Problems solved by technology

Among them, the disadvantage of the top-mounted condensing gas water heater is that the structure is complex, and the two heat exchangers are distributed up and down, resulting in a large body size and inconvenient installation; although the split type condensing gas water heater is more convenient to install, the two heat exchangers are completely Separated, takes up a lot of space, obviously not suitable for small bathrooms

Embodiment Construction

[0019] Such as Figure 1-Figure 3 As shown, a condensing gas water heater of the present invention includes a shell 6 and a burner 7 disposed therein, a main heat exchanger 8 and a condensing heat exchanger 9, and the main heat exchanger 8 and the condensing heat exchanger 9 are integrated The structure is distributed in inner and outer layers, and a partition plate 10 is arranged between the main heat exchanger 8 and the condensing heat exchanger 9 . The clapboard 10 is provided with outward flanging holes, which can prevent the condensed water from the condensation section from flowing into the main heat exchange section; and the air flow gradually increases from top to bottom, and the air flow is evenly distributed, which can strengthen heat exchange, and the high-temperature flue gas generated after combustion passes through the guide After the flow plate flows out to the surroundings, it performs a heat exchange with the inner pipeline. After the heat exchange, the high-t...

Abstract

The invention discloses a condensing gas water heater, which comprises a shell and a burner, a main heat exchanger and a condensing heat exchanger which are arranged in the shell. The condensing gas water heater is characterized in that: the main heat exchanger and the condensing heat exchanger are of an integrated structure and distributed in an inner-layer and outer-layer way; and a clapboard is arranged between the main heat exchanger and the condensing heat exchanger. The condensing water heater has the advantages of capability of enhancing the heat exchange function, simple and compact structure, convenience for installation and maintenance and favorable popularization value.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a condensing gas water heater. Background technique [0002] Compared with ordinary gas water heaters, condensing gas water heaters have an additional stage of condensing heat exchangers, which preheat cold water by absorbing high-temperature flue gas, and use ordinary gas water heaters as exhaust heat to increase thermal efficiency by more than 15%. Compared with traditional Gas instant water heaters have a higher thermal efficiency of more than 96%, while in the national standard GB6932-2001 "Household Gas Instant Water Heaters", the thermal efficiency requirements for traditional gas instant water heaters are only above 84%. At the same time, the neutralizer is used to treat the discharged condensed water harmlessly, so as to truly realize energy saving and environmental protection. When an ordinary gas water heater is working, it will emit a large amount of flue gas wi...
