Alcohol stove and method for igniting an alcohol stove

Abstract

The present invention relates to an alcohol stove comprising a casing ( 10 ), whereby the housing comprises one or several fire hearths ( 17 ) and encases a fuel container ( 22 ) and a burner arrangement ( 20 ), wherein a heating wire ( 101 ) is arranged above the opening ( 25 ) of the fuel container ( 22 ) and that the heating wire ( 101 ) is connected to a connectable electrical power source, which when connected causes the heating wire ( 101 ) to heat up so that the heating wire ( 101 ) by heat radiation evaporates the fuel in the fuel container ( 22 ) such that the alcohol stove is ignited by the fuel fume vapours being ignited as they pass the heating wire ( 101 ).

1 . An alcohol stove comprising a housing ( 10 ), wherein the housing comprises at least one fire hearth ( 17 ) and encases a fuel container ( 22 ) and a burner arrangement ( 20 ) characterized in an electric ignition device, which is connectable to an electrical power source, wherein said ignition device comprises a heating wire ( 101 ) and a switch ( 107 ) arranged to be enabled to be connected together to constitute a closed electric circuit, wherein the heating wire ( 101 ) is arranged above an opening ( 25 ) of the fuel container ( 22 ) and connected to said power source via said switch ( 107 ), wherein the heating wire ( 101 ) is arranged to be heatable in order to, by heat radiation, evaporate fuel in the fuel container ( 22 ) such that said alcohol stove is ignited by ignition of fuel fume vapours as they pass the heating wire ( 101 ). 
   
   
       2 . An alcohol stove according to  claim 1 , characterized in that the heating wire ( 101 ) is arranged 1-10 mm above the opening of the fuel container ( 22 ). 
   
   
       3 . An alcohol stove according to  claim 1 , characterized in that the heating wire ( 101 ) is arranged approximately 5 mm above the opening of the fuel container ( 22 ). 
   
   
       4 . An alcohol stove according to any of the preceding claims, characterized in that said power source consists of a built-in battery. 
   
   
       5 . An alcohol stove according to any of  claims 1 - 3 , characterized in that said power source consists of an external power source to which the alcohol stove can be connected. 
   
   
       6 . An alcohol stove according to any of the preceding claims, characterized in that heating wire ( 101 ) is made from any of a ceramic composite material, metal or other electrically heatable material. 
   
   
       7 . An alcohol stove according to any of the preceding claims, characterized in that said switch ( 107 ) consists of a micro switch ( 107 ) that is closed automatically when a knob ( 105 ) arranged in said housing ( 10 ) is turned maximally, remains closed as long as the knob ( 105 ) is kept in this position and opens when the knob ( 105 ) is released. 
   
   
       8 . An alcohol stove according to any of  claims 1 - 6 , characterized in that the electric ignition device further comprises an electric circuit comprising logic with timing capabilities, wherein said electric circuit is automatically activated when a knob ( 105 ), arranged in said housing ( 10 ), is turned and initiates simultaneously a countdown of a predetermined length and supplies voltage to the heating wire ( 101 ), remains active as long as the countdown proceeds and disrupts the supply of voltage to the heating wire ( 101 ) as the countdown has been completed. 
   
   
       9 . An alcohol stove according to any of  claims 1 - 6 , characterized in that said switch ( 107 ) consists of a micro switch ( 107 ) that is arranged to be closed automatically when an activation arrangement, such as a knob ( 106 ) or a button ( 106 ) arranged in said housing ( 10 ), is activated, remains closed as long as the knob ( 106 ) is kept in its turned position or the button ( 106 ) is being pressed and opens when the knob ( 106 ) is turned back or the button ( 106 ) is released. 
   
   
       10 . Method for igniting an alcohol stove comprising a housing ( 10 ), wherein the housing comprises at least one fire hearth ( 17 ) and encases a fuel container ( 22 ) and a burner arrangement ( 20 ) characterized in connecting a heating wire ( 101 ) arranged above the opening ( 25 ) of the fuel container ( 22 ) via a switch ( 107 ) to a power source that when connected brings the heating wire ( 101 ) to heat up so that the heating wire ( 101 ) by heat radiation evaporates the fuel in the fuel container ( 22 ) so that the alcohol stove is ignited by the fuel fume vapours being ignited as they pass the heating wire ( 101 ).
