals in the circumferential direction, a claw engaging hole is formed in a portion that covers the claw opening of the cooking case, and a clamp claw portion is disposed in each of the claw openings. is disposed in the main body, and the clamp member is biased outward by a spring, so that the clamp claw portion is engaged with the claw engagement hole through the claw opening, and a circular shape extending in the circumferential direction An arc-shaped slide plate is supported so as to be movable in the circumferential direction along the inner surface of the side wall, and an operating knob provided on the slide plate is inserted into a knob opening provided in the side wall so as to be movable in the circumferential direction of the side wall. The clamping device for a cooking appliance is provided with a cam protrusion on the slide plate that projects outwardly and moves the clamp member inward at the same time when the slide plate is moved in the circumferential direction.

Further, the clamp member is provided with an opposing portion facing the inner surface of the side wall, and an engaging recess that opens toward the inner surface of the side wall and the circumferential direction is provided in the opposing portion, and a gap between the engaging recess and the inner surface of the side wall is provided. It is preferable to hold the slide plate slidably in the circumferential direction.

Furthermore, by interposing a clamp spring between the slide plate and the main body so as to bias the slide plate in a direction in which the engagement between the cam protrusion and the clamp member is released, the clamp claw portion may be constantly urged outward by the clamp spring.

(Function) According to such a configuration, by operating the clamp knob in the circumferential direction of the main body side wall, the slide plate is slid in the circumferential direction along the inner surface of the side wall. With this operation, the plurality of cam protrusions on the slide plate are simultaneously engaged with or disengaged from each clamp member. When each cam protrusion engages with each clamp member, the clamp claw portion is pulled out from the claw engagement hole of the cooking case, making it possible to remove the cooking case from the main body. On the other hand, when each cam protrusion disengages from each clamp member, the clamp claw portion is engaged with the claw engagement hole of the cooking case, and the cooking case is fixed to the main body.
