Description

Technical Field

[0002] A gas water tank is a device for heating water. Generally, a circulation system is arranged inside the water tank inner liner. By installing a circulation water pump on the water tank inner liner, a heat exchanger is connected inside the water tank. The heat exchanger is directly heated by a combustion system; the circulation water pump, the heat exchanger and the water tank inner liner form a water circulation structure; after the heat exchanger absorbs the heat generated by the burner, the heated water in the heat exchanger re-enters the water tank inner liner for homogenization to achieve the heating effect of the water body in the water tank inner liner. Then the external water path to be heated (generally in a coil structure) enters the water tank inner liner and exchanges heat with the circulating water in the water tank inner liner through the tube wall of the coil structure to realize the heating of the water body in the coil.

[0003] However, in the existing gas water tank structure, although most of the heat after combustion is absorbed by the heat exchanger, the heat remaining in the combustion flue gas is directly discharged from the gas water tank, resulting in waste of heat and reduction of thermal efficiency.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0008] Further, the top end of the smoke pipe is connected with a condenser; the smoke inlet pipe of the condenser is connected to the smoke exhaust port of the smoke pipe; a condensation pipeline is arranged inside the condenser; the circulating water path is connected inside the condensation pipeline.

[0009] Further, an outer shell is sleeved outside the water tank inner liner; a heat insulation structure is arranged between the outer shell and the water tank inner liner; a top cover is sleeved outside the condenser; the top cover is fixed on the outer shell.

[0010] Further, a filter mesh cover is fixed at the bottom of the water tank inner liner; the filter mesh cover is sleeved outside the burner.

[0011] Further, the heating plate is in the shape of a hemispherical shell; the cross-sectional diameter of the heating plate gradually decreases in the direction closer to the smoke pipe.

[0012] Further, the smoke pipe is coaxially arranged with the inner tank of the water tank.
