Description

【0001】
【発明の属する技術分野】
この発明は貯湯タンクユニットに関するものである。
【0002】
【従来の技術】
従来よりこの種のものにおいては、特許文献1に開示されたものがあり、これを図6に基づいて説明する。
101は貯湯タンクユニット本体、102はその内部に設けられ温水を貯湯する貯湯タンク、103は貯湯タンク102の上端に接続された出湯管、104は貯湯タンク102の下端に接続された給水管である。
【0003】
そして、貯湯タンクユニット本体101の底板105の前面側にて出湯管103および給水管104が外部配管と接続される配管接続部106が設けられているものである。
【0004】
【特許文献1】
意匠登録1050376号公報
【0005】
【発明が解決しようとする課題】
しかし、この従来のものでは、配管接続部106が器具の一番低い位置に設けられているため配管を接続する作業がしにくく、作業性が非常に悪いという課題があり、更に近年では給湯の他に暖房も行う多機能な貯湯タンクユニット本体が提供され、益々大きな配管スペースが必要となり、接続作業も複雑で手間のかかるものであった。
【0006】
【課題を解決するための手段】
そこで、本発明は前記課題を解決するため、請求項1では、温水を貯湯する貯湯タンクを有した貯湯タンクユニットに於いて、この貯湯タンクユニット前面側には外部配管と器具内配管とを接続する配管接続部を設け、この配管接続部は貯湯タンクの頂部と底部の間の高さに位置させ、その上方を器具内配管および機能部品を配置するスペースとし、又その下方を段差凹み部として外部配管を接続するスペースとすると共に、この段差凹み部の少なくとも一部を貯湯タンク外周に概ね沿わせた形状の斜めカット部を形成し、ここを暖房配管接続部としたものである。
【0007】
又請求項2では、暖房配管接続部は、往きヘッダーと戻りヘッダーとで構成されているものである。
更に請求項3では、斜めカット部で、循環ポンプ等の重量機能部品取り付け部と対向する位置には、補強金具が備えられ、この補強金具には往きヘッダー及び戻りヘッダーの一端を保持する保持部を形成したものである。
【0008】
これにより、往き、戻りと言う暖房配管特有の接続が専用の場所で行われるので、接続作業が容易に行われると共に、接続部分が前方に飛び出すことなくスッキリと収まるものであり、更に貯湯タンクを小さくすることなく外部配管を接続するスペースも大きくとれるため、狭い場所に貯湯タンクユニットを設置したとしても接続作業を行う手元空間を大きく確保することができ、接続する位置が高くなって作業者にムリな姿勢を強いることがなく、配管接続作業の作業性が大きく向上すると共に、外部配管を無理なく確実に接続することが出来る。又配管接続部の高さ位置を最適化したので作業者がしゃがんだ姿勢で容易に配管作業を行うことが出来ると共に、外部配管を真っ直ぐ確実に接続することが出来、接続部での液漏れを防ぐことが出来る。
【0009】
又暖房配管接続部を往きヘッダーと戻りヘッダーとで構成しても、斜めカット部であるから前方に飛び出す心配もなく確実に接続されるものであり、更に重量機能部品取り付け部の補強金具にヘッダーの保持部を設けたことで、補強と共にヘッダーの接続時の回動を防止して、接続の簡素化を図るものである。
【0010】
【発明の実施の形態】
次に、この発明の一実施形態を図面に基づいて説明する。
図1は概略構成図で、1は貯湯タンクユニット、2はヒートポンプユニットよりなる加熱部、3は給湯栓、4はリモートコントローラ、5は浴槽、6は電源である。
【0011】
前記貯湯タンクユニット1は、湯水を貯湯する貯湯タンク7と、貯湯タンク7の上部に接続された出湯管8と、貯湯タンク7の下部に接続された給水管9と、出湯管8からの高温水と給水管9から分岐されたバイパス管10からの低温水とを混合するミキシング弁11と、ミキシング弁11の下流に接続された給湯管12と、給湯管12に設けられた給湯温度センサ13と、給湯管11に設けられた給湯流量センサ14と、給水管8に設けられた給水温度センサ15と、給湯管12から分岐され浴槽5に接続された湯張り管16と、この湯張り管16の開閉を行う湯張り弁17と、湯張り管16を流れる流量を積算する湯張り流量センサ18と、出湯管8から分岐して接続された貯湯タンク7の過圧を逃す過圧逃し弁19と、給水管8に設けられた給水圧を減圧する減圧弁20と、貯湯タンク7の側面上下方向に複数設けられた貯湯温度センサ21と、この貯湯タンクユニット1の制御を行うマイクロコンピュータを主に構成される給湯制御部22と、貯湯タンク7と加熱部2とを接続して湯水を循環させる加熱循環回路23とを備えて構成されている。
【0012】
24は貯湯タンク7内上部の高温水を一次側ポンプ25の駆動で循環させ、二次側温水を加熱する暖房用熱交換器で、熱交換後の中温水は再び貯湯タンク7下部に戻すものであり、加熱された二次側温水は二次側ポンプ26の駆動によって、往き管27から床暖房等の放熱器28で暖房した後、温度降下した二次側温水は戻り管29から再び暖房用熱交換器24に戻され加熱されるという循環を順次繰り返すものである。
【0013】
前記加熱部2は、二酸化炭素冷媒を圧縮するコンプレッサー30と、凝縮器としての冷媒−水熱交換器31と、減圧器32と、蒸発器としての空気熱交換器33よりなるヒートポンプ回路34と、空気熱交換器33に送風する送風機35と、加熱循環回路23途中に設けられた能力可変の循環ポンプ36と、加熱循環回路23の冷媒−水熱交換器31入口側に設けられ、冷媒−水熱交換器31に流入する湯水の温度を検出する熱交入口温度センサ37と、加熱循環回路23の冷媒−水熱交換器31出口側に設けられ、冷媒−水熱交換器31から流出する湯水の温度を検出する熱交出口温度センサ38と、この加熱部2の制御を行うマイクロコンピュータを主に構成される加熱制御部39とを備えて構成されている。
【0014】
ここで、前記電源6は時間帯別電灯であり、夜間(ここでは23時から翌7時まで)が割安な電力料金設定となっているもので、この割安な夜間電力を用いて夜間に一日に必要な貯湯熱量を沸かし上げて使用するものであり、また、この時間帯別電灯では昼間(7時から23時まで)にも電力は供給され、残湯量が少なくなったときに追加の沸き増しが行われるものである。なお、前記電源6は給湯制御部22に接続され、この給湯制御部22からリモートコントローラ4および加熱制御部39(ヒートポンプ回路34に必要な電力を含む)に有線にて通信信号が重畳されて電力供給されるものである。
【0015】
そして、夜間時間帯になると前記給湯制御部22が翌日に必要な貯湯熱量を演算し、この目標となる貯湯熱量を夜間時間帯の終了時までに沸き上げるよう加熱制御部39に指示してヒートポンプ回路34を作動させ、加熱循環回路23の循環ポンプ36を駆動開始する。そして、循環ポンプ36の駆動により貯湯タンク7下部から取り出された湯水が加熱部2の冷媒−水熱交換器31に流入して加熱され、加熱循環回路23を介して貯湯タンク7の上部に戻されることにより高温の湯が貯湯される。
【0016】
そして、貯湯タンク7の側面に設けられた貯湯温度センサ21が所定の量の高温水が貯湯されたことを検出するか、または、熱交入口温度センサ37が所定温度以上を検出すると、給湯制御部22が加熱制御部39へ加熱動作の停止を指令し、ヒートポンプ回路34と循環ポンプ36の作動が停止され、夜間時間帯の終了時までに貯湯動作を終了するものである。
【0017】
なお、ここで、貯湯タンク7内に貯湯される熱量は給湯制御部22により過去数日分の給湯負荷から適切と思われる熱量を目標貯湯熱量として算出されるもので、貯湯される湯水の温度は季節(または給水温度センサ15で検出する給水温度)および目標貯湯熱量の大小によって60℃〜90℃の範囲で変動するものである。
【0018】
前記リモートコントローラ4には給湯設定温度を設定する温度設定スイッチ40、浴槽5への湯張りを指示する湯張りスイッチ41、湯張り量を設定する湯張り量設定スイッチ42、および給湯可能な残時間を表示させる残時間表示スイッチ43とを有した操作部44と、ドットマトリクス型の蛍光表示管よりなる表示部45と、これら操作部44および表示部45を制御すると共に、前記給湯制御部22と通信を行うマイクロコンピュータを主に構成されたリモコン制御部46を備えており、通常運転時は前記表示部45に操作部44で設定された給湯設定温度や時刻情報および貯湯温度センサ21で検知する残り貯湯量等が表示されるものである。なお、前記表示部45はドットマトリクス型の液晶表示部としてもよい。
【0019】
次に、給湯栓3を開くと、給水管9からの給水圧により貯湯タンク7上部の高温水が出湯管8に押し出され、給湯制御部22により制御されるミキシング弁11にてバイパス管10の低温水と給湯温度センサ13の検出する温度が前記リモートコントローラ4の操作部44で設定された給湯設定温度になるように混合されて給湯管12を介して給湯されるものである。
【0020】
もしも給湯量が通常よりも多くなってしまい、昼間電力時間帯にて貯湯温度センサ21で検出する残り貯湯量が少なくなったことを給湯制御部22が検知し、貯湯タンク7内に貯湯された湯の湯切れが予想される場合は、その時点にて昼間電力を利用して必要な熱量の沸き増しが行われるものである。
【0021】
次に、浴槽5に湯張りを行う際は、リモートコントローラ4の湯張りスイッチ41が操作されると、給湯制御部22が湯張り弁17を開いて湯張りを開始し、湯張りを開始してからの積算流量が湯張り量に達したことを検出すると湯張り弁17を閉じて湯張りを完了するものである。
【0022】
なお、前記加熱循環回路23の貯湯タンクユニット1側にはその途中に貯湯タンク7内の湯水を排水するための手動の排水栓47が設けられ、この排水栓47は貯湯タンクユニット1内の最下部に配置されているものである。
【0023】
ところで、前記貯湯タンクユニット1は、図2〜図5に示すように、ユニット筐体48の内部に貯湯タンク7、出湯管8、給水管9、加熱循環回路23の行き管及び帰り管、暖房用熱交換器24および往き管27、戻り管29等の器具内部の配管および前記ミキシング弁11や給湯制御部22や一次側、二次側ポンプ25、26等の機能部品が収納されて構成されている。
【0024】
そして、貯湯タンク7はユニット筐体48内の中心よりも後方側に配置され、この貯湯タンク7はタンク支持脚49によって支えられている。ユニット筐体48は前面パネル50、背面板51、左右の側面板52、53、天板54、および底板55より構成され、底板55よりも器具本体前面側の貯湯タンク7の頂部と底部の間の高さに位置に接続口取付板56が設けられ、接続口取付板56の下方を器具内側に後退させて段差凹み部57として外部配管を接続する空間とし、その上部がオーバーハングして前面パネル50および左右の側面板52、53の突出部分に囲まれた各機能部品および配管を収納する空間としているものである。
【0025】
前記接続口取付板56には、内部配管と外部配管とを各々接続する複数の継手58が設けられて配管接続部59を構成しているものである。この複数の継手58を介して器具内部の給水管9、給湯管12、湯張り管16、加熱循環路23等を器具外部の配管と接続するようにしていると共に、給湯制御部22と加熱制御部39およびリモコン制御部46と接続する通信配線(図示せず)を接続口取付板56に開口した穴(図示せず)に通しているものである。
【0026】
前記段差凹み部57は、少なくとも一部を貯湯タンク外周に概ね沿わせた形状の斜めカット部60を形成して外部配管を接続するスペースを大きく確保しているもので、ここでは、段差凹み部57の側方の一角を面取り形状とし、器具側方でのスペースがだんだんと大きくして暖房配管接続部61としており、正面に向かって暖房往き継手62及び暖房戻り継手63が備えられ、限られた横幅内で多数の配管を相互に余裕を持って配置することができると共に、配管接続作業を行う際の手元の空間が大きくなって作業性が大きく向上するものである。
【0027】
更にこの暖房配管接続部61には、複数の暖房箇所と接続される往きヘッダー64と、複数の暖房箇所からの戻りと接続される戻しヘッダー65とが、それぞれ暖房往き継手62及び暖房戻り継手63に接続されている。
【0028】
一方斜めカット部60の上方空間は角部で一番広いスペースとなるので、暖房用熱交換器24や一次側ポンプ25、二次側ポンプ26等の重量機能部品が取り付けられる重量機能部品取り付け部66とされることから、ここには上の重量機能部品を支える補強金具67が備えられており、この補強金具67は上の重量機能部品を支えるように斜めカット部60に垂直に固定され、その先端部には往きヘッダー64及び戻りヘッダー65の一端を保持する穴からなる保持部68が形成されており、各ヘッダー64、65の取り付け時の回り止めとなって、接続作業を更にやり易くするものである。
【0029】
これにより、段差凹み部57の大きなスペースを利用して給湯、給水と言う一般的な配管接続が楽に行われるものであり、更に奥に凹んだ斜めカット部60を暖房配管の専用接続部としたことで、配管を確認しながらの面倒な接続が極めて簡単に行えると共に、比較的大きなスペースを取る往きヘッダー64及び戻りヘッダー65を前面に出っ張らせることなく、スッキリと収納することが出来るものである。
又この各ヘッダー64、65の一端が、重量機能部品取り付け部66の補強を兼ねる補強金具67に保持され、固定時の回り止めとなるので、回り止め用の部品が不要で接続作業も簡単に行われるものである。
【0030】
なお、前記段差凹み部57には、貯湯タンクユニット1内の最下部に設けられた前記排水栓47に対応する位置に排水栓操作窓69が開口されていると共に、この排水栓操作窓70を覆う窓カバー71が着脱可能に取付けられている。ここで、前記配管接続部59の継手58は排水栓操作窓69の上方から横にずらされて排水栓操作窓69を避ける位置に設けられており、配管を接続した状態で窓カバー70を脱着して排水栓47の操作が可能となる。
【0031】
【発明の効果】
以上のようにこの発明によれば、貯湯タンクを小さくすることなく外部配管を接続するスペースが大きくとれるため、狭い場所に貯湯タンクユニットを設置したとしても接続作業を行う手元空間を大きく確保することができ、接続する位置が高くなって作業者にムリな姿勢を強いることがなく、配管接続作業の作業性が大きく向上すると共に、外部配管を無理なく確実に接続することができるという非常に優れた効果を奏するものである。
【0032】
更に段差凹み部の一角の奥に凹んだ斜めカット部を暖房配管の専用接続部としたことで、配管を確認しながらの面倒な接続が極めて簡単に行えると共に、比較的大きなスペースを取る往きヘッダー及び戻りヘッダーを前面に出っ張らせることなく、スッキリと収納することが出来るものである。
【0033】
又この各ヘッダーの一端が、重量機能部品取り付け部の補強を兼ねる補強金具に保持され、固定時の回り止めとなるので、回り止め用の部品が不要で接続作業も簡単に行われるものである。

[0004]
[Patent Document 1]
Design Registration No. 1050376
[Problems to be solved by the invention]
However, in this conventional apparatus, since the pipe connection portion 106 is provided at the lowest position of the appliance, it is difficult to connect the pipes, and there is a problem that workability is extremely poor. In addition, a multifunctional hot water storage tank unit for heating was provided, which required more and more piping space, and connection work was complicated and time-consuming.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention relates to a hot water storage tank unit having a hot water storage tank for storing hot water, wherein an external pipe and an instrument pipe are connected to a front side of the hot water tank unit. The pipe connection is provided at a height between the top and the bottom of the hot water storage tank, the space above it is used as a space for arranging pipes and functional parts in the appliance, and the space below the space is a step recess. In addition to providing a space for connecting the external piping, an oblique cut portion having a shape in which at least a part of the stepped concave portion is substantially along the outer periphery of the hot water storage tank is formed, and this is used as a heating piping connection portion.
