Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, a method for detecting water leakage from a water purifier system is provided, as shown in fig. 1, including:
step S110: and acquiring detection data sent by a water flow detector of the water purifier system.
The detection data is obtained by detecting the water flow state in the pipeline where the water flow detector is located. Specifically, the detection data transmitted from the water flow detector of the water purifier system may be received by the controller. The controller can adopt a single control chip or utilize the existing main control board of the water purifier system. In the embodiment, the controller adopts the existing main control board of the water purifier system, and the existing main control board of the water purifier system is used for data collection and analysis, so that a new processing chip is not needed, and the water leakage detection cost is also reduced.
The water purifier system specifically comprises a preposed filter element, a water inlet valve, a filter element, a check valve and other devices which are sequentially connected through a pipeline, and a water flow detector of the water purifier system is arranged in the pipeline and used for detecting the water flow state in the pipeline, obtaining detection data and sending the detection data to the controller. The position and type of the water flow detector are not exclusive, and the position of the water flow detector can be arranged at the front section and/or the rear section of the check valve, and in addition, the water flow detector can adopt TDS probes, pressure switches, flow meters and other devices.
Step S120: and performing water leakage detection analysis on the water purifier system according to the detection data to obtain a water leakage detection result.
After receiving the detection data sent by the water flow detector, the controller can carry out water leakage detection and analysis on the water purifier system by combining the detection data and the pre-stored detection standard, judge whether the water purifier system has water leakage phenomenon or not and obtain a water leakage detection result. For example, if the detection data meets the detection standard, it is determined that a water leakage phenomenon occurs, and the water leakage detection result is that water leakage is detected. If the detection data does not meet the detection standard, the water leakage phenomenon is not detected, and the water leakage detection result is that water leakage is not detected. When the detection data meets the detection standard, the detection can be subdivided into the detection of obvious water leakage or water leakage, and the water leakage can be considered to be detected as long as one of the two conditions is met.
Step S130: and when the water leakage detection result is that water leakage is detected, outputting a valve closing instruction to a water inlet valve of the water purifier system.
The close valve command is used to control the inlet valve to close. When the controller detects that the water purifier system leaks, the controller sends a valve closing instruction to control the water inlet valve of the water purifier system to be closed, so that continuous water leakage is avoided, and a protection effect is achieved.
In addition, when the water leakage detection result is that water leakage is detected, the method may further include the step of outputting a water leakage prompt message. For example, the controller can remind the user that water leakage occurs in the water purifier system by controlling the display to display preset information and controlling the prompt lamp to flicker or the loudspeaker to sound, so that the user can conveniently and timely overhaul the water purifier system. Further, after the water leakage detection result is obtained, the method may further include the step of displaying the water leakage detection result. The controller sends the detection result that leaks to the display and shows, and the convenience of customers looks over.
According to the water leakage detection method of the water purifier system, water leakage detection is performed by combining the data detected by the original water flow detector of the water purifier system, a separate water leakage detection module is not required to be additionally arranged, and the detection cost is reduced by the water leakage detection method of the traditional water purifier.
In one embodiment, the water flow detector includes a front water flow detector disposed at a front stage of the check valve of the water purifier system, as shown in fig. 2, and the step S110 includes a step S112.
Step S112: when the water purifier system is not in a water making state, the detection data detected by the front-section water flow detector is received.
Wherein, the water making state means that the water purifier system is in a water purifying mode. Specifically, a check valve of the water purifier system is connected with a faucet through a pipeline. The water tap is a double-outlet water tap and is provided with two inlets and one outlet. The water path behind the front-section water flow detector is divided into two branches, and one branch is connected with a water tap through a filter element, a check valve and the like; the other branch is directly connected with a water tap. When a water tap is turned on and a water purification end is started, the water purifier system enters a water production mode, and purified water is prepared by pressurizing through a water pump; when the domestic water end of the water faucet is opened, domestic water is pressed out through the water of tap water, and the domestic water only passes through the preposed filter element without pressurization.
When the water purifier system is not in the water making state, the water inlet valve is closed, and no water flows under the condition that the water faucet is closed. At this moment, the water flow state of the front section of the check valve is collected through the front section water flow detector arranged on the front section of the check valve, so that whether water leakage occurs to the front section of the check valve or not is detected by the controller.
Correspondingly, in one embodiment, the fore stream water flow detector comprises a TDS probe, and with continued reference to fig. 2, step S120 comprises step S122.
Step S122: if the TDS value that the TDS probe detected is less than preset TDS threshold value, then the detection result that leaks appears leaking for the check valve anterior segment of water purifier system.
The specific value of the TDS threshold is not unique, and can be adjusted according to the detection precision of actual needs. If the check valve anterior segment appears leaking, the water between water intaking valve and the check valve can the light leak after a period of time, TDS probe can expose in the air this moment, and the TDS detected value can be close 0, and the TDS value of most running water all is greater than 100, so when TDS value < TDS threshold value, can judge that the check valve anterior segment appears obviously leaking.
In this embodiment, carry out the TDS value of rivers in the pipeline through the TDS probe that sets up at the check valve anterior segment and detect to send and carry out the analysis to the controller, realize detecting whether obvious leaking appears the check valve anterior segment.
Further, in one embodiment, as shown in FIG. 2, the front-end flow detector comprises a back-up valve front-end flow meter; step S120 includes step S124.
Step S124: if the flowmeter at the front section of the check valve detects water flow, the water leakage detection result indicates that water leakage occurs at the front section of the check valve of the water purifier system.
Likewise, when the water purifier system is not in the water producing state, the water inlet valve is closed. If the front section of the check valve has water leakage, the flowmeter at the front section of the check valve can detect water flow, and the controller can judge that the front section of the check valve has water leakage. The water flow detection is carried out through the flowmeter at the front section of the check valve, and the obvious water leakage detection on the front section of the check valve can be realized.
In addition, the front-stage water flow detector may also include a TDS probe and a check valve front-stage flow meter, and correspondingly, step S120 includes step S122 and step S124. Meanwhile, the water leakage detection of the front section of the check valve is carried out by combining a TDS probe and a flowmeter, and the detection is more accurate.
In one embodiment, the water flow detector includes a rear water flow detector disposed at a rear portion of a check valve of the water purifier system, as shown in fig. 3, and the step S110 includes a step S114.
Step S114: and when the water purifier system is in a water making state, receiving detection data detected by the rear-section water flow detector.
When the water purifier system is in a water making state, the water inlet valve is opened, and the water flow state of the rear section of the check valve is detected by the rear-section water flow detector, so that when the water purifier system is in the water making state, the controller detects whether water leakage occurs in the rear section of the check valve.
Correspondingly, in one embodiment, with continued reference to fig. 3, step S120 includes step S126.
Step S126: and if the single water production amount is judged to be larger than the preset water production amount threshold value according to the detection data of the rear-section water flow detector, the water leakage detection result is that water leakage occurs at the rear section of the check valve of the water purifier system.
Specifically, the back-end water flow detector may be a pressure switch or a back-end flow meter of a check valve. The water purifier system detects whether the water tap is closed or not through a pressure switch or a rear-section flowmeter of the check valve, so that whether water production is needed or not is determined. The specific value of the water production threshold is not unique, and in this embodiment, the water production threshold is far higher than the threshold of a single water intake used by a user normally. After the system determines that water is needed to be made, the water making speed can be determined according to set parameters, the water making time determined according to the conduction duration of the pressure switch is combined with the water making speed to count the single water making quantity, or the single water making quantity can be counted according to the counting of the flow meter at the rear section of the check valve, so that whether the water making quantity is far higher than the single water taking quantity normally used by a user or not is judged, and further whether obvious water leakage occurs at the rear section of the check valve or not is judged.
In this embodiment, when the water purifier system is in system water state, adopt back end rivers detector to carry out water flow statistics to the check valve back end to whether the realization appears obviously leaking to the check valve back end and detects.
In one embodiment, the water flow detector comprises a check valve rear section water flow detector, as shown in fig. 4, and step S110 comprises step S116.
Step S116: and when the water purifier system is not in a water production state, receiving detection data detected by the rear-section water flow detector.
When the water purifier system is not in the water making state, the water inlet valve is closed. The water flow state of the back section of the check valve is detected by the back section water flow detector, so that when the water purifier system is not in a water making state, the controller detects whether water leakage occurs in the back section of the check valve.
Correspondingly, in one embodiment, with continued reference to fig. 4, step S120 includes step S128.
Step S128: and if the frequency of abnormal water production is judged to be larger than the set frequency threshold according to the detection data of the rear-section water flow detector, the water leakage detection result is that water leakage occurs at the rear section of the check valve of the water purifier system.
Adopt pressure switch as an example in the later stage rivers detector, when the dribbling appears in the check valve back end, need the pressure of a period of back check valve back end just can reduce a definite value to make pressure switch detect the low pressure, the system begins system water this moment, because system water speed is far greater than the speed of dribbling, will stop system water in a plurality of seconds, if the condition of the short period of system water appears frequently in a period can judge that the dribbling appears in the check valve back end.
Specifically, the water making time is determined according to the conduction duration of the pressure switch, the single water making quantity can be counted by combining the water making speed, if the single water making quantity is smaller than a set abnormal water making threshold value, abnormal water making can be considered to occur once, and when the accumulated abnormal water making times reach a preset time threshold value, the rear section of the check valve can be judged to have water leakage. The specific values of the abnormal water production threshold and the time threshold are not unique, and can be adjusted according to actual requirements.
Wherein, the abnormal water making threshold is far smaller than the water making threshold, namely when the water purifier system is not in the water making state, the controller detects that the water making amount is smaller than the abnormal water making threshold, and records one time of abnormal water making; when the water purifier system is in a water production state, if the controller detects that the water production amount is greater than the water production amount threshold value, the water purifier system judges that obvious water leakage occurs.
It can be understood that the single water production amount can be calculated by the water production time and the water production speed. In other embodiments, when the water leakage detection and analysis is performed according to the detection data detected by the rear-stage water flow detector, it may also be directly analyzed whether obvious water leakage or water leakage occurs according to the length of the water production time. Similarly, the rear-section water flow detector adopts a pressure switch as an example, when the water purifier system is in a water making state, if the single water making time detected by the pressure switch is greater than a set value 1, the single water making quantity can be considered to be far higher than the single water taking quantity normally used by a user, and obvious water leakage occurs at the rear section of the check valve. When the water purifier system is not in a water making state, if the single water making time is detected to be less than the set value 2 through the pressure switch, one abnormal water making can be considered to occur. Wherein the set value 2 is much smaller than the set value 1.
In addition, the rivers detector still can include anterior segment rivers detector and back end rivers detector simultaneously, and the controller detects check valve anterior segment and check valve back end according to the state of water purifier system, combines the data that anterior segment rivers detector and back end rivers detector gathered, can detect the part that specifically leaks before the check valve or behind the check valve on the basis that need not to increase hardware cost to and detect out whether obviously leak or the water clock. When obvious water leakage or water dripping occurs, the water leakage detection result is that water leakage is detected, the controller controls the water inlet valve to be closed, and water leakage prompt information is sent out; if no obvious water leakage or water dripping occurs, the water leakage detection result indicates that no water leakage is detected, and the water purifier system continues to normally operate.
In one embodiment, as shown in fig. 5, the method further includes step S140.
Step S140: and recording the whole machine running time of the water purifier system, and resetting the abnormal water making times and the whole machine running time when the whole machine running time reaches a preset running time threshold value.
The value of the running time threshold is not unique, specifically, the controller records the running time of the whole water purifier system in real time, and accumulates the times of abnormal water production to analyze whether the back section of the check valve has water leakage or not. When the running time of the whole water purifier system reaches the running time threshold, the abnormal water making times and the running time of the whole water purifier system are reset, the interference of the abnormal water making times accumulated by the long-time running of the water purifier system on the rear-section water leakage detection of the check valve is avoided, and the accuracy of the water leakage detection is improved.
In one embodiment, a water leakage detection device for a water purifier system is further provided, as shown in fig. 6, including a data acquisition module 110, a data analysis module 120, and a water valve control module 130.
The data acquisition module 110 is used for acquiring the detection data sent by the water flow detector of the water purifier system. And the detection data is obtained by detecting the water flow state in the pipeline where the water flow detector is located.
The data analysis module 120 is configured to perform water leakage detection and analysis on the water purifier system according to the detection data to obtain a water leakage detection result.
The water valve control module 130 is configured to output a valve closing instruction to a water inlet valve of the water purifier system when the water leakage detection result indicates that water leakage is detected; the close valve command is used to control the inlet valve to close.
In addition, the device still can include information output module, and when the detection result that leaks was for detecting the leak, information output module output leaks prompt message and reminds user's water purifier system to leak, and convenience of customers overhauls in time. Furthermore, after the water leakage detection result is obtained, the information output module can also display the water leakage detection result, so that the user can conveniently check the water leakage detection result.
In one embodiment, the water flow detector includes a front-stage water flow detector disposed in a front stage of the check valve of the water purifier system, and the data acquisition module 110 receives detection data detected by the front-stage water flow detector when the water purifier system is not in a water production state.
Correspondingly, in one embodiment, the fore-stream water flow detector comprises a TDS probe. When the TDS value detected by the TDS probe is less than the preset TDS threshold, the data analysis module 120 detects that water leaks for the check valve front section of the water purifier system.
Further, in one embodiment, the front end flow detector comprises a back end flow meter. When the flow meter at the front section of the check valve detects water flow, the data analysis module 120 determines that water leakage occurs at the front section of the check valve of the water purifier system.
In one embodiment, the water flow detector includes a back-end water flow detector disposed at a back end of the check valve of the water purifier system, and the data acquisition module 110 receives detection data detected by the back-end water flow detector when the water purifier system is in a water producing state.
Correspondingly, in an embodiment, the data analysis module 120 determines that the water production amount per time is greater than the preset water production threshold according to the detection data of the back-stage water flow detector, and the water leakage detection result is that water leakage occurs at the back stage of the check valve of the water purifier system.
In one embodiment, the water flow detector comprises a check valve back-end water flow detector, and the data acquisition module 110 receives detection data detected by the back-end water flow detector when the water purifier system is not in the water producing state.

The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.
The water leakage detection device of the water purifier system is used for detecting water leakage by combining the data detected by the original water flow detector of the water purifier system, and a separate water leakage detection module is not required to be additionally arranged, so that the detection cost is reduced by using the water leakage detection device of the traditional water purifier.
In an embodiment, a water purifier system is further provided, as shown in fig. 8, including a water inlet valve 220, a filter element 230, a check valve 240, a water flow detector and a controller 250, wherein the water inlet valve 220, the filter element 230 and the check valve 240 are sequentially connected through a pipeline, the water flow detector is disposed on the pipeline, the controller 250 is connected with the water flow detector and the water inlet valve 220, and the controller 250 is configured to perform water leakage detection according to the method described above. Specifically, the controller 250 may employ an original main control board of the water purifier system. The water purifier system may further include a pre-filter 210 disposed at a front end of the inlet valve 220, and the water flow detector may include a front water flow detector which may employ a TDS probe or a flow meter 1 and a rear water flow detector which may employ a pressure switch or a flow meter 2.
According to the water purifier system, water leakage detection is performed by combining data detected by the original water flow detector of the water purifier system, a separate water leakage detection module is not required to be additionally arranged, and the detection cost is reduced by using the traditional water purifier water leakage detection method.
In order to better understand the water purifier system water leakage detection method, apparatus and water purifier system, the following detailed explanation is made with reference to specific embodiments.
In one embodiment, as shown in FIG. 8, the water purifier system diagram includes a pre-filter cartridge 210, a water inlet valve 220, a flow meter 1 or TDS probe, a filter cartridge 230, a check valve 240, a pressure switch or flow meter 2, and a faucet 300. The water purifier system can be divided into two sections: the front section from the inlet valve 220 to the check valve 240 is the check valve, and the rear section from the check valve 240 to the faucet 300 is the check valve. The controller 250 is used to control the inlet valve 220, and the check valve 240 can prevent backflow to ensure the pressure at the rear section of the check valve 240.
The water purifier system is a system capable of respectively discharging purified water and domestic water, and can most comprehensively detect the water leakage condition of each place on the basis of not adding other devices. The clean water is water passing through the pre-filter element 210, the water inlet valve 220, the flowmeter 1 or the TDS probe, the filter element 230, the check valve 240, the pressure switch or the flowmeter, and the water tap 300, and can be directly drunk. The domestic water is water passing through the pre-filter 210, the water inlet valve 220, the flowmeter 1 or TDS probe and the water tap 300, and can be used for washing vegetables and the like.
When the water purifier system is not in the water producing state, the water inlet valve 220 is closed, and when the water tap 300 is closed, no water flows. The specific detection method is shown in fig. 9:
1. the water purifier system is not in water preparation state, if the check valve 240 anterior segment leaks, water between water intaking valve 220 and the check valve 240 can the light leak after a period of time, TDS probe can expose in the air this moment, and the TDS detected value can be close 0, and the TDS value of most running water all is greater than 100, so when TDS value < default 5, can judge that the check valve 240 anterior segment leaks.
2. When the water purifier system is not in a water production state and water leakage occurs at the front section of the check valve 240, the flow meter 1 can detect water flow at one continuous end time and can judge that water leakage occurs at the front section of the check valve 240.
3. The water purifier system detects whether the water tap 300 is turned off through the pressure switch or the flow meter 2, thereby deciding whether water production is required. After the system determines that the required water is in the water making state, the water making speed is determined accordingly, whether the water making quantity is far higher than that of a single water taking quantity normally used by a user or not can be judged according to the water making time or the counting of the flow meter, and therefore whether obvious water leakage occurs at the rear section of the check valve 240 or not is judged. For example, when the single water making time is detected to be greater than the set value 1, it can be considered that the check valve 240 has obvious water leakage.
4. The water purifier system is not in system water state, and when the drippage appeared in the check valve rear end, the pressure that need pass through a period of back check valve 240 rear end could reduce a definite value to make pressure switch detect the low pressure, begin system water this moment, because system water speed is far greater than the speed of drippage, will stop system water in a plurality of seconds, if the condition of the short duration system water of frequently appearing in a period can judge that the drippage appears in the check valve 240 rear end. For example, when the single water making time is less than the set value 2, the number of times of one abnormal water making is increased, and if the number of times of the abnormal water making is greater than the set value 3, it is determined that the back section of the check valve 240 has the water leakage.
When water leakage is detected, the water inlet valve 220 is closed, so that water leakage can be avoided continuously, and a protection effect is achieved. In addition, if the running time of the whole machine of the system is greater than a set value 4, the abnormal times are cleared, and the running time of the whole machine is cleared.
In another embodiment, as shown in FIG. 10, the water purifier system includes a pre-filter cartridge 210, a fill valve 220, a filter cartridge 230, a check valve 240, a pressure switch or flow meter, a faucet 300. The system has no TDS detection function and can only discharge pure water, and because of no TDS probe or no flowmeter 1, whether the front section of the check valve 240 leaks water or not can not be detected, but because the water stored in the pipeline at the front section of the check valve 240 is less, and the water at the rear section of the check valve 240 cannot flow back, the water leakage influence is small, the water leakage at the rear section of the check valve 240 is detected in time, the water leakage amount can be reduced by closing the water inlet valve 220, and a good effect can be achieved. The detection method of this embodiment is the same as the 3, 4 points in the previous embodiment.
Above-mentioned water purifier system can judge whether obvious leaking appears according to continuous system water time to and judge whether the drippage appears according to the frequency of making water, can also detect the water leakage part before the check valve or behind the check valve. By utilizing the existing structure, whether the water purifier leaks or not and the specific water leaking part are detected accurately on the basis of not increasing the hardware cost.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
