BACKGROUND OF THE INVENTION
The present invention relates to an elevator apparatus with an air conditioner.
[0002]
[Prior art]
12 and 13 show a conventional elevator apparatus disclosed in, for example, Japanese Utility Model Laid-Open No. 60-61266. In the figure, reference numeral 1 denotes a passenger cabin which is an elevator cab where passengers get on and off, and a passenger cabin is supported by a car floor frame 1c attached to a lower beam 1b of the car frame 1a through vibration-proof rubber. 1d is a passenger cabin door, and 1e is a doorway door on the building side. 2 is a ceiling surface in the passenger cabin 1, and 3 is a floor surface of the passenger cabin 1. 4 is a main rope that suspends the passenger cabin 1 and moves it up and down and holds it by a lifting device (not shown), 5 is a hoistway, 5a is a drain receiver provided at the bottom of the pit below the hoistway 5, and 6 is a passenger. It is an air conditioner mounted on the upper part of the chamber 1, and includes a compressor 7, a condenser 8, an evaporator 10, a refrigerant throttle device 11, a refrigerant pipe 12, a condenser fan 8a, an evaporator fan 10a, and an evaporator drain receptacle 10b. It is configured. 2a is an air outlet of the air conditioner 6 provided on the ceiling surface 2, and 2b is an air inlet of the air conditioner 6 provided on the ceiling surface 2 of the passenger cabin. A tank 13 is suspended and fixed by a bracket 13a below the car floor frame 1c, and is connected to a drain pipe 13c having an electromagnetic valve 13d at the lower part via an evaporator drain receiver 10b and a drain pipe 13b. 14 is a limit switch for detecting the load of the passenger compartment 1 attached to the car floor frame 1c, and 14a is a cam member attached to the lower part of the passenger compartment.
[0003]
Next, the operation will be described.
Passengers get in and out of a passenger cabin 1 that is suspended by a main rope 4 and moved up and down by a lifting device such as a hoisting machine (not shown) and stopped at a required floor in a hoistway 5 partitioned from a building or the like. As is well known, the passenger cabin 1 has three walls, and a door that opens and closes is provided on one surface, and becomes a closed moving space during movement to each floor.
When the passenger cabin 1 of such an elevator moves with a passenger on a high-rise building in summer, for example, the room temperature of the passenger cabin 1 rises due to the temperature and the passenger's body temperature, so the air conditioner 6 installed in the upper part To cool the passenger cabin.
[0004]
At this time, in the refrigerant circuit of the air conditioner 6, the refrigerant liquid is blown out from the air outlet 2a into the passenger room as cold air by exchanging heat in the passenger room air sucked from the intake port 2b by the evaporator fan 10a. Cool the air. The surface of the evaporator 10 is dewed by heat exchange. The condensed water drops downward and temporarily accumulates as drain water in the evaporator drain receptacle 10b, and then flows down into the tank 13 below by the drain pipe 13b. It is done. A large amount of drain water is generated especially during the rainy season.
Since the tank 13 in which the drain water is accumulated is configured to be detected together with the weight of the passenger, if the sum of the weights of both of them becomes an overload, the cam member 14a is limited by the lowering of the passenger cabin. An elevator control circuit (not shown) is activated by contacting the switch 14 and issues an alarm, or the refrigerant operation of the air conditioner 6 is stopped and only the air fan 8a is operated to circulate only air. The chamber 1 is lowered to the lowest floor and the drain water in the tank is discharged to the drain receiver 5a.

Next, the operation will be described. When a passenger enters the passenger compartment 1, the object detection device 16 arranged on the ceiling surface 2 always transmits a radio wave downward and is reflected again by the floor surface 3 so that it is received again. When the radio wave hits the passenger, it is reflected or reflected in a different direction, so the number of passengers is detected due to the time difference until these receptions or changes such as inability to receive, and if this detection value exceeds a predetermined value, In response to the detection command, the air conditioner 6 is activated, and the air in the passenger compartment 1 is introduced into the air conditioner 6 from the air inlet 2b, is heat-exchanged and becomes cold air, and is blown out from the air outlet 2a into the passenger compartment.
