Description

また、冷蔵庫は、貯蔵物を貯蔵するための貯蔵室と、前記貯蔵室の内部と外部とを連通する開口部と、を有する断熱箱体を備える。前記断熱箱体は、前記貯蔵室の壁部を構成する断熱壁を有する。前記断熱壁は、前記断熱箱体の内側を構成する内箱と、前記断熱箱体の外側を構成する外箱と、前記内箱と前記外箱との間に設けられた第１真空断熱パネルと、前記内箱と前記外箱との間において前記第１真空断熱パネルを覆うようにして設けられた第２真空断熱パネルと、を有する。前記第２真空断熱パネルは、板状を折り曲げるようにして形成された屈曲部を有する。前記第１真空断熱パネルは、前記屈曲部を避けた位置に配置されている。 In addition, the refrigerator includes a heat insulation box having a storage room for storing stored items and an opening that communicates the inside and the outside of the storage room. The said heat insulation box has the heat insulation wall which comprises the wall part of the said storage chamber. The heat insulation wall includes an inner box constituting the inside of the heat insulation box, an outer box constituting the outside of the heat insulation box, and a first vacuum heat insulation panel provided between the inner box and the outer box. And a second vacuum heat insulation panel provided so as to cover the first vacuum heat insulation panel between the inner box and the outer box. The second vacuum heat insulation panel has a bent portion formed so as to bend the plate shape. The first vacuum heat insulation panel is disposed at a position avoiding the bent portion.

この場合、第２左側部真空断熱パネル７２は、左溝部７１１内を通る前後２つの放熱パイプ３２のうち、後ろ側の放熱パイプ３２の右側方を覆うようにして設けられている。つまり、第２左側部真空断熱パネル７２は、左溝部７１１内を通る複数の放熱パイプ３２のうち冷凍用冷却器２１に近い放熱パイプ３２の庫内側を覆うようにして設けられている。すなわち、左側部断熱壁４４において、冷凍用冷却器２１に近い放熱パイプ３２に対応する部分は、２枚の真空断熱パネル７１、７２が設けられた２重構造になっている。つまり、放熱パイプ３２と冷凍用冷却器２１との間には、２枚の真空断熱パネル７１、７２が設けられている。このため、左側部断熱壁４４において、冷凍用冷却器２１に近い放熱パイプ３２に対応する部分は、他の部分に比べて断熱性能が高くなっている。したがって、冷凍用冷却器２１は、放熱パイプ３２の放熱による影響をより受け難くなっている。 In this case, the second left side vacuum heat insulation panel 72, of the front and rear two radiating pipe 32 through the left groove 711 is provided so as to cover the right side of the radiating pipe 32 of the rear. That is, the second left side vacuum heat insulating panel 72 is provided so as to cover the inside of the heat radiating pipe 32 close to the refrigeration cooler 21 among the plurality of heat radiating pipes 32 passing through the left groove 711. That is, a portion of the left heat insulating wall 44 corresponding to the heat radiating pipe 32 close to the refrigeration cooler 21 has a double structure in which two vacuum heat insulating panels 71 and 72 are provided. That is, two vacuum heat insulation panels 71 and 72 are provided between the heat radiating pipe 32 and the refrigeration cooler 21. For this reason, in the left side heat insulating wall 44, the portion corresponding to the heat radiating pipe 32 close to the refrigeration cooler 21 has higher heat insulating performance than the other portions. Therefore, the refrigeration cooler 21 is less susceptible to the heat radiation of the heat radiating pipe 32.

ここで、発泡ウレタン４３を右側部断熱壁４５に充填する際、液状の発泡ウレタン４３が、右側部断熱壁４５の後側から前側へ向かって注入される。この場合、図４に示すように、第２右側部真空断熱パネル７４と内箱５０との間の距離は、第２右側部真空断熱パネル７４が設けられていない部分における第１右側部真空断熱パネル７３と内箱５０との間の距離と同等以上に設定されている。そのため、第２右側部真空断熱パネル７４を第１右側部真空断熱パネル７３に設けた構成であっても、第２右側部真空断熱パネル７４が、液状の発泡ウレタン４３の流動を妨げることを抑制し、効率よく発泡ウレタン４３を充填することができる。 Here, when the right side heat insulating wall 45 is filled with the urethane foam 43, the liquid foam urethane 43 is injected from the rear side to the front side of the right side heat insulating wall 45. In this case, as shown in FIG. 4, the distance between the second right side vacuum heat insulation panel 74 and the inner box 50 is the first right side vacuum heat insulation in the portion where the second right side vacuum heat insulation panel 74 is not provided. distance and are set over equal between the panel 7 3 and the inner box 50. Therefore, even if it is the structure which provided the 2nd right side vacuum insulation panel 74 in the 1st right side vacuum insulation panel 73, it suppresses that the 2nd right side vacuum insulation panel 74 prevents the flow of the liquid foaming urethane 43. In addition, the urethane foam 43 can be efficiently filled.

この場合、第２右側部真空断熱パネル７４は、右溝部７３１内を通る前後２つの放熱パイプ３２のうち、後ろ側の放熱パイプ３２の左側方を覆うようにして設けられている。つまり、第２右側部真空断熱パネル７４は、右溝部７３１内を通る複数の放熱パイプ３２のうち冷凍用冷却器２１に近い放熱パイプ３２の庫内側を覆うようにして設けられている。すなわち、右側部断熱壁４５において、冷凍用冷却器２１に近い放熱パイプ３２に対応する部分は、２枚の真空断熱パネル７３、７４が設けられた２重構造になっている。つまり、放熱パイプ３２と冷凍用冷却器２１との間には、２枚の真空断熱パネル７３、７４が設けられている。このため、右側部断熱壁４５において、冷凍用冷却器２１に近い放熱パイプ３２に対応する部分は、他の部分に比べて断熱性能が高くなっている。 In this case, the second right side vacuum heat insulation panel 74, of the front and rear two radiating pipe 32 through the right groove 731 is provided so as to cover the left side of the radiating pipe 32 of the rear. That is, the second right side vacuum heat insulating panel 74 is provided so as to cover the inside of the heat radiating pipe 32 close to the refrigeration cooler 21 among the plurality of heat radiating pipes 32 passing through the right groove portion 731. That is, in the right side heat insulating wall 45, the portion corresponding to the heat radiating pipe 32 close to the refrigeration cooler 21 has a double structure in which two vacuum heat insulating panels 73 and 74 are provided. That is, two vacuum heat insulation panels 73 and 74 are provided between the heat radiating pipe 32 and the refrigeration cooler 21. For this reason, in the right side heat insulation wall 45, the part corresponding to the heat radiating pipe 32 close to the refrigeration cooler 21 has higher heat insulation performance than other parts.

底部７７１は、第１底部真空断熱パネル７６よりも大きく、第１底部真空断熱パネル７６の上方全体を覆っている。この場合、底部７７１は、第１底部真空断熱パネル７６及び、外周部６４５の前側縁部６４６を除く部分に載置されている。そして、底部７７１の下面つまり冷蔵室１１と反対側の面は、第１底部真空断熱パネル７６の上面及び外周部６４５の前側縁部６４６を除く部分の少なくともいずれか一方に、両面テープはホットメルトなどによって接着されている。このように、断熱箱体４０の底部、つまり冷凍室１４の底部は、２枚の真空断熱パネル７６、７７が設けられ、断熱性能が高くなっている。 The bottom 771 is larger than the first bottom vacuum heat insulation panel 76 and covers the entire upper portion of the first bottom vacuum heat insulation panel 76. In this case, the bottom 771 is placed on a portion excluding the first bottom vacuum heat insulating panel 76 and the front edge 646 of the outer peripheral portion 645. The lower surface of the bottom 771, that is, the surface opposite to the refrigerator compartment 11, is at least one of the upper surface of the first bottom vacuum heat insulating panel 76 and the portion excluding the front edge 646 of the outer peripheral portion 645. It is adhered by such as. Thus, the bottom of the insulating box body 40, i.e. the bottom of the freezing chamber 14, two vacuum insulation panel 76,7 7 is provided, the heat insulating performance is high.
