Wall-hanging stove control method, device and equipment and computer readable storage medium

Abstract

The invention belongs to the technical field of water heaters, and discloses a wall-hanging stove control method, device and equipment and a computer readable storage medium. The method comprises the steps that the real-time air pressure value of a draught fan of a wall-hanging stove is monitored; when the real-time air pressure value of the fan is reduced to a first protection air pressure value, the working voltage of the fan is reduced to a preset judgment voltage; acquiring a first actual wind pressure value of the fan at the preset judgment voltage; if the first actual air pressure value is smaller than a preset judgment air pressure value, the current working condition is judged to be a low-voltage working condition; and if the first actual air pressure value is larger than or equal to the preset judgment air pressure value, it is judged that the current working condition is the blockage working condition. And when the actual air pressure value is reduced to the first protection air pressure value, the working voltage of the fan is adjusted to the preset judgment voltage, and the first actual air pressure value corresponding to the preset judgment voltage is compared with the preset judgment air pressure value, so that the low-voltage working condition or the blockage working condition is accurately judged, and misinformation is avoided.

Description

technical field [0001] The present invention relates to the technical field of water heaters, in particular to a control method, device, equipment and computer-readable storage medium for a wall-hung boiler. Background technique [0002] Existing wall-hung boilers are often preset with a protection wind pressure value. When starting up, the actual wind pressure value of the fan must be greater than the protection wind pressure value to a certain extent before it can be started normally. If the actual wind pressure value cannot meet this condition, the wall-hung boiler will be turned off. Shutdown; At the same time, when the exhaust pipe of the wall-hung boiler is blocked, the actual wind pressure value in the Venturi pipe needs to be lower than the shut-off value to be able to shut down and stop the protection before the flue gas exceeds the standard. [0003] During the combustion process, due to the decrease of the gas density passing through the fan, the wind pressure val...
