DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a built-in humidifier.

[0002]

2. Description of the Related Art Generally, in an air conditioner installed in a room, outside air is introduced as necessary to ventilate the room air. An air conditioner for treating outside air, which heat-exchanges outside air introduced into a room to near room temperature in advance in order to increase the temperature, is known.

[0003] Such an air conditioner generally takes in outside air from above the air conditioner by a duct, and similarly blows the air after heat exchange into the room from above. However, in this case, the flow of the outside air is reversed by 360 ° inside the machine, so that the ventilation resistance inside the machine is constantly increased. For this reason, it is desirable that the air sucked from above is blown out from an air outlet formed in a lower portion, and a duct is connected to the air outlet to guide the air upward, so that the flow of the outside air is made linear in the machine. In this case, a blower and a heat exchanger are arranged in this order between the upper suction port and the lower discharge port, in order from the upper suction port, and the blower port is located on the side of the main body. It is conceivable to provide a panel on one side in the direction, to which a duct for blowing is connected.

On the other hand, in a conventional air conditioner, as disclosed in Japanese Utility Model Publication No. Sho 56-47458, air is taken in from above and passed through a heat exchanger, and then blown by a humidifier. A device that humidifies air and blows air is disclosed. This prior art humidifier humidifies by generating steam by heating.

[0005]

However, water is supplied from the upper end portions of the innumerable fins so that the water flows along the fins, and a natural vaporizing method for imparting humidity to the air passing through the fins is provided. In such a humidifier, water may not fall along the fins and may fall on the bottom surface of the main body. In particular, when dirt or dust adheres to the fin, such a drop is likely to occur.

In such a case, it is conceivable to extend the drain pan of the heat exchanger to below the fins, but this would impede the ventilation path and is not practical. Also, if the drain pan of the heat exchanger is formed widely on the entire bottom surface of the main body to receive the droplets of the humidifier, the dew condensation water of the heat exchanger always falls on the bottom surface, and the heat exchanger There is an inconvenience that dew condensation water falling from the water always jumps. Such splashing of water causes noise.

Accordingly, an object of the present invention is to provide an air conditioner that can prevent water leakage due to water drops dropped from a humidifier.

[0009]

[0010]

In the air conditioner of the present invention, the air taken into the main body from the air inlet formed on the upper portion is blown out from the blower of the blower toward the heat exchanger and passed through the heat exchanger. The wind is subsequently humidified by a humidifier and then blown from an outlet formed at a lower portion.

In the case where the drain water falls from the humidifier due to the adhesion of dust or other causes, the dropped drain water is received by the drain pan arranged on the bottom surface of the main body.
Water leakage from the main body is prevented.

Note that a ceiling panel 3e is attached to the upper surface of the main body 3, and a bottom panel 3f is attached to the bottom surface.

A rectangular air intake 13 is formed in the ceiling panel 3e substantially at the center thereof, and an outside air intake duct 15 is connected to the air intake 13 so that outside air can be taken in from above the main body 3. ing. On the lower surface of the air intake 13,
An air filter 16 is attached to perform primary cleaning of the air taken in.

On one side panel 3b (right panel in FIG. 1), an outlet 17 for blowing out the air after the heat exchange is formed. The air after replacement is guided upward.

In the main body 3, a blower 5, an air purifying filter 7, a heat exchanger 9, and a humidifier 11 attached to the heat exchanger 9 are arranged in this order from above.

The blower 5 is arranged at the center of the upper stage in the main body, that is, the center line 19a of the blower port 19 substantially coincides with the center line of the main body 3 in the lateral direction (longitudinal direction). And
By driving the blower 5, air is taken in from an air intake 13 formed in the ceiling panel 3 e and blown downward from the blower opening 19. The blower 5 is a centrifugal fan.

An air purifying filter 7 as a secondary filter is arranged at a lower stage of the blower 5 to purify the blown air. This air purifying filter 7
Are arranged on the left and right with respect to the center line 19a of the air outlet 19, and are configured to be freely exchangeable by being pulled out from the main body. Note that a so-called medium performance filter is used as the air cleaning filter.

In the lower stage of the air purifying filter 7, a heat exchanger 9 is arranged in a strut so as to cross the inside of the main body 3, and efficiently exchanges heat with the passing air.

The heat exchanger 9 is moved to the outlet 17 side, and the center line 9a in the lateral direction of the heat exchanger 9 is located closer to the outlet 17 by a distance S than the center line 19a of the blower opening of the blower. I have. In this way, by moving the heat exchanger 9 to the outlet 17 side, it is possible to prevent the air flow passing through the heat exchanger from being biased in accordance with the ventilation path, and to uniformly and entirely cover the heat exchanger. Since it can be flowed, the heat exchanger can be used efficiently. In addition, heat exchanger 9
Is provided with a drain pan 10 at its lower end for receiving dew water so as to derive dew during cooling operation.

One side of the heat exchanger 9 is arranged close to the side panel 3b, and forms a space 21 on the other side.
