Water heater fan control method, device and equipment and water heater

Abstract

The invention relates to a water heater fan control method, device and equipment and a water heater. The method comprises the steps that after the real-time rotating speed of a fan of the water heaterin the running process is obtained, the variable quantity of the real-time rotating speed within a preset time period is calculated, and when it is judged that the real-time rotating speed is decreased according to the variable quantity, and the input voltage transmitted to the fan is increased till the real-time rotating speed meets the preset normal running condition. In the normal combustion process of the water heater, when a smoke outlet is blocked due to external factors or strong wind directly blows the smoke outlet, the wind pressure value in a smoke pipe can be changed, the wind resistance is increased, the rotating speed of the fan is decreased under the condition that the input voltage is not changed, the input voltage transmitted to the fan is increased at the moment, and therotating speed of the fan can be increased by increasing the input voltage. The increment of wind resistance is balanced by the increased rotating speed of the fan, so that a hearth maintains a stablecombustion working condition, a series of problems caused by combustion imbalance are avoided, and the thus the using reliability of the water heater is improved.

Description

technical field [0001] The present application relates to the technical field of household appliances, in particular to a water heater fan control method, device, equipment and water heater. Background technique [0002] A water heater is a widely used household appliance. It uses various physical principles to increase the temperature of cold water and turn it into hot water within a certain period of time for users to use, which improves the convenience of people's daily life. [0003] The fan is the core component of the water heater. In a traditional water heater, the speed of the fan is generally maintained at a fixed speed, and does not change due to changes in power and external conditions. This causes changes in the external environment, such as strong winds during use. When the fan speed remains unchanged, the negative pressure in the furnace will decrease, which will cause an abnormal ratio of air and oxygen in the combustion chamber, resulting in a series of probl...
