Acold wind chamber 41 is positioned above thewind exhausting openings 40, having awind inlet 410 and having one side provided withplural positioning members 411 to be screwed withbolts 7 secured on an upper floor so as to fix thecold wind chamber 41 thereon. - The
housing 9 receiving a motor fan therein is hung on the outer side of thewind inlet 410 of thecold wind chamber 41. Thehousing 9 has its left and right side respectively bored with a throughhole 90, with the left throughhole 90 aligned to thewind inlet 410 of thecold wind chamber 41 and the right one connected with thewind outlet 10 of the return-wind box 1 by awind duct 6. Further, thehousing 9 has one side provided withplural positioning members 91 to be screwed withbolts 7 secured on an upper floor so as to fix thehousing 9 thereon. - Thus, air in a room passes through the return-
wind faceplate 2 and, after filtered, gets into the return-wind box 1 to be condensed into cold air by theevaporator 3. Subsequently, the cold air is sent into thecold wind chamber 41 through thewind outlet 10 of the return-wind box 1 and then forcefully blown outward through thewind exhausting openings 40 of thewind exhausting faceplate 4 by themotor fan 5, letting the cold air circulate quickly in a room, able to economize energy source and having effect of cooling a room evenly. - A sixth preferred embodiment of an air conditioner in the present invention, as shown in
FIG. 8 , includes a return-wind box 1, a return-wind faceplate 2, at least oneevaporator 3, at least onewind exhausting faceplate 4 and at least onemotor fan 5 combined together. - The return-
wind box 1 is provided with at least onewind outlet 10 and has its front and rear side respectively provided withplural positioning members 11 to be screwed withbolts 7 secured on an upper floor so as to fix the return-wind box 1 thereon. - The return-
wind faceplate 2 assembled with the return-wind box 1 is provided with a return-wind inlet 20 having a filter screen provided therein. - The
evaporator 3 is installed in thehousing 9, which is hung on the outer side of thewind outlet 10 of the return-wind box 1. Theevaporator 3 is provided with amoisture collecting tray 30 at the bottom, and thehousing 9 has its opposite sides respectively bored with a throughhole 90 for fitting awind duct 6 and also has one side provided withplural positioning members 91 to be screwed withbolts 7 secured on an upper floor so as to fix thehousing 9 thereon. - The
wind exhausting faceplate 4 is connected with the throughhole 90 of thehousing 9 by awind duct 6, havingwind exhausting openings 40. Acold wind chamber 41 is positioned above thewind exhausting openings 40, having awind inlet 410 for fitting one end of thewind duct 6, which has the other end fitted with thewind outlet 10 of the return-wind box 1. Thecold wind chamber 41 has its opposite sides respectively provided withplural positioning members 411 to be screwed with bolts secured on an upper floor so as to fix thecold wind chamber 41 thereon. - At least one
motor fan 5 is installed in the return-wind box 1. - Thus, air in a room is forcefully sucked into the return-
wind box 1 by themotor fan 5 and condensed into cold air by theevaporator 3. Subsequently, the cold air is sent to thewind exhausting faceplate 4 through thewind outlet 10 of the return-wind box 1 and then blown outward through thewind exhausting openings 40. The number of theevaporators 3 can be increased or decreased according to the size of an indoor space in order to let cold air circulate quickly in a room, able to save energy source and having excellent effect of cooling room evenly. - While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
