Description

ENERGY SAVING AND MULTI-FUNCTION BLIND WINDOW}

The present invention relates to an energy-saving multifunctional blind window, and more specifically, to the indoor ventilation in a variety of ways through the interior of the window, the energy-saving multifunctional blind to minimize the heat loss of the building flow into the window through the blind It is about a window.

As is well known, windows and doors in a building serve as a wall that separates indoors from outdoors, and at the same time, it is a passage for supplying sunlight and fresh outside air, and is an essential component that makes the indoors feel a sense of view and openness.

However, the heat loss flowing through the windows is ten to tens of times higher than that of the insulation wall, which increases the heating and cooling costs, thereby increasing the maintenance cost of the building.

Therefore, high-performance insulation windows such as vacuum windows have been developed to improve the insulation and sound insulation performance of windows and doors, but they are not widely used for windows because they are expensive. Simple two-ply windows, also called paired glass, are commonly used.

In addition, in the case of a general conventional window using general transparent glass, blinds and the like should be separately installed adjacent to a window in a building in order to shield direct sunlight. There is a drawback to fly.

In addition, as buildings are enlarged and indoor air conditioning such as air conditioning and ventilation inside the building is integrated into a centralized system, most of the windows of newly constructed buildings tend to be installed as fixed windows that cannot be opened and closed freely.

Therefore, the operation cost of the air conditioning system is increased because the individual ventilation through each window is not easy and mainly depends on the heating and cooling and ventilation by the centralized air conditioning system.

Moreover, the ventilation by centralized air conditioning system, not the direct ventilation through each window, should keep the inside of the duct clean because air is circulated through the duct in the building, but it is not easy for people in the building. It has a problem that is undesirable for health.

An object of the present invention for solving the above problems, to induce the flow of air in a variety of ways through the windows to allow the ventilation of the room and to minimize the heat loss generated through the windows using the blinds Energy-saving teasers provide blind windows.
