Description
本發明是關於滾筒式洗衣機。 The present invention relates to a drum type washing machine.
滾筒式洗衣機是滾筒的轉軸為大致水平,或將滾筒的開口部朝著斜向上方使轉軸傾斜,在將衣類投入該滾筒內之後,實施清洗過程、沖洗過程及脫水過程。清洗過程及沖洗過程是進行以低速旋轉滾筒藉此將停滯在滾筒下方的衣類捲起,隨後從滾筒的上方落下的翻轉動作。藉此翻轉動作,對衣類賦予機械的力進行清洗及沖洗。脫水步驟中,滾筒是以高速旋轉,藉此旋轉進行離心脫水將水分從衣類壓出。 The drum type washing machine is such that the rotating shaft of the drum is substantially horizontal, or the opening of the drum is inclined obliquely upward to tilt the rotating shaft, and after the clothes are put into the drum, the washing process, the rinsing process, and the dehydrating process are performed. The washing process and the rinsing process are a turning action of rotating the drum at a low speed to wind up the clothes stagnated under the drum and then falling from above the drum. By this turning action, the machine is given a mechanical force for cleaning and rinsing. In the dehydration step, the drum is rotated at a high speed, whereby the centrifugal dewatering is performed to press the moisture out of the clothes.
又,清洗過程中,以循環泵吸取洗衣槽(外槽)內的洗滌水沖灑於衣類。藉此將溶入洗劑的洗滌水完全地滲入衣類。如上述,滾筒式洗衣機與直立式洗衣機比較可一邊進行節水並確保清洗性能。 Further, during the cleaning process, the washing water in the washing tank (outer tank) is sucked into the clothes by the circulation pump. Thereby, the washing water dissolved in the lotion is completely infiltrated into the clothes. As described above, the drum type washing machine can save water while ensuring the cleaning performance as compared with the vertical type washing machine.
專利文獻1中,揭示有滾筒式洗衣機,具備:可儲水的水槽;具有可通水的孔並可旋轉配設在 上述水槽內的旋轉槽;在該水槽外部連通上述水槽具有的取水口與回水口的循環水路;設置在該循環水路的中途部的循環泵;及包含上述循環水路與上述循環泵所構成,將水槽內的水藉著上述循環泵的泵作用通過上述循環水路並吸入而從上述回水口朝上述水槽內吐出而循環的循環裝置(參閱申請專利範圍第1項)。 Patent Document 1 discloses a drum type washing machine including: a water tank that can store water; a water-permeable hole and a rotation-equipped a rotary groove in the water tank; a circulation water passage that communicates with the water intake port and the water return port of the water tank outside the water tank; a circulation pump provided in a middle portion of the circulation water passage; and the circulation water passage and the circulation pump The water in the water tank is circulated through the circulation water passage by the pump of the circulation pump, and is discharged from the water inlet port to the water tank to circulate (see the first item of the patent application).

〔專利文獻1〕日本特開2009-55999號公報 [Patent Document 1] Japanese Patent Laid-Open Publication No. 2009-55999
但是,旋轉槽的轉軸傾斜的滾筒式洗衣機與旋轉槽的轉軸朝垂直方向的直立式洗衣機比較因其構造上的理由儲水量變少。因此,習知的滾筒式洗衣機(例如,參閱專利文獻1),為以少的儲水量提升清洗效果而增長清洗時間時(清洗結束為止的清洗水與洗衣物的接觸時間增長時),一旦清洗水所洗出的皮脂等的汙物會有再次回到洗衣物的場合。並且,尤其是白色物或淺花樣的衣類等會因上述滾筒式洗衣機的重複洗衣次數而變黑的問題。 However, the drum type washing machine in which the rotating shaft of the rotary groove is inclined is smaller in water storage amount than the vertical washing machine in which the rotating shaft of the rotary groove is perpendicular to the structure. Therefore, the conventional drum type washing machine (for example, refer to Patent Document 1), when the washing time is increased by increasing the washing effect with a small amount of water storage (when the contact time of the washing water and the laundry is increased until the washing is completed), once cleaning Contaminants such as sebum washed out by water may return to the laundry again. Further, in particular, white matter or light-colored clothes and the like may become black due to the number of repeated washings of the above-described drum type washing machine.
另一方面,本發明人等重新發現將從外槽的底部到外槽的上部為止的循環流路的洗滌水的循環流量設定在預定值以上,即可防止洗衣物變黑。 On the other hand, the inventors of the present invention have found that the circulation flow rate of the washing water from the bottom of the outer tank to the upper portion of the outer tank is set to a predetermined value or more, thereby preventing the laundry from becoming black.
但是,較以往進一步增加循環流量以提升清洗性能的滾筒式洗衣機較以往有著高輸出之循環泵馬達的必要。並且,以上的滾筒式洗衣機會隨著循環泵馬達的高輸出化而在軸承產生電蝕的新課題。 However, it is necessary to further increase the circulation flow rate to improve the cleaning performance of the drum type washing machine than the conventional one having a high output circulating pump motor. Further, the above drum type washing machine has a new problem of causing electric corrosion in the bearing in accordance with the high output of the circulation pump motor.

第3(a)圖為第2圖的Ⅲ-Ⅲ剖面圖,形成於外槽底部的凹陷部的說明圖,第3(b)圖為形成於習知滾筒式洗衣乾燥機的外槽底部之凹陷部的說明圖。 Fig. 3(a) is a sectional view taken along line III-III of Fig. 2, an explanatory view of a depressed portion formed at the bottom of the outer groove, and Fig. 3(b) is a bottom portion of the outer groove formed in the conventional drum type washing and drying machine. An illustration of the depressed portion.
如第3(a)圖表示,在凹陷部2f的上部,形成有覆蓋凹陷部2f的寬度大致一半的從外槽2外圍壁的內周圍面連續的間隔壁W。間隔壁W是朝著相對於滾筒3脫水時的旋轉方向R成相對的方向沿著滾筒3的外圍面延伸出。排水口21及流入口18是形成在從凹陷部2f的寬方向中心朝著滾筒3的旋轉方向R偏移的位置。藉此在排水口21與流入口18的上部配置間隔壁W。 As shown in Fig. 3(a), a partition wall W continuous from the inner peripheral surface of the outer wall of the outer tub 2 is formed on the upper portion of the recessed portion 2f so as to cover substantially half the width of the recessed portion 2f. The partition wall W extends along the outer peripheral surface of the drum 3 in a direction opposite to the rotational direction R when the drum 3 is dehydrated. The drain port 21 and the inflow port 18 are formed at positions shifted from the center in the width direction of the recess portion 2f toward the rotation direction R of the drum 3. Thereby, the partition wall W is disposed in the upper portion of the drain port 21 and the inflow port 18.
凹陷部2f在脫水時藉著滾筒3旋轉產生的離心力,水從滾筒3的貫穿孔(省略圖示)朝著外槽2的內周圍面側排出時,阻止朝著與滾筒3的旋轉方向R相同方向流動的水而導入排水口21。間隔壁W可發揮使進入凹陷部2f的水不再回到外槽2內的停滯的作用效果。 When the recessed portion 2f is discharged by the centrifugal force generated by the rotation of the drum 3 during the dehydration, when the water is discharged from the through hole (not shown) of the drum 3 toward the inner peripheral surface side of the outer tub 2, the rotation direction R against the drum 3 is prevented. Water flowing in the same direction is introduced into the drain port 21. The partition wall W can exert an effect of stopping the stagnation of the water entering the recessed portion 2f from returning to the outer tub 2.
相對於第3(b)圖表示習知滾筒式洗衣乾燥機之凹陷部2f的容積為1-1.5L左右,設定第3 (a)圖表示本實施形態相關之滾筒式洗衣乾燥機100的凹陷部2f的容積為2.5L以上。 The volume of the depressed portion 2f of the conventional drum type laundry dryer is about 1-1.5 L with respect to the third (b), and the third is set. (a) The drawing shows that the volume of the recessed portion 2f of the drum type laundry dryer 100 according to the present embodiment is 2.5 L or more.
亦即,從第3(a)圖表示的凹陷部2f與第3(b)圖表示的凹陷部2f的對比可明確得知,本實施形態的凹陷部2f在外槽2的周圍方向形成為寬幅。該凹陷部2f也可設定成為外槽2之內徑的35%以上的寬度。 In other words, it is clear from the comparison between the depressed portion 2f shown in Fig. 3(a) and the depressed portion 2f shown in Fig. 3(b) that the depressed portion 2f of the present embodiment is formed wide in the circumferential direction 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,滾筒式洗衣乾燥機100較習知的滾筒式洗衣乾燥機增大外槽2的儲水量。藉此凹陷部2f的擴大,可提升後述之循環泵的轉速,將大流量的洗滌水吸入循環泵內,增大循環流量,其結果,衣類的洗淨效果可較習知的更為提升。 Thereby, the drum type laundry dryer 100 increases the water storage amount of the outer tub 2 as compared with the conventional drum type washer dryer. By the expansion of the recessed portion 2f, the number of revolutions of the circulation pump to be described later can be increased, and a large amount of washing water can be sucked into the circulation pump to increase the circulation flow rate. As a result, the washing effect of the clothes can be improved more conventionally.
接著參閱的第4(a)圖是表示從第1圖的滾筒式洗衣乾燥機的外槽底部朝向循環泵的循環流路的上視圖,第4(b)圖是表示從習知滾筒式洗衣乾燥機的外槽底部朝向循環泵的循環流路的上視圖。 4(a) is a top view showing a circulation flow path from the bottom of the outer tank of the drum type washing and drying machine of Fig. 1 toward the circulation pump, and Fig. 4(b) is a view showing the conventional drum type laundry. The top view of the outer tank bottom of the dryer faces the circulation flow path of the circulation pump.
如第4(a)圖表示,本實施形態的排水口21的接頭21a與蛇腹管22的連接部是形成從排水口21朝向左側突出。並且,蛇腹管22的一端是與接頭21a連接,蛇腹管22的另一端則是與循環泵24的進水埠23a連接。 As shown in Fig. 4(a), the joint portion of the joint 21a of the drain port 21 of the present embodiment and the bellows tube 22 is formed to protrude 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.
本實施形態的蛇腹管22是構成循環流路的一部份,蛇腹管22的內徑為35mm以上,並以設定 在37~50mm左右為佳。附帶一提,該蛇腹管22的內徑是以蛇腹的山徑(蛇腹的狹窄部的內徑)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 35 mm or more, and is set. It is preferably around 37~50mm. Incidentally, 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的長度為400mm以下,以設定在150~300mm左右為佳。附帶一提,蛇腹管22的長度是以從接頭21a的出口延伸至循環泵24的進水埠23a的入口為止之間的蛇腹管22的長度來規定。 Further, the length of the bellows tube 22 is 400 mm or less, and it is preferably set to about 150 to 300 mm. Incidentally, the length of the bellows 22 is defined by the length of the bellows tube 22 extending from the outlet of the joint 21a to the inlet of the inlet bowl 23a of the circulation pump 24.
如上述,本實施形態中,蛇腹管22是從橫向並從循環泵24側連接於接頭21a的出口,因此可縮短從接頭21a到循環泵24的進水埠23a的入口為止的長度,可減小流路阻力。又,設位於循環泵24上游側之蛇腹管22的內徑為較通常大的35mm以上,對於此點也可降低流路阻力。因此,詳細雖在以後說明,但可藉循環泵24轉速的提升,吸入大流量的洗滌水,可使其在滾筒3內循環。 As described above, in the present embodiment, since the bellows tube 22 is connected to the outlet of the joint 21a from the side of the circulation pump 24 in the lateral direction, the length from the joint 21a to the inlet of the water inlet port 23a of the circulation pump 24 can be shortened, and the length can be reduced. Small flow path resistance. Further, the inner diameter of the bellows tube 22 located on the upstream side of the circulation pump 24 is 35 mm or more larger than usual, and the flow path resistance can also be reduced at this point. Therefore, although it will be described later in detail, the large-flow washing water can be sucked in by the increase in the number of revolutions of the circulation pump 24, and can be circulated in the drum 3.
另外習知的滾筒式洗衣乾燥機的接頭21a是如第4(b)圖表示,形成朝向後側突出。並且,在接頭21a與進水埠23a之間延伸的習知的蛇腹管22a的長度為460mm左右,該習知蛇腹管22a的內徑為30mm左右。 Further, the joint 21a of the conventional drum type laundry dryer is formed as shown in Fig. 4(b) and protrudes 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.
第4(a)及(b)圖中,符號23b為循環泵24的出水埠,符號44是朝向外槽殼體2d的後述之循環流路27(參閱第8(a)圖)吐出水的吐出埠,符號45是將水從循環泵24送入外槽2(凹陷部2f)內 的吐出埠。 In the fourth (a) and (b), reference numeral 23b denotes a water discharge port of the circulation pump 24, and reference numeral 44 denotes a circulation flow path 27 (see Fig. 8(a)) which will be described later, which faces the outer tank casing 2d. Spit 埠, symbol 45 is to send water from the circulation pump 24 into the outer tank 2 (recessed portion 2f) Spit out.
再回到第2圖,在外槽2的後部端面的最下部設有防氣閥2e。在防氣閥2e的下部設有與外槽2(凹陷部2f)連通的孔2e1,以管35連接防氣閥2e的上部與水位感測器34,檢測外槽2內的水位。附帶地,習知的滾筒式洗衣乾燥機是在排水口21的後部上方設有防氣閥2e。循環水是從排水口21通過防氣閥2e的下方流向蛇腹管22a(參閱第4(b)圖)。由於蛇腹管22a的內徑較本實施形態的蛇腹管22(參閱第4(a)圖)的內徑狹窄,因此循環流量一旦增大時會使防氣閥2e的孔2e1下部的流速變大,而根據伯努利的定理有使得防氣閥2e內的壓力降低不能正確檢測外槽2內的水位的問題。本實施形態中,循環水是從排水口21向左側流動(參閱第4(a)圖),可減小連通孔2e1部的流速,可正確地檢測外槽2內的水位。 Returning to Fig. 2, an anti-gas valve 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 an upper portion of the air trap 2e and the water level sensor 34 are connected by a tube 35, and the water level in the outer tub 2 is detected. Incidentally, the conventional drum type laundry dryer is provided with an air trap 2e above the rear portion of the drain port 21. The circulating water flows from the drain port 21 through the air trap 2e to the bellows tube 22a (see Fig. 4(b)). Since the inner diameter of the bellows tube 22a is narrower than the inner diameter of the bellows tube 22 (see Fig. 4(a)) of the present embodiment, the flow rate of the lower portion of the hole 2e1 of the air trap 2e becomes large as the circulation flow rate increases. According to Bernoulli's theorem, there is a problem that the pressure in the anti-gas valve 2e is lowered and the water level in the outer tank 2 cannot be correctly detected. In the present embodiment, the circulating water flows from the drain port 21 to the left side (see Fig. 4(a)), and the flow velocity of the communicating hole 2e1 portion can be reduced, and the water level in the outer tub 2 can be accurately detected.
在外槽2與底座1h之間,設有循環泵24、濾箱23、排水閥25。濾箱23為在前側具有開口部的圓筒狀,內部裝設有可拆裝的濾器(省略圖示),捕集洗滌水中的異物或毛屑。濾箱23開設有設置在下部前面殼體1f的門1g,轉動把手23d可容易使濾器(省略圖示)脫著。該濾箱23是呈前側較高的傾斜。 A circulation pump 24, a filter box 23, and a drain valve 25 are provided between the outer tank 2 and the base 1h. The filter case 23 has a cylindrical shape having an opening on the front side, and a detachable filter (not shown) is attached inside to collect foreign matter or shavings in the washing water. The filter box 23 is provided with a door 1g provided in the lower front casing 1f, and the rotating handle 23d can easily disengage the filter (not shown). The filter box 23 is inclined at a higher front side.
關於以循環泵24為中心的洗滌水的循環系在後詳 細說明。 The circulation of the washing water centered on the circulation pump 24 is detailed later. Detailed description.
符號29為乾燥管路,配置在框體1的背面內側。該乾燥管路29是以橡膠製的蛇腹管29a連接在設置於外槽2後部的吸氣口。在乾燥管路29內設有水冷除溼機構(未圖示)。 Reference numeral 29 is a drying duct which is disposed inside the back surface of the casing 1. The drying duct 29 is connected to an air inlet provided at the rear of the outer tank 2 by a rubber bellows tube 29a. A water-cooling dehumidification mechanism (not shown) is provided in the drying line 29.
附帶地,在乾燥運轉時,以未圖示的加熱器、風扇等將熱風吹入滾筒3內,將水份從衣類蒸發。變得高溫多溼的空氣被吸入乾燥管路29內,以上述的水冷除溼機構冷卻除溼成為低溫空氣,並以未圖示的加熱器加熱後吹入滾筒3內。並且,也可以使用熱泵來取代加熱器、水冷除濕機構。 Incidentally, during the drying operation, hot air is blown into the drum 3 by a heater, a fan or the like (not shown) to evaporate water from the clothes. The air that has become hot and humid is sucked into the drying duct 29, and is cooled and dehumidified by the water-cooling and dehumidifying means to become low-temperature air, and is heated by a heater (not shown) and then blown into the drum 3. Further, a heat pump may be used instead of the heater or the water-cooling dehumidification mechanism.
接著參閱的第5圖為第4(a)圖的循環泵及濾箱的部份放大圖。第6圖為第5圖的Ⅵ-Ⅵ剖視圖。 Next, Fig. 5 is a partial enlarged view of the circulation pump and the filter box of Fig. 4(a). Fig. 6 is a sectional view taken along line VI-VI of Fig. 5.
本實施形態的循環泵24為離心泵,如第5圖表示,具備泵殼42、葉輪(也稱為轉子)46、循環泵馬達47。 The circulation pump 24 of the present embodiment is a centrifugal pump. As shown in Fig. 5, the circulation pump 24 includes a pump casing 42, an impeller (also referred to as a rotor) 46, and a circulation pump motor 47.
泵殼42是具備與濾箱23一體成形的第1殼體42a及與該第1殼體42a連結的第2殼體42b所構成。 The pump casing 42 is configured to include a first casing 42a that is integrally formed with the filter casing 23 and a second casing 42b that is coupled to the first casing 42a.
第1殼體42a是以大致圓筒體所形成,在其內側配置有葉輪46。 The first casing 42a is formed of a substantially cylindrical body, and an impeller 46 is disposed inside the first casing 42a.
在第1殼體42a形成有吸入埠43、吐出埠44、吐 出埠45、進水埠23a及出水埠23b。 Inhalation crucible 43, discharge spout 44, and spit are formed in the first casing 42a. Exit 45, water inlet 23a and water outlet 23b.
吸入埠43為連結濾箱23與第1殼體42a的大致圓形的貫穿孔,與循環泵24的葉輪46同軸形成。 The suction port 43 is a substantially circular through hole that connects the filter case 23 and the first case 42a, and is formed coaxially with the impeller 46 of the circulation pump 24.
循環泵24是透過吸入埠43將進入第1殼體42a內的洗滌水,對應安裝於循環泵馬達47的轉軸48(參閱第6圖)的葉輪46的旋轉方向,朝向吐出埠44、45的其中之一吐出。 The circulation pump 24 passes the washing water that has entered the first casing 42a through the suction port 43, and corresponds to the rotation direction of the impeller 46 attached to the rotating shaft 48 (see FIG. 6) of the circulation pump motor 47, and faces the discharge ports 44 and 45. One of them spit out.
葉輪46從前面(第5圖的吸入埠43側)顯示為左旋轉(以後,有稱正旋轉),透過吐出埠44將洗滌水送出至後述的循環泵路27(參閱第8(a)圖)。更進一步詳細說明時,葉輪46正旋轉時,從吸入埠43流入的洗滌水是以葉輪46的離心力的泵作用被朝向第1殼體42a的內周圍壁推出。並且,洗滌水在第1殼體42a內一邊左旋轉並流動,和第1殼體42a的內周圍壁與葉輪46的徑向間隙變窄的間隔壁(省略圖示)碰撞改變流動方向而從吐出埠44流出。 The impeller 46 is shown as a left rotation (hereinafter referred to as a positive rotation) from the front side (the side of the suction port 43 in Fig. 5), and the washing water is sent to the circulation pump path 27 to be described later through the discharge port 44 (see Fig. 8(a) ). More specifically, when the impeller 46 is rotating, the washing water flowing in from the suction weir 43 is pushed out toward the inner peripheral wall of the first casing 42a by the pumping action of the centrifugal force of the impeller 46. In addition, the washing water rotates leftward in the first casing 42a, and flows, and the partition wall (not shown) in which the inner peripheral wall of the first casing 42a and the impeller 46 are narrowed in a radial direction collides and changes the flow direction. Spit out 埠44 out.
葉輪46一旦右旋轉(以後,有稱逆旋轉)時,和第1殼體42a的內周圍壁與葉輪46的徑向間隙變窄的間隔壁(省略圖示)碰撞而改變流動方向,使得洗滌水從吐出埠45流出。如上述,改變循環泵24的旋轉方向,不需使用特別的流路切換機構即可改變循環泵24的吐出方向。 When the impeller 46 rotates to the right (hereinafter, referred to as reverse rotation), the inner peripheral wall of the first casing 42a collides with a partition wall (not shown) in which the radial gap of the impeller 46 is narrowed to change the flow direction, so that the washing is performed. Water flows out of the spit. As described above, by changing the rotation direction of the circulation pump 24, the discharge direction of the circulation pump 24 can be changed without using a special flow path switching mechanism.
第6圖為第5圖的Ⅵ-Ⅵ剖視圖。 Fig. 6 is a sectional view taken along line VI-VI of Fig. 5.
如第6圖表示,第2殼體42b是以直徑大於第1殼體42a的有底大致圓筒體所形成。該第2殼體42b是將其底側朝向第1殼體42a配置。第二殼體42b是設在第1殼體42a與循環泵馬達47之間,藉此將葉輪46水密性配置在第1殼體42a的內側。第6圖中,符號S1為水密性封閉第1殼體42a與第2殼體42b之間的O環。 As shown in Fig. 6, the second casing 42b is formed of a substantially cylindrical body having a diameter larger than that of the first casing 42a. The second casing 42b is disposed such that its bottom side faces the first casing 42a. The second casing 42b is provided between the first casing 42a and the circulation pump motor 47, whereby the impeller 46 is disposed in a watertight manner inside the first casing 42a. In Fig. 6, reference numeral S1 denotes an O-ring between the first casing 42a and the second casing 42b in a watertight manner.
又,在第2殼體42b的底中心,形成有接下來說明的循環泵馬達47的轉軸48插穿的插穿孔42c。第6圖中,符號S2為水密性封閉插穿於插穿孔42c的轉軸48與第2殼體42b的密封材。第6圖中,符號23為濾箱,符號23a為循環泵24的進水埠,符號23b為循環泵24的出水埠,符號23c為濾器。 Further, at the bottom center of the second casing 42b, an insertion hole 42c through which the rotation shaft 48 of the circulation pump motor 47 described later is inserted is formed. In Fig. 6, reference numeral S2 denotes a sealing material that is watertightly inserted through the rotating shaft 48 of the insertion hole 42c and the second casing 42b. In Fig. 6, reference numeral 23 is a filter box, reference numeral 23a is a water inlet port of the circulation pump 24, reference numeral 23b is a water discharge port of the circulation pump 24, and reference numeral 23c is a filter.
循環泵馬達47是如第6圖表示,在馬達箱51內,主要是具備設置在轉軸48周圍的轉子50a,及設置在該轉子50a外圍側的定子50b所構成。本實施形態的循環泵馬達47為無刷馬達,其轉軸48可朝正旋轉及逆旋轉的兩方向旋轉。 The circulation pump motor 47 is shown in Fig. 6. The motor casing 51 mainly includes a rotor 50a provided around the rotating shaft 48 and a stator 50b provided on the outer peripheral side of the rotor 50a. The circulation pump motor 47 of the present embodiment is a brushless motor, and the rotation shaft 48 is rotatable in both the forward rotation and the reverse rotation.
馬達箱51是連接一對有底圓筒51a、51b的開口側彼此所形成。 The motor case 51 is formed by connecting the opening sides of the pair of bottomed cylinders 51a and 51b.
配置使轉軸48通過馬達箱51的中心軸,並使得安裝著葉輪46的一端側從馬達箱51的內側朝外側突出。 The rotation shaft 48 is disposed to pass through the center shaft of the motor case 51, and the one end side on which the impeller 46 is attached protrudes outward from the inner side of the motor case 51.
附帶地,朝馬達箱51的外側突出的轉軸48的直徑是形成比配置在馬達箱51內側的轉軸48的直徑還細。並且,細直徑的轉軸48的部份是透過密封材S2貫穿第2殼體42b的插穿孔42c,並在貫穿之其前端部安裝有如上述的葉輪46。 Incidentally, the diameter of the rotating shaft 48 that protrudes toward the outside of the motor case 51 is formed to be smaller than the diameter of the rotating shaft 48 disposed inside the motor case 51. Further, a portion of the shaft 48 having a small diameter penetrates the insertion hole 42c of the second casing 42b through the seal member S2, and the impeller 46 as described above is attached to the tip end portion thereof.
軸承49是分別在形成馬達箱51的有底圓筒51a、51b的底部中心配置一對可支撐轉軸48。 The bearing 49 is provided with a pair of supportable rotating shafts 48 at the center of the bottom of the bottomed cylinders 51a, 51b forming the motor case 51, respectively.
本實施形態的軸承49為滾動軸承,具備內輪49a、外輪49b及組裝於該等內輪49a與外輪49b之間的複數滾動體49c。 The bearing 49 of the present embodiment is a rolling bearing, and includes an inner ring 49a, an outer ring 49b, and a plurality of rolling elements 49c assembled between the inner ring 49a and the outer ring 49b.
並且,本實施形態的循環泵馬達47為確保後述之預定的循環流量,形成可以2300~4200rpm的轉速旋轉。又,循環泵馬達47的輸出是以30W以上為佳,並以100W以上更佳。 Further, the circulation pump motor 47 of the present embodiment is configured to be capable of rotating at a number of revolutions of 2,300 to 4,200 rpm in order to secure a predetermined circulation flow rate to be described later. Further, the output of the circulation pump motor 47 is preferably 30 W or more, and more preferably 100 W or more.
但是,本實施形態的循環泵馬達47是如上述,與使用於習知滾筒式洗衣機(例如,參閱專利文獻1)的循環泵馬達比較,使用其輸出更大的馬達。藉此透過對應轉子50a及定子50b的靜電容量增加量的激勵,在轉軸48形成數V程度的電位。亦即,形成使轉軸48、軸承49及馬達箱51循環的循環電流,在轉軸48產生軸電流。其結果,支撐轉軸48的軸承49的內部產生放電而會在軸承49導致電蝕。 However, the circulation pump motor 47 of the present embodiment uses a motor having a larger output than the circulation pump motor used in the conventional drum type washing machine (see, for example, Patent Document 1) as described above. Thereby, a potential of several V is formed on the rotating shaft 48 by the excitation corresponding to the increase in the electrostatic capacity of the rotor 50a and the stator 50b. That is, a circulating current that circulates the rotating shaft 48, the bearing 49, and the motor case 51 is formed, and a shaft current is generated in the rotating shaft 48. As a result, a discharge is generated inside the bearing 49 supporting the rotating shaft 48, which causes electrical corrosion in the bearing 49.
相對於此本發明的循環泵馬達47具有用 於防止轉軸48之軸電流產生的電絕緣機構60。具體而言,電絕緣機構60是具有施以電絕緣處理後的轉軸48所構成。在此所謂「施以電絕緣處理後的轉軸」是意味著至少在與軸承49接觸的轉軸48的表面具有絕緣性的包覆膜,但包含著轉軸48本身是以絕緣性材料所形成,及在軸承49、49之間延伸的轉軸48的途中設置由絕緣性材料所成的耦合部份之意。再者,作為絕緣性包覆膜的材料及絕緣性材料可舉例如CrN、TiN、TiAlN、TiCN、TiC、WC/C、AlTiC等的硬質陶瓷。附帶地,該等材料所成的絕緣性的包覆膜可以濺射法等所形成。 In contrast to the circulation pump motor 47 of the present invention An electrical insulation mechanism 60 for preventing the generation of shaft current from the shaft 48. Specifically, the electrical insulating mechanism 60 is configured to have a rotating shaft 48 that is subjected to electrical insulation treatment. Here, the "rotating shaft after the electric insulating treatment" means a coating film having an insulating property at least on the surface of the rotating shaft 48 that is in contact with the bearing 49, but the rotating shaft 48 itself is formed of an insulating material, and A coupling portion made of an insulating material is provided on the way of the rotating shaft 48 extending between the bearings 49, 49. Further, examples of the material and the insulating material of the insulating coating film include hard ceramics such as CrN, TiN, TiAlN, TiCN, TiC, WC/C, and AlTiC. Incidentally, an insulating coating film made of these materials can be formed by a sputtering method or the like.
以上的電絕緣機構60電截斷上述循環電流的流動,防止轉軸48的軸電流的產生。因此,滾筒式洗衣乾燥機100可防止循環泵馬達47之軸承49的電蝕。 The above electrical insulating mechanism 60 electrically cuts off the flow of the circulating current to prevent the generation of the shaft current of the rotating shaft 48. Therefore, the drum type laundry dryer 100 can prevent the electric corrosion of the bearing 49 of the circulation pump motor 47.
又,本實施形態的電絕緣機構60是如上述,雖設定具有施以電絕緣處理後的轉軸48所構成,但是本發明只要可防止轉軸48的軸電流的產生則不為此所限定。 Further, although the electric insulating mechanism 60 of the present embodiment is configured to have the rotating shaft 48 subjected to the electrical insulating treatment as described above, the present invention is not limited thereto as long as the generation of the shaft current of the rotating shaft 48 can be prevented.
亦即,雖然未圖示,但是電絕緣機構可以具備有施以電絕緣處理後的滾動體49c的軸承49所構成。在此所謂「施以電絕緣處理後的滾動體」是意味著在滾動體49c的表面具有絕緣性的包覆膜,但包含 滾動體49c本身以絕緣性材料形成之意。作為絕緣性包覆膜的材料及絕緣性材料,可舉例如上述的硬質陶瓷。 That is, although not shown, the electrical insulating mechanism may be constituted by a bearing 49 having a rolling element 49c subjected to electrical insulation treatment. Here, the "rolling element after the electric insulating treatment is applied" means a coating film having an insulating property on the surface of the rolling element 49c, but includes The rolling elements 49c themselves are formed of an insulating material. Examples of the material of the insulating coating film and the insulating material include the above-described hard ceramics.
並且,雖然未圖示,但電絕緣機構可以在內輪49a及外輪49b中的至少一方具有已施以電絕緣處理的軸承49所構成。 Further, although not shown, the electric insulating mechanism may be constituted by a bearing 49 to which at least one of the inner ring 49a and the outer ring 49b is subjected to electrical insulation treatment.
並且,雖然未圖示,但電絕緣機構可以具有透過環狀的絕緣性材料連接有底圓筒51a、51a彼此的馬達箱51所構成。 Further, although not shown, the electric insulating mechanism may be constituted by a motor case 51 in which the bottom cylinders 51a and 51a are connected to each other via an annular insulating material.
第7圖是表示第1圖的滾筒式洗衣乾燥機之循環機構的循環泵及循環流路的透視圖。 Fig. 7 is a perspective view showing a circulation pump and a circulation flow path of a circulation mechanism of the drum type washing and drying machine of Fig. 1.
如第7圖表示,吐出埠44是透過蛇腹管41與設置在外槽殼體2d的內側周圍壁之後述的循環流路27(參閱第8(a)圖)連結。並且,該蛇腹管41及循環流路27是與蛇腹管22一起,構成從外槽2的底部到達外槽2的上部為止的循環流路。循環流路27是與設置在外槽殼體2d上方內側的後述噴嘴27a(參閱第8(a)圖)連接。 As shown in Fig. 7, the discharge port 44 is connected to the circulation flow path 27 (see Fig. 8(a)), which will be described later, through the bellows tube 41 and the inner peripheral wall of the outer tank case 2d. Further, the bellows tube 41 and the circulation flow path 27 constitute a circulation flow path from the bottom of the outer tank 2 to the upper portion of the outer tank 2 together with the bellows tube 22. The circulation flow path 27 is connected to a later-described nozzle 27a (see Fig. 8(a)) provided inside the outer tank casing 2d.
吐出埠45是透過蛇腹管40與接頭18a連接。該接頭18a被設置在鄰接外槽2底部的凹陷部2f(參閱第3(a)圖)所形成的流入口18。 The spout 45 is connected to the joint 18a through the bellows 40. The joint 18a is provided at an inflow port 18 formed by a recessed portion 2f (see Fig. 3(a)) adjacent to the bottom of the outer tub 2.
在關閉上述排水閥25(參閱第2圖)的狀態下,使循環泵24的循環泵馬達47正旋轉時,外 槽2內的洗滌水是從排水口21(參閱第3(a)圖)通過蛇腹管22,以濾箱23內的濾器(省略圖示)除去異物。之後,洗滌水從上述的吸入埠43(參閱第5圖)進入泵殼42(第5圖的箭頭F),並從吐出埠44吐出。並且,洗滌水是如上述,被送入第8(a)圖表示的循環流路27而從噴嘴27a朝著滾筒3(參閱第2圖)灑水。 When the circulation pump 25 of the circulation pump 24 is rotated while the drain valve 25 (see Fig. 2) is closed, the outer circulation is external. The washing water in the tank 2 is passed through the bellows 22 from the drain port 21 (see Fig. 3(a)), and the foreign matter is removed by a filter (not shown) in the filter box 23. Thereafter, the washing water enters the pump casing 42 (arrow F in Fig. 5) from the above-described suction port 43 (see Fig. 5), and is discharged from the discharge port 44. Then, the washing water is sent to the circulation flow path 27 shown in Fig. 8(a) as described above, and water is sprinkled from the nozzle 27a toward the drum 3 (see Fig. 2).
使循環泵24的循環泵馬達47逆旋轉時,外槽2內的洗滌水是從排水口21(參閱第3(a)圖)通過蛇腹管22,以濾箱23內的濾器(省略圖示)除去異物。之後,洗滌水從上述的吸入埠43(參閱第5圖)進入泵殼42,並從吐出埠45吐出,透過蛇腹管40及接頭18a回到外槽2內。並且,開啟上述的排水閥25(參閱第2圖)時,外槽2內的洗滌水通過濾箱23內的濾器(省略圖示),從排水管26排水至機外。 When the circulation pump motor 47 of the circulation pump 24 is reversely rotated, the washing water in the outer tank 2 passes through the bellows 22 from the drain port 21 (see Fig. 3(a)), and the filter in the filter box 23 (not shown) Remove foreign matter. Thereafter, the washing water enters the pump casing 42 from the above-described suction port 43 (see Fig. 5), is discharged from the discharge port 45, and is returned to the outer tub 2 through 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 passes through a filter (not shown) in the filter box 23, and is drained from the drain pipe 26 to the outside of the machine.
接著參閱的第8(a)圖是表示設置在外槽殼體的循環流路的透視圖,第8(b)圖是表示與循環泵及設置在外槽殼體的循環流路連接的蛇腹管的透視圖。 Next, referenced to Fig. 8(a) is a perspective view showing a circulation flow path provided in the outer tank casing, and Fig. 8(b) is a view showing the bellows pipe connected to the circulation pump and the circulation flow path provided in the outer tank casing. perspective.
如第8(a)及(b)圖表示,其一端被連接於循環泵24的吐出埠44的蛇腹管41是將其另一端連接在循環流路27的入口埠2g。該入口埠2g是如第 8(b)圖表示,形成於外槽殼體2d的外圍面。 As shown in Figs. 8(a) and 8(b), the bellows tube 41 whose one end is connected to the discharge port 44 of the circulation pump 24 is the inlet port 2g that connects the other end thereof to the circulation flow path 27. The entrance 埠 2g is like the first 8(b) shows a peripheral surface formed on the outer tank casing 2d.
本實施形態的循環流路27是如第8(a)表示,以一體成形於樹脂製之外槽殼體2d的內側周圍壁的管狀通路所構成。該循環流路27是沿著外槽殼體2d的開口形成,連接於形成在外槽殼體2d上部的噴嘴27a。該循環流路27的剖面形狀尤其不加以限制,可以是圓形、橢圓形、多角形等。循環流路27的剖面積換算成圓形是以相當於直徑25mm以上的為佳。 The circulation flow path 27 of the present embodiment is constituted by a tubular passage integrally formed on the inner peripheral wall of the groove case 2d made of resin, as shown in Fig. 8(a). The circulation flow path 27 is formed along the opening of the outer tank casing 2d, and is connected to the nozzle 27a formed in the upper portion of the outer tank casing 2d. The cross-sectional shape of the circulation flow path 27 is not particularly limited, and may be a circular shape, an elliptical shape, a polygonal shape or the like. The cross-sectional area of the circulation flow path 27 is preferably a circular shape equivalent to a diameter of 25 mm or more.
根據本實施形態的循環流路27,由於是設置在外槽殼體2d的內側周圍壁,因此和習知的例如設置在外槽殼體2d的外側周圍壁之氯乙烯管等所形成的不同,破損的可能性較為減少,且即使萬一破損時洗滌水也不會漏出至外槽2的外側。又,循環流路27是與外槽殼體2d一體成形,因此較習知少的零組件數即可。 Since the circulation flow path 27 of the present embodiment is provided on the inner peripheral wall of the outer tank casing 2d, it is different from the conventionally formed vinyl chloride pipe or the like provided on the outer peripheral wall of the outer tank casing 2d, and is damaged. The possibility is reduced, and even in the event of breakage, the washing water does not leak out to the outside of the outer tank 2. Further, since the circulation flow path 27 is integrally formed with the outer tank case 2d, the number of components which are less conventional can be used.
噴嘴27a是將從循環泵24的吐出埠44所吐出的洗滌水由外槽殼體2d的上部朝向滾筒3(參閱第2圖)內噴射之用。 The nozzle 27a is for ejecting the washing water discharged from the discharge port 44 of the circulation pump 24 from the upper portion of the outer tank casing 2d toward the drum 3 (see Fig. 2).
第9圖是連接於設置在外槽殼體的循環流路的噴嘴附近的部份放大透視圖。 Fig. 9 is a partially enlarged perspective view showing the vicinity of the nozzle which is connected to the circulation flow path provided in the outer tank casing.
如第9圖表示,噴嘴27a是使其開口形成為縫隙狀,可將洗滌水擴展成薄膜狀,朝著滾筒3(參閱第2圖)內的寬廣範圍灑水。又,由於洗滌水的循環流量 較以往增加,所以該噴嘴27a的縫隙寬度(間隙寬度)即使較以往寬廣也不會使噴射的力量減弱。因此,可以設縫隙寬度(間隙寬度)為3mm以上,可確實防止因毛屑等而導致噴嘴27a的阻塞。 As shown in Fig. 9, the nozzle 27a has its opening formed into a slit shape, and the washing water can be expanded into a film shape, and water can be sprayed toward a wide range in the drum 3 (see Fig. 2). Also, due to the circulating flow of washing water Since the gap width (gap width) of the nozzle 27a is wider than in the past, the force of the ejection is not weakened. Therefore, the slit width (gap width) can be set to 3 mm or more, and the clogging of the nozzle 27a due to shavings or the like can be surely prevented.
又,可以在外槽殼體2d形成鄰接於噴嘴27a而與循環流路27(參閱第8(a)圖)連通小孔H。洗滌水通過循環流路27從噴嘴27a噴射時,會從該小孔H朝向波紋管10的內側噴射洗滌水。並從該小孔H所噴射的洗滌水在波紋管10的內側從上部向下部流動時,可以使附著在波紋管10內側的毛屑等流掉。 Further, the outer tank casing 2d may be formed adjacent to the nozzle 27a and communicate with the circulation flow path 27 (see Fig. 8(a)). 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 inside of the bellows 10. When the washing water sprayed from the small hole H flows from the upper portion to the lower portion inside the bellows 10, the dust or the like adhering to the inner side of the bellows 10 can be discharged.

Further, the control device 38 displays the determined washing dose and running time on the display 14. Further, the water supply to the outer tank 2 has been described as the conductivity (hardness) and water temperature of the test water, but it is not limited thereto. For example, the conductivity (hardness) and water temperature of the water during the previous operation may be stored in advance in a storage unit (not shown) of the microcomputer.

The control device 38 controls the drum motor 4 to rotate the drum 3, controls the circulation pump 24 to have a predetermined flow rate (for example, 3800 rpm), and washes the washing water sucked by the drain port 21 from the nozzle 27a provided in the opening of the outer tub 2 toward the drum 3. The inside spits out and cleans the clothes. Then, when the predetermined time elapses, the control device 38 ends the washing and stirring step, and proceeds to step S17.
步驟17中,控制裝置38是執行排水步驟。控制裝置38將滾筒馬達4及循環泵24停止,開啟排水閥25進行外槽2內之清洗水的排水。水位感測器34持續監視排水中的外槽2內之洗滌水的水位。水位感測器34的檢測值一旦低於預定的水位時,控制裝 置38結束排水步驟,前進至步驟S18。 In step 17, control unit 38 is performing a draining step. The control device 38 stops the drum 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 34 continuously monitors the water level of the wash water in the outer tank 2 in the drain. When the detected value of the water level sensor 34 is lower than the predetermined water level, the control device is installed. The draining step 38 ends, and the process proceeds to step S18.
步驟18中,控制裝置38是執行脫水步驟。具體而言,控制裝置38開啟排水閥25的同時,控制滾筒馬達4並以高速旋轉滾筒3,進行衣類的離心脫水。並且,預定的時間經過時,控制裝置38停止滾筒馬達4,開啟排水閥25,結束洗滌行程(洗滌~清洗~脫水)。 In step 18, control unit 38 is performing the dehydration step. Specifically, the control device 38 opens the drain valve 25, controls the drum motor 4, and rotates the drum 3 at a high speed to perform centrifugal dewatering of the clothes. When the predetermined time elapses, the control device 38 stops the drum motor 4, opens the drain valve 25, and ends the washing course (washing-washing-dehydration).
正式清洗步驟(S8)的滾筒3的轉速是小於60rpm。設滾筒3的轉速小於60rpm,藉此將停滯在滾筒3內下方的衣類捲起進行從滾筒3內的上方落下的敲打洗滌。藉著以敲打洗滌施加於衣類的落下衝擊(機械力)獲得洗淨性能。 The rotation speed of the drum 3 of the main washing step (S8) is less than 60 rpm. The rotation speed of the drum 3 is set to be less than 60 rpm, whereby the clothes that have stagnated in the lower side of the drum 3 are wound up and subjected to tapping washing from the upper side in the drum 3. The washing performance was obtained by tapping the falling impact (mechanical force) applied to the clothes.
又,預洗滌攪拌步驟(S7)的滾筒3的轉速是成為60rpm以上。設滾筒3的轉速為60rpm以上,可藉著離心力將滾筒3內的衣類貼附於滾筒3的壁面方向。亦即,抑制衣類從滾筒3內的上方落下時施加的落下衝擊(機械力),可抑制「衣類的發硬」。一般滾筒式乾燥機是使衣類落下進行敲打洗滌,因此和直立式洗衣機比較衣類容易發硬,但根據本實施形態,因可抑制預洗滌攪拌步驟中的落下衝擊可使衣類不容易發硬。 Further, the number of revolutions of the drum 3 in the pre-washing stirring step (S7) 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 can be attached to the wall surface direction of the drum 3 by centrifugal force. In other words, the falling impact (mechanical force) applied when the clothes are dropped from the upper side in the drum 3 can be suppressed, and the "hardening of the clothes" can be suppressed. In general, the drum type dryer is such that the clothes are dropped and subjected to tapping washing. Therefore, the clothes are more likely to be harder than the vertical type washing machine. However, according to the present embodiment, the clothes can be prevented from being hardened by suppressing the falling impact in the pre-washing and stirring step.
另一方面,由於機械力的抑制,會有使洗淨性能降低之虞。針對此,將預洗滌攪拌步驟的循環 泵24的轉速成為2300rpm以上,使得循環流量較習知的滾筒式乾燥洗衣機更為增加。藉此,可將洗劑濃度高的洗滌水充分浸透至衣類,利用包含於洗劑的界面活性劑或輔助劑的作用將髒汙從衣類容易地除去。並且,滾筒3是以60rpm以上的轉速旋轉,雖是以其離心力使衣類通過浸漬衣類的洗滌水,但髒汙的一部份會從衣類被洗滌水通過衣類時的流體力所除去。 On the other hand, due to the suppression of mechanical force, there is a fear that the cleaning performance is lowered. For this, the cycle of the pre-washing agitation step The rotation speed of the pump 24 becomes 2300 rpm or more, so that the circulation flow rate is increased more than the conventional drum type dry washing machine. Thereby, the washing water having a high washing agent concentration can be sufficiently permeated into the clothes, and the dirt can be easily removed from the clothes by the action of the surfactant or the auxiliary agent contained in the lotion. Further, the drum 3 is rotated at a number of revolutions of 60 rpm or more, and the clothes are passed through the washing water of the immersion clothing by the centrifugal force, but a part of the dirt is removed from the fluid force when the clothes are washed by the washing water.
如上述,預洗滌攪拌步驟中,洗劑濃度高的洗滌水會充分浸透至衣類,並且藉離心力之流體力的作用,即使縮短正式洗滌攪拌步驟的時間(減小機械力)仍可確保洗淨性能。 As described above, in the pre-washing and stirring step, the washing water having a high concentration of the lotion is sufficiently saturated into the clothes, and by the action of the fluid force of the centrifugal force, the washing time can be ensured even if the time of the main washing and stirring step is shortened (reducing the mechanical force). performance.
接著,針對根據循環泵24的循環流量與洗淨性能的關係,使用第11(a)及(b)圖說明。 Next, the relationship between the circulation flow rate of the circulation pump 24 and the cleaning performance will be described using Figs. 11(a) and (b).
第11(a)圖是表示循環泵的循環流量與洗淨比的關係的圖表。附帶一提,洗淨比為供測試洗衣機的洗淨度與標準洗衣機的洗淨度的比,規定於日本工業規格『家電用電動洗衣機的性能測量方法(JISC9811)』。亦即,洗淨比越高,洗淨性能即越高。 Fig. 11(a) is a graph showing the relationship between the circulation flow rate of the circulation pump and the washing ratio. Incidentally, the ratio of the cleaning ratio to the degree of cleaning of the test washing machine and the washing degree of the standard washing machine is defined in the Japanese Industrial Standard "Measurement Method for Performance of Electric Washing Machines for Household Appliances (JISC9811)". That is, the higher the washing ratio, the higher the washing performance.
再者,第11(a)圖中,實線為本實施形態的滾筒式洗衣乾燥機100的圖表,虛線是表示將習知的滾筒式洗衣乾燥機以和本實施形態的滾筒式洗衣乾燥機100相同的攪拌時間運轉時的洗淨比的值(洗淨比 =1.11)。 Further, in the eleventh (a)th drawing, the solid line is a graph of the drum type washing and drying machine 100 of the present embodiment, and the broken line indicates a conventional drum type washing and drying machine and the drum type washing and drying machine of the present embodiment. The value of the washing ratio when running at the same stirring time of 100 (washing ratio) =1.11).
第11(b)圖是表示循環泵的轉速與循環流量的關係的圖表。 Fig. 11(b) is a graph showing the relationship between the number of revolutions of the circulation pump and the circulating flow rate.
並且,第11(b)圖中,實線為本實施形態的滾筒式洗衣乾燥機100的圖表,虛線是作為比較例的習知滾筒式洗衣乾燥機的圖表。附帶一提,如第11(b)圖表示,本實施形態相關之滾筒式洗衣乾燥機100是使用循環流量的最大值比習知滾筒式洗衣乾燥機大的循環泵。 Further, in the eleventh (b)th drawing, the solid line is a graph of the drum type washing and drying machine 100 of the present embodiment, and the broken line is a graph of a conventional drum type washing and drying machine as a comparative example. Incidentally, as shown in Fig. 11(b), the drum type laundry dryer 100 according to the present embodiment is a circulation pump which uses a larger maximum circulation flow rate than a conventional drum type laundry dryer.
如第11(a)圖表示,循環流量越多則越可提升洗淨比(洗淨性能)。在循環流量35L/min附近獲得與習知滾筒式洗衣乾燥機相同的洗淨比(洗淨性能)。並且,循環流量在60L/min附近則洗淨比(洗淨性能)的上升呈飽和。 As shown in Fig. 11(a), the more the circulating flow rate, the higher the washing ratio (cleaning performance). The same washing ratio (cleaning performance) as that of the conventional drum type laundry dryer was obtained in the vicinity of the circulating flow rate of 35 L/min. Further, when the circulating flow rate is around 60 L/min, the washing ratio (washing performance) is increased.
因此,循環流量是以在35L/min以上、60L/min以下為佳。循環流量低於35L/min時,洗淨比較習知的滾筒式洗衣乾燥機降低而不理想。並且,循環流量大於60L/min時,則洗淨比的上升極些微,但會增加循環泵24的耗費電力,因此不期待增加所需的循環流量以上。以上,雖針對循環流量已作說明,但本實施形態例的循環泵24參閱第11(b)圖時,循環泵的轉速成為2300rpm以上、3800rpm以下。 Therefore, the circulation flow rate is preferably 35 L/min or more and 60 L/min or less. When the circulation flow rate is lower than 35 L/min, it is not preferable to wash the conventional drum type laundry dryer. Further, when the circulation flow rate is more than 60 L/min, the increase in the washing ratio is extremely small, but the power consumption of the circulation pump 24 is increased. Therefore, it is not expected to increase the required circulating flow rate or more. In the above-described circulation pump 24 of the present embodiment, the number of revolutions of the circulation pump is 2,300 rpm or more and 3,800 rpm or less.
循環泵24的轉速在各步驟中可並非經常 成為一定,在上述2300rpm以上3800rpm以下的循環泵轉速的範圍是意味著各步驟的循環泵24的轉速的平均值包含在此範圍內。例如,在步驟S7(參閱第10圖)的預洗滌攪拌步驟中,即使將循環泵24的轉速在從2000rpm到3400rpm之間變化,平均值只要在2300rpm以上即可。再者,一旦使循環泵24的轉速變化時,即可使從灑水器所噴出的洗滌水的散佈範圍變化。因此,洗滌水可均勻地散佈於衣類。 The rotational speed of the circulation pump 24 may not be frequent in each step The range of the circulating pump rotation speed of 2300 rpm or more and 3800 rpm or less is assumed to mean that the average value of the number of revolutions of the circulation pump 24 in each step is included in this range. For example, in the pre-washing stirring step of step S7 (refer to Fig. 10), even if the number of revolutions of the circulation pump 24 is changed from 2000 rpm to 3400 rpm, the average value may be 2300 rpm or more. Further, when the number of revolutions of the circulation pump 24 is changed, the range of the washing water sprayed from the sprinkler can be changed. Therefore, the wash water can be uniformly dispersed in the clothes.
如以上說明,根據本實施形態相關之滾筒式洗衣乾燥機100的運轉步驟,較習知的20L/min左右的循環流量可大幅提高至35L/min以上60L/min以下,從縫隙狀的噴嘴朝滾筒內廣範圍進行洗滌水的灑水。循環流量大時提高洗淨比是在以充分的洗滌水浸透滾筒3的旋轉捲起衣類整體的狀態,使衣類落下,將包含於衣類的髒污以洗滌水落下的衝擊從衣類推出(敲打洗滌)。 As described above, according to the operation procedure of the drum-type washer-dryer 100 according to the present embodiment, the circulating flow rate of about 20 L/min can be greatly increased to 35 L/min or more and 60 L/min or less, from the slit-like nozzle toward A wide range of watering of the washing water is carried out in the drum. When the circulation flow rate is large, the cleaning ratio is increased in the state in which the entire washing machine is immersed in the rotation of the drum 3 with sufficient washing water, and the clothes are dropped, and the impact contained in the clothes is dropped from the clothes by the impact of the washing water (knock washing) ).
又,如第11圖表示,循環流量大於60L/min時洗淨比的上升大致飽和是在包含著衣類的水的量受到限制,即使增加所需以上流量,洗滌水會流到衣類的外側而無助於洗淨。並且,由於衣類整體為洗滌水所浸透,在清洗時可有效進行洗劑成分的稀釋,可同時提升清洗性能。 Further, as shown in Fig. 11, when the circulation flow rate is more than 60 L/min, the increase in the washing ratio is substantially saturated, and the amount of water containing the clothes is limited. Even if the required flow rate is increased, the washing water flows to the outside of the clothes. Helpless to wash. Further, since the entire garment is impregnated with the washing water, the dilution of the lotion component can be effectively performed during the washing, and the washing performance can be improved at the same time.
一般,直立式洗衣機由於槽的開口部是位 在上面側以高水位儲水清洗來進行洗滌,因此較少會發硬。但是,由於滾筒式洗衣乾燥機是開口部位在前面側一邊防止漏水一邊維持高水位非常困難。因此,本實施形態是大幅地增加循環流量,使充分的水包含著衣類,即使縮短敲打洗滌的時間仍可確保洗淨力,其結果,可降低衣類的發硬。亦即,不會使滾筒式洗衣乾燥機之特徵的節水性惡化,可以高洗淨力實現發硬少的洗滌。 Generally, the vertical washing machine is in place due to the opening of the groove. Washing is performed on the upper side with high water storage, so it is less likely to be hard. However, it is very difficult to maintain a high water level while preventing the water from leaking on the front side of the drum type laundry dryer. Therefore, in the present embodiment, the circulation flow rate is greatly increased, and sufficient water is contained in the clothing, and the cleaning power can be ensured even when the time of the tapping washing is shortened, and as a result, the hardening of the clothes can be reduced. In other words, the water-saving property of the characteristic of the drum type laundry dryer is not deteriorated, and the washing with less hardness can be realized with high washing power.
並且,變黑是主要從衣類除去的髒污的一部份由於再次附著於衣類(在污染現象)所產生。滾筒式洗衣乾燥機與直立式洗衣機比較具有使用水量少的特徵。但是,衣類的髒汙量與洗淨力一起時,洗滌水的髒污濃度會變得比滾筒式洗衣乾燥機的濃度高,因此容易變黑。一般,滾筒式洗衣乾燥機與直立式洗衣機比較使用水量為大約一半,髒污濃度成為大約兩倍。又,洗滌時間越長越容易變黑。 Also, blackening is a part of the dirt mainly removed from the clothing due to reattachment to clothing (in the case of contamination). The drum type laundry dryer has a feature of using less water than a vertical type washing machine. However, when the amount of dirt of the clothes is together with the detergency, the concentration of the washing water becomes higher than the concentration of the drum type washing and drying machine, so that it tends to be black. In general, the drum type laundry dryer uses about half the amount of water compared to the vertical type washing machine, and the dirt concentration is about twice. Moreover, the longer the washing time, the more likely it becomes black.
根據本發人等的檢討,滾筒式洗衣乾燥機與直立式洗衣機的洗滌時間大致相同的場合,滾筒式洗衣乾燥機在水量的差(洗滌水的髒污濃度的差)以上多會變黑。這是由於根據洗滌方法的不同為主要原因所造成。相對於直立式洗衣機將一類沉浸在洗滌水中的狀態進行洗滌,滾筒式洗衣乾燥機的洗滌則是重複進行以滾筒的旋轉將水中的衣類從水中捲起至空 中,並落下至水面。從衣類所除去的疏水性的髒污容易集中於水面。而該髒汙在衣類出入於水面時會再附著於衣類,而持續變黑。 According to the review by the present inventors, when the washing time of the drum type washing and drying machine is substantially the same as that of the vertical type washing machine, the drum type washing and drying machine tends to be black more than the difference in the amount of water (the difference in the concentration of the washing water). This is due to the difference in the washing method. Compared with the vertical washing machine, one type of washing is immersed in the washing water, and the washing of the drum type washing and drying machine is repeated to rotate the clothes in the water from the water to the empty with the rotation of the drum. Medium and fall to the surface. Hydrophobic dirt removed from clothing tends to concentrate on the water surface. The dirt will adhere to the clothing when it enters the water surface, and it will continue to darken.
本實施形態的滾筒式洗衣乾燥機100由於洗滌水的循環流量大,大量的洗滌水會灑向捲出至空中的衣類。因此,衣類會以如被洗滌水的膜所包覆的狀態落下至水中,使得水面的髒汙不易再附著,而具有抑制變黑的效果。此外,如上述,也具有提高洗淨力的效果,由於縮短了洗滌步驟的時間,可進一步抑制變黑。 In the drum type washing and drying machine 100 of the present embodiment, since the circulating flow rate of the washing water is large, a large amount of washing water is sprinkled on the clothes that are taken out to the air. Therefore, the clothes are dropped into the water in a state covered with a film of the washed water, so that the dirt on the water surface is less likely to reattach, and the effect of suppressing blackening is suppressed. Further, as described above, it also has an effect of improving the detergency, and since the time of the washing step is shortened, blackening can be further suppressed.
第12圖是表示循環泵的循環流量與衣類的明亮度變化(變黑)的關係之實驗結果的一例。實驗是同時重複進行附著人工皮脂髒汙或碳等無機質髒汙的衣類與白色衣類的洗滌(布量3kg)。第12圖為洗滌5循環後的數據。明亮變化是從白色衣類洗滌後的明亮度減去新品明亮度的值,值越大即變黑越大。由第12圖可得知,循環流量越多明亮度變化越少,越不易變黑。不僅洗徑力同時考慮變黑時,循環流量是以增加至68L/min左右(循環泵轉速4200rpm)為佳,本實驗條件幾乎可抑制變黑的產生。亦即,一旦考慮上述循環流量的較理想下限值時,本實施形態的循環泵24的水的循環流量是以35L/min以上、68L/min以下為佳。 Fig. 12 is an example of experimental results showing the relationship between the circulation flow rate of the circulation pump and the change in brightness (blackening) of the clothes. In the experiment, washing (coating amount: 3 kg) of clothing and white clothes to which artificial sebum stains or inorganic stains such as carbon were adhered was repeated. Figure 12 shows the data after 5 cycles of washing. The bright change is the value obtained by subtracting the brightness of the new product from the brightness after washing the white clothes. The larger the value, the greater the blackening. As can be seen from Fig. 12, the more the circulating flow rate, the less the brightness changes, and the more difficult it is to turn black. Not only when the cleaning force is considered, but also when the blackening is considered, the circulation flow rate is preferably increased to about 68 L/min (circulation pump rotation speed of 4,200 rpm), and the experimental conditions can almost suppress the occurrence of blackening. In other words, when the desired lower limit value of the circulation flow rate is considered, the circulation flow rate of the water of the circulation pump 24 of the present embodiment is preferably 35 L/min or more and 68 L/min or less.
並且,本實施形態的循環泵馬達47是如上述為確保此循環流量,形成可以2300~4200rpm的轉速旋轉。其結果,會有在循環泵馬達47產生軸電流之虞,但循環泵馬達47中,如上述可藉著電絕緣機構60防止軸電流的產生。 Further, the circulation pump motor 47 of the present embodiment is rotated at a number of revolutions of 2,300 to 4,200 rpm as described above in order to secure the circulating flow rate. As a result, there is a possibility that the circulation pump motor 47 generates a shaft current. However, in the circulation pump motor 47, the shaft current can be prevented from being generated by the electrical insulation mechanism 60 as described above.
因此,滾筒式洗衣乾燥機100可防止循環泵馬達47之軸承49的電蝕。 Therefore, the drum type laundry dryer 100 can prevent the electric corrosion of the bearing 49 of the circulation pump motor 47.
以上,雖針對本實施形態已作說明,但本發明不限於上述實施形態,可實施種種的形態。 Although the present embodiment has been described above, the present invention is not limited to the above embodiment, and various embodiments can be implemented.
上述實施形態中,雖針對滾筒式洗衣乾燥機100已作說明,但不具乾燥功能滾筒式洗衣機也可運用本發明。 In the above embodiment, the drum type washing and drying machine 100 has been described, but the present invention can also be applied to a drum type washing machine which does not have a drying function.
