図３において、ドラム式洗濯機の本体１内に、水槽２が宙吊り状態に配設され、前記水槽２内に有底円筒形に形成された回転ドラム３がその軸心方向を正面側から背面側に向けて下向きに傾斜させてかつ回転自在に配設されている。前記水槽２の正面側には回転ドラム３の開口端に通じる衣類出入口４が形成され、本体１の前面を構成する前部枠体５の前部に形成された上向き傾斜面に設けられた開口部６を開閉する扉９を開くことにより、衣類出入口４を通じて回転ドラム３内の洗濯物を出し入れすることができる。扉９が上向き傾斜面に設けられているため、洗濯物を出し入れする作業を腰を屈めることなく実施でき、一般には横向きにある開口部から洗濯物を出し入れするドラム式洗濯機の作業性の悪さが改善されている。 In FIG. 3, a water tub 2 is suspended in a main body 1 of a drum-type washing machine, and a rotating drum 3 formed in a bottomed cylindrical shape in the water tub 2 has its axial direction from the front to the back. It is tilted downward toward the side and is rotatably arranged. On the front side of the water tank 2 is formed a clothing doorway 4 leading to the opening end of the rotating drum 3, and an opening provided on an upward inclined surface formed at the front portion of the front frame body 5 constituting the front surface of the main body 1. By opening the door 9 that opens and closes the part 6, the laundry in the rotary drum 3 can be taken in and out through the clothing entrance 4. Since the door 9 is provided on the upward inclined surface, the work for putting in and out the laundry can be carried out without bending the waist, and generally the workability of the drum type washing machine for taking in and out the laundry from the sideways opening is provided. The evil has been improved.
回転ドラム３の周面に水槽２内に通じる多数の透孔１０が形成され、水槽２の背面側に取り付けられたモータ１１によって正転及び逆転方向に回転駆動される。前記水槽２には、注水管路１２及び排水管路１３が配管接続され、注水弁１４および排水弁１５の制御によって水槽２内への注水及び排水がなされる。 A large number of through holes 10 communicating with the water tank 2 are formed on the peripheral surface of the rotating drum 3, and are driven to rotate in the forward and reverse directions by a motor 11 attached to the back side of the water tank 2. A water injection pipe 12 and a drain pipe 13 are connected to the water tank 2, and water injection and drainage into the water tank 2 are performed by controlling the water injection valve 14 and the drain valve 15.
前部枠体５の上部には操作表示パネル１６が配置され、その左下には洗剤投入ケース１７（図４に記載）が前方に引き出し自在に前部枠体５に配置されている。使用者は運転に先立ち洗剤を洗剤投入ケース１７に入れ、必要に応じて操作表示部１６を操作することにより、希望する運転内容を設定したり、運転スタート、一時停止を行い、運転の進行状態を認識することができる。 An operation display panel 16 is disposed on the upper part of the front frame body 5, and a detergent charging case 17 (described in FIG. 4) is disposed on the front frame body 5 so that it can be pulled out forward. Prior to driving, the user puts the detergent into the detergent charging case 17 and operates the operation display unit 16 as necessary to set the desired driving content, start driving, pause, and the driving progress state. Can be recognized.
扉９を開いて回転ドラム３内に洗濯物を投入して運転を開始させると、注水弁１４が開き、洗剤投入ケース１７内に水が注水され、その中に投入されていた洗剤を流しながら、注水管路１２を介して水槽２内に所定量の注水がなされ、モータ１１により回転ドラム３が回転駆動されて洗濯行程が開始される。洗濯行程の洗濯物は、回転ドラム２の回転により回転方向に持ち上げられ落下する撹拌動作が繰り返され洗濯がなされる。 When the door 9 is opened and the laundry is put into the rotating drum 3 to start operation, the water injection valve 14 is opened, water is poured into the detergent charging case 17, and the detergent that has been poured therein is being poured. A predetermined amount of water is injected into the water tank 2 through the water injection pipe 12, and the rotating drum 3 is driven to rotate by the motor 11 to start the washing process. The laundry in the washing process is washed by repeating the stirring operation that is lifted in the rotating direction by the rotation of the rotating drum 2 and dropped.
所要の洗濯時間の後、排水弁１５が開き、汚れた洗濯液は排水管路１３から排出され、回転ドラム３を高速回転させる脱水動作により洗濯物に含まれた洗濯液を脱水し、その後、水槽２内に注水管路１２から注水され、すすぎ行程が実施される。このすすぎ行程においても、洗濯物には回転ドラム２の回転により撹拌動作が繰り返されてすすぎ洗いが実施される。 After the required washing time, the drain valve 15 is opened, the dirty washing liquid is discharged from the drain pipe 13, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation of rotating the rotating drum 3 at a high speed. Water is poured into the water tank 2 from the water injection pipe 12 and a rinsing process is performed. Also in the rinsing process, the laundry is rinsed by repeating the stirring operation by the rotation of the rotating drum 2.
図５、図６、図７、図８において、操作表示パネル１６は、前部枠体５の上方と天板１８との間に配置され、透明樹脂部１９の表面がインサート成形されたフィルム２０（ＰＥＴフィルム）で覆われて着色、印刷が施された化粧面を成し、中央に略矩形形状を成す開口窓２１が設けられる。この開口窓２１は透明樹脂もフィルムも無い領域であり、その裏面には透明ガラス板２２が弾性体２３を介して操作表示パネル１６に取付けられ、この透明ガラス板２２の裏面には透明電極２４が接着される。また前記透明ガラス板２２の裏面側には液晶パネル２５が液晶取付台２６に取付けられ、この液晶取付台２６の裏面には前記透明電極や前記液晶パネルを制御する制御基板ユニットＡ２７が取付けられる。 5, 6, 7, and 8, the operation display panel 16 is disposed between the top of the front frame 5 and the top plate 18, and a film 20 in which the surface of the transparent resin portion 19 is insert-molded. An opening window 21 having a decorative surface covered with (PET film) and colored and printed and having a substantially rectangular shape is provided at the center. The opening window 21 is an area having neither transparent resin nor film, and a transparent glass plate 22 is attached to the operation display panel 16 via an elastic body 23 on the back surface thereof, and a transparent electrode 24 is mounted on the back surface of the transparent glass plate 22. Is glued. A liquid crystal panel 25 is attached to a liquid crystal mounting base 26 on the back side of the transparent glass plate 22, and a control board unit A 27 for controlling the transparent electrode and the liquid crystal panel is attached to the back side of the liquid crystal mounting base 26.
前記操作表示パネル１６は押圧操作ボタン部２８や発光表示部２９も有し、この操作表示パネル１６の内部にはスイッチ３０や発光素子３１などを積載した制御基板ユニットＢ３２があり、裏面カバー３３に取付けられる。また前記発光素子３１の光を前記発光表示部２９に導く導光経路３４や、スイッチ３０を押圧操作するボタン部３５を有する操作部材３６が、前記操作表示パネル１６と前記裏面カバー３３の間に設けられる。前記押圧操作ボタン部２８には透明樹脂部１９が無くフィルム２０のみが存在するので、軽い操作力でスイッチ３０を操作できる。また発光表示部２９には透過性の高い印刷が施され発光素子３１の弱い光でも充分光らせることができる。 The operation display panel 16 also has a pressing operation button section 28 and a light emission display section 29. Inside the operation display panel 16, there is a control board unit B32 on which a switch 30, a light emitting element 31 and the like are mounted. Mounted. An operation member 36 having a light guide path 34 for guiding the light of the light emitting element 31 to the light emitting display unit 29 and a button unit 35 for pressing the switch 30 is provided between the operation display panel 16 and the back cover 33. Provided. Since the pressing operation button portion 28 does not have the transparent resin portion 19 and only the film 20 exists, the switch 30 can be operated with a light operation force. Further, the light emitting display portion 29 is printed with high transparency so that even the weak light of the light emitting element 31 can be sufficiently illuminated.
使用者が電源入りボタン（押圧操作ボタンの１つ）を押すと、液晶パネル２５には例えば図１に示すような表示が現れ、前記透明ガラス板２２を通して表示が見える。次に使用者が例えば「わたし流」と表示された領域の透明ガラス板の表面を指で触ると、図示はしないが例えば「洗い」の回数や時間の設定表示画面になったり、水位の設定などの表示になったりして、次々に下位の設定に進んでいく。このように表示画面を直接触って階層的に設定するのはタッチパネル方式と呼ばれ、透明ガラス板２２の裏面に接着された透明電極２４によって、指がガラスに触れた時の静電容量の変化を検知することで、指が触れた位置を特定し、表示内容を操作に応じて進めていくことができる。 When the user presses the power-on button (one of the pressing operation buttons), for example, a display as shown in FIG. 1 appears on the liquid crystal panel 25 and the display is visible through the transparent glass plate 22. Next, for example, if the user touches the surface of the transparent glass plate in the area where “My Style” is displayed with a finger, for example, the screen for setting the number of times and time for “washing” or setting the water level is displayed. Etc., and proceed to lower settings one after another. Such a hierarchical setting by directly touching the display screen is called a touch panel method, and the capacitance changes when the finger touches the glass by the transparent electrode 24 bonded to the back surface of the transparent glass plate 22. By detecting, the position touched by the finger can be specified, and the display content can be advanced according to the operation.
図２に従来例の操作表示パネル５０を示すが、中央の表示窓は液晶パネル５１の表示内容を、透明樹脂とその表面にインサート成形されたフィルムを通して見せるだけであり、表示場所も決まっているので、表示内容が増えると表示文字は小さくなってしまう。また「コース」ボタン５２などの設定ボタンが多数並び、使用者がどこを押したらいいのかわかりにくく、操作性が悪い、表示文字も小さく視認性が悪いという課題がある。 FIG. 2 shows a conventional operation display panel 50. The display window in the center only shows the display content of the liquid crystal panel 51 through a transparent resin and a film formed by insert molding on the surface, and the display location is also determined. Therefore, as the display contents increase, the displayed characters become smaller. In addition, there are many setting buttons such as “Course” button 52, which makes it difficult to understand where the user should press, poor operability, small display characters, and poor visibility.
そこで、上述したように操作表示パネル１６に開口窓２１を設け、その裏面側に透明電極２４を接着した透明ガラス板２２を弾性体２３を介して取り付けることにより、使用者が表示画面を直接触って階層的に設定することができ、その結果、固定された操作ボタンを多数設ける必要が無くなって、操作ボタンを大幅に減らすことができる。また液晶パネル２５には、今操作する時に必要な表示のみを絞って表示したらいいので、表示内容を少なくかつ大きくでき、操作性、視認性の向上が図れる。 Therefore, as described above, the operation display panel 16 is provided with the opening window 21, and the transparent glass plate 22 with the transparent electrode 24 bonded to the back side thereof is attached via the elastic body 23, so that the user directly touches the display screen. Therefore, it is not necessary to provide a large number of fixed operation buttons, and the number of operation buttons can be greatly reduced. Further, since only the display necessary for the current operation should be displayed on the liquid crystal panel 25, the display content can be reduced and increased, and operability and visibility can be improved.
透明ガラス板２２の裏側には、液晶パネル２５や制御ユニット基板Ａなどの電装部品があり、防水が必要となる。そこで略矩形形状の透明ガラス板２２の外周部を枠形状の弾性体２３で覆い、この弾性体を介して略矩形形状の開口窓２１の裏面に取り付けている。開口窓２１の上辺３７の内部、および下辺３８の内部では、透明ガラス板２２の表面側、裏面側、端面側の３方向とも弾性体２３を介して、透明ガラス板２２が操作表示パネル１６と液晶取付台２６の間に防水的に取付けられる。また開口窓２１の左辺３９の内部、および右辺４０の内部では、透明ガラス板２２の裏面側、端面側の２方向とも弾性体２３を介して、透明ガラス板２２が操作表示パネル１６と液晶取付台２６の間に防水的に取付けられる。左右辺に関しては、透明ガラス板２２の表面側を弾性体２３で覆っていないが、透
明ガラス板２２左右の外側部分において、弾性体２３が操作表示パネル１６に押し付けられる構成となっているため、防水性は確保される。このような構成により、透明ガラス２２と操作表示パネル１６との間の防水性は確保しつつ、開口窓２１の左右辺の透明ガラス板２２に対する段差を少なくすることができる。段差が少なくなれば、デザイン的にすっきりとした見た目になるとともに、視野角も広がるというメリットがある。なお本実施例では、透明ガラス板２２の左右辺の前面部を弾性体２３で覆わない構成としたが、上下辺を同構成にしても同様の効果が得られる。
On the back side of the transparent glass plate 22, there are electrical components such as the liquid crystal panel 25 and the control unit substrate A, and waterproofing is required. Therefore, the outer periphery of the substantially rectangular transparent glass plate 22 is covered with a frame-shaped elastic body 23 and attached to the back surface of the substantially rectangular opening window 21 via this elastic body. In the inside of the upper side 37 of the opening window 21 and the inside of the lower side 38, the transparent glass plate 22 is connected to the operation display panel 16 via the elastic body 23 in the three directions of the front side, the back side, and the end side of the transparent glass plate 22. The liquid crystal mounting base 26 is waterproofly attached. Further, in the inside of the left side 39 and the inside of the right side 40 of the opening window 21, the transparent glass plate 22 is attached to the operation display panel 16 and the liquid crystal through the elastic body 23 in both the back side and the end side of the transparent glass plate 22. It is attached between the bases 26 in a waterproof manner. Regarding the left and right sides, the surface side of the transparent glass plate 22 is not covered with the elastic body 23, but the elastic body 23 is pressed against the operation display panel 16 at the left and right outer portions of the transparent glass plate 22. Waterproofness is ensured. With such a configuration, it is possible to reduce the level difference with respect to the transparent glass plate 22 on the left and right sides of the opening window 21 while ensuring the waterproofness between the transparent glass 22 and the operation display panel 16. If there are fewer steps, there will be a clear design and a wider viewing angle. In addition, in the present Example, it was set as the structure which does not cover the front part of the right-and-left side of the transparent glass plate 22 with the elastic body 23, but the same effect is acquired even if an up-and-down side is the same structure.
操作表示パネル１６の裏面の開口窓２１の４隅にはボス４１が設けられ、液晶取付台２６、および裏面カバー３３がビス締結される。ビス締結状態では、弾性体２３が液晶取付台２６で押し付けられて透明ガラス板２２および操作表示パネル１６と密着するので、開口窓２１の防水性が確保される。よって使用者が誤って開口窓２１に水をこぼしたりしても、内部にある液晶パネル２５や制御基板ユニットＡ２７などの電装部品に水が付着することが無く、安全に守る。なお本実施例では液晶取付台２６、および裏面カバー３３が共締めされる例を示したが、液晶取付台２６を単独で操作表示パネル１６にビス締結しても同様の効果が得られる。 Bosses 41 are provided at the four corners of the opening window 21 on the back surface of the operation display panel 16, and the liquid crystal mounting base 26 and the back surface cover 33 are screwed together. In the screw fastening state, the elastic body 23 is pressed by the liquid crystal mounting base 26 and is in close contact with the transparent glass plate 22 and the operation display panel 16, so that the waterproof property of the opening window 21 is ensured. Therefore, even if a user accidentally spills water on the opening window 21, water does not adhere to the electrical components such as the liquid crystal panel 25 and the control board unit A27 inside, and the user is safely protected. In the present embodiment, an example in which the liquid crystal mounting base 26 and the back cover 33 are fastened together is shown, but the same effect can be obtained even if the liquid crystal mounting base 26 is screwed to the operation display panel 16 alone.
また弾性体２３の下辺側には、透明ガラス板２２端面に相当する位置に開口部２３ａが設けられているとともに、左右外側には溝部２３ｂが設けられている。これにより、万が一、弾性体２３についた傷や操作表示パネル１６のショートショットなどの部品不良などによって開口窓２１のシールが破られた場合にも、開口部２１の下辺より浸入した水は、弾性体の下辺に設けられた開口部２３ａを通って、下方に抜けていき、透明ガラス板２２裏面の透明電極２４部にいくことはない。一方、左右辺より浸入した水も、弾性体２３に設けられた溝部２３ｂを通って、下方に抜けていく構成としているため、制御基板ユニットＢ３２などの充電部に水がいくことはない。このような構成により、安全性を確保している。 An opening 23a is provided on the lower side of the elastic body 23 at a position corresponding to the end surface of the transparent glass plate 22, and a groove 23b is provided on the left and right outer sides. As a result, even if the seal of the opening window 21 is broken due to a scratch on the elastic body 23 or a defective part such as a short shot of the operation display panel 16, water that has entered from the lower side of the opening 21 is elastic. It passes through the opening 23a provided on the lower side of the body and goes downward, and does not go to the transparent electrode 24 on the back surface of the transparent glass plate 22. On the other hand, since water that has entered from the left and right sides passes through the groove 23b provided in the elastic body 23 and flows downward, water does not flow to the charging unit such as the control board unit B32. Such a configuration ensures safety.
加えて、操作表示パネル１６の上下辺には立壁１６ａが設けられており、前記立壁１６ａは弾性体２３の端面を覆う構成としている。これにより、操作表示パネル１６の周囲より水がかかった場合にも、弾性体２３の端面に水がかかるのを防いでくれるため、弾性体２３の隙間より操作表示パネル１６内部へ水が浸入し、充電部に水がかかるといった可能性を排除できる。 In addition, a vertical wall 16 a is provided on the upper and lower sides of the operation display panel 16, and the vertical wall 16 a is configured to cover the end surface of the elastic body 23. Thus, even when water is splashed from the periphery of the operation display panel 16, water enters the operation display panel 16 through the gap between the elastic bodies 23 to prevent water from splashing on the end face of the elastic body 23. The possibility that water will be applied to the charging part can be eliminated.
また、透明ガラス板２２が弾性体２３を介して開口窓２１の裏面に取り付けることで、外部から加わる衝撃でガラスが破損することも防止できる。透明ガラス板２２には、例えば使用者が何かを落とした時に衝撃荷重が加わる。また製品が包装状態で使用者宅に届けられる物流の途中で、積荷状態から落下したり転倒したりされた時でも同じく衝撃力が加わる。操作表示パネル１６は樹脂製で少しは衝撃吸収はするが、透明ガラス板２２は硬いけれど衝撃には弱いものである。よって透明ガラス板２２の外周に弾性体２３を配置させることで柔構造となり、外部から衝撃が加わっても破損を防げる。 Moreover, it can also prevent that a glass breaks with the impact added from the outside by attaching the transparent glass plate 22 to the back surface of the opening window 21 via the elastic body 23. FIG. An impact load is applied to the transparent glass plate 22 when the user drops something, for example. Also, when the product is delivered to the user's home in a packaged state, an impact force is also applied when the product is dropped or falls from the loaded state. Although the operation display panel 16 is made of resin and absorbs a little impact, the transparent glass plate 22 is hard but weak against impact. Therefore, by arranging the elastic body 23 on the outer periphery of the transparent glass plate 22, a flexible structure is obtained, and damage can be prevented even if an impact is applied from the outside.
ガラスはＡＢＳ樹脂に比べ線膨張係数が１オーダー小さい。製品が使用者宅で設置される場所が夏場、冬場では気温差が大きく、また倉庫で包装状態で保管された状態でも季節、地域差でかなりの温度差が生じる。線膨張係数の違いが大きい部品同士を組み合わせる時は、熱膨張差による変形を吸収する構造にしないと部品の破損を招くことがある。そこで本実施例では、透明ガラス板２２は弾性体２３を介して開口窓２１の裏面に取り付けることで、熱膨張差で透明ガラス板２２と操作表示パネル１６や液晶取付台２６との間に寸法変化が生じても、弾性体２３によって吸収され部品の破損を防げる。 Glass has a linear expansion coefficient one order of magnitude smaller than that of ABS resin. There is a large temperature difference in summer and winter when the product is installed at the user's home, and there is a considerable temperature difference depending on the season and region even when the product is stored in a packed state in the warehouse. When components having large differences in linear expansion coefficients are combined, damage to the components may occur unless the structure absorbs deformation due to thermal expansion differences. Therefore, in this embodiment, the transparent glass plate 22 is attached to the back surface of the opening window 21 via the elastic body 23, so that the dimension between the transparent glass plate 22 and the operation display panel 16 or the liquid crystal mounting base 26 is different due to the difference in thermal expansion. Even if a change occurs, it is absorbed by the elastic body 23 and can be prevented from being damaged.
