Description
一般而言本發明係關於一種淨水器,特定而言本發明係關於一種使用濾材而使原水成為淨水之淨水器。In general, the present invention relates to a water purifier, and more particularly to a water purifier that uses a filter material to make raw water a clean water.
先前,淨水器中有以濾材過濾原水而使之成為淨水,或使原水中所含之雜質沈澱而使原水成為淨水者。向淨水器供給之原水之濁度並非固定,例如存在若流通原水之供水管之內壁剝離等則會導致原水之濁度突發性地變大之情形。又,有時因颱風或大雨等導致原水之濁度暫時變大。Previously, in the water purifier, the raw water was filtered with a filter material to make it pure water, or the impurities contained in the raw water were precipitated to make the raw water a clean water. The turbidity of the raw water supplied to the water purifier is not fixed. For example, if the inner wall of the water supply pipe through which the raw water flows is peeled off, the turbidity of the raw water suddenly increases. Moreover, the turbidity of the raw water may temporarily become large due to typhoon or heavy rain.
例如,日本專利特開2002-58907號公報中記載有一種串列配置有兩段使原水中之懸浮物質凝聚沈澱之凝聚沈澱裝置之凝聚沈澱系統。該凝聚沈澱系統中設置有可根據原水之濁度來選擇性地於一段處理與兩段處理之間進行切換之旁路管線。該凝聚沈澱系統中,於原水之濁度較高之情形時,進行藉由兩段凝聚沈澱裝置而處理原水之兩段處理。另一方面,於原水之濁度較低之情形時,進行藉由一段凝聚沈澱裝置而處理原水之一段處理。For example, JP-A-2002-58907 discloses a coagulation sedimentation system in which two stages of a coagulation sedimentation apparatus for coagulation and precipitation of suspended matter in raw water are arranged in series. The coagulation sedimentation system is provided with a bypass line that can selectively switch between a process and a two-stage process according to the turbidity of the raw water. In the coagulation sedimentation system, when the turbidity of the raw water is high, two treatments of treating the raw water by the two-stage coagulation sedimentation apparatus are performed. On the other hand, in the case where the turbidity of the raw water is low, a treatment of one section of the raw water by a coagulation sedimentation device is performed.
然而,如日本專利特開2002-58907號公報中所記載之凝聚沈澱系統般,為使原水中之懸浮物質凝聚沈澱而使原水成為淨水,需要花費時間。又,需要用以配置沈澱凝聚系統之較大場所。因此,於家庭等中使相對少量之原水成為淨水之情形時難以使用凝聚沈澱裝置。However, in the case of the coagulation sedimentation system described in Japanese Laid-Open Patent Publication No. 2002-58907, it takes time to make the raw water become purified water by causing the suspended matter in the raw water to aggregate and precipitate. Also, there is a need for a larger location to configure the precipitation coacervation system. Therefore, it is difficult to use a coagulation sedimentation apparatus when a relatively small amount of raw water is used as clean water in a home or the like.
因此,於家庭中獲得淨水之情形時,考慮例如將該凝聚沈澱系統之兩段凝聚沈澱裝置分別替換為濾材。Therefore, in the case of obtaining purified water in the home, it is considered to replace, for example, the two-stage coagulation sedimentation apparatus of the coagulation sedimentation system with a filter medium.
然而,於將上述凝聚沈澱系統之兩段凝聚沈澱裝置分別替換為濾材之情形時,當於原水之濁度較大時選擇兩段處理時,濁度較大之原水通過濾材。However, when the two-stage coagulation sedimentation apparatus of the above-described coagulation sedimentation system is replaced with a filter medium, when the two-stage treatment is selected when the turbidity of the raw water is large, the raw water having a large turbidity passes through the filter medium.
如上所述,若濁度較大之水通過濾材,則容易發生濾材之堵塞。若發生濾材之堵塞,則濾材之淨水性能下降。尤其是若濁度大於通常之原水之濁度的原水突發性地流入濾材中,則僅可於短於根據通常之濾材之使用狀況所預測之濾材之壽命、即標準之濾材之可使用期間的期間使用濾材。As described above, if water having a large turbidity passes through the filter medium, clogging of the filter material is likely to occur. If the clogging of the filter material occurs, the water purification performance of the filter material is lowered. In particular, if the raw water having a turbidity greater than the turbidity of the normal raw water suddenly flows into the filter medium, it can be used only for a period shorter than the life of the filter medium predicted according to the use condition of the usual filter medium, that is, the usable period of the standard filter medium. Use a filter material during the period.
因此,本發明之目的在於提供一種可防止由突發性之原水之渾濁所導致之濾材之淨水性能之下降的淨水器。Accordingly, it is an object of the present invention to provide a water purifier which can prevent a decrease in the water purification performance of a filter material caused by turbidity of sudden raw water.
本發明之淨水器包含流水路、濾材、濁度偵測部及切換部。流水路係用以使水流通。濾材係配置於流水路中,使原水通過而成為淨水。濁度偵測部係偵測流水路中所流通之原水之濁度。切換部係於流水路中所流通之水通過濾材之過濾狀態、與通過流水路之水未通過濾材之非過濾狀態之間進行切換。The water purifier of the present invention includes a flow path, a filter medium, a turbidity detecting unit, and a switching unit. The flow path is used to circulate water. The filter material is disposed in the flow channel to pass the raw water and become purified water. The turbidity detecting unit detects the turbidity of the raw water flowing through the flowing water path. The switching unit switches between a state in which the water flowing through the flow path passes through the filter medium and a non-filtered state in which the water passing through the flow path does not pass through the filter medium.
切換部構成為:於由濁度偵測部所偵測之原水之濁度為特定濁度以下之情形時,切換為過濾狀態,於由濁度偵測部所偵測之原水之濁度大於特定濁度之情形時,切換為非過濾狀態。The switching unit is configured to switch to a filtered state when the turbidity of the raw water detected by the turbidity detecting unit is below a specific turbidity, and the turbidity of the raw water detected by the turbidity detecting unit is greater than In the case of a specific turbidity, it switches to the non-filtering state.
於由濁度偵測部所偵測之原水之濁度為特定濁度以下之情形時,切換部將淨水器切換為過濾狀態,藉此流水路中所流通之原水通過濾材而成為淨水。When the turbidity of the raw water detected by the turbidity detecting unit is equal to or less than a specific turbidity, the switching unit switches the water purifier to a filtered state, whereby the raw water flowing through the flow path passes through the filter material to become purified water. .
另一方面,於由濁度偵測部所偵測之原水之濁度大於特定濁度之情形時,切換部將淨水器切換為非過濾狀態,藉此通過流水路之水不通過濾材。On the other hand, when the turbidity of the raw water detected by the turbidity detecting unit is larger than the specific turbidity, the switching unit switches the water purifier to the non-filtering state, whereby the water passing through the flowing water does not pass through the filter.
如上所述,濁度大於特定濁度之原水不通過濾材,藉此即便濁度較大之原水突發性地流入淨水器內,亦可防止由於濁度較大之原水而導致濾材堵塞。As described above, the raw water having a turbidity greater than a specific turbidity does not pass through the filter material, so that even if the raw water having a large turbidity suddenly flows into the water purifier, the filter material can be prevented from being clogged due to the raw water having a large turbidity.
藉此,可提供一種可防止由突發性之原水之渾濁所導致之濾材之淨水性能之下降的淨水器。Thereby, it is possible to provide a water purifier which can prevent a decrease in the water purification performance of the filter medium caused by the turbidity of the sudden raw water.
本發明之淨水器較佳為包含控制切換部之控制部。控制部控制切換部,以使得於由濁度偵測部所偵測之原水之濁度為特定濁度以下之情形時,切換為過濾狀態,於由濁度偵測部所偵測之原水之濁度大於特定濁度之情形時,切換為非過濾狀態。The water purifier of the present invention preferably includes a control unit that controls the switching unit. The control unit controls the switching unit to switch to the filtered state when the turbidity of the raw water detected by the turbidity detecting unit is below a specific turbidity, and the raw water detected by the turbidity detecting unit When the turbidity is greater than the specific turbidity, it switches to the non-filtering state.
藉此,可使用簡單構成之切換部,準確地於過濾狀態與非過濾狀態之間進行切換。Thereby, it is possible to switch between the filtered state and the non-filtered state accurately using the switching unit having a simple configuration.
本發明之淨水器較佳為包含用以蓄積原水之蓄積部。蓄積部較佳為配置於流水路中藉由濁度偵測部偵測濁度之位置與濾材之間。The water purifier of the present invention preferably includes an accumulating portion for accumulating raw water. Preferably, the accumulating portion is disposed between the position where the turbidity detecting portion detects the turbidity and the filter medium in the flowing water path.
有時於利用濁度偵測部偵測濁度與利用切換部切換為非過濾狀態之間需要花費時間。因此,藉由於流水路中之利用濁度偵測部偵測濁度之位置與濾材之間配置蓄積部,而於至利用濁度偵測部偵測出濁度之水通過濾材為止之間,暫時蓄積於蓄積部中。藉此,於濁度較大之水突發性地流入流水路內之情形時,可防止於切換部切換為非過濾狀態之前濁度較大之水通過濾材。It takes time to detect the turbidity by the turbidity detecting unit and switch to the non-filtering state by the switching unit. Therefore, by arranging the accumulation portion between the position where the turbidity detection unit detects the turbidity in the flow path and the filter medium, and the turbidity detection unit detects that the turbidity water passes through the filter material, It is temporarily stored in the accumulation unit. Thereby, when the water having a large turbidity suddenly flows into the flow path, it is possible to prevent the water having a large turbidity from passing through the filter material before the switching unit switches to the non-filtering state.
本發明之淨水器較佳為包含偵測通過濾材之水量之水量偵測部、與清洗濾材之清洗部。清洗部較佳為構成為,將由濁度偵測部所偵測之濁度以時間積分之值與將由水量偵測部所偵測之水量以時間積分之值的乘積大於特定值之情形時清洗濾材。Preferably, the water purifier of the present invention includes a water amount detecting portion for detecting the amount of water passing through the filter medium, and a cleaning portion for cleaning the filter medium. Preferably, the cleaning unit is configured to clean the turbidity detected by the turbidity detecting unit when the product of the time integral value and the water amount detected by the water amount detecting unit is greater than a specific value by a time integral value. Filter material.
即便不存在濁度較大之水突發性地通過濾材,亦會隨著濾材之使用時間、即通過濾材之合計水量增加,而導致濾材容易發生堵塞。又,通過濾材之水之濁度越大,濾材越容易發生堵塞。因此,於將由濁度偵測部所偵測之濁度以時間進行積分所得之值與將由水量偵測部所偵測之水量以時間進行積分所得之值的乘積大於特定值之情形時清洗部清洗濾材,藉此可更有效地防止濾材之淨水性能之下降。Even if the water having a large turbidity does not suddenly pass through the filter medium, the filter material is likely to be clogged as the time of use of the filter medium, that is, the total amount of water passing through the filter medium increases. Further, the larger the turbidity of the water passing through the filter medium, the more likely the filter material is clogged. Therefore, when the product obtained by integrating the turbidity detected by the turbidity detecting unit with time and the value obtained by integrating the amount of water detected by the water amount detecting unit with time is larger than a specific value, the cleaning unit The filter material is cleaned, thereby more effectively preventing a decrease in the water purification performance of the filter material.
如上所述,根據本發明,可提供一種能夠防止由突發性之原水之渾濁所導致之濾材之淨水性能之下降的淨水器。As described above, according to the present invention, it is possible to provide a water purifier capable of preventing a decrease in the water purification performance of the filter medium caused by the turbidity of the sudden raw water.
以下,基於圖式對本發明之實施形態進行說明。Hereinafter, embodiments of the present invention will be described based on the drawings.
(第1實施形態)(First embodiment)
如圖1所示,第1實施形態之淨水器1包含作為配置於流水路100中之濁度偵測部之濁度感測器110、銀離子溶解劑120、預濾器131、活性炭過濾器132、作為濾材之濁質除去過濾器133、儲存桶140、泵150、及空氣導入部160。又,淨水器1係於流水路100之外部包含控制部170、水位感測器143、及通知部144。流水路100中亦配置有第1淨水路導入閥101、排水閥102、第2淨水路導入閥103、灰水閥104、淨水閥105、逆洗閥106。流水路100之上游側之端部與供給自來水等原水之外部之配管連接。再者,原水除自來水以外,亦可為井水或河水。As shown in Fig. 1, the water purifier 1 of the first embodiment includes a turbidity sensor 110, a silver ion dissolving agent 120, a prefilter 131, and an activated carbon filter as turbidity detecting portions disposed in the flowing water path 100. 132. A turbidity removing filter 133 as a filter medium, a storage tub 140, a pump 150, and an air introduction unit 160. Further, the water purifier 1 includes a control unit 170, a water level sensor 143, and a notification unit 144 outside the water channel 100. The first water purification channel introduction valve 101, the drain valve 102, the second water purification channel introduction valve 103, the gray water valve 104, the water purification valve 105, and the backwash valve 106 are also disposed in the water channel 100. The upstream side of the flow path 100 is connected to a pipe to which the raw water such as tap water is supplied. In addition, the raw water may be well water or river water in addition to tap water.
濁度感測器110例如使用包含發光部與受光部,且構成為藉由偵測光之散射或光之透射而偵測水之濁度者。The turbidity sensor 110 uses, for example, a light-emitting portion and a light-receiving portion, and is configured to detect turbidity of water by detecting scattering of light or transmission of light.
於濁度感測器110之下游側,流水路100與2個配管連接。一配管中配置有第1淨水路導入閥101,另一配管中配置有排水閥102。第1淨水路導入閥101與排水閥102為切換部之一例。第1淨水路導入閥101與排水閥102係如後所述般藉由自控制部170接收控制信號而進行開閉。本實施形態中,將第1淨水路導入閥101與排水閥102設為電磁閥。On the downstream side of the turbidity sensor 110, the flow path 100 is connected to two pipes. The first purified water channel introduction valve 101 is disposed in one of the pipes, and the drain valve 102 is disposed in the other pipe. The first purified water channel introduction valve 101 and the drain valve 102 are examples of the switching portion. The first water purification channel introduction valve 101 and the drain valve 102 are opened and closed by receiving a control signal from the control unit 170 as will be described later. In the present embodiment, the first water purification channel introduction valve 101 and the drain valve 102 are used as solenoid valves.
配置有第1淨水路導入閥101之配管中配置有銀離子溶解劑120。作為銀離子溶解劑120,例如使用於聚乙烯顆粒物中捏合有銀離子溶解沸石者。若水接觸於此種銀離子溶解劑120,則銀離子自銀離子溶解劑120溶解至水中。The silver ion dissolving agent 120 is disposed in the pipe in which the first purified water channel introduction valve 101 is disposed. As the silver ion dissolving agent 120, for example, those in which silver ions are dissolved in the polyethylene particles are kneaded. If water is contacted with such a silver ion solubilizer 120, silver ions are dissolved from the silver ion solubilizer 120 into the water.
因流水路100內之構件經常接觸水,故流水路100或流水路100內之構件、尤其是各種過濾器內容易繁殖細菌。若細菌繁殖,則發生過濾器之堵塞而過濾器之淨水性能下降。因此,藉由將銀離子溶解劑120配置於流水路100中,可利用銀離子之殺菌效果抑制細菌之繁殖,而可防止過濾器之堵塞。Since the members in the flow path 100 are often in contact with water, bacteria are easily propagated in the members of the flow path 100 or the flow path 100, particularly in various filters. If the bacteria multiply, the filter is clogged and the filter's water purification performance is degraded. Therefore, by disposing the silver ion dissolving agent 120 in the flowing water path 100, it is possible to suppress the growth of bacteria by the sterilizing effect of silver ions, and it is possible to prevent clogging of the filter.
於銀離子溶解劑120之下游側連接有預濾器131。預濾器131係由網眼相對較大之不織布所構成。藉由預濾器131將通過預濾器131之水過濾,而除去水中之相對較大之雜質。A prefilter 131 is connected to the downstream side of the silver ion solubilizer 120. The prefilter 131 is composed of a non-woven fabric having a relatively large mesh. The water passing through the prefilter 131 is filtered by the prefilter 131 to remove relatively large impurities in the water.
於預濾器131之下游側連接有活性炭過濾器132。活性炭過濾器132係由活性炭所構成,其吸附水中之有機物而將其自水中除去。An activated carbon filter 132 is connected to the downstream side of the prefilter 131. The activated carbon filter 132 is composed of activated carbon, which adsorbs organic matter in water and removes it from water.
濁質除去過濾器133配置於活性炭過濾器132之下游側。濁質除去過濾器133為濾材之一例。濁質除去過濾器133係由網眼比較小之不織布所構成。濁質除去過濾器133亦可由膜所構成。藉由水通過濁質除去過濾器133,亦過濾除去較小之雜質。通過濁質除去過濾器133之水成為淨水。The turbidity removal filter 133 is disposed on the downstream side of the activated carbon filter 132. The turbidity removal filter 133 is an example of a filter medium. The turbidity removal filter 133 is composed of a nonwoven fabric having a relatively small mesh. The turbidity removal filter 133 may also be composed of a film. The filter 133 is removed by passing the water through the turbidity, and the smaller impurities are also removed by filtration. The water of the filter 133 is removed by the turbidity to become purified water.
於濁質除去過濾器133之下游側,流水路100連接於2個配管。於一配管中配置有第2淨水路導入閥103,於另一配管中配置有灰水閥104。第2淨水路導入閥103係如後所述般藉由自控制部170接收控制信號而進行開閉。由使用者對灰水閥104進行開閉。本實施形態中,將第2淨水路導入閥103設為電磁閥。On the downstream side of the turbidity removal filter 133, the flow path 100 is connected to two pipes. The second water purification channel introduction valve 103 is disposed in one of the pipes, and the gray water valve 104 is disposed in the other pipe. The second water purification channel introduction valve 103 is opened and closed by receiving a control signal from the control unit 170 as will be described later. The gray water valve 104 is opened and closed by the user. In the present embodiment, the second water purification passage introduction valve 103 is an electromagnetic valve.
於配置有第2淨水路導入閥103之配管上連接有儲存桶140。於儲存桶140內暫時蓄積流水路100中流通並流入至儲存桶140內之水。儲存桶140內收容有UV(ultraviolet,紫外線)照射器141與細菌感測器142。UV照射器141對蓄積於儲存桶140內之水照射紫外線。細菌感測器142偵測儲存桶140內之水中之細菌之數量並向控制部170發送信號。A storage tub 140 is connected to a pipe in which the second purified water channel introduction valve 103 is disposed. The water flowing through the storage tank 140 and flowing into the storage tub 140 is temporarily accumulated in the storage tub 140. A UV (ultraviolet) illuminator 141 and a bacteria sensor 142 are housed in the storage tub 140. The UV illuminator 141 illuminates the water stored in the storage tub 140 with ultraviolet rays. The bacteria sensor 142 detects the amount of bacteria in the water in the storage tub 140 and sends a signal to the control unit 170.
水位感測器143偵測儲存桶140內之水位並向控制部170發送信號。The water level sensor 143 detects the water level in the storage tub 140 and transmits a signal to the control unit 170.
於藉由細菌感測器142而於儲存桶140內之水中偵測出特定數量以上之細菌之情形時,通知部144鳴叫告警聲音,向使用者通知儲存桶140內之細菌為特定數量以上。When a certain number or more of bacteria are detected in the water in the storage tub 140 by the bacteria sensor 142, the notification unit 144 sounds an alarm sound to notify the user that the bacteria in the storage tub 140 are a certain number or more.
泵150送出蓄積於儲存桶140內之水。泵150構成為於打開後述之逆洗閥106時進行驅動。The pump 150 sends out the water accumulated in the storage tub 140. The pump 150 is configured to be driven when the backwash valve 106 described later is opened.
於泵150之下游側,流水路100連接於2個配管。於一配管中配置有淨水閥105,於另一配管中配置有逆洗閥106。由使用者對淨水閥105進行開閉。逆洗閥106係如後所述般藉由自控制部170接收控制信號而進行開閉。本實施形態中,將逆洗閥106設為電磁閥。On the downstream side of the pump 150, the flow path 100 is connected to two pipes. A water purification valve 105 is disposed in one of the pipes, and a backwash valve 106 is disposed in the other pipe. The water purification valve 105 is opened and closed by the user. The backwash valve 106 is opened and closed by receiving a control signal from the control unit 170 as will be described later. In the present embodiment, the backwash valve 106 is an electromagnetic valve.
配置有淨水閥105之配管連通於淨水器1之外部。另一方面,於配置有逆洗閥106之配管上連接有空氣導入部160。於連接有空氣導入部160之配管中,與逆洗閥106為相反側之端部連接於濁質除去過濾器133。The piping in which the water purification valve 105 is disposed is connected to the outside of the water purifier 1. On the other hand, the air introduction portion 160 is connected to the pipe in which the backwash valve 106 is disposed. The pipe connected to the air introduction portion 160 is connected to the turbidity removing filter 133 at the end opposite to the backwash valve 106.
空氣導入部160對自泵150送出至濁質除去過濾器133之水供給空氣。藉由對由泵150所送出之水供給空氣,而即便水量相同亦可提高水流之速度。The air introduction unit 160 supplies air to the water sent from the pump 150 to the turbidity removal filter 133. By supplying air to the water sent from the pump 150, the speed of the water flow can be increased even if the amount of water is the same.
將經空氣導入部160供給空氣之水供給至濁質除去過濾器133。供給至濁質除去過濾器133之水不會返回至儲存桶140內而自淨水器1排出。The water supplied to the air via the air introduction unit 160 is supplied to the turbidity removal filter 133. The water supplied to the turbidity removal filter 133 is not returned to the inside of the storage tub 140 but is discharged from the water purifier 1.
如圖2所示,淨水器1包含濁度感測器110、細菌感測器142、水位感測器143、第1淨水路導入閥101、排水閥102、第2淨水路導入閥103、逆洗閥106、及通知部144作為控制關聯之構成。濁度感測器110、細菌感測器142及水位感測器143向控制部170發送信號。控制部170根據自濁度感測器110、細菌感測器142及水位感測器143接收之信號,向第1淨水路導入閥101、排水閥102、第2淨水路導入閥103、逆洗閥106、及通知部144發送控制信號。As shown in FIG. 2, the water purifier 1 includes a turbidity sensor 110, a bacteria sensor 142, a water level sensor 143, a first water purification channel introduction valve 101, a drain valve 102, and a second water purification channel introduction valve. 103. The backwash valve 106 and the notification unit 144 are configured to be associated with each other. The turbidity sensor 110, the bacteria sensor 142, and the water level sensor 143 transmit signals to the control unit 170. The control unit 170 introduces the valve 101, the drain valve 102, the second clean water channel introduction valve 103, and the first water purification channel based on the signals received from the turbidity sensor 110, the bacteria sensor 142, and the water level sensor 143. The backwash valve 106 and the notification unit 144 transmit control signals.
於由濁度感測器110所偵測之原水之濁度為大於特定值例如2 NTU(比濁計濁度單位)之值時,控制部170向第1淨水路導入閥101與排水閥102發送控制信號,以使得關閉第1淨水路導入閥101,打開排水閥102。將關閉第1淨水路導入閥101並打開排水閥102之狀態作為非過濾狀態。When the turbidity of the raw water detected by the turbidity sensor 110 is greater than a specific value, for example, a value of 2 NTU (turbidity turbidity unit), the control unit 170 introduces the valve 101 and the drain valve to the first purified water passage. The control signal is transmitted 102 such that the first clean water inlet valve 101 is closed and the drain valve 102 is opened. The state in which the first purified water channel introduction valve 101 is closed and the drain valve 102 is opened is regarded as a non-filtering state.
於由濁度感測器110所偵測之原水之濁度為特定值例如2 NTU以下時,控制部170向第1淨水路導入閥101與排水閥102發送控制信號,以使得打開第1淨水路導入閥101,關閉排水閥102。將打開第1淨水路導入閥101並關閉排水閥102之狀態作為過濾狀態。When the turbidity of the raw water detected by the turbidity sensor 110 is a specific value, for example, 2 NTU or less, the control unit 170 transmits a control signal to the first purified water channel introduction valve 101 and the drain valve 102 so that the first signal is turned on. The water purification channel is introduced into the valve 101, and the drain valve 102 is closed. The state in which the first water purification channel introduction valve 101 is opened and the drain valve 102 is closed is used as a filtration state.
於非過濾狀態與過濾狀態之間進行切換時之濁度之值係根據使用淨水器1之環境或濾材之種類等加以調整。例如,於通常原水之濁度為0.01 NTU,而於原水之濁度大於1.0 NTU時不通過濁質除去過濾器133之情形時,由濁度感測器110所偵測之原水之濁度為1.0 NTU以下時切換為過濾狀態,由濁度感測器110所偵測之濁度大於1.0 NTU時切換為非過濾狀態。The value of the turbidity when switching between the non-filtering state and the filtering state is adjusted depending on the environment in which the water purifier 1 is used or the type of the filter medium. For example, when the turbidity of the normal raw water is 0.01 NTU, and when the turbidity of the raw water is greater than 1.0 NTU, the turbidity of the raw water detected by the turbidity sensor 110 is When it is less than 1.0 NTU, it is switched to the filtering state, and when the turbidity detected by the turbidity sensor 110 is greater than 1.0 NTU, it is switched to the non-filtering state.
又,於非過濾狀態與過濾狀態之間進行切換時之濁度之值亦可於淨水器1之動作時,根據特定期間內由濁度感測器110所偵測之濁度之值而決定。於以上述方式決定特定值之情形時,控制部170記憶特定期間內由濁度感測器110所偵測之濁度之值,求出所記憶之濁度之值之平均值與標準偏差。其次,控制部170使用所求出之濁度之平均值與標準偏差,求出(平均值+標準偏差×2),將該值作為特定值。控制部170係於由濁度感測器110所偵測之濁度之值為大於所求出之(平均值+標準偏差×2)之值時切換為非過濾狀態,原水不通過濁質除去過濾器133。又,控制部170係於由濁度感測器110所偵測之濁度之值為所求出之(平均值+標準偏差×2)以下之值時切換為過濾狀態,原水通過濁質除去過濾器133。Moreover, the value of the turbidity when switching between the non-filtering state and the filtering state may also be based on the value of the turbidity detected by the turbidity sensor 110 during the specific period of time during the operation of the water purifier 1. Decide. When the specific value is determined in the above manner, the control unit 170 stores the value of the turbidity detected by the turbidity sensor 110 during the specific period, and obtains the average value and the standard deviation of the value of the stored turbidity. Next, the control unit 170 obtains (average value + standard deviation × 2) using the obtained average value of the turbidity and the standard deviation, and uses the value as a specific value. The control unit 170 switches to the non-filtering state when the value of the turbidity detected by the turbidity sensor 110 is greater than the value (average + standard deviation × 2) obtained, and the raw water is not removed by the turbidity. Filter 133. Further, the control unit 170 switches to the filtered state when the value of the turbidity detected by the turbidity sensor 110 is less than or equal to the value (average value + standard deviation × 2), and the raw water is removed by the turbidity. Filter 133.
於由細菌感測器142所偵測之儲存桶140內之細菌之量為特定值以上之情形時,控制部170向通知部144發送控制信號,向使用者通知儲存桶140內之細菌數為特定數量以上。When the amount of bacteria in the storage tub 140 detected by the bacteria sensor 142 is greater than or equal to a specific value, the control unit 170 transmits a control signal to the notification unit 144 to notify the user that the number of bacteria in the storage tub 140 is More than a certain number.
又,於由水位感測器143所偵測之儲存桶140內之水低於特定水位之情形時,控制部170向第1淨水路導入閥101與第2淨水路導入閥103發送控制信號,以使得打開第1淨水路導入閥101與第2淨水路導入閥103。另一方面,於由水位感測器143所偵測之儲存桶140內之水為特定水位以上之情形時,向第1淨水路導入閥101發送控制信號,以關閉第1淨水路導入閥101。When the water in the storage tub 140 detected by the water level sensor 143 is lower than the specific water level, the control unit 170 transmits control to the first water purification channel introduction valve 101 and the second water purification channel introduction valve 103. The signal is such that the first purified water channel introduction valve 101 and the second water purification channel introduction valve 103 are opened. On the other hand, when the water in the storage tub 140 detected by the water level sensor 143 is equal to or higher than the specific water level, a control signal is sent to the first water purification channel introduction valve 101 to close the first water purification channel. Valve 101.
又,控制部170例如以固定之時間間隔向逆洗閥106發送控制信號,而將逆洗閥106進行開閉。逆洗閥106之開閉亦可與控制部170自細菌感測器142或水位感測器143接收之信號連動。若打開逆洗閥106,則對泵150(圖1)進行驅動。Moreover, the control unit 170 transmits a control signal to the backwash valve 106 at a fixed time interval, for example, and opens and closes the backwash valve 106. The opening and closing of the backwash valve 106 may also be linked to a signal received by the control unit 170 from the bacteria sensor 142 or the water level sensor 143. If the backwash valve 106 is opened, the pump 150 (Fig. 1) is driven.
對以上述方式構成之淨水器1之動作加以說明。The operation of the water purifier 1 configured as described above will be described.
於自來水等原水流入至流水路100內,並通過濁度感測器110時,藉由濁度感測器110而偵測原水之濁度。所偵測之濁度大於特定值例如2 NTU之情形時,自濁度感測器110向控制部170發送信號,而由控制部170控制使第1淨水路導入閥101關閉、使排水閥102打開。濁度大於特定濁度之水便不會流入至較第1淨水路導入閥101更下游側之流水路100,而通過排水閥102排出至淨水器1之外部。When the raw water such as tap water flows into the flowing water path 100 and passes through the turbidity sensor 110, the turbidity of the raw water is detected by the turbidity sensor 110. When the detected turbidity is greater than a specific value, for example, 2 NTU, the turbidity sensor 110 sends a signal to the control unit 170, and the control unit 170 controls the first clean water inlet valve 101 to be closed to make the drain valve. 102 opens. The water having a turbidity greater than the specific turbidity does not flow into the flow path 100 on the downstream side of the first purified water channel introduction valve 101, and is discharged to the outside of the water purifier 1 through the drain valve 102.
如上所述,偵測出濁度大於特定濁度之水不會通過濁質除去過濾器133等,而自淨水器1排出。As described above, it is detected that water having a turbidity greater than a specific turbidity is not discharged from the water purifier 1 by the turbidity removing filter 133 or the like.
另一方面,於由濁度感測器110所偵測之原水之濁度為特定值例如2 NTU以下之情形時,自濁度感測器110向控制部170發送信號,而由控制部170控制使第1淨水路導入閥101打開、使排水閥102關閉。特定濁度以下之水便會通過第1淨水路導入閥101,於流水路100內進入至較第1淨水路導入閥101更下游側。On the other hand, when the turbidity of the raw water detected by the turbidity sensor 110 is a specific value, for example, 2 NTU or less, the turbidity sensor 110 transmits a signal to the control unit 170, and the control unit 170 Control is performed to open the first water purification passage introduction valve 101 and close the drain valve 102. The water having a specific turbidity or lower is passed through the first purified water passage introduction valve 101, and enters the downstream side of the first purified water passage introduction valve 101 in the flow passage 100.
於第1淨水路導入閥101之下游側,水通過銀離子溶解劑120。此時,銀離子會溶解至水中。於未使用淨水器1而未向淨水器1內供給原水時,於淨水器1內部存在殘留之水之情形時,銀離子會逐漸溶解至水中,藉此可抑制水中之細菌繁殖。On the downstream side of the first purified water channel introduction valve 101, water passes through the silver ion dissolving agent 120. At this point, silver ions will dissolve into the water. When the raw water is not supplied to the water purifier 1 without using the water purifier 1, when there is residual water inside the water purifier 1, the silver ions are gradually dissolved in the water, thereby suppressing the growth of bacteria in the water.
其次,水通過預濾器131。藉由通過預濾器131而將相對較大之雜質自水中除去。Next, water passes through the prefilter 131. Relatively large impurities are removed from the water by passing through the prefilter 131.
其次,水通過活性炭過濾器132。藉由通過活性炭過濾器132,使水中之有機物吸附於活性炭而自水中除去。Second, water passes through the activated carbon filter 132. The organic matter in the water is removed from the water by adsorption to the activated carbon by the activated carbon filter 132.
其次,水通過濁質除去過濾器133。藉由通過濁質除去過濾器133,而將水中之較小之雜質除去。Next, the water is removed by the turbidity filter 133. The smaller impurities in the water are removed by removing the filter 133 by turbidity.
以上述方式生成淨水。Purified water is produced in the above manner.
將所生成之淨水蓄積於儲存桶140內。於由水位感測器143所偵測之儲存桶140內之水位低於特定水位之情形時,打開第2淨水路導入閥103,使通過濁質除去過濾器133之水流入至儲存桶140內。藉由UV照射器141對蓄積於儲存桶140內之水照射紫外線而進行殺菌。於由細菌感測器142所偵測之細菌之數量為特定數量以上之情形時,通知部144向使用者通知儲存桶140內之細菌為特定數量以上。The generated purified water is accumulated in the storage tub 140. When the water level in the storage tub 140 detected by the water level sensor 143 is lower than the specific water level, the second water purification channel introduction valve 103 is opened to allow the water passing through the turbidity removal filter 133 to flow into the storage tub 140. Inside. The water stored in the storage tub 140 is irradiated with ultraviolet rays by the UV irradiator 141 to be sterilized. When the number of bacteria detected by the bacteria sensor 142 is a specific number or more, the notification unit 144 notifies the user that the bacteria in the storage tub 140 are a certain number or more.
於通知部144未進行通知之情形時,使用者打開淨水閥105,則淨水通過淨水閥105而自淨水器1排出。使用者可利用淨水。When the notification unit 144 does not notify the user, when the user opens the water purification valve 105, the purified water is discharged from the water purifier 1 through the water purification valve 105. Users can use clean water.
另一方面,於通知部144進行通知之情形時,使用者可使利用UV照射器141之殺菌進一步長時間繼續。又,即便通知部144進行通知,使用者亦可打開淨水閥105。於此情形時,較佳為將自淨水器1排出之水用於洗滌等來代替飲用。On the other hand, when the notification unit 144 performs the notification, the user can continue the sterilization by the UV irradiator 141 for a long time. Further, even if the notification unit 144 notifies the user, the user can open the water purification valve 105. In this case, it is preferable to use the water discharged from the water purifier 1 for washing or the like instead of drinking.
又,淨水器1中,以特定時間間隔打開逆洗閥106,對泵150進行驅動,而進行濁質除去過濾器133之清洗。於儲存桶140內照射紫外線進行殺菌,將經淨化之水自與通常之水之流向為相反之方向供給至濁質除去過濾器133,藉此可清洗濁質除去過濾器133。將清洗濁質除去過濾器133之水直接自淨水器1排出。Further, in the water purifier 1, the backwash valve 106 is opened at a specific time interval, and the pump 150 is driven to perform cleaning of the turbidity removing filter 133. The sterilizing water is irradiated to the turbidity removing filter 133 by irradiating ultraviolet rays in the storage tub 140, and the purified water is supplied to the turbidity removing filter 133 in a direction opposite to the flow of the normal water. The water for cleaning the turbidity removing filter 133 is directly discharged from the water purifier 1.
又,使用者可打開灰水閥104,不將通過第2淨水路導入閥103之水蓄積於儲存桶140內,而直接自淨水器1排出。如上所述,將未蓄積於儲存桶140內而通過濁質除去過濾器133之後,未蓄積於儲存桶140內而直接排出至淨水器1之外之水作為灰水。灰水係藉由濁質除去過濾器133加以淨化,但不利用紫外線照射進行殺菌。因此,灰水理想的是用於洗滌等而非飲用。Further, the user can open the gray water valve 104, and the water that has passed through the second water purification channel introduction valve 103 is not stored in the storage tub 140, but is directly discharged from the water purifier 1. As described above, after the filter 133 is removed by the turbidity, it is not accumulated in the storage tub 140, and is not stored in the storage tub 140 and is directly discharged to the water outside the water purifier 1 as gray water. The gray water is purified by the turbidity removing filter 133, but is not sterilized by ultraviolet irradiation. Therefore, gray water is ideal for washing or the like rather than drinking.
再者,本實施形態中,對將第1淨水路導入閥101與排水閥102設為電磁閥進行了說明,但第1淨水路導入閥101與排水閥102亦可為其他閥。例如,第1淨水路導入閥101與排水閥102亦可構成為根據濁度感測器110所偵測之光之透射量、即流水路100內之亮度進行開閉。In the present embodiment, the first water purification channel introduction valve 101 and the drain valve 102 are described as solenoid valves. However, the first water purification channel introduction valve 101 and the drain valve 102 may be other valves. For example, the first water purification channel introduction valve 101 and the drain valve 102 may be configured to open and close according to the amount of light transmitted by the turbidity sensor 110, that is, the brightness in the water channel 100.
例如,作為排水閥102,可使用藉由光之照射而打開之光驅動閥。光驅動閥例如包含由光響應性物質所形成之可動膜。由光響應性物質所形成之可動膜係根據所照射之光之量而可逆地進行變形。藉由對包含此種可動膜之光驅動閥照射光,而可動膜可逆地進行變形,對光驅動閥進行驅動。用於排水閥102之光驅動閥例如構成為於接受多於特定量之散射光時打開,於接受特定量以下之散射光時關閉。For example, as the drain valve 102, a light-driven valve that is opened by irradiation of light can be used. The light-driven valve includes, for example, a movable film formed of a photoresponsive substance. The movable film formed of the photoresponsive substance is reversibly deformed in accordance with the amount of light to be irradiated. By irradiating light to the light-driven valve including such a movable film, the movable film is reversibly deformed to drive the light-driven valve. The light-driven valve for the drain valve 102 is configured, for example, to open when more than a certain amount of scattered light is received, and to close when receiving a predetermined amount or less of scattered light.
於流水路100內設置有對流水路100內之水照射光之發光部,若自發光部對流水路100內之水照射光,則根據濁度而散射光增加。因此,可藉由於流水路100內之接受散射光之位置設置由光驅動閥所構成之排水閥102,而於流水路100內之原水之濁度大於特定值時打開排水閥102,於為特定值以下時關閉排水閥102。The light-emitting portion that illuminates the water in the convection water passage 100 is provided in the flow channel 100. When the light from the light-emitting portion illuminates the water in the flow channel 100, the scattered light increases according to the turbidity. Therefore, the drain valve 102 composed of the light-driven valve can be disposed at a position where the scattered light is received in the flow path 100, and the drain valve 102 can be opened when the turbidity of the raw water in the flow path 100 is greater than a specific value. The drain valve 102 is closed when the value is below.
又,作為第1淨水路導入閥101,亦可同樣地使用光驅動閥。第1淨水路導入閥101配置於流水路100內之接受透射光之位置。流水路100內之透射光隨著流水路100內之原水之濁度上升而減少。因此,將構成為於接受特定量以上之透射光時打開,於接受少於特定量之透射光時關閉之光驅動閥用作第1淨水路導入閥101。藉此,可於流水路100內之原水之濁度為特定值以下之情形時打開第1淨水路導入閥101,於大於特定值之情形時關閉第1淨水路導入閥101。Further, as the first water purification channel introduction valve 101, a light-driven valve can be similarly used. The first purified water channel introduction valve 101 is disposed at a position in the water channel 100 that receives transmitted light. The transmitted light in the flowing water path 100 decreases as the turbidity of the raw water in the flowing water path 100 rises. Therefore, it is configured to open when a predetermined amount or more of transmitted light is received, and a light-driven valve that is closed when receiving less than a specific amount of transmitted light is used as the first purified water channel introduction valve 101. When the turbidity of the raw water in the water channel 100 is equal to or less than a specific value, the first water purification channel introduction valve 101 is opened, and when it is larger than a specific value, the first water purification channel introduction valve 101 is closed.
於第1淨水路導入閥101與排水閥102以上述方式構成之情形時,第1淨水路導入閥101與排水閥102不經由控制部170而進行開閉。例如,於流水路100內之亮度為濁度感測器110偵測出2 NTU以下之濁度時之流水路100內之亮度以上的亮度之情形時打開第1淨水路導入閥101並關閉排水閥102,以使得切換為過濾狀態。另一方面,於流水路100內之亮度低於濁度感測器110偵測出2 NTU以下之濁度時之流水路100內的亮度之情形時關閉第1淨水路導入閥101並打開排水閥102,以使得切換為非過濾狀態。When the first water purification channel introduction valve 101 and the drain valve 102 are configured as described above, the first water purification channel introduction valve 101 and the drain valve 102 are opened and closed without passing through the control unit 170. For example, when the brightness in the water channel 100 is greater than the brightness in the water channel 100 when the turbidity sensor 110 detects a turbidity of 2 NTU or less, the first water purification channel introduction valve 101 is opened and closed. The drain valve 102 is caused to switch to the filtered state. On the other hand, when the brightness in the flowing water path 100 is lower than the brightness in the flowing water path 100 when the turbidity sensor 110 detects the turbidity of 2 NTU or less, the first clean water introducing valve 101 is closed and opened. The drain valve 102 is such that it switches to a non-filtered state.
另一方面,如第1實施形態之淨水器1般,經由控制部170而控制第1淨水路導入閥101與排水閥102,於過濾狀態與非過濾狀態之間進行切換,藉此可使用簡單構成之閥作為第1淨水路導入閥101與排水閥102。On the other hand, as in the water purifier 1 of the first embodiment, the first water purification channel introduction valve 101 and the drain valve 102 are controlled via the control unit 170 to switch between the filtered state and the non-filtered state. A valve having a simple configuration is used as the first water purification passage introduction valve 101 and the drain valve 102.
如上所述,第1實施形態之淨水器1包含流水路100、濁質除去過濾器133、濁度感測器110、第1淨水路導入閥101及排水閥102。流水路100用以使水流適。濁質除去過濾器133係配置於流水路100中,使原水通過而成為淨水。濁度感測器110偵測流水路100中所流通之原水之濁度。第1淨水路導入閥101與排水閥102係於流水路100中所流通之水通過濁質除去過濾器133之過濾狀態、與通過流水路100之水不通過濁質除去過濾器133之非過濾狀態之間進行切換。As described above, the water purifier 1 of the first embodiment includes the water flow path 100, the turbidity removal filter 133, the turbidity sensor 110, the first purified water channel introduction valve 101, and the drain valve 102. The flow path 100 is used to make the water flow suitable. The turbidity removing filter 133 is disposed in the flowing water path 100, and passes the raw water to become purified water. The turbidity sensor 110 detects the turbidity of the raw water flowing through the flow path 100. The first water purification channel introduction valve 101 and the drain valve 102 are in a filtered state in which the water flowing through the water flow path 100 passes through the turbidity removal filter 133, and the water passing through the water flow path 100 does not pass through the turbidity removal filter 133. Switch between filtered states.
第1淨水路導入閥101與排水閥102構成為,於由濁度感測器110所偵測之原水之濁度為特定濁度以下之情形時切換為過濾狀態,於由濁度感測器110所偵測之原水之濁度大於特定濁度之情形時切換為非過濾狀態。The first water purification channel introduction valve 101 and the drain valve 102 are configured to switch to a filtered state when the turbidity of the raw water detected by the turbidity sensor 110 is below a specific turbidity, and is sensed by turbidity. When the turbidity of the raw water detected by the device 110 is greater than the specific turbidity, the device switches to the non-filtering state.
於由濁度感測器110所偵測之原水之濁度為特定濁度以下之情形時,第1淨水路導入閥101與排水閥102將淨水器1切換為過濾狀態,藉此流水路100中所流通之原水通過濁質除去過濾器133而成為淨水。When the turbidity of the raw water detected by the turbidity sensor 110 is equal to or lower than the specific turbidity, the first purified water inlet valve 101 and the drain valve 102 switch the water purifier 1 to the filtered state, thereby flowing water. The raw water flowing through the road 100 passes through the turbidity removing filter 133 to become purified water.
另一方面,於由濁度感測器110所偵測之原水之濁度大於特定濁度之情形時,第1淨水路導入閥101與排水閥102將淨水器1切換為非過濾狀態,藉此通過流水路100之水不通過濁質除去過濾器133。On the other hand, when the turbidity of the raw water detected by the turbidity sensor 110 is greater than the specific turbidity, the first purified water inlet valve 101 and the drain valve 102 switch the water purifier 1 to the non-filtering state. Thereby, the filter 133 is removed by the water passing through the flow path 100 without passing through the turbidity.
如上所述,藉由大於特定濁度之濁度之原水不通過濁質除去過濾器133,而即便濁度較大之原水突發性地流入至淨水器1內,亦可防止由於濁度較大之原水而導致濁質除去過濾器133堵塞。As described above, the raw water having a turbidity greater than a specific turbidity does not pass through the turbidity removing filter 133, and even if the raw water having a large turbidity suddenly flows into the water purifier 1, the turbidity can be prevented. The larger raw water causes the turbidity removal filter 133 to clog.
藉此,可提供一種可防止由突發性之原水之渾濁所導致之濁質除去過濾器133之淨水性能之下降的淨水器1。Thereby, it is possible to provide the water purifier 1 which can prevent the deterioration of the water purification performance of the turbidity removing filter 133 caused by the turbidity of the sudden raw water.
又,第1實施形態之淨水器1包含對第1淨水路導入閥101與排水閥102進行控制之控制部170。控制部170控制第1淨水路導入閥101與排水閥102,以使得於由濁度感測器110所偵測之原水之濁度為特定濁度以下之情形時切換為過濾狀態,於由濁度感測器110所偵測之原水之濁度大於特定濁度之情形時切換為非過濾狀態。Further, the water purifier 1 of the first embodiment includes a control unit 170 that controls the first purified water channel introduction valve 101 and the drain valve 102. The control unit 170 controls the first water purification channel introduction valve 101 and the drain valve 102 so as to switch to the filtration state when the turbidity of the raw water detected by the turbidity sensor 110 is below a specific turbidity. When the turbidity of the raw water detected by the turbidity sensor 110 is greater than the specific turbidity, the state is switched to the non-filtering state.
藉此,可使用簡單構成之第1淨水路導入閥101與排水閥102,於過濾狀態與非過濾狀態之間準確地進行切換。Thereby, the first clean water channel introduction valve 101 and the drain valve 102 which are simply configured can be used to accurately switch between the filtered state and the non-filtered state.
再者,亦可於泵150與淨水閥105之間設置作為加熱部之加熱器(未圖示)或作為冷卻部之冷卻裝置(未圖示)。例如,使用者可調節加熱器或冷卻裝置之驅動,來調節通過淨水閥105而排出之淨水之溫度。Further, a heater (not shown) as a heating unit or a cooling device (not shown) as a cooling unit may be provided between the pump 150 and the water purification valve 105. For example, the user can adjust the drive of the heater or the cooling device to adjust the temperature of the purified water discharged through the water purification valve 105.
如圖3所示,作為第1實施形態之其他例之淨水器2亦可連接於蓄積有原水之原水儲存桶220,而並非自水道直接將原水供給至流水路200內。如上所述,於將原水自原水儲存桶220供給至淨水器2內之情形時,於原水儲存桶220與濁度感測器110之間配置泵210。As shown in FIG. 3, the water purifier 2 as another example of the first embodiment may be connected to the raw water storage tank 220 in which raw water is accumulated, and the raw water is not directly supplied into the flowing water path 200 from the waterway. As described above, when the raw water is supplied from the raw water storage tank 220 to the water purifier 2, the pump 210 is disposed between the raw water storage tank 220 and the turbidity sensor 110.
藉此,即便無自來水般之水壓,亦可藉由泵210而自原水儲存桶220向淨水器2之流水路200內供給水,使水於流水路200內流通。Thereby, even if there is no water pressure like tap water, water can be supplied from the raw water storage tank 220 to the water passage 200 of the water purifier 2 by the pump 210, and the water can be circulated in the flow path 200.
(第2實施形態)(Second embodiment)
如圖4所示,作為第2實施形態之淨水器3與第1實施形態之淨水器1之不同點在於,第2實施形態之淨水器3包含作為蓄積部之緩衝部310。緩衝部310係配置於流水路300內濁度感測器110與第1淨水路導入閥101之間。淨水器3之其他構成與第1實施形態之淨水器1相同。As shown in FIG. 4, the water purifier 3 of the second embodiment differs from the water purifier 1 of the first embodiment in that the water purifier 3 of the second embodiment includes a buffer portion 310 as an accumulating portion. The buffer unit 310 is disposed between the turbidity sensor 110 and the first purified water channel introduction valve 101 in the flow channel 300. The other configuration of the water purifier 3 is the same as that of the water purifier 1 of the first embodiment.
緩衝部310只要構成為暫時蓄積水,則可為任一形狀,例如可為圓筒形狀之容器,亦可形成為捲成螺旋狀之管狀,又,亦可僅為長管。原水滯留於緩衝部310中之時間之長度可根據緩衝部310之形狀或直徑、長度加以調節。The buffer portion 310 may have any shape as long as it is configured to temporarily store water. For example, the buffer portion 310 may be a cylindrical container, or may be formed into a spiral tubular shape, or may be a long tube. The length of time during which the raw water stays in the buffer portion 310 can be adjusted according to the shape, diameter, and length of the buffer portion 310.
對以上述方式構成之第2實施形態之淨水器3之動作進行說明。此處,對與第1實施形態之淨水器1之動作之不同點進行說明。The operation of the water purifier 3 of the second embodiment configured as described above will be described. Here, differences from the operation of the water purifier 1 of the first embodiment will be described.
於自來水等原水流入至流水路300內,並通過濁度感測器110時,藉由濁度感測器110而偵測原水之濁度。於所偵測之濁度大於特定值例如2 NTU之情形時,自濁度感測器110向控制部170發送信號。控制部170向第1淨水路導入閥101與排水閥102發送控制信號,以使得關閉第1淨水路導入閥101,打開排水閥102。When the raw water such as tap water flows into the flow path 300 and passes through the turbidity sensor 110, the turbidity of the raw water is detected by the turbidity sensor 110. The self-turbidity sensor 110 transmits a signal to the control unit 170 when the detected turbidity is greater than a specific value, for example, 2 NTU. The control unit 170 transmits a control signal to the first water purification channel introduction valve 101 and the drain valve 102 so that the first water purification channel introduction valve 101 is closed and the drain valve 102 is opened.
另一方面,將藉由濁度感測器110而偵測濁度之原水暫時蓄積於緩衝部310中。原水暫時蓄積於緩衝部310中後,使其於流水路300內向下游側流通。On the other hand, the raw water which detects the turbidity by the turbidity sensor 110 is temporarily accumulated in the buffer part 310. After the raw water is temporarily accumulated in the buffer portion 310, it is caused to flow downstream in the flow channel 300.
有時至濁度感測器110向控制部170發送信號,控制部170向第1淨水路導入閥101與排水閥102發送控制信號,而關閉第1淨水路導入閥101並打開排水閥102為止之間需要花費時間。然而,由於原水暫時蓄積於較第1淨水路導入閥101更上游側之緩衝部310中,故而即便至關閉第1淨水路導入閥101為止需要花費時間,亦可防止濁度較大之原水通過第1淨水路導入閥101。The turbidity sensor 110 transmits a signal to the control unit 170, and the control unit 170 transmits a control signal to the first water purification channel introduction valve 101 and the drain valve 102, and closes the first water purification channel introduction valve 101 and opens the drain valve. It takes time between 102 and 102. However, since the raw water is temporarily stored in the buffer portion 310 on the upstream side of the first water purification channel introduction valve 101, it takes time to close the first water purification channel introduction valve 101, and it is possible to prevent the turbidity from being large. The raw water is introduced into the valve 101 through the first purified water passage.
如上所述,第2實施形態之淨水器3包含用以蓄積原水之緩衝部310。緩衝部310係配置於流水路300內藉由濁度感測器110而偵測濁度之位置與濁質除去過濾器133之間。As described above, the water purifier 3 of the second embodiment includes the buffer portion 310 for accumulating raw water. The buffer unit 310 is disposed between the position where the turbidity is detected by the turbidity sensor 110 in the flow channel 300 and the turbidity removal filter 133.
有時在藉由濁度感測器110偵測濁度、及藉由第1淨水路導入閥101與排水閥102切換為非過濾狀態之前之期間需要花費時間。對此,藉由於流水路300中利用濁度感測器110偵測濁度之位置與濁質除去過濾器133之間配置緩衝部310,則藉由濁度感測器110偵測出濁度之水在通過濁質除去過濾器133之前之期間,會被暫時蓄積於緩衝部310中。藉此,於濁度較大之水突發性地流入至流水路300內之情形時,可防止於第1淨水路導入閥101與排水閥102切換為非過濾狀態之前,濁度較大之水通過濁質除去過濾器133。It takes time to detect the turbidity by the turbidity sensor 110 and the period before the first clean water inlet valve 101 and the drain valve 102 are switched to the non-filtering state. In this regard, by arranging the buffer portion 310 between the position where the turbidity sensor 110 detects the turbidity in the flow path 300 and the turbidity removing filter 133, the turbidity is detected by the turbidity sensor 110. The water is temporarily accumulated in the buffer portion 310 during the period before the filter 133 is removed by the turbidity. Therefore, when the water having a large turbidity suddenly flows into the water channel 300, it is possible to prevent the turbidity from being large before the first water purification channel introduction valve 101 and the drain valve 102 are switched to the non-filtering state. The water is removed by the turbidity filter 133.
第2實施形態之淨水器3之其他構成與效果與第1實施形態之淨水器1相同。The other configuration and effects of the water purifier 3 of the second embodiment are the same as those of the water purifier 1 of the first embodiment.
(第3實施形態)(Third embodiment)
如圖5所示,作為第3實施形態之淨水器4與第1實施形態之淨水器1之不同點在於,第3實施形態之淨水器4包含作為水量偵測部之流量感測器410。流量感測器410係配置於流水路400中第1淨水路導入閥101與銀離子溶解劑120之間。流量感測器410偵測流水路400中通過第1淨水路導入閥101之原水之流量,並向控制部170發送信號。與第1實施形態之淨水器1同樣地,濁度感測器110偵測流水路400中所流通之原水之濁度,並向控制部170發送信號。As shown in FIG. 5, the water purifier 4 of the third embodiment is different from the water purifier 1 of the first embodiment in that the water purifier 4 of the third embodiment includes flow sensing as a water amount detecting unit. 410. The flow rate sensor 410 is disposed between the first water purification channel introduction valve 101 and the silver ion dissolving agent 120 in the flow channel 400. The flow rate sensor 410 detects the flow rate of the raw water passing through the first purified water channel introduction valve 101 in the flow channel 400, and transmits a signal to the control unit 170. Similarly to the water purifier 1 of the first embodiment, the turbidity sensor 110 detects the turbidity of the raw water flowing through the flow path 400 and transmits a signal to the control unit 170.
泵150、逆洗閥106及空氣導入部160構成清洗部。逆洗閥106係根據自控制部170接收之信號而進行開閉。The pump 150, the backwash valve 106, and the air introduction unit 160 constitute a washing unit. The backwash valve 106 is opened and closed based on a signal received from the control unit 170.
控制部170係根據自濁度感測器110接收之信號與自流量感測器410接收之信號,求出濁度與水量之乘積。控制部170係於所求出之濁度與水量之乘積大於特定值之情形時向逆洗閥106發送控制信號,以使泵150驅動而打開逆洗閥106。The control unit 170 determines the product of the turbidity and the amount of water based on the signal received from the turbidity sensor 110 and the signal received from the flow sensor 410. The control unit 170 transmits a control signal to the backwash valve 106 when the product of the obtained turbidity and the amount of water is larger than a specific value, so that the pump 150 is driven to open the backwash valve 106.
第3實施形態之淨水器4之其他構成與第1實施形態之淨水器1相同。The other configuration of the water purifier 4 of the third embodiment is the same as that of the water purifier 1 of the first embodiment.
對以上述方式構成之淨水器4之動作進行說明。此處,對與第1實施形態之淨水器1之動作之不同點進行說明。The operation of the water purifier 4 configured as described above will be described. Here, differences from the operation of the water purifier 1 of the first embodiment will be described.
若原水流入至淨水器4之流水路400內,則濁度感測器110偵測流水路400中所流通之原水之濁度,並向控制部170發送信號。When the raw water flows into the flow path 400 of the water purifier 4, the turbidity sensor 110 detects the turbidity of the raw water flowing through the flow path 400, and transmits a signal to the control unit 170.
於淨水器4切換為過濾狀態之情形時,通過第1淨水路導入閥101而流入至濁質除去過濾器133之原水會通過流量感測器410。流量感測器410偵測流水路400中通過第1淨水路導入閥101之原水之水量,並向控制部170發送信號。When the water purifier 4 is switched to the filtration state, the raw water that has flowed into the turbidity removal filter 133 through the first purified water channel introduction valve 101 passes through the flow rate sensor 410. The flow rate sensor 410 detects the amount of water in the raw water passing through the first water purification channel introduction valve 101 in the flow path 400, and transmits a signal to the control unit 170.
控制部170根據自濁度感測器110接收之信號,將由濁度感測器110所偵測之濁度以時間進行積分。又,控制部170根據自流量感測器410接收之信號,將由流量感測器410所偵測之流量以時間進行積分。第3實施形態中,控制部170係以於濁質除去過濾器133經逆洗後所經過之時間,將所偵測之濁度與流量分別積分。The control unit 170 integrates the turbidity detected by the turbidity sensor 110 by time based on the signal received from the turbidity sensor 110. Moreover, the control unit 170 integrates the flow rate detected by the flow sensor 410 with time based on the signal received from the flow sensor 410. In the third embodiment, the control unit 170 integrates the detected turbidity and the flow rate, respectively, for the elapsed time after the turbidity removal filter 133 is backwashed.
控制部170求出以時間將濁度進行積分之值與以時間將流量進行積分之值之乘積。控制部170係於所求出之乘積大於特定值之情形時向逆洗閥106發送控制信號,以使泵150驅動而打開逆洗閥106。The control unit 170 obtains the product of the value obtained by integrating the turbidity with time and the value of integrating the flow rate with time. The control unit 170 transmits a control signal to the backwash valve 106 when the calculated product is larger than a specific value to drive the pump 150 to open the backwash valve 106.
若驅動泵150,打開逆洗閥106,則儲存桶140內之水通過泵150、逆洗閥106及空氣導入部160,自與通常之水之流向為相反之方向流入至濁質除去過濾器133,進行濁質除去過濾器133之逆洗。將用以逆洗之淨水直接自淨水器4排出。When the pump 150 is driven and the backwash valve 106 is opened, the water in the storage tank 140 passes through the pump 150, the backwash valve 106, and the air introduction portion 160, and flows into the turbidity removing filter in a direction opposite to the flow of the normal water. 133, backwashing of the turbidity removal filter 133 is performed. The purified water used for backwashing is directly discharged from the water purifier 4.
如上所述,第3實施形態之淨水器4包含偵測通過濁質除去過濾器133之水量之流量感測器410、清洗濁質除去過濾器133之逆洗閥106、及空氣導入部160。逆洗閥106與空氣導入部160構成為,於將由濁度感測器110所偵測之濁度以時間積分之值與將由流量感測器410所偵測之水量以時間積分之值的乘積大於特定值之情形時,清洗濁質除去過濾器133。As described above, the water purifier 4 of the third embodiment includes the flow rate sensor 410 for detecting the amount of water passing through the turbidity removing filter 133, the backwash valve 106 for cleaning the turbidity removing filter 133, and the air introducing portion 160. . The backwash valve 106 and the air introduction portion 160 are configured to multiply the value of the turbidity detected by the turbidity sensor 110 by the time integral value and the amount of water to be detected by the flow sensor 410 as a time integral value. When it is larger than a specific value, the turbidity removing filter 133 is washed.
即便不存在濁度較大之水突發性地通過濁質除去過濾器133,亦會隨著濁質除去過濾器133之使用時間經過、即通過濁質除去過濾器133之合計水量增加,而濁質除去過濾器133容易發生堵塞。又,通過濁質除去過濾器133之水之濁度越大,濁質除去過濾器133越容易發生堵塞。因此,於將由濁度感測器110所偵測之濁度以時間積分之值與將由流量感測器410所偵測之水量以時間積分之值的乘積大於特定值之情形時,逆洗閥106與空氣導入部160清洗濁質除去過濾器133,藉此可更有效地防止濁質除去過濾器133之淨水性能之下降。Even if the water having a large turbidity is suddenly passed through the turbidity removing filter 133, the total amount of water passing through the turbidity removing filter 133 increases as the usage time of the turbidity removing filter 133 passes, that is, The turbidity removal filter 133 is prone to clogging. Further, the greater the turbidity of the water removed by the turbidity removing filter 133, the more likely the turbidity removing filter 133 is clogged. Therefore, when the product of the turbidity detected by the turbidity sensor 110 and the value of the time amount integrated by the flow sensor 410 is greater than a specific value, the backwash valve is used. The air-introducing portion 160 and the air introduction unit 160 wash the turbidity removal filter 133, whereby the deterioration of the water purification performance of the turbidity removal filter 133 can be more effectively prevented.
第3實施形態之淨水器4之其他構成與效果與第1實施形態之淨水器1相同。The other configuration and effects of the water purifier 4 of the third embodiment are the same as those of the water purifier 1 of the first embodiment.
應認為以上所揭示之實施形態於所有方面為例示,而非限制性者。本發明之範圍由申請專利範圍所表示,而非以上實施形態,且其包含與申請專利範圍均等之意義及範圍內之所有修正與變形。The embodiments disclosed above are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the scope of the claims, and not in the scope of the claims.
本發明可提供一種可防止由突發性之原水之渾濁所導致之濾材之淨水性能之下降的淨水器,因此於使用濾材而使原水成為淨水之淨水器方面有用。The present invention can provide a water purifier capable of preventing a decrease in the water purification performance of a filter material caused by turbidity of a sudden raw water. Therefore, it is useful for using a filter material to make raw water a water purifier for purified water.
