Description

本発明は洗浄槽内に収容した食器に洗浄水を噴射して食器を洗浄する食器洗い機に関するものである。   The present invention relates to a dishwasher for cleaning dishes by spraying washing water onto the dishes stored in a washing tank.

従来、一般家庭用の食器洗い機は洗浄槽内に設置した食器かごに並べられた食器などの被洗浄物に洗浄水を噴射して洗浄するものが用いられてきた。このとき、食器かごに並べられた多数の被洗浄物に満遍なく洗浄水が噴射されるように、洗浄水を噴射する噴射部の配置が重要な要素となる。   2. Description of the Related Art Conventionally, dishwashers for general households have been used in which washing water is sprayed onto an object to be cleaned such as dishes arranged in a dish basket installed in a washing tank. At this time, the arrangement of the injection unit for injecting the cleaning water is an important element so that the cleaning water is uniformly injected onto the many objects to be cleaned arranged in the tableware basket.

特に、底面が矩形の洗浄槽を有する食器洗い機等で、洗浄槽内に多数の被洗浄物が収容できるように食器かごを複数段に設けた場合には、各段の被洗浄物に対して洗浄水が均等に噴射される必要があるが、上段に配置された食器かごに収容された被洗浄物には下方から噴射した洗浄水は下段に並べられた被洗浄物が障害となって充分に洗浄水が行き渡らず、上段に収容された被洗浄物に対する洗浄能力が低下することになる。特に、下段に碗類等を並べた場合、その形状により、下方からの噴射のほとんどが遮断され、上段に収容された被洗浄物の洗浄が行えないという問題があった。   In particular, when the dishwasher has a rectangular washing tank, etc., and the dish basket is provided in multiple stages so that a large number of objects can be accommodated in the washing tank, The wash water needs to be sprayed evenly. However, the wash water sprayed from below is sufficiently obstructed by the wash object placed in the lower stage for the wash object stored in the upper table. In this case, the washing water does not reach the surface, and the washing ability for the object to be washed contained in the upper stage is lowered. In particular, when mosses and the like are arranged in the lower stage, there is a problem that most of the jets from below are blocked by the shape, and the object to be cleaned accommodated in the upper stage cannot be cleaned.

これらの問題を解決するために、洗浄槽内の多方向から被洗浄物に洗浄水を噴射できるように複数の噴射部を配置した食器洗い機が知られている。しかし、複数の噴射部から洗浄水を噴射できるようにするためには、洗浄槽に溜める給水量を増加させる必要があり、洗浄水を加熱するための加熱時間が長くなり、運転時間や消費電力が増加し、使用水量が増加するために洗浄ポンプを大型化する必要が生じるためコストアップにつながり、多量の洗浄水を使用することに伴う騒音、振動の増加などの問題が生じる。   In order to solve these problems, there has been known a dishwasher in which a plurality of spraying units are arranged so that cleaning water can be sprayed onto an object to be cleaned from multiple directions in a cleaning tank. However, in order to be able to inject cleaning water from multiple injection units, it is necessary to increase the amount of water supplied to the cleaning tank, which increases the heating time for heating the cleaning water, and increases the operation time and power consumption. This increases the amount of water used, which necessitates an increase in the size of the cleaning pump, leading to an increase in cost and problems such as increased noise and vibration associated with the use of a large amount of cleaning water.

また、むやみに噴射部の数を増やすと、製品が大型化し、一般家庭用の食器洗い機は、例えばキッチンのワークトップと吊り戸棚との間等、設置スペースが限られるため、製品の設置性を損なうという問題も生じる。   In addition, if the number of spraying parts is increased unnecessarily, the product becomes larger, and the installation space for a general household dishwasher is limited, for example, between the work top of a kitchen and a hanging cupboard. There is also the problem of losing.

そこで、複数の噴射部を設けて洗浄能力を向上させても給水量が増加せず、上記のような問題が発生しないように構成された食器洗い機が開発されている（例えば、特許文献１参照）。   Thus, a dishwasher has been developed that is configured so that the amount of water supply does not increase even if a plurality of injection units are provided to improve the cleaning performance, and the above-described problems do not occur (see, for example, Patent Document 1). ).

この種の食器洗い機では、図６に示すように、底面が矩形の洗浄槽１０２を有し、複数の噴射部は、洗浄槽１０２の下方に回転洗浄ノズル１０３、１０４、洗浄槽１０２の側壁に固定洗浄ノズル１０５が配設されている。これらの各噴射部１０３〜１０５には洗浄ポンプ１１１で加圧された洗浄水が分水装置１１５から順次切り替えて送給される。このように洗浄水は各噴射部１０３〜１０５に順次切り替えて送給されるので、給水量を増加させることがなく、洗浄水は多数の被洗浄物１１０に噴射される。
特開２００４−２６７６６１号公報 In this type of dishwasher, as shown in FIG. 6, the bottom surface has a rectangular washing tank 102, and a plurality of spraying units are provided below the washing tank 102 on the rotary washing nozzles 103 and 104 and on the side wall of the washing tank 102. A fixed cleaning nozzle 105 is provided. Washing water pressurized by the washing pump 111 is sequentially switched from the water diversion device 115 and supplied to each of the injection units 103 to 105. As described above, the cleaning water is sequentially switched and supplied to each of the injection units 103 to 105, so that the cleaning water is injected to a large number of objects to be cleaned 110 without increasing the amount of water supply.

The first, second, and third rotary cleaning nozzles 3, 4, and 7 are rotated by a jet flow in which the supplied cleaning water is ejected from the injection port, and the rotating cleaning water is jetted to inject the lower dish basket 8 and the upper stage. The to-be-cleaned object 10 accommodated in the tableware basket 9 is washed. The fixed cleaning nozzle 5 sprays cleaning water mainly from the injection holes arranged horizontally below the upper tableware basket 9 to the right side of the upper tableware basket 9 to accommodate the inner surface of the object to be cleaned 10 stored downward. In addition, the outer surface of the object to be cleaned 10 is cleaned with the cleaning water sprayed in a fan shape in a substantially horizontal direction from the cleaning water injection port 20a opened at the top.

上記のように下段食器かご８上の被洗浄物１０の配置を左側部に碗類等、右側部に皿類等としたとき、上段食器かご９への被洗浄物１０の収容性を考慮すると、碗類等は皿類等に比べ設置高さが比較的低いため、上段食器かご９の左側部は右側部に比べ一段低い位置に設定される。上段食器かご９に収容される被洗浄物１０の洗浄を洗浄槽２背面に設けられた固定ノズルのみを用いて行った場合を考えると、上段食器かご９の左側部は低い位置に設定されているため、洗浄槽２の背面に設けた固定ノズルから被洗浄物の洗浄を行うには充分な噴射角度が得られない。また、下方に並べられた碗類等が障害となって下方からの洗浄水の供給は望めない。さらに、左側部は空間高さが高いので様々な形状の被洗浄物１０が置けるスペースとしており、固定ノズルは一定範囲の決まった角度のみしか洗浄水を噴射することができないため、被洗浄物の様々な形状や設置姿勢に対し、対応できない。   When the arrangement of the objects to be cleaned 10 on the lower tableware basket 8 is set to the left side such as bowls, and the right side is set to dishes and the like, the capacity of the objects to be cleaned 10 in the upper tableware basket 9 is taken into consideration. Since the installation height of bowls and the like is relatively low compared to dishes and the like, the left side of the upper table basket 9 is set to a position one level lower than the right side. Considering the case where the object to be cleaned 10 accommodated in the upper tableware basket 9 is cleaned using only the fixed nozzle provided on the back of the cleaning tank 2, the left side of the upper tableware basket 9 is set at a low position. Therefore, it is not possible to obtain a spray angle sufficient to clean the object to be cleaned from the fixed nozzle provided on the back surface of the cleaning tank 2. In addition, the supply of washing water from below cannot be expected due to obstacles such as moss arranged below. Furthermore, since the left side has a high space height, it is a space where various shapes of objects to be cleaned 10 can be placed, and the fixed nozzle can inject cleaning water only at a fixed angle within a certain range. Cannot handle various shapes and installation postures.

従って、上段食器かご９に収容される被洗浄物１０の洗浄性能を確保するために、上段食器かご９左側部下方に第３の回転ノズル７を設ける必要がある。   Therefore, in order to ensure the cleaning performance of the article to be cleaned 10 accommodated in the upper tableware basket 9, it is necessary to provide the third rotating nozzle 7 below the left side of the upper tableware basket 9.

一方、食器洗い機本体１の設置性を確保するために、食器洗い機本体１の高さを固定とした場合、上段食器かご９右側部については、下方に比較的設置高さの高い皿類等が設置されるため回転ノズルを配設するスペースが取れないが、上段食器かご９の被洗浄物１０が高い位置に収容されるため、洗浄槽２背面に設けた固定ノズル５から充分な噴射角度を得ることができ、また、皿類の形状から下方からの洗浄水の供給を得ることができる。さらに、背の低いコップや湯飲みといった円筒状の食器を設置するスペースとしており、ある程度設置姿勢や食器形状が定まるため、固定ノズル５を用いても洗浄性能を確保することができる。   On the other hand, when the height of the dishwasher main body 1 is fixed in order to secure the installation property of the dishwasher main body 1, there is a relatively high installation dish or the like on the right side of the upper table basket 9. Since it is installed, there is not enough space to arrange the rotating nozzle, but since the object 10 to be cleaned in the upper table basket 9 is stored at a high position, a sufficient injection angle is set from the fixed nozzle 5 provided on the back surface of the cleaning tank 2. In addition, the supply of washing water from below can be obtained from the shape of the dishes. Furthermore, it is a space for installing cylindrical tableware such as a short cup or a cup of water, and since the installation posture and tableware shape are determined to some extent, the cleaning performance can be ensured even if the fixed nozzle 5 is used.

また、第３の回転洗浄ノズル７を追加することによる被洗浄物１０の設置性については、回転洗浄ノズル導水路６を後方から前方へ洗浄槽２中央に向けて延設することにより、前後方向への導水路を持つことにより、被洗浄物１０設置時に邪魔になることがなく、被洗浄物１０の設置性を確保している。   Moreover, about the installation property of the to-be-cleaned object 10 by adding the 3rd rotation washing nozzle 7, it extends in the front-back direction by extending the rotation washing nozzle conduit 6 from the rear toward the front toward the center of the washing tank 2. By having the water conduit to the, the installation property of the object to be cleaned 10 is ensured without interfering with the object 10 to be cleaned.

洗浄槽２内に第１、第２および第３の各回転洗浄ノズル３、４、７および固定洗浄ノズル５から噴射された洗浄水は被洗浄物１０を洗浄して洗浄槽２の下部に流下し、排水口１２に集められて再びヒータ１４によって加熱され、残菜フィルタ１３を透過して再び洗浄ポンプ１１から分水手段１５を経て第１、第２および第３の各回転洗浄ノズル３、４、７、固定洗浄ノズル５に送給される。洗浄水が噴射されて被洗浄物１０から脱落した残菜は残菜フィルタ１３に捕集される。また洗浄水の温度は温度センサ１７によって検出されており、所定温度を超えるとヒータ１４への通電が停止されるので、洗浄に適した温度が維持される。   The cleaning water sprayed from the first, second and third rotary cleaning nozzles 3, 4, 7 and the fixed cleaning nozzle 5 in the cleaning tank 2 cleans the object to be cleaned 10 and flows down to the lower part of the cleaning tank 2. The first, second and third rotary cleaning nozzles 3 are collected at the drainage port 12 and heated again by the heater 14, pass through the leftover filter 13, and again from the cleaning pump 11 through the water distribution means 15. 4 and 7 are fed to the fixed cleaning nozzle 5. The leftovers dropped from the object to be cleaned 10 after the washing water is jetted are collected in the leftover filter 13. Further, the temperature of the cleaning water is detected by the temperature sensor 17, and when the temperature exceeds a predetermined temperature, the energization to the heater 14 is stopped, so that a temperature suitable for cleaning is maintained.

所定時間の洗浄工程が終了すると、汚れを含む洗浄水は排水ポンプ１８から機外に排出され、洗浄槽２内に新たに洗浄水が給水される。給水された洗浄水は洗浄ポンプ１１の運転により第１、第２および第３の各回転洗浄ノズル３、４、７および固定洗浄ノズル５から噴射され、被洗浄物１０に付着した洗剤や残菜等洗い流すすすぎ工程が実行される。このすすぎ工程は、所定時間の運転の後、すすぎによって洗剤や残菜を洗い出した洗浄水は排水ポンプ１８から機外に排出され、洗浄槽２内には新たな洗浄水が給水され、再びすすぎ動作を行う工程を３回実行し、洗浄水を機外に排出してすすぎ工程を終了する。   When the cleaning process for a predetermined time is completed, the cleaning water containing dirt is discharged from the drain pump 18 to the outside of the apparatus, and the cleaning water is newly supplied into the cleaning tank 2. The supplied cleaning water is sprayed from the first, second and third rotary cleaning nozzles 3, 4, 7 and the fixed cleaning nozzle 5 by the operation of the cleaning pump 11, and the detergent and leftovers attached to the object to be cleaned 10. A rinsing step for flushing is performed. In this rinsing process, after a predetermined time of operation, the washing water from which the detergent and the remaining vegetables have been washed out by rinsing is discharged from the drainage pump 18 to the outside of the machine, and new washing water is supplied into the washing tank 2 and rinsed again. The process of performing the operation is executed three times, and the rinsing process is completed by discharging the wash water out of the machine.

続いて乾燥工程が実行され、図示しない送風機から洗浄槽２内に送給される外気がヒータ１４によって加熱され、送風と加温との両方の効果によって被洗浄物１０に付着した水滴の蒸発が促進される。この乾燥工程が所定時間実施された後、運転が停止されて食器洗浄のすべての工程が終了する。   Subsequently, a drying process is executed, and the outside air fed into the cleaning tank 2 from a blower (not shown) is heated by the heater 14, and evaporation of water droplets adhering to the object to be cleaned 10 by both effects of blowing and heating is performed. Promoted. After this drying process is carried out for a predetermined time, the operation is stopped and all the steps of washing the dishes are completed.

上記各工程における洗浄槽２内への洗浄水の給水制御、洗浄ポンプ１１および排水ポンプ１８の駆動制御、温度センサ１７による温度検出に基づくヒータ１４への通電制御、乾燥工程における送風機の駆動制御などは、食器洗い機本体１内に設けられた図示しない制御装置によって実施される。   Feeding control of washing water into the washing tank 2 in each of the above processes, driving control of the washing pump 11 and the drainage pump 18, energization control to the heater 14 based on temperature detection by the temperature sensor 17, driving control of the blower in the drying process, etc. Is implemented by a control device (not shown) provided in the dishwasher body 1.

図３は、洗浄槽２内から下段食器かご８および上段食器かご９を外部に取り出した状態を正面側から見た状態を示すもので、固定洗浄ノズル５および第３の回転洗浄ノズル７の形態をわかりやすく示している。洗浄槽２背面に配設する導水路ユニット２１は扁平筒状に形成され、固定洗浄ノズル５のための垂直部位５ａ、水平部位右側５ｂおよび第３の回転洗浄ノズル７のための水平部位左側６ａによって略十字状に形成される。また、図中破線の位置において仕切りが設けられ、経路が２つに分けられている。導水路ユニット２１の下端は左側の経路、右側の経路がそれぞれ別々に分水手段１５に接続されている。ここで、左側経路については、噴射口がなく、第３の回転洗浄ノズル７の導水路として構成する。水平部位右側５ｂおよび水平部位左側６ａは、上段食器かご９が左右で高さが異なる段差を設けた形状に形成されていることに対応して、左右で高さ位置が異なる。   FIG. 3 shows a state in which the lower table basket 8 and the upper table basket 9 are taken out from the inside of the cleaning tank 2 as viewed from the front side. The forms of the fixed cleaning nozzle 5 and the third rotary cleaning nozzle 7 Is clearly shown. The water conduit unit 21 disposed on the back surface of the cleaning tank 2 is formed in a flat cylindrical shape, and a vertical portion 5 a for the fixed cleaning nozzle 5, a right side portion 5 b for the fixed cleaning nozzle 5, and a horizontal portion left side 6 a for the third rotary cleaning nozzle 7. Is formed in a substantially cross shape. In addition, a partition is provided at a position indicated by a broken line in the drawing, and the route is divided into two. At the lower end of the water conduit unit 21, the left route and the right route are separately connected to the water distribution means 15. Here, the left-side path is configured as a water conduit for the third rotary cleaning nozzle 7 without an injection port. The horizontal part right side 5b and the horizontal part left side 6a have different height positions on the left and right, corresponding to the fact that the upper table basket 9 is formed in a shape having steps with different heights on the left and right.

また、水平部位左側６ａには前方へ延設した回転洗浄ノズル導水路６ｂが接続され、さらに、その回転洗浄ノズル導水路６ｂの先端部であって、上段食器かご９左側部下方中央付近に第３の回転洗浄ノズル７が配設される。また、回転洗浄ノズル導水路６ｂは水平部位左側６ａと着脱可能に接続されており、下段食器かご８左側に高さの高い食器などを収容する場合には回転洗浄ノズル導水路６ｂおよび第３の回転洗浄ノズル７を取り外すことにより、下段食器かご８への大きい被洗浄物１０の設置性を高めることができる。図４に導水路ユニット２１の水平部位左側６ａと回転洗浄ノズル導水路６ｂとの接続構成を詳し
く示している。回転ノズル導水路６ｂは略中空円筒状をなしており、その一端部外周には、９０度毎に爪部６０ｂが４ヶ所設けられ、一方、導水路ユニット２１の水平部位左側６ａの接続部には爪部６０ｂに対応した溝部６０ａが４ヶ所配設される。爪部６０ｂと溝部６０ａとを前方から穴位置を合わせて挿入したのち、右方向に約１５度回転させ、突起６０ｄが突起６０ｃを乗り越えることにより係止させ、回転洗浄ノズル導水路６と固定洗浄ノズル５を水密に接続する。 Further, a rotary washing nozzle conduit 6b extending forward is connected to the left side 6a of the horizontal portion, and further, at the tip of the rotary washing nozzle conduit 6b, near the lower center of the left side of the upper tableware basket 9. 3 rotary cleaning nozzles 7 are arranged. Further, the rotary cleaning nozzle conduit 6b is detachably connected to the horizontal portion left side 6a, and in the case of storing high tableware or the like on the left side of the lower table basket 8, the rotary cleaning nozzle conduit 6b and the third By removing the rotary cleaning nozzle 7, it is possible to improve the installation property of the large object 10 to be cleaned in the lower table basket 8. FIG. 4 shows in detail the connection configuration between the horizontal portion left side 6a of the water conduit unit 21 and the rotary cleaning nozzle water conduit 6b. The rotating nozzle water conduit 6b has a substantially hollow cylindrical shape, and four claw portions 60b are provided on the outer periphery of one end portion every 90 degrees, while the connection portion of the horizontal portion left side 6a of the water conduit unit 21 is provided. Four groove portions 60a corresponding to the claw portions 60b are disposed. After inserting the claw portion 60b and the groove portion 60a with the hole positions aligned from the front, the claw portion 60b and the groove portion 60a are rotated to the right by about 15 degrees and locked by the protrusion 60d getting over the protrusion 60c, and fixed to the rotary cleaning nozzle conduit 6 and fixed cleaning. The nozzle 5 is connected in a watertight manner.

固定ノズル５の水平部位右側５ｂには、上段食器かご９に収容された被洗浄物１０に洗浄水を噴射する洗浄水噴射口２０ｂが複数に開口し、上段食器かご９に収容された被洗浄物１０の内面に向けて上方に洗浄水を噴射する。また、垂直部位５ａの上方には洗浄水噴射口２０ａが開口し、略水平方向の扇状に洗浄水を噴射する。尚、水平部位５ｂに設けられた複数の洗浄水噴射口２０ｂそれぞれは、必ずしも上向きに洗浄水を噴射するのではなく、例えば、箸やスプーン等の収容場所に近い洗浄水噴出口は横向きに洗浄水を噴射して汚れを落とし難い箸やスプーンなどに重点的に洗浄水を噴射するようにしてもよい。また、導水路ユニット２１の水平部位右側５ｂと水平部位左側６ａは、上段食器かご９が段差のないものである場合には、左右で高さ位置が異なる形状に形成する必要はない。   On the right side 5b of the horizontal portion of the fixed nozzle 5, a plurality of cleaning water injection ports 20b for injecting cleaning water to the object to be cleaned 10 accommodated in the upper tableware basket 9 are opened, and the object to be cleaned accommodated in the upper tableware basket 9 is opened. Washing water is jetted upward toward the inner surface of the object 10. Further, a cleaning water injection port 20a is opened above the vertical portion 5a, and the cleaning water is injected in a fan shape in a substantially horizontal direction. In addition, each of the plurality of cleaning water injection ports 20b provided in the horizontal portion 5b does not necessarily inject the cleaning water upward. For example, the cleaning water outlet near the accommodation place such as chopsticks and a spoon is cleaned sideways. The cleaning water may be sprayed mainly on chopsticks or spoons that are difficult to remove by spraying water. Further, the horizontal part right side 5b and the horizontal part left side 6a of the water conduit unit 21 do not need to be formed in shapes having different height positions on the left and right when the upper table basket 9 has no step.

第３の回転洗浄ノズル７の上面には上段食器かご９左側部に収容された被洗浄物に下方から洗浄水を噴射する洗浄水噴射口が複数に開口し、上段食器かご９左側部に収容された被洗浄物１０に真下から洗浄水を噴射することができ、様々な食器の形状や設置姿勢に対しても、ムラなく洗浄することができる。   The upper surface of the third rotary cleaning nozzle 7 has a plurality of cleaning water injection ports for injecting cleaning water from below into the object stored in the left side of the upper table basket 9 and accommodated in the left side of the upper table basket 9 Cleaning water can be sprayed onto the object to be cleaned 10 from directly below, and even various tableware shapes and installation postures can be cleaned evenly.

固定ノズル５は扁平な筒状に形成することによって、洗浄槽２の背面から突出して被洗浄物の収容スペースを削減してしまうことがない。また、垂直部位５ａ上部に設けられた洗浄水噴射口２０ａは、略水平方向の扇状に洗浄水を噴射するので、洗浄槽２内に収容された被洗浄物の上方から洗浄水を当てることができ、洗浄水噴射の主体となっている下方から噴射される洗浄水で洗浄され難い被洗浄物１０の上面部分を洗浄することができる。特に糸底のある被洗浄物１０、例えば、図１に示す湯飲み１０ａのように糸底のある食器は、糸底内に細かい残菜が残りやすくなるが、これに上方から洗浄水が噴射されることにより、細かい残菜が洗い出され、全ての面に洗浄水が行き渡る効果が得られる。また、回転ノズル導水路６は円筒形状とすることで、上面への水滴の付着をなくし、乾燥性能を向上させている。   By forming the fixed nozzle 5 in a flat cylindrical shape, the fixed nozzle 5 does not protrude from the back surface of the cleaning tank 2 and does not reduce the storage space for the object to be cleaned. Moreover, since the washing water injection port 20a provided in the upper part of the vertical part 5a injects the washing water in a substantially horizontal fan shape, the washing water can be applied from above the article to be washed contained in the washing tank 2. It is possible to clean the upper surface portion of the object to be cleaned 10 which is difficult to be cleaned with the cleaning water sprayed from below, which is the main body of the cleaning water injection. In particular, an object to be cleaned 10 having a thread bottom, for example, a tableware having a thread bottom such as a cup 10a shown in FIG. 1, is likely to leave fine leftovers in the thread bottom. Fine leftovers are washed out, and the effect of spreading wash water on all surfaces is obtained. Moreover, the rotating nozzle water conduit 6 is made into a cylindrical shape, thereby eliminating the adhesion of water droplets to the upper surface and improving the drying performance.

複数の噴射部に選択的に洗浄水を送給する分水手段１５は本実施形態の構成のように４ヶ所の噴射部に選択的に洗浄水を送給する場合には、図５に示すような簡単な構造に分水手段１５を構成することができる。   In the case of selectively supplying cleaning water to four injection units as in the configuration of the present embodiment, the water distribution means 15 that selectively supplies cleaning water to a plurality of injection units is shown in FIG. The water dividing means 15 can be configured in such a simple structure.

図５は、分水手段１５の構成例を模式的に示すもので、中心部に洗浄ポンプ１１から洗浄水が供給される円筒状の分水弁４０の周面上には１ヵ所の送水開口部４１が開口し、紙面上方を０度として時計回りの４５度方向に固定洗浄ノズルに配管された送水配管４２、１３５度方向に第２の回転洗浄ノズル４に配管された送水配管４３、２２５度方向に第１の回転洗浄ノズル３に配管された送水配管４４、３１５度方向に第３の回転洗浄ノズル７に配管された送水配管４５がそれぞれ分水弁４０の周面に対向して配置されている。   FIG. 5 schematically shows an example of the configuration of the water distribution means 15. One water supply opening is provided on the peripheral surface of a cylindrical water distribution valve 40 to which the cleaning water is supplied from the cleaning pump 11 at the center. Portion 41 opens, water supply pipe 42 piped to the fixed cleaning nozzle in the clockwise 45 degree direction with 0 degree above the paper surface, water supply pipes 43 and 225 piped to the second rotary cleaning nozzle 4 in the 135 degree direction The water supply pipe 44 piped to the first rotary cleaning nozzle 3 in the direction of the angle and the water supply pipe 45 piped to the third rotary cleaning nozzle 7 in the direction of the 315 degree are arranged to face the peripheral surface of the water diversion valve 40, respectively. Has been.

分水弁４０を図示しない駆動手段により回転角度９０度毎に回動させ、図５（ａ）に示す角度位置に回動させると、送水開口部４１が送水配管４４の方向に開口するので、洗浄ポンプ１１から分水弁４０内に供給された洗浄水は第１の回転洗浄ノズル３に送給される。また、図５（ｂ）に示す角度位置に回動させると、送水開口部４１が送水配管４３の方向に開口するので、洗浄ポンプ１１から分水弁４０内に供給された洗浄水は第２の回転洗浄ノズル４に送給される。また、図５（ｃ）に示す角度位置に回動させると、送水開口部
４１が送水配管４２方向に開口するので、固定洗浄ノズル５に洗浄水が送給される。また、図５（ｄ）に示す角度位置に分水弁４０を回動させると、送水開口部４１が送水配管４５の方向に開口するので、第３の回転洗浄ノズル７に洗浄水が送給される。 When the water diversion valve 40 is rotated every 90 degrees by a driving means (not shown) and rotated to the angular position shown in FIG. 5A, the water supply opening 41 opens in the direction of the water supply pipe 44. The cleaning water supplied from the cleaning pump 11 into the diversion valve 40 is supplied to the first rotary cleaning nozzle 3. 5B, the water supply opening 41 opens in the direction of the water supply pipe 43, so that the cleaning water supplied from the cleaning pump 11 into the diversion valve 40 is the second. To the rotary cleaning nozzle 4. 5C, the water supply opening 41 opens in the direction of the water supply pipe 42, so that the cleaning water is supplied to the fixed cleaning nozzle 5. When the water diversion valve 40 is rotated to the angular position shown in FIG. 5 (d), the water supply opening 41 opens in the direction of the water supply pipe 45, so that cleaning water is supplied to the third rotary cleaning nozzle 7. Is done.

分水手段１５を上記構成例のように構成することにより、前述した第１の回転洗浄ノズル３にのみ洗浄水が送給される状態、第２の回転洗浄ノズル４にのみ洗浄水が送給される状態、固定洗浄ノズル５にのみ洗浄水が送給される状態、第３の回転洗浄ノズルにのみ洗浄水が送給される状態、に順次切り替えることができる。   By configuring the water dividing means 15 as in the above configuration example, the cleaning water is supplied only to the first rotary cleaning nozzle 3 described above, and the cleaning water is supplied only to the second rotary cleaning nozzle 4. It is possible to sequentially switch to a state where cleaning water is supplied only to the fixed cleaning nozzle 5 and a state where cleaning water is supplied only to the third rotary cleaning nozzle.

このように複数の噴射部に選択的に洗浄水を送給するようにすることにより、複数の噴射部の全てに同時に洗浄水を送給した場合に洗浄槽２内に溜める給水量が多くなり、使用水量の増加および温度上昇時間の増加に伴う消費電力量の増加、大型化などの問題を解消することができる。   By supplying the cleaning water selectively to the plurality of jetting units in this way, the amount of water supplied in the cleaning tank 2 is increased when the cleaning water is supplied to all of the plurality of jetting units at the same time. Problems such as an increase in power consumption and an increase in size due to an increase in the amount of water used and an increase in temperature rise time can be solved.

以上のように、本発明にかかる食器洗い機は回転洗浄ノズルと固定洗浄ノズルを効果的に組み合わせることにより、高い洗浄性能と被洗浄物収容性を得ることが可能となるので、洗浄水を噴射して被洗浄物の洗浄を行う食器洗い機等として有用である。   As described above, the dishwasher according to the present invention can obtain high cleaning performance and washability by effectively combining the rotary cleaning nozzle and the fixed cleaning nozzle. Therefore, it is useful as a dishwasher for cleaning an object to be cleaned.
