Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.
The embodiment of the application provides a control method of a gas water heater, the gas water heater and a computer readable storage medium. Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart of a control method of a gas water heater according to an embodiment of the present application, where the method is applied to the gas water heater to adjust the combustion state of the gas water heater in real time, reduce harmful gas and improve the gas utilization rate, so that the gas water heater works more efficiently.
For ease of understanding, the following embodiments will be described in detail as applied to a gas water heater.
As shown in fig. 1, the control method of the gas water heater may include steps S101 to S102.
Step S101, acquiring the current flame height of the gas water heater.
Illustratively, when the gas water heater works, flame is generated by igniting inside a burner in the gas water heater, and the flame height in the burner is obtained.
The flame in the burner has a certain height after the gas water heater is ignited, but the flame is changed in height due to the restriction of environmental factors, so that the current combustion state of the gas water heater can be determined based on the change of the flame height.
By way of example, the environmental factors may be whether the atmosphere in the region is lean, whether the gas flow rate is too high, etc.
For example, an environment with too low an airflow rate and too low an airflow rate may increase flame height, while an environment with too high an airflow rate and too high an airflow rate may decrease flame height.
For example, in some areas with higher altitudes, the air is too thin, and if the air intake standard of the complete combustion of the gas water heater with lower altitudes is based on the air intake standard, the gas water heater in the area with higher altitudes cannot be completely combusted; it can be appreciated that, based on the intake standards of the higher altitude areas, the gas water heater in the lower altitude areas may be too air-filled and may not reach the optimal combustion state.
Illustratively, the current combustion state of the gas water heater is determined by acquiring the flame height, and the gas water heater is adjusted to achieve the optimal combustion state of the gas water heater.
In some embodiments, the obtaining the current flame height of the gas water heater comprises: and determining the flame height according to the detection results of a plurality of flame probes, wherein the flame probes are arranged at preset heights in the burner of the gas water heater.
As shown in fig. 2a, 2b and 2c, fig. 2a, 2b and 2c are front view, left view and top view of a schematic structure of a flame probe according to an embodiment of the present application.
For example, the flame height can be detected by a flame probe, and the flame height is determined based on the detection result.
Illustratively, a number of flame probes are installed at preset heights in the burner of the water heater to detect different flame heights.
For example, the preset height may be a flame height in an optimal combustion state of each target power.
For example, flame probes of different heights can detect the flame height in the optimal combustion state of different powers to improve the detection accuracy.
For example, when the flame probe detects a flame, a voltage may be measured at the lead end of the flame probe, and the flame height may be determined based on the voltage information.
For example, the corresponding flame height in the optimal combustion state of the target power of the gas water heater can be set, and the gas water heater can be regarded as being in the optimal combustion state of the current power when the current flame height is detected by the flame probe corresponding to the flame height in the optimal combustion state.
The flame height is determined according to the detection results of the flame probes, and the current combustion state of the gas water heater can be detected in real time, so that the gas water heater is adjusted, and the gas water heater achieves the optimal combustion state.
Step S102, adjusting the valve opening of the gas water heater and/or adjusting the fan rotating speed of the gas water heater according to the flame height.
Illustratively, the current combustion state is determined according to the flame height, so as to adjust the valve opening of the gas water heater and/or adjust the fan rotating speed of the gas water heater.
The valve opening of the gas water heater and/or the fan rotating speed of the gas water heater are/is adjusted to control the gas water heater to adapt to the environmental factors, so that the optimal combustion state is achieved.
In some embodiments, the adjusting the valve opening of the gas water heater and/or adjusting the fan rotation speed of the gas water heater according to the flame height includes: and adjusting the valve opening of the gas water heater and/or adjusting the fan rotating speed of the gas water heater according to the current flame height and the target flame height, wherein the target flame height is the flame height corresponding to the target power.
For example, the target power of the gas water heater may be determined according to a user setting, that is, when the user sets the water temperature of the water, the target power corresponding to the water temperature may be determined, so that the gas water heater heats the water to the water temperature set by the user.
For example, the target power and the target flame height are in one-to-one correspondence, and the target flame heights of the corresponding optimal combustion states are different under different powers of the gas water heater.
The target flame height is positively correlated with the target power, for example, the higher the water temperature set by the user, such as the water temperature set by the user is 80 degrees celsius and the water temperature set by 50 degrees celsius, the higher the power of the gas water heater set at 80 degrees celsius than the power of the gas water heater set at 50 degrees celsius by the facility, and it is understood that the target flame height set at 80 degrees celsius is also higher than the target flame height set at 50 degrees celsius.
Illustratively, whether the gas water heater is in an optimal combustion state is determined according to the current flame height and the target flame height, and the air valve opening and/or the fan rotating speed are adjusted according to the determined result.
In some embodiments, the adjusting the valve opening of the gas water heater and/or adjusting the fan speed of the gas water heater according to the current flame height and the target flame height includes:
and if the current flame height is higher than the target flame height, increasing the opening of an air valve of the gas water heater and/or increasing the rotating speed of a fan of the gas water heater.
Illustratively, the current flame height is higher than the target flame height, demonstrating insufficient air, and increasing the current flame height requires increasing the air entering the burner in the gas water heater.
Illustratively, the air entering the burner in the gas water heater is increased by increasing the air valve opening of the gas water heater and/or increasing the fan speed of the gas water heater.
In other embodiments, the adjusting the valve opening of the gas water heater and/or adjusting the fan speed of the gas water heater according to the current flame height and the target flame height includes: and if the current flame height is lower than the target flame height, reducing the opening of an air valve of the gas water heater and/or reducing the rotating speed of a fan of the gas water heater.
Illustratively, the current flame height is lower than the target flame height, demonstrating an excess of air, causing the current flame height to decrease, requiring a reduction in air entering the burner in the gas water heater.
Illustratively, air entering a burner in a gas water heater is reduced by reducing the air valve opening of the gas water heater and/or reducing the fan speed of the gas water heater.
Acquiring the current flame height of the gas water heater; and adjusting the valve opening of the gas water heater and/or adjusting the rotating speed of a fan of the gas water heater according to the flame height. The combustion state of the gas water heater can be controlled to be optimal according to different environmental conditions, the efficiency and the gas utilization rate of the gas water heater are improved, and the generation of harmful gas is reduced.
In some embodiments, as shown in FIG. 3, the method further comprises step S201-step S203
Step S201, determining a target air flow rate corresponding to the target power.
For example, each power of the gas water heater has a one-to-one corresponding target air flow rate to heat and/or preserve different target water temperatures.
The target air flow is, for example, an air flow that can bring the gas water heater to an optimal combustion state at a target power.
For example, under different powers, the gas supply amounts of the gas inside the gas water heater are different, and different air supply amounts are needed, so that the gas and the air are fully reacted and combusted, and the gas water heater achieves the optimal combustion state.
For example, if the gas supply amount in the gas water heater is far higher than the air supply amount, the gas utilization rate is reduced, the heating efficiency of the gas water heater is reduced, and harmful gas may be generated; if the gas supply amount is much lower than the air supply amount, the heating efficiency of the water heater is also lowered.
Step S202, obtaining the current air flow.
For example, the current air flow of the gas water heater may be determined based on the current flame height.
The current air flow is, for example, the amount of air actually entering the burner of the gas water heater at the current power of the gas water heater.
For example, the current air flow determines the current flame height, if the current air flow is too small to enable the fuel gas to react and burn fully, the flame height will increase.
For example, the flame height may be determined according to the detection result of the flame probe to determine the current air flow rate of the gas water heater through the flame height.
For example, an air flow detecting device may be further provided at the air inlet to detect the current air flow.
The flow rate of the air may be changed by changing the opening of the gas valve or the air valve, or by controlling the rotation speed of the blower fan, for example.
And step 203, adjusting the valve opening of the gas water heater and/or the fan rotating speed of the gas water heater according to the current air flow and the target air flow.
Illustratively, the valve opening of the gas water heater and/or the fan speed of the gas water heater are/is adjusted according to the current air flow and the target air flow, so that the actual air flow entering the gas water heater is adjusted to the target air flow.
By way of example, the air flow entering the gas water heater is the target air flow, so that the gas water heater can reach an optimal combustion state, the efficiency is improved, and the generation of harmful gases is reduced.
Illustratively, the air valve opening adjustment direction and/or the gas valve opening adjustment direction of the gas water heater is determined according to the target air flow rate and the current air flow rate.
The valve opening of the gas water heater can be adjusted to adjust the air inlet amount of the gas water heater to the optimal ratio of gas to air, so that the gas water heater reaches the optimal combustion state.
In some embodiments, the determining a target air flow corresponding to the target power includes: the target air flow is positively correlated with the target power.
Illustratively, the higher the target power, the more fuel gas is fed into the burner in the gas water heater, and the more air is needed to burn fully.
In some embodiments, the adjusting the valve opening of the gas water heater and/or the fan speed of the gas water heater according to the current air flow and the target air flow includes: and if the current air flow is smaller than the target air flow, increasing the opening degree of an air valve of the gas water heater and/or increasing the rotating speed of a fan of the gas water heater.
Illustratively, the gas water heater may not achieve the optimal combustion state because the ratio of air and gas in the burner of the gas water heater is not uniform, and the air flow rate may be adjusted to optimize the ratio of air and gas in the burner.
The current combustion state is that the fuel gas is insufficiently combusted, the flame height is increased, the target air flow rate determined according to the target power is 30L/min, the acquired current air flow rate is 10L/min, the target air flow rate is higher than the current air flow rate, the air flow rate needs to be increased, and the air valve of the fuel gas water heater is adjusted to be increased so that the inlet air flow rate is increased.
It will be appreciated that the fan of the gas water heater may also be increased to increase the air flow rate into the burner.
In other embodiments, the adjusting the valve opening of the gas water heater and/or the fan speed of the gas water heater according to the current air flow and the target air flow includes: and if the current air flow is larger than the target air flow, reducing the opening degree of an air valve of the gas water heater and/or reducing the rotating speed of a fan of the gas water heater.
For example, the current combustion state is air excess, the flame height is reduced, the target air flow determined according to the target power is 30L/min, the acquired current air flow is 50L/min, the target air flow is less than the current air flow, the air flow needs to be reduced, and the air valve of the gas water heater is adjusted to be reduced, so that the entering air flow is reduced.
It will be appreciated that the fan speed of the gas water heater may also be reduced to reduce the amount of air blown into the burner.
By adjusting the opening of the air valve of the gas water heater and/or the rotating speed of the fan of the gas water heater, the air and gas ratio of the burner in the gas water heater is adjusted, so that the gas water heater achieves the optimal combustion state, the efficiency is improved, the gas utilization rate is improved, and the generation of harmful gas is reduced.
Fig. 4 is a schematic flow chart of another control method of a gas water heater according to an embodiment of the present application.
In some embodiments, as shown in fig. 4, the method further comprises steps S301 to S302.
Step S301, determining the valve opening degree of the gas water heater during ignition according to a preset flow relation curve, wherein the flow relation curve comprises an air flow curve and a gas flow curve.
Illustratively, when the gas water heater is ignited, the opening of the valve is generally determined according to pre-stored data to determine the air and gas entering the burner in the gas water heater.
For example, a preset flow relation curve may be pre-stored in the gas water heater, so that the gas water heater determines the valve opening at the time of ignition according to the flow relation curve, so as to determine the air flow and the gas flow at the time of ignition.
The preset flow relation curve is typically data measured in a laboratory by each manufacturer of the gas water heater, and the data is fitted, and the preset flow relation curve cannot adapt to different specific environmental conditions of each region.
For example, when firing, gas water heaters are mostly able to determine the air and gas entering the burner only from a preset flow profile.
As shown in fig. 5, fig. 5 is a schematic flow relation diagram of a control method of a gas water heater according to an embodiment of the present application.
For example, as shown in fig. 5, a preset flow relation curve is stored in the gas water heater, and when the gas water heater ignites, air and gas are controlled to enter the burner according to the air flow and the gas flow corresponding to the ignition value (dH point in the figure) in the flow relation curve so as to perform an ignition operation.
Step S302, the flow relation curve is adjusted according to the flame height, so that the valve opening is determined according to the adjusted flow relation curve when the gas water heater ignites next time.
Illustratively, the flow rate relation curve is readjusted according to the flame height to adjust the air flow rate and the gas flow rate corresponding to the ignition value, so that the valve opening is determined according to the adjusted flow rate relation curve when the gas water heater ignites next time, and the air and the gas entering the combustor are determined.
For example, the air flow and the gas flow corresponding to the ignition value may be adjusted according to the flame height, and the corresponding air flow and gas flow may be adjusted according to specific environmental parameters.
For example, in some areas, the air flow curve is re-fitted to determine the air flow required for the ignition value by calculating the relation between the target air flow corresponding to the target power and the air flow curve according to the flame height.
For example, in a region with a high altitude, a high air flow is required, the air content in the burner is insufficient due to the opening degree of the air flow curve control valve in the preset relation flow curve, the combustion is insufficient, the air flow corresponding to each power in the preset air flow curve is redetermined according to the flame height during working, the air flow curve is redefined, the air flow corresponding to the ignition value is redetermined, and the gas water heater is enabled to control the air flow according to the adjusted air flow curve during the next ignition.
For example, the air flow rate at ignition may be redetermined based on the flame height over a preset period of time to redetermine the air flow rate profile.
For example, the preset time may be a time from when ignition is performed to after ignition, such as a period from when ignition starts to when the timing ends within 2 minutes. It can be appreciated that the preset time can be preset in the gas water heater or set according to a user.
For example, the ratio of air to gas at the time of ignition can be determined according to the target air flow, and the air flow curve and the gas flow curve can be adjusted at the same time, so that the air flow and the gas flow are controlled according to the adjusted gas flow curve to perform ignition operation when the gas water heater ignites next time.
