Abstract

The invention relates to a water return device control method and device. The control method comprises the steps of acquiring the work period duration value of a water return device, acquiring the work duration value of the water return device after a water heater is started and turning off the water return device when the work duration value is greater than preset multiples of the work period duration value. According to the scheme, the water return device is turned off by acquiring the relation between the work period duration value of the water return device and the current work duration value of the water return device after the water heater is started; resource waste and excessive operation of the water return device due to failures of the water heater are avoided; accordingly, the product quality and service life of the water return device are guaranteed; the sensitivity of turn-off operation of the water return device can be reduced by setting the preset multiples in comparisonto prevent the water return device from being turned off mistakenly during normal operation.

Description

technical field [0001] The invention relates to the technical field of electric appliance control, in particular to a control method and device for a water return device. Background technique [0002] Intelligent automatic hot water systems are more and more widely used in industrial and civil fields, especially in mid-to-high-end smart homes, where the automatic hot water function is essential. Throughout the year, especially in winter, the water system can maintain a certain water temperature, so that users can use hot water directly when turning on the water supply equipment, and there is no need to discharge part of the cold water before hot water comes out, which not only reflects a comfortable home environment, And save water resources. As an important component of the intelligent automatic hot water system, the water return device's quality and service life are directly related to whether the entire intelligent automatic hot water system can work normally.
