Samsung patents vacuum cleaner fan design that changes air flow path
Samsung has been granted a patent for a vacuum cleaner design that uses a specific fan and motor setup to move air through the device. The system uses a spinning impeller and two types of guides, called diffusers, to direct air from the fan to a filter and then out of the machine.
In the filing’s own words
A cleaner including a body including a body exhaust vent; a filter installable inside the body; and a fan motor device including a rotatable impeller to generate a suction force inside the body, a motor to rotate the impeller, and a diffuser device including a radiating diffuser extending in a radial direction from a rotational axis of the impeller, and an axial diffuser extending from the radiating diffuser. The fan motor device is configured so that, with the filter installed inside the body, rotation of the impeller by the power provided by the motor causes air to pass through the fan motor device and be discharged from the impeller, and then guided by the radiating diffuser in the radial direction from the rotational axis of the impeller, and then guided by the axial diffuser to the filter to be filtered, and then discharged through the body exhaust vent.
What exactly they claim (claim 1)
1. A cleaner comprising: a body including a body exhaust vent; a filter installable inside the body; and a fan motor device including: an impeller configured to be rotatable to generate a suction force inside the body, a motor configured to provide power to rotate the impeller, and a diffuser device arranged about the impeller and including: a radiating diffuser extending in a radial direction from a rotational axis of the impeller so as to surround the impeller, and an axial diffuser extending integrally from the radiating diffuser so as to surround the impeller, wherein the fan motor device is configured so that, with the filter installed inside the body, rotation of the impeller by the power provided by the motor causes air to pass through the fan motor device about the motor before reaching the impeller, and then be discharged from the impeller directly into the diffuser device, and then guided by the radiating diffuser in the radial direction from the rotational axis of the impeller, and then guided by the axial diffuser to the filter to be filtered, and then discharged through the body exhaust vent, and the diffuser device is configured to discharge the air in an opposite direction to which the air enters the impeller.
