The art knows of a processing tool for mixing or comminuting food materials, with a working shaft (,) which is carried in a shaft housing (,) in the area of its input end and is adapted to be coupled to a drive motor of a kitchen appliance. In the area of its output end, the shaft (,) is centrally carried in a bearing sleeve (,) and fixed in an axial direction and has fastened to its output end a work performing element (,), said shaft housing (,) merging in the area of the output end of the shaft (,) into a flared bell-shaped housing (,) whose inner space is separated from the inner space of the shaft housing (,) by a cover plate (,) through which the shaft output end extends outwardly by passing through a bore (,). The bearing sleeve (,) is inserted and held in an axial direction in a supporting member (,) which bears against the cover plate (,) on the side pointing towards the interior of the shaft housing (,) and overlaps axially with an extension (,) of the cover plate (,). For easy, rapid and accurate assembly, the supporting member (,) is firmly connected with the extension (,) of the cover plate (,) by means of locking members (,), and the cover plate (,), the supporting member (,) and the bearing sleeve (,) are mounted on the working shaft (,) to form a subassembly that is removeable from the processing tool as a unit.

Processing tool for mixing or comminuting food materials

A hand blender powered by an electric motor, for mixing or comminuting foodstuffs in a container, includes a working shaft having an output end, a processing tool attached to the output end of the working shaft, a shaft housing which carries the working shaft, and a bell-shaped casing enclosing the processing tool. The bell-shaped casing has a lower chamber, a lower end bounded by an aperture, and a plurality of lateral openings for the discharge of foodstuffs. A cover plate within the bell-shaped casing forms a fluid-tight seal between the lower chamber and an inner chamber of the shaft housing. The hand blender also includes an air supply structure through which outside air is supplied to the lower chamber of the bell-shaped casing when the bell-shaped casing is immersed in the foodstuffs. The air supply structure includes a flow channel with an inlet side which communicates with the outside air and an outlet side which communicates with the lower chamber of the bell-shaped casing.
