In this case the flap on the blending attachment is then no longer required. This arrangement therefore provides that as soon as the flap is operated by hand, the switch steps for permanent operation are switched off, i.e., before the blending attachment is inserted into the coupling device of the hand mixer.Īs the flap is displaceable against the force of a spring, the opening of the coupling device is automatically closed again by this flap when the blending attachment is extracted, whereupon the switch releases the switch steps for permanent operation.
The locally separated connecting positions of the blending attachment and the dough hook or beater make it possible that the coupling device provided for the blending attachment is externally accessible via an additional opening provided in the motor casing, and that the opening can be closed by a flap under the force of a spring and that during the insertion of the tool into the opening the flap must be displaced against the force of a spring.ĭuring the displacement of the flap it actuates an actuating element of the electric switch. This safety device can be achieved in a particularly simple way if the tool is provided with a stop which displaces an actuating element provided on the electric switch during the insertion of the tool into the coupling device. This measure ensures that before the tool is connected with the drive unit of the hand mixer, the switch step for permanent operation is separated from the electric circuit and the motor switches itself off, which ensures that injuries caused during the insertion of the tool in the operating hand mixer are prevented. This embodiment is particularly simple and can be manufactured with a minimum of effort and expense. Naturally, the invention can also be employed, if so desired, when a dough hook, etc. Microsoft word 2016 1529 downloadĪccording to the invention it is therefore possible to switch on the switch steps for permanent operation during the use of the hand mixer with a knife-like tool, but the drive motor will not be activated. In this way it is ensured that unpleasant injuries to the user are prevented, because the instant release of the hand from the switch instantly interrupts the drive of the hand mixer. It is only possible to switch on the hand mixer through the switch step for short-time operation, i.e., as long as the switch for short-time operation is held in its short-time position, the hand mixer remains switched on.Īs soon as the switch for short-time operation is released by the user, said switch returns to the switch-off position or zero position.

In the event of manual activation of the switch step for short-time operation, however, the electric motor will remain connected with the power supply. If during the permanent operation of the hand mixer it is placed on the working table for a short period by the user, it is possible that, for example, during the permanent operation of the hand mixer a user reaches towards the freely accessible rotating knives, which might lead to severe injuries.

If the switch step for the permanent operation is selected, the knife provided at the free end of the fast blending attachment rotates until the switch in the switch step for permanent operation is brought back to the O-position. When using the Krups hand mixer in connection with Krups fast blending attachment, it is possible to manually switch on both the switch steps for permanent operation as well as short-time operation.
Krups Parts Manual Actuation OfĪ coupling device is used for holding and driving various insertable tools, and an interlock ensures that after the insertion of the blending attachment or other knife-like tool into the coupling device, the electromotor remains separated from the power supply despite the activation of the switch steps (I, II, III) for permanent operation of the electromotor, whereas the electromotor remains connected with the power supply during the manual actuation of the switch step (IL) for short-time operation of the electromotor.
