Control method and control device for zero-cold-water gas water heater and processor

Abstract

The embodiment of the invention provides a control method and control device for a zero-cold-water gas water heater, a processor, the zero-cold-water gas water heater and a storage medium, and belongsto the field of electric appliances. According to the control method for the zero-cold-water gas water heater, the zero-cold-water gas water heater comprises a circulating water pump and a gas proportional valve, and the control method comprises the steps that water flow on a pipeline of the zero-cold-water gas water heater is obtained; starting of the circulating water pump is determined according to the water flow; under the condition that it is determined that the water flow reaches preset water flow, required load is determined according to the water flow; and the opening degree of the gas proportional valve is controlled based on an active disturbance rejection control algorithm according to the required load. By the adoption of the scheme, the constant temperature of the zero-cold-water gas water heater can be improved.

Description

technical field [0001] The invention relates to the field of electric appliances, in particular to a control method, a control device and a processor for a zero-cooled water gas water heater. Background technique [0002] Zero-cold water gas water heaters have become a trend in the water heater industry and are increasingly favored by consumers because they can realize instant hot water. The main principle is: when the preheating function is started, the built-in circulation pump of the gas water heater runs to drive the water circulation of the external hot water pipe and return pipe to realize preheating. When the return water temperature (that is, the outlet water temperature) reaches the programmed preheating temperature After that, it will automatically turn off the engine and turn off the pump to exit the preheating mode. However, the existing zero-cold water gas water heaters usually use PID and other control algorithms to control the outlet water temperature to main...
