In addition, the machine body 10 includes a casing, the casing has an air outlet, and the air outlet of the casing is opposite to the air outlet of the upper air outlet duct 241 and the air outlet of the lower air outlet duct 242; the air outlet of the shell is provided with a sliding plate 14, and the sliding plate 14 is used for sealing the air outlet of the shell or communicating the air outlet of the shell with the outside.
The sliding plate 14 can protect the inside of the machine body 10 when the machine body 10 is not in use, so that dust and other impurities are prevented from entering, and compared with a guide plate, the sliding plate 14 horizontally slides, so that the occupied space of other structures of the machine body 10 in the blowing direction of the air outlet duct can be further reduced, and the whole volume of the machine body 10 of the round cabinet is reduced.
Specifically, in one embodiment, in order to realize the sliding opening and closing of the sliding plate 14, a driving motor is disposed at the top of the casing, and the driving end of the driving motor is connected with the rotating plate of the top plate, so as to drive the rotating plate to rotate, and further drive the sliding plate 14 to rotate and open and close. Of course, in other embodiments, the sliding plate 14 may be opened or closed by other driving methods, which will not be described herein.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
