Description

FIELD OF THE INVENTION

The present invention relates to a ventilation roof which contains a zigzag channel configured to flow airs effectively.

BACKGROUND OF THE INVENTION

Referring to FIG. 1, a conventional ventilation roof contains two opposite frames 9 (one of the two opposite frames is shown) and mate with a covering plate 910 so that air flows outside and inside a building, wherein a zigzag channel is defined among each of the two opposite frames 9 and multiple stop members 90.

Each frame 9 includes a top sheet 91, a bottom sheet 92, an internal fence 93, and a hollow portion 94 surrounded by the top sheet 91, the bottom sheet 92, and the internal sheet 93. The internal sheet 93 has an air inlet 931 extending from a horizontal direction X, and the bottom sheet 92 has an air vent 921 defined along the horizontal direction X, wherein the air inlet 931 is higher than the air vent 921, and the air vent 921 and the air inlet 931 communicate with the hollow portion 94. The internal fence 93 has multiple recesses 932 configured to retain with each of the multiple stop plates 90, and the multiple stop members 90 are crisscross arranged downward so that the zigzag channel forms in the hollow portion 94, and hot air flow discharges out of the air inlet 931 along the zigzag channel.

Although the zigzag channel is defined by the air inlet 931, the air vent 921, and the multiple stop members 90, a back pressure of a wind resistance produces because the air vent 921 is defined along the horizontal direction X, thus lowering air ventilation as discharging the hot air flow.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary aspect of the present invention is to provide a ventilation roof which discharges hot air flow effectively and reduces a back pressure.

To obtain above-mentioned aspects, a ventilation roof provided by the present invention comprises: at least one frame and multiple stop members.

The at least one frame includes at least one top sheet, at least one bottom sheet, at least one internal fence, and at least one hollow portion surrounded by the at least one top sheet, the at least one bottom sheet, and the at least one internal fence. The at least one top sheet has at least one air vent defined along a vertical direction, the at least one internal fence has at least one air inlet extending from a horizontal direction and communicating with the at least one air vent and the at least one hollow portion, and each of the at least one internal fence has multiple recesses.

The multiple stop members are retained in the multiple recesses and are crisscross accommodated in the at least one hollow portion so that at least one zigzag channel forms in the at least one hollow portion.

The at least one air vent of the present invention is defined along the vertical direction, so the hot air flow discharges out of the building easily by using a pressure drop of the exterior wind, when guiding the hot air flow in the building.

The hot air flow flows upward along the zigzag channel and discharges out of the air vent in the vertical direction so as to overcome the wind resistance. Furthermore, the rainwaters do not flow into the building from the air vent by way of the at least one stop member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 2 and 3, a ventilation roof 100 according to a preferred embodiment of the present invention is mounted on an opening 110 of a corrugated roofing sheet 100 of a building and mates with a covering plate 200 (such as made of tempered glass) so as to obtain bright lights and heat dissipation. In this embodiment, the ventilation roof 100 comprises two opposite frames 1 symmetrically arranged and two stop members 2 accommodated in each of the two opposite frames 1.

Each of the two opposite frames 1 includes a hollow body, a cross section of which is in a rectangle shape, a top sheet 11, a bottom sheet 12, an internal fence 13, and a hollow portion 14 surrounded by the top sheet 11, the bottom sheet 12, and the internal fence 13.

The top sheet 11 has an air vent 111 defined along a vertical direction Y and communicating with the hollow portion 14, and the air vent 111 has a mesh layer formed on a top thereof.

The bottom sheet 12 has a water outlet 121 in communication with the hollow portion 14.

The internal fence 13 of each frame 1 has an air inlet 131 extending on a side thereof from a horizontal direction X, and the internal fence 13 has multiple recesses 132 defined thereon, wherein the air vent 111 and the air inlet 131 communicate with the hollow portion 14, and the recess 132 is configured to retain each of the two stop members 2.

Each stop member 2 is retained ion the recess 132, and the two stop members are crisscross accommodated in the hollow portion 14 so that a zigzag channel (denoted by an arrow in FIG. 3) forms in the hollow portion 14.

Each stop member 2 includes a first segment 21 retained in the recess 132, a second segment 22 opposite to the first segment 21, and multiple drainage holes 23 defined between the first segment 21 and the second segment 22. In this embodiment, the two stop members 2 are obliquely and oppositely fixed in the hollow portion 14 and tilt upward along the horizontal direction X, wherein a tilted angle of each stop member 2 is less than 45 degrees. A distal portion 221 of the second segment 22 extends upward along the vertical direction Y, and two second segments 22 of the two stop members 2 are crisscross arranged so as to postpone airs and rainwaters to flow into the building from the air vent 111 and to avoid the rainwaters rushing back to the building from the hollow portion 14 via the air inlet 131. Each stop member 2 is obliquely fixed in the hollow portion 14 so as to avoid the rainwaters gathering in the building by way of the multiple drainage holes 23.

In this embodiment, one of the two stop members 2 proximate to the air inlet 131 is located on the side of the internal fence 13 on which the air inlet 131 is defined, the one stop member 2 is located above the air inlet 131, and the zigzag channel is a flowing path in which the airs flow along the air inlet 131, the two stop members 2, and the air vent 111.

In assembly, hot air flow in the building flows upward via the opening 110 and enters into the zigzag channel via the air inlet 131, thereafter the hot air flow discharges out of the air vent 111 along the zigzag channel. The air vent 111 is defined along the vertical direction Y, so a low pressure portion of exterior wind produces in the air vent 111 and does not stop the air vent 111 when the wind flows, thus dissipating the hot air flow out of the building.

The conventional ventilation roof contains the channel downward extending to the air vent so that the hot air flow discharges upward, thus causing wind resistance to reduce air ventilation.

The air vent 111 of the present invention is defined along the vertical direction Y, so the hot air flow discharges out of the building easily by using a pressure drop of the exterior wind, when guiding the hot air flow in the building.

The hot air flow flows upward along the zigzag channel and discharges out of the air vent in the vertical direction so as to overcome the wind resistance. Furthermore, the rainwaters do not flow into the building from the air vent 111 by way of the two stop members 2.

While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
