Abstract
本發明揭示一種電池操作之吹風機,其包含一電池管理及控制模組以控制如何高效率乾燥一使用者之頭髮,同時維持電池之健康及電量。
Description
本發明大體上係關於手持電動吹風機之領域,且具體而言,本發明係關於一種電池操作之手持吹風機。
一般而言,吹風機(亦被稱為「吹乾機」)係眾所周知的。典型手持吹風機使周圍空氣或熱空氣吹過潮濕頭髮以加速水汽蒸發以藉此使頭髮比自我乾燥快地乾燥。典型吹風機由來自電網之電供電,即,其幾乎總是***至一壁式插座中來獲取電力。典型吹風機包含兩個關鍵組件:一風扇及風扇下游之一加熱元件,加熱元件在空氣由風扇吹過時選擇性加熱空氣。首個手持家用吹風機在20世紀上半葉引入,且在近100年間僅有略微改變。
可依諸多不同方式量測吹風機效能,但最普通量測包含空氣流速、空氣離開吹風機時之速度及氣溫相對於周圍氣溫之升高程度。
既有吹風機包含一風扇及至少一電熱線圈。電熱線圈透過電阻加熱之程序來產生熱。通過加熱元件之電流受一線圈抵抗阻擋以導致產生熱。電阻加熱元件通常由可為筆直、盤繞或形成為任何其他適合形狀之電線或條帶製成。電阻加熱元件需要大量電流來產生足以乾燥頭髮之熱。因此,使用電阻加熱元件之吹風機歷來不太適於由電池供電。
典型吹風機亦包含允許一使用者控制吹風機之基本功能之開關。例如,典型吹風機可包含「高」「低」及「關閉」之熱設定及「高」及「低」之風扇設定。上述基本設定適合於自電網汲取電之吹風機,且從維持電池電量之角度看,至今沒人願意更好地最佳化吹風機之效能。
直至現在,能夠在一足夠時段內產生足夠電力(電壓×電流)以實現可靠頭髮乾燥效能之電池極其笨重、龐大及昂貴。而既有吹風機儘管輕質但面臨繫鏈至一電源插座之問題。此外,一使用者在乾燥其頭髮時必須在其頭部周圍不斷移動吹風機,且電源線通常會成為一麻煩。
因而,需要一種電池操作之吹風機,其包含一電池管理系統以允許吹風機高效率乾燥頭髮,同時以一輕質便宜封裝維持一最大電池電量。
本發明係關於一種電池操作之吹風機。該吹風機具有容納該吹風機之所有組件之一外殼。包含至少一電池單元之一電池組包含於該外殼中且電連接至一電池管理及控制模組。該吹風機亦包含至少一開關以控制該吹風機之操作。一加熱總成安置於該外殼內且包含附接至一電動馬達之一風扇。該加熱總成亦包含至少一加熱元件。該馬達由來自該電池組之電流驅動且轉動該風扇,該風扇將周圍空氣吸入至一入口中且透過一出口排出空氣。該加熱元件經定位使得通過該加熱總成之空氣可加熱至高於周圍氣溫之一溫度。該電池管理及控制模組電連接至該加熱總成且調整自該電池組輸送至該風扇及該加熱元件之電流量以最佳化該吹風機之乾燥效能,同時維持該電池組之電量及健康。
熟習技術者應瞭解,本發明之一或多個態樣可滿足特定目的,而一或多個其他態樣可導致其他特定目的。將在[發明內容]及所揭示實施例之描述中明白本發明之其他目的、特徵、益處及優點,且熟習技術者將易於明白本發明之其他目的、特徵、益處及優點。將自結合附圖之上文及自其得出之所有合理推論明白此等目的、特徵、益處及優點。
相關申請案之交叉參考
本申請案基於2017年11月10日申請之美國臨時專利申請案第62/584,528號且主張該案之優先權,該案之全文以引用的方式併入本文中用於所有目的。
現參考圖式,本發明提供一電池操作之吹風機10。吹風機10包含圍封吹風機之所有組件之一主外殼20。圖1至圖2展示靜置於一選用儲存托架12中之吹風機10,儲存托架12在吹風機不使用時對其提供支撐以允許吹風機佔用最少櫃台空間量。在一些實施例中,儲存托架12亦可在吹風機儲存於儲存托架中時向吹風機10提供電力。
吹風機10包含圍封於主外殼20中以使吹風機能夠運轉之三個子系統:(1)一電池組16、(2)一電池管理及控制模組40及(3)一加熱總成50。如圖3之分解圖中所展示,主外殼20界定圍封吹風機10之所有組件之一封閉體。一般而言,電池組16定位於主外殼20之一底部區段32中。在所展示之實施例中,電池組16之部分亦定位於亦包含控制開關44及一電池指示器38之一中部區段42中。加熱總成50定位於主外殼20之一頂部區段52中。加熱總成50包含至少一加熱元件54、至少一風扇56及下文將詳細描述之其他組件。在所展示之實施例中,電池管理及控制模組40實質上安置於頂部區段52與中部區段42之間。在所展示之實施例中,電池管理及控制模組40包括產生頂部區段52與中部區段42之間的一實體障壁之一印刷電路板。儘管在本實施例中電池管理及控制模組40產生頂部區段52與中部區段42之間的一實體障壁,但可在不背離本發明之情況下代以使用分離頂部區段及中部區段之其他構件。在一些實施例中,亦可期望導引空氣通過中部區段42及底部區段32以提高電池效能或用於任何其他目的。
繼續圖3,主外殼20包含一基座22、一出口25 (參閱圖1)、一出口蓋24、一光環26、一出口格柵28、一擋環30及一後蓋33。亦展示可包覆模製至後蓋33上或依其他方式附接至後蓋之一選用夾具34。在所展示之實施例中,夾具34由聚矽氧製成,但可在不背離本發明之情況下使用任何適合材料。夾具34提供有助於一使用者尤其使用濕手緊緊握持吹風機10之一防滑表面。一撓性開關蓋36亦附接至後蓋33。在所展示之實施例中,開關蓋36由一單件撓性材料製成。在不背離本發明之情況下,替代實施例可包含不同開關蓋或開關組態。在所展示之實施例中,一電池指示器38定位於撓性開關蓋36下方(參閱圖14)。當然,在不背離本發明之情況下,電池指示器38可定位於任何其他適合位置處。電池指示器38顯示電池組16之電量。在不背離本發明之情況下,電池指示器38可依任何適合方式顯示電量。例如,在一些實施例中,電池指示器38可根據電池是否在充電或電池電量是否較低來改變色彩。在其他實施例中,電池指示器38可由根據電量來選擇性照明之多個LED組成。
現轉至圖4至圖5,其等展示電池操作之吹風機10之內部組件之封裝。如圖中所展示,加熱總成50包含於頂部區段52內。控制開關44及電池組16之部分包含於中部區段42中。電池管理及控制模組40包含於頂部區段52與中部區段42之間。最後,電池組16之部分亦包含於底部區段32中。
圖6係展示光環26相對於出口25及擋環30之定位的一詳細截面圖。在所展示之實施例中,擋環30卡扣配合至出口25上,但可在不背離本發明之情況下使用任何適合附接構件。光環26包含圍繞環分佈之複數個發光二極體(LED) 25。光環26可在電池操作之吹風機操作時或任何其他預計時間選擇性照明。在一些實施例中,LED 25能夠產生各種所要色彩且亦能夠選擇性閃光或否則依任何所要組態照明。在一較佳實施例中,光環26可在吹風機10操作且加熱空氣時發出紅光。
現轉至圖7至圖11,其等展示一加熱總成50之一實施例。加熱總成50包含一加熱元件54、一風扇56、風扇外殼58、導風管60、導風管支撐導件62、進口64及一馬達66。加熱總成50安置於主外殼20之頂部區段52內。在所展示之實施例中,加熱元件54係一電阻加熱線圈,但可在不背離本發明之情況下使用任何適合加熱元件。馬達66係一無刷三相馬達,其係一非常節能馬達,具有比其他馬達小之振動,且可在0至100%之間精確調變馬達之速度以視需要最佳化效能及能量消耗。
當空氣移動通過風扇56時,風扇在氣流中誘發漩渦(亦稱為渦流)。漩渦無法提高風扇56之效能,但其消耗能量。接著,期望在空氣通過風扇56之後去除空氣漩渦,因為藉此提高風扇之效率。為去除流動漩渦,風扇外殼58及導風管60中包含複數個定子葉片57。定子葉片57導引空氣離開風扇56且將其導引向加熱元件54。除定子葉片57之外,導風管60亦包含進一步防止空氣打旋通過導風管60之導風管支撐導件62。在一些實施例中,可期望僅具有定子葉片57而無導風管支撐件62,或反之亦然。此外,在不背離本發明之情況下,替代實施例可去除定子葉片57及導風管支撐導件62兩者。
在所展示之實施例中,電池管理及控制模組40定位於電池組16與加熱總成50之間。電池管理及控制模組40包含至少一微處理器46及一儲存裝置48。電池管理及控制模組40包含一電池管理系統68 (BMS),其平衡電池單元18之間的電壓且控制電池組16之充電及放電。另外,BMS 68持續量測各電池單元18之電壓。為達成所要平衡,BMS 68經由策略性放置於整個電池組16中之複數個溫度感測器70來監測各電池單元18之溫度。BMS 68取得由溫度感測器70提供之溫度資訊,且結合來自各單元之電壓量測來從電量狀態及健康狀態方面判定電池組16之狀況。電量狀態量測為一百分比(0至100%),而健康狀態量測電池組16相較於其起始壽命狀況之可恢復容量。眾所周知,在此項技術中,一電池維持一電量之能力隨時間降級。BMS 68在決定在任何給定時間釋放或充入多少安全可允許電流之前分析電量狀態及健康狀態資訊以確保電池組16保持於其降級限度及/或預期使用壽命內。
若電壓在電池單元18之間變動,則BMS藉由控制跨任何給定電池單元之放電路徑以洩放額外電量來執行一平衡功能。藉由持續執行上述平衡功能,BMS 68確保電池單元18在電池組16之整個壽命期間保持平衡。
除上述平衡電池單元18之外,BMS 68亦控制電池組16之充電及放電以使其依一受控及安全方式完成。電池組16及類似電池之充電及放電存在諸多安全考量。例如,電池組16之不受控充電會導致一或多個電池單元18之過電壓狀況,其在極端情況中會導致過熱或火災。另一方面,電池組16之不受控放電亦有問題。電池組16之不受控放電會導致一欠電壓狀況,其本身並無危險。然而,若一使用者試圖對一欠電壓電池單元18充電,則其會導致電池組16過早降級、過熱或火災。為防止此等不安全狀況,BMS 68持續監測電池單元18之電壓且包含在電池單元18及電池組16中出現過電壓及欠電壓兩種狀況時切斷電壓。
在吹風機10之一些實施例中,BMS 68「知道」電池組16中還剩多少能量且可調整及修改吹風機之加熱及吹風型態以確保吹風機基於電池組中之剩餘電量來最佳運行。當然,BMS 68可在不背離本發明之情況下依任何其他所要方式調整吹風機10之效能。
圖12及圖13更詳細展示電池組16。在所展示之實施例中,電池組16係包括八個(8個)個別電池單元18之一可再充電鋰離子電池。電池組16電連接至電池管理及控制模組40,電池管理及控制模組40控制如何自電池組16汲取電及如何對電池組充電。當然,在不背離本發明之情況下,電池組16之替代實施例可包含呈任何適合組態之更多或更少電池單元18且亦可使用任何適合電池類型。
各電池單元18包含自各電池單元之一端延伸之兩個端子19。在所展示之實施例中,端子19延伸穿過一端子固結板74中之端子槽72。在所展示之實施例中,端子固結板74係一印刷電路板,但可在不背離本發明之情況下使用任何適合基板。端子19與端子槽72電接觸,端子槽72允許歸因於電池單元18膨脹或收縮而移動端子19。端子固結板74將電池單元18電組合成電池組16,其最少化電池組16與BMS 68之間的所需連接。在所展示之實施例中,電池組16包含彼此電連接之兩個端子固結板74、75。在所展示之實施例中,電池組16電連接至BMS 68。最後,電池組16進一步包含一充電口76,一使用者可視需要將一充電線78***至充電口76中以對電池組充電。充電口76可為包含(但不限於)一USB口之任何適合口。
在一替代實施例中,電池組16能夠無線或感應充電以無需充電口76。在又一替代實施例中,電池操作之吹風機可包含至少一太陽能單元,其將使用太陽能來對電池組16充電。若在無法接入一充電源之地方(諸如一露營地)使用吹風機10,則太陽能充電將特別有利。在此一替代實施例中,亦可依類似於此項技術中所熟知之其他附加電池組之一方式使用電池組16來給其他裝置(諸如一使用者之行動電話)提供電力。
除平衡電池單元18之電量之外,電池管理及控制模組40亦可依各種方式最佳化電池操作之吹風機10之效能。電池管理及控制模組40能夠依任何期望方式控制風扇速度及加熱輸出。最重要的是,電池管理及控制模組40最佳化吹風機10之效能,使得使用者將滿意吹乾效能。在一所要乾燥型態中,在乾燥循環開始時施加最高熱,因為此時頭髮通常最濕。隨著乾燥循環繼續,熱輸出可減少且不使效能降級,因為頭髮不同樣濕了且因為降低溫度將避免損壞頭髮。可將額外乾燥型態儲存於儲存裝置48上。此等額外乾燥型態可預載至儲存裝置48上,可由電池管理及控制模組40藉由分析一使用者如何使用吹風機10來「知悉」,可由一使用者程式化,或可在不背離本發明之情況下由任何其他所要構件產生。
電池管理及控制模組40係實現使用電池來對一吹風機供電所需之一組件。因此,一智慧型控制模組之存在提供使用一吹風機來完成各項任務之可能性。例如,在電池操作之吹風機10之一些實施例中,溫度感測器80 (參閱圖3及圖5)可包含於進口64附近及出口25附近。溫度感測器80將量測室內環境溫度且能夠比較該資料與離開吹風機10之空氣之溫度。根據進口64及出口25處之氣溫差,電池管理及控制模組40可最佳化通過加熱元件54之電流量或可視需要調整風扇56之速度。
電池操作之吹風機10可包含額外環境感測器,其包含(但不限於)濕度感測器、用於量測頭髮或皮膚溫度之一紅外線溫度計或任何其他所要感測器。此外,額外組件可包含於吹風機10中且連接至電池管理及控制模組40。例如,一攝影機可包含於出口25附近,攝影機將允許電池管理及控制模組40分析及知悉使用者之頭髮類型、長度等等且自動調整風扇速度或熱輸出以最高效率乾燥使用者之頭髮。吹風機10亦可包含至少一Bluetooth無線電82、wi-fi天線84或將吹風機連接至網際網路或一連接網際網路裝置(諸如一智慧型電話或平板電腦)之其他構件。一旦吹風機10連接至網際網路或一智慧型電話、平板電腦或其他裝置,則電池管理及控制模組40可基於任何數目個外部因數來控制吹風機。極端而言,吹風機10可基於當日時間、位置、當地天氣等等來最佳化效能。此外,若使用者在其家中具有諸如一恆溫器之一連接裝置,則吹風機10可自恆溫器獲得溫度及/或濕度資料以判定乾燥使用者之頭髮之最佳風扇速度及溫度。
在電池操作之吹風機10之一些實施例中,一麥克風及揚聲器可包含於外殼20中。麥克風及揚聲器可用於任何目的,其包含(但不限於)產生聲音以積極消除由吹風機10產生之噪音。為消除由吹風機10產生之噪音,麥克風拾取由吹風機產生之噪音。接著,電池管理及控制模組40產生與由吹風機產生之噪音180°異相之一消音波。消音波有效消除吹風機10之噪音以極大改良使用者體驗。除使用揚聲器來產生消音波之外,亦可使用揚聲器來播放音樂或產生任何其他悅耳聲音。
現轉至圖15至圖18,其等展示根據本發明之一電池操作之吹風機200之一替代實施例。除電池操作之吹風機200包含使用至少一帕耳帖(peltier)裝置212來加熱空氣之一加熱總成210而非一電阻加熱器之外,電池操作之吹風機200在諸多方面類似於上述實施例。帕耳帖裝置(亦稱為熱電產生器)在此項技術中係眾所周知的。帕耳帖裝置包括交替n型及p型半導體之一陣列。元件陣列電串聯及熱並聯地焊接於兩個陶瓷板之間。當一電流自n型至p型通過一或多個元件對時,接面(「冷側」)處之溫度降低以導致自環境吸收熱。該熱藉由電子傳輸來沿元件載運且隨著電子自一高能狀態移動至低能狀態而釋放於對置(「熱」)側上。典型單級帕耳帖裝置能夠產生約70攝氏度(158華氏度)之熱側與冷側之間的溫差。
在圖15至圖18所展示之實施例中,帕耳帖裝置212各具有一熱側214及一冷側216。複數個散熱器218熱連接至帕耳帖裝置212。在加熱總成210上游,一馬達220附接至使空氣吹過加熱總成之一風扇221。在加熱總成210之緊鄰下游,一出口導風管222匯集已通過加熱總成210之熱空氣輸送朝向及離開出口格柵28。圍繞加熱總成210通過之空氣在通過散熱器218時冷卻。冷空氣無法透過出口格柵28而離開吹風機200,因為其由出口導風管222阻擋。確切而言,冷空氣被導引至別處且可導引向電池組16以促進電池組冷卻。當然,可在不背離本發明之情況下使用帕耳帖裝置及散熱器之替代組態。
