Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cutter that is selectively attached to the rotational drive shaft of a food processor and used for grating radish and the like.

C. Prior Art) Figure 5 shows a food processor equipped with a lower cutter. In the figure, reference numeral 1 denotes a main body case having a container mounting table 1a, and a plurality of tubes integrally projecting downward from the table 1a, etc. (only one is shown in FIG. 5).
A support plate 4 is horizontally attached to the screw receiver over the lower end of the boss 2 by means of screws 3 which are screwed into the screw receiver. It should be noted that rubber plates 5 for vibration isolation are interposed at the tightening portions of the screws 3, respectively. The support plate 4 is disposed within the main body case 1, and a lower end portion of a vertically erected rotary shaft 6 is rotatably supported on a portion of the support plate 4 via a bearing 7. Furthermore, the main body case 1 has a built-in motor 8 supported by a support plate 4, and a driven large gear 10 that meshes with a small drive gear 9 fixed to a rotating shaft 8a of the motor 8. .

A drive rotating shaft 11 having a tapered tip is integrally provided on the upper surface of the central portion of the large driven gear 10 . This drive rotation shaft 1
1 is fitted onto the rotating shaft 6 and rotated together with the rotating shaft 6. And the drive rotation shaft 11
The upper part of the container mounting table 1a passes through the approximate center of the container mounting table 1a. Further, a cover 12 is attached to the upper surface of the container mounting table portion 1a, and the cover 12 integrally has a cylindrical portion 12a approximately in the center thereof through which the drive rotation shaft 11 passes.

In addition, 13 in FIG. 5 is a disk attached to the outer periphery of the drive rotation shaft 11, and is used to catch moisture, etc. that runs down the outer circumference of the drive rotation shaft 11 and scatter it around. It is.

A container 14 made of transparent synthetic resin or the like and having an open top is removably placed on the cover 12 covering the container mounting table 1a. A handle 14a is integrally provided on the outer surface of the cylindrical peripheral wall of the container 14, and the cylindrical portion 12 is provided approximately at the center of the bottom wall of the container 14.
A fitting cylindrical portion 14b that is removably fitted to the outer surface of a is provided. The fitting cylindrical portion 14a is longer than the cylindrical portion 12a, and the drive rotary wheel 11 passes through it.

A lid 15 that closes the upper opening of the container 14 is removably fitted. This lid 15 has an extension part 15a that fits into the upright part 1b located above the container mounting base part 1a of the main body case 1, and the inner surface of this extension part 15 has a downward switch pressing convex part. 16 are integrally provided in a protruding manner. When the lid 15 is placed on the raised portion 1b, this convex portion 16
It closes a normally open safety switch 17 installed inside. The safety switch 17 is provided separately from a main switch (not shown), and the motor 8 is operated when both switches are closed.

The driving rotation shaft 11 is provided with the respective cylindrical portions 12a, 1.
A cutter shaft 18 made of synthetic resin is loosely inserted into the inside of the cutter shaft 4b and is removably fitted therein, and this shaft 18 is adapted to be rotated together with the drive rotation shaft 11. Further, in the container 14, a lowering cutter 19 is housed, which is detachably supported by the support portion 18a of the cutter shaft 18 and rotated together with the cutter shaft 18.

The lowering cutter 19 is formed by screwing a ring-shaped cutter plate 19b to a supported member 19a made of synthetic resin that is engaged with the support portion 18a. The cutter plate 19b is made of metal and has many cutting and raising blades on its surface. An annular gap 20 is formed between the outer peripheral surface of the drop cutter 19 and the inner peripheral surface of the peripheral wall of the container 14.

In order to grate radish or the like using the food processor configured as described above with the cutter 19 attached, first, the material to be ground is cut into an appropriate size and put into the upper space of the container 14 with the cutter 19 as the bottom. After that, close the lid, and then operate the motor 8. Then, each gear 9
．． 10, the rotating shafts 6, 11 and the cutter shaft 18 are rotated together, and the lowering cutter 19 is also rotated.

Therefore, the material to be unloaded, which is not pressed against the lowering cutter 19 and can move freely in the upper space inside the container 14, comes into contact with the cutting and raising blade of the cutter plate 19b and is lowered, and at the same time, it rolls and is thrown away, and the material is lowered into the container 14. The cutter plate 1 collides with the inner circumferential surface of the cutter plate 1 and the inner surface of the lid 15 and falls.
It comes into contact with the cutting and raising blade 9b and is lowered. By repeating this process, the material to be unloaded is gradually grated, and the grated material is transferred to the unloading cutter 19 and the container 14.
It is discharged downward from the gap 20 between the container 14 and stored in the lower space of the container 14. That is, the material to be unloaded is automatically grated as described above.

Details of the down cutter 19 conventionally used in such a food processor are shown in FIGS. 6 to 8. Reference numeral 21 in these figures indicates a cutting and raising blade formed by cutting and raising the surface of the cutter plate 19b, and a large number of cutting and raising blades 21 form a set of blade rows A. A large number of blade rows A are provided at predetermined intervals. Note that 22 indicates a groove formed in the cutter plate 19b by being cut and raised. A large number of cutting and raising blades 21 forming each blade row A are sharpened from a direction perpendicular to the blade row A. Therefore, each cutting and raising blade 21
The cut and raised surface 23 is provided along the blade row A when viewed from the plane direction of the lowering cutter 19, and the lowering cutter 1
It faces toward the outer circumference of 9. Note that the arrow in FIG. 6 indicates the direction of rotation of the lowering cutter 19.

[Problem that the invention seeks to solve]

By the way, according to the structure of the cut-and-raised blade 21 as described above, since the cut-and-raised surface 23 is provided along the blade row A, the material to be lowered is placed on each edge inside and outside of the cut-and-raised surface 23. At the same time, the blades are cut simultaneously by the lower cutter 19 and are easily moved toward the inner circumferential surface of the container 14 along the blade row A by the centrifugal force caused by the rotation of the lowering cutter 19. Therefore, there is a problem that the speed at which the material flies out toward the inner circumferential surface of the container 14 is high, and there are few opportunities for contact with the blade row A, resulting in poor cutting efficiency. A relatively large material to be grated tends to bite into and adhere to the grated material layer. The material to be lowered that has adhered to the inner circumferential surface of the container 14 in this way is then moved along the inner surface of the container 14 into the gap 2.
Conventionally, there was a problem in that a large amount of material adhered to the inner circumferential surface of the container 14 because this hindered the movement of the material to be discharged from the container 14.

Means for Solving Problem C] The present invention solves the above-mentioned conventional problems by directing the cut-and-raised surface of each cut-and-raised blade forming the blade row toward the rotation center of the lowering cutter. It is.

(Function) The cutting and raising blade of the lowering cutter equipped with the above solution is provided with its cutting and raising surface facing toward the rotation center of the lowering cutter. It digs into and performs cutting. Therefore, the cut and raised surface can suppress the movement of the material to be lowered in the outer circumferential direction of the lowering cutter due to centrifugal force along the blade row, and the cut and raised surface allows the material to be lowered to be lowered toward the rotation center of the cutter. (inner circumferential side). Thereby, it is possible to secure many opportunities to unload the material, and to reduce the speed at which the material flies out of the cutter.

〔Example〕

The fourth factor from FIG. 1 shows an embodiment of the present invention, and numeral 31 in FIG. 1 indicates the entire cutter, and this cutter 31 is selected for the food processor already described with reference to FIG. It is installed and used. This lowering cutter 31 has a supported member 34 made of synthetic resin attached to the inner circumference of a metal ring-shaped cutter plate 33, which has a plurality of blade rows a consisting of a large number of cutting and raising blades 32 on its surface, and a supported member 34 made of synthetic resin with screws 3.
5 and is fixedly formed. The supported member 34 is removably engaged with the support portion of the cutter shaft shown in FIG. Of course, it is supported so as to rotate.

As shown in detail in FIGS. 2 to 4, each cutting and raising blade 32 has a cutting edge that is formed by gouging out the front side of the cutter plate 33. A triangular pyramid-shaped cut groove 36 is provided in each of the cutting and raising blades 32 so as to be continuous with the root.

Each cutting and raising blade 32 has its cutting and raising surface 37
The blade is attached toward the center of rotation p of the cutter 31. As a result, as shown in FIG. 2, each cutting and raising surface 37 intersects with the blade row a when viewed from the plane direction of the lowering cutter 31, and passes through the tip of the cutting and raising blade 32 to the blade row a. With straight lines intersecting at right angles as the boundary,
The cut groove 36 is provided inside the lowering cutter 31.

Although the following configuration may be omitted, in this embodiment, in order to further improve the cutting efficiency and further reduce the flying speed of the material to be lowered, the blade row a is configured as shown in FIG. The angle θ formed by the blade row a and the normal line C connecting the innermost cutting and raising blade 32a and the rotation center p of the lowering cutter 31 is provided on the rotation direction side with the normal line C as a boundary.

In other words, in order to satisfy the above relationship, the blade row a is formed so that the normal line C is located on the front side in the rotational direction and is inclined at the angle θ.

Note that 14 in FIG. 1 indicates a container included in the food processor shown in FIG. 8.

When the lowering cutter 31 having the above-described structure is stored in the container 14 and used for lowering the material to be lowered, each cutting and raising blade 32 of the lowering cutter 31 lowers its cutting and raising surface 37 to the center of rotation of the cutter 31. Since it is provided toward the p side, the outer edge portion 3 of the cut and raised surface 37
Cutting is performed by biting into the material to be lowered from 7a (see Fig. 2) first. Therefore, the cutting and raising surface 37 is less susceptible to the centrifugal force caused by the rotation of the lowering cutter 31, and the movement of the material to be lowered along the blade row a in the outer circumferential direction of the lowering cutter 31 is prevented.
This cut-and-raised surface 37 allows the material to be lowered to be guided toward the rotation center p side (inner peripheral side) of the lowering cutter 31 as shown by the arrow in FIG.

Therefore, many opportunities to unload the material can be secured, and the speed at which the material flies out of the cutter 31 can be reduced.

Moreover, the blade row a of the lowering cutter 31 in this embodiment
The cutter 3 lowers the material that collides with the normal line C based on the angle θ.
1, toward the rotation center p side instead of toward the outer circumference side. As a result, the action of sending the material to be unloaded to the outer circumferential side of the unloading cutter 31 due to centrifugal force is suppressed, so that it is possible to secure many opportunities for the material to be unloaded to come into contact with the cutting and raising blade 32 and to lower the material to the cutter 31. The speed of jumping out can be further reduced.

By reducing the ejecting speed, the relatively large material to be unloaded is less likely to bite into the layer of grated material that has already been grated and adhered to the inner circumferential surface of the container 14, and adheres to the layer of material. It is possible to reduce the amount of farming done.

Therefore, the grated material adhering to the inner circumferential surface of the container 14 is quickly discharged from the gap 20 along the inner surface of the container 14, and the amount of material adhering to the inner circumferential surface of the container 14 can be further reduced. .

Roughly speaking, the material adhered to the inner circumferential surface of the container 14 is removed by the lowering cutter 31 by contacting the outermost cutting and raising blade 32n of the blade row a of the lowering cutter 31.
It is peeled off by scooping it toward the rotation center p side. In this case, the peeled down material is further brought down by contact with the cutting and raising blade 32, and in combination with this, as described above, more opportunities to be taken down can be secured, thereby further improving cutting efficiency.

Although the above-mentioned embodiment is configured as described above, in the present invention, the blade row may be formed slightly curved with respect to the normal line, or may be formed so as to coincide with the normal line. In addition, in carrying out the present invention, the specific structure, shape, position, etc. of the cut-and-raised blade, cut-and-raised surface, and blade row, etc., shall be limited to the above-mentioned embodiment unless it contradicts the gist of the invention. It goes without saying that the present invention can be configured and implemented in various ways without any modification.

(Effects of the Invention) According to the present invention, the gist of which is the structure described in the above claims, by orienting the cutting and raising surface toward the rotation center of the lowering cutter, contact of the material to be lowered with the cutting and raising blade is prevented. This has the effect of increasing the opportunity to improve cutting efficiency, and reducing the speed at which the material to be unloaded flies out, thereby reducing adhesion to the inner circumferential surface of the container.
