Just before the cleaning tank 2 is completely accommodated in the main body 1 of the cleaning machine, the lock plate 13 provided with the claw 16 of the lock piece 13 protruding from the opening 17 provided on the side wall of the door 9 is provided in the main body 1 of the cleaning machine. 15 abuts.
この状態で洗浄槽２をさらに押し込むと、ロック片１３がロック板１５によって軸１４
を支点に回転させられ、一時的に爪部１６が開口部１７の内部に変位して収納され、洗浄槽２が洗浄機本体１内に完全に収納される。洗浄槽２が完全に収納されると、爪部１６がロック板１５を乗り越えて後方に位置するため、爪部１６は、バネ１８の反発力によって再び開口部１７より突出した状態に戻る。この状態において爪部１６とロック板１５は、洗浄槽２を前方に引張る方向に対してくさび状に引っ掛かる形状となっているため、洗浄槽２は洗浄機本体１にロックされた状態で保持される（図２（ａ）参照）。
When the cleaning tank 2 is further pushed in this state, the lock piece 13 is moved by the lock plate 15 to the shaft 14.
The claw portion 16 is temporarily displaced and accommodated in the opening portion 17, and the cleaning tank 2 is completely accommodated in the cleaning machine main body 1. When the cleaning tank 2 is completely stored, the claw portion 16 moves over the lock plate 15 and is positioned rearward, so that the claw portion 16 returns to the state of projecting from the opening portion 17 again by the repulsive force of the spring 18. In this state, the claw portion 16 and the lock plate 15 have a wedge-like shape with respect to the direction in which the cleaning tank 2 is pulled forward, so that the cleaning tank 2 is held in a state locked to the cleaning machine body 1. (See FIG. 2 (a)).
上述したように、食器類３を洗浄槽２内にセットした後に洗浄槽２が洗浄機本体１内に完全に収納され、洗浄機本体１と洗浄槽２がロックされた状態となると、バネ１８の反発によって再び開口部１７より爪部１６が突出した状態に戻るため、取っ手レバー２２は回動軸２３を介し、下方向へ最も下がった位置にて保持される（図３（ｂ）参照）。この状態で取っ手レバー２２を回動軸２３の長手方向左側（空間２７の方向）に移動させ、凸部２４と凹部２６を嵌合させることで、取っ手レバー２２と回動軸２３の回転をロックし、ロック片１３の爪部１６が開口部１７の内部に収納されるのを防止する。 As described above, after the tableware 3 is set in the cleaning tank 2, the cleaning tank 2 is completely stored in the cleaning machine main body 1, and the spring 18 is brought into a locked state. The handle lever 22 is held at the position where the handle lever 22 is lowered downward via the rotating shaft 23 (see FIG. 3B). . In this state, the handle lever 22 is moved to the left in the longitudinal direction of the rotation shaft 23 (in the direction of the space 27), and the convex portion 24 and the concave portion 26 are fitted to lock the rotation of the handle lever 22 and the rotational shaft 23. Thus, the claw portion 16 of the lock piece 13 is prevented from being housed inside the opening portion 17.
また、運転途中や運転終了後に食器類３を取り出す場合は、逆に、取っ手レバー２２を回動軸２３の長手方向右側に移動させて凸部２４と凹部２６の嵌合を解除した後、取っ手２５の上面内側に当接もしくはそれに近い位置まで取っ手レバー２２を上方に持ち上げることで（図３（ａ）参照）、爪部１６が開口部１７の内部に変位して収納され、洗浄機本体１と洗浄槽２のロック状態が解除される。これにより取っ手レバー２２を上方に持ち上げている間は洗浄機本体１に対し、洗浄槽２が出し入れ可能な状態となる。 On the other hand, when the tableware 3 is taken out during or after the operation, the handle lever 22 is moved to the right in the longitudinal direction of the rotating shaft 23 to release the fitting of the convex portion 24 and the concave portion 26, and then the handle. When the handle lever 22 is lifted up to a position close to or close to the inner surface of the upper surface 25 (see FIG. 3A), the claw portion 16 is displaced and accommodated inside the opening portion 17, and the washing machine body 1 And the lock | rock state of the washing tank 2 is cancelled | released. As a result, while the handle lever 22 is lifted upward, the cleaning tank 2 can be taken in and out of the cleaning machine body 1.
以上のように、取っ手レバー２２の移動位置に応じて、取っ手レバー２２と回動軸２３の回転動作を規制または規制解除する構成としたことにより、ロック機構部品を新たに追加せずに必要な時に取っ手レバー２２の回動を規制して、子供等が不用意にロック状態を解除するのを防止することができる。 As described above, the rotation operation of the handle lever 22 and the rotation shaft 23 is restricted or released according to the movement position of the handle lever 22, so that it is necessary without newly adding a lock mechanism component. Occasionally, the rotation of the handle lever 22 can be restricted to prevent a child or the like from inadvertently releasing the locked state.
また、取っ手レバー２２のロック位置を、取っ手レバー２２が最も下方向へ下がる位置にすることで、取っ手２５内の手掛け部が浅くなり手を掛けにくくなるため、無理に力を加えてロック部分が破損するのを防止することができる。 In addition, by setting the handle lever 22 to the locked position where the handle lever 22 is lowered most downward, the handle portion in the handle 25 becomes shallow and it is difficult to place a hand. It can be prevented from being damaged.
以上のように、本発明にかかる食器洗い機は、取っ手レバーを回動軸の軸方向に移動可能に支持し、取っ手レバーの移動位置に応じて取っ手レバーと回動軸の回転動作を規制可能とすることで、必要な時に取っ手レバーの回動を規制して子供等が不用意にロック状態を解除するのを防止することが可能となるので、洗浄槽を引き出して食器類の出し入れを行うビルトイン型食器洗い機等として有用である。 As described above, the dishwasher according to the present invention supports the handle lever so as to be movable in the axial direction of the rotation shaft, and can regulate the rotation operation of the handle lever and the rotation shaft according to the movement position of the handle lever. This makes it possible to prevent the child from inadvertently releasing the locked state by restricting the rotation of the handle lever when necessary. It is useful as a type dishwasher.
