| 摘要 |
The invention relates to an appliance for heating fluids which includes a combustion chamber (20) in which the head (21c) of the burner with flame openings (39) is juxtaposed with a wall (21a, 21b) which separates the chamber from the lower portion of the appliance; in the event of flammable substances bieng present in the environment surrounding the appliance, these can enter the combustion chamber only through the flame openings (39) and similar slots (50) formed in the wall (21a, 21b). This enables the burner flames and/or the ignition element (25) to ignite these substances as soon as they enter the chamber (20), the flames being detached from said wall, thus preventing the formation of unwanted explosive or flammable mixtures in the chamber (20) and any flash back, thereby contributing to the safety of the appliance.
