DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having therein a refrigeration cycle including an evaporator, a condenser and a compressor, and a blower, wherein drain water condensed by the evaporator is evaporated by the condenser. Things.

[0002]

2. Description of the Related Art Conventionally, drain water generated by being condensed in an evaporator of an air conditioner is stored in a drain tank provided in the air conditioner, and is discarded to the outside at regular intervals or when the water becomes full. Drain tank system, a hose connected to a drain pan that receives drain water, and a drain hose system that discharges directly to the outside. A condenser is arranged below the evaporator, and the treatment is performed by a direct evaporation method in which drain water is introduced into a condenser for direct evaporation and the like.

[0003]

Among the drain water treatment methods in the conventional air conditioners, the drain tank method requires a lot of trouble to manage the level of the drain water in the drain tank and to carry the drain tank. In addition, the drain hose method requires a water distribution system to discharge drain water through a hose, and the indirect evaporation method requires an additional pump to pump drain water. In the evaporation method, if it is difficult to uniformly introduce drain water from the evaporator to the condenser, or if the evaporator and the condenser are integrally arranged vertically, the evaporator and the condenser However, there is a problem that the heat exchange is directly performed between the heat exchangers and the cooling capacity cannot be sufficiently exhibited.

The present invention has been made in view of the above-mentioned problems of the conventional system for treating drain water in an air conditioner, and condenses drain water from the evaporator while interrupting heat exchange between the evaporator and the condenser. It is an object of the present invention to provide an air conditioner that can be uniformly introduced into a vessel.

[0005]

In order to achieve the above-mentioned object, an air conditioner according to the present invention includes therein a refrigeration cycle including an evaporator, a condenser and a compressor, and a blower, and drain water condensed in the evaporator. In an air conditioner configured to evaporate by a condenser, the condenser is arranged at a predetermined interval below the evaporator.

In this air conditioner, heat exchange between the evaporator and the condenser is blocked by an air layer by disposing the condenser at a predetermined interval below the evaporator, Water is introduced uniformly from the evaporator to the condenser located directly below.

[0007] In this case, the distance between the evaporator and the condenser can be set so that the drain water generated in the evaporator does not become a water drop that falls naturally.

Thus, the drain water generated in the evaporator can be uniformly introduced into the condenser before becoming large water droplets, and the drain water can be reliably evaporated.

Further, the interval between the fins of the condenser can be set to be different from the interval between the fins of the evaporator.

[0010] Thus, the evaporation capacity of the drain water can be adjusted, and an air conditioner suitable for the environment in which the air conditioner is installed can be easily obtained.

Further, the blower for the evaporator and the blower for the condenser can be driven by a common motor.

Thus, the manufacturing cost of the air conditioner can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an air conditioner according to the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the air conditioner of the present invention. In this air conditioner, a drain tank 2 and a compressor 3 are detachably installed at a lower portion, and an evaporator 4 and a condenser 5 are vertically arranged and arranged above the drain tank 2. Blower 10 and condenser blower 1
1 is provided.

A drain pan 6 is disposed on the drain tank 2 at a position below the condenser 5 and receives drain water generated by the evaporator 4 which has fallen due to the fins of the condenser 5 being unable to evaporate. It is introduced into the tank 2.

The evaporator 4 and the condenser 5 are connected to the body frame 1
And the air (outside air) is sucked into the main body frame 1 through the evaporator 4 and the condenser 5 by the evaporator blower 10 and the condenser blower 11.

Evaporator blower 10 and condenser blower 1
1 is covered by casings 10K and 11K, respectively. The air cooled by heat exchange in the evaporator 4 is cooled by the casing 1 provided with the evaporator blower 10.
From 0K, it is used for cooling through a discharge port 8a and a ventilation duct (not shown). On the other hand, heat is exchanged in the condenser 5,
The heated air is discharged from the casing 11K, in which the blower 11 for the condenser is disposed, to the outside via the discharge port 8b and a blow duct (not shown). Thus, the evaporator 4
The air (cold air) cooled by the air and the air (warm air) heated by the condenser 5 are separated and separately discharged.

In this embodiment, the blower 10 for the evaporator and the blower 11 for the condenser are simultaneously driven by one double-shaft motor 9 disposed behind the condenser 5. . Thus, the manufacturing cost of the air conditioner can be reduced, and the air cooled by the heat exchange in the evaporator 4 can be prevented from being heated by the heat generated by the motor. It should be noted that the evaporator blower 10 and the condenser blower 11 may be configured to be driven by separate motors.

As shown in FIG. 3A, the evaporator 4 and the condenser 5 have a predetermined distance d, specifically, d = 0.1 to 0.1.
By arranging 1.0 mm, preferably d = 0.2 to 0.5 mm, heat exchange between the evaporator 4 and the condenser 5 is blocked by an air layer. by the way,
If the distance d between the evaporator 4 and the condenser 5 is set to be large as shown in FIG. 3B, the drain water condensed in the fins of the evaporator 4 is directly changed by the surface tension of the water. Without being introduced into the evaporator 4, they gather in the horizontal direction below the evaporator 4 to form large water droplets and fall toward the condenser 5,
It cannot be introduced uniformly into the condenser 5. Therefore, by setting the distance d between the evaporator 4 and the condenser 5 to the above-mentioned predetermined distance d, the drain water condensed in the fins of the evaporator 4 is moved downward by the action of the surface tension of the water. Before gathering horizontally in
At that position, it immediately contacts the fins of the condenser 5 so that it is uniformly introduced into the condenser 5.

In this case, the distance d4 between the fins of the evaporator 4 and the distance d5 between the fins of the condenser 5 may be set to be equal. Thereby, the ratio of the amount of drain water generated in the evaporator 4 to the amount of drain water that can be evaporated in the condenser 5, that is, the evaporation capacity can be adjusted, thereby reducing the environment in which the air conditioner is installed. A suitable air conditioner can be easily obtained. In an air conditioner used in an environment with a lot of dust, the fins of the condenser 5 are easily clogged by the dust. Therefore, the interval d5 between the fins is set wide, and the drain water flows to the drain pan 6 below. It is also possible.

Next, the operation of the air conditioner will be described. When this air conditioner is installed in a factory or a work place and starts operation, air (outside air) is sucked into the main body frame 1 through the evaporator 4 and the condenser 5. The sucked air undergoes heat exchange in the evaporator 4, and is used for cooling from the casing 10K in which the blower for the evaporator 10 is disposed, through the discharge port 8a and the air duct (not shown). On the other hand, the air that has undergone heat exchange in the condenser 5 and is heated is discharged from the casing 11K, in which the blower 11 for the condenser is disposed, to the outside through the discharge port 8b and the blower duct (not shown).

At this time, the drain water condensed in the fins of the evaporator 4 is immediately gathered at the position before the water collects in the horizontal direction below the evaporator 4 under the action of the surface tension of the water to form large water droplets. In contact with the fins 5, the fins are uniformly introduced into the condenser 5, and evaporate while falling down the fins of the condenser 5. The drain water that has fallen without being evaporated along the fins of the condenser 5 is introduced into the drain tank 2 via the drain pan 6.

Further, since the evaporator 4 and the condenser 5 are arranged at a predetermined distance d, heat exchange between the evaporator 4 and the condenser 5 is blocked by this air layer. ,
The desired cooling capacity can be fully exhibited.

[0024]

According to the air conditioner of the present invention, heat exchange between the evaporator and the condenser is blocked by the air layer by disposing the condenser at a predetermined interval below the evaporator. As a result, the cooling capacity can be sufficiently exhibited, and the drain water can be uniformly introduced from the evaporator to the condenser disposed immediately below the evaporator, so that the drain water can be surely evaporated.

Also, by setting the distance between the evaporator and the condenser so that the drain water generated in the evaporator does not become a water drop that drops naturally, the drain water generated in the evaporator is reduced.
Before the water droplets become large, they can be uniformly introduced into the condenser, and the drain water can be more reliably evaporated.

Also, by setting the interval between the fins of the condenser to be different from the interval between the fins of the evaporator, the evaporation capacity of the drain water can be adjusted, and the air conditioning suitable for the environment in which the air conditioner is installed. Machine can be obtained easily.

[0027] Further, by configuring the blower for the evaporator and the blower for the condenser to be driven by a common motor,
The manufacturing cost of the air conditioner can be reduced.
