Definitions

  • the invention relates to an improvement to 1 direct smoke evacuation in closed fireplaces with front access door and other heating assemblies with loading door and liquid fuel.
  • It relates more particularly to an assembly having an adjustable closure member with an opening subject to that of the access door opening onto a nozzle projecting inwards.
  • the open fireplaces offer an undeniable pleasure by the direct radiated heat and the feeling of well-being that comes from it, linked to affective and sentimental impressions. We like to find them in living rooms, even in new construction where they symbolize the warmth of the house.
  • tubular log supports forming a cradle, through which blown air is heated which comes into contact with the tubes and directly carries calories through the room, tubes traversed, if necessary, by a heat transfer fluid providing the central heating installation with the additional calories recovered.
  • the air recovery is also carried out on side plates placed slightly projecting in the hearth so as to form between the walls of the chimney and said plates a circulation corridor where the air heats up and is evacuated through the room.
  • the improved embodiments have double walls between which a first air flow circulates.
  • the second air flow passes through the volume delimited by the exterior walls and the chimney wall.
  • the smoke is imposed a greater path by shifting the outlet orifice of the fireplace towards the access door. The smoke then leaves after passing through this baffle towards the outlet nozzle located at the opposite end.
  • the fumes lose useful calories on this additional path which previously only contributed to heating the flue. They are recovered by a transverse air flow between the lining of the chimney and the walls of the hearth.
  • the action on the handle opens the tilting auxiliary valve while the main valve controlling the speed of the fire is manually adjusted.
  • This mechanism is removable and controlled by the handle. It therefore has no automatic operation.
  • HIGHLEY US Patent No. 2,443,910 relates to a mechanism for controlling a movable deflection plate in a closed hearth.
  • a pendulum is associated with a push rod in contact with the door.
  • the push rod controls the opening of two half-shells when the door opens to establish a direct path for the fumes.
  • This complex mechanism which must convert a pushing movement into a horizontal release movement, does not offer any sufficient guarantee of operation at the temperatures of the fireplace and the fumes.
  • the US patent SCHRADER US n ° 4313 418 presents a device with adjustable arm fixed on the door whose movements control the opening or the progressive closing of the lateral air intake respectively during the closing and the opening of the door. This small opening makes it possible to adjust the speed of the fire but cannot constitute a safety device when the door is opened.
  • the present invention proceeds from a different inventive idea which consists in making the opening of the discharge valve fully automatic when the access door to the closed hearth is opened.
  • control lever articulated on the ccés door in the vicinity of the hinge is not ns the axis of the translational movement making it difficult.
  • the door opening remains limited to an angular value close to 90 °. This limitation hinders in certain circumstances and configurations the loading and use in open fire.
  • the object of the invention is to remedy these drawbacks and to further increase the efficiency of this type of heating with recovery.
  • the improvement according to the invention relates to a direct smoke evacuation assembly for a closed fireplace hearth with a front access door characterized by a shutter controlled by the movements of the access door in the form of a flap. pivoting plane with off-center axis, controlled in tilting by a sliding push rod ensuring the kinematic connection between the door and an inclined control lug for the conjugate tilting in opening or closing of the pivoting plane with the movements in opening or closing of the door.
  • the improvement according to the invention relates to the shutter assembly, its control, the outlet from the hearth and the departure via the exhaust duct.
  • a front access door 2 closes the front face. It presents a transparent panoramic surface 3 offering the observer the total vision of the home.
  • This set includes a convection recovery circuit along the double walls.
  • the air thus heated exits in the upper front part through two vents such as 4.
  • a direct exhaust of the fumes 5 is provided in the upper part by a pivoting valve 6 controlled in opening and closing directly by the movements of the access door 2.
  • This valve communicates with a nozzle. outlet 7 with low entry and fitting for the connection of the heating assembly with the duct 8 for discharging the fumes.
  • the communication shutter assembly consists of the following parts.
  • a support frame 9 attached to the body of the heating assembly maintains the assembly.
  • This frame includes a direct discharge opening 10 closed by the valve 6 when the access door is closed and a recovery opening 11 forming a passage for the baffle 12 used for increasing the smoke path in the upper part (path in dotted lines), and therefore the recovery of all possible calories.
  • the valve 6 proper consists of the opening 10, for example rectangular, covered with a peripheral seal 13, of a pivoting flap 14 around an off-center longitudinal axis 15 carried at the ends by the support frame 9.
  • the flap 14 has at its axis an inclined control plane 16, of the lug type, forming a stop for a push rod 17 with rounded ends 18 sliding in a sleeve 19 attached to the support frame 9.
  • This rod transmits the return movement when opening the valve 6 to the access door 2 with which it is in contact via an upper transverse plate 20 beyond the edge profile 21.
  • the pivot axis 15 of flap 14 is slightly offset towards the longitudinal edge on the door side. Therefore, it will present a restoring force in opening resulting from the imbalance of the masses thus formed.
  • This opening reminder constitutes positive security and guarantees the rod 17 a translational movement even by slight friction.
  • the pivoting valve 6 is used in combination with an outlet nozzle 7 with low entry and fitting.
  • the body of this nozzle projects widely inside the upper part of the heating assembly by a maximum distance limited by the short side of the flap and the need for a correct draft in the closed position of the valve.
  • the depression of the nozzle in the body of the heating assembly is such that the protrusion of the upper face remains low.
  • fitting and the low projection in the upper part greatly contribute to the ease and convenience of assembly, in particular at the level of the connection with the exhaust duct 8.
