Abstract

The utility model relates to a backwater device of a solar water heater, a backwater pipe is arranged between a water inlet pipe and a water outlet pipe of a water tank of the water heater, a temperature-controlled electric water pump is arranged on the backwater pipe, and the temperature-controlled electric water pump consists of a thermistor, an electromagnetic relay and an electric water pump. Due to the adoption of the structure, when the temperature of water in the water outlet pipe of the water heater is lower than the temperature set by the thermistor, the electromagnetic relay automatically starts the electric water pump, and warm water is sent back into the water tank of the water heater and then heated, thereby achieving the purposes of water conservation and energy conservation.

Description

Water returning device of solar energy water heater
Technical field
The utility model relates to a kind of improvement of solar water heater, particularly a kind of water returning device of solar energy water heater.
Background technology
When now solar water heater used, outlet pipe can be emitted a large amount of warm water, and usually by slatterning in vain, neither water saving is not energy-conservation again for such warm water.
Summary of the invention
The purpose of this utility model is exactly that a kind of water returning device of solar energy water heater of saving water and energy will be provided.
The purpose of this utility model is achieved in that a kind of water returning device of solar energy water heater, between the water inlet pipe of water-heater water tank and outlet pipe, return pipe is set, be provided with the temperature-control electric water pumper on return pipe, the temperature-control electric water pumper is made up of thermistor, electromagnetic relay and electric pump.
Owing to adopt said structure, so when the water temperature in the water heater outlet was lower than the thermistor established temperature, electromagnetic relay started electric pump automatically, send warm water back in water-heater water tank heating again, reach the purpose of saving water and energy.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 1 double as Figure of abstract.
Among the figure: 1, water-heater water tank, 2, water inlet pipe, 3, outlet pipe, 4, return pipe, 5, the temperature-control electric water pumper.
The specific embodiment
As shown in Figure 1, a kind of water returning device of solar energy water heater, between the water inlet pipe 2 of water-heater water tank 1 and outlet pipe 3 return pipe 4 is set, is provided with temperature-control electric water pumper 5 on return pipe 4, temperature-control electric water pumper 5 is made up of thermistor, electromagnetic relay and electric pump.
During use, when the water temperature in the water heater outlet 3 is lower than on the return pipe 4 in the temperature-control electric water pumper 5 the thermistor established temperature, electromagnetic relay starts electric pump automatically, send warm water back in the water-heater water tank 1 heating again through return pipe 4, water inlet pipe 2, when water temperature reaches the thermistor established temperature, electromagnetic relay stops electric pump work automatically, and shows or broadcast music and tell the user.
