High output heating device

Abstract

The invention concerns a multiple-fuel heating apparatus wherein: the combustion chamber ( 1 ) forms the main support structure of the heating apparatus and is made of sheet metal bent and welded ( 2 ) so as to be completely sealed, optionally except at the joint with said door; the elements ( 20 ) forming the outer cover are fixed to the combustion chamber, the fixing elements not passing through the chamber and said elements not being necessarily fixed together.

1 . Multi-fuel heating device comprising: 
 a combustion chamber ( 1 ) making up the main carrier structure of said device, made of folded and weldable sheet metal ( 2 ), preferably steel, obtained by the welded assembly of a rear wall, two lateral walls, a lower wall and an upper wall, said chamber having predetermined standard dimensions depending on the nominal power required,    a device for the inlet of cold external air comprising a first damper or valve ( 15 ) which may be open in a variety of positions intermediate between a totally closed position and a totally open position,    at least one outlet device ( 30 ) for the burnt gases connected to said chamber,    a front access door ( 3 ), possibly provided with a window ( 9 ), connected to the combustion chamber,    the combustion chamber ( 1 ) thus being almost sealed, i.e. sealed except at the level of said device for cold air inlet, of said outlet device for the burnt gases and possibly of the door joint, characterised in that said damper or valve ( 15 ) can be activated by a motor ( 16 ) itself controlled by a cordless remote control ( 17 ), said remotely controllable device for air inlet co-operating with the quasi-seal of the chamber in order to allow almost instantaneous remote control of the flame by the user.    
   
   
       2 . Heating device according to  claim 1 , wherein the reaction time of the flame to the control is of a few seconds.  
   
   
       3 . Device according to  claim 1 , further comprising elements ( 20 ) such as plates made of cast iron, ceramic, enamel or firestone, said elements ( 20 ) forming an outer hood fixed to the combustion chamber, without the fixation means passing through the chamber, i.e. without breaking the seal, and without said elements ( 20 ) necessarily being fixed to each other.  
   
   
       4 . Heating device according to  claim 3 , wherein the elements of the hood ( 20 ) are fixed to the combustion chamber by screws, rivets, glue or putty.  
   
   
       5 . Heating device according to  claim 1 , wherein the cordless remote control ( 17 ) is an infrared or ultrasound remote control.  
   
   
       6 . Heating device according to  claim 1 , wherein the opening or closing of the first damper ( 15 ) is controlled by a timer.  
   
   
       7 . Heating device according to  claim 1  wherein the opening or closing of the first damper ( 15 ) is carried out at a pre-programmed value by a presence detector in a volume, preferably an infrared sensor.  
   
   
       8 . Heating device according to  claim 1 , comprising a heating duct ( 6 ) for the external air in contact with the combustion chamber ( 1 ), before it enters the latter, said duct terminating in a neck ( 7 ) and opening into the upper part ( 10 ) of the chamber near its front face ( 9 ).  
   
   
       9 . Heating device according to  claim 1 , further comprising a duct ( 6 ′) provided with a second damper or valve ( 18 ) to guide secondary air from the outside towards the chamber ( 1 ), said damper ( 18 ) being controllable by the user.  
   
   
       10 . Heating device according to  claim 1 , wherein the remote control ( 17 ) is provided with a thermostat and/or a digital programmer, and possibly a display means, preferably with liquid or electroluminescent crystals.  
   
   
       11 . Heating device according to  claim 3 , wherein the combustion chamber has protrusions ( 4 ′,  4 ″) that allow external covering elements ( 20 ) to be attached to the device such as plates, feet or cooking plates made of cast iron, ceramic, enamel or firestone.  
   
   
       12 . Heating device according to  claim 1 , comprising a heating device using gas of the type with a stack or vent-hole, using liquid fuel, in particular by evaporation under pressure or with gasification under atmospheric pressure, using wood, coal or another solid fuel.
