Description
本发明的实施方式涉及电吸尘器。 Embodiments of the invention relate to an electric vacuum cleaner.
眾所周知的是離心分離方式的電吸塵器，其包括：圓筒形狀的容器主體；及過濾濾器，收納在容器主體內而在與容器主體之間形成環狀的分離室。該現有的電吸塵器通過在分離室內產生的回旋流而使空氣與灰塵離心分離。過濾濾器較容器主體短，容器主體與過濾濾器的長度的差分為在容器主體內蓄積灰塵的集塵室。分離室與集塵室在成為回旋流的外緣的容器主體的內周面附近大致無分界線地連續連接。另一方面，分離室與集塵室在靠近成為回旋流的內緣的容器主體的中心線的側以凸緣形狀或杯(cup)形狀的隔離部隔開。 A centrifugal separator type electric vacuum cleaner is known which includes a cylindrical container body and a filter filter which is housed in the container body and forms an annular separation chamber between the container body and the container body. The existing electric vacuum cleaner centrifugally separates air from dust by a swirling flow generated in the separation chamber. The filter is shorter than the container body, and the difference between the length of the container body and the filter filter is a dust collecting chamber in which the dust accumulates in the container body. The separation chamber and the dust collecting chamber are continuously connected substantially without a boundary line in the vicinity of the inner peripheral surface of the container main body which is the outer edge of the swirling flow. On the other hand, the separation chamber and the dust collecting chamber are separated by a flange-shaped or cup-shaped partition portion on the side close to the center line of the container main body which becomes the inner edge of the swirling flow.

筒狀的容器主體通過以沿著其內周面的方式引導空氣而在分離室內產生回旋流。向容器主體內引導空氣的入口，設置在筒狀側壁部的任一部位而成為回旋流的起點。回旋流并不是在容器主體內穩定地通過固定位置，而是根據電動送風機的運轉輸出的變化、從入口流入的空氣流量的變化、空氣中所含的灰塵量的變化等而不停地變化。 The cylindrical container body generates a swirling flow in the separation chamber by guiding the air along the inner circumferential surface thereof. The inlet for guiding the air into the container body is provided at any portion of the cylindrical side wall portion to be the starting point of the swirling flow. The swirling flow does not continuously pass through the fixed position in the container body, but changes continuously depending on a change in the operation output of the electric blower, a change in the flow rate of the air flowing in from the inlet, a change in the amount of dust contained in the air, and the like.
然而，與灰塵一同向集塵室流入的空氣、即回旋流的下游側，在容器主體的圓周方向上通常在設置有入口的相位的附近，與從入口新流入的空氣、即回旋流的上流側合流的傾向强。 However, the air flowing into the dust collecting chamber together with the dust, that is, the downstream side of the swirling flow, is generally in the circumferential direction of the container main body in the vicinity of the phase in which the inlet is provided, and the air newly flowing from the inlet, that is, the upward flow of the swirling flow. The tendency to merge sideways is strong.
在該回旋流的合流部位，具有灰塵易於停滯的傾向，有時會產生灰塵的大的塊。該灰塵的大的塊有時夾在回旋流的上流側與下游側合流的位置、且連接分離室與集塵室的容器主體與隔離部之間的間隙中。 At the junction of the swirling flow, dust tends to stagnate, and a large block of dust may be generated. The large block of the dust is sometimes sandwiched between the upstream side and the downstream side of the swirling flow, and is connected to the gap between the separation chamber and the container body and the partition of the dust collecting chamber.
一旦在容器主體與隔離部之間的間隙中夾有灰塵，則通過回旋流從分離室運送至集塵室的灰塵，以相對於夾在容器主體與隔離部之間的間隙中的灰塵而向回旋流的上流側積層的方式不斷向圓周方向蓄積。 Once the dust is caught in the gap between the container body and the partition, the dust that is transported from the separation chamber to the dust collecting chamber by the swirling flow is directed to the dust in the gap between the container body and the partition. The manner in which the upstream side of the swirling flow is accumulated continuously accumulates in the circumferential direction.
而且，有時夾在容器主體與隔離部之間的間隙中的灰塵變得越大，越阻礙欲從分離室流入至集塵室的回旋流的氣流，或 一旦流入至集塵室的回旋流越過夾在容器主體與隔離部之間的間隙中的灰塵而向分離室側回吹，就會使電吸塵器的分離性能降低。 Moreover, sometimes the dust which is caught in the gap between the container main body and the partition becomes larger, and the more the airflow of the swirling flow which is to flow from the separation chamber to the dust collecting chamber is hindered, or When the swirling flow that has flowed into the dust collecting chamber passes back the dust that has been caught in the gap between the container main body and the partition portion and is blown back toward the separating chamber side, the separation performance of the electric vacuum cleaner is lowered.
由此，本發明的目的在於獲得一種灰塵不易滯留在圓筒形狀的容器主體與隔離部之間的電吸塵器。 Accordingly, an object of the present invention is to obtain an electric vacuum cleaner in which dust is less likely to remain between a cylindrical container body and a partition.
為解决所述課題，本發明的實施方式的電吸塵器包括：圓筒形狀的容器主體；過濾濾器部，呈較所述容器主體短的圓筒形狀而收納在所述容器主體內，在所述過濾濾器部與所述容器主體之間形成環狀的分離室；隔離部，呈直徑較所述過濾濾器部大且外徑較所述容器主體小的形狀，且形成集塵室，所述集塵室是設置成與鄰接於所述過濾濾器部的一端部的所述分離室相互相鄰連通；及旋轉支撑部，以所述容器主體的中心線為旋轉軸而旋轉自如地支撑所述隔離部。 In order to solve the above problems, an electric vacuum cleaner according to an embodiment of the present invention includes a cylindrical container body, and a filter filter portion is housed in a cylindrical shape shorter than the container body and housed in the container body. Forming an annular separation chamber between the filter filter portion and the container body; the partition portion having a diameter larger than the filter filter portion and having a smaller outer diameter than the container body, and forming a dust collecting chamber, the set a dust chamber is disposed adjacent to the separation chamber adjacent to one end portion of the filter filter portion; and a rotation support portion rotatably supporting the isolation with a center line of the container body as a rotation axis unit.
此外，所述電吸塵器包括以所述容器主體的中心線為旋轉軸而旋轉自如地支撑所述過濾濾器部、及所述隔離部的旋轉支撑部。 Further, the electric vacuum cleaner includes a rotation support portion that rotatably supports the filter filter portion and the partition portion with a center line of the container body as a rotation axis.
由此，可獲得灰塵不易滯留在圓筒形狀的容器主體與隔離部之間的電吸塵器。 Thereby, it is possible to obtain an electric vacuum cleaner in which dust does not easily remain between the cylindrical container body and the partition.

其次，對第1實施方式的電吸塵器1的動作進行說明。 Next, the operation of the electric vacuum cleaner 1 of the first embodiment will be described.
此處，首先為與第1實施方式進行比較，而使用圖5(a)~5(c)對包括不相對於容器主體101旋轉的隔離部103的現有的電吸塵器104進行說明。 Here, first, in comparison with the first embodiment, a conventional electric vacuum cleaner 104 including a partition portion 103 that does not rotate with respect to the container body 101 will be described with reference to FIGS. 5(a) to 5(c).
圖5(a)、圖5(b)及圖5(c)是示意性地表示現有的電吸塵器的灰塵分離集塵裝置的橫截面圖。 5(a), 5(b), and 5(c) are cross-sectional views schematically showing a dust separating and dust collecting device of a conventional electric vacuum cleaner.
如圖5(a)所示般，向灰塵分離集塵裝置105流入的空氣成為在過濾濾器106的周圍回旋的回旋流F。該回旋流F不斷向灰塵分離集塵裝置105流入，回旋流F的下游側在設置有入口的相位的附近與新流入的空氣、即回旋流F的上流側的空氣合流後，將氣流的方向改變為向容器主體101的中心線C側。在該回旋流F的合流部位M，具有灰塵易於滯留的傾向。 As shown in FIG. 5( a ), the air that has flowed into the dust separating and dust collecting device 105 is a swirling flow F that swirls around the filter filter 106 . The swirling flow F continuously flows into the dust separating and dust collecting device 105, and the downstream side of the swirling flow F merges with the newly flowing air, that is, the air on the upstream side of the swirling flow F, in the vicinity of the phase in which the inlet is provided, and then the direction of the airflow The change is to the side of the center line C of the container body 101. At the junction M of the swirling flow F, dust tends to stay.
而且，如圖5(b)所示般，存在停滯在合流部位M的灰塵產生灰塵的大的灰塵塊D的情况。該灰塵塊D存在夾在回旋流F的上流側與下游側合流的位置、且連接分離室108與集塵室109的容器主體101與隔離部103之間的間隙中的情况。 Further, as shown in FIG. 5(b), there is a case where a large dust block D that generates dust due to dust that has stopped at the joining portion M exists. The dust block D is sandwiched between the upstream side and the downstream side of the swirling flow F, and is connected to the gap between the separation chamber 108 and the container main body 101 and the partition 103 of the dust collecting chamber 109.
而且，在現有的電吸塵器104中，隔離部103不旋轉，因此如圖5(c)所示般，灰塵塊D一旦夾在容器主體101與隔離部103之間的間隙中，則應通過回旋流F從分離室108運送至集塵室109的灰塵，以相對 於灰塵塊D而向回旋流F的上流側、即容器主體101的圓周方向不斷積層的方式蓄積。 Further, in the conventional electric vacuum cleaner 104, since the partition portion 103 does not rotate, as shown in FIG. 5(c), once the dust block D is caught in the gap between the container body 101 and the partition portion 103, it should be swirled. The flow F is carried from the separation chamber 108 to the dust of the dust collection chamber 109 to The dust block D is accumulated so as to continuously flow on the upstream side of the swirling flow F, that is, in the circumferential direction of the container body 101.
存在如下情况，即夾在容器主體101與隔離部103之間的間隙中的灰塵越大，越阻礙欲從分離室108向集塵室109流入的回旋流F的氣流，或一旦流入至集塵室109的回旋流F越過夾在容器主體101與隔離部103之間的間隙中的灰塵而向分離室108側回吹，就會使分離性能降低。 There is a case where the dust which is caught in the gap between the container main body 101 and the partition portion 103 is larger, the more the flow of the swirling flow F to be flown from the separation chamber 108 to the dust collecting chamber 109 is blocked, or once it flows into the dust collecting The swirling flow F of the chamber 109 is blown back toward the separation chamber 108 side by the dust caught in the gap between the container main body 101 and the partition portion 103, and the separation performance is lowered.
另一方面，圖6(a)、圖6(b)、圖6(c)、及圖6(d)是示意性地表示本發明的第1實施方式的電吸塵器的灰塵分離集塵裝置的橫截面圖。 On the other hand, Fig. 6 (a), Fig. 6 (b), Fig. 6 (c), and Fig. 6 (d) are schematic diagrams showing the dust separating and dust collecting device of the electric vacuum cleaner according to the first embodiment of the present invention. Cross-sectional view.
如圖6(a)所示般，即便為第1實施方式的電吸塵器1，流入至灰塵分離集塵裝置7的空氣也成為在第一過濾濾器部37的周圍回旋的回旋流F。該回旋流F不斷向灰塵分離集塵裝置7流入，回旋流F的下游側在設置有入口的相位的附近與新流入的空氣、即回旋流F的上流側的空氣合流後，將氣流的方向改變為向容器主體35的中心線C側。 As shown in FIG. 6( a ), even in the electric vacuum cleaner 1 of the first embodiment, the air that has flowed into the dust separating and dust collecting device 7 is a swirling flow F that swirls around the first filter unit 37 . The swirling flow F continuously flows into the dust separating and dust collecting device 7, and the downstream side of the swirling flow F merges with the newly flowing air, that is, the air on the upstream side of the swirling flow F, in the vicinity of the phase in which the inlet is provided, and then the direction of the airflow The change is to the side of the center line C of the container body 35.
而且，如圖6(b)所示般，存在停滯在合流部位M的灰塵產生灰塵的大的灰塵塊D的情况。該灰塵塊D存在夾在回旋流F的上流側與下游側合流的位置、且連接分離室51與集塵室52的容器主體35與隔離部38之間的間隙61中的情况。 Further, as shown in FIG. 6(b), there is a case where a large dust block D that generates dust due to dust that has stopped at the joining portion M exists. The dust block D is sandwiched between the upstream side and the downstream side of the swirling flow F, and is connected to the gap 61 between the separation chamber 51 and the container main body 35 of the dust collecting chamber 52 and the partition portion 38.
然而，在第1實施方式的電吸塵器1中，如圖6(c)所示般，即便灰塵塊D夾在間隙61中，也可通過使隔離部38旋轉(圖6(a)~6(d)中，實線箭頭R)而將灰塵塊D向回旋流F的下游側推出。 However, in the electric vacuum cleaner 1 of the first embodiment, as shown in FIG. 6(c), even if the dust block D is sandwiched in the gap 61, the partition portion 38 can be rotated (FIG. 6(a) to 6( In the middle of the d), the solid arrow R) pushes the dust block D toward the downstream side of the swirling flow F.
其次，灰塵塊D如圖6(d)所示般，暴露在從入口流入的回旋 流F的上流側、即流速更快的空氣的氣流中而從間隙61脫離後，再次捲入回旋流中，最終蓄積於集塵室52中。 Secondly, the dust block D is exposed to the swirling flow from the inlet as shown in Fig. 6(d). The upstream side of the flow F, that is, the airflow of the air having a faster flow velocity, is separated from the gap 61, and then re-entangled in the swirling flow, and finally accumulated in the dust collecting chamber 52.
此外，第1實施方式的電吸塵器1中，使隔離部38旋轉，因此除回旋流F以外還可利用隔離部38攪拌集塵室52內的灰塵，因此可實現集塵室52內的灰塵的分布密度的均質化，可消除灰塵的偏置而蓄積更多的灰塵。 Further, in the vacuum cleaner 1 of the first embodiment, since the partition portion 38 is rotated, the dust in the dust collecting chamber 52 can be stirred by the partition portion 38 in addition to the swirling flow F, so that dust in the dust collecting chamber 52 can be realized. The homogenization of the distribution density eliminates the offset of dust and accumulates more dust.
如此，第1本實施方式的電吸塵器1，在容器主體35內包括旋轉自如的隔離部38，因此灰塵不易夾在容器主體35與隔離部38之間的間隙61中。 As described above, the vacuum cleaner 1 of the first embodiment includes the detachable partition portion 38 in the container body 35, so that the dust is less likely to be caught in the gap 61 between the container body 35 and the partition portion 38.
即便假設夾有灰塵，也可利用在容器主體35內產生的回旋流F而使所夾的灰塵脫離并重複努力向集塵室52捕獲，從而均可引導至集塵室52并蓄積於其中。 Even if it is assumed that dust is caught, the swirling flow F generated in the container main body 35 can be detached from the dust and repeatedly caught in the dust collecting chamber 52, and can be guided to the dust collecting chamber 52 and accumulated therein.
由此，電吸塵器1可將所分離的灰塵切實地蓄積於集塵室52中而持續長時間地維持分離性能。 Thereby, the vacuum cleaner 1 can reliably store the separated dust in the dust collecting chamber 52, and maintain the separation performance for a long time.
此外，第1實施方式的電吸塵器1，利用向隔離部38噴附的回旋流F或回旋流F中所含的灰塵使隔離部38旋轉，因此無需使隔離部38旋轉的單獨、追加性的原動機等部件、或用以與回旋流F的流速同步的測定器、或控制系統，從而可抑制零件件數的增加數量而確保可靠性。 In the electric vacuum cleaner 1 of the first embodiment, the partition portion 38 is rotated by the dust contained in the swirling flow F or the swirling flow F sprayed to the partition portion 38. Therefore, it is not necessary to separately or additionally rotate the partition portion 38. A component such as a prime mover or a measuring device or a control system for synchronizing with the flow velocity of the swirling flow F can suppress the increase in the number of parts and ensure reliability.
進而，第1實施方式的電吸塵器1在隔離部38的側壁63外周面包括凹部81，因此可使利用回旋流F或回旋流F中所含的灰塵而產生的隔離部38的驅動轉矩(torque)變大，從而易於使夾在間隙61中的灰塵脫離。 Further, since the vacuum cleaner 1 of the first embodiment includes the concave portion 81 on the outer circumferential surface of the side wall 63 of the partition portion 38, the driving torque of the partition portion 38 due to the dust contained in the swirling flow F or the swirling flow F can be obtained ( The torque) becomes large, so that it is easy to detach the dust caught in the gap 61.
進而此外，第1實施方式的電吸塵器1通過在隔離部38設置翼板83，而使利用回旋流F所產生的隔離部38的驅動轉矩變大，從而易於使夾在間隙61中的灰塵脫離。 Further, in the electric vacuum cleaner 1 of the first embodiment, by providing the vane 83 in the partition portion 38, the driving torque of the partition portion 38 by the swirling flow F is increased, and the dust trapped in the gap 61 is easily formed. Get rid of.
此外，第1實施方式的電吸塵器1包括旋轉的隔離部38，因此除回旋流F以外還可利用隔離部38攪拌集塵室52內的灰塵，因此可實現集塵室52內的灰塵的分布密度的均質化，可消除灰塵的偏置而蓄積更多的灰塵。 Further, since the electric vacuum cleaner 1 of the first embodiment includes the rotating partition portion 38, the dust in the dust collecting chamber 52 can be stirred by the partition portion 38 in addition to the swirling flow F, so that the distribution of dust in the dust collecting chamber 52 can be realized. The homogenization of density eliminates the offset of dust and accumulates more dust.
因此，根據第1實施方式的電吸塵器1，可提供灰塵不易滯留在圓筒形狀的容器主體35與隔離部38之間的電吸塵器1。 Therefore, according to the electric vacuum cleaner 1 of the first embodiment, it is possible to provide the electric vacuum cleaner 1 in which dust does not easily remain between the cylindrical container main body 35 and the partition portion 38.
圖7是示意性地表示本發明的第2實施方式的電吸塵器的灰塵分離集塵裝置的縱截面圖。 FIG. 7 is a longitudinal cross-sectional view schematically showing a dust separating and dust collecting device of an electric vacuum cleaner according to a second embodiment of the present invention.
如圖7所示般，第2實施方式的灰塵分離集塵裝置7整體上呈大致圓柱形狀。灰塵分離集塵裝置7包括容器主體35、吸入管36、第一過濾濾器部37、隔離部38、返回過濾濾器部39、旋轉支撑部141、蓋壁42、噴出管43、及第二過濾濾器部45。 As shown in Fig. 7, the dust separating and dust collecting device 7 of the second embodiment has a substantially columnar shape as a whole. The dust separating and dust collecting device 7 includes a container body 35, a suction pipe 36, a first filter portion 37, a partition portion 38, a return filter portion 39, a rotation support portion 141, a cover wall 42, a discharge pipe 43, and a second filter.

另外，就灰塵分離集塵裝置7而言，作為安裝在吸塵器主體2的狀態下的姿勢，也可使圓筒形狀的容器主體35的中心線C朝向垂直方向，也可使該中心線C朝向水平方向，或者也可使該中心線C傾斜為其他任意角度來配置。 Further, in the dust separation and dust collecting device 7, the center line C of the cylindrical container main body 35 may be oriented in the vertical direction as the posture in the state of being attached to the cleaner body 2, and the center line C may be oriented. The horizontal direction, or the center line C can also be tilted to any other angle.
容器主體35呈在圖示上方的端部具有敞開端47、及在下方的端部具有封閉端48的有底圓筒形狀。在容器主體35內部形成有：分離室51，將含塵空氣離心分離為灰塵與空氣；及集塵室52，蓄積所分離的灰塵。 The container body 35 has a bottomed cylindrical shape having an open end 47 at an upper end portion and a closed end 48 at an lower end portion. Inside the container body 35, a separation chamber 51 is formed to centrifugally separate dust-containing air into dust and air, and a dust collecting chamber 52 to accumulate the separated dust.
吸入管36偏靠容器主體35的側壁35a的敞開端47側而連通連接於容器主體35，成為將含塵空氣取入至灰塵分離集塵裝置7內的入口。 The suction pipe 36 is connected to the container body 35 via the open end 47 side of the side wall 35a of the container body 35, and is an inlet for taking dust-containing air into the dust separating dust collecting device 7.
吸入管36將從管部3向灰塵分離集塵裝置7流入的空氣向容器主體35的內周面的切線方向朝容器主體35內引導，且在容器主體35內產生回旋流F。吸入管36一體地成形於側壁35a。 The suction pipe 36 guides the air flowing into the dust separating dust collector 7 from the pipe portion 3 toward the inner circumferential surface of the container body 35 in the container body 35, and generates a swirling flow F in the container body 35. The suction pipe 36 is integrally formed on the side wall 35a.
另外，吸入管36只要在容器主體35內產生回旋流F，則也可相對於與容器主體35的中心線C正交的平面，例如相對於中心線C朝向鉛直方向的情况下的水平面而傾斜。 Further, the suction pipe 36 may be inclined with respect to a horizontal plane in a vertical direction with respect to the center line C on a plane orthogonal to the center line C of the container body 35 as long as the swirling flow F is generated in the container body 35. .
第一過濾濾器部37呈較容器主體35短的圓筒形狀，第一過濾濾器部37的上方端部(靠近容器主體35的敞開端47的側的端部)，與設置在容器主體35的敞開端47的蓋壁42鄰接。 The first filter unit 37 has a cylindrical shape shorter than the container body 35, and an upper end portion of the first filter unit 37 (an end portion on the side close to the open end 47 of the container body 35) and a container body 35 are provided. The cover wall 42 of the open end 47 is adjacent.
第一過濾濾器部37收納在容器主體35內而在圓筒狀部外周面與容器主體35的圓筒狀部內周面之間形成環狀的分離室51，第一過濾濾器部37成為灰塵分離集塵裝置7的一次過濾器。 The first filter unit 37 is housed in the container body 35, and an annular separation chamber 51 is formed between the outer peripheral surface of the cylindrical portion and the inner peripheral surface of the cylindrical portion of the container body 35, and the first filter unit 37 becomes dust separation. A primary filter of the dust collecting device 7.
分離室51隔開第一過濾濾器部37的外周面與容器主體35的內周面而產生回旋流F來從含塵空氣分離灰塵與空氣。而且，在電動送風機8剛起動後或停止過渡等分離室51內的回旋流F未充分發展的期間，此外在回旋流F發展後當然也防止灰塵從容器主體35向噴出管43流出。 The separation chamber 51 is separated from the outer peripheral surface of the first filter unit 37 and the inner peripheral surface of the container body 35 to generate a swirling flow F to separate dust and air from the dust-containing air. Further, during the period in which the swirling flow F in the separation chamber 51 immediately after the start of the electric blower 8 or the stop transition is not sufficiently developed, it is of course prevented that the dust flows out from the container main body 35 to the discharge pipe 43 after the development of the swirling flow F.
此外，第一過濾濾器部37如圖7、及圖8所示般，包括在側面形成大的開口的圓筒形狀的保形框53、及設置在保形框53的第一過濾濾器55，第一過濾濾器55以包圍保形框53的方式卷附為圓筒形狀。 Further, as shown in FIGS. 7 and 8 , the first filter unit 37 includes a cylindrical shape-shaped frame 53 having a large opening formed on the side surface thereof, and a first filter element 55 provided in the shape-retaining frame 53 . The first filter 55 is wound into a cylindrical shape so as to surround the shape-retaining frame 53.
保形框53將第一過濾濾器55保持為圓筒形狀。保形框53包括： 直線狀的框部件56，多條相互隔開而配置在相當於圓筒形狀的側面的部分；及環狀的框部件57，與框部件56連結而相當於圓筒形狀的兩端部各自的緣。 The shape retaining frame 53 holds the first filter filter 55 in a cylindrical shape. The shape frame 53 includes: The linear frame member 56 is disposed at a portion that is spaced apart from each other and disposed on a side surface corresponding to the cylindrical shape, and the annular frame member 57 is coupled to the frame member 56 and corresponds to each of both end portions of the cylindrical shape. edge.
隔離部38呈直徑較第一過濾濾器部37大、且外徑較容器主體35小的形狀。隔離部38鄰接於第一過濾濾器部37的下方的端部(靠近容器主體35的封閉端48的側的端部)。隔離部38具有開口58，并且以通過間隙59連通連接的狀態將相互相鄰的分離室51與集塵室52隔開。 The partition portion 38 has a larger diameter than the first filter element portion 37 and has a smaller outer diameter than the container body 35. The partition portion 38 is adjacent to the lower end portion of the first filter filter portion 37 (the end portion on the side close to the closed end 48 of the container body 35). The partition portion 38 has an opening 58 and separates the separation chambers 51 adjacent to each other from the dust collecting chamber 52 in a state of being connected by the gap 59.
隔離部38的開口58較隔離部38的外周緣與容器主體35的內周面之間的環狀的間隙59靠近容器主體35的中心線C，與間隙59同樣地連通連接分離室51與集塵室52。 The opening 58 of the partition portion 38 is closer to the center line C of the container body 35 than the annular gap 59 between the outer peripheral edge of the partition portion 38 and the inner peripheral surface of the container body 35, and is connected to the separation chamber 51 and the set in the same manner as the gap 59. Dust chamber 52.
較隔離部38靠容器主體35的下方(底面)側的空間，為蓄積從分離室51通過間隙59流入的灰塵的集塵室52。間隙59將在分離室51內產生的回旋流F與灰塵一起引導至集塵室52，開口58使引導至集塵室52內的回旋流F向分離室51返回。 The space on the lower side (bottom surface) side of the container main body 35 is smaller than the partition portion 38, and is a dust collecting chamber 52 that accumulates dust that has flowed through the gap 59 from the separation chamber 51. The gap 59 guides the swirling flow F generated in the separation chamber 51 together with the dust to the dust collecting chamber 52, and the opening 58 returns the swirling flow F guided into the dust collecting chamber 52 to the separation chamber 51.
另外，隔離部38也可如圖7中的雙點劃線所示呈向容器主體35的底面敞開的有底圓筒形狀。該情况下，雙點劃線所示的隔離部38的圓筒形狀的側壁63外周面，在與容器主體35之間隔開有間隙61，此外在隔壁部38的下端與容器主體35的底面之間隔開有間隙62。 Further, the partition portion 38 may have a bottomed cylindrical shape that is open to the bottom surface of the container body 35 as indicated by a chain double-dashed line in FIG. In this case, the outer peripheral surface of the cylindrical side wall 63 of the partition portion 38 indicated by the alternate long and short dash line is separated from the container body 35 by a gap 61, and the lower end of the partition portion 38 and the bottom surface of the container body 35. There is a gap 62 between the intervals.
分離室51及集塵室52通過間隙59、間隙61、間隙62連通。間隙61遍及全周而隔開容器主體35的內周面與隔離部38的外周面。間隙59、間隙61、間隙62，將在分離室51內產生的回旋流F與灰塵一起引導至集塵室52。 The separation chamber 51 and the dust collection chamber 52 communicate with each other through the gap 59, the gap 61, and the gap 62. The gap 61 is separated from the inner circumferential surface of the container body 35 and the outer circumferential surface of the partition portion 38 over the entire circumference. The gap 59, the gap 61, and the gap 62 guide the swirling flow F generated in the separation chamber 51 together with the dust to the dust collecting chamber 52.
設置在隔離部38的開口58的返回過濾濾器部39，由不會使流入至集塵室52的線屑或棉屑等纖維狀的灰塵返回至分離室51的程度的孔眼粗的過濾器、例如網式過濾器形成。 The return filter unit 39 provided in the opening 58 of the partition portion 38 is a filter having a large aperture which does not allow the fibrous dust such as lint or cotton dust which flows into the dust collecting chamber 52 to return to the separation chamber 51. For example, a mesh filter is formed.
旋轉支撑部141以容器主體35的中心線C為旋轉軸而旋轉自如地支撑第一過濾濾器部37及隔離部38。旋轉支撑部141包括：第二軸承165，設置於容器主體35的底面；軸承保持部件166，設置於蓋壁42或噴出管43；第一軸承167，設置於軸承保持部件166；及軸芯部168，架設於第一軸承167與第二軸承165之間。 The rotation support portion 141 rotatably supports the first filter portion 37 and the partition portion 38 with the center line C of the container body 35 as a rotation axis. The rotation support portion 141 includes a second bearing 165 disposed on a bottom surface of the container body 35, a bearing holding member 166 disposed on the cover wall 42 or the discharge pipe 43, a first bearing 167 disposed on the bearing holding member 166, and a shaft core portion 168 is disposed between the first bearing 167 and the second bearing 165.
第一軸承167及第二軸承165為含浸有潤滑油的滑動軸承，且為發揮自潤滑性的所謂的無油軸承或滾珠軸承。 The first bearing 167 and the second bearing 165 are sliding bearings impregnated with lubricating oil, and are so-called oil-free bearings or ball bearings that exhibit self-lubricity.
軸承保持部件166包括從保持第一軸承167的中心部分呈放射狀延伸的多個骨材。 The bearing holding member 166 includes a plurality of aggregates that extend radially from a central portion that holds the first bearing 167.
軸芯部168包括：第一軸芯半部171，與第一過濾濾器部37一體成形；及第二軸芯半部172，固定在隔離部38。第一軸芯半部171及第二軸芯半部172呈與中心線C同心的圓柱形狀。 The shaft core portion 168 includes a first core core half 171 integrally formed with the first filter filter portion 37, and a second core core half portion 172 fixed to the partition portion 38. The first core half 171 and the second core half 172 have a cylindrical shape concentric with the center line C.
在第一軸芯半部171的上端部，設置有保持第一軸承67的第一軸承保持部173。在第二軸芯半部172的下端部，設置有保持第二軸承65的第二軸承保持部175。 At the upper end portion of the first core half 171, a first bearing holding portion 173 that holds the first bearing 67 is provided. At a lower end portion of the second core half 172, a second bearing holding portion 175 that holds the second bearing 65 is provided.
第一過濾濾器部37及隔離部38，通過旋轉支撑部141而旋轉自如地支撑，因此接受在分離室51內回旋的空氣的氣流即回旋流F而旋轉。 Since the first filter unit 37 and the partition portion 38 are rotatably supported by the rotation support portion 141, the swirl flow F, which is a flow of air swirling in the separation chamber 51, is rotated.
回旋流F在沿第一過濾濾器部37的外周面、及隔離部38的表面流動的過程中，或在通過第一過濾濾器55向第一過濾濾器部37的內側 流入的過程中，對第一過濾濾器部37及隔離部38賦予旋轉力。 The swirling flow F flows in the process of flowing along the outer peripheral surface of the first filter filter portion 37 and the surface of the partition portion 38, or toward the inside of the first filter filter portion 37 through the first filter filter 55. During the inflow, a rotational force is applied to the first filter element portion 37 and the partition portion 38.
蓋壁42堵塞容器主體35的敞開端47。蓋壁42具有相對於容器主體35而大致同心的開口42a。開口42a連通連接第一過濾濾器部37的內側的空間與噴出管43內。 The cover wall 42 blocks the open end 47 of the container body 35. The cover wall 42 has an opening 42a that is substantially concentric with respect to the container body 35. The opening 42a communicates with the space inside the first filter unit 37 and the inside of the discharge pipe 43.
第一過濾濾器部37相對於蓋壁42相對性地旋轉，因此在蓋壁42與第一過濾濾器部37的鄰接部分，設置有阻礙空氣從分離室51側向第一過濾濾器部37的內側空間流入的密封(seal)部181。 Since the first filter unit 37 relatively rotates with respect to the cover wall 42, the adjacent portion of the cover wall 42 and the first filter unit 37 is provided with air from the side of the separation chamber 51 toward the inside of the first filter unit 37. A seal portion 181 into which the space flows.
若假設灰塵等進入第一過濾濾器部37與蓋壁42之間的微小的間隙中，則阻礙第一過濾濾器部37旋轉。由此，密封部181確保第一過濾濾器部37與蓋壁42之間的微小的間隙中的空氣的流通，或阻礙灰塵的侵入而確保第一過濾濾器部37的切實的旋轉。密封部181例如呈所謂的迷宮(labyrinth)構造。 When dust or the like is entered into a slight gap between the first filter unit 37 and the cover wall 42, the first filter unit 37 is prevented from rotating. Thereby, the sealing portion 181 secures the flow of air in the minute gap between the first filter element portion 37 and the cover wall 42 or hinders the intrusion of dust, thereby ensuring reliable rotation of the first filter element portion 37. The sealing portion 181 has, for example, a so-called labyrinth structure.
噴出管43堵塞容器主體35的敞開端47而覆蓋蓋壁42。噴出管43為灰塵分離集塵裝置7中的空氣的出口，成為將通過第一過濾濾器部37及第二過濾濾器部45的空氣送出至電動送風機8的排氣風路182。 The discharge pipe 43 closes the open end 47 of the container body 35 to cover the cover wall 42. The discharge pipe 43 is an outlet of the air in the dust separation dust collector 7, and is an exhaust air passage 182 that sends the air passing through the first filter unit 37 and the second filter unit 45 to the electric blower 8.
第二過濾濾器部45對從蓋壁42的開口42a向排氣風路182流入的空氣過濾。第二過濾濾器部45在電動送風機8剛起動後或剛停止後等分離室51的回旋流F未充分發展的期間，捕集透過第一過濾濾器部37的微細的粒子狀的細塵，而防止微細的粒子狀的細塵到達電動送風機8。 The second filter unit 45 filters the air flowing in from the opening 42a of the cover wall 42 to the exhaust air passage 182. The second filter unit 45 collects fine particulate fine dust that has passed through the first filter unit 37 while the swirling flow F of the separation chamber 51 has not sufficiently developed immediately after the start of the electric blower 8 or immediately after the stop. Fine fine particulate fine dust is prevented from reaching the electric blower 8.
第二過濾濾器部45為呈圓盤形狀、且從中心側以放射狀延伸的凸折部分與凹折部分交替排列的折叠過濾器。 The second filter unit 45 is a pleated filter in which a convex shape and a concave portion which are formed in a disk shape and radially extend from the center side are alternately arranged.

如圖8所示般，第2實施方式的灰塵分離集塵裝置7，包括設置在第一過濾濾器部37而接受在分離室51內回旋的空氣的氣流的翼板183。 As shown in FIG. 8, the dust separating and dust collecting device 7 of the second embodiment includes a flap 183 which is provided in the first filter unit 37 and receives the air flow of the air swirled in the separation chamber 51.
翼板183設置在第一過濾濾器部37的內周側，向第一過濾濾器部37的中心線、即容器主體35的中心線C延伸。翼板183與保形框53一體化。翼板183接受通過第一過濾濾器55向第一過濾濾器部37的內側流入的空氣而對第一過濾濾器部37賦予旋轉力。 The flap 183 is provided on the inner peripheral side of the first filter unit 37, and extends toward the center line of the first filter unit 37, that is, the center line C of the container body 35. The flap 183 is integrated with the conformal frame 53. The flap 183 receives the air that has flowed into the inside of the first filter unit 37 through the first filter 55 and imparts a rotational force to the first filter unit 37.
其次，對本發明的第2實施方式的電吸塵器1的動作進行說明。 Next, the operation of the electric vacuum cleaner 1 according to the second embodiment of the present invention will be described.
此處，首先為與第2實施方式進行比較，而使用圖9(a)~9(c)、圖10對包括不相對於容器主體101旋轉的第一過濾濾器部102、及隔離部103的現有的電吸塵器104進行說明。 Here, first, in comparison with the second embodiment, the first filter unit 102 and the partition portion 103 that are not rotated with respect to the container body 101 are included in FIGS. 9(a) to 9(c) and FIG. The conventional electric vacuum cleaner 104 will be described.
圖9(a)、圖9(b)及圖9(c)是示意性地表示現有的電吸塵器的灰塵分離集塵裝置的橫截面圖。 9(a), 9(b), and 9(c) are cross-sectional views schematically showing a dust separating and dust collecting device of a conventional electric vacuum cleaner.
圖10是示意性地表示現有的電吸塵器的灰塵分離集塵裝置的縱截面圖。 Fig. 10 is a longitudinal cross-sectional view schematically showing a dust separating and dust collecting device of a conventional electric vacuum cleaner.
如圖9(a)所示般，在現有的電吸塵器104中，若超過第一過濾濾器部102的外周長的長條的纖維狀的灰塵fi通過回旋流F而流入至灰塵分離集塵裝置105，則存在灰塵fi的一端部以穿過的方式附著於過濾濾器106的情况。 As shown in Fig. 9 (a), in the conventional vacuum cleaner 104, a long fibrous dust fi exceeding the outer circumference of the first filter unit 102 flows into the dust separating dust collecting device through the swirling flow F. 105, there is a case where one end portion of the dust fi is attached to the filter 106 by passing therethrough.
而且，在現有的電吸塵器104中，第一過濾濾器部102固定於容器主體101而不旋轉，因此如圖9(b)所示般，使一端部附著於過濾濾器106的纖維狀的灰塵fi，在被回旋流F沖走的狀態下開始卷附於過濾濾器106。 Further, in the conventional vacuum cleaner 104, since the first filter unit 102 is fixed to the container body 101 without being rotated, as shown in FIG. 9(b), the fibrous dust of one end portion is attached to the filter 106. The film is attached to the filter 106 in a state of being washed away by the swirling flow F.
最終如圖9(c)及圖10所示般，纖維狀的灰塵fi卷附於過濾濾器106而無法容易地解開。 Finally, as shown in FIG. 9(c) and FIG. 10, the fibrous dust fi is attached to the filter 106 and cannot be easily unwound.
另一方面，圖11(a)、圖11(b)、圖11(c)及圖11(d)是示意性地表示第2實施方式的電吸塵器的灰塵分離集塵裝置的橫截面圖。 On the other hand, Fig. 11 (a), Fig. 11 (b), Fig. 11 (c), and Fig. 11 (d) are cross-sectional views schematically showing a dust separating and dust collecting device of the electric vacuum cleaner of the second embodiment.
此外，圖12是示意性地表示第2實施方式的電吸塵器的灰塵分離集塵裝置的縱截面圖。 In addition, FIG. 12 is a longitudinal cross-sectional view schematically showing a dust separating and dust collecting device of the electric vacuum cleaner of the second embodiment.
如圖11(a)所示般，即便為本實施方式的電吸塵器1，若超過第一過濾濾器部37的外周長的長條的纖維狀的灰塵fi通過回旋流F而流入至灰塵分離集塵裝置7，則也存在灰塵fi的一端部以穿過的方式附著於第一過濾濾器55的情况。 As shown in Fig. 11 (a), even in the vacuum cleaner 1 of the present embodiment, the long fibrous dust fi exceeding the outer circumference of the first filter unit 37 flows into the dust separation set by the swirling flow F. In the dust device 7, there is also a case where one end portion of the dust fi is attached to the first filter filter 55 so as to pass therethrough.
而且，如圖11(b)所示般，使一端部附著於第一過濾濾器55的纖維狀的灰塵fi，在被回旋流F沖走的狀態下開始卷附於第一過濾濾器55。 Further, as shown in FIG. 11(b), the fibrous dust fi having the one end portion attached to the first filter 55 is wound around the first filter 55 in a state of being washed away by the swirling flow F.
然而，在本實施方式的電吸塵器1中，第一過濾濾器部37隨著回旋流F旋轉(圖11(a)~11(d)中，實線箭頭R)，因此第一過濾濾器55與所附著的纖維狀的灰塵fi一起旋轉，由此被回旋流F沖走的灰塵fi與第一過濾濾器55的相對速度差較現有的電吸塵器104小，灰塵fi在卷附於第一過濾濾器55之前，在分離室51內被沖走更長時間、更長距離。 However, in the vacuum cleaner 1 of the present embodiment, the first filter unit 37 rotates with the swirling flow F (solid arrows R in FIGS. 11(a) to 11(d)), so the first filter 55 and The attached fibrous dust fi rotates together, whereby the relative speed difference between the dust fi washed away by the swirling flow F and the first filter filter 55 is smaller than that of the existing electric vacuum cleaner 104, and the dust fi is attached to the first filter. Before 55, it was washed away in the separation chamber 51 for a longer time and a longer distance.
在灰塵fi及第一過濾濾器部37正在持續旋轉時，以回旋流F的輕微的擾亂等為契機而如圖11(c)所示般，灰塵fi的一端部從第一過濾濾器55脫離或脫落。 When the dust fi and the first filter unit 37 are continuously rotating, a slight disturbance of the swirling flow F or the like is caused, and as shown in FIG. 11( c ), one end portion of the dust fi is detached from the first filter 55 or Fall off.
本實施方式的電吸塵器1與現有的電吸塵器104相比，灰塵fi與第一過濾濾器55的相對速度差小，灰塵fi在卷附於第一過濾濾器55之前有更長時間、更長距離的餘度。 The electric vacuum cleaner 1 of the present embodiment has a smaller relative speed difference between the dust fi and the first filter filter 55 than the conventional electric vacuum cleaner 104, and the dust fi has a longer time and a longer distance before being attached to the first filter filter 55. The margin.
因此，在本實施方式的電吸塵器1中，可能多次遇到回旋流F的輕微的擾亂等的契機，因此灰塵fi從第一過濾濾器55脫離或脫落的機會提高至相當程度。 Therefore, in the electric vacuum cleaner 1 of the present embodiment, a slight disturbance such as the swirling flow F may be encountered many times, and therefore the chance of the dust fi being detached or detached from the first filter 55 is increased to a considerable extent.
而且，最終如圖11(d)所示般，纖維狀的灰塵fi從第一過濾濾器55脫離、脫落，并如圖12所示般蓄積在集塵室52中。 Then, as shown in FIG. 11(d), the fibrous dust fi is detached from the first filter 55 and falls off, and is accumulated in the dust collecting chamber 52 as shown in FIG.
此外，回旋流F每次在回旋1圈時與從吸入管36流入至分離室51的新的含塵空氣合流，并且將風向改變為向容器主體35的中心線C方向，換言之向接近第一過濾濾器55的方向。已改變風向的回旋流F的一部分通過第一過濾濾器55且被引導至灰塵分離集塵裝置7外。 Further, the swirling flow F merges with the new dust-containing air flowing from the suction pipe 36 to the separation chamber 51 every time it is rotated one turn, and changes the wind direction to the center line C direction of the container main body 35, in other words, approaches the first The direction of the filter 55 is filtered. A part of the swirling flow F of the changed wind direction passes through the first filter 55 and is guided to the outside of the dust separating dust collecting device 7.
在該過程中，在圖9(a)~9(c)的現有的電吸塵器104的情况下，由於包括不旋轉的過濾濾器106，因此已改變風向的回旋流F的一部分持續通過過濾濾器106的大致固定位置。 In this process, in the case of the conventional electric vacuum cleaner 104 of Figs. 9(a) to 9(c), since the filter filter 106 that does not rotate is included, a part of the swirling flow F that has changed the wind direction continues to pass through the filter 106. The approximate fixed position.
如此一來，在過濾濾器106的該部位慢慢地附著灰塵，最終堵塞。若在過濾濾器106的特定部位產生堵塞，則堵塞部位的流速降低，進而範圍擴大，結果誘發過濾濾器106整體堵塞。 As a result, dust is slowly attached to the portion of the filter 106 and eventually clogged. When a clogging occurs in a specific portion of the filtration filter 106, the flow velocity of the clogging portion is lowered, and the range is further expanded, and as a result, the entire filter filter 106 is induced to be clogged.
相對於此，在本實施方式的電吸塵器1中，使第一過濾濾器55 隨著回旋流F旋轉，因此已改變風向的回旋流F的一部分不會持續通過第一過濾濾器55的固定位置，通過部位遍及全周而廣泛地分散。 On the other hand, in the electric vacuum cleaner 1 of this embodiment, the 1st filter filter 55 is made. As the swirling flow F rotates, a part of the swirling flow F that has changed the wind direction does not continue to pass through the fixed position of the first filter 55, and is widely dispersed throughout the entire passage.
因此，本實施方式的電吸塵器1在第一過濾濾器55的某狹窄的範圍不產生堵塞，易於維持透氣性，進而易於維持第一過濾濾器55整體的透氣性。 Therefore, the vacuum cleaner 1 of the present embodiment does not cause clogging in a narrow range of the first filter 55, and it is easy to maintain the gas permeability, and it is easy to maintain the gas permeability of the entire first filter 55.
而且，在本實施方式的電吸塵器1中，使隔離部38與第一過濾濾器部37一起旋轉，因此除回旋流F以外還可利用隔離部38攪拌集塵室52內的灰塵，因此可實現集塵室52內的灰塵的分布密度的均質化，可消除灰塵的偏置而蓄積更多的灰塵。 Further, in the vacuum cleaner 1 of the present embodiment, since the partition portion 38 is rotated together with the first filter element portion 37, the dust in the dust collecting chamber 52 can be stirred by the partition portion 38 in addition to the swirling flow F, so that it can be realized. The distribution density of the dust in the dust collecting chamber 52 is homogenized, and the dust is offset to accumulate more dust.
如此，本實施方式的電吸塵器1在容器主體35內包括旋轉自如的第一過濾濾器部37及隔離部38，因此可防止在分離室51內回旋的灰塵，尤其是纖維狀的灰塵卷附於第一過濾濾器部37。 As described above, the vacuum cleaner 1 of the present embodiment includes the first filter portion 37 and the partition portion 38 that are rotatable in the container body 35, so that dust that is swirled in the separation chamber 51 can be prevented, and in particular, fibrous dust is attached to the dust. The first filter unit 37.
此外，本實施方式的電吸塵器1，利用在容器主體35內產生的回旋流F而使第一過濾濾器部37及隔離部38旋轉，因此無需追加性的原動機等部件、或用以與回旋流F的流速同步的測定器或控制系統，可抑制零件件數的增加數量而確保可靠性。 Further, in the electric vacuum cleaner 1 of the present embodiment, the first filter unit 37 and the partition unit 38 are rotated by the swirling flow F generated in the container body 35, so that no additional components such as a prime mover or a swirling flow are required. The flow rate synchronization measuring device or control system of F can suppress the increase in the number of parts and ensure reliability.
進而，本實施方式的電吸塵器1在第一過濾濾器部37包括翼板183，由此可使第一過濾濾器部37及隔離部38的驅動轉矩變大，從而易於使回旋流F與第一過濾濾器部37及隔離部38的旋轉同步。 Further, the electric vacuum cleaner 1 of the present embodiment includes the flap 183 in the first filter unit 37, whereby the driving torque of the first filter unit 37 and the partition unit 38 can be increased, and the swirling flow F and the The rotation of one filter unit 37 and the partition 38 is synchronized.
進而此外，在本實施方式的電吸塵器1中，若設為兼具翼板183的保形框53，則在第一過濾濾器部37的組裝上無需追加作業。 Further, in the vacuum cleaner 1 of the present embodiment, when the shape-retaining frame 53 having the flap 183 is provided, no additional work is required for assembly of the first filter unit 37.
此外，本實施方式的電吸塵器1在第一過濾濾器部37的內周側 包括翼板183，由此不會在第一過濾濾器55的外周面、即暴露在回旋流F中的面產生流速複雜的分布或渦流，從而可避免灰塵附著於第一過濾濾器55。 Further, the electric vacuum cleaner 1 of the present embodiment is on the inner peripheral side of the first filter unit 37. The flap 183 is included, whereby a distribution or eddy current having a complicated flow velocity is not generated on the outer peripheral surface of the first filter 55, that is, the surface exposed in the swirling flow F, so that dust can be prevented from adhering to the first filter 55.
因此，根據本實施方式的電吸塵器1，可提供不易在位於圓筒形狀的容器主體35內部的圓筒形狀的第一過濾濾器55卷附纖維狀的灰塵的電吸塵器1。 Therefore, according to the electric vacuum cleaner 1 of the present embodiment, it is possible to provide the electric vacuum cleaner 1 in which the fibrous first dust is hardly wound around the cylindrical first filter filter 55 located inside the cylindrical container main body 35.
另外，本實施方式的電吸塵器1并不限定於箱型的電吸塵器，也可為立柱型(upright type)、條杆(stick)型、或者輕便(handy)型等電吸塵器。 Further, the electric vacuum cleaner 1 of the present embodiment is not limited to a box type electric vacuum cleaner, and may be an upright type, a stick type, or a handy type.
