How The Dyson Bladeless Fan Works
A bladeless fan has no external blade. Interesting right? You might be wondering how a bladeless fan circulates air in a room. Seeing this wonderful piece of technology would only leave you dazzled because its working principles cannot be comprehended from the characteristics of this fan.
The bladeless fan is a modern technology piece, quite different from the regular or traditional fans with blades. It is sometimes referred to as an air multiplier, blowing air from a ring having no blades. Wonderful, right?
With the bladeless fans, there are two models available. The Dyson and Panasonic model. The Dyson model was created by James Dyson in the year 2009, generating airflow of about 55mp. The Panasonic model became available in 2015 when the Panasonic company announced it.
Dyson fans are quiet and easy to clean. They are very safe to use in a room full of children or animals, it is bladeless and you don’t have to worry about their safety. It is built with an ultra-modern design that makes it easy to be placed in any area of the room irrespective of space.
This article would be focusing on the Dyson model. Getting you acquainted with the functions. Typical application procedures of how it actually works using the Dyson AM07 as a model example.
The mechanics of the Dyson bladeless fan.
Seeing the Dyson AM07, you’d think “wow that’s cool” then the next thought that comes to mind is “how does it work. “
Calling the Dyson AM07 fan bladeless was misleading. However, it seems it has kept you curious. Yes, there’s a twist to that.
The blades or vanes are creatively hidden within its futuristic design. A close inspection of the Dyson AM07, you’d find them inside the pedestal stand. It is used to draw or stir up about 5.28 gallons of air per second, exactly the same amount a vacuum cleaner draws in.
Within the pedestal stand, close to the blades are brushless electric motors perfectly fit in the pedestal stand. With this the air multiplier rotates the blades which are asymmetrically-aligned. This motor boosts up the fast flowing air.
Another function the motor does is to drive the generated air into the ring portion of the fan.
The air is channeled to the ring portion through a curved path, it passes through a 16mm silts found around the frame of the fan. These silts are position at angle of 16 degrees. Now, you might think that this would increase airflow, or making it to blow in a circular or cylindrical manner. But that’s not the case.
But how does the fan multiply air? now that’s physics related.
There are two laws affecting the operations of the Dyson AM07 or any bladeless fan. These are the physical laws of inducement and entrainment which are concerned with fluid dynamics.
During the flow of air through the silts out to the ring portion. There is a low pressure region at the back of the fan. This creates a gradient allowing air to be drawn in through the back of the fan. This is known as the inducement process.
Entrainment process has to do with the air surrounding the edges of the fan which begins to flows in the direction of the breeze. It is noted that rough these processes; inducement and entrainment, that the air multiplier’s airflow increases to about 15 times the amount generated from the internal blades of the motor in the pedestal stand.
Giving it the alternate name of an air multiplier.
This creates a quiet, even, constant flow of cool breeze making the Dyson AM07 a good choice for a home appliance.
