Embodiment 1

[0039] 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 of the distributors is provided with a plurality of gas nozzles 91 (such as Figure 4a , Figure 4b , Figure 5 shown), each gas nozzle 91 is facing the injection hole 52 of a fire row burner 5 (referring to Figure 7); any solenoid valve conduction const...

Embodiment 2

[0053] 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-column fire row burner 5, heat exchanger 6 and blower fan 10, and its difference is that distributor is different: the used distributor of present embodiment is 3 passages 7 road distributors, and its structure is as follows Figure 4c As shown, the gas valve is respectively connected to the 3 channels of the 7-way distributor through 3 solenoid valves, one of the 7-way distributors is provided with 4 gas nozzles, and the other of the 7-way distributors is provided with There are 6 gas nozzles, and the other one of the 7-way distributors is provided with 8 gas nozzles, and each gas nozzle is facing the injection hole of a fire row burner; the fan is a 7-speed fan.

[0054] The number of fire row burners corresp...

Embodiment 3

[0064] 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 10 , 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 as follows Figure 4d As shown, the gas valve is respectively connected to the n-1 channels of the n-way distributor through n-1 solenoid valves, one of the n-way distributors is directly connected to the gas valve, each distributor A plurality of gas nozzles are provided, and each gas nozzle is directly facing the injection hole of a fire row burner; the fan is an n-speed fan.

[0065] This embodiment is more versatile and can provide more hot water with different temperatures.

Abstract

The invention relates to a water heater, in particular to a blue flame gas water heater with air supply by stages, comprising a water inlet valve, a water inflow inductor, a gas valve, a pulse igniter, a burner with multi-row grates, a heat exchanger and a blower, which is characterized in that a distributor with n routes is arranged, the gas valve is connected with the n-1 routes of the distributor through n-1 solenoid valves, one route of the distributor with n routes is directly connected with the gas valve, a plurality of gas nozzles are arranged on each route of the distributor, each gasnozzle is opposite to an injector hole of the grate burner; the blower is with n speed, the air inlet passage can be divided into multiple sections for control, the blower with multiple gears and variable speed is used to control separately the low fire, the intermediate fire and the high fire of the gas burner and keep the excess air ratio Alpha within the range of 1.5 when burning and keep the gas burner in optimal combustion state, the content of CO in fume is less than 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...
