PURPOSE:To eliminate backfire toward the lower part of a combustion tube and permit to use the titled device safely by releasing air, which enters into a chamber of upper part of a cabinet, through an opening to keep the balance of air pressure in the combustion tube. CONSTITUTION:A cabinet 1 is provided with an opening 1a at the back surface thereof while a front reflecting board 10 is provided with the opening 10a. The rear end of a lower reflecting board 3a is abutted against the back wall of the cabinet 1 to partition a cavity 9 from the lower chamber of the cabinet 1 in substantially closed condition. According to this method, air, coming from the front side of a kerosene stove is released to the outside of the stove from the upper chamber, partitioned by the lower reflecting board 3a, through the openings 10a, 1a. On the other hand, the air in the lower chamber will never be released to the outside of the stove through the openings 10a, 1a. Accordingly, the balance of air pressure in the lower chamber is kept by air, entered through gaps, and the backfire toward the lower part of the combustion tube is eliminated whereby the stove may be used safely. |
