Claims

[Scope of utility model registration request]

An inner tube with an open end that forms an exhaust passage for exhausting combustion exhaust gas from the combustion device to the outside, and a supply tube that encloses this inner tube and takes in combustion air from outside to the combustion device around the outside of the inner tube. The jacket tubular body is composed of an outer tube with an open tip that forms an air passage, and the outer tube has an air supply guide that expands in the radial direction at the tip thereof, and the air supply guide is provided at the tip of the inner tube. An exhaust chamber structure is provided so that an air supply port is formed on the outside of the outer diameter of the outer tube with the air supply guide, and the exhaust chamber structure is located at the center of the air supply guide and the exhaust chamber structure. The line coincides with the center line of the wall penetrating sleeve which is eccentric with respect to the center line of the jacket tube body, and an exhaust port part is provided eccentrically with respect to the inner pipe at the center of the tip side of the exhaust chamber structure. The air supply and exhaust pipe top of an air conditioner/heater is characterized by:
