BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoistway cleaning device for cleaning a hoistway through which an elevator car ascends and descends.

0002

2. Description of the Related Art Generally, when an elevator is used for many years, dust often adheres to the landing doors, sills, and various equipment in the hoistway. In such a case, not only will it have an adverse effect such as performance deterioration on the equipment, but there is also the risk of fire starting in the hoistway due to discarded cigarettes, etc. Therefore, the inside of the hoistway should be cleaned regularly and the above-mentioned measures should be taken. Dust needs to be removed.

[0003] Conventionally, for example, Utility Model Application Publication No. 1-16668
As described in Publication No. 6, a hoistway cleaning device has been proposed in which a vacuum cleaner main body is installed on the ceiling of a car, and a suction port connected to the main body is provided at a predetermined location on the car. There is. In this conventional hoistway cleaning device, a worker grasps the dust collection hose and connects it to the above-mentioned suction port, cleans the hoistway while raising and lowering the car at low speed, and then connects the dust collection hose to the suction port after cleaning is completed. is designed to be removed from the suction port above.

0004

[Problems to be Solved by the Invention] However, in the above-mentioned conventional hoistway cleaning device, cleaning is performed while manually operating the dust collection hose using a vacuum cleaner, so it takes a long time to clean the inside of the hoistway. Therefore, the cart had to be stopped during that time, which caused inconvenience to customers. In addition, since cleaning is carried out by holding the dust collection hose, labor costs are increased as additional labor is required in addition to the driver driving the car, and the person holding the dust collection hose inhales dust, resulting in unsanitary conditions. There was a problem.

[0005] The present invention has been made in view of the actual situation in the prior art, and its purpose is to quickly clean the inside of the hoistway without having to manually hold the cleaning tool. The purpose of the present invention is to provide a hoistway cleaning device that can clean the hoistway.

[0006]

Means for Solving the Problems In order to achieve this object, the present invention provides a hoistway cleaning device for cleaning a hoistway in which an elevator car ascends and descends, in which a hoistway cleaning device that cleans a hoistway in which an elevator car is moved toward a wall of the hoistway. a first blowout nozzle that blows out wind;
The structure includes a second blowout nozzle disposed above the first blowout nozzle and blowing air downward into the hoistway, and a blower blowing air to these blowout nozzles.

[0007]

[Operation] Since the present invention is configured as described above, when the blower provided in the car is operated, air is blown from the blower to the first blowout nozzle and the second blowout nozzle, and the air is blown from the blower to the first blowout nozzle. Since the wind is blown more toward the walls of the hoistway, dust adhering to landing doors, sills, and various equipment in the hoistway is blown away and scattered around. At the same time, air is blown downward from the hoistway from the second blowout nozzle placed above the first blowout nozzle, so the scattered dust is blown downward from the hoistway. , deposited at the bottom of the hoistway. This accumulated dust is then removed. Thereby, the inside of the hoistway can be quickly cleaned without requiring the cleaning tool to be manually held.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the hoistway cleaning device of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view showing an embodiment of the hoistway cleaning device of the present invention, and FIG. 2 is a perspective view showing an elevator hoistway equipped with the hoistway cleaning device of FIG.

[0009] In general, an elevator, as shown in FIG.
It has a hoistway 1, a landing door 3 provided on a wall 2 of the hoistway 1, a sill 4, a car 5 for going up and down the hoistway 1, and a rope 6 for hoisting the car 5. The hoistway cleaning device of this embodiment, which is installed in such an elevator, is shown in FIG.
As shown in FIG. 2, a first blowout nozzle 7 installed at the bottom of the car 5 blows air toward the wall 2 of the hoistway 1, and an upper part of the first blowout nozzle 7, for example, the car 5.
a second blowout nozzle 8 which is arranged at the upper part of the hoistway 1 and blows wind downwards in the hoistway 1;
, 8 via blower pipes 7a, 8a, respectively, and a blower 9 disposed above the car 5.

In this embodiment, the operator operates the blower 9.
When activated, air is sent from the blower 9 to the first blow nozzle 7 and the second blow nozzle 8 through the blow pipes 7a and 8a, and from the first blow nozzle 7 to the wall 2 of the hoistway 1. Since the wind 10 is blown towards the hoistway 1
Dust adhering to the inner wall 2, landing door 3, sill 4, various equipment, etc. is blown away and scattered around. At the same time, since the wind 11 is blown downward from the hoistway 1 from the second blowout nozzle 8 disposed above the first blowout nozzle 7, the above-mentioned scattered dust is blown out from the hoistway 1.
is blown downward and deposited on the bottom 1a of the hoistway 1. While operating the blower 9 in this manner, the car 5 is moved up and down at low speed, for example, after it has reciprocated within the hoistway 1 two or three times, the blower 9 is stopped and the dust 1 accumulated on the bottom 1a is removed.
2 is removed.

In the embodiment configured as described above, the interior of the hoistway 1 can be quickly cleaned without requiring the cleaning tool to be manually held. In this embodiment, the blower 9 and the car 5 are operated manually by the worker, but instead of this manual operation, these operations may be performed under preset program control. If this is done automatically, labor costs can be further reduced.

0012

[Effects of the Invention] Since the present invention is constructed as described above, the inside of the hoistway can be quickly cleaned, and therefore,
Since there is no need to stop the car for a long time, there is no need to cause any major inconvenience to customers. In addition, since workers do not need to hold cleaning tools when cleaning inside the hoistway, labor costs can be reduced, and the work environment is improved by preventing workers from inhaling dust. can be made sanitary.
