Relates to a device.

In general, doors installed to enter and exit the building mainly use sliding doors, and windows mainly use sliding doors.

The sliding door is used as an entrance door for arranging a separate space required for the rotation of the door because the door rotates about the rotation axis in the opening process, but the sliding door is opened and closed in the horizontal direction so that the door is opened. It is widely used as a window because it does not require a separate space.

According to the present invention, the sliding door type window has at least two doors installed on the door frame so as to be cross-movable so that any one door can be completely opened or closed according to the user's intention, and the two doors are separated from each other in the middle of the door frame. It can also be opened by overlapping.

However, such windows are opened or closed when the user's intention is to ventilate the indoor air, when it rains or snows outside, when the outside air is heavily polluted for reasons such as yellow dust, etc. Since the closing is entirely done by the user, there is a problem in that the damage is caused if not properly handled.

In other words, according to the trend of encapsulation of indoor buildings due to noise and energy saving in the case of indoor air, the accumulation of indoor air pollution concentrations and the increase in the use of harmful gases, environmental hormones and household goods generated from various building materials, etc. Because of this, the risk to human health is increasing day by day, it is good to open a certain time to periodically ventilate, it is difficult for people in the room to open and close the window periodically to determine the pollution of the air There is this.

In addition, when the rain or snow comes in the open state of the window immediately close the window does not flow into the room, it is difficult to determine whether rainfall or snowfall or in the state of going out there is a problem that it is difficult to properly respond accordingly.

Accordingly, the present invention has been made in view of the problems of the prior art, the object of which is to automatically open and close the window according to the pollution of the air in the air to enable ventilation, when the rain or snow outside the window is open automatically It is to provide a window opening and closing device to prevent the rain or snow from entering the room by closing the window, and to enable the opening and closing operation of the window simply by a switch operation.

(Example)

Hereinafter, with reference to the accompanying drawings showing a preferred embodiment of the present invention described above in more detail.

1 and 2, the window opening and closing device according to the present invention, the first window 12 and the second window 14 is mounted on the door frame 10 in the transverse direction cross open and close the sliding window It is assumed that the first window 12 is fixed, and the second window 14 is automatically opened and closed. However, a window operating in a sliding form by using only one window is also applicable. Any statement made can be applied.

A sliding window composed of two windows is usually provided with two rails at the lower end of the door frame 10, and at each lower end of the first and second windows 12 and 14 moving laterally on the door frame 10. At least two pulleys are mounted to allow the rails to move smoothly with respect to the rail.

Of course, in addition to the first and second window (12, 14) in contact with the bottom of the door frame 10 as described above, there is also a way that the rail is installed on the top of the door frame and the pulley is installed on the top of the window, The manner in which the contact is made at the lower ends of the door frame 10 and the first and second windows 12 and 14 has been described as an embodiment.

In the case of sliding windows, the lower and lower middle portions of the lower and lower portions of the first and second windows 12 and 14 may be opened and closed due to the load of the windows themselves. You can open and close it.

Therefore, in the present invention, the opening and closing device is installed at the lower end of the second window 14, and in the case of the sliding door supported by the upper end of the door is opened and closed, it would be preferable to install in the upper end unlike the embodiment of the present invention.

A driving bolt 22 is installed side by side on the lower side of the second window 14 moving from the door frame 10 in the sliding window under the above conditions, and the driving bolt 22 is coupled to the motor 20 to rotate. do.

Here, the motor 20 is a motor capable of forward and reverse rotation, the screw formed in the drive bolt 22 is a square screw, the reason for forming the square screw will be described below.

In addition, a nut-type bracket 34 having a structure as shown in FIGS. 3A to 3C is also mounted on one side of the second window 14 at a position coupled to the driving bolt 22.

The nut bracket 34 has a cylindrical shape divided into two in the horizontal direction. One side of the lower supporter 34b constituting the lower portion is fixed to one side of the second window 14.

The lower supporter 34b is formed such that its inner diameter has the same inner diameter as the outer diameter of the driving bolt 22, and the screw is not formed so that screwing with the driving bolt 22 is not made.

This is of course supported because one end of the drive bolt 22 is connected to the motor 20, but the other side is intended to replace the other means because the supporting means is not provided. .

In the state where the nut bracket 34 is coupled to the drive bolt 22, the nut bracket 34 may be reciprocated according to the rotation of the drive bolt 22, but the nut bracket ( In the state where the upper nut 34a is separated from the driving bolt 22 by using the hinge portion 34c of the 34, only the lower supporter 34b without the threaded portion can support the driving bolt 22. Since only the mechanical coupling relationship between the driving bolt 22 and the nut bracket 34 is not achieved, only one end of the driving bolt 22 is supported by the lower supporter 34b to the driving bolt 22. With respect to the lower supporter 34b, the second window 14 may be freely opened and closed because the lower supporter 34b may freely move.

The reason why the screw formed on the drive bolt 22 and the upper nut 34a is a square screw is as follows.

If the threaded structure of the drive bolt 22 is formed in a triangle or a quadrangle when the drive bolt 22 is reciprocated by rotating the drive bolt 22, the rotational movement of the drive bolt 22 is linear. Since the loss of energy occurs in the process of conversion to motion, the structure of the thread is a square screw, and the nut-type bracket 34 is divided into two parts of the upper nut 34a and the lower supporter 34b. Since the screw is formed only in the upper nut 34a, the thread structure is preferably formed by a square screw.

As described above, the driving bolt 22 and the nut bracket 34 are configured, and when the motor 20 is rotated forward or reverse in the coupled state, the second window 14 is opened or closed.

In addition, since the driving bolt 22 and the nut bracket 34 are bolted to each other and the nut can be moved by the rotation of the bolt, the nut bracket 34 is rotated by rotating the driving bolt 22. Can be moved linearly, but the second window 14 to which the nut-type bracket 34 is mounted cannot be rotated because the nut-type bracket 34 cannot be linearly moved to rotate the drive bolt 22. It cannot be opened and closed by an external force other than the motor 20.

However, as described in the configuration of the nut bracket 34, when the upper nut 34a is separated from the lower supporter 34b around the hinge portion 34c, the driving bolt 22 is Since it is simply mounted on the lower supporter 34b, the second window 14 can be opened and closed.

Therefore, when the user wants to open and close the window manually, the upper nut 34a is rotated about the hinge portion 34c to release the screw from the driving bolt 22 as described above.

At this time, in order to ensure that the coupling between the upper nut (34a) and the lower supporter (34b) is made stable, although not shown in the figure coupled to each other by mounting the spring to the hinge portion (34c) coupled state It is good to maintain a stable, and to be able to maintain a stable state in the separated state.

As described above, in order to automatically open and close the second window 14 in a situation where an opening and closing device made of components such as a driving bolt 22, a nut bracket 34, and a motor 22 is installed, an open state or a closed state An open / close sensor is needed to detect the condition.

The opening and closing sensor applied to the embodiment of the present invention used a magnet 18 and the first and second Hall sensors 43 and 44.

That is, the magnet 18 is attached to one side of the second window 14, and the first and second hall sensors 43 are positioned at positions corresponding to the magnets in the state where the second window 14 is completely closed and opened. , 44, the first and second Hall sensors 43 and 44 detect the magnetic field of the magnet 18 when the magnet 18 moves in accordance with the opening and closing of the second window 14. Since the respective signals are output, it is possible to check whether the second window 14 is opened or closed.

The opening and closing sensor is installed in the second window 14 in addition to the magnetic field sensor as in the above embodiment, and installed by operating two limit switches on the door frame 10, or the door coupler 10, such as a photocoupler Two optical sensors may be installed to determine whether the second window 14 is opened or closed.

The motor 20 is configured to be controlled by the control unit 20 through the driving unit 50, the driving unit 50 is a kind of driver for supplying the power required for the operation of the motor 20.

The control unit 20 closes the second window 14 completely in order to implement a function of checking whether the second window 14 is opened or closed through the first and second hall sensors 43 and 44. Or the open state is determined using the first hall sensor 43 or the second hall sensor 44, and the determination of the open state of the second window 14 is performed by the first hall sensor 43. The determination is based on the detection, and the determination of the closed state is determined based on the detection of the open state by the second hall sensor 44.

In addition, when the second window 14 is opened or closed due to the interruption of power, the motor 20 may be rotated forward (when the rotation direction of the motor is set to forward rotation to open the second window). For example, the reverse rotation is set to close the second window, but in some cases, the reverse direction may be set and operated.) To close the second window 14 so that the first hall sensor 43 is completely closed. In order to detect the state by using the second window 14 or the opposite state, the second window 14 is completely opened by using the second hall sensor 44 by rotating the motor 20 in reverse. Detect.

In addition, the control unit 20 is installed in the indoor pollution sensor 41 for measuring the pollution degree of the indoor air, installed in the outdoors rain sensor 42 for detecting rain or snow, the motor 20 is determined By the opening switch 45 for generating an open signal for rotation, the closing switch 46 for generating a closing signal for reverse rotation of the motor 20, the opening switch 45 or the closing switch 46; A stop switch 47 for generating a stop signal for the second window 14 to stop at the current position while the second window 14 is opened or closed, and the second window 14 is opened or closed when the predetermined time is reached. The setting unit 48 which can set the opening time and the closing time for the connection is connected.

The pollution sensor 41 is a semiconductor sensor that detects an explosive gas or a hazardous gas by using a resistance change by an oxygen adsorption / desorption reaction of an oxide semiconductor, a temperature change and a resistance change characteristic by combustion of a reducing gas, or an explosive gas. Contact combustion sensor for detecting harmful gas, solid electrolyte sensor for measuring gas concentration such as oxygen or carbon dioxide using potential difference according to ion movement between sensing electrode and reference electrode, infrared wavelength and temperature change absorbed according to gas type Infrared sensor for detecting harmful gas, electrochemical sensor for detecting the presence of harmful gas using redox current in electrolyte solution and porous membrane can be used. In order to install and operate several of these sensors together It is right.

As described above, the controller to which various sensors and switches are connected operates as follows.

First, when an opening signal is input from the opening switch 45 while the second window 14 is closed, the magnet 18 attached to the second window 14 is detected by the second hall sensor 44. The motor 20 is rotated forward until it is opened, and when a close signal is input from the close switch 46, the motor 20 until the magnet 18 is detected by the first hall sensor 43. ) Is rotated by reverse rotation, and when the stop signal is input from the stop switch 47 while the second window 14 is opened or closed by the opening switch 45 or the closing switch 46, the motor 20 is closed. ) Stops the second window 14 at the current position.

In addition, the control unit 20 has a degree of pollution of the air measured by the pollution sensor 41 is higher than a preset reference value (a reference value of the pollutant to be detected separately for each type of sensor installed). If the window 14 is closed, the motor 20 is rotated forward to open the second window 14, and the rain or snow is discharged through the rainfall sensor 42 while the second window 14 is open. When detected, the motor 20 is rotated in reverse to close the second window 14.

When the opening time or closing time of the second window 14 set by the setting unit 48 is reached, the motor 20 is rotated forward or reverse to open or close the second window 14.

The present invention made as described above enables the opening and closing of the sliding window by a simple switch operation, while opening or closing at a predetermined time by the user while automatically opening and closing the window according to the indoor air pollution and the external weather. This gives you the convenience of window management.

In addition, the present invention can open and close the window by transmitting the rotational motion by the drive bolt to the nut bracket that linearly moves, but the nut bracket cannot be moved with respect to the drive bolt in a screwed state. The external force, that is, because the window can not be forcibly opened and closed outside the window provides an effect that can be secured.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and the general knowledge in the technical field to which the present invention pertains without departing from the spirit of the present invention. Various changes and modifications will be made by those who possess.
