Shower system for recovering hot water without cold water and control method thereof

Abstract

The invention discloses a shower system for recovering hot water without cold water and a control method thereof. The shower system comprises a controller, a sprinkler switch, a water heater, a water heater water inlet pipe, a water heater water outlet pipe, a first temperature sensor, a first pump, a first electromagnetic valve, a water tank, a second electromagnetic valve, a ventilation hole, a second temperature sensor, a sprinkler, a tap hot water inlet, a second pump, a connecting pipe, a third temperature sensor, a third pump, a third electromagnetic valve, a water return pipe, a sprinkler water inlet pipe, a sprinkler return pipe, a fourth electromagnetic valve, a fourth pump, a fifth electromagnetic valve, a sixth electromagnetic valve and the like. The shower system can really guarantee no flowing out of the cold water from the sprinkler (11), has no need to worry about users to catch a cold caused by lower water temperature, meanwhile, realizes recovery of afterheat water after use of the hot water, and achieves the effects of energy saving and water saving.

Description

technical field [0001] The invention relates to a shower device and a control method thereof, in particular to a shower system without cold water and hot water recovery and a control method thereof. Background technique [0002] In today's world, people have realized the preciousness of water resources and will adopt various methods to save and recycle water resources. And the water heater that adopts when people showers mainly is divided into gas type and electric heating type at present. No matter what type of water heater it is, there is cold water stored in the pipe connected between the water heater and the shower, which is called "ineffective hot water before use", and it is often drained before taking a bath, especially in winter, the amount of wasted water What's more, if the temperature in the bathroom is too low, the bather will easily catch cold and get sick. Through research on water heaters, we found that the cold water flowing out before using hot water comes...

AI Technical Summary

Problems solved by technology

In fact, the technical solution recorded in this patent document cannot guarantee that there will be no drop of cold water flowing out of the shower, because before the shower starts, there is cold water accumulated in the upper water pipe between the water tank and the shower, and a series of control actions do not Treat the cold water in the upper water pipe between the water tank and the shower. When the solenoid valve is opened, the cold water in the upper water pipe between the water tank and the shower will first appear in the shower, causing inconvenience to the user
