Detailed Implementation

[0026] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0027] This embodiment provides an air conditioner outdoor unit chassis 100, such as Figures 1 to 5 As shown, the compressor pump mounting points of the chassis 100 are provided with annular ribs 210, and with the center of the area enclosed by the three pump mounting points as the center, the chassis 100 is provided with a central frustum 300 and an inner annular rib 400 and an outer annular rib 500 arranged around the central frustum 300. The inner annular rib 400 is located inside the pump mounting points, and the outer annular rib 500 is located outside the pump mounting points.

[0028] The air conditioner outdoor unit chassis 100 provided in this embodiment has an annular rib 200 at the compressor pump foot bolt mounting location, which improves the structural strength of the pump foot bolt mounting location and the annular rib 200 also limits the position of the pump foot bolt. The chassis 100 also has a central frustum 300 in the center of the area enclosed by the pump foot bolt, and annular ribs are provided on both the inner and outer sides of the pump foot bolt, which improves the structural strength of the center of the area enclosed by the pump foot bolt and the inner and outer sides of the pump foot bolt, thereby greatly improving the structural strength of the chassis where the compressor is mounted and reducing the deformation of the outdoor unit when it is dropped.

[0029] Specifically, in this embodiment, the annular rib 200, the central frustum 300, the inner annular rib 400, and the outer annular rib 500 are all of equal height. This equal height structure allows for better support of components such as the compressor. Furthermore, the height h of the annular rib 200 and the other two ribs is 13mm to 15mm, for example, 14mm; the draft angle α is 20° to 30°, for example, 30°; and each bend has a 2mm to 5mm rounded corner transition to reduce stress.

[0030] Specifically, in this embodiment, the annular rib 200 is connected to both the inner annular rib 400 and the outer annular rib 500. This arrangement allows both the inner annular rib 400 and the outer annular rib 500 to more directly support the annular rib 200, thereby reducing the deformation of the chassis 100, reducing the tilt of the pump foot bolts, and better supporting the pump body.

[0031] Specifically, in this embodiment, the width of the annular rib 200 is 4mm to 5mm, for example, it can be 4.5mm.

[0032] Specifically, in this embodiment, as Figure 1 and Figure 2 As shown, the chassis 100 is provided with a drain outlet 111, and the bottom 110 of the chassis 100 is sloped from high to low from the periphery towards the drain outlet 111. This design allows condensate falling on the chassis 100 to be drained more promptly, thereby preventing water accumulation on the chassis 100.

[0033] Specifically, in this embodiment, as Figure 1 As shown, the inner ring ribs 400 between two adjacent ring ribs 200 are provided with a first drainage channel 610; along the sloping direction from high to low along the bottom 110 of the chassis 100, the outer ring ribs 500 between the lowest ring rib 200 and the other two ring ribs 200 are all provided with a second drainage channel 620. With this arrangement, water between the central truncated cone 300 and the inner ring ribs 400 can be drained outward through the first drainage channel 610. Water between the inner ring ribs 400 and the outer ring ribs 500 can be drained outward through the second drainage channel 620. Of course, due to the inclination of the chassis bottom 110 of the chassis 100, the water between the rib segment of the outer ring rib 500 at a higher position and the corresponding rib segment of the inner ring rib 400 will first flow through a higher first drainage channel 610 to the space between the inner ring rib 400 and the central truncated cone 300, and then be discharged to the outside of the outer ring rib 500 through another lower first drainage channel 610 and its corresponding second drainage channel 620, and finally discharged through the drain outlet 111.

[0034] Specifically, in this embodiment, along the inclined direction from high to low along the bottom 110 of the chassis 100, the annular rib 200 at the lowest position and one of the other two annular ribs 200 are both provided with connecting ribs 250 between themselves and the central truncated cone 300, and the connecting rib 250 extends along the line connecting the center of the corresponding annular rib 200 and the center of the central truncated cone 300; a third drainage channel 630 is provided between the other of the other two annular ribs 200 and the central truncated cone 300. The connecting rib 250 serves to connect and structurally strengthen the corresponding annular rib 200 and the central truncated cone 300. The reason why the two annular ribs 200 located at higher positions are not both connected to the central truncated cone 300 is to leave a third drainage channel 630. This allows water between the rib segment of the outer annular rib 500 at the higher position and the corresponding rib segment of the inner annular rib 400 to first flow through the higher first drainage channel 610 to the space between the inner annular rib 400 and the central truncated cone 300, and then through the third drainage channel 630 to another lower first drainage channel 610. The water is then discharged outside the outer annular rib 500 through the lower first drainage channel 610 and its corresponding second drainage channel 620.

[0035] Specifically, in this embodiment, the outer circular rib 500 is provided with reinforcing ribs 510 extending radially outward, and the reinforcing ribs 510 are at the same height as the outer ring rib. That is, in this embodiment, as shown... Figure 5 As shown, the annular rib 200, the central truncated cone 300, the inner annular rib 400, the outer annular rib 500, and the reinforcing rib 510 are of equal height. Among them, the reinforcing rib 510 provides support and reinforcement for the outer annular rib 500.

[0036] Specifically, in this embodiment, as Figure 1 and Figure 2 As shown, a front corner boss 710 is provided in the front corner area. The front corner boss 710 is connected to the adjacent chassis flange and to the outer circular rib 500. This arrangement can improve the structural strength of the front corner area and provide support and reinforcement for the outer circular rib 500.

[0037] In this embodiment, a rear corner boss 720 is provided in the rear corner region of the chassis 100. The rear corner boss 720 is connected to the outer circular rib 500, and a drainage groove 800 is provided between it and the adjacent chassis flange. This arrangement can firstly improve the structural strength of the rear corner region to a certain extent, and also provide support and reinforcement for the outer circular rib 500; secondly, the drainage groove 800 facilitates drainage.

[0038] In this embodiment, in addition to the front corner boss 710 and the rear corner boss 720, a reinforcing boss 730 can also be provided on the outer side of the outer ring rib 500 along the circumference. The three are arranged at intervals along the circumference of the outer ring rib 500 to jointly support the outer ring rib 500.

[0039] Specifically, in this embodiment, the reinforcing rib 510 is higher than the front corner boss 710, and the front corner boss 710 and the rear corner boss 720 are at the same height. The front corner boss 710, the rear corner boss 720, and the reinforcing boss 730 have relatively large areas and slightly lower heights, forming a stepped reinforcing structure with the bottom plate 110 and the outer circular rib 500. The height of each boss is 8mm to 10mm, for example, 9mm; the draft angle is 20° to 30°, for example, 30°; and each bend has a rounded transition of 1.5mm to 2.5mm, for example, 2mm.

[0040] The outdoor unit chassis 100 provided in this embodiment can be obtained through topographic optimization design, such as... Figure 3 and Figure 4 As shown, the air conditioner outdoor unit chassis 100 provided in this embodiment was obtained through a random morphology optimization. Figure 3 The annular ribs 200, front corner bosses 710, and rear corner bosses 720 are shown in the diagram. After designing and refining the first optimized contour, a second morphological optimization is performed. The second morphological optimization uses annular optimization, adding a central frustum 300 at the center of the area enclosed by the three annular ribs 200, and adding circular ribs on both sides of the pump foot bolts. The central frustum 300 and the circular ribs are connected by connecting ribs 250 to improve the strength of the compressor side of the chassis 100. In addition, the optimized result after combination is redesigned, and the drainage channels (including guide channels and guide grooves 800) of the chassis 100 are laid out to obtain the final combined ribs. This structure improves the strength and rigidity of the compressor side, thereby avoiding severe deformation under drop conditions. Therefore, compared with the existing chassis, the chassis 100 provided in this embodiment can be appropriately thinned while maintaining comparable strength, thus reducing material costs.

[0041] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
