Description

一种气流产生方法及装置 A pneumatic method and apparatus for generating

技术领域 FIELD

[0001] 本发明涉及气体流动,特别涉及一种气流产生的方法及装置。 [0001] The present invention relates to a gas flow, particularly to a method and an apparatus for air flow generated.

背景技术 Background technique

[0002] 风扇由于具有节能、成本低等优势,得到了广泛的应用。 [0002] Since the fan energy-saving, and low cost, has been widely used. 目前,市场上已有多种类型的风扇供选择,如吊扇、落地扇、转页扇、空调扇等,近年来还出现了具备杀菌除臭、负离子净化功能的风扇。 Currently, there are many types on the market of choice for fans, ceiling fan, stand fan, box fan, air-conditioning fan, in recent years has also appeared sterilization deodorant, anion purification fan function.

[0003] 现有电扇的基本组成部件为:带有转动轴的驱动装置,如交流或直流电机,各种不同形状的叶片或翼安装在所述转动轴上,调整驱动装置转动平均速度的调速装置。 [0003] The basic components of the conventional fan is: a drive means having a rotary shaft, such as a DC or AC motor, a variety of different shapes of blades or wings mounted on the rotary shaft, to adjust the average rotational speed of the drive means of the adjustment speed devices. 而在除吊扇外的落地扇、转页扇等风扇中,都还安装了保护罩,防止人、动物或物体触碰到转动的叶片或翼而发生意外。 In addition to the fan stand fan, the fan page like fans are also installed protective cover, to prevent a person, animal or object touching the rotating blades or wings and accidents. 为了满足使用者的要求,可以改变驱动装置的功率、叶片的长度以及在转动轴上的安装角度,从而获得符合使用要求的风速、风量。 In order to meet the requirements of the user, and can change the length of the mounting angle of the rotating shaft power, the blade drive device, so as to obtain wind speed, wind meet use requirements.

[0004] 上述风扇还存在一些不足,如: [0004] The fans are still some deficiencies, such as:

[0005] 1、不便清洗。 [0005] 1, inconvenient cleaning.

[0006] 对于吊在屋顶的吊扇来说,叶片上沾染的灰尘需要爬高才能清洗,非常不便。 [0006] For hanging in the roof of the ceiling fan, the blades on the contaminated dust need to climb in order to clean, very inconvenient. 对于落地扇、转页扇、台扇来说,尤其是叶片的上沾染灰尘清洗需要将防护罩拆下很不方便。 For stand fan, fan page, for desk fan, in particular on the blades need to be cleaned from dust shield removed inconvenient.

[0007] 2、安全性差。 [0007] 2, poor security.

[0008] 尽管有防护罩,但是小孩子还是可以将手指插入到风扇叶片中,容易受伤。 [0008] Although the protective cover, but may be a child or fingers into a fan blade, easily injured.

[0009] 3、体积大,降低了使用者的工作空间。 [0009] 3, bulky, reducing the working space of the user.

[0010] 吊扇叶片的直径多大于lm。 [0010] The diameter of the ceiling fan blade in much lm. 台扇底座的长都超过30cm,占用了较多的桌面,影响了其它物品的摆放,如电脑、文件等。 Long table fan base of more than 30cm, taking up more of the desktop, affecting the placement of other items, such as computers, files and so on.

[0011] 4、在使用上述风扇过程中,旋转的叶片或翼阻挡了自然光或照明光的穿过,长期使用会对使用者的视力构成影响。 [0011] 4, during use of the fan, the rotating blades or wings blocked natural light or illumination light passes through long-term use will affect the user's eyesight configuration.

[0012] 5、叶片或翼的旋转推动空气朝着使用者流动,从而使使用者感到凉爽。 [0012] 5, rotating blades push air flow or wings toward the user, so that the user feels cool. 气流的产生主要是靠叶片或翼的旋转,风扇周边区域的空气也会卷进该气流中,但这种效应非常小,可忽略不计。 Air flow generated mainly by the rotating blade or blades, the peripheral region of the fan air will be drawn into the gas stream, but this effect is very small, negligible.

[0013] 6、噪音大。 [0013] 6, noise. 叶片或翼在旋转过程中,和空气摩擦而发出较大的噪音,转速越高,噪音越大,干扰了使用者的工作和生活。 Blades or wings during rotation, and air friction noisier, the higher the speed, the greater the noise, interfere with the user's work and life.

[0092] 由表格2可见,在内部通道内气体压力不变的情况下,随着在喷嘴上排气口的变大(即排气口面积),风量Q、平均流速都变大,气流的放大倍数反而在变小。 [0092] From Table 2, the internal passage in the case where the gas pressure is constant, with the exhaust port in the nozzle increases (i.e., the exhaust port area), the air volume Q, the average flow rate are increased, the gas flow instead, the magnification becomes small.

[0093] 在表格2中,当内部通道内气流压力为300Pa,排气口的尺寸为0.2mm时产生的风量不能满足需要,但是可以通过加大内部通道内气流的压力或增大排气口面积A,从而满足要求。 [0093] In Table 2, when the internal pressure of 300Pa gas flow passage, the size of the exhaust port is generated when the air volume can not meet the needs of 0.2mm, but by increasing the pressure within the interior gas flow passage or increasing the exhaust port the area A, to meet the requirements. 如压力到1500Pa时,风量Q为0.28m3/s。 When such pressure to 1500Pa, the wind amount Q of 0.28m3 / s. 具体原理请参见实施例2中总结的规律。 Law principle, see in particular Example 2 summarizes embodiment.
