Description

Energy-free Louver Device Using Expansive Agent

The present invention is installed on the outside of the window of the apartment house or building without a balcony and can effectively control the light according to the temperature or season without the need for power, thereby improving thermal energy efficiency and providing a comfortable indoor environment. Relates to a device.

In apartments, balconies play an important role, such as blocking direct sunlight, making the indoor environment comfortable, and preventing fire from moving to the upper floor in case of fire, and being used for evacuation in case of an emergency.

Most people, however, were using balconies as spaces for storing goods, or illegally expanding them into indoor spaces. As a result of the many illegal expansions that cannot be regulated, legislation has been legally recognized since 2006, and since the majority of apartments, balcony expansion has become commonplace.

This has the advantage of increased space, while many of the important features of the original balcony, such as fire protection, insulation and light, were lost.

As a countermeasure has been prepared, the fire protection function of the balcony has been secured to some extent by the installation of sprinkler and fire protection glass since 2008, and the insulation function is effective by improving the sealing of windows and the application of double windows.

But there are no special measures against mining,

Apartment houses without balconies are the main cause of the use of air conditioners due to the increase in indoor temperatures due to mining.In the case of electricity, the use of air conditioners in summer, which consumes the most power, is the national concern. It is a big loss, and in recent years, where energy saving and global warming prevention are emerging as a global problem, effective measures to reduce the use of air conditioners are needed.

The method of preventing the light is (1) to prevent the outdoors from the balcony or the shade, (2) to prevent the indoors from the curtains, (3) to the window using the double windows installed inside the special glass or blinds. However, the most effective way to suppress indoor temperature rise due to daylighting is to prevent it outdoors.

The easiest way to block mining outdoors in apartments without balconies is by awnings.

In the case of sunshade (1) The tent type is inexpensive and easy to install, but has the disadvantages of safety and durability problems due to the durability and appearance problems and the high-rise apartment building. Therefore, (2) louver type, which is beautiful in appearance and less influenced by wind, is used in recent years.

On the other hand, when energy efficiency is considered, it is effective to cover the sky in summer, but in the winter, the sky is good to be introduced into the room, so it is necessary to develop a method for controlling the sky according to the season.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the related art. The object of the present invention is as follows.

First, in a multi-family house without a veranda, it provides a non-powered louver device using an expansion agent that effectively adjusts the light according to the temperature or season to increase thermal energy efficiency and enable a comfortable indoor environment.

5 is a cross-sectional view illustrating a state in which the central moving plate and the central fixing plate are coupled to the outer frame in the non-powered louver device using the expanding agent of the present invention, and FIG. 6 is a conceptual diagram showing the movement of the blade according to the volume change of the expanding agent in the present invention. to be.

As shown in FIG. 5, the cylinder 270 includes an expansion chamber 273 and a cylinder chamber 271 having a larger diameter than the expansion chamber 273, and a piston 250 inside the cylinder chamber 271. ), A piston rod 213 and a spring 230 to assist the smooth driving is assembled. A cross section of the expansion chamber 273 and the cylinder chamber 270 may be polygonal, but a circular shape is most preferable for a smooth function of the piston 250.

Inside the expansion chamber 273 and the cylinder chamber 270 is filled with an expansion material 290 having a high coefficient of thermal expansion such as mercury or alcohol. When an external temperature change occurs, the volume of the expansion material 290 is changed due to the expansion agent 290, and the piston 250 moves back and forth by the pressure, thereby automatically behaving without external power support.

Therefore, the scale of the expansion chamber 273 and the cylinder chamber 270 is determined by the coefficient of thermal expansion of the expansion material 290, the piston rod 213 to make the diameter of the cylinder chamber 270 larger than the expansion chamber 273. It is more effective because it can transmit a great power to it.

The spring 230 has a function of assisting the restoration of the piston 250 when the expandable material 290 is contracted due to a decrease in temperature.

Threads may be formed on the inner circumference of the expansion chamber insertion hole 411 of the front plate 410 and the outer circumference of the expansion chamber 273 to be fastened and fixed to each other. A screw thread may be formed on the outer circumference of 273 to fasten with a bolt 500 or the like. However, such a fixing method is only an embodiment, and a conventional method such as an adhesive may be used.

6 is a conceptual diagram showing the movement of the blade according to the volume change of the expansion agent in the present invention, an explanatory diagram illustrating a mechanism for controlling the light according to the season to the outside temperature.

The left figure shows the position of the piston 250 in the cylinder 270 according to the thermal expansion of the expansion agent 290, the center figure shows the insertion of the upper center of the blade center of the central moving plate 200 in accordance with the movement of the piston 250 The positional relationship between the hole 211 and the blade center lower protrusion insertion hole 110 of the central fixing table 100 is shown, and the figure on the right shows the rotation of the blade 300 and the state of direct sunlight accordingly.

In the case of (a), the blade center upper protrusion insertion hole 211 and the blade center lower protrusion insertion hole 110 are vertically in a spring or autumn temperature state, which is the most common temperature (20-25 ° C.), called normal temperature. Located at the same position, the blade 300 maintains verticality and passes a portion of sunlight to provide a soft light condition.

In the case of (b), in a high temperature state such as hot summer, the expansion material 290 expands so that the blade upper middle projection insertion hole 211 moves to the right (reverse direction) than the blade center lower projection insertion hole 110. Blade 300 is tilted to the rear and completely blocks the sun to suppress the rise in room temperature.

In the case of (c), in the low temperature state such as winter, the expansion material 290 contracts so that the blade upper middle projection insertion hole 211 moves to the left (advance direction) than the blade center lower projection insertion hole 110 so that the blade 300 is tilted to the front and helps to increase the room temperature by introducing a lot of sunlight into the room.

However, the above-described behavior is not limited to the season, and the behavior may always occur according to the temperature change in the day, and as a result, accessories such as the cylinder 270 are left for a long time and do not cause trouble such as corrosion.
