Liquid hydrocarbon or bioethanol heating appliance

Abstract

A liquid hydrocarbon or bioethanol heating appliance ( 10 ), typically and non critically shaped as a movable fireplace with parallelepiped configuration, comprises a base ( 16 ), opposite side bands ( 12 ) with vertical development and a top connection panel ( 14 ) extended crosswise. The base is provided with an opening ( 20 ) on the exposed top front, which can be screened with movable separators ( 32 ) and incorporates a tank ( 22 ) and a combustion chamber or burner ( 24 ) connected to the tank by a conduit ( 26 ). The appliance comprises a valve or solenoid valve ( 30 ) or ( 42 ) provided with or combined to means that detect the fuel level in the burner ( 24 ) and temporarily activate the same valves for allowing the passage of the amount of fuel required for restoring a given level in said burner.

         3 . The heating appliance according to  claim 2 , wherein the detection of fuel level is carried out by means of two or more metal electrodes ( 90 ) seated in the combustion chamber ( 24 ). 
     
     
         4 . The heating appliance according to  claim 1 , wherein the tank ( 22 ) is periodically fed by reservoir ( 60 ) through a quick coupling valve consisting of two complementary male/female elements ( 56 - 58 ) respectively fixed to the feeding tube of the fuel coming out of said reservoir and to a conduit ( 62 ) coming out of the tank ( 22 ). 
     
     
         5 . The heating appliance according to  claim 4 , wherein the tank ( 22 ) comprises a float ( 52 ) cooperating with the conduit ( 62 ), a venting valve ( 64 ) and a door ( 66 ) that closes the inlet of the same conduit ( 62 ) intercepting a microswitch connected to the electronic control unit ( 40 ) for causing the closure of said separators ( 32 ). 
     
     
         6 . The heating appliance according to  claim 5 , wherein the separators ( 32 ) are kept closed by helical springs ( 34 ) and are opened by the effect of an electrical motor ( 36 ) of the magnetic stepping type. 
     
     
         7 . The heating appliance according to  claim 1 , wherein it comprises a base ( 68 ) that supports the tank ( 22 ), the combustion chamber ( 24 ), the level adjustment device ( 44 ) and the solenoid valve ( 42 ), adjacent said combustion chamber ( 24 ) the base ( 68 ) supporting a block that forms a cavity ( 74 ) wherein there is arranged at least one electrical accumulator ( 76 ) for powering and moving the components connected to the electronic control unit ( 40 ) and the electrical motor ( 36 ) for opening the separators ( 32 ). 
     
     
         8 . The heating appliance according to  claim 1 , wherein the combustion chamber ( 24 ) is arranged between the tank ( 22 ) and the cavity ( 74 ) and comprises a cradle seat ( 78 ) extended longitudinally and hanging relative to the lower plane defined by the base ( 68 ).
