Description

[Detailed description of the invention] In this invention, the object to be cut, such as ginger or garlic, is pressed against the main surface of a rotating grater that is driven by a motor, and the protruding blades formed on the main surface of the grater are used to cut the object. This invention relates to an improvement of an electric grater.

Generally, in this type of grater, when the object to be cut is pressed against the main surface of the rotating grater, the rotational force of the motor is transmitted through the gear mechanism so that the grater can overcome this pressing force and rotate the grater. The signal is transmitted to the grater plate, and the grater plate is rotated at low speed and high torque.

By the way, with the rotating grater mentioned above, the remaining portion of the grated material gets caught between the protruding blades and cannot be collected, so it is necessary to remove only the rotating grater from the main case and wash it frequently. It is preferable that this rotary grater plate can be easily attached and detached from the main body case.

Therefore, even if the rotating grater plate is configured to be detachable from the main body case, since the grater plate is subjected to a pressing force during cutting, the grater plate and the gear mechanism are Unless an appropriate coupling relationship is selected and set, for example, there is a risk that the transmission of rotational force from the gear mechanism to the rotary grater plate during pressing may be hindered.

This idea was made in view of the above circumstances, and a rotary grating plate having a protruding blade on its main surface is supported in a removable and rotatable manner on a shaft provided upright on the bottom of the cutting chamber of the main body case. An annular rack portion that meshes with a driven gear of a gear mechanism connected to a rotating shaft of a motor from the insertion/removal direction is formed on a lower surface of an annular flange formed on an outer surface of an open end of the rotary grater plate. It is an object of the present invention to provide an electric grater in which the rotary grater can be easily attached and detached, and the rotary grater can be rotated smoothly even when pressed by pressing force during cutting. .

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

In FIGS. 1 and 2, 1 is a flat main body case made of synthetic resin, etc., and is composed of an upper case 2 and a lower case 5 in which a dish-shaped portion 4 constituting a cutting chamber 3 is integrally formed. ,

It is configured as a battery cover 23 that covers the battery cover 23.

At both front and rear ends of this battery cover 23, there are upper and lower cases 2, 5.
Retaining portions 26.27 are formed to be removably engaged with each of the side engaging portions 24.25.

Reference numeral 28 denotes a through hole formed in the vertical wall portion 8a of the mounting plate 8, and a driving gear 30 is fixed to a rotating shaft 29 of the motor 7 that passes through the through hole 28 and projects forward.

31 is an intermediate gear meshed with this driving gear 30, and 32 is a driven gear integrally fixed to the intermediate gear 31. These driving and driven wheels 30, 32, intermediate gear 31, etc. constitute a reduction gear mechanism 33. ing.

34 is a bolt that rotatably supports the driven gear 32 on the boss portion 35 of the mounting plate 8.

Reference numeral 36 denotes a shaft protruding from the center of the bottom surface of the cutting chamber 3, and a bearing portion 37a of a grating plate 37 is engaged with this shaft body 36. A plurality of rollers 3 are arranged equidistantly around the shaft body 36.
It is rotatably supported by 8.

Although it is possible to support the grating plate 37 only by the shaft 36, by providing the roller 38, the sliding resistance against the grating plate 37 can be reduced and a stable support state can be ensured.

This roller 38 can also be provided on the bottom side of the grater plate 37, and a ball body can also be used instead of the roller 38.

An annular flange portion 39 is integrally formed on the opening edge of the grater plate 37, and a rack portion 40 that meshes with the driven gear 32 is formed on the lower surface of the flange portion 39. The rotational force of the motor 7 is applied to the grater plate 3 at low speed and high torque through the driving and driven gears 30, 32, etc.
7.

Reference numeral 41 denotes a large number of protruding blades formed on the main surface, that is, the bottom surface, of the grater plate 37, and each of these protruding blades 41 has a height of 3 to 3.
577a, and are formed in a cylindrical shape, and are arranged radially extending linearly from the center outward in the radial direction, as shown in FIG.

Furthermore, one of the plurality of protruding blades 41 is provided on a part of the main surface.
A leveling rib 43 extending radially outward from the center is formed between one blade row 42□ and an adjacent blade row 42°.

This leveling rib 43 is for reliably preventing the fiber fuzz of a workpiece such as a raw material from getting entangled with the cylindrical protruding blade 41.

Reference numeral 44 denotes a grater removal plate which is removably laid on the main surface of the rotary grater plate 37, and is arranged in large numbers so as not to obstruct the protrusion of the plurality of cylindrical protruding blades 41 and the leveling ribs 43 in the laid state. The small hole 45 and the notch 46, and the bearing part 37a of the rotary grater plate 37, which also serves as a gripping knob.
A hollow protrusion 44a is formed which fits into the hollow protrusion 44a.

Reference numeral 47 denotes a cover that covers the cutting chamber 3, and a hinge pin 48 is rotatably fitted to the front end of the cover 47 into a pin receiving portion 49 formed on the outer wall of the cutting chamber 3.

This cover 47 is formed with a cylindrical insertion portion 50 that also serves to position the workpiece M (FIG. 4) in correspondence with the eccentric position of the grater plate 37.

Reference numeral 51 designates a pushing plate for the workpiece M, in which a hinge pin 52 at the base end is fitted into an elongated hole 53 formed on the cover 47 side, so that the hinge pin 52 can be moved in the elongated hole direction; The pushing operation in the arcuate direction can be performed without any hindrance, and the free end is integrally formed with a pushing protrusion 54 that penetrates into the cylindrical insertion portion 50 when the cover 47 is rotated toward the cover 47 side. has been done.

Note that 37b in FIG. 1 is a spout through which the grated juice is drawn out, and is provided in a part of the flange 40 of the grated plate 37.

In the above configuration, when the operating knob 20 is operated to turn on the power switch 18, the rotational force of the motor 7 is reduced in speed through the driving and driven gears 30, 32, etc., and is transmitted to the grater plate 37.

While the grater plate 37 is rotating in the direction of arrow a, the object to be cut, for example, raw IM, is inserted into the grater plate 37 from the insertion portion 50 of the cover as shown in FIG. When you press the main M above, this raw i
M is cut while being bitten off by the tip edge of a cylindrical protruding blade 41 formed radially on the main surface of the grater plate 37.

The protruding blade 41 may be formed in a triangular shape, but if it is formed in a cylindrical shape as in this embodiment, as the cutting progresses, the highly tough fibrous material is torn off by the protruding blade 41. Even if the fibers try to get entangled with the protruding blade 41, even if there is no moisture, the fibers are guided by the smooth side circumferential surface of the protruding blade 41 and slide.

For this reason, the edge portion of the top surface of the tip of the protruding blade 41 continues to effectively contact the surface to be cut of the main M, so that the proper cutting state is continued without rapidly increasing the load on the motor 7, and the proper cutting state is maintained. You can get grated food.

In addition, in this case, the insertion part 50 is provided between the solid bearing part 37a of the grating plate 37 and the meshing position of the driven gear 32 of the rack part 40 of the collar part 39, so that the cutting positions of the main M are on both sides. As shown in FIG.
This can prevent tilting of the rack part 40 and the driven gear 32, tooth skipping between the rack part 40 and the driven gear 32, and idle rotation of the driven gear 32.

Of course, the support roller 38 on the bottom surface 38 of the grater plate 37 works effectively, but when cutting is performed at an intermediate position between the meshing side of the gear 32 and the solid bearing portion 37a of the grater plate 37 as in the above configuration. In this case, the roller 38 is not particularly required.

When grating of raw 9M is completed, the motor 7 stops rotating the grating plate 37, and the removal plate 44 is pulled up with the knob 44a, and the grated ingredients are deposited on the plate 44 and removed from the grating plate 37. Collected from within.

When it is desired to wash the rotary grater plate 37 with water, the cover 47 is rotated to open the cutting chamber 3, and the rotary grater plate 37 is pulled out from the shaft body 36 together with the plate 44 as shown in FIG. Since the driven gear 32 and the rack portion 40 are disengaged in this pulling direction, the grater plate 37 can be easily removed from the main case 1 side.

Furthermore, since the direction of meshing between the rack portion 40 of the rotary grater 37 and the driven gear 32 coincides with the insertion/removal direction (direction indicated by the arrow) of the shaft 36 of the grater 37, the rotation grater 37 is It is easy to install, and the pressing force when lowering the main M is applied to the rack part 4 through the grating plate 37.
Since the meshing portion of 0 and driven gear 32 is biased, both 4
A meshing relationship of 0.0 and 32 can be tightly interlocked.

Further, by forming the rack portion 40 that meshes with the driven gear 32 on the grater plate 37 itself, there is an advantage that the number of parts can be reduced and the structure can be simplified.

As described above, this invention allows the rotary grater to be rotatably and removably supported on the shaft protruding into the cutting chamber of the main body case, and is connected to the driven gear of the gear mechanism connected to the rotating shaft of the motor. With a simple structure in which an annular rack part that meshes with the above-mentioned insertion/removal direction is formed on the rotating grater plate, the rotating grater plate can be easily attached to and removed from the main body case, and the pressing force during cutting is applied to the rack part. It is possible to provide an electric grater that can improve the meshing relationship between the driven gear and the driven gear without adversely affecting the meshing relationship between the gear and the driven gear.
