[0034] Duct air conditioners are usually equipped with filters on the return air side to filter out impurities in the environment. After a long time, the filters will become dirty and clogged and need to be disassembled for cleaning. Currently, filters are of integral and segmented types, and are usually fixed in slots or snaps. Slot-type filters can only be pulled out by sliding left and right, which places high demands on the space for installing the unit. Sufficient space needs to be left at one end of the ceiling inspection port to facilitate the removal of the filter. For snap-on filters, if the unit is too long and the inspection port on the ceiling is not large enough, it will be difficult to reach the filter clips at the far end to remove the filter, which seriously affects the user experience. To this end, the present application provides a method such as Figures 1 to 6The duct air conditioner shown includes: a shell 1, on which a return air port 11 is provided; a filter structure 2, which is arranged at the return air port 11; at least two buckles 3, all of which are movably arranged on the shell 1, and the buckles 3 have a clamping state in which the filter structure 2 is clamped to the return air port 11 and a releasing state in which the filter structure 2 is released; a driving mechanism, which is connected to all of the buckles 3, and the driving mechanism can simultaneously drive all of the buckles 3 to switch between the clamping state and the releasing state. By utilizing the driving mechanism to drive all the buckles 3 to move, the user can directly operate the disassembly and assembly of the filter structure 2 from the driving mechanism, which effectively reduces the difficulty of disassembly and assembly of the filter structure 2. Moreover, the filter is in the shape of a flat plate. After it is removed from the return air outlet 11, the filter can be pulled out and loaded through a smaller opening, and an inspection port can be provided only on the ceiling on one side of the installation position of the duct machine, thereby effectively reducing the number and size of the inspection ports on the ceiling, overcoming the problems of the duct machine in the prior art that the installation space requirement is large and the inspection port is too large, thereby improving the inspection efficiency of the duct machine and reducing the influence of the duct machine on the aesthetics of the decoration.

[0035] When cleaning and repairing the duct machine, the driving mechanism can be used to drive all the buckles 3 to move synchronously, so that the filter structure 2 is separated from the return air port 11, and then the filter structure 2 can be pulled out from the ceiling through the inspection port. Similarly, after cleaning the filter structure 2, the filter structure 2 is inserted into the ceiling through the inspection port and buckled at the return air port 11, and then the driving mechanism is used to drive all the buckles 3 to move in the opposite direction to achieve the fixing of the filter structure 2.

[0036] As an implementation mode, the buckle 3 is hinged at the edge of the return air port 11, and when the buckle 3 is in the snap-fit ​​state, part of the buckle 3 is located within the flow area of ​​the return air port 11 to snap-fit ​​the filter structure 2. That is, the buckle 3 is rotated to snap-fit ​​and disengage the filter structure 2. When the filter structure 2 needs to be snap-fitted, part of the buckle 3 is rotated to the flow area of ​​the return air port 11. Since the filter structure 2 needs to fully cover the flow area of ​​the return air port 11, the snap-fit ​​effect of the filter structure 2 by the buckle 3 can be guaranteed. When the filter structure 2 needs to be disassembled, the buckle 3 will move outside the flow area of ​​the return air port 11, thereby disengaging the snap-fit ​​fixation of the filter structure 2 and facilitating the removal of the filter structure 2.

[0037] Specifically, the driving mechanism includes a moving rod 4, which is movably arranged on the housing 1, and all the buckles 3 are connected to the moving rod 4. The movement of the moving rod 4 drives all the buckles 3 to move. As shown in the figure, one end of the buckle 3 is connected to the moving rod 4, and the middle part of the buckle 3 is hinged to the housing 1. At this time, the other end of the buckle 3 can realize the movement at two positions within the flow area of ​​the return air outlet 11 and outside the flow area of ​​the return air outlet 11.

[0038] In order to prevent the moving rod 4 from moving unexpectedly and causing the filter structure 2 to fall off, a locking structure is provided on the moving rod 4, and the moving rod 4 can be fixed to the shell 1 through the locking structure. When the filter structure 2 does not need to be disassembled, the moving rod 4 is fixed by the locking structure, thereby ensuring that all the buckles 3 are relatively still, and the filter structure 2 can be reliably set at the return air port 11. When the filter structure 2 needs to be disassembled, the locking structure is opened to allow the moving rod 4 to move, and the buckles 3 can be driven to move by the moving rod 4. Preferably, the locking structure is a bolt, and the moving rod 4 can be locked by the threaded fit between the bolt and the shell 1. If there is a large resistance during the rotation of the buckle 3, the locking structure may not be provided.

[0039] In order to facilitate the user to operate the driving mechanism, a handle structure 41 is provided on the movable rod 4. The user can directly move the movable rod 4 through the handle structure 41. Optionally, one end of the movable rod 4 is bent to form the handle structure 41. That is, it is convenient to process the handle structure 41, reduce the production cost, and also reduce the structural complexity of the handle structure 41, avoiding the problem of additionally connecting the handle structure 41 to the movable rod 4. Among them, the locking structure can be provided on the handle structure 41, which is convenient for disassembly and assembly of the locking structure.

[0040] The driving mechanism includes a mounting rod 5, which is disposed on the housing 1, and all the buckles 3 are movably disposed on the mounting rod 5. The mounting rod 5 is used to reduce the structural improvement of the housing 1. When in use, the movable rod 4 and all the buckles 3 can be directly mounted on the housing 1 through the mounting rod 5.

[0041] In order to further simplify the structure of the duct machine, the return air outlet 11 has a first edge and a second edge relative to each other, the first edge is provided with the buckle 3, and the second edge is provided with a guide groove 12. That is, the buckle 3 and the driving mechanism are only provided on one side of the return air outlet 11, and the other side only needs to be able to support and limit the filter structure 2. When installing the filter structure 2, the corresponding side of the filter structure 2 can be first slid into the guide groove 12, and then the filter structure 2 can be pushed into the direction of the return air outlet 11. When the filter structure 2 closes the return air outlet 11, the installation of the filter structure 2 can be completed by driving the buckle 3 to move through the driving mechanism, thereby reducing the complexity of the structure and the difficulty of operation and improving the user experience.

[0042] As another embodiment not shown, the buckle 3 and the driving mechanism are provided at the first edge and the second edge of the return air outlet 11. When in use, the buckle 3 can be driven separately, so that the filter structure 2 can be directly removed from the return air outlet 11. When installing, the filter structure 2 is directly buckled on the return air outlet 11, and then the two driving mechanisms are driven separately, thereby further simplifying the operation.

[0043] In order to further reduce the size of the inspection opening, the cross section of the return air port 11 is a rectangle, and all the buckles 3 are arranged in parallel along the length direction of the rectangle. At this time, when disassembling the filter structure 2, it is only necessary to open an inspection opening of the width of the filter structure 2 on the ceiling, thereby minimizing the impact of the inspection opening of the duct machine on the aesthetics of the decoration.

[0044] An air conditioning unit comprises the above-mentioned duct unit.

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
