201144726 -- --χ- 六、發明說明： 【發明所屬之技術領域】 本發明的實施方式涉及一種冰箱β 【先前技術】 先前’例如在家用冰箱中，為了提高冷藏室内的收納 性’ 一般來說是在冷藏室内設置可卸下的箱内擱板。此時， 為了防止箱内搁板的傾斜或旋轉、又或者是脫落，而從箱 内摘板的左右兩端部突出設置著掛鈎（h〇〇k)，且使所述 掛鈎卡合於對該箱内擱板進行支撐的搁板承接部（例如， 專利文獻1)。 然而，冰箱中，要對冷藏室内進行照明，是將該照明 器設置在頂壁，或設置在内壁，又或者設置在該頂壁及内 壁兩處。作為此種照明器，提出有位於從箱内擱板的前端、 向前方稍微離開的位置處的照明器（例如，專利文獻2)。 在此種構成的照明器中，照明的光難以到達各箱内搁板的 後部’從而有箱内搁板的後方部容易變暗的情況。因此， 考慮通過將照明器設置在箱内擱板的縱深方向上的中央附 近的左右侧壁，而照明所述箱内搁板上表面整體，以實現 目視辨認性的提高。 然而，如果在位於箱内擱板的左右的冷藏室側壁，向 冷藏室的内方突出而設置著照明器等的構造物，則該構造 物與箱内摘板的掛鈎會發生干擾，而擔心出現箱内搁 安裝或卸下變得困難等的問題。 而且，例如在將照明器設置在頂壁的情況下，距照明 4 201144726 上食品載置榈板的角部的位置超出照明器的 照射關’而有容㈣得特別暗的情況發生。

箱3與在該外箱3的内部與外箱3隔開而收容的合成樹脂 製的内箱4之間，發泡填充著例如氨基曱酸乙酯（urethane ) 這樣的發泡隔熱材料而構成。 雖省略詳細說明，但在該隔熱箱體2中還組裝著冷凍 循環（cycle)(未圖示）等。 冰箱1包括：將隔熱箱體2的内部劃分為多個、且前 面具有開口部的多個儲藏室。具體來說，冰箱丨具有：位 於最上部且容積最大的冷藏室5 ;配置於該冷藏室5的下 方的蔬菜室6;配置于蔬菜室6的下方的左側的製冰室7 ; 配置於製冰室7的右側的小冷凍室8;及配置於所述製冰 至7及小冷康室8的下方的冷陳室9。 6 201144726 ^υ-rv/vpii 在各儲藏室的前面，以使這些儲藏室的開口部開閉的 方式而設置著隔熱門，該隔熱門是使例如氨基曱酸酯這樣 的發泡隔熱材料發泡填充於外箱與内箱之間。 具體來說’在冷藏室5的前面的開口部5d設置著：左 右對開式的左門1〇及右門Η，這些左門及右門11分 別利用未圖示的鉸鏈（hinge)、而向左右方向可樞軸轉動。 而且’在左門10的周圍設置著塾圈（gasket) 10a，在 右門11的周圍設置著墊圈Ua。由此，防止冷藏室5内部 的冷氣向外部洩露。 而且’左門1〇的左右方向的寬度尺寸被設定為比右門 11的左右方向的寬度尺寸短。在左門1〇的内側（冷藏室5 側）’以向冷藏室5側突出的方式將左門袋12 (left d〇〇r pocket)在上下方向設置為3段。同樣地，在右門u的内 =(冷藏至5侧），也以向冷藏室5側突出的方式將右門 袋13 (right door pocket)在上下方向設置為3段。 在蔬菜室6、製冰室7、小冷凍室8及冷凍室9的前面， 分別设置著抽出式的門6a、7a、8a、9a。此時，製冰室7 的門7a及小冷;東室8的門8a，在與左門1〇及右門^被 分_位置大致相_左右額的位置處被分割。 另外配置在冰们的下部後方的未圖示的磨縮 機來驅動料冷_環，由此冷㈣冷氣被送至各儲藏 室，以將各儲藏室冷卻。 在冷藏室5内的最下段，配設著用以收納肉或备等的 微來盒14 (chUiedcase)、或收納雞蛋等的小物盒15、用 201144726 以蓄積製冰用的水的供水箱16。 而且，在冷藏室5内，在微凍盒14、小物盒15、供水 箱16的正上方配設著微凍室頂壁板π。 '、 此外’在微冰室頂壁板17的上方設置著—塊固定擱板 18。微凍室頂壁板17及固定擱板18均為玻璃製，以在冷 藏室5内的左侧面與右侧面之間水平狀態地架号的 配置。另外，微凍室頂壁板17及固定擱板也可為^成 樹脂製。 在固定搁板18的上方，以將冷藏室5内上下隔開的方 式，而配置著多段構成箱内搁板的可動搁板，此情況下配 置著2段，即’上段的可動搁板19及下段的可動搁板2〇 (參照圖2)。 由此’冷藏室5内的固定搁板18的上方，被2塊可動 搁板19、20自上開始而隔開為：上段部5a、中段部5b、 下段部5c。 該可動擱板19 (及可動搁板20)由：設置在冷藏室$ 内的左右兩側壁的後方的上段的内箱壓條（bead ) 21 (及 下段的内箱壓條22)、與位於該内箱壓條21 (及内箱壓條 22)的前方而設置的後述的照明單元23 (照明機構）所支 撐（參照圖3)。 該可動搁板19 (及可動搁板20)如圖8所示，例如在 合成樹脂製的框體19a (及可動搁板20a)上，組裝著矩形 狀的玻璃製板19b (及玻璃製板20b)而構成。 如果在可動搁板19 (及可動搁板20)中使用玻璃，則 8 201144726 比起使用合成樹脂的情況重量會增加，隨之會帶來重量威 或南級感。 作為該可動擱板19 (及可動搁板20)的整體，.包括： 將可動搁板19(及可動擱板20)的後方緣部切下而形成的 窄幅部19c (及窄幅部20c);及位於該窄幅部i9e (及窄 幅部20c)的前方、且比所述窄幅部19c (及窄幅部2〇c) 寬的寬幅部19d (及寬幅部20d)。 該窄幅部19c (及窄幅部20c)的左右方向的尺寸，設 定得比設置在冷藏室5内的左右側壁的照明單元23的外蓋 24向冷藏室5的最内方突出的部分之間的距離短（參照圖 3) ’關於照明單元23的詳細情況將於以下進行敍述。 窄幅部19c (及窄幅部20c)的兩侧緣部以支禮於後述 的内粕壓條21 (及内箱壓條22) '而不支樓於設置在照明 單元23的外蓋24的溝部25 (及溝部26)的寬度所構成。 而且，寬幅部19d (及寬幅部20d)的左右方向的尺寸 設定為··比冷藏室5的左右側壁間的距離稍短的尺寸。 其次，對構成載置部的内箱壓條21、2 2進行詳細敍述。 如圖2所示’上段的内箱壓條21以對將冷藏室5内隔開為 上段部5a與中段部5b的上段的可動擱板19進行支撐的方 式，而設置在冷藏室5内的上方。該上段的内箱壓條21 是.為了調整高度而稍離開設置為2段、且該上段的内箱 壓條21包括··上側的内箱壓條2ia與下側的内箱壓條21b。 同樣地，下段的内箱壓條22以對將冷藏室5内隔開為 中段部5b與下段部5c的下段的可動擱板2〇進行支撐的方 201144726 式，在冷藏室5内設置在固定搁板18的上方、且設置在上 段的内箱壓條21的下方。該下段的内箱壓條22也是：為 了調整高度而稍離開設置為2段、且該下段的内箱壓條22 包括：上側的内箱壓條22a與下側的内箱壓條22b。 此處，這些上段的内箱壓條21 (上側的内箱壓條21a 及下侧的内箱壓條21b)、與下段的内箱壓條22 (上側的 内箱壓條22a及下側的内箱壓條22b)的配置以外的構成 為相同，因此，以上侧上段的内箱壓條21a為代表，對具 體的構成進行說明。 内箱壓條21a在冷藏室5的後方的左右兩侧壁（内箱4 的内側側壁），比後述的照明單元23的外蓋24向冷藏室 5的更内方突出而設置著（參照圖3)。 而且’内箱壓條21a的上表面形成為平面、且載置著 可動搁板19,並且下部成為所謂的三角肋（rib)形狀（參 照圖2)。該内箱壓條2la與内箱4形成為一體，且在組 裝前（發泡隔熱材料的填充前），該内箱壓條2ia的内部 成為中空。 而且，在組裝隔熱箱體2時，通過將發泡隔熱材料發 泡填充至該内箱壓條21a的内部為止，而增加構造上的強 度。 而且，内箱壓條21a的縱深方向的尺寸，設定得比從 可動擱板19的前端至冷藏室5的前面的開口部5d的前端 為止的尺寸稍長。這樣的話，即便在將可動搁板19抽出至 冷藏室5的前面的開口部5d前端為止時，可動搁板19後 201144726 · 一·Τ“ 部的左右兩角部也被内箱壓條21a稍微支撐著。 由此，在使用者握住可動搁板19的前端、而使可動搁 板19滑動抽出時，能夠防止因内箱壓條21a對可動搁板 19的支撐突然消失而導致可動擱板19掉落的情況。 因此，即便對於相對較重的玻璃製的可動擱板19，也 可安全地將可動摘板19抽出並取出。 構成照明機構的照明單元23分別設置在所述内箱壓條 21、22的前方、且位於比可動擱板19、2〇的前端緣部更 内側處的左右兩側的側壁，也就是，分別設置在比冷藏室 5内的前後方向的中央稍前方處，且位於可動擱板19、2〇 的左右的左右兩側的側壁（内箱4的内侧側壁）（參昭圖 3)。 …、 δ玄照明單元23由设置在後述的外蓋24的溝部25、26 來對可動搁板19、20進行支撐，並且在内部以跨越所述2 塊可動搁板19、20的方式而具有多個光源。 由此，照明單元23成為對冷藏室5的内部、尤其固定 擱板18及可動擱板19、20的上表面進行照明的構成。 另外，照明單元23為了對作為儲藏室的冷藏室5内部 進行照明，可向固定搁板18及可動擱板19、2〇側照明， 但無需將光源向固定擱板18及可動擱板19、2〇的搁板上 表面傾斜配置。 具體來說，照明單元23如圖4〜圖7所示，整體成為 縱長的矩形狀，在設置著電路基板27的基板安裝構件（即 後板30)上覆蓋支撐部的外蓋24而構成。 201144726 該外蓋24由丙烯酸系（acryl)等的透明或半透明的樹 脂所構成’且以成為比冷藏室5的内側側壁向冷藏室5的 更内方凸出的凸狀的曲線形狀（所謂的拱形形狀）的方式 而突出設置著（參照圖7)。 而且，如圖2所示，在外蓋24上，形成著以與成為載 置部的内箱壓條2卜22的上表面大致相同高度的方式、而 形成為凹溝形狀的上段的可動搁板19用的溝部25 (上側 的溝部25續下侧的溝部25b);以及下段的可動搁板2〇 用的溝部26 (上側的溝部26a與下側的溝部26b )。 可動搁板19、20以可動搁板19、2〇的左右側緣部進 入外蓋24的凹溝形狀的溝部25、26 +，而由此可動摘板 19、20的上下方向的移動被限制的狀態受到支撐。 此時，可動擱板19、20僅分別支撐於内箱壓條2卜22 及外蓋24的溝部25、26,因此能夠沿凹溝形 26滑動而進出。 此處’外蓋24以將溝部25、26載 的保持部一形心 24- 向設置著多個沿左右方向延伸的溝形狀 散部24a的光進行擴散。 使通過該先擴 =光狐部24a下，㈣單元 自才曰向性強的發光二極體等的光源的光被擴散=為= 12 201144726 的面光源’㈣㈣無遺·照日科藏室5内。 另外，該光擴散部24M列如可實施紋理加工，而使來 自光源的光擴散。 電路基板27如圖6所^構成為：在縱長的矩形狀的 塊土板28上女裝著多個光源的發光二極體，並且具 有用以驅動這些發光二極體29的驅動電路（未圖示）。 此時’在基板28上’將3個發光二極體29a、2%、29c 以分別跨越可動嫌19及可_板2Q的方式，也就是， 以分別跨越外Ϊ 24的溝部25及溝部26的方式_己設（參 照圖4)。 由此，在冷藏室5内，對上段部5a、中段部北、下段 ，5C&的空間分別照射來自發光二極體2%、m、29c的光， 從而能夠無遺漏地照明固定擱板18及可動擱板19、2〇的 上表面。 此處，在基板28的左右兩緣部，使左右高度不一致地 設置著多個3字狀的切口部28a 〇 後板30成為縱長的矩形狀、且向冷藏室5的外侧（圖 4中為右侧）凸出的凸狀。而且，後板3〇的上部的背面（内 箱4側）具有平緩的傾斜部3〇a。 在後板30的前表面（冷藏室5内方）、與設置在基板 28的各切口部28a相對應，而朝向冷藏室5内方設置著向 前方上方突出的L字形狀的卡止部3〇b (參照圖6)。 電路基板27通過將形成在基板28的切口部28a卡止 於所述卡止部30b ’而被定位在左右方向及上下方向、且 13 201144726 安裝在後板30上。 而且’在後板30的前表面（冷藏室5内方）的電路基 板27的左右兩側，設置著成為厚壁的保持部3〇c。該保持 部30c上載置著所述外蓋24的溝部25、26。 '、 後板30在保持部30c的背面（内箱4侧）形成著輪轂 部30d ( boss part) ’利用從内箱4的外側（外箱3侧）播 入的固定螺釘32而螺固在内箱4的侧壁。具體來說，在冷 藏至5内的内柏4的左右兩侧的側壁，沿著照明單元23 的後板30的背面形狀'而形成著使内箱4的内側側壁向外 侧凹陷而成的收容部31 (參照圖7)。 照明單元23以後板30部分被收容在收容部31内的形 態而配設著。而且，將固定螺釘32從内箱4的外侧（外箱 3侧）相對於後板30的輪轂部30d而旋入，從而將照明單 元23固定於内箱4。 此情況下，在收容部31的壁面形成著固定螺釘32用 的多個孔33。而且，在後板30上以輪轂部30d為基準而 配置著保持部30c。由此，當將照明單元23的後板30安 裝在收容部31時，以孔33為基準，來決定内箱壓條21(及 22)與保持部30c的相對位置關係。 而且，設置於照明單元23的後板30的電路基板27位 於比可動搁板19、20的左右側緣更外側處，以收容在使内 箱4向外側凹陷而成的收容部μ内的方式而配置，且與冷 藏室5的左右側壁（内箱4的内侧側壁）大致平行地設置 著。 201144726 =卜，外蓋24以下述方式而設置：以對可動擱板i9、 於斑制凹溝形狀的溝部25、26中的最凹陷部、位 匕、令臧室5的左右側壁大致同一面上。 者，本實施方式中’左右的左右對開式的門10、11 L二疋為分別向左右的前方最大打開135度左右。然而， :據設置著冰箱i的相的佈置或傢鱗的佈局的不同， 义時會在冰箱1的左右任—邊、或者兩側，有向冰箱i的 月’J面的前方延伸的牆壁或傢具等。 此時’左右的左右對開式的門10、u會與牆壁或傢具 發生干擾而無法打開到最大打開位置。較理想的是也考 慮到此種狀況，而將配設在冷藏室5内且供使用者操作的 零件（清潔或配置變更等所需的零件），以在至少左右的 門10、11打開90度的狀態下取出至冷藏室5外。 此處，還參照圖9 (a)、圖9 (b)及圖1〇 (a)、圖 1(Kb) ’對在將左右的門打開9〇度的狀態下、將 可動搁板19、20卸下而從冷藏室5内取出的順序進行說 明。另外，由於可動搁板19、20的卸下、取出的順序相同， 因而以可動擱板19為代表進行說明。 在通常的使用狀態（設為第一狀態）下，如圖9 (a) 及圖10 (a)所示，可動擱板19向冷藏室5的内側壓入而 配置著。在該狀態下，可動擱板19的後部的窄幅部19c 的左右兩緣部被支撐於内箱壓條21。而且，可動擱板19 的前部的寬幅部19 d的左右兩緣部被支撐於設置在照明單 元23的外蓋24的溝部25。 15 201144726 -/w-rvv/j-f 裊羹 而且’此時，可動擱板19如圖2所示，可動搁板i9 的上下方向的移動受到溝部25限制。這樣，通過限制可動 摘板19的上下方向的移動，而在可動擱板19被施加了意 外的衝擊的情況下’例如放入内容物的聚對苯二曱酸乙二 醇酯（Polyethylene terephthalate ’ PET)瓶等掉落到可動 擱板19上的情況下’可防止可動擱板19因所述衝擊離開、 而脫離溝部25 ’並可防止由此導致可動擱板19的傾斜或 脫落。 其次’在將可動搁板19從冷藏室5内取出的情況下， 首先’如圖9 (b)所示，在將左右的門1〇、11打開的狀 態（圖9 (a)、圖9 (b)中打開90度的狀態）下，使用 ^利用手來握住可動搁板19的前端，將可動擱板19的前 端向前方滑動而到達冷藏室5的前端的開口部兄的位置為 止’並將可動擱板19抽出（也參照圖10 (b))。 此時’可動擱板19的寬幅部I9d位於溝部25的前方， f為脫離該溝部25的支撐的狀態。也就是，在該狀態下’ 可動搁板19的上下方向的移動未被限制，因而在上下方向 了轉動且成為可將可動搁板19卸下的可却下的狀雜（# 為第二狀態）。 另外在該第一狀態下，可動搁板19的窄幅部i9c的 2兩端部’也就是可動擱板19後部的左右兩角部成為被 内相壓條21的前部稍支撐的狀態。 在該狀態下，為了使可動搁板19向前方滑動，而必缺 要由使用者握住可動搁板19的前端，由於可_板19的 201144726. 後部被支撐著，從而可防止可動搁板19的掉落。 此處，如果想要將可動摘板19從冷藏室5内取出，而 直接從第二狀態向冷藏室5的前端的更前方抽出，則會與 左右的門10、11的門袋12、13發生干擾而無法取出。 對此，在第二狀態下，如圖1〇 (b)的箭頭F所示，使 可動擱板19向前方轉動。而且，通過將可動擱板19避開 左右的門袋12、13而向前方斜下方抽出，則能夠不與門袋 12、13發生干擾地取出。 根據所述本實施方式，可獲得如下的效果。 根據本實施方式的構成，照明單元23位於所述内箱壓 條21、22的前方且比可動擱板19、2〇的前端緣部更内侧 處，且照明單元23設置在冷藏室5内的左右兩側侧壁（内 箱4的内側側壁）。 由此’照明單元23配置在冷藏室5内的前後方向上的 靠中央處，也就是可動擱板19、20的靠中央處，因此甚至 是位於冷藏室5内的後方的可動搁板19、2〇的後部為止， 照明單το 23的光也容易到達，從而能夠無遺漏地照明冷藏 至5内的後部及可動擱板19、2〇的後部為止。 而且’照明單7C 23的外蓋24成為向冷藏室5内方凸 出的凸形狀，且具有凹溝形狀的支撐部25、26而構成。而 且’可動擱板19、20構成為：可動擱板19、2〇的左右兩 側緣部進人該支樓部25、26而被支料，並且上下方向的 移動被限制。 由此’通過限制可動擱板19、20的上下方向的移動， 17 201144726: 例如在放入内容物的PET瓶等掉落到可動搁板Η、2〇上 的情況下、對可動搁板19、2〇施加意外的衝擊的情況，也 可防止可動掷板19、2G離開而脫離切部25、％所導致 的可動搁板19、20的傾斜或脫落。 此外，根據本實施方式的構成，照明單元23以在使内 箱4向外侧凹陷而形成的收容部31内、收納著後板3 形態而設置。 根據該構成，因將照明單元23的一部分收容在收宏 31内，所以能夠確保冷藏室5内的内容積更大。 照明單元23的電路基板27設置成：將作為光源的多 個發光二極體29安裝在一塊基板28上而構成。由此，即 便在為了對冷藏室5内的多個部位（上段部5a、中段部5b、 下丰又部5c)進行照明而安裝多個光源的情況下，也只要一 塊電路基板27即可，從而照明單元23的構成或配線等的 組裝變得簡單。 而且，照明單元23的電路基板27以位於比可動擱板 19、20的左右側緣更外側處、而收容在收容部内的方 式，與冷藏室5的左右侧壁（内箱4的内侧侧壁）大致平 行地設置著。 而且，外蓋24以對可動搁板19、20進行支撐的凹溝 形狀的支撐部25、26中的最凹陷部、位於與冷藏室5的左 右側壁大致同一面上的方式而設置。 由此’能夠將可動搁板19、20的左右方向的尺寸設定 為：與最大冷藏室5的左右側壁間的距離相同的程度，並 18 201144726. 且無需將電路基板27分#!為乡塊，而祖置錢可動摘板 19、20向前方滑動並可取出。 此外，在照明單元23的後板3〇設置著厚壁的載置部 30c’該載置部30c上載置著支撐部25、26。由此，因對 可動搁板19、20進行支撐的支撐部25、26進一步被後板 30的載置部30c所支撐，所以载置於支撐部乃、％的可 動搁板19、20的重量能夠不依賴於支撐部乃、％的強度 而設定。 & 由此，可動擱板19、20可採用雖具有相對重的重量但 权s十性優異的玻璃製的材料，而外蓋24也可採用薄且設計 性優異的材料。 ‘ ° ° 而且，在構成照明單元23的後板3〇上，在厚壁的載 置部30c的者側形成者輪較部3〇d。由此，能夠將固定螺 釘32旋入至輪轂部3〇d’從而可通過螺固而可靠地固定在 收容部31。 而且，在照明單元23的外蓋24内側，在除支樓部25、 26外的部分形成著由沿左右方向延伸的溝形狀等構成的 光擴散部24a。 由此’照明單元23成為使來自指向性強的發光二極體 29的光擴散而更均一的面光源’也能夠無遺漏地廣範圍地 照明至冷藏室5内的後方部為止。 另外，所述實施方式中，照明單元23是經設置在後板 30的輪較部3〇d而螺固於收容部31 ’但並不限於此，例如 也可構成為：代替輪轂部3〇d而在後板30設置凹部（或凸 201144726 ，）’以與該凹部（或凸部）叙合的方式在收容部31的内 箱4的側面設置凸部（或凹部），並通過這些凹凸部來嵌

In this case, two stages, that is, the upper movable shelf 19 are disposed. And the movable shelf 2〇 of the lower stage (refer to Fig. 2). Thereby, above the fixed shelf 18 in the refrigerator compartment 5, the two movable shelves 19 and 20 are separated from the upper side by the upper section 5a, the middle section 5b, and the lower section 5c. The movable shelf 19 (and the movable shelf 20) are: an inner box bead 21 (and an inner box bead 22 of the lower stage) disposed at the rear of the left and right side walls in the refrigerating compartment $, and located therein The illumination unit 23 (illumination mechanism), which will be described later, provided in front of the box bead 21 (and the inner box bead 22) is supported (see FIG. 3). As shown in FIG. 8, the movable shelf 19 (and the movable shelf 20) are assembled with a rectangular glass plate 19b (and a glass plate), for example, on a synthetic resin frame 19a (and a movable shelf 20a). 20b) constitutes. If glass is used in the movable shelf 19 (and the movable shelf 20), 8 201144726 will increase in weight compared to the case of using synthetic resin, which will bring about weight or south sense. As the whole of the movable shelf 19 (and the movable shelf 20), The method includes: a narrow portion 19c (and a narrow portion 20c) formed by cutting a rear edge portion of the movable shelf 19 (and the movable shelf 20); and a narrow portion i9e (and a narrow portion 20c) A wide portion 19d (and a wide portion 20d) that is wider in front and wider than the narrow portion 19c (and the narrow portion 2〇c). The size of the narrow portion 19c (and the narrow portion 20c) in the left-right direction is set to be larger than the innermost portion of the outer cover 24 of the illumination unit 23 provided on the left and right side walls in the refrigerating chamber 5 toward the innermost portion of the refrigerating chamber 5. The distance between them is short (refer to FIG. 3) 'The details of the illumination unit 23 will be described below. Both side edges of the narrow portion 19c (and the narrow portion 20c) are supported by the inner beading strip 21 (and the inner box bead 22) which will be described later, and are not supported by the groove portion 25 provided in the outer cover 24 of the illumination unit 23. (and the groove portion 26) is formed by the width. Further, the size of the wide portion 19d (and the wide portion 20d) in the left-right direction is set to be a size slightly shorter than the distance between the left and right side walls of the refrigerating chamber 5. Next, the inner box bead 21, 2 2 constituting the placing portion will be described in detail. As shown in FIG. 2, the inner tank bead 21 of the upper stage is provided above the refrigerator compartment 5 so as to support the movable shelf 19 which partitions the upper section 5a and the upper section of the middle section 5b in the refrigerator compartment 5. . The inner box bead 21 of the upper section is. In order to adjust the height, the inner box bead 21 of the upper stage is slightly separated from the inner box bead 21 of the upper stage and the inner side bead 21b of the lower side. In the same manner, the inner box bead 22 of the lower stage is supported by a movable type of the movable shelf 2 that partitions the lower portion of the refrigerating chamber 5 into the lower portion 5b and the lower portion 5c, and is fixed in the refrigerating chamber 5 Above the plate 18, it is disposed below the inner box bead 21 of the upper stage. The inner box bead 22 of the lower stage is also slightly spaced apart from the two stages, and the inner box bead 22 of the lower stage includes an inner inner bead 22a on the upper side and an inner inner bead 22b on the lower side. Here, the upper inner bead 21 (the upper inner bead 21a and the lower inner bead 21b) and the lower inner inner bead 22 (the upper inner bead 22a and the lower inner bead 22b) The configuration other than the arrangement is the same.

The circuit board 121 for side illumination is locked to the substrate locking portion 11% by the notch portion 121e formed in the substrate 121a, and is positioned in the left and right direction and the vertical direction and attached to the side illumination mounting member U9. Further, in the front surface of the side illumination mounting member 119, that is, the surface inside the refrigerating chamber 105, as shown in Fig. 26, both edge portions in the width direction of the side illumination mounting member 119 are spanned in the up and down direction, that is, side illumination. In the longitudinal direction of the attachment member 119, a plurality of substrate mounting portions 119f having a small convex shape are provided in the presence of dots. The side lighting circuit board 121 is placed on the board mounting portion n9f. At this time, only a part of the front and rear edge portions of the side illumination circuit board 121 are in contact with the substrate mounting portion 119f. Therefore, it is possible to prevent a circuit failure such as disconnection or short circuit due to contact of the circuit portion with the side illumination mounting member 119. This protects the circuit. In the front surface of the side illumination mounting member 119, as shown in Figs. 25 and 27, a thick-walled holding portion 119c is provided at both outer positions of the side illumination circuit board 121. Further, as shown in FIG. 25, above the holding portion ii9c, side cover claw receiving holes 119d which are rectangular holes are provided corresponding to the side cover claws 120b. » The side cover 120 is as shown in FIG. And the groove portion 120a' corresponding to each of the holding portions 119c is placed, and as shown in FIG. 29, the side cover claws 120b are locked to the corresponding side cover claw receiving holes iBd, thereby illuminating the side mounting member 119. 32 201144726 The size of the side face receiving claw receiving hole 119d in the vertical direction of the side face cover 120, that is, the longitudinal direction is set to be sufficiently long with respect to the size of the side face covering claw 120b. For example, the dimension of the side cover claw receiving hole n9d in the longitudinal direction is set to be at least about twice the size of the side cover claw 12b in the longitudinal direction. The side cover 120 prevents the falling off to the inside of the refrigerating compartment 105 by locking the side cover claws i2〇b to the side cover claw receiving holes 119d. Further, the side cover 120 is restricted in the left-right direction, that is, the width direction of the side cover 12, but the longitudinal direction, that is, the length direction of the side cover 12 is not limited. Therefore, the side cover 120 guides the side cover claws i2〇b to the side cover claw receiving holes 119d so as to be slidable in the up and down direction, that is, the longitudinal direction of the side cover 12〇. In the side mask 120, as shown in Fig. 27, a light diffusing portion 12c is formed on the back surface, that is, the surface facing the side lighting circuit board 121. The light diffusing portion 120c is configured to have a plurality of lattice-like groove shapes, for example, and to diffuse light passing through the light diffusing portion 12c, similarly to the light diffusing portion inb. By the action of the light-diffusion unit 120c, the side-lighting unit 1A8 is a surface light source that diffuses light from a light source such as a light-emitting diode having high directivity and is more uniform, thereby performing the inside of the refrigerator compartment 5 without fail. illumination. The corner portions 1〇9 are provided in the upper left and right corner portions in the refrigerating chamber 105 as shown in Fig. η and Fig. 14 and the like, and the top wall illumination unit 107 is connected to the side illumination unit 1〇8. 33 201144726 That is, the corner masks 1 to 9 constituting the corner portions of the illumination unit 106 are provided at both end portions thereof to be connected to the top wall mask 117 and the side surface cover 12A. Specifically, the corner mask 109 is made of the same material as the top wall mask 117 or the side mask 120, for example, an acrylic-transparent or translucent resin injection-molded article, and as shown in FIG. It is configured to be bent at a substantially right angle along the corner of the inner box 1〇4. The top wall side of the corner mask (10), that is, the portion to which the top wall mask 117 is attached, has a shape similar to the cross-sectional shape along the width direction of the top wall mask 117, that is, the money at the front and rear edges. The shallow dish shape of the rising part. & and the corner mask 109 overlaps the top wall mask 117 as shown in Fig. 26 = again. At this time, the end portion on the top wall side of the thief cover 1G9 and the end portion of the top wall cover 7 are formed in a segment shape in which they are fitted to each other. In particular, as shown in FIGS. 17 and 26, the end portion of the corner mask 1〇9 is provided in such a manner that the portion of the weight 4 is placed on the upper side of the top wall shield 117 and the 'corner mask 109 # The lower surface is located on the same surface as the lower surface of the top wall shield 117 at substantially the same height. Thus, the top wall mask 117 and the corner mask 1〇9 are configured such that the overlapping portions are continuous. Further, in this case, the 'top wall mask m ^ is slid along its length direction' and also the top wall side of the corner mask 1 () 9 is humiliated. The end portion of the first corner side of the corner mask 109, as shown in Fig. 18, is provided with a part of the erected side and the inner side in the front-rear direction, that is, the corner mask 34 201144726, a WTV/V upper/ΑΧ width direction A pair of top wall side locking claws 1〇9& Further, the top wall illuminating attachment member 116 is provided with a pair of top wall side claw receiving portions 116b which are partially formed to descend toward the outer side in the width direction, corresponding to the top wall side locking claws 〇%. The corner cover 109 is attached to the top wall side claw receiving portion 116b by locking the top wall side locking claws 1 〇 9a. As shown in Fig. 26, the top wall illumination mounting member 116 is provided with a locking portion 117c that protrudes downward from a portion in the front-rear direction, that is, in the width direction. The corner mask 109 locks the top wall side locking claws 1〇9a as the movement restricting mechanism to the locking portion 117c, so that the central direction of the refrigerating compartment 1〇5, that is, the center in the longitudinal direction of the top wall lighting unit 107 The movement of the direction is limited. The side surface side of the corner mask 109, that is, the portion connected to the side surface cover 12 is configured to have a shape similar to the cross-sectional shape along the width direction of the side surface cover 12, that is, to the refrigerating chamber 1〇5. The inner side protrudes into a so-called arch shape having a convex curved shape. Further, as shown in Fig. 26, the end portion of the side surface side of the corner mask 109 which is disposed so as to overlap the side mask 1 and the side mask 120 as shown in Fig. 26 has a section 109c and is largely entered to A side locking portion 9d is provided in a manner between the side cover 12A and the side lighting attachment member 119. The front surface of the side surface of the side mask 120 and the side surface of the side surface of the corner mask 1〇9 are formed on substantially the same arcuate surface, and the overlapping portion is smoothly continuous. Further, in this case, the side mask 120 overlaps the side surface side of the corner mask 1〇9 even after the moon movement. 35 201144726 In the upper portion of the sidelight mounting member 119, as shown in Fig. 26, a mask supporting portion is provided so as to protrude inward of the refrigerating chamber 105. The side locking portion 109d of the corner cover 109 is supported by the mask supporting portion u9e, and the segment portion 109c is supported by the upper end of the side cover 120. Further, the 'corner cover 109 is provided to a side surface locking portion 109d as a side surface side movement restricting mechanism, and is provided to the outside of the refrigerating chamber 105, that is, the top wall lighting unit 1 The movement of the outer side in the longitudinal direction of 7 is restricted. The masks of the light-emitting diodes 114b and 114c which are the light sources of the top wall illumination unit 1 〇7 and the light-emitting diodes 121b, 121c and 121d which are the light sources of the side illumination unit 1 〇8 are covered from the inside of the refrigerator compartment 105. It is divided into a top wall mask 117, left and right corner masks 1〇9, and left and right side masks 120, and is continuously provided. Further, as shown in Figs. 15 and 26, the corner mask 109 has a light diffusing portion 10% formed on the back surface, that is, the surface outside the refrigerator compartment 105. Similarly to the light diffusion portion 117b of the top wall cover 117 or the light diffusion portion i2〇c of the side surface cover 120, the light diffusion portion 109b is configured to have a plurality of lattice-like groove shapes and to diffuse through the light. 10% of the light is diffused. The portion of the light irradiated from the light-emitting diodes 114b, 114c of the top wall illumination unit 107 or the light-emitting diodes 121b, 121c, 121d of the side illumination unit 108 is mainly passed through the top wall mask 117 or the side mask 120. Guided to the corner mask 109. 36 201144726 JO'tUUpii Further, the light guided to the corner mask 109 passes through the light diffusing portion 1〇91), is diffused, and is irradiated into the refrigerating chamber 105. Thereby, the corner portion of the upper portion in the refrigerating compartment 1A is also irradiated with light. According to the second embodiment, the following effects can be obtained. According to the configuration of the present embodiment, the illumination unit 106 that illuminates the inside of the refrigerating compartment 1〇5 is connected to the top wall illumination unit 1() 7 provided on the top wall so that the left and right corner masks 1〇9 are connected. The side lighting units 108 on the left and right side walls are continuously provided from the top wall to the left and right side surfaces. According to this configuration, since the illumination unit 1〇6 is continuously provided from the top wall to the left and right side surfaces, “the illumination from both the top wall illumination unit 1〇7 and the side illumination unit is illuminated”, so that even the uppermost food item is contained, for example. It is also difficult to place the position of the corner of the shelf beyond the illumination range of the illumination unit 1〇6. Thereby, the entire interior of the refrigerating compartment 1〇5 can be brightly illuminated. In other words, in the case of a refrigerator, etc., which is accompanied by a change in temperature, such as a refrigerator 1G4 or an illumination unit 1G6, there is a possibility that deformation such as expansion or contraction may occur due to a temperature change. Here, for example, the top wall mask 117, the left and right corner masks 9 = the face mask 20 are made into a body, that is, the inside of the mask which is configured as a part is cooled. ==The force acting in the direction' is thus roughly the same as the contraction force is generated in relation to the installation of the straight hair: r is a big _, also two 37 201144726 Therefore, it is possible to cover the one part A gap is formed between the cover (that is, the top wall shield 117, the left and right corner masks 9, and the left and right side masks 20) and the inner box 104. If such a gap is generated, the design property is of course deteriorated, and foreign matter may enter the gap and adversely affect the lighting circuit boards 114, 121 and the like. However, in the present embodiment, the mask that covers the light source of the illumination unit 106 from the inside of the refrigerating compartment 5 is divided into a top wall mask 117, left and right corner masks 9, and left and right side masks 20. When the inside of the refrigerating compartment 105 is cooled, a contraction force is generated individually for each of the masks, so that it is difficult for the force to function in a direction perpendicular to the top wall or the side surface, that is, in a direction in which the peeling is performed. Especially for the top wall cover 丨 17 and the side cover 120, it is easy to generate a contraction force with respect to the longitudinal direction thereof. In the present embodiment, even if the top wall mask 117, the left and right corner masks 9, and the left and right side masks 12 are shrunk due to the cooling in the refrigerating compartment 105, these masks are difficult to peel off from the inner box 1〇4. . Therefore, it is possible to prevent the occurrence of a gap between the mask and the inner box 1〇4 due to cooling. Further, the 'corner mask 109' is disposed to overlap the top wall mask in and the side cover 12'. According to this configuration, even if the top wall cover 117 and the side cover 20 are contracted, the gap between the corner cover 1〇9 and the top wall cover 117 and the gap between the corner cover 109 and the side cover 120 become large. By overlapping them separately, it is possible to visually see that there is almost no change before and after the contraction. That is, even if the top wall mask U7 or the side mask 120 shrinks due to the cooling in the refrigerating chamber 105, it can be substantially caused by the contraction 38 201144726
WT VV/^/lX 而產生的間隙不會變得明顯，從而可提高設計性。 此處，例如在將頂壁遮罩117完全固定於内箱104的 情況下’如果因冷卻而產生的頂壁遮罩117與内箱1〇4的 變形量的差，也就是頂壁遮罩117與將其加以固定的内箱 104的相對的變形量大，則頂壁遮罩117會被朝向内箱1〇4 拉伸而產生大的應變。 因此，如果使頂壁遮罩117完全固定於内箱1〇4，則會 受到由冷藏至105内的冷卻而帶來的收縮的影響，從而會 發生頂壁遮罩117容易破損的情況。對於侧面遮罩丨2〇而 言也同樣。 然而，本實施方式中，頂壁遮罩117相對於左右方向、 也就是頂壁遮罩117的長度方向可滑動地設置著。同樣 地，側面遮罩120相對於上下方向、也就是側面遮罩12〇 的長度方向可滑動地設置著。 根據該構成’即便在因冷藏室105内的冷卻而導致内 箱104或頂壁遮罩117及側面遮罩210發生收縮，而這此 内箱104與頂壁遮罩117及側面遮罩120之間產生相對的 偏移的情況下，也能夠通過頂壁遮罩117及侧面遮單12〇 沿長度方向滑動而將所述偏移加以吸收。 因此’即便冷藏室105内被冷卻，也可防止頂壁遮軍 1Π及側面遮罩120破損。 而且，這些頂壁遮罩117及侧面遮罩120即便在滑動 後’也分別與角遮罩109重疊。也就是，頂壁遮罩il7及 侧面遮罩120在滑動的前後均與角遮罩109重疊。 39 201144726 、由此，能夠基本上使角遮罩1〇9與頂壁遮罩117的間 隙及角遮罩109與側面遮罩120的間隙不會變得明顯， 從而可進一步提高設計性。 而且，例如内箱104與頂壁照明單元基底115由同系 顏色構成，如果内箱104與頂壁照明單元基底U5發生接 觸’則這些邊界線也難以變得明顯。 然而，例如在因冷卻而導致的收縮等使内箱1〇4與頂 壁照明單元基底115離開的情況下，頂壁照明單元基底115 的陰衫會顯現在關1〇4上，從^這些邊界㈣為黑色的 陰影線而變得明顯。 對此，根據本實施方式，頂壁遮罩117以覆蓋頂壁照 月單元基底115或頂壁照明安裝構件116的大部分的方式 而叹置。同樣地’側面遮罩12〇以覆蓋侧面照明安裝構件 119的大部分的方式而設置。 根據該構成，内箱104與頂壁照明單元基底U5或頂 壁照明安裝構件116、__安裝構件119的邊界線上 所出現的陰影也被頂壁遮罩117或側面遮罩⑽所覆蓋， 因而該陰影不會變㈣顯’從而可確保設計性良好。 而且’角遮罩1G9以向冷藏室1()5的中央方向的移動 被頂壁側卡止爪觀限制、並且向冷藏t 1〇5㈣方的移 動被側面卡止部麵限制的形態，而固定於冷藏室1〇5 的上侧左右的角部。 根據該構成，即便因冷藏室1〇5的冷卻而導致角遮罩 109或内箱104發生變形，角遮罩109的移動也會被限制， 201144726 因此可防止角遮罩109脫離安裝部位。 此外，在冷藏室105的頂壁收容具有發光二極體 114b、114d的頂壁照明用電路基板114，且在左右側面收 容具有發光二極體121b、121c、121d的側面照明用電路基 板 121。 而且，從這些頂壁的發光二極體114b、114c、及側面 的發光二極體121b、121c、121d所照射的光的一部分，被 導引至對光進行導引的光路機構即角遮罩109之後，通過 光擴散部109b後被擴散並照射至冷藏室105内。 由此’因冷藏室105内的上部的角部也被照射光，所 以能夠更有效地對冷藏室1〇5内整體進行照明。 如以上所示，根據本實施方式的冰箱，包括：儲藏室、 及對所述儲藏室内進行照明的照明機構，所述照明機構從 所述儲藏室的頂壁起向左右侧面連續地設置著。根據該構 成’從頂壁及左右侧面均能夠被照明，因此即便是例如最 上段的食品載置擱板的角部的位置也能夠被照得明亮。由 此可將儲藏室内整體照得明亮。 雖…:本發明已以實施例揭露如上’然其並非用以限定 本發月任何所屬技術領域中具有通常知識者，在不脫離 本發月之精神和範圍内，當可作些許之更動與潤飾，故本 ，月之保II圍當視後附之Ψ請專利顧所界定者。 【圖式簡單說明】 干 圖表示第一實施方式的冰箱的概略構成的立體圖。 圖2是表示冷藏室的正面圖。 201144726 圖3是沿著圖2的A-A、線的橫剖平面圖。 圖4是沿著圖3的B_B線的縱剖正面圖。 圖5是透視隔熱箱體而表示的在圖3的箭頭c方向上 所觀察到的側面圖。 圖6是表示在圖3的箭頭D方向上所觀察到的後板的 侧面圖。 圖7是照明單元的橫剖平面圖。 圖8是表示可動擱板的構成的立體圖。 圖9 (a)是可動擱板處於第一狀態的橫剖平面圖，圖 9 (b)是可動擱板處於第二狀態的橫剖平面圖。 圖10 (a)疋可動擱板處於第—狀態的縱剖左側面圖， 圖10 (b\是可動搁板處於第二狀態的縱剖左側面圖。 圖11是表不第二實施方式的冰箱上侧的概略構成的立 體圖。 圖12是表示冷藏室的正面圖。 圖13是透視隔熱箱體而表示照明單元的平面圖。 圖14是沿著圖13的A-A線的縱剖正面圖。 圖15是沿著圖13的B-B線的縱剖正面圖。 圖16是將頂壁遮罩卸下後的狀態的頂壁照明單元的底 面圖。 圖17是沿著圖13的C-C線的縱剖右侧面圖。 圖18是沿著圖13的D-D線的縱剖右侧面圖。 圖19是沿著圖13的E-E線的縱剖右側面圖。 圖20是沿著圖13的F-F線的縱剖右側面圖。 42 201144726 ^ \j I x a 圖21是沿著圖13的G-G線的縱剖右側面圖。 圖22是沿著圖13的H-H線的縱剖右側面圖。 圖23是沿著圖13的I-Ι線的縱剖右側面圖。 圖24是透視隔熱箱體而表示的右侧面圖。 圖25是從冷藏室内方觀察到的將側面遮罩卸下後的狀 態的側面照明單元的圖。 圖26是沿著圖24的J-J線的縱剖正面圖。 圖27是沿著圖24的K-K線的縱剖正面圖。 圖28是沿著圖24的L-L線的橫剖平面圖。 圖29是沿著圖24的M-M線的橫剖平面圖。 圖30是沿著圖24的N-N線的橫剖平面圖。 【主要元件符號說明】 1、 101 :冰箱 2、 102 :隔熱箱體 3、 103 :外箱 4、 104 :内箱 5 :冷藏室(儲藏室） 5a :上段部 5b :中段部 5c :下段部 5d :開口部 6 :蔬菜室 6a、9a :抽出式的門 7 :製冰室 43 201144726 7a :製冰室7的門/抽出式的門 8:小冷凍室 8a :小冷凍室8的門/抽出式的門 9 :冷凍室/左右的角遮罩 10 :左右對開式的左門 10a、1 la :塾圈 11 :左右對開式的右門 12 :左門袋 13 :右門袋 14 :微凍盒 15 :小物盒 16 :供水箱 17 :微凍室頂壁板 18、110 :固定搁板 19 :可動搁板（箱内搁板） 19a :框體 19b :玻璃製板 19c、20c :窄幅部 19d、20d :寬幅部 20 :下段的可動擱板/可動搁板（箱内搁板） 20a :可動搁板 20b :玻璃製板 2卜22 :内箱壓條（載置部） 21a、22a :上側的内箱壓條 201144726 οοπυυριί 21b、22b :下側的内箱壓條 23 :照明單元（照明機構） 24 :外蓋（支撐部） 24a .光擴散部 25、26 :溝部/支撐部 25a、26a :上側的溝部 25b、26b :下側的溝部 27 :電路基板 28、 114a、121a :基板 28a :切口部 29、 29a、29b、29c、114b、114c、121b、121c、121d : 光源（發光二極體） 3 0 ·後板 30a :傾斜部 30b、117c :卡止部 30c :保持部/載置部 30d :輪轂部 31 :收容部 32 :固定螺釘 33 :孔 104a :單元收容部 104b :收容孔 105 :冷藏室 106 :照明單元 45 201144726 jonuupn 107 :頂壁照明單元 108 :側面照明單元 109 :左右的角遮罩 109a :頂壁側卡止爪 109b、117b、120c :光擴散部 109c :段部 109d :側面卡止部 111 :固定搁板支撐部 112 :可動搁板 112a :前搁板 112b :後搁板 113 :可動搁板支撐部 114 :頂壁照明用電路基板 115 :頂壁照明單元基底 115a :基板收容部 115b :矩形狀的安裝孔 116 :頂壁照明安裝構件 116a :基底收容部 116b :頂壁侧爪接收部 116c :頂壁遮罩爪接收部 117 :頂壁遮罩 117a :頂壁遮罩爪 118 :基板安裝構件 118a :基板支撐部 46 201144726 ^οηυυριι 118b :彎曲部 118c :基板用爪 118d :基板載置部 118e :卡止爪 119 :側面照明安裝構件 119a :傾斜部 119b :基板用卡止部 119c :保持部 119d :側面遮罩爪接收孔 119e :遮罩支撐部 119f :基板載置部 120 :側面遮罩 120a :凹溝部 120b :側面遮罩爪 121 :側面照明用電路基板 121e :切口部 122、123 :螺釘 C、D :箭頭 47The gap created by WT VV/^/lX does not become noticeable, which improves design. Here, for example, in the case where the top wall cover 117 is completely fixed to the inner box 104, 'if the difference between the deformation amount of the top wall mask 117 and the inner box 1〇4 due to cooling, that is, the top wall mask 117 is relatively large in the amount of deformation of the inner box 104 to which it is fixed, and the top wall mask 117 is stretched toward the inner box 1〇4 to generate a large strain. Therefore, if the top wall cover 117 is completely fixed to the inner box 1〇4, it will be affected by the contraction caused by the cooling in the refrigerating to 105, and the top wall cover 117 may be easily broken. The same is true for the side cover 丨2〇. However, in the present embodiment, the top wall cover 117 is slidably provided with respect to the left-right direction, that is, the longitudinal direction of the top wall cover 117. Similarly, the side mask 120 is slidably disposed with respect to the up and down direction, that is, the longitudinal direction of the side cover 12?. According to this configuration, even if the inner case 104 or the top wall cover 117 and the side cover 210 are shrunk due to the cooling in the refrigerating compartment 105, the inner case 104 and the top wall cover 117 and the side cover 120 are When a relative offset occurs between the top cover 117 and the side cover 12, the offset can be absorbed by sliding in the longitudinal direction. Therefore, even if the inside of the refrigerating compartment 105 is cooled, it is possible to prevent the top wall from being blocked and the side cover 120 from being damaged. Further, these top wall masks 117 and side masks 120 overlap with the corner masks 109 even after sliding. That is, the top wall mask il7 and the side mask 120 overlap the corner mask 109 both before and after the sliding. 39 201144726 Thereby, the gap between the corner mask 1〇9 and the top wall mask 117 and the gap between the corner mask 109 and the side mask 120 can be substantially made clear, and the design can be further improved. Moreover, for example, the inner box 104 and the top wall lighting unit base 115 are composed of the same color, and if the inner box 104 comes into contact with the top wall lighting unit base U5, these boundary lines are also difficult to become conspicuous. However, for example, in the case where the inner box 1〇4 is separated from the top wall lighting unit base 115 by shrinkage or the like due to cooling, the female shirt of the top wall lighting unit base 115 may appear on the closing 1〇4, from these The boundary (4) becomes obvious as a black hatching. In contrast, according to the present embodiment, the top wall cover 117 is slid in such a manner as to cover most of the top wall illumination unit base 115 or the top wall illumination mounting member 116. Similarly, the side mask 12 is disposed to cover most of the side lighting mounting member 119. According to this configuration, the shadow appearing on the boundary line between the inner box 104 and the top wall lighting unit base U5 or the top wall lighting mounting member 116, the mounting member 119 is also covered by the top wall mask 117 or the side mask (10), and thus This shadow does not change (four) and thus ensures good design. In addition, the movement of the corner cover 1G9 in the center direction of the refrigerating compartment 1 (5) is restricted by the top wall side locking claws, and the movement to the refrigerating compartment 1 (4) is restricted by the side locking portion surface. It is fixed to the left and right corners of the upper side of the refrigerating compartment 1〇5. According to this configuration, even if the corner mask 109 or the inner box 104 is deformed by the cooling of the refrigerating compartment 1〇5, the movement of the corner mask 109 is restricted, and 201144726 can prevent the corner mask 109 from coming off the mounting portion. Further, the top wall illumination circuit board 114 having the light-emitting diodes 114b and 114d is housed in the top wall of the refrigerator compartment 105, and the side illumination circuit board 121 having the light-emitting diodes 121b, 121c, and 121d is housed on the right and left side surfaces. Further, a part of the light irradiated from the light-emitting diodes 114b and 114c of the top wall and the light-emitting diodes 121b, 121c, and 121d on the side surface is guided to an angle mask which is an optical path mechanism for guiding light. After 109, it passes through the light-diffusion part 109b, and is diffused and irradiated into the refrigerator compartment 105. Thereby, since the corner portion of the upper portion in the refrigerating chamber 105 is also irradiated with light, the entire interior of the refrigerating chamber 1A can be more efficiently illuminated. As described above, the refrigerator according to the present embodiment includes a storage compartment and an illumination unit that illuminates the storage compartment, and the illumination mechanism is continuously provided from the top wall of the storage compartment to the left and right side surfaces. According to this configuration, since both the top wall and the left and right side surfaces can be illuminated, the position of the corner portion of the food storage shelf, for example, can be brightened. This makes it possible to brighten the entire storage room. The present invention has been disclosed in the above embodiments, and it is not intended to limit the general knowledge of any of the technical fields of the present invention, and may be modified in some ways without departing from the spirit and scope of the present month. Retouching, so this, the month of the insurance II surrounding the squatting, please ask the patent to define.
