此外，本發明係有關於一種具有吸嘴的抽吸式清潔設備，其中，其吸嘴具有提供通往風扇的流體連接的抽吸通道，其中，抽吸通道之抽吸通道端區係與抽吸口連通，其中，抽吸通道端區具有數個與抽吸口(6)連通的流動開口，該等流動開口係呈階梯狀連接，使得，自抽吸口出發穿過第一流動開口以流入抽吸通道端區的第一流動分量係在抽吸通道端區內從抽吸通道端區之第二流動開口旁邊流過，其中，第一流動分量與穿過第二流動開口以流入抽吸通道端區的第二流動分量相加。 In addition, the present invention relates to a suction-type cleaning device having a suction nozzle, wherein the suction nozzle has a suction channel which provides a fluid connection to a fan, wherein an end region of the suction channel of the suction channel is connected with the suction The suction port is connected, wherein the end region of the suction channel has a plurality of flow openings communicating with the suction port (6), and the flow openings are connected in a stepped manner, so that the suction port passes through the first flow opening to The first flow component flowing into the end region of the suction channel flows in the end region of the suction channel beside the second flow opening in the end region of the suction channel, wherein the first flow component and the second flow opening pass through the second flow opening to flow into the suction The second flow component of the end region of the suction channel is added.

上述類型之吸嘴及抽吸式清潔設備在先前技術中為已知。 Suction nozzles and suction-type cleaning devices of the above-mentioned type are known in the prior art.

此吸嘴例如可按照附加件之樣式而建構，並且可將其與抽吸式清潔設備之基本設備以可分離的方式連接在一起。作為替代方案，此吸嘴亦可與此抽吸式清潔設備一體式地建構。此吸嘴具有抽吸通道，其一側與抽吸式清潔設備之風扇存在流體連接，另一側則與抽吸口連通。在風扇工作時，透過抽吸口對待清潔表面施加負壓，從而將處於表面上之灰塵及/或污物穿過抽吸通道以朝待吸物收集容器之方向輸送。 This nozzle can be constructed, for example, in the form of an add-on, and can be detachably connected to the basic equipment of the suction-type cleaning device. Alternatively, the suction nozzle can also be constructed in one piece with this suction cleaning device. This nozzle has a suction channel, one side of which is in fluid connection with the fan of the suction cleaning device, and the other side is in communication with the suction port. When the fan is in operation, a negative pressure is applied to the surface to be cleaned through the suction port, so that the dust and / or dirt on the surface is passed through the suction channel to be conveyed in the direction of the to-be-collected container.

公開案US 2008/0209671 A1例如揭露過此種解決方案。 The publication US 2008/0209671 A1 discloses such a solution, for example.

基於上述先前技術，本發明之目的在於提供一種吸嘴，其係以與該吸嘴之結構條件無關的方式，沿抽吸口具有均勻的抽吸空氣強度，使得此吸嘴較佳地在其整個寬度範圍內達到最佳的清潔效果。 Based on the foregoing prior art, the object of the present invention is to provide a suction nozzle which has a uniform suction air intensity along the suction port in a manner independent of the structural conditions of the nozzle, so that the suction nozzle is preferably located at Best cleaning results across the entire width.

為達成上述目的，本發明提出：抽吸通道係偏心地連接抽吸口，並且單側地對應於抽吸口之端區，其中，抽吸通道端區使得抽吸通道不對稱地連接至抽吸口。 In order to achieve the above object, the present invention proposes that the suction channel is eccentrically connected to the suction port and corresponds unilaterally to the end region of the suction port, wherein the end region of the suction channel makes the suction channel asymmetrically connected to the suction port. Suction mouth.

抽吸口係透過數個流動開口以與抽吸通道端區相連接。諸流動開口就抽吸口之縱向而言較佳係依次地與抽吸口連通，使得，數個流動分量獨立地流入抽吸通道端區，並且在其中呈階梯狀地相加。因此，與先前技術不同，空氣並非僅穿過單獨一個流動開口以流入抽吸通道端區。確切而言，抽吸空氣係分成數個流動分量，該等流動分量以不同的流逕自抽吸口出發而進入抽吸通道端區。可將流動開口放置及設計在抽吸通道端區上，從而沿抽吸口提供均勻的抽吸空氣強度。因此，在抽吸通道端區內，穿過就抽吸通 道而言為最遠的流動開口以進入的流動分量，係從建構在最遠的流動開口與朝風扇之方向導引的抽吸通道之間的抽吸通道端區上之其他的流動開口旁邊流過。因此，抽吸通道端區係沿抽吸口按照收集通道之樣式而建構，該收集通道係用作為朝風扇導引的抽吸通道與抽吸口之間的調節器。可透過流動開口之數目、佈置方案及大小，包括抽吸通道端區內之入流截面，以單獨地在每個流動開口上影響抽吸空氣流之強度。如此建構的抽吸通道端區使得抽吸通道不對稱地連接至抽吸口，從而就吸嘴之幾何形狀及所提供的結構空間而言存在較大的靈活性。 The suction port is connected to the end region of the suction channel through a plurality of flow openings. The flow openings are preferably communicated with the suction port sequentially in terms of the longitudinal direction of the suction port, so that several flow components flow independently into the end region of the suction channel and are added stepwise therein. Therefore, unlike the prior art, air does not just pass through a single flow opening to flow into the end region of the suction channel. Specifically, the suction air is divided into several flow components, which flow from the suction port with different flow paths and enter the end region of the suction channel. The flow opening can be placed and designed on the end area of the suction channel to provide uniform suction air intensity along the suction opening. Therefore, in the end region of the suction channel, the flow component that enters through the flow opening that is the furthest in terms of the suction channel is derived from the flow channel constructed at the furthest opening and the suction channel guided in the direction of the fan The other suction openings in the end region of the suction channel flow next to it. Therefore, the end region of the suction channel is constructed along the suction port in the form of a collection channel, which serves as a regulator between the suction channel and the suction port, which is directed towards the fan. The number, arrangement, and size of the flow openings, including the inflow cross section in the end zone of the suction channel, can be used to individually influence the intensity of the suction air flow at each flow opening. The end region of the suction channel thus constructed makes the suction channel asymmetrically connected to the suction port, so that there is greater flexibility in terms of the geometry of the suction nozzle and the structural space provided.

佈置在抽吸口與抽吸通道之間的抽吸通道端區特別是可平行地沿抽吸口佈置。抽吸通道端區原則上可在抽吸通道中之任意位置上具有過渡區。本發明在此提出：較佳地將抽吸通道端區於端側上連接至抽吸通道，使得抽吸通道端區成為抽吸通道之端側的突起。若抽吸通道端區為獨立於抽吸通道而建構的元件，則該抽吸通道可具有用於例如與抽吸通道端區構成可分離的連接之接合區。抽吸通道端區在流體技術上係藉由數個流動開口以與抽吸口相連接，其中，諸抽吸口較佳係佈置成使得抽吸空氣強度即使在抽吸口之邊緣區域內亦為最佳。 The suction channel end region, which is arranged between the suction opening and the suction channel, can be arranged in parallel along the suction opening. The suction channel end region can in principle have a transition zone at any position in the suction channel. The present invention proposes that the end region of the suction channel is preferably connected to the suction channel on the end side, so that the end region of the suction channel becomes a protrusion on the end side of the suction channel. If the end region of the suction channel is an element that is constructed separately from the suction channel, the suction channel may have a joint region for forming a separable connection with the end region of the suction channel, for example. The end region of the suction channel is fluidly connected to the suction port by several flow openings, wherein the suction ports are preferably arranged so that the strength of the suction air is even in the edge area of the suction port. For the best.

此外，本發明提出：抽吸通道端區係呈長條形，其中，諸流動開口就抽吸口之縱向而言係依次地與抽吸口連通。流動開口之開口平面之表面法線較佳地可垂直於抽吸通道端區之縱向延伸度。由於抽吸式清潔設備之吸嘴通常具有長條形的抽吸口，該抽吸口之縱向延伸度係橫向於抽吸式清潔設備或吸嘴之主運動方向，而根據本發明，與抽吸口連通的抽吸通道端區同樣係呈長條形。將抽 吸通道端區與抽吸口連接在一起的流動開口係被定向成使得開口平面之表面法線總是垂直於抽吸通道端區之縱向延伸度。根據較佳建構方案，抽吸通道端區就吸嘴在清潔操作期間之常規定向而言係佈置在抽吸口上方，特別是與抽吸口平行地佈置。 In addition, the present invention proposes that the end region of the suction channel is elongated, in which the flow openings are sequentially communicated with the suction port in terms of the longitudinal direction of the suction port. The surface normal of the opening plane of the flow opening may preferably be perpendicular to the longitudinal extent of the end region of the suction channel. Since the suction nozzle of a suction cleaning device usually has a long suction port, the longitudinal extension of the suction port is transverse to the main movement direction of the suction cleaning device or the nozzle. According to the present invention, The end region of the suction channel communicating with the suction port is also elongated. The flow opening connecting the suction channel end region with the suction port is oriented so that the surface normal of the plane of the opening is always perpendicular to the longitudinal extent of the suction channel end region. According to a preferred embodiment, the end region of the suction channel is arranged above the suction port, in particular in parallel to the suction port, in terms of the normal orientation of the suction nozzle during the cleaning operation.

此外，本發明提出：諸流動開口具有包含不同大小及/或不同形狀的截面面積的開口平面。可透過流動開口之大小及形狀以在每個流動開口上單獨地調節抽吸空氣流之強度。在此過程中，流動開口之大小係依照在抽吸通道端區內具體所期望的壓力損失而有所不同。諸流動開口特別是必須設計成使得該等流動開口確保抽吸空氣強度在抽吸口內之均勻分佈。 In addition, the present invention proposes that the flow openings have opening planes including cross-sectional areas of different sizes and / or shapes. The size and shape of the flow openings can be used to individually adjust the intensity of the suction air flow at each flow opening. During this process, the size of the flow openings will vary according to the pressure loss specifically desired in the end region of the suction channel. The flow openings must be designed in particular so that they ensure a uniform distribution of the intensity of the suction air within the suction opening.

根據一種較佳技術方案，本發明提出：流動開口為噴嘴之部分。根據該實施方案，抽吸通道端區係透過數個噴嘴以與抽吸口相連接，使得，除去例如截面面積大小之其他因素外，同樣透過噴嘴之形狀及大小以確定流動之速度及/或方向。在實踐中，可改變噴嘴之形狀及大小，以在抽吸口範圍內實現均勻的抽吸空氣強度。 According to a preferred technical solution, the present invention proposes that the flow opening is part of the nozzle. According to this embodiment, the end region of the suction channel is connected to the suction port through a plurality of nozzles, so that, among other factors such as the size of the cross-sectional area, the shape and size of the nozzle are also used to determine the speed and / or direction. In practice, the shape and size of the nozzle can be changed to achieve uniform suction air intensity within the range of the suction port.

就此而言，諸噴嘴可在抽吸通道端區與抽吸口之間提供不同長度的流徑。因此，該等噴嘴可建構為互不相同的長度。如此，便能同樣個別化地調節在相應的噴嘴或流動開口上出現的壓力損失。 In this regard, the nozzles can provide different lengths of flow paths between the suction channel end region and the suction port. Therefore, the nozzles can be constructed with different lengths. In this way, the pressure losses occurring at the corresponding nozzles or flow openings can also be adjusted individually.

此外，根據本發明：抽吸通道端區係朝其縱向延伸度之方向反向於其流動方向而呈一端漸細。根據該實施方案，抽吸通道端區係沿其縱向延伸度具有逐漸變小的連續的流動截面，使得抽吸通道端區自風扇出發直至最遠的流動開口逐漸變小。因此，諸流 動開口之相應的入流路徑係呈階梯狀佈置。 In addition, according to the present invention, the end region of the suction channel is tapered at one end in the direction opposite to the direction of its longitudinal extension to the direction of its flow. According to this embodiment, the end region of the suction channel has a progressively smaller continuous flow cross section along its longitudinal extent, so that the end opening of the suction channel gradually decreases from the fan to the furthest opening. Therefore, the corresponding inflow paths of the flow openings are arranged stepwise.

根據一種特別的實施方案，本發明提出：抽吸通道具有兩個在流體技術上呈並聯的抽吸通道端區。特別是，兩個抽吸通道端區之縱向延伸度可相互平行。根據該實施方案，兩個抽吸通道端區中之每一者較佳地皆與自有的抽吸口連通。兩個抽吸通道端區可相互間隔地佈置在此吸嘴之殼體中。此吸嘴例如可具有第一抽吸口，該第一抽吸口就此吸嘴在清潔操作期間之常規前進運動而言係處於前方，且具有第二抽吸口，而該第二抽吸口就沿相反的後退方向之移動而言係處於前方。因此，此吸嘴可在該二個相反的方向上實現同樣的最佳清潔效果。 According to a particular embodiment, the invention proposes that the suction channel has two suction channel end regions which are fluidically parallel. In particular, the longitudinal extents of the end regions of the two suction channels can be parallel to each other. According to this embodiment, each of the two suction channel end regions is preferably in communication with its own suction port. The two suction channel end regions can be arranged at a distance from one another in the housing of the nozzle. This suction nozzle may have, for example, a first suction opening, which is located in front of the conventional forward movement of the suction nozzle during a cleaning operation, and has a second suction opening, and the second suction opening As far as the movement in the opposite backward direction is concerned. Therefore, the nozzle can achieve the same best cleaning effect in the two opposite directions.

此外，本發明提出：抽吸通道端區具有二至十個、特別是三至五個流動開口。抽吸通道端區上所建構的流動開口愈多，在抽吸口上對抽吸空氣強度所實施的調節便愈精細。其中，抽吸口愈長，便設置愈多的流動開口。 Furthermore, the invention proposes that the end region of the suction channel has two to ten, in particular three to five, flow openings. The more flow openings are formed in the end region of the suction channel, the finer the adjustment of the suction air intensity at the suction port will be. Among them, the longer the suction port, the more flow openings are provided.

最後，由流動開口所決定的壓力損失之大小為抽吸通道端區內之壓力損失的至少五倍，特別是至少十倍。為了在所有的流動開口上實現均勻的體積流量，需要定義流動開口之截面面積之大小，以及確定抽吸通道端區內之流動截面之大小。其中，抽吸通道端區內之流動截面為實質上垂直於主流動方向的截面。就流動截面之設計方案而言，抽吸通道端區內之壓力損失以至少五倍、但尤佳地至少十倍的程度，小於各流動開口所引起的壓力損失。換言之，諸流動開口必須引起至少五倍、尤佳地至少十倍之壓力損失，以確保抽吸口上之抽吸空氣強度之均勻分佈。 Finally, the magnitude of the pressure loss determined by the flow opening is at least five times, especially at least ten times, the pressure loss in the end region of the suction channel. In order to achieve uniform volume flow across all flow openings, it is necessary to define the size of the cross-sectional area of the flow openings and the size of the flow cross-section in the end region of the suction channel. The flow cross section in the end region of the suction channel is a cross section substantially perpendicular to the main flow direction. In terms of the design of the flow cross section, the pressure loss in the end region of the suction channel is at least five times, but particularly preferably at least ten times, less than the pressure loss caused by each flow opening. In other words, the flow openings must cause a pressure loss of at least five times, and preferably at least ten times, to ensure a uniform distribution of the intensity of the suction air at the suction port.

除前述吸嘴外，本發明還提出一種具有吸嘴、特別是具有前文 所描述之吸嘴的抽吸式清潔設備，其中，其吸嘴具有提供通往風扇的流體連接的抽吸通道，其中，抽吸通道之抽吸通道端區係與抽吸口連通，其特徵在於：抽吸通道端區具有數個與抽吸口連通的流動開口，該等流動開口係呈階梯狀連接，使得，自抽吸口出發穿過第一流動開口以流入抽吸通道端區的第一流動分量係在抽吸通道端區內從抽吸通道端區之第二流動開口旁邊流過，其中，第一流動分量與穿過第二流動開口以流入抽吸通道端區的第二流動分量相加，且其中，抽吸通道係偏心地連接抽吸口，並且單側地對應於抽吸口之端區，其中，抽吸通道端區使得抽吸通道不對稱地連接至抽吸口。 In addition to the aforementioned suction nozzle, the present invention also provides a suction-type cleaning device having a suction nozzle, in particular a suction nozzle as described above, wherein the suction nozzle has a suction channel providing a fluid connection to a fan, wherein The end region of the suction channel of the suction channel is in communication with the suction port, which is characterized in that the end region of the suction channel has several flow openings which are in communication with the suction port, and these flow openings are connected in a stepped manner, so that Starting from the suction port, the first flow component passing through the first flow opening to flow into the end region of the suction channel flows in the end region of the suction channel beside the second flow opening in the end region of the suction channel, wherein the first The flow component is added to the second flow component that passes through the second flow opening to flow into the end region of the suction channel, and wherein the suction channel is eccentrically connected to the suction port and corresponds unilaterally to the end region of the suction port Wherein, the end region of the suction channel makes the suction channel asymmetrically connected to the suction port.

本發明之抽吸式清潔設備例如可為僅用於抽吸式清潔之設備，或替代地亦可為組合式的抽吸擦拭設備或具有抽吸功能的其他清潔設備。此吸嘴能以可分離的方式佈置在抽吸式清潔設備之基本設備上，或成為抽吸式清潔設備之固定的組成部分。本發明之抽吸式清潔設備之吸嘴較佳地具有一或數個前述特徵。該等特徵所產生之優點亦相應地適用於本發明之抽吸式清潔設備。 The suction-type cleaning device of the present invention may be, for example, only a device for suction-type cleaning, or may alternatively be a combined suction-wiping device or other cleaning device having a suction function.

The suction nozzle of the suction cleaning device of the present invention preferably has one or more of the aforementioned features. The advantages resulting from these features apply correspondingly to the suction-type cleaning device of the present invention.
