Abstract

The invention provides a stepwise air supply system and a gas water heater and relates to the field of gas water heaters. The stepwise air supply system comprises an inner cavity, an outer cavity anda combustor. The inner cavity comprises a first side wall, a second side wall, a third side wall and a fourth side wall. The combustor is arranged at one end of the inner cavity and connected with thefirst side wall, the second side wall, the third side wall and the fourth side wall, and the end, close to the combustor, of the inner cavity is sealed; and the inner cavity and the combustor are arranged in the outer cavity, and a ventilating duct is formed between the inner cavity and the outer cavity as well as between the combustor and the outer cavity. Air supply ports are formed in the first side wall, the second side wall, the third side wall and the fourth side wall correspondingly and communicate with the ventilating ducts. According to the stepwise air supply system, air and fuel gas are fully mixed and combusted, and combustion pollutant generation is reduced. The gas water heater is provided with an inner cavity and outer cavity air guide structure, air cooling of the inner cavity side walls is achieved, the situation that the inner cavity side walls have excessively high temperatures, are burnt and change colors, or are even damaged is avoided, and the service life of thegas water heater is prolonged.

Description

technical field [0001] The invention relates to the field of gas water heaters, in particular to a graded air supply system and a gas water heater. Background technique [0002] At present, the air supplement of gas water heaters is divided into primary air and secondary air. Generally, the secondary air is introduced from the bottom of the burner upwards through the gaps of each burner, supplemented with air and combusted with gas. [0003] This secondary air supply method makes the air parallel to the burning direction of the flame, resulting in a small contact area with the flame, making it difficult to mix evenly. In addition, the existing coilless gas water heater has a relatively high temperature rise because the wall is close to the flame, and the wall will be burnt, discolored or even damaged if used for a long time. [0004] Designing an air supply structure that can fully mix air and gas in the flame and effectively reduce the temperature rise of the wall surface...
