本発明は、空気調和機の室外機に関する。 The present invention relates to an outdoor unit of an air conditioner.
空気調和機の室外機では、部品コスト低減のため、底板を薄肉化することが求められている。しかし、底板を薄肉化すると、底板の強度が下がり、底板が変形するおそれがある。 In an outdoor unit of an air conditioner, it is required to reduce the thickness of the bottom plate in order to reduce component costs. However, when the bottom plate is thinned, the strength of the bottom plate is lowered and the bottom plate may be deformed.
特許文献1には、機械室載置面と熱交換器載置面に、凹部等が必要カ所に一体に設けられていて、圧縮機や室外熱交換器および送風機支持体の重量に対する強度の保持を図る空気調和機の室外機が記載されている。 In Patent Document 1, the machine room mounting surface and the heat exchanger mounting surface are integrally provided with a recess or the like where necessary, and the strength of the compressor, the outdoor heat exchanger, and the blower support is maintained.

しかしながら、圧縮機や室外熱交換器および送風機の重量による曲げ荷重は、固定用脚の間における底板全体に加わる。 However, the bending load due to the weight of the compressor, the outdoor heat exchanger, and the blower is applied to the entire bottom plate between the fixing legs.
特許文献1に記載の空気調和機の室外機は、底板の長手方向において、凸部等が設けられている箇所では強度が高いが、凹部等が設けられていない箇所では強度が低い。そのため、凸部等が設けられていない箇所で底板が変形するおそれがある。 The outdoor unit of an air conditioner described in Patent Document 1 has high strength at a location where a convex portion or the like is provided in the longitudinal direction of the bottom plate, but low strength at a location where a concave portion or the like is not provided. Therefore, there is a possibility that the bottom plate is deformed at a place where the convex portion or the like is not provided.
特許文献2に記載の空気調和機の室外機は、悪天候時に雨水が浸入し、圧縮機や電気箱が劣化するおそれがある。 In the outdoor unit of an air conditioner described in Patent Document 2, rainwater may enter during bad weather, and the compressor and the electric box may deteriorate.

図1は、実施例1に係る室外機の構成部品の説明図である。図2は、実施例1に係る室外機の機械室の拡大図である。図3は、実施例1に係る底板の構成部品詳細図である。図1に示すように、室外機の筺体は底板1、正面板2、天面板3、左側面板4、右側面板5等の板金筐体と室外熱交換器9から構成されている。 FIG. 1 is an explanatory diagram of components of the outdoor unit according to the first embodiment. FIG. 2 is an enlarged view of the machine room of the outdoor unit according to the first embodiment. FIG. 3 is a detailed diagram of components of the bottom plate according to the first embodiment. As shown in FIG. 1, the housing of the outdoor unit includes a sheet metal housing such as a bottom plate 1, a front plate 2, a top plate 3, a left side plate 4, and a right side plate 5, and an outdoor heat exchanger 9.
機械室50は、底板1、正面板2、天面板3、右側面板5および仕切り板6によって構成され、圧縮機7を格納している。送風機室51は、底板1、正面板2、天面板3、左側面板4、仕切り板6および室外機熱交換機9によって構成され、室外送風機8を格納している。 The machine room 50 includes a bottom plate 1, a front plate 2, a top plate 3, a right side plate 5 and a partition plate 6, and stores a compressor 7. The blower chamber 51 includes the bottom plate 1, the front plate 2, the top plate 3, the left side plate 4, the partition plate 6, and the outdoor unit heat exchanger 9, and stores the outdoor blower 8.
本実施例の空気調和機は、室外機に加え、室内熱交換器及び室内送風機を有する室内機(図示せず)も備えている。 The air conditioner of the present embodiment also includes an indoor unit (not shown) having an indoor heat exchanger and an indoor blower in addition to the outdoor unit.
図2に示すように、底板1には据付時の土台となる据付脚11と圧縮機固定ボルト12が取り付けられ、圧縮機7は防振ゴム13を介して圧縮機固定ボルト12に固定されている。 As shown in FIG. 2, an installation leg 11 and a compressor fixing bolt 12 that serve as a foundation at the time of installation are attached to the bottom plate 1, and the compressor 7 is fixed to the compressor fixing bolt 12 via an anti-vibration rubber 13. Yes.
機械室50と送風機室51を仕切る仕切り板6には、後述するように底板凸部貫通溝601が設けられている。 The partition plate 6 that partitions the machine room 50 and the blower chamber 51 is provided with a bottom plate convex portion through groove 601 as described later.
機械室50には、圧縮機7の重量及び駆動によって、底板1が変形するのを防ぐために、底板凸部101及び圧縮機用底板凸部105が設けられている。圧縮機固定ボルト12は、底板凸部101及び圧縮機用底板凸部105上に設置されている。底板凸部101のうち、送風機室51にあるものを送風機室底板凸部101a、機械室50にあるものを機械室底板凸部101bとする。 The machine room 50 is provided with a bottom plate convex portion 101 and a compressor bottom plate convex portion 105 in order to prevent the bottom plate 1 from being deformed by the weight and driving of the compressor 7. The compressor fixing bolt 12 is installed on the bottom plate convex portion 101 and the compressor bottom plate convex portion 105. Among the bottom plate convex portions 101, the one in the blower chamber 51 is the blower chamber bottom plate convex portion 101a, and the one in the machine chamber 50 is the machine chamber bottom plate convex portion 101b.
底板1には、主に、製品輸送時や据付運搬時の衝撃荷重(室外送風機8、室外熱交換器9及び仕切り板6を介した電装箱10による曲げモーメント)が加わる。また、製品輸送時や据付運搬時の圧縮機7への衝撃荷重が圧縮機固定ボルト12を介して底板1に加わる。圧縮機7の駆動による曲げモーメントも底板1に加わるが、製品輸送時や据付運搬時の衝撃荷重に比べて小さいため、製品輸送時や据付運搬時の衝撃荷重が底板1の変形に対しては支配的である。 The bottom plate 1 is mainly subjected to an impact load (bending moment by the electrical box 10 via the outdoor fan 8, the outdoor heat exchanger 9, and the partition plate 6) during product transportation or installation transportation. Further, an impact load on the compressor 7 during product transportation or installation transportation is applied to the bottom plate 1 via the compressor fixing bolt 12. Although the bending moment due to the drive of the compressor 7 is also applied to the bottom plate 1, it is smaller than the impact load during product transportation or installation transportation, so the impact load during product transportation or installation transportation against the deformation of the bottom plate 1 Dominant.
仮に、製品輸送時や据付運搬時の衝撃荷重に対して、長手方向において、複数の凸部で底板1を補強した場合、複数の凸部の間における底板1では強度が強化されず、底板1が変形するおそれがある。 If the bottom plate 1 is reinforced with a plurality of convex portions in the longitudinal direction against an impact load during product transportation or installation transportation, the strength is not enhanced in the bottom plate 1 between the plurality of convex portions. May be deformed.
そこで、本実施例では、据付脚11に対して垂直の方向に2本の底板凸部101を機械室50から仕切り板6を介して送風機室51まで連続して形成している。本実施例によれば、送風機室底板凸部101aと機械室底板凸部101bの間に強度が弱くなる部分がないため、圧縮機7や室外熱交換器9および室外送風機8の重量による曲げ荷重に対して、底板1の変形を抑制することができる。 Therefore, in this embodiment, two bottom plate projections 101 are continuously formed from the machine chamber 50 to the blower chamber 51 through the partition plate 6 in a direction perpendicular to the installation leg 11. According to the present embodiment, since there is no weakened portion between the blower chamber bottom plate convex portion 101a and the machine room bottom plate convex portion 101b, the bending load due to the weight of the compressor 7, the outdoor heat exchanger 9, and the outdoor blower 8 On the other hand, the deformation of the bottom plate 1 can be suppressed.
なお、言い換えると、底板凸部101は、据付脚11に対して垂直の方向に機械室50から送風機室51まで貫通した構造である。また、底板凸部101は、送風機室底板凸部101aと機械室底板凸部101bを有し、1つの凸部として形成されている。 In other words, the bottom plate convex portion 101 has a structure penetrating from the machine room 50 to the blower room 51 in a direction perpendicular to the installation leg 11. The bottom plate convex portion 101 has a blower chamber bottom plate convex portion 101a and a machine chamber bottom plate convex portion 101b, and is formed as one convex portion.
底板凸部101の高さは機械室50から送風機室51まで一律(段差無く連続)で、又、直線状または折れ線形状とすることが望ましい。一律(段差無く連続)とは、底板凸部101に大きな段差がないことを意味し、底板凸部101の高さが徐々に変化する場合を含む。 It is desirable that the height of the bottom plate convex portion 101 is uniform (continuous without a step) from the machine room 50 to the blower room 51, and is linear or broken line. Uniform (continuous without steps) means that there is no large step in the bottom plate convex portion 101, and includes the case where the height of the bottom plate convex portion 101 gradually changes.
本実施例において、底板1の長手方向とは、室外送風機8の軸に対して垂直な方向をいう。 In the present embodiment, the longitudinal direction of the bottom plate 1 refers to a direction perpendicular to the axis of the outdoor fan 8.
特に、底板1の長手方向において、室外送風機8の支持部及び圧縮機7の支持部(圧縮機固定ボルト12)の間に位置する底板1で曲げモーメントが大きくなるため、底板凸部101は、底板1の長手方向において、少なくとも室外送風機8の支持部及び圧縮機7の支持部(圧縮機固定ボルト12)の間に位置する底板1に設けられている。つまり、底板凸部101は、少なくとも室外送風機8の支持部から圧縮機7の支持部(圧縮機固定ボルト12)まで連続して形成されている。 In particular, in the longitudinal direction of the bottom plate 1, the bending moment increases at the bottom plate 1 located between the support portion of the outdoor fan 8 and the support portion of the compressor 7 (compressor fixing bolt 12). In the longitudinal direction of the bottom plate 1, the bottom plate 1 is provided at least between the support portion of the outdoor fan 8 and the support portion (compressor fixing bolt 12) of the compressor 7. That is, the bottom plate convex portion 101 is continuously formed from at least the support portion of the outdoor fan 8 to the support portion (compressor fixing bolt 12) of the compressor 7.
なお、底板1の長手方向において、据付脚11の間における底板1全体に底板凸部101を設けることが望ましい。しかし、据付脚11付近の底板では曲げモーメントが比較的小さいため、付脚11の間における底板1全体に底板凸部101を設けなくてもよい。本実施例では、機械室底板凸部101bを機械室50側に位置する据付脚11を跨って構成しているが、送風機室底板凸部101aは送風機室51側に位置する据付脚11を跨らずに構成している。 In addition, in the longitudinal direction of the baseplate 1, it is desirable to provide the baseplate convex part 101 in the whole baseplate 1 between the installation legs 11. FIG. However, since the bending moment is relatively small in the bottom plate in the vicinity of the installation leg 11, it is not necessary to provide the bottom plate convex portion 101 on the entire bottom plate 1 between the attachment legs 11. In the present embodiment, the machine room bottom plate convex portion 101b is configured to straddle the installation leg 11 located on the machine room 50 side, but the blower chamber bottom plate convex portion 101a straddles the installation leg 11 located on the blower chamber 51 side. It is configured without.
本実施例の室外熱交換器9は、底板1の長手方向において、2つの据付脚11の間に跨って位置している。つまり、室外熱交換器9は、2つの据付脚11に支持されており、室外熱交換器9による曲げモーメントが底板1には掛からない。従って、室外熱交換器9は、底板凸部101の上には位置していない。 The outdoor heat exchanger 9 of the present embodiment is located between the two installation legs 11 in the longitudinal direction of the bottom plate 1. That is, the outdoor heat exchanger 9 is supported by the two installation legs 11, and the bending moment due to the outdoor heat exchanger 9 is not applied to the bottom plate 1. Therefore, the outdoor heat exchanger 9 is not located on the bottom plate convex portion 101.
機械室底板凸部101bには、圧縮機7の重量及び駆動による底板1の変形を防ぐために、凹部102及び突起部103が設けられている。 The machine room bottom plate convex portion 101b is provided with a concave portion 102 and a protruding portion 103 in order to prevent deformation of the bottom plate 1 due to the weight and driving of the compressor 7.
なお、本実施例では、底板凸部101を上に凸形状(機械室50及び送風機室51側に凸形状)としているが、底板の強度を向上できる形状であれば、他の形状であってもよい。例えば、底板凸部101を下に凸形状で構成してもよい。 In this embodiment, the bottom plate convex portion 101 is convex upward (convex shape toward the machine chamber 50 and the blower chamber 51), but any other shape can be used as long as it can improve the strength of the bottom plate. Also good. For example, the bottom plate convex portion 101 may be formed in a convex shape downward.
機械室底板凸部101bには、製品運転中に圧縮機7への吸込み冷媒で冷やされて生じた除湿水が圧縮機7本体から滴下する。本実施例では、機械室底板凸部101bから排水口106の方向に向かって徐々に低くなるように段差が設けており、運転中に圧縮機7に付着した除湿水が機械室底板凸部101b上に滴下した場合でも底板1の排水口106に向かうため、円滑に排水を行うことができる。 Dehumidified water generated by cooling with the refrigerant sucked into the compressor 7 during product operation is dropped from the compressor 7 main body onto the machine room bottom plate convex portion 101b. In this embodiment, a step is provided so as to gradually become lower from the machine room bottom plate convex portion 101b toward the drain port 106, and the dehumidified water adhering to the compressor 7 during operation becomes the machine room bottom plate convex portion 101b. Even when it is dropped on the top, it goes to the drain port 106 of the bottom plate 1, so that it can be drained smoothly.
図4及び図5は、実施例1に係る部品共用化を目的とした圧縮機固定ボルト穴の位置とその補強構造の説明図である。本実施例では、図4及び図5に示すように、圧縮機固定ボルト穴104の位置を変更するだけで、寸法が異なる複数の圧縮機7を搭載でき、底板1及び圧縮機固定ボルト12並びにこれらの製造設備の共用化を図っている。 4 and 5 are explanatory views of the positions of the compressor fixing bolt holes and their reinforcing structures for the purpose of sharing parts according to the first embodiment. In this embodiment, as shown in FIGS. 4 and 5, a plurality of compressors 7 having different dimensions can be mounted only by changing the position of the compressor fixing bolt hole 104, and the bottom plate 1, the compressor fixing bolt 12 and the like. These production facilities are shared.
底板を薄肉化すると、底板1そのものの強度の低下に加え、薄肉化した分だけ加締め部の摩擦が低下し、圧縮機固定ボルト12の底板1への固定強度が低下する。
輸送時や据付時の衝撃荷重が製品に加わると圧縮機7もその衝撃を受けるため、圧縮機固定ボルト12にはそれによる横荷重が加わる。この時、圧縮機固定ボルト12に対向する面が広いと、圧縮機固定ボルト12に加わった圧縮機7からの荷重により、圧縮機固定ボルト穴の周囲の底板1が変形し、圧縮機固定ボルト12が底板に対して歪んだ状態になるおそれがある。すると、圧縮機固定ボルト12の固定が緩み、圧縮機7が適切に駆動できなくなる可能性がある。
When the bottom plate is thinned, in addition to a decrease in the strength of the bottom plate 1 itself, the friction of the caulking portion is reduced by the thinned portion, and the fixing strength of the compressor fixing bolt 12 to the bottom plate 1 is reduced.
When an impact load during transportation or installation is applied to the product, the compressor 7 also receives the impact, so that a lateral load is applied to the compressor fixing bolt 12. At this time, if the surface facing the compressor fixing bolt 12 is wide, the bottom plate 1 around the compressor fixing bolt hole is deformed by the load from the compressor 7 applied to the compressor fixing bolt 12, and the compressor fixing bolt There is a possibility that 12 is distorted with respect to the bottom plate. Then, the fixing of the compressor fixing bolt 12 may be loosened, and the compressor 7 may not be driven properly.
特に、底板1の板厚が異なる複数の製品に対して、1種類の圧縮機固定ボルト12を共用して使用する場合、板厚が薄い底板1では、特に、圧縮機固定ボルト穴104が変形しやすい。 In particular, when a single type of compressor fixing bolt 12 is used in common for a plurality of products having different thicknesses of the bottom plate 1, the compressor fixing bolt hole 104 is deformed particularly in the bottom plate 1 having a thin plate thickness. It's easy to do.
そこで、図4及び図5に示すように、機械室底板凸部101bには凹部102及び突起部103に加え、圧縮機固定ボルト穴104が設けられている。つまり、圧縮機7の支持部(圧縮機固定ボルト12)の少なくとも一部は底板凸部101の上に位置する。本実施例によれば、圧縮機固定ボルト穴104が、底板1のうち、強度が高い機械室底板凸部101bに設けられるため、圧縮機固定ボルト穴104の変形を抑制することができる。 Therefore, as shown in FIGS. 4 and 5, the machine chamber bottom plate convex portion 101 b is provided with a compressor fixing bolt hole 104 in addition to the concave portion 102 and the protruding portion 103. That is, at least a part of the support portion (compressor fixing bolt 12) of the compressor 7 is located on the bottom plate convex portion 101. According to the present embodiment, since the compressor fixing bolt hole 104 is provided in the machine room bottom plate convex portion 101b of the bottom plate 1 having high strength, deformation of the compressor fixing bolt hole 104 can be suppressed.
底板凸部101は、機械室50から送風機室51まで貫通して設けられる分、底板凸部101の面積が大きくなる。すると、機械室底板凸部101bを設けたとしても、圧縮機7への衝撃荷重によって、機械室底板凸部101bの面上における変形を防ぐことができないおそれがある。 The area of the bottom plate convex portion 101 is increased as the bottom plate convex portion 101 is provided so as to penetrate from the machine room 50 to the blower chamber 51. Then, even if the machine room bottom plate convex portion 101b is provided, there is a possibility that deformation on the surface of the machine room bottom plate convex portion 101b cannot be prevented by an impact load to the compressor 7.
図6は、実施例1に係る圧縮機固定ボルト及び圧縮機固定ボルト穴の説明図である。図7は、実施例1に係る圧縮機固定ボルト及び圧縮機固定ボルト穴の拡大図である。本実施例では、図4乃至図7に示すように、圧縮機固定ボルト12の周囲である機械室底板凸部101b上に凹部102を設けている。 FIG. 6 is an explanatory diagram of the compressor fixing bolt and the compressor fixing bolt hole according to the first embodiment. FIG. 7 is an enlarged view of the compressor fixing bolt and the compressor fixing bolt hole according to the first embodiment. In this embodiment, as shown in FIGS. 4 to 7, a recess 102 is provided on a machine room bottom plate projection 101 b around the compressor fixing bolt 12.
本実施例によれば、機械室底板凸部101bの強度を高めることができ、圧縮機7が駆動することによる引張り荷重に対する強度をさらに高めることができる。 According to the present embodiment, the strength of the machine room bottom plate convex portion 101b can be increased, and the strength against the tensile load due to the driving of the compressor 7 can be further increased.
なお、仮に凹部102が防振ゴム13に干渉すると十分な制振効果が得られないとともに防振ゴム13の直径を自由に選択できなくなるなどの不具合が生じる。従って、凹部102を防振ゴム13に干渉しないよう防振ゴム13と逆方向に凹んでいる構造としている。 If the recess 102 interferes with the vibration isolating rubber 13, a sufficient vibration damping effect cannot be obtained, and the diameter of the vibration isolating rubber 13 cannot be freely selected. Therefore, the concave portion 102 is recessed in the opposite direction to the anti-vibration rubber 13 so as not to interfere with the anti-vibration rubber 13.
底板1を薄肉化すると、圧縮機固定ボルト12と底板1との摩擦力が低下し、圧縮機固定ボルト12への底板1への固定が緩むおそれがある。そこで、本実施例では、図4乃至図6に示すように、機械室底板凸部101bは、圧縮機7の支持部(圧縮機固定ボルト12)の下方に突起部103を有する。言い換えると、機械室底板凸部101bのうち、圧縮機7の支持部(圧縮機固定ボルト12)との接合面に突起部103を有する。本実施例によれば、圧縮機固定ボルト12の加締め時に突起部103が潰れて摩擦力が増え 回転方向の強度を向上させることができる。 When the bottom plate 1 is thinned, the frictional force between the compressor fixing bolt 12 and the bottom plate 1 is lowered, and the fixing to the compressor fixing bolt 12 to the bottom plate 1 may be loosened. Therefore, in the present embodiment, as shown in FIGS. 4 to 6, the machine room bottom plate convex portion 101 b has a protrusion 103 below the support portion (compressor fixing bolt 12) of the compressor 7. In other words, of the machine room bottom plate convex portion 101b, the projection 103 is provided on the joint surface with the support portion (compressor fixing bolt 12) of the compressor 7. According to the present embodiment, when the compressor fixing bolt 12 is caulked, the protrusion 103 is crushed and the frictional force is increased, so that the strength in the rotation direction can be improved.
本実施例では、底板凸部101を機械室50から送風機室51まで貫通した構造としているため、仕切り板6で機械室50と送風機室51を仕切っても、底板1と仕切り板6の間に隙間が発生する。すると、悪天候時に送風機室51から機械室50へ雨水が浸入し、圧縮機7や電気箱10が劣化するおそれがある。 In the present embodiment, since the bottom plate convex portion 101 has a structure penetrating from the machine chamber 50 to the blower chamber 51, the partition plate 6 divides the machine chamber 50 and the blower chamber 51 between the bottom plate 1 and the partition plate 6. A gap occurs. Then, rainwater may enter the machine room 50 from the blower room 51 during bad weather, and the compressor 7 and the electric box 10 may be deteriorated.
そこで、本実施例では、図1に示すように、底板凸部101は上に凸形状(機械室50及び送風機室51側に凸形状)であり、仕切り板6は底板凸部101が貫通する底板凸部貫通溝601を有する。つまり、底板凸部101の一部は底板凸部貫通溝601に位置する。本実施例によれば、底板1の変形を抑制しつつ、仕切り板6側で機械室50と送風機室51を仕切る構造とし、機械室50への水の浸入を減らしている。 Therefore, in this embodiment, as shown in FIG. 1, the bottom plate convex portion 101 has a convex shape upward (convex shape on the machine chamber 50 and blower chamber 51 side), and the partition plate 6 penetrates the bottom plate convex portion 101. A bottom plate convex portion through groove 601 is provided. That is, a part of the bottom plate convex portion 101 is located in the bottom plate convex portion through groove 601. According to the present embodiment, the machine room 50 and the blower room 51 are separated on the partition plate 6 side while suppressing the deformation of the bottom plate 1, and the intrusion of water into the machine room 50 is reduced.
さらに、圧縮機7の運転中の振動による音の発生を抑制するために、底板1と仕切り板6の間に断熱シートを挟んでいる。断熱シートは底板1又は仕切り板6のどちらか一方に貼り付けられている。底板1と仕切り板6の間に断熱シートに挟むことで、悪天候時に送風機室51から機械室50へ雨水が浸入する量を抑制することもできる。 Further, in order to suppress the generation of sound due to vibration during operation of the compressor 7, a heat insulating sheet is sandwiched between the bottom plate 1 and the partition plate 6. The heat insulating sheet is affixed to either the bottom plate 1 or the partition plate 6. By sandwiching the heat insulating sheet between the bottom plate 1 and the partition plate 6, the amount of rainwater entering from the blower chamber 51 to the machine chamber 50 during bad weather can be suppressed.
圧縮機7には吸込み側の戻り冷媒の気液分離を行うSタンク(図示せず)が付いているものが一般的であり、このSタンクによって圧縮機固定ボルト12に加わる質量がアンバランスになる。すると、Sタンク近傍の2箇所の防振ゴム13の潰れ量は残り1カ所に比べ大きくなり、圧縮機7が傾いて底板1に設置される可能性がある。そこで、圧縮機固定ボルト12が設置される2本の底板凸部101の高さを1mm乃至2mmの高さの違いを設けて構成してもよい。 The compressor 7 is generally provided with an S tank (not shown) for performing gas-liquid separation of the return refrigerant on the suction side, and the mass applied to the compressor fixing bolt 12 by this S tank is unbalanced. Become. Then, the amount of crushing of the anti-vibration rubber 13 at two locations in the vicinity of the S tank becomes larger than that at the remaining one location, and the compressor 7 may be inclined and installed on the bottom plate 1. Therefore, the height of the two bottom plate projections 101 on which the compressor fixing bolts 12 are installed may be configured with a difference in height of 1 mm to 2 mm.
なお、底板凸部101の代わりに、底板1が上に凹形状(機械室50及び送風機室51側に凹形状)である底板凹部を有する構造としてもよい。この場合、底板凹部を設けることで生まれた隙間(仕切り板6と底板1の間の空間)を通って、送風機室51から機械室50へ水が浸入する。そこで、仕切り板6に底板凹部の中に位置する底板凹部突起部を設ける。底板凹部突起部によって仕切り板6と底板1の間の空間を埋めることができるため、機械室50への水の浸入を減らすことができる。 Instead of the bottom plate convex portion 101, the bottom plate 1 may have a bottom plate concave portion having a concave shape on the top (concave shape on the machine chamber 50 and the blower chamber 51 side). In this case, water enters the machine chamber 50 from the blower chamber 51 through a gap (a space between the partition plate 6 and the bottom plate 1) created by providing the bottom plate recess. Therefore, the partition plate 6 is provided with a bottom plate recess projection located in the bottom plate recess. Since the space between the partition plate 6 and the bottom plate 1 can be filled by the bottom plate recess projection, water intrusion into the machine room 50 can be reduced.
図3に示すように、底板1を凹凸形状とし、底板1の凸形状部分の上に、底板凸部101を設けてもよい。 As shown in FIG. 3, the bottom plate 1 may have an uneven shape, and the bottom plate convex portion 101 may be provided on the convex portion of the bottom plate 1.
底板凸部101の幅(底板1の短手方向における長さ)は、室外熱交換器9の幅よりも狭いことが望ましい。 The width of the bottom plate convex portion 101 (the length of the bottom plate 1 in the short direction) is preferably narrower than the width of the outdoor heat exchanger 9.
本実施例では、底板凸部101の高さが機械室50から送風機室51まで一律である場合について説明したが、必ずしも一律である場合だけでなく、高さを変えてもよい。例えば、圧縮機7及びSタンク(図示せず)の荷重バランス上の理由から、底板送風機室側凸部101aの高さを底板機械室側凸部101bよりも高くしてもよい。 In the present embodiment, the case where the height of the bottom plate convex portion 101 is uniform from the machine chamber 50 to the blower chamber 51 has been described, but the height may be changed as well as the case where it is not necessarily uniform. For example, for the reason of load balance between the compressor 7 and the S tank (not shown), the height of the bottom plate fan chamber side convex portion 101a may be made higher than that of the bottom plate machine chamber side convex portion 101b.
本実施例において実施例1と同様の構成要素についての説明は省略する。図8は、実施例2に係る底板の構成部品詳細図である。本実施例では、図8に示すように、2本の底板凸部101を設けており、そのうち、一方の底板凸部101にのみ圧縮機固定ボルト穴104を設けている。すなわち、他方の底板凸部101と圧縮機用底板凸部105は別体で構成している。 In the present embodiment, description of the same components as those in the first embodiment will be omitted. FIG. 8 is a detailed diagram of components of the bottom plate according to the second embodiment. In this embodiment, as shown in FIG. 8, two bottom plate projections 101 are provided, and only one bottom plate projection 101 is provided with a compressor fixing bolt hole 104. That is, the other bottom plate convex portion 101 and the compressor bottom plate convex portion 105 are configured separately.
圧縮機7には吸込み側の戻り冷媒の気液分離を行うSタンクが付いているものが一般的であり、このSタンクによって圧縮機固定ボルト12に加わる質量がアンバランスになる。すると、Sタンク近傍の2箇所の防振ゴム13の潰れ量は残り1カ所に比べ大きくなる。 The compressor 7 is generally provided with an S tank that performs gas-liquid separation of the return refrigerant on the suction side, and the mass applied to the compressor fixing bolt 12 is unbalanced by the S tank. Then, the amount of crushing of the anti-vibration rubber 13 at two locations near the S tank becomes larger than the remaining one.
そこで、室外熱交換器9側に位置する圧縮機用底板凸部105の高さを、圧縮機固定ボルト12が設置される底板凸部101及び他の圧縮機用底板凸部105に対して低くしている。さらに、高さを変えた圧縮機用底板凸部105を底板凸部101に対して別体で構成しているため、2本の底板凸部101の高さを同じ高さに保つことができる。 Therefore, the height of the bottom plate convex portion 105 for the compressor located on the outdoor heat exchanger 9 side is set lower than the bottom plate convex portion 101 on which the compressor fixing bolt 12 is installed and the other bottom plate convex portions 105 for the compressor. doing. Furthermore, since the bottom plate convex part 105 for compressors which changed height is comprised with the bottom plate convex part 101 separately, the height of the two bottom board convex parts 101 can be kept at the same height. .
2本の底板凸部101と独立した1本の圧縮機用底板凸部105の高さは、同一或いは1カ所のみが1mm乃至2mm低くなっているため、圧縮機7の質量アンバランスに対応できるようになっている。 The height of one compressor bottom plate convex portion 105 independent of the two bottom plate convex portions 101 is the same or only one place is lowered by 1 mm to 2 mm, so that it can cope with the mass unbalance of the compressor 7. It is like that.
なお、底板凸部101と圧縮機用底板凸部105はそれぞれが独立しており、底板1の高さが不連続となる。しかし、当該境界部分は据付脚11の真上或いは近傍であり、先述の輸送時や据付時の衝撃荷重が発生した場合でも応力集中はしない位置に配置されている。 In addition, the baseplate convex part 101 and the baseplate convex part 105 for compressors are each independent, and the height of the baseplate 1 becomes discontinuous. However, the boundary portion is directly above or in the vicinity of the installation leg 11 and is arranged at a position where no stress concentration occurs even when the impact load during the transportation or installation described above occurs.
