Description

この発明の実施形態は、冷蔵庫に関する。   Embodiments described herein relate generally to a refrigerator.

従来、冷蔵庫の独立した製氷室と隣り合う冷却室を縦方向に仕切る縦仕切部の断熱には、断熱性がやや落ちる発泡スチロールやソフトテープ類の部材が使用されていた。それは射出樹脂成型品である縦仕切部が、独立した構造であったり、上下分割式の構造であったりしていたことから、断熱効果の高いウレタン発泡材を流せない構造となっていた。   Conventionally, a member such as a foamed polystyrene or a soft tape whose heat insulating property is slightly lowered has been used for heat insulation of a vertical partition portion that vertically partitions a cooling chamber adjacent to an independent ice making chamber of a refrigerator. Since the vertical partition which is an injection resin molded product has an independent structure or a vertically divided structure, it has a structure in which a urethane foam material having a high heat insulating effect cannot flow.

このため、縦仕切部には断熱効果の大きいウレタン等の発泡材の使用ができず、樹脂部品を別部材にしたり、他の部材を使用することになり、断熱効果が悪い上にコスト増となったり、部品点数が増えたりしてしまう、という課題があった。   For this reason, it is not possible to use a foaming material such as urethane having a large heat insulating effect for the vertical partition, and the resin part is made a separate member or another member, and the heat insulating effect is poor and the cost increases. There is a problem that the number of parts increases.

仕切部31,32,34の空洞31c,32c,34c、それに下部仕切部33の空洞には、外箱121と内箱122に形成された空洞と連通されている。図7および図8に示すように、これら空洞には、ウレタンを注入して発泡させた発泡ウレタンPUが充填されている。発泡ウレタンPUは、高い断熱性により各仕切部31〜34間の断熱を図ることができる。   The cavities 31 c, 32 c, 34 c of the partition parts 31, 32, 34 and the cavities of the lower partition part 33 communicate with cavities formed in the outer box 121 and the inner box 122. As shown in FIGS. 7 and 8, these cavities are filled with urethane foam PU in which urethane is injected and foamed. The urethane foam PU can achieve heat insulation between the partitions 31 to 34 due to high heat insulation.

各仕切部31〜34の各空洞は、外箱121と内箱122に形成された空洞と連通されている。各仕切部31〜34の発泡ウレタン充填による断熱構造は、外箱121と内箱122の空洞の発泡ウレタン充填による断熱構造と同作業工程により形成される。なお、図6の切欠斜視図での発泡ウレタン充填の図示の状態は省略してある。   Each cavity of each partition part 31-34 is connected with the cavity formed in the outer box 121 and the inner box 122. As shown in FIG. The heat insulation structure by filling with foamed urethane in each of the partition portions 31 to 34 is formed by the same work process as the heat insulation structure by filling with urethane foam in the cavity of the outer box 121 and the inner box 122. In addition, the illustration state of foaming urethane filling in the notch perspective view of FIG. 6 is abbreviate | omitted.

このように、縦仕切部34は、前仕切カバー34aと後仕切カバー34bを前後に分離した状態で形成し、前仕切カバー34aと後仕切カバー34bを合体して構成するようにした。縦仕切部34の空洞34cは、上部仕切部31の空洞31cや中部仕切部32の空洞32cと連結した状態に形成することができる。これにより、空洞34cには、空洞31c,32c等と同じ作業工程で、ウレタンの注入が可能となる。   Thus, the vertical partition 34 is formed in a state where the front partition cover 34a and the rear partition cover 34b are separated in the front-rear direction, and the front partition cover 34a and the rear partition cover 34b are combined and configured. The cavity 34 c of the vertical partition 34 can be formed in a state of being connected to the cavity 31 c of the upper partition 31 and the cavity 32 c of the middle partition 32. As a result, urethane can be injected into the cavity 34c in the same work process as the cavities 31c and 32c.

この実施形態では、製氷室と隣り合う冷凍室を仕切る縦仕切部にも断熱効果の高いウレタン発泡材を充填することができるようにした。これによりウレタン発泡材による断熱効果の向上により、省エネ効果を向上させることが可能となる。   In this embodiment, the urethane foam material having a high heat insulating effect can be filled in the vertical partition that partitions the freezing room adjacent to the ice making room. Thereby, it becomes possible to improve the energy saving effect by improving the heat insulation effect by the urethane foam.

(第2の実施形態)
図9は、第2の実施形態にかかる冷蔵庫について説明するための断面図である。この実施形態は、発泡ウレタン充填時に各仕切部の膨らみを防止するものである。
(Second Embodiment)
FIG. 9 is a cross-sectional view for explaining the refrigerator according to the second embodiment. In this embodiment, each partition portion is prevented from bulging during filling with urethane foam.

すなわち、中部仕切部32の前仕切カバー32a長手方向の内面の上部と底部には、切欠部91が形成された複数のリブ92が一体的に形成されている。後仕切カバー32b長手方向の内面の下部と底部には、切欠部93が形成された複数のリブ94が一体的に形成されている。切欠部91と93には、断面コ字状で長尺の拡がり抑制部材95の対向する係止部951,952が係合されている。   That is, a plurality of ribs 92 each having a notch 91 are integrally formed on the top and bottom of the inner surface of the front partition cover 32a in the longitudinal direction of the middle partition 32. A plurality of ribs 94 each having a notch 93 are integrally formed at the bottom and bottom of the inner surface in the longitudinal direction of the rear partition cover 32b. The notch portions 91 and 93 are engaged with engaging portions 951 and 952 that are opposed to each other with a U-shaped cross-section suppressing member 95 having a U-shaped cross section.

拡がり抑制部材95の係止部951,952が切欠部91,93に係止された場合は、拡がり抑制部材95の作用により、前仕切カバー32aと後仕切カバー32bの間隔は広がらなくなる。この状態でウレタンを注入し、発泡させた場合は、ウレタンの発泡があっても拡がり抑制部材95の作用により、前仕切カバー32aと後仕切カバー32bの膨らみを抑えることができる。   When the locking portions 951 and 952 of the spread suppressing member 95 are locked to the notches 91 and 93, the space between the front partition cover 32a and the rear partition cover 32b does not increase due to the action of the spread suppressing member 95. When urethane is injected and foamed in this state, the expansion of the front partition cover 32a and the rear partition cover 32b can be suppressed by the action of the expansion suppressing member 95 even if urethane is foamed.

この実施形態では、ウレタンが注入される空洞を形成する仕切部が発泡時に膨らむことを防止することができる。これにより、仕切部の膨張による扉の開閉や膨らむことによる商品性の低下を防ぐことが可能となる。   In this embodiment, it can prevent that the partition part which forms the cavity where urethane is inject | poured expands at the time of foaming. Thereby, it becomes possible to prevent the merchantability from deteriorating due to the opening / closing or expansion of the door due to the expansion of the partition portion.

なお、この実施形態では、中部仕切部32を例に挙げた。上部仕切部31、下部仕切部33、縦仕切部34にも同手段を適用することにより、冷蔵庫全体の仕切部の膨らみによる弊害を抑えることができる。   In this embodiment, the middle partition 32 is taken as an example. By applying the same means to the upper partition part 31, the lower partition part 33, and the vertical partition part 34, it is possible to suppress adverse effects caused by the swelling of the partition part of the entire refrigerator.

図9に示す前仕切カバー32aと拡がり抑制部材95は、間隔が開いた状態にある。係止部951,952を切欠部91,93に係止した状態では、前仕切カバー32aと拡がり抑制部材95の間隔を持たない位置関係とする。この場合は、拡がり抑制部材95が切欠部91,93から外れることを防止することができる。   The front partition cover 32a and the spread suppressing member 95 shown in FIG. 9 are in an open state. In a state where the locking portions 951 and 952 are locked to the notches 91 and 93, the positional relationship is such that there is no gap between the front partition cover 32 a and the spread suppressing member 95. In this case, it is possible to prevent the spread suppressing member 95 from being detached from the notches 91 and 93.

また、前仕切カバー32aと拡がり抑制部材95の間隔が図9の状態の場合は、前仕切カバー32aあるいは拡がり抑制部材95の一部が相手方に当接する形状とする。この場合は、拡がり抑制部材95が切欠部91,93から外れることを防止することができる。   Moreover, when the space | interval of the front partition cover 32a and the expansion suppression member 95 is in the state of FIG. 9, it is set as the shape where a part of the front partition cover 32a or the expansion suppression member 95 contacts the other party. In this case, it is possible to prevent the spread suppressing member 95 from being detached from the notches 91 and 93.

(第3の実施形態)
この実施形態は、上部仕切部31、中部仕切部32、縦仕切部34を前後に分割した前仕切カバーと後仕切カバーをそれぞれ一体的にH形状に形成した。前仕切カバーと後仕切カバーを合体すると、上部仕切部31、中部仕切部32、縦仕切部34の各空洞は連通状態となる。この連通の空洞を通してウレタンを注入し発泡させることで断熱構造を実現する。
(Third embodiment)
