Description

无叶片风扇 Bladeless fan

技术领域 FIELD

[0001] 本实用新型涉及风扇组件,尤其涉及一种用于在室内环境产生气流和增加气流循环的无叶片风扇。 [0001] The present invention relates to a fan assembly, particularly to a gas stream and for generating increased air circulation bladeless fan in an indoor environment.

背景技术 Background technique

[0002] 传统家用风扇通常包括一转动轴、绕该轴转动的一套叶片或叶轮以及用于驱动该叶片或叶轮转动以产生气流的驱动设备。 [0002] The conventional domestic fan typically includes a rotating shaft, the axis of rotation about a blade or vane for driving the blade or vane rotary drive apparatus to produce a gas stream. 气流的流动和循环形成风,热能会通过空气对流得到散发以致使用者能感受到凉爽。 Gas stream flow and circulation air is formed, the heat will be circulated so that the user can feel the cool air by convection. 这种传统家用风扇的缺点是,由旋转的叶片或叶轮产生的气流不能被使用者均勻的感受到,从而使用者会因感受到紊乱的气流而产生被“拍打” 的感觉;同时,叶片占用面积较大,会降低室内亮度。 A disadvantage of this conventional domestic fan, the air flow generated by the rotating blade or vane can not be a uniform user experience, so that the user may feel due to turbulence of air flow generated by "tapping" feeling; while occupying blade larger, reduce the brightness of the room.

[0003] 现有一种无叶片风扇,其包括用于形成气流的基部以及承托设于该基部的环形喷嘴,环形喷嘴限定一开口,且喷嘴包括内部通道以及喷出气流的嘴部,基部包括设于其外壳的空气入口以及叶轮,叶轮的排出部以及喷嘴的内部通道分别与基部内的管道连通。 [0003] A non-conventional fan blade, comprising a base for forming the gas flow and provided on the base portion of the supporting annular nozzle, defining an annular nozzle opening, and the nozzle passage and the nozzle comprises an inner portion of the discharge airflow, the base comprising an air inlet disposed thereon and housing an impeller and an internal portion of the discharge passage of the nozzle communicate with the duct base. 叶轮通过空气入口抽取气体,流经基部内的管道以及喷嘴的内部通道,再通过喷嘴的嘴部喷出气流(主要气流);从喷嘴的嘴部喷出的气流(主要气流)卷吸其周围的空气以形成卷吸气流(次要气流),卷吸气流主要经过喷嘴所限定的开口。 Air drawn through the impeller inlet gas conduit and a nozzle in the base flows through the internal passage, and then discharged gas stream (main stream) through the mouth of the nozzle; from a gas stream (main stream) discharged mouth portion around the nozzle entrainment an intake air stream to form a roll (secondary gas flow), the intake volume flow mainly through the nozzle opening defined. 喷嘴的嘴部所喷出的气流与卷吸气流相结合形成从喷嘴所限定的开口向前发射的总气流,该总气流在喷嘴的直径范围内具有近似的平均速度分布。 A nozzle mouth with the volume of the discharged air intake flow combine to form the total gas flow from a nozzle opening defined by the forward emitted, the total gas flow velocity profile having an average approximate diameter range within the nozzle. 与传统家用风扇相比,现有无叶片风扇向使用者输送的气流具有更低的紊流,使用者可以感受到更加均勻的气流。 Compared with the traditional home fans, fan blades having no conventional turbulence to lower gas flow transporting the user, the user can feel a more uniform flow.

[0004] 但是现有无叶片风扇由于其结构原因而具有以下缺点,其主要包括: [0004] However, the conventional bladeless fan reasons due to its structure has the following disadvantages, which include:

[0005] 一、现有无叶片风扇是通过喷嘴的嘴部喷出气流卷吸其周围空气已形成卷吸气流,喷嘴的嘴部所喷出的气流与卷吸气流相结合形成从喷嘴所限定的开口向前发射的总气流。 [0005] First, prior bladeless fan airflow volume is ejected through the suction mouth of the nozzle is formed around the air intake volume flow, the mouth of the nozzle with the volume of the discharged air intake stream from the nozzles combine to form the total gas flow opening defined by the forward transmission. 喷嘴的嘴部通常设置为一条细缝,然而,仅仅只有一条细缝所产生的气流速度较高,卷吸气流的速度较低,从而造成总气流不够柔和、均勻。 Nozzle mouth is usually set to a slit, however, with only a high velocity gas flow produced a slit, a lower volume of intake air flow rate, resulting in a total gas flow is not enough soft, uniform.

[0006] 二、现有无叶电风扇的环形喷嘴与基部相互固定,且环形喷嘴的俯仰机构设置于基部外。 [0006] Second, the annular nozzle with the conventional non-leaf fan base portion secured to each other, and the annular nozzle is provided on the outer base portion tilt mechanism. 若改变环形喷嘴所喷出气流的上下角度,则需要使基部跟随环形喷嘴一体转动,如使环形喷嘴向前倾,基部则形成一个不规则的形体,多占用空间,与放置于风扇周围的其他物品干涉,且环形喷嘴的枢转角度不够大。 If the angle of the upper and lower annular nozzle change the discharged gas flow, it is necessary to follow the annular nozzle so that the base portion is integrally rotated, so as to lean forward annular nozzle, the base body is formed of an irregular, multi-space, and the other is placed around the fan Item interference, annular nozzle and the pivot angle is not large enough.

[0007] 三、众所周知,空气中存在大量的悬浮尘埃粒子,尘埃素有家用电器杀手之称,它们的存在极大地影响家用电器的性能。 [0007] Third, the well-known, there are a lot of air suspension of dust particles, said dust killer known as household appliances, their presence greatly influences the performance of the household appliance. 空气中悬浮的粒状物质是由固体或液体微粒子所组成。 Particulate matter suspended in the air by the fine particles composed of a solid or liquid. 空气中的悬浮微粒包括固态微粒和液态微粒的多分散的气溶胶。 Air suspension comprising fine solid particles and liquid particles of polydisperse aerosol. 现有无叶片风扇的空气入口未设置空气过滤装置,经过长时间的使用后,空气中的尘埃会粘附在叶轮、基部内的管道、内部通道以及喷嘴的嘴部,尤其是叶轮结构所致其内部结构复杂,难以拆开清洗, 若无空气过滤装置将会粘附过多的尘埃,使带动叶轮的电机负荷增大,减短其使用寿命。 Bladeless fan air inlet conventional air filter device is not provided, after long use, dust in the air may adhere to the impeller, piping, and the internal passage of the nozzle in the nozzle base, due to the particular configuration of the impeller its internal structure is complicated, difficult to open the cleaning, without the air filtering device will be excessive adhesion of dust, the motor load driven by the impeller is increased, shorten its useful life. 同时,过多尘埃会导致喷嘴嘴部的细缝被堵塞,使喷嘴不能喷出气流,从而缩短了风扇的使用寿命。 At the same time, dust may lead to excessive nozzle slit nozzle portion is blocked, so that the nozzle can not discharge the gas flow, thereby shortening the life of the fan. [0008] 综上可知,现有,在实际使用上,显然存在不便与缺陷,所以有必要加以改进。 [0008] To sum up, the conventional, practical use, it is clear there is an inconvenience and defects, it is necessary to be improved. 实用新型内容 SUMMARY
