Cover 2 not only serves to seal the bowl 1, but also includes a motor 3 low power together with the drive mechanism Sivalinga disc 4 rotating on the bottom of the bowl 1. The shaft 5 transmits torque from the drive mechanism of the electric motor 3 Susalny disc 4. Susalny disk can be, for example, for whipping egg whites or cream.

A support shaft 5 in the cover 2 by driving the motor 3 is an axial-radial bearing 6.

On the bottom side of the cover facing the bowl, is the sealing section 7. This sealing section is designed for tight shut-off in the Cup 1 fluid substance: liquid, thick masses of ice cubes, etc. In the center of the sealing section 7 has a hole for passage of the shaft 5.

In the cover 2 has, in addition, a built-in switch with 8 security feature. Thanks to this switch chopper can operate only when kr is the Cabinet 2 as follows closes the Cup 1.

In figures 2A-2D shows the different positions of the switch according to the present invention. Portion 11 of the casing shown in section. Installed turntable 12, which rotates Board 13. On Board 13 is a metal contact spring 14, which can cuddle up to a counter contact 15. When both contacts are pressed to each other on the circuit Board 13 is formed corresponding circuit.

Above the metal spring contact 14 is the governing body 16 in the form of keys. There is a ledge 17 in the form of a rod, directed from the governing body 16 to the metal spring contact 14.

In the position depicted in figa, the protrusion 17 are pressed on the metal contact spring 14, and a metal contact spring 14 is not loaded and no pressure in turn on a counter contact 15. This means that the switch is open (the "0"position), and kitchen appliance is disabled.

On FIGU shows the position in which the governing body 16 is pressed down in the direction of the metal spring contact 14. The protrusion 17 in this position may be located before the metal spring contact 14, he can touch the metal spring contact 14 or slightly bend it down towards the counter-contact 15. In any case, a metal contact spring 14 still applies TSA is echnolo contact 15, so that the switch remains open (the "0"position). Thus, only one movement of the control shown in the drawing by the arrow And, still not enough to include kitchen appliance.

On figs shows the position in which the portion 11 of the body worn properly on another shows a section of the housing. To pass this status on the switch portion 11 of the casing has a hole 18, and 13 for holding and rotation in the support 12 is L-shaped holder 19, which on the one hand is connected with the shaft bearing 12, and on the other hand is directed to the hole 18 passes through the hole (cf. figa and 2B). In the horizontal position, i.e. when the portion 11 of the casing is not installed on another part of the body, the holder 19 is held at one end through the hole 18 (figa and 2B).
