Abstract

The juice press has two interconnected levers with dish and pressing mandrel (6). The outer face (7) of the mandrel has one or more protrusions (8) which run cross-wise to the folding inversion movement between the dish (5) and pressing mandrel. The protrusions are formed as ring beads (9) spaced from each other in the axial direction of the mandrel and running completely or in part round the circumference of the mandreL.

Description

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

DE 34 14 873 A1 describes a hand press for juicing Known fruits. This juicer has two on one End connected via a joint lever and a Holding cup and a press mandrel. The latter are each on egg Nem lever arranged so that the receptacle by a Closing movement of the lever can be put over the mandrel. Wei terhin is provided in the known juicer that the Press mandrel is formed by a perforated arched bottom. The holes in the vaulted floor are described in DE 34 14 873 A1 vertical, d. H. disclosed parallel to the everting movement and can also be provided with a gauze mesh.

However, this juicer has several disadvantages. The holes in the vaulted floor can be squeezed out by solid particles juicing fruits are blocked so that the squeezed Juice can run out insufficiently or not at all. This can also lead to the juice obtained during pressing is squeezed out of the juicer or even out splashes. Especially the latter leads in the processing of z. B. Citrus fruits continue to increase their juice due to the acidity a risk of injury if the juice gets into the eyes of the user or the user injects. That only through his holes interrupted vaulted floor leaves only an unsatisfactory juice booty as the pulp is compressed and pressed together is pushed and forms a resilient mass that the pressing force  dampens. Furthermore, the known juicer is only complex and difficult to clean, because ge in the holes during the squeezing process squeezed pulp, especially after it has dried or the fruit kernels are difficult to remove by hand can or can be.

Numerous juicers are also known from practice a mandrel with ribs running in its longitudinal direction contain. With these juicers, one must be squeezed out Fruit held very firmly with one hand on the mandrel pressed and at the same time around the common axis of fruit and mandrel are rotated. Since the same time Juicer needs to be held with the other hand With such a press, juice extraction is not only very difficult rare, but also very difficult. Furthermore, the cleaning Such juicers usually difficult. Furthermore, the Handling such juicers is actually always too dirty hands. It is also possible to squeeze fruit e.g. B. directly not possible over a pot or bowl.

There are also a variety of electrically powered fruit presses sen. However, these are very expensive, require a lot of space and are usually also difficult to clean. Even with such Fruit press is a pressing of fruit e.g. B. directly above a pot or a bowl is not possible.

The known from the prior art embodiments of Juicers all lead to the fact that as possible on their way application is dispensed with and finished juice products are used. It turns on health, taste and cost increasingly prefer freshly squeezed juices ceases.

The invention aims to provide an easy to use and effec tive juicer to create.  

This goal is achieved with a juicer according to claim 1 enough.

The invention is thus based on a juicer with two each at one end levers connected by a hinge and a holding shell and a press mandrel, each on one Levers are arranged so that the receptacle by a Closing movement of the lever can be put over the mandrel. in the As part of the development of this juicer according to the invention it is provided that the press mandrel has an outer surface, those with at least one at least approximately or partially transverse to the everting movement between the receiving shell and mandrel ongoing survey is provided.

A further development of the invention is based on the fact that Outer surface of the mandrel a plurality of at least approximately herd or partially transverse to the everting movement between recording shell and mandrel extending surveys is provided.

The ridges or bumps on the outer surface of the press thorns form when the receptacle and the last are pressed together terem to squeeze out a fruit contained in between Abutment, which presses into the pulp and secondly, by pressing the fruit onto the mandrel with the help the receptacle on the inside of the fruit through its fruit meat runs parallel to the pressing direction and thereby largely releases the juice contained.

Furthermore, the juice or fruit press according to the invention easy to clean. Pulp or pulp fibers, that after opening the press and, if necessary, removing it the squeezed in particular fruit half still on the press thorn remains, can be easily washed off with a water jet will. This is still possible even if the fruit meat residues are already dried. Through the Ausgestal tion with the elevations in the circumferential direction of the mandrel namely effectively prevents z. B. pulp fibers  of citrus or e.g. B. mangoes or other long-fiber Fruits with pulp devoured in holes, as in the known fruit press according to DE 34 14 873 A1 the case is. When cleaning by hand, the juice according to the invention press also against the manual known from practice Rotary presses are advantageous because the hot cleaning water when Holding the mandrel cannot run over your hands, and on the one hand, because the juicer according to the invention or its corresponding part can be easily held on the lever.

Finally, in the juicer according to the invention in Ge in contrast to the known fruit press according to DE 34 14 873 A1 there is no blockage that could impair functionality.

According to a preferred development of the invention, the Elevations formed as annular beads, the whole of the mandrel or include intermittently and axially direction of the mandrel are spaced apart. Preferential three ring beads are provided.

An alternative embodiment provides that the surveys as spiral rib that is formed continuously or with interruptions circumferentially around the mandrel.

Another way to train the increases or Elevations is that they are formed as projections and regularly or irregularly distributed on the outer surface the mandrel are arranged.

Preferably, the mandrel is dome-shaped to a good pressing effect in appropriately shaped fruit halves to ensure.

If the mandrel is in one piece with its associated lever is formed, is advantageously a special enables simple and therefore inexpensive production.  

The advantages of easy cleaning and easy removal alternate damaged or alternative parts united achieved that the receptacle on their assigned Lever via a particularly releasable compensating joint is brought.

A dome-shaped design of the receptacle ensures a good and safe intake of appropriately shaped fruit halves.

If the freshly squeezed juice does not ver can or should be needed, or if a targeted or Dosed dispensing is required, a juice can be beneficial gutter can be used, the mandrel on his Base surrounds.

The latter version is particularly simple and inexpensive set by the lever assigned to the mandrel and the Juice collection channels are formed in one piece. It can na naturally also the mandrel itself into this one lumpy training to be involved.

A targeted dispensing of squeezed juice is in advantageously assigned by the juice collecting channel Juice dispensers, preferably a Pourer included.

If the joint connecting the two levers is at or close to the juice drainage channel is arranged, a particularly com compact and therefore easy to use and space-saving design created.

In order to juice between the holder and the mandrel flesh pressed out in the area of the To keep pressing forces, it is advantageous if the recording peel one of the juice collection channels and adapt to it te extension. Such an extension can  bell-shaped apron that is conical from the receiving shell protrudes from the free edge.

According to a further development of the invention, the Lever shell-carrying levers in the area of the receptacle these are shaped around so that those connecting the levers Free ends of the levers facing away from the joint close to one another lie when the receiving tray is at least substantially above the mandrel is put over. This ensures that the Juicer according to the invention be easily with one hand can be used. Furthermore, the juicer can be aground keep this type light and safe, even during the press force is applied with the holding hand. The level of The base of the press mandrel can namely in or at least close to the bracket formed by the free ends of the levers be laid so that a slight pivoting of the Juicer or tremor of the pressing hand only to one ge just as slight movement of the mandrel base and possibly the Juice trap leads. In contrast to that lies with the free ends of the levers formed holding plane at a juice press according to DE 34 14 873 A1 in the area of the free end the mandrel so that its length acts as a lever, so to speak due to the swiveling or trembling movements when pressing by hand be amplified and the probabilities caused by it speed and the effects of a spill is increased.

He can hold the juicer according to the invention lighter and safer that the lever connecting joint facing away free ends of the levers each Have grip training. The handles are preferably applications integrally formed with their respective lever. A An alternative to this are handle designs that are based on their particular needs leverage are attached.

Preferred materials for the levers, the cradle and / or the press mandrel and / or the juice catcher, if applicable Aluminum or plastic, the parts mentioned at least  partially consist of it. Another advantageous criterion order for the parts of the juicer specified above The invention is that these parts from dishwasher resistant materials.

Cleaning the entire juicer and replacing whose individual parts will be easier if the lever on which they connecting joint are detachable.

To adapt to different sizes and / or shapes To enable fruit or fruit halves is also from Advantage if at least two press mandrels are provided by which at least one as an attachment to the other mandrel is formed or optionally with the associated lever are connectable. This can be used, for example, to pre-version will be seen on a smaller and / or thinner one Basic mandrel a larger and / or thicker mandrel attachment is bar, so that even smaller fruits with the same juicer can be processed. It is advantageous that be riding on the outer surface of the base mandrel according to the invention Surveys are provided, since these, as it were, about ra acting holders of the mandrel attachment on the base mandrel can, in each of the above Forms of the surveys or increases.

It can also be provided that the receiving shell holding and / or Has centering devices, in particular dor are designed like a nen. Such a thorn in the middle of the The inside of the holder is sufficient for an increased hold tion of a fruit half used in the latter. Instead of Dor Nen or the like can also serrations z. B. at the free edge of the recording mesh bowl may be provided. Another possibility is in from the free edge of the receptacle completely or partially to de their center-running ribs, which are just like teeth Squeezing one half of the fruit or fruit in support the holder.  

As already stated in connection with the mandrel and explained, can alternatively or additionally be provided be that at least two receiving trays are provided by which at least one as an insert in the other admission shell is formed or optionally with the associated Lever are connectable.

The pairings of the receiving shell and the press are preferred thorn sized on halves of lemon or small orange gene, especially blood oranges.

Further advantageous and preferred embodiments of the Erfin dung arise from the dependent claims and their Combinations.

To further clarify the invention is as follows merely by way of example a description of an embodiment game specified, with reference to the accompanying drawing is taken in the

Fig. 1 is a perspective view of a juicer in ge schlossenem state,

Fig. 2 shows a perspective view of a juicer in the opened state, and

Fig. 3 shows a longitudinal section through the closed juicer according to the marking III-III in Fig. 1.

In the figures of the drawing, the same or similar and same or similar parts and components throughout provided with the same reference numerals, so that for the Specialist even without a concrete description of each of the figures the relationships are clear. Also allows it the realistic representation in the figures the subject man, also parts not separately marked with reference numerals and features can be easily extracted from it.  

In Figs. 1 to 3 an embodiment of a juice press 1 is shown in perspective. The juicer 1 contains two levers 2 and 3 , which are connected to each other via a joint 4 , and a receiving shell 5 and a pressing mandrel 6 , which are each arranged on a lever 2 or 3 so that the receiving shell 5 by a closing movement of the Lever 2 , 3 can be placed over the press mandrel 6 to assume the closed position, which can be seen in FIG. 1 and shown in section in FIG. 3.

In Fig. 2, however, the juicer 1 is shown in a geöffne th state in which a fruit half, such as a lemon or orange half, but also a mango half or halves of other fruits or vegetables can be placed in the receiving shell 5 , whereby the cut side of the fruit lies to the opening of the receptacle 5 . Without limitation, however, an entire fruit can also be inserted, for example. B. A kiwi or the like. It also does not matter whether fruits intended for use with the juicer 1 are already peeled, or whether they are inserted together with the bowl into the receiving bowl 5 .

After e.g. B. a lemon half was placed in the receptacle 5 , which is sized and shaped accordingly, the lever 2 is folded towards the lever 3 , whereby the receptacle 5 moves towards the mandrel 6 , in such a way that it over the latter fits and can be turned over, but with the fruit half inserted in between.

The mandrel 6 has an outer surface 7 , which is provided with a plurality of at least approximately or partially transverse to the everting movement between the receiving shell 5 and mandrel 6 Erhebun conditions 8 . In the version shown, the elevations 8 are formed as annular beads 9 , which completely embrace the mandrel 6 . There are three annular beads 9 in the illustrated embodiment, which are spaced apart in the axial direction A of the press mandrel 6 . Instead of completely umlau fender annular beads 9 can also be provided with interruptions in the circumferential direction of the mandrel 6 .

Not shown separately, but nonetheless easily understandable are further versions of the design of the elevations or elevations 8 . For example, such elevations 8 can be formed by a spiral rib (not shown), which runs continuously or with interruptions around the mandrel 6 . Although it is in the nature of a spiral that it is not aligned in the circumferential course exactly at right angles to the axis direction A of the mandrel 6 , this is also not necessary. It is only important that the elevations 8 in their chosen form form an abutment against the pressing movement when the juice press 1 is closed , ie when the receptacle 5 is slipped over the mandrel 6 with the interposed fruit. For this purpose, it is sufficient if the elevations 8 , which, as indicated, can also be formed by a single spiral rib (not shown), at least approximately or partially transverse to the everting movement between the receiving shell 5 and pressing mandrel 6 .

Further alternatives for the configuration of the elevations 8 are projections (not shown) on the outer surface 7 of the press mandrel 6 . Such projections can be arranged in the form of a regular or irregular pattern distributed on the outer surface 7 of the mandrel 6 .

A spiral design and / or circumferential interruptions of the elevations 8 can or can make it easier for the squeezed juice to run out between the nested and the fruit half or fruit between the pressing bowl 5 and mandrel 6 .

As the figures make clear, the mandrel 6 is formed kuppelför shaped and in the present embodiment is integrally formed with its associated lever 3 . The receiving shell 5 is also dome-shaped and is attached to its associated lever 2 via a releasable compensating joint 10 . With this compensating joint 10 , the overturning of the receptacle 5 over the mandrel 6 is facilitated, since the relative movement of the receptacle 5 and mandrel 6 when moving the two levers 2 and 3 along an arc segment which passes through the distance from the receptacle 5 and mandrel 6 is formed by the joint 4 of the two levers 2 , 3 . It should be noted that, however, even without the compensating joint 10 by appropriate dimensions and Ge arrangements of the receptacle 5 and mandrel 6 a proper function of the juicer 1 when closing the receptacle 5 and mandrel 6 is guaranteed.

As can be seen from the figures, the mandrel 6 has a base 11 , via which it is connected to its associated lever 3 . In the area of its base 11 , the press mandrel 6 is surrounded by a juice collecting channel 12 . In the embodiment presented here, the mandrel 6 , the lever 3 assigned to it and the juice collecting channel 12 are formed in one piece and are made of a plastic which is dishwasher-resistant. An alternative to the material mentioned is e.g. B. aluminum. The same material provisions apply to the other lever 2 and the receiving shell 5 .

It can be seen in particular in FIGS . 1 and 2 that the juice collecting channel 12 has juice dispensing devices 13 in the form of a spout 14 . The juice dispensers 13 can also contain a spout or spout or the like.

The juice collection channel 12 , like the receiving shell 5 and the pressing mandrel 6, is circular or of circular cross section. As a result, in the embodiment of the juicer 1 shown in the drawing and described here, the spout 14 and the joint 4 connecting the two levers 2 and 3 , which is arranged on or at least close to the juice collecting channel 12 , are spaced 90 ° apart, and the continuation of the juice trap 12 in the form of the lever 3 lies exactly opposite the joint 4 , that is to say it also has a spout of 90 ° from the spout 14 . As a result, both the pressing together of the receptacle 5 and the press mandrel 6 and the pouring out of the fruit juice obtained are very simple.

Especially Figs. 2 and 3 clearly show an extension 15 which mounted the receiving tray 5 at the open end 16, and thus the juice collecting channel faces 12, at least when the juice press 1 is closed. The extension 15 is also adapted to the shape and size of the juice collection channel 12 . In terms of shape, the extension 15 protrudes conically from the free edge 17 of the receiving tray 5 , ie it forms a bell-shaped expansion of the receiving tray 5 .

From the drawing it can also be seen that the receiving shell 5 on the compensating joint 10 carrying lever 2 in the loading area 5 is formed in an arc around this, so that the lever 2 and 3 connecting joint 4 facing free ends 18 and 19 of the levers 2 and 3 are close to each other when the receiving shell 5 is at least essentially placed over the press mandrel 6 , as shown in FIGS . 1 and 3. Furthermore, the free ends 18 and 19 of the levers 2 and 3 each have a handle configuration 20 and 21 , which are formed integrally with their respective levers 2 and 3 . Alternatively, separate Griffausbil training could be provided, which are then attached to their respective levers 2 and 3 .

Both the lever 2 and 3 connecting joint 4 , as well as the compensating joint 10 is detachable, so that the entire juice press 1 can be easily dismantled.

In order to be able to process fruits of different sizes, can also be provided without this separately in the drawing is shown that at least two mandrels are provided  are, of which at least one is an essay on the other Press mandrel is formed or alternatively with the assigned th lever can be connected. Likewise, several on Take trays are provided, of which at least one is used as Use is formed in the other receptacle or which can optionally be connected to the assigned lever The measures required for this are for the subject man easily understandable even without drawing examples Lich. This also applies to holding and / or centering devices conditions provided in the receptacle and z. B. thorny can be trained.

Further training opportunities result directly from the illustrations shown in the drawing, all for a person skilled in the art from modifications which are readily recognizable and substitutions are encompassed by the present invention. Furthermore, the disclosure content is that stated at the beginning DE 34 14 873 A1 by reference in its entirety herein added, so that also removable features in combination nation with the present invention to the scope of the latter belong.
