Description

Horizontal shutter smoke exhaust Technical field

The invention relates to the field of ventilation equipment, in particular to a horizontal louver smoke exhaust window.

Background technique

Blinds are a style of windows that originated in China. Blinds can be used as a decoration, but also play a role in ventilation and light transmission, often used in modern buildings. Traditional blinds are designed vertically, which is not suitable for some large factories, workshops or warehouses. In order to solve the above problems, the Chinese invention patent with application number 201110213427.6 discloses a parallel air duct type natural ventilator, which is specifically composed of a skeleton, at least two sets of rainproof plates, and a lower edge of the lowermost set of rainproof plates. However, after a long period of testing, the parallel air duct natural ventilator disclosed in this patent mainly has the following problems; the parallel air duct natural ventilator is only at the bottom Drainage troughs are provided under the lower edge, and in order to reduce the effect of blocking the airflow, the water troughs cannot be widened. In this structure, if heavy rain is encountered, a large amount of rainwater will be collected into the drainage troughs, and rainwater will easily overflow from the water trough. Fall into the room; if the drainage groove is widened in order to meet the drainage requirements, the widened drainage groove will obviously block the airflow, so that the effective ventilation area of the ventilator becomes sharply smaller and cannot meet the ventilation requirements; if the drainage groove is If the depth is deep, it will not only affect the appearance of the ventilator, but also reduce the bearing performance of the ventilator frame. In order to improve the bearing performance, it is necessary to greatly increase the thickness of the frame, which will not only increase the material cost, but also It will bring other engineering problems that are difficult to deal with during installation. In addition to the above problems, there are some other problems with this parallel duct natural ventilator, such as:

(1) The effective ventilation area of the ventilator refers to the smallest area through which the airflow passes; the effective ventilation area ratio refers to the ratio of the effective ventilation area of the ventilator to the area of the ventilator (or roof opening area). Although the patent with the application number 201110213427.6 proposes in the specification that "the effective ventilation area is greater than 80% of the roof opening area", it does not disclose other relevant information greater than 80%. According to the information in the drawings of the published specification, the horizontal distance that the air can circulate in the ventilation air duct between the two adjacent rain plates is very large, which is greater than 80%. If the horizontal distance of the upper two air ducts is negligible for rain The effect of the thickness of the board itself is 100%. The bottom layer of the rainproof board is calculated according to the horizontal distance. Only the width of the bottom surface of the sink can directly block the airflow. If the horizontal distance of the ventilation air channel can be used as the horizontal distance For the effective ventilation width, the effective ventilation area of the patent can be greater than 80%; however, when actually calculating the effective ventilation area of the ventilation air duct, the length of the air duct is multiplied by the narrowest width between the air ducts, that is The minimum distance that can be ventilated (ie, the vertical distance); in this patent, the drainage slot is located below the lower edge of the bottom set of rainboards, and the placement of the drainage slot will block the airflow and reduce the ventilation duct The effective ventilation area makes the vertical distance between the ventilation ducts for ventilation smaller, which in turn reduces the effective ventilation area of the entire ventilator. According to the calculation method of the effective ventilation area, the figures 1 and 5 of the patent disclosure have an effective ventilation area ratio of 39% to 41%; and figure 3 has an effective ventilation area ratio of 34% to 37% between. The information disclosed in this patent does not specify a technical solution that can achieve an effective ventilation area ratio of 80% and at the same time achieve a good waterproof effect. In actual use, the technical solution with a large effective ventilation area ratio is favored in the market. According to the information disclosed in this patent, a ventilator whose effective ventilation area is 30% to 40% of the effective ventilation area on the market has no obvious advantage in ventilation.

(2) When the parallel air duct type natural ventilator is used, if rainwater directly hits the front of the second layer rainproof plate, rainwater will splash on the backside of the second layer rainproof plate to form water droplets, and the water droplets are adsorbed on the second The back of the rainproof board and falling along the inclined direction of the rainproof board will fall directly at any position (related to rainfall, wind speed, wind force and other factors), because the third rainproof board is in contact with the third layer. The adjacent water tanks are not connected, and the water droplets will directly drop into the room through the gap between the third layer rainproof plate and the adjacent water tank, so that its rainproof performance does not meet the requirements.

(3) When rainwater hits directly on the second rainproof plate, the generated splashing rain will directly enter the room through the gap between the third rainproof plate and the adjacent water tank under the action of wind force, making it The rainproof performance does not meet the requirements.

(4) The water on the front surface of the second layer rainproof plate flows downward in an oblique direction, and dripping on the front surface of the third layer rainproof plate will cause a small splash of rain to fall indoors, making its rainproof performance not up to the requirements.

(5) When in use, water droplets will be generated on the skeleton, and the water droplets will drip down into the room along the skeleton, so that its rainproof performance does not meet the requirements.

(6) The weight of the entire parallel air duct type natural ventilator is supported by the skeleton, and the skeleton is installed on the base. This requires increasing the number of bases, which will not only increase the material cost, but also increase the installation of the ventilator. Difficulty.

Due to the above-mentioned problems with the parallel air duct type natural ventilator, the ventilator cannot be promoted.

In addition, the utility model patent with the application number 201520394299.3 discloses a horizontal rainproof and ventilated blind. As a ventilated blind, the ventilation and rainproof performance is a key function. The patent also does not disclose information on the effective ventilation area. The patent's rainproof performance There are also major defects. In strong winds, heavy rains, and heavy rains, the wind direction is random, and the installation method of the blinds must meet the conditions of use. It cannot be selected, so that the rainwater enters the blinds with the wind direction, and directly hits the middle and lower parts of the blinds. At this time, splashing rain must occur, and the splashing rain will directly enter the interior of the room, and will also splash on the front of the adjacent louver, and pool into the room, so the shortcomings of this patent are obvious.

Based on this, how to solve the above-mentioned problems is currently the top priority.

As shown in FIG. 1, the horizontal louver smoke exhaust window of the present invention includes at least two supporting frames 1 disposed oppositely, and at least two rainproof mechanisms disposed between the two opposing supporting frames 1. In specific use, all the supporting framework 1 and the rainproof mechanism are enclosed in an outer protective plate, which is a rectangular frame body. The outer protective plate can prevent rainwater from entering the room from the side of the blinds, and can be installed by screws or rivets during installation Fix the entire outer shield on the support frame 1.

In this embodiment, the number of supporting frames 1 is two and is relatively arranged, and the number of rainproof mechanisms can be set to 12 and are arranged in sequence between two supporting frames 1 in the horizontal direction.

Specifically, the rainproof mechanism includes at least two layers of louvers 2 arranged in order from top to bottom, and a drainage groove 3 respectively provided at the lower end of each layer of louvers 2, as shown in FIG. 1. In this embodiment, each rainproof mechanism includes three louvers 2, and the three louvers 2 are arranged in order from top to bottom. Radiation at any angle from any point on the horizontal plane where the upper end of the uppermost louver 2 is located, the rays are incident on the louver 2 or the drainage groove 3 of any rainproof mechanism, so the rain cannot be Enter the room directly through the louver 2.

The shapes of the louvers 2 and the drain groove 3 on the two adjacent rainproof mechanisms are the same, and the louvers 2 on the same layer in the two adjacent rainproof mechanisms are parallel to each other, and the same in the two adjacent rainproof mechanisms The drainage grooves 3 of the layers may be parallel to each other. That is, the shapes of the uppermost louvers and the drain groove 3 of the two adjacent rainproof mechanisms are the same and parallel to each other, and the shapes of the louvers and the drain groove 3 of the middle layer are the same and parallel to each other. The shapes of the water tanks 3 are all the same and parallel to each other.

Further, at least two adjacent upper and lower louvers 2 in the same rainproof mechanism have opposite tilt directions or different tilt angles.

As a solution, the louvers 2 of one layer in the same rainproof mechanism are perpendicular to the horizontal plane and the louvers 2 of the remaining layers form an acute angle with the horizontal plane, as shown in FIG. 12.

As a preferred solution, as shown in FIG. 23, one of the rainproof mechanisms includes at least three layers of louvers 2, and in the same rainproof mechanism, the upper end of the louvers 2 and the drainage groove 3 on the upper layer Connected, so that the rainproof mechanism forms an overall structure; specifically, the upper end of the louver 2 is connected to the left or right side or the middle of the drainage groove 3 of the upper layer, and the connection position can be set according to the actual situation; in this solution One rain mechanism has three louvers 2.

As another preferred solution, as shown in FIGS. 1, 11, and 16, the louver 2 forms an acute angle α with the horizontal plane, and the lower end of the louver 2 of the same layer and the side of the drain groove 3 near the louver 2 The upper end of the wall is connected or located above the side wall of the drain groove 3 close to the louver 2 side or extends into the drain groove 3, and the upper end of the side wall of the drain groove 3 away from the louver 2 side is located The vertical distance of the louver 2 is X and parallel to the louver 2, as shown in FIG. 16; or the upper end of the side wall of the drain groove 3 away from the louver 2 is located perpendicular to the louver 2 Below the plane where the distance is X and parallel to the louver 2, as shown in FIG. 17; in this embodiment, 30°≤α≤80°; X=N*sinα-N*0.45, where N is two adjacent The horizontal distance between the louvers can be set according to the length of the smoke exhaust window.

As another preferred solution, as shown in FIG. 1, the louver 2 is provided with reinforcing ribs 4, and/or the upper end of the louver 2 forms one or more bending portions 6, so that the louver 2 can be increased. The strength of the blade 2.

In the above structure, a ventilation duct is formed between two louvers 2 on the same layer of two adjacent rain protection mechanisms and between two drainage grooves 3 on the same layer; when calculating the minimum ventilation area of the ventilation duct Actually, the vertical distance L from the upper end of the side wall of the drain groove 3 away from the louver 2 to the louver 2 adjacent to the drain groove 3, the vertical distance M between two adjacent drain grooves 3, the phase The vertical distance H between two adjacent louvers 2 and the minimum value of the shortest vertical distance K between the end of the bending part and the adjacent louvers are calculated to calculate the width of the ventilation duct, and then multiply the width of the ventilation duct In this way, the length of the ventilation duct is equal to the effective ventilation area of the ventilation duct, and the sum of the effective ventilation areas of all the ventilation ducts is the effective ventilation area of the louver smoke exhaust window. As shown in FIGS. 18 to 21, in this embodiment, M≥L, and H≥L, K≥L, the specific values of M, H, L, and K can be set according to the actual situation, so in this embodiment is The effective ventilation area ratio e of the ventilation duct is calculated from the vertical distance L of the upper end of the side wall of the drain groove 3 away from the louver 2 to the louver 2 adjacent to the drain groove 3.

In addition, the vertical distance between two louvers is H=N*sinα. According to the above formula, when the value of N is fixed, the larger the angle of α, the greater the vertical distance H between the two louvers, the vertical distance X =N*sinα-N*0.45 is also greater, when M≥L, H≥L, K≥L, and the upper end of the side wall of the drain groove 3 away from the louver 2 is located at a vertical distance from the louver 2 When it is X and is below the plane parallel to the louver 2, the effective ventilation area ratio e that the ventilation duct can achieve is greater.

When M≥L, and H≥L, K≥L, the effective ventilation area of the ventilation duct (minimum ventilation area) = the upper end of the side wall of the drainage groove away from the louver side to the louver adjacent to the drainage groove Vertical distance L × length of ventilation duct, area of ventilation duct = horizontal spacing between two adjacent louvers N × length of ventilation duct, ratio of effective ventilation area of ventilation duct e (ie horizontal louver smoke exhaust The effective ventilation area ratio of the window) = the minimum ventilation area of the ventilation duct ÷ the area of the ventilation duct, X = N*sinα-N* 0.45; as can be seen from the above formula and figures 18 to 21, when the drain 3 is far from 100 When the upper end of the side wall of the blade 2 is located on a plane parallel to the louver 2 at a vertical distance of X from the louver 2, the upper end of the side wall of the drain groove away from the louver side is opposite to the drain groove The vertical distance L of the adjacent louver is the smallest. When the horizontal distance N between the adjacent two louvers is determined, the effective ventilation area ratio e of the ventilation duct is the smallest; when the drain groove 3 When the upper end of the side wall away from the louver 2 is located at a vertical distance X from the louver 2 and parallel to the louver 2, the upper end of the side wall in the drain groove away from the louver 2 reaches The vertical distance L of the louvers adjacent to the drainage channel increases accordingly. When M ≥ L, and H ≥ L, K ≥ L and the horizontal distance N between the two adjacent louvers is determined, the effective air duct The ventilation area ratio e increases accordingly.

According to the above formula, the following describes the effective ventilation area ratio e of the ventilation duct with an experimental example:

 	N	α	L	K	M	e
Experimental Example 1	100cm	80°	50cm	50cm	50.7cm	50%
Experimental Example 2	150cm	65°	120cm	120.1cm	120cm	80%
Experimental Example 3	150cm	70°	135cm	135.3cm	135cm	90%
Experimental Example 4	150cm	30°	67.5cm	67.6cm	110cm	45%
Experimental Example 5	150cm	30°	72cm	73.5cm	110cm	48%

Table 1

According to Table 1 and FIGS. 18 to 21, the upper end of the side wall of the drain groove 3 of the experimental example 4 away from the louver 2 is located at a vertical distance from the louver 2 of X=N*sina-N*0.45 And on the plane parallel to the louver 2, according to the above, the effective ventilation area ratio e of the ventilation duct at this time is the smallest, which is 45%; the drainage groove 3 of the experimental examples 1, 2, 3, and 5 is far away The upper end of the side wall of the louver 2 is located below the plane at a vertical distance X from the louver 2 and parallel to the louver 2, and the effective ventilation area ratio e of the ventilation duct is higher than that of the experimental example 4 The effective ventilation area ratio e of the air duct has increased. It can be seen that the effective ventilation area ratio e of the ventilation duct in this embodiment (that is, the effective ventilation area ratio of the horizontal louver smoke exhaust window) e ≥ 45%, which has obvious ventilation advantages compared with the traditional ventilator.

Specifically, when the lower end of the louver 2 is connected to the upper end of a side wall close to the louver 2 in the drain groove 3, the two may be integrally formed. Through the above-mentioned design of the louver 2 and the drainage groove 3, the rainwater can be easily drained into the drainage groove 3, and the effective ventilation area of the horizontal louver smoke exhaust window can also be ensured.

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

Further, in this embodiment, a third hem 63 may be provided, and the third hem 63 is connected to the second hem 62.

Still further, the first hem 61 and/or the second hem 62 and/or the third hem 63 are curved or horizontally arranged; or, the first hem 61 and/or the second hem One end of the side 62 and/or the third flange 63 that is far away from or close to the louver 2 is inclined downward. Except for the lowermost drainage channel 3, the vertical projection of the edge of each remaining drainage channel 3 falls on the first fold 61 and/or the second fold 62 and/or the third fold of the bend 6 below it On the edge 63; by the above structure, when the water droplets at the edge of the drainage groove 3 drip onto the first folded edge 61 and/or the second folded edge 62 and/or the third folded edge 63 of the bent portion 6 below it Will flow into the drainage groove 3 at the lower end of the louver 2 along the louver 2 without generating a lot of splashing rain; in addition, due to the first hem 61 and/or the second hem 62 and/or the third hem 63 The end away from or close to the louver 2 is inclined downward, when the water droplets at the edge of the drainage groove 3 drip onto the first fold 61 and/or the second fold 62 and/or the third fold 63 of the next layer Afterwards, it may splash to the corresponding side (determined by the size of the raindrops, the distance from the upper sink to the flange, and the angle of the flange). Control the direction of the downward slope, which can control the direction of the splash. The rainwater falls on the adjacent louver 2 or the drainage groove 3, which effectively prevents the water droplets on the drainage groove 3 from falling into the room due to splashing when they drop.

Further, in the same rain protection mechanism, except for the lowermost drain groove 3 and the louver 2, at least one layer of louver 2 and the corresponding vertical projection of the outer edge of the drain groove 3 fall on the next layer The louver 2 or the layer below it is in the sink 3 on the bent part 6 of the louver 2 or below it. With the above structure, when the rainwater falls on the uppermost louver 2, the rainwater flows along the louver into the drain groove 3 at the lower end thereof. If the rainwater in the drain groove 3 is full, the rainwater will fall down The louvers of the first layer are drained by the drainage groove at the lower end of the louvers of the next layer. After being blocked by the layers, the rainwater cannot flow into the room; the drainage capacity of the present invention can be improved by providing the multilayer drainage grooves.

Further, in this embodiment, the vertical projection of the upper edge of any one or more louvers 2 falls on the adjacent louvers 2 in the same layer or the adjacent drainage groove 3 in the same layer; thus, the water mist is at the bottom The water droplets formed on the upper edge of the louver will drop on the adjacent louver 2 on the same layer or the adjacent drainage groove 3 on the same layer, and will not directly drop into the room from between the two louvers. The rainproof effect of the present invention.

As another preferred solution, the vertical projection of the edge of any one or more layers of drain grooves 3 and/or the lower edge of the louver 2 falls on the lowermost louver 2, thereby preventing the edge of the drain groove 3 or the louver 2 The water droplets on the lower edge of the drop fall into the lowermost drain groove 3 to cause rainwater to splash and fall into the room.

As a preferred solution, the lowermost drain groove 3 in any one or more rain prevention mechanisms is a bearing water tank 8, and the lower edge of the bearing water tank 8 is lower than the lower edges of the remaining lowermost drain grooves 3, such as Figures 5 and 6 show. The load-bearing water tank 8 is fixed to the base during use, and the drain groove 3 and the load-bearing water tank 8 in the lowermost layer of the rainproof mechanism in this embodiment are spaced apart from each other.

Specifically, as shown in FIGS. 7 and 8, the bearing water tank 8 includes a tank body 81 and a support portion 82 connected to the upper end of the tank body 81; the support portion 82 may be provided as two, and the two support portions 82 are bent The folding direction can be the same or opposite.

Correspondingly, as shown in FIGS. 3 and 6, the supporting frame 1 is provided with a bearing sink installation hole 7, which can be used to install the bearing sink; therefore, the bearing sink installation hole 7 The position corresponds to the position of the bearing sink 8. As shown in FIGS. 3 and 4, the bearing trough installation hole 7 is provided with a groove 71 matching the support portion 82. When the bearing trough 8 is installed in the bearing trough installation hole 7, the support portion 82 extends Into the groove 71. The lower part of the load-bearing sink installation hole 7 may be closed, as shown in FIG. 3; in addition, as shown in FIG. 4, the lower end of the load-bearing sink installation hole 7 may also be flat with the lower edge of the support frame 1, that is, the bearing The lower part of the force sink installation hole 7 may be open as shown in FIGS. 4 and 5, so after the force sink 8 is installed on the force sink installation hole 7, its lower end can be level with the lower edge of the support frame 1 to make the load bearing The sink 8 plays a better supporting role.
