Abstract
The invention relates to a household appliance (1) comprising a movable first functional unit (10) for providing a first appliance function to a user, an electrical second functional unit (20) for providing a second appliance function to the user, and an operating device (11) for powering the first functional unit (10), comprising an electric motor (12), a connection (13) for supplying power to the electric motor (12), and a pre-circuit (30) connected between the connection (13) and the electric motor (12), wherein the pre-circuit (30) comprises a current limiting element (31) for limiting a current (200). The invention also relates to a method (100) for operating a household appliance (1).
Claims17
A food processor comprising:
- a movable first functional unit for providing a first device appliance to a user;
- and
- an operating device for powering the first functional unit, comprising:
- an electric motor,
- a connection for supplying power to the electric motor, and
- a pre-circuit connected between the connection and the electric motor;
- the food processor further comprising:
- a cooking vessel which is configured to be detachable from the operating device;
- and
- an electrical second functional unit for providing a second appliance function to the user,
- the second functional unit comprising an electrical resistance heater with a resistance element for heating the resistance heater, the electrical resistance heater thereby being configured to heat food in the cooking vessel by the resistance element to perform the second appliance function, wherein at least a section of the resistance element forms a current limiting element for limiting a current in the pre-circuit by being electrically connected to the pre-circuit, and
- the second functional unit with the current limiting element being arranged in the cooking vessel, thereby being detachable from the motor of the operating device.
A method for operating a food processor with a movable first functional unit for providing a first appliance function for a user, comprising at least the following step:
- operating an operating device for powering the first functional unit of the food processor by an electric current,
- wherein the operating device comprises:
- an electric motor,
- a connection for supplying power to the electric motor, and
- a pre-circuit connected between the connection and the electric motor;
- the food processor further comprising:
- a cooking vessel which is configured to be detachable from the operating device;
- and
- an electrical second functional unit for providing a second appliance function to the user,
- the current in the pre-circuit being limited by a current limiting element formed by the second functional unit, and
- the second functional unit comprises an electrical resistance heater with a resistance element for heating the resistance heater, the electrical resistance heater thereby being configured to heat food in the cooking vessel by the resistance element to perform the second appliance function, wherein at least a section of the resistance element forms the current limiting element for limiting a current in the pre-circuit by being electrically connected to the pre-circuit, wherein the current limiting element is arranged in the cooking vessel, thereby being detachable from the motor of the operating device.
