Description
本発明は、冷蔵庫に関し、特に、冷蔵庫断熱壁内に放熱パイプを設けた冷蔵庫において、放熱パイプの熱が冷蔵庫内へ侵入することを抑制する構造に関する。 The present invention relates to a refrigerator, and more particularly, to a structure in which heat of a heat radiating pipe is prevented from entering the refrigerator in a refrigerator provided with a heat radiating pipe in a refrigerator heat insulating wall.
従来の冷蔵庫としては、冷蔵庫外表面を放熱面として利用した凝縮パイプを設けるとともに、断熱にウレタン等の発泡断熱材と比較して、高い断熱性能を有した真空断熱材を用いた冷蔵庫が提供されている（例えば、特許文献１、２参照）。 As a conventional refrigerator, a condensation pipe using the outer surface of the refrigerator as a heat radiation surface is provided, and a refrigerator using a vacuum heat insulating material having a high heat insulating performance compared to a foam heat insulating material such as urethane is provided for heat insulation. (For example, see Patent Documents 1 and 2).
まず特許文献１で開示された冷蔵庫について説明する。図３は、従来の冷蔵庫の断面図である。図４は、従来の冷蔵庫のＢ−Ｂ断面の内箱の背面近傍の断面図である。図３及び図４において、１は冷蔵庫であり、外箱２と内箱３と、外箱２と内箱３の間に充填した、例えば発泡ウレタンからなる断熱材４とから構成され、前面に開口部５を有した断熱箱体６と、開口部５を閉塞する断熱扉７とにより貯蔵室８を構成している。また、貯蔵室８を冷却するために、冷蔵庫１には、圧縮機（図示せず）、凝縮器（図示せず）、減圧手段（図示せず）、冷却器（図示せず）からなる、例えば炭化水素ガスを冷媒とした冷媒圧縮式冷却システムを備えている。 First, the refrigerator disclosed in Patent Document 1 will be described. FIG. 3 is a cross-sectional view of a conventional refrigerator. FIG. 4 is a cross-sectional view of the vicinity of the back surface of the inner box of the BB cross section of the conventional refrigerator. 3 and 4, reference numeral 1 denotes a refrigerator, which is composed of an outer box 2 and an inner box 3, and a heat insulating material 4 made of foamed urethane, for example, filled between the outer box 2 and the inner box 3. A storage chamber 8 is constituted by a heat insulating box 6 having an opening 5 and a heat insulating door 7 for closing the opening 5. In order to cool the storage chamber 8, the refrigerator 1 includes a compressor (not shown), a condenser (not shown), a decompression means (not shown), and a cooler (not shown). For example, a refrigerant compression cooling system using hydrocarbon gas as a refrigerant is provided.
さらに、外箱２の側面内箱３側に真空断熱材９を貼り付け、断熱性能を向上させるとともに、外箱２表面の発汗を防ぎ、凝縮器の能力を確保するために、凝縮器の一部である凝縮パイプ１０を外箱２の真空断熱材９の外周に金属箔テープなどにより貼り付けている。 Further, a vacuum heat insulating material 9 is attached to the side inner box 3 side of the outer box 2 to improve the heat insulating performance, to prevent sweating on the surface of the outer box 2, and to secure the capacity of the condenser. A condensing pipe 10 is attached to the outer periphery of the vacuum heat insulating material 9 of the outer box 2 with a metal foil tape or the like.
冷蔵庫運転中、圧縮機で圧縮された高温高圧の冷媒ガスは、凝縮器で冷却され、低温、高圧の液冷媒となる。凝縮器を出た液冷媒は、減圧手段で減圧されることにより、低温、低圧の二層流となる。そして冷却器内で貯蔵室８との温度差により液冷媒が蒸発し、蒸発気化熱により、周囲の空気を冷却し、貯蔵室８内を冷却する。 During the operation of the refrigerator, the high-temperature and high-pressure refrigerant gas compressed by the compressor is cooled by the condenser and becomes a low-temperature and high-pressure liquid refrigerant. The liquid refrigerant that has exited the condenser is reduced in pressure by the decompression means to become a low-temperature, low-pressure two-layer flow. Then, the liquid refrigerant evaporates in the cooler due to the temperature difference from the storage chamber 8, the surrounding air is cooled by the heat of vaporization, and the interior of the storage chamber 8 is cooled.
この時、凝縮器の一部である凝縮パイプ１０は高温となり、金属箔テープを介して外箱２と熱伝導することにより、外箱２表面から外気に放熱すると共に、断熱材を介して貯蔵室８内にも放熱する。 At this time, the condensing pipe 10 which is a part of the condenser becomes high temperature, and conducts heat with the outer box 2 through the metal foil tape, thereby radiating heat from the surface of the outer box 2 to the outside air and storing it through the heat insulating material. Heat is also radiated into the chamber 8.
しかしながら、従来の冷蔵庫では、凝縮パイプ１０の真空断熱材９の奥側に位置する部分が貯蔵室８の背面壁よりも奥側に位置するように構成している。 However, the conventional refrigerator is configured such that the portion of the condensation pipe 10 located on the back side of the vacuum heat insulating material 9 is located on the back side of the back wall of the storage chamber 8.
これにより、凝縮パイプ１０の真空断熱材９の奥側に位置する部分と貯蔵室８の距離が長くなる。ここで、凝縮パイプ１０から貯蔵室１８への熱侵入は、凝縮パイプ１０と貯蔵室８の距離が長いほど小さくなるため、貯蔵室８の熱負荷を低減することができる。 Thereby, the distance of the part located in the back | inner side of the vacuum heat insulating material 9 of the condensation pipe 10 and the storage chamber 8 becomes long. Here, the heat intrusion from the condensing pipe 10 into the storage chamber 18 becomes smaller as the distance between the condensing pipe 10 and the storage chamber 8 becomes longer, so that the heat load of the storage chamber 8 can be reduced.
次に、特許文献２で開示された冷蔵庫について説明する。図５は、従来の冷蔵庫の断面図である。図６は従来の冷蔵庫のＣ−Ｃ断面の内箱の上端及び下端を拡大した断面図である。図５及び図６において、１１は凝縮パイプであり、長さを確保して冷却システムの能力を向上させるために略矩形状に蛇行させることにより複数列で構成している。１２は真空断熱材であり、凝縮パイプ１１と重なる部分に溝１３を設けている。 Next, the refrigerator disclosed in Patent Document 2 will be described. FIG. 5 is a cross-sectional view of a conventional refrigerator. FIG. 6 is an enlarged cross-sectional view of the upper and lower ends of the inner box of the CC cross section of the conventional refrigerator. 5 and 6, reference numeral 11 denotes a condensing pipe, which is configured in a plurality of rows by meandering in a substantially rectangular shape in order to ensure the length and improve the capacity of the cooling system. Reference numeral 12 denotes a vacuum heat insulating material, and a groove 13 is provided in a portion overlapping the condensation pipe 11.
これにより、凝縮パイプ１１は高温となるが、真空断熱材１２と重なった部分は断熱性能が高いため、貯蔵室内への熱侵入は抑制される。 Thereby, although the condensation pipe 11 becomes high temperature, since the part which overlapped with the vacuum heat insulating material 12 has high heat insulation performance, the heat | fever penetration | invasion into a storage chamber is suppressed.
しかしながら、特許文献１の構成では、凝縮パイプ１０の長さは断熱箱体６の側面周囲の長さより長くすることができないため、蛇行させた凝縮パイプに対して冷却システムの能力が低くなってしまう恐れがあった。 However, in the configuration of Patent Document 1, the length of the condensing pipe 10 cannot be made longer than the length around the side surface of the heat insulating box 6, so that the cooling system has a low capacity for the meandering condensing pipe. There was a fear.
また、真空断熱材９は通常、グラスウールなどの心材と、それを包む金属箔製の外被材とから構成されているため、真空断熱材の端面に近い部分に熱源となる凝縮パイプ１０があると、金属の熱伝導により熱を真空断熱材９の内箱３側に伝えてしまい、凝縮パイプを真空断熱材と外箱の間に配設した場合に比べ、貯蔵室８への侵入熱が増加する恐れがあった。 Moreover, since the vacuum heat insulating material 9 is normally comprised from core materials, such as glass wool, and the metal-clad outer covering material which wraps it, there exists the condensation pipe 10 used as a heat source in the part near the end surface of a vacuum heat insulating material. Compared with the case where the heat is transferred to the inner box 3 side of the vacuum heat insulating material 9 due to the heat conduction of the metal, and the condensation pipe is disposed between the vacuum heat insulating material and the outer box, the heat entering the storage chamber 8 is less. There was a risk of an increase.
また、凝縮パイプ１０を外箱２の側面に貼り付けるには、貼り付け代が３０ｍｍ程度必要であり、内箱３の背面壁より背面側に凝縮パイプ１０を貼り付けるためには、内箱３の背面壁と外箱２の背面壁の距離を大きく取らなければならず、冷蔵庫の奥行きが大きくなり、使い勝手が悪くなってしまう恐れがあった。 Further, in order to attach the condensing pipe 10 to the side surface of the outer box 2, a pasting allowance of about 30 mm is required. In order to attach the condensing pipe 10 to the back side from the rear wall of the inner box 3, the inner box 3 The distance between the back wall and the back wall of the outer box 2 has to be increased, and the depth of the refrigerator becomes large, and there is a risk that the usability will deteriorate.
これに対して特許文献２の構成では、凝縮パイプ１１の、真空断熱材１２と重なった部分は貯蔵室８内への熱侵入が抑制されるが、真空断熱材１２上下の重なっていない部分は侵入熱が大きくなってしまう。 On the other hand, in the configuration of Patent Document 2, the portion of the condensation pipe 11 that overlaps the vacuum heat insulating material 12 is prevented from entering the storage chamber 8, but the upper and lower portions of the vacuum heat insulating material 12 that are not overlapped are Intrusion heat will increase.
また、冷凍温度帯と冷蔵温度帯の貯蔵室を複数備えている場合は、最上段または最下段の貯蔵室が冷凍温度帯となった場合には、凝縮パイプ１１との温度差が大きくなることにより、侵入熱が大きくなり、効率が低くなってしまう恐れがあった。 In addition, in the case where a plurality of storage rooms for the refrigeration temperature zone and the refrigeration temperature zone are provided, when the uppermost or lowermost storage chamber is in the refrigeration temperature zone, the temperature difference from the condensing pipe 11 becomes large. As a result, the intrusion heat increases and the efficiency may be lowered.
本発明は、上記従来の課題を解決するものであり、凝縮パイプ１１と真空断熱材１２を効率よく配置することにより、冷却システムの能力を向上しつつ、凝縮パイプ１１から貯蔵室８内への侵入熱を低減し、冷却効率が高い冷蔵庫を提供することを目的とする。 The present invention solves the above-described conventional problems, and by efficiently disposing the condensing pipe 11 and the vacuum heat insulating material 12, the capacity of the cooling system is improved and the condensing pipe 11 enters the storage chamber 8. An object is to provide a refrigerator that reduces intrusion heat and has high cooling efficiency.

1 and 2, reference numeral 14 denotes a refrigerating room in a refrigerating temperature zone maintained at a temperature of, for example, about 5 ° C., 15 denotes a refrigerating room in a refrigerating temperature zone kept at a temperature of, for example, about −20 ° C., and 16 denotes, for example, 8 This is a vegetable room in a refrigerated temperature zone maintained at a temperature around ℃. A condensate pipe 17 is formed by meandering in a substantially rectangular shape, and a metal foil is provided on the side of the outer box 2 so that the upper end is above the upper end of the refrigerator compartment 14 and the lower end is below the lower end of the vegetable compartment 16. It is affixed with tape. 18 is a vacuum heat insulating material provided between the condensing pipe 17 and the inner box 3. A groove 19 is provided on the outer box 2 side of the portion overlapping the condensing pipe 17, and the upper end is above the upper end of the refrigerator compartment 14 and the lower end is It is affixed on the outer box 2 so as to be lower than the lower end of the vegetable compartment 16.
そして、凝縮パイプ１７の上端部が真空断熱材１８の上端より上方に配置し、凝縮パイプ１７の下端部が真空断熱材１８の下端より下方に配置している。 And the upper end part of the condensation pipe 17 is arrange | positioned above the upper end of the vacuum heat insulating material 18, and the lower end part of the condensation pipe 17 is arrange | positioned below from the lower end of the vacuum heat insulating material 18.
以上のように構成された冷蔵庫について、以下その動作を説明する。 About the refrigerator comprised as mentioned above, the operation | movement is demonstrated below.
冷蔵庫運転中、高温となった凝縮パイプ１７は、金属箔テープを介して外箱２と熱伝導することにより、外箱２から外気に放熱するとともに、断熱材を介して貯蔵室内へも放熱している。 During the operation of the refrigerator, the condensing pipe 17 that has become hot radiates heat from the outer box 2 to the outside air by conducting heat with the outer box 2 via the metal foil tape, and also radiates heat to the storage room via the heat insulating material. ing.
しかしながら、本実施の形態の冷蔵庫においては、凝縮パイプ１７の真空断熱材１８と重なった部分においては、発泡ウレタンに比べて断熱性能が高いため、従来の冷蔵庫同様貯蔵室内への熱侵入を抑制することができる。 However, in the refrigerator according to the present embodiment, the portion of the condensing pipe 17 that overlaps the vacuum heat insulating material 18 has a higher heat insulating performance than foamed urethane, and thus suppresses heat intrusion into the storage room as in the conventional refrigerator. be able to.
さらに、凝縮パイプ１７と真空断熱材１８を重ねているため、真空断熱材１８端面から外被材を介して熱伝導により内箱３側に熱が伝わらず、貯蔵室内への熱侵入を、より抑制することができる。 Furthermore, since the condensation pipe 17 and the vacuum heat insulating material 18 are overlapped, heat is not transferred from the end face of the vacuum heat insulating material 18 to the inner box 3 side by heat conduction through the jacket material, and heat intrusion into the storage chamber is further prevented. Can be suppressed.
また、真空断熱材１８と重なっていない上下部分は、真空断熱材１８の上端及び下端が、冷蔵室１４の上端よりも上側、野菜室１６の下端よりも下側となっているため、凝縮パイプ１７も冷蔵室１４の上端、野菜室１６の下側となり、冷蔵室１４、野菜室１６と凝縮パイプの距離を長くでき、従来の冷蔵庫同様熱侵入を抑制することができる。 In addition, the upper and lower portions that do not overlap with the vacuum heat insulating material 18 are such that the upper end and the lower end of the vacuum heat insulating material 18 are above the upper end of the refrigerator compartment 14 and below the lower end of the vegetable compartment 16. 17 also becomes the upper end of the refrigerator compartment 14, and the lower side of the vegetable compartment 16, can lengthen the distance between the refrigerator compartment 14, the vegetable compartment 16, and a condensation pipe, and can suppress heat | fever penetration | invasion like the conventional refrigerator.
さらに、上下の貯蔵室を比較的温度の高い冷蔵室１４と野菜室１６とすることにより、凝縮パイプ１７との温度差を小さくできる。凝縮パイプ１７から貯蔵室内への熱侵入は、貯蔵室と凝縮パイプ１７の温度差に比例することから、例えば外気温度を３０℃とした場合、凝縮パイプ１７の温度は３５℃前後となり、上下の貯蔵室を冷凍温度帯の冷凍室とした場合に比べ、熱侵入量を約半分にすることができる。 Furthermore, the temperature difference with the condensation pipe 17 can be made small by making the upper and lower storage rooms into the refrigerator compartment 14 and the vegetable compartment 16 having relatively high temperatures. Since heat intrusion from the condensation pipe 17 into the storage chamber is proportional to the temperature difference between the storage chamber and the condensation pipe 17, for example, when the outside air temperature is 30 ° C., the temperature of the condensation pipe 17 is about 35 ° C. Compared to the case where the storage room is a freezing room in a freezing temperature zone, the heat penetration amount can be reduced to about half.
従って、凝縮パイプ１７から貯蔵室への熱侵入が少ない、効率の高い冷蔵庫とすることができる。 Therefore, it can be set as the highly efficient refrigerator with few heat | fever intrusion from the condensation pipe 17 to a storage room.
また、凝縮パイプ１７の上端部が真空断熱材１８の上端より上方に配置し、凝縮パイプ１７の下端部が真空断熱材１８の下端より下方に配置しているので、真空断熱材１８は凝縮パイプ１７の直線部分のみに溝１９を設けることで配設が可能となり、組み立て工程の簡素化、バラツキを吸収しながら、冷蔵庫の熱負荷をさらに小さくすることができる。 Moreover, since the upper end part of the condensation pipe 17 is arrange | positioned above the upper end of the vacuum heat insulating material 18, and the lower end part of the condensation pipe 17 is arrange | positioned below from the lower end of the vacuum heat insulating material 18, the vacuum heat insulating material 18 is a condensation pipe. By providing the groove 19 only in the 17 straight portions, it becomes possible to dispose, and the heat load of the refrigerator can be further reduced while simplifying the assembling process and absorbing variations.
尚、本実施の形態では、真空断熱材１８を、外箱２に貼り付ける構成としたが、真空断熱材１８を外箱２から浮かせて配設することにより、スペーサーなどの別部材が必要となるが、溝１９を構成することなく同様の効果を得られる。 In addition, in this Embodiment, it was set as the structure which affixes the vacuum heat insulating material 18 to the outer case 2, However, Another member, such as a spacer, is needed by arrange | positioning the vacuum heat insulating material 18 floating from the outer case 2 However, the same effect can be obtained without forming the groove 19.
また、本実施の形態では、冷蔵庫の上を冷蔵室１４、下を野菜室１６として説明したが、例えば上下とも冷蔵室、上が野菜室で下が冷蔵室など、冷蔵庫の上下の貯蔵室を比較的温度の高い貯蔵室とすることにより、同様の効果が得られる。 Further, in the present embodiment, the refrigerator top 14 is described as the refrigerator compartment 14 and the vegetable compartment 16 below the refrigerator. For example, the upper and lower storage compartments of the refrigerator such as the refrigerator compartment at the top and bottom, the vegetable compartment at the top and the refrigerator compartment at the bottom. A similar effect can be obtained by using a storage room having a relatively high temperature.
また、本実施の形態では、外箱２側面に凝縮パイプ１７を貼り付ける仕様として説明したが、例えば外箱２の背面においても同様の構成とすることにより同等の効果が得られる。 Moreover, although this Embodiment demonstrated as a specification which affixes the condensation pipe 17 to the outer case 2 side surface, an equivalent effect is acquired by making it the same structure also in the back surface of the outer case 2, for example.
また、外箱２天面においても同様の構成とすることにより、請求項１から３と同様の効果が得られる。 Moreover, the same effect as that of claims 1 to 3 can be obtained by adopting the same configuration on the top surface of the outer box 2.
本発明は、外箱に凝縮パイプを貼り付けて放熱するとともに真空断熱材により熱侵入を抑制した冷蔵庫であって、凝縮パイプによる貯蔵室への熱侵入を抑制した冷蔵庫を提供することができるので、家庭用及び業務用など様々な種類及び大きさの冷蔵庫等として有用である。 The present invention is a refrigerator in which a condensation pipe is attached to an outer box to dissipate heat and a heat intrusion is suppressed by a vacuum heat insulating material, and a refrigerator in which heat intrusion to a storage room by a condensation pipe is suppressed can be provided. It is useful as refrigerators of various types and sizes for home use and business use.
