Abstract
This invention provides a safety system for electrically operated kitchen appliances such as blenders, food processors and the like, to protect users from contact with cutting or macerating implements which, in operation of such appliances, are rotated at reasonably high speeds by powerful electric motors. In order to provide a reliable and robust safety system which is economical to manufacture, the invention utilises a detent member () which is rotatable with either the motor or the implement (). A trapping member (), which is mobile between two positions along the motor's axis of rotation, but which cannot rotate, traps or releases the detent member, depending upon the trapping member's position. The trapping member () is moved into the position at which the detent member () is released only when a container () is correctly inserted into place to contain the implement. The invention also provides an electrically powered kitchen appliance incorporating such a safety system.
