DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an automatic ventilation apparatus for a sliding window according to the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the sliding window 1 is a window 2 opened and closed while sliding along the rail 4 of the rail frame 3, and a plurality of rails 4 are provided on the bottom surface of the rail frame. And a groove 5 is formed between front and rear portions at predetermined intervals.

Although the automatic ventilation device is described as being coupled to the lower end of the window for the purpose of helping understanding of the present invention, it is only an example for explaining the present invention, It can be installed at the bottom or at the top of the door.

FIG. 1 is a view showing an automatic ventilation apparatus for a sliding window according to an embodiment of the present invention, and FIG. 2 is an exemplary view showing a state where the automatic ventilation apparatus shown in FIG. 1 is mounted on a window.

1 and 2, the automatic ventilation device of the sliding window includes a fixed block 10, a driving motor 20, a first wheel 30 and a second wheel 40. [

The fixed block 10 is a block having a predetermined thickness fixed to the lower end of the window, and is fixed to the outer circumferential surface of the window through an adhesive or tape having excellent adhesive strength.

The fixed block 10 is formed with a motor insertion groove 11 into which the driving motor 20 is inserted and a wheel insertion groove 12 into which the first wheel 30 is inserted.

The drive motor 20 is a motor capable of rotating in forward and reverse directions, and a worm 21 is formed in a spiral shape along the outer peripheral surface of the rotary shaft.

The first wheel (30) is rotatably inserted into the wheel insertion groove (12).

The first wheel 30 is connected to the rotation shaft of the driving motor 20 and rotates through a rotational force of the driving motor. The worm wheel 31 is engaged with the worm 21 at one end of the first wheel 30 and the other end is protruded outward from the fixed block by a predetermined length.

The present invention can increase the power of the driving motor 20 through the worm 21 and the worm wheel 31, so that heavy or large windows can be smoothly opened and closed.

The second wheel 40 is fitted on the outer circumferential surface of the first wheel 30. The outer circumferential surface of the second wheel 40 is connected to a guide rail provided on the bottom surface of the groove 5 between the rail and the rail provided on the rail frame 3 50). The second wheel 40 rotates together with the first wheel 30 rotating through the rotational force of the driving motor 20 and rolls along the guide rail 50 to open and close the window.

On the other hand, when the automatic ventilation device is installed in the window with the window closed, the window can be opened through the driving motor only when the locking device of the window is released. However, if the locking device of the window is released, the window can be easily opened from the outside and can enter into the room.

In order to solve such a problem, the second wheel 40 according to the present invention is made up of a pinion gear, and the guide rail 50 is made up of a rack having a predetermined length meshed with the pinion gear.

Since the teeth of the pinion gear are engaged with the teeth of the rack when the drive motor 20 is stopped, it is impossible to open the window arbitrarily even if the force is applied to the window from the outside.

In addition, when the drive motor 20 rotates, the teeth of the pinion gear move while meshing with the teeth of the rack, so that slipping of the second wheel 40 can be prevented, and power loss of the drive motor can be reduced have.

Next, referring to FIG. 3, the present invention further includes a clearance blocking member 60 for blocking clearance between the window and the rail frame to prevent forcible opening of the window.
