Abstract:
The present disclosure discloses a gas water heating apparatus comprising: a shell; a burner, a heat exchanger, and a fan which are disposed in sequence within the shell, wherein a combustion region is formed between the burner and the heat exchanger that are spaced from each other by a first preset distance; a first enclosing frame that encloses the combustion region, an air inlet portion being disposed on a side wall of the first enclosing frame; a heat insulating plate which is disposed within the first enclosing frame and is spaced from an inner surface of the side wall of the first enclosing frame by a second preset distance, wherein when the fan is in operation, air outside the first enclosing frame can flow into a region between the first enclosing frame and the heat insulating plate through the air inlet portion. The present disclosure provides a gas water heating apparatus having an optimized temperature reducing structure and capable of achieving a significant temperature reduction effect.

Claim (Index 13):
The gas water heating apparatus according to  claim 12 , wherein the air inlet portion directly faces the heat insulating plate, so that the air entering through the air inlet portion can directly contact the heat insulating plate and flow upwards along a gap between the heat insulating plate and the first enclosing frame, and wherein a part of the air flows out of the gap through the first hole, and the other part of the air flows out of the gap through the second hole.
