Here, the air outlet duct 133 forms a flow guiding surface near the upper wall surface of the air inlet 136, so that the air blown out from the air inlet 136 can be guided upwards into the air outlet cavity 118.

Referring to fig. 7, in an embodiment, the fresh air module 130 further includes a HEPA net 135 and a centrifugal fan 134, the HEPA net 135 is installed in the air outlet duct 133, and the centrifugal fan 134 is installed in the air inlet duct 132. Specifically, the centrifugal fan 134 includes a centrifugal rotor and a rotor motor for driving the centrifugal rotor to rotate. The centrifugal wind wheel is used for driving outdoor fresh air to enter from the fresh air inlet 112, and the fresh air is filtered by the HEPA net 135 and then flows into the air outlet cavity 118 from the air outlet duct 133.

The utility model discloses still provide an air conditioner, this air conditioner includes machine 100 in air condensing units and the floor standing air conditioner, the floor standing air conditioner in machine 100 through the refrigerant pipe with the air condensing units is connected. The specific structure of the floor type air conditioner indoor unit 100 refers to the above embodiments, and since the air conditioner employs all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
