JP 11-142861 A

ところで、日本の狭い台所に設置される食器洗い機1においては、その外形寸法を変えずに食器かご9に収容する食器類7の数を増すことが求められており、そのため洗浄槽2内の空いている空間に、いかに食器類7を入れるかが重要な課題となっている。その方法の一つとして、洗浄槽2の内底面と食器かご9との間の洗浄ノズル6が配設されている空間の上下隙間を狭くし、食器かご9の上方空間を大きくすることが考えられる。   By the way, in the dishwasher 1 installed in a narrow kitchen in Japan, it is required to increase the number of tableware 7 accommodated in the tableware basket 9 without changing the external dimensions. How to put tableware 7 into the space is an important issue. As one of the methods, it is considered to narrow the space above and below the space in which the cleaning nozzle 6 between the inner bottom surface of the cleaning tank 2 and the tableware basket 9 is arranged, and to enlarge the space above the tableware basket 9. It is done.

本発明は、上記課題を解決するもので、洗浄槽内の空間を有効活用し、より多くの食器類を収容可能として使い勝手を向上した食器洗い機の提供を目的としている。   SUMMARY OF THE INVENTION The present invention solves the above-described problems, and an object thereof is to provide a dishwasher that can effectively use a space in a washing tank and can accommodate more tableware and has improved usability.

本発明の食器洗い機は、食器類を配置し洗浄する洗浄槽と、洗浄槽の内部に設けられて洗浄水を噴射する1つ以上の回転洗浄ノズルとを備え、回転洗浄ノズルは、回転軸部と水平通水路部とを有しかつ回転軸部の上端が水平通水路の下面よりも上方に位置するように形成したものである。   The dishwasher of the present invention includes a washing tub in which dishes are arranged and washed, and one or more rotary washing nozzles that are provided inside the washing tub and inject washing water. And a horizontal water passage portion, and the upper end of the rotary shaft portion is formed above the lower surface of the horizontal water passage.

洗浄槽の内底面と食器かごの下端との間の上下隙間は、回転洗浄ノズルの回転軸部の高さと、水平通水路部高さと、洗浄ノズルの噴射回転時の上下がたつき及び傾斜時の端部高さと、食器かごのたわみ量などから決まるものである。そして、回転軸部の高さは回転洗浄ノズルを安定的に回転自在に支持するために最低必要高さが決まり、洗浄ノズルの水平通水路高さは洗浄水の流量と異物つまり対策から最低必要高さが決まり、食器かごのたわみ量も構成上最低必要高さが決まり、洗浄ノズルの噴射回転時の上下がたつきは異物つまり対策から最低必要高さが決まる。   The vertical gap between the inner bottom of the washing tub and the lower end of the tableware basket is the height of the rotary shaft of the rotary washing nozzle, the height of the horizontal water passage, and the vertical swing and inclination of the washing nozzle during jet rotation. This is determined by the height of the edge of the bowl and the amount of deflection of the tableware basket. The height of the rotary shaft is determined to be the minimum required to stably support the rotary cleaning nozzle so that it can rotate freely. The horizontal water passage height of the cleaning nozzle is the minimum required from the flow rate of cleaning water and foreign matter, that is, countermeasures. The height is determined, the amount of deflection of the tableware basket is determined in terms of the configuration, and the minimum required height is determined from foreign matters, that is, countermeasures, for the vertical fluctuation at the time of the jet nozzle rotation.

上記の構成によれば、上記のような条件下でも、回転洗浄ノズルの回転軸部の高さ寸法と水平通水路部高さを確保しながら、回転軸部の下端に対して水平通水路部上端の高さ位置を低くすることができ、その分洗浄槽内空間の内、洗浄槽の内底面、すなわち回転洗浄ノズルの下端と食器かごの下端との間の上下隙間を狭くし、食器かごの上方空間を大きくすることができ、より多くの食器類が収容可能となり、使い勝手を向上することができる。   According to the above configuration, the horizontal water passage portion with respect to the lower end of the rotation shaft portion is secured while ensuring the height dimension of the rotation shaft portion of the rotary cleaning nozzle and the height of the horizontal water passage portion even under the above-described conditions. The height position of the upper end can be lowered, and the upper and lower clearances between the lower end of the cleaning tank, that is, the lower end of the rotary cleaning nozzle and the lower end of the tableware basket, are narrowed accordingly. The space above can be increased, and more tableware can be accommodated, improving usability.

また、水平通水路部の端部を押し下げたときに、反対側の端部の高さが水平通水路部上面の回転軸上方と略同じ高さになるように、洗浄槽に設けた軸受け部と回転洗浄ノズルの回転軸部との隙間を設定すると、回転洗浄ノズル傾斜時の端部高さが低く規制されるため、洗浄槽の内底面、すなわち回転洗浄ノズルの下端と食器かごの下端との間の上下隙間を狭くし、食器かごの上方空間を大きくすることができ、洗浄槽内の空間をより有効に利用でき、より多くの食器類を収容可能となり、使い勝手を向上することができる。   Also, when the end of the horizontal water passage is pushed down, the bearing provided in the washing tub is such that the height of the opposite end is substantially the same height as above the rotation axis on the upper surface of the horizontal water passage. If the clearance between the rotary cleaning nozzle and the rotary shaft of the rotary cleaning nozzle is set, the end height when the rotary cleaning nozzle is tilted is restricted to a low level, so the inner bottom surface of the cleaning tank, that is, the lower end of the rotary cleaning nozzle and the lower end of the tableware basket The space above and below the table can be narrowed, the space above the tableware basket can be increased, the space inside the washing tub can be used more effectively, more tableware can be accommodated, and usability can be improved. .

本発明の食器洗い機は、回転洗浄ノズルの回転軸部の上端を水平通水路の下面よりも上方に位置するように形成したことにより、洗浄槽内空間の内、洗浄ノズルの下端と食器かごの下端との間の上下隙間を狭くし、食器かごの上方空間を大きくすることができ、より多くの食器類を収容可能として使い勝手を向上することができる。   In the dishwasher of the present invention, the upper end of the rotary shaft of the rotary cleaning nozzle is formed so as to be positioned above the lower surface of the horizontal water passage. The upper and lower gaps between the lower ends can be narrowed, the upper space of the tableware basket can be increased, and more tableware can be accommodated to improve usability.

以下、本発明の食器洗い機の一実施形態について、図1〜図3を参照しながら説明する。なお、図4を参照して説明した従来例の食器洗い機と同じ構成要素については同一参照符号を付して説明を省略する。また、本発明は本実施形態によって限定されるものではない。   Hereinafter, an embodiment of the dishwasher of the present invention will be described with reference to FIGS. In addition, about the same component as the dishwasher of the prior art example demonstrated with reference to FIG. 4, the same referential mark is attached | subjected and description is abbreviate | omitted. The present invention is not limited to the present embodiment.

本実施形態の食器洗い機1において、図1〜図3に示すように、回転洗浄ノズル18は、回転軸部19と水平通水路部20からなり、洗浄槽2の内底面上に設けられた軸受け部21に回転自在に軸支されている。洗浄ポンプ5より吐出された洗浄水は、回転軸部19下端の開口部22より流入し、回転軸部19内を通り、水平通水路部20を通って複数の噴射口23より食器類7に向かって噴出する。   In the dishwasher 1 of the present embodiment, as shown in FIGS. 1 to 3, the rotary cleaning nozzle 18 includes a rotary shaft portion 19 and a horizontal water passage portion 20, and is a bearing provided on the inner bottom surface of the cleaning tank 2. The part 21 is rotatably supported. The cleaning water discharged from the cleaning pump 5 flows in from the opening 22 at the lower end of the rotating shaft portion 19, passes through the rotating shaft portion 19, passes through the horizontal water passage portion 20, and is supplied to the dishes 7 from the plurality of injection ports 23. It spouts toward.

回転洗浄ノズル18は、図2、図3に示すように、回転軸部19の上端24が水平通水路部20の下面25よりも上方に位置するように形成されている。また、回転洗浄ノズル18が傾斜したときに、その端部26が水平通水路部20の最も高い部位、すなわち水平通水路部20上面の回転軸部19上方部位27と略同じ高さになるように、回転軸部19と軸受け部21との隙間が設定されている(例えば、片側0.25mm)。   As shown in FIGS. 2 and 3, the rotary cleaning nozzle 18 is formed such that the upper end 24 of the rotary shaft portion 19 is located above the lower surface 25 of the horizontal water passage portion 20. Further, when the rotary cleaning nozzle 18 is inclined, the end 26 thereof is substantially the same height as the highest portion of the horizontal water passage portion 20, that is, the portion 27 above the rotation shaft portion 19 on the upper surface of the horizontal water passage portion 20. Further, a gap between the rotary shaft portion 19 and the bearing portion 21 is set (for example, 0.25 mm on one side).

以上の本実施形態の構成によれば、回転洗浄ノズル18の回転軸部19の高さ寸法と水平通水路部20高さを確保しながら、回転軸部19の下端、すなわち洗浄槽2の内底面に対して水平通水路部20上端の高さ位置を低くすることができ、その分洗浄槽2の内底面と食器かご9の下端との間の上下隙間を狭くし、食器かご9の上方空間を大きくすることができ、より多くの食器類を収容可能として使い勝手を向上することができる。   According to the configuration of the present embodiment described above, while ensuring the height dimension of the rotary shaft portion 19 of the rotary cleaning nozzle 18 and the height of the horizontal water passage portion 20, the lower end of the rotary shaft portion 19, that is, the inside of the cleaning tank 2. The height position of the upper end of the horizontal water passage portion 20 with respect to the bottom surface can be lowered, and the vertical gap between the inner bottom surface of the washing tub 2 and the lower end of the tableware basket 9 is narrowed accordingly, The space can be enlarged, and the convenience of use can be improved as more tableware can be accommodated.

また、回転洗浄ノズル18が傾斜した時の端部26の高さが水平通水路部20の最も高い部位、すなわち水平通水路部20上面の回転軸部19上方部位27より高くならないようにしたことにより、回転洗浄ノズル18の下端、すなわち洗浄槽2の内底面と食器かご9の下端のと間の上下隙間を従来技術によるものよりも狭くすることができ、これにより食器かご9の位置を下げることができるので、洗浄槽2内の空間をより有効に利用でき、より多くの食器類7を一度に洗浄することができる。   Further, the height of the end portion 26 when the rotary cleaning nozzle 18 is inclined is set not to be higher than the highest portion of the horizontal water passage portion 20, that is, the portion 27 above the rotation shaft portion 19 on the upper surface of the horizontal water passage portion 20. Thus, the upper and lower gaps between the lower end of the rotary cleaning nozzle 18, that is, the inner bottom surface of the cleaning tank 2 and the lower end of the tableware basket 9 can be made narrower than that of the prior art, thereby lowering the position of the tableware basket 9. Therefore, the space in the washing tank 2 can be used more effectively, and more dishes 7 can be washed at a time.

本発明の食器洗い機は、回転洗浄ノズルをその回転軸部の上端が水平通水路の下面よりも上方に位置するように形成したことにより、本体を大きくすることなく、より多くの食器類を洗浄可能でかつ使い勝手が向上するため、一般家庭用の食器洗い機等として有用である。   In the dishwasher of the present invention, the rotary washing nozzle is formed so that the upper end of the rotary shaft portion is positioned above the lower surface of the horizontal water passage, so that more dishes can be washed without enlarging the main body. Since it is possible and improves usability, it is useful as a dishwasher for general households.
