洗濯機では、昨今節水が求められているが、水量を減らし過ぎると、洗濯物に十分な洗濯水が行き渡らずに、洗浄力やすすぎが悪化する。そこで、外槽内に溜まった洗濯水を、洗濯兼脱水槽である内槽の上方から内槽内に降り掛けるように循環させる洗濯水循環機構を備えた洗濯機が提案されている。この洗濯水循環機構としては、内槽や回転翼の回転による遠心力で外槽内の底に溜まった洗濯水を巻き上げる方式の他、循環ポンプを用いて外槽内の底に溜まった洗濯水を巻き上げる方式もある。例えば、下記特許文献１には、循環ポンプでくみ上げた洗濯水を内槽上方に設けた散水ノズルから散布する洗濯機が記載されている。また、下記特許文献１には、洗濯水を循環させる散水ノズルだけでなく、水道水を直接内槽内に散水するために設けた複数個の散水口も開示されている。 In washing machines, water saving is required recently. However, if the amount of water is reduced too much, sufficient washing water does not reach the laundry, and the cleaning power and excessiveness deteriorate. In view of this, there has been proposed a washing machine including a washing water circulation mechanism that circulates the washing water accumulated in the outer tub so as to be dropped into the inner tub from above the inner tub as a washing and dewatering tub. This washing water circulation mechanism includes a method of winding up washing water collected at the bottom of the outer tub by centrifugal force due to rotation of the inner tub and rotor blades, and washing water collected at the bottom of the outer tub using a circulation pump. There is also a winding method. For example, Patent Document 1 below describes a washing machine that sprays washing water pumped up by a circulation pump from a watering nozzle provided above an inner tub. Patent Document 1 below discloses not only a watering nozzle for circulating washing water but also a plurality of watering ports provided for watering tap water directly into the inner tank.
上記特許文献１に記載の洗濯機では、各散水口から出る水が細切れに分散し易く、水道水の散水にムラが生じていた。その結果、洗いムラまたはすすぎムラを生じさせる可能性があった。 In the washing machine described in the above-mentioned Patent Document 1, the water coming out of each water spout is easily dispersed into small pieces, and the water sprinkling is uneven. As a result, there was a possibility of causing uneven washing or rinsing unevenness.
本発明の目的は、このような課題を鑑みて成されたものであり、その目的は、洗いムラやすすぎムラを低減し、洗浄性能の向上または洗濯時間の短縮を可能とした洗濯機を提供することにある。 The object of the present invention is made in view of such problems, and the object thereof is to provide a washing machine capable of reducing washing unevenness and excessive unevenness and improving washing performance or shortening washing time. There is to do.

Reference numeral 1 denotes a rectangular cylindrical outer frame constituting the outer shell. Reference numeral 2 denotes a top cover attached to the upper part of the outer frame 1. Reference numeral 3 denotes an outer lid 3 attached to the top cover 2. The outer lid 3 is bent at the center and opened, and an operation panel 8 provided with various operation button switches 6 and 6a and indicators 7 and 25 is provided on the front side thereof. The operation panel 8 is electrically connected to a control device 14 provided at the bottom of the machine body. Reference numeral 5 denotes a power switch provided on the front surface of the top cover 2. Parts related to water supply and drying such as the water supply unit 4, the heater 20, and the blower fan 19 are built in the rear part (back side) of the top cover 2, and a detergent / finishing agent container 28 is built in the front side of the top cover 2. .
９は、洗濯兼脱水槽で、その外周壁に通水および通風のための複数の小さな貫通穴９ａを有し、その底壁に通水および通風のための複数の貫通穴９ｂを有し、その上縁部に流体バランサー９ｃを備え、底部の内側には回転自在に回転翼１１を回転可能に設置する。 9 is a washing and dewatering tub having a plurality of small through holes 9a for water flow and ventilation on its outer peripheral wall, and a plurality of through holes 9b for water flow and ventilation on its bottom wall, A fluid balancer 9c is provided at the upper edge, and a rotary blade 11 is rotatably installed inside the bottom.
前記回転翼１１は、図３に示すように、その上面に、回転することによって該洗濯兼脱水槽９内に投入されて回転翼１１上に乗っている洗濯物に上向きの動きを繰り返し発生するように、回転方向になだらかに傾斜した複数の傾斜面を形成する***部１１ａと、多数の水抜き貫通穴１１ｂを備える。***部１１ａは、回転方向に山型に傾斜し、且つ外周部位が順次に高くなるように径方向に傾斜し、更に、外周端面１１ｃは上部を中心側に倒すように傾斜させた傾斜面とする。本実施例では、***部１１ａを２個設けてある。 As shown in FIG. 3, the rotating blades 11 repeatedly generate upward movement in the laundry that is put into the washing and dewatering tub 9 and put on the rotating blades 11 by rotating on the upper surface thereof. Thus, it has the protruding part 11a which forms the some inclined surface which inclined gently in the rotation direction, and many drainage through-holes 11b. The raised portion 11a is inclined in a mountain shape in the rotation direction, and is inclined in the radial direction so that the outer peripheral portions are sequentially increased, and the outer peripheral end surface 11c is an inclined surface inclined so as to tilt the upper portion toward the center side. To do. In this embodiment, two raised portions 11a are provided.
回転翼１１が回転すると、この回転翼１１上の洗濯物は、回転翼１１上を滑りながら該回転翼１１の回転方向に回転すると共に***部１１ａに押されて上下方向に振動する。この時、洗濯水を循環しながら洗濯物の上方から降り掛け、洗濯物へ洗濯水を行き渡らせる。こうすることで、洗濯兼脱水槽９内に洗濯水を溜めなくても、洗濯物を洗濯することができ、大幅な節水が可能である。したがって、洗濯物へ洗濯水を均一散布ができないと十分な洗浄力を実現できない。 When the rotating blade 11 rotates, the laundry on the rotating blade 11 rotates in the rotating direction of the rotating blade 11 while sliding on the rotating blade 11, and is pushed by the raised portion 11a and vibrates in the vertical direction. At this time, the washing water is circulated from above the laundry while circulating the washing water, and the washing water is spread over the laundry. By doing so, the laundry can be washed without storing the washing water in the washing and dewatering tub 9, and significant water saving is possible. Therefore, sufficient washing power cannot be realized unless the washing water can be uniformly sprayed on the laundry.
１０は、前記洗濯兼脱水槽９を内包する外槽であり、その底部の外側には洗濯脱水駆動装置を取り付ける。この外槽１０は、図示説明は省略するが、外枠１の上端部の四隅部に設けた隅板に係止して垂下させた４本の支持棒に緩衝装置を介して該外槽１０の四方位を係合させて均等に支持することにより該外枠１の中心部に懸垂する。前記洗濯脱水駆動装置は、インバータ駆動電動機または可逆回転型のコンデンサ分相単相誘導電動機を使用した洗濯脱水駆動電動機１３と電磁操作クラッチ機構１２と遊星歯車減速機構を内蔵し、洗濯脱水駆動電動機１３と電磁操作クラッチ機構１２を制御することによって、洗濯兼脱水槽９を静止させるように係止または自由に回転できるように解放した状態で回転翼１１を繰り返し正逆回転させる洗濯駆動モードと、洗濯兼脱水槽９と回転翼１１を一体的に同一方向に回転させる脱水駆動モードを選択的に実行する駆動機能を有する。 Reference numeral 10 denotes an outer tub containing the washing / dehydrating tub 9, and a washing / dehydrating drive device is attached to the outside of the bottom of the tub. Although not shown in the drawings, the outer tub 10 has four support rods that are suspended from the corner plates provided at the four corners of the upper end of the outer frame 1 and are suspended from the outer tub 10 via a shock absorber. These four directions are engaged and supported uniformly so as to be suspended from the central portion of the outer frame 1. The washing / dehydrating drive device incorporates a washing / dehydrating drive motor 13 using an inverter-driven motor or a reversible rotation type capacitor phase-separated single-phase induction motor, an electromagnetic operation clutch mechanism 12, and a planetary gear reduction mechanism. And the electromagnetic operation clutch mechanism 12 to control the washing / dehydrating tub 9 so as to be stationary or freely rotated so that the rotary blades 11 are repeatedly rotated forward and reverse in a state of being released. It has a drive function for selectively executing a dehydration drive mode in which the cum dewatering tank 9 and the rotor blade 11 are integrally rotated in the same direction.
２７は振動センサで、外槽１０の側面外側に設置してあり、洗濯兼脱水槽９が高速回転する脱水時の振動を検出する。 A vibration sensor 27 is installed outside the side surface of the outer tub 10 and detects vibration during dehydration in which the washing and dewatering tub 9 rotates at high speed.
１０ａは外槽１０の上面に設けた槽カバーである。図４は、槽カバー１０ａを上方から見た平面図である。槽カバー１０ａの前側から約２／３の部分には洗濯物投入口１０ａ１を有し、後面１０ａ２には槽カバー１０ａの上面と下面を連通する温風吹き出し口２２ａ，給水入口３２，循環水入口３３が設けてある。また、槽カバー１０ａの前方には、洗剤・柔軟仕上剤入口２８ａが設けてある。２３は、洗濯物投入口１０ａ１を覆うように設けた内蓋である。内蓋２３は、ヒンジ２３ｂで開閉自在に取り付けられており、取っ手２３ａを上方に持ち上げることで、内蓋２３のロック（図示せず）が解除され、取っ手２３ａを下方に押すことでロックされるようになっている。 A tank cover 10 a is provided on the upper surface of the outer tank 10. FIG. 4 is a plan view of the tank cover 10a as viewed from above. About 2/3 from the front side of the tank cover 10a has a laundry input port 10a1, and the rear surface 10a2 has a hot air outlet 22a communicating with the upper and lower surfaces of the tank cover 10a, a water supply inlet 32, and a circulating water inlet. 33 is provided. Further, a detergent / softening agent inlet 28a is provided in front of the tank cover 10a. Reference numeral 23 denotes an inner lid provided so as to cover the laundry input port 10a1. The inner lid 23 is openably / closably attached by a hinge 23b, and the lock (not shown) of the inner lid 23 is released by lifting the handle 23a upward, and is locked by pushing the handle 23a downward. It is like that.
３０は槽カバー１０ａ後ろ側の下面（洗濯兼脱水槽９側）に設けた循環水カバーである。図５は、循環水カバー３０および給水カバー３６を取り付けた槽カバー１０ａの後ろ側を下方から見た平面図である。 Reference numeral 30 denotes a circulating water cover provided on the lower surface (the washing / dehydrating tub 9 side) on the rear side of the tub cover 10a. FIG. 5 is a plan view of the rear side of the tank cover 10a to which the circulating water cover 30 and the water supply cover 36 are attached as viewed from below.
循環水カバー３０は、循環水入口３３から流入した洗濯水を槽カバー１０ａの洗濯物投入口１０ａ１側に導き、洗濯兼脱水槽９内に散水するために設けたものである。給水カバー３６は、給水入口３２から流入した水道水を洗濯物投入口１０ａ１側に導き、洗濯兼脱水槽９内に散水するために設けたものである。給水カバー３６には、洗濯兼脱水槽９内に向かって開口した複数個の散水口３５が設けてある。 The circulating water cover 30 is provided to guide the washing water flowing in from the circulating water inlet 33 to the laundry input port 10a1 side of the tank cover 10a and sprinkle it into the washing and dehydrating tank 9. The water supply cover 36 is provided to guide the tap water flowing in from the water supply inlet 32 to the laundry input port 10a1 side and sprinkle it into the washing and dewatering tub 9. The water supply cover 36 is provided with a plurality of water spouts 35 opened toward the inside of the washing and dewatering tub 9.
次に、散水口３５から散布される水道水のシャワーについて、詳細に説明する。図６は、給水カバー３６を上方から見た平面図であり、図７は、この給水カバー３６を手前側（洗濯物投入口１０ａ１側）から見たときの断面図であり、図８は、給水カバー３６を斜め下方から見た斜視図である。槽カバー１０ａに形成された給水入口３２から流入する水道水は、まず、給水カバー３６の水受部３６Ａで受け止められる。給水カバー３６内へ流入した水道水は、洗濯物投入口１０ａ１側、望ましくは洗濯兼脱水槽９のほぼ中心軸側へ向かって、上流給水流路３６Ｂを流れる。ここで、給水カバー３６の底面に設けられる給水流路は、側壁４７と仕切壁４６により略Ｕ字状に区画されており、仕切壁４６よりも上流側に上流給水流路３６Ｂが、仕切壁４６よりも下流側に下流給水流路３６Ｃが位置している。上流給水流路３６Ｂを流れる水道水は、下流側の下流給水流路３６Ｃへ至る間に、仕切壁４６の先端部で方向転換され、下流給水流路３６Ｃへ導かれる。なお、仕切壁４６は板状で内部に空間が存在しないものに限らず、複数部材で形成するなどして内部に空間が存在するものであっても良い。 Next, a shower of tap water sprayed from the water spout 35 will be described in detail. FIG. 6 is a plan view of the water supply cover 36 as viewed from above, and FIG. 7 is a cross-sectional view of the water supply cover 36 when viewed from the front side (laundry input port 10a1 side). It is the perspective view which looked at the water supply cover 36 from diagonally downward. The tap water flowing from the water supply inlet 32 formed in the tank cover 10 a is first received by the water receiving portion 36 </ b> A of the water supply cover 36. The tap water that has flowed into the water supply cover 36 flows through the upstream water supply passage 36 </ b> B toward the laundry input port 10 a 1, preferably toward the substantially central axis of the washing and dewatering tub 9. Here, the water supply flow path provided on the bottom surface of the water supply cover 36 is partitioned in a substantially U shape by the side wall 47 and the partition wall 46, and the upstream water supply flow path 36 </ b> B is disposed upstream of the partition wall 46. A downstream water supply flow path 36 </ b> C is located on the downstream side of 46. The tap water flowing through the upstream water supply channel 36B is redirected at the tip of the partition wall 46 to the downstream water supply channel 36C and guided to the downstream water supply channel 36C. The partition wall 46 is not limited to a plate-like shape having a space inside, and may be formed by a plurality of members and have a space inside.
本実施例の給水流路は水平方向に延びる構造となっているが、厳密に水平なものに限らず、上流給水流路３６Ｂの上流側から下流給水流路３６Ｃの下流側にかけて徐々に底面が低くなるように形成しても良い。一方で、図７に示すように、上流給水流路３６Ｂについては周壁４７側より仕切壁４６側の方が底面を低く形成し、下流給水流路３６Ｃについては仕切壁４６より周壁４７側の方が底面を低く形成している。そして、給水カバー３６の底面に形成される給水流路の下流側で最も低い部分に、水抜穴４５を設ける。これにより、給水カバー３６内に水が残留し難くなり、カビ等の発生も抑制できる。なお、従来の給水カバー４８は、図９に示すように散水口４９を底面に設ける構造であるため残水の可能性は低いが、本実施例のように周壁４７に散水口３５を設ける構造の場合は、上述のような構成は有効である。 The water supply channel of the present embodiment has a structure extending in the horizontal direction, but is not limited to a strictly horizontal one, and the bottom surface gradually extends from the upstream side of the upstream water supply channel 36B to the downstream side of the downstream water supply channel 36C. You may form so that it may become low. On the other hand, as shown in FIG. 7, for the upstream water supply channel 36B, the partition wall 46 side forms a lower bottom than the peripheral wall 47 side, and for the downstream water supply channel 36C, the peripheral wall 47 side is closer to the partition wall 46. Has a lower bottom. And the drain hole 45 is provided in the lowest part in the downstream of the water supply flow path formed in the bottom face of the water supply cover 36. Thereby, it becomes difficult for water to remain in the water supply cover 36, and generation | occurrence | production of mold | fungi etc. can also be suppressed. The conventional water supply cover 48 has a structure in which the water spout 49 is provided on the bottom surface as shown in FIG. 9, so the possibility of remaining water is low, but a structure in which the water spout 35 is provided in the peripheral wall 47 as in this embodiment. In this case, the configuration as described above is effective.
また、給水カバー３６の周壁４７に設けられる散水口３５は、給水流路の上流側から下流側へ向かう方向に長く、この方向に垂直な方向に短く形成されている。このため、散水口３５から散布されるシャワーが水平方向へ広がり易くなり、従来届かなかった場所へも散布でき、かつ、散布ムラも少なくなる。 Further, the water spout 35 provided in the peripheral wall 47 of the water supply cover 36 is long in the direction from the upstream side to the downstream side of the water supply channel, and is short in the direction perpendicular to this direction. For this reason, the shower sprayed from the water sprinkling port 35 is easy to spread in the horizontal direction, can be sprayed to a place that has not reached before, and scattering unevenness is reduced.
本実施例における給水カバー３６により、洗濯兼脱水槽９内へ水道水を降りかけるときの作用効果について、図６を用いて更に詳細に説明する。まず、上流給水流路３６Ｂ内の水道水は、仕切壁４６に沿って流れる主流と、周壁４７に沿って流れる副流に大別される。主流は、仕切壁４６の先端と対向する位置にある散水口３５ａから多くの水が吐出される。このとき、副流が、周壁４７の曲面部分を通りながら、水道水が流れる方向に沿うスリット状に形成された散水口３５ａに至ることで、副流の遠心力によって主流が下流側へ引っ張られる。その結果、主流と副流とで形成されるシャワーが、水平方向への広がりを以って帯状に散布され、洗濯兼脱水槽９内の洗濯物へ満遍なく水道水が当たるようになるため、すすぎ性能が大きく向上する。 The operation and effect when the tap water is poured into the washing and dewatering tub 9 by the water supply cover 36 in this embodiment will be described in more detail with reference to FIG. First, tap water in the upstream water supply flow path 36 </ b> B is roughly divided into a main flow that flows along the partition wall 46 and a substream that flows along the peripheral wall 47. In the mainstream, a large amount of water is discharged from the water spout 35 a located at the position facing the tip of the partition wall 46. At this time, the main stream is pulled downstream by the centrifugal force of the substream by the substream reaching the water spout 35a formed in a slit shape along the flowing direction of the tap water while passing through the curved surface portion of the peripheral wall 47. . As a result, the shower formed by the main stream and the side stream is spread in a strip shape with a spread in the horizontal direction, so that the tap water is uniformly applied to the laundry in the washing and dehydrating tub 9. Performance is greatly improved.
更に本実施例では、仕切壁４６の先端と、この先端と対向する位置にある散水口３５ａとの間の流路（図６のＸ）面積は、散水口３５のない上流側における仕切壁４６と周壁４７とで囲まれる流路（図６のＹ）面積よりも小さくしている。このため、水道水の水圧が低い場合であっても、散水口３５ａ付近で実質的に水圧を高めることができ、シャワーの勢いを強くすることが可能となる。散水口３５自体を小さくすることで圧力を高める方法もあるが、この方法だとゴミが詰まり易く、水も吐出され難くなる可能性があるため、上述のように給水流路を狭めた場所から散水する構造が望ましい。 Furthermore, in this embodiment, the area of the flow path (X in FIG. 6) between the tip of the partition wall 46 and the water spray port 35a located at the position facing the tip is the partition wall 46 on the upstream side without the water spray port 35. And the area surrounded by the peripheral wall 47 (Y in FIG. 6). For this reason, even when the water pressure of tap water is low, the water pressure can be substantially increased in the vicinity of the water spout 35a, and the momentum of the shower can be increased. There is also a method of increasing the pressure by reducing the water sprinkling port 35 itself, but this method tends to clog dust and it may be difficult to discharge water, so from the place where the water supply flow path is narrowed as described above A structure that sprinkles water is desirable.
また、仮に周壁４７のうち曲面部分よりも上流側に散水口３５を設けると、一部の副流だけが吐出されることになるため、シャワーが全体として弱くなってしまう。このため、最上流側の散水口３５ａの一部だけが、仕切壁４６を超えて上流側に張り出すような構造とするのが望ましい。 Further, if the sprinkling port 35 is provided on the upstream side of the curved surface portion of the peripheral wall 47, only a partial side flow is discharged, so that the shower becomes weak as a whole. For this reason, it is desirable to have a structure in which only a part of the uppermost stream sprinkling port 35a protrudes beyond the partition wall 46 to the upstream side.
本実施例における散水口３５は複数設けられており、隣り合う散水口３５がリブ３９で区分けされている。特に、最上流側の散水口３５ａと、その１つ下流側にある散水口３５ｂとの間に位置するリブ３９は、下流側へ傾斜するように形成されている。仮に、リブを放射状（周壁４７の曲面に対して垂直方向）に形成した場合、その両側の散水口から吐出される水に隙間が生じ、両側の散水口からの水が分離したまま散布され易い。しかし、上述のようにリブ３９に傾斜を設けることで、両側の散水口３５から隙間なくシャワーを散布することが可能となる。 In this embodiment, a plurality of water spouts 35 are provided, and adjacent water spouts 35 are separated by ribs 39. In particular, the rib 39 located between the water spray port 35a on the most upstream side and the water spray port 35b on one downstream side thereof is formed so as to be inclined toward the downstream side. If the ribs are formed in a radial pattern (perpendicular to the curved surface of the peripheral wall 47), there is a gap in the water discharged from the sprinkling ports on both sides, and the water from the sprinkling ports on both sides is easily sprayed while being separated. . However, by providing the rib 39 with an inclination as described above, the shower can be sprayed from the sprinkling ports 35 on both sides without any gap.
本実施例のリブ３９は、周壁４７に散水口３５を形成することで必然的に低下する剛性を、補強する役割も果たしているが、別の手段で給水カバー３６の強度を維持できれば、リブ３９を設けずに細長い散水口３５を一つだけ設ける構成であっても良い。リブ３９がない場合は、散水口３５から吐出される水が分離し難いため、シャワーが連続的な帯状になり易い利点もある。 The rib 39 of this embodiment also serves to reinforce the rigidity that is inevitably reduced by forming the water spout 35 in the peripheral wall 47, but if the strength of the water supply cover 36 can be maintained by another means, the rib 39 The structure which provides only one elongate sprinkling port 35 without providing may be sufficient. When the rib 39 is not provided, the water discharged from the water spout 35 is difficult to separate, and there is an advantage that the shower is likely to be a continuous band.
散水口３５の数は３個に限定されるものではないが、散水口３５を多くし過ぎるとリブ３９も多くなってしまい、水の抵抗が増加して、シャワーの勢いが弱くなる可能性がある。また、散水口３５を最下流側まで設けてしまうと、流体バランサー９ｃにまで届いてしまい、水跳ねの可能性も生じるため、最下流側に設ける散水口３５ｃは、少なくとも水抜穴４５よりも上流側に位置させる構造が望ましい。 The number of water spouts 35 is not limited to three, but if the number of water spouts 35 is increased too much, the number of ribs 39 also increases, water resistance increases, and the shower momentum may be weakened. is there. Further, if the sprinkling port 35 is provided to the most downstream side, it reaches the fluid balancer 9c, and there is a possibility of water splashing. Therefore, the sprinkling port 35c provided on the most downstream side is at least upstream of the drain hole 45. A structure located on the side is desirable.
また、本実施例の各散水口３５は、その上端高さはいずれも同程度であるが、その下端高さは下流側の散水口３５の方が上に位置している。さらに、同じ散水口３５でも下流側の下端の方が上流側の下端よりも上になるように形成されている。このため、図１１に示す通り、下流側の散水口３５ｃから吐出される水を、洗濯兼脱水槽９の内壁面のうち高い位置に当てることができる。その結果、洗濯物の容量が多い場合でも、上の方にある洗濯物に対して散水することが可能となり、すすぎムラが低下する。 In addition, each of the water spouts 35 of the present embodiment has the same upper end height, but the lower end height of the water spout 35 is located on the upper side. Furthermore, the same sprinkling port 35 is formed so that the lower end on the downstream side is higher than the lower end on the upstream side. For this reason, as shown in FIG. 11, the water discharged from the downstream sprinkling port 35 c can be applied to a higher position on the inner wall surface of the washing and dewatering tub 9. As a result, even when the capacity of the laundry is large, it becomes possible to spray water on the upper laundry, and the rinsing unevenness is reduced.
次に、本実施例によるシャワーの散布態様を、従来と比較して説明する。従来の給水カバー４８では、図９のように放射状の散水口４９を形成しており、ほとんどの散水口４９から吐出される水は、途切れ途切れにそのまま落下する態様となる。このため、図１２に示す通り、シャワーとシャワーの間で水が当たらない箇所が多く生じるだけでなく、洗濯兼脱水槽９の内壁面付近の上の方にある洗濯物にはシャワーが届き難い。 Next, the spraying mode of the shower according to the present embodiment will be described in comparison with the conventional case. In the conventional water supply cover 48, a radial sprinkling port 49 is formed as shown in FIG. 9, and the water discharged from most of the sprinkling ports 49 falls as it is without interruption. For this reason, as shown in FIG. 12, not only a lot of places where water does not hit between the showers are generated, but the shower is difficult to reach to the laundry near the inner wall surface of the washing / dehydrating tub 9. .
これに対して、本実施例のような周方向に形成した散水口３５によれば、図１１に示すように、シャワーが帯状に満遍なく広がるだけでなく、上の方にある洗濯物にもシャワーが届き易くなる。図１０は、本実施例による回転シャワーを上から見たときの様子を示す図であり、矢印の太さは流量と流速の大きさを示している。散水口３５ａから吐出された水Ｓａは流量と流速が大きく勢いは強いため、高いすすぎ性能が得られる。一方で、散水口３５ｂ，３５ｃから吐出された水Ｓｂ，Ｓｃについても流量と流速が小さく勢いは弱いものの、洗濯兼脱水槽９の後部の高い場所へも散水が可能となり、すすぎムラが抑制できる。なお、図１０では、各散水口３５から吐出される水を便宜上Ｓａ〜Ｓｃの矢印で示したが、実際にはこれらは分離しておらず、一様な帯状となっている。 On the other hand, according to the water spout 35 formed in the circumferential direction as in the present embodiment, as shown in FIG. 11, the shower not only spreads out in a band shape, but also in the upper laundry. Is easier to reach. FIG. 10 is a diagram showing a state when the rotary shower according to the present embodiment is viewed from above, and the thickness of the arrows indicates the flow rate and the flow velocity. Since the water Sa discharged from the water spout 35a has a large flow rate and flow velocity and a strong momentum, high rinsing performance can be obtained. On the other hand, the water Sb and Sc discharged from the water sprinkling ports 35b and 35c also have a small flow rate and flow velocity, and the momentum is weak. . In addition, in FIG. 10, although the water discharged from each water sprinkling port 35 was shown with the arrow of Sa-Sc for convenience, these are not isolate | separated in fact but become a uniform strip | belt shape.
上述の説明はすすぎのときの作用効果が中心であったが、洗いのときに同様のシャワーを散布すれば、当然ながら洗いムラの低減にも寄与する。 Although the above description has focused on the action and effect at the time of rinsing, if a similar shower is sprayed at the time of washing, it naturally contributes to the reduction of washing unevenness.
次に、循環水を用いたシャワーについて説明する。循環水カバー３０には循環水路３７が形成されている。循環水路３７は一端が循環水入口３３とつながっており、他端はノズル３４に接続している。ノズル３４は、槽カバー１０ａの左右方向の略中央で、槽カバー１０ａの後面１０ｂの前縁付近にあり、洗濯兼脱水槽９の中心から後ろ側に位置している。循環水路３７の途中には糸屑フィルタ３８が着脱可能に設けてあり、内蓋２３を開き取っ手２３ａを洗濯物投入口１０ａ１側に引くことで取り外すことができる。 Next, a shower using circulating water will be described. A circulating water channel 37 is formed in the circulating water cover 30. The circulating water channel 37 has one end connected to the circulating water inlet 33 and the other end connected to the nozzle 34. The nozzle 34 is located approximately at the center in the left-right direction of the tank cover 10 a, near the front edge of the rear surface 10 b of the tank cover 10 a, and is located on the rear side from the center of the washing / dehydrating tank 9.

Supply in. The cooling water electromagnetic valve 4d, which is the fourth valve, is connected to the dehumidifying mechanism 2b in the drying duct 22 and supplies cooling water.
外槽１０の底面には、エアトラップ２１ａが設けてあり、内部の圧力がチューブ２１ｂを介して水位センサ２１に伝えられ、外槽９内の洗濯水の水位を検知する。 An air trap 21 a is provided on the bottom surface of the outer tub 10, and the internal pressure is transmitted to the water level sensor 21 via the tube 21 b to detect the water level of the washing water in the outer tub 9.

In the middle of the circulation pipe 17, there are a circulation pump 16 and a foreign matter trap 18 provided at the bottom of the machine body, and a drainage hose 24 is connected to the foreign matter trap 18 via a drainage valve 15. When the circulation pump 16 is operated, the washing water in the outer tub 10 is conveyed from the water vent 10 b provided at the bottom of the outer tub to the upper portion of the outer tub 10 through the circulation pipe 17, and from the circulation water inlet 33 to the circulating water cover. 30 enters the circulation channel 37, the yarn waste is removed by the yarn waste filter 38, and flows into the washing and dewatering tub 9 from the nozzle 34 (see the arrow in FIG. 5).
２２は、乾燥ダクトで、乾燥通水通気口１０ｂと温風吹き出し口２２ａとの間を接続する。乾燥ダクト２２の途中には、送風ファン１９，ヒータ２０，リントフィルタ（図示せず），除湿機構２２ｂ，温度センサ２６が設けてある。送風ファン１９を運転し、ヒータ２０に通電すると、洗濯兼脱水槽９内に温風が吹き込み、洗濯物を温め水分が蒸発する。
高温多湿となった空気は、貫通穴９ａ，９ｂを通り外槽１０に出て、通水通気口１０ｂから乾燥ダクト２２に吸い込まれ、除湿機構２ｂを流下する冷却水で冷却除湿されて乾いた低温空気となり、ヒータ２０で再度加熱され、洗濯兼脱水槽９内に吹き込むように循環する。
Reference numeral 22 denotes a drying duct, which connects the dry water vent 10b and the hot air outlet 22a. In the middle of the drying duct 22, a blower fan 19, a heater 20, a lint filter (not shown), a dehumidifying mechanism 22b, and a temperature sensor 26 are provided. When the blower fan 19 is operated and the heater 20 is energized, warm air blows into the washing and dewatering tub 9, warming the laundry and evaporating moisture.
The air that has become hot and humid passes through the through holes 9a and 9b, exits the outer tub 10, is sucked into the drying duct 22 through the water vent 10b, and is cooled and dehumidified with cooling water flowing down the dehumidifying mechanism 2b and dried. It becomes low-temperature air, is heated again by the heater 20, and circulates so as to blow into the washing and dewatering tub 9.

Control energization. Further, it is connected to a 7-segment light emitting diode display 25, a light emitting diode 7 and a buzzer 43 for informing the user of the operating state of the washing machine.
前記マイクロコンピュータ４０は、電源スイッチ５が押されて電源が投入されると起動し、図１５に示すような洗濯および乾燥の制御処理を実行する。 The microcomputer 40 is activated when the power switch 5 is pressed and the power is turned on, and executes a washing and drying control process as shown in FIG.
まず、布量センシング工程Ｓ１では、洗濯兼脱水槽９を回転させ、洗い水を給水する前の乾布状態において、洗濯兼脱水槽９を静止させた状態で回転翼１１を一方向に回転させたときに、回転翼１１に作用する回転負荷量に基づいて洗濯物の布量を検出するように洗濯脱水駆動装置における洗濯脱水駆動電動機１３と電磁操作クラッチ機構１２を制御し、検出した布量に基づいて洗剤の適量（洗剤量）を求めることによって行う。洗剤量は、予め設定した布量と洗剤量の対照テーブルを参照することによって求める。そして、求めた洗剤量を操作パネル８の表示器２５に表示する。使用者は、表示された量の粉末洗剤を洗剤・仕上剤容器２８の洗剤投入室に投入した後、外蓋３を閉じるように操作する。 First, in the cloth amount sensing step S1, the washing and dewatering tub 9 is rotated, and the rotary blade 11 is rotated in one direction with the washing and dewatering tub 9 being stationary in the dry cloth state before supplying the washing water. In some cases, the laundry dehydration drive motor 13 and the electromagnetic operation clutch mechanism 12 in the laundry dehydration drive device are controlled so as to detect the amount of laundry based on the rotational load acting on the rotary blades 11, and the detected fabric amount is obtained. Based on determining the appropriate amount of detergent (detergent amount). The detergent amount is determined by referring to a preset table of cloth amount and detergent amount. Then, the determined amount of detergent is displayed on the display 25 of the operation panel 8. The user operates to close the outer lid 3 after putting the indicated amount of the powder detergent into the detergent charging chamber of the detergent / finishing agent container 28.
次に、給水・洗剤投入工程Ｓ２では、洗剤給水電磁弁４ｂを開弁し、洗剤・仕上剤容器２８の洗剤投入室に水道水を供給する。洗剤投入室に注水された水道水は、投入された洗剤とともに、洗剤・仕上剤入口３８を通って、外槽１０の底部に落下する。また、洗剤給水電磁弁４ｂが開弁されてから所定時間経過後（または所定の洗剤溶かし水位まで到達した後）に洗剤給水電磁弁４ｂを閉弁する。 Next, in the water supply / detergent charging step S <b> 2, the detergent water supply electromagnetic valve 4 b is opened to supply tap water to the detergent charging chamber of the detergent / finishing agent container 28. The tap water poured into the detergent charging chamber falls together with the poured detergent to the bottom of the outer tub 10 through the detergent / finishing agent inlet 38. Further, the detergent water supply electromagnetic valve 4b is closed after a predetermined time has elapsed since the detergent water supply electromagnetic valve 4b was opened (or after reaching a predetermined detergent melted water level).
洗剤溶かし工程Ｓ３では、洗濯兼脱水槽９と回転翼１１を一体的に一方向に緩速回転（約毎分７０回転）させることによって、洗濯兼脱水槽９の底面で外槽１０の底部に投入された洗剤溶かし水と粉末洗剤とを攪拌して、高濃度の洗い水を生成する。 In the detergent dissolving step S3, the washing / dehydrating tub 9 and the rotary blade 11 are integrally rotated slowly in one direction (about 70 rotations per minute), so that the bottom of the washing / dehydrating tub 9 is placed on the bottom of the outer tub 10. The added detergent-dissolved water and powder detergent are stirred to produce high-concentration wash water.
前洗い工程Ｓ４では、洗濯兼脱水槽９を静止させた状態で回転翼１１を正逆回転させる攪拌を間欠的に行い、回転翼１１の正逆回転中に循環ポンプ１６を運転することによって外槽１０の底部の洗い水をノズル３４から降り掛ける。回転翼１１と循環ポンプ１６の停止期間中に水位センサ２１の検出信号を参照しながら槽内給水電磁弁４ａを開弁して補給水する。この運転を複数回繰り返すことにより、高濃度の洗い水を洗濯物に馴染ませる。 In the pre-washing step S4, stirring is performed by rotating the rotating blade 11 forward and backward intermittently while the washing and dewatering tub 9 is stationary, and the circulation pump 16 is operated while the rotating blade 11 is rotating forward and backward. Wash water at the bottom of the tank 10 is poured from the nozzle 34. While the rotary blades 11 and the circulation pump 16 are stopped, the tank water supply electromagnetic valve 4a is opened with reference to the detection signal of the water level sensor 21 to supply water. By repeating this operation a plurality of times, the high-concentration washing water is adapted to the laundry.
本洗い工程Ｓ５では、洗濯兼脱水槽９を静止させた状態で回転翼１１を正逆回転させながら循環ポンプ１６を運転して、外槽１０の底部に溜まった洗い水をノズル３４から洗濯物に降り掛ける。また、循環ポンプ１６の運転を停止して洗い水の循環を止めた状態で、回転翼１１を正逆回転させる布ほぐしも行う。本工程では、こうした洗い水の循環と布ほぐしを数回繰り返す。 In the main washing step S5, the circulation pump 16 is operated while rotating the rotary blade 11 in the forward and reverse directions while the washing / dehydrating tub 9 is stationary, and the washing water collected at the bottom of the outer tub 10 is washed from the nozzle 34. Get down to. Further, cloth unraveling that rotates the rotor blade 11 forward and backward is performed in a state where the operation of the circulation pump 16 is stopped and the circulation of the washing water is stopped. In this step, the washing water circulation and cloth unraveling are repeated several times.
洗い運転からすすぎ１運転へ移行すると、まず、脱水工程Ｓ６が行われる。本工程では、排水弁１５を開いて外槽１０の底部に溜まっている洗い水を排水する。 When shifting from the washing operation to the rinsing 1 operation, first, the dehydration step S6 is performed. In this step, the drain valve 15 is opened to drain the wash water accumulated at the bottom of the outer tub 10.
次に、脱水工程Ｓ７では、洗濯兼脱水槽９と回転翼１１を一体的に一方向に回転させて洗濯物に含まれている洗い水を遠心脱水する。このときの洗濯兼脱水槽９の回転速度は、後述する最終脱水における回転速度（９００ｒｐｍ以上）と同様に設定し、高い脱水率を実現する。 Next, in the dewatering step S7, the washing and dewatering tank 9 and the rotary blade 11 are integrally rotated in one direction to centrifugally dewater the wash water contained in the laundry. The rotational speed of the washing and dewatering tub 9 at this time is set similarly to the rotational speed (900 rpm or more) in the final dehydration described later, and a high dehydration rate is realized.
回転シャワー工程Ｓ８では、洗濯兼脱水槽９の回転を停止させずに減速し、１０〜１３０ｒｐｍ（望ましは３５ｒｐｍ程度）で緩速運転させながら、排水弁１５を開弁した状態で槽内給水電磁弁４ａを開弁し、水道水を散水口３５から回転翼１１上の洗濯物に降り掛けるように散布する。仮に、高い回転速度で洗濯兼脱水槽９が回転しているときに散水口３５からシャワーを散水しても、洗濯物に当たった水が回転の勢いで弾かれて洗濯物のない場所へ飛んで行く可能性がある。しかし、本実施例のような低い回転速度で洗濯兼脱水槽９を回転することにより、水跳ねを抑えて洗濯物に満遍なく水を当てることができ、少ない水であってもすすぎ効果が向上する。 In the rotary shower step S8, the water supply in the tank is performed while the drain valve 15 is opened while decelerating without stopping the rotation of the washing and dewatering tank 9 and slowly operating at 10 to 130 rpm (preferably about 35 rpm). The electromagnetic valve 4 a is opened, and tap water is sprayed from the water spout 35 so as to fall on the laundry on the rotary blade 11. Even if the shower and sprinkling tub 9 is rotating at a high rotation speed, even if the shower is sprinkled from the sprinkling port 35, the water hitting the laundry is repelled by the rotational force and flies to a place where there is no laundry. There is a possibility to go in. However, by rotating the washing and dewatering tub 9 at a low rotation speed as in this embodiment, water splash can be suppressed and water can be uniformly applied to the laundry, and the rinsing effect is improved even with a small amount of water. .
本実施例では、給水カバー３６を上述のような構造に改良することで、従来と比べて広い領域に満遍なく散水が可能となっているため、すすぎ効果はより一層向上する。 In this embodiment, the water supply cover 36 is improved to the above-described structure, so that water can be uniformly distributed over a wide area as compared with the conventional case, so that the rinsing effect is further improved.
続いて、浸透すすぎ工程Ｓ９では、槽内給水電磁弁４ａを閉弁し、散布した水を洗濯物の内部まで十分に浸み込ませる。具体的には、排水弁１５を開弁したまま、洗濯兼脱水槽９を停止せず、回転シャワー工程Ｓ８における洗濯兼脱水槽９と同じ回転速度または一次共振より低い回転速度で回転させる。仮に、浸透すすぎの際に、洗濯兼脱水槽９を停止させていると、一部の洗濯物だけに集中して水が浸み込んで局所的に重くなり、アンバランスを生じさせ、脱水の中断処理が働く可能性がある。しかし、本実施例のように、１０〜１３０ｒｐｍ程度の回転速度で洗濯兼脱水槽９を回転させることで、そのようなアンバランスの発生を抑制できる。また、本実施例の浸透すすぎでは、洗濯物に散布した水を直ぐに脱水せず、洗濯物の繊維の内部まで散布した水を十分に行き渡らせるとともに、洗濯物の繊維の内部に含まれている洗剤分を散布した水に溶け出させる効果がある。 Subsequently, in the permeation rinsing step S9, the tank water supply electromagnetic valve 4a is closed, and the sprayed water is sufficiently immersed into the laundry. Specifically, the washing / dehydrating tub 9 is not stopped while the drain valve 15 is opened, and is rotated at the same rotational speed as the washing / dehydrating tub 9 in the rotary shower step S8 or at a rotational speed lower than the primary resonance. If the washing and dehydrating tub 9 is stopped at the time of osmotic rinsing, water concentrates only on a part of the laundry and becomes locally heavy, causing imbalance, Interruption processing may work. However, the occurrence of such an imbalance can be suppressed by rotating the washing and dewatering tub 9 at a rotational speed of about 10 to 130 rpm as in this embodiment. Moreover, in the osmotic rinse of the present embodiment, the water sprayed on the laundry is not immediately dehydrated, and the water sprayed to the inside of the laundry fibers is sufficiently distributed and contained in the laundry fibers. It has the effect of dissolving in water sprayed with detergent.
その後、脱水工程Ｓ１０を行い、洗濯兼脱水槽９を９００ｒｐｍ以上で高速回転させ、洗濯物に含まれる水分を除去する。 Thereafter, a dehydration step S10 is performed, and the washing and dewatering tank 9 is rotated at a high speed of 900 rpm or more to remove moisture contained in the laundry.
本実施例におけるすすぎ１運転は、回転シャワー工程Ｓ８における散水構造と浸透すすぎ工程Ｓ９における運転制御とを改良することにより、すすぎ効果が格段に向上するため、従来と比べて回転シャワーの回数を１回に減らすことが可能となり、使用する水の量を減らして節水を実現できる。また、すすぎ１運転の全体の時間も短縮でき、消費電力量を低減することも可能となる。 In the first rinsing operation in this embodiment, the rinsing effect is remarkably improved by improving the watering structure in the rotary shower step S8 and the operation control in the infiltration rinsing step S9. This makes it possible to reduce the amount of water used and reduce the amount of water used, thereby saving water. In addition, the entire time of one rinsing operation can be shortened, and the power consumption can be reduced.
さらに、本実施例におけるすすぎ１運転は、脱水工程Ｓ７から脱水工程Ｓ１０までを、洗濯兼脱水槽９の回転を停止させることなく連続で運転するため、洗濯物のバランスが崩れることもなく、安全のために脱水運転を中断させる処理の実行を抑制できる。 Furthermore, in the first rinsing operation in the present embodiment, since the dehydration step S7 to the dehydration step S10 are continuously operated without stopping the rotation of the washing and dehydrating tub 9, the balance of the laundry is not disturbed, and safety is ensured. Therefore, it is possible to suppress the execution of the process for interrupting the dehydration operation.
すすぎ１運転からすすぎ２運転へ移行すると、ためすすぎを行うべく、すすぎ給水工程Ｓ１１を実行する。本工程では、排水弁１５を閉弁し、槽内給水電磁弁４ａを開弁して水道水を洗濯兼脱水槽９内へ供給するとともに、仕上剤給水電磁弁４ｃを開弁することで、仕上剤投入室に仕上剤があった場合は、仕上剤を水道水とともに外槽１０の底部へ供給する。 When the rinsing 1 operation is shifted to the rinsing 2 operation, the rinsing water supply step S <b> 11 is executed in order to perform rinsing. In this step, the drain valve 15 is closed, the tank water supply electromagnetic valve 4a is opened to supply tap water into the washing and dewatering tank 9, and the finish agent water supply electromagnetic valve 4c is opened. When there is a finishing agent in the finishing agent charging chamber, the finishing agent is supplied to the bottom of the outer tub 10 together with tap water.
次に、攪拌工程Ｓ１２では、外槽１０にすすぎ水を溜めたまま、洗濯兼脱水槽９を静止させた状態で、回転翼１１を正逆回転させながら、循環ポンプ１６を運転してノズル３４からすすぎ水を散布することにより、洗濯物を攪拌しつつすすぐ。 Next, in the stirring step S12, the rinsing water is stored in the outer tub 10 and the washing / dehydrating tub 9 is kept stationary, while the rotary blade 11 is rotated forward and backward, the circulation pump 16 is operated to operate the nozzle 34. Rinse the laundry while sprinkling with rinsing water.
すすぎ２運転が終了し、脱水運転へ移行すると、まず排水工程Ｓ１３が実行される。本工程では、排水弁１５を開弁し、外槽１０内のすすぎ水を排水する。 When the two rinsing operations are completed and the process proceeds to the dehydrating operation, the draining step S13 is first executed. In this step, the drain valve 15 is opened and the rinse water in the outer tub 10 is drained.
その後の脱水工程Ｓ１４では、洗濯兼脱水槽９と回転翼１１を一体的にして一方向に９００ｒｐｍ以上の高速回転させるように、洗濯脱水駆動装置を運転して洗濯兼脱水槽９内の洗濯物を遠心脱水するように行う。この最終脱水の運転時間は、所望の脱水率が得られる時間に設定する。 In the subsequent dehydration step S14, the laundry in the washing / dehydrating tub 9 is operated by operating the washing / dehydrating driving device so that the washing / dehydrating tub 9 and the rotary blade 11 are integrally rotated at a high speed of 900 rpm or more in one direction. Do so as to spin-dry. The operation time for the final dehydration is set to a time for obtaining a desired dehydration rate.
洗濯から乾燥までを行う洗濯乾燥コースが設定されている場合は、乾燥工程Ｓ１５を実行する。本工程は、排水弁１５を開弁したまま、洗濯兼脱水槽９を静止させた状態で回転翼１１を正逆回転させながら、乾燥ダクト２２の途中に設けた送風ファン１９を運転することによって外槽９内の空気を通水通気口１０ｂから乾燥ダクト２２内に吸い出し、この乾燥ダクト２２内を通過するときに乾燥ダクト２２内に設置した除湿機構２２ｂから流れ落ちる冷却水に触れさせて冷却除湿した後にリントフィルタを通して糸屑を捕集し、ヒータ２０によって加熱した後に温風吹き出し口２２ａから洗濯兼脱水槽２内に吹き込むことにより行う。乾燥は、温度センサ２６により温風の温度を監視しながら実行し、温度変化の割合が所定の値になったときに終了する。 When the washing / drying course for performing from washing to drying is set, the drying step S15 is executed. This step is performed by operating the blower fan 19 provided in the middle of the drying duct 22 while rotating the rotary blade 11 in the forward and reverse directions while the washing and dewatering tub 9 is stationary with the drain valve 15 opened. The air in the outer tub 9 is sucked into the drying duct 22 from the water vent 10b, and when passing through the drying duct 22, the cooling water flowing down from the dehumidifying mechanism 22b installed in the drying duct 22 is brought into contact with the cooling dehumidification. After that, the lint is collected through a lint filter, heated by the heater 20, and then blown into the washing and dewatering tub 2 from the warm air outlet 22a. Drying is performed while monitoring the temperature of the hot air by the temperature sensor 26, and is completed when the rate of temperature change reaches a predetermined value.
なお、本実施例では、乾燥機能を有する洗濯乾燥機について説明したが、乾燥機能を有しない洗濯機であっても良い。 In addition, although the present Example demonstrated the washing-drying machine which has a drying function, the washing machine which does not have a drying function may be sufficient.
