Abstract

PURPOSE:To eliminate trouble caused by bad water-draining or water-splashing and prevent drain noise from being generated, by installing a drainpipe of a flexible pipe on a drain tank for the drain of an air conditioner in a cage and installing a drain vessel under the end of the drainpipe when the cage reaches the lowest floor CONSTITUTION:A drain pipe 6 of a drainage device end consists of a flexible pipe 11 having a length reaching a travel range outside 12 a cage 1. Besides, a drain vessel 9 is installed in the travel range outside 12 and under the end of the flexible pipe 11 and on the side of an elevator shaft 8 in the travel range outside 12 where a gap H between the flexible pipe 11 and the drain vessel 9 becomes minimum when the cage 1 reaches the lowest floor level. The end part of drainage piping is thus formed of the flexible pipe 11 and the drain vessel 9 is installed in such an optimum place that equipment in the elevator shaft 8 is prevented from being affected by bad water-draining or water- splashing, drain noise is prevented from being generated and mutual damage is prevented from being caused by clashing when the cage 1 is pushed down.

なってきた。2. Description of the Related Art In recent years, in various buildings, there is an increasing tendency to air-condition the entire interior of the building, so that not only living rooms but also passages or elevator halls have become conspicuous.

付きのエレベータが設置されるようになってきた。Along with this, there are many cases where the car is equipped with a heating and cooling device in order to provide a more comfortable environment for passengers of the elevator, and in particular, the glass provided on the side wall of the hoistway of the building and the car like the elevator for observation. There is a tendency that the number of elevators with air conditioners increases more and more because the passengers who receive direct sunlight rather than the surface also have a greater discomfort to passengers. In cold regions, elevators equipped with a heating / cooling device have also been installed.

処理が試みられている。By the way, when the air conditioner is operated, drainage is generated from the surface of the heat exchanger. However, since various devices are installed in the elevator hoistway, the drainage can be naturally discharged. Instead, various drain treatments have been attempted.

【０００５】ここで、従来のエレベータにおける冷暖房
器のドレン処理装置の例を図４を参照して説明する。An example of a conventional drainage treatment device for an air conditioner in an elevator will be described with reference to FIG.

磁弁５の後方にも先端排水管７が接続される。A cooling / heating machine 2 is installed above the car 1, and drain generated from the cooling / heating machine 2 is stored in a drain tank 4 via a hose 3. Further, an electromagnetic valve 5 is provided behind the tank 4 and is connected by a drain pipe 6, and a tip drain pipe 7 is also connected behind the electromagnetic valve 5.

うになっている。Further, a drainage container 9 is installed in the hoistway 8, and when the car 1 arrives at the lowest floor, a solenoid valve 5 is opened by receiving a signal and the drain accumulated in the drain tank 4 is discharged. It is designed to be discharged to the drainage container 9 via the tip drainage pipe 7.

係を満たす必要がある。In the above conventional drain treatment device, the distance H between the tip drain pipe 7 and the drain container 9 is high.
Is more effective in consideration of drain drainage or splashing, but the elevator car 1 does not always stop at the level of the standard floor, and when the car 1 is pushed down, the running margin and the buffer 10 If the descending distance S including the stroke is not taken into consideration, the tip drainage pipe 7 and the drainage container 9 will collide and be damaged, and it is necessary to satisfy the relationship of H> S.

Since the stroke of 0 is large, the descending distance S is also large, and the distance H between the tip drainage pipe 7 and the drainage container 9 is wide, so that the drainage or splashing of the drain becomes a serious problem. When the distance H between the tip drainage pipe 7 and the drainage container 9 becomes wide, the drainage discharged from the tip drainage pipe 7 collides with the drainage container 9 or the drainage accumulated in the drainage container 9, and a large drainage sound is generated at that time. And it leads to the image down of the elevator.

ようにするものである。[Means for Solving the Problems] The drain pipe at the tip of the drain treatment device is made up of a flexible pipe, and the drain container is placed outside the running area of the car, and immediately below the tip of the flexible pipe, and the car is at the bottom. It is arranged so that the space H between the flexible pipe and the drainage container upon arrival at the floor level is minimized.

互の破損が生じないですむ。In the drain treatment device having such a structure, the distance H between the tip drainage pipe and the drainage container can always be set to the minimum, and when the car is pushed down, the flexible pipe is deformed immediately after touching the drainage container. Since they run away, mutual damage due to collision does not occur.
