Description

The present invention relates to an electric cooker for cutting vegetables, meat and the like by a cutter rotating in a container.

(B) Conventional technology Conventionally, as an electric cooker for cutting vegetables, meat and the like by pressing a container lid, for example, Japanese Utility Model Publication No. 61-35141
A gazette is known.

In this electric cooker, since the container is made of glass, the radius of the outer peripheral portion of the inner bottom surface becomes large in forming the container.

On the other hand, an electric cooker of this type cuts a material between a container peripheral wall and a cutter tip and between a container bottom and a cutter, so that a distance between the cutter tip and the container peripheral wall, and a distance between the container bottom and the cutter. Needs to be set as small as possible.

However, when forming a glass container, since the R of the inner bottom surface outer peripheral portion is formed large, it is necessary to bend the cutter tip upward so as not to contact the container outer periphery,
When the cutter is bent, there are drawbacks that strength is reduced and cutting efficiency is reduced.

(C) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and has as its object to provide an electric cooker that does not require a step of bending the tip of a cutter.

(D) Means for Solving the Problems The present invention provides a main body having a built-in electric motor, a glass container having an upper surface opening placed on the main body, and having a tip close to the inner peripheral wall of the container and close to a bottom surface of the container. A cutter that is rotated by an electric motor, and a container lid that covers an upper surface opening of the container. A recess is formed all around the outer periphery of the container bottom surface, and the bottom surface of the recess and the inside of the container are formed. The peripheral wall is made continuous by a substantially arcuate curved surface portion, and the tip of the cutter is extended to a position corresponding to the curved surface portion of the recess.

(E) Action By forming a recess in the outer peripheral portion of the inner bottom surface of the container, the diameter of the container near the bottom surface of the inner peripheral surface of the container is maximized, so that the container can be formed without bending the cutter blade. It can be close to the inner peripheral surface.

(F) Embodiment One embodiment of the present invention will be described below in detail with reference to the drawings.

Reference numeral 1 denotes a main body made of a synthetic resin, which has a built-in electric motor 2 and has a projection 1a protruding upward on one side. The electric motor 2 is fixed to a chassis 4 mounted on the main body 1 via a cushion 3. Reference numeral 5 denotes a drive gear fixed to the output shaft 2a of the electric motor 2, reference numeral 6 denotes an intermediate gear that meshes with the drive gear 5, and reference numeral 7 denotes an output gear that meshes with the intermediate gear 6, and is fixed to an output shaft 8 described later.

An output shaft 8 is rotatably supported by the chassis 4 via a bearing 9 and protrudes upward from the main body 1. A joint 10 made of synthetic resin is integrally fixed to the output shaft.

Reference numeral 11 denotes a switch mounted in the protrusion 1a,
12 is constantly urged upward by a spring 13. Reference numeral 14 denotes a hole formed in the upper surface of the protruding portion 1a. A first protrusion 19 described later is inserted into the hole 14 to operate the switch 11 via the operation rod 12.

Reference numeral 15 denotes a glass container which is placed on the main body 1 and has an open top surface, and has a recess 15a formed all around the inner bottom periphery. The concave portion 15a is formed in a substantially arc-shaped cross section in which the inner peripheral wall of the container 15 is continuous at the curved surface portion from the bottom surface thereof, and a tip of a cutter 21 described later extends to a position corresponding to the curved surface portion. The inner wall of the container 15.

Reference numeral 16 denotes a container lid for covering the opening of the container, which is made of an outer peripheral portion 16a made of an opaque synthetic resin that is hard to crack, for example, an ABS resin and a central portion 16b made of a transparent synthetic resin, for example, an AS (acrylonitrile styrene) resin. Has become the outer part 1
6a and the central portion 16b are integrally formed by double molding, ultrasonic welding, bonding or the like. In the outer peripheral portion 16a,
A circumferential rib 17 fitted to the inner surface of the container is formed downward, and a bulging portion 18 is integrally formed on one side of the outer periphery of the outer peripheral portion 16a. A first projection 19 and a second projection 20 are formed downward on the inner top plate of the bulging portion 18. The first projection 19 has a container lid 16 attached to the container 15. When the lid 16 is pressed downward, the switch 11 is inserted into the hole 14 and operates the switch 11 via the operating rod 12. The second protrusion 20 is inserted between the projecting portion 1a of the main body 1 and the container 15 in a state where the container lid 16 is mounted on the container 15 so that the upper part of the container 15 is sandwiched between the projecting portion 1a and the circumferential rib 17. It has been done.

A cutter 21 is detachably attached to the joint 10 of the output shaft 8 and has a blade 22 that rotates in close proximity to the inner bottom surface of the container 15 substantially in parallel.

 Next, the operation will be described.

The container 15 is placed on the main body 1 and the joint 10 of the output shaft 8 is set.
The container 21 is provided with a cutter 21, and the food such as vegetables and meat is put in the container 15, and the upper opening of the container 15 is covered with the container lid 16. In this state, the circumferential rib 17 is fitted on the inner surface of the container 15, and the circumferential rib 17 is
The container 15 is sandwiched between the first projection 17 and the second projection 20 and the first projection
The projection 19 is inserted into the main body 1 through the hole 14 of the protrusion 1a of the main body 1.

When the bulging portion 18 of the container lid 16 is pressed by hand, the first
The projection 19 operates the switch 11 via the operation rod 12, and the electric motor 2 is driven. The cutter 21 is rotated by the drive of the electric motor 2 to cut and cook the food in the container 15. At this time, since the blade 22 of the cutter 21 forms the recess 15a on the outer peripheral portion of the inner bottom surface of the container 15, the blade 22 can approach the inner surface of the container 15 without bending the blade 22, and the bending step can be performed. High efficiency cutting performance can be maintained without increasing.

When the cutting cooking is completed, the pressing of the bulging portion 18 is released.
Then, the container lid 16 is pushed upward by the spring 13, the switch 11 is opened, and the electric motor 2 stops.

Since the outer peripheral portion 16a of the container lid 16 is formed of an opaque synthetic resin that is difficult to break, the strength of the container lid 16 is improved, and therefore, even if the container lid 16 is accidentally dropped, the container lid 16 is damaged. Never. In addition, since the central portion 16b of the container lid 16 is formed of a transparent synthetic resin, the quality of cooking can be confirmed through the central portion 16b.

(G) Effect of the Invention Since the present invention is configured as described above, the manufacturing process of the cutter can be reduced without lowering the cutting efficiency, and the cutting edge of the cutter is not bent. Can be easily obtained.
