Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a condensed water treatment device for a car that treats condensed water discharged from an elevator car cooling device.

[Prior Art] In recent years, elevators installed in hotels and the like have increasingly been required to be equipped with a cooling device that blows cold air into the elevator cars.

When such a cooling system is mounted on a passenger car and condensed water generated in the heat exchanger of the cooling system drips onto the outside of the car, these dripping water droplets enter equipment in the hoistway and cause damage to these equipment. This can cause rust to develop inside the equipment, or cause deterioration of the insulation of electrical parts, leading to a decline in functionality. This caused a problem in that the safety and reliability of the elevator decreased.

Therefore, conventionally, for example, as shown in Japanese Utility Model Publication No. 51-17969, a tank for storing condensed water was provided at the bottom of the car, and a solenoid valve was installed in this tank, so that the car could reach the lowest floor. It has been proposed to operate the electromagnetic valve to discharge water to a drainage port provided at the bottom of the hoistway.

[Problems to be solved by the invention] In the above-mentioned conventional technology, a drainage tank is provided at the bottom of the hoistway to receive condensed water discharged from a tank at the bottom of the car, and piping equipment is required to drain water from this drainage tank to the outside of the hoistway. There was a problem that the installation cost would be enormous. In particular, when installing a new building in an existing building, extensive building remodeling work was required. In addition, the solenoid valve installed in the tank is not only expensive, but also may malfunction due to dust mixed in with the condensed water.
There was also the problem that condensed water leaking from this solenoid valve would scatter into the hoistway. Furthermore, if there is little use of the car on the bottom floor, the car must be driven to the bottom floor in order to release condensed water from the tank, leading to concerns about a decline in service.

The purpose of this invention is to create a passenger car that can prevent condensed water from scattering in the hoistway and easily drain it without requiring expensive equipment, special equipment, or modification of the building. The purpose of the present invention is to provide a condensed water treatment device.

[Means for Achieving the Problem] The above object is to provide a tank in the lower part of the car for storing condensed water from the cooling device, and to provide a drain pipe for guiding the condensed water in the tank to the inside of the car. This is achieved by, on the one hand, providing the tank with a pump that sends out the condensed water in the tank through the drain pipe, and on the other hand, providing the interior of the car with an operating switch that operates the pump. .

[Effect]

When the operation switch installed inside the car is operated, the pump installed in the tank at the bottom of the car is activated, and the activated pump sends out the condensed water in the tank and drains it into the car through the drain pipe. be guided. This condensed water is then collected in a container or the like and carried out from inside the car to be drained. This not only eliminates the need to spray water onto the bottom of the hoistway, but also prevents condensed water from scattering within the hoistway, making it possible to easily discharge condensed water from inside the car.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a longitudinal cross-sectional view showing the main structure of an elevator equipped with a car condensed water treatment device according to an embodiment of the present invention.

In FIG. 1, 1 is a hoistway, 2 is a car that goes up and down in the hoistway 1, 3 is a floor plate provided at the bottom of the car 2, 4 is a side plate erected at the end of the old board 3, 5 is a car door attached to the side plate 4 so as to be openable and closable, and 6 is a ceiling attached to the upper end of the side plate 4. The car 2 is composed of the floor plate 3, the side plate 4, the car door 5, the ceiling 6, etc. ing. Further, 7 is a floor of the building, and 8 is an entrance/exit door provided on the floor 7 so as to be openable and closable, and facing the above-mentioned car door 5. 9 is a rope for suspending the car 1; 10 is installed at the top of the ceiling 6 of the car 2;
A cooling device 11 that sends cold air into the passenger car 2 is provided at the lower part of the floor plate 3 of the passenger car 2.
12 is a water conduit pipe that connects the cooling device 10 and the tank 11;
13 is a drain pipe that guides the condensed water in the tank 11 to the inside of the car 2; 14 is a pump that is provided between the tank 11 and the drain pipe 13 to send out the condensed water in the tank 11; An operating switch 16 is provided inside to operate the pump 14, and 16 is an electric wire connecting the operating switch 15 and the pump 14.

However, when the air conditioner 10 installed above the ceiling 6 of the passenger car 2 is operated, this air conditioner 1
The condensed water generated at 0 drips in the water pipe 12 and is stored in the tank 11. And this tank 1
When draining the condensed water in the tank 1, when the operation switch 15 provided inside the car 2 is operated, the pump 14 is activated and the condensed water in the tank 11 is pumped out. It is guided into the interior of the car 2 via a pipe 13. Therefore, this guided condensed water is received in a container or the like and carried out from inside the car 2 to be drained.

In this embodiment, since the condensed water in the tank 11 is guided into the inside of the car 2, it is not necessary to discharge water to the bottom of the hoistway 1, and the condensed water in the hoistway 1 is Splashing can be prevented, and the condensed water can be easily disposed of by a worker inside the car 2 operating the operating switch 15 or by carrying out the condensed water in a container or the like.

The operation switch 15 of the pump 14 may be attached to the operation panel in the car 6. In this embodiment, the pump 14 is provided between the tank 11 and the drain pipe 13, but the present invention is not limited to this.
4 may be provided inside the tank 11.
A detector may be provided to detect when the condensed water in the tank 11 reaches a predetermined amount, and a warning may be issued by light or sound when the amount reaches the predetermined amount requiring drainage.

[Effects of the invention] According to the invention, not only is it not necessary to spray water to the bottom of the hoistway, but also it is possible to prevent condensed water from scattering in the hoistway and easily discharge condensed water from inside the car. can do. Therefore, it is not necessary to provide a drainage tank at the bottom of the hoistway or to provide piping equipment in the building, and the cost required for equipment can be reduced, and condensed water can be efficiently treated.
