Here, the washing and dissolving process is a process in which the lotion is dissolved in a smaller amount of water than the amount of water in the formal laundry process (refer to step S7) to be described later, and the washing water having a high lotion concentration is generated. The project control unit 72 closes the drain valve 204 and opens the first water supply valve 201, and supplies the lotion to the lotion and the softener case 15 together with water (clean water). The lower portion of the tank 10 closes the first water supply valve 201. Thereafter, the engineering control unit 72 performs control so that the cycle pump motor 211 is reversed. As a result, the circulation pump 210 sucks in the water and the lotion supplied from the suction port 210a, and discharges it from the discharge port 210d. The water and the lotion discharged from the discharge port 210d provided at the front side of the recessed portion 10b flow backward toward the rear side by the inclination of the recessed portion 10b, and face the drain provided at the lowermost portion on the rear side of the recessed portion 10b.

Here, the pre-washing process is a process of immersing the laundry in the washing water having a high concentration of the lotion generated by the lotion dissolution process (refer to step S5). The washing power is increased by soaking the laundry in the washing water having a high detergent concentration. Specifically, the engineering control unit 72 performs control such that the drum 8 is rotated and the circulating pump motor 211 is rotated forward by controlling the motor 9. Thereby, the washing water having a high concentration of the lotion sucked from the drain port 10c (suction port 210a) is ejected from the circulating shower nozzles 140a, 140b to the inside of the drum 8 (that is, the outer tank 10) Thereby, the washing water having a high lotion concentration is infiltrated into the laundry inside the drum 8.
在步驟S7中，工程控制部72，係實行正式洗衣工程。具體而言，工程控制部72，係對於第1供水閥201作控制，並對於外槽10而供水至特定之水位。又，工程控制部72，係以對於馬達9作控制而使滾筒8旋轉並且使循環幫浦馬達211正轉的方式來進行控制。藉由使，來一面將洗衣水澆到滾筒8之內部的洗滌物上，一面將滾筒8之內部的洗滌物作躍動洗衣(beat wash)。 In step S7, the engineering control unit 72 performs a formal laundry project. Specifically, the engineering control unit 72 controls the first water supply valve 201 and supplies water to the outer tank 10 to a specific water level. Moreover, the engineering control unit 72 performs control so that the drum 8 is rotated and the circulating pump motor 211 is rotated forward by controlling the motor 9. By washing the laundry water onto the laundry inside the drum 8, the laundry inside the drum 8 is beat washed.

Here, the so-called cleaning 1 project is a so-called shower cleaning process. The details of the cleaning 1 project in step S8 will be described later using FIG.
在步驟S9中，工程控制部72，係從洗清1工程起而並不使滾筒8之旋轉停止地來實行洗清2工程。在 本實施形態中，於洗清2工程中亦係進行噴淋洗清。另外，針對步驟S9之洗清2工程之詳細內容，係於後使用圖9而作敘述。 In step S9, the engineering control unit 72 performs the washing and cleaning 2 process from the washing 1 project without stopping the rotation of the drum 8. in In the present embodiment, the shower cleaning is also performed in the cleaning 2 project. The details of the cleaning 2 project in step S9 will be described later using FIG.
在步驟S10中，工程控制部72，係實行脫水工程。具體而言，工程控制部72，係將排水閥204開閥，並且對於馬達9作控制而使滾筒8以高速來旋轉，而將洗滌物作離心脫水。之後，若是經過特定之時間，則工程控制部72，係使馬達9停止，並將排水閥204閉閥，而結束洗滌行程(洗衣~洗清~脫水)。 In step S10, the engineering control unit 72 performs a dehydration process. Specifically, the engineering control unit 72 opens the drain valve 204 and controls the motor 9 to rotate the drum 8 at a high speed to centrifugally dewater the laundry. Thereafter, when a specific time has elapsed, the engineering control unit 72 stops the motor 9 and closes the drain valve 204 to end the washing course (laundry-washing-dehydration).
接著，針對步驟S8之洗清1工程，使用圖7而更進一步作說明。圖7，係為本實施形態的滾筒式洗衣機1中之洗清1工程的流程圖。 Next, the cleaning 1 project of step S8 will be further described using FIG. 7. Fig. 7 is a flow chart showing the washing 1 project in the drum type washing machine 1 of the embodiment.
在步驟S801中，工程控制部72，係將排水閥204開閥。藉由此，來將外槽10內之洗衣水排水。 In step S801, the engineering control unit 72 opens the drain valve 204. Thereby, the washing water in the outer tank 10 is drained.
在步驟S802中，工程控制部72，係判定外槽10內之洗衣水的排水是否結束。例如，工程控制部72，係基於設置在排水口10c處之流量感測器(未圖示)的檢測訊號，來判定外槽10內之洗衣水的排水是否結束。當排水並未結束的情況時(S802，No)，工程控制部72係反覆進行步驟S802之處理。當排水結束的情況時(S802，Yes)，工程控制部72之處理係前進至步驟S803。 In step S802, the engineering control unit 72 determines whether or not the drainage of the washing water in the outer tub 10 is completed. For example, the engineering control unit 72 determines whether or not the drainage of the washing water in the outer tub 10 is completed based on the detection signal of the flow rate sensor (not shown) provided at the drain port 10c. When the drainage is not completed (S802, No), the engineering control unit 72 repeats the processing of step S802. When the draining is completed (S802, Yes), the processing of the engineering control unit 72 proceeds to step S803.
在步驟S803中，工程控制部72，係經由馬達驅動電路76而以使滾筒8之旋轉速度會成為第1旋轉速度的方式來對於馬達9之旋轉速度作控制。於此，所謂第1旋轉速度，係為於在對於洗滌物進行洗清前而將在洗滌物中所包含之洗衣水作脫水的中間脫水中之旋轉速度。若是滾筒8之旋轉速度成為第1旋轉速度，則工程控制部72之處理，係前進至步驟S804。 In step S803, the engineering control unit 72 controls the rotational speed of the motor 9 so that the rotational speed of the drum 8 becomes the first rotational speed via the motor drive circuit 76. Here, the first rotation speed is a rotation speed in the intermediate dehydration in which the washing water contained in the laundry is dehydrated before washing the laundry. When the rotation speed of the drum 8 becomes the first rotation speed, the process of the engineering control unit 72 proceeds to step S804.
在步驟S804中，工程控制部72，係判定中間脫水是否結束。例如，工程控制部72，若是從中間脫水開始(步驟S803)起而經過了特定之時間，則係判定中間脫水結束。又，係亦可基於設置在排水口10c處之流量感測器(未圖示)的檢測訊號，來判定中間脫水是否結束。當中間脫水並未結束的情況時(S804，No)，工程控制部72係反覆進行步驟S804之處理。當中間脫水結束的情況時(S804，Yes)，工程控制部72之處理係前進至步驟S805。 In step S804, the engineering control unit 72 determines whether or not the intermediate dehydration is completed. For example, when the engineering control unit 72 has elapsed from the start of the intermediate dehydration (step S803) and the specific time has elapsed, it is determined that the intermediate dehydration is completed. Further, it is also possible to determine whether or not the intermediate dehydration is completed based on the detection signal of the flow rate sensor (not shown) provided at the drain port 10c. When the intermediate dehydration is not completed (S804, No), the engineering control unit 72 repeats the processing of step S804. When the intermediate dehydration is completed (S804, Yes), the process of the engineering control unit 72 proceeds to step S805.
在步驟S805中，工程控制部72，係經由馬達驅動電路76而以使滾筒8之旋轉速度從第1旋轉速度(參考步驟S803)來成為第2旋轉速度(後述之圖8(a)之DV2)的方式，來對於馬達9之旋轉速度作控制(減速)。於此，所謂第2旋轉速度，係為進行噴淋洗清時之旋轉速度，洗滌物係成為貼附在滾筒8之壁面上的狀態。若是滾筒8之旋轉速度成為第2旋轉速度，則工程控制部72之處理，係前進至步驟S806。另外，第2旋轉速 度，係較第1旋轉速度而更低速。另外，第2旋轉速度，係較在積水洗清中之滾筒8的旋轉速度而更高速。 In step S805, the engineering control unit 72 sets the rotation speed of the drum 8 from the first rotation speed (refer to step S803) to the second rotation speed via the motor drive circuit 76 (DV2 of FIG. 8(a) to be described later). The way to control (deceleration) the rotational speed of the motor 9. Here, the second rotation speed is a rotation speed at the time of shower cleaning, and the laundry is attached to the wall surface of the drum 8. When the rotation speed of the drum 8 becomes the second rotation speed, the process of the engineering control unit 72 proceeds to step S806. In addition, the second rotation speed Degree is lower than the first rotation speed. Further, the second rotation speed is higher than the rotation speed of the drum 8 in the water washing.
在步驟S806中，工程控制部72，係將第2供水閥202開閥，並將排水閥204閉閥，且對於循環馬達驅動電路79作控制而使循環幫浦馬達211正轉(ON)。藉由此，係開始噴淋洗清。亦即是，係從清水噴淋噴嘴150而將清水噴射至滾筒8內之洗滌物上，並藉由離心力來將洗滌物內之洗劑成分推出而洗清。又，係藉由將排水閥204閉閥並使循環幫浦210動作，來從循環噴淋噴嘴140a、140b而將洗清水噴射至滾筒8內之洗滌物上，並藉由離心力來將洗滌物內之洗劑成分推出而洗清。 In step S806, the engineering control unit 72 opens the second water supply valve 202, closes the drain valve 204, and controls the circulation motor drive circuit 79 to rotate the cycle pump motor 211 forward (ON). By this, the spray washing is started. That is, the fresh water is sprayed from the clean water spray nozzle 150 to the laundry in the drum 8, and the detergent component in the laundry is pushed out by the centrifugal force to be washed. Further, by closing the drain valve 204 and operating the circulation pump 210, the washing water is sprayed from the circulating shower nozzles 140a and 140b onto the laundry in the drum 8, and the laundry is centrifugally driven. The ingredients in the lotion are introduced and washed.
在步驟S807中，工程控制部72，係判定噴淋洗清是否結束。例如，工程控制部72，若是從噴淋洗清開始起而經過了特定之時間，則係判定噴淋洗清結束。當噴淋洗清並未結束的情況時(S807，No)，工程控制部72之處理係前進至步驟S808。當噴淋洗清結束的情況時(S807，Yes)，工程控制部72之處理係前進至步驟S811。 In step S807, the engineering control unit 72 determines whether or not the shower cleaning is completed. For example, when the engineering control unit 72 has elapsed for a specific period of time from the start of the shower cleaning, it is determined that the shower cleaning is completed. When the shower washing is not completed (S807, No), the processing of the engineering control unit 72 proceeds to step S808. When the shower cleaning is completed (S807, Yes), the processing of the engineering control unit 72 proceeds to step S811.
在步驟S808中，馬達電流值判定部75，係判定藉由馬達電流值檢測裝置62所檢測出之馬達9的電流值(馬達電流值)是否為未滿特定之臨限值(後述之圖8之臨限值TL)。當馬達電流值為未滿臨限值的情況時(S808，Yes)，工程控制部72之處理係前進至步驟S809。當馬達電流值並非為未滿臨限值的情況時(S808， No)，工程控制部72之處理係前進至步驟S810。 In step S808, the motor current value determining unit 75 determines whether or not the current value (motor current value) of the motor 9 detected by the motor current value detecting means 62 is less than a specific threshold value (FIG. 8 described later). The threshold TL). When the motor current value is less than the threshold (S808, Yes), the processing of the engineering control unit 72 proceeds to step S809. When the motor current value is not below the threshold (S808, No), the processing of the engineering control unit 72 proceeds to step S810.
在步驟S809中，工程控制部72，係將第2供水閥202開閥，並將排水閥204閉閥，且對於循環馬達驅動電路79作控制而使循環幫浦馬達211正轉(ON)。之後，工程控制部72之處理係回到步驟S807。另外，當第2供水閥202係已開閥，並將排水閥204閉閥，並且循環幫浦馬達211係正在正轉的情況時，係亦可跳過步驟S809之處理。 In step S809, the engineering control unit 72 opens the second water supply valve 202, closes the drain valve 204, and controls the circulation motor drive circuit 79 to rotate the cycle pump motor 211 forward (ON). Thereafter, the processing of the engineering control unit 72 returns to step S807. Further, when the second water supply valve 202 is opened and the drain valve 204 is closed, and the circulation pump motor 211 is rotating forward, the process of step S809 may be skipped.
在步驟S810中，工程控制部72，係將第2供水閥202閉閥，並將排水閥204開閥，且對於循環馬達驅動電路79作控制而使循環幫浦馬達211停止(OFF)。之後，工程控制部72之處理係回到步驟S807。另外，當第2供水閥202係已閉閥，並將排水閥204開閥，並且循環幫浦馬達211係正停止的情況時，係亦可跳過步驟S810之處理。 In step S810, the engineering control unit 72 closes the second water supply valve 202, opens the drain valve 204, and controls the circulation motor drive circuit 79 to stop the cycle pump motor 211 (OFF). Thereafter, the processing of the engineering control unit 72 returns to step S807. Further, when the second water supply valve 202 is closed and the drain valve 204 is opened, and the circulation pump motor 211 is stopped, the process of step S810 may be skipped.
在步驟S811中，工程控制部72，係將第2供水閥202閉閥，並將排水閥204開閥，且對於循環馬達驅動電路79作控制而使循環幫浦馬達211停止(OFF)。另外，當第2供水閥202係已閉閥，並將排水閥204開閥，並且循環幫浦馬達211係正停止的情況時，係亦可跳過步驟S811之處理。 In step S811, the engineering control unit 72 closes the second water supply valve 202, opens the drain valve 204, and controls the circulation motor drive circuit 79 to stop the cycle pump motor 211 (OFF). Further, when the second water supply valve 202 is closed and the drain valve 204 is opened, and the circulation pump motor 211 is stopped, the process of step S811 may be skipped.
在步驟S812中，工程控制部72，係為了進行中間脫水，而經由馬達驅動電路76來以使滾筒8之旋轉速度從第2旋轉速度(參考步驟S805)而成為第1旋轉 速度的方式，來對於馬達9之旋轉速度作控制(加速)。若是滾筒8之旋轉速度成為第1旋轉速度，則工程控制部72之處理，係前進至步驟S813。 In step S812, the engineering control unit 72 causes the rotation speed of the drum 8 to be the first rotation from the second rotation speed (refer to step S805) via the motor drive circuit 76 in order to perform the intermediate dehydration. The speed is used to control (accelerate) the rotational speed of the motor 9. When the rotation speed of the drum 8 becomes the first rotation speed, the process of the engineering control unit 72 proceeds to step S813.
在步驟S813中，工程控制部72，係判定中間脫水是否結束。例如，工程控制部72，若是從中間脫水開始(步驟S812)起而經過了特定之時間，則係判定中間脫水結束。又，係亦可基於設置在排水口10c處之流量感測器(未圖示)的檢測訊號，來判定中間脫水是否結束。當中間脫水並未結束的情況時(S813，No)，工程控制部72係反覆進行步驟S813之處理。當中間脫水結束的情況時(S813，Yes)，工程控制部72之處理，係結束洗清1工程(圖6之步驟S8)，並前進至洗清2工程(圖6之步驟S9)。 In step S813, the engineering control unit 72 determines whether or not the intermediate dehydration is completed. For example, when the engineering control unit 72 has elapsed from the start of the intermediate dehydration (step S812) and the specific time has elapsed, it is determined that the intermediate dehydration is completed. Further, it is also possible to determine whether or not the intermediate dehydration is completed based on the detection signal of the flow rate sensor (not shown) provided at the drain port 10c. When the intermediate dehydration is not completed (S813, No), the engineering control unit 72 repeats the processing of step S813. When the intermediate dehydration is completed (S813, Yes), the process of the engineering control unit 72 ends the washing 1 project (step S8 of Fig. 6), and proceeds to the washing 2 project (step S9 of Fig. 6).
針對在噴淋洗清中之馬達電流值判定部75的動作例，參考圖7並進而使用圖8而作更進一步之說明。圖8(a)係為對於滾筒之旋轉速度DV的時間變化作展示之圖表，圖8(b)係為對於馬達電流值MI的時間變化作展示之圖表，圖8(c)係為對於外槽之水位WL的時間變化作展示之圖表。 An example of the operation of the motor current value determining unit 75 in the shower cleaning will be further described with reference to FIG. 7 and further to FIG. Fig. 8(a) is a graph showing the temporal change of the rotational speed DV of the drum, and Fig. 8(b) is a graph showing the temporal change of the motor current value MI, and Fig. 8(c) is for the outside The time variation of the water level WL of the tank is shown as a graph.
首先，在中間脫水結束後，如同圖8(a)中所示一般，將滾筒8之旋轉速度從第1旋轉速度來變更(減速)為第2旋轉速度DV2(參考圖7之步驟 S805)。另外，在圖8(a)中，於使旋轉速度減少時，由於係會發生下衝(undershoot)，因此圖8(b)中所示之馬達電流值係暫時性地上升。 First, after the intermediate dehydration is completed, as shown in FIG. 8(a), the rotation speed of the drum 8 is changed (decelerated) from the first rotation speed to the second rotation speed DV2 (refer to the steps of FIG. 7). S805). Further, in Fig. 8(a), when the rotational speed is decreased, an undershoot occurs, so that the motor current value shown in Fig. 8(b) temporarily rises.
在時間T1中，由於滾筒8之旋轉速度係被變更為第2旋轉速度DV2，因此係將第2供水閥202開閥，並將排水閥204閉閥，且使循環幫浦210動作(參考圖7之步驟S806)。 In the time T1, since the rotation speed of the drum 8 is changed to the second rotation speed DV2, the second water supply valve 202 is opened, the drain valve 204 is closed, and the circulation pump 210 is operated (refer to the figure). Step 7 of S806).
從時間T1起而於時間T2中，如同圖8(a)中所示一般，以使滾筒8之旋轉速度DV會以定速(第2旋轉速度DV2)來旋轉的方式而作控制(減速)。又，由於係將排水閥204閉閥，並且係從第2供水閥202而對於外槽10供水，因此如同圖8(c)中所示一般，外槽10之水位WL係緩慢地上升。 From time T1 to time T2, as shown in Fig. 8(a), the rotation speed DV of the drum 8 is rotated at a constant speed (second rotation speed DV2) (deceleration). . Further, since the drain valve 204 is closed and the water is supplied to the outer tub 10 from the second water supply valve 202, the water level WL of the outer tub 10 gradually rises as shown in Fig. 8(c).
於此，如同圖8(b)中所示一般，馬達電流值MI係為略一定，直到水位WL上升至某一程度為止。又，若是水位WL上升至某一程度，則馬達電流值MI亦會上升。此係因為，若是持續對於外槽10供水，則積存於外槽10中之洗清水的水位會上升，並一直到達至作旋轉的滾筒8之外周下側，若是洗清水之水面與作旋轉的滾筒8之外周下側相接觸、亦即是若是洗清水之水位到達滾筒8處，則由於對於馬達9之負載係會變大，因此在以使馬達9之旋轉速度DV以定速(第2旋轉速度DV2)來旋轉的方式而作了控制的情況時，馬達電流值也會變大之故。 Here, as shown in FIG. 8(b), the motor current value MI is slightly constant until the water level WL rises to some extent. Further, if the water level WL rises to a certain level, the motor current value MI also rises. This is because if the water supply to the outer tank 10 is continued, the water level of the washing water accumulated in the outer tank 10 rises and reaches the outer circumference of the drum 8 which is rotated, if it is the surface of the water and the rotation. When the lower side of the outer circumference of the drum 8 is in contact with each other, that is, if the water level of the washing water reaches the drum 8, the load on the motor 9 becomes large, so that the rotation speed DV of the motor 9 is set at a constant speed (second When the rotation speed DV2) is controlled by the rotation method, the motor current value also becomes large.
而，在時間T2中，由於馬達電流值MI係成為臨限值TL以上，因此，馬達電流值判定部75，係在步驟S808中而判定為No，工程控制部72，係將第2供水閥202閉閥而使對於外槽10之供水停止，並且將排水閥204開閥而將外槽10內之洗清水排水。又，工程控制部72係使循環幫浦210停止(參考S810)。 In the time T2, the motor current value MI is equal to or greater than the threshold value TL. Therefore, the motor current value determination unit 75 determines No in step S808, and the engineering control unit 72 sets the second water supply valve. The valve 202 is closed to stop the water supply to the outer tank 10, and the drain valve 204 is opened to drain the washing water in the outer tank 10. Further, the engineering control unit 72 stops the cycle pump 210 (refer to S810).
亦即是，馬達電流值判定部75，係對於馬達電流值作監視，若是馬達電流值成為臨限值以上(S808，No)則對於控制作變更(參考S810)。藉由此，馬達電流值判定部75，係能夠合適地檢測出洗清水之上捲或發泡。 In other words, the motor current value determination unit 75 monitors the motor current value, and if the motor current value is equal to or greater than the threshold value (S808, No), the control is changed (refer to S810). By this, the motor current value determining unit 75 can appropriately detect the winding or foaming of the washing water.
由於外槽10係並不旋轉，因此若是外槽10內之洗清水的水位並未到達滾筒8，則外槽10內之洗清水係略靜止。但是，若是外槽10內之水位到達滾筒8處，則伴隨著正在旋轉之滾筒8，洗清水係會被上捲。若是發生此種洗清水之上捲，則會產生洗清水之攪拌。若是在洗清水中所包含之洗劑濃度係為高，則會有起因於由洗清水之上捲所致之攪拌而導致發泡的發生之虞。 Since the outer tank 10 does not rotate, if the water level of the washing water in the outer tank 10 does not reach the drum 8, the washing water in the outer tank 10 is slightly stationary. However, if the water level in the outer tank 10 reaches the drum 8, the washing water system will be wound up with the drum 8 being rotated. If such a washing water is wound up above, a stirring of the washing water will occur. If the concentration of the lotion contained in the washing water is high, there is a possibility that the foaming occurs due to the agitation caused by the winding of the washing water.
若是起因於發泡所產生的泡泡與加熱器23(參考圖23)等之烘乾系單元接觸、附著，則會有導致烘乾系單元之故障的情形，若是發泡中之洗清水流入至被設置在家中之排水口處，則會從排水口而溢出泡泡，因此係並不理想。 If the bubble generated by the foaming is in contact with and adhered to the drying unit such as the heater 23 (refer to FIG. 23), there is a case where the drying unit is malfunctioning, and if the washing water flows in the foaming When it is set at the drain of the home, it will overflow the bubble from the drain, so it is not ideal.
本實施形態之滾筒式洗衣機1，由於係能夠合 適地檢測出在洗清1工程中之噴淋洗清時的起因於滾筒8(參考圖2)之旋轉所導致的洗清水之上捲和發泡，因此，相較於先前技術之滾筒式洗衣機，係成為能夠將在噴淋洗清時之滾筒8的旋轉速度(馬達9之第2旋轉速度)設定為更高。 The drum type washing machine 1 of the present embodiment is capable of It is suitable to detect the roll and foaming of the washing water caused by the rotation of the drum 8 (refer to FIG. 2) during the washing and cleaning in the washing 1 project, and therefore, compared with the drum washing machine of the prior art The rotation speed of the drum 8 (the second rotation speed of the motor 9) at the time of shower washing can be set higher.
又，本實施形態之滾筒式洗衣機1，係藉由對於馬達電流值作監視，而對於外槽10內之洗清水是否到達滾筒8處一事作監視。而，若是馬達電流值成為了臨限值以上(S808，No)則工程控制部72，係將第2供水閥202閉閥，並將排水閥204開閥，且對於循環馬達驅動電路79作控制而使循環幫浦馬達211停止(OFF)，藉由此來降低外槽10內之洗清水的水位。工程控制部72，係藉由持續使水位降低直到馬達電流值成為未滿臨限值為止(S808，Yes)，來使水位降低直到外槽10內之洗清水的水位成為不會到達滾筒8處的位置。 Further, the drum type washing machine 1 of the present embodiment monitors whether or not the washing water in the outer tub 10 reaches the drum 8 by monitoring the motor current value. On the other hand, if the motor current value is equal to or greater than the threshold value (S808, No), the engineering control unit 72 closes the second water supply valve 202, opens the drain valve 204, and controls the circulation motor drive circuit 79. The circulating pump motor 211 is stopped (OFF), whereby the water level of the washing water in the outer tank 10 is lowered. The project control unit 72 lowers the water level by continuously decreasing the water level until the motor current value becomes less than the threshold (S808, Yes) until the water level of the washing water in the outer tank 10 does not reach the drum 8 s position.
藉由此，係能夠將外槽10內之洗清水的水位保持於不會與滾筒8相接觸之位置，而能夠對於洗清水之捲上作抑制。 Thereby, the water level of the washing water in the outer tank 10 can be maintained at a position where it does not come into contact with the drum 8, and the roll of the washing water can be suppressed.
如同前述一般，在本實施形態中，係藉由判定馬達電流值是否成為臨限值以上，而判定外槽10內之洗清水的水位是否到達滾筒8處。如同前述一般，若是外槽10內之洗清水的水位到達滾筒8處，則由於係會發生洗清水之上捲並導致產生發泡之虞，因此，本實施形態之滾筒式洗衣機1，可以說係藉由對於馬達電流值作監視來對於發泡 可能性之程度作監視。 As described above, in the present embodiment, it is determined whether or not the water level of the washing water in the outer tub 10 reaches the drum 8 by determining whether or not the motor current value is equal to or greater than the threshold value. As described above, if the water level of the washing water in the outer tank 10 reaches the drum 8, the drum type washing machine 1 of the present embodiment can be said because the washing water is wound up and the foaming occurs. Foaming by monitoring the motor current value The degree of possibility is monitored.
另外，在本實施形態中，雖係藉由對於馬達電流值作監視，來對於發泡的可能性之程度作監視，但是，係亦可藉由對於水位感測器63所檢測出的水位作監視，來對於發泡的可能性之程度作監視。 Further, in the present embodiment, the degree of possibility of foaming is monitored by monitoring the motor current value, but the water level detected by the water level sensor 63 can also be used. Monitor to monitor the extent of the possibility of foaming.
接著，針對步驟S9之洗清2工程，使用圖9而更進一步作說明。圖9，係為第1實施形態的滾筒式洗衣機中之洗清2工程的流程圖。 Next, the cleaning 2 project of step S9 will be further described using FIG. Fig. 9 is a flow chart showing the cleaning 2 project in the drum type washing machine of the first embodiment.
在步驟S901中，工程控制部72，係將排水閥204閉閥。 In step S901, the engineering control unit 72 closes the drain valve 204.
之後，在步驟S902中，工程控制部72，係經由馬達驅動電路76，來以使滾筒8之旋轉速度從在圖7之步驟S812以及步驟S813中之第1旋轉速度而成為第2旋轉速度的方式，來對於馬達9之旋轉速度作控制(減速)。如同前述一般，所謂第2旋轉速度，係為進行噴淋洗清時之旋轉速度，洗滌物係成為貼附在滾筒8之壁面上的狀態。又，如同前述一般，第2旋轉速度，係較第1旋轉速度而更低速。 Thereafter, in step S902, the engineering control unit 72 causes the rotational speed of the drum 8 to be the second rotational speed from the first rotational speed in steps S812 and S813 of Fig. 7 via the motor drive circuit 76. In the manner, the rotational speed of the motor 9 is controlled (decelerated). As described above, the second rotation speed is a rotation speed at the time of shower cleaning, and the laundry is attached to the wall surface of the drum 8. Further, as described above, the second rotation speed is lower than the first rotation speed.
在步驟S903中，工程控制部72，係實行柔軟劑投入工程。亦即是，工程控制部72，係一面將滾筒8之旋轉速度從第1旋轉速度來減速為第2旋轉速度，一面進行柔軟劑之投入。柔軟劑投入工程，係進行有與至今為 止之積水洗清相同的工程。具體而言，工程控制部72，係將第1供水閥201開閥，而將被投入至洗劑、柔軟劑盒15中之柔軟劑與清水一同地來供給至外槽10之下部，之後將第1供水閥201閉閥。 In step S903, the engineering control unit 72 performs a softener injection process. In other words, the engineering control unit 72 performs the softener injection while decelerating the rotational speed of the drum 8 from the first rotational speed to the second rotational speed. Softeners are put into engineering, and they are carried out and Stop the same work by washing the water. Specifically, the engineering control unit 72 opens the first water supply valve 201, and supplies the softener charged into the lotion and the softener case 15 to the lower portion of the outer tub 10 together with the clean water, and then The first water supply valve 201 is closed.
若是滾筒8之旋轉速度減速並成為第2旋轉速度，則工程控制部72之處理，係前進至步驟S904。 When the rotational speed of the drum 8 is decelerated and becomes the second rotational speed, the process of the engineering control unit 72 proceeds to step S904.
在步驟S904中，工程控制部72，係在將排水閥204作了閉閥的狀態下，將第2供水閥202開閥，並對於循環馬達驅動電路79作控制而使循環幫浦馬達211正轉(ON)。藉由此，係開始噴淋洗清。亦即是，係從清水噴淋噴嘴150而將清水噴射至滾筒8內之洗滌物上，並藉由離心力來將洗滌物內之洗劑成分推出而洗清。又，係藉由將排水閥204閉閥並使循環幫浦210動作，來從循環噴淋噴嘴140a、140b而將洗清水噴射至滾筒8內之洗滌物上，並藉由離心力來將洗滌物內之洗劑成分推出而洗清。 In step S904, the engineering control unit 72 opens the second water supply valve 202 while the drain valve 204 is closed, and controls the circulating motor drive circuit 79 to cause the circulating pump motor 211 to be positive. Turn (ON). By this, the spray washing is started. That is, the fresh water is sprayed from the clean water spray nozzle 150 to the laundry in the drum 8, and the detergent component in the laundry is pushed out by the centrifugal force to be washed. Further, by closing the drain valve 204 and operating the circulation pump 210, the washing water is sprayed from the circulating shower nozzles 140a and 140b onto the laundry in the drum 8, and the laundry is centrifugally driven. The ingredients in the lotion are introduced and washed.
在步驟S905中，工程控制部72，係判定噴淋洗清是否結束。例如，工程控制部72，若是從噴淋洗清開始起而經過了特定之時間，則係判定噴淋洗清結束。當排水並未結束的情況時(S905，No)，工程控制部72係反覆進行步驟S905之處理。當噴淋洗清結束的情況時(S905，Yes)，工程控制部72之處理係前進至步驟S906。 In step S905, the engineering control unit 72 determines whether or not the shower cleaning is completed. For example, when the engineering control unit 72 has elapsed for a specific period of time from the start of the shower cleaning, it is determined that the shower cleaning is completed. When the drainage is not completed (S905, No), the engineering control unit 72 repeats the processing of step S905. When the shower cleaning is completed (S905, Yes), the processing of the engineering control unit 72 proceeds to step S906.
在步驟S906中，工程控制部72，係將第2供 水閥202閉閥，並將排水閥204開閥，且對於循環馬達驅動電路79作控制而使循環幫浦馬達211停止(OFF)。 In step S906, the engineering control unit 72 sets the second supply. The water valve 202 is closed, and the drain valve 204 is opened, and the circulation motor drive circuit 79 is controlled to stop the cycle pump motor 211.
之後，工程控制部72，係進行圖6之步驟S10中的脫水工程。 Thereafter, the engineering control unit 72 performs the dehydration process in step S10 of Fig. 6.
如此這般，在洗清2工程中，工程控制部72係並不進行馬達電流值之監視。 In this manner, in the cleaning 2 project, the engineering control unit 72 does not monitor the motor current value.
接著，針對第1實施形態之洗清工程，使用圖10來作詳細說明。圖10，係為對於在第1實施形態的洗清工程中之一連串的工程作展示之工程表。另外，圖10中所示之工程表之數值，係為其中一例。 Next, the cleaning process of the first embodiment will be described in detail using FIG. Fig. 10 is a table showing the construction of a series of works in the cleaning process of the first embodiment. In addition, the numerical value of the engineering table shown in FIG. 10 is an example.
另外，如同圖10中所示一般，除了洗清2工程之柔軟劑的投入時(圖10(b)之SB1)以外，由於第1供水閥201係維持於閉閥之狀態，因此係將在除了工程SB1以外時的第1供水閥201之狀態的說明適宜作省略。 In addition, as shown in Fig. 10, in addition to the cleaning of the softening agent of the 2nd process (SB1 of Fig. 10(b)), since the first water supply valve 201 is maintained in the closed state, it will be The description of the state of the first water supply valve 201 other than the engineering SB1 is preferably omitted.
首先，參考圖10(a)，對於洗清1工程作說明。 First, referring to Fig. 10 (a), a description will be given of the washing 1 project.
在工程SA1中，工程控制部72，係藉由以使滾筒8之旋轉速度會成為第1旋轉速度(在圖10中係為1200rpm)的方式來對於馬達9之旋轉速度作控制，而進行中間脫水。於此，工程控制部72，係將第2供水閥202閉閥，並使循環幫浦210停止(「OFF」)。之後，工程控制部72，係將排水閥204設為開閥狀態。工程SA1，係為相當於圖7之步驟S803以及步驟S804的處理。另 外，在圖10之例中，工程SA1(中間脫水)之時間係為120秒。 In the item SA1, the engineering control unit 72 controls the rotation speed of the motor 9 so that the rotation speed of the drum 8 becomes the first rotation speed (1200 rpm in Fig. 10). Dehydration. Here, the engineering control unit 72 closes the second water supply valve 202 and stops ("OFF") the circulation pump 210. Thereafter, the engineering control unit 72 sets the drain valve 204 to the valve open state. The item SA1 is a process equivalent to step S803 and step S804 of Fig. 7 . another Further, in the example of Fig. 10, the time of the project SA1 (intermediate dehydration) is 120 seconds.
之後，在工程SA2中，工程控制部72，係將第2供水閥202設為閉閥狀態，並將循環幫浦210設為停止(「OFF」)狀態，且將排水閥204維持於開閥狀態，而以使滾筒8之旋轉速度會成為第2旋轉速度(在圖10中係為105rpm)的方式來對於馬達9之旋轉速度作控制。亦即是，工程控制部72，係使滾筒8之旋轉速度從第1旋轉速度來減速為第2旋轉速度。在圖10之工程例中，工程SA2之時間，係為滾筒8之旋轉速度的減速時間，其時間係為30秒。又，工程SA2之時間，係兼作為用以排水之時間和等待泡沫消去的時間。另外，工程SA2，係相當於圖7之步驟S805。 Thereafter, in the item SA2, the engineering control unit 72 sets the second water supply valve 202 to the closed state, sets the circulation pump 210 to the "OFF" state, and maintains the drain valve 204 at the valve opening. In the state, the rotational speed of the motor 9 is controlled such that the rotational speed of the drum 8 becomes the second rotational speed (105 rpm in Fig. 10). In other words, the engineering control unit 72 decelerates the rotational speed of the drum 8 from the first rotational speed to the second rotational speed. In the engineering example of Fig. 10, the time of the project SA2 is the deceleration time of the rotational speed of the drum 8, and the time is 30 seconds. In addition, the time of the project SA2 is also used as the time for draining and waiting for the bubble to disappear. Further, the project SA2 corresponds to the step S805 of Fig. 7 .
之後，若是滾筒8之旋轉速度成為第2旋轉速度(在圖10中係為105rpm)，則在工程SA3中，工程控制部72，係在將滾筒8之旋轉速度設為第2旋轉速度(在圖10中係為105rpm)的狀態下，將第2供水閥202設為開閥狀態。又，工程控制部72，係使循環幫浦210正轉(「ON」)，並將排水閥204設為閉閥狀態。藉由此，工程控制部72係進行噴淋洗清。另外，工程SA3，係相當於圖7之步驟S806。 After that, if the rotation speed of the drum 8 becomes the second rotation speed (105 rpm in FIG. 10), in the item SA3, the engineering control unit 72 sets the rotation speed of the drum 8 to the second rotation speed (at In the state of 105 rpm in Fig. 10, the second water supply valve 202 is in an open state. Further, the engineering control unit 72 causes the circulation pump 210 to rotate forward ("ON") and sets the drain valve 204 to the closed state. Thereby, the engineering control unit 72 performs shower cleaning. Further, the item SA3 corresponds to the step S806 of Fig. 7 .
之後，馬達電流值判定部75，係對於馬達9之電流值(馬達電流值)作監視，若是此馬達電流值成為特定之臨限值以上，則工程控制部72，係在工程SA4 中，將滾筒8之旋轉速度維持於第2旋轉速度(在圖10中係為105rpm)，並將第2供水閥202閉閥，且使循環幫浦210停止(「OFF」)，並且將排水閥204開閥。藉由此，來將外槽10內之洗清水排水，外槽10內之水位係下降。另外，工程SA4，係相當於圖7之步驟S808之「No」~步驟S810。 Thereafter, the motor current value determining unit 75 monitors the current value (motor current value) of the motor 9. If the motor current value is equal to or greater than a predetermined threshold value, the engineering control unit 72 is in the engineering SA4. In the middle, the rotation speed of the drum 8 is maintained at the second rotation speed (105 rpm in FIG. 10), the second water supply valve 202 is closed, and the circulation pump 210 is stopped ("OFF"), and the drainage is performed. Valve 204 opens. Thereby, the washing water in the outer tank 10 is drained, and the water level in the outer tank 10 is lowered. Further, the item SA4 corresponds to "No" to step S810 of step S808 of Fig. 7 .
接著，若是外槽10內之水位下降，而馬達電流值回復至未滿特定之臨限值，則工程控制部72，係在工程SA5中，將滾筒8之旋轉速度維持於第2旋轉速度(在圖10中係為105rpm)，並將第2供水閥202開閥，且使循環幫浦210正轉(「ON」)，並且將排水閥204閉閥。工程SA5，係相當於圖7之步驟S808之「Yes」~步驟S809。 Next, if the water level in the outer tank 10 is lowered and the motor current value returns to below the specified threshold value, the engineering control unit 72 maintains the rotation speed of the drum 8 at the second rotation speed in the project SA5 ( In Fig. 10, it is 105 rpm), the second water supply valve 202 is opened, and the circulation pump 210 is rotated forward ("ON"), and the drain valve 204 is closed. The item SA5 corresponds to "Yes" to step S809 of step S808 of Fig. 7.
之後，若是噴淋洗清結束，則工程控制部72，係在工程SA6中，將滾筒8之旋轉速度維持於第2旋轉速度(在圖10中係為105rpm)，並將第2供水閥202閉閥，且使循環幫浦210停止(「OFF」)，並且將排水閥204開閥。此工程SA6，係為用以進行接下來的中間洗清之準備的時間，並相當於圖7之步驟S811。 Thereafter, when the shower cleaning is completed, the engineering control unit 72 maintains the rotation speed of the drum 8 at the second rotation speed (105 rpm in FIG. 10) in the item SA6, and the second water supply valve 202 The valve is closed, and the circulation pump 210 is stopped ("OFF"), and the drain valve 204 is opened. This item SA6 is the time for preparing for the next intermediate washing, and corresponds to step S811 of Fig. 7.
另外，在圖10(a)之工程例中，係將在洗清1工程中之噴淋洗清(工程SA3~SA5)的合計時間設為100秒。亦即是，係構成為：從噴淋洗清開始起直到馬達電流值成為特定之臨限值以上為止的時間(工程SA3之時間)係為48秒，從馬達電流值成為特定之臨限值以上 起直到回復至未滿特定之臨限值為止的時間(工程SA4之時間)係為4秒，進而，從馬達電流值回復至未滿特定之臨限值起直到噴淋洗清結束為止的時間(工程SA5之時間)係為48秒。又，在噴淋洗清之結束後直到移行至接下來的中間脫水為止之移行時間(工程SA6)，係設為4秒。此工程SA6之時間的4秒，係為排水閥204開閥之時間。 Further, in the engineering example of Fig. 10 (a), the total time of the shower washing (engineering SA3 to SA5) in the washing 1 project was set to 100 seconds. In other words, the time from the start of the shower cleaning until the motor current value becomes equal to or greater than the predetermined threshold (time of the project SA3) is 48 seconds, and the motor current value becomes a specific threshold. the above The time until the return to the specified threshold is exceeded (the time of the project SA4) is 4 seconds, and further, the time from the motor current value returning to the expiration of the specific threshold until the end of the spray cleaning (Time of Engineering SA5) is 48 seconds. Further, the travel time (engineering SA6) after the end of the spray washing until the next intermediate dehydration (engineering SA6) is set to 4 seconds. The 4 seconds of the time of this project SA6 is the time when the drain valve 204 is opened.
之後，在工程SA7中，工程控制部72，係在將第2供水閥202閉閥，並使循環幫浦210停止(「OFF」)狀態，且將排水閥204作了開閥的狀態下，藉由以使滾筒8之旋轉速度會成為第1旋轉速度(在圖10中係為1200rpm)的方式來對於馬達9之旋轉速度作控制(加速)，而一面進行排水一面進行中間脫水。在圖10之工程例中，進行中間脫水的時間係被設為60秒。另外，工程SA7，係相當於圖7之步驟S812以及步驟S813。 After that, in the item SA7, the engineering control unit 72 closes the second water supply valve 202, stops ("OFF") the circulation pump 210, and opens the drain valve 204. By controlling (accelerating) the rotational speed of the motor 9 so that the rotational speed of the drum 8 becomes the first rotational speed (1200 rpm in FIG. 10), the intermediate dehydration is performed while draining. In the engineering example of Fig. 10, the time for performing intermediate dehydration was set to 60 seconds. Further, the item SA7 corresponds to the step S812 and the step S813 of Fig. 7 .
以上，洗清1工程係結束。接著，工程控制部72，係並不使滾筒8之旋轉停止地，而前進至圖10(b)中所示之洗清2工程。 Above, the cleaning 1 engineering department is over. Next, the engineering control unit 72 proceeds to the washing and cleaning 2 project shown in FIG. 10(b) without stopping the rotation of the drum 8.
若是進入至洗清2工程，則在工程SB1中，工程控制部72，係從工程SA7之狀態起，將第1供水閥201開閥，並將排水閥204閉閥。又，工程控制部72，係以使滾筒8之旋轉速度會從工程SA7之第1旋轉速度(在圖10中係為1200rpm)而改變為第2旋轉速度(在 圖10中係為105rpm)的方式來對於馬達9之旋轉速度作控制。亦即是，工程控制部72，係使滾筒8之旋轉速度從第1旋轉速度來減速為第2旋轉速度。此時，工程控制部72，係實行柔軟劑之投入工程(圖9之S903)。亦即是，將第1供水閥201開閥，係為為了進行柔軟劑投入之故。在圖10之工程例中，工程SB1之時間係為90秒。於此，將工程SB1之時間設為90秒而成為較洗清1工程之工程SA2之時間(30秒)更長的原因，係因為進行有柔軟劑的投入之故。另外，工程SB2，係相當於圖9之步驟S901~S903。 When the process proceeds to the cleaning 2, the engineering control unit 72 opens the first water supply valve 201 from the state of the item SA7 and closes the drain valve 204. Further, the engineering control unit 72 changes the rotation speed of the drum 8 from the first rotation speed of the work SA7 (1200 rpm in Fig. 10) to the second rotation speed (at In Fig. 10, the mode is 105 rpm) to control the rotational speed of the motor 9. In other words, the engineering control unit 72 decelerates the rotational speed of the drum 8 from the first rotational speed to the second rotational speed. At this time, the engineering control unit 72 performs an input process of the softener (S903 in Fig. 9). That is, the first water supply valve 201 is opened for the purpose of softener injection. In the engineering example of Fig. 10, the time of the project SB1 is 90 seconds. Here, the reason why the time of the project SB1 is 90 seconds is longer than the time (30 seconds) of the process SA2 of the washing 1 project is because the softener is supplied. Further, the project SB2 corresponds to steps S901 to S903 of Fig. 9 .
之後，在工程SB2中，工程控制部72，係在將滾筒8之旋轉速度維持於第2旋轉速度(在圖10中係為105rpm)的狀態下，將第1供水閥201設為閉閥狀態，並將第2供水閥202設為開閥狀態。又，工程控制部72，係使循環幫浦210正轉(「ON」)，並將排水閥204設為閉閥狀態。藉由此，工程控制部72係進行噴淋洗清。另外，工程SB2，係相當於圖9之步驟S904以及步驟S905「No」。 After that, in the item SB2, the engineering control unit 72 sets the first water supply valve 201 to the closed state while maintaining the rotation speed of the drum 8 at the second rotation speed (105 rpm in FIG. 10). And the second water supply valve 202 is in an open state. Further, the engineering control unit 72 causes the circulation pump 210 to rotate forward ("ON") and sets the drain valve 204 to the closed state. Thereby, the engineering control unit 72 performs shower cleaning. Further, the item SB2 corresponds to step S904 of FIG. 9 and step S905 of "No".
之後，若是噴淋洗清結束，則工程控制部72，係在工程SB3中，將滾筒8之旋轉速度維持於第2旋轉速度(在圖10中係為105rpm)，並將第2供水閥202閉閥，且使循環幫浦210停止(「OFF」)，並且將排水閥204開閥。此工程SB3，係為用以進行圖6之脫水工程(S10)之準備的時間，並相當於圖7之步驟S906。 After that, when the shower cleaning is completed, the engineering control unit 72 maintains the rotation speed of the drum 8 at the second rotation speed (105 rpm in FIG. 10) in the item SB3, and the second water supply valve 202 is provided. The valve is closed, and the circulation pump 210 is stopped ("OFF"), and the drain valve 204 is opened. This project SB3 is the time for preparing the dehydration process (S10) of Fig. 6, and is equivalent to step S906 of Fig. 7.
另外，在圖10(b)之工程例中，係將在洗清2工程中之噴淋洗清(工程SB2)的時間設為100秒。在圖10(b)之例中，係為了對於其之與圖10(a)中所示的洗清1工程之間之差異作強調，而將在洗清2工程中之噴淋洗清的時間(工程SB2的時間)區隔成48秒、4秒、48秒，但是，實際上係連續地進行噴淋洗清。又，在噴淋洗清之結束後直到移行至接下來的脫水工程(圖6之S10)為止之移行時間(工程SB3之時間)，係設為4秒。此工程SB3之時間的4秒，係為排水閥204開閥之時間。 Further, in the engineering example of Fig. 10 (b), the time of the shower washing (engineering SB2) in the washing 2 project was set to 100 seconds. In the example of Fig. 10(b), in order to emphasize the difference between the cleaning 1 and the cleaning 1 shown in Fig. 10(a), the spray in the washing 2 project is washed. The time (time of the project SB2) is divided into 48 seconds, 4 seconds, and 48 seconds, but in practice, the shower is continuously washed. Further, the migration time (time of the project SB3) after the completion of the shower washing until the next dehydration process (S10 of Fig. 6) is set to 4 seconds. The 4 seconds of the time of this project SB3 is the time when the drain valve 204 is opened.
若是洗清2工程結束，則工程控制部72，係實行脫水工程(圖6之S10)。在此脫水工程中，工程控制部72，係以使滾筒8之旋轉速度會成為第1旋轉速度(在圖10之工程例中係為1200rpm)的方式來對於馬達9之旋轉速度作控制(加速)。此時，工程控制部72，係將第1供水閥201以及第2供水閥202閉閥，並使循環幫浦210停止，且將排水閥204開閥。另外，脫水工程之時間，係為約330秒。 When the cleaning 2 project is completed, the engineering control unit 72 performs a dehydration process (S10 in Fig. 6). In the dehydration process, the engineering control unit 72 controls the rotational speed of the motor 9 so that the rotational speed of the drum 8 becomes the first rotational speed (1200 rpm in the engineering example of Fig. 10). ). At this time, the engineering control unit 72 closes the first water supply valve 201 and the second water supply valve 202, stops the circulation pump 210, and opens the drain valve 204. In addition, the time of the dewatering process is about 330 seconds.
在洗清1工程之噴淋洗清中，由於係存在有伴隨著洗清水之上捲而導致產生發泡之虞，因此，藉由對於馬達電流值作監視，滾筒式洗衣機1，係將外槽10內之洗清水 的水位維持在不會到達滾筒8處之水位。而，若是外槽10內之水位到達滾筒8處(亦即是，馬達電流值成為了特定之臨限值以上)，則工程控制部72，係藉由將第2供水閥202閉閥並使循環幫浦210停止並且將排水閥204開閥，來降低外槽10內之水位，並對於外槽10內之洗清水的上捲以及起因於洗清水之上捲所導致的發泡作抑制。 In the washing and washing of the washing 1 project, since there is a enthalpy of foaming accompanying the winding of the washing water, the drum type washing machine 1 is externally monitored by monitoring the motor current value. Washing water in tank 10 The water level is maintained at a level that does not reach the drum 8. On the other hand, if the water level in the outer tank 10 reaches the drum 8 (that is, the motor current value is equal to or greater than the specific threshold value), the engineering control unit 72 closes the second water supply valve 202 by The circulation pump 210 is stopped and the drain valve 204 is opened to lower the water level in the outer tank 10, and to suppress the foaming of the washing water in the outer tank 10 and the foaming caused by the winding of the washing water.
相對於此，在洗清2工程中，由於在洗清1工程中，洗清水中的洗劑濃度係成為大幅度降低，因此就算是發生洗清水之上捲，發泡的可能性亦為低。故而，第1實施形態之滾筒式洗衣機1之工程控制部72，在洗清2工程之噴淋洗清中，係藉由持續將第2供水閥202開閥，來持續對於外槽10內供給清水，並且恆常將排水閥204維持於關閉(亦即是，並不對於馬達電流值作監視)地來進行噴淋洗清。 On the other hand, in the washing 2 project, since the concentration of the lotion in the washing water is greatly reduced in the washing 1 project, even if the washing water is wound up, the possibility of foaming is low. . Therefore, the engineering control unit 72 of the drum type washing machine 1 of the first embodiment continues to supply the outer water supply tank 10 by continuously opening the second water supply valve 202 during the washing and cleaning of the washing 2 project. The water is cleaned and the drain valve 204 is constantly maintained in a closed state (i.e., the motor current value is not monitored) for shower cleaning.
若依據第1實施形態之滾筒式洗衣機1，則在洗清2工程之噴淋洗清中，係藉由恆常將第2供水閥202開閥來對於外槽10內供水並且在恆常將排水閥204維持於關閉的狀態下來進行噴淋洗清，而能夠以如同積水洗清一般之在外槽10內積存有洗清水的狀態下來進行噴淋洗清。因此，第1實施形態之滾筒式洗衣機1，係能夠具備有噴淋洗清之洗清性能和積水洗清之洗清性能，而能夠相較於僅進行噴淋洗清以及僅進行積水洗清的情況時來將洗清性能更進一步作提昇。特別是，藉由以噴淋洗清來在將洗清水直接吹附至洗滌物上的狀態下而進行洗清，係能夠 相較於僅進行積水洗清的情況時而將洗清性能更進一步作提昇。 According to the drum type washing machine 1 of the first embodiment, in the shower cleaning of the washing and cleaning 2, the second water supply valve 202 is constantly opened to supply water to the outer tank 10, and it is constant. The drain valve 204 is spray-cleaned while being kept in the closed state, and can be washed and washed in a state where the washing water is accumulated in the outer tub 10 as it is washed with accumulated water. Therefore, the drum type washing machine 1 of the first embodiment can be provided with the washing performance of the shower washing and the washing performance of the water washing, and can be washed only with the shower and only with the water. In the case of the situation, the cleaning performance will be further improved. In particular, it is possible to perform washing by washing with a shower to directly wash the washing water onto the laundry. The cleaning performance is further improved compared to the case where only the water is washed.
另外，雖然在積水洗清中亦係於將排水閥204作了關閉的狀態下而進行洗清，但是，在第1實施形態之洗清2工程中的噴淋洗清、與積水洗清，其滾筒8之旋轉速度係為相異。亦即是，在第1實施形態之滾筒式洗衣機1中，由於係藉由會使洗滌物成為貼附在滾筒8之壁面上的狀態之第2旋轉速度，來進行洗清，因此，係具備有洗劑之推出效果，而能夠相較於僅進行積水洗清的情況時來將洗清性能更進一步作提昇。 In addition, in the case of the water-washing, the drain valve 204 is closed while the drain valve 204 is closed. However, in the washing and cleaning 2 of the first embodiment, the shower is washed and washed with water. The rotational speed of the drum 8 is different. In the drum type washing machine 1 of the first embodiment, since the laundry is cleaned by the second rotation speed in a state in which the laundry is attached to the wall surface of the drum 8, it is provided. There is a lotion effect of the lotion, and the washing performance can be further improved compared to the case where only the water is washed.
圖11，係為對於第1實施形態的滾筒式洗衣機之洗清效果作展示的表。 Fig. 11 is a table showing the cleaning effect of the drum type washing machine of the first embodiment.
另外，在圖11中，比較例係為在專利文獻1中所記載之技術。 In addition, in FIG. 11, the comparative example is the technique described in patent document 1.
又，在圖11中之鹼性度(單位ppm)，係為將進行了洗清1工程、洗清2工程之後的洗滌物以手來擰乾，並對於該擰乾水中所包含的鹼性度作了計測者。若是此鹼性度越低，則代表洗清之效果係為越大。另外，在比較例和本實施形態中，循環幫浦流量均係為40L/min。 In addition, the degree of alkalinity (in ppm) in Fig. 11 is that the laundry which has been subjected to the washing 1 and the cleaning 2 is wrung by hand, and the alkalinity contained in the wrung water is The measure was made. If the alkalinity is lower, the effect of washing is increased. Further, in the comparative example and the present embodiment, the circulation pump flow rate was 40 L/min.
如同圖11中所示一般，相較於在洗清1工程中為進行噴淋洗清並在洗清2工程中為進行積水洗清的比較例中之鹼性度(90ppm)，在洗清1工程以及洗清2工程中為進行了噴淋洗清的本實施形態之滾筒式洗衣機之鹼性度(61ppm)，係在鹼性度上成為有大幅度的降低。 As shown in Fig. 11, in comparison with the alkalinity (90 ppm) in the comparative example in which the washing was performed in the washing 1 project and the water was washed in the washing 2 project, the washing was performed. In the 1st and the cleaning 2, the basicity (61 ppm) of the drum type washing machine of this embodiment which was spray-cleaned was greatly reduced in alkalinity.
又，第1實施形態之滾筒式洗衣機1，由於係能夠將在圖6之步驟S10之脫水工程中的脫水啟動之時間省略，因此相較於洗清2工程乃身為積水洗清的情況，係能夠實現洗滌運轉(洗衣~洗清~脫水)之時間縮短。亦即是，第1實施形態之滾筒式洗衣機1，藉由在洗清2工程中進行噴淋洗清，滾筒8之旋轉速度係成為較積水洗清的旋轉速度而更高速。此事，係代表著，在洗清2工程結束的時間點處，脫水啟動也會結束。藉由此，係能夠將在圖6之步驟S10之脫水工程中的脫水啟動之時間省略，而能夠實現洗滌運轉(洗衣~洗清~脫水)之時間縮短。另外，相較於在專利文獻1(洗清1工程：噴淋洗清，洗清2工程：積水洗清)中所記載的滾筒式洗衣機，第1實施形態之滾筒式洗衣機1，係成為能夠將洗滌運轉時間作1分鐘左右的縮短。 In addition, the drum type washing machine 1 of the first embodiment can omit the start of the dehydration in the dehydration process of the step S10 of Fig. 6, and therefore, it is the case where the washing 2 is cleaned up. The time required for the washing operation (laundry-washing-dehydration) can be shortened. In other words, in the drum type washing machine 1 of the first embodiment, by performing the washing and washing in the washing and cleaning 2, the rotation speed of the drum 8 is higher than the rotation speed of the water washing. This matter is representative of the fact that at the point of completion of the washing 2 project, the start of dehydration will also end. Thereby, the time of dehydration start in the dehydration process of step S10 of FIG. 6 can be abbreviate|omitted, and the time of the washing operation (washing-washing-dehydration) can be shortened. In addition, the drum type washing machine 1 of the first embodiment is capable of being able to be compared with the drum type washing machine described in the patent document 1 (washing 1 project: washing and washing, washing and cleaning 2: water washing). The washing operation time was shortened by about 1 minute.
又，若是將洗清2工程設為積水洗清，則在洗清1工程和洗清2工程之間，係成為需要進行暫時將滾筒8之旋轉停止並使水積存於外槽10內之工程。相對於此，第1實施形態之滾筒式洗衣機1，由於係亦成為並不需要進行在洗清1工程和洗清2工程之間而暫時將滾筒8之旋轉停止並使水積存於外槽10內之工程，因此，相較於在洗清2工程中而進行積水洗清的情況，係能夠實現時間之縮短。 In addition, in the case where the washing and cleaning 2 is set as the water-washing, it is necessary to temporarily stop the rotation of the drum 8 and store the water in the outer tank 10 between the washing 1 and the washing 2 project. . On the other hand, in the drum type washing machine 1 of the first embodiment, it is not necessary to temporarily stop the rotation of the drum 8 between the washing 1 and the cleaning 2, and the water is accumulated in the outer tub 10 Therefore, the time can be shortened compared to the case where the water is washed and washed in the washing 2 project.
又，若是僅將洗清2工程單純地從積水洗清而變更為噴淋洗清，則係有著難以將柔軟劑均等地潑灑的問題。相對於此，第1實施形態之滾筒式洗衣機1，係在洗清2工程之噴淋洗清中，藉由恆常將第2供水閥202開閥來對於外槽10內供水並且在恆常將排水閥204維持於關閉的狀態下來進行噴淋洗清，而能夠以如同積水洗清一般之將洗清水作了積存的狀態下來進行噴淋洗清。藉由此，洗滌物係成為被浸泡在洗清水中的狀態，而能夠使柔軟劑均等地浸透至洗滌物中。 In addition, if only the washing and cleaning 2 is simply washed from the water and changed to the shower washing, there is a problem that it is difficult to uniformly deposit the softening agent. On the other hand, in the drum type washing machine 1 of the first embodiment, the second water supply valve 202 is constantly opened to supply water to the outer tank 10 during the washing and cleaning of the washing 2 project, and is constant. The drain valve 204 is maintained in a closed state, and is spray-washed, and can be washed and washed in a state where the washing water is accumulated as in the case of washing with water. Thereby, the laundry is immersed in the washing water, and the softening agent can be uniformly impregnated into the laundry.
接著，針對第2實施形態之滾筒式洗衣機1的運轉工程，使用圖12以及圖13來作說明。圖12以及圖13，係為對於第2實施形態之滾筒式洗衣機中的洗滌運轉(洗衣~洗清~脫水)之運轉工程作說明之工程圖。 Next, the operation of the drum type washing machine 1 of the second embodiment will be described with reference to Figs. 12 and 13 . FIG. 12 and FIG. 13 are drawings for explaining an operation operation of the washing operation (laundry-washing-dehydration) in the drum type washing machine of the second embodiment.
在圖12以及圖13中，針對與圖6相同之工程，係附加相同之步驟符號，並省略說明。另外，關於滾筒式洗衣機1和控制裝置60之構成，由於係與圖1~圖5中所示者相同，因此係將於此之說明作省略。 In FIGS. 12 and 13 , the same steps as those in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted. In addition, the configuration of the drum type washing machine 1 and the control device 60 is the same as that shown in FIGS. 1 to 5, and thus the description thereof will be omitted.
亦即是，在圖12所示之工程中，係於洗清2工程之後，進行有洗清3工程(S9a)，在圖13所示之工程中， 係於步驟S9a之洗清3工程之後，更進而進行有洗清4工程(S9b)。 That is, in the project shown in Fig. 12, after the cleaning 2 project, the cleaning 3 project (S9a) is performed, and in the project shown in Fig. 13, After the cleaning 3 process in step S9a, the cleaning process 4 is further performed (S9b).
於此情況，係將在複數次之沖洗工程中的並非為最初之洗清工程也非為最後之沖洗工程的洗清工程，稱作中間洗清工程。例如，在圖12所示之工程中，洗清2工程(S9)係成為中間洗清工程。又，在圖13所示之工程中，洗清2工程(S9)和洗清3工程(S9a)係成為中間洗清工程。針對中間洗清工程，係於後再作說明。 In this case, the washing process which is not the initial washing process or the final flushing process in the plurality of flushing processes is called an intermediate washing process. For example, in the project shown in Fig. 12, the washing 2 project (S9) is an intermediate washing process. Further, in the project shown in Fig. 13, the washing 2 project (S9) and the washing 3 project (S9a) are intermediate washing projects. For the intermediate washing project, it will be explained later.
另外，在最後之洗清工程(圖6之洗清2工程(S9)、圖12之洗清3工程(S9a)、圖13之洗清4工程(S9b))中的工程，由於係與圖9中所示之工程相同，因此於此係省略說明。 In addition, in the final cleaning project (Fig. 6 Washing 2 project (S9), Fig. 12 Washing 3 project (S9a), Fig. 13 Washing 4 project (S9b)), due to the system and diagram The engineering shown in Fig. 9 is the same, and therefore the description is omitted here.
接著，針對中間洗清工程，使用圖14來作說明。圖14，係為第2實施形態的滾筒式洗衣機中之中間洗清工程的流程圖。 Next, the intermediate cleaning process will be described using FIG. Fig. 14 is a flowchart showing an intermediate washing process in the drum type washing machine of the second embodiment.
在圖14中，針對與圖9中所示之工程相同之工程，係附加相同之步驟符號，並省略說明。 In FIG. 14, the same steps as those of the construction shown in FIG. 9 are denoted by the same reference numerals, and the description thereof will be omitted.
首先，在圖14中，與圖9中所示之工程相異之點，係在於將排水閥204之閉閥工程(圖9之S901)和柔軟劑投入(圖9之S903)作了省略。 First, in Fig. 14, the point different from the one shown in Fig. 9 is that the valve closing process of the drain valve 204 (S901 of Fig. 9) and the softener input (S903 of Fig. 9) are omitted.
又，在步驟S906之後，於步驟S911中，工程控制部72，係經由馬達驅動電路76，來以使滾筒8之旋轉速度 從第2旋轉速度而成為第1旋轉速度的方式，來對於馬達9之旋轉速度作控制。亦即是，工程控制部72，係使滾筒8之旋轉速度從噴淋洗清用之旋轉速度來加速為中間脫水用之旋轉速度。若是滾筒8之旋轉速度成為第1旋轉速度，則工程控制部72之處理，係前進至步驟S912。 Further, after step S906, in step S911, the engineering control unit 72 causes the rotation speed of the drum 8 via the motor drive circuit 76. The rotation speed of the motor 9 is controlled so as to be the first rotation speed from the second rotation speed. That is, the engineering control unit 72 accelerates the rotational speed of the drum 8 from the rotational speed for shower cleaning to the rotational speed for intermediate dehydration. When the rotation speed of the drum 8 becomes the first rotation speed, the process of the engineering control unit 72 proceeds to step S912.
在步驟S912中，工程控制部72，係判定中間脫水是否結束。例如，工程控制部72，若是從中間脫水開始(步驟S911)起而經過了特定之時間，則係判定中間脫水結束。又，係亦可基於設置在排水口10c處之流量感測器(未圖示)的檢測訊號，來判定中間脫水是否結束。當中間脫水並未結束的情況時(S912，No)，工程控制部72係反覆進行步驟S912之處理。當中間脫水結束的情況時(S912，Yes)，工程控制部72之處理，係結束中間洗清工程，並前進至下一個洗清工程。 In step S912, the engineering control unit 72 determines whether or not the intermediate dehydration is completed. For example, when the engineering control unit 72 has elapsed from the start of the intermediate dehydration (step S911) and the specific time has elapsed, it is determined that the intermediate dehydration is completed. Further, it is also possible to determine whether or not the intermediate dehydration is completed based on the detection signal of the flow rate sensor (not shown) provided at the drain port 10c. When the intermediate dehydration is not completed (S912, No), the engineering control unit 72 repeats the processing of step S912. When the intermediate dehydration is completed (S912, Yes), the process of the engineering control unit 72 ends the intermediate washing process and proceeds to the next washing process.
如此這般，在中間洗清工程中，工程控制部72係並不對於馬達電流值作監視。 As described above, in the intermediate washing process, the engineering control unit 72 does not monitor the motor current value.
接著，針對第2實施形態之中間洗清工程，使用圖15來作詳細說明。圖15，係為對於在第2實施形態的中間洗清工程中之一連串的工程作展示之工程表。另外，圖15中所示之工程表，係為其中一例。另外，在最後之洗清工程(圖6之洗清2工程(S9)、圖12之洗清3工程(S9a)、圖13之洗清4工程(S9b))中的工程表，由 於係與圖10(b)相同，因此於此係省略說明。 Next, the intermediate cleaning process of the second embodiment will be described in detail with reference to Fig. 15 . Fig. 15 is a construction table showing a series of works in the intermediate cleaning process of the second embodiment. In addition, the engineering table shown in FIG. 15 is an example. In addition, in the final cleaning project (Fig. 6 Washing 2 project (S9), Fig. 12 Washing 3 project (S9a), Fig. 13 Washing 4 project (S9b)), This is the same as FIG. 10(b), and thus the description is omitted here.
又，在圖15中，係針對與圖10(b)之工程表相異之工程作說明。在圖15中，係將與圖10(b)之工程表相異之工程以雙重框作標示。 Further, in Fig. 15, a description will be given of a project different from the engineering table of Fig. 10(b). In Fig. 15, a project different from the engineering table of Fig. 10(b) is indicated by a double frame.
首先，在最初之工程SB1a中，工程控制部72，係在將第1供水閥201以及第2供水閥202閉閥，並使循環幫浦210停止(「OFF」)，且將排水閥204開閥的狀態下，以使滾筒8之旋轉速度會成為第2旋轉速度(在圖10中係為105rpm)的方式來對於馬達9之旋轉速度作控制。亦即是，工程控制部72，係使滾筒8之旋轉速度從身為之前的洗清工程之中間脫水之旋轉速度的第1旋轉速度(在圖15中係為1200rpm)來減速為第2旋轉速度(在圖10中係為105rpm)。此工程SB1a之與圖10(b)的工程SB1間之相異點，係在於該工程所被進行的時間為30秒，並且係將排水閥204閉閥。此係因為，與圖10(b)之工程SB1相異，係並不進行柔軟劑的投入之故。另外，工程SB1a，係相當於圖14之步驟S902。又，在工程SB1a中，係亦進行排水。 First, in the first project SB1a, the engineering control unit 72 closes the first water supply valve 201 and the second water supply valve 202, stops the circulation pump 210 ("OFF"), and opens the drain valve 204. In the state of the valve, the rotational speed of the motor 9 is controlled such that the rotational speed of the drum 8 becomes the second rotational speed (105 rpm in Fig. 10). In other words, the engineering control unit 72 decelerates the rotational speed of the drum 8 from the first rotational speed (1200 rpm in FIG. 15) at the rotational speed of dehydration in the middle of the previous washing process to the second rotation. Speed (105 rpm in Figure 10). The difference between this project SB1a and the project SB1 of Fig. 10(b) is that the time taken for the project is 30 seconds, and the drain valve 204 is closed. This is because, unlike the construction SB1 of Fig. 10(b), the softener is not supplied. Further, the project SB1a corresponds to the step S902 of Fig. 14 . In addition, in the project SB1a, drainage is also performed.
另外，如同前述一般，第2旋轉速度，係較第1旋轉速度而更低速。 Further, as described above, the second rotation speed is lower than the first rotation speed.
又，最後，在工程SB4中，工程控制部72，係以使滾筒8之旋轉速度會成為第1旋轉速度(在圖15中係為1200rpm)的方式來對於馬達9之旋轉速度作控制(加速)。此時，工程控制部72，係將第1供水閥201 以及第2供水閥202閉閥，並使循環幫浦210停止(「OFF」)，且將排水閥204開閥。亦即是，工程控制部72，係進行中間脫水。此中間脫水之工程時間(工程SB4之時間)係為60秒。另外，工程SB4，係相當於圖14之步驟S911以及步驟S912。 Finally, in the project SB4, the engineering control unit 72 controls the rotational speed of the motor 9 so that the rotational speed of the drum 8 becomes the first rotational speed (1200 rpm in Fig. 15). ). At this time, the engineering control unit 72 sets the first water supply valve 201 The second water supply valve 202 is closed, the circulation pump 210 is stopped ("OFF"), and the drain valve 204 is opened. That is, the engineering control unit 72 performs intermediate dehydration. The engineering time for this intermediate dewatering (time of project SB4) is 60 seconds. Further, the item SB4 corresponds to the step S911 and the step S912 of Fig. 14 .
另外，在第2實施形態中，雖係將洗清次數設為3次(圖12)、4次(圖13)等，但是，係並不被限定於此，而亦可設為5次以上。就算是洗清次數成為5次以上，亦同樣的，最初之洗清工程，係成為圖7中所示之工程，最後之洗清工程，係成為圖9中所示之工程，並非為最初之洗清工程也非為最後之沖洗工程的洗清工程(中間洗清工程)，係成為圖14中所示之工程。 In addition, in the second embodiment, the number of times of washing is three times (FIG. 12), four times (FIG. 13), and the like, but the present invention is not limited thereto, and may be set to five or more times. . Even if the number of times of washing is 5 or more, the same cleaning process is performed as shown in Fig. 7, and the final cleaning process is the one shown in Fig. 9, which is not the initial one. The washing process is not the finishing of the final flushing project (intermediate washing process), and it becomes the project shown in Fig. 14.
藉由如此這般地將洗清次數進行3次以上，係能夠使洗清性能更加提昇。 By performing the number of times of washing three times or more in this way, the washing performance can be further improved.
接著，針對洗清次數之設定，使用圖16來作說明。圖16，係為對於本實施形態的顯示器以及操作開關的其中一例作展示之圖。 Next, the setting of the number of times of washing is described using FIG. Fig. 16 is a view showing an example of the display and the operation switch of the embodiment.
藉由讓使用者對於身為操作開關13之其中一者的洗清次數設定開關13a進行操作，在顯示器14處係進行有如同圖16中所示一般之洗清次數設定顯示。使用者，係藉由對於身為操作開關13之其中一者的加開關13b以及減開關13c進行操作，而使被顯示在顯示器14處之洗清 次數14a改變，並藉此來設定洗清次數。 By causing the user to operate the cleaning number setting switch 13a which is one of the operation switches 13, a display of the number of times of cleaning as shown in Fig. 16 is performed on the display 14. The user cleans the displayed display 14 by operating the add switch 13b and the down switch 13c, which are one of the operation switches 13. The number 14a is changed, and thereby the number of times of washing is set.
另外，當顯示器14係身為觸控面板式顯示器的情況時，洗清次數設定開關13a和加開關13b以及減開關13c等係亦可身為觸控面板內之開關。 In addition, when the display 14 is a touch panel type display, the cleaning time setting switch 13a, the addition switch 13b, and the reduction switch 13c may be used as switches in the touch panel.
工程控制部72，係依據所設定了的洗清次數14a來實行洗清工程。亦即是，若是洗清次數14a被設定為「2」，則工程控制部72，係進行圖6中所示之洗滌運轉。又，若是洗清次數14a被設定為「3」，則工程控制部72，係進行圖12中所示之選擇運轉，若是洗清次數14a被設定為「4」，則工程控制部72，係進行圖13中所示之選擇運轉。洗清次數14a，係亦可被設定為「5」以上。圖16中所示之洗清次數之設定，係藉由行程選擇(圖6之S1)來進行。 The project control unit 72 performs the washing process in accordance with the set number of washings 14a. In other words, if the number of times of cleaning 14a is set to "2", the engineering control unit 72 performs the washing operation shown in FIG. When the number of cleaning times 14a is set to "3", the engineering control unit 72 performs the selection operation shown in FIG. 12, and if the number of cleaning times 14a is set to "4", the engineering control unit 72 is The selection operation shown in Fig. 13 is performed. The number of times of washing 14a can also be set to "5" or more. The setting of the number of times of washing shown in Fig. 16 is performed by stroke selection (S1 of Fig. 6).
如此這般，藉由成為能夠讓使用者對於洗清次數作設定，係能夠設定與使用者之忙碌與否(在洗滌中所耗費的時間)或者是使用者之喜愛的洗清狀態相對應之洗清次數。 In this way, by making it possible for the user to set the number of times of washing, it is possible to set whether the user is busy or not (the time spent in washing) or the user's favorite washing state. Wash the number of times.
另外，本實施形態之滾筒式洗衣機1，係並不被限定於上述實施形態之構成，在不脫離本發明之要旨的範圍內，係可進行各種之變更。 In addition, the drum type washing machine 1 of the present embodiment is not limited to the configuration of the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
在本實施形態中，雖係將洗清1工程作為噴淋洗清來作了說明，但是，係亦可設為積水洗清。又，係 亦可構成為能夠經由操作開關13來對於要將洗清1工程設為噴淋洗清或者是設為積水洗清一事作設定。 In the present embodiment, the washing 1 project has been described as a shower washing, but it may be a water washing. Again It is also possible to configure the operation of the washing and cleaning process by the operation of the switch 13 or the setting of the water washing.
又，在圖10以及圖15中，雖係將第2旋轉速度(噴淋洗清時之滾筒的旋轉速度)作為105rpm來作了說明，但是，係並不被限定於此，第2旋轉速度，係亦可被設定在430~100rpm之間。又，在圖10以及圖15中，雖係將第1旋轉速度(脫水時之滾筒的旋轉速度)作為1200rpm來作了說明，但是，係並不被限定於此，只要是能夠得到脫水效果，則係亦可將第1旋轉速度設定為1200rpm以下。 In addition, although the second rotation speed (rotation speed of the drum at the time of shower cleaning) is described as 105 rpm in FIG. 10 and FIG. 15 , the present invention is not limited thereto, and the second rotation speed is not limited thereto. The system can also be set between 430 and 100 rpm. In addition, although the first rotation speed (rotation speed of the drum during dehydration) is described as 1200 rpm in FIG. 10 and FIG. 15 , the present invention is not limited thereto, and as long as the dehydration effect can be obtained, The first rotation speed may be set to 1200 rpm or less.
又，滾筒式洗衣機1，係亦可在排水路中具備有未圖示之洗清程度計測感測器，工程控制部72，係亦可在洗清2工程結束之後，讓洗清程度計測感測器對於被排水的洗清水之洗清程度作計測，工程控制部72，係亦可構成為若是該洗清程度係為特定值以上，則實行洗清3工程。又，在洗清3工程結束之後，工程控制部72，係亦能夠以若是洗清程度計測感測器所測定出的洗清程度係為特定值以上則實行洗清4工程一般的方式，而持續實行洗清工程直到洗清水之洗清程度成為未滿特定值為止。 Further, the drum type washing machine 1 may be provided with a washing degree measuring sensor (not shown) in the drain path, and the engineering control unit 72 may also measure the degree of washing after the completion of the washing 2 project. The degree of washing of the drained water to be drained is measured by the measuring device, and the engineering control unit 72 may be configured to perform the washing and cleaning 3 if the degree of washing is a specific value or more. In addition, after the completion of the cleaning 3, the engineering control unit 72 can also perform the cleaning method in the case where the degree of washing measured by the sensor is a specific value or more. The washing process is continued until the washing degree of the washing water becomes less than a specific value.
又，若是被排水的洗清水之洗清程度成為了未滿特定值，則工程控制部72，係亦可構成為藉由投入柔軟劑並進行圖9中所示之工程，來進行最後之洗清工程(噴淋洗清)。 In addition, if the degree of washing of the drained washing water is less than a specific value, the engineering control unit 72 may be configured to perform the final washing by adding a softening agent and performing the work shown in FIG. Clearing the project (spray cleaning).
另外，係亦可構成為能夠讓使用者經由操作開關13 來對於是否要持續實行洗清工程直到洗清程度成為未滿特定值為止一事作設定。 In addition, it can also be configured to allow the user to operate the switch 13 It is necessary to set whether or not to continue the cleaning process until the degree of washing becomes less than a specific value.
又，洗清程度計測感測器，例如係為電極。於此情況，洗清程度計測感測器(電極)，係對於被排水的洗清水之導電度作計測，工程控制部72，係若是此傳導度為特定值以上，則判定為洗清程度係為特定值以上。 Further, the cleaning degree measuring sensor is, for example, an electrode. In this case, the degree of cleaning of the sensor (electrode) is measured for the conductivity of the drained water to be drained, and the engineering control unit 72 determines that the degree of washing is such that the conductivity is a specific value or more. Above a certain value.
本實施形態之滾筒式洗衣機1，雖係作為具備有對於滾筒8內(外槽10內)噴射清水之清水噴淋噴嘴150的構成者來作了說明，但是，係並不被限定於此，亦可為並不具備清水噴淋噴嘴150之構成。例如，噴淋洗清，係亦可為從第1供水閥201來對於外槽10進行供水，並藉由循環幫浦210來從循環噴淋噴嘴140a、140b而對於滾筒8(外槽10)之內部噴射洗清水的構成。 The drum type washing machine 1 of the present embodiment has been described as being composed of a water spray nozzle 150 that sprays clean water into the drum 8 (in the outer tank 10). However, the present invention is not limited thereto. It is also possible to have a configuration in which the fresh water spray nozzle 150 is not provided. For example, in the case of shower cleaning, water supply to the outer tank 10 may be performed from the first water supply valve 201, and the circulation shower nozzles 140a, 140b may be used to circulate the shower nozzles 140a, 140b to the drum 8 (outer tank 10). The internal spray wash water composition.
又，本實施形態之滾筒式洗衣機1，雖係作為若是馬達電流值MI成為臨限值TL以上(S808，No)，則進行將第2供水閥202閉閥，並將排水閥204開閥，且使循環幫浦210停止之控制者，來作了說明，但是，係並不被限定於此。例如，亦可為若是馬達電流值MI成為臨限值TL以上(S808，No)，則僅進行將排水閥204開閥之控制者。當從排水閥204所排水之流量相較於從第2供水閥202而來之供水流量而具有充分之餘裕的情況時，就算是採用此種控制，也能夠使外槽10之水位降低。又，由於在排水閥204之開閥中係亦能夠進行洗滌物之噴淋洗清，因此係能夠更加縮短噴淋洗清之時間。 In the drum type washing machine 1 of the present embodiment, when the motor current value MI becomes equal to or greater than the threshold value TL (S808, No), the second water supply valve 202 is closed, and the drain valve 204 is opened. The controller that stops the cycle pump 210 is described, but is not limited thereto. For example, if the motor current value MI becomes equal to or greater than the threshold value TL (S808, No), only the controller that opens the drain valve 204 may be performed. When the flow rate of the water discharged from the drain valve 204 is sufficient compared to the water supply flow rate from the second water supply valve 202, even if such control is employed, the water level of the outer tank 10 can be lowered. Further, since the washing of the laundry can be performed in the opening of the drain valve 204, the time for the washing and washing can be further shortened.
本發明係並不被限定於前述之實施形態，而亦包含有各種的變形例。例如，在前述之實施形態中，係為為了對於本發明作易於理解之說明而作了詳細說明者，本發明係並不被限定於具備有上述所作了說明的全部之構成者。又，係可將某一實施形態之構成的一部分置換為其他之實施形態的構成，亦可在某一實施形態的構成中追加其他實施形態之構成。又，係可針對各實施形態之構成的一部分，而進行其他之構成的追加、削除或置換。 The present invention is not limited to the above-described embodiments, and various modifications are also included.
