Description

Automatic opening and closing ventilation windows

The present invention relates to a system window that is being used for apartment balconies, windows, windows of homes and villas, and windows, more specifically, one of which is opened at a predetermined tilt during indoor exhaust and ventilation. It relates to an automatic opening and closing device of a ventilation window that enables a closing window to be automatically opened and closed by a carbon dioxide detector and at the same time an artificial automatic opening and closing through a remote control and a switch operation by a remote controller.

In general, in the system window, the window for the exhaust and ventilation is largely divided into a tilt function window and a swing function window. In particular, the tilt function window is one of the windows (upper, lower, Left and right) is a structure that opens and closes at a predetermined inclination (about 10 ° to 15 °), and is widely used in current system windows due to the fact that it can effectively prevent sudden changes in indoor temperature, theft during going out, and sleeping. It's happening.

However, the conventional tilt function of the ventilation window is a structure in which the occupants manually hold the handles installed on the window and manually open or close the window when the room is exhausted and ventilated. There are many problems, such as the difficulty of manual operation of the handle, especially for the disabled or the elderly or children, and the possibility of physical damage such as the finger being pinched due to carelessness during opening and closing of the ventilation window. It is inherent.

In addition, although the structure of opening and closing the ventilation window through the artificial manipulation of the switch attached to the conventional window frame is known in part, this also has a structural problem that the movement of the occupant for the switch operation is inevitable.

On the other hand, according to Utility Model Registration No. 304347, which is filed in advance by the applicant of the present application to solve the problems of the conventional manual method and the switch operation method, the user can remotely control the projection window by using a remote control for more convenience of use. Although the automatic window opening and closing of the projection window is increased, in this case, since the projection window is made only by artificial remote control of the occupants, there is a problem that proper indoor / outdoor ventilation and ventilation cannot be performed during bedtime at night as well as at night. .

For example, when sleeping at night, due to various concerns such as theft, various windows are normally closed and completely closed to prevent proper ventilation inside and outside the room, and the amount of carbon dioxide generated during breathing also increases naturally, which is necessary for a good night's sleep. The smooth circulation of air is not achieved. Therefore, the sleeper may not be able to get a stable and comfortable sleep due to lack of oxygen, and also cause a significant disadvantage in health through a decrease in body biorhythm or lack of sleep. In particular, this is becoming more and more problematic in that most of the living space of modern people is composed mainly of apartment living culture made of concrete.

Therefore, the present invention is to automatically detect the degree of indoor pollution, such as carbon dioxide, in order to automatically open and close the tilt function of the ventilation window in order to maintain a stable indoor environment through the appropriate indoor and outdoor ventilation automatically in view of the conventional problems. The purpose is to provide an automatic opening and closing device of the ventilation window.

Another object of the present invention is to provide an automatic opening and closing device of the ventilation window to enable the automatic opening and closing of the ventilation window by the remote control or switch operation by the remote control operation of the occupant in addition to the automatic opening and closing of the ventilation window by the detector.

It is assembly side section and flat section open state.

First, referring to FIGS. 8A and 8B, the switch 40 has the switch body 49 firmly mounted on the outdoor side of the fixed window frame 10 by a plurality of fixing screws, and the first and second lead screws. Folding member composed of a plurality of connecting rods 48-1, 48-2, and 48-3 between the lead screws 44-1 and 44-2 of the shafts 43-1 and 43-2. The hinge fixing block 45 to which the 48 is connected and supported is also firmly mounted and assembled by a plurality of fixing screws with respect to the window frame 20 of the ventilation window 2.

At this time, the hinge fixing guide block 45 attached to the window frame 20 of the ventilation window 2 is attached to the substantially center portion of the window frame 20 on the open / close end side.

In addition, the connecting rods 48-1, 48-2, and 48-3 of the folding member 48 have the first and second lead screw shafts 43-1 and 43-2 with the ventilation window 2 closed. Since the lead screw nuts 44-1 and 44-2 of the &quot;) are retracted and moved to both sides, they are kept in a contracted state.

In this state, when the carbon dioxide concentration by the carbon dioxide detector 30 installed in the room is detected above the set reference value, the corresponding signal is transmitted to the central controller 50, and the central controller 50 receiving the carbon dioxide detection signal is a switch. The drive signal is simultaneously sent to the first and second forward and reverse drive motors 41-1 and 41-2 of 40.

Therefore, the first and second forward and reverse driving motors 41-1 and 41-2, which are driven with the driving signal from the central controller 50, are rotated forward (for convenience of description, the direction in which the ventilation window 2 is opened is called forward rotation). The closed state is defined as reverse rotation, and at the same time, the first and second lead screw shafts 43-1 and 43-2 fastened thereto are also decelerated by the reduction gears 41-1a and 41-2a. Is rotated.

Each lead screw nut 44-1 provided on each of the lead screws 43-1a and 43-2a by the deceleration rotation of the first and second lead screw shafts 43-1 and 43-2 ( 44-2) are moved and retracted to the center of each other, and at the same time, the ends of the lead shaft nuts 44-1 and 44-2 are connected to the center shaft 47a by connecting rods 48-1. The connecting table 48-2 and the other connecting table 48-3, which are integrally fixed to the additional switch body 49, extend in a straight line as shown in FIGS. 9A and 9B while sequentially unfolding.

therefore. The hinge 46, which is disposed at the other end of the connecting rod 48-2 of the cutting member 48 extending in a straight line, is naturally formed of a plurality of connecting rods 48-1, 48-2, and 48-3. The ventilation window 2 which pushes the hinged fixing block 45 forward by the elongated length of the 48 and is fixed to the hinged fixing block 45 which is rotated with respect to the hinge 46 is the hinge member of the other side ( 3) The open end side is opened at a predetermined angle while drawing a constant arc around 3), and the venting and venting into and out of the room can be performed quickly and smoothly by the opening operation of the ventilation window 2.

On the other hand, when the ventilation window 2 is opened, the hinge fixing block 45 is freely rotated around the hinge 46 placed on the connecting table 48-3, so that the folding member 48 extends in a straight line. Even if it is possible to open the circular arc of the ventilation window (2), the hinge 46 is the hinge 46, because the flow preventing groove 46b is interlocked with the safety pin 45b of the hinge guide block 45 of the hinge 46 The left and right flows are prevented so that the stretchable operation of the stable connecting table 48 is possible.

And, even if the ventilation window 2 is not indoor ventilation by the first and second forward and backward driving motors 41-1 and 41-2 to which the automatic timer 90 is added, after a predetermined time has elapsed, FIG. 8. And through the stretching operation of the folding member 48 consisting of a plurality of connecting bars (48-1, 48-2, 48-3) that is folded operation as shown in Figure 9 through the repeated operation to automatically open and close the ventilation continuously Since it is possible to create a comfortable indoor environment at all times, in particular, such periodic indoor ventilation is automatically performed by detecting the carbon dioxide concentration of the carbon dioxide detector 30 even at bedtime, so that the optimal sleep state through the smooth supply of oxygen You can always keep.

On the other hand, as shown in Figure 7, the automatic opening and closing of the ventilation window 2 according to the present invention can be made by the control of the remote or manual switch operation by the remote control as well as the automatic control by the carbon dioxide sensor (30).

In addition to the carbon dioxide detector 30, the central controller 50 includes a signal receiver 72 for controlling a remote signal of the remote controller 70 and a manual switch signal controller 82 for controlling a signal of the manual switch 80. If you want to open and close the ventilation window 2 from time to time, as well as automatic opening and closing of the ventilation window (2) by detecting the carbon dioxide, as necessary, such as failure of the carbon dioxide detector (30), or the needs of the occupants. By remote control using the remote control 70, or by operating the manual switch 80 directly, it is possible to further increase the convenience of opening and closing operation of the ventilation window (2) in accordance with the indoor exhaust and ventilation.

According to the present invention as described above, the opening and closing of the ventilation window through the direct operation of the remote, manual switch by the carbon dioxide detector or the remote control is made automatically, it is possible to maintain a comfortable environment of the room and provide convenience of operation, especially at night As the ventilation of the room is periodically performed through the automatic opening and closing of the ventilation window at bedtime, the oxygen supply in the sealed indoor space is smoothly prevented and the lack of sleep due to lack of oxygen can be prevented. Not only that, but also contribute to the improvement of residential life through the supply of environmentally friendly products.
