Description

【0001】
【発明の属する技術分野】
本発明は、水を浄水し供給する浄水給水器及び該浄水給水器を備えた蒸気発生器に関するものである
【0002】
【従来の技術】
従来、食品の湿度を保った調理を行うために用いられる蒸気発生手段を備えた調理器や、室内の空気を加湿するために用いられる加湿器においては、水道水を使用して水蒸気を発生させている。この際、水道水中に含まれるカルシウムやマグネシウムなどのミネラル分が主に炭酸塩となって析出する。これが蒸気発生手段や水蒸気導出通路にスケールとして堆積し、蒸気発生手段の熱伝導効率が低下したり、水蒸気導出通路を詰まらせるという問題点があった。このため、長期間使用する時は、堆積したスケールを定期的に除去する作業が必要となるが、このスケールは強固に付着しているため除去が困難であった。
【0003】
そこで、従来よりイオン交換樹脂を用いてミネラル分を除去する方法が提案されており、例えば特開平10−103720号、特開平10−337572号、特開2001−4176号公報等において、水を収容する容器内部又は外部にイオン交換樹脂等を使用した浄水ユニットを着脱自在に設け、水道水からミネラル分を除去することにより、スケールの発生を防止する加湿器が開示されている。

【発明が解決しようとする課題】
上記の従来技術においては、水を収容する給水容器の内部にイオン交換樹脂等の浄水剤から構成される浄水ユニットを着脱自在に設置したものであり、何れも浄水剤を保持し、給水容器の水を浄水ユニットに通水するために、浄水ユニットの上流側及び下流側に浄水剤の粒径よりも小さな細孔を有するメッシュ状のフィルターを配置している。一般的に、浄水剤の浄水性能は表面積が大きくなるほど高くなるため、浄水剤の粒径が小さいほど好ましい。そのため、フィルターの細孔も浄水剤の粒径に併せて小さくする必要があるが、フィルターの細孔が小さくなるとフィルター上部に存在する水の圧力により、空気がフィルターを通過しにくくなる。つまり、給水容器の水を浄水ユニットへ円滑に通水できないという問題点があった。
【0006】
【課題を解決するための手段】
上記目的を達成するため、本発明は、水を収容し給水する給水部と、該給水部の下方に位置し前記給水部より給水された水を浄水する浄水ユニットと、該浄水ユニットにより浄水された水を外部に給水する給水口とを密閉容器に備えてなる浄水給水器において、前記給水口の上方に位置し前記給水口からの給水に伴って流入した空気を前記給水部の上部に導入する空気導入経路を備え、前記給水口からの給水に伴って流入した空気が前記浄水ユニットを通過することなく前記給水部の上部に導入されるようにしたことを特徴とするものである。
【0007】
この構成によると、浄水した水を給水口から外部へ給水する際、空気は給水口からの給水に伴って空気導入経路を介して給水部の上部に導入される。そのため、空気は浄水剤の保持及び通水のために使用するフィルターを通過する必要がなく、給水部より浄水ユニットへ円滑な水の供給が可能となる。
【0008】
また本発明は、上記構成の浄水給水器において、前記空気導入経路の上部に位置し前記空気導入経路の空気を前記給水部に導入する空気口を前記給水部より高い位置に設ける構成とした。これにより、密閉容器内へ水を供給する際に水位レベルを気にせず供給できる。
【0009】
また本発明は、上記構成の浄水給水器において、前記給水口の内部に開閉弁を備える構成とした。これにより、必要に応じて給水口を開閉することが可能となり、浄水給水器を着脱式とした場合の取り扱いが容易になる。
【0010】
また本発明は、上記構成の浄水給水器において、前記空気口に開閉弁を設け、前記給水口の開閉弁と前記空気口の開閉弁を一体化することとした。これにより、給水部の水が空気口から空気導入経路内へ溢れ、浄水ユニットを通過せずに給水口へ流れることを防止できる。また、給水口の開閉弁を開口するだけで給水部に空気を導入することができ、円滑な給水が可能となる。
【0011】
また本発明は、上記構成の浄水給水器において、前記密閉容器上部に着脱可能な上蓋を設け、該上蓋の内面部に前記空気口の開閉弁を前記給水口の開閉弁とは別個に設けることとした。これにより、上蓋の脱着によって空気口の開閉弁も脱着可能となり、空気口の開閉弁の清掃や交換等のメンテナンスも容易となる。
【0012】
また本発明は、上記構成の浄水給水器が装着される蒸気発生器において、浄水給水器の前記給水口が挿入される部分に突部を設け、該突部により前記給水口の開閉弁を開口することとした。この構成によると、浄水給水器の給水口を受口に装着したとき以外は給水口から水が流出せず、蒸気発生器からの浄水給水器の着脱が容易となる。更に、浄水された水を蒸気発生器に供給することにより、蒸気発生手段や水蒸気導出通路でのスケールの堆積が抑制される蒸気発生器を提供することができる。
【0013】
【発明の実施の形態】
以下に本発明の第1実施例を図面を参照して説明する。図1は本発明の浄水給水器を示す模式図である。図1において、1は浄水給水器であり、上部には開閉可能な上蓋4が設けられている。上蓋4の中央部には浄水給水器1内に水を供給する供給口3が設けられ、キャップ13により開閉自在に構成されている。これにより、浄水給水器1は開閉自在な密閉容器となっている。浄水給水器1の内部上方には給水部5が設けられ、給水部5の下方に位置する浄水ユニット6に水を給水する。2は浄水ユニット6により浄水された水を外部に給水する給水口であり、給水口2の上方には空気導入経路7を介して空気口8が設けられている。
【0014】
10、11は給水口2及び空気口8の水及び空気の流出及び流入を制御する断面が三日月状の開閉弁であり、空気導入経路7内を貫通する弁棒12の両端に固定されている。14、15は夫々給水口2及び空気導入経路7内に固定された弁棒12の支持部材であり、弁棒12の直径よりも大きいガイド穴(図示せず)を備えている。9は開閉弁10、11を閉動作方向に付勢するスプリングであり、弁棒12はスプリング9及び支持部材14、15のガイド穴を貫通し空気導入経路7内において上下に摺動可能に支持されている。本実施例における支持部材14、15はガイド穴を弁棒12が貫通する構成としたが、弁棒12を上下に摺動可能に支持できるものであればこれに限定されるものではない。また、支持部材は2箇所配置したが、支持部材の数は任意に設定可能である。
【0015】
開閉弁10の開閉する仕組みを図2により詳細に説明する。図2は浄水給水器1の給水口2付近の断面拡大図である。図において、支持部材14は給水口2内において図面の表裏方向に対峙する壁面の少なくとも一方に固定されており、弁棒12を支持するガイド穴14aを備えている。なお、図示しないが支持部材15も支持部材14と同様に構成されている。支持部材14と図面の左右方向に対峙する壁面2aとの間には浄水された水が通水する隙間39が設けられている。弁棒12はスプリング9及び支持部材14(及び支持部材15)のガイド穴14aを貫通し、上下に摺動可能に支持されており、支持部材14を挟んでスプリング9と反対側には開閉弁10が固定されている。弁棒12の下端にはスプリング9の直径より大きい径大部12aが設けられ、スプリング9は弁棒12の径大部12aと支持部材14の間に狭着されている。
【0016】
通常の状態では図2(a)に示すようにスプリング9の弾性力により弁棒12が下へ押し下げられるため、弁棒12に固定された開閉弁10は給水口2内部に押しつけられ、給水口2は閉口となっている。次に、浄水給水器1を後述する突部21を有する水供給通路20へ装着するなどして弁棒12が上へ押し上げられた場合、図2(b)に示すように押圧によりスプリング9が収縮し、弁棒12と共に開閉弁10も上へ上がるため、給水口2は開口する。更に、浄水給水器1を水供給通路20から取り外すと、突部21によりスプリング9にかかる押圧が無くなるため再び図2(a)の状態に戻り、給水口2は閉口する。
【0017】
スプリング9を配置しなくても開閉弁10は重力により給水口2を閉じることが可能であるが、浄水給水器1を取り外す際、給水口2より水が漏れないよう開閉弁10の閉動作を俊敏に行う必要がある。また、軟水給水器1単体で移動等する場合、振動や衝撃などにより開閉弁10が上へ上がり、給水口2が開いてしまうおそれもある。このようにスプリング9を配置することにより開閉弁10の閉動作を俊敏かつ確実なものとし、弁棒12及び開閉弁10の不必要な動きを防止することができ、浄水給水器1の取り扱いが容易となる。なお、ここでは開閉弁10についてのみ説明を行ったが、開閉弁11も同様の仕組みにより開閉弁10に連動して空気口8を開閉する。これにより、給水口2を開口するだけで空気口8も自動的に開口され、空気口8を介して空気が給水部5に導入されるため給水部5より浄水ユニット6へ円滑に水を供給できる。
【0018】
16は浄水剤であり、浄水ユニット6の内部に収容されている。浄水剤としては種々のイオン交換樹脂等が用いられるが、殺菌性イオン交換樹脂又はイオン交換樹脂と殺菌剤との混合物等を使用すると浄水給水器1内での雑菌の繁殖が抑制されるためより好ましい。浄水ユニット6の上面すなわち浄水順路の上流側、及び浄水ユニット6の底面すなわち浄水順路の下流側にはメッシュ状のフィルター17、18が浄水ユニット6の上面及び底面の少なくとも一部を覆うように設けられている。フィルター17、18は浄水剤16を保持し、給水部5の水を浄水剤16へ通水するため、浄水剤16の粒径よりも細かいメッシュのものが用いられる。更に、浄水ユニット6はオーリング等のシール材19により浄水給水器1の内部でシールされており、上方の給水部5の水は全て浄水ユニット6を通過し下方へ流れる。
【0019】
次に、本発明の浄水給水器の動作について説明する。先ず、キャップ13を取り、供給口3から給水し、再びキャップ13を閉める。このとき、空気口8の開口時に水が空気導入経路7内へ溢れることがないように空気口8より下位レベルまで給水するものとする。浄水給水器1単体では開閉弁10はスプリング9の弾性力により給水口2を閉口しているため(図2(a)参照)、この時点では外部への水の流出はない。次に、浄水給水器1を内部に突部21が設けられた水供給通路20へ装着するなどして、浄水給水器1の弁棒12が押し上げられると、給水口2の開閉弁10及び空気口8の開閉弁11が開口する(図2(b)参照)。これにより、浄水された水が給水口2から水供給通路20に給水されると共に給水に伴って流入した空気が空気導入経路7及び空気口8を通って給水部5に導入され、給水部5内の水が浄水ユニット6の上流側フィルター17、浄水剤16、下流側フィルター18を順次通過し浄水される。このようにして浄水された水は給水口2を通り、水供給通路20を介して外部へ供給される。
【0020】
また、長期間の使用により浄水ユニット6内の浄水剤16の浄水性能が低下した場合、上蓋4を外し、浄水ユニット6の上部に設けられた取手22を持って浄水ユニット6を取り外すことができる。取り外した浄水ユニット6は別途用意した容器に入れ塩水に浸漬して再生するか、新しい浄水ユニットと交換する。これにより、浄水ユニット6のメンテナンスが容易となる。また、給水口2の一部又は全部を着脱可能とすることもできる。この場合、開閉弁10の清掃、交換及び浄水給水器内部の清掃も容易となり、更にメンテナンス性が向上する。
【0021】
次に本発明の第2実施例を図面を参照して説明する。図3は本発明の浄水給水器を示す模式図であり、第1実施例の浄水給水器において給水口2の開閉弁10と空気口8の開閉弁11が夫々独立して構成されている。浄水給水器1のその他の構成及び動作は第1実施例と共通するため、説明を省略する。上蓋4の内面には空気口8の開閉弁11を支持する支持部24が設けられ、支持部24の内部にはスプリング26及びスプリング26を支持するスプリング支持材25が備えられている。弁棒12の上部には第二弁棒27が設けられ、開閉弁11が固定されている。第二弁棒27の上端はスプリング支持材25に固定され、スプリング支持材25は支持部24内で上下に摺動可能に支持されている。
【0022】
本実施例の開閉弁11の開閉する仕組みを図4により詳細に説明する。図4は第2実施例における空気口8付近の断面拡大図である。スプリング26は両端部がそれぞれ上蓋4の内面及びスプリング支持材25の内部上面に当接している。軟水給水器1単体では図4(a)に示すようにスプリング支持材25及びスプリング支持材25に固定された第二弁棒27はスプリング26の弾性力により下へ押し下げられているため、第二弁棒27に固定された開閉弁11は空気口8に押しつけられ、空気口8は閉口となっている。
【0023】
次に、浄水給水器1が突部21を有する水供給通路20へ装着されるなどして弁棒12が上へ押し上げられた場合、図4(b)に示すように第二弁棒27の下端の径大部27aが弁棒12の上端部により押し上げられ、同時にスプリング支持材25も押し上げられる。このとき押圧によりスプリング26が収縮するため、第二弁棒27と共に開閉弁11も上へ上がり、空気口8は開口する。弁棒12の下部には給水口2の開閉弁10が固定されており、突部21により弁棒12が押し上げられると図2(b)に示したように給水口2が開口するため、給水口2の開口と連動して空気口8も開口する。そして浄水給水器1が再び取り外され、突部21による圧力が無くなった場合は給水口2の閉口と連動して空気口8も閉口する。また、上蓋4を取り外した際、開閉弁11も取り外すことができるため開閉弁11の清掃、交換等のメンテナンス性が向上する。
【0024】
次に本発明の第3実施例を図面を参照して説明する。図5は本発明の浄水給水器を示す模式図であり、第1実施例の浄水給水器において給水部5よりも高い位置に空気口8を設けたものである。浄水給水器1のその他の構成及び動作は第1実施例と共通するため、説明を省略する。この構成では、浄水給水器1に供給口3より水を供給する際、給水部5の上限まで水を供給しても空気口8が開口する際に水が空気導入経路7内に溢れることがないため、給水レベルを気にすることなく水を供給することができる。
【0025】
次に本発明の第4実施例を図面を参照して説明する。図6は本発明の浄水給水器を示す模式図であり、第1実施例の浄水給水器において上蓋4の一部を開閉自在としたものである。浄水給水器1のその他の構成及び動作は第1実施例と共通するため、説明を省略する。この構成では、供給口3及びキャップ13を設けなくとも上蓋の一部を開くことにより浄水給水器1への給水が可能となるため、浄水給水器の外観を簡素化することができる。なお、以上の各実施例は用途及び目的に応じて適宜組み合わせて使用できるのは勿論のことである。
【0026】
次に、本発明の浄水給水器を備えた蒸気発生器について説明する。図7は本発明の浄水給水器を利用した蒸気発生器の模式図である。20は内部に突部21を備えた水供給通路であり、本発明の浄水給水器1が装着される。このとき突部21によって浄水給水器1の弁棒12が押し上げられ、開閉弁10により給水口2が開口されて浄水された水が給水口2から水供給通路20内に供給される。供給された水は、水供給通路20内を通って蒸気発生手段29へ流れる。30は蒸気発生手段29の外周に巻き付けられたヒーターであり、通電により蒸気発生手段29内の水を加熱し、蒸気を発生させる。発生した蒸気は蒸気発生口32から外部に供給される。31は蒸気発生手段29内の水位レベルより上部に設けられた突沸防止板であり、煮沸音を静音化し、蒸気発生口32からの外部への熱水の飛び出しを抑制する。28は水供給通路20内の水位レベルにより作動するフロートセンサであり、水供給通路20および蒸気発生手段29内の水が枯渇する前にヒーター30の通電を停止し、空焚きを防止する。
【0027】
ヒーター30は本実施例のように蒸気発生手段29の外周に巻き付けたものでも良いが、内部に浸漬する投げ込みヒーターとしても良い。また、ヒーターによる加熱方式に限らず、超音波振動子を利用した方式及びその他の方式による蒸気発生手段を用いても良い。
【0028】
また、蒸気発生器を調理などで使用する過熱水蒸気供給器として利用する場合、図8のように蒸気発生口32に更に過熱蒸気発生器33を接続し、過熱蒸気供給口34より過熱蒸気を供給することができる。過熱蒸気発生器33はヒーター35及び該ヒーター35の周囲に螺旋状に配置される金属メッシュ36から構成され、金属メッシュ36により効率よく蒸気を加熱し、過熱蒸気を生成する。
【0029】
また、本発明では蒸気発生器に用いられる浄水給水器を説明したが、本発明は水道水からミネラル分を除去する必要のある浄水給水器に有効であり、例えば飲料水用の浄水給水器にも適用できる。
【0030】
【発明の効果】
本発明によると、水を収容し給水する給水部と、該給水部の下方に位置し前記給水部より給水された水を浄水する浄水ユニットと、該浄水ユニットにより浄水された水を外部に給水する給水口とを密閉容器に備えてなる浄水給水器において、前記給水口の上方に位置し前記給水口からの給水に伴って流入した空気を前記給水部の上部に導入する空気導入経路を備え、前記給水口からの給水に伴って流入した空気が前記浄水ユニットを通過することなく前記給水部の上部に導入されるようにしたため、給水部より浄水ユニットへの円滑な給水が可能となる。
【0031】
また、空気口を給水部より高い位置に設置することにより、空気口の開口時に水が空気導入経路内に溢れることがないため浄水給水器内へ水を供給する際に水位レベルを制限する必要がない。
【0032】
また、給水口に開閉弁を設けたことにより、浄水給水器を着脱式とした場合の取り扱いが容易になる。
【0033】
また、空気口に開閉弁を設け、前記給水口の開閉弁と前記空気口の開閉弁を一体化したことにより、給水部の水が空気口から空気導入経路内へ溢れ、浄水ユニットを通過せずに給水口へ流れることを防止でき、給水口を開口するだけで浄水ユニットへ円滑に水を供給できる。
【0034】
また、上部に着脱可能な上蓋を設け、該上蓋の内面部に前記空気口の開閉弁を前記給水口の開閉弁と別個に設けたことにより、上蓋の脱着によって空気口の開閉弁も脱着可能となり、空気口の開閉弁の清掃や交換等のメンテナンスも容易となる。
【0035】
また、浄水給水器が装着される蒸気発生器において、浄水給水器の給水口が挿入される部分に突部を設け、該突部により給水口の開閉弁を開口することとしたため、浄水給水器の給水口を受口に装着したとき以外は給水口から水が流出せず、蒸気発生器からの浄水給水器の着脱が容易となる。更に、浄水された水を蒸気発生器に供給することにより、蒸気発生手段や水蒸気導出通路でのスケールの堆積を抑制できる蒸気発生器を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a water purifier for purifying and supplying water, and a steam generator provided with the water purifier.
[Prior art]
Conventionally, in a cooker equipped with a steam generating means used to cook food while keeping the humidity, or in a humidifier used to humidify indoor air, tap water is used to generate steam. ing. At this time, minerals such as calcium and magnesium contained in the tap water mainly precipitate as carbonates. This deposits as a scale on the steam generating means and the steam outlet passage, and causes a problem that the heat transfer efficiency of the steam generating unit is reduced and the steam outlet passage is clogged. For this reason, when used for a long period of time, it is necessary to periodically remove the deposited scale, but it is difficult to remove the scale because it is firmly attached.
[0003]
Therefore, a method of removing a mineral component by using an ion exchange resin has been conventionally proposed. For example, in Japanese Patent Application Laid-Open Nos. 10-103720, 10-337572, and 2001-4176, water is contained. There is disclosed a humidifier in which a water purification unit using an ion exchange resin or the like is detachably provided inside or outside a container to be removed, and a mineral component is removed from tap water to prevent scale from being generated.

JP 10-337572 A [Patent Document 3]
JP 2001-4176 A
[Problems to be solved by the invention]
In the above prior art, a water purification unit composed of a water purification agent such as an ion exchange resin is detachably installed inside a water supply container containing water, and both hold the water purification agent and form a water supply container. In order to pass water through the water purification unit, mesh filters having pores smaller than the particle size of the water purification agent are arranged on the upstream and downstream sides of the water purification unit. Generally, the water purification performance of a water purification agent increases as the surface area increases, and therefore, the smaller the particle size of the water purification agent, the better. Therefore, the pores of the filter also need to be reduced in accordance with the particle size of the water purification agent. However, when the pores of the filter become smaller, the air becomes difficult to pass through the filter due to the pressure of the water present above the filter. That is, there was a problem that the water in the water supply container could not be smoothly passed to the water purification unit.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a water supply unit for containing and supplying water, a water purification unit located below the water supply unit and purifying water supplied from the water supply unit, and water purified by the water purification unit. And a water supply port for supplying water to the outside in a closed container, wherein air introduced above the water supply port and introduced with water supplied from the water supply port is introduced into the upper part of the water supply section. An air introduction path is provided so that the air flowing in with the water supply from the water supply port is introduced into the upper part of the water supply part without passing through the water purification unit.
[0007]
According to this configuration, when the purified water is supplied from the water supply port to the outside, the air is introduced into the upper part of the water supply unit via the air introduction path along with the water supply from the water supply port. Therefore, it is not necessary for the air to pass through a filter used for holding and purifying the water purifying agent, and the water can be smoothly supplied from the water supply unit to the water purifying unit.
[0008]
Further, the present invention is configured such that in the water purifier with the above configuration, an air port located above the air introduction path and introducing air in the air introduction path to the water supply section is provided at a position higher than the water supply section. Thus, when supplying water into the closed container, the water can be supplied without concern for the water level.
[0009]
Further, the present invention is configured such that the water purifier having the above-mentioned configuration is provided with an on-off valve inside the water supply port. This makes it possible to open and close the water supply port as needed, and facilitates handling when the water purifier is detachable.
[0010]
Further, in the present invention, in the water purifier with the above configuration, an on-off valve is provided at the air port, and the on-off valve for the water supply port and the on-off valve for the air port are integrated. This can prevent the water in the water supply section from overflowing from the air port into the air introduction path and flowing to the water supply port without passing through the water purification unit. In addition, air can be introduced into the water supply section only by opening the on-off valve of the water supply port, and smooth water supply is possible.
[0011]
Further, the present invention, in the water purifier with the above configuration, a removable upper lid is provided on the upper portion of the closed container, and an open / close valve for the air port is provided on an inner surface portion of the upper lid separately from the open / close valve for the water supply port.

In the present embodiment, the support members 14 and 15 are configured such that the valve stem 12 penetrates the guide hole. However, the present invention is not limited to this as long as the valve stem 12 can be slidably supported up and down. Although the support members are arranged at two places, the number of the support members can be set arbitrarily.
[0015]
The mechanism for opening and closing the on-off valve 10 will be described in detail with reference to FIG. FIG. 2 is an enlarged cross-sectional view of the vicinity of the water supply port 2 of the water purifier 1. In the drawing, a support member 14 is fixed to at least one of the wall surfaces facing in the front and back directions in the drawing in the water supply port 2, and has a guide hole 14 a for supporting the valve stem 12.
