<p>The invention concerns an electrical household appliance for food preparation, comprising a container (1), whereon is arranged a motor housing. A cavity (9) provided on the container floor (21) is designed to co-operate with a pivot (10) of a rotary working assembly (2). The invention is characterised in that a first peripheral contact zone (31) provided around the cavity (9) is designed to co-operate with a second peripheral contact zone (32) arranged opposite around the pivot (10), a separation (e) between the first zone (31) and the second zone (32), defined when the axis of rotation of the working assembly (2) is perpendicular to the plane formed by the first zone (31), ranging between 2 % and 6 % of a distance (r, r') defined with respect to said axis and to the contact point(s) of the first zone (31) with the second zone (32) when the axis is inclined.</p> |
