Description

[Detailed Description of the Invention] The present invention relates to a mouth ring structure for an air conditioner. The mouth ring structure of a conventional air conditioner will be explained with reference to FIGS. 1 and 2. The arrows in FIG. 1 indicate the flow of indoor air. 1 is a compressor,
2 is an evaporator, and 3 is a condenser, forming a part of the refrigeration cycle. 4 is a fan motor, 5 is an indoor fan, and 6 is a propeller fan, and these members form an air blower. Further, a mouth ring 7 is disposed between the evaporator 2 and the indoor fan 5, and a vent hole 7a is opened in the mouth ring 7 at a position facing the indoor fan.
A dew pan 8 is provided at the bottom of the evaporator 2.
9 covers the indoor fan 5 with a casing. They are partitioned into an indoor side and an outdoor side by a partition plate 10, and are mounted on a base 11 and housed in an outer box 12. 18 is a decorative cover, which has an air inlet and an air outlet, and is connected to the base 1.
Opening 12a for inserting and attaching 1 into outer box 12
It covers the In this structure, when the air conditioner is operated for cooling under high humidity conditions, the indoor air flows as shown by the arrow in FIG. may condense on the surfaces of the low-temperature casing 9 and the mouth ring 7, causing condensation on both sides of the mouth ring 7, the surface on the evaporator 2 side and the surface on the indoor fan 5 side. Further, among the dew on both sides of the mouth ring 7, the dew on the surface facing the indoor fan 5 may flow out and drip into the inside of the casing 9 and further into the base 11. In this case, the water that dripped and accumulated on the casing 9 is
In some cases, it was scraped out by the indoor fan 5 and scattered indoors. In addition, the dew dropped on the base 11 is
The base 1 on the decorative cover 18 side is passed through the slight gap between the casing 9 and the dew pan 8 and the base 11.
There was a risk that the liquid would overflow from the upper end of the outer box 12 and drip into the room through the opening 12a for inserting and attaching the base 11 of the outer box 12.

Measures have been taken to prevent the above-mentioned drawbacks, such as pasting a heat insulating material on the mouth ring 7, but the heat insulating material peels off easily and the workability of pasting is poor, so this is not a sufficient measure against mouth ring condensation. . On the other hand, if the mouth ring 7 was to be attached from the front side of the evaporator 2, the shape of the evaporator 2 and the piping would have hindered the work efficiency. The present invention focuses on and improves these drawbacks. That is, the mouth ring 14 is provided with an inclined groove,
Remove the dew that has adhered to both sides of the mouth ring 14 using the dew pan 1.
It has a structure that leads to the inside of 5. An embodiment of the present invention will be described below with reference to FIGS. 3, 4, and 5.

13 is an evaporator, and 14 is a mouth ring of the present invention, which is disposed between a dew pan 15 attached to the lower part of the evaporator 13 and a casing 9 that covers the indoor fan 5. Furthermore, the indoor and outdoor spaces are partitioned by a partition plate 16, which is placed on a base 17. On the other hand, as shown in FIGS. 3 and 4b, the mouth ring 14 has a dew pan 1.
A groove 14a is provided such that the surface on the 5 side is convex and the surface on the indoor fan 5 side is concave. Furthermore, as shown in FIGS. 4a and 4b, the groove 14a has a V-shape with an inclined part 14b formed toward the center so that the dew flowing out can flow smoothly. An opening hole 14c and a weir 14d are provided at the lowest part of the inclined portion 14b to prevent the flowing dew from flowing back toward the casing 9 side. Furthermore, the mouth ring 14 on the evaporator 13 side is provided with fixing wings 14e on both sides. 14f is a ventilation hole for indoor air circulation. Said mouse ring 1
The blades 14e of No. 4 are inserted between the fixed plate 13a formed on both sides of the evaporator 13 and the partition plate 16 from above the partition plate, and are fixed with screws from the side.

According to this structure, even if dew occurs on the surface of the mouth ring 14 on the side of the indoor fan 5, the dew that adheres to the surface and flows out is guided to the groove 14a, and then guided to the opening 14c by the inclined portion 14b. The opening 1
4c, flows into the dew pan 13, and is discharged outside. As a result, the amount of water that accumulates inside the casing 9 and on the base 17 is extremely small, so that it does not overflow from the upper end of the base 17 on the side of the decorative cover, thereby preventing water from dripping into the room. Further, the fixing plates 13a provided on both sides of the evaporator 13 are sufficiently cooled during the specified cooling operation, and if you try to fix them directly to the partition plate 16 on the base 17, the partition plate 16 will also be cooled by heat conduction. In some cases, condensation formed on that surface and flowed out, causing it to fall outside the base. In order to solve this problem, the mouth ring 14 of the above embodiment is made of a non-metal with low thermal conductivity that blocks the heat conduction, and both wings 14e of this mouth ring 14 are connected to the fixing plate of the evaporator 13. It may be inserted between the partition plate 13a and the partition plate 16 and fixed from the side with screws.

As explained above, according to the present invention, the structure is such that the dew on both sides of the mouth ring flows into the dew pan, so that the dew does not drip onto the casing and is removed by the indoor fan and scattered indoors. In addition, the dew that dripped onto the base 1 of the outer box
7. This has the effect of preventing dripping into the room from the insertion opening 12a or the like.
