Abstract

The invention discloses a condensed gas water heater, which is characterized in that: a main heat exchanger (7) and an auxiliary heat exchanger (8) inside are arranged from upper to lower in sequence, and waterways of the two are connected through pipelines. The invention is characterized in that: the lower end of the auxiliary heat exchanger (8) is formed with a water collecting cavity (8-1) in one body; a smoke cap is positioned outside the auxiliary heat exchanger (8-1); a smoke discharge cylinder is arranged in the middle of the auxiliary heat exchanger (8), which is communicated with the water collecting cavity (8-1) with the lower end and the upper end extending out from the auxiliary heat exchanger. The invention has the advantages of simple structure, high heat efficiency and the integration of functions as heat collecting and exchanging, condensed water collecting and smoke discharging.

Description

technical field [0001] The invention relates to a gas instant water heater, and more specifically relates to a condensing gas instant water heater and a flue gas layout. Background technique [0002] In today's situation of increasingly tight energy sources and rising prices, condensing gas instant water heaters have attracted attention from all aspects because their thermal efficiency is more than 12% higher than ordinary gas instant water heaters. Now many companies have launched condensing water heaters, but now There are two main layouts for heat exchangers and flue gas flow of condensing gas instant water heaters, each of which has its own shortcomings. [0003] The heat exchanger of the condensing gas instant water heater generally adopts two heat exchangers, which can reduce the cost. The heat exchanger for the first heat exchange is called the main heat exchanger, and most of the heat exchange is completed in this heat exchanger. The structure of this heat exchanger...
