BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic window opening /

The present invention relates to an automatic window opening and closing apparatus having a switch that can be easily opened and closed. More specifically, the present invention relates to an automatic window opening / closing apparatus for an automatic window opening / closing apparatus having a switch for detecting opening / ≪ / RTI >

When a fire occurs in an apartment, a high-rise building, or a factory, a large amount of smoke is generated due to combustion of indoor furniture or interior materials. Because smoke contains toxic gases, most of the personal injury caused by fire is caused by smoky smokes including toxic gas rather than heat.

That is, when a fire occurs, smoke containing a large amount of toxic gas is instantly generated, and this toxic smoke is leaked to the evacuation route, making it difficult to evacuate through the evacuation route, resulting in many casualties, It can cause a serious problem to the rescue work.

Therefore, in the apartment and the like, the smokestack area (all rooms) is arranged according to the relevant regulations so as to prevent the smoke generated in the fire from spreading to the whole building.

Normally, when a fire occurs, the doors and windows of the ventilation area are automatically closed. In addition, outside air is introduced into the ventilation area to increase the air pressure in the ventilation area rather than the air pressure in the fire area. Thus, it is possible to prevent a toxic gas including smoke from flowing into the smoke-inducing section, thereby securing an evacuation route or passage.

A window opening / closing device for normally opening and closing a window so as to open and close the outside and the smoke-free area so as to maintain the function of the smoke-free area and to block the outside and the smoke-free area when the fire is closed; An emergency supply unit that opens the passageway and raises the internal pressure of the ventilation zone, an emergency door provided between each household and the evacuation step, and a control unit for automatically controlling the operation of such various devices or mechanisms.

With this configuration, when a fire is detected by a sensor or the like in any one of the households such as an apartment, the control unit closes the window and supplies outside air through the air supply unit to raise the internal pressure in the smoke- The door is closed to control the entire room formed between the fire occurrence area and the evacuation step to maintain the function of the smoke extraction area.

That is, when a fire occurs in the indoor space, the ventilation zone is formed in a closed state, and the internal pressure of the ventilation zone is raised to a certain pressure (for example, 40 Pa to 60 Pa) or more by the air supply action of the air supply unit. Accordingly, it is possible to prevent the toxic gas generated by the occurrence of the fire in the indoor space from entering the smokestacking area and the evacuation step.

The closing sensing member 185 and the opening sensing member 175 are respectively connected to the chain case 155 and are provided with a closing and opening indication attached to the chain 151 guided along the chain guide 157 inside the chain case 155 Members 183 and 173, respectively.

The closing and opening sensing members 185 and 175 have the same structure and have different positions sensing the chain 151 as shown in FIG. 3, FIG. 5A, and FIG. 5B, It is different.

The closing and opening sensing members 185 and 175 are structured as shown in Fig. The closing and opening sensing members 185 and 175 include a hall sensor that senses the sensed signal and the closed and open connection terminals 185d and 175d to which power is supplied and the closing and opening indicating members 183 and 173 Closing and opening sensors 185h and 175h which are electrically connected to the sensors 185h and 175h and closed and open substrates 185f and 175f which are electrically connected to the sensors 185h and 175h and the sensors 185h and 175h, Closing openings 185a and 175a formed so as to be supported by the chain case 155 and mounting parts (not shown) for controlling the electric circuits and sensors 185h and 175h circuits.

That is, when the closing and opening indicating members 183 and 173 are located at the lower center of the closing and opening sensors 185h and 175h, the closing and opening sensors 185h and 175h are set to the closest It is possible to sense the open position and the closed position of the chain 151 by sensing strong magnetic force.

The operation of the window opening / closing apparatus 100 according to one embodiment of the present invention having such a configuration will be described with reference to FIGS. 5A and 5B.

When the power is externally applied and the window opening / closing apparatus 100 is automatically closed by a control unit (not shown), the motor 123 is driven to rotate the speed reducer 125, the power transmission module 130, and the sprocket 153 ) -Chain 151 in this order, so that the motor 123 rotates so that the chain 151 enters the inside of the chain case 155. In this case, The chain 151 is moved inward along the chain guide 157 and the window 11 is gradually closed so that the closing indicating member 183 attached to the front attachment 151a is closed with the closing detecting member 185 The sensor 185h senses that the window 11 has reached the closed position and sends the sensed signal to the control unit. Based on the signal detected by the closing detection member 185, the control unit controls the motor 123 to stop the rotation. Thus, the window 11 can automatically be kept closed at the closed position.

On the other hand, when power is externally supplied and the window opening / closing apparatus 100 is automatically opened in the control unit (not shown), the motor 123 is driven to rotate the speed reducer 125, the power transmission module 130, The power is transmitted in the order of the chain 151 and the chain 151, and the motor 123 rotates so that the chain 151 goes out of the chain case 155. The chain 151 is moved outward along the chain guide 157 and the window 11 is slowly opened so that the opening indicator member 173 attached to the rear attachment 151b is moved to the opening of the opening sensing member 175 Upon detection by the open sensor 175h, it senses that the window 11 has reached the open position and sends the sensed signal to the control unit. Based on the signal detected by the opening sensing member 175, the control unit controls the motor 123 to stop the rotation. Thus, the window 11 can be automatically kept open at the open position.

Although the closed and open sensors 185h and 175h and the closing and indicating members 183 and 173 according to the embodiment of the present invention use a Hall sensor and a magnet respectively, Method can be changed.

Differences between the present invention and the prior art will be described in detail with reference to FIGS. 6A and 6B.

6B is a schematic view illustrating a state in which the window 11 is closed at the closed position in the window opening / closing apparatus 200 according to the related art.

For the sake of convenience of explanation, it is assumed that an external force such as wind acts on the window in a state where the window 11 is located at the closed position, and the window 11 is moved so that the window opening / closing apparatus 200 is automatically controlled.

In the prior art of FIG. 6B, unlike the present invention, the closing detection switches 283 and 275 for detecting the closing position are located at the rear end of the chain. At the rear end of the chain 251, the cumulative tolerance (including the tolerance along the pitch of the chain 251, the tolerance with the guide for guiding the chain 251, the radius of curvature of the chain guide, K2 " in Fig. 6B). Accordingly, the part number '275' corresponding to the closed indicating member of the present invention in the closing detection switches 283 and 275 is set to the actual movement of the window 11 in the closed position (see 'k0' Even if the window 11 moves by the range including the cumulative tolerance 'k2' according to the entire length, the reference numeral '283' corresponding to the closing sensing member of the present invention can not detect the opening state of the window 11 It is possible. Further, due to the somewhat large cumulative tolerance (cumulative tolerance of approximately 2-3 mm at the chain length of approximately 30 mm in the actual comparative example), the closing detection switches 283, 283 located at the rear end of the chain 151 according to the movement of the window 11, 275 detect and close the closed position. When the window 11 is slightly opened due to such an accumulated error, the window 11 is moved even under the influence of the fine wind so that the movement of the window 11 is repeatedly transmitted to the detection switches 283 and 275, , 275) may be repeatedly operated to cause repeated blinking. Also, since the type of switch used is generally a limit switch, repeated operation may cause the limit switch to fail.

Accordingly, when the control unit repeats the operation of the motor and repeats this process, it is a cause of failure of various electric parts for controlling the closing detection switches 283 and 275 and the closing detection switches 283 and 275, And the Applicant has derived the present invention after various attempts.

On the other hand, when the closing detecting member 185 for detecting the closing position of the window opening / closing apparatus 100 according to the embodiment of the present invention is installed in a closed position (not shown) of the front attachment (not shown) It is possible to eliminate the error according to the pitch of the entire chain according to the conventional technique, the error in meshing with the sprocket 153, the error with the chain guide, and the radius of curvature of the chain guide by sensing the display member 183, Only an error (see 'k1' in FIG. 6A) between the window 11 and the front attachment (see the length 'CHL1' in FIG. 6A) is added to detect that the window 11 is opened and closed. Accordingly, even if the window 11 is repeatedly opened and closed repeatedly under the influence of a typhoon or wind, the window 11 can be opened and closed with a small tolerance, indicating that the position of the closing display member 183 is hardly moved, The display member 183 can reflect the degree of opening of the window 11 without any significant error.

According to the test of the applicant of the present invention, the position of the sensing switch or the sensing member is changed in the condition of the same chain (the case where the moving stroke of the chain is 300 mm) and the window, (Refer to 'k2' in FIG. 6A) can be reduced to 0.2 to 0.3 mm (see 'km' in FIG. 6A) of 1/10. Accordingly, since the display member 183 can be moved with almost no error in the opening state of the window, when the opening and closing of the window is sensed by the sensing switch 180, there is a fear that the sensing switch 180 will operate even with a malfunction or a slight wind Can be greatly reduced. The closure detection switch in the prior art uses a limit switch, unlike the embodiment of the present invention.

This comparison example is shown in Table 1 (based on the chain stroke 300 mm).

(02-0.3mm) k1 The prior art (Figure 6b) k0 k2
(2-3 mm) k4

It can be seen that the difference in cumulative tolerance differs by about 10 times depending on the position of the display member and the position of the sensing member for sensing the same in the same condition as in the above table. In other words, in the prior art, the window can move about 10 times more or the display member can move about 10 times more. For this reason, the advantages of the present invention as described above can be more clearly understood.

Also, when the window closing device is installed in a large factory or a building, maintenance is not easy.

According to the present invention, even when a window moves due to an external force, it is easy to detect an open / close state to prevent a malfunction or a failure in a construction for detecting opening / closing of a window, and even when a window is moved by an external force, The present invention can provide an automatic window opening / closing apparatus having a switch that can easily detect an opening / closing state that can reduce an error to a user.

Also, it is possible to provide a automatic window opening / closing device having a switch which is easy to use, easy to use, easy to detect opening / closing states, which can reduce malfunction, repair and the like to increase lifetime and improve reliability of the product.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention . The scope of the invention will be determined by the appended claims and their equivalents.
