Description

The invention relates to a filling socket, a filling socket system and a fireplace comprising a filling socket and a solid fuel fireplace system.

Solid fuel fireplaces are already known from the prior art, these are used to burn or utilize solids. In order to supply these systems with sufficient fuel, it is necessary to pump the fuel into the combustion chamber. This is usually done manually by opening a door and/or by a mechanical conveyor unit. However, the disadvantage of manual fuel supply is that it is expensive and has to be repeated frequently. When using a conveyor unit, however, a large amount of space is required to provide this conveyor unit and the associated storage space.

It is therefore the object of the present invention to be able to supply solid fuel into the combustion chamber of a solid fuel furnace, with only a small amount of space being required at the same time.

This object is achieved with a filling nozzle for a solid fireplace according to claim 1, with a filling nozzle system according to claim 8, with a fireplace according to claim 10 and with a fireplace system according to claim 15. Further features, embodiments, advantages and refinements of the invention result from the dependent claims, the description and the figures.

According to the invention is a filling nozzle for a solid fuel fireplace. The filling nozzle advantageously comprises a body, with the body having in particular a filling opening and/or a discharge opening, it being possible for a channel to be formed between the filling opening and the discharge opening, in particular through the body, with solid fuel, in particular pellets, being fed through the channel from the Filling opening can be routed to the discharge opening, or are arranged, with the filling opening extending in particular in a filling direction, with the discharge opening extending in a discharge direction, with the filling direction and the discharge direction advantageously being transverse, in particular perpendicular, to one another. The filling nozzle according to the invention serves to conduct fuel, in particular solid fuel, from a transport container, in particular a sack or box, into a combustion chamber or a storage space of a solid fuel burner or a solid fuel burner. For this purpose, the filling nozzle has a body, and this body can have a filling opening and a discharge opening. In addition to these two openings, the filling nozzle also includes a channel which extends between the filling opening and the discharge opening. For example, the body can have or form a channel through which solid fuel, in particular pellets, can be guided or transported from the filling opening to the discharge opening. Advantageously, the filler neck is designed in such a way that, especially in an installed position, the filler opening is formed above the discharge opening, so that the conduction or transport of solid fuel through the channel of the body of the filler neck can be or is driven by gravity. This results in a particularly energy-saving device. The filling opening extends in a filling direction, this filling direction advantageously being directed at least transversely to the vector of the gravitational acceleration, in particular in an installed state or in an installed position. The filling direction is in particular the average direction which a solid fuel has to take in order to be introduced into the filling opening. In the same way, the discharge direction of the discharge opening is, in particular, that direction which a solid fuel takes or must take when it is empty the discharge opening. Advantageously, the filling direction and the discharge direction can be oriented transversely to one another, in particular perpendicularly to one another. Transverse to one another is to be understood in particular as meaning that the smaller angle formed between the filling direction and the discharge direction is at least 45°, preferably at least 75° and particularly preferably at least 85°. By providing a filling nozzle, which has a discharge opening and a filling opening, which advantageously extend transversely to one another, a device can be provided by the invention which at the same time saves installation space and, moreover, in particular by utilizing gravity, is particularly compact and achieves or enables simple and fail-safe refilling or filling of solid fuel for a solid fuel fireplace. In an installed state, which can also be referred to as an installed position, the filling nozzle is advantageously oriented in such a way that the filling opening extends partially through an opening in a fireplace body of the solid-fuel fireplace and/or the discharge opening is conductively connected to a storage container and/or a combustion chamber or connected to a recovery room of the solid fuel fireplace.

The filling nozzle expediently has a chute that can be folded, in particular about a transverse axis, the chute having a main body, in particular flat, with the main body advantageously extending in a main direction, the chute being foldable, in particular out of the filling opening. The transverse axis is advantageously transverse, in particular perpendicular, to the filling direction and/or the outfeed direction. Particularly preferably, the transverse axis is also perpendicular to the direction of the vector of the acceleration due to gravity, at least in the installed position. This vector of the gravitational acceleration is advantageously arranged or oriented parallel to the direction of movement. A foldable means in particular that the chute, in particular its main body, has a rotary connection or a rotatable attachment to another component, in particular to the filling nozzle, so that at least a rotary movement of the entire chute or at least the main body is possible about the transverse axis in relation to the further component. Advantageously, this rotatable assembly of the main body or the chute of the filling nozzle is carried out in such a way that the translatory degrees of freedom are also completely restricted at the same time due to the possibility of rotation. In other words, this can mean that the chute or the main body of the chute can be fixed via a hinge on the filling nozzle or the body of the filling nozzle in such a way that rotation about the transverse axis is possible, but separation of the chute in relation to the body, in particular in a form-fitting manner, is prevented by the hinge or other fastening means. The main body of the chute is in particular that body or component or assembly of the chute which is foldably mounted on the body of the filling nozzle via a mounting means or fastening means. The main body is advantageously designed in one piece in order to achieve a chute that can withstand particularly high mechanical loads. This main body extends, inter alia, in a main direction, wherein the main direction of the main body can in particular be that direction in which the main body can have its largest main dimension. For example, the main direction of the main body can therefore be that direction in which the length of the main body is determined. Advantageously, this main direction can be oriented perpendicularly to the transverse axis.

The main body is preferably flat. A plane can be understood, among other things, to mean that the two dimensions in which the main body has its largest main dimensions are perpendicular to one another and/or span a plane. For example, the main body can therefore have its two largest dimensions in the main direction and in a direction perpendicular to this direction. Advantageously, the main body has its smallest dimensions in a direction, which in turn is perpendicular to these two directions, which should preferably not exceed 5 cm, 3 cm or 2 cm. The main body or the chute is expediently mounted on the body and/or on the filling nozzle in such a way that the main body is in a first (folded-in position) position of the chute or the entire chute is located within the filling opening and in a second position (opened or unfolded position) the chute is at least partially outside the filling opening. As a result, a particularly compact and space-saving configuration of a filling connection can be achieved. For example, this can be achieved in that the folding hinge, with which the chute is mounted on the body of the filling nozzle, is located inside the filling opening of the filling nozzle.

The chute expediently has two foldable side plates, which in particular can be folded around the main direction. By providing two, in particular foldable, side plates, a particularly user-friendly filling can be achieved because these side plates can, for example, prevent solid fuel from falling down to the side during a filling process. Due to the foldable arrangement of these side plates, the effect can be achieved that the chute is particularly space-saving and, in particular, can be placed within the filling opening in the folded position. The two side plates are in particular flat in order to achieve simple and cost-effective production. Additionally or alternatively, the side plates are preferably made of a plastic or a metal. However, the chute is particularly preferably made entirely of non-combustible material in order to minimize the risk of fire. The side plates are particularly preferably arranged in distal end regions of the main body, as seen in the direction of the transverse axis. The distal end areas are those areas of the main body in the direction of the transverse axis which are oriented parallel to the transverse axis and are located at most 3 cm, preferably at most 2 cm, from the distal end of the main body in the direction of the transverse axis. As a result, a particularly space-saving chute can be achieved.

In a preferred embodiment, the chute, in particular the main body, has a foreign body trap, in particular in the form of a perforated plate. By using a foreign body trap, the filler neck can achieve that the Combustion chamber of the fireplace to be filled and/or the storage container of the fireplace is not contaminated by foreign bodies such as nails or other non-combustible and/or unwanted foreign bodies. As a result, the filling nozzle can contribute to increasing the service life of the fireplace and/or to more environmentally friendly combustion. The foreign body trap can be designed in particular in the form of a perforated plate. This perforated plate is expediently flat, with a further collecting plate being able to be positioned in a direction perpendicular to the plane of the perforated plate in order to be able to reliably collect the separated foreign bodies. The perforated plate advantageously has a large number of holes, for example arranged regularly, which can expediently each have the same or different diameters.

In an alternative or additionally preferred embodiment, the chute has a support, the support being foldable, in particular about the transverse axis, relative to the main body. The support can expediently be folded around the transverse axis at an angle which is greater than 90 degrees. In other words, this can mean that the support, in particular in relation to the main body, can be rotated by more than 90 degrees. By providing a foldable support, a shelf for means of transport in which the solid fuel can be transported can be created in a particularly simple and effective manner. Therefore, for example, a storage option for sacks or boxes in which the solid fuel is transported can be created by the support. Thus, by providing the support, which can in particular be foldable about the transverse axis in relation to the main body, a particularly user-friendly and easy-to-handle filling option for a fireplace can be created.

The chute is expediently arranged such that it can be folded in such a way that it is arranged within the filling opening of the filling nozzle when the chute is in the folded-in position. This results in a particularly space-saving chute. One within the filling opening can be understood, among other things be sure the chute is fully within the fill opening in the folded position. For example, the filling opening protrudes beyond the folded-in chute in the filling direction in the folded-in setting/position.

Advantageously, the filling connector has a suction ring, with the suction ring in particular surrounding the conductive cross section of the duct and/or being guided around the conductive cross section of the duct in the manner of a ring. By providing a suction ring, the dust that occurs during a filling process can be sucked off in a simple manner, so that the health risk to an operator can be reduced and/or the ease of use of the filling nozzle can be increased. The suction ring is advantageously arranged in such a way that it annularly surrounds the cross section of the channel through which a solid fuel is guided, in particular from the filling opening to the discharge opening. In other words, the suction ring forms a complete ring around the cross section of the channel that is conductive for the solid fuel. In order to achieve an embodiment of the filling nozzle that is particularly easy to produce, the suction ring should be designed in such a way that it surrounds the channel in one plane, with this plane advantageously having a normal that can be oriented perpendicular to the filling direction and/or to the discharge direction.

In a preferred embodiment, the suction ring has a suction connection for directly or indirectly connecting a vacuum cleaner, and/or wherein the suction ring has suction openings for sucking dust out of the duct. The suction ring can be provided with a suction connection, which can be positioned in an installed state in such a way that a vacuum cleaner can be connected to it. For example, the suction connection can be designed in such a way that it extends from inside a fireplace body to a boundary wall of the fireplace body and penetrates the wall there, so that a vacuum cleaner can be easily connected to the suction connection from the outside. Advantageously, the suction port connected to the suction ring in such a way that the connection position of the suction connection on the suction ring is at the lowest point of the suction ring. In this way, gravity can be used in a particularly effective manner in order to improve suction. The suction ring advantageously has a large number of suction openings, which can be designed in such a way that dust can be sucked out of the channel into the suction ring, in particular if a vacuum cleaner is connected to the suction connection.

The ratio of the cross-sectional area of the discharge opening to a cross-sectional area of the filling opening is expediently in a range from 0.03 to 0.09, preferably in a range from 0.04 to 0.07, and particularly preferably in a range from 0.05 to 0 ,06. The relevant cross-sectional area is in particular that cross-sectional area at the distal ends of the discharge opening or the filling opening, the cross-sectional area being measured in particular perpendicularly to the filling direction or to the discharge direction. If the ratio of the cross-sectional area of the discharge opening to the cross-sectional area of the filling opening is in a range from 0.03 to 0.09, this allows a particularly simple and cost-effective production of the filling nozzle to be achieved. If this ratio is in a range from 0.04 to 0.07, the applicant has surprisingly found that a particularly simple and user-friendly filling through the filling nozzle can be realized as a result. However, if the relevant ratio is in a range from 0.05 to 0.06, a certain orientation of the fuel can be achieved during the filling process of the filler neck or the fireplace through the filler neck, especially when using pellets as solid fuel , so that a particularly high degree of filling of the combustion chamber or a pantry of the fireplace can be achieved.

The cross-sectional area of the discharge opening and/or the filling opening should expediently be at least 5000 mm ² , preferably at least 6500 mm ² , and particularly preferably at least 7800 mm ² .

The cross-sectional area of the filling opening is advantageously larger, in particular at least 10%, preferably at least 25%, particularly preferably at least 40%, and particularly preferably at least 70%, than the cross-sectional area of the discharge opening. In this way, a particularly simple introduction of fuel can be achieved.

The cross-sectional area of the discharge opening and/or the filling opening should preferably be at most 200,000 mm ² , preferably at most 150,000 mm ² . As a result, a certain compactness of the device can be achieved.

The body is expediently a sheet metal part and/or a sheet metal construction and/or the body being made of sheet metal. By designing the body as a sheet metal part or as a sheet metal construction, a particularly cost-effective and yet combustion-inhibiting construction of the filling nozzle can be achieved. It is particularly expedient if the body is made of sheet metal material containing iron, in particular steel. As a result, a particularly resilient and at the same time cost-effective construction can be achieved.

Another aspect of the invention can relate to a filling system. This filling system comprises in particular a filling nozzle, advantageously as described above or below, and a cover unit, with the covering unit covering the filling opening of the filling nozzle in a covering state, so that no solid fuel can be introduced into the filling opening, and/or with the covering unit being able to be inserted in a released state of solid fuel into the filler opening of the filler neck allows or permits. Such a covering unit can be, for example, a stopper, in particular made of sheet metal, and/or a covering door. This cover unit can be foldably mounted on the filling nozzle and/or represent a separate, in particular removable, unit. Appropriately, the cover unit is dimensioned such that this covers the filling opening of the filler neck at least partially, preferably completely, in the covering state. In other words, the cover unit of the filler neck system can therefore be designed in such a way that the projections of the filling opening and the covering unit, in particular in the filling direction, are at least essentially congruent and/or exactly congruent and/or the projection of the covering unit surrounds the projection of the filling opening. Essentially congruent is to be understood as meaning that the projection surfaces of the cover unit and the filling opening are congruent with one another within the usual structural tolerances. In other words, a maximum of 5% of the projected area of the cover unit can therefore be formed outside the projected area of the filling opening or vice versa. The cover unit can in particular be partially made of sheet metal or contain sheet metal parts.

In an advantageous embodiment, the cover unit is a door, with the door being expediently fastened to the body of the filling nozzle, in particular so that it can be folded around the transverse axis or the direction of discharge. As a result, a particularly compact design of the covering unit can be achieved, but at the same time it is possible to reliably prevent solid fuel from being introduced into the filling opening during the covering state. The door or the wing of this door or the door leaf of the cover unit is in particular flat, so that a particularly simple and cost-effective construction can be achieved in this way. In order to reduce the risk of fire, the door of the cover unit and/or the cover unit as a whole should be made of a non-combustible material, in particular sheet metal.

Expediently, the cover unit and/or the door of the cover unit can have a locking mechanism which, for example, allows latching so that the cover unit can at least be made more difficult and/or prevented from escaping from the cover state. In this way, in particular, an unintentional opening of the cover unit or uncovering of the filling opening can be prevented.

A further aspect of the invention can relate to a fireplace, in particular a solid-fuel fireplace. Advantageously, this fireplace comprises a combustion chamber, a fireplace body, which extends in particular in a longitudinal direction, and/or a filling nozzle, expediently as described above and below, and/or a filling system, in particular as described above and below. As a result, the advantages described above and below can be realized in a fireplace in a simple manner. The combustion space of the fireplace is expediently the space in which the solid fuel introduced through the filling connection system and/or the filling connection is burned or utilized. In other words, the combustion chamber of the fireplace can therefore be used to utilize or burn the solid fuels introduced into the fireplace through the filling nozzle. The combustion chamber is therefore in particular a solids combustion chamber. The fireplace is limited on the outside by a fireplace body. This fireplace body advantageously extends in a longitudinal direction. The longitudinal direction of the fireplace is therefore in particular that direction in which the fireplace has its largest main dimension and/or in which the length of the fireplace is determined. The body of the fireplace therefore delimits the fireplace perpendicular to this longitudinal direction, for example in the form of brick walls or a concrete body. The fireplace itself can in particular be a fireplace that is independent of the room air. A fireplace that is independent of the room air has the advantage that the oxygen in the room in which the fireplace is located is not used for combustion, so that ventilation of the room can be avoided, resulting in a particularly energy-efficient fireplace. The fireplace therefore expediently has at least one supply air supply, which allows combustion air to be fed into the combustion chamber. Additionally or alternatively, the fireplace preferably has an exhaust pipe, the exhaust pipe allowing combustion gases to be routed out of the combustion chamber. These two lines can be arranged next to one another and/or coaxially with one another.

In an advantageous embodiment, the fireplace has a reservoir, the reservoir being connected directly or indirectly to the discharge opening and/or the combustion chamber, the reservoir being used to store solid fuels, the reservoir being located in particular inside the body, in particular the solid fuel fireplace , is arranged. The reservoir advantageously has a storage volume, the storage volume in particular having a volume which is larger than the volume in the channel and/or the filling nozzle. The storage container of the fireplace is therefore a volume which is oriented or usable in such a way that this solid fuel can be stored. The reservoir is expediently connected directly or indirectly to the discharge opening of a filling nozzle, in particular as described above or below. A direct or indirect connection of the storage container to the discharge opening is to be understood as meaning that solid fuels can reach the storage container from the discharge opening, for example directly or indirectly through a pipeline, for example. The reservoir, in turn, can be connected directly or indirectly to the combustion chamber in order to be able to conduct solid fuel from the storage volume of the reservoir into the combustion chamber. The reservoir is expediently arranged within the fireplace in such a way that solid fuels can get from the reservoir into the fireplace or the combustion chamber due to the force of gravity. This can be achieved in particular by arranging the reservoir above the combustion chamber—in an installed state—in particular in the longitudinal direction and/or in the discharge direction. By providing the reservoir within the body of the fireplace, a fireplace that saves particularly space can be achieved, which can nevertheless reliably achieve or ensure utilization of solid fuels in the combustion chamber over a certain period of time.

The storage container expediently has a size or storage volume in the range from 10 to 50 liters, preferably from 12 to 30 liters and particularly preferably from 15 to 20 liters. Under the size of the reservoir is to be understood as the storage volume of the storage container or the storage volume, which is available for storing the solid fuel. If the size of the storage container is in the range of 10 to 50 liters, a particularly compact and space-saving fireplace can be achieved. If the volume or size of the storage container is in the range of 12 to 30 liters, the fireplace can be supplied for at least 24 hours of burning and/or for at least 12 hours of burning, so that the comfort of the fireplace is increased can, because a continuous filling of the reservoir with solid fuel can be prevented by such a dimensioning, but at the same time a particularly compact and space-saving fireplace can be achieved. If the volume or the size of the storage container is in a range of 15 to 20 liters, a particularly good suitability of the storage container for storing or storing pellets can be achieved.

The fireplace body is expediently a concrete body. A concrete body is to be understood as meaning that at least 30%, preferably at least 50% and particularly preferably at least 70% and particularly preferably at least 80% of the fireplace body consists or is made of concrete. In other words, the body of the fireplace and/or its outer surrounding walls can be made of concrete in part, preferably for the most part. In this way, among other things, a particularly cost-effective design of the fireplace can be achieved. In addition, this can also increase the risk of fire and the insulating effect.

Advantageously, the projection of the ejection opening in the longitudinal direction and/or in the ejection direction is surrounded by the projection of the fireplace body in the longitudinal direction and/or in the ejection direction. In other words, when viewing the fireplace in the longitudinal direction and/or in the exit direction, the exit opening can be arranged completely within the (projected) border of the fireplace body. This allows a particularly compact and easy filling of the fireplace with solid fuel can be achieved.

Alternatively or additionally preferably, the insertion opening can be designed in such a way that the projection of the insertion opening in the longitudinal direction and/or in the exit direction is surrounded by the projection of the fireplace body in the longitudinal direction and/or in the exit direction. In other words, the insertion opening can therefore also extend completely within and/or to the outer limit of a fireplace body. A particularly compact configuration of a fireplace can also be achieved in this way.

Particularly preferably, both the projection of the discharge opening and the projection of the insertion opening are arranged within the projection of the fireplace body in order to further increase the compactness of the filling system.

In an alternative or additionally preferred embodiment of the fireplace, the discharge opening is arranged in the longitudinal direction or in the discharge direction above the storage container and/or the combustion chamber and/or the storage container is arranged in the longitudinal direction or in the discharge direction above the combustion chamber. Above, in particular in the longitudinal direction or in the direction of discharge, is to be understood that in an installed state there is at least a certain distance opposite to the direction of the vector of the acceleration due to gravity in the longitudinal direction or in the direction of discharge, so that gravity prevents the transport of solid fuels from the discharge opening into supports the reservoir and/or the combustion chamber or fuel reservoir into the combustion chamber and/or only to a limited extent. In other words, arranging it “above” means that gravity can be used to fill the reservoir and/or to fill the combustion chamber.

The fireplace or the storage container expediently has a connecting piece, the filling piece being fastened to the combustion chamber or the storage container, in particular directly or indirectly, via the connecting piece is, wherein the filler neck advantageously protrudes into the connection piece, and / or wherein a dust seal can be provided between the filler neck and connection piece. The connection piece of the fireplace or the combustion chamber or the storage container serves to connect the filling connection piece or the discharge opening of the filling connection piece to the connection piece. In other words, the connection piece of the fireplace or the combustion chamber and/or the storage container is therefore a connection piece for docking the filling connection piece. In order to achieve a particularly secure installation of the filler neck or the filling neck, the filler neck should extend at least partially into the connection piece. In order to achieve a particularly high sealing effect, a seal, in particular a dust seal, should be provided between the filling socket and the connection socket. This seal can advantageously be made of rubber and/or of a metallic material, in particular copper.

Another aspect of the invention may relate to a fireplace system. Such a fireplace system comprises in particular a fireplace, advantageously as described above and/or below, and a mounting frame, the mounting frame being designed in such a way that it surrounds or can surround the insertion opening and/or the filling opening is or can be supported on the mounting frame and /or is inserted or can be inserted into the mounting frame. The mounting frame serves in particular to be or to be embedded in a wall of a building and/or a side wall of the body of the fireplace in order to limit the masonry or the opening of the wall, for example. The mounting frame or its cross-sectional area is advantageously designed in such a way that the insertion opening of the filler neck can be inserted into it. It is particularly expedient if the mounting frame is dimensioned and designed in such a way that that part of the body of the filler neck which forms the filling opening can be or is supported on the mounting frame. In other words, this can mean that the filling opening is supported on the mounting frame in a mounted state. The mounting frame can expediently form a click or latching system together with the covering device, in order to be able to latch or close the opening of the mounting frame with the covering unit. The mounting frame is expediently made of metal in order to reduce the risk of fire.
