Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an electric cooker for shredding workpieces such as fruits and vegetables.

[Prior Art] Conventionally, as a cooking device for cutting or shredding workpieces such as fruits and vegetables, a container is attached to the top surface of the main body in which a motor is arranged, and the cooking device is introduced into the container. One type has a cutter attached to a rotating shaft inserted into the container and cuts the workpiece while rolling it on the "-" surface of the cutter, and the other has a cutter attached to a rotating shaft introduced into the container and is installed in four parts of the container. There is a method in which the workpiece is inputted from J and pressed while being pressed to cut the workpiece with a cutter.

Input the material to be added from the latter material input port and press it.
As a type of cutter that cuts the workpiece,
As shown in FIG. 8, the inventors et al.
A substantially semicircular charging cylinder 73 having a size approximately half of the lid 72 is integrally formed on the upper surface of a lid 72 that covers the upper end opening of the container 71, which is detachably attached. A charging lower 4 is provided inside, and the opening at the upper end of the charging lower 4 is covered with a charging cylinder lid 75. Furthermore, the charging cylinder lid 7
5 is provided with a first push rod 76 that is slidably movable up and down within the input lower 4, and the inside of the first push rod 76 is hollowed out to form a small input lower 7. The second push rod 78 is slidably moved up and down. I suggested the lio cooker.

In this electric cooker, the fitting part 72a where the lid 72 comes into contact with the inner wall surface of the upper end of the container 71 is formed in a substantially semicircular shape corresponding to the part where the charging cylinder 73 is not formed. A plurality of ribs 79 are protruded from the outer wall surface of the charging tube 73 at the approximately semicircular portion of the rest where the container 71 and the container 71 fit together. The container 71 and the four bodies 72 are positioned in contact with each other in the horizontal direction.

With such a configuration, after the cutter 81 is fixed to the rotating shaft 80 protruding into the container 71, when the upper end opening of the container 71 is closed by the lid 72, the rib 79 is attached to the inner wall surface of the upper end of the container 71. The lid body 72 and the container 71 are positioned in the horizontal direction by contacting each other.

Next, when the rotary shaft 80 is driven by the motor 82 and the cutter 81 is rotated, the workpiece in the input tube 73 is cut by the blade 81a of the cutter 81, and the workpiece is cut by the slit provided on the front surface of the blade 81a (Fig. (not shown) into the container 71.

After cooking, as shown in FIG. 9, after storing the cutter 81 in the storage case 83, the opening of the storage case 83 is covered with the lid 72. At this time, the ribs 79 are attached to the storage case 8.
3, so if the lid 72 is simply placed on the storage case 83, the loading cylinder 73 side is heavy, so the lid 72 will be tilted and unstable. The upper end opening of the charging cylinder 73 provided on the lid body 72 is covered with a charging cylinder lid 75, and the hook part 85 of the storage case 83 fixes the lid body 72 and the charging cylinder lid 75.

Further, as shown in FIG. 10, the fitting part 72a between the container 71 and the lid 72 is extended to the periphery of the charging tube 73, so that the lid 7
2, the side wall 72b on the side of the charging cylinder 73 is formed, and the fitting part 72
When the entire circumference of the upper end opening of the container 71 is formed by the lower end of the side wall 72b and the lower end of the side wall 72b, two wall surfaces, the side wall 73a of the charging cylinder 73 and the side wall 72b of the lid body 72, are formed with a gap 84 interposed therebetween. be done.

Alternatively, the side wall 72b of the lid 72 on the charging cylinder 73 side may be integrally formed with the side wall 73a of the charging cylinder 73 to be thick.

[Problems to be Solved by the Invention] When covering the upper end opening of the container 71 with the four bodies 72, the ribs 79 simply come into contact with the inner wall surface of the upper end of the container 71. The ribs 79 are used for positioning in the horizontal direction, but positioning in the vertical direction is not possible.

Moreover, as shown in FIG. 1θ, the fitting portion 72a and the side wall 72b
Among those formed in series around the entire circumference of the lid body 72, like the former, two wall surfaces, the side wall 72b of the lid body 72 and the side wall 73a of the charging tube 73, are connected with a gap 84 therebetween. The molded type has a narrow gap 84, so dirt tends to accumulate there and is difficult to clean, and the latter type, which is formed thicker, has the problem of poor moldability with synthetic resin. there were.

[Means for Solving the Problems] The present invention has a substantially semicircular injection tube with a radial center portion,
In addition to positioning the center of rotation of the cutter, the distance from the center of rotation of the cutter to the inner wall surface of the charging tube is set smaller than the radius of this cutter, and furthermore, the outer wall surface of the charging tube is positioned horizontally with respect to the container. In addition to providing a rib for positioning, at least one positioning rib is provided with a step at the lower end of the rib that engages with the edge of the container to position the container in the vertical direction. directional and vertical positioning.

[Operation] When the top opening of the container is closed with the lid, the stepped portion of the rib comes into contact with the top inner wall surface and edge of the container, thereby positioning the container and the lid in the horizontal and vertical directions. .

Next, the workpiece is loaded into the input tube through the input port provided in the lid. When the switch is turned on and the motor is driven, the shaft rotates once and the cutter rotates, so when the push rod presses the workpiece on the cutter, the workpiece is cut by the cutter blade, and the lower part of the container is cut. will be stored in.

Furthermore, since the distance from the center of rotation of the cutter to the arc-shaped inner wall surface of the charging tube is set smaller than the radius of the cutter, the workpiece on the upper surface of the cutter is placed in the cutter, and the gap between the lower edge of the charging tube and the cutter is smaller than the radius of the cutter.
