Abstract

PURPOSE:To prevent the misdrive of a motor by providing a first switch to be closed with the pressing of an operating body projected at a main body external side and a second switch to be closed only at the time of attaching it to the base of the main body or constituting so as to move a switch sliding lever in a direction projected from the main body when the main body is removed from the base. CONSTITUTION:For example, a first switch 13 and a second switch 14 are arranged in a main body 7 internal upper part and an internal side part, respectively, and they are connected in series to a motor 9. An operating body 15 energizing upward with an elastic body 16 closes the switch 13 at the time of a movement downward. A lever 17 is energized in a clockwise direction by an elastic body 18, the lower edge is projected from a through hole at the main body 7 side to a buldging part 8, the upper edge opens the switch 14, simultaneously, the lower edge is pressed by a projecting line 5 at the time of the attachment to a base 1, the lever 17 is rotated in a counterclockwise direction in resistance to the energizing force of the elastic body 18, and the upper edge closes the switch 14. In such a way, since the switch 14 is opened at the time of opening, the safety is secured.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a cooking device suitable for a grater for grating materials such as radish and yam, or an ice shaver.

(B) Conventional technology Conventionally, this type of cooking device has a main body containing a built-in electric motor supported on a base having a cutting blade so as to be movable up and down, and a material holding plate placed below the main body holding down the ice. A device that rotates ice and shaves it with a cutting blade was published in Japanese Patent Application Laid-Open No. 61-865.
It is known from Publication No. 50 (F25C5/12).

This cooking device has a material holding plate that is movable up and down, and when the main body is pushed down, the material holding plate is pushed up by ice, a switch is closed, and an electric motor is closed.

However, when the main body is removed from the base, if you accidentally push up the material holding plate with your fingers or the like, the electric motor will rotate and there is a risk of injury to your fingers or the like.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned problems, and has excellent safety in that the electric motor does not start even if the switch is closed when the main body is removed from the base. The challenge is to provide cooking utensils.

(d) Means for Solving the Problems The first structure of the present invention includes a first switch that has an operating body protruding outward from the main body and is closed when the operating body is pressed, and a first switch that is closed when the main body is mounted on the base. The present invention is characterized in that a second switch that closes is provided, and the first switch and the second switch are connected in series to the electric motor.

The second configuration of the present invention includes an operating body that is supported on the upper part of the main body so as to be able to move up and down and is urged upward by an elastic body, and a sliding rod that is attached to the operating body and is pressed when the operating body is pressed downward. The sliding rod is equipped with a switch for controlling energization of the electric motor, which is closed.
It is slidably supported by the main body and is biased by an elastic body in the direction of protruding outward from the main body, and when the main body is attached to the base, it moves to a position where the switch can be closed, and the main body is moved from the base to a position where the switch can be closed. It is characterized in that the switch is moved to a position where it cannot be closed when removed.

(E) Effect In the first configuration of the present invention, when the main body is removed from the base, the second switch is opened, and even if the first switch is closed by accidentally operating the operating body, the electric motor will not be activated. It never rotates. When the main body is mounted on the base, the second switch is closed, and when the operating body is operated, the first switch is closed, and the electric motor is energized and driven.

In the second configuration of the present invention, when the main body is removed from the base, the sliding rod moves in the direction of protruding from the main body, and even if the operating body is pressed by mistake, the switch will not be pressed by the sliding rod, and the switch will not be pressed by the sliding rod. does not close, so the electric motor does not drive. 0 When the main body is mounted on the base, the sliding rod moves inward to the main body, and when the operating body is pressed, the switch is closed by the sliding rod, and the electric motor is driven. .
