本發明係提供一種複合式水質感測裝置及感測方法，尤指利用不同水質感測器、分別感測水質顆粒濃度及離子濃度之感測方法，在水質產生變化時，透過顆粒濃度感測器與離子濃度感測器配合進行水質感測，供準確判斷水質之目的。The invention provides a composite water quality sensing device and a sensing method, in particular, a sensing method for sensing water particle concentration and ion concentration by using different water quality sensors, and sensing the particle concentration when the water quality changes. The instrument is combined with an ion concentration sensor for water quality sensing for accurate water quality purposes.
按，隨著電子科技時代的不斷進步，許多電子、電氣的家電產品問世，提供人們在生活上的舒適與便捷，在日常生活中的衣、食、住、行及娛樂等，透過不同的家電產品，進行快速的處理，減少人工手動的耗時、費工且不完善，而在一般的家電產品中，部分需要連接水源進行作業，如：洗衣機、洗碗機等，利用水流配合清潔液、洗滌劑等進行清洗作業，即可不必動手而將衣物、碗盤餐具等予以清洗乾淨，但在清洗過程中，洗衣機內部的水流因衣物上的灰塵、細屑或清潔液、洗滌劑等影響，造成水質的濁度提高，或者洗碗機內部的水流因碗盤餐具上的食物殘渣、細屑或清潔液、洗滌劑等，亦會導致水質的濁度、顆粒濃度便會提高，而必須透過數次的清水進行洗清的作業，達到將衣物或碗盤餐具等清洗乾淨之目的，以供水質的離子濃度符合檢測標準，則目前在洗衣機或洗碗機中，都會加裝水質感測設備，透過投射光源感測水質後反射接收，藉以感測水質顆粒濃度(水中顆粒 濃度值，如：未溶解之清潔劑、雜質或灰塵或毛髮或衣物毛屑、棉絮等)值，以供判斷水質混濁的情況，再設定洗衣機或洗碗機等家電產品的清洗作業模式；然而現今使用之清潔劑仍持續提升與改良洗淨能力，僅偵測水中之顆粒濃度，並無法偵測出洗衣機或洗碗機運轉過程中清潔劑之殘留。According to the continuous advancement of the electronic technology era, many electronic and electrical home appliances have come out to provide people with comfort and convenience in their daily lives, through clothing, food, accommodation, travel and entertainment in daily life. Products, rapid processing, reducing manual and manual time-consuming, labor-intensive and imperfect, and in general household appliances, some need to connect water source for work, such as: washing machine, dishwasher, etc., using water flow with cleaning fluid, Washing the detergent, etc., it is possible to clean the clothes, dishes, and the like without having to do it, but during the cleaning process, the water inside the washing machine is affected by dust, fines, cleaning liquid, detergent, etc. on the clothes. The turbidity of the water quality is increased, or the water flow inside the dishwasher may cause the turbidity and particle concentration of the water to increase due to the food residue, fines or cleaning liquid, detergent, etc. on the dishes. Washing the water several times to achieve the purpose of cleaning the clothes or dishes, and the ion concentration of the water supply meets the testing standards. In the present washing machine or dishwasher, the water quality sensing devices are installed, receives light through the rear projection sensing reflected quality sensing, thereby sensing the quality particle concentration (particles in water Concentration values, such as: undissolved detergent, impurities or dust or hair or clothing dander, cotton wool, etc., for judging the turbidity of the water, and then setting the cleaning mode of household appliances such as washing machines or dishwashers; The cleaners used today continue to improve and improve the cleaning ability. Only the particle concentration in the water is detected, and the residue of the detergent during the operation of the washing machine or the dishwasher cannot be detected.
若欲偵測水中殘留之清潔劑，可透過檢測固體溶解於水中後產生之離子濃度變化得知；當水中溶有可解離之鹽類例如鹽、汗水、糖、飲料、色素等，以及清潔劑、漂白水或柔軟精時，該溶液即具有導電性，導電能力越高者，即代表融入水中的固體量越多，導電度(Electrical Conductivity，EC)的量測值越高。If you want to detect the residual detergent in the water, you can find out the change of the ion concentration produced by the solid dissolved in water; when the water is dissolved with dissociable salts such as salt, sweat, sugar, beverages, pigments, etc., and detergent In the case of bleaching water or softening, the solution is electrically conductive, and the higher the electrical conductivity, that is, the greater the amount of solids incorporated into the water, the higher the conductivity (Electrical Conductivity, EC).
而所謂水質感測，係針對離子濃度與顆粒濃度等二大類進行感測，其中離子濃度以電極方式感測，可感測水中可溶解物質之濃度(TDS)，而電極感測又可分為直接訊號(即導電度)與比較訊號(如酸鹼度)方式。顆粒濃度即表示水中不可溶解之懸浮顆粒濃度(總懸浮固體TSS)，通常可由濁度感測值推算得之。通常水質的濁度值介於1NTU~10000NTU之間，洗滌家電一般檢測濃度則為濁度值介於100NTU~4000NTU之間，乃依據製造廠商、清潔機具的機型等不同，而有數據上的差別；而水質的離子濃度值為低於1mS/cm度以下，洗滌家電因考慮清潔劑的使用狀況，一般檢測濃度則為導電度介於0.1~1 0mS/cm之間；但一般用以偵測水質感測器，並不能同時偵測水質的顆粒濃度、離子濃度(濁度及導電度)，因濁度感測器係針對水質的顆粒濃度進行偵測，對於水質的離子濃度即無法偵測；至於離子濃度感測器，則是針對水質的離子濃度進行偵測，對於水質的顆粒濃度較不易測得；在實際應用實施時，存在些許缺失與困擾，如：The so-called water quality sensing is based on two categories: ion concentration and particle concentration. The ion concentration is sensed by electrodes, which can sense the concentration of soluble substances in water (TDS), and electrode sensing can be divided into Direct signal (ie conductivity) and comparison signal (eg pH). The particle concentration is the concentration of suspended particles (total suspended solids TSS) which is insoluble in water and is usually estimated from the turbidity sensing value. Generally, the turbidity value of water quality is between 1NTU and 10000NTU, and the general detection concentration of washing appliances is between 100NTU and 4000NTU, which is different according to the manufacturer and the cleaning machine. The difference is that the ion concentration of the water is below 1 mS/cm, and the washing appliance considers the use of the detergent. The general detection concentration is 0.1~1. Between 0mS/cm; but generally used to detect water quality sensors, it is not possible to simultaneously detect the particle concentration and ion concentration (turbidity and conductivity) of water quality, because the turbidity sensor is based on the particle concentration of water quality. Detection, the ion concentration of water quality can not be detected; as for the ion concentration sensor, it is to detect the ion concentration of water quality, the particle concentration of water quality is not easy to measure; in actual application, there are some defects With troubles such as:
(1)顆粒濃度感測器僅偵測水質的顆粒濃度，對於水質的離子濃度即無法偵測，容易造成水質中殘留異物或清潔用的洗滌劑影響水質，此外，可溶解之物質如糖、鹽、咖啡、茶鹼、色素等難以分辨，導致清潔作業不確實。(1) The particle concentration sensor only detects the particle concentration of the water, and the ion concentration of the water is undetectable, which easily causes the residual foreign matter in the water or the detergent used for cleaning to affect the water quality. In addition, the soluble substance such as sugar, Salt, coffee, theophylline, pigments, etc. are difficult to distinguish, resulting in inaccurate cleaning operations.
(2)離子濃度感測器則只偵測水質之離子濃度，對於水質的顆粒濃度並無法偵測，也因為水質中的顆粒濃度值若較高，易造成離子濃度感測器的偵測電極氧化或老化的現象發生，可能導致離子濃度感測器的使用壽命縮短。(2) The ion concentration sensor only detects the ion concentration of the water. The particle concentration of the water is not detectable, and because the particle concentration in the water is higher, it is easy to cause the detection electrode of the ion concentration sensor. The occurrence of oxidation or aging may result in a shortened service life of the ion concentration sensor.
是以，如何解決目前水質偵測之濁度感測器使用時，受到水質感測(顆粒濃度、離子濃度)之限制、影響偵測水質的品質變差之問題與困擾，並造成水質感測器感測效果不正確之缺失及不便，即為從事此行業之相關廠商所亟欲研究改善之方向所在者。Therefore, how to solve the problem of water quality sensing (particle concentration, ion concentration), affecting the quality of the detected water quality, and causing water quality sensing when using the current turbidity sensor for water quality detection The lack of correctness and inconvenience of the sensing effect is the direction that the relevant manufacturers engaged in this industry are eager to study and improve.
故，發明人有鑑於上述之問題與缺失，乃搜集相關資料，經由多方評估及考量，並以從事於此行業累積之多年經驗，經由不斷試作及修改，始設計出此種可同步感測水質之濁度，並依據水質的顆粒濃度(濁度，NTU)，啟用不同感測器，確保感測值的準確度之複合式水質感測裝置及感測方法的發明專利誕生者。Therefore, in view of the above problems and deficiencies, the inventors have collected relevant information, and through multiple assessments and considerations, and through years of experience in the industry, through continuous trial and modification, we have designed this synchronous sensing water quality. The turbidity, and according to the particle concentration of water (turbidity, NTU), the birth of the invention patent of the composite water quality sensing device and the sensing method that enable different sensors to ensure the accuracy of the sensing value.
本發明之主要目的乃在於該水質感測之步驟，係透過控制系統操控第一驅動電路，啟動顆粒濃度感測器開始感測水質之顆粒濃度值(濁度值)，若感測值大於預設值、繼續感測水質之顆粒濃度值，若感測值小於預設值，即由顆粒濃度感測器傳送訊號至控制系統的比較電路、訊號過濾器，透過比較電路與內建參考電壓值，進行比對，而訊號值大於參考電壓值、即顆粒濃度感測器繼續感測水質，若訊號值小於參考電壓值、為利用比較電路操控第二驅動電路，啟動離子濃度感測器開始感測水質之離子濃度、水質之直接訊號(即導電度)與比較訊號(如酸鹼度)，並傳輸訊號至訊號過濾器、訊號處理器，避免離子濃度感測器長時間處於高顆粒濃度水質的感測環境中，達到延長離子濃度感測器使用壽命之目的。The main purpose of the present invention is to perform the step of water quality sensing by controlling the first driving circuit through the control system, and starting the particle concentration sensor to start sensing the particle concentration value (turbidity value) of the water quality, if the sensing value is greater than the pre- Set the value and continue to sense the particle concentration value of the water. If the sensed value is less than the preset value, the particle concentration sensor transmits the signal to the comparison circuit of the control system, the signal filter, and the comparison circuit and the built-in reference voltage value. , the comparison value, and the signal value is greater than the reference voltage value, that is, the particle concentration sensor continues to sense the water quality, if the signal value is less than the reference voltage value, in order to use the comparison circuit to control the second driving circuit, start the ion concentration sensor to start feeling Measure the ion concentration of water, the direct signal (ie conductivity) of the water quality and the comparison signal (such as pH), and transmit the signal to the signal filter and signal processor to avoid the feeling of high concentration of water in the ion concentration sensor for a long time. In the measurement environment, the purpose of prolonging the life of the ion concentration sensor is achieved.
本發明之次要目的乃在於該水質感測裝置，係利用控制系統分別操控第一驅動電路啟動顆粒濃度感測器、操控第二驅動電路啟動離子濃度感測器，依據水質顆粒濃度與預設訊 號值(濁度100NTU)比對，當水質顆粒濃度值(濁度值，可預設為50NTU、30NTU或10NTU等，可依實際使用情況進行調整數據值高低)高於預設值時，係由顆粒濃度感測器持續感測水質濁度，若水質顆粒濃度值低於預設值時，即利用離子濃度感測器感測水質離子濃度，達到依據水質之顆粒濃度(濁度)、離子濃度(總固體溶解量、導電度)不同，利用不同水質感測器進行感測之目的，得到較準確的感測數據。The secondary object of the present invention is that the water quality sensing device controls the first driving circuit to activate the particle concentration sensor and the second driving circuit to activate the ion concentration sensor, respectively, according to the water particle concentration and the preset. News The value (turbidity 100NTU) is compared. When the water particle concentration value (the turbidity value can be preset to 50NTU, 30NTU or 10NTU, etc., the data value can be adjusted according to the actual use) is higher than the preset value. The water concentration turbidity is continuously sensed by the particle concentration sensor. If the water particle concentration value is lower than the preset value, the ion concentration sensor is used to sense the water ion concentration to achieve the particle concentration (turbidity) and ions according to the water quality. The concentration (total solid dissolved amount, conductivity) is different, and different water quality sensors are used for sensing purposes to obtain more accurate sensing data.
為達成上述目的及功效，本發明所採用之技術手段及其構造、實施之方法，茲繪圖就本發明之較佳實施例詳加說明其特徵與功能如下，俾利完全瞭解。In order to achieve the above objects and effects, the technical means, the structure, and the method of the present invention are described in detail.

請參閱第一、二圖所示，係為本發明之流程圖、方塊圖，由圖中所示可以清楚看出，本發明之複合式水質感測方法，係包括控制系統1、水質感測系統2，而其進行水質感測之步驟係：Please refer to the first and second figures, which are flowcharts and block diagrams of the present invention. It can be clearly seen from the figure that the composite water quality sensing method of the present invention includes a control system 1 and water quality sensing.

(100)利用控制系統1之電壓調節器11操控第一驅動電路12，進而啟動水質感測系統2之顆粒濃度感測器21，開始感測水質之顆粒濃度(濁度)。(100) The first drive circuit 12 is operated by the voltage regulator 11 of the control system 1, and then the particle concentration sensor 21 of the water quality sensing system 2 is activated to start sensing the particle concentration (turbidity) of the water quality.
(101)而顆粒濃度感測器21感測水質之顆粒濃度值，判斷顆粒濃度值是否大於預設值(濁度感測值約 介於50度~300度之間，而當濁度值大於50度即屬於高濁度)。(101) The particle concentration sensor 21 senses the particle concentration value of the water quality, and determines whether the particle concentration value is greater than a preset value (the turbidity sensing value is about Between 50 degrees and 300 degrees, and when the turbidity value is greater than 50 degrees, it is high turbidity).
(102)由顆粒濃度感測器21傳送訊號至控制系統1的比較電路13、並執行步驟(103)；且顆粒濃度感測器21亦同步將訊號傳送至訊號處理器23並執行步驟(106)。(102) The signal is transmitted from the particle concentration sensor 21 to the comparison circuit 13 of the control system 1, and the step (103) is performed; and the particle concentration sensor 21 also synchronously transmits the signal to the signal processor 23 and performs the step (106). ).
(103)以供比較電路13接將接收之顆粒濃度感測器21的訊號，予以與收控制系統1的參考電壓值單元14內建參考電壓值，進行比對。(103) The comparator circuit 13 receives the signal of the received particle concentration sensor 21 and compares it with the reference voltage value unit 14 of the control system 1 for comparison.
(104)比較電路13比對顆粒濃度感測器21之訊號值大於參考電壓值(+5V或+3V等)、即執行步驟(101)；而訊號值若小於參考電壓值(例如：0)、即執行步驟(105)。(104) The comparison circuit 13 compares the signal value of the particle concentration sensor 21 with a reference voltage value (+5V or +3V, etc.), that is, performs step (101); and if the signal value is smaller than the reference voltage value (for example, 0) That is, step (105) is performed.
(105)再透過比較電路13操控第二驅動電路15，進而啟動離子濃度感測器22，開始感測水質之離子濃度，並由離子濃度感測器22傳輸訊號至訊號處理器23。(105) The second driving circuit 15 is further controlled by the comparison circuit 13, and then the ion concentration sensor 22 is activated to start sensing the ion concentration of the water quality, and the ion concentration sensor 22 transmits the signal to the signal processor 23.
(106)透過訊號處理器24，判斷顆粒濃度感測器21或離子濃度感測器22運作，並向外輸出訊號以顯示水質感測系統2的作業狀態。(106) The signal processor 24 determines whether the particle concentration sensor 21 or the ion concentration sensor 22 operates, and outputs a signal to display the operation state of the water quality sensing system 2.
上述步驟(101)中，水質之顆粒濃度值的檢測數據，係本發明預設之檢測數據，並非以此限制檢測數據之範圍 ，檢測數據係可依據不同製造廠商、清潔機具機型等，有所變化，均可供本發明變更預設數據應用。In the above step (101), the detection data of the particle concentration value of the water quality is the preset detection data of the present invention, and does not limit the range of the detection data by this. The detection data can be changed according to different manufacturers, cleaning machine models, etc., and can be used to change the preset data application of the present invention.
且上述本發明之水質感測方法，在控制系統1的電壓調節器11，係連接於供電源111，以供應控制系統1所需之電能，且供電源111則可為乾電池、鋰電池、充電電池、蓄電池或外部之市電等，可供控制系統1運作之供電源111。In the above water quality sensing method of the present invention, the voltage regulator 11 of the control system 1 is connected to the power supply 111 to supply the power required by the control system 1, and the power supply 111 can be a dry battery, a lithium battery, and a charging device. A power supply 111 for controlling the operation of the system 1 by a battery, a battery, or an external utility power.
而水質感測系統2之顆粒濃度感測器21、離子濃度感測器22，係分別感測水質之顆粒濃度〔濁度感測範圍設定介於50NTU~300NTU(洗衣機)或100NTU~3000NTU(洗碗機)〕，且水質顆粒濃度為水中無法溶解之懸浮顆粒濃度(總懸浮固體TSS)，依水中懸浮顆粒濃度的數量多寡，決定水質之顆粒濃度值是否大於或小於預設值(可預設為水質濁度50NTU、30NTU或10NTU等，並可依實際使用情況進行調整數據值高低)，再啟動顆粒濃度感測器21或離子濃度感測器22，進行水質的顆粒濃度、離子濃度之感測：並在水質顆粒濃度高於預設值(濁度大於50NTU)時，啟動顆粒濃度感測器21進行感測水質；且當水質顆粒濃度(濁度小於50NTU)低於預設值時，則啟動離子濃度感測器22進行感測水質，可以避免在水質顆粒濃度(濁度大於50NTU)過高，則啟動離子濃度感測器22，即不致造成離子濃度感測器22 因處在水質顆粒濃度高(濁度大於50NTU〔亦可為30NTU或10NTU等，並可依實際使用情況進行調整數據值高低〕之低導電度、高酸鹼度等)的環境中，而氧化或老化，確保離子濃度感測器22的使用壽命會不縮短，因水中可解離的鹽類，使水質具有導電性，而導電能力越高，導電度的量測值越高，導電值常用單位包括：導電度(EC)、導電因子(CF)與總固體溶解量(TDS)，且導電度與導電因子之間的換算：1mS/cm(EC)=10CF。The particle concentration sensor 21 and the ion concentration sensor 22 of the water quality sensing system 2 respectively sense the particle concentration of the water quality (the turbidity sensing range is set between 50 NTU and 300 NTU (washing machine) or 100 NTU~3000 NTU (washing) Dish machine)], and the water particle concentration is the concentration of suspended particles in the water (total suspended solids TSS), depending on the amount of suspended particles in the water, determine whether the water particle concentration value is greater than or less than the preset value (preset The water turbidity is 50NTU, 30NTU or 10NTU, etc., and the data value can be adjusted according to the actual use condition. Then, the particle concentration sensor 21 or the ion concentration sensor 22 is activated to perform the particle concentration and the ion concentration of the water. Measurement: and when the water particle concentration is higher than a preset value (turbidity is greater than 50 NTU), the particle concentration sensor 21 is activated to sense the water quality; and when the water particle concentration (turbidity is less than 50 NTU) is lower than a preset value, Then, the ion concentration sensor 22 is activated to sense the water quality, and the ion concentration sensor 22 is activated when the water particle concentration (turbidity greater than 50 NTU) is too high, that is, the ion concentration sensor 22 is not caused. Oxidation or aging in an environment where the water concentration is high (the turbidity is greater than 50 NTU (may be 30 NTU or 10 NTU, etc., and the data value can be adjusted according to the actual use), low conductivity, high pH, etc.) To ensure that the service life of the ion concentration sensor 22 will not be shortened, the water can be electrically conductive due to the dissociable salts in the water, and the higher the conductivity, the higher the conductivity measurement value, and the common units of the conductivity value include: Conductivity (EC), conductivity (CF) and total solids dissolved (TDS), and conversion between conductivity and conductivity: 1 mS/cm (EC) = 10 CF.
至於導電度與總固體溶解量之間的換算，則因各國家、地域而有不同通常，例如：1mS/cm(EC)=500ppm(美國)。1mS/cm(EC)=640ppm(歐洲)。1mS/cm(EC)=700ppm(澳洲)。As for the conversion between the conductivity and the total solid dissolved amount, it varies depending on each country and region, for example, 1 mS/cm (EC) = 500 ppm (USA). 1 mS/cm (EC) = 640 ppm (Europe). 1 mS/cm (EC) = 700 ppm (Australia).
以上各種換算數據僅供參考，並非用以限制本案之技術或申請專利範圍，實際數據將依實際使用時之條件變化。The above various conversion data are for reference only and are not intended to limit the technical or patent application scope of the case, and the actual data will vary according to the conditions in actual use.

而透過上述複合式感測裝置，供安裝於各種用水之家電產品，如：洗衣機或洗碗機等，透過控制系統1之電壓調節器11，驅動第一驅動電路12啟動水質感測系統2之顆粒濃度感測器21，利用顆粒濃度感測器21進行水質感測，在感測水質的顆粒濃度大於預設值{水質濁度〔介於50NTU~300NTU(家用洗衣機)或100NTU~3000NTU(洗碗機)}，濁度高於50NTU，即屬高濁度}時，顆粒濃度感測器21即持續感測水質的混濁度；而當顆粒濃度感測器21，進行感測水質中的顆粒濃度小於預設值(水質之濁度低於50NTU、30NTU或10NTU等，並可依實際使用情況進行調整數據值高低)時，係感測水質中不可溶解於水中之物質〔懸浮顆粒濃度(總懸浮固體TSS)〕之含量(如：洗滌液、清潔劑、清潔液、清潔粉末或衣物毛屑、纖維絲、毛球或塵屑、毛髮等)之濁度， 則發出訊號至比較電路13，比較電路13並同時取得參考電壓單元14之預設電壓值，透過預設電壓值與訊號進行比對〔該比較電路13所應用之參考電壓值若為0或VCC(即系統供電的最大值，例如+5V或+3V等)係代表離子濃度感測器22為處於常開狀態(always on)或者常閉(always off)之狀態〕，且由比較電路13配合電壓調節器11，一起驅動第二驅動電路15，再由第二驅動電路15啟動離子濃度感測器22，即利用離子濃度感測器22繼續偵測水質的離子濃度，離子濃度感測器22係以電極方式感測水質之離子濃度(可溶解於水中之物質〔水中清潔液、清潔劑等殘留量)的總固體溶解量或導電度；而離子濃度感測器22的電極感測可分為直接訊號(如：水質中之導電度)、比較訊號(如：水質中之酸鹼度)；並在水質感測系統2的顆粒濃度感測器21、離子濃度感測器22運作時，均會分別傳送訊號至訊號處理器23(亦可將訊號先傳送至訊號過濾器231，再由訊號過濾器231傳送至訊號處理器23)，以透過訊號處理器23判斷，所接收的訊號是顆粒濃度感測器21或離子濃度感測器22之訊號，以辨別水質顆粒濃度(水質濁度，一般家用洗衣機的濁度數值為50~300NTU；洗碗機為100~3000NTU、水質之導電度偵測範圍介於0.1ms/cm~10ms/cm)的情況，再將訊號向外傳輸至外部預設主 機，由預設主機面板顯示水質感測系統2的運作情況，可控制清潔用水的潔淨程度保持在一定的範圍以內(水質濁度低於50NTU、30NTU或10NTU等，並可依實際使用情況進行調整數據值高低)。And through the above-mentioned composite sensing device, for installing household appliances such as washing machines or dishwashers, the first driving circuit 12 is activated by the voltage regulator 11 of the control system 1 to activate the water quality sensing system 2 The particle concentration sensor 21 uses the particle concentration sensor 21 to perform water quality sensing, and the particle concentration in the sensing water quality is greater than a preset value {water turbidity [between 50 NTU and 300 NTU (home washing machine) or 100 NTU~3000 NTU (washing) The bowling machine)}, when the turbidity is higher than 50 NTU, that is, the high turbidity}, the particle concentration sensor 21 continuously senses the turbidity of the water quality; and when the particle concentration sensor 21 performs the sensing of the particles in the water quality When the concentration is less than the preset value (the turbidity of the water is lower than 50NTU, 30NTU or 10NTU, and the data value can be adjusted according to the actual use), it is the substance that is insoluble in water in the water quality [suspension particle concentration (total The turbidity of the content of suspended solids TSS), such as: washing liquid, detergent, cleaning solution, cleaning powder or clothing dander, filament, hair ball or dust, hair, etc. Then, the signal is sent to the comparison circuit 13, and the comparison circuit 13 obtains the preset voltage value of the reference voltage unit 14 and compares it with the signal through the preset voltage value. The reference voltage value applied by the comparison circuit 13 is 0 or VCC. (ie, the maximum value of the system power supply, such as +5V or +3V, etc.) means that the ion concentration sensor 22 is in a normally on state or an always off state, and is matched by the comparison circuit 13 The voltage regulator 11 drives the second driving circuit 15 together, and then the second driving circuit 15 activates the ion concentration sensor 22, that is, the ion concentration sensor 22 continues to detect the ion concentration of the water source, and the ion concentration sensor 22 The total ion dissolved amount or conductivity of the water source (the amount of the substance that can be dissolved in water (the amount of the cleaning liquid, the detergent, etc.) in the water is sensed by the electrode; and the electrode sensing of the ion concentration sensor 22 can be divided. For direct signals (eg, conductivity in water quality), comparison signals (eg, pH in water quality); and when the particle concentration sensor 21 and the ion concentration sensor 22 of the water quality sensing system 2 operate, Send signal to the signal separately The processor 23 (which can also transmit the signal to the signal filter 231 and then to the signal processor 23 via the signal filter 231) to determine by the signal processor 23 that the received signal is the particle concentration sensor 21 or The signal of the ion concentration sensor 22 to distinguish the water particle concentration (water turbidity, the turbidity value of the general household washing machine is 50~300 NTU; the dishwasher is 100~3000 NTU, and the conductivity detection range of the water quality is 0.1 ms) /cm~10ms/cm), then the signal is transmitted to the external preset master The machine displays the operation of the water quality sensing system 2 by the preset host panel, and can control the cleanliness of the cleaning water to be within a certain range (the water turbidity is lower than 50NTU, 30NTU or 10NTU, etc., and can be carried out according to actual use conditions) Adjust the data value).
