Zero-cold-water water heater system, control method thereof and computer readable storage medium

Abstract

The invention relates to the field of electrical appliances, in particular to a zero-cold-water water heater system, a control method thereof and a computer readable storage medium. Each water using unit of the zero-cold-water water heater system comprises a branch water inlet pipe communicating with a water outlet of a water heater, a branch water return pipe communicating with a water inlet of acirculating water pump, a bypass water pipe, a water using site, a first valve, a temperature sensor and an electromagnetic valve, wherein both the bypass water pipe and the water using site communicate between the branch water inlet pipe and the branch water return pipe, the first valve is arranged at the water using site, and the temperature sensor and the electromagnetic valve are arranged onthe bypass water pipe; and a controller is electrically connected with the water heater, the circulating water pump, the temperature sensors and the electromagnetic valves, and the controller is usedfor starting the water heater and the circulating water pump and opening the electromagnetic valves when temperature information transmitted by the temperature sensors is less than or equal to a firsttemperature threshold, and delaying a time threshold to stop the water heater and the circulating water pump and close the electromagnetic valves when the temperature information transmitted by the temperature sensors is greater than or equal to a second temperature threshold, wherein the second temperature threshold is greater than the first temperature threshold.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a zero-cold water heater system, a control method thereof, and a computer-readable storage medium. Background technique [0002] As people's pursuit of water temperature is getting higher and higher, the zero-cold water heater system has become the common pursuit of most users; It is a technology to release the heated hot water to avoid a large amount of cold water flowing out when the user turns on the water heater. [0003] At present, the existing zero-cold water heaters mainly open or close the electromagnetic valve at each water point through a wireless remote control device, which requires artificial preheating before using water. To a certain extent, there is still a need to wait for hot water use, and For hot water points that are far away from the water heater, there is also the problem of poor water temperature stability, resulting in poor performance and reduced u...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to wait for the hot water to be used due to the need to artificially open the solenoid valve at the water point of the above-mentioned zero cold water water heater, and for the hot water point far away from the water heater, there is also the problem of poor water temperature stability, Provided are a zero-cold water heater system, its control method, and a computer-readable storage medium
