Description
本発明は、ヒートポンプを熱源とする給湯機のヒートポンプユニットの構造に関するものである。 The present invention relates to a structure of a heat pump unit of a water heater using a heat pump as a heat source.
従来、この種のヒートポンプユニットは、圧縮機、水冷媒熱交換器、減圧手段および空気冷媒熱交換器を環状に接続し、空気を空気冷媒熱交換器に搬送する送風手段である送風ファンを空気冷媒熱交換器下流側に備え、この送風ファンを固定する送風ファン固定具と、送風ファン固定具下方で、空気冷媒熱交換器下方に水冷媒熱交換器を覆う保護カバーを設けており、空気冷媒熱交換器は複数の列のフィンチューブ熱交換器の場合、内側列のフィンチューブ熱交換器の下方部を、外側列のフィンチューブ熱交換器よりも所定長さ短くしている。 Conventionally, this type of heat pump unit connects a compressor, a water refrigerant heat exchanger, a decompression means, and an air refrigerant heat exchanger in an annular shape, and air blowing fans that are air blowing means for conveying air to the air refrigerant heat exchanger. Provided on the downstream side of the refrigerant heat exchanger, a blower fan fixture that fixes the blower fan, and a protective cover that covers the water refrigerant heat exchanger below the air refrigerant heat exchanger is provided below the blower fan fixture, In the case where the refrigerant heat exchanger is a plurality of rows of fin tube heat exchangers, the lower portion of the inner row fin tube heat exchanger is made shorter than the outer row fin tube heat exchanger by a predetermined length.
また、水冷媒熱交換器を覆う保護カバー上部にファンモーター固定具を固定する係止具を形成して空気冷媒熱交換器の内側列熱交換フィンと外側列熱交換器フィンを受け、筐体の基板背面端板に渉って一体形成した連結桟で連結固定することで機器自体の強度が向上されている（例えば、特許文献１参照）。 In addition, a locking member for fixing the fan motor fixing member is formed on the upper part of the protective cover that covers the water refrigerant heat exchanger to receive the inner row heat exchange fin and the outer row heat exchanger fin of the air refrigerant heat exchanger, and the housing The strength of the device itself is improved by connecting and fixing it with a connecting bar integrally formed behind the substrate back end plate (see, for example, Patent Document 1).
図７、図８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を示すものであり、図７は正面内観図、図８は左断面図を示すものである。 7 and 8 show a conventional heat pump unit described in Patent Document 1, FIG. 7 shows a front interior view, and FIG. 8 shows a left sectional view.
図７に示すように、水冷媒熱交換器を備えたヒートポンプユニット１０１には、基板１０２の上に略Ｌ字状に曲げて形成された複数列の空気冷媒熱交換器１０３を配置し、空気冷媒熱交換器１０３の内方には送風手段である送風ファン１０４が配設されている。 As shown in FIG. 7, a heat pump unit 101 provided with a water refrigerant heat exchanger is provided with a plurality of rows of air refrigerant heat exchangers 103 formed by bending the substrate 102 in a substantially L shape, Inside the refrigerant heat exchanger 103, a blower fan 104 as a blower is disposed.
水冷媒熱交換器１０５は送風ファン１０４の下方に配置されている。また、基板１０２に載置されている空気冷媒熱交換器１０３は、連結桟１０６の座部１０６ａに載置されており、基板１０２と空気冷媒熱交換器１０３のフィンの最下端との間には隙間が生じている。 The water refrigerant heat exchanger 105 is disposed below the blower fan 104. The air refrigerant heat exchanger 103 placed on the substrate 102 is placed on the seat 106 a of the connecting bar 106, and between the substrate 102 and the lowest end of the fins of the air refrigerant heat exchanger 103. There is a gap.
また、送風ファン１０４は、空気冷媒熱交換器１０３の縦方向の中心に対して、送風ファン１０４の最上部が、空気冷媒熱交換器を備えたヒートポンプユニット１０１の上端に位置するほど上方に配されている。 In addition, the blower fan 104 is disposed above the center of the air refrigerant heat exchanger 103 in the vertical direction so that the uppermost portion of the blower fan 104 is positioned at the upper end of the heat pump unit 101 including the air refrigerant heat exchanger. Has been.
さらに、空気冷媒熱交換器１０３は複数列の集熱熱交換器で構成されており、外側列１０３ａ、内側列１０３ｂがあり、内側列１０３ｂの下方部は外側列１０３ａより所定長さ短く構成されており、下方部の空気の流通を良化している。 Further, the air refrigerant heat exchanger 103 is configured by a plurality of heat collecting heat exchangers, and includes an outer row 103a and an inner row 103b, and a lower portion of the inner row 103b is configured to be shorter than the outer row 103a by a predetermined length. The flow of air in the lower part is improved.
また図８に示すように、基板１０２の背面端板１０２ａと水冷媒熱交換器１０５の保護カバー１０７とを連結し、略Ｌ字状の空気冷媒熱交換器１０３とその外側列１０３ａ、内側列１０３ｂを受ける連結桟１０６の座部１０６ａに通風穴を明け、その通風穴により熱交換器の風路を拡大させると共に、空気冷媒熱交換器１０２に凝縮され滴下した水を速やかに基板１０２内に流水させる構造とすることで、熱交換性能を維持向上させると共に、ドレン水の処理を基板に集合させることができ、且つ、連結桟を一体形成することで、組立て作業性向上も図ることができる。 Further, as shown in FIG. 8, the rear end plate 102a of the substrate 102 and the protective cover 107 of the water refrigerant heat exchanger 105 are connected, and the substantially L-shaped air refrigerant heat exchanger 103, its outer row 103a, and inner row. Ventilation holes are made in the seat 106a of the connecting bar 106 that receives the air flow 103b, and the air passage of the heat exchanger is expanded by the ventilation holes, and the water condensed and dropped in the air refrigerant heat exchanger 102 is promptly put into the substrate 102. By adopting a structure that allows water to flow, the heat exchange performance can be maintained and improved, the drain water treatment can be gathered on the substrate, and the assembly workability can be improved by integrally forming the connecting bar. .
また、送風手段である送風ファン１０４と、仕切板１０８を介して隔離された位置には
、圧縮機１０９が配されている。
Further, a compressor 109 is disposed at a position separated from the blower fan 104 as a blower means via the partition plate 108.
しかしながら、前記従来の構成では、送風ファン１０４の位置が空気冷媒熱交換器１０３の縦方向の中心に対して、上方に配されているために、送風ファン１０４の中心より下方側は、風量が減じてしまう傾向がある。そこで、その風量減少を防ぐため、水冷媒熱交換器１０５の保護カバー１０７の投影面にある空気冷媒熱交換器１０３の内側列集熱熱交換器１０３ｂを外側列集熱熱交換器１０３ａよりも所定長さ短くして、通風抵抗を減じている。しかし、それは空気冷媒熱交換器１０３の面積を減じることであり、効率をダウンさせる要因となっている。 However, in the conventional configuration, since the position of the blower fan 104 is arranged above the center of the air refrigerant heat exchanger 103 in the vertical direction, the air volume is below the center of the blower fan 104. There is a tendency to decrease. Therefore, in order to prevent a reduction in the air volume, the inner row heat collection heat exchanger 103b of the air refrigerant heat exchanger 103 on the projection surface of the protective cover 107 of the water refrigerant heat exchanger 105 is made more than the outer row heat collection heat exchanger 103a. The ventilation resistance is reduced by shortening the predetermined length. However, that is to reduce the area of the air-refrigerant heat exchanger 103, which is a factor for reducing efficiency.
さらに、従来の構成では、基板１０２と空気冷媒熱交換器１０３の間に間隙１１０が設けられているために、送風ファン１０５で強制的に送られた空気は、空気冷媒熱交換器１０３の外側列集熱熱交換器１０３ａ、内側列集熱熱交換器１０３ｂを通過する空気と、空気冷媒熱交換器１０３下方の間隙１１０を通過する空気と分けられる。 Further, in the conventional configuration, since the gap 110 is provided between the substrate 102 and the air refrigerant heat exchanger 103, the air forcedly sent by the blower fan 105 is outside the air refrigerant heat exchanger 103. The air passing through the row heat collection heat exchanger 103 a and the inner row heat collection heat exchanger 103 b is divided into the air passing through the gap 110 below the air refrigerant heat exchanger 103.
ところが、空気冷媒熱交換器１０３下方の間隙１１０を通過する空気は、熱交換に寄与しないための、同じく効率が落ちてしまうと言う課題を有していた。また空気冷媒熱交換器１０３を受ける連結桟１０６の座部１０６ａに通風穴を明けているが、その他の部分は通風の妨害になっており、熱交換の効率を低下させているという課題があった。 However, the air passing through the gap 110 below the air refrigerant heat exchanger 103 has the problem that the efficiency is also reduced because it does not contribute to heat exchange. Although the ventilation hole is made in the seat portion 106a of the connecting beam 106 that receives the air refrigerant heat exchanger 103, the other portions are obstructed by ventilation, and there is a problem that the efficiency of heat exchange is lowered. It was.
また連結桟１０６の座部１０６ａの通風穴により、空気冷媒熱交換器１０３に凝縮され滴下した水を速やかに基板１０２内に流水させているが、その座部１０６ａが水平で多量なドレン水が常時保水されやすいため、連結桟１０６が板金の場合、錆びやすいという課題があった。 Further, the water condensed and dropped in the air refrigerant heat exchanger 103 is quickly caused to flow into the substrate 102 through the ventilation holes of the seat portion 106a of the connecting bar 106, but the seat portion 106a is horizontal and a large amount of drain water is discharged. Since water is always easily retained, there is a problem that the connecting bar 106 is easily rusted when it is a sheet metal.
本発明は、前記従来の課題を解決するものであり、ヒートポンプユニットの基板に載置された水冷媒熱交換器の後方にある空気冷媒熱交換器の通風性能を向上させ、製品の性能効率を向上させるとともに、水冷媒熱交換器を覆う保護カバーを筐体内の各部品に強固に係合させ、振動・防音性能を向上したヒートポンプ式給湯機を提供することを目的とする。 The present invention solves the above-mentioned conventional problems, improves the ventilation performance of the air refrigerant heat exchanger behind the water refrigerant heat exchanger placed on the substrate of the heat pump unit, and improves the performance efficiency of the product. It is an object of the present invention to provide a heat pump type hot water heater that is improved in vibration and sound insulation performance by improving the vibration and sound insulation performance by firmly engaging a protective cover that covers the water-refrigerant heat exchanger with each component in the housing.

水冷媒熱交換器５は、上下に２分割された発泡断熱容器１２に収納され、その外郭は保護カバー１３で覆われている。保護カバー１３の上面部には、ファンモーター固定具１４が搭載され、そのファンモーターには送風ファン１５が固定されている。 The water-refrigerant heat exchanger 5 is housed in a foam insulation container 12 that is divided into two parts in the vertical direction, and its outer shell is covered with a protective cover 13. A fan motor fixture 14 is mounted on the upper surface of the protective cover 13, and a blower fan 15 is fixed to the fan motor.
またその後方には、空気冷媒熱交換器６が基板２上に載置されている。また保護カバー１３の右側では、仕切板３と接触する折り曲げ面となる右固定部１３ａを形成し、仕切板３とねじ締結などで連結係合されている。 In addition, an air refrigerant heat exchanger 6 is placed on the substrate 2 behind the substrate. Further, on the right side of the protective cover 13, a right fixing portion 13 a serving as a bent surface that comes into contact with the partition plate 3 is formed, and is connected and engaged with the partition plate 3 by screw fastening or the like.

The left fixing portion 13b of the protective cover 13 is a substrate between the protective cover 13 and the left portion 6a of the air refrigerant heat exchanger 6 bent in a substantially L shape. 2 is screwed.
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.
圧縮機４を運転すると、高圧まで圧縮されて吐出された冷媒は、冷媒循環配管７を通り、水冷媒熱交換器５に送られ、貯湯タンクユニット（図示せず）より、接続部９を通って
きた低温水と熱交換して放熱する。これにより、加熱された低温水は、高温水となり、水循環配管８を通り、貯湯タンクユニットに送られ、高温の温水として貯湯される。
When the compressor 4 is operated, the refrigerant compressed and discharged to a high pressure passes through the refrigerant circulation pipe 7, is sent to the water refrigerant heat exchanger 5, and passes through the connection part 9 from the hot water storage tank unit (not shown). Heat is exchanged with low-temperature water that has been discharged. Thereby, the heated low temperature water turns into high temperature water, passes through the water circulation piping 8, is sent to the hot water storage tank unit, and is stored as hot hot water.
水冷媒熱交換器５から流出する冷媒は、減圧手段である膨張弁にて減圧膨張され、蒸発器である空気冷媒熱交換器６に送られ、送風ファン１５により送られた空気と熱交換して、蒸発器である空気冷媒熱交換器６を通過する間に、蒸発してガス化する。 The refrigerant flowing out of the water-refrigerant heat exchanger 5 is decompressed and expanded by an expansion valve that is a decompressing means, sent to the air refrigerant heat exchanger 6 that is an evaporator, and exchanges heat with the air sent by the blower fan 15. Thus, it evaporates and gasifies while passing through the air refrigerant heat exchanger 6 which is an evaporator.
このガス化した冷媒は、再度圧縮機４に吸入され、再度圧縮される過程を繰り返し、低温水は徐々に加熱されて、貯湯タンクに貯湯され、給湯機としての動作を行う。 The gasified refrigerant is again sucked into the compressor 4 and is repeatedly compressed, and the low-temperature water is gradually heated and stored in a hot water storage tank to operate as a hot water heater.
この時に、蒸発器である空気冷媒熱交換器６は、送風ファン１５により送られた空気と熱交換を行うことになるので、その面積は大きい方が効率が上がることとなる。 At this time, the air refrigerant heat exchanger 6 as an evaporator exchanges heat with the air sent by the blower fan 15, so that the larger the area, the higher the efficiency.
そのため、空気冷媒熱交換器６の下部を受ける連結桟を使用せずに、空気冷媒熱交換器６の最下端がいずれも基板２に載置していることで、その間隙をほとんどなくしていることとなり、空気冷媒熱交換器６を備えたヒートポンプユニットのサイズが同じ場合に、蒸発器である空気冷媒熱交換器６の高さを高くすることができ、蒸発器である空気冷媒熱交換器６の面積を最大に生かすことができる。 Therefore, the lower end of the air refrigerant heat exchanger 6 is placed on the substrate 2 without using a connecting bar that receives the lower part of the air refrigerant heat exchanger 6, so that the gap is almost eliminated. That is, when the size of the heat pump unit including the air refrigerant heat exchanger 6 is the same, the height of the air refrigerant heat exchanger 6 that is an evaporator can be increased, and the air refrigerant heat exchanger that is an evaporator. The area of 6 can be utilized to the maximum.
さらに連結桟による通風妨害もないため、空気冷媒熱交換器の下部の通風性能が向上して、給湯機としての性能効率が向上することができる。 Furthermore, since there is no airflow obstruction by the connecting bar, the airflow performance at the lower part of the air refrigerant heat exchanger is improved, and the performance efficiency as a hot water heater can be improved.
また水冷媒熱交換器５を覆う保護カバー１３の上面部には、ファンモーター固定具１４が搭載され、その上部には、上部固定具１６が係合され、上部固定具１６の一端は、上方より空気冷媒熱交換器６を挟み込んでいるとともに、上部固定具１６の上面には弾力ある緩衝材１７が貼り付けられて、筐体の天板１９により挟み込まれて強固に固定されている。 A fan motor fixture 14 is mounted on the upper surface of the protective cover 13 that covers the water-refrigerant heat exchanger 5, and an upper fixture 16 is engaged with the upper portion of the fan motor fixture 14. The air refrigerant heat exchanger 6 is further sandwiched, and an elastic cushioning material 17 is attached to the upper surface of the upper fixture 16 and is sandwiched and firmly fixed by the top plate 19 of the housing.
また送風ファン１５の振動を受ける保護カバー１３の右側では、その右固定部１３ａが仕切板３とねじ締結され、また保護カバー１３の左側では、その左固定部１３ｂが基板２とねじ締結されて、さらに保護カバー１３の前面部が基板２と筐体である外箱前板１８との間に挟み込み固定されている。 On the right side of the protective cover 13 that receives vibration of the blower fan 15, the right fixing portion 13 a is screwed to the partition plate 3, and on the left side of the protective cover 13, the left fixing portion 13 b is screwed to the substrate 2. Further, the front surface portion of the protective cover 13 is sandwiched and fixed between the substrate 2 and the outer box front plate 18 which is a casing.
そのため、運転中の送風ファン１５による振動は、保護カバー１３や空気冷媒熱交換器６や天板１９に伝播しても緩和され、製品の振動・防音性能を向上させることができる。また製品運搬中に、重量物であるファンモーター固定具１４が変形して送風ファン１５の軸ずれすることを抑えて、異常音の発生を防止することができる。 Therefore, vibration caused by the blowing fan 15 during operation is mitigated even if it propagates to the protective cover 13, the air refrigerant heat exchanger 6, and the top plate 19, thereby improving the vibration / soundproof performance of the product. In addition, it is possible to prevent the fan motor fixture 14 that is a heavy object from being deformed and being displaced from the axis of the blower fan 15 during product transportation, thereby preventing abnormal noise.
以上のことは、蒸発器である空気冷媒熱交換器６の集熱熱交換器が複数列の場合に説明したが、単列であっても同じであり、蒸発器である空気冷媒熱交換器６を基板２に載置しても、効率を向上させることができる。 The above has been described in the case where the heat collection heat exchanger of the air refrigerant heat exchanger 6 that is an evaporator is in a plurality of rows, but the same applies to a single row, and the air refrigerant heat exchanger that is an evaporator. Even if 6 is placed on the substrate 2, the efficiency can be improved.

5 and 6, on the placement surface of the substrate 2, a protective cover 13 that covers the left-side portion 6 a of the air refrigerant heat exchanger 6 bent in a substantially L shape and the heat insulating member 12 that houses the water refrigerant heat exchanger 5. A convex diaphragm-shaped fixing portion 2a having a slanting surface descending forward and having a screw hole in the slanting surface is disposed in the rear portion between the protective cover 13 and the rear portion on the left side surface of the protective cover 13. An L-shaped left fixed portion 13b that is a bent surface that is in surface contact with the inclined surface of the two convex diaphragm-shaped fixed portions 2a is formed and engaged with the screw.
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.
基板２に有する凸絞り形状の固定部２ａと、保護カバー１３の左側面に形成された左固定部１３ｂは保護カバー１３の後方部に配設されているため、ファンモーター固定具１４に近い位置で固定され、保護カバー１３での振動の伝播を抑えられ、製品の振動・防音性能の向上が図られる。 The convex diaphragm-shaped fixing portion 2a provided on the substrate 2 and the left fixing portion 13b formed on the left side surface of the protective cover 13 are disposed at the rear portion of the protective cover 13, so that the position is close to the fan motor fixture 14. And the propagation of vibration in the protective cover 13 can be suppressed, and the vibration and soundproofing performance of the product can be improved.
またサービスメンテナンス時に、水冷媒熱交換器を収納した断熱部材を覆う保護カバーを上方に取り外そうとする場合、保護カバーの左固定部は、前方に向かい、傾斜したねじ締結になっているため、空気冷媒熱交換器６の左部６ａと保護カバー１３の左側面部の狭い隙間の後方部にあるものの、前方よりドライバーを挿入しても、手が空気冷媒熱交換器６の左部６ａに当たりにくく、工具の操作ができるため、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。 In service maintenance, if you want to remove the protective cover that covers the heat insulation member that houses the water-refrigerant heat exchanger, the left fixing part of the protective cover is forward-facing and has an inclined screw fastening. Although it is in the rear part of the narrow gap between the left part 6a of the air refrigerant heat exchanger 6 and the left side surface part of the protective cover 13, even if a driver is inserted from the front, the hand hits the left part 6a of the air refrigerant heat exchanger 6 Since it is difficult and the tool can be operated, it can be easily removed and service maintenance can be improved.
