Description

Horizontal louver smoke exhausting window

Technical Field

The utility model relates to a ventilation equipment field specifically indicates a horizontal tripe smoke exhaust window.

Background

Blinds are a style of window, originating in china. The shutter can be used as a decoration, can play a role in ventilation and light transmission at the same time, and is often used in modern buildings. Traditional shutters are all designed vertically, and are not suitable for large-scale plants, workshops or warehouses. In order to solve the above problems, the chinese utility model patent with application number 201110213427.6 discloses a parallel air duct type natural ventilator, which specifically comprises a framework, at least two groups of rain-proof boards, a drainage channel arranged below the lower end edge of the lowest group of rain-proof boards, and the like; however, after long-term tests, the parallel air duct type natural ventilator disclosed in the patent mainly has the following problems; the parallel air duct type natural ventilator is only provided with the drainage grooves below the lower end edges of the lowermost group of the rain-proof plates, and the water grooves cannot be widened in order to reduce the airflow blocking effect of the parallel air duct type natural ventilator; if the drainage groove is widened to meet the drainage requirement, the widened drainage groove can obviously block airflow, so that the effective ventilation area of the ventilator is sharply reduced, and the ventilation requirement cannot be met; if the depth of the drainage groove is increased deeply, the attractiveness of the ventilator is affected, the bearing performance of the framework of the ventilator is reduced, the thickness of the framework needs to be greatly increased in order to improve the bearing performance, the material cost is increased, and other engineering problems which are difficult to process are caused in installation. In addition to the above problems, the parallel air passage type natural ventilator has some other problems such as:

(1) the effective ventilation area of the ventilator means the minimum area through which the airflow passes when passing through the ventilator; the effective ventilation area ratio refers to the ratio of the effective ventilation area of the ventilator to the area of the ventilator (or the area of the roof opening). Although the specification of the patent application No. 201110213427.6 discloses "the effective ventilation area is greater than 80% of the area of the roof opening", no other information is disclosed about greater than 80%. According to the information of the attached drawings of the published specification, the horizontal distance of air in a ventilation air channel between two adjacent rain-proof plates is large and is larger than 80%, if the horizontal distance of the air channel of the upper two layers neglects the influence of the thickness of the rain-proof plates, the horizontal distance is 100%, the rain-proof plate of the lowest layer is calculated according to the horizontal distance, the position which can directly block the air flow and is only the width of the bottom surface of the water tank can be directly blocked, and if the horizontal distance of the ventilation air channel capable of carrying out air circulation is taken as the effective ventilation width, the effective ventilation area of the patent can be larger than 80%; however, when the effective ventilation area of the ventilation air duct is actually calculated, the length of the air duct is multiplied by the narrowest width between the air ducts, namely, the minimum distance (namely, the vertical distance) capable of ventilating; in this patent, its water drainage tank sets up the below at the lower extreme border of a set of flashing board in the bottom, and its water drainage tank's the position of setting can block the air current, reduces the effective draught area in this ventilation wind channel for the vertical distance who is used for the ventilation between the ventilation wind channel diminishes, and then has reduced the effective draught area of whole ventilator. According to the calculation method of the effective ventilation area, the effective ventilation area ratio of the patent publication is between 39% and 41% in the attached figures 1 and 5; fig. 3, the effective ventilation area ratio is between 34% and 37%. In the information disclosed in this patent, there is no technical solution that can achieve an effective ventilation area ratio of 80% and at the same time achieve a good waterproof effect. In practical use, the market can obtain a technical scheme with a large effective ventilation area ratio. The information disclosed in this patent teaches that ventilators having an effective ventilation area ratio of 30% to 40% to that commonly found on the market do not have a significant ventilation advantage.

(2) This wind channel formula natural ventilator parallels when using, if the rainwater directly hits when the front of two layers of flashing, the rainwater can spatter and form the water droplet at the back of second layer flashing, this water droplet adsorbs the back at second layer flashing to can directly fall in optional position (relevant with rainfall, wind speed, factors such as wind-force size) when falling along the flashing incline direction, because third layer flashing and the adjacent basin of third layer do not have the handing-over, this water droplet can directly drip to indoor through the space between third layer flashing and the adjacent basin for its rain proofness can not reach the requirement.

(3) When rainwater directly hits on second floor flashing board, the rain that spatters that produces under the effect of wind, can directly get into indoorly through the space between third layer flashing board and the adjacent basin for its rain proofness can not reach the requirement.

(4) The water on the front face of the second layer of rain-proof plate flows downwards along the inclined direction, and fine splashing rain can be generated and splashed indoors when the water is dripped on the front face of the third layer of rain-proof plate, so that the rain-proof performance of the water-proof plate cannot meet the requirement.

(5) When the rain-proof umbrella is used, water drops can be generated on the framework, and the water drops can drop into the room downwards along the framework, so that the rain-proof performance of the rain-proof umbrella cannot meet the requirement.

(6) The weight of the whole parallel air duct type natural ventilator is supported by the framework, and the framework is installed on the base, so that the number of the bases is increased, the material cost is increased, and the installation difficulty of the ventilator is improved.

Because the parallel air duct type natural ventilator has the problems, the ventilator cannot be popularized.

In addition, utility model patent application No. 201520394299.3 discloses a rain-proof ventilation shutter of level, as ventilation shutter, the rain-proof performance of air permeability is key function, this patent does not have the information of disclosing effective draught area equally, the rain-proof performance of this patent has great defect equally, when strong wind, heavy rain, rainstorm, the wind direction is random, the mounted mode of shutter must satisfy the service condition, can not select, rainwater gets into inside the shutter along with the wind direction like this, directly hit when the well lower part of shutter plate concave part, must take place to spatter rain, spatter rain and can directly get into inside the room, also can spatter the front at adjacent shutter plate, and collect and flow into in the room, therefore the defect of this patent is obvious.

Therefore, how to solve the above problems is a current urgent task.

Specifically, this rain-proof mechanism includes at least two-layer shutter plate 2 that from top to bottom sets gradually, sets up drainage tank 3 at each layer of shutter plate 2 lower extreme respectively, as shown in fig. 1. In this embodiment, each rain-proof mechanism includes 3 louvres 2 to 3 louvres 2 arrange from top to bottom in proper order. Any point on the horizontal plane where the upper end edge of the uppermost louver blade 2 is located is used for downwards making rays of any angle, and the rays are all shot on the louver blade 2 or the drainage groove 3 of any rainproof mechanism, so that rainwater cannot directly penetrate through the louver blade 2 and enter the indoor space in the rainy day.

The shape homogeneous phase of shutter plate 2 and water drainage tank 3 in two adjacent rain-proof mechanisms, and in two adjacent rain-proof mechanisms between the shutter plate 2 of the same layer be parallel to each other, in two adjacent rain-proof mechanisms also can be parallel to each other between the water drainage tank 3 of the same layer. That is, the louver blades on the uppermost layer of the two adjacent rainproof mechanisms and the drainage grooves 3 are identical in shape and parallel to each other, the louver blades on the middle layer and the drainage grooves 3 are identical in shape and parallel to each other, and the louver blades on the lowermost layer and the drainage grooves 3 are identical in shape and parallel to each other.

Furthermore, at least two adjacent layers of upper and lower louver blades 2 in the same rainproof mechanism have opposite inclination directions or different inclination angles.

As an alternative, the slats 2 of one of the layers of the same flashing mechanism are perpendicular to the horizontal plane and the slats 2 of the remaining layers form an acute angle with the horizontal plane, as shown in fig. 12.

As a preferable scheme, as shown in fig. 23, at least three layers of louvres 2 are contained in one rain-proof mechanism, and in the same rain-proof mechanism, the upper ends of the louvres 2 are connected with the drainage grooves 3 on the upper layer, so that the rain-proof mechanism forms an integral structure; specifically, the upper end of the louver blade 2 is connected with the left side or the right side or the middle part of the drainage groove 3 on the upper layer, and the connection position can be set according to the actual situation; in this solution a rain mechanism is provided with three layers of louvres 2.

As another preferable scheme, as shown in fig. 1, 11 and 16, the louver 2 forms an acute angle α with the horizontal plane, and the lower end of the louver 2 in the same layer is connected with the upper end of a side wall of the drainage channel 3 close to the louver 2, or is positioned above the side wall of the drainage channel 3 close to the louver 2, or extends into the drainage channel 3, while the upper end of the side wall of the drainage channel 3 far from the louver 2 is positioned on a plane which has a vertical distance X from the louver 2 and is parallel to the louver 2, as shown in fig. 16; or the upper end of the side wall of the drainage channel 3 far from the louver blade 2 is positioned below the plane which has the vertical distance X with the louver blade 2 and is parallel to the louver blade 2, as shown in FIG. 17; in the embodiment, alpha is more than or equal to 30 degrees and less than or equal to 80 degrees; and X is N sin alpha-N0.45, wherein N is the horizontal distance between two adjacent louvres and can be set according to the length of the smoke exhaust window.

As another preferred mode, as shown in fig. 1, the louver blade 2 is provided with a rib 4, and/or one or more bent portions 6 are formed at the upper end portion of the louver blade 2, so that the strength of the louver blade 2 can be improved.

In the structure, a ventilation air duct is formed between two louvres 2 on the same layer and between two drainage grooves 3 on the same layer of two adjacent rainproof mechanisms; when the minimum ventilation area of the ventilation air duct is calculated, the width of the ventilation air duct is actually calculated according to the minimum value of the vertical distance L from the upper end of the side wall of one side, far away from the louver blade 2, of the drainage groove 3 to the louver blade 2 adjacent to the drainage groove 3, the vertical distance M between two adjacent drainage grooves 3, the vertical distance H between two adjacent louver blades 2 and the shortest vertical distance K from the end point of the bending part to the adjacent louver blade, the width of the ventilation air duct is multiplied by the length of the ventilation air duct to be equal to the effective ventilation area of the ventilation air duct, and the sum of the effective ventilation areas of all the ventilation air ducts is the effective ventilation area of the louver smoke exhaust window. As shown in FIGS. 18 to 21, M ≧ L, H ≧ L, and K ≧ L are provided in the present embodiment, and the specific value of M, H, L, K can be set according to the actual situation, so in the present embodiment, the effective ventilation area ratio e of the ventilation duct is calculated by the vertical distance L from the upper end of the side wall of the drainage channel 3 on the side far from the louver 2 to the louver 2 adjacent to the drainage channel 3.

Further, as can be seen from the above formula, when the value N is fixed, the larger the angle α is, the larger the vertical distance H between the two louvers is, the larger the vertical distance X is, N X sin α -N0.45 is, and when M is equal to or greater than L, H is equal to or greater than L, K is equal to or greater than L, and the upper end of the side wall of the drain channel 3 on the side away from the louver 2 is located below the plane parallel to the louver 2 at the vertical distance X from the louver 2, the larger the effective ventilation area ratio e that can be achieved by the ventilation duct is.

When M is larger than or equal to L, H is larger than or equal to L, K is larger than or equal to L, the effective ventilation area (minimum ventilation area) of the ventilation air duct is equal to the vertical distance L multiplied by the length of the ventilation air duct from the upper end of the side wall of one side, far away from the louver blades, of the drainage groove to the louver blades adjacent to the drainage groove, the area of the ventilation air duct is equal to the horizontal distance N multiplied by the length of the ventilation air duct between two adjacent louver blades, the effective ventilation area ratio e (namely the effective ventilation area ratio of the horizontal louver smoke exhaust window) of the ventilation air duct is equal to the minimum ventilation area of the ventilation air duct divided by the area of the ventilation air duct, and X is equal to N multiplied by sin alpha-N0.45; as can be seen from the above formula and fig. 18 to 21, when the upper end of the sidewall of the drainage channel 3 away from the louver blade 2 is located on the plane parallel to the louver blade 2 and the vertical distance X from the louver blade 2 is X, the vertical distance L from the upper end of the sidewall of the drainage channel away from the louver blade to the louver blade adjacent to the drainage channel is the smallest, and when the horizontal distance N between two adjacent louver blades is determined, the effective ventilation area ratio e of the ventilation duct is the smallest at this time; when the upper end of the side wall of the drainage channel 3 far away from one side of the louver blade 2 is positioned below a plane which is parallel to the louver blade 2 and has the vertical distance X with the louver blade 2, the vertical distance L from the upper end of the side wall of the drainage channel far away from one side of the louver blade to the louver blade adjacent to the drainage channel is correspondingly increased, when M is larger than or equal to L, H is larger than or equal to L, K is larger than or equal to L, and the effective ventilation area ratio e of the ventilation channel is correspondingly increased under the condition that the horizontal distance N between two adjacent louver blades is determined.

According to the above formula, the effective ventilation area ratio e of the ventilation duct is described below by experimental examples:

TABLE 1

As shown in table 1 and fig. 18 to 21, in the drainage channel 3 of experimental example 4, the upper end of the side wall on the side away from the louver 2 is located on the plane parallel to the louver 2 at the vertical distance X-sina-N0.45 from the louver 2, and as can be seen from the above, the effective ventilation area ratio e of the ventilation duct is the smallest and 45%; in the drainage channels 3 of the experimental examples 1, 2, 3, and 5, the upper ends of the sidewalls away from the louver 2 are located below the plane parallel to the louver 2 and having the vertical distance X from the louver 2, and the effective air area ratio e of the air duct is increased as compared with the effective air area ratio e of the air duct in the experimental example 4. Therefore, the effective ventilation area ratio e (namely, the effective ventilation area ratio of the horizontal louver smoke exhaust window) e of the ventilation air duct in the embodiment is more than or equal to 45%, and the ventilation air duct has obvious ventilation advantages compared with the traditional ventilator.

Specifically, when the lower end of the louver blade 2 is connected to the upper end of a side wall of the drainage channel 3, which is close to the louver blade 2, the louver blade and the drainage channel may be integrally formed. Through the above-mentioned design of shutter 2 and water drainage tank 3, can be convenient for drainage the rainwater to water drainage tank 3 in, also can ensure the effective draught area of horizontal tripe smoke vent.

Specifically, as shown in fig. 14 and 15, the bent portion 6 includes a first flange 61 connected to the upper end of the louver 2, and a second flange 62 connected to the first flange 61.

Further, a third folded edge 63 may be provided, and the third folded edge 63 is connected to the second folded edge 62.

Still further, the first folded edge 61 and/or the second folded edge 62 and/or the third folded edge 63 are arc-shaped or horizontally arranged; alternatively, one end of the first folding edge 61, the second folding edge 62 and/or the third folding edge 63, which is far away from or close to the louver blade 2, is arranged to be inclined downwards. Except for the lowest drainage groove 3, the vertical projection of the edge of each drainage groove 3 falls on the first folded edge 61, the second folded edge 62 and/or the third folded edge 63 of the bent part 6 below the drainage groove; with the structure, when water drops at the edge of the drain channel 3 drop on the first folded edge 61, the second folded edge 62 and the third folded edge 63 of the bent part 6 below the drain channel, the water drops can flow into the drain channel 3 at the lower end of the louver blade 2 along the louver blade 2, so that a large amount of rain splashing is avoided; in addition, because the first folding edge 61 and/or the second folding edge 62 and/or the third folding edge 63 are far away from or close to one end of the louver blade 2 and incline downwards, when water drops at the edge of the drainage channel 3 drop on the first folding edge 61 and/or the second folding edge 62 and/or the third folding edge 63 of the next layer, the water drops can splash towards the corresponding side (determined by the size of raindrops, the distance from the upper water tank to the folding edges and the angle of the folding edges), the direction of the downward inclination can be controlled, the splashing direction can be controlled, if the splashing is generated, the splashed rainwater is controlled to fall on the adjacent louver blade 2 or in the drainage channel 3, and thus the water drops on the drainage channel 3 are effectively prevented from falling into the room due to splashing when dropping.

Furthermore, in the same rain-proof mechanism, except for the drainage channel 3 and the louver blades 2 at the lowest layer, at least one layer of louver blades 2 and the vertical projections of the outer edges of the corresponding drainage channels 3 all fall on the louver blades 2 at the next layer or on the bending parts 6 of the louver blades 2 at the next layer or in the water tank 3 at the next layer. By the structure, when rainwater falls on the louver blades 2 on the uppermost layer, the rainwater flows into the drainage groove 3 at the lower end of the louver blades along the louver blades, if the drainage groove 3 is full of rainwater, the rainwater can fall on the lower layer of louver blades and is drained away by the drainage groove at the lower end of the lower layer of louver blades, and the rainwater cannot flow into a room after being blocked layer by layer; can improve through setting up multilayer water drainage tank the utility model discloses a drainage capacity.

Further, in the present embodiment, the vertical projection of the upper edge of any one or more layers of louvres 2 falls in the same layer of adjacent louvres 2 or the same layer of adjacent drainage channels 3; so, water droplet along the formation of water droplet then can drip on with one deck adjacent shutter plate 2 or same layer adjacent water drainage tank 3 on the below shutter plate, and can not follow and directly drip indoor between two shutter plates, improved the utility model discloses a rain-proof effect.

As another preferable mode, the vertical projection of the edge of any one or more layers of the drainage channel 3 and/or the lower end edge of the louver 2 falls on the lowermost louver 2, so that the water drops on the edge of the drainage channel 3 or the lower end edge of the louver 2 are prevented from dropping into the lowermost drainage channel 3 to cause rainwater splashing and falling into the room.
