Description

风扇 fan

技术领域 FIELD

[0001] 本发明涉及一种风扇装置。 [0001] The present invention relates to a fan apparatus. 特别地,但非排他地,本发明涉及一种室内风扇,例如台式风扇,用以在房间、办公室或其它室内环境中产生空气循环和空气流。 In particular, but not exclusively, the present invention relates to an indoor fan, such as desktop fans, air circulation and for generating an air flow in a room, office or other indoor environment.

背景技术 Background technique

[0002] 很多类型的室内风扇已为我们所知。 [0002] Many types of indoor fan has been known to us. 通常地,传统风扇包括单独的一套安装成绕轴线旋转的叶片或翼,以及绕轴线安装以使整套叶片旋转的驱动装置。 Generally, a conventional fan to include a single set of installed blades which rotate about an axis or wings, mounted about an axis and drive means for rotating the blade package. 可以得到各种尺寸和直径的室内风扇,例如,吊扇直径可以为至少lm,且通常以悬吊于天花板上的方式安装,并定位成向下提供气流以及使房间降温。 You can be of various sizes and diameters of the indoor fan, for example, a ceiling fan can be at least a diameter LM, and is generally suspended from the ceiling mounted and positioned to provide air flow and causing the room to cool down.

[0003] 另一方面,台式风扇的直径一般约为30cm,并且通常可以随意放置且可携带。 [0003] On the other hand, desk fans diameter is generally about 30cm, and generally can be placed freely and portable. 在标准台式风扇的配置中,单独的一套叶片靠近使用者安置,并且风扇叶片的转动在房间或向房间的一部分提供朝向使用者的向前的空气流。 In standard desk fan configuration, the single set of blades is disposed closer to the user, and the rotation of the fan blade, or to provide an air flow towards the user to the forward part of the room in the room. 其它类型的风扇可置于地板上或安装到墙上。 Other types of fans may be mounted on the floor or a wall. 空气的运动或循环产生所谓的“风冷”或微风,因此,使用者在热量通过对流和蒸发被驱散时能感受到凉爽效果。 Circulating air movement or so-called "air" or breeze, and therefore, the user is dissipated as heat by convection and evaporation can feel the cooling effect. 诸如在USD103,476和US1,767,060中公开的风扇适于放置在桌子或台子上。 Such as disclosed in USD103,476 US1,767,060 and the fan is adapted to be placed on a desk or table. US1,767,060公开了一种具有摇摆功能的台式风扇,该功能的目的在于提供相当于两个或更多个现有技术风扇所能提供的空气循环能力。 US1,767,060 discloses a fan having a swing desktop function, purpose of this feature is the ability to provide an air circulation equivalent to two or more prior art fans can provide.

[0004] 这种类型的装置的缺点是风扇的旋转叶片产生的空气流的向前流动会让使用者感到不均匀。 Disadvantage [0004] This type of device is the rotating blades of the fan air generated by the forward flow of the stream will allow users to feel uneven. 这是由于通过叶片表面或风扇外端表面的变化产生的。 This is because the change in the blade surface or the outer end surface of the fan generated. 不均匀或“波浪式”的气流会使人感到一连串的脉冲气流或阵风,并且可能很嘈杂。 Uneven or "wave-like" airflow will make people feel a series of pulses of air or wind gusts, and can be very noisy. 另外的缺点是风扇产生的凉爽效果随着与使用者距离的增大而减弱。 A further disadvantage is the cooling effect produced by the fan with increasing distance from the user is weakened. 这就意味着风扇必须紧密靠近使用者放置才能让使用者得到风扇的益处。 This means that the fan must be placed in close proximity to the user in order to allow users to get the benefit of the fan.

[0005] 在室内环境中,由于空间限制,有必要使设备尽可能小巧紧凑。 [0005] In the indoor environment, due to space limitations, it is necessary to make the device compact as possible. 不期望部件从设备中凸出或让使用者触碰到风扇的任何运动部件,例如叶片。 Projecting member or undesirable to allow a user to touch any moving parts of the fan from the device, such as a blade. 有些设备具有安全装置,例如环绕叶片的隔离罩或笼罩,以防使用者被风扇的运动部件弄伤。 Some devices having a safety device, such as a cage surrounding the blades or shrouded, to prevent users hurt by the moving parts of the fan. USD103, 476展不了一种环绕叶片的隔离罩,然而,被隔离的叶片部件很难清理。 USD103, 476 not show one kind of cage around the blades, however, it is difficult to clean isolated blade member.

[0006] 在”2,488,467、”2,433,795和见56-167897中公开了其它类型的风扇或循环器。 [0006] In the "2,488,467," and 2,433,795, see in 56-167897 discloses other types of fan or circulator. US2,433,795中的风扇在旋转笼罩中具有旋转槽而不是风扇叶片。 US2,433,795 rotary drum having a fan enveloped in a rotary instead of fan blades. US2,488,467中公开的循环风扇从一系列的喷嘴中释放气流,并且具有很大的基座,该基座包括用于产生气流的电机和送风机或风扇。 US2,488,467 disclosed a series of circulation fans released from the nozzle gas stream and has a large base, the base including a motor for generating the air flow and the fan or blower.

[0007] 并不总是能够将如上所述的风扇定位成靠近使用者,因为庞大的外形和结构意味着风扇要占用使用者大量的工作区域。 [0007] As described above can not always be positioned close to a user of the fan, because of the huge shape and structure mean that the fan takes up a lot of work the user area. 尤其是当风扇置于或接近书桌时,扇体或基座减小了对于文书区、计算机或其它办公设备而言可占据的面积。 Particularly when placed in or near the desk fan, fan or base reduces the area for the region instruments, computers or other office equipment can occupy. 通常多个设备必须安放于同一区域,靠近电源提供点,且靠近其它设备,以方便连接和减少运行成本。 Typically the plurality of devices must be located in the same area, close to the power supply point, and close to the other devices to facilitate the connection and reduce operating costs.

[0008] 放在桌子上的风扇的外形和结构不仅减小了使用者的工作空间,而且也遮挡了射向桌子的自然光(或来自人造光源的光)。 [0008] on the table shape and structure of a fan not only reduces the working space of the user, but also blocked the natural light (or light from artificial light sources) directed to the table. 另外,紧张的工作或阅读需要有良好的书桌光线,并且良好的光线能够减小由于长时间工作在光线较弱的环境下所带来的眼睛疲劳以及相关健康问题。 In addition, the intense work or reading desk requires good lighting and good lighting can be reduced due to prolonged work in low light environment caused by eye strain and related health problems.

发明内容 SUMMARY

[0010] 根据本发明的第一方面,提供了一种产生空气流的无叶片风扇装置,该风扇装置包括安装在基座壳体上的喷嘴以产生通过喷嘴的气流,该喷嘴包括用于接收来自底座的气流的内部通道和排气口,通过该排气口喷射气流,喷嘴基本上关于轴线正交地延伸来限定开口,风扇装置外部的空气通过开口被从排气口喷射的气流抽吸,其中,喷嘴和基座中的每一个在所述轴线方向上都具有一深度,其中,基座深度不超过喷嘴深度的两倍。 [0010] According to a first aspect of the present invention, there is provided a bladeless fan means for generating an air flow, the fan apparatus comprises a nozzle mounted on the base housing to generate an air flow through the nozzle, which nozzle comprises means for receiving an internal passage and an exhaust port of the airflow from the base, through which the jet stream discharge port, the nozzle extending substantially orthogonally about an axis to define an opening, the external air flow through the air fan device is ejected from the opening of the suction exhaust port wherein the nozzle and the base each in the axial direction has a depth, wherein the depth of the base is not more than twice the depth of the nozzle.

[0011] 优选地,基座的深度在10mm到200mm的范围内,更优选的是150mm左右。 [0011] Preferably the depth of the base in the range of 10mm to 200mm, and more preferably about 150mm. 在这种配置中,优选的是,风扇装置具有从远离喷嘴的基座端部延伸到远离基座的喷嘴端部的高度,以及垂直于高度的宽度,该高度与该宽度都与所述轴线垂直,并且其中,基座的宽度不超过喷嘴的宽度的75%。 In this configuration, it is preferable that the fan device has a width extending from a base end away from the nozzle to the height of the end of the nozzle remote from the base, and perpendicular to the height of the height to the width of both said axis vertical, and wherein the width of the base is no more than 75% of the width of the nozzle.

[0012] 根据本发明的第二方面,还提供了一种产生空气流的无叶片风扇装置,该风扇装置包括安装在基座壳体上的喷嘴以产生通过喷嘴的气流,该喷嘴包括用于接收来自底座的气流的内部通道和排气口,通过该排气口喷射气流,喷嘴基本上关于轴线正交地延伸来限定开口,风扇装置外部的空气通过开口被从排气口喷射的气流抽吸,该风扇装置具有从远离喷嘴的基座末端延伸到远离基座的喷嘴末端的高度和垂直于高度的宽度,该高度与该宽度都与所述轴线垂直,并且其中,基座的宽度不超过喷嘴的宽度的75%。 [0012] According to a second aspect of the present invention there is also provided a bladeless fan means for generating an air flow, the fan apparatus comprises a nozzle mounted on the base housing to generate an air flow through the nozzle, the nozzle comprising a receiving from the interior passage and the exhaust port of the base stream, the jet stream through an exhaust port, the nozzle extending substantially orthogonally about an axis to define an opening, the external air through the opening of the fan device is ejected stream smoke from the exhaust port suction, the fan device having a width extending from the base away from the nozzle tip to the nozzle tip vertical height and away from the base in the height, both the height and the width is perpendicular to the axis, and wherein the width of the base is not more than 75% of the width of the nozzle.

[0014] 在以下关于风扇特别是关于优选实施方式的风扇的说明中,术语“无叶片”(bladeleSS)用来描述气流从风扇组件中向前释放或喷出而不需使用叶片的设备。 [0014] In the following description about the fan particular embodiment of the fan of the preferred embodiment, the term 'bladeless' (bladeless) used to describe airflow discharged or released from the fan assembly without the use of forward blade device. 通过该定义,无叶片风扇装置可以被看作是具有没有叶片或翼的输出面或发射区,气流沿大致朝向使用者的方向从中释放或发射出去。 By this definition a bladeless fan output device may be regarded as not having a surface-emitting region or blade or vane, airflow direction substantially toward the user's release or emitted therefrom. 无叶片风扇可以藉由多种源装置或发生装置提供主要的空气来源来产生气流,例如泵、发电机、电机或包含发动机转子和叶轮片等旋转设备的其他流体输送装置。 Bladeless fan may provide the main source of air by a variety of sources or generating means means to generate an air flow, such as pumps, generators, motors or other fluid engine comprising a rotor and an impeller rotating equipment such as sheet conveying device. 通过电机产生的空气量使得空气气流从房间或风扇装置外的环境中穿过内部通道到达喷嘴,然后从排气口喷出。 The amount of air produced by a motor so that air flow through the inner passage from the room or environment outside the fan device to the nozzle, and then ejected from the exhaust port.

[0015] 因此,关于无叶片风扇组件的说明的目的不在于延伸至动力源和零部件等风扇次要功能所需部件,比如电机。 [0015] Accordingly, an object of Notes bladeless fan assembly is not extended to the power source and the secondary fan functions other components required components, such as motors. 风扇次要功能的例子包括照明、调节和风扇的摆动。 Examples of secondary fan functions include lighting, adjustment and oscillating fan.

[0016] 优选地,风扇装置的基座宽度范围为喷嘴宽度的65%到55%,更为优选地为喷嘴宽度的50%左右。 [0016] Preferably, the width of the base, the fan device 65 for the nozzle width to 55%, more preferably about 50% of the width of the nozzle. 在优选的实施方式中,风扇装置的高度范围为300mm到400mm,更为优选地为350mm左右。 In a preferred embodiment, the height range of the fan device is 300mm to 400mm, more preferably about 350mm. 风扇装置的优选外形和尺寸在产生来自风扇装置的让使用者感到凉爽的适量气流的同时也使装置紧凑。 Preferably the shape and size of the fan apparatus make users feel the cool air flow amount from the fan while generating means also means compact.

[0017] 优选地,基座大致为圆柱形。 [0017] Preferably, the base is substantially cylindrical. 这样的配置使得具有紧凑基座的风扇装置看起来整洁且一致。 Such a configuration enables a compact fan apparatus having a base look neat and consistent. 这种整洁的设计很受使用者和消费者的欢迎和青睐。 This clean design popular with users and consumers and favor. 另外,当放置于桌或工作台上时,这种风扇装置的基座占用的桌面面积少于其它已有风扇装置所占据的空间。 Further, when placed on the desk or table, the base of this fan device occupied area of ​​the desktop space other than occupied by the existing fan devices. 喷嘴占用桌面上方远离基座延伸开来的空间,而不遮挡桌面或妨碍使用者接近桌面。 Desktop footprint nozzle extending from the base away from the open to the top, without obstructing the desktop or obstruct user access the desktop.

[0041] 以上描述的风扇装置100以下述方式运行。 The fan apparatus [0041] 100 described above operates in the following manner. 当使用者从多个按钮20中作出合适的选择以操作或启动风扇装置100时,传送一信号或其它讯息以驱动电机22。 When the user to make the appropriate selection from the plurality of buttons 20 to operate or activate the fan device 100, transmits a signal to the drive motor or other post 22. 由此电机22被启动,并且空气经由空气进口24被抽入到风扇装置100中。 Whereby the motor 22 is actuated, and the air inlet 24 via the air 100 is drawn into the fan unit. 在优选的实施例中,空气以大约每秒20到30升的速度被抽入,优选地为大约271/s (升每秒)。 In a preferred embodiment, the air is about 20 to 30 liters per second, the speed is drawn into, preferably (liters per second) is from about 271 / s. 空气穿过外罩18并沿图3的箭头F所示的路径到达叶轮30的进口34。 Air inlet through the housing 18 and to the impeller 30 along the path shown by arrow 34 in FIG. 3 F. 从扩散器32的出口36离开的气流和叶轮30的排气被分为两股气流,这两股气流以相反方向穿过内部通道10。 From the exhaust outlet 32 ​​of the diffuser 36 and the gas flow exiting the impeller 30 it is divided into two streams, the two streams through the inner passage 10 in the opposite direction. 气流进入排气口12时被压缩,并且在排气口12的出口44处被进一步压缩。 Compressed air flow into the exhaust port 12 and exhaust port 44 at the outlet 12 is further compressed. 压缩在系统中产生压力。 A pressure in the compression system. 电机22产生的穿过喷嘴16的气流具有的压力至少为400kPa。 Gas flow through the nozzle 16 has a motor 22 generates a pressure of at least 400kPa. 产生的气流克服压缩产生的压力,并且气流作为主气流通过出口44排出。 Against the pressure of the compressed air flow generated generated as the primary air flow and the air flow is discharged through the outlet 44.

[0042] 主气流的输出和喷射在空气进口24a、24b处产生低压区域,并具有将额外空气抽入风扇装置100的效果。 [0042] and the output of the main gas flow creates a low pressure region at the ejection of the air inlet 24a, 24b, and has the effect of additional air into the fan device 100. 风扇装置100的操作导致高气流穿过喷嘴I并流出开口2。 Operation of the fan device 100 results in a high air flow through the nozzle outlet opening and I 2. 主气流被引导流过柯恩达表面14和扩散器表面46,并通过柯恩达效应被放大。 Primary air flow is directed through the Coanda surface 14 and the diffuser surface 46, and is amplified by the Coanda effect. 副气流通过卷吸来自外部环境的、尤其是来自出口44周围区域和喷嘴I的外边缘附近的空气而产生。 Secondary flow by entrainment from the external environment, particularly from the surrounding air and the outer edge of the region 44 near the nozzle outlet to produce I. 被主气流卷吸的部分副气流也可以被引导而通过扩散器表面46。 The primary air flow is drawn secondary flow volume portion may be guided by the diffuser surface 46. 该副气流穿过开口2,在开口2处与主气流结合以产生从喷嘴I向前射出的总气流。 The secondary flow through the opening 2, the opening 2 in conjunction with the primary air flow to produce a total air flow emitted from the nozzle forwardly I.

[0043] 卷吸和放大的结合使得来自风扇装置100的开口2的总气流大于从在靠近喷射区域没有诸如柯恩达或放大表面的风扇装置输出的气流。 [0043] The combination of entrainment and amplification such that the total gas flow from the fan device 100 is not an opening greater than 2, such as a Coanda air flow in the fan means outputs an enlarged surface area or near the ejection from.

[0044] 产生的放大和层流类型的气流使得持续的气流从喷嘴I处被引导朝向使用者。 [0044] and the flow amplification type layer such that the continuous air flow generated air flow is directed towards a user from the nozzle at I. 在优选实施例中,从风扇装置100射出的空气质量流量至少为4501/s,优选在6001/s到7001/s的范围内。 In a preferred embodiment, the apparatus 100 is emitted from the fan air mass flow rate of at least 4501 / s, preferably at 6001 / s in the range of 7001 / s is. 距离使用者高达三倍喷嘴直径(即约1000到1200mm)距离处的流量约为400到5001/s。 Up to three times the nozzle diameter from the user (i.e., to about 1200mm 1000) at a flow rate of from about 400 to 5001 / s. 总气流具有的流速约为3到4m/s (米每秒)。 Total gas flow having a flow rate of about 3 to 4m / s (meters per second). 通过减小柯恩达表面14和X轴之间的包角可以获得更高的速度。 By reducing the wrap angle between the Coanda surface 14 and the X-axis can be obtained at a higher speed. 小的角度使得总气流以一种更加集中和更有导向性的方式被喷射。 Small angle such that the total gas flow in a more concentrated and more oriented manner ejection. 这种类型的气流趋向于以更高的速度和更小的质量流量被喷射。 This type of air flow tends to be at a higher speed and smaller mass flow is ejected. 反过来,通过增加柯恩达表面和轴之间的夹角可以获得更大的质量流量。 Conversely, greater mass flow can be obtained by increasing the angle between the Coanda surface and the axis. 这样,喷射的气流的流速减小,但产生的质量流量增加。 Thus, the flow rate of injected air flow is reduced but the mass flow generated increases. 因此,可以通过改变柯恩达表面和X轴之间的包角来改变风扇装置的性能。 Thus, performance of the fan means may be changed by changing the wrap angle between the Coanda surface and the X-axis.
