The embodiment of the invention provides a water heater control method based on a wind pressure sensor, as shown in fig. 1, comprising the following steps:
s100: and acquiring an actual wind pressure value detected by the wind pressure sensor.
The wind pressure sensor can detect the actual wind pressure value in the smoke pipe in real time, and send the detected actual wind pressure value to the controller, and the controller can acquire the actual wind pressure value.
S200: judging whether the actual wind pressure value is larger than or equal to a first preset wind pressure value or not,
this first preset wind pressure value can carry out the wind pressure value with standard tobacco pipe when producing the water heater and mark, and it is the minimum wind pressure value that the water heater can normally work, if be less than this first preset wind pressure value, shows that the water heater can not work with normal mode. The first preset wind pressure value can be stored in the controller, and the controller judges the magnitude relation between the actual wind pressure value and the first preset wind pressure value.
S300: and if the actual wind pressure value is greater than or equal to the first preset wind pressure value, controlling the water heater to work in a normal working mode.
If the actual wind pressure value is larger than or equal to the first preset wind pressure value, the water heater is in a normal working state, and the water heater can work in a normal working mode. The controller can control components such as a proportional valve in a gas pipeline, a water regulating valve for supplying water and the like, and the proportional valve and the water regulating valve are in normal working states in a normal working mode.
S400: if the actual wind pressure value is smaller than the first preset wind pressure value, further judging whether the actual wind pressure value is larger than or equal to a second preset wind pressure value, wherein the second preset wind pressure value is smaller than the first preset wind pressure value;
the actual wind pressure value is smaller than the first preset wind pressure value, which indicates that the water heater cannot work in a normal working mode, and whether the actual wind pressure value is too low or not can be determined by further judging the magnitude relation between the actual wind pressure value and the second preset wind pressure value. The second preset wind pressure value may be set to 80% of the first preset wind pressure value.
S500: and if the actual wind pressure value is greater than or equal to the second preset wind pressure value, controlling the water heater to work in a first lifting mode, and controlling the fan to work in a high-wind-speed gear.
In the first variable-lift mode, the lift number of the water heater is reduced, for example, an original 16L water heater is changed into a 13L water heater, and meanwhile, according to the reduced lift number, a water regulating valve and a proportional valve of the water heater are controlled to change the valve quantity, regulate the water flow and the gas flow, and ensure that the outlet water temperature is stable. Meanwhile, the rotating speed of the fan is increased, and the fan continuously works at a high wind speed.
In some embodiments, as shown in fig. 2, the method for controlling a water heater based on a wind pressure sensor further includes the following steps:
s600: if the actual wind pressure value is smaller than the second preset wind pressure value, whether the actual wind pressure value is larger than or equal to a third preset wind pressure value or not is further judged, and the third preset wind pressure value is smaller than the second preset wind pressure value.
The application range of the water heater working in the first variable-lift mode is limited, and the working mode of the water heater needs to be further changed along with the further reduction of the wind pressure, so that a third preset wind pressure value can be set, and the working mode of the water heater can be further changed according to the magnitude relation between the actual wind pressure value and the third preset wind pressure value. The third preset wind pressure value may be set to 60% of the first preset wind pressure value.

When the wind pressure is further reduced, the water heater needs to work in a second variable-lift mode, in the second variable-lift mode, the lift number of the water heater is further reduced, for example, the water heater which is originally reduced to 13L is changed into a 10L water heater, and meanwhile, according to the reduced lift number, a water regulating valve and a proportional valve of the water heater are controlled to change the valve quantity, adjust the water flow and the gas flow, and ensure the stable water outlet temperature. While the fan will continue to operate at the high wind speed gear.
In some embodiments, as shown in fig. 3, the method for controlling a water heater based on a wind pressure sensor further includes the following steps: s800: and if the actual wind pressure value is smaller than a third preset wind pressure value, controlling the water heater to stop working.
When the actual wind pressure value is further lower than a third preset wind pressure value, the wind pressure value is very low, and the water heater needs to stop working so as to ensure the safety of the water heater.
In some embodiments, the control method of the water heater based on the wind pressure sensor further comprises the following steps: and acquiring a wind pressure repairing instruction of a user, controlling a wind pressure sensor to detect wind pressure in real time to obtain an instant wind pressure value, calculating a difference value between the instant wind pressure value and a preset reference wind pressure value, and modifying a wind pressure starting value and a wind pressure closing value according to the difference value if the difference value is within a preset deviation range.
In the manufacturing process of the water heater, a manufacturer sets a wind pressure starting value and a wind pressure closing value for the water heater, wherein the wind pressure starting value refers to the wind pressure value when the water heater is started to normally work, and the wind pressure closing value refers to the wind pressure value after the water heater stops working. Generally, the wind pressure start value and the wind pressure off value are fixed values by default. However, in the actual use process of the user, because of the difference of the parameters and the installation mode of the smoke tube of each household, the resistance borne by the air inlet pipe and the smoke tube also has difference, if the water heater is controlled to work according to the fixed air pressure starting value and the fixed air pressure closing value, the combustion work of the water heater can be influenced, and even the water heater cannot be used.
The gas heater of this embodiment can set up dedicated "wind pressure and restore" button, and the user can click this "wind pressure and restore" button, and the controller acquires user's wind pressure repair instruction promptly. Or, a mobile device such as a mobile phone used by the user can communicate with the water heater, and the user can send a wind pressure repairing instruction to the controller of the water heater by operating the mobile device. According to the wind pressure repairing instruction, the controller controls the wind pressure sensor to detect the wind pressure value instantly to obtain an instant wind pressure value, and then the controller calculates the difference value between the instant wind pressure value and the preset reference wind pressure value, wherein the instant wind pressure value may be larger than, equal to or smaller than the preset reference wind pressure value, and therefore the difference value may be a positive number, zero or a negative number.
No matter what the actual value of the difference value is, the controller sets a preset deviation range in advance, and only if the difference value is within the preset deviation range, the function of 'wind pressure repair' can be executed. The control will modify the wind pressure on value and the wind pressure off value according to the difference, for example, the set wind pressure on value is-59 Pa, the difference is 3Pa, the two can be added to get the modified wind pressure on value is-56 Pa.
If the difference value exceeds the preset deviation range, the wind pressure deviation is obviously overlarge, the water heater has the problem of wind pressure, and the wind pressure repair can not be carried out according to the difference value.
This embodiment makes the water heater can carry out the self-regulation, lets the water heater modify wind pressure starting value and wind pressure closing value to match actual in service behavior, make the water heater can high-efficient stable work. Meanwhile, the regulation is started manually, so that the condition that the parameters are frequently and repeatedly modified to cause instability of the water heater is prevented.
