Description

【０００１】
【発明の属する技術分野】
本発明は、ヒートポンプ式の空気調和機に係り、特に、蓄熱容器を備えた空気調和機に関する。
【０００２】
【従来の技術】
通常、ヒートポンプ式の空気調和機の暖房運転では、暖房運転の指示を受けて圧縮機が起動し始め、温風が室内に吹き出すまでには時間がかかり、快適な温度になるまでには例えば３０分以上も要することがある。
【０００３】
しかも、暖房能力を最も必要とする運転開始直後の温風吹き出し温度は、十分な暖かさを与える温度ではない。
【０００４】
特に、外気温の低い寒冷地方あるいは準寒冷地方においては他の暖房器具と併用する必要があることが多く、ヒートポンプ式の空気調和機は本格的な暖房機としては認知され難かった。
【０００５】
このため、従来のヒートポンプ式の空気調和機には、暖房運転の運転開始直後から十分な暖かさを与える温風吹き出し温度の温風が出るまで時間を短くするように、蓄熱容器が設けられたものもあった。
【０００６】
【発明が解決しようとする課題】
蓄熱容器を設けた従来のヒートポンプ式の空気調和機では、蓄熱容器は、室外ユニットの本体下部に収納されており、圧縮機、四方弁、室外熱交換器、室外ファン等の冷凍サイクル機器の下部に位置していた。
【０００７】
このため、蓄熱容器のメインテナンスでは、蓄熱容器の上部に載置された圧縮機や四方弁等の冷凍サイクル機器を室外ユニットの外部へ一旦取り出し、蓄熱容器を外部に露出させた後に点検修理を行うようになっていた。
【０００８】
しかしながら、圧縮機や四方弁等の冷凍サイクル機器は蓄熱容器と冷媒配管によって強固に接続されており室外ユニットから圧縮機や四方弁等の冷凍サイクル機器を外すことはほぼ不可能であり、このため、蓄熱容器のメインテナンスが極めて困難であるという問題があった。
【０００９】
また、蓄熱容器が室外ユニットの本体下部に収納されているため蓄熱容器は設置地面の近くに位置し、このため、蓄熱容器が積雪や雨水に接したりして蓄熱容器の蓄熱特性を十分に発揮できないという問題があった。
【００１０】
また、従来のヒートポンプ式の空気調和機では、蓄熱容器が室外ユニットの本体下部に収納されているため、工場出荷から製品設置に至る製品搬送時等の種々の条件下で蓄熱容器を包囲する断熱材が蓄熱容器の上部に載置される冷凍サイクル機器によって圧縮されやすく、断熱材の断熱特性が劣化するという問題があった。
【００１１】
そこで、本発明の目的は上記従来技術の有する問題を解消し、蓄熱容器のメインテナンスが容易であり蓄熱容器の蓄熱特性を十分に発揮できる空気調和機を提供することである。
【００１２】
【課題を解決するための手段】
上記目的を達成するために、本願発明に係る空気調和機は、室外に設置される室外ユニットと室内に設置される室内ユニットとに分離し、圧縮機、四方弁、室内熱交換器、減圧装置、室外熱交換器を順次連通させて冷媒を循環させる冷凍サイクルを構成した冷暖可能な空気調和機において、前記室外ユニットの本体上部に、内部に蓄熱材が収容され内部を前記冷凍サイクルを循環する冷媒が通過し通過した冷媒を加熱させるための蓄熱容器を配設し、前記室外ユニットは、内部を前記本体上部と前記本体上部の下部にある本体下部とに区画するための蓄熱ベースと、前記本体下部を、前記室外熱交換器のための送風機が収納される送風機室と前記圧縮機が収納された機械室とに区画する仕切板と、を有し、前記蓄熱ベースに固定支持された前記蓄熱容器の荷重が前記蓄熱ベースを介して、前記送風機を駆動するモータを取り付けるモータベースへ負荷分担されるとともに前記仕切板または他の部品へ負荷分担されることを特徴とする。
【００１５】
また、本願発明に係る空気調和機は、室外に設置される室外ユニットと室内に設置される室内ユニットとに分離し、圧縮機、四方弁、室内熱交換器、減圧装置、室外熱交換器を順次連通させて冷媒を循環させる冷凍サイクルを構成した冷暖可能な空気調和機において、前記室外ユニットの本体上部に、内部に蓄熱材が収容され内部を前記冷凍サイクルを循環する冷媒が通過し通過した冷媒を加熱させるための蓄熱容器を配設し、前記室外ユニットは、内部を前記本体上部と前記本体上部の下部にある本体下部とに区画するための蓄熱ベースと、前記本体下部を、前記室外熱交換器のための送風機が収納される送風機室と前記圧縮機が収納された機械室とに区画する仕切板と、を有し、前記室外ユニットの内部には前記蓄熱容器に隣接して所定の電気機器が収納された電気箱が配設されており、前記蓄熱容器は前記電気箱に対し隙間をおいて配設されていることを特徴とする。
【００１６】
また、本願発明に係る空気調和機は、前記室外ユニットの内部には前記蓄熱容器の下方に電気機器が収納された電気箱が配設可能であり、前記電気箱は前記室外ユニットの前面側または側面側から着脱可能であることを特徴とする。
【００１７】
また、本願発明に係る空気調和機は、前記蓄熱容器は、その上面が前記室外ユニットの上部外壁を形成する上キャビネットの下面に隣接するように配設されていることを特徴とする。
【００１８】
また、本願発明に係る空気調和機は、前記蓄熱容器の外周面の全体を包囲する断熱部を備え、前記蓄熱容器は前記断熱部に包囲されて前記蓄熱ベースに固定可能であることを特徴とする。
【００１９】
また、本願発明に係る空気調和機は、前記蓄熱容器の荷重を受けるように前記断熱部の内壁に当接して配設される低熱伝導材で形成された内スペーサを備えていることを特徴とする。
【００２０】
また、本願発明に係る空気調和機は、搬送中に外力を受け圧縮可能な前記断熱部のその外壁部分に当接して配設されるスペーサを備えていることを特徴とする。
【００２１】
また、本願発明に係る空気調和機は、前記蓄熱容器の下方に前記蓄熱容器から漏れた蓄熱材を収容可能なドレイン皿を設けていることを特徴とする。
【００２２】
本願発明に係る空気調和機は、前記ドレイン皿に収容した蓄熱材を外部へ排出する排出口が形成され、この排出口が前記室外熱交換器の上方に位置することを特徴とする。
【００２３】
本願発明に係る空気調和機は、前記ドレイン皿に収容した蓄熱材を外部へ排出する排出口が形成され、この排出口の下方に回収タンクが配設され、前記排出口から排出される蓄熱材を前記回収タンクへ案内するホースを備えていることを特徴とする。
【００２４】
本願の第１３の発明に係る空気調和機は、第１０の発明において、前記ドレイン皿に収容した蓄熱材を外部へ排出する排出口が形成され、前記排出口から排出される蓄熱材を外部へ直接案内するホースを備えている。
【００２５】
本願発明に係る空気調和機は、前記ドレイン皿を前記蓄熱容器の底部一部部分の下方に設けていることを特徴とする。
【００２６】
本願発明に係る空気調和機は、前記蓄熱容器の外周面を包囲する断熱部を備え、前記ドレイン皿は前記断熱材と一体的に形成されていることを特徴とする。
【００２７】
本発明において、蓄熱容器を室外ユニットの本体上部に配設するようにしたので、電気箱の配設位置や圧縮機や室外送風機や室外熱交換器等の他の構成部品の配設位置に支障を生じさせることなく、蓄熱容器をこれらの他の部品と無理なく共存配置させることができ、蓄熱容器を外部に容易に露出させることができ、蓄熱容器のメインテナンスを容易に行うことができる。
【００２８】
蓄熱容器を室外ユニットの本体上部に配設するようにしたので、蓄熱容器を設置地面から離れて位置し、このため、蓄熱容器が積雪や雨水に接したりすることがなくなり、蓄熱容器の蓄熱特性を効率的に発揮することができる。
【００２９】
また、蓄熱容器を室外ユニットの本体上部に配設するようにしたので、工場出荷から製品設置に至る製品搬送時等の種々の条件下で蓄熱容器を包囲する断熱材が冷凍サイクル機器によって圧縮されることがなくなり、断熱材の断熱特性を有効に保持することができる。
【００３０】
また、蓄熱容器の下方にドレイン皿を設け蓄熱容器からなんらかの理由で漏れた蓄熱材を外部へ排出するようにしたので、他の構成部品の故障を誘発しないようにすることができる。
【００３１】
【発明の実施の形態】
以下に図面を参照して、本発明の実施形態を説明する。
【００３２】
図１４は本発明の実施形態に係る空気調和機の冷凍サイクル図である。この空気調和機は、室内ユニット４０と室外ユニット５０とからなり、冷媒を圧縮するロータリー圧縮機２に、四方弁３、室内送風機４を具備している室内熱交換器５、減圧装置である電子式膨張弁６、室外送風機８を具備している室外熱交換器９を冷媒配管１０により順次接続している。暖房運転においては、冷媒は矢印Ａの方向に冷媒配管１０内を循環する。
【００３３】
また、室外ユニット５０は蓄熱源１３を備えている。蓄熱源１３は、密閉した蓄熱容器１４と、蓄熱容器１４内に収容された不凍液からなる蓄熱材１６を加熱するためのヒータ等からなる加熱手段１７と、蓄熱容器１４内の圧力が所定圧力以上になったときにその圧力を解放するための圧力解放手段１８とを備えている。
【００３４】
室内熱交換器５と四方弁３とを結ぶ冷媒配管１０の部分と、室外熱交換器９と電子式膨張弁６とを結ぶ冷媒配管１０の部分との間には、冷媒配管１０を循環する冷媒の一部が流通可能な加熱冷媒供給配管１２が設けられている。加熱冷媒供給配管１２は蓄熱容器１４内を通過するように配設されている。
【００３５】
室内熱交換器５に近い加熱冷媒供給配管１２の部分には、冷媒が加熱冷媒供給配管１２中を流通することを開閉する二方弁２０が設けられている。冷媒配管１０から分岐した冷媒は、二方弁２０が開状態のときに、加熱冷媒供給配管１２内を矢印Ｂの方向に流れる。
【００３６】
蓄熱容器１４の外壁には温度センサ２２が配設され、温度センサ２２によって暖房運転の開始可能であるか否かが判断される。室外熱交換器９には室外熱交換器９に付着する霜の霜状態を検出する霜センサ２３が配設されている。センサ２２、２３の検出結果は制御部２４に送られる。制御部２４は、空気調和機の全体の制御を行う他に、センサ２２、２３による検出結果に応じて二方弁２０の開閉を行う。
【００３７】
図示しないリモコン等により暖房運転モ−ドあるいは除霜運転モードが選択操作されると、制御部２４により四方弁３がオン（通電）されると共に、温度センサー２２による検出温度が所定値以上であって蓄熱容器１４の熱容量が十分にあると判断され、また霜センサ２３により多量の霜があると判断されると、制御部２４により二方弁２０が開弁され、室内ファン４と室外ファン８が運転され、冷媒は冷凍サイクルを図中のＡ方向に循環する。
【００３８】
圧縮機２から吐出された高温高圧のガス冷媒が四方弁３により案内されて室内熱交換器５と加熱冷媒供給配管１２とに導入される。室内熱交換器５へ導入された冷媒はここで放熱して外気と熱交換して温風が室内ファン４により室内へ送風されて暖房を行ない、室内熱交換器５内で放熱する一方で凝縮して液化した液冷媒は電子式膨張弁６で減圧されてから室外熱交換器９内に流入し、ここで蒸発して液冷媒の蒸発潜熱により外気から吸熱してガス化し、室外ファン８の送風により、その熱交換が促進される。
【００３９】
一方、加熱冷媒供給配管１２に導入された冷媒は開弁されている二方弁２０を通り蓄熱容器１４内を通る際に蓄熱材１６により加熱されて気化し、高温のガス状冷媒として室外熱交換器９へ送られる。これによって、室外熱交換器９に多量の霜が付着しているときには霜が解除され、また、暖房運転モ−ドの開始直後にあっては迅速に暖房運転モードへ進行することができる。
【００４０】
次に、図１乃至図１３を参照して、室外ユニット５０に配設された蓄熱源１３について以下に詳細に説明する。
【００４１】
図１乃至図４に示すように、室外ユニット５０は上部外壁を形成する上キャビネット５１と、前部外壁を形成し一部にフィンガード５２ａの形成された前キャビネット５２と、後部外壁を形成する後キャビネット５３と、側部外壁を形成する側部キャビネット５４を有し、これらのキャビネットで囲われた略直方体の箱形状を有する。
【００４２】
室外ユニット５０の内部は、蓄熱ベース５５によって内部を蓄熱源１３が配設される蓄熱室６０が形成された本体上部と、本体上部の下方にある本体下部とに区画されている。本体下部は底部から立設された仕切板５６によって室外熱交換器９のための送風機８が収納される送風機室６１と圧縮機２等が収納された機械室６２とに区画されている。
【００４３】
図２または図４に示すように、送風機室６１には送風機８を駆動するモータ６４が取り付けられるモータベース６５が本体底部から立設されている。モータベース６５は、上部に平坦面が形成されるように上方で直角に折れた形状を有する。
【００４４】
本体下部の上方部には、インバータ電気器具等の所定の電気機器が収納された電気箱６６が配設されている。図４に示すように、電気箱６６は室外ユニット５０の前面側の前キャビネット５２をはずすことによって前面側から、あるいは側面側の側面キャビネット５４をはずすことによって側面側から容易に取り出すことができ、電気箱６６内の電気器具の故障修理等を容易に行うことができる。
【００４５】
蓄熱室６０に配設される蓄熱源１３は、蓄熱容器１４の外側が断熱材１５で包囲されて構成されている。
【００４６】
図４に示すように、蓄熱源１３はその両側で固定バンド５７によって蓄熱ベース５５上に固定されている。蓄熱ベース５５に固定された状態の蓄熱源１３は一体として、蓄熱ベース５５介して室外ユニット５０に装着される。
【００４７】
蓄熱ベース５５はその下面が、モータベース６５の上部平坦部に固着されている。また、蓄熱ベース５５は、仕切板５６の上端部と室外熱交換器９の上面にも支持されている。このようにして、蓄熱ベース５５に固定支持された蓄熱源１３の荷重は蓄熱ベース５５を介して、モータベース６５へ負荷分担されるとともに仕切板５６または室外熱交換器９等の他の部品へ負荷分担される。
【００４８】
図３に示すように、電気箱６６の上面と蓄熱ベース５５の下面との間には隙間５９が形成されている。これによって、蓄熱源１３の熱が電気箱６６に伝達することを防止している。
【００４９】
図１乃至図４に示すように、蓄熱源１３は、その上面が上キャビネット５１の下面にほぼ接触するように上キャビネット５１に隣接して配設されている。これによって、上キャビネット５１の上面から荷重がかかった場合に、その荷重を上キャビネット５１のみで直接的に受けることなく固定バンド５７や蓄熱ベース５５等を介して本体下部にあるモータベース６５等へ逃がし、受けた荷重によって上キャビネット５１が変形することが防止される。
【００５０】
次に、図５乃至図９を参照して、本発明の実施形態における断熱材１５について詳細に説明する。
【００５１】
図５は、蓄熱ベース５５に取り付けられる蓄熱源１３を示す組立分解斜視図である。蓄熱容器１４を包囲する断熱材１５は、蓄熱容器１４が収容される箱状断熱部１５ａと、蓄熱容器１４を収容した箱状断熱部１５ａに上方から蓋を被せるための蓋断熱部１５ｂとから構成されている。蓋断熱部１５ｂのには図８に示すように、圧力解放手段１８を外部に突出させるための孔が形成されている。
【００５２】
箱状断熱部１５ａと蓋断熱部１５ｂとによって外周全体を包囲された蓄熱容器１４は、箱状断熱部１５ａと蓋断熱部１５ｂの外側から固定バンド５７によって蓄熱ベース５５に固定される。
【００５３】
このように、蓄熱容器１４の外周全体を箱状断熱部１５ａと蓋断熱部１５ｂとで包囲することにより、蓄熱容器１４内の蓄熱材の保温性を維持することができる。
【００５４】
図６は、箱状断熱部１５ａの内側底面に蓄熱容器１４の荷重を受けるための円柱状の低熱伝導性の断熱材からなる内スペーサ１５ｃを２個配設した例を示す。内スペーサ１５ｃを設けない場合には、蓄熱容器１４の荷重を受ける箱状断熱部１５ａの底部部分が圧縮され、箱状断熱部１５ａの断熱特性が低下するおそれがあるが、内スペーサ１５ｃを設けることによって箱状断熱部１５ａに所定のの断熱特性を保持させることができる。
【００５５】
図７は、蓄熱ベース５５の四隅部に低熱伝導性の断熱材からなる４個のコーナスペーサ１５ｅを設けた例を示す。コーナスペーサ１５ｅには角柱状に抜かれた角柱凹部が形成されている。コーナスペーサ１５ｅは接着剤等によって蓄熱ベース５５の四隅部に取り付けられている。コーナスペーサ１５ｅの角柱凹部に蓄熱容器１４が収納される箱状断熱材１５ｄの底部四隅部がはめ込まれる。図９は、図７に示す４個のコーナスペーサ１５ｅを備えた室外ユニット５０の本体上部に蓄熱源１３が搭載された室外ユニット５０を示す斜視図である。図８は、図９に対応する組立分解斜視図である。
【００５６】
蓄熱源１３はコーナスペーサ１５ｅの角柱凹部にきつくはめ込むことが可能であるので、工場出荷から客先への室外ユニット５０の輸送中において、蓄熱源１３が前後左右に変位することを防止することができる。これによって、蓄熱源１３が前後左右に変位することによって生じ得る箱状断熱材１５ｄ等が圧縮されることを防止でき、箱状断熱部１５ｄ等に所定のの断熱特性を保持させることができる。
【００５７】
次に、図１０乃至図１３を参照して、本発明の実施形態におけるドレイン皿７０について詳細に説明する。
【００５８】
図１０は室外ユニット５０の本体上部に蓄熱源１３が搭載された室外ユニット５０を示す斜視図である。図１１は、図１０のＣ−Ｃにおける断面図である。図１１に示すように、内部に蓄熱容器１４が収容された断熱材１５の底部はドレイン皿７０に載置されて固定され、ドレイン皿７０は図示しない蓄熱ベース上に固定されている。このように、ドレイン皿７０は断熱材１５と一体的に形成されており、蓄熱容器尾１４と断熱材１５とドレイン皿７０とは一つのユニットとして図示しない蓄熱ベース上に取り付けられている。
【００５９】
図１１に示す例では、ドレイン皿７０はその下方にある電気箱６６や室外熱交換器９等の部品全体を保護するように断熱材１５の底部全体を覆うように設けられている。
【００６０】
断熱材１５の底部には漏れた蓄熱材を排出するための排出口７１が形成されている。また、ドレイン皿７０の底部には収容された蓄熱材を外部へ排出するための排出口７２が形成されている。ドレイン皿７０に形成された排出口７２は室外熱交換器９の上部に位置している。室外ユニット５０の底部には漏れた蓄熱材を回収するたの回収タンク７６が設けれている。排出口７２と回収タンク７６との間はホース７４によって連結されており、一旦ドレイン皿７０に収容された蓄熱材はホース７４によって回収タンク７６へ回収される。回収された蓄熱材は再利用に供することも可能である。
【００６１】
このように、ドレイン皿７０を設けることによって、蓄熱容器１４からなんらかの理由により漏れた蓄熱材をドレイン皿７０に一旦収容し、電気箱６６等の内部へ浸入することを防止し、確実に外部へ排出することができる。
【００６２】
なお、図１２に示すように、回収タンク７６を設けずホース７４によって漏れた蓄熱材を室外ユニットの外部へ直接排出することも可能である。

[0031]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
[0032]
FIG. 14 is a refrigeration cycle diagram of the air conditioner according to the embodiment of the present invention. This air conditioner includes an indoor unit 40 and an outdoor unit 50, and a rotary compressor 2 for compressing a refrigerant, an indoor heat exchanger 5 including a four-way valve 3 and an indoor blower 4, and an electronic device serving as a decompression device. An outdoor heat exchanger 9 having an expansion valve 6 and an outdoor blower 8 is sequentially connected by a refrigerant pipe 10. In the heating operation, the refrigerant circulates in the refrigerant pipe 10 in the direction of arrow A.
[0033]
The outdoor unit 50 includes the heat storage source 13. The heat storage source 13 includes a closed heat storage container 14, a heating unit 17 such as a heater for heating a heat storage material 16 made of antifreeze contained in the heat storage container 14, and a pressure in the heat storage container 14 which is equal to or higher than a predetermined pressure. And a pressure releasing means 18 for releasing the pressure when the pressure becomes zero.
[0034]
The refrigerant pipe 10 is circulated between a part of the refrigerant pipe 10 connecting the indoor heat exchanger 5 and the four-way valve 3 and a part of the refrigerant pipe 10 connecting the outdoor heat exchanger 9 and the electronic expansion valve 6. A heating refrigerant supply pipe 12 through which a part of the refrigerant can flow is provided. The heating refrigerant supply pipe 12 is disposed so as to pass through the heat storage container 14.
[0035]
A two-way valve 20 that opens and closes a refrigerant flowing through the heated refrigerant supply pipe 12 is provided at a portion of the heated refrigerant supply pipe 12 near the indoor heat exchanger 5. The refrigerant branched from the refrigerant pipe 10 flows in the heating refrigerant supply pipe 12 in the direction of arrow B when the two-way valve 20 is open.
[0036]
A temperature sensor 22 is provided on the outer wall of the heat storage container 14, and the temperature sensor 22 determines whether the heating operation can be started. The outdoor heat exchanger 9 is provided with a frost sensor 23 for detecting a frost state of frost adhering to the outdoor heat exchanger 9. The detection results of the sensors 22 and 23 are sent to the control unit 24. The control unit 24 opens and closes the two-way valve 20 according to the detection results of the sensors 22 and 23, in addition to controlling the entire air conditioner.
[0037]
When the heating operation mode or the defrosting operation mode is selected and operated by a remote controller (not shown) or the like, the four-way valve 3 is turned on (energized) by the control unit 24 and the temperature detected by the temperature sensor 22 is equal to or higher than a predetermined value. When it is determined that the heat capacity of the heat storage container 14 is sufficient and the frost sensor 23 determines that there is a large amount of frost, the two-way valve 20 is opened by the control unit 24, and the indoor fan 4 and the outdoor fan 8 are opened. Is operated, and the refrigerant circulates in the refrigeration cycle in the direction A in the figure.
[0038]
The high-temperature and high-pressure gas refrigerant discharged from the compressor 2 is guided by the four-way valve 3 and introduced into the indoor heat exchanger 5 and the heated refrigerant supply pipe 12. The refrigerant introduced into the indoor heat exchanger 5 radiates heat there and exchanges heat with the outside air, and the warm air is blown into the room by the indoor fan 4 to perform heating and condenses while radiating heat inside the indoor heat exchanger 5. The liquefied liquid refrigerant is decompressed by the electronic expansion valve 6 and then flows into the outdoor heat exchanger 9 where it evaporates and absorbs heat from the outside air due to the latent heat of vaporization of the liquid refrigerant to gasify it. The air exchange promotes the heat exchange.
[0039]
On the other hand, the refrigerant introduced into the heating refrigerant supply pipe 12 passes through the open two-way valve 20 and passes through the heat storage container 14, is heated and vaporized by the heat storage material 16, and becomes a high-temperature outdoor refrigerant as a high-temperature gaseous refrigerant. It is sent to the exchanger 9. Thus, when a large amount of frost is attached to the outdoor heat exchanger 9, the frost is released, and immediately after the start of the heating operation mode, it is possible to quickly proceed to the heating operation mode.
[0040]
Next, the heat storage source 13 provided in the outdoor unit 50 will be described in detail below with reference to FIGS.
[0041]
As shown in FIGS. 1 to 4, the outdoor unit 50 forms an upper cabinet 51 forming an upper outer wall, a front cabinet 52 forming a front outer wall and partially forming a fingered 52a, and a rear outer wall. It has a rear cabinet 53 and a side cabinet 54 forming a side outer wall, and has a substantially rectangular parallelepiped box shape surrounded by these cabinets.
[0042]
The interior of the outdoor unit 50 is partitioned by a heat storage base 55 into an upper body in which a heat storage chamber 60 in which the heat storage source 13 is disposed is formed, and a lower body below the upper body. The lower part of the main body is divided into a blower room 61 in which the blower 8 for the outdoor heat exchanger 9 is housed and a machine room 62 in which the compressor 2 and the like are housed by a partition plate 56 erected from the bottom.
[0043]
As shown in FIG. 2 or FIG. 4, a motor base 65 to which a motor 64 for driving the blower 8 is attached is provided upright from the bottom of the main body in the blower chamber 61. The motor base 65 has a shape that is bent upward at a right angle so that a flat surface is formed on the upper portion.
[0044]
An electric box 66 in which predetermined electric equipment such as an inverter electric appliance is stored is provided in an upper part of a lower part of the main body. As shown in FIG. 4, the electric box 66 can be easily removed from the front side by removing the front cabinet 52 on the front side of the outdoor unit 50, or from the side by removing the side cabinet 54 on the side. Failure repair or the like of the electric equipment in the electric box 66 can be easily performed.
[0045]
The heat storage source 13 provided in the heat storage chamber 60 is configured such that the outside of the heat storage container 14 is surrounded by a heat insulating material 15.
[0046]
As shown in FIG. 4, the heat storage source 13 is fixed on the heat storage base 55 by fixing bands 57 on both sides thereof. The heat storage source 13 fixed to the heat storage base 55 is integrally mounted on the outdoor unit 50 via the heat storage base 55.
[0047]
The lower surface of the heat storage base 55 is fixed to the upper flat portion of the motor base 65. The heat storage base 55 is also supported on the upper end of the partition plate 56 and the upper surface of the outdoor heat exchanger 9. In this way, the load of the heat storage source 13 fixed and supported by the heat storage base 55 is shared by the motor base 65 via the heat storage base 55 and is also transmitted to other parts such as the partition plate 56 or the outdoor heat exchanger 9. Load sharing.
[0048]
As shown in FIG. 3, a gap 59 is formed between the upper surface of the electric box 66 and the lower surface of the heat storage base 55. This prevents the heat of the heat storage source 13 from being transmitted to the electric box 66.
[0049]
As shown in FIGS. 1 to 4, the heat storage source 13 is disposed adjacent to the upper cabinet 51 such that the upper surface thereof substantially contacts the lower surface of the upper cabinet 51. Thus, when a load is applied from the upper surface of the upper cabinet 51, the load is not directly received only by the upper cabinet 51, but is applied to the motor base 65 and the like at the lower part of the main body via the fixed band 57, the heat storage base 55 and the like. The upper cabinet 51 is prevented from being deformed by the escape and the received load.
[0050]
Next, the heat insulating material 15 in the embodiment of the present invention will be described in detail with reference to FIGS.
[0051]
FIG. 5 is an exploded perspective view showing the heat storage source 13 attached to the heat storage base 55. The heat insulating material 15 surrounding the heat storage container 14 includes a box-shaped heat insulating portion 15a in which the heat storage container 14 is stored, and a lid heat insulating portion 15b for covering the box-shaped heat insulating portion 15a in which the heat storage container 14 is stored from above. It is configured. As shown in FIG. 8, a hole for projecting the pressure releasing means 18 to the outside is formed in the lid heat insulating portion 15b.
[0052]
The heat storage container 14 whose entire outer periphery is surrounded by the box-shaped heat-insulating portion 15a and the lid heat-insulating portion 15b is fixed to the heat storage base 55 by a fixing band 57 from outside the box-shaped heat-insulating portion 15a and the lid heat-insulating portion 15b.
[0053]
In this manner, by enclosing the entire outer periphery of the heat storage container 14 with the box-shaped heat insulating portion 15a and the lid heat insulating portion 15b, the heat retention of the heat storage material in the heat storage container 14 can be maintained.
[0054]
FIG. 6 shows an example in which two cylindrical inner spacers 15c made of a heat insulating material having low thermal conductivity for receiving the load of the heat storage container 14 are provided on the inner bottom surface of the box-shaped heat insulating portion 15a. If the inner spacer 15c is not provided, the bottom portion of the box-shaped heat-insulating portion 15a that receives the load of the heat storage container 14 may be compressed and the heat-insulating properties of the box-shaped heat-insulating portion 15a may be reduced. This allows the box-shaped heat-insulating portion 15a to maintain predetermined heat-insulating properties.
[0055]
FIG. 7 shows an example in which four corner spacers 15 e made of a heat insulating material having low thermal conductivity are provided at the four corners of the heat storage base 55. The corner spacer 15e is formed with a prismatic concave portion that is removed in a prismatic shape. The corner spacers 15e are attached to the four corners of the heat storage base 55 with an adhesive or the like. The four bottom corners of the box-shaped heat insulating material 15d in which the heat storage container 14 is stored are fitted in the prismatic concave portions of the corner spacers 15e. FIG. 9 is a perspective view showing the outdoor unit 50 in which the heat storage source 13 is mounted on the upper part of the main body of the outdoor unit 50 having the four corner spacers 15e shown in FIG. FIG. 8 is an exploded perspective view corresponding to FIG.
[0056]
Since the heat storage source 13 can be tightly fitted into the prismatic recess of the corner spacer 15e, it is possible to prevent the heat storage source 13 from being displaced from front to back and left and right during transportation of the outdoor unit 50 from factory shipment to the customer. it can. Thus, the box-shaped heat insulating material 15d and the like that may be generated by the heat storage source 13 being displaced in the front-rear and left-right directions can be prevented from being compressed, and the box-shaped heat-insulating portion 15d and the like can maintain predetermined heat-insulating properties.
[0057]
Next, the drain tray 70 in the embodiment of the present invention will be described in detail with reference to FIGS.
[0058]
FIG. 10 is a perspective view showing the outdoor unit 50 in which the heat storage source 13 is mounted on the main body of the outdoor unit 50. FIG. 11 is a cross-sectional view taken along line CC of FIG. As shown in FIG. 11, the bottom of the heat insulating material 15 in which the heat storage container 14 is accommodated is placed and fixed on a drain plate 70, and the drain plate 70 is fixed on a heat storage base (not shown). As described above, the drain dish 70 is formed integrally with the heat insulating material 15, and the heat storage container tail 14, the heat insulating material 15, and the drain dish 70 are mounted on a heat storage base (not shown) as one unit.
[0059]
In the example shown in FIG. 11, the drain plate 70 is provided so as to cover the entire bottom of the heat insulating material 15 so as to protect the entire components such as the electric box 66 and the outdoor heat exchanger 9 thereunder.
[0060]
A discharge port 71 for discharging the leaked heat storage material is formed at the bottom of the heat insulating material 15. An outlet 72 for discharging the stored heat storage material to the outside is formed at the bottom of the drain plate 70. An outlet 72 formed in the drain plate 70 is located above the outdoor heat exchanger 9. At the bottom of the outdoor unit 50, a recovery tank 76 for recovering the leaked heat storage material is provided. The outlet 72 and the recovery tank 76 are connected by a hose 74, and the heat storage material once stored in the drain plate 70 is recovered by the hose 74 into the recovery tank 76. The recovered heat storage material can be reused.
[0061]
As described above, by providing the drain plate 70, the heat storage material leaked from the heat storage container 14 for some reason is temporarily stored in the drain plate 70, and is prevented from entering the inside of the electric box 66 or the like, and is reliably discharged to the outside. Can be discharged.
[0062]
As shown in FIG. 12, the heat storage material leaked by the hose 74 can be directly discharged to the outside of the outdoor unit without providing the recovery tank 76.
[0063]
Also, without providing the hose 74, the heat storage material once stored in the drain plate 70 is discharged to the outside from the discharge port 72 located at the upper part of the outdoor heat exchanger 9 through the outer wall of the outdoor heat exchanger 9. Is also possible.
[0064]
In addition, as shown in FIG. 13, the drain plate 70 may be provided only on the upper part of the electric box 66 on the bottom of the heat insulating material 15. In this case, the leaked heat storage material is discharged to the outside from the discharge port 71 or the left end of the drain plate 70 via the wall of the outdoor heat exchanger 9. This makes it possible to reduce the size of the drain pan 70 and to surely protect the electric box 66, from which the leaked heat storage material is most likely to enter, from the leaked heat storage material.
[0065]
As described above, according to the embodiment of the present invention, the heat storage source 13 including the heat storage container 14 is disposed above the main body of the outdoor unit 50. The heat storage source 13 can be coexistently arranged with these other components without causing any trouble in the arrangement position of other components such as the outdoor blower 8, the outdoor blower 8, and the outdoor heat exchanger 9. The outdoor unit 50 can be made compact. Then, the heat storage container 14 can be easily exposed to the outside, and maintenance of the heat storage source 13 such as the heat storage container 14 can be easily performed.
[0066]
Further, since the heat storage source 13 is arranged above the main body of the outdoor unit 50, the heat storage source 13 can be located away from the installation ground, and the heat storage source 13 does not come into contact with snow or rainwater. In addition, the heat storage characteristics of the heat storage source 13 can be efficiently exhibited.
[0067]
In addition, since the heat storage source 3 is disposed above the main body of the outdoor unit 50, the heat insulating material 15 surrounding the heat storage container 14 under various conditions such as when the product is transported from factory shipment to product installation is a compressor. No compression is performed by the refrigeration cycle equipment such as 2 and the heat insulating property of the heat insulating material 15 can be effectively maintained.
[0068]
Moreover, since the heat storage container 14 is surrounded by the heat insulating material 15, the heat storage characteristics of the heat storage container 14 can be effectively maintained. In addition, by providing the spacers 15c and 15e made of a heat insulating material together with the heat insulating materials 15a and 15b, the heat insulating material 15 is compressed under various conditions such as during product transport from factory shipment to product installation, and the heat insulating property is deteriorated. Can be avoided.
[0069]
In addition, since the drain plate 70 is provided below the heat storage source 13 and the heat storage material leaked from the heat storage container 14 for some reason is discharged to the outside, failure of other components such as the electric box 66 is prevented. The heat storage source 13 can be safely and reliably operated, and the air conditioner can be safely and reliably operated.
[0070]
In this manner, the air conditioner including the heat storage source 13 can be safely and reliably operated. Therefore, even in a cold region or a quasi-cold region where the outside air temperature is low, a heat pump-type air conditioner can be used without using other heating appliances. The air conditioner can be used as a full-fledged heater.
[0071]
In the above description, the air conditioner provided with the refrigeration cycle shown in FIG. 14 has been described as an example of the air conditioner. However, the refrigeration cycle is not limited to that shown in FIG. Any other refrigeration cycle may be used.
[0072]
