  Hereinafter, preferred embodiments of an elevator cab according to the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is a plan view showing an elevator cab in the first embodiment of the present invention, and FIG. 2 is a front view showing the elevator cab in the first embodiment of the present invention. The elevator cab of the first embodiment shown in FIGS. 1 and 2 includes a car wall 1, a car ceiling 2, a doorway 3, a car fan 11, a fan cover 12, and a mist generator 13 containing platinum. (Hereinafter simply referred to as a mist generating device).

  As described in the background art, the interior of the car may be uncomfortable, such as an installation environment or a strange odor due to dirt, and the application of the air purifier 21 is often required. Therefore, in the elevator cab of the first embodiment, by providing the cab fan 11, the fan cover 12, and the mist generating device 13 on the cab 2 of the elevator, Uses different methods to clean the air.

  Therefore, the air cleaning method in the first embodiment will be specifically described below. In the first embodiment, as shown in FIGS. 1 and 2, a mist generating device 13 is installed in the vicinity of the cab fan 11 attached to the cab. The mist generator 13 is installed leeward with respect to the cab fan 11. As a result, mist can be mixed into the air blown from the car room fan 11 and discharged into the car room.

  Next, the detail of the mist generator 13 containing platinum is demonstrated. By applying a high voltage electrode to the condensed water generated by the Peltier element in the mist generator 13 at a high voltage of DC 4 to 5 KV, the mist is made into a nano size. At that time, platinum can be mixed into the mist by allowing the condensed water to pass through the felt containing platinum nanocolloids to elute platinum into the condensed water. The platinum nanocolloid-containing felt is taken into the mist generating device 13 and elutes platinum by passing condensed water.

  FIG. 3 is a detailed view of the fan cover of the elevator cab in Embodiment 1 of the present invention. FIG. 4 is an attachment diagram of the mist generating apparatus according to Embodiment 1 of the present invention. As an example of the installation procedure of the mist generating device 13 containing platinum, as shown in FIGS. 3 and 4, a fan cover 12 is attached to a cab fan 11 installed in a car, and a mounting metal is attached to the inner surface of the fan cover 12. 14 is installed. The fixing method can be any method such as a screw or a rivet.

  When the mist generating device 13 is installed on the windward side of the cab fan 11, the mist passes through the cab fan 11, and the mist collides with the cab fan 11 and the amount of discharge into the cab is reduced. . Therefore, it is desirable that the mist generator 13 be disposed leeward with respect to the cab fan 11.

  By adjusting the mist containing platinum to an appropriate injection speed, air volume, and wind direction, it is possible to intentionally collapse the mist at a target height and generate a partial humidity distribution in the car room. Thereby, it is possible to efficiently carry out antiviral and antibacterial treatment only in a necessary range corresponding to a small space such as the height of the passenger's face. The mist injection speed, the air volume, and the wind direction can be adjusted by the mist generator itself, or the cab fan 11 can be adjusted by the wind speed, air volume, and air flow direction. It can be adjusted.

  FIG. 5 is a front view showing the elevator cab in Embodiment 1 of the present invention, and shows a configuration including an operation panel 4. Depending on the installation position of the car room fan 11, direct injection onto the wall surface 1, the operation panel 4 and the like of the car room is also possible. As a result, not only a small space such as the height of the passenger's face but also an effect on bacteria attached to the wall surface 1 of the cab, the operation panel 4 and the like can be easily obtained.

  As for the air volume, if the height of the passenger's face is 0.5 m / s or less, it is possible to obtain an effect while reducing the feeling of blowing (that is, as an unpleasant wind speed). It is. Therefore, by narrowing the area (opening) of the blowout port into the car, for example, if the blown wind speed is about 1 m / s, it can be set to 0.5 m / s about 1 m away from the human body. With the above wind speed, mist is attracted to the human body by static electricity. Therefore, even if it is not sprayed directly on the human body, it is possible to obtain an effect if it can be blown out to a certain degree.

  As described above, by using platinum-containing mist generating device 13 for air purification in the car room, platinum has viruses / bacteria removal, skin-beautifying and moisturizing effect by antioxidant action, and mold / allergen removal by mist effect. Effects such as a deodorizing effect can be easily obtained in the elevator cab.

  If it is going to change the wall 1 of the cab or the operation panel 4 to the antibacterial specification instead of the technology of the first embodiment, development is required for each finishing and model name, and a huge development load and time are required. . On the other hand, in the technique of the first embodiment, it is possible to easily achieve antibacterial / virus removal specifications without applying such a load.

  Further, in the conventional air purifier 21, it is possible to add functions such as the removal of viruses or the like floating in the air by circulating the air in the entire car room. However, when the air in the entire cab is circulated, the volume is large and the cleaning efficiency is poor. Moreover, there is no removal effect with respect to adherent bacteria.

  On the other hand, in this technique using the mist generating apparatus containing platinum, since it becomes possible to obtain a pinpoint effect against a small space and attached bacteria, the cleaning efficiency is also high.

Furthermore, by installing the mist generating device 13 in the elevator cab, the following advantages can be obtained as compared with the conventional cab cleaning by the air cleaner 21.
[Advantage 1] Large-scale equipment placement on the basket is not required.
[Advantage 2] Small space, pinpoint effects (floating bacteria, adherent bacteria, etc.) are possible.
[Advantage 3] It is not necessary to use a circulation type, and it is not necessary to have a cage structure that secures the air path of the suction port / blowout port.
[Advantage 4] There is no air filter, and regular maintenance work such as cleaning is unnecessary.
[Advantage 5] There is almost no weight increase, and no weight restriction occurs.

  Furthermore, if the air cleaner 21 is to be installed on an existing elevator as in the prior art, it takes a lot of work such as processing for mounting and modification or replacement of the cab ceiling 2. On the other hand, in the present method using the mist generating device, it is possible to save on-site processing only by installing the fan cover 12 and the mist generating device 13 in the vicinity of the cab fan 11.

  As described above, according to the first embodiment, by using a mist generating device containing platinum instead of an air purifier, platinum has virus / bacteria removal, anti-oxidation beautifying skin and moisturizing effect, and Effects such as mold / allergen removal and deodorization effect due to the mist effect can be easily realized in the elevator cab and the air cleaning function can be improved. Furthermore, a fan and a mist generating device may be installed, and compared with the conventional circulation type air purifier, the installation conditions are relaxed, and the merit of facilitating maintenance work and on-site processing work can be obtained.
