In order to penetrate the plate, an inverted U-shaped notch was formed in the partition plate (see, for example, Patent Document 2).
図６は、特許文献１に記載された従来のヒートポンプユニットの内部斜視図を示すものである。図６に示すように、ヒートポンプユニット１０１は、基板１０２上の右側には、圧縮機１０３や図示されていないが、膨張弁を介した冷媒循環配管および貯湯タンクユニットと接続される水循環配管が構成され、一方、基板上の左側には、基板１０２の後方に、略Ｌ字状に曲げて形成された空気冷媒熱交換器１０４が配され、その前方には、水冷媒熱交換器１０５が配されている。 FIG. 6 shows an internal perspective view of a conventional heat pump unit described in Patent Document 1.

１０６は、水冷媒熱交換器１０５を覆うように設けられた断熱部材であり、１０７は、断熱部材１０６を上から周囲を覆うように設けられた保護カバーである。１０８は、空気冷媒熱交換器１０４の熱交換能力を高めるための送風ファンであり、空気冷媒熱交換器１０４の前方、保護カバー１０７の上方に配されている。 106 is a heat insulating member provided so as to cover the water-refrigerant heat exchanger 105, and 107 is a protective cover provided so as to cover the heat insulating member 106 from above. Reference numeral 108 denotes a blower fan for increasing the heat exchange capability of the air refrigerant heat exchanger 104, and is arranged in front of the air refrigerant heat exchanger 104 and above the protective cover 107.
１０９は、圧縮機１０３のある空間と、空気冷媒熱交換器１０４や水冷媒熱交換器１０５とを区画する仕切板である。そして、仕切板１０９には、爪部１０９ａが設けられており、その爪部１０９ａと、保護カバー１０７のＵ字カット部１０７ａが係合することで、保護カバー１０７の位置決めがなされている。 Reference numeral 109 denotes a partition plate that partitions the space where the compressor 103 is located from the air refrigerant heat exchanger 104 and the water refrigerant heat exchanger 105. The partition plate 109 is provided with a claw portion 109a, and the claw portion 109a and the U-shaped cut portion 107a of the protective cover 107 are engaged to position the protective cover 107.
また、図７は、特許文献２に記載された従来のヒートポンプユニットの内部部品構成を示すものである。図７に示すように、ヒートポンプユニット１０１の基板１０２上には、圧縮機１０３や水冷媒熱交換器１０５などを配設し、それらの間には防音板を兼ねて仕切る仕切板１０９が配設され、その上部には、このヒートポンプユニットを制御する電源制御箱１１０が配置されている。 FIG. 7 shows an internal component configuration of a conventional heat pump unit described in Patent Document 2. As shown in FIG. 7, a compressor 103, a water-refrigerant heat exchanger 105, and the like are disposed on the substrate 102 of the heat pump unit 101, and a partition plate 109 that also serves as a soundproof plate is disposed between them. A power control box 110 for controlling the heat pump unit is disposed at the top.
仕切板１０９の前方下部には、逆Ｕ字形の切り欠き部１０９ｂが形成され、仕切板１０９は、圧縮機１０３と水冷媒熱交換器１０５の間で上方より基板１０２に挿し降ろして固定させ、水冷媒熱交換器１０５と、筐体の前方で連通した圧縮機１０３や空気冷媒熱交換器１０４と環状に接続した冷媒循環配管および貯湯タンクユニットと接続される水循環配管の管路１１１が貫通される構成となっている。 An inverted U-shaped notch 109b is formed in the lower front portion of the partition plate 109. The partition plate 109 is inserted and fixed to the substrate 102 from above between the compressor 103 and the water-refrigerant heat exchanger 105, and fixed. Pipe line 111 of water circulation pipe connected to water refrigerant heat exchanger 105 and refrigerant circulation pipe and hot water storage tank unit connected annularly to compressor 103 and air refrigerant heat exchanger 104 communicated in front of the casing. It is the composition which becomes.
以上の構成により、ヒートポンプユニット１０１の運転時における防音性能の向上を図り、ヒートポンプユニット１０１の輸送時に加わる外力に対する強度を増し、組立時の水冷媒熱交換器１０５の位置決めが明確になり作業性の向上が図れるといわれている。 With the above configuration, the soundproof performance during the operation of the heat pump unit 101 is improved, the strength against the external force applied during the transportation of the heat pump unit 101 is increased, and the positioning of the water-refrigerant heat exchanger 105 at the time of assembly becomes clear and the workability is improved. It is said that improvement can be achieved.
しかしながら、前記従来の構成では、水冷媒熱交換器に不具合が発生してサービスメンテナンス交換作業する場合、冷媒循環配管および水循環配管の管路１１１が仕切板１０９の切り欠き部１０９ｂに囲われ、また保護カバー１０７のＵ字カット部１０７ａに対して、仕切板の爪部１０９ａが上方より挿し降ろされて係合されているため、本体の上部に配置された送風ファン部１０８、電源制御箱１１０、仕切板１０９を順に取り外した後に、保護カバー１０７や水冷媒熱交換器１０５を取り外さなければならず、大変に作業工数がかかるという課題があった。 However, in the conventional configuration, when a service maintenance replacement work is performed due to a failure in the water refrigerant heat exchanger, the refrigerant circulation pipe and the water circulation pipe 111 are surrounded by the notch 109b of the partition plate 109, and Since the claw portion 109a of the partition plate is inserted and lowered from above with respect to the U-shaped cut portion 107a of the protective cover 107, the blower fan portion 108, the power control box 110, After removing the partition plate 109 in order, the protective cover 107 and the water-refrigerant heat exchanger 105 have to be removed, and there is a problem that it takes a lot of work.

(Embodiment 1)
FIG. 1 is a front internal configuration diagram of a heat pump unit according to the first embodiment of the present invention. 2 is a partition plate diagram, FIG. 3 is a detailed perspective view, and FIG. 4 is an exploded configuration diagram.
図１において、ヒートポンプユニットの底面を支持する基板１の上部には、仕切板２によって区画した一方に圧縮機３を搭載し、もう一方の区画には仕切板２に隣接して水冷媒
熱交換器４が載置されている。圧縮機３は、水冷媒熱交換器４、減圧手段、空気冷媒熱交換器５を順次接続した冷媒循環配管６が接続され、筐体の右側面部には、貯湯タンクユニットと接続される水循環配管７の接続部８が設けられている。
In FIG. 1, a compressor 3 is mounted on one side partitioned by a partition plate 2 on the upper portion of a substrate 1 that supports the bottom surface of the heat pump unit, and water refrigerant heat exchange is performed adjacent to the partition plate 2 in the other partition. A vessel 4 is placed. The compressor 3 is connected to a refrigerant circulation pipe 6 in which a water refrigerant heat exchanger 4, a decompression unit, and an air refrigerant heat exchanger 5 are sequentially connected, and a water circulation pipe connected to a hot water storage tank unit on the right side surface of the housing. 7 connecting portions 8 are provided.
図３に示すように、水循環配管７は、圧縮機３の前方部および仕切板２の切り欠き部２ａ内で、冷媒循環配管６と合体した管路９となり、水冷媒熱交換器４に連通して構成されている。 As shown in FIG. 3, the water circulation pipe 7 becomes a pipe 9 combined with the refrigerant circulation pipe 6 in the front part of the compressor 3 and the notch 2 a of the partition plate 2, and communicates with the water refrigerant heat exchanger 4. Configured.
仕切板２は、図２に示すように、前方下部は、前方側に開口した開口部である切り欠き形状２ａが形成されている。また、仕切板２の上部には、製品の運転を制御する電源制御箱１０が載置されている。 As shown in FIG. 2, the partition plate 2 has a notch shape 2 a that is an opening that opens to the front side at the front lower portion. A power control box 10 for controlling the operation of the product is placed on the upper part of the partition plate 2.
水冷媒熱交換器４は、上下に２分割された発泡断熱容器１１に収納され、その外郭は保護カバー１２に覆われている。保護カバー１２の上部には、送風ファン１３が搭載され、その後方には、空気冷媒熱交換器４が載置されている。 The water-refrigerant heat exchanger 4 is housed in a foam insulation container 11 that is divided into two parts in the vertical direction, and its outer shell is covered with a protective cover 12. A blower fan 13 is mounted on the upper portion of the protective cover 12, and an air refrigerant heat exchanger 4 is placed behind the blower fan 13.
以上のように構成されたヒートポンプユニットについて、以下その動作、作用を説明する。 About the heat pump unit comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
ヒートポンプ給湯機のヒートポンプユニットを長期に運転し続けると、水分中の炭酸カルシウム成分などが加熱によりスケールという固形物となって、水冷媒熱交換器４の水循環配管７内に析出して、配管内を閉塞させ、水が循環不能となり、運転不良となる。そのような場合、サービスメンテナンスで水冷媒熱交換器４の交換が必要となる場合がある。 If the heat pump unit of the heat pump water heater is continuously operated for a long period of time, the calcium carbonate component in the water becomes a solid matter called scale due to heating and precipitates in the water circulation pipe 7 of the water refrigerant heat exchanger 4, The water cannot be circulated, resulting in poor operation. In such a case, it may be necessary to replace the water refrigerant heat exchanger 4 in service maintenance.
上記構成によって、水冷媒熱交換器４を取り外す場合、まず送風ファン部１３を取り外し一方、圧縮機３の前方部などで水循環配管７および冷媒循環配管６のロー付け箇所を外す。 When removing the water-refrigerant heat exchanger 4 with the above configuration, first, the blower fan portion 13 is removed, and the brazed portions of the water circulation pipe 7 and the refrigerant circulation pipe 6 are removed at the front portion of the compressor 3 or the like.
この結果、水冷媒熱交換器４は、水および冷媒循環回路より切り離されて、単品化したことになる。水循環配管７および冷媒循環配管６の合体した管路９は、仕切板２の前方に開口された切り欠き部２ａに貫通されて配置されているので、図４に示すように、水冷媒熱交換器４は、保護カバー１２と発泡断熱容器１１に収納され一体となったまま、または保護カバー１２と上側の発泡断熱容器１１を外した後、前方に引き出して取り外すことができ、サービスメンテナンス性の向上が図られる。 As a result, the water / refrigerant heat exchanger 4 is separated from the water / refrigerant circuit and is made into a single product. The pipe 9 combined with the water circulation pipe 7 and the refrigerant circulation pipe 6 is disposed so as to penetrate through the notch 2a opened in front of the partition plate 2. Therefore, as shown in FIG. The container 4 can be removed by pulling forward while being housed in the protective cover 12 and the foam insulation container 11 as a unit, or after the protection cover 12 and the upper foam insulation container 11 are removed. Improvement is achieved.
また、図５において、水冷媒熱交換器４を収納した発泡断熱容器１１を覆う保護カバー１２に仕切板２と接触する折り曲げ面を形成し、さらに正面側に平面部となるＬ字形状の連結部１２ａを設けたものである。 In FIG. 5, a bent surface that contacts the partition plate 2 is formed on the protective cover 12 that covers the foam insulation container 11 that houses the water-refrigerant heat exchanger 4, and an L-shaped connection that forms a flat portion on the front side. A portion 12a is provided.
さらに仕切板２には前方より開口となる切り欠き部２ａの上部に段差部２ｂを設け、前記保護カバー１２の連結部１２ａと仕切板２の切り欠き部２ａの上部段差部２ｂはねじ締結などで連結係合されている。 Further, the partition plate 2 is provided with a step 2b at the top of the notch 2a that is open from the front, and the connecting step 12a of the protective cover 12 and the upper step 2b of the notch 2a of the partition 2 are screwed or the like. Are connected and engaged.
水冷媒熱交換器４を収納した発泡断熱容器１１を覆う保護カバー１２は、保護カバー１２の連結部１２ａを仕切板段差部２ｂに係合固定することにより、組立時に位置ずれし易い水冷媒熱交換器４の位置決めが明確になり、作業性の向上が図れる。 The protective cover 12 that covers the foam insulation container 11 that houses the water-refrigerant heat exchanger 4 engages and fixes the connecting portion 12a of the protective cover 12 to the partition plate stepped portion 2b, so that the water-refrigerant heat that is easily displaced during assembly is obtained. The positioning of the exchanger 4 becomes clear and workability can be improved.
また、ヒートポンプユニットの運転時に、送風ファン１３や水冷媒熱交換器４から振動が伝播されるが、係合により、その振動を緩和させ、製品の防音性能の向上を図ることができる。また、製品輸送時に、重量物である水冷媒熱交換器４は外力により、移動し易い
が、係合固定により強度を増し、製品の破損防止や異常音防止を図ることができる。
Further, vibration is propagated from the blower fan 13 and the water / refrigerant heat exchanger 4 during operation of the heat pump unit. By engagement, the vibration can be mitigated and the soundproof performance of the product can be improved. In addition, the water-refrigerant heat exchanger 4 that is a heavy object is easily moved by an external force during product transportation, but the strength is increased by engagement and fixation, so that the product can be prevented from being damaged or abnormal noise.
また、図５において、水冷媒熱交換器４を収納した発泡断熱容器１１を覆う保護カバー１２の連結部１２ａは、前方より切り欠き部２ａを設けた仕切板２に形成された段差部２ｂに係合され、前記段差部２ｂの上部には傾斜部２ｃが配設されている。 Further, in FIG. 5, the connecting portion 12 a of the protective cover 12 covering the foam heat insulating container 11 in which the water-refrigerant heat exchanger 4 is housed is a step portion 2 b formed on the partition plate 2 provided with the notch portion 2 a from the front. The inclined portion 2c is disposed above the stepped portion 2b.
保護カバー１２の連結部１２ａは、仕切板２に形成された段差部２ｂの深さ内に収納されて、筐体の外箱前板１４に対して、凸形状となることなく、製品の外観デザインの向上が図られる。 The connecting portion 12a of the protective cover 12 is housed within the depth of the stepped portion 2b formed in the partition plate 2, and does not have a convex shape with respect to the outer box front plate 14 of the housing, and the appearance of the product. The design is improved.
また、サービスメンテナンス時に、水冷媒熱交換器４を収納した発泡断熱容器１１を覆う保護カバー１２を上方に取り外そうとする場合、保護カバー１２の連結部１２ａは、仕切板２に形成された段差部２ｂの上部傾斜部２ｃに沿って摺動するため、引っかかることなく、容易に取り外すことができ、サービスメンテナンス性の向上が図られる。 Further, when service protection is to be performed, when the protective cover 12 covering the foam heat insulating container 11 containing the water-refrigerant heat exchanger 4 is to be removed upward, the connecting portion 12a of the protective cover 12 is formed on the partition plate 2. Since it slides along the upper inclined part 2c of the step part 2b, it can be easily removed without being caught, and service maintenance is improved.
また、図５において、水冷媒熱交換器４を収納した発泡断熱容器１１を覆う保護カバー１２の前方下部１２ｂは、筐体の基板２の周囲縁より前方に配設されている。図４のように、筐体の外箱前板１４は、前方より、基板１の周囲縁に合わされ、前方よりねじ締め付けされ、固定される。 Further, in FIG. 5, the front lower portion 12 b of the protective cover 12 covering the foam insulation container 11 in which the water-refrigerant heat exchanger 4 is housed is disposed in front of the peripheral edge of the substrate 2 of the housing. As shown in FIG. 4, the outer box front plate 14 of the housing is fitted to the peripheral edge of the substrate 1 from the front, and is screwed and fixed from the front.
保護カバー１２の前方下部１２ｂは、外箱前板１４と基板１に挟んで係合されることになり、運転時の水冷媒熱交換器４の振動や送風ファン１３の振動が保護カバー１２に伝播しても、基板１と外箱前板１４によって振動が緩和され、製品本体の防音性能を向上させることができる。 The front lower portion 12b of the protective cover 12 is engaged with the outer casing front plate 14 and the substrate 1 so that the vibration of the water / refrigerant heat exchanger 4 and the vibration of the blower fan 13 during operation are applied to the protective cover 12. Even if it propagates, the vibration is mitigated by the substrate 1 and the outer case front plate 14, and the soundproofing performance of the product body can be improved.
以上のように、本発明にかかるヒートポンプ給湯機のヒートポンプユニットは、容易に水冷媒熱交換器が取り外し可能となり、サービスメンテナンス性の向上及び、防音性能の向上が可能となるので、給湯機や空調機等の用途にも適用できる。 As described above, in the heat pump unit of the heat pump water heater according to the present invention, the water-refrigerant heat exchanger can be easily removed, and service maintenance can be improved and soundproof performance can be improved. It can also be used for machine applications.
