Embodiment Construction

[0028] figure 1 A kitchen appliance 1 according to the invention is shown, which consists of a stirring rod. A tool 17 consisting of a cutter or a pulverizing tool is attached to the stirring rod 2 by means of a quick-clamp connection 72 . The tool 17 has a tool head 46 with a corresponding knife or mixing element (not shown). The stirring rod 2 has a housing 5 comprising a first outer housing 56, a housing clamping cover 63 formed by a clamping part 61, and a second outer housing 57 (see figure 2 ). The state-of-charge display 27 shows whether the stirring rod 2 has been operated, in particular whether it is charged sufficiently vigorously. The stirring rod 2 is put into operation by means of the on-off switch 67 . However, the switch-on switch 67 is only effective when the switch-on switch is unlocked by the safety switch 68 . The safety switch 69 , which is independent of the switch-on switch 67 , acts as an electrical lock, which only unlocks or releases the switch-o...

Abstract

The invention relates to an electric-motor kitchen appliance (1), in particular an electric-motor handheld device, preferably a hand mixer (2), which comprises a switch (67). The invention also relates to a finger-actuated electric control (68) for the switch (67), and to a method for switching on / off a kitchen appliance (1). The switch (67) is unlocked when the safety switch (69) is actuated by the finger of a user. The safety switch (69) is electronically switched. The invention is characterised in that possibility of unintentionally operating the electric-motor of the kitchen appliance (1)is reduced due to the manual operation of the two separate switches. As a result, the safety of the electric-motor kitchen appliance (1) in the household is significantly increased.

Description

technical field [0001] The invention relates to an electric kitchen appliance, in particular an electric hand-held appliance, preferably a stirring rod, with a switch, and a method for switching the kitchen appliance on and off. Background technique [0002] From DE 42 20 233, a household appliance for processing food is known, which comprises an electric motor and a battery, wherein the battery is charged by adjusting the household appliance into the charging position. [0003] A disadvantage of the known electric kitchen appliances is that there is a certain danger that the kitchen appliance is switched on by accidental and inadvertent pressing of the switch. This problem arises especially with stirring bars, which have cutters that rotate in free space or comminution knives that rotate on their tool heads. These sharp knives cannot be protected by a cover due to their functional limitations. Inadvertent manipulation of the switch may cause injury due to the cutter while...
