Shown in Figure 7, the working principle of the invention can be divided into following three phases:
1. collecting in hot-water line leading portion cold water to water tank
Under off-mode, all regulating valves are closed;First set water temperature and open preparation using switch at this time, hot-water line 65
Hot water water inlet 65a is connect with external hot-water supply device, and water flow enters internal duct along it, and variation in water pressure will trigger water heater
Start to convey hot water.Water flows through the first temperature sensor 65b and obtains temperature data, when entering coolant-temperature gage lower than set temperature, the
One regulating valve 65d is closed, and the second regulating valve 64a is opened, and the leading portion cold water in hot-water line 65 flows into water tank along water tank downcomer
40.When water temperature reaches set temperature, the first regulating valve 65d is opened, and the second regulating valve 64a is closed, the upward water outlet of hot water stream
13。
2. the cold water in water tank recycles
After the water temperature in hot-water line 65 reaches set temperature, third regulating valve 66c is in close state, check-valves 63b
Prevent cold water from blowing back into water tank 40.Suction pump 63a starts to work and regulates and controls water velocity, and the cold water in water tank 40 is along water tank
Upper hose 63 unidirectionally imports cold water pipe 66 by check-valves 63b.After the cold water in water tank 40 is finished, suction pump 63a is closed,
Third regulating valve 66c opens and regulates and controls water flow, and cold water inputs internal duct by the cold water water inlet 66a of cold water pipe 66.
3. automatic water temperature regulation, water
User adjusts water temperature and water yield by control panel, and second temperature sensor 80 measures water in upper water-out mouth 13
Temperature, the first regulating valve 65d, third regulating valve 66c, suction pump 63a adjust hot and cold water jointly, reach preset temperature.
When user uses upper water-out mouth by control panel selection, the 4th regulating valve 61a is opened and the 5th regulating valve 62a is closed
It closes, warm water is flowed out by upper water-out mouth 13;When using lower outlet 43, the 4th regulating valve 61a is closed and the 5th regulating valve 62a
It opens, warm water is flowed out through lower outlet 43.
In addition, in electric energy supply side, it is contemplated that the use environment of the design is bathroom, in order to avoid risk of getting an electric shock, is stored
Battery, regulating valve and water pump select 6V voltage model, meet the IIIth class safe voltage 6V specified in GB380-83 and (refer to people
In swimming pool, sink or pond, human body largely immerses in water, and skin is impregnated with completely, at this moment about 500 Ω of human body internal impedance).
Complete machine electric energy is mainly derived from the hydroelectric generation original part inside machine and kinetic energy (water flow in water pipe) is converted to electricity
It can (battery inside machine) storage.First hydroelectric generator 65c and the second hydroelectric generator 66b utilizes the hydraulic pressure in pipeline
Power generation, electric energy is stored in battery 70, provides electric energy for machine internal circuit element.Under special circumstances, battery can
It individually takes out, reinstalls machine after fully charged using 220v domestic power supply at drying.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
