DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With the above structure, a turbulent flow of intake air is prevented from occurring near an outer peripheral edge of a rib erected on a casing having a connecting portion for connecting a plurality of cross flow fans, thereby reducing noise. This is an air conditioner that prevents generation and prevents static pressure characteristics from lowering.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1A to 1C and FIG. 2A
2 (B), reference numeral 1 denotes an indoor unit main body of the air conditioner, 2 denotes a suction port provided on the front and top surfaces of the main body 1, and 3 denotes a blowout constituted by the suction port 2 and a casing described later. The heat exchanger is provided in an air passage connecting to an outlet, and has a dew receiving portion below.

Reference numerals 4a and 4b denote a plurality of cross flow fans for sending suction air sucked in from the suction port 2 and heat exchanged by the heat exchanger 3 toward an air outlet described later. 4a and 4b are provided in the air passage through a stabilizer 8 continuous with the dew receiving portion, and are coaxially connected by a semicircular connecting portion (described later) of a pair of ribs erected on a casing (described later). It is the configuration that was done. 4c is the cross flow fan connected
This is a drive motor for driving 4a and 4b.

Reference numeral 5 denotes a casing which constitutes the main body 1 and is disposed in an air passage.
The heat is exchanged in, forming an outlet 5a for blowing out the air sent out by the cross flow fans 4a and 4b,
A pair of ribs 5b having a semicircular connecting portion a for connecting the cross flow fans 4a and 4b is provided upright.

Reference numeral 6 denotes a group of left and right wind direction plates which are rotatably supported by the outlet 5a and adjusts the direction of air flow in the left and right direction. Reference numeral 7 denotes an intermediate shaft portion b in front of the group of right and left wind direction plates 6. And at least one vertical wind direction plate that is rotatably supported and adjusts the vertical wind direction.

The stabilizer 8 and the outer peripheral edge a 'of the rib 5b having the connecting portion a are connected by a connecting rib 9 near the outer peripheral edge a' for preventing a suction air from being turbulent. And the ribs
The structure prevents noise from being generated in the vicinity of the outer peripheral edge a 'of 5b, and also prevents static pressure characteristics from being lowered.

Further, since a plurality of the connecting ribs 9 are provided between the stabilizer 8 and both sides of the outer peripheral edge a 'of the rib 5b, the connecting rib 9 is sucked from the suction port 2 and the heat exchanger 3 is provided.
The configuration is such that the suctioned air that has been heat-exchanged in the above can be more effectively prevented from being caught in the vicinity of the outer peripheral edge a ′ of the rib 5b.

Further, by connecting the lower end of the connecting rib 9 to the bottom surface of the casing 5, the suction air sucked from the suction port 2 and exchanged with the heat exchanger 3 is removed from the outside of the rib 5b. The structure is such that it can be more effectively prevented from being caught in the vicinity of the peripheral edge a '.

Further, since the connecting rib 9 is formed integrally with the casing 5, the dimension and shape can be finished with high accuracy, and the cost is advantageously reduced.

With the above configuration, FIGS.
(C), and as shown in FIGS. 2 (A) and 2 (B), by connecting the stabilizer 8 and the outer peripheral edge a ′ of the rib 5b by the connection rib 9, the suction port 2
The suction air which has been sucked in from the heat exchanger 3 and has heat exchanged therewith is provided with a connecting portion a for connecting the plurality of cross flow fans 4a and 4b. An air conditioner that is prevented from being caught in the vicinity so as to prevent generation of noise and prevent static pressure characteristics from lowering.
