Description

Drainspout for condensation in ceiling-type air conditioner

The present invention relates to a ceiling type air conditioner, and more particularly, in a case in which a heat exchanger of an indoor unit installed horizontally on an indoor ceiling surface is installed horizontally with respect to a front grill, condensed water generated on the surface of the heat exchanger is The present invention relates to a condensate collecting device which prevents an outflow to the air inlet of the front grill.

In general, a separate air conditioner is a cooling device installed in a space or a wall of a room, such as a shop, an office, or a home, to achieve indoor cooling. The indoor air conditioner includes an indoor unit installed outdoors and an outdoor unit installed outdoors. Is connected to the connecting pipe to enable circulation of the refrigerant.

Among the air conditioners as described above, the indoor unit of the ceiling type air conditioner is to be installed and operated on the ceiling of the room.

The ceiling-type air conditioner is installed in a relatively low-use ceiling in the interior space, and has less advantage of space constraints than a wall-mounted or standing type air conditioner. Another advantage is the growing demand for it.

As shown in FIG. 1, the general configuration of the indoor unit includes a main body 1 supported by a specific support, a cross flow fan 2 axially rotating with a motor 3 installed inside the main body 1, and The heat exchanger 4 converts the air sucked by the cross flow fan 2 into cold air.

The heat exchanger 4 is formed to surround the cross flow fan 2 so that the air sucked by the cross flow fan 2 exchanges with the refrigerant sent from the outdoor unit (not shown).

On the other hand, a front grill 6 having a suction port 5a for sucking indoor air and a discharge port 5b for discharging the heat-exchanged air into the room when the crossflow fan 2 is rotated is installed at the front of the main body 1. .

When the refrigerant compressed and condensed by the outdoor unit is introduced into the heat exchanger 4 of the indoor unit configured as described above, the air forcedly sucked by the cross flow fan 2 is changed into cold air in the heat exchanger 4. The condensation occurs on the outer surface of the heat exchanger 4 due to condensation of water therein.

Thus, along the surface of the heat exchanger 4 at the lower end of the heat exchanger 4 in order to prevent the condensate from falling to the indoor floor through the intake and exhaust ports 5a and 5b formed on the front grill located under the heat exchanger 4. A condensate collector 7 for collecting and discharging the flowing condensate is installed.

On the other hand, in order to increase the heat exchange efficiency while reducing the thickness of the ceiling-type indoor unit configured as described above, the heat exchanger may be installed horizontally, in which case the condensate generated in the heat exchanger is formed at the front of the grill. The problem arises immediately falling to the inlet of.

That is, when the heat exchanger is installed horizontally, there is no need of a "c" shaped bending device for fixing the heat exchanger as in the conventional indoor indoor unit, resulting in convenience of manufacturing and a reduction in manufacturing cost, but a conventional water collecting device. In addition, the shape of the front grill where the condensate drops immediately must be modified.

Therefore, even when the heat exchanger is installed horizontally according to the condition of the installation place of the conventional indoor indoor unit, there is a growing need for a condensate collecting device in which condensate is not discharged to the room without significantly modifying the structure of the conventional indoor unit.

The present invention has been made by the necessity as described above, an object of the present invention is to provide a front grill equipped with a collecting device for collecting and discharging condensate by easily installing the conventional indoor indoor unit when the heat exchanger of the indoor unit is installed horizontally. .

As illustrated in FIG. 2A, when the heat exchanger 10 of the indoor indoor unit is installed horizontally, a plurality of water collection guides 12 and front grills may be collected to collect condensate generated on the surface of the heat exchanger 10. 11) is formed integrally or the collection guide portion 12 is attached to the front grill is installed under the heat exchanger 10. The front grill is formed with an air inlet to correspond to the heat exchanger, the air outlet is formed in the rim portion Is formed.

In addition, a drain 13 for collecting the condensed water collected by the collecting guide part 12 and draining it to the outside is installed at one end of the collecting guide part 12.

In addition, the drainage portion 13 is formed in the condensate inlet 15 corresponding to each of the collection guide portion 12 on the side coupled to the collection guide portion 12 so that the condensate on the collection guide portion 12 is introduced, In addition, a drain hose 16 for draining the condensed water introduced through the inlet 15 to the outside is installed at the side of the drain 13.

On the other hand, the collection guide portion 12 is a bar-shaped cross-section is formed in the shape of a groove so that when the condensate on the heat exchanger 10 falls into the front grill (11). These collection guides 12 are provided between the suction openings 14 of the front grill, respectively.

As shown in FIG. 2B, the grooves of the water collecting guide part 12 have a V-shaped cross section having both sides 17 inclined, and are continuously formed in the longitudinal direction of the water collecting guide part 12, and are collected in the drainage part 13. To guide.

Meanwhile, as illustrated in FIG. 3C, the water collecting guide portion 12 has a groove depth deeper toward the drainage portion so that the guide of the condensate is smoothly formed, and the groove is inclined in the longitudinal direction of the water collecting guide portion 12. Has

In addition, the collection guide portion 12 is disposed side by side between the intake port 14 so as not to block the air intake port 14 of the front grill 11 is installed on the front grill 11 or the front grill 11 and It is formed integrally.

Since the water collecting guide part 12 of the first embodiment is disposed at intervals as much as the inlet port 14 so that the sucked air passes in the heat exchanger 10 direction, the condensed water is sucked by the suction force when the air is sucked from the indoor unit. Although it does not flow out to the suction port 14, when the suction operation of the indoor unit is stopped, condensed water contacting the surface may be collected and discharged to the suction port 14 by the surface tension of the heat exchanger 10.

Thus, a second embodiment which solves the problem of the first embodiment will be described with reference to the drawings.

As shown in FIG. 3A, the coupling state of the plurality of collecting guide parts 20 and the drainage part 13 formed together with the front grill 11 is almost the same, but the groove cross-sectional shape of the collecting guide part 20 is changed. And accordingly, the arrangement interval of the collection guide portion 20 is also different.

As shown in FIG. 3B, the water collecting guide portion 20 is formed with inclined surfaces 21a and 21b having different lengths on both sides.

That is, it is a case where the length of one inclined surface 21b is formed longer in V-shaped cross-sectional shape.

It is installed on the front grill 11 by overlapping each other such that the inclined surface 21a of the other collecting guide portion 20 is positioned below the inclined surface 21b of the long collecting guide portion 20 formed as described above. It is formed integrally.

Each of the water collecting guides 20 is disposed at regular intervals such that the inclined surfaces do not contact each other so that the air sucked between the inclined surfaces 21a and 21b overlapping each other.

Then, as shown in FIG. 3B, since the inclined surfaces of the water collecting guide portion 20 directly above and below the suction port 14, the condensed water of the heat exchanger 10 may flow out through the suction port 14. In addition to blocking the path that can be passed through the inlet 14 can also ensure the passage of air.

On the other hand, the drain portion 13 is installed in the same manner as in the first embodiment.

In addition, as in the first embodiment, the water collecting guide portion 20 of the second embodiment also has a deeper groove depth toward the drainage portion 13 so as to guide the condensate more smoothly, as shown in FIG. 3C of the first embodiment. As described above, the groove has an inclined shape in the longitudinal direction of the collecting guide portion 20.

On the other hand, in the second embodiment, although the condensed water does not flow out into the room through the inlet 14, the air flowing through the inlet 14 is redirected by the inclined surface of the water collection guide 20. Since it moves to the heat exchanger 10, friction occurs between the inclined surface and the air, causing noise and reducing suction efficiency.

In addition, the water collecting guide portion 20 of the second embodiment is not easy to manufacture compared to the water collecting guide portion 12 of the first embodiment formed symmetrically, in particular, the water collecting guide portion 20 and the front grill 11 In the case of integrally fabricating the mold, there is a problem in that mold design and departure from the mold are difficult.

Accordingly, the third embodiment will be described with reference to the drawings as the most preferred embodiment which solves the problems of the first and second embodiments.

As shown in FIG. 4A, the coupling state of the collecting guide part 30 and the draining part 13 formed together with the front grill is almost the same, but the collecting guide part 30 protrudes in the center of the collecting protrusion 31. Is formed to have a different cross-sectional shape.

As shown in FIG. 4B, the grooves of the collecting guide portion 30 are similar to the V-shaped cross-sections of which both sides are inclined, and the collecting protrusion 31 has a length in contact with the surface of the heat exchanger 10 at the center of the V-shaped groove. ) Is protruding.

In addition, the catching protrusion 31 is reduced in width toward the top thereof, and has a shape such as a sharp tip.

On the other hand, the drain portion 13 is installed in the same manner as in the first embodiment.

In addition, as in the first embodiment, the water collecting guide portion 30 of the third embodiment also has a deeper groove depth toward the drainage portion 13 so that the condensate can be guided more smoothly, as shown in FIG. 3C. The groove has a form inclined in the longitudinal direction of the guide portion 30.

In addition, the collecting guide part 30 is disposed side by side between the suction ports 14 so as not to block the suction port 14 of the front grill 11, and is installed on the front grill 11 or integrally with the front grill 11. Is formed.

Referring to the drawings the operation of the third embodiment configured as described above is as follows.

As shown in FIG. 4B, the air sucked through the suction port 14 of the front grill 11 is introduced into the heat exchanger 10 through the collection guide part 30 without any interference, and the heat exchanger Condensed water is generated on the surface of the heat exchanger 10 during the process of heat exchange of air at 10.

The condensed water is formed in contact with the surface of the heat exchanger 10 by the surface tension of the heat exchanger 10, or the condensed water is in contact with the surface of the heat exchanger 10 by the air introduced through the inlet 14. Flows.

Then, the collecting protrusion 31 of the collecting guide part 30 in contact with the surface of the heat exchanger 10 guides the condensed water flowing along the surface of the heat exchanger 10 to the groove of the collecting guide part 30. The condensed water guided into the groove of the collecting guide part 30 is drained to the drain 13 installed at the end of the collecting guide part 30 along the longitudinally inclined groove.

Meanwhile, even when no air is introduced into the heat exchanger 10, the surface tension of the heat exchanger 10 is continuously formed on the surface of the water collecting protrusion 31 of the water collecting guide 30. The excess condensate remaining on the surface of the water does not fall toward the front grill (11) flows into the water collecting projections 31 are collected in the groove of the water collecting guide portion (30).

That is, condensate located between the ends of the catching protrusions 31 in contact with the heat exchanger 10 flows to the ends and collects into the catching protrusions 31 before falling to the front grill by gravity.

The third embodiment which acts as described above is a problem of the first embodiment in which the condensed water may be discharged to the suction port and the second embodiment in which the collecting guide part interferes with the air intake and may reduce noise and suction efficiency. Condensate can be collected and discharged completely without this occurrence.

However, since the cross-sectional shape of the collecting guide portion of the third embodiment is slightly more complicated than other embodiments, the above embodiments can be selectively used according to the type and installation location of the ceiling type air conditioner.

As described above, the present invention easily solves the problem that the condensed water can be discharged to the room when the heat exchanger of the indoor unit is installed horizontally, the air heat exchange rate is reduced while the thickness of the indoor unit is limited to the height located on the ceiling It is possible to manufacture a ceiling type indoor unit which is increased and low production cost.

In addition, since it is possible to install and utilize the water collecting device of the present invention without greatly modifying the structure of the conventional ceiling-type indoor unit, manufacturing cost for new product development can be reduced.
