Description

Title: Composters

Field of the invention

The invention relates to a composter with at least one closable filling opening at the top, with three superimposed chambers inside, an upper intermediate bottom between the upper and middle chamber, a lower intermediate bottom between the middle and lower chamber and at least one closable side Entnahmöffhung in the area of the lower chamber.

State of the art

Home composters are mostly cylindrical, cubic or pyramidal containers open at the bottom. The composting, organic waste, such as vegetable waste and fruit waste, are introduced into the container and rot inside the container under oxygen access and with the help of soil bacteria and microorganisms. The organic waste is converted into earthy components such as humus. Known composters are constructed of prefabricated elements made of plastic, wood or metal, and are provided with appropriate ventilation openings to facilitate composting.

In the case of the known composters used in the private household, there is the problem that the possible exchange of air through the perforated wall or with other air intakes is possible only with the waste immediately adjacent to the wall, while the rest of the content of the composter does not exceed that required for the Composting necessary access of oxygen has yet to release up to 70% moisture vapor, which is contained in fresh green waste.

The result is that the compost material without enough oxygen rotten smelling bad, which leads in addition to the known odor nuisance even to an inferior compost as the final product.

In order to remedy this situation, known composters are equipped with flaps, removable walls or the like, wherein the user of the composter is required to convert the compost material contained in the composter in the rhythm of 4 to 6 weeks.

This implementation involves a series of manual activities. First you have to open a flap on the composter or remove a wall element. Then the entire compost material is to be removed from the composter through the resulting opening and piled up next to the composter. This usually happens gradually with the help of a shovel. With the help of the shovel, the removed compost can be thrown through a sieve to sift out the already to raw compost become smaller components from the compost and to separate from the rest of Kompostgut that must be filled back into the composter so that it can continue to compost there. After the sieving process and before refilling the composter, the flap must first be closed or the wall element re-inserted at the composter become. Only then can the remaining compost material be filled back into the composter using the scoop.

These activities must be done in a rhythm of 4 to 6 weeks if you want to get a high quality compost. Experience has shown that these activities are unpopular because they not only require a manual effort, but can also expose the user to nuisances caused by odors or numerous microorganisms present in the compost material. If the compost material is not used for a long time, it can even cause a risk of disease, because it can form fungal fungi in organic material under different conditions, which can lead to illnesses in people with a reduced immune system. Too frequent conversion in turn disturbs especially the advanced composting and leads to a reduced quality of the resulting compost.

From EP 1 118 604 A2 a composter in the form of a rectangular box is known, which contains three superimposed, equally large chambers, which are separated by sliding out of the box sliding shelves. The box is closed at the top by a hinged lid. The arranged under the hinged lid, upper chamber is open at the top. Between her and the middle chamber, an upper sliding floor is arranged. Between the middle chamber and the lower chamber, a lower sliding floor is arranged. The waste is entered into the upper chamber. When pulling out the upper sliding floor, the waste falls into the underlying middle chamber. When pulling out the lower sliding floor, the waste falls into the underlying lower chamber. The box is provided in the lower chamber with a flap through which the compost is removed from the lower chamber of the box. In this composter, arranged in the side walls of the box guides for the sliding floors are glued by the waste. As a result, the sliding floors after some time no longer or only very difficult to move. In this composter, only a portion of the volume is used for composting, because the three chambers are the same size, while the volume of the compost material is constantly smaller according to the progress of composting, because moisture is separated from the compost and the Vererdungsprozess a further significant volume reduction entry. Of the waste introduced into the upper chamber, only about 60% of the original volume is contained in the middle chamber and only about 30% of the original volume in the lower chamber. As a result, a disproportionately large proportion of the volume of the composter is unused.

Summary of the invention

The object of the invention is to provide a composter which avoids the disadvantages mentioned above and allows a quick and intensive composting with little effort. The solution proposed is a new composter. The new composter has at least one closable filling opening at the top and three superimposed chambers in its interior, also an upper intermediate bottom between the upper chamber and the middle chamber, a lower intermediate bottom between the middle chamber and the lower chamber and finally at least one closable, lateral removal opening in the area of the lower chamber. The new composter is inventively characterized in that in the upper intermediate floor is provided at least one closable by a rotatable aperture transfer opening for the Kompostgut that is provided in the lower intermediate floor at least one closable by a rotatable aperture transfer opening for the compost, and that in the middle chamber at least one arranged above the lower shelf, is provided for discharging the Kompostgutes on the lower shelf movable scraper.

This training allows a simple transport of the composted material through the composter adapted to the accumulation of the waste and the progress of composting.

When the composter is empty, the transfer openings arranged in the two intermediate floors and each closable by a rotatable panel are closed. The gradually accumulating organic waste to be composted is introduced into the empty upper chamber via the filler opening of the composter. When the upper chamber is full, the upper chamber is emptied. For this purpose, the rotatable aperture is rotated and opened the transfer opening at each arranged in the upper intermediate floor transfer opening. The Kompostgut lying on the rotatable panel falls through the transfer opening into the middle chamber and remains on the lower shelf. Depending on the number and size of the transfer openings arranged in the upper intermediate floor, some compost material may remain on the upper intermediate floor. This Kompostgut can, if necessary, be moved by hand or with the help of an introduced via the open filling opening of the composter in the upper chamber auxiliary means in the respective transfer opening so that it passes through this into the middle chamber. After emptying the upper chamber, the upper intermediate bottom is first closed. For this purpose, the rotating aperture is rotated at each arranged in the upper intermediate floor transfer opening and closed the transfer opening. Subsequently, the gradually accumulating, organic waste to be composted via the filling opening of the composter are introduced into the empty upper chamber. The next time the upper chamber is full, first empty the middle chamber. For this purpose, the rotatable aperture is rotated and opened the transfer opening at each arranged in the lower intermediate floor transfer opening. The compost material lying on the rotatable panel drops through the transfer opening into the lower chamber and remains on the ground under the composter. Dependent on the number and size of the transfer arranged in the lower intermediate floor Openings leave some compost material on the lower shelf. This Kompostgut is moved using the movable over the lower shelf scraper in the respective transfer opening so that it passes through this into the lower chamber. After emptying the middle chamber, the lower intermediate bottom is first closed. For this purpose, the rotatable aperture is rotated at each arranged in the lower intermediate floor transfer opening and closed the transfer opening. Subsequently, the still full upper chamber, as described above, emptied. After emptying the upper chamber, the upper intermediate bottom is closed again. Subsequently, the organic waste, which is still gradually accumulating and to be composted, is reintroduced via the filler opening of the composter into the now empty upper chamber.

The finished compost is removed from the lower chamber via the side discharge opening of the composter. When all three chambers of the composter are filled, the finished compost must first be removed from the lower chamber and the lower chamber emptied. Thereafter, the contents of the middle chamber can be transferred to the now empty lower chamber. Subsequently, the contents of the upper chamber can be transferred to the now empty middle chamber. After closing the upper intermediate floor, the organic waste to be composted can be reintroduced into the now empty upper chamber.

The handles for actuating the rotatable apertures may be located on the outside of the composter.

According to a further feature of the invention, a rotatable about a vertical Drehach- se rotating element may be provided which extends from the top of the composter into the middle chamber, is provided at its upper end with a control element and in the middle chamber at least one aperture for closing a arranged in the lower intermediate floor transfer opening carries.

In this embodiment, the handle for actuating a lower intermediate floor associated, rotatable aperture on the top of the composter is arranged.

According to a further feature of the invention, the rotary member in the middle chamber carry at least two diametrically projecting apertures, which are each associated with at least one arranged in the lower intermediate floor transfer opening. This design makes it possible to actuate two rotatable diaphragms, which are associated with two transfer openings arranged in the lower intermediate floor, from the top side of the composter.

According to a further feature of the invention, a rotatable about a vertical axis of rotation rotary member may be provided which extends from the top of the composter to the middle chamber, at its upper end with a control element is provided and in the middle chamber carries at least one, for discharging the compost material on the lower shelf movable scraper.

This design makes it possible to operate the scraper movable over the lower intermediate bottom from the top side of the composter. According to a further feature of the invention, a rotatable about a vertical axis of rotation rotary member may be provided, which extends from the top of the composter to the middle chamber, is provided at its upper end with a control element and in the middle chamber at least one through the middle Chamber carries movable leveling element. This design provides a leveling element movable through the central chamber which is operable from the top of the composter to slightly distribute the compost in the middle chamber.

According to the invention, the rotary element extending from the top side of the composter into the central chamber can carry at least one wiper which is arranged in the upper chamber and can be moved there to discharge the compost over the upper intermediate bottom.

According to a further feature of the invention, a rotatable about a vertical axis of rotation rotary member may be provided, which extends from the top of the composter into the upper chamber, is provided at its upper end with a control element and in the upper chamber at least one aperture for closing a arranged in the upper intermediate floor transfer opening carries.

In this embodiment, the handle for actuating a the upper intermediate bottom associated, rotatable aperture at the top of the composter is arranged.

According to the invention, the rotary element in the upper chamber can carry at least two diametrically protruding diaphragms which are each associated with at least one transfer opening arranged in the upper intermediate floor.

This design makes it possible to leave the upper chamber unaerated and to close to the outside. With the usual household composting, only a small amount is dropped daily

Quantities of waste. These can produce no warming of the compost material after introduction into the composter because of the small amounts. If the upper one

Chamber is not ventilated, the daily introduced amount of waste can neither release moisture nor compost significant composting. Another advantage is that a settlement of the waste with insects is almost completely prevented.

According to a further feature of the invention, the composter may have a downwardly flared skirt, wherein the volume of the upper chamber is smaller than the volume of the middle chamber and the volume of the middle chamber is smaller than the volume of the lower chamber. According to a further feature of the invention, the volume of the middle chamber may be three times the volume of the upper chamber and the volume of the lower chamber may be twice the volume of the middle chamber.

Description of exemplary embodiments

The composter has three chambers 1, 2, 3. The outer shape of the composter is a downwardly widening cone. The volume of the upper chamber 1 is smaller than the volume of the middle chamber 2, the volume of which is smaller than the volume of the lower chamber 3.

Symmetrical to a diameter of the upper surface, which is arranged on the upper side of the upper chamber 1, there extends a web 16 arranged on the upper side of the composter, to which hinges 13, 14 for the filler openings of the composter are articulated via parallel hinges. The lower chamber 3 has a lateral removal opening, which is closed by a removal flap 12. The lower chamber 3 is open at the bottom, so that the compost material contained in it can come into contact with soil bacteria and contained in the ground 15 35 microorganisms that promote composting.

The jacket of the composter, which encloses the middle chamber 2 and the lower chamber 3, is provided with ventilation apertures 17. Likewise, the lower intermediate bottom 8 of the composter and the lower, rotatable diaphragm 9, which is arranged between the middle chamber 2 and the lower chamber 3.

The jacket of the composter, however, surrounding the upper chamber 1, is designed without ventilation openings. Likewise, the upper intermediate bottom 4 of the composter and the upper, rotatable diaphragm 7, which is arranged between the upper chamber 1 and the middle chamber 2. With closed lids 13, 14 and located in the closed position, upper panel 7 no ventilation of the upper chamber 1 takes place.

Concentric to the vertical longitudinal central axis of the composter, a vertical hollow shaft 6 is arranged. This is connected in the region of the upper intermediate bottom 4 with the upper, rotatable diaphragm 7, which is arranged just above the upper intermediate bottom 4 and for opening and closing the upper intermediate bottom 4 arranged transfer opening relative to the upper intermediate bottom 4 is rotatable.

In the vertical hollow shaft 6, a vertical rotary shaft 10 is arranged. The rotary shaft 10 is connected in the region of the lower intermediate floor 8 with the lower, rotatable aperture 9, is arranged just above the lower intermediate floor 8 and for opening and closing the arranged in the lower intermediate floor 8 transfer opening relative to the lower intermediate floor 8 is rotatable.

Rotary shaft 10 and hollow shaft 6 pass through the web 16 arranged on the upper side of the composter and are provided with levers 5 and 11 at their upper end regions. About the lever 5, the hollow shaft 6 so that the upper rotatable aperture 7 is rotated become. About the lever 11, the rotary shaft 10 and thus the lower, rotatable aperture 9 can be rotated.

In Fig. 1, the rotatable apertures 7, 9 are shown in the transfer position, in which they release the transfer openings in the upper intermediate bottom 4 and lower intermediate bottom 8. In this position, the rotatable aperture 7, 9, the levers 5 and 11 are arranged transversely to the web 16.

In Fig. 2, the levers 5 and 11 are aligned parallel to the web 16. This orientation of the levers 5 and 11 indicates that the rotatable diaphragms 7, 9 located in the interior of the composter are in their closed position and close the transfer openings in the upper intermediate bottom 4 or lower intermediate bottom 8.

On the position of the two levers 5 and 11 at the top of the composter, the position of the rotatable apertures 7, 9 in the interior of the composter can be easily monitored. In addition, the transverse position of the levers 5 and 11 prevents opening of the compartments closing the entry openings of the composter 13, 14. This prevents the throwing of fresh waste into the upper chamber 1, when the transfer openings in the upper intermediate bottom 4 and lower intermediate bottom. 8 are open.

Fig. 3 shows the upper chamber 1 and the middle chamber 2 as two separate components, which are placed on each other. Between the upper chamber 1 and the middle chamber 2, the upper intermediate bottom 4 of the composter is arranged. In this intermediate floor 4 transfer openings 21 are provided, which are covered by sections of the upper, rotatable aperture 7. The upper, rotatable diaphragm 7 is connected to the hollow shaft 6. This is provided with an extension downwards, which extends into the lower chamber 2. In the lower chamber 2, a finger-shaped leveling element 24 is fixed to the hollow shaft 6, which can be moved by rotating the hollow shaft 6 through the lower chamber 2. With the leveling element 24, the compost material accumulating under the transfer openings 21 can be distributed via the lower chamber 2. The rotary shaft 10 extends through the hollow shaft 6 down through and extends to the lower, rotatable aperture 9. When turning the hollow shaft 6, the upper, rotatable aperture 7 rotates in the left half of the drawing out of the plane of the paper and in the right drawing plane in the Paper plane into it. In the right half of the drawing can be seen in the direction of rotation of the upper, rotatable aperture 7 behind the transfer opening 21 scraper 18, which passes through the hollow shaft 6. Between the upper intermediate bottom 4 and the scraper 18, a gap of, for example, 2 cm is provided, through which the upper, rotatable diaphragm 7 can rotate. The scraper 18 has, for example, a height of 5 cm. When rotating the upper, rotatable aperture 7 of the scraper 18 pushes the lying on the panel 7 Kompostgut into the transfer opening 21. To cause no damage to the composter by large hard components in the compost, the scraper 18 is resiliently mounted in the composter, so he such Components can dodge against the force of the spring. In which the middle chamber 2 surrounding jacket 20 of the composter ventilation apertures 17 are provided. Of the the upper chamber 1 surrounding jacket 19 of the composter, however, is completely closed.

FIG. 4 shows the upper intermediate bottom 4, designed as a circular disk, which has two diametrically opposite, approximately four-round transfer openings 21. In the middle of the upper intermediate floor 4, a passage opening 24 for the passage of the rotary shaft 10 is provided.

Fig. 5 shows the upper, rotatable diaphragm 7, which has two diametrically opposed, kreissektorfÖrmige sections 23 which cover the two about vierilkreisförmige transfer openings 21 in the upper intermediate bottom 4 in the closed position of the upper, rotatable aperture 7. In the middle of the rotatable aperture 7, the hollow shaft 6 is fixed. The upper intermediate bottom 4 and the upper, rotatable diaphragm 7 are not perforated, i. they have no ventilation breakthroughs. The same applies to the upper chamber 1 surrounding jacket 19 of the composter and also for the lid 13, 14, which close the filling openings of the composter. The upper chamber 1 is therefore limited by components, all of which have no ventilation openings. The upper chamber 1 of the composter is therefore not ventilated.

Fig. 6 shows the lower intermediate bottom 8, which is arranged between the middle chamber 2 and the lower chamber 3. The lower intermediate bottom 8 has two diametrically opposite, kreissektorfÖrmige transfer openings 21. The lower he intermediate bottom 8 is made of perforated material, i. he has ventilation openings 17.

Fig. 7 shows the lower, rotatable aperture 9, which is arranged between the middle chamber 2 and the lower chamber 3. The lower, rotatable diaphragm 9 has two diametrically opposite, kreissektorfÖrmige sections 23 which cover the two circular sector-shaped transfer openings 21 in the lower intermediate bottom 8 in the closed position of the lower, rotatable aperture 9. The lower rotatable shutter 9 is also made of perforated material, i. it has ventilation openings 17. The same applies to the jacket 20 surrounding the middle chamber 2 and the lower chamber 3 of the composter. The middle chamber 2 and the lower chamber 3 are limited by components which have all the ventilation openings. The middle chamber 2 and the lower chamber 3 are therefore constantly ventilated and the composting in the two chambers is promoted by the ventilation.

When using the composter fresh waste is thrown into the upper chamber 1 after opening one of the covers 13, 14. Since the lids can only be opened when the levers 5, 11 are parallel to the web 16, it is ensured that the fresh waste can not get out of the upper chamber 1 into the middle chamber 2. Since the upper chamber 1 is not ventilated, the daily introduced amounts of waste can neither release moisture nor compost appreciably, whereby the insect infestation is kept low. Only when the upper chamber 1 is approximately filled, for example after 2 to 3 weeks, is rotated by rotation of the hollow shaft 6 via the lever 5, the upper, rotatable Aperture 7 is rotated into the transfer position, so that the contents of the upper chamber 1 can fall through the transfer opening 21 in the upper intermediate bottom 4 in the middle chamber 2. By the rotation of the upper, rotatable aperture 7, the compost is mixed and aerated. An attached to the hollow shaft 6 equalization element 24 rotates with the hollow shaft 6 and distributes the accumulated below the transfer opening 21 Kompostgut evenly over the middle chamber 2. The scraper 18 pushes the lying on the circular sector-shaped sections 23 of the upper, rotatable aperture 7 Kompostgut the transfer opening 21. Finally, the upper, rotatable diaphragm 7 is again rotated in the closed position and it can be collected again in the upper chamber 1 fresh waste, while in the middle chamber 2 the previously fallen through compost can calmly compost without that danger that fresh waste falls into the middle chamber 2.

Through the ventilation openings 17, which are present in the jacket 20 surrounding the middle chamber 2, in the lower intermediate floor 8 and in the lower rotatable aperture 9, oxygen now passes to the composted material in the middle chamber 2. In the compost material is an active Composting, wherein the relatively large amount of Kompostgut heats up vigorously in the first few days and thus a large part of the moisture is excreted through the ventilation openings 17 from the composter, while at the same time a high degree of warming of the compost is achieved with the destruction of weed seeds , The release of moisture leads to a substantial volume reduction, so that until the next emptying of the upper chamber 1, the volume in the middle chamber 2 is reduced to about 60%. It has proven to be advantageous if the volume of the middle chamber 2 is about three times the volume of the upper chamber 1. Only when the middle chamber 2 is full, e.g. after 2 to 3 months, the lower rotatable shutter 9 is rotated by turning the rotary shaft 10 via the lever 1 1 and the transfer openings 21 in the lower shelf 8 released so that the cooled in the meantime, progressively composted waste falls into the lower chamber 3 , The rotation again causes mixing and additional ventilation of the compost material. A scraper 18 on the lower, rotatable aperture 9 in turn pushes the compost material lying on the panel 9 in the transfer opening 21. At a projecting into the lower chamber 3 end of the rotary shaft 10 may also be a leveling element for uniform distribution of the lower chamber 3 below be attached to the transfer opening 21 accumulated compost material. Thereafter, the lower, rotatable aperture 9 is brought back into the closed position so that compost, which is transferred from the upper chamber 1 in the middle chamber 2, can not fall into the lower chamber 3.

The jacket 20 surrounding the lower chamber 3 of the composter also has ventilation openings 17 and the lower chamber 3 has no bottom. The Kompostgut in the lower chamber 3 is well ventilated and comes with the garden floor 15 and - II - the soil bacteria and microorganisms in it, which complete composting. This clearly shows the advantage that the compost material in the middle chamber 2 has already largely released its thermal energy due to the sudden supply of air, so that the heat-sensitive bacteria and animals responsible for the further composting can better utilize the already cooled compost material ,

From the lower chamber 3, after several months through the lateral removal flap 12 raw compost without mixed fresh waste, as occurs in conventional composters are removed. By resting in the middle chamber 2 and in the lower chamber 3 for longer periods undisturbed resting and maturing of the compost, a high-quality composting takes place, which is superior to previous composters.

Fig. 8 shows a top section 25 consisting of a middle section 26 and a lower section 27 composter in the erected state. Fig. 9 shows the composter of Fig. 8 in transport ready condition, wherein the three sections 25, 26, 27 are turned upside down and nested.
