Optionally, the volute is further provided with a first air inlet, a second air inlet, and an air outlet, and the receiving cavity is respectively communicated with the first air inlet, the second air inlet, and the air outlet. That is to say, the fan assembly is a double-suction fan.

One end of each installation plate is connected to the installation member, and the other end is connected to the inner wall of the volute. That is to say, at least two installation plates form at least two layers of support structures between the installation member and the inner wall of the volute.

[0010] The air flow generating component is installed on the inner wall of the volute through an installation assembly having at least two layers of support structures, so as to improve the installation stability of the air flow generating component, and further enhance the reliability of the fan assembly. Moreover, since at least two layers of support structures are formed between the installation part and the inner wall of the volute, the structural strength of the volute can be significantly increased. Therefore, even if the volute is made of plastic, it can meet the strength requirements for the fall and transportation of the fan assembly.

[0023] Moreover, since the multiple reinforcing ribs are arranged at intervals, compared with the case where the reinforcing ribs form a circumferentially continuous structure, on the premise of ensuring that the volute has sufficient structural strength, it is beneficial to save the material consumption, reduce the production cost of the fan assembly, and also beneficial to reducing the overall mass of the fan assembly.

When a part of the air flow generating member 130 is inserted into the mounting hole 126, the fitting connection between the first connecting portion 125 and the second connecting portion 131 can be realized, so as to realize the reliable assembly between the air flow generating member 130 and the mounting member 121.

[0101] Moreover, since a part of the air flow generating member 130 is embedded in the mounting hole 126, while ensuring the reliable assembly of the air flow generating member 130, it is beneficial to reduce the overall axial dimension of the fan assembly 100, thereby reducing the volume of the fan assembly 100, which is beneficial to reducing the occupied space of the fan assembly 100 in the air conditioner and improving the space utilization rate of the air conditioner.

[0102] As Figure 3 、 Figure 4 and Figure 5 shown, in some embodiments, optionally, the volute 110 is provided with a slit 112, and at least a part of the slit 112 extends along the circumferential direction of the volute 110.

[0103] In this embodiment, it is defined that the volute 110 is provided with a slit 112. Specifically, at least a part of the slit 112 extends along the circumferential direction of the volute 110. It can be understood that the volute 110 is generally prepared by an injection molding method.

[0104] By reserving a slit 112 with a certain width on the volute 110, during the injection molding process of the volute 110, the deformation of the volute 110 can be effectively avoided, which is beneficial to further improving the structural strength of the volute 110, enhancing the reliability after the installation of the air flow generating member 130, and further enhancing the reliability of the fan assembly 100.

[0105] In some embodiments, optionally, at least a part of the volute 110 is a plastic part.

[0106] In this embodiment, it is defined that at least a part of the volute 110 is a plastic part. Specifically, since at least two mounting plates 122 form at least two layers of support structures between the mounting member 121 and the inner wall of the volute 110.

[0107] Since at least two layers of support structures are formed between the mounting member 121 and the inner wall of the volute 110, the structural strength of the volute 110 can be significantly increased. Therefore, even if the volute 110 is set as a plastic part, it can meet the strength requirements of the fan assembly 100 for dropping, transportation, etc.

[0108] In addition, by setting the volute 110 as a plastic part, compared with setting the volute as a metal part in the related art, on the premise of ensuring the strength of the volute 110, the production cost of the volute 110 can be reduced, and thus the production cost of the fan assembly 100 can be reduced.

[0109] As Figure 2 , Figure 3 and Figure 4 shown, in some embodiments, optionally, the volute 110 is further provided with a first air inlet 113, a second air inlet 114 and an air outlet 115, and any one of the first air inlet 113, the second air inlet 114 and the air outlet 115 is communicated with the accommodation cavity 111; along the axial direction of the volute 110, the first air inlet 113 and the second air inlet 114 are respectively located on opposite sides of the accommodation cavity 111.

[0110] In this embodiment, it is defined that the volute 110 is further provided with a first air inlet 113, a second air inlet 114 and an air outlet 115. Specifically, the accommodation cavity 111 is respectively communicated with the first air inlet 113, the second air inlet 114 and the air outlet 115. That is to say, the fan assembly 100 is a double-suction fan.

[0111] Along the axial direction of the volute 110, the first air inlet 113 and the second air inlet 114 are respectively located on opposite sides of the accommodation cavity 111. Optionally, the volute 110 includes a main body, a first side plate and a second side plate. Along the axial direction of the volute 110, the first side plate and the second side plate are respectively located on both sides of the main body in the axial direction. The first side plate, the second side plate and the main body enclose to form the accommodation cavity 111. The air outlet 115 is arranged on the main body, the first air inlet 113 is arranged on the first side plate, and the second air inlet 114 is arranged on the second side plate.

[0112] Specifically, when the air flow generating member 130 works, it can make the air flow enter the accommodation cavity 111 from the first air inlet 113 and the second air inlet 114, and flow out through the air outlet 115.

[0113] As Figure 6 shown, in some embodiments, optionally, the air flow generating member 130 includes a motor 132, a first output shaft 133, a second output shaft 134, a first wind wheel 135 and a second wind wheel 136. Among them, the motor 132 is arranged on the mounting member 121. Along the axial direction of the volute 110, the first output shaft 133 and the second output shaft 134 are respectively arranged on both sides of the motor 132. The first wind wheel 135 is connected to the first output shaft 133 and faces the first air inlet 113, and the second wind wheel 136 is connected to the second output shaft 134 and faces the second air inlet 114.

[0114] In this embodiment, it is defined that the air flow generating member 130 includes a motor 132, a first output shaft 133, a second output shaft 134, a first wind wheel 135 and a second wind wheel 136. Specifically, the motor 132 is arranged on the mounting member 121. Optionally, a second connecting portion 131 is arranged on the outer wall of the motor 132.

[0115] The first output shaft 133 and the second output shaft 134 are respectively located on both sides of the motor 132 in the axial direction, that is to say, the motor 132 is a dual-axis motor.

[0116] The first wind wheel 135 is connected to the first output shaft 133, that is, driven by the motor 132, the first output shaft 133 drives the first wind wheel 135 to rotate. The second wind wheel 136 is connected to the second output shaft 134, that is, driven by the motor 132, the second output shaft 134 drives the second wind wheel 136 to rotate. Specifically, when the motor 132 works, it can make the air flow enter the accommodation cavity 111 from the first air inlet 113 and the second air inlet 114, and flow out through the air outlet 115.

[0117] Since the motor 132 is installed on the inner wall of the volute 110 through the mounting assembly 120 with at least two layers of support structures, the installation stability of the air flow generating member 130 can be improved, and further the reliability of the fan assembly 100 can be enhanced. Moreover, since at least two layers of support structures are formed between the mounting member 121 and the inner wall of the volute 110, the structural strength of the volute 110 can be significantly increased. Therefore, even if the volute 110 is made of a plastic part, the strength requirements for the fan assembly 100 during dropping, transportation, etc. can be met.

[0118] In addition, it can be understood that setting the volute 110 as a plastic part can reduce the production cost of the volute 110 on the premise of ensuring the strength of the volute 110 compared with setting the volute as a metal part in the related art, and further reduce the production cost of the fan assembly 100.
