Embodiment 1

[0040] Its structure of the blue flame sectional air supply gas water heater provided by the present invention is as follows: figure 2 As shown, it mainly includes: water inlet valve 1, water inlet flow sensor 2, gas valve 3, pulse igniter, multi-row fire row burner 5, heat exchanger 6 and fan, and the difference with the existing gas water heater is that : a 3-way distributor 9 is set at the gas channel position of the existing gas water heater, the gas valve is connected to the 3-way distributor 9 through 2 solenoid valves, and the 3-way distributor is formed by 2-way gas Composed of channels, the 2-way gas channels in the 3-way distributor 9 are respectively connected to the gas valves through solenoid valves, and each channel of the distributor is provided with a plurality of gas nozzles 91 (as shown in Figure 4a, Figure 4b, and Figure 5) , each gas nozzle 91 is facing the ejection hole 51 of a fire row burner 5 (see Figure 7); any solenoid valve conduction constitutes th...

Embodiment 2

[0054] It is another embodiment of the blue flame segmental air supply gas water heater of the present invention. This embodiment is basically the same as Embodiment 1, and also includes: water inlet valve 1, water inlet flow sensor 2, gas valve 3, pulse igniter , multi-row fire row burner 5, heat exchanger 6 and blower fan 7, and its difference is that the distributor is different: the distributor used in this embodiment is a 3-channel 7-way distributor, and its structure is as shown in Figure 4c. The valve is respectively connected to the 3 channels of the 7-way distributor through 3 solenoid valves, one of the 3-way distributors is provided with 4 gas nozzles, the other of the 3-way distributors is provided with 6 gas nozzles, and 3 Another road in the road distributor is provided with 8 gas nozzles, and each gas nozzle is directly facing the injection hole of a fire row burner; the fan is a 7-speed fan.

[0055] The number of fire row burners corresponding to the 7-way dis...

Embodiment 3

[0065] This embodiment is basically the same as Embodiments 1 and 2, and also includes: water inlet valve 1, water inlet flow sensor 2, gas valve 3, pulse igniter, multi-row fire row burner 5, heat exchanger 6 and fan 7 , the difference is that the distributor is different: the distributor used in this embodiment is an n-channel n-way distributor, and its structure is shown in Figure 4d. The gas valve is connected to the n-way distribution through n-1 electromagnetic valves respectively. n-1 channels of the distributor, one of the n-way distributors is directly connected to the gas valve, each distributor is provided with a plurality of gas nozzles, and each gas nozzle is directly facing the injection hole of a fire row burner; The fan is an n-speed fan.

[0066] This embodiment is more versatile and can provide more hot water with different temperatures.

Abstract

The present invention relates to a water heater, in particular to a blue flame segmental air supply gas water heater, comprising: a water inlet valve, a water inlet flow sensor, a gas valve, a pulse igniter, a multi-column fire row burner, a heat exchanger and The fan is characterized in that it is provided with an n-way distributor, the gas valve is connected to the n-1 distributor through n-1 solenoid valves, and one of the n-way distributors is directly connected to the gas valve, Each distributor is provided with a plurality of gas nozzles, and each gas nozzle is directly facing the injection hole of a fire row burner; the fan is an n-speed fan. Divide the air intake channel into multi-stage control, combined with multi-speed variable speed fans to correspond to the low fire, medium fire, and high fire of the burner, so that the excess air coefficient α during combustion is always maintained within the range of 1.5, so that the burner burns in the best state , the content of CO in the flue gas is below 300PPm, and the thermal efficiency is higher than 88%.

Description

technical field [0001] The invention relates to a gas water heater, in particular to a blue flame gas water heater capable of fully burning gas. Background technique [0002] Gas water heater is a kind of water heater widely used in households at present. It has the advantages of small size, fast heating speed and instant heating. The development trend of technology. For gas water heaters, it is a long-term continuous improvement goal to improve combustion thermal efficiency and reduce exhaust emissions. [0003] The structure of the existing closed gas water heater is as follows: figure 1 As shown, it mainly includes: water inlet valve 1, water inlet flow sensor 2, gas valve 3, pulse igniter (not shown in the figure), gas channel 4, multi-row fire row burner 5, heat exchanger 6, fan 7 and components such as smoke collecting hood 8 constitute. The water from the tap water pipe enters the water pipe of the heat exchanger 6 through the water inlet valve 1 and the water inl...
