【発明の属する技術分野】
図4に従来の電気湯沸かし器の構造を示す。図において31は電気湯沸かし器の本体、32は底部に加熱装置であるヒータ33を備えた略円筒状の容器で、34は容器32の下方に位置して一端を容器32の底部の流出口35に連通し他端を移送管36に連通した送水装置である遠心ポンプである。37は容器32底面に備えた容器32内の湯温を検知する温度検知素子である。38は操作ボタンと表示部とを備えた操作部である。39はヒータ33と遠心ポンプ34とを操作部38からの信号で制御する制御回路である。
【0002】
以上のように構成した従来の電気湯沸かし器の動作を説明する。まず、容器32内に所定の水を給水する。電源をつなぐと制御回路39がヒータ33への通電を開始する。温度検知素子37が沸騰を検知すると制御回路39はヒータ33への通電を停止してやがて温度検知素子37からの信号でヒータ33への通電を制御しながら容器32内の湯を所定の温度に保温する。
【0003】
次に湯を所望の場合は、操作部38の操作ボタンを操作して制御回路39を介して遠心ポンプ34を駆動し容器32内の湯を移送管36を介して給湯する。所望の量を給湯すると操作ボタンの操作を停止して終了する。
【0004】
容器32内の水位は一般には移送管36を透明なガラス管で構成し移送管36が外方から見えるように構成して湯の量を確認して少なくなったら容器32内に人が給水する構造のものが一般的であった。
【0005】
【発明が解決しようとする課題】
しかしながら、前記従来の構成では、湯沸かし容器を貯水容器としても機能させていたために日常の1回に使う必要量(100ccから500cc程度)以上の数倍容量が大きく、多量の湯を貯めて置くことを必要とし、加熱した湯の必要量は少量の場合でも多量の貯め置き湯を常に加熱・保温することになり、無駄な電力を消費するといった課題があった。また、水を継ぎ足す際には、高温になった湯の飛散や蒸気等に注意を要するという課題も有していた。
【0006】
本発明は、前記従来の課題を解決するもので、貯水容器と湯沸かし容器を分割することで、総湯沸かし量は従来品と同等を確保しながらも一度に行う湯沸かしと保温量を減らし、小分けにすることで保温時の消費電力を抑え、また、独立した貯水容器を設けることで湯沸かし容器の状態に関係無く、手軽に安全に給水が行うことを目的とする。
【0007】

【0008】
これにより、総湯沸かし量は従来品と同等性能を確保しながらも一度に行う湯沸かし量や保温量を減らし、小分けにすることで保温時の消費電力を抑えることができる。また、着脱可能に独立した貯水容器を設けることで湯沸かし容器の状態に関係無く、手軽に給水が行える。

【0010】
湯沸かし容器と貯水容器を設けることにより総湯沸かし量あるいは総保温量を所定量確保しながら、一度に行う湯沸かし量や保温量を減らし、小分けにすることで保温時の消費電力を抑えることができる。また、独立して貯水容器を設けることで湯沸かし容器の状態に関係無く、手軽に給水が行える。また、供給路の途中に接続部を設け、接続部で分離及び接続することで貯水容器を前記湯沸かし容器に対して着脱自在としたことにより、貯水容器への給水あるいは容器の洗浄がさらに簡単に行えるものである。
【0011】
請求項2に記載の発明は、特に、供給路の途中に貯水容器から湯沸かし容器へ一方向にのみ液体を通過させる逆止弁を設けてなることにより、湯沸かし容器から貯水容器へと逆流する恐れがない。

【0013】
請求項4に記載の発明は、特に、供給路の湯沸かし容器に臨む部分である液体流入口は湯沸かし容器と貯水容器の満水面より上方に設けたことにより、湯沸かし容器と貯水容器の液面のヘッド差が原因で水が給水され続けるサイフォン現象が起こり、湯沸かし容器側の水が満水線を越えて溢れかえることを防止することができ、また湯沸かし容器に直接水を注いだ場合や湯の沸騰時に、湯沸かし容器内の水面が液体流入口付近まで上昇することがあったとしても、湯沸かし容器から貯水容器へ湯が逆流することを防ぐことができる。
【0014】
請求項5に記載の発明は、特に、液体流入口から自由落下または下り傾斜を利用して湯沸かし容器内に給水するように供給路を設けたことにより、水を最終的に自由落下で給水することでスムーズに湯沸かし容器内へ導くことができる。

【0016】
請求項7に記載の発明は、特に、液体流入口近傍に設けられるとともに湯沸かし容器の内壁面に沿って水を注水する液体誘導手段を備え、前記液体誘導手段か出湯路中のいずれかまたは両方に液体の質を改善する液体改質手段を設けたことにより、様々な物質の除去、添加が行える。
【0017】
【実施例】
(実施例1)
以下本発明の実施例1について、図1を参照しながら説明する。図1は本実施例の電気湯沸かし器の全体構成図である。
【0018】
図において、貯水容器1に収容されている水2は、貯水容器1の底部に設けられた液体流出口3から送水手段であるポンプ4へ導かれる。この水2は、ポンプ4により供給路5を通って、湯沸かし容器6の側面に設けられた液体流入口7から湯沸かし容器6内に給水される。ここで、液体流入口7は、湯沸かし容器6、貯水容器1の満水線より上部であれば良く、例えば湯沸かし容器6の上部を覆っている蓋にあっても良い。湯沸かし容器6内の水面が液体流入口7付近まで上昇した際に、貯水容器1から湯沸かし容器6への水2の流れ方向が、湯沸かし容器6側から貯水容器1側への方向とならないように逆止手段である逆止弁12が設けられている。
【0019】
湯沸かし容器6内に給水された水2は湯沸かし容器6の底部に設けられた加熱手段であるヒータ8によって、所望の温度まで加熱される。湯は必要に応じて出湯スイッチ17を押すことで出湯手段であるポンプ10を駆動し、出湯路11を通って本体20外に導出される。出湯路11中には、出湯スイッチ17と連動して弁が開き、湯沸かし容器6の転倒時等には流路を確実に閉塞する転倒流出防止弁18が設けられている。この転倒流出防止弁18は、湯沸かし容器6から出湯を所望しないときには確実に湯の流出が防止できる構造であれば良い。
【0020】
本体20外への導出により湯沸かし容器6内の湯が所定の量以下に低下すると、下側の水量センサー14bがこれを感知して、制御回路21はポンプ4を駆動させ、貯水容器1内の水2を湯沸かし容器6内に供給して、湯沸かし容器6内の水面が満水線まで上がったことを、上側の水量センサー14aにより感知し制御回路21はポンプ4の駆動を停止させて給水を停止する。
【0021】
貯水容器1と湯沸かし容器6は供給路5と液体流入口7の境界部分もしくは供給路5中に接続部16を設けており、ここで供給路5と湯沸かし容器6とを、もしくは供給路5相互を分離または接続することができる。接続部16は、図1に示すように供給路5と貯水容器1の境界部にある液体流出口3近傍に設けても良い。
【0022】
このような構成にすることで、総湯沸かし量は従来品と同等を確保しながらも一度に行う湯沸かし量や保温量を減らし、小分けにすることで保温時の消費電力を抑えることができる。また、独立した貯水容器1を設けることで湯沸かし容器6の状態に関係無く、手軽に給水が行える。また、また、二容器間を結ぶ供給路5中に止水弁19を設けることで、貯水容器1を取り外しても湯沸かし容器6からの湯の逆流を防ぐことができる。
【0023】
なお、本実施例では、本体20内に湯沸かし器6と貯水容器1を併設しているが、貯水容器1を本体20内部に設けず、本体20外部に装着する構成としても良い。この場合には貯水容器1内と本体20内に各々供給路5を有する、あるいは、貯水容器1の液体流出口3付近で本体20に設けた供給路5と接続すればよい。
【0024】
なお貯水容器1を取り外す別の方法として流体流出口3には、供給路5とスライドする水密な嵌め合い部分を設け、貯水容器1を上方へ持ち上げると流体流出口3の水通路が閉塞される弁を設け、それとともに供給路5側にも水通路が閉塞される弁を設けることにより貯水容器1を自由に着脱できる。
【0025】
また、供給路5の接続部16における接続は供給路の端面開口部の周囲に設けた弾力性を有する材料を介在させ一方の供給路の端面を他方の端面に押し当てて、水が漏れないように接続しても良い。
【0026】
このような構成とすることで、湯沸し容器6が湯沸かし・保温中の状態であっても、貯水容器1を取り外して給水を行ったり、貯水容器1の洗浄を行ったりすることができ、また、湯沸かし容器6については単独でも湯沸かし器として使用できる。
【0027】
送水装置であるポンプ4により供給路5を通って供給される水2は貯水容器1の満水線よりも高い位置に配置された液体流入口7から湯沸かし容器6内へと給水される。液体流入口7を貯水容器1側の満水線よりも上方に設置することで、二容器の液面のヘッド差が原因で水が給水され続けるサイフォン現象が起こり、湯沸かし容器6内の水が満水線を越えて溢れかえることを防止する。
【0028】
ポンプ4により湯沸かし容器6の満水線より高い位置に持ち上げられた水2は液体流入口7において自由落下を利用して湯沸かし容器6内へ給水される。
【0029】
この構成をすることで、湯沸かし容器6に直接水を注いだ場合や湯の沸騰時に、湯沸かし容器6内の水面が液体流入口7付近まで上昇することがあったとしても、湯沸かし容器6から貯水容器1へ湯が逆流することを防ぐことができ、また、水2を最終的に自由落下で給水することでスムーズに湯沸かし容器6内へ導くことができる。
【0030】
(実施例2)
図2は本発明の第2の実施例における液体誘導手段を示す要部断面図である。図において供給路5を通ってきた液体2は、液体流入口7近傍の湯沸かし容器6の内壁面側に設けられた液体誘導手段9により、湯沸かし容器6の内壁面へと誘導され、そのまま内壁面を伝って内部の水面へと注水される。
【0031】
この構造にすることで、液体流入口7から直接、放物線を描いて注水された場合と比べて、水2の飛び散りや注水時の音を減少させる。なお、液体誘導手段9は湯沸かし容器6を加工して設けてもよい。
【0032】
(実施例3)
図3は本発明の第3の実施例における液体誘導手段を示す要部断面図である。出湯路11中と,路液体流入口7部分には、貯水容器1内から給水された水2が改質手段15の内部に詰められている改質材であるミネラルボール21に触れることで水2にミネラル分が添加される構成の改質手段15が設けられている。
【0033】
この改質手段15としては、水2がミネラルボール21を通過することで不要な塩素分を取り除くことができる活性炭を内部に搭載する構成のものでも良い。また、この部分に多孔質状のメッシュフィルターを設置して、水2中の大きな粒子状の物質を取り除くことでも良い。
【0034】
この構成にすることで、様々な物質の除去、添加が行える。なお図3に示すように改質手段15のケースの一部に液体誘導手段9を一体にして設けてもよい。
【0035】
【発明の効果】
以上のように、本発明によれば、湯沸かし容器とは別に貯水容器を湯沸かし容器に対して着脱自在となるように設け、一度に行う湯沸かし量や保温量を減らし小分けにすることで保温時の消費電力を抑えるとともに手軽に給水が行える湯沸かし器を提供することができる。

The water reservoir 1 can be freely attached and detached by providing a valve and a valve for closing the water passage on the supply path 5 side together with the valve.
[0025]
Further, the connection at the connection portion 16 of the supply path 5 is performed by interposing an elastic material provided around the end face opening of the supply path and pressing the end face of one supply path against the other end face so that water does not leak. May be connected as follows.
[0026]
With such a configuration, the water storage container 1 can be removed to supply water, or the water storage container 1 can be washed, even when the water heater 6 is in the state of water heating and heat retention. The water heater 6 can be used alone as a water heater.
[0027]
Water 2 supplied through a supply path 5 by a pump 4 serving as a water supply device is supplied into a water heater 6 from a liquid inlet 7 arranged at a position higher than a full line of the water storage container 1. By installing the liquid inlet 7 above the water filling line on the water storage container 1 side, a siphon phenomenon in which water is continuously supplied due to a head difference between the liquid levels of the two containers occurs, and the water in the water heater container 6 becomes full. Prevents overflowing beyond the line.
[0028]
The water 2 lifted by the pump 4 to a position higher than the water filling line of the water heater 6 is supplied into the water heater 6 at the liquid inlet 7 by free fall.
[0029]
With this configuration, even if water is directly poured into the water heater 6 or when the water boils, even if the water level in the water heater 6 rises to near the liquid inlet 7, the water is stored from the water heater 6. Hot water can be prevented from flowing back to the container 1, and the water 2 can be smoothly introduced into the water heater 6 by finally supplying water 2 by free fall.
[0030]
(Example 2)
FIG. 2 is a sectional view of a main part showing a liquid guiding means according to a second embodiment of the present invention. In the figure, the liquid 2 that has passed through the supply path 5 is guided to the inner wall surface of the water heater 6 by the liquid guiding means 9 provided on the inner wall surface side of the water heater 6 near the liquid inlet 7, And water is poured into the water surface inside.
[0031]
With this structure, splashing of the water 2 and noise at the time of water injection are reduced as compared with the case where water is injected directly from the liquid inlet 7 in a parabolic manner. The liquid guiding means 9 may be provided by processing the kettle 6.
[0032]
(Example 3)
FIG. 3 is a sectional view showing a main part of a liquid guiding means according to a third embodiment of the present invention. The water 2 supplied from the inside of the water storage tank 1 is brought into contact with the mineral balls 21 as a reforming material packed in the reforming means 15 in the hot water path 11 and in the path liquid inlet 7. 2 is provided with a reforming means 15 configured to add a mineral component.
[0033]
The reforming means 15 may have a configuration in which activated carbon capable of removing unnecessary chlorine content by passing the water 2 through the mineral balls 21 is mounted inside. Alternatively, a porous mesh filter may be provided in this portion to remove large particulate matter in the water 2.
[0034]
With this configuration, various substances can be removed and added. As shown in FIG. 3, the liquid guiding means 9 may be provided integrally with a part of the case of the reforming means 15.
[0035]
【The invention's effect】
As described above, according to the present invention, the water storage container is provided separately from the water heater container so as to be detachable from the water heater container, and the amount of water heating and the heat retention amount performed at a time are reduced and subdivided so that the water retention time can be reduced. A water heater capable of suppressing power consumption and easily supplying water can be provided.
