The cooking vessel (50) has a bottom (56) and rotary blade driving means (32) inside a vessel wall (51), and is suitable for working on a support plate (2) of a cooking hob (1) having rotary blade driving means (32) to rotate a lower magnetic coupling member (5). The vessel includes an upper magnetic coupling member (54) connected to the blades (53) and arranged close to an upper surface of said support plate (2) when the vessel (50) is on the plate. The vessel comprises a support element (55) below said bottom (56) of the vessel (51) for resting on the support plate (2), said support element (55) having a coefficient of friction with respect to the support plate (2) low enough to allow the sliding and self-centering of the cooking vessel (50) due to the effect of said lower magnetic coupling member (5).

A mixing apparatus for mixing or stirring substances includes a mixing tank for receiving the substances, a rotor arranged in the mixing tank with which a vane for mixing or stirring the substances can be driven to rotate about an axial direction, and a stator arranged outside the mixing tank and with which the rotor can be driven contactlessly magnetically to rotate about the axial direction in the operating state and is supported magnetically with respect to the stator. A bar extends in the axial direction and is rotationally fixed to the rotor, and a limiting element fixed with respect to the mixing tank cooperates with the bar, with the limiting element being configured such that the bar rotates with respect to the limiting element and with a tilt of the rotor being limited by a physical contact between the bar and the limiting element.

The present invention provides a stirring device and gear train, the stirring device comprises at least one gear; at least one stirring tube; and at least one connecting portion connecting the gear and the stirring tube. Wherein the gear, the connecting portion, and the stirring portion are hollow, and the gear rotates the stirring tube via the connecting portion. Stirring is performed by utilizing the gear and the stirring tube in the stirring device of the present invention. Not only does the biggest flux be achieved per area, but the problem about cross contamination can also be reduced. In addition, in the gear train, the collimation of the stirring device can be increased by a specific hollow gear and a lengthened hollow bearing train forth in the gear train.
