In the technical scheme, a dial device is arranged ON the gas device, wherein the dial device comprises a plurality of dial switches, and each dial switch can be switched between an ON state and an OFF state. Therefore, the on-off states of the dial switches arranged in sequence can form a binary code with the same number of digits as the dial switches, so that the actual parameter information of different smoke exhaust pipelines can be expressed.

Therefore, after the on-off states of the plurality of dial switches are obtained, the corresponding parameter data of the smoke exhaust pipeline can be inquired in the prestored comparison table according to the on-off states, the actual parameter information of the current smoke exhaust pipeline is determined, and the target working parameters are further determined according to the actual parameter information of the smoke exhaust pipeline, so that the gas device can be ensured to operate at higher combustion efficiency, and the problems that the smoke exhaust pipeline resonates and squeals, the waste emission does not reach the standard and the like are avoided.

Specifically, for example, it is assumed that 4 dial switches are provided on the dial device, and when the dial switches are in the "on" state, the dial switches represent the number 1, and when the dial switches are in the "off" state, the dial switches represent the number zero. The dialing device may be switched between 24 states in total, i.e. 16 states, representing different parameters of the smoke exhaust duct.

setting the 1 st and 2 nd dials to be ON, and when the other dials are OFF, setting the corresponding parameters of the smoke exhaust pipeline to be [40, 50 ] th grade 5;

and setting the 2 nd and 3 rd dials to be ON, and setting the parameters of the corresponding smoke exhaust pipeline to be [50, 60] th gear when the rest dials are OFF.

The detailed control relationship can be seen in table 1 below:

TABLE 1

When the gas water heater leaves a factory, any one of the gears in the table 1 can be used as a default gear, for example, the actual parameter information of the first-gear smoke exhaust pipeline is used as the actual parameter information of the initial smoke exhaust pipeline, and the working parameters of the gas water heater are correspondingly set.

When the gas water heater is installed, the corresponding parameter gear of the smoke exhaust pipeline is determined according to the length of the actual smoke exhaust pipeline required by the actual installation condition, and the on-off state of the dial device is correspondingly adjusted, so that the setting is completed, and the gas water heater can play the best performance under the parameters of different smoke exhaust pipelines.

Because the parameters of the components of the gas devices, such as the gas water heater or the wall-mounted furnace, may have tolerances, it cannot be guaranteed that each individual can exert the best performance under the parameters of different smoke exhaust pipelines, so that the parameter difference between the parameters of the smoke exhaust pipelines of different grades and the parameters of a certain grade of smoke exhaust pipeline can be calculated by testing the most parameters of a plurality of gas devices under the parameters of different smoke exhaust pipelines, for example, the parameter difference between the grade 3 and the grade 1 is calculated, and the average value is calculated.

Specifically, the controller stores a parameter of a certain gear smoke exhaust pipeline as a default parameter, taking the default parameter as a parameter of a first gear smoke exhaust pipeline as an example, the corresponding working parameters include a maximum secondary pressure of a gas proportional valve, a maximum fan rotating speed, a minimum secondary pressure of the gas proportional valve, a minimum fan rotating speed, a secondary ignition pressure of the gas proportional valve, an ignition fan rotating speed and the like, and adjustment values between parameters of other gear smoke exhaust pipelines and a parameter of a 1 st gear smoke exhaust pipeline are stored, and the adjustment values are specifically the average values.

When the smoke exhaust pipeline is delivered from a factory, a default first-gear parameter is set as a default working parameter, when the smoke exhaust pipeline is installed, a corresponding parameter gear of the smoke exhaust pipeline is determined according to the actual length of the smoke exhaust pipeline at the installation place, the on-off state of the dial device is correspondingly adjusted, the controller calculates a target working parameter according to an adjustment value between the parameter gear of the actual smoke exhaust pipeline and the parameter gear of the current smoke exhaust pipeline, and the target working parameter is set as an actual working parameter of the gas water heater.

In addition, in some embodiments, the parameter gear of the smoke exhaust duct can also be determined by acquiring the code according to the setting operation.

For example, in the modulation mode, or in the setup menu, the code of the actual parameter information of the smoke exhaust duct is set, such as the code is HA. The code of the electrode can select different codes through setting operation, thereby selecting different parameters of the smoke exhaust pipeline. For example:

setting the parameter of the smoke exhaust pipeline corresponding to the code 01 as the 1 st grade of [0, 10 ] feet;

setting the parameter of the smoke exhaust pipeline corresponding to the code 02 as [10, 20 ] th grade 2;

setting the parameter of the smoke exhaust pipeline corresponding to the code 03 as [20, 30 ] ft at the 3 rd level;

setting the parameter of the smoke exhaust pipeline corresponding to the code 04 as [30, 40 ] th grade 4;

setting the parameter of the smoke exhaust pipeline corresponding to the code 05 as [40, 50 ] th grade 5;

the parameter of the smoke exhaust duct corresponding to the setting code 06 is 50, 60 feet at the 6 th gear.

For a fully premixed gas water heater or a fully premixed wall-mounted boiler, the rotation speed of a fan is set during working, gas is injected from a nozzle by air flow, primary premixing is carried out in a premixing cavity of a premixer, secondary premixing is carried out in the fan, and the gas enters a combustion chamber for combustion. The parameters are mainly setting of fan rotation speeds including maximum fan rotation speed, minimum fan rotation speed, ignition fan rotation speed and the like.

Thereby improving the use experience of the gas device 1000.

In some embodiments of the present invention, the gas-fired device 1000 further comprises: a dialing device 1006 connected to the processor 1004, the dialing device 1006 including a plurality of dialing switches; the processor 1004, when executing the program or the instructions, realizes acquiring the actual parameter information of the smoke exhaust pipe, including: acquiring the switch state of a dial switch; and determining corresponding actual parameter information in a preset comparison table according to the switch state.

In the embodiment of the present invention, a dial device 1006 is disposed ON the gas device 1000, wherein the dial device 1006 includes a plurality of dial switches, and each dial switch can be switched between two states of "ON (ON)" and "OFF (OFF)". Therefore, the on-off states of the dial switches arranged in sequence can form a binary code with the same number of digits as the dial switches, so that the actual parameter information of different smoke exhaust pipelines can be expressed.

Therefore, after the on-off states of the plurality of dial switches are obtained, the corresponding parameter data of the smoke exhaust pipeline can be inquired in the pre-stored comparison table according to the on-off states, the actual parameter information of the current smoke exhaust pipeline is determined, and the target working parameters are further determined according to the actual parameter information of the smoke exhaust pipeline, so that the gas device 1000 can be ensured to operate at higher combustion efficiency, and the problems of resonant squeaking of the smoke exhaust pipeline, unqualified waste emission and the like are avoided.

Specifically, for example, it is assumed that 4 dial switches are provided on the dial device 1006, and when the dial switches are in the "on" state, the dial switches represent the number 1, and when the dial switches are in the "off" state, the dial switches represent the number zero.
