It can be suppressed.

本発明のドラム式洗濯機によれば、開閉蓋および出し入れ口が洗濯機筐体の前面に対し後傾していて、洗濯機筐体の前面の角度にかかわらず、回転ドラムの傾斜姿勢と併せ、洗濯物の出し入れ、外部からの洗濯物の透視に便利で使用しやすいものとなるし、洗濯機筐体の前面の角度は垂直、後傾を含めた選択の自由度が高まるので、各種用途や要求に対応しやすい。併せ、ボディーパネルが形成する前面からの凹陥部は、前記前面から傾斜した出し入れ口を開口させる底部を持った深絞り形状部となるが、その開口側と底部側とがボディーパネルを分割した枠状のボディーパネルと環状のボディーパネルとで分担、形成して一体化するので、深絞り加工を回避して容易かつ低コストで実現し、しかもカバーパネルで覆うだけで外装し外観が整えられる。   According to the drum type washing machine of the present invention, the opening / closing lid and the entrance / exit are inclined rearward with respect to the front surface of the washing machine casing, and the tilting posture of the rotating drum is combined regardless of the angle of the front surface of the washing machine casing. It is convenient and easy to use for putting in and taking out laundry and seeing laundry from the outside, and the angle of the front surface of the washing machine housing is vertical, and the freedom of choice including backward tilting is increased, so it can be used for various purposes It is easy to respond to requests. In addition, the recessed portion from the front surface formed by the body panel is a deep-drawn shape portion having a bottom portion that opens an inlet / outlet inclined from the front surface, but the opening side and the bottom portion side are divided into frames. Since it is shared, formed, and integrated by an annular body panel and an annular body panel, it can be realized easily and at a low cost by avoiding deep drawing, and the exterior can be trimmed just by covering with a cover panel.

上記に加え、さらに、枠状のボディーパネルおよび環状のボディーパネルが、それらの凹陥部開口側の後端部内向きフランジ部と凹陥部底部側の前端部外向きフランジ部との重ねスポット溶接にて、必要強度を満足して簡単に一体化でき、特に構造の複雑化やコスト上昇の原因にはならない。   In addition to the above, a frame-shaped body panel and an annular body panel are also formed by overlapping spot welding of the rear end inward flange portion on the recessed portion opening side and the front end outward flange portion on the bottom portion of the recessed portion. , It can be easily integrated to satisfy the required strength, and it will not cause complicated structure and cost increase.

上記に加え、さらに、厚い環状のボディーパネルと薄い枠状のボディーパネルとの、板厚の組み合わせ、および、それらの重ねスポット溶接構造などの一体化構造と立体形状、が合わさって必要強度を満足し、面積の大きな枠状のボディーパネル板厚を薄くできた分だけ洗濯機筐体が軽量化し低コスト化する。   In addition to the above, the combination of plate thickness of thick annular body panel and thin frame-like body panel, and the integrated structure such as lap spot welded structure and solid shape meet the required strength. However, the washing machine housing becomes lighter and lower in cost by the thickness of the large body-like body panel.

上記に加え、さらに、厚い側の環状のボディーパネルを取り付け座として開閉関与器具類を装備するので、十分な強度で取り付け安定に支持できる。また、カバーパネルを前部から取り外して環状のボディーパネルに前部から装備した開閉関与器具類を露出させられるので、それら開閉関与器具類の各種メンテナンスが前部側からの作業だけで簡単かつ容易に行える。   In addition to the above, since the opening / closing-related instruments are equipped with an annular body panel on the thick side as a mounting seat, the mounting can be supported stably with sufficient strength. In addition, since the cover panel can be removed from the front to expose the opening / closing equipment mounted on the annular body panel from the front, various maintenance of these opening / closing equipment can be done easily and easily only from the front side. Can be done.

上記に加え、さらに、環状のカバーパネルは強度の問題がなく樹脂製として、ボディーパネルの上部に設けた樹脂製で操作・表示面をなす強度の要らないトップマークユニットと対向させることで、双方が同じ質感で、強度上金属製とするボディーパネルとは差別化し、かつ、樹脂成形によって、金属板の折り曲げのような影響なしに隙間の有無など対向、突き合わせ条件を自由に選択、設定し、樹脂製２部材が連続した外観を含む最適外観が得られる。   In addition to the above, the annular cover panel is made of resin without any problem of strength, and it is made by facing the top mark unit that is made of resin and is used for operation and display on the top of the body panel. Is different from the body panel made of metal with the same texture and strength, and by resin molding, facing and matching conditions such as the presence or absence of gaps can be freely selected and set without the influence of bending metal plates, An optimum appearance including a continuous appearance of two resin members is obtained.

上記に加え、さらに、洗濯機筐体の前面が水平方向にほぼ垂直であることにより、ビルトイン使用するような場合の対象家具の同じく垂直な前面に揃えられるので、外観が整いシステム化できる。   In addition to the above, since the front surface of the washing machine casing is substantially vertical in the horizontal direction, it is aligned with the same vertical front surface of the target furniture in the case of built-in use.

上記に加え、さらに、トップマークユニットの前面が後部側に若干傾斜して、ビルトイン対象家具の垂直な前面から、あまり窪むことなく、従って、対象家具との前面の揃い度を余り崩さずに、ユーザーの自然な視線に対する傾きを抑えて視認しやすく操作しやすいものとすることができる。   In addition to the above, the front surface of the top mark unit is slightly inclined toward the rear side, so that it does not dent much from the vertical front surface of the built-in target furniture, and therefore, the degree of alignment of the front surface with the target furniture is not significantly collapsed. In addition, it is possible to suppress the inclination of the user with respect to the natural line of sight and make it easy to view and operate.

以下本発明の実施の形態に係るドラム式洗濯機につき図１〜図７を参照しながら説明し、本発明の理解に供する。なお、以下の説明は本発明の具体例であって、特許請求の範囲の記載の内容を限定するものではない。   Hereinafter, a drum type washing machine according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7 for understanding of the present invention. In addition, the following description is a specific example of this invention, Comprising: The content of description of a claim is not limited.

図１、図２に示す本実施の形態のドラム式洗濯機１は、図１に示すように、有底円筒形に形成された回転ドラム２を、開口する正面側から底部となる背面側に向けて回転軸２０の方向が水平方向から下向き傾斜となるようにして、サスペンションによりフローティング支持した水槽３内に設置し、洗濯機筐体４の前部に設けた開閉蓋５を開いて洗濯物を回転ドラム２に収容しモータ６で回転ドラム２を駆動することにより洗濯工程、すすぎ工程、脱水工程の少なくとも１つが行える。開閉蓋５は図１〜図３に示すように、洗濯物を外部から透視する透明なガラス板１１を嵌め付けた窓７を有した蓋本体８と、この蓋本体８の前面に当てがわれた前域または周辺を残した必要透視域を透明とした蓋カバー９とからなっている。蓋本体８は、蓋枠８ａがポリプロピレンで成形され、裏枠８ｂがさらに耐薬品性が高いポリプロピレンで成形されて、ガラス板１１をその周辺部で挟み込み、図３に示すようにねじ６６によりねじ固定している。蓋カバー９は透明なＡＢＳで成形されたものとしている。   As shown in FIG. 1, the drum-type washing machine 1 of the present embodiment shown in FIGS. 1 and 2 has a rotating drum 2 formed in a bottomed cylindrical shape from the opening front side to the back side as the bottom. The rotating shaft 20 is inclined in the downward direction from the horizontal direction so that the rotating shaft 20 is installed in the water tank 3 that is floatingly supported by the suspension, and the opening / closing lid 5 provided at the front part of the washing machine casing 4 is opened to open the laundry. Is stored in the rotating drum 2 and the rotating drum 2 is driven by the motor 6 so that at least one of a washing process, a rinsing process, and a dehydrating process can be performed. As shown in FIGS. 1 to 3, the opening / closing lid 5 is applied to a lid body 8 having a window 7 fitted with a transparent glass plate 11 through which the laundry is seen from the outside, and the front surface of the lid body 8. The lid cover 9 is made transparent so that the necessary fluoroscopic area leaving the front area or the periphery is left. The lid body 8 has a lid frame 8a molded from polypropylene, a back frame 8b molded from polypropylene having higher chemical resistance, and a glass plate 11 sandwiched between its peripheral portions, and a screw 66 as shown in FIG. It is fixed. The lid cover 9 is formed of transparent ABS.

ところで、本実施の形態のドラム式洗濯機１は、閉じた開閉蓋５は図１に示すように、回転ドラム２の開口端２ａと異なった角度で後部側に傾斜、従って後傾した関係とし、開閉蓋５が傾斜を持つことにより、洗濯物の出し入れ、洗濯、すすぎ、脱水に好適な十分な傾斜を持たせた回転ドラム２内の外部からの透視や、開閉蓋５設けた出し入れ口１２を通じた回転ドラム２に対する洗濯物の出し入れが特に不便にならないようにする。このために、水槽３の開口端３ａと閉じた開閉蓋５との間をシールする環状の蓋パッキング１３が、特許文献１に記載の環状の窓パッキングのように、側面視テーパ形で断面形状、各断面部のボリュームが周方向に不同になるのでは、水槽３の開口端３ａで特に大きくなる振動的な外力を受けた時の負荷がボリュームの大きな局部に増幅して集中し早期損傷、早期破損の原因になる。   By the way, in the drum type washing machine 1 of the present embodiment, the closed opening / closing lid 5 is inclined to the rear side at an angle different from the opening end 2a of the rotating drum 2 as shown in FIG. Since the opening / closing lid 5 has an inclination, it is possible to see from the outside in the rotary drum 2 having a sufficient inclination suitable for taking in / out laundry, washing, rinsing, and dewatering, and an opening / closing port 12 provided in the opening / closing lid 5. It is ensured that there is no particular inconvenience in and out of the laundry with respect to the rotating drum 2 through. Therefore, the annular lid packing 13 that seals between the open end 3a of the water tank 3 and the closed opening / closing lid 5 is tapered in a side view and has a sectional shape like the annular window packing described in Patent Document 1. If the volume of each cross-section becomes uneven in the circumferential direction, the load when receiving an external vibration force that becomes particularly large at the opening end 3a of the water tank 3 is amplified and concentrated in a local area with a large volume, resulting in early damage. Causes premature breakage.

これに対応すべく、開閉蓋５と水槽３の開口端３ａとの間を周方向に断面およびボリュームがほぼ均等で耐久性に優れた環状の窓パッキング１３によってシールできるようにするのに、開閉蓋５が、閉じ状態で、図１に示すように、回転ドラム２の回転軸２０に直角な開口端２ａと異なった角度で傾斜する関係において、水槽３の開口端３ａは、回転ドラム２の開口端２ａよりも前部側に突出して閉じた開閉蓋５とほぼ平行な傾斜にて対向し、これら開閉蓋５および水槽３の開口端３ａの間を前後端１３ａ、１３ｂ同士がほぼ平行な環状の窓パッキング１３にてシールするようにしている。これにより、開閉蓋５は洗濯物を回転ドラム２に収容した後に閉じることにより、回転ドラム２を回転させることで洗濯工程、すすぎ工程、脱水工程の少なくとも１つを行うのに、洗浄水、すすぎ水、脱水の飛沫などを外部に漏れ出るのを、水槽３の開口端３ａとの間をシールする環状の窓パッキング１３との間で阻止することができる。また、開閉蓋５と回転ドラム２の開口端２ａとは前記のような傾斜角度に違いによる特長を持ちながら、水槽３の開口端３ａは開閉蓋５と平行な傾斜を有してそれらの間を前後端１３ａ、１３ｂが平行な環状の窓パッキング１３によって前記シールができるようにするので、窓パッキング１３は断面形状および各断面部のボリュームが周方向に均等なものでよくなる。   To cope with this, the opening / closing lid 5 and the opening end 3a of the water tank 3 can be sealed with an annular window packing 13 having a substantially uniform cross section and volume in the circumferential direction and having excellent durability. With the lid 5 in the closed state, as shown in FIG. 1, the opening end 3 a of the water tank 3 is in contact with the rotating drum 2 in a relationship inclined at a different angle from the opening end 2 a perpendicular to the rotating shaft 20 of the rotating drum 2. The front and rear ends 13a, 13b are substantially parallel to each other between the opening / closing lid 5 and the opening end 3a of the water tank 3 so as to face the opening / closing lid 5 which projects to the front side of the opening end 2a and is closed. Sealing is performed with an annular window packing 13. Thus, the opening / closing lid 5 is closed after the laundry is accommodated in the rotating drum 2, and the rotating drum 2 is rotated to perform at least one of a washing process, a rinsing process, and a dehydrating process. It is possible to prevent leakage of water, dewatering splashes, and the like between the annular window packing 13 that seals between the opening end 3 a of the water tank 3. Further, while the opening / closing lid 5 and the opening end 2a of the rotating drum 2 have the above-described characteristics depending on the inclination angle, the opening end 3a of the water tank 3 has an inclination parallel to the opening / closing lid 5 and is between them. Are sealed by the annular window packing 13 with the front and rear ends 13a and 13b parallel to each other. Therefore, the window packing 13 may have a uniform cross-sectional shape and a volume of each cross-sectional portion in the circumferential direction.

以上の結果、回転ドラム２の開口端２ａと異なった角度で傾斜する開閉蓋５と、回転ドラム２を収容した水槽３の開口端３ａとの間をシールして、洗浄水、すすぎ水、脱水の飛沫などを外部に漏れ出るのを阻止する環状の窓パッキング１３が、開閉蓋５と水槽３の開口端３ａとをほぼ平行にしたことで、前後端１３ａ、１３ｂ同士がほぼ平行な形態にて前記シールができ、窓パッキング１３はその断面形状および各断面部のボリュームが周方向に均等なものとなるので、振れ動く水槽３の開口端３ａと停止している開閉蓋５との間で圧迫や変形力を周方向の変位を伴い繰り返し受けるときの負荷が周方向に均等化して局部に増幅して集中することはなく、早期に損傷したり破損したりせず長寿命化が実現する。   As a result, the gap between the opening / closing lid 5 that is inclined at a different angle from the opening end 2a of the rotating drum 2 and the opening end 3a of the water tank 3 housing the rotating drum 2 is sealed, so that washing water, rinsing water, dehydration The annular window packing 13 that prevents the splashes of the water from leaking outside makes the opening / closing lid 5 and the opening end 3a of the water tank 3 substantially parallel to each other so that the front and rear ends 13a and 13b are substantially parallel to each other. The window packing 13 has the same cross-sectional shape and volume in each cross-section in the circumferential direction, so that the opening end 3a of the swinging water tank 3 and the open / close lid 5 that is stopped The load when repeatedly receiving compression and deformation forces with circumferential displacement is equalized in the circumferential direction and does not concentrate and concentrate locally, resulting in long life without damage or breakage at an early stage. .

ここで、上記前後端１３ａ、１３ｂは、開閉蓋５との圧接端と水槽３の開口端３ａへの装着端を意味し、後端１３ｂは水槽３の開口端３ａ外周の環状凹部３ｂに弾性的に装着されて凹部３ｂ前面側の内向きフランジ３ｃの前面に着座する装着座部１３ｂ１をなし、前端１３ａは開閉蓋５の蓋本体８背面の内周側の連続した環状面５ａに圧着する圧着リップ１３ａ１および蓋本体８の窓７の内周に密嵌するシールリップ１３ａ２をほぼ直角断面の二股状に形成している。蓋パッキング１３全体としては前記装着座部１３ｂ１のフランジ３ｃの幅方向ほぼ中央位置とシールリップ１３ａ１、１３ａ２の二股状連結部との間を繋ぎ部１３ｃで繋いだ形態とするのに併せ、繋ぎ部１３ｃが、装着座部１３ｂ１の立ち上がり径に対し二股状連結部への繋がり径を小さくしたことを利用した、装着座部１３ｂ１から断面Ｍ字状をなして前部側へやや外方斜め向きになるよう一方の足部が立ち上がったＭ字部１３ｃ１と、このＭ字部１３ｃ１の非立ち上がり側他方の端部からの前部側に折り返して前記二股状連結部にシールリップ１３ａ２に開閉蓋５の軸線１４と平行に繋がる折り返し部１３ｃ２とを有したものとし、閉じた開閉蓋５と水槽３の開口端３ａにおけるフランジ３ｃとの間で蓋パッキング１３が必用なシール圧を自身の弾性により発揮して、しかも、Ｍ字部１３ｃ１が静止した開閉蓋５に圧接した前端１３ａ２側に対する水槽３の開口端３ａへ装着された後端１３ｂの水槽３の開口端３ａと共に振れ動くことに柔軟に対応する弾性緩衝部として働くようにしている。   Here, the front and rear ends 13 a and 13 b mean a pressure contact end with the opening / closing lid 5 and a mounting end to the opening end 3 a of the water tank 3, and the rear end 13 b is elastic to the annular recess 3 b on the outer periphery of the opening end 3 a of the water tank 3. The mounting seat portion 13b1 seated on the front surface of the inward flange 3c on the front surface side of the recess 3b is formed, and the front end 13a is crimped to the continuous annular surface 5a on the inner peripheral side of the back surface of the lid body 8 of the opening / closing lid 5. A sealing lip 13a2 that closely fits to the inner periphery of the window 7 of the lid lip 13a1 and the lid body 8 is formed in a bifurcated shape having a substantially right-angle cross section. The lid packing 13 as a whole is connected to the mounting seat 13b1 in the form in which the center portion in the width direction of the flange 3c and the bifurcated connecting portion of the seal lips 13a1 and 13a2 are connected by the connecting portion 13c. 13c uses the fact that the connecting diameter to the bifurcated connecting portion is reduced with respect to the rising diameter of the mounting seat portion 13b1, and forms an M-shaped cross section from the mounting seat portion 13b1 slightly obliquely outward toward the front side. The M-shaped portion 13c1 with one leg raised so as to be folded back to the front side from the other end of the M-shaped portion 13c1 on the non-rise side, and the sealing lip 13a2 is connected to the bifurcated connecting portion of the opening / closing lid 5 A sealing pressure required for the lid packing 13 between the closed opening / closing lid 5 and the flange 3c at the opening end 3a of the water tub 3 is assumed to have a folded portion 13c2 connected in parallel with the axis 14. The M-shaped portion 13c1 swings with the opening end 3a of the aquarium 3 at the rear end 13b attached to the opening end 3a of the aquarium 3 with respect to the front end 13a2 side pressed against the stationary opening / closing lid 5. In particular, it is designed to work as an elastic buffer that can be flexibly adapted.

ところで、開閉蓋５は、図１に示すように、回転ドラム２の開口端２ａと、垂直面との間の角度で傾斜していることになるが、洗濯機筐体４は、前面４ａがほぼ垂直に形成されたものとしている。これにより、開閉蓋５が、回転ドラム２の開口端２ａと垂直面との間の角度で傾斜していることが、開閉蓋５の回転ドラム２の開口端２ａとの角度差を抑えられるのに併せ、洗濯機筐体４のほぼ垂直な前面４ａとの角度差をも抑えて、垂直な洗濯機筐体前面４ａに対する飛び出しまたはおよび窪みの量を抑えられる。これは、洗濯機筐体４を前面同士が揃うようにビルトインした図１に仮想線で一部を示すような各種の家具１４をも含む垂直な前面に対する傾斜による飛び出しまたはおよび窪みの量を抑えられるので、家具および機器双方の体裁がよくなる。   As shown in FIG. 1, the opening / closing lid 5 is inclined at an angle between the opening end 2a of the rotating drum 2 and the vertical surface. It is assumed that they are formed almost vertically. Thereby, the angle difference between the opening end 2a of the opening / closing lid 5 and the opening end 2a of the rotating drum 2 can be suppressed because the opening / closing lid 5 is inclined at an angle between the opening end 2a of the rotating drum 2 and the vertical plane. In addition, the angle difference from the substantially vertical front surface 4a of the washing machine casing 4 can be suppressed, and the amount of protrusion or depression to the vertical washing machine casing front surface 4a can be suppressed. This is because the washing machine housing 4 is built-in so that the fronts are aligned with each other, and the amount of protrusions and depressions due to the inclination with respect to the vertical front surface including various furniture 14 as shown in phantom lines in FIG. 1 is suppressed. Therefore, the appearance of both furniture and equipment is improved.

また、図示する例では、水槽３は、その胴部３１の前部側に回転ドラム２の開口端２ａとほぼ平行に内径側に向く肩部３２を有し、この肩部３２から閉じた開閉蓋５とほぼ平行な位置まで周方向に異なる高さとした立ち上がり壁３３を有して開口端３ａを形成し、この立ち上がり壁３３の立ち上がり端部に窓パッキング１３の後端部１３ｂを装着している。これにより、水槽３が胴部３１前部側で回転ドラム２の開口端２ａとほぼ平行に内径側に向く肩部３２を設けて回転ドラム２の胴部２１側の必要前部域を覆って回転する回転ドラム２に対する外部からの安全を図りながら、水槽３の開口端３ａを肩部３２からの周方向に高さが異なった立ち上がり壁３３により開閉蓋５とほぼ平行にして前後端１３ａ、１３ｂが平行な窓パッキング１３を開閉蓋５とのシールのために必要なバックアップ位置を、前記Ｍ字部１３ｃを有した形態などにて満足し支持することができ、必要最小限のボリュームとした窓パッキング１３にて十分なシールを確保することができる。   In the illustrated example, the water tank 3 has a shoulder portion 32 facing the inner diameter side substantially parallel to the opening end 2 a of the rotating drum 2 on the front side of the trunk portion 31, and is opened and closed closed from the shoulder portion 32. An opening end 3 a is formed having a rising wall 33 with different heights in the circumferential direction to a position substantially parallel to the lid 5, and a rear end portion 13 b of the window packing 13 is attached to the rising end portion of the rising wall 33. Yes. As a result, the water tank 3 is provided with a shoulder portion 32 facing the inner diameter side substantially parallel to the opening end 2a of the rotating drum 2 on the front side of the body portion 31 to cover the necessary front region on the body portion 21 side of the rotating drum 2. Front and rear ends 13a, with the opening end 3a of the water tank 3 being substantially parallel to the opening / closing lid 5 by the rising wall 33 having a different height in the circumferential direction from the shoulder portion 32, while ensuring safety from the outside with respect to the rotating drum 2 that rotates. The back-up position required for sealing the window packing 13 parallel to 13b with the opening / closing lid 5 can be satisfactorily supported by the form having the M-shaped portion 13c, etc., and the minimum volume is required. A sufficient seal can be secured by the window packing 13.

さらに、肩部３２と立ち上がり壁３３とがなす周方向段差部３４に、その段差範囲内にほぼ収まる嵩の錘１５を図１、図５に示すようにねじ１６により肩部３２上の図１、図７に示す複数のボス部３２ａにねじ止めするなどして取り付けてある。このような錘１５は、水槽３の振動を受けてその振動エネルギを分散して減衰するために用いられるが、水槽３の最も動きの大きい前端部３ａとなる、肩部３２と立ち上がり壁３３とがなす周方向段差部３４に設けたことで、振動の抑制効率を高められる。また、錘１５が段差部３４内にほぼ収まる嵩であることにより、錘１５が水槽３と共に窓パッキング１３を変形させながら振動的に移動するときの窓パッキング１３との相対移動によっても、窓パッキング１３と干渉するのを回避することができ、窓パッキング１３を損傷させるようなことがない。特に、段差部３４の段差が大きくなる上部などではそこに設ける錘１５の嵩を段差に見合って大きくして問題がなく周方向の単位長さに対する重量を高めて、振動の抑制効果を高められる。この錘１５を設けた水槽３の肩部３２の内側を通じ水槽３の外部から錘１５を取り付ける肩部３２のボス部３２ａを避けて配管された図１、図７に示す注水管３０を通じて、図１に示す覆い部材１７の注水口４０を介し回転ドラム２内に仮想線で示すように噴射し洗濯物、特に衣類に効果的に注水できるようにしている。   Furthermore, a weight 15 having a bulk which is substantially within the step range is provided on the circumferential step 34 formed by the shoulder 32 and the rising wall 33, as shown in FIGS. These are attached to the plurality of boss portions 32a shown in FIG. Such a weight 15 is used for receiving vibration of the water tank 3 and dispersing and attenuating the vibration energy, but the shoulder part 32 and the rising wall 33 which become the front end part 3a with the largest movement of the water tank 3 As a result, the vibration suppression efficiency can be increased. Further, since the weight 15 has a bulk that can be substantially accommodated in the stepped portion 34, the window packing is also caused by relative movement with the window packing 13 when the weight 15 is moved with the water tank 3 while deforming the window packing 13. Interference with 13 can be avoided, and the window packing 13 is not damaged. In particular, in the upper part where the level difference of the level difference part 34 is large, the weight of the weight 15 provided there is increased corresponding to the level difference to increase the weight with respect to the unit length in the circumferential direction without any problem, and the vibration suppressing effect can be enhanced. . Through the water injection pipe 30 shown in FIGS. 1 and 7, which is piped to avoid the boss portion 32 a of the shoulder portion 32 to which the weight 15 is attached from the outside of the water tank 3 through the inside of the shoulder portion 32 of the water tank 3 provided with the weight 15. 1 is sprayed into the rotary drum 2 through the water injection port 40 of the cover member 17 shown in FIG. 1 so as to effectively inject water into the laundry, particularly clothes.

また、水槽３の開口端３ａと回転ドラム２の開口端２ａとの隙間は、それらの傾斜角度差に見合った側面視幅を有する環状覆い部材１７で覆うようにしている。これにより、水槽３の開口端３ａと回転ドラム２の開口端２ａとの隙間Ｓを覆う環状の覆い部材１７が、水槽３および回転ドラム２の開口端２ａ、３ａ間の角度差に見合った側面視幅を有して、側面視テーパ形となっていることにより、水槽３および回転ドラム２の開口端２ａ、３ａ間が前記角度差によって側面視テーパ形をなした隙間を過不足なく塞いで覆うことができ、覆い部材１７の材料に無駄なく洗濯物が水槽３および回転ドラム２の開口端２ａ、３ａ間に挟み込まれるのを防止することができる。   Further, the gap between the opening end 3a of the water tank 3 and the opening end 2a of the rotating drum 2 is covered with an annular covering member 17 having a side view width corresponding to the difference in inclination angle. Thereby, the annular covering member 17 covering the gap S between the opening end 3a of the water tank 3 and the opening end 2a of the rotating drum 2 is a side face corresponding to the angular difference between the opening ends 2a and 3a of the water tank 3 and the rotating drum 2. By having a viewing width and a side view taper shape, the gap between the water tank 3 and the open ends 2a and 3a of the rotary drum 2 formed in a side view taper shape by the angle difference is completely closed. The covering material 17 can be covered, and the laundry can be prevented from being caught between the water tank 3 and the open ends 2a and 3a of the rotating drum 2 without waste.

なお、回転ドラム２のその胴部２１の前部に内径側に向く肩部２２を有して胴部２１よりも小径の開口端を形成することで、洗濯やすすぎに必要な水深を確保できるようにしているのに対し、水槽３の肩部３２は、立ち上がり壁３３の立ち上がり端から内径側に延びる前記フランジ３ｃの内週に、回転ドラム２の開口端２ａと一定の隙間を保って対向する内周壁３５を有した一部で二重周壁を構成する開口端３ａとしている。これにより、開口端２ａ、３ａ間の隙間幅が周方向で違って、場所によって大きな隙間幅となるのを回避している。また、覆い部材１７の前端は、水槽３の開口端３ａの内周近くで開口端３ａよりも前部側に若干突出して、水槽３の開口端３ａの内周を回転ドラム２の開口端２ａ近くまでを覆い、かつ、その覆い部の内径が回転ドラム２の開口端２ａの内径よりも小さくなるようにしてある。覆い部材１７は水槽３の肩部３２の内側面に形成したボス部３２ａにねじ１８によってねじ止めしてある。   In addition, it has the shoulder part 22 which faces the internal diameter side in the front part of the trunk | drum 21 of the rotating drum 2, and forms the opening end of a smaller diameter than the trunk | drum 21, The water depth required for washing and rinsing can be ensured. On the other hand, the shoulder 32 of the water tank 3 is opposed to the opening end 2a of the rotating drum 2 with a certain gap in the inner week of the flange 3c extending from the rising end of the rising wall 33 toward the inner diameter side. A part having the inner peripheral wall 35 is an open end 3a constituting a double peripheral wall. Thereby, it is avoided that the gap width between the open ends 2a and 3a differs in the circumferential direction and becomes a large gap width depending on the place. Further, the front end of the covering member 17 slightly protrudes toward the front side of the opening end 3 a near the inner periphery of the opening end 3 a of the water tank 3, and the inner periphery of the opening end 3 a of the water tank 3 extends to the opening end 2 a of the rotating drum 2. The inner diameter of the covering portion is made smaller than the inner diameter of the opening end 2a of the rotary drum 2. The cover member 17 is screwed to a boss portion 32 a formed on the inner surface of the shoulder portion 32 of the water tank 3 with a screw 18.

一方、前記開閉蓋５は、前記洗濯機筐体４の前面４ａを形成するボディーパネル４１から後部側に傾斜して、この前面４ａから凹陥した環状域である凹陥部４２の後部側に傾斜した底部に開口する出し入れ口１２を閉じる関係にある。このように、開閉蓋５および出し入れ口１２が洗濯機筐体４の前面４ａに対し後傾して位置するので、洗濯機筐体４の前面４ａの角度如何にかかわらず、回転ドラム２の傾斜姿勢と併せ、洗濯物の出し入れ、外部からの洗濯物の透視に便利であり、洗濯機筐体４の前面４ａの角度は水平方向に対する垂直、水平に対する開閉蓋、出入り口１２の後傾角未満までの後傾を含め自由に選択することができる。この結果、開閉蓋５および出し入れ口１２が洗濯機筐体４の前面４ａに対し後傾していて、洗濯機筐体４の前面４ａの角度にかかわらず、回転ドラム２の傾斜姿勢と併せ、洗濯物の出し入れ、外部からの洗濯物の透視に便利で使用しやすいものとなるし、洗濯機筐体４の前面４ａの角度は垂直、後傾を含めた選択の自由度が高まるので、各種用途や要求に対応しやすい。   On the other hand, the opening / closing lid 5 is inclined to the rear side from the body panel 41 forming the front surface 4a of the washing machine casing 4, and is inclined to the rear side of the recessed portion 42 which is an annular region recessed from the front surface 4a. It is in the relationship which closes the entrance / exit 12 opened to a bottom part. As described above, since the opening / closing lid 5 and the entrance / exit 12 are tilted backward with respect to the front surface 4a of the washing machine casing 4, the inclination of the rotary drum 2 is independent of the angle of the front surface 4a of the washing machine casing 4. Together with the posture, it is convenient for taking in and out the laundry and seeing the laundry from the outside. The angle of the front surface 4a of the washing machine casing 4 is vertical to the horizontal direction, the opening / closing lid with respect to the horizontal, and the rear tilt angle of the entrance 12 You can choose freely including backward tilt. As a result, the opening / closing lid 5 and the entrance / exit 12 are tilted rearward with respect to the front surface 4a of the washing machine casing 4, and the tilted attitude of the rotary drum 2 regardless of the angle of the front surface 4a of the washing machine casing 4, It is convenient and easy to use for taking in and out the laundry and seeing the laundry from the outside, and the angle of the front surface 4a of the washing machine housing 4 is increased in the degree of freedom of selection including vertical and backward tilt. Easy to meet applications and requirements.

しかし、垂直な前面４ａに対し開閉蓋５を内側に後傾させて設けるのに、開閉蓋５が出し入れ口１２を閉じる閉じ域およびそのまわりの図１、図６に示すような凹陥部４２が、その下部から上部に向けて、図１に示すようにボディーパネル４１がなす前面４ａから深く入り込んだ深絞り形状部になり、洗濯機筐体４および開閉蓋５などの付帯物支持に必要な強度を満足する厚さを持ったボディーパネル４１の成形が難しくコスト高になる。これに対応するのに、ボディーパネル４１は、凹陥部４２の前面４ａへの開口側を有した枠状のボディーパネル４１ａと、前記凹陥部４２の出し入れ口１２を有した底部側をなす環状のボディーパネル４１ｂとを一体化して形成し、前記凹陥部４２は、環状のカバーパネル４４で覆って外装している。これにより、ボディーパネル４１が形成する前面４ａから凹陥し、この前面４ａに対し後部側に傾斜した底部に出し入れ口１２を開口している凹陥部４２は、前面４ａからの深絞り形状部となっても、その開口側と底部側とが前記枠状のボディーパネル４１ａと環状のボディーパネル４１ｂとに分担して形成し一体化して得られるので、深絞り加工を回避して容易かつ低コストで実現する。しかも、凹陥部４２は前記両ボディーパネル４１ａ、４１ｂの一体化構造部を有しても、カバーパネルで覆うだけで外装し外観が整えられる。   However, in order to provide the opening / closing lid 5 so as to be tilted rearward with respect to the vertical front surface 4a, a closed region where the opening / closing lid 5 closes the entrance / exit 12 and a concave portion 42 as shown in FIGS. From the lower part to the upper part, as shown in FIG. 1, it becomes a deep drawing shape part that penetrates deeply from the front surface 4a formed by the body panel 41, and is necessary for supporting accessories such as the washing machine casing 4 and the opening / closing lid 5 Forming the body panel 41 having a thickness that satisfies the strength is difficult and costly. Corresponding to this, the body panel 41 has a ring-shaped body panel 41a having an opening side to the front surface 4a of the recessed portion 42 and an annular portion forming the bottom portion side having the access port 12 of the recessed portion 42. The body panel 41b is integrally formed, and the recessed portion 42 is covered and covered with an annular cover panel 44. Accordingly, the recessed portion 42 that is recessed from the front surface 4a formed by the body panel 41 and opens the inlet / outlet port 12 at the bottom inclined to the rear side with respect to the front surface 4a becomes a deep drawing shape portion from the front surface 4a. However, since the opening side and the bottom side of the frame-like body panel 41a and the annular body panel 41b are formed and integrated, it is easy and low cost by avoiding deep drawing. Realize. Moreover, even if the recessed portion 42 has an integrated structure portion of both the body panels 41a and 41b, it can be covered and trimmed by simply covering it with the cover panel.

さらに具体的には、出し入れ口１２は、図１、図２に示すような洗濯機筐体４の前面４ａの上下部分を除く範囲を形成する金属製のボディーパネル４１に形成し、環状のボディーパネル４１ｂとその周辺の枠状のボディーパネル４１ａとの一体化は各種溶接、かしめ、鋲止め、ねじ止めなど、どのようにもできるが、図示例では図６に示すようにスポット溶接部４３にて一体化している。この一体化のために、環状のボディーパネル４１ｂは、内周に前記蓋パッキング１５と圧接するように後部側に向く環状膨らみ部４１ｂ１を前部側に溝をなして形成し、この環状膨らみ部から周辺に平坦に延びた後上部側で大きな曲面をなし下部側で屈曲して立ち上がる外周壁４１ｂ２を持って凹陥部４２の底部側をなし、この外周壁４１ｂ２の前端に外向きのフランジ部４１ｂ３を形成したものとし、枠状のボディーパネル４１ａは洗濯機筐体４の前面４ａ形成域に環状域４２の外周部に対応する凹陥周壁４１ａ１を形成して凹陥部４２の開口側をなし、この凹陥周壁４１ａ１の後端縁に前記フランジ部４１ｂ３に後方から当てがう内向きのフランジ部４１ａ２を形成したものとし、これらフランジ部４１ａ３、４１ａ２の重なり部を前記スポット溶接部４３が示す周方向複数個所でのスポット溶接に供するようにしている。   More specifically, the access port 12 is formed in a metal body panel 41 that forms a range excluding the upper and lower portions of the front surface 4a of the washing machine housing 4 as shown in FIGS. The panel 41b and the surrounding frame-shaped body panel 41a can be integrated by various methods such as welding, caulking, tacking, and screwing. In the illustrated example, as shown in FIG. Are integrated. For this integration, the annular body panel 41b is formed with an annular bulging portion 41b1 facing the rear side so as to be in pressure contact with the lid packing 15 on the inner periphery with a groove formed on the front side, and this annular bulging portion. The outer peripheral wall 41b2 which has a large curved surface at the upper part after extending flat from the periphery to the periphery and bends at the lower part and rises to form the bottom side of the recessed part 42, and has an outward flange part 41b3 at the front end of the outer peripheral wall 41b2. The frame-shaped body panel 41a forms a concave peripheral wall 41a1 corresponding to the outer peripheral portion of the annular region 42 in the front surface 4a formation region of the washing machine housing 4 to form the opening side of the concave portion 42. It is assumed that an inward flange portion 41a2 applied to the flange portion 41b3 from the rear is formed at the rear edge of the recessed peripheral wall 41a1, and an overlapping portion of the flange portions 41a3 and 41a2 is formed as described above. Pot welds 43 are so subjected to spot welding in the circumferential direction a plurality of locations indicated.

ここで、環状なボディーパネル４１ｂの左右一方の側に図６に示すヒンジユニット５１を前部側から当てがいねじ５２によりねじ止めして取り付け、このヒンジユニット５１によって開閉蓋５を開閉できるように支持し、他方の側に図３に示す開閉蓋５の係合片５ａをロック窓５３ａに受入れてロックし開閉蓋５を閉じ状態に係止する、蓋閉じ検知スイッチ付きの蓋ロック部５３、およびこれのロックを解除する蓋開きボタン５６を前部側から当てがいねじ５５、５７によってそれぞれねじ止めし装備している。これらヒンジユニット５１は特開２００５−１４３７９４号公報などで、蓋ロック部５３および蓋開きボタン５４は特開２００５−１３７５０８号公報などでそれぞれ知られたものでよく、ここでは特に詳述しない。   Here, the hinge unit 51 shown in FIG. 6 is attached to the left and right sides of the annular body panel 41b by a fastening screw 52 from the front side so that the opening / closing lid 5 can be opened and closed by the hinge unit 51. 3, a lid lock portion 53 with a lid closing detection switch that receives and locks the engagement piece 5a of the opening / closing lid 5 shown in FIG. 3 in the lock window 53a and locks the opening / closing lid 5 in the closed state. Also, a lid opening button 56 for releasing the lock is equipped by screwing from the front side with application screws 55 and 57, respectively. The hinge unit 51 may be known from Japanese Patent Laid-Open No. 2005-143794, and the lid lock portion 53 and the lid opening button 54 may be known from Japanese Patent Laid-Open No. 2005-137508.

さらに、枠状のボディーパネル４１ａは、図６に示すように、洗濯機筐体４の前面４ａを形成する矩形部は周壁４１ａ３を有した浅いボックス型で、このボックス型の上部に環状の凹陥周壁４１ａ２が前記環状域４２の幅寸法程度で丸く張り出した形状をなし、環状のボディーパネル４１ｂは厚く、枠状のボディーパネル４１ａは薄くした板厚の組み合わせで、それらボディーパネル４１ａ、４１ｂの前記重ねスポット溶接構造および立体形状が合わさって必要強度を満足し、面積の大きなボディーパネル４１ａの板厚を薄くできた分だけ洗濯機筐体４が軽量化し低コスト化する。   Further, as shown in FIG. 6, the frame-shaped body panel 41a is a shallow box type in which the rectangular part forming the front surface 4a of the washing machine casing 4 has a peripheral wall 41a3, and an annular recess is formed in the upper part of the box type. The peripheral wall 41a2 has a shape that is rounded to the extent of the width of the annular region 42, the annular body panel 41b is thick, and the frame-like body panel 41a is a combination of thin plate thicknesses. The overlap spot welding structure and the three-dimensional shape are combined to satisfy the required strength, and the washing machine housing 4 is reduced in weight and cost by the amount that the body panel 41a having a large area can be thinned.

また、ボディーパネル４１の前記ヒンジユニット５１、蓋ロック部５３および蓋開きボタン５４を装備する環状域４２は、図３に示すように蓋開きボタン５４を除き、樹脂製の環状なカバーパネル４４で覆って外装し、カバーパネル４４を図１、図３に示すようにねじ４５により環状のボディーパネル４１ｂに周方向複数個所でねじ止めしている。これにより、カバーパネル４４を前部側に外すと、ボディーパネル４１に装備したヒンジユニット５１、蓋ロック部５３および蓋開きボタン５４が露出させられるので、それらの補修や交換のメンテナンスができる。   Further, the annular region 42 equipped with the hinge unit 51, the lid lock portion 53 and the lid opening button 54 of the body panel 41 is a resin-made annular cover panel 44 except for the lid opening button 54 as shown in FIG. As shown in FIGS. 1 and 3, the cover panel 44 is screwed to the annular body panel 41b at a plurality of locations in the circumferential direction by screws 45 as shown in FIGS. As a result, when the cover panel 44 is removed to the front side, the hinge unit 51, the lid lock portion 53, and the lid opening button 54 provided on the body panel 41 are exposed, so that repair and replacement maintenance thereof can be performed.

さらに、洗濯機筐体４の前面４ａは、ボディーパネル４１ａと、その上部および天板５７間を塞ぐ樹脂製のトップマークユニット５８と、ボディーパネル４１ａの下部を着脱できるように塞ぐ樹脂製の開閉パネル５９とで形成し、トップマークユニット５８は、スタート、停止のスイッチキー６１や各種モードの設定操作部６２、液晶表示部６３、表示ランプなどを配置した操作面としている。ここに、カバーパネル４４およびトップマークユニット５８は共に樹脂成形品であって、互いが上下に隣接し合う対向面４４ａ、５８ａは共に表面に直角をなして続くように成形でき、それらを図１、図２に示すように隙間なく突き合わせられる。これによって、洗濯機筐体４の前面４ａの上部を形成する横長な樹脂面に、これに上部が食い込んだ形で中央側に向け後部側に傾斜した樹脂面が隙間なく異なった色で連続した特異な外観としながら、このように連続したカバーパネル４４およびトップマークユニット５８の、材質の違う金属製のボディーパネル４１ａとの対向面４４ｂ、５８ｂが、開閉パネル５９の対向面５９ａと共に、ボディーパネル４１ａの側周壁４１ａ３や凹陥周壁４１ａ１と隣接し合うのに、それら側周壁４１ａ３や凹陥周壁４１ａ１を曲げ加工したことによる丸みを持ったコーナ部が隙間をなす突き合わせ部をなして、それらの表面の存在、独立性を強調する外観構成を実現している。   Further, the front surface 4a of the washing machine casing 4 is formed of a resin panel that covers the body panel 41a, a resin top mark unit 58 that covers the upper portion of the body panel 41a and the top plate 57, and a lower portion of the body panel 41a. The top mark unit 58 is formed of a panel 59, and has an operation surface on which a start / stop switch key 61, a setting operation unit 62 for various modes, a liquid crystal display unit 63, a display lamp, and the like are arranged. Here, the cover panel 44 and the top mark unit 58 are both resin molded products, and the opposing surfaces 44a and 58a that are adjacent to each other in the vertical direction can be formed so as to continue at a right angle to the surface. As shown in FIG. As a result, the resin surface inclined to the rear side toward the center side in a shape where the upper portion bites into the horizontally long resin surface forming the upper portion of the front surface 4a of the washing machine casing 4 is continuous with different colors without any gaps. The surface 44b, 58b of the continuous cover panel 44 and the top mark unit 58 facing the metal body panel 41a made of different materials, together with the facing surface 59a of the opening / closing panel 59, has a body panel. 41a3 is adjacent to the side peripheral wall 41a3 and the concave peripheral wall 41a1, but the rounded corners by bending the side peripheral wall 41a3 and the concave peripheral wall 41a1 form a butt portion that forms a gap, Appearance composition that emphasizes existence and independence is realized.

カバーパネル４４およびトップマークユニット５８の突き合わせは、トップマークユニット５８がボディーパネル４１ａの凹陥周壁４１ａ２の前端に被さって実現している。また、この被さり構造は、ボディーパネル４１ａの上部にトップマークユニット５８を前部側から嵌め付けて装着し、ボディーパネル４１ａの側周壁４１ａ３の前端に被さるようにして実現している。従って、ボディーパネル４１ａの取り外しは、トップマークユニット５８の取り外しを優先して行わないとできない。これに対応してトップマークユニット５８は、ボディーパネル４１ａの側周壁４１ａ３とその外側に設けた洗濯機筐体４側の固定壁６４間に上下壁５８ａ、５８ａを前部から嵌め込み、それら上下壁５８ａ、５８ａに外向きに形成した逆止突起５８ｃを、上下壁５８ａ、５８ｂの弾性を利用して、側周壁４１ａ３および固定壁６４に形成した係止孔６５に弾性係合させることで抜け止し、この抜けどめ力に打ち勝つ取り外し力にてボディーパネル４１ａを簡単に取り外せるようにしている。   The butting of the cover panel 44 and the top mark unit 58 is realized by the top mark unit 58 covering the front end of the recessed peripheral wall 41a2 of the body panel 41a. In addition, this covering structure is realized by attaching the top mark unit 58 to the upper portion of the body panel 41a from the front side and covering the front end of the side peripheral wall 41a3 of the body panel 41a. Therefore, the body panel 41a cannot be removed unless the top mark unit 58 is prioritized. Correspondingly, the top mark unit 58 is fitted with upper and lower walls 58a, 58a from the front part between the side peripheral wall 41a3 of the body panel 41a and the fixed wall 64 on the washing machine housing 4 side provided on the outer side thereof. A check protrusion 58c formed outwardly on 58a and 58a is elastically engaged with a locking hole 65 formed in the side peripheral wall 41a3 and the fixed wall 64 by utilizing the elasticity of the upper and lower walls 58a and 58b, thereby preventing the protrusions 58c. In addition, the body panel 41a can be easily removed by the detaching force that overcomes the pull-out force.

最後に、前記トップマークユニット５８は、図１に示すようにその前面５８ａが後部側に若干傾斜して設けたている。これにより、トップマークユニット５８の前面５８ａが後部側に若干傾斜しているので、ビルトイン対象家具１４の垂直な前面１４ａから、あまり窪むことなくユーザーの自然な視線に対する傾きを抑えられる。この結果、トップマークユニット５８の前面５８ａがビルトイン対象家具１４の垂直な前面１４ａから、あまり窪むことなく、従って、対象家具１４との前面１４ａの揃い度を余り崩さずに、ユーザーの自然な視線に対する傾きを抑えて視認しやすく操作しやすいものとすることができる。   Finally, as shown in FIG. 1, the top mark unit 58 has a front surface 58a slightly inclined toward the rear side. Thereby, since the front surface 58a of the top mark unit 58 is slightly inclined to the rear side, the inclination with respect to the user's natural line of sight can be suppressed without being depressed so much from the vertical front surface 14a of the built-in target furniture 14. As a result, the front surface 58a of the top mark unit 58 does not sink so much from the vertical front surface 14a of the built-in target furniture 14, and thus the naturalness of the user can be reduced without significantly changing the degree of alignment of the front surface 14a with the target furniture 14. The tilt with respect to the line of sight can be suppressed, and it can be easily viewed and operated.

回転ドラムを傾斜して設置したドラム式洗濯機で、洗濯機筐体の前面に対し開閉蓋および出し入れ口が後傾した使用に便利なものとしながら、洗濯機筐体の前面は垂直を含む開閉蓋および出入り口未満の後傾角度未満の自由な範囲で対応できる。   A drum-type washing machine with a rotating drum installed at an angle, and the front and back of the washing machine housing includes a vertical opening and closing, while the opening and closing lid and the entrance / exit are inclined backwards with respect to the front of the washing machine housing. It is possible to cope with a free range less than the back tilt angle less than the lid and the doorway.
