Problems solved by technology

Due to the lengthy response transmission link in the whole adjustment process, and each link takes a certain amount of time, it will cause hysteresis in the wind pressure response control process
In addition, the existing technology judges whether the air volume is sufficient by calculating elements such as fan power or current, and there are differences between the two to a certain extent, coupled with the influence of calculation and calibration errors and hysteresis responses in various links in the middle, resulting in errors in the existing technology bigger, less precise
[0005] In summary, the wind pressure control method in the prior art has problems such as control response hysteresis and low accuracy.

Abstract

The embodiment of the invention discloses a wind pressure control method, device and equipment and a storage medium. The method comprises the steps of obtaining current wind pressure strength in a smoke pipe; detecting whether the current wind pressure strength is within the range of rated wind pressure strength; and if it is determined that the current wind pressure strength is not within the range of the rated wind pressure strength, adjusting the current rotating speed of a fan, and returning to execute the operation of obtaining the current wind pressure strength in the smoke pipe so as todynamically control the wind pressure. According to the technical scheme, the wind pressure real-time adjusting is achieved, the control response speed is improved, and the wind pressure compensationprecision is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of water heater control, in particular to a wind pressure control method and device, a gas water heater and a storage medium. Background technique [0002] When the gas water heater is in a windy weather or the exhaust port of the flue is blocked, it is often difficult to ignite, ignite and deflagrate during the ignition process; in the normal combustion process, the combustion is inhibited and incomplete combustion occurs, resulting in excessive smoke emissions. Even the flame goes out after burning for a while. This is because when the outdoor wind pressure is too high, the difference between the wind pressure generated by the fan inside the flue pipe and the outside wind pressure becomes smaller, and the exhaust of the fan will be suppressed, resulting in insufficient air volume for combustion. [0003] In the prior art, wind pressure control is mainly realized by calculating an...
