Patent number 8772959 is assigned to Lee;
The following quote was obtained by the news editors from the background information supplied by the inventors: "The subject invention entails a wind-propelled vertical turbine device that drives a power generator and a ventilator, or any heat dissipation device.
"The conventional roof ventilator is a kind of miniature windmill. When wind blows onto the blades the blades are rotated to exhaust hot air to outdoors. The ventilator typically does not incorporate the function of power generation. Even if the conventional ventilator was to be equipped with a generator, the typical ventilator blades have relatively small wind-catching area that the wind-powered torsion can hardly feed the power generator. Therefore, it is difficult for the conventional ventilator to provide additional power-generation function."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "It is the objectives of the subject invention to design a ventilator that will provide both power generation and ventilation through utilizing the most abundant and renewable wind energy.
"To achieve the above objectives, the subject invention incorporates three hardware components, namely, the vertical, multiple-blade wind turbine, a ventilator, and a power generator. All three components are inter-connected as an integral assembly that can provide ventilation function while generating electrical power.
"The purposes of the subject invention can be best achieved by installing the subject invention in the region with abundant wind flow.
"Through catching the wind energy the wind turbines will rotate and a significant torsion is created to concurrently drive the power generator and cause the ventilation blades to rotate to create outward airflow.
"The wind turbine component is a vertical, multiple-blade assembly designed to effectively catch wind energy. The size of the blades are enlarged and properly angled to maximize the catching of wind volume.
"The power generator assembly incorporates a coil winding on top, a shaft, and a bottom tray. The coil winding interacts with the magnet assembly on top of the ventilator housing for generating power.
"The ventilator consists of an upper disc-like magnet assembly circumferentially connected with multiple vertical ventilation blades and a lower rotary tray rotatably fitted on the shaft of the power generator by means of a bearing. The upper disc-like magnet assembly, the lower rotary tray and the vertical ventilation blades are assembled to form a cylindrical housing. The shaft protrudes upwardly from the center of the disc-like magnet assembly to be rotatably connected with the wind turbine, and driven by such wind turbine.
"In order to increase hot air exhaustion efficiency there are multiple circulation acceleration blades placed on the rotary tray of the ventilator to help speed up exhausting/ventilating process, whereby the hot air can be quickly exhausted through the turning of ventilating blades.
"The subject invention can be further explained through the following descriptions and accompanying drawings, wherein:
