Claims

[Scope of utility model registration request]

(1) In a hot-air heater that blows air to a heat exchanger to obtain hot air, the heat exchanger is connected to a combustion chamber provided along a burner, and from the combustion chamber along the longitudinal direction of the combustion chamber. It is formed from U-shaped heat exchange pipes that extend upward, make a U-turn in the middle, and are connected to an exhaust header that is arranged parallel to the combustion chamber. A hot air heater characterized in that the replacement pipes are arranged in a staggered manner to increase the contact area with the blown air.

(2) The hot air heater according to claim 1, wherein the heat exchange pipes are arranged in a staggered manner.

(3) The hot air heater according to claim 1 or 2, wherein the heat exchange pipes are arranged so that the heights of the U-turn portions thereof are different.

(4) The hot air heater according to claim 1, 2, or 3 of the utility model registration claim, characterized in that the U-turn portion of the heat exchange pipe is bulged.

(5) Utility model registration claims 1, 2, 3 or 3, characterized in that the exhaust header is provided with an inclined surface that guides the air blown from below to the high temperature side of the heat exchange pipe. 4
Warm air heater as described in section.
