Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the switch operation mechanism of an ice shaver, and simply closes the opening/closing lid provided on the cover on the top of the hopper, which is rotated by a motor together with the rotor blade. In this case, the motor cannot be rotated, but the hopper and rotor plate can be rotated while the opening/closing lid is held down.

(Prior art) A non-rotating cover is provided to cover the rotating member, and at the same time as the opening/closing lid provided on the cover is closed, a sub switch inserted in the motor drive circuit is turned on, and the main switch of the motor drive circuit is held in hand. Thus, food processing machines are known in which the rotary member rotates only when turned on to prevent danger.

However, since the main switch can be turned on and off from the outside, the rotating body may start rotating as soon as you close the opening/closing lid thinking that the main switch is off, making it useless for preventing danger. have shortcomings.

(Problems to be solved by the present invention) In view of the above, the present invention eliminates the main switch that is operated from the outside of the case, and furthermore, it is difficult to solve the problem between the hopper and the rotor by simply closing the opening/closing lid provided on the cover. Regarding ice shavers, where there is a danger that the filled ice blocks may forcefully fly out of the cover by pushing open the opening/closing lid, the motor cannot be rotated unless the opening/closing lid is not only closed but also kept pressed.
Another object of the present invention is to develop a switch actuating device particularly suitable for a small ice shaver, which automatically stops the motor while keeping the opening/closing lid closed when the pressure is released.

(Means for Solving the Problems) The present invention aims to specifically solve the problems mentioned above, and is a cutting machine equipped with a shaved ice outlet facing the cutting blade. A rotor plate is provided inside the case and fixed to a drive shaft driven by a motor and supported by the cutting case, and a cylindrical hopper is fixed to an annular plate connected to the upper end of the rotor plate. It is equipped with a non-rotating cover that covers a hopper, a cutting case, etc., and one side of a rocking piece having a ring portion surrounding the outer periphery of the hopper is attached to the cover, and corresponds to the upper opening of the hopper. On both sides of the inner surface of the opening/closing lid which is hinged to the ice replenishment port of the cover formed by the above-mentioned method, push claws whose lower ends are almost in contact with the rocking piece are protruded, and a switch operating rod that is always raised slightly by springing is attached to the inside of the cover. An ice shaver characterized in that a switch connected to the swinging free end of the motor circuit and inserted in the motor circuit is turned on via a swinging piece and a switch operating rod only while the opening/closing lid is being pressed. Regarding the switch operating mechanism, the structure can be adapted to an ice shaver that does not have a suitable attachment point on the inner surface of the cover for attaching a switch that is turned on by pressing the opening/closing lid.

An embodiment of the present invention will be described with reference to the accompanying drawings.
