The water purifier comprises a water purifier body; a water inlet of the purifier body is communicated with a water outlet through filter devices which are connected in series; the water outlet is connected with a water taking end through a water outlet pipeline; the water outlet pipeline is connected in parallel with a water discharging pipeline which is controlled by a washing solenoid valve; a flow sensor device is arranged in the water outlet pipeline; a signal output end of the flow sensor device is connected with a signal input end of a timing control circuit; and a control output end of the timing control circuit is connected with a controlled end of the washing solenoid valve. Time when water does not flow in the water purifier does not exceed the time threshold value by timed washing control, so that stagnant water can be avoided, and bacteria can be prevented from breeding by washing the surface of a filter element at fixed time; and the quality of outlet water can always meet the purification requirement.

Description

A kind of timing flushing water-purifying machine

Technical field

The utility model relates to a kind of water-purifying machine, and especially a kind of timing flushing water-purifying machine belongs to the water treatment technology field.

Background technology

Micro-filtration/ultrafiltration water-purifying machine for a long time need not after, inner water can not become " stagnant water " because do not flow for a long time.Simultaneously, the impurity that dams in each filter core surface of water-purifying machine, organism are easy to breed bacteria when water does not flow, influence effluent quality.Understand according to the applicant, some micro-filtration ultrafiltration water-purifying machines have manual washing function on the market at present, and the flush valve that is arranged on the filtration unit (filter flask) through artificial unlatching comes the washing and filtering cartridge surface.But this mode can not solve in the human consumer family long-time nobody the time water-purifying machine inner " stagnant water " problem with water when mobile bacterium more be prone to the problem of growing.

The utility model content

The purpose of the utility model is: to the problem that above-mentioned prior art exists, propose a kind of water-purifying machine with timing washing function, thereby guarantee that effluent quality satisfies the purification requirement.

In order to reach above purpose; The timing flushing water-purifying machine basic technical scheme of the utility model is: comprise the water-purifying machine body; The water-in of said body leads to water outlet through series filtration unit; Said water outlet accesses water end (W.E.) through outlet pipeline, and its improvements are: said outlet pipeline is parallelly connected with the discharge pipe line of scouring electromagnetic valve control, and said water-purifying machine also comprises the flow sensing device; The signal output part of said flow sensing device connects the signal input part of time control circuit, and the control output end of said time control circuit connects the controlled end of said scouring electromagnetic valve.

When water-purifying machine does not use; When the flow sensing device detected less than flow signal, timing register picked up counting in the time control circuit, when the timing register cumulative time reaches the setting-up time threshold value; The controlled opening scouring electromagnetic valve makes water-purifying machine regularly obtain flushing through discharge pipe line.Do not reach scheduled time threshold value flow sensing device like the timing register cumulative time and promptly detect water-flow signal, explain that water-purifying machine is used, be about to the timing register zero clearing.

Like this; Can guarantee that the time of the obstructed current of water-purifying machine is no more than time threshold by flushing control regularly, both avoid generation " stagnant water ", again because regularly the filter core surface is washed; Avoided breed bacteria, thereby guaranteed that all the time effluent quality satisfies the purification requirement.

Embodiment

Embodiment one

The timing flushing water-purifying machine substruction of present embodiment is as shown in Figure 1; The water-in IN of water-purifying machine body 1 leads to water outlet OUT through placed in-line two-stage (also can be single-stage or multistage) filtration unit 2; Water outlet accesses water end (W.E.) 3 through outlet pipeline 4; Wherein outlet pipeline 4 is parallelly connected with the discharge pipe line 5 of scouring electromagnetic valve 6 controls, and the terminal of discharge pipe line 5 is water port P.Flow sensing device 7 is housed in the outlet pipeline 4, and the signal output part of this flow sensing device connects the signal input part of time control circuit 8, and the control output end of time control circuit 8 connects the controlled end of scouring electromagnetic valve 6.

The physical circuit of time control circuit is as shown in Figure 2; Wherein S1 is flow sensing device (being 7 among Fig. 1); Its signal output part connects the MCU chip input terminus as time control circuit, and the control output end of this MCU chip is through driving the controlled end that triode Q2 connects scouring electromagnetic valve VA1 (being 6 among Fig. 1).

Increased the flow sensing device between the water outlet of present embodiment and the water intaking end, the flow sensing device provides flow signal to pilot circuit; And the feed-water end of scouring electromagnetic valve is parallelly connected with the water intaking end, and the water intaking end is connected to water port, is in normally off; When the flow sensing device detected less than flow signal, timing register picked up counting:

1) when the flow sensing device detects flow signal once more, the timing register cumulative time is less than setting-up time T1, the timing register zero clearing;

2) before the flow sensing device detects flow signal once more, the timing of timing register accumulative total has reached setting-up time T1, and scouring electromagnetic valve is opened, and system is washed, and closes after the flushing certain time interval T 2; The timing register zero clearing.

Like this, can guarantee that the time of the obstructed current of water-purifying machine is no more than time threshold T1 by regularly flushing control; Thereby both avoided generation " stagnant water "; Because regularly the filter core surface is washed, also avoided breed bacteria again, can guarantee all the time that effluent quality satisfies the purification requirement.

In addition, the flow sensing device also can be arranged on the body or inlet tube and outlet tube etc. can detect normal position with discharge.

Embodiment two

The timing flushing water-purifying machine substruction of present embodiment is as shown in Figure 3; Be with embodiment one difference; Last step one of (also can be at different levels) filtration unit has sewage draining exit 9; This sewage draining exit is through the run in water port of water lines 5 of the blow-off line 11 that washing SV 10 is housed, and another control output end of time control circuit 8 connects the controlled end of washing SV 10.The physical circuit schematic diagram of time control circuit is seen Fig. 4, and referring to the explanation of Fig. 2.

During work, the opened/closed state of washing SV is controlled by pilot circuit.When the flow sensing device detected less than flow signal, timing register picked up counting.

1) when the flow sensing device detects flow signal once more, the timing register cumulative time is less than setting-up time T3, the timing register zero clearing;

2) before the flow sensing device detects flow signal next time, the timing of timing register accumulative total has reached setting-up time T3, and the washing SV is opened, and water-purifying machine last step filter core (or the important filter core in certain road) is washed, and closes after the flushing certain time interval T 4; Scouring electromagnetic valve is opened in the time of the washing closed electromagnetic valve, and system is washed, and closes the timing register zero clearing after the flushing certain time interval T 5.

Said flow sensing device is the device that flow sensor or flow valve etc. can inductive flows; At said water intaking end water intaking tap or intake can be set directly, containers such as cold jar, heating kettle or water tank also can be set in addition.

Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme that replacement forms, and all drop on the protection domain of the utility model requirement.
