Intelligent temperature-controlling water supply system of water pump

Abstract

The invention relates to a water pump intelligent temperature-control water supply system which ensures a basically stable water temperature of domestic water, heating water and pipe internal circulating water and saves water resource and heat energy. The system comprises a water pump, a power supply control circuit, a central control unit and a temperature sensor; wherein, an inlet of the water pump is connected with a hot water tank, an outlet of the water pump is connected with an inlet end of a water return pipe, and an outlet end of the water return pipe is connected with the hot water tank; the temperature sensor is used for detecting the temperature on the water return pipe; the central control unit is used for turning on or shutting down the water pump according to the temperaturegap between the temperature measured by the temperature senor and the preset temperature; when the measured temperature is 0.5 to 3 DEG C lower than the preset temperature, the water pump is turned on; and when the measured temperature is 0.5 to 3 DEG C higher than the preset temperature, the water pump is shut down. In addition, in different periods, the central control unit turns on or shuts down the water pump through the power supply control circuit according to the temperature gap between the temperature measured by the temperature sensor and the corresponding different preset temperature.

Description

technical field [0001] The invention relates to a water pump intelligent temperature control water supply system for real-time temperature control of domestic and heating water in indoor water pipelines and circulating water in the pipelines. Background technique [0002] Chinese patent document CN2918804Y discloses an electronic self-control water pump, which includes a motor, a pump body, and an electronic control circuit. A pressure sensor and a temperature sensor are arranged in the pump cavity, and a flow sensor is also arranged in the flow path of the pump. There is also an LCD screen and input buttons on the screen. [0003] Chinese patent document CN1995857Y discloses a feedwater pump control system for controlling the feedwater pressure of a feedwater pump that feeds water to a heat exchanger. Adjust the feedwater pressure setting value of the feedwater pump according to the temperature difference between the water supplied to the heat exchanger and the water retur...

AI Technical Summary

Problems solved by technology

[0006] The disadvantage of the above-mentioned prior art is that the existing indoor water pipelines are all one-way pipelines, that is, the water in the indoor water pipelines can only flow out from the indoor faucet, and cannot realize backflow.

This leads to the cooling of the water entering the indoor water pipe, and the cooled water in the pipe must be released in vain during use, resulting in a waste of water resources

That is to say, the existing technology cannot realize that the water temperature of the tap water is always stable, and the waste of water resources can be avoided.
