Intelligent water supply system with hot water supply function

Abstract

The invention discloses an intelligent water supply system with a hot water supply function.The intelligent water supply system comprises a water source, a water pump and a faucet which are sequentially connected through a pipeline.The intelligent water supply system further comprises a flow sensor, a controller, a PWM frequency conversion module and a water heater, wherein the flow sensor is mounted on the portion, between the water pump and the faucet, of the pipeline; the controller is connected with the flow sensor; the control end of the PWM frequency conversion module is connected with the controller, and the output end of the PWM frequency conversion module is electrically connected with the water pump; the controller regulates the pulse width of the PWM frequency conversion module according to a water flow signal acquired by the flow sensor so as to control the rotating speed of the water pump; a water feeding pipe of the water heater is communicated with the portion, between the flow sensor and the faucet, of the pipeline, a heater is arranged in the water heater, and the horizontal height of the heater is smaller than that of the water feeding end of a water discharging pipe of the water heater.The intelligent water supply system enables the water pump to adjust the rotating speed according to the water flow of the faucet, thus, the use efficiency of the water pump can be guaranteed, and the wear speed of the water pump can be reduced; meanwhile, the system is additionally provided with the water heater, and therefore hot water can be supplied to a user.

Description

technical field [0001] The invention relates to the field of intelligent equipment, in particular to an intelligent water supply system with hot water supply. Background technique [0002] Usually, the water supply of the water pump is driven by the motor to drive the water pump and the water turbine to directly energize and pump water, but it needs to be filled with a water tank bucket, and whether to stop pumping is controlled according to the water level in the bucket. Cause the water tank to be full of water to be a hazard, in addition just increase the danger even more if the float water tank will be controlled on the top of the high water tower, and the circuit is complicated, and it is inconvenient to manufacture, install and use. [0003] In order to overcome the above-mentioned difficulties, as the patent document of Chinese Patent No. 200620141929.7 discloses an air constant pressure automatic water supply machine without a tower, the water supply machine adds a co...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an intelligent water supply system with hot water supply, so as to overcome the disadvantage that the power of the water pump cannot be adjusted, so that no matter whether the water supply is small or large, it is pumped at normal power, causing the water pump to wear out too quickly
