Description

Multifunctional louver adjustable natural ventilation window

technical field

The invention relates to a ventilation facility for building doors and windows, in particular to a natural ventilation window.

Background technique

The main function of building windows is lighting and ventilation, and its ventilation is basically realized by setting movable window sashes at present. In addition, there are ventilation methods such as setting fixed shutters, natural ventilators for doors and windows, electric ventilators or ventilation fans.

The main disadvantages of movable sash ventilation are as follows: ①The set sash frame usually affects both the sight line and the appearance, and the opened sash usually also affects the building appearance; ②When the ventilation is turned on, the problems of dust prevention, insect protection and noise are unavoidable and It cannot be solved satisfactorily; ③During severe weather such as wind and rain, the ventilation cannot usually be turned on, and if it is turned on and no one is there, the consequences are usually very bad; ④Direct wind blowing is not good for human health when the wind speed is high; ⑤ There are anti-theft problems and hidden dangers of unsafe heights.

The main disadvantages of fixed louver ventilation are as follows: ① noise problems and energy-saving problems are prominent and unavoidable; ② the ventilation area cannot be adjusted.

The main disadvantages of door and window natural ventilator ventilation are as follows: ①Because its structure is similar to that of a damper, its ventilation area is limited by the use environment, and it can only meet the demand for a certain amount of fresh air to a certain extent, and it is usually impossible to completely replace the active air The window sash, so when the door and window natural ventilator is used, the movable window sash is usually set at the same time. It can be seen that the natural ventilator for doors and windows has only alleviated some disadvantages of the use of movable sash and has not really completely solved its problems. ②Limited by its ventilation area, it cannot better filter the outdoor air.

The main disadvantages of electric ventilator or ventilation fan ventilation are as follows: ①Forced ventilation is a way of energy consumption; ②Usually cannot be used during sleep; ③The installation space required for motors and fans usually affects their aesthetics.

At present, building doors usually have no ventilation requirements except for toilets, but this does not mean that ventilation is unnecessary. As we all know, when the door can be ventilated, it will form natural convection with the ventilation of the window, which is an ideal room ventilation state. However, today's related ventilation facilities are not suitable for the ventilation of the door, and the ventilation of the door is more restricted, such as living habits, privacy, safety and so on.

Contents of the invention

The technical problem to be solved in the present invention is:

Comprehensively solve the above-mentioned ventilation of building doors and windows and related problems caused by ventilation, truly realize the functional division of windows, and design pioneering and innovative ventilation facilities for building doors and windows.

The technical solution adopted by the present invention to solve its technical problems is:

The present invention is mainly composed of a louver mechanism, a side seam sealing mechanism, a drive mechanism and a frame member, and usually includes a blade drive mechanism, an insect-proof layer, and other components such as a filter layer, an indoor orifice plate, and a louver opening status indicator may be provided as appropriate.

Louver mechanism:

The louver mechanism includes louvers, sealed sound-insulating strips and blade shafts, and other related parts such as sound-insulating panels and sound-absorbing layers can also be set as appropriate.

A louver is a collective term for a group of vertically aligned louver blades arranged horizontally.

Louver is a general term for blades, special-shaped blades, blades and blade end pieces, special-shaped blades and blade end pieces.

The difference between the special-shaped blade and the blade is that it has the function of a sound insulation board.

The blade end piece is an object with a blade function arranged on the end of a blade or a special-shaped blade. Its main functions are as follows: ① When special-shaped blades are used, it can meet the needs of the side seam sealing mechanism to seal the side seam. ② When the blade is used, it can be used as a connection method between the blade and the blade shaft.

When the blade shaft is combined with the blade end piece or the blade core, etc., it is considered as the blade shaft, and when the blade shaft is the inherent conjoined part of the side frame or the blade (including special-shaped blades), its related parts are still regarded as the louver. As far as the independent blade shaft of the mechanism is concerned. The blade rotation shaft is allowed to be set along the entire width of the louvers.

The left and right ends of each louver are respectively mounted on the corresponding side frames through their respective blade rotating shafts, and each louver can rotate with the axis of the respective blade rotating shafts as the center of circle. Each louver and the vertically adjacent louvers can overlap each other horizontally, and either or both sides of the overlapped surfaces at the horizontal overlap are usually fixed (including composite) with sealing and sound insulation strips , and when the louvers are fully closed, the sealing and sound insulation strips set are deformed under pressure to achieve the required sealing and sound insulation. Between the top and bottom louvers and the corresponding upper and lower frames can be sealed and sound-insulated with sound-insulating strips, telescopic seals, mechanical seals, etc.

The shutter mechanism is usually a single-layer shutter, but double-layer shutters can also be used if necessary. The shutter mechanism is usually a single-row shutter, but multi-row shutters can also be used when necessary.

Side Seam Sealing Mechanism:

The side seam sealing mechanism refers to the mechanical structure that can tightly seal the vertical gap between the left or right side of the louver and the relevant side frame when the louver is fully closed.

The side seam sealing mechanism includes a side seam sealing strip, a side seam pressing bar and a side seam pressing mechanism. The side seam sealing strip is usually fixed vertically (including synthetically) on the side seam pressure rod, and it can also be fixedly arranged on the relevant parts of the louvers and side frames under special circumstances. When the louvers are fully closed, the side seam sealing strips are deformed by the pressure of the side seam pressure rods to achieve sealing and sound insulation for the vertical seams between the louvers and the relevant side frames.

The side seam pressure mechanism refers to the general term for the device, mechanism or object that can realize the pressure on the side seam sealing strip through the side seam pressure rod. The specific methods of the side seam pressure applying mechanism are various, and the better methods include the louver rotary type and the elastic action type.

The louver rotary type is a way to achieve the required pressure requirements by driving the movement of the side seam pressure bar through the rotation of the louver or the blade rotating shaft.

The elastic action type is a method of applying elastic force to the side seam pressing bar through a spring (spring leaf) to achieve the required pressing requirements.

In the present invention, side seam sealing mechanisms are respectively provided on the left and right sides of each louver.

When the side seam connectors in the side seam pressure mechanism are fixedly connected to each louver in the louvers or to the blade shafts on the same side of each louver, the side seam sealing mechanism can replace the blade transmission mechanism or cooperate with the blade transmission mechanism. Institutions form composite institutions.

Drive mechanism:

The driving mechanism includes a power source device and a power transmission mechanism.

Power source device refers to the general designation of devices, mechanisms or objects that transmit power to the power transmission mechanism through external force. The power source device has various specific methods, such as knob type, torsion bar type, pull cord type, crank type, electric remote control type and the like.

The power transmission mechanism refers to the use of mechanical transmission principles (including worm gear transmission, gear transmission, rack transmission, connecting rod transmission, pull wire transmission, lever transmission and other principles and their relative combinations) to transmit power to or blade shaft or blade transmission. A general term for devices, mechanisms or objects with setting positions such as rods or blades (including special-shaped blades). The specific ways of the power transmission mechanism are various, such as booster sector gear blade shaft type, booster rack drive rod type, pull wire drive rod type, booster pull wire drive rod type and the like.

The booster is a finished form of the booster mechanism in the power transmission mechanism for easy installation. The booster is usually a permanent component of the power transmission mechanism, and its main function is to use a small external force to meet the large force required to seal the sound insulation strip and the side seam sealing strip when the louvers are fully closed. . The booster usually also has the function of locking the open and closed state of the louvers. The specific methods of the booster are various, and its better methods include worm gear self-locking type and gear sliding shaft locking type.

The worm gear self-locking type is a method that utilizes the deceleration and self-locking principles of worm gear transmission. The worm gear self-locking type is usually also equipped with gear transmission to further increase its transmission ratio.

The gear sliding shaft locking type is a method of using the deceleration principle of gear transmission and the locking and unlocking principle of entering or exiting the card position generated by pushing and pulling the sliding shaft.

Frame members:

Framing members can be classified into single-frame and double-frame settings. The single-frame setting refers to a method in which only an outer frame is provided. The double-frame setting refers to a method in which an outer frame and an inner frame are provided. The main purpose of the double-frame setting is to install the filter layer and insect-proof layer on the inner frame to facilitate cleaning, replacement and other operations.

The outer frame includes an outer upper frame, an outer lower frame and an outer frame. The outer frame includes left and right outer frames, and an outer middle side frame can also be provided if necessary. The inner frame includes an inner upper frame, an inner lower frame and an inner frame. The inner frame includes left and right inner frames, and if necessary, an inner middle side frame can also be provided.

The outer upper frame and the inner upper frame are collectively referred to as the upper frame. The outer lower frame and the inner lower frame are collectively referred to as the lower frame. The outer frame and the inner frame are collectively referred to as side frames.

The frame members are fixedly mounted on window frames or doors or other objects suitable for the present invention (the inner frame may be fixedly mounted on the outer frame).

Blade drive mechanism:

The blade transmission mechanism refers to the mechanical structure of the non-side seam sealing mechanism that can drive the louvers to move in an orderly manner.

The vane transmission mechanism can usually be divided into a vane type and a vane shaft type according to its setting position. The characteristic of the vane type is that the transmission force acts on each louver except the driving louver through the vane transmission rod to drive the louver to move. The blade shaft type is characterized in that the transmission force acts on the same-side blade shaft of each louver except the driving blade shaft in the louvers through the blade transmission rod to drive the louvers to move.

The driving louvers refer to the louver blades or the corresponding blade rotating shafts of the louver blades are directly stressed by the driving mechanism. The driving blade shaft refers to the blade shaft or the corresponding louvers of the blade shaft directly acting on the blade shaft of the driving mechanism.

Whether there is a drive louver or a drive blade rotating shaft depends on the specific arrangement of the power transmission mechanism.

The concrete implementation of blade drive mechanism is varied, and its basic usual way is vertical rod type and connecting rod type. The vertical rod type must have a blade transmission rod, and usually also has a blade transmission connector and a blade transmission shaft, but there is no short rod. And its blade transmission rod and short bar of connecting rod type must be established, usually also be provided with blade transmission connecting piece, blade transmission rotating shaft.

The vane drive mechanism is optional because there are cases where it can be replaced by the side seam sealing mechanism. The blade transmission mechanism and the side seam sealing mechanism can form a combined mechanism having the characteristics of both mechanisms.

When the lateral length of the louver is large, the blade transmission mechanism can be used as a vertically movable reinforcing rib of the louver.

Filter layer:

The filter layer refers to a device or object that can filter air to prevent excessive outdoor dust from entering the room. There are advantages and disadvantages to setting up the filter layer, so it should be decided according to the circumstances.

When the filter layer is provided, the present invention can be equipped with a retractable device to hide or unfold the filter layer, so that the user can choose whether to use the filter layer or not. The retracting device refers to the same or similar setting as the principle of the scroll type or folding screen window.

Insect layer:

Insect-proof layer refers to a device or object other than the filter layer that can prevent outdoor mosquitoes from entering the room.

Insect barriers are generally a permanent component of the invention. Insect-proof layer generally adopts insect-proof net or insect-proof hole plate, and insect-proof net is preferably with thick silk insect-proof net again (because the present invention has no daylighting, does not have line-of-sight requirement, so need not be limited to the gauze that usually uses).

The insect-proof orifice refers to a plate-shaped object densely covered with small holes that cannot allow mosquitoes to pass through.

Coarse wire insect net refers to a net-like object made of thicker filamentary material (usually stainless steel wire) that can prevent mosquitoes from passing through. Thick wire insect nets usually do not need to be replaced and have better anti-theft properties.

Indoor orifice:

The indoor orifice plate is a plate-shaped object with openings for aesthetic needs, wind direction restriction needs, noise prevention needs, etc.

Sometimes the insect-proof orifice can replace the indoor orifice, and sometimes the thick wire insect-proof net can also replace the indoor orifice.

Louver open status indicator:

The louver opening state indicator refers to the general designation of devices, mechanisms or objects that can visually display the opening degree of the louvers (when the louvers are completely closed, the degree of opening is counted as zero).

The louver opening state indicator is set because it is difficult for the power source device to display the opening degree of the louvers when the transmission ratio of the driving mechanism is large, and when there is a filter layer, an insect-proof layer, and an indoor orifice plate, there are problems that cannot be seen or seen from the room. It is inconvenient to see the opening degree of the louvers intuitively, so the louver opening status indicator is used to solve the problem.

When the transmission ratio of the driving mechanism is small, the power source device can sometimes replace the louver opening status indicator, and when the opening degree of the louver can be easily seen from the room, the louver opening status indicator may not be provided.

Anti-theft function:

Relevant materials used in the relevant parts of the frame member and louver mechanism (including the material used to cross the anti-theft strip in the hole of the louver), the relevant materials used in the relevant parts of the frame member and the insect-proof layer, and the relevant parts of the indoor orifice plate The anti-theft function of the present invention can be realized if the relevant materials adopted have sufficient anti-theft properties.

Anti-noise settings:

The present invention can be divided into a closed sound insulation mode and a full-range sound insulation and absorption mode according to the effective working period of its anti-noise setting.

The closed sound insulation method refers to a method that can greatly reduce the outdoor noise introduced into the room only when the louvers are completely closed. The closed sound insulation method usually mainly realizes the noise prevention requirements by sealing the sound insulation strip and the side seam sealing strip, but some other noise prevention measures can also be taken.

The whole sound insulation method refers to the method that can greatly reduce the outdoor noise introduced into the room when the louvers are closed and open. In addition to the sound insulation strips and side seam sealing strips, the noise prevention measures that can be taken in the whole process of sound insulation and absorption mainly include: ① take louver layer anti-noise measures; ② set the sound-absorbing layer of the outer frame and adopt an outer frame whose shape is conducive to noise prevention; ③Set the indoor orifice plate sound-absorbing layer and adopt the shape of the indoor orifice plate that is conducive to noise prevention; ④The main sound-transmitting objects use sound-insulating insulating pads, using rotating shaft sound-insulating insulating parts, etc. The anti-noise measures of the louver layer mainly include: ① use special-shaped blades or add sound insulation panels to the blades; The sound insulation board adopts double-layer louvers; ④The shape of the special-shaped blade or the sound insulation board added to the blade should be conducive to noise prevention and so on. The implementation form of the specific noise prevention measures for the whole sound insulation and absorption method should be selected and combined according to the degree of noise reduction requirements.

The anti-noise reflective surface refers to the shape surface whose shape surface has the function of reflecting the sound wave acting on it to the direction that is beneficial to indoor noise prevention.

The beneficial effects of the present invention are:

The functional division of windows is truly realized in an environmentally friendly and energy-saving manner, and the diversity of optional components in the present invention can ensure that various use requirements are met, providing a brand-new field for the production and operation of doors and windows, and making the development of doors and windows more promising. The revolutionary progress has established a good platform for improving the quality of people's living and working environments.

Booster 25 has adopted the worm gear self-locking type. The booster 25 is fixedly installed on the window frame 9 and the outer frame 20 . The booster 25 not only adopts the deceleration and self-locking principle between the booster worm 34 and the booster worm gear 32, but also adopts the deceleration principle between the multi-stage booster gears 31, so that a larger transmission ratio can be obtained to make it The relevant operation of the knob 26 is easy and labor-saving.

The present embodiment adopts closed sound insulation mode.

The brief working principle of this embodiment is: manpower rotates the knob 26 to transmit the power to the booster 25, and the booster 25 transmits the power to the sector gear 24 at the same time, and the sector gear 24 transmits the power to the Drive the louvers, and the driven louvers transmit the power to the blade transmission mechanism 2 and the side seam sealing mechanism 3 at the same time, the blade transmission mechanism 2 drives all other louvers except the driving louvers at the same time, and the side seam sealing mechanism 3 also Simultaneously drive other related louver actions besides driving the louvers, and the rotation of the louvers can simultaneously drive the related motions of the side seam sealing mechanism 3 and the blade transmission mechanism 2 . The worm gear self-locking booster 25 can ensure that the louvers stay at any position in the set area.
