Energy-saving water heater with waste heat recycling function

Abstract

The invention belongs to the technical field of household articles, and particularly relates to an energy-saving water heater with waste heat recycling function. The energy-saving water heater comprises water heater shells, wherein the front sides of the water heater shells are fixedly connected to a protective assembly through bolts, a combustor is arranged inside the water heater shell, and thecombustor is fixedly installed on the inner wall of the water heater shell. Through the arrangement of a first shell and a second shell, the hot gas generated when the combustor works can be effectively stored in a centralizing mode, so that water in a first heat conduction pipe and a second heat conduction pipe can be heated; and through the arrangement of a fan, when the fan works, the fan can blow the upwards hot gas downwards through a pipeline, and the hot gas is inhibited from being discharged, so that the interior of the first shell and the interior of the second shell can be sufficiently heated by the hot gas, then the hot gas can be effectively and reasonably utilized, the heat carried in the hot gas is prevented from being wasted, and meanwhile, the pollution to the environment is also reduced.

Description

technical field [0001] The invention belongs to the technical field of household articles, and in particular relates to an energy-saving water heater with waste heat recovery. Background technique [0002] Household items generally refer to furniture, bedding, kitchen and bathroom utensils, interior accessories and commodities needed for daily life, collectively referred to as household items. [0003] With the improvement of people's quality of life, when people wash their hands, in order to avoid cold water irritating the skin, they usually use a gas water heater to heat the cold water to make it reach a suitable temperature for people to wash. The water inlet pipe is coiled outside the combustion chamber, and the cold water is heated through the heat exchange between the water inlet pipe and the outer wall of the combustion chamber to make it heated to the set temperature, and then the flue gas after heat exchange through the main heat exchanger is discharged out of the m...

Problems solved by technology

[0003] With the improvement of people's quality of life, when people wash their hands, in order to avoid cold water irritating the skin, they usually use a gas water heater to heat the cold water to make it reach a suitable temperature for people to wash. The water inlet pipe is coiled outside the combustion chamber, and the cold water is heated through the heat exchange between the water inlet pipe and the outer wall of the combustion chamber to make it heated to the set temperature, and then the flue gas after heat exchange through the main heat exchanger is discharged out of the machine through the exhaust pipe. The exhausted exhaust gas still maintains a relatively high temperature and is directly discharged, so that the heat carried by the high-temperature exhaust gas is wasted, and it also causes serious pollution to the environment.
