Abstract

Concentric channels for supplying additional air and exhausting the burnt gases, in particular for a heat source (105, 106) running on fuel and provided with a fan, in the form of a connection box (112) consisting of two cylinders and provided on its casing (120), on the side of the heat source (105, 106), with two concentric openings (128/131) for the supply of additional air / the evacuation of the burnt gases and, below, a fresh air intake opening (114) orientable relative to the previous opening, an exhaust pipe (123) of the burnt gases passing through the housing axially from one end to the other to be connected to the discharge pipe (128).

Description

The present invention relates to a branch system

  ment for at least two heaters installed in two different floors, especially for appliances

  with fans, each of which is fitted with a

  fresh air supply line and exhaust pipe

  cuation of burnt gases, the latter opening into a collector outside the room where the appliance is installed

of heating.

  For the connection of several heating devices

  fage, in most cases plans have been made so far

  chimneys inside the building, surrounded by a ma-

  çonnerie, where the evacuation pipes are connected.

  The necessary fresh air was taken in this case most often

  in the installation room, through a suitable opening

  prayed. The disadvantage of such connections is that an exhaust pipe connected to a chimney can have an uncontrollable leak of burnt gases in the

  room where the relevant heater is installed.

  In addition, heaters cannot be installed.

  talled only if there are chimneys where they can be connected

  strung. The invention therefore aims to avoid these drawbacks

  by proposing a system allowing the installation of

  heating reils even if there is no chimney for their connection, and avoiding any risk of leakage of burnt gases.

  This object is achieved according to the invention by the fact that each

- 2 -

  that the flue gas exhaust pipe is surrounded con-

  centrally via a fresh air supply line,

  the exhaust pipes of several heating appliances

  fage installed in different floors opening into

  a discharge pipe disposed substantially vertically-

  the outside of the building, and the supply lines

  fresh air from the various heating appliances

  age communicating with the outside through wall crossings.

  Since the flue gas exhaust pipe

  the strips are housed in the fresh air supply pipe, burnt gases escaping from the first are returned by the last to the heater where they will be

then evacuated again.

  Because the drainage pipes are connected to a drainage pipe, this has the advantage that

  the latter can be quickly and easily

  without affecting the exterior of the building much since it

  largely resembles a downspout.

  The exhaust pipe can be opened at both ends, which allows a continuous circulation of fresh air so that the heater, on the air supply side, is never exposed to dynamic pressures from the

is windy.

  An improvement of the invention consists in that it is provided that the wall crossings o are connected the

  fresh air supply lines open directly-

  on the outside and have a perforated cover.

  In this way, the supply of fresh air is felt

  so much simplified, any variation in the conditions of

  flow into the room where the heating appliance is installed

  fage being avoided. The perforated cover largely avoids the repercussions of dynamic pressure due to the wind on

  the air supply to the heater.

  Another improvement is given by what it is

  provided that the connection between the wall crossings and the con-

  the fresh air supply duct is made by a

-3-

  nalisation located on the inside of the building wall

is lying.

  This embodiment of the connection system also avoids

  if any impact of wind pressure on the power supply

  tation of fresh air from the various heaters,

  especially if the pipeline is open at its two ends

moths.

  To simplify the piping, it can also be pre-

  seen, according to another improvement of the invention, that

  the fresh air supply lines are connected di-

  directly to the wall crossings which they pierce and are connected, if necessary, to a pipe arranged at

outside the building.

  In this case, the flue gas exhaust pipe can be placed concentrically in the wall passage so that no separate passages are required for the

  drainage and supply lines.

  To facilitate the flow of burnt gases, the hose

  can be wrapped in an insulating layer.

  The temperature of the burnt gases is thus largely maintained during the rise of the gases, which ensures an effective vertical thrust. In addition, this allows the discharge pipe to be provided with a relatively small diameter,

  the relatively large vertical thrust ensuring the

  fairly large volume across a given section

born.

  According to another improvement, the evacua-

  tion is housed in a pipeline connecting the crossings

  wall to which the supply lines are connected

tion in fresh air.

  Another improvement of the invention consists in

  what additional air supply routes are planned

  concentric flue gas extraction and evacuation, no-

  especially for a heat source operating on a

  bustible and fitted with a fan, in the form of a connection box characterized by the fact that it consists of 4- - two cylinders and provided on its casing, on the heat source side, with two concentric openings for

  additional air supply / exhaust gas

  strips and, below, a fresh air intake opening

  orientable with respect to the previous opening, a ca-

  nalisation of evacuation of burnt gases passing through the box

  axially end to end to be connected to the

evacuation pipe.

  It is thus possible to carry out a feeding

  in additional air and an exhaust of burnt gases per-

  also putting the connection of devices with a

  tilator to an exhaust pipe, and for which it is also possible to design the air supply

  additional in a very universal way.

  According to another improvement, there is provided a

  seal separating the air supply opening

  nel and the flue gas discharge opening, on the one hand, from the fresh air intake opening on the other, so that the connection box is composed of

  two parts plugged into each other and capable of turning

  ner one opposite the other, the seal being provided with pre-

ference of a fixing collar.

  This results in a very simple construction of the housing.

of connection.

  Hereinafter, the invention is described in more detail with the figures of the drawing in support, which represent: FIG. 1, diagrammatically the connection system for heating appliances, FIG. 2 to 6, different connection variants for heaters, Fig. 7 and 8, perforated covers for fresh air intake openings, Fig. 9, a sectional dwelling house, FIG. 10, the universal connection possibilities of the connection box,

  Fig. 11, the branch box in section.

  As follows from FIG. 1, the heating appliances

  fage 1 installed in two different floors of the building

  2, are connected by concentric pipes 3, 4 to the ex-

  or a flue gas exhaust pipe 5 o

  open the exhaust pipes 4 coming from the interior

  laughing. At the top, the discharge pipe 5 is provided with an

  verture 6 by which the burnt gases can escape

outside.

  Fig. 2 shows an embodiment of the connection system according to the invention, where the evacuation pipe 4 passes through a wall crossing 7 before

  lead into the drain pipe 5.

  The fresh air supply line 3 which surrounds

  re concentrically the evacuation pipe 4, opens into a pipe 9 arranged on the inner face of a wall 8 and composed of two parts which can be plugged into one another to open out, through a passage of

  wall 10, in a pipe 11 mounted on the outside face

  wall 8 and which is connected to the outside air

  respectively opened by at least one of its ends.

  The exemplary embodiment according to FIG. 3 differs

  from that of fig. 2 because line 9 opens

  vre directly to the outside via the passage 10 which is closed by a perforated cover 12, the evacuation pipe being provided with an insulating jacket 13.

  In the exemplary embodiment according to FIG. 4, the-

  which looks a lot like the one in fig. 2, the water pipe

  vacuation 5 is housed in the pipe 11 'mounted on the outer face of the wall 8 and which connects the wall crossings 10 which communicate with the pipes

  fresh air 3 installed in the different floors.

  In the exemplary embodiment according to FIG. 5, the-

  which looks a lot like the one in fig. 4, driving

  te of fresh air 3 leads directly into a crossing

  wall 7 'where the burnt gas pipe 4 is also housed.

  In the exemplary embodiment according to FIG. 6, the burnt gas pipe 4 is connected to the discharge pipe by an elbow, the fresh air pipe 3 opening directly into the bushing 7 'which, if necessary, can

  be covered by a perforated cover.

  Such a cover 14 emerges from FIG. 7 and presents

  a central orifice 15 through o passes the burnt gas line

  strips 4. In addition, it has strips 16 which cover

partially slits.

  For the covering of wall crossings where only fresh air pipes 3 pass, or of crossings opening into a pipe 9, provision may be made for

  perforated covers 12 provided with strips 19 overlapping by-

partially slits.

  The house according to fig. 9 includes two

  floors 102 and 103 separated from each other by a ceiling 104.

  Each floor has a 105 circulating water heater

  or a boiler 106 running on gas or oil and

  bearing or a spray burner or a medium burner

  swaddle with fan. Circulating water heaters

  lation and boilers - but just as well

  storage water, stoves and simple instant water heaters

  tanned - used for heat generation and heating

  age of the floor concerned or in combination or alternative-

  with domestic water heating. Appliances 105 and 106 are fireplaces independent of indoor air so that the heat source they form, walking on a fuel, must be connected by pipes

  air and flue gas concentric 107 to the atmosphere

  pectively to a chimney 108. The chimney 108 comprises

  at the lowest point a maintenance box 109, behind

  re a door, from which the evacuation pipe 110 leaves,

  upwards, to arrive at a first branch box

  chement 111 polygonal or consisting of two cylinders and cooperating with the boiler 106. Then the pipe 110 extends to a second connection box 112 disposed above the first identical with the other. Of

* -7-

  there, the pipe 110 continues to the gas outlet 113 which is approximately at height of the roof. The connection box 112 cooperates with the circulating water heater 105. From FIG. 9, it appears that, depending on the number of dwellings in the dwelling house 100, one or more

  105 or 106 heat sources, operating on combustible

  ble, are planned and installed one above the other

  tre and can be connected to a common pipe 108.

  Fresh air reaches heat sources through the

  inlet ports 114 made in the housing envelope

  connection tier 111 or 112. It can be seen that the air intake orifices 114 can be placed in variable positions. To obtain water-repellent insulation, the pipe is surrounded by insulation material. The chimney 108 is moreover housed in a masonry or provided at least

an envelope 116.

  Different representations of fig. 10, it remains

  fate that a triangular envelope 117 is used and that the water heater 105 is disposed opposite this envelope,

  the wall 118 of the house being pierced by the pipe 107.

  As seen in fig. 10, the pipe 107 concentrically contains the exhaust pipe for the burnt gases arranged inside and thus surrounded by an annular space which serves as a supply line for fresh air

  for heat source 105. We can also see that the

  intake of fresh air 114 can be oriented on one side of the triangle 117 or on the other, that is to say the inlet 114 '. The

  drawing at the top right of fig. 10 shows an envelope

  prismatic pe 117 thus allowing three different positions

  for the entry of fresh air. Drawing below in fig. 10, it appears that the concentric lines of additional air supply and exhaust gas

  burnt 107 can also be arranged at an angle.

  The connection box 112 comes out in more detail

  of fig. 11. It is designed as a double cylinder which

  takes an envelope 120 with two covers 121 and 122 8 - at its ends. These covers are pierced by a tube

  interior 123 which extends from one of the covers to

  than the other and exceeds them by tubing 124. It en-

  This results in a space 125 inside the tube 123 and an es-

  annular space 126 between the envelope and the tube. The interior space 125 functions as a pipe for evacuating the burnt gases, the pipes 124 being connected to the elements of the pipe 110 (see FIG. 9). The lower tube 124 is either closed by a cover 127 or connected by a section

of pipe 110 to box 109.

  Near the upper cover 122, a hose

  evacuation 128 is connected perpendicularly to the tube 123.

  It crosses the annular space 126 and pierces with an orifice.

  this 129 envelopes 120. This orifice 129 has a cross section

  blow larger than is necessary for the passage of the pipe 128 from which results an annular space 130 which is used for the arrival of fresh air. It is surrounded by a tube 131 welded to the orifice 129 of the envelope 120. The pipe 128 and the tube 131 fit together with the pipe 107

  leading to heat source 105 or 106. Nearby

  tee of the lower cover 121 is provided another orifice corresponding, in terms of its diameter, to the orifice 129 and also provided with a pipe 131 which is similar to the pipe 131 above. This tubing 131 serves as an inlet

  of air 114. Between the two orifices 129, the void space

  re 126 and the inner tube 123 are cut in half, the separation joint being marked with 132. At this joint produced by overlapping, the upper part 133

  of the connection box 112 can be rotated

  port at the bottom 134. It is thus possible to

  vary the position of the pipes 131 and 128 in the

  upper tie with respect to the fresh air inlet 114. A collar 135 can be applied to the separation joint which ensures the respective position of the two parts 133 and

  134. The elements of the inner tube of the branch housing

  are pluggable, without fixing in a determined position -9-. For added security, the lower part 134 of the

  connection box can be fitted at the level of the

  circle 121, of a condensate drain hole 136. The main part of the connection box therefore consists

  in that by grouping all the evacuation pipes

  tion 128 of all heat sources installed in

  a building, fresh air inlets 114 may be available

  asked individually so as to assign to each

  similarly its own air inlet 114 whose position can, moreover, vary. Although connected to the same pipeline

  the various burnt gas outlets may

  can be placed in variable positions, as well

  relative to the position of the pipe 108 than to that

  the different air inlets 114. This results in a

  universal connection possibility.
