本発明はヒートポンプ式熱源機に関し、特に制御装置のメンテナンス性の向上を図ったヒートポンプ式熱源機に関する。 The present invention relates to a heat pump heat source machine, and more particularly to a heat pump heat source machine that improves the maintainability of a control device.
従来、貯湯式給湯装置として、貯湯式のヒートポンプ式給湯装置が実用に供されている。この給湯装置は、温水を貯留する大容量の貯湯タンクと、ケース体に収容されたヒートポンプ回路を有するヒートポンプ式熱源機とを備え、夜間割引の安価な電力を利用して、貯湯タンク内の湯水を循環させてヒートポンプ式熱源機で加熱して、その加熱された湯水を貯湯タンクに貯留しておき、蛇口や風呂などの所望の給湯先に給湯するものである。 Conventionally, a hot water storage type heat pump type hot water supply apparatus has been put to practical use as a hot water storage type hot water supply apparatus. This hot water supply device includes a large-capacity hot water storage tank for storing hot water and a heat pump type heat source device having a heat pump circuit housed in a case body, and uses hot power at a night discount to provide hot water in the hot water storage tank. Is circulated and heated by a heat pump type heat source device, and the heated hot water is stored in a hot water storage tank and supplied to a desired hot water supply destination such as a faucet or a bath.
上記のヒートポンプ式熱源機のヒートポンプ回路において、圧縮機、凝縮器、膨張弁、蒸発器が冷媒配管を介して接続され、冷媒配管に封入された冷媒を利用して給湯加熱運転が行われる。給湯加熱運転では、蒸発器に外気を導入する送風機が駆動されて外気から冷媒に吸熱し、凝縮器により冷媒と湯水との間で熱交換が行われて湯水が加熱される。 In the heat pump circuit of the heat pump heat source apparatus, a compressor, a condenser, an expansion valve, and an evaporator are connected via a refrigerant pipe, and a hot water supply heating operation is performed using the refrigerant sealed in the refrigerant pipe. In the hot water supply heating operation, a blower that introduces outside air to the evaporator is driven to absorb heat from the outside air to the refrigerant, and heat is exchanged between the refrigerant and hot water by the condenser to heat the hot water.
ところで、上記の各種機器の動作制御を実行する制御装置もケース体内に収容されている。この種の制御装置は、一般に、箱状のケース部材と、このケース部材に収容され且つ複数の電子部品が実装された制御基板と、各種電子部品からの放熱を外部に放出する為の放熱器等を備えている。放熱器は、ケース部材の開口部を通って外部に露出している。制御装置がケース体内に配置された構造としては、特許文献１，２のような構造が実用に供されている。 By the way, a control device that performs operation control of the various devices is also housed in the case body. This type of control device generally includes a box-shaped case member, a control board accommodated in the case member and mounted with a plurality of electronic components, and a radiator for releasing heat radiation from various electronic components to the outside. Etc. The radiator is exposed to the outside through the opening of the case member. As a structure in which the control device is arranged in the case body, structures such as Patent Documents 1 and 2 are practically used.
例えば、特許文献１のヒートポンプ装置は、各種機器を収容した外装体を備え、この外装体の内部を仕切り板によって送風ファンと空気熱交換器（蒸発器）とを配置した送風室と圧縮機と水冷媒熱交換器（凝縮器）とを配置した機械室とに区画され、制御基板を収容した電装箱の大部分を送風室の上部に配置した構造が記載されている。電装箱の送風室側部分は、外装体の底板から垂直に延び且つ上端部が水平方向に延びる支持金具の上端部に載置され、電装箱の機械室側端部は、仕切り板の上端部に載置されている。 For example, the heat pump device of Patent Document 1 includes an exterior body that accommodates various devices, and a blower chamber and a compressor in which a blower fan and an air heat exchanger (evaporator) are arranged by a partition plate inside the exterior body. A structure is described in which most of the electrical box that is partitioned into a machine room in which a water-refrigerant heat exchanger (condenser) is arranged and accommodates a control board is arranged in the upper part of the blower chamber. The air blower chamber side portion of the electrical box is placed on the upper end of the support bracket that extends vertically from the bottom plate of the exterior body and the upper end extends in the horizontal direction, and the machine chamber side end of the electrical box is the upper end of the partition plate. Is placed.
一般に、特許文献１のように仕切り板を備えた構造では、ケース体内に制御装置を配置する場合、ケース体の天板を取り付ける前に、水平姿勢の制御装置をケース体内に上方から挿入し、支持金具と仕切り板の上端部に載置して固定する構造が採用される。天板は、制御装置を取り付けた後にケース体に取り付けられる。 In general, in the structure having a partition plate as in Patent Document 1, when the control device is arranged in the case body, the horizontal posture control device is inserted into the case body from above before attaching the top plate of the case body, A structure that is placed and fixed on the upper end portions of the support fitting and the partition plate is employed. The top plate is attached to the case body after the control device is attached.
ヒートポンプ式給湯装置を長期間使用していると、制御装置が故障する場合がある。そのため、修理やメンテナンスを行う必要がある。制御装置の制御基板には、多種多様な精密な電子部品が実装されているので、電子部品単位の修理は難しく、故障時には制御装置ごと交換するのが一般的である。 If the heat pump hot water supply device is used for a long time, the control device may break down. Therefore, it is necessary to perform repair and maintenance. Since a wide variety of precision electronic components are mounted on the control board of the control device, it is difficult to repair each electronic component, and it is common to replace the control device when a failure occurs.
しかし、特許文献１の仕切り板のある構造では、制御装置を交換する為には、ケース体から天板を取り外して、ケース体を上方に開放した状態にし、制御装置を固定しているビス締結を解除してから、制御装置を上方に取り出さなければならず、制御装置を取り外しにくく、修理やメンテナンスに多くの時間とコストがかかる。 However, in the structure with the partition plate of Patent Document 1, in order to replace the control device, the top plate is removed from the case body, the case body is opened upward, and the screw fastening is fixed to the control device. After the control is released, the control device must be taken out upward, it is difficult to remove the control device, and much time and cost are required for repair and maintenance.
また、制御装置を上方へ取り出す代わりにケース体の前方へ取り出す構造を採用することも考えられるが、この場合制御装置が仕切り板と干渉する虞があり、制御装置を簡単に着脱可能な構造とはなっていない。従って、上記の特許文献１の装置と同様に、作業が複雑となり、修理やメンテナンスに困難が伴う。 It is also conceivable to adopt a structure in which the control device is taken out in front of the case body instead of taking out the control device. In this case, the control device may interfere with the partition plate, and the control device can be easily attached and detached. It is not. Therefore, like the apparatus of the above-mentioned Patent Document 1, the work becomes complicated, and repair and maintenance are difficult.

補助制御装置２４の上側ケース５７と下側ケース５８の後壁部には、その後壁部に一体形成されたシール溝形成部材６７により浅い角溝状のシール溝６８が形成され、そのシール溝６８にシール部材６９が装着されている。尚、この溝形成部材６７とシール部材６９は、上側ケース５７と下側ケース５８の境界部において分割されている。このシール部材６９は後側板部４７に圧接状に当接して、上下のケース５７，５８と後側板部４７の間を気密にシールしている。 A shallow groove-like seal groove 68 is formed on the rear wall portions of the upper case 57 and the lower case 58 of the auxiliary control device 24 by a seal groove forming member 67 integrally formed on the rear wall portion. A seal member 69 is attached to the head. The groove forming member 67 and the seal member 69 are divided at the boundary between the upper case 57 and the lower case 58. The seal member 69 abuts against the rear plate portion 47 in a pressure-contact manner, and hermetically seals between the upper and lower cases 57 and 58 and the rear plate portion 47.
このように、上記のシール構造により、補助制御装置２４と仕切り板４５との間と、補助制御装置２４と天板４０との間を気密に封止するので、送風室４２内を流れる外気が機械室４３側に流入するのを防止することができ、機械室４３に雨水や埃が流入するのを防止することができる。 As described above, since the seal structure described above seals the space between the auxiliary control device 24 and the partition plate 45 and between the auxiliary control device 24 and the top plate 40, the outside air flowing in the blower chamber 42 is prevented. Inflow to the machine room 43 side can be prevented, and rainwater and dust can be prevented from flowing into the machine room 43.
尚、上記のシール部材６３，６６，６９は、独立気泡の発泡体で構成されるが、特にこれに限定する必要はなく、他の素材からなるシール部材も適用可能である。また、上下のケース５７，５８の前面のリブにシール部材を被せて封止してもよい。 The above-described seal members 63, 66, and 69 are formed of closed-cell foams, but are not particularly limited to this, and seal members made of other materials are also applicable. Further, sealing may be performed by covering the ribs on the front surfaces of the upper and lower cases 57 and 58 with a sealing member.
次に、本発明のヒートポンプ式熱源機３の作用、効果について説明する。
先ず、外装ケース２５の前側板３７を取り外した状態で、ヒートポンプ式熱源機３の外装ケース２５内に補助制御装置２４を装着する場合、水平姿勢の補助制御装置２４を外装ケース２５の前方に保持し、補助制御装置２４のレール溝６２を、仕切り板４５のＬ字状受部４６ｆに対向させ、補助制御装置２４の左端部の嵌合部５８ｂを、受止部材５０の第１受止部５１の支持板５１ｃに載置可能に対向させ、補助制御装置２４を水平に後方移動させてＬ字状受部４６ｆに対してレール溝６２をスライドさせると共に、支持板５１ｃに対して左端部の嵌合部５８ｂをスライドさせて、補助制御装置２４の後端を第２受止部５２に当接させる。更に、補助制御装置２４を前側板部４６の上端部にビス６１ｅで締結することで固定し且つリード線のコネクタを接続する。
