First, looking at the background technology in FIGS. 5 to 7, the smart window is a window frame 10 installed in an opening on a wall of a building, a window 20 (window) installed to be movable along the window frame 10, and a window 20 a sensor 40 installed on the indoor side of the window frame 10 to detect indoor temperature and humidity, air conditions, etc., and a bi-directional drive unit according to the humidity value measured by the sensor 40 It includes a control unit 50 that opens and closes the window 20 by controlling power supply to the window 30 . To this end, technologies such as applications installed and controlled on mobile phones (smartphones), Internet of Things (IOT), and artificial intelligence (AI) are utilized through wired and wireless online technologies such as 5G technology, wi-fi, and NFC.

The sensor 40 accommodated in the window frame 10 so as not to be exposed to the outside is electrically connected to the controller 50 so as to transmit the measured temperature and humidity (temperature and humidity) values, and functions to measure the indoor air pollution state. includes

A shaft 31, a pair of rollers 32, a drum 33, a first motor 34 having a reducer, a first pulley ( 35), a first wire 36, a second motor 37 with a reducer, a second pulley 38, a second wire 39, and a bi-directional driving unit 30 composed of a drum bearing 90 do.

The shaft 31 fixed to the lower end of the window 20 rotatably supports a pair of rollers 32 and a drum 33 to generate a first motor 34, a first wire 36, and a second motor. (37) and the window 20 is moved through the power transmitted from the second wire (39).

A pair of rollers 32 rotatably connected to each shaft 31 move while rolling along the rail 60 formed inside the window frame 10 when the window 20 moves. On the other hand, the rail 60 is composed of a shape in which a groove is dug inside the window frame 10 so that the pair of rollers 32 can move along a straight line while rotating.

The drum 33 having the drum bearing 90 inside and connected to the shaft 31 is supported by the shaft 31 . The drum 33 moves linearly in the direction in which the window 20 is opened or closed. The drum 33 has a first groove 33a in which the first wire 36 is wound on the outer circumferential surface of the drum 33 so as to be connected to the first wire 36 and the second wire 39 so as to be wound or unwound; A second groove 33b around which the second wire 39 is wound is formed.

The first motor 34 accommodated inside the window frame 10 is not exposed to the outside. When the humidity value measured by the sensor 40 exceeds a predetermined value, the first motor 34 receives an electrical signal from the control unit 50 and generates a driving force to open the window 20 . The first pulley 35 is connected to the output shaft of the first motor 34, rotates by the driving force generated by the first motor 34, and transmits the driving force to the first wire 36 while driving the first wire 36. wind up One end of the first wire 36 is wound around the first pulley 35, and the other end is wound around the drum 33. At this time, the driving force generated by the first motor 34 is transmitted through the first pulley 35 and transmitted to the drum 33 and the shaft 31 .

A second motor 37 is accommodated inside the window frame 10 so as not to be exposed to the outside, and the second motor 37 transmits an electrical signal from the control unit 50 when the humidity value measured by the sensor 40 is below a predetermined value. and generates a driving force to close the window 20. The second pulley 38 is connected to the output shaft of the second motor 37, rotates by the driving force generated by the second motor 37, and transmits the driving force to the second wire 39 while driving the second wire 39. wind up One end of the second wire 39 is wound around the second pulley 38, and the other end is wound around the drum 33. At this time, the driving force generated by the second motor 37 is transmitted through the second pulley 38 and transmitted to the drum 33 and the shaft 31 .

The control unit 50 operates the first motor 34 to open the window 20 when the humidity value measured by the sensor 40 exceeds a predetermined value while being accommodated within the window frame 10 and not exposed to the outside. Control, and control the second motor 37 to close the window 20 when the measured humidity value is less than a predetermined value after measurement at a predetermined time interval. That is, when the humidity value measured by the sensor exceeds a predetermined value, the bi-directional driving unit may be controlled to open the window. The controller 50 uses a commonly used embedded software-based processing device and stores a predetermined humidity value that is a standard for operation of a driving function of a window in a manufacturing process.

Describing the driving process, the drum 33 coupled to the shaft 31 has a first wire 36 wound on an outer circumferential surface so that the first wire 36 and the second wire 39 can be independently wound. A groove 33a and a second groove 33b around which the second wire 39 is wound may be provided. A device including a drum bearing 90 for smooth fastening and rolling motion of a pair of rollers 32 and the shaft 31 may be used. A pair of rollers 32 are raised according to the rail 60 formed in the form of a groove inside the window frame 10 . The shaft 31 is coupled to the window 20 and moves the window 20 with driving force applied from the first motor 34 and the second motor 37 . A first wire 36 and a second wire 39 wound in different directions are connected to the drum 33 . At this time, the first wire 36 is connected to the first pulley 35, the first pulley 35 is connected to the first motor (34). In addition, the second wire 39 is connected to the second pulley 38, and the second pulley 38 is connected to the second motor 37.

The reason why the window 20 is opened is that the first motor 34 drives the first wire 36 around the first pulley 35 while the window 20 is closed, and at the same time the drum 33 At , the first wire 36 is unwound. Accordingly, the shaft 31 receives force in the opening direction, and the window 20 connected to the shaft 31 moves in the opening direction according to the rolling motion of the pair of rollers 32 . At this time, as the window 20 moves, the second wire 39 wound around the second pulley 38 is unwound. In the process of closing the window 20, the second motor 37 drives the second wire 39 around the second pulley 38 while the window 20 is open, and at the same time the drum 33 ), the second wire 39 is released. Accordingly, the shaft 31 receives force in the closing direction, and the window 20 connected to the shaft 31 moves in the closing direction according to the rolling motion of the pair of rollers 32 . At this time, as the window 20 moves, the first wire 36 wound around the first pulley 35 is unwound. In the case of using two motors, when one rotates, the other acts as a resistance to rotation, which can reduce efficiency.

Based on the above-described configuration and function, an embodiment of the present invention related to a smart and intelligent window (window) improved for cost reduction, function improvement, and installation space reduction is disclosed. See Figure 1 below for an example. For convenience of description herein, a pair of rollers 32 are referred to as a roller unit 320; drum 33 to drum unit 330; the first groove 33a as the forward drum groove portion 331; the second groove 33b to the reverse drum groove portion 332; the first pulley 35 as the driven pulley 350; first wire 36 to reverse wire 360; By combining the functions of the first motor 34 and the second motor 37 into a drive motor 370; second pulley 38 to drive pulley 380; second wire 39 to forward wire 390; Define terms and reference numerals. reverse and forward; clockwise and counterclockwise; one side and the other side; Expressions indicating directions or positions are relative to each other and can change depending on the viewpoint.

Here, when two motors, the first motor 34 and the second motor 37, are conventionally used, when one rotates, the other acts as a resistance to rotation, reducing energy efficiency and weakening the rotational force of the motor. Vibration, noise, etc. may occur, and side effects may occur, such as increase in manufacturing cost or disadvantageous maintenance, and space required for motor installation to be doubled. Therefore, the present invention adopts only one drive motor 370.

The shaft 31 is disposed between the driving pulley 380 and the driven pulley 350 and then fixed to the window. The roller unit 320 is rotatably coupled to the shaft 31 . The drum unit 330 is disposed between the roller units 320 and is rotatably coupled to the shaft 31 . The driving motor 370 is fixedly installed on the window frame to generate driving force for opening and closing (opening and closing) the window. The drive pulley 380 is fixed to the rotation shaft (output shaft) of the drive motor 370 and rotates. The driven pulley 350 is rotatably installed on the window frame. To this end, a rotation shaft of the driven pulley 350 is fixed to the window frame, and the driven pulley 350 is rotatably coupled to the rotation shaft.

Only one drive motor 370 is provided to drive the drive pulley 380, and a conventional drive method and configuration may be cited. Here, the driving motor 370 is provided to rotate in both directions, and through this, it is possible to switch between forward (c1) (clockwise in the drawing) or reverse (c2) (counterclockwise in the drawing) rotation as needed. It is controlled by the control unit 50 to open and close the window.

The driving pulley 380 includes a forward pulley 381 having the function of the conventional second pulley 38, and in addition, is configured (equipped) with the same (same) standard (external diameter size, etc.) as the forward pulley 381. It includes a reverse pulley 382 that is installed side by side (installed side by side) on the same rotation axis (coaxial) and rotates together as one body.

The configuration of the driven pulley 350 follows the configuration of the conventional first pulley 35, but does not receive power from the first motor 34 as in the prior art, and only straddles the reverse wire 360 to advance (move) ) It is installed by receiving a bearing to perform only the function of changing the direction.

The configuration of the roller unit 320 is disposed so as to roll on the rail 60 like a pair of rollers 32 in the related art, and rotates with the shaft 31 as a rotation axis.

The configuration of the drum unit 330 follows the configuration of the conventional drum 33, but freely rotates independently (from each other) with respect to the roller unit 320, and rotates with the shaft 31 as a rotation axis. In particular, the height of the lowest part (bottom) of the drum part 330 is higher than the imaginary line connecting the lowest part of the driving pulley 380 and the lowest part of the driven pulley 350 in a straight line (d1) (upward distance) float), and the spacing (d1) may be 3 mm or more in consideration of the winding thickness of the wire. With this configuration, a space is given to avoid contact between the bottom of the drum unit 330 and the reverse wire 360 so as not to interfere with its operation (movement). See Figures 2 to 4.

The roller unit 320 always maintains contact with the rail 60 . The drum unit 330 includes a forward drum groove portion 331 for fixing the forward wire 390 and a reverse drum groove portion 332 for fixing the reverse wire 360 .

By winding or unwinding the forward wire 390 several times around the forward drum groove 331, the initial length of the forward wire 390 is adjusted to the initial setting corresponding to the window distance of the window, and then, the wound state is fixed so that it is not unwound. .

In the reverse drum groove 332, the reverse wire 360 is wound or unwound several times to adjust the length of the reverse wire 360 to the initial setting corresponding to the length required for opening and closing the window distance of the window, and then the wound state is unwound. fasten so as not to fall A fixing method may be tying, knotting, or using a fixing member such as a clip.

The forward wire 390 follows the configuration of the conventional second wire 39, one end is fixed to the forward pulley 382 of the drive pulley 380, and then the body is wound, and the other end is the forward drum groove portion of the drum unit 330. It is fixed to 332, and connects the driving pulley 380 and the drum unit 330 to be constrained to each other.

As the drive pulley 380 driven by the drive motor 370 rotates in the forward direction c1, when the body of the forward wire 390 is wound around the drive pulley 380, the length of the unwound portion is reduced and the drum unit ( 330), in the drawing example, is pulled (pull, pulled) from left to right to guide the left and right movement (b1) of the window to which the drum unit 330 is fixed.

At this time, the drum part 330 follows the movement of the forward wire 390 without rotation (it is dragged), but the roller part 320 can roll independently to help the movement to be made without friction. Since the body portion of the forward wire 390 that transmits the pulling force spans (winds) from the top to the bottom of the driving pulley 380/direct pulley 382, it goes upward (toward the top) of the shaft 31 serving as the rotational axis. Rotational force (rotational power) is applied.

In the transmission of rotational force, it is common to use a member such as a relatively bulky and expensive timing belt to prevent rotational slip (slipping on a pulley and spinning), but the present invention occupies In order to reduce space and cost, low-volume and inexpensive (cheap) wire is used. At this time, to avoid rotational slip, the end (one or the other end) of the wire is fixed at all, and then the body can be wound or unwound. .

Reverse wire 360 is configured in a different way than before. After one end of the reverse wire 360 is fixed to the reverse pulley 381 of the drive pulley 380, the body is provided to be wound, and as the drive pulley 380 rotates in the reverse direction (c2), the drive pulley 380 When the body of the reverse wire 360 is wound, the length of the unwound portion is reduced, pulling the drum unit 330 to guide the movement of the fixed window.

At this time, the middle part of the body of the reverse wire 360 is wound around the driven pulley 350 that functions like a pulley (it does not matter if the reverse wire slips and rotates with respect to the driven pulley), in the example of the drawing, from left to right Left and right movement (b1`) changes direction and moves from right to left to right and left (b2).

Since the other end of the reverse wire 360 is fixed to the drum unit 330, the drum unit 330 is dragged and moved along with the left and right movement b2 of the reverse wire 360 (at this time, the drum unit does not rotate). The window also moves left and right (b2), and the roller unit 320 rotates in the reverse direction (c2) to perform a rolling motion so that the movement is smooth.

In this way, the driving pulley 380 and the drum unit 330 are restrainedly connected (constrainedly connected) by the reverse wire 360, and the reverse direction (c2) of the driving pulley 380 driven by the driving motor 370 ( Counterclockwise) rotational force (rotational power) is transmitted to the drum unit 330 via the driven pulley 350 to open and close the window.

In summary, the reverse wire 360 that transmits the pulling force is connected (connected) from the bottom of the driving pulley 380/reverse pulley 381 to the bottom of the driven pulley 350, and winds around the driven pulley 350. It is configured to be fixed to the drum part 330 / forward drum groove part 332 after the direction is changed so that it returns to the upper part (over).

That is, the body portion that is wound or unwound to transmit force in the reverse wire 360 is located below the rotational axis of the driving pulley 380, spans from the bottom to the top of the rotational axis of the driven pulley 350, and the drum unit 330 It is fixed to and the final force is transmitted.

2 illustrates the arrangement of a configuration in which both the forward wire 390 and the reverse wire 360 are mounted, from the side. 3 shows that the rotational force of the driving pulley 380 in the forward direction (c1) pulls the drum unit 330 through the forward wire 390, and as a result, the roller unit 320 rolls in the forward direction (c1). This shows the state in which the window is opened (or closed) as the drum unit 330 moves in the left and right direction (b1).

In the reverse closing (or opening) process, when the reverse direction (c2) rotation of the drive pulley 380 occurs, as shown in the example of FIG. It is made by moving away from the pulley 380 in the right-left direction (b2). At this time, contrary to the above, the forward wire 390 is released from the driving pulley 380 in response to the movement in the right-left direction (b2) and returns to the original (unwound) body lengthened state. Reference is made in combination to the examples of FIGS. 3 and 4 showing operating states in isolation.

On the other hand, the longitudinal wire 390 and the reverse wire 360 may be configured so that the speed at which the drum unit 330 pulls and pulls and the speed at which the drive pulley 360 is released is synchronized (synchronized).

The rotational force of the driving pulley 380 in the reverse direction (c2) is changed in direction and transmitted by the driven pulley 350 wound around the reverse wire 360, and finally pulls the drum unit 330 and moves in the right and left direction (b2). The window closes (or opens).

On the other hand, the process of opening (or closing) the window is performed while the drive pulley 360 rotates in the forward direction (c1) as before, and at this time, the body of the reverse wire 360 wound around the drive pulley 360 is Corresponding to the horizontal movement (b1) of the part 330, it returns to its original state before winding while being unwound.
