[0003] However, the bottom disc of the air conditioner outdoor unit in the prior art has insufficient strength, and when it falls during transportation, the deformation of the bottom disc is obvious, which causes the internal unit to be damaged. UTILITY MODEL CONTENTS

[0004] The first object of the utility model is to provide a bottom disc to solve the technical problem of obvious deformation when the bottom disc falls in the prior art.

[0005] The bottom disc provided by the utility model is applied to an air conditioner outdoor unit, and the bottom disc comprises a disc bottom and a disc edge which are fixedly arranged, a plurality of circular tables are protruded upward from the disc bottom, the top surface of the circular table is concave downward and provided with a sunken table coaxial with the circular table, so that the top surface of the circular table is annular and the width range is 2-6mm, and the bottom surface of the sunken table is higher than the disc bottom, and each sunken table is used for embedding one pump foot of the compressor.

[0006] The bottom disc provided by the utility model can have the following beneficial effects:

[0007] The disc bottom of the bottom disc is provided with a plurality of circular tables which are concave downward and provided with sunken tables, and the circular tables and the sunken tables form a stepped structure on the bottom disc, which can improve the structural strength of the area of the disc bottom for mounting the compressor, thereby improving the supporting strength and the carrying capacity of the compressor mounting area on the bottom disc, effectively avoiding the deformation of the bottom disc after being subjected to the weight of the compressor, and effectively resisting external destructive force, thereby effectively avoiding the obvious deformation of the bottom disc when falling or the like. In addition, the stepped structure formed by the circular tables and the sunken tables on the bottom disc can also have the effect of buffering and damping, thereby weakening the damage when subjected to external destructive force, and effectively avoiding the vibration generated by the operation of the compressor from being transmitted outward, thereby improving the product performance.

[0008] Compared with the multi-rib convex table, in the utility model, the circular table bears the compressor, the circular table occupies a small space, which is conducive to reducing the material and reducing the cost, and the structural strength of the circular table along the circumferential direction is more uniform, the buffering and damping effect is more uniform, and the carrying capacity along the axial direction is higher, thereby being conducive to the stability of the compressor.

[0009] Further, along the circumferential direction of the circular platform, the side surface of the circular platform is connected with a plurality of reinforcing bosses, the reinforcing bosses are upwardly protruded from the bottom disc, the top surface of the reinforcing bosses is lower than the top surface of the circular platform, and the reinforcing bosses extend along the radial direction of the corresponding circular platform.

[0010] The reinforcing bosses include inclined reinforcing bosses, the extending direction of the inclined reinforcing bosses is not parallel to the length direction and the width direction of the bottom disc, and / or the reinforcing bosses include parallel reinforcing bosses, the extending direction of the parallel reinforcing bosses is parallel to the length direction or the width direction of the bottom disc.

[0011] In the technical scheme, the reinforcing bosses can support the circular platform from the periphery of the circular platform, and the reinforcing bosses are arranged along the radial direction of the corresponding circular platform, so as to further improve the structural strength and the bearing capacity of the circular platform, wherein the inclined reinforcing bosses can simultaneously strengthen the strength of the nearby region along the length direction and the width direction of the bottom disc, so as to have better supporting and structural strengthening effects.

[0012] Further, at least part of the side surfaces of the adjacent reinforcing bosses are provided with connecting bosses, the connecting bosses are upwardly protruded from the bottom disc, the top surface of the connecting bosses is lower than the top surface of the reinforcing bosses, and the top surface of the connecting bosses is also connected with the side surface of the corresponding circular platform.

[0013] In the technical scheme, the three types of bosses, i.e. the circular platforms, the reinforcing bosses and the connecting bosses, form a multi-stage stepped structure, so as to further improve the structural strength of the bottom disc, the buffer and vibration resistance capacity, and the ability to resist external damage.

[0014] Further, the number of the circular platforms is three, and the three circular platforms are arranged in a triangular shape.

[0015] The side surface of each circular platform is connected with at least four reinforcing bosses, and each circular platform is connected with a reinforcing boss extending towards the space between the other two circular platforms.

[0016] In the technical scheme, the stability of the triangular structure enables the three circular platforms to provide stable support for the compressor as a whole, and the arrangement of one reinforcing boss extending towards the space between the other two circular platforms for each circular platform can ensure the structural strength of the middle region of the three circular platforms, so that the region can effectively support the compressor without deformation after the compressor is installed.

[0017] Further, along the direction from bottom to top, the side surface of the sunken platform is outwardly inclined and forms an included angle of 15°-25° with the bottom surface thereof.

[0018] And / or, the side surface of the reinforcing boss forms an included angle of 55°-65° with the top surface thereof.

[0019] Further, the top surface of the circular truncated cone and the side surface of the sunken platform are connected by a first round corner, and the radius of the first round corner is 1-3 mm.

[0020] Further, the side surface of the reinforcing boss and the top surface thereof, the side surface of the reinforcing boss and the bottom of the disc, and the reinforcing boss and the circular truncated cone are connected by a second round corner.

[0021] In the technical solution, the round corner is used to connect the adjacent surfaces, which can effectively reduce the stress concentration at the connection of the adjacent surfaces.

[0022] Further, the disc rim includes a front rim, a first side rim, a rear rim and a second side rim connected in sequence along the circumference of the disc bottom, and the compressor is arranged close to the front rim and the first side rim.

[0023] The disc rim extends upward, and among the front rim, the first side rim, the rear rim and the second side rim, at least the front rim and the first side rim are provided with a downward turned edge.

[0024] In the technical solution, the turned edge is provided, which can effectively improve the rigidity and structural strength of the disc rim, thereby effectively improving the ability of the first side rim, the front rim and the corner connecting the two to resist impact force when falling.

[0025] Further, the turned edge is arranged on the outside of the disc rim and is arranged in close contact with the disc rim.

[0026] In the technical solution, the turned edge is turned outward relative to the disc rim, so that the overall space occupied by the turned edge and the disc rim is relatively small, and the two are in close contact, and the two can jointly resist external force, have stronger ability to resist impact force and prevent deformation. In addition, compared with turning inward, turning the edge outward can reduce the fitting gap between the bottom disc and the panel and the side plate corresponding to the disc rim provided with the turned edge, so that the sealing performance of the shell is better. Turning the edge outward can also better avoid the situation that other assembly parts are scratched by the turned edge, for example, when wrapping the compressor with sound-absorbing cotton and other assembly parts, the sound-absorbing cotton and other assembly parts can be better protected from being scratched by the turned edge.

[0027] Further, the thickness of the bottom disc is 0.9-1.0 mm, and further, the thickness of the bottom disc is 0.95 mm.

[0028] In the technical solution, the thickness of the bottom disc is smaller than the 1.15 mm thickness of the bottom disc in the prior art, so the material cost can be reduced.

[0044] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0045] First of all, it needs to be pointed out that in the drawings, the arrows "a", "b" refer to the front and rear of the outdoor unit, and the arrows "c", "d" refer to the left and right sides of the outdoor unit.

[0046] Figure 1 The base pan 10' of the outdoor unit of the prior art is shown. As shown in Figure 1 , the base pan 10' is provided with three mounting holes 11' for fixing and mounting three pump feet of the compressor. However, during transportation, when falling occurs, the base pan 10' is prone to relatively obvious deformation, i.e. relatively large deformation, and causes damage to the components inside the outdoor unit housing.

[0047] In order to solve the above problems, the present embodiment provides a base pan 10, as shown in Figure 2 and Figure 3 , the base pan 10 comprises a fixedly arranged pan bottom 100 and a rim 200, the pan bottom 100 is upwardly provided with a plurality of circular platforms 110, the top surface of the circular platform 110 is downwardly concave and provided with a sunken platform 120 coaxial with the circular platform 110, so that the top surface of the circular platform 110 is annular and the width range is 2-6mm; the bottom surface of the sunken platform 120 is higher than the pan bottom 100, and each sunken platform 120 is used for embedding one of the pump feet of the compressor.

[0048] The base pan 10 provided by the present embodiment, the pan bottom 100 is upwardly provided with a plurality of circular platforms 110, and the top surface of the circular platform 110 is downwardly concave and provided with a sunken platform 120, the stepped structure formed by the circular platform 110 and the sunken platform 120 in the base pan 10 can improve the structural strength of the area of the pan bottom 100 for mounting the compressor, thereby improving the supporting strength and carrying capacity of the compressor mounting area of the base pan 10, effectively avoiding the case of sinking and deformation of the base pan 10 after being subjected to the weight applied by the compressor, and also effectively resisting external destructive force, thereby effectively avoiding the obvious deformation of the base pan 10 at the time of falling and the like. In addition, the stepped structure formed by the circular platform 110 and the sunken platform 120 in the base pan 10 can also have the effect of buffering and damping, thereby weakening the damage when subjected to external destructive force, and also effectively avoiding the transmission of vibration generated during the operation of the compressor to the outside, thereby improving the product performance.

[0049] Compared with the multi-rib boss, in the embodiment, the compressor is carried by the circular boss 110, and the circular boss 110 not only occupies a small space, but also is beneficial to reducing the material and cost, the structural strength of the circular boss 110 along the circumferential direction is more uniform, the buffering and damping effect is more uniform, and the carrying capacity along the axial direction is higher, thereby being beneficial to the stability of the compressor.

[0050] The chassis 10 provided in the embodiment is verified by CAE simulation to have higher rigidity than the prior art under the same material thickness condition, and is verified by drop experiment to have a greatly reduced drop deformation. If the rigidity is kept the same, the material thickness of the chassis 10 can be thinner, thereby reducing the cost.

[0051] Specifically, in the embodiment, as shown in Figure 2 and Figure 3 , along the circumferential direction of the circular boss 110, the side surface of the circular boss 110 is connected with a plurality of reinforcing bosses, the reinforcing bosses are upwardly protruded from the disc bottom 100, the top surface of the reinforcing bosses is lower than the top surface of the circular boss 110, and the reinforcing bosses extend along the radial direction of the corresponding circular boss 110. The reinforcing bosses can support the circular boss 110 around the circular boss 110, and the reinforcing bosses are arranged along the radial direction of the corresponding circular boss 110, thereby being beneficial to further improving the structural strength and carrying capacity of the circular boss 110. The oblique reinforcing boss 130 can simultaneously strengthen the strength of the nearby region along the length direction and the width direction of the chassis 10, and therefore has better supporting and structural strengthening effects.

[0052] Continuing as shown in Figure 2 and Figure 3 , the reinforcing bosses further include parallel reinforcing bosses 140, and the extending direction of the parallel reinforcing bosses 140 is parallel to the length direction or the width direction of the chassis 10. The parallel reinforcing bosses 140 can also improve the structural strength and carrying capacity of the compressor mounting region on the chassis 10.

[0053] Continuing as shown in Figure 2 and Figure 3 , in the embodiment, the side surfaces of part of the adjacent reinforcing bosses are provided with connecting bosses 150, the connecting bosses 150 are upwardly protruded from the disc bottom 100, the top surface of the connecting bosses 150 is lower than the top surface of the reinforcing bosses, and the top surface of the connecting bosses 150 is also connected with the side surface of the corresponding circular boss 110. In this way, the circular boss 110, the reinforcing bosses and the connecting bosses 150 form a multi-stage stepped structure, thereby further improving the structural strength, the buffering and damping capacity and the ability to resist external force damage of the chassis 10.

[0054] Specifically, in the embodiment, as shown in Figure 2 andFigure 3 As shown, the number of the circular platforms 110 is three, and the three circular platforms 110 are arranged in a triangular shape. The stability of the triangular structure enables the three circular platforms 110 to provide stable support for the compressor as a whole.

[0055] In the embodiment, the side surface of each circular platform 110 is connected with at least four reinforcing bosses, and each circular platform 110 is connected with a reinforcing boss whose extending direction is towards the space between the other two circular platforms 110, i.e. Figure 3 The three reinforcing bosses 130 are arranged along the central axis of the three circular platforms 110. Such arrangement can ensure the structural strength of the middle region of the three circular platforms 110, so that the region can effectively support the compressor without sinking and deforming after the compressor is installed.

[0056] Specifically, in the embodiment, as shown in Figure 5 In the embodiment, as shown in Figure 5 the side surface of the sink platform 120 is outwardly inclined and forms an angle of 15°-25° with the bottom surface thereof, i.e. the draft angle is in the range of 15°-25°. In this way, the draft angle is relatively large, thereby facilitating demolding. The draft angle is complementary to α in

[0057] In the embodiment, as shown in Figure 5 the angle between the side surface of the reinforcing boss and the top surface thereof is in the range of 55°-65°, i.e. Figure 5 the value of β in is in the range of 55°-65°. In this arrangement, the inclination angle of the side surface of the reinforcing boss relative to the vertical surface is relatively large, thereby the reinforcing boss has a good supporting effect and structural reinforcing effect on the circular platform 110. Specifically, β can be 60°, and β can also take any other angle value in the range of 55°-65°.

[0058] In the embodiment, as shown in Figure 5 the top surface of the circular platform 110 and the side surface of the sink platform 120, and the side surface of the sink platform 120 and the bottom surface thereof are connected and transitioned through a first round corner, and the radius of the first round corner is in the range of 1-3 mm, for example, the radius of the first round corner can be 2 mm. The first round corner can effectively reduce stress concentration.

[0059] Figure 3 w in is the width of the top surface of the circular platform 110, in combination with Figure 3 and Figure 5As shown, the width value represented by w does not include the width of the rounded corner area, that is, in this embodiment, the width of the top surface of the circular truncated cone 110 does not include the width of the rounded corner area, and in this embodiment, the width w of the top surface of the circular truncated cone 110 can be 2-6 mm, and specifically can be 3 mm. With such a value, the width of the top surface of the circular truncated cone 110 takes into account both structural strength and structural compactness, so as not to be too narrow and too small in strength, and not to be too wide and occupy too much space.

[0060] In this embodiment, the side surface of the reinforcing boss and the top surface thereof, the side surface of the reinforcing boss and the disc bottom 100, and the reinforcing boss and the circular truncated cone 110 are also connected and transitioned through rounded corners. In order to distinguish from the first rounded corner, the second rounded corner can be referred to, and of course, the radii of the second rounded corners at different positions can be different or the same, which can be determined according to the specific situation of the surface connected by the rounded corner.

[0061] Specifically, as shown in Figure 3 , Figure 6 and Figure 7 , the disc rim 200 includes a front rim 201, a first side rim 202, a rear rim 203 and a second side rim 204 connected in sequence along the circumference of the disc bottom 100, and the compressor is arranged close to the front rim 201 and the first side rim 202; the disc rim 200 is arranged extending upward, and of the front rim 201, the first side rim 202, the rear rim 203 and the second side rim 204, at least the front rim 201 and the first side rim 202 are provided with a downward flange 210. It should be noted that when the flange 210 is arranged, the valve plate should be avoided, that is, the position of the valve plate is not provided with the flange 210. The arrangement of the flange 210 can effectively improve the rigidity and structural strength of the disc rim 200, so as to effectively improve the ability of the first side rim 202, the front rim 201 and the corner connecting the two to resist impact force when falling. Of course, although in this embodiment, only part of the front rim 201 and the first side rim 202 and the part connected with the front rim 201 are provided with the flange 210, in other embodiments of the present application, other disc rims 200 parts such as the second side rim 204 or the rear rim 203 can also be provided with the flange 210 to improve the rigidity and strength.

[0062] Specifically, as shown in Figure 7As shown, the flange 210 is arranged on the outer side of the rim 200 and is arranged in abutment with the rim 200. The flange 210 is outwardly turned relative to the rim 200, and the overall space occupied by the flange 210 and the rim 200 is relatively small, and the two are in abutment, and the two can jointly resist external forces, and have stronger ability to resist impact forces and prevent deformation. In addition, compared with inward turning, outward turning of the flange 210 can reduce the fitting gap between the bottom plate 10 and the panel and the side plate corresponding to the rim 200 provided with the flange 210, that is, the fitting gap between the bottom plate 10 and the front panel and the right side plate in the embodiment, so that the sealing performance of the shell is better; the outward turning of the flange 210 can also better avoid the situation that other assembly parts are scratched by the flange 210 during assembly of other assembly parts, for example, when the compressor is wrapped with sound-absorbing cotton and other assembly parts, the sound-absorbing cotton and other assembly parts can be better protected from being scratched by the flange 210.

[0063] It should be noted that in other embodiments of the present application, the flange 210 can also be arranged on the inner side of the rim 200; of course, as long as the space allows, the rigidity and strength meet the requirements, and a certain gap between the rim 200 and the flange 210 is also allowed.

[0064] In the embodiment, the thickness of the bottom plate 10 is in the range of 0.9-1.0 mm, and further, the thickness of the bottom plate 10 can be 0.95 mm. Compared with the thickness of 1.15 mm of the bottom plate 10' in the prior art, the thickness of the bottom plate 10 provided in the embodiment is reduced by nearly 20%, so the material cost can be greatly reduced.

[0065] In the embodiment, the related structure for mounting the compressor on the bottom plate 10 is arranged on the left side of the bottom plate 10, which is suitable for an outdoor unit with the compressor placed on the left, but it should be noted that in other embodiments of the present application, the related structure for mounting the compressor on the bottom plate 10 can also be arranged on the right side of the bottom plate 10, which is suitable for an outdoor unit with the compressor placed on the right.

[0066] The embodiment also provides an air conditioner outdoor unit, which comprises the above-mentioned bottom plate 10 and further comprises a compressor, and the pump feet of the compressor are respectively embedded in one of the sink pads 120 and fixedly connected with the sink pad 120.

[0067] Specifically, as shown in the figure, Figure 2 The bottom surface of the sink pad 120 is provided with a mounting hole 11, and the bolt for fixing the pump feet passes through the mounting hole 11 and fixes the pump feet to the bottom plate 10. In addition, a support can also be arranged below the bottom plate 10 to support the bottom plate 10 and the compressor and the like thereon.

[0068] In summary, in order to reduce the obvious deformation of the chassis 10 in the falling condition during transportation and reduce the cost, the embodiment provides a chassis 10 applied to an air conditioner outdoor unit and an air conditioner outdoor unit. The chassis 10 is designed by optimizing the topography. Specifically, a circular table 110 is arranged in the region of the chassis 10 for mounting and fixing the compressor pump foot bolt, a plurality of inclined reinforcing bosses 130, parallel reinforcing bosses 140 and connecting bosses 150 are arranged on the side of the circular table 110, and a flange 210 is arranged on the disc edge 200 close to the compressor side edge and the front edge, which greatly improves the strength and rigidity of the chassis 10 and can ensure that the chassis 10 will not have obvious deformation in the falling condition during transportation. Moreover, under the premise of ensuring the strength and rigidity of the chassis 10, compared with the chassis 10' in the prior art, the thickness of the chassis 10 provided by the embodiment can be appropriately thinned. Specifically, the thickness can be thinned from 1.15 mm in the prior art to 0.95 mm. Therefore, the chassis 10 provided by the embodiment can also save material cost. That is, the chassis 10 provided by the embodiment can achieve the same strength with smaller thickness and effectively resist falling deformation. In addition, in the embodiment, the height of the chassis 10 gradually decreases from the edge thereof to the drain hole thereof, so the chassis 10 provided by the embodiment also has good water accumulation discharge capacity.
