CLEANING DEVICE FOR WICK BURNER

摘要

A burner of wick type is disclosed which secures user safety by stopping combustion through an oxygen depletion protection function in the event of an oxygen depletion. When tar is accumulated in the wick, the wick is burnt to clean the tar with the liquid fuel supply cut off, thus burning out the liquid fuel contained in the wick. In the process, the combustion temporarily becomes unstable and a great amount of carbon monoxide is generated, resulting in a state similar to oxygen depletion. In a burner with an oxygen depletion protection function, the combustion is stopped during the wick cleaning, with the result that most of the tar accumulated in the wick remains unburnt, adversely affecting both the fuel absorption characteristic and service life of the wick. This invention is such that the oxygen depletion protection function is not operated during the wick cleaning. The tar accumulated in the wick is mostly burnt out and thus the deterioration of the fuel absorption characteristic is prevented thereby improving the service life of the wick.
