Definitions

  • the present patent application for industrial invention relates to a stove with built-in boiler for the production of hot water used for sanitary services and/or radiator heating installations.
  • the major drawback of the stoves of known type consists in the lack of a device able to adjust the flame according to the temperature reached by the water contained in the exchangers, where water temperature of course varies according to the water load absorbed by utilities.
  • Stoves of known type are not provided with automatic devices for flame adjustment and the flame is always on, bringing hot water to maximum temperature values, which may be excessive for the requested use.
  • US 6 029 640 and GB 523 610 disclose stoves with built-in boiler for hot water production with openings that can be internally obstructed by a flap and being controlled by a thermostat.
  • EP 0 205 993 discloses a solid fuel inverted flame boiler for hot water system in which the hot transfer occurs by means of radially disposed member of L-section.
  • GB 830140 discloses a furnace comprising a main chamber and an auxiliary chamber adapted to receive an oil burner insert.
  • the main purpose of this invention is to significantly improve the thermal efficiency of this type of stoves, first of all by eliminating the energy waste that occurs today when combustion remains unaltered when the request for water from utilities has ceased.
  • the stove of the invention has been provided with a device capable of turning the flame on and off according to the temperature reached by hot water. In this way, combustion is interrupted when the set temperature value is reached, and then automatically restored when the water temperature falls below the threshold value.
  • the energy saving resulting from the use of such an adjustment device is not only related to the elimination of thermal waste, being also determined by the capability of setting the hot water temperature as desired by the user.
  • the stove of the invention allows reducing fuel consumption according to external climatic conditions or personal user requirements.
  • the location and direction of exchangers inside the fire-box have been suitably chosen to force combustion products along an ascending travel, thus favouring maximum thermal exchange and at the same time preventing the formation of sooty deposits on thermal exchange surfaces.
  • the stove of the invention comprises a fire-box that is hermetically closed by a front door with shutter.
  • the door When closed, the door comes in contact with a border that borders the mouth of the stove and has a series of through openings, through which external air can enter the fire-box to feed combustion.
  • the air flow through the openings can be interrupted by means of a collapsible intercepting screen located immediately behind the border and capable of assuming two different positions, which correspond to total closing or total opening of the openings.
  • the collapsible intercepting screen can be raised or lowered by means of a lever system actuated by an electric engine controlled by a thermostat and provided with a device that determines inverse rotation at every start.
  • the fire-box has a parallelepiped shape and is provided with walls with a space filled with water; a first bracket projects from the back vertical wall and transversally extends from one side to the other, being interrupted near the front wall, slightly above the mouth of the stove.
  • the first bracket has a space that receives the water coming from below through a first ascending pipe which communicates with the space of the back wall.
  • a second ascending pipe starts above the first bracket and ends in the space of a second projecting bracket, which is fixed inside the front wall and transversally extends from one side to the other, being interrupted near the back wall, slightly above the first bracket.
  • the second bracket communicates with the space on top of the fire-box, where the hot water feed union is located, while the cold water input union for the cold water returning from the radiators is located under the bottom wall of the fire-box.
  • the stove of the invention comprises a metal bearing structure closed by a series of metal walls that enclose the fire-box (1) with parallelepiped configuration, surrounded by six walls provided with intercommunicating spaces (A) filled with water.
  • the hot water feed union (2) is located on top of the fire-box (1), which is of course provided with the fume ejection mouth (3), on which the pipe used to convey fumes to the chimney is inserted.
  • the front wall is interrupted to create the mouth (4) used to load the wood, closed by a door (5) with shutter, which is inserted and guided between two upright guides (6) fixed outside the front wall.
  • comburent air can still enter the fire-box (1) through a series of intake openings (7) located on the front border (8) that borders the mouth (4) and comes into contact with the door (5) when the same is closed.
  • a collapsible intercepting screen (9) capable of intercepting the air flow through the openings (7) is located, thus contributing comburent air to combustion inside the fire-box (1).
  • the collapsible intercepting screen (9) can be raised or lowered automatically by means of a lever system (10) actuated by an electric engine (11) controlled by a thermostat (12) located on the control panel (13) where the user can set the water threshold temperature to turn the flame on and off.
  • a first bracket (14) projects from the back wall and transversally extends from one side to the other, being interrupted near the front wall, slightly above the mouth (4).
  • the first bracket (14) has a space that is filled with water coming from below through a first ascending pipe (15) that communicates with the space of the back wall.
  • a second ascending pipe (16) starts above the first bracket (14) and ends into the space of a second projecting bracket (17), which is fixed inside the front wall and transversally extends from one side to the other, being interrupted near the back wall, slightly above the first bracket (14).
  • the second bracket communicates with the space on top of the fire-box where the hot water feed union (2) is located.
  • brackets (15 and 17) force fumes to travel along a double serpentine which extends their permanence in the fire-box (1), thus favouring thermal exchange especially with respect to the water contained in the brackets (15 and 17), which are in contact with fumes.
  • the high downward inclination of the brackets (15 and 17) obstacles the formation of sooty deposits on the brackets.
