Abstract

A cleaning device for a mixing vessel of a food processor operated by an electric motor, wherein the mixing vessel has a vessel bottom, a circumferential wall and a cover element and can be connected to a rotary element in a torque-proof manner with the aid of a fasteners and is designed for sweeping over at least a partial area of an inner wall of the mixing vessel and mechanically removing deposits located thereon during a rotation of the rotary element about a rotational axis. The cleaning device is in the form of a bristle element or wiper element and has a C-shaped design that is in contact with the vessel bottom, the circumferential wall and the cover element such that cleaning of the vessel bottom, the circumferential wall and the cover element can take place simultaneously when the mixing vessel is closed with the cover element.

First claim

What is claimed is:

1. A cleaning device for a mixing vessel of a food processor operated by an electric motor, wherein the mixing vessel comprises a vessel bottom, a circumferential wall and a cover element, wherein the cleaning device is configured to be connected to a rotary element positioned in the mixing vessel of the food processor in a torque-proof manner with the aid of a fastening element and is designed for sweeping over at least a partial area of an inner wall of the mixing vessel and mechanically removing deposits located thereon during a rotation of the rotary element about a rotational axis, wherein the cleaning device is designed for a cleaning effect in an axial direction, as well as in a radial direction, and wherein the cleaning device has, viewed in the radial direction, a C-shaped design, which extends convexly outward starting from the rotational axis and comprises at least two opposed limbs comprising a first limb and a second limb, and a center part connecting the two limbs to one another, wherein the cleaning device is configured to be in contact with the vessel bottom, the circumferential wall and the cover element when the cleaning device is positioned in the mixing vessel such that cleaning of the vessel bottom, the circumferential wall and the cover element can take place simultaneously when the mixing vessel is closed with the cover element, wherein the first limb comprises fastening means configured for connecting the cleaning device to the rotary element, and wherein the second limb is formed as a cantilevered free end portion that is not in contact with the rotary element when the cleaning device is fastened to the rotary element, wherein the cleaning device is at least in partial areas made of an elastic material such that the C-shape can be compressed in the direction of the rotational axis under the influence of a force acting from radially outside and/or extended radially outward under the influence of a centrifugal force.

2. The cleaning device according to claim 1 , wherein the cleaning device comprises at least two action surfaces which are not aligned parallel to one another and are essentially oriented perpendicular to one another.

3. The cleaning device according to claim 1 , wherein the cleaning device comprises a bristle element and/or a wiper element.

4. A mixing vessel for a food processor operated by an electric motor, wherein the mixing vessel comprises the vessel bottom, the circumferential wall and the rotary element, wherein the rotary element is configured to be connected to a driveshaft of a rotary drive of the food processor in a torque-proof manner, and wherein the mixing vessel comprises the cleaning device of claim 1 .

5. The mixing vessel according to claim 4 , further comprising the cover element with a central opening, wherein the cleaning device comprises a splash protection element that covers the central opening in the axial direction and is designed for preventing liquid from splashing out of the central opening.

6. A food processor that is operated by an electric motor and comprises a rotary drive and the mixing vessel according to claim 4 , wherein the rotary element of the mixing vessel is connected to a driveshaft of the rotary drive in a torque-proof manner.
