Description

[Detailed description of the invention] [Industrial application field] This invention is a switch structure for a small electric cooking device that grates or slices cooking ingredients such as radish and cheese. This invention relates to a switch structure that enables the power switch to be turned on only when a lid covering a cutlery disk for cooking is attached, thereby ensuring worker safety.

[Prior art]

In the case of a conventional small-sized electric cooking device, a switch and a power switch are safely provided in the main body of the drive unit, which has a built-in electric motor that rotationally drives the cutlery disk, and the switch and the power switch are installed in the main body of the drive unit and the cutter disk is housed therein. When the lid is attached to the input opening of the bottle, a switch mechanism is installed that enables the power switch to be turned on by first turning on a safety switch. As a result, the lid is attached to the bottle part, and the power switch can be turned on only when the operator's finger or the like cannot be inserted, thereby ensuring worker safety.

[The problem that the idea attempts to solve]

However, the switch mechanism including the above-mentioned conventional safety switch requires space for installing the safety switch in addition to the power switch. For this reason, in the case of small hand-held electric cooking devices that cook ingredients by directly covering the cutter disc with the lid without using the bottle, since the device itself is small, it is necessary to install a safety switch. It was extremely difficult to secure enough space for this purpose, making it impossible to ensure the safety of workers. That is, in order to ensure the safety of workers, the device itself has to be enlarged, making it impossible to construct a small hand-held electric cooking device. Furthermore, during cooking operations, there is a risk that the lid may come off due to the rotational force of the blade disk being applied to the lid through the cooked cooking material.

The present invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to reduce the size of the device and to enable the power switch only when the lid covering the cutter disc is attached. of
To provide a switch structure for a small electric cooking device that can ensure the safety of a worker by enabling an ON operation and can prevent a lid from coming off during cooking work.

[Means for solving problems]

For this reason, the present invention rotates a cutter disk as an electric motor is driven in a drive unit body that is provided with a gripping part and a mounting part that are large enough to be gripped.
In a small electric cooking device that cooks cooking ingredients fed into a desired state through an input portion of a lid body that covers a cutter disk, the device is movably supported by the drive portion main body, and has an engaging protrusion at the tip and a portion of the cooking material. A slide member having an operating protrusion and a slide member connected to a predetermined power source.
a power switch that turns on when moved to the ON position; a regulating member located in front of the engagement protrusion of the slide member and supported so as to be movable in a direction perpendicular to the moving direction of the engagement protrusion; An elastic member normally urges the regulating member to be located in front of the engaging protrusion by elastic force, and when the lid body is attached to the drive unit body, the regulating member is biased against the elastic force of the elastic member. The present invention is characterized in that it includes an actuating member that is engaged with the engaging protrusion of the moved slide member as it is moved.

[Effect of invention]

Since the present invention is constructed as described above, when the lid is not attached to the drive unit main body and the blade disk is exposed to the outside, the elastic member biases the slide member to engage. A restriction member located in front of the protrusion restricts movement of the slide member. This will cause the power switch to
Retained in OFF state.

On the other hand, when the lid body is attached to the drive unit main body and the blade disk is covered, the regulating member is moved by the abutting actuating member against the elastic force of the elastic member, and the sliding member can be moved. Let it be. When the slide member is operated to move in the above state, the power switch is turned on by the operating protrusion that comes into contact with the movement, and the electric motor is rotationally driven. This causes the cutter disk to rotate in the required direction, and the input cooking material is cooked. Also, during cooking operations, the rotational force of the cutter disk is applied to the lid body through the cooked cooking ingredients, but since the engaging protrusion of the slide member is engaged with the operating member, during the cooking operations This prevents the lid from coming off.
