Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated air conditioner.

[0002]

2. Description of the Related Art The structure of a conventional integrated air conditioner will be described with reference to FIGS. 1, 4 and 5.

FIG. 1 is an exploded perspective view of an integrated air conditioner according to the present invention. Since only the protrusion direction of the groove of the top plate is different from that of the conventional example, description will be given with reference to FIG. In FIG.
The main body 1 of the integrated air conditioner has a partition wall 5 for partitioning a substrate 2 and an indoor ventilation path 3 and an outdoor ventilation path 4 on the substrate 2.
And an outer box 6. An outdoor heat exchanger 7 is attached to the rear surface of the outdoor ventilation path 4, and a fan motor 8 is attached to the partition wall 5 so that the rotation axis is vertical. A propeller fan 9 integrated with a slinger ring that blows air toward the outdoor heat exchanger 7 is attached to one end of the fan motor 8. Reference numeral 10 is a compressor that constitutes a well-known refrigeration cycle together with the outdoor heat exchanger 7.

In the indoor ventilation path 3, a water tray (not shown) and a wind tunnel 11 are mounted on the substrate 2, and the indoor heat exchanger 13 is placed on the water tray so as to face the front grill 12. Is attached. A multi-blade fan (not shown) attached to the other end of the fan motor 8 guides wind from the intake port 14 of the front grill 12 to the wind tunnel 11.
The air is blown to the air outlet 15. The outer box 6 is formed in a tubular shape by the back surface, the left side surface, the right side surface, the top surface, and the bottom surface of the main body 1, and has a top surface suction louver 16 and a side surface suction louver 17 on the top surface and the left and right side surfaces, respectively. . The back surface of the outer box 6 has an outlet (not shown) to which a guard net (not shown) is attached. In addition, 18 is a capillary tube which comprises a refrigerating cycle. Reference numeral 19 is a top plate that covers the indoor side ventilation path 3 and the outdoor side ventilation path 4, and the top plate of the conventional example is shown in FIGS.
As shown in FIG. 3, a groove 19d is formed so as to project upward and substantially follow the direction in which the condensed water scatters, and is inclined with respect to the rotation direction of the propeller fan 9 in which slinger rings are integrated.

[0005]

However, in the above configuration, when the condensed water accumulated in the water receiving tray is blown to the outdoor heat exchanger 7 by rotating the propeller fan 9 having the slinger ring integrated therein, Since some of the condensed water sprayed on the plate 19 flows in the rotation direction of the propeller fan 9, there is a problem that the original function of cooling the outdoor heat exchanger 7 is not sufficiently satisfied.

The present invention solves the above-mentioned problems of the prior art. When the condensed water accumulated in the water receiving tray is blown to the outdoor heat exchanger, some of the condensed water blown to the top plate rotates the propeller fan. The purpose of this is to prevent the flow of heat in the direction and to sufficiently fulfill the function of cooling the original outdoor heat exchanger.

[0007]

In order to achieve the above-mentioned object, the present invention is one in which a groove projecting downward is formed in a top plate which covers the upper portions of the indoor side ventilation path and the outdoor side ventilation path.

In addition, a groove that is inclined with respect to the rotating surface of the propeller fan integrated with slinger rings so as to be substantially along the direction of condensate dispersion and is gradually displaced toward the outdoor heat exchanger is used as the top plate. It was formed.

Further, all the grooves which are inclined with respect to the rotating surface of the propeller fan integrated with the slinger ring so as to be substantially along the scattering direction of the condensed water and which are gradually displaced toward the outdoor heat exchanger are the outdoor heat. It is placed on the top plate so that it is located above the exchanger.

[0010]

In the above structure, according to the present invention, when the condensed water accumulated in the water receiving tray is blown to the outdoor heat exchanger by rotating the propeller fan integrated with the slinger ring, the condensed water attached to the ceiling plate is Since the groove protruding below the plate is provided, condensed water is more likely to adhere to the groove than the groove protruding upward, and it is easier for the condensed water to propagate through the groove, preventing the propeller fan from flowing in the rotation direction, and reducing the original outdoor heat. The function of cooling the exchanger will be more effectively satisfied.

When the condensed water accumulated in the water receiving tray is blown to the outdoor heat exchanger by rotating the propeller fan integrated with the slinger ring, the condensed water adhering to the top plate is condensed water on the top plate. The wind generated from the propeller fan is inclined to the rotation surface of the propeller fan with integrated slinger ring so as to be almost along the scattering direction, and the groove is gradually shifted toward the outdoor heat exchanger. Since it can be more smoothly propagated through the groove by using, the flow of the propeller fan in the rotation direction can be prevented and the original function of cooling the outdoor heat exchanger can be more effectively satisfied.

Further, when the condensed water accumulated in the water receiving tray is blown to the outdoor heat exchanger by rotating the propeller fan integrated with the slinger ring, the condensed water attached to the top plate is condensed water on the top plate. The propeller that has slinger rings integrated so as to almost follow the scattering direction is inclined with respect to the rotation surface of the propeller fan, and all the grooves that are gradually displaced toward the outdoor heat exchanger come to the upper part of the outdoor heat exchanger. The wind force generated by the fan is used to travel through the groove more reliably and directly, preventing the propeller fan from flowing in the direction of rotation and effectively cooling the original outdoor heat exchanger. Will be met.
