Field of the Invention The present invention relates to a so-called integrated air conditioner in which an indoor heat exchanger and an outdoor heat exchanger are housed in a main body, and to an improvement in a structure for treating drain water generated during cooling operation. About.

[0002]

2. Description of the Related Art For example, an air conditioner for cooling or heating the inside of an elevator is mounted on a gondola (hereinafter, simply referred to as an elevator) constituting an elevator apparatus. This air conditioner uses a refrigeration cycle,
A so-called integral type having an indoor heat exchanger and an outdoor heat exchanger in the main body is used.

[0003] During the cooling operation, the dew point of the air that is heat-exchanged in the indoor heat exchanger is reduced, and the water condenses and becomes dripped as drain water. A drain pan is arranged below the indoor heat exchanger, and all drain water is collected. The drain water is guided to the outdoor heat exchanger side and is scooped up. By spraying water on the heat exchanger, the heat exchange efficiency is improved and the drain water is evaporated.

Specifically, a slinger ring is attached to the outer periphery of the fan of the outdoor blower, and a part thereof is immersed in drain water. When the outdoor blower is driven to rotate, the fan blows outside air to the outdoor heat exchanger, and the ring lifts up the drain water. The drain water becomes water droplets, mixes with the outside air, and falls to the outdoor heat exchanger.

[0005] Alternatively, a dedicated scraping member may be provided in parallel with a normal type outdoor blower. This has a scraping portion along a peripheral edge of a rotating plate connected to a motor, and rotates the rotating plate to scrape water in a centrifugal direction. At the same time, the drain water that has been blown out by the outdoor blower is put on the wind and sent to the outdoor heat exchanger.

In addition, there is no difference in blowing outside air to the outdoor heat exchanger.

However, the outdoor heat exchanger has a configuration in which a large number of fins are arranged with a small gap therebetween, and the fins are resisted by blowing strong external wind. In addition, the wind hits especially the blower facing surface of the outdoor heat exchanger,
The periphery was uneven, such as weakening, and wind and water noises were generated, causing noise.

In order to reduce these noises, an outdoor blower is arranged on the leeward side of the outdoor heat exchanger, and the outside air sucked into the main body is directly guided to the outdoor heat exchanger, and then the external air is blown through the blower. It is good to discharge to.

However, considering the drain water evaporation treatment, the outdoor heat exchanger is located on the suction side of the outdoor blower and is not present on the discharge side, so that the slinger or the scraping member lifts the drain. All the water is discharged to the outside without being caught in the outdoor heat exchanger, and the drain water evaporating process becomes impossible.

[0010] The present invention has been made in view of the above circumstances, and an object thereof is an integrated type in which an indoor heat exchanger and an outdoor heat exchanger are housed and arranged in a main body.
Air conditioning that reduces noise such as wind noise and improves the efficiency of drain water evaporation, assuming that the drain water generated in the indoor heat exchanger is scattered to the outdoor heat exchanger for evaporation. Is to offer a machine.

The air conditioner thus configured is configured such that when a cooling operation is instructed, the indoor blower 7 is driven, and the air in the elevator A flows from the indoor suction port 4 to the indoor unit 3A of the main body 1. And is guided to the indoor heat exchanger 6 to perform heat exchange, and is changed to cool air and blown out from the indoor outlet 5. In this way, the cool air is supplied into the elevator A to cool the room.

By instructing the heating operation, the indoor blower 7 is driven, and the air in the elevator A is sucked into the indoor side unit 3A of the main body from the indoor suction port 4 and is guided to the indoor heat exchanger 6 for heat. After the replacement, the air is changed into warm air and is blown out from the indoor outlet 5. In this way, warm air is supplied into the elevator A to heat the room.

In any of the cooling and heating operations, the outdoor blower 13 is driven in the outdoor unit 3B.
Outside air inlets 10a, 10b, 1 of both side plates 1b, 1c
From 0c, outside air is sucked into the outdoor unit, guided to the outdoor heat exchanger 12 to perform heat exchange, and is blown out from the outlet 11 of the back plate 1d to the outside.

The scraping member 15 operates during a cooling operation. That is, the moisture contained in the air that has exchanged heat with the indoor heat exchanger 6 is condensed and changes into drain water and flows down to the drain pan P. The drain water flows to the outdoor unit 3B, and immerses a part of the periphery of the rotary plate 17 of the scraping member 15.

The rotating plate 17 is driven to rotate and lifts the drain water in the centrifugal direction Ea, so that the drain water scatters in the same direction as water droplets or mist. On the other hand, the outdoor blower 13
Is driven to guide the outside air from the outside air suction ports 10a, 10b, 10c to the outdoor heat exchanger 12, so that water droplets or mist-like drain water mixes with the outside air and falls on the outdoor heat exchanger 12.

At the time of cooling, the refrigerant is condensed in the outdoor heat exchanger 12 to release heat of condensation, so that the drain water that has begun to absorb the heat of condensation and evaporates immediately. Therefore, the drain water is promptly evaporated, and the heat exchange efficiency of the outdoor heat exchanger 12 is improved.

In this air conditioner, the outdoor blower 1
3 is disposed on the rear side, and the outdoor heat exchanger 12 is disposed on the suction side, which is the leeward side, so that wind pressure does not apply to the surface of the outdoor heat exchanger, and a smooth wind flow can be obtained. Low generation of sound.

Since the scraping member 15 is located on the windward side of the outdoor heat exchanger 12 in the guide path of the outside air to be sucked in, the flow of air becomes uniform and the scraped-up drain water is evenly distributed. Splashed. Then, the heat can be efficiently descended to the outdoor heat exchanger 12, whereby the heat exchange efficiency of the outdoor heat exchanger can be further increased, and the drain water evaporation process can be performed more reliably.

Compared to a conventional configuration in which an outdoor blower is arranged on the windward side of an outdoor heat exchanger and blows air toward the outdoor heat exchanger, the operation sound and the drain water scooping sound are generated because the air flow is quieter. And the operating noise is not bothersome even near the air conditioner.

[0053] The outdoor heat exchanger 12 is a heat exchanger of the so-called finned tube type, continuously provided a straight extending portions 12A ₂ along the curved portion 12A ₁ and the side plate 1c on one end, Since the outside air suction port 10b is provided opposite to the extending portion, even if the scraped-up drain water scatters in the direction of the side plate 1c, it directly hits the heat exchanger fins and the outside air suction port 10b.
b can be prevented from going outside, and the heat exchange efficiency is improved.

Here, the outdoor heat exchanger 12 has two rows of heat exchangers 12A and 12B arranged in front and rear, and the bent portions 12A ₁ and 12B ₁ and the extended portions 12A ₂ and 12B ₂ are provided at one end of each row. And the outside air inlets 10b and 10c are provided on the side surfaces facing the respective extending portions, so that the heat exchange efficiency of the outdoor heat exchanger 12 can be further improved, and the air conditioner as a housing is provided. The main body 1 can be made compact.

[0055] scraping up because placed so as to face the centrifugal direction Ea of the rotating plate 17 to the curved portion 12A ₁ of the outdoor heat exchanger 12A constituting the member 15, the scattering direction of the drain water by the rotating plate and the outdoor heat exchanger Is different from the surface direction of the fins, and the scattered drain water is stopped at the fin surface to prevent leakage to the outside air suction port 10b.

The outdoor heat exchanger ₁ is provided with an inclined portion 1e1 on the main body top plate 1e so that drain water that is scraped up and adheres to the main plate 1e flows down.
Since it is guided to fall on the upper surface, the evaporating action of the drain water can be promoted, and the heat exchange efficiency of the outdoor heat exchanger is further improved.

[0057] provided with a guide member 18 in the top plate inclined portion 1e _1, middle drop outdoor heat exchanger receives the drain water 12
Since the liquid is guided to the upper surface, the drain water evaporation action can be further promoted, and the heat exchange efficiency can be increased.

Since the air conditioner main body 1 partitioned into the indoor unit 3A and the outdoor unit 3B is arranged on the ceiling a of the elevator A, the distance from the passenger in the elevator A to the air conditioner main body 1 is increased. The driving noise can be reduced under the condition that the distance is very short, and an air-conditioned indoor space can be obtained without impairing the comfort due to the noise.

Although the above-described air conditioner is provided for air-conditioning in an elevator room, the present invention is not limited to this. It may be used.
