Description

洗衣機(一)Washing machine (1) 技術領域Technical field

本發明係有關於一種可快速且正確地感測洗滌液之起泡程度之洗衣機。The present invention relates to a washing machine that can quickly and correctly sense the degree of foaming of a washing liquid.

背景技術Background technique

洗滌作業中，洗滌液之起泡程度為重要參數。例如，當洗滌液之起泡程度高時，必須增加用以沖洗洗滌物之水量。另一方面，當起泡程度小時，由節約水資源之觀點來看，宜減少用以沖洗洗滌物之水量。The degree of foaming of the washing liquid is an important parameter in the washing operation. For example, when the degree of foaming of the washing liquid is high, the amount of water used to rinse the laundry must be increased. On the other hand, when the degree of foaming is small, it is desirable to reduce the amount of water used to rinse the laundry from the viewpoint of saving water resources.

日本特開2009-28113號公報揭示一種洗衣機，係藉由驅動洗滌槽，使洗滌液之泡導入設置於光感測器附近之導水溝內，然後根據該泡到消失期間之光透過率的時間變化，來判定起泡程度。Japanese Laid-Open Patent Publication No. 2009-28113 discloses a washing machine in which a bubble of a washing liquid is introduced into a water guiding groove provided near a photosensor by driving a washing tank, and then according to the light transmittance of the bubble during the disappearance period Change to determine the degree of foaming.

日本特開2009-28113號公報所揭示之手法為了判定起泡，必須等到導入至導水溝內之泡消失為止。因此，到判定起泡程度為止需要較長的時間。因此，當清洗時間較短時，會有無法判定起泡程度之問題。又，當洗滌中補給水時，由於光透過率產生變化，因此會有無法正確地判定起泡程度的問題。In order to determine the foaming, the method disclosed in Japanese Laid-Open Patent Publication No. 2009-28113 must wait until the bubble introduced into the water guiding groove disappears. Therefore, it takes a long time until the degree of foaming is determined. Therefore, when the cleaning time is short, there is a problem that the degree of foaming cannot be determined. Further, when the water is supplied during washing, since the light transmittance changes, there is a problem that the degree of foaming cannot be accurately determined.

導電度感測器包含突出於洗滌液中之一對電極。藉由在電極間施加高頻電壓，感測洗滌液之電阻變化。因此，接近於光感測器而配置之導電度感測器會擾亂在管路流動之洗滌液之液流，使光感測器之感測信號不安定。The conductivity sensor includes a pair of electrodes that protrude from the wash liquid. The resistance change of the washing liquid is sensed by applying a high frequency voltage between the electrodes. Therefore, the conductivity sensor disposed close to the photo sensor disturbs the flow of the washing liquid flowing in the pipeline, so that the sensing signal of the photo sensor is unstable.

本發明之目的即在於提供一種可快速且正確地感測洗滌液之起泡程度之洗衣機。It is an object of the present invention to provide a washing machine that can quickly and accurately sense the degree of foaming of a washing liquid.

本發明之一觀點之洗衣機的特徵在於包含有：洗滌槽，係具有供洗滌液流入之流入口、及供前述洗滌液排出之排出口者；管路，係連接於前述流入口與前述排出口者；流動裝置，係使前述洗滌液通過該管路而由前述排出口朝前述流入口流動者；光感測器，係檢測通過前述管路內之洗滌液之光量者；及控制部，係根據前述光感測器之檢測信號，控制洗滌動作者，其中前述光感測器係用以檢測並輸出前述流動裝置運轉期間之第1光量與前述流動裝置停止期間之第2光量。A washing machine according to one aspect of the present invention includes a washing tank having an inflow port through which a washing liquid flows in, and a discharge port for discharging the washing liquid; and a pipe connected to the inflow port and the discharge port The flow device is configured to pass the washing liquid through the pipe to the inlet port through the discharge port; the light sensor detects the amount of light passing through the washing liquid in the pipe; and the control unit The washing actor is controlled according to the detection signal of the photo sensor, wherein the photo sensor is configured to detect and output the first light amount during the operation of the flow device and the second light amount during the stop of the flow device.

Further, the principle described below is not limited to the drum type washing machine shown in Fig. 1, and may be applied to other washing machines (for example, a pulsating pump type washing machine or a stirring type washing machine).

滾筒式洗衣機1具有筐體2。筐體2之內部配設有洗滌槽3。洗滌槽3包含：可自由搖動地支持於筐體2之內部之圓筒狀水槽31、可自由旋轉地支持於水槽31內之圓筒狀旋轉滾筒32、及使旋轉滾筒32旋轉之馬達33。水槽31及旋轉滾筒32各自具有底部。馬達330安裝於水槽31之底部外面。水槽31形成有用以排出洗滌液之排出口311及供洗滌液流入之流入口312。洗滌液由排出口311往流入口312循環。The drum type washing machine 1 has a casing 2. A washing tub 3 is disposed inside the casing 2. The washing tub 3 includes a cylindrical water tank 31 that is rotatably supported inside the casing 2, a cylindrical rotating drum 32 that is rotatably supported in the water tank 31, and a motor 33 that rotates the rotating drum 32. The water tank 31 and the rotary drum 32 each have a bottom. The motor 330 is mounted outside the bottom of the water tank 31. The water tank 31 forms a discharge port 311 for discharging the washing liquid and an inflow port 312 through which the washing liquid flows. The washing liquid is circulated from the discharge port 311 to the inflow port 312.

筐體2進而收容有：往水槽31內供水之供水系統4、使水槽31內之洗滌液進行排水或循環之排水系統5、及將用以使洗滌物乾燥之溫風送入洗滌槽3之乾燥系統6。再者，乾燥系統6未必為必要者。Further, the casing 2 houses a water supply system 4 that supplies water into the water tank 31, a drainage system 5 that drains or circulates the washing liquid in the water tank 31, and a warm air for drying the laundry into the washing tub 3. Drying system 6. Furthermore, the drying system 6 is not necessarily necessary.

乾燥系統6包含有循環管路61，循環管路61具有與水槽31之排氣口313連接之一端部、及用以由水槽31之底部送入乾燥用空氣之通氣口。乾燥系統6更包含配設於循環管路61之內部之送風機62。送風機62係使空氣在循環管路61內流動。乾燥系統6亦可因應必要而含有：用以收集線屑類並且進行除塵之過濾器、用以將除塵後之導入空氣除濕之除濕部、及用以加熱除塵後之空氣並且作出已乾燥之高溫空氣之加熱部。The drying system 6 includes a circulation line 61 having one end connected to the exhaust port 313 of the water tank 31 and a vent for feeding the drying air from the bottom of the water tank 31. The drying system 6 further includes a blower 62 disposed inside the circulation line 61. The blower 62 causes air to flow in the circulation line 61. The drying system 6 may also contain, as necessary, a filter for collecting the dust and dust, a dehumidifying portion for dehumidifying the introduced air after dust removal, and a device for heating the dust-removed air and making the dried high temperature. The heating part of the air.

滾筒式洗衣機1具有配設於筐體2之前面之上部之操作面板8。操作面板8係可令使用者選擇滾筒式洗衣機1之運轉排程之模式或各種機能。操作面板8包含控制電路部81。控制電路部81係將使用者輸入之資訊顯示於操作面板8具有之顯示部。又，控制電路部81亦可由例如作為用以感測水槽31內之液位之液位感測器、使用作為用以感測洗滌液之濁度之濁度感測器之光感測器72、或使用作為用以感測洗滌液之導電度之導電感測器之電極感測器73接收感測信號。透過操作面板8設定滾筒式洗衣機1之運轉開始時，控制電路部81根據該等感測信號，控制供水系統統4所含之電磁閥或排水系統5所含之排水閥75。由控制電路部81自動控制之馬達33、供水系統統4、排水系統5及乾燥系統6依據模式設定或控制程式，共同動作後執行至少清洗步驟、沖洗步驟、脫水步驟及乾燥步驟。The drum type washing machine 1 has an operation panel 8 disposed above the front surface of the casing 2. The operation panel 8 allows the user to select the mode of operation scheduling of the drum type washing machine 1 or various functions. The operation panel 8 includes a control circuit unit 81. The control circuit unit 81 displays the information input by the user on the display unit of the operation panel 8. Further, the control circuit unit 81 may be used, for example, as a liquid level sensor for sensing the liquid level in the water tank 31, and as a light sensor 72 for sensing the turbidity of the washing liquid. The sensing signal is received by the electrode sensor 73 as a conductive sensor for sensing the conductivity of the washing liquid. When the operation of the drum type washing machine 1 is started by the operation panel 8, the control circuit unit 81 controls the drain valve 75 included in the solenoid valve or the drain system 5 included in the water supply system 4 based on the sensing signals. The motor 33, the water supply system 4, the drainage system 5, and the drying system 6 automatically controlled by the control circuit unit 81 perform at least a washing step, a rinsing step, a dehydrating step, and a drying step in accordance with a mode setting or a control program.

供水系統統4包含：與水槽31連接之供水管路41、及用以收容洗劑之洗劑收容部42。供水系統統4可藉由電磁閥之開關動作而經由供水管路41適時地供水到水槽31(參照第1圖中實線箭頭)。又，第1圖所示之滾筒式洗衣機1利用供水系統統4之供水，將部分橫切供水管路41而配設之洗劑收容部42內之洗劑適時地投入到水槽31內。The water supply system 4 includes a water supply line 41 connected to the water tank 31, and a lotion storage unit 42 for containing a lotion. The water supply system 4 can timely supply water to the water tank 31 via the water supply line 41 by the switching operation of the electromagnetic valve (refer to the solid arrow in Fig. 1). Further, the drum-type washing machine 1 shown in Fig. 1 uses the water supply of the water supply system 4 to timely introduce the lotion in the lotion storage portion 42 disposed partially across the water supply line 41 into the water tank 31.

排水系統5包含：具有與水槽31之排出口311連接之一端部之第1管路51、及與第1管路51之他端部連接之排水控制單元7。排水控制單元7係承接來自水槽31之洗滌液。排水系統5更進一步包含：在排水控制單元7具有之循環泵71與水槽31之間延伸之第2管路52。滾筒式洗衣機1之循環泵71固定於底座712。第2管路52之一端部係連接於循環泵71之吐出口。又，第2管路52之他端部連接於水槽31之流入口312。水槽31、第1管路51、排水控制單元7及第2管路52形成洗滌液之循環路。循環泵71係使洗滌液在循環路內由排出口311朝向流入口312流動、循環。The drainage system 5 includes a first line 51 having one end connected to the discharge port 311 of the water tank 31, and a drain control unit 7 connected to the other end of the first line 51. The drain control unit 7 receives the washing liquid from the water tank 31. The drainage system 5 further includes a second conduit 52 extending between the circulation pump 71 and the water tank 31 of the drainage control unit 7. The circulation pump 71 of the drum type washing machine 1 is fixed to the base 712. One end of the second conduit 52 is connected to the discharge port of the circulation pump 71. Further, the other end of the second conduit 52 is connected to the inflow port 312 of the water tank 31. The water tank 31, the first line 51, the drain control unit 7, and the second line 52 form a circulation path of the washing liquid. The circulation pump 71 causes the washing liquid to flow and circulate through the discharge port 311 toward the inflow port 312 in the circulation path.

排水控制單元7除了循環泵71之外，還具有：作為感測洗滌液濁度之濁度感測器使用之光感測器72、作為感測洗滌液導電度之導電感測器使用之電極感測器73、用以將洗滌液排到外部之排水管路74、及配設於排水管路74之中途部之排水閥75。排水閥75用以開關排水管路74。排水控制單元7更包含用以收集由第1管路51流入之洗滌液所含之棉纖維(棉屑等)之過濾部76。The drain control unit 7 has, in addition to the circulation pump 71, a photo sensor 72 used as a turbidity sensor for sensing the turbidity of the washing liquid, and an electrode used as a conductive sensor for sensing the conductivity of the washing liquid. The sensor 73 has a drain line 74 for discharging the washing liquid to the outside, and a drain valve 75 disposed at the middle of the drain line 74. The drain valve 75 is used to open and close the drain line 74. The drain control unit 7 further includes a filter unit 76 for collecting cotton fibers (cotton chips, etc.) contained in the washing liquid flowing in the first line 51.

排水閥75係在例如清洗步驟結束時或沖洗步驟結束時開啟。其結果是，洗滌液會自第1管路51流入到排水控制單元7。然後，洗滌液通過過濾部76而施行棉纖維之除去處理後排出到外部。The drain valve 75 is opened, for example, at the end of the washing step or at the end of the flushing step. As a result, the washing liquid flows into the drain control unit 7 from the first line 51. Then, the washing liquid is subjected to removal treatment of the cotton fibers through the filter portion 76, and then discharged to the outside.

當排水閥75關閉並且循環泵71作動時，水槽31內之洗滌液會通過第1管路51而流入到排水控制單元7。然後，洗滌液通過配設於排水控制單元7內之過濾部76，除去髒汙成分。通過過濾部76之洗滌液會通過連接於循環泵71之吸引口之吸引管路711而流入到循環泵71內。然後，洗滌液會通過連接到循環泵71之吐出口之第2管路52而回到水槽31內。在執行清洗步驟或沖洗步驟期間，亦可視需要而反覆進行上述之洗滌液的循環。洗滌液之反覆循環會提供於品質高之清洗步驟或沖洗步驟。When the drain valve 75 is closed and the circulation pump 71 is actuated, the washing liquid in the water tank 31 flows into the drain control unit 7 through the first line 51. Then, the washing liquid passes through the filter portion 76 disposed in the drain control unit 7, and the dirty component is removed. The washing liquid that has passed through the filter unit 76 flows into the circulation pump 71 through the suction line 711 connected to the suction port of the circulation pump 71. Then, the washing liquid is returned to the water tank 31 through the second line 52 connected to the discharge port of the circulation pump 71. The circulation of the above washing liquid may also be repeated as needed during the washing step or the rinsing step. The recirculation of the wash liquor is provided in a high quality wash or rinse step.

循環泵71之旋轉數亦可改變。當循環泵71之旋轉數設定較高時(例如，3500rpm)，流入到水槽31之流入口312之洗滌液會順著朝向旋轉滾筒32內之軌跡而移動(參照第1圖中箭頭Fi)。另一方面，循環泵71之旋轉數設定較低時(例如，1000rpm)，流入到水槽31之流入口312之洗滌液會朝向在旋轉滾筒32與水槽31之間形成的空間內(參照第1圖中箭頭Fo)。The number of rotations of the circulation pump 71 can also be changed. When the number of rotations of the circulation pump 71 is set high (for example, 3500 rpm), the washing liquid flowing into the inlet 312 of the water tank 31 moves along the trajectory toward the inside of the rotary drum 32 (refer to arrow Fi in Fig. 1). On the other hand, when the number of rotations of the circulation pump 71 is set low (for example, 1000 rpm), the washing liquid flowing into the inlet 312 of the water tank 31 faces the space formed between the rotary drum 32 and the water tank 31 (refer to the first Arrow Fo in the figure.

循環泵71在例如清洗步驟與沖洗步驟中之至少1個步驟開始時，進行低速旋轉。其結果是，可抑制洗滌結束時溶解殘留之洗劑或柔軟劑投入後之高濃度柔軟劑落下到旋轉滾筒32內之洗滌物。The circulation pump 71 performs low-speed rotation at the start of at least one of the washing step and the rinsing step, for example. As a result, it is possible to suppress the washing of the high-concentration softening agent which has been dissolved in the rotating drum 32 after the washing agent or the softening agent which has been dissolved at the end of washing.

流入到旋轉滾筒32與水槽31之間之空間的洗滌液會自排出口311朝排水系統5排出，並且再次回到水槽31之流入口312(水槽內循環步驟)。藉由反覆進行水槽內循環步驟，促進洗劑之溶解，及/或柔軟劑之濃度之均一化。而且，可適當避免溶解殘留之洗劑或高濃度之柔軟劑造成洗滌物之印漬等問題。The washing liquid that has flowed into the space between the rotary drum 32 and the water tank 31 is discharged from the discharge port 311 toward the drainage system 5, and is returned to the inlet 312 of the water tank 31 again (the circulation step in the water tank). The dissolution of the lotion and/or the homogenization of the concentration of the softening agent are promoted by repeating the step of circulating in the water tank. Moreover, it is possible to appropriately avoid the problem of dissolving the residual lotion or the high concentration of the softening agent to cause the printing of the laundry.

水槽內循環步驟宜在例如清洗步驟及/或沖洗步驟中之供水步驟約10秒後設定。取而代之，水槽內循環步驟亦可在例如感測由水槽31之下端起算約40mm之液位時才開始。其結果是，可適當避免洗滌液未充分充滿於循環泵71內之期間之循環泵71的作動。而且，可避免循環泵71之空洞現象(cavitation)造成之怪音、不足之洗滌液量造成之循環泵71之異常溫度以及在異常溫度下之循環泵71的作動。The circulation step in the water tank is preferably set after about 10 seconds of the water supply step in the washing step and/or the rinsing step, for example. Alternatively, the circulation step in the water tank can also be started, for example, when sensing a liquid level of about 40 mm from the lower end of the water tank 31. As a result, the operation of the circulation pump 71 during the period in which the washing liquid is not sufficiently filled in the circulation pump 71 can be appropriately avoided. Further, it is possible to avoid the strange noise caused by the cavitation of the circulation pump 71, the abnormal temperature of the circulation pump 71 caused by the insufficient amount of the washing liquid, and the operation of the circulation pump 71 at the abnormal temperature.

滾筒式洗衣機1進而亦可具有用以將洗澡水供給往水槽31之泵。泵亦可在將洗澡水供給到水槽31後，執行水槽內循環步驟。而且，洗澡水供給用之泵與循環泵71不同時動作，可抑制令使用者感到不愉快之大噪音。The drum type washing machine 1 may further have a pump for supplying bath water to the water tank 31. The pump may also perform a circulation step in the water tank after supplying the bath water to the water tank 31. Further, the pump for supplying the bath water does not operate at the same time as the circulation pump 71, and it is possible to suppress a large noise which is unpleasant to the user.

亦可透過操作面板8之操作而對滾筒式洗衣機1設定預約運轉。滾筒式洗衣機1進行預約運轉時，水槽內循環步驟亦可在例如一般時間之2倍長的期間進行。其結果是，可適當地溶解在預約待機中(進行預約設定後到滾筒式洗衣機1實際開始動作之期間)固化之洗劑。而且，預約運轉期間，可得到充分的洗淨力並且可減少未溶解之洗劑量。The scheduled operation of the drum type washing machine 1 can also be set by the operation of the operation panel 8. When the drum type washing machine 1 performs the scheduled operation, the circulation step in the water tank may be performed for a period of, for example, twice the normal time. As a result, it is possible to appropriately dissolve the lotion which is solidified in the reservation standby (during the time when the reservation setting is made until the drum type washing machine 1 actually starts to operate). Moreover, during the scheduled operation, sufficient detergency can be obtained and the amount of undissolved washing can be reduced.

滾筒式洗衣機1亦可視需要而具有溫度感測器。因應於使用溫度感測器所測定之洗滌液之溫度，改變水槽內循環步驟之長度。例如，當溫度感測器感測到5℃之洗滌液之溫度時，則執行例如感測到20℃之洗滌液之溫度時之倍數之長度的水槽內循環步驟。其結果是，即使在低水溫下也可充分溶解洗劑。The drum type washing machine 1 also has a temperature sensor as needed. The length of the circulation step in the water tank is changed in response to the temperature of the washing liquid measured by the temperature sensor. For example, when the temperature sensor senses the temperature of the washing liquid of 5 ° C, an in-tank circulation step of, for example, a length that senses the temperature of the washing liquid of 20 ° C is performed. As a result, the lotion can be sufficiently dissolved even at a low water temperature.

The flat inner surface 772 extends from the middle of the straight tube portion 701 toward the downstream storage tube portion 702. A flat inner surface 772 extending through a horizontal plane passing through the central axis of the straight tube portion 701 forms a flat strip-shaped region that extends toward the receiving tube portion 702. The flat inner surface 772 of the light sensor 72 for light exiting and receiving light prevents unwanted refraction of the infrared light used by the light sensor 72.

直管部701形成有一對貫通孔773。貫通孔773插通有電極感測器73。電極感測器73之電極部係突出於直管部701內，且與直管部701包覆於其內之洗滌液接觸。The straight pipe portion 701 is formed with a pair of through holes 773.

光感測器72包含：出射紅外光線之發光元件721、及接收由發光元件721出射之紅外光線之受光元件722。配設於直管部701之外側之發光元件721及受光元件722係互相對向成在發光元件721與受光元件722之間形成紅外光線之光路。直管部701係由使紅外光線透過之材料形成。來自發光元件721之紅外光線通過充滿於由直管部701之管壁部所包圍之空間內之洗滌液中。洗滌液之濁度大時，到達受光元件722之紅外光線之光量會變小，另一方面，當洗滌液之濁度小時，到達受光元件722之紅外光線之光量會變大。而且，光感測器72發揮作為用以感測洗滌液之濁度之濁度感測器的功能。The photo sensor 72 includes a light-emitting element 721 that emits infrared light, and a light-receiving element 722 that receives infrared light emitted from the light-emitting element 721. The light-emitting element 721 and the light-receiving element 722 disposed on the outer side of the straight tube portion 701 are opposed to each other to form an optical path of infrared light between the light-emitting element 721 and the light-receiving element 722. The straight tube portion 701 is formed of a material that transmits infrared light. The infrared light from the light-emitting element 721 passes through the washing liquid filled in the space surrounded by the tube wall portion of the straight tube portion 701. When the turbidity of the washing liquid is large, the amount of infrared light reaching the light receiving element 722 becomes small. On the other hand, when the turbidity of the washing liquid is small, the amount of infrared light reaching the light receiving element 722 becomes large. Moreover, the photo sensor 72 functions as a turbidity sensor for sensing the turbidity of the washing liquid.

光感測器72進而更具有用以保持發光元件721及受光元件722之支持體723。具有略U字形之截面之支持體723包含：用以支持發光元件721之第1支持部724、用以支持受光元件722之第2支持部725、及使第1支持部724與第2支持部725連結之架橋部726。架橋部726係保持在發光元件721與受光元件722互相對向之位置。直管部701上之架橋部726係相對於直管部701之軸呈直角延伸。The photo sensor 72 further has a support 723 for holding the light-emitting element 721 and the light-receiving element 722. The support 723 having a substantially U-shaped cross section includes a first support portion 724 for supporting the light-emitting element 721, a second support portion 725 for supporting the light-receiving element 722, and a first support portion 724 and a second support portion. 725 connected bridge portion 726. The bridge portion 726 is held at a position where the light-emitting element 721 and the light-receiving element 722 oppose each other. The bridging portion 726 on the straight tube portion 701 extends at a right angle to the axis of the straight tube portion 701.

第1支持部724內除了發光元件721，還配置有用以使紅外光線由發光元件721出射之電路基板727。第2支持部725內除了受光元件722之外，還配置有用以因應於受光元件722所接收之紅外光線之光量而生成電壓信號之電路基板728。進而，光感測器72包含用以電力供給至電路基板727、728之電線729。薄板形狀之電路基板727、728(參照第7圖及第8圖)之長向方向軸係朝上下方向延伸。In addition to the light-emitting element 721, the first support portion 724 is provided with a circuit board 727 for emitting infrared light from the light-emitting element 721. In the second support portion 725, in addition to the light receiving element 722, a circuit board 728 for generating a voltage signal in response to the amount of infrared light received by the light receiving element 722 is disposed. Further, the photo sensor 72 includes an electric wire 729 for supplying electric power to the circuit boards 727, 728. The long-axis directions of the thin-plate-shaped circuit boards 727 and 728 (see FIGS. 7 and 8) extend in the vertical direction.

第1支持部724具有與第2支持部725相對向之內側面241。內側面241包含發光元件721之透鏡部211。由發光元件721出射之紅外光線通過透鏡部211而朝向第2支持部725。透鏡部211係相對內側面241之其他部份稍微***。沿著朝內側面241之上下方向延伸之邊緣而形成第1肋242。第1肋242由內側面241突出於內方(直管部701之中心軸方向)。The first support portion 724 has an inner side surface 241 that faces the second support portion 725 . The inner side surface 241 includes a lens portion 211 of the light emitting element 721. The infrared ray emitted from the light-emitting element 721 passes through the lens portion 211 and faces the second support portion 725. The lens portion 211 is slightly raised relative to other portions of the inner side surface 241. The first rib 242 is formed along the edge extending in the upper direction toward the inner side surface 241. The first rib 242 protrudes from the inner side surface 241 to the inner side (the direction of the central axis of the straight tube portion 701).

第2支持部725具有與第1支持部724相對向之內側面251。內側面251包含受光元件722之透鏡部221。由發光元件721出射之紅外光線通過透鏡部221而到達受光元件722。透鏡部221係相對內側面251之其他部份稍微***。沿著朝內側面251之上下方向延伸之邊緣形成第2肋252。第2肋252係由內側面251突出於內方(直管部701之中心軸方向)。The second support portion 725 has an inner side surface 251 that faces the first support portion 724 . The inner side surface 251 includes a lens portion 221 of the light receiving element 722. The infrared ray emitted from the light-emitting element 721 passes through the lens portion 221 and reaches the light-receiving element 722. The lens portion 221 is slightly raised relative to other portions of the inner side surface 251. The second rib 252 is formed along the edge extending in the upper direction toward the inner side surface 251. The second rib 252 protrudes from the inner side surface 251 to the inner side (the direction of the central axis of the straight tube portion 701).

形成平坦內面772之直管部701之管壁部份的外面也形成平坦狀。因此，由發光元件721出射之紅外光線不會因直管部701之兩壁面而有不必要之折射。支持體723係由上方朝向直管部701外嵌。發光元件721係由直管部701外部出射紅外光線。受光元件722係在直管部701外部接收紅外光線。當支持體723與直管部701嵌合時，第1支持部724之第1肋242及第2支持部725之第2肋252會抵接於直管部701之平坦外面。第1肋242及第2肋252由直管部701之平坦而離開第1支持部724及第2支持部725之內側面241、251。其結果是，可抑制支持體723與直管部701嵌合所造成之透鏡部211、221及直管部701之損害。因此，亦可將肋242、252與直管部701之外面之間的壓力(嵌合力)設定較高。而且，支持體723可堅固地安裝於直管部701。The outer surface of the tube wall portion of the straight tube portion 701 forming the flat inner surface 772 is also formed into a flat shape. Therefore, the infrared light emitted from the light-emitting element 721 is not refracted by the two wall surfaces of the straight tube portion 701. The support body 723 is externally fitted from the upper side toward the straight tube portion 701. The light-emitting element 721 emits infrared light from the outside of the straight tube portion 701. The light receiving element 722 receives infrared light outside the straight tube portion 701. When the support body 723 is fitted to the straight tube portion 701, the first rib 242 of the first support portion 724 and the second rib 252 of the second support portion 725 abut against the flat outer surface of the straight tube portion 701. The first rib 242 and the second rib 252 are separated from the inner side surfaces 241 and 251 of the first support portion 724 and the second support portion 725 by the straight portion 701. As a result, damage to the lens portions 211 and 221 and the straight tube portion 701 caused by the fitting of the support 723 and the straight tube portion 701 can be suppressed. Therefore, the pressure (fitting force) between the ribs 242 and 252 and the outer surface of the straight pipe portion 701 can be set to be high. Moreover, the support body 723 can be firmly mounted to the straight tube portion 701.

支持體723之架橋部726之中央部形成有朝上下方向延伸之環狀收容壁261。環狀收容壁261形成有形成架橋部726之上面之承板262以及圓柱形狀之收容空間263。承板262形成有貫通孔264。貫通孔264連通於收容空間263。直管部701具有朝上方延伸之圓柱形狀之突出部265。當支持體723與直管部701之嵌合完成時，突出部265***到收容空間263，並且突出部265之上面抵接於承板262之下面。突出部265形成有朝下方延伸之螺孔。插通至承板262之貫通孔264之螺絲與突出部265之螺孔螺合。而且，支持體723會牢固地固定於直管部701。在發光元件721及受光元件722之上方橫跨之承板262可承接朝向安裝有支持體723之直管部701之部份的塵埃或水滴等落下物。An annular receiving wall 261 extending in the vertical direction is formed in a central portion of the bridge portion 726 of the support body 723. The annular receiving wall 261 is formed with a receiving plate 262 that forms an upper surface of the bridging portion 726 and a cylindrical receiving space 263. The carrier plate 262 is formed with a through hole 264. The through hole 264 is in communication with the accommodating space 263. The straight pipe portion 701 has a cylindrical protruding portion 265 that extends upward. When the fitting of the support body 723 and the straight tube portion 701 is completed, the protruding portion 265 is inserted into the accommodating space 263, and the upper surface of the protruding portion 265 abuts against the underside of the receiving plate 262. The protruding portion 265 is formed with a screw hole extending downward. The screw inserted into the through hole 264 of the receiving plate 262 is screwed with the screw hole of the protruding portion 265. Further, the support body 723 is firmly fixed to the straight tube portion 701. The receiving plate 262 that straddles the light-emitting element 721 and the light-receiving element 722 can receive falling objects such as dust or water droplets toward a portion of the straight tube portion 701 on which the support body 723 is attached.

再度參照第2圖至第6圖。相對光感測器72配設於稍微下游側之排水閥75可經由排水管路74連結於排水控制單元7之筐體70。當排水閥75開啟時，直管部701及與包覆於收容管部702內之洗滌液係通過排水管路74而排水到外部。排水管路74與筐體70之連接位置可作為收容管部702之基端部附近。其結果是，藉由開啟排水閥75，在收容管部702以及收容管部702與直管部701之連接部周邊，會產生與循環泵71作動時逆向的洗滌液之液流。Referring again to Figures 2 through 6. The drain valve 75 disposed on the slightly downstream side of the photosensor 72 can be coupled to the casing 70 of the drain control unit 7 via the drain line 74. When the drain valve 75 is opened, the straight pipe portion 701 and the washing liquid contained in the accommodating pipe portion 702 are drained to the outside through the drain pipe 74. The connection position of the drain line 74 and the casing 70 can be made near the base end portion of the housing tube portion 702. As a result, by opening the drain valve 75, a flow of the washing liquid that is reversed when the circulation pump 71 is actuated is generated around the connection portion between the storage tube portion 702 and the storage tube portion 702 and the straight tube portion 701.

電極感測器73配設於比排水管路74與收容管部702之連接位置更稍微靠近下游側。電極感測器73配置於比光感測器72更靠近下游側。光感測器72可作為用以感測洗滌液濁度之濁度感測器的機能。電極感測器73可作為用以感測洗滌液導電度之導電感測器的機能。The electrode sensor 73 is disposed closer to the downstream side than the connection position between the drain line 74 and the housing tube portion 702. The electrode sensor 73 is disposed closer to the downstream side than the photo sensor 72. The photo sensor 72 can function as a turbidity sensor for sensing the turbidity of the washing liquid. The electrode sensor 73 can function as a conductive sensor for sensing the conductivity of the washing liquid.

電極感測器73具有一對端子板731、732。端子板732配設於比端子板731靠近下游側。兩端子板731、732各自連接電線733，並對端子板731、732供給高頻交流電壓。施加之電壓之頻率以及振幅只要是可測定洗滌液之導電度者即可，沒有特別限定。The electrode sensor 73 has a pair of terminal plates 731, 732. The terminal block 732 is disposed on the downstream side of the terminal block 731. The two terminal plates 731 and 732 are each connected to the electric wire 733, and the high frequency alternating voltage is supplied to the terminal plates 731 and 732. The frequency and the amplitude of the applied voltage are not particularly limited as long as the conductivity of the washing liquid can be measured.

第10圖係端子板731之概略圖。第10(a)圖係端子板731之側面圖。第10(b)圖係端子板731之正面圖。與第10圖一併參照第3圖及第6圖。再者，關於第2圖至第6圖所說明之下游之端子板732可作成與端子板731為同樣形狀與大小。Fig. 10 is a schematic view of a terminal block 731. Fig. 10(a) is a side view of the terminal block 731. Fig. 10(b) is a front view of the terminal block 731. Referring to Fig. 10 together, reference is made to Figs. 3 and 6. Further, the terminal plate 732 downstream of the second to sixth drawings can be formed in the same shape and size as the terminal block 731.

端子板731係由1個金屬板形成。端子板731構成撓曲構造。以朝上下方向延伸之撓曲線734為邊界，端子板731之邊緣部735、736朝同方向撓曲。因此，相對於橫切撓曲線734之繞著軸的彎曲力矩，端子板731具有高剛性。端子板731之上部形成有與電線733連接之連接部737。The terminal block 731 is formed of one metal plate. The terminal block 731 constitutes a flex structure. The edge portions 735 and 736 of the terminal block 731 are deflected in the same direction with the deflection curve 734 extending in the vertical direction as a boundary. Therefore, the terminal plate 731 has high rigidity with respect to the bending moment about the axis of the transverse bending curve 734. A connection portion 737 connected to the electric wire 733 is formed at an upper portion of the terminal block 731.

在端子板731之與邊緣部735、736之撓曲方向為相反側之面上形成圓板狀之較厚部738及圓柱狀之電極部739。端子板731經由較厚部738而連接於電極部739之基端部。O環371嵌合於電極部739之基端部。電極部739***至形成於排水控制單元7之筐體70之直管部701的貫通孔773(參照第2圖)。A thick portion 738 having a disk shape and a cylindrical electrode portion 739 are formed on the surface of the terminal plate 731 opposite to the deflection direction of the edge portions 735 and 736. The terminal plate 731 is connected to the base end portion of the electrode portion 739 via the thick portion 738. The O-ring 371 is fitted to the base end portion of the electrode portion 739. The electrode portion 739 is inserted into the through hole 773 formed in the straight tube portion 701 of the casing 70 of the drainage control unit 7 (see Fig. 2).

端子板731形成一對貫通孔310。其中一貫通孔310係相對於電極部739位於上方。另一貫通孔310係相對於電極部739位於下方。一對貫通孔310及電極部739係整齊排列於上下方向。撓曲線734係相對於連結一對貫通孔310之中心點之線平行。貫通孔310***稱為螺栓之固定具。而且，貫通孔310係作為端子板731安裝於直管部701之外面之固定部的機能。The terminal block 731 forms a pair of through holes 310. One of the through holes 310 is located above the electrode portion 739. The other through hole 310 is located below the electrode portion 739. The pair of through holes 310 and the electrode portion 739 are aligned in the vertical direction. The deflection curve 734 is parallel to a line connecting the center points of the pair of through holes 310. The through hole 310 is inserted into a fixture called a bolt. Further, the through hole 310 functions as a fixing portion of the terminal plate 731 attached to the outer surface of the straight tube portion 701.

使用固定具，藉由端子板731往直管部701之外面的壓接，安裝於電極部739之基端部之O環371會受到壓縮。O環371之復元力及插通至貫通孔310之固定具使端子板731產生彎曲力矩。端子板731之左右緣係沿著沿一對貫通孔310之整齊排列方向延伸之撓曲線而撓曲，藉此端子板731對彎曲力矩具有高剛性。因此，端子板731堅固地安裝於直管部701之外面。其結果是，配設於電極部739之基端部之O環371受到強力壓縮，發揮高密封性能。而且，透過形成於直管部701之貫通孔773，可適當地抑制洗滌液漏出。再者，本實施形態中，撓曲線734係與彎曲力矩之軸正交，但撓曲線734與彎曲力矩之軸的交叉角度沒有特別限定。又，本實施形態中，係揭示貫通孔310作為固定部，但亦可使用其他固定手法取而代之，例如，使用夾具而將端子板731壓接於直管部701之外壁之固定手法或以可使O環發揮密封機能之充分的力量使端子板731壓接於直管部701之外壁。再者，使用夾具時，挾持於夾具之端子板731的部份作為固定部之機能。With the fixing tool, the O-ring 371 attached to the base end portion of the electrode portion 739 is compressed by the terminal plate 731 being pressed against the outer surface of the straight tube portion 701. The recovery force of the O-ring 371 and the fixture inserted into the through-hole 310 cause the terminal plate 731 to generate a bending moment. The left and right edges of the terminal block 731 are bent along a deflection curve extending in the alignment direction of the pair of through holes 310, whereby the terminal plate 731 has high rigidity against bending moment. Therefore, the terminal block 731 is firmly attached to the outer surface of the straight tube portion 701. As a result, the O-ring 371 disposed at the base end portion of the electrode portion 739 is strongly compressed and exhibits high sealing performance. Further, the through hole 773 formed in the straight tube portion 701 can appropriately prevent the washing liquid from leaking out. Further, in the present embodiment, the deflection curve 734 is orthogonal to the axis of the bending moment, but the angle of intersection between the deflection curve 734 and the axis of the bending moment is not particularly limited. Further, in the present embodiment, the through hole 310 is disclosed as the fixing portion. Alternatively, other fixing methods may be used instead, and for example, a fixing means for crimping the terminal plate 731 to the outer wall of the straight tube portion 701 using a jig may be used. The O-ring exerts sufficient force of the sealing function to crimp the terminal plate 731 to the outer wall of the straight pipe portion 701. Further, when the jig is used, the portion of the terminal plate 731 held by the jig is used as a function of the fixing portion.

第11圖係安裝有端子板731、732之直管部701的截面圖。第11(a)圖係位於上游側之端子板731及電極部739周圍之截面圖。第11(b)圖係位於下游側之端子板732及電極部739周圍之截面圖。Fig. 11 is a cross-sectional view showing a straight tube portion 701 to which terminal plates 731 and 732 are attached. Fig. 11(a) is a cross-sectional view showing the vicinity of the terminal plate 731 and the electrode portion 739 on the upstream side. Fig. 11(b) is a cross-sectional view of the terminal plate 732 and the electrode portion 739 located on the downstream side.

橫切直管部701之平坦內面772而突出於直管部701內部之電極部739與包覆於直管部701內之洗滌液接觸。透過電線733，對端子板731、732施加高頻交流電壓，並測定存在於一對電極部739之間之洗滌液的導電度(阻抗)。The electrode portion 739 that protrudes from the flat inner surface 772 of the straight tube portion 701 and protrudes inside the straight tube portion 701 is in contact with the washing liquid that is coated in the straight tube portion 701. A high-frequency AC voltage is applied to the terminal plates 731 and 732 through the electric wires 733, and the conductivity (impedance) of the washing liquid existing between the pair of electrode portions 739 is measured.

第12圖係模式地顯示電極部739周圍之洗滌液之液流者。再者，第12圖中，對上游之電極部附上標號739a，對下游之電極部附上標號739b。Fig. 12 schematically shows the flow of the washing liquid around the electrode portion 739. Further, in Fig. 12, the upstream electrode portion is given the reference numeral 739a, and the downstream electrode portion is attached with the reference numeral 739b.

如第12圖所示，一對電極部739a、739b係沿著直管部701之長向方向並列配置。由一對電極部739a、739b之軸所定義之平面P係對直管部701之軸大略平行。上游之電極部739a係將沿著直管部701之軸流動之洗滌液分流為上下方向。因此，橫切平面P之洗滌液的流量會變少。其結果是，適合用於測定洗滌液之導電度之電極部739a、739b之間的空間(例如，15mm以上30mm以下之空間)中，洗滌液之流動性降低。而且，得到適合導電度之測定之洗滌液的流動。As shown in Fig. 12, the pair of electrode portions 739a and 739b are arranged side by side in the longitudinal direction of the straight tube portion 701. The plane P defined by the axes of the pair of electrode portions 739a, 739b is substantially parallel to the axis of the straight tube portion 701. The upstream electrode portion 739a divides the washing liquid flowing along the axis of the straight pipe portion 701 into the vertical direction. Therefore, the flow rate of the washing liquid across the plane P becomes small. As a result, in the space between the electrode portions 739a and 739b for measuring the conductivity of the washing liquid (for example, a space of 15 mm or more and 30 mm or less), the fluidity of the washing liquid is lowered. Moreover, the flow of the washing liquid suitable for the measurement of the conductivity is obtained.

又，如第12圖所示，包含一對電極部739a、739b之軸的平面P係呈水平面。一對電極部739a、739b並且宜為不橫切直管部701之內部空間上部(排水控制單元7在設計上可能發生存留空氣之空間(例如，直管部701之內部空間中上側1/5之區域))及直管部701之內部空間下部(排水控制單元7在設計上可能堆積髒汙成分之空間(例如，直管部701之內部空間中下側1/5之區域))。其結果是，電極部739a、739b之突出部份之面全體接觸於直管部701內之洗滌液。因此，可抑制對於測定直管部701內之空氣之導電度的影響。又，電極部739a、739b在直管部701之內部空間中上側4/5之區域突出時，可抑制對於在直管部701內堆積之髒汙成分之導電度之測定的影響。Further, as shown in Fig. 12, the plane P including the axes of the pair of electrode portions 739a and 739b is a horizontal plane. The pair of electrode portions 739a, 739b are preferably not to cross the upper portion of the inner space of the straight pipe portion 701 (the drainage control unit 7 may be designed to have a space for air to remain (for example, the upper side of the inner space of the straight pipe portion 701 is 1/5). The area)) and the lower portion of the inner space of the straight pipe portion 701 (the drainage control unit 7 is designed to have a space in which the dirt component is accumulated (for example, a region of the lower side of the inner space of the straight pipe portion 701 of 1/5)). As a result, the entire surface of the protruding portions of the electrode portions 739a and 739b is in contact with the washing liquid in the straight tube portion 701. Therefore, the influence on the measurement of the conductivity of the air in the straight tube portion 701 can be suppressed. Further, when the electrode portions 739a and 739b protrude in the region of the upper side 4/5 of the internal space of the straight tube portion 701, the influence on the measurement of the conductivity of the dirt component deposited in the straight tube portion 701 can be suppressed.

第13圖係模式地顯示光感測器72及電極感測器73周圍之洗滌液之流動。第13圖中顯示第7圖至第9圖中相關說明之光感測器72之發光元件721與受光元件722之間之紅外光線之光路250。又，與第12圖同樣，對於配置於上游側之電極部附上標號739a，對於配置於下游側之電極部附上標號739b。Fig. 13 schematically shows the flow of the washing liquid around the photo sensor 72 and the electrode sensor 73. Fig. 13 shows the optical path 250 of the infrared ray between the light-emitting element 721 and the light-receiving element 722 of the photosensor 72 described in the seventh to ninth embodiments. Further, similarly to Fig. 12, reference numeral 739a is attached to the electrode portion disposed on the upstream side, and reference numeral 739b is attached to the electrode portion disposed on the downstream side.

為了防止形成光路250之紅外光線之不必要的折射，形成於直管部701之內壁面之平坦內面772之上游側端部277係由其他之內壁面***。因此，上游側端部277會擾亂洗滌液之液流。因此，為了調整洗滌液之液流直到到達光路250為止，上游側端部277宜形成於相對於光路250相當遠離上游側之位置。此時，橫切光路250之洗滌液成為適合根據到達第7圖至第9圖相關說明之光感測器72之受光元件722之紅外光線之光量而判定之洗滌液濁度之測定的液流。光感測器72之紅外光線不會對洗滌液之流動造成任何影響。因此，業經整流之洗滌液之液流會到達電極部739a、739b。In order to prevent unnecessary refraction of the infrared ray forming the optical path 250, the upstream end portion 277 formed on the flat inner surface 772 of the inner wall surface of the straight tube portion 701 is embossed by the other inner wall surface. Therefore, the upstream side end portion 277 disturbs the flow of the washing liquid. Therefore, in order to adjust the flow of the washing liquid until reaching the optical path 250, the upstream end portion 277 is preferably formed at a position relatively far from the upstream side with respect to the optical path 250. At this time, the washing liquid that crosses the optical path 250 becomes a liquid flow suitable for measuring the turbidity of the washing liquid determined based on the amount of infrared light reaching the light receiving element 722 of the photo sensor 72 of the seventh to ninth drawings. . The infrared light of the photo sensor 72 does not have any effect on the flow of the washing liquid. Therefore, the flow of the rectified washing liquid reaches the electrode portions 739a, 739b.

如第12圖之相關說明，藉由上游之電極部739a，平行於直管部701之軸方向之液流的一部份會朝上下分流。其結果是，洗滌液之液流會被擾亂。電極部739a造成之洗滌液之液流的擾亂由於係在比第7圖至第9圖相關說明之光感測器72更靠近下游側發生，因此幾乎不會對光感測器72進行之濁度測定造成影響。As explained in Fig. 12, a part of the liquid flow parallel to the axial direction of the straight pipe portion 701 is branched upward and downward by the upstream electrode portion 739a. As a result, the flow of the washing liquid is disturbed. The disturbance of the liquid flow of the washing liquid caused by the electrode portion 739a is caused to occur closer to the downstream side than the photo sensor 72 described in connection with Figs. 7 to 9, so that the photo sensor 72 is hardly turbid. The degree of measurement has an impact.

如第12圖之相關說明，由電極部739a、739b之軸所定義之平面P係對直管部701之軸大略平行。因此，例如，若在直管部701內使洗滌液為逆流(由直管部701朝水槽31之排出口311(參照第1圖)之方向)，電極部739b會使洗滌液之液流朝上下分流，但電極部739a在洗滌液之液流方向中，會與電極部739b重疊，因此不會過度擾亂洗滌液之液流。因此，即使係使洗滌液逆流之情況，亦可以較高精度感測通過光路250之洗滌液的濁度。As described in connection with Fig. 12, the plane P defined by the axes of the electrode portions 739a, 739b is substantially parallel to the axis of the straight tube portion 701. Therefore, for example, when the washing liquid is reversely flowed in the straight pipe portion 701 (the straight pipe portion 701 faces the discharge port 311 of the water tank 31 (see FIG. 1)), the electrode portion 739b causes the washing liquid to flow toward the inside. The upper and lower sides are branched, but the electrode portion 739a overlaps with the electrode portion 739b in the liquid flow direction of the washing liquid, so that the liquid flow of the washing liquid is not excessively disturbed. Therefore, even if the washing liquid is caused to flow backward, the turbidity of the washing liquid passing through the optical path 250 can be sensed with high precision.

在劃定平坦內面772之上側之界線的上緣391及劃定平坦內面772之下側之界線的下緣392中，直管部701係成屈曲成凹狀之截面輪廓形狀(參照第7圖)。在構成該屈曲之截面輪廓形狀之部份中，洗滌液之液流比其他部份容易滯留。如第13圖所示，電極部739a、739b配設成：電極部739a、739b之截面之一部份會進入平坦內面772。在由電極部739a、739b所挾持之上緣391附近，由於洗滌液特別容易滯留，因此可得到適合測定洗滌液導電性之低流動性的液流。又，藉由在電極部739a、739b之間所劃定出之平面P與上緣391大略平行，藉此可更為提高導電度之測定精度。In the lower edge 392 which defines the boundary between the upper boundary of the upper side of the flat inner surface 772 and the lower boundary of the flat inner surface 772, the straight tube portion 701 is bent into a concave cross-sectional contour shape (refer to 7)). In the portion constituting the cross-sectional contour shape of the buckling, the liquid flow of the washing liquid is liable to be retained more than other portions. As shown in Fig. 13, the electrode portions 739a, 739b are disposed such that a portion of the cross section of the electrode portions 739a, 739b enters the flat inner surface 772. In the vicinity of the upper edge 391 held by the electrode portions 739a and 739b, the washing liquid is particularly liable to stay, so that a liquid flow suitable for measuring the low fluidity of the conductivity of the washing liquid can be obtained. Further, since the plane P defined between the electrode portions 739a and 739b is substantially parallel to the upper edge 391, the measurement accuracy of the conductivity can be further improved.

再次參照第1圖至第5圖。電極感測器73之下游配設有循環泵71。循環泵71與排水控制單元7之筐體70之間配設有吸引管路711，吸引管路711包含：與循環泵71之吸引口連接之一端部、及連接於在排水控制單元7之筐體70形成之第2開口部771之他端部。由循環泵71之吐出口延伸之第2管路52連接於在水槽31形成之流入口312。Referring again to Figures 1 through 5. A circulation pump 71 is disposed downstream of the electrode sensor 73. A suction line 711 is disposed between the circulation pump 71 and the casing 70 of the drainage control unit 7, and the suction line 711 includes one end connected to the suction port of the circulation pump 71 and a basket connected to the drainage control unit 7. The body 70 is formed at the other end of the second opening portion 771. The second line 52 extending from the discharge port of the circulation pump 71 is connected to the inlet 312 formed in the water tank 31.

第14圖係模式地顯示由電極感測器73到循環泵71之洗滌液之液流的平面圖。與第14圖一併參照第1圖及第2圖。第14圖中係顯示吸引管路711。如第14圖所示，電極感測器73係配設於比吸引管路711與排水控制單元7之連接部771(第2圖中顯示為第2開口部771)更靠近上游側。又，與第12圖同樣，對配置於上游側之電極部附上標號739a，對配置於下游側之電極部附上標號739b。Fig. 14 is a plan view schematically showing the flow of the washing liquid from the electrode sensor 73 to the circulation pump 71. Refer to Fig. 1 and Fig. 2 together with Fig. 14. The suction line 711 is shown in Fig. 14. As shown in Fig. 14, the electrode sensor 73 is disposed closer to the upstream side than the connection portion 771 (the second opening portion 771 shown in Fig. 2) of the suction line 711 and the drainage control unit 7. Further, similarly to Fig. 12, reference numeral 739a is attached to the electrode portion disposed on the upstream side, and reference numeral 739b is attached to the electrode portion disposed on the downstream side.

構成排水控制單元7之筐體70之直管部701及收容管部702在平面視圖中係形成筆直的流路(第14圖中，直管部701與收容管部702之界線使用虛線表示)。吸引管路711連接於直管部701及收容管部702形成之筆直流路。吸引管路711朝與直管部701及收容管部702形成之筆直流路之延伸方向不同之方向(第14圖所示之排水控制單元7之構造中為直角方向)延伸。沿著筆直流路而流動之洗滌液受到來自循環泵71之吸引力而改變流動方向，成為朝吸引管路711流動。電極感測器73係由與連接部771相對向之側之直管部701的內面突出。再者，所謂「與連接部771對向之側的內面」，係指沿著直管部701及收容管部702之長向方向軸，將直管部701及收容管部702分隔時，存在於距離連接部771較遠之位置者之內面，且為以吸引管路711之軸為基點，例如，位於上游及/或下游，相差吸引管路711之內徑之3倍至4倍之長度之收容管部702及/或直管部701之內面區域。較佳的是意指以吸引管路711之軸為基點，位於上游及/或下游相差吸引管路711之內徑之3.5倍長度之收容管部702及/或直管部之內面區域，更佳的是意指以吸引管路711之軸為基點，位於上游及/或下游相差吸引管路711之內徑之3倍長度之收容管部702及/或直管部701之內面區域。電極感測器73之電極部739a、739b係由此等內面區域突出。The straight pipe portion 701 and the accommodating pipe portion 702 constituting the casing 70 of the drainage control unit 7 form a straight flow path in plan view (in FIG. 14, the boundary between the straight pipe portion 701 and the accommodating pipe portion 702 is indicated by a broken line) . The suction line 711 is connected to the straight tube portion 701 and the pen DC path formed by the housing tube portion 702. The suction line 711 extends in a direction different from the direction in which the straight line portion 701 and the accommodating tube portion 702 extend in the direction in which the pen-shaped DC path extends (the direction of the drainage control unit 7 shown in FIG. 14 is a right-angle direction). The washing liquid flowing along the pen DC path is subjected to the suction force from the circulation pump 71 to change the flow direction, and flows toward the suction line 711. The electrode sensor 73 protrudes from the inner surface of the straight tube portion 701 on the side opposite to the connection portion 771. In addition, the "inner surface on the side opposite to the connecting portion 771" means that the straight tube portion 701 and the housing tube portion 702 are separated along the longitudinal direction axis of the straight tube portion 701 and the housing tube portion 702. It exists on the inner surface of the position far from the connecting portion 771, and is based on the axis of the suction pipe 711, for example, located upstream and/or downstream, 3 to 4 times the inner diameter of the phase difference suction pipe 711 The length of the receiving tube portion 702 and/or the inner surface region of the straight tube portion 701. Preferably, the inner side of the receiving tube portion 702 and/or the straight tube portion having a length of 3.5 times the inner diameter of the upstream and/or downstream phase difference suction line 711 is taken as the base point of the suction line 711. More preferably, it means that the inner side of the housing tube portion 702 and/or the straight tube portion 701 which is three times the inner diameter of the upstream and/or downstream phase difference suction line 711 is based on the axis of the suction line 711. . The electrode portions 739a, 739b of the electrode sensor 73 protrude from the inner surface region.

第14圖係顯示橫切電極感測器73附近之管路之截面C上之任意點P1。點P1係離開連接部771之位置(即，與連接部771相對向之面附近)之任意點。點P1中，由電極部739a、739b之基端部朝向前端部之方向之洗滌液之流力V1會產生作用。因此，藉由電極感測器73配設於與連接部771相對向之位置，可促進除去卡在電極感測器73之棉纖維。Fig. 14 shows an arbitrary point P1 on the section C of the pipe near the electrode sensor 73. The point P1 is an arbitrary point away from the position of the connecting portion 771 (i.e., in the vicinity of the surface opposite to the connecting portion 771). In the point P1, the flow force V1 of the washing liquid in the direction from the base end portion of the electrode portions 739a and 739b toward the tip end portion acts. Therefore, by disposing the electrode sensor 73 at a position opposed to the connecting portion 771, it is possible to facilitate the removal of the cotton fibers stuck in the electrode sensor 73.

如上所述，電極部739a、739b係在直管部701內形成突出部。因此，流入至控制單元7之洗滌液所含之棉纖維容易卡在電極部739a、739b。然而，藉由流力V1，卡在電極部739a、739b之棉纖維會變得比較容易由電極部739a、739b除去。再者，如第2圖所示，收容於收容管部702之過濾部76(參照第1圖)之一部份存在於電極感測器73與連接部771之間。第14圖中，在網狀區域中概略地表示過濾部76。洗滌液通過存在於過濾部76之上游位置之電極感測器73後，且在到達存在於過濾部76之下游位置之吸引管路711之前，會通過配設於收容管部702內之過濾部76。因此，棉纖維由電極部739a、739b除去後，會由過濾部76收集。又，過濾部76具有可與洗滌液之流動抵抗之機能，因此在循環泵71停止後，可使電極部周圍之洗滌液之流動急速降低。As described above, the electrode portions 739a and 739b form a protruding portion in the straight tube portion 701. Therefore, the cotton fibers contained in the washing liquid flowing into the control unit 7 are easily caught on the electrode portions 739a and 739b. However, by the flow force V1, the cotton fibers stuck on the electrode portions 739a, 739b are relatively easily removed by the electrode portions 739a, 739b. Further, as shown in FIG. 2, a portion of the filter portion 76 (see FIG. 1) accommodated in the housing tube portion 702 exists between the electrode sensor 73 and the connection portion 771. In Fig. 14, the filter portion 76 is schematically shown in the mesh region. The washing liquid passes through the electrode sensor 73 existing at the upstream position of the filter portion 76, and passes through the filter portion disposed in the housing tube portion 702 before reaching the suction line 711 existing at a position downstream of the filter portion 76. 76. Therefore, the cotton fibers are collected by the filter portion 76 after being removed by the electrode portions 739a and 739b. Further, since the filter unit 76 has a function of resisting the flow of the washing liquid, the flow of the washing liquid around the electrode portion can be rapidly lowered after the circulation pump 71 is stopped.

第15圖係用以說明使用了循環泵71及排水閥75除去棉纖維者。第15(a)圖係模式地顯示由電極感測器73到循環泵71之洗滌液之液流的平面圖。第15(b)圖係模式地顯示由電極感測器73到排水閥75洗滌液之液流之平面圖。與第15圖一併參照第1圖。再者，第15圖係顯示形成到循環泵71之流路之吸引管路711及形成到排水閥75之流路之排水管路74。又，與第12圖同樣，對上游之電極部附上標號739a，對下游之電極部附上標號739b。再者，第15(a)圖與第14圖所示之模式圖同樣，係用以顯示第15(b)圖所示之洗滌液之流動形態之對比。Fig. 15 is a view for explaining the use of the circulation pump 71 and the drain valve 75 to remove cotton fibers. Fig. 15(a) is a plan view schematically showing the flow of the washing liquid from the electrode sensor 73 to the circulation pump 71. The 15th (b)th diagram schematically shows a plan view of the flow of the washing liquid from the electrode sensor 73 to the drain valve 75. Refer to Fig. 1 together with Fig. 15. Further, Fig. 15 shows a suction line 711 which forms a flow path to the circulation pump 71 and a drain line 74 which forms a flow path to the drain valve 75. Further, similarly to Fig. 12, the upstream electrode portion is given the reference numeral 739a, and the downstream electrode portion is attached with the reference numeral 739b. Further, the 15th (a) diagram is the same as the pattern diagram shown in Fig. 14 for displaying the comparison of the flow patterns of the washing liquid shown in Fig. 15(b).

如第15(a)圖所示，電極感測器73宜係相對於排水管路74之連接部774(第1開口部774)配設於下游，且相對於吸引管路711之連接部771(第2開口部771)配設於上游。藉由如此之電極感測器73之配置，在電極部739a、739b突出之管路部份中，當開啟排水閥75時，則如第15(b)圖所示，會產生與循環泵71作動時逆向之洗滌液之液流。而且，卡在電極部739a、739b之棉纖維會變得容易由電極部739a、739b除去。As shown in Fig. 15(a), the electrode sensor 73 is preferably disposed downstream of the connection portion 774 (first opening portion 774) of the drain line 74, and is connected to the connection portion 771 of the suction line 711. The (second opening portion 771) is disposed upstream. With such a configuration of the electrode sensor 73, in the portion of the pipe in which the electrode portions 739a, 739b protrude, when the drain valve 75 is opened, as shown in Fig. 15(b), the circulation pump 71 is generated. The flow of the washing liquid in the reverse direction at the time of actuation. Further, the cotton fibers stuck in the electrode portions 739a and 739b are easily removed by the electrode portions 739a and 739b.

Figure 16(b) is a plan view of the circulation pump 71. Fig. 16(C) is a view of the circulation pump 71 viewed from the suction port side.

循環泵71包含形成循環泵71之外壁之泵殼713。泵殼713內部配置有軸承隔壁714。軸承隔壁714將泵殼713之內部空間劃分成2個空間。連通到吸引口715之空間內，配設有渦輪717。與配設有渦輪717之空間鄰接之空間內配設有馬達718。馬達718適合使用例如直流電無刷馬達。馬達718之旋轉軸719橫切軸承隔壁714並朝配設有渦輪717之空間延伸。業已與軸承隔壁714一體化之渦輪717係由旋轉軸719所支持。藉由馬達718之驅動，渦輪717與軸承隔壁714一起旋轉。The circulation pump 71 includes a pump casing 713 that forms an outer wall of the circulation pump 71. A bearing partition 714 is disposed inside the pump casing 713. The bearing partition 714 divides the internal space of the pump casing 713 into two spaces. A turbine 717 is disposed in a space that communicates with the suction port 715. A motor 718 is disposed in a space adjacent to the space in which the turbine 717 is disposed. Motor 718 is suitable for use, for example, with a DC brushless motor. The rotating shaft 719 of the motor 718 crosses the bearing partition 714 and extends toward the space in which the turbine 717 is disposed. The turbine 717 that has been integrated with the bearing partition 714 is supported by the rotating shaft 719. The turbine 717 rotates with the bearing partition 714 by the drive of the motor 718.

泵殼713形成有與吸引管路711連接之吸引口715、及與第2管路52連接之吐出口716。吸引口715及吐出口716係連通到配設有渦輪717之空間。The pump casing 713 is formed with a suction port 715 connected to the suction pipe 711 and a discharge port 716 connected to the second pipe 52. The suction port 715 and the discharge port 716 are connected to a space in which the turbine 717 is disposed.

安裝座131自泵殼713之外面朝半徑方向突出。如第16圖所示之循環泵71之安裝座131包含朝外方大幅突出之3個C型安裝片132。安裝片132係使用螺栓固定於底座712(參照第1圖)之突座部。The mount 131 protrudes from the outer surface of the pump casing 713 in the radial direction. The mount 131 of the circulation pump 71 shown in Fig. 16 includes three C-shaped mounting pieces 132 that protrude largely toward the outside. The mounting piece 132 is fixed to the protruding portion of the base 712 (see FIG. 1) by bolts.

第17圖係顯示水槽31與第2管路52之連接部的構造。第17(a)圖係構成連接部之導管的平面圖。第17(b)圖係第17(a)圖所示之導管的橫截面圖。第17(C)圖係第17(a)圖所示之導管的縱截面圖。Fig. 17 shows the structure of the connection portion between the water tank 31 and the second duct 52. Fig. 17(a) is a plan view showing a duct constituting the connecting portion. Figure 17(b) is a cross-sectional view of the catheter shown in Figure 17(a). Fig. 17(C) is a longitudinal sectional view of the catheter shown in Fig. 17(a).

水槽31之流入口312係由自水槽31之外壁朝上方突出之環狀肋121所形成。沿著環狀肋121之內周面配設有O環122。O環122被導管槽溝520推壓。The inlet 312 of the water tank 31 is formed by an annular rib 121 that protrudes upward from the outer wall of the water tank 31. An O-ring 122 is disposed along the inner circumferential surface of the annular rib 121. The O-ring 122 is pushed by the conduit groove 520.

導管槽溝520具有屈曲成L字狀之本體部521。本體部521包含：與第2管路52連接之導管522、與由導管522朝流入口312延伸之下半管路523。下半管路523之前端部具有：構成與流入口312之開口部互補之外周輪廓之環狀突出部525。環狀突出部525之內部配設有擠壓壁123。擠壓壁123係由環狀突出部525之內部空間之大略中心位置朝下方彎曲成弧狀，且具有朝向旋轉滾筒32之旋轉中心方向之截面。擠壓壁123之兩端連接於環狀突出部525之內壁面。環狀突出部525與環狀肋121之間配設有O環122。O環122係在環狀突出部525與環狀肋121之間被壓縮，且作為密封構件之機能。The duct groove 520 has a body portion 521 that is bent in an L shape. The main body portion 521 includes a duct 522 connected to the second duct 52 and a lower duct 523 extending from the duct 522 toward the inflow port 312. The front end portion of the lower half pipe 523 has an annular projecting portion 525 constituting an outer peripheral contour complementary to the opening portion of the inflow port 312. The inside of the annular projection 525 is provided with a pressing wall 123. The pressing wall 123 is curved downward in a curved shape from a substantially central position of the inner space of the annular projection 525, and has a cross section toward the center of rotation of the rotary drum 32. Both ends of the pressing wall 123 are connected to the inner wall surface of the annular projection 525. An O-ring 122 is disposed between the annular protruding portion 525 and the annular rib 121. The O-ring 122 is compressed between the annular projecting portion 525 and the annular rib 121, and functions as a sealing member.

導管槽溝520之下半管路523與環狀肋121鄰接，且使用固定具125(第17圖中，突座係以固定具125表示)固定於形成於水槽31之壁部之較厚部124。The lower half pipe 523 of the duct groove 520 is adjacent to the annular rib 121, and is fixed to the thick portion formed on the wall portion of the water tank 31 by using the fixture 125 (in FIG. 17, the pedestal is represented by the fixture 125). 124.

導管槽溝520進而包含蓋524。蓋524與下半管路523一倂由導管522所形成之流路屈曲，而形成朝向流入口312之流路。藉由循環泵71之作動，由第2管路52通過導管槽溝520，洗滌液流入到流入口312。再者，循環泵71係以例如3500rpm之旋轉數旋轉。The conduit groove 520 further includes a cover 524. The cover 524 and the lower half of the line 523 are flexed by the flow path formed by the duct 522 to form a flow path toward the inflow port 312. By the operation of the circulation pump 71, the second line 52 passes through the duct groove 520, and the washing liquid flows into the inflow port 312. Further, the circulation pump 71 is rotated at, for example, a rotation number of 3,500 rpm.

水槽31之內部配設有旋轉滾筒32。旋轉滾筒32之上面與流入口312之間配設有承擋壁126。承擋壁126係由與水槽31之外壁連接之連接壁127所支持。承擋壁126與擠壓壁123形成狹小流路。該狹小流路係作為使洗滌液噴射到洗滌槽3內之噴射口129的機能。A rotating drum 32 is disposed inside the water tank 31. A bearing wall 126 is disposed between the upper surface of the rotating drum 32 and the inflow port 312. The retaining wall 126 is supported by a connecting wall 127 that is coupled to the outer wall of the sink 31. The retaining wall 126 forms a narrow flow path with the extruded wall 123. This narrow flow path functions as an ejection port 129 for injecting the washing liquid into the washing tub 3.

通過承擋壁126與擠壓壁123所形成之噴射口129之洗滌液接著通過形成於構成水槽31之外面之一部份之前端壁128與旋轉滾筒32之前端壁321之間之流路281，並供給到旋轉滾筒32之內部。前端壁128與擠壓壁123共同動作而推壓O環122。The washing liquid passing through the injection port 129 formed by the retaining wall 126 and the pressing wall 123 is then passed through a flow path 281 formed between the end wall 128 of the outer surface constituting the outer surface of the water tank 31 and the front end wall 321 of the rotary drum 32. And supplied to the inside of the rotary drum 32. The front end wall 128 cooperates with the pressing wall 123 to push the O-ring 122.

噴射口129與旋轉滾筒32係分開形成。旋轉滾筒32內之洗滌物不接觸到噴射口129。因此，噴射口129幾乎不會對洗滌步驟、沖洗步驟或乾燥步驟造成不良影響。噴射口129不會傷害洗滌物、使之破損，也幾乎不會損害洗滌物之外觀。進而，噴射口129之下游之流路281係由水槽31之前端壁128與旋轉滾筒32之前端壁321所形成，因此不需要用以防止漏水之追加構造。第17圖所示之構造中，僅使用O環122作為密封構件。The injection port 129 is formed separately from the rotary drum 32. The laundry in the rotary drum 32 does not contact the ejection opening 129. Therefore, the ejection port 129 hardly adversely affects the washing step, the rinsing step or the drying step. The ejection opening 129 does not damage the laundry, breaks it, and hardly impairs the appearance of the laundry. Further, since the flow path 281 downstream of the injection port 129 is formed by the front end wall 128 of the water tank 31 and the front end wall 321 of the rotary drum 32, an additional structure for preventing water leakage is not required. In the configuration shown in Fig. 17, only the O-ring 122 is used as the sealing member.

水槽31之前端壁128及旋轉滾筒32之前端壁321形成環狀出口部282。通過流路281之洗滌液通過環狀之出口部282，並且朝旋轉滾筒32之旋轉中心軸噴射。通過出口部282噴射之洗滌液可有效率地噴射到旋轉滾筒32之內側旋轉區域。而且，與收容到旋轉滾筒32內之洗滌物的量無關，洗滌液可有效率地供給到洗滌物。The front end wall 128 of the water tank 31 and the front end wall 321 of the rotary drum 32 form an annular outlet portion 282. The washing liquid passing through the flow path 281 passes through the annular outlet portion 282 and is ejected toward the central axis of rotation of the rotary drum 32. The washing liquid sprayed through the outlet portion 282 can be efficiently injected to the inner rotation region of the rotary drum 32. Moreover, the washing liquid can be efficiently supplied to the laundry irrespective of the amount of the laundry accommodated in the rotary drum 32.

水槽31之前端壁128之內面(形成流路281之面)包含傾斜面283與彎曲面284。使流路281之截面積朝下游漸漸減少之傾斜面283使通過流路281之洗滌液之流速漸漸增加。因此，通過流路281之洗滌液會一邊加速一變朝向彎曲面284。彎曲面284係使洗滌液之液流方向朝旋轉滾筒32之底部之方向產生變化。因此，由出口部282噴射之洗滌液會朝向旋轉滾筒32之底部。其結果是，洗滌液可有效率地供給到洗滌物。The inner surface of the front end wall 128 of the water tank 31 (the surface on which the flow path 281 is formed) includes an inclined surface 283 and a curved surface 284. The inclined surface 283 which gradually reduces the cross-sectional area of the flow path 281 toward the downstream gradually increases the flow rate of the washing liquid passing through the flow path 281. Therefore, the washing liquid passing through the flow path 281 is accelerated toward the curved surface 284. The curved surface 284 changes the direction of the flow of the washing liquid toward the bottom of the rotating drum 32. Therefore, the washing liquid sprayed by the outlet portion 282 is directed toward the bottom of the rotary drum 32. As a result, the washing liquid can be efficiently supplied to the laundry.

噴射口129之開口涵括洗滌槽3之周方向之預定範圍。連接壁127及承擋壁126係使噴射口129朝旋轉中心軸方向開口。連接壁127及承擋壁126幾乎不會擾亂流入到流入口312之洗滌液，且導引到流路281。洗滌液朝周方向擴散到噴射口129，然後安定的流入流路281。然後，洗滌液進一步朝周方向擴散並流動到環狀出口部282。因此，洗滌液會由出口部282全體噴射，與收容到旋轉滾筒32內之洗滌物的量無關，而可安定的供給到洗滌物。The opening of the injection port 129 covers a predetermined range of the circumferential direction of the washing tub 3. The connecting wall 127 and the receiving wall 126 open the injection port 129 in the direction of the central axis of rotation. The connecting wall 127 and the receiving wall 126 hardly disturb the washing liquid flowing into the inflow port 312 and are guided to the flow path 281. The washing liquid is diffused in the circumferential direction to the injection port 129, and then settles into the flow path 281. Then, the washing liquid is further diffused in the circumferential direction and flows to the annular outlet portion 282. Therefore, the washing liquid is ejected from the entire outlet portion 282, and can be stably supplied to the laundry regardless of the amount of the laundry accommodated in the rotary drum 32.

導管槽溝520之蓋524係使用簡單的安裝構造而形成朝向流入口312之流路。適當地制定覆蓋流入口312之蓋524的形狀以及尺寸、連接壁127之形狀以及尺寸、及承擋壁126之形狀以及尺寸，藉此可得到適切的洗滌液往旋轉滾筒32內流入。藉由適當地制定蓋524、連接壁127及承擋壁126之設計參數，可適切地決定由噴射口129噴射之洗滌液之流寬、流厚及流速。而且，與收容到旋轉滾筒32內之洗滌物的量無關，洗滌液可有效率地供給到洗滌物。The cover 524 of the conduit groove 520 forms a flow path toward the inflow port 312 using a simple mounting configuration. The shape and size of the cover 524 covering the inflow port 312, the shape and size of the connecting wall 127, and the shape and size of the retaining wall 126 are appropriately set, whereby an appropriate washing liquid can be supplied into the rotating drum 32. By appropriately setting the design parameters of the cover 524, the connecting wall 127, and the retaining wall 126, the flow width, flow thickness, and flow rate of the washing liquid sprayed by the injection port 129 can be appropriately determined. Moreover, the washing liquid can be efficiently supplied to the laundry irrespective of the amount of the laundry accommodated in the rotary drum 32.

第17圖所示之導管槽溝520之蓋524之安裝構造或連接壁127及承擋壁126之非常簡單的構造對於抑制漏水以及製造成本之低廉化也有所貢獻。The mounting structure of the cover 524 of the duct groove 520 shown in Fig. 17, or the very simple structure of the connecting wall 127 and the retaining wall 126 contributes to the suppression of water leakage and the reduction in manufacturing cost.

如上所述，導管槽溝520係在下半管路523與蓋524形成朝向流入口312之流路。如第1圖所示，導管槽溝520形成之流路係沿著水槽31之外面延伸。因此，使用下半管路523與蓋524，在水槽31與筐體2之間之小空隙形成具有矩形截面之平坦管路。平坦管路係用以規定適合噴射口129之形狀、大小之流寬以及流厚之洗滌液之液流。通過平坦管路之洗滌液會被整流而朝向噴射口129。As described above, the duct groove 520 forms a flow path toward the inflow port 312 in the lower half line 523 and the cover 524. As shown in Fig. 1, the flow path formed by the duct groove 520 extends along the outer surface of the water tank 31. Therefore, the lower half pipe 523 and the cover 524 are used, and a small gap between the water tank 31 and the casing 2 forms a flat pipe having a rectangular cross section. The flat line is used to define a flow of the washing liquid suitable for the shape, size, and thickness of the injection port 129. The washing liquid passing through the flat line is rectified toward the injection port 129.

旋轉滾筒32之前端壁321上形成複數之突條322。突條322係朝旋轉滾筒32之前端壁321之周方向在預定長度之範圍內延伸。複數之突條322之周方向的位置及/或半徑方向之位置亦可互為不同。突條322可將噴射口129之下游之流路281之截面積局部縮小。在出口部282附近利用突條322縮小流路截面積之情況，與在離開出口部282之處利用突條322縮小流路截面積之情況中，由出口部282噴出之洗滌液之移動軌跡不同。因此，由出口部282排出之洗滌液會振散到旋轉滾筒32內之廣大範圍，達成以較高效率將洗滌液供給到洗滌物。A plurality of ridges 322 are formed on the front end wall 321 of the rotating drum 32. The ridge 322 extends in a circumferential direction of the front end wall 321 of the rotary drum 32 within a predetermined length. The position of the plurality of protrusions 322 in the circumferential direction and/or the position in the radial direction may be different from each other. The rib 322 can partially reduce the cross-sectional area of the flow path 281 downstream of the injection port 129. In the vicinity of the outlet portion 282, the cross-sectional area of the flow path is narrowed by the ridge 322, and in the case where the cross-sectional area of the flow path is narrowed by the ridge 322 at the exit portion 282, the movement trajectory of the washing liquid ejected from the outlet portion 282 is different. . Therefore, the washing liquid discharged from the outlet portion 282 is oscillated to a wide range in the rotary drum 32, and the washing liquid is supplied to the laundry with higher efficiency.

突條322之形狀並不限定於第17圖所示者。例如，突條322亦可為波型形狀，亦可為葉片型形狀。亦可採用可使由出口部282排出之洗滌液之移動軌跡變動之任意形狀的突條322。又，亦可採用可使由出口部282排出之洗滌液之移動軌跡變動之任意形狀之突條322的配置。The shape of the ridge 322 is not limited to that shown in Fig. 17. For example, the ridge 322 may have a wave shape or a blade shape. A rib 322 of any shape that can change the movement trajectory of the washing liquid discharged from the outlet portion 282 can also be used. Further, it is also possible to arrange the protrusions 322 of any shape that can change the movement trajectory of the washing liquid discharged from the outlet portion 282.

承擋壁126與旋轉滾筒32之間形成空隙266。當循環泵71以低速運轉時(例如，1000rpm)，洗滌液會由噴射口129流入到空隙266。流入到空隙266之洗滌液會在旋轉滾筒32與水槽31之間的空間傳送朝向水槽31之排出口311。A gap 266 is formed between the bearing wall 126 and the rotating drum 32. When the circulation pump 71 is operated at a low speed (for example, 1000 rpm), the washing liquid flows into the gap 266 from the injection port 129. The washing liquid flowing into the gap 266 is conveyed toward the discharge port 311 of the water tank 31 in the space between the rotary drum 32 and the water tank 31.

第18圖係例示控制電路部81之機能構成。Fig. 18 is a diagram showing the functional configuration of the control circuit unit 81.

控制電路部81包含：演算部813、判定部814及記憶部816。例如，使用者操作操作面板8時，演算部813使用控制電路部81具有之計時器及儲存於記憶部816之程式，算出洗衣機1要執行使用者指定之洗滌模式之各步驟中的哪個步驟。演算部813根據算出之結果，使判定部814判定執行中之步驟中是否預定之動作為必要。再者，演算部813算出之結果亦可暫時地儲存於記憶部816。例如，當演算部813將從沖洗步驟開始時之經過時間相關之資訊輸出到判定部814時，判定部814會判定從沖洗步驟開始時是否已經過預定之時間。若已經過預定之時間，判定部814則將用以開啟排水閥75之控制信號朝排水閥75發送。同樣地，供水系統4之電磁閥或排水系統5之循環泵71根據來自演算部813之信號，在洗滌模式之各步驟中執行預先訂定之動作。The control circuit unit 81 includes an arithmetic unit 813, a determination unit 814, and a storage unit 816. For example, when the user operates the operation panel 8, the calculation unit 813 uses the timer included in the control circuit unit 81 and the program stored in the storage unit 816 to calculate which of the steps of the washing mode to be executed by the washing machine 1 is to be executed. Based on the result of the calculation, the calculation unit 813 causes the determination unit 814 to determine whether or not the predetermined operation in the step being executed is necessary. Furthermore, the result calculated by the calculation unit 813 can be temporarily stored in the storage unit 816. For example, when the calculation unit 813 outputs the information on the elapsed time from the start of the flushing step to the determination unit 814, the determination unit 814 determines whether or not a predetermined time has elapsed since the start of the flushing step. If the predetermined time has elapsed, the determination unit 814 transmits a control signal for opening the drain valve 75 to the drain valve 75. Similarly, the solenoid valve of the water supply system 4 or the circulation pump 71 of the drainage system 5 performs a predetermined operation in each step of the washing mode based on the signal from the calculation unit 813.

判定部814自演算部813接收清洗步驟及/或沖洗步驟之開始時刻、及/或、清洗步驟及/或沖洗步驟之經過時間的資訊，將控制信號發送到循環泵71，使循環泵71在清洗步驟及/或沖洗步驟之預定期間之期間內間歇地運轉。接收到控制信號之循環泵71進行反覆運轉及停止之間歇動作。The determining unit 814 receives the information of the cleaning step and/or the start time of the washing step, and/or the cleaning step and/or the elapsed time of the flushing step from the calculation unit 813, and transmits a control signal to the circulation pump 71 to cause the circulation pump 71 to The cleaning step and/or the rinsing step are intermittently operated during the predetermined period of time. The circulation pump 71 that has received the control signal performs an intermittent operation of the reverse operation and the stop.

第19圖係顯示循環泵71進行間歇動作期間之由光感測器72發送之信號之圖表。第19(a)圖係顯示洗滌液之起泡大時之來自光感測器72的信號。第19(b)圖係顯示當洗滌液之起泡小時之來自光感測器72之信號。第19圖中，左側之縱軸係顯示循環泵71之旋轉數，右側之縱軸係以位元表示來自光感測器72之輸出。再者，圖表中，表示來自光感測器72之輸出之各點為5個樣品之平均值。Fig. 19 is a graph showing signals transmitted by the photo sensor 72 during the intermittent operation of the circulation pump 71. Fig. 19(a) shows the signal from the photo sensor 72 when the foaming of the washing liquid is large. Fig. 19(b) shows the signal from the photo sensor 72 when the washing liquid is foamed for a small amount. In Fig. 19, the vertical axis on the left side shows the number of rotations of the circulation pump 71, and the vertical axis on the right side shows the output from the photo sensor 72 in bits. Further, in the graph, each point representing the output from the photo sensor 72 is an average of five samples.

在說明第19圖所示之資料之前，說明來自光感測器72之輸出變動的原理。洗滌液之濁度低時，光感測器72之受光元件722相較於濁度高時受光較多。因此，當洗滌液之濁度低時，相較於濁度高時，較多的電流會流向受光元件722，電阻之電壓下降。該結果是，光感測器72之輸出會下降。當洗滌液之濁度高時，光感測器72之受光元件722相較於濁度低之情況，受光會較少。因此，當洗滌液之濁度高時，相較於濁度低的情況，較少的電流會流向受光元件722，電阻之電壓上升。該結果是，光感測器72之輸出會上升。Before explaining the information shown in Fig. 19, the principle of the output variation from the photo sensor 72 will be explained. When the turbidity of the washing liquid is low, the light receiving element 722 of the photo sensor 72 receives more light than when the turbidity is high. Therefore, when the turbidity of the washing liquid is low, when the turbidity is high, a large amount of current flows to the light receiving element 722, and the voltage of the electric resistance drops. As a result, the output of the photo sensor 72 will drop. When the turbidity of the washing liquid is high, the light receiving element 722 of the photo sensor 72 receives less light than when the turbidity is low. Therefore, when the turbidity of the washing liquid is high, less current flows to the light receiving element 722 than when the turbidity is low, and the voltage of the electric resistance rises. As a result, the output of the photo sensor 72 will rise.

說明第19圖所示之資料。如第19圖所示，光感測器72之輸出會大略與循環泵71之間歇運動同步而變動。當循環泵71之旋轉數增加時，光感測器72之輸出也會增加。當循環泵71停止時，光感測器72之輸出會降低。由第19(a)圖與第19(b)圖之比較可知，洗滌液之起泡較大時，光感測器72之輸出變化的振幅會變大。洗滌液之泡會使來自光感測器72之發光元件721的紅外光線散射，因此當泡多時，光感測器72之輸出會變小。另一方面，當泡少時，光感測器72之輸出會變大。循環泵71運轉時，藉由水流在直管部701內產生很多泡。該結果是，在直管部701內流動之泡會變得比較多。在直管部701內流動之泡會使光感測器72之光線散射，因此較少的電流會流動於受光元件722。如上所述，當較少電流流動於受光元件722時，由於電阻之電壓會上升，因此光感測器72之輸出會增大。另一方面，當循環泵71停止時，洗滌液之流動會下降，因此直管部701內之泡會浮起到上方。該結果是，使光感測器72之光線散射之泡量變少。因此，較多的電流在受光元件722流動，電阻之電壓降低。而且，光感測器72之輸出降低。如此，洗滌液之起泡程度會與光感測器72之光線的散射量有直接關連，而定義為使光感測器72之光線散射之泡量。Explain the information shown in Figure 19. As shown in Fig. 19, the output of the photo sensor 72 is substantially changed in synchronization with the intermittent motion of the circulation pump 71. As the number of revolutions of the circulation pump 71 increases, the output of the photo sensor 72 also increases. When the circulation pump 71 is stopped, the output of the photo sensor 72 is lowered. From the comparison between Fig. 19(a) and Fig. 19(b), it is understood that when the foaming of the washing liquid is large, the amplitude of the change in the output of the photosensor 72 becomes large. The bubble of the washing liquid scatters the infrared light from the light-emitting element 721 of the photo sensor 72, so that when the bubble is large, the output of the photo sensor 72 becomes small. On the other hand, when the bubble is small, the output of the photo sensor 72 becomes large. When the circulation pump 71 is operated, a lot of bubbles are generated in the straight pipe portion 701 by the water flow. As a result, the bubbles flowing in the straight tube portion 701 become more numerous. The bubble flowing in the straight tube portion 701 causes the light of the photo sensor 72 to scatter, so that less current flows to the light receiving element 722. As described above, when less current flows to the light receiving element 722, since the voltage of the resistor rises, the output of the photo sensor 72 increases. On the other hand, when the circulation pump 71 is stopped, the flow of the washing liquid is lowered, so that the bubble in the straight tube portion 701 floats upward. As a result, the amount of bubbles that scatter the light of the photo sensor 72 becomes small. Therefore, a large amount of current flows in the light receiving element 722, and the voltage of the resistor is lowered. Moreover, the output of the photo sensor 72 is lowered. Thus, the degree of foaming of the washing liquid is directly related to the amount of scattering of the light of the photo sensor 72, and is defined as the amount of bubbles that scatter the light of the photo sensor 72.

第18圖所示之演算部813係演算例如循環泵71在運轉期間之光感測器72的輸出、及循環泵71在停止期間之光感測器72之輸出的差(以下，稱為輸出差)。在此，循環泵71運轉期間與停止期間亦可定義為「一運轉周期」。為了降低光感測器72之輸出所含之雜訊的影響，亦可將在每一運轉周期所算出之輸出差予以平均化。判定部814亦可將例如對於儲存於記憶部816之光感測器72之輸出差的臨界值、與演算部813之演算結果相比較，判定洗滌液之起泡程度。藉由對於業已平均化之輸出差之臨界值的比較，可降低雜訊對於起泡之判定的影響。再者，演算部813進行之演算並非係限定於算出循環泵71運轉期間之光感測器72之輸出與循環泵71停止期間之光感測器72之輸出的差者。取而代之，亦可使用可算出循環泵71之運轉開始時或者剛停止後之光感測器72之輸出的變化率或光感測器72之輸出變動的大小之其他演算。The calculation unit 813 shown in Fig. 18 calculates, for example, the difference between the output of the photosensor 72 during the operation of the circulation pump 71 and the output of the photosensor 72 during the stop of the circulation pump 71 (hereinafter referred to as an output). difference). Here, the operation period and the stop period of the circulation pump 71 may also be defined as "one operation cycle". In order to reduce the influence of the noise contained in the output of the photo sensor 72, the output difference calculated in each operation cycle can also be averaged. The determination unit 814 can determine the degree of foaming of the washing liquid by, for example, comparing the critical value of the output difference of the photosensor 72 stored in the storage unit 816 with the calculation result of the calculation unit 813. By comparing the critical values of the averaged output differences, the effect of noise on the determination of blistering can be reduced. Further, the calculation by the calculation unit 813 is not limited to the difference between the output of the photosensor 72 during the operation of the circulation pump 71 and the output of the photosensor 72 during the stop of the circulation pump 71. Alternatively, other calculations for calculating the rate of change of the output of the photosensor 72 at the start of the operation of the circulation pump 71 or immediately after the stop or the magnitude of the output fluctuation of the photosensor 72 may be used.

控制電路部81具有之記憶部816亦可儲存例如使用作為對光感測器72之輸出差之下限臨界值之第1臨界值、及使用作為上限臨界值之第2臨界值。判定部814可由記憶部816叫出第1臨界值及/或第2臨界值，比較演算部813所算出之光感測器72之輸出差與第1臨界值及/或第2臨界值。當光感測器72之輸出差在第1臨界值以下時，會將控制信號發送到供水系統4，使在清洗步驟及/或沖洗步驟中供水時之供水量，相較於光感測器72之輸出差大於第1臨界值時變得較小。而且，不會供給較多不必要的水，可達成適當的節水。光感測器72之輸出差在第2臨界值以上時，判定部814會對供水系統4之電磁閥發送控制信號，使清洗步驟及/或沖洗步驟中供水時之供水量，相較於光感測器72之輸出差小於第2臨界值時變得較大。而且，洗滌槽3內之洗滌液的液位會上升，在適當的起泡狀態下執行洗滌步驟及/或沖洗步驟。The memory unit 816 included in the control circuit unit 81 can also store, for example, a first critical value used as a lower limit threshold value of the output difference of the photo sensor 72 and a second critical value used as an upper limit critical value. The determination unit 814 can call the first threshold value and/or the second threshold value from the memory unit 816, and compare the output difference of the photo sensor 72 calculated by the calculation unit 813 with the first threshold value and/or the second threshold value. When the output difference of the photo sensor 72 is below the first critical value, the control signal is sent to the water supply system 4, so that the water supply amount during the water supply step in the cleaning step and/or the rinsing step is compared to the photo sensor. When the output difference of 72 is larger than the first critical value, it becomes smaller. Moreover, it does not supply more unnecessary water, and an appropriate water saving can be achieved. When the output difference of the photo sensor 72 is equal to or higher than the second critical value, the determining unit 814 sends a control signal to the solenoid valve of the water supply system 4 so that the water supply amount during the water supply in the washing step and/or the flushing step is compared with the light. When the output difference of the sensor 72 is smaller than the second critical value, it becomes larger. Moreover, the level of the washing liquid in the washing tank 3 rises, and the washing step and/or the rinsing step are performed in an appropriate foaming state.

第20圖係顯示記憶部816具有之對於光感測器72之上限臨界值及下限臨界值之資料構造的一例。與第18圖一併參照第20圖，例示說明可因應洗劑之種類，使用不同之臨界值，判定洗滌液之起泡的手法。Fig. 20 is a view showing an example of a data structure of the upper limit value and the lower limit threshold value of the photo sensor 72 in the memory unit 816. Referring to Fig. 18 together with Fig. 20, a description will be given of a method for determining the foaming of the washing liquid by using different threshold values depending on the type of the lotion.

如第20圖所示，記憶部816係用以儲存每一洗劑種類相對光感測器72之輸出差而異之上限臨界值及下限臨界值。記憶部816進而預先儲存洗滌開始時之供水步驟中之每一洗劑種類之電極感測器73之輸出及光感測器72之輸出之變化的相關資料。自供水開始經過預定時間後，控制電路部81對循環泵71發送控制信號，使循環泵71作動。循環泵71作動期間，演算部813在每一預定時間使電極感測器73及光感測器72之輸出記憶於記憶部816。判定部814比較預先儲存於記憶部816之資料與由演算部813記憶之電極感測器73及光感測器72之輸出，判定洗劑之種類。判定結果記憶於記憶部816。但是，包含沸石之粉末洗劑與一般不包含沸石之液體洗劑中，包含沸石之粉末洗劑由於白濁度較高，因此亦可僅以光感測器72之輸出的比較，判別粉末洗劑與液體洗劑。As shown in FIG. 20, the memory portion 816 is configured to store an upper limit threshold value and a lower limit threshold value for each lotion type relative to the output difference of the photo sensor 72. The memory unit 816 further stores in advance information on the output of the electrode sensor 73 of each lotion type and the change in the output of the photo sensor 72 in the water supply step at the start of washing. After a predetermined time has elapsed since the start of the water supply, the control circuit unit 81 transmits a control signal to the circulation pump 71 to operate the circulation pump 71. During the operation of the circulation pump 71, the calculation unit 813 stores the outputs of the electrode sensor 73 and the photo sensor 72 in the memory unit 816 every predetermined time. The determination unit 814 compares the data stored in advance in the storage unit 816 with the output of the electrode sensor 73 and the photo sensor 72 stored in the calculation unit 813, and determines the type of the lotion. The result of the determination is stored in the memory unit 816. However, in the powder lotion containing zeolite and the liquid lotion generally containing no zeolite, the powder lotion containing zeolite has a higher white turbidity, and therefore the powder lotion can be discriminated only by comparison of the output of the photo sensor 72. With liquid lotion.

例如，第20圖中以「A1」所示之洗劑為粉末洗劑，以「A2」及「A3」所示之洗劑為液體洗劑。此時，對洗劑A1分配之上限臨界值UL1宜設定為比分配到其他洗劑A2或A3之上限臨界值UL2或UL3還大。判定部814判定使用之洗劑為粉末洗劑時，判定部814會自記憶部816讀出上限臨界值UL1，比較演算部813所演算之光感測器72之輸出差與上限臨界值UL1。光感測器72之輸出差大於上限臨界值UL1時，或在上限臨界值UL1以上時，將控制信號發送到供水系統4之電磁閥。該結果是，可比其他洗劑節水來執行沖洗步驟。因此，可對鹼度較高且包含沸石之粉末洗劑，提供適當的沖洗條件。For example, in Fig. 20, the lotion shown by "A1" is a powder lotion, and the lotion shown by "A2" and "A3" is used as a liquid lotion. At this time, the upper limit critical value UL1 for dispensing the lotion A1 is preferably set to be larger than the upper limit critical value UL2 or UL3 assigned to the other lotion A2 or A3. When the determination unit 814 determines that the lotion to be used is a powder lotion, the determination unit 814 reads the upper limit threshold value UL1 from the memory unit 816, and compares the output difference of the photo sensor 72 calculated by the calculation unit 813 with the upper limit critical value UL1. When the output difference of the photo sensor 72 is greater than the upper limit threshold UL1 or above the upper limit threshold UL1, a control signal is sent to the solenoid valve of the water supply system 4. As a result, the rinsing step can be performed in other water than other lotions. Thus, suitable rinsing conditions can be provided for powder lotions having a higher alkalinity and comprising zeolite.

記憶部816進而亦可儲存對應於洗劑種類之清洗時間。例如，相對於液體洗劑A2、A3，分配比粉末洗劑A1較長的清洗時間。判定部814判定使用之洗劑為液體洗劑A2或A3時，演算部813讀出儲存於記憶部816之較長清洗時間之資料，令滾筒式洗衣機1以較長的清洗時間洗滌洗滌物。執行較長時間清洗步驟的結果是，即使是乳化力較小且洗淨效果也較小之液體洗劑A2或A3，也可發揮足夠的洗淨效果。The memory portion 816, in turn, can also store a cleaning time corresponding to the type of lotion. For example, a longer cleaning time than the powder lotion A1 is dispensed with respect to the liquid lotions A2, A3. When the determination unit 814 determines that the lotion to be used is the liquid lotion A2 or A3, the calculation unit 813 reads the data of the long washing time stored in the storage unit 816, and causes the drum type washing machine 1 to wash the laundry with a long washing time. As a result of performing the long-time washing step, even the liquid lotion A2 or A3 having a small emulsifying power and a small washing effect can exert a sufficient washing effect.

再者，判定部814亦可在判定使用之洗劑為粉末洗劑或液體洗劑後，藉由光感測器72之輸出來判定洗劑液之起泡程度。亦可採用將控制信號發送到供水系統4之電磁閥之時序，以在判定為液體洗劑時，相較於判定為粉末洗劑，在洗滌步驟及/或沖洗步驟中減少供水量。依據洗劑量，有時候會有粉末洗劑與液體洗劑以光感測器72判定之起泡程度為同程度之情況，但藉由上述之判定順序以及時序，及使起泡程度為同程度亦可達成因應洗劑種類之節水。再者，判定使用之洗劑為液體洗劑時，亦可執行比判定為粉末洗劑時還長時間之清洗步驟。Further, the determining unit 814 may determine the degree of foaming of the lotion liquid by determining the output of the photosensor 72 after determining whether the lotion to be used is a powder lotion or a liquid lotion. The timing of transmitting the control signal to the solenoid valve of the water supply system 4 may also be employed to reduce the amount of water supply in the washing step and/or the rinsing step when it is determined to be a liquid lotion as compared to the determination of the powder lotion. Depending on the amount of the washing agent, there may be cases where the powder lotion and the liquid lotion are determined to the same degree by the photosensor 72, but by the above-mentioned determination order and timing, and the degree of foaming is the same degree. Water can also be achieved in response to the type of lotion. Further, when it is determined that the lotion to be used is a liquid lotion, a washing step longer than that determined to be a powder lotion may be performed.

上述說明中，用以測定導電度之電極感測器73係例示突出於流路中之感測器，但上述之原理不受限於此，亦可適用於使用任一種必須與洗滌液直接接觸以感測洗滌液之物性之感測器的洗衣機。In the above description, the electrode sensor 73 for measuring the conductivity is exemplified as a sensor protruding from the flow path, but the above principle is not limited thereto, and may be applied to any one that must be in direct contact with the washing liquid. A washing machine for sensing the physical properties of the washing liquid.

上述說明中，光感測器72係用以測定洗滌液之濁度，但亦可使用作為其它之測定目的。上述之原理亦可適用於用以感測髒汙成分之堆積之光感測器72、或可使用光感測器72適當地測定之其他物性或環境變化。In the above description, the photo sensor 72 is used to measure the turbidity of the washing liquid, but it can also be used for other measurement purposes. The above principles can also be applied to photosensors 72 for sensing the accumulation of soiled components, or other physical or environmental changes that can be suitably measured using photosensor 72.

上述說明中，使洗滌液流動之流動裝置係例示泵，但取而代之亦可使用配設在循環路或者流路中之螺槳等使洗滌液流動。In the above description, the flow device for flowing the washing liquid is a pump, but the washing liquid may be flowed by using a propeller or the like disposed in a circulation path or a flow path.

亦可利用因應電信號以開關排水管路74之任意裝置作為排水裝置，以取代本實施形態中例示作為排水裝置之排水閥。又，亦可使用因應電信號以開關供水管路41之任意裝置作為供水裝置，以取代例示作為供水裝置之電磁閥。Instead of the drain valve exemplified as the drain device in the present embodiment, any device that switches the drain line 74 in response to the electric signal may be used as the drain device. Further, any device that switches the water supply line 41 in response to an electric signal may be used as the water supply device instead of exemplifying the electromagnetic valve as the water supply device.

上述之實施形態中，主要係包含具有以下構成之洗衣機。In the above embodiment, the washing machine having the following configuration is mainly included.

上述實施形態之一觀點之洗衣機的特徵在於：特徵在於包含有：洗滌槽，係具有供洗滌液流入之流入口、及供前述洗滌液排出之排出口者；管路，係連接於前述流入口與前述排出口者；流動裝置，係使前述洗滌液通過該管路而由前述排出口朝前述流入口流動者；光感測器，係檢測通過前述管路內之洗滌液之光量者；及控制部，係根據前述光感測器之檢測信號，控制洗滌動作者，其中前述光感測器係用以檢測並輸出前述流動裝置運轉期間之第1光量與前述流動裝置停止期間之第2光量。The washing machine according to one aspect of the present invention is characterized in that the washing machine includes a washing tank having an inlet for supplying the washing liquid and a discharge port for discharging the washing liquid, and a pipe connected to the inlet. And the flow device, wherein the washing liquid passes through the pipe and flows from the discharge port toward the inlet port; and the light sensor detects the amount of light passing through the washing liquid in the pipe; and The control unit controls the washing actor according to the detection signal of the photo sensor, wherein the photo sensor is configured to detect and output the first light amount during the operation of the flow device and the second light amount during the stop of the flow device .

根據上述構成，在洗滌槽內起泡之洗滌液會由洗滌槽之排出口朝管路排出，並且再次由洗滌槽之流入口回到洗滌槽內。在洗滌槽內產生之洗滌液中之泡即使在管路內也不會立刻消失，且會對通過洗滌液之光量造成影響，因此可藉由光感測器適當地測定洗滌液之起泡程度。光感測器用以檢測流動裝置運轉期間之第1光量、與流動裝置停止期間之第2光量，並且將對第1光量及第2光量之檢測信號輸出到控制部。控制部根據檢測信號判定起泡程度，並且控制洗滌動作。因此，控制部可不用等到洗滌液中之泡消失即可判定洗滌液之起泡程度。又，隨著判定時間的縮短，在控制部進行判定期間，水會變得難以補給。而且，起泡之判定變得難以受到補給水的影響。而且，提供一種可快速且正確地感測洗滌液之起泡程度之洗衣機。According to the above configuration, the washing liquid which is foamed in the washing tub is discharged from the discharge port of the washing tub toward the pipe, and is again returned to the washing tub by the inlet of the washing tub. The bubble in the washing liquid generated in the washing tank does not disappear immediately in the pipe, and affects the amount of light passing through the washing liquid, so that the degree of foaming of the washing liquid can be appropriately determined by the photo sensor . The photo sensor detects the first light amount during the operation of the flow device and the second light amount during the stop of the flow device, and outputs a detection signal for the first light amount and the second light amount to the control unit. The control unit determines the degree of foaming based on the detection signal and controls the washing operation. Therefore, the control unit can determine the degree of foaming of the washing liquid without waiting for the bubble in the washing liquid to disappear. Further, as the determination time is shortened, the water becomes difficult to replenish during the determination period by the control unit. Moreover, the determination of the foaming becomes difficult to be affected by the makeup water. Moreover, a washing machine capable of quickly and correctly sensing the degree of foaming of the washing liquid is provided.

上述構成中，前述控制部宜為根據對於前述第1光量之檢測信號與對於前述第2光量之檢測信號之差，判定前述起泡程度並控制前述洗滌動作。In the above configuration, the control unit preferably determines the degree of foaming based on a difference between the detection signal for the first light amount and the detection signal for the second light amount, and controls the washing operation.

根據上述構成，根據對前述第1光量之檢測信號與對前述第2光量之檢測信號的差，控制部判定洗滌液之起泡程度，控制洗滌動作。因此，可判定起泡程度，而不需要複雜的演算或信號處理。因此，可更快速且正確地感測洗滌液之起泡程度。According to the above configuration, the control unit determines the degree of foaming of the washing liquid based on the difference between the detection signal of the first light amount and the detection signal for the second light amount, and controls the washing operation. Therefore, the degree of foaming can be determined without requiring complicated calculations or signal processing. Therefore, the degree of foaming of the washing liquid can be sensed more quickly and correctly.

上述構成中，前述洗衣機宜更具有往前述洗滌槽供水之供水裝置，且前述控制部具有用以記憶相對於前述差之第1臨界值之記憶部，並且前述控制部係控制前述供水裝置，使得當前述差在前述第1臨界值以下時，來自前述供水裝置之供水量會變得比前述差大於前述第1臨界值時還小。In the above configuration, the washing machine preferably further includes a water supply device that supplies water to the washing tub, and the control unit has a memory portion for storing a first critical value relative to the difference, and the control unit controls the water supply device such that the control unit controls When the difference is equal to or less than the first critical value, the amount of water supplied from the water supply device becomes smaller than when the difference is larger than the first critical value.

根據上述構成，當光感測器之檢測信號的差在記憶於記憶部之第1臨界值以下時，控制部會控制供水裝置，並減少來自供水裝置之供水量。光感測器之檢測信號的差變得愈小，洗滌液之起泡程度則變得愈小。當洗滌液之起泡程度小時，必要供水量則小。因此，當檢測信號之差在第1臨界值以下時，藉由減少供水量，可抑制不必要的供水。而且，可得到適當的節水效果。According to the above configuration, when the difference between the detection signals of the photosensors is stored below the first critical value of the memory portion, the control unit controls the water supply device and reduces the amount of water supplied from the water supply device. The difference in the detection signal of the photo sensor becomes smaller, and the degree of foaming of the washing liquid becomes smaller. When the degree of foaming of the washing liquid is small, the necessary water supply amount is small. Therefore, when the difference between the detection signals is below the first critical value, unnecessary water supply can be suppressed by reducing the amount of water supply. Moreover, an appropriate water saving effect can be obtained.

上述構成中，前述記憶部宜更記憶有比前述第1臨界值還大之第2臨界值，且前述控制部係控制前述供水裝置，使得當前述差在前述第2臨界值以上時，來自前述供水裝置之供水量會變得比前述差小於前述第2臨界值時還大。In the above configuration, the memory unit preferably stores a second critical value that is greater than the first critical value, and the control unit controls the water supply device such that when the difference is equal to or greater than the second critical value, the The water supply amount of the water supply device may become larger than when the difference is smaller than the second critical value.

根據上述構成，當光感測器之檢測信號的差在記憶於記憶部之第2臨界值以上時，控制部會控制供水裝置，並加大來自供水裝置之供水量。光感測器之檢測信號之差變得愈大，則洗滌液之起泡程度會變大。洗滌液之起泡程度大時，必要供水量則大。因此，當檢測信號之差在第2臨界值以上時，藉由使供水量增大，可視需要而大量地供水到洗滌槽。而且，達成對洗滌物適合之洗滌動作。According to the above configuration, when the difference between the detection signals of the photosensors is stored above the second critical value of the memory unit, the control unit controls the water supply device and increases the amount of water supplied from the water supply device. The larger the difference between the detection signals of the photosensors, the greater the degree of foaming of the washing liquid. When the degree of foaming of the washing liquid is large, the necessary water supply amount is large. Therefore, when the difference between the detection signals is equal to or higher than the second critical value, a large amount of water is supplied to the washing tub as needed by increasing the amount of water supply. Moreover, a washing action suitable for the laundry is achieved.

上述構成中，前述記憶部宜記憶關於與前述洗滌液所含之洗劑種類對應之前述光量的資料，且前述控制部將來自前述光感測器之輸出信號與前述資料比較，並判定前述洗滌液所含之洗劑種類，前述第2臨界值包含對應於前述洗劑種類為粉末洗劑時之第3臨界值，且前述控制部在判定前述洗劑種類為粉末洗劑時，前述控制部會控制前述供水裝置，使得當前述差為前述第3臨界值以上時，來自前述供水裝置之供水量會變得比前述差小於前述第3臨界值時還大。In the above configuration, the memory unit preferably stores data on the amount of light corresponding to the type of the lotion contained in the washing liquid, and the control unit compares an output signal from the photosensor with the data, and determines the washing. In the type of the lotion to be contained in the liquid, the second critical value includes a third critical value corresponding to the case where the lotion type is a powder lotion, and the control unit determines that the lotion type is a powder lotion, and the control unit The water supply device is controlled such that when the difference is equal to or greater than the third critical value, the water supply amount from the water supply device becomes larger than when the difference is smaller than the third critical value.

根據上述構成，控制部除了判定洗滌液之起泡程度之外，還判定洗滌液所含之洗劑種類。控制部判定洗滌液所含之洗劑種類為粉末洗劑，且光感測器之檢測信號之差比粉末洗劑用所規定之第3臨界值大時，可進行大量的供水。因此，可因應需要而執行降低洗滌液之鹼度及洗滌液中之沸石的濃度。而且，適當地抑制洗滌物之損傷。According to the above configuration, the control unit determines the type of the lotion contained in the washing liquid in addition to the degree of foaming of the washing liquid. The control unit determines that the type of the lotion contained in the washing liquid is a powder lotion, and when the difference between the detection signals of the photosensor is larger than the third critical value prescribed by the powder lotion, a large amount of water supply can be performed. Therefore, the alkalinity of the washing liquid and the concentration of the zeolite in the washing liquid can be reduced as needed. Moreover, the damage of the laundry is appropriately suppressed.

上述構成中，前述洗滌動作宜包含用以清洗洗滌槽內之洗滌物之清洗步驟，且前述控制部在根據來自前述光感測器之輸出信號與前述資料的比較，判定前述洗劑種類為液體洗劑時，使前述清洗步驟執行時間比判定前述洗劑種類為前述液體洗劑以外之洗劑時還長。In the above configuration, the washing operation preferably includes a washing step for washing the laundry in the washing tub, and the control unit determines that the lottery type is liquid based on comparison with an output signal from the photosensor and the data. In the case of the lotion, the execution time of the washing step is longer than when the lotion type is determined to be a lotion other than the liquid lotion.

根據上述構成，控制部判定洗滌液所含之洗劑種類為液體洗劑時，可在較長清洗步驟洗滌洗滌物。因此，即使係乳化力較低且洗淨效果較小之液體洗劑亦可發揮充分的洗滌作用。According to the above configuration, when the control unit determines that the type of the lotion contained in the washing liquid is a liquid lotion, the washing unit can be washed in a long washing step. Therefore, even a liquid lotion having a low emulsifying power and a small washing effect can exert a sufficient washing action.

上述構成中，宜更包含一用以檢測前述洗滌液之導電度並且將檢測信號輸出到前述控制部之導電感測器，前述記憶部更進一步記憶關於與前述洗滌液所含之洗劑種類對應之前述洗滌液之導電度與前述光量之組合的資料，前述控制部將來自前述導電感測器之輸出信號及來自前述光感測器之輸出信號與前述資料比較，判定前述洗滌液所含之洗劑種類。In the above configuration, it is preferable to further include a conductive sensor for detecting the conductivity of the washing liquid and outputting a detection signal to the control unit, wherein the memory portion further memorizes the type of the lotion contained in the washing liquid. The control unit compares the output signal from the conductive sensor and the output signal from the photosensor with the data to determine the combination of the conductivity of the washing liquid and the amount of light. The type of lotion.

根據上述構成，將記憶於記憶部之洗滌液之導電度與光量之組合的相關資料與來自導電感測器及光感測器之檢測信號進行比較之控制部除了可更正確地判定洗滌液之起泡程度之外，還加進洗滌液之導電度，而可更正確地判定洗滌液所含之洗劑種類。一般，使用同量之液體洗劑與粉末洗劑時，由於粉末洗劑相較於液體洗劑，洗滌液的導電度有變高的傾向，因此導電感測器之檢測信號之併用有助於對於對洗劑種類之更正確的判定。According to the above configuration, the control unit that compares the correlation between the conductivity of the washing liquid stored in the memory unit and the amount of light and the detection signal from the conductive sensor and the photo sensor can more accurately determine the washing liquid. In addition to the degree of foaming, the conductivity of the washing liquid is also added, and the type of the lotion contained in the washing liquid can be more accurately determined. Generally, when the same amount of liquid lotion and powder lotion are used, since the powder lotion tends to have a higher conductivity than the liquid lotion, the combination of the detection signals of the conductive sensors contributes to For a more accurate determination of the type of lotion.

上述構成中，前述流動裝置宜進行反覆運轉與停止之間歇動作，前述光感測器在前述流動裝置進行前述間歇動作期間，輸出前述檢測信號，前述控制部將由前述流動裝置之前述運轉與前述停止所構成之運轉周期中之前述檢測信號的差予以平均化，並根據業經前述平均化之前述檢測信號的前述差，判定前述洗滌液之起泡程度。In the above configuration, the flow device preferably performs an intermittent operation of the reverse operation and the stop, and the photo sensor outputs the detection signal during the intermittent operation of the flow device, and the control unit performs the operation and the stop of the flow device. The difference of the detection signals in the configured operation cycle is averaged, and the degree of foaming of the washing liquid is determined based on the difference in the above-described averaged detection signals.

根據上述構成，對第1光量之檢測信號與對第2光量之檢測信號會反覆交互地輸出到控制部。控制部將檢測信號之差平均化，並判定洗滌液之起泡程度。因此，檢測信號所含之雜訊成分會相對變小，可提高對洗滌液之起泡程度之判定的精度。According to the above configuration, the detection signal for the first light amount and the detection signal for the second light amount are alternately output to the control unit. The control unit averages the difference of the detection signals and determines the degree of foaming of the washing liquid. Therefore, the noise component contained in the detection signal is relatively small, and the accuracy of the determination of the degree of foaming of the washing liquid can be improved.

上述構成中，前述流動裝置與前述光感測器之間宜更具有用以除去前述洗滌液所含之髒汙成分之過濾部。In the above configuration, it is preferable that the flow device and the photosensor further have a filter portion for removing the dirt component contained in the washing liquid.

根據上述構成，配置於流動裝置之上游之過濾器部對於洗滌液之流動發揮抵抗的作用。由於過濾器部係位於光感測器之下游，因此對於光感測器進行光量之檢測的影響較小。因此，在流動裝置之運轉中，光感測器可適當地檢測第1光量。又，流動裝置停止後，可比較早期地抑制洗滌液之流動，因此光感測器可安定地檢測第2光量。因此，判定部可更快速且以高精度判定起泡程度。According to the above configuration, the filter portion disposed upstream of the flow device acts to resist the flow of the washing liquid. Since the filter portion is located downstream of the photo sensor, the effect of detecting the amount of light of the photo sensor is small. Therefore, in the operation of the flow device, the photo sensor can appropriately detect the first amount of light. Further, after the flow device is stopped, the flow of the washing liquid can be suppressed relatively early, and therefore the photo sensor can stably detect the second light amount. Therefore, the determination unit can determine the degree of foaming more quickly and with high precision.
