Description
本發明是關於一種滾筒式洗衣機。 The present invention relates to a drum type washing machine.
以往，已知有用水路連繫被設在內包旋轉槽(內槽)的水槽(外槽)的水取出口與水回流口，並藉由驅動被設在該水路途中的循環泵，一面讓蓄積在水槽的洗滌水循環一面進行洗滌的滾筒式洗衣乾衣機(例如，參照專利文獻1)。 In the past, it has been known that a water outlet and a water return port of a water tank (outer tank) which is provided in a rotary tank (inner tank) are connected by a water passage, and by driving a circulation pump provided in the middle of the water passage, A drum type washing and drying machine that performs washing while circulating the washing water in the water tank (for example, refer to Patent Document 1).
在該滾筒式洗衣乾衣機，進行被投入旋轉槽的洗滌物的洗滌時等，形成使從水取出口暫時被抽出到水槽外的洗滌水再次經由水回流口吐出到水槽內時，將該洗滌水澆到旋轉槽內的洗滌物。藉此，在該滾筒式洗衣乾衣機，讓洗淨水在水槽內效率佳碰到衣類並讓其浸透而可提昇洗滌物的洗淨效果。 In the drum type washing and drying machine, when washing the laundry to be placed in the rotary tub, the washing water that has been temporarily taken out from the water outlet to the outside of the water tank is again discharged into the water tank through the water return port, The washing water is poured into the washings in the rotating tank. Thereby, in the drum-type washer-dryer, the washing water is efficiently immersed in the clothes in the water tank and allowed to permeate, thereby improving the washing effect of the laundry.
又，在專利文獻2，是具備有連接於洗滌槽的前下部的貯水槽，洗滌水或洗清水，是經由給水管給水到貯水槽，並經由循環水管給水到旋轉滾筒內。在洗滌槽的後下部設置從貯水槽的連設部分開的集水部，沿著洗滌槽 的底板流下的水，不會回到貯水槽，而聚集在集水部，並經由連通管及排水管排出到機外，迴避在洗滌槽的底板容易產生的黴菌類混入循環水被導入旋轉滾筒，而附著在旋轉滾筒內的洗滌物的虞慮，並有效防止隨著黴菌類的附著洗滌物的完成品質的低下。 Further, Patent Document 2 includes a water storage tank connected to the front lower portion of the washing tub, and the washing water or the washing water is supplied to the water storage tank via the water supply pipe, and the water is supplied to the rotating drum through the circulating water pipe. Providing a water collecting portion opened from a connecting portion of the water storage tank at a rear lower portion of the washing tub, along the washing tub The water flowing down the bottom plate does not return to the water storage tank, but accumulates in the water collecting portion, and is discharged to the outside of the machine through the communication pipe and the drain pipe, and the mold which is easily generated in the bottom plate of the washing tub is mixed with the circulating water and is introduced into the rotating drum. Moreover, the laundry adhered to the rotating drum is in consideration, and the quality of the finished laundry with the adhesion of molds is effectively prevented from being lowered.

然而，在旋轉槽的旋轉軸傾斜的滾筒式洗衣機與旋轉槽的旋轉軸朝向垂直方向的縱型式洗衣機比較，因其構造上的理由貯水量變少。因此，在以往的滾筒式洗衣機(例如，參照專利文獻1)，為了用少的貯水量來提昇洗淨效果而增長洗滌時間(增長到洗完為止的洗滌水與洗滌物的接觸時間時)時，會有暫時被洗滌水所洗出的皮脂等的汙垢再回到洗滌物的情況。而且，尤其白色物品、淡花樣物品的衣類等，在這樣的滾筒式洗衣機重複洗滌次數時會有逐漸發黑的問題。 However, the drum type washing machine in which the rotation axis of the rotary groove is inclined is smaller in comparison with the vertical type washing machine in which the rotary shaft of the rotary groove is oriented in the vertical direction due to the structural reason. Therefore, in the conventional drum type washing machine (for example, refer to Patent Document 1), in order to increase the washing effect with a small amount of water storage, the washing time is increased (increasing the contact time between the washing water and the laundry until the washing is completed). There is a case where the dirt such as sebum which is temporarily washed out by the washing water is returned to the laundry. Further, in particular, white articles, clothes of light-patterned articles, and the like may have a problem of gradually blackening when such a drum type washing machine repeats the number of washings.
又，在具備連接於洗滌槽的前下部的貯水槽的先前技術(專利文獻2)，雖迴避在洗滌槽的底板容易 產生的黴菌類混入循環水，來防止隨著黴菌類的附著洗滌物的完成品質的低下，可是關於貯水槽的貯水量、循環水的循環量與洗淨效果並沒有任何的提及。又，雖可在水槽外確保讓循環量維持用的水量，可是關於貯水槽的大小並沒有任何的提及。因為貯水槽變大時需要洗滌槽下部的空間，所以滾筒式洗衣乾衣機本體變大會有設置性的問題。因此，期望有即使對洗滌物重覆洗滌次數也能防止發黑的優秀洗淨功能與滾筒式洗衣乾衣機本體的設置性的滾筒式洗衣機。 In addition, in the prior art (Patent Document 2) including the water storage tank connected to the front lower portion of the washing tub, it is easy to avoid the bottom plate of the washing tub. The generated molds are mixed into the circulating water to prevent the deterioration of the quality of the washings accompanying the molds, but there is no mention about the water storage amount of the water storage tank, the circulation amount of the circulating water, and the washing effect. Further, although the amount of water for maintaining the circulation amount can be secured outside the water tank, there is no mention about the size of the water storage tank. Since the space below the washing tank is required when the water storage tank becomes large, the drum type washing and drying machine body has a problem of setting. Therefore, it is desirable to have a drum type washing machine which is capable of preventing the blackening of the washing function and the setting property of the drum type washer-dryer body even if the washing is repeated.
於此，本發明之課題在提供一種，對於洗滌物的洗淨功能比以往更進一步提昇且設置性優的滾筒式洗衣機。 In view of the above, an object of the present invention is to provide a drum type washing machine in which the washing function of the laundry is further improved and the setting property is superior.
本發明者們發現，在滾筒式洗衣機即使蓄積在外槽的洗滌水的水量與以往同樣，藉由將外槽的洗滌水的循環流量設定在預定值以上，可提昇對洗滌物的洗淨功能，進而達到本發明。 The present inventors have found that the amount of water in the washing water accumulated in the outer tub in the drum type washing machine can be improved by the circulating flow rate of the washing water in the outer tubing by a predetermined value or more. Further, the present invention has been achieved.
亦即，解決前述課題的本發明，是一種具備：蓄積洗滌水的外槽；作為可旋轉地設在該外槽內的洗滌兼脫水槽的內槽；旋轉驅動該內槽的驅動裝置；以及讓蓄積在前述外槽的洗滌水循環的循環機構之滾筒式洗衣機，其特徵為：前述循環機構具備：從前述外槽的底部到前述外槽的上部的循環流路；以及被設在該循環流路的途中的循環 泵，在前述外槽的一部分設置2.5L以上的凹陷部，將藉由前述循環機構讓蓄積在前述外槽的洗滌水循環之際的循環流量設定在36L/min以上。 That is, the present invention which solves the above-mentioned problems is an outer tank including a washing water, an inner tank that is rotatably provided in the outer tank, and a driving device that rotationally drives the inner tank; A drum type washing machine for circulating a washing water that circulates in the outer tank is characterized in that the circulation mechanism includes a circulation flow path from a bottom portion of the outer tank to an upper portion of the outer tank, and is provided in the circulation flow. Cycle on the way In the pump, a recessed portion of 2.5 L or more is provided in a part of the outer tank, and the circulation flow rate at the time of circulating the washing water accumulated in the outer tank by the circulation mechanism is set to 36 L/min or more.
根據本發明之滾筒式洗衣機，可提供一種設置性優，且對於洗滌物的洗淨功能比以往更進一步提昇的滾筒式洗衣機。 According to the drum type washing machine of the present invention, it is possible to provide a drum type washing machine which is excellent in versatility and which has a further improved washing function for laundry than in the past.

The depressed portion 2f has a width Wk of 200 mm, a depth H of 50 mm, a deep side L of 250 mm, and a volume of 2.5 L. Further, the bottom surface of the recessed portion 2f is an inclined surface that is formed to descend from the front side toward the rear side, and a drain port 21 is provided on the rear side of the recessed portion 2f. A bellows tube 22 is connected to the drain port 21 via a joint 21a. An inflow port 18 for circulating water at the bottom is provided on the front side of the recessed portion 2f.
符號26是排水軟管，在後述的循環泵24的出水埠23b(參照圖4(a))連接有其一端，其另一端側延出到機外。符號25是被設在排水軟管26在機內延伸的途中的排水閥。 Reference numeral 26 is a drain hose, and one end of the water discharge port 23b (see Fig. 4(a)) of the circulation pump 24 to be described later is connected, and the other end side thereof is extended to the outside of the machine. Reference numeral 25 is a drain valve provided in the middle of the drain hose 26 extending in the machine.
圖3(a)為圖2的III-III剖視圖，即被形成在外槽的底部的凹陷部的說明圖，圖3(b)是被形成在以往的滾筒式洗衣乾衣機的外槽的底部的凹陷部的說明圖。 Fig. 3 (a) is a cross-sectional view taken along line III-III of Fig. 2, that is, an explanatory view of a depressed portion formed at the bottom of the outer tub, and Fig. 3 (b) is formed at the bottom of the outer tub of the conventional drum type washer-dryer; An illustration of the depressed portion.
如圖3(a)所示，在凹陷部2f的上部形成有從外槽2的外周壁的內周面連續的隔壁W且覆蓋凹陷部2f的寬幅的大致一半。隔壁W是在對於洗滌兼脫水槽3的脫水時的旋轉方向R對抗的方向沿著洗滌兼脫水槽3的 外周面地延出。排水口21及流入口18是被形成在從凹陷部2f的寬幅方向的中心朝洗滌兼脫水槽3的旋轉方向偏離的位置。藉此形成在排水口21與流入口18的上部配置有隔壁W。 As shown in FIG. 3(a), a partition wall W continuous from the inner peripheral surface of the outer peripheral wall of the outer tub 2 is formed in the upper portion of the recessed portion 2f, and covers approximately half of the width of the recessed portion 2f. The partition wall W is along the washing and dewatering tank 3 in the direction against which the rotation direction R at the time of dehydration of the washing and dewatering tank 3 is opposed. The outer circumference is extended. The drain port 21 and the inflow port 18 are formed at positions deviated from the center in the width direction of the recessed portion 2f toward the rotation direction of the washing and dewatering tank 3. Thereby, the partition wall W is formed in the upper part of the drain port 21 and the inflow port 18.
凹陷部2f是在脫水時，水利用洗滌兼脫水槽3的旋轉產生的離心力，從洗滌兼脫水槽3的貫穿孔(省略圖示)朝向外槽2的內周面側跑出去時，接著流到與洗滌兼脫水槽3的旋轉方向同一方向的水，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 washing and dewatering tank 3 during the dehydration, and flows out from the through hole (not shown) of the washing and dewatering tank 3 toward the inner peripheral surface side of the outer tub 2, and then flows. The water in the same direction as the rotation direction of the washing and dewatering tank 3 is guided 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2 f的容積在1~1.5L(凹陷部2f的寬幅Wk是120mm，深度H是50mm，深側L是250mm)左右，而相對於此，圖3(a)所示的本實施例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 volume of the recessed portion 2f of the conventional drum type washer-dryer shown in Fig. 3(b) is 1 to 1.5 L (the width Wk of the recessed portion 2f is 120 mm, the depth H is 50 mm, and the deep side L is On the other hand, the volume of the depressed portion 2f of the drum-type washer-dryer S of the present embodiment shown in Fig. 3 (a) is set to 2.5 L or more.

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)從排水軟管26排水到機外。 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 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3000~5000r/min的旋轉速度進行旋轉。該旋轉速度，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 be rotatable at a rotational speed of 3000 to 5000 r/min in order to secure a circulating flow rate to be described later. This rotation speed is controlled by the control device 38 (see Fig. 2) as will be described later.
接著，參照的圖6(a)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6(b)表示被設在外槽罩蓋的循環流路的立體圖。圖7為連接在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。 6(a) is a perspective view showing a bellows pipe connected to a circulation pump and a circulation flow path provided in the outer tank cover, and FIG. 6(b) is a perspective view showing a circulation flow path provided in the outer tank cover. Fig. 7 is a partially enlarged perspective view showing the vicinity of a nozzle provided in a circulation flow path provided in the outer tank cover.
如圖6(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。 As shown in Figs. 6(a) and 6(b), the bellows 41 having one end connected to the discharge port 44 of the circulation pump 24 is an inlet port 2g for connecting the other end thereof to the circulation flow path 27.
該入口埠2g是如圖6(b)所示被形成在外槽罩蓋2d的外周面。 This inlet port 2g is formed on the outer peripheral surface of the outer tank cover 2d as shown in Fig. 6 (b).
本實施例的循環流路27是如圖6(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。該循環流路27的剖面形狀並沒特別限制，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。 The circulation flow path 27 of the present embodiment is constituted by a tubular passage integrally formed on the inner peripheral wall of the resin outer cover 2d as shown in Fig. 6(a). 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 is not particularly limited, and may be circular, elliptical, polygonal or the like. The cross-sectional area of the circulation flow path 27 is converted into a circle Those with a diameter of 25 mm or more are expected.
根據本實施例的循環流路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槽罩蓋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，而即使萬一破損，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由於與外槽罩蓋2d被一體成形，所以零件件數比起以往者可以少。 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 tank cover 2d. The concern is further reduced, and even if it is broken, there is no case where the washing water leaks to the outside of the outer tank 2. Further, since the circulation flow path 27 is integrally formed with the outer groove cover 2d, the number of components can be reduced as compared with the conventional one.
噴嘴27a是將從循環泵(參照圖5)的吐出埠44所吐出的洗滌水從外槽罩蓋2d的上部朝向洗滌兼脫水槽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 (see FIG. 5) from the upper portion of the outer tank cover 2d toward the washing and dewatering tank 3 (see FIG. 2).
該噴嘴27a是如圖7所示，其開口形成細縫狀，而形成可使洗滌水呈薄膜狀展開噴射。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。 As shown in Fig. 7, the nozzle 27a has a slit formed in a slit shape, and is formed so that the washing water can be sprayed in a film form. Further, since the circulation flow rate of the washing water is increased as compared with the related art, the force of the slit width (gap width) of the nozzle 27a is not weakened even if it is wider than the conventional one. 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.
又，在外槽罩蓋2d是形成與循環流路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。 Further, the outer tank cover 2d is formed with a small hole H that communicates with the circulation flow path 27, and is 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.
從該小孔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，形成洗去附著在波紋管10的裏側的線屑等。 When the washing water sprayed from the small hole 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 is formed.
接著，針對控制裝置38(參照圖2)進行說 明。 Next, the control device 38 (refer to FIG. 2) is said. Bright.
控制裝置38具備微電腦、驅動電路等，並且也具備從圖2所示的操作按鈕12、13的開閉訊號、從各種感應器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。 The control device 38 includes a microcomputer, a drive circuit, and the like, and also includes an open/close signal from the operation buttons 12 and 13 shown in FIG. 2, an input circuit for outputting signals from various sensors, and the like. In addition, the microcomputer accepts the user's operation; various information signals in the washing and drying projects. The microcomputer is connected to the motor 4, the water supply solenoid valve 16, the drain valve 25, the blower fan (not shown), and the like via a drive circuit to control the opening, closing, rotation, and energization of the motor. 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.
圖8表示圖1的滾筒式洗衣乾衣機的控制裝置執行的控制處理的一部分的流程圖。圖9表示圖1的滾筒式洗衣乾衣機的控制裝置執行的控制處理的其他的一部分的流程圖。 Fig. 8 is a flow chart showing a part of a control process executed by the control device of the drum-type washer-dryer of Fig. 1. Fig. 9 is a flow chart showing another part of the control process executed by the control device of the drum-type washer-dryer of Fig. 1.
如圖8所示，因使用者的操作電源開關39(參照圖1)開啟時，控制裝置38進行滾筒式洗衣乾衣機S的狀態確認的同時，進行滾筒式洗衣乾衣機S的初期設定(步驟S101)。 As shown in FIG. 8, when the user operates the power switch 39 (refer to FIG. 1), the control device 38 confirms the state of the drum-type washer-dryer S, and performs initial setting of the drum-type washer-dryer S. (Step S101).
控制裝置38按照使用者的操作按鈕13的操作設定洗滌行程(步驟S102)。亦即，只要選擇通常的洗滌行程；或是用比該洗滌行程的循環流量更大的循環流量進行洗滌及洗清的高循環流量行程(白色物的洗滌行程)的任一行程。 The control device 38 sets the washing course in accordance with the operation of the user's operation button 13 (step S102). That is, any one of the strokes of the high circulation flow stroke (washing stroke of the white matter) for washing and washing is performed by using a normal washing stroke or a circulation flow rate larger than the circulation flow rate of the washing stroke.
通常的洗滌行程的循環流量預先被設定在15~20L/min的範圍內。又，高循環流量行程的循環流量是 被設定在36L/min以上。該循環流量，是可由洗滌水的循環時在蛇腹管22內流的洗滌水的循環流量所界定。 The circulation flow rate of the usual washing stroke is set in advance in the range of 15 to 20 L/min. Moreover, the circulating flow rate of the high circulation flow stroke is It is set at 36L/min or more. The circulating flow rate is defined by the circulating flow rate of the washing water flowing in the bellows 22 when the washing water is circulated.
此外，雖沒有循環流量的上限，可是如後述，因為超過52L/min時會有不認同其增加量相對應的洗淨功能的提昇的情況，所以循環流量也可設定在36~52L/min。 In addition, although there is no upper limit of the circulation flow rate, as will be described later, since the cleaning function corresponding to the increase amount is not recognized when it exceeds 52 L/min, the circulation flow rate can be set to 36 to 52 L/min.
本實施例的「通常的洗滌行程」的循環流量，是控制裝置38將循環泵馬達47的旋轉速度設定在2300~2800r/min而能維持在前述範圍內(15~20L/min)。 The circulation flow rate of the "normal washing stroke" in the present embodiment is such that the control device 38 sets the rotation speed of the circulation pump motor 47 to 2300 to 2800 r/min and can be maintained within the above range (15 to 20 L/min).
又，「高循環流量行程」的循環流量，是控制裝置38將循環泵馬達47的旋轉速度設定在3000~5000r/min，而能維持在前述範圍內(36L/min以上)。 Further, the circulation flow rate of the "high circulation flow rate" is such that the control device 38 sets the rotation speed of the circulation pump motor 47 to 3,000 to 5,000 r/min, and can be maintained within the above range (36 L/min or more).
此外，本實施例的洗滌行程的設定(步驟S102)，由於在「通常的洗滌行程」與「高循環流量行程」假設僅循環流量的設定範圍與前述不同，所以在以下僅針對選擇了「高循環流量行程」的情況進行說明，而選擇了「通常的洗滌行程」時的說明則予以省略。 In addition, in the setting of the washing stroke of the present embodiment (step S102), since the setting range of the circulating flow rate is assumed to be different between the "normal washing stroke" and the "high circulation flow stroke", only the "high" is selected below. The case of the "circulation flow stroke" will be described, and the description when the "normal washing stroke" is selected will be omitted.
接著，在步驟S103，控制裝置38是監視來自作為操作面板6的開始開關的操作按鈕12的指示輸入，確認開始開關訊號的有無。不能被確認時(步驟S103「無」時)重複步驟S103。而且，控制裝置38在確認開始開關訊號時(步驟S103「有」的時後)，進入到步驟S104，執行洗劑量的檢出處理。 Next, in step S103, the control device 38 monitors an instruction input from the operation button 12 as a start switch of the operation panel 6, and confirms the presence or absence of the start switch signal. If it is not confirmed (when step S103 "None"), step S103 is repeated. When the control device 38 confirms the start of the switching signal (after "YES" in step S103), the control device 38 proceeds to step S104 to execute the detection processing of the washing amount.
該洗劑量檢出，是依據在給水洗滌水之前的乾布狀態，讓洗滌兼脫水槽3朝一方向旋轉時，馬達4從規定的第1旋轉速度增速到規定的第2旋轉速度的期間的驅動電流估算值檢出洗滌物的質量。而且，依據所檢出的洗滌物的質量算出使用的洗劑的適量(洗劑量)實施該洗劑量檢出的工程(步驟S104)。洗劑量的算出，是控制裝置38參照界定洗滌物的質量與所使用的洗劑量的關係的對照表來進行。 The detection of the washing amount is based on the state of the dry cloth before the water supply washing water, and the driving of the washing and dewatering tank 3 in one direction, the driving of the motor 4 from the predetermined first rotation speed to the predetermined second rotation speed. The current estimate detects the quality of the laundry. Then, an appropriate amount (washing amount) of the used lotion is calculated based on the detected mass of the laundry (step S104). The calculation of the washing dose is performed by the control unit 38 with reference to a comparison table defining the relationship between the quality of the laundry and the amount of washing used.
控制裝置38是在操作面板6的顯示器14顯示所算出的洗劑量(步驟S105)。使用者將該顯示的洗劑量投入洗劑承盤7，控制裝置38是在經過預先所決定的預定時間(例如1分鐘)時，打開給水電磁閥16對洗劑承盤7灑水。藉此，對外槽2內供給洗劑(步驟S106)。 The control device 38 displays the calculated washing amount on the display 14 of the operation panel 6 (step S105). The user puts the displayed washing dose into the lotion holder 7, and the control device 38 opens the water supply solenoid valve 16 to sprinkle the lotion tray 7 when a predetermined time (for example, 1 minute) has elapsed. Thereby, the lotion is supplied into the outer tank 2 (step S106).
接著，控制裝置38是在外槽2內的水位到達預先所設定的洗劑溶解水位之際關閉給水電磁閥16停止給水(步驟S107)。 Next, the control device 38 closes the water supply solenoid valve 16 to stop the water supply when the water level in the outer tank 2 reaches the previously set lotion dissolved water level (step S107).
而且，控制裝置38使循環泵馬達47逆旋轉，而使外槽2內的水經由蛇腹管22及蛇腹管40進行循環。藉此，成為可溶解被蓄積在外槽2的底部及凹陷部2f的洗劑(步驟S108)。 Further, the control device 38 reversely rotates the circulation pump motor 47, and circulates the water in the outer tub 2 through the bellows tube 22 and the bellows tube 40. Thereby, the lotion which can be dissolved in the bottom portion of the outer tub 2 and the recessed portion 2f is dissolved (step S108).
在步驟S109，執行旋轉給水工程，該工程是控制給水電磁閥16，讓外槽6內的洗滌水的水位上昇，並且讓洗滌兼脫水槽3以預定的旋轉數進行旋轉來進行衣 類的翻轉。具體而言，控制裝置38邊打開給水電磁閥16邊控制馬達4，讓洗滌兼脫水槽3以大致40r/min進行旋轉，並且讓循環泵馬達47以未滿3000r/min的旋轉速度(例如2600r/min)進行旋轉。藉此，從排水口21被吸入的洗滌水從被設在外槽2的開口部的噴嘴27a被吐出到洗滌兼脫水槽3的內部，使其滲透到洗滌兼脫水槽3的內部的洗滌物。而且，當外槽內2內的洗滌水的水位上昇到預定的水位時，令給水停止((關閉給水電磁閥16)。 In step S109, a rotary water supply project is executed which controls the water supply solenoid valve 16 to raise the water level of the washing water in the outer tank 6, and rotates the washing and dewatering tank 3 by a predetermined number of rotations. The flip of the class. Specifically, the control device 38 controls the motor 4 while opening the water supply solenoid valve 16, rotates the washing and dehydrating tank 3 at approximately 40 r/min, and causes the circulation pump motor 47 to rotate at a speed of less than 3000 r/min (for example, 2600 r /min) Rotate. By this, the washing water that has been sucked into the washing and dewatering tank 3 is discharged into the washing and dewatering tank 3 from the nozzle 27a provided in the opening of the outer tank 2 and is allowed to permeate into the washing and dewatering tank 3. Further, when the water level of the wash water in the outer tank 2 rises to a predetermined water level, the feed water is stopped ((the feed water solenoid valve 16 is closed).
在步驟S110，執行增加循環流量讓洗滌水充分滲入到洗滌物，並利用洗滌兼脫水槽3的旋轉形成的離心力使滲入的洗滌水通過洗滌物時的流體力去除污垢的一部分的前洗衣(第1攪拌工程)。具體而言，控制裝置38控制馬達4，讓洗滌兼脫水槽3用60r/min以上的旋轉數(例如100r/min)進行旋轉，藉此，防止利用離心力讓洗滌兼脫水槽3的內部的洗滌物貼在洗滌兼脫水槽的外周壁內面，當其從洗滌兼脫水槽3的上方落下時產生的機械性的力的施加。 In step S110, the pre-washing is performed by increasing the circulating flow rate so that the washing water sufficiently permeates into the laundry, and using the centrifugal force formed by the rotation of the washing and dewatering tank 3 to remove the part of the dirt by the fluid force when the infiltrated washing water passes through the washing. 1 mixing project). Specifically, the control device 38 controls the motor 4 to rotate the washing and dehydrating tank 3 by a rotation number of 60 r/min or more (for example, 100 r/min), thereby preventing the inside of the washing and dewatering tank 3 from being washed by centrifugal force. The application is applied to the inner surface of the outer peripheral wall of the washing and dewatering tank, and the mechanical force generated when it falls from above the washing and dewatering tank 3 is applied.
此時，控制裝置38，是用預定的旋轉速度(3000~5000r/min)讓循環泵馬達47進行正旋轉，而使洗滌水的循環流量成為36L/min以上。如此，一面使洗滌兼脫水槽3旋轉，一面藉由旋轉循環泵馬達47將外槽2的洗滌水經由蛇腹管22、蛇腹管41、循環流路27、及噴嘴27a澆到洗滌兼脫水槽3內的洗滌物。 At this time, the control device 38 causes the circulation pump motor 47 to rotate positively at a predetermined rotation speed (3000 to 5000 r/min) to set the circulation flow rate of the washing water to 36 L/min or more. In this manner, the washing and dewatering tank 3 is rotated, and the washing water of the outer tank 2 is poured into the washing and dewatering tank 3 via the bellows tube 22, the bellows tube 41, the circulation flow path 27, and the nozzle 27a by the rotary circulation pump motor 47. Washing inside.
接著，在步驟S111，執行藉由洗滌兼脫水槽 3的旋轉掀起蓄積在洗滌兼脫水槽3內的下方的洗滌物，讓其從洗滌兼脫水槽3內的上方落下，藉此，進行對洗滌物賦予機械性的力的拍打洗衣之正式洗衣工程(第2攪拌工程)。具體而言，控制裝置38控制馬達4，藉由讓洗滌兼脫水槽3以60r/min以下的旋轉數(例如40r/min)正反交替旋轉(正反加起來每分鐘35旋轉至45旋轉)，進行洗滌兼脫水槽3的內部的洗滌物拍打洗衣。 Next, in step S111, the washing and dewatering tank is performed. The rotation of 3 is caused by the laundry that has accumulated in the washing and dewatering tank 3, and is dropped from above in the washing and dewatering tank 3, thereby performing a formal laundry operation of the laundry that imparts a mechanical force to the laundry. (2nd mixing project). Specifically, the control device 38 controls the motor 4 to alternately rotate the washing and dehydrating tank 3 by a rotation number of 60 r/min or less (for example, 40 r/min) (plus 35 to 45 rotations per minute). The washing and washing of the inside of the washing and dewatering tank 3 is performed.
此時，控制裝置38，是讓循環泵馬達47以預定的旋轉速度(3000~5000r/min)進行正旋轉，而與前述同樣利用前述的循環流量從噴嘴27a將外槽2的洗滌水澆到洗滌物。最後，控制裝置38，是停止循環泵24的運轉並止住洗滌水的循環，一面在短周期讓洗滌兼脫水槽3正反交替旋轉，一面進行預定時間鬆解洗滌物的運轉讓正式洗衣工程(步驟S111)結速。 At this time, the control device 38 causes the circulation pump motor 47 to perform the normal rotation at a predetermined rotation speed (3000 to 5000 r/min), and the washing water of the outer tank 2 is poured from the nozzle 27a to the same circulating flow rate as described above. Washing. Finally, the control device 38 stops the operation of the circulation pump 24 and stops the circulation of the washing water, and simultaneously rotates the washing and dehydrating tank 3 in the short cycle, and releases the washing operation for a predetermined period of time to complete the laundry. (Step S111) The junction speed.
如圖9所示，在接著步驟S111(參照圖8)被執行的步驟S112，控制裝置38執行第1次的洗清。 As shown in FIG. 9, in step S112, which is executed in step S111 (see FIG. 8), the control device 38 executes the first washing.
在該洗清，控制裝置38首先打開排水閥25進行外槽2內的水的排水。控制裝置38是用水位感應器34感測排水完成之後，讓洗滌兼脫水槽3朝一方向(在本實施例，從滾筒式洗衣乾衣機S的前方(正面)觀看朝逆時針方向)旋轉離心脫掉含在洗滌物的洗衣水。 In this washing, the control device 38 first opens the drain valve 25 to drain the water in the outer tub 2. After the water level sensor 34 senses the completion of the drainage, the control device 38 rotates the washing and dewatering tank 3 in one direction (in the present embodiment, viewed from the front (front) of the drum-type washer-dryer S in a counterclockwise direction). Take off the washing water contained in the laundry.
之後，控制裝置38打開給水電磁閥16將自來水給水到外槽2內。接著，執行與正式洗衣工程(步驟S111)同樣，一面讓洗滌兼脫水槽3反轉旋轉(每分鐘 35旋轉至45旋轉)，一面讓循環泵馬達47正旋轉，來進行從噴嘴27a將蓄積在外槽2的底部的洗清水澆到洗滌物這樣的循環的洗清。洗清水的循環流量，是與在正式洗衣工程(步驟S111)的循環流量同樣設定在36L/min以上。該循環流量也可與前述同樣理由設定在36~52L/min。 Thereafter, the control device 38 opens the feed water solenoid valve 16 to supply tap water into the outer tank 2. Then, similarly to the official laundry process (step S111), the washing and dewatering tank 3 is reversely rotated (per minute When the circulation pump motor 47 is rotated in the forward direction, the circulating pump motor 47 is rotated, and the washing of the circulation of the washing water accumulated in the bottom of the outer tank 2 from the nozzle 27a is carried out. The circulation flow rate of the washing water is set to be 36 L/min or more in the same manner as the circulation flow rate in the main laundry (step S111). The circulation flow rate can also be set at 36 to 52 L/min for the same reason as described above.
接著，控制裝置38在停止洗滌兼脫水槽3的旋轉與循環泵24的運轉的狀態下，一面利用水位感應器34檢出蓄積在外槽2的底部的洗清水的水位，一面進行水位不會超過設定水位的補給水。 Next, when the control device 38 stops the rotation of the washing and dehydrating tank 3 and the operation of the circulation pump 24, the water level sensor 34 detects the water level of the washing water accumulated in the bottom of the outer tank 2, and the water level does not exceed Set the water supply for the water level.
而且，執行一面讓洗滌兼脫水槽3反轉旋轉(每分鐘35旋轉至45旋轉)，一面讓循環泵馬達47正旋轉，來進行從噴嘴27a將蓄積在外槽2的底部(凹陷部2f)的洗清水澆到洗滌物這樣的循環的洗清。 In addition, while the washing and dewatering tank 3 is reversely rotated (35 rotations to 45 rotations per minute), the circulation pump motor 47 is rotated in the forward direction, and the bottom portion (recessed portion 2f) of the outer tank 2 is accumulated from the nozzle 27a. Wash the water and wash it into a cycle of washing.
洗清水的循環流量是設定在36L/min以上。該循環流量也可與前述同樣理由設定在36~52L/min。之後，控制裝置38，是在停止循環泵24並止住洗清水的循環狀態下，讓洗滌兼脫水槽3在短周期進行正反旋轉，並進行鬆解運轉。 The circulating flow rate of the washing water is set at 36 L/min or more. The circulation flow rate can also be set at 36 to 52 L/min for the same reason as described above. Thereafter, the control device 38 causes the washing and dehydrating tank 3 to rotate forward and backward in a short cycle while the circulation pump 24 is stopped and the washing water is stopped, and the releasing operation is performed.
在步驟S113，除了在外槽2內投入柔軟完成劑以外，進行與第1次的洗清工程(步驟S112)同樣的洗清工程(第2次洗清工程)。 In step S113, a cleaning process (second cleaning process) similar to the first cleaning process (step S112) is performed in addition to the addition of the softening agent in the outer tank 2.
在步驟S114執行脫水處理。控制裝置38是在開放著排水閥25的狀態下，讓洗滌兼脫水槽3朝一方 向(在本實施例，從滾筒式洗衣乾衣機S的前方(正面)觀看朝逆時針方向)旋轉離心脫掉含在洗滌物的洗衣水。 The dehydration process is performed in step S114. In the control device 38, the washing and dehydrating tank 3 is placed in a state in which the drain valve 25 is opened. To (in the present embodiment, the counterclockwise direction is viewed from the front (front) of the drum type washer-dryer S), the washing water contained in the laundry is removed by centrifugal centrifugation.
接著，控制裝置38，根據使用者的選擇執行烘乾工程(步驟S115)的時候，在開放排水閥25的狀態下，與洗滌工程同樣讓洗滌兼脫水槽3正反旋轉。而且，控制裝置38是藉由運轉設在烘乾通道29中途的送風扇，將外槽2內的空氣吸出到烘乾通道29內。 Next, when the drying device is executed in accordance with the user's selection (step S115), the control device 38 rotates the washing and dehydrating tank 3 in the same manner as the washing process in the state where the drain valve 25 is opened. Further, the control device 38 sucks the air in the outer tub 2 into the drying duct 29 by operating the blower fan provided in the middle of the drying duct 29.
通過該烘乾通道29內的空氣，是與從設置在烘乾通道29內的除濕機構流落的冷卻水接觸而被冷卻之後，通過棉絮濾器捕集一起的線屑等。而且，該空氣，是藉由加熱器被加熱之後從溫風吹出口吹入洗滌兼脫水槽3內，藉此烘乾洗滌兼脫水槽3內的洗滌物。實施以上這樣一連串的各工程，結束該控制裝置38所為的滾筒式洗衣乾衣機S的洗滌．乾燥運轉工程。 The air passing through the drying duct 29 is cooled by contact with the cooling water flowing from the dehumidifying mechanism provided in the drying duct 29, and then collected by the batt filter. Then, the air is blown into the washing and dewatering tank 3 from the warm air blowing port by being heated by the heater, thereby drying the laundry in the washing and dewatering tank 3. The series of the above-mentioned various projects are carried out, and the washing of the drum type washing and drying machine S by the control device 38 is ended. Dry operation engineering.
接著，針對本實施例的滾筒式洗衣乾衣機S的作用效果進行說明。 Next, the effect of the drum-type washer-dryer S of the present embodiment will be described.
以往的滾筒式洗衣乾衣機的洗滌水的循環流量一般被設定在15~20L/min左右的時候，在本實施例的滾筒式洗衣乾衣機S形成可將循環流量設定在36L/min以上的構造。 When the circulating flow rate of the washing water of the conventional drum-type washer-dryer is generally set to about 15 to 20 L/min, the drum-type washer-dryer S of the present embodiment can be set to set the circulation flow rate to 36 L/min or more. Construction.
具體而言，構成洗滌水的循環流路的配管中，至少連接外槽2的排水口21與循環泵24來從外槽2抽出洗滌水的位在循環泵24的上游側的蛇腹管22的內徑被設在35mm以上，期望是被設在37mm~50mm，該蛇腹 管22的長度400mm以下，期望是被設在150~300mm。 Specifically, among the pipes constituting the circulation flow path of the washing water, at least the drain port 21 of the outer tank 2 and the circulation pump 24 are connected to draw the washing water from the outer tank 2 at the upstream side of the circulatory pump 24 The inner diameter is set at 35mm or more, and it is expected to be set at 37mm~50mm. The length of the tube 22 is 400 mm or less, and it is desirably set to 150 to 300 mm.
而且，以循環泵24的循環泵馬達47來說，是使用其旋轉速度可實現3000r/min以上，期望是使用可實現3800~5000r/min者。 Further, the circulation pump motor 47 of the circulation pump 24 can achieve a rotation speed of 3000 r/min or more, and it is desirable to use 3800 to 5000 r/min.
此外，從循環泵24朝向外槽罩蓋2d送入洗滌水之位在循環泵24的下游側的蛇腹管41的內徑是被設定在20以上，期望是被設定在25~35mm左右。 In addition, the inner diameter of the bellows tube 41 on the downstream side of the circulation pump 24 from the circulation pump 24 to the outer tank cover 2d is set to be 20 or more, and is desirably set to about 25 to 35 mm.
在這樣的本實施例的滾筒式洗衣乾衣機S，從外槽2的排水口21回到循環泵24的洗滌水變的良好，所以洗滌水的循環流量提昇。而且，根據該滾筒式洗衣乾衣機S，與以往的滾筒式洗衣乾衣機S(例如參照專利文獻1)比較，即使貯留在外槽2內的洗滌水的水量相同，藉由將外槽2的洗滌水的循環流量設定在前述範圍，可使對於洗滌物的洗淨功能提昇。例如即使外槽2的貯水量與以往的滾筒式洗衣乾衣機相同，在該滾筒式洗衣乾衣機S比以往更提昇對於變黑等的洗淨功能的原因，可想到的是藉由使得從噴嘴27a噴射到洗滌物的洗滌水的水量增加，可縮短洗滌時間(洗滌水與洗滌物的接觸時間)，且可降低在洗滌水暫時被洗出的皮脂等的污垢再次回到洗滌物的量者。 In the drum-type washer-dryer S of this embodiment, the washing water returned from the drain port 21 of the outer tub 2 to the circulation pump 24 is improved, so that the circulating flow rate of the washing water is increased. In addition, according to the drum-type washer-dryer S, compared with the conventional drum-type washer-dryer S (for example, refer patent document 1), even if the amount of wash water stored in the outer tank 2 is the same, by the outer tank 2 The circulation flow rate of the washing water is set to the above range, and the washing function for the laundry can be improved. For example, even if the amount of water stored in the outer tub 2 is the same as that of the conventional drum-type washer-dryer, it is conceivable that the drum-type washer-dryer S has a function of cleaning the blackening function or the like more than ever. The amount of water of the washing water sprayed from the nozzle 27a to the laundry is increased, the washing time (contact time of the washing water and the laundry) can be shortened, and the dirt such as sebum temporarily washed out in the washing water can be reduced to return to the laundry. Quantity.
又，根據該滾筒式洗衣乾衣機S，由於可縮短洗滌時間(洗滌水與洗滌物的接觸時間)，所以可減少洗滌物在洗滌兼脫水槽3內的動作，具體而言，可減少藉由昇降機構掀起洗滌物使其落下的動作的次數，並可抑制洗 滌後的粗糙感。尤其，在前洗衣工程，讓洗滌兼脫水槽3以60r/min以上的旋轉數進行旋轉，可讓洗滌物貼在洗滌兼脫水槽3，且藉由抑制拍打洗衣減低粗糙感。此外，在前洗衣工程，抑制拍打洗衣而下降的洗淨性能，是可藉由循環流量的增加進行彌補。 Moreover, according to the drum-type washer-dryer S, since the washing time (contact time of the washing water and the laundry) can be shortened, the movement of the laundry in the washing and dewatering tank 3 can be reduced, and specifically, the borrowing can be reduced. The number of times the laundry is lifted by the lifting mechanism to cause it to fall, and the washing can be suppressed Rough feeling after washing. In particular, in the pre-washing process, the washing and dewatering tank 3 is rotated at a number of revolutions of 60 r/min or more, so that the laundry can be attached to the washing and dewatering tank 3, and the roughness can be reduced by suppressing the tapping laundry. In addition, in the front laundry project, the washing performance which is suppressed by the tapping of the laundry is compensated by an increase in the circulation flow rate.
以上，雖針對本發明的實施例作了說明，可是本發明並不限定於前述實施例，可在各種的形態進行實施。 The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and can be implemented in various forms.
在前述實施例，以蛇腹管41來說，雖是假設使用其內徑成為前述預定範圍者，可是只要可將循環流量設定在36L/min以上，便可使用與以往同樣的內徑者。 In the above-described embodiment, the bellows 41 is assumed to have the inner diameter of the predetermined range. However, as long as the circulation flow rate can be set to 36 L/min or more, the same inner diameter as in the related art can be used.
在前述實施例，雖使用蛇腹管22、41，可是形成該等的循環流路的配管不限於圓形剖面者，可使用橢圓、多角形等的各式各樣者。此時，配管的剖面積換算成圓形者之際可使用成為前述內徑這樣的東西。 In the above-described embodiment, the bellows tubes 22 and 41 are used. However, the piping forming the circulation passages is not limited to a circular cross section, and various types such as an ellipse and a polygon may be used. In this case, when the cross-sectional area of the pipe is converted into a circular shape, it is possible to use the inner diameter.
又，在前述實施例，雖假設外槽罩蓋2d的循環流路27從入口埠2g沿著外槽罩蓋2d的開口跨大致半周延伸存在者，可是也可是跨外槽罩蓋2d的開口的大致全周延伸存在者。又，前述循環流路27雖是從入口埠2g沿著外槽罩蓋2d的開口朝向一方向延伸存在，可是也可設成從入口埠2g分歧呈二方向地沿著外槽罩蓋2d的開口延伸存在的構成。根據這樣的分歧型的循環流路27，可將噴嘴27a的配置處沿著外槽罩蓋2d的開口配置2處以上。此時，各噴嘴27a，是以外槽罩蓋2d的開口的上部 作為0點鐘位置時，設置在3點鐘位置至9點鐘位置之間為期望。 Further, in the foregoing embodiment, it is assumed that the circulation flow path 27 of the outer tank cover 2d extends from the inlet 埠 2g along the opening of the outer tank cover 2d over substantially half a circumference, but may be an opening across the outer tank cover 2d. The extension extends substantially throughout the week. Further, the circulation flow path 27 extends from the inlet port 2g along the opening of the outer tank cover 2d in one direction, but may be provided so as to be branched from the inlet port 2g in two directions along the outer groove cover 2d. The configuration in which the opening extends. According to such a bifurcation type circulation flow path 27, the arrangement of the nozzles 27a can be arranged at two or more positions along the opening of the outer tank cover 2d. At this time, each nozzle 27a is an upper portion of the opening of the outer tank cover 2d. As the 0 o'clock position, it is desirable to set between the 3 o'clock position and the 9 o'clock position.
接著，依據實施例更具體地針對本發明進行說明。 Next, the present invention will be described more specifically in accordance with the embodiments.
在本實施例，驗證圖1所示的滾筒式洗衣乾衣機S的循環流量與洗淨比的關係。 In the present embodiment, the relationship between the circulation flow rate and the washing ratio of the drum-type washer-dryer S shown in Fig. 1 was verified.
滾筒式洗衣乾衣機S的蛇腹管22的內徑是40mm。蛇腹管22的長度是270mm。外槽罩蓋2d的循環流路27的剖面積，是使用剖面換算成圓形者時的內徑相當於25mm者。以洗滌物來說是使用JIS試驗布4.5kg。此外，洗劑是使用預先用水1L溶解其1.8g者。 The inner diameter of the bellows tube 22 of the drum type washer-dryer S is 40 mm. The length of the bellows tube 22 is 270 mm. The cross-sectional area of the circulation flow path 27 of the outer tank cover 2d is equivalent to an inner diameter of 25 mm when the cross section is converted into a circular shape. In the case of laundry, 4.5 kg of JIS test cloth was used. Further, the lotion was prepared by dissolving 1.8 g of it in 1 L with water in advance.
而且，測量使循環泵24的旋轉速度在3000rpm~6000r/min的範圍內進行變化來實施洗滌之際的洗淨比。在圖10表示其結果。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(JIS C9811)』所規定。亦即，洗淨比愈高，洗淨性能愈高。 Further, the washing rate at the time of washing was measured by changing the rotational speed of the circulation pump 24 in the range of 3000 rpm to 6000 r/min. The result is shown in FIG. 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 (JIS C9811)". That is, the higher the washing ratio, the higher the washing performance.
圖10(a)由實線所示的圖表，是表示本發明的第1實施例的滾筒式洗衣乾衣機S所使用的循環泵24的旋轉速度與洗淨比的關係的圖表，圖10(a)由虛線所示的值，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)。 Fig. 10 (a) is a graph showing the relationship between the rotational speed of the circulation pump 24 and the washing ratio used in the drum-type washer-dryer S of the first embodiment of the present invention, as shown by a solid line diagram, Fig. 10 (a) The value indicated by the broken line is the value of the washing ratio (washing ratio = 1.11) indicating the operation of the conventional drum type washer-dryer.
又，圖10(b)由實線所示的圖表，是表示本 發明的第1實施例的滾筒式洗衣乾衣機S所使用的循環泵24的旋轉速度與蛇腹管22的洗滌水的循環流量的關係的圖表，圖10(b)由虛線所示的值，是表示以往的滾筒式洗衣乾衣機所使用的循環泵的旋轉速度與循環流量的關係的圖表。如圖10(b)所示，本實施例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。 Moreover, FIG. 10(b) is a graph shown by a solid line, indicating A graph showing the relationship between the rotational speed of the circulation pump 24 used in the drum-type washer-dryer S of the first embodiment of the present invention and the circulating flow rate of the washing water of the bellows 22, and FIG. 10(b) is a value indicated by a broken line. It is a graph showing the relationship between the rotation speed of the circulation pump used in the conventional drum type washer-dryer and the circulation flow rate. As shown in Fig. 10 (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10(a)所示，愈提高循環泵旋轉速度(愈增大循環流量)使洗淨比(洗淨性能)愈提昇。用循環泵旋轉速度在3000/min可獲得與以往的滾筒式洗衣機同等的洗淨比(洗淨性能)。又，循環泵旋轉速度在4000r/min附近洗淨比(洗淨性能)的上昇飽和。 As shown in Fig. 10 (a), the higher the circulation pump rotation speed (the larger the circulation flow rate), the higher the washing ratio (washing performance). The washing ratio (cleaning performance) equivalent to that of the conventional drum type washing machine can be obtained by using the circulating pump rotation speed at 3000/min. Further, the circulation speed of the circulation pump was saturated at a washing ratio (cleaning performance) of around 4000 r/min.
因此，循環泵旋轉速度是3000r/min以上4000r/min以下為期望。將循環泵旋轉速度設成未滿3000r/min時，洗淨比(洗淨性能)比以往的滾筒式洗衣機更下降而不理想。又，即使將循環泵旋轉速度設成比4000r/min更大，洗淨比(洗淨性能)的上昇雖只有些微，可是因為消耗電力大增而不理想。又，參照圖10(b)，換言之循環泵24的循環流量在36L/min以上52L/min以下為期望。 Therefore, it is desirable that the circulation pump rotation speed is 3000 r/min or more and 4000 r/min or less. When the circulation pump rotation speed is set to less than 3000 r/min, the washing ratio (cleaning performance) is lower than that of the conventional drum type washing machine. Further, even if the circulation pump rotation speed is set to be larger than 4000 r/min, the increase in the washing ratio (washing performance) is only slightly small, but it is not preferable because the power consumption is greatly increased. Further, referring to Fig. 10 (b), in other words, the circulation flow rate of the circulation pump 24 is desirably 36 L/min or more and 52 L/min or less.
由以上，根據滾筒式洗衣乾衣機S，驗證到將循環流量設定在36L/min以上，能發揮以往以上的洗滌性能。 From the above, according to the drum-type washer-dryer S, it was verified that the circulation flow rate was set to 36 L/min or more, and the above-described washing performance was exhibited.
此外，前述實施例的凹陷部2f(參照圖2及 圖3(a))的容積，是設定在2.5L。這是循環泵24的流量為52L/min時，為了確保水量而在進行連續運轉的循環泵24的吸入側不會捲入空氣。從吐出埠44到噴嘴27a的流路容積是0.35L，循環泵24驅動洗滌水從吐出埠44到達噴嘴27a的時間為0.4秒，從噴嘴27a吐出的洗滌水灑水到洗滌物而回到凹陷部2f的時間為2.5秒，合計在2.9秒鐘需要的水量為2.5L。為了確保貯水該2.5L的水量的容積，而在外槽2的底側內周面將凹狀的凹陷部2f設置成朝外槽2的軸向延伸存在。該凹陷部2f的深側L最大250mm。深度H最大50mm。進一步增大深側L、深度H時必須加大外槽2的深側、外槽2與底座1h的距離，而使筐體1的深側、高度變大。隨著這樣的情況滾筒式洗衣乾衣機S的設置性惡化。因此，為了將凹陷部2f的容積設成2.5L以上，寬幅Wk必須成為200mm以上。寬幅Wk可不會撞到阻尼器5固定部地擴大，且外槽2的直徑愈大可愈寬。本實施例的情況，相對於外槽2的內徑(φ570mm)的寬幅Wk的比例在35%。因此，相對於外槽2的內徑只要將寬幅Wk設定在35%以上，便可將凹陷部2f的容積設在2.5L以上。 In addition, the recessed portion 2f of the foregoing embodiment (refer to FIG. 2 and The volume of Fig. 3(a)) is set at 2.5L. When the flow rate of the circulation pump 24 is 52 L/min, air is not caught in the suction side of the circulation pump 24 that performs continuous operation in order to secure the amount of water. The flow path volume from the discharge port 44 to the nozzle 27a is 0.35 L, and the time during which the circulation pump 24 drives the wash water from the discharge port 44 to the nozzle 27a is 0.4 seconds, and the wash water discharged from the nozzle 27a is sprinkled with water to the laundry to return to the depression. The time of the portion 2f is 2.5 seconds, and the total amount of water required for 2.9 seconds is 2.5L. In order to secure the volume of the water amount of 2.5 L, the concave recessed portion 2f is provided to extend in the axial direction of the outer tub 2 on the inner peripheral surface of the bottom side of the outer tub 2. The deep side L of the depressed portion 2f is at most 250 mm. The depth H is up to 50mm. When the deep side L and the depth H are further increased, the distance between the deep side of the outer tank 2 and the outer tank 2 and the base 1h must be increased, and the depth and height of the casing 1 can be increased. With such a situation, the setting property of the drum type washing and drying machine S deteriorates. Therefore, in order to set the volume of the depressed portion 2f to 2.5 L or more, the wide width Wk must be 200 mm or more. The wide width Wk can be enlarged without hitting the fixed portion of the damper 5, and the larger the diameter of the outer groove 2, the wider the width. In the case of this embodiment, the ratio of the width Wk with respect to the inner diameter (φ570 mm) of the outer tub 2 is 35%. Therefore, the volume of the recessed portion 2f can be set to 2.5 L or more with respect to the inner diameter of the outer tub 2 as long as the wide width Wk is set to 35% or more.
由以上，根據滾筒式洗衣乾衣機S，循環流量為52L/min以下的設定時，將被設置在循環泵24的吸入側的凹陷部2f的容積設在2.5L以上，可確保水量使空氣不會被捲入循環泵24的吸入側，而可進行循環泵24的連續運轉。又，相對於外槽2的內徑只要將凹陷部2f的寬 幅Wk設定在35%以上，將可不變更筐體1的大小可降凹陷部2f的容積設定在2.5L以上，而可防止滾筒式洗衣乾衣機S的設置性的惡化。 In the above-described setting, when the circulation flow rate is 52 L/min or less, the volume of the recessed portion 2f provided on the suction side of the circulation pump 24 is set to 2.5 L or more, and the amount of water can be ensured. The continuous operation of the circulation pump 24 can be performed without being caught in the suction side of the circulation pump 24. Further, as long as the inner diameter of the outer groove 2 is as long as the width of the depressed portion 2f The width Wk is set to be 35% or more, and the volume of the recessed portion 2f can be set to 2.5 L or more without changing the size of the casing 1. The deterioration of the installability of the drum-type washer-dryer S can be prevented.
接著，一面參照圖11一面針對本發明的第2實施例的滾筒式洗衣乾衣機進行說明。與第1實施例的圖4(a)不同的點，是並列連接排水口21至入水埠23a之間的蛇腹管22。 Next, a drum-type washer-dryer according to a second embodiment of the present invention will be described with reference to Fig. 11 . The point different from FIG. 4(a) of the first embodiment is a bellows tube 22 that connects the drain port 21 to the water inlet port 23a in parallel.
在這樣的本實施例的滾筒式洗衣乾衣機S，減低排水口21至入水埠23a之間的流路阻抗，使從外槽2的排水口21回到循環泵24的洗滌水進一步變的良好，而可使洗滌水的循環流量提昇。而且，根據該滾筒式洗衣乾衣機S，與第1實施例的洗滌物同樣可讓相對於洗滌物的洗淨性能提昇。 In the drum-type washer-dryer S of this embodiment, the flow path impedance between the drain port 21 and the water inlet port 23a is reduced, and the washing water returning from the drain port 21 of the outer tub 2 to the circulation pump 24 is further changed. Good, and can increase the circulation flow rate of the wash water. Further, according to the drum-type washer-dryer S, the washing performance with respect to the laundry can be improved similarly to the laundry of the first embodiment.
又，藉由設置複數個排水口21至循環泵24的蛇腹管22使蛇腹管22流路容積增加，達成在循環泵24的吸入側需要的貯水的功能。藉此，與第1實施例同樣在循環泵24的吸入側所需要的2.5L以上的貯水，是即使縮小圖3(a)所示的凹陷部2f的容積也可確保。因此，由於不用改變圖1所示的筐體1的大小即可，所以可防止滾筒式洗衣乾衣機S的設置性的惡化。 Further, by providing a plurality of drain ports 21 to the bellows tube 22 of the circulation pump 24, the flow volume of the bellows tube 22 is increased, and the function of storing water required on the suction side of the circulation pump 24 is achieved. By the way, in the same manner as in the first embodiment, the water storage of 2.5 L or more required on the suction side of the circulation pump 24 can be ensured even if the volume of the recessed portion 2f shown in Fig. 3(a) is reduced. Therefore, since it is not necessary to change the size of the casing 1 shown in Fig. 1, it is possible to prevent the deterioration of the installability of the drum-type washer-dryer S.
