Definitions

  • the invention relates to a hot-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 pane guided in a stationary frame, that - bypassing the one that can be covered by the pane Combustion chamber opening - 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 pressure elements are available with which the disc can be pressed tightly against the stationary frame in its closed position.
  • 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. It shows, however, that the combustion air in the combustion chamber should be regulated and metered for low-pollutant combustion with high efficiency. On the one hand, this requires a closed disc and a combustion air supply, bypassing the usual front opening of the combustion chamber. Even when the disc is closed, however, it cannot be avoided that foreign air that interferes with the front enters the combustion chamber.
  • a fireplace with a front height-adjustable pane is known, means being available to press the pane tightly against a stationary frame.
  • the air required for the combustion process is fed to the combustion chamber separately.
  • a heat exchanger is available for the heat release into the surrounding space, whereby an outer and an inner shell are present.
  • For pressing the window onto the stationary frame in the lower end position there are cranked guide rails on both sides as roller guides for the window frame. This configuration requires a relatively large amount of constructive means.
  • the fireproof seal rubs against the stationary frame during the seal movement, which can wear or damage it.
  • CH-A-675 467 shows a fireplace in which the fire opening can be sealed off by means of a vertically sliding window.
  • the air required to maintain the combustion process is fed to the fireplace in a separate duct. Sealing takes place without movement of the window transversely to its broad side by sloping ramp plates against which the seal comes to rest in the closed position.
  • the object of the invention is to improve a warm air fireplace of the type mentioned at the outset in such a way that the height-adjustable disc can be sealed relative to the combustion chamber with comparatively simple means and a smooth height displacement of the disc is possible without friction of the seal on stationary parts .
  • first pressing members are present, which radially project from a rotatable, vertical rod arranged in the area near the edge of the disc and which cooperate with second pressing elements in the lateral region of the disc frame, the lower rod ends of which are each connected in an articulated manner via connecting elements to a common rotating element mounted in a fixed part and effective springs are provided transversely to the broad side of the pane 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 3 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 12.
  • 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 on 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 be adjusted either manually or by motor. When the disc 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 disc 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 17 can also be designed to be pivotable about a vertical axis relative to the pane frame 4 in order to facilitate cleaning.
  • pane frame 4 can be sealed against the stationary frame 12 and thus a supply of unwanted external air to the combustion chamber 3 is avoided, pressure elements are available with which the pane 17 or the pane frame 4 can be pressed tightly against the stationary frame 12, such as this is evident from Figures 2-4.
  • 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.
  • 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 provided, which are described in more detail below.
  • Each of these two rods 18 contains at their upper end first pressing members in the form of a radially projecting nose 20 and at the lower end a radially protruding tab 22.
  • a pull rod 24 engages in each of the two tabs 22, each of which is articulated with a common rotating member Form of a 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 a counter-pivoting movement of the two rods 18 and with these of the lugs 20.
  • These lugs 20 then each press against second pressing members in the form of stops 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 stops 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 window 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 provided 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.
  • 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 cooperates with an electrical switch 50, which in turn causes the motor to receive power only when the window frame 4 is in its lowermost, that is to say closed, position. This prevents the disk 4 from being blocked in intermediate positions.
  • FIG. 6 shows an embodiment variant of the sealing members.
  • a leaf spring 16 'made of flexible metal is present, which protrudes into the frame 4 and is fastened to the pane 17 by an intermediate layer 39.
  • the leg 14 bears against the resilient leaf spring 16 'and thereby causes a seal.
