The right drive box is mounted on the right end of the bottom case.

Through the above-mentioned mounting structure of the driving box and the bottom case, the driving box can be installed and fixed on the bottom case. When the whole machine needs to be cleaned and disassembled, the driving box can be retained on the bottom case of the non-removing piece without disassembling the driving part of the charging part. , can greatly reduce the amount of disassembly work, and provide convenience for cleaning and disassembling the whole machine. At the same time, since the drive box is a live part, the structure design eliminates the need to disassemble the drive box, which improves the safety of the operator during the disassembly process.

In order to facilitate the disassembly and maintenance detection of the drive box, the present invention provides a simple maintenance mode of the drive box. Specifically, as shown in FIG. 6 to FIG. 9, the air conditioner of the embodiment further includes a panel body 20, and the panel body 20 is disposed. On the bottom case 10, together with the bottom case 10, an outer casing having an inner cavity is formed; the drive box 40 is disposed in the inner cavity; the drive case 40 is detachably mounted on the bottom case 10, and the panel body 20 is provided with a disassembly drive case The yield structure in which 40 moves.

With the air conditioner of the embodiment, the panel body 20 is provided with a seating structure for escaping the movement of the drive box 40 therebetween. When the drive box 40 is repaired, the side panel 50 is first removed, and the electrical box 60 is removed. At this time, the driving box 40 can be exposed, and the driving box 40 is conveniently removed from the seating structure of the panel body 20, which greatly facilitates the after-sales maintenance inspection of the driving box of the whole machine without removing the panel body and reducing the after-sales. Detect the workload of maintenance.

In the present embodiment, the seating structure is formed at the end of the panel body 20 close to the drive box 40. This facilitates the removal of the drive box from the front of the air conditioner, and then performs maintenance inspection, which greatly facilitates the disassembly and maintenance detection of the drive box. Preferably, the bit structure is a yielding gap. The structure of the bit gap is simple and easy to process.

In the present embodiment, as shown in FIG. 6, the air conditioner further includes a side plate 50 detachably disposed at one end of the bottom case 10 and located outside the drive case 40, and the side plate 50 has a parallel to the panel body 20. And a sub-board extending toward the panel body 20, the sub-plate extending to a position covering the drive box 40. The extended front end of the sub-panel cooperates with the side of the panel body 20.

The operation process of detecting and repairing the drive box will be described below. By optimizing the structure of the panel body, a gap is provided on the panel body to facilitate the removal of the drive box from the front side, and the drive box is tested and repaired. First remove the side panel, then remove the electrical box, then the drive box can be completely exposed (as shown in Figure 6), and then the drive box is removed for maintenance testing. The above structure does not need to disassemble the panel body when the drive box is inspected, and only needs to disassemble the side plate and the electrical box, which greatly facilitates the disassembly of the drive box, greatly facilitates the after-sales maintenance detection of the drive box of the whole machine, and the drive box of the whole machine The inspection and maintenance provides great convenience.

Based on the consideration of easy disassembly and easy maintenance of the modular air conditioner, the present invention designs a layout form of the outlet motor and the electrical box.

The above structure leaves a passage for facilitating the removal of the motor from the side of the air conditioner, and facilitates the extraction of the air outlet motor from the side of the air conditioner. During the disassembly process, the outlet motor does not interfere with the drive box, which facilitates the disassembly and maintenance of the motor.

In this embodiment, the driving box 40 is disposed on a side of the outlet motor 30 away from the bottom case 10 and opposite to the bottom case 10; the bottom of the driving box 40 adjacent to the outlet motor 30 has an inward recess recessed therein. The relief groove forms a relief structure 46. That is, when the air conditioner is mounted on the wall surface, the drive box 40 is located directly in front of the air outlet motor 30. The structure of the avoiding groove is simple and easy to process. Preferably, the groove wall of the escape groove has an arched structure. The arched structure facilitates processing and reduces manufacturing costs. Of course, the shape of the groove wall that avoids the groove is not limited thereto.

In the present embodiment, as shown in Fig. 14, the outlet motor 30 and the drive box 40 are both mounted on the boss 11. The boss 11 is increased in height to facilitate the mounting of the drive box and the outlet motor.

In the present embodiment, the drive housing 40 is mounted on the boss 11 on both sides of the escape groove. This makes it easy to mount the drive box on the boss, which makes the fixing more stable and stable.

In the present embodiment, the wind motor 30 is mounted on one of the two bosses 11, and the side of the boss 11 adjacent to the drive box 40 has a mounting position 115 for mounting the wind motor 30. The mounting position 115 facilitates the installation of the wind motor and simplifies the structure of the drive box. Preferably, the mounting location 115 is a mounting recess. The mounting groove is adapted to the shape of the outlet motor.

The following describes the operation process of detecting and repairing the motor. The drive box is installed on the side of the air outlet motor near the front of the air conditioner. The bottom of the drive box near the outlet motor has an arched relief groove to avoid the groove formation. Remove the disassembly passage of the wind motor from the side of the air conditioner. When testing and repairing the outlet motor, first remove the side panel and then remove the electrical box. At this time, the motor end cover is exposed and the motor end cover is removed. Screw, remove the motor end cover to remove the wind motor. In the process of extracting the motor from the side of the air conditioner, the drive box does not interfere with the motor, which greatly facilitates the disassembly and maintenance of the motor, and the maintenance of the motor does not require disassembly of the parts, which is convenient to disassemble. The motor reduces the workload of maintenance personnel.
