Description

The invention relates to a kitchen appliance according to the preamble of claim 1.

Kitchen machines are versatile multi-purpose devices that are used to prepare meals in kitchens. Kitchen machines can regularly have agitators and / or heating devices.

So reveals the DE 10 2015 121 827 A1 a beverage preparation device, namely a coffee machine, with a housing and several feet, which together define an installation level, for setting up the beverage preparation device on a surface. The device has at least one sliding foot with a sliding surface which, when the beverage preparation device stands up on the feet, is spaced in the vertical direction both from the underside of the housing and from the installation level and by tilting around a tilting axis and lifting at least one of the feet from the ground to the sliding Moving can be brought into contact with the substrate.

The DE 20 2015 100 846 U1 discloses a support device for supporting an object on a base with at least one sliding foot which is arranged on the underside of the base plate to support movement of the support device on the base and at least one stuffing foot which is attached to the underside of the base plate to prevent movement of the support device the base is arranged.

During their intended use, the kitchen machines typically stand on level surfaces, such as kitchen worktops. For this purpose, the kitchen machines have feet that give them a secure hold. The feet are therefore often designed in such a way that they prevent the kitchen appliance from slipping on typically used surfaces.

In this way, the feet of the food processor give the food processor a secure footing, but they also prevent the food processor from being moved easily on the base.

In situations in which it is desired to change the position of the food processor on its base, it must therefore be lifted. On the one hand, this requires a lot of effort because of the weight of the food processor; on the other hand, lifting the food processor can mean a risk of accidents if, for example, there are hot liquids in the food processor. In practice, however, it is often desired to be able to change the position of the kitchen appliance in a simple manner, for example in order to be able to use the area of the base released by the kitchen appliance for other purposes.

The invention is therefore based on the object of showing a kitchen appliance of the type described above, which can be moved in a simple manner on the base and yet has a secure stand.

The object is achieved by a food processor with a displacement aid with the features of the independent claim. The features of the dependent claims relate to advantageous embodiments.

The kitchen machine described has a displacement aid to enable the kitchen machine to slide and / or roll on a flat surface. To simplify the language, only the term “slide” is used in the following for “slide and / or roll”. The sliding of the kitchen machine on the flat surface is made possible by the fact that the sliding aid of the kitchen machine with a sliding element and / or rolling element - to simplify the language, only the term "sliding element" for "sliding element and / or rolling element" is used in the following - on the surface when the food processor is tilted by lifting it on one side. It is possible for the displacement aid to have a plurality of sliding elements via which part of the weight of the kitchen appliance can be introduced into the base.

Tilting is to be understood in particular as a rotating movement of the kitchen appliance about a horizontal axis. This horizontal axis can be fixed by two feet. In order to bring about the tilting over these two feet, the food processor then only has to be lifted slightly on a side facing away from the two feet over which the food processor is to be tilted. The sliding element or the plurality of sliding elements is then located in relation to the tilting axis opposite the area or the side of the kitchen appliance from which it is lifted.

For the lifting, which is necessary to bring about the tilting of the food processor, only a fraction of the force has to be applied that would be necessary to lift the food processor. This is due to the fact that only part of the weight of the food processor has to be absorbed by lifting, while the rest of the weight continues to be introduced into the base either by the feet and / or the sliding element or the plurality of sliding elements. To this At least part of the weight, which is introduced into the base via its feet when the kitchen appliance is used as intended, is introduced into the base via the sliding element or elements. However, as a result of this force, there is much less friction between the sliding element and the base than would arise between the feet and the base if the feet were to absorb this part of the weight of the food processor.

If the weight of the food processor that is not absorbed by the lifting has then - at least to a sufficient extent - been shifted from the feet of the food processor to the sliding element or the plurality of sliding elements, the food processor can be moved easily on the base.

It can be sufficient that the food processor is tilted so far that a sufficient part of the weight of the food processor is no longer introduced via the feet and thus can no longer contribute to the creation of frictional forces between the feet and the base. However, it is also possible that the food processor is tilted so far that the weight force - at least insofar as it is introduced into the base - is introduced into the base exclusively via the sliding element or the sliding elements. In this case, all feet may lose contact with the base when the food processor is tilted.

At the moment when the tilting movement of the kitchen machine leads to part of the weight of the kitchen machine being shifted from the feet to the sliding element or the plurality of sliding elements, the tilting axis also shifts from the feet to the sliding element or to the Sliding elements. As a result of this displacement of the tilting axis, the lever ratios change when the food processor is lifted, which changes the weight force to be absorbed by the lifting. In other words, when lifting, a noticeable resistance arises at the moment when the weight is shifted from the feet to the sliding element or the sliding elements. The user of the food processor has noticeable haptic feedback that the food processor has been tilted far enough to achieve maximum gliding ability.

The displacement aid has a fastening element or a plurality of fastening elements with which the displacement aid is fastened to the kitchen appliance. The fastening element is preferably designed in such a way that it can interact with a certain type of kitchen appliance. The fastening element can for example be designed as a projection. It can be designed to engage in a suitable receptacle in the kitchen appliance. The receptacle for the fastening element can be located on the floor of the food processor. The displacement aid can then be attached, in particular, to an area of the kitchen appliance where the displacement aid does not interfere with the aesthetic impression of the kitchen appliance.

The projection that forms the fastening element can be molded onto the displacement aid. It is possible to design the displacement aid as an injection molded part. In this case, it is possible to form the fastening element with an injection molding process during the production of the displacement aid. The or a material of the displacement aid can be plastic.

The receptacle for the fastening element can be an indentation in the outer contour of the kitchen appliance, which originally served a different purpose. In particular, openings and / or depressions that have been provided in the kitchen appliance primarily for a different purpose can be used to interact with the fastening element or the fastening elements. For example, depressions that serve to accommodate a fastening element, such as a screw, can be used. Such recesses for receiving screws can be found, for example, on “Thermomix®” kitchen machines.

The displacement aid can be attached to the food processor in a non-positive manner. For this purpose, the fastening element can in particular be designed in such a way that it can undergo elastic deformation in order to establish the force-locking connection. For example, a fastening element designed as a projection can have a recess, such as a slot, which divides the projection into two separate areas. These can then, for example, be bent elastically towards one another in order to generate an outwardly directed clamping force as a reaction force. By means of this clamping force, the fastening element can be clamped in a recess in order to securely fasten the displacement aid to a food processor.

Such an attachment has the advantage that it is reversible, i. H. the displacement aid can be removed from the food processor and attached to it again. This can be advantageous, for example, for cleaning, repair and / or maintenance purposes.

The sliding element or the plurality of sliding elements can be used as intended Use of the food processor on the base may be objected to by the base in such a way that the sliding element or the plurality of sliding elements is spaced from the base in such a way that the sliding element can be brought into contact with the base by tilting the food processor by a defined angle. In this case, it is ensured that the kitchen appliance rests exclusively on its feet when used as intended, so that it has maximum stability. The defined angle can be at least 0.1 °, in particular at least 1 ° and / or at most 10 °, in particular at most 45 °. The food processor is particularly easy to use in practice at this angle.

In this context, the distance between the sliding element and the base can be at least 0.1 mm, in particular at least 1 mm and / or at most 10 mm, in particular at most 5 mm. In the case of typical kitchen machines, these distances allow the kitchen machine to be easily handled when tilting and moving it.

In the simplest case, the sliding element can be molded onto the displacement aid. It can be designed as a projection. It can also be an area of the displacement aid which is intended to interact with the base in order to enable the sliding function. However, it is also possible that the sliding element is a separate element that is attached to the displacement aid. This offers the possibility of making the sliding element from a different material than the area of the sliding aid to which the respective sliding element is attached. In this way, a material with particularly favorable sliding properties, such as polytetrafluoroethylene (PTFE), can be selected for the sliding element. Alternatively and / or in addition, the sliding element can have a coating that promotes the sliding properties, for example made of polytetrafluoroethylene (PTFE).

The displacement aid can be arranged in the area of the rear of the kitchen appliance on the kitchen appliance. This arrangement has the advantage that the food processor can be lifted from its front side. The front of the kitchen appliance is more easily accessible than the back of the kitchen appliance when it is typically used as intended, so the handling of the kitchen appliance is made easier by this type of arrangement of the displacement aid.

One advantage of the displacement aid described is that it can be attached to a kitchen appliance at a later date. This makes it possible to retrofit an existing kitchen appliance with a displacement aid of the type described. In this context, the displacement aid can be designed to match an existing kitchen appliance. This relates in particular to their dimensions and / or the arrangement of the sliding element or the plurality of sliding elements and / or the fastening element or the plurality of fastening elements.

Further practical embodiments and advantages of the invention are described below in connection with the drawings. Show it:

• 1 a view of the underside of a kitchen appliance according to the prior art,
• 2 a view of the underside of a food processor with a displacement aid attached to the food processor,
• 3 a view of a sliding aid with visible sliding elements,
• 4th a view of a displacement aid with visible fastening elements,
• 5 a schematic representation of a kitchen appliance in its intended use position with its feet on a base,
• 6th a schematic representation of the food processor 5 during the tipping process,
• 7th a schematic representation of the food processor 5 in the tilted state.

In 1 is an example of a food processor 1 shown according to the state of the art. As in the example shown, this can be a "Thermomix" ® type kitchen appliance.

The food processor 1 can, as in the example shown, recordings on its bottom 2 , for example two recordings as shown 2 , in the form of depressions. In the food processor shown as an example 1 these recordings are available anyway, since they were originally supposed to perform a different technical function. These recordings 2 can be used to assist in moving 3 on the food processor 1 to be fixed firmly.

The move aid 3 can be at the bottom of the food processor 1 attached. The move aid 3 as in the example shown, two fasteners 4th exhibit. The fastening elements shown by way of example 4th show a gap 5 on which the respective fastener 4th separates into two spaced areas. Will the fasteners 4th , which as in the example shown as molded projections of the Shifting aid 3 can be designed in the recordings 2 are introduced through the gap 5 separate areas of the fasteners 4th bent towards each other. In this way you generate an outwardly directed clamping force as a reaction force with which the displacement aid 3 frictionally on the underside of the food processor 1 is attached.

As in particular in 2 is shown, an edge area 6th the shifting aid 3 to the outer contour of the food processor 1 be adjusted. This adapted contour results in a visually homogeneous transition between the displacement aid 3 and the housing of the food processor 1 . This creates an advantageous visual impression.

The shifting aid can also be used 3 as in the example shown, an opening 7th exhibit. Such an opening 7th allows access to areas of the food processor 1 that would otherwise be used by the shifting aid 3 would be covered. This can be useful, for example, to prevent a ventilation grille from being moved by the sliding aid 3 is covered. Likewise, for example, an outlet opening that the outlet from in the food processor 1 spilled liquids or in the food processor 1 crumbs from the food processor 1 should allow with such an opening 7th be kept open.

The move aid 3 can be like the example shifting aid 3 be designed flat. It can - like the example in particular in the 3 and 4th Moving aid to be recognized - two sliding elements 8th exhibit. The two sliding elements 8th can on one of the fasteners 4th facing away from the shifting aid 3 be arranged.

The sliding elements 8th can for example be made of polytetrafluoroethylene (PTFE).

How the food processor works 1 with the shifting aid 3 goes out of the 5 to 7th emerged. There is the lower part of a food processor 1 shown schematically. The move aid 3 is there in the back area 9 the food processor 1 at the bottom of the food processor 1 attached. The backside 9 is turned away from a front 10 the food processor 1 . At the front 10 it is the side of the food processor 1 that is intended to be used when using the food processor 1 of the people who use the food processor 1 used to be facing. Typically, kitchen machines have 1 in the area of their front 10 Control elements or the like, as they can be reached there particularly easily.

In their in 5 the position of use shown rests the food processor 1 on their feet 11 and 12th . The food processor 1 can - like the food processor shown as an example - two front feet 11 and two rear feet 12th exhibit.

The exemplary shifting aid 3 is designed and attached to the food processor 1 arranged that the sliding elements 8th a distance to the base 13th have on the food processor 1 in their position of use with their feet 11 and 12th stands.

Will the food processor 1 at their front 10 raised, so define the rear feet 12th a tilt axis 14th to which the food processor 1 performs a tilting movement.

When a defined angle is reached by the tilting movement, the in 6th presented situation. The sliding elements 8th come into contact with the substrate 13th and thus begin part of the weight of the food processor 1 on the pad 13th to support. The weight can be increased by further lifting the front 10 so far from the rear feet 12th on the sliding elements 8th shift that the feet 12th finally the contact to the document 13th to lose. This situation is in the 7th shown. The tilt axis around which the food processor is displaced 1 performs their movement by the rear feet 12th defined tilt axis 14th to that by the sliding elements 8th defined tilt axis 15th .

By shifting the tilt axis, the lever changes with that when lifting the front 10 the tilting movement of the food processor 1 is effected. The person who runs the food processor 1 at their front 10 lifts, so feels a change in when lifting the front 10 Part of the weight of the food processor to be overcome 1 . This gives the user haptic feedback, which he can use to tell when the rear feet are on 12th the food processor 1 are completely relieved and removed from the pad 13th take off.

When the rear feet 12th the contact to the document 13th In the case of the example shown, lose is the maximum due to the shifting aid 3 achievable lubricity of the food processor 1 reached as the feet 12th the food processor 1 can no longer generate sliding friction. The user thus notices when the point has been reached at which the front should be lifted further 10 no longer required and moving the food processor 1 on the pad 13th is possible with a minimal frictional resistance.

The features of the invention disclosed in the present description, in the drawings and in the claims can be essential both individually and in any combination for the implementation of the invention in its various embodiments. The invention is not restricted to the embodiments described. It can be varied within the scope of the claims and taking into account the knowledge of the competent person skilled in the art.
