In order to facilitate assembly, the box body 15 is U-shaped. Specifically, the box body 15 includes a bottom plate 11 and side plates 10 fixed on both sides of the bottom plate 11. Correspondingly, the box cover 1 is also U-shaped, that is, the box cover 1 includes a top plate and cover plates fixed on both sides of the top plate. Of course, in order to better seal, a cover plate can also be added between the cover plates on both sides.

[0025] In order to ensure the sealing of the box cover 1 and the box body 15 and to facilitate assembly, an N-shaped side plate 12 is fixed to the edge of the side plate 10, and the box cover 1 is buckled on the side plate 12 and fixed to the side plate 12. During actual assembly, the box cover 1 and the side plate 12 can be bolted together. A second sealing gasket 19 is fixed to the side plate 12. The second sealing gasket 19 can be a gasket (also called a gasket) with a mechanical sealing effect in the prior art. By filling the second sealing gasket 19 between the box cover 1 and the side plate 12, the gap between the box cover 1 and the side plate 12 can be sealed, thereby enhancing the sealing effect of the box cover 1 and the box body 15.

[0026] L-shaped support plates 5 are fixed on both sides of the bottom of the box body 15, and the lower end of the box cover 1 is detachably connected to the support plates 5. After the box cover 1 is buckled onto the side plate 12, the lower end of the box cover 1 extends to the support plates 5 and is bolted to the support plates 5. The provision of the support plates 5 facilitates the connection between the lower end of the box cover 1 and the box body 15, and also facilitates the assembly of the box body 15 onto the outdoor unit or other machinery and equipment.

[0027] The partition 6 is detachably connected to the inner wall of the box body 15. Specifically, a plurality of first support blocks 16 are fixed on the side plate 10. The partition 6 is placed on the first support block 16 and is detachably connected to the first support block 16. In order to ensure the sealing of the partition 6 separation position, the partition 6 is fixed with baffles 7 in the circumference, and the outer wall of the baffle 7 and the bottom of the partition 6 are fixed with first sealing gaskets 18. The first sealing gasket 18 can be a gasket (also called a gasket) with a mechanical sealing effect in the prior art. During assembly, the first sealing gasket 18 is first placed on the first support block 16, and it is ensured that the end of the first sealing gasket 18 is against the inner wall of the side plate 10, and then the partition 6 is pressed on the first sealing gasket 18, and the partition 6 and the first support block 16 are bolted together. Finally, the first sealing gasket 18 is also wedged into the side of the partition 6. When the box cover 1 is subsequently assembled, the first sealing gasket 18 can fill the gap between the partition 6 and the inner wall of the box cover 1 to achieve a better sealing effect.

[0028] The first chamber is used to install the electronic control components. Specifically, the electronic control components can be installed on the side surface of the partition 6 facing away from the bottom plate 11. The partition 6 is provided with a mounting position for the electric control board 8 for installing the electronic control components. Specifically, the mounting position can be a mounting groove opened on the partition 6, or it can be a number of mounting protrusions fixed on the partition 6, as long as it can play a role in positioning the electric control board 8 during installation. In order to avoid the direction error when the electric control board 8 is installed, the mounting position is provided with an anti-mistake mark. Specifically, taking the mounting position as an installation groove as an example, a positioning hole can be opened at a certain place in the circumference of the installation groove. The positioning hole is used as an anti-mistake mark, and the positioning hole is set as a positioning design for the installation of the electric control board 8, that is, a certain position on the electric control board 8 needs to be installed corresponding to the positioning hole, thereby avoiding the direction error when the electric control board 8 is installed.

[0029] The second chamber is used to install the electronic expansion valve 3. Specifically, a second support block 13 for supporting the electronic expansion valve 3 is provided in the second chamber. The second support block 13 may be provided with multiple blocks so as to better support the electronic expansion valve 3. A clamp 14 for fixing the electronic expansion valve 3 is detachably connected to the second support block 13. The clamp 14 includes a clamping groove clamped on the outer wall of the electronic expansion valve 3 and a connecting plate connected between the clamping grooves. The connecting plate is bolted to the second support block 13. In the actual assembly process, a through hole for the electronic expansion valve 3 to extend is opened on the side wall of the second chamber of the box body 15. The electronic expansion valve 3 can be connected to an external pipeline. Before it is connected for use, in order to prevent external dust from entering the inside of the electronic expansion valve 3, a sealing sleeve 4 for sleeved on the end of the electronic expansion valve 3 is also included. When it is necessary to connect the electronic expansion valve 3 to an external pipeline, the sealing sleeve 4 can be removed. The sealing sleeve 4 can be a rubber sleeve in the prior art.

[0030] The partition plate 6 is provided with a first wire hole 9 for the connection wire between the electronic expansion valve 3 and the electronic control component to pass through. When the electronic expansion valve 3 and the electronic control component are assembled, the connection wire between the two is passed through the first wire hole 9. In order to avoid too large a gap at the first wire hole 9, a first sealing member is installed in the first wire hole 9. Specifically, the first sealing member is a sealing ring fixed in the first wire hole 9. The inner diameter of the sealing ring is smaller than the outer diameter of the connection wire, and the sealing ring is clamped on the outside of the connection wire for sealing.

[0031] A second wire passing hole 17 is provided on one side baffle plate 7 or one side side plate 10, and the second wire passing hole 17 allows the connecting wire of the electric control component to be connected to the outside world. During the actual assembly process, when the connecting wire on the electric control board 8 needs to be connected to the outside world, it can pass through the second wire passing hole 17. In order to avoid too large a gap in the second wire passing hole 17, a second sealing member is installed in the second wire passing hole 17. Specifically, the second sealing member is a sealing ring fixed in the second wire passing hole 17. The inner diameter of the sealing ring is smaller than the outer diameter of the connecting wire, and the sealing ring is clamped on the outside of the connecting wire for sealing.

[0032] Since the second wire passing hole 17 is arranged on the side of the entire control box structure, in order to prevent dust from adhering to the second seal or rainwater from washing the second seal and causing the second seal to fail, the outer wall of the side panel 10 is detachably connected with a dust cover 2 for blocking the second wire passing hole 17, and the lower end of the dust cover 2 is open. Specifically, the dust cover 2 is box-shaped and has openings on both sides, one of which is abutted against the side panel 10 for the connecting wire to pass through the second wire passing hole 17 and then enter the dust cover 2, and the other opening faces downward for the connecting wire to pass through from the bottom and connect to the outside world, and the dust cover 2 is bolted to the side panel 10.

[0033] In the second aspect, the utility model discloses an outdoor unit, specifically, the outdoor unit includes a body and a control box structure, the box body 15 of the control box structure is detachably connected to the body, specifically, the support plate 5 is bolted to the body. Of course, in the actual assembly process, the support plate 5 can also be directly welded to the body.
