Patent ID: 8469586

Claim:
Kitchen appliance for processing food, wherein the kitchen appliance comprises: a drive unit, which has a cutting and/or stirring unit and is swivel-mounted in a support unit so that the drive unit, together with the cutting and/or stirring unit, can be swiveled from a rest position into an operating position and back again; an attachment section which is designed to accommodate a mixing container in such a way that the attachment section and the mixing container define a hermetically sealed mixing space, in which the cutting and/or stirring unit is located, wherein the attachment section is comprised of a cylindrical recess in the drive unit, and wherein multiple pilot slots designed to accommodate lugs of complementary shape of a mixing container are provided on the inside of the circumference of the attachment section, with each of the pilot slots transitioning to a groove section extending a short distance in the circumferential direction, wherein each groove section narrows with increasing distance from the pilot slot standing in connection therewith, so that when the lugs of a mixing container are introduced into the groove sections of the pilot slots, the mixing container is pressed against the floor of the attachment section; wherein, when the drive unit is in the operating position, the cutting and/or stirring unit is arranged in the lower section of the mixing space in such a way that food located in the mixing container is fed to the cutting and/or stirring unit on account of gravity, and wherein at least one safety switch projects under preloading into the groove section of one of the pilot slots, wherein in this extended position of the safety switch, the supply of electricity to the drive unit is interrupted, and wherein, if a mixing container is then brought into a fluid-tight engagement with the drive unit, a lug of the mixing container introduced into the groove section pushes the safety switch against the preloading into a retracted position in which the interruption in the supply of electricity to the drive unit is removed.
