The invention provides an intelligent water return control method, a controller and a control system. The method comprises the steps of acquiring a preset water utilization period and a preset water return mode corresponding to the preset water utilization period; controlling a circulating water pump connected with a water heater to operate in the preset water utilization period according to the preset water return mode corresponding to the preset water utilization period; and if a turning-on signal of a water flow switch is detected in the preset water utilization period, turning off the circulating water pump. According to the intelligent water return control method, convenience of hot water utilization is greatly improved, waste of water resource can be reduced, unnecessary pipeline circulation is reduced, heat waste of hot water is reduced, the turning-on time of the water heater due to pipeline circulation is decreased, and expense of a user due to hot water is reduced as well.
Description
technical field [0001] The invention relates to the technical field of water heater backwater control, in particular to an intelligent backwater control method, controller and control system. Background technique [0002] For domestic water heaters, the hot water pipe network installed and used in general households is relatively long. If the pipe network circulation is not carried out, the hot water can only be produced after the cold water in the entire hot water pipe network has been drained when the water is first started. This not only affects the comfort in use, but also wastes water resources. [0003] At present, the backwater control methods of the water return generally include the following types: 1. Manual water return: before the user uses water, the pipe network cycle is realized through the manual button; 2. Water flow detection backwater: when the water flow switch detects that the user has hot water , to automatically start the pipe network cycle; 3. Fixed...
