Abstract

A cold water recycling device for a bathroom comprises a hot water tank, a tap water inlet pipe used for conveying cold water to the hot water tank and a hot water outlet pipe used for outputting hot water from the hot water tank. A return pipe used for enabling cold water in the hot water outlet pipe to flow back to the tap water inlet pipe is arranged between the tap water inlet pipe and the hot water outlet pipe, a temperature sensor I used for detecting the temperature of water in the hot water outlet pipe is arranged on the inner wall of the hot water outlet pipe in an embedded mode, the temperature sensor I transmits detected temperature information to a microprocessor, the microprocessor controls opening and closing of a switch arranged on the hot water outlet pipe, opening and closing of a solenoid valve and switching-on and switching-off of a water pump according to the received temperature information, the solenoid valve and the water pump are arranged on the return pipe, and therefore backflow of the cold water in the hot water outlet pipe is achieved. In the cold water recycling device for the bathroom, the cold water in the hot water outlet pipe enters the tap water inlet pipe through the return pipe so as to flow into the hot water tank to be heated again, so that water resources are effectively saved; due to the arrangement of the water pump, the cold water can arrive at the hot water tank rapidly, and the hot water waiting time is shortened.

At present, people have a bath and conventionally adopt shower, and in having a bath, the hot water in the hot-water line of discontinuous use hot water can cool off very soon, while reusing hot water, must discharge cold water and could use hot water, at present a lot of people's way is that the cold water in hot-water line is directly entered to sewer by tap.So just waste a lot of water resources.
Utility model content
The utility model is in order to reduce the problem that is full of the water resource waste that cold water brings before hot water in hot-water line because using, provide a kind of can Quick supplying hot water and prevent a kind of cold water Recycling device for bathroom of water resource waste.
The technical scheme that the utility model adopts is: a kind of cold water Recycling device for bathroom, comprise boiler, to carrying the running water water inlet pipe of cold water in boiler and from exporting the hot water outlet pipe of hot water in boiler, between described running water water inlet pipe and hot water outlet pipe, be provided with the cold water making in hot water outlet pipe and be back to the return duct of running water water inlet pipe, be embedded with the temperature sensor I for detection of water temperature in its pipe at described hot water outlet pipe's inwall, the temperature information detecting is passed to microprocessor by temperature sensor I, microprocessor is arranged on the switch on hot water outlet pipe according to the temperature information control that receives and is arranged on the keying of magnetic valve and water pump on return duct, thereby realize the backflow of cold water in hot water outlet pipe.
In described boiler, be provided with level sensor.
Described hot water outlet pipe outside is provided with a temperature indicator, for showing the temperature of water in hot water outlet pipe.
Described hot water outlet pipe's end is connected with shower nozzle, and the below spray wall of this shower nozzle is provided with temperature sensor II.
Described boiler, with electric heater, is equipped with water intake ball valve on boiler, running water water inlet pipe is equipped with check valve to the pipeline between water intake ball valve, and the outlet of return duct is located between water intake ball valve and check valve.
Described hot water tank top is provided with gap.
The beneficial effects of the utility model: the cold water in the utility model in hot water outlet pipe all circulates to enter to reach in water supply pipe and then flow into boiler by return duct and again heats, effectively save water resource, arranging of water pump can be that cold water arrives water tank fast, shortened the time of waiting for hot water.
Brief description of the drawings
