DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIGS. 1 and 2, reference numeral 1 is an indoor unit, which is provided with an indoor fan 2, an indoor heat exchanger 3, an indoor water tray 4, a humidifier 5 and an indoor intake / exhaust port 6. 7
Is an outdoor unit and includes a compressor 8, an outdoor heat exchanger 9, an outdoor fan 10, and an outdoor water tray 11. Then, through the through hole formed in the wall 12 of the house, the connection unit 13
Thus, the indoor unit 1 and the outdoor unit 7 are connected. The connection unit 13 includes the refrigerant pipe 14 and the energizing wire 1
5 and the condensed water flow pipe 16 and the air flow pipe 17.

Therefore, the connection unit 13, that is, the refrigerant passage pipe 14, the conducting wire 15, the condensed water passage pipe 16, the air passage pipe 17
Each of them has a size close to the through hole formed in the wall 12, and the length is generally fixed to about the thickness of the wall so that it is not unnecessarily lengthened. Since the connecting portion between the indoor unit 1 and the outdoor unit 7 is almost invisible from the outside, the external appearance may be better than that of the conventional example shown in FIG. Further, since the length of the connection unit 13 is short, the refrigeration cycle efficiency for the refrigerant is good, and when the length of the refrigerant passage (pipe) is too long as in the conventional example, or when the outdoor unit is installed at the installation position of the indoor unit. There is no failure that occurs when it is placed at a very high position compared to. Moreover, since the connection unit 13 can be installed in advance in either the indoor unit 1 or the outdoor unit 7, the connection unit 13 is not connected in advance during the installation work of the air conditioner. , 7, it is only necessary to connect to one of the two, so that the work of connection work at the site can be saved, and in addition, there are few failures due to refrigerant leakage due to a failure of the connection work. In particular, the outdoor unit 7 and the refrigerant passage 14
By using a one-shot, that is, a connecting device capable of self-sealing the joint portion 18, the connection work can be further simplified and ensured.

Regarding energization, the number and length of electric wires and the drive motors of the compressor 8, the indoor fan 2, or the outdoor fan 10 are fixed, and the electronic control for controlling the outdoor unit 7 is performed. Since the device can be mounted on the indoor unit 1, the reliability of the electronic control device can be improved and the electronic control device can be easily repaired.

Regarding the condensed water passage pipe 16, the condensed water obtained in the indoor unit 1 during cooling is passed to the outdoor unit 7 through the condensed water passage pipe 16, or the condensed water obtained in the outdoor unit 7 during heating. Water can be easily passed through the condensed water passage 16 to the indoor unit 1.

Regarding air, the air can be easily and stably circulated between the indoor unit 1 and the outdoor unit 7 through the air circulation pipe 17.

The outdoor unit 7 has a wall 12 on its rear surface.
It is composed of an installation plate 19 that can be directly installed in, an outdoor water tray 11 is provided at the center, and an outdoor heat exchanger 9 and an air circuit unit 20 having an outdoor fan 10 are provided above it. A refrigeration cycle unit 21 having a compressor 8 is formed below the outdoor water tray 11. Therefore, the outdoor unit 7 mounts its mounting plate 19 directly on the wall 12 by fixing screws 22.
The outdoor unit 7 can be fixed on the wall 1 because it can be fixed with a fixture such as
It can be attached closely to 2 without any gaps.

Further, since the outdoor water receiving tray 11 is formed in the central portion of the outdoor unit 7, the wind circuit portion 20 is formed in the upper portion thereof, and the refrigeration cycle portion 21 is formed in the lower portion thereof, the outdoor unit 7 is formed.
When the height of the outdoor water tray 11 is matched with the height of the indoor water tray 4 of the indoor unit 1, the installation height of the outdoor unit 7 can be set without being considerably higher than the installation height of the indoor unit 1. . Therefore, it is possible to lower the outdoor unit water receiving tray of the outdoor unit 7 compared to the case where the roof of the outdoor unit hits the roof of the house. Since the top surface, the front surface, and both side surfaces of the upwind circuit portion 20 can be used as ventilation openings, ventilation is possible as shown by the white arrow in the figure, and ventilation efficiency is good. Further, since the compressor 8 which is heavier than other parts is installed in the lower portion of the outdoor unit 7, the outdoor unit 7 is attached to the wall 1.
2 can be installed stably.

The indoor water receiving tray 4 for temporarily storing the condensed water generated in the indoor heat exchanger 3 and the outdoor water receiving tray 11 for temporarily storing the condensed water generated in the outdoor heat exchanger 9 have the same height. Both of them are connected by the condensed water passage pipe 16 and are in a water-permeable state.

Therefore, the condensed water generated in the outdoor heat exchanger 9 during heating is temporarily stored in the outdoor water receiving tray 11,
The water is also stored in the indoor water tray 4 through the condensed water passage 16.

By providing the vaporizing type humidifier 5 at the intake port of the indoor unit 1, the humidifier 5 sucks up the condensed water stored in the indoor water tray 4 and vaporizes it. It will be possible. In this case, since the human power (water supply to the tank, etc.) and the pump etc. necessary for supplying water to the indoor water tray 4 are not required, the structure is simple,
Not only does it save labor and electricity, but it also eliminates the troubles such as clogging of the pump due to water stains and dust that often occur when using the pump. On the other hand, even during cooling, the condensed water generated in the indoor heat exchanger 3 and stored in the indoor water tray 4 can be stored in the outdoor water tray 11 through the condensed water passage 16, so that the surroundings of the outdoor fan 10 can be reduced. By providing the blades on the outside, the condensed water in the outdoor water tray 11 can be scraped up to the outdoor heat exchanger 9 to be cooled and the refrigeration cycle efficiency during cooling can be improved.

An indoor air intake / exhaust port 6 is provided in the air intake part of the indoor unit 1 (in FIG. 1, the ventilation direction of the indoor unit 1 is shown by a white arrow), and an outdoor air intake / exhaust port is provided in the air intake part of the other outdoor unit 7. 23 respectively, and the indoor intake and exhaust ports 6
And the outdoor intake / exhaust port 23 are connected to each other by an air flow pipe 17 so that mutual ventilation is possible.

Therefore, when the rotation of the outdoor fan 10 of the outdoor unit 7 is stopped while the indoor fan 2 of the indoor unit 1 is rotated, the static pressure of the indoor intake / exhaust port 6 is changed to the outdoor intake / exhaust port 23. Since the static pressure becomes lower than the static pressure, the outdoor air flows into the room through the air circulation pipe 17.
On the other hand, when the outdoor fan 10 of the outdoor unit 7 is rotated more strongly than the indoor fan 2 of the indoor unit 1, the static pressure of the indoor intake / exhaust port 6 is higher than the static pressure of the outdoor intake / exhaust port 23. Therefore, the air in the room flows out through the air flow pipe 17. In the case of cooling operation,
The cool air flowing out of the room has a high cooling efficiency because it cools the outdoor heat exchanger 9 of the outdoor unit 7, and the warm air flowing out of the room during the heating operation is the outdoor heat exchange of the outdoor unit 7. Since the container 9 is heated, a part of the heat in the air is recovered as the heat for heating the room.

[0034]

As is apparent from the above embodiments, the present invention improves the appearance because the connecting unit for connecting the indoor unit and the outdoor unit is short and its length is fixed.
Not only can efficiency and reliability on the refrigeration cycle be improved and serviceability be improved, but humidification and ventilation during heating can be realized with a simple configuration.

The rear surface of the outdoor unit is a mounting plate,
When the outdoor water tray is provided in the center, and the upper part is the wind circuit part and the lower part is the refrigeration cycle part, the structure is simple and close to the wall, and the relative position with the indoor unit does not greatly shift. Therefore, it is possible to perform the installation with extremely stable weight, without impairing the degree of freedom of the installation location. Since the top, front and both sides of the upper outdoor unit can be used as ventilation areas, an efficient wind circuit can be obtained.

Further, when the indoor and outdoor water pans are constructed so as to have the same height, and both are connected by the condensed water passage pipe of the connection unit, they are generated in the outdoor unit during heating. Condensed water is naturally stored in the indoor water tray,
Since vaporized humidification can be performed using the water, highly reliable humidification that does not require maintenance and electricity charges can be realized with a simple configuration. On the other hand, at the time of cooling, the condensed water generated in the indoor unit is naturally stored in the outdoor water tray and is utilized for cooling the outdoor heat exchanger, so that efficient cooling operation can be realized.

Further, when the air intake portion of the outdoor unit and the air inlet portion of the indoor unit are connected by the air circulation pipe of the connection unit, the indoor fan and the outdoor fan are simply controlled to control the indoor speed. Since it is possible to intake and exhaust, it is possible to realize highly efficient ventilation in the room with a simple configuration.
