Next, the ventilator 10 will be described with reference to FIG.
FIG. 2 is a vertical cross-sectional view of the elevator ventilator according to Embodiment 1. FIG.

As shown in FIG. 2, the ventilator 10 includes a housing 12, a fan 13, a filter body 14, a charged body 15, a collecting body 16, a reporting body 17, and a lid body .

For example, the housing 12 is made of metal. The housing 12 forms an air passage connecting the outside and the inside of the car 6 . In the air passage of the housing 12, the opening on the outside of the car 6 opens horizontally. A fan 13 is provided in the air passage of the housing 12 . A fan 13 is provided so as to draw air from the outside of the car 6 and send it to the inside of the car 6 .

The filter body 14 is provided in the opening of the air passage of the housing 12 on the outside of the car 6 . The filter body 14 is provided so as to collect relatively large dust contained in the air sucked by the fan 13 . The charged body 15 is detachably provided on the outside of the car 6 relative to the fan 13 in the air passage of the housing 12 . The charged body 15 is provided so as to charge relatively small dust contained in the air that has passed through the filter body 14 . The collector 16 is detachably provided between the fan 13 and the charged body 15 in the air passage of the housing 12 . The collector 16 is provided so as to collect relatively small dust charged by the charged body 15 .

For example, the notification body 17 is provided on the upper surface of the housing 12 . The notification body 17 is provided so as to notify, by light emission or the like, that the fact is indicated when the amount of relatively small dust particles collected by the collection body 16 exceeds a preset amount. Lid 18 is provided so that it can be inserted between fan 13 and collector 16 from the outside of housing 12 . Lid 18 is provided so as to stop the operation of fan 13 , charged body 15 and collector 16 when inserted between fan 13 and collector 16 .

According to the first embodiment described above, collector 16 collects dust charged by charged body 15 . Therefore, the amount of dust flowing into the car 6 can be reduced. As a result, it is possible to prevent the interior design surface of the car 6 from becoming dirty with dust.

In addition, in the air passage of the housing 12, the opening on the outside of the car 6 opens horizontally. Therefore, it is possible to prevent the air from vigorously flowing into the housing 12 when the car 6 moves up and down.

Further, the notification body 17 notifies that the amount of dust collected by the collection body 16 has exceeded a preset amount. Therefore, the operator can be informed of the timing of cleaning the collector 16 .

Embodiment 2.
FIG. 3 is a vertical cross-sectional view of an elevator ventilator according to Embodiment 2. FIG. The same reference numerals are given to the same or corresponding parts as those of the first embodiment. Description of this part is omitted.

In Embodiment 2, the housing 12 forms an upper air passage 12a, a folded air passage 12b, and a lower air passage 12c.

The upper air passage 12a extends horizontally from the outside of the car 6. As shown in FIG. The folded air passage 12b is folded downward from the upper air passage 12a. The lower air duct 12c extends downward from the upper air duct 12a from the folded air duct 12b and connects to the inside of the car 6.例文帳に追加

The fan 13 is provided in the lower air passage 12c. The charged body 15 is provided closer to the folded air passage 12b than the fan 13 in the lower air passage 12c. The collector 16 is provided between the fan 13 and the charged body 15 in the lower air passage 12c.

According to the second embodiment described above, the housing 12 forms an air passage by being folded downward. Therefore, the installation area of the ventilation device 10 on the ceiling of the car 6 can be reduced.

Moreover, the charged body 15 and the collector 16 are provided in the lower air passage 12c. Therefore, oil from the pair of guide rails of the car 6 and the pair of guide rails of the counterweight 7 can be more reliably prevented from reaching the charged body 15 and the collector 16 .

Note that the housing 12 may be divided at the boundary between the upper air passage 12a and the lower air passage 12c. In this case, if the charged body 15 and the collector 16 are exposed upward when the upper air duct 12a is removed from the lower air duct 12c, the charged body 15 and the collector 16 can be easily cleaned. can.

Embodiment 3.
FIG. 4 is a cross-sectional view of an elevator ventilator according to Embodiment 3. FIG. The same reference numerals are given to the same or corresponding parts as those of the first embodiment. Description of this part is omitted.

In Embodiment 3, the housing 12 forms a first air passage 12d, a folded air passage 12e, and a second air passage 12f.

The first air passage 12d extends horizontally from the outside of the car 6. As shown in FIG. The folded air passage 12e is laterally folded back from the upper air passage 12a. The second air passage 12f extends from the return air passage 12e along the first air passage 12d and connects to the inside of the car 6. As shown in FIG.

A fan 13 is provided in the second air passage 12f. The charged body 15 is provided closer to the return air passage 12e than the fan 13 in the second air passage 12f. The collector 16 is provided between the fan 13 and the charged body 15 in the second air passage 12f.

According to the third embodiment described above, the housing 12 forms an air passage by being folded back in the lateral direction. Therefore, the height of the ventilator 10 can be lowered on the ceiling of the car 6 .

Moreover, the charged body 15 and the collecting body 16 are provided in the second air passage 12f. Therefore, oil from the pair of guide rails of the car 6 and the pair of guide rails of the counterweight 7 can be more reliably prevented from reaching the charged body 15 and the collector 16 .

A cover 18 may be provided on the upper surface of the second air passage 12f. In this case, if the charged body 15 and the collector 16 are exposed upward by opening the cover 18, the charged body 15 and the collector 16 can be easily cleaned.

In the air passage of the housing 12 of the ventilator 10 of Embodiments 1 to 3, the opening on the outside of the car 6 is connected to the pair of guide rails of the car 6 and the pair of guides of the counterweight 7. Just make sure it doesn't face the rail. For example, the opening on the exterior side of the car 6 may be directed between the pair of guide rails of the counterweight 7 . In this case, oil from the guide rail can be more reliably prevented from entering the air passage of the housing 12 .

Further, in the housing 12 of the ventilator 10 according to Embodiments 1 to 3, the insertion part of the nozzle of the cleaner may be formed in the vicinity of the dust collector. In this case, the dust collector can be cleaned safely and efficiently by stopping the operation of the fan 13, the charged body 15, and the dust collector when the nozzle of the cleaner is inserted into the insertion portion. can.

Further, in the ventilator 10 according to Embodiments 1 to 3, when the operation of the fan 13 is stopped, the operation of the charged body 15 and the dust collector may also be stopped. In this case, it is possible to prevent the charged body 15 and the dust collecting body from operating unnecessarily when the fan 13 is stopped in winter or the like.
