Description

[Detailed description of the device] [Industrial applications]

The idea is to grate cooking ingredients in a handheld state,
The present invention relates to a small electric cooking device that cuts into a desired shape, and more particularly, to a power switch structure that turns on and off an electric motor that rotationally drives a blade member.

[Prior art]

The applicant of the present application has previously disclosed in Japanese Patent Application No. 1-66118 a power switch for driving an electric motor, a slide member movably supported by a drive unit main body, and an ON switch for operating the power switch in association with the movement, Power ON position of slide member and power OF
Engagement for selectively engaging the first and second engaged parts respectively provided at the F position and the first and second engaged parts to maintain the moving state of the slide member. We proposed a switch structure of a small electric cooking device with a member. In the above switch structure, the slide member is the power source.
When the movement operation is performed to the OFF position, the power switch is maintained in the OFF state by the engagement of the engagement member with the second engaged portion, and when the movement operation is performed to the power ON position, the first
Power switch by engaging the engaging member with the engaged part of
The ON state is maintained. Thus, the driving member can be held by one hand and the cooking member can be thrown in by the other hand to cook in a desired state, thereby improving work efficiency.

[Problems to be solved by the device]

However, in the above switch structure, even when the slide member is not continuously pressed, the power switch
Since the ON state is maintained, when the power switch is to be immediately turned OFF, the slide member has to be moved again and the rotation of the blade member cannot be immediately stopped. Also, when the small electric cooking device is dropped while the blade member is rotating, the rotating blade member may be exposed due to the impact of the drop and the rotating blade member may damage the lid and the dish member. There is a risk of becoming larger. The present invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to reliably interrupt the rotation of the electric motor when a finger or the like is separated from the slide member. It is possible to provide a small electric cooking device provided with a switch structure that can improve the safety of workers.

It is characterized in that a small electric cooking device is constituted by a switch member that is turned on to drive a power supply motor when the power supply is moved to an ON position against a force. Further, according to the invention of claim 2, a main body case provided with a drive part rotatably supporting a rotary shaft drivingly connected to a gripping part and a built-in electric motor, and an upper surface of the drive part inserted through the rotary shaft. In a small-sized electric cooking device including a dish member that covers the blade, a blade member that is attached to a rotating shaft that passes through the dish member, and a lid that is attached to the drive unit so as to cover the blade member, a mounting direction of the lid body to the drive unit. And a regulating member that is movably supported to move in contact with an operating piece provided on the lid, and a first member that always urges the regulating member in a direction opposite to the attaching direction of the lid to the drive unit. An elastic member, a movable member that is movably supported between a power-off position and a power-on position that are orthogonal to the axis of the rotating shaft, and has a shaft portion that abuts against the regulating member at its tip end, and a movable member Is always urged to the power off position A small electric cooking device is formed from a second elastic member and a switch member that is turned on to drive an electric motor when the movable member is moved to the power-on position against the elastic force of the second elastic member. It is characterized by configuring.

[Function of the device]

According to the invention of claim 1, when the movable member is operated to move from the power OFF position to the power ON position against the elastic force of the elastic member while holding the grip portion, the switch member is turned ON to operate the electric motor. Drive to rotate. As a result, the blade member rotates in a predetermined direction, and the input cooking material is cooked in a desired state. When the moving state of the movable member is released during the cooking operation, the movable member automatically moves from the power-on position to the power-off position by the elastic force of the elastic member to turn off the switch member. As a result, the driving of the electric motor is interrupted and the rotation of the blade member is stopped. Further, according to the invention of claim 2, when the lid is attached to the drive part to which the dish member and the blade member are attached, the regulating member causes the elastic force of the first elastic member by the operation piece of the lid. It moves against and the movable member is made movable. When the movable member is moved from the power OFF position to the power ON position against the elastic force of the second elastic member in the above state, the switch member is turned ON and the electric motor is rotationally driven. As a result, the blade member rotates in a predetermined direction, and the input cooking material is cooked in a desired state. When the moving operation state of the movable member is released in this cooking state, the movable member is powered off from the power-on position by the elastic force of the second elastic member.
Move to the position and turn off the switch member to interrupt the drive of the electric motor. As a result, the rotation of the blade member is stopped. Then, when the cooking work is completed and the lid is removed from the drive unit, the regulating member is moved by the elastic force of the second elastic member and is moved to the front surface of the shaft portion of the movable member. Therefore, even if the movable member is operated to move from the power-OFF position to the power-ON position, the movement of the movable member is restricted by the contact of the shaft portion with the restriction member, so that the switch member is held in the OFF state.
