Preferably, the airflow diversion receiving chamber is used to change the airflow direction. The airflow diversion receiving chamber of this embodiment can also be said to be a fan assembly receiving chamber, which is used to accommodate the entire fan assembly 1.

[0029] The installation structure of the fan assembly 1 of the present embodiment includes a fan assembly 1 and an air duct assembly 2, and the air duct assembly 2 includes an air duct body 21 and an air duct cover plate 22. The fan assembly 1 is installed on the inner side surface 221 of the air duct cover plate 22 and is located in the air flow deflection receiving cavity formed by the air duct body 21 and the air duct cover plate 22, that is, the fan assembly 1 of the present embodiment is installed on the inner side of the air duct assembly 2, and the outer cavity formed by the air duct body 21 and the air duct cover plate 22 surrounds the entire fan assembly 1, which can not only make the fan assembly 1 fixed firmly and enhance the smoothness of the operation of the fan assembly 1, but also prevent the deformation of the air duct assembly 2 and other factors from affecting the sealing and smoothness of the installation of the fan assembly 1, resulting in resonance and noise problems in the centrifugal fan.

[0030] That is, the installation structure of the fan assembly 1 in this embodiment solves the technical problem in the prior art that the installation method of the fan assembly 1 easily causes resonance and noise in the centrifugal fan by installing the fan assembly 1 on the inner side of the air duct assembly 2 and surrounding the entire fan assembly 1 with an outer cavity formed by the air duct body 21 and the air duct cover 22.

[0031] According to a preferred embodiment, the fan assembly 1 includes a motor, a centrifugal fan blade or an axial flow fan blade, and the centrifugal fan blade or the axial flow fan blade is fixedly connected to the rotating shaft of the motor. Preferably, when the fan assembly 1 is located in the airflow redirection receiving chamber, the centrifugal fan blade or the axial flow fan blade faces one side of the air duct body 21, such as Figure 2 Or as shown in 3. That is, the centrifugal fan blades or axial flow fan blades of this embodiment are arranged toward the air inlet side.

[0032] According to a preferred embodiment, the fan assembly 1 further includes a fan fixing plate 11, the motor is fixed on the fan fixing plate 11, and the fan fixing plate 11 is installed on the inner side 221 of the air duct cover plate 22, such as Figure 2 Or as shown in 3. Preferably, the fan fixing plate 11 is an injection molded part or a sheet metal part. The motor of the preferred technical solution of this embodiment is fixed to the fan fixing plate 11, the centrifugal fan blades or axial flow fan blades are fixedly connected to the rotating shaft of the motor, and the fan fixing plate 11 is installed on the inner side surface 221 of the air duct cover plate 22, so that the entire fan assembly 1 is arranged on the inner side surface 221 of the air duct cover plate 22, that is, the preferred technical solution of this embodiment accommodates the entire fan assembly 1 through the airflow deflection receiving chamber formed by the air duct body 21 and the air duct cover plate 22, which can not only facilitate the fixing and stability of the fan assembly 1 and enhance the smooth operation of the fan assembly 1, but also prevent noise and other problems caused by factors such as deformation of the air duct assembly 2.

[0033] According to a preferred embodiment, the fan fixing plate 11 is provided with a first screw hole 111, the air duct cover plate 22 is provided with a second screw hole 222, and the fan fixing plate 11 and the air duct cover plate 22 are detachably connected through the first screw hole 111 and the second screw hole 222. Figure 3 As shown, the fan fixing plate 11 is provided with a plurality of first screw holes 111 for fixedly connecting with the inner side 221 of the air duct cover plate 22; the air duct cover plate 22 is provided with a plurality of second screw holes 222 for fixedly connecting with the fan assembly 1.

In the preferred technical solution of this embodiment, the upper bottom surface 112 of the fan fixing plate 11 is flush with the inner side surface 221 of the air duct cover plate 22, and the two together form an air duct profile line, which prevents the problem of noise and air leakage caused by the airflow turning to the inner side of the receiving chamber due to the unevenness of the upper bottom surface 112 of the fan fixing plate 11 and the inner side surface 221 of the air duct cover plate 22 (that is, there is a step between the upper bottom surface 112 of the fan fixing plate 11 and the inner side surface 221 of the air duct cover plate 22), and can also prevent the problem of condensation on the outer surface of the air duct.

[0035] According to a preferred embodiment, the installation structure of the fan assembly also includes a seal, which is arranged on the outer side surface of the air duct cover plate 22 and makes the outer side surface of the air duct cover plate 22 flush with the lower bottom surface 113 of the fan fixing plate 11. Preferably, the seal is a sponge. The seal of the preferred technical solution of this embodiment is arranged on the outer side surface of the air duct cover plate 22. On the one hand, the outer side surface of the air duct cover plate 22 can be flush with the lower bottom surface 113 of the fan fixing plate 11; on the other hand, by sticking seals such as sponges, the outer side surface of the air duct cover plate 22 and the lower bottom surface 113 of the fan fixing plate 11 can also form a sealing surface on the back of the airflow deflection receiving chamber, further reducing the problem of weak sealing of the air duct assembly 2 due to injection molding, transportation deformation and other factors.

[0036] The air conditioner of this embodiment includes the installation structure of the fan assembly described in any technical solution of this embodiment. Preferably, the air conditioner of this embodiment is a vertical air conditioner. More preferably, the air duct assembly 2 of the vertical air conditioner of this embodiment is a structure of upper and lower air outlets.

[0037] Since the fan assembly in the prior art is generally installed on the outside of the air duct assembly, when the air duct is easily deformed due to injection molding, transportation, etc., the sealing and stability of the fan assembly installation are affected, thereby causing the overall performance of the air conditioner to decline. Therefore, it is necessary to change the installation position of the existing fan assembly. The air conditioner of this embodiment changes the installation position of the fan assembly 1 while achieving up and down air discharge, and installs it on the inner side 221 of the air duct cover plate 22 and is located in the air flow deflection receiving cavity formed by the air duct body 21 and the air duct cover plate 22, thereby avoiding noise and resonance problems.

[0038] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
