【考案の詳細な説明】 本考案は本体前面開口を下向きに枢動する扉体にて閉塞
する食器洗浄機の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a dishwasher in which the front opening of the main body is closed by a door body that pivots downward.

従来この種の洗浄機は扉を開放しラックに食器を入れこ
のラックを洗浄室内へ送り込み扉を閉め食器の洗浄を行
ない、終了後扉を再び開放してラックを取出す。Conventionally, in this type of washing machine, the door is opened, dishes are placed in a rack, the rack is sent into a washing chamber, the door is closed, the dishes are washed, and after the washing is finished, the door is opened again and the rack is taken out.

このときに扉は特に閉操作を軽くする為に内部に発条を
使用し該発条は常時扉を閉めようとする方向に働いてい
る。At this time, the door uses a spring inside to particularly ease the closing operation, and the spring always works in the direction of closing the door.

扉を開放するとその停止位置は扉の重さと発条の強さが
釣り合った位置であり、発条を弱くすれば扉の重さが勝
るため規定の位置、即ち本体に対して垂直状態で停止す
るが、扉を閉めるときの力が増大し、逆に発条を強くす
ると扉を閉めるときの力は少なくてすむが開放したとき
に規定の位置まで開かずラックを取出す時に扉を手で押
えて行なう必要があった。When the door is opened, the stop position is a position where the weight of the door and the strength of the spring are balanced, and if the spring is weakened, the weight of the door will outweigh the door, so it will stop at the specified position, that is, perpendicular to the main body. , the force required to close the door increases; conversely, if the force is made stronger, the force required to close the door is reduced, but when the rack is opened, it does not open to the specified position, and the door must be held down by hand when removing the rack. was there.

従って微妙な発条の調整を必要とし組立作業性が極めて
容易でなかった。Therefore, delicate spring adjustments were required, making assembly work extremely difficult.

本考案は斯かる点に鑑み、微妙な発条の調整を必要とせ
ずに扉を決まった開放位置に保持し、しかも扉開閉動作
が円滑に行なわれる様にした食器洗浄機を提供するにあ
り、以下に本考案の一実施例を図面に基づき説明する。In view of the above, the present invention aims to provide a dishwasher that maintains the door in a fixed open position without requiring delicate spring adjustments, and that allows the door to open and close smoothly. An embodiment of the present invention will be described below based on the drawings.

１は前面開口を下向きに枢動する扉２にて閉塞された上

ンク７底部には前記モーター４にて駆動される循環ポン
プ８が配設される水槽９が凹窪形或されている。Reference numeral 1 denotes a main body of the dishwasher, which has an upper washing chamber 3 whose front opening is closed by a door 2 that pivots downward, and a lower machine room 5 in which a pump motor 4 etc. are arranged. A cleaning nozzle 6 is rotatably housed in the cleaning tank 7, and a water tank 9 in which a circulation pump 8 driven by the motor 4 is installed is formed in a concave shape at the bottom of the cleaning tank 7.

また水槽９の上方には洗浄ノズル６より噴水された洗浄
水に混った汚物がポンプ８に吸入されない様にフィルタ
ー１０を配置している。Further, a filter 10 is arranged above the water tank 9 to prevent dirt mixed in the washing water sprayed from the washing nozzle 6 from being sucked into the pump 8.

更に洗浄ノズル６の上方には被洗浄物１１を収納せるラ
ツク１２がレール１３上に載置される。Further, above the cleaning nozzle 6, a rack 12 for storing an object to be cleaned 11 is placed on a rail 13.

而して、前記扉２はトーションバーを使用した付勢発条
１４の作用によって常時閉塞位置に付勢される。Thus, the door 2 is always urged to the closed position by the action of the urging spring 14 using a torsion bar.

ローラー停止部分１７Ｂを連続形或している。15 fixes one end to the side of the door 2 and attaches a stopper piece 1 to the other end.
5A, an arc-shaped arm 16, a roller rotatably supported on the other end surface of the arm 15, and 17, a mounting plate 19 fixed to a flange 20 that frames the opening on the main body side, and a screw corresponding to the roller 16; The fixed holding plate spring has a continuous upwardly curved roller receiving portion 17A and a downwardly curved roller stop portion 17B.

１８はストツパ一片１５Ａの規制部で、前記取付け板１
９が兼用しているが、この規制部１８はフランジ２０等
であってもよい。Reference numeral 18 denotes a regulating portion of the stopper piece 15A, which is attached to the mounting plate 1.
9 is also used, but this regulating portion 18 may also be a flange 20 or the like.

なお規制部１８にストッパー片１５Ａが当接したときロ
ーラー１６が停止部分１７Ｂに嵌まり込み、このとき板
発条１７によってローラー１６に押圧力が作用する様に
する。When the stopper piece 15A comes into contact with the regulating part 18, the roller 16 is fitted into the stop part 17B, and at this time a pressing force is applied to the roller 16 by the plate spring 17.

次に扉２の開閉動作を説明する。Next, the opening/closing operation of the door 2 will be explained.

第２図に示す様に扉２が閉まっている状態から人力によ
って扉２を開放していくと扉２が完全に開く若干前でロ
ーラー１６が保持板発条１７の受入部分１７Ａに当接し
これを押上げていく。As shown in FIG. 2, when the door 2 is manually opened from the closed state, the roller 16 comes into contact with the receiving portion 17A of the retaining plate spring 17 slightly before the door 2 is completely opened. Push up.

更に扉２が開放されていくとストッパー片１５Ａは規制

決まった停止位置に保持される。As the door 2 is further opened, the stopper piece 15A comes into contact with the regulating part 18, and at this point, the opening of the door 2 is regulated, and the roller 16 is fitted into the stop part 17B of the retaining plate spring 17, and the plate springs are overlapped. 17 acts on the roller 16, the door 2 is held at a fixed stop position as shown in FIG. 3, regardless of the force of the biasing spring 14 acting to close the door 2. .

また扉２を若干閉めることによってローラー１６は停止
部分１７Ｂから外れ、更に受入れ部分１７Ａを押上げな
がら該受入部分１７Ａから外れると後は付勢発条１４の
作用によって扉２は第２図の状態に復帰する。Further, by slightly closing the door 2, the roller 16 comes off from the stop portion 17B, and when it comes off the receiving portion 17A while pushing up the receiving portion 17A, the door 2 is placed in the state shown in FIG. 2 by the action of the biasing spring 14. Return.

本考案は以上の如く扉を常時閉塞位置に付勢する付勢発
条の微妙な調整を全く必要とせずアーム他端に形戊せる
ストッパー片が規制部に当接した時点でローラーが保持
板発条の停止部分に嵌まり込み重ねて板発条の押圧力が
ローラーにかかるため扉は必ず決まった停止位置を確実
に保持できる利点を奏する。As described above, the present invention does not require any delicate adjustment of the biasing spring that always biases the door to the closed position, and the roller activates the retaining plate when the stopper piece that can be formed at the other end of the arm comes into contact with the regulating part. This has the advantage that the door can be reliably held at a fixed stopping position because the pressing force of the plate springs is applied to the roller by fitting into the stopping part of the door and stacking them on top of each other.

また保持板発条は上向きにアールの受入部分と下向きに
アールの停止部分を形或しているからローラーの受入れ
及び回動が円滑に行なわれる利点を奏する。Further, since the retaining plate spring has an upwardly curved receiving portion and a downwardly curved stopping portion, there is an advantage that the roller can be smoothly received and rotated.
