Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to treatment of condensed water in a cooling device attached to an elevator car.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram showing a method of treating condensed water in a conventional elevator car cooling device, in which 1 is an elevator car, 2 is a cooling device body, 3 is a downcomer pipe, and 4 is a downcomer pipe.
Is a condensate storage tank, 5 is a hose, 6 is a water receiver, 7 is a drain pipe, 8 is a drain port, 9 is an elevator duct, 10 is a floor of the uppermost floor, and 11 is a floor of the lowermost floor. The cooling device main body 2 attached to the elevator car 1 generates condensed water in its heat exchanger during operation. The condensed water is stored in the storage tank 4 through the downcomer pipe 3, and then discharged through the drain pipe 7 through the hose 5 and the water receiver 6 to the outside of the building through the drainage port 8. Since the elevator car 1 moves up and down in the elevator duct 9, when the car 1 is at the upper position of the elevator duct 9 as shown by the solid line, the condensed water is as described above, the condensation pipe 3 and the storage tank 4. After passing through the hose 5, the water receiver 6 and the drainage pipe 7, the water is discharged to the outside of the building through the drainage port 8 buried in the building.
However, when the car 1 is at the lower position of the elevator duct 9, the condensed water is always stored in the curved portion 5a of the hose as shown by the one-dot chain line in FIG. 3, and the car 1 is condensed in the hose 5. The inside of the duct 9 is moved up and down while the water is stored. When the car 1 rises and the water level of the condensed water in the hose 5 rises further than the position of the water receiver 6, the condensed water in the hose 5 passes through the water receiver 6 and the drain pipe 7 and is discharged from the drainage port 8 to the outside of the building. Will be done. That is, if the elevator car 1 moves up and down appropriately, the condensed water generated in the cooling device is automatically drained every time the car 1 moves up to the upper position.

In the drainage mechanism of the condensed water, the hose 5
If the storage capacity of 1 is allowed to have a certain margin with respect to the generated amount of condensed water, there will be no problem when the elevator car 1 is smoothly moving up and down. However, if the car 1 waits in the lower position for a long time or repeats raising and lowering only in the lower position,
Condensed water generated in the air conditioner may not be completely drained and may overflow. In order to avoid such a situation, a pump and a water level meter are provided in the condensed water storage tank, and when the amount of the stored water in the hose 5 increases and reaches a predetermined water level in the storage tank, the water level gauge operates to drive the pump to drain water. There are things I tried to do.

FIG. 4 is a block diagram showing an example thereof disclosed in Japanese Patent Application Laid-Open No. 3-42486, in which 1 to 11 are the same parts as the conventional device, 12 is a storage tank, 13 is a pump, and 14
Is a water level gauge, and 15 is a discharge pipe of the pump. When the water level of the condensed water stored in the hose 5 is equal to or lower than a predetermined value, the condensed water in the storage tank 12 is drained from the drain port 8 via the check valve 16, the hose 5, the water receiver 6, and the drain pipe 7. However, when the car 1 is operated only in the lower position to increase the condensed water and the water level in the storage tank 12 rises, the water level gauge 14 functions to operate the pump 13, so that the condensation in the storage tank 12 is performed. Water is the discharge pipe 15,
The water is drained from the drain port 8 through the hose 5, the water receiver 6 and the drain pipe 7. If the water level in the storage tank 12 drops, the pump 13
Then, the condensed water in the storage tank 12 returns to the state of being drained from the drain port 8 via the check valve 16, the hose 5, the water receiver 6, and the drain pipe 7 as described above.

[0005]

By the way, the drainage of the condensed water generated in the conventional cooling device in the elevator is as shown in FIG.
As shown in FIG. 5, the hose 5 moving together with the car 1 is moved up and down. Therefore, if the car 1 is waiting in the lower position for a long time or is being operated only in the lower position, the condensed water may overflow, so it is necessary to raise the car to the upper position from time to time and the overflow may occur. In preparation for this, it is necessary to consider moisture protection measures for peripheral devices. In addition, in order to drain all the condensed water to the outside of the building, the hose 5, water receiver 6, drain pipe 7
In addition, the drainage port 8 and the like are required, and the construction cost increases accordingly. Further, when an air conditioner is additionally installed in an existing elevator, burying work for the above-mentioned components, especially the drainage port 8 buried in the building, requires a great deal of labor and cost. The method of using a pump for avoiding the overflow of condensed water shown in FIG. 4 is also effective in preventing the overflow of condensed water, but the fact that a hose 5 or less is required is the same as the above-mentioned conventional example. Therefore, the construction cost is the same as the above-mentioned conventional example.

The present invention has been made in order to solve the above-mentioned problems of the condensed water drainage system for the elevator car air conditioner, and does not require a drainage port buried in the building and also allows a condensed water to flow out. It is an object of the present invention to provide a cooling system for an elevator car which does not require a drainage pipe or the like, and therefore has a low construction cost.

[0007]

In order to achieve the above object, an elevator car air conditioner according to the present invention has a water level gauge and condensed water in a storage tank for storing condensed water generated in the air conditioner. Equipped with atomization or evaporation means.

[0008]

The condensed water generated in the cooling device is stored in the storage tank. When the amount of condensed water increases and the water level in the storage tank reaches a predetermined value, the water level gauge functions to operate the atomizing or evaporation means to atomize and evaporate the condensed water. No hoses, drains or drains buried in the building are needed.

When the condensed water stored in the storage tank 20 increases and the water surface 23 thereof rises and reaches a predetermined position, the water level gauge 21 functions to operate the atomizing device 22. As a result, the condensed water stored in the storage tank 20 is atomized into fine water droplets 24, which are discharged into the elevator duct 9 through the opening 20a of the storage tank, and eventually evaporated in the elevator duct 9 to the atmosphere. Spread. When the water surface 23 in the storage tank 20 drops due to atomization, the water level gauge 21 operates and the atomization device 22 is stopped. In this way, the water level 23 in the storage tank 20 is automatically kept substantially constant by the operation of the water level gauge 21 and the atomizing device 22, so that there is no possibility that condensed water overflows and wets elevator parts and the like. .

Embodiment 2 In the above embodiment, the condensed water in the storage tank 20 is atomized by the atomizing device utilizing ultrasonic waves. However, instead of the atomizing device, for example, an electric heater or an infrared heater is arranged. However, the condensed water in the storage tank 20 may be evaporated in conjunction with the water level gauge. The evaporated condensed water diffuses into the atmosphere as it is.

Example 3 Further, instead of the above-mentioned atomizing device using ultrasonic waves, condensed water is put into a moisture permeable membrane tube capable of passing water vapor, and hot air is applied to the moisture permeable membrane tube to evaporate the condensed water. You may allow it.
