該等的下蓋一 51及吸口接頭55的主要的零件，是由 輕量且硬質的材料，例如由ABS樹脂等的合成樹脂材料 所形成。又’上蓋5 2是如後述以兩色成形的方式被形成 〇 第1吸入具7(以下僅稱爲吸入具7)，是在左右（ 寬幅〕方向的中央部的位置設有吸口接頭5 5。該吸口接 頭55是在下蓋51與上蓋52之間夾入有未圖示的一端而 可轉動地連接於吸口本體5 0。吸口接頭5 5具有：相對於 掃除面可從略水平的狀態轉動至略垂直的狀態（在上下方 向）的第1連接管55a ;以及一端可朝第1連接管55a的 另一端轉動地被連接，且相對於吸口本體5 0可朝左右方 向轉動的第2連接管55b。在第2連接管55b的另一端， 連接有延長管5、第2吸入具6。該吸口接頭5 5，是具有 例如使延長管5相對於掃除面呈略垂直的狀態，可使其延 長管：5朝向吸口本體50的左右方向傾倒的功能。藉此， 將操作管4朝向左右方向的任一方扭轉，可使吸口本體 50朝向左右方向的任一方向略90度旋轉，而可進行吸口 本體50在左右方向朝前後的移動方向的掃除。因此，可 沿著壁邊進行使吸入具7移動的掃除，將吸入具7插入狹 小的間隙的掃除。 又，在吸口本體5 0，從前部到左右側方，在下蓋5 1 與上蓋52之間界設有緩衝桿53。緩衝桿53是由橡膠' 彈性體等的彈性材料所形成，使用時，保持吸口本體5 0 內的氣密，並且在吸塵器1 (參閱圖1，以下相同）的使 -23- 201247159 用時，當吸口本體50與家具等衝突之際，可發揮吸收對 該家具等造成的受損與對吸口本體50的衝撃的緩衝材的 功能。 下蓋5 1的下面開口的吸入室40，是呈剖面略彎曲凹 狀（參閱圖13(b) )»在吸入室40的後方，開口形成 有吸入通路41。該吸入通路41是與吸口接頭55的前述 的通路R1連通。 在吸入室40的內面形成有肋43。肋43是在左右各 有4個，在兩側共計形成有8個。各肋43，是成爲旋轉 清掃體30的旋轉方向（參閱圖10中箭頭印XI)的下游 側的部位43a比成爲旋轉方向上游側的部位43b更朝向吸 入通路41側成傾斜的狀態突出而形成。 在肋43，當在吸入室40固定有旋轉清掃體30時， 形成旋轉清掃體3 0的刷毛3 3的前端部接觸。 在吸入室40的兩端部，形成有支撐旋轉清掃體30的 兩端的軸的軸承44、45，在該軸承44、45安裝有軸承蓋 44a (僅圖示一方），而形成可支撐旋轉清掃體30的兩端 〇 在本Η施形態，上蓋52由兩色成形而被形成。上蓋 52是如圖1 3 ( b )所示，作爲上蓋52的後側部位的1次 成形部52a (第1構件）由包含與前述同樣的抗靜電劑的 ABS樹脂所成形，作爲上蓋52的前側部位的2次成形部 52b (第2構件）由含有碳纖維的（包含）熱可塑性樹脂 (例如，聚丙烯、ABS樹脂）一體成形。因此，1次成形 -24 - 201247159 部52a與2次成形部5215雖同樣爲樹脂製，可疋，由於2 次成形部1 2 2包含碳纖維，所以2次成形部5 215對於1次 成形部52a具有強度，並且具備導電性。 又，由於1次成形部52a包含抗靜電劑’所以表面固 有抵抗値比由通常的ABS樹脂所成形者更低°因此’可 通過1次成形部52a將2次成形部52b帶電的靜電予以適 當地放電（防止帶電）° 此外，藉由吸口接頭55至1次成形部52&的部分呈 電連接的方式，或是由包含抗靜電劑的A B S樹脂成形吸 口接頭55至1次成形部52a的部分’可通過延長管5的 內管2 0，將延長管5所帶電的靜電經由1次成形部5 2 a 適當予以放電。 在本實施形態，構成使1次成形部52a與2次成形部 52b的交替部52c的附近部分在吸入具7的上下方向重叠 1次成形部52a與2次成形部52b，且僅以2次成形部 5 2b構成比此更前方側。亦即，在交替部52c，具有強度 的2次成形部52b與1次成形部52a —體被形成。 成形時，例如在鑄模灌入1次成形品用的材料形$ 1 次成形部52a，之後，在2次成形用的鑄模裝設1次成形 部52a，在交替部52c灌入2次成形品用的材料與1次成 形部i;2a重疊。藉此，2次成形部52b與1次成形部52a 從一體被成形。 此外’在2次成形部52b，如圖1 3 ( a ) ( b )所示， 設有根據吸入室40的負壓的大來開口的吸氣口 52e。 -25- 201247159 此外，重® 1次成形部52a與2次成形 範圍’雖爲了謀求輕量化所以盡量小爲理想 該等的緊貼性，在吸入具7的前後方向，設 52b的長度的3〜5成左右的重疊邊》 於此，圖13(b)所示，在吸入具7的 替部52c的前端是位在旋轉清掃體30的軸 體30的後端之間，交替部52c的後端是位 吸入室4〇的後端與上蓋52的後端之間。 藉由這樣的構成，由於僅以2次成形部 側’所以可將壁厚作薄，並謀求吸入具7的 ，吸入具7的操作性提昇。又，在吸入具7 電通過2次成形部52b在1次成形部52a適 此外，旋轉清掃體3 0是如圖13(b) 略圓筒狀的芯31 ;形成於該芯31的外周部E 安裝在該溝部3 2的刷毛3 3 ;以及由被配置 刷毛33之間的軟質材構成的板34而構成。 如圖1 2所示，旋轉清掃體3 〇朝以箭頭 方向旋轉時，由於刷毛33的前端部與肋43 13(b))，所以從下蓋5 1的下面開口被吸 屑等，是沿著旋轉清掃體30的旋轉方向朝丨 向被搬送。在該狀態，被吸入的塵埃、線屑 到旋轉清掃體3 0前碰到肋43的側面，並與

-26- 201247159 搬送到吸塵器本體2的未圖示的集塵部。 以下，說明由前述構成所獲得的效果。 (1) 由於延長管5的外管本體11及內管本體21由 含有碳纖維的熱可塑性樹脂所構成，所以作爲延長管5全 體可謀求輕量化並確保剛性。此外，以含有碳纖維的熱可 塑性樹脂成形吸塵器本體2的一部分（例如，下罩），亦 可謀求吸塵器本體2的輕量化並確保剛性。 (2) 由於操作管4的一部分或全部由包含抗靜電劑 的ABS樹脂所形成，所以可適當將在操作管4帶電的靜 電釋放到空氣中（大氣中），並且，可將在延長管5帶電 的靜電釋放到空氣中。因此，拿著操作管4之際，不易受 到電衝擊，可獲得靜電的放電性優的吸塵器1。 (3) 由於在下構件4b的連結口 4g直接連結有外管 本體U的一端部1 1 b，所以可通過下構件4b在操作管4 將在外管1 0 (延長管5 )帶電的靜電適當予以放電。因此 ，可獲得靜電的放電性優的吸塵器1。 (:4 )由於在內管本體2 1的另一端部2 1 c的一端部 2 1 c5設有放電構件29a而形成以框蓋29予以覆蓋’所以 可通過該放電構件29a適當將在延長管5帶電的靜電予以 放電。藉此，可獲得放電性優的吸塵器1。 (5 )吸入具7的1次成形部52a由於包含抗靜電劑 ，所以比起通常由AB S樹脂所成形者，表面固有抵抗値 變低，藉此，可通過1次成形部5 2 a適當將2次成形部 5 2b帶電的靜電予以放電。藉此，可獲得放電性優的吸塵 -27- 201247159 器1。 在前述實施形態，雖然由包含抗靜電劑的樹脂構成操 作管4，可是並不限於此，也可作成延長管5包含抗靜電 劑的構成。亦即，由包含碳纖維、抗靜電劑及熱可塑性樹 脂的樹脂構成延長管5的外管本體11及內管本體21，而 構成外管本體1 1及內管本體2 1具導電性，且具有放電性 ，並可構成延長管5本身具有放電性。 藉由如此的構成與前述的操作管4的放電性相互作用 ，而可在延長管5與操作管4的兩方將在延長管5帶電的 靜電予以放電，並可更迅速將在延長管帶電的靜電予以放 電。因此，可獲得放電性更優的吸塵器1。 此外，也可構成在操作管4不包含抗靜電劑，而在延 長管5含有抗靜電劑。 又，亦可由包含抗靜電劑的樹脂構成覆蓋導電線W 2 (導電構件）的外圍的延長管蓋所爲滑蓋28。 此時，也可藉由抗靜電劑的作用將滑蓋28帶電的靜 電適當予以放電。因此，可獲得放電性更優的吸塵器1。 此外，由鋁合金等的金屬材料形成外管本體11與內 管本體21時’也可通過操作管4將在外管本體11及內管 本體21所產生的靜電適當予以放電。 又，由於藉由射出成形可使外管本體11及內管本體 2 1的內面平滑化，所以可抑制因塵埃的衝突所產生的靜 電。 又，在前述實施形態’延長管5雖是以連結外管1〇 -28 ** 201247159 與內管20者作爲例示，可是並不限於此，也可由一個管 體所構成" [2 .延長管] 接著，針對成形構成吸塵器1所具備的延長管5的外 管本體11及內管本體21的材料進行說明。如前述，構成 延長管5的外管本體11與內管本體21是由以預定比例含 有碳繊維的熱可塑性樹脂（以下’稱爲適當「碳纖維含有 樹脂」。）構成。以下，針對該碳纖維含有樹脂進行說明 (碳纖維） 碳纖維含有樹脂所含有的碳纖維，是以高溫碳化纖維 狀之例如聚丙烯腈（PAN )樹脂、瀝青等的方式所獲得者 (短纖維），通常其90%以上由碳素所構成。這類的碳 纖維的具體的種類並沒有特別的限定，也可依據後述的碳 纖維的物性以任意的條件進行製造，又，也可使用市售品 。製造碳纖維時’其製造條件、原料等並沒特別限制，只 要適用周知的任意的製造條件及原料進行製造即可。又， 碳纖維並不一定要單獨使用1種，也可使用以任意的比率 及組合任意兩種以上。 碳纖維含有樹脂所含有的碳纖維的長度雖沒有特別限 制’但理想在1 mm以下。使用這樣的長度的碳纖維，由 於可更容易準備在外管本體U及內管本體21所含有的碳 -29- 201247159 纖維，所以可削減延長管5的製造成本。又，將這樣的長 度的碳纖維含有在外管本體11及內管本體21的方式，藉 此在構成外管本體11及內管本體21的碳纖維含有樹脂中 ，碳纖維彼此適當交絡，其結果，可達成良好的剛性。 碳纖維含有樹脂所含有的碳纖維的量，碳纖維含有樹 脂中爲5質量％以上、15質量％以下、理想爲10質量％ 以下。碳纖維的含有量包含在此範圍，藉此抑制延長管5 的製造成本，並且可使延長管5的輕量化及高剛性化均衡 佳地提昇。且還具有可容易將前述的上蓋體13 (參閱圖4 )及蓋體構件23 (參閱圖6)分別超音波熔接在外管本體 1 1及內管本體21的利點。關於這點，一面參閱圖14 一 面詳細說明。 圖14爲經由本發明者們的檢討所獲得的圖表，且是 以板狀的碳纖維含有樹脂的彎曲強度的關係槪念性的表示 使碳纖維的含有量變化時的板狀的碳纖維含有樹脂的厚度 (與形成延長管之際的外徑與內徑的長度的差對應。）及 該厚度的圖表。圖14中，各圖表附近的記載爲碳纖維（ CF)的含有量（質量％)， 「PP」表示作爲不含碳纖維 的熱可塑性樹脂的聚丙烯（CF含有量0質量％)。 又，縱軸的「86MPa」表示以往的吸塵器所使用的厚 度2mm的聚丙烯的彎曲強度。亦即，在由以往的厚度 2mm的聚丙烯構成的延長管，將該延長管以板狀成形之 際的板狀聚丙烯的彎曲強度爲86MPa。因此，若板狀樹脂 的彎曲強度在86MPa以上，則使用該板狀樹脂可成形具 -30- 201247159 有與以往至少同等以上的強度（剛性）的延長管。 畀者，橫軸的「〇.9mm」爲射出成形或吹塑成型可能 的小限度的厚度。因此，使用板狀樹脂進行射出成形或吹 塑成型成形延長管時，使用板狀樹脂成形延長管的厚度最 低要形成〇.9mm是極爲重要。 如圖1 4所示，具有相同厚度時，碳纖維含有樹脂中 的碳纖維含有量愈是增加，碳纖維含有樹脂的強度（必要 強度）増加。然而，碳纖維通常爲高價者，使碳纖維的含 有量增加的話，則碳纖維含有樹脂中的製造成本增加（價 格上昇）。再者，若使延長管的厚度增加，則其量也會使 延長管的質量也上昇（質量上昇）。又，根據本發明者們 的檢討，聚丙烯的比重爲0.92 g/cm3，而例如以10質量％ 的比例含有碳纖維的聚丙烯的比重爲0.95 g/cm3。因此， 由於含有碳纖維的聚丙烯的比重比不含碳纖維的聚丙烯更 大，所以只有使碳纖維的含有量增加時，即使同樣的厚度 重量也增加。 亦即，爲了使延長管5(更具體而言，外管本體11 及內管本體2 1 )的剛性提昇，即使只有使碳纖維的含有 量增加，也無法廉價製造延長管5，且重量也會增加。而 且，重量過度變的太重時，使延長管5的厚度減少時，後 述的成形會變的困難，且會變成無法確保延長管5通常所 要求的剛性。又，即使爲了維持同樣厚度，並廉價地製造 延長管5，而將碳纖維的含有量減少時，也無法確保延長 管5通常所要求的強度。再者’爲了確保這樣的剛性，而 -31 - 201247159 使延長管5的厚度增加時，則延長管5的重量會有變重的 可能性（質量增加）。 圖14所示的圖表，是有鑑於前述課題，本發明者們 檢討所獲得者。亦即，完全兼具製造之際的製造成本的削 減（廉價化）；通常所要求的強度的確保；以及輕量化的 延長管5，是經由本發明者們的銳意檢討所想到者。亦即 ，例如在含有聚丙烯與1 0質量％的比例的碳纖維的碳纖 維含有樹脂，要維持與構成以往的延長管的樹脂強度（板 狀的樹脂強度爲86MPa)同程度的強度時，當厚度超過約 2mm時會比構成以往的延長管的樹脂更重。 因此，將碳纖維的含有比例設在5質量％以上1 5質 量％以下時，不僅可成爲與構成以往的延長管的樹脂同程 度的強度，且可將厚度作的比以往（約2mm )更薄，而 且可將延長管做成比以往更爲輕量者。尤其，由於延長管 爲筒狀，所以與構成吸塵器的其他的構件相比容易破損， 總之輕量（亦即厚度薄）而且具高剛性是具有優秀的效果 。將具有這類的碳纖維含有量的碳素含有樹脂適用於延長 管’藉此可製造外管本體11及內管本體21的長方向中間 部，各自的外徑與內徑的差設在1 mm以上1 .4mm以下， 又，在長方向全域，將該差設在所謂2mm以下，比以往 更且輕量，而且高剛性的延長管。 又’依據由以5質量％以上15質量％以下的比例含 有碳纖維的碳纖維含有樹脂構成的延長管5，可藉由超音 波熔接更確實固定前述的上蓋體13及蓋體構件23。更具 -32- 201247159 體而霄，碳纖維的含有量愈是增加，則通常進行超音波溶 接會有變困難的傾向。然而，根據以前述比率含有碳纖維 的延長管5，可維持前述的廉價、輕量、高剛性，且也可 達到更確實進行上蓋體1 3及蓋體構件23的固定。再者， 藉由將碳纖維以前述的比率含有在熱可塑性樹脂時，也具 有特別容易藉由後述的射出成形或吹塑成型成形延長管的 利點。 (熱可塑性樹脂） 延長管5是由包含前述碳纖維的熱可塑性樹脂所構成 。前述的碳纖維的說明中，作爲熱可塑性樹脂雖舉聚丙烯 爲具體例，可是延長管5所含有的熱可塑性樹脂並不限於 聚丙烯。亦即，作爲形成延長管5的熱可塑性樹脂，可使 用周知的任意的熱可塑性樹脂（例如如前述使用 ABS ( Acrylonitrile-Butadiene-Styrene)樹脂等），其物性也只 要具備作爲延長管的功能可以隨意。可是，作爲形成延長 管5的熱可塑性樹脂爲輕量及廉價，且由所謂製造及使用 容易的觀點，如前述具體例所舉，使用聚丙烯爲理想。又 ，熱瓦塑性樹脂沒必要一定要單獨使用1種，亦可以任意 的比率及組合兩種以上。 又，在延長管5亦可含有前述的碳纖維及熱可塑性樹 脂以外的任意的成分。 接著，針對構成延長管5的由碳纖維含有樹脂構成的 外管本體11及內管本體21的製造方法進行說明。在本實 -33- 201247159 施形態，外管本體π及內管本體2 1，是分別將碳纖維含 有樹脂進行射出成形或吹塑成型所成形。以下，分成進行 射出成形時、與進行吹塑成型時的兩種成型，說明外管本 體11及內管本體12的製造方法。可是，外管本體11與 內管本體21爲形狀稍有不同，而基本上由於可以同樣進 行製造，所以在以下係以內管本體2 1的製造方法爲例進 行說明。又，爲了圖示的簡略化，將圖11及圖12的內管 本體21的形狀作成單純的筒形狀者。 (進行射出成形時） 使用碳纖維含有樹脂進行射出成形時，對其具體的方 法並無特別限制。以下，雖具體說明射出成形的方法，可 是射出成形的方法並不限於以下的內容。例如，如圖11 所示，將可成形筒形狀的外形（亦即圓柱形狀的外觀）的 金屬模（上模具100及下模具101);以及可成形圓筒形 狀的內徑的芯子102予以組合而形成一體者。然後，在將 該等予以組合之際產生的隙間，通過貫穿與芯子1 02形成 —體所形成的凸緣102a的貫穿孔102b，射出被加熱而熔 融的碳纖維含有樹脂（亦即擠出）。之後冷卻、及卸下金 屬模100、101及芯子102，並依需要切斷毛邊，形成內 管本體21。 射出熔融後的碳纖維含有樹脂之際的金屬模1 〇〇、 1〇1及芯子102的溫度雖爲任意，可是在碳纖維含有樹脂 的融點以下的溫度時，由於碳纖維含有樹脂會固化，所以 -34- 201247159 設定成比該融點溫度更高的溫度。又，射出之際的射出荷 重，由於會因碳纖維含有樹脂的溫度、組成而有所不同， 所以無法一槪而論，可是例如可設爲200MPa左右。此外 ，作爲進行射出成形之際的具體的裝置，例如可使用曰本 特開2010-131966號公報、日本特開2006-110905號公報 等記載的射出成型機。 藉由射出成形的方式成形內管本體21，藉此，除了 內管本體21的外形狀之外，也可精確佳地構成內形狀， 並可將內管本體21的內壁作成平滑者。因此，空氣在吸 塵器使用時的內管本體21內部流通之際，可減少空氣的 內部抵抗，可更進一步提昇具備吸塵器的電動送風機的運 轉效率。又，可抑制因內壁的凹凸造成空氣的亂流，並可 更進一步抑制伴隨亂流的噪音。再者，由於可以在一次的 工程一體成型延長管的整體，所以可謀求製造工程的簡化 (進行吹塑成型時） 使用碳纖維含有樹脂進行吹塑成型時，對其具體的方 法並無特別限制。以下，雖一面參照圖丨6，一面具體說 明吹塑成型的方法，可是吹塑成型的方法並不受限於以下 的內容。 例如將可成形圖1 6所示的筒形狀的外形的金屬模 2〇0、201予以組合，在該等的金屬模200、201的內部擠 出由碳纖維含有樹脂行成的型坯202 »之後’對型坯202 201247159 內部噴入高壓空氣，將型坯202推擠到金屬模200、201 內表面。然後，藉由冷卻金屬模2 00、201使型坯202固 化’卸下金屬模200、201之後，依需要切斷毛邊，可形 成內管本體21。 構成型坯201的碳纖維含有樹脂的溫度、將型坯201 擠出到金屬模200、201內表面之際的荷重、高壓空氣的 具體的壓力等並沒有特別限制，只要適用周知的任意的吹 塑成型法便可。此外，作爲進行吹塑成型之際的具體的裝 置，可使用例如在日本特開平11-277617號公報等作記載 的吹塑成型機。 藉由吹塑成形的方式成形內管本體21，藉此，由於 不使用芯子可成形內管本體21，所以可謀求芯子的拔出 等的製造工程的簡化。又，由於可在一次的工程成形內管 本體21的整體’所以由此觀點，亦可謀求製造工程的簡 化。

The inner tube body 21 (see Fig. 2(b)) is formed of a thermoplastic resin (for example, polypropylene, AB S resin) containing (including) carbon fibers. In the following description, the direction of each part is referred to as the one end (one end side) of the first suction device 7 along the air passage (not shown) to the cleaner body 2, which is close to the cleaner body 2. The opposite side is explained as the other end (the other end side). The outer casing of the cleaner body is covered by an upper cover and a lower cover. The upper cover is located on the upper side than the slightly center in the up-and-down direction, and the lower cover is located on the lower side than the slightly center in the up-and-down direction.

The dust collecting portion is located on the front side of the cleaner body 2 (the side on which the connection port 2a is formed). An openable and closable cover is formed on the front side of the upper cover. Therefore, the cover can open and close and close the upper portion of the dust collecting portion. As shown in FIG. 2, the operation tube 4 is formed in a cylindrical shape from the other end portion 4a connected to the extension tube 5 to one end 4a1 connected to the hose portion 3 (see Fig. 1), and further, cylindrically. The portion has a grip G extending from the other end portion 4a connected to the extension tube 5. The other end portion 4a is formed with a connection port 4g into which the one end portion 1 1 b of the outer tube 1 直接 of the extension tube 5 is directly inserted and connected. Here, the one end portion 1 1 b of the outer tube 10 of the extension tube 5 is formed of a thermoplastic resin containing carbon fibers and a body of the outer tube body, and is connected to the connection port 4g. That is, the connection port 4g is formed to directly connect the portion having the conductivity of the outer tube body 11, and the lower member 4b is in a state of being electrically connected to the outer tube body 1 1 via the one end portion 1 1 b. The grip G is composed of a lower member 4b which is provided integrally with the other end portion 4a, and an upper member 4c which is attached to the lower member 4b.

Further, in the mouthpiece body 50, from the front to the left and right sides, A buffer rod 53 is disposed between the lower cover 5 1 and the upper cover 52. The buffer rod 53 is formed of an elastic material such as a rubber elastic body, and in use, keeps the airtightness in the suction body 50, and in the vacuum cleaner 1 ( Referring to Fig. 1, the same applies to -23-201247159, when the mouthpiece body 50 collides with furniture or the like, it functions as a cushioning material for absorbing damage to the furniture and the like and punching the mouthpiece body 50. The suction chamber 40, which is open at the lower surface of the lower cover 51, has a slightly curved concave shape (see Fig. 13(b)). » In the rear of the suction chamber 40, the opening is formed with a suction passage 41. The suction passage 41 is a suction port. The above-mentioned passage R1 of the joint 55 is communicated with each other. The rib 43 is formed on the inner surface of the suction chamber 40. The ribs 43 are four on the left and right sides, and eight are formed on both sides. The ribs 43 are the rotary cleaning bodies 30. The direction of rotation (see arrow XI in Figure 10) The side portion 43a is formed to protrude from the portion 43b on the upstream side in the rotational direction so as to be inclined toward the suction passage 41. When the rotary cleaning body 30 is fixed to the suction chamber 40 in the rib 43, the rotary cleaning body 30 is formed. The front end portions of the bristles 3 3 are in contact with each other. Bearings 44 and 45 that support the shafts at both ends of the rotary cleaning body 30 are formed at both end portions of the suction chamber 40, and bearing caps 44a are attached to the bearings 44 and 45 (only the illustration One side is formed to support both ends of the rotary cleaning body 30, and the upper cover 52 is formed by two colors. The upper cover 52 is as shown in Fig. 13 (b) as the rear side of the upper cover 52. The primary molded portion 52a (first member) of the portion is formed of an ABS resin containing the same antistatic agent as described above, and the secondary molded portion 52b (second member) as the front side portion of the upper cover 52 is made of carbon fiber (including A thermoplastic resin (for example, polypropylene or ABS resin) is integrally molded. Therefore, the primary molding -24 - 201247159 portion 52a and the secondary molding portion 5215 are made of resin, and the secondary molding portion 1 2 2 contains carbon fibers. Therefore, the secondary molding portion 5 215 is applied to the primary molding portion 52a. It has strength and is electrically conductive. In addition, since the primary molded portion 52a contains the antistatic agent, the surface specific resistance 値 is lower than that of the normal ABS resin. Therefore, the static electricity that can be charged by the secondary molding portion 52a by the primary molding portion 52a is appropriately Ground discharge (preventing electrification) ° Further, the portion of the molded portion 52 & by the mouthpiece joint 55 is electrically connected, or the mouthpiece joint 55 to the primary molded portion 52a is formed of ABS resin containing an antistatic agent. The portion ' can pass the inner tube 20 of the extension tube 5 to discharge the static electricity charged by the extension tube 5 through the primary molding portion 5 2 a as appropriate. In the present embodiment, the vicinity of the alternating portion 52c of the primary molded portion 52a and the secondary molded portion 52b is superimposed on the primary molded portion 52a and the secondary molded portion 52b in the vertical direction of the suction tool 7, and only twice. The forming portion 52b constitutes a front side. That is, in the alternating portion 52c, the secondary forming portion 52b having the strength and the primary forming portion 52a are integrally formed. At the time of molding, for example, the material-shaped one-time molded portion 52a for the molded article is once poured into the mold, and then the primary molded portion 52a is placed in the secondary molding die, and the molded article is injected twice in the alternating portion 52c. The material used overlaps with the primary forming portion i; 2a. Thereby, the secondary molding portion 52b and the primary molding portion 52a are integrally formed. Further, in the secondary molding portion 52b, as shown in Fig. 13 (a) and (b), an intake port 52e which is opened according to the negative pressure of the suction chamber 40 is provided. -25-201247159 In addition, the heavy-duty one-time forming portion 52a and the secondary molding range 'supplement are as small as possible in order to reduce the weight, and the length of the buckle is set to 3 in the front-rear direction of the suction tool 7. ～50% overlapped side. Here, as shown in Fig. 13(b), the tip end of the replacement portion 52c of the suction tool 7 is located between the rear ends of the shaft bodies 30 of the rotary cleaning body 30, and the alternate portion 52c The rear end is between the rear end of the suction chamber 4〇 and the rear end of the upper cover 52. With such a configuration, since the wall thickness can be made thinner only in the second molding portion side, and the suction tool 7 is obtained, the operability of the suction tool 7 can be improved. Further, the suction tool 7 is electrically passed through the secondary molding portion 52b in the primary molding portion 52a, and the rotary cleaning member 30 is a core 31 having a substantially cylindrical shape as shown in Fig. 13(b); and is formed on the outer peripheral portion of the core 31. E is attached to the bristles 3 3 of the groove portion 3 2 and the plate 34 composed of a soft material disposed between the bristles 33. As shown in Fig. 12, when the rotary cleaning body 3 is rotated in the direction of the arrow, the front end portion of the bristles 33 and the ribs 43 13(b)) are sucked by the lower opening of the lower cover 5 1 and the like. The rotation direction of the rotary cleaning body 30 is conveyed toward the slanting direction. In this state, the sucked dust and the swarf hit the side surface of the rib 43 before being rotated by the cleaning element 30, and are conveyed toward the suction passage 41 in correspondence with each other. Further, the passage r1 of the suction port joint 5 5 is provided toward the side portion 52b of the cleaner body 2, but it is considered that the front-back direction of the forming portion is set twice, and the centering and the rotation cleaning are formed in the curved concave shape. Quantify. Thereby, the static discharge can be charged as shown, including: β groove portion 3 2; contact between the bristles 3 3 and the print X (refer to the dust entered in the figure, the arrow arrow printed on the X1 side, etc., is entangled The rib 4 3 is inclined and the passage 4 1 is conveyed, and is transported to the dust collecting portion (not shown) of the cleaner body 2 by -26-201247159. Hereinafter, the effect obtained by the above configuration will be described. The outer tube main body 11 and the inner tube main body 21 of the fifth embodiment are made of a thermoplastic resin containing carbon fibers, so that the entire length of the extension tube 5 can be reduced in weight and rigidity. Further, a part of the cleaner body 2 is molded of a thermoplastic resin containing carbon fibers. (For example, the lower cover), it is also possible to reduce the weight of the cleaner body 2 and ensure rigidity. (2) Since part or all of the operation tube 4 is formed of an ABS resin containing an antistatic agent, it can be appropriately placed in the operation tube 4. The charged static electricity is released into the air (in the atmosphere), and the static electricity charged in the extension tube 5 can be released into the air. Therefore, when the operation tube 4 is held, it is less susceptible to electric shock. The electric vacuum cleaner 1 is excellent in electrical discharge. (3) Since the one end portion 1 1 b of the outer tube body U is directly coupled to the joint port 4g of the lower member 4b, the outer tube 10 can be passed through the lower member 4b in the operation tube 4 ( The extension tube 5) the charged static electricity is appropriately discharged. Therefore, the electrostatic discharge device 1 having excellent electrostatic discharge can be obtained. (: 4) The end portion 2 1 c5 of the other end portion 2 1 c of the inner tube main body 2 1 is provided. The discharge member 29a is formed to be covered by the frame cover 29, so that the static electricity charged in the extension tube 5 can be appropriately discharged by the discharge member 29a. Thereby, the vacuum cleaner 1 having excellent discharge performance can be obtained. (5) The suction device 7 is provided. Since the primary molded portion 52a contains an antistatic agent, the surface specific resistance 値 is lower than that of the normal molded body of the AB S resin. Therefore, the secondary molded portion 5 2b can be appropriately replaced by the primary molded portion 5 2 a. The charged static electricity is discharged, whereby the dust-absorbing -27-201247159 device 1 having excellent discharge performance can be obtained. In the above embodiment, the operation tube 4 is made of a resin containing an antistatic agent, but the invention is not limited thereto. The extension tube 5 comprises an antistatic agent. The outer tube body 11 and the inner tube body 21 of the extension tube 5 are made of a resin containing carbon fibers, an antistatic agent, and a thermoplastic resin, and the outer tube body 1 1 and the inner tube body 21 are electrically conductive and have discharge properties. The extension tube 5 itself can be configured to have dischargeability. By such a configuration, the discharge of the operation tube 4 interacts with the extension tube 5 and the operation tube 4 to electrostatically charge the extension tube 5. The discharge is performed, and the static electricity charged in the extension tube can be discharged more quickly. Therefore, the vacuum cleaner 1 having better discharge performance can be obtained. Further, the operation tube 4 can be configured not to contain an antistatic agent, but the extension tube 5 can be contained. Antistatic agent. Further, the extension cover which covers the periphery of the conductive wire W 2 (conductive member) may be formed of a resin containing an antistatic agent as the slide cover 28. At this time, the static electricity charged by the slider 28 can be appropriately discharged by the action of the antistatic agent. Therefore, the cleaner 1 which is more excellent in dischargeability can be obtained. Further, when the outer tube main body 11 and the inner tube main body 21 are formed of a metal material such as aluminum alloy, the static electricity generated in the outer tube main body 11 and the inner tube main body 21 can be appropriately discharged by the operation tube 4. Further, since the inner surfaces of the outer tube main body 11 and the inner tube main body 21 are smoothed by injection molding, it is possible to suppress static electricity generated by the collision of dust. Further, in the above-described embodiment, the extension tube 5 is exemplified by the connection of the outer tube 1 〇 -28 ** 201247159 and the inner tube 20, but the invention is not limited thereto, and may be constituted by one tube. Extension pipe] Next, the material of the outer pipe main body 11 and the inner pipe main body 21 which constitute the extension pipe 5 provided in the cleaner 1 will be described. As described above, the outer tube main body 11 and the inner tube main body 21 constituting the extension tube 5 are composed of a thermoplastic resin containing a carbon dioxide in a predetermined ratio (hereinafter referred to as "a suitable "carbon fiber-containing resin"). In the following, the carbon fiber-containing resin is described (carbon fiber). The carbon fiber contained in the carbon fiber-containing resin is obtained by, for example, a polyacrylonitrile (PAN) resin or a pitch, which is obtained by carbonizing a high-temperature carbon fiber, for example, short fibers. More than 90% consist of carbon. The specific type of the carbon fiber is not particularly limited, and may be produced under any conditions depending on the physical properties of the carbon fiber to be described later, and a commercially available product may also be used. In the case of producing carbon fibers, the production conditions, raw materials, and the like are not particularly limited, and may be produced by applying any known production conditions and raw materials. Further, the carbon fibers are not necessarily used singly or in combination of any two or more in any ratio and in any combination. The length of the carbon fiber contained in the carbon fiber-containing resin is not particularly limited, but is preferably 1 mm or less. By using the carbon fiber of such a length, since the carbon -29-201247159 fiber contained in the outer tube main body U and the inner tube main body 21 can be prepared more easily, the manufacturing cost of the extension tube 5 can be reduced. In addition, in the carbon fiber-containing resin constituting the outer tube main body 11 and the inner tube main body 21, carbon fibers of such a length are contained in the outer tube main body 11 and the inner tube main body 21, and the carbon fibers are appropriately entangled with each other. Good rigidity. The carbon fiber contains the amount of the carbon fiber contained in the resin, and the carbon fiber contains 5% by mass or more and 15% by mass or less, preferably 10% by mass or less. The content of the carbon fiber is included in this range, whereby the manufacturing cost of the extension tube 5 is suppressed, and the weight reduction and the high rigidity of the extension tube 5 can be improved in a balanced manner. Further, it is possible to easily fuse the above-described upper cover 13 (see Fig. 4) and cover member 23 (see Fig. 6) to the outer tube main body 1 1 and the inner tube main body 21, respectively. In this regard, a detailed description will be made with reference to FIG. FIG. 14 is a graph obtained by the review by the inventors of the present invention, and the thickness of the plate-shaped carbon fiber-containing resin is changed when the content of the carbon fiber is changed by the relationship between the bending strength of the plate-shaped carbon fiber-containing resin. (corresponding to the difference between the outer diameter and the inner diameter of the extension tube) and a graph of the thickness. In the vicinity of each graph, the content of carbon fiber (CF) (% by mass) is shown, and "PP" is a polypropylene (CF content: 0% by mass) which is a thermoplastic resin containing no carbon fiber. Further, "86 MPa" on the vertical axis indicates the bending strength of polypropylene having a thickness of 2 mm used in the conventional vacuum cleaner. In other words, in the extension pipe made of a conventional polypropylene having a thickness of 2 mm, the bending strength of the plate-like polypropylene when the extension pipe was formed into a plate shape was 86 MPa. Therefore, when the bending strength of the plate-like resin is 86 MPa or more, the plate-shaped resin moldable article -30-201247159 is used as an extension pipe having at least the same strength (rigidity) as the conventional one. The leader, the horizontal axis of the "〇. 9mm" is a small thickness possible for injection molding or blow molding. Therefore, when a plate-shaped resin is used for injection molding or blow molding to form an extension tube, the thickness of the plate-shaped resin-formed extension tube is minimized to form a crucible. 9mm is extremely important. As shown in Fig. 14, when the thickness is the same, the carbon fiber content in the carbon fiber-containing resin increases, and the strength (required strength) of the carbon fiber-containing resin increases. However, carbon fiber is usually expensive, and if the content of carbon fiber is increased, the manufacturing cost in the carbon fiber-containing resin is increased (price is increased). Further, if the thickness of the extension pipe is increased, the amount of the extension pipe is also increased (the quality is increased). Further, according to the review by the present inventors, the specific gravity of polypropylene is 0. 92 g/cm3, for example, the specific gravity of the polypropylene containing carbon fiber in a proportion of 10% by mass is 0. 95 g/cm3. Therefore, since the specific gravity of the polypropylene containing carbon fibers is larger than that of the polypropylene containing no carbon fibers, even if the content of the carbon fibers is increased, the weight is increased even by the same thickness. That is, in order to increase the rigidity of the extension pipe 5 (more specifically, the outer pipe main body 11 and the inner pipe main body 2 1 ), even if only the content of the carbon fiber is increased, the extension pipe 5 cannot be manufactured inexpensively, and the weight is also increase. Further, when the weight is excessively excessive, when the thickness of the extension pipe 5 is reduced, the molding described later becomes difficult, and the rigidity required for the extension pipe 5 cannot be ensured. Further, even if the extension tube 5 is manufactured at a low cost in order to maintain the same thickness, and the content of the carbon fiber is reduced, the strength required for the extension tube 5 cannot be ensured. Further, in order to secure such rigidity, -31 - 201247159, when the thickness of the extension pipe 5 is increased, the weight of the extension pipe 5 may become heavier (increase in mass). The chart shown in Fig. 14 is based on the above-mentioned problems, and the inventors reviewed the obtained persons. In other words, the reduction in manufacturing cost (cost reduction) at the time of manufacture, the securing of the required strength, and the weight extension tube 5 are thought by the inventors. In other words, for example, a carbon fiber containing a carbon fiber in a ratio of polypropylene to 10% by mass contains a resin, and when the strength is the same as the strength of the resin (the plate-like resin strength is 86 MPa) constituting the conventional extension tube, the thickness is When it exceeds about 2 mm, it will be heavier than the resin which comprises a conventional extension tube. Therefore, when the content ratio of the carbon fibers is 5% by mass or more and 15% by mass or less, not only the strength of the resin constituting the conventional extension tube but also the thickness can be made thinner than in the related art (about 2 mm). Moreover, the extension tube can be made lighter than ever. In particular, since the extension tube has a tubular shape, it is more likely to be damaged than other members constituting the cleaner, and is excellent in weight (i.e., thin) and high in rigidity. A carbon-containing resin having such a carbon fiber content is suitably used for the extension tube', whereby the long-direction intermediate portion of the outer tube body 11 and the inner tube body 21 can be manufactured, and the difference between the outer diameter and the inner diameter of each is set at 1 mm. Above 1 . In addition, in the whole direction of the long direction, the difference is set to be 2 mm or less, which is lighter than the conventional one and has a high-rigidity extension tube. In addition, the upper cover 13 and the lid member 23 can be more reliably fixed by ultrasonic welding by the extension tube 5 made of a carbon fiber-containing resin containing carbon fibers in a ratio of 5% by mass or more and 15% by mass or less. More -32- 201247159 As the content of carbon fiber increases, it is often difficult to perform ultrasonic fusion. However, according to the extension tube 5 containing carbon fibers in the above ratio, the above-described inexpensive, lightweight, and high rigidity can be maintained, and the upper lid body 13 and the lid member 23 can be fixed more reliably. Further, when the carbon fiber is contained in the thermoplastic resin in the above ratio, it is particularly advantageous to form the extension tube by injection molding or blow molding which will be described later. (Thermoplastic Resin) The extension tube 5 is composed of a thermoplastic resin containing the above carbon fibers. In the above description of the carbon fibers, the thermoplastic resin is a specific example of the thermoplastic resin, and the thermoplastic resin contained in the extension tube 5 is not limited to polypropylene. In other words, as the thermoplastic resin forming the extension tube 5, any known thermoplastic resin (for example, ABS (Acrylonitrile-Butadiene-Styrene) resin or the like as described above) can be used, and the physical properties thereof can be provided as a function of the extension tube. random. However, as the thermoplastic resin forming the extension tube 5 is lightweight and inexpensive, and it is easy to manufacture and use, as described in the above specific examples, polypropylene is preferably used. Further, the hot-wafer plastic resin does not have to be used alone or in combination of two or more kinds in any ratio. Further, the extension tube 5 may contain any components other than the above-described carbon fiber and thermoplastic resin. Next, a method of manufacturing the outer tube main body 11 and the inner tube main body 21 made of a carbon fiber-containing resin constituting the extension tube 5 will be described. In the embodiment of the present invention, the outer tube body π and the inner tube body 21 are formed by injection molding or blow molding of a carbon fiber containing a resin. Hereinafter, the two methods of performing the injection molding and the blow molding are described, and the method of manufacturing the outer tube body 11 and the inner tube body 12 will be described. However, since the outer tube main body 11 and the inner tube main body 21 are slightly different in shape, and basically they can be manufactured in the same manner, the following description will be made by taking the manufacturing method of the inner tube main body 2 1 as an example. Further, for the sake of simplification of illustration, the shape of the inner tube main body 21 of Figs. 11 and 12 is a simple cylindrical shape. (In the case of injection molding) When the carbon fiber-containing resin is used for injection molding, the specific method is not particularly limited. Hereinafter, the method of injection molding will be specifically described, but the method of injection molding is not limited to the following. For example, as shown in FIG. 11, a metal mold (upper mold 100 and lower mold 101) capable of forming a cylindrical shape (that is, a cylindrical shape); and a core 102 capable of forming a cylindrical inner diameter are provided. Combine to form one. Then, the gaps generated when these are combined are passed through the through holes 102b of the flange 102a formed by forming the body with the core 102, and the carbon fibers containing the heated and melted resin are contained (ie, extruded). . Thereafter, the metal molds 100, 101 and the core 102 are cooled and removed, and the burrs are cut as necessary to form the inner tube body 21. The temperature of the metal mold 1 〇〇, 1〇1, and the core 102 when the carbon fiber after the melting of the carbon fiber is contained is arbitrary. However, when the carbon fiber contains a resin at a temperature lower than the melting point, the carbon fiber contains a resin, and the resin is solidified. -34- 201247159 Set to a temperature higher than the melting point temperature. In addition, since the injection load at the time of injection differs depending on the temperature and composition of the carbon fiber-containing resin, it cannot be clarified, but may be, for example, about 200 MPa. In addition, an injection molding machine described in, for example, JP-A-2010-131966 and JP-A-2006-110905 can be used as the specific device for the injection molding. The inner tube body 21 is formed by injection molding, whereby the inner shape can be accurately formed in addition to the outer shape of the inner tube body 21, and the inner wall of the inner tube body 21 can be made smooth. Therefore, when the air is circulated inside the inner tube body 21 when the vacuum cleaner is used, the internal resistance of the air can be reduced, and the operational efficiency of the electric blower equipped with the vacuum cleaner can be further improved. Further, it is possible to suppress turbulent flow of air due to the unevenness of the inner wall, and it is possible to further suppress noise accompanying turbulence. In addition, since the entire length of the pipe can be integrally formed in one project, it is possible to simplify the manufacturing process (during blow molding). When the blow molding is performed using a carbon fiber-containing resin, the specific method is not particularly limited. Hereinafter, the method of blow molding will be specifically described with reference to Fig. 6, but the method of blow molding is not limited to the following. For example, the metal molds 2〇0 and 201 which can form the outer shape of the cylindrical shape shown in Fig. 16 are combined, and after the parisons 202 made of carbon fiber containing resin are extruded inside the metal molds 200 and 201, 'The parison 202 201247159 is internally sprayed with high pressure air to push the parison 202 onto the inner surfaces of the metal molds 200, 201. Then, the parison 202 is solidified by cooling the metal molds 200 and 201. After the metal molds 200 and 201 are removed, the burrs are cut as necessary to form the inner tube body 21. The carbon fiber constituting the parison 201 contains the temperature of the resin, the load when the parison 201 is extruded onto the inner surfaces of the metal molds 200 and 201, and the specific pressure of the high-pressure air, and the like, and is not particularly limited as long as any well-known blow molding is applied. The molding method can be used. In addition, a blow molding machine described in, for example, Japanese Laid-Open Patent Publication No. Hei 11-277617, can be used as a specific device for the blow molding. The inner tube body 21 is formed by blow molding, whereby the inner tube body 21 can be formed without using a core, so that the manufacturing process such as the removal of the core can be simplified. Further, since the entire inner tube body 21 can be formed in one project, the manufacturing process can be simplified. As described above, the outer tube body 11 and the inner tube body 21 can be manufactured inexpensively, and are lightweight and highly rigid. In other words, as for the extension pipe 5 which is usually attached as an accessory to the cleaner, it is possible to improve the performance, and it is possible to provide a vacuum cleaner which improves the performance as a whole of the cleaner. Further, as described above, even if a carbon fiber-containing resin is used, injection molding or blow molding can be easily performed. Therefore, it is easy to form the so-called extension tube 5 (more specifically, the outer tube main body 11 and the inner tube main body 2 1 ). Further, the upper cover 13 and the lid member 23 can be easily and firmly fixed to the thermoplastic resin containing carbon fibers by ultrasonic welding. -36- 201247159 In addition, in the vacuum cleaner 1, 'the carbon fiber-containing resin is applied to the outer tube main body and the inner tube main body 21, but the carbon fiber-containing resin may be applied to the outer tube main body 11 and the inner tube main body 21, for example. The members of the vacuum cleaner 1 constituting a wheel or the like. Further, as described above, the carbon fiber-containing resin is also applied to the member constituting at least a part (i.e., all or a part of) of the cleaner body 2.
