The technical details, for those who are more curious, are like this; the base contains and impeller that draws air into the base, that air is then forced up into the loop amplifier and is accelerated through the rotating ring also called and annular aperture , thereby creating a jet of air. The air then passes over a 16 degree airfoil shaped ramp, channeling its direction. Then the surrounding air is drawn into the airflow - the resulting airflow is amplified by 15 times 15x , equaling liters of air movement every second.
Second, the questions often arises, what are its the advantages over a traditional bladed fan? The Air Multiplier has six specific advantages over the traditional fan. The Jetstream Bladeless Fan is the ultimate in air distribution.
Air is drawn in from its surroundings and quietly driven through the bladeless design. The fan features a touch-tilt adjusting and a degree oscillating head allowing you to direct the air exactly where you need it.
Using Air Multiplier technology, air is accelerated through an annular aperture, drawing in surrounding air to project a high-velocity cooling airflow. Jetstream Bladeless Fan enhances the quality of air in your home. Unlike traditional blades that collect and blow dust, dirt, pollen around the home, the JetStream Bladeless fan minimizes airborne germs and is extremely easy to clean.
Dyson Bladeless Fan is designed with 10 air flow settings and draws in surrounding air for less turbulence. It is powerful, yet noiseless and energy-efficient. The maximum speed of the Jetstream Bladeless Fan is rpm. Dyson does not reveal any information about maximum speed. It works well but needs to be made with a remote control. The 90 degree swing means air will be uniformly distributed around the house efficiently while you can also use this versatile fan on the walls to get better results.
You also have the option of Custom Control, which lets you adjust the air flow in your surroundings to suit your personal tastes. Options are endless when you use this fan at home and your comfort and that of your loved ones will be well looked after. And the dimmer switch control lets you adjust air flow beyond regular three speeds you get otherwise.
The JetStream fan died after using it last summer and part of this one. The utility model provides a bladeless fan which comprises a nozzle and a generating device used for generating air flow passing through the nozzle, wherein the nozzle comprises an annular cavity and exhaust outlets; the annular cavity is approximately symmetrical relative to an axis; the bladeless fan is characterized in that the nozzle further comprises a flat cavity; the annular cavity surrounds the flat cavity; the periphery of the flat cavity is communicated with the annular cavity; both the flat cavity and the annular cavity have depths in an axial direction; and the depth of the flat cavity is less than that of the annular cavity.
The bladeless fan has the characteristics of low air flow transmission loss, stable structure, attractive shape, and the like. Without blade fan Technical field. The utility model relates to a kind of fan. Especially, but be not in exclusive manner, the utility model relates to a kind of domestic fan, as the family expenses desk fan, for increasing air circulation and the Air Flow in indoor, office and other environment. Traditional domestic fan generally includes motor and is driven one group of blade or the impeller rotatablely move by motor.
This group blade is usually located in cage, and this cage allows air stream to pass, yet but stops human body to touch the blade of rotation. But in some cases, this kind fan also exists the danger that human body touches this group rotation blade.
This kind fan provides comparatively uniform air-flow and has improved the Security of using. But the nozzle of this kind fan easily is out of shape, the transmission loss of the interior air-flow of nozzle is larger.
The utility model aims to provide a kind of improved fan to overcome above-mentioned defective of the prior art. The purpose of this utility model is will provide-fan of the less and stabilized structure of the transmission loss of kind of air-flow; Another purpose of the present utility model is will provide a kind of can show the internal structure of nozzle and reduce the fan that light stops.
Advantageously, this kind do not need to expose fan blade without blade fan and just can produce air stream and form cooling effect; Because nozzle not only has toroidal cavity, but also have the pancake cavity that is communicated with this toroidal cavity, flow resistance and the flow loss of its air-flow in cavity significantly reduces; Consist of the chamber wall of pancake cavity and the chamber wall of looping cavity and be connected to each other or support, be conducive to improve the solidness of whole nozzle, make it be difficult for occuring deformation; In addition, the degree of depth of pancake cavity is conducive to make nozzle-integrated attractive in appearance less than the degree of depth of described toroidal cavity.
The degree of depth of described toroidal cavity is usually between 50mm to mm, preferably between 50mm to mm; The degree of depth of described pancake cavity is usually between 5mm to 80mm, preferably between 5mm to 50mm.
For the manufacturing efficient that improves nozzle and the stable degree of strengthening nozzle, it is whole, namely integrated that the chamber wall of described pancake cavity preferably becomes with section's chamber-separating wall of described toroidal cavity.
