Embodiment Construction
[0031] figure 1 A motor-operated kitchen machine 1 is shown, which is designed here as a multifunctional cooking mixer. The kitchen machine 1 has a base unit 3 in which a preparation container 4 is installed. In the preparation container 4, a stirrer 7 is also arranged (in figure 1 not shown in ), the food material in the preparation container 4 can be chopped, stirred and / or prepared in other ways and methods by using the agitator. The stirrer 7 is arranged by means of the motor 2 in the basic equipment 3 of the kitchen machine 1 (in figure 1 not shown) drive. The stirrer 7 rotates about the axis of rotation x. For this reason, the stirrer 7 is fitted into a rotating coupling device 8 connected to the motor 2 (in figure 1 not shown in).
[0032] Furthermore, a cover 13 is assigned to the preparation container 4 , which can be connected to the preparation container 4 in a fluid-tight manner by means of closing rollers 15 . Furthermore, the preparation container 4 has a ...

The invention relates to an electric-motor-driven food processor (1), comprising a base device (3), which has an electric motor (2), and comprising a preparation vessel (4) that can be inserted into the base device (3), wherein a vessel bottom (5) of the preparation vessel (4) has a bottom opening (6), which can be closed in a fluid-tight manner by means of a stirring unit (7), which stirring unit(7) can be brought into engagement, through the bottom opening (6), in a coupling device (8) that can be rotated by means of the electric motor (2). In order to prevent preparation material from running into the base device (3) if the stirring unit (7) is inadvertently not installed in the preparation vessel (4), the coupling device (8), according to the invention, has a sealing element (9), which is connected to the coupling device (8) in a rotationally fixed manner and which is designed, in the case of a rotational speed of the coupling device (8) below a defined limit rotational speed, toact against a corresponding immovable housing partial region (10) of the base device (3), in particular in a fluid-tight manner, while following gravity and to release the operative connection above the limit rotational speed because of a rotational-speed-dependent centrifugal force effect. In an alternative embodiment, according to the invention, an immovable housing partial region (10) of the base device (3) adjacent to the coupling device (8) has a flexible sealing element (9), in particular a foam body, which has a fluid-tight surface layer (12), particular a Teflon film, on the side thatacts against the coupling device (8).
Description
technical field [0001] The invention relates to an electric motor-operated kitchen machine with a base unit with an electric motor and a preparation container which can be installed in the base unit, wherein the base of the preparation container has a bottom opening which can be opened by means of A stirrer is sealed fluid-tight, which can be engaged through the bottom opening into a coupling which is rotatable by means of an electric motor. Background technique [0002] Motor-operated kitchen machines having a base unit with an electric motor and a preparation container that can be installed in the base unit are sufficiently known in the prior art. The preparation container can be designed, for example, as a stirred container into which a stirrer can protrude through the container bottom. The blender can be configured, for example, as a knife set with a plurality of knives in order to chop and / or blend food products arranged in the preparation container. Alternatively or ...
