Definitions
- the present invention relates to a device for mincing foodstuffs, in particular hackers, with a housing having a shell and a plunger displaceably guided in the housing against the shell and having at least one blade.
- Devices of the type mentioned are known in practice and exist in different embodiments. These devices are often referred to as hackers and are used for crushing food of any kind.
- the food is first placed on the shell. Subsequently, the plunger is moved downwards against the shell by means of the hand, the at least one knife arranged on the plunger effecting a comminution of the food arranged on the dish.
- the plunger is usually spring biased relative to the housing so that it rests in the unactuated state at the upper end of the housing. That is, after a crushing operation by pushing down the plunger it moves automatically due to the spring bias back up and away from the food or food.
- the shell of the housing forms a substantially flat working surface for the knife.
- the knife usually experiences a very high resistance, as the knife almost invades the food along the entire length of its blade.
- the resistance of the food usually decreases, so that a lighter hacking process is possible.
- the chopped food usually accumulates gradually in the edge region of the bottom of the shell, which in turn means that it is often no longer completely or even not reached by the knife.
- the knife often grabs in a further disadvantageous manner on the lower part of the housing.
- the present invention is therefore based on the object of specifying a device for shredding foods of the type mentioned above, in which a safe shredding of the food is realized with structurally simple means.
- the above object is achieved by a device for mincing food with the features of claim 1. Thereafter, the device is configured and further developed such that the shell has a bottom of different depths formed and that the blade is adapted with its cutting edge of the contour of the ground substantially.
- the shell has a bottom of different depths.
- the bottom of the shell has at least one depression.
- the blade with its cutting edge is essentially adapted to the contour of the ground.
- this ensures that the knife, in particular in the region of the depression of the base, securely engages with the food to be comminuted and slipping into the depression or with the wood chips.
- unwanted movement of the wood chips is avoided in areas of the soil in which the knife can no longer be effectively or not at all brought into engagement with the wood chips.
- a centering of the knife in the shell is achieved. As a result, an undesirable strip of the knife is avoided at the bottom of the housing.
- the first chopping process is also facilitated, since the knife, which in its contour substantially matches the recess of the base, does not engage with its entire cutting edge length simultaneously with the food during this first chopping process.
- the intervention takes place from the center of the depression to the edge of the depression along the food time-offset. After each chopping process, the wood chips usually fall in the direction of the center of the recess. This ultimately leads to a targeted and effective crushing process when hacking.
- the floor could be concave.
- a safe accumulation of the wood chips to the center of the concave depression and thus ensures a secure engagement position for the knife during the Hackvortician.
- the bottom could be convex.
- a convex formation results in accumulation of the chips in the edge region of the soil, which is bordered by the outer edge of the shell.
- a quasi annular depression area could be formed between the outer edge of the shell and the convexity of the soil, in which the chopping of the wood chips takes place. Dodge the chips in areas where engagement with the knife is not possible, is avoided.
- the bottom could be spherical or spherical segment-shaped.
- Such a configuration may relate on the one hand to a concave and on the other hand to a convex design of the soil.
- the profile of the floor is defined by a visually appealing and structurally simple design.
- the bottom could be truncated cone-shaped or cone-shaped. Again, this particular embodiment may refer to both concave and convex formations of the soil. Due to the symmetry of such a design a simple and visually appealing design of the soil is possible.
- the blade of the blade could have a profiling adapted to a concave or convex bottom.
- the blade of the blade could have a profiling adapted to a spherical or spherical section or to a frusto-conical or conical bottom. The profiling of the blade of the blade is ultimately defined by the configuration of the bottom of the shell.
- the knife could be formed quasi-complementary to the ground.
- the bottom could be formed substantially rotationally symmetrical with respect to the displacement axis of the plunger.
- a rotation of the plunger and thus of the knife during the hackvortician or from Hackvorgang to Winvorgang is possible.
- the knife could be designed for rotation or rotation about the displacement axis of the plunger for this purpose. This ensures a particularly safe shredding of the wood chips.
- the knife could be designed such that the covering of the soil by the knife - in terms of its rotation or rotation - is greater in an edge region of the bottom than in a central region.
- Such a design of the knife is particularly useful in a convex configuration of the soil, for example. When creating a depression in the edge region of the soil.
- the knife could also be designed such that the covering of the bottom by the knife - in terms of its rotation or rotation - in a central region of the bottom is greater than in an edge region.
- Such a configuration is particularly suitable for a concave bottom with a concavity in the central region of the soil.
- the covering could increase or decrease continuously from the center of the floor to the outside and / or continuously.
- the knife With regard to the configuration of the knife, various designs could be realized. In a particularly simple knife, the knife could be integrally formed. This simplifies the manufacture of the device, since only one knife must be installed. With regard to a particularly flexible design of the knife assembly and thus with regard to a particularly effective comminution of the wood chips, the knife could have a plurality of individual blades. Depending on the requirement, the individual knives could be fastened at different positions on the plunger.
- the device according to the invention can be used quite generally in the field of cutting and / or separating devices. Finally, the device according to the invention could be a universal chipper with an improved function.

- FIG. 4 shows a schematic illustration of a covering scheme for a complete rotation of a knife through 360 °.
- FIG. 1 shows a perspective exploded view of a first embodiment of a device according to the invention for chopping up food in the form of a hacker.
- the hacker has a housing 1 with a shell 2. Furthermore, the hacker has in the housing 1 against the shell 2 slidably guided and at least one blade 3 having plunger 4.
- the shell 2 has a bottom of different depths formed 5 and the blade 3 with its cutting edge 6 of the contour of the bottom 5 is substantially adapted.
- the plunger 4 is displaceable along a displacement axis 7.
- the cutting edge 6 of the blade 3 has a profiling adapted to the concave bottom 5.
- the knife is integral and quasi wave-shaped.
- the bottom 5 is substantially rotationally symmetrical with respect to the displacement axis 7 of the plunger 4.
- the blade 3 is designed to rotate about the displacement axis 7 of the plunger 4.
- the bottom 5 is formed substantially spherical.
- FIG. 2 shows a schematic side view, in a longitudinal section and in a cross section of the embodiment of Fig. 1.
- the spherical concave configuration of the bottom 5 is particularly well recognizable.
- the wave-shaped design of the blade 3 with its cutting edge 6 can be seen particularly clearly in the cross-sectional representation.
- FIG. 3 shows, in a schematic and sectional representation - in part - a knife 3 and a shell 2 of a second embodiment of a device according to the invention for mincing food.
- the bottom 5 of the shell 2 is formed substantially convex in the shape of a truncated cone. Accordingly, the blade 3 is concave with its cutting edge 6 and also frusto-conical.
- the wood chips accumulates during chopping in the edge region of the bottom 5, namely in the depression formed by the bottom 5 and the edge of the shell 2.
- This recess is formed substantially annularly around the displacement axis of the plunger.
- FIG. 4 shows a schematic illustration of a covering scheme for a complete rotation of a knife through 360 °. These are essentially 16 hacking operations, with a rotation of 22.5 ° between each hacking operation.
- This embodiment of the knife which leads to this overlapping scheme, lends itself in particular to the second exemplary embodiment according to FIG. 3. As a result, a particularly safe crushing of the wood chips in the concave edge region of the bottom 5 is achieved.
