SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the inside of the main body is divided into an indoor unit side and an outdoor unit side by a partition plate, and the indoor unit side is provided with indoor heat. An indoor heat exchanger room for arranging the exchanger and the indoor blower, an air passage for the heat-exchanged air, and an operating section are provided, and the outdoor fan and the outdoor heat exchanger are arranged on the outdoor unit side, and both In an air conditioner in which an air guide plate having an outlet for an outdoor blower is erected between the partition plate and the air guide plate, the air on the outdoor heat exchanger side is supplied to the indoor heat exchanger chamber. An intake pipe to be introduced into the exhaust pipe, an exhaust pipe that guides a part of the air blown out from the indoor blower to the outdoor blower side is provided between the upper portions of the other sides, and a first damper is provided on the outlet side of the intake pipe. 2nd dampers are installed on the inlet side of the Was Unishi.

[0005]

With the above configuration, the air (outside air) passing through the intake pipe on the intake side is pushed by the wind pressure of the propeller fan of the outdoor blower and is pulled by the intake force of the indoor blower, so that the amount of air in the room is reduced. On the exhaust side, the air passing through the exhaust pipe is pushed by the wind pressure of the indoor blower and is pulled by the intake force of the propeller fan of the outdoor blower, which increases the amount of air to the outside, improving ventilation capacity. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Fig. 1 shows the appearance of a wind type air conditioner, and Fig. 2 shows the internal structure of the air conditioner.
Reference numeral 1 is a main body (box), 2 is a front panel, and 3 is an operation unit. There is an outside air intake port 1a on one side of the main body 1, and a front panel 2 is provided with an indoor air intake port (suction grille) 2a and an outlet port 2b. As shown in FIG. 2, the inside of the main body 1 is divided into a front indoor unit side A and a rear outdoor unit side B by a partition plate 5 provided upright on a base 4, and the indoor unit A has an indoor heat exchanger. There is a room 6 and an indoor heat exchanger 7,
An indoor blower (sirocco fan) 8, a part of which is indicated by a broken line, is arranged, and the heat-exchanged air passes through the ventilation passage 9 on the front right side of the partition plate 5 and is discharged into the room from the air outlet 2b shown in FIG. It has become so. Further, an outdoor blower (propeller fan) 10 and an outdoor heat exchanger 11 are arranged on the outdoor unit side B behind the partition plate 5, and between the outdoor blower 10 and the outdoor heat exchanger 11, the outdoor blower 10 is provided. A baffle plate 13 having a blow-out port 12 for is installed upright. The air for cooling the outdoor heat exchanger 11 is introduced from the suction port 1a formed on the side surface of the main body 1 into the ventilation passage 14 formed by the partition plate 5, the air guide plate 13 and the like, and the outdoor blower 10 exchanges the outdoor heat. The air is blown to the device 11 and is exhausted from the rear surface of the outdoor heat exchanger 11.

By the way, the feature of this air conditioner is that the intake pipe for introducing the air of the outdoor heat exchanger 11 side into the indoor heat exchanger chamber 6 at the upper part of one side between the partition plate 5 and the baffle plate 13. 15 is provided, an exhaust pipe 16 for guiding a part of the air blown from the indoor blower 8 to the ventilation passage 14 in which the outdoor blower 10 is arranged is provided between the upper portions of the other sides, and the first side is provided on the outlet side of the intake pipe 15. And a second damper 18 on the inlet side of the exhaust pipe 16, and these dampers 17 and 18 and the operating lever 1 of the operating portion 3
As shown in FIG. 3, 9 and 20 are connected by cable conduits 21 and 22, respectively, and the dampers 17 and 18 can be arbitrarily opened and closed. The intake pipe 15 has a cylindrical shape with both sides opened, but the exhaust pipe 16 has an outlet 23 at the rear of the exhaust pipe 16 for guiding the air on the indoor unit side A to the ventilation passage 14 on the outdoor unit side B. It is provided on the periphery. In the ventilation operation in which the air on the outdoor unit side B is circulated in the room, the indoor blower 8 and the outdoor blower 10 are operated at the same time.

[0008]

According to the air conditioner as described above, during ventilation operation, the air passing through the intake pipe is pushed by the wind pressure of the propeller fan of the outdoor blower and pulled by the intake force of the indoor blower. Therefore, the amount of air in the room increases, while the air passing through the exhaust pipe is pushed by the wind pressure of the indoor blower and pulled by the intake force of the outdoor blower, which increases the amount of air to the outside In addition to improving the capacity, the intake pipe and the exhaust pipe also serve as a reinforcing member between the partition plate and the air guide plate, so that a dedicated reinforcing member that has been conventionally used is not required and the cost can be reduced.
