Description

[Detailed description of the invention] This invention relates to an improvement of an electric grater used for grating radish and the like.

In general, in this type of grater, a disc-shaped cutting blade that is rotationally driven by a motor is disposed in a cutting chamber shaped like a case, and the above-mentioned grater is mounted on the top wall of a surrounding wall surrounding the cutting chamber. A cylindrical insertion opening is formed corresponding to the cutting blade into which an object to be cut, such as a radish or carrot, is inserted, and the object to be cut inserted into this insertion opening is pressed against the upper surface of the cutting blade. However, it is configured to cut with a blade portion formed on its main surface.

By the way, conventionally, as shown in FIG.
Projection blade rows 71 (71., 71...
), each of the protruding blades 72 is made up of only triangular protruding blades as shown in FIG. On the surface, triangular grooves S as shown in FIGS. 8 and 9 are formed in the form of ripples, corresponding to each rotation locus l of the triangular protruding blade.

When this triangular groove S is formed, especially when cutting a workpiece M with a high moisture content such as a radish, each protruding blade is guided by the triangular groove S and slips, making it difficult to perform the cutting action.

For this reason, it has been proposed to shift the protruding blades in each row in the radial direction so that the triangular protruding blades do not follow the same trajectory, but even in this case, the above Even if the pitch of the rippled triangular grooves S becomes smaller, it is still difficult to reliably prevent the cutting action of the protruding blade from decreasing.

Therefore, this invention has a first row of protruding blades consisting of a plurality of triangular protruding blades and a second row of protruding blades consisting of a plurality of rectangular protruding blades.
By arranging the protruding blade rows radially on the main surface of the cutting blade body and alternating around the axis, and by positioning each rectangular protruding blade between each rotation locus of the triangular protruding blade, This allows each blade to effectively perform its cutting action on the surface of the workpiece without slipping.

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a drive unit case with an open top end, and a motor 3 fixed to a motor mounting base 2, a battery 4, etc. are housed inside.

5 is a driving gear fixed to the rotating shaft 6 of the motor 3, and this driving gear 5 is meshed with a driven gear 8 via a reduction gear 7.

Reference numeral 9 denotes a rotary drive shaft body to which the driven gear 8 is fixed and rotatably supported by a bearing body 10.11;
A disk-shaped rotary cutting blade 12 is attached to the tip 9a of the blade, and is rotated with high torque by the rotational force of the motor 3.

Reference numeral 13 denotes a container consisting of an annular saucer body 14 fitted over the open end 1a of the drive unit case 1, and a lid body 16 that opens and closes the opening 15 of the saucer body 14. A cutting chamber surrounding the blade body 12? The lid body 16, which is the top wall of the cutting chamber 17, has a cylindrical insertion opening 18 for inserting a workpiece M at an eccentric position relative to the cutting blade body 12. It is well-formed.

Reference numeral 19 denotes a pressing member that presses the cut object M inserted into the insertion opening 18 against the cutting blade body 12.

The main surface 12a of the cutting blade body 12 has a first protruding blade row 20 (20, 20...) as shown in FIG.
and second protruding blade rows 21 (21, 21...) are arranged radially and alternately around the axis.

Each protruding blade 22 of the first raised blade row 20 has a triangular protruding shape as shown in FIG. As shown in the figure, each of the rectangular protruding blades 23 is positioned between each rotation locus l of the triangular protruding blade 22 as shown in Fig. 2. There is.

In addition, in FIG. 1, 24 is a power switch. As is clear from the above structure, when the radish M inserted into the insertion port 18 is cut while being pressed against the main surface 12a of the cutting blade 12, the cut surface Ma of the radish M has the fifth As shown in the figure, a triangular groove S is formed by each of the triangular protruding blades 22 in the first protruding blade row 20, and subsequently each rectangular protruding blade 23 in the second protruding blade row 21 forms a triangular groove S. The stepped portion Sa between each triangular groove S is cut and flattened as shown in FIG. 6, and the next triangular protruding blade 22 is able to easily cut the stepped portion Sa, so that the cutting action is effectively maintained until the final stage of cutting.

As described above, this invention has a first protrusion row consisting of a plurality of triangular protrusion blades and a second protrusion blade row consisting of a plurality of rectangular protrusion blades on the main surface of the disc-shaped cutting blade body. By arranging the rectangular protruding blades radially and alternately and positioning the rectangular protruding blades between the respective rotation loci l of the triangular protruding blades, the protruding blades slide on the surface to be cut of the workpiece. It is possible to suppress this and improve the sharpness.
