Describe with reference to the accompanying drawings according to the dirty detection method of the inner container of electric water heater of the embodiment of the present invention and the electric heater adopting this detection method.
First the dirty detection method of the inner container of electric water heater of the embodiment of the present invention is described.Fig. 1 is the flow chart of the dirty detection method of inner container of electric water heater according to an embodiment of the invention, and as shown in Figure 1, this detection method comprises the following steps:
S1, detects the current water quality information of water in inner container of electric water heater.
Wherein, water quality information comprises turbidity and/or the electrical conductivity of water in such as inner bag, also can for the concentration of certain particle comprised in water in other water quality information such as inner bag.For turbidity and electrical conductivity, can by being arranged on the turbidity and electrical conductivity that turbidity transducer in inner container of electric water heater and conductivity sensor carry out detecting to obtain water in current water quality information and inner bag respectively.
S2, judges the degree of fouling of inner bag according to current water quality information and initial water quality information.
It should be noted that, initial water quality information can for the water quality information determined when electric heater runs for the first time, in addition, initial water quality information can upgrade accordingly along with the change of water quality in inner bag, and the acquisition for initial water quality information will be described in detail in specific embodiment below.
Particularly, numerical example corresponding to water quality information can be set as the scope of AD value or threshold value, and then according to current water quality information and the initial relation of water quality information and the degree of fouling of the satisfied scope that arranges or threshold decision inner bag, will be described in following specific embodiment the concrete deterministic process of inner bag degree of fouling.
S3, if the degree of fouling of inner bag meets cleaning condition, then reports to the police.
Such as, the relation of current water quality information and initial water quality information meets setting model, when current water quality information is greater than threshold value, judge that the degree of fouling of inner bag meets cleaning condition, can think that inner bag is messy, need to clean, and then carry out alarm, such as pointed out by sound and/or display, thus user can recognize that the dirty needs of inner bag clean in time, ensure that use water is healthy, in addition, can avoid carrying out blowdown or cleaning to inner bag to evening too early or excessively, reduce the wasting of resources.
In addition, consider that in inner bag, current and temperature are on the impact of water quality testing data, below to detect turbidity and the electrical conductivity of water in inner bag, to according to current, water temperature and current water quality information and initial water quality information, the dirty testing process of inner bag is described in detail.
Particularly, the turbidity of water in inner bag can be detected by the turbidity transducer arranged in inner container of electric water heater, and detect electrical conductivity of water in inner bag by conductivity sensor, usually, turbidity transducer is connected with the AD port of the controller of electric heater with the detection input of conductivity sensor, is changed by D/A, obtains the AD value of different situations, controller can adopt 8 single-chip microcomputers, and the scope of AD value is between 0-255.For the detection of turbidity, turbidity transducer can obtain the detected value of turbidity by the situation of the light of water in inner bag, when light is through certain water, the transit dose of light depends on the muddy degree of water, and water is more muddy, then through light fewer, otherwise the light passed through is more.The optical receiving end of turbidity transducer by through luminous intensity be converted to corresponding size of current, turbidity current signal is converted to the voltage signal of 0V-5V through suitable resistance, the A/D converter of recycling controller carries out sampling processing, thus obtain current turbidity, the AD value of turbidity is larger, then the turbidity of water is less, otherwise, the AD value of turbidity is less, then the turbidity of water is larger.
At the use initial stage of electric heater, the AD value that the AD value of turbidity detecting the water of the inner bag obtained such as is set to S-VALUE and electrical conductivity is such as set to D-VALUE, and is stored in controller by S-VALUE and D-VALUE.At the use initial stage, turbidity AD value is larger, and electrical conductivity AD value is smaller, along with the passing of electric heater service time, inner bag is more and more dirty, in inner bag, water is also dirty, the AD value of turbidity and electrical conductivity also changes, such as turbidity increases, and conductivity value increases, detect the turbidity such as S2 and electrical conductivity D2 of water in inner bag in real time, and the currency of detection and initial value are compared, thus the soiled condition of inner bag can be judged, and the blowdown of pointing out user to carry out inner bag and cleaning treatment.
First, when user uses electric heater for the first time, detect and to record in inner bag the water quality information of water and the turbidity of water and electrical conductivity, as initial water quality information.Particularly, in order to ensure the accuracy of detected parameters, when the first task of electric heater, detect the temperature of water in inner bag, when in inner bag, the temperature of water is more than or equal to the first preset temperature and current detected, in record inner bag, the turbidity of water and electrical conductivity are as the first turbidity and the first electrical conductivity, and when the temperature of water in inner bag is more than or equal to the second preset temperature and current do not detected in Preset Time, in record inner bag, the turbidity of water and electrical conductivity are as the second turbidity and the second electrical conductivity, wherein, second preset temperature is greater than the first preset temperature, and then determine initial water quality information according to the first turbidity and the first electrical conductivity and the second turbidity and the second electrical conductivity.Such as, when the first turbidity is less than the second turbidity, namely when the AD value of the first turbidity is more than or equal to the AD value of the second turbidity, first turbidity is initial turbidity degree, otherwise the second turbidity is initial turbidity degree, when the first electrical conductivity is more than or equal to the second electrical conductivity, second electrical conductivity is initial conductivity, otherwise the first electrical conductivity is initial conductivity.
As a specific embodiment, as shown in Figure 2, the deterministic process of initial water quality information comprises the following steps:
S100, Real-time Collection water temperature data.
S101, judges whether water temperature is more than or equal to the first preset temperature.
Such as, judge whether the temperature of water in the inner bag that detects is more than or equal to 20 DEG C, the detection impact of usual water temperature on turbidity is little, the detection of electrical conductivity can water temperature 20 DEG C or 25 DEG C time carry out.If water temperature is more than or equal to preset temperature, then enter step S102, otherwise return step S100.
S102, detects whether have current.
Such as, judge that user has useless water by water flow sensing unit, if there are current, then enter step S103, otherwise continue this step.
S103, records the turbidity of water and the AD value of electrical conductivity in inner bag respectively.
Such as, S0 and D0 is set to respectively.
S104, judges whether water temperature is more than or equal to the second preset temperature.
If water temperature is more than or equal to the second preset temperature such as 50 DEG C, enters step S105, otherwise continue this step.
S105, judges whether have current in Preset Time.
If Preset Time does not have current in such as 5 minutes, then enter step S106.In other words, in order to avoid water temperature and current are on the impact of detected value, when temperature be more than or equal to 50 DEG C and meet within 5 minutes, do not have water to enter inner bag time, enter step S106.
S106, records the turbidity of water in current inner bag and the AD value of electrical conductivity respectively.
Such as, S1 and D1 is designated as.And then determine initial water quality information and initial turbidity degree and initial conductivity according to S0, D0 and S1, D1.
S107, judges whether to meet S0 >=S1.
The AD value being about to turbidity and the electrical conductivity detected compares respectively, if S0 is more than or equal to S1, then enters step S108, otherwise, enter step S109.
S108, is stored in S0 in memory as initial turbidity degree.
I.e. S-VALUE=S0.
S109, is stored in S1 in memory as initial turbidity degree.
I.e. S-VALUE=S1.
S110, judges whether the AD value of electrical conductivity meets D0 >=D1.
If D0 is more than or equal to D1, then enter step S111, otherwise enter step S112.
S111, to be stored in D0 in memory as initial conductivity.
I.e. D-VALUE=D0.
S112, to be stored in D1 in memory as initial conductivity.
I.e. D-VALUE=D1.
By above-mentioned steps, thus initial water quality information can be determined.Further, after electric heater uses for the first time, the turbidity of water and electrical conductivity in the water quality information of water and current water quality information such as inner bag in the inner bag of real-time detection user follow-up use electric heater, and constantly compare with the water quality information obtained for the first time, and then judge the soiled condition of inner bag, when the condition is satisfied, carry out alarm/tip user and carry out inner bag cleaning.Particularly, in order to avoid the flowing of water is on the impact detecting data, in the follow-up use procedure of electric heater, when water temperature is greater than the first preset temperature such as 20 DEG C and does not have current in Preset Time such as 5 minutes, detect the current turbidity obtaining water in inner bag and electrical conductivity respectively, the AD value of such as turbidity and electrical conductivity is designated as S2 and D2 respectively, and S2 is stored in the S2-VALUE unit of memory, and D2 is stored in the D2-VALUE unit of memory, and then the water quality information of water in current water quality information and inner bag and initial water quality information are compared.
Particularly, judge in inner bag, whether the current turbidity of water is less than initial turbidity degree, compare by the AD value S2-VALUE of current turbidity and the AD value S-VALUE of initial turbidity degree, judge whether AD value meets S2-VALUE>S-VALUE, if current turbidity is less than initial turbidity degree, illustrate that in inner bag, the turbidity of water is little, then initial turbidity degree is updated to current turbidity and S-VALUE=S2-VALUE, and judge that in inner bag, whether electrical conductivity of water is more than or equal to initial conductivity, namely carries out the judgement of electrical conductivity of water further; If current conductivity is more than or equal to initial conductivity, illustrate that the ion concentration of water in inner bag increases, then when current conductivity is greater than preset alarm electrical conductivity, judge that the degree of fouling of inner bag meets cleaning condition, such as, when the AD value D2-VALUE of current conductivity is greater than 150, the degree of fouling of inner bag meets cleaning condition, then carry out alarm.If when current conductivity is less than initial conductivity and D2-VALUE<D-VALUE, illustrate that turbidity and the electrical conductivity of inner bag are all smaller, water quality in inner bag is also relatively good, then initial conductivity is updated to current conductivity and D-VALUE=D2-VALUE, thus can ensure according to the muddy angle value of the change real-time update of water quality in inner bag and conductivity value, and again detect the current water quality information of water in inner bag, and then according to said process, the current water quality information again detected and the initial water quality information after upgrading are compared.
In addition, if current turbidity is more than or equal to initial turbidity degree, the AD value of the current turbidity namely detected is less than or equal to the AD value of initial turbidity degree, illustrate that the turbidity of water in inner bag becomes large, then judge the affiliated turbidity scope of initial turbidity degree further, and each turbidity scope arranges corresponding warning turbidity, when current turbidity is more than or equal to preset alarm turbidity corresponding to turbidity scope belonging to initial turbidity degree, namely when the AD value of current turbidity is less than or equal to the AD value of preset alarm turbidity, judge that the degree of fouling of inner bag meets cleaning condition.
In one particular embodiment of the present invention, the corresponding form according to the initial turbidity degree preset of a specific embodiment of the present invention and the AD value of initial conductivity and preset alarm turbidity such as S-BUZZER is illustrated in figure 3.According to the difference of the AD value of initial water quality information, be divided into five intervals, wherein, alarm is carried out, particularly, in the first interval: the value of S_VALUE is in 0 ~ 50 scope when the AD value of initial conductivity is greater than 150, when the value of S2_VALUER is less than or equal to 10, then carry out alarm; If when the value of S2_VALUE is greater than 10, then return, continue to detect in real time.Interval second: the value of S_VALUE, in 50 ~ 100 scopes, when the value of S2_VALUE is less than 20, then carries out alarm; If the value of S2_VALUE is greater than 20, then return, continue to detect in real time.Interval the 3rd: the value of S_VALUE, in 100 ~ 150 scopes, when the value of S2_VALUE is less than 50, then carries out alarm; If the value of S2_VALUE is greater than 50, then return, continue to detect in real time.Interval the 4th: the value of S_VALUE, in 150 ~ 200 scopes, when the value of S2_VALUE is less than 60, then carries out alarm; If the value of S2_VALUE is greater than 60, then return, continue to detect in real time.Interval the 5th: the value of S_VALUE, in 200 ~ 250 scopes, when the value of S2_VALUE is less than 70, then carries out alarm; If the value of S2_VALUE is greater than 70, then return, continue to detect in real time.

At the use initial stage of electric heater 100, the AD value that the AD value of turbidity detecting the water of the inner bag 10 obtained such as is set to S-VALUE and electrical conductivity is such as set to D-VALUE, and S-VALUE and D-VALUE is stored in controller 40.At the use initial stage, turbidity AD value is larger, and electrical conductivity AD value is smaller, along with the passing of electric heater 100 service time, inner bag 10 is more and more dirty, in inner bag 10, water is also dirty, the AD value of turbidity and electrical conductivity also changes, such as turbidity increases, and conductivity value increases, detect the turbidity such as S2 and electrical conductivity D2 of water in inner bag 10 in real time, the currency of detection and initial value compare by controller 40, thus the soiled condition of inner bag 10 can be judged, and the blowdown of pointing out user to carry out inner bag 10 and cleaning treatment.
First, when user uses electric heater 100 for the first time, detect and to record in inner bag 10 water quality information of water and the turbidity of water and electrical conductivity, as initial water quality information.Particularly, in order to ensure the accuracy of detected parameters, when the first task of electric heater 100, when in inner bag 10, the temperature of water is more than or equal to the first preset temperature and current detected, controller 40 records the turbidity of water in inner bag 10 and electrical conductivity as the first turbidity and the first electrical conductivity, and when in inner bag 10, the temperature of water is more than or equal to the second preset temperature and current do not detected in Preset Time, in record inner bag 10, the turbidity of water and electrical conductivity are as the second turbidity and the second electrical conductivity, and determine initial water quality information according to the first turbidity and the first electrical conductivity and the second turbidity and the second electrical conductivity, wherein, second preset temperature is greater than the first preset temperature.Such as, when the first turbidity is less than the second turbidity, namely when the AD value of the first turbidity is more than or equal to the AD value of the second turbidity, controller 40 is using the first turbidity as initial turbidity degree, otherwise the second turbidity is initial turbidity degree, when the first electrical conductivity is more than or equal to the second electrical conductivity, controller 40 is using the second electrical conductivity as initial conductivity, otherwise the first electrical conductivity is initial conductivity.
By said process, thus controller 40 can determine initial water quality information.Further, after electric heater 100 uses for the first time, by water quality information and the current water quality information of water in the inner bag 10 of the Water quality detector 20 follow-up use of detection user in real time electric heater 100, turbidity and the electrical conductivity of water in inner bag 10 is such as detected respectively by turbidity transducer 201 and conductivity sensor 202, and constantly compare with the water quality information obtained for the first time, and then controller 40 judges the soiled condition of inner bag 10, when the condition is satisfied, control alarm 30 carries out alarm/tip user and carries out inner bag cleaning.Particularly, in order to avoid the flowing of water is on the impact detecting data, in the follow-up use procedure of electric heater 100, when water temperature is greater than the first preset temperature such as 20 DEG C and does not have current in Preset Time such as 5 minutes, the current turbidity and electrical conductivity that obtain water in inner bag 10 is detected respectively by turbidity transducer 201 and conductivity sensor 202, and then the turbidity that obtains of controller 40 and the AD value of electrical conductivity are designated as S2 and D2 respectively, and S2 is stored in the S2-VALUE unit of memory, and D2 is stored in the D2-VALUE unit of memory, and then the water quality information of water in current water quality information and inner bag and initial water quality information are compared.
Particularly, controller 40 judges in inner bag, whether the current turbidity of water is less than initial turbidity degree, compare by the AD value S2-VALUE of current turbidity and the AD value S-VALUE of initial turbidity degree, judge whether AD value meets S2-VALUE>S-VALUE, if current turbidity is less than initial turbidity degree, illustrate that the turbidity of water in inner bag 10 is little, then initial turbidity degree is updated to current turbidity and S-VALUE=S2-VALUE by controller 40, and judge in inner bag, whether electrical conductivity of water is more than or equal to initial conductivity further, namely the judgement of electrical conductivity of water is carried out, if current conductivity is more than or equal to initial conductivity, illustrate that the ion concentration of water in inner bag increases, then when current conductivity is greater than preset alarm electrical conductivity, controller 40 judges that the degree of fouling of inner bag 10 meets cleaning condition, such as, when the AD value D2-VALUE of current conductivity is greater than 150, the degree of fouling of inner bag 10 meets cleaning condition, then control alarm 30 and carry out alarm.If when current conductivity is less than initial conductivity and D2-VALUE<D-VALUE, illustrate that turbidity and the electrical conductivity of inner bag 10 are all smaller, water quality in inner bag 10 is also relatively good, then initial conductivity is updated to current conductivity and D-VALUE=D2-VALUE by controller 40, thus can ensure according to the muddy angle value of the change real-time update of water quality in inner bag 10 and conductivity value, and again detect the current water quality information of water in inner bag, and then the current water quality information again detected and the initial water quality information after upgrading are compared according to said process by Water quality detector 20.
In addition, if controller 40 judges that current turbidity is more than or equal to initial turbidity degree, the AD value of the current turbidity namely detected is little or equal the AD value of initial turbidity degree, illustrate that the turbidity of water in inner bag becomes large, then controller 40 judges the affiliated turbidity scope of initial turbidity degree further, wherein, each turbidity scope arranges corresponding warning turbidity, when current turbidity is more than or equal to preset alarm turbidity corresponding to turbidity scope belonging to initial turbidity degree, namely when the AD value of current turbidity is less than or equal to the AD value of preset alarm turbidity, controller 40 judges that the degree of fouling of inner bag 10 meets cleaning condition, then control alarm 20 and carry out alarm, thus user can carry out blowdown or the cleaning treatment of electric heater 100 further, ensure that use water is healthy.
Under normal circumstances, the AD value of turbidity can not be greater than 255, even because the water that water quality is poor, consider the refraction of water, AD value also can not more than 255, if S-VALUE is more than or equal to 255, then may turbidity transducer or other circuit malfunctions, then controller 40 controls alarm 20 and carries out alarm.
