Definitions

  • the invention relates to a hot water instantaneous water heater in which, in a boiler through which water flows, an oscillating fire unit arranged on a cover is immersed, which is provided by an air cylinder containing an intake silencer and a combustion chamber connected to the intake silencer via a mixing tube adjoining this vibrating tube, an exhaust gas silencer into which the vibrating tube opens, and is formed by an exhaust gas pipe leading away from it.
  • Such water heaters are known (DE-C-19 22 650). In this known arrangement, however, it is not guaranteed that the entire water flowing through the container between the water supply and water drainage is actually optimally heated; Furthermore, the exhaust muffler surrounding the intake silencer, as it were, like a ring, prescribes a certain complexity of the installation space with regard to the diameter of the entire arrangement; Furthermore, a relatively space-consuming arrangement must also be chosen in order to obtain the length of the oscillating tube necessary for a stable oscillation process.
  • the object of the invention is accordingly to develop a hot water heater of the type mentioned so that the most effective use of the heat generated in the oscillating fire unit is guaranteed.
  • a space-saving, compact construction is to be ensured, in which the individual components are nevertheless maintenance and assembly-friendly, i.e. are arranged easily and easily accessible.
  • the exhaust silencer is cylindrical and is arranged vertically next to the air cylinder and its size is approximately equal to the size of the air cylinder, that the combustion chamber is arranged above the air cylinder and the oscillating tube in a horizontal plane starting from the combustion chamber, with the end of the oscillating tube being slightly inclined towards the exhaust silencer with respect to this plane, and that the entire oscillating fire unit in the boiler through which the water flows is essentially between the water supply at the lower end of the boiler and the water discharge at the upper end of the Boiler is arranged.
  • the essence of the label is that the air cylinder (with Ans eye muffler) and the exhaust muffler are arranged vertically next to each other, that the combustion chamber is arranged above that the oscillating pipe runs in the plane above the two cylinders and that the entire arrangement practically "hangs" on the cover so that it comes out of the boiler with it can be removed.
  • This entire compact unit is also located in the boiler between the water inlet on the bottom and the outlet at the top of the boiler below the lid. An extremely compact construction is thus achieved overall.
  • the heating is optimal in that the strongest heating - namely through the entire length of the vibrating tube and the combustion chamber - takes place shortly before the water drain, the water being preheated by the other assemblies also immersed in the boiler before it reaches this point has been.
  • all elements heated in any way by the oscillating fire system - including the silencer - contribute to the heating of the water.
  • the fact that all these elements are surrounded by water results in further sound absorption.
  • the assemblies are also arranged in relation to one another in such a way that the water cannot find its way to locations within the boiler where it does not necessarily have to come into contact with elements heated by the oscillating fire system.
  • the assembly of the two cylinders with the combustion chamber lying above them and the arrangement of the vibrating tube in one plane lead to a kind of forced guidance of the water in the sense of optimal heating. This results in an optimal use of the heating value of the fuel; the exhaust gas is discharged practically lukewarm. The efficiency is over 99%.
  • the invention further relates to various advantageous developments.
  • the boiler 1 is formed by a boiler 1 with a bottom 2, which is seated on a device box 3. It is insulated with an insulating layer 4. On the underside of the boiler, this water is supplied via a water supply 5. When using the hot water instantaneous water heater in the closed water circuit, this is the so-called return. The water rises in the boiler after heating, as described below, and exits the boiler through the water drain 6, the so-called flow.
  • the boiler 1 is covered at the top by a cover 7, which is sealed on the boiler 1 with the aid of seals 8.
  • the cover 7 is provided with an insulating layer 4 '.
  • An oscillating fire immersion heater assembly 9 is now arranged on the cover 7 from above into the boiler 1.
  • the air cylinder 10 into which the pipe socket 11 protrudes, which is connected via an elastic hose piece 12 to a further pipe socket 13 fixedly arranged in the cover 7 in order to introduce air into the air cylinder from the space 14 above the cover 7; an intake silencer 15 into which the air from the air cylinder 10 enters through inlet openings 16; a check valve 17, via which air from the intake silencer 15 enters the mixing tube 18; a gas supply 19, to which the gas serving as fuel is supplied via line 20 and from which it exits into the mixing tube 18; a spark plug 21 for initiating the combustion process at the start of the oscillating fire combustion, to which the high voltage is supplied via a line 22; a combustion chamber 23 adjoining the mixing tube 18, in which the gas / air mixture is deflagrated; the “pretzel-shaped (see also FIG.
  • connection of the connecting line 31 and the exhaust line 32 is detachable via a screw connection 33.
  • the lines 20, 22 are detachably connected to the lines 20 ', 22' and these connections (not shown) are also located above the cover 7 in the for the Fittings and controls provided space 14 within the cover 35.
  • the screw connection 33 is designed such that it creates a detachable connection of the exhaust pipe 32 with the cover 7, so that the cover 7 can be removed when this connection is released.
  • the exhaust pipe 32 is firmly inserted in the bottom 2 of the boiler 1 on the underside.
  • a riser pipe 36 is also fixedly connected to the cover 7 by means of a detachable screw connection 37. When this screw connection is loosened, the cover 7 can be removed from the riser pipe 36.
  • the line 20 'for supplying the gas, which is connected to the line 20, and the line 22' for supplying current to the spark plug 21, which is connected to the line 20, are to the connections in the equipment box 3 passed through.
  • Fresh air is also drawn in through the riser pipe 36. This is done from the equipment box 3, into which the fresh air can enter dust-free through the slots 38 and (not shown) air filter.
  • the cover 7 with the entire oscillating fire immersion heater assembly 9 can be removed, so that any maintenance work or the like can be carried out on the entire assembly in an extremely simple manner.
  • the further fittings are then still provided within the cover 35.
  • the cold water enters the boiler 1 from below through the water supply 5 and flows around the air cylinder 10, the exhaust gas cylinder 26 and furthermore the combustion chamber 23 and the oscillating tube 24. It thus makes a considerable contribution to further noise reduction in addition to the mufflers .
  • the water is then heated above the air cylinder 10 or the exhaust gas cylinder 26 by the heat given off by the vibrating tube 24 and then emerges somewhat above this area through the water discharge 6.
  • Vibration damping takes place through the suspension of the air cylinder and exhaust gas cylinder on the elastic hose sections 12 and 28, respectively. Sound attenuation takes place through the silencers and through the arrangement of the various lines, for example 22, 39, 20, 20 ', 22' in flow-through pipes. A further vibration damping takes place in that the entire arrangement stands on rubber feet 41.
  • the arrangement of the oscillating tube 24 can be seen in particular from FIG. 2; its length is determined by the resonance conditions of an oscillation of 100-125 Hz; it is therefore not variable.
  • the arrangement shown solves the problem of arranging a vibrating tube particularly cheaply and particularly effectively in the smallest space; in the arrangement shown there are in particular the largest possible radii of curvature and thus a low flow resistance in the interior of the oscillating tube, and on the other hand a minimal space requirement, it being possible for the arrangement to take place at the most convenient point for the process of continuous heating.
  • the course of the vibrating tube 24, designated by A and B, the axes of the air cylinder 10 and the exhaust gas cylinder 26 arranged vertically in the boiler can be described as follows: starting from the combustion chamber 23, which is somewhat eccentric to the axis above the air cylinder 10 A is arranged, the vibrating tube 24 initially runs towards the wall of the boiler 1 in such a way that it ends tangentially in an arc around the axis B running as close as possible to the wall of the boiler 1, approximately at point C. The vibrating tube 24 runs from C. then, following this circle around B for a little more than a semicircle, to point D.
  • Connections 20 ', 5, 22', 32 for gas, water, electricity and exhaust gas are arranged on the right-hand side of the device box 3 (in FIG. 2).
  • the lid 35, according to FIG. 3a, the oscillating fire immersion heater arrangement 9 according to FIG. 3b, the boiler 1 according to FIG. 3c and the device box 3 according to FIG. 3d each separately assembled and provided.
  • the oscillating fire immersion heater assembly 9 also includes an instrument panel 44 fastened to the cover 7 by means of supports 43, which in the assembled state (cf. also FIG. 1) through an opening 42 protrudes through the cover 35.
  • the advantage of the aggregate division shown is that the oscillating fire immersion heater arrangement 9 according to FIG.
  • the oscillating fire immersion heater assembly 9 can now, as shown in FIG. 3f, be inserted into the boiler 1, which, as shown in FIG. 3g, has already been mounted on the equipment box 3 beforehand. Then, as shown in Fig. 34, the lid 35 is put on. The entire arrangement is shown in Fig. 3h. Maintenance is similarly simple; it is only necessary to remove the cover 35 and then to remove the cover 7. It can then be serviced immediately with the entire oscillating fire immersion heater arrangement 9 in an easily accessible manner or even - if repair is necessary - can be replaced. The exchange of individual units is particularly easy in this way.
  • FIG. 4 and 5 show an embodiment with an increase in the heat output to twice the value. This is done in that - with otherwise identical components - two combustion chambers and two oscillating tubes are arranged.
  • the two combustion chambers 123-1 and 123-2 sit above the air cylinder 110, connected to it in the manner shown in FIG. 6, somewhat eccentrically to the axis A. They are arranged relative to one another with a height difference of, for example, 30 mm in such a way that the vibrating tubes 124-1 and 124-2 emerging from them can be arranged directly above one another at this short distance, with essentially the same shape. They are connected to one another at their respective ends 125-1 and 125-2 in terms of vibrations with the aid of a coupling piece 146.
  • This coupling piece serves to couple the vibrations in the two combustion chamber / vibrating tube systems in such a way that the vibrations each have a phase shift of 180 ° with respect to one another. This ensures the stability of the vibrations of both vibration systems in push-pull.
  • the coupling piece 146 is used for mounting in the exhaust gas cylinder 126. If the cross sections for the intake air have been chosen to be sufficiently large in the exemplary embodiment with only one vibration system, the simple measure of mounting two vibration systems one above the other with only a little more construction cavity of the entire device twice the performance can be achieved. As can be seen from Fig.
  • the cross section of the boiler 1, in deviation from the shape shown in FIG. 2 or FIG. 5, in which it encloses the cylinders standing vertically next to one another, namely the air cylinder 10 and the exhaust gas cylinder 26, is also round can be. Then the capacity of the boiler increases. The round shape is more favorable for strength. Otherwise, the arrangement - with appropriate adaptation of the cover 7 - can remain the same.
  • the air cylinder 10 and the exhaust cylinder 28 are formed in two parts.
