在控制部57會被輸入來自用以設定運轉行程等之輸入設定部58的資訊。控制部57會以輸入後的資訊為依據，使顯示部59顯示已設定的內容來通知使用者。又，藉由輸入設定部58而設定運轉開始後，來自偵測水槽33內的水位的水位偵測部46等的數據會被輸入控制部57，控制部57便會透過負荷驅動部(未圖示)來控制排水閥43、供水部44、送風扇48、及加熱器47等的動作。又，控制部57會透過驅動電路(未圖示)來控制馬達35。控制部57會進行由清洗、沖水、脫水、及乾燥之至少1個所構成的洗滌步驟的運轉。The control unit 57 receives information from the input setting unit 58 for setting the operation stroke and the like.

(shown) to control the operations of the drain valve 43, water supply part 44, blower fan 48, heater 47, etc. In addition, the control unit 57 controls the motor 35 through a drive circuit (not shown). The control unit 57 performs a washing step consisting of at least one of washing, flushing, dehydration, and drying.
泡沫偵測部70是由配設於水槽33之下方的下側的電極70a、及配設於水槽33之上方，或是在溫風送風路徑49內配設於從溫風送風口51算起之預定區域內的上側的電極70b之一對所構成。此處，所謂預定區域是意指在水槽33內所產生之洗劑泡沫可以到達上側的電極70b的區域。這是由於藉由洗劑泡沫到達上側的電極70b，便可偵測洗劑泡沫之產生的緣故。另外，上側的電極70b配設於比下側的電極70a更高的位置。The foam detection part 70 is composed of an electrode 70a disposed on the lower side below the water tank 33, and is disposed above the water tank 33, or is disposed in the warm air supply path 49 from the warm air supply port 51. It is composed of a pair of upper electrodes 70b in a predetermined area. Here, the predetermined area means an area where the lotion foam generated in the water tank 33 can reach the upper electrode 70b. This is because the generation of lotion foam can be detected when the lotion foam reaches the upper electrode 70b. In addition, the upper electrode 70b is arranged at a higher position than the lower electrode 70a.
接著，使用圖1，針對下側的電極70a與上側的電極70b配設的位置更進一步地進行說明。水位h1、h2、h3皆為顯示以水槽33之下端為基準時之水槽33內的洗滌水的水位。水位h1是執行後述之正常清洗程序時的水位。水位h2是相當於旋轉滾筒31之下端的高度位置的水位。水位h3是相當於下側的電極70a的高度位置的水位。如圖1所示地，水位的高度是成為h1＞h2＞h3的關係。作為一例，水位h1比水位h2高出100mm左右。Next, the positions where the lower electrode 70a and the upper electrode 70b are arranged will be further described using FIG. 1 . The water levels h1, h2, and h3 all indicate the water levels of the wash water in the water tank 33 when the lower end of the water tank 33 is used as a reference. The water level h1 is the water level when performing the normal cleaning procedure described below. The water level h2 is a water level corresponding to the height position of the lower end of the rotating drum 31 . The water level h3 is a water level corresponding to the height position of the lower electrode 70a. As shown in Figure 1, the height of the water level is in the relationship h1>h2>h3. As an example, the water level h1 is about 100 mm higher than the water level h2.
下側的電極70a配設於相當於比水位h2更低的水位h3的高度位置。亦即，下側的電極70a在水槽33之下方配設於比旋轉滾筒31更低的位置。藉此，便可以區別泡沫偵測部70的短路與異常發泡來進行辨識。上側的電極70b配設於比水位h1更高的位置。The lower electrode 70a is disposed at a height corresponding to the water level h3 which is lower than the water level h2. That is, the lower electrode 70 a is disposed below the water tank 33 at a lower position than the rotating drum 31 . Thereby, short circuit and abnormal foaming of the foam detection part 70 can be distinguished for identification. The upper electrode 70b is disposed higher than the water level h1.
另外，在圖1中，下側的電極70a及上側的電極70b雖然是配設於水槽33之後方，但並不限於此，下側的電極70a及上側的電極70b亦可配設於水槽33之前方。In addition, in FIG. 1 , although the lower electrode 70 a and the upper electrode 70 b are disposed behind the water tank 33 , the present invention is not limited thereto. The lower electrode 70 a and the upper electrode 70 b may also be disposed in the water tank 33 . Ahead.
泡沫偵測部70連接於電阻值判定電路(未圖示)。藉由與電阻值判定電路內之基準電阻的比較，會檢測出下側的電極70a與上側的電極70b間之電阻。只要下側的電極70a與上側的電極70b間之電阻值為閾值以上，控制部57便會判別為沒有泡沫進入一對電極間。若泡沫侵入一對電極間，在浸水之下側的電極70a與上側的電極70b之間便會形成由泡沫所造成之通電路徑，而會檢測到比閾值更低的電阻值。電阻值判定電路之判定用電阻值在有泡沫存在時是設為小於閾值(例如，500kΩ)，且在泡沫不存在時是設為閾值(例如，500kΩ)以上。The foam detection unit 70 is connected to a resistance value determination circuit (not shown). By comparing with the reference resistance in the resistance value determination circuit, the resistance between the lower electrode 70a and the upper electrode 70b is detected. As long as the resistance value between the lower electrode 70a and the upper electrode 70b is equal to or higher than the threshold value, the control unit 57 will determine that no foam has entered between the pair of electrodes. If foam invades between a pair of electrodes, an electrical path caused by the foam will be formed between the lower electrode 70a and the upper electrode 70b immersed in water, and a resistance value lower than the threshold value will be detected. The determination resistance value of the resistance value determination circuit is set to be less than the threshold value (for example, 500 kΩ) when bubbles are present, and is set to be above the threshold value (for example, 500 kΩ) when bubbles are not present.
針對如以上所構成之滾筒式洗衣機，使用圖2至圖4，來說明在洗滌中以泡沫偵測部偵測到泡沫時的動作、作用。Regarding the drum-type washing machine configured as above, the operation and function when the foam detection unit detects foam during washing will be described using FIGS. 2 to 4 .
圖2是本發明之實施形態1中之滾筒式洗衣機的控制部的動作流程圖，圖3(a)是在同滾筒式洗衣機的泡沫偵測部中產生異常發泡沫時的示意圖，圖3(b)是在同滾筒式洗衣機的泡沫偵測部中產生因堆積物所造成之短路時的示意圖，圖4是顯示同滾筒式洗衣機的泡沫偵測部之電阻值與水槽內之水位的時間變化的示意圖。Fig. 2 is an operation flow chart of the control unit of the drum-type washing machine in Embodiment 1 of the present invention. Fig. 3(a) is a schematic diagram when abnormal foaming occurs in the foam detection unit of the drum-type washing machine. Fig. 3(a) b) is a schematic diagram when a short circuit caused by accumulation occurs in the foam detection part of the same drum-type washing machine. Figure 4 shows the time change of the resistance value of the foam detection part of the same drum-type washing machine and the water level in the water tank. schematic diagram.
開始清洗步驟後，泡沫偵測部70便會開始電阻值的偵測。在水槽33內的水位到達相當於旋轉滾筒31之下端所在的高度之水位h2(S101)為止的期間中，藉由泡沫偵測部70所檢測到的電阻值未低於閾值(例如，500kΩ)時(S102、No)，控制部57便會判斷在一對電極間未發生短路而進行正常清洗程序(S103)。此處，所謂正常清洗程序(S103)是指例如供水至水位h1，然後將旋轉滾筒31以旋轉12秒後停止1秒之攪拌時間，並且以旋轉數45r/min來進行運轉。此處，所謂正常清洗程序亦稱為第1清洗程序。After starting the cleaning step, the foam detection unit 70 will start detecting the resistance value. During the period until the water level in the water tank 33 reaches the water level h2 corresponding to the height of the lower end of the rotating drum 31 (S101), the resistance value detected by the foam detection unit 70 does not fall below the threshold value (for example, 500 kΩ) (S102, No), the control unit 57 will determine that a short circuit does not occur between the pair of electrodes and perform the normal cleaning process (S103). Here, the so-called normal cleaning procedure (S103) refers to, for example, supplying water to the water level h1, and then rotating the rotating drum 31 for 12 seconds and then stopping for a stirring time of 1 second, and operating at a rotation speed of 45 r/min. Here, the so-called normal cleaning process is also called the first cleaning process.
如以圖4之虛線B所示地，在正常清洗程序(S103)中，在到達水位h2之後會判定泡沫偵測部70之電阻值是否小於閾值(S104)，若電阻值小於閾值，控制部57便會判定發生了異常發泡(S105)。異常發泡是因為包含洗劑成分之洗滌水藉由旋轉滾筒31的旋轉而被攪拌所發生，如圖3(a)所示地，會使一對電極間通電。當判定發生了異常發泡時，控制部57會進行例如藉由排水部43將水槽33內的水排水(S106)等消泡程序。As shown by the dotted line B in Figure 4, in the normal cleaning process (S103), after reaching the water level h2, it will be determined whether the resistance value of the foam detection part 70 is less than the threshold value (S104). If the resistance value is less than the threshold value, the control part 57, it will be determined that abnormal foaming has occurred (S105). Abnormal foaming occurs because the wash water containing detergent components is stirred by the rotation of the rotating drum 31, and as shown in FIG. 3(a), electricity is energized between the pair of electrodes. When it is determined that abnormal foaming has occurred, the control unit 57 performs a defoaming process such as draining the water in the water tank 33 through the drainage unit 43 (S106).
然後，在結束第1預定時間，例如15分鐘的正常清洗程序(S107)後，控制部57會結束清洗步驟(S108)並轉移至下一步驟。Then, after the first predetermined time, for example, 15 minutes of normal cleaning program (S107), the control unit 57 ends the cleaning step (S108) and moves to the next step.
另一方面，如以圖4之實線A所示地，若在水位到達h2之前泡沫偵測部70之電阻值就已經小於閾值(S102，Yes)，控制部57便可以判斷異常發泡並未發生。這是由於在水槽33內的水位到達h2為止的期間，包含洗劑成分之洗滌水並未藉由旋轉滾筒31的旋轉而被攪拌，從而沒有產生異常發泡的緣故。因此，在電阻值小於閾值時，可以判定產生了電極間之短路，因此若在水位到達h2之前電阻值就已經小於閾值(S102，Yes)，控制部57便會進行發生了短路的判定(S109)。On the other hand, as shown by the solid line A in Figure 4, if the resistance value of the foam detection part 70 is already less than the threshold value before the water level reaches h2 (S102, Yes), the control part 57 can determine abnormal foaming and Didn't happen. This is because the wash water containing the detergent components is not stirred by the rotation of the rotating drum 31 until the water level in the water tank 33 reaches h2, so that abnormal foaming does not occur. Therefore, when the resistance value is less than the threshold value, it can be determined that a short circuit has occurred between the electrodes. Therefore, if the resistance value is already less than the threshold value before the water level reaches h2 (S102, Yes), the control unit 57 will determine that a short circuit has occurred (S109 ).
電極間之短路是因為堆積於電極間之堆積物所引起。所謂堆積物是指洗劑成分之殘渣(洗劑殘留物)或出自於洗滌物之線頭等。當該等堆積於泡沫偵測部70的電極間時，如圖3(b)所示地，洗滌水會藉由表面張力而以洗劑成分之殘渣或線頭為介質來形成薄膜，使得電極間短路。The short circuit between the electrodes is caused by the accumulation of deposits between the electrodes. Deposits refer to residues of detergent ingredients (detergent residues) or lint from laundry. When these are accumulated between the electrodes of the foam detection part 70, as shown in FIG. 3(b), the washing water will use the residue or lint of the detergent component as a medium to form a thin film through surface tension, so that the electrodes short circuit between.
S109之後，不論泡沫偵測部70所檢測之電阻值成為何種數值，在清洗結束(S108)到轉移至下一步驟為止的期間，都不會進行藉由排水部43將水槽33內的水排水的動作。這是由於如前述地在一對電極間附著了泡沫以外之物，使得控制部57處於無法依據一對電極間之電阻值來正確地判斷在水槽33內是否有異常發泡的狀態的緣故。當判定為短路(S109)時，泡沫偵測部70並未正常發揮功能。因此，若依據泡沫偵測部70之判定進行排水動作，就會有實際上並未異常發泡卻錯誤偵測為異常發泡之虞。一旦發生錯誤偵測，不僅會引起無用的排水，水槽33內的洗滌水所含的洗劑成分也會一起被排水，因此洗淨性能會明顯降低。After S109, no matter what value the resistance value detected by the foam detection unit 70 becomes, the water in the water tank 33 will not be drained by the drain unit 43 from the end of cleaning (S108) to the next step. Drainage action. This is because as mentioned above, something other than foam has adhered between the pair of electrodes, and the control unit 57 is in a state in which it is unable to accurately determine whether there is abnormal foaming in the water tank 33 based on the resistance value between the pair of electrodes. When it is determined that there is a short circuit (S109), the foam detection unit 70 does not function normally. Therefore, if the drainage operation is performed based on the determination of the foam detection unit 70, there is a risk that abnormal foaming may be detected incorrectly even though abnormal foaming is not actually occurring. Once an erroneous detection occurs, not only will useless drainage be caused, but the detergent components contained in the washing water in the water tank 33 will also be drained together, so the cleaning performance will be significantly reduced.
但是，S109之後，到結束清洗步驟(S108)為止的期間，會有異常發泡產生的可能性，因此在進行了短路判定(S109)時，控制部57為了抑制異常發泡，會執行第1弱清洗程序(S110)。所謂第1弱清洗程序是指例如將旋轉滾筒31以旋轉10秒後停止5秒之弱攪拌時間，並且以旋轉數35r/min來進行運轉。第1弱清洗程序由於攪拌比正常清洗程序(S103)更弱，因此可以抑制起泡。另外，所謂「攪拌比正常清洗程序更弱」是意指旋轉滾筒31之旋轉數及旋轉時間的至少一者比正常清洗程序更小。此處，所謂第1弱清洗程序亦稱為第2清洗程序。However, after S109 and until the cleaning step is completed (S108), abnormal foaming may occur. Therefore, when the short circuit determination is made (S109), the control unit 57 executes the first step to suppress abnormal foaming. Weak cleaning program (S110). The first weak cleaning program means, for example, that the rotating drum 31 is rotated for 10 seconds and then stopped for a weak stirring time of 5 seconds, and is operated at a rotation speed of 35 r/min. The first weak cleaning program can suppress foaming because the stirring is weaker than the normal cleaning program (S103). In addition, the so-called "stirring is weaker than the normal cleaning process" means that at least one of the rotation number and the rotation time of the rotating drum 31 is smaller than the normal cleaning process. Here, the so-called first weak cleaning process is also called a second cleaning process.
之後，持續清洗步驟，且持續第2預定時間(S111)，例如15分鐘之清洗程序後，控制部57會結束清洗步驟(S108)並轉移至下一步驟。After that, the cleaning step continues for a second predetermined time (S111), for example, after 15 minutes of cleaning, the control unit 57 ends the cleaning step (S108) and moves to the next step.
然後，依序進行沖水、脫水、乾燥等一系列之洗滌運轉的運轉，並在運轉結束時，控制部57會使顯示部59顯示已進行了短路判定來通知使用者。藉此，使用者會認知到泡沫偵測部70並未正常發揮功能，而可以使洗淨水槽33或旋轉滾筒31本身的行程(例如槽洗淨行程)運轉。藉此，堆積於泡沫偵測部70之一對電極間的洗劑殘留物等會被除去，並且可以防止在一對電極間短路的狀態下繼續使用洗衣機。Then, a series of washing operations such as flushing, dehydration, and drying are performed in sequence, and at the end of the operation, the control unit 57 causes the display unit 59 to display that a short circuit determination has been made to notify the user. Thereby, the user will recognize that the foam detection unit 70 does not function properly, and can operate the washing tank 33 or the rotating drum 31 itself (for example, the tank cleaning stroke). Thereby, the detergent residue accumulated between the pair of electrodes of the foam detection part 70 will be removed, and the washing machine can be prevented from being used in a short-circuited state between the pair of electrodes.
如以上地，本揭示中之滾筒式洗衣機具備：洗衣機本體39；水槽33，彈性地支撐於洗衣機本體39內部；旋轉滾筒31，內包於水槽33，並配設成旋轉自如；供水閥44，對水槽33內供水；水位偵測部46，偵測水槽33內的水位；排水閥43，將水槽33內的水排水；泡沫偵測部70，由一對電極，亦即下側的電極70a及上側的電極70b所構成；及控制部57，控制由清洗、沖水、及脫水之至少1個所構成的洗滌運轉。在藉由供水部44而供水至水槽33內的水的水位到達預定水位為止的期間中，電極70a、70b間之電阻低於預定值時，控制部57會判定電極70a、70b間短路。As mentioned above, the drum-type washing machine in this disclosure includes: a washing machine body 39; a water tank 33 elastically supported inside the washing machine body 39; a rotating drum 31 enclosed in the water tank 33 and configured to rotate freely; a water supply valve 44. Supply water to the water tank 33; the water level detection part 46 detects the water level in the water tank 33; the drain valve 43 drains the water in the water tank 33; the foam detection part 70 consists of a pair of electrodes, that is, the lower electrode 70a and an upper electrode 70b; and a control unit 57 that controls a washing operation consisting of at least one of washing, flushing, and dehydration. When the resistance between the electrodes 70a and 70b is lower than the predetermined value while the water supply unit 44 supplies water until the water level in the water tank 33 reaches the predetermined level, the control unit 57 determines that the electrodes 70a and 70b are short-circuited.
藉此，即便在下側的電極70a與上側的電極70b之間產生短路的情況下，仍可抑制因異常發泡所造成之泡沫的增大，並且可以防止不必要的排水。因此，本實施形態中之滾筒式洗衣機可以適當地處理泡沫偵測部70的短路。Thereby, even if a short circuit occurs between the lower electrode 70a and the upper electrode 70b, the increase of foam due to abnormal foaming can be suppressed, and unnecessary drainage can be prevented. Therefore, the drum-type washing machine in this embodiment can properly deal with the short circuit of the foam detection part 70 .
預定水位亦可相當於旋轉滾筒31之下端所在的高度。The predetermined water level may also be equivalent to the height of the lower end of the rotating drum 31 .
下側的電極70a亦可配設於比預定水位更低的位置。The lower electrode 70a may be disposed lower than a predetermined water level.
下側的電極70a設置於水槽33之下方，上側的電極70b設置於水槽33之上方亦可。The lower electrode 70a may be provided below the water tank 33, and the upper electrode 70b may be provided above the water tank 33.
滾筒式洗衣機亦可更具備：溫風送風路徑49，將用以使洗滌物乾燥的溫風循環；及溫風送風口51，形成於水槽33之背面上方，並將溫風導入水槽33內。下側的電極70a設置於水槽33之下方，上側的電極70b在溫風送風路徑49內設置於從溫風送風口51算起之預定區域內亦可。The drum-type washing machine may further include: a warm air supply path 49 that circulates warm air for drying laundry; and a warm air supply port 51 that is formed above the back of the water tank 33 and introduces warm air into the water tank 33 . The lower electrode 70a may be provided below the water tank 33, and the upper electrode 70b may be provided in a predetermined area from the warm air blowing port 51 in the warm air blowing path 49.
亦可作成為：在藉由供水部44而供水至水槽33內的水位到達預定水位為止的期間中，電極70a、70b間之電阻不低於預定值，且，在到達預定水位後，電極間之電阻低於預定值時，控制部57會藉由排水閥43進行排水動作。It may also be configured that the resistance between the electrodes 70a and 70b does not fall below a predetermined value during the period when water is supplied by the water supply unit 44 until the water level in the water tank 33 reaches the predetermined water level, and after the predetermined water level is reached, the resistance between the electrodes may be reduced. When the resistance is lower than a predetermined value, the control unit 57 will perform a draining action through the drain valve 43 .
藉此，控制部57會判定產生了異常發泡，並且可以在將異常發泡之洗滌水暫時排水後進行清洗程序。因此，本實施形態中之滾筒式洗衣機可以區別泡沫偵測部70的短路與異常發泡來進行辨識，並可以適當地處理異常發泡。Thereby, the control unit 57 determines that abnormal foaming has occurred, and can perform the cleaning process after temporarily draining the abnormally foaming wash water. Therefore, the drum-type washing machine in this embodiment can distinguish between a short circuit in the foam detection unit 70 and abnormal foaming, and can appropriately handle the abnormal foaming.
在藉由供水部44而供水至水槽33內的水位到達預定水位為止的期間中，電極間之電阻不低於預定值時，控制部57會執行第1清洗程序。亦可作成為：在藉由供水部44而供水至水槽33內的水位到達預定水位為止的期間中，判定了電極70a、70b間短路時，控制部57不進行由排水閥43所進行之排水動作，而是執行旋轉滾筒31之旋轉數及旋轉時間的至少一個設定得比第1清洗程序更小的第2清洗程序。During the period when the water supply unit 44 supplies water until the water level in the water tank 33 reaches the predetermined water level, when the resistance between the electrodes is not lower than the predetermined value, the control unit 57 executes the first cleaning program. You may make it so that when it is determined that the electrodes 70a, 70b are short-circuited between the water supply part 44 and the water level in the water tank 33 reaching a predetermined water level, the control part 57 does not perform drainage by the drain valve 43. Instead, at least one of the rotation number and the rotation time of the rotating drum 31 is set to be smaller than the first cleaning program.
藉此，可以比正常清洗程序更加抑制因旋轉滾筒31的攪拌所造成之起泡。因此，本實施形態中之滾筒式洗衣機即便在泡沫偵測部短路時，仍可適當地處理異常發泡。Thereby, foaming caused by the stirring of the rotating drum 31 can be suppressed more than in the normal cleaning process. Therefore, the drum-type washing machine in this embodiment can properly handle abnormal foaming even when the foam detection part is short-circuited.
亦可作成為：更具備：顯示部59，用以通知洗滌運轉之狀況，又，在判定了電極70a、70b間短路時，控制部57會在洗滌步驟結束後，藉由顯示部59進行異常通知。It can also be configured as follows: a display unit 59 is used to notify the status of the washing operation. In addition, when it is determined that the short circuit between the electrodes 70a and 70b is determined, the control unit 57 will use the display unit 59 to perform an abnormality detection after the washing step is completed. notify.
藉此，使用者可以認知到泡沫偵測部70並未正常發揮功能。因此，藉由實施洗淨水槽33或旋轉滾筒31本身的行程，使堆積於泡沫偵測部70之電極間的堆積物除去，便可以適當地處理泡沫偵測部的短路。 (其他實施形態)Thereby, the user can recognize that the foam detection part 70 does not function normally. Therefore, by performing the stroke of the washing water tank 33 or the rotating drum 31 itself to remove the deposits accumulated between the electrodes of the foam detection part 70, the short circuit of the foam detection part can be appropriately dealt with. (Other embodiments)
如以上地，作為在本申請案中所揭示之技術的例示，說明了實施形態1，但本揭示中之技術並不限定於此。As mentioned above, Embodiment 1 has been described as an example of the technology disclosed in this application, but the technology disclosed in this application is not limited to this.
因此，以下例示其他實施形態。Therefore, other embodiments are illustrated below.
實施形態1中，作為洗衣機的一例說明了滾筒式洗衣機。洗衣機只要是可以將布水洗之物即可，並不限定於滾筒式洗衣機。因此，亦可為縱型洗衣機，且亦可為二槽式洗衣機。又，實施形態1中，是針對具有乾燥功能之滾筒式洗衣機進行了說明，但不具有乾燥功能之滾筒式洗衣機也可以發揮同樣的效果。又，即便是在電極間因經年變化而短路的情況下，仍可防止泡沫的增大，並同時防止洗淨性能明顯降低。因此，對於需要可以從泡沫等保護電氣零件的防止部的洗淨機等也很有用。In the first embodiment, a drum-type washing machine is explained as an example of the washing machine. The washing machine is not limited to a drum-type washing machine as long as it can wash cloth. Therefore, it can also be a vertical washing machine, and it can also be a two-tank washing machine. Furthermore, in Embodiment 1, a drum-type washing machine with a drying function has been described, but a drum-type washing machine without a drying function can also exhibit the same effect. In addition, even if the electrodes are short-circuited due to changes over time, it can still prevent the increase of foam and prevent the cleaning performance from being significantly reduced. Therefore, it is also useful for washing machines and the like that require a protective portion that can protect electrical parts from foam and the like.
實施形態1中，作為內槽的一例，是使用將軸心方向從正面側朝向背面側向下傾斜配設的旋轉滾筒31來進行了說明。由於內槽只要內包於外槽，並配設成旋轉自如即可，因此配設於水平方向亦可。In Embodiment 1, as an example of an inner tank, the rotating drum 31 which is arrange|positioned so that the axial direction is inclined downward from the front side to the back side was used and was demonstrated. Since the inner tank only needs to be enclosed in the outer tank and arranged to rotate freely, it can also be arranged in the horizontal direction.
實施形態1中，是藉由水位到達h2為止的期間之電阻值的變動來進行短路判定(S102)。然而，到開始運轉為止的期間中，水槽33內的水位就已經成為h2以上時，亦可不執行前述之短路判定(S102)。這是由於無法依順序經過S101及102，導致短路判定本身就欠缺正確性的緣故。在此情況下，由於會有異常發泡的可能性，因此在泡沫偵測部70之電阻值小於閾值時，迅速地進入排水(消泡程序)(S106)亦可。In Embodiment 1, the short-circuit determination is performed based on the change in the resistance value until the water level reaches h2 (S102). However, when the water level in the water tank 33 is equal to or higher than h2 before starting the operation, the aforementioned short circuit determination (S102) does not need to be performed. This is because S101 and S102 cannot be passed in sequence, causing the short circuit determination itself to lack accuracy. In this case, since there is a possibility of abnormal foaming, when the resistance value of the foam detection part 70 is less than the threshold value, it may be quickly entered into the drainage (defoaming process) (S106).
實施形態1中，在S105判定為異常發泡後，是藉由將水槽33內的水排水來處理異常發泡。異常發泡的處理並不限定於將水槽33內的水排水，亦可藉由清洗程序來處理。例如，進行第1弱清洗程序，只要在經過預定時間(例如1分鐘)後泡沫偵測部70所檢測之電阻值在閾值以上，控制部57便判斷電極間沒有泡沫的存在，亦即已消泡亦可。此外，亦可作成為：返回到正常清洗程序(S103)，若泡沫偵測部70所檢測之電阻值仍為小於閾值的狀態，便藉由排水部43將水槽33內的水排水。In Embodiment 1, after it is determined that abnormal foaming occurs in S105, the abnormal foaming is treated by draining the water in the water tank 33. The treatment of abnormal foaming is not limited to draining the water in the water tank 33, and can also be dealt with through a cleaning process. For example, during the first weak cleaning process, as long as the resistance value detected by the foam detection unit 70 is above the threshold after a predetermined time (for example, 1 minute), the control unit 57 determines that there is no foam between the electrodes, that is, it has been eliminated. You can also soak it. In addition, it can also be done as follows: returning to the normal cleaning process (S103), if the resistance value detected by the foam detection part 70 is still less than the threshold value, the water in the water tank 33 is drained through the drainage part 43.
實施形態1中，在S110中進行了第1弱清洗程序。在S110中，亦可作成為進入比第1弱清洗程序更弱的第2弱清洗程序。此處，所謂第2弱清洗程序是指例如將旋轉滾筒31以旋轉5秒後停止10秒之更弱攪拌時間，並且以旋轉數30r/min來進行運轉。第2弱清洗程序由於攪拌比第1弱清洗程序更弱，因此可以更加抑制起泡。當進入了第2弱清洗程序時，為了確保洗淨力，亦可使第2預定時間(S111)比第1預定時間(S107)更長(例如20分鐘)。又，亦可作成為在S103中進行第1弱清洗程序，且在S110中進行第2弱清洗程序。此處，第2弱清洗程序亦稱為第3清洗程序。In Embodiment 1, the first weak cleaning process is performed in S110. In S110, it may also be configured to enter a second weak cleaning program that is weaker than the first weak cleaning program. Here, the second weak cleaning program refers to, for example, a weaker stirring time in which the rotating drum 31 is rotated for 5 seconds and then stopped for 10 seconds, and is operated at a rotation speed of 30 r/min. The second weak cleaning program can suppress foaming even more because the agitation is weaker than the first weak cleaning program. When the second weak cleaning program is entered, in order to ensure the cleaning power, the second predetermined time (S111) can also be made longer (for example, 20 minutes) than the first predetermined time (S107). Alternatively, the first weak cleaning program may be performed in S103, and the second weak cleaning program may be performed in S110. Here, the second weak cleaning process is also called the third cleaning process.
又，實施形態1中，是將正常清洗程序(S103)中之異常發泡判定(S105)的判定值、與短路判定(S109)之判定值一起設為相同閾值(例如，500kΩ)，但並不限於此。將異常發泡判定值設為第1閾值(例如，500kΩ)，並將短路判定值設為第2閾值(例如，250kΩ)等亦可。相較於因洗劑之發泡所造成之正常電阻值的降低程度，以更低之電阻值來作為短路判定的基準，便可以提高短路判定的精確度。Moreover, in Embodiment 1, the determination value of the abnormal foaming determination (S105) in the normal cleaning process (S103) and the determination value of the short circuit determination (S109) are set to the same threshold value (for example, 500 kΩ), but they are not Not limited to this. The abnormal foaming determination value may be set to the first threshold (for example, 500 kΩ), and the short circuit determination value may be set to the second threshold (for example, 250 kΩ). Compared with the reduction in the normal resistance value caused by the foaming of the lotion, using a lower resistance value as the basis for short circuit determination can improve the accuracy of short circuit determination.
又，實施形態1中，水位h2是設為相當於旋轉滾筒31之下端的高度位置的水位，但並不限於此。水位h2只要是比水位h1更低，並且是藉由旋轉滾筒31的旋轉來攪拌包含洗劑成分之洗滌水後不會產生發泡的水位即可。In addition, in Embodiment 1, the water level h2 is set to the water level corresponding to the height position of the lower end of the rotating drum 31, but it is not limited to this. The water level h2 only needs to be lower than the water level h1 and be a water level that does not cause foaming when the washing water containing detergent components is stirred by the rotation of the rotating drum 31 .
又，實施形態1中，是作成為：具備與排水路徑42連通的循環泵80，並使與循環泵80連通的循環路徑81連通於水槽33前方下部的循環口82，來使洗滌步驟中之洗滌水如箭頭b地循環的構成。實施形態1中雖未針對循環泵80的驅動進行說明，但亦可作成如下。亦可作成為：在正常清洗程序(S103)時，提高循環泵80的旋轉數或運作率(例如3500r/min，30秒on-30秒off)，在短路判定(S109)時，為了抑制發泡而減低循環泵80的旋轉數或運作率(例如2500r/min，20秒on-40秒off)，或是使其停止。藉此，可以抑制因循環泵80之驅動而更加地助長異常發泡。Furthermore, in Embodiment 1, the circulation pump 80 connected to the drainage path 42 is provided, and the circulation path 81 connected to the circulation pump 80 is connected to the circulation port 82 in the front and lower part of the water tank 33, so that the washing step can be completed. The wash water circulates as shown by arrow b. Although the driving of the circulation pump 80 is not described in Embodiment 1, it may be configured as follows. It can also be made as follows: during the normal cleaning procedure (S103), the rotation number or operation rate of the circulation pump 80 is increased (for example, 3500r/min, 30 seconds on-30 seconds off), and during the short circuit determination (S109), in order to suppress the occurrence of Soak and reduce the rotation number or operation rate of the circulation pump 80 (for example, 2500 r/min, 20 seconds on-40 seconds off), or stop it. This can prevent abnormal foaming from being further promoted by driving the circulation pump 80 .
另外，由於上述之實施形態是用於例示本揭示中之技術的實施形態，因此在申請專利範圍或其均等範圍中可以進行各種變更、置換、附加、省略等。In addition, since the above-described embodiments are for illustrating the technology in the present disclosure, various changes, substitutions, additions, omissions, etc. may be made within the scope of the claims or their equivalent scope.
本揭示可適用於洗滌衣物之洗衣機。具體而言，本揭示可適用於縱型洗衣機、滾筒式洗衣機、二槽式洗衣機等。This disclosure can be applied to washing machines for washing clothes. Specifically, the present disclosure is applicable to vertical washing machines, drum washing machines, two-tank washing machines, etc.
