Definitions

  • the invention relates to an additional device for stoves, which are heated with solid fuels and operated without external fresh air.
  • FR-A1-2 556 820 describes such an accessory.
  • a stove with a cylindrical combustion chamber which is designed as a hot air oven.
  • the combustion chamber is formed from bent steel tubes, the tube surface partially within the combustion chamber lays. Cold air is sucked in through the pipes, which flows from the bottom to the top, is heated and flows off at the upper end of the pipes as warm air. Due to the continuous circulation process, a rapid and uniform heating of the room air should be achieved.
  • a heat exchanger is known for a stove ( DE 81 05 368 U ), wherein in the firebox of the stove, a boiler with an air inlet opening and an air outlet opening, which are located outside of the firebox is arranged. Cold air is flowing Through the inlet openings in the boiler, is heated in this and returned as heated air through the outlet opening to the environment.
  • the invention has for its object to provide an additional device for stoves, which leads to a significant improvement in indoor climate, allows a good and uniform room air circulation, provides a sufficient amount of combustion air and can be installed at low cost.
  • the flue gas outlet pipe of the stove is surrounded by an air-conducting jacket pipe with two offset by at least 90 ° arranged connecting pieces.
  • the one connecting piece communicates with a first channel for supplying fresh air, in which a shut-off element is integrated.
  • a third channel for the intake of room air is involved, which is equipped with a shut-off.
  • the other spigot is connected to an upwardly directed second duct for the delivery of heated air, which is equipped with a shut-off device.
  • the third channel for intake of room air is preferably connected to branch channels, which terminate at different points of the room, in the area of the wall bounding the room, near the floor.
  • the second, hot air leading channel is led to the area of the ceiling.
  • the second channel is closed by means of a shut-off and the channels for the supply of room air and fresh air are open.
  • the obturator in the second channel assumes an open position, the room air supply is interrupted and the channel for the fresh air supply is open.
  • the channels for the supply of fresh air and room air are open or optionally switchable.
  • the auxiliary device can be coupled to an automatic control device, which controls the opening and closing of the shut-off devices by means of actuators based on measured values for the oxygen content in the room air, the flue gas temperature and the room air temperature.
  • the proposed accessory requires no additional electrical energy, is maintenance-free and easy to operate. It supplies the room and the heating source with the required combustion air through the independent intake of fresh air. In the heated Room is created a pleasant room climate, since it is sufficiently supplied with fresh air. In the room a good mixing of the room air is guaranteed due to the prevailing thermals.
  • a solid fuel heated stove 7 ( Fig. 1 ).
  • the room 1 is bounded by side walls 3, 4 and a ceiling 5.
  • the stove 7 is placed in the immediate vicinity of the chimney 6 ( Fig. 2 ).
  • the flue gas removal pipe 8 of the stove 7 is integrated into the associated chimney flue.
  • a jacket tube 9 is arranged concentrically around the flue-gas removal tube 8, an annular channel 10 being formed between the flue-gas removal tube 8 and the jacket tube 9. The two end faces of the jacket tube 9 surround the flue gas outlet tube 8 airtight.
  • the jacket tube 9 has two connecting pieces 11 and 12, which are arranged offset by 180 °.
  • the upwardly facing connecting piece 11 is connected to a riser 13 (second channel).
  • the riser 13 extends into the ceiling area and has at its upper end an air outlet opening 13a, flows through the heated hot air.
  • a shut-off device 13b is incorporated to prevent the escape of not yet sufficiently heated air during the heating of the stove 7.
  • Stelgrohr 13 may additionally be connected to an air distribution line 14 which is circumferentially guided in the region of the ceiling 5, along the side walls 3, 4 and partially has air outlet openings 14a.
  • a pipe or channel 15 is connected, which is connected to a line 16 (third channel) for supplying or suction of room air and a line 17 (first channel) for supplying fresh air ,
  • a respective obturator 16a and 17a is arranged so that the pipe or channel 15 either fresh air or room air can be supplied.
  • the two lines 16 and 17 are preferably laid below the floor 2.
  • the conduit 16 for supplying room air is guided along the side walls 3, 4 and has a plurality of vertically arranged intake 16b, which are guided in the sidewall near the floor 2 and end immediately above the floor 2.
  • the conduit 17 for supplying fresh air is connected via an opening in one of the outer walls of the building with the outside air.
  • the obturator 13b of the riser 13 is closed.
  • the shut-off elements 16a and 17a of the lines 16 and 17 for the supply of room air and fresh air remain open. Due to the discharged through the pipe 8 in the chimney 6 hot flue gases in the annular channel 10 and riser 13 located air is heated. After completion of the Anhelzphase, the discharged into the chimney flue gas has reached an operating temperature of about 200 to 300 ° C, the obturator 13a is opened and closed the obturator 16 for supplying room air.
  • the heated air in the riser flows near the ceiling and fresh air is sucked in via the line 17, which is heated during the flow around the hot flue gas discharge pipe 8 in the annular channel 10 to a temperature up to about 40 ° C.
  • This warm air flows in the ceiling area via the riser pipe 13 or the air outlet openings 14a of the air distribution device 14 at ceiling height.
  • the natural flow process prevents the formation of heat build-up in the ceiling area.
  • the warm fresh air flows along the side walls 3, 4 of the room and ensures a uniform room air circulation.
  • the room air is thus supplied with sufficiently heated fresh air, so that the oxygen content of the room air is relatively high and takes place by the combustion process taking place in the stove oxygen deprivation to no oxygen deficiency in the indoor air.
  • the obturator 16a of the line 16 can then be opened, so that combined fresh air and room air are sucked in and heated.
  • the accumulated in the floor near, still relatively cool air flows through the intake manifold 16b and is heated together with fresh air in the annular channel 10 and passes as heated air in the ceiling area of the room. If old shut-off elements 13b, 16a and 17a are completely or at least partially open, then a relatively stable flow level arises in the room.
  • the obturator 17a for the supply of fresh air can be closed, but it should be noted that the room should be supplied with fresh air in other ways.
  • the proposed additional device works automatically without external energy and ensures a pleasant indoor climate. It can be cheaply manufactured and assembled. If necessary, the opening and closing movements of the shut-off can be done by means of electric actuators, which are integrated into an automatic control system, via which also room temperature and / or oxygen content in the room can be monitored and controlled.
