Definitions

  • the present invention relates to a device for thermostatic regulation of the temperature of an apparatus for producing hot water associated with an open indoor fireplace.
  • Hot water production devices connected to a central heating system in open fireplaces are already known.
  • the known devices for producing hot water mention may be made of those described in documents FR-A-2 321 092 and FR-A-2 333 207. These devices all consist of a box filled with water which is placed under and behind the hearth and in which the water is heated by the heat of the hearth.
  • the heat output of a heat exchanger is a function of several parameters, such as quantity and quality of wood used, chimney draft, ventilation rate at the hearth , and way of driving the fire.
  • the chimneys with partitions, as described above make it possible to improve the draft and the ventilation rate, the management of the fire continues to require constant surveillance on the part of the users.
  • An object of the present invention is to provide a water heat exchanger device for ensuring a more complete recovery of the calorific value of the fuel.
  • Another object of the invention consists in providing a device making it possible to obtain an improvement in the heating of the water and a constant temperature at the outlet of hot water from the heat exchanger.
  • the temperature-sensitive means are elements which expand and which are mounted in a cavity of the box, the free end of said elements being connected to the plate by means of a mechanical lever system.
  • the open hearth in FIG. 1 conventionally comprises a hearth plate 1 on which there are ignited logs 2, a counter-fire 3, legs 4, a lintel 5, a hood 6 and a smoke duct 7.
  • a partition 8 In front of the counter-fire 3, a partition 8 has been mounted which occupies the entire width of the chimney between the jambs 4.
  • the distance between the partition 8 and the bottom of the chimney can be 15 to 20 cm.
  • the compartment thus delimited between the partition 8 and the bottom of the chimney communicates in its upper part with the smoke duct 7.
  • an opening 9 is provided which descends to the hearth plate 1.
  • the opening 9 is, preferably if the chimney is symmetrical, also symmetrical between the legs 4 and its width may be less than the distance between the legs.
  • the hearth plate 1 is the upper face of the base of a box 14 with an L-shaped section.
  • the front face of the rising part of the box, corresponding to the leg of the L constitutes the counter plate. fire 3.
  • the box 14 is filled with water and comprises an inlet pipe 15 for cold water, provided at the base of 14, and an outlet pipe 16 for hot water, provided in the upper part of the leg of the box.
  • the pipes 15 and 16 are connected to a set of central heating radiators or to a sanitary water tank, or to devices of this kind, not shown.
  • the circulation of water in the installation can be forced by a conventional pump or accelerator, not shown.
  • the upper plate 17 of the box 14, at the top of the leg, is provided with a cavity 18 descending inside the box.
  • the cavity 18 is preferably constituted by a tube closed at its lower end and open upwards. The edges of the opening of the tube 18 are welded to the edges of the hole drilled in the plate 17 for the passage of the tube.
  • three elements 19 are superimposed which have a relatively large coefficient of expansion.
  • the upper element 19 supports the bottom of a rod 20 which is connected to a lever arm 21 by a horizontal axis 22.
  • One end of the lever arm 21 is pivotally mounted around an axis 23 carried by the two legs d 'a bracket 24 which is fixed, by appropriate means, to a wall of the chimney.
  • the elements 19 When the water in the box is cold, the elements 19 are retracted and the axis 22 is at its lowest point, like the axis 25. So the rod 26 and the plate 10 are in the low position.
  • the elements 19 expand, the axis 22 rises as well.
  • axis 25, and plate 10 goes up.
  • the relative distances between the axes 22 and 23, on the one hand, and the axes 25 and 23, on the other hand, are chosen so as to obtain the appropriate amplification coefficient between the expansion of the elements 19 and the plate stroke 10.
  • the vertical front or counter-fire face 3 of the box has ribs 27 which improve the heat exchange of the smoke gases and flames with the box.
  • the base of the ribs 27 is cut at 45 °. Tubes open at the base and at the top of the vertical part of the box can be provided to allow flames and hot gases to pass and thus improve the heat exchange surface.
  • deflectors can also be provided to improve heat exchange.
  • a second simple prismatic box 28 which serves as an air heat exchanger.
  • the box 28 comprises an air inlet pipe or inlet port 29 and an air outlet pipe or outlet port 30.
  • the pipe 29 is preferably connected to the outside, by a suitable sheath , to get fresh air.
  • Tubing 30 opens into the room where the chimney is installed.
  • the temperature of the water in the exchanger will rise quickly. From 45 ° and gradually up to 90 °, the expansion of the thermostatic elements 19 will come into action, exerting a push on the lever arm 21, which will raise the movable plate 10, which will reach its highest point when the temperature water will be 90 °.
  • the combustion will decrease in intensity and the fire will take on an appearance similar to that of a traditional chimney operated by natural depression.
  • a chimney has been shown in which, in front of the partition 8, there is a passage 31 towards the smoke duct 7. This passage can be obstructed by a flap 32, the position of which can be controlled by a chain 33.
  • the shutter 32 is closed and the chimney operates as indicated above.
  • the plate 10 is lowered completely to the hearth plate 1 and the flap 32 is opened.
  • One can then make a fire as in a conventional chimney.
