DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1A, a ventilating roof in accordance with the invention comprises a roof structure 10 including a ventilating ridge roll 110 having a triangular longitudinal section, the ventilating ridge roll 110 having two vent holes 111 at two ends respectively, two base members 120 having a bent inner end, and a gap 100 formed between the base members 120; and two side panels 20 including a main panel 200 secured to the vent hole 111 and a drain hole 210 at a lower end, the drain hole 210 secured to an intermediate portion of the base member 120.

It is envisaged by the invention that an angle ∠ between the bent inner end of the side panel 120 and the main portion of the side panel 120 is between 120 and 180 degrees. Width of the ventilating ridge roll 110 is less that that of the roof structure 10. The vent hole 111 has an opening larger than an opening of the drain hole 210. Ventilation of a housing having a ventilating roof of the invention can be carried out by exiting hot air out of the housing via both a first path from the gap 100 and one vent hole 111 and a second path from the gap 100 and the other vent hole 111. The ventilation is carried out by natural convection without consuming power. The side panels 20 can prevent rain water from falling into the roof. Rain water may fall into the roof via the vent holes 110 and advantageously flow out of the roof via the drain holes 210 to completely drain. Thus, the invention is also capable of preventing rain water from entering a house.

Referring to FIG. 1B, another configuration of the first preferred embodiment of the invention is characterized by the ventilating ridge roll 110 is convex and the inner end of the base member 120 is not bent.

Referring to FIG. 2, a ventilating roof in accordance with a second preferred embodiment of the invention is shown and comprises two base members 30 including an inner end member 320, a gap 300 formed between the base members 30, two inclined side panels 310 mounted on the base members 30, a bent top support 311 at a joining portion of tops of the side panels 310, each side panel 310 having a vent hole 440 at a bottom end; and a ventilating ridge roll 40 having a triangular longitudinal section and including two inclined main panels 400 joined at a top, each main panel 400 having a vent hole 410 at a top end and a drain hole 420 at a bottom end, and an elongated cover 430 mounted on a top of the ventilating ridge roll 40.

It is envisaged by the invention that width of the side panels 310 is less that that of the base members 30. The vent hole 410 has an opening larger than an opening of the drain hole 420. Ventilation of a housing having a ventilating roof of the invention can be carried out by exiting hot air out of the housing via both a first path from the gap 300 and one vent hole 410, a second path from the gap 300 and the other vent hole 410, a third path from the gap 300, one vent hole 440, and one vent hole 410, and a fourth path from the gap 300, the other vent hole 440, and the other vent hole 410. The ventilation is carried out by natural convection without consuming power. The ventilating ridge roll 40 can prevent rain water from falling into the roof. Rain water may fall into the roof via the vent holes 410, flow down on the side panels 310 and advantageously flow out of the roof via the drain holes 420 to completely drain. Thus, the invention is also capable of preventing rain water from entering a house.

Referring to FIGS. 3, 4A and 4B, a ventilating roof in accordance with a third preferred embodiment of the invention is shown and comprises two base members 50 including a gap 500 formed between the base members 50; two sets of two engaged ventilation pipes 70 having a plurality of vent holes 700, each set of the ventilation pipes 70 mounted on an inner end of the base member 50, a ventilating ridge roll 60 mounted on the sets of the ventilation pipes 70, and two exits 80 each formed between an end of the ventilating ridge roll 60 and one base member 50 by the ventilation pipes 70.

It is envisaged by the invention that width of the ventilating ridge roll 60 is greater than that of the gap 500. Ventilation of a housing having a ventilating roof of the invention can be carried out by exiting hot air out of the housing via both a first path from the gap 500 and one exit 80 via the vent holes 700 of one set of the ventilation pipes 70 and a second path from the gap 500 and the other exit 80 via the vent holes 700 of the other set of the ventilation pipes 70. The ventilation is carried out by natural convection without consuming power. The ventilation pipes 70 can prevent rain water from falling into the roof. Thus, the invention is also capable of preventing rain water from entering a house.

Referring to FIG. 5, a ventilating roof in accordance with a fourth preferred embodiment of the invention is shown and comprises a ventilating ridge roll 60 having one end formed with a portion of the base member 50, a gap 500 through the base member 50, three engaged ventilation pipes 70 mounted on the base member 50, and an exit 80 formed between an end of the ventilating ridge roll 60 and the base member 50 by the ventilation pipes 70.

While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
