Door panel

Abstract

The aperture area efficiency of a door panel with a double-panel structure having an outer panel and an inner panel is increased, while turbulent flow of air through ventilation holes is reduced. The outer panel 21 is provided with a plurality of honeycomb ventilation hole sections 26, each of which comprises a plurality of hexagonal ventilation holes 25 that are formed in the outer panel 21 so as to be arranged in a honeycomb pattern, with each side of each ventilation hole 25 being adjacent to a side of another ventilation hole 25 with a connecting portion 25 a therebetween. The inner panel 23 is provided with ventilation openings 30, each of which is slightly larger than each respective honeycomb ventilation hole section 26 of the outer panel 21.

1 . A door panel comprising:
 an outer panel; and   an inner panel formed having an uneven surface with a recessed portion and a raised portion, the recessed portion affixed to the inner surface of the outer panel, wherein:   the outer panel with includes a honeycomb-shaped ventilation hole cluster formed of a plurality of hexagonal ventilation holes that are arranged in a honeycomb pattern, with each side of each respective ventilation hole being adjacent to a side of another ventilation hole with a connecting portion therebetween; and   the inner panel includes a ventilation opening that is formed in the recessed portion, at a locations corresponding to the honeycomb-shaped ventilation hole cluster of the outer panel.   
     
     
         2 . A door panel as claimed in  claim 1 , wherein:
 the ventilation opening of the inner panel is larger than the honeycomb-shaped ventilation hole cluster of the outer panel.
