Definitions

  • the invention in broad terms relates to an assembly of a building with a vertical wall and an inlet/outlet pipe system with an inlet/outlet mouthpiece of the horizontal type.
  • the pipe system extends through the vertical wall, and the mouthpiece lies on the outside of the wall.
  • a combustion plant such as a heating plant for heating a building and/or supplying hot water to a building.
  • Inlet/outlet pipe systems for such assemblies are known and can be divided into pipe systems of the vertical type and pipe systems of the horizontal type.
  • the pipe system leaves the building in the vertical direction through a roof of the building
  • the pipe system leaves the building in the horizontal direction through a generally substantially vertically extending external wall of the building.
  • the inlet/outlet pipe system inside the building can be routed vertically and/or horizontally and/or obliquely, depending on the place where the combustion plant is set up.
  • the invention relates to an assembly comprising:
  • the flue gases discharged through the pipe system contain a large amount of moisture which, particularly in the case of high-efficiency boilers, on leaving the pipe system very readily settles as condensate as a result of the low temperature of the flue gases and as a result of the low ambient temperature outside the building. If nothing is done about discharge of this condensate, the following will occur:
  • the object of the present invention is to provide an assembly according to the preamble of Claim 1, in which the condensate droplets are prevented from coming out of the outlet pipe part to the outside.
  • the outflow part is in the form of a diffuser, which reduces the velocity of flue gases flowing through the outflow part or, put differently and in more general terms, in that the outflow part comprises means for reducing flow velocity.
  • the outflow of condensate droplets from the outlet pipe part to the outside is caused - or at least partially caused - by the fact that they are entrained by the flue gases along the bottom of the outlet pipe part.
  • the flue gases here entrain the condensate droplets up along the slope. This phenomenon occurs particularly in the case of heavily loaded combustion boilers.
  • the ability of the flue gases to entrain condensate droplets is reduced by reducing the velocity of the flue gases in the outflow part.
  • the bottom or underside of the outlet pipe part, and thus also that of the diffuser forming part of it, according to the invention extends at a slope, so that this enables the condensate droplets to flow more easily down along the slope and back into the building.
  • the outflow part diverges in the longitudinal direction of the outlet pipe part.
  • a diffuser is thus achieved in a simple manner. It is furthermore advantageous here if the divergence of the diverging outflow part extends substantially along a continuous line. This prevents abrupt transitions along the internal surface of the outlet pipe and prevents the flow behaviour of the flue gases from being influenced as a result of such abrupt transitions.
  • the divergence is such that over an axial length of 5 to 10 cm the internal diameter of the outflow part increases by at least 15%.
  • the divergence is such that over an axial length of 5 - 10 cm the internal diameter of the outflow part increases by a maximum of 50%.
  • the free end of the outflow part is provided with a cap extending transversely to the longitudinal direction of the outflow part.
  • a cap prevents a wind blowing against the external wall from being able to blow directly into the outlet pipe part, which is undesirable with the reduced flow velocity in the outflow part achieved according to the invention.
  • the side of the cap facing the inside of the outflow part is in the form of a conical surface with the tip of the conical surface facing the inside of the outflow part. The conical surface on the cap then guides the flue gases outside.
  • the outflow part has an underside, an upper side, and sides extending between the underside and upper side, and the underside and upper side of the outflow part are closed, and the sides are provided with windows for allowing flue gases to flow out laterally.
  • the closed underside of the outflow part ensures that condensate droplets can be conveyed along said outflow part back into the building.
  • the closed upper side of the outflow part at least partially prevents condensation and prevents an air flow in the downward direction - for example, a wind flow guided vertically downwards along the external wall - from striking against the closed underside of the outflow part and being.guided by said closed underside into the outlet pipe part, which would disrupt the discharge of flue gases.
  • Providing both sides with windows means that an air flow directed along the external wall can blow into the outflow part from one side, but it will produce a draught on the other side, so that adequate ejection of flue gases remains ensured.
  • the cap is connected to the outflow part by a film hinge and also a snap connection, and if the cap is manufactured by injection moulding from plastic in one piece with the outflow part, in particular with the inlet/outlet mouthpiece.
  • the cap can then lie in an extended position relative to the outlet pipe part which is suitable for releasing from the injection mould, or it can lie in another position which is suitable for releasing from the injection mould, while after releasing from the mould the cap can be fixed simply by swinging about its hinge and snapping into the correct position.
  • the outflow end of the pipe part comprises an inflow aperture which opens in the longitudinal direction of said inlet pipe part.
  • Such an inflow aperture of the inlet pipe part opening in the horizontal direction is susceptible to air blowing in, which ensures a good feed to the combustion plant when the wind is blowing against the external wall.
  • this has the advantage that the wind blowing against the external wall also assists the discharge of flue gases, since an inward - or a greater inward - thrust in the air supply towards the combustion plant results in a greater outward thrust in the flue gas discharge away from the combustion plant.
  • the bottom of the part of the outlet pipe part projecting beyond the inlet pipe part extends at a steeper angle relative to the horizontal than the part of the outlet pipe part situated inside the inlet pipe part.
  • the degree of slope is thus increased in the outflow part.
  • the steeper angle is possible in particular by the fact that the outflow part of the outlet pipe part is situated outside the inlet pipe part.
  • the invention relates to an inlet/outlet mouthpiece which is suitable for, in particular is intended for, the assembly according to the invention.
  • an inlet/outlet mouthpiece is characterized in particular by an inlet/outlet mouthpiece comprising:
  • the invention relates to a method for manufacturing an inlet and/or outlet mouthpiece, in particular, but not exclusively, an inlet/outlet mouthpiece for an assembly according to the invention, in which a pipe part and cap for overlapping with a free end of said pipe part are formed by injection moulding from plastic in one piece with a connection to each other by a film hinge; and in which it is only after being released from the injection mould that the cap is taken into the position overlapping the free end of the pipe part by swinging the cap about the film hinge.
  • FIG 1 shows very diagrammatically an assembly 9 according to the invention.
  • Said assembly comprises a building with an external wall 3 and an inlet/outlet pipe system 2 with an inlet/outlet mouthpiece 1 (hereinafter called mouthpiece).
  • the inlet/outlet pipe system supplies combustion air from outside the building to a combustion plant 4 set up inside the building and discharges flue gases coming from the combustion plant 4 to the outside of the building.
  • the inlet/outlet pipe system can also comprise channels which are routed partially or largely outside each other, the system is shown in Figure 1 with an outlet channel 6 situated inside the inlet channel 5. The air is then supplied through passage 7, and the flue gases are then discharged through passage 8.
  • the mouthpiece 1 is provided substantially on the outside of the external wall 3 on the free end 10 of inlet channel 5 and outlet channel 6 facing away from the combustion plant 4.
  • the connection of the mouthpiece 1 to inlet channel 5 and outlet channel 6 can lie in the external wall, but said connection can also lie fully on the inside or outside of the external wall.
  • Figure 1 furthermore shows by means of reference numerals that the mouthpiece 1 comprises an inlet pipe part 11 and an outlet pipe part 12. Said mouthpiece 1 will be discussed further below with reference to Figures 2, 3 and 4 .
  • the mouthpiece 1 comprises an inlet pipe part 11 with - on the right in Figures 2 and 3 - an inflow end 13 by means of which air can flow by way of inflow aperture 28 ( Figure 4 ) into the inlet pipe part 11, as indicated by arrow 14.
  • the inlet pipe part can be inserted by the left end in Figures 2 and 3 into the free end of inlet channel 5 ( Figure 1 ).
  • the annular projection 31 here provides a stop which prevents the inlet pipe part from being inserted too far into the inlet channel 5.
  • the mouthpiece 1 furthermore comprises an outlet pipe part 12 whose end which is on the left in Figures 2 and 3 can be connected to the outlet channel 6 ( Figure 1 ).
  • the outlet pipe part 12 has a horizontal annular accommodation slot 32, in which the free end of the outlet channel 6 can be accommodated, an annular sealing projection 33 for sealing on the outside of the outlet channel 6, and a plurality of clamping lips 34 distributed all the way round for clamping action upon the outside of the outlet channel 6.
  • the outlet pipe part 12 extends through the inlet pipe part 11 and projects (on the right-hand side in Figures 2 and 3 ) from the inlet pipe part 11 with an outflow part 15 situated outside said inlet pipe part 11.
  • outflow part 15 of the outlet pipe part 12 is clearly positioned obliquely relative to the inlet pipe part 11
  • inlet pipe part 11 and outlet pipe part 12 are routed substantially parallel relative to each other and relative to the horizontal.
  • the bottom/underside 20 of the part of the outlet pipe part 12 situated in the inlet pipe part 11 is preferably routed at a slight slope, such as approximately 1° or more, in order to be able to return condensate to the outlet channel 6, which likewise is preferably routed at a slight slope.
  • the bottom/underside 17 of the outflow part 15 extends at a slope of 3° to 4° or more. If the slope of bottom/underside 20 in the inlet pipe part 11 is already sufficiently large, bottom part 17 and bottom part 20 can be routed at the same slope.
  • the outflow part 15 is in the form of a diffuser 21.
  • this is, as it were, achieved by starting from a first part of the outlet pipe part 12 with constant diameter situated in the inlet pipe part 11, say 60 mm, which is routed horizontally or at a slight slope, such as approximately 1°, relative to the horizontal.
  • a second part of the outlet pipe part 12 is fitted, as it were, on said first part (on the right in Figures 2 and 3 ).
  • Said second part consists, as it were, of a pipe part whose internal diameter B diverges from a diameter of 60 mm to a diameter of 80 mm over an axial length A of approximately 10 cm.
  • This second part is fitted at a relatively larger slope ⁇ of approximately 3 - 4° (a slope of approximately 1° would, however, be possible) than the first part.
  • the first part and second part are preferably manufactured as a single-part injection-moulded product, instead of each being a separate part.
  • the diffuser can also be designed in a different way, but it is important for the underside/bottom of the diffuser to extend at a slope in order to drain back into the inlet/outlet pipe system 2.
  • a cap 22 is provided on the end of the outlet pipe part 12 which is shown on the left in Figures 2 and 3 . As can be seen in Figure 4 , said cap 22 does not shield the outlet pipe part 12 completely on the sides 19. If desired, the cap 22 may be made broader, in order to shield the end of the outlet pipe part 12 fully from the wind blowing against the outside wall.
  • the inwardly facing surface 23 of said cap is of a conical design with the tip 24 of the cone pointing into the outlet pipe part 12. Flue gases arriving at the cap are guided out better in this way.
  • the outflow part 15 on each side 19 is provided with windows 25 (in this case 3 windows per side, but there can also be more or fewer).
  • the underside/bottom 17 of the outflow part 15 is of a closed design here, in order to return condensate.
  • the upper side 18 of the outflow part 15 is of a closed design here, in order to prevent wind from blowing downwards on the bottom 17 of the outflow part 15 and in this way being able to blow flue gases back into the system.
  • the bottom 17 of the outflow part is, as it were, trough-shaped owing to the fact that the sides go up slightly as a result of the round shape.
  • Said trough shape can, if desired, be reinforced by providing vertical ribs or walls in the longitudinal direction L of the mouthpiece.
  • the advantage of the trough shape is that wind from the side, i.e. perpendicular to the plane of drawing according to Figure 2 , has little or no grip on condensate flowing back through the 'trough'. This ensures that condensate is not blown laterally out of the mouthpiece.
  • the conically 23 designed cap 22, the windows 25 in the sides 19 of the outflow part 15, the divergence of the outflow part 15 and the inflow aperture 28 opening in the longitudinal direction of the inlet pipe part 11 produce various advantageous effects, particularly in mutual combination, but also individually. These advantageous effects are, inter alia:
  • the improved ejection and feedback of settled condensate which are achieved with the assembly according to the invention are important particularly because in this way in wintry conditions ice formation on the inlet/outlet mouthpiece is prevented and because in this way generally flue gases and condensate are prevented from coming into contact with parts of the inlet system.
  • the latter is advantageous because the inlet systems generally contain parts which are susceptible to corrosion and these parts must be prevented from corroding in order to prevent breakdowns.
  • cap 22 and pipe part 15 in one piece from plastic and in the process connect the cap and the pipe part to each other by means of a film hinge 23.
  • the cap can then assume any desired position relative to the pipe part in the mould during the injection moulding, so that the mould can be made of a releasing design.
  • the cap 22 can then be fixed on the pipe part 15 by means of adhesives or a screw or in some other way after the cap 22 has been swung transversely over the pipe part 15. It is advantageous during the injection moulding to co-mould snap means for a snap connection, as indicated by 27 in Figure 2 .
