滾筒式洗衣機，是將衣類投入略水平或讓前方向上傾斜的滾筒內進行洗衣工程、洗清工程、脫水工程者。在洗衣工程、洗清工程讓滾筒以低速進行旋轉，進行掀起蓄積在滾筒下方的衣類，讓其從滾筒上方落下的翻滾動作。藉由該翻滾動作，對衣類賦予機械性的力量來進行洗淨及洗清。在脫水工程時讓滾筒以高速進行旋轉，利用旋轉形成的離心力進行從衣類將水分推出到衣類外的離心脫水。 The drum type washing machine is a laundry machine, a washing process, and a dewatering project in which the clothes are put into a drum that is slightly horizontal or inclined upward. In the laundry and washing works, the drum is rotated at a low speed, and the clothes accumulated under the drum are picked up and rolled down from above the drum. By this rolling, the clothing is given mechanical strength to be washed and washed. In the dewatering process, the drum is rotated at a high speed, and the centrifugal force generated by the rotation is used to perform centrifugal dewatering from the clothes to the outside of the clothes.

又，在洗衣工程，利用循環泵吸起洗滌槽(外槽)內的洗滌水澆到衣類，讓洗劑溶掉的洗滌水全面滲透到衣類。如此，滾筒式洗衣機與縱型洗衣機比較即使用少的水也可確保洗淨性能，而可節水。 Further, in the laundry process, the washing water in the washing tank (outer tank) is sucked up by the circulation pump to the clothes, and the washing water in which the lotion is dissolved is completely infiltrated into the clothes.

凹陷部2f是在脫水時，水利用滾筒3的旋轉產生的離心力，從滾筒3的貫穿孔(省略圖示)朝向外槽2的內周面側出去時，接住流到與滾筒3的旋轉方向R同一方向的水，並引導到排水口21。隔壁W是發揮阻止進入到凹陷部2f的水不會再次回到外槽2內的作用效果。 The recessed portion 2f is a centrifugal force generated by the rotation of the water by the drum 3 during dehydration, and catches the rotation to the drum 3 when it exits from the through hole (not shown) of the drum 3 toward the inner peripheral surface side of the outer tub 2. The water in the same direction R is directed to the drain port 21. The partition wall W has an effect of preventing the water entering the recessed portion 2f from returning to the outer tub 2 again.

相對於圖3(b)所示的以往的滾筒式洗衣乾衣機的凹陷部2f的容積在1~1.5L左右，圖3(a)所示的本實施形態的滾筒式洗衣乾衣機S的凹陷部2f的容積被設定成2.5L以上。 The drum type washing machine D of the present embodiment shown in Fig. 3(a) has a volume of about 1 to 1.5 L with respect to the recessed portion 2f of the conventional drum type washer-dryer shown in Fig. 3(b). The volume of the depressed portion 2f is set to 2.5 L or more.

亦即，如由圖3(a)所示的凹陷部2f、與圖3(b)所示的凹陷部2f的對比可知，在本實施形態的凹陷部2f被形成朝外槽2的周向寬幅寬。該凹陷部2f也可設定成外槽2的內徑35%以上的寬幅。 That is, as can be seen from the comparison between the depressed portion 2f shown in Fig. 3(a) and the depressed portion 2f shown in Fig. 3(b), the depressed portion 2f of the present embodiment is formed in the circumferential width of the outer groove 2 width. The recessed portion 2f may be set to have a width of 35% or more of the inner diameter of the outer tub 2.

藉此，滾筒式洗衣乾衣機S外槽2的貯水量比起以往的滾筒式洗衣乾衣機更增大。藉由該凹陷部2f的擴大提高後述的循環泵的旋轉數，而將大流量的洗滌水吸入到循環泵使循環流量增大，結果來說衣類的洗淨效率比以往更進一步地提昇。 Thereby, the amount of water stored in the outer tub 2 of the drum type washer-dryer S is larger than that of the conventional drum type washer-dryer. When the number of rotations of the circulation pump to be described later is increased by the expansion of the recessed portion 2f, the large-flow washing water is sucked into the circulation pump to increase the circulation flow rate, and as a result, the washing efficiency of the clothes is further improved than in the related art.

接著參照的圖4(a)表示從圖1的滾筒式洗衣乾衣機S的外槽的底部朝向循環泵的循環流路的俯視圖，圖4(b)表示從以往的滾筒式洗衣乾衣機的外槽的底部朝向循環泵的循環流路的俯視圖。 4(a) is a plan view showing a circulation flow path from the bottom of the outer tub of the drum-type washer-dryer S of FIG. 1 toward the circulation pump, and FIG. 4(b) shows a conventional drum-type washer-dryer. The bottom of the outer tank faces the top view of the circulation flow path of the circulation pump.

如圖4(a)所示，在本實施形態的排水口21的接頭21a，是形成與蛇腹管22的連接部從排水口21朝向左側突出。而且，蛇腹管22的一端連接於接頭21a，蛇腹管22的另一端連接於循環泵24的入水埠23a。 As shown in Fig. 4 (a), in the joint 21a of the drain port 21 of the present embodiment, the connection portion formed with the bellows 22 protrudes from the drain port 21 toward the left side. Further, one end of the bellows 22 is connected to the joint 21a, and the other end of the bellows 22 is connected to the water inlet 23a of the circulation pump 24.

在本實施形態的蛇腹管22，是構成循環流路的一部分，蛇腹管22的內徑是被設定在35mm以上，理想是被設定在37mm~50mm左右。而且，該蛇腹管22的內徑，是由蛇腹的山徑(蛇腹的狹小部的內徑)被規定。 The bellows tube 22 of the present embodiment is a part of the circulation flow path, and the inner diameter of the bellows tube 22 is set to 35 mm or more, and is preferably set to about 37 mm to 50 mm. Further, the inner diameter of the bellows 22 is defined by the mountain diameter of the bellows (the inner diameter of the narrow portion of the bellows).

又，蛇腹管22的長度是被設定在400mm以下，期望是被設定在150mm~300mm左右。而且，蛇腹管22的長度是由在接頭21a的出口到循環泵24的入水埠 23a的入口之間延伸的蛇腹管22的長度所規定。 Further, the length of the bellows tube 22 is set to 400 mm or less, and it is desirable to set it to about 150 mm to 300 mm. Moreover, the length of the bellows 22 is from the outlet of the joint 21a to the inlet of the circulation pump 24. The length of the bellows tube 22 extending between the entrances of 23a is defined.

如此，在本實施形態，由於蛇腹管22相對於接頭21a的出口從橫向且從循環泵24側被連接，所以可縮短從接頭21a到循環泵24的入水埠23a的入口為止的長度，而使流路阻抗變小。又，由於將位於循環泵24的上游側的蛇腹管22的內徑設成35mm以上比通常更大，所以這點也連結到流路阻抗的減少。因此，詳細雖在後述，可是藉由提高循環泵24的旋轉數，可吸入大流量的洗滌水，讓其循環到滾筒3內。 As described above, in the present embodiment, since the outlet of the bellows 22 with respect to the joint 21a is connected from the lateral direction and from the side of the circulation pump 24, the length from the joint 21a to the inlet of the water inlet 23a of the circulation pump 24 can be shortened. The flow path impedance becomes small. Moreover, since the inner diameter of the bellows tube 22 located on the upstream side of the circulation pump 24 is set to 35 mm or more, it is larger than usual, and this point is also connected to the reduction of the flow path impedance. Therefore, as will be described in detail later, by increasing the number of rotations of the circulation pump 24, it is possible to suck a large amount of washing water and circulate it into the drum 3.

而且，在以往的滾筒式洗衣乾衣機的接頭21a，是如圖4(b)所示，形成與蛇腹管22a的連接部從排水口21朝向後側突出朝向後側突出。而且，在接頭21a與入水埠23a之間延伸存在的以往的蛇腹管22a的長度是在460mm左右，該以往的蛇腹管22a的內徑是在30mm左右。 Further, in the joint 21a of the conventional drum type washer-dryer, as shown in Fig. 4(b), the connection portion formed with the bellows tube 22a protrudes from the drain port 21 toward the rear side toward the rear side. Further, the length of the conventional bellows tube 22a extending between the joint 21a and the water inlet bowl 23a is about 460 mm, and the inner diameter of the conventional bellows tube 22a is about 30 mm.

圖4(a)及(b)中，符號23b是循環泵24的出水埠，符號44是朝向外槽罩蓋2d的後述的循環流路27(參照圖6(a))吐出水的吐出埠，符號45是從循環泵24將水送入到外槽2(凹陷部2f)內的吐出埠。 In (a) and (b) of FIG. 4, the symbol 23b is the water discharge port of the circulation pump 24, and the reference numeral 44 is a discharge port for discharging the water toward the circulation flow path 27 (see Fig. 6(a)) which will be described later on the outer tank cover 2d. Reference numeral 45 is a discharge port that feeds water into the outer tub 2 (recessed portion 2f) from the circulation pump 24.

再回到圖2，在外槽2的後部端面的最下部設有氣阱2e。在氣阱2e的下部設有與外槽2(凹陷部2f)連通的孔2e1，並用管子35連接氣阱2e的上部與水位感應器34檢出外槽2內的水位。而且，在以往的滾筒式洗衣乾衣機，是在排水口21的後部上方設有氣阱2e。循環 水，是從排水口21通過氣阱2e的下方流入蛇腹管22a(參照圖4(b))。因為蛇腹管22a的內徑比本實施形態的蛇腹管22(參照圖4(a))的內徑更狹小，所以增大循環流量時氣阱2e的孔2e1下部的流速變高，依據柏努利的定律會有氣阱2e內的壓力降低而不能正確檢出外槽2內的水位的問題。在本實施形態，因為循環水是從排水口21朝向左側流(參照圖4(a))，所以連通孔2e1部的流速小，氣阱2e內的壓力降低不會發生，因此可正確地檢出外槽2內的水位。 Returning to Fig. 2, a gas trap 2e is provided at the lowermost portion of the rear end surface of the outer tub 2. A hole 2e1 communicating with the outer tub 2 (recessed portion 2f) is provided at a lower portion of the air trap 2e, and the upper portion of the air trap 2e and the water level sensor 34 are connected by a pipe 35 to detect the water level in the outer tub 2. Further, in the conventional drum type washer-dryer, a gas trap 2e is provided above the rear portion of the drain port 21. cycle The water flows into the bellows tube 22a from below the gas trap 2e from the drain port 21 (see Fig. 4(b)). Since the inner diameter of the bellows 22a is narrower than the inner diameter of the bellows 22 (see Fig. 4(a)) of the present embodiment, the flow velocity at the lower portion of the hole 2e1 of the air trap 2e becomes higher when the circulation flow rate is increased, according to Bernu. The law of Lee will have a problem that the pressure in the air trap 2e is lowered and the water level in the outer tank 2 cannot be correctly detected. In the present embodiment, since the circulating water flows from the drain port 21 toward the left side (see FIG. 4(a)), the flow velocity in the communication hole 2e1 portion is small, and the pressure drop in the gas trap 2e does not occur, so that the flow can be accurately detected. The water level in the outer tank 2.

在外槽2與基座1h之間，設有循環泵24、過濾盒23、排水閥25。過濾盒23是在前側具有開口部的圓筒狀，在內部安裝有可裝卸的過濾體(省略圖示)，捕集洗滌水中的異物、線屑。過濾盒23是打開設在下部前面蓋1f的門扇1g，旋轉把手23d而可容易裝卸過濾器(省略圖示)。該過濾盒23是為了作業容易而傾斜使前側變高。 A circulation pump 24, a filter cartridge 23, and a drain valve 25 are provided between the outer tub 2 and the base 1h. The filter cartridge 23 has a cylindrical shape having an opening on the front side, and has a detachable filter body (not shown) attached thereto to collect foreign matter and lint in the washing water. The filter cartridge 23 is opened by opening the door leaf 1g provided on the lower front cover 1f, and the handle 23d is rotated to easily attach and detach the filter (not shown). The filter cartridge 23 is inclined so that the front side becomes high for easy work.

關於以循環泵24為中心的洗滌水的循環系，係在之後詳細說明。 The circulation system of the washing water centering on the circulation pump 24 will be described in detail later.

符號29為烘乾通道，且被配置在筐體1的背面內側。該烘乾通道29，是由橡膠製的蛇腹管29a連接在被設於外槽2的後部的吸氣口。在烘乾通道29內設有水冷除濕機構(未圖示)。 Reference numeral 29 is a drying passage and is disposed inside the back surface of the casing 1. The drying duct 29 is connected to a suction port provided at the rear of the outer tub 2 by a rubber bellows tube 29a. A water-cooling dehumidification mechanism (not shown) is provided in the drying duct 29.

而且，在烘乾運轉時利用未圖示的加熱器、藉由送風扇等將溫風吹入到滾筒3內，使水分從衣類蒸發。成為高溫多濕的空氣，被吸入烘乾通道29，在前述 水冷除濕機構加被冷卻除濕成為低溫空氣，在未圖示的加熱器加被加熱後，被吹入到滾筒3內。此外，也可使用熱泵取代加熱器、水冷除濕機構。 Further, during the drying operation, warm air is blown into the drum 3 by a heater (not shown) by a blower or the like to evaporate water from the clothes. Become hot and humid air, and be sucked into the drying channel 29, in the foregoing The water-cooling dehumidifying mechanism is cooled and dehumidified to become low-temperature air, and is heated in a heater (not shown) and then blown into the drum 3. In addition, a heat pump can be used instead of a heater or a water-cooling dehumidification mechanism.

接著參照的圖5是表示構成圖1的滾筒式洗衣乾衣機的循環機構的循環泵及循環流路的立體圖，圖6是從上觀看循環泵的俯視圖。 5 is a perspective view showing a circulation pump and a circulation flow path constituting a circulation mechanism of the drum-type washer-dryer of FIG. 1, and FIG. 6 is a plan view of the circulation pump viewed from above.

如圖5、圖6所示，循環泵24是具備：與過濾盒23一體被形成的套管42；以及循環泵馬達47所構成。在套管42是如前述形成有：吸入埠43；吐出埠44、45；入水埠23a；以及出水埠23b。 As shown in FIGS. 5 and 6, the circulation pump 24 includes a sleeve 42 integrally formed with the filter cartridge 23, and a circulation pump motor 47. The sleeve 42 is formed as follows: an intake port 43; a discharge port 44, 45; a water inlet port 23a; and a water discharge port 23b.

吸入埠43，是連繫過濾盒23與套管42的略圓形的貫穿孔，且與循環泵24的葉輪46被形成同軸。 The suction port 43 is a substantially circular through hole connecting the filter case 23 and the sleeve 42, and is coaxial with the impeller 46 of the circulation pump 24.

吐出埠44是經由蛇腹管41連繫在被設在外槽罩蓋2d的內側周壁的後述的循環流路27(參照圖7(b))。 The discharge port 44 is connected to a circulation flow path 27 (see FIG. 7(b)) to be described later, which is provided on the inner peripheral wall of the outer tank cover 2d via the bellows 41.

此外，該蛇腹管41及循環流路27，是與前述的蛇腹管22(參照圖4(a))一起構成從外槽的底部到外槽的上部的循環流路。 Further, the bellows tube 41 and the circulation flow path 27 constitute a circulation flow path from the bottom of the outer tank to the upper portion of the outer tank together with the bellows tube 22 (see FIG. 4(a)).

循環流路27，是被連接於被設在外槽罩蓋2d的上方內側的後述噴嘴27a(參照圖7(a))。 The circulation flow path 27 is connected to a nozzle 27a (hereinafter referred to as FIG. 7(a)) which is provided on the upper inner side of the outer tank cover 2d.

吐出埠45是經由蛇腹管40連接於接頭18a。該接頭18a是被設在面臨外槽2的底部的凹陷部2f(參照圖3a)地被形成的流入口18。 The spout 45 is connected to the joint 18a via the bellows tube 40. The joint 18a is an inflow port 18 formed in a recessed portion 2f (see Fig. 3a) facing the bottom of the outer tub 2.

在關閉排水閥25(參照圖2)的狀態下，將洗滌水蓄積在外槽2內，當循環泵24的循環泵馬達47正旋轉 時，外槽2內的洗滌水從排水口21(參照圖3(a))通過蛇腹管22在過濾盒23內的過濾器(省略圖示)去除異物。之後，洗滌水，是從吸入埠43進入循環泵42(圖6的箭頭印F)從吐出埠44被吐出而被送入到循環流路27，並從後述的噴嘴27a(參照圖7(a))灑水到滾筒3(參照圖2)內。 In a state where the drain valve 25 (refer to FIG. 2) is closed, the washing water is accumulated in the outer tub 2, and when the circulation pump motor 47 of the circulation pump 24 is rotating At this time, the washing water in the outer tub 2 removes foreign matter from the drain port 21 (see FIG. 3( a )) through the filter (not shown) in the filter cartridge 23 through the bellows tube 22 . After that, the washing water is discharged from the suction port 43 into the circulation pump 42 (arrow print F in Fig. 6), and is discharged from the discharge port 44 to be sent to the circulation flow path 27, and is described later from the nozzle 27a (see Fig. 7 (a )) Sprinkle water into the drum 3 (refer to Figure 2).

循環泵24的循環泵馬達47逆旋轉時，外槽2內的洗滌水從排水口21(參照圖3(a))通過蛇腹管22在過濾盒23內的過濾器(省略圖示)去除異物。之後，洗滌水，是從吸入埠43進入到循環泵42從吐出埠45被吐出，而經由蛇腹管40及接頭18a從流入口18回到外槽2內。又，打開排水閥25(參照圖2)時，外槽2內的洗滌水通過過濾盒23內的過濾器(省略圖示)從連接於出水埠23b的排水軟管26排水到機外。 When the circulation pump motor 47 of the circulation pump 24 rotates in the reverse direction, the washing water in the outer tub 2 removes the foreign matter from the drain port 21 (see FIG. 3(a)) through the filter (not shown) in the filter cartridge 23 through the bellows tube 22. . Thereafter, the washing water is discharged from the suction port 43 to the circulation pump 42 and discharged from the discharge port 45, and is returned from the inflow port 18 to the outer tub 2 via the bellows pipe 40 and the joint 18a. When the drain valve 25 (see FIG. 2) is opened, the washing water in the outer tub 2 is drained from the drain hose 26 connected to the water discharge port 23b to the outside of the machine through a filter (not shown) in the filter cartridge 23.

且在本實施形態的循環泵馬達47為了確保後述的循環流量而形成可以2000rpm~4200rpm的旋轉數進行旋轉。該旋轉數，是形成如後述由控制裝置38(參照圖2)進行控制。 Further, the circulation pump motor 47 of the present embodiment is configured to rotate at a number of revolutions of 2000 rpm to 4,200 rpm in order to secure a circulating flow rate to be described later. This number of rotations is controlled by the control device 38 (see Fig. 2) as will be described later.

接著，參照圖7(a)表示被設在外槽罩蓋的循環流路的立體圖，圖7(b)表示連接循環泵與被設在外槽罩蓋的循環流路的蛇腹管的立體圖。圖8(a)表示設在外槽罩蓋的循環流路的俯視圖，圖8(b)是連接於循環流路的噴嘴的部分放大圖。圖9為連接於被設在外槽罩蓋的循環流路的噴嘴附近的部分放大立體圖。 Next, a perspective view of a circulation flow path provided in the outer tank cover is shown in Fig. 7(a), and Fig. 7(b) is a perspective view showing a bellows pipe connected to the circulation pump and the circulation flow path provided in the outer tank cover. Fig. 8(a) is a plan view showing a circulation flow path provided in the outer tank cover, and Fig. 8(b) is a partially enlarged view showing the nozzle connected to the circulation flow path. Fig. 9 is a partially enlarged perspective view showing the vicinity of a nozzle which is connected to a circulation flow path provided in the outer tank cover.

如圖7(a)及(b)所示，將其一端連接於循環泵 24的吐出埠44的蛇腹管41，是將其另一端連接於循環流路27的入口埠2g。該入口埠2g是如圖7(b)所示被形成在外槽罩蓋2d的外周面。 As shown in Figure 7 (a) and (b), one end is connected to the circulation pump The bellows 41 of the discharge port 44 of 24 is an inlet port 2g that connects the other end thereof to the circulation flow path 27. This inlet port 2g is formed on the outer peripheral surface of the outer tank cover 2d as shown in Fig. 7 (b).

本實施形態的循環流路27是如圖7(a)所示，由一體被形在樹脂製的外槽罩蓋2d的內側周壁的管狀通路所構成。該循環流路27是沿著外槽罩蓋2d的開口地被形成，且連接於被形成在外槽罩蓋2d的上部的噴嘴27a。本實施形態的循環流路27的剖面形狀雖為四角形，但不限於此，可作成圓形、橢圓形、多角形等。循環流路27的剖面積換算成圓形者直徑相當25mm以上者為期望。 As shown in Fig. 7 (a), the circulation flow path 27 of the present embodiment is constituted by a tubular passage integrally formed on the inner peripheral wall of the outer tank cover 2d made of resin. The circulation flow path 27 is formed along the opening of the outer tank cover 2d, and is connected to the nozzle 27a formed in the upper portion of the outer tank cover 2d. The cross-sectional shape of the circulation flow path 27 of the present embodiment is a quadrangular shape, but is not limited thereto, and may be formed into a circular shape, an elliptical shape, a polygonal shape or the like. It is desirable that the cross-sectional area of the circulation flow path 27 is converted into a circular shape having a diameter of 25 mm or more.

根據本實施形態的循環流路27，由於被設在外槽罩蓋2d的內側周壁，所以與以往之例如由被設在外周壁2d的外側周壁的氯化乙烯管等所形成者不同，破損的虞慮進一步減少，且即使萬一破損，也不會有洗滌水漏出到外槽2的外側的情況。又，循環流路27，由於是將蓋子27c蓋在設在外槽罩蓋2b的溝部27b而形成一體化的構造，所以比以往的物品零件件數可減少。 Since the circulation flow path 27 of the present embodiment is provided on the inner peripheral wall of the outer tank cover 2d, it is different from the conventional one formed by a vinyl chloride tube or the like provided on the outer peripheral wall of the outer peripheral wall 2d. Further consideration is made, and even if it is broken, there is no case where the washing water leaks to the outside of the outer tub 2. Further, since the circulation flow path 27 is formed by integrating the lid 27c in the groove portion 27b provided in the outer tank cover 2b, the number of parts of the article can be reduced.

噴嘴27a是將從循環泵24(參照圖5)的吐出埠44所吐出的洗滌水從外槽罩蓋2d的上部朝向滾筒3(參照圖2)內噴射者。 The nozzle 27a ejects the washing water discharged from the discharge port 44 of the circulation pump 24 (see FIG. 5) from the upper portion of the outer tank cover 2d toward the drum 3 (see FIG. 2).

該噴嘴27a是如圖9所示，其開口形成細縫狀，而可使洗滌水展開呈薄膜狀進行噴射，並灑水到滾筒內的廣泛的範圍。又，由於洗滌水的循環流量比以往增加，所以即使比以往更加寬該噴嘴27a的細縫寬幅(間隙 寬幅)噴射的力道也不會有減弱的情況。因此，可將該細縫寬幅(間隙寬幅)設在3mm以上，而能更確實地防止因線屑等造成噴嘴27a的堵塞。此外，在噴嘴27a的波紋管10側形成有整流部27g，來將洗滌水朝向滾筒3的深側噴射。藉此，可將洗滌水從滾筒3內的前側灑水到深側的衣類。 As shown in Fig. 9, the nozzle 27a has a slit formed in a slit shape, and the washing water can be sprayed in a film form to be sprayed and sprinkled into a wide range of the drum. Further, since the circulating flow rate of the washing water is increased as compared with the prior art, the slit width (gap) of the nozzle 27a is wider than ever. The width of the spray) does not diminish. Therefore, the slit width (gap width) can be set to 3 mm or more, and clogging of the nozzle 27a due to swarf or the like can be more reliably prevented. Further, a rectifying portion 27g is formed on the bellows 10 side of the nozzle 27a to eject the washing water toward the deep side of the drum 3. Thereby, the washing water can be sprinkled from the front side in the drum 3 to the clothing on the deep side.

又，在外槽罩蓋2d也可形成與循環流路27連通的小孔H鄰接於噴嘴27a。洗滌水通過循環流路27從噴嘴27a被噴射之際，從該小孔H朝向波紋管10的裏側噴射洗滌水。從該小孔H被噴射的洗滌水在波紋管10的裏側從上部朝向下部流的時候，可洗去附著在波紋管10的裏側的線屑等。 Further, the outer groove cover 2d may have a small hole H that communicates with the circulation flow path 27 to be adjacent to the nozzle 27a. When the washing water is sprayed from the nozzle 27a through the circulation flow path 27, the washing water is sprayed from the small hole H toward the back side of the bellows 10. When the washing water sprayed from the small hole H flows from the upper portion toward the lower portion on the back side of the bellows 10, the wire scraping or the like adhering to the back side of the bellows 10 can be washed away.

從循環流路27對噴嘴27a的連接，是如圖8(b)的一點鏈線所示，作為平順的曲線之側因為壓力損失可減少，所以為了確保流量而理想。可是，用箭頭印50表示的洗滌水，因為是沿著外槽罩蓋2d的開口流過來，所以在離心力的作用下成為偏向壁27e側的水流(箭頭印50a)，而不能往滾筒3內均勻地進行灑水。於此，形成在噴嘴27a的上游側藉由壁27d讓循環流路27彎曲呈略90度，而在面對噴嘴27a展開呈扇形的壁27e、壁28f的位置連接於噴嘴27a。洗滌水，是碰觸到壁27d而使流向急遽彎曲，並藉由碰觸到壁27d所產生的動壓，可分配往壁27f的循環水。藉此，洗滌水是展開成由箭頭印50a、50b所示的範圍的扇形，往滾筒3內均勻地被噴射，而可沒有 不均地將洗滌水灑到衣類。 The connection from the circulation flow path 27 to the nozzle 27a is as shown by the one-dot chain line in Fig. 8(b), and since the pressure loss can be reduced as the smooth curve side, it is preferable to secure the flow rate. However, since the washing water indicated by the arrow mark 50 flows along the opening of the outer tank cover 2d, the water flow on the side of the deflecting wall 27e (the arrow mark 50a) is exerted by the centrifugal force, and the drum 3 cannot be moved into the drum 3. Sprinkle water evenly. On the upstream side of the nozzle 27a, the circulation flow path 27 is bent by 90 degrees by the wall 27d, and is connected to the nozzle 27a at a position where the fan 27a and the wall 28f are formed to face the nozzle 27a. The washing water is in contact with the wall 27d to cause the flow to be sharply bent, and by the dynamic pressure generated by the wall 27d, the circulating water to the wall 27f can be distributed. Thereby, the washing water is fan-shaped in a range shown by the arrow marks 50a, 50b, and is uniformly sprayed into the drum 3, but there is no The washing water is sprinkled unevenly on the clothes.

接著，針對控制裝置38(參照圖2)進行說明。控制裝置38具備微電腦、驅動電路等，並且也具備圖2所示的操作按鈕12、13的開閉訊號、從各種感應器的輸出訊號的輸入電路等。又，微電腦接受使用者的操作；在洗滌工程、烘乾工程的各種情報訊號。微電腦是經由驅動電路連接於馬達4、給水電磁閥16、排水閥25、送風扇(省略圖示)等，來控制該等的開閉、旋轉、通電。又，為了告知使用者關於滾筒式洗衣乾衣機S的情報，也控制顯示器14、蜂鳴器(省略圖示)等。 Next, the control device 38 (see FIG. 2) will be described. The control device 38 includes a microcomputer, a drive circuit, and the like, and also includes an open/close signal of the operation buttons 12 and 13 shown in FIG. 2, an input circuit for outputting signals from various sensors, and the like.

Further, in order to inform the user of the information on the drum type washing and drying machine S, the display 14 and the buzzer (not shown) are also controlled.

<<第1實施形態的運轉工程>> <<Operation Engineering of the First Embodiment>>

接著，使用圖10針對第1實施形態的滾筒式洗衣乾衣機S的運轉工程進行說明。圖10是說明第1實施形態的滾筒式洗衣乾衣機S的洗滌運轉(洗衣~洗清~脫水)的運轉工程的工程圖。 Next, the operation of the drum-type washer-dryer S of the first embodiment will be described with reference to Fig. 10 . FIG. 10 is a view showing an operation of the washing operation (laundry-washing-dehydration) of the drum-type washer-dryer S of the first embodiment.

在步驟S1，控制裝置38接受滾筒式洗衣乾衣機S的運轉工程的行程選擇輸入(行程選擇)。於此，使用者打開門扇9，將洗滌的衣類投入滾筒3的內部，關閉門扇9。然後，使用者藉由操作操作開關12、13，選擇運轉工程的行程進行輸入。藉由操作操作開關12、13，將所選擇的運轉工程的行程輸入到控制裝置38。控制裝置38，是依據所輸入的運轉工程的行程，從運轉模式資料庫讀取對應的運轉模式，進入到步驟S2。此外，在以下的 說明，作為選擇了標準行程(洗衣~洗清2次~脫水)進行說明。 In step S1, the control device 38 accepts the stroke selection input (stroke selection) of the operation of the drum type washer-dryer S. Here, the user opens the door leaf 9, puts the washed clothes into the inside of the drum 3, and closes the door leaf 9. Then, the user selects the stroke of the operation project to input by operating the operation switches 12 and 13. The stroke of the selected operational project is input to the control device 38 by operating the operation switches 12, 13. The control device 38 reads the corresponding operation mode from the operation mode database in accordance with the stroke of the input operation project, and proceeds to step S2. In addition, in the following It is explained that the standard stroke (washing - washing 2 times - dehydration) is selected.

在步驟S2，控制裝置38執行檢出被投入滾筒3的衣類的重量(布量)的工程(布量檢測)。具體而言，控制裝置38，是驅動馬達4讓滾筒3旋轉的同時，衣類重量算出部算出注水前的衣類的重量(布量)。 In step S2, the control device 38 performs a process (amount of cloth detection) for detecting the weight (amount of cloth) of the clothes to be fed into the drum 3. Specifically, the control device 38 calculates the weight (amount of cloth) of the clothes before water injection while the drive motor 4 rotates the drum 3 .

在步驟S3，控制裝置38，是執行算出洗劑量‧運轉時間的工程(洗劑量運轉時間算出)。具體而言，控制裝置38，是控制給水電磁閥16(例如打開第3電磁閥)，對外槽2的給水口2a進行直接給水。控制裝置38的電導率測定部，是經由被配置在外槽2的內底部的電導率感應器(未圖示)檢出被給水的電導率(硬度)。又，利用溫度感應器檢出被給水的水的溫度。之後，控制給水電磁閥16(例如關閉第3電磁閥)，結束對外槽2的給水。 In step S3, the control device 38 executes a process of calculating the washing dose ‧ the operation time (the calculation of the washing dose operation time). Specifically, the control device 38 controls the water supply solenoid valve 16 (for example, opens the third electromagnetic valve), and directly supplies water to the water supply port 2a of the outer tub 2. The conductivity measuring unit of the control device 38 detects the conductivity (hardness) of the supplied water via a conductivity sensor (not shown) disposed at the inner bottom of the outer tank 2. Further, the temperature of the water supplied to the water is detected by a temperature sensor. Thereafter, the water supply solenoid valve 16 is controlled (for example, the third electromagnetic valve is closed), and the water supply to the outer tank 2 is ended.

控制裝置38的洗劑量‧洗衣時間決定部，是依據在步驟S2所檢出的布量、水的電導率(硬度)、水的溫度，藉由圖像檢索(map search)決定投入的洗劑量與運轉時間。然後，控制裝置38將所決定的洗劑量‧運轉時間顯示在顯示器14。此外，雖作成檢出對外槽2給水的水的電導率(硬度)及水溫者進行說明，可是並不限定於此。例如，將前次運轉時的水的電導率(硬度)及水溫記憶在微電腦的記憶部(未圖示)，且也可使用這個。 The washing dose ‧ laundry time determining unit of the control device 38 determines the amount of washing to be charged by image search based on the amount of cloth detected in step S2, the conductivity (hardness) of water, and the temperature of water. With running time. Control device 38 then displays the determined wash dose ‧ run time on display 14 . In addition, although the electric conductivity (hardness) and the water temperature of the water supplied to the outer tank 2 are described, it is not limited to this. For example, the conductivity (hardness) and water temperature of the water during the previous operation are stored in the memory unit (not shown) of the microcomputer, and this can also be used.

在步驟S4，控制裝置38是執行洗劑投入等待工程(洗劑投入等待工程)。例如，控制裝置38進行預定 時間待機，便進入步驟S5。使用者，是參考待機中被顯示在顯示器14的洗劑量，將洗劑類放入洗劑承盤7內。此外，控制裝置38，也可構成設置感測洗劑承盤7的開閉的手段(未圖示)，在打開洗劑承盤7之後關閉時視為有投入洗劑類而進到步驟S5。 At step S4, the control device 38 executes the lotion input waiting process (the lotion input waiting for the project). For example, the control device 38 makes a reservation When the time is on, the process proceeds to step S5. The user refers to the washing amount displayed on the display 14 during standby, and puts the lotion into the lotion holder 7. Further, the control device 38 may be configured to provide means (not shown) for sensing the opening and closing of the lotion retainer 7, and when it is closed after the lotion retainer 7 is opened, it is regarded as having a lotion, and the process proceeds to step S5.

在步驟S5，控制裝置38是執行洗劑溶解工程(洗劑溶解工程)。例如，控制裝置38，是控制給水電磁閥16(例如打開第1電磁閥)經由給水管對粉末洗劑投入室以及液體洗劑投入室進行給水。粉末洗劑投入室以及液體洗劑投入室的洗劑與水，是經由洗劑送出管、蛇腹管20、位在外槽2的後側上部的給水口2a、被形成在外槽2的底壁52內面的給水路徑，從其出口流入外槽2的凹陷部2f。給水到預定水量時，控制裝置38控制給水電磁閥16(例如關閉第1電磁閥)令給水停止。然後，控制裝置38執行洗劑溶解動作(洗劑溶解動作)。具體而言，控制裝置38，是控制使循環泵24以預定的旋轉數進行逆旋轉，將從排水口21經由蛇腹管22所吸入水與洗劑經由蛇腹管40從凹陷部2f的流入口18吐出。從流入口18被吐出的水與洗劑，是形成在凹陷部2f流而朝向排水口21進行循環。藉此，攪拌水與洗劑，而形成洗劑溶解在水裡。經過預定時間(例如10秒)時，控制裝置38令循環泵24停止進到步驟S6。 At step S5, the control device 38 performs a lotion dissolution process (lotion dissolution process). For example, the control device 38 controls the water supply solenoid valve 16 (for example, opens the first electromagnetic valve) to supply water to the powder detergent supply chamber and the liquid detergent supply chamber via the water supply pipe. The lotion and water in the powder lotion-input chamber and the liquid lotion-input chamber are via a lotion delivery tube, a bellows tube 20, a water supply port 2a located at an upper portion of the rear side of the outer tub 2, and a bottom wall 52 formed in the outer tub 2 The water supply path of the inner surface flows into the recessed portion 2f of the outer tank 2 from the outlet thereof. When the water is supplied to the predetermined amount of water, the control device 38 controls the feed water solenoid valve 16 (for example, closing the first solenoid valve) to stop the feed water. Then, the control device 38 performs a lotion dissolution operation (lotion dissolution action). Specifically, the control device 38 controls the circulation pump 24 to reversely rotate at a predetermined number of rotations, and sucks water and detergent from the drain port 21 through the bellows tube 22 through the bellows tube 40 from the inflow port 18 of the recessed portion 2f. Spit out. The water and the lotion which are discharged from the inflow port 18 are formed in the recessed portion 2f and circulate toward the drain port 21. Thereby, the water and the lotion are stirred to form a lotion dissolved in the water. When a predetermined time (for example, 10 seconds) elapses, the control device 38 causes the circulation pump 24 to stop to proceed to step S6.

在步驟S6，控制裝置38是執行旋轉給水工程(旋轉給水工程)。具體而言，控制裝置38，是控制給水電 磁閥16(例如打開第1電磁閥與第3電磁閥)，使外槽2內的洗衣水的水位上升，並且控制馬達4讓滾筒3以預定的旋轉數(例如40rpm)(參照圖10)進行旋轉，來進行衣類的翻轉，並且控制使循環泵24以預定的旋轉數(例如3000rpm)(參照圖10)進行正旋轉，而將從排水口21所吸入的洗劑濃度高的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，藉此滲入到滾筒3的內部的衣類。 At step S6, the control device 38 executes a rotary water supply project (rotary water supply project). Specifically, the control device 38 controls the water and electricity The magnetic valve 16 (for example, opening the first electromagnetic valve and the third electromagnetic valve) raises the water level of the washing water in the outer tub 2, and controls the motor 4 to let the drum 3 have a predetermined number of revolutions (for example, 40 rpm) (refer to FIG. 10). Rotation is performed to perform the inversion of the clothes, and the circulation pump 24 is controlled to rotate positively at a predetermined number of rotations (for example, 3000 rpm) (refer to FIG. 10), and the washing water having a high concentration of the lotion sucked from the drain port 21 is The nozzle 27a provided in the opening of the outer tub 2 is discharged into the inside of the drum 3, thereby infiltrating into the inside of the drum 3.

而且，當外槽2內的洗衣水的水位上昇到預定的水位時，使給水停止(例如關閉第1電磁閥與第3電磁閥)。開始旋轉給水工程當經過預定時間時結束旋轉給水工程進入步驟S7。 Further, when the water level of the washing water in the outer tub 2 rises to a predetermined water level, the water supply is stopped (for example, the first electromagnetic valve and the third electromagnetic valve are closed). When the rotation of the water supply project is started, the rotation of the water supply project is terminated when the predetermined time elapses, and the process proceeds to step S7.

在步驟S7，控制裝置38是執行預先洗衣攪拌工程(第1攪拌工程)。於此，預先洗衣攪拌工程是指：讓在洗劑溶解工程所生成的洗劑濃度高的洗衣水滲入到衣類的工程。藉由讓洗劑濃度高的洗衣水大量滲入到衣類，可提昇洗淨力。 In step S7, the control device 38 executes the pre-washing agitation process (first agitation process). Here, the pre-washing and stirring process refers to a process in which the washing water having a high concentration of the lotion generated by the lotion dissolution process is infiltrated into the clothes. The washing power can be improved by allowing a large amount of washing water having a high concentration of the lotion to penetrate into the clothes.

具體而言，控制裝置38，是控制使循環泵24成為預定的旋轉數(例如3000rpm)(參照圖10)，而將從排水口21所吸入的清洗水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部。同時，控制馬達4讓滾筒3以預定的旋轉數(例如80rpm)(參照圖10)進行旋轉，藉此，可防止因離心力使滾筒3的內部的衣類貼在滾筒外周壁內面，而施加當其從滾筒的上方落下時所產生的機械性的力的情況。又，在外槽2的圓筒面(例如由前觀看的外槽2 的右側的圓筒面)具備異常溢水用的溢水口(未圖示)時，可期望防止滾筒3由前觀看進行右旋轉(正旋轉)而使清洗水由異常溢水用的排水口(未圖示)流出的情況。在本實施形態，雖讓滾筒3進行正旋轉，可是也可由前觀看使其進行左旋轉(逆旋轉)或在正反兩方向進行旋轉。當經過預定的時間(例如3分鐘)時，控制裝置38結束預先洗衣攪拌工程進到步驟S8。 Specifically, the control device 38 controls the circulation pump 24 to have a predetermined number of rotations (for example, 3000 rpm) (see FIG. 10 ), and the washing water sucked from the drain port 21 is provided from the opening of the outer tank 2 . The nozzle 27a is discharged to the inside of the drum 3. At the same time, the control motor 4 rotates the drum 3 at a predetermined number of rotations (for example, 80 rpm) (refer to FIG. 10), whereby the inner garment of the drum 3 is prevented from being attached to the inner surface of the outer peripheral wall of the drum due to the centrifugal force, and is applied. The condition of the mechanical force generated when it falls from above the drum. Also, on the cylindrical surface of the outer tank 2 (for example, the outer tank 2 viewed from the front) When the cylinder surface on the right side of the cylinder is provided with an overflow port (not shown) for abnormal overflow, it is desirable to prevent the drum 3 from rotating rightward (positive rotation) from the front view and causing the washing water to overflow from the abnormal overflow (not shown). Show) the situation of outflow. In the present embodiment, although the drum 3 is rotated positively, it may be rotated leftward (reverse rotation) or rotated in both forward and reverse directions as viewed from the front. When a predetermined time (for example, 3 minutes) elapses, the control device 38 ends the pre-washing agitation process and proceeds to step S8.

在步驟S8，控制裝置38是執行正式洗衣攪拌工程(第2攪拌工程)。於此，正式洗衣工程是指：藉由滾筒3的旋轉掀起積存在滾筒3內的下方的衣類，藉由讓其從滾筒3內的上方落下，對衣類賦予機械性的力來進行拍打洗衣的工程。 At step S8, the control device 38 performs a formal laundry agitation process (second agitating process). Here, the official laundry process means that the clothes accumulated under the drum 3 are picked up by the rotation of the drum 3, and are dropped from the upper side of the drum 3, thereby imparting mechanical force to the clothes to perform the laundry. engineering.

具體而言，控制裝置38，是控制使循環泵24成為預定的旋轉數(例如3800rpm)(參照圖10)，而將從排水口21所吸入的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，並且，控制馬達4讓滾筒3以預定的旋轉數(例如40rpm)(參照圖10)進行旋轉，藉此對滾筒3的內部的衣類進行拍打洗衣。當經過預定的時間(例如6分鐘)時，控制裝置38結束正式洗衣攪拌工程進到步驟S9。 Specifically, the control device 38 controls the circulation pump 24 to have a predetermined number of rotations (for example, 3,800 rpm) (see FIG. 10 ), and the washing water sucked from the drain port 21 is provided from the opening of the outer tub 2 . The nozzle 27a is discharged to the inside of the drum 3, and the control motor 4 rotates the drum 3 at a predetermined number of rotations (for example, 40 rpm) (refer to FIG. 10), whereby the clothes inside the drum 3 are tapped and washed. When a predetermined time (for example, 6 minutes) elapses, the control device 38 ends the formal laundry agitation work to step S9.

在步驟S9，控制裝置38是執行排水工程。控制裝置38令馬達4及循環泵24停止，打開排水閥25進行外槽2內的洗滌水的排水。水位感應器持續監視排水中的外槽2內的洗滌水的水位。當水位感應器的感測值在預 定的水位以下時，控制裝置38結束排水工程進到步驟S10。 At step S9, the control device 38 performs a drainage project. The control device 38 stops the motor 4 and the circulation pump 24, and opens the drain valve 25 to drain the washing water in the outer tub 2. The water level sensor continuously monitors the water level of the wash water in the outer tank 2 in the drain. When the sensing value of the water level sensor is in advance When the predetermined water level is below, the control device 38 ends the drainage work and proceeds to step S10.

在步驟S10，控制裝置38是執行脫水1工程。控制裝置38，是維持著排水閥25的開閥的狀態下，讓滾筒3以高速進行逆旋轉(例如1250rpm)(圖10)，進行衣類所含有的洗滌水的脫水。當經過預定的時間時，控制裝置38結束脫水1工程進到步驟11。 At step S10, the control device 38 executes the dehydration 1 project. In the control device 38, the drum 3 is reversely rotated at a high speed (for example, 1250 rpm) while maintaining the valve opening of the drain valve 25 (FIG. 10), and the washing water contained in the clothes is dehydrated. When the predetermined time elapses, the control device 38 ends the dehydration 1 project and proceeds to step 11.

在步驟S11，控制裝置38是執行旋轉淋水工程。控制裝置38，既讓滾筒3以中速度進行逆旋轉(例如260rpm)(圖10)，並關閉排水閥25，控制給水電磁閥16(例如打開第3電磁閥)(圖10)將水散佈到衣類。此時的給水電磁閥16的控制時間，是依據在步驟S2所檢出的布量所決定。經過預定的時間時，使給水停止(例如關閉第3電磁閥)。控制使循環泵24成為預定的旋轉數(例如3800rpm)(圖10)，而將從排水口21所吸入的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，來稀釋衣類所含有的洗劑。經過預定的時間時讓循環泵24停止，打開排水閥25進行外槽2內的洗清水的排水。 At step S11, the control device 38 performs a spin-watering project. The control device 38 allows the drum 3 to be reversely rotated at a medium speed (for example, 260 rpm) (Fig. 10), and closes the drain valve 25, and controls the feed water solenoid valve 16 (for example, opens the third solenoid valve) (Fig. 10) to spread the water to Clothing category. The control time of the water supply solenoid valve 16 at this time is determined based on the amount of cloth detected in step S2. When the predetermined time has elapsed, the feed water is stopped (for example, the third solenoid valve is closed). The circulation pump 24 is controlled to have a predetermined number of rotations (for example, 3,800 rpm) ( FIG. 10 ), and the washing water sucked from the drain port 21 is discharged from the nozzle 27 a provided in the opening of the outer tub 2 to the inside of the drum 3 .

In the control device 38, the drum 3 is reversely rotated at a high speed (for example, 1250 rpm) while maintaining the valve opening of the drain valve 25 (FIG. 10), and the washing water contained in the clothes is dehydrated. When the predetermined time elapses, the control device 38 ends the dehydration 2 project and proceeds to step 13.

在步驟S13，控制裝置38是執行給水工程。 控制裝置38，是關閉排水閥25，控制給水電磁閥16(例如打開第1電磁閥)(圖10)將洗清水供給到外槽2內。控制裝置38，是當水位上升到預定的水位時，令給水停止(例如關閉第1電磁閥)，並結束給水工程進到步驟S14。 At step S13, the control device 38 executes the water supply project. The control device 38 closes the drain valve 25, and controls the water supply solenoid valve 16 (for example, opens the first solenoid valve) (Fig. 10) to supply the washing water into the outer tub 2. The control device 38 stops the feed water when the water level rises to a predetermined water level (for example, closes the first electromagnetic valve), and ends the water supply project to step S14.

在步驟S14，控制裝置38是執行柔軟劑給水工程。控制裝置38，是控制給水電磁閥16(例如打開第2電磁閥)，在外槽2內供給含有柔軟劑的洗清水，並且，讓滾筒3朝正反兩方向旋轉攪拌，在步驟S13讓被供給到外槽2內的洗清水與柔軟劑混合。 At step S14, the control device 38 executes the softener water supply project. The control device 38 controls the water supply solenoid valve 16 (for example, opens the second electromagnetic valve), supplies the washing water containing the softening agent in the outer tub 2, and rotates the drum 3 in both the forward and reverse directions, and supplies it in step S13. The washing water to the outer tank 2 is mixed with a softener.

在步驟S15，控制裝置38是執行旋轉給水‧補給水工程。控制裝置38，是控制給水電磁閥16(例如打開第1電磁閥與第3電磁閥)，對外槽2給水到預定的水位為止。又，控制裝置38，是控制馬達4讓滾筒3旋轉，並控制循環泵24形成預定的流量(例如3000rpm)(參照圖10)，而將從排水口21所吸入的洗清水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，讓柔軟劑滲入到衣類。 At step S15, the control device 38 executes the rotary feed water ‧ make-up water project. The control device 38 controls the water supply solenoid valve 16 (for example, opens the first electromagnetic valve and the third electromagnetic valve), and supplies the outer tank 2 to a predetermined water level. Further, the control device 38 controls the motor 4 to rotate the drum 3, and controls the circulation pump 24 to form a predetermined flow rate (for example, 3000 rpm) (see FIG. 10), and the washing water sucked from the drain port 21 is provided in the outer tank. The nozzle 27a of the opening of the 2 is discharged into the inside of the drum 3, and the softener is allowed to permeate into the clothes.

在步驟S16，控制裝置38是執行攪拌工程。控制裝置38，是控制馬達4讓滾筒3旋轉，並控制循環泵24成為預定的流量(例如3800rpm)(參照圖10)，而將從排水口21所吸入的洗清水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，對衣類進行洗清。然後，當經過預定的時間時，控制裝置38結束攪拌工程進到步驟S17。 At step S16, the control device 38 performs the stirring process. The control device 38 controls the motor 4 to rotate the drum 3, and controls the circulation pump 24 to have a predetermined flow rate (for example, 3800 rpm) (see FIG. 10), and the washing water sucked from the drain port 21 is provided from the outer tank 2. The nozzle 27a of the opening is discharged into the inside of the drum 3, and the clothes are washed. Then, when a predetermined time elapses, the control device 38 ends the stirring process and proceeds to step S17.

在步驟S17，控制裝置38是執行排水工程。控制裝置38令馬達4及循環泵24停止，打開排水閥25進行外槽2內的洗清水的排水。水位感應器持續監視排水中的外槽2內的洗滌水的水位。控制裝置38，是當水位感應器的感測值在預定的水位以下時，結束排水工程進到步驟S18。 At step S17, the control device 38 performs a drainage project. The control device 38 stops the motor 4 and the circulation pump 24, and opens the drain valve 25 to drain the washing water in the outer tub 2. The water level sensor continuously monitors the water level of the wash water in the outer tank 2 in the drain. The control device 38 terminates the drainage process to step S18 when the sensed value of the water level sensor is below a predetermined water level.

在步驟S18，控制裝置38是執行脫水工程(脫水工程)。具體而言，控制裝置38，讓排水閥25開閥的同時，控制馬達4讓滾筒3以高速進行逆旋轉，來進行衣類的離心脫水。然後，當經過預定的時間時，控制裝置38令馬達4停止，並關閉排水閥25，結束洗滌行程(洗衣~洗清~脫水)。 At step S18, the control device 38 performs a dehydration process (dehydration process). Specifically, the control device 38 controls the motor 4 to rotate the drum 3 at a high speed while the valve 30 is opened, thereby performing centrifugal dewatering of the clothes. Then, when a predetermined time elapses, the control device 38 stops the motor 4, closes the drain valve 25, and ends the washing course (laundry-washing-dehydration).

正式洗衣攪拌工程(第2攪拌工程)的滾筒3的旋轉數成為未滿60rpm。藉由將滾筒3的旋轉數控制在未滿60rpm，進行掀起積在滾筒3內的下方的衣類，使其從滾筒3內的上方落下的拍打洗衣。在拍打洗衣藉由施加在衣類的落下衝擊(機械力)獲得洗淨性能。又，預先洗衣攪拌工程(第1攪拌工程)的滾筒3的旋轉數成為60rpm以上。藉由使滾筒3的旋轉數成為60rpm以上，滾筒3內的衣類因離心力而貼在滾筒3的壁面方向。亦即，抑制衣類從滾筒3內的上方落下時所施加的落下衝擊(機械力)，可抑制「衣類的粗糙」。一般滾筒式洗衣機，為了進行讓衣類落下的拍打洗衣，而與縱型洗衣機相比衣類容易粗糙，可是根據本實施形態，能抑制預先洗衣攪拌工程中的落下 衝擊而使衣類不易變的粗糙。 The number of rotations of the drum 3 in the official laundry mixing process (second stirring process) was less than 60 rpm. By controlling the number of rotations of the drum 3 to less than 60 rpm, the clothes that are piled up under the drum 3 are smashed and washed from above in the drum 3. The washing performance is obtained by tapping the laundry by applying a drop impact (mechanical force) applied to the clothes. Moreover, the number of rotations of the drum 3 in the pre-washing and stirring process (the first agitation process) is 60 rpm or more. When the number of rotations of the drum 3 is 60 rpm or more, the clothes in the drum 3 are attached to the wall surface direction of the drum 3 by centrifugal force. In other words, it is possible to suppress the "roughness of the clothes" by suppressing the drop impact (mechanical force) applied when the clothes are dropped from the upper side in the drum 3. In general, the drum type washing machine is more likely to be rougher than the vertical type washing machine in order to perform the tapping laundry in which the clothes are dropped. However, according to the embodiment, it is possible to suppress the fall in the pre-washing and stirring process. The impact makes the clothing less likely to become rough.

另一方面，藉由抑制機械力，會有洗淨性能下降的虞慮。而相對於此，預先洗衣攪拌工程(第1攪拌工程)的循環泵24的旋轉數成為2300rpm以上，循環流量變的比以往的滾筒式洗衣機更多。藉此，可讓洗劑濃度高的洗衣水充分滲入衣類，且利用洗劑所含有的界面活性劑、輔助劑等的作用污垢容易從衣類掉落。再者，滾筒3是以60rpm以上的旋轉數進行旋轉，且雖利用離心力將衣類推到滾筒外周壁內面，可是滲入衣類的洗衣水因離心力通過衣類。此時的污垢的一部分因洗衣水通過衣類時的流體力從衣類被去除。如此，在預先洗衣攪拌工程，洗劑濃度高的洗衣水充分滲透到衣類，且因為離心力所為的流體力作用，所以即使縮短正式洗衣攪拌工程的時間(即使縮小機械力)也可確保洗淨性能。此外，也可將滾筒3的旋轉數設成可變，例如60~100rpm。這樣的設定，利用離心力將衣類推壓到滾筒外周壁內面的力改變，而可藉由擠壓洗衣的效果進一步使洗淨力提昇。 On the other hand, by suppressing the mechanical force, there is a concern that the cleaning performance is lowered. On the other hand, the number of rotations of the circulation pump 24 in the pre-washing and stirring process (the first agitation process) is 2,300 rpm or more, and the circulation flow rate is more than that of the conventional drum type washing machine. Thereby, the washing water having a high lotion concentration can be sufficiently infiltrated into the clothes, and the dirt which acts on the surfactant and the auxiliary agent contained in the lotion can be easily dropped from the clothes. Further, the drum 3 is rotated at a number of revolutions of 60 rpm or more, and the laundry is pushed to the inner surface of the outer peripheral wall of the drum by centrifugal force, but the washing water permeating the clothes passes through the clothes due to the centrifugal force. A part of the dirt at this time is removed from the clothes by the fluid force when the washing water passes through the clothes. In this way, in the pre-washing and stirring process, the washing water having a high lotion concentration is sufficiently infiltrated into the clothes, and because of the fluid force acting by the centrifugal force, the cleaning performance can be ensured even if the time of the official laundry mixing process is shortened (even if the mechanical force is reduced). . Further, the number of rotations of the drum 3 may be set to be variable, for example, 60 to 100 rpm. With such a setting, the force of pushing the clothes to the inner surface of the outer peripheral wall of the drum by centrifugal force is changed, and the washing power can be further improved by the effect of squeezing the laundry.

於此，使用圖11針對循環泵24的流量(循環流量)、與洗淨性能的關係進行說明。圖11(a)表示循環泵24的循環流量與洗淨比(洗淨性能)的關係的圖表，圖11(b)表示循環泵24的旋轉數與循環流量的關係的圖表。而且，洗淨比是指試驗洗衣機的洗淨度與標準洗衣機的洗淨度的比，且是被日本工業規格『家庭用電器洗衣機的性能測定方法(JISC9811)』所規定。亦即，洗淨比愈高， 洗淨性能愈高。 Here, the relationship between the flow rate (circulation flow rate) of the circulation pump 24 and the cleaning performance will be described with reference to FIG. 11 . Fig. 11(a) is a graph showing the relationship between the circulation flow rate of the circulation pump 24 and the washing ratio (washing performance), and Fig. 11(b) is a graph showing the relationship between the number of revolutions of the circulation pump 24 and the circulation flow rate. In addition, the washing ratio is a ratio of the washing degree of the test washing machine to the washing degree of the standard washing machine, and is defined by the Japanese Industrial Standard "Measurement Method for Performance of Household Electric Washing Machines (JISC9811)". That is, the higher the cleaning ratio, The higher the cleaning performance.

圖11(a)由實線所示的圖表，是表示本實施形態的滾筒式洗衣乾衣機S所使用的循環泵24的流量與洗淨比的關係的圖表，圖11(a)的虛線，是表示以往的滾筒式洗衣乾衣機的運轉工程的洗淨比的值(洗淨比=1.11)。兩者的洗滌時間相同。 Fig. 11 (a) is a graph showing the relationship between the flow rate of the circulation pump 24 used in the drum-type washer-dryer S of the present embodiment and the washing ratio, and the dotted line of Fig. 11 (a). It is the value (washing ratio=1.11) which shows the washing ratio of the operation of the conventional drum type washer-dryer. Both wash times are the same.

又，圖11(b)由實線所示的圖表，是表示本實施形態的滾筒式洗衣乾衣機S所使用的循環泵24的旋轉數與循環流量的關係的圖表，圖11(b)的虛線，是表示以往的滾筒式洗衣乾衣機所使用的循環泵24的旋轉數與循環流量的關係的圖表。如圖11(b)所示，本實施形態的滾筒式洗衣乾衣機S所使用的循環泵24，是使用循環流量的最大值大的循環泵。 In addition, FIG. 11(b) is a graph showing the relationship between the number of revolutions of the circulation pump 24 used in the drum-type washer-dryer S of the present embodiment and the circulation flow rate, and FIG. 11(b) is a graph showing a solid line. The dotted line is a graph showing the relationship between the number of revolutions of the circulation pump 24 used in the conventional drum type washer-dryer and the circulation flow rate. As shown in Fig. 11 (b), the circulation pump 24 used in the drum-type washer-dryer S of the present embodiment is a circulation pump having a maximum maximum circulation flow rate.

如圖11(a)所示，循環流量愈多洗淨比提昇。可是，洗淨比的上升在循環流量60L/min附近飽和。又，循環流量在約35L/min時與以往的滾筒式洗衣機成為同等的洗淨比。 As shown in Fig. 11(a), the more the circulating flow rate is, the higher the washing ratio is. However, the increase in the washing ratio is saturated near the circulating flow rate of 60 L/min. Further, when the circulation flow rate is about 35 L/min, the washing ratio is equivalent to that of the conventional drum type washing machine.

因此，循環流量是35L/min以上60L/min以下為期望。循環流量比35L/min更少時，洗淨比比以往的滾筒式洗衣機更下降而不理想。又，即使使循環流量比60L/min更多，雖然洗淨比的上升些微，可是由於循環泵24的消耗電力大增，所以增加必要以上地循環流量並不理想。以上，雖以循環流量作為說明，可是在本實施形態例的循環泵24參照圖11(b)時，循環泵的旋轉數成為 2300rpm以上3800rpm以下。 Therefore, it is desirable that the circulation flow rate is 35 L/min or more and 60 L/min or less. When the circulation flow rate is less than 35 L/min, the washing ratio is lower than that of the conventional drum type washing machine. Further, even if the circulation flow rate is more than 60 L/min, the increase in the washing ratio is slightly small, but since the power consumption of the circulation pump 24 is greatly increased, it is not preferable to increase the circulating flow rate more than necessary. In the above, the circulation flow rate is described as follows. However, when the circulation pump 24 of the present embodiment is referred to FIG. 11(b), the number of rotations of the circulation pump becomes 2300 rpm or more and 3800 rpm or less.

此外，循環泵旋轉數在各步驟也可不是經常一定，前述所謂2300rpm以上3800rpm以下的循環泵旋轉數的範圍，是指各步驟的循環泵旋轉數的平均值包含在該範圍內。例如，在步驟S7的預先洗衣攪拌工程中，即使讓循環泵24的旋轉數在2000rpm至3400rpm之間改變，只要平均值在2300rpm以上即可。此外，讓循環泵的旋轉數改變時，從淋灑噴出的洗滌水的散佈範圍改變。因此，可將洗滌水均勻地散佈在衣類。 Further, the number of rotations of the circulation pump may not always be constant in each step, and the range of the number of rotations of the circulation pump of 2,300 rpm or more and 3,800 rpm or less means that the average value of the number of rotations of the circulation pump in each step is included in the range. For example, in the pre-washing agitation process of step S7, even if the number of rotations of the circulation pump 24 is changed between 2000 rpm and 3400 rpm, the average value may be 2300 rpm or more. Further, when the number of rotations of the circulation pump is changed, the dispersion range of the washing water sprayed from the shower is changed. Therefore, the wash water can be uniformly dispersed in the clothes.

於此，以作為增加循環泵24的循環流量用的方針來說，有(1)提高循環泵的旋轉數；(2)使循環泵高性能化；(3)使循環泵大容量化(大徑化)；(4)減低循環流路的壓力損失等。 Here, as a guide for increasing the circulation flow rate of the circulation pump 24, (1) increasing the number of rotations of the circulation pump; (2) improving the performance of the circulation pump; (3) increasing the capacity of the circulation pump (large) (10) Reduce the pressure loss of the circulation flow path and the like.

使用表示圖12所示的循環泵的靜壓力-流量特性的圖表說明等。向右下降的曲線，是表示循環泵24的旋轉數(rev1、rev2、rev3)的靜壓力-流量特性。向右上昇的曲線，是洗滌水的循環流路的阻抗損失曲線(主要為壓力損失)。 A graph indicating the static pressure-flow characteristics of the circulation pump shown in Fig. 12 is used. The curve falling to the right is a static pressure-flow characteristic indicating the number of revolutions (rev1, rev2, rev3) of the circulation pump 24. The curve that rises to the right is the impedance loss curve (mainly pressure loss) of the circulation flow path of the wash water.

將以往的滾筒式洗衣乾衣機的循環泵的旋轉數設為曲線rev1，並將循環路徑的阻抗損失曲線1設為曲線的時候，兩曲線的交點A為動作點，且流量成為Q1，靜壓力成為P1。於此，循環流路與循環泵的旋轉數為了在該狀態增加循環流量，將循環泵的葉輪46形成大徑化時，例如成為由一點鏈線所示的流量-靜壓特性，動作點 移到A’流量增加到Q1’。然而，將葉輪46形成大徑化時，因為循環泵成大型化，所以實際安裝到滾筒式洗衣乾衣機上更加需要空間，滾筒式洗衣乾衣機的筐體也大型化，進而對家庭的設置性變差。 When the number of rotations of the circulation pump of the conventional drum type washer-dryer is set to the curve rev1, and the impedance loss curve 1 of the circulation path is set as a curve, the intersection point A of the two curves is the operation point, and the flow rate becomes Q1, and the flow rate is The pressure becomes P1. In order to increase the circulation flow rate in this state and increase the diameter of the impeller 46 of the circulation pump, the flow rate and the static pressure characteristic indicated by the one-point chain line, the operating point, Move to A' traffic increases to Q1'. However, when the impeller 46 is formed to have a large diameter, since the circulation pump is increased in size, it is more space to be actually mounted on the drum type washer-dryer, and the housing of the drum type washer-dryer is also enlarged, and thus the family The setability is worse.

又，使循環泵24高性能化(提昇效率。具體而言，泵葉輪的形狀最佳化、縮小泵葉輪46與泵殼套42的間隙等)時，例如成為由兩點鏈線所示的流量-靜壓特性，動作點可成為A’，且流量可成為Q1’。可是，在滾筒式洗衣機使用的循環泵24，是在洗滌水(循環水)中含有線屑，設成以效率為優先的泵的時候，因為線屑塞到泵內的可能性增大，所以高性能化有限。 Further, when the circulation pump 24 is improved in performance (elevation efficiency, specifically, the shape of the pump impeller is optimized, and the gap between the pump impeller 46 and the pump casing 42 is reduced), for example, it is represented by a two-dot chain line. Flow-static pressure characteristics, the operating point can be A', and the flow rate can be Q1'. However, in the circulation pump 24 used in the drum type washing machine, when the washing water (circulating water) contains the swarf and is set as the pump with priority in efficiency, since the possibility that the swarf is inserted into the pump increases, High performance is limited.

接著，循環流路與循環泵24為了在該狀態增加循環流量，而將循環泵24的旋轉數提昇到曲線rev2時，動作點成為B，流量成為Q2，靜壓力成為P2。此時，因為靜壓力上昇，所以必須讓循環流路27、蛇腹管41的耐壓力性提昇，而循環流路在該狀態實現困難。又，為了使旋轉數上昇，也會有所謂循環泵24的噪音上昇的問題。因此，僅利用旋轉數提昇循環流量並不理想。 Next, in order to increase the circulation flow rate in this state and increase the number of rotations of the circulation pump 24 to the curve rev2, the circulation flow path and the circulation pump 24 become B, the flow rate becomes Q2, and the static pressure becomes P2. At this time, since the static pressure rises, it is necessary to increase the pressure resistance of the circulation flow path 27 and the bellows 41, and the circulation flow path is difficult in this state. Further, in order to increase the number of rotations, there is a problem that the noise of the circulation pump 24 rises. Therefore, it is not desirable to use only the number of revolutions to increase the circulating flow.

於此，在本實施形態，加大循環路徑的流路面積減低循環路徑的壓力損失，將循環路徑的阻抗損失設為由虛線所示的阻抗損失曲線2的曲線，而使靜壓力成為與以往大致相同的P1。此時的循環泵24的旋轉數為曲線rev3，動作點成為C。藉此，不需要如以往地變更循環路徑的耐壓力性。具體而言，將循環流路27的剖面積以圓 形換算成為直徑25mm以上(剖面積491mm2以上)。又，在入口埠23a的剖面積小的狀態下欲使流量增加時，不僅壓力損失的增加，且吸入埠43的壓力下降空腔作用發生而使噪音急增。因此，雖然吸入埠43的剖面積愈大愈好，可是因為太大時泵性能會下降，所以將循環泵24的吸入埠43的內徑設為35mm。 Here, in the present embodiment, the flow path area of the circulation path is increased to reduce the pressure loss of the circulation path, and the impedance loss of the circulation path is set to the curve of the impedance loss curve 2 indicated by the broken line, and the static pressure is made conventional. Roughly the same P1. The number of rotations of the circulation pump 24 at this time is the curve rev3, and the operating point is C. Thereby, it is not necessary to change the pressure resistance of the circulation path as in the related art. Specifically, the cross-sectional area of the circulation flow path 27 is converted into a diameter of 25 mm or more (sectional area: 491 mm 2 or more) in a circular shape. Further, when the flow rate is increased in a state where the cross-sectional area of the inlet weir 23a is small, not only the pressure loss is increased, but also the pressure of the suction weir 43 is lowered, and the cavity action is caused to increase the noise. Therefore, although the sectional area of the suction port 43 is as large as possible, the pump performance is lowered when the pump performance is too large, so the inner diameter of the suction port 43 of the circulation pump 24 is set to 35 mm.

圖12(b)表示吸入埠43的內徑(d2)與泵葉輪的直徑(d1)的比和循環泵24的流量的關係的圖。流量雖隨著入口埠23a的內徑變大而增加，可是將內徑做的太大時流量轉成下降。這是如由圖6的箭頭印F1所示，因為會發生在循環泵24的葉輪46被吐出的水的一部分再次回到吸入側的循環流。在本實施形態的循環泵，由於d2/d1在0.7至0.8流量成為最大，所以相對於葉輪徑45mm，將吸入埠43的內徑d2設為35mm(以往為22.5mm)。又，上述的最大循環流量60L/min時，d2/d1在0.6以下(d2在27mm以下)空腔作用產生。因此，吸入埠43雖內徑必須27mm以上(剖面積573mm2以上)，然而視情況內徑設為30mm以上(剖面積707mm2以上)為理想。此外，吸入埠43不限於圓形者。於此，比起吸入埠43上游側流路，亦即，入水埠23a、蛇腹管22以及接頭21a當然至少必須為吸入埠43的的剖面積以上。在本實施形態，將吸入埠43的內徑設為35mm(剖面積962mm2)，將上游側流路的最小內徑設為40mm(剖面積1257mm2)。 Fig. 12(b) is a view showing the relationship between the ratio of the inner diameter (d2) of the suction port 43 to the diameter (d1) of the pump impeller and the flow rate of the circulation pump 24. Although the flow rate increases as the inner diameter of the inlet weir 23a becomes larger, the flow rate is decreased when the inner diameter is too large. This is as indicated by the arrow print F1 of Fig. 6, because a part of the water discharged from the impeller 46 of the circulation pump 24 returns to the suction side. In the circulation pump of the present embodiment, since d2/d1 is maximized at a flow rate of 0.7 to 0.8, the inner diameter d2 of the suction weir 43 is 35 mm (previously 22.5 mm) with respect to the impeller diameter of 45 mm. Further, when the maximum circulation flow rate described above is 60 L/min, d2/d1 is generated in a cavity of 0.6 or less (d2 is 27 mm or less). Therefore, the inner diameter of the suction port 43 is required to be 27 mm or more (the cross-sectional area is 573 mm 2 or more), but it is preferable that the inner diameter is 30 mm or more (the cross-sectional area is 707 mm 2 or more). Further, the inhalation crucible 43 is not limited to a circular one. Here, the inlet port 23a, the bellows tube 22, and the joint 21a need to be at least the cross-sectional area of the suction port 43 at least in comparison with the upstream side flow path of the suction port 43. In the present embodiment, the inner diameter of the suction port 43 is 35 mm (sectional area: 962 mm 2 ), and the minimum inner diameter of the upstream side flow path is 40 mm (sectional area: 1257 mm 2 ).

根據以上，在本實施形態，是將讓水流入收 納循環泵24的葉輪46的殼套42內的吸入埠43的剖面積設成707mm2以上，將該吸入埠43進行圓形換算時的直徑(d2)與泵葉輪的直徑(d1)的比的d2/d1設在0.66以上0.8以下，並且將吸入埠43的上游側流路的剖面積設為吸入埠43的剖面積以上，將外槽2的底部至上部的循環流路27的剖面積設為491mm2以上時，將循環泵24的旋轉數設在2300rpm以上3800rpm以下。藉此，既維持循環泵24的實際安裝性、低噪音等，亦可實現35L/min以上的高的循環流量，使洗淨性能提昇。 As described above, in the present embodiment, the cross-sectional area of the suction weir 43 that allows water to flow into the casing 42 of the impeller 46 that houses the circulation pump 24 is 707 mm 2 or more, and the diameter of the suction weir 43 is circularly converted. (d2) d2/d1 of the ratio of the diameter (d1) of the pump impeller is set to 0.66 or more and 0.8 or less, and the cross-sectional area of the upstream side flow path of the suction weir 43 is set to be larger than the sectional area of the suction weir 43 and the outer groove When the cross-sectional area of the circulation flow path 27 from the bottom to the upper portion of 2 is 491 mm 2 or more, the number of rotations of the circulation pump 24 is set to 2,300 rpm or more and 3,800 rpm or less. Thereby, the actual installation performance of the circulation pump 24, low noise, and the like are maintained, and a high circulation flow rate of 35 L/min or more can be achieved, and the washing performance can be improved.

從噴嘴27a被吐出到滾筒3內的洗滌水，是通過滾筒3內的衣類內、衣類間的間隙，通過設在滾筒3的外周壁的貫穿孔流出到外槽2內回到凹陷部2f，而再次被吸入到循環泵24。此時，在凹陷部2F沒有足夠的水的時候，空氣被吸入循環泵24，而使洗滌水的循環變的困難。因此，在本實施形態，加大凹陷部2f的容積，來確保被吸入的循環水。 The washing water discharged from the nozzle 27a into the drum 3 passes through the gap between the clothing and the clothing in the drum 3, and flows out into the outer tank 2 through the through hole provided in the outer peripheral wall of the drum 3, and returns to the recessed portion 2f. It is again sucked into the circulation pump 24. At this time, when there is not enough water in the recessed portion 2F, the air is sucked into the circulation pump 24, making it difficult to circulate the washing water. Therefore, in the present embodiment, the volume of the recessed portion 2f is increased to secure the circulating water that is sucked.

又，衣類的量愈多，衣類保持的水量增加，從噴嘴27a出來到返回凹陷部2f的時間變長。為了確保穩定的循環流量，所以衣類的量愈多就必須增加使用水量。可是，在洗衣、洗清等的工程中，藉由暫時停止按鈕操作等使滾筒3的旋轉、循環泵24的旋轉停止時，衣類所含有的洗滌水因重力脫離而使外槽2的水位上昇。雖然循環流量愈多水位的上昇愈大，可是循環流量太多時因為會從異常溢水口被排水，所以洗滌水會白白被消耗掉。因 此，也可設成衣類的量愈多循環流量變少。 Further, the more the amount of the clothes, the more the amount of water held by the clothes increases, and the time from the nozzle 27a to the returning recess 2f becomes longer. In order to ensure a stable circulating flow rate, the more the amount of clothing, the more the amount of water used must be used. However, when the rotation of the drum 3 or the rotation of the circulation pump 24 is stopped by the temporary stop button operation or the like in the process of washing, washing, etc., the washing water contained in the clothes is detached by gravity, and the water level of the outer tub 2 rises. . Although the more the circulating flow rate, the higher the water level rises, the circulating water will be drained from the abnormal overflow because the circulating flow will be too much. because Therefore, it is also possible to set the amount of the garments to be smaller as the circulation flow rate is reduced.

衣類的量多的時候，在滾筒3的旋轉掀起衣類使其落下時，因為其他的衣類的重量所為的作用大，拍打洗衣效果充分地作用，所以即使多少減少循環流量也可確保洗淨力。另一方面，因為衣類的量少的時候，其他的衣類的重量所為的效果變少，所以通常洗淨力雖會下降，可是增加循環流量讓衣類充分含水，可提高拍打洗衣效果並抑制洗淨力的下降。 When the amount of the clothes is large, when the drum 3 is rotated and the clothes are dropped, the weight of the other clothes is large, and the washing effect is sufficiently exerted. Therefore, the washing power can be ensured even if the circulation flow rate is somewhat reduced. On the other hand, when the amount of clothing is small, the weight of other clothes is less, so the washing power is usually lowered, but the circulation flow rate is increased to make the clothes sufficiently hydrated, and the washing effect can be improved and the washing can be suppressed. The decline in force.

此外，在第1實施形態，雖是形成在第1攪拌工程讓衣類壁黏貼，在第2攪拌工程讓機械力作動的運轉，可是也可在第1攪拌工程讓機械力作動，在第2攪拌工程讓衣類黏著的運轉。 In addition, in the first embodiment, the first agitating work is performed on the wall of the clothes, and the mechanical operation is performed in the second agitation process. However, the mechanical force may be actuated in the first agitation process, and the second agitation may be performed. The project allowed the clothes to stick and work.

如以上，根據第1實施形態的滾筒式洗衣乾衣機S的運轉工程將以往20L/min左右的循環流量大幅提高到35L/min以上60L/min以下，使洗滌水從細縫狀的噴嘴灑水到滾筒內的廣範圍。循環流量增多時，洗淨比提昇的原因，是因為在足夠的洗衣水浸透到利用滾筒3的旋轉被掀起的衣類整體的狀態下衣類落下，所以衣類所含有的洗衣水在落下的衝擊下與污垢一起從衣類被推出(拍打洗衣)。又，循環流量超過60L/min時洗淨比的上昇幾乎飽和，是因為在衣類可含有的水的量是有限度的，即使增加必要以上流量，洗衣水在衣類的外側流對於洗淨並無幫助。又，因為洗滌水浸透衣類整體，所以即使在洗清也可效率佳地進行洗劑成分的稀釋，且洗清性能也可提昇。 As described above, according to the operation of the drum-type washer-dryer S of the first embodiment, the circulating flow rate of about 20 L/min or more is increased to 35 L/min or more and 60 L/min or less, and the washing water is sprinkled from the slit-like nozzle. A wide range of water into the drum. When the circulation flow rate is increased, the reason why the cleaning ratio is increased is that the laundry is soaked in the state in which the entire washing clothes are picked up by the rotation of the drum 3, so that the laundry water contained in the clothes falls under the impact of falling. The dirt is pushed out from the clothing (slap the laundry). Further, when the circulation flow rate exceeds 60 L/min, the increase in the washing ratio is almost saturated because the amount of water that can be contained in the clothes is limited, and even if the flow rate is increased more than necessary, the washing water flows out of the clothes for washing. help. Further, since the washing water is impregnated into the entire clothes, the lotion component can be efficiently diluted even after washing, and the washing performance can be improved.

一般，縱型洗衣機，因為槽的開口部位在上面側，因此利用高的水位所為的蓄積水洗衣來進行洗滌，則粗糙變少。可是，滾筒式洗衣機因為開口部在前面側，所以既要防止漏水又要提高水位是非常困難的。於此，在本實施形態，大幅增加循環流量，讓衣類含有足夠的洗衣水，即使縮短拍打洗衣的時間也可確保洗淨力，結果來說，可減少衣類的粗糙。亦即，不會使滾筒式洗衣機的特徵的節水性能惡化，而可利用高洗淨力實現粗糙少的洗滌。 In general, in a vertical type washing machine, since the opening portion of the groove is on the upper side, the washing is performed by the accumulated water washing by the high water level, and the roughness is reduced. However, since the drum type washing machine has the opening portion on the front side, it is extremely difficult to prevent water leakage and increase the water level. Here, in the present embodiment, the circulation flow rate is greatly increased, and the laundry contains sufficient washing water, and the washing power can be ensured even when the time for washing the laundry is shortened. As a result, the roughness of the clothes can be reduced. That is, the water-saving performance of the features of the drum type washing machine is not deteriorated, and the coarse washing can be achieved with high washing power.

圖13，是針對縱型洗衣機、以往的滾筒式洗衣機、本實施形態的滾筒式洗衣乾衣機，進行5回含有毛巾的試驗布3kg的洗滌運轉，以5階段進行衣類的粗糙的官能評價的試驗的結果。如由該圖可知，相對於以往的滾筒式洗衣機評價值為2，本實施形態的滾筒式洗衣乾衣機的評價值為4.1，而與縱型洗衣機同樣大幅抑制了粗糙。針對毛巾這類絨毛質地的洗滌物，也可實現絨毛質地不會壓潰的立著的狀態的柔軟地完成。 FIG. 13 is a washing operation of a vertical washing machine, a conventional drum type washing machine, and a drum type washing and drying machine of the present embodiment, in which 5 kg of a test cloth containing a towel is carried out, and the rough functional evaluation of the clothes is performed in five stages. The result of the test. As can be seen from the figure, the evaluation value of the drum type washing machine of the present embodiment is 2, and the evaluation value of the drum type washer-dryer of the present embodiment is 4.1, and the roughness is greatly suppressed as in the vertical type washing machine. The laundry of the pile texture such as a towel can be softly completed in a standing state in which the texture of the pile is not crushed.

接著，針對在滾筒式洗衣機容易產生變黑的抑制效果進行說明。變黑，主要是因為從衣類被去除的污垢的一部分再次附著在衣類(再污染現象)所產生的。滾筒式洗衣機和縱型洗衣機相比使用水量少為特徵。可是，衣類的髒污量與洗淨力一起時，因為洗滌水的髒污的濃度是滾筒式洗衣機較高，所以容易變黑。一般來說，滾筒式洗衣機和縱型洗衣機相比使用水量一半左右，髒污的濃度約 成為2倍。且，洗滌時間愈長愈容易變黑。 Next, the effect of suppressing the occurrence of blackening in the drum type washing machine will be described. Blackening is mainly due to the fact that a part of the dirt removed from the clothing is again attached to the clothing (recontamination phenomenon). The drum type washing machine is characterized by a smaller amount of water than a vertical type washing machine. However, when the amount of dirt of the clothes is together with the detergency, since the concentration of the dirty water of the washing water is higher than that of the drum type washing machine, it tends to be black. In general, the drum type washing machine uses about half the amount of water compared to the vertical type washing machine, and the concentration of the dirt is about Become 2 times. Moreover, the longer the washing time, the more likely it becomes black.

根據我們的檢討，將滾筒式洗衣機與縱型洗衣機的洗滌時間設成大致相同時，滾筒式洗衣機在水量的差(洗滌水的髒污濃度的差)以上變黑的情況多。這個可想到的是因為洗衣方式的不同所形成的要因者。縱型洗衣機，是衣類沈在洗滌水中的狀態下進行洗滌，而相對於此，滾筒式洗衣機的洗滌，是利用滾筒的旋轉反覆進行將水中的衣類從水中抬到空中使其落下到水面的狀態下進行洗滌。從衣類被去除的疏水性的污垢容易集中在水面。該污垢，是在衣類離水面進入到水面時再次附著到衣類，而使變黑的情況加深。 According to our review, when the washing time of the drum type washing machine and the vertical type washing machine are set to be substantially the same, the drum type washing machine is often blackened by the difference in the amount of water (the difference in the dirty concentration of the washing water). This is conceivable because of the different factors of the way the laundry is formed. The vertical type washing machine washes in a state where the clothes sink in the washing water, whereas the washing of the drum type washing machine is a state in which the clothes in the water are lifted from the water into the air to fall to the water surface by the rotation of the drum. Wash underneath. The hydrophobic dirt removed from the clothing is easily concentrated on the water surface. The dirt is attached to the clothes again when the clothes enter the water surface from the water surface, and the blackening is deepened.

在本實施形態的滾筒式洗衣機，因為洗滌水的循環流量多，所以對跑到空中的衣類噴吹大量的洗滌水。因而，形成衣類被洗滌水的膜所包覆的狀態下落下到水中，水面的污垢不易再次附著，而具有抑制變黑的效果。再者，如上述，因為也具有提高洗淨力的效果，所以因為縮短了洗衣工程的時間，所以可更進一步抑制變黑。 In the drum type washing machine of the present embodiment, since the circulating flow rate of the washing water is large, a large amount of washing water is sprayed on the clothes that are in the air. Therefore, the state in which the clothing is covered with the film of the washing water falls down to the water, and the dirt on the water surface is less likely to adhere again, and the effect of suppressing blackening is obtained. Further, as described above, since the effect of improving the detergency is also obtained, since the time of the laundry process is shortened, the blackening can be further suppressed.

圖14，是表示循環流量與變黑的關係的實驗結果的一例。實驗，是反覆同時進行附著人工皮脂污垢、碳等的無機質污垢的衣類、與白色衣類的洗滌(布量3kg)。圖14，是洗滌5回後的數據。亮度變化，是白色的衣類的洗滌後的亮度減新品的亮度的值，且值愈大則變黑愈大。如由圖可知，循環流量愈多則亮度變化愈少，且不易變黑。不只洗淨力考慮變黑時，循環流量增加到68 L/min左右(循環泵旋轉數4200rpm)為理想，在本實驗條件可幾乎抑制變黑的產生。 Fig. 14 is an example of experimental results showing the relationship between the circulating flow rate and the blackening. In the experiment, clothes which adhere to inorganic sebum such as artificial sebum dirt and carbon, and white clothes (washing amount: 3 kg) were simultaneously applied. Figure 14 is the data after washing 5 times. The change in brightness is a value of the brightness of the brightness reduction product after washing of the white clothing, and the larger the value, the larger the blackening. As can be seen from the figure, the more the circulating flow rate, the less the brightness changes and the less black. Not only when the cleaning power is considered to be black, the circulation flow rate is increased to 68. It is desirable that L/min or so (the number of circulating pump rotations is 4,200 rpm), and the occurrence of blackening can be almost suppressed under the experimental conditions.

圖15，是洗滌附著與圖14同樣的污垢的衣類時(5回後)的縱型式洗衣機、以往的滾筒式洗衣機、以及本實施形態的滾筒式洗衣乾衣機(將圖10的S8的正式洗衣攪拌與S16的洗清攪拌時的循環泵旋轉數設為4200rpm(循環流量68L/min)時)的變黑(亮度變化)的比較。如由該圖可知，相對於以往的滾筒式洗衣機亮度變化4.5，本實施形態的滾筒式洗衣機的亮度變化成為0.1，可知與縱型洗衣機同樣能大幅抑制變黑。 15 is a vertical type washing machine in which clothes having the same dirt as that of FIG. 14 are attached (after five times), a conventional drum type washing machine, and a drum type washing and drying machine of the present embodiment (the formalization of S8 of FIG. 10) The comparison between the blackening (brightness change) of the number of circulating pump rotations at the time of washing and stirring and S16 washing and stirring was set to 4,200 rpm (circulation flow rate: 68 L/min). As can be seen from the above-mentioned figure, the brightness change of the drum type washing machine of the present embodiment is changed to 4.5, and the change in the brightness of the drum type washing machine of the present embodiment is 0.1, and it is understood that the blackening can be greatly suppressed similarly to the vertical type washing machine.

<<第2實施形態的運轉工程>> <<Operation Engineering of Second Embodiment>>

接著，使用圖16針對第2實施形態的滾筒式洗衣乾衣機S的運轉工程進行說明。圖16是說明第2實施形態的滾筒式洗衣乾衣機S的洗滌運轉(洗衣~洗清~脫水)的運轉工程的工程圖。 Next, the operation of the drum-type washer-dryer S of the second embodiment will be described with reference to Fig. 16 . FIG. 16 is a view showing an operation of the washing operation (laundry to washing-dehydration) of the drum-type washer-dryer S according to the second embodiment.

第1實施形態的滾筒式洗衣乾衣機S的運轉工程(參照圖10)、與第2實施形態的滾筒式洗衣乾衣機S的運轉工程(參照圖16)，是洗衣工程的預先洗衣攪拌到正式洗衣攪拌的工程不同。因為其他的工程(S1~S6、S10~S19)(參照圖16)同樣，所以省略說明。 The operation of the drum-type washer-dryer S of the first embodiment (see FIG. 10) and the operation of the drum-type washer-dryer S of the second embodiment (see FIG. 16) are pre-washing agitation of the laundry project. The work to the official laundry mixing is different. Since the other items (S1 to S6, S10 to S19) (see Fig. 16) are the same, the description is omitted.

在步驟S7，控制裝置38是執行預先洗衣攪拌工程(第1攪拌工程)。於此，預先洗衣攪拌工程是指：讓在洗劑溶解工程所生成的洗劑濃度高的洗衣水滲入到衣類 的工程。藉由讓洗劑濃度高的洗衣水滲入到衣類，使洗淨力提昇。 In step S7, the control device 38 executes the pre-washing agitation process (first agitation process). Here, the pre-washing and stirring process means that the washing water having a high concentration of the lotion generated by the lotion dissolving process is infiltrated into the clothes. Engineering. The washing power is increased by allowing the washing water having a high concentration of the lotion to penetrate into the clothes.

具體而言，控制裝置38，是控制使循環泵24成為預定的旋轉數(例如3000rpm)(參照圖16)，而將從排水口21所吸入的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，並且，控制馬達4讓滾筒3以預定的旋轉數(例如80rpm)(參照圖16)進行旋轉，藉此可防止滾筒3的內部的衣類黏在滾筒外周壁3d內面，從滾筒的上方落下時產生的機械性的力的施加。又，在外槽2的圓筒面(例如外槽2的右側的圓筒面)具備異常溢水用的溢水口(未圖示)時，可防止讓滾筒3進行正旋轉而使洗衣水由異常溢水用的排水口(未圖示)流出的情況為期望。在本實施形態，雖讓滾筒3進行正旋轉，可是也可讓其進行逆旋轉或正反兩方向旋轉。當經過預定的時間(例如3分鐘)時，控制裝置38結束預先洗衣攪拌工程進到步驟S8。 Specifically, the control device 38 controls the circulation pump 24 to have a predetermined number of rotations (for example, 3000 rpm) (see FIG. 16), and the washing water sucked from the drain port 21 is provided from the opening of the outer tank 2. The nozzle 27a is ejected to the inside of the drum 3, and the control motor 4 rotates the drum 3 at a predetermined number of rotations (for example, 80 rpm) (refer to Fig. 16), whereby the clothes of the inside of the drum 3 can be prevented from sticking to the outer peripheral wall 3d of the drum. The inner surface exerts a mechanical force generated when it falls from above the drum. Further, when the cylindrical surface of the outer tub 2 (for example, the cylindrical surface on the right side of the outer tub 2) is provided with a water overflow port (not shown) for abnormal overflow, it is possible to prevent the drum 3 from rotating forward and causing the washing water to overflow abnormally. The case where the drain port (not shown) flows out is desirable. In the present embodiment, although the drum 3 is rotated positively, it may be rotated in the reverse rotation or in both the forward and reverse directions. When a predetermined time (for example, 3 minutes) elapses, the control device 38 ends the pre-washing agitation process and proceeds to step S8.

在步驟S8，控制裝置38，是執行補給水工程。控制裝置38，是控制給水電磁閥(例如打開第1電磁閥與第3電磁閥)，對外槽2內給水。當外槽2內的洗衣水的水位上昇到預定的水位時，使給水停止(例如關閉第1電磁閥與第3電磁閥)，結束補給水工程進入到步驟S9。 At step S8, the control device 38 executes the makeup water project. The control device 38 controls the water supply solenoid valve (for example, opens the first electromagnetic valve and the third electromagnetic valve) to supply water to the outer tank 2. When the water level of the washing water in the outer tub 2 rises to a predetermined water level, the water supply is stopped (for example, the first electromagnetic valve and the third electromagnetic valve are closed), and the makeup water project is terminated, and the flow proceeds to step S9.

在步驟S9，控制裝置38是執行正式洗衣攪拌工程(第2攪拌工程)。於此，正式洗衣工程是指：藉由滾筒3的旋轉掀起積存在滾筒3內的下方的衣類，藉由讓其從滾筒3內的上方落下，對衣類賦予機械性的力來進行拍 打洗衣的工程。 In step S9, the control device 38 performs a formal laundry agitation process (second agitating process). Here, the official laundry process means that the clothes accumulated under the drum 3 are picked up by the rotation of the drum 3, and are dropped from the upper side of the drum 3 to give a mechanical force to the clothes. The work of washing laundry.

具體而言，控制裝置38，是控制使循環泵24成為預定的旋轉數(例如3800rpm)(參照圖16)，而將從排水口21所吸入的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，並且，控制馬達4讓滾筒3以預定的旋轉數(例如40rpm)(參照圖16)進行旋轉，藉此對滾筒3的內部的衣類進行拍打洗衣。當經過預定的時間(例如6分鐘)時，控制裝置38結束正式洗衣攪拌工程。 Specifically, the control device 38 controls the circulation pump 24 to have a predetermined number of rotations (for example, 3800 rpm) (see FIG. 16), and the washing water sucked from the drain port 21 is provided from the opening of the outer tank 2. The nozzle 27a is discharged to the inside of the drum 3, and the motor 4 is controlled to rotate the drum 3 by a predetermined number of rotations (for example, 40 rpm) (refer to FIG. 16), whereby the clothes inside the drum 3 are tapped and washed. When a predetermined time (e.g., 6 minutes) elapses, the control device 38 ends the formal laundry agitation process.

在本實施形態，是在預先洗衣攪拌工程(步驟S7)之後，進行補給水工程(步驟S8)。亦即，在補給水工程之後執行的正式洗衣攪拌工程(步驟S9)的水量，是形成比預先洗衣攪拌工程的水量更多。藉由增加外槽2內的洗衣水的水量，可讓從衣類被剝離的污垢分散到洗衣水，讓洗衣水的污垢的濃度變低，而可抑制從衣類被剝離的污垢再次附著到衣類所產生的「衣類的變黑」。一般滾筒式洗衣機，由於與縱型洗衣機相比外槽2內的洗滌水少，所以衣類的污垢的情況高的時候，變黑容易發生，可是根據本實施形態污垢變薄且變黑變的不易產生。 In the present embodiment, after the pre-washing and stirring process (step S7), the makeup water project is performed (step S8). That is, the amount of water in the formal laundry agitation work (step S9) performed after the make-up water project is more than the amount of water in the pre-washing agitation project. By increasing the amount of the washing water in the outer tank 2, the dirt which is peeled off from the clothes can be dispersed into the washing water, so that the concentration of the dirt of the washing water becomes low, and the dirt which is peeled off from the clothes can be suppressed from being attached to the clothes again. The resulting "blackening of clothing". In general, the drum type washing machine has less washing water in the outer tub 2 than the vertical washing machine. Therefore, when the dirt of the clothing is high, blackening is likely to occur, but according to the embodiment, the dirt becomes thin and black becomes difficult. produce.

正式洗衣攪拌工程(第2攪拌工程)的滾筒3的旋轉數成為未滿60rpm。藉由將滾筒3的旋轉數控制在未滿60rpm，進行掀起積在滾筒3內的下方的衣類，使其從滾筒3內的上方落下的拍打洗衣。藉由利用拍打洗衣施加在衣類的落下衝擊(機械力)會有「衣類的粗糙」惡化的虞慮。而相對於此，在補給水工程(步驟S8)，對外槽2內給 水，使外槽2內的洗衣水的水位上昇，抑制落下衝擊(機械力)，可抑制「衣類的粗糙」。 The number of rotations of the drum 3 in the official laundry mixing process (second stirring process) was less than 60 rpm. By controlling the number of rotations of the drum 3 to less than 60 rpm, the clothes that are piled up under the drum 3 are smashed and washed from above in the drum 3. By using the tapping laundry to apply the falling impact (mechanical force) of the clothing, there is a concern that the "roughness of the clothing" is deteriorated. On the other hand, in the make-up water project (step S8), the outer tank 2 is given The water raises the water level of the washing water in the outer tub 2, and suppresses the drop impact (mechanical force), thereby suppressing "roughness of the clothes".

又，預先洗衣攪拌工程(第1攪拌工程)的滾筒3的旋轉數成為60rpm以上。藉由使滾筒3的旋轉數成為60rpm以上，滾筒3內的衣類因離心力而貼在滾筒3的壁面方向。亦即，抑制衣類從滾筒3內的上方落下時所施加的落下衝擊(機械力)，可抑制「衣類的粗糙」。 Moreover, the number of rotations of the drum 3 in the pre-washing and stirring process (the first agitation process) is 60 rpm or more. When the number of rotations of the drum 3 is 60 rpm or more, the clothes in the drum 3 are attached to the wall surface direction of the drum 3 by centrifugal force. In other words, it is possible to suppress the "roughness of the clothes" by suppressing the drop impact (mechanical force) applied when the clothes are dropped from the upper side in the drum 3.

另一方面，藉由抑制機械力，會有洗淨性能下降的虞慮。而相對於此，因為預先洗衣攪拌工程(第1攪拌工程)的水量比正式洗衣工程的水量更少，所以洗劑濃度高。又，循環泵18的流量成為2300rpm以上，且循環流量多。因此，可讓高的洗劑濃度的洗衣水充分含在衣類，可更進一步容易去掉污垢。藉此，形成可確保洗淨性能。 On the other hand, by suppressing the mechanical force, there is a concern that the cleaning performance is lowered. On the other hand, since the amount of water in the pre-washing and stirring process (the first agitation process) is smaller than the amount of water in the official laundry process, the lotion concentration is high. Further, the flow rate of the circulation pump 18 is 2,300 rpm or more, and the circulation flow rate is large. Therefore, the washing water having a high lotion concentration can be sufficiently contained in the clothes, and the dirt can be further removed more easily. Thereby, formation can ensure cleaning performance.

如以上，根據第2實施形態的滾筒式洗衣乾衣機S的運轉工程，確保洗淨性能並可抑制衣類的變黑與粗糙。 As described above, according to the operation of the drum-type washer-dryer S of the second embodiment, the washing performance is ensured, and the blackening and roughening of the clothes can be suppressed.

<<第3實施形態的運轉工程>> <<Operation Engineering of Third Embodiment>>

Engineering drawings.

第1實施形態的滾筒式洗衣乾衣機S的運轉工程(參照圖10)、與第3實施形態的滾筒式洗衣乾衣機S的運轉工程(參照圖17)，是洗衣工程的旋轉給水工程到洗清2工程的洗清攪拌工程的工程不同。因為其他的工程(S1~S5、S17~S18)(參照圖17)同樣的，所以省略說明。 The operation of the drum-type washer-dryer S of the first embodiment (see FIG. 10) and the operation of the drum-type washer-dryer S of the third embodiment (see FIG. 17) are rotary water supply projects for the laundry project. It is different from the work of the washing and mixing work of the cleaning 2 project. Since the other items (S1 to S5, S17 to S18) (see FIG. 17) are the same, the description is omitted.

在步驟S6，控制裝置38是執行旋轉給水工程(旋轉給水工程)。具體而言，控制裝置38，是控制給水電磁閥16(例如打開第1電磁閥與第3電磁閥)，讓外槽2內的洗衣水的水位上昇，並且控制馬達4讓滾筒3成為預定的旋轉數(例如40rpm)(參照圖17)，來進行衣類的翻轉，並且控制使循環泵24成為預定的旋轉數(例如2300rpm)(參照圖17)，而將從排水口21所吸入的洗劑濃度高的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，藉此滲入到滾筒3的內部的衣類。 At step S6, the control device 38 executes a rotary water supply project (rotary water supply project). Specifically, the control device 38 controls the water supply solenoid valve 16 (for example, opens the first electromagnetic valve and the third electromagnetic valve) to raise the water level of the washing water in the outer tub 2, and controls the motor 4 to make the drum 3 predetermined. The number of rotations (for example, 40 rpm) (refer to FIG. 17) is performed to invert the clothes, and the circulation pump 24 is controlled to have a predetermined number of rotations (for example, 2,300 rpm) (see FIG. 17), and the lotion to be sucked from the drain port 21 is controlled. The washing water having a high concentration is discharged from the nozzle 27a provided in the opening of the outer tub 2 to the inside of the drum 3, thereby infiltrating into the clothes inside the drum 3.

而且，當外槽2內的洗衣水的水位上昇到預定的水位時，使給水停止(例如關閉第1電磁閥與第3電磁閥)。開始旋轉給水工程當經過預定時間時結束旋轉給 水工程進入步驟S7。 Further, when the water level of the washing water in the outer tub 2 rises to a predetermined water level, the water supply is stopped (for example, the first electromagnetic valve and the third electromagnetic valve are closed). Start rotating the water supply project and end the rotation when the predetermined time elapses. The water project proceeds to step S7.

在步驟S7，控制裝置38是執行預先洗衣攪拌工程。於此，預先洗衣攪拌工程是指：讓在洗劑溶解工程所生成的洗劑濃度高的洗衣水滲入到衣類的工程。藉由讓洗劑濃度高的洗衣水滲入到衣類，使洗淨力提昇。 At step S7, the control device 38 executes the pre-washing agitation project. Here, the pre-washing and stirring process refers to a process in which the washing water having a high concentration of the lotion generated by the lotion dissolution process is infiltrated into the clothes. The washing power is increased by allowing the washing water having a high concentration of the lotion to penetrate into the clothes.

具體而言，控制裝置38，是控制使循環泵24成為預定的旋轉數(例如2300rpm)(參照圖17)，而將從排水口21所吸入的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，並且，控制馬達4讓滾筒3以預定的旋轉數(例如40rpm)(參照圖17)進行正反旋轉，藉此讓洗劑濃度高的洗衣水滲入到衣類。當經過預定的時間(例如3分鐘)時，控制裝置38結束預先洗衣攪拌工程進到步驟S8。 Specifically, the control device 38 controls the circulation pump 24 to have a predetermined number of rotations (for example, 2,300 rpm) (see FIG. 17 ), and the washing water sucked from the drain port 21 is provided from the opening of the outer tub 2 . The nozzle 27a is discharged to the inside of the drum 3, and the control motor 4 causes the drum 3 to rotate forward and backward at a predetermined number of rotations (for example, 40 rpm) (refer to FIG. 17), thereby allowing the washing water having a high detergent concentration to permeate into the clothes. When a predetermined time (for example, 3 minutes) elapses, the control device 38 ends the pre-washing agitation process and proceeds to step S8.

在步驟S8，控制裝置38是執行正式洗衣攪拌工程。於此，正式洗衣工程是指：藉由滾筒3的旋轉掀起積存在滾筒3內的下方的衣類，藉由讓其從滾筒3內的上方落下，對衣類賦予機械性的力來進行拍打洗衣的工程。 At step S8, the control device 38 performs a formal laundry agitation project.

The control device 38 stops the motor 4 and the circulation pump 24, and opens the drain valve 25 to drain the washing water in the outer tub 2. The water level sensor continuously monitors the water level of the wash water in the outer tank 2 in the drain. When the sensed value of the water level sensor is below the predetermined water level, the control device 38 ends the drainage work to step S10.

在步驟S10，控制裝置38是執行脫水1工程。控制裝置38，是在維持著排水閥25的開閥的狀態下，讓滾筒3以高速朝逆向進行旋轉(例如1250rpm)(圖17)，進行衣類所含有的洗滌水的脫水。當經過預定的時間時，控制裝置38結束脫水1工程進到步驟11。 At step S10, the control device 38 executes the dehydration 1 project. In the control device 38, the drum 3 is rotated in the reverse direction (for example, 1250 rpm) while maintaining the valve opening of the drain valve 25 (FIG. 17), and the washing water contained in the clothes is dehydrated. When the predetermined time elapses, the control device 38 ends the dehydration 1 project and proceeds to step 11.

The control time of the water supply solenoid valve 16 at this time is determined based on the amount of cloth sensed in step S2. When the predetermined time has elapsed, the feed water is stopped (for example, the third solenoid valve is closed). The circulation pump 24 is controlled to have a predetermined number of rotations (for example, 2,300 rpm) (FIG. 17), and the washing water sucked from the drain port 21 is discharged from the nozzle 27a provided in the opening of the outer tub 2 to the inside of the drum 3.

The washing water to the outer tank 2 is mixed with a softener.

在步驟S15，控制裝置38是執行旋轉給水‧補給水工程。控制裝置38，是控制給水電磁閥16(例如打開第1電磁閥與第3電磁閥)，對外槽2給水到預定的水位為止。又，控制裝置38，是控制馬達4讓滾筒3旋轉，並控制循環泵24形成預定的流量(例如2300rpm)(參照圖17)，而將從排水口21所吸入的洗清水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，讓柔軟劑滲入到衣類。 At step S15, the control device 38 executes the rotary feed water ‧ make-up water project. The control device 38 controls the water supply solenoid valve 16 (for example, opens the first electromagnetic valve and the third electromagnetic valve), and supplies the outer tank 2 to a predetermined water level. Further, the control device 38 controls the motor 4 to rotate the drum 3, and controls the circulation pump 24 to form a predetermined flow rate (for example, 2300 rpm) (see FIG. 17), and the washing water sucked from the drain port 21 is provided in the outer tank. The nozzle 27a of the opening of the 2 is discharged into the inside of the drum 3, and the softener is allowed to permeate into the clothes.

在步驟S16，控制裝置38是執行攪拌工程。控制裝置38，是控制馬達4讓滾筒3旋轉，並控制循環 泵24形成預定的旋轉數(例如2300rpm)(參照圖17)，而將從排水口21所吸入的洗清水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，對衣類進行洗清。然後，當經過預定的時間時，控制裝置38結束攪拌工程。 At step S16, the control device 38 performs the stirring process. The control device 38 controls the motor 4 to rotate the drum 3 and controls the cycle. The pump 24 is formed in a predetermined number of rotations (for example, 2,300 rpm) (see FIG. 17), and the washing water sucked from the drain port 21 is discharged from the nozzle 27a provided in the opening of the outer tub 2 to the inside of the drum 3, and the clothes are carried out. Wash off. Then, when a predetermined time elapses, the control device 38 ends the stirring process.

如此，因為循環泵的旋轉數成為2300rpm左右，所以循環流量減少到35L/min左右，且衣類所含有的洗滌水也少。因此，即使水量少也不會有空氣被吸入到循環泵的情況，可以節水運轉。 As described above, since the number of rotations of the circulation pump is about 2,300 rpm, the circulation flow rate is reduced to about 35 L/min, and the amount of washing water contained in the clothes is small. Therefore, even if the amount of water is small, there is no case where air is sucked into the circulation pump, and the water can be operated.

圖18，是說明在第3實施形態的滾筒式洗衣乾衣機S的洗滌運轉(洗衣~洗清~脫水)，選擇了特殊行程(例如抑制粗糙行程)時的運轉工程的工程圖。第3實施形態的滾筒式洗衣乾衣機S的運轉工程(參照圖17)、與第3實施形態的滾筒式洗衣乾衣機S的運轉工程(參照圖18)，是洗衣工程的預先洗衣攪拌工程到正式洗衣攪拌的工程不同。因為其他的工程(S1~S6、S17~S18)(參照圖17)同樣的，所以省略說明。 FIG. 18 is a view for explaining an operation process when a special stroke (for example, a rough stroke is suppressed) is selected in the washing operation (washing to washing-dehydration) of the drum-type washer-dryer S according to the third embodiment. The operation of the drum-type washer-dryer S of the third embodiment (see FIG. 17) and the operation of the drum-type washer-dryer S of the third embodiment (see FIG. 18) are pre-washing agitation of the laundry project. Engineering to formal laundry mixing is different. Since the other items (S1 to S6, S17 to S18) (see FIG. 17) are the same, the description is omitted.

在步驟S7，控制裝置38是執行預先洗衣攪拌工程。控制裝置38，是控制讓循環泵24成為預定的旋轉數(例如3200rpm)(參照圖18)，而將從排水口21所吸入的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，並且，控制馬達4讓滾筒3以預定的旋轉數(例如40rpm)(參照圖18)進行正反旋轉，藉此讓洗劑濃度高的洗衣水滲入到衣類。當經過預定的時間(例如3分鐘)時，控制裝置38結束預先洗衣攪拌工程進到步驟S8。 At step S7, the control device 38 executes the pre-washing agitation project. The control device 38 controls the circulation pump 24 to have a predetermined number of rotations (for example, 3,200 rpm) (see FIG. 18), and discharges the washing water sucked from the drain port 21 from the nozzle 27a provided in the opening of the outer tub 2. The inside of the drum 3, and the control motor 4 causes the drum 3 to rotate forward and backward at a predetermined number of rotations (for example, 40 rpm) (refer to Fig. 18), thereby allowing the washing water having a high detergent concentration to permeate into the clothes. When a predetermined time (for example, 3 minutes) elapses, the control device 38 ends the pre-washing agitation process and proceeds to step S8.

在步驟S8，控制裝置38是執行正式洗衣攪拌工程。控制裝置38，是控制讓循環泵24成為預定的旋轉數(例如3800rpm)(參照圖18)，而將從排水口21所吸入的洗衣水從被設在外槽2的開口部的噴嘴27a吐出到滾筒3的內部，並且，控制馬達4讓滾筒3以預定的旋轉數(例如40rpm)(參照圖18)進行正反旋轉，藉此對滾筒3的內部的衣類進行拍打洗衣。當經過預定的時間(例如9分鐘)時，控制裝置38結束正式洗衣攪拌工程。 At step S8, the control device 38 performs a formal laundry agitation project. The control device 38 controls the circulation pump 24 to have a predetermined number of rotations (for example, 3,800 rpm) (see FIG. 18), and discharges the washing water sucked from the drain port 21 from the nozzle 27a provided in the opening of the outer tub 2. The inside of the drum 3, and the control motor 4 causes the drum 3 to rotate forward and backward at a predetermined number of rotations (for example, 40 rpm) (refer to FIG. 18), whereby the clothes inside the drum 3 are tapped and washed. When a predetermined time (e.g., 9 minutes) elapses, the control device 38 ends the formal laundry agitation process.

使用者雖在步驟1(S1)選擇運轉行程，可是此時根據運轉行程的選擇，使用者依需要可抑制粗糙。在關於第3實施形態的滾筒式洗衣乾衣機S的運轉工程，使用者可適當選擇重視節水的標準行程、與重視抑制衣類的粗糙的特殊行程。 Although the user selects the operation stroke in step 1 (S1), the user can suppress the roughness as needed according to the selection of the operation stroke. In the operation of the drum-type washer-dryer S of the third embodiment, the user can appropriately select a standard stroke that emphasizes water-saving and a special stroke that emphasizes the suppression of the clothing.

根據本實施形態，標準行程，是執行3分鐘預先洗衣攪拌，執行12分鐘正式洗衣攪拌的合計執行15分鐘讓滾筒3進行正反旋轉的攪拌工程。又，在特殊行程(例如，防止變黑‧粗糙的行程)，是執行3分鐘預先洗衣攪拌，執行9分鐘正式洗衣攪拌的合計執行12分鐘讓滾筒3進行正反旋轉的攪拌工程。亦即，在特殊行程，比標準行程更縮短3分鐘讓滾筒3進行正反旋轉的攪拌時間，可抑制衣類從滾筒3內的上方落下時所施加的落下衝擊(機械力)，並抑制「衣類的粗糙」。又，在特殊行程，因為攪拌時間比標準行程更短，所以從衣類被剝離的污垢在再次附著於衣類前與水一起被排出，所以可抑制「衣類的 變黑」。 According to the present embodiment, the standard stroke is a stirring process in which the drum 3 is rotated forward and reverse for 15 minutes by performing the pre-washing agitation for 3 minutes and performing the total of 12 minutes of the official laundry agitation. Further, in the special stroke (for example, prevention of blackening and rough running), it is a stirring process in which the drum 3 is rotated forward and reverse for 12 minutes by performing the pre-washing stirring for 3 minutes and performing the total laundry stirring for 9 minutes. In other words, in the special stroke, the stirring time of the drum 3 is rotated forward and backward by 3 minutes shorter than the standard stroke, and the falling impact (mechanical force) applied when the clothes are dropped from the upper side of the drum 3 can be suppressed, and the "clothing" is suppressed. Rough." Moreover, in the special stroke, since the stirring time is shorter than the standard stroke, the dirt that has been peeled off from the clothing is discharged together with the water before being attached to the clothing again, so that it is possible to suppress the "clothing". Turn black."

另一方面，因為抑制機械力，會有洗淨性能下降的虞慮。而相對於此，特殊行程的預先洗衣攪拌工程、正式洗衣攪拌工程的循環泵18的流量，是成為3000rpm以上。這是形成比標準行程的預先洗衣攪拌工程、正式洗衣攪拌工程的循環泵18的旋轉數更高。藉此，不僅有可縮短整體的運轉時間的效果，即使洗衣時間變短也可確保洗淨性能。 On the other hand, since the mechanical force is suppressed, there is a concern that the cleaning performance is lowered. On the other hand, the flow rate of the circulation pump 18 of the pre-washing and stirring process of the special stroke and the official laundry mixing process is 3000 rpm or more. This is a higher number of rotations of the circulation pump 18 which forms a pre-washing agitation project and a formal laundry agitation project than the standard stroke. Thereby, not only the effect of shortening the overall operation time but also the washing performance can be ensured even if the washing time is shortened.

如以上，根據第3實施形態的滾筒式洗衣乾衣機S的運轉工程，確保洗淨性能並可抑制衣類的粗糙的情況。 As described above, according to the operation of the drum-type washer-dryer S of the third embodiment, the washing performance can be ensured and the roughness of the clothes can be suppressed.

在以上的實施形態，雖使用滾筒式洗衣乾衣機進行說明，可是即使在不具有乾燥功能的滾筒式洗衣機也同樣。 In the above embodiment, the description will be made using a drum-type washer-dryer, even in a drum-type washing machine that does not have a drying function.
