Hot water circulation supply control system

Abstract

The invention discloses a hot water circulation supply control system, which comprises a water heater, a water outlet pipeline and a water inlet pipeline, wherein the water outlet pipeline and the water inlet pipeline are respectively connected with the water heater, the tail end of the water outlet pipeline is provided with a circulation pump, the circulation pump is communicated with the water inlet pipeline through a pipeline, meanwhile, an electromagnetic valve, a central control system, a wireless network and user handheld mobile control equipment are also arranged on the water inlet pipeline, the central control system is used for controlling the on-off state of the electromagnetic valve, the wireless network is connected with the central control system, and the user handheld mobile control equipment is connected with the wireless network. The hot water circulation supply control system effectively solves the problems that in the prior art, a certain quantity of cold water needs to be discharged out before hot water is discharged out from the water heater, so the water resource waste is caused, and the waiting is needed; higher practical values are realized.

Description

technical field [0001] The invention relates to a civil hot water supply technology, in particular to a hot water circulation supply control system. Background technique [0002] In addition to busy work, being able to use hot water in time can not only effectively relieve fatigue, but also effectively improve the quality of life, especially for high-income people working in cities, who usually have great work pressure and need to relax frequently to adjust their work rhythm , to ensure work efficiency and quality, and using hot water to wash hands, face or take a bath is a healthy and fast way to relax. [0003] However, there is a seemingly insignificant but extremely influential phenomenon in the hot water supply system in today's society: every time you turn on the tap, the first thing that comes out is cold water, even if it is a high-quality and high-efficiency water heater, it takes at least 10 seconds To release hot water. The main reason for this phenomenon is: on...

Problems solved by technology

[0003] However, there is a seemingly insignificant but extremely influential phenomenon in the hot water supply system in today's society: every time you turn on the tap, the first thing that comes out is cold water, even if it is a high-quality and high-efficiency water heater, it takes at least 10 seconds to release hot water

The main reason for this phenomenon is: on the one hand, it takes a process for the water heater to heat the cold water. The existing water heater controls the switch of the water heater by turning on and off the faucet, but when the faucet is turned on, the water in the water tank of the water heater is still cold water. As a result, the water coming out of the faucet at this time must be cold water; on the other hand, after using hot water last time, some water remains in the outlet pipe between the water heater tank and the faucet and has not been released. When the faucet is turned on next time, The first thing to release must be the cold water that has been cooled in the outlet pipe

When people need to use hot water, the cold water flowing out of the tap not only makes people feel helpless, but also wastes time, and more importantly, wastes water resources, which is not conducive to the national advocacy of water saving and energy saving
