Abstract
In a safety device for electric motor driven kitchen utensils to make shredding or agitating meats and vegetables in short time, especially the one using one switch and not using conventional safety switch in series connection, the safety device works in such a manner that the switch can be closed only when a container lid is rightly placed on a container and can not be closed when the lid is removed from the rightly closed position, and that when the lid is taken off from the container, the switch is automatically opened. Furthermore, when a push-button to close the switch is being pressed, the lid can not be removed from the container because the lid is inter-locked with the switch to make sure for safety.
