Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating

Abstract

Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating comprising a hearth fuelled by pellets or biomass grains, at least one plate to cook food and two heat exchangers to heat water for domestic heating wherein the cooking plate is located above the hearth fuelled by pellets or biomass grains, said two heat exchangers are positioned at the sides of the cooking plate, that on one side of said heat exchangers two inclined deflection plate are mounted that forces the combustion fumes to go up to touch the cooking plate and then to flow on the heat exchangers, the heat exchangers are two bundles with parallel pipes, on said pipes of said bundle heat exchangers at least one fixed deflection plate is located, said fixed deflection plates are perpendicular to said pipes of said bundle heat exchangers, each fixed deflection plate has a unique gateway that is positioned above or below each pipe bundle.

What is claimed is: 
     
         1 . Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating comprising a hearth fuelled by pellets or biomass grains, at least one plate to cook food and at least one heat exchanger to heat water for domestic heating characterized by the fact that the cooking plate/s is/are located above hearth fuelled by pellets or biomass grains, that said heat exchanger/s is/are positioned at the side/s of the cooking plate/s, that on one side of said heat exchanger/s at least one inclined deflection plate is mounted that forces the combustion fumes to go up to touch the cooking plate/s and then to flow on the heat exchanger/s, that the heat exchanger/s is/are a bundle with parallel pipes, that on said pipes of said bundle heat exchanger/s at least one fixed deflection plate is located, that said fixed deflection plate/s is/are perpendicular to said pipes of said bundle heat exchanger/s, that each fixed deflection plate forms a unique gateway for the combustion fumes that is positioned above or below each pipe bundle. 
     
     
         2 . Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating according to  claim 1  characterized by the fact that the pipes of said bundle heat exchanger/s tube are parallel between them and all pipes are placed perpendicular to the front and back surfaces of said stove. 
     
     
         3 . Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating according to  claim 2  characterized by the fact that the pipe bundles are two and are placed one on one side of the cooking and heating stove and one on the other side. 
     
     
         4 . Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating according to  claim 2  or  3  characterized by the fact that on the pipes of each bundle is mounted at least a movable plate to remove ash, deposits and also other combustion products from the pipes. 
     
     
         5 . Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating according to  claim 4  characterized by the fact that the movable plates to remove ash, deposits and also other combustion products from the pipes are in number equal to the number of fixed deflection plates plus one. 
     
     
         6 . Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating according to  claim 5  characterized in that the movable plates can be controlled from outside through a handle. 
     
     
         7 . Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating according to  claim 1  characterized by the fact that in each heat exchanger is placed a collection box of ashes and other combustion products that is extracted from outside. 
     
     
         8 . Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating according to  claim 1  characterized that each collection box of ashes and other combustion products has an additional compartment located under the fan for dust collection.
