Description

Multifunctional window

Technical Field

The invention relates to the technical field of indoor natural ventilation, in particular to a multifunctional window.

Background

In twenty-first century, countries all over the world face great challenges of sustainable development, energy crisis, indoor environmental pollution and the like are increasingly increased, and energy conservation and emission reduction become the consistent direction of common efforts of the whole society. In recent years, building energy consumption, industrial energy consumption and transportation energy consumption are three major forces of energy consumption in China, and research data show that the building energy consumption accounts for about 30% of total energy consumption, wherein fresh air load in a building accounts for about 30% -40% of the total energy consumption of the building. The excellent natural ventilation design can greatly reduce the energy consumption of the building, and can also provide fresh and clean natural air, and the oxygen content and the humidity of the air in a natural ventilation room under the window opening condition are closer to the outdoor, so that the indoor air is more beneficial to the physiological and psychological health of people compared with the indoor air under the intervention of manual equipment. Therefore, the natural ventilation of the window of the building has important significance for building energy conservation and personnel thermal comfort.

Natural ventilation of a building is not a simple matter, most areas of China are in a monsoon climate, wind directions and wind speeds are changeable all the year round, and therefore, the natural ventilation of the building through windowing is fully considered to adapt to the influence of the change of the natural wind directions and the wind speeds. At present, common window opening modes comprise a flat-open window, an upper (lower) suspended window and a sliding window.

The flat-open window has simple structure, large ventilation area and high ventilation efficiency. However, the method has the defects of poor adaptability to high wind speed and wind direction, high potential safety hazard in use in severe conditions such as high wind speed, rainy days and the like, and when the wind force is high, the outward opening window sash facing the wind is easy to swing along with the wind, easy to fall off or enter the rain indoors and the like, and when the window sash is opened inwards, the larger indoor space is occupied, so that the usability of the window sash is very influenced.

Top (bottom) hung windowing is a relatively modern windowing approach, but has evolved from the original windowing approach. The window has the characteristics of better control of opening angle, small occupied area, convenient opening, good adaptability to high wind speed and stronger adaptability to multiple wind directions. The upper-suspended out-opening window mode can also effectively shade sun and prevent rain from drifting, is very suitable for ventilation of high-rise buildings, but has poor adaptability to low wind speed, and leads to the reduction of natural ventilation efficiency.

The sliding window is the most common and universal window opening form of modern houses, and has the advantages of small occupied space, simple structure, convenient use, firmness and durability. But has the defects of poor adaptability to wind direction and wind speed in construction, no wind guiding effect, and half of the opening area of the casement window under the condition of the same design area. Therefore, the ventilation efficiency of the sliding window is the lowest among the three window opening modes.

Any structural modification, proportional change or size adjustment should still fall within the scope of the disclosure without affecting the efficacy and achievement of the present invention. Moreover, the drawings only show the components related to the present invention, not the number, shape and size of the components in actual implementation, the form, number and proportion of each component in actual implementation can be changed arbitrarily, and the layout of the components may be more complex.

Referring to fig. 1 to 6, fig. 1 is a multi-functional window according to an embodiment of the present invention, including: a first window frame 100, the first window frame 100 also being referred to as a window casing, for fixed mounting on a wall; a second window frame 200, the second window frame 200 being located within the first window frame 100, the second window frame 200 also being referred to as a window inner frame for glazing; it will be appreciated that, in all types of existing windows, the first window frame 100 and the second window frame 200 are basically included, and the window frames may be made of aluminum alloy, plastic steel or bridge-cut aluminum, etc., so that the most suitable window materials may be determined according to specific building characteristics and use requirements.

Unlike the conventional window in the prior art, in this embodiment, two adjacent edges of the second window frame 200 are hinged to the first window frame 100 by a detachable hinge unit, and the two adjacent edges herein can be understood as one side and an upper (lower) side, when the side of the second window frame 200 is hinged to the first window frame 100, the window becomes a flat-open window, and when the upper (lower) side of the second window frame 200 is hinged to the first window frame 100, the window becomes an upper (lower) suspended window, so that one of the window opening modes can be arbitrarily selected according to weather conditions, wind power and use requirements. Also, in order to prevent the hinge unit on one side from affecting the second window frame 200 to be opened along the other side, a separable hinge unit is employed in the present embodiment, that is, when one side of the second window frame 200 is hinged to the first window frame 100, the hinge unit on the other side is in a separated state.

The window further includes a driving unit 400 for driving the hinge unit to hinge or separate so that the opening mode of the window can be adjusted. The window further includes a locking unit which restricts the movement of the hinge unit when the second window frame 200 is opened, and when the second window frame 200 is opened, if the hinge unit is also moved, the hinge unit of the second window frame 200 is driven to a separated state, which easily causes the second window frame 200 to be detached, endangering pedestrians and objects.

As can be appreciated, there are various structures of the separable hinge unit, when the second window frame 200 is hinged to the first window frame 100 by a hinge (also referred to as a hinge), the hinge provided on the first window frame 100 is hinged to the hinge provided on the second window frame 200 by a hinge shaft, and when the hinge shaft is drawn out from the two hinges, the two hinges are separated. In addition, or alternatively, the hinge unit is detachable by controlling the extension and retraction of the rotation shaft 300 and the hole 110, which is adopted in a preferred embodiment of the present invention, which will be discussed in detail below.

It will be appreciated that the driving unit 400 may be a mechanical structure, powered by user operation, to effect articulation or separation of the articulation unit; the electric structure can also be adopted, power is provided through electric energy, the hinging and the separation of the hinging unit are realized according to the instruction of a user for pressing the switch, and a built-in power supply or an external power supply is needed in the window by adopting the structure. Similarly, the locking unit can also be of a mechanical structure or an electric structure and can be arranged according to actual requirements.

It will be appreciated that when the user is in daily use, one of the edges of the second window frame 200 should be hinged to the first window frame 100, i.e. corresponding to two window opening modes. When the user leaves home for a long time, and needs to ensure safety, two adjacent edges of the second window frame 200 can be hinged to the first window frame 100, and the window can be safely locked. When a user desires to clean a window, both adjacent edges of the second window frame 200 can be separated from the first window frame 100, and at this time, the second window frame 200 can be removed for cleaning.

The window is hinged on the first window frame 100 by enabling the two edges of the second window frame 200 to be detachably hinged, so that the driving unit 400 controls the hinging unit to be hinged or separated, and the fact that only one edge of the second window frame 200 is hinged on the first window frame 100 at any moment can be achieved, normal opening of the window is achieved, in addition, the opening effect of the flat-open window and the upper (lower) suspended opening window can be achieved by converting the hinged edge of the second window frame 200, different opening modes can be selected according to requirements under different scenes, the setting of the locking unit is achieved, the opening safety is improved, and falling of the second window frame 200 caused by the action of the driving unit 400 during opening can be avoided.

In an embodiment of the present invention, the hinge unit includes a rotation shaft 300 and a hole 110, and the hinge unit is formed by the rotation shaft 300 and the hole 110, so that the hinge unit can be hinged and separated only by controlling the extension and retraction of the rotation shaft 300, which is very convenient to control. One of the rotation shaft 300 and the hole 110 is provided on the first window frame 100, and the other is provided on the second window frame 200, i.e., the rotation shaft 300 may be provided on the first window frame 100 and the hole 110 may be provided on the second window frame 200, or the rotation shaft 300 may be provided on the second window frame 200 and the hole 110 may be provided on the first window frame 100. The driving unit 400 is used for driving the rotating shaft 300 to be inserted into or separated from the hole 110. The hinge structure is not selected in this embodiment because the position of the hinge shaft is fixed and the hinge shaft is located outside the first window frame 100 and the second window frame 200, so that the structure is somewhat complicated when the hinge shaft is controlled to operate. The rotation shaft 300 may be directly provided to the first window frame 100 or the second window frame 200, so that the driving unit 400 may be provided in the first window frame 100 or the second window frame 200.

In an embodiment of the present invention, the locking unit includes a protrusion and a limiting groove 310, one of the protrusion and the limiting groove 310 is disposed on the rotating shaft 300, and the other is disposed on the hole 110, for example, the limiting groove 310 may be disposed on the rotating shaft 300 and the protrusion may be disposed on the hole 110, or the protrusion may be disposed on the rotating shaft 300 and the limiting groove 310 may be disposed on the hole 110. The limiting groove 310 comprises an axial groove 311 and a circumferential groove 312, when the second window frame 200 is closed, the axial groove 311 and the protruding portion form a key groove fit, so that the rotating shaft 300 can be freely inserted into the hole 110, and the circumferential groove 312 avoids the protruding portion when the rotating shaft 300 is inserted into the hole 110. The specific structures of the axial groove 311 and the circumferential groove 312 are shown in fig. 6.

When the second window frame 200 is closed in the first window frame 100, the protruding portion and the axial groove 311 form a key slot to cooperate, so that the extension and retraction of the rotation shaft 300 are not limited, and the rotation of the rotation shaft 300 is limited by the protruding portion in the extension or retraction process of the rotation shaft 300, so that the user can avoid the error opening of the second window frame 200 in the extension or retraction process of the rotation shaft 300. Only when the rotating shaft 300 is fully extended, the protruding portion is just located at the position of the circumferential groove 312, at this time, the second window frame 200 can be normally opened, and in the opening process of the second window frame 200, the groove wall of the circumferential groove 312 and the protruding portion form a limit fit, so that the extension and retraction of the rotating shaft 300 are limited, that is, when the second window frame 200 is opened, the rotating shaft 300 is locked, and the falling of the second window frame 200 caused by the retraction of the rotating shaft 300 in the opening process of the second window frame 200 can be avoided.

It should be understood that the protruding portion may be a protrusion 120 disposed on the rotating shaft 300, or may be a protrusion 120 disposed on an inner wall of the hole 110, in an embodiment of the present invention, a through hole 111 is formed on a peripheral wall of the hole 110, a pin is inserted into the through hole 111, an inner end of the pin extends into the hole 110 to form a protruding portion, and the protruding portion is sized to fit the axial slot 311. The protruding portion is formed by the pin, so that the window can be conveniently installed, and the pin can be installed in the through hole 111 after the window is installed. The pin and the through hole 111 may be screw-fitted to facilitate disassembly.

It will be appreciated that the circumferential groove 312 may be a C-shaped groove or may be an annular groove 201, and preferably has a C-shaped groove structure, so that the window opening angle of the second window frame 200 may be limited.

The locking unit adopts a mechanical structure, so that the number of related parts is very small, and only the protruding part and the limiting groove 310 are required to be arranged, so that the locking unit is very reliable and very stable to use, and is not easy to fail. The locking unit is very ingenious in structure, can automatically realize the axial or circumferential locking limit of the rotating shaft 300 according to the windowing process of a user, does not need redundant other operations of the user, can realize automatic locking only by normally opening and closing a window of the user, and is very convenient.

In an embodiment of the present invention, one of the first and second window frames 100 and 200 is provided with a protrusion 120, the other is provided with a groove 201 which is matched with the protrusion 120, and at least one protrusion 120 or groove 201 is provided on two adjacent edges of the second window frame 200 hinged with the first window frame 100. When one of the rotation shafts 300 or the holes 110 is provided at one edge of the second window frame 200, the adjacent other edge is not well provided, and the protrusions 120 and the grooves 201 are provided for convenience in the other rotation shaft 300 or the holes 110 at the other edge of the second window frame 200, and in particular, may be provided on the mating surfaces of the protrusions 120 and the grooves 201.

It will be appreciated that it is also possible to dispense with the projection 120 or the recess 201 and to stagger the two sets of shafts 300 or holes 110 in a direction perpendicular to the window glass. Alternatively, a protrusion 120 or a groove 201 may be provided on each of two adjacent edges of the second window frame 200, and a set of rotation shafts 300 or holes 110 may be provided on each protrusion 120 or groove 201, respectively.

Depending on the location of the through holes 111 and holes 110, and the location of the protrusions 120 and recesses 201, the window according to the present invention may be freely combined with many embodiments. Taking an embodiment shown in the drawings as an example, in this embodiment, a groove 201 is formed on the upper side edge of the second window frame 200, a set of rotating shafts 300 are formed on the groove wall of the groove 201, a protrusion 120 is formed on the upper side edge of the first window frame 100, and a set of holes 110 are formed on two sides of the protrusion 120.
