Japanese Patent Laid-Open No. 9-30759

  In the conventional clean elevator as described above, the air flow path in the upper part of the car is formed so as to avoid the exit and the wind speed of the air supplied into the car room is uneven. As a result, there is a place where dust stays in the car room, so the cleanliness of the car room cannot be kept uniform, and the cleanliness of the car room is lowered.

  The present invention has been made in order to solve the above-described problems, and is capable of making the air velocity of the air supplied into the car room uniform without being affected by the rescue outlet, and cleaning the car room. An object of the present invention is to obtain a car device for a clean elevator capable of improving the degree.

  A car device for a clean elevator according to the present invention has a ceiling back space that is a space between a ceiling portion and an upper surface portion, and an underfloor space that is a space between a floor portion and a bottom surface portion, and is opened and closed on the upper surface portion. A car room body provided with a possible rescue port, a ceiling member attached to the ceiling of the car room body and provided with a plurality of vent holes, and a place facing the area of the rescue room is removable, and the floor of the car room body A floor member provided with a plurality of ventilation holes, an air flow path forming member that forms an air flow path that guides air in the underfloor space to the ceiling space, and an upper surface portion of the cab body in the ceiling space. Air that is provided so as to be parallel to the air outlet and that is connected to a main filter for air cleaning that can be attached and detached, and an air flow path that faces the rescue area, and is sucked from inside the cab body through the air flow path Through the main filter. It is those with a fan to be.

  In the car device for a clean elevator according to the present invention, the portion facing the area of the ceiling member and the rescue outlet of the main filter is detachable, so the purified air is layered from the entire surface of the ceiling portion into the car room body. By being supplied in a flow state, the air speed of the air supplied into the car room can be made uniform without being affected by the rescue outlet, and the cleanliness in the car room body can be improved.

  Next, the operation will be described. FIG. 10 is an explanatory diagram for explaining the ventilation operation by the fan 19 of FIG. 1 (showing a state in which a person is loaded in the cab body 1). First, by operating a power switch (not shown), the rotation of the fan 19 is started, and the rotation of the fan 19 causes the air in the cab body 1 to be connected to the floor vent of the grating material 13. The air is sucked into the side air flow path 1j through the mouth 7a and the underfloor prefilter 8. At this time, dust, dust, and the like dropped from the cargo (passengers and luggage) in the cab body 1 are collected by the underfloor prefilter 8.

  Then, the air that has passed through the underfloor prefilter 8 is sucked into the fan box 16 from the side air flow path 1 j and sucked into the fan 19 from the air inlet of the fan 19. The air sucked into the fan 19 is discharged into the supply space 14 a by the rotation of the fan 19, purified (dust collection) by the first and second main filters 25 and 26, and the first and second ceiling members 11. , 12 are supplied into the cab body 1 in a laminar flow form from the ceiling vent holes. Then, the air flowing in the cab main body 1 is again sucked into the side air flow path 1j through the floor vent of the grating material 13, the connection port 7a, and the underfloor prefilter 8.

  Further, the rotation of the fan 19 causes the air in the hoistway to be sucked into the fan box 16 from the air intake port 16d and discharged into the supply space 14a together with the air from the side air flow path 1j. Thereby, the air which flowed out from the car door 4 periphery to the car room main body 1 exterior is supplemented with the air suck | inhaled from the air inlet 16d.

  In the car device for the clean elevator as described above, since the first ceiling member 11 and the first main filter 25 facing the area of the rescue outlet 14b are detachable, the interior of the car room body 1 can be seen from the entire surface of the ceiling 1e. Further, the purified air is supplied in a laminar flow, so that the air speed of the air supplied into the car room body 1 can be made uniform without being affected by the rescue outlet 14b. The cleanliness within 1 can be improved. As a result, even parts that require high cleanliness, such as semiconductor parts, can be loaded and transported in the cab body 1.

  Moreover, since the grating material 13 is detachable from above, the work efficiency at the time of checking the underfloor prefilter 8 can be improved.

  Furthermore, since the dust and dust that have fallen from the human cargo are collected by the underfloor filter 8 and the wire mesh 18, the load on the first and second main filters 25 and 26 can be reduced. At the same time, since the wire mesh 18 is attached to the suction portion of the fan 19, it is possible to prevent large dust from entering the supply space 14a when the underfloor prefilter 8 is damaged.

  Furthermore, since the air that has flowed out of the car door 4 to the outside of the car room body 1 is supplemented by the air sucked from the air intake port 16d, the purified air is stably supplied into the car room body 1. be able to.

  Moreover, since the fan box 16 is provided with the internal inspection port 16b and the external inspection port 16c, the work efficiency at the time of the fan 19 inspection can be improved.

  Further, since the side shielding member 31 is attached to the side surface of the car door 4 on the door opening direction side and the leg shielding member 36 is attached to the lower part of the car door 4, the car door 4 and the car doorway 1h. By shielding the gap between them, it is possible to minimize the outflow of the purified air in the cab body 1 to the outside of the cab body 1.

  In the first embodiment, the four second ceiling members 12 and the second main filter 26 are used. However, the second ceiling member 12 and the second main filter 26 are not limited to four, 1-3 or 5 or more may be sufficient.

It is a rear view which shows the outline of the cage apparatus for clean elevators by Embodiment 1 of this invention. It is sectional drawing which follows the II-II line | wire of FIG. FIG. 3 is an enlarged side view showing a lower portion of the cab main body of FIG. It is a top view which shows the clean unit 14 and the fan box 16 of FIG.
