The present invention relates to an air circulation system inside an elevator cage, and more particularly, to an air circulation system inside an elevator cage in which the installation is convenient and the interior effect is greatly improved.

1 is a schematic diagram showing an air circulation system inside a conventional elevator cage.

As shown in the drawing, an exit for exiting a passenger in an emergency is formed on a ceiling inside a conventional elevator cage, and a rough ceiling 3 covering the exit is formed. Cho Chun-jeong (3) simply serves as a reputation to cover the way out of the aesthetic view. In addition, light fixtures 5 are disposed slightly below both sides of the Jocheonjung, respectively, and the approximately U-shaped light shielding mechanisms are provided to prevent the light of the light fixtures from directly shining in the passenger's eyes and cover the light fixtures in appearance. 7) is installed under each luminaire 5. In the conventional elevator having such a configuration, the wind from the blower (B) enters the inside of the elevator cage through the ventilation holes 2 formed at both ends of the cage ceiling, and circulates as shown by the arrow.

In such a configuration, the light shielding mechanism (7) prevents the user's eyes from being uncomfortable due to the light emitted from the lighting device (5), but resists ventilation and prevents smooth ventilation, It is necessary to remove and clean the light shielding device 7 periodically because the dust is easily wrapped on the top of the light shielding device 7, and when the lighting device 5 needs to be replaced, it is inconvenient because of the narrow space between the ceiling and the light shielding device. .

In this configuration, although the ventilation inside the elevator cage proceeds in the direction of the arrow, as shown in the drawing, the jocheonjeong (3) is planar, so that the rising air flow hits the jocheonjeong at almost the water level, and then changes direction at right angles. However, there is a problem that air flow is not smooth. In addition, the ascending and laterally curved air path again hits the sidewall of the lighting shield 7 and must pass through the narrow passageway between the top of the sidewall and the ceiling ceiling, further blocking air convection inside the cage. do.

In addition, since the light of the luminaire completely illuminates the interior of the elevator with only the reflected light reflected from the ceiling and the wall of the elevator, the required illuminance is lowered, thereby lowering the lighting effect.

The present invention has been made in view of the above-mentioned problems in the prior art, while improving the structure of the conventional ceiling and lighting shielding mechanism to further promote the air convection, while significantly improving the air circulation inside the elevator cage, It is aimed at restructuring to further enhance the aesthetics inside the cage.

In addition, in the air circulation system according to the present invention, one of the luminaires 5 on both sides of the cage includes a first ultraviolet lamp (U1) for generating UV-A having a wavelength of 315 ~ 380nm, the other The luminaire includes a second ultraviolet lamp (U2) that generates UV-C having a wavelength of 100 to 280 nm, and a photocatalyst that combines ultrafine titanium oxide with an inorganic binder to form a transparent film having high hardness and acid resistance. It is preferable to coat on the fin (7-1; 7-2) on the side where (U1) is installed. In this case, it is more preferable to form a plurality of windows 20 made of hard glass or quartz glass in a portion directly under the ultraviolet lamp U2 of the lighting shielding mechanism 7 on which the second ultraviolet lamp U2 is installed.

In addition, in the present invention, a narrow mount rail 30 having an uneven portion 32 into which a screw or a bolt is inserted along the elevator cage ceiling over the entire length in the longitudinal direction is provided on the cage ceiling by bolting or the like. These mount rails 30 are configured to be male-to-female fitted to each other with respect to each other, and a plurality of hangers 35 having approximately L-shaped sides along the mount rails 30 are installed by bolting or the like at intervals required. Preferably, the light shielding mechanism 7 is installed in the lower horizontal section 37 of the hanger 35.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a cross-sectional view of an elevator cage schematically showing the air circulation system according to the present invention.

As shown in Fig. 2, the rough ceiling 3, which covers the escape opening 1 of the aesthetic elevator cage ceiling, has a convex shape that is arcuate in cross section unlike a conventional flat type. It goes without saying that the arched ceiling extends a part of the length of the ceiling of the elevator in the direction perpendicular to the drawing. In addition, in order to block the light of the luminaire 5 directly from the passenger's eyes on both sides of the Jocheonjeong, a light shielding mechanism 7 having a substantially U-shaped cross section installed under the luminaire and covering the luminaire is provided.

Both side wall portions of the lighting shield 7 have a structure in which a plurality of rectangular, thin, long slits 7-1; 7-2 are arranged with a gap between them, and look like a rubbe from the outside. Such a method of installing and fixing the pin will be described later. Among these many beams, the beam 7-1 towards the center of the elevator cage, i.e. the wheel 7-1 located inside the view in the drawing, is arranged at an angle that prevents the light of the luminaire 5 from shining directly on the passenger. And preferably arranged horizontally. The wheels 7-2 on the side wall of the elevator cage, i.e., the wheels 7-2 on the outer side, are arranged at an angle inclined downward toward the side wall of the cage so that air can pass smoothly therebetween. desirable.

3 is a cross-sectional view showing in detail the mounting structure of the jocheonjeong (3), the upper side, the state is assembled with the jocheonjeong, the lower shows the state the jocheonjeong separated.

As shown, the fixture 10 is attached to both ends of the ceiling ceiling (3) and the mount 12 corresponding to the fixture 10 is installed on the ceiling of the cage, the fixture 10 and the mount 12 is male and female coupling Is fitted with Fixture 10 and the mount 12 has a structure that is fitted to each other in a male-to-female manner, preferably in the form of a long rail in the vertical direction in the figure. The mount 12 is coupled to the elevator cage ceiling by screws or bolts, and the fastener 10 can be easily disassembled by inserting or removing the fixture 10 on the mount. In addition, by connecting the fixture 10 and the mount 12 with a string 14 such as a chain of a predetermined length, it is possible to freely drop the falling ceiling from falling so that the rough ceiling 3 is not completely separated from the mount 12. It is preferable because there is no risk. Connecting the fixture to the mount with such a string 14, after opening the jocheonjeong (3) and emergency escape through the escape port (1) will be able to easily assemble the jocheonjeong (3) in its original state.

On the other hand, according to the recent well-being trend, there is a tendency to replace a part of the luminaire of the elevator with ultraviolet sterilization lamp. There are various sterilization lamps, but UV sterilization lamps are most often used. UV sterilization lamps use glass that passes ultraviolet rays specially, and the inside contains low pressure (about 0.133 Pa) of mercury vapor and radiates ultraviolet rays generated by electric discharge to the outside through glass with high transmittance. Ultraviolet rays do not penetrate materials other than air and water, but they are used for disinfection of tableware, medical equipment, sanitary parts, etc. in addition to air and water sterilization. When UV rays are irradiated for 1-2 minutes at 50cm away from a 15W germicidal lamp, E. coli, dysentery and staphylococci are sterilized more than 99.9%, and sterilization is carried out only in close proximity to UV rays. However, if the ultraviolet light shines directly on a person's eyes, the eyes are injured.

The present invention is also prepared in the case of using such ultraviolet sterilization lamp. For example, one of the luminaires 5 on both sides of the cage is provided with a first ultraviolet lamp U1 that generates UV-A having a wavelength of 315-380 nm, and the other luminaire has a UV having a wavelength of 100-280 nm. In some cases, a second ultraviolet lamp U2 for generating -C is provided. Since UV-C is far more potent than UV-A, the risk is much greater when directly irradiated with the body. In addition, UV-A effectively acts as a bactericidal power when reacting with a photocatalyst such as TiO2. In view of these features, it is preferable to coat the photocatalyst on the caps 7-1 and 7-2 of the lighting shielding mechanism on the side where the UV-A ultraviolet lamp U1 is installed. That is, it is preferable to coat the photocatalyst in which the ultrafine titanium oxide is combined with the inorganic binder to form a high hardness acid resistant transparent film on the fins 7-1; 7-2 on the side where the first ultraviolet lamp U1 is installed.

In addition, since the ultraviolet lamp (U2) emits a blue light, if used well, it can not only significantly improve the aesthetics in the interior aspect of the elevator, but also can visually check whether there is lighting. The present invention forms a plurality of windows 20 made of hard glass or quartz glass in the light shielding mechanism 7 directly under the ultraviolet lamp U2 for this aesthetic improvement and safe use. The shape of the window 20 may take any shape as necessary, such as a circle or a triangle, but the present invention will be described taking a circular shape as an example.

4 is a cross-sectional view showing the window 20 in detail, with an exploded view of the window 20 below.

As shown, the window 20 is made of hard glass or quartz glass to prevent the passage of UV-C, and is installed in the hole formed in the light shielding mechanism 7 by an inner and outer frame. If a plurality of such windows 20 are installed at regular intervals along the ultraviolet lamp U2 or formed in an elongated shape, the passenger or the manager can easily check the lighting state of the ultraviolet lamp through the window 20. In general, blue light will be seen through window 20. Therefore, while blocking the ultraviolet rays dangerous to the body, the lighting state can be confirmed, as well as excellent interior effect in terms of aesthetics. On the other hand, such UV lamps are dangerous when exposed to the body, so install a warning (W / W) to cut off the power of the UV lamp and warning signs warning the danger of exposure to the body in the visible position of the light shield mechanism (7) It would be desirable. In this case, when working for repair or replacement of the ultraviolet lamp, it is possible to ensure the safety of the operator. 9 shows an example of such a warning message and a switch.

5 is an exploded perspective view of a mounting structure for installing a light shielding mechanism, and FIG. 6 is a cross-sectional view showing a relationship between the mount rails 30.

As shown, at least one narrow and elongated mount rail 30 is installed side by side in the elevator cage ceiling. Uneven portions 32 are formed continuously in these mount rails 30 in the longitudinal direction, and the uneven portions 32 are divided into upper and lower portions. Fasteners, such as screws or bolts, are inserted into the uneven parts 32. Fasteners to be fixed to the cage ceiling are inserted into the uneven parts, and fasteners to fix the hanger 35 to be described later are inserted into the uneven parts. In addition, these mount rails 30 are configured to be male and female fit at the side portions with respect to each other (see Fig. 6). Since the concave-convex portion 32 is continuously formed along the mount rail 30, the fasteners can be freely appropriately arranged at the necessary intervals according to the work space. In addition, since the mount rails 30 can be coupled side by side as many as necessary, the appropriate number of mount rails 30 can be installed without covering the ventilation holes 2 formed in the cage ceiling.

A plurality of hangers 35 having an approximately L-shaped side along the mount rail 30 are installed by bolting or the like at a necessary interval. The hanger 35 is composed of a horizontal section 37 and a vertical section 36 at the bottom, and the light shielding mechanism 7 is installed in the lower horizontal section 37 by bolting or the like. On the other hand, it is preferable that a plurality of inclined grooves 34 are formed in the vertical section 36 of the hanger 35 at appropriate intervals, and each of the grooves 7-2 is fitted to these grooves 34. This makes it extremely easy to decompose the bond.

7 is a side view showing the installation method of the rack holder 40 for installing the other wheel (7-1).

As shown, it is preferable that the shock mount 40 is vertically detachably installed at the front end of the horizontal section 37 of the hanger 35. Of course, the cradle holder may be formed integrally with the hanger, but in this case, since the work space is narrow and the replacement of the lighting fixture 5 becomes very inconvenient, the cradle 40 may be detachably configured. In addition, it is preferable to form a plurality of grooves 42 along the height of the rib holder 40, and to fit the ribs 7-1 to these grooves 42, respectively. In addition, the detachable method of the hanger 35 and the shock mount 40 is most preferably made of a magnet. For example, the magnets may be attached to the front ends of the horizontal sections 37 at appropriate intervals, and the magnets or magnetic materials may be attached to the lower ends of the holders 40 correspondingly. In this configuration, since the operator can easily detach the holder 40 as necessary, it is extremely easy to replace the lamp and maintenance.

In this way, the jaw (7-1) may be installed on the holder 40, but the present invention also includes other installation methods. For example, an upward protrusion is formed at one end of the lighting shield 7, that is, at the front end toward the inside of the elevator, and as described above, a plurality of grooves are formed at the upward protrusion, and then a recess (7-1) is formed in these grooves. You can also fit

On the other hand, Figure 8 shows another embodiment of the present invention. That is, when a plurality of inclined grooves 38 are formed in the lower portion of the horizontal section 37 of the hanger 35, and the thin and long rectangular plates 50 are fitted in these grooves, the ventilation inside the cage is smoothed. Of course, the inclination of the plate 50 preferably takes an angle at which light from the luminaire is not directly irradiated to the passengers.

According to the present invention configured as described above, while the air circulation inside the elevator cage is more smoothly compared to the structure of the conventional ceiling and light shielding mechanism, the aesthetic sense of the interior of the elevator is dramatically improved from the interior side, as well as the elevator cage It can meet the well-being trend of replacing part of lighting fixtures with ultraviolet disinfection lamps for sterilization purpose to improve the sanitary condition of the interior, and greatly improves lighting replacement work and maintenance.
