By fitting the lid, the locked body that is interlocked with the cutter inside the container and is located outside the container can be engaged with the rotary locking body on the case body side. Therefore, according to such a configuration, the rotation of the drive motor is transmitted to the cutter via the rotary locking body and the locked body, and the food to be cooked in the container is crushed.

[0004]

However, while the flat portion is provided on the side surface of the bottom lid of the container, the flat portion that engages with the flat surface of the bottom lid is provided in the cylindrical portion to prevent the container from rotating. Therefore, it is necessary to match the fitting direction of the container with the cylindrical portion, which is troublesome. Further, although the outer peripheral surface of the bottom lid and the inner peripheral surface of the tubular portion are tapered, the bottom lid is thin and the taper angle cannot be increased, so that it is difficult to fit.

Therefore, according to the present invention, the container can be easily fitted into the tubular portion of the case body, and even if the container is fitted into the tubular portion in any orientation, the container is prevented from rotating with respect to the tubular portion. The object is to provide a cooker that can be used.

[0006]

To achieve this object, according to the present invention, a bottomed container fitting cylinder is provided on the upper wall of a case body, and a drive motor is built in a motor chamber of the case body. A rotary locking body that rotates around the axis of the container fitting cylinder in conjunction with the drive motor is disposed in the center of the bottom of the container fitting cylinder and fits into the container fitting cylinder. The fitted tubular part to be fitted is integrally provided at the lower end of the container, and has a cutter for crushing the material provided at the bottom part of the container, and is interlocked with this cutter and is connected to the container fitting tubular part. In a cooker in which a rotatable locking body that is coupled to the rotary locking body at the time of fitting the fitted cylindrical portion is rotatably held in the container fitting cylindrical portion, the fitted cylindrical portion is circumferentially arranged. The container fits with the locked protrusions protruding from the outer peripheral surface at an equal pitch. The tubular portion includes a small inner diameter tubular portion, a large inner diameter tubular portion continuously provided on an upper end of the small inner diameter tubular portion via an inclined step portion, and a plurality of locking projections protruding from an inner surface of the large inner diameter tubular portion, The large-inner-diameter tubular portion is a cooker that is formed sufficiently larger than the fitted tubular portion.

[0007]

With this structure, when the fitted tubular portion is easily loosely inserted into the large inner diameter tubular portion of the container fitting tubular portion, the fitted tubular portion is guided by the inclined step portion and the container is fitted. While fitting into the small inner diameter tubular portion of the tubular portion, one of the plurality of locked projections provided on the fitted tubular portion will engage with the locking projection of the container fitting tubular portion.
