At last, the fourth embodiment of the present invention is described with reference to Figure 14 and 15, wherein, the same numeral in these figure represent with each embodiment shown in above Fig. 1-13 in identical parts.

Figure 14 represents the perspective view of the air-conditioner 10 of the 4th embodiment; From Figure 14 obviously as can be seen, air-conditioner 10 is made of casing (being the main body of air-conditioner 10 itself) and the front panel 200 that is fixed on its front surface.

But (not shown at these) still will be to install compressor, heat exchanger, fan electromotor, fan and electric component with above-mentioned identical mode on base in casing 10.

Yet front panel 200 will be formed with an air intake grid 210, and in both sides, promptly on the left side and the right side of air intake grid 210, is formed with a pair of air outlet slit grid 220.Between the depth H 1 of the height H 2 of air outlet slit grid 220 and air intake grid 210, set up the former relation, i.e. H1＞H2 greater than the latter.In addition, the surface curvature camber of air intake grid 210, promptly the degree of depth (being H1) from the depth H 2 of both sides to the middle body of front panel 200 increases gradually.

Figure 15 represents the cutaway view of the air-conditioner 10 of the 4th embodiment; High-visible as Figure 15, filter 300 is positioned at after the air intake grid 210, and filter guider 310 is located between air intake grid 210 and the filter 300, is used for keeping between them preset distance L.

At above-mentioned structure, because the depth H 2 to air outlet slit grid 220 designs, make its depth H 1 less than air intake grid 210, therefore unlikely cause the phenomenon of what is called " short circuit ", promptly the air (i.e. the air of Leng Que air or heating) of the adjusted mistake of sending from air outlet slit grid 220 directly turns back to air intake grid 210 so that suction once more.Therefore, might under the condition that does not reduce air handling capacity (that is, air cooling or heating efficiency), finish the room air regulatory function.

And then air intlet grid 210 becomes arc, thereby it is bigger to keep the area that sucks air, has reduced flowing resistance.Yet, by means of this structure, also may make the distance L between filter 300 and the air intake grid 210 bigger, and it is bigger to make air suck area, therefore the air capacity or the speed of the wind by air intake grid 210 are slack-off.Promptly; whereby, the wind that passes air intake grid 210 unlikely is absorbed in from the wind that two side outlets 220 blow out, and filter 300 is difficult for stopping up; from reduce air quantity, obtain protection whereby, and allowed to keep for a long time or kept the initial performance of air-conditioner and unlikely reduction.

Though we have illustrated and described several embodiment of our invention, should understand that disclosed embodiment has many changes and modification under the condition that does not depart from scope of the present invention.Therefore, shown in we do not wish to be subjected to here and the constraint of the details of describing, but try hard to cover all this change and modification in the scope that falls into appending claims.
