Description

Ventilation efficiency improved system security window

The present invention relates to a system window, and more particularly, to a system window of a structure capable of improving the ventilation efficiency of a window opening a fine gap compared to the prior art.

Window is a representative composition that divides indoor and outdoor based on the installed building. Windows are classified according to purpose, shape, structure, and location, and they perform important functions in architectural design as well as functional aspects.

One of the most important functions of windows is lighting. The designer can select it according to the area of the window and the transmittance of light inside the window frame, and the profile related to the lighting can be easily adjusted even with a simple design change. In addition, the lighting can be controlled by adding a light blocking configuration such as curtains or blinds installed around the window separately from the windows.

Ventilation is one of the functions of windows and doors as important as lighting. Ventilation is a phenomenon in which indoor air and outdoor air are exchanged when a window is opened, and in order to realize this, the occupant of a building opens the window to ventilate it.

However, when ventilating in the above manner, as air is exchanged, heat exchange between the outside air and the inside air rapidly occurs, so that the occupants may feel rejected for ventilation.

In order to solve the above problems, Korean Patent Publication No. 10-1818434 describes a window system capable of ventilation even when the window is not opened. A window frame in which a chamber capable of accommodating air is formed is disposed, and an air inlet passage and an air outlet passage communicating with the chamber are formed to realize ventilation.

However, such a simple communication structure of a flow path may cause a problem in that the efficiency in which indoor air is discharged to the outdoors is inferior.

Korean Patent Publication No. 10-1818434 "Window-type ventilation device and automatic window ventilation system using the same" (2018. 01. 09.)

The present invention was conceived to solve the above problems, and an object thereof is to provide a system window capable of maximizing ventilation efficiency and performing a crime prevention function.

The present invention relates to a system window installed on a building wall, the inner frame in which the edge of the window is installed at a predetermined depth, the outer frame formed on the outer periphery of the inner frame, and the plurality of frames are combined with the inner surfaces of the plurality of frames, and are disposed opposite to each other to the outside of the building And a plurality of spacers that block internal heat exchange, wherein the plurality of frames are opened and closed by selectively contacting the inner frame by moving in the thickness direction, and a hollow part is formed between the plurality of frames, the When both sides in the thickness direction of the plurality of frames are not in contact, outside air is introduced into the building, and the spacer is interposed in a plurality of the hollow part, and the hollow part is opened and closed depending on the movement of the outer frame or the inner frame. When the hollow part is opened, the outdoor side of the flow path formed by the plurality of spacers is formed in a bell mouse shape.

In addition, the flow path of the air formed by the plurality of spacers depending on the movement of the outer frame or the inner frame is a bell-mouse-shaped suction unit that easily sucks outside air, and a flow velocity that increases the flow velocity of the outside air sucked from the suction unit. It is characterized in that it is formed sequentially from the outdoor side to the indoor side, including an acceleration part and a discharge part for discharging the sucked outdoor air by forming a low pressure.

In addition, when the hollow portion is opened, the flow velocity acceleration unit is formed with a first cross-sectional area of a section communicating with the suction unit to a value greater than a second cross-sectional area of the section communicating with the discharge unit, and the discharge unit at the side of the suction unit It is characterized in that the cross-sectional area continuously decreases toward the side to increase the flow velocity of the outside air.

In addition, the discharge portion is characterized in that the cross-sectional area continuously increases from the outdoor side to the indoor side, and the pressure decreases along the traveling direction of the outside air.

In addition, the spacer includes a bottom portion coupled to the plurality of frames, and a floor consisting of the largest distance between the bottom portion, and further includes a corner portion forming an inflow path of the outside air, and the corner portion comprises the floor portion. As a reference, the curvature value of the indoor side is greater than the curvature value of the outdoor side.

Due to the present invention, it is possible to improve the ventilation efficiency of a system window that does not open many windows.

Accordingly, it is possible to prevent the inflow of foreign substances such as rainwater during ventilation, and the security function can be performed at the same time.

Terms and words used in this specification and claims should not be construed as being limited to their usual or dictionary meanings, and that the inventor can appropriately define the concept of terms in order to describe his own invention in the best way. Based on the principle, it should be interpreted as a meaning and concept consistent with the technical idea of the present invention.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all the technical spirit of the present invention, and various equivalents that can replace them at the time of application And it should be understood that there may be variations.

Hereinafter, prior to the description with reference to the drawings, matters that are not necessary to reveal the gist of the present invention, that is, known configurations that can be obviously added by those skilled in the art are not shown or described in detail. Make sure you didn't.

1 is an exemplary view showing a system security window with improved ventilation efficiency according to the present invention. System windows can be made of various structures according to the opening and closing method, and can be classified into Tilt & Turn, Tilt only, Fix, and Tilt & Slide. Among the above-described methods, the ventilation mode shown in Fig. 1(c) is realized in a plurality of system window types excluding the Fix type. That is, the inner frame 200 moves at a predetermined interval based on the outer frame 100 fixedly installed on the building wall as shown in (b) of FIG. 1, so that outside air may be introduced into the room or the inside air may be discharged to the outside. Create a flow path. In the ventilation mode, there is an advantage in that it is possible to prevent other foreign substances from entering because only a flow path for circulation of outside air and inside air is formed.

As shown in FIG. 1, the present invention relates to a system window installed on a wall of a building, and includes an outer frame 100 and an inner frame 200 in which a glass window is installed. The outer frame 100 is fixed and disposed on the wall of a building, and the inner frame 200 has a structure capable of moving at predetermined intervals in the thickness direction (transverse direction) of the frame according to the user's selection.

2 is a cross-sectional view showing a system security window with improved ventilation efficiency according to the present invention. As shown in FIG. 2, between the plurality of frames 100 and 200, a hollow part 400 through which outside air and inside air of a building wall enters and exits is formed.

For detailed description, one side (indoor side) in the thickness direction of the outer frame 100 is defined as a first outer frame end 110 and the other side in the thickness direction (outdoor side) is defined as a second outer frame end 120. In addition, one side in the thickness direction (indoor side) of the inner frame 200 is defined as a first inner frame end 210, and the other side in the thickness direction (outside side) is defined as a second inner frame end 220.

The hollow part 400 has the first outer frame end 110 and the first inner frame end 210 in contact with each other, and the second outer frame end 120 and the second When the inner frame ends 220 are in contact with each other, they are closed.

When a resident of a building needs ventilation and moves the inner frame 200 at a predetermined interval, an inlet and an outlet of outside air are formed between the ends of the plurality of frames as shown in FIG. 2A. That is, the hollow part 400 is opened to create a path through which outside air is introduced. Existing bet is circulated inside according to convection and is discharged to the upper side of the system window.

Accordingly, the hollow part 400 is opened or closed depending on whether the inner frame 200 is moved, so that a resident of the building can selectively perform ventilation.

A plurality of spacers 300 coupled to the plurality of frames 100 and 200 may be disposed in the hollow part 400 to improve the efficiency of introducing outside air into the room, and related shapes and structures will be described later.

3 is an enlarged view showing the opened hollow part 400 according to the present invention. The hollow part 400 is divided into a plurality of sections by the plurality of spacers 300. A suction unit 410, a flow velocity acceleration unit 420, and a discharge unit 430 are sequentially divided and partitioned from the outdoor side to the indoor side along the thickness direction of the plurality of frames 100 and 200.

The suction unit 410 is a section in which the external air introduced from the outdoor side collides with the plurality of spacers 300 for the first time, and has a bell mouse shape in which the cross-sectional area of the flow path gradually decreases along the direction in which the outside air flows into the interior I can. The structure as described above reduces the eddy current of the incoming outdoor air and is converted to a lateral flow, so that the outside air can be easily introduced.

The flow velocity accelerating unit 420 is a section in which the velocity of the external air introduced from the suction unit 410 increases, and may have a structure in which a cross-sectional area gradually decreases along an inflow direction of the external air. That is, the value of the first cross-sectional area A1 communicating with the suction unit 410 is larger than the value of the second cross-sectional area A2 communicating with the discharge unit 430.

This means that if the flow rate in the first cross-sectional area (A1) and the second cross-sectional area (A2) is constant according to the flow rate equation, the flow rate gradually increases when the outside air that minimizes the loss of flow rate by the bell mouse-shaped suction unit 410 Means to do.

In other words,

According to the above equation, the inflow rate of outside air is continuously increased.

The discharge part 430 is a section in which low pressure is formed, and external air may be easily introduced due to a pressure difference. In this case, the cross-sectional area of the discharge unit 430 may be configured to increase continuously along the inflow direction of the outside air, unlike the suction unit 410 and the flow velocity acceleration unit 420.

The pressure of the discharge unit 430 is lowered according to Bernoulli's theorem that the velocity and pressure are inversely proportional to the outside air in which the flow velocity is increased in the flow velocity acceleration unit 420. Accordingly, the inflow efficiency of the outside air introduced from the flow rate accelerating unit 420 may be maximized.

4 is an exemplary view showing a spacer 300 according to the present invention. As shown in FIG. 4, the spacer 300 may be formed of an arc having a specific curvature at a corner portion to form a special shape of the hollow portion 400 shown in FIG. 3. For a detailed description of the spacer 300, a surface in contact with the outer frame 100 or the inner frame 200 to be combined is the bottom surface 310, the bottom surface 310 and the most The far away point is defined as the floor 320.

The floor 320 is formed at a point deviated from the midpoint of the bottom portion 310. This is to design the flow path of the hollow portion 400 formed by facing the plurality of spacers 300 in the shape shown in FIG. 3. That is, the curvature of the section forming the suction part 410 and the flow velocity accelerating part 420 is made softer than the curvature of the section forming the discharge part 430, and the discharge part 430 of the hollow part 400 ), the pressure can be designed in an effective structure.

In addition, the curvature of both sides of the spacer 300 in the longitudinal direction of the spacer 300 is made of different values from the floor 320 of the spacer 300, and the plurality of spacers 300 are arranged opposite to each other, so that the suction unit 410, a flow velocity accelerating unit 420 and a discharge unit 430 are generated.

In a state in which the hollow part 400 is closed, the plurality of spacers 300 coupled to the plurality of frames 100 and 200 and disposed opposite to each other block the flow path by contacting the plurality of floors 320. In order to realize the structure as described above, the spacer 300 may be formed of a separate hollow layer 330, and the plurality of spacer 300 may be in contact with each other to change a shape within a certain range. However, if the hollow part 400 is formed of a material capable of easily blocking the flow path in the closed state or a structure capable of realizing this, the structure of the spacer 300 is not separately limited.

5 is an exemplary view showing a flow path formed by a plurality of spacers according to the present invention. As shown in FIG. 5, the plurality of spacers 300 are disposed to face each other in the plurality of frames 100 and 200 to form a flow path through which outside air is introduced. In this case, the shape of the external air inflow passage formed in the hollow part 400 varies according to the range in which the inner frame 200 moves. That is, as shown in (a), if the movement range of the inner frame 200 is extremely limited to less than 5 millimeters (mm), a flow path having a sufficient distance through which outside air can be introduced is not formed. In addition, as shown in (c), if the movement range of the inner frame 200 is made to be an excessively large value of 8 millimeters (mm) or more, foreign substances other than outside air may be introduced into the frame, resulting in a decrease in ventilation efficiency. .

(b) is an exemplary view showing a state in which the first inner frame end 210 of the inner frame 200 is moved by a predetermined distance from a point in contact with the first outer frame end 110. At this time, the flow path of the outside air formed by the plurality of spacers 300 is a value in which the suction part 410 in the shape of a bell mouse is most ideally formed, and the subject of the present invention can be effectively solved.
