Description

Kitchen appliance for cutting goods, especially fruit, vegetables or potatoes, into slices

The invention relates to a kitchen appliance for cutting goods, in particular fruit, vegetables or potatoes, into slices, with a base plate which has two contact surfaces located on an upper side of the base plate, between which at least one knife running essentially transversely to the direction of movement of the goods to be cut is arranged.

The direction of movement of the item to be cut should essentially correspond to the longitudinal dimension of the generally rectangular kitchen appliance.

With the kitchen appliances described at the beginning, fruit, vegetables or potatoes can be processed into a variety of products, for example in the form of schnitzels, depending on the design of the knife. While it is not a problem to cut the product to be cut into relatively fine pieces, it is difficult to obtain a manageable and stable kitchen appliance with which, for example, potatoes can be cut into slices. Since this requires a relatively large exposed cutting edge, the knife often becomes unstable and the cutting result is not satisfactory.

A solution known from the state of the art, which is also available on the market, provides for a cutting edge to be formed in a metal plate, whereby the length of the cutting edge is limited to only a part of the corresponding dimension of the contact surface, so that precise guidance of the material to be cut is required.

It is the object of the present invention to design a kitchen appliance for cutting goods, in particular fruit, vegetables or potatoes, into slices in such a way that a good cutting result is achieved with a maximum cutting area.

According to the invention, in the area of the at least one knife, a web is provided which is connected to the base plate and on which the respective knife is held. This allows the knife to be supported over its entire length, which essentially corresponds to the width of a contact surface, so that undesirable deformations of the cutting edges can no longer occur. It is therefore possible

BOEHMEKE "& BOEHmJrT ⁵ ": ""'

the entire width of the contact surface can be used for cutting.

The knife is advantageously made from a metal strip, which allows very sharp cutting edges to be worked.

According to a preferred embodiment of the invention, the knife has at least one opening through which the material of the web extends. The knife is thus anchored to the web.

Although in principle smooth slices can also be cut, the invention offers the possibility of designing the cutting edge of the knife in a variety of ways in order to obtain cutting material with different profiles. One example would be to design the cutting edge of the knife as a wavy profile.

In order to increase the working speed, the knife should have two cutting edges facing each other in the direction of movement of the material to be cut, so that a cut is also made when the material to be cut is returned.

The stability of the arrangement can be increased if an area of the knife between the cutting edges is lowered to the underside of the base plate. Preferably, at least one opening should then be located in this lowered area of the knife. The web can then be designed in such a way that it at least partially encloses the knife, or more precisely, that the web at least partially encloses the knife in the lowered area.

BOEHMERT & BCfElMEftT

In particular in a configuration as described above, but also in other embodiments, the web can be designed to run at least partially on the upper side of the knife.

There is no need to accept any loss of cutting area if the part of the web that runs on the top of the knife is contoured to match the cutting edge(s) of the knife. This is particularly true of the embodiment of the invention in which the knife has the recessed area mentioned above.

The material to be cut is guided optimally if the contact surfaces, at least in the area adjacent to the knife(s), have a profile that essentially corresponds to the contour of the cutting edge(s).

The invention will be explained in more detail below with reference to the accompanying drawing. It shows:

Figure 1 is a plan view of a kitchen appliance according to the present invention; and

Figure 2 is a longitudinal sectional view in the plane of symmetry of the device according to Figure l.

The kitchen appliance shown in plan view in Figure 1 has a base plate 2, on the visible side of which, which is to be referred to as the top of the kitchen appliance, has two contact surfaces 4, 6. Between these contact surfaces 4, 6 a knife 20 is arranged in such a way that when the product to be cut is guided in the direction of the arrows A, the knife lies transversely to this direction. The

BOEHMERT & BCTEBMERT :*': *:

Base plate 2 has a handle 8 adjacent to the contact surface 4.

As can be seen better in Figure 2, the knife 20 is provided with two cutting edges 24, 26, each of which faces the adjacent contact surface 4 or 6. The cutting edges 24, 26 are located above the respective contact surface 4, 6. Between the cutting edges 24, 26 there is a region 28 which is lowered towards the underside of the base plate 2 and in which a plurality of openings 22 are provided.

The knife 20 is held by a web 10 which runs transversely above and below the knife 20 and holds and supports it. The web 10 is connected to the base plate 2 at the edge areas, as shown in Figure 1. The material of the web extends through the openings 22, so that a practically inseparable anchoring of the knife band 20 and the web is achieved.

On the top of the knife 20, the web is contoured in such a way that an essentially smooth and step-free contour is created over the area of the knife 20, which corresponds to the contour of each of the cutting edges 24, 26, in the example shown a wave profile. The resulting cut material then has this wave profile. In order to obtain a corresponding contour of the cut material on the top and bottom as the cutting process continues, the contact surfaces 4, 6 are provided with grooves 12, which can be seen particularly well in Figure 1, the width and pitch of which correspond to the wave profile of the cutting edges 24 and 26.
