Abstract

The invention relates to a combustion heat exchange assembly and a gas water heater. The combustion heat exchange assembly comprises a combustor body and a pot. The pot is arranged on the combustor body, so that a flame of the combustor body can directly act on the bottom wall of the pot. The pot is provided with a water outlet located at the position in contact with the bottom wall of the pot. The bottom wall of the pot is provided with multiple concave portions which are recessed from the outside face to the inside face, so that the heat exchange area of the bottom wall of the pot is increased, and the heat exchange efficiency is improved. Multiple concave portions are arranged in a spaced manner. A flow guiding passageway is formed between the concave portions on the inner side face ofthe bottom wall and communicates with the water outlet, so that water in the pot can be completely discharged from the water outlet, and the situation that when the temperature is lowered and freezinghappens, the pot is frozen to be cracked is avoided. The situation that since the concave portions are arranged to increase the heat exchange area of the bottom wall of the pot, interruption of the water flow is formed, and the water cannot be completely discharged is avoided; and in this way, the combustion heat exchange assembly can improve the heat exchange efficiency and also can achieve theanti-freezing purpose.

Description

technical field [0001] The invention relates to the technical field of domestic electrical appliances, in particular to a combustion heat exchange component and a gas water heater. Background technique [0002] Gas water heaters are mainly divided into coil type and pot type. Among them, the coil type refers to that the coil is wound outside the heat exchanger, so that the flue gas formed by the combustion of the burner is separated from the water in the coil when it circulates in the heat exchanger. Heat exchange to heat water; the pot type refers to setting the pot directly on the burner, so that the flame burned by the burner directly acts on the pot to heat the water in the pot. When there is no need to provide hot water, if there is water stored in the pot, there is a risk of freezing and cracking. Improving heat exchange efficiency is the main direction of water heater design and research, but it is difficult to have both antifreeze and heat exchange efficiency in gen...
