Definitions

  • the invention is based on a method and one Device for removing gas bubbles from a double-walled water-cooled combustion chamber one Water heater according to the genus of the independent Main claims.
  • EP 595 945 B1 proposes to Removal of gas bubbles from a water-bearing Double jacket of a heating shaft a ventilation tube or use a vent valve. So that can Gas bubbles that have accumulated in the double jacket after be drained outside. This procedure requires additional components, which means the manufacturing costs for one such water-bearing double jacket can be increased. Of the Use of a vent valve also increases the Installation height of the heating shaft in a water heater.
  • inventive method and the inventive Device with the features of the main claims have the Advantage that, without additional components, gas bubbles located in the double-walled water-bearing combustion chamber carried away by the injector effect become. This will cause the combustion chamber to overheat prevented; Vapor formation and boiling noises avoided.
  • the contour is to reduce the flow resistance the circumferential weld seam in the upper area of the Combustion chamber sectionally formed in a circular arc.
  • the double-walled combustion chamber has two side walls and a rear wall, which together is a U-shaped unit form, with the upper area in the rear wall of the Combustion chamber is formed.
  • FIG. 1 shows a perspective view a combustion chamber for gas-fired water heaters with a lifted upwards as a slat block with passed through water pipes trained heat exchanger and one detachable with the side walls of the combustion chamber connectable front wall
  • Figure 2 on an enlarged scale a vertical section through the side wall of the Combustion chamber and a partial section through the attached
  • Heat exchanger according to Figure 1 and Figure 3 is a plan view one of two welded wall plates existing circuit board, which after welding to a die Rear wall and the two side walls of the combustion chamber forming U-shaped part is bent.
  • the water heater has a combustion chamber 10 with a Rear wall 12 and two integrally connected to this Side walls 14, 16 on which a front wall 18 is detachable is attached.
  • the combustion chamber 10 is from above Heat exchanger 20 can be put on, as a lamella block performed water pipes is formed.
  • the sidewalls 14, 16 of the combustion chamber 10 are towards the upper end edge open recesses 22 provided to fit the Serve reception of the heat exchanger 20.
  • the combustion chamber walls consist of two adjacent and welded together Wall plates 38, 40 made of stainless steel, the molded one Have sheet metal areas 42, 44, between which a channel system 46 for a heating water flow cooling the combustion chamber 10 is formed.
  • the channel system 46 is produced by that the wall plates 38, 40 initially still in their essential flat initial shape through straightforward Welds 48 are joined together and only afterwards the channel system 46 by molding the between the Weld seams 48 of sheet metal areas 42, 44 by means of a pressure between the wall plates 38, 40 imported fluid working fluid is formed.
  • the front wall 18 is through the formation of hydraulic connection connections of the remaining wall parts 12, 14, 16 of the combustion chamber 10 detachable without the one used to cool the combustion chamber Heating water flow must be interrupted. For this, e.g. from a copper tube bent connecting elements 56, 57 of Front wall 18 with flexible hose lines 70, 72 connected, which as part of the line sections Form the heating water circuit.
  • the channel system 46 in the rear wall 12 and the side walls 14, 16 is according to the settlement of these wall parts according to the figure 2 by a self-contained circumferential weld seam 48a and ten elongated single weld seams 48b-k were formed.
  • a self-contained circumferential weld seam 48a and ten elongated single weld seams 48b-k were formed.
  • there are four in the side wall 16 Individual channels 46a, the edge of a chamber 46b are interconnected and open into a chamber 46c.
  • Five parallel individual channels 46d lead from the latter Rear wall 12 continues into a chamber 46e, which has four Individual channels 46f in the side wall 14 with an outer Chamber 46g is connected.
  • This Effect is also favored in that the Total cross section of the flow channels 46d in the rear wall 12 is larger than the total cross section of the respective Flow channels 46a and 46f in the side walls 14, 16, with which the flow rate of the heating water in the Rear wall 12 is smaller than the flow rate in the side walls 14, 16.
  • the front wall 18 also becomes 46h in the uppermost channel Avoiding the air bubble accumulation Flow rate of the heating water towards the exit increased by the four lower channels 46h in pairs are flowed through in parallel, after which the Heating water flow only through the 48p through the welds and 48l formed channel is led to the output.
