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

A water-cooled fully premixed gas water heater, including a main heat exchanger, a cylindrical heat exchange coil, a burner, a smoke collection hood and a main controller, and the main heat exchanger is arranged on the upper part of the cylindrical heat exchange coil , also includes a fan and a gas proportional valve; the air inlet hole on the bottom plate of the burner base is provided with a gas mixing pipe; the gas proportional valve inlet is connected to the gas source, and the gas outlet of the gas proportional valve is connected to the gas mixing The radial air inlet of the fan is connected, the air outlet end of the fan is connected with the axial lower end of the gas mixing pipe; the preheating heat exchanger is connected with the heat exchange coil, and the preheating heat exchanger is connected with the water source. Due to the adoption of such a structure, the preheating heat exchanger preheats the cold water in the water-cooled burner, one is to make full use of heat energy, and the other is to ensure the stability of the flame; the cold water preheated by the preheating heat exchanger then enters the main heat exchanger , make full use of heat energy, and achieve the purpose of energy saving. The setting of the fan ensures that the primary air is sufficient and fully premixed with the gas, so that the gas is fully combusted and energy-saving.

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...
