Description

本発明は、食器等を洗浄する食器洗い機に関するもので、特に扉開閉機構に関するものである。 The present invention relates to a dishwasher for cleaning dishes and the like, and more particularly to a door opening / closing mechanism.

従来のこの種の食器洗い機は、図１０、１１に示すように構成されている（例えば、特許文献１参照）。 A conventional dishwasher of this type is configured as shown in FIGS. 10 and 11 (see, for example, Patent Document 1).

以下、その構成について説明する。食器洗い機は、食器等の被洗浄物を洗浄槽１０１に収納し、洗浄槽１０１に設けた前面開口部１０２を、上扉体１０３と下扉体１０４により閉塞してから、洗浄ポンプを運転し、洗浄水を噴射することにより、被洗浄物の洗浄およびすすぎ工程を行うようになっている。下扉体１０４は、下扉支持部材１０５により、前面開口部１０２の前下方に、その内面が上向き水平となる位置まで回転開閉する構成となっており、下扉体１０４の内面に食器かごを引き出せる構成となっている。一方上扉体１０３は、上扉支持部材１０６により、本体１０７の上方空間に開閉する構成となっており、上扉体１０３の開閉に必要な高さを小さく抑え、高さの小さい場所にでも、設置が可能となっており、また開成状態における上扉体１０３の前面開口部１０２より前方への突出長さを小さくできるので、被洗浄物の出し入れ等に支障がない構成となっている。 Hereinafter, the configuration will be described. The dishwasher stores objects to be cleaned, such as tableware, in the washing tank 101, and the front opening 102 provided in the washing tank 101 is closed by the upper door body 103 and the lower door body 104, and then the washing pump is operated. The cleaning and rinsing steps of the object to be cleaned are performed by spraying the cleaning water. The lower door body 104 is configured to be opened and closed by a lower door support member 105 in front of and below the front opening 102 to a position where the inner surface is upwardly horizontal, and a table basket is attached to the inner surface of the lower door body 104. It can be pulled out. On the other hand, the upper door body 103 is configured to be opened and closed in the upper space of the main body 107 by the upper door support member 106, and the height necessary for opening and closing the upper door body 103 is kept small, even in a place with a small height. In addition, since the length of the protrusion from the front opening 102 of the upper door body 103 in the opened state to the front can be reduced, the structure is such that there is no hindrance to putting in and out the object to be cleaned.

また、下扉支持部材１０５と上扉支持部材１０６は連動部１０８により連結されており、連動して開閉する構成となっている。連動部１０８は、第１のスプリング１０９と第２のスプリング１１０により扉体が開放するよう付勢されており、押しボタンスイッチ１１１によりロック手段１１２の洗浄槽１０１に設けた係止部１１３への係り止めを解除することで、扉体は開成状態まで自動的に開放する。さらに、第３のスプリング１１４により付勢された減速部材１１５が上扉支持部材１０６と当接することで扉体閉塞方向に付勢する構成となっており、扉体開放途中から開放速度を抑制し、扉体全開時の衝撃を緩和することが可能となっている。 Further, the lower door support member 105 and the upper door support member 106 are connected by an interlocking portion 108, and are configured to open and close in conjunction. The interlocking portion 108 is biased so that the door body is opened by the first spring 109 and the second spring 110, and the push button switch 111 connects the locking means 112 to the locking portion 113 provided in the cleaning tank 101. By releasing the locking, the door automatically opens to the open state. Further, the speed reducing member 115 biased by the third spring 114 is biased in the door closing direction by contacting the upper door support member 106, and the opening speed is suppressed from the middle of the door opening. It is possible to alleviate the impact when the door is fully open.

その結果、上・下扉体１０３、１０４が自動的に連動して開放する使い勝手の良さと、扉体全開時の衝撃やリバウンドを抑えた高品質な食器洗い機を実現できる。
特開２００３−３０４９９４号公報 As a result, it is possible to realize a high-quality dishwasher in which the upper and lower door bodies 103 and 104 are automatically opened in conjunction with each other and the impact and rebound when the door body is fully opened are suppressed.
JP 2003-304994 A

上記食器洗い機の扉体開閉構成では、扉体は開放するにつれて扉体の自重による開放方向へのモーメントが大きくなり、扉体へ付勢する減速力は扉体の開放量に比例して大きくする必要がある。ただし、開放の途中であまり大きな減速力を与えると、扉体の動作が途中止まりしてしまい、下扉体１０４が開放途中の大きく浮き上がった状態で停止してしまう可能性がある。そこで、扉体の開放途中での減速力は扉体が確実に開放するよう小さく設定し、扉体の開成状態近傍で減速力を著しく増大させることが望ましい。そうすれば、減速力が扉体の開放力に勝って下扉体１０４が浮き上がってしまうことがあっても、それは減速力が著しく増大した後の扉体開成状態近傍であるため、下扉体１０４への食器かごの引き出し等、実使用上支障が無いからである。 In the door body opening / closing configuration of the dishwasher, as the door body opens, the moment in the opening direction due to the weight of the door body increases, and the deceleration force urging the door body increases in proportion to the opening amount of the door body. There is a need. However, if a very large deceleration force is applied during the opening, the operation of the door body may be stopped halfway, and the lower door body 104 may be stopped in a state of being largely lifted during the opening. Therefore, it is desirable that the deceleration force during the opening of the door body is set to be small so that the door body is surely opened, and the deceleration force is remarkably increased in the vicinity of the opened state of the door body. Then, even if the deceleration force overcomes the opening force of the door body and the lower door body 104 floats up, it is in the vicinity of the door body opened state after the deceleration force is significantly increased. This is because there is no hindrance in actual use such as pulling out the tableware basket to 104.

しかしながら、上記従来の扉体開閉構成では、減速力を第３のスプリング１１４の付勢力にのみ依存しているため、減速力を比例的に増加させることしかできず、著しく減速力を増加させることは不可能である。その結果、扉体を確実に全開させるためには、扉体全開時の衝撃やリバウンドを十分に抑えることができないという課題を有していた。 However, in the above conventional door body opening / closing configuration, the deceleration force depends only on the urging force of the third spring 114, so that the deceleration force can only be increased proportionally, and the deceleration force can be significantly increased. Is impossible. As a result, in order to reliably open the door body, there has been a problem that the impact and rebound when the door body is fully open cannot be sufficiently suppressed.

本発明は、上記従来の課題を解決するもので、扉体の自動開放を確実に実現し、且つ扉体全開時の衝撃やリバウンドを確実に抑えた高品質な扉体の開閉動作を実現することを目的としている。 The present invention solves the above-described conventional problems, and realizes automatic opening of the door body, and realizes a high-quality door opening / closing operation that reliably suppresses impact and rebound when the door body is fully opened. The purpose is that.

以上のように構成された食器洗い機についてその作用を説明する。 The operation of the dishwasher configured as described above will be described.

押しボタンスイッチ１７を押すことで、係止部１８から、ロック手段１９が解除され、第１のスプリング２８、と第３のスプリング３４によって付勢された連動部２３が扉体開放方向に動作する。また、第１のスプリング２８は、上扉体６に対して、下扉体７を開放する方向に付勢しており、かつ、第４の連結点２２があそびを有していることで、開放初
期は下扉体７のみが開放し、上扉体６は閉成位置に留まっている。 By pushing the push button switch 17, the locking means 19 is released from the locking portion 18, and the interlocking portion 23 biased by the first spring 28 and the third spring 34 operates in the door body opening direction. . Further, the first spring 28 urges the upper door body 6 in the direction of opening the lower door body 7 and the fourth connecting point 22 has a play. Initially, only the lower door body 7 is opened, and the upper door body 6 remains in the closed position.

長穴部２２ａが円筒連結軸２２ｂのあそび領域を動作しきると、長穴部２２ａと円筒連結軸２２ｂが連結され、上扉支持部材１１に連動部２３に付勢されていた扉体開放方向への力が伝達される。それに加えて、第２のスプリング３１による第２の動作規制部１４への扉体開放方向への付勢力により、上扉体６の自重による扉体閉塞方向へのモーメントに打ち勝って、上・下扉体６、７は連動して閉成状態から下扉支持部材１５が第１のストッパー部１６と当接する開成状態まで自動的に開放する。この時、下扉体７は、その内面が上向き水平となる位置まで回転している。 When the long hole portion 22a moves completely in the play area of the cylindrical connecting shaft 22b, the long hole portion 22a and the cylindrical connecting shaft 22b are connected, and the upper door support member 11 is biased by the interlocking portion 23 in the door opening direction. The power of is transmitted. In addition, the urging force of the second spring 31 to the second movement restricting portion 14 in the door opening direction overcomes the moment in the door closing direction due to the weight of the upper door 6, The door bodies 6 and 7 are automatically opened from the closed state to the open state where the lower door support member 15 contacts the first stopper portion 16. At this time, the lower door body 7 is rotated to a position where the inner surface is upward and horizontal.

上扉体６は、開放初期は開口部５の略円弧形状の中央部に対して、円弧の法線方向に動作するので、シール部材８と擦れることなく開放することができる。また、開放途中から開成にかけては、第１の動作規制部１３の回転角度が、第２の動作規制部１４の回転角度より大きくなるため、上扉体６は本体１上部に回りこむよう開放する。本体１の上部形状、及び上扉体６は略円弧形状をしているので、上扉体６を略円弧形状に沿わすように開放させることで、上扉体６の開放に必要な本体１上部空間を最小限に抑えることが可能となっている。 Since the upper door body 6 operates in the normal direction of the arc with respect to the substantially arc-shaped central portion of the opening 5 in the initial stage of opening, the upper door body 6 can be opened without rubbing against the seal member 8. Moreover, since the rotation angle of the 1st operation control part 13 becomes larger than the rotation angle of the 2nd operation control part 14 from the middle of opening to opening, the upper door body 6 opens so that it may wrap around to the main body 1 upper part. . Since the upper shape of the main body 1 and the upper door body 6 have a substantially arc shape, the main body 1 necessary for opening the upper door body 6 by opening the upper door body 6 along the substantially arc shape. It is possible to minimize the upper space.

また、上扉体６の外形ラインと、開口部５上端より後方の本体１の外形ラインは略同一の円弧となっており、開成状態の上扉体６の開口部５より前方への突出を無くし、且つ、本体１背面より後方への突出も無くすことが可能となっている。これにより、被洗浄物の出し入れ時に上扉体６が邪魔にならない使い勝手の良さと、本体１後方に設置空間を必要としない設置性の良さを両立することが可能となっている。 Further, the outer shape line of the upper door body 6 and the outer shape line of the main body 1 behind the upper end of the opening 5 have substantially the same arc, and project forward from the opening 5 of the opened upper door body 6. Further, it is possible to eliminate the rearward protrusion from the back surface of the main body 1. Thereby, it is possible to satisfy both the ease of use in which the upper door body 6 does not get in the way when the object to be cleaned is taken in and out and the ease of installation that does not require an installation space behind the main body 1.

扉体が開放するにつれて、下扉体７の自重による開放方向へのモーメントは増加し、上扉体６の自重による扉体閉塞方向へのモーメントは減少するため、上・下扉体６、７の自重による扉体連動機構全体としてのモーメントは、扉体閉成時は扉体閉塞方向に働いているが、扉体が開放するにつれて、閉塞方向のモーメントは小さくなり、開放途中で、モーメントの働く方向が逆転し、それ以降は開放するにつれて、扉体開放方向へのモーメントは大きくなる。そこで、開放途中から開成にかけては、第２のスプリング３１が、第２の動作規制部１４を扉体閉塞方向へ付勢し、第３のスプリング３４が連動部２３を扉体閉塞方向へ付勢するよう構成しており、扉体の開放速度を抑え、扉体全開時の衝撃を緩和している。 As the door body opens, the moment in the opening direction due to the weight of the lower door body 7 increases and the moment in the door body closing direction due to the weight of the upper door body 6 decreases, so the upper and lower door bodies 6, 7 The moment of the door interlocking mechanism as a whole due to its own weight works in the door closing direction when the door is closed, but as the door opens, the moment in the closing direction decreases, As the working direction reverses and thereafter opens, the moment in the door opening direction increases. Therefore, from the middle of opening to the opening, the second spring 31 biases the second operation restricting portion 14 in the door closing direction, and the third spring 34 biases the interlocking portion 23 in the door closing direction. The door body opening speed is suppressed, and the impact when the door body is fully opened is mitigated.

しかし、第２のスプリング３１と第３のスプリング３４は、上・下扉体６、７が確実に自動的に開放するよう設定する必要があり、扉体全開時の衝撃緩和も両立させるのは難しい。また、扉体が確実に全開し、且つ、扉体全開時の衝撃を確実に緩和するためには、扉体全開状態近傍で急激に扉体開放速度を抑制し、全開時の衝撃を緩和することが必要であり、第２のスプリング３１と第３のスプリング３４による減速では、力が比例的に徐々に変化するため、急激に扉体開放速度を抑制することは難しい。 However, the second spring 31 and the third spring 34 need to be set so that the upper and lower door bodies 6 and 7 are automatically opened, and the impact relaxation when the door body is fully opened is compatible. difficult. In addition, in order to ensure that the door body is fully opened and that the shock when the door body is fully opened is reliably mitigated, the door body opening speed is rapidly suppressed near the door body fully opened state, and the impact when fully opened is mitigated. In the deceleration by the second spring 31 and the third spring 34, since the force gradually changes proportionally, it is difficult to rapidly suppress the door opening speed.

そこで、扉体開放途中から減速部材３６により、上扉支持部材１１に扉体閉塞方向への付勢力を与える構成としている。減速部材３６は、上・下扉体支持部材１１、１５と、連動部２３による連動機構の自動開放動作とは全く独立しているため、設定の自由度が高く、また、連動機構全体として開放方向へのモーメントが大きくなる扉体開放途中から、扉体閉塞方向へのモーメントを上扉支持部材１１に加え、さらに、第４のスプリング４０による減速部材３６への付勢力は、扉体が開放するにつれて大きくなり、また、減速部材３６と摺動部３７の接点も扉体が開放するにつれて第４の支持軸３５に近づくため、それにつれて大きくなり、それらの相乗効果により、扉体開成状態近傍で、急激に大きな扉体閉塞方向への力を上扉支持部材１１に加えることが可能であり、開放速度の抑制と、扉体全
開時の衝撃の緩和をより効果的に実現できる。 Therefore, the urging force in the door closing direction is applied to the upper door support member 11 by the speed reduction member 36 in the middle of opening the door body. The deceleration member 36 is completely independent of the automatic opening operation of the interlocking mechanism by the upper / lower door body support members 11 and 15 and the interlocking portion 23, so that the degree of freedom of setting is high, and the interlocking mechanism as a whole is opened. The moment in the door body closing direction is applied to the upper door support member 11 from the middle of opening the door body, and the urging force of the fourth spring 40 to the speed reduction member 36 causes the door body to open. Further, the contact point between the speed reduction member 36 and the sliding portion 37 approaches the fourth support shaft 35 as the door body opens, so that the contact point between the speed reduction member 36 and the sliding portion 37 increases with the synergistic effect. Thus, it is possible to apply a large force in the closing direction of the door body to the upper door support member 11, and it is possible to more effectively realize the suppression of the opening speed and the mitigation of the impact when the door body is fully opened.

上・下扉体６、７の全開後、下扉体７の内面上に食器かご４を引出し、被洗浄物をセットする。食器かご４を下扉体７内面上に引出す構成をとっているので、食器３等の被洗浄物から垂れた汁、水滴が機外へ流出するのを防止することができる。 After the upper and lower door bodies 6 and 7 are fully opened, the tableware basket 4 is pulled out on the inner surface of the lower door body 7 to set an object to be cleaned. Since the tableware basket 4 is pulled out onto the inner surface of the lower door body 7, it is possible to prevent the juice and water droplets dripping from the object to be cleaned such as the tableware 3 from flowing out of the machine.

続いて、食器かご４を洗浄槽２内に収納し、下扉体７を閉塞する。上扉体６と下扉体７は連動して開閉する構成となっているので、上扉体６も同時に閉塞される。減速部材３６の上扉支持部材１１への扉体閉塞方向への付勢力は、全開状態近傍で大きくしているため、下扉体７を閉塞する起動力が小さくて良く、操作感が良い。 Then, the tableware basket 4 is accommodated in the washing tank 2 and the lower door body 7 is closed. Since the upper door body 6 and the lower door body 7 are configured to open and close in conjunction, the upper door body 6 is also closed simultaneously. Since the biasing force in the door closing direction to the upper door support member 11 of the deceleration member 36 is increased in the vicinity of the fully opened state, the activation force for closing the lower door body 7 may be small, and the operation feeling is good.

扉体の閉塞途中において、第４の連結点２２のあそびによる上扉体６のがたつきをガイド突起部２４とガイド溝部２５により規制しているので、下扉体７に対する上扉体６の位置がぐらつかず安定している。その結果、閉塞動作において、上扉体６が下扉体７に先行して閉成位置に到達するという所定動作を確実に実現できるため、上扉体６に取り付けた扉体間シール部材９を下扉体７に設けた扉体間シール受け７ｂによって確実にシールすることができる。 During the closing of the door body, the rattling of the upper door body 6 due to the play of the fourth connection point 22 is regulated by the guide protrusion 24 and the guide groove 25, so that the upper door body 6 The position is stable and stable. As a result, in the closing operation, the predetermined operation that the upper door body 6 reaches the closed position prior to the lower door body 7 can be realized with certainty. Therefore, the inter-door seal member 9 attached to the upper door body 6 Sealing can be ensured by a door-to-door seal receiver 7b provided on the lower door body 7.

扉体が閉成する直前は、上扉体６が既に閉成しているため、上扉体６による閉成方向のモーメントはゼロとなり、扉体の連動機構に作用するモーメントは、開放方向に急激に大きくなる。前述の開放方向へのモーメントは下扉体７を閉塞するのに必要な力となるので、なるべく小さい方が望ましい。上扉体６の閉成方向へのモーメントを小さくするには、上扉体６を軽くすれば良いが、上扉体６には内部の視認性をよくするため、強化ガラス製の窓１０が設けられており、また上扉体６は構成上軽量化を図るには限界がある。そこで、上扉体６の自重の影響を小さくするために、上扉体６の自重によるモーメントを相殺するように第２の動作規制部１４に第２のスプリング３１が設けられており、上扉体６を軽量化したのと同じ効果を実現している。 Immediately before the door is closed, the upper door 6 is already closed, so the moment in the closing direction by the upper door 6 is zero, and the moment acting on the interlocking mechanism of the door is in the opening direction. It grows rapidly. Since the moment in the opening direction is a force necessary to close the lower door body 7, it is desirable that the moment is as small as possible. In order to reduce the moment in the closing direction of the upper door body 6, the upper door body 6 may be lightened, but the upper door body 6 has a tempered glass window 10 in order to improve the internal visibility. In addition, the upper door body 6 is limited in terms of weight reduction in configuration. Therefore, in order to reduce the influence of the weight of the upper door body 6, the second spring 31 is provided in the second operation restricting portion 14 so as to cancel the moment due to the weight of the upper door body 6. The same effect as the weight reduction of the body 6 is realized.

上扉体６に食器３等が突っ張り、所定閉成位置より上方に存在する時は、図７（ｂ）に示すように下扉突起部４４が第１の上扉突起部４２と当接するため、下扉体７を閉成位置迄閉塞することができない。その結果、ロック手段１９を係止部１８に係止することができず運転できないようになっている。また、この状態で下扉体７を強引に閉塞しようとすると、上扉体６は、下方向に引っ張り込まれるが、下扉突起部４４の上端が第２の上扉突起部４３の下端に引っ掛って、上扉体６の動作を完全に拘束するが可能となり、下扉体７の閉塞を確実に不可能としている。これにより、上扉体６が浮き上がったシールが不完全な状態での運転を防止することが可能となっている。 When the tableware 3 or the like is stretched on the upper door body 6 and exists above the predetermined closed position, the lower door protrusion 44 comes into contact with the first upper door protrusion 42 as shown in FIG. 7B. The lower door body 7 cannot be closed to the closed position. As a result, the locking means 19 cannot be locked to the locking portion 18 and cannot be operated. Further, if the lower door body 7 is to be forcibly closed in this state, the upper door body 6 is pulled downward, but the upper end of the lower door projection 44 is set to the lower end of the second upper door projection 43. As a result, the operation of the upper door body 6 can be completely restrained, and the lower door body 7 cannot be reliably closed. Thereby, it is possible to prevent the operation in a state where the seal with the upper door body 6 lifted up is incomplete.

なお、上述した上・下扉体６、７の開閉機構は、洗浄槽２、及び上・下扉体６、７の左右両側に設けられている。 The opening / closing mechanisms of the upper and lower door bodies 6 and 7 described above are provided on both the left and right sides of the cleaning tank 2 and the upper and lower door bodies 6 and 7.

（実施の形態２）
図８は、第２の実施の形態における食器洗い機の扉体閉成時の斜視図、図９は、同食器洗い機のキッチンに設置した状態の側面図である。本実施の形態は、上扉体４５下端を本体４７の外郭の略円弧形状部分の下方としたもので、上扉体４５が略円弧形状と略平面形状で構成されたものである。他の構成は上記実施の形態１と同様であり、詳細な説明は省略する。 (Embodiment 2)
FIG. 8 is a perspective view when the door of the dishwasher according to the second embodiment is closed, and FIG. 9 is a side view of the dishwasher installed in the kitchen. In the present embodiment, the lower end of the upper door body 45 is located below the substantially arc-shaped portion of the outline of the main body 47, and the upper door body 45 is configured by a substantially arc shape and a substantially planar shape. Other configurations are the same as those of the first embodiment, and detailed description thereof is omitted.

食器洗い機は、シンク４６サイドに設置されるのが一般的であり、本体４７の前面をシンク４６側に向けて設置する側面設置と、本体４７側面をシンク４６側に向けて設置する正面設置とに分けられる。扉体開成状態で、側面設置された食器洗い機においては、下扉
体４８はシンク４６内の水道栓４９に向けて突出し、正面設置された食器洗い機においては、下扉体４８はキッチンカウンタ５０上の調理スペースに覆い被さるよう突出する。 The dishwasher is generally installed on the side of the sink 46, and includes a side installation in which the front surface of the main body 47 is installed facing the sink 46 side, and a front installation in which the side surface of the main body 47 is installed facing the sink 46 side. It is divided into. In the dishwasher installed on the side surface with the door body opened, the lower door body 48 protrudes toward the water tap 49 in the sink 46, and in the dishwasher installed in the front surface, the lower door body 48 is above the kitchen counter 50. Projects to cover the cooking space.

近年、食器洗い機は、大型の食器や調理器具等の洗浄も可能な、大容量タイプの物が望まれており、キッチンカウンタ５０上の限られた設置面積で大容量化を実現するためには、食器洗い機の背を高くする必要があった。しかしながら、上扉体４５の下端を本体４７の外郭の略円弧形状部分の下端部５１近傍に設けた場合、下扉体４８が長くなるため、扉体開成状態で、下扉体４８が水道栓に干渉したり、調理スペースをなくしてしまうという課題を有していた。 In recent years, a dishwasher is desired to be a large-capacity type capable of washing large dishes and cooking utensils, etc. In order to realize a large capacity with a limited installation area on the kitchen counter 50 The dishwasher needed to be taller. However, when the lower end of the upper door body 45 is provided in the vicinity of the lower end portion 51 of the substantially arc-shaped portion of the outline of the main body 47, the lower door body 48 becomes long. It has a problem of interfering with the food or eliminating the cooking space.

本発明の構成によれば、背の高い大容量タイプの食器洗い機において、上扉体４５と下扉体４８の分割を本体４７の外郭の略円弧形状部分の下方に設けることで、下扉体４８を短くすることが可能であり、扉体開成時の下扉体４８の前方への突出を短くできるため上述の課題を解決できる。また、上扉体４５が長くなってしまうことで、扉体開成時に上扉体４５が、開口部５２より前方へ突出してしまうが、食器洗い機の背が高く、開口部５２上端位置が上方に位置しているため、使用者の庫内へのアクセスに上扉体４５が、邪魔になることがない。 According to the configuration of the present invention, in a tall and large-capacity type dishwasher, the lower door body is provided by dividing the upper door body 45 and the lower door body 48 below the substantially arc-shaped portion of the outer shell of the main body 47. 48 can be shortened, and since the protrusion of the lower door body 48 forward when the door body is opened can be shortened, the above-described problems can be solved. Further, since the upper door body 45 becomes longer, the upper door body 45 protrudes forward from the opening 52 when the door is opened, but the dishwasher is tall and the upper end position of the opening 52 is upward. Since it is located, the upper door body 45 does not interfere with the user's access to the interior.

以上のように、本発明にかかる食器洗い機は、扉体が確実に自動的に開放し、且つ扉体全開時の衝撃やリバウンドを十分に抑えることが可能な高品質な扉体の開閉動作を実現することができるものであり、食器洗い機に限らず複数の扉体を使用する洗濯機、洗浄機など各種機器に適用できる。 As described above, the dishwasher according to the present invention can open and close a high-quality door body that can automatically and reliably open the door body and sufficiently suppress the impact and rebound when the door body is fully opened. The present invention can be realized and is applicable not only to a dishwasher but also to various devices such as a washing machine and a washing machine that use a plurality of doors.
