Description
Technical field
The invention belongs to electronic technology field, is specifically related to a kind of discrete type water recovery apparatus based on human testing, control
System and its control method processed.
Background technology
Social progress and economic development bring the improvement of people's living standards, and all kinds of water heaters enter huge numbers of families,
Provided conveniently using hot water for people's bathing etc..But water heater installation part and the EXIT POINT such as bathroom, washing room are distant,
When user opens hot water tap, delivery port first will rack up the water cooled down in the EXIT POINT to water heater hot-water pipeline,
Need just have hot water after waiting even more than ten minutes a few minutes.This time for just wasting the water resource of preciousness and waiting, hot water
Using extremely inconvenient.In order to solve the above problems, there is an urgent need to the continuous invented techniques of people, new technology, new equipment.City at present
Prior art can be divided into water return pipeline and the class of water recovery apparatus two without water return pipeline on field.First, have water return pipeline, such as
Patent No. CN201220099270.9 technical scheme, a water pipe is exactly taken back again to water heater from the most distal section of hot-water line
Lower section, this water pipe returned is exactly the return pipe that we often say.Typically check-valves can be arranged on return pipe and cold water pipe
Junction, when return water system works, the water supply in cold water pipes is exactly mainly to be provided by return pipe, is like this
If making the return water system working time slightly longer, gone to without the hot water also feared in hot water pipeline in cold water pipes,
So hand basin there cold water when will not also come out hot water.But significantly lacked with the presence of the return water system of return pipe
Point：1st, installation return pipe will increase substantial amounts of pipeline material；2nd, it is more complicated that plumbing works are installed back；3rd, it is holding hot water pipeline
Interior hot water often exists, otherwise the cold water in hot-water line is pumped to water heater heating by open close return pipe of crossing, and energy consumption is larger；4th, take
With larger, it is difficult to promoted the use of in popular family.Second, the return water system of no return pipe such as Patent No.
200620110153.2 technical scheme, its advantage is：1st, a large amount of backwater tube materials are saved；2nd, save and install back plumbing works expense
With with man-hour；3rd, it is easy to promote the use of in popular family.But without return pipe return water system the shortcomings that it is as follows：1st, ordinary circumstance
Under, all it is the connection for check-valves being arranged on hot-water line and cold water pipe below water heater distalmost end hand basin during installation
Place, like this if machine somewhat longevity of service a little will result in, we are using distalmost end hand basin cold water
When, it can also release some hot water.2nd, the water recovery apparatus consumption energy is started repeatedly.3rd, wait the time of hot water longer.4、
The backwater for being connected to the hot and cold water branch line in the main water route of backwater is not easy that (according to relevant theoretical, cooling water is difficult to lead in branch line hot-water line
Cross main line backwater flow velocity and take back water heater).
Several control return water modes and weak point at present：No matter water demand the 1st, is whether there is, it is continuous according to desired temperature
The heating of backwater repeatedly, largely certainly will waste many energy without periods of hot water.2nd, tap is opened with existing during hot water
Open several seconds and shut again so that water flow fluctuation switching signal starts water recovery apparatus and started in pipeline, then waits a few minutes or even more than ten
Just there is hot water minute.3rd, hand-held remote controller is configured, presses pre- hot key on a remote control, opens water recovery apparatus, waits a period of time again
Go to use hot water.4th, water recovery apparatus run time section preheating backwater, such as early, middle and late three period plug and plays heat are pre-set
Water, but cannot ensure in other times to timely use hot water, control mode is more stiff.
