Description

本発明は、食器等の被洗浄物に洗浄水を噴射して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 by spraying cleaning water onto an object to be cleaned such as tableware.
図4に示すように、食器洗い機は、基本的に食器洗い機本体20と、その筺体5から外部に引き出された給水ホース3及び排水ホース13とにより構成され、食器洗い機を所定場所に設置する際に、給水ホース3を水道管路などの給水配管18に、排水ホース13を排水配管19に接続することにより使用可能な状態となる。食器洗い機本体20は給水ホース3から給水される水又は湯を用いて食器等の被洗浄物9を洗浄し、洗浄により生じた汚濁水は排水ホース13から排水配管19に排出することができる。   As shown in FIG. 4, the dishwasher basically includes a dishwasher main body 20, a water supply hose 3 and a drainage hose 13 drawn out from the housing 5, and the dishwasher is installed at a predetermined place. In addition, the water supply hose 3 can be used by connecting the water supply hose 3 to the water supply pipe 18 such as a water pipe and the drainage hose 13 to the drainage pipe 19. The dishwasher main body 20 can wash the object 9 such as tableware using water or hot water supplied from the water supply hose 3, and polluted water generated by the washing can be discharged from the drain hose 13 to the drain pipe 19.
給水ホース3を通じて供給される水は、給水弁4により所要量が所要のタイミングで食器洗い機本体20内に設けられた洗浄槽2に給水されるように開閉制御され、給水により洗浄槽2の底部に貯留された水には洗剤が混合されると共にヒータ8により洗浄に適した温度に加熱され、洗浄水として被洗浄物9を洗浄する用に供される。この洗浄水は図示しない洗浄ポンプにより吸い上げられ、回転する洗浄ノズル7から被洗浄物9に噴射され、被洗浄物9を洗浄した洗浄水が再び洗浄槽2に戻る洗浄水循環により被洗浄物9の洗浄が実施される。   The water supplied through the water supply hose 3 is controlled to be opened and closed by the water supply valve 4 so that the required amount is supplied to the washing tub 2 provided in the dishwasher main body 20 at the required timing. The stored water is mixed with a detergent and heated by a heater 8 to a temperature suitable for cleaning, and used as cleaning water for cleaning the article 9 to be cleaned. This cleaning water is sucked up by a cleaning pump (not shown), sprayed to the object to be cleaned 9 from the rotating cleaning nozzle 7, and the cleaning water that has cleaned the object to be cleaned 9 returns to the cleaning tank 2 again by circulating the cleaning water. Washing is performed.
被洗浄物9は洗浄ノズル7からの洗浄水が効果的に噴射されるように洗浄槽2内に配置できるように構成された食器カゴ10上に載置され、洗浄槽2の前面を開閉する扉11を開くことにより、食器カゴ10を前面外部に引き出すことができ、被洗浄物9の出し入れを容易に行うことができる。   The object to be cleaned 9 is placed on the tableware basket 10 configured to be arranged in the cleaning tank 2 so that the cleaning water from the cleaning nozzle 7 is effectively jetted, and opens and closes the front surface of the cleaning tank 2. By opening the door 11, the tableware basket 10 can be pulled out to the outside of the front surface, and the article 9 to be cleaned can be easily put in and out.
筺体5から引き出される給水ホース3が洗浄槽2内に開口する吐出口は、製品の溢水面に対して一定以上の高さが必要であるため、図示するように筺体5からの引き出し口は筺体5の上方に設定され、その内側に給水弁4が配置されている。また、排水ホース13についても、洗浄槽2内に貯留した洗浄水が外部に抜け出すことがないように貯留水面より上方に管路が位置するように立ち上げる必要があるため、図示するように筺体5からの引き出し部分は筺体5の上方に設定されている。筺体5から引き出された給水ホース3の先端は給水配管18の端部に設けられた止水栓17に接続部材16を用いて接続され、排水ホース13の先端は排水配管19に接続される。(特許文献1参照)。   Since the discharge port through which the water supply hose 3 drawn out from the housing 5 opens into the cleaning tank 2 needs to have a certain height or more with respect to the overflow surface of the product, the outlet from the housing 5 is the housing as shown in the figure. 5 is set above, and the water supply valve 4 is arranged inside thereof. Further, the drainage hose 13 also needs to be raised so that the washing water stored in the cleaning tank 2 does not escape to the outside so that the pipe line is positioned above the stored water surface. The lead-out portion from 5 is set above the housing 5. The front end of the water supply hose 3 drawn out from the housing 5 is connected to a water stop cock 17 provided at the end of the water supply pipe 18 using a connection member 16, and the front end of the drain hose 13 is connected to a drain pipe 19. (See Patent Document 1).
上記のような給排水管路の構成において、給排水管路の接続状態の不具合やホースの損傷などがあると、漏水が発生する恐れがある。漏水は錆の発生や食器洗い機を設置した床面に損傷を与えるなどの被害を与えかねないので、漏水を防止すると共に漏水が生じたときには、それを検出する手段を設けることが要求される。   In the configuration of the water supply / drainage pipe as described above, if there is a malfunction in the connection state of the water supply / drainage pipe or damage to the hose, water leakage may occur. Leakage may cause damage such as generation of rust and damage to the floor surface on which the dishwasher is installed. Therefore, it is required to provide means for preventing water leakage and detecting the occurrence of water leakage.
給水管路からの漏水を検知するための手段を設けた食器洗い機が知られており(特許文献2参照)、筐体の背面に配設した給水弁に給水ホースが接続され、給水弁と給水ホースとの接続部位に下方に水溜ケースを設け、接続部位から生じた漏水を水溜ケースに貯留して、その貯留水位が異常水位に達した場合に、異常水位検知手段によって検知できるように構成されている。

Japanese Patent Laid-Open No. 2003-210378 Japanese Patent Laid-Open No. 09-038013
食器洗い機は、その設置に際して給水及び排水のための管路接続工事が伴い、設置工事は工事業者の手に委ねられるので、食器洗い機が正常に機能していても設置工事に不備があると設置された食器洗い機に不具合が生じることになる。特に、給排水の管路接続に不備があると漏水という建物に被害を与えかねない問題が発生する。従って、管路接続の不備があっても、それに伴う被害の発生を最小限に抑える対策を講じておくことが要求される。   Dishwashers are installed with pipe connection work for water supply and drainage at the time of installation, and the installation work is left to the contractor's hands, so if the dishwasher is functioning properly, it will be installed if the installation work is incomplete The dishwasher will be defective. In particular, inadequate water supply and drainage pipe connections will cause problems such as water leakage that can damage buildings. Therefore, it is required to take measures to minimize the occurrence of damage caused by inadequate pipe connection.
給水管路から漏水する恐れは、前述したように給水ホースの接続部位だけでなく、ホースそのものが設置工事中に損傷を受けていたことに起因する場合もあり、給水配管と給水ホースとの接続部位から食器洗い機内の洗浄槽に至る給水管路で漏水が発生し得ることを想定しておく必要がある。   The possibility of water leakage from the water supply pipe line may be due to the fact that the hose itself was damaged during the installation work as well as the connection part of the water supply hose as described above. It is necessary to assume that water leakage may occur in the water supply line from the site to the washing tank in the dishwasher.
また、給水弁は食器洗い機本体に設けられているため、給水配管から給水弁に至る給水管路には、食器洗い機を使用していない場合でも給水配管からの水圧が加わっている状態にあり、僅かな漏水であってもそれが常時続くことになり、設置床面など建物に与える影響は大きなものとなる。しかも、漏水発生の可能性がある部位は食器洗い機の背面側であり、使用者が漏水に気付き難い状況にある。   In addition, since the water supply valve is provided in the dishwasher body, the water pressure from the water supply pipe is applied to the water supply line from the water supply pipe to the water supply valve even when the dishwasher is not used. Even a small amount of water leakage will always continue, and the impact on the building, such as the installation floor, will be significant. In addition, the portion where water leakage may occur is the back side of the dishwasher, and it is difficult for the user to notice the water leakage.
然るに、上記従来技術の水溜ケースを設ける構成では、給水ホースと給水弁との接続部位からの漏水のみにしか対応できず、しかも相当量の漏水があるまで検知できない課題があった。   However, in the configuration in which the above-described conventional water reservoir case is provided, there is a problem that only water leakage from the connection portion between the water supply hose and the water supply valve can be dealt with and cannot be detected until a considerable amount of water leaks.
本発明が目的とするところは、給水管路からの漏水による影響を抑制すると共に漏水を検知する手段を設けた食器洗い機を提供することにある。   An object of the present invention is to provide a dishwasher provided with means for detecting leakage while suppressing the influence of leakage from a water supply pipeline.
上記目的を達成するための本発明に係る食器洗い機は、食器洗い機本体の筺体内から引き出されて給水配管に接続する給水ホースの前記給水配管との接続位置の近傍に給水弁が設けられてなることを特徴とする。   In order to achieve the above object, a dishwasher according to the present invention is provided with a water supply valve in the vicinity of a connection position of a water supply hose that is drawn out of the housing of the dishwasher body and connected to the water supply pipe. It is characterized by that.
上記構成によれば、給水弁が給水ホースの給水配管側に配設されているので、給水弁が閉じられている間、即ち、食器洗い機本体に給水していない状態や食器洗い機が使用されていない状態では、給水弁より下流側には水流や水圧が加わることはなく、仮に給水ホースやその接続部位に漏水の可能性があっても洗浄槽に給水している間だけの漏水に抑えられ、漏水に伴う被害は最小限に抑えられる。   According to the above configuration, since the water supply valve is disposed on the water supply pipe side of the water supply hose, the state where the water supply valve is closed, that is, the state where water is not supplied to the dishwasher body or the dishwasher is used. If there is no water flow or water pressure on the downstream side of the water supply valve, there is no possibility of water leakage at the water supply hose or its connected part. Damage caused by leakage is minimized.
上記構成において、給水弁及び給水配管の端部に設けられた止水栓の少なくともいずれか一方の近傍に漏水検知手段を設けることが好適で、給水弁あるいは止水栓やその接続部位から漏水が発生すると、漏水検知手段により速やかに漏水が検知されるので、漏水に対する対応を速やかに実行することができる。   In the above configuration, it is preferable to provide a water leakage detection means in the vicinity of at least one of the water stop valves provided at the ends of the water supply valve and the water supply pipe, and water leaks from the water supply valve or the water stop cock or its connection part. When it occurs, the water leakage detection means detects the water leakage quickly, so that it is possible to quickly cope with the water leakage.
本発明によれば、設置に際して給水及び排水のための管路接続工事が伴う食器洗い機の設置工事に不備があった場合においても、給水弁を給水配管との接続部位に配置しているので、漏水の発生を最小限に抑えることができる。また、漏水検知手段の配置によって漏水の発生を速やかに検知することができる。   According to the present invention, even when there is a deficiency in the installation work of the dishwasher accompanied by pipe connection work for water supply and drainage at the time of installation, the water supply valve is arranged at the connection part with the water supply pipe, The occurrence of water leakage can be minimized. Moreover, the occurrence of water leakage can be quickly detected by the arrangement of the water leakage detection means.
図1は、実施形態に係る食器洗い機の構成を示すもので、キッチンカウンタ下などに設置するビルトインタイプの食器洗い機として構成されたものである。尚、図中に示す符号は、従来技術の構成と共通する構成要素には同一の符号を付している。   FIG. 1 shows a configuration of a dishwasher according to an embodiment, which is configured as a built-in type dishwasher installed under a kitchen counter or the like. In addition, the code | symbol shown in a figure attaches | subjects the same code | symbol to the component which is common in the structure of a prior art.
図1において、食器洗い機本体1は筺体5内に洗浄槽2が配設され、その前面は扉11によって開閉自在に構成されている。扉11を開くと、洗浄槽2内に配設された食器カゴ10を前方に引き出すことができ、食器カゴ10に食器等の被洗浄物9を載せ、食器カゴ10を洗浄槽2内に押し入れて扉11を閉じると被洗浄物9を洗浄できる状態とすることができる。   In FIG. 1, a dishwasher main body 1 is provided with a washing tub 2 in a housing 5, and the front surface of the dishwasher body 1 is configured to be freely opened and closed by a door 11. When the door 11 is opened, the tableware basket 10 disposed in the washing tub 2 can be pulled out forward, an object to be cleaned 9 such as tableware is placed on the tableware basket 10, and the tableware basket 10 is pushed into the washing tub 2. When the door 11 is closed, the object 9 can be cleaned.
前記筺体5の背面から給水ホース3及び排水ホース13が引き出され、給水ホース3は水道管路等の給水配管18に接続され、排水ホース13は排水配管19に接続される。給水ホース3は一端が洗浄槽2内に開口し、他端が給水弁4を介して給水配管18に接続される。前記給水弁4は、図示しない電気配線によって食器洗い機本体1に電気的接続がなされ、食器洗い機本体1に設けられた制御手段により開閉操作がなされる。   A water supply hose 3 and a drainage hose 13 are drawn out from the rear surface of the housing 5, the water supply hose 3 is connected to a water supply pipe 18 such as a water pipe, and the drainage hose 13 is connected to a drainage pipe 19. One end of the water supply hose 3 opens into the cleaning tank 2, and the other end is connected to the water supply pipe 18 via the water supply valve 4. The water supply valve 4 is electrically connected to the dishwasher main body 1 by electric wiring (not shown), and is opened and closed by control means provided in the dishwasher main body 1.
食器洗い機の設置は指定工事業者によって施工され、筺体5の背面から引き出されている給水ホース3及び排水ホース13の管路接続及び電源コードや接地線の電気的接続を設置場所の壁面や床面に配した配管路やコンセントに接続した後、キッチンカウンタ下などの所定の設置場所に食器洗い機本体1を固定することにより設置完了する。   The dishwasher is installed by a designated contractor, and the pipe connection of the water supply hose 3 and the drainage hose 13 drawn out from the back of the housing 5 and the electrical connection of the power cord and grounding wire are installed on the wall and floor of the installation site. After connecting to the pipe line or outlet arranged in the wall, the installation is completed by fixing the dishwasher body 1 to a predetermined installation place such as under the kitchen counter.
設置された食器洗い機の前面に設けられた操作パネルから運転開始操作すると、給水弁4が開かれて給水配管18から供給される水又は湯が止水栓17、給水弁4、給水ホース3を通じて洗浄槽2内に給水される。給水された水や湯が洗浄槽2の底部に所定量に貯留されると給水弁4は閉じられ、貯留された水はヒータ8によって適温に加熱されると同時に洗剤が混入されて洗浄水として被洗浄物9に噴射される。   When the operation is started from the operation panel provided in front of the installed dishwasher, the water supply valve 4 is opened and water or hot water supplied from the water supply pipe 18 passes through the stop cock 17, the water supply valve 4, and the water supply hose 3. Water is supplied into the cleaning tank 2. When the supplied water or hot water is stored in a predetermined amount at the bottom of the washing tank 2, the water supply valve 4 is closed, and the stored water is heated to an appropriate temperature by the heater 8 and at the same time the detergent is mixed into the washing water as washing water. It is injected to the object 9 to be cleaned.
洗浄水は図示しない洗浄ポンプによって洗浄ノズル7に供給され、回転する洗浄ノズル7から噴射される洗浄水は食器カゴ10に載せられた被処理物9に満遍なく噴射されて汚れが洗い出されて洗浄槽2の底部に戻るので、洗浄水の循環が繰り返されることによって被洗浄物9は洗浄される。洗浄によって生じた汚濁水は排水ポンプ12が起動されることによって排水ホース13から排水配管19に排出される。その後に給水弁4を開いて給水ホース3から洗浄槽2内に導入した水を用いてすすぎ洗いがなされることにより被洗浄物9の洗浄が完了する。   The cleaning water is supplied to the cleaning nozzle 7 by a cleaning pump (not shown), and the cleaning water sprayed from the rotating cleaning nozzle 7 is evenly sprayed on the workpiece 9 placed on the tableware basket 10 to wash out dirt. Since it returns to the bottom part of the tank 2, the to-be-cleaned object 9 is wash | cleaned by repeating circulation of wash water. The polluted water generated by the cleaning is discharged from the drain hose 13 to the drain pipe 19 when the drain pump 12 is started. Thereafter, the water supply valve 4 is opened, and rinsing is performed using the water introduced into the cleaning tank 2 from the water supply hose 3, thereby completing the cleaning of the object 9 to be cleaned.
上記構成において、従来技術において筺体5内に配設されていた給水弁4が給水配管18の近傍位置に配設されていることに注目されたい。このように給水弁4を給水配管18の近傍位置に配設することにより、給水弁4が開かれて洗浄槽2内に給水がなされているとき以外は、給水弁4より下流側には水流や水圧が生じないので、仮に給水ホース3の接続箇所に不具合があったり、給水ホース3に損傷があっても漏水の発生は最小限に抑えられる。また、食器洗い機が使用されていない状態では、漏水の発生は生じないことになる。   In the above configuration, it should be noted that the water supply valve 4 disposed in the housing 5 in the prior art is disposed in the vicinity of the water supply pipe 18. By disposing the water supply valve 4 in the vicinity of the water supply pipe 18 in this way, a water flow is provided downstream of the water supply valve 4 except when the water supply valve 4 is opened and water is supplied into the cleaning tank 2. Since no water pressure is generated, the occurrence of water leakage can be suppressed to a minimum even if there is a problem in the connection portion of the water supply hose 3 or the water supply hose 3 is damaged. Moreover, when the dishwasher is not used, the occurrence of water leakage does not occur.
前述したように、食器洗い機はその設置に際して給水及び排水の管路接続が不可欠であり、設置工事は工事業者の手に委ねられるので、食器洗い機が正常に機能していても設置工事に不備があると、食器洗い機に不具合が生じることになる。特に、給水の管路接続に不備があると、常時水圧が加わる給水管路では漏水という建物に被害を与えかねない問題が発生する。従って、管路接続の不備があっても、それに伴う被害の発生を最小限に抑える対策を講じておくことが必要であり、上記構成のように給水弁4を給水配管18との接続部位に配置することにより、管路接続に不備があっても漏水の発生は最小限に抑えられる。   As mentioned above, it is indispensable to connect the water supply and drainage pipes for installation of the dishwasher, and the installation work is left to the contractor's hands, so there is a deficiency in the installation work even if the dishwasher functions normally. If so, the dishwasher will fail. In particular, if there is a deficiency in the connection of the water supply pipeline, there will be a problem that water leakage may cause damage to the building in the water supply pipeline where water pressure is constantly applied. Therefore, it is necessary to take measures for minimizing the occurrence of damage caused by the lack of pipe connection, and the water supply valve 4 is connected to the water supply pipe 18 as in the above configuration. By arranging it, the occurrence of water leakage can be minimized even if the pipe connection is incomplete.
また、図2に示すように、給水弁4に漏水センサ(漏水検知手段)22を設けておくと、給水弁4と給水ホース3との接続箇所あるいは給水弁4と止水栓17との接続箇所に不具合が生じて漏水が生じた場合にも、漏水の発生を速やかに使用者に報知することができる。更に、漏水センサ22を止水栓17に設けることにより、より上流側で漏水検知を行うことが可能である。   In addition, as shown in FIG. 2, if a water leakage sensor (water leakage detection means) 22 is provided in the water supply valve 4, the connection between the water supply valve 4 and the water supply hose 3 or the connection between the water supply valve 4 and the water stop cock 17. Even when a malfunction occurs at a location and a water leak occurs, the user can be immediately notified of the occurrence of the water leak. Furthermore, by providing the water leakage sensor 22 in the water stop cock 17, it is possible to detect water leakage more upstream.
より望ましくは、図3に示すように、給水弁4及び止水栓17に対応する位置に漏水センサ22を設けると、最も漏水発生の原因となりやすい給水ホース3と給水配管18との接続管路での漏水を検知することが可能となる。   More desirably, as shown in FIG. 3, when a water leakage sensor 22 is provided at a position corresponding to the water supply valve 4 and the water stop cock 17, a connection line between the water supply hose 3 and the water supply pipe 18 that is most likely to cause water leakage. It is possible to detect water leakage at
図3において、給水ホース3の端部は給水弁4のホース接続筒4bの外周上に圧入され、図示しないホースバンド等の締結部材によって位置固定されている。給水配管18の端部には止水栓17が設けられているので、そのネジ口17aに給水弁4の連結筒4aをリング状のシール部材29を介して衝き合わせ、配管接続部材16をネジ口17aに螺合させていくと、配管接続部材16によって連結筒4aの鍔部が止水栓17側に押し付けられるので、シール部材29は圧縮されて止水栓17と給水弁4とは水密構造に連結される。この接続構造により、給水配管18から給水弁4、給水ホース3を通じた洗浄槽2への給水管路が形成される。   In FIG. 3, the end of the water supply hose 3 is press-fitted onto the outer periphery of the hose connection tube 4b of the water supply valve 4 and is fixed in position by a fastening member such as a hose band (not shown). Since the water stop cock 17 is provided at the end of the water supply pipe 18, the connecting cylinder 4 a of the water supply valve 4 is abutted against the screw port 17 a via the ring-shaped seal member 29, and the pipe connection member 16 is screwed. When screwed into the port 17a, the flange portion of the connecting tube 4a is pressed against the stop cock 17 side by the pipe connecting member 16, so that the seal member 29 is compressed and the stop cock 17 and the water supply valve 4 are watertight. Connected to the structure. With this connection structure, a water supply pipe line from the water supply pipe 18 to the cleaning tank 2 through the water supply valve 4 and the water supply hose 3 is formed.
この管路接続部位の下に、図示するように水受容器31を配し、その中に漏水センサ22を設けておくと、管路接続の不備に伴う漏水や止水栓17からの漏水があると、漏水した水は水受容器31内に落ちるので、漏水センサ22により漏水が速やかに検知される。図3において、水受容器31の上方を覆う上蓋32は、水受容器31内に水や異物、塵埃等が浸入して漏水センサ22が誤動作することを防止するのに有効である。止水栓17は食器洗い機の設置が完了した後では操作する必要はないが、設置工事中の試運転や点検、修理等を行う際には、給水を開閉する操作を行う必要がある。そのため、止水栓17を被覆する上蓋は、その取り外しが容易にできるように構成することが望ましいものとなる。   If a water receiver 31 is arranged under the pipe connection portion as shown in the figure and a water leak sensor 22 is provided therein, water leaks due to poor pipe connection or water leak from the stop cock 17 will occur. If there is, the leaked water falls into the water receiver 31, so that the leak is detected quickly by the leak sensor 22. In FIG. 3, the upper lid 32 covering the upper side of the water receiver 31 is effective in preventing water, foreign matter, dust and the like from entering the water receiver 31 and malfunctioning of the water leakage sensor 22. The stop cock 17 does not need to be operated after the installation of the dishwasher is completed, but it is necessary to open and close the water supply when performing a trial run, inspection, repair, etc. during the installation work. Therefore, it is desirable that the upper lid that covers the water stop cock 17 is configured so that it can be easily removed.
尚、従来技術においても実施されているように、筺体5の下部にも漏水センサ15を設けておくことが望ましく、洗浄槽2や給水ホース3の洗浄槽2への接続箇所などから漏水があった場合にも漏水を検知することができ、漏水した水が筺体5から床面に流れ出る以前に検知することができる。   As is also practiced in the prior art, it is desirable to provide a water leakage sensor 15 at the lower part of the housing 5, and there is water leakage from the connection location of the cleaning tank 2 and the water supply hose 3 to the cleaning tank 2. In such a case, water leakage can be detected, and can be detected before the leaked water flows from the housing 5 to the floor.
以上の説明の通り本発明によれば、設置に際して給水及び排水のための管路接続工事が伴う食器洗い機の設置工事に不備があった場合においても、給水弁を給水配管との接続部位に配置しているので、漏水の発生を最小限に抑えることができ、漏水検知手段の配置によって漏水の発生を速やかに検知する食器洗い機を提供することができる。   As described above, according to the present invention, even when there is a deficiency in the installation work of the dishwasher accompanied by the pipe connection work for water supply and drainage at the time of installation, the water supply valve is arranged at the connection part with the water supply pipe Therefore, it is possible to provide a dishwasher that can minimize the occurrence of water leakage and can quickly detect the occurrence of water leakage by arranging the water leakage detection means.
