Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of A of FIG. 1;

FIG. 3 is a schematic view showing a structure in which a water pipe in a combustion chamber is connected to a heat exchanger.

The specific implementation mode is as follows:

as shown in fig. 1, a constant temperature gas water heating apparatus includes a housing 1, a gas heating unit is provided in the housing 1, and a water tank 10 is provided at one side of the gas heating unit. An inverted cone-shaped smoke exhaust hood 16 is arranged at the top of the shell 1 above the fuel gas heating unit and the water tank 10, and a smoke exhaust pipe 17 communicated with the outside of the shell 1 is arranged at the top of the smoke exhaust hood 16.

The gas heating unit comprises a combustion chamber 8, a water inlet pipe 2 is arranged in the combustion chamber 8, one end of the water pipe 2 is communicated with the lower part of a water tank 10, and the other end of the water pipe extends out of the combustion chamber 8 and then extends out of the shell 1 downwards and is communicated with an external water source.

As shown in fig. 1 and 3, the water pipes 2 in the combustion chamber 8 are distributed in a serpentine shape, and heat exchange strips 2a are wound on the pipe body, a group of heat conducting legs 2b extending outwards are further arranged on the heat exchange strips 2a, a shell 22 is arranged outside the water pipes 2, and fine sand 22a is arranged between the shell 22 and the water pipes 2. The casing 22 is a tubular casing formed by two groove-shaped shells which are mutually buckled together, and a cover 22b is arranged on the casing 22 so as to prevent fine sand from leaking.

Two heat exchangers 9 are respectively arranged on two sides of the shell 22, and one end of each supporting leg 2b extends out of the shell 22 and is matched and connected with the corresponding heat exchanger 9. When the heat exchanger is heated, heat can be transferred to the water pipe through the support legs and the heat exchange strips more quickly, and the water temperature in the water pipe is accelerated to rise. Also can heat the fine sand simultaneously, the fine sand can keep warm to the water storage in the water pipe when gas heater closes, and when gas heater opened, the fine sand can carry out preliminary preheating to the cold water in the water pipe again simultaneously for the temperature of flowing into in the water tank can not hang down excessively.

The bottom of the combustion chamber 8 is connected with a burner 7, and a burner port at the top of the burner 7 extends into the combustion chamber 8 so as to heat the serpentine water pipe in the combustion chamber 8 and a heat exchanger on the serpentine water pipe.
