Kerosene heater

Abstract

A kerosene heater is provided with a structure of a combustion chamber capable of continuing combustion in a stabilized flame condition and prevents a state of an incomplete combustion condition perfectly. The kerosene heater of the invention is a type wherein kerosene supplied from a kerosene supply chamber is combusted in a combustion chamber between an inner flame cylinder and an outer flame cylinder positioned in an outer cylinder, respectively, and the kerosene supply chamber and a kerosene storage chamber provided at the outer periphery of the kerosene supply chamber are connected to each other by two communication pipes, wherein blast processing is applied to the inner flame cylinder and the outer flame cylinder at least at the combustion chamber side, which has a rough surface.

What is claimed is  
     
         1 . A kerosene heater comprising a kerosene supply chamber, a kerosene storage chamber and a combustion chamber comprising inner flame cylinder and an outer flame cylinder, in which a kerosene storage chamber connected to the kerosene supply chamber by two communication pipes, wherein at least the surface the combustion chamber side of the inner flame cylinder and the outer flame cylinder have a rough surface by blasting.  
     
     
         2 . The kerosene heater according to the  claim 1 , wherein the blasting is applied after the formation of the inner flame cylinder and the outer flame cylinder.  
     
     
         3 . The kerosene heater according to the  claim 1 , wherein both the inner flame cylinder and the outer flame cylinder are made up of a lustrous stainless plate.  
     
     
         4 . The kerosene heater according to the  claim 1 , wherein an inner peripheral surface of the outer cylinder is black.  
     
     
         5 . The kerosene heater according to the  claim 1 , wherein both the inner flame cylinder and the outer flame cylinder are made up of the lustrous stainless plate, and the blast processing is applied after the formation of the inner flame cylinder and the outer flame cylinder.  
     
     
         6 . The kerosene heater according to the  claim 1 , wherein both the inner flame cylinder and the outer flame cylinder are made up of the lustrous stainless plate, and an inner peripheral surface of the outer cylinder is black.
