By providing a configuration in which the opening position of the second communication hole is above the opening position of the first communication hole, even if water enters from the opening of the outer box, The possibility of electric leakage is further reduced.

前記外箱は、前記上層のコーナー部を仕切って前記開口部の下側に扉側ロック爪挿入室を形成すると共に、その扉側ロック爪挿入室の一側をその最上部で前記扉側ロック爪挿入室外に連通させる前記扉側ロック爪挿入室内外の連通部を設け、その連通部から前記扉側ロック爪挿入室に前記扉側ロック爪との前記ロック部材の係合部を突出させる構成を採用することにより、連通部が扉側ロック爪挿入室の一側の最上部にあり、しかも、ロック状態では連通部にロック部材の係合部が嵌り込み栓機能を発揮するから、浸水を上層の扉側ロック爪挿入室に止め、外箱の開口部から内部に水が入っても、それが電装部品へ伝い漏電する可能性をさらに低減できる。   The outer box partitions the corner portion of the upper layer to form a door-side lock claw insertion chamber below the opening, and one side of the door-side lock claw insertion chamber is the door-side lock at the top. A configuration in which a communication portion inside and outside the door-side lock claw insertion chamber that communicates with the outside of the claw insertion chamber is provided, and an engagement portion of the lock member with the door-side lock claw is projected from the communication portion into the door-side lock claw insertion chamber. By adopting, the communicating part is at the uppermost part of one side of the door side lock claw insertion chamber, and in the locked state, the engaging part of the lock member fits into the communicating part and exerts the plug function. Even if water enters the interior of the door lock nail insertion chamber on the upper layer from the opening of the outer box, it is possible to further reduce the possibility of leakage to the electrical components.

前記外箱は、前記扉側ロック爪挿入室外の前記上層を前記連通部の近傍で部分的に前記下層よりも外側に張り出す張出部を形成し、その張出部の底部側にドレン孔を設ける構成を採用することにより、上層の扉側ロック爪挿入室から連通部を通して扉側ロック爪挿入室外に浸水しても、連通部の近傍にあるドレン孔から直ちに外箱の外部に排水でき、外箱の開口部から内部に水が入っても、それが電装部品へ伝い漏電する可能性をさらに低減できる。   The outer box forms an overhang portion that projects the upper layer outside the door side lock claw insertion chamber partially outside the lower layer in the vicinity of the communication portion, and a drain hole is formed on the bottom side of the overhang portion. By adopting a configuration in which the door side lock claw insertion chamber is flooded outside the door side lock claw insertion chamber through the communication part, the drain can be immediately drained from the drain hole near the communication part to the outside of the outer box. Even if water enters the inside from the opening of the outer box, the possibility that it is transmitted to the electrical component and leaks can be further reduced.

And the contact part 89 hold | maintained in the initial position (non-engagement position with the door side lock claw 2) shown in FIG. 5 is provided.

上記のように構成した本実施の形態の扉ロック装置は、例えば、扉を有し、それが閉じているときに仕事をする洗濯機、乾燥機、食器洗い機等の機器本体側における戸当り部の内側に設置し、外箱４の開口部３を戸当り部に設けた開口部に配置している。次に、本実施の形態の扉ロック装置の動作を説明する。   The door lock device of the present embodiment configured as described above has, for example, a door stop portion on the apparatus main body side such as a washing machine, a dryer, a dishwasher, etc. that has a door and works when it is closed. The opening 3 of the outer box 4 is arranged in the opening provided in the door stop. Next, the operation of the door lock device of the present embodiment will be described.

図２乃至図６に示す初期状態（扉が開かれて扉側ロック爪２が挿入されていないとき）では、蓋体８４が閉位置（初期位置）に保持されており、外箱４の開口部３は閉じられていると共に、回転レバー２１の係合部５８の先端が閉位置にある蓋体８４の当接部８８に当接（干渉）して、回転レバー２１は非係合位置に保持されている。   In the initial state shown in FIGS. 2 to 6 (when the door is opened and the door-side lock claw 2 is not inserted), the lid 84 is held in the closed position (initial position), and the opening of the outer box 4 The portion 3 is closed, and the tip of the engaging portion 58 of the rotating lever 21 abuts (interferes) with the abutting portion 88 of the lid 84 in the closed position, so that the rotating lever 21 is brought into the non-engaging position. Is retained.

そして、扉が閉じられると、扉側ロック爪２は、その先端と挿入ガイド１８との摺接で、外箱４の開口部３へと誘導されて、その先端で閉位置にある蓋体８４を押圧し、その蓋体８４をダブルトーションバネ８７の付勢力に抗して支点軸８５を中心に下側（内側）に回転させながら、すなわち、蓋体８４（開口部３）を開きながら、その開口部３から外箱４内における上層１０の扉側ロック爪挿入室４１に挿入される。   When the door is closed, the door-side lock claw 2 is guided to the opening 3 of the outer box 4 by sliding contact between the tip and the insertion guide 18, and the lid 84 is in the closed position at the tip. , While rotating the lid 84 downward (inside) around the fulcrum shaft 85 against the urging force of the double torsion spring 87, that is, while opening the lid 84 (opening 3), The opening 3 is inserted into the door lock nail insertion chamber 41 of the upper layer 10 in the outer box 4.

その際、扉側ロック爪２の挿入動作に追従して蓋体８４の右端部（回転側端部）が連通部４２よりも下がるまでは、回転レバー２１は、その係合部５８の先端が蓋体８４の当接部８８や蓋体８４の右端面に当接して、蓋体８４で非係合位置に保持される（係合位置への回転が規制される）が、蓋体８４の右端部が連通部４２よりも下がると、係合部５８の先端が連通部４２に対向する扉側ロック爪２の側面に乗り移って当接し、扉側ロック爪２で非係合位置に保持される（係合位置への回転が規制される）。   At that time, the rotation lever 21 has the tip of the engaging portion 58 until the right end portion (rotation side end portion) of the lid 84 is lowered below the communication portion 42 following the insertion operation of the door side lock claw 2. The abutting portion 88 of the lid 84 and the right end surface of the lid 84 are abutted and held at the non-engagement position by the lid 84 (rotation to the engagement position is restricted). When the right end portion is lowered below the communication portion 42, the tip of the engagement portion 58 is transferred to and contacted with the side surface of the door-side lock claw 2 facing the communication portion 42, and is held in the non-engagement position by the door-side lock claw 2. (Rotation to the engagement position is restricted).

扉側ロック爪２の先端が、回転レバー２１の係合部５８を越えてさらに扉側ロック爪挿入室４１の底部側に挿入されると、扉側ロック爪２は、その先端で、初期位置にある押圧レバー２９の操作部７２を押圧し、押圧レバー２９を圧縮コイルバネ３０の付勢力に抗して押し下げ、その押圧レバー２９で板バネ３１の他片の先端部（自由端部）を下方に押し下げ、その板バネ３１の他片を下方に撓み変形させ、その板バネ３１の他片を第１スイッチ２８の押しボタン部に当接させる。   When the front end of the door side lock claw 2 is inserted into the bottom side of the door side lock claw insertion chamber 41 beyond the engaging portion 58 of the rotation lever 21, the door side lock claw 2 is moved to the initial position. The operating portion 72 of the pressing lever 29 is pressed, the pressing lever 29 is pressed down against the urging force of the compression coil spring 30, and the pressing lever 29 lowers the tip (free end) of the other piece of the leaf spring 31. The other piece of the leaf spring 31 is bent downward and deformed, and the other piece of the leaf spring 31 is brought into contact with the push button portion of the first switch 28.

そして、図８に示すように、扉側ロック爪２の先端が、扉側ロック爪挿入室４１の底部側にある隔壁５に突き当たるぐらいに挿入されると、扉側ロック爪２の係合孔１が連通部４２に対向し、その連通部４２を開くため、回転レバー２１の係合位置への回転規制がなくなり、回転レバー２１が、トーションバネ２２の付勢力で係合方向に回転する。これにより、回転レバー２１の係合部５８が、連通部４２から扉側ロック爪２の係合孔１に嵌込んだ状態で扉側ロック爪挿入室４１内に突出すると共に、回転レバー２１の係合部５８の前後両側にある他端側左端部がストッパー４６に付き当たり、回転レバー２１が図７及び図８に示す係合位置に保持され、扉側ロック爪２と自動係合する。すなわち、扉が閉じた状態でロックされる。   As shown in FIG. 8, when the end of the door side lock claw 2 is inserted so as to abut against the partition wall 5 on the bottom side of the door side lock claw insertion chamber 41, the engagement hole of the door side lock claw 2 is inserted. Since 1 faces the communication portion 42 and opens the communication portion 42, the rotation restriction to the engagement position of the rotation lever 21 is eliminated, and the rotation lever 21 rotates in the engagement direction by the urging force of the torsion spring 22. As a result, the engaging portion 58 of the rotating lever 21 protrudes into the door-side lock claw insertion chamber 41 in a state where the engaging portion 58 is fitted into the engaging hole 1 of the door-side lock claw 2 from the communication portion 42, and The left end of the other end on both the front and rear sides of the engaging portion 58 comes into contact with the stopper 46, and the rotary lever 21 is held at the engaging position shown in FIGS. 7 and 8 and automatically engages with the door-side lock claw 2. That is, the door is locked with the door closed.

また、扉が閉じた状態でロックされたときには、蓋体８４は、扉側ロック爪２と扉側ロック爪挿入室４１の右側の側壁６の間の全開位置に回転し、蓋体８４の右端部上面を扉側ロック爪２の側面に当接した状態で、全開位置に保持され、開口部３を全開している。   When the door is locked in a closed state, the lid 84 rotates to the fully open position between the door side lock claw 2 and the right side wall 6 of the door side lock claw insertion chamber 41, and the right end of the lid 84 In a state where the upper surface of the part is in contact with the side surface of the door-side lock claw 2, the opening 3 is fully opened.

また、このように扉が閉じた状態でロックされたときに、扉側ロック爪２の先端で押圧レバー２９が最も押し下げられ、その押圧レバー２９で板バネ３１の他片が最も下方に撓み変形し、その板バネ３１の他片で第１スイッチ２８の押しボタン部が押し下げれて、第１スイッチ２８をオンにし、その第１スイッチ２８のオン動作でロック状態（扉側ロック爪２の完全挿入）を検知する。   Further, when the door is locked in the closed state as described above, the pressing lever 29 is pushed down most at the tip of the door-side locking claw 2, and the other piece of the leaf spring 31 is bent downward and deformed by the pressing lever 29. Then, the push button portion of the first switch 28 is pushed down by the other piece of the leaf spring 31 and the first switch 28 is turned on. When the first switch 28 is turned on, the lock state is established (the door side locking claw 2 is completely closed). ) Is detected.

さらに、第１スイッチ２８のオン動作出力信号（ロック状態検知信号）に基づき、ソレノイド３３の１次コイルへのパルス通電でソレノイド３３が駆動される。   Further, based on the ON operation output signal (lock state detection signal) of the first switch 28, the solenoid 33 is driven by applying a pulse to the primary coil of the solenoid 33.

ソレノイド３３が駆動されると、初期位置にある可動鉄心７４が圧縮コイルバネ７８の付勢力に抗して吸引方向に摺動し、それと一体的に、初期位置にあるスライドレバー３６が、圧縮コイルバネ３７を圧縮し、そのバネ力を高めながら、圧縮コイルバネ７８の付勢力に抗してスライド移動し、可動鉄心７４及びスライドレバー３６が図９に示す吸着位置に保持される。   When the solenoid 33 is driven, the movable iron core 74 in the initial position slides in the suction direction against the urging force of the compression coil spring 78, and the slide lever 36 in the initial position integrally with the compression coil spring 37. 9, while the spring force is increased, the movable iron core 74 and the slide lever 36 are held at the suction positions shown in FIG. 9.

その際、スライドレバー３６は、その押圧部８０が、初期位置にある可動アーム２４のストッパーピン６４を傾斜部８１を介して右側に押圧し、傾斜部８１が押圧部８０の押圧方向を上方向に変換するため、可動アーム２４の左端部が押し上げられ、可動アーム２４が板バネ２５の付勢力に抗してシーソー運動し、可動アーム２４の右端部にある係合部６７が初期位置から図９に示す係合位置に下降操作される。これにより、可動アーム２４の係合部６７が回転レバー２１と係合し、回転レバー２１の非係合位置方向への回転動作を阻止する。すなわち、扉のロック状態が保持される。   At that time, the pressing portion 80 of the slide lever 36 presses the stopper pin 64 of the movable arm 24 at the initial position to the right side through the inclined portion 81, and the inclined portion 81 moves the pressing direction of the pressing portion 80 upward. Therefore, the left end portion of the movable arm 24 is pushed up, the seepage motion of the movable arm 24 resists the urging force of the leaf spring 25, and the engaging portion 67 at the right end portion of the movable arm 24 is viewed from the initial position. 9 is lowered to the engagement position shown in FIG. As a result, the engaging portion 67 of the movable arm 24 engages with the rotating lever 21 and prevents the rotating lever 21 from rotating in the direction of the non-engaging position. That is, the locked state of the door is maintained.

また、このように扉のロック状態が保持されたときに、スライドレバー３６が圧縮コイルバネ３７を最も圧縮し、そのバネ力が第２スイッチ３５の押しボタン部に常時付勢されている復帰力よりも強くなり、第２スイッチ３５の押しボタン部が押し込まれ、第２スイッチ３５をオンにし、その第２スイッチ３５のオン動作でロック保持状態（扉の完全ロック）を検知する。   Further, when the door is locked as described above, the slide lever 36 compresses the compression coil spring 37 most, and the spring force is based on the return force that is always urged by the push button portion of the second switch 35. The push button portion of the second switch 35 is pushed in, the second switch 35 is turned on, and the lock holding state (the door is completely locked) is detected by the on operation of the second switch 35.

そして、第２スイッチ３５のオン動作出力信号（扉の完全ロック信号）に基づき、洗濯機、乾燥機、食器洗い機等を動作させるものである。   Based on the ON operation output signal (door complete lock signal) of the second switch 35, the washing machine, the dryer, the dishwasher and the like are operated.

なお、強制解除ボタン２６は、可動アーム２４の左端部の押し上げに連動して押し上げられて、ロック強制解除用の操作口１９内に押し込まれている。   The forcible release button 26 is pushed up in conjunction with the push-up of the left end portion of the movable arm 24 and pushed into the lock forcibly releasing operation port 19.

一方、図７乃至図９に示すロック状態（扉は閉じている）で、例えば洗濯機、乾燥機、食器洗い機等の機器本体又は扉に設けた扉開放操作部の操作をスイッチで検知すると、そのスイッチの動作出力（扉の開放信号）に基づき、ソレノイド３３の２次コイル（復帰コイル）へのパルス通電でソレノイド３３が復帰駆動される。   On the other hand, in the locked state shown in FIGS. 7 to 9 (the door is closed), for example, when the operation of the door opening operation unit provided on the apparatus body or door such as a washing machine, dryer, dishwasher, etc. is detected with a switch, Based on the operation output of the switch (door opening signal), the solenoid 33 is driven to return by applying a pulse to the secondary coil (return coil) of the solenoid 33.

ソレノイド３３が復帰駆動されると、可動鉄心７４及びスライドレバー３６が圧縮コイルバネ７８の付勢力で図４及び図６に示す初期位置に復帰し、そのスライドレバー３６の復帰動作で圧縮コイルバネ３７が伸長し、そのバネ力が第２スイッチ３５の押しボタン部の復帰力よりも弱くなり、第２スイッチ３５が図４に示す初期状態（オフ状態）に復帰すると共に、スライドレバー３６の押圧部８０による可動アーム２４の左端部の押圧がなくなり、可動アーム２４の右端部が板バネ２５の付勢力で押し上げられ、可動アーム２４がシーソー運動し、可動アーム２４の係合部６７が係合位置から図６に示す初期位置に復帰する。これにより、回転レバー２１が非係合位置方向に回転動作できるようになる。すなわち、扉のロック状態保持が解除される。   When the solenoid 33 is driven to return, the movable iron core 74 and the slide lever 36 return to the initial positions shown in FIGS. 4 and 6 by the urging force of the compression coil spring 78, and the compression coil spring 37 extends by the return operation of the slide lever 36. Then, the spring force becomes weaker than the return force of the push button portion of the second switch 35, and the second switch 35 returns to the initial state (off state) shown in FIG. The left end portion of the movable arm 24 is no longer pressed, the right end portion of the movable arm 24 is pushed up by the urging force of the leaf spring 25, the movable arm 24 performs a seesaw motion, and the engaging portion 67 of the movable arm 24 is viewed from the engaged position. The initial position shown in FIG. Thereby, the rotation lever 21 can be rotated in the non-engagement position direction. That is, the locked state of the door is released.

なお、強制解除ボタン２６は、可動アーム２４の左端部の下降（右端部の押し上げ）に連動して下降し、強制解除ボタン２６の上部がロック強制解除用の操作口１９の最奥部まで下降している。   The forcible release button 26 descends in conjunction with the lowering of the left end of the movable arm 24 (pushing up the right end), and the upper part of the forcible release button 26 descends to the innermost part of the operation port 19 for forcibly releasing the lock. is doing.

また、当該扉ロック装置の外部ロック解除機構による扉開放操作部と解除ピン２３との連結で、扉のロック状態保持を解除したときに解除ピン２３が後側に引張り操作される。   Further, when the door lock operation is released by connecting the door opening operation portion and the release pin 23 by the external lock release mechanism of the door lock device, the release pin 23 is pulled backward.

解除ピン２３が後側に引張り操作されると、係合位置にある回転レバー２１がトーションバネ２２の付勢力に抗して図９に示す非係合方向に回転し、初期位置（非係合位置）に復帰し、回転レバー２１の係合部５８が扉側ロック爪２の係合孔１から抜かれて、連通部４２から扉側ロック爪挿入室４１外に抜かれ、回転レバー２１の係合部５８と扉側ロック爪２との係合が解除される。すなわち、扉の閉じた状態でのロックが解除される。これにより、扉側ロック爪２が外箱４の外部に抜去可能となり、扉を開くことができるようになる。   When the release pin 23 is pulled rearward, the rotary lever 21 in the engaged position rotates in the non-engagement direction shown in FIG. 9 against the urging force of the torsion spring 22, and the initial position (non-engagement). The engagement portion 58 of the rotary lever 21 is removed from the engagement hole 1 of the door-side lock claw 2 and is extracted from the communication portion 42 to the outside of the door-side lock claw insertion chamber 41 to engage the rotation lever 21. The engagement between the portion 58 and the door-side lock claw 2 is released. That is, the lock with the door closed is released. Thereby, the door side lock claw 2 can be removed to the outside of the outer box 4, and the door can be opened.

扉の閉じた状態でのロックが解除され、扉が開かれて、扉側ロック爪２が外箱４の外部に抜かれると、扉側ロック爪２による押圧レバー２９の操作部７２の押圧がなくなるから、図５に示すように、押圧レバー２９が圧縮コイルバネ３０の付勢力で初期位置に復帰し、それに連動して板バネ３１が自身の弾性で初期位置に復帰し、第１スイッチ２８が初期状態（オフ状態）に復帰する。   When the door is unlocked, the door is opened, and the door-side lock claw 2 is pulled out of the outer box 4, the door-side lock claw 2 presses the operation portion 72 of the pressing lever 29. Therefore, as shown in FIG. 5, the pressing lever 29 returns to the initial position by the urging force of the compression coil spring 30, and in conjunction with this, the leaf spring 31 returns to the initial position by its own elasticity, and the first switch 28 is Return to the initial state (off state).

また、扉側ロック爪２が外箱４の外部に抜かれるとき、蓋体８４は、その右端面を扉側ロック爪２の先端に当接した状態で、扉側ロック爪２の抜去動作に追従してダブルトーションバネ８７の付勢力で閉方向に回転し、扉側ロック爪２の先端が開口部３を通過するのに伴って図３及び図５に示す閉位置に復帰する。また、回転レバー２１は、その係合部５８の先端がトーションバネ２２の付勢力で閉位置にある蓋体８４の当接部８８に押し付けられて、そのまま図３及び図５に示す初期位置（非係合位置）に保持される。   Further, when the door side lock claw 2 is pulled out of the outer box 4, the lid 84 performs the removal operation of the door side lock claw 2 with its right end face in contact with the tip of the door side lock claw 2. Following this, it rotates in the closing direction by the urging force of the double torsion spring 87, and returns to the closed position shown in FIGS. 3 and 5 as the tip of the door-side lock claw 2 passes through the opening 3. Further, the rotary lever 21 has its engaging portion 58 tip pressed against the abutting portion 88 of the lid 84 in the closed position by the urging force of the torsion spring 22, and the initial position shown in FIGS. Held in the disengaged position).

なお、ソレノイド３３の可動鉄心７４が吸着位置から復帰できないという故障が発生した場合、ロック強制解除用の操作口１９から強制解除ボタン２６を押し下げることによって、可動アーム２４の左端部にあるストッパーピン６４を押し下げて、そのストッパーピン６４でスライドレバー３６の押圧部８０を傾斜部８１を介して左側に押圧し、スライドレバー３６と一体的に可動鉄心７４を初期位置に戻すことができる。すなわち、扉のロック状態保持を強制的に解除することができ、扉の閉じた状態でのロックを解除し、扉を開くことができるようになる。   When a failure occurs in which the movable iron core 74 of the solenoid 33 cannot be returned from the suction position, the stopper pin 64 at the left end of the movable arm 24 is depressed by depressing the forcible release button 26 from the operation port 19 for forcibly releasing the lock. And the stopper pin 64 presses the pressing portion 80 of the slide lever 36 to the left side through the inclined portion 81, so that the movable iron core 74 can be returned to the initial position integrally with the slide lever 36. In other words, the locked state of the door can be forcibly released, the door can be unlocked and the door can be opened.
