Description
本發明係關於吸塵器的技術領域，尤指應用於吸塵器之中的一種地板材質識別裝置。The invention relates to the technical field of vacuum cleaners, in particular to a floor material identification device applied to vacuum cleaners.
對於現代的家庭而言，吸塵器已成為不可或缺的一種家用電器。圖1顯示習知的一種吸塵器的立體圖，如圖1所示，習知的吸塵器1a的組成主要包括：一機體11a、一延伸連接器12a、以及一塵吸單元13a，其中，該塵吸單元13a包含用以接合該延伸連接器12a的一連接管131a以及與該連接管131a相接的一吸頭132a。值得說明的是，為了滿足家庭的各種吸塵需求，家電製造商開發了多種類型的吸頭132a，包括：具有地板刷(Bare floor brush)的吸頭、具有風動式滾輪刷(Air driven rotating brush)的吸頭、具有電動式滾輪刷(Electrically-driven rotating brush)的吸頭、以及吸嘴式吸頭等。For modern families, vacuum cleaners have become an indispensable household appliance. Fig. 1 shows a perspective view of a known vacuum cleaner. As shown in Fig. 1, the composition of a known
圖2顯示圖1之吸塵器1a所搭載的具有電動式滾輪刷之吸頭132a的立體圖。如圖2所示，所謂具有電動式滾輪刷的吸頭係指內部設有一滾輪刷1321a和一滾輪驅動馬達1322a的吸頭132a。使用吸塵器1a進行地板清掃時，滾輪驅動馬達1322a受到一驅動電流的控制而運轉，從而帶動滾輪刷1321a轉動，藉此方式提升吸塵器1a的吸塵效率。然而，實務經驗指出，具有電動式滾輪刷之吸頭132a較適合使用於硬質地板，例如：磁磚地板與木質地板。如圖2與圖3所示，當具有電動式滾輪刷之吸頭132a於鋪設有長毛地毯或短毛地毯的軟質地板上移動時，受到滾輪驅動馬達1322a驅動而不停轉動的滾輪刷1321a會將地毯的軟毛收捲在其輪身之上，最終導致滾輪刷1321a卡死且吸頭132a無法移動。FIG. 2 shows a perspective view of a
值得說明的是，家電製造商已經開發出具地板識別功能的吸塵器，例如台灣專利號I698214揭示了一種具地板檢知功能的吸塵器，其利用將超音波感測器或光學感測器作為一地板識別感測器而被整合在如圖2所示之吸頭132a上，從而實現地板檢知之功能。依據台灣專利號I698214的揭示內容，所述吸頭132a還包括一高度調整單元。當所述地板識別感測器偵測到具有電動式滾輪刷之吸頭132a於鋪設有長毛地毯或短毛地毯的軟質地板上移動時，控制晶片即控制該高度調整單元提升吸頭132a的高度，藉此方式避免地毯的軟毛被滾輪刷1321a捲住。同時，控制晶片還同步調整吸塵器1a之吸塵馬達(即，真空馬達)的動力，藉以調降吸力。It is worth noting that home appliance manufacturers have developed vacuum cleaners with floor recognition functions. For example, Taiwan Patent No. I698214 discloses a vacuum cleaner with floor detection functions, which utilizes an ultrasonic sensor or an optical sensor as a floor recognition function. The sensor is integrated on the
雖然家電製造商已經開發出具地板識別功能的吸塵器1a，然而其將地板識別感測器和高度調整單元整合在吸頭132a上，導致吸塵器1a的製造成本提高且售價昂貴。另一方面，所述具地板識別功能的吸塵器1a僅具有依據地板材質調整吸塵馬達的吸力之功能，並無依據地板材質調整吸頭132a內的滾輪驅動馬達1322a之功能。在此情況下，即使高度調整單元提升了吸頭132a的高度，滾輪驅動馬達1322a仍會持續地驅動滾輪刷1321a轉動，最終地毯的軟毛還是會被滾輪刷1321a捲住，從而導致滾輪刷1321a卡死且吸頭132a無法移動。Although home appliance manufacturers have developed the
由前述說明可知，習知的具地板識別功能的吸塵器1a仍具有加以改善的空間。有鑑於此，本案之發明人係極力加以研究發明，而終於研發完成一種地板材質識別裝置，其可整合在具有電動式滾輪刷的吸頭之中。It can be known from the foregoing description that the

As shown in Figure 5 and Figure 6, the floor
更詳細地說明，該第一信號處理單元202耦接該第一電流感測單元21以接收第一電流感測信號(或第二電流感測信號)，從而將該第一電流感測信號轉換成一第一信號(或一第二信號)。在一實施例中，該第一信號處理單元202為一類比數位轉換器，因此該第一信號與該第二信號皆為一數位信號。另一方面，該控制單元200耦接該參數儲存單元201與該第一信號處理單元202，且自該第一信號處理單元202接收所述第一信號(或第二信號)。In more detail, the first
圖7顯示該參數儲存單元所儲存的複數個參考數值之示意圖。並且，圖8A、圖8B與圖8C分別顯示該吸頭132在一硬質地板、一鋪設短毛地毯之地板與一鋪設長毛地毯之地板上移動的示意圖。請參考圖8A與圖7的深灰色點狀曲線資料，在該第一信號的一第一準位值落在該基礎準位值和該第一臨界準位值之間的一第一區間(Zone1)的情況下，該控制單元200判斷該吸頭132係位於一硬質地板3A上。應可理解，所述基礎準位值為滾輪驅動馬達1322未運轉之時的驅動電流(數位)值，因此可視為0。當然，在可行的實施例中，所述基礎準位值也可以不為0，而是一個基準參考值。FIG. 7 shows a schematic diagram of a plurality of reference values stored in the parameter storage unit. 8A, 8B and 8C respectively show the schematic diagrams of the
請繼續參考圖8B與圖7的深灰色點狀曲線資料，在所述第一準位值落在該第一臨界準位值和該第二臨界準位值之間的一第二區間(Zone2)的情況下，該控制單元200判斷該吸頭132係位於一鋪設短毛地毯之地板3B上。再者，如圖8C與圖7的深灰色點狀曲線資料所示，當所述第一準位值落在該第二臨界準位值和該第三臨界準位值之間的一第三區間(Zone3)之時，該控制單元200判斷該吸頭132係位於一鋪設長毛地毯之地板3C上。Please continue to refer to the dark gray dotted curve data in FIG. 8B and FIG. 7, where the first level value falls within a second interval (Zone2 ), the
應可理解，當吸頭123沿著第一方向(如前進方向)在硬質地板3A上移動且繼續地移動至一鋪設短毛地毯之地板3B之後，控制單元200在利用負載變化(如圖7所示之滾輪驅動馬達1322之驅動電流變化)完成地板材質的識別後，其可調控用以控制該滾輪驅動馬達1322之驅動電流的大小，從而控制該滾輪驅動馬達1322的轉速及/或扭矩。在一示範性實施例中，控制單元200產生具一指定佔空比(Duty cycle)的一PWM信號傳送至耦接於該驅動電流和該滾輪驅動馬達1322之間的一開關元件(如IGBT或MOSFET)，進而調控該開關元件的開/關頻率，藉此方式達到控制該滾輪驅動馬達1322的轉速及/或扭矩之目的。It should be understood that when the suction head 123 moves along the first direction (such as the forward direction) on the
如圖5與圖6所示，本發明之地板材質識別裝置2，更包括整合在該吸頭132之中的一方向感測器22，其用以感測該吸頭132之一前進方向或一後退方向。在一實施例中，該方向感測器22係透過感測所述移動輔輪1323的一轉動方向而完成該前進方向或該後退方向之感測。舉例而言，若前述之第一方向為前進方向，則所述後退方向即為一第二方向。如圖7所示，深灰色的曲線資料係在吸頭132沿著前進方向(第一方向)移動時所測得之滾輪驅動馬達1322的驅動電流的數位信號(第一信號)，而黑色的曲線資料係在吸頭132沿著後對方向(第二方向)移動時所測得之滾輪驅動馬達1322的驅動電流的數位信號(第二信號)。因此，可以理解的是，在該第一方向為所述後退方向的情況下，一第二方向即為所述前進方向。As shown in Figures 5 and 6, the floor
承上述說明，儲存在該參數儲存單元201之中的該複數個參考數值係更包括一第一參考差值、一第二參考差值與一第三參考差值。並且，該信號處理及控制模組20更包括：耦接該控制單元200與該方向感測器22的一第二信號處理單元203，用以接收一移動方向感測信號，且將該移動方向感測信號轉換成一移動方向信號。在一示範性實施例中，依據該方向感測器22之種類，該第二信號處理單元203可為一類比數位轉換器或一數位信號處理器。過前述說明應可理解，在該移動方向信號指出該吸塵器1係沿著一前進方向(第一方向)移動的情況下，該第一信號處理單元202自該第一電流感測單元21接收一第一電流感測信號，且該控制單元200自該第一信號處理單元202接收一第一信號(數位信號)。並且，在該移動方向信號指出該吸塵器1係沿著一後退方向(第二方向)移動的情況下，該第一信號處理單元202自該第一電流感測單元21接收一第二電流感測信號，且該控制單元200自該第一信號處理單元202接收一第二信號(數位信號)。According to the above description, the plurality of reference values stored in the
補充說明的是，該控制單元200還具有一過載限制功能，用以於該第一信號的該第一準位值超過一過載限制準位之時停止該滾輪驅動馬達1322之運轉。It is added that the
依此設計，如圖7所示，在該第二信號的一第二準位值和該第一信號的該第一準位值之間的一準位差值低於所述第一參考差值的情況下，該控制單元200判斷該吸頭132係位於所述硬質地板3A上。並且，在該準位差值大於該第一參考差值且低於所述第二參考差值的情況下，該控制單元200判斷該吸頭132係位於所述鋪設短毛地毯之地板3B上。進一步地，在該準位差值大於該第二參考差值且低於所述第三參考差值的情況下，該控制單元200判斷該吸頭132係位於所述鋪設長毛地毯之地板3C上。According to this design, as shown in FIG. 7, a level difference between a second level value of the second signal and the first level value of the first signal is lower than the first reference difference value, the
使用過吸塵器1進行地板清掃工作的用戶必然知道，在地板清掃的過程中，吸頭132不會僅限於在同一種地板(如硬質地板3A)上移動。當然，當吸頭132位於同一地板之上時，控制該滾輪驅動馬達1322的驅動電流的電流值必為定值，原因在於該滾輪驅動馬達1322負載固定，是以電流值也為定值。因此，可以想像的是，當吸頭132自硬質地板3A移動至鋪設短毛地毯之地板3B上後，該滾輪驅動馬達1322的負載有所變動，電流值因而改變。Users who have used the
故而，本發明進一步地令儲存在該參數儲存單元201之中的該複數個參考數值更包括一第一參考準位變化量與一第二參考準位變化量。如此設計，如圖7所示，當該吸頭132沿著所述第一方向(前進方向)移動且落於所述第一區間(Zone1)的該第一準位值突然具有大於所述第一參考準位變化量的準位變化時，該控制單元200判斷該吸頭132係自所述硬質地板3A移動至所述鋪設短毛地毯之地板3B。進一步地，當該吸頭132沿著所述第一方向(前進方向)移動且落於所述第二區間(Zone2)的該第一準位值突然具有大於所述第二參考準位變化量之準位變化時，該控制單元200判斷該吸頭132係自所述鋪設短毛地毯之地板3B移動至所述鋪設長毛地毯之地板3C上。Therefore, the present invention further makes the plurality of reference values stored in the
同理可推，當吸頭132自鋪設地毯的地板移動至一硬地面之上以後，該滾輪驅動馬達1322的負載也會有所變動，電流值因而改變。故而，本發明進一步地令儲存在該參數儲存單元201之中的該複數個參考數值更包括一第三參考準位變化量與一第四參考準位變化量。In the same way, when the
依據本發明之設計，如圖7所示，當該吸頭132沿著所述第一方向(前進方向)移動且落於所述第三區間(Zone3)的該第一準位值突然具有大於所述第三參考準位變化量之準位變化時，該控制單元200判斷該吸頭132係自所述鋪設長毛地毯之地板3C移動至所述鋪設短毛地毯之地板3B上。並且，當該吸頭132沿著所述第一方向(前進方向)移動且落於所述第二區間(Zone2)的該第一準位值突然具有大於所述第四參考準位變化量之準位變化時，該控制單元200判斷該吸頭132係自所述鋪設短毛地毯之地板3B移動至所述硬質地板3A。According to the design of the present invention, as shown in FIG. 7, when the
並且，如圖6所示，本發明之地板材質識別裝置2可更包括：耦接設於該機體11內的一吸塵馬達111(即，真空馬達)的一第二電流感測單元23，用於感測控制該吸塵馬達111運轉的一驅動電流，從而輸出一驅動電流感測信號。同時，該信號處理及控制模組20更包括：耦接該控制單元200與該第二電流感測單元23的一第三信號處理單元204，用以接收所述驅動電流感測信號，且將該驅動電流感測信號號轉換成一驅動電流信號。在一實施例中，該第三信號處理單元204為一類比數位轉換器，因此該驅動電流信號為一數位信號。And, as shown in FIG. 6 , the floor
應可理解，當吸頭132沿著第一方向(如前進方向)在硬質地板3A上移動且繼續地移動至一鋪設短毛地毯之地板3B之後，控制單元200在利用負載變化(如圖7所示之滾輪驅動馬達1322之驅動電流變化)完成地板材質的識別後，其可調控用以控制該吸塵馬達111之驅動電流的大小，從而控制該吸塵馬達111的轉速及/或扭矩。在一示範性實施例中，控制單元200產生具一指定佔空比(Duty cycle)的一PWM信號傳送至耦接於該驅動電流和該吸塵馬達111之間的一開關元件(如IGBT或MOSFET)，進而調控該開關元件的開/關頻率，藉此方式達到控制該吸塵馬達111的轉速及/或扭矩之目的。It should be understood that when the
圖9顯示圖4之吸塵器1所搭載的具有電動式滾輪刷之吸頭132的第二立體圖。如圖9所示，在可行的實施例中，所述吸頭132進一步包括一吸風量調整單元133。對應地，如圖6所示，該信號處理及控制模組20之控制單元200耦接該吸風量調整單元133。如此設計，當該吸頭132自硬質地板3A移動至鋪設短毛地毯之地板3B或鋪設長毛地毯之地板3C之後，該控制單元200在利用負載變化完成地板材質的識別後，其可控制該吸風量調整單元133之一風量調整口1331的開口率，藉此方式從而調整該吸頭132至該延伸連接器12之間的一氣流量。FIG. 9 shows a second perspective view of the
如此，上述係已完整且清楚地說明本發明之一種地板材質識別裝置、電動式滾輪地刷、及吸塵器。必須加以強調的是，上述之詳細說明係針對本發明可行實施例之具體說明，惟該實施例並非用以限制本發明之專利範圍，凡未脫離本發明技藝精神所為之等效實施或變更，均應包含於本案之專利範圍中。Thus, the above has completely and clearly described a floor material identification device, an electric roller floor brush, and a vacuum cleaner of the present invention. It must be emphasized that the above detailed description is a specific description of a feasible embodiment of the present invention, but the embodiment is not used to limit the patent scope of the present invention, any equivalent implementation or modification that does not depart from the technical spirit of the present invention, All should be included in the patent scope of this case.
