に接続される。これで通常運転に復帰する。In recent years, there has been a trend for cars to be equipped with air conditioners as part of efforts to improve services for elevator users. In this case, treatment of waste water from the air conditioner becomes a problem. For example, in the elevator with air conditioner shown in Utility Model Publication No. 52-6133, a water pipe is suspended between the car and the hoistway.
It has been proposed that when the car travels to an intermediate floor or above, the water level in the elevator or storage tank rises and the water is drained. From now on, this will be called the hose method. In addition, in the elevator with an air conditioner shown in Utility Model Publication No. 52-37952, condensed water generated from the air conditioner is stored in a storage tank, and when it is detected that the water level exceeds a set level, the It has been proposed to bring Nikato to the bottom floor and drain condensed water there. From now on, we will call this the electric valve type. First, regarding Utility Model Publication No. 53-6133, Figures 2 to 4
This will be explained using figures. In Figures 2 and 3, 1 and 2 are the top and bottom floors, 3 is the hoistway wall, 4 is the elevator car, and 5 is mounted on the top of the car 4 to blow cold air into the car 4. 6 is a conduit for guiding condensed water generated from the heat exchanger of the air conditioner 5 to the outside of the machine; 7 is a conduit provided at the bottom of the basket 4 and condensed water guided from the conduit 6; 8 is a water receptacle provided approximately halfway between the top floor 1 and the bottom floor 2 of the hoistway wall 3, and 9 is a conduit connecting the lower part of the storage tank 7 and the water receptacle 8. be. As shown in FIG. 4, this pipe line 9 has one end part of a flexible water pipe 11 connected to the outside part of the storage tank 7 of a vertical outlet pipe 10 that penetrates the bottom of the storage tank 7. After the other end of the water pipe 11 is connected to the water receiver 8, the flexible water pipe 11 is suspended in the hoistway, and a U-shaped groove portion 11a is formed at the lower part. In addition,
In the one shown in FIGS. 2 and 3, a drain pipe 12 whose upper end is connected to the water receiver 8 extends downward along the hoistway wall 3,
A lower water receiver 13 facing the lower end of the drainage [12] is provided at the bottom of the hoistway. In the hose-type condensed water drainage device configured as described above, when the air conditioner 5 is operated for cooling or dehumidification, the condensed water 14 generated from the heat exchanger is guided into the conduit 6 and into the storage tank 7. stored. When the water level of the condensed water 14 in the storage tank 7 reaches the position 15 at the upper end of the outlet pipe 10, the condensed water 14
The upper part of the water flows through the outlet pipe 10 into the flexible water pipe 11,
It is stored in the curved portion 11a. When the car 4 goes to an upper floor such as the top floor 1 shown in FIG. He was ejected out of the hoistway. In addition, if the car 4 repeatedly goes up and down on the lower floor without going to the upper floor while the condensed water 14 is stored in the curved part 11a, the curved part 11a The upper surface of the condensed water 14 inside may exceed the position 15 of the upper end of the outlet pipe 10 within the storage tank 7, and in this case, the condensed water 14 flows back into the storage tank 7 and is stored therein. Next, Utility Model Publication No. 52-37952 will be explained with reference to FIGS. 5 and 6. In the figure, 16 is a drainage mechanism consisting of an electric drainage valve that discharges or stops the condensed water 14 stored in the storage tank 7, and 17 is provided at the bottom of the hoistway, and the condensed water 14 is discharged from the drainage mechanism 16. A discharge device for discharging the waste water 18 to the outside of the hoistway, 20 is a zero water level detection device that is opened when there is no more condensed water 14 in the storage tank 7, and 21 is also a condensed water 14
22 is a return command relay, 22a and 22b are normally open contacts, 23 is a return circuit that returns car 4 to the bottom floor, 24 is the return circuit for car 4 to return to the bottom floor. 25 is the car position contact that closes when it arrives at car 4.
A traveling relay contact that opens while the vehicle is running and closes when it stops, 2
6 is a drainage command relay, 26a is its normally open contact, 26b is also a normally closed contact, 27 is an operating circuit for operating the car 4, (
+) and (-) are DC power supplies. The configuration of this prior art other than the above is similar to that of the hose type condensed water drainage device shown in FIGS. 2 and 3. The electric valve-type condensate water drainage device configured as described above is configured so that when the air conditioner (I5) is in dehumidifying operation, the condensed water 14 generated from the heat exchanger is led to the conduit 6 and stored. It is stored in the tank 7, and the zero water level detection contact 20 is closed.When the condensed water 14 becomes full, the full water level detection contact 21 is closed.
is closed, the return command relay 22 is energized by the (+)-20-21-22-(-) circuit, and the return circuit 23 is operated by closing the contact 22b, and the car 4 is moved to the lowest position. Driven to the floor. When the car 4 reaches the bottom floor, the car position contact 24 and the travel relay contact 25 are closed, and (+)-2
In the circuit 2b-24-25-26-(-), the drain command relay 26 is energized, the contact 26a is closed, and the contact 26b is closed.
is open. When the contact 26a is opened, the drainage mechanism 16 opens, and the condensed water 14 stored in the storage tank 7 becomes drainage water 18, drops to a drainage value M17, and is discharged to the outside of the hoistway. This draining operation continues until the zero water level detection contact 20 opens. By opening this contact point 26b, the operating circuit 27 is disconnected from the power supplies (+) and (-), so the car 4 does not respond to floor calls. When draining of the storage tank 7h) is completed and the zero water level detection contact 20 is opened, the return command relay 22 is deenergized and the contacts 22a and 22b are opened. This deenergizes the drain command relay 26 and contacts 2
6a is opened and the drainage mechanism 16 is closed. In addition, contact point 26
b is closed, and the operating circuit 27 returns to the power supply (+1. (-1
connected to. This will return to normal operation.

凝結水排水装置を提供することを目的とする。However, in the hose-type condensed water drainage device of the conventional elevator air conditioner, there was a risk that condensed water 14 would overflow from the air conditioner 5 if the car did not travel above an intermediate floor for a long time. . In order to avoid this, passengers were semi-forced to be summoned to the upper floors of the top floor, 1st class, which caused problems such as poor service. In addition, the condensed water 14 in the storage tank 7
When the water level drops slightly from position 15 at the upper end of outlet pipe 10,
There is also a problem in that air is sucked in together with the condensed water 14 and a whistle-like sound is generated, which makes people inside the car 4 feel uncomfortable. In the electric valve type, it is necessary to install an expensive water level detector in the storage tank 7, and a signal path is also required to transmit the output signal of this water level detector to the elevator control panel, making the device complicated. It was expensive. In addition, in the above configuration, when the water level detector generates an output signal, the car 4 is semi-forced to the bottom floor 1, contrary to the hose type, and it takes about 5 to 10 minutes to drain the water. Therefore, there were problems similar to those of the hose type, such as the elevator being unable to be used during this period and service to users being significantly degraded. This invention was made to solve the above-mentioned problems.
To provide a condensed water drainage device for an air conditioner for an elevator, which drains condensed water from the air conditioner without overloading and without degrading service to users.

くなるものである。The condensed water drainage device for an elevator air conditioner according to the present invention allows condensed water to be discharged no matter where the car is located, so that it does not cause any inconvenience to elevator users. In addition, since condensed water is discharged directly from the air conditioner's drain outlet, conventional storage tank and electric valve types require a water level detector to detect the water level in the storage tank and the output of this detector. This eliminates the need for a signal path for transmitting signals to the elevator control panel. Furthermore, with the hose type, there is no storage tank, so noises similar to those of rice blowing are no longer generated, and the people inside the car are no longer uncomfortable.

Because the system has a water pipe that expands and contracts, the condensed water generated by the air conditioner does not need to be stored in the storage tank installed at the bottom of the car, as in the case of conventional systems, and the condensed water can be constantly drained from the drainage device. This has the effect that the car is not semi-forcibly called for drainage of condensed water, and service for elevator users is not degraded. According to the embodiment of the present invention, compared to the conventional hose type, since there is no storage tank, no sound is generated due to air intake, and the discomfort of people inside the car due to this noise is avoided. (do,
This has the effect of improving riding comfort. In addition, the electric valve type eliminates the need for an expensive water level detector installed in the storage tank and a signal path for transmitting the output signal of this water level detector to the elevator control panel, resulting in a simple and inexpensive device.
