The water purification control method of water purifying plant and control device and the water purifying plant proposed according to the embodiment of the present invention is just described with reference to accompanying drawing below.
Fig. 2 is the structural representation of the water purifying plant according to the embodiment of the present invention.As shown in Figure 2, this water purifying plant comprises: raw water box 1, clear water tanks 8, waste water tank 5, filtration unit 4 and control device 101.Wherein, be communicated with by the first pipeline 11 between filtration unit 4 with raw water box 1, be communicated with by the second pipeline 12 between filtration unit 4 with waste water tank 5, be communicated with by the 3rd pipeline 13 between filtration unit 4 with clear water tanks 8.
As shown in Figure 2, control device 101 comprises: topping-up pump 3, water level detecting module 102, controller 103.Wherein, topping-up pump 3 is arranged on the first pipeline 11; Water level detecting module 102 is for detecting the water level in clear water tanks 8; Controller 103 is connected with water level detecting module 102 respectively with topping-up pump 3, when clear water tanks 8 median water level is lower than the first preset water level and clear water tanks 8 lack of water, controller 103 controls topping-up pump 3 and starts working, and when clear water tanks 8 median water level is higher than the second preset water level and clear water tanks 8 full water, controller 103 controls topping-up pump 3 and quits work, wherein, the second preset water level is greater than the first preset water level.That is, controller 103 controls topping-up pump 3 according to the water position status of raw water box 1 and clear water tanks 8 and whether carries out work.
Particularly, as shown in Figure 2, water level detecting module 102 comprises the first detector switch 21 and the second detector switch 22.Wherein, whether the first detector switch 21 is for detecting clear water tanks 8 median water level lower than the first preset water level, and whether the second detector switch 22 is for detecting clear water tanks 8 median water level higher than the second preset water level.First detector switch 21 can be arranged on the bottom of clear water tanks 8, and the second detector switch 22 can be arranged on the top of clear water tanks 8.Namely say, the first detector switch 21 is for detecting clear water tanks 8 whether lack of water, and the second detector switch 22 is for detecting clear water tanks 8 whether full water.
Specifically, the state of clear water tanks 8 can be judged by the closed of the first detector switch 21 and the second detector switch 22 and off-state, such as, the first detector switch 21 is set and closes as clear water tanks exsiccosis; Arrange the second detector switch 22 to close as clear water tanks full water state.Like this, when powering on, if detect, the first detector switch 21 closes, then clear water tanks 8 lack of water, and controller 103 controls topping-up pump 3 and starts working to realize water purification filter; If detect, the second detector switch 22 closes, then clear water tanks 8 full water, controller 103 controls topping-up pump 3 and quits work.
In addition, as shown in Figure 2, water level detecting module 102 also comprises: the 3rd detector switch 23, i.e. raw water box lack of water detector switch.Whether 3rd detector switch 23 is for detecting raw water box 1 median water level lower than the 3rd preset water level, and the 3rd detector switch 23 can be arranged on the bottom of raw water box 1, wherein, when raw water box 1 median water level is lower than the 3rd preset water level and raw water box 1 lack of water, controller 103 controls topping-up pump 3 and quits work.That is, the 3rd detector switch 23 is for detecting raw water box 1 whether lack of water.
Similarly, the state of raw water box 1 can be judged by the closed of the 3rd detector switch 23 and off-state, such as, the 3rd detector switch 23 is set and closes as raw water box exsiccosis.Like this, when powering on, if detect, the 3rd detector switch 23 closes, then raw water box 1 lack of water, and controller 103 controls topping-up pump 3 and quits work, and user needs to add water to raw water box 1.
In an embodiment of the present invention, when the 3rd detector switch 23 closes, raw water box 1 lack of water, no matter clear water tanks 8 whether lack of water, controller 103 all controls topping-up pump 3 and quits work; Only have when raw water box 1 not lack of water time, if the first detector switch 21 closes, then clear water tanks 8 lack of water, controller 103 controls topping-up pump 3 and works, until clear water tanks 8 full water, the second detector switch 22 closes, and controller 103 controls topping-up pump 3 and quits work.
Particularly, in one embodiment of the invention, when controller 103 controls topping-up pump 3 according to the closed and disconnected state of detector switch, also need to preset stabilization time T1 according to actual needs, if in stabilization time T1, the state of detector switch remains unchanged, then judge the in stable condition of detector switch, exports the state of current detection switch; If the state of detector switch changes, then judge the state labile of detector switch, continue the state detecting detector switch.Such as, if detector switch is kept closed in T1, then judge that detector switch closes, the closure state of output detections switch; If the state of detector switch becomes disconnection from closed in T1, then judge the state labile of detector switch, continue the state detecting detector switch.For the 3rd detector switch 23 i.e. raw water box lack of water detector switch, when detecting that raw water box lack of water detector switch closes, and suppose that the time that raw water box lack of water detector switch closes continuously is T2, if T2 is more than or equal to T1, then raw water box lack of water detector switch closes in T1 always, and judging that raw water box lack of water detector switch is in stable condition, is closure state, the closure state zone bit K1_flag of raw water box lack of water detector switch is set to 1, and the state exporting former water lack of water detector switch is closed; When T2 is less than T1, then former water lack of water detector switch state changes, and judges raw water box lack of water detector switch state labile, continues the state detecting detector switch.
Further, after the state exporting current detection switch, also need to postpone certain T1 time of lag, T1 can design according to actual test result, such as, drain the time of water more than water tank, fill the time of water tank.If in time of lag T1, the state of detector switch remains unchanged, then judge that the state of water tank is lack of water or full water state always.Such as, if the 3rd detector switch 23 i.e. raw water box lack of water detector switch closes, then raw water box 1 lack of water is judged; If the first detector switch 21 i.e. clear water tanks lack of water detector switch closes, then judge clear water tanks 8 lack of water; If the second detector switch 22 i.e. clear water tanks full water detector switch closes, then judge clear water tanks 8 full water.For raw water box 1 lack of water, suppose that the closure state zone bit K1_flag of raw water box lack of water detector switch is 1, then, after T1 time of lag, K1_flag is 1 always, then raw water box lack of water zone bit gbSCRwaterFlag is set to 1.
In one particular embodiment of the present invention, the first detector switch 21, second detector switch 22 and the 3rd detector switch 23 can be dry-reed tube proximity switch, one of capacitive approach switch or vernier switch.Which reduces the water level detecting failure phenomenon caused because water tank uses breed bacteria to produce ball float adhesion for a long time, improve the reliability of water level detecting.

Particularly, as shown in Figure 3 B, the 3rd detector switch 23 can be capacitive approach switch, when raw water box 1 lack of water, capacitive approach switch closes, by the signal feedback of raw water box 1 lack of water to controller 103, controller 103 controls water purification topping-up pump 3 and works, and enters exsiccosis.
Particularly, as shown in Figure 3 C, 3rd detector switch 23 can be vernier switch, when user puts into raw water box 1, touches vernier switch, vernier switch closure signal is fed back to controller 103, controller 103 controls topping-up pump 3 and works, and starts water purification, if clear water tanks 8 full water detected, then controller 103 controls topping-up pump 3 and quits work, and enters exsiccosis; If after the maximum water purification time, still can't detect clear water tanks 8 full water, then controller 103 controls topping-up pump 3 and quits work, and enters exsiccosis.
In one embodiment of the invention, as shown in Figure 2, control device 101 also comprises: wastewater valve 7, wastewater valve 7 is arranged on the second pipeline 12, and wastewater valve 7 is connected with controller 103, wherein, controller 103 according to the capacity of raw water box 1 and the calculation of capacity topping-up pump 3 of waste water tank 7 and the working hour ratio of wastewater valve 7, and controls topping-up pump 3 and wastewater valve 7 respectively according to working hour ratio.Thus can realize having filtered one case former water, be just booked one case waste water.
That is, according to the capacity of raw water box 1 and the capacity of waste water tank 7, flush time T can be calculated, namely after topping-up pump 3 working hour T, controller 103 controls wastewater valve 7 and works, and rinses filtration unit 4, and the waste water after rinsing is entered waste water tank 5 by the second pipeline connection 12.
Thus, the water purifying plant of the embodiment of the present invention, according to the best effort time scale of topping-up pump and wastewater valve, can realize having filtered one case former water, just be booked one case waste water, decrease the quantity discharged of waste water and user and fall the number of times of waste water, convenient for users to use.In another embodiment of the present invention, as shown in Figure 2, raw water box 1 and waste water tank 7 become one.Such user can complete raw water box simultaneously and add water and the operation of waste water tank pouring, decreases the operation steps of user, convenient for users to use.
In an embodiment of the present invention, when the 3rd detector switch 23 detects raw water box 1 lack of water, controller 103 controls topping-up pump 3 and quits work, and enters exsiccosis, needs user to add water to raw water box 1; When raw water box 1 not lack of water time, if the first detector switch 21 detects clear water tanks 8 lack of water, then controller 103 controls topping-up pump 3 and works, water purifying plant starts water purification, until the second detector switch 22 detects clear water tanks 8 full water, then controller 103 controls topping-up pump 3 and quits work, and water purifying plant stops water purification.Further, when topping-up pump 3 works, need after regular hour such as flush time T, controller 103 controls wastewater valve 7 and works, washing and filtering device 4, simultaneously by discharge of wastewater in waste water tank 5.
