次に、上記した構造の冷蔵庫１において、制御基板ユニット７の上方から冷蔵庫本体３の背面板５に沿って流下する結露水Ｗの流れについて説明する。   Next, the flow of the dew condensation water W flowing down from the upper side of the control board unit 7 along the back plate 5 of the refrigerator body 3 in the refrigerator 1 having the above-described structure will be described.

図４に示すように、制御基板ユニット７の上方の結露水Ｗの大半は、外側結露水Ｗｏとしてカバー部１９の外側面に沿って流れ、冷蔵庫本体３の下部に流下する。その際、結露水Ｗのうちの一部が、内側結露水Ｗｉとしてカバー部１９の内部に流入する場合が想定される。カバー部１９の本体当接面１９ａは冷蔵庫本体３の背面板５に当接しているが、本体当接面１９ａと背面板５との間の僅かの隙間から結露水Ｗの一部がカバー部１９の内部に流入する。   As shown in FIG. 4, most of the dew condensation water W above the control board unit 7 flows along the outer surface of the cover part 19 as the outer dew condensation water Wo and flows down to the lower part of the refrigerator main body 3. In that case, the case where a part of the dew condensation water W flows into the inside of the cover part 19 as the inner dew condensation water Wi is assumed. Although the main body contact surface 19a of the cover part 19 is in contact with the back plate 5 of the refrigerator main body 3, a part of the condensed water W is covered by the slight gap between the main body contact surface 19a and the back plate 5. 19 flows into the interior.

カバー部１９の内部に流入した内側結露水Ｗｉは、上部切欠１７ｄｕ１と背面板５との間の上連通部２３から上部周壁１７ｂｕの上に流下する。上部周壁１７ｂｕ上の内側結露水Ｗｉは、図５中の矢印Ａで示すように上部周壁１７ｂｕに沿って左右両側に分流し、湾曲部１７ｂｐを経て矢印Ｂで示すように左右一対の側部周壁１７ｂｓに沿って下方に向けて流れる。   The inside dew condensation water Wi that has flowed into the cover portion 19 flows down from the upper communication portion 23 between the upper notch 17du1 and the back plate 5 onto the upper peripheral wall 17bu. The inner dew condensation water Wi on the upper peripheral wall 17bu is diverted to the left and right sides along the upper peripheral wall 17bu as shown by the arrow A in FIG. 5, and a pair of left and right side peripheral walls as shown by the arrow B through the curved portion 17bp. It flows downward along 17bs.

矢印Ｂのように流れる内側結露水Ｗｉは、下部外周壁１７ｄｗに流れ落ち、その後、下部切欠１７ｄｗ１と背面板５との間の下連通部２５から、下部外周壁１７ｄｗとカバー部１９との間に流出する。下部外周壁１７ｄｗとカバー部１９との間に流出した内側結露水Ｗｉは、カバー部１９の本体当接面１９ａと背面板５との間の僅かの隙間からカバー部１９の外部に流出する。   The inner dew condensation water Wi flowing as shown by the arrow B flows down to the lower outer peripheral wall 17dw, and then from the lower communication portion 25 between the lower notch 17dw1 and the back plate 5 to between the lower outer peripheral wall 17dw and the cover portion 19. leak. The inside dew condensation water Wi that flows out between the lower outer peripheral wall 17dw and the cover part 19 flows out of the cover part 19 through a slight gap between the main body contact surface 19a of the cover part 19 and the back plate 5.

このように、本実施形態の冷蔵庫１は、カバー部１９の内部に流入した内側結露水Ｗｉが、図５に示すように、ベース部１７の周壁１７ｂと外周壁１７ｄとの間に形成される流路を流れてカバー部１９の外部に流出する。   Thus, in the refrigerator 1 of the present embodiment, the inner condensed water Wi that has flowed into the cover portion 19 is formed between the peripheral wall 17b and the outer peripheral wall 17d of the base portion 17, as shown in FIG. It flows through the flow path and flows out of the cover part 19.

以上説明したように、本実施形態の冷蔵庫１は、冷蔵庫本体３と、冷蔵庫本体３の背面板５に取り付けられる制御基板収容箱１１と、制御基板収容箱１１の内部に収容される制御基板１３と、を有する。制御基板収容箱１１は、制御基板１３を保持して冷蔵庫本体３の背面板５に取り付けられるベース部１７と、制御基板１３を覆うようにしてベース部１７に取り付けられるカバー部１９と、を有する。ベース部１７は、カバー部１９の内部において制御基板１３の上方を覆う上部周壁１７ｂｕを備えている。   As described above, the refrigerator 1 according to the present embodiment includes the refrigerator body 3, the control board storage box 11 attached to the back plate 5 of the refrigerator body 3, and the control board 13 housed inside the control board storage box 11. And having. The control board storage box 11 has a base part 17 that holds the control board 13 and is attached to the back plate 5 of the refrigerator body 3, and a cover part 19 that is attached to the base part 17 so as to cover the control board 13. . The base portion 17 includes an upper peripheral wall 17bu that covers the upper side of the control board 13 inside the cover portion 19.

このため、制御基板ユニット７の上方から冷蔵庫本体３の背面板５に沿って流下する結露水Ｗの一部が、カバー部１９の内部に流入したとしても、上部周壁１７ｂｕによって基板収容領域２１への流入を抑制できる。これにより、基板収容領域２１に収容してある制御基板１３への水の侵入を抑制して制御基板１３を保護することができる。   For this reason, even if a part of the dew condensation water W flowing down from the upper side of the control board unit 7 along the back plate 5 of the refrigerator body 3 flows into the cover part 19, the upper peripheral wall 17 bu enters the board accommodation area 21. Can be suppressed. Thereby, it is possible to protect the control board 13 by suppressing the intrusion of water into the control board 13 housed in the board housing area 21.

本実施形態は、上部周壁１７ｂｕの背面板５から離れたカバー部１９側に、上方に向けて延出する上部端壁１７ｃｕが設けられている。これにより、上部周壁１７ｂｕに流下した内側結露水Ｗｉの基板収容領域２１への流入を、上部端壁１７ｃｕによって抑制できる。上部端壁１７ｃｕは、上部周壁１７ｂｕ上に溜まった内側結露水Ｗｉを堰き止めて基板収容領域２１に流入するのを抑制する。   In the present embodiment, an upper end wall 17 cu extending upward is provided on the cover portion 19 side away from the back plate 5 of the upper peripheral wall 17 bu. Thereby, the inflow to the board | substrate accommodation area | region 21 of the inner side dew condensation water Wi which flowed down to the upper surrounding wall 17bu can be suppressed by the upper end wall 17cu. The upper end wall 17 cu dams up the inner dew condensation water Wi accumulated on the upper peripheral wall 17 bu and suppresses it from flowing into the substrate accommodation region 21.

本実施形態は、上部端壁１７ｃｕの上部から冷蔵庫本体３の背面板５に向けて延出する上部外周壁１７ｄｕを備え、上部外周壁１７ｄｕは、冷蔵庫本体３の背面板５との間に、上部外周壁１７ｄｕの上方と下方とを連通する上連通部２３を備えている。このため、カバー部１９の本体当接面１９ａと冷蔵庫本体３の背面板５との隙間からカバー部１９内に流入した内側結露水Ｗｉは、上連通部２３を通して上部周壁１７ｂｕの上に容易に流下させることができる。   The present embodiment includes an upper outer peripheral wall 17du extending from the upper part of the upper end wall 17cu toward the back plate 5 of the refrigerator main body 3, and the upper outer peripheral wall 17du is between the back plate 5 of the refrigerator main body 3 and An upper communication portion 23 that communicates the upper and lower sides of the upper outer peripheral wall 17du is provided. For this reason, the inside dew condensation water Wi that has flowed into the cover part 19 through the gap between the main body contact surface 19a of the cover part 19 and the back plate 5 of the refrigerator main body 3 easily passes over the upper peripheral wall 17bu through the upper communication part 23. Can flow down.

上連通部２３（上部切欠１７ｄｕ１）よりも左右一対の側部外周壁１７ｄｓ側の上部外周壁１７ｄｕ上に流下した内側結露水Ｗｉは、一部が上連通部２３を通って上部周壁１７ｂｕ上に流下する。上部外周壁１７ｄｕに流下した内側結露水Ｗｉの他の一部は、上連通部２３と反対側のカバー部１９の側部内面に向けて流れる。カバー部１９の側部内面とベース部１７の側部外周壁１７ｄｓとは略接触しているが、当該接触部の隙間に結露水が入り込んでも、そのままカバー部１９とベース部１７との間を下方に流れるだけで、基板収容領域２１に流入することはない。   A portion of the inner dew condensation water Wi that has flowed onto the upper outer peripheral wall 17du on the pair of left and right side outer peripheral walls 17ds from the upper communication portion 23 (upper notch 17du1) passes through the upper communication portion 23 and onto the upper peripheral wall 17bu. Flow down. The other part of the inside dew condensation water Wi that has flowed down to the upper outer peripheral wall 17du flows toward the inner surface of the side portion of the cover portion 19 opposite to the upper communication portion 23. The inner surface of the side portion of the cover portion 19 and the side outer peripheral wall 17ds of the base portion 17 are substantially in contact, but even if condensed water enters the gap between the contact portions, the space between the cover portion 19 and the base portion 17 is not changed. It only flows downward and does not flow into the substrate housing area 21.

本実施形態は、上部端壁１７ｃｕとカバー部１９のベース部当接面１９ｂとは密接している。このため、カバー部１９内に流入した内側結露水Ｗｉが、例え上部端壁１７ｃｕとカバー部１９との当接面に向けて移動したとしても、内側結露水Ｗｉの基板収容領域２１への流入をより確実に抑制できる。   In the present embodiment, the upper end wall 17cu and the base portion contact surface 19b of the cover portion 19 are in intimate contact. For this reason, even if the inner condensed water Wi flowing into the cover part 19 moves toward the contact surface between the upper end wall 17cu and the cover part 19, the inner condensed water Wi flows into the substrate housing area 21. Can be suppressed more reliably.

本実施形態は、ベース部１７が、制御基板１３の側方を覆う一対の側部周壁１７ｂｓを備え、一対の側部周壁１７ｂｓの上端は上部周壁１７ｂｕにつながっている。このため、上部周壁１７ｂｕに流下した内側結露水Ｗｉは、一対の側部周壁１７ｂｓに向けてより効率よく流れる。   In the present embodiment, the base portion 17 includes a pair of side peripheral walls 17bs that cover the sides of the control board 13, and the upper ends of the pair of side peripheral walls 17bs are connected to the upper peripheral wall 17bu. For this reason, the inner dew condensation water Wi that has flowed down to the upper peripheral wall 17bu flows more efficiently toward the pair of side peripheral walls 17bs.

本実施形態は、ベース部１７が、制御基板１３の下方を覆う下部周壁１７ｂｗを備え、一対の側部周壁１７ｂｓの下端は下部周壁１７ｂｗにつながっている。このため、一対の側部周壁１７ｂｓに沿って流下する内側結露水Ｗｉは、下部周壁１７ｂｗに向けてより効率よく流れる。   In the present embodiment, the base portion 17 includes a lower peripheral wall 17bw that covers the lower side of the control board 13, and the lower ends of the pair of side peripheral walls 17bs are connected to the lower peripheral wall 17bw. For this reason, the inner dew condensation water Wi flowing down along the pair of side peripheral walls 17bs flows more efficiently toward the lower peripheral wall 17bw.

本実施形態は、一対の側部周壁１７ｂｓ及び下部周壁１７ｂｗの冷蔵庫本体３の背面板５から離れたカバー部１９側に、側方に向けて延出する一対の側部端壁１７ｃｓ及び下方に向けて延出する下部端壁１７ｃｗがそれぞれ設けられている。側部端壁１７ｃｓ及び下部端壁１７ｃｗの先端から冷蔵庫本体３の背面板５に向けて延出する側部外周壁１７ｄｓ及び下部外周壁１７ｄｗをそれぞれ備えている。下部外周壁１７ｄｗは、冷蔵庫本体３の背面板５との間に、下部外周壁１７ｄｗの上方と下方とを連通する下連通部２５を備えている。   In the present embodiment, the pair of side peripheral walls 17bs and the lower peripheral wall 17bw have a pair of side end walls 17cs extending toward the side and a lower side on the cover 19 side away from the back plate 5 of the refrigerator main body 3. Lower end walls 17cw extending toward each other are provided. A side outer peripheral wall 17ds and a lower outer peripheral wall 17dw extending from the front ends of the side end wall 17cs and the lower end wall 17cw toward the back plate 5 of the refrigerator body 3 are provided. The lower outer peripheral wall 17 dw is provided with a lower communication portion 25 that communicates between the upper and lower sides of the lower outer peripheral wall 17 dw with the back plate 5 of the refrigerator body 3.

これにより、ベース部１７は、周壁１７ｂと外周壁１７ｄとの間に、上連通部２３と下連通部２５とを連通する流路が形成される。当該流路を内側結露水Ｗｉが流れることで、カバー部１９内に流入した内側結露水Ｗｉは、基板収容領域２１への流入が抑制されつつ外部への排出がより効率よくなされる。   As a result, in the base portion 17, a flow path that connects the upper communication portion 23 and the lower communication portion 25 is formed between the peripheral wall 17 b and the outer peripheral wall 17 d. As the inner condensed water Wi flows through the flow path, the inner condensed water Wi that has flowed into the cover portion 19 is more efficiently discharged to the outside while being suppressed from flowing into the substrate housing region 21.
