Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, a water-cooled fully premixed gas water heater includes a combustion chamber 1, a main heat exchanger 2, a cylindrical heat exchange coil 21, a burner 6 and a smoke collection hood 3, and the heat exchange coil 21 surrounds the combustion chamber 1. The smoke collecting hood 3 is set on the upper opening of the combustion chamber 1. The main heat exchanger 2 is arranged on the top of the combustion chamber, the smoke collecting hood 3 is arranged on the upper opening of the combustion chamber 1 , and the burner 6 is arranged at the lower end of the combustion chamber 1 .

[0028] It also includes a fan 4 and a gas proportional valve 5;

[0029] Such as figure 2 , image 3 As shown, the burner 6 includes a combustion plate 61, a base 62 with an upper opening, a splitter plate 63 and a preheating heat exchanger 64 with several guide...

Abstract

The invention discloses a water-cooled full-premixing gas water heater. The water-cooled full-premixing gas water heater comprises a main heat exchanger, a cylindrical heat exchange coil pipe, a burner, a fume collecting hood and a main controller. The main heat exchanger is arranged on the upper portion of the cylindrical heat exchange coil pipe. The water-cooled full-premixing gas water heater further comprises a draught fan and a gas proportional valve. A gas mixing pipe is arranged at a gas inlet in a bottom plate of a burner base. The gas inlet end of the gas proportional valve is communicated with a gas source. The gas outlet end of the gas proportional valve is communicated with a radial gas inlet of the gas mixing pipe. The air outlet end of the draught fan is communicated with the axial lower end of the gas mixing pipe. A preheating heat exchanger is communicated with the heat exchange coil pipe and also communicated with a water source. By the adoption of the structure, cold water is preheated in the water-cooled burner through the preheating heat exchanger, heat energy is fully utilized on one hand, and it is guaranteed that flames are stable on the other hand; the cold water preheated through the preheating heat exchanger then enters the main heat exchanger, heat energy is fully utilized, and the purpose of saving energy is realized. Through the arrangement of the draught fan, it is guaranteed that primary air is sufficient, the primary air and fuel gas are fully premixed, the fuel gas is fully burnt, and energy is saved.

Description

technical field [0001] The invention relates to a gas water heater. Background technique [0002] In the current prior art, a gas water heater includes a combustion chamber, a burner, a main heat exchanger and a smoke collection hood, the main heat exchanger surrounds the combustion chamber, the smoke collection hood is arranged on the upper opening of the combustion chamber, and the burner is arranged on The lower end of the combustion chamber has a gap between the burner and the lower end of the combustion chamber. Existing problems are: the temperature of the burner rises, the waste of heat energy cannot be utilized, the primary air is insufficient, and the combustion is insufficient. Contents of the invention [0003] The object of the present invention is to provide a water-cooled fully premixed gas water heater, which can utilize the temperature rise heat energy of the burner to preheat cold water to achieve the purpose of energy saving. [0004] The present invent...
