It sets 4 entirety not to be destroyed, also ensures that other positions of purifier are not destroyed, when the later period is replaced, it is only necessary to replacement storage
Water portion 41 saves the maintenance cost in later period.
The application also proposes to protect a kind of purifier, such as water purifier, which includes above-mentioned water process system
System, to protect purifier preferably normal use.
Refering to what is shown in Fig. 1, the application also proposes to protect a kind of control method of water treatment system, which is upper
That states is provided with the water treatment system of circulation branch road 8, has pure water circulating purification mode.
Refering to what is shown in Fig. 1, when the water treatment system runs pure water circulating purification mode, if first level sensing is first
The liquid level that part 42 detects is not up to the safety levels, then controls the raw water water inlet switch 11 and the second switch unit
512 close, and the first switch unit 511 is opened, so that water flow is between water storage device 4, circulation branch road 8 and filter device 21
It circulates, on the one hand can carry out circulating purification to the water in the water treatment system, further increase clean-up effect, on the other hand
Certain flushing action can be played to the RO membrane filter in filter device 21, the dirt for slowing down RO membrane filter is stifled, extends filter device
21 service life.Preferably, the faucet 31 when running pure water circulating purification mode, on control device control water intaking flow path 3
It closes, that is, when user's water intaking, preferably the water treatment system is without pure water circulating purification mode, to guarantee user's water intaking
The speed and flow of water flow.In addition, preferably stabilized pressure pump is in starting state, when running pure water circulating purification mode to ensure
Hydraulic pressure in the water treatment system guarantees the normal operation of pure water circulating purification mode.
Refering to what is shown in Fig. 1, being controlled if the liquid level of the first level sensing element 42 detection reaches the safety levels
The raw water water inlet switch 11 is closed, and the first switch unit 511 is opened, the second switch unit 512 fully opens, this
When, water a part in the water treatment system is flowed out by waste discharge branch 6, and another part is carried out net again by filter device 21
Change, so that the liquid level in water storage device 4 be made to reduce, guarantees that water storage device 4 is not swarmed in.
Refering to what is shown in Fig. 1, draw water pump startup, at this time water inlet electricity it should be noted that opening faucet 31 when user fetches water
Magnet valve, stabilized pressure pump are opened, and wastewater valve is in throttle, i.e., are at this time aqueous mode processed and water taking mode；When the second liquid level is examined
When survey element 43 detects that the liquid level in the water storage part 41 reaches stopping aqueous position, stop water processed in the water treatment system
Meanwhile the prompting interface display water on faucet 31 is full, stops water processed to inform that liquid level of the user at this time in water storage device 4 has reached
Liquid level reminds user to fetch water in time, water storage device 4 is avoided to be swarmed in；User is not in the case where fetching water, pure water circulating purification mould
The runing time of formula is 1s-30min, to save power supply.More preferably, when the liquid level in water storage device 4 reaches safety levels,
The water treatment system persistently carries out pure water circulating purification mode, preferably to protect water storage device 4 not swarmed in.It needs to illustrate
Be stop aqueous position processed when the liquid level in water storage device 4 has reached, but not up to safety levels when, water treatment system fortune
When row pure water circulating purification mode, wastewater valve is preferably in throttle, wastes to avoid the transition of water resource, and when water storage fills
When setting the liquid level in 4 and reaching safety levels, when which runs pure water circulating purification mode, preferably wastewater valve has been in
Full opening state avoids being swarmed in ensure that the water treatment system is smoothly discharged in the water in water storage device 4.
Those skilled in the art will readily recognize that above-mentioned each preferred embodiment can be free under the premise of not conflicting
Ground combination, superposition.
It should be appreciated that above-mentioned embodiment is merely exemplary, and not restrictive, without departing from of the invention basic
In the case where principle, those skilled in the art can be directed to the various apparent or equivalent modification or replace that above-mentioned details is made
It changes, is all included in scope of the presently claimed invention.
