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. The cutter is attached to a rotary shaft inserted into the container and the workpiece is rolled on the upper surface of the cutter to cut the workpiece, while the cutter is attached to the rotary shaft introduced into the container and the material is fed into the lid of the container. There is a type in which the workpiece is inserted through the mouth and pressed, and the cutter cuts the workpiece.

Input the workpiece from the latter material input port and press it.
As a type of cutter that cuts the workpiece,
The inventors put it on the top of the lid. In addition to integrally forming a charging tube with an opening, a first push rod is provided that can slide up and down within this charging port, and the inside of this first push rod is hollowed to form a small charging port. We have proposed an electric cooker in which a second push rod is slidably moved up and down in the mouth.

As shown in FIGS. 6 and 7, this electric cooker has an upper opening of a container (not shown) and a protrusion of a main body (not shown) in which a switch (not shown) is provided. (not shown)
A charging tube 62, which serves as a charging port 61, is integrally formed in the lid 60 that covers the charging port 61, and a lid portion 60a that covers the upper end opening and the protrusion of the charging port 61 is a charging tube lid. (not shown).

On the other hand, the cutter 63 is connected to a motor (
A plate-shaped knob 66 that can be gripped with fingers is integrally provided on the upper surface of the cutter 63 and protrudes from the cutter shaft 64. At the same time, a one-step portion 67 is formed at the lower end of the knob portion 66 . This cutter 63 has a rotary shaft 65 introduced inside a cutter shaft 64 and is arranged at the upper end of the container, and a knob 66 is located inside the input cylinder 62, and a semicircular shape is formed around the cutter 63. The diametrical wall portions 62a of the input tube 62 are located opposite to each other.

With such a configuration, when the rotary shaft 65 is driven by the motor and the cutter 63 is rotated.

The workpiece in the input cylinder 62 is cut by the blade 63a of the cutter 63 and falls into the container.

[Problems to be Solved by the Invention] When the cutter 63 rotates, the knob portion 66 is formed in a plate shape, and the stepped portion 6 from the top surface of the cutter 63
When the height H of cutter 7 is low, the workpiece in the container is
From the gap 68 between the upper surface of 3 and the lower surface of the charging tube 62,
As shown in , it is wrapped around the knob part 66 and the arrow B
As shown in FIG. 2, there was a problem in that the cutting material was thrown outward from the charging tube 62 through the opening 69 of the wall 62a of the charging tube 62, and fell into the container without being cut.

[Means for Solving the Problems] The present invention provides a five-disc cutter with a blade on the top surface, and a knob portion protruding toward the top surface of the cutter at the center of rotation of the cutter. A step is provided at the lower end of the knob, and the height of this step from the top of the cutter is approximately the same as the vertical gap between the lower edge of the input barrel and the top of the cutter, which are located opposite to each other around the knob. By setting the dimensions, it is possible to prevent the workpieces in the container from being caught around the knob and being thrown outward from the charging tube.

[Operation] After the upper end opening of the container is closed with a lid, the workpiece is put into the charging port of the charging cylinder provided in the lid. The switch is turned on, the motor is driven, the shaft rotates once, and the cutter rotates. When the push rod presses the workpiece on the cutter, the workpiece is cut by the cutter blade.
It is stored at the bottom of the container.

Even if the knob rotates during cutting, the workpiece inside the container is blocked by the first step and will not be wrapped around the knob, and therefore will not be blown outward from the input tube. .

To remove the cutter from the rotating shaft after cooking, hold the knob with your fingers and pull it upwards.At this time, your fingertips are in contact with the step at a higher position than the blade edge, so the cutter cannot be removed. There is no chance of damage due to the cutting edge pointing towards the center of the blade.
