Prior Art For example, the conventional electric grater shown in Japanese Utility Model Publication No. 59-11710 has a switch case that is attached to the upper surface of a drive unit case, and is attached to a saucer body that is attached to the drive unit case. The lid body is equipped with a switch operation mechanism that turns the switch ON and OFF, and the switch operation mechanism is installed when the lid body is properly attached to the saucer body.
When turned ON, the motor is driven to rotate the cutting blade to grate the material.

Problems to be Solved by the Invention However, the above-mentioned conventional electric grater is arranged such that the switch case is located substantially within the saucer body. For this reason, the switch case must be provided with a waterproof cover to cover the protruding rod that turns the switch ON, and the switch operation mechanism must be composed of a push button, a spring, an operating rod, a cam, etc., making the switch mechanism complicated. As a result, the number of parts increases, making it impossible to reduce the size and cost of the device itself.

Further, in the case of the above electric grater, even when the lid is not attached to the saucer, the switch can be turned on by pressing the protruding rod. As a result, there is a risk that the worker may be injured by the rotating cutting blade, and there is a problem in that the safety of the worker cannot be ensured.

The present invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to rotate the rotary blade only when the opening of the container is closed, without the need for a safety switch. An object of the present invention is to provide a switch structure for an electric cooking device that can be driven.

Another object of the present invention is to provide a switch structure for an electric cooking device that can reduce the size and cost of the device.

Means for Solving the Problems Therefore, the invention of claim 1 provides an electric cooking device that cooks input cooking ingredients to a desired state using a rotary blade rotated by an electric motor. The lid is attached to cover the rotary blade and has an actuating piece that protrudes radially on a part of the outer periphery, and the lid can be moved in a direction that almost matches the installation direction at a position where the lid can come into contact with the main body case. A supported regulating member, an elastic member that normally biases the regulating member in the direction opposite to the direction in which the lid is attached, and a proximal end rotatably supported with respect to the main body case, and a distal end A state in which the operating lever is rendered unrotatable by abutting against the regulating member that is biased and moved by the elastic member, and the regulating member is moved against the elastic force of the elastic member due to contact with the operating piece. The operation lever rotates when the tip is released from contact with the regulating member when pressed.
It is characterized by comprising a switch member that is turned ON.

Further, the invention of claim 2 provides a switch structure for an electric cooking device that cooks input cooking ingredients to a desired state using a rotary blade rotated by the drive of an electric motor. The lid has an operating piece that protrudes in the radial direction on a part of its outer periphery, and is movable in a direction that almost matches the mounting direction of the lid at a position where the operating piece of the lid can come into contact with the main body case. A regulating member that is supported by and has a through hole in a part, an elastic member that always uses elastic force to bias the regulating member in the opposite direction to the direction in which the lid is attached, and a proximal end that can be rotated to the main case.

A shaft portion 25e is integrally formed at the lower end of a hanging wall 25d integrally formed at the tip of the operating lever 25, with an axial length corresponding to the distance between the electrode 29 and the electrode plate 31. On the other hand, a regulating member 33 is disposed within the mounting recess 23 corresponding to the shaft portion 25e, and the distal end of the regulating member 33 is always kept at a constant position due to the elastic force of a compression spring 35 provided within the mounting recess 23. It is urged to move so as to be located on the side of the recess 3f. Further, the regulating member 33 has a hole 33a.
The hole 33a is formed in a size that allows the shaft portion 25e to enter into the hole 33a, and when the regulating member 33 is moved toward the recess 3f, the hole 33a is located in a non-protruding state with the shaft portion 25e. When 33 is moved to the opposite side, the shaft portion 25e is positioned so as to be inserted. When the hole 33a is located at a position where the shaft portion 25e can enter, rotation of the operating lever 25 due to pressing is permitted.

Next, the operation of the electric cooking device 1 configured as described above will be explained with reference to FIGS. 4 to 7.

In FIG. 4 showing the power OFF state, FIG. 5 showing the power ON possible state, FIG. 6 showing the power ON state, and FIG. 7 showing the cooking state, the bottom plate 17 is placed against the upper surface of the semi-cylindrical part 3b With the drive shaft 9 inserted into the through hole 17d, the engagement protrusion 17e is engaged with the engagement recess 3d, and the engagement part 17f is engaged with the engagement protrusion 3e, respectively. Then, the boss 19a of the rotary blade 19 is attached to the upper end of the drive shaft 9 inserted through the through hole 17d.
The rotary blade 19 is attached by inserting and fitting.

When the rotary blade 19 is attached to the drive shaft 9 and the operating lever 25 is pressed with the input lid 21 not attached, the elastic force of the compression spring 35 causes the regulating member 33 to move in the direction of the solid arrow shown in FIG. It is moved in the A direction, and the hole 33a is positioned so that the shaft portion 25e cannot enter therein. Therefore, even if the operating lever 25 is pressed, its rotation is restricted, thereby maintaining the non-contact state of the electrode plate 31 with respect to the electrode 29, and driving of the electric motor 5 is avoided.

On the other hand, after the input lid 21 is attached to the semi-cylindrical portion 3b to which the bottom plate 17 and the rotary blade 19 are attached so that its operating piece 21g is located within the recess 3f, as shown in FIG. When the rotating operation is performed in the direction of the solid arrow B, the engaged portions 21f are first engaged with the engaging protrusions 17g, and the rotating state is maintained. Furthermore, the compression spring 3 is in contact with the regulating member 33 that comes into contact with the actuating piece 21g that moves in the direction of the solid arrow B.
5 in the direction of the solid arrow C shown in FIG. 5 so that the hole 33a and the shaft portion 25e are aligned.

When the operation lever 25 is pressed in the above state, the shaft portion 25e is allowed to enter into the hole 33a, so that the sixth
Operation lever 2 in direction D of the solid line arrow shown in the figure
5 rotations are allowed. And the above operation lever 2
As the electric motor 5 rotates, the electrode plates 31 come into contact with the electrodes 29 and short-circuit them.
is battery-driven, and the rotary blade 19 is rotated in a desired direction.

When the cooking material is introduced through the cylindrical portion 21e while the rotary blade 19 is rotating, the cooking material is cut into a desired size and shape by the rotating rotary blade 19 and dropped onto the bottom plate 17. After that, it is guided to the notch side by the scraping plate 19b, and the extraction part 21 is removed.
It is discharged to the outside from d.

In this way, in this embodiment, even if the operating lever 25 is pressed while the input lid 21 is not attached to the main body case 3, the regulating member 33 moved by the elastic force of the compression spring 35 prevents the operating lever 25 from being pressed. The rotation of the electrode 29 and the electrode plate 31 are restricted, and contact between the electrode 29 and the electrode plate 31 is restricted. As a result, the rotary blade 19 does not rotate when the charging lid 21 is not attached, and safety can be ensured. On the other hand, when the loading lid 21 is normally attached to the main body case 3 to which the rotary blade 19 is attached, the control member 33 that moves as the loading lid 21 is attached allows the operating lever 25 to be pressed and rotated. , the electric motor 5 can be rotated by bringing the electrode plate 31 into contact with the electrode 29 .

In the above description, the hole 33a is formed in the regulating member 33, and when the regulating member 33 is moved against the elastic force of the compression spring 35 by attaching the input lid 21, the hole 33a is formed in the regulating member 33.
The operating lever 25 is configured such that the shaft 25e can be inserted into the shaft 25e.
Claim 1
In this case, when the lid is not attached, the tip of the operating lever is brought into contact with the upper surface of the regulating member that has moved due to the elastic force of the elastic member, making it impossible to press it, while when the lid is attached In some cases, the control member may be configured to release the abutting state between the control member, which has moved against the elastic force of the elastic member, and the tip end of the operating lever, thereby enabling the pressing operation.

Effects of the invention Therefore, the present invention makes it possible to drive the rotary blade to rotate only when the opening of the container is closed, without providing a particular safety switch.
It is possible to provide a switch structure for an electric cooking device that can reduce the size and cost of the device.
