Description
本発明は、食器の洗浄を行う食器洗い機に関するものである。 The present invention relates to a dishwasher for washing dishes.
従来、導水経路を切換えて洗浄水を噴射する一般的な食器洗い機は、図15のような構成をしている。以下、その構成について説明する。 Conventionally, a general dishwasher that jets washing water by switching the water conveyance path has a configuration as shown in FIG. Hereinafter, the configuration will be described.
図に示すように、洗浄槽51は底部に洗浄水を貯留し内部にカゴ56にセットされた被洗浄物を収納する。洗浄ポンプ53は洗浄槽51の下方に設けられたモータ52を駆動源として洗浄槽51内の被洗浄物に洗浄水を噴射する。洗浄ノズル55は洗浄槽51の底部中央から突出した2重構造のパイプ部材54に回転自在に支持されている。前記洗浄ノズル55はその内部を仕切板57により第1の洗浄水流路58と第2の洗浄水流路59に分けられている。前記パイプ部材54の内中空部60が、第1の洗浄水流路58に連絡され、また、外中空部61が第2の洗浄水流路59に連絡されており、ソレノイド62で駆動される切換弁63により洗浄ポンプ53から噴射される洗浄水を前記洗浄水流路58、59へ切換えるものである。 As shown in the figure, the cleaning tank 51 stores cleaning water at the bottom and stores an object to be cleaned set in the basket 56 inside. The cleaning pump 53 injects cleaning water onto an object to be cleaned in the cleaning tank 51 by using a motor 52 provided below the cleaning tank 51 as a driving source. The cleaning nozzle 55 is rotatably supported by a double-structure pipe member 54 protruding from the center of the bottom of the cleaning tank 51. The inside of the washing nozzle 55 is divided into a first washing water channel 58 and a second washing water channel 59 by a partition plate 57. An inner hollow portion 60 of the pipe member 54 communicates with the first wash water flow path 58, and an outer hollow portion 61 communicates with the second wash water flow path 59, and is a switching valve driven by a solenoid 62. The washing water sprayed from the washing pump 53 by 63 is switched to the washing water flow paths 58 and 59.
洗浄槽51内の洗浄水は、洗浄ポンプ53により洗浄ノズル55に送られるが、途中、切換弁63により第1の洗浄水流路58と第2の洗浄水流路59に分かれ、洗浄およびすすぎ工程中はいずれか一方が必ず閉められ、一定時間毎にソレノイド62を駆動し切換弁63を動かして第1および第2の洗浄水流路58、59の入口64、65を交互に開放する。洗浄ならびにすすぎ工程中において、第1および第2の洗浄水流路58、59より、交互に洗浄水を逆の噴射角を有して噴射すれば、洗浄ノズル55は、両方向に回転し、被洗浄物に対して両面から洗浄水が入射することになり、被洗浄物全体を均等に効率よく洗浄ならびにすすぐことができる(例えば、特許文献1参照)。
しかしながら、上記従来の食器洗い機では、第1および第2の洗浄水流路58、59を切換える切換弁63や洗浄ポンプ43が洗浄ノズル55の下部に配置されることで、食器洗い機本体の高さが高くなり、吊り戸棚が設けられているシステムキツチン上への設置性が悪くなる。また、設置性を確保すると、洗浄槽51内の高さが低くなり、被洗浄物を収納する容量が小さくなる等食器洗浄に必要な容積が十分に確保できないという課題を有していた。 However, in the above conventional dishwasher, the switching valve 63 and the washing pump 43 for switching the first and second washing water flow paths 58 and 59 are arranged below the washing nozzle 55, so that the height of the dishwasher main body is increased. It becomes high and the installation property on the system kitine where the hanging cupboard is provided is deteriorated. Further, if the installation property is secured, there is a problem that the volume required for dish washing cannot be sufficiently secured, for example, the height in the washing tank 51 becomes low and the capacity for storing the object to be washed becomes small.
本発明は、上記従来の課題を解決するもので、設置性と洗浄槽の被洗浄物をセットできる容量を確保することを目的とする。 This invention solves the said conventional subject, and aims at ensuring the capacity | capacitance which can set the installation property and the to-be-cleaned thing of a washing tank.

The rotary cleaning means is disposed at a position away from the bearing portion in the horizontal direction.
これによって、複数の噴出口から効率よく洗浄水を被洗浄物に入射することができるとともに、回転洗浄手段の洗浄導水部に対して洗浄水を側方から供給することができ、回転洗浄手段を低い位置に配設することができ、被洗浄物がセットできる容量の確保と設置性を両立させることができる。 Accordingly, the cleaning water can be efficiently incident on the object to be cleaned from the plurality of jet nozzles, and the cleaning water can be supplied from the side to the cleaning water guide portion of the rotating cleaning unit. It can be disposed at a low position, and it is possible to achieve both the securing of the capacity to set the object to be cleaned and the installation property.

以上のように構成された食器洗い機について、以下その動作、作用を説明する。食器等の被洗浄物13を食器かご3にセットして洗浄槽2に収納し、洗剤を投入した後、蓋体により本体1の開口部を閉塞し、運転を開始する。被洗浄物13の汚れを落とす洗浄工程、付着した洗剤や残菜を流すすすぎ工程、そして被洗浄物13に付着している水適を乾燥させる乾燥工程の順に実行する。 About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. An object to be cleaned 13 such as tableware is set in the tableware basket 3 and stored in the cleaning tub 2, and after the detergent is put in, the opening of the main body 1 is closed with a lid and the operation is started. The cleaning process is performed in order of cleaning the object 13 to be cleaned, the rinsing process in which the attached detergent and leftovers are poured, and the drying process for drying the water adhering to the object 13 to be cleaned.
まず、洗浄工程は、制御手段14により、給水弁を動作して所定量の洗浄水を洗浄槽2に給水する。この際、洗浄槽2内に設けたヒータ(加熱手段)15は通電され、洗浄水は加温される。次に、洗浄ポンプ4により洗浄水を加圧し、分水手段5に供給する。分水手段5内の弁体7は、制御手段14により所定の時間で、複数の吐出経路の中で、洗浄水を流送する吐出経路6のみを開口し、残りの吐出経路6は閉じる。開口された吐出経路6へ流送された洗浄水は、洗浄導水部11へ流入し整流され、回転洗浄手段8の導水経路9に流入する。導水経路9に設けられた噴出口10から洗浄水が被洗浄物13に噴出される。 First, in the cleaning process, the control unit 14 operates the water supply valve to supply a predetermined amount of cleaning water to the cleaning tank 2.

Thus, the wash water that has flowed in from the outer peripheral side of the cleaning water guiding portion 18 flows along the path, changes the direction of the flow in the straight portion, and is rectified, thereby uniformly passing the outer peripheral side path 21 in the vertical direction. The washing water can be efficiently sent to the water flow path 9 of the flow and rotary washing means 8.
したがって、洗浄導水部18には、水平横方向に洗浄水が流入し、回転洗浄手段8へ軸受19側垂直方向に洗浄水を流送することで、分水手段5や洗浄ポンプ4を、本体1の設置面に対して水平方向に離して配置でき、食洗機本体1が垂直方向に高くなることなく、本体1の設置性および被洗浄物13のセット性を確保できる。 Accordingly, the cleaning water flows into the cleaning water guiding portion 18 in the horizontal and horizontal directions, and the cleaning water is flowed to the rotary cleaning means 8 in the vertical direction on the bearing 19 side, so that the water distribution means 5 and the cleaning pump 4 are connected to the main body. The installation surface of the main body 1 and the setting property of the object to be cleaned 13 can be secured without the dishwasher main body 1 being raised in the vertical direction.
また、図4に示すように、分水手段5の複数の吐出経路6を水平方向に並べて形成することで、複数の吐出経路6を同じ高さに配設することができ、吐出経路6が上下に分離することがなく、分水手段5、吐出経路6、洗浄導水部18といった分水機構部の設置による高さ方向のスペース増加を低減でき、本体1の設置性および被洗浄物のセット性を確保できる。 Further, as shown in FIG. 4, the plurality of discharge paths 6 of the water distribution means 5 are formed side by side in the horizontal direction, so that the plurality of discharge paths 6 can be arranged at the same height. The space increase in the height direction due to the installation of the water diversion mechanism such as the water diversion means 5, the discharge path 6, and the washing water guiding portion 18 can be reduced without being separated into the upper and lower sides. Can be secured.
また、分水手段5の複数の吐出経路6は、その高さ関係において、図5に示すように、洗浄導水部18の内周側の経路20と連通する吐出経路22が、外周側の経路21と連通する吐出経路23の下部に位置し、吐出経路22と連通する洗浄導水部18の洗浄導水部流入口24は、洗浄導水部18の下方に設けられている。洗浄水が吐出経路から洗浄導水部18に流入する際に、吐出経路22が、吐出経路23を遮って横断することがないので、吐出経路23を流れる洗浄水は、圧力損失を低減でき、エネルギ効率よく洗浄できるものである。 Further, as shown in FIG. 5, the plurality of discharge paths 6 of the water distribution means 5 have discharge paths 22 communicating with the inner peripheral path 20 of the cleaning water guiding section 18, as shown in FIG. 5. The cleaning water inlet 24 of the cleaning water guide 18 that is positioned below the discharge path 23 that communicates with the discharge path 22 and that communicates with the discharge path 22 is provided below the cleaning water guide 18. When the cleaning water flows from the discharge path into the cleaning conduit 18, the discharge path 22 does not cross the discharge path 23, so that the cleaning water flowing through the discharge path 23 can reduce pressure loss and energy. It can be cleaned efficiently.
また、吐出経路22は、水平横方向から垂直上方に流路を変化させることで、洗浄導水部流入口24と連通でき、内周側の経路20のストレート部を長くでき、洗浄水の流れ分布を経路に対して均一にでき、洗浄水のエネルギロスを防げるものである。 Further, the discharge path 22 can be communicated with the cleaning water introduction section inlet 24 by changing the flow path from the horizontal lateral direction to the vertical upper direction, the straight section of the inner peripheral path 20 can be lengthened, and the flow distribution of the cleaning water. Can be made uniform with respect to the path, and energy loss of the washing water can be prevented.
また、図6に示すように、分水手段5の複数の吐出経路6は、その高さ関係において、洗浄導水部25の外周部側と連通する吐出経路29を、内周部側と連通する吐出経路28の下部に設けてもよい。吐出経路29から流送されてきた洗浄水は、洗浄導水部25の外周側の経路27で、内周側の経路26を中心にして回転する方向に流れた後、もしくは回転しながら上方に傾斜して流がれる。その後、ストレート部の経路を通って、回転洗浄手段8の導水経路9に流入される。 Further, as shown in FIG. 6, the plurality of discharge paths 6 of the water distribution means 5 communicate with the inner peripheral part side of the discharge path 29 that communicates with the outer peripheral part side of the cleaning water guiding part 25 in the height relationship. You may provide in the lower part of the discharge path | route 28. FIG. The cleaning water sent from the discharge path 29 flows in the direction of rotation around the inner periphery side path 26 in the outer periphery side path 27 of the cleaning water guide section 25, or tilts upward while rotating. And then flow. Thereafter, the water flows into the water guide path 9 of the rotary cleaning means 8 through the straight path.
したがって、洗浄導水部25の外周側の経路27が回転洗浄手段8の導水経路9に流入するまでのストレート部の距離を確保でき、洗浄水がより整流されるので、外周側の経路27内における洗浄水の圧力分布の均一性が改善され、経路内での圧力損失を低減することができる。したがって、本体1の設置性および被洗浄物13のセット性を確保でき、洗浄効率が向上するものである。 Therefore, the distance of the straight part until the outer periphery side path 27 of the cleaning water guide portion 25 flows into the water guide path 9 of the rotary cleaning means 8 can be secured, and the cleaning water is more rectified. The uniformity of the pressure distribution of the washing water is improved, and the pressure loss in the path can be reduced. Therefore, the installation property of the main body 1 and the setting property of the article to be cleaned 13 can be ensured, and the cleaning efficiency is improved.
また、図7に示すように、分水手段5の吐出経路6と連通する少なくとも2つの吐出口30を、同じ高さで水平方向に並列配置してもよい。吐出口30が上下方向に分離することなく、吐出経路6と連通することで、分水手段5と吐出経路6、洗浄導水部18を含む分水機構部の設置により、本体1の高さが高くなることなく、本体1の設置性と被洗浄物13のセット性を確保するとともに、効率よく洗浄することができるものである。 In addition, as shown in FIG. 7, at least two discharge ports 30 communicating with the discharge path 6 of the water distribution means 5 may be arranged in parallel in the horizontal direction at the same height. The discharge port 30 communicates with the discharge path 6 without being separated in the vertical direction, so that the height of the main body 1 is increased by installing the water distribution means 5, the discharge path 6, and the water diversion mechanism including the cleaning water guide 18. Without becoming high, while ensuring the installation property of the main body 1 and the setting property of the article 13 to be cleaned, it can be efficiently cleaned.
(実施の形態3)
図8に示すように、分水手段5の吐出口31は、洗浄導水部32の流入口33と同じ高さか、もしくはそれより低い位置に設けられ、分水手段5の流入口34は、洗浄ポンプ4の吐出口35と同じ高さか、もしくはそれより高い位置に設けられている。洗浄工程、すすぎ工程の運転の後で、洗浄水を入れ換えるために、排水ポンプ等で排水する。排水時に水の滞留部ができると、排水されずに残水として内部に残ってしまい、次行程での給水時に残水が給水されたきれいな水と混じってしまうことで、洗浄水の濁度が低下してしまう。
(Embodiment 3)
As shown in FIG. 8, the discharge port 31 of the water distribution means 5 is provided at the same height as or lower than the inlet 33 of the cleaning water guiding section 32, and the inlet 34 of the water distribution means 5 is cleaned. It is provided at the same height as the discharge port 35 of the pump 4 or at a position higher than that. After the washing process and the rinsing process, in order to replace the washing water, the water is drained by a drain pump or the like. If there is a water retention part during drainage, it will remain in the interior as residual water without draining, and the remaining water will be mixed with clean water supplied during the next stroke, resulting in turbidity of the washing water. It will decline.
排水時には、洗浄槽2の中の洗浄水は、排水口から排水されるが、その一部、分水手段5や吐出経路6、洗浄導水部32、回転洗浄手段8等の洗浄水は、洗浄時とは、逆方向に、洗浄導水部32から吐出経路6を通って、分水手段5から排水口に流れ、排水される。その際、本実施の形態では、排水される方向に常に同じ高さか下方に洗浄導水部32、吐出経路6、分水手段5を配置しているので、残水が滞留しない。したがって、排水後、洗浄槽2に残水が少なくなることで、次工程もしくは次使用時、給水による洗浄水の濁度が小さくなり、洗浄性能、すすぎ性能が向上するものである。 At the time of drainage, the washing water in the washing tank 2 is drained from the drain outlet, but some of the washing water from the water distribution means 5, the discharge path 6, the washing water guiding section 32, the rotating washing means 8, etc. is washed. In the opposite direction, the water flows from the washing water guiding section 32 through the discharge path 6 to the drain outlet from the water diversion means 5 and is drained. At this time, in the present embodiment, since the cleaning water guide section 32, the discharge path 6, and the water distribution means 5 are always arranged at the same height or downward in the direction of drainage, residual water does not stay. Therefore, after draining, the remaining water in the washing tank 2 is reduced, so that the turbidity of the washing water by water supply is reduced in the next process or next use, and the washing performance and the rinsing performance are improved.

図9は、分水手段5から回転洗浄手段8までの洗浄水の流路構成を示す。分水手段5は、複数の吐出経路6を切換える弁体7を有し、弁体7は、洗浄ポンプ4の運転、停止により、上下方向に動作しながら回転し、吐出経路6への洗浄水の供給を切換える構成で、洗浄導水部11の流入口36は、分水手段5の吐出口37より低い位置に設けている。
(Embodiment 4)
FIG. 9 shows the flow path configuration of the washing water from the water distribution means 5 to the rotary washing means 8. The water distribution means 5 has a valve body 7 that switches a plurality of discharge paths 6, and the valve body 7 rotates while operating in the vertical direction by the operation and stop of the cleaning pump 4, and the cleaning water to the discharge path 6 The inlet 36 of the cleaning water guiding section 11 is provided at a position lower than the discharge port 37 of the water distribution means 5.
図10〜図13は、分水手段5の詳細図である。図10は、弁体7の開口部38を示す平面図である。図11に示したように、洗浄ポンプ4で加圧された洗浄水が流入する分水手段の流入口39と複数の吐出経路6に各々連通した複数の吐出口40を有するケーシング41と、吐出口40の少なくとも1つと対向するように開口部38を設けるとともに、開口部38が対向する吐出口40が切換わるようにケーシング41内で弁体7が回転動作する。 10 to 13 are detailed views of the water distribution means 5. FIG. 10 is a plan view showing the opening 38 of the valve body 7. As shown in FIG. 11, a casing 41 having a plurality of discharge ports 40 respectively connected to a plurality of discharge ports 6 and an inlet 39 of a diversion means into which wash water pressurized by the cleaning pump 4 flows, The valve body 7 rotates in the casing 41 so that the opening 38 is provided so as to face at least one of the outlets 40 and the discharge port 40 facing the opening 38 is switched.
以下その動作、作用を説明する。洗浄ポンプ4が運転すると洗浄水が分水手段5の流入口39より流入する。吐出口40に対して進退自在な弁体7は、中央が貫通しており、弁体7の進退を案内する支持部42に沿って、洗浄水の圧力により弁体7を上方に押し上げる。 The operation and action will be described below. When the cleaning pump 4 is operated, cleaning water flows from the inlet 39 of the water dividing means 5. The valve body 7 that can move forward and backward with respect to the discharge port 40 penetrates the center, and pushes the valve body 7 upward by the pressure of the washing water along the support portion 42 that guides the advancement and retraction of the valve body 7.
その際、弁体7は上部係合部43の傾斜に従って、回転及び略直動を伴った動作で上昇し、所定の吐出口40が開口するように、弁体7の開口部38と所定の吐出口40が一致する位置で固定される(図12)。その他の吐出口40は、弁体7により密閉塞される。 At that time, the valve body 7 rises in accordance with the inclination of the upper engagement portion 43 by an operation accompanied by rotation and substantially linear movement, and the opening portion 38 of the valve body 7 and the predetermined portion are opened so that the predetermined discharge port 40 is opened. The discharge ports 40 are fixed at the matching positions (FIG. 12). The other discharge ports 40 are tightly closed by the valve body 7.
続いて、洗浄ポンプ4を一旦停止すると、弁体7を下方から押し上げていた水圧が作用しなくなることから、弁体7は支持部42に沿って、その自重で降下するが、この際、下部係合部44の傾斜に従って回転しながら降下し、所定位置で停止する。再び、洗浄ポンプ4を運転すると、上部係合部43の傾斜に係合され、弁体7は回転しながら上昇し、弁体7の開口部38と、次の吐出口とが連通されることで、吐出経路6を切換えることができる。 Subsequently, once the washing pump 4 is stopped, the water pressure that pushes up the valve body 7 from below does not act, so the valve body 7 descends along its supporting portion 42 due to its own weight. It descends while rotating according to the inclination of the engaging portion 44 and stops at a predetermined position. When the washing pump 4 is operated again, it is engaged with the inclination of the upper engaging portion 43, the valve body 7 is raised while rotating, and the opening 38 of the valve body 7 and the next discharge port are communicated with each other. Thus, the discharge path 6 can be switched.
なお、この係合部43、44に関しては螺旋形や三角などの形状に限定するものではなく、洗浄ポンプ4を断続的に運転する際に、洗浄ポンプ4を運転中に所定の吐出口40と弁体7の開口部38が一致すればよい。また、弁体7の外周部など、係合部の位置を限定するものでもない。 The engaging portions 43 and 44 are not limited to a shape such as a spiral shape or a triangular shape. When the cleaning pump 4 is intermittently operated, the predetermined discharge port 40 and The opening 38 of the valve body 7 should just correspond. Further, the position of the engaging portion such as the outer peripheral portion of the valve body 7 is not limited.
このように、専用の電動駆動部を設けなくても、洗浄ポンプ4の運転、停止で、弁体7を切換えることができ、吐出経路6を切換える弁体7が回転しながら上下方向に動くスペースを確保しても、洗浄導水部の流入口36を分水手段の流出口37より、本体の設置面に対して垂直方向に低い位置に設けることで、分水手段5と洗浄導水部11の設置高さをほぼ同一にでき、食器洗い機本体1の設置性、及び被洗浄物13のセット性を確保でき、更に、分水手段5によって、噴射角度、噴射位置等異なる噴射口を有する回転洗浄手段8の導水経路9を切換えることができ、効率よく洗浄できる。 In this way, the valve body 7 can be switched by operating and stopping the cleaning pump 4 without providing a dedicated electric drive unit, and the valve body 7 that switches the discharge path 6 moves in the vertical direction while rotating. However, by providing the inlet 36 of the cleaning water guide portion at a position lower than the outlet 37 of the water distribution means in a direction perpendicular to the installation surface of the main body, the water distribution means 5 and the cleaning water guide portion 11 are provided. The installation height can be made almost the same, the installation property of the dishwasher main body 1 and the setting property of the object to be cleaned 13 can be secured, and further, the water washing means 5 has a rotary cleaning having different injection ports such as the injection angle and the injection position. The water guide path 9 of the means 8 can be switched and can be washed efficiently.
(実施の形態5)
図14に示すように、回転洗浄手段8の導水経路9が2つの場合、第1の導水経路45と第2の導水経路46は、回転洗浄手段8内で仕切られ、第1の導水経路45もしくは第2の導水経路46には、回転洗浄手段8が右回転に回転するように、推進方向に対して反対方向に噴射角度を有する少なくとも1つの噴出口を設けている。また、一方の第1の導水経路45もしくは第2の導水経路46は、回転洗浄手段8が左回転するように、噴出口を設けているものである。
(Embodiment 5)
As shown in FIG. 14, when there are two water conveyance paths 9 of the rotary cleaning means 8, the first water conveyance path 45 and the second water conveyance path 46 are partitioned within the rotary cleaning means 8, and the first water conveyance path 45. Alternatively, the second water guide path 46 is provided with at least one jet outlet having an injection angle in a direction opposite to the propulsion direction so that the rotary cleaning unit 8 rotates clockwise. Further, one of the first water conveyance path 45 or the second water conveyance path 46 is provided with a jet outlet so that the rotary cleaning means 8 rotates counterclockwise.
以下その動作、作用を説明する。洗浄ポンプ4により噴出された洗浄水は、分水手段5により、第1の導水経路45と連通している吐出経路へ流送される。洗浄導水部11を介して、第1の導水経路45の噴出口47から洗浄水が噴射されると、その噴射反力により回転洗浄手段8は正回転し、被洗浄物13に対して主に片側から洗浄水があたる。 The operation and action will be described below. The washing water ejected by the washing pump 4 is sent by the water diverting means 5 to the discharge path communicating with the first water guide path 45. When cleaning water is jetted from the jet outlet 47 of the first water guide passage 45 via the cleaning water guide section 11, the rotary cleaning means 8 rotates forward due to the jet reaction force, and mainly to the object 13 to be cleaned. Wash water from one side.
次に、分水手段5により、別の吐出経路から、洗浄導水部11を経て、第2の導水経路46の噴出口48から洗浄水が噴射されると、その噴射反力により回転洗浄手段8は反転し、逆回転して、被洗浄物13に対して、主に、正回転の時とは、反対の向きから洗浄水があたる。 Next, when cleaning water is jetted from the discharge port 48 of the second water guide passage 46 from another discharge path through the cleaning water guide section 11 by the water distribution means 5, the rotary cleaning means 8 is driven by the injection reaction force. Is reversed and reversely rotated, and the cleaning water hits the object 13 to be cleaned mainly from the opposite direction to the normal rotation.
また、噴出口47、48の位置や形状は、対称に同一のものを用いなくても様々な方向位置から洗浄水が被洗浄物13にあたるため、洗浄効率を向上することができる。 Moreover, since the cleaning water hits the article 13 to be cleaned from various directions even if the positions and shapes of the ejection ports 47 and 48 are not symmetrically the same, the cleaning efficiency can be improved.
分水手段5が、回転洗浄手段8の導水経路9への洗浄水の供給を切換えることで、回転洗浄手段8の回転方向が切換わる。また、噴射位置はもちろん被洗浄物13に噴射される洗浄水の角度も切換えることが可能となり、被洗浄物13に対して、いろいろな方向から洗浄水を噴射することができる。したがって、食器洗い機本体1の設置性および被洗浄物13のセット性が確保され、洗浄効率も向上する。 The diversion means 5 switches the rotation direction of the rotary cleaning means 8 by switching the supply of cleaning water to the water guide path 9 of the rotary cleaning means 8. In addition to the injection position, the angle of the cleaning water sprayed to the object to be cleaned 13 can be switched, and the cleaning water can be sprayed from various directions to the object to be cleaned 13. Therefore, the installation property of the dishwasher main body 1 and the setting property of the article to be cleaned 13 are ensured, and the cleaning efficiency is improved.
以上のように、本発明にかかる食器洗い機は、洗浄性能が向上するとともに、本体の設置性と被洗浄物がセットできる容量が確保できるので、家庭用の食器洗い機として有用である。 As described above, the dishwasher according to the present invention is useful as a domestic dishwasher because the washing performance is improved and the installation property of the main body and the capacity to set the object to be washed can be secured.
