Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electric cooker that is mainly used in general households and is capable of cooking grated radish, grated radish, and the like.

(Structure of conventional example and its problems) A conventional electric cooker of this type has a structure as shown in Fig. 1, and has a main body with a built-in electric motor (not shown). A main shaft 1 that is rotationally driven by an electric motor projects upward. Further, a container 3 in which a guide tube 2 through which the main shaft 1 is inserted projects upward from the center of the bottom surface is placed on the main body, and within this container 3 is a disc-shaped Oroshi cutter 4 that is connected to the main shaft 1 and rotates together. A container lid 5 is attached to the opening of the container 3. When cooking with this electric cooker, place the object 6 to be cut, such as radish or yam, on the oroshi cutter 4 in the container 3, close the container lid 5, and then start energizing the electric motor. The rotation is transmitted to the Oroshi cutter 4 via the main shaft 1, and the workpiece 6 is cut into a workpiece 7 such as grated radish or grated yam.
becomes.

However, in such a conventional electric cooker, especially when cooking a large amount of highly viscous cuttings 7 such as yam, the cuttings accumulated under the oroshi cutter 4 in the container 3 are larger than the oroshi cutter 4. This has caused an inconvenience in that it climbs over the upper end of the guide tube 2 of the container 3 located below and leaks out of the container 3 through the inside of the guide tube 2.

(Object of the Invention) The present invention has been made in view of the above-mentioned drawbacks of the conventional example. To provide an electric cooker capable of detecting that a portion of the container is filled with cutting materials.

(Structure of the Invention) In order to achieve the above object, the electric cooker according to the present invention is provided with an annular wall surrounding the rotation axis of the oroshi cutter at a certain interval on the lower surface of the oroshi cutter, and a circular wall surrounding the rotation axis of the oroshi cutter on the outer peripheral surface of the annular wall. A plurality of thick-walled parts each having a slope leading downward in the direction of the direction are provided, and a plurality of holes are provided close to the outside of the annular wall of the Oroshi cutter and shaped along the outer periphery thereof, and a ring-shaped part is provided on the bottom of the container. A cylindrical wall is provided that closely surrounds the outer periphery of the wall and extends to the vicinity of the bottom surface of the Oroshi cutter. With this configuration, the portion of the container below the Oroshi cutter is protected from cutting objects. When it is full, the cuttings on the bottom side of the Oroshicutter will spray out through the multiple holes provided in the Oroshicutter to the top side and circulate inside the container, so the cuttings will go over the guide tube in the center of the container and leak out of the container. In addition, it is possible to detect that the portion of the container below the Oroshi cutter is filled with the cut material by the phenomenon that the cut material is ejected onto the upper surface of the Oroshi cutter.

(Description of Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a diagram showing the configuration of an embodiment of the present invention. In FIG. 2, reference numeral 8 denotes a main body having a protruding portion 8a that protrudes upward from a part thereof, which houses an electric motor 9, and a main shaft 10, to which rotation is transmitted from the electric motor 9 via a reduction mechanism, protrudes upward. There is. 1
1 is a container placed on a main body 8, and a guide tube 12 through which a main shaft 10 is inserted projects upward from the center of the bottom surface. Reference numeral 13 denotes an Oroshi cutter that is rotatably driven within the container 11, and is composed of a disc-shaped cutter tooth 13a and a cutter tooth holding portion 13b that holds the cutter tooth 13a. Holding part 13
b are detachably connected to each other. 15 is a container lid that covers the opening of the container 11, and the protrusion 8 of the main body 8
A protrusion 15a protruding downward is provided at a position corresponding to a. A switch 16 is provided inside the tip of the protrusion 8a and is turned on to energize the electric motor 9 when the container lid 15 is pushed down and the protrusion 15a is pushed into the protrusion 8a. In addition, as shown in FIGS. 3, 4, and 5, the Oroshi cutter 13 has an annular wall 17 extending downward so as to surround the outside of the guide tube 12 on its lower surface at the end of the cutter tooth holding portion 13b. An annular wall 17 extending from the section
A plurality of holes 18 are provided in the cutter tooth 13a, and the holes 18 are formed in the outer peripheral surface of the annular wall 17 in the direction of rotation of the Oroshi cutter 13 shown by the arrow in FIG. A plurality of thick portions 19 are formed, each having a slope 19a leading downward toward the bottom. A cylindrical wall 20 is provided on the bottom surface of the container 11 so as to be close to and surround the outer periphery of the annular wall 17 and extend to near the lower surface of the cutter teeth 13a.

Next, the operation of this embodiment will be explained. First, the container 11 is placed on the main body 8, and the Oroshi cutter 13 is fitted into the connector 14 passing through the guide tube 12 and installed in the container 11. Then, as shown in FIG. 6, the object to be cut 21 is placed on the Oroshi cutter 13, the opening of the container 11 is covered with the container lid 15, and the container lid 15 is pushed down by hand.
The protrusion 15a of No. 5 turns on the switch 16 provided within the protrusion 8a of the main body 8. Then, the electric motor 9 is started and its rotation is transmitted to the Oroshi cutter 13 via the main shaft 10, and the Oroshi cutter 13 rotates to cut the workpiece 21. When cutting is completed, when the container lid 15 is stopped being pushed down, the container lid 15 is lifted by a spring built into the switch 16, and the switch 16 is turned off. On the other hand, the cut object 22 of the workpiece 21 cut by the Oroshi cutter 13 is blown toward the outer circumference of the Oroshi cutter 13 due to the centrifugal force generated by the rotation of the Oroshi cutter 13, and the cut material 22 is blown away from the outer edge of the cutter teeth 13a and the container 11. It falls to the bottom of the container 11 through the gap with the inner wall and accumulates on the underside of the oroshi cutter 13 of the container 11. Here, as the amount of cuttings 22 accumulated in the container 11 increases, when the cuttings 22 try to climb over the upper end of the cylindrical wall 20 and enter the inside thereof, the annular wall 17 and the cylindrical wall 20
The gap between the cutting object 22 and the cutting object 22 is small, and even if the cutting object 22 enters this gap, it will be pushed back upward by the slope 19a facing in the direction of rotation of the thick part 19 formed on the outer peripheral surface of the rotating annular wall 17. Therefore, the cutting object 22 does not enter the inside of the cylindrical wall 20. In addition, the amount of cuttings 22 increases further, and the container 1
The lower surface side of the Oroshi cutter 13 in 1 is the cut object 22
When it becomes full, the internal pressure of the accumulated cuttings 22 increases, and the cutter teeth 1 of the Oroshi cutter 13
Cutting material 22 is ejected from the lower surface side to the upper surface side through the hole 18 provided in 3a. Then, as shown by the arrow in FIG.
It falls again to the lower surface side of the Oroshi cutter 13 through the gap between the outer edge of the container 11 and the inner wall of the container 11, and circulates inside the container 11. At this time, the thick part 19 of the annular wall 17
This not only pushes back the cutting object 22 that has entered the gap between the annular wall 17 and the cylindrical wall 20, but also pushes back the cutting object 22 that has entered the gap between the annular wall 17 and the cylindrical wall 20. As shown by the arrow inside, the cutting material 22 can flow out through the hole 18 to the upper surface side of the Oroshi cutter 13, and as shown in FIG. If the upper end of the slope 19a of the thick part 19 is located directly below the cutter 13, the cut object 22 pushed back by the thick part 19 can be more efficiently flowed out to the upper surface side of the oroshi cutter 13. Therefore, the Oroshikutter 1 in the container 11
Even if the lower side of the container 11 is filled with cuttings 22, the cylindrical wall 2
Since the cutting object 22 does not penetrate inside the
can be prevented from climbing over the guide tube 12 and leaking out of the container 11. In addition, the cutting object 2
2 is ejected from the lower surface side of the Oroshi cutter 13 to the upper surface side, it can be detected that the lower part of the Oroshi cutter 13 in the container 11 is filled with cuttings 22.

Note that the thick portion 19 provided on the outer peripheral surface of the annular wall 17
This is not only to push back the cuttings 22 that have entered the gap between the annular wall 17 and the cylindrical wall 20, but also to prevent the annular wall 17 from deforming due to the pressure of the cuttings 22 accumulated in the container 11. It also plays a reinforcing role.

(Effects of the Invention) As explained above, the present invention prevents the cutting objects from entering the inside of the cylindrical wall rising from the bottom of the container when the portion of the container below the oroshi cutter is filled with cutting objects. Since the cut material is ejected from the hole provided in the Oroshi cutter to the upper surface side and circulated inside the container, the cut material does not leak out of the container from the guide tube inside the cylindrical wall. This has the effect of being able to sense that the lower surface of the Oroshi cutter in the container is filled with cuttings due to the phenomenon of spouting to the upper surface.
