Title: Far Infrared Ray Wooden Floor

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a floor structure, and more particularly to a far infrared ray wooden floor. 
     2. Description of Related Art 
     The far infrared ray (FIR) is a kind of light beam and electromagnetic wave for health purpose and has a penetrating and absorbing nature. Based on researches, the FIR can deeply penetrate and be in resonance with the human tissue, such that the cells in human body absorb the energy of FIR and are activated to increase the circulation among the cells and blood capillaries. The tissue might eliminate the unhealthy matters from the human body to provide a prophylactic effect. Therefore, FIR is broadly applied for daily use to provide medical care effects. 
     It is known that the FIR technology can be utilized on textiles for keeping warm and sterilization. However, there is no utilization which applies the FIR technology to the wooden articles, especially to the wooden floor. 
     To overcome the shortcomings, the present invention tends to provide a far infrared ray wooden floor to mitigate or obviate the aforementioned problems.
