Problems solved by technology

The current zero-cold water heaters usually preheat at the maximum working condition during the preheating stage, that is, the water pump of the water heater works at the maximum speed, and the flow rate of the water pump of the water heater is at the maximum value, resulting in a large noise during the preheating stage. And the pump is in the maximum working condition for a long time, resulting in shortened life of the pump
In addition, if the zero-c...

Abstract

The embodiment of the invention provides a control method and a control device of a water heater, relates to the technical field of household appliances, and aims to reasonably match the flow speed of a water pump of the water heater in a preheating stage, reduce the noise of the water heater in the preheating stage and prolong the service life of the water pump in the water heater while ensuring the preheating effect of the water heater. The control method comprises the steps that the expected preheating time length of the water heater is obtained, wherein the expected preheating time length is used for indicating the time length needed by the water heater to preheat circulating water to reach the expected preheating temperature; according to the expected preheating time length of the water heater and the volume of the circulating water, needing to be preheated, of the water heater, the flow speed of the water pump in the water heater is determined; and the water pump is controlled to work according to the flow speed of the water pump to preheat the circulating water in the water heater.

Description

technical field [0001] The present application relates to the technical field of home appliances, and in particular to a control method and a control device for a water heater. Background technique [0002] Water heaters have become one of the household appliances commonly used in family life. With the gradual improvement of people's quality of life, the functions of water heaters are becoming more and more perfect. [0003] Zero-cold water heaters have become the development trend of the water heater industry because of their instant working characteristics, and are favored by more and more consumers. The current zero-cold water heaters usually preheat at the maximum working condition during the preheating stage, that is, the water pump of the water heater works at the maximum speed, and the flow rate of the water pump of the water heater is at the maximum value, resulting in a relatively loud noise during the preheating stage. And the water pump is in the maximum working...
