Definitions

  • the present invention relates to a central heating and cooking stove with a filling shaft and at least one further shaft, which is connected downstream in the flue gas stream and in which an internal heat exchanger is accommodated, the flue gas inlet leading into the internal heat exchanger and into one leading directly to the chimney or to an external heat exchanger Discharge opening can be closed entirely or partially by a regulating member.
  • cookers are combined with a built-in heat exchanger, which is to supply the hot water for central heating, for example.
  • Many of these combined systems are also connected to an external, i.e. H. Coupled outside the cooker arranged second heat exchanger, in which the residual heat of the combustion gases escaping from the cooker is used.
  • an external heat exchanger can be, for example, a tiled stove, an air heater, a smoke chamber or the like.
  • Optimal flue gas routing in accordance with the respective heat exchanger output is therefore of great importance, both in the event that an external heat exchanger (tiled stove) is connected downstream of the stove, and in general for adapting the flue gas temperature to the optimal one for the chimney Conditions.
  • the cooker shown in FIG. 1 with no essential details has an outer jacket 1, which is provided with fresh air inflow openings 2 in a known manner.
  • the walls of the outer casing 1 are provided on their inner surfaces with water chambers 3, 4 and 5, and the interior is subdivided by further water chambers 6 and 7 arranged within the cooking range in such a way that a filling shaft 8, an intermediate shaft 9 and a further shaft 10 are formed .
  • the filling shaft 8 has in its lower part an ash slide 11 and above it a grate 12 which is supported on the one hand on a flange 13 and on the other hand on the cheek of a T-profile 14.
  • the heat exchangers designated 17 are arranged and, adjacent to them, a discharge opening 18, which opens into a vertical discharge duct that discharges the flue gases to the outside.
  • a cooking grate is arranged in the filling shaft 8 above the heating grate 12.
  • the heating grate 12 could optionally also be made height-adjustable.
  • the structural design of the internal heat exchanger 17 arranged inside the shaft 10 is of secondary importance in the present context.
  • water chambers are also used here, which are provided with metallic ribs to enlarge the surface exposed to the flue gases.
  • the outer jacket of the cooker designated in its entirety by 1, is only partially shown in the drawing for reasons of better clarity, and in particular the upper cover is missing from the drawing, which of course extends over the entire upper region of the cooker and includes, among other things, the hotplate .
  • a closure strip 20 which is fixedly attached to the water chamber 6 and which thus directly covers the cover prevent the flue gases from the intermediate shaft 9 into the discharge opening 18.
  • a regulating flap 21 is arranged on the water chamber 3 in the area of the flue gas inlet to the heat exchanger 17 in such a way that it can be pivoted about a horizontal axis 22.
  • FIG. 1 shows the regulating flap in its open position, while according to FIG. 2 it prevents the flue gases from entering the internal heat exchanger 17.
  • the regulating flap 21 has on its edge facing the discharge opening 18 a circular cheek 23 which is pulled up when the regulating flap 21 is opened and thus also closes the discharge opening 18 from the side of the regulating flap 21.
  • the entire amount of flue gas thus flows through the internal heat exchanger and then reaches a horizontal, lower exhaust duct 24.
  • the direct access to the exhaust opening 18 is closed in this position of the regulating flap 21.
  • the regulating flap 21 is folded down into its horizontal closed position, the flue gases rising through the intermediate shaft 9 can no longer make their way through the internal heat exchanger 17.
  • the closure cheek 23 has released direct passage through the exhaust opening 18 into the exhaust duct (FIG. 2), so that the hot flue gases now bypass the internal heat exchanger 17 directly to the chimney or an external heat exchanger, for example a tiled stove , are forwarded.
  • Figures 1 - and 2 of the drawing only show the two extreme positions of the regulating flap 21 and the closing cheeks 23. Between these two extreme positions, of course, any number of intermediate positions can be set as required.
  • Fig. 1 the flap 21 is indicated in its closed position with broken lines. Accordingly, the fully drawn arrows A also show the flue gas path when the regulating flap is open, the interrupted arrows B show the flue gas path when the regulating flap is closed.
  • the closed position of the regulating flap is shown with the associated flue gas duct. This position corresponds primarily to the cooking mode or generally to a mode with low heating output, which means a higher flue gas temperature.
  • the regulating flap 21 - and thus also the closure cheek 23 - can, according to a preferred embodiment, be actuated by an actuator, which in turn is controlled by a regulator.
  • This controller is connected to a temperature sensor arranged in the flue gas stream of the chimney and thus regulates the position of the regulating flap 21 and the closure cheek 23 as a function of the flue gas temperature prevailing in the chimney. This allows the flue gas temperature in the chimney to be kept constant within a certain, desired range.

Claims (3)

1. Fourneau de cuisine et de chauffage central comportant un carneau de remplissage (8) et au moins un autre carneau (10) qui suit le premier dans le flux des fumées et dans lequel un échangeur de chaleur interne (17) est installé, l'entrée des fumées dans l'échangeur de chaleur interne (17) ainsi que dans une ouverture d'évacuation (18) menant directement à la cheminée ou à un échangeur de chaleur externe, pouvant être fermée entièrement ou partiellement par un organe de régulation (21, 23), caractérisé en ce qu'un carneau intermédiaire (9) destiné à guider les fumées vers le haut est disposé entre le carneau de remplissage (8) et l'échangeur de chaleur interne (17) et est raccordé par une ouverture d'évacuation inférieure (16) au carneau de remplissage (8), étant entendu que ladite ouverture d'évacuation (18) est fermée du côté du carneau intermédiaire et que l'organe de régulation (21, 23) est un volet régulateur pivotant (21) qui, du côté adjacent à l'ouverture d'évacuation (18), présente une joue de fermeture (23), le tout étant agencé d'une manière telle que la joue de fermeture (23) ouvre le passage direct des fumées dans l'ouverture d'évacuation (18) à mesure que le volet régulateur (21) ferme l'entrée des fumées dans l'échangeur de chaleur interne (17).
2. Fourneau de cuisine et de chauffage central (1), caractérisé en ce que l'échangeur de chaleur interne (17) et le canal d'évacuation disposé en dessous de l'ouverture d'évacuation (18) sont adjacents et installés dans un carneau (10) parallèle au carneau de remplissage et s'ouvrent tous deux dans un canal d'écoulement horizontal inférieur (24).
