Detailed description of the invention
Fig. 1 shows the outside of the housing 10 of ventilation unit, and the housing 10 of ventilation unit can be pacifiedBe contained on the roof of building. Pipeline passes in and out with conveying air in housing 10 and to downward-extensionThe inside of building.
Housing 10 is substantially square in top view, and each side of device 10 all has shutter dressPut 12. Blinds apparatus 12 is intended for the windward side at housing 10, air being received so that air entersEnter pipeline, and the Bas Discharged receiving via pipeline is arrived to relative leeward side. The present invention relates toBlinds apparatus 12, now more specifically describes blinds apparatus 12. The size energy of device 12Enough determined by particular case, but possible size range is included in hereinafter in described content.
Each blinds apparatus 12 all limits multiple passages 14, this passage in the corresponding side of housing 1014 can optionally carry out partly or integrally closing. In the outside of blinds apparatus 12,Each blinds apparatus 12 includes isolated multiple fixing venetian blind type second component 16,And in the inner side of blinds apparatus 12, each blinds apparatus 12 includes isolated multipleMovable venetian blind type first component 18.
In venetian blind type second component inner side, this venetian blind type second component has upright vertically protrudingEdge 20, this vertical flange 20 extends between 40mm and 70mm. Connecting plate 22 is from flange20 downwards and the horizontal range stretching out between 35mm and 60mm, connecting plate 22 withFurther interconnect to the vertical flange 24 of downward-extension, wherein, vertically flange 24 is at 25mmAnd extend between 50mm. The inner surface of flange 24 becomes profile to be with the exterior section of connecting plate 22Limit concave surface 26, concave surface 26 has the radius between 30mm and 50mm, to promote skyGas inwardly and downwards turns to by concave surface 26.
Movable venetian blind type first component 18 is and has recessed upper surface 28 and recessed following tableThe form of the profiled member of face 30 has slightly large recessed degree, upper surface 28 on upper surface 28With the radius of lower surface 30 respectively at scope and the 55mm to 65mm of 35mm to 45mmScope in. The outer rim place of contiguous first component 18 be provided with towards below slit 32, andAnd slit 32 is of a size of on the flange 20 of second component and coordinates slidably. Movable FirstPart 18 has between the height between 40mm and 70mm and 35mm and 60mmThe degree of depth.
Movable first component 18 is interconnected by bracing beam 34 in its corresponding end. Fig. 4Show the bracing beam 34 such with attached two of first component 18, although in Fig. 4 summaryFirst component 18 and second component 16 be shown, but first component 18 and second are not shownThe complete profile of part 16. Bracing beam 34 is all interconnected by cross bar 36, and horizontal stroke has been shown in Fig. 4In bar 36 one, cross bar 36 is with attached for the actuator means (not shown) activating.Described actuating can manually provide or be provided by electro-motor or actuator, and can carryFor its automatic operation.
In the time using with the state of opening completely as illustrated in fig. 2, by the air shown in arrow 38Will be by passage 14, passage 14 has the opening between 30mm and 70mm, and emptyGas be arranged essentially parallel to connecting plate 22 but upwards turn to run into venetian blind type first component 18 outsideSurface. Then, air inwardly and is downwards guided by concave surface 26. Along with air further move intoEnter, air is also guided downwards by the lower surface 30 on venetian blind type first component 18, same to space-timeGas also accelerates by the gap diminishing of being caused by upper recess surface 28.
The arrow 38 of right-hand side show air essentially horizontally enter ventilation unit 10 inPortion, the direction of the exterior section of this passage limiting from connecting plate 22 is different, 22 of connecting platesThe direction of the exterior section of the passage limiting is the degree of being inclined upwardly between 20 ° and 40 ° generally.
If for example needed partly in boisterous situation or closing passage 14 integrally,Venetian blind type first component 18 can move upward and make slit 32 motions leave vertical flange 20,And parts 18 can move to the position of closing completely as shown in Figure 3.
Thus, described ventilation unit, this ventilation unit provides the improved sky that enters its insideGas passage makes air turn to provide the efficiency of enhancing downwards in the time that air enters this device. Also retouchState and allow as required the blinds apparatus of closing partially or entirely.
Without departing from the scope of the invention, can carry out multiple remodeling. For example shutterDevice can have different profiles. Movable shutter parts can interconnect in a different manner mutuallyConnect and/or move. Movable shutter parts, fixing shutter parts can be by different wayBe bonded with each other.
Although pay close attention to as possible those of particular importance of being considered to of the present invention in aforesaid descriptionFeature, but should be appreciated that no matter whether it has been carried out emphasizing especially, applicant requires rightMentioned above and and/or any feature of granting patent illustrated in the accompanying drawings or featureCombination protect.
