Air-conditioning 100 described in this description can be to have the indoor unit that is separated from each other and the split-type air conditioner of outdoor unit, and air-conditioning 100 can only refer to the indoor unit of split-type air conditioner.

With reference to Fig. 1, air-conditioning 100 comprises housing 110, a plurality of heat exchanger 120:121 and 123, fan 130 and guiding elements 210.

Air-conditioning 100 comprises: housing 110, has entrance 111 and outlet 113; Overhead heat exchanger 121, is arranged in housing 110; And lower heat exchanger 123, spaced apart with overhead heat exchanger 121.Lower heat exchanger 123 can be positioned at overhead heat exchanger 121 belows, thereby has the region overlapping with overhead heat exchanger 121.

And air-conditioning 100 also comprises: guiding elements 210, for stopping the space between overhead heat exchanger 121 and the adjacent edge of lower heat exchanger 123; And the member 220 that catchments, be set to guiding elements 210, in order to collect and to discharge condensed water from overhead heat exchanger 121.

Housing 110 forms the profile of air-conditioning 100, and has entrance 111 and outlet 113.

And by making fan 130 runnings in housing 110, air is introduced in housing by entrance 111.Afterwards, air is through being heated or cooled in the process of a plurality of heat exchangers 120, and the air being heated or cooled is thus by exporting 113 outsides that are discharged into air-conditioning.

Entrance 111 can be arranged in housing 110 lower than outlet 113 parts, and fan 130 can be arranged on an outlet side of 113.

A plurality of heat exchangers 120 are by be arranged in housing 110 with the isolated state of fore-and-aft direction along the vertical direction.

With reference to Fig. 1, width (following, to be called X-direction) and short transverse (following, to be called Y direction) that overhead heat exchanger 121 and lower heat exchanger 123 are set to respectively along housing 110 are spaced apart with preset distance.

And, for convenience of description, in the first embodiment, the heat exchanger being located opposite from along the upside of the Y direction in Fig. 1 is called to overhead heat exchanger 121 or the first heat exchanger 121, and the heat exchanger being located opposite from along the downside of the Y direction in Fig. 1 is called to lower heat exchanger 123 or the second heat exchanger 123.

In this case, overhead heat exchanger and lower heat exchanger 121,123 are set to, and when observing heat exchanger 121,123 from entrance 111, both have the region overlapping each other.

That is overhead heat exchanger 121 and lower heat exchanger 123 are set to have along the overlapping region of Y direction.More specifically, with respect to entrance 111, a part for the upside of a part for the downside of overhead heat exchanger 121 and lower heat exchanger 123 is overlapping.

Meanwhile, the maximum length in heat exchanger region is limited by the height H c in the space in the housing 110 of accommodating this heat exchanger.Yet the air-conditioning suggestion of the present embodiment makes a plurality of region overlappings of overhead heat exchanger and lower heat exchanger 121,123, to increase total heat exchange area.

And because heat exchanger 120 is divided into a plurality of heat exchangers 121,123, height L1 and the L2 of overhead heat exchanger and lower heat exchanger 121,123 can reduce respectively.

And overhead heat exchanger and lower heat exchanger 121,123 can be respectively fin tubing heat exchanger.

And, by reducing the height of overhead heat exchanger and lower heat exchanger 121,123, can reduce respectively the amount of the condensed water forming on the surface of overhead heat exchanger and lower heat exchanger 121,123.

Specifically,, if form condensed water at overhead heat exchanger 121 places, condensed water flows down to the downside of overhead heat exchanger 121 under Action of Gravity Field.Thus, the flowing along with condensed water is before the downside of overhead heat exchanger 121 and then increase of condensed water, thus make the heat exchange performance of overhead heat exchanger 121 poor.

Yet, because the air-conditioning of the present embodiment can reduce respectively the height of overhead heat exchanger and lower heat exchanger 121,123, therefore flowing of condensed water can be reduced, thereby the heat exchange performance of overhead heat exchanger and lower heat exchanger 121,123 can be improved respectively.

Meanwhile, importantly can prevent that air is through flowing along the space between X-direction and the spaced overhead heat exchanger 121 of Y direction and the adjacent edge of lower heat exchanger 123 respectively.

Guiding elements 210 is carried out the function that stops the space between overhead heat exchanger 121 and the adjacent edge of lower heat exchanger 123.

And guiding elements 210 is carried out and is guided through the function that air that entrance 111 introduces passes through respectively overhead heat exchanger 121 and lower heat exchanger 123.

That is, even if in the situation that overhead heat exchanger 121 and lower heat exchanger 123 have the region overlapping each other, guiding elements 210 also can be carried out the function of guiding Air Flow, on the whole height L2 with the whole height L1 in overhead heat exchanger 121 and lower heat exchanger 123, carries out suitable heat exchange.

As a modification, guiding elements 210 can comprise: the first connection part 211, is positioned at the upside of lower heat exchanger 123; The second connection part 213, is positioned at the downside of overhead heat exchanger 121; And partition board portion 215, be connected between the first connection part 211 and the second connection part 213, to stop the space between overhead heat exchanger 121 and the adjacent edge of lower heat exchanger 123.

Preferably, the upside close contact of the first connection part 211 and lower heat exchanger 123, and the downside close contact of the second connection part 213 and overhead heat exchanger 121.

In this case, when the upside close contact of the first connection part 211 and lower heat exchanger 123 is when covering this upside, can increase the contact area between the first connection part 211 and heat exchanger 123.

Thus, also can prevent shaking of the guiding elements 210 that causes because of Air Flow.

Partition board portion 215 has the shape of oblique extension between the first connection part 211 and the second connection part 213.

Meanwhile, the member 220 that catchments is set to guiding elements 210, in order to carry out from the function of the surface collection condensed water of overhead heat exchanger 121, and therefore collected condensed water is discharged to the outside of air-conditioning.Collect member 220 and there is at least one osculum 227.

Specifically,, if overhead heat exchanger 121 is used as evaporimeter, the condensed water that surface of overhead heat exchanger 121 forms flows downward under Action of Gravity Field, may flow to the surface of lower heat exchanger 123.

In this embodiment, the member 220 that catchments is collected condensed water from overhead heat exchanger 121, and prevents that condensation flow is to lower heat exchanger 123.That is the osculum 227 from the condensed water of overhead heat exchanger by the member 220 that catchments is directed into drain pan 140.

Thus, by preventing that condensing drip from falling lower heat exchanger 123, can prevent that condensed water because of overhead heat exchanger 121 from making the heat exchange performance variation of lower heat exchanger 123.

And the end of two heat exchangers 120 overlaps each other, preferably, the member 220 that catchments is set to guiding elements 210 in the position of the falling direction of the condensed water corresponding to overhead heat exchanger 121.

For example, the member 220 that catchments can be set to the second connection part 213 of guiding elements 210, the downside close contact of this second connection part 213 and overhead heat exchanger 121.

And the member 220 that catchments can have the space S of holding, make the downside of overhead heat exchanger 121 be arranged in this and hold space, to collect, flow to the condensed water on it.

And the member 220 that catchments can be the unlimited box-like of upside.

That is in order fixedly to hold space S, at least the downside of overhead heat exchanger 121 can be spaced a predetermined distance from the inner peripheral surface of the member 220 that catchments.

And the condensed water that the member 220 that catchments can prevent from dropping to the downside of overhead heat exchanger 121 spills the outside of the member 220 that catchments.

In addition, guiding elements 210 and the member 220 that catchments all have along the extension of the length direction of overhead heat exchanger 121 or lower heat exchanger 123.The length of guiding elements 210 and the member 220 that catchments is identical with the length of the length direction of overhead heat exchanger 121 or lower heat exchanger 123.Thus, the condensed water that drops to the downside of overhead heat exchanger 120 can all be collected in the member 220 that catchments.

With reference to Fig. 3 A and Fig. 3 B, the member 220 that catchments can have the stop part 221 extending towards overhead heat exchanger 121 from holding the bottom of space S.

Stop part 221 is carried out and is stopped without overhead heat exchanger 121 but by holding space S, get around the function of the air of overhead heat exchanger 121.

That is, by guiding air, through the second connection part 213 and the gap between the downside of overhead heat exchanger 121 of guiding elements 210, flow through the upside that holds space S arrival overhead heat exchanger 121, the air that stop part 221 can hold introducing space S is directed to overhead heat exchanger 121 inside.

In this case, stop part 221 can extend to height H p(in the downside adjacency of this At The Height stop part 221 and overhead heat exchanger 121 vertically from holding the bottom of space S).Thus, the air that stop part 221 can hold introducing space S is fully directed to overhead heat exchanger 121.

And with reference to Fig. 3 B, the member 220 that catchments can have the guide portion 223 that is inclined upwardly and extends.

And a side of the member 220 that catchments is connected to the second connection part 213, and opposite side is provided with the guide portion 223 that is inclined upwardly and extends.

Guide portion 223 is carried out following function: by introduced air, the condensed water that the surface from overhead heat exchanger 121 is spilt, towards airflow direction (X-direction Fig. 1), is directed to the inside that holds space S.

In this case, preferably, the upside of guide portion 223 is inclined upwardly and extends to the position higher than overhead heat exchanger 121 downsides.

And if overhead heat exchanger 121 is positioned at the rear of lower heat exchanger 123 with respect to air incoming direction, guide portion 223 can be set to the member 220 that catchments.

Fig. 4 A and Fig. 4 B show cutaway view, and it illustrates respectively another modification of the guiding elements in Fig. 1.

With reference to Fig. 4 A, heat-insulating material 230 can be set to catchment member 220 and guiding elements 210 one of at least on.

The heat-insulating material 230 that is set to the member 220 that catchments stops to be collected in and holds the condensed water of space S and through the heat exchange between the air of lower heat exchanger 123, to prevent that total heat exchange performance from declining.

And, the heat-insulating material 230 that is set to guiding elements 210 be arranged on lower heat exchanger 123 with together with guiding elements 210 between overhead heat exchanger 121, prevent from through the air of lower heat exchanger 123 and be incorporated between the air of overhead heat exchanger 121 heat exchange occurs, thereby improve heat exchange performance.

Meanwhile, the first connection part 211 of guiding elements 210 can with lower heat exchanger 123 close contacts, only to cover a part for the upside of lower heat exchanger 123.

After above-mentioned a plurality of heat exchangers 120 are installed, in the time of in guiding elements 210 is arranged on to air-conditioning, guiding elements 210 can be inserted into and be fixed in the space between above-mentioned a plurality of heat exchanger 120.

That is, if the first connection part 211 only forms the part close contact with the upside of lower heat exchanger 123, reduce the length of the first connection part 211, make the insertion of the guiding elements 210 in the space between overhead heat exchanger and lower heat exchanger 121,123 become easier.

And with reference to Fig. 4 B, the member 220 that catchments can namely can be removed sharp-pointed edge for streamlined, to guide swimmingly the Air Flow with the lower side contacts of the member 220 that catchments, thereby reduce gas-flow resistance.

Preferably, only catchmenting the downside of member 220 can be for streamlined.Similarly, in order to reduce gas-flow resistance, guiding elements 223 also can be for streamlined.

And the member 220 that catchments can have the complementary stop part 225 being arranged between stop part 221 and guide portion 223.Complementary stop part 225 can extend vertically from the bottom of the member 220 that catchments, with a side close contact of the bottom with overhead heat exchanger 121.

With stop part 221 similarly, complementary stop part 225 is carried out the function that blocks air move around overhead heat exchanger 121 by holding space S.And, because complementary stop part 225 has increased the contact area with overhead heat exchanger 121, therefore can prevent shaking of the member 220 that catchments that causes because of air-flow.

Fig. 5 shows the stereogram of another modification of the guiding elements in Fig. 1, and Fig. 6 shows the front view of the air-conditioning with the guiding elements in the Fig. 5 being installed on it.

With reference to Fig. 5 and Fig. 6, guiding elements 210 can have side barrier structure 240 disposed thereon.

And side barrier structure 240 is set to the both sides of guiding elements 210, thereby between the both sides of overhead heat exchanger 121 and lower heat exchanger 123 and the inside of housing 110.

Side barrier structure 240 stops the both sides of an overlapping end of each heat exchanger 121,123, to stop the air-flow through the space G between a plurality of overhead heat exchanger and the both sides of lower heat exchanger 121,123 and the inner side of housing 110.

Guiding elements 210, catchment member 220 and side barrier structure 240 can form a unit.Thus, due to after manufacturing guiding elements 210, catchment member 220 and side barrier structure 240, do not need guiding elements 210, catchment member 220 and side barrier structure 240 again assembles, so can reduce manufacturing process.

And, because guiding elements 210, catchment member 220 and side barrier structure 240 form a unit, therefore by side barrier structure 240 is fixed to housing 110, guiding elements 210 and the member 220 that catchments can be fixed to the inside of housing 110, and guiding elements 210 and the member 220 that catchments need not be respectively fixed to top or lower heat exchanger 121,123 or housing 110.

Now will adopt detailed example to describe aforesaid air-conditioning.

Air-conditioning of the present invention comprises: housing 110; The first heat exchanger 121 and the second heat exchanger 123, be arranged in housing 110; Guiding elements 210, for stopping the gap between the first heat exchanger 121 and the second heat exchanger 123; And the member 220 that catchments, be set to guiding elements 210.

In this case, the second heat exchanger 123 is arranged on the first heat exchanger 121 belows, the first heat exchanger 121 be set to make the top of the second heat exchanger 123 and the bottom of the first heat exchanger 121 overlapping.
