Description:
FIELD OF THE INVENTION 
       [0001]    Manually operated devices for processing, in particular comminuting vegetables and other foodstuffs have been known for years. A device with a crank drive, in which two rigid blades, which project in opposite directions at right angles, are arranged on a central shaft which projects perpendicularly into an approximately circular-cylindrical container for cut material, is described in U.S. Pat. No. 6,035,771. After the material to be comminuted has been filled into the container, the latter is placed on a work surface and the top part with the crank drive is placed on it. In use, i.e. in particular when turning the crank, the device must be held in place with the second hand, or respectively pressed against the work surface. When operating the device, the user does not receive any information regarding the progress of the work. The degree of comminution of the foodstuffs to be processed can only be detected by removing the top part and looking directly into the container for material to be processed. It is not possible to judge from the outside whether still further revolutions of the crank are necessary. 
         [0002]    A small, approximately cylindrical manually operated device is known from WO 2004/073474, which is hand-held for operation. A central shaft with two blades, which project at right angles in opposite directions, is driven by means of the repeated rotation of a circular drive mechanism in relation to the coaxially arranged container with the material to be processed. Since the device must be almost completely enclosed by the hands of the user, the structural size is extremely limited. The material to be processed—for example an onion—must be cut into quarters for filling, since otherwise there is no room for it in the container for the material to be processed. For achieving a satisfactory chopping result, it is necessary to rotate the drive element 40 to 60 times alternatingly in opposite directions in relation to the remaining parts of the device. The rotating movement of the drive unit in relation to the container is transmitted by a gear to the shaft with the cutters. Since the blades are provided with cutting edges on both sides, it is possible to cut in both directions by a directed reversal of the turning direction of the shaft. Even though the device has a container made of a transparent material and should therefore allow a view of the interior, i.e. of the material to be processed, in actual use it has been shown that in the course of, or after, the cutting operation no clear view of the interior is possible. If fresh vegetables or herbs are cut, the entire container is smudged by juice within a short time, so that no conclusion regarding the degree of cutting is possible anymore from the outside. The user must again open the device and check the work process directly in the container. 
         [0003]    Other devices for processing vegetables and the like, which have an electrical drive mechanism and various control programs, are known. For example, US 2002/0176320 shows a mixer, which has predefined programs for motor control, which are shown on a display. Thus, the user is provided with the possibility of pre-selecting a suitable program in accordance with the material to be processed. After the start of the selected program the respective control commands are executed and the motor drives the cutting unit, and the time, direction and number of revolutions of the rotating movement are preprogrammed. No report regarding the result of cutting is provided. Therefore the user has no possibility of terminating the microprocessor-controlled program when a desired degree of cutting has been reached. Moreover, in connection with such devices the dependence on external energy sources is disadvantageous, as well as the required electrical cord for energy supply which, on the one hand, limits the work location and, on the other, unnecessarily requires work space. 
       BACKGROUND OF THE INVENTION 
       [0004]    The object of the invention is based on making available a device in accordance with the invention which does not have the above mentioned disadvantages. It is intended to show a device which permits the control of the processing degree without being dependent on either an external energy supply or batteries or the like. Furthermore, manufacture and assembly of the device should be cost-efficient and, besides cutting or chopping, the device should be usable for further processing steps of foodstuffs, and in general should be simple, dependable and comfortable to operate and to clean. 
         [0005]    This object is attained by means of a device having the characteristics of claim  1 . 
         [0006]    Further advantageous embodiments of the device in accordance with the invention ensue from the dependent claims. 
         [0007]    It is an essential characteristic of the device in accordance with the invention that a processing degree indicator directly shows the user the actual work progress by means of an easily visible display. The processing degree indicator is autonomous, i.e. independent from an external voltage supply wherein, in accordance with preferred embodiments, a generator unit internal to the device sees to it that no batteries or similar voltage sources are required. 
         [0008]    It is essential for understanding the invention that in connection with the novel devices no previously stored program is executed, instead the actually performed number of processing movements, i.e. for example the actually performed number of revolutions of the drive unit and/or the processing unit, is detected and displayed. This direct reporting, together with the manual drive method, makes it possible for the user to stop the work process at any time, or to continue it. 
         [0009]    The user is provided with information regarding the work progress, for example the degree of comminution achieved, without having to open the device for this or to make a direct check of the material to be processed in the processing container.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0019]    A first embodiment of the device  1  for processing foodstuffs in accordance with the invention is represented in axial longitudinal section in  FIG. 1 . The represented device is a cutting device and is comprised of a cutting unit  60 , which is not shown in section. The device  1 , which is embodied substantially rotation-symmetrical around a central shaft  4 , has a top part  2 , which is comprised of a circular, substantially flat base  21  with a curved cover  20  placed on it. Essential parts of a drive mechanism  10 , as well as a device for displaying the processing degree, called processing degree indicator in what follows, are housed between the cover  20  and the base  21 . The top part  2  can be placed in a positive and/or non-positive manner on a lower part  3  which, in the present case, comprises a bowl-shaped container  30  for material to be cut. The container  30  for material to be cut is preferably made of a transparent or semi-transparent plastic material approved for foodstuffs and includes a bottom  31  with a central, upward oriented bearing journal  33  and a lateral wall  32  with a plurality of vertical swirling ribs  34 , evenly distributed over the circumference. On its underside the cutting unit  60  is provided with a central bearing opening, by means of which it can be plugged onto the bearing journal  33  in the container  30  for material to be cut. The cutting unit  60  in accordance with the represented embodiment is substantially constituted by a cutter shaft  67 , from which three blades  61 ,  62 ,  63  and two deflectors  50 ,  51  protrude as the operative means. A drive cam  69  at the top, in the exemplary embodiment represented a cam with a hexagonal exterior, of the cutting unit  60  engages a corresponding reception opening  71  of an engagement member  23  of the drive mechanism  10  in a positive manner, so that the torque can be transferred from the engagement member  23  of the drive mechanism  10  to the cutting unit. The engaging member  23  is seated in the center of the base  21  rotatably, but not axially displaceable, with low friction and sealed against the base  21 . In this way the cutter shaft  67  with the operative means  50 ,  51 ,  61 ,  62 ,  63  is dependably seated at the top and the bottom, and during the operation can absorb without problems the forces introduced into the operative means, in the present example the cutters  61 ,  62 ,  63  and the deflectors  50 ,  51 , even at high rpm, without being deflected out of their axial position. 
         [0020]    In accordance with the instant invention, the rotating movement of the operative means is generated by a cord pull mechanism. As represented in  FIGS. 1 and 2 , with the pull cord  70  wound up, the handle  11  comes to rest in a recess  5  of the cover  20 . The pull cord  70  fastened to it is conducted under low friction to a winder or cord roller  12  attached to the interior of the top part  2  and is wound up on it. A spring housing  7  is arranged concentrically above the winder  12  on a bearing journal  9 , which extends downward from the cover  20 . The length of the cord pull  70  has been selected to be 400 to 750 mm, preferably 600 mm, in such a way that, with a corresponding diameter of the winder  12 , the winder  12  rotates over the entire diameter 3 to 6 times, preferably 4 to 5 times, per pull on the pull cord  70  (until its complete unwinding). In the exemplary embodiment of  FIGS. 1 and 2 , a device  1  with a drive mechanism  10  with gearing is represented, in which the driveshaft  8  is arranged eccentrically on the inside of the cover. 
         [0021]    The winder  12  is preferably manufactured in one piece with the spring housing  7  located above it and a hollow wheel, also called drive wheel  14 , located below it. The drive wheel  14 , arranged eccentrically in relation to the central shaft  4 , is open at the bottom and provided with internal teeth. The internal teeth are respectively only sketched in  FIGS. 1 and 2 . It is in an operative connection with external teeth of an axial journal  17 , which is seated concentrically in respect to the central shaft  4  in the top part  2 . The gear ratio in the exemplary embodiment represented is 1:1.8, while a gear ratio of 1:1.5 up to 1:4 has proven itself to be advantageous. 
         [0022]    The axial journal  17  is a part of a secondary drive unit, comprised of the axial journal  17 , rotor disk  18  and bearing bushing  19 , and whose axis of rotation coincides with the central shaft  4  of the device  1 . The axial journal  17  is concentrically seated on a rotor disk  18 , which has clamping means for receiving a magnetic ring  90 . In the exemplary embodiment represented, the clamping means have a peripheral groove. An interior area of the magnetic ring is clampingly held in the peripheral groove of the rotor disk  18  by means of a clamping ring  80 , so that the larger portion of the magnetic ring diameter freely projects outward in the radial direction. The magnetic ring  90  is part of a generator unit of the processing degree indicator and will be described in greater detail in what follows. 
         [0023]    A cylindrical bearing bushing  19  projects downwardly from the underside of the rotor disk  18  and is provided with a lower flange  190  extending around the outside. By means of the bearing bushing  19  the secondary drive unit is seated on an axial cylinder  191  of the base  21 . A plurality of hold-down devices  192 , distributed around the outer circumference of the bearing bushing  19  and screwed together with the base  21 , extend behind the flange  190  and assure, without hampering its rotatability, that the secondary drive unit cannot be released from the axial cylinder  191  in the axial direction. As represented in  FIGS. 1 and 2 , a bearing sleeve  193  has been preferably pressed or glued on the axial cylinder  191 , which gives the structure greater stability and reduces wear. Greatly stressed areas of the driveshaft  8  and the central bearing opening of the base  21  of the top part  2  are provided with appropriate bearing sleeves in the same way. 
         [0024]      FIG. 3  now shows a longitudinal section through the top part  2  of the device  1  along the central shaft  4  and the generator axis. The magnetic ring  90 , which is clampingly maintained on a rotor ring  18  by means of the clamping ring  80 , passes through the stator  92 . On the side facing away from the magnetic ring  90 , the stator  92  is surrounded by a coil body  91 . A base plate  46  not only supports the stator  92  with the coil and magnetic ring  90 , but also an electronic unit, not visible in the sectional representation. The electronic unit  47  substantially includes a rectifier, a capacitor, a counter and illuminating means, particularly preferred in the form of light-emitting diodes  48 . At least one optical wave guide  49  provides the operative connection between the light-emitting diodes  48  and a display unit  40  arranged in the cover. Employment of the at least one optical wave guide permits the placement of the illuminating means directly on the base plate  46 , instead of in the display unit  40  in the cover  20 , which considerably lowers manufacturing costs. All electrical contacts for the illuminating means can be arranged on the base plate, and the optical wave guides make cable connections to the display unit in the cover unnecessary. The display unit  40  arranged at an upper end of the optical wave guide can be attached as a separate piece in a suitable perforation in the cover  20 , or can be embodied in one piece with the optical wave guide. The optical wave guide and the display unit have been preferably produced by means of an extrusion process from a suitable transparent light-conducting plastic material. 
         [0025]    The generator  45  supplies the electronic unit  47  with electrical current. As also mentioned, the electronic unit  47  is arranged, together with the generator  45 , preferably on the base plate  46 , which can be fastened on the bottom  29  of the base plate  21 , for example by means of nipples. This modular construction permits the production of simpler embodiments of the device without a processing degree indicator, wherein the base plate  46  with the generator  45  and the electronic unit  47  is simply omitted during production and, depending on the embodiment form of the cover  20 , the reception opening for the display unit  40  is closed off with a suitable insert. In connection with such a simple model, the magnetic ring  90  and the clamping ring  80  have also been correspondingly omitted. But the remaining components of both devices can be produced with the same extrusion molds, which has an extremely advantageous effect on production costs. 
         [0026]    The electronic unit  47  and the display unit  40  are components of the processing degree indicator which, in accordance with the present invention, makes it possible also for untrained users to obtain cut material of an ideal cutting degree. The display unit  40  is arranged in the cover  20 , as shown in  FIG. 4 , for example, and can be easily viewed by the user. The position at the side of the cutout for the handle  11  has shown itself to be advantageous, in particular for right-handed people, since in two-handed use it remains facing the user and is not covered by the hand of the user with which the device is held. The processing degree indicator, in particular its display unit  40 , is advantageously constructed in a very simple manner and can be intuitively understood by the user without further instruction. Accordingly, in the exemplary embodiment in  FIG. 4 , a display unit  40  for three light-emitting diodes  48  has been inserted, easily visible to the user, into the cover  20 . The three LED&#39;s, for example in the colors green, yellow and red, are arranged on the base plate  46 . In the exemplary embodiment represented, the light from the three LEDs is conducted via the optical wave guide to the display unit in such a way, that there three light spots  48 ′ can be generated in a row next to each other. In this case a light spot  48 ′ is assigned to each LED. It is obvious to one skilled in the art that the employment of optical wave guides in accordance with the instant invention permits an enormous constructive variety of the display unit. For example, these can be designed in the form of letters, numbers, symbols and/or pictograms, wherein each display unit is comprised of one or several of such display elements. By means of only one light-emitting diode it is also possible to illuminate several display units, or several display elements within a display unit. However, a display unit  40  for only one light-emitting diode  48  is also possible, in which the light-emitting diode  48  changes colors by being appropriately triggered. 
         [0027]    In what follows, a functional example of the processing degree indicator in accordance with the invention will be described by means of the exemplary embodiment of  FIG. 4 , in which the degree of fineness of foodstuffs to be cut, for example of onions or other vegetables, is indicated to the user. For registering the number of revolutions of the processing unit, i.e. the cutting unit  60 , and therefore of the blades  611 ,  621 ,  631 , during the operation of the device, the number of revolutions of the rotor disk  18  is preferably detected by the electronic device and is intermediately stored. In the exemplary embodiment represented, the length of the pull cord has been selected to be 600 mm so that, with a corresponding diameter of the winder and corresponding gearing, the cutting unit rotates ten times over the entire circumference per pull on the pull cord (up to its complete unwinding). As soon as the intermediately stored value lies above a preset value (of 70 full revolutions of the rotor disk, for example), the green LED of the display is illuminated or blinks. By this it is indicated to the user that, although the material to be cut has been evenly comminuted, it is still rather coarse. The green LED is illuminated or blinks, preferably fed by a capacitor, as long as the cumulative number of revolutions lies below the preselected value of 150. The cutting unit  60 , as well as the rotor disk, are further rotated by further pulls on the cord pull and, after exceeding the threshold value of 150 revolutions, the display changes from green to yellow, i.e. the yellow LED is triggered and the green one switched off. In this way a signal is provided to the user that now the material to be cut is finely cut and, after approximately 100 further revolutions, the display changes into the red range, i.e. the red LED is illuminated or blinks instead of the yellow one. In this way the user is provided with the information that the material to be cut is now present in a very finely comminuted way and further processing would only result in finely pureed cut material. In accordance with a preferred embodiment, the green LED is active from 70 revolutions (corresponding to 7 pulls of the pull cord), the yellow one between 71 and 150, and the red one starting at 250. Since the revolutions of the rotor disk are being measured, it makes no difference whether the cord is respectively unwound completely or only partially, in any case the actual number of revolutions of the cutting means is detected and displayed. 
         [0028]    It is alternatively also possible to select the sequence yellow, green and red of the LED colors, so that still rough material to be cut is signaled by yellow color to the user, finer material to be cut by the green LED and very fine cut material, or puree, by red light. In a further form of embodiment, a low-consumption LCD display is provided in place of the LEDs, in which the increasing fineness of the material to be cut, or further processing progress, is symbolized by increasing bars, for example. 
         [0029]    In place of the above described display categories, which can rather be combined under the term of graphic display categories (green, yellow, red signals, or bar graphics), it is possible to represent the actually detected number of revolutions of the processing means on a suitable alpha-numeric display. This can be by itself, or be in combination with the previously described graphic displays. 
         [0030]    In accordance with a preferred embodiment, the measurement of the number of revolutions takes place by the counting of the voltage changes in the counting device prior to the ac-voltage being changed into a dc-voltage in the rectifier. However, it is also conceivable to count the visual detection of a marker, for example on the rotor disk, a magnetic marker, or even the passage through an electrical contact. 
         [0031]    Since it is often not desired to provide the device for foodstuff processing with a battery, the electrical current required for operating the electronic processing degree indicator is preferably generated by the above mentioned generator  45 , which is operated by means of the rotating movement during cutting or processing. The voltage provided by the generator  45  is rectified and is used for charging a storage capacitor. The downstream connected electronic unit  47  and the light-emitting diodes  48  are provided with energy from this storage capacitor. The electrical current consumption by the electronic unit  47  and the LEDs is so low that the user practically does not notice the mechanical resistance generated by the generator  45 . To further reduce the electrical current consumption, it is possible to operate the LEDs in a blinking mode. In order to be able to omit additional operating elements and components connected therewith, in accordance with a preferred embodiment the electronic unit  47  switches off the display a few seconds after the stop of the drive mechanism  10  and returns the internal counter to zero. 
         [0032]    After the desired degree of fineness has been reached, the user stops and the cord  70  is rewound by means of the pre-wound restoring spring  72  until the handle  11  comes to rest in the recess  5  provided on the cover  20 . The top part  2  can be removed from the container  30  for the material to be cut, and the finished material can be removed or stored in the container. The user is always informed of the processing progress by the display unit arranged on the top of the device and need not open the device for checking. A table is made available to untrained users which indicates the degree of fineness which has been achieved in the respectively displayed category in connection with vegetables, fruits and/or herbs often used in the kitchen. 
         [0033]    The generator unit with the generator  45  and the magnetic ring  90  is represented in a view from above, and its mounting on the base plate  46  as well, in  FIGS. 5 and 6 . The one-piece magnetic ring  90 , which is fixed on the rotor disk  18  of the secondary drive unit, is divided into an even number of sectors  93  on its circumference. In this case the sectors  13  have been alternatingly magnetized on their surface in accordance with magnetic North N, or respectively magnetic South S. This magnetic ring  90  is now guided in a contactless manner by a stator  92  of the generator  45 . The alternating magnetic field generated in this way generates an ac-voltage, which is rectified in the electronic unit  47  and is sufficient for further electrical current supply of the electronic unit  47 , as well as of the light-emitting diodes  48 . 
         [0034]      FIGS. 7 and 8  show another embodiment of a device  1  with a one-piece drive mechanism  10 ′ with a further embodiment of the generator  45 ′. A generator wheel is connected by means of a positive or non-positive connection, which can for example be provided by means of gear wheels or rubber wheels, with a rotor disk  18 ′ of the drive mechanism. Here, the rotor disk  18 ′ is directly connected with the winder/cord roller  12 ′, so that electrical current is generated in the course of a processing step, as well as during reverse rotation caused by the spring. 
         [0035]    One skilled in the art will realize that the generator  45  in the above described exemplary embodiment with the two-piece drive mechanism  10  can also be driven by means of the primary, as well as by means of the secondary drive unit. 
         [0036]    The technical teaching in regard to the processing degree indicator can also be advantageously transferred to other manually operated kitchen utensils in which a desired degree of processing is correlated with a defined number of processing steps, preferably with revolutions of a drive or processing unit. 
         [0037]    Preferably, all further components of the device, with the exclusion of the blades  611 ,  621 ,  631 , the magnetic ring, the LEDs and the electronic unit, in particular all accessible surfaces and all surfaces which come into contact with foodstuffs, as well as the essential parts of the drive mechanism  10 , are made from plastics, such as SAN (styrene acrylonitrile), POM (polyoxy-methyline) and ABS (acrylonitrile butadiene styrene), by an extrusion process. In particular those parts which come into contact with the foodstuffs to be processed, are approved for use with foodstuffs. 
         [0038]    In preferred types of embodiment of the devices  1  in accordance with the instant invention, the diameter of the container  30  for the material to be cut lies between 120 and 140 mm at a height of 70 to 90 mm. The magnetic ring  90  is divided into 12 to 16 sectors  93 , and the coil body  91  of the stator  92  consists of 2,000 to 4,000, preferably 3,000 wire coils. An appropriate capacitive storage device is employed for the intermediate storage of the voltage. 
         [0039]    In place of blades, finger-shaped processing means are for example employed for peeling onions and/or garlic, such as are known from devices in accordance with the species. Processing means for cutting and for squeezing are combined with each other in one unit for processing of soft or pre-cooked vegetables and/or fruit, in particular for preparing food for small children and babies. 
         [0040]    The devices in accordance with the invention can be employed in many ways in the kitchen or household by means of further inserts which are arranged in the lower part  3  in place of the cutting unit  60  and can be put into rotation by means of the drive mechanism  10 , for example by means of a basket for centrifuging herbs, an S-shaped mixing arm, or a beater for frothing milk. 
         [0041]    The processing container  30  for material to be cut which, in embodiments described up to now, had been shown to be substantially rotationally round and with its diameter slightly tapering downward, can also be simply exchanged and adapted to the respective purpose of use. The container  30  for the material to be processed with the finished processed material can be closed off by a separate cover and stored. To this end the cutting unit  60  or other processing insert is removed. With a second container  30  for material to be cut, the device in accordance with the invention is again ready for use. 
         [0042]    In accordance with a further embodiment of the invention, not represented in the drawings, the drive unit is housed in a device base, and the processing container with the processing means and a cover on the top are placed on this device basis. Driving can again take place by means of a cord pull or other suitable manual drive mechanism. The display unit is arranged on the device in such a way that it is easily visible to the user during the operation of the device.
