Kitchen appliance with weighing device

Abstract

The invention is directed to a kitchen appliance (1) for processing food which includes an appliance base (2) and a weighing device (36) incorporating a force-detecting element (39) capable of determining and indicating the weight of food contained in a vessel (8). During weighing the vessel (8) is carried by the force-detecting element (39) which is in turn connected with the appliance base (2). At least one bearing element (53) vertically slidable against the force of a biased spring (54) is provided between the force-detecting element (39) and the vessel (8). During weighing the vessel (8) rests on the bearing element (53) while being adapted to be latched with the appliance base (2) for operation of the kitchen appliance (1). The force-detecting element is comprised of a bending beam (39) fastened to the appliance base (2) and having strain gauges (41, 42) fitted thereto which supply a signal which is evaluated by an electronic circuitry and displayed. With this weighing device, an impermissible short-time overload condition does not result in damage to the force-detecting element (39). In addition, the weighing device has a good measuring accuracy.
