Problems solved by technology

[0005] When the flue gas is discharged, if it is blocked or not smooth, it will affect the normal operation of the volumetric gas water heater, but if the flue gas is discharged too quickly, the heat exchange with the water in the water tank 12 may not be complete, resulting in the temperature of the discharged flue gas is still high , the heating efficiency of the volumetric gas water heater is affected

Abstract

The invention discloses a volume type gas water heater, which comprises a shell, a water tank, a burner arranged at the bottom of the water tank, a first heat exchange channel which passes through the top and the bottom of the water tank, and a second heat exchange channel which passes through the top and the side face of the water tank, wherein a sealing boss is arranged on the circumferential inner wall of the shell; the sealing boss presses against the periphery of the water tank, so that the periphery of the water tank is divided into a top heat exchange cavity and a side face heat exchange cavity; the second heat exchange channel is communicated with the top heat exchange cavity and the side face heat exchange cavity; and high temperature gas is subjected to three heat exchange processes in the first heat exchange channel, the second heat exchange channel and the side face heat exchange cavity sequentially before flowing out of the shell. Compared with the prior art that the high temperature gas only exchanges heat in the first heat exchange channel and the side face heat exchange cavity, the water heater has the advantages that the heat exchange channel for the high temperature gas is extended; therefore, the heat exchange time for the gas and water in the water tank is prolonged, the heat exchange is more sufficient and the heating efficiency of the water heater is improved.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a volumetric gas water heater. Background technique [0002] Volumetric gas water heaters are widely used in household hot water supply, and their heating and heat exchange efficiency is a concern of many users in the application. [0003] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a typical volumetric gas water heater in the prior art, and the direction indicated by the arrow in the figure is the flow direction of the heating flue gas. [0004] The volumetric gas water heater comprises a shell 11 and a water tank 12 located in the shell 11. The bottom, bottom and surroundings of the water tank 12 are all at a certain distance from the shell 11 to form a heat exchange chamber. The bottom of the water tank 12 is provided with a burner 13. The heat exchange tube 14 for water and air heat exchange runs through the top and bottom of the water tank 12, ...
