Reference numeral 1 denotes a main body, on which a partition plate 4 is provided on a base 2, thereby mounting unit units partitioned and formed on the indoor side and the outdoor side. Reference numeral 5 denotes a motor mount for holding a blower motor 6, which is fixed to the base 2. Reference numeral 2a denotes an indoor heat exchanger, which is disposed on the indoor front surface of the main body 1. 7 is the indoor heat exchanger 2a
The suction port 73 is connected to a blowout port (not shown) by a fan casing provided on the back surface of the fan, and forms an air passage together with the partition plate 4. Reference numeral 8 denotes a sirocco fan which is installed in the fan casing 7 and sends cold air into the room via the suction port 73, the air path and the air outlet.

Not only that, the water is also scattered on both sides and the upper surface of the air guide plate 33 forming the air path. In particular, the drain water scattered on the ceiling (upper surface) of the air guide plate 33 grows little by little to form large water droplets. It falls to 9 and finally falls on the rotating propeller fan 31, for example, at point A. At this time, the sound of khan and khan was emitted, and if this continued, the noise was surprisingly loud and caused the complaint.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an integrated air conditioner according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an embodiment of an integrated type air conditioner according to the present invention. FIG. 1 is a longitudinal sectional view (a) of an essential part, a view AA ′ (b), and a transverse view BB ′. ) And CC ′ horizontal sectional view (d). The fan casing 7 provided on the back surface of the indoor heat exchanger 2a is provided with a sirocco fan 8 as shown in FIG. Are connected. A branch 74 is provided in an air path (blow-out portion) connected to the air outlet 72 to newly branch the second air path 71, and the tip of the second air path 71 shown in FIG. It was installed so as to open along the air guide plate 33.

The rotation of the sirocco fan 8 causes the front panel 20 to pass through a plurality of through holes for air circulation for suction,
The air (cooling air) taken into the fan casing 7 via the indoor heat exchanger 2a and further via the suction port 73 is blown into the room from the outlet 72 through the outlet hole of the front panel 20. I do. On the other hand, a part of the taken-in air is diverted from the branch port 74 provided in the blow-out portion via the second air passage 71, and is led to the second air passage 71, from the opening at the tip to the vicinity of the ceiling. It blows toward the air guide plate 33.

As shown in FIG. 3, conventionally, the drain water scattered on the ceiling (upper surface) of the baffle plate 33 grows little by little to become large water droplets 9 and finally the propeller fan 3 which is rotating finally.
For example, the noise generated by dropping on point A, for example, at point A has been a problem, but the cool air blown from the second air passage 71 toward the wind guide plate 33 causes the ceiling ( The drain water scattered to the upper surface (upper surface) is blown forward and moves, reaches the upper portion of the outdoor heat exchanger 32, and sequentially wets and flows down the outdoor heat exchanger 32. Therefore, large water drops 9 are not generated, and the above-mentioned noise problem can be solved.

Further, as shown in FIG. 1B, the tip of the second air passage 71 is installed in parallel with the baffle plate 33 and the opening of the tip is formed to have the same width as the baffle plate 33. With the rectangular shape, the water droplets adhering to the ceiling of the baffle plate 33 can be blown off toward the outdoor heat exchanger 32 by the strong wind blown out from the gap between the nozzle-shaped narrow tip openings.

Further, as shown in FIG. 1A, the front opening of the second air passage 71 in the preceding section is bent upward at a required angle in the direction of the baffle plate 33 so that the air can be blown from the gap of the front opening. The strong wind to be blown can be optimally and efficiently applied to the ceiling of the wind guide plate 33.

Further, as shown in FIG. 1 (d), the second air passage 71 of the previous section is provided with a wind direction adjusting means constituted by a partition member 75 therein. In this example, the wind flowing into the second air passage 71 by the partition member 75 changes its direction to the left, and can be blown out from the left, right, and center portions of the tip opening on average. Almost all water droplets adhering to the ceiling of 33 can be blown off toward the outdoor heat exchanger 32.

[0017]

As described above, the integrated air conditioner of the present invention is capable of preventing large water droplets from falling onto the propeller fan by blowing off the water droplets by the strong wind blowing from the nozzle-shaped narrow tip opening. It is to prevent. Therefore, the noise generated when a large water droplet collides with the propeller fan can be reduced, and the noise of the integrated air conditioner can be reduced.
