Description

用于真空吸尘器的马达、风扇和过滤器装置 A motor for a vacuum cleaner, a fan and a filter means

技术领域 FIELD

本发明涉及一种用于真空吸尘器的马达、风扇和过滤器装置以及包括这种马达、风扇和过滤器装置的真空吸尘器。 The present invention relates to a motor, a fan and a filter device for a vacuum cleaner and a vacuum cleaner including such a motor, a fan and a filter device.

背景技术 Background technique

众所周知真空吸尘器主要用于收集尘垢,尽管能够收集液体的干 The vacuum cleaner is mainly known for collecting dust, although it is possible to collect the liquid dry

湿变型(wet-and-dry variant)也是已知的。 Wet type (wet-and-dry variant) are also known. 通常,真空吸尘器用于家庭环境中,尽管真空吸尘器也可用于诸如工地的其它环境中。 Typically, a vacuum cleaner for home environment, although the vacuum cleaner can also be used in other environments, such as site. 通常, 它们是电动的,因此包括电动机和连接到电动机输出轴的风扇、用于污浊空气的入口、用于洁净空气的出口以及用于灰尘、污垢并且也可能液体的集尘室。 Typically, they are electrically powered and therefore includes a motor and an output shaft connected to the motor of the fan, the inlet for dirty air, an outlet for clean air and dust, dirt and possibly also liquids baghouse. 可以通过主线电源为马达提供电功率,在这种情况下,真空吸尘器将进一步包括可通过可拆卸和可替换的电池组或者通过一个或多个内装式的可充电电池提供的电力电缆,在这种情况下, 该真空吸尘器将进一步包括一些诸如插头的装置,用于将真空吸尘器连接到再充电单元。 By Ma Dati mains supply to supply the power, in this case, the vacuum cleaner further includes a power cable may be provided through one or more built-in rechargeable batteries by a removable and replaceable battery pack, or, in which case, the vacuum cleaner will further include some means, such as a plug, for connecting the vacuum cleaner to a recharging unit. 当从这些源之一为真空吸尘器提供电功率时,电动机驱动风扇以沿气流路径吸入污浊空气通过污浊空气入口,然后经由集尘室到达洁净空气出口。 When the vacuum cleaner is supplied with electric power from one of these sources, the motor driving the fan intake air flow path along the dirty air through a dirty air inlet, a clean air outlet and then to the dust collecting chamber via.

还将某一装置设置在沿着气流通道的某点处,所述装置用于分离出污浊空气中所夹带的尘垢(以及也可能的液体)并将这些尘垢沉淀在集尘室中。 Also a means is provided at some point along the gas flow passage, means for separating the dirt (and possibly also liquids) entrained with the dirty air and the dust precipitated in the dust collecting chamber. 这种分离装置可包括一个或多个过滤器和/或气旋分离设备。 Such separation means may comprise one or more filters and / or a cyclonic separation device. 传统地,如果分离装置包括过滤器,则马达、风扇和过滤器具有如图l中示意性表示的装置。 Conventionally, if the separating means comprises a filter, the motor, fan and filter apparatus shown in Figure l has a schematically represented. 从图l中可以看出,己经经由污浊空气入口进入真空吸尘器的污浊空气通过过滤器30从区域P流动到区域Q。 As can be seen from Figure l, has entered the vacuum cleaner via the dirty air inlet dirty air through the filter 30 flows into the region from the P region Q. This

将污浊空气中所夹带的尘垢(以及也可能的液体)分离出来,因此已过滤材料保留在区域P中。 The dirty air entrained dirt (and possibly also liquids) separated, thus filtered material remains in the region of the P. 如果像通常那样将过滤器30本身设置在收集室内,则保留在区域P中的已过滤材料就积聚在那里。 If the filter 30 itself, as provided in the collection chamber is maintained in the region P has accumulated on the filter material there as usual. 然后洁净空气从 And clean air from

过滤器30另一侧的区域Q通过形成在壁40中的格栅42流动到第三区域R,其中过滤器30安装在壁40上。 The other side of the grating region 30 by the Q filter 40 is formed in the wall 42 flows to the third region R, where the filter 30 is mounted on the wall 40. 虽然可设置附加的过滤器,但是格栅42通常不具有过滤效果。 Although additional filters may be provided, but the grid 42 generally do not have filter effects. 相反它的主要目的是防止使用者接近安装在马达10的马达输出轴12上的风扇20,当通过电端子14、 16为马达10 提供电力时,马达10通过真空吸尘器吸入空气。 Instead its primary purpose is to prevent user access to the fan mounted on the motor output shaft 12 of the motor 10 is 20, when the motor 10 provides power through electrical terminals 14, 16, the motor 10 draws air through the vacuum cleaner. 如图1所示,风扇20 是一叶轮,其轴向向其叶面吸入空气并切向排出空气,然后空气从此处流动到真空吸尘器的洁净空气出口。 1, the fan is an impeller 20, an axial intake air and its tangential exhaust air foliage, and then air flows from here to the clean air outlet of the vacuum cleaner. 具有图l的传统马达、风扇和过滤器的可手持真空吸尘器的实例也以本申请人的名义在欧洲专利公开No. EP 1 523 916 A中进行了说明。 FIG example of a conventional motor having a l, the fan and filter can be hand held vacuum cleaner is also the name of the Applicant discloses No. EP 1 523 916 A has been described in the European patent.

因此上述的马达、风扇和过滤器的传统装置形成了三个分隔区域P、 Q和R,其中第二区域,区域Q实际上是"死"空间。 Thus the conventional motor apparatus described above, the fan and the filter is formed of three spaced regions P, Q and R, wherein the second region, the region Q is actually "dead" space. 换句话说,区域P可用于为所述的过滤材料提供集尘室,而区域R容纳马达10和风扇20, 区域Q仅占用空间而不实现任何目的。 In other words, the region P may be used to provide the baghouse filter material, and the receiving area R 10 and fan motor 20, only with a space area Q achieved without any purpose. 在一方面,过滤器30应具有尽可能大的表面面积以提高它的过滤效果,这往往会增加区域Q的尺寸。 In one aspect, the filter 30 should have as large surface area to enhance its filtering effect, which tends to increase the size of the area Q. 这恰恰是为什么通常避免在格栅42的位置横过风扇20的表面设置平坦 This is precisely why generally transverse to avoid flat surface of the fan 20 is provided at a position of the grid 42

过滤器的原因。 The reason the filter. 尽管这可将区域Q完全省去,但是由于在气流路径中形成瓶颈,这种小的过滤器也会严重地降低真空吸尘器的效率。 While this area may be omitted altogether Q, but since the air flow path formed in a bottleneck in such small filter can seriously reduce the efficiency of the vacuum cleaner. 此外, 为了进一步提高过滤器30的效率,经常将过滤器设置成圆柱形或截头圆锥形形状。 Further, in order to further improve the efficiency of the filter 30, the filter is often disposed in a cylindrical or frusto-conical shape. 这种形状促使区域P中的污浊空气在通过过滤器30之前绕过滤器30旋动,这具有在旋风分离器中的离心力作用下背离过滤器30 向外掷出尘垢颗粒的效果。 This shape causes dirty air P in the region before the filter 30 by rotating around the filter 30, which has the effect of filter 30 facing away from the centrifugal force in the cyclone dust particles thrown outwardly. 另一方面,然而,如果必须为过滤器30提供较大的表面面积或这样的形状,那么为了节省空间并减小区域Q尺寸,将风扇20和可能的同样部件或整个马达10插入到区域Q中的可选方案也是不可预期的,因为这将会妨碍从风扇20切向排出的空气流出到真空吸尘器的洁净空气出口,而是使得由风扇排出的空气撞击过滤器30的内表面,从而与通过过滤器30流入的洁净空气相对,并再次严重地降低过滤操作的效率。 On the other hand, however, if it is necessary to provide a large surface area or a shape of the filter 30, then in order to save space and reduce the size of the area Q, the fan 20 and possibly the same components or the entire region of the motor 10 is inserted into the Q the alternative is unexpected because it would interfere with the clean air flows out from the outlet 20 to the tangential fan air discharged into the vacuum cleaner, but such that the air discharged by the fan 30 strikes the inner surface of the filter, and thus in contrast, and again seriously reduce the efficiency of the filtering operation by the filter 30 into the clean air of. 因此图l中示出的马达、风扇和过滤器的传统装置在其空间的使用方面是低效的,但是却没有明显的能够解决其本身存在的这个问题的解决方法。 Thus the conventional apparatus shown motor fan and filter in FIG l is inefficient in its use of space in terms of, but no obvious solution to solve this problem which is inherent. 在紧凑型或手持真空吸尘器中,这种低效的空间使用是特别不合需要的,而在这种类型的真空吸尘器中,空间的有效使用是相当重要的,任何浪费的空间都将必然增加所述真空吸尘器的整体重量, 而不会带来任何与其相当的益处。 In the compact or handheld vacuum cleaner, this inefficient use of space is particularly undesirable in this type of vacuum cleaner, the effective use of space is important, any wasted space will necessarily increase in said overall weight of the vacuum cleaner, without bringing any benefit equivalent thereto.

发明内容 SUMMARY

因此本发明的目的是提供一种用于真空吸尘器的马达、风扇和过滤器装置,该装置能够比图l中所示的传统装置更好地利用空间。 Therefore object of the present invention is to provide a vacuum cleaner motor, a fan and filter means for the apparatus can be a conventional device than shown in Figure l better use of space. 本发明的另一目的是提供一种特别适合用于紧凑型或手持真空吸尘器中的马达、风扇和过滤器装置。 Another object of the present invention is to provide a particularly suitable for use in compact handheld or motor, the fan and the filter means in a vacuum cleaner. 本发明的又一目的是提供一种包括这种马达、风扇和过滤器装置的真空吸尘器。 A further object of the present invention is to provide a vacuum cleaner comprising such a motor, a fan and a filter device.

因此,在第一方面,本发明提供一种用于真空吸尘器的马达、风扇和过滤器装置,该装置包括:马达;风扇,该风扇连接到马达的输出轴并具有轴向空气入口;以及过滤器;其中,将风扇设置为使其轴 Thus, in a first aspect, the present invention provides a vacuum cleaner motor, a fan and filter means, the apparatus comprising: a motor; a fan connected to an output shaft of the motor and having an axial air inlet; and a filter ; wherein the fan is disposed to its axis

向入口面对马达;并且马达被容纳在过滤器中。 The inlet face of the motor; and the motor is housed in the filter. 这种装置使得能够沿与传统装置相反的方向将所述马达设置在过滤器中,从而使得来自过滤器的洁净空气在遭遇风扇之前被吸入马达。 Such a device enables the device along a direction opposite to said motor is disposed in a conventional filter, so that clean air is sucked from the filter before the onset of the fan motor. 因此通过在马达输出轴上从马达的输出轴伸出,仍可将风扇设置在过滤器外部,使得由风扇排出的空气不会受到过滤器的阻碍,并且仍可容易地流向真空吸尘器的洁净空气出口。 Therefore, by projecting the output shaft of the motor from the output shaft of the motor, the fan can still be provided outside of the filter, so that the air discharged by the fan is not obstructed filter and still be easily clean air flow vacuum cleaner Export. 此外,由于在来自过滤器的洁净空气遭遇风扇之前被吸入马达,所以还提供了利用来自过滤器的空气冷却马达的有益副作用,而不像图l的传统装置那样,在图l的传统装置中如果通过由风扇排出的空气对马达进行了冷却,那么空气从风扇的流出将不得不改变路线以越过马达。 Further, since the motor is sucked before the clean air from the filter fan encounters, it is also provided for cooling the motor by the air from the filter beneficial side effects, unlike the conventional apparatus of FIG. L as in the conventional apparatus in Figure l If the motor is cooled by the air discharged by the fan, the air flowing out of the fan will have to change the route from the motor to cross. 这将需要气流改变方向,从而将空气动力学阻力引入到气流中并降低了真空吸尘器的整体效率。 This will require the air flow to change direction, so that the gas stream is introduced into the aerodynamic drag and reducing the overall efficiency of the vacuum cleaner. 与此相反,本发明的马达、风扇和过滤器装置不需要使由风扇排出的空气改变线路,并且由于马达容纳在过滤器中,所以实现了空间的有效使用,并且因此特别适合用于紧凑型或手持真空吸尘器中。 In contrast to this, the motor according to the present invention, a fan and a filter device does not require changing the line of the air discharged by the fan, and since the motor housed in the filter, so to achieve an effective use of space, and is therefore particularly suitable for compact or handheld vacuum cleaner.

本发明的马达、风扇和过滤器装置还具有明显的优点:鉴于图l 的传统装置中的风扇是切向排出空气的叶轮,而在本发明的马达、风扇和过滤器装置中的风扇可以是叶轮或螺旋桨,后者从与通过风扇将空气轴向吸入的表面相对的一侧轴向排出空气。 The motor of the present invention, a fan and a filter device also has significant advantages: As a conventional apparatus of Figure l in the fan is tangential impeller to the discharge air, and the fan motor, the fan and the filter device according to the present invention may be impeller or propeller, and by which the axial fan air intake surface opposite axial side of the exhaust air. 这是因为在传统装置中,风扇的背面受到马达的阻碍,因此从风扇流出的空气必须切向引出,而在本发明的马达、风扇和过滤器装置中,风扇的背面是不受遮挡的,使得来自风扇的空气既能够如在叶轮中那样切向排出又能如在螺旋桨中那样轴向排出。 This is because in the conventional apparatus, the back of the fan motor is obstructed, thus flowing out from the air fan to be drawn out tangentially, while in the motor, the fan and the filter device according to the present invention, the back of the fan is not blocked, as can be cut so that both air from the fan impeller to the discharge as such but as in the propeller discharged axially. 这为包括这种马达、风扇和过滤器装置的真空吸尘器中的气流的总体设计提供了极大的多功能性,从而能够自由地引导由风扇排出的空气。 This provides great versatility in the overall design of the vacuum cleaner comprises a gas stream such a motor, a fan and a filter device, thereby to freely guide the air discharged by the fan.

本发明的马达、风扇和过滤器装置还可包括设置在马达和过滤器之间的可透气壳体。 Motors, fans and filters of the present invention may further comprise means disposed between the motor and the gas permeable filter housing. 因此,如果例如为了清洗或替换它过滤器是可拆卸的,则壳体可防止使用者接近马达和风扇,但是空气仍然能够通过壳体从过滤器到达风扇。 Thus, if, for example to clean or replace the filter which is removable, it is possible to prevent user access to the housing and a fan motor, but is still able to reach the air from the fan through the filter housing. 可选地马达壳体可以是不透气的,在这种情况下,装置还可包括设置在马达和风扇之间的格栅,马达输出轴穿过该格栅。 Alternatively, the motor housing may be gas impermeable, in which case, the apparatus further comprising a grid disposed between the motor and the fan, the motor output shaft passing through the grate. 因此,不透气的壳体完全防止使用者接近马达的电部件,但是空气仍可通过格栅从过滤器到达风扇。 Thus, hermetic housing completely prevent user access to the electric motor means, but still air from the filter to the fan through the grille. 对于使用者来说,这种可选方案比可透气的马达壳体更安全,但也具有相应的缺点,即不能通过来自过滤器的空气对马达进行冷却。 For the user, this alternative breathable safer than the motor housing, but also has corresponding disadvantages, i.e., not through an air filter from the motor is cooled.

优选地,马达的输出轴从过滤器内部延伸,并且输出轴的一端被安装在轴承上,该轴承设置在与马达相反的风扇侧上。 Preferably, the output shaft of the motor extends from the inside of the filter, and the output end of the shaft is mounted on a bearing disposed on the opposite side of the fan motor. 这样,通向风扇的轴向入口不会受到马达或轴承的阻挡,这改进了进入风扇的气流 Thus, leading to the axial inlet of the fan motor or bearings will not be blocked, which improves the air flow into the fan

的空气动力学效率,而延长的马达输出轴通过轴承支承,当风扇旋转时,这可防止延长的马达输出轴由于风扇中的任何潜在不平衡而振动。 The aerodynamic efficiency, and the motor output shaft extending through the bearing, when the fan is rotated, which can prevent the extension of motor output shaft since the fan of any potential imbalance vibration.

在第二方面,本发明还提供了一种根据本发明第一方面的包括马达、风扇和过滤器装置的真空吸尘器。 In a second aspect, the present invention also provides a vacuum cleaner comprising a motor, a fan and a filter device according to a first aspect of the present invention. 优选地,该真空吸尘器是手持真空吸尘器,该手持真空吸尘器能够最大化地利用这种马达、风扇和过滤器装置所提供的节省空间。 Preferably, the hand vacuum cleaner is a vacuum cleaner, the hand vacuum cleaner to maximize the use of such a motor, the fan and the space-saving filter device is provided.
