JPH06191745A - Drain disposing device for room cooler in elevator - Google Patents

Abstract

PURPOSE:To surely prevent leak water from dropping into a car room by setting up a drain receiving plate and a drain leak water receiving case under a storage tank, and stopping a cooler when detected the leak water, in an elevator where in a drain from the cooler, mounted on a car, is stored in the storage tank. CONSTITUTION:In an elevator wherein cooling air obtained in a cooler 4, set up on a roof 2 of a car room 1, is blown into the car room 1 through a duct 3, a drain generated by the cooler 4 is dropped into a drain receiving plate 5 in the cooler 4, stored, drawn out to a storage tank 10 through a drain hose 8 and a drain duct 9 and discharged as necessary to the outside of a lift path. Here are provided a cooler leak water receiving case 6 and a storage tank leak water receiving case 11, capable of flowing a fixed time amount, under the cooler 4 and the storage tank 10. Float switches 7, 12 are provided in each leak water receiving case 6, 11, and when detected leak water by these float switches 7, 12, the cooler 4 is stopped.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device installed in an elevator car, and more particularly to a drain treatment device when drainage generated from the cooling device leaks water.

[0002]

2. Description of the Related Art When installing a cooling device in an elevator,
A method is generally known in which a cooling device is mounted on a car for the purpose of cooling the inside of the car, and cool air is blown into the car from a ceiling portion. The structures of these prior arts will be described with reference to the drawings. In FIG. 3, the cooling device 4 is installed on the ceiling 2 of the car room 1, and cool air is blown through the duct 3 into the car room 1.
Is blown into. At this time, the drain generated by the heat exchange of the cooling device 4 is dripped and accumulated in the drain tray 5 incorporated inside the cooling device 4, and the drain hose 8 and the drain duct 9
Is guided to the drainage tank 10, and the drainage treatment is carried out up and down as necessary. The problem here is that if the drain overflows from the drain tray 5 and leaks due to some reason (for example, the drain tray 5 or the drain hose 8 is clogged), it will drip onto the car ceiling and then flood into the car room. It will be. Therefore, this conventional technique adversely affects the ceiling lighting fixture and other electric devices and causes a failure of the elevator such as electric leakage. Further, not only will the passengers in the car feel uncomfortable due to the water, but the interior materials of the car will also become dirty. There are also cases in which the car, floor, and carpet were contaminated by water leakage, and expensive replacement was required. For this reason, the elevator car must be stopped to constantly check whether or not each part of the cooling device is clogged, and maintenance is complicated and uneconomical.

[0003]

SUMMARY OF THE INVENTION According to the present invention, when a cooling device is mounted on an elevator car, when the drain leaks water, the cooling device is detected and the cooling device is stopped to provide a safe and economical cooling device. It is to provide a drain processing device.

[0004]

According to the present invention, when drainage generated from a cooling device provided on a car leaks, the cooling device is stopped when the drain leaks in order to prevent water from flooding inside the car. It is a thing.

[0005]

By operating the drain water leakage detection switch and the cooling device, if the drain leaks, the cooling device stops, so that the drain does not drip onto the car ceiling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

1 and 2, a cooling device 4 is installed on a ceiling 2 of a car room 1. When the cooling device 4 operates, cool air is blown into the car room 1 through a duct 3. At this time, the drain generated by the heat exchange of the cooling device 4 is dripped and accumulated in the drain pan 5 incorporated inside the cooling device 4, and is guided to the drain tank 10 via the drain hose 8 and the drain duct 9. If necessary, it will be drained to the outside of the hoistway. On the other hand, below the cooling device 4 and the storage tank 10, a cooling device water leakage receiving box 6 and a storage tank water leakage receiving box 11 having a capacity capable of storing for a certain period of time are provided.
11 is provided with storage boxes 6a and 11a for storing the drain, which has a gradient such that the drain flows easily.
Drain water leakage detection switches 7 and 12 (flow switches) for detecting the drain accumulated in a and 11a are installed, respectively. In such a cooling device, should the drain pan 5 of the cooling device 4 be clogged with dust, the drain overflows from the drain pan 5 and drops into the cooling device water leak receiving box 6 to be provided in the water leak receiving box 6. The water leakage detection switch 7 is operated to indicate that water is leaking (not particularly shown), and the operation of the cooling device is stopped. In addition, even if the drain in the storage tank 10 is dropped for some reason, or if the drain hose 14 part installed on the lower surface of the storage tank is deteriorated and the drain leaks, the water leak detection switch 12 is also activated. When it operates and the leak is displayed, the operation of the cooling device is stopped.

[0008]

According to the present invention, even if the drain generated from the cooling device leaks or the drain of the storage tank leaks, the leak does not always drip into the cab and the operation of the cooling device is stopped. Therefore, the safety of various devices installed in the basket is high. In addition, the fact that water is leaking is displayed, making maintenance easy and economical.
