It is an object of the present invention to provide an integrated air conditioner that has been described above.

[0006]

According to the present invention, in order to solve the above-mentioned problems, the inside of a main body is divided into an indoor side and an outdoor side by a partition plate erected on a base. And a centrifugal fan opposed thereto, which drives a compressor, an outdoor heat exchanger, a propeller fan with a circular slinger ring facing the compressor, the propeller fan and the centrifugal fan. And a wind guide plate provided with a substantially cylindrical bell mouth surrounding the outdoor heat exchanger and the propeller fan, and drain water derived from the indoor heat exchanger was provided on an outdoor base. In the integrated air conditioner, the drainage water in the water receiver is scattered to the outdoor heat exchanger and is evaporated by guiding the water to the water receiver and rotating the slinger ring. sex It has a configuration in which deposited water retention member having.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as examples. FIG. 1 is a cross-sectional view of an integrated air conditioner according to the present invention (and a conventional example), FIG. 2 is a perspective view of a main part of the integrated air conditioner according to the present invention (and a conventional example), and FIG. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view of a main part of an integrated air conditioner according to the present invention, wherein (A) is a front view showing a first embodiment, (B) is a side view showing a first embodiment, and (C) is a second embodiment. FIG. 14 is a perspective view showing an example, (D) is a cross-sectional view showing a third embodiment, and (E) is a cross-sectional view showing a fourth embodiment.

In the integrated air conditioner according to the present invention, as shown in FIG. 1, the inside of the main body has a partition plate 2 erected on a base 1.
The partition is divided into an outdoor side A and an indoor side B.

An air passage connecting an inlet a provided on one front side of the indoor side B and an outlet b provided on the other side has an indoor heat exchanger 8 and a centrifugal opposing the heat exchanger. Fan 14
Are provided.

On the outdoor side A, a compressor 3, an outdoor side heat exchanger 4, and a circular slinger ring 10 facing the compressor 3 and the outdoor side heat exchanger 4.
A propeller fan 7, a motor 6 for driving the propeller fan 7 and the centrifugal fan 14, a wind guide plate 5 having a substantially cylindrical bell mouth surrounding the outdoor heat exchanger 4 and the propeller fan 7, Is provided.

Propeller fan 7 with slinger ring 10
The indoor heat exchanger 8
A water receiving portion 9 for receiving drain water derived from the base 1 is provided, and an outer shell 15 is attached to the base 1.

As shown in FIGS. 4A and 4B, the slinger ring 10 is usually constituted by a thin plate-shaped ring attached to the outer periphery of the propeller fan 7. However, with this configuration, as described in the above-described related art, a large amount of the drain water accumulated in the water receiving portion 9 cannot be removed.

Therefore, in the present invention, as shown in FIGS. 3A and 3B as a first embodiment, the water retaining member 11 having a water absorbing property is provided on the outer peripheral surface of the slinger ring 10.
Is attached.

As described above, since the water retaining member 11 is attached to the outer peripheral surface of the slinger ring 10, the water retaining member 11 can be continuously scraped while a large amount of drain water is absorbed. As a result, the amount of water sprayed over the entire area of the outdoor heat exchanger 4 by the wind pressure of the propeller fan 7 can be increased.

Since a large amount of drain water can be evenly distributed over the entire area of the outdoor heat exchanger 4, the outdoor heat exchanger 4 can be cooled effectively, and the heat exchange efficiency can be effectively improved. Can be improved.

As shown in FIG. 3C as a second embodiment, a large number of projecting pieces 12 are integrally formed on the outer periphery of the water retaining member 11, or as a third embodiment, as shown in FIG. As shown in FIG. 3), the water retaining member 11 is formed in an L-shaped cross section, or as a fourth embodiment, as shown in FIG. May be formed in an annular shape.

Thus, the contact area between the water retaining member 11 and the drain water accumulated in the water receiving portion 9 is increased so that water can be efficiently absorbed, or the plurality of projecting pieces 12 can be efficiently absorbed.
A large amount of water can be effectively pumped between the comrades and in a state where the L-shaped section and the groove 13 are also entrapped or kept in water.

[0022]

As described above, according to the present invention,
The integrated air conditioner has a structure in which the slinger provided on the propeller fan can be sprinkled uniformly over the entire area of the outdoor heat exchanger by sweeping a large amount of water.
