Description

この発明は、食器洗浄機に関するものである。   The present invention relates to a dishwasher.

従来の食器洗浄機としては、食器洗浄機本体から洗浄槽を手前に引き出し、洗浄槽内に食器を収納して食器の洗浄を行うもので、洗浄槽を食器洗浄機本体内から手前に引き出したとき、洗浄槽内に収納された食器の重さにより洗浄槽が下がり、洗浄槽を食器洗浄機本体内に押し込むときの操作力が大変大きくなってしまうことを回避するために、洗浄槽を斜め上方にスライドさせて引き出すものがある（例えば、特許文献１参照）。 As a conventional dishwasher, the washing tub is pulled out from the main body of the dishwasher, the dishes are stored in the washing tub and the dishes are washed. The washing tub is pulled out from the main body of the dishwasher. In order to prevent the washing tank from falling due to the weight of the tableware stored in the washing tank and the operation force when pushing the washing tank into the dishwasher main body becomes very large, the washing tank is slanted. There is one that slides upward and pulls out (see, for example, Patent Document 1).

特許３１２９３１２号公報（第２−３頁、第１図）Japanese Patent No. 3129312 (page 2-3, FIG. 1)

従来の食器洗浄機では、洗浄槽内に収納された食器の重さにより洗浄槽を引き出したとき、洗浄槽が下がってしまい、洗浄槽を押し込むときの操作力が大変大きくなってしまうという課題を解決するために、洗浄槽を斜め上方にスライドして引き出すようにしたが、洗浄槽を引き出す際に洗浄槽を上方に持ち上げる方向の力が必要となってしまい、洗浄槽を押し込む際の操作力は小さくとも、引き出す際の操作力が大きくなってしまうという問題点があった。
また、洗浄槽を引き出したとき、洗浄槽の下がりを防止するためには、大荷重に耐えるレールを使う必要があり、その結果レール事態が大きくなり、食器洗浄機本体の寸法が同じ場合、洗浄槽の寸法が小さくなり、洗浄容量が犠牲になってしまうし、レール自体も高価なものになってしまうという問題点もあった。 In the conventional dishwasher, when the washing tank is pulled out due to the weight of the tableware stored in the washing tank, the washing tank is lowered, and the operation force when pushing the washing tank becomes very large. In order to solve this problem, the cleaning tank was slid upwards and pulled out, but when pulling out the cleaning tank, a force in the direction of lifting the cleaning tank was required, and the operating force when pushing the cleaning tank Even if it is small, there is a problem that the operation force when pulling out becomes large.
Also, when the washing tank is pulled out, in order to prevent the washing tank from falling, it is necessary to use a rail that can withstand a heavy load.As a result, the situation of the rail becomes large and the dimensions of the dishwasher body are the same. There were also problems that the size of the tank was reduced, the cleaning capacity was sacrificed, and the rail itself was expensive.

この発明は、上記のよう課題を解決するためになされたもので、簡単な構造で洗浄槽を軽い操作力により引き出し／押し込むことができ、操作性を向上することができる食器洗浄機を得るものである。   The present invention has been made to solve the above-described problems, and obtains a dishwasher capable of pulling out / pushing a washing tub with a light operating force with a simple structure and improving operability. It is.

この発明に係る食器洗浄機は、上方を開口し食器が収納される洗浄槽と、前記洗浄槽内の食器を洗浄する洗浄ノズルと、前記洗浄槽の外面に固定される第１のスライドレールと、前記洗浄槽に回転可能に固定された第１のローラと、食器洗浄機本体に固定され、前記第１のローラの上方および下方に摺動面をもつ第２のスライドレールと、前記食器洗浄機本体に回転可能に固定され、前記第１のスライドレールを下方から支持する第２のローラとを備え、前記洗浄槽を食器洗浄機本体の前面側に引き出せる食器洗浄機において、前記第２のスライドレールは、上部レールと下部レールとで構成され、前記食器洗浄機本体の前面側が低くなるよう傾斜させて配設しており、その取り付け傾斜角度θを、θ＝ｔａｎ -1 （（第２のスライドレールの上部レールと下部レールとの間隔−第１のローラの直径）／第１のローラの移動可能距離）としており、また、前記洗浄槽が食器洗浄機本体から前面側に引き出された状態で、前記第２のローラの近傍に位置する第１のスライドレールの部分を、所定角度αだけ上方に曲げて形成したものである。 The dishwasher according to the present invention includes a washing tub that opens upward and stores the tableware, a washing nozzle that cleans the tableware in the washing tub, and a first slide rail that is fixed to the outer surface of the washing tub. A first roller rotatably fixed to the washing tank, a second slide rail fixed to the dishwasher body and having sliding surfaces above and below the first roller, and the dishwasher A dishwasher which is rotatably fixed to the machine body and has a second roller for supporting the first slide rail from below, wherein the washing tank can be pulled out to the front side of the dishwasher body. The slide rail is composed of an upper rail and a lower rail, and is arranged so as to be inclined so that the front side of the dishwasher main body is lowered , and its mounting inclination angle θ is θ = tan −1 ((second Of slide rail The distance between the upper rail and the lower rail-the diameter of the first roller) / the movable distance of the first roller), and in the state where the washing tank is pulled out from the dishwasher body to the front side, A portion of the first slide rail located in the vicinity of the second roller is formed by bending upward by a predetermined angle α .

この発明は、食器洗浄機本体に第２のスライドレールを食器洗浄機本体の前面側が低くなるよう傾斜させて配設したので、洗浄槽を食器洗浄機本体内に収納する際の洗浄槽を押し込む操作力を低減できる食器洗浄機を得ることができる。
また、傾斜角度をθ＝ｔａｎ -1 （（第２のスライドレールの上部レールと下部レールとの間隔−第１のローラの直径）／第１のローラの移動可能距離）とし、また、洗浄槽が食器洗浄機本体から前面側に引き出された状態で、第２のローラの近傍に位置する第１のスライドレールの部分を、所定角度αだけ上方に曲げて形成したので、洗浄槽を食器洗浄機本体から引き出した状態で、第１のスライドレールが水平状態となるため、洗浄槽を食器洗浄機本体内に収納する際に、洗浄槽を押し込む操作力が大きくなるようなことはなく、操作性のよい食器洗浄機を実現することができる。 According to the present invention, the second slide rail is disposed in the dishwasher main body so as to be inclined so that the front side of the dishwasher main body is lowered, so that the cleaning tank is pushed into the dishwasher main body. A dishwasher capable of reducing the operating force can be obtained.
The inclination angle is θ = tan −1 ((distance between upper rail and lower rail of second slide rail−first roller diameter) / movable distance of first roller), and cleaning tank Since the first slide rail portion located near the second roller is bent upward by a predetermined angle α in the state that the tub is pulled out from the main body of the dishwasher, the washing tub is dishwashed. Since the first slide rail is in the horizontal state when pulled out from the machine body, the operation force to push the washing tank does not increase when the washing tank is stored in the dishwasher body. A good dishwasher can be realized.

1 is a cross-sectional view showing a dishwasher according to Embodiment 1 for carrying out the present invention, in which (a) the washing tub is housed in the dishwasher body, (b) the washing tub is a dishwasher. FIG. 2 is an explanatory view showing the operating state of the rail portion, (a) a state where the washing tub is housed in the dishwasher body, and (b) a state where the washing tub is drawn out from the main body. It is in a state pulled out from the body. In the figure, the dishwasher main body 1 has a front opening, and a cleaning tank 2 having an upper opening is provided in the interior thereof so that it can be drawn forward. Inside the washing tank 2, there are provided a dish basket 4 for storing the tableware 3 and a washing nozzle 5 for spraying washing water to wash the tableware 3. The cleaning tank 2 is provided with a moving rail 6 (first slide rail in the claims), and further provided with a moving roller 7 (first roller in the claims) integrally with the moving rail 6. It has been. A fixed rail 8 (second slide rail in the claims) and a fixed roller 9 (second roller in the claims) are provided on the inner side surface of the dishwasher main body 1. The moving rail 6 is supported from below by a fixed roller 9. The fixed rail 8 has a substantially U-shaped cross section and is composed of an upper rail 8a and a lower rail 8b, and the moving roller 7 is disposed between the upper rail 8a and the lower rail 8b.

固定レール８は、引き出し側（食器洗浄機本体１の前面側）が低くなるように傾斜させて食器洗浄機本体１の内部側面に取り付けられている。そして、その傾斜角度θは、θ＝ｔａｎ−１（ｙ／ｘ）で、ｙ＝Ａ−Ｂであり、Ａは固定レール８の上部レール８ａと下部レール８ｂの間隔、Ｂは移動ローラ７の直径、Ｘは洗浄槽２が食器洗浄機本体１に収納された状態から手前に引き出された状態になるまでに移動ローラ７が移動する水平距離とする。   The fixed rail 8 is attached to the inner side surface of the dishwasher main body 1 so as to be inclined so that the drawer side (front side of the dishwasher main body 1) is lowered. The inclination angle θ is θ = tan−1 (y / x), y = A−B, A is the distance between the upper rail 8 a and the lower rail 8 b of the fixed rail 8, and B is the moving roller 7. The diameter, X, is the horizontal distance that the moving roller 7 moves from the state in which the washing tub 2 is housed in the dishwasher main body 1 to the state in which it is pulled out.

このように構成された食器洗浄機の洗浄槽の引き出す／押し込むときの動作について説明する。食器洗浄機本体１に収納されている洗浄槽２を引き出す（図１（ｂ）、図２（ｂ）の状態）ことで、洗浄槽２の上部開口部２ａが開放状態となり、食器３を洗浄槽２の内部の食器かご４に収納可能となる。食器３を収納したら、洗浄槽２を食器洗浄機本体１に押し込む（図１（ａ）、図２（ａ）の状態）。そして、操作パネル（図示せず）を操作して洗浄運転が開始される。給水・洗い・すすぎ等を自動で行い、洗浄運転終了後、洗浄槽２を食器洗浄機本体１より引き出し、洗浄された食器３を洗浄槽２内から取り出す。その後、洗浄槽２を食器洗浄機本体１内に押し込んで収納し、一連の操作を終える。 An operation when the washing tub of the dishwasher configured as described above is pulled out / pushed in will be described. By pulling out the washing tank 2 stored in the tableware washing machine main body 1 (the state shown in FIGS. 1B and 2B), the upper opening 2a of the washing tank 2 is opened, and the tableware 3 is washed. It can be stored in the tableware basket 4 inside the tank 2. When the tableware 3 is stored, the washing tub 2 is pushed into the tableware washing machine main body 1 (state shown in FIGS. 1A and 2A). Then, a cleaning operation is started by operating an operation panel (not shown). Water supply, washing, rinsing, etc. are performed automatically, and after the washing operation is completed, the washing tub 2 is pulled out from the dishwasher body 1 and the washed tableware 3 is taken out from the washing tub 2. Thereafter, the washing tub 2 is pushed into and stored in the dishwasher body 1 to complete a series of operations.

このように、洗浄槽２内への食器３の収納／洗浄槽２内からの食器３の取り出しの際には、洗浄槽２を食器洗浄機本体１内から引き出す／押し込む動作が行われる。洗浄槽２が食器洗浄機本体１に収納された状態では、移動ローラ７は固定レール８の奥の部分で支持され、固定ローラ９は移動レール６の手前の部分を支持する（図２（ａ）参照）。洗浄槽２の重心は、移動ローラ７と固定ローラ９の間に存在し、洗浄槽２の重さによって移動ローラ７は下側に押し付けられて、移動ローラ７は固定レール８の下部レール８ｂの上面に接している。このとき、移動レール６は水平状態となる。   Thus, when storing the tableware 3 in the washing tub 2 / taking out the tableware 3 from the washing tub 2, an operation of pulling out / pushing the washing tub 2 out of the tableware washing machine main body 1 is performed. In the state where the washing tub 2 is housed in the dishwasher main body 1, the moving roller 7 is supported by the back part of the fixed rail 8, and the fixed roller 9 supports the front part of the moving rail 6 (FIG. 2 (a). )reference). The center of gravity of the cleaning tank 2 exists between the moving roller 7 and the fixed roller 9, and the moving roller 7 is pressed downward by the weight of the cleaning tank 2, and the moving roller 7 is connected to the lower rail 8 b of the fixed rail 8. It touches the top surface. At this time, the moving rail 6 is in a horizontal state.

一方、洗浄槽２が食器洗浄機本体１から引き出された状態（図２（ｂ）参照）では、移動ローラ７は固定レール８の手前部分で支持され、固定ローラ９は移動レール６の奥の部分を支持する。このとき、洗浄槽２の重心は、固定ローラ９よりも手前側に存在する。洗浄槽２の重さは固定ローラ９により支持され、固定ローラ９を支点として移動ローラ７は上面に押し付けられ、移動ローラ７は固定レール８の上部レール８ａの下面に接している。   On the other hand, when the washing tub 2 is pulled out from the dishwasher main body 1 (see FIG. 2B), the moving roller 7 is supported by the front portion of the fixed rail 8, and the fixed roller 9 is located at the back of the moving rail 6. Support the part. At this time, the center of gravity of the cleaning tank 2 exists on the near side of the fixed roller 9. The weight of the cleaning tank 2 is supported by a fixed roller 9, the moving roller 7 is pressed against the upper surface with the fixed roller 9 as a fulcrum, and the moving roller 7 is in contact with the lower surface of the upper rail 8 a of the fixed rail 8.

このようにして、固定レール８を引き出し側（食器洗浄機本体１の前面側）が低くなるように傾斜して取り付け、その傾斜角度を上述した値θとすることで、洗浄槽２が引き出された状態での移動ローラ７は固定レール８の引き出し側（食器洗浄機本体１の前面側）の低くなっている上部レール８ａ部分に接するので、移動ローラ７の高さは洗浄槽２が食器洗浄機本体１に収納された状態と同じ高さとなる。これにより、移動レール６は水平状態のまま引き出される。   In this way, the fixing rail 8 is attached so as to be inclined so that the drawer side (the front side of the dishwasher main body 1) is low, and the cleaning tank 2 is drawn out by setting the inclination angle to the value θ described above. Since the moving roller 7 in contact with the upper rail 8a portion of the fixed rail 8 on the drawer side (the front side of the dishwasher main body 1) is lowered, the height of the moving roller 7 is such that the washing tub 2 can wash dishes. It becomes the same height as the state accommodated in the machine main body 1. Thereby, the moving rail 6 is pulled out in a horizontal state.

つまり、洗浄槽２が食器洗浄機本体１内に収納され、移動ローラ７が下部レール８ｂの上面に接している状態でも、洗浄槽２が食器洗浄機本体１内から引き出され、移動ローラ７が上部レール８ａの下面に接している状態でも、移動レール６は水平状態を保ち、したがって、移動レール６に固定された洗浄槽２の位置する高さは一定でかつ水平状態を保ち続ける。   That is, even when the washing tub 2 is housed in the dishwasher main body 1 and the moving roller 7 is in contact with the upper surface of the lower rail 8b, the washing tub 2 is pulled out from the dishwasher main body 1 and the moving roller 7 is Even when the moving rail 6 is in contact with the lower surface of the upper rail 8a, the moving rail 6 is kept in a horizontal state. Therefore, the height at which the cleaning tank 2 fixed to the moving rail 6 is located is kept constant and kept in the horizontal state.

このように、洗浄槽２を食器洗浄機本体１内から引き出した際に、収納された食器３の重さにより洗浄槽２が下がることがないので、洗浄槽２を食器洗浄機本体１内に収納する際に洗浄槽２を押し込む操作力が大きくなることはなく、操作性の良い食器洗浄機を実現することができる。   Thus, when the washing tub 2 is pulled out from the dishwasher main body 1, the washing tub 2 is not lowered due to the weight of the stored tableware 3. An operation force for pushing the washing tub 2 when storing is not increased, and a dishwasher with good operability can be realized.

実施の形態２．
図３は、この発明を実施するための実施の形態２における食器洗浄機のレール部の動作状態を示す説明図であり、（ａ）洗浄槽が食器洗浄機本体内に収納された状態、（ｂ）洗浄槽を食器洗浄基本体内から引き出した状態である。なお、上記実施の形態１の１〜５は本実施の形態２においても同様である。図において、洗浄槽２には移動レール６が設けられ、さらに移動レール６と一体に移動ローラ７が設けられている。食器洗浄機本体１の内部側面には固定レール８および固定ローラ９が設けられ、移動レール６は固定ローラ９により下方より支持されている。固定レール８は断面が略コの字形状で、上部レール８ａと下部レール８ｂとで構成されており、これら上部レール８ａと下部レール８ｂの間には移動ローラ７が配置される。 Embodiment 2. FIG.
FIG. 3 is an explanatory view showing an operation state of the rail portion of the dishwasher in the second embodiment for carrying out the present invention, (a) a state where the washing tank is housed in the dishwasher body, b) A state where the washing tank is pulled out from the basic body of dishwashing. In addition, 1-5 of the said Embodiment 1 is the same also in this Embodiment 2. FIG. In the figure, a moving rail 6 is provided in the cleaning tank 2, and a moving roller 7 is provided integrally with the moving rail 6. A fixed rail 8 and a fixed roller 9 are provided on the inner side surface of the dishwasher main body 1, and the moving rail 6 is supported by the fixed roller 9 from below. The fixed rail 8 has a substantially U-shaped cross section and is composed of an upper rail 8a and a lower rail 8b. A moving roller 7 is disposed between the upper rail 8a and the lower rail 8b.

固定レール８は、引き出し側（食器洗浄機本体１の前面側）が低くなるよう傾斜させて食器洗浄機本体１の内部側面に取り付けられている。そして、その傾斜角度θは、θ＝ｔａｎ−１（ｙ／ｘ）＋αで、ｙ＝Ａ−Ｂであり、Ａは固定レール８の上部レール８ａと下部レール８ｂの間隔、Ｂは移動ローラ７の直径、ｘは洗浄槽２が食器洗浄機本体１に収納された状態から手前に引き出された状態になるまでに移動ローラ７が移動する水平距離、αは洗浄槽２が食器洗浄機本体１から手前に引き出された状態で移動レール６が洗浄槽２の重みにより撓む撓み角とする。   The fixed rail 8 is attached to the inner side surface of the dishwasher main body 1 so that the drawer side (the front side of the dishwasher main body 1) is lowered. The inclination angle θ is θ = tan−1 (y / x) + α, y = A−B, A is the distance between the upper rail 8 a and the lower rail 8 b of the fixed rail 8, and B is the moving roller 7. , X is the horizontal distance that the moving roller 7 moves from the state in which the washing tub 2 is housed in the dishwasher main body 1 to the state in which the washing tub 2 is drawn to the near side, and α is the washing tank 2 in the dishwasher main body 1 It is assumed that the moving rail 6 is bent at a deflection angle due to the weight of the cleaning tank 2 in a state of being pulled out from the front.

このように構成された食器洗浄機の洗浄槽の引き出す／押し込むときの動作について説明する。上記実施の形態1と同様に、洗浄槽２内への食器３（図示せず）の収納および取り出しの際に、洗浄槽２を食器洗浄機本体１内から引き出す／押し込む動作を行う。洗浄槽２が食器洗浄機本体１に収納された状態（図３（ａ）の状態）では、移動ローラ７は固定レール８の奥の部分で支持され、固定ローラ９は移動レール６の手前の部分を支持する。洗浄槽２の重心は移動ローラ７と固定ローラ９の間に存在し、洗浄槽２の重さによって移動ローラ７は下側に押し付けられて、移動ローラ７は固定レール８の下部レール８ｂの上面に接している。このとき、移動レール６は水平状態となる。 An operation when the washing tub of the dishwasher configured as described above is pulled out / pushed in will be described. As in the first embodiment, when the tableware 3 (not shown) is stored in and taken out from the washing tub 2, the washing tub 2 is pulled out and pushed in from the tableware washing machine main body 1. In the state where the washing tub 2 is housed in the dishwasher main body 1 (the state shown in FIG. 3A), the moving roller 7 is supported by the inner part of the fixed rail 8, and the fixed roller 9 is in front of the moving rail 6. Support the part. The center of gravity of the cleaning tank 2 exists between the moving roller 7 and the fixed roller 9. The moving roller 7 is pressed downward by the weight of the cleaning tank 2, and the moving roller 7 is the upper surface of the lower rail 8 b of the fixed rail 8. Is in contact with At this time, the moving rail 6 is in a horizontal state.

一方、洗浄槽２が食器洗浄機本体１から引き出された状態（図３（ｂ）の状態）では、移動ローラ７は固定レール８の手前の部分で支持され、固定ローラ９は移動レール６の奥の部分を支持する。このとき、洗浄槽２の重心は、固定ローラ９よりも手前側に存在し、洗浄槽２の重さは固定ローラ９により支持される。そしてこのとき、移動レール６は洗浄槽２の重みによって撓む。その撓み角をαとする。また、移動ローラ７は固定ローラ９を支点として上面に押し付けられ、移動ローラ７は固定レール８の上部レール８ａの下面に接している。 On the other hand, in the state where the washing tub 2 is pulled out from the dishwasher main body 1 (the state shown in FIG. 3B), the moving roller 7 is supported by the portion in front of the fixed rail 8, and the fixed roller 9 is fixed to the moving rail 6. Support the inner part. At this time, the center of gravity of the cleaning tank 2 is present in front of the fixed roller 9, and the weight of the cleaning tank 2 is supported by the fixed roller 9. At this time, the moving rail 6 is bent by the weight of the cleaning tank 2. The bending angle is α. The moving roller 7 is pressed against the upper surface with the fixed roller 9 as a fulcrum, and the moving roller 7 is in contact with the lower surface of the upper rail 8 a of the fixed rail 8.

このように、固定レール８を引き出し側（食器洗浄機本体１の前面側）が低くなるように傾斜して取り付け、その傾斜角度は先に述べた値θとすることで、移動ローラ７の高さ位置の変動と、移動レール６の洗浄槽２の重みによる撓みを総合して、移動レール６が水平状態を常に保つことができ、そのため、洗浄槽２が食器洗浄機本体１内に収納され、移動ローラ７が下部レール８ｂの上面に接している状態でも、洗浄槽２が食器洗浄機本体１から引き出され、移動ローラ７が上部レール８ａの下面に接している状態でも、移動レール６は水平状態を保ち続けられ、移動レール６に固定された洗浄槽２の位置する高さは一定かつ水平状態を保てる。 In this way, the fixed rail 8 is mounted so as to be inclined so that the drawer side (the front side of the dishwasher body 1) is lowered, and the inclination angle is set to the value θ described above, so that the height of the moving roller 7 is increased. The moving rail 6 can always be kept in a horizontal state by combining the change in position and the deflection of the moving rail 6 due to the weight of the washing tank 2, so that the washing tank 2 is stored in the dishwasher body 1. Even in a state where the moving roller 7 is in contact with the upper surface of the lower rail 8b, the moving rail 6 remains in the state where the washing tub 2 is pulled out from the dishwasher body 1 and the moving roller 7 is in contact with the lower surface of the upper rail 8a. The height at which the washing tub 2 fixed to the moving rail 6 is kept constant can be kept constant and kept horizontal.

このように構成された食器洗浄機においては、洗浄槽２を食器洗浄機本体１から引き出した際に、収納された食器３の重さにより洗浄槽２が下がることがないので、洗浄槽２を食器洗浄機本体１に収納する際に洗浄槽２を押し込む操作力が大きくなるようなことはなく、操作性のよい食器洗浄機を実現することができる。 In the dishwasher configured as described above, when the washing tub 2 is pulled out from the tableware washing machine body 1, the washing tub 2 is not lowered due to the weight of the stored tableware 3, so When storing in the dishwasher main body 1, the operation force which pushes the washing tank 2 does not become large, and a dishwasher with good operability can be realized.

The fixed rail 8 has a substantially U-shaped cross section and is composed of an upper rail 8a and a lower rail 8b. A moving roller 7 is disposed between the upper rail 8a and the lower rail 8b. The moving rail 6 is formed by bending upward by a predetermined angle α from a portion located in the vicinity of the fixed roller 9 when the washing tub 2 is pulled out from the dishwasher body 1.

固定レール８は、引き出し側（食器洗浄機本体１の前面側）が低くなるよう傾斜させて食器洗浄機本体１の内部側面に取り付けられている。そして、その傾斜角度θは、θ＝ｔａｎ−１（ｙ／ｘ）で、ｙ＝Ａ−Ｂであり、Ａは固定レール８の上部レール８ａと下部レール８ｂの間隔、Ｂは移動ローラ７の直径、ｘは洗浄槽２が食器洗浄機本体１に収納された状態から手前に引き出された状態になるまでに移動ローラ７が移動する水平距離とする。   The fixed rail 8 is attached to the inner side surface of the dishwasher main body 1 so that the drawer side (the front side of the dishwasher main body 1) is lowered. The inclination angle θ is θ = tan−1 (y / x), y = A−B, A is the distance between the upper rail 8 a and the lower rail 8 b of the fixed rail 8, and B is the moving roller 7. The diameter x is a horizontal distance that the moving roller 7 moves from the state in which the washing tub 2 is housed in the dishwasher main body 1 to the state in which the washing tank 2 is pulled out.

このように構成された食器洗浄機の洗浄槽の引き出す／押し込むときの動作について説明する。上記実施の形態1と同様に、洗浄槽２内への食器３（図示せず）の収納および取り出しの際に、洗浄槽２を食器洗浄機本体１内から引き出す／押し込む動作を行う。洗浄槽２が食器洗浄機本体１に収納された状態（図４（ａ）の状態）では、移動ローラ７は固定レール８の奥の部分で支持され、固定ローラ９は移動レール６の手前の部分を支持する。洗浄槽２の重心は移動ローラ７と固定ローラ９の間に存在し、洗浄槽２の重さによって移動ローラ７は下側に押し付けられて、移動ローラ７は固定レール８の下部レール８ｂの上面に接している。   An operation when the washing tub of the dishwasher configured as described above is pulled out / pushed in will be described. As in the first embodiment, when the tableware 3 (not shown) is stored in and taken out from the washing tub 2, the washing tub 2 is pulled out and pushed in from the tableware washing machine main body 1. In the state where the washing tub 2 is housed in the dishwasher main body 1 (the state shown in FIG. 4A), the moving roller 7 is supported at the back of the fixed rail 8, and the fixed roller 9 is in front of the moving rail 6. Support the part. The center of gravity of the cleaning tank 2 exists between the moving roller 7 and the fixed roller 9. The moving roller 7 is pressed downward by the weight of the cleaning tank 2, and the moving roller 7 is the upper surface of the lower rail 8 b of the fixed rail 8. Is in contact with

一方、洗浄槽２が食器洗浄機本体１から引き出された状態（図４（ｂ）の状態）では、移動ローラ７は固定レール８の手前の部分で支持され、固定ローラ９は移動レール６の奥の部分を支持する。このとき、洗浄槽２の重心は、固定ローラ９よりも手前側に存在し、洗浄槽２の重さは固定ローラ９により支持される。そして、このとき、移動レール６は洗浄槽２の重みによって撓む。その撓み角を所定角度αとしている。また、移動ローラ７は固定ローラ９を支点として上面に押し付けられ、移動ローラ７は固定レール８の上部レール８ａの下面に接している。   On the other hand, in the state where the washing tub 2 is pulled out from the dishwasher main body 1 (the state shown in FIG. 4B), the moving roller 7 is supported by the portion in front of the fixed rail 8, and the fixed roller 9 is fixed to the moving rail 6. Support the inner part. At this time, the center of gravity of the cleaning tank 2 is present in front of the fixed roller 9, and the weight of the cleaning tank 2 is supported by the fixed roller 9. At this time, the moving rail 6 is bent by the weight of the cleaning tank 2. The deflection angle is a predetermined angle α. The moving roller 7 is pressed against the upper surface with the fixed roller 9 as a fulcrum, and the moving roller 7 is in contact with the lower surface of the upper rail 8 a of the fixed rail 8.

このようにして、固定レール８を引き出し側（食器洗浄機本体１の前面側）が低くなるよう傾斜して取り付け、その傾斜角度を上述した値θとし、洗浄槽２を食器洗浄機本体１に収納した状態のときの移動レール６の固定ローラ９から前方を角度αだけ上方に曲げることで、移動レール６が洗浄槽２の重みにより角度αだけ撓み、移動レール６は直線状となり、移動ローラ７の高さと移動レール６の撓みを総合して、移動レール６を水平状態に保つことができる。   In this way, the fixed rail 8 is attached so that the drawer side (front side of the dishwasher main body 1) is lowered, the inclination angle is set to the value θ described above, and the washing tub 2 is attached to the dishwasher main body 1. By bending the front of the moving rail 6 from the fixed roller 9 in the retracted state upward by an angle α, the moving rail 6 is bent by the angle α due to the weight of the cleaning tank 2, and the moving rail 6 becomes linear, and the moving roller By combining the height of 7 and the bending of the moving rail 6, the moving rail 6 can be kept in a horizontal state.

このように構成された食器洗浄機においては、洗浄槽２を食器洗浄機本体１から引き出した状態で、移動レール６が水平状態となるため、洗浄槽２を食器洗浄機本体１内に収納する際に、洗浄槽２を押し込む操作力が大きくなるようなことはなく、操作性のよい食器洗浄機を実現することができる。 In the dishwasher configured as described above, since the moving rail 6 is in a horizontal state in a state where the washing tub 2 is pulled out from the dishwasher main body 1, the washing tub 2 is stored in the dishwasher main body 1. In this case, the operation force for pushing the washing tub 2 is not increased, and a dishwasher with good operability can be realized.
