DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner, and more particularly to a single cross 70 fan, a single heat exchanger, an indoor ventilation section and an outdoor ventilation section. The present invention relates to an integrated air conditioner comprising:

Conventional technology Conventionally, all-in-one air conditioners have had their front side facing indoors.
In addition, the rear side faces the outdoor side, and the indoor air is sucked in from the front side facing the interior and blown into the room from the front side, and the air is sucked in from the rear side facing the outdoors and blown out from the same rear side. It became.

An example of the conventional integrated air conditioner mentioned above will be described below with reference to the drawings.

FIGS. 5 and 6 show an example of a conventional integrated air conditioner.

In FIG. 5, 1 is an integrated air conditioner main body (hereinafter referred to as main body 1), 2 is an indoor heat exchanger, 3 is an indoor blower,
4 is a water tray, 5 is an outdoor heat exchanger, 6 is a compressor, 7 is a drain motor, 8 is a splasher, 9 is a substrate, 10 is a partition plate, and 11 is a back plate.

The operation of the integrated air conditioner configured as described above will be described below.

First, the indoor ventilation circuit will be explained.

In FIG. 6, the indoor air sucked in from the intake port of the front grille 12 of the main body 1 passes through the indoor heat exchanger 2, and is sent into the room from the outlet of the front grille 12 by the indoor blower 3 as shown by arrow A. The air is blown like this. At this time, the drain water generated by condensation in the indoor heat exchanger 2 is collected in a water tray 4 and then transferred to the outdoor heat exchanger 5, as shown in FIG.
The water drips along the fin surface and is stored on the substrate 9.

Next, the outdoor ventilation circuit will be explained.

In FIG. 6, outdoor air sucked in through the intake port of the rear grille 11 of the main body 1 is discharged to the outside of the room through the outlet of the rear grille 11 by the outdoor blower 13 as shown by arrow B.

On the other hand, the drain water stored in the substrate 9 in FIG.
A splasher 8 rotated by a drain motor 7 scrapes up the water and sprinkles it on the outdoor heat exchanger 5, increasing the condensing capacity and evaporating it.

Problems to be Solved by the Invention However, in the above configuration, two blowers, the indoor blower 3 and the outdoor blower 13, are required, and the drain motor 7 for splashing drain water onto the outdoor heat exchanger 5 is required. and a splasher 8 are required, which has the drawbacks of increased cost and increased assembly man-hours. Furthermore, as shown in FIG. 6, there is another drawback in that the indoor air blowing angle X cannot be widened toward the indoor air suction side in order to prevent short circuits.

Means for Solving the Problems In order to solve the above problems, the integrated air conditioner of the present invention has a through hole provided in a partition plate that partitions an indoor ventilation circuit and an outdoor ventilation circuit, and a single cross-fan extending rotatably across the indoor ventilation circuit and the outdoor ventilation circuit through a through hole in the axial direction;
A single heat exchanger having an upper portion disposed in the indoor ventilation circuit and a lower portion disposed in the outdoor ventilation circuit, an indoor suction port provided on the side surface of the main body, and a heat exchanger provided on the front surface of the main body. It is equipped with an indoor side air outlet, an outdoor side intake port and an outdoor side air outlet provided on the back side of the main body.

Effect: With the above-described configuration, the present invention allows indoor air taken in from the indoor intake port provided on the side surface of the main body to pass through the upper part of the heat exchanger disposed in the indoor ventilation circuit for heat exchange. After that, the cross 70-fan can supply air into the room from the indoor air outlet provided on the front of the main unit, while the outside air taken in from the outdoor air inlet provided on the back of the main unit can be supplied to the outdoor ventilation. After the heat is exchanged by passing through the lower part of the heat exchanger disposed in the circuit, it can be discharged from the outdoor outlet provided on the back of the main body by the same cross fan 70.

That is, for a single cross fan that rotates in only one direction, the tongue that controls the direction of flow is located in the indoor ventilation circuit away from the heat exchanger and closer to the indoor air outlet. By arranging the ventilator at a position close to the heat exchanger in the outdoor ventilation circuit, the outdoor blowing direction and the indoor blowing direction can be set to be opposite directions.

Furthermore, by making the upper part of a single heat exchanger act as an evaporator and the lower part acting as a condenser, drain water condensed in the upper part of the heat exchanger can be removed in the direction of gravity, that is, without the need for a splasher driven by a drain motor. Can be done. As for the heat exchanger, it goes without saying that even if it is divided into two parts and arranged one above the other, the same effect can be obtained.

EXAMPLE Hereinafter, an integrated air conditioner according to an example of the present invention will be described with reference to the drawings.

FIG. 4 shows a side sectional view of an integrated air conditioner according to an embodiment of the present invention.

The operation of the integrated air conditioner configured as described above will be described below with reference to FIGS. 1, 2, 3, and 4.

Indoor air sucked in from the indoor intake port 16 provided on the side of the main body 11 is passed through the heat exchanger 1 which functions as an evaporator.
After passing through the upper part of the main body 11, the cross flow fan 14 supplies cool air into the room from an indoor outlet provided on the front surface of the main body 11 as shown by arrow A in FIG.

On the other hand, the outdoor air taken in from the outdoor intake port 23 on the back side of the main body 11 is directed outdoors to the outside rather than functioning as a condenser.
It is discharged as shown by arrow B in the figure.

That is, for a single cross 70-fan 14 that rotates in only one direction (e.g. clockwise), the tongues that control the direction of flow are moved away from the heat exchanger 15 in the indoor ventilation circuit. By disposing the tongue part 21 at a position close to the indoor air outlet 17 and disposing the stabilizer 25 at a position close to the heat exchanger 15 in the outdoor ventilation circuit, the direction of the outdoor air outlet can be adjusted. (inlet direction in FIG. 2) and indoor blowing direction (direction B in FIG. 3) can be set in opposite directions (for example, at an angle of about 180°).

Furthermore, by arranging the heat exchanger 15 in a substantially vertical direction, and locating the upper part in the indoor ventilation circuit and the lower part in the outdoor ventilation circuit, the upper part of the heat exchanger 15 can be used as an evaporator. The drain water condensed on the surface of the fins can be dripped into the lower part of the heat exchanger 15 which functions as a condenser.

That is, the drain water dripped into the lower part of the heat exchanger 15 acts to increase the condensing capacity, gains heat, evaporates, and is discharged outdoors together with the outdoor air blown as shown by arrow B in FIG. 3. Can be done.

Effects of the Invention As described above, the present invention provides a means for connecting the indoor ventilation circuit and the outdoor ventilation circuit by penetrating in the axial direction a through hole provided in a partition plate that partitions the indoor ventilation circuit and the outdoor ventilation circuit. By arranging a single cross 70-fan so as to be rotatable across the space, the functions of an indoor side blower and an outdoor side blower can be performed by the single cross 70-fan, which reduces material costs. can. Furthermore, the heat exchanger is arranged almost vertically,
