201122393 六、發明說明: 【發明所屬之技術領域:j 發明領域 本發明係有關於一種提高防止作為冷凍循環系統内之 冷凍機油之油從壓縮機流出之性能的冰箱。 C先前技 發明背景 近年來,從地球環境保護之觀點,冰箱朝更省能源化 發展,且要求提高其使用性及收納性。 習知此種冰箱採用將形成機械室之壓縮機等設置於使 用便利性差之冰箱本體頂面或冰箱本體背面上部。此習知 之方法揭示於日本專利公開公報平11-183014號。 第18圖顯示日本專利公開公報平11-183014號所記載 之習知冰箱結構。 冰箱本體1由從上開始為冷藏室2、蔬菜室3及冷凍室4 之結構構成,冷藏室2具有旋轉門5,蔬菜室3具有蔬菜室拉 出門6,冷凍室4具有冷凍室拉出門7。在此結構中,由冰箱 内風扇8及蒸發器9構成之冷卻單元10以與形成收納部作為 最下段儲藏室之冷凍室4開口部的高度尺寸大致相同之高 度設置於冷凍室4之背面後部。壓縮機11設置於使用便利性 差之冰箱2頂面或設在冰箱本體1背面上部之凹部12。 壓縮機11之收納體積藉從區隔冷藏室2與蔬菜室3之區 隔壁下側移動至上側,而使各儲藏室之内容積一定時,冷 藏室2與蔬菜室3之區隔壁位置必定下降至下方,而可輕易 201122393 取出蔬菜室3内之收納物。 然而,在習知之結構中,藉將蒸發器配設於冰箱本體 之底面附近,而將與壓縮機連接之吸入配管(圖中未示)與蒸 發器配置於壓縮機下方°因而’在客戶從原來配送至店面 之物流的冰箱運送或移設中’便有以下問題,即,當使冰 箱橫倒而進行搬運時’冷束機油從壓縮機(以下稱為油)逆 流,而於設置後,仍滯留於下方。 當油逆流而流出時’壓縮機内部之油量減少。吸入配 管為減低壓力損失’而設計大尺寸6.35mm至7.94mm左右之 外徑,假設管厚度為5mm ’長度為2000mm時’内容積 為50ml至80ml。由於吸入配管長度限定進行毛細管與吸入 配管之熱交換之長度’故為進行高效率化’無法使吸入配 管之長度縮短。且’當增加蒸發器内之配管容積時’會成 為極大之容積。再者’為減低壓力損失,當進行吸入配管 之大徑化時,配管内容積便越大。 另一方面,有關壓縮機之油儲藏量’由於為配置於頂 面,而可有效地使冰箱之頂面之無效容積小型化至小型形 狀,然而,一旦為小型,油儲藏量之變動而使油面高度變 化之影響便增大。簡單說明,當令壓縮機底面為140mni與 100mm之四角柱形狀,且使内部收納零件之谷積為空時, 以14ml之油量變動’使1 mm之油面南度產生變化。即使僅 之前之50ml至80ml流出,仍減少3.5mm至5.7mm之油面高 度。實際上,由於有内部收納物之容積,且油面高度愈高, 則收納物容積愈大,而產生更多之油面高度之減少。 4 201122393 然而,由於壓縮機11利用差壓或離心力將儲存於内部 下方之油供給至滑動部,故因油面高度減少,而使滑動部 之油供給量減少,而使滑動部摩損等。 又,配管中之油於進行冷卻運轉時,與冷媒循環緩慢 地回至壓縮機,故黏度高之油一旦流出時,則不易即刻與 重力抗衝而回至壓縮機。 【發明内容】 發明揭示 本發明之冰箱包含有隔熱箱體、冷;東循環系統、油、

種具有防止油從壓縮機流出,且將壓縮機配設於蒸發器上 方之冷凍循環系統之冰箱。 本發明之冰箱除了將壓縮機配置於冰箱頂面外,並防 止冰箱橫倒時,油流出至配置於下方之吸入配管及蒸發器等 故可確保壓縮機内之油量,而防止油面高度大幅減少,而 確保對壓縮機滑動部之油的供給,可進一步減底壓縮機之 損傷等。 本發明之冰箱包含有隔熱箱體,依序具有設於前述隔 熱箱體之壓縮機、冷凝器、減壓器與蒸發器而形成一連串 之冷媒流路的冷凍循環系統及封入壓縮機之油。壓縮機為 内部低壓型,且配設於隔熱箱體之頂面部,蒸發器設置於 壓縮機下方。於連接前述壓縮機與前述蒸發器之吸入配管 設置防止油從前述壓縮機内部流出至前述蒸發器側之防止 油流出陕。 201122393 在客戶原本從配送至店家之物流的冰箱運送或移設 中,當使冰箱橫倒而進行搬運時,壓縮機亦橫倒,而使油 流入壓縮機内部開放之吸入配管之開口端。然而,由於於 本發明之吸入配管設置防止油流出阱,故油不致流出至吸 入配管内深部,且油不致從吸入配管逆流流出至蒸發器。 藉此,在搬運等後,即使使冰箱直立設置,亦可藉防止油 流出阱,防止油滯留於較壓縮機位於下方之吸入配管及蒸 發器。 因而,藉由將壓縮機配置於冰箱頂面,可於冰箱橫倒 時防止油流出至配置於壓縮機下方之吸入配管及蒸發器 等,故可確保壓縮機内之油量,而防止油面高度大幅減少, 而確保對壓縮機滑動部之油的供給,可進一步減低壓縮機 之損傷等。 又,由於可使吸入配管之内容積增大,故可從因内徑 擴大造成之低壓力損失化及使配管長度延長,使與毛細管 之熱交換長度增加造成之冷凍效果擴大,謀求省能源化。 又,本發明之冰箱中,前述隔熱箱體於頂面後方具有 凹部,前述凹部設有壓縮機及防止油流出阱。 藉此,在冰箱之搬運或移設中,使冰箱橫倒而進行搬 運時,於壓縮機之傾斜增大之頂面後方部設有壓縮機時, 藉防止油流出阱,可防止油滯留於位於壓縮機下方之吸入 配管及蒸發器。 又,本發明之冰箱中,前述防止油流出阱傾斜而使前 述隔熱箱體之前面側朝上時,可防止油從前述壓縮機内部 8 201122393 流出至前述蒸發器側。 藉此’於橫倒成使冰箱前面之門朝上之搬運或移設 時,亦可防止油從壓縮機流出。 又’本發明之冰箱中,前述防止油流出阱具有於前述 隔熱箱體之前後方向使前述配管彎曲成u字形之u形彎曲 部,至少前述彎曲部之一部份配置成較壓縮機之中心線, 靠近前述隔熱箱體前方側,且至少吸入配管之一部份配置 成較壓縮機之中心線,靠近隔熱箱體之前方側。 當冰箱前面之門面向橫向或下方時,門便自然開啟, 而對搬運者不安全,為防止冰箱内零件或收納物落下等問 題,常有使用設置於冰箱背面與底面之冰箱把手,進行冰 箱搬運或移設。於進行此冰箱搬運或移設時,可防止冰箱 橫倒成前面之門朝上時,油從壓縮機流出。 即,當壓縮機如此橫倒時,設於吸入配管之隔熱箱體 刖後方向之防止油流出阱會成為上下方向之配管阱。因 而,即使油流入壓縮機内部開放之吸入配管之開口端,至 少以從壓縮機中心、設置至上方之吸人配管巧料曲部防 止油流出。 再者,配管U形彎曲部可作為彈性部,緩和振動。 又,本發明之冰箱將設於吸入配管之防止油流出啡設 於壓縮機殼體内部。藉此,當使冰箱橫倒進行搬運時,= 防止油之逆流流出,且刪減設置壓縮機之隔熱箱體凹部之 配管收納而謂賴冰㈣容積增加或隔熱壁厚度 增加造成之魏源化。再者,於設於壓縮機㈣之冷媒= 201122393 入路徑,而用以消音之消音器直接連接吸入配管,而構成 以消音器作為防止油流出阱時,不致吸入因壓縮機構成零 件之熱影響而變熱之冷媒氣體,而從吸入配管直接吸入冷 媒氣體,可提高效率,達成省能源化。 又,本發明之冰箱中,設於吸入配管之前述防止油流 出阱為一室,其係使前述蒸發器之連接側從上方突出至内 部,而從下方連接前述壓縮機連接側者。如此,不需配管 彎曲所需之空間,即可形成配管阱,亦不致妨礙平常運轉 時之油之返回。 又,本發明之冰箱中,設於吸入配管之防止油流出阱 將壓縮機與吸入配管之連接部配置成較壓縮機之中心線, 靠近隔熱箱體前方。如此,使用設置於冰箱背面或底面之 冰箱把手,進行使冰箱橫倒成前面門朝上之搬運或移設 時,可防止油從壓縮機流出。 即,當壓縮機如此橫倒時,吸入配管之連接部位於壓 縮機中心上方。因而,由於於壓縮機内部開放之吸入配管 之開口端位於油面上方,可防止油流出。 又,本發明之冰箱之内部低壓型之壓縮機具有上下分 割之上殼體及下殼體。於内部收納構成零件後,上殼體與 下殼體在殼體接合部密閉接合,且在設於下殼體側之吸入 配管,從殼體接合部至上方配置配管直立部。如此,可使 壓縮機高度小型化,同時,可以配管直立部解決對油面高 度之變動幅度之降低,故可使隔熱箱體之凹部小容量化, 而可謀求内容積之擴大與在冷藏室内突出之小型化。 10 201122393 又,本發明之冰箱中,内部低壓型之壓縮機設有内部 構成零件傾斜防止機構。如此,於冰箱搬運移設時’即使 橫倒而使壓縮機傾斜,仍可防止内部構成零件之傾斜’而 防止壓迫移動至傾斜侧之冷凍機油之容積,可確保空間 部,故可防止冷凍機油易從吸入配管流出之情況。 又,本發明之冰箱中,内部低壓型之壓縮機具有上下 分割之上殼體及下殼體。於内部收納構成零件後,上殼體 與下殼體在殼體接合部密閉接合,設置於下殼體側之吸入 配管在與下殼體内壁面大致同一面上於壓縮機内部開口。 在具有壓縮機傾斜時,油更易從吸入配管流出之吸入配管 的壓縮機中,於搬運等後,即使使冰箱直立設置,亦可防 止油滯留於位於壓縮機下方之吸入配管及蒸發器。 又’本發明之冰箱於前述冷洗循環系統封入冷媒。前 述冷媒為在液化之狀態下,較前述油比重輕者。在使用壓 縮機傾斜時,油更易從吸入配管流出之冷媒與油之組合的 壓縮機中,於搬運等後,即使使冰箱直立設置,亦可防止 油滯留於位於壓縮機下方之吸入配管及蒸發器。 又,本發明之冰箱中’封人冷;東循環系統之冷媒為 R600a,且封人壓縮機之油為礦物油。如此,由於冷媒之每 單位時間之體積《增A,故冷_過冷衫制時之配 管内流速較R134a增大2倍,較c〇2增大⑽倍1此可 使滯留於冷H统内之油迅速回至壓縮機内部而可防止 殼體内之油量不足。 又,本發明之冰箱中,以電動元件作為於旋轉子使用 201122393 永久磁鐵之變流電動機,且壓縮元件之軸承部嵌插於前述 電動元件之旋轉子的高度範圍内,藉此,可以支撐由電動 元件及壓縮元件構成之内部構成零件之部份以外的構成元 件,謀求高度方向之小型化。 藉此,不以支撐壓縮元件及電動元件之支撐部作為高 度減低之元件,而可以壓縮元件及電動元件謀求高度減 低,藉此,油不與支撐部以外之内部構成零件緩衝,而使 油面高度之變動不易產生,而可抑制油從吸入配管流出。 又,本發明之冰箱係包含有於頂面後方設有凹部之隔 熱箱體、配設於前述凹部之内部高壓型壓縮機及設置於前 述隔熱箱體頂面部之冷凝器,前述壓縮機與前述冷凝器藉 吐出配管連接,前述冷凝器配置成較前述壓縮機之吐出配 管連接部,靠近前述隔熱箱體之前方且高之位置。 藉此,使冰箱橫倒時,壓縮機亦橫倒,油流入壓縮機 内部開放之吐出配管之開口端,而使油不致因自身重量向 直接連接之冷凝器流出。可防止當流出許多油至冷凝器 時,由於冷凝配管或其下流之毛細管油堵塞而妨礙冷媒之 循環,而對性能明顯降低或信賴性惡化造成影響。 又,藉由將壓縮機配置於冰箱頂面,可於冰箱橫倒時 防止油流出至配置於下方之吸入配管及蒸發器等,故可確 保壓縮機内之油量,而防止油面高度大幅減少,確保對壓 縮機滑動部之油的供給,可進一步減低壓縮機之損傷等。 以下,一面參照圖式,一面就本發明實施形態作說明。 另,不以該等實施形態限定本發明。 12 201122393 (第1實施形態) 第1圖係本發明第1實施形態之冰箱之概略截面圖,第2 圖係同一實施形態之冰箱之概略背面圖,第3圖係同一實施 形態之冰箱之概略零件展開圖,第4圖係同一實施形態之冰 箱之吸入配管主要部份概略立體圖,第5圖係搭載於同一實 施形態之冰箱之壓縮機的概略截面圖,第6圖係同一實施形 態之冰箱之搬運狀態的概略截面圖,第7圖係同一實施形態 之冰箱搬運時之壓縮機的概略截面圖。此外,與習知技術 相同之結構附上同一標號。 在第1圖至第4圖中,隔熱箱體1具有隔熱壁,該隔熱壁 係於由將ABS等樹脂體真空成型之内箱13與使用預敷鋼板 等金屬材料之外箱14構成之空間注入用以發泡填充之隔熱 體15而成者。隔熱體15使用硬質聚胺酯發泡體、酚發泡體 或聚苯乙烯發泡等。若發泡材使用碳氫化合物系之環戊 烷,由防止溫暖化之觀點更佳。 隔熱箱體1採用區隔成複數隔熱區,上部為旋轉門式, 下部為拉出式之結構。由上開始為冷藏室2、並列設置之拉 出式轉換室16及製冰室17、拉出式蔬菜室3、拉出式冷凍室 4。於各隔熱區分別藉由墊圈18設置隔熱門。從上開始為冷 藏室旋轉門5、轉換室拉出門19、製冰室拉出門20、蔬菜室 拉出門6、冷凍室室拉出門7。 冷藏室旋轉門5設有門槽21作為收納空間,冰箱内設有 複數收納架22。於冷藏室2最下部設有儲藏盒23。 又,隔熱箱體1之外箱14係將從頂面内部切割之鋼板彎 13 201122393 曲成W之體24、底面面板25、背面面板26、構成使頂面 後方凹fe之凹。卩27之機械室面板⑺確保密封性而組裝構 成。機械室28藉鋼板之弓1伸加卫成型,為提高加工性,角 落部採R形。藉此_,可確保用以發泡充填之隔熱體以 分歧或合流部之流路,而使流純佳,而可防止因充填不 足發生之空隙。 此外,機械至面板28中,壓縮機"之配置部最深,向 左右端收束為較淺之形狀,藉此,亦可確健發泡填充用 之隔熱體15分歧或合流部之流路,而使流動性佳。 再者由於機械室面板28為引伸加工,故用以發泡填 充之密封部少即可’而可有利於卫時。若藉板金加工構 成同樣之形狀,不僅引伸模具費用減少,且可提高無引伸 皺痕之加工性與尺寸精確度。 又,機械室面板28於各面設置複數抽氣孔(圖中未示), 在不妨礙外觀及内觀下,可防止因殘留空氣造成之空隙產 生或變形。 又’於底面面板25及背面面板26設置由可勾住手指之 凹陷構成的把手。底面把手29在從底面前方至中央之位置 於二處間隔預定間隔設置,而可從前方以手指勾住。背面 把手30在背面面板26之最上部之大致最高處之二處間隔預 定間隔而設置,而可向上以手指勾住。 又’内箱13較外箱14小一圈’背面裡部為向内側凹陷 之結構’將之組裝入外箱14中,可於隔熱箱體1形成發泡填 充用之空間。因而,機械室面板28之左右部亦發泡填充隔 14 201122393 熱體15,而構成隔熱壁,以確保強度。進而,底面把手29 或背面把手30亦藉用以發泡填充之隔熱體15確保強度。 又,冷凍循環系統係將彈性支撐於凹部27而配設之壓 縮機11、設於壓縮機11附近之機械室風扇31、設置於殼體 24頂面、凹部27、底面面板25下部或殼體24側面等之冷凝 器(圖中未示)、作為減壓器之毛細管32、進行去除水分之 乾燥機(圖中未示)、位於蔬菜室3與冷床室4背面,將冷卻 風扇8配置於附近而設置之蒸發器9及吸入配管33連接成環 狀而構成。 凹部27設有以小螺釘等固定之頂面蓋34,而收納設於 凹部27之壓縮機11、冷凝器(圖中未示)、機械室風扇、乾 燥機及配管等。 毛細管32與吸入配管33為大約同等長度之銅管,且餘 留端部而焊接成可進行熱交換。毛細管32為減壓而使用内 部流動阻力大之細徑銅管,其内徑為0.6mm至1.0mm左右, 可與長度一同調節,以設計減壓量。吸入配管33為減低壓 力損失,而使用大徑銅管,其内徑設置為6.35mm至7.94mm 左右。又,為確保熱交換部35之長度,使其蜿蜓而匯集成 小型,於冷藏室2之背面呈蜿蜒部,配置於内箱13與背面面 板26中間而埋設於隔熱體15。毛細管32與吸入配管33使其 一端部從内箱13之蔬菜室3後方位置突出而與蒸發器9連 接,使另一端部從設置於機械室面板28深處之缺口部(圖中 未示)突出至上方而分別與乾燥機(圖中未示)、冷凝器及壓 縮機11連接。 15 201122393 此外,由於使配管從溫度較高之蔬菜室3後方取出或置 入冰箱内,故可使配管取出置入而造成之侵入熱量增加的 影響小而對省能源有效。 又,在吸入配管33上,防止油流出阱36設置於與壓縮 機11之連接部附近,並收納於凹部27。為以提高組裝作業 性及服務作業性為目標,而減輕配管密集度,且可從後方 目視配管連接部,而將壓縮機11之配管連接部面向背面側 而分別配置於壓縮機之左右。 吸入配管3 3從壓縮機11之背面側下方部於側邊設置略 為上升之斜坡而前進後,於略垂直方向較壓縮機11之垂直 方向中心線高且低於壓縮機11高度之位置設置直立部。為 使凹部27最小,且往冰箱内之突出為最小,壓縮機11之小 型化與壓縮周圍壁面之空間需儘可能縮小,在上下方向將 配管高度設置為壓縮機11之高度以下,可謀求防止配管之 壁面接觸。 再者,吸入配管33於垂直方向直立後,設置由朝隔熱 箱體1前方設置之配管U形彎曲部3 7構成之防止油流出阱 36,配管U形彎曲部37之前端較壓縮機11之平面方向中心 線,靠近隔熱箱體1之前方側。由於壓縮機11形成朝向頂面 而具有曲率之形狀,故在壓縮機11上方構成配管U形彎曲部 37時,仍有多餘空間,不需另外採用配管收納空間,而可 小型化。且藉設置配管U形彎曲部37,可具有配管彈性,吸 收來自壓縮機11之振動傳導,而防止配管固定部之應力集 中,可減少配管破損。 16 201122393 二一機 接著’就壓縮機u内部之構造作說明。 在第5圖巾’壓縮機殼獅她細至4職之 引伸成形之钵狀下殼體38與倒钵狀上殼體39組合而重疊: 部份之殼體接合部4_圍焊接連結的密閉構造。壓縮^ 體4〇於其㈣具有轉性购馳切之__部42盥又 壓縮部43。以於壓縮機殼體4()内部開放端部之吸入配扣 及吐出配管44與構成冷;東循環系統之其他機器連接,並封 入預定量之油45及冷媒(圖中未示)。又,下殼體38下方部安 裝用以與隔熱㈣丨雜支撐之切料。此外,支撑祕 藉-段之段差設有用以魏·切構件厚度之排出部。 旋轉驅動部42由馬達47及軸承⑽構成。馬達47由具 有施加電壓而與永久磁_產錢轉力之中空圓柱狀電磁 線圈之定子概具有㈣定子州部並⑽小間隙相對之 久磁鐵之轉子5G構成。轴承部48由端部具有偏 心軸51 其内部為兩端開放中空體,周圍設有與螺旋狀溝(圖中未示) 内部連通之喷出孔之轴52及保持轴52使其旋轉自如之轴承 53構成。 壓縮部43由其前端設有具閥機構(圖中未示)之缸頭54 之缸體55、活塞56、搖動自如地安裳於活塞減偏心轴51, 以將旋轉動作轉換為直線往返動作之桿體57構成。於缸頭 54藉由閥機構連接管44’而可使經壓縮之冷媒直接 吐出至壓雜殼體·卜部。吸人部藉㈣機構而於壓縮機 17 201122393 殼體40内部開放。特別是為消音’吸入路徑於缸頭54及壓 縮機殼體40之吸入氣體路徑間配設消音器(圖中未示)。 另,吸入配管33配置成其開口端相對於壓縮機殼體40 内壁面呈同面,而可謀求壓縮機11之小型化。 就如以上構成之冰箱,說明其動作、作用如下。 首先,就各隔熱區之溫度設定及冷卻方式作說明。冷 藏室2為冷藏保存,通常以不結凍之溫度為下限而設定在 rC〜5°C。又,儲藏盒23為提高魚肉等之保鮮性,而設定在 比較低之溫度,例如-3°C〜1。(:。 轉換室16可根據使用者之設定’變更溫度設定,而從 冷凍室溫度帶至蔬菜室溫度帶進行預定之溫度設定。又, 製冰室17為獨立之冰保存室,具有自動製冰裝置(圖中未 示)’可自動製作、儲存冰。用以保存冰之冷凍溫度帶由於 以保存冰為目的,而設定在較冷凍溫度帶高之_18。(:〜-i〇°c。 蔬菜室3多設定為與冷藏室2相等或稍高之溫度 2°C〜7°C。以不結凍之程度呈低溫,可長期維持葉類蔬菜之 鮮度。 冷凍室4為冷凍保存,通常設定在-22°C〜-18°c,為提高 冷凉保存狀態’亦可設定在-3〇°C或-25 C之低溫。 各室為有效維持不同之溫度設定,以隔熱壁加以區 隔,而可低成本且提高隔熱性能之方法有以隔熱體15—體 發泡填充。較使用如發泡苯乙烯般之隔熱構件,約有2倍之 隔熱性能’可擴大因切割之薄型化造成之收納容積擴大。 接著,就冷凍循環系統之動作作說明。依冰箱内設定 201122393 之>服度,根據來自溫度感測器(圖中未示)及控制基板之信 號,開始及停止冷卻運轉。根據冷卻運轉之指示在壓縮 機11内部’從端子(圖中未示)經由電線施加電壓至旋轉驅動 部42之馬達47。 g馬達47 —運作時,定子49之電磁線圈磁化 ,而於與 具永久磁鐵之轉子50間產生旋轉力。藉轉子5〇之旋轉,在 轴承部48 ’固定於轉子50之軸52同步旋轉,偏心軸51亦偏 心旋轉。經由設置成藉偏心軸51之旋轉而搖動自如之桿體 57,活塞56於缸體55内進行往返動作。 藉此,在壓縮部43進行冷媒氣體之壓縮動作。即,當 活塞56移動至離缸頭54最遠之位置時,使缸體”内之壓力 下降,而使設置於缸頭54之吸入部之閥機構(圖中未示)開 放,壓縮機殼體40内之冷媒氣體便經由消音器(圖中未示) 進入缸體55内。接著,活塞56移動至最接近仏頭^之位置 時,吸入之冷媒氣體被壓縮而成為高溫高壓之冷媒氣體, 從缸體54之吐出部藉由閥機構吐出。吐出之冷媒氣體通過 直接連接於缸頭54之吐出配管44而送至壓縮機殼體4〇外。 如此,壓縮機殼體40内為存在低壓冷媒氣體之内部低 壓型結構,從吸入配管返回之冷媒氣體被釋放出至壓縮機 殼體40内。 存在於壓縮機11之承軸部48或壓縮部43之滑動部58藉 油45而確保潤滑性。再者,油45與冷媒氣體選擇有相溶性 之組合,有臭氧破壞係數低之汉1343與g旨油之組合、及地球 溫室化係數低且對環境保護佳之碳氫化合物系冷媒之 19 201122393 HC600a與礦物油之組合。 又,油45封入壓縮機殼體4〇内並儲存於下部,且規定 封入量,以確保預定之油面高度。對滑動部58之油45之供 給以轴52之旋轉之離心力,傳達至軸52之中空内部而進 行。軸52之下端完全為油45所沾附,從此處返回至軸52内 部之油45從設置於相對於滑動部58各部位之位置的喷出孔 (圖中未示)吹送。再者,藉軸52周圍之螺旋溝,可使對滑動 部58之油45之供給十分充足。 藉如以上之壓縮機U之動作而吐出之高溫高壓冷媒以 冷凝器(圖中未示)散熱,而冷凝液化,在毛細管32減壓後, 形成低溫低壓之液體冷媒而到達蒸發器9。 藉冷卻風扇8之動作,與冰箱内之空氣進行熱交換而使 蒸發器9内之冷媒蒸發氣化,將經熱交換之低溫冷氣以氣流 調節器等分配,而進行各室之冷卻。 離開蒸發器9之冷媒經由吸入配管33吸入至壓縮機 11。此時’由於吸入配管33焊接成可與毛細管32熱交換而 埋設於隔熱體15’故熱無法排出至周圍,而從低溫之吸入 配管33傳熱至高溫之毛細管32。由於毛細管32在冷媒之減 壓過程中冷卻’故降低比焓而使冷凍效果增加。吸入配管 33之冷媒溫度上升而在出口部大致與周圍溫度相等或在其 之上。由於吸入配管33之冷媒溫度上升,故吸入至麼縮機 11之過程之熱相失小’而可提南效率。產生冷;東溫度之冷 凍循環系統為使蒸發器9之冷媒溫度在-2〇t:以下之極低 溫,而為減低熱損失效果大者。 20 201122393 又’由於毛細管32比較咼溫,故配置於低溫部位時, 於與吸入配管33之熱交換之外產生散熱’而產生冷凍循環 系統之熱損失,且對冰箱内造成熱負荷,而使省能源性降 低。然而,由於於冰箱内溫度高之冷藏室2背面配置毛細管 32與吸入配管33,故不致使熱損失或冰箱内之熱負荷大幅 增加,而可確保省能源性。特別是由於可充分確保熱交換 部35之長度,且使其在冷藏室2背面蜿蜓,而收納成小变, 故可獲得省能源化及吸入配管33充分溫度上升。此外,由 於蜿蜓部為設置上升坡而無阱之結構,故液體冷媒或冷凍 機油不致坪留,而不致引起壓力損失等性能影響。 在進行以上動作之冰箱之搬運或移設時,如第6圖所 示,使用設置於底面面板25及背面面板26之底面把手29及 背面把手30,以4人等數人搬運。 冰相之重量It著伴隨内容積大型化或高機能化之附加 產品之增加、或因省能源化之密度大之真空隔熱材使用量 增加,而大幅增加。冰箱之外尺寸亦以高度在18〇〇mm左右 者為主流,寬度及深度亦在6〇〇111〇1至75〇〇1111左右而使搬 運之方法相當重要。 在將冰箱配送至客戶時,最好是採橫倒之搬運形觫 ,於底面及背面上部設置把手。且不僅是配送時,在二丄 或替換花紋等時,大多是於導入電源前使冰箱橫倒而象 搬運。 連行 而 内 藉該等把手結構’冰箱可進行使門面朝上之搬壤, 可防止搬運時,門突然開啟而對搬運者不安全,且冰_ 21 201122393 零件或收納物落下等問題。 此時,設置於頂面凹部27之壓縮機11内部,如第7圖所 示,於壓縮機殼體40内開放之吸入配管33之開口端沒入油 45中,而呈從吸入配管33逆流流出之狀態。然而,由於由 配管U形彎曲部37構成之防止油流出阱36相對於搬運時之 油45之滯留面,於上方直立而構成,故油45不致流出至吸 入配管33内與蒸發器9内。在搬運後,再設置時,防止油流 出阱36内之油45因重力返回壓縮機殼體40内,而不致一直 呈油45阻塞吸入配管33内之狀態。 如上,防止油流出阱36與壓縮機11 一同設於頂面之凹 部27,且當以使油流入於壓縮機11内開放之吸入配管33開 口端之斜度傾斜時,因以可防止油從壓縮機11内部流出至 蒸發器之斜度,故於因搬運等傾斜後,使冰箱直立時’亦 大致不致流出至頂面凹部27外之吸入配管内。且巧*防土油 從吸入配管33逆流流出至蒸發器9。 如上述,藉防止油流出阱36,於因搬運等傾斜後’使 冰箱直立時,由於流出至防止油流出阱36内之油返回至 縮機11内部,故可防止油滯留於位於壓縮機下方之吸入面 管及蒸發器,可解除壓縮機11内之油不足,確保對麼縮機 滑動部等之油供給,而可進一步減低壓縮機之損傷等。 由此可確保壓縮機殼體40内之油45在預定量’而防土 對滑動部58之供油不足,特別是壓縮機11之初始啟動之電 源導入時,對滑動部58之供油不足,故可提高進一步減低 壓縮機11之損傷等之信賴性高之冰箱。 22 201122393 另,為使凹部27在冰箱内之突出為最小限,可使冷凝 器為薄型而配置於頂面,亦可依序於凹部27並列配置壓縮 機11與機械室風扇31作為箱型結構,而確保上下方向之内 容積。當冷凝器為翅管式、金屬線管或螺旋翅片管等使外 表面積擴大之散熱能力增加時,在冷凝器之小型化或能力 增加之省能源化有成效。 又,冷凝器不僅可為強制空冷式,亦可為由熱傳導佳 地貼附於外箱23内側之銅配管構成之自然空冷式,亦可組 合配設於各室隔熱門體間之間隔壁而進行防滴之銅配管。 此外,當於冷媒使用HC600a時,由於冷媒氣體之比容 積增大,體積流量增加,故熱交換部之流速亦增加,促進 傳熱,對吸入配管33之溫度上升與毛細管32之冷卻之冷凍 效果之增加可提高效果,且與冷媒之相溶性大,氣體流速 亦大,而可使油45之循環性良好,在確保信賴性方面有利。 又,使用電動三向閥或電動膨脹閥等流路控制機構, 分開使用依區隔結構或溫度設定之結構之複數蒸發器,切 換複數毛細管,或控制減壓量,或者於壓縮機11停止時切 斷氣體等,可謀求更進一步之省能源化。特別是藉將流路 控制機構設置於位於隔熱箱體1頂面之凹部27,可減低對冰 箱内之熱負荷,而更具有省能源之效果。 又,冰箱搬運用背面把手30設於易確保強度之凹部27 下方,若在同一位置,將控制基板設於中央,於其兩側設 置背面把手30,可有效地配置空間,而達到内容積擴大之 效果。又,分別於頂面蓋34之上方左右設置背面把手30, 23 201122393 由於可排出壓縮機11之設置空間,而構成把手形狀,故可 使空間效率佳,在搬抬時,由於可握住隔熱箱體1之角落 部,故具有易搬抬之效果。藉在底面把手29方面亦設於底 面前方端,可握住角落部,而提高搬抬便利性。 又,隔熱箱體1之凹部27係以隔熱體15構成左右壁面, 而當僅以殼體24構成側面時,可提高壓縮機11之散熱性, 進而,可使配置於凹部27之零件空間增大。 又,在本實施形態中,壓縮機11設置於位在隔熱箱體1 之頂面後方之凹部27。然而,不將凹部等設於隔熱箱體1之 頂面部,而於平面狀之頂面部設置壓縮機11時,在蒸發器9 位於壓縮機11下方之冰箱中,同樣地,因冰箱之搬運等而 橫倒時,可防止油流出至配置於壓縮機11下方之吸入配管 33及蒸發器9等。因而,可確保壓縮機11内之油量,而可防 止油面高度大量減少,確保對壓縮機11之滑動部之油供 給,減低壓縮機11之損傷。 (第2實施形態) 第8圖顯示搭載於本發明第2實施形態之冰箱之壓縮機 的概略戴面圖。 在第8圖中,在壓縮機殼體40内,吸入配管33朝向壓縮 部而設有直立部,且在上部設置橫向之配管彎曲部,其開 口端朝向中央而構成。如此,藉以吸入配管33之結構而設 置之防止油流出阱36,使冰箱橫倒而進行搬抬時,即使因 壓縮機11之橫倒,移動油45,吸入配管33之開口端不致沒 入油45内,而可防止逆流流出。 24 201122393 因而,將壓縮機11配置於冰箱頂面’可防止冰箱橫倒 時之油45流出至配置於下方之吸入配管33及蒸發器9等,故 可確保壓縮機殼體4〇内之油45,可對滑動部58供給足夠之 油,而可進一步減低壓縮機之損傷等。 再者,由於不使油45逆流流出,故將連接壓縮機11之 吸入配管33直接埋設於隔熱體15 ’可刪減隔熱箱體1之凹部 27之配管收納空間,而可達成因冰箱内容積增加或隔熱壁 厚度增加而造成之省能源化。 又,將吸入配管直接連接於設於壓縮機殼體40内部之 吸入氣體路徑用以消音之消音器,而構成在内部路徑形成 防止油流出阱,不致吸入因壓縮機構成零件之熱影響而變 熱之冷媒氣體,而是直接從吸入配管吸入冷媒氣體,故可 提高效率,進一步謀求省能源化。 (第3實施形態) 第9圖顯示本發明第3實施形態冰箱之吸入配管主要部 份概略立體圖。此外,與習知技術相同之結構附上同一標 號。 在第9圖中,設於隔熱箱體1之凹部27之防止油流出味 36由從蒸發器9連接之第1吸入配管33a、與壓縮機11連接之 第2吸入配管33b及室59構成。室59較設於第1吸入配管33a 與第2吸入配管33b間之各吸入配管33a、33b之管徑大,並 具有20mm至40mm之外形。第1吸入配管33a從室59上方插 入’配管於其内部突出並設有開口端。第2吸入配管33b從 室59下方插入,配管開口端配置成與室59内部之壁面為同 25 201122393 一面。 藉此,使冰箱橫倒而進行搬抬時,因壓縮機11之橫倒, 使油45移動,第2吸入配管33b之開口端沒入油45内時,油 45暫時流出至室59内。然而,由於可以室59内之配管結構, 防止流出至第1吸入配管33a,故再度設置冰箱時,油45返 回至壓縮機殼體40内,而確保必要量。 因而,將壓縮機11配置於冰箱頂面,可防止冰箱橫倒 時之油45流出至配置於下方之吸入配管33及蒸發器9等,故 可確保壓縮機殼體40内之油45,可對滑動部58供給足夠之 油,而可進一步減低壓縮機之損傷等。 此外,從下部插入之配管於内部突出,而於室59之内 面下端部附近設置油回流孔時,可作為防止室59内之油之 滯留,且對液體冷媒之過渡返回,可暫時儲存,而防止直 吸入至壓縮機11之緩衝機構,而防止壓縮機之液體壓縮 等,進而減低壓縮機之損傷等。 (第4實施形態) 第10圖顯示本發明第4實施形態冰箱之吸入配管主要 部份概略立體圖。此外,與習知技術相同之結構附上同— 標號。 在第10圖中,防止油流出阱36將壓縮機11與吸入配管 33之連接部60配置成較壓縮機11之中心線’靠近隔熱箱體i 之前方側。吸入配管33從壓縮機連接部60設置略為上升之 斜坡而於橫向延伸後,於約略垂直方向設置直立部,然後, 在背面設置U形彎曲部,而埋設於隔熱體15。 26 201122393 藉此,使冰箱橫倒而進行搬抬時,即使因壓縮機 橫倒’移動油45,吸錢管33之開口端不致沒人位於壓縮 機11頂面之油45内’而可防止逆流流出。 因而,將壓縮機11配置於冰箱頂面,可防止冰箱橫倒 時之油45之流出至配置於下方之吸入配管33及蒸發器9 等,故可確保壓縮機殼體40内之油45,可對滑動部58供給 足夠之油,而可進一步減低壓縮機之損傷等。 又,由於將與吸入配管33之熔接連接部61設於吸入配 管33之背面垂直部,故可輕易進行配管熔接作業。 (第5貫施形態) 第11圖及第12圖顯示本發明第5實施形態冰箱之吸入 配管主要部份概略立體圖。此外,與習知技術相同之結構 附上同一標號。 在第11圖中’吸入配管33從壓縮機11之背面側下方部 於側邊設置略為上升之斜坡後直進,於約略垂直方向,在 較壓縮機11之垂直方向中心線高且低於壓縮機丨丨高度之位 置設置直立部。為使凹部27最小,且往冰箱内之突出為最 小’壓縮機11之小型化與壓縮周圍壁面之空間需儘可能縮 小’在上下方向將配管高度設置為壓縮機11之高度以下, 可謀求防止配管之壁面接觸。 再者。吸入配管33於垂直方向上升後,為包圍壓縮機 11周圍,至少三面配置成跨過壓縮機11中心線,而構成防 止油流出36阱。配管U形彎曲前端較壓縮機11之平面方向中 心線,靠近隔熱箱體之前方側。由於壓縮機11形成朝向頂 27 201122393 面而具有曲率之形狀,故在壓縮機li上方構成配管u形彎曲 部37時,仍有多餘空間,不需另外採用配管收納空間,而 可小型化。且藉設置配管U形彎曲部37,可具有配管彈性, 吸收來自壓縮機11之振動傳導,而防止配管固定部之應力 集中,可減少配管破損。 吸入配管33於防止油流出阱36之後,於略垂直方向彎 曲,而從機械室28之背面端部埋設於隔熱體15。 藉此,使冰箱橫倒而進行搬抬時,即使因壓縮機11之 橫倒,移動油45,仍可防止冰箱橫倒時之油45之流出至配 置於下方之吸入配管33及蒸發器9等,故可確保壓縮機殼體 40内之油45,可對滑動部58供給足夠之油,而可進一步減 低壓縮機之損傷等。 又,不論冰箱把手方向,即使冰箱於不同方向橫倒, 由於配管設置成包圍壓縮機周圍,故與於背面方向橫倒 時,同樣地可防止油45之流出,而使冰箱搬運之限制少, 而提高搬送性。 又,如第12圖所示,當將吸入配管33配置於與壓縮機 11之連接部相同方向時,可構成防止油流出阱而環繞壓縮 機11一周,可形成不易逆流流出之結構。 (第6實施形態) 第13圖顯示本發明第6實施形態之冰箱之吸入配管主 要部份概略立體圖。此外,與習知技術相同之結構附上同 一標號。 在第13圖中,壓縮機62為如旋轉型般之内部高壓型, 28 201122393 配設於設在隔熱箱體1頂面後方之凹部27。來自壓縮機62之 吐出配管63於壓縮機62内部開放,吸入配管64直接連接於 壓縮機62之吸入部。又’於隔熱箱體1之頂面部設置薄型冷 凝器65,從壓縮機62藉吐出配管63具有上升斜坡而連接。 再者,冷凝器65配置成較壓縮機62之1»土出配管連接部66, 靠近前方且高之位置。在冷凝器65之下流部,以設於凹部 27背面側之連接部與毛細管32連接而玎謀求作業性與服務 性之提高。 此外,亦於此連接部附近配置乾燥機(圖中未示)等。 冷凝器65藉機械室風扇31進行強制空冷,風路徑以頂 面防塵蓋67兼用蓋體而構成。頂面防塵蓋67之前面及側面 設有吸入開口部68,背面部設有吐出開口部69,於冷凝器 65之配置部與凹部27間設置間隔壁70而構成風路徑。 藉此,在使用冰箱把手搬運或移設時,而使冰箱橫倒 時,壓縮機亦橫倒,油45流入壓縮機内部開放之吐出配管 63之開口端。然而,因冷凝器65配置於上方,不致使油45 因自重而朝向冷凝機65内流出。 藉此,可防止當油45多量流出至冷凝器65時,位於冷 凝器65之配管或下游之毛細管32因油阻塞而對妨礙冷媒循 環產生之性能降低造成影響。 又’當包圍壓縮機62之周圍,至少三面跨過壓縮機62 中心線而配置吐出配管63時,不論把手,冰箱之橫倒方向 為何種方向,亦可防止油45之流出。 此外’在冷凝器65下游側,即使連接另外設置之冷凝 29 201122393 器,冷凝器65可作為配管阱,故無任何問題。 又’若使用旋轉式壓縮機’可使構成零件少,而有助 於小型化’亦對冷藏室在冰箱内之突出之小塑化或無效容 積刪減有效。 (第7實施形態) 第14圖顯示搭載於本發明第7實施形態之冰箱之壓縮 機之概略截面圖。此外,與習知技術相同之結構附上同一 標號。 就壓縮機100内部之構造作說明。 在第14圖中,壓縮機100之結構為將上殼體101與下殼 體102重疊而熔接連接之密閉構造,内部具有由以彈性體 103彈性支撐之旋轉驅動部1〇4及壓縮部1〇5構成之内部構 成零件。壓縮機100以吸入配管丨〇6及吐出配管1〇7與構成冷 凍循環系統之其他機器連接,並封入預定量之油1〇8及冷媒 (圖中未示)。 旋轉驅動部104由馬達1〇9及軸承部11〇構成。馬達1〇9 由具有施加電壓而與永久磁顧產生旋轉力之巾空圓柱狀 電磁線圈之定子111、及具有位於定子111内部並以微小間 隙相對之永久磁鐵之轉子112構成。 此外,當壓縮機100為配置於頂面而小型化時,在配置 自由度、重量、冰箱有效容積之方面為有利,而小型化之 方法有以下方法。於構成定子⑴之電磁線圈❹突極集中 卷繞式時,可使卷線集中而緊密地卷繞,而可小型化。又, 由於收納於料112之永久錢為諸如N辑稀土元素類之 30 201122393 水久磁鐵,故較一般使用之鐵氧體磁鐵之磁通量密度約大4 倍,而可使磁鐵之高度降低,使壓縮機100小型化。 在如此小型化之壓縮機100中,壓縮機内容積内,構造 物之内部構成零件所佔之容積增大,而使空間部縮小。當 空間部縮小時,則壓迫封入之冷凍機油之容積,而使冷凍 機油面高度上升,因些微之傾斜,易使冷凍機油逆流至吸 入配管。 又,軸134具有軸主軸部134a及相對於軸主軸部13乜偏 心之軸偏心部134b。軸主軸部134a之軸承部110具有承受載 重之A軸承131、及固定於上殼體1〇1且作為於搬運時等防止 内部構成零件傾斜之機構之B轴承132。 壓縮部105由於前端設有具閥機構(圖中未示)之缸頭 135之缸體136、活塞137、搖動自如地安裝於活塞137及偏 心軸133,以將旋轉動作轉換為直線往返動作之桿體138構 成。 於虹頭135藉由閥機構連接吐出配管1〇7,而可使經壓 縮之冷媒直接吐出至壓縮機100外部。吸入部藉由閥機構而 於壓縮機殼體100内部開放。特別是為消音,吸入路徑於缸 頭135與吸入配管1〇6之路徑間配設消音器(圖中未示)。 在具有如以上構成之壓縮機之冰箱中,於冰箱之搬運 移設而橫倒時,即使壓縮機1〇〇傾斜,由於以設於上殼體1〇1 之B軸承132支撐,故彈性支撐之旋轉驅動部1〇4或壓縮部 105等内部構成零件不致朝下殼體1〇2壁面大幅傾斜。因 而,可防止壓迫移動至傾斜側之冷床機油之容積,確保空 31 201122393 間部’故可防止油108易從吸入配管流出。 又,在本實施例中,以B軸承132實現内部構成零件之 傾斜防止用軸承構造。然而,傾斜防止機構使用於上殼體 101頂面設置以預定間隔嵌合於設在軸134前端部之開口部 之銷者或設置於上殼體101頂面之軸134外周側而使軸134 之前端部不致傾斜之引導構件或設置預定間隔之空隙而使 旋轉驅動部104不致傾斜預定量以上,而固定於上殼體1〇1 或下殼體102之引導構件,亦可發揮同樣之效果。 (第8實施形態) 第15圖為搭載於本發明第8實施形態之冰箱之壓縮機 之概略截面圖,第16圖為從上部觀看搭載於本發明第8實施 形態之冰箱之壓縮機内部者。 在圖中’在壓縮機100内部,吸入配管200大致與殼體 内部配設於同一面而不致延伸出下殼體201之壓縮機内 部’並配設成與吸入消音器202之吸入口 202a接近相對。 吸入配管200之殼體内開口部與殼體内面大致配設於 同一面之理由為在構造面上,防止對殼體内之内部構成零 件之吸入配管200之物理緩衝,以謀求小型化。 又’具有旋轉子203a及固定子203b之電動元件203以具 彈性構件之支撐部205為中介而彈性支撐於下殼體201。於 電動元件203之上部配置壓縮元件204。 又,依序設置壓縮機、冷凝器(圖中未示)、減壓器(圖 中未示)及蒸發器(圖中未示)而形成一連串之冷媒流路之冷 凍循環系統封入R600a作為冷媒。於壓縮機100内部封入以 32 201122393 對R600a相溶性大之礦物油作為原料之油2丨〇。 如此’在將電動元件203配置於下部之壓縮機100中, 隨壓縮機1〇〇之運轉而進行旋轉之電動元件2〇3之旋轉子 203a為不與油21〇緩衝,而考慮支撐部2〇5之高度及安裝位 置而配置。 又’於壓縮元件204形成與上殼體(圖中未示)或下殼體 201具有一定間隙之抵接部220。 以下,說明壓縮機100之詳細内容。 軸240具有以壓入或燒嵌固定旋轉子203a之主軸部241 及對主軸部241偏心而形成之偏心部242。缸塊250具有略呈 圓筒形之壓縮室251,同時,具有用以軸支軸240之主軸部 241之軸承部243,並形成於電動元件203上方。 此時’於旋轉子203a之壓縮元件204側形成旋轉子凹部 203c,軸承部243延伸出至此旋轉子凹部203c内,藉此,將 壓縮元件204嵌插於電動元件203之旋轉子之高度範圍内, 而實現小型化。 活塞260遊嵌於壓縮室251 ’以連結機構261連結於轴 240之偏心部241。將軸240之旋轉運動轉換成活塞260之往 返運動,活塞260將壓縮至251之空間擴大縮小,而吸入殼 體内之冷媒,從吸入消音器202之吸入口 202a吸入,藉由設 於缸頭252内部之閥(圖中未示),通過形成於缸塊25〇之吐 出消音器253、吐出管254、吐出軟管270,而吐出至殼體外 部之吐出配管。 為高壓配管之吐出管254係内徑l_5mm至3.0mm之鋼 33

可使固定子203b之積厚或旋轉子203a之積厚減低,而可使 電動元件小型化。 接著,就壓縮機100之動作作說明。 當壓縮機通電時,電流通過端子280、導線281,而流 至電動元件203之固定子203b,藉固定子203b產生之旋轉磁 場,旋轉子203a旋轉。藉旋轉子203a之旋轉,連結於旋轉 子之軸240之偏芯部242進行從軸240之軸心偏心之旋轉運

當壓縮機100長時間為不運轉之狀態時,R6〇〇a會液化 而形成液體冷媒290,而儲存於油21〇(較液化之R6〇〇a比重 34 201122393 重之礦物油)上部。如此,在冷媒液化之狀態下,液體冷媒 儲存於油上部之一般冷媒為c〇2冷媒與酯油或揮發油之組 合亦相同。相對於此,當一般習知冷媒使用尺134£1與醋油 時,油與液體冷媒之上下關係相反,液體冷媒儲存於下部, 酯油儲存於其上部。 如本實施形態,在使用液體冷媒290儲存於油21〇上部 之冷媒與油之組合之壓縮機100中,當使壓縮機1 〇〇傾斜 時’油210到達於與下殼體201内壁面大致同一面開口之吸 入配管200時’便易流出至殼體外,而使殼體内部之油21〇 減少,而使油面高度減少。 如此,當油面高度減少時,供給至壓縮元件204之滑動 部之油量便減少,而有產生滑動部之摩耗等之可能性。 針對此課題,在本發明中,使用單位體積之冷凍能力 較R134a小約1/2左右’較C02小約1/20左右之冷媒之 R600a。藉此’因可獲得與R134a或C02同等之冷凍能力, 故氣筒容積較Rl34a大約2倍’較c〇2約大20倍。壓縮機之 活塞按壓量亦與此氣筒容積之增加成比例而增大。即,由 於相當冷媒之單位時間之體積流量增大’故冷媒通過冷凍 系統内時之配管内流速較R134a約大2倍’較C〇2約大20 倍,而可使油快速返回至壓縮機丨00内部’而可防止殼體内 之油量不足。 又,有關因此冰相之搬運等造成之冷;東機油之降低, 使用輸入壓縮機之電源後,在10分鐘當中’至少一半以上, 即5分鐘以上,以較商用電源頻率高之轉速驅動壓縮機之轉 35 201122393 速時,因高旋轉’而使壓縮機之活塞按壓量增大。是故, 由於冷媒通過冷凍系統内時之配管内流速更增大,故可使 滯留於冷凍系統内之油210更快速返回壓縮機1〇〇内部,而 可防止殼體内之油量不足。 又’在本實施形態之壓縮機100中,可實現壓縮機之高 度方向之小型化’相對於習知一般小型壓縮機之全高 190mm〜200mm ’本實施形態之壓縮機100可謀求至145111111 高度方向之小型化。 當進行對壓縮機全高之小型化時,為避免油量減少或 油流出,封入壓縮機内部之油量之油面高度確保為與一般

Description of the Invention: [Technical Field of the Invention: j Field of the Invention The present invention relates to a refrigerator which improves the performance of preventing oil flowing out of a compressor as a refrigerating machine oil in a refrigerating cycle system. C. Prior Art In recent years, from the viewpoint of global environmental protection, refrigerators have been developed to be more energy-efficient, and it is required to improve their usability and storability. Conventionally, such a refrigerator is provided with a compressor or the like which forms a machine room, and is disposed on the top surface of the refrigerator body or the upper portion of the rear surface of the refrigerator body. This conventional method is disclosed in Japanese Laid-Open Patent Publication No. Hei 11-183014. Fig. 18 shows a conventional refrigerator structure described in Japanese Laid-Open Patent Publication No. Hei 11-183014. The refrigerator main body 1 is constituted by a structure of a refrigerating compartment 2, a vegetable compartment 3, and a freezing compartment 4 from the top, the refrigerating compartment 2 has a revolving door 5, the vegetable compartment 3 has a vegetable compartment drawing door 6, and the freezing compartment 4 has a freezing compartment pulling-out door 7 . In this configuration, the cooling unit 10 including the in-refrigerator fan 8 and the evaporator 9 is provided at the rear of the rear side of the freezing compartment 4 at a height substantially equal to the height dimension of the opening of the freezing compartment 4 in which the storage section is the lowermost storage compartment. . The compressor 11 is provided on the top surface of the refrigerator 2 which is inconvenient to use, or the recessed portion 12 provided in the upper portion of the back surface of the refrigerator body 1. The storage volume of the compressor 11 is moved to the upper side from the lower side of the partition wall of the compartment cold storage compartment 2 and the vegetable compartment 3, and when the internal volume of each storage compartment is constant, the position of the partition wall of the refrigerator compartment 2 and the vegetable compartment 3 is necessarily lowered. To the bottom, the storage in the vegetable compartment 3 can be easily taken out at 201122393. However, in the conventional structure, the evaporator is disposed near the bottom surface of the refrigerator body, and the suction pipe (not shown) connected to the compressor and the evaporator are disposed below the compressor. In the case of the delivery or transfer of the refrigerator that was originally delivered to the storefront, there was a problem that when the refrigerator was traversed and transported, the cold-cooled oil was flowed back from the compressor (hereinafter referred to as oil), and after the setting, Stay below. When the oil flows out against the flow, the amount of oil inside the compressor decreases. The suction pipe is designed to reduce the pressure loss. 35mm to 7. The outer diameter of about 94 mm is assumed to be 50 mm to 80 ml when the tube thickness is 5 mm' and the length is 2000 mm. Since the length of the suction pipe is limited to the length of heat exchange between the capillary and the suction pipe, the efficiency is increased, and the length of the suction pipe cannot be shortened. And 'when increasing the piping volume in the evaporator' becomes a very large volume. In addition, in order to reduce the pressure loss, when the diameter of the suction pipe is increased, the internal volume of the pipe is increased. On the other hand, since the oil storage amount of the compressor is disposed on the top surface, the effective volume of the top surface of the refrigerator can be effectively reduced to a small shape. However, once it is small, the oil storage amount is changed. The effect of the change in oil level is increased. Briefly, when the bottom surface of the compressor is in the shape of a square column of 140 mni and 100 mm, and the grain product of the internal storage part is empty, the oil level of 14 ml is changed to change the south face of the oil level of 1 mm. Even if only the previous 50ml to 80ml flow out, it is reduced by 3. 5mm to 5. 7mm oil level height. In fact, due to the volume of the internal storage and the higher the oil level, the larger the volume of the storage, the more the reduction in the oil level. 4 201122393 However, since the compressor 11 supplies the oil stored in the lower portion to the sliding portion by the differential pressure or the centrifugal force, the oil level is reduced, and the amount of oil supplied to the sliding portion is reduced to cause the sliding portion to be worn or the like. Further, when the oil in the piping is cooled, the refrigerant is slowly returned to the compressor, so that when the oil having a high viscosity flows out, it is less likely to immediately collide with the gravity and return to the compressor. SUMMARY OF THE INVENTION The refrigerator of the present invention comprises a heat insulating box, a cold, an east circulation system, an oil, and an oil outflow trap. The refrigeration cycle system sequentially has a compressor and a condensation provided in the heat insulating box. a regulator, a pressure reducer and an evaporator to form a series of refrigerant flow paths; and an oil leakage prevention trap is disposed in the suction pipe connecting the compressor and the evaporator to prevent oil from flowing out of the compressor to the evaporator side The compressor is internally low-pressure type and disposed on a top surface portion of the heat insulating box, and the evaporator is disposed below the compressor. The refrigerator of the present invention comprises a heat insulating box, a compressor and a condenser, wherein the heat insulating box system is provided with a recess at the rear of the top surface; the internal high pressure type compressor is disposed in the recess; the condenser is disposed at In the top surface of the heat insulating box, the compressor is connected to the condenser via a discharge pipe, and the condenser is disposed closer to the front side of the heat insulating box than the discharge pipe of the compressor.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a refrigeration cycle system having oil leakage from a compressor and a compressor disposed above the evaporator. Refrigerator. In the refrigerator of the present invention, when the compressor is disposed on the top surface of the refrigerator and the refrigerator is prevented from falling over, the oil flows out to the suction pipe and the evaporator disposed below, thereby ensuring the amount of oil in the compressor and preventing the oil level from being greatly increased. The reduction and the supply of the oil to the sliding portion of the compressor can further reduce the damage of the compressor and the like. The refrigerator of the present invention comprises a heat insulation box, which in turn has a refrigeration cycle system formed in the compressor, the condenser, the pressure reducer and the evaporator of the heat insulation box to form a series of refrigerant flow paths and is enclosed in the compressor. oil. The compressor is of internal low pressure type and is disposed on the top surface of the heat insulation box, and the evaporator is disposed below the compressor. The suction pipe connecting the compressor and the evaporator is provided to prevent oil from flowing out from the inside of the compressor to the evaporator side to prevent oil from flowing out. 201122393 In the refrigerator transportation or transfer from the original delivery to the store's logistics, when the refrigerator is transported across the refrigerator, the compressor is also traversed, and the oil flows into the open end of the suction pipe that is open inside the compressor. However, since the suction pipe of the present invention is provided to prevent the oil from flowing out of the trap, the oil does not flow out to the deep portion of the suction pipe, and the oil does not flow out from the suction pipe to the evaporator. Thereby, even if the refrigerator is placed upright after transportation or the like, it is possible to prevent the oil from flowing out of the trap and prevent the oil from remaining in the suction pipe and the evaporator which are located below the compressor. Therefore, by arranging the compressor on the top surface of the refrigerator, it is possible to prevent the oil from flowing out to the suction pipe and the evaporator disposed under the compressor when the refrigerator is traversed, thereby ensuring the amount of oil in the compressor and preventing the oil level. The drastic reduction is made, and the supply of oil to the sliding portion of the compressor is ensured, and the damage of the compressor or the like can be further reduced. In addition, since the internal volume of the suction pipe can be increased, the low pressure loss due to the expansion of the inner diameter and the length of the pipe can be extended, and the refrigeration effect due to the increase in the heat exchange length with the capillary can be expanded to save energy. . Further, in the refrigerator of the present invention, the heat insulating box has a concave portion at a rear side of the top surface, and the concave portion is provided with a compressor and an oil leakage prevention trap. Therefore, when the refrigerator is transported or transported in the refrigerator, when the compressor is placed at the rear portion of the top surface where the inclination of the compressor is increased, the oil can be prevented from staying in the trap by preventing the oil from flowing out of the trap. Suction piping and evaporator below the compressor. Further, in the refrigerator of the present invention, when the oil outflow prevention well is inclined and the front surface side of the heat insulating box body faces upward, oil can be prevented from flowing out from the compressor interior 8 201122393 to the evaporator side. Therefore, it is also possible to prevent oil from flowing out of the compressor when it is moved or moved so that the door in front of the refrigerator faces upward. Further, in the refrigerator according to the present invention, the oil-preventing prevention well has a U-shaped bent portion in which the pipe is bent in a U-shape before and after the heat insulating box, and at least one of the bent portions is disposed to be larger than a compressor. The center line is adjacent to the front side of the heat insulating box, and at least one portion of the suction pipe is disposed closer to the center line of the compressor than to the front side of the heat insulating box. When the front door of the refrigerator faces the horizontal direction or the lower side, the door is naturally opened, and it is unsafe for the carrier. In order to prevent the parts or the contents of the refrigerator from falling down, the refrigerator handles provided on the back and the bottom of the refrigerator are often used for the refrigerator. Handling or transfer. When the refrigerator is transported or moved, the oil is prevented from flowing out of the compressor when the refrigerator is turned over to the front door. In other words, when the compressor is so traversed, the oil leakage from the trap provided in the direction of the heat insulating box of the suction pipe is a pipe trap in the vertical direction. Therefore, even if the oil flows into the open end of the suction pipe which is opened inside the compressor, the oil is prevented from flowing out at least from the center of the compressor and the suction pipe provided to the upper side. Further, the U-shaped bent portion of the pipe can serve as an elastic portion to alleviate the vibration. Further, the refrigerator of the present invention is provided in the suction pipe to prevent the oil from flowing out of the compressor casing. Therefore, when the refrigerator is transported laterally, the oil is prevented from flowing backwards, and the piping of the concave portion of the heat insulating box of the compressor is cut off, and the volume of the ice (four) is increased or the thickness of the heat insulating wall is increased. Chemical. Furthermore, the refrigerant disposed in the compressor (4) is in the path of 201122393, and the muffler for muffling is directly connected to the suction pipe, and the muffler is used as the oil to prevent the oil from flowing out of the trap, so that the heat is not absorbed due to the components of the compressor. When the refrigerant gas is heated, the refrigerant gas is directly sucked into the suction pipe, thereby improving efficiency and achieving energy saving. Further, in the refrigerator of the present invention, the preventive oil flowing out of the suction pipe is a chamber in which the connection side of the evaporator protrudes from the upper side to the inner side, and the compressor connection side is connected from below. In this way, the piping well can be formed without piping the space required for bending, and the oil return during normal operation is not hindered. Further, in the refrigerator of the present invention, the oil supply outflow trap provided in the suction pipe is disposed such that the connection portion between the compressor and the suction pipe is closer to the center line of the compressor and is located in front of the heat insulating box. In this manner, when the refrigerator handle is placed on the back or the bottom surface of the refrigerator and the refrigerator is horizontally turned into the front door, the oil can be prevented from flowing out of the compressor. That is, when the compressor is thus traversed, the connection portion of the suction pipe is located above the center of the compressor. Therefore, since the open end of the suction pipe opened inside the compressor is located above the oil level, oil can be prevented from flowing out. Further, the internal low-pressure type compressor of the refrigerator of the present invention has a casing and a lower casing which are vertically divided. After the components are housed inside, the upper casing and the lower casing are hermetically joined at the casing joint portion, and the pipe erecting portion is disposed from the casing joint portion to the suction pipe provided on the lower casing side. In this way, the height of the compressor can be reduced, and the vertical portion can be adjusted to reduce the variation in the height of the oil level. Therefore, the recess of the heat insulating box can be reduced in capacity, and the expansion of the internal volume can be achieved. The indoors are miniaturized. Further, in the refrigerator of the present invention, the internal low-pressure type compressor is provided with an internal component tilt prevention mechanism. In this way, when the refrigerator is transported and transported, the tilt of the internal components can be prevented even if the compressor is tilted, and the volume of the refrigerating machine oil that is moved to the inclined side can be prevented from being pressed, and the space portion can be secured, so that the freezer oil can be prevented. The situation of flowing out of the suction pipe. Further, in the refrigerator of the present invention, the internal low-pressure type compressor has an upper and lower divided upper and lower casings. After the components are housed inside, the upper casing and the lower casing are hermetically joined at the casing joint portion, and the suction pipe provided on the lower casing side is opened to the inside of the compressor substantially on the same surface as the inner wall surface of the lower casing. When the compressor is tilted, the compressor is more likely to pass from the suction pipe to the suction pipe. After the conveyance or the like, even if the refrigerator is placed upright, the oil can be prevented from remaining in the suction pipe and the evaporator located below the compressor. Further, the refrigerator of the present invention encloses the refrigerant in the cold-wash cycle system. The above-mentioned refrigerant is in a state of being liquefied, which is lighter than the above-mentioned oil. When the compressor is tilted, the oil is more easily discharged from the combination of the refrigerant and the oil flowing out of the pipe. After the conveyance or the like, even if the refrigerator is placed upright, the oil can be prevented from staying in the suction pipe and the evaporator located below the compressor. Device. Further, in the refrigerator of the present invention, the refrigerant is sealed; the refrigerant of the east circulation system is R600a, and the oil of the compressor is a mineral oil. In this way, since the volume per unit time of the refrigerant is increased by A, the flow rate in the piping when the cold_cooled shirt is made is 2 times larger than that of R134a, and is increased by 10 times as much as c〇2, which can be retained in the cold system. The oil inside quickly returns to the inside of the compressor to prevent insufficient oil in the housing. Further, in the refrigerator of the present invention, the electric component is used as the commutating motor of the permanent magnet of the 201122393 rotator, and the bearing portion of the compression element is inserted in the height range of the rotator of the electric component, whereby the support can be supported by The components other than the internal components of the electric component and the compression component are configured to be miniaturized in the height direction. Therefore, the support member for supporting the compression element and the electric element is not reduced as the element, and the compression element and the electric element can be reduced in height, whereby the oil is not buffered with the internal components other than the support portion, and the oil surface is made The change in height is not easy to occur, and the oil can be prevented from flowing out of the suction pipe. Moreover, the refrigerator of the present invention includes a heat insulating box having a recessed portion at the rear of the top surface, an internal high pressure compressor disposed in the recessed portion, and a condenser provided on a top surface portion of the heat insulating box body, the compressor The condenser is connected to the discharge pipe, and the condenser is disposed closer to the discharge pipe connection portion of the compressor than to the front of the heat insulation box. Thereby, when the refrigerator is traversed, the compressor is also slanted, and the oil flows into the open end of the discharge pipe which is opened inside the compressor, so that the oil does not flow out to the directly connected condenser due to its own weight. It is possible to prevent the circulation of the refrigerant from being clogged by the condensing pipe or the downstream capillary oil when the oil is discharged to the condenser, and the performance is remarkably lowered or the reliability is deteriorated. Further, by arranging the compressor on the top surface of the refrigerator, it is possible to prevent the oil from flowing out to the suction pipe and the evaporator disposed below when the refrigerator is traversed, thereby ensuring the amount of oil in the compressor and preventing the oil level from being greatly reduced. To ensure the supply of oil to the sliding portion of the compressor, the damage of the compressor and the like can be further reduced. Hereinafter, embodiments of the present invention will be described with reference to the drawings. Further, the present invention is not limited by the embodiments. 12 is a schematic cross-sectional view of a refrigerator according to a first embodiment of the present invention, and FIG. 2 is a schematic rear view of the refrigerator of the same embodiment, and FIG. 3 is a schematic view of the refrigerator of the same embodiment. Fig. 4 is a schematic perspective view of a main part of a suction pipe of a refrigerator of the same embodiment, Fig. 5 is a schematic cross-sectional view of a compressor mounted in a refrigerator of the same embodiment, and Fig. 6 is a refrigerator of the same embodiment FIG. 7 is a schematic cross-sectional view showing a state in which the refrigerator is conveyed in the same embodiment. Further, the same structures as those of the prior art are attached with the same reference numerals. In the first to fourth figures, the heat insulating box 1 has a heat insulating wall which is a case 14 which is formed by vacuum molding a resin body such as ABS and a metal material such as a pre-coated steel plate. The space formed is injected into the heat insulator 15 for foaming and filling. The heat insulator 15 is made of a rigid polyurethane foam, a phenol foam, or a polystyrene foam. If the foamed material is a hydrocarbon-based cyclopentane, it is more preferable from the viewpoint of preventing warming. The heat insulation box 1 is divided into a plurality of heat insulation zones, the upper part is a revolving door type, and the lower part is a pull-out type structure. From the top, the refrigerating compartment 2 is provided with a pull-out type conversion chamber 16 and an ice making chamber 17, a pull-out vegetable compartment 3, and a pull-out type freezing compartment 4.

The refrigerating compartment revolving door 5 is provided with a door slot 21 as a storage space, and a plurality of storage racks 22 are provided in the refrigerator. A storage box 23 is provided at the lowermost portion of the refrigerating compartment 2. Further, the outer casing 14 of the heat insulating box 1 is a steel plate that is cut from the inside of the top surface. The body 24 is bent into a body 24, the bottom surface panel 25, and the rear surface panel 26, and is configured to have a concave shape on the rear surface of the top surface. The machine room panel (7) of 卩27 ensures the seal and is assembled. The machine room 28 is formed by the extension of the steel plate bow 1 to improve the workability, and the corner portion adopts an R shape. By this, it is possible to ensure a flow path for the foaming and filling of the heat insulating body to be divergent or merged, and to make the flow pure, and to prevent voids due to insufficient filling. Further, in the machine-to-panel 28, the arrangement portion of the compressor " is the deepest, and the right and left ends are converged into a shallow shape, whereby the heat-dissipating body 15 for the foaming filling can be surely divided or merged. Road, and make the liquidity good. Further, since the machine room panel 28 is subjected to the drawing process, it is possible to use a small number of sealing portions for foam filling, which is advantageous for the tempering time. If the same shape is formed by sheet metal processing, not only the cost of the drawing die is reduced, but also the workability and dimensional accuracy of the non-extension wrinkle can be improved. Further, the machine room panel 28 is provided with a plurality of suction holes (not shown) on each surface, and it is possible to prevent the occurrence or deformation of voids caused by residual air without impeding the appearance and the inside. Further, a handle formed by a recess that can hook the finger is provided on the bottom panel 25 and the back panel 26. The bottom handle 29 is disposed at a predetermined interval from the front to the center of the bottom surface at a predetermined interval, and can be hooked by a finger from the front. The back handle 30 is disposed at a predetermined interval between the substantially uppermost portions of the uppermost portion of the back panel 26, and can be hooked upward with a finger. Further, the inner casing 13 is smaller than the outer casing 14, and the inner portion of the back surface is recessed toward the inner side. The assembly is placed in the outer casing 14, and a space for foaming filling can be formed in the heat insulating casing 1. Therefore, the left and right portions of the machine room panel 28 are also foamed and filled with the heat body 15 to form a heat insulating wall to ensure strength. Further, the bottom handle 29 or the back handle 30 is also secured by the heat insulating body 15 for foam filling. Further, the refrigeration cycle system is a compressor 11 that is elastically supported by the recess 27, a machine room fan 31 provided near the compressor 11, a top surface of the casing 24, a recess 27, a lower portion of the bottom panel 25, or a casing. A condenser such as a side surface (not shown), a capillary 32 as a pressure reducer, a dryer for removing moisture (not shown), and a back surface of the vegetable compartment 3 and the cold bed compartment 4, and the cooling fan 8 is disposed. The evaporator 9 and the suction pipe 33 provided in the vicinity are connected in a ring shape. The recessed portion 27 is provided with a top cover 34 fixed by a screw or the like, and accommodates a compressor 11, a condenser (not shown) provided in the recessed portion 27, a machine room fan, a dryer, a pipe, and the like. The capillary tube 32 and the suction pipe 33 are copper pipes of approximately the same length, and the remaining ends are welded to allow heat exchange. The capillary tube 32 is a reduced diameter copper tube having a large internal flow resistance and an inner diameter of 0. 6mm to 1. About 0mm, it can be adjusted together with the length to design the amount of decompression. The suction pipe 33 is for reducing the loss of the low-pressure force, and the large-diameter copper pipe is used, and the inner diameter thereof is set to 6. 35mm to 7. About 94mm. In addition, in order to ensure the length of the heat exchange unit 35, the heat exchange unit 35 is compacted and formed into a small portion on the back surface of the refrigerator compartment 2, and is disposed between the inner box 13 and the back surface panel 26 and embedded in the heat insulator 15. The capillary tube 32 and the suction pipe 33 have one end portion projecting from the rear of the vegetable compartment 3 of the inner box 13 and connected to the evaporator 9, and the other end portion is provided from a notch portion (not shown) provided deep in the machine room panel 28. The upper portion is protruded to be connected to a dryer (not shown), a condenser, and a compressor 11. 15 201122393 In addition, since the piping is taken out from the rear of the vegetable compartment 3 having a relatively high temperature or placed in the refrigerator, it is possible to reduce the influence of the increase in the amount of intrusion heat caused by the piping being taken in, and it is effective for energy saving. Further, in the suction pipe 33, the oil outflow prevention well 36 is provided in the vicinity of the connection portion with the compressor 11, and is housed in the concave portion 27. In order to improve the assembly workability and the service workability, the pipe density is reduced, and the pipe connection portion can be visually viewed from the rear, and the pipe connection portion of the compressor 11 faces the back side and is disposed on the right and left sides of the compressor. The suction pipe 3 3 is advanced from the lower side of the back side of the compressor 11 and is provided with a slightly rising slope on the side, and is erected in a position slightly higher than the center line in the vertical direction of the compressor 11 and lower than the height of the compressor 11 in the vertical direction. unit. In order to minimize the recess 27 and minimize the protrusion into the refrigerator, the size of the compressor 11 and the space for compressing the surrounding wall surface need to be reduced as much as possible, and the height of the pipe in the vertical direction is set to be lower than the height of the compressor 11, so that it can be prevented. The wall of the piping is in contact. Further, after the suction pipe 33 is erected in the vertical direction, the oil leakage outflow well 36 composed of the U-shaped bent portion 37 provided in front of the heat insulating box 1 is provided, and the front end of the U-shaped bent portion 37 of the pipe is larger than the compressor 11 The center line in the plane direction is near the front side of the heat insulating box 1. Since the compressor 11 has a shape having a curvature toward the top surface, when the U-shaped bent portion 37 of the pipe is formed above the compressor 11, there is still an extra space, and it is possible to reduce the size without requiring a separate piping accommodation space. Further, by providing the pipe U-shaped bent portion 37, it is possible to have pipe flexibility, absorb vibration conduction from the compressor 11, and prevent stress concentration in the pipe fixing portion, thereby reducing pipe damage. 16 201122393 The second machine is followed by the description of the internal structure of the compressor u. In the fifth figure, the 'compressor shell lion's thin-to-fourth-shaped extension-shaped lower casing 38 is combined with the inverted upper-shaped upper casing 39 to overlap: part of the casing joint portion 4_ welded joint Closed structure. The compression body 4 has a commissive portion and a compression portion 43. The suction and discharge pipes 44 at the open end of the compressor casing 4 () are connected to other machines constituting the cold and east circulation system, and are sealed with a predetermined amount of oil 45 and refrigerant (not shown). Further, a lower portion of the lower casing 38 is provided with a cut material for supporting the insulation (four). In addition, the section of the support secret-segment is provided with a discharge portion for the thickness of the Wei-cut member. The rotation drive unit 42 is composed of a motor 47 and a bearing (10). The motor 47 is composed of a rotor 5G having a permanent magnet having a voltage applied to the permanent magnetic core and having a torque of (4) a stator portion and a small gap (10). The bearing portion 48 has an eccentric shaft 51 at its end portion, and has a hollow body at its both ends, and a shaft 52 and a retaining shaft 52 that are connected to the inside of the spiral groove (not shown) are provided around the shaft to rotate freely. The bearing 53 is constructed. The compression portion 43 is provided with a cylinder 55 having a cylinder head 54 having a valve mechanism (not shown) at its tip end, a piston 56, and a rocker biasing shaft 51 for swinging to convert the rotation motion into a linear reciprocating motion. The rod body 57 is constructed. The cylinder head 54 is connected to the pipe 44' by a valve mechanism to directly discharge the compressed refrigerant to the press-fit housing. The suction department is opened inside the casing 40 by the (4) mechanism and the compressor 17 201122393. In particular, a muffler (not shown) is disposed between the suction head and the suction gas path of the cylinder head 54 and the compressor casing 40 for the sound-absorbing path. Further, the suction pipe 33 is disposed such that its open end is flush with the inner wall surface of the compressor casing 40, and the size of the compressor 11 can be reduced. As described above, the operation and function of the refrigerator will be described below. First, the temperature setting and cooling method of each insulation zone will be described. The cold storage compartment 2 is stored in a refrigerated state, and is usually set at rC to 5 °C with a temperature not lower than the freezing temperature. Further, the storage box 23 is set to a relatively low temperature, for example, -3 ° C to 1 in order to improve the freshness of fish and the like. (: The conversion chamber 16 can change the temperature setting according to the user's setting, and carry out the predetermined temperature setting from the freezer compartment temperature to the vegetable compartment temperature zone. Further, the ice making compartment 17 is an independent ice storage compartment, and has an automatic system. The ice device (not shown) can automatically make and store ice. The frozen temperature zone for storing ice is set to -18 in the frozen temperature zone for the purpose of preserving ice. (:~-i〇° c. The vegetable compartment 3 is set to a temperature equal to or slightly higher than the refrigerating compartment 2 by 2 ° C to 7 ° C. The temperature is not frozen, and the freshness of the leafy vegetables can be maintained for a long time. The freezing compartment 4 is cryopreserved. Usually set at -22 ° C ~ -18 ° c, in order to improve the cool storage state ' can also be set at -3 ° ° C or -25 C low temperature. Each room is effective to maintain different temperature settings to prevent heat The wall is partitioned, and the method for lowering the cost and improving the heat insulation performance is filled with the body 15 body foaming. Compared with the heat insulating member such as foamed styrene, the heat insulation performance is about 2 times. It is possible to expand the storage volume due to the thinning of the cutting. Next, the refrigeration cycle system The operation will be described. According to the setting of 201122393 in the refrigerator, the cooling operation is started and stopped according to the signal from the temperature sensor (not shown) and the control board. The compressor 11 is inside according to the instruction of the cooling operation. A voltage is applied from a terminal (not shown) via a wire to the motor 47 of the rotary drive unit 42. When the motor 47 is operated, the electromagnetic coil of the stator 49 is magnetized to generate a rotational force with the rotor 50 having the permanent magnet. By the rotation of the rotor 5, the shaft 52 fixed to the rotor 50 in the bearing portion 48' is rotated synchronously, and the eccentric shaft 51 is also eccentrically rotated. The piston 57 is swayed by the rotation of the eccentric shaft 51. The reciprocating motion is performed in the body 55. Thereby, the compression portion 43 performs the compression operation of the refrigerant gas. That is, when the piston 56 moves to the position farthest from the cylinder head 54, the pressure in the cylinder "is lowered, and the setting is made. The valve mechanism (not shown) of the suction portion of the cylinder head 54 is opened, and the refrigerant gas in the compressor casing 40 is introduced into the cylinder 55 via a muffler (not shown). Then, the piston 56 moves to the most Connect At the position of the head ^, the sucked refrigerant gas is compressed to become a high-temperature high-pressure refrigerant gas, and is discharged from the discharge portion of the cylinder 54 by a valve mechanism. The discharged refrigerant gas is directly connected to the discharge pipe 44 of the cylinder head 54. The compressor casing 40 has an internal low-pressure type structure in which a low-pressure refrigerant gas is present, and the refrigerant gas returned from the suction pipe is released into the compressor casing 40. The bearing portion 48 of the machine 11 or the sliding portion 58 of the compression portion 43 is lubricated by the oil 45. Further, the combination of the oil 45 and the refrigerant gas is compatible, and the oil having a low ozone destruction coefficient is 1343 and g oil. The combination of 19 201122393 HC600a and mineral oil with a combination of low-globalization factor and good environmental protection for hydrocarbon-based refrigerants. Further, the oil 45 is enclosed in the compressor casing 4 and stored in the lower portion, and the amount of sealing is specified to secure a predetermined oil level. The centrifugal force for the rotation of the shaft 52 to the oil 45 of the sliding portion 58 is transmitted to the hollow interior of the shaft 52. The lower end of the shaft 52 is completely adhered to the oil 45, and the oil 45 returned from the inside to the shaft 52 is blown from a discharge hole (not shown) provided at a position relative to each portion of the sliding portion 58. Further, the supply of the oil 45 to the sliding portion 58 is sufficiently sufficient by the spiral groove around the shaft 52. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor U described above is condensed and liquefied by a condenser (not shown), and after the capillary 32 is decompressed, a low-temperature low-pressure liquid refrigerant is formed to reach the evaporator 9. By the operation of the cooling fan 8, heat exchange with the air in the refrigerator causes the refrigerant in the evaporator 9 to evaporate and vaporize, and the heat-exchanged low-temperature cold air is distributed by a gas flow regulator or the like to cool the respective chambers. The refrigerant leaving the evaporator 9 is sucked into the compressor 11 via the suction pipe 33. At this time, the suction pipe 33 is welded to the heat insulating body 15 by heat exchange with the capillary 32, so that heat cannot be discharged to the surroundings, and the capillary 32 is transferred from the low temperature suction pipe 33 to the high temperature. Since the capillary 32 is cooled during the depressurization of the refrigerant, the specific effect is increased by lowering the specific enthalpy. The temperature of the refrigerant in the suction pipe 33 rises and is substantially equal to or above the ambient temperature at the outlet portion. Since the temperature of the refrigerant in the suction pipe 33 rises, the heat loss in the process of sucking into the compressor 11 is small, and the efficiency can be improved. The cold circulation system of the east temperature is such that the temperature of the refrigerant of the evaporator 9 is extremely low at -2 〇 t: or less, and the effect of reducing the heat loss is large. 20 201122393 In addition, since the capillary 32 is relatively cold, when it is disposed at a low temperature portion, heat is generated in addition to heat exchange with the suction pipe 33, and heat loss in the refrigeration cycle system occurs, and a heat load is generated in the refrigerator. Energy saving is reduced. However, since the capillary 32 and the suction pipe 33 are disposed on the back surface of the refrigerator compartment 2 having a high temperature in the refrigerator, heat loss or heat load in the refrigerator is not greatly increased, and energy saving can be ensured. In particular, since the length of the heat exchange unit 35 can be sufficiently ensured and the inside of the refrigerating compartment 2 is smashed and stored in a small size, it is possible to save energy and increase the temperature of the suction pipe 33 sufficiently. In addition, since the crotch portion has a structure in which the rising slope is provided without a well, the liquid refrigerant or the refrigerating machine oil is not left in the slab, and the performance loss such as pressure loss is not caused. When the refrigerator is transported or transported as described above, as shown in Fig. 6, the bottom handle 29 and the back handle 30 provided on the bottom panel 25 and the back panel 26 are transported by a person of four or more. The weight of the ice phase has increased significantly with the increase in the number of additional products with a large internal volume or high performance, or the increase in the use of vacuum insulation materials with a high density of energy saving. The size of the refrigerator is also about the height of about 18 〇〇mm. The width and depth are also around 6〇〇111〇1 to 75〇〇1111. The method of transportation is very important. When delivering the refrigerator to the customer, it is best to use a cross-cutting shape to set the handle on the bottom and back. Not only when it is delivered, but also when it is replaced by a second or a replacement pattern, the refrigerator is mostly transported before being introduced into the power supply. By the way, the handle structure is used. The refrigerator can move the facade upwards, preventing the door from opening suddenly and being unsafe to the carrier during transportation, and the ice or the hoisting of the parts or the storage items. At this time, the inside of the compressor 11 provided in the top surface concave portion 27, as shown in Fig. 7, the open end of the suction pipe 33 opened in the compressor casing 40 is not in the oil 45, but is flowed back from the suction pipe 33. The state of the outflow. However, since the oil leakage outflow well 36 formed of the U-shaped bent portion 37 of the pipe is formed to stand upright with respect to the stagnation surface of the oil 45 during transportation, the oil 45 does not flow out into the inside of the suction pipe 33 and the evaporator 9. After the transportation, when it is set again, the oil 45 which is prevented from flowing out of the trap 36 is returned to the compressor casing 40 by gravity, so that the oil 45 is not blocked in the suction pipe 33 at all times. As described above, the oil outflow trap 36 is provided in the recessed portion 27 of the top surface together with the compressor 11, and when the inclination of the opening end of the suction pipe 33 in which the oil flows into the compressor 11 is inclined, the oil can be prevented from Since the inside of the compressor 11 flows out to the inclination of the evaporator, when the refrigerator is erected after being tilted by transportation or the like, it does not substantially flow out into the suction pipe outside the top surface concave portion 27. And the anti-soil oil flows out from the suction pipe 33 to the evaporator 9 in a countercurrent flow. As described above, by preventing the oil from flowing out of the trap 36, when the refrigerator is erected after being tilted by the conveyance or the like, the oil which flows out to prevent the oil from flowing out of the trap 36 is returned to the inside of the compressor 11, so that the oil can be prevented from staying under the compressor. By suctioning the face tube and the evaporator, the oil shortage in the compressor 11 can be released, and the supply of oil to the sliding portion of the compressor can be ensured, and the damage of the compressor or the like can be further reduced. Thereby, it is ensured that the oil 45 in the compressor casing 40 is at a predetermined amount 'the oil supply to the sliding portion 58 is insufficient, and in particular, when the power supply of the initial start of the compressor 11 is introduced, the oil supply to the sliding portion 58 is insufficient. Therefore, it is possible to improve the refrigerator having high reliability such as further reducing the damage of the compressor 11. 22 201122393 In addition, in order to minimize the protrusion of the recessed portion 27 in the refrigerator, the condenser may be disposed on the top surface in a thin shape, and the compressor 11 and the machine room fan 31 may be arranged side by side in the recess portion 27 as a box structure. And ensure the inner volume of the up and down direction. When the condenser is a finned tube type, a wire tube or a spiral finned tube, the heat dissipation capability for expanding the external surface area is increased, and the energy saving of the condenser is reduced in size or capacity. Further, the condenser may be not only a forced air-cooling type, but also a natural air-cooling type which is formed by a copper pipe which is thermally adhered to the inside of the outer casing 23, and may be disposed in a partition wall between the heat insulating door bodies of the respective chambers. Carry out anti-drip copper piping. Further, when HC600a is used as the refrigerant, since the specific volume of the refrigerant gas increases and the volume flow rate increases, the flow rate of the heat exchange portion also increases, and heat transfer is promoted, and the temperature rise of the suction pipe 33 and the cooling effect of the cooling of the capillary 32 are promoted. The increase can improve the effect, and the compatibility with the refrigerant is large, and the gas flow rate is also large, so that the circulation of the oil 45 can be made good, and it is advantageous in securing reliability. Further, a flow path control mechanism such as an electric three-way valve or an electric expansion valve is used, and a plurality of evaporators having a structure of a partition structure or a temperature setting are separately used, switching a plurality of capillary tubes, or controlling a pressure reduction amount, or when the compressor 11 is stopped. By cutting off the gas and the like, it is possible to further save energy. In particular, by providing the flow path control mechanism in the recess 27 on the top surface of the heat insulating box 1, the heat load in the ice box can be reduced, and the energy saving effect is further enhanced. Moreover, the refrigerator-handling rear handle 30 is provided under the recess 27 which is easy to ensure strength, and at the same position, the control board is provided in the center, and the back handle 30 is provided on both sides, and the space can be effectively arranged, and the content can be expanded. The effect. Further, the back handles 30 are provided on the left and right sides of the top cover 34, respectively. 23 201122393 The handle space can be discharged by arranging the installation space of the compressor 11, so that the space efficiency is good, and the load can be gripped during the lifting. The corner of the hot box 1 has an effect of being easily lifted. By the bottom end handle 29, it is also provided at the front end of the bottom surface, so that the corner portion can be held, and the carrying convenience is improved. Further, the recessed portion 27 of the heat insulating box 1 constitutes the left and right wall surfaces by the heat insulator 15, and when only the side surface of the casing 24 is formed, the heat dissipation of the compressor 11 can be improved, and further, the components disposed in the recess 27 can be provided. The space increases. Further, in the present embodiment, the compressor 11 is provided in the recessed portion 27 located behind the top surface of the heat insulating box 1. However, when the recess 11 or the like is not provided on the top surface portion of the heat insulating box 1, and the compressor 11 is provided on the flat top surface portion, the refrigerator 9 is placed in the refrigerator below the compressor 11, and similarly, the refrigerator is transported. When it is traversed, it is possible to prevent the oil from flowing out to the suction pipe 33, the evaporator 9, and the like disposed under the compressor 11. Therefore, the amount of oil in the compressor 11 can be ensured, and the oil level can be prevented from being largely reduced, and the supply of oil to the sliding portion of the compressor 11 can be ensured, and the damage of the compressor 11 can be reduced. (Second Embodiment) Fig. 8 is a schematic perspective view showing a compressor mounted in a refrigerator according to a second embodiment of the present invention. In Fig. 8, in the compressor casing 40, the suction pipe 33 is provided with an upright portion toward the compression portion, and a lateral pipe bending portion is provided at the upper portion, and the opening end thereof is formed toward the center. In this way, when the oil is prevented from flowing out of the trap 36 by the structure of the suction pipe 33, and the refrigerator is moved upside down, even if the compressor 11 is traversed, the oil 45 is moved, and the open end of the suction pipe 33 is not immersed in oil. Within 45, it prevents backflow. 24 201122393 Therefore, the compressor 11 is disposed on the top surface of the refrigerator to prevent the oil 45 flowing out of the refrigerator from flowing out to the suction pipe 33 and the evaporator 9 disposed below, thereby ensuring the oil in the compressor casing 4 45, sufficient oil can be supplied to the sliding portion 58, and the damage of the compressor or the like can be further reduced. Further, since the oil 45 is not allowed to flow backward, the suction pipe 33 connected to the compressor 11 is directly embedded in the heat insulator 15', and the piping storage space of the recess 27 of the heat insulating box 1 can be eliminated, and the refrigerator can be realized. Energy savings due to increased volume or increased thickness of the insulation wall. Further, the suction pipe is directly connected to the muffler provided in the suction gas path inside the compressor casing 40 for muffling, and the internal path is formed to prevent the oil from flowing out of the trap, so that the suction does not change due to the heat influence of the components of the compressor. In the case of the hot refrigerant gas, the refrigerant gas is directly sucked from the suction pipe, so that the efficiency can be improved and energy saving can be further improved. (Embodiment 3) FIG. 9 is a schematic perspective view showing a main part of a suction pipe of a refrigerator according to a third embodiment of the present invention. Further, the same structures as those of the prior art are attached with the same reference numerals. In Fig. 9, the oil-proof outflow odor 36 provided in the recessed portion 27 of the heat insulating box 1 is composed of a first suction pipe 33a connected from the evaporator 9, a second suction pipe 33b connected to the compressor 11, and a chamber 59. . The chamber 59 has a larger diameter than each of the suction pipes 33a and 33b provided between the first suction pipe 33a and the second suction pipe 33b, and has a shape of 20 mm to 40 mm. The first suction pipe 33a is inserted from above the chamber 59. The pipe protrudes inside and is provided with an open end. The second suction pipe 33b is inserted from below the chamber 59, and the open end of the pipe is disposed to be the same as the wall surface of the interior of the chamber 59. As a result, when the refrigerator is moved upside down, the oil 45 is moved by the crossover of the compressor 11, and when the open end of the second suction pipe 33b is not filled into the oil 45, the oil 45 temporarily flows into the chamber 59. However, since the piping structure in the chamber 59 can be prevented from flowing out to the first suction piping 33a, when the refrigerator is again installed, the oil 45 is returned to the compressor casing 40, and the necessary amount is secured. Therefore, the compressor 11 is disposed on the top surface of the refrigerator, so that the oil 45 when the refrigerator is traversed can be prevented from flowing out to the suction pipe 33 and the evaporator 9 disposed below, so that the oil 45 in the compressor casing 40 can be secured. By supplying sufficient oil to the sliding portion 58, the damage of the compressor or the like can be further reduced. Further, the pipe inserted from the lower portion protrudes inside, and when the oil return hole is provided in the vicinity of the lower end portion of the inner surface of the chamber 59, it can be used as a prevention of oil retention in the chamber 59, and can be temporarily stored for the transition of the liquid refrigerant. It prevents direct suction into the buffer mechanism of the compressor 11, and prevents liquid compression of the compressor, etc., thereby reducing damage to the compressor and the like. (Fourth Embodiment) FIG. 10 is a schematic perspective view showing a main part of a suction pipe of a refrigerator according to a fourth embodiment of the present invention. Further, the same structures as those of the prior art are attached with the same reference numerals. In Fig. 10, the oil outflow trap 36 is disposed so that the connection portion 60 between the compressor 11 and the suction pipe 33 is disposed closer to the front side of the heat insulating box i than the center line ' of the compressor 11. The suction pipe 33 is provided with a slightly rising slope from the compressor connecting portion 60, and is extended in the lateral direction. The upright portion is provided in the approximately vertical direction, and then a U-shaped bent portion is provided on the back surface to be buried in the heat insulator 15. 26 201122393 Therefore, when the refrigerator is moved upside down, even if the compressor is moved over the 'moving oil 45, the open end of the suction pipe 33 is not placed in the oil 45 on the top surface of the compressor 11' and can be prevented. Flowing countercurrently. Therefore, by disposing the compressor 11 on the top surface of the refrigerator, it is possible to prevent the oil 45 flowing out of the refrigerator from flowing out to the suction pipe 33 and the evaporator 9 disposed below, so that the oil 45 in the compressor casing 40 can be secured. Sufficient oil can be supplied to the sliding portion 58, and damage to the compressor or the like can be further reduced. Further, since the welded connection portion 61 to the suction pipe 33 is provided in the vertical portion on the back surface of the suction pipe 33, the pipe welding operation can be easily performed. (Fifth Aspect) FIG. 11 and FIG. 12 are schematic perspective views showing main parts of a suction pipe of a refrigerator according to a fifth embodiment of the present invention. Further, the same structures as those of the prior art are attached with the same reference numerals. In Fig. 11, the suction pipe 33 is straightly advanced from the lower side of the back side of the compressor 11 to the side, and is straight in the vertical direction, and is higher in the vertical direction than the center line of the compressor 11 and lower than the compressor. Set the upright part at the height of the 。. In order to minimize the size of the recessed portion 27 and to minimize the protrusion into the refrigerator, the space for miniaturization of the compressor 11 and the space for compressing the surrounding wall surface should be reduced as much as possible. The height of the pipe is set to be lower than the height of the compressor 11 in the vertical direction, thereby preventing The wall of the piping is in contact. Again. After the suction pipe 33 rises in the vertical direction, it surrounds the periphery of the compressor 11, and at least three surfaces are disposed so as to straddle the center line of the compressor 11, thereby preventing the oil from flowing out of the 36 well. The U-shaped curved front end of the pipe is closer to the center line of the plane of the compressor 11, and is closer to the front side of the heat insulating box. Since the compressor 11 has a shape having a curvature toward the top surface 27 201122393, when the piping u-shaped bent portion 37 is formed above the compressor li, there is still a surplus space, and it is possible to reduce the size without requiring a separate piping accommodation space. Further, by providing the pipe U-shaped bent portion 37, the pipe elasticity can be absorbed, and the vibration conduction from the compressor 11 can be absorbed, and the stress concentration of the pipe fixing portion can be prevented, and the pipe damage can be reduced. The suction pipe 33 is bent in a slightly vertical direction after the oil is prevented from flowing out of the well 36, and is buried in the heat insulator 15 from the rear end portion of the machine room 28. Therefore, when the refrigerator is moved upside down and the oil is moved by the compressor 11, the oil 45 can be prevented from flowing out to the suction pipe 33 and the evaporator 9 disposed below when the refrigerator is traversed. In this way, the oil 45 in the compressor casing 40 can be secured, and sufficient oil can be supplied to the sliding portion 58, which further reduces damage to the compressor and the like. Further, regardless of the direction of the handle of the refrigerator, even if the refrigerator is slanted in different directions, since the piping is provided to surround the periphery of the compressor, when the horizontal direction is traversed, the outflow of the oil 45 can be prevented in the same manner, and the restriction on the handling of the refrigerator is small. And improve the transportability. Further, as shown in Fig. 12, when the suction pipe 33 is disposed in the same direction as the connection portion of the compressor 11, it is possible to prevent the oil from flowing out of the trap and surrounding the compressor 11 for one week, and it is possible to form a structure that is less likely to flow backward. (Embodiment 6) FIG. 13 is a schematic perspective view showing a main portion of a suction pipe of a refrigerator according to a sixth embodiment of the present invention. Further, the same structures as those of the prior art are attached with the same reference numerals. In Fig. 13, the compressor 62 is of an internal high pressure type as a rotary type, and 28 201122393 is disposed in a recess 27 provided behind the top surface of the heat insulating box 1. The discharge pipe 63 from the compressor 62 is opened inside the compressor 62, and the suction pipe 64 is directly connected to the suction portion of the compressor 62. Further, a thin condenser 65 is provided on the top surface portion of the heat insulating box 1, and the discharge pipe 63 is connected from the compressor 62 by a rising slope. Further, the condenser 65 is disposed closer to the front and higher than the 1» soil outlet pipe connecting portion 66 of the compressor 62. The flow portion below the condenser 65 is connected to the capillary 32 by a connection portion provided on the back side of the concave portion 27, thereby improving workability and serviceability. Further, a dryer (not shown) or the like is disposed in the vicinity of the connecting portion. The condenser 65 is forcedly air-cooled by the machine room fan 31, and the wind path is configured by using the top dust cover 67 as a cover. The front surface and the side surface of the top dustproof cover 67 are provided with a suction opening portion 68, and the discharge opening portion 69 is provided at the back surface portion. The partition wall 70 is provided between the arrangement portion of the condenser 65 and the concave portion 27 to constitute a wind path. As a result, when the refrigerator is moved or moved, the compressor is also traversed, and the oil 45 flows into the open end of the discharge pipe 63 which is opened inside the compressor. However, since the condenser 65 is disposed above, the oil 45 does not flow out into the condenser 65 due to its own weight. Thereby, it is possible to prevent the capillary 32 located in the piping or the downstream of the condenser 65 from being blocked by the oil when the oil 45 flows out to the condenser 65, thereby impairing the performance deterioration of the refrigerant circulation. Further, when the discharge pipe 63 is disposed at least three sides across the center line of the compressor 62 around the circumference of the compressor 62, regardless of the direction in which the refrigerator is tilted, the flow of the oil 45 can be prevented. Further, on the downstream side of the condenser 65, even if a separately provided condensation 29 201122393 is connected, the condenser 65 can function as a pipe trap, so that there is no problem. Further, if a rotary compressor is used, it is possible to reduce the number of components and contribute to miniaturization, and it is also effective for the small plasticization or ineffective volume reduction of the refrigerator compartment in the refrigerator. (Embodiment 7) FIG. 14 is a schematic cross-sectional view showing a compressor mounted in a refrigerator according to a seventh embodiment of the present invention. Further, the same structures as those of the prior art are attached with the same reference numerals. The configuration inside the compressor 100 will be described. In Fig. 14, the compressor 100 has a closed structure in which the upper casing 101 and the lower casing 102 are overlapped and welded, and the inside has a rotary drive unit 1〇4 and a compression unit 1 which are elastically supported by the elastic body 103.内部5 constitutes the internal components. The compressor 100 is connected to another machine constituting the refrigeration cycle system by the suction pipe 6 and the discharge pipe 1〇7, and is sealed with a predetermined amount of oil 1〇8 and a refrigerant (not shown). The rotary drive unit 104 is composed of a motor 1〇9 and a bearing unit 11〇. The motor 1〇9 is composed of a stator 111 having an empty cylindrical electromagnetic coil that applies a voltage to generate a rotational force with a permanent magnet, and a rotor 112 having a permanent magnet located inside the stator 111 and having a small gap therebetween. Further, when the compressor 100 is placed on the top surface and is downsized, it is advantageous in terms of arrangement degree of freedom, weight, and effective volume of the refrigerator, and the method of miniaturization has the following method. When the electromagnetic coil constituting the stator (1) is extremely concentrated, the winding wire can be concentrated and tightly wound, and can be miniaturized. Moreover, since the permanent money stored in the material 112 is a 30201122393 water-long magnet such as the N-type rare earth element, the magnetic flux density of the ferrite magnet is about 4 times larger than that of the commonly used ferrite magnet, and the height of the magnet can be lowered. The compressor 100 is miniaturized. In the compressor 100 thus miniaturized, the volume occupied by the internal components of the structure is increased in the internal volume of the compressor, and the space portion is reduced. When the space portion is reduced, the volume of the enclosed refrigerating machine oil is pressed, and the height of the refrigerating machine oil level is increased. Due to the slight inclination, the refrigerating machine oil is easily flowed back to the suction pipe. Further, the shaft 134 has a shaft main shaft portion 134a and a shaft eccentric portion 134b which is eccentric with respect to the shaft main shaft portion 13A. The bearing portion 110 of the shaft main shaft portion 134a has an A bearing 131 that receives the load, and a B bearing 132 that is fixed to the upper casing 1〇1 and that prevents the internal components from tilting during transportation. The compression unit 105 is provided with a cylinder 136 having a cylinder head 135 having a valve mechanism (not shown), a piston 137, and a piston 137 oscillatingly attached to the piston 137 and the eccentric shaft 133 to convert the rotation operation into a linear reciprocating motion. The rod body 138 is constructed. The Yuhongtou 135 is connected to the discharge pipe 1〇7 by a valve mechanism, so that the compressed refrigerant can be directly discharged to the outside of the compressor 100. The suction portion is opened inside the compressor casing 100 by a valve mechanism. In particular, the muffler is provided with a muffler (not shown) between the cylinder head 135 and the path of the suction pipe 1〇6. In the refrigerator having the compressor having the above configuration, when the refrigerator is transported and moved down, even if the compressor 1 is tilted, since the B bearing 132 provided in the upper casing 1〇1 is supported, the elastic support is supported. The internal components such as the rotary drive unit 1〇4 or the compression unit 105 are not greatly inclined toward the wall surface of the lower casing 1〇2. Therefore, it is possible to prevent the volume of the cold bed oil from being moved to the inclined side, and to ensure that the oil 108 is easily discharged from the suction pipe. Further, in the present embodiment, the B-bearing 132 realizes the structure for preventing the tilt of the internal component. However, the tilt preventing mechanism is provided on the top surface of the upper casing 101 so as to be fitted to the pin provided at the opening portion of the front end portion of the shaft 134 at a predetermined interval or the outer peripheral side of the shaft 134 provided on the top surface of the upper casing 101 to make the shaft 134 The guiding member that is not inclined at the front end or the gap of the predetermined interval is provided so that the rotation driving portion 104 is not inclined by a predetermined amount or more, and the guiding member fixed to the upper casing 1〇1 or the lower casing 102 can also exert the same effect. . (Embodiment 8) FIG. 15 is a schematic cross-sectional view of a compressor mounted in a refrigerator according to an eighth embodiment of the present invention, and FIG. 16 is a view of the inside of a compressor mounted in a refrigerator according to an eighth embodiment of the present invention as viewed from above. . In the figure, 'in the compressor 100, the suction pipe 200 is disposed substantially in the same plane as the inside of the casing without extending out of the compressor interior of the lower casing 201' and is disposed close to the suction port 202a of the suction muffler 202. relatively. The reason why the opening in the casing of the suction pipe 200 and the inner surface of the casing are disposed substantially on the same surface is to prevent physical buffering of the suction pipe 200 constituting the internal components in the casing on the structural surface, thereby achieving downsizing. Further, the motor element 203 having the rotor 203a and the stator 203b is elastically supported by the lower casing 201 via the support portion 205 having the elastic member. A compression element 204 is disposed above the motor element 203. Further, a refrigeration cycle system in which a series of refrigerant flow paths are formed by a compressor, a condenser (not shown), a pressure reducer (not shown), and an evaporator (not shown) to form a series of refrigerant flow paths is sealed in the R600a as a refrigerant. . An oil 2, which is a raw material of R600a, which is compatible with R600a, is sealed in the interior of the compressor 100. Thus, in the compressor 100 in which the electric component 203 is disposed in the lower portion, the rotor 203a of the electric component 2〇3 that rotates in accordance with the operation of the compressor 1〇〇 is not buffered with the oil 21〇, and the support portion 2 is considered. 〇5 height and installation position. Further, the compression member 204 is formed with an abutting portion 220 having a certain gap with the upper casing (not shown) or the lower casing 201. Hereinafter, the details of the compressor 100 will be described. The shaft 240 has a main shaft portion 241 that presses or inserts the fixed rotor 203a, and an eccentric portion 242 that is formed to be eccentric to the main shaft portion 241. The cylinder block 250 has a compression chamber 251 having a substantially cylindrical shape, and has a bearing portion 243 for the spindle portion 241 of the shaft support shaft 240, and is formed above the electric component 203. At this time, the rotor sub- recess 203c is formed on the side of the compression element 204 of the rotor 203a, and the bearing portion 243 extends into the rotor recess 203c, whereby the compression element 204 is embedded in the height range of the rotor of the motor element 203. And achieve miniaturization. The piston 260 is fitted to the compression chamber 251' and coupled to the eccentric portion 241 of the shaft 240 by a coupling mechanism 261. The rotary motion of the shaft 240 is converted into a reciprocating motion of the piston 260, and the piston 260 expands and contracts the space compressed to 251, and the refrigerant sucked into the casing is sucked from the suction port 202a of the suction muffler 202 by being disposed in the cylinder head. The valve (not shown) of the 252 is discharged through the discharge muffler 253, the discharge pipe 254, and the discharge hose 270 formed in the cylinder block 25, and is discharged to the discharge pipe outside the casing. The discharge pipe 254 for the high pressure pipe is an inner diameter of l_5 mm to 3. 0mm steel 33 201122393 The tube is formed to have an L-shaped or U-shaped bent portion, and has flexibility, and the compression member 204 is elastically coupled to the discharge hose 270 of the housing. Further, the motor element 203 is used for a commutation motor in which the rotor 203 uses a permanent magnet. In the conventional induction motor, when the accumulated thickness of the stator 203b or the rotor 203a is small, the torque required for the operation of the compressor 100 cannot be generated. However, the variable current motor using the permanent magnet for the rotor 203a does not require the magnetizing current required for the rotational torque, so that the thickness of the stator 203b or the thickness of the rotor 203a can be reduced. Miniaturize the electric component. Next, the operation of the compressor 100 will be described. When the compressor is energized, current flows through the terminal 280 and the wire 281 to the stator 203b of the motor element 203, and the rotor 203a rotates by the rotating magnetic field generated by the stator 203b. By the rotation of the rotor 203a, the eccentric portion 242 coupled to the shaft 240 of the rotor performs rotational motion eccentrically from the axis of the shaft 240. The eccentric motion of the shaft 240 is converted into a reciprocating motion by the coupling mechanism 261 coupled to the eccentric portion 242, and a reciprocating motion of the piston 260 coupled to the other end of the coupling mechanism 261 is formed, and the piston 260 surface changes the volume in the compression chamber 251. Perform inhalation compression of the refrigerant. The volume in which the piston 260 is sucked in and out of the compression chamber 251 in one round trip is called the air volume. The cooling capacity differs depending on the volume of the cylinder. Next, the case where the refrigerator is tilted by the conveyance or the like in the state where the compressor is stopped will be described. When the compressor 100 is in a non-operating state for a long period of time, R6〇〇a is liquefied to form a liquid refrigerant 290, and is stored in the upper portion of the oil 21〇 (more liquefied R6〇〇a specific gravity 34 201122393 heavy mineral oil). Thus, in the state in which the refrigerant is liquefied, the general refrigerant stored in the upper portion of the oil is the same as the combination of the c〇2 refrigerant and the ester oil or the volatile oil. On the other hand, when the conventional refrigerant uses a ruler 134 £1 and vinegar oil, the oil and the liquid refrigerant have a reverse relationship, the liquid refrigerant is stored in the lower portion, and the ester oil is stored in the upper portion. According to the present embodiment, in the compressor 100 in which the liquid refrigerant 290 is stored in the combination of the refrigerant and the oil in the upper portion of the oil 21, the oil 210 reaches the inner wall surface of the lower casing 201 when the compressor 1 is tilted. When the suction pipe 200 of the same opening is opened, it is easy to flow out of the casing, and the oil inside the casing is reduced by 21 ,, and the oil level is reduced. As described above, when the oil level is reduced, the amount of oil supplied to the sliding portion of the compression member 204 is reduced, and there is a possibility that the sliding portion is worn or the like. In order to solve this problem, in the present invention, the refrigeration capacity per unit volume is about 1/2 smaller than that of R134a, and R600a of the refrigerant which is about 1/20 smaller than that of C02. Therefore, since the refrigeration capacity equivalent to that of R134a or C02 is obtained, the volume of the gas cylinder is about 2 times larger than that of Rl34a, which is about 20 times larger than that of c〇2. The piston pressing amount of the compressor also increases in proportion to the increase in the volume of the cylinder. That is, since the volume flow rate per unit time of the refrigerant is increased, the flow rate in the piping when the refrigerant passes through the refrigeration system is about 2 times larger than that of R134a, which is about 20 times larger than C〇2, so that the oil can be quickly returned to the compressor.丨 00 inside 'to prevent the amount of oil in the housing is insufficient. In addition, the cold caused by the handling of the ice phase; the reduction of the east engine oil, after using the power supply of the input compressor, in at least half of the 10 minutes, that is, more than 5 minutes, the compression is driven at a higher speed than the commercial power supply frequency. Turn of the machine 35 201122393 When the speed is high, the piston pressing amount of the compressor is increased due to the high rotation. Therefore, since the flow rate in the piping when the refrigerant passes through the refrigeration system is increased, the oil 210 retained in the refrigeration system can be returned to the inside of the compressor 1 more quickly, and the amount of oil in the casing can be prevented from being insufficient. Further, in the compressor 100 of the present embodiment, the height of the compressor can be reduced. The total height of the compressor is 190 mm to 200 mm with respect to the conventional small compressor. The compressor 100 of the present embodiment can be oriented to the height of 145111111. Miniaturization. When miniaturizing the full height of the compressor, in order to avoid a decrease in the amount of oil or an outflow of oil, the oil level of the amount of oil enclosed in the compressor is ensured to be about 30 mm equivalent to that of a conventional small compressor. Therefore, the height of the oil level is about 12% to 13% with respect to the full height of the conventional compressor. In the small compressor of the present embodiment, the "full height of the compressor is increased to about 17% with respect to the oil level" when the compressor is tilted. At the time, the outflow of oil becomes a bigger issue. In response to this problem, when the compressor 1 of the present embodiment is downsized, the height of the compression element 2〇4 and the electric element 203 is reduced, and the compressor is downsized. That is, the portion of the support portion 205 that does not elastically support the mechanical portion composed of the compression element 204 and the motor element 2〇3 serves as a height reduction element, and the mechanical portion of the compression element 204 and the electric element 2〇3, that is, the internal components In order to reduce the height, the oil 210 is not buffered by the electric component 203 of the mechanical part, and the oil level change is not easily generated. Thus, the compressor 100 is disposed in the upper part of the refrigerator main body, and the compressor is a major problem. The miniaturization of the height direction of 100, in the direction of miniaturization of coal, 36 201122393, or the promotion of oil, and in the direction of promoting oil outflow, in other words, this embodiment adopts the above-mentioned miniaturization element to maintain the reliability of suppressing oil outflow. The combined structure. Further, the height from the uppermost portion of the oil surface of the oil 210 to the opening of the suction pipe 200 ensures a dimensional relationship equal to or higher than that of the conventional compressor, and the oil 210 can be suppressed from coming out. For example, by the suction pipe, the opening position of the casing is located above the maximum height ι/2 of the casing, and the effect of preventing the oil from flowing out when the compressor 100 is inclined is increased. In the present embodiment, since the abutting portion 220 having a certain gap with the upper casing (not shown) or the lower casing 201 is formed in the compression member 204, the abutting portion 22G and the upper casing are when the compressor is tilted. The body or the lower casing 2 () 1 abuts, so that the mechanical portion composed of the large-sized compression element 2〇4 and the electric element 2〇3 is not greatly inclined. Therefore, since the space portion of the oil moving to the inclined side can be prevented from being pressed and pressed, the space portion can be secured, so that the oil 1 8 can be prevented from easily flowing out of the suction pipe. (Ninth embodiment) Fig. 17 is a schematic perspective view showing a compressor mounted in a ninth embodiment of the present invention. In addition, the same components as those of the prior art are attached with the same reference numerals. Inside the compressor 100, the suction pipe 106 extends inside the casing, and is connected to the rainbow body by a direct suction type of the suction muffler 139 connected to the suction muffler 139 by the spring 106a of the elastic member. ^^. Further, the inside of the casing of the suction pipe ι 6 has an upwardly curved portion which is opened upward in the casing and is coupled to the spring 16a of the elastic member. Further, the suction muffler 139 is connected to the cylinder head 135, and is disposed in the same direction as the cylinder 136 37 201122393 or the cylinder head 135. The suction piping 1〇6 is also connected to the suction muffler 139 and disposed in the same direction. The discharge pipe 1〇7 is used to reduce the pressure pulsation, and the elasticity of the pipe is increased, and the predetermined pipe length is taken, and assembled to the lower body on the side opposite to the cylinder head. By arranging the suction pipe 1 〇 6 and the discharge pipe 1 〇 7 on the opposite side, a small compressor 10 可 can be constructed. With the above configuration, when the compressor 1 is tilted, only the gap between the cylinder 136, the valve gap of the cylinder head 135, and the oil return hole (not shown) provided in the suction muffler 39 are small. No countercurrent outflow of oil 1〇8 occurs. In addition, when the suction pipe 106 is engaged with the suction muffler 139 to form a tightly wound spring, in addition to reducing the transmission of the compression vibration, the oil 108 is also reduced in viscosity from the spring gap due to the viscosity, so that the oil can be reduced. Countercurrent. Further, in the present embodiment, the elastic member that connects the suction pipe 1〇6 and the suction muffler 139 uses a spring, and an elastic resin such as rubber may be used. Industrial Applicability The refrigerator of the present invention can prevent oil from flowing out of the compressor when the compressor is disposed in the cold beam (10) above the evaporator. Therefore, it is possible to reduce the coldness in the low-pressure reduction machine; in the case of the shortage of the east engine oil, it can be used not only as a household refrigerator but also as a refrigeration cycle system structure for a business refrigerator, a vending machine, or a storage room having other cooling machines.
