Description

用於吸收粗顆粒和細粉塵的硬質地板吸嘴 Hard floor nozzle for absorbing coarse particles and fine dust

本發明涉及一種借助吸入氣流從地板吸收污垢和/或灰塵的吸塵器的吸嘴，其具有殼體、形成在殼體內部的吸入室、用於引導吸入氣流且通到吸入室中的吸入通道以及形成作為吸入室的底側開口的吸入口。 The present invention relates to a suction nozzle of a vacuum cleaner that absorbs dirt and/or dust from a floor by means of a suction airflow, having a housing, a suction chamber formed inside the housing, a suction passage for guiding the suction airflow and leading to the suction chamber, and A suction port is formed as a bottom side opening of the suction chamber.

實際中已知吸氣嘴，其稱為附件、也簡稱為吸嘴或者根據使用目的稱為硬地板吸嘴或者地毯吸嘴，而且這些吸嘴通常與吸塵器一起用於從地板吸收污垢和/或灰塵。具有這類吸嘴的吸塵器通常具有一個基體外殼，在該基體外殼中設置有用於形成吸入氣流的電動抽氣發動機。該吸嘴通常通過靈活的吸入軟管和/或操縱管而流體密封地與吸塵器相連。在吸塵機器人中，一般將吸嘴集成在基體外殼本身中。在吸嘴上設置有多個用於使污垢和/或灰塵從地板上脫離的刷排或類似物。這樣從地板上脫離的灰塵和/或污垢由吸入氣流攜帶並且至少在設置於基體外殼中的灰塵收集腔中在灰塵過濾袋中分離。 In practice, suction nozzles are known, referred to as attachments, also referred to as suction nozzles or as hard floor nozzles or carpet nozzles depending on the purpose of use, and these nozzles are often used with vacuum cleaners to absorb dirt and/or from the floor. dust. A vacuum cleaner having such a suction nozzle generally has a base casing in which an electric suction engine for forming a suction airflow is disposed. The nozzle is typically fluid-tightly connected to the vacuum cleaner via a flexible suction hose and/or steering tube. In a vacuum cleaner, the nozzle is generally integrated into the base housing itself. A plurality of brush rows or the like for detaching dirt and/or dust from the floor are provided on the suction nozzle. The dust and/or dirt thus detached from the floor is carried by the suction airflow and is separated in the dust filter bag at least in the dust collection chamber provided in the base casing.

從地板上待清除的污垢或灰塵根據各種顆粒大小區分為粗顆粒和細粉塵。在現有技術中，一方面已知針對粗顆粒的吸收而優化的吸嘴，而另一方面還設計了用於特別好 地吸收細粉塵的吸嘴。例如硬地板吸嘴通常不設置用於抽吸粗顆粒，而還存在其他的吸嘴，這些吸嘴能夠人工地借助於腳踏式開關在粗顆粒吸收和細粉塵吸收之間轉換。通過腳踏式開關的操作通常使刷排從吸嘴中伸出，通過該刷排使吸嘴相對於地板的間距增大，從而可以更好地吸收或吸入粗顆粒。但是，現有技術中已知的吸嘴僅能滿足相對立且相反的要求(即，要麼用於粗顆粒吸收要麼用於細粉塵吸收)，或者必須由使用者在不同的運行模式之間手動地切換。 The dirt or dust to be removed from the floor is classified into coarse particles and fine dust according to various particle sizes. In the prior art, on the one hand, a nozzle which is optimized for the absorption of coarse particles is known, and on the other hand, it is designed to be particularly good. A nozzle that absorbs fine dust. For example, hard floor nozzles are generally not provided for pumping coarse particles, but there are other nozzles that can be manually switched between coarse particle absorption and fine dust absorption by means of a foot switch. The operation of the foot switch generally causes the brush row to protrude from the nozzle, by which the distance of the nozzle relative to the floor is increased, so that coarse particles can be better absorbed or sucked. However, the nozzles known in the prior art can only meet the opposite and opposite requirements (ie either for coarse particle absorption or for fine dust absorption) or must be manually operated by the user between different operating modes. Switch.

發明概要 Summary of invention

由此出發，本發明的目的在於說明一種用於吸收污垢和/或灰塵的吸嘴，該吸嘴對於不同的顆粒大小是通用的並且特別是具有能夠特別好地吸收粗顆粒的特徵。該吸嘴既能夠吸收粗顆粒也能夠吸收細粉塵，而為此不必手動地切換吸嘴的運行模式。此外符合預期的是，這類吸嘴的特徵在於：小的推進力和/或較低的噪聲污染。 Starting from this, the object of the invention is to specify a nozzle for absorbing dirt and/or dust which is versatile for different particle sizes and in particular has the characteristic of being able to absorb coarse particles particularly well. The nozzle can absorb both coarse particles and fine dust, and for this purpose it is not necessary to manually switch the operating mode of the nozzle. Furthermore, it is expected that such nozzles are characterized by small propulsion and/or low noise pollution.

本發明的目的通過獨立請求項中所述的特徵得以實現。有利的設計在附屬請求項中說明。 The object of the invention is achieved by the features described in the independent claims. An advantageous design is described in the accompanying claims.

相應地，該目的通過一種借助吸入氣流從地板吸收污垢和/或灰塵的吸塵器的吸嘴得以實現，該吸嘴具有殼體、形成在殼體內部的吸入室、用於引導吸入氣流並且通到吸入室中的吸入通道和形成作為吸入室的底側開口的吸入口，其中，吸入口具有一個中央吸入口區段以及兩個位於 中央吸入口區段兩側的側面吸入口區段，而且中央吸入口區段這樣設計，即，中央吸入口區段的寬度由吸入通道朝向吸嘴的正面增大而且中央吸入口區段的高度由吸入通道朝向吸嘴的正面以6°且10°的角度下降。 Accordingly, the object is achieved by a suction nozzle of a vacuum cleaner that absorbs dirt and/or dust from the floor by means of a suction air flow, the suction nozzle having a housing, a suction chamber formed inside the housing, for guiding the suction airflow and leading to a suction passage in the suction chamber and a suction port forming a bottom side opening as a suction chamber, wherein the suction port has a central suction port section and two side suction port sections on both sides of the central suction port section, and the center The suction port section is designed such that the width of the central suction port section is increased by the suction passage toward the front side of the suction nozzle and the height of the central suction inlet section is directed by the suction passage toward the front of the suction nozzle. 6° and The angle of 10° drops.

隨後，參照附圖借助優選的實施方式進一步說明本發明。其中：圖1以吸嘴的底視圖示出了根據本發明的一個優選實施方式的吸嘴，而且圖2以立體視圖示出了根據圖1的吸嘴。 The invention will be further elucidated with the aid of preferred embodiments with reference to the drawings. 1 is a bottom view of the nozzle showing a nozzle according to a preferred embodiment of the invention, and FIG. 2 shows the nozzle according to FIG. 1 in a perspective view.

根據本發明的一種優選實施方式，圖1和圖2示出了吸嘴、也稱為地板吸嘴的示意性底視圖。該吸嘴具有塑膠構成的殼體1，在該殼體上在底側形成底部平板2。在底部平板2下方形成吸入室3，吸入通道4通入該吸入室中而且該吸入室作為底側的開口而形成吸入口5。如從圖1中能夠看出，底部平板2以及吸入口5具有等腰三角形的形狀，該等腰三角形的底邊6a沿推進方向表示吸嘴的正面。 In accordance with a preferred embodiment of the present invention, Figures 1 and 2 show schematic bottom views of a nozzle, also referred to as a floor nozzle. The nozzle has a plastic housing 1 on which a bottom plate 2 is formed on the bottom side. A suction chamber 3 is formed below the bottom plate 2, into which the suction passage 4 opens and which serves as a suction opening 5 on the bottom side. As can be seen from Fig. 1, the bottom plate 2 and the suction port 5 have the shape of an isosceles triangle, and the bottom edge 6a of the isosceles triangle indicates the front surface of the nozzle in the advancing direction.

吸入通道4與設置在殼體1的上側上的連接套筒(未示出)流體密封地連接。在該連接套筒上，操縱管和/或靈活的軟管可以與吸塵器的基體外殼流體密封地連接，在該基體外殼中設置有用於形成吸入氣流的電驅動抽氣發動機。在設置在基體外殼中的灰塵收集腔中，從待清潔的地板上由吸入氣流攜帶的污垢和/或灰塵能夠在灰塵過濾袋中分離。 The suction passage 4 is fluid-tightly connected to a connecting sleeve (not shown) provided on the upper side of the housing 1. On the connecting sleeve, the actuating tube and/or the flexible hose can be fluid-tightly connected to the base housing of the vacuum cleaner, in which an electrically driven pumping engine for forming a suction air flow is arranged. In the dust collecting chamber provided in the base casing, dirt and/or dust carried by the suction airflow from the floor to be cleaned can be separated in the dust filter bag.

吸入口5具有一個中央吸入口區段6以及位於該中央吸入口區段6兩側或從側面包圍該中央吸入口區段6的兩個側面吸入口區段7。側面吸入口區段7由吸入通道4線性地分別朝向等腰三角形的角7a延伸，從而兩個側面吸入口區段7的縱向延伸方向之間的夾角α為135°。通過內側和外側的側面流體密封件8流體技術地限定側面吸入口區段7。外側的側面流體密封件8由等腰三角形的各個角7a沿各個側邊延伸並且在部分限定了吸入通道4的兩個側邊之間以半圓形相互匯合。 The suction port 5 has a central suction port section 6 and two side suction port sections 7 located on either side of the central suction port section 6 or laterally surrounding the central suction port section 6. The side suction section 7 extends linearly from the suction channel 4 towards the angle 7a of the isosceles triangle, respectively, such that the angle α between the longitudinal extensions of the two side suction sections 7 is 135°. The side suction section 7 is fluidically defined by the inner and outer side fluid seals 8. The outer side fluid seals 8 extend along the respective sides by respective corners 7a of the isosceles triangle and merge with each other in a semicircular shape between the two sides defining the suction passage 4.

相應地，吸嘴的整個背面通過外側的側面流體密封件8限定，這些側面流體密封件8主要配備作為刷排。內側的側面流體密封件8近似平行於外側的側面流體密封件8遠離吸入通道4這樣朝角7a的方向延伸，即，在兩個內側的側面流體密封件8之間的吸入通道4上形成了用於吸入氣流的空氣通路9。該空氣通路9現具有約32mm的寬度，而兩個側面吸入口區段7在吸入通道4的區域內分別具有約33mm的寬度。通過上述尺寸實現了，吸入氣流的約45%的部分由吸入通道4流動通過中央吸入口區段6，而約55%的剩餘部分均勻地分佈在兩個側面吸入口區段7上。 Correspondingly, the entire back side of the nozzle is defined by the outer side fluid seal 8, which is primarily provided as a brush row. The inner side fluid seal 8 is approximately parallel to the outer side of the side fluid seal 8 and extends away from the suction channel 4 in the direction of the angle 7a, ie on the suction channel 4 between the two inner side fluid seals 8 An air passage 9 for drawing in the airflow. The air passage 9 now has a width of approximately 32 mm, while the two side suction ports 7 each have a width of approximately 33 mm in the region of the suction channel 4. By the above dimensions it is achieved that about 45% of the suction airflow flows through the central suction section 6 by the suction passage 4, while about 55% of the remainder is evenly distributed over the two side suction sections 7.

類似於吸入口5以及底部平板2，中央吸入口區段6具有等腰三角形的形狀，其中，兩個內側的側面流體密封件8流體密封地限定中央吸入口區段6的側邊。如上所述，在中央吸入口區段6的尖部上設置通向吸入通道4的空氣通路9，而與之相對地在底邊6a並且與吸嘴的正面重合地設置有用於 至少局部密封中央吸入口區段6的前側的流體密封件11。 Similar to the suction port 5 and the bottom plate 2, the central suction port section 6 has the shape of an isosceles triangle, wherein the two inner side fluid seals 8 fluidly define the sides of the central suction port section 6. As described above, the air passage 9 leading to the suction passage 4 is provided at the tip end of the central suction port section 6, and oppositely to the bottom edge 6a and coincident with the front surface of the suction nozzle, The fluid seal 11 on the front side of the central suction port section 6 is at least partially sealed.

一方面，中央吸入口區段6的寬度以漏斗狀或V形的方式由吸入通道4直線式地向底邊6a或吸嘴的正面增大，其中，另一方面，中央吸入口區段6的高度由吸入通道4直線式地向底邊6a或吸嘴的正面以約8°的角度下降。由此中央吸入口區段6作為一類流體擴散器而起到作用，從而通過這樣設計的中央吸入口區段6能夠特別好地吸收粗顆粒。 On the one hand, the width of the central suction port section 6 is linearly increased from the suction channel 4 to the bottom edge 6a or the front side of the nozzle in a funnel or V-shape, wherein, on the other hand, the central suction section 6 The height is linearly lowered by the suction passage 4 toward the bottom edge 6a or the front surface of the nozzle at an angle of about 8°. The central suction port section 6 thus acts as a type of fluid diffuser, so that the central suction section 6 thus designed can absorb coarse particles particularly well.

前側的流體密封件11設計為柔軟的密封唇，從而粗顆粒可以經過該密封唇。處於中央吸入口區段6中的粗顆粒由吸入氣流攜帶並且穿過吸入通道4而吸入。前側的流體密封件11由底部平板2一直延伸到地板，但是其中，在前側的流體密封件11和吸嘴的角7a之間分別側面地形成近似50mm的縫隙。由此設計作為密封唇的前側的流體密封件11在經過粗顆粒時偏轉進入吸入室3中，而在此不會觸及內側的側面流體密封件8。 The front side fluid seal 11 is designed as a soft sealing lip so that coarse particles can pass through the sealing lip. The coarse particles in the central suction port section 6 are carried by the inspiratory flow and are drawn through the suction passage 4. The front side fluid seal 11 extends from the bottom plate 2 to the floor, but wherein a gap of approximately 50 mm is formed laterally between the fluid seal 11 on the front side and the corner 7a of the nozzle, respectively. The fluid seal 11 designed as the front side of the sealing lip is deflected into the suction chamber 3 when passing through the coarse particles, without the inner side fluid seal 8 being touched here.

通過前側的流體密封件11已經降低了由吸入氣流而引起的噪聲污染的出現，而為了進一步降低噪聲污染設置有用於聲音屏障的裝置12，該裝置在圖1和2的圖示中設計為與殼體1一件式成型的、V形的條帶，該條帶由底部平板2朝地板取向，但在此不會觸及地板。在中央吸入口區段6中，這樣設計的、用於聲音屏障的裝置12在中央吸入口區段6中沿吸入氣流方向設置在形成吸嘴正面的底邊6a與吸入通道4之間。在未示出的可選設計中，用於聲音屏障的裝置12也可以設置在中央吸入口區段6的正面或者在吸嘴的 正面上設置在前側的流體密封件11的部分之間。同樣地，前側的流體密封件11可以設計成通過在中央吸入口區段6的正面橫向於推進方向而前後設置的多個用於聲音屏障的裝置12。 The occurrence of noise pollution caused by the suction air flow has been reduced by the fluid seal 11 on the front side, and the device 12 for the sound barrier is provided for further reducing noise pollution, which device is designed in the illustrations of Figures 1 and 2 to The housing 1 is a one-piece, V-shaped strip that is oriented by the bottom panel 2 towards the floor, but does not touch the floor. In the central suction section 6, the device 12 designed for the sound barrier is arranged in the central suction section 6 between the bottom edge 6a forming the front side of the nozzle and the suction channel 4 in the direction of the suction air flow. In an alternative design not shown, the means 12 for the sound barrier can also be arranged on the front side of the central suction section 6 or in the mouthpiece The front side is disposed between portions of the fluid seal 11 on the front side. Likewise, the fluid seal 11 on the front side can be designed as a plurality of means 12 for the sound barrier arranged one behind the other in front of the front side of the central suction section 6 transverse to the direction of advancement.

前側的流體密封件11和用於聲音屏障的裝置12之間的間距約為15mm，而用於聲音屏障的裝置12和內側的側面流體密封件8之間的間距分別約為22mm。用於聲音屏障的裝置12也可以替代性地由兩個約5cm長的刷排組成，這兩個刷排在底部平板2上以約30°相互錯開地設置，以使得至少限制了由吸入通道4向吸嘴正面的直接的聲音發射。 The spacing between the fluid seal 11 on the front side and the device 12 for the sound barrier is about 15 mm, and the spacing between the device 12 for the sound barrier and the side fluid seal 8 on the inside is about 22 mm, respectively. The device 12 for the sound barrier can alternatively also consist of two brush rows of approximately 5 cm length, which are arranged on the bottom plate 2 at approximately 30° offset from one another such that at least the suction channel is limited 4 Direct sound emission to the front of the nozzle.

通過上述中央吸入口區段的設計方案(該中央吸入口區段具有由吸入通道向吸嘴正面逐漸增大的寬度並且具有以6°且10°的角度逐漸下降的高度)實現了細粉塵以及粗顆粒的特別有效的吸收，而無需像在現有技術所已知的設計方案中需要在細粉塵和粗顆粒之間手動切換。另外，通過試驗證實的側面吸入口區段7的尺寸另外還實現了較高的流體速度以及較大的體積流量，這另外還促使了非常好且有效的細粉塵吸收。由於吸入口5具有相對較小的真空附著面積，因此上述設計方案的特徵在於相對較小的推進力。另一方面，因為中央吸入口區段6與之相對地設計為敞開的，吸嘴另外還具有的特徵在於非常有效的粗顆粒吸收，其中，由於用於聲音屏障的裝置12以及前側的流體密封件11僅產生較低的噪聲污染。 By the design of the central suction port section described above (the central suction port section has a width that gradually increases from the suction passage toward the front of the suction nozzle and has 6° and A highly gradual decrease in the angle of 10° achieves a particularly efficient absorption of fine dust and coarse particles without the need to manually switch between fine dust and coarse particles as in the designs known from the prior art. In addition, the size of the side suction section 7 which has been experimentally confirmed additionally achieves a higher fluid velocity and a larger volumetric flow, which additionally contributes to very good and effective fine dust absorption. Since the suction port 5 has a relatively small vacuum attachment area, the above design is characterized by a relatively small propulsive force. On the other hand, since the central suction port section 6 is designed to be open opposite thereto, the nozzle additionally has the feature of very efficient coarse particle absorption, since the device 12 for the sound barrier and the front side are fluid-tight. Piece 11 produces only low noise pollution.
