JP 09-215893 (pages 3 to 5, FIG. 1)

従来のドラム式洗濯機では、回転ドラムの軸心線上に洗濯物出入口の中心及び扉体の中心が略一致するように配置され、水槽の正面側に形成される洗濯物出入口の開口径は回転ドラムの直径より小さく形成されている。回転ドラムの直径は配置スペースの許す限り大きい方が望ましいが、洗濯物出入口の開口径は扉体によって開かれる洗濯機筐体の開閉口の直径に対応して最適の直径があり、扉体を大きくすることによるドラム式洗濯機の設置場所の制限などの理由から扉体の直径に対応する開口径に形成される。   In a conventional drum-type washing machine, the center of the laundry doorway and the center of the door body are substantially aligned on the axis of the rotating drum, and the opening diameter of the laundry doorway formed on the front side of the aquarium is rotating. It is formed smaller than the diameter of the drum. The diameter of the rotating drum is preferably as large as the space available, but the opening diameter of the laundry entrance / exit has an optimum diameter corresponding to the diameter of the opening / closing opening of the washing machine casing opened by the door body. It is formed in an opening diameter corresponding to the diameter of the door body for reasons such as limiting the installation location of the drum type washing machine by increasing the size.

このように回転ドラムの軸心線上に洗濯物出入口の中心及び扉体の中心が概略一致するように配置され、洗濯物出入口の開口径が回転ドラムの直径より小さく形成されていることにより、扉体を開いたとき回転ドラムの正面側に死角となる部分ができ、そこに存在する洗濯物の取り出しを忘れがちになる問題や、回転ドラムから洗濯物を取り出し難い問題点があった。   In this way, the center of the laundry doorway and the center of the door body are arranged on the axis of the rotary drum so that the center of the door is substantially coincident, and the opening diameter of the laundry doorway is formed smaller than the diameter of the rotary drum. When the body was opened, there was a blind spot on the front side of the rotating drum, and there was a problem that it was easy to forget to take out the laundry present, and there was a problem that it was difficult to take out the laundry from the rotating drum.

本発明が目的とするところは、回転ドラムの直径より小さく形成せざるを得ない洗濯物出入口からの洗濯物の出し入れを容易にする構造を備えるとともに、回転ドラムの開口端からその一部が飛び出した洗濯物が回転ドラムと水槽との間に噛み込む状態になることが防止できるドラム式洗濯機を提供することにある。   The object of the present invention is to provide a structure for facilitating the loading and unloading of the laundry from the laundry doorway which must be formed smaller than the diameter of the rotating drum, and a part of the structure protrudes from the opening end of the rotating drum. Another object of the present invention is to provide a drum-type washing machine capable of preventing the laundry from being caught between the rotating drum and the water tub.

上記目的を達成するための本発明に係るドラム式洗濯機は、洗濯機筐体の正面側に開口部を有し有底円筒形に形成された回転ドラムと、前記洗濯機筐体内に配設されるとともに内部に前記回転ドラムを回転可能に収容し前記回転ドラムの開口部と同一方向になるように開口端を有する有底円筒形の水槽本体と、前記回転ドラム内の洗濯物を前記回転ドラムの開口部を介して出し入れするための円形の洗濯物出入口を前面に有し前記水槽本体の開口端に接合される水槽蓋体と、前記洗濯機筐体に取り付けられ中心位置を前記洗濯物出入口の中心位置と略一致させて前記洗濯物出入口を開閉する扉体と、前記水槽本体に取り付けられ前記回転ドラムを回転駆動するドラム駆動モータとを備え、前記回転ドラムの回転中心は、前記洗濯機筐体の正面側から背面側に向けて下向き傾斜となるように構成し、前記円形の洗濯物出入口は、その中心を前記回転ドラムの回転中心から上方向に偏心させるとともに、前記回転ドラムの開口部より小さい直径に形成し、前記水槽蓋体の前面の裏面で前記円形の洗濯物出入口の周縁部位には、前記水槽蓋体が前記回転ドラムの開口部を覆う下方部分に、前記回転ドラムの開口部を介して前記回転ドラム内に向けて突出する三日月状の噛み込み防止突起を前記回転ドラムの開口部の周縁部から所定の隙間を有して設けることで、前記三日月状の噛み込み防止突起が、前記回転ドラムの開口部の先端部と前記水槽蓋体の前面の間を覆うように構成したことを特徴とする。 In order to achieve the above object, a drum-type washing machine according to the present invention includes a rotating drum having an opening on the front side of a washing machine casing and formed into a bottomed cylindrical shape, and is disposed in the washing machine casing. The rotating drum is rotatably accommodated therein, and has a bottomed cylindrical water tank main body having an opening end so as to be in the same direction as the opening of the rotating drum, and the laundry in the rotating drum is rotated. A water tank lid that is provided with a circular laundry entrance for taking in and out through the opening of the drum on the front surface and is joined to the opening end of the water tank body, and the laundry that is attached to the washing machine casing at the center position A door body that opens and closes the laundry entrance and exit substantially in line with the center position of the entrance and exit, and a drum drive motor that is attached to the water tub body and that rotationally drives the rotary drum. Front of machine casing From toward the back side configured to be downwardly inclined, laundry entrance of the circular, as well is decentered upwardly to its center from the rotation center of the rotary drum, the smaller diameter than the opening of the rotary drum And forming the circular laundry doorway at the peripheral portion of the front surface of the water tank lid and the lower portion of the water tank cover covering the opening of the rotating drum via the opening of the rotating drum. The crescent-shaped biting prevention protrusion protruding toward the inside of the rotating drum is provided with a predetermined gap from the peripheral edge of the opening of the rotating drum, so that the crescent-shaped biting prevention protrusion is the rotation It is configured to cover between the front end of the opening of the drum and the front surface of the water tank lid.

上記構成によれば、回転ドラムは水槽内に略同心に収容され、水槽に設けられた洗濯物出入口はその中心を回転ドラムの中心から上方向に偏心させて形成され、洗濯機筐体に設けられた扉体は洗濯物出入口と中心を略一致させて設け、さらに、回転ドラムの開口端が正面側で上向きとなる傾斜角度に回転軸心方向を傾斜させて水槽内に配設した構成としているので、扉体を開いて洗濯物出入口を通して回転ドラムに対して洗濯物を出し入れするとき、上方から見下ろすように回転ドラム内を覗く使用者の視線方向から回転ドラム内の下部が見やすく、回転ドラム内の上部も洗濯物出入口及び扉体の中心が上方向に偏心していることから見やすくなる。従って、扉体から回転ドラム内を覗く視線に死角が発生し難く、死角位置にある洗濯物の取り出しをわすれたりすることがなく、使い勝手のよいドラム式洗濯機に構成することができる。さらに、回転ドラムの開口端からその一部が飛び出した洗濯物が回転ドラムと水槽との間に噛み込む状態になることが防止できる。 According to the above configuration, the rotating drum is accommodated substantially concentrically in the water tub, and the laundry doorway provided in the water tub is formed with its center deviated upward from the center of the rotating drum, and is provided in the washing machine casing. The door body is provided so that the center of the door is substantially coincident with the center of the laundry , and the rotating drum is disposed in the water tank so that the opening end of the rotating drum is inclined upward at the front side. Therefore, when opening and closing the door body and putting laundry in and out of the rotating drum through the laundry doorway, the lower part in the rotating drum is easy to see from the direction of the user's line of sight as if looking down from above the rotating drum. The upper part in the drum is also easy to see because the laundry doorway and the center of the door are eccentric in the upward direction. Therefore, it is difficult to generate a blind spot in the line of sight when looking into the rotating drum from the door body, and it is possible to configure a drum-type washing machine that is easy to use without forgetting to take out the laundry at the blind spot position. Furthermore, it is possible to prevent the laundry, part of which protrudes from the opening end of the rotating drum, from entering between the rotating drum and the water tub.

本発明によれば、開口径に制約がある扉体と、それに対応する開口径となる洗濯物出入口であっても、それより大きな開口径を有する回転ドラム内に対して死角となる部分を少なくすることができ、洗濯物の取り出し忘れを生じさせることが少なく、使い勝手のよいドラム式洗濯機に構成することができるとともに、回転ドラムの開口端からその一部が飛び出した洗濯物が回転ドラムと水槽との間に噛み込む状態になることが防止できる。   According to the present invention, even in a door body with a limited opening diameter and a laundry doorway with an opening diameter corresponding to the door body, the number of blind spots in the rotary drum having a larger opening diameter is reduced. It is possible to make a drum-type washing machine that is easy to use and less likely to forget to take out the laundry, and the laundry that partially protrudes from the opening end of the rotating drum is the rotating drum. It is possible to prevent a state of being bitten between the water tank.

図１は、実施形態に係るドラム式洗濯機１の要部構成を示すもので、洗濯機筐体２内に図示しないサスペンション構造により水槽３が支持され、この水槽３内には有底円筒形に形成された回転ドラム５がその回転軸方向Ｒを水平方向Ｈから角度θに傾斜させて配置されている。   FIG. 1 shows a configuration of a main part of a drum-type washing machine 1 according to an embodiment. A water tank 3 is supported in a washing machine housing 2 by a suspension structure (not shown), and the water tank 3 has a bottomed cylindrical shape. The rotating drum 5 formed in the above is arranged with its rotational axis direction R inclined from the horizontal direction H to an angle θ.

前記回転ドラム５は、有底円筒形の開口部側を洗濯機筐体２の正面側に、底面側を洗濯機筐体２の背面側にして、回転軸心Ｒが正面側から背面側に向けて角度θで下向き傾斜となるようにして水槽３内に配置され、水槽３の背面に取り付けられたドラム駆動モータ４によって回転駆動される。水槽３は、有底円筒形に形成された水槽本体３ａの開口端に、洗濯物を回転ドラム５内から出し入れするための洗濯物出入口１１を形成した水槽蓋体３ｂを接合して構成され、この洗濯物出入口１１に対向させて洗濯機筐体２の正面側に形成された傾斜面２ａには開閉自在に扉体８が設けられている。この扉体８を開くことにより回転ドラム５に対して洗濯物を出し入れすることができ、扉体８の一部あるいは全体を透明体によって形成することにより、回転ドラム５内を外部から透視することができる。尚、洗濯物出入口１１の周囲には、柔軟な弾性体によって形成されたベローズ１５が配設され、扉体８を閉じると、その内面にベローズ１５の一端が圧接し、回転ドラム５の回転に伴って飛散する水が水槽３内から外に飛び出すのを防止している。   The rotating drum 5 has a bottomed cylindrical opening side on the front side of the washing machine housing 2 and a bottom surface on the back side of the washing machine housing 2 so that the rotation axis R is from the front side to the back side. It is arranged in the water tank 3 so as to be inclined downward at an angle θ and is driven to rotate by a drum drive motor 4 attached to the back surface of the water tank 3. The water tank 3 is configured by joining a water tank lid 3b having a laundry entrance 11 for taking in and out the laundry from the rotating drum 5 to the opening end of a water tank body 3a formed in a bottomed cylindrical shape, A door body 8 is provided on an inclined surface 2a formed on the front side of the washing machine casing 2 so as to face the laundry entrance 11 and can be opened and closed. Laundry can be taken in and out of the rotating drum 5 by opening the door body 8, and the inside of the rotating drum 5 is seen through from the outside by forming a part or the whole of the door body 8 with a transparent body. Can do. A bellows 15 formed of a flexible elastic body is disposed around the laundry entrance 11, and when the door body 8 is closed, one end of the bellows 15 comes into pressure contact with the inner surface of the door body 8 to rotate the rotating drum 5. The accompanying water is prevented from jumping out of the water tank 3.

上記構成のように回転ドラム５が傾斜配置され、その開口部に対向させて洗濯機筐体２に扉体８を設けることにより、扉体８を開いて回転ドラム５に対して洗濯物を出し入れする作業に際して腰を屈める具合が少なくてすみ、また、ドラム式洗濯機１の正面に余裕のある空間を確保する必要もなく、従来の縦型洗濯機を設置していた洗面所などの狭いスペースにドラム式洗濯機１を設置することが可能となり、狭い日本の住環境にも適合するドラム式洗濯機１に構成することができる。   As described above, the rotary drum 5 is inclined, and the door body 8 is provided in the washing machine casing 2 so as to face the opening, thereby opening the door body 8 and putting laundry into and out of the rotary drum 5. It is not necessary to bend down at the time of the work to be performed, and it is not necessary to secure a sufficient space in front of the drum type washing machine 1, and it is narrow such as a toilet where a conventional vertical washing machine is installed. The drum type washing machine 1 can be installed in a space, and the drum type washing machine 1 can be configured to be suitable for a small Japanese living environment.

前記洗濯物出入口１１の形成位置は、その中心位置が回転ドラム５の回転軸心Ｒから上方向に偏心させて形成されている。この洗濯物出入口１１に対向させ、中心位置を洗濯物出入口１１の中心線上に略一致させて扉体８が設けられている。扉体８の直径はドラム式洗濯機１の設置場所の制約などから最適の寸法があり、回転ドラム５の開口径より小さくしている。また、扉体８の直径に対応して洗濯物出入口１１の直径も設定されるので、やはり回転ドラム５の開口径より小さくしている。上述のように洗濯物出入口１１及び扉体８をその中心位置が回転ドラム５の回転軸心から上方向に偏った位置に設けると、扉体８を開いて洗濯物出入口１１を通して回転ドラム５の内部を覗いたとき、死角となる部分が少なくなり、回転ドラム５内に収容した洗濯物が広範囲にわたって見えるので、洗濯物の取り出し忘れなどが生じ難くなる。特に、本実施形態に係るドラム式洗濯機１のように、回転ドラム５を傾斜配置し、回転ドラム５の傾斜角度に対応させた傾斜面２ａに扉体８を設けた構成においては、より広範囲に回転ドラム５の内部を見ることができる。   The laundry entrance / exit 11 is formed such that the center position thereof is decentered upward from the rotational axis R of the rotary drum 5. A door body 8 is provided so as to face the laundry entrance 11 and the center position thereof is substantially coincident with the center line of the laundry entrance 11. The diameter of the door body 8 has an optimum dimension due to restrictions on the installation place of the drum type washing machine 1 and is smaller than the opening diameter of the rotating drum 5. Further, since the diameter of the laundry entrance / exit 11 is also set corresponding to the diameter of the door body 8, it is also made smaller than the opening diameter of the rotating drum 5. As described above, when the laundry doorway 11 and the door body 8 are provided at positions where their center positions are offset upward from the rotational axis of the rotary drum 5, the door body 8 is opened and the laundry doorway 11 passes through the laundry doorway 11. When looking inside, the number of blind spots is reduced, and the laundry stored in the rotating drum 5 can be seen over a wide range, so that it is difficult to forget to take out the laundry. In particular, as in the drum-type washing machine 1 according to the present embodiment, in a configuration in which the rotating drum 5 is inclined and the door body 8 is provided on the inclined surface 2 a corresponding to the inclination angle of the rotating drum 5, a wider range. The inside of the rotary drum 5 can be seen.

回転ドラム５を傾斜配置する傾斜角度θは、本願発明者らが様々な調査研究を行った結果、θ＝３０±５度であるとの結論を得た。この傾斜角度θ＝３０±５度に回転ドラム５を傾斜配置することにより、子供（幼児を除く）から大人までの身長差があっても、車椅子を使用する障害者であっても、洗濯物の出し入れの作業が最も行い易い状態が得られる。この回転ドラム５の傾斜配置に加えて洗濯物出入口１１及び扉体８の中心位置が回転ドラム５の回転軸心Ｒから上方向に偏っていることにより、洗濯物の出し入れが容易になるばかりでなく、透明な扉体８から洗濯の各工程における動作状態も観察しやすくなる。   As a result of various investigations and studies by the inventors of the present application, the conclusion that θ = 30 ± 5 degrees has been obtained. Even if there is a height difference from a child (excluding infants) to an adult or a disabled person who uses a wheelchair by arranging the rotating drum 5 at an inclination angle θ = 30 ± 5 degrees, the laundry It is possible to obtain a state in which the operation of loading and unloading is most easily performed. In addition to the inclined arrangement of the rotating drum 5, the center positions of the laundry entrance 11 and the door body 8 are biased upward from the rotation axis R of the rotating drum 5. In addition, it becomes easy to observe the operation state in each process of washing from the transparent door body 8.

しかし、回転ドラム５の開口径より洗濯物出入口１１の開口径が小さく、回転ドラム５の回転軸心Ｒから洗濯物出入口１１の中心位置が一方に偏っていると、図示するように回転ドラム５の開口端に水槽蓋体３ｂの下方がオーバーラップすることになる。この状態で回転ドラム５の開口端から洗濯物の一部が飛び出た場合に、回転ドラム５の回転に伴って飛び出た部分が回転ドラム５と水槽蓋体３ｂとの間に噛み込んでしまうことがある。   However, if the opening diameter of the laundry entrance / exit 11 is smaller than the opening diameter of the rotating drum 5 and the center position of the laundry entrance / exit 11 is biased to one side from the rotation axis R of the rotating drum 5, the rotating drum 5 is illustrated as shown in the figure. The lower end of the water tank lid 3b overlaps the opening end of the water tank. When a part of the laundry jumps out from the opening end of the rotating drum 5 in this state, the part popping out with the rotation of the rotating drum 5 is caught between the rotating drum 5 and the water tank lid 3b. There is.

この洗濯物の噛み込みを防止するために、水槽蓋体３ｂの回転ドラム５の開口端にオーバーラップする部分に、回転ドラム５内に向けて突出する噛み込み防止突起１６が三日月状の形状に設けられている。   In order to prevent this laundry from being caught, a biting prevention protrusion 16 protruding toward the inside of the rotating drum 5 is formed in a crescent shape at a portion overlapping the opening end of the rotating drum 5 of the water tank lid 3b. Is provided.

図２は、水槽蓋体３ｂを内側から見た状態で示すもので、洗濯物出入口１１が中心（回転ドラム５の中心）から上方向に偏った位置に形成され、この洗濯物出入口１１の偏り方向と逆の方向を中心とする噛み込み防止突起１６が回転ドラム５内に向けて突出するように三日月状に設けられている。   FIG. 2 shows the water tank lid 3b as viewed from the inside. The laundry entrance 11 is formed at a position offset upward from the center (center of the rotating drum 5). The biting prevention protrusion 16 centering on the direction opposite to the direction is provided in a crescent shape so as to protrude into the rotating drum 5.

この噛み込み防止突起１６があることによって、回転ドラム５内から飛び出た洗濯物の一部が回転ドラム５と水槽蓋体３ｂとの間に入り込まないので、洗濯物出入口１１の形成位置を偏心させたことによる洗濯物の噛み込みが防止できる。   The presence of the biting prevention protrusion 16 prevents a part of the laundry that has jumped out of the rotating drum 5 from entering between the rotating drum 5 and the water tank lid 3b, thereby decentering the position where the laundry doorway 11 is formed. It is possible to prevent the laundry from being bitten.

上記のように回転ドラム５を傾斜配置すると、洗濯物を出し入れする作業が容易になることや、回転ドラム５内に給水された水が背面側に溜まって少ない水量でも深い貯水状態が得られる利点がある反面、回転ドラム５内に収容した洗濯物は、最も低い位置となる底面側の下部に集まり、回転ドラム５を回転させると更に洗濯物を底面側に集めてしまう弊害が生じ、洗濯物個々の位置を入れ替えてすべての洗濯物に満遍なく洗浄力を与える作用が不完全になる課題が発生するが、本実施形態に係るドラム式洗濯機１においては、ドラム駆動モータ４による回転ドラム５の回転駆動を制御することにより洗濯物の位置入れ替えがなされる構成とし、あるいは回転ドラム５の内周壁に設けた攪拌突起９の形状により洗濯物の位置入れ替えがなされるように構成している。   When the rotating drum 5 is inclined as described above, the work of putting in and out the laundry is facilitated, and the water stored in the rotating drum 5 is accumulated on the back side, so that a deep water storage state can be obtained even with a small amount of water. On the other hand, the laundry stored in the rotating drum 5 gathers in the lower part on the bottom surface side, which is the lowest position, and if the rotating drum 5 is rotated, the laundry is further collected on the bottom surface side. Although the problem that the action of uniformly applying the cleaning power to all the laundry by replacing the individual positions occurs is incomplete, in the drum type washing machine 1 according to the present embodiment, the rotation of the rotating drum 5 by the drum driving motor 4 is generated. The position of the laundry is changed by controlling the rotation drive, or the position of the laundry is changed by the shape of the stirring protrusion 9 provided on the inner peripheral wall of the rotary drum 5.
