Below, the action and the effect of the device for informing changing period of filter of the water purifier of the present invention with above-mentioned structure are described.
Fig. 7 A-Fig. 7 D represents the flow process of the informing changing period of filter control action order of water purifier of the present invention, and S represents step among the figure.
First trip, the water purifier energized is transformed to the supply voltage of the commercial ac power source of the ac power input end supply of scheming not show the required predetermined value DC voltage of driving water purifier and exports to each driving circuit and control device 108 at continuous-current plant 102.
Therefore, at step S1, the DC voltage of continuous-current plant 102 outputs makes the water purifier initialization by control device 108 inputs.At step S2, control device 108 judges whether the DC voltage that continuous-current plant 102 applies is that primary power is whether power supply is connected.
If the judged result power supply access failure of step S2 enters step S3, primary power is connected water purifier and is counted the elapsed time by the timer that is contained in the control device 108.At step S4, the water purification amount that detects the reserve tank 35 that stores water purification by condensate tank of dehumidifier 104 is the water level of reserve tank 35, and detected waterlevel data is exported to control device 108.
Therefore, control device 108 judge the water level of the reserve tank 35 that detects by condensate tank of dehumidifier 104 whether be " in " more than, this be by the poor-water position detecting sensor 39 detected resistance values that are contained in reserve tank 35 inside rear by control device 108 inputs judge the water level of reserve tank 35 whether be " in " above.
The judged result of step S4 be the water level of reserve tank 35 be " in " when above, can not supply with water purification to reserve tank 35, so enter step S41, control device 108 outputs to water-supply valve drive unit 112 to the control signal of inaccessible water-supply valve 57.
Therefore, water-supply valve drive unit 112 cuts off the supply voltage of water-supply valve 57 according to the control of control device 108, makes water-supply valve 57 obturations.
After water-supply valve 57 obturations, return step S4 the decline of water table of reserve tank 35 to " in " following before, control device 108 is waited on one side and is done the water purification action, Yi Bian carry out the action below the step S4 repeatedly.
The judged result of step S4 be the water level of reserve tank 35 be not " in " when above, carry out supplying with the action of water purification to reserve tank 35, at step S5, control device 108 outputs to water-supply valve drive unit 112 to the control signals of open water-supply valves 57.
Therefore, water-supply valve drive unit 112 to water-supply valve 57 supply line voltages, makes water-supply valve 57 open according to the control of control device 108.
At this moment, at step S6,, begin to count present filtrator service time by the timers that are contained in the control device 108 because of after the opening of water-supply valve 57 makes reset service time of filtrator.
Water-supply valve 57 is in case open, begin in feed pipe 25, to supply with water such as tap water by pipe adapter 23 from water halter 22, at step S7, in order to make the water of supplying with in the feed pipe 25 that also flows into infiltration diaphragm device 29 rise to predetermined pressure, control device 108 outputs to pump drive 110 to the control signal that drives force (forcing) pump 59.
Like this, pump drive 110 is accepted the control signal of control device 108 outputs, to force (forcing) pump 59 supply line voltages, force (forcing) pump 59 is driven.
Force (forcing) pump 59 is in case drive, at step S8, along with the opening of water-supply valve 57 is removed various harmful organic compound materials such as chlorine on one side on one side from the water that water halter 22 supplies in the feed pipe 25 by pre-treatment filtrator 27, the water that has passed through pre-treatment filtrator 27 flows into infiltration diaphragm devices 29 by water-supply valve 57.
At this moment, the water of inflow infiltration diaphragm device 29 is along with the driving of force (forcing) pump 59 is risen to predetermined pressure, by infiltration diaphragm device 29, flow into several permeable membranes in the water infiltrate infiltration on one side diaphragm device 29 that permeates diaphragm device 29, Yi Bian be removed each heavy metal species, carcinogen, bacterium etc.
The water that has passed through infiltration diaphragm device 29 is supplied with reserve tanks 35 by giving water hole 33 after being removed the smell component of toxic gas etc. by posttreatment filter 31 once more.
Having passed through pre-treatment filtrator 27 flows in the water of infiltration diaphragm device 29, after condensed water that can not the infiltrate permeable membrane flows into box part from infiltration diaphragm device 29 by the 1st inflow entrance 67a, along with the action of the obturation of solenoid valve 65 can not flow in the connecting pipe 73, shown in the arrow among Fig. 4, and, discharge outside by drainpipe 63 by the drainage channel 71 in the through hole 69a inflow water drainage part 69.
At this moment, flow into the water purification of preprocessor 31 and be not about 1: 2 through the ratio of the condensed water of drainpipe 63 discharges by infiltration diaphragm device 29 backs by infiltration diaphragm device 29.
Then, the water purification amount that is detected by condensate tank of dehumidifier 104 in the water purification action at step S8 by supplying with in the reserve tanks 35 for water hole 33 at step S9 is the water level of reserve tank 35, should export to control device 108 by detected waterlevel data.
Therefore, control device 108 judge reserve tank 35 water levels that detect by condensate tank of dehumidifier 104 whether be " on " more than, this be by the full-water level detecting sensor 37 detected resistance values that are contained in reserve tank 35 inside rear by control device 108 inputs judge the water level of reserve tank 35 whether be " on " above.
The judged result of step S9 be the water level of reserve tank 35 be not " on " when above, should continue to supply with water purification to reserve tank 35, return step 8 on one side and carry out water purification and move and carry out action below the step S8 repeatedly.
The judged result of step S9 be the water level of reserve tank 35 be " on " when above, should end to supply with water purification to reserve tank 35, enter step S10, control device 108 outputs to water-supply valve drive unit 112 to the control signal of inaccessible water-supply valve 57.
Therefore, water-supply valve drive unit 112 cuts off the supply voltage of water-supply valve 57 according to the control of control device 108, makes water-supply valve 57 obturations.
At this moment, at step S11, be contained in timer in the control device 108 along with the obturation of water-supply valve 57 ends the timing action of service time of present filtrator is entered step S12, control device 108 is exported to pump activation point 110 to the control signals that stop force (forcing) pump 59.
Like this, pump drive 110 cuts off the supply voltage of force (forcing) pump 59 according to the control of control device 108, and force (forcing) pump 59 is stopped.
In case water-supply valve 57 obturations, force (forcing) pump 59 stops, and stops water halter 22 to supply water in feed pipe 25 and no longer supply with water purification in reserve tank 35, and the water purification action is stopped.
Then, whether the power connection time that the timer in step S13 judges control device 108 is counted in step S3 has passed through the schedule time (about 12 hours), if do not pass through, then enter step S14, control device 1 08 judges whether the reset switch 51,53,55 of the key input apparatus 106 of reset service time that is used to make pre-treatment filtrator 27, infiltration diaphragm device 29 and posttreatment filter 31 is connected.
This judgement is by judging that the user makes when the replacing of pre-treatment filtrator 27, infiltration diaphragm device 29 and posttreatment filter 31 in the reset switch 51,53,55 that is installed on each filtrator any be on-state.
When the judged result of step S14 is reset switch 51,53,55 access failures, return step S4, carry out action below the step S4 repeatedly while continue to detect water levels in the reserve tank 35; When the judged result of step S14 is reset switch 51,53,55 ons, enter step S15, control device 108 is exported to electromagnetic valve actuator 114 cleaning the control signal of discharging automatically attached to the rinse water of foreign matter on the infiltration diaphragm device 29.
Therefore electromagnetic valve actuator 114 to solenoid valve 65 supply line voltages, makes solenoid valve 65 open according to the control of control device 108.
Rinse water in the inflow box part 67 is along with the opening operation of solenoid valve 65, shown in the arrow among Fig. 5,73 flow in the box part 67 by the 2nd inflow entrance 67b again from solenoid valve 65 to connecting pipe, after flowing in the drainage channel 71 that is formed on water drainage part 69 inboards by several through holes 69a, discharge the outside by drainpipe 63, carry out the automatic discharging operation of rinse water.
At this moment, the water that flows into infiltration diaphragm devices 29 through pre-treatment filtrator 27 pass through permeable membrane on one side and passes through drainpipe 63 discharge outsides, so do not carry out water purification by permeable membrane sheet device 29.
Then, at the opening operation of step S17 judgement along with solenoid valve 65, rinse water begins to discharge whether passed through the schedule time (about 3 minutes), if do not pass through the schedule time, then returns step S15, carries out the following action of step S15 repeatedly.
The judged result of step S17 is if pass through the schedule time, then think and be removed attached to foreign matters such as each heavy metal species on the infiltration diaphragm device 29, carcinogen, bacteriums, at step S18, control device 108 is exported to electromagnetic valve actuator 114 to the control signal of inaccessible solenoid valve 65.
Therefore, electromagnetic valve actuator 114 cuts off the supply voltage of solenoid valve 65 according to the control of control device 108, makes solenoid valve 65 obturations.
Certainly, water purification at this moment also keeps being about 1: 2 with the ratio of condensed water.
Then, at step S19, control device 108 is read previous filtrator service time of being stored in the memory storage 116 (from the replacing of filtrator already used filtrator service time till now constantly), at step S20, the present filtrator of control device 108 counting is added the previous filtrator service time that is stored in the memory storage 116 service time, after calculating the full service time of filtrator, this filtrator of calculating is stored in the memory storage 116 full service time.
Therefore, at step S21, judge whether is the changing period of filter (life-span of filtrator ends period) that is set in advance in the control device 108 the filtrator full service time be stored in the memory storage 116, if not, then enter step S22, whether judge that whether the filtrator full service time be stored in the memory storage 116 be to be set in advance in preceding 10 days of changing period of filter in the control device 108, that is, be preparation replacing period.
The judged result of step S22 if be not preparation replacing period (changing period of filter preceding 10 days) the full service time of filtrator, then enters step S23, and control device 108 judges whether it is the period of replacing by force of filtrator.
Be meant the so-called period of changing filtrator forcibly produce peculiar smell in the reserve tank or foreign matter is arranged or situation that the water purification water yield is few under, even not to the period that should change filtrator, according to user's judgement, think that filtrator has damaged or the life-span has ended and should change the state of filtrator.
The judged result of step S23, if should change the period of filtrator by force, then enter step S24, whether any connects at least in the reset switch 51,53,55 of the filtrator that the judgement preparation is changed, and the on-state of reset switch is meant that the user pushes the situation of reset switch 51,53,55 five seconds of corresponding each filtrator.
The judged result of step S24 if reset switch the 51,53, the 55th is connected, then enters step S5, and control device 108 is exported to display device 118 to the control signal that the expression users wish to change by force the state of filtrator.
Therefore, display device 118 makes the bright lamp of red LED of the filtrator that need change by force according to the control of control device 108.
Then, at step S26, judge that reset switch 51,53,55 is after step S24 connects, whether (1 minute) is connected once more with interior reset switch 51,53,55 at the fixed time, if connect once more, then be judged as filtrator and changed by force by the user, enter step S27, the control signal that control device 108 is changed filter state by force to expression is exported to display device 118.
Like this, display device 118 makes the bright lamp of blue look LED of the filtrator that need change by force according to the control of control device 108.
As mentioned above, in case filtrator is changed by force by the user, at step S28, in order to restart to count the life-span of the filtrator of being changed by force, control device 108 makes present filtrator service time and is stored in full reset service time of filtrator in the memory storage 116.At step S29, the water purification amount that condensate tank of dehumidifier 104 detects reserve tank 35 is the water level of reserve tank 35, and the waterlevel data that detects is exported to control device 108.
Therefore, control device 108 judge reserve tank 35 water levels that condensate tank of dehumidifier 104 detected whether be " in " more than, this be by the poor-water position detecting sensor 39 detected resistance values that are contained in reserve tank 35 inside rear by control device 108 inputs judge the water level of reserve tank 35 whether be " in " above.
The judged result of step S29, if the water level of reserve tank 35 be not " in " when above,, return step S5 in order to carry out supplying with the water purification action of water purification to reserve tank 35, carry out the following action of step S5 repeatedly.
The judged result of step S29, if the water level of reserve tank 35 be " in " when above, can not supply with water purification to reserve tank 35, so enter step S30, control device 108 stops the water purification action, finishes whole action.
In addition, the judged result of step S21 if filtrator full service time be changing period of filter, then enters step S40, and control device 108 is exported to display device 118 to the control signal of expression " be should change filtrator period ".
Therefore, display device 118 makes the LED of the filtrator that should change glittering according to the control of control device 108.
Then, at step S41, control device 108 is exported to alarm tone generating means 120 to the control signal of reporting " being to change period ".
Like this, alarm tone generating means 120 is according to the control of control device 108, and the sound that gives the alarm enters step S42, and control device 108 judges whether this filtrator is replaced.
Judge whether that the method that should change this filtrator is: after judging that the user has changed this filtrator, whether make corresponding to the reset switch 51,53,55 of this filtrator and connect (having pushed the five seconds state).
The judged result of step S42, if changed this filtrator, then enter step S28, in order to restart to count the filter life of having changed, control device 108 makes present filtrator service time and is stored in full reset service time of filtrator in the memory storage 116, and carries out the following action of step S28 repeatedly.
The judged result of step S42 if do not change this filtrator, then enters step S30, and control device 108 stops the water purification action, finishes whole action.
The judged result of step S22, if be preparation replacing period (changing period of filter preceding 10 days) the full service time of filtrator, then enter step S50, control device 108 is exported to display device 118 to this control signal of expression " surplus have should change filtrator period ".
Therefore, display device 118 makes the bright lamp of LED of the filtrator that should change according to the control of control device 108.
Then, at step S51, control device 108 is exported to alarm tone generating means 120 to the control signal of reporting " surplus have should change filtrator period ".
Like this, alarm tone generating means 120 is according to the control of control device 108, and the sound that gives the alarm enters step S52, and control device 108 judges whether this filtrator is replaced.
