Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an integrated air conditioner, and in particular, the invention is made by improving the structure of a wind guide plate surrounding a propeller fan with a slinger ring.

"Prior Art" In a conventional integrated air conditioner, a propeller fan 22 with a slinger ring is attached to an outdoor heat exchanger 21.
are arranged facing each other, and a baffle plate 23 is provided surrounding them, and a separately formed bell mouth 24 is fixed to the suction port of this baffle plate 23 with a plurality of screws.

"Problems to be Solved by the Invention" However, according to the above conventional structure, the bell mouth 24 is fixed to the air guide plate 23 with a plurality of screws, which makes the installation extremely troublesome and the assembly difficult. It has the disadvantage that it requires a lot of man-hours, and since the bell mouth 24 does not have a water drain, some of the condensed water rises along the bell mouth 24 due to wind pressure when the propeller fan 22 with a slinger ring rotates. , it has the disadvantage that it falls from the top and hits the propeller fan 22, generating noise.

"Means for Solving the Problems" The present invention eliminates the above-mentioned conventional drawbacks, and provides an air conditioner in which a propeller fan with a slinger ring is disposed opposite to an outdoor heat exchanger. A projecting edge is formed at the suction port of the air guide plate surrounding the fan, and a plurality of slits are formed in the fitting part of a separately formed bell mouth that is attached to the projecting edge, and a part of the slits also serves as a water drain. It is formed by forming a long slit.

``Example'' The present invention will be explained with reference to an example shown in the figure below. 1 is a main body base of an integrated air conditioner, and on the main body base 1 there is a partition plate 2 that partitions an indoor side and an outdoor side. An indoor heat exchanger 3 and a Shirotsuko fan 4 are arranged on the indoor side, and an outdoor heat exchanger 5, a propeller fan 6 with a slinger ring, a baffle plate 7 surrounding these, and the Shirotsuko fan on the outdoor side. 4, a fan motor 8 for driving the propeller fan 6, a compressor 9, and the like are provided. A projecting edge 10 is formed at the suction port of the baffle plate 7, and a bell mouth 11 made of synthetic resin is attached to the projecting edge 10. This bell mouth 11 is formed with a cylindrical fitting part 12 having a recess for fitting into the protruding edge 10, and a plurality of slits 13 are formed in the fitting part 12 in the mounting direction. A slit 14, which is slightly longer than the other slits, is formed in a part of the slit 13 so as to communicate with at least the front and back of the fitting portion of the protruding edge 10, which also serves as a drain.

"Function" In the above-described configuration, when attaching the bell mouth 11 to the suction port of the baffle plate 7, the fitting part 12 is aligned with the protruding edge 10 of the baffle plate 7, and the fitting part 12 is pressed against the slit 13. As a result, the tip of the fitting portion shrinks so that the protruding edge 10 can be easily fitted into the recess, and the elastic recovery of the material prevents its return and fixes it in a predetermined position. Furthermore, by locating the slit 14 of the bell mouth 11 at the lower part, the slit 14 is formed to have a length extending from the front to the rear of the fitting portion of the protruding edge 10, so that the required portion beyond the protruding edge 10 can be A water drain portion 15 can be formed,
The water that is about to rise along Bellmouth 11,
The water can be quickly removed through the water draining section 15.

"Effect of the invention" As described above, in the present invention, when attaching the bell mouth to the air guide plate, the fitting part of the bell mouth is pressed against the protruding edge and fitted, which is a simple operation. Therefore, the assembly can be greatly simplified and the number of assembly steps can be greatly reduced compared to conventional bell mouths that are fixed with screws. In addition, a part of the slit formed in the fitting part of the bell mouth is made longer to form a water drainage part between it and the protruding edge. The water that tries to rise along the line is removed through the drain section, and unlike conventional models, it does not hit the propeller fan and generate noise, making it possible to provide an extremely quiet air conditioner. can.
