In addition, the drive motor 40 may be disposed vertically inside the space so that the rotation shaft may penetrate to the outside of the window frame, and the size of the drive motor may increase when it is installed on a window provided with a heavy or large window. .

In this case, as shown in FIG. 1, a drive motor 40 is disposed in the space portion along the longitudinal direction, and a rotation shaft of the drive motor is connected to a drive shaft (not shown), and a driven shaft perpendicularly crossing the drive shaft is the window frame. A gearbox 42 protruding outward from the lower portion may be provided inside the space. Reference numeral 41 in FIG. 1 is a driven shaft of a gearbox that transmits rotational force of a driving motor to an opening/closing link.

In addition, the drive motor 40 is preferably a geared motor.

For example, it is desirable to reduce the rotational speed of the drive motor because a user who has a low user's wits, such as a child or the elderly, opens and closes a window quickly, and a hand or foot may get caught in the window frame and cause injury. When the power of the driving motor is large or heavy, it is necessary to increase the power of the driving motor, so by configuring the driving motor 40 as a geared motor to lower the speed of the opening/closing link 50, which will be described later, a safety accident can be prevented. It is desirable to allow opening and closing without being affected by the size or weight of.

Next, the opening/closing link 50 has one end coupled to the rotation shaft of the drive motor (or the driven shaft of the gearbox) and the other end is hinged with the moving piece 20 so that one side of the driving motor 40 is rotated. Alternatively, while rotating to the other side, the moving piece 20 hinged to the end is moved inside the guide groove 10, and the moving piece 20 is moved along the guide groove 10 while pushing or pulling the window It opens or closes automatically as the force acts.

Here, the wireless controller may be a device that simply drives a driving motor in a place where a window is installed, such as a remote control in a narrow range, or from the outside based on the Internet of Things (IOT) when viewed from a wide range. It may be an electronic device (eg, a smartphone or a laptop capable of wireless Internet) that can open or close a window by controlling a driving motor. When the driving motor is controlled based on the Internet of Things, forced manual switching or automatic locking is possible, thereby preventing crimes caused by external intrusion.

Next, the present invention includes a connection arm 60 that supports the opening and closing of the window more smoothly in the lower part of the window.

2 and 3 are schematic illustrations showing the connection arm 60 according to the present invention, a window frame fixing bracket 61 fixed to the lower upper surface of the window frame 1 and a window frame fixed to the bottom of the window Bracket 62, a first rotation link 63 hinged at both ends to one end of the window frame fixing bracket and one end of the window frame fixing bracket, and the other end of the window frame fixing bracket and the bottom of the window frame fixing bracket Both ends are hinged to the central portion and includes a second rotation link 64 formed longer than the first rotation link.

When the window 2 is closed, the connecting arm 60 is in a straight line as the first rotation link 63 and the second rotation link 64 are folded between the window frame fixing bracket 61 and the window frame fixing bracket 62. When the window 2 is opened, the first rotation link 63 and the second rotation link 64 are unfolded with respect to the window frame fixing bracket 61 and the window frame fixing bracket 62 as shown in FIGS. 2 and 3.

It may include an auxiliary link 65 that is hinged to the window frame fixing bracket 61 and the other end is hinged to the center of the second rotation link 64 adjacent to it.

In addition, limit sensors 70 for detecting a position at which the moving piece is moved may be mounted at both ends of the guide groove 10. The limit sensor 70 interlocks with the driving motor 40 and outputs a signal when it is touched by the moving piece 20 so that the power of the driving motor is immediately cut off through the control unit, thereby preventing over-rotation of the driving motor 40. Prevents, and through this, it is possible to secure the durability of the moving piece 20 and the opening and closing link 50.

In addition, the present invention includes a temperature sensor for sensing external temperature on the window frame, a humidity sensor for sensing humidity, an illuminance sensor for recognizing light or detecting the amount of light, and for detecting smoke or flame generated in a fire. One or more of a fire detection sensor, an air pollution detection sensor that detects the degree of pollution in the atmosphere, and a gas sensor that detects the leakage of a specific gas are installed, but it is automatically opened and closed according to the operation of the sensor by interlocking with the motor. It is possible to set the operating condition or control the operation of the sensors through the control unit.

For example, when a fire occurs outdoors while a fire detection sensor (not shown) transmitted and received with the control unit is installed on the outer peripheral surface of the window frame, the control unit operates the driving motor 40 through a signal output from the fire detection sensor. To protect the room from fire by automatically closing the window.
