Description

The present invention relates to a kitchen appliance for cutting into slices or slices of products, such as vegetables, fruits, and the like, having a body, a guide surface for reciprocating movement of the cut product along it, a knife, which for cutting the product is offset with respect to the guide surface, which allows you to cut a slice or slice from the cut product when it moves along the guide surface in the direction of cutting towards the knife, with the magnitude of the offset between OOWM and the guide surface is defined by the thickness of the cut pieces or slices, and a removable insert for changing the thicknesses of cut pieces or slices.

A kitchen appliance of this type is known, for example, from DE 29821132 U1, EP 0306017 and DE 8909068 U1.

Such kitchen appliances are also commonly referred to as kitchen or manual vegetable slicers. For slicing, for example, cucumbers, the vegetable slicer is usually held over a bowl or other similar container and, by reciprocating the cucumber, separate slices are successively cut from it. These slices fall through the gap between the knife and the guide surface into the bowl.

The guide surface is often also called the lead surface. In turn, it usually adjoins the knife when viewed in the cutting direction, i.e. in the direction in which the cut product moves towards the knife, another guide surface, which is also called the discharge surface.

The knife is usually located transverse to the cutting direction. So, for example, it can be located perpendicular to the direction of cutting or at a slight angle to it. The most optimal are V-shaped knives, formed by a pair of obliquely arranged blades converging wedge-shaped approximately in the center.

A kitchen appliance can be made of metal, but its body is more often made of plastic.

From the aforementioned publication DE 29821132 U1, a kitchen appliance is known in which two side parts forming a frame structure are connected integrally with the upper guide plate. In addition, in such lateral parts forming the frame structure, there are grooves located at different levels in which the lower guide plate is inserted.

DE 19827077 A1 describes a food grinding apparatus having a main plate and a removable chopping insert that slides laterally into an opening provided for this purpose. The chopping insert is made of plastic and has a transverse knife on the upper side. In the cutting direction, in front of the knife, there is a supply guide that can be rotated on a film hinge and which is held in each of several angular positions by means of a movable adjusting lever.

In addition, in the known vegetable slicer with a V-shaped knife for adjusting the thickness of the sliced slices, the insert forming the lower guide surface and pushed into the vegetable slicer in the cutting direction can be replaced or turned over, thereby changing the thickness of the sliced slices.

From WO 95/24995, a vegetable cutter for cutting products into cubes is known, having a supply surface and a parallel discharge surface, on the leading edge of which there is a V-shaped knife. In the cutting direction, in front of and behind the knife, one row of vertical knives spaced from each other in the transverse direction is provided. If the material being cut is rotated 90 ° between successive cutting processes, then using this vegetable cutter, the product can be cut into cubes. At the same time, it is not possible to vary the sizes of such cubes.

From the publication DE 8909068 U1 indicated at the beginning of the description, a wafer cutter (a device for cutting wafer sheets) is known having a body and an insert in the form of a sliding plate. In the mounting space formed in the housing for such an extension plate, a support plate with a continuous surface is located. On such a support plate there are many recesses. An appropriate number of downward facing protrusions is provided on the underside of the drawer. In the cutting direction, the extension plate can be fixed in the installation space in two different positions. In the first of these provisions, the protrusions enter the recesses. In the second position, the protrusions are adjacent to the base plate. By squeezing the sliding plate from the recesses and then displacing it or moving it in the cutting direction, the thickness of the sliced slices can be reduced.

In addition, from the above-mentioned publication EP 0 306 017 A2, a vegetable cutter with a body and an insert is known. This insert can be pushed into the housing in the cutting direction. The insert has two plate elements with an adjustable distance between them. According to one of the options, these plate elements can be screwed to one another. According to another embodiment, a wedge is inserted between the plate elements. In both cases, the distance between the plate elements can be changed in a direction perpendicular to the cutting direction.

The basis of the present invention was the task of improving the kitchen appliance, which would allow a simple way to change the thickness of sliced slices or pieces.

With regard to the kitchen appliance of the type indicated at the beginning of the description, this problem is solved according to the first embodiment of the invention due to the fact that in order to change the thickness of the cut pieces or slices, the insert in the position inserted into the housing is generally installed in this housing with the possibility of movement in it and with the possibility of fixing in different positions in this case.

Accordingly, the kitchen appliance according to the invention consists of a small number of individual parts. In addition, it is possible to easily change the thickness of sliced slices or pieces. Moreover, to change the thickness of sliced slices or slices, first of all, there is no need to replace or remove the insert and then reinsert it in a different position.

To change the thickness of the sliced pieces or slices, it is most preferable that the insert in the position inserted into the housing be installed with the possibility of being practically parallel to the cutting direction of the permutation and with the possibility of fixing in the housing in various positions occupied by it as a result of the specified parallel permutation.

Due to the parallel displacement or rearrangement of the insert, firstly, for any thickness of sliced slices or slices, a constantly high quality of cutting of the product is ensured, since the installation angle between the guide surface and the knife remains almost unchanged and is mainly 0 °. Secondly, in this embodiment, from a structural point of view, it is comparatively simple in general to ensure the mobility of the insert in the state inserted into the housing and its fixation in various positions.

The possibility of parallel displacement or rearrangement of the insert can be provided in various ways, for example using a hinged parallelogram.

However, it is more preferable to provide between the housing and the insert a parallel guide with at least two inclined guide sections, which are arranged so that the insert is displaced in the first direction forcibly accompanied by its displacement in the direction perpendicular to the first direction.

In this case, it is preferable that the first direction lies in the main plane of the body and, for example, in a vegetable cutter with a V-shaped knife, coincides with the direction of cutting. For kitchen appliances with a straight knife, this first direction can also be parallel to the blade of the knife.

With regard to the kitchen appliance of the type indicated at the beginning of the description, the object of the invention is solved according to the second embodiment due to the fact that the insert is movable in the cutting direction relative to the installation space in the housing, while in the specified installation space under the insert and / or on this the insert is provided with inclined guide sections which, for adjusting the thickness of the cut pieces or slices, are provided when moving the insert in the direction cutting, its forced movement in the direction perpendicular to the specified direction of cutting.

The kitchen appliance made in accordance with the second embodiment is highly reliable and consists of a small number of parts. To control the thickness of sliced slices or slices, the insert must be moved in the cutting direction relative to the installation space, while the inclined guide sections provide for the forced conversion of the longitudinal movement of the insert into its “lifting” movement, i.e. provide a change in the distance (gap) between the guide surface and the knife.

In this case, the change in the longitudinal distance between the guide surface and the knife in the cutting direction caused by such a movement should be taken into account. However, it was found that such a change in the longitudinal distance in practice is negligible.

At the same time, the inclined guide sections make it possible in a relatively simple way to ensure almost complete parallelism between the guide surface and the surface of the knife at any specified thickness of sliced slices or pieces. Due to this, during the cutting process, it is possible to avoid crowding out of the cut product, and from the product itself, regardless of the established thickness of the sliced slices or slices, uninterrupted cutting of slices of uniform thickness with a smooth and even cut surface is ensured.

In contrast, in the prior art solutions, in general, attempts have been made to keep the longitudinal distance between the end edge of the guide surface and the knife blade opposite to it even if the thickness of the sliced slices or pieces is changed by parallel shifting or rearranging the insert. So, for example, according to the aforementioned publication EP 0306017 A2, it was proposed to insert in three parts so that the distance between two opposed plate elements could be changed using a wedge between them due to the relative movement of these plate elements exactly perpendicular to the cutting direction.

However, according to the publication DE 8909068 U1 also indicated at the beginning of the description for changing the thickness of sliced slices or pieces, it is possible to fix the drawer in two axially different positions in the housing. However, the scheme for moving the drawer provided for this known kitchen appliance for its rearrangement and adjustment to a different thickness of the sliced slices is relatively impractical. This is due to the fact that in order to reduce the thickness of sliced slices or slices, the extension plate must first be raised perpendicular to the cutting direction to extract its protrusions from the recesses. For this purpose, a corresponding hole is provided in the housing. After this, the extension plate needs to be displaced in the axial direction, coinciding with the direction of cutting, before it is installed in the second fixed position. In addition, another drawback of this design is that the choice of the thickness of the slicing or slicing is essentially limited to only two, and not a large number of values.

However, the solutions proposed in accordance with the first and second embodiments of the invention make it possible to adjust the thickness of the sliced pieces or slices by more than two values, for example, three, four or even more values. In some cases, such regulation of the thickness of the sliced slices is even stepless.

Thus, the proposed in accordance with the second embodiment, the solution also allows you to completely solve the problem posed in the invention.

Most preferably, the mounting space for the insert is formed in the housing. In this case, the kitchen appliance can be made consisting essentially of only two separate parts, one of which is the body, and the other is the insert (or several different removable inserts).

In another embodiment, the installation space for the insert can be formed in the adapter, fixed in the housing in the working position. A particular advantage of this option is primarily the possibility of retrofitting with a similar adapter the existing kitchen appliances, especially the well-known vegetable cutters with a V-shaped knife.

As already mentioned above, in a known vegetable slicer with a V-shaped knife, the thickness of the sliced slices or slices can be changed by replacing or turning the insert. In contrast, when using an adapter in the body of a known vegetable cutter with a V-shaped knife, first, instead of inserting, you must insert such an adapter. In this case, a prefabricated structure consisting of a housing and an adapter has the same or almost the same functionality as a structure in which the installation space for the insert is formed directly in the housing.

In this case, the adapter is most preferably performed with the possibility of its sliding into the housing in the direction of cutting and fixing in the working position. In accordance with this, the adapter itself is fixed in the housing in one single position - the working position. Moreover, due to the provided possibility to slide the adapter in the cutting direction, it can be used primarily in combination with the well-known vegetable cutters with a V-shaped knife mentioned above.

According to another preferred embodiment, it is proposed to insert with the ability to move in the cutting direction relative to the installation space when the adapter is locked in position. In this case, the implementation of the first and second embodiments of the present invention is provided. In other words, to control the thickness of the sliced or sliced slices, the insert can be moved in the cutting direction in the position inserted into the housing.

According to an alternative preferred embodiment, the insert is movable relative to the mounting space when the adapter is removed from the operating position, and is not movable relative to this mounting space when the adapter is locked in the working position. In this alternative embodiment, to change the thickness of the sliced or sliced slices, the insert can be axially displaced relative to the adapter only when the adapter is removed from the housing. As soon as the adapter together with the insert fixed in it in a certain position is installed in the working position, the adjustment function in the cutting direction is blocked.

If the first of the above alternative options allows you to quickly and easily change the thickness of the sliced slices or pieces, then the second alternative option allows you to increase the stability (rigidity) of the whole structure.

It is further preferred that the angle of inclination of the inclined guide sections relative to the guide surface is from 5 to 50 °, preferably from 5 to 30 °. In this case, with a relatively small stroke of the insert in the first direction (respectively, in the cutting direction), it becomes possible to adjust the thickness of the sliced slices or pieces in a relatively wide range.

According to another preferred embodiment, the inclined guide sections are formed by inclined surfaces on the housing on which the mating insert elements are supported. It should be noted that inclined guide sections can, in principle, also be provided on the insert, and mating elements on the housing. However, the advantage associated with the placement of the inclined guide surfaces on the housing is the ability to simplify the design of the insert. Since several inserts are often provided for use with one cabinet, this solution simplifies the design of the entire kitchen appliance as a whole.

In this case, it is most preferable to perform at least two inclined guide sections on opposite sides of the housing, and these mating elements are in the form of pins protruding from the sides of the insert. In this case, it is possible to obtain a compact parallel guide.

It is further preferable to position at least one central inclined guide section below the insert, forming a support for the insert. As a result, it is possible to prevent the deflection of the insert even when a large force is applied to it from above.

Moreover, it is more preferable to place the specified Central inclined guide section next to the knife. Due to this, the amount of displacement (gap) between the knife and the guide surface (i.e., the thickness of the sliced slices or pieces) remains constant regardless of the force applied to the guide surface.

In accordance with another embodiment, to change the thickness of the cut pieces or slices, it is proposed to perform a rotary insert, for which the insert in the position inserted into the body is mounted to rotate about an axis offset from the knife, and can be fixed in various angular positions in this body. In this case, a fixture of a particularly simple construction can be used to fix the insert in the housing.

In general, it is preferable to provide for the stepless adjustment of the thickness of the cut pieces or slices. For this purpose, it is preferable to provide a clamping device for fixing the insert in any of the positions occupied by it in the housing.

The possibility of stepless regulation of the thickness of sliced pieces or slices allows you to use a kitchen appliance for cutting products into pieces of various sizes.

According to an alternative embodiment, the possibility of stepwise or discrete regulation of the thickness of the cut pieces or slices is provided. Moreover, for fixing the insert in one of several positions in the housing, it is preferable to provide a locking device. Such a locking device is relatively easy to obtain primarily in the manufacture of the housing and / or insert of plastic.

In addition, it is generally preferable to provide for the possibility of moving the insert into a position in which the edge of the guide surface opposite the knife is at the same level with the knife blade or above this level. In this (inoperative) position, which is a safe position, the possibility of accidentally touching the knife blade and cutting it is excluded. In this case, the knife blade is closed by the edge of the guide surface.

It is further preferable to provide at the insert on its guide surface a row of vertical knives oriented transversely to the cutting direction. The presence of such vertical knives allows a simple way to cut the product not only into slices, but also into straws.

In this case, it is most preferable to provide for the possibility of moving the insert into a position in which the upper edges of the row of knives protrude above the upper side of the "main" knife by an amount that is at least equal to the thickness of the sliced pieces or slices. In this case, when moving the cut product in the cutting direction, such vertical knives cut it in the longitudinal direction from the lower, not yet cut side. If, before the subsequent cutting process, the product being cut into pieces is rotated 90 ° or close to this value, then the cut strips will be crosswise cut across them with vertical knives and then cut with the “main” knife, resulting in pieces in the form of rectangular parallelepipeds.

Thus, using the kitchen appliance according to the invention, using a conventional insert, the product can be cut into slices, and when using an insert with a number of vertical knives, the product can be cut into either thicker strips or smaller cubes.

It is obvious that the design features discussed above and described in more detail below can be used not only in the combination indicated in each case, but also in any other combinations or even separately, without departing from the scope of the invention. Below the invention is described in more detail on the example of some variants of its implementation with reference to the accompanying drawings, which show:

Figure 1 shows a first embodiment of a kitchen appliance (vegetable slicer) according to the invention, indicated by a common position 10. Such a kitchen appliance 10 generally has an approximately rectangular body 12 on which a knife 14 with a cutting edge 16 is fixed.

The knife 14 is made in the form of a metal plate of approximately rectangular shape and is located perpendicular to the longitudinal axis 18 of the housing 12. Obviously, the knife 14 can also be positioned obliquely to the longitudinal axis 18. In addition, the knife can also be made in the form of a V-shaped knife formed by two separate blades.

In front of the knife 14 is a guide surface 20, which is offset with respect to the knife 14, i.e. somewhat recessed with respect to the level at which the knife is located 14. In the direction of the longitudinal axis 18 on the other side of the knife 14, a discharge surface 22 is provided which is located in the same plane as the upper side of the knife 14. This discharge surface 22 is formed by the upper side of the cross member 23 of the body 12.

The guide surface 20 is formed by the upper side of the removable insert 24. This insert 24 is held in position inserted into the housing 12 between its two longitudinal side walls 28 extending from the cross member 23 parallel to the longitudinal axis 18. In this case, the insert 24 is located between two inner sides facing each other 29 longitudinal side walls 28.

The insert 24 in the position inserted into the housing can be moved along parallel guides perpendicular to the longitudinal axis 18, as schematically indicated by arrow 32. The parallel displacement of the insert 24 relative to the housing 12, and thereby relative to the knife 14 allows you to adjust the thickness of 10 pieces of product cut using a kitchen appliance .

Insert 24 using the schematically depicted clamping device 34 can be fixed in any position adjusted by its rearrangement or displacement along parallel guides, which allows steplessly changing the thickness of the sliced product.

Obviously, the kitchen appliance 10 shown in FIG. 1 is only shown schematically. In this case, the surfaces 22, 20 can be smooth or profiled (structured). In addition, to increase the rigidity of the structure, the longitudinal side walls 28 at their cantilever protruding ends can be interconnected. In addition, the longitudinal side walls 28 may also slightly protrude above the outlet surface 22, forming a kind of sliding support for the holder, with which the cut product is held, or a similar device, which eliminates damage to the knife 14 by such a holder.

When working with the kitchen appliance 10, a chopped product, such as fruit, vegetables, for example a cucumber, is moved back and forth first in the cutting direction 36 approximately parallel to the longitudinal axis 18. When the chopped product is moved along the guide surface 20 to the knife 14 and further towards the outlet surface 22 a slice is cut from the cut product. The cut slice under the influence of its own weight falls down through the gap between the knife 14 and the insert 24 into the container, usually located under the kitchen appliance. With the subsequent reverse movement to the front of the kitchen appliance, the cutting process, when the rest of the cut product passes over the knife 14, does not occur. At the next movement in the cutting direction, a slice is again cut from the product.

Obviously, the knife 14 does not have to have a flat blade. So, for example, the blade of the knife 14 may also have a corrugated or wavy profile.

To change the thickness of the cut pieces or slices, loosen the clamping device 34 and the insert 24, without removing it from the housing 12, is displaced along the parallel guides 32 by the required value parallel to the plane of the knife. After adjusting the thickness of the sliced pieces to the required size, the clamping device 34 is again clamped, thereby fixing the insert 24 in the housing 12.

Figure 2 shows a second embodiment of a kitchen appliance, indicated at 40.

This kitchen appliance 40 is generally similar in design to the kitchen appliance shown in FIG. In this case, the same elements are indicated by the same positions. Only the differences of the design shown in FIG. 2 are discussed in more detail below.

Kitchen appliance 40 has a housing 42. This housing 42, in turn, has a cross member 46, the upper side of which forms a guide surface 20, and two longitudinal side walls 44 extending back from the cross member 46. In addition, a handle 47 is schematically formed on the cross member 46.

Between the longitudinal side walls 44 is an insert 48, the upper side of which forms a discharge surface 22. In addition, a knife 14 is provided on the front edge of the insert 48.

The insert 48 with the knife 14 fixed therein can move relative to the housing 42 along the schematically shown parallel guides 50 approximately parallel to the guide surface 20.

To fix the insert 48 in the housing 42, and in this embodiment, a clamping device 34 is provided.

The principle of operation of the kitchen appliance 40 and its handling are fully consistent with the kitchen appliance 10. However, in the second embodiment, the position of the insert 48 rather than the insert 24 is adjusted to change the thickness of the sliced pieces.

Figure 3 shows a third embodiment of a kitchen appliance according to the invention, indicated at 60.

This kitchen appliance 60 is generally similar in design to the kitchen appliance 10 shown in FIG. 1. In this case, the same elements are denoted by the same reference numerals. Only the differences of the design shown in FIG. 3 are discussed in more detail below.

Instead of insert 24, a fixture 62 is provided for the kitchen fixture 60, which can rotate on the schematically indicated pivot guide 66 about axis 64.

The axis 64 of the rotation of the insert runs approximately parallel to the knife 14 at the end sections of the longitudinal side walls 28.

To stabilize the ends of the longitudinal side walls 28 are interconnected by an element 68, which at the same time can act as a handle.

To change the thickness of the pieces to be cut, the schematically indicated clamping device 34 is loosened. Then, the insert 62 located in the housing 12 is rotated around the axis 64 until the necessary clearance is established between the knife 14 and the adjacent section of the insert 62. After that, the clamping device is clamped again, fixing the insert 62 in the adjusted in this way angular position.

The principle of handling a kitchen appliance 60 for cutting the product into slices with it is completely similar to the kitchen appliance 10. However, in this case, the product to be cut comes into contact with the knife 14 not parallel to it, but, as a rule, at a small angle to it, usually from 1 to 10 °.

Figures 4 and 5 show a preferred embodiment of a kitchen appliance according to the invention, indicated by common reference numeral 80.

This kitchen appliance 80 in its construction basically corresponds to the kitchen appliance 10 shown in FIG. In this case, the same elements are indicated by the same positions. Only the differences from the kitchen appliance 10 are discussed in more detail below.

Kitchen appliance 80 has a housing 81 with two longitudinal side walls 82 and a cross member 84 connecting both of these walls 82.

The surface of the cross member 84 forms a discharge surface 22. A V-shaped knife 86 is located on the edge of the cross member 84 facing the guide surface 20.

Such a V-shaped knife consists of two halves, respectively, of two blades, each of which extends from one of the longitudinal side walls 82 up to the longitudinal axis 18 at an angle to the latter, comprising from about 10 to 70 °, primarily from about 15 to 30 °. As a result, both blades of the knife form an angle between themselves in the range from 30 to 100 °, preferably from 30 to 60 °.

The longitudinal side walls 82 protrude somewhat above the discharge surface 22, as is seen primarily in FIG. Due to this, the holder, known per se, with which the cut product is held, can be moved along the upper sides of the longitudinal side walls 82 as along the guides without damaging the V-shaped knife 86.

The longitudinal side walls 82 extend forward starting from the cross member 84 (that is, towards the cutting direction) and at the end sections are connected by another cross member 87. An insert 88 can be inserted into the space defined by these elements, the upper side of which acts as a guide surface 20.

This insert 88 is generally plate-shaped and on the front side, i.e. on the side facing the V-shaped knife 86, is also approximately V-shaped (wedge-shaped). The top of such a V-shaped insert 88 may be made blunt.

In the inserted position in the housing, the insert 88 can move along two parallel guides 90 provided on opposite longitudinal side walls 82, approximately parallel to the diverting surface 22 (respectively, the V-shaped knife 86). The direction of such a parallel offset of the insert is indicated in FIG. 5 by the bidirectional arrow 91.

Each of the parallel guides 90 has two longitudinally spaced guide grooves 100. Each of these guide grooves 100 has an input guide section 93 extending approximately vertically (in the drawing plane) and an inclined guide section 92. This inclined guide section 92 begins at the lower end of the inlet guide portion 93 and forms an angle 94 with the guide surface 20 from 10 to 50 °, preferably from 15 to 30 °.

On the lateral edges, the insert 88 has two longitudinally spaced guide fingers or pins 96, the outer diameter of which corresponds to the width of the guide grooves 100.

When inserting the insert 88 into the housing 81, the guide pins 96 are inserted from above into the upwardly directed guide grooves 100 and lowered to the bottom of the input guide portion 93. In this position, the insert 88 is offset from the knife 86 by the largest amount, respectively, has the largest clearance relative to it. The insert 88 allows its parallel displacement from this position by moving the guide pins 96 along the corresponding inclined guide sections 92.

The movement of the insert along the inclined guide sections 93 along the longitudinal axis 18, respectively, in the cutting direction 36 is simultaneously accompanied by its forced displacement perpendicular to this direction, i.e. up in the plane of the drawing of figure 5. As a result of this movement, the distance decreases, respectively, the gap between the insert 88 and the knife 86, and thereby the thickness of the cut pieces.

When using the kitchen appliance, considerable force is applied to the insert 88 from above. Therefore, in order to prevent deflection of the insert 88 in the transverse direction, the housing 81 is provided with an additional transverse support 102 located under the V-shaped surface of the V-shaped knife 86, which connects the longitudinal side walls 82 to each other. Such transverse support 102 has at least in the middle part the inclined surface and, therefore, acts as a central inclined guide 102. On the underside of the insert 88, a corresponding support wedge 104 is provided that slides along the central inclined guide 102.

Obviously, the presence of a central inclined guide 102 is optional, and its purpose is to prevent lateral deflection of the relatively thin inserts 88. In order to ensure reliable parallel movement of the insert in another embodiment, it would also be sufficient to provide a central inclined guide 102 and only two opposite ones each of the guides of the groove 100 (and not four, as is the case in the present embodiment). Therefore, in this alternative variant, not shown in the drawings, the insert would be based on three points, which, as is known, is quite sufficient to obtain a stable support.

Position 106 in figure 4 further indicates a series provided on the insert 88 of the vertical knives located with some indent from each other in the transverse direction. Obviously, the presence of such knives located in a row 106 is optional, and some inserts 88 may be provided, and some may be absent.

Position 108 in figure 4 indicates the locking device. In addition to fixing the insert 88 in a certain position relative to the knife 86 with a tightening and releasing clamping device, schematically shown, for example, in FIG. 1, a locking device 108 is provided in this case. Such a locking device 108 is formed by several laterally located in the rear section of the insert 88 grooves 110 spaced from each other in the longitudinal direction, as well as elastically bent, a latch 112 located on one of the longitudinal side walls 82.

In the unloaded state, the latch 112 enters one of the grooves 110 and thus holds the insert 88 in a position fixed relative to the longitudinal extent of the housing 81, and thereby maintains a constant gap between the insert and the knife, the value of which is determined by the position 98 the thickness of the sliced pieces.

To change the thickness of the sliced pieces, the latch 112 is bent outward to the side, as shown schematically in figure 4 by arrow 114. As a result, the latch releases the insert 88, which can therefore be freely moved in the longitudinal direction. After adjusting the thickness of the sliced pieces to the required value, the latch 112 is released again, while the latch slides (latches) into one of the grooves 110, fixing the insert 88 in the housing in the adjusted position.

Such locking with the locking of the latch in the groove is possible only when the guide pins 96 are in the inclined guide sections 92 of the guide grooves. Since the walls of the inclined guide sections 92 do not allow the vertical movement of the guide pins 96 up and down, even the locking device 108, which is so simple in design, always allows the insert 88 to be securely fixed in a certain position relative to the housing 81.

Obviously, the tilt angles 94 of the inclined guide sections 92 and the central inclined guide 102 should preferably be the same. In addition, it is preferable further, as shown in the drawings, to move the insert 88 parallel to the knife 86 and the outlet surface 22. However, in principle, the insert 88 can also be placed with a slight inclination to the knife 86, respectively, to the outlet surface 22 and in such an inclined position to move parallel to to myself.

Shown in figures 4 and 5, the kitchen appliance 80 as a whole is only shown schematically. It is obvious, however, that for the convenience of handling such a kitchen appliance, handles of a corresponding shape, made taking into account the ergonomic requirements, can be provided on it. It is further apparent that the sharp or acute-angled edges or edges present in the structural elements shown in the drawings can in practice be rounded so that the parts of the kitchen fixture 80 can be almost entirely made of plastic by injection molding. Thus, in particular, the housing 81 and / or the insert 88 is preferably made of plastic, and the V-shaped knife 86 is made of steel suitable for this purpose, preferably stainless steel.

If a clamping device is provided instead of the locking device 108, then in this case it is also possible to provide stepless adjustment of the thickness 98 of the cut pieces of the product.

It is also obvious that instead of the inclined guides 92 and 102, it is possible to provide other parallel guides, respectively guides, providing parallel movement of the insert, for example, a guiding mechanism in the form of an articulated parallelogram.

In accordance with another embodiment, not shown in the drawings, the guide grooves 100 can also be made U-shaped in plan view, as a result of which the insert will parallelly move generally not at an angle, but perpendicular to the longitudinal axis 18. In this case, as obviously, other locking devices, preferably clamping devices, should be provided.

According to one of the preferred embodiments shown in FIG. 6, it is possible to push the insert 88 up by such a value that its upper side, i.e. the guide surface 20 is located above the cutting edge of the knife 86. This position, indicated by solid lines in FIG. 6, is the inoperative position of the kitchen appliance 80, into which it can be transferred at the end of work with it and in which it can be placed on the table or stored . In this case, the sharp cutting edge of the knife 86 remains protected. Thus, in this embodiment, protection is provided against a possible cut on the knife blade (the so-called "child protection"). The working position for cutting products into slices of a certain thickness 98 'is indicated by broken lines in FIG. 6.

7 shows another embodiment of the insert 88A, which, unlike the insert 88 shown in FIGS. 4 and 5, with a smooth, respectively even guide surface 22 (which can also be structured or profiled) has several vertically protruding separate knives 120 located with some indentation from each other in the transverse direction. These knives 120 are located approximately according to the pattern indicated by 106 in FIG. 4. Knives 120 protrude above the guide surface 20 by a value such that the products can be cut into slices in two different modes.

In the position of the insert 88A shown in FIG. 7 by solid lines, the upper edges of the knives 120 protrude above the knife 86 by the amount indicated in FIG. 7 by the general position 124. This value 124 is larger than the thickness 98 of the cut pieces provided in the same position. When using the kitchen appliance 80 with the insert 88A installed in the indicated position, the product is first cut by the cutting edges 122 of the knives 120 into a series of parallel strips, which are then cut by the main knife to obtain pieces 98 thick. Moreover, the knives 120 protruding by a value of 124 are also not longitudinally cut cut off part of the cut product. If the cut product is rotated 90 ° before the next cutting process, then the cut product, cut into strips to a certain depth, is then cut with knives 120 transversely to these strips, which are finally cut with a knife 86 in the form of cubes. Before the next cutting process, the product to be cut should again be rotated 90 °, etc. Thus, when the insert is placed in the indicated position, the product can be cut into cubes, respectively, by rectangular parallelepipeds (only if the step between the knives 120 is equal to the thickness of 98 sliced pieces).

In the second position of the insert 88A (designated 88A ′), which is shown in FIG. 7 by a dashed line, the upper edges of the knives 120 are approximately at the level of the cutting edge of the knife 86. In this insert position, the product is cut into strips during each cutting process. In this case, the lower side of the cut product is not cut.

Obviously, in combination with the housing 81, other inserts 88B and the like can be used, which, for example, are equipped with separate knives 120 of lower height and / or with a different pitch between them, which allows you to cut the product into strips and / or cubes of various sizes .

However, the creation of conditions under which the removable insert 88A can be set in such a position that the vertical knives on this insert 88A protrude above the “main knife” 86 so that the product can be cut into cubes or rectangular parallelepipeds, in general, regardless of the mobility of the insert when installed in the housing position should be considered as an independent object of the invention.

Another embodiment of the invention is shown schematically in FIG. In this alternative embodiment, instead of the parallel guides 90, one parallel guide 130 is provided, which instead of the guide grooves 100 is approximately constant over the entire length of their width in the form described below.

The surfaces of these parallel guides 130 are given a certain contour, which is characterized by the presence of two axially spaced support inclined guide sections 132 and two staggered axial spaced guide sections 134 spaced apart from each other in the axial direction.

In this embodiment, an insert 88 (not shown) has on each side not two axially spaced pin guides 96, but four axially spaced pin guides 136. Two of these guide pins are in contact with the support inclined guide sections 132, and two other guide pins 136 are adjacent to the lower side of the persistent inclined guide sections 134.

In this embodiment, an upward or downward movement of such an insert with guide pins 136 is also provided when it is moved in the axial direction, i.e. the insert can always be set to the desired position relative to the housing.

Unlike the parallel guide 90 with relatively narrow guide grooves 100, the parallel guide 130 has larger recesses 138, from which it is much easier to remove dirt. In addition, such large depressions 138 are less prone to clogging with accumulated dirt.

Figures 9-14 show a fifth embodiment of a kitchen appliance according to the invention, indicated at 150.

The operating principle of this kitchen appliance 150 generally corresponds to the operating principle of the kitchen appliances discussed above.

Kitchen appliance 50 has a housing 152 shown in FIGS. 9-11. The housing 152 has two longitudinal lateral walls 154, 156 extending approximately parallel to each other, between which a discharge surface 158 is located. A V-shaped knife 160 is fixed on the leading edge of this discharge surface 158. In this regard, this construction corresponds to the construction of the known V-shaped vegetable slicer. with a knife. The housing 152 also has a mounting space 162 for the removable insert. In this mounting space 162, there is a support plate 164 located between two longitudinal side walls 154, 156. Such a support plate 164 is slightly offset or recessed relative to the discharge surface 158 and is located substantially parallel to it. The support plate 164 has two inclined guide sections 166, 168, which are also V-shaped in accordance with the V-shape of the knife 160. The elevation angle 169 (FIG. 13) of each of the inclined guide sections 166, 168 relative to the support plate 164 is approximately 8 °. At the front end, the support plate 164 has a transverse edge 170 to which a handle portion extending downward is adjacent.

The installation space 162 is laterally limited by the longitudinal side walls 154, 156. The longitudinal side wall 154 has a side wall 172 located on the side of the installation space 162. In the area of this side wall 172 a fixing device 173 is provided for fixing the insert. This locking device 173 has a latch 174 protruding perpendicular to the cutting direction 36. Such a latch 174 formed by the protrusion is made on an elastic bridge or an elastic portion 176 of the side wall 172. Due to this, when the insert is inserted into the housing, the latch 174 formed on the protrusion can be squeezed to the side. Alternative to the lateral arrangement of the locking device 173, a similar locking device can also be integrated into the support plate 164.

The elastic bridge or elastic section 176 is limited by a slot 187 (an oblong hole) in the upper part of the longitudinal side wall 154, and also by a parallel slot 180 (an oblong hole) extending parallel to it in the side wall 172. Said elastic section 176 remains between the two slots 178, 180. .

As schematically shown in FIG. 10, at least one transverse jumper 184 is provided under the support plate 164 located between the vertical side walls 154, 156. The support plate 164 has a V-shaped (wedge-shaped) pointed shape. The cantilevered portion facing the V-shaped blade 160 thus formed is supported by at least one transverse jumper 184 located beneath it. This prevents spring bending downward of this V-shaped portion of the support plate 164 when a force is applied to it from above from the side of the cut product.

As shown in FIGS. 9 and 11, an output edge 186 is adjacent to the inclined guide sections 166, 168. This output edge 186 is located substantially parallel to the support plate 164 and the V-shaped knife 160 of the plane. Such an exit edge 186 forms, when the insert occupies the lowest position (which is described in more detail below), a part of the guide surface for the product being cut.

An insert inserted into the installation space 162 of the housing 152 is shown in FIGS. 12-14 and is indicated at 190.

12, insert 190 is shown in a bottom view. This insert 190 has a base plate 192, which can conditionally be divided into a substantially rectangular portion and a V-shaped pointed portion. The upper side of the insert 190 forming the guide surface 194 is substantially flat. In this case, the insert 190 with all thicknesses 98 of the cut pieces of the product as a whole is located in the installation space 162 so that its guide surface 194 lies in a plane parallel to the plane of the V-shaped knife. The underside 195 of the base plate 192 is aligned with the configuration of the mounting space 162.

In the rear V-shaped pointed portion, the main plate 192 has two wedge-shaped chamfered surfaces 196, 198 on the lower side 195. The location, size and angle of inclination of these chamfered surfaces 196, 187 correspond to similar parameters of the inclined guide sections 166, 168 of the support plate 164 bounding installation space 162.

At the front (left in FIG. 12) end, the base plate 192 has a wedge-shaped thickening 200 with a thickness increasing toward the front end. The angle at the apex of this wedge-shaped thickening corresponds to angle 169.

As shown in FIG. 13, the lower side 195 of the base plate 192 is located along the length L parallel to the guide surface 194. The length L is also shown in FIG. 9.

Obviously, the dimensions and shape of the installation space 162 and the lower side 195 of the main plate 192 are mutually agreed so that the insert 190, when it is in the first position (the largest thickness of the pieces to be cut), is abutted against the base plate 164. The guide surface 164 is located approximately at the level of the output edge 186. The wedge-shaped thickening 200 protrudes somewhat beyond the transverse edge 170 of the support plate 164.

Two opposing longitudinal edges 202 of the insert 190 are parallel to the side walls 172 defining the mounting space 162. On one of these longitudinal edges 202 there are several recesses 204 arranged in a longitudinal direction in a longitudinal direction under the latch. Such recesses 204 are consistent with the shape and dimensions of the protrusion of the latch 174 of the locking device 173.

10 also shows two guide or restriction protrusions 182 protruding inwardly from the side walls 172. Such guide or restriction protrusions 182 provide directional longitudinal movement of the insert when it is inserted into the installation space 162. In addition, these guide or restriction protrusions limit the vertical top the mobility of the insert 190, preventing its installation in an inclined position in the installation space 162.

Insert 190 is pushed into installation space 162 from front to back (from right to left in FIG. 9). In this case, the lateral longitudinal edge 202 elastically presses the latch 174 formed by the protrusion laterally until it slides into the first of the recesses 204. In this position, the guide surface 194, as mentioned above, is approximately at the level of the output edge 186. In this position sliced pieces have the greatest thickness. With further insertion of the insert 190, it is parallel displaced relative to the support plate 164 (and thereby parallel to the plane of the knife). This is due to the fact that with this further insertion of the insert 190 into the installation space 162, firstly, the beveled surfaces 196, 198 slide upward along the inclined guide sections 166, 168. Secondly, the front of the insert 190 rises by the same amount for due to the movement of the wedge-shaped thickening 200 along the transverse edge 170.

As shown by way of example in FIG. 12, the insert 190 may have five recesses 204 under the retainer. Four of these recesses are used to fix the insert in different positions of its guide surface 194 and, therefore, to adjust the thickness of the cut pieces to different values.

When the protrusion formed by the protrusion 174 enters the last of the recesses 204, the guide surface 194 is located approximately at the level of the V-shaped knife 160 or slightly above it, which almost completely eliminates the accidental cut about the V-shaped knife. Thus, this last position corresponds to the inoperative position shown in FIG. 6 for storing the kitchen appliance, or a safe position.

Obviously, in this embodiment, the guide inclined sections, respectively beveled surfaces are made in the form of planar inclined guides, which are adjacent directly to other surfaces of the corresponding elements (housing 152, respectively, insert 190). In general, the kitchen appliance 150 has such a design that allows a simple way to stepwise adjust, respectively change the level of the location of the insert due to its installation in several possible positions (more than two). At the same time, handling such a kitchen appliance presents absolutely no difficulties even for inexperienced users.

In addition, due to the execution of the housing 152 and insert 190 with mainly smooth surfaces, the kitchen appliance as a whole is easy to clean, since the remains of the cut product do not get stuck in small grooves or other recesses and recesses due to their absence.

In the kitchen appliance 150, the installation space 162 for the insert is formed by the housing 152. Thus, the kitchen appliance 150 in the simplest case consists of only two parts. It is obvious, however, that instead of insert 190, it is also possible to use, for example, inserts with transverse knives, i.e. knives mounted transverse to the main knife, as is schematically shown in Fig.7.

On Fig-18 shows a sixth embodiment of the proposed in the invention of the kitchen appliance, indicated by the General position 150 '. This kitchen appliance 150 'in almost all respects corresponds to the kitchen appliance 150 shown in Fig.9-14.

In the kitchen appliance 150 ', the same inserts 190 are used as in the kitchen appliance 150. The kitchen appliance 150' differs from the kitchen appliance 150 in that the housing 152 'is not designed specifically to fit the insert 190 into it, but is designed for installation into it an adapter, which in FIGS. 15-17 is indicated by 210.

The body 152 'may be a conventional body of the prior art vegetable slicer with a V-shaped knife. A case of this type allows you to insert the insert from front to back and set it at the same time in a certain working position. To change the thickness of the sliced pieces, you can either use different inserts, or use one insert in an inverted position.

Instead of such a known insert, an adapter 210 can be inserted into the housing 152 ′ of the kitchen appliance 150 ′ by placing it in a specific operating position. Subsequently, with such a design consisting of a housing 152 and an adapter 210, it is possible to operate in exactly the same way as with the housing 152 described above.

To distinguish between the positions that indicate the corresponding elements of the adapter 210, respectively, of the housing 152 ', an apostrophe is added.

Additionally, in FIG. 18, the numeral 212 indicates the mounting space for the adapter. Sideways in this mounting space 212 there is a guide 214, which are located at the respective side partitions 172. In addition, on the side walls 218 of the mounting space 212 there are provided recesses 216 for the lock, which allows the adapter 210 to be fixed in one of the operating positions.

In addition, in one of the side walls 218, an elastic bridge 220 is formed formed by two parallel slots (oblong holes), which are similar to the slots 178, 180 shown in Fig.9. However, an inwardly facing protrusion is not provided on this resilient web 220.

The adapter 210 has, as shown in FIG. 15, a support plate 164 ', which has a substantially rectangular shape with a V-shaped pointed end. At this V-shaped pointed end, two inclined guide sections 166 ′, 168 ′ are provided which extend into the exit edge 186 ′.

On a rectangular portion of the base plate, two side partitions 172 'are provided, one on each side. An elastic bridge 176 'is made on one of these side partitions 172', on the inner surface of which there is provided an inwardly facing protrusion forming a latch 174 '. Such an elastic jumper 176 'is formed by a slot in the transition section between the support plate 164 and the side wall 172'.

On the upper edge of both side partitions 172 ', there is one guide or restrictive protrusion 182'.

The location of the locking device 173 'is consistent with the location of the elastic bridge 220. Due to this, the insert 150 can be moved in the longitudinal direction to adjust its height position even when the adapter 210 is installed in the working position. In this case, the latch 174 formed by the protrusion on the elastic bridge 176 'is squeezed to the side, which is ensured by the elasticity of the bridge 220.

If the housing 152 'is made without slots, i.e. without an elastic jumper 220, as is the case with conventional vegetable cutters with a V-shaped knife, the axial displacement of the insert 190 relative to the adapter 210 is possible only when the adapter is removed from its working position. In this case, when the adapter is in the working position, the latch 174 'cannot be squeezed to the side.

With this design, the adapter 210 complete with the insert 190 is firmly and stably held in the mounting space 212. However, changing the thickness of the pieces to be cut is a relatively simple operation. To do this, you just need to remove the adapter 210 with the insert 190 from the installation space 212. After that, you can adjust the position of the insert 190 in height by axial movement relative to the adapter 210. Finally, this entire assembly can be inserted back into the installation space 212 in the working position .

Massive parts with smooth surfaces are also involved in the kitchen fixture 152 for adjusting the thickness of the cut pieces, which makes the kitchen fixture 152 generally easy to clean and reliable in operation.

Obviously, the prefabricated structure, consisting of adapter 210 and insert 190, is an individually marketed product that can be sold as an “extra tool” for existing vegetable cutters of known design with a V-shaped knife.

It is further apparent that the preferred embodiments of the kitchen appliance of the invention shown in FIGS. 6-8 can equally be used with kitchen appliances 10, 40, 150, 150 ′. Shown in Fig.6 and 7 options also allow their use in the kitchen fixture 60.
