OMIT is obviously not comparable in terms of power to a traditional vacuum cleaner, but it is quiet and useful. I wish I could say the same about all the people I know. Ah! I almost forgot. It does not require electricity: an object that brings some comfort even off-grid.
The designer thought about OMIT while living with roommates because he couldn't use the noisy vacuum cleaner on weekdays. “I realized that around 70% of users can only use the vacuum cleaner on weekends, due to noise and cable problems. On balance it was a "rediscovery": in the nineteenth century there were already hand vacuum cleaners. Without electricity they can be quieter "Also, I found that before electric vacuum cleaners, hand vacuum cleaners were used in the XNUMXth century. I thought vacuum cleaners could be quieter and more manageable by omitting electricity," says the designer Hiroyuki Morita.
How OMIT works
This compact vacuum cleaner works by turning the knob several times. The force is transmitted to the suction fan which increases the number of revolutions with a special mechanism. OMIT requires 5 turns of the knob to operate 10 seconds. To achieve sufficient suction power, the mechanism works with several key elements. The first it is the gear that increases the number of revolutions from 1 to 600. To create the necessary force, The second one element is a torsion spring which makes OMIT work longer. The third The key element is the needle bearing which rotates only in one direction and constantly transmits the force of the torsion spring to the gear. The collected dust goes into a washable container that is easy to clean and maintain.
OMIT uses the principle of the free wheel in its mechanism where pulling a rope makes a wheel spin constantly. However, the action of pulling the rope is physically difficult to do if you want to maintain the power of the vacuum cleaner long enough. The key was to figure out how to control the direction of the air.
To make the rotation easier and more stable, I added a torque spring and a planetary gear. The combination translates small actions into a large number of spins. When I found the principle, I designed the optimal arrangement of the components.Hiroyuki Morita
The "electric" vacuum cleaner without electricity: a progenitor?
The absence of electricity challenges traditional handheld vacuum cleaners. OMIT could be a new type of cleaning products: more powerful than the broom and with fewer resources than the vacuum cleaner. It is minimal but powerful and solves the problem of noise plus that of electricity consumption. OMIT is ideal for cleaning small spaces such as kitchens and desks, as well as car interiors, with the plus of energy saving.
