Definitions

  • the invention relates to a warm air fireplace with a combustion chamber which is surrounded by side walls, the combustion chamber is accessible via a front opening, which can be covered by a height-adjustable disc guided in a stationary frame.
  • the combustion air is supplied through a combustion chamber opening on the front, which can be closed more or less as required by a height-adjustable, usually transparent disc.
  • a combustion chamber opening on the front which can be closed more or less as required by a height-adjustable, usually transparent disc.
  • the combustion air should be regulated and metered for low-pollutant combustion with high efficiency.
  • With the disc closed this requires an adjustable combustion air supply, bypassing the usual front opening of the combustion chamber. Even when the disc is closed, it cannot be avoided that foreign air from the front can enter the combustion chamber.
  • the object is to be achieved, in a warm air fireplace of the type mentioned, to seal the height-adjustable disc in an airtight manner relative to the combustion chamber, in order to avoid an undesired supply of external air to the combustion zone and, on the other hand, to enable the disc to be easily moved in height if necessary.
  • This object is achieved in that - bypassing the combustion chamber opening which can be covered by the disc - there is at least one supply channel for the combustion air to be supplied to the combustion chamber, the disc is movably supported transversely to its broad side, and there are pressing elements with which the disc in its closed position can be pressed tightly against the stationary frame and spring means are available for lifting the pane from the stationary frame in the relaxed state.
  • the hot-air fireplace 1 contains side walls 2 which are surrounded by an outer steel jacket.
  • the combustion chamber 2 is closed on three sides and open on the front.
  • This front-side combustion chamber opening can be covered by a height-adjustable disk 17.
  • the disc 17 is provided with a disc frame 4 which is guided in a stationary frame 9.
  • a counterweight not shown in the drawing, interacts with the disk 17, so that the disk 17 together with its frame 4 can be raised or lowered with little effort.
  • connection opening 5 On the side for the supply of fresh air to be heated.
  • two hot air outlet openings 6 and a chimney opening 7 are provided for the extraction of the exhaust gases.
  • slot-like combustion air openings 8 at the front below the combustion chamber floor 13, which open laterally into the interior of the combustion chamber 3 through pipelines or channels, bypassing the front opening.
  • a throttle device interacts with these combustion air openings 8. This contains, for example, a linearly movable slide 21 with throttle openings 23. This throttle device can either be adjusted manually by a hand lever 28 or by a motor. When the disk 17 is closed, this is the only combustion air supply to the combustion chamber 3.
  • the throttle device can be controlled and regulated in time so that the combustion air supply is adapted to the ongoing combustion process.
  • the pane 17 is preferably made of fireproof glass and is transparent, so that it allows an insight into the combustion chamber.
  • the disk 17 is provided with a heat insulation layer along the edge.
  • the pane frame 4 preferably has a U-shape in cross section, the open side being directed towards the interior of the combustion chamber 3.
  • a sealing strip 16 made of refractory material is inserted into the pane frame 4.
  • the pane 15 can also be designed to be pivotable relative to the pane frame 4 by means of hinges in order to facilitate cleaning.
  • the height-adjustable pane frame 4 slides into two vertical ball rails 10, which are each arranged to the side of the pane frame 4.
  • the stationary frame 12 contains four legs 14 arranged in a rectangle or square, which extend at right angles to the pane surface and which are intended to interact with the sealing strip 16 surrounding the pane frame 4.
  • the sealing strip 16 could also be designed as a metal spring, which results in a tight seal due to the abutment on the end face of the legs 14.
  • Fig. 2 the window frame is shown in the relaxed - ie non-sealing - state, with an intermediate space 25 between the sealing strip 16 and the end face of the legs 14.
  • pressure elements are present, which are described in more detail below.
  • Each of these two rods 18 contains at its upper end a radially protruding shoulder in the form of a nose 20 and at the lower end a radially projecting tab 22.
  • a pull rod 24 engages in each of the two tabs 22, each of which is articulated with a common rotating member one stored in the stationary frame
  • Turntables 26 are connected.
  • the turntable 26 is non-positively attached to a hand lever 28 with which a pivoting movement can be carried out. If this pivot lever 28 is pivoted from the position in FIG. 2 to the right into the position shown in FIG. 3, this causes the two rods 18 and with them the lugs 20 to rotate in opposite directions.
  • These lugs 20 then each press against a stop 30 of the window frame 4, whereby this is moved transversely to its broad side in the direction of arrows A.
  • Characterized the sealing strip 16 is pressed against the front end of the leg 14, so that a seal is made. In this sealing position of the disc 4, combustion air can only get into the interior of the combustion chamber 3 via the throttle openings 8.
  • the window frame 4 is pressed into the relaxed position by means of compression springs 32 when the lugs 20 are lifted off the stop 30.
  • compression springs 32 There are a plurality of spaced apart compression springs 32 which each surround a bolt 34.
  • the threaded end of these bolts 34 is screwed into a bar provided with threaded holes or a nut 19 of the disk frame 4.
  • the other bolt end provided with a head 35 is held axially displaceably in a bush 36.
  • FIG. 5 shows an embodiment variant in which a motor drive for the pressing members is present instead of the hand lever 28.
  • An electric motor 40 is connected to the turntable 26 via a drive rod 42.
  • the remaining structure corresponds to that according to FIGS. 2 and 3.
  • a control device interacts with the height-adjustable pane frame 4 in such a way that the pane frame 4 can only be pressed or relaxed in its closed position.
  • there is an actuating rod 46 the upper end of which is intended to cooperate with the window frame 4 and which is loaded by a spring 48.
  • the lower end interacts with an electrical switch 50, which in turn causes the motor to receive power only when the window frame 4 is in its lowest, ie closed, position. This prevents the disk 4 from being blocked in intermediate positions.
  • Fig. 6 shows a variant of the sealing members.
  • a leaf spring 16 'made of flexible metal is present, which protrudes into the frame 14 and is fastened to the disk 17 by an intermediate layer 39.
  • the leg 14 bears against the resilient leaf spring 16 'and thereby causes a seal.
