Therefore, an upper end cover of the upper cover 11 and a part, close to the upper end, of the dome 12 are separated from a cold air in the air conditioning device, and formation of the dews on the top cover assembly 100 is effectively reduced. The upper cover upper plate 111 and the upper cover lower plate 112 are formed separately, and may also be formed as one structure.

[0033] In a preferred embodiment, a decorative structure (not shown in the figures) is formed in the cavity 113, and the decorative structure is a decorative structure in various forms such as a decorative painting, a decorative pattern and a decorative light, and may improve the aesthetics of the appearance of the air conditioning device. Or, a display device (not shown in the figures) is further provided in the cavity 113, and the display device may be a display screen or an illumination device or a combination thereof, so that some working and/or setting information related to the air conditioning device are/is displayed on the upper cover 11, and then the user may learn about a working condition of the air conditioning device more intuitively. When the cavity 113 is formed into the airtight cavity, aging or damage of these decorative structure and display device is effectively reduced, and influence of the cold air in the air conditioning device on structures of these decorative structure and display device is reduced; and in addition, the cold air or hot air produced by the air conditioning device is further prevented from entering the top cover assembly and further entering the inner side of the upper cover 11, and formation of the dews at the upper end of the air conditioning device is effectively prevented.

[0034] For further reducing formation of the dews, a heating device 115 is provided at a position of a radial edge of the top cover assembly 100, and the heating device 115 is a conventional heating structure such as an electric heating wire, and is provided to effectively remove the dews left on the edge of the top cover assembly 100 to improve a user experience.

The sealing ring 120 is fixed on the small end opening of the dome 12, and in such a manner, when the dome slides up and down, the cavity in the dome 12, comprising the cavity 121, is separated from the outside in a sealing manner, so as to be separated from the cold or hot airflow formed in the air conditioning device, then the cold or hot airflow formed in the air conditioning device is prevented from entering the cavity 121, and the cold or hot airflow is prevented from influencing electrical parts such as a motor and a travel switch in the lifting mechanism 13 to influence normal running of the lifting mechanism 13.

[0038] As shown in Fig. 2 and 3, in a preferred embodiment, a sealing structure 143 is provided on the lifting mechanism housing 14. The sealing structure 143 is annular, and comprises a dome sealing part 1431, a lifting mechanism housing sealing part 1432 and a fixing part 1433 which are sequentially connected, and the fixing part 1433 is provided to fix the sealing structure 143 on the lifting mechanism housing 14. The dome sealing part 1431 is provided at a lowermost end, and is preferably a lower end face of the sealing structure 14. A radial inner edge 122 is preferably provided on the small end opening of the dome 12, the radial inner edge 122 extends towards an interior of the dome 12, and under such a condition, the sealing ring 120 is provided on a radial inner side of the radial inner edge 122. When the dome 12 is driven by the lifting mechanism 13 to slide upwards to a position of an uppermost end, an upper end face of the radial inner edge 122 is pressed against the dome sealing part 1431, so that a space in the dome 12 may further be sealed.

[0040] In a running process, particularly a cooling running process, of the air conditioning device, it is very likely to form dews in the vicinity of the air outlet, and even some waterdrops drip, so that the user experience of the user is influenced. In the invention, the independent cavity is provided in the upper end of the top cover assembly, and formation of the cavity may reduce cold air produced in the air conditioning device and even avoid the cold air produced in the air conditioning device entering a position close to the upper end of the top cover assembly, and may effectively reduce formation of dews at an upper part of the top cover assembly; and moreover, the heating device is further provided in the cavity, so that formation of the dews is further reduced. Furthermore, the decorative structure or the display device may further be provided in the cavity, so that the appearance of the air conditioning device is more attractive, and the user may conveniently learn about the running state of the air conditioning device.

[0041] At last, it is important to note that: obviously, the embodiment is intended not to limit the implementation modes but only to clearly describe examples made in the invention. Those skilled in the art may further make variations or modifications in other different forms on the basis of the above descriptions. It is unnecessary and also impossible to exhaust all the implementation modes here. Apparent variations or modifications extended thereby still fall within the scope of protection of the invention.
