Description

Apparatus for comminuting solid and substantially dry household waste

The invention relates to a device for comminuting solid and substantially dry household waste, in particular plastic packaging, such as polyethylene terephthalate (PET) and / or sheet metal, such as aluminum sheet. The device comprises a housing suitable for installation in a kitchen appliance, in particular in a kitchenette or a kitchen cabinet, and / or for installation in a kitchen, and a comminuting unit accommodated in the housing with at least one feed opening for the household waste to be comminuted and a plurality of rotatable comminution means , Furthermore, the comminution device comprises a collecting unit accommodated in the housing below the comminution unit, with at least one receptacle for the comminuted household waste. In a modern household, a large amount of household waste accumulates at regular intervals, in particular due to the many packages made of plastic or sheet metal. Above all, the containers contained in household waste, such as PET bottles or aluminum cans, are often very bulky and require a relatively large amount of space for their weight, since they are often not compressed or compressed before they are fed to a waste collection system. This brings a frequent disposal of household waste in the local collection station with it or makes large waste containers with a corresponding capacity required. As a result, the large volume of household waste often leads to a regular overfilling of collection stations and drives up the costs of waste disposal for both the private household and the disposal companies.

Another important aspect is the recycling of at least part of the household waste generated. In this context, it is particularly important to separate household waste as reliably as possible into its various basic materials, such as different types of plastic, metal, white and stained glass, paper and biowaste, and to feed the recovered raw materials to the respective recycling process. In order to achieve a reduction of the volume or a compression of at least a portion of household waste and a complete sorting as possible in the basic materials, it is proposed in the prior art, inter alia, at least a portion of household waste, especially the plastic and sheet metal waste already in the Fully automatically shred households and divide or separate into the different, recyclable precursors or raw materials. The raw materials are then returned to industry for reuse.

Various devices for comminution and fractionation of household waste are known from the prior art. These shredding s devices are intended for immediate use in the household itself, ie directly where the household waste is generated. For example, DE 102 36 710 A1 shows a comminution device for domestic waste comprising a comminuting unit and a collecting unit arranged thereunder. The described shredding s device is pulled out along a side-mounted rails from a kitchen cabinet and to be shredded household waste is entered through an opening at the top of the crushing device in this. The shredding unit comprises at least two roller-type separating means, which comminute the input household waste and forward it to the collecting unit arranged thereunder, where the shredded household waste is deposited. The release agent of the crushing unit can be removed by simple means from the crushing device and thus can be cleaned in a simple manner.

From DE 41 14 751 C2 an apparatus for cutting and breaking empty containers into small pieces of material is known. The material to be shredded is fed from above into the device and cut or broken by standing cutting rollers. The thus shredded materials continue to move down the device and fall through an opening into one of several garbage containers which has been positioned with a mechanical actuator under the opening. Also, from DE 43 27 127 AI a recycling device, in particular for use in the household, known, which recycling device comprises a sensor unit for determining the supplied material. It is envisaged, in accordance with the output signal of the sensor unit, to cut or break the supplied material, optionally to compensate prime and deliver according to the material detected to the respective packaging unit where the shredded and separated material is packed for further use. For this recycling device, a cleaning and / or sterilization device is further described which ensures a hygienically perfect condition of the recycling device.

All of these comminution devices have the disadvantage that either the comminution unit and often also other parts of the comminution device have to be pulled out of a housing or cabinet each time before use and / or that the feed opening for the material to be comminuted is located at the top side of the comminution device is arranged so that, for example, when setting up the crushing device in a kitchen, the top of the crushing device can not otherwise be used, for example, as a storage area. It is therefore an object of the invention to overcome these disadvantages when using a conventional crushing device.

This object is achieved with a device of the type mentioned above in that the at least one feed opening of the shredding unit is accessible via a front side of the housing and the household waste to be shredded can be introduced substantially horizontally from the front, and that at least part of the collecting unit and / or a part of the housing is moved forward out of the housing, so that the at least one receptacle is accessible from the front of the housing. In this way, a device for crushing solid and substantially dry household waste is created, which allows a particularly comfortable use and also very well suited for installation in a kitchen device and / or for installation in a kitchen, since the at least one Supply opening of the crushing unit and the at least one collecting container of the collecting unit from the front of the housing of the crushing s device can be accessed. Is the

Shredding s device housed in a kitchen cabinet or the like, so the housing or the shredder unit of shredding s device must not first pulled out of the kitchen cabinet during use each time and moved off and off closing be moved back. This particularly increases the user-friendliness of the comminution device. Likewise, in the case of an embodiment of the comminution device, the upper side of the comminution device or of the housing for a different use, for example as a storage or work surface, remains free as a free-standing set-up device. This ensures in particular a more efficient use of space or space in a kitchen. Extraction of at least a portion of the collecting unit is necessary at most when emptying the at least one collecting container.

Advantageous embodiments and further developments of the invention will become apparent from the dependent claims and from the description in conjunction with the figures.

It is favorable if an upper, if necessary wegbewegbare cover device, in particular a cover, at the front of the housing closes the at least one feed opening and a lower, if necessary wegbewegbare covering device on the front side of the housing conceals the collecting unit in a closed state in the housing. On the one hand, this ensures the easy and at any time accessibility of the at least one feed opening of the comminution device and the at least one receptacle in the catching unit from the front of the housing of the comminution device, and on the other hand, in particular in connection with a securing device, the safety of use of the comminuting device and In particular, the safety of children is given sufficiently.

It is also favorable if insulation and / or sealing elements are arranged in a wall of the housing and / or in the upper and lower cover device and / or in a closed state between the housing and the cover devices. In this way, the odor and / or noise pollution outside the shredding device is minimized.

It is particularly advantageous if the rotatable comminution means, in particular comminution rollers, mesh in pairs in the comminuting unit and the household waste to be comminuted is transported substantially vertically through the comminution means and thereby processed, and if between the at least one feed opening and the comminution means of the comminution unit preferably a feed direction is arranged. In this way, the household refuse, which is supplied substantially horizontally into the at least one feed opening, is comminuted in the comminution unit by the comminution means substantially along a vertical processing direction. This combines the advantages of a substantially horizontal input of the household waste from the front into the comminution device with the advantage of a substantially vertical processing direction of household waste in the comminution unit, whereby a simple further transport of the comminuted household waste by gravity into the at least one collecting container of the collecting unit is ensured. For transporting the domestic waste to be comminuted from the at least one feed opening of the comminution device to the comminution means of the comminution unit, a feed device is preferably provided.

It is also advantageous if three or more comminuting rollers are formed in series next to each other in the comminution unit and each of the juxtaposed comminution rollers mesh with one another, wherein one direction of rotation of the comminution is reversible. In a first, advantageous embodiment, the end faces of the comminution rollers are arranged along a line. In an alternative, advantageous embodiment, in at least one group of three juxtaposed comminution rollers, the middle comminution swalze is offset downwards relative to the line, and the end faces of the two other comminuting rollers are arranged along the line.

In this way, it is possible with the crushing s rolling the shredding unit to realize different processing options and sorting by the shredding household waste to the corresponding roller pair and thus a certain processing sbereich preferably supplied to the feeder and, if necessary, the direction of rotation of the series-connected Milling rollers is reversed so that the household waste to be shredded is processed vertically downwards. Down-centered comminution rollers reduce the linear expansion of the comminution rollers in series, thus minimizing the size of the comminution unit.

It is also favorable if at least one of the downwardly offset comminution rollers has an enlarged diameter relative to the two adjacent, non-downsized comminution rollers. In this way, comminution is possible. created unit, which has a greater distance between the two adjoining, not offset down comminution rollers, so that even larger waste parts between the two spaced, adjacent crushing s rollers can be transported through to the underlying processing areas of the roller pairs.

It is also particularly advantageous if at least one of the axes of rotation of a pair of comminuting rollers is held in a rest position by a spring device of a certain strength. In this way, at least one of the comminution rollers of a pair of rollers may over- load when overloaded, for example during the supply of a solid, metallic object, and an overload, blockage and / or damage to the comminution device is actively prevented.

It is also advantageous if the roll disks of the comminution rollers have a spacing in the axial direction of between 1 mm and 30 mm. In this way, sufficient comminution and thus volume reduction of household waste is ensured, since the average grain size of the shredded household waste is in the range of the selected distance of the roll disks.

Finally, it is advantageous if the collecting unit comprises a plurality of collecting containers and preferably a sorting unit is arranged between the comminuting unit and the collecting unit of the comminuting device, which sorting unit automatically directs the different types of shredded household waste into the respective collecting container. In this way, a comprehensive separation and thus more efficient recyclability of the shredded household waste is ensured. Due to the design of the sorting unit, it is also possible, for example, for only one pair of comminution rollers and thus only one processing area, to distribute the comminuted household refuse to a plurality of receptacles, so that a separation into different base materials is carried out. Finally, the convenience and ease of use of the shredder are increased by the fully automatic detection and sorting of household waste.

1 shows a device 1 for comminuting solid and substantially dry domestic waste 2 in a housing 3.

According to a first embodiment, the housing 3 of the comminution device 1 is designed such that it is suitable for installation in a kitchen appliance or kitchenette and thus in particular in one of the lower cabinets of the kitchen appliance. The outer dimensions of the housing 3 are thus based on the current standards or standard values for fitted kitchens. The housing 3 therefore has, viewed from a front side 4, preferably a width of 45 cm or 60 cm, a maximum depth of 60 cm and a height of approximately 85 cm. According to a further embodiment, the housing 3 is designed such that the comminution device 1 is suitable for free installation in a kitchen. The outer dimensions of the housing 3 are substantially equal to the outer dimensions of the built-in device described above. An outer side 5 of the housing 3 is, however, adapted in function and appearance of the free installation of the shredding s device 1.

In the housing 3 of the comminution s device 1 is located in a first, preferably upper level 6, a control and operation unit. This unit comprises the necessary electronic components for the control and operation of the crushing device 1. At the front 4 of the control and operating unit controls 7 and display elements 8 are formed.

In Fig. 2a is a side view of the crushing device 1 is shown with an open side wall. In this illustration, it can be seen that in a second, preferably middle plane 9 of the comminution device 1, a comminution unit 10 is provided, comprising a feed device 11 and a plurality of rotatably mounted comminution means 12, in particular comminution rollers 13. The feeding device 11 has at least one feed opening 14 on the front side 4 of the comminution device 1, via which feed opening 14 the household refuse 2 to be comminuted is fed into the feed device 11 and transported further by the latter to the comminuting means 12, where the household refuse 2 is comminuted ,

The comminution means 12 or comminution rollers 13 are preferably driven electrically via at least one electric motor, which draws its energy from the household power network, and engage in pairs. In each area in which two juxtaposed shredding means 12 and crushing rollers 13 intermesh, a processing area 15 of the shredding unit 10 is formed. In each processing Scope 15 can be supplied to household refuse 2 and it is there the crushing by the crushing 12 or crushing s rollers 13th

The comminuted household refuse 2 then passes into a lower level 16 in the housing 3 of the comminution device 1, in which lower level 16 a collecting unit 17 is accommodated. The collecting unit 17 comprises at least one collecting container 18 for the comminuted household waste 2.

The at least one feed opening 14 of the comminution unit 10 is accessible via the front side 4 of the housing 3 and the household waste 2 to be comminuted can be introduced substantially horizontally from the front into the comminution device 1 or the feed opening 14 of the comminution unit 10. The feed opening 14 is preferably closed by an upper, if necessary wegbewegbare cover 19, in particular a cover, on the front side 4 of the housing 3. The upper covering device 19 can be folded downwards, in particular via hinges 20 and by means of a handle 24, so that the household refuse 2 to be comminuted can be entered into the feed opening 14 of the comminution unit 10 in a simple manner.

At least a part 44 of the collecting unit 17 can be pulled out of the housing 3 forwardly by means of a rail and roller device 21, the at least one collecting container 18 being moved forwards or out of the housing 3 when the part 44 of the collecting unit 17 moves outwards, so that the at least one collecting container 18 is accessible from the front side 4 of the housing 3. On the front side of the extendable part 44 of the collecting unit 17, a lower covering device 22 with an extension handle 23 is attached. When closed, the lower cover device 22 conceals or closes the collecting unit 17 in the housing 3 of the comminution device 1.

The comminution device 1 or its housing 3 is supported by means of in particular height-adjustable support elements 25 with respect to a lower support level 26, in particular a floor, at a distance.

According to a particularly advantageous embodiment are in the walls 27 of the housing 3 and in the upper cover 19 and the lower cover device 22 not shown insulation elements, in particular for noise reduction housed. In particular in order to avoid odor nuisance outside the comminution device 1, it is expedient to attach a sealing element 28 to the housing 3 of the comminution device 1 in such a way that the sealing element 28 is in the closed state of the comminution device 1 between the housing 3 and the upper covering device 19 or the lower cover 22 is arranged.

As can be seen in FIGS. 2 a and 3, in one possible embodiment, the comminution unit 10 comprises three comminuting rollers 13 whose axes of rotation 29 are arranged parallel to one another and in a horizontal plane next to one another, so that the adjacent comminuting rollers 13 mesh with their outer peripheral areas 30 in pairs. As already mentioned, each area in which the comminution rollers 13 intermesh each forms a processing area 15. Conveniently, the household refuse 2 to be shredded is transported substantially vertically through the comminution rollers 13 or through the processing areas 15 and is processed or comminuted.

In order for the processing direction to run from top to bottom in the currently used processing region 15, one direction of rotation 31 of the comminuting rollers 13 can be reversed as required. The respective directly next to each other and intermeshing crushing rollers 13 have opposite directions of rotation 31 in each case.

In order to transport the household waste 2 to be comminuted into the desired processing area 15 between the comminuting rollers 13, in the embodiment according to FIG. 2 a at least one part 45 of the feeding device 11 is designed to be movable. The formation of a plurality of processing areas 15 serves, in particular, to carry out a sorting or fractionation of the comminuted household waste 2. Depending on the type of household waste 2 to be comminuted, the corresponding processing area 15 is selected by means of the movable feed device 11 and the household refuse 2 is transported there. In each case a collecting container 18 is arranged below the respective processing region 15, in which the respective type of shredded domestic waste 2 is collected. Due to the vertical working direction of the processing areas 15 of the comminuting rollers 13, the fractions of the comminuted household refuse 2 fall by gravity into the speaking, arranged below the respective processing area 15 collecting container 18th

In principle, the feed device 11 comprises feed means, not shown, such as, for example, conveyor belts and driven rollers for further transport of the domestic waste 2 to be comminuted to the respective processing area 15 of the comminution rollers 13.

If, with a certain number of processing areas 15, a further number of fractions can be formed and sorted into the corresponding receptacles 18, which is particularly advantageous for cost and / or space reasons, in the lower level 16 of the comminuting device 1, between the Crushing unit 10 and the collecting unit 17 a sorting unit 32 is arranged. This sorting unit 32 is movable and distributed depending on the position, the different types of shredded household waste 2 on the currently selected collection container 18th

According to a particularly expedient embodiment, a movable feeding device 11 or a sorting unit 32 or a combination of movable feeding device 11 and sorting unit 32 automatically distributes the shredded household waste 2 to the respective collecting container 18 depending on its type. The respective type of household refuse 2 is, for example, by means of a sensor, not shown, in the feeder 11 and the movable part 45 of the feeder 11 and / or the sorting unit 32 are controlled accordingly. Such a sensor can be used, for example, for the optical recognition of the respective plastic (transparent, colored, etc.) or for reading out corresponding barcodes or radio transponders on the packaging.

The orientation of the axes of rotation 29 of the comminuting rollers 13 shown in FIG. 2a represents a first expedient embodiment. It is likewise possible to rotate the direction of the axes of rotation 29 by 90 ° in the horizontal plane according to another expedient embodiment, as shown in FIG. 2b is shown. In Fig. 2b, a crushing device 1 is shown in front view with removed covering devices 19, 22, wherein in turn the same reference numerals or component designations are used as in the previous Fig. 2a for the same parts. To avoid unnecessary repetitions Reference is made to the detailed description of the preceding Fig. 2a or reference.

Explicitly, however, mention should be made of the embodiment of the comminuting device 1 according to FIG. 2b that the mode of operation or direction of movement of a preferably present, in particular movable, feeding device 11 or a preferably present sorting unit 32 is to be correspondingly adjusted or also rotated by 90 °. Furthermore, by adding further crushing rollers 13 in the case of an arrangement of the rotary shafts 29, as in FIG. 2a, the depth of the housing 3 of the comminution device 1 increases during the arrangement of the rotary axes 29, as in FIG. 2b, the width of the housing 3 increases ,

In the case shown concretely, the comminution device 1 from FIG. 2 b is designed without a feed device 11 and with a sorting unit 32. The household refuse 2 to be shredded is manually input by a user of the shredding device 1 after folding away the upper covering device 19 via the respective feed opening 14, 14 'into one of the chambers 46, 47 above the corresponding processing areas 15 of the comminuting rollers 13. The two chambers 46, 47 are separated from each other by a wall element 48. After closing the upper cover 19 and / or after a corresponding operation by the user, the crushing operation starts and the sorting unit 32 transports the shredded household waste 2 into the selected receptacle 18. For setting the operation, preferably above each of the chambers 46, 47 in FIG upper level 6, which upper level 6, the control and operating unit of the crushing device 1, each a corresponding operating element 7, in particular a respective switch or button arranged.

In the illustrated embodiment, the left chamber 46 and the three corresponding left side crushing rollers 13 for the plastic waste (for example, a processing area 15 for the transparent plastic and a processing area 15 for the remaining plastic) and the right chamber 47 and the two corresponding, right-hand side Crushing rollers 13 provided for the waste metal or aluminum sheet. Depending on the requirement and number or arrangement of the processing areas 15 can also only one chamber 46, 47 or more than two chambers 46, 47 may be formed, wherein in each case a corresponding wall element 48 is arranged between the chambers 46, 47.

According to an alternative, not shown embodiment, the two right-side crushing rollers 13 of Fig. 2b, which crushing rollers 13 are provided for processing the sheet waste from the right chamber 47 of the crushing device 1, also be slightly spaced in their processing area 15, so that a sheet metal pressing device is realized , The spacing is in particular in a range of 1 mm to 10 mm. The outer right crushing roller 13 may in such a case also as a closed cylinder without individual roll disks 38, i. be executed with a continuous, closed shell section. Likewise, it is possible with fundamentally interlocking or meshing, right-side crushing rollers 13, the axis of rotation 29 of the extreme right crushing roller 13 to form movable side so that the two right-side crushing rollers can be spaced if necessary and the waste of metal or aluminum sheet optionally cut (with intermeshing comminution rollers 13) or pressed (with spaced comminution rollers 13).

FIG. 4 a shows a comminution unit 10 with four juxtaposed comminution rolls 13. The end faces 33 of the crushing rollers 13 are arranged along a line 34.

In the exemplary embodiment illustrated in FIG. 4a, all the comminuting rollers 13 intermesh, so that three processing areas 15 are formed. Likewise, it is possible not to form a middle processing area 35 and to arrange the two corresponding middle crushing rollers 36 at a distance, so that these comminution rollers 36 do not mesh with one another. This serves, in particular, to form a comminution unit 10 having a plurality of processing areas 15 with different roller pitches for producing comminuted household waste 2 having a different particle size.

As can be seen in Fig. 3, the roller pitch is given by a distance 37 of roller disks 38 of a crushing roller 13 in the axial direction. The roller pitch or the distance 37 defines the grain size of the shredded household waste 2 directly. Corresponding In a particularly advantageous embodiment, the distance 37 of the roller discs is set at a value between 1 mm and 30 mm.

FIG. 4 b shows a further embodiment of a comminution unit 10 with six comminuting rollers 13. Here, in each case a group of three juxtaposed crushing rollers 13, the middle crushing roller 39 relative to the line 34 offset down and the end faces 33 and axes of rotation 29 of the remaining crushing rollers 13 are arranged along the line 34. In this way, in particular the dimensions of the comminution unit 10 are reduced, since the comminution rollers 13 move closer together in one direction.

The comminution unit 10 according to FIG. 4b comprises five processing areas 15. As already described for the comminution rolls 13 of FIG. 4a, it is also possible here to not form, for example, the central processing area 35 between the middle comminuting rollers 36 and the two middle ones Comminution s rollers 36 spaced to arrange, so that two groups of processing areas 15 are formed with different roll pitch for the production of crushed household waste 2 with different grain sizes. As shown in Fig. 4b, it may also be useful if at least one of the downwardly offset crushing rollers 39 has a comparison with the two adjacent arranged, not offset down crushing rollers 13 enlarged diameter 41. In Fig. 3 by way of example for three crushing s rollers 13 is shown that expediently at least one of the axes of rotation 29 of a pair of intermeshing crushing rollers 13 with a spring device 42 of certain strength in the Ruhebzw shown. Working position is maintained. In the rest or working position of the rotary axes 29, the comminution rollers 13 engage in pairs in each other and when a supply of household waste 2 in the designated processing areas 15 of this is comminuted. The spring force of the spring device 42 is chosen to be correspondingly large, so that when a supply of comminuted household waste 2, the crushing rollers 13 remain in the rest or working position. Will now be a non-crushable object, such as a massive Metal part, introduced into the crushing unit 13, it is in the respective processing area 15 between the two corresponding crushing rollers 13 is pulled and the crushing roller 13 with a movable axis of rotation 29 moves to the side in a non-illustrated evasive position. Due to the forming distance between the two crushing rollers 13, the non-crushable object, the crushing unit 10 and in particular the crushing rollers 13 pass without damaging the crushing device 1 or destroy. After the non-comminutable object has been transported between the two comminution rollers 13, the spring device 42 automatically moves the comminution roller 13 moved to the side back to the rest or working position and the comminuting device 1 is ready for use again.

To ensure easy cleaning and thus a hygienic operation of the crushing device 1, it is expedient to perform bearings 43 of the axes of rotation 29 of the crushing rollers 13 so that a simple disassembly of the crushing rollers 13 is preferably possible without tools. Furthermore, it is expedient in this context to perform the crushing rollers 13 dishwasher safe.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the comminution device, these or their components have been shown partly unevenly and / or enlarged and / or reduced in size.
