When the cleaning tank is located in the cleaning tank-inner lid interlocking storage range, which is a storage range from the storage position where a predetermined amount is pulled out to the final storage position, the cleaning tank is stored and withdrawn when the cleaning tank is stored and withdrawn. The upper lid is opened and closed by moving the inner lid in the storage direction and the drawer direction with the same movement amount as the movement direction of the tank in the storage direction and the drawer direction, and the cleaning tank is the cleaning tank-inner lid The left and right protrusions and the cleaning tank are not in contact with each other when the storage position is outside the interlocked storage range.

本発明（請求項１）は、直方体を構成する６面から前記前面開口部となる１面を除いた、左右の両側面、天面、底面、および、後面の５面によって構成され、直方体の箱状に形成された洗浄機本体の筐体における筐体の後部の剛性が高く変形が生じにくくなっていることによる特性を有効に利用するものであり、洗浄槽後部と洗浄機本体（筐体）後部との相対的な位置のずれは生じにくくなっているから、洗浄機の後部においては、洗浄機本体（筐体）に対する内蓋の後端の左右方向へのずれを規制するだけの簡単な構成で、洗浄槽と内蓋との相対的なずれも生じにくいようにできる。そして、洗浄機本体（筐体）は前面が開口しているから、横方向の外力に対するその剛性は小さいものであり、輸送時や設置時の取扱不備などによって洗浄機本体（筐体）の前部は左右方向の歪みが生じるおそれがあるものであるから、洗浄槽と洗浄機本体（筐体）との相対的な位置のずれは生じ易いものであることに配慮し、洗浄機前部においては、洗浄機本体（筐体）に対する内蓋の前端の左右方向へのずれを規制しても、洗浄槽と内蓋との横方向の相対的なずれは防止し難いものであるから、内蓋の前端部と洗浄槽との相互間の左右方向の位置を規制する蓋前端横方向規制部により洗浄槽と内蓋との横方向の相対的なずれが生じないようにすることができる。 The present invention (Claim 1) is composed of five surfaces including right and left side surfaces, a top surface, a bottom surface, and a rear surface, excluding one surface serving as the front opening from six surfaces constituting a rectangular parallelepiped. It effectively utilizes the characteristics of the rear case of the washer body formed in a box shape because the rigidity of the rear part of the case is high and hardly deformed. ) Since the relative position with the rear part is less likely to shift, the rear part of the cleaning machine is simple enough to regulate the lateral shift of the rear end of the inner lid with respect to the cleaning machine body (housing). With this configuration, it is possible to prevent relative displacement between the cleaning tank and the inner lid. And since the front of the washer main body (housing) is open, its rigidity against the lateral external force is small, and the front of the washer main body (housing) is inadequate due to inadequate handling during transportation or installation. Considering that the relative position between the washing tank and the washing machine main body (housing) is likely to occur, the front part of the washing machine Since it is difficult to prevent the horizontal displacement between the cleaning tank and the inner lid even if the displacement of the front end of the inner lid with respect to the main body (housing) in the horizontal direction is restricted, It is possible to prevent a relative displacement in the lateral direction between the cleaning tank and the inner lid from occurring due to the lid front end lateral regulating part that regulates the left-right position between the front end of the lid and the washing tank.

つまり、洗浄機本体（筐体）の後部と前部の剛性に応じた簡単な構成で、内蓋の前端部から後端部に亘る全域で内蓋と洗浄槽との相互間の左右方向の位置のずれを規制でき、洗浄用湯水の洗浄槽からの漏出を防止することができる。 In other words, with a simple configuration corresponding to the rigidity of the rear and front of the cleaning machine main body (housing), the left and right directions between the inner lid and the cleaning tank in the entire region from the front end to the rear end of the inner lid. The displacement of the position can be regulated, and leakage from the washing tank for washing hot water can be prevented.

また、本発明（請求項１）によれば、内蓋の前端部の左右両側から左右の突起を垂下形成しておき、内蓋が洗浄槽の上面開口部を封止するときに、この左右の突起の間に洗浄槽の上縁の外周縁が嵌入するようにするだけの簡単な構成で、内蓋の前端部から後端部に亘る全域で内蓋と洗浄槽との相互間の左右方向の位置のずれを規制でき、洗浄用湯水の洗浄槽からの漏出を防止することができる。 Further, according to the present invention (Claim 1 ), the left and right protrusions are suspended from the left and right sides of the front end portion of the inner lid, and when the inner lid seals the upper surface opening of the cleaning tank, The outer edge of the upper edge of the cleaning tank is simply inserted between the projections of the inner lid, and the left and right sides of the inner lid and the cleaning tank are crossed over the entire area from the front end to the rear end of the inner lid. The displacement of the direction can be restricted, and leakage from the washing tank for washing hot water can be prevented.

また、請求項１の発明によれば、帯状の金属片を前記内蓋の前端部における左右両側に止着するだけの簡単な構成で、内蓋の前端部から後端部に亘る全域で内蓋と洗浄槽との相互間の左右方向の位置のずれを規制でき、洗浄用湯水の洗浄槽からの漏出を防止することができる。また、左右の突起には外側に先広がりとなる傾斜部を設けてあるから、内蓋の前端部における洗浄槽との左右方向のずれが大きいときにも適切に内蓋と洗浄槽との相互間の左右方向の位置のずれを規制でき、洗浄用湯水の洗浄槽からの漏出を防止することができる。 According to the first aspect of the present invention, the belt-like metal piece is simply configured to be fixed to both the left and right sides of the front end portion of the inner lid, and the inner cover is formed over the entire region from the front end portion to the rear end portion of the inner lid. It is possible to regulate the displacement of the position between the lid and the cleaning tank in the left-right direction, and to prevent leakage of cleaning water from the cleaning tank. In addition, since the left and right protrusions are provided with inclined portions that are widened outwardly, the inner lid and the cleaning tank can be properly connected to each other even when there is a large lateral shift from the cleaning tank at the front end of the inner lid. Therefore, it is possible to prevent the displacement of the position in the left-right direction between them, and to prevent leakage of cleaning water from the cleaning tank.

また、請求項１の発明によれば、帯状の金属片には、左右の前記帯状の金属片の間に向けた方向に突出する形態で、上下方向に伸びる帯状の滑らかな凸部を形成してあるから、左右の前記帯状の金属片の間に洗浄槽の上縁の外周縁が嵌入する際に、洗浄槽の上縁の外周縁が帯状の金属片（左右の突起）により損傷することが防止できる。 According to the invention of claim 1 , the belt-like metal piece is formed with a belt-like smooth convex portion extending in the vertical direction so as to protrude in a direction toward the space between the left and right belt-like metal pieces. Therefore, when the outer peripheral edge of the upper edge of the cleaning tank is inserted between the left and right strip-shaped metal pieces, the outer peripheral edge of the upper edge of the cleaning tank is damaged by the strip-shaped metal pieces (left and right protrusions). Can be prevented.

また、請求項２の発明によれば、請求項１の発明による効果に加えて、前後方向（収納または引き出し方向に沿った方向）の摺動に起因する洗浄槽の磨耗や蓋前端横方向規制部Ｆの変形が防止できるものとなり、食器洗浄機の耐久性を良好なものとすることができる。 According to the second aspect of the invention, in addition to the effect of the first aspect of the invention, the wear of the cleaning tank and the lid front end lateral direction restriction caused by sliding in the front-rear direction (the direction along the storing or pulling-out direction). The deformation of the part F can be prevented, and the durability of the dishwasher can be improved.

内蓋１０の左右の各側部には、カムフォロアとして機能する前後一対のカムピン３７（図３）がそれぞれ外側に向けて突出するように設けられている。また、内蓋１０の上部と洗浄機本体１の前端部との間には、内蓋１０を洗浄機本体１の前面開口部３側に向けて付勢するコイルスプリングからなる蓋用スプリング３８が介装されている。 A pair of front and rear cam pins 37 (FIG. 3) functioning as cam followers are provided on the left and right sides of the inner lid 10 so as to protrude outward. Further, between the upper portion of the inner lid 10 and the front end portion of the cleaner main body 1, a lid spring 38 made of a coil spring that biases the inner lid 10 toward the front opening 3 of the cleaner main body 1 is provided. It is intervened.

また、洗浄機本体１の側面の内側の上部左右の側端には、図１０に示すように、前後一対の保持舌片２３が内蓋１０の各カムピン３７に個別に対応するように洗浄機本体１と一体的に設けられている。そして、各前後一対の保持舌片２３間には、クランプ部材２６が上下方向（図５において、符号Ｃで示す方向）に移動可能な状態で嵌入されている。 Further, as shown in FIG. 10, the pair of front and rear holding tongue pieces 23 are individually attached to the respective cam pins 37 of the inner lid 10 at the upper left and right side edges inside the side surface of the cleaner body 1. It is provided integrally with the main body 1. A clamp member 26 is fitted between the pair of front and rear holding tongue pieces 23 so as to be movable in the vertical direction (the direction indicated by the symbol C in FIG. 5).

各クランプ部材２６は、合成樹脂や金属製の成形品からなり、その上部には、内蓋１０の前述のカムピン３７がそれぞれ嵌入するカム溝２２が、また、カム溝２２の両端部の外側には各保持舌片２３の上縁に当接して位置決め保持される保持片２４が形成されている。さらに、クランプ部材２６の下部には、洗浄槽２の後述の受け止め面３５（図３(イ)など）が当接することで当該クランプ部材２６の上方向への移動を規制するための当接部２５が形成されている。 Each clamp member 26 is made of a molded product made of synthetic resin or metal, and the upper portion thereof has cam grooves 22 into which the above-described cam pins 37 of the inner lid 10 are fitted, and the outer sides of both ends of the cam grooves 22. A holding piece 24 is formed which is positioned and held in contact with the upper edge of each holding tongue piece 23. Further, a receiving part 35 (described later with reference to FIG. 3A, etc.) of the cleaning tank 2 abuts on the lower part of the clamp member 26, thereby restricting the upward movement of the clamp member 26. 25 is formed.

前記カム溝２２は図３に示すように、中心線Ｌを中心として左右対称形に略Ｖ字状に形成されており、洗浄槽２が洗浄機本体１内に収納されたときにはカムピン３７はカム溝２２の最下方位置に、洗浄槽２が洗浄機本体１から引き出されたときにはカムピン３７はカム溝２２の最上方位置にそれぞれ移行する。 As shown in FIG. 3, the cam groove 22 is formed in a substantially V shape symmetrically about the center line L. When the cleaning tank 2 is stored in the cleaning machine main body 1, the cam pin 37 is a cam. When the washing tub 2 is pulled out from the washing machine main body 1 at the lowermost position of the groove 22, the cam pin 37 moves to the uppermost position of the cam groove 22.

前記洗浄槽２は、その上面開口部４の外周に沿った各辺に外方に張り出したフランジ部３２（図３(イ)，図５(イ)）が形成され、その内の左右の各フランジ部３２からは下方へ向けて突出する状態で受け止め面３５（図３(イ)，図５(イ)）が形成され、各受け止め面３５の下縁がクランプ部材２６の当接部２５に対向している。 The cleaning tank 2 is formed with flange portions 32 (FIGS. 3 (A) and 5 (A)) projecting outwardly on each side along the outer periphery of the upper surface opening 4, and each of the left and right sides thereof Receiving surfaces 35 (FIGS. 3 (A) and 5 (A)) are formed in a state of projecting downward from the flange portion 32, and the lower edge of each receiving surface 35 is formed on the contact portion 25 of the clamp member 26. Opposite.

洗浄機本体１の内側後方の上部左右の位置には、内蓋開閉操作具としての一対の案内レバー１１（図３，図５）がそれぞれ配置されている。各案内レバー１１は、洗浄機本体１に固定された取付固定部１２（図３、図４、図５、図７等）、揺動支承軸３９、プッシュレバー１３、および案内ピン１４を備えている。そして、プッシュレバー１３の基端側は、取付固定部１２に設けられた揺動支承軸３９を軸心として揺動自在に取り付けられ、また、先端側には上下方向に沿って延びる円筒状の案内ピン１４が設けられている。 A pair of guide levers 11 (FIGS. 3 and 5) serving as an inner lid opening / closing operation tool are respectively arranged at the upper left and right positions on the inner rear side of the cleaning machine body 1. Each guide lever 11 includes an attachment fixing portion 12 (FIGS. 3, 4, 5, 7, etc.) fixed to the cleaning machine body 1, a swing support shaft 39, a push lever 13, and a guide pin 14. Yes. The proximal end side of the push lever 13 is pivotably mounted about a swinging support shaft 39 provided in the mounting and fixing portion 12, and a cylindrical shape extending in the vertical direction on the distal end side. Guide pins 14 are provided.

一方、内蓋１０の後端部の左右には、洗浄槽２の移動方向と直交する方向に延びる長穴１６（図３）が形成されており、各長穴１６にプッシュレバー１３の先端部の案内ピン１４が常時嵌入されている。これにより、案内ピン１４が長穴１６に沿って摺動する摺動可能範囲内でプッシュレバー１３が揺動し得るので、これに応じて内蓋１０もプッシュレバー１３の揺動可能範囲内で前後方向（図３(ロ)の左右方向）に沿って移動するように構成されている。そして、前述のように、内蓋１０の左右にはカムピン３７が固定されているので、内蓋１０の前後の移動に伴ってカムピン３７は、クランプ部材２６のカム溝２２に沿って摺動する。 On the other hand, elongated holes 16 (FIG. 3) extending in the direction orthogonal to the moving direction of the cleaning tank 2 are formed on the left and right of the rear end portion of the inner lid 10, and the distal end portion of the push lever 13 is formed in each elongated hole 16. The guide pin 14 is always inserted. As a result, the push lever 13 can swing within a slidable range in which the guide pin 14 slides along the elongated hole 16, and accordingly, the inner lid 10 also falls within the swayable range of the push lever 13. It is configured to move along the front-rear direction (the left-right direction in FIG. 3B). Since the cam pins 37 are fixed to the left and right of the inner lid 10 as described above, the cam pins 37 slide along the cam grooves 22 of the clamp member 26 as the inner lid 10 moves back and forth. .

また、洗浄槽２の後方端の上部左右には、図９に示すように、洗浄槽溝１５が案内レバー１１に個別に対応して設けられている。この洗浄槽溝１５は、例えば図３(ロ)に示すように、嵌合手前側当接部１７と奥側当接部１８とで囲まれた状態で形成されており、嵌合手前側当接部１７は洗浄槽２の側面まで延び、また奥側当接部１８は途中で後方側に後退するようにそれぞれ形成されている。そして、各洗浄槽溝１５は、プッシュレバー１３の揺動によってプッシュレバー１３の先端の案内ピン１４と係脱するように構成されている。 Further, as shown in FIG. 9, cleaning tank grooves 15 are provided individually corresponding to the guide levers 11 on the upper left and right of the rear end of the cleaning tank 2. For example, as shown in FIG. 3B, the cleaning tank groove 15 is formed in a state surrounded by a front-side contact portion 17 and a rear-side contact portion 18, The contact portion 17 extends to the side surface of the cleaning tank 2, and the back contact portion 18 is formed so as to recede backward in the middle. And each washing tank groove | channel 15 is comprised so that engagement / disengagement with the guide pin 14 of the front-end | tip of the push lever 13 by rocking | fluctuation of the push lever 13 may be carried out.

また、洗浄機本体１内の後方箇所には、洗浄槽２を収納方向および引き出し方向に移動させる際にその移動力を補助するための左右一対のトグル機構２７が設けられている。（図３、図４）
各トグル機構２７は、洗浄槽２の後端部に係合用ピン３６が配設される一方、洗浄機本体１の後端部には、略Ｌ字状のレバー２９が枢支ピン３１によって揺動自在に設けられ、このレバー２９の枢支ピン３１を挟む一端側には上記の係合用ピン３６に係合する係合用切欠き２８が形成され、他端側は洗浄機本体１に一端が固定されたコイルスプリング３０（図３(イ)，図５(イ)）の他端が取り付けられて構成されている。これにより、レバー２９に対するコイルスプリング３０の付勢力（回動作用方向）が、図５(イ)に示す設定切換位置Ｄを境として時計方向と反時計方向とに切り換わるように構成されている。 In addition, a pair of left and right toggle mechanisms 27 for assisting the moving force when the cleaning tank 2 is moved in the storing direction and the pulling-out direction are provided at a rear portion in the cleaning machine main body 1. (Fig. 3, Fig. 4)
Each toggle mechanism 27 is provided with an engaging pin 36 at the rear end portion of the cleaning tank 2, while a substantially L-shaped lever 29 is rocked by a pivot pin 31 at the rear end portion of the cleaning machine body 1. An engagement notch 28 that engages with the engagement pin 36 is formed on one end side of the lever 29 that sandwiches the pivot pin 31, and the other end has one end on the cleaning machine body 1. The other end of the fixed coil spring 30 (FIGS. 3 (A) and 5 (A)) is attached. As a result, the biasing force (rotation direction) of the coil spring 30 with respect to the lever 29 is configured to switch between the clockwise direction and the counterclockwise direction at the setting switching position D shown in FIG. .

また、この実施例では、洗浄機本体１内の後部側にロック機構４０が設けられている（図６）。このロック機構４０は、洗浄運転時には洗浄槽２が洗浄機本体１内に収納されて引き出すことができない状態であるロック状態と、洗浄運転が行われていない状態では洗浄槽２を洗浄機本体１内から自由に引き出すことができる状態であるロック解除状態とを実現することができるように構成されているものであるが、本書では詳述しない。 In this embodiment, a lock mechanism 40 is provided on the rear side in the cleaning machine main body 1 (FIG. 6). The lock mechanism 40 is configured such that the cleaning tank 2 is housed in the cleaning machine main body 1 during the cleaning operation and cannot be pulled out, and the cleaning tank 2 is connected to the cleaning machine main body 1 when the cleaning operation is not performed. Although it is configured to be able to realize an unlocked state in which it can be pulled out freely from the inside, it will not be described in detail in this document.

また、図１３(イ)，(ロ)に示すように、洗浄槽２の後端部には取付板５２が設けられ、この取付板５２に洗浄槽位置センサ５３が固定されるとともに、この洗浄槽位置センサ５３に近接してレバー５４が揺動自在に取り付けられている。また、洗浄機本体１のレール７の取付板５５にはレバー５４に対向する位置にレバー押圧用の突起部５６が形成されている。 Further, as shown in FIGS. 13A and 13B, a mounting plate 52 is provided at the rear end of the cleaning tank 2, and a cleaning tank position sensor 53 is fixed to the mounting plate 52. A lever 54 is swingably attached in the vicinity of the tank position sensor 53. Further, a protrusion 56 for pressing the lever is formed on the mounting plate 55 of the rail 7 of the cleaning machine body 1 at a position facing the lever 54.

この洗浄槽位置センサ５３は、洗浄槽２が最終収納位置にあるか否かを検出するものであって、例えば投光部５３ａと受光部５３ｂとが対向配置されたフォトカプラからなる。そして、図１３(イ)に示すように、レバー５４が突起部５５から離間していて投光部５３ａと受光部５３ｂとの間に位置するときには、受光部５３ｂの出力がオフするので、洗浄槽２が最終収納位置から前方に引き出されていることが検出され、また、図１３(ロ)に示すように、レバー５４が突起部５５に押圧されて投光部５３ａと受光部５３ｂとの間から離脱したときには、受光部５３ｂの出力がオンするので、洗浄槽２が最終収納位置に収納されたことが検出されるように構成されている。 The cleaning tank position sensor 53 detects whether or not the cleaning tank 2 is in the final storage position, and is composed of, for example, a photocoupler in which a light projecting unit 53a and a light receiving unit 53b are arranged to face each other. Then, as shown in FIG. 13 (a), when the lever 54 is separated from the projection 55 and is positioned between the light projecting portion 53a and the light receiving portion 53b, the output of the light receiving portion 53b is turned off. It is detected that the tank 2 is drawn forward from the final storage position, and as shown in FIG. 13 (b), the lever 54 is pressed by the projection 55, and the light projecting part 53a and the light receiving part 53b are Since the output of the light receiving portion 53b is turned on when the separation is left, it is configured that it is detected that the cleaning tank 2 is stored in the final storage position.

次に、上記構成を備えた食器洗浄機の動作について説明する。
(１)洗浄槽２の収納移動および引き出し移動に伴う内蓋１０の開閉動作
洗浄槽２が洗浄機本体１から引き出された状態では、図３(ロ)に示すように、洗浄機本体１の案内ピン１４は洗浄槽溝１５から離脱しており、また内蓋１０は蓋用スプリング３８（図４、図８）で洗浄機本体１の前方開口側に引っ張られているので、各案内ピン１４は内蓋１０の長穴１６内の外方端側の位置（以下、引き出し操作位置という）にある。このため、内蓋１０のカムピン３７はクランプ部材２６のカム溝２２の最上方位置に移行しており、内蓋１０は上昇して洗浄槽２の上面開口部４から離脱している。 Next, operation | movement of the dishwasher provided with the said structure is demonstrated.
(1) Opening / Closing Operation of Inner Lid 10 Accompanying Storage and Drawer Movement of Washing Tank 2 When the washing tank 2 is pulled out from the washing machine main body 1, as shown in FIG. Since the guide pin 14 is detached from the cleaning tank groove 15 and the inner lid 10 is pulled to the front opening side of the cleaner body 1 by the lid spring 38 (FIGS. 4 and 8), each guide pin 14 is pulled. Is at a position on the outer end side in the long hole 16 of the inner lid 10 (hereinafter referred to as a drawer operation position). For this reason, the cam pin 37 of the inner lid 10 has moved to the uppermost position of the cam groove 22 of the clamp member 26, and the inner lid 10 has been lifted away from the upper surface opening 4 of the cleaning tank 2.

この状態から洗浄槽２を収納方向Ａへ次第に移動させていくと、洗浄槽２が図４および図５に示す中間位置に到達するまでの範囲では、洗浄槽溝１５は案内ピン１４に依然として係合しないので、案内ピン１４は引き出し操作位置に保持されている。 When the cleaning tank 2 is gradually moved in the storage direction A from this state, the cleaning tank groove 15 is still engaged with the guide pin 14 until the cleaning tank 2 reaches the intermediate position shown in FIGS. Since they do not match, the guide pin 14 is held in the pulling operation position.

そして、洗浄槽２が図４および図５に示す中間位置に到達すると、図５(ロ)に示すように、洗浄槽２の手前側当接部１７が案内ピン１４に当接する。洗浄槽２をさらに収納方向Ａへ移動させると、案内ピン１４が洗浄槽２の手前側当接部１７によって押圧されるので、案内ピン１４は内蓋１０の長穴１６に沿って内方に向けて摺動するとともに、洗浄槽溝１５内に嵌入する。これに伴いプッシュレバー１３が図中反時計方向に回動する。このプッシュレバー１３の回動によって内蓋１０が蓋用スプリング３８の引っ張り力に抗して収納方向Ａへ押し移動される。そのため、内蓋１０のカムピン３７はクランプ部材２６のカム溝２２の最上方位置から最下方位置に向けて移行し、その結果、内蓋１０が洗浄槽２の上面開口部４に向けて下降する。 When the cleaning tank 2 reaches the intermediate position shown in FIGS. 4 and 5, the near-side contact portion 17 of the cleaning tank 2 contacts the guide pin 14 as shown in FIG. When the cleaning tank 2 is further moved in the storage direction A, the guide pin 14 is pressed by the near side contact portion 17 of the cleaning tank 2, so that the guide pin 14 is inward along the elongated hole 16 of the inner lid 10. And slides in the cleaning tank groove 15. As a result, the push lever 13 rotates counterclockwise in the figure. As the push lever 13 rotates, the inner lid 10 is pushed and moved in the storage direction A against the pulling force of the lid spring 38. Therefore, the cam pin 37 of the inner lid 10 moves from the uppermost position of the cam groove 22 of the clamp member 26 toward the lowermost position, and as a result, the inner lid 10 descends toward the upper surface opening 4 of the cleaning tank 2. .

洗浄槽２を最終の収納位置まで移動させると、図７(ロ)に示すように、各案内ピン１４は内蓋１０の長穴１６内の内方端側の位置（以下、収納操作位置という）に移行する。これに伴い、内蓋１０のカムピン３７はクランプ部材２６のカム溝２２の最下方位置に移行し、その結果、各クランプ部材２６の当接部２５が、洗浄槽２の受け止め面３５に当接し、クランプ部材２６の開閉方向Ｃへの移動が阻止されるとともに、内蓋１０が洗浄槽２側に押し付けられて洗浄槽２の上面開口部４が確実に封止される。 When the cleaning tank 2 is moved to the final storage position, as shown in FIG. 7B, each guide pin 14 is positioned on the inner end side in the long hole 16 of the inner lid 10 (hereinafter referred to as a storage operation position). ). Along with this, the cam pin 37 of the inner lid 10 moves to the lowest position of the cam groove 22 of the clamp member 26, and as a result, the contact portion 25 of each clamp member 26 contacts the receiving surface 35 of the cleaning tank 2. The clamp member 26 is prevented from moving in the opening / closing direction C, and the inner lid 10 is pressed against the cleaning tank 2 so that the upper surface opening 4 of the cleaning tank 2 is reliably sealed.

一方、洗浄槽２を最終の収納位置から引き出し方向Ｂへ移動させるときは、上記の説明とは逆の動作となる。すなわち、洗浄槽２の手前側当接部１７による案内ピン１４への押圧作用が解除されるとともに、内蓋１０には蓋用スプリング３８の引っ張り力が加わるため、案内ピン１４は内蓋１０の長穴１６に沿って収納操作位置から引き出し操作位置に向けて摺動するとともに、内蓋１０のカムピン３７はクランプ部材２６のカム溝２２の最下方位置から最上方位置まで移行する。その結果、内蓋１０が洗浄槽２の上部開口部から離間して開状態となる。 On the other hand, when the cleaning tank 2 is moved in the pulling direction B from the final storage position, the operation is the reverse of the above description. That is, the pressing action on the guide pin 14 by the front side abutting portion 17 of the cleaning tank 2 is released, and the pulling force of the lid spring 38 is applied to the inner lid 10. The cam pin 37 of the inner lid 10 moves from the lowermost position to the uppermost position of the cam groove 22 of the clamp member 26 while sliding along the elongated hole 16 from the storing operation position toward the pulling operation position. As a result, the inner lid 10 is separated from the upper opening of the cleaning tank 2 and is opened.

このように、洗浄槽２を収納移動および引き出し移動すると、これに応じて案内レバー１１、クランプ部材２６のカム溝２２、および蓋用スプリング３８の相互作用によって内蓋１０が連動して内蓋１０の開閉操作が行われることになる。 As described above, when the cleaning tank 2 is moved and retracted, the inner lid 10 is interlocked by the interaction of the guide lever 11, the cam groove 22 of the clamp member 26, and the lid spring 38 according to this movement. The opening / closing operation is performed.

(２)洗浄槽２の収納移動および引き出し移動に伴うトグル機構２７の動作
洗浄槽２を洗浄機本体１の収納空間に収納した状態では、図６、図７(イ)に示すように、洗浄槽２から後方に向けて突出する係合用ピン３６が、レバー２９の係合用切欠き２８内に嵌入し、コイルスプリング３０の付勢力に起因するレバー２９の回動力が、洗浄槽２の収納移動方向Ａ側に作用する。 (2) Operation of the toggle mechanism 27 in accordance with the storage movement and the drawer movement of the cleaning tank 2 In the state where the cleaning tank 2 is stored in the storage space of the main body 1 of the cleaning machine, as shown in FIGS. The engaging pin 36 protruding rearward from the tank 2 is fitted into the engaging notch 28 of the lever 29, and the rotational force of the lever 29 caused by the urging force of the coil spring 30 causes the cleaning movement of the cleaning tank 2. Acts on the direction A side.

その際、前述のように、洗浄槽２の手前側当接部１７が案内ピン１４に当接してこれを収納移動方向Ａ側に押圧しているので、内蓋１０のカムピン３７がカム溝２２内における最下方位置に位置し、その結果、内蓋１０が洗浄槽２の上面開口部４を密閉した状態となる。 At this time, as described above, the front contact portion 17 of the cleaning tank 2 contacts the guide pin 14 and presses it toward the storage movement direction A side, so that the cam pin 37 of the inner lid 10 is connected to the cam groove 22. The inner lid 10 is in a state of sealing the upper surface opening 4 of the cleaning tank 2 as a result.

この収納状態から洗浄槽２を引き出し移動方向Ｂ側へ移動すると、レバー２９がコイルスプリング３０の付勢力に抗して引き出し移動方向Ｂ側に回動され、レバー２９が図５(イ)に示した設定切換位置Ｄを越えると、図３(イ)、図４に示すように、コイルスプリング３０の付勢力に起因するレバー２９の回動力が、引き出し移動方向Ｂ側に作用するように切り換わる。これにより、コイルスプリング３０の付勢力によって、洗浄槽２が引き出し移動方向Ｂ側に押し出され、その後、係合用ピン３６が係合用切欠き２８から外れるとともに、前述のように内蓋１０の上昇による洗浄槽２の上面開口部４の閉鎖が解除されるので、洗浄槽２を洗
浄機本体１から引き出すことができるようになる。 When the cleaning tank 2 is moved to the pulling movement direction B side from this stored state, the lever 29 is rotated to the pulling movement direction B against the urging force of the coil spring 30, and the lever 29 is shown in FIG. When the set switching position D is exceeded, the turning force of the lever 29 caused by the urging force of the coil spring 30 is switched so as to act on the pulling movement direction B side as shown in FIGS. . As a result, the urging force of the coil spring 30 pushes the cleaning tank 2 toward the pulling movement direction B, and then the engaging pin 36 is removed from the engaging notch 28 and the inner lid 10 is raised as described above. Since the closing of the upper surface opening 4 of the cleaning tank 2 is released, the cleaning tank 2 can be pulled out from the cleaning machine main body 1.

この引き出し状態から逆に洗浄槽２を収納移動方向Ａ側へ押し込むと、洗浄槽２から突出する係合用ピン３６がレバー２９の係合用切欠き２８内に嵌入してこれを押圧するので、引き出し時とは逆に、レバー２９をコイルスプリング３０の付勢力に抗して収納移動方向Ａ側に回動させる。そして、レバー２９が設定切換位置Ｄを越えると、レバー２９の回動力が収納移動方向Ａ側に作用するように切り換わるので、コイルスプリング３０の付勢力によって洗浄槽２が収納移動方向Ａ側に引き込まれる。 When the washing tub 2 is pushed back in the storage movement direction A side from this pulled out state, the engaging pin 36 protruding from the washing tub 2 is inserted into the engaging notch 28 of the lever 29 and presses it. On the contrary, the lever 29 is rotated in the storage movement direction A side against the urging force of the coil spring 30. When the lever 29 exceeds the setting switching position D, the turning force of the lever 29 is switched so as to act on the storage movement direction A side, so that the cleaning tank 2 is moved to the storage movement direction A side by the urging force of the coil spring 30. Be drawn.

このように、洗浄槽２の収納移動および引き出し移動に伴って、トグル機構２７のレバー２９に対するコイルスプリング３０の付勢力（回動作用方向）が、設定切換位置Ｄを境として時計方向と反時計方向とに切り換わるので、洗浄槽２の収納移動および引き出し移動を小さな操作力でもって行うことが可能になる。 As described above, the energizing force (rotating action direction) of the coil spring 30 against the lever 29 of the toggle mechanism 27 is moved clockwise and counterclockwise with the setting switching position D as a boundary as the cleaning tank 2 is moved in and out. Thus, the cleaning tank 2 can be moved and retracted with a small operating force.

本実施形態の食器洗浄機は、上述の如き構成により、洗浄槽２の収納移動方向Ａへの移動により、内蓋１０の降下による洗浄槽２の上面開口部４の閉鎖を行うものであるが、上記で説明した構成に加えて、下記の構成を備えるものである。 The dishwasher according to the present embodiment closes the upper surface opening 4 of the cleaning tank 2 by the lowering of the inner lid 10 by moving the cleaning tank 2 in the storage movement direction A by the configuration as described above. In addition to the configuration described above, the following configuration is provided.

洗浄槽２の収納移動方向Ａへの移動により、内蓋１０の降下による洗浄槽２の上面開口部４の閉鎖を行うときに、内蓋１０の後端が左右方向にずれることを規制する、蓋後端横方向規制部Ｒを備える。
具体的には、内蓋１０が左右方向に大きくずれながら収納移動方向Ａへ移動しようとした場合にも、取付固定部１２と内蓋１０の後方側における左右の両側端とが当接することで、内蓋１０が左右方向へのずれが規制される。すなわち、取付固定部１２が蓋後端横方向規制部Ｒとしての機能を兼ね備えている。（図８参照。） When the upper surface opening 4 of the cleaning tank 2 is closed by the lowering of the inner lid 10 by moving the cleaning tank 2 in the storage movement direction A, the rear end of the inner lid 10 is restricted from shifting in the left-right direction. A lid rear end lateral direction restricting portion R is provided.
Specifically, even when the inner lid 10 is about to move in the storage movement direction A while being largely displaced in the left-right direction, the mounting fixing portion 12 and the left and right side ends on the rear side of the inner lid 10 are in contact with each other. The displacement of the inner lid 10 in the left-right direction is restricted. That is, the attachment fixing portion 12 also has a function as the lid rear end lateral direction restricting portion R. (See Figure 8.)

このようにすることで、洗浄機本体（本体ケーシング）１に対する内蓋１０の後端の左右方向へのずれが規制される。洗浄機本体（本体ケーシング）１はその左右の両側面、天面、底面、および、後面の５面を鉄などの金属板により直方体を成す箱状に形成されているものであり、洗浄機本体（本体ケーシング）１の後部においては、その剛性が大きくなっているから、変形が生じにくくなっているものであり、レール７により洗浄機本体（本体ケーシング）１に取り付けられている洗浄槽２と洗浄機本体（本体ケーシング）１との相対的な位置のずれは生じにくくなっているから、洗浄機本体（本体ケーシング）１に対する内蓋１０の後端の左右方向へのずれが規制されることで、洗浄槽２と内蓋１０との相対的なずれも生じにくいものとなる。 By doing in this way, the shift | offset | difference to the left-right direction of the rear end of the inner cover 10 with respect to the washing machine main body (main body casing) 1 is controlled. The washing machine body (body casing) 1 is formed in a box shape in which the left and right side surfaces, the top surface, the bottom surface, and the rear surface are formed into a rectangular parallelepiped with a metal plate such as iron. Since the rigidity of the rear portion of the (main body casing) 1 is large, deformation is less likely to occur, and the cleaning tank 2 attached to the cleaning machine main body (main body casing) 1 by rails 7 Since the relative displacement with respect to the cleaning machine main body (main body casing) 1 is less likely to occur, the displacement of the rear end of the inner lid 10 with respect to the cleaning machine main body (main body casing) 1 in the left-right direction is restricted. Thus, the relative displacement between the cleaning tank 2 and the inner lid 10 is less likely to occur.

このようにして、内蓋１０の後端の左右方向へのずれに起因する、洗浄槽２の上面開口部４の閉鎖不良による洗浄用湯水の洗浄槽２からの漏出を防止している。 In this way, leakage from the cleaning tank 2 for cleaning hot water due to poor closing of the upper surface opening 4 of the cleaning tank 2 due to the lateral displacement of the rear end of the inner lid 10 is prevented.

さらに、本実施形態の食器洗浄機は、浄槽２の収納移動方向Ａへの移動により、内蓋１０の降下による洗浄槽２の上面開口部４の閉鎖を行うときに、内蓋１０の前端が洗浄槽２と左右方向にずれることを規制する、蓋前端横方向規制部Ｆを備える。 Furthermore, when the dishwasher of this embodiment closes the upper surface opening part 4 of the washing tank 2 by the fall of the inner lid 10 by the movement of the cleaning tank 2 in the storage movement direction A, the front end of the inner lid 10 Is provided with a lid front end lateral direction restricting portion F that restricts the cleaning tank 2 from shifting in the left-right direction.

この蓋前端横方向規制部Ｆの場合は、洗浄機本体（本体ケーシング）１は前面が開口しているから、横方向の外力に対するその剛性は小さいものであり、輸送時や設置時の取扱不備などによって洗浄機本体（本体ケーシング）１は左右方向の歪みが生じるおそれがある。したがって、洗浄槽２と洗浄機本体（本体ケーシング）１との相対的な位置のずれは生じ易いものであるから、洗浄機本体（本体ケーシング）１に対する内蓋１０の前端の左右方向へのずれを規制しても、洗浄槽２と内蓋１０との横方向の相対的なずれは防止し難いものである。 In the case of the lid front end lateral regulating portion F, since the front surface of the washing machine main body (main body casing) 1 is open, its rigidity against a lateral external force is small, and handling inadequate during transportation and installation. There is a risk that the cleaning machine main body (main body casing) 1 may be distorted in the left-right direction. Accordingly, since the relative position between the cleaning tank 2 and the cleaning machine main body (main body casing) 1 is likely to shift, the front end of the inner lid 10 with respect to the cleaning machine main body (main body casing) 1 is shifted in the left-right direction. However, it is difficult to prevent the relative displacement between the cleaning tank 2 and the inner lid 10 in the lateral direction.

そこで、この蓋前端横方向規制部Ｆの場合は、洗浄槽２と内蓋１０との横方向の相対的なずれが生じないようにするために、以下の構成としている。 Therefore, in the case of the lid front end lateral direction restricting portion F, the following configuration is adopted in order to prevent the horizontal displacement between the cleaning tank 2 and the inner lid 10.

図１１、図１２、図１４に示すように、左右２つの蓋前端横方向規制部Ｆが、内蓋１０の前端部における左右両側から垂下形成されている。さらに具体的には、蓋前端横方向規制部Ｆは内蓋１０の前端部における左右両側から垂下形成されたときに、蓋前端横方向規制部Ｆが下に向けて外側に先広がりとなるように、略くの字状に成型された帯状の金属片を、内蓋１０の前端部における左右両側に止着して構成してある。さらに詳しく説明すると、略くの字状に成型された帯状の金属片の一端を、内蓋１０の前端部における左右両側に止着する部分から、略くの字状に成型された帯状の金属片の屈曲部までは略垂直に垂下した垂直部Ｖを構成し、略くの字状に成型された帯状の金属片の屈曲部から下の、上記一端に対する他端側が、洗浄槽２の外周側に向けて離れる方向に、下に向けて洗浄槽２を中心として外側に先広がりとなるように形成してあり、傾斜部ＲＣを構成する。なお、本実施例においては、蓋前端横方向規制部Ｆと、内蓋１０とは別部品としてあるが、蓋前端横方向規制部Ｆと、内蓋１０とを樹脂成形品などによって一体に形成してもよい。 As shown in FIG. 11, FIG. 12, and FIG. 14, the two right and left lid front end lateral restriction portions F are suspended from the left and right sides of the front end portion of the inner lid 10. More specifically, when the lid front end lateral regulating portion F is suspended from both the left and right sides of the front end portion of the inner lid 10, the lid front end lateral regulating portion F extends outwardly downward. In addition, a strip-shaped metal piece molded in a substantially square shape is fixed to both the left and right sides of the front end portion of the inner lid 10. More specifically, a strip-shaped metal piece molded into a generally U-shape from a portion where one end of a strip-shaped metal piece molded into a generally U-shape is fastened to the left and right sides of the front end portion of the inner lid 10. A vertical portion V that hangs substantially vertically is formed up to the bent portion of the piece, and the other end side with respect to the one end below the bent portion of the band-shaped metal piece formed in a substantially square shape is the outer periphery of the cleaning tank 2 It forms so that it may spread outward outside centering on the washing tank 2 toward the bottom in the direction which leaves | separates toward the side, and comprises the inclination part RC. In this embodiment, the lid front end lateral regulating portion F and the inner lid 10 are separate parts, but the lid front end lateral regulating portion F and the inner lid 10 are integrally formed of a resin molded product or the like. May be.

蓋前端横方向規制部Ｆの上下方向と直交する方向である、帯状の金属片の幅方向の中間部は、上下方向に沿って帯状に押し加工を施すことで、上下方向に帯状の滑らかな凸部を形成してある。この上下方向に帯状の滑らかな凸部が突出する方向は、蓋前端横方向規制部Ｆが内蓋１０の前端部における左右両側から垂下形成されたときに、左右の２つの蓋前端横方向規制部Ｆの間に向けた方向としてある。 The middle part in the width direction of the band-shaped metal piece, which is a direction orthogonal to the vertical direction of the lid front end lateral regulating part F, is formed into a band-like smooth in the vertical direction by pressing the band-shaped metal piece along the vertical direction. Protrusions are formed. The direction in which the belt-like smooth convex portion protrudes in the vertical direction is such that when the lid front end lateral direction restricting portion F is suspended from the left and right sides at the front end portion of the inner lid 10, The direction is between the parts F.

図１１に示すように、洗から洗浄槽２を引き出され、内蓋１０が上昇して洗浄槽２の上面開口部４から離脱した状態では、略くの字状に成型された帯状の金属片から成る蓋前端横方向規制部Ｆと洗浄槽２との間には間隙があり、蓋前端横方向規制部Ｆは洗浄槽２から離れた非接触状態となっている。（図１１は正面視左側の蓋前端横方向規制部Ｆと洗浄槽２との位置関係を示している。）また、図１２に示すように、洗浄槽２が洗浄機本体１に収納移動され、内蓋１０が閉状態となった状態では、略くの字状に成型された帯状の金属片から成る蓋前端横方向規制部Ｆは、洗浄槽２の上縁の外周縁と当接し、洗浄槽２と内蓋１０左右方向の相対位置にずれが生じないような状態となっており、このずれが生じていない状態で内蓋１０が洗浄槽２側に押し付けられて洗浄槽２の上面開口部４が確実に封止される。 As shown in FIG. 11, in the state where the washing tank 2 is drawn out from the washing and the inner lid 10 is lifted and detached from the upper surface opening 4 of the washing tank 2, a strip-shaped metal piece molded in a substantially square shape. There is a gap between the lid front end lateral regulating portion F and the cleaning tank 2, and the lid front end lateral regulating portion F is in a non-contact state away from the cleaning tank 2. (FIG. 11 shows the positional relationship between the lid front end lateral regulating portion F on the left side when viewed from the front and the cleaning tank 2.) Also, as shown in FIG. In the state where the inner lid 10 is in the closed state, the lid front end lateral restriction portion F made of a strip-shaped metal piece molded in a substantially U shape comes into contact with the outer peripheral edge of the upper edge of the cleaning tank 2, The cleaning tank 2 and the inner lid 10 are in a state in which the relative positions in the left and right directions are not displaced, and the inner lid 10 is pressed against the cleaning tank 2 in a state in which this displacement does not occur, and the upper surface of the cleaning tank 2 The opening 4 is securely sealed.

洗浄機本体（本体ケーシング）１に洗浄槽２を収納する、または、洗浄機本体（本体ケーシング）１から洗浄槽２を引き出すことに伴う、内蓋１０の前後方向（図１におけるＡまたはＢに沿った方向）の移動は、上述したように、プッシュレバー１３の前後方向の遥動によって行われるものであるから、洗浄機本体（本体ケーシング）１に洗浄槽２を収納する、または、引き出すことに伴い内蓋１０が上下に移動することになる、すなわち、洗浄槽２と内蓋１０とが連動することになる洗浄槽２の収納位置の範囲（移動範囲）である洗浄槽−内蓋連動収納範囲に洗浄槽２が位置するときには、洗浄槽２の収納方向（図１におけるＡまたはＢに沿った方向）の移動量と、内蓋１０の前後方向（図１におけるＡまたはＢに沿った方向）の移動量は等しい。なお、上記の洗浄槽−内蓋連動収納範囲とは、ピン１４と洗浄槽２の手前側当接部１７とが当接する、または、案内ピン１４が洗浄槽溝１５内に嵌入する洗浄槽２の収納位置の範囲ということになる。 The cleaning tank 2 is housed in the cleaning machine main body (main body casing) 1 or the front / rear direction of the inner lid 10 (in A or B in FIG. 1) when the cleaning tank 2 is pulled out from the cleaning machine main body (main body casing) 1. As described above, the movement in the direction along the direction is performed by the swinging of the push lever 13 in the front-rear direction, so that the cleaning tank 2 is accommodated in or removed from the cleaning machine body (main body casing) 1. Accordingly, the inner lid 10 moves up and down, that is, the cleaning tank-inner lid interlock, which is the range (movement range) of the storage position of the cleaning tank 2 in which the cleaning tank 2 and the inner lid 10 are interlocked. When the cleaning tank 2 is located in the storage range, the movement amount of the cleaning tank 2 in the storage direction (direction along A or B in FIG. 1) and the front-rear direction of the inner lid 10 (along A or B in FIG. 1). Direction) Arbitrariness. The above cleaning tank - and the inner lid interlock housing range, the pin 14 and the front-side contact part 17 of the cleaning tank 2 comes into contact, or, wash the guide pin 14 you fitted into the cleaning tank groove 15 Kiyoshi This is the range of the storage position of the tank 2.

上記のように洗浄槽−内蓋連動収納範囲に洗浄槽２が位置するときには、洗浄槽２の収納方向（図１におけるＡまたはＢに沿った方向）の移動量と、内蓋１０の前後方向（図１におけるＡまたはＢに沿った方向）の移動量は等しいから、洗浄機本体（本体ケーシング）１への洗浄槽２の収納、または、洗浄機本体（本体ケーシング）１からの洗浄槽２の引き出しに伴い、内蓋１０がその最上方位置と最下方位置との中間位置（図５参照）に位置し、ピン１４と洗浄槽２の手前側当接部１７とが当接する、または、案内ピン１４が洗浄槽溝１５内に嵌入する収納位置の範囲に洗浄槽２が位置するときには、蓋前端横方向規制部Ｆが洗浄槽２と当接した場合にも、蓋前端横方向規制部Ｆと洗浄槽２との間には、前後方向（図１におけるＡまたはＢに沿った方向）の摺動が生じないことになり、前後方向（図１におけるＡまたはＢに沿った方向）の摺動に起因する磨耗や蓋前端横方向規制部Ｆの変形が生じないから好都合である。 When the cleaning tank 2 is located in the cleaning tank-inner lid interlocking storage range as described above, the moving amount of the cleaning tank 2 in the storage direction (direction along A or B in FIG. 1) and the front-rear direction of the inner lid 10 Since the amount of movement in the direction along A or B in FIG. 1 is the same, the cleaning tank 2 is stored in the cleaning machine body (main body casing) 1 or the cleaning tank 2 from the cleaning machine body (main body casing) 1. When the inner lid 10 is pulled out, the inner lid 10 is positioned at an intermediate position between the uppermost position and the lowermost position (see FIG. 5), and the pin 14 and the front side abutting portion 17 of the cleaning tank 2 abut, or when the guide pin 14 is positioned washing tank 2 is in the range of to that retract and position fitted into the cleaning tank groove 15, even when the lid front lateral regulation portion F is in contact with the washing tank 2 equivalents, lid front transverse Between the regulation part F and the cleaning tank 2, there is a front-rear direction (A or B in FIG. 1). (Sliding direction) is not generated, and it is advantageous because there is no wear or deformation of the lid front end lateral regulating part F due to sliding in the front-rear direction (direction along A or B in FIG. 1). It is.

また、蓋前端横方向規制部Ｆにおいて略くの字状に成型された帯状の金属片の屈曲部から下側が、洗浄槽２の外周側に向けて離れる方向に、下に向けて外側に先広がりとなるように形成してあり、傾斜部ＲＣを構成するものであるから、洗浄機本体（本体ケーシング）１への洗浄槽２の収納に伴って内蓋１０が降下し始める際に、洗浄槽２と内蓋１０との横方向のずれの大きさが多少大きい場合にも、傾斜部ＲＣによってずれが修正されるから好都合である。 In addition, the lower side from the bent portion of the band-shaped metal piece molded in a substantially square shape in the lid front end lateral restriction portion F is directed outward in the direction away from the outer peripheral side of the cleaning tank 2. Since it is formed so as to expand and constitutes the inclined portion RC, the cleaning is performed when the inner lid 10 starts to descend as the cleaning tank 2 is stored in the cleaning machine main body (main body casing) 1. Even when the lateral displacement between the tank 2 and the inner lid 10 is somewhat large, it is advantageous because the displacement is corrected by the inclined portion RC.

さらに、蓋前端横方向規制部Ｆの上下方向と直交する方向である、帯状の金属片の幅方向の中間部は、上下方向に沿って帯状に押し加工を施すことで、上下方向に帯状の滑らかな凸部を形成してあり、この上下方向に帯状の滑らかな凸部が突出する方向は、蓋前端横方向規制部Ｆが内蓋１０の前端部における左右両側から垂下形成された状態で、左右の２つの蓋前端横方向規制部Ｆの間に向けた方向としてあるから、蓋前端横方向規制部Ｆが洗浄槽２の上縁の外周縁と当接して上下方向に摺動した時にも、洗浄槽２の上縁の外周縁が蓋前端横方向規制部Ｆによって損傷しにくいものとなり好都合である。 Furthermore, the middle part of the width direction of the strip-shaped metal piece, which is a direction orthogonal to the vertical direction of the lid front end lateral regulating portion F, is formed into a strip shape in the vertical direction by pressing the strip along the vertical direction. A smooth convex part is formed, and the direction in which the belt-like smooth convex part protrudes in the vertical direction is a state in which the lid front end lateral restriction part F is suspended from the left and right sides of the front end part of the inner lid 10. Since the direction is between the left and right two lid front end lateral restriction portions F, when the lid front end lateral restriction portion F comes into contact with the outer peripheral edge of the upper edge of the cleaning tank 2 and slides in the vertical direction, However, the outer peripheral edge of the upper edge of the cleaning tank 2 is not easily damaged by the lid front end lateral regulating portion F, which is convenient.
