VENTILATION DEVICE
A ventilation device includes a frame unit, a vent unit, and an air circulating unit. The frame unit cooperates with a building to form an air chamber having a vent opening and an outlet. The vent unit cooperates with the vent opening and the air chamber to define a first venting pathway, and has a vent slot facing the air chamber. A ratio between an area of the vent slot to an area of the outlet is less than 0.33. The air circulating unit includes a window movable between a closed position to block the outlet, and an open position where the outlet is unblocked and cooperates with the vent opening and the air chamber to form a second venting pathway.
This application claims priority of Taiwanese Patent Application No. 107105564, filed on Feb. 14, 2018.
FIELDThe disclosure relates to a ventilation device, and more particularly to a ventilation device for a building.
BACKGROUNDReferring to
Each of the hollow frames 11 ventilates hot air out of the building through the first venting pathways (I), and prevents rain from splashing into the building therethrough. However, during emergencies such as fire, when a large amount of smoke is required to be exhausted from the building, the rate in which the ventilating device 100 is capable to exhaust through the first venting pathways (I) is rather limited.
SUMMARYTherefore, an object of the disclosure is to provide a ventilation device that can alleviate the drawback of the prior art.
According to the disclosure, the ventilation device includes a frame unit, at least one vent unit, and an air circulating unit. The frame unit is adapted to be mounted onto a surface of a building and includes at least one guiding bar. The frame unit is adapted to cooperate with the building to form an air chamber that has a vent opening and an outlet, which are respectively adjacent to interior and exterior of the building.
The at least one vent unit is disposed on the at least one guiding bar, and has a vent slot set that is adjacent to and in fluid communication with the air chamber, a vent hole set that is adapted to be adjacent to and in fluid communication with the exterior of the building and that is in fluid communication with the vent slot set, and a vent chamber that is formed in the at least one guiding bar and that is in fluid communication with the vent slot set and the vent hole set. The vent chamber cooperates with the vent opening, the air chamber, the vent slot set and the vent hole set to form a first venting pathway.
The vent slot set has at least one vent slot. Each of the outlet of the air chamber and the at least one vent slot has an opening that faces the air chamber. The ratio between an area of the opening of the at least one vent slot to an area of the opening of the outlet is less than 0.33.
The air circulating unit includes a window that is mounted on the frame unit, and that is movable relative to the frame unit between a closed position, where the outlet is blocked by the window such that the interior of the building fluidly communicates with the exterior of the building through the first venting pathway, and an open position, where the outlet is unblocked such that the interior and exterior of the building fluidly communicate through the first venting pathway and a second venting pathway, which is defined cooperatively by the vent opening, the air chamber and the outlet.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment with reference to the accompanying drawings, of which:
Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.

The frame unit 2 is adapted to be disposed above the roof opening 911 of the roof 91, to be fixedly mounted on the roof 91, and to cooperate with the roof 91 to form an air chamber 200 that has a vent opening 201 and an outlet 202, which are respectively adjacent to interior and exterior of the building 9. In this embodiment, the frame unit 2 includes two spaced-apart mounting bars 21 that are adapted to be connected to the roof 91 and that extend in a first direction (X), two guiding bars 22, and two supporting members 23 spaced apart from each other in the first direction (X). Each of the guiding bars 22 extends in the first direction (X) and is connected to a top end of a respective one of the mounting bars 21. Each of the supporting members 23 includes two parallel rod segments extending in a second direction (Y) transverse to the first direction (X) and interconnecting the guiding bars 22. In this embodiment, the first direction (X) is perpendicular to the second direction (Y). In this embodiment, each of the mounting bars 21 and the respective one of the guiding bars 22 are assembled after initial manufacturing, but may be molded as a single piece in other configurations of the embodiment. In this embodiment, the rod segments of the supporting members 23 are configured as hollow and metallic bars. However, the supporting members 23 may be made of plates to enclose two opposite ends of the air chamber 200 in the first direction (X) for improving airtightness of the air chamber 200.
Each of the mounting bars 21 has a fixed mounting portion 211 that protrudes toward the air chamber 200 to compliment shape of the roof 91, and that is fixedly mounted onto the roof 91 in a position adjacent to the roof opening 911. Each of the guiding bars 22 has an inner side plate 220 that is adjacent to the air chamber 200, an outer side plate 221 that is spaced apart from the inner side plate 220, a top plate 222 that is proximate to the outlet 202 and that interconnects top ends of the inner and outer side plates 220, 221, and a bottom plate 223 that interconnects bottom ends of the inner and outer side plates 220, 221. The inner side plate 220, the outer side plate 221, the top plate 222 and the bottom plate 223 extend in the first direction (X). In this embodiment, the top plate 222 of each of the guiding bars 22 is formed with an indented section 224 that extends in the first direction (X) and that is connected to the inner side plate 220.

The air circulating unit 5 includes a window 51 that is mounted to the frame unit 2 and that is movable relative to the frame unit 2, a driving member 52 that drives movement of the window 51, and a control 53 that is electrically connected to the driving member 52 for operating the driving member 52.
In this embodiment, the connecting seat 4 is mounted between the frame unit 2 and the window 51. The window 51 has a window frame 511 that is formed with a window opening 514 and that has an end pivotally mounted to the base wall 411 of the connecting seat 4 by two hinges 513, and a window pane 512 that is embedded in the window frame 511 and that blocks the window opening 514 from being fluidly communicated with the exterior of the building 9. The window frame 511 has an abutment portion 515 that extends inwardly, and the window pane 512 is placed on and abuts against the abutment portion 515.
In this embodiment, the inner surrounding wall 412 of the connecting seat 4 has a distal portion surrounded by the window frame 511 (see
In this embodiment, the driving member 52 of the air circulating unit 5 is air-pressured, is connected between the frame unit 2 and the window 51, and has a cylinder body 521 that is connected pivotally to the frame unit 2, and a piston rod 522 that is inserted telescopically into the cylinder body 521 and that is connected pivotally to the window 51.

With the abovementioned description considered, the benefit of the disclosure may be summarized as the following:
1. The ratio between the area of the opening of the outlet 202 to the sum of the area of the opening of the vent slots 311 is greater than 3, such that the air flow rate of the second venting pathway (F2) is much greater than that of the first venting pathway (F1). Given how straightforward the second venting pathway (F2) is, it is optimal for clearing smoke out of the building 9 quickly.
2. The window pane 512 offers natural lighting into the building, reducing the use of mechanical lighting and heat generated therefrom.
3. As shown in
4. During a fire, the window 51 may be changed from the closed position to the open position by using the driving member 52 and the control 53 to quickly open up the second venting pathway (F2) for smoke clearing.
