Description

The invention relates first to a system consisting of a mixing vessel of a food processor and a stirrer in the mixing vessel, wherein the agitator is driven in an electric motor housed in the food processor position of the mixing vessel by means of an electric motor provided in the food processor, via a coupling with a lower side of the Agitator accessible coupling extension of the agitator cooperates.

Systems of the type in question are known, for example. Under the trade name "Vorwerk Thermomix". In this regard, for example, on the DE 102 10 442 A1 directed. In addition, for example, continue on the DE 44 14 823 A1 , The content of these patent applications is hereby incorporated in full into the disclosure of the present invention, also for the purpose of including features of these patent applications in claims of the present invention.

In the operating position of the mixing vessel, d. H. in assignment position of the same in the food processor, in particular to be cooked food in the mixing vessel or recirculating various ingredients by means of the agitator. In addition, such an agitator, in particular when training with or in the form of a knife factory, for crushing, for example, foodstuffs. Further, by means of the electric motor drivable agitator in the mixing vessel and a dough making possible, so in particular by appropriate kneading and circulating the dough and ingredients in the mixing vessel. The agitator remains after removal of the mixing vessel from the food processor usually first in the mixing vessel.

The drive of the agitator in assignment position of the mixing vessel in the food processor takes place in the known solutions according to a clutch driving, including the kitchen engine side provided electric motor by means of a preferably end of a motor shaft arranged coupling receptacle receives the downwardly over the Rührgefäßboden freely projecting coupling extension of the agitator in particular form-fitting manner.

After removal of the mixing vessel from a recording of the food processor may sometimes result in difficulties in emptying the mixing vessel. There may be a jamming of content in the area of the agitator. Tough masses can also hang in the agitator area.

The invention is concerned with the stated problems with the object, the system, as described above, in particular with regard to a removal of masses from the mixing vessel, more particularly with respect to dough or food with viscous and / or plastic consistency to train favorably.

A possible solution of the problem is given according to a first inventive idea in a system, as mentioned above, in which a hand attachable to the coupling extension hand tool is additionally provided, with which the agitator is actuated when taken out of the food processor agitator. The system allows in handling technically favorable manner rotation of the agitator even with a taken out of the recording in the food processor agitator. It can purposefully a complementary rotation, even with low speed, going back and forth, possibly also made shaking. In this way, a removal or emptying of the mixing vessel can also be achieved, in terms of mass, which tend to jam or viscous adhesion to an inner surface of the mixing vessel and in particular of the agitator. Larger parts or sticky, not easily pourable masses, which settle between the agitator and the Rührgefäßboden, by means of the usable hand tool by a targeted rotation of the agitator, for example. With additional hand-engagement in the mass to the solution from the mixing vessel be charged. The hand tool is set for this purpose by the user by hand on the coupling extension of the removed from the food processor mixing vessel for actuation, in particular rotation of the agitator.

The hand tool associated with the system is placed on the mechanical interface of the stirrer coupling exposed on the underside with the stirrer vessel removed. It is designed to fit directly to it. An adjustment or adaptation of the hand tool to the clutch is not required. As part of the system it is always available to the user. By its design is also preferably a self-explanatory instructions for use already given.

The invention further relates to a hand tool.

In view of the known prior art, a technical problem of the invention is seen therein, a hand tool Specify in particular for use in the kitchen area, by means of which an improved use of a kitchen appliance can be achieved.

A possible solution of the problem is given by a relevant inventive idea in that the hand tool is designed for rotating an agitator in a mixing vessel of a food processor, wherein the hand tool forms a receptacle for placement on a side of the mixing vessel provided coupling extension of the agitator, wherein the recording rotatably connected is adapted to rotate with the hand of the user adapted handling surface or by a provided in the hand tool electric motor. According to the proposed embodiment of the hand tool, the user of the food processor is given an aid with which an emptying of the mixing vessel of the food processor can be favorably influenced. With regard to the food processor and the mixing vessel to be arranged there, it is preferably such as described at the beginning of the prior art. Thus, after removal of the mixing vessel from the food processor of the coupling extension of the agitator is so accessible free that the hand tool can be placed accordingly, so on, in particular for non-rotatable coupling with the coupling extension of the agitator. Following rotation of the hand tool, the stirrer is correspondingly entrained in the mixing vessel, whereby any masses or parts fixed between the stirrer and the mixing vessel bottom can be loosened in order to support the complete emptying of the stirring vessel. By selectively rotating the agitator with removed mixing vessel, deviating from the built-in in the kitchen engine (only) possible stirring routine, especially coarse or highly viscous masses, so mainly food, such as dough or puree, from a jamming or clamping be solved with respect to the agitator.

The hand tool further preferably has a handling surface adapted to the user's hand, so that advantageously an ergonomically favorable handling of the hand tool is achieved. By means of such a hand tool, preferably only manual rotary displacement of the agitator in the mixing vessel can be achieved. Alternatively, an electric motor is provided in the hand tool, which rotationally drives the receptacle connected in a rotationally fixed manner, in particular with a motor shaft, so more preferably according to intentional triggering by the user. In such a motorized operation of the agitator by means of the hand tool, the user's hand picks up the counter-moment of the motor arranged in the hand tool. By a certain co-rotating or counter-rotating this additionally the characteristic of the impingement of the agitator can be influenced.

But they can also be in an assignment to only individual features of the claims already mentioned or the other claims or each independently of importance.

The hand tool, possibly also in electromotive drive the recording for the coupling extension, is preferably formed with a Getriebeüber- or -untersetzung. Hereby, the rotation angle, which is given by hand or motor, with respect to the actual rotation of the agitator can be increased or decreased. In particular, a reduction in terms of the possible lower application of force can be essential.

A further embodiment provides, in particular in connection with a hand-operated recording alone, to achieve the desired rotation of the agitator by a movement of the handle in the axial direction of the axis of rotation of the agitator. For this purpose, a helical coil can be provided which has a large pitch. In the handle of the tool, a corresponding nut may be formed, which in substantially purely axial operation, the rotation of the helical coil, then, for example, is firmly connected to the receptacle for the coupling extension causes. Such drives are, for example, also known in toy gyros or screwdrivers or drill hand tools. The rotation of the receptacle for the rotary drive of the agitator can in each case be predetermined in a certain direction. Alternatively, a switchover possibility with regard to the two possible directions of rotation can also be provided. In addition, it can also be provided that in the course of an actuation, both a rotation in a first direction and a subsequent thereto in a second, opposite direction results.

This recording is particularly adapted in terms of their cross-sectional configuration to the corresponding cross-sectional configuration of the agitator-side coupling extension. Thus, the receptacle is preferably designed as an internal polygon, in particular in the form of an inner hexagon (Torxausformung). Further preferably, the receptacle has an arbitrary cross-sectional configuration, in particular for positive engagement with the coupling extension of the agitator, so on, for example, a square, Hexagon, slot or Phillips cross-sectional configuration. In a further embodiment, the receptacle is formed with respect to the cooperating with the coupling extension part of the training of the coupling extension, for example, as a polygonal socket accordingly as an external polygon. In addition, a purely frictional connection between recording and coupling extension is preferred. In any case, the coupling between the hand tool and the agitator, which can be produced if necessary with a removed mixing vessel, can preferably be manufactured or canceled without the need for a further tool. It is preferred in this regard further that the receptacle is formed in a cylindrical portion of the hand tool.

The rotatably connected to the recording handling surface, in particular when forming the hand tool as a manually operable tool, is preferably a lever or a handle, for example in the manner of a screwdriver handle. In a preferred embodiment, the handling surface forms a plate portion which extends perpendicular to the cylinder portion. This plate section is for preferred adaptation to the user's hand further in particular edge-circumferential coarse-tooth knurled, whereby an ergonomic handling of the hand tool is achieved.

In particular, in the embodiment of the hand tool with an electric motor, the hand tool has a rechargeable accumulator for the electric motor. Alternatively or additionally, a constant power supply of the electric motor can be provided, so for example. According to connecting the hand tool via a power cord to the household power grid.
