Description

BACKGROUND OF THE INVENTION

The present invention relates generally to a solar ventilator and a ventilating system with the solar ventilator, and more particularly to an innovative one which permits to convert the available solar energy into electric energy required for the ventilator in the daytime, and also store the converted electric energy into the energy storage unit to provide power required for the ventilator in the nighttime; the solar ventilator can be applied to the external surface or interlayer of the building roof so as to form the building's ventilating system.

With the growing awareness of environmental protection and energy saving, a high priority of technological development must be placed on environmental protection and energy conservation to meet the energy-depleting challenges in the future. Thus, the key concern of research and development is to develop new energy sources or convert and utilize the energy sources in the nature or recycle the energy sources. Given the highest availability of solar energy in the nature, the technology of converting solar energy into electric energy is becoming more mature, and also commonly used to provide electric source for the people's everyday life. To save power of the factories or workshops with a bigger power consumption, several ventilators are generally arranged on the roofs of such industrial buildings. However, such spherical ventilators are protruded from the surface of roof, and rotated under the drive of air convection to pump out the indoor hot air; but, the protruding of spherical ventilators from the roof surface is not aesthetically pleasing, and the natural convection method for driving the rotation of ventilator blade and pumping out hot air cannot bring about good result. For this reason, power supply is adopted to drive the ventilator for forced air convection and pumping, leading to increase of power consumption and operating cost; some improvements are thus made to install a solar panel, which converts the absorbed solar energy into electric energy required for the ventilator, thus reducing greatly the power consumption in the daytime. However, many industrial workshops are running around the clock, so the ventilating system must be operated day and night, and indoor power supply shall be provided for the ventilator in the nighttime to resolve the problem in this regard.

Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.

Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
