In the following description, for purposes of explanation, specific details are set forth to provide a thorough understanding of the application. It will be apparent to one skilled in the art, however, that the present application can be practiced without using these specific details. In other instances, well-known structures and processes are not elaborated in order not to obscure the description of the present application with unnecessary details. Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded with the widest scope consistent with the principles and features disclosed.

[0034] As Figures 1 to 3 shown, the embodiment of the present application provides a seat crane 100, which comprises a machine shell 1, an air outlet assembly 102 and an air duct seat 3, and can facilitate maintenance actions such as maintenance, cleaning and the like on the seat crane 100, and improve the convenience of after-sales service.

[0035] The machine shell 1 is provided with an air outlet 1A, which is opened on the surface of the machine shell 1, and the inside of the machine shell 1 can be provided with functional components such as a heat exchanger, the air duct seat 3, a fan 4 and the like. The air outlet assembly 102 is arranged at the air outlet 1A and is detachably mounted on the air duct seat 3.

[0036] Compared with the related art, the seat crane 100 provided by the embodiment of the present application is provided with a detachable air outlet assembly 102, which can be conveniently detached from the air duct seat 3 to expose the internal space of the machine shell 1; and then, the operator can conveniently perform maintenance actions such as maintenance, cleaning, replacement and the like on the detached air outlet assembly 102 and other functional components located in the machine shell 1, thereby effectively improving the convenience of after-sales service.

[0037] As Figures 1 to 6As shown, in some embodiments, the pedestal crane 100 may include a fan 4. The air duct seat 3 is used to carry and install the fan 4. The type of the fan 4 can be determined according to actual needs, and can be, for example, a cross-flow fan 4, a centrifugal fan 4, or other different types, and the embodiment of the present application does not limit this. The fan 4 can include blades 41, and the type of the blades 41 can be determined according to actual needs, and can be, for example, a cross-flow blade 41, a centrifugal blade 41, or other different types, and the embodiment of the present application does not limit this. In some embodiments, the fan 4 can be a cross-flow fan 4, and the blades 41 can be cross-flow blades 41.

[0038] Here, the air outlet assembly 102 may include a first side wall 21, a second side wall 22, and a third side wall 23. Exemplarily, the air outlet assembly 102 may include an air outlet frame 2, and the first side wall 21, the second side wall 22, and the third side wall 23, as well as the following structures, may be formed on the air outlet frame 2. The first side wall 21 and the second side wall 22 are spaced apart to form an air outlet cavity 2A. The third side wall 23 and the first side wall 21 are obliquely connected to form a volute tongue 2C. The air duct seat 3, the volute tongue 2C, and the second side wall 22 enclose an air duct cavity 3A. The air duct cavity 3A and the air outlet cavity 2A are connected in sequence. The fan 4 includes blades 41, and the air duct cavity 3A is used to accommodate the blades 41. When assembling the fan 4, the fan 4 can be first mounted on the duct seat 3, and then the air outlet assembly 102 can be mounted on the duct seat 3, so that the duct seat 3, the volute tongue 2C, and the second side wall 22 enclose the air duct cavity 3A, so that the fan blades 41 can be safely and reliably located in the air duct cavity 3A. When maintaining the fan 4, the air outlet assembly 102 can be first removed from the duct seat 3, exposing the fan 4 to the outside, making it easier to clean, inspect, and perform other maintenance operations on the fan 4.

[0039] In some examples, one end of the air outlet assembly 102 can extend through the air outlet 1A and into the housing 1 to be fixedly connected to the air duct base 3. The end of the air outlet assembly 102 away from the air duct base 3 is placed at the end of the air outlet 1A, so that the air outlet end 2A3 and the air outlet 1A are arranged in a corresponding manner. After the air outlet assembly 102 and the air duct base 3 are removed, the air outlet assembly 102 can be separated from the housing 1 through the air outlet 1A, exposing the fan blades 41 within the range of the air outlet 1A.

[0040] In this way, when the air outlet component 102 or the fan blades 41 need to be cleaned and maintained, the air outlet component 102 can be removed from the air duct seat 3, and then the air outlet component 102 can be pulled out of the casing 1 from the air outlet 1A to expose the fan blades 41 to the outside. The disassembled air outlet component 102 can be thoroughly cleaned or repaired, and the fan blades 41 can be cleaned, inspected and other maintenance operations can be performed through the air outlet 1A, thereby improving the convenience of after-sales maintenance.

[0041] Exemplarily, after the fan blade 41 is exposed to the range of the air outlet 1A, the fan blade 41 can be pulled out of the air outlet 1A to the outside of the casing 1 to clean and maintain or replace the fan blade 41 more thoroughly. Compared with the related art, the crane 100 provided by the embodiment of the present application only needs to disassemble the air outlet assembly 102 from the air duct seat 3 and pull out the air outlet assembly 102 from the air outlet 1A, so that the functional components such as the fan blade 41 inside the casing 1 can be maintained, and the convenience of after-sales maintenance is effectively improved.

[0042] Exemplarily, the casing 1 can be partially disassembled first to expose the air outlet assembly 102 outside the casing 1; then the air outlet assembly 102 is disassembled from the air duct seat 3, and the air outlet assembly 102 is separated from the casing 1, so that the fan blade 41 is exposed to the outside, to clean and maintain the air outlet assembly 102 or the fan blade 41, and improve the convenience of after-sales maintenance.

[0043] In some examples, the air outlet cavity 2A can include a connecting section 2A1, a diffuser section 2A2, and an air outlet end 2A3. The air duct cavity 3A, the connecting section 2A1, the diffuser section 2A2, and the air outlet end 2A3 are sequentially communicated, and the flow area of the diffuser section 2A2 increases from the end of the connecting section 2A1 to the air outlet end 2A3. By providing the diffuser section 2A2, the air duct structure can be optimized, the turbulent vortex at the air outlet end 2A3 can be reduced, and the air outlet volume and efficiency can be improved.

[0044] In some examples, the air duct seat 3 can be provided with a bearing step portion 34 for bearing the air outlet assembly 102. By providing the bearing step portion 34, the positioning and docking area between the air duct seat 3 and the air outlet assembly 102 can be increased, and the assembly precision and connection stability of the air duct seat 3 and the air outlet assembly 102 can be improved.

[0045] Here, the bearing step portion 34 can be provided with a first plug-in hole 341, and the air outlet assembly 102 can be provided with a first plug-in flange 24, which is inserted into the first plug-in hole 341 to connect and fix the air duct seat 3 and the air outlet assembly 102. By providing the plug-in structure, the quick installation and disassembly between the bearing step portion 34 and the air outlet assembly 102 can be achieved. The number of the first plug-in hole 341 and the first plug-in flange 24 can be determined according to actual needs, and each can be one or more, which is not limited in the embodiment of the present application. Exemplarily, the bearing step portion 34 can be provided with a plurality of first plug-in holes 341, and the air outlet assembly 102 can be provided with a plurality of first plug-in flanges 24, which are plugged in one-to-one correspondence, and the reliable connection between the bearing step portion 34 and the air outlet assembly 102 is achieved through the plurality of plug-in structures.

[0046] In some examples, the air duct seat 3 can be provided with a first screw hole 38, and the air outlet assembly 102 can be provided with a protruding arm portion 26 extending outward from the surface of the air outlet assembly 102, and the protruding arm portion 26 is provided with a screw through hole 261. When the air outlet assembly 102 and the air duct seat 3 are assembled, the protruding arm portion 26 can be attached to one side surface of the air duct seat 3, and a fastening screw (not shown in the figure) can pass through the screw through hole 261 and the first screw hole 38 to be fixed, so as to fasten the air duct seat 3 and the air outlet assembly 102.

[0047] In some examples, the air duct seat 3 can be provided with a first screw hole 38, and the air outlet assembly 102 can be provided with a protruding arm portion 26 extending outward from the surface of the air outlet assembly 102, and the protruding arm portion 26 is provided with a screw through hole 261. When the air outlet assembly 102 and the air duct seat 3 are assembled, the protruding arm portion 26 can be attached to one side surface of the air duct seat 3, and a fastening screw (not shown in the figure) can pass through the screw through hole 261 and the first screw hole 38 to be fixed, so as to fasten the air duct seat 3 and the air outlet assembly 102.

[0048] In some examples, the cabinet 1 can include a chassis 12, two side plates 15, a panel 11, an end cover 13 and two side covers 14. The two side plates 15 are arranged on opposite sides of the chassis 12 along a first direction, and the two side covers 14 are respectively arranged on the two side plates 15. The chassis 12, the panel 11 and the two side plates 15 form a main cavity 1B. The air duct seat 3 is arranged in the main cavity 1B, and the air duct seat 3 is connected and fixed to the chassis 12. The air outlet assembly 102 is connected to the two side plates 15, forming a multi-connection structure of an assembly chain, effectively increasing the connection reliability and stability. The end cover 13 is connected and fixed to the air duct seat 3, so that the end cover 13 and the chassis 12 are arranged in sequence along the depth direction of the air outlet 1A, and then the two side covers 14, the panel 11 and the end cover 13 form the air outlet 1A. The two side covers 14 are respectively located between the panel 11 and the end cover 13. The air outlet 1A and the main cavity 1B are sequentially communicated along the depth direction of the air outlet 1A. In this way, the structure can be relatively simple, that is, the inner frame structure is formed by the chassis 12 and the two side plates 15, and the outer decorative structure is formed by the panel 11, the end cover 13 and the two side covers 14. When maintenance is required, one or more components in the outer decorative structure can be disassembled to expose the internal frame structure and the functional components arranged on the internal frame structure.

[0049] As shown in Figures 1 to 7 , for example, the chassis 12 can be provided with a first buckle portion 121 and a second buckle portion 122 arranged at intervals. The air duct seat 3 is provided with a third buckle portion 35 and a fourth buckle portion 36 on opposite sides along a second direction. The first buckle portion 121 and the third buckle portion 35 are buckled, and the second buckle portion 122 and the fourth buckle portion 36 are buckled, so that the air duct seat 3 is installed on the chassis 12. The second direction is perpendicular or inclined to the extension direction of the rotating shaft of the fan blade 41. One of the first buckle portion 121 and the third buckle portion 35 is a male buckle portion, and the other is a female buckle portion. Similarly, one of the second buckle portion 122 and the fourth buckle portion 36 is a male buckle portion, and the other is a female buckle portion. By arranging the above buckling structure, the air duct seat 3 can be conveniently buckled and fixed to the chassis 12, realizing quick positioning and connection between the air duct seat 3 and the chassis 12. The air duct seat 3 can be installed on or disassembled from the chassis 12 along the depth direction of the air outlet 1A, simplifying the installation and disassembly steps of the air duct seat 3.
