Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of the utility model protection.
The air-cooled ducted air conditioner that the utility model embodiment provides, including: there is the casing 21 of return air inlet 211 and air outlet 212, be positioned at the centrifugal blower 22 of casing 21；Wherein, return air inlet 211 is positioned at the bottom of casing 21, and air outlet 212 is positioned at the front end of casing 21；The air intake 221 of centrifugal blower 22 is relative with return air inlet 211, and the outlet air end 222 of centrifugal blower 22 is relative with air outlet 212.
The air-cooled ducted air conditioner that the utility model embodiment provides, relative with return air inlet 211 by the air intake 221 of centrifugal blower 22, the outlet air end 222 of centrifugal blower 22 is relative with air outlet 212, return air is made to enter centrifugal blower 22 directly from air intake 221 after entering casing 21, directly being discharged by air outlet 212 after centrifugal blower 22, relatively prior art return air could enter blower fan through turnover and compare, and effectively reduces windage, the return air of centrifugal blower 22 smoothly, is effectively increased the operating efficiency of whole air-cooled ducted air conditioner.
Meanwhile, the air-cooled ducted air conditioner that the utility model embodiment provides, directly from air intake 221 after return air entrance casing 21, effectively reduce windage, reduce noise, be effectively increased serviceability.
Simultaneously, in the air-cooled ducted air conditioner that the utility model embodiment provides, the air intake 221 of centrifugal blower 22 is relative with return air inlet 211, the outlet air end 222 of centrifugal blower 22 is relative with air outlet 212, so, compared with the prior art, the height of whole centrifugal blower 22 can be effectively reduced, thus effectively reduce the height of whole air-cooled ducted air conditioner, facilitate installation and the use of air-cooled ducted air conditioner.
