The present invention relates to a window opening and closing device that can automatically open and close a window. More specifically, the present invention relates to a window opening and closing device that can automatically open or close a window by the operation of a remote control or button by installing an opening and closing device on the window, thereby allowing ventilation at a specific time. It is a window opening and closing device that allows you to control the opening and closing of windows using a home bus system or from the outside.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is an installation state diagram of the present invention, Figure 2 is a perspective view of the overall configuration of the present invention, Figures 3 and 4 are partial configuration diagrams of the present invention, and Figure 5 is an operation explanatory diagram of the present invention, according to the present invention. The window opening and closing device includes a window opening and closing device (100) that automatically opens and closes a window, a case (1) fixed to the frame of the window (10), and a motor ( 3), a worm (4) fixedly coupled to the motor shaft of the motor (3), a worm wheel (5) meshed with the worm (4) with a gear, and a worm wheel fixed to the worm wheel (5) It is characterized by being composed of a shaft (6) and a driving roller (7) fixed to the worm wheel shaft (6) and moved along the window frame (20).

First, the case 1 is fixed to the frame of the window 10 with screws, etc., and the cover 2 is detachable for the protection and aesthetics of the components stored inside the case 1.

Inside the case 1, a motor 3 that generates driving power to open and close the window by electric power is stored in a motor housing, and a worm 4 is fixedly coupled to the motor shaft of the motor 3, and the A worm wheel (5) is meshed with the worm (4) with a gear.

A worm wheel shaft (6) is fixedly coupled to the worm wheel (5), and a drive roller (7) is rotatably coupled to the case (1) on one side of the worm wheel shaft (6).

Therefore, when power is applied to the motor 3, the rotational power generated by the motor 3 rotates the worm 4, and the worm wheel 5 is rotated by the rotation of the worm 4, thereby rotating the worm wheel shaft 6. ) and the driving roller 7 are rotated to open or close the window 10.

The worm 4 and worm wheel 5 can achieve a higher reduction ratio than that of a typical gear, thereby reducing the capacity of the motor 3 required to move the window 10 and reducing battery consumption.

In addition, the case 1 is fixed to the upper frame 11 of the window 10, so that the load of the window 10 is not directly applied to the driving roller 7, thereby providing the power necessary to rotate the driving roller 7. It can be reduced.

In other words, in the case of a typical window opening and closing device, a driving roller is installed at the bottom of the window. When the driving roller is installed at the bottom of the window, the load of the window is directly transmitted to the driving roller, thereby relatively increasing the capacity of the motor and thus increasing the manufacturing cost. The size of the opening and closing device becomes relatively large, but in the case of the present invention, the case 1 is fixed to the upper frame 11 of the window 10, and the driving roller 7 is rotatable in the case 1. Because it is combined, the load of the window 10 is not directly transmitted to the driving roller 7, thereby reducing the power required to open and close the window 10.

In addition, the driving roller 7 is rotated in contact with the window frame 21, and the external roller portion 7a is in close contact with the side of the window frame 21 and the cross section of the window frame 21. It is composed of an inner roller part 7b, and the inner roller part 7b is formed with a groove part 7c whose shape corresponds to the protrusion of the window frame 21.

That is, the outer roller part (7a) of the driving roller (7) is completely adhered to the side of the window frame (21), and as a result, when the driving roller (7) is rotated, the driving roller (7) and the window frame (21) The opening and closing operation of the window 10 can be performed smoothly as no slip occurs between the windows 10, and the drive roller 7 is connected to the window frame 21 due to the groove portion 7c formed in the inner roller portion 7b. When moving along, it does not deviate from the path.

In particular, the distance between the outer roller parts 7a is shorter than the width of the window frame 21 in the absence of external force. Therefore, when the external roller part 7a is inserted into the window frame 21, its elasticity is reduced. It comes into close contact with the side of the window frame 21. Referring to FIG. 5, the external roller part 7a is inserted into the window frame 21 by its own elasticity and applies force from both sides in the direction of the arrow. The external roller unit 7a and the window frame 21 remain in close contact while the driving roller 7 moves along the window frame 21.

In addition, a battery (not shown) for driving the motor 3 is installed in the case 1, and the battery is connected to a terminal 8 installed outside the case 1 with a wire, and the terminal ( 8) When it comes into contact with a plug (not shown) installed on the window frame 20, electricity flows toward the battery and the battery is charged.

That is, the battery for driving the motor 3 can be a disposable battery, but instead of a disposable battery, a rechargeable battery is used and connected to the terminal 8 installed outside the case with a wire, and then the terminal 8 and the window frame 20 ) When the plug installed in the battery is touched, electricity can flow and the battery can be charged, and this method can be used semi-permanently without replacing the battery.

In addition, a controller is installed in the case 1 to control the movement amount and speed of the window 10, and the controller performs the opening and closing operation while maintaining the speed when the window 10 is opened or closed. While giving a command to perform, when the window 10 approaches the maximum open or closed position, the amount of power applied to the motor 3 is reduced to adjust the opening and closing speed of the window 10, and the window 10 is opened and closed. The moving distance is calculated by checking whether the window 10 is maximally open or maximally closed.

The controller further includes a communication device to open and close the window by receiving a user's command through a remote control or a switch attached around the window. When an open command is received when the window is closed, the motor (3) is activated. Power is applied to open the window at a relatively high speed, and when the window 10 opens to a certain extent and hits the window frame 20, the speed is gradually lowered to prevent the window 10 from hitting the window frame 20. Even when the window 10 is closed from the open state, the window 10 is similarly decelerated.

At this time, the calculation of the distance at which the window 10 opens and closes is measured by measuring the distance from the completely closed state of the window 10 using the first window opening and closing device 100 until the window 10 is fully opened, and the distance measured in this way is The speed will be adjusted when opening and closing the window from next time, and the distance that the window opens and closes can be calculated by installing an encoder around the motor to measure the distance.
