Definitions

• firebox closing devices or fireplace doors are already known from various publications. These firebox closing devices are also formed by a frame and a door pivotably inserted therein.
• secondary air control devices are mostly integrated in the basic structure of the door or in the further structure of the heating fireplace or the furnace.
• attempts are often made to solve the problem of contamination of the inside of the door by combustion residues, particularly disadvantageously for doors which have a viewing window made of high-temperature-resistant glass, etc.
• the invention is based on the object of providing a combustion chamber closing device for a heating system in which, on the one hand, a tight closing of the combustion chamber and, on the other hand, a position of the combustion chamber closing device for an adequate supply of the door area and combustion chamber with combustion air is achieved.
• the surprising advantage here is that the supply of combustion air to the combustion chamber is made possible by a simple, straight-line movement of the combustion chamber closing device or the door and that the closed position of the door or an air gap between the anchoring frame and the door-forming position can be kept fixed via at least one locking device.
• This displacement of the door is made possible by guideways which are arranged on the anchoring frame or integrated therein.
• a further advantage results from the fact that the door is pivotable in both positions relative to the anchoring frame, which is arranged in an opening of a heating fireplace, in order to enable the door to be opened at any time and thus access through the loading opening to ensure the combustion chamber.
• such a firebox closing device is intended to make it possible for the air gap between the door or the sealing element and the anchoring frame to be of different sizes all around.
• the possible change in the position of the door in the vertical plane also makes it possible to change the supply of combustion air at any time. Accordingly, a change in the air gap in the upper or lower area of the door enables optimal combustion to be achieved in every stage of the burn.
• FIG. 1 shows a fire chamber closing device according to the invention for a heating system with an anchoring frame and a door and a locking device or pivoting arrangement arranged between them, in a top view, in section and in a schematically simplified representation;
• FIG. 2 shows a representation according to FIG. 1 with a door located in another position, in a top view, in section and schematically simplified
• the firebox closing device 1 in turn now consists of a frame-like or portal-like anchoring frame 5, which is inserted in an opening 6 of the heating fireplace 4 so that it cannot move.
• the loading opening 3 of the anchoring frame 5 is now through a door 7, which in this example is formed from an outer frame 8 and an inner frame 9.
• a filling 10 in the form of a viewing window 11 on the side of the door facing away from the anchoring frame 5, which enables a view into a combustion chamber 12 of the heating fireplace 4.
• the door 7 can also be formed by a single casting, it being possible for various insert or attachment parts made of metal or ceramic to be arranged instead of the viewing window 11.
• the anchoring frame 5 now consists of three legs, preferably running at right angles to one another, these being referred to as outer legs 13, inner legs 14 and a connecting leg 15 connecting them, the circumferential inner legs 14 delimiting the loading opening 3 in its extent.
• a sealing arrangement 17 in the form of a sealing element 18 is arranged for the air-tight or smoke-tight closing of the loading opening 3.
• pivot arrangement 19 is thus formed over a height 21 of the combustion chamber closing device 1 with two hinges 22 in order to enable the door 7 to pivot.
• hinges 22 now have two legs 23, 24, the leg 23 being slidably mounted or held on the outer frame 8 of the door 7 and the leg 24 in the adjustment arrangement 20.
• the adjusting arrangement 20 is in turn formed from two guideways 25 which run in a plane perpendicular to a plane formed by the loading opening 3, these two guideways 25 encompassing the leg 24 in such a way that a displacement of the leg 24 in the longitudinal direction of the guideways 25 is made possible, but a movement in another direction is avoided.
• the adjustment arrangement 20 can be formed by a slide bearing, wherein the leg 24 can be moved linearly in the guideways 25. As a result, however, the weight of the door 7 can cause the leg 24 to tilt relative to the guide tracks 25. For this reason, it is advantageous to implement the adjustment arrangement 20 by means of a roller bearing, as a result of which a trouble-free displacement of the door 7 relative to the anchoring frame 5 is ensured over a long period of time.
• This arrangement according to the invention of the adjusting arrangement 20 or of the guide tracks 25, from which the adjusting arrangement 20 is formed, makes it possible to move the door 7 from a first position, which closes the loading opening 3 via the sealing arrangement 17 in an airtight and smoke-tight manner, into an approximately parallel position for this purpose, and at least in some areas an air gap 26 between the inner leg 14 of the anchoring frame 5 and the door 7 is designed to be adjustable, as shown in FIG. 2.
• the arrangement of the pivot arrangement 19, which is formed by the hinges 22, makes it possible to pivot the door on the one hand in the first position and on the other hand in the second position forming the air gap 26.
• the guideways 25 for linearly movable mounting of the leg 24 of the hinge 22 on the outer frame 8 of the door 7 or on the door 7 itself.
• these guideways 25 for linearly movable reception of the leg 24 in the outer frame 8 of the door 7 or in the door 7.
• Such a design of the adjustment arrangement 20 or of the swivel arrangement 19 means that the fixed leg 23 of the hinge 22 is arranged on the connecting leg 15 so that it cannot move and the relative movement is made possible in that the door 7 or the outer frame 8 of the door 7 is placed on the further leg 24 of the hinge 22 can slide over the guideways 25.
• locking levers 27 are now arranged between the door 7 and the anchoring frame 5.
• These locking levers 27 are pivotally mounted on the outer frame 8 of the door 7 via pivot bolts 28 such that the locking levers 27 run parallel to the anchoring frame 5 or to its connecting leg 15.
• positioning pins 30 extending perpendicularly in the direction of the outer frame 8 of the door 7 are arranged on the inner surface 29 facing the door of the connecting leg 15 of the anchoring frame 5.
• the locking levers 27 now have at least two groove-shaped recesses 32, 33 along their longitudinal extension and between the pivot bolts 28 and their end regions 31 facing the inner leg 14, which recesses engage around the positioning pins 30 in regions when the door 7 is locked.
• Sealing element 18 can be arranged clamped in the end regions of the outer frame 8 or inner frame 9 of the door 7 assigned to the inner legs 14 of the anchoring frame 5 and can protrude from an end face 36 thereof. If the door 7 is now in its first position, the sealing element 18 rests on an inner surface 37 of the inner leg 14 facing the door 7 and is held in this first position by a lock which is made possible by locking lever 27. This fixed mounting results from the gripping of the recesses 33 around the positioning pin 30, this fixing being able to be released again by a user without great effort.
• a second recess 32 is arranged on the locking lever 27 facing away from the pivoting arrangement 19 in the end region 31 of the locking lever 27 facing the anchoring frame 5, which limits the relative movement of the door 7 after reaching the second position forming the air gap 26.
• a stepless adjustment of the door 7 with respect to the loading opening 3 is possible between the two recesses 32, 33 on the locking lever 27, as a result of which the expansion of the air gap 26 or the supplied combustion air can be adjusted - as shown by the arrow 35 - is made possible.
• a too large relative movement of the door 7 with respect to the anchoring frame 5 can also be caused by a Stop 38, which engages in a groove extending in the longitudinal direction of the leg 24, as is indicated in FIG. 2 by dashed lines.
• the hinges 22 or the legs 23 of the hinges 22 rotatably via a bolt on the door 7 or the outer frame 8 of the door 7, in order to position the door 7 in its second position in the vertical position which forms the air gap 26 Training direction swivel.
• the door 7 in the second position forming the air gap 26, the door 7 can form a differently sized air gap 26 in the region of an upper end edge 39 of the sealing arrangement 17 and in the region of a lower end edge 40 of the sealing arrangement 17.
• the door 7 can be designed as a one-piece cast iron part his.
• an insert part or an attachment part which can be made of metal, ceramic or another heat-resistant material, can be arranged in the area in which it is possible to arrange a viewing window 11.
• FIGS. 1, 2, 3 can form the subject of independent solutions according to the invention.
• the relevant tasks and solutions according to the invention can be found in the detailed descriptions of these figures.
