Description

【0001】
【発明の属する技術分野】
本発明は、洗浄ノズルより食器に向けて洗浄水を噴射して食器を洗浄する食器洗い機に関する。
【0002】
【従来の技術】
従来、この種の食器洗い機は図8に示すように構成していた。以下、その構成について説明する。
【0003】
図に示すように、洗浄槽1は、食器類2を内部に収容するとともに、給水弁3から洗浄水を供給し、底部に溜めている。洗浄ノズル4は、洗浄槽1内に回転自在に支持され、食器類2に向けて洗浄水を噴射する。洗浄ポンプ5は洗浄水を洗浄ノズル4に送り込むものである。また、排水ポンプ6は、洗浄水を機外に排出するものである。
【0004】
水位検知手段7は、洗浄槽1内の水位を検知し、電気信号として出力する。制御装置8は、給水弁3、洗浄ポンプ5、排水ポンプ6などを制御して、洗い・すすぎ・乾燥の各行程を逐次制御するように構成している。洗浄槽1の底部に、循環する洗浄水を溜める排水口部9を設け、ここから洗浄ポンプ5、排水ポンプ6へ洗浄水を循環する。
【0005】
食器洗い機の基本的な動作を以下に簡単に述べると、使用者が食器類2を洗浄槽1内に収容し、洗剤を入れて運転を開始すると、まず、洗浄槽1の底部に水位検知手段7が所定の水位を検知するまで給水弁3から水道水が給水される。そして、洗浄ポンプ5およびヒータ(図示せず)に通電され、洗浄水は加熱されながら洗浄ノズル4から噴出され、食器類2を洗浄する。このとき、洗剤は、界面活性剤による泡立ちを抑えた食器洗い機専用洗剤を使用する。
【0006】
また、所定の洗浄行程を終えた後、排水ポンプ6により汚染物を含んだ洗浄水を機外に排出する。つぎに、新たに水道水が給水され、前述の洗浄行程と同様の動作を数分間行うすすぎ行程を数回繰り返し行う。
【0007】
【発明が解決しようとする課題】
このような従来の食器洗い機では、使用者が誤って、一般の台所用洗剤を使用した場合、洗浄ポンプ5および排水ポンプ6の羽根車によって撹拌され洗浄水に多量の泡が発生し、洗浄水の量が減少する。洗浄ポンプ5および排水ポンプ6は、空気を多量に含むと羽根車が空回りをして機能が低下する。よって、洗浄ポンプ5は洗浄水を洗浄ノズル4に供給できないため、食器類2の洗浄力が低下し、また、排水ポンプ6は機外への排水能力が低下する。
【0008】
また、このとき、洗剤水の大半が泡になっており、水面より上方に存在するため、排水ポンプ6ではその一部しか除去することができなくなり、つぎに使用する際も、一旦入った一般台所用洗剤を除去しておかなければ、残留した洗剤により泡が発生するため使用ができなくなるという問題を有していた。
【0009】
また、泡を除去するためには洗浄槽1に残留する泡を除去するように給水を行い、洗剤水を希釈してから排水をする作業を数回繰り返せばよいが、作業が手間であり、一般使用者には容易に行うことができない。
【0010】
また、泡を検知する手段を設けて洗浄行程の途中で泡を検知した場合、洗浄ポンプ5を停止すると、水位が上昇し、水面の上方に存在する泡が洗浄槽1の開口部や水位検知手段7よりも上に上昇して、場合によっては、機外に流出するという問題を有していた。
【0011】
本発明は上記課題を解決するもので、使用者が誤って一般の台所用洗剤を使用した場合でも、自動的に効率よく洗剤を除去して次回の使用を可能にし、使い勝手を向上することを目的としている。
【0012】
【課題を解決するための手段】
本発明は上記目的を達成するために、洗浄槽内に洗浄ノズルを回転自在に配設し、この洗浄ノズルに洗浄ポンプより洗浄水を供給し、泡検知手段により洗浄槽内の泡立ちを検知するよう構成し、泡検知手段により所定量以上の泡を検知したとき、排水運転を行った後、給水・洗浄ポンプ運転・排水行程のサイクルを複数回繰り返す消泡行程を行うよう構成したものである。
【0013】
これにより、使用者が誤って一般の台所用洗剤を使用した場合でも、自動的に効率よく洗剤を除去することができて、次回の使用を可能にすることができ、使い勝手を向上することができる。
【0015】

【0021】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。なお、従来例と同じ構成のものは同一符号を付して説明を省略する。
【0022】
(実施例1)
図1に示すように、補助タンク10は、洗浄槽1の近傍に設け、排水口部9と補助配管11により連通している。入力手段12は、入力操作を行うもので、洗浄槽1の前方に配設し、制御装置13により給水弁3、洗浄ポンプ5、排水ポンプ6などを制御して、洗い・すすぎ・乾燥の各行程を逐次制御する。
【0023】
補助タンク10の上部に、図2に示すように、水位センサ14と泡検知手段15を設けており、水位センサ14は、フロート16により補助タンク10(洗浄槽1)の水位を検知し、電気信号として出力する。また、泡検知手段15は電極17からなり、補助タンク10内に泡が充満した場合に導通し、電気信号として出力する。
【0024】
また、運転は制御装置13によって水位センサ14等からの電気信号をもとに、給水弁3、洗浄ポンプ5、排水ポンプ6などを制御して、洗い・すすぎ・乾燥の各行程を逐次制御する構成としている。
【0025】
また、泡検知手段15により所定量の泡、すなわち、洗浄ポンプ5が泡を吸い込みポンプ能力が低下する程度の量の泡を検知した場合、排水ポンプ6を運転し、排水行程を行った後、給水・洗浄ポンプ運転・排水行程のサイクル運転を複数回繰り返す消泡行程を運転するよう構成している。また、複数の消泡行程は、最初のサイクルより後の方が洗浄ポンプ5の運転時間と排水ポンプ6の運転時間を長くしている。
【0026】
また、図3に示すように、入力手段12には、消泡コーススイッチ18を設け、前述の消泡行程を運転できるよう構成している。
【0027】
上記構成において図4を参照しながら動作を説明する。使用者が誤って一般の台所洗剤等の食器洗い機用専用洗剤以外の洗剤を使用した場合、洗い行程において、洗浄水が洗浄ポンプ5で撹拌されることにより泡が多量に発生する。泡の量が増加するとともに、洗浄水の水位が下がり、補助配管11を通って補助タンク10に泡が充満し、泡検知手段17により泡を検知すると、図4に示すような消泡行程を行う。このときの泡の量は、所定量、すなわち、洗浄ポンプ5が泡を吸い込みポンプ能力が低下する程度の量に設定している。
【0028】
図4のステップ19にて泡検知をすると、ステップ20にて排水ポンプ6を駆動して排水行程を行う。その後、ステップ21にて給水弁3を駆動し、所定水位まで給水し、ステップ22にて洗浄ポンプ5を3秒間駆動し、ステップ23にて排水ポンプ6を30秒駆動・5秒停止・30秒駆動の排水行程を行い、ステップ24にてこれを4回繰り返す。
【0029】
これにより、効率よく洗剤を除去することができ、次回の使用を可能にすることができ、使い勝手を向上することができる。
【0030】
ここで、当初は泡が多く残り、給水をしても瞬間しか洗浄ポンプ5は機能しないが、消泡行程を繰り返すことで、泡の量が減少し次第に機能する運転時間が長くなる。これに合わせて、ステップ25で給水し、ステップ26で洗浄ポンプ5を10秒間駆動し、ステップ27にて排水ポンプ6を30秒駆動・5秒停止・30秒駆動の排水行程を行う。ステップ28にてこれを2回繰り返すと、ステップ29へ進み終了する。
【0031】
このように、後の消泡行程中の洗浄ポンプ5の運転時間を長くしているため、残留する洗剤の濃度が高いときの洗浄ポンプ運転による、より一層の泡の発生を防ぐとともに、洗剤濃度が低下したとき、洗浄ポンプ5の運転時間を長くすることにより、洗浄槽1や食器類2に付着した洗剤を十分洗い流すことができ、自動的に効率よく泡を除去することができる。
【0032】
また、洗剤洗剤の除去が不十分であっても、消泡コーススイッチ18により、消法行程を運転することができるため、容易に十分な洗剤除去が可能となる。
【0033】
なお、消泡コーススイッチ18を設けず、他のスイッチの組み合わせで消泡行程を運転するようにしても同様の効果を得ることができる。
【0034】
(実施例2)
図1に示す制御装置13は、泡検知手段15により所定量以上の泡を検知したとき、排水ポンプ6を運転して排水行程を行った後、給水と排水行程を同時に所定時間行い、その後給水・洗浄ポンプ運転・排水行程のサイクルを有する消泡行程を少なくとも1回行うよう構成している。また、消泡行程終了時に異常報知をするよう構成している。他の構成は実施例1と同じである。
【0035】
上記構成において図5を参照しながら動作を説明する。使用者が誤って一般の台所洗剤等の食器洗い機用専用洗剤以外の洗剤を使用し、洗い行程において泡が多量に発生して、洗浄ポンプ5が泡を吸い込みポンプ能力が低下する程度の量になると、補助タンク10に泡が充満し、泡検知手段15により泡を検知する。
【0036】
ステップ19にて泡検知をすると、ステップ20にて排水ポンプ6を駆動し、排水行程を行う。その後、ステップ30にて給水弁3を駆動すると同時に排水ポンプを30秒間駆動し、ステップ31にて停止する。この補給水により、排水ポンプ6の能力を一時的に回復し、排水ポンプ6への配管に残留する泡および洗剤濃度の高い洗浄水を機外へ排出する。
【0037】
この後、上記実施例1と同様に、ステップ25にて所定水位まで給水し、ステップ26で洗浄ポンプを10秒間駆動し、ステップ27にて排水ポンプを30秒駆動・5秒停止・30秒駆動の排水行程を行い、ステップ28にてこれを2回繰り返す。このとき、残留する泡と洗剤の量が少なくなっているため、洗浄ポンプ5の運転によるさらなる泡の発生はなく、洗浄槽1や食器類2に付着した洗剤を効率よく除去することができる。
【0038】
つぎに、消泡行程終了後のステップ32にて泡による異常報知を行い、ステップ33へ進み終了する。したがって、泡による異常報知を消泡行程終了後に行うため、消泡行程の途中で使用者が誤って運転を停止するのを防止することができる。
【0039】
(実施例3)
図1に示す制御装置13は、泡検知手段15により所定量以上の泡を検知したとき、排水ポンプ6を運転して排水行程を行った後、給水・洗浄ポンプ運転・排水行程のサイクル運転を複数回繰り返す消泡行程を運転するよう構成し、この消泡行程の最後の行程では、他の消泡行程での給水水位より高くなるよう構成している。他の構成は実施例1と同じである。
【0040】
上記構成において図6を参照しながら動作を説明する。使用者が誤って一般の台所洗剤等の食器洗い機用専用洗剤以外の洗剤を使用し、洗い行程において泡が多量に発生して、洗浄ポンプ5が泡を吸い込みポンプ能力が低下する程度の量になると、補助タンク10に泡が充満し、泡検知手段15により泡を検知する。
【0041】
ステップ19にて泡検知をすると、上記実施例1と同様に、ステップ20にて排水ポンプを駆動し、排水行程を行う。その後、ステップ21にて給水弁3を駆動して所定水位まで給水し、ステップ22にて洗浄ポンプを3秒間駆動し、ステップ23にて排水ポンプを30秒駆動・5秒停止・30秒駆動の排水行程を行い、ステップ24にてこれを4回繰り返す。
【0042】
この後、ステップ34にて所定水位まで給水し、ステップ35にてさらに10秒間の給水を行い、ステップ36にて洗浄ポンプ5を3秒間駆動し、ステップ37にて排水ポンプ6を30秒駆動・5秒停止・30秒駆動の排水行程を行い、ステップ38にてこれを2回繰り返す。
【0043】
このように、ステップ34以降の後の消泡行程では、水位センサ14の水位検知後、さらに給水をして水位を高くしているため、前の消泡行程の水位では届かない上方に残留した泡を除去することができる。
【0044】
(実施例4)
図1に示す制御装置13は、泡検知手段15により洗浄行程中に泡検知を行ったとき、洗浄ポンプ5を運転しながら排水行程を行い、その後給水・洗浄ポンプ運転・排水行程のサイクルを複数回繰り返す消泡行程を行うよう構成している。
他の構成は実施例1または3と同じである。
【0045】
上記構成において図7を参照しながら動作を説明する。使用者が誤って一般の台所洗剤等の食器洗い機用専用洗剤以外の洗剤を使用し、洗い行程において泡が多量に発生して、洗浄ポンプ5が泡を吸い込みポンプ能力が低下する程度の量になると、補助タンク10に泡が充満し、泡検知手段15により泡を検知する。
【0046】
ステップ19にて泡検知をすると、上記実施例1と同様に、ステップ20にて排水ポンプを駆動し、排水行程を行う。その後、ステップ37にて洗浄ポンプ5と排水ポンプ6を同時に30秒間駆動し、その後、上記実施例3と同様に、ステップ21〜ステップ24の動作と、ステップ34〜ステップ39の動作を行う。
【0047】
ここで、洗浄ポンプ5と排水ポンプ6を同時に30秒間駆動するため、洗浄水位が上昇することなく排水を行うことができる。よって、洗浄ポンプ5の停止による水位上昇にともなう泡の上昇をなくすることができ、機外への泡の流出を防止することができる。
【0048】

BACKGROUND OF THE INVENTION
The present invention relates to a dishwasher for cleaning dishes by spraying washing water from a washing nozzle toward the dishes.
[0002]
[Prior art]
Conventionally, this type of dishwasher has been configured as shown in FIG. Hereinafter, the configuration will be described.
[0003]
As shown in the figure, the washing tank 1 accommodates the tableware 2 and supplies washing water from the water supply valve 3 and collects it at the bottom. The cleaning nozzle 4 is rotatably supported in the cleaning tank 1 and injects cleaning water toward the dishes 2. The cleaning pump 5 sends cleaning water to the cleaning nozzle 4. Moreover, the drainage pump 6 discharges washing water outside the apparatus.
[0004]
The water level detection means 7 detects the water level in the cleaning tank 1 and outputs it as an electrical signal. The control device 8 is configured to control the water supply valve 3, the cleaning pump 5, the drainage pump 6, and the like to sequentially control the steps of washing, rinsing, and drying. A drain port 9 is provided at the bottom of the cleaning tank 1 to store circulating cleaning water, and the cleaning water is circulated from here to the cleaning pump 5 and drain pump 6.
[0005]
The basic operation of the dishwasher will be briefly described below. When the user puts the dishes 2 in the washing tub 1 and puts the detergent into operation, first, the water level detection means is placed at the bottom of the washing tub 1. Tap water is supplied from the water supply valve 3 until 7 detects a predetermined water level. Then, the cleaning pump 5 and a heater (not shown) are energized, and the cleaning water is ejected from the cleaning nozzle 4 while being heated to clean the dishes 2. At this time, the detergent is a dishwasher-specific detergent that suppresses foaming due to the surfactant.
[0006]
Further, after the predetermined cleaning process is completed, the cleaning water containing contaminants is discharged out of the apparatus by the drain pump 6. Next, the tap water is newly supplied, and the rinsing process in which the same operation as the above-described cleaning process is performed for several minutes is repeated several times.
[0007]
[Problems to be solved by the invention]
In such a conventional dishwasher, when a user mistakenly uses a general kitchen detergent, a large amount of foam is generated in the washing water that is agitated by the impellers of the washing pump 5 and the drainage pump 6, and the washing water. The amount of decreases. When the washing pump 5 and the drainage pump 6 contain a large amount of air, the impeller rotates idly and the function deteriorates. Therefore, since the cleaning pump 5 cannot supply cleaning water to the cleaning nozzle 4, the cleaning power of the tableware 2 is reduced, and the drainage pump 6 has a reduced drainage capacity to the outside of the machine.
[0008]
At this time, since most of the detergent water is foamed and exists above the surface of the water, only a part of the water can be removed by the drainage pump 6, and once it has been used, If the kitchen detergent is not removed, there is a problem that foam cannot be used because of residual foam.
[0009]
Moreover, in order to remove foam, water supply is performed so as to remove foam remaining in the washing tank 1, and the work of draining water after diluting the detergent water may be repeated several times, but the work is troublesome. It cannot be easily performed by general users.
[0010]
In addition, when bubbles are detected in the course of the cleaning process by providing means for detecting bubbles, the water level rises when the cleaning pump 5 is stopped, and bubbles existing above the water surface are detected in the opening of the cleaning tank 1 and the water level. It has risen above the means 7 and, in some cases, has a problem of flowing out of the machine.
[0011]
