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 the basket to the bottom floor and drain the condensed water there. From now on, we will call this the electric valve type. First, regarding Utility Model Publication No. 52-6133, 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 provide harmony such as cold air inside the car 4. An air conditioner that sends air, 6 a conduit that guides condensed water generated from the heat exchanger of the air conditioner 5 to the outside of the machine, 7 provided at the bottom of the basket 4 to store condensed water led from the conduit 6 8 is a water receptacle provided on the hoistway wall 3 at a position approximately halfway between the uppermost floor 1 and the lowermost floor 2, and 9 is a conduit connecting the lower part of the storage tank 7 and the water receptacle 8. As also shown in FIG. The other end of the flexible water w11 is connected to the water receptacle 8, and the flexible water pipe 11 is suspended in the hoistway and has a U-shaped curved portion 11a formed at its 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 drain pipe 12 is provided at the bottom of the hoistway. The hose type condensed water drainage device configured as above is
When the air conditioner 5 is operated for cooling or dehumidifying, condensed water 14 generated from the heat exchanger is led to the conduit 6 and stored in the storage tank 7. Condensed water 14 in storage tank 7
When the water level reaches a position 15 at the upper end of the outlet pipe 10, the upper part of the condensed water 14 flows into the flexible water pipe 11 through the outlet pipe 10 and is stored in the curved part 11a. Car 4 is the top shown in Figure 2 lol! 1, etc., the upper part of the condensed water 14 in the curved part 11a reaches the water receiver 8 and crosses over it, and is led to the lower water receiver 13 through the drain pipe 12 and discharged to the outside of the hoistway. Moreover, if the car 4 is repeatedly raised and lowered on the lower floor without going to the upper floor while the condensed water 14 is stored in the curved portion 11a, on the lowest floor 2 shown in FIG.
The upper surface of the condensed water 14 in the curved portion 11a may exceed the position 15 of the upper end of the outlet pipe 10 in the storage tank 7, and in this case, the condensed water 14 flows back into the storage tank 7 and is stored. Next, regarding Utility Model Publication No. 52-37952, an electric valve type condensed water drainage device 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 and 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. 20 is a zero water level detector that opens when there is no more condensed water 14 in the storage tank 7; 21 is also a condensed water 14;
22 is the return command relay, 22a and 22b are its normally open contacts, 23 is the return circuit that returns the car 4 to the bottom floor, and 24 is the heel 4, 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. In the electric valve-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 to the conduit 6 and stored in the storage tank 7. The main water level detection contact 20 is closed. When the condensed water 14 becomes full, the full water level detection contact 21 closes, the return command relay 22 is energized by the (+)-20-21-22-(-) circuit, and by opening the contact 22b, The return circuit 23 is activated and the car 4 is driven to the lowest floor. When the car 4 reaches the bottom floor, the car position contact 24 and the traveling relay contact 25 are closed, and the (+)-22
In the circuit b-24-25-26-(-), the drain command relay 26 is energized, the contact 26a is closed, and the contact 26b is opened. 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, falls into the drainage device 17, and is discharged to the outside of the hoistway. This draining operation continues until the main water level detection contact 20 opens. By opening this contact point 26b, the operating circuit 27 is disconnected from the power supply (+) and (-).
Car 4 does not respond to floor calls. When drainage from the storage tank 7 is completed and the main 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 driving circuit 27 returns to the power supply (+) and (-).

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, and it is possible to operate air conditioners without using expensive water level detectors, cage storage tanks, etc., and without degrading service to users. An object of the present invention is to provide a condensed water drainage device for an elevator air conditioner that drains condensed water.

(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 outlet, conventional storage tanks 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, the storage tank is used up, so the whistling sound is no longer generated, which does not cause discomfort to the people inside the car.

5 is an air conditioner; 11 is a flexible water pipe that hangs down from the condensed water outlet of the air conditioner to the lower part of the hoistway; 30 is provided at the lower part of the hoistway, and as the car 4 moves up and down, the water pipe is automatically connected by a force such as a spring This is an automatic woodwind winding machine that winds up windings. The condensed water drainage device of this embodiment has a flexible water pipe hanging directly from the condensed water drain port of the air conditioner 5 to the lower part of the hoistway, and the water pipe is connected to the lower part of the hoistway by the force of a spring or the like as the car 4 moves up and down. The condensed water 14 is automatically wound up by an automatic water tube winding machine driven by a water tube, so that the condensed water 14 can be drained at all times. [Effects of the Invention] As explained above, in the condensed water drainage device for an elevator air conditioner according to the present invention, a flexible wood pipe, one end of which is connected to the condensed water discharge port of the air conditioner, is installed at the bottom of the hoistway. The automatic water tube winding machine that has been installed corresponds to the lifting and lowering of the cage.
Since the length in the vertical direction can be expanded and contracted, the condensed water generated from the air conditioner does not have to be stored in the storage tank installed at the bottom of the car, as in the case of conventional systems, so that the condensed water can be drained at all times. This has the effect that the car is not forced to be summoned for drainage of condensed water, and service for elevator users is not degraded. Therefore, according to this embodiment, as in the conventional hose-type condensed water drainage device, the sound is generated by the suction of air in the storage tank, which causes discomfort to the people inside the car. This has the effect of improving riding comfort by eliminating this problem. In addition, unlike the electric valve type, there is no need for an expensive water level detector installed in the storage tank or a signal path for transmitting the output signal of this water level detector to the elevator control panel, making it a simple and inexpensive device. There are benefits to be gained. In addition, in the above-mentioned embodiment, a case was explained in which there is only one flexible water pipe hanging from the condensed water drain port to the lower part of the hoistway.
Of course, it is also possible to use a plurality of flexible woodwinds.
