Efficient low-heat-loss storage type gas water heater

Abstract

The invention discloses an efficient low-heat-loss storage type gas water heater which comprises an inner container, a combustion chamber and a combustor, wherein a barrel body is arranged at the periphery of the inner container; a convexly mounted seal head and a concavely mounted seal head are mounted at an upper end and a lower end of the barrel body respectively; a smoke pipe is arranged between the convexly mounted seal head and the concavely mounted seal head; the combustion chamber is formed below the concavely mounted seal head and defined by a coaming, a water collection plate, a furnace door and the concavely mounted seal head; the combustor is mounted on the water collection plate; an ejection pipe is arranged at a gas inlet end of the combustor and penetrates through an opening of the combustion chamber and the furnace door in sequence, and an ejection hole of the ejection pipe is formed in an outer side of the combustion chamber. With the adoption of the storage type gas water heater, the heat loss can be reduced, and introduction of primary air and introduction of secondary air do not interfere with each other, so that full combustion of gas is guaranteed and the combustion efficiency is improved.

Description

technical field [0001] The invention relates to a water heater, in particular to a volumetric gas water heater with high efficiency and low heat loss. Background technique [0002] Generally, the volumetric gas water heater adopts atmospheric combustion. The upper end of the cylindrical inner tank is a convex head, and the lower end is a concave head. pipe as a smoke pipe. The gas is burned by the atmospheric burner installed in the combustion chamber under the recessed head of the liner, and the high-temperature flue gas generated after combustion contacts the surface of the liner on the recessed head and the smoke pipe, and transfers heat to the water stored in the liner. Atmospheric combustion is that the gas with pressure is injected into the injection port of the atmospheric burner through the nozzle, and a certain amount of air is brought in at the same time, passing through the injection tube and the cavity of the burner, and the air and gas are mixed and then flow o...

Problems solved by technology

However, the heat in the combustion chamber is easily radiated from the opening through radiation. In addition, the primary air and secondary air required for atmospheric combustion pass through the opening at the same time. The mutual influence is not conducive to combustion, and the backflow of smoke will also affect the primary air ejection.
