[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0048] Combine Figures 1 to 7As shown, the present application provides a fan assembly 200, including a first volute 210, a second volute 220 and an air outlet frame 230. The first volute 210 includes a vertically extending air inlet plate 211 and an annular air inlet shell 212 fixed to one side of the air inlet plate 211. The air inlet plate 211 is provided with a fan inlet 201, and the annular air inlet shell 212 is provided with a first opening. The second volute 220 is snap-fitted and connected to the annular air inlet shell 212 and encloses the installation space of the air outlet wheel. The second volute 220 is provided with a second opening, which is arranged corresponding to the first opening and together constitutes the fan outlet 202. The air outlet frame 230 is arranged at the top of the air inlet plate 211 and snap-fitted with the second volute 220. The air outlet frame 230 is provided with an air flow outlet corresponding to the fan outlet 202, wherein the air outlet frame 230 and the air inlet plate 211 are integrally formed.

[0049] In this solution, the fan assembly is an indoor fan assembly in a mobile air conditioner, and is arranged in the indoor heat exchange cavity of the mobile air conditioner.

[0050] Optionally, the air inlet plate 211 and the annular air inlet housing 212 are integrally formed to improve structural stability and enhance installation efficiency of the fan assembly. Alternatively, the air inlet plate 211 and the annular air inlet housing 212 are fixedly connected by welding, gluing, or other methods.

[0051] In this embodiment, the air inlet plate 211 connects the annular air inlet housing 212 and the air outlet frame 230. The annular air inlet housing 212 is located on the inner side of the air inlet plate 211, and the air outlet frame 230 is located at the top of the air inlet plate 211, above the annular air inlet housing 212. In other words, the air outlet frame 230 and the annular air inlet housing 212 are both located on the inner side of the air inlet plate 211. When the second volute 220 is engaged with the annular air inlet housing 212, the first and second volutes 210, 220 enclose a rotor installation space, in which the fan rotor can be installed.

[0052] The air inlet plate 211 is provided with a fan inlet 201, and an annular air inlet housing 212 is arranged around the fan inlet 201. The annular air inlet housing 212 and the second volute 220 are respectively provided with a first opening and a second opening arranged in a corresponding manner. The first opening and the second opening together constitute the fan outlet 202. Driven by the impeller, air flows sequentially through the fan inlet 201 and the fan outlet 202. By integrally forming an air outlet frame 230 on the air inlet plate 211, a gap is avoided in the middle of the air outlet frame 230, so that the airflow outflowing from the fan assembly 200 flows out through the airflow outlet 231, thereby reducing airflow loss and improving the air output effect.

[0053] When adopting the above technical solution, by integrally forming the first volute with the air outlet frame, a gap in the middle of the air outlet frame is avoided, allowing the airflow from the indoor fan to flow through the air outlet to the indoor air outlet, thus avoiding airflow loss and improving the air outlet effect. Furthermore, the number of parts is reduced, which helps to reduce the number of assembly steps, thereby improving assembly efficiency and further enhancing the stability of the fan assembly installation.

[0054] In the optional embodiment of the above mobile air conditioner, combined with Figure 2 As shown, the fan assembly 200 also includes a mounting slot 241 and a mounting buckle 242 that are snap-fitted to each other, one of the mounting slot 241 and the mounting buckle 242 is arranged on the annular air inlet shell 212, and the other of the mounting slot 241 and the mounting buckle 242 is arranged on the second volute 220.

[0055] In this way, the snap-fitting engagement between the mounting slots 241 and the mounting clips 242 enables stable installation of the second volute 220 and a detachable connection between the second volute 220 and the annular air inlet housing 212, facilitating replacement, cleaning, and maintenance of the second volute 220. Preferably, a plurality of mounting clips 242 are disposed at intervals around the circumference of the annular air inlet housing 212, on the end of the annular air inlet housing 212 facing the second volute 220. The mounting slots 241 and mounting clips 242 are correspondingly disposed on the outer circumferential surface of the second volute 220. The mounting clips 242 are inserted into the mounting slots 241 and snapped into place therein.

[0056] Alternatively, the mounting slot and the mounting buckle are not provided.

[0057] Alternatively, the annular air inlet housing 212 and the second volute 220 are fixedly connected, for example, by welding, gluing, or screwing.

The position-limiting mounting portion 250 is arranged around the outer circumference of the annular air inlet housing 212. One end of the position-limiting mounting portion 250 extends toward the air inlet plate 211. A mounting gap 251 is formed between the other end of the position-limiting mounting portion 250 and the outer circumference of the annular air inlet housing 212. The second volute 220 can be inserted into the mounting gap 251.

[0059] By disposing the position-limiting mounting portion 250 , an installation gap 251 can be formed to determine the locking installation position of the second volute 220 .

In this way, the position-limiting mounting portion 250 can also play a role in strengthening the connection, thereby improving the structural strength of the connection between the annular air inlet housing 212 and the air inlet plate 211.

[0062] Alternatively, one end of the position-limiting mounting portion 250 is not fixedly connected to the air inlet plate 211. In this way, the position-limiting mounting portion 250 can play a role in strengthening the structural strength of the annular air inlet housing 212.
