Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric cooker, commonly called a food processor, which is used mainly in households to cook things such as chopping vegetables, mincing fish, and dressing. It is something.

Conventional structure and its problems Conventionally, in this type of cooker, the container was mechanically fixed to the main body by bayonet connection, etc.
Plastic containers were commonly used to make it easier to create unevenness on the container. However, due to the material of glass containers, it is difficult to connect them mechanically by installing a bayonet connection piece, etc. When using glass containers, the following connection configuration was used. .

That is, as shown in FIG. 1, a locking member 2 having a locking pawl 2' is provided on the upper part of the main body 1, and a circular trapezoidal positioning plate 3 is bayonet-coupled to the locking member 2. The glass container 4 is placed on top, and the cylindrical portion 6 provided at the center of the positioning plate 3 is inserted into the hole 5 formed at the center of the bottom of the glass container 4, and the inside of the glass container 4 is inserted into the cylindrical portion 6. The cylindrical fixing member 7 is screwed together, and the glass container 4 is held against the positioning plate 3 by the flange 8 of the cylindrical fixing member 7. However, according to such a conventional electric cooker, since the positioning plate 3 is large enough to receive the entire bottom surface of the glass container 4,
The opposing area between the bottom of the glass container 4 and the top surface of the positioning plate 3 is large, and naturally the gap 9 formed in the opposing area also covers a wide area, posing a problem in that dirt tends to accumulate in the gap 9. In addition, in order to remove accumulated dirt, it is necessary to first remove the positioning plate 3 from the main body 1 and then remove the positioning plate 3 from the glass container 4, which makes it troublesome to attach and detach.
The cleaning workability was poor. By the way, the above-mentioned positioning plate 3 is used for positioning the glass container 4 in the radial direction and fixing the glass container 4. If there is a means to prevent the glass container 4 from moving during operation, the positioning plate 3 only needs to have a positioning function and does not necessarily need a fixing function. The present inventor has considered an electric cooking appliance of this type in which a switch is activated and operated by pressing the container lid from above. With this electric cooker, the glass container can be pressed down and fixed when the switch is activated.
It has been found that the positioning plate 3 does not necessarily require a fixing function.

Purpose of the Invention The present invention takes into consideration the above-mentioned conventional problems, and aims to provide an electric cooker in which the container stand is made smaller so that dirt is less likely to accumulate between the glass container and the positioning plate, and the glass container is easier to clean. shall be.

Structure of the Invention In order to achieve the above object, the electric cooking device of the present invention includes a main body with a built-in electric motor, a glass container placed on the main body, and a rotary drive device that is rotated within the glass container by the electric motor. a cutter that covers the top opening of the container, a container lid that covers the top opening of the container, and a switch that is activated by pressing the container lid downward; A positioning plate is formed with a diameter slightly larger than the hole, and has a cylindrical part that fits into the through hole at the upper part, and a cylindrical part or a plurality of arcuate protrusions at the lower part. A cylindrical portion or a plurality of arcuate projections of a positioning plate that fits into the cylindrical portion or a plurality of arcuate projections is provided on the upper surface of the main body, and a support portion that is in contact with the upper surface of the main body is provided at a position near the outer periphery of the bottom surface of the glass container. This structure prevents dirt from accumulating between the glass container and the positioning plate, and allows the glass container to be easily cleaned.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In Figures 2 to 4, 10 is the main body of the cooker;
11 is a chassis fixed to the main body 10 by a screw 13 via a cushion rubber 12; 14 is a chassis 1;
1 with a screw 15 fixed to its rotating shaft 1
A pinion 17 is attached to the pinion 6. 18 is a main shaft located in the center of the main body 10 and installed upright on the chassis 11 via an oilless bearing 19;
0 is an output gear attached to the main shaft 18 and meshes with the pinion 17. 21 is a leg provided on the bottom plate 22 of the main body 10.

A glass container 23 is detachably placed on the main body 10, and is provided with a skirt-like (or leg-like) support portion 24 in contact with the top surface of the main body 10 near the outer periphery of the bottom surface. 25 is a through hole provided in the center of the bottom of the glass container 23; 26 is the through hole 25;
A positioning plate which has an outer diameter slightly larger than the outer diameter of On the upper surface of the main body 10, there is a cylindrical portion 28 at the bottom of the positioning plate 26 which is fitted internally (or may be externally fitted).
A plurality of arcuate protrusions 29 for positioning the container table
(which may also be a cylindrical part) is provided. Reference numeral 30 denotes a cylindrical fixing member which is inserted into the glass container 23 and whose lower end is screwed to the cylindrical portion 27. The cylindrical fixing member 30 has a flange portion 31 on the outer periphery of the lower portion. A glass container 23 is sandwiched between them. 3
2 is a seal gasket interposed between the flange portion 31 and the glass container 23. The main shaft 18 is passed through the cylindrical fixing member 30, and a cutter mount 34 is detachably connected to the tip of the main shaft 18 via a connector 33. Knife cutters 35 are attached to the upper and lower parts of the cutter mount 34, and 36 is a removable container lid that covers the upper opening of the glass container 23, and has a downward protrusion 37 on one side.

Reference numeral 38 denotes a rising portion provided on one side of the main body 10, at the tip of which there is a recess 3 into which the projection 37 can enter.
9, and a push button 41 is provided through the bottom of the recess 39, which is constantly biased upward via a spring 40 and pushed down by the protrusion 37 of the container lid 36. Reference numeral 42 denotes a switch provided near the bottom of the push button 41, which is connected to the electric motor 14, and functions to enable the electric motor 14 to operate when the push button 41 is pressed and turned on.

Next, the operation and operation of the electric cooker will be explained. A glass container 23 is placed on the main body 10, and a cutter mount 34 to which a knife cutter 35 is attached is fitted into the connector 33. Next, after putting the object to be cut into the container 23 and covering the glass container 23 with the container lid 36, when the container lid 36 is pushed down by an external force, the protrusion 37 pushes down the push button 41, and the switch 42 turns on. Without electric motor 1
4 becomes operational. Therefore, the electric motor 14 is driven by a switch (not shown), and the object to be cut is cut by the knife cutter 35. On the other hand, if the external force pushing down the container lid 36 is removed, the push button 4
1 is pushed up by the spring 40, and the switch 4
2 performs OFF operation.

By the way, the positioning plate 26 in this embodiment
The structure is such that only the horizontal positioning of the glass container 23 and the main body 10 is performed, and the vertical positioning is left to pressing the container lid 36.
Therefore, even if the positioning plate 26 has a small outer diameter, it functions satisfactorily, and the contact area between the glass container 23 and the positioning plate 26 is much smaller than in the conventional example, and dirt is less likely to accumulate in the contact area. Further, since the positioning plate 26 is small, the glass container 23 can be cleaned while the positioning plate 26 is fixed to the glass container 23.

Effects of the Invention As described above, according to the present invention, since the contact area between the glass container and the positioning plate is small, it is difficult for dirt to accumulate between the two, and since the positioning plate is small, the positioning plate can be fixed to the glass container. Can be washed as is. Therefore, the glass container can be easily cleaned. In addition, since the fitting diameter between the positioning plate and the cylindrical part or the plurality of arcuate protrusions provided on the top surface of the main body is small, the variation in the dimensions of the two is small, and the horizontal wobbling of the glass container is almost eliminated. It can definitely be prevented.
