特開平８−２８５４３９号公報JP-A-8-285439

前記従来の冷蔵庫では、機械室の側面の開口を通して良好な機械室内の通風を行うことができるが、単に側面板に開口を形成した場合、側面板が歪み、冷蔵庫の側面が見えるように据付けられた際に、外観が悪くなってしまう。   In the conventional refrigerator, good ventilation in the machine room can be performed through the opening on the side of the machine room, but if the opening is simply formed on the side plate, the side plate is distorted and installed so that the side of the refrigerator can be seen. The appearance will deteriorate.

また、前記従来の冷蔵庫では、開口を複数個の穴で構成することにより側面板の剛性向上を図ることが記載されているが、この複数個の開口は側面板の平坦面上に単に開口されているのみであるため、開口を設けたことによる側面板の剛性の低下は免れず、冷蔵庫本体の強度上の信頼性を確保することが難しい。   Further, in the conventional refrigerator, it is described that the rigidity of the side plate is improved by configuring the opening with a plurality of holes, but the plurality of openings are simply opened on the flat surface of the side plate. Therefore, a reduction in rigidity of the side plate due to the provision of the opening is inevitable, and it is difficult to ensure reliability in the strength of the refrigerator body.

また、補強材３７，３８の背面部の端部３７ｂ，３８ｂを上記断熱材２４の充填された冷蔵庫本体１の機械室２の上方に位置する機械室の上方部壁１ｂと側面板９，１０の背面折曲げ部９ｃ，１０ｃ（図示省略）の間に螺子によって固定保持している。すなわち、機械室の上方部壁１ｂと側面板９，１０の背面折曲げ部９ｃ，１０ｃで、補強材３７，３８の背面部の端部３７ｂ，３８ｂを保持する第二の保持部を構成している。 Further, the rear end portions 37b and 38b of the reinforcing members 37 and 38 are located above the machine room 2 of the refrigerator main body 1 filled with the heat insulating material 24, and the upper wall 1b and the side plates 9 and 10 of the machine room. Are fixedly held by screws between the back bent portions 9c and 10c (not shown) . That is, the upper part wall 1b of the machine room and the back side bent parts 9c, 10c of the side plates 9, 10 constitute a second holding part for holding the end parts 37b, 38b of the back part of the reinforcing members 37, 38. ing.

なお、補強材３８の背面部の端部３８ｂ（図示省略）は、上記補強材３７の背面部の端部３７ｂと左右対称に形成されたものである。これらの構造によって、補強材３７，３８は充分に強度を発揮でき、側面板９，１０の剛性の低下を防ぎ、冷蔵庫本体１の強度上の信頼性を確保している。   Note that an end portion 38 b (not shown) of the back surface portion of the reinforcing member 38 is formed symmetrically with the end portion 37 b of the back surface portion of the reinforcing material 37. With these structures, the reinforcing members 37 and 38 can sufficiently exhibit strength, prevent a decrease in rigidity of the side plates 9 and 10, and ensure the reliability of the refrigerator body 1 in strength.

また、前記開口９ｂ，１０ｂが形成された側面板９，１０の機械室部は、上記機械室の上方部壁１ｂおよび奥壁１ｃと、前記補強材３７，３８によって隙間無く囲まれており、更に、前記開口９ｂ，１０ｂは、前記補強材３７，３８および奥壁１ｃの近くに設けられている。これによって、両側面の側面板９，１０の機械室部の強度が確保され、開口９ｂ，１０ｂによる側面板９，１０の歪みを防止することができる。ここで、側面板９，１０の歪み防止を考慮した場合、前記補強材３７，３８または上記機械室の上方部壁１ｂおよび奥壁１ｃの近くに設けられていれば良い。   Moreover, the machine room part of the side plates 9 and 10 in which the openings 9b and 10b are formed is surrounded by the upper part wall 1b and the back wall 1c of the machine room and the reinforcing members 37 and 38 without a gap, Further, the openings 9b and 10b are provided near the reinforcing members 37 and 38 and the back wall 1c. Thereby, the strength of the machine room portion of the side plates 9 and 10 on both sides is ensured, and distortion of the side plates 9 and 10 due to the openings 9b and 10b can be prevented. Here, when the prevention of distortion of the side plates 9 and 10 is taken into consideration, it is only necessary to be provided near the reinforcing members 37 and 38 or the upper wall 1b and the back wall 1c of the machine room.

前記両側面の側面板９，１０の下面部もしくはこの下面部に位置する補強材３７，３８に、機械室底面板７の両端が固定されて側面板９，１０を補強する構造としている。   Both ends of the machine room bottom surface plate 7 are fixed to the lower surface portions of the side surface plates 9 and 10 on both side surfaces or the reinforcing members 37 and 38 located on the lower surface portions to reinforce the side surface plates 9 and 10.

また、前記開口９ｂ，１０ｂには、カバー４１を設けられ、このカバー４１には通気可能なルーバー４１ａを有し、このルーバー４１ａの方向は下向または後ろ方向に向けてある。   The openings 9b and 10b are provided with a cover 41. The cover 41 has a louver 41a that allows ventilation, and the direction of the louver 41a is directed downward or rearward.

次に、機械室底面板７は、側面板の下面折曲げ部９ａ，１０ａと補強材３７，３８に螺子あるいはボルトなどにより固着されている。この機械室底面板７及び本体底板３には脚２７，２８が取付けられており、機械室底面板７と床面２９（図８参照）との間には脚２７，２８により空隙が形成される。そして、冷蔵庫本体１の後部は脚２７により機械室底面板７及び側面板９，１０を介して支持され、冷蔵庫本体１の前部は脚２８により本体底板３を介して支持される。   Next, the machine room bottom plate 7 is fixed to the lower surface bent portions 9a, 10a of the side plates and the reinforcing members 37, 38 with screws or bolts. Legs 27 and 28 are attached to the machine room bottom plate 7 and the main body bottom plate 3, and a space is formed between the machine room bottom plate 7 and the floor surface 29 (see FIG. 8) by the legs 27 and 28. The The rear portion of the refrigerator body 1 is supported by the legs 27 via the machine room bottom plate 7 and the side plates 9 and 10, and the front portion of the refrigerator body 1 is supported by the legs 28 via the body bottom plate 3.

本実施例における冷凍サイクルは、図４に示すように、圧縮機６，凝縮器４，露付防止パイプ３０，キャピラリーチューブ３１，蒸発器３２及び圧縮機６の順に接続されて構成されている。この冷凍サイクルにおいては、従来一般に用いられている埋め込み型凝縮器を削除し、機械室内の凝縮器４に集約した凝縮器としている。これによって、安価でリサイクル性の優れた冷蔵庫とすることができる。なお、凝縮器を機械室内の凝縮器４に集約できた主な理由は、後述するように、側面に開口を形成して機械室内への通風を良好にしたこと、クロスフィン型熱交換器を凝縮器４に採用して伝熱面積を格段に増大したこと、等によるものである。   As shown in FIG. 4, the refrigeration cycle in the present embodiment is configured by connecting a compressor 6, a condenser 4, a dew prevention pipe 30, a capillary tube 31, an evaporator 32 and a compressor 6 in this order. In this refrigeration cycle, an embedded condenser that has been conventionally used is eliminated, and the condenser is integrated in the condenser 4 in the machine room. Thereby, it is possible to obtain a refrigerator that is inexpensive and excellent in recyclability. The main reasons for condensing the condenser in the condenser 4 in the machine room are that, as will be described later, an opening was formed on the side surface to improve ventilation, and a cross fin type heat exchanger was installed. This is due to the fact that the heat transfer area is greatly increased by adopting the condenser 4.

凝縮器４は、図６に示すように、蛇行状の冷媒パイプ３３に平板状の放熱フィン３４が狭いピッチで多数設けられたクロスフィン型熱交換器で構成されている。これにより、凝縮器４は、通風抵抗は増加するが、放熱面積を大きく確保できるものである。この凝縮器４のピッチは本実施例では１.５mmであり、フィンピッチの範囲としては１.３mmから１.８mmの範囲が好ましい。露付防止パイプ３０は、冷蔵庫本体１の前面開口部に沿って外箱２１と断熱材２４との間に配置され、外箱２１の前面開口部分への露付を防止するものである。なお、凝縮器４は、図示例では、全体がＬ字形状に形成されているものを用いているが、矩形状等に形成されているものを用いてもよい。Ｌ字状の凝縮器を採用する場合には、その他辺を機械室底面板７に対向させ、機械室底面板７に開口を形成することが好ましい。   As shown in FIG. 6, the condenser 4 is constituted by a cross fin type heat exchanger in which a large number of flat plate-like heat radiation fins 34 are provided at a narrow pitch on a meandering refrigerant pipe 33. Thereby, although the ventilation resistance increases, the condenser 4 can ensure a large heat radiation area. The pitch of the condenser 4 is 1.5 mm in this embodiment, and the fin pitch range is preferably from 1.3 mm to 1.8 mm. The dew prevention pipe 30 is disposed between the outer box 21 and the heat insulating material 24 along the front opening of the refrigerator main body 1 and prevents dew condensation on the front opening of the outer box 21. In the illustrated example, the condenser 4 that is formed in an L shape as a whole is used, but a condenser that is formed in a rectangular shape or the like may be used. When an L-shaped condenser is employed, it is preferable that the other side is opposed to the machine room bottom plate 7 and an opening is formed in the machine room bottom plate 7.

而して、冷凍サイクルにおける冷媒は、圧縮機６で圧縮されて高温，高圧となって凝縮器４に至り、凝縮器４で放熱された後に、露付防止パイプ３０で外箱の前面を加熱して露付を防止し、キャピラリーチューブ３１で減圧されて蒸発器３２に至り、ここで蒸発されて貯蔵室２２周囲から熱を奪い、低温，低圧の状態となって圧縮機６に戻り、以下これを繰り返すことにより冷却運転が行われる。   Thus, the refrigerant in the refrigeration cycle is compressed by the compressor 6 to become high temperature and high pressure, reaches the condenser 4, and after being dissipated by the condenser 4, the front surface of the outer box is heated by the dew prevention pipe 30. Thus, dew condensation is prevented and the pressure is reduced by the capillary tube 31 to the evaporator 32, where it is evaporated and takes heat from the surroundings of the storage chamber 22 to return to the compressor 6 in a low temperature and low pressure state. The cooling operation is performed by repeating this.

圧縮機６及び凝縮器４は、図１及び図２に示すように、機械室２内の左右両側に配置され、機械室２を構成する両側面の側面板９，１０に対向している。仕切り板１３は、機械室２内を左右に仕切るものであり、凝縮器４と圧縮機６の間に配置されている。この仕切り板１３の中央部には、円形穴が形成されており、この中に送風機５のファン５ａが配置されている。送風機５は、ファン５ａとファンモータ５ｂとを備えて構成され、仕切り板１３に一体的に組み込まれている。この送風機５は、ファンモータ５ｂに通電してファン５ａを回転し、これにより機械室２内の空気を仕切り板１３を介して左右方向に通風する。送風機５の吸込側には、凝縮器４が配置され、送風機５の吸込空気により凝縮器４が冷却される。送風機５の吐出側には圧縮機６が配置され、送風機５の吐出空気により圧縮機６が冷却される。   As shown in FIGS. 1 and 2, the compressor 6 and the condenser 4 are disposed on both the left and right sides in the machine room 2, and face the side plates 9 and 10 on both side surfaces constituting the machine room 2. The partition plate 13 partitions the inside of the machine room 2 to the left and right, and is disposed between the condenser 4 and the compressor 6. A circular hole is formed in the central portion of the partition plate 13, and the fan 5a of the blower 5 is disposed therein. The blower 5 includes a fan 5a and a fan motor 5b, and is integrally incorporated in the partition plate 13. The blower 5 energizes the fan motor 5 b to rotate the fan 5 a, thereby ventilating the air in the machine room 2 in the left-right direction via the partition plate 13. The condenser 4 is disposed on the suction side of the blower 5, and the condenser 4 is cooled by the suction air of the blower 5. A compressor 6 is disposed on the discharge side of the blower 5, and the compressor 6 is cooled by the discharge air of the blower 5.

蒸発皿１４は、圧縮機６の上部に設けられ、冷蔵庫本体１内の蒸発器３２からの除霜水を溜めるものである。蒸発皿１４内に溜められた除霜水は圧縮機６の熱によって蒸発される。   The evaporating dish 14 is provided in the upper part of the compressor 6 and stores defrosted water from the evaporator 32 in the refrigerator main body 1. The defrost water stored in the evaporating dish 14 is evaporated by the heat of the compressor 6.

冷蔵庫本体１の背面両側には空気が通る通気段部１７，１８が形成されている。この通気段部１７，１８は、側面板９，１０と背面板１１とが交差する稜線１６に沿って延びるように形成され、しかも機械室カバー８を含む冷蔵庫の全高にわたり形成されている。   Ventilation steps 17 and 18 through which air passes are formed on both sides of the back surface of the refrigerator body 1. The ventilation step portions 17 and 18 are formed so as to extend along the ridgeline 16 where the side plates 9 and 10 and the back plate 11 intersect, and are formed over the entire height of the refrigerator including the machine room cover 8.

側面板９，１０の機械室２を構成する部分には、凝縮器４及び圧縮機６に対向するように、開口９ｂ，１０ｂが形成されており、開口９ｂ，１０ｂの高さ方向の位置は、前記蒸発皿１４と通風方向に重ならない位置で且つ圧縮機の中心の高さより低い位置に形成されており、蒸発皿１４の妨げによって通風抵抗が増えずに圧縮機６に通風がされるようにしている。これによって、圧縮機６の熱を効率良く放熱することができ、冷蔵庫の消費電力量を抑制することができる。   Openings 9b and 10b are formed in the portions of the side plates 9 and 10 constituting the machine room 2 so as to face the condenser 4 and the compressor 6, and the positions of the openings 9b and 10b in the height direction are The evaporating dish 14 is formed at a position that does not overlap the ventilation direction and lower than the center height of the compressor, and the ventilation resistance is not increased by the obstruction of the evaporating dish 14 so that the compressor 6 can be ventilated. I have to. Thereby, the heat of the compressor 6 can be efficiently radiated and the power consumption of the refrigerator can be suppressed.

また、上述したように、凝縮器４に対向して開口９ｂが形成されているので、凝縮器４に対して開口９ｂより多量の空気を容易に供給することができる。これにより、通風抵抗の大きなクロスフィン形熱交換器を機械室２の凝縮器４として採用しても良好に通風することができる。   Further, as described above, since the opening 9b is formed facing the condenser 4, a larger amount of air can be easily supplied to the condenser 4 than the opening 9b. Thereby, even if it employ | adopts as a condenser 4 of the machine room 2 with a cross fin type heat exchanger with a large ventilation resistance, it can ventilate favorably.

機械室カバー８の通気段部１７，１８を形成する部分には、複数の開口スリット８ａ，８ｂが形成されている。送風機５を運転することにより、この開口スリット８ａを通して冷蔵庫下部の空気及び通気段部１７空間の空気が吸込まれ、開口スリット８ｂを通して機械室２内の暖められた空気が排出される。なお、排出された空気は、通気段部１８の空間を上昇し、冷蔵庫本体１外へと排出される。   A plurality of opening slits 8 a and 8 b are formed in portions where the ventilation step portions 17 and 18 of the machine room cover 8 are formed. By operating the blower 5, the air in the lower part of the refrigerator and the air in the ventilation step portion 17 space are sucked through the opening slit 8a, and the warmed air in the machine room 2 is discharged through the opening slit 8b. The discharged air rises in the space of the ventilation step portion 18 and is discharged outside the refrigerator main body 1.

機械室２に係る空気の流れを説明すると、送風機５の回転により、開口９ｂ及び開口スリット８ａから吸い込まれた空気は、凝縮器４と熱交換された後、送風機５を経て圧縮機６と熱交換され、その後、他方の排出用の開口１０ｂ及び開口スリット８ｂから排出される。   Explaining the flow of air in the machine room 2, the air sucked from the opening 9 b and the opening slit 8 a by the rotation of the blower 5 is heat-exchanged with the condenser 4, passes through the blower 5, and is heated with the compressor 6. After that, it is discharged from the other discharge opening 10b and the opening slit 8b.

また、吸込み用開口９ｂは排出用開口１０ｂと対面する位置関係に設けられているので、熱交換した暖かい空気が機械室カバー８の開口スリット８ｂと共にスムーズに冷蔵庫外へと排出される構成となっている。従って、吸込用開口９ｂから排出用開口１０ｂまでの風路が短く、機械室２内の通風路の圧損が減少するので、送風機５の吸込負荷が軽減し、送風機運転中の出力が低減し、冷蔵庫の消費電力量を抑制することができる。   Further, since the suction opening 9b is provided in a positional relationship facing the discharge opening 10b, the heat exchanged warm air is smoothly discharged to the outside of the refrigerator together with the opening slit 8b of the machine room cover 8. ing. Accordingly, since the air path from the suction opening 9b to the discharge opening 10b is short and the pressure loss of the ventilation path in the machine room 2 is reduced, the suction load of the blower 5 is reduced, and the output during the blower operation is reduced. The power consumption of the refrigerator can be suppressed.

次に、本実施例の冷蔵庫を隣接物に対して狭く遮蔽された状態で据付けた場合における空気の流れについて図７及び図８を参照しながら説明する。図７は図１の冷蔵庫の実据付遮蔽条件での機械室を含む横断面図、図８は図７の機械室部の縦断面図である。なお、図７及び図８における矢印は空気の流れを示す。   Next, the flow of air when the refrigerator according to the present embodiment is installed in a state where the refrigerator is narrowly shielded from adjacent objects will be described with reference to FIGS. 7 and 8. 7 is a cross-sectional view including a machine room under the actual installation shielding condition of the refrigerator of FIG. 1, and FIG. 8 is a vertical cross-sectional view of the machine room part of FIG. In addition, the arrow in FIG.7 and FIG.8 shows the flow of air.

側面板９，１０と隣接物壁面３５，３６との距離Ｌ１は、狭い場合で１０mmぐらいである。実際に据付けられる際には、隣接する壁の下部には、高さＨｈは１００mm、厚さＷｈは１０mm程度の幅木４０があり、飾板の部分と冷蔵庫側面板９，１０は、殆ど隙間の無い状態になる可能性がある。これに対し、開口９ｂ，１０ｂの床面２９からの高さＨ２９を１００mm以上にすることで、飾板によって開口９ｂ，１０ｂが塞がれることが無く、良好に通風することができる。   The distance L1 between the side plates 9 and 10 and the adjacent wall surfaces 35 and 36 is about 10 mm in a narrow case. When actually installed, there is a skirting board 40 with a height Hh of 100 mm and a thickness Wh of about 10 mm at the lower part of the adjacent wall, and there is almost no gap between the decorative plate part and the refrigerator side plates 9 and 10. There is a possibility of becoming a state without. On the other hand, when the height H29 of the openings 9b and 10b from the floor surface 29 is set to 100 mm or more, the openings 9b and 10b are not blocked by the decorative plate and can be ventilated well.

また、冷蔵庫背面の通気段部１７を通して空気が機械室カバー８の開口スリット８ａからも機械室２内に供給される。   Air is also supplied into the machine room 2 from the opening slit 8 a of the machine room cover 8 through the ventilation step 17 on the back of the refrigerator.

そして、冷蔵庫の運転が停止（送風機５が停止）した状態においても、床面空気と機械室２内のドラフト効果で常に新鮮な空気が機械室２内に入り、その後対面する他方の開口１０ｂへ導かれる。従って、この空気によって、凝縮器４及び圧縮機６を冷却することができ、圧縮機６の温度上昇を防止してその信頼性を確保することができる。   And even in the state where the operation of the refrigerator is stopped (the blower 5 is stopped), fresh air always enters the machine room 2 by the draft effect in the floor air and the machine room 2, and then to the other opening 10b facing each other. Led. Therefore, the condenser 4 and the compressor 6 can be cooled by this air, and the temperature of the compressor 6 can be prevented from rising and its reliability can be ensured.

開口１０ｂ側の上述した遮蔽条件での空気流れについて説明すると、機械室２へ送り込まれた空気は、機械室２内の凝縮器４及び圧縮機６等と熱交換した後、開口１０ｂより周囲に暖気となって排出される。排出された暖かい空気は、側面板１０と隣接物壁面３６との隙間Ｌ１を通り、冷蔵庫の側面板１０に沿って上方へと排出される。また、機械室カバー８の開口スリット８ｂからも機械室２内の暖かい空気が同時に排出される。排出された空気は、冷蔵庫背面段部の通気段部１８を上昇し、冷蔵庫外へと排出される。   The air flow under the above-described shielding condition on the opening 10b side will be described. After the air sent into the machine room 2 exchanges heat with the condenser 4 and the compressor 6 in the machine room 2, the air flows to the periphery from the opening 10b. It is discharged as warm air. The discharged warm air passes through the gap L1 between the side plate 10 and the adjacent wall surface 36, and is discharged upward along the side plate 10 of the refrigerator. The warm air in the machine room 2 is also discharged from the opening slit 8b of the machine room cover 8 at the same time. The discharged air rises through the ventilation step 18 on the back of the refrigerator and is discharged outside the refrigerator.

上述した遮蔽条件での冷蔵庫の停止時、即ち送風機５の停止時での空気の流れについて説明すると、ドラフト作用で一方の開口９ｂから空気が吸い込まれ、機械室２内を通って開口１０ｂ，側面隙間Ｌ１の順で排熱通路が形成されて機械室２内の放熱が促進される。   The flow of air when the refrigerator is stopped under the above-described shielding conditions, that is, when the blower 5 is stopped will be described. Air is sucked from one opening 9b by a draft action, passes through the inside of the machine room 2, and the side face 10b. A heat exhaust passage is formed in the order of the gap L1, and heat dissipation in the machine room 2 is promoted.

次に、本実施例の冷蔵庫において開口９ｂ，１０ｂから出てくる圧縮機６の運転音（騒音）について説明する。前述したように開口９ｂ，１０ｂの高さは、圧縮機の中心の高さよりも低い位置に設けている。これによって圧縮機６から発生した運転音が、開口９ｂ，１０ｂを通して冷蔵庫の下方向に抜けるため、冷蔵庫の使用者の耳に直接伝わり難くなり、使用者が感じる騒音レベルを低減することができる。   Next, the operation sound (noise) of the compressor 6 coming out from the openings 9b and 10b in the refrigerator of the present embodiment will be described. As described above, the heights of the openings 9b and 10b are provided at positions lower than the height of the center of the compressor. As a result, the operation sound generated from the compressor 6 passes through the openings 9b and 10b in the downward direction of the refrigerator, so that it is difficult to directly transmit to the refrigerator user's ear, and the noise level felt by the user can be reduced.

更に、前記開口９ｂ，１０ｂにカバー４１を設け、このカバー４１に通気可能にルーバー４１ａを有し、図示例では、ルーバー４１ａの方向は後ろ方向に向けられているが、下方向に向けられていても良い。このルーバー４１ａの方向が下向または後ろ方向に向けられていることにより、圧縮機６から発生した運転音がルーバー４１ａに反射し、音が冷蔵庫の下方向または後ろ方向に行くので、更に冷蔵庫の使用者の耳に直接入り難くなり、使用者の感じる騒音を低減することができる。   Further, a cover 41 is provided in the openings 9b and 10b, and a louver 41a is provided so that the cover 41 can be ventilated. In the illustrated example, the direction of the louver 41a is directed backward, but is directed downward. May be. Since the direction of the louver 41a is directed downward or backward, the operation sound generated from the compressor 6 is reflected on the louver 41a, and the sound goes downward or backward in the refrigerator. It becomes difficult to enter directly into the user's ear, and the noise felt by the user can be reduced.

以上のように、側面板の歪みや風路の突出による外観を損なうことなく機械室側面に開口を設けて機械室への良好な通風を行い、圧縮機及び凝縮器の放熱性能を向上して消費電力の低減を図ることができる。   As mentioned above, the opening on the side of the machine room is provided without impairing the appearance due to the distortion of the side plate or the projection of the air passage, and good ventilation to the machine room is achieved, improving the heat dissipation performance of the compressor and the condenser. The power consumption can be reduced.

また、隣接物壁面との隙間を狭い状態で設置しても機械室側面の開口を通して機械室への良好な通風を行うことができ、圧縮機及び凝縮器の放熱性能を向上して消費電力の低減を図ることができる冷蔵庫を得られる。   In addition, even if it is installed with a narrow gap between adjacent walls, good ventilation can be performed through the opening on the side of the machine room, improving the heat dissipation performance of the compressor and condenser, and reducing power consumption. A refrigerator that can be reduced is obtained.

また、開口を設けたことによる側面板の剛性の低下を免れ、冷蔵庫本体の強度上の信頼性を確保することができる冷蔵庫を得られる。   Moreover, the refrigerator which can avoid the fall of the rigidity of the side plate by having provided the opening and can ensure the reliability on the intensity | strength of a refrigerator main body can be obtained.

また、冷蔵庫の据付寸法を変えず、更に外観を損なうことなく、開口から出てくる圧縮機の騒音を低減することができる冷蔵庫を得られる。   Moreover, the refrigerator which can reduce the noise of the compressor which comes out of an opening is obtained, without changing the installation dimension of a refrigerator and also impairing an external appearance.
