[0032] The ducted air conditioner is a hidden type air conditioner installed in the ceiling of the room, which has the advantages of flexible and concealed installation position, saving indoor space, etc. The core components of the ducted air conditioner include the partition plate and the volute, etc. The design and assembly method of these components directly affect the production efficiency, assembly efficiency and final performance of the ducted air conditioner.

[0033] A ducted air conditioner is provided in the related art, the fan of the ducted air conditioner includes an upper volute and a lower volute, the lower volute is integrally formed with a partition plate of the ducted air conditioner, the upper volute is detachably connected with the lower volute and the partition plate, and the contact surface of the upper volute and the lower volute is perpendicular to the plane where the partition plate is located.

[0034] However, in the related art, the upper volute needs to be matched with the lower volute and the partition plate at the same time during the assembly process of the upper volute, the assembly process is relatively complex, and assembly interference may occur, which leads to the problem that the upper volute is not assembled in place, or even the problems of air leakage or unstable structure.

[0035] The present application provides a ducted air conditioner, which can avoid the interference problem that may occur during assembly, and simplify the assembly process of the ducted air conditioner.

[0036] In combination Figure 1 As shown in the drawings, the ducted air conditioner provided by the present application includes a partition plate 100 and a fan 200.

[0037] The fan 200 includes a first volute 201 and a second volute 202.

[0038] The first volute 201 is connected with the partition plate 100, and the second volute 202 is detachably mounted on the side of the first volute 201 away from the partition plate 100.

[0039] In the technical solution, the second volute 202 of the fan 200 is detachably arranged on the side of the first volute 201 away from the partition plate 100, and the first volute 201 and the second volute 202 are arranged in a front-rear matching manner. Compared with the related art, the installation process of the second volute 202 only needs to consider the matching relationship between the second volute 202 and the first volute 201, and does not need to simultaneously consider the multiple matching relationships between the upper volute, the lower volute, and the partition plate as in the related art. In this way, interference problems that may occur during assembly can be avoided, the assembly process of the ducted air conditioner is simplified, and the installation quality and operation reliability of the fan and the ducted air conditioner are improved, which is beneficial to further improving the user experience.

[0040] In some embodiments, the first volute 201 is integrally formed with the partition plate 100.

[0041] By integrally forming the first volute 201 with the partition plate 100, the need for screw connection between the first volute 201 and the partition plate 100 in the traditional design can be reduced. This integrated structure makes the assembly process simpler, reduces the assembly steps and the required manual operation, thereby significantly improving the assembly efficiency. At the same time, the integrated design makes the connection between the first volute 201 and the partition plate 100 more secure, avoiding the loosening or deformation problems that may be caused by screw connection in the traditional design. This integrated structure enhances the mechanical strength and stability of the overall component, especially in long-term operation, effectively reducing component damage or failure caused by vibration or external force. In addition, since the first volute 201 and the partition plate 100 are integrally formed, there is no gap or gap between them due to screw connection in the traditional design. This seamless connection design effectively prevents air leakage, improves the sealing performance of the ducted air conditioner, and thus improves the overall energy efficiency and operation efficiency of the air conditioning system.

[0042] Optionally, in combination with Figure 4 As shown in the drawings, in the case where the ducted air conditioner includes a plurality of fans 200, the first volute 201 of each of the plurality of fans 200 is integrally formed with the partition plate 100.

[0043] Thus, the assembly process can be further simplified, the assembly steps and the required manual operation can be reduced, and the assembly efficiency can be significantly improved. Meanwhile, the integrated design makes the connection between the first volute 201 and the partition plate 100 more compact, avoiding the loosening or deformation problems that may be caused by screw connection in the traditional design. Such an integrated structure enhances the mechanical strength and stability of the overall component, especially in long-term operation, which can effectively reduce the damage or failure of the component caused by vibration or external force. In addition, since the first volute 201 and the partition plate 100 are integrally formed, there is no gap or gap between them due to screw connection in the traditional design. Such a seamless connection design effectively prevents air leakage, improves the sealing performance of the ducted air conditioner, and thus improves the overall energy efficiency and operation efficiency of the air conditioning system.

[0044] In some embodiments, the integrated design is a manufacturing process that refers to the processing of a structure that originally requires assembly of multiple independent components into a whole through a mold and molding technology (such as injection molding). This technology realizes seamless integration of components by eliminating the connection links (such as screws, welding, gluing, etc.) in traditional assembly.

This technology realizes seamless integration of components by eliminating the connection links (such as screws, welding, gluing, etc.) in traditional assembly. Figure 4 As shown in FIG. 1, the ducted air conditioner includes a plurality of fans 200, and the second volute 202 of each fan 200 is integrally formed.

[0046] Thus, the assembly process can be further simplified, the assembly steps and the required manual operation can be reduced, and the assembly efficiency can be significantly improved.

This technology realizes seamless integration of components by eliminating the connection links (such as screws, welding, gluing, etc.) in traditional assembly. Figure 2 As shown in FIG. 1, the ducted air conditioner includes a plurality of fans 200, and the second volute 202 of each fan 200 is integrally formed.

[0052] The motor support 300 is integrally formed with the partition plate 100, which can reduce the steps of separately installing the motor support in the traditional design, reduce the number of parts and assembly steps, thereby simplifying the assembly process, reducing the assembly complexity and labor cost and material cost in the production process, and improving the production efficiency. At the same time, the integrated structure can enhance the mechanical strength of the ducted fan, reduce the risk of part loosening or deformation caused by vibration or external force, thereby improving the stability and durability of the equipment. In addition, the two fans 200 are arranged along the extension direction of the partition plate 100, and the motor support 300 is integrally formed with the partition plate 100, so that the internal structure of the ducted fan is more compact. This compact design not only optimizes the space utilization, but also provides more flexibility for the installation and maintenance of other components. Furthermore, the integrated design reduces the connection points and gaps between components, thereby reducing the noise generated by vibration or airflow disturbance, so that the noise level of the ducted fan during operation is significantly reduced, improving the user experience.

[0053] The motor support 300 is an important component in the ducted fan, mainly used for fixing and supporting the motor to ensure that the motor maintains a stable and reliable working state during operation. The ducted fan includes two fans 200, each fan 200 including an impeller, and the motor mounted on the motor support 300 has two output shafts for driving the impellers of the two fans 200 to rotate.
