冷蔵庫のキャビネットは、内箱と、外箱と、内箱及び外箱の間に形成された断熱空間に設けられた断熱材とから構成されており、断熱空間に設けられた断熱材が厚いほど断熱性能が向上し、冷蔵庫の省電力を図ることができる。 The refrigerator cabinet is composed of an inner box, an outer box, and a heat insulating material provided in a heat insulating space formed between the inner box and the outer box. The thicker the heat insulating material provided in the heat insulating space, the thicker the heat insulating material. The heat insulation performance is improved, and the power saving of the refrigerator can be achieved.

一方、冷蔵庫では、設置スペースに対する内容積の大容量化の要求も高いことから、冷蔵庫のキャビネットの断熱空間の厚さを小さくすることが行われている。その際、断熱空間の厚さを小さくしても断熱性能を充分に確保するため、ウレタンなどの発泡断熱材の一部あるいは全部に換えて断熱性能に優れる真空断熱材を断熱空間に設けている（例えば、下記特許文献１参照）。 On the other hand, in refrigerators, there is a high demand for a large internal volume for the installation space, so the thickness of the heat insulating space of the refrigerator cabinet is being reduced. At that time, in order to secure sufficient heat insulating performance even if the thickness of the heat insulating space is reduced, a vacuum heat insulating material having excellent heat insulating performance is provided in the heat insulating space instead of a part or all of the foam heat insulating material such as urethane. (For example, see Patent Document 1 below).

It is electrically connected to the control board.

この複数のリード線は、キャビネットの断熱空間を通って電気部品と制御基板とを接続しているが、断熱空間には、真空断熱材や、キャビネットに組み込まれる冷凍サイクルの冷媒パイプが設けられている。そのため、断熱空間に配された部材と接触しないように複数のリード線をキャビネットの断熱空間に設ける必要があるが、省電力化のため断熱空間の広範囲に真空断熱材が設けられていることから、リード線を断熱空間に配設しにくい。 These multiple lead wires connect the electric components and the control board through the heat insulating space of the cabinet, and the heat insulating space is provided with the vacuum heat insulating material and the refrigerant pipe of the refrigerating cycle incorporated in the cabinet. There is. Therefore, it is necessary to provide a plurality of lead wires in the heat insulating space of the cabinet so as not to come into contact with the members arranged in the heat insulating space. , It is difficult to arrange the lead wire in the heat insulating space.

The operation of the three-way valve 70 is controlled to control the overall operation of the refrigerator 1.

次に、冷凍サイクル５０の構成について詳述する。冷凍サイクル５０は、図３に示すように、高温高圧のガス状の冷媒を吐出する圧縮機５６の吐出側から順番に、蒸発パイプ６０、凝縮器５８、放熱パイプ６４、防露パイプ６６、ドライヤ６８、および三方弁７０の入口側が接続されている。 Next, the configuration of the refrigeration cycle 50 will be described in detail. As shown in FIG. 3, the refrigeration cycle 50 includes an evaporation pipe 60, a condenser 58, a heat radiation pipe 64, a dew-proof pipe 66, and a dryer in this order from the discharge side of the compressor 56 that discharges a high-temperature and high-pressure gaseous refrigerant. The inlet side of 68 and the three-way valve 70 are connected.

三方弁７０の一方の出口には、減圧手段としての冷蔵キャピラリチューブ７２、冷蔵冷却器５２、冷蔵アキュムレータ７４および冷蔵サクションパイプ７６が、配管により順に接続されている。三方弁７０の他方の出口には、減圧手段としての冷凍キャピラリチューブ７８、冷凍冷却器５４、冷凍アキュムレータ８０、冷凍サクションパイプ８２および逆止弁８４が配管により順に接続されている。そして、逆止弁８４の出口側と冷蔵サクションパイプ７６の出口側が一つになって圧縮機５６の吸入側に接続されている。 A refrigerating capillary tube 72, a refrigerating cooler 52, a refrigerating accumulator 74, and a refrigerating suction pipe 76 as decompression means are sequentially connected to one outlet of the three-way valve 70 by piping. A freezing capillary tube 78, a freezing cooler 54, a freezing accumulator 80, a freezing suction pipe 82, and a check valve 84 as decompression means are connected in order to the other outlet of the three-way valve 70 by piping. The outlet side of the check valve 84 and the outlet side of the refrigerating suction pipe 76 are united and connected to the suction side of the compressor 56.

三方弁７０は、凝縮器５８で液化した冷媒を、冷蔵冷却器５２と冷凍冷却器５４に対して交互に供給するように流路を切り替える切替弁であり、圧縮機５６から凝縮器５８及び冷蔵キャピラリチューブ７２を介して供給される低温の冷媒を冷蔵冷却器５２に供給する冷蔵冷却運転の状態と、冷蔵冷却器５２に供給せずに冷凍冷却器５４に供給する冷凍冷却運転の状態とに、切り替える。 The three-way valve 70 is a switching valve that switches the flow path so that the refrigerant liquefied by the condenser 58 is alternately supplied to the refrigerating cooler 52 and the refrigerating cooler 54. The state of the refrigerating cooling operation in which the low-temperature refrigerant supplied via the capillary tube 72 is supplied to the refrigerating cooler 52 and the state of the refrigerating cooling operation in which the low-temperature refrigerant supplied through the capillary tube 72 is supplied to the refrigerating cooler 54 without being supplied to the refrigerating cooler 52. , Switch.

この冷凍サイクル５０では、冷媒は、圧縮機５６で圧縮されて、高温高圧の気体状の冷媒に変化し、凝縮器５８と放熱パイプ６４と防露パイプ６６で放熱しながら液体状の冷媒となる。液体状の冷媒は、三方弁７０によって冷蔵キャピラリチューブ７２又は冷凍キャピラリチューブ７８に送られ、各キャピラリチューブ７２，７８で気化し易いように減圧され、その後に冷蔵冷却器５２又は冷凍冷却器５４で気化し、周囲から熱を奪うことにより冷気が発生する。周囲から熱を奪った冷媒は、各アキュムレータ７４，８０にそれぞれ流れ、各アキュムレータ７４，８０では気液混合体状の冷媒を気体状の冷媒と液体状の冷媒とにそれぞれ分離し、気体状の冷媒のみが各サクションパイプ７６、８２を経て圧縮機５６へ戻り、再び圧縮され高温高圧の気体状の冷媒となる。 In this refrigeration cycle 50, the refrigerant is compressed by the compressor 56, changed into a high-temperature and high-pressure gaseous refrigerant, and becomes a liquid refrigerant while radiating heat through the condenser 58, the heat dissipation pipe 64, and the dew-proof pipe 66. .. The liquid refrigerant is sent to the refrigerated capillary tube 72 or the refrigerated capillary tube 78 by the three-way valve 70, is depressurized so as to be easily vaporized in each of the capillary tubes 72 and 78, and then in the refrigerated condenser 52 or the refrigerated condenser 54. Cold air is generated by vaporizing and removing heat from the surroundings. The refrigerant that has taken heat from the surroundings flows to each of the accumulators 74 and 80, and each of the accumulators 74 and 80 separates the gas-liquid mixture-like refrigerant into a gaseous refrigerant and a liquid refrigerant, respectively, and makes it gaseous. Only the refrigerant returns to the compressor 56 via the suction pipes 76 and 82 and is compressed again to become a high-temperature and high-pressure gaseous refrigerant.

It enters the heat insulating space 8 and is pulled out to one of the left and right chamfered portions, in this example, the outer surface (insulated space 8 side) of the chamfered portion 6ae connecting the left side plate 6a and the back plate 6e of the inner box 6. The refrigerated pipe body 73 pulled out to the outer surface of the chamfered portion 6ae rises along the chamfered portion 6ae and then extends along the chamfered portion 6ce toward the chamfered portion 6be on the opposite side in the width direction (right side when viewed from the front). Further, it bends downward and descends along the chamfered portion 6be, penetrates the stepped portion 4d-1 of the bottom plate 4d of the outer box 4, and enters the machine room 34. Then, in the machine room 34, the refrigerating capillary tube 72 is connected to one outlet of the three-way valve 70, and the refrigerating suction pipe 76 is connected to the suction side of the compressor 56. Since the inner box 6 is viewed from the back in FIG. 8, the direction of the refrigerating pipe body 73 in the left-right direction is reversed.

また、冷凍サイクル５０の冷凍キャピラリチューブ７８及び冷凍サクションパイプ８２も、冷蔵キャピラリチューブ７２及び冷蔵サクションパイプ７６と同様、ロウ付けなどによって互いに熱交換可能に一体化され冷凍パイプ体７９を構成する（図２参照）。 Further, the refrigerated capillary tube 78 and the refrigerated suction pipe 82 of the refrigerating cycle 50 are also integrated so as to be heat exchangeable with each other by brazing or the like, like the refrigerated capillary tube 72 and the refrigerated suction pipe 76, to form the refrigerated pipe body 79 (FIG. 2).

この冷凍パイプ体７９は、内箱６の内側において背板６ｅに沿わせて設けられた冷凍冷却器５４からキャビネット２の断熱仕切壁２８を形成する内箱６の仕切部６ｆの下面に設けられた導出孔６ｆ−１を通って断熱仕切壁２８内に進入する。 The refrigerating pipe body 79 is provided on the lower surface of the partition portion 6f of the inner box 6 forming the heat insulating partition wall 28 of the cabinet 2 from the refrigerating cooler 54 provided along the back plate 6e inside the inner box 6. It enters the heat insulating partition wall 28 through the lead-out hole 6f-1.

導出孔６ｆ−１から断熱仕切壁２８内に進入した冷凍パイプ体７９は、断熱仕切壁２８において冷凍温度帯の貯蔵室に近接する側（この例では断熱仕切壁２８の下側）を通って
上記した冷蔵パイプ体７３が引き出された左右一方の面取り部と反対側の面取り部、この例では、内箱６の右側板６ｂ及び背板６ｅを連結する面取り部６ｂｅの外面まで引き出される。面取り部６ｂｅに引き出された冷凍パイプ体７９は、上方に向けて折り曲げられ面取り部６ｂｅの外面に沿って上昇し、当該面取り部６ｂｅの上端部において下方に折り曲げられる。その際、当該面取り部６ｂｅの上端部では、冷凍パイプ体７９が冷蔵庫幅方向外側から内側に向かって折り曲げられている。これにより、冷凍パイプ体７９が有する冷凍サクションパイプ８２において冷凍冷却器５４に近接する上流側冷凍サクションパイプ８２ａが、これより下流側（圧縮機５６側）に位置する下流側冷凍サクションパイプ８２ｂより冷蔵庫幅方向外側に配置されている。そして、このように面取り部６ｂｅの外面に沿って設けられた冷凍パイプ体７９は、外箱４の底板４ｄの段差部４ｄ−１を貫通して機械室３４へ進入する。 The refrigerating pipe body 79 that has entered the heat insulating partition wall 28 from the lead-out hole 6f-1 passes through the side of the heat insulating partition wall 28 that is close to the storage chamber in the refrigerating temperature zone (in this example, the lower side of the heat insulating partition wall 28). The refrigerated pipe body 73 is pulled out to the chamfered portion on the opposite side of the left and right chamfered portions, and in this example, to the outer surface of the chamfered portion 6be connecting the right side plate 6b and the back plate 6e of the inner box 6. The freezing pipe body 79 pulled out to the chamfered portion 6be is bent upward, rises along the outer surface of the chamfered portion 6be, and is bent downward at the upper end portion of the chamfered portion 6be. At that time, at the upper end of the chamfered portion 6be, the refrigerating pipe body 79 is bent from the outside to the inside in the width direction of the refrigerator. As a result, in the freezing suction pipe 82 of the freezing pipe body 79, the upstream freezing suction pipe 82a close to the freezing cooler 54 becomes a refrigerator from the downstream freezing suction pipe 82b located on the downstream side (compressor 56 side). It is arranged on the outside in the width direction. Then, the refrigerating pipe body 79 provided along the outer surface of the chamfered portion 6be penetrates the stepped portion 4d-1 of the bottom plate 4d of the outer box 4 and enters the machine room 34.

なお、冷蔵パイプ体７３が有する冷蔵サクションパイプ７６や、冷凍パイプ体７９が有する冷凍サクションパイプ８２は、キャビネット２の左側壁２ａや右側壁２ｂや背壁２ｅに設けられた真空断熱材７ａ、７ｂ、７ｅから離して断熱空間８に配置することが好ましい。このように冷蔵サクションパイプ７６や冷凍サクションパイプ８２が真空断熱材７ａ、７ｂ、７ｅに接触しないように配置することで、冷蔵サクションパイプ７６や冷凍サクションパイプ８２の冷熱が、真空断熱材７ａ、７ｂ、７ｅの外皮を構成する金属膜層を介して真空断熱材７ａ、７ｂ、７ｅに接触する外箱４に伝導しにくくなり、外箱４表面における結露の発生を抑えることができる。 The refrigerated suction pipe 76 included in the refrigerated pipe body 73 and the refrigerated suction pipe 82 included in the refrigerated pipe body 79 are the vacuum heat insulating materials 7a and 7b provided on the left side wall 2a, the right side wall 2b and the back wall 2e of the cabinet 2. , 7e and preferably arranged in the heat insulating space 8. By arranging the refrigerated suction pipe 76 and the refrigerated suction pipe 82 so as not to come into contact with the vacuum heat insulating materials 7a, 7b and 7e, the cold heat of the refrigerated suction pipe 76 and the refrigerated suction pipe 82 can be transferred to the vacuum heat insulating materials 7a and 7b. , It becomes difficult to conduct to the outer box 4 in contact with the vacuum heat insulating materials 7a, 7b, 7e through the metal film layer constituting the outer skin of 7e, and the occurrence of dew condensation on the surface of the outer box 4 can be suppressed.

冷蔵水受部３１に接続された冷蔵排水ホース３３は、図８に示すように、背板６ｅにおいて導出孔６ｅ−１の下方に設けられた導出孔６ｅ−２を通って断熱空間８内に進入し、冷蔵パイプ体７３が引き出された左右一方の面取り部６ａｅ（つまり、冷凍パイプ体７９が引き出された左右他方の面取り部６ｂｅと反対側の面取り部６ａｅ）の外面まで引き出される。面取り部６ａｅの外面に引き出された冷蔵パイプ体７３は、面取り部６ａｅに沿って下降し、外箱４の底板４ｄの段差部４ｄ−１を貫通して機械室３４へ進入する。 As shown in FIG. 8, the refrigerated drain hose 33 connected to the refrigerated water receiving portion 31 passes through the outlet hole 6e-2 provided below the outlet hole 6e-1 in the back plate 6e and enters the heat insulating space 8. It enters and is pulled out to the outer surface of one of the left and right chamfered portions 6ae from which the refrigerated pipe body 73 is pulled out (that is, the chamfered portion 6ae on the opposite side of the left and right other chamfered portion 6be from which the refrigerated pipe body 79 is pulled out). The refrigerated pipe body 73 pulled out to the outer surface of the chamfered portion 6ae descends along the chamfered portion 6ae, penetrates the stepped portion 4d-1 of the bottom plate 4d of the outer box 4, and enters the machine room 34.
