[0052] Combine the following Figure 1 to Figure 7 The technical solution provided by the present invention is described in more detail.

[0053] See also Figure 1 An embodiment of the present invention provides an outdoor unit chassis, which is applicable to an outdoor unit of an air conditioner and is used to support components such as a compressor 4, an oil separator 6, and a gas-liquid separator 5.

[0054] See also Figure 1 and Figure 2 The outdoor unit chassis includes a support plate 1 and a fixing seat 2. The support plate 1 includes at least two first plates 11, and the two first plates 11 abut against each other or have a gap to form a supporting surface together. The supporting surface is used to support components inside the outdoor unit, such as a compressor 4, an oil separator 6, a gas-liquid separator 5, etc. The fixing seat 2 is located at the bottom of the first plates 11 and is fixedly connected to each first plate 11.

[0055] The support plate 1 is fixedly connected to the compressor 4, the oil separator 6, the gas-liquid separator 5 and other components. The support plate 1 adopts a structure formed by piecing together a plurality of first disc bodies 11, rather than an integral structure. In this way, on the one hand, the size of the support plate 1 can be expanded as needed. With the continuous increase in the cooling capacity of commercial air conditioners, the size of commercial air conditioners gradually increases, and accordingly, the size of the air conditioner chassis also needs to be increased. The technical solution of the present application adopts two first disc bodies 11 to piece together to form the entire support plate 1, which can greatly expand the size of the support plate 1, so that the outdoor unit chassis meets the needs of large commercial air conditioners. On the other hand, since the outdoor unit base adopts a structure formed by piecing together several parts, the processing difficulty of the outdoor unit base is also greatly reduced. The outdoor unit base includes two major parts, the support plate 1 and the fixing seat 2, and the support plate 1 includes two first disc bodies 11. The structures of the two first disc bodies 11 are the same, so a modular production method can be adopted to further reduce the processing difficulty of the first disc body 11. In addition, there is no connection relationship between the two first disc bodies 11, but they are connected to the fixing seat 2 after alignment. This structure further reduces the assembly difficulty of the outdoor unit base.

[0056] See also Figures 2 to 3b Each first disk body 11 includes a first main body 111 and a first blocking portion 112 .

[0057] See also Figures 2 to 3b , the first main body 111 has a first bearing portion 111a and a first inner recess 111b, and the first inner recess 111b is recessed relative to the first bearing portion 111a toward the direction of the fixed seat 2. The first bearing portion 111a and the first inner recess 111b are a whole, and can be formed in one piece by extrusion. The entire first main body 111 is a whole, and is also the main component for subsequently bearing the compressor 4, the oil separator 6, and the gas-liquid separator 5. In some embodiments, the number of the first inner recess 111b of each first disk body 11 is multiple, and each first inner recess 111b is arranged at intervals from each other. The shape of the first inner recess 111b is, for example, Z-shaped, Y-shaped, L-shaped or other shapes. Each first disk body 11 may include multiple first inner recesses 111b of different shapes. The first inner recess 111b is divided into two categories: a first inner recess 111b with a closed contour and a first inner recess 111b with a non-closed contour. The first inner recess 111b with a closed contour does not extend to the first notch area 111c. The first inner recess 111b extending to the first notch area 111c is open. The open first inner recess 111b and the open first inner recess 111b of another first plate 11 are combined to form a closed contour flow channel, so that the condensed water will not be blocked when discharged, and the flow process is smoother. In addition, the open first inner recess 111b and the open first inner recess 111b of another first plate 11 form a larger flow channel area, which can better meet the discharge requirements of a larger amount of condensed water.

[0058] See also Figures 2 to 3b The first blocking portion 112 is installed on a part of the edge of the first main body 111. The first blocking portion 112 protrudes relative to the first main body 111 in a direction away from the fixing seat 2 to prevent water on the first main body 111 from flowing out of the outdoor unit chassis from the edge. The remaining edge of the first main body 111 serves as a first notch area 111c, and the first notch area 111c is constructed to be open. The two first trays 11 are arranged in the following manner: the first notch areas 111c of the two first trays 11 face each other and are aligned, so that the multiple chassis can be smoothly transitioned after being symmetrically spliced, making the support surface more stable. In some embodiments, there are one or more first recessed portions 111b extending to the first notch area 111c, so that the first recessed portions 111b of the two first disk bodies 11 corresponding to the first notch area 111c can be pieced together to facilitate the drainage of the components supported by the area, so that the flow path of the condensed water is unobstructed and has a large flow area, the condensed water flows more smoothly, and the drainage effect is better; and the above-mentioned technical effect is also achieved when multiple first disk bodies 11 are spliced, which further illustrates the technical solution of the embodiment of the present invention, which not only realizes the processing and manufacturing of a larger size outdoor unit chassis and the load-bearing performance, but also optimizes the drainage performance of the outdoor unit chassis.

[0059] See also Figures 2 to 3b The first body 111 is in a rectangular shape, the first body 111 and the first blocking portion 112 are integrated, and the first blocking portion 112 is a bent edge of the edge of the first body 111. This structure can block the water accumulation on the surface of the support plate 1 on the one hand, and on the other hand, it also strengthens the strength of the support plate 1, making the support plate 1 more capable of carrying heavy loads.

[0060] In some embodiments, at least one first inner recess 111b is configured as a stepped recess, such as Figure 3b As shown. The side wall of the first inner recess 111b is in a stepped transition to the bottom surface of the first inner recess 111b, which does not affect the bearing capacity of the support plate 1. In some embodiments, a mounting hole is provided at the bottom of the first inner recess 111b, in which a bolt is installed, and the first body 111 and the fixing seat 2 are fixed together by the bolt. The total depth of the first inner recess 111b is greater than the height of the bolt head, so that after the bolt is installed, it will not protrude from the surface of the first bearing portion 111a, so that the surface of the outdoor unit chassis remains flat, which is convenient for installing components such as the compressor 4, the oil separator 6, and the gas-liquid separator 5.

[0061] In other embodiments, at least one first inner recess 111b is configured with a sidewall having an inclined surface to achieve a gradual depression. This method prevents the bearing capacity of the first body 111 from being excessively reduced due to the provision of the first inner recess 111b.

[0062] In other embodiments, the first plate body 11 itself is also constructed to be stepped and concave from the edge to the middle. The first plate body 11 with this structure can better ensure a smooth transition after multiple first plate bodies 11 are spliced ​​together, and also makes the supporting surface of the first plate body 11 more in line with the supporting requirements of the supported component, thereby achieving stable support.

[0063] See also Figure 3a and Figure 3b In some embodiments, the first bearing portion 111 a is provided with a drainage hole 113 . The drainage hole 113 penetrates through the first body 111 .

[0064] And / or, at least one of the first recessed portions 111 b is provided with a drainage hole 113 . The drainage hole 113 penetrates through the first body 111 .

[0065] The drainage hole 113 provided on the first bearing portion 111a penetrates the first bearing portion 111a and is directly connected to the bottom of the first bearing portion 111a, that is, the area where the fixing seat 2 is located. The drainage hole 113 provided on the first bearing portion 111a allows the accumulated water on the surface of the first bearing portion 111a to be directly discharged to the bottom of the first body 111 without flowing into the first inner recess 111b. In some embodiments, the surface area of ​​the first bearing portion 111a is relatively large, and the first bearing portion 111a is dispersedly provided with a plurality of drainage holes 113.

[0066] The first inner recess 111b is located at a relatively low position, and most of the condensed water on the first body 111 will flow to the first inner recess 111b under its own gravity. The drainage holes 113 provided in the first inner recess 111b allow the condensed water collected in the first inner recess 111b to be drained to the bottom of the first body 111. Since there can be multiple first inner recesses 111b, and each first inner recess 111b is separated from each other and does not penetrate, each first inner recess 111b can be provided with one or more drainage holes 113 separately.

[0067] Continue to see Figure 2 and Figure 3a , relative to the center line L1 in the width direction of the outdoor unit chassis, a plurality of first recessed portions 111b are symmetrically distributed on the edge of each first plate body 11. The first recessed portions 111b on the edge of the first plate body 11 on the same side of the center line L1 in the width direction of the outdoor unit chassis are arranged in sequence, and the structures of these first recessed portions 111b are the same.

[0068] Continue to see Figure 2 and Figure 3a , the ratio of the distance M1 between two adjacent first recessed parts 111b at the edge of the first disk body 11 on the same side of the center line L1 in the width direction of the outdoor unit chassis to the length M2 of any one of the two first recessed parts 111b is 0.8 to 1.5. Specifically, the size and structure of each first recessed part 111b at the edge of the first disk body 11 are the same. With the above-mentioned size, the outdoor unit chassis can effectively support and fix the condenser 3, so that the condenser 3 is not easily detached and damaged during transportation, which improves the reliability of the transportation of the condenser 3, and the drainage capacity is very good, so that there is no water accumulation and ice under the condenser 3.

[0069] Continue to see Figure 2 and Figure 3a , the width dimension W of the first inner recess 111b located at the edge of the first plate 11 is greater than 50 mm. The first inner recess 111b at the edge of the first plate 11 adopts the above dimensions, so that the outdoor unit chassis can effectively support and fix the condenser 3, so that the condenser 3 is not easily detached and damaged during transportation, which improves the reliability of the transportation of the condenser 3, and the drainage capacity is very good, so that there is no water accumulation and ice under the condenser 3.

[0070] See also Figure 5a and Figure 5b The first inner recesses 111b located at the edge of the first plate 11 are correspondingly installed with the condenser 3, and the convex parts between the first inner recesses 111b are the first bearing parts 111a, which play the role of installing and fixing the condenser 3. These first inner recesses 111b located at the edge of the first plate 11 are arranged intermittently, that is, they are not interconnected. This arrangement can discharge the condensed water generated by the condenser 3 in a targeted manner; secondly, when the condenser 3 has condensed water, the accumulated water can be discharged through the first inner recesses 111b in other places, or through the drainage holes 113 provided in the first bearing parts 111a, or through these first inner recesses 111b located below the condenser 3.

[0071] See also Figures 3a to 4 In some embodiments, the fixing base 2 includes a support beam 21 and a reinforcement beam 22. At least two support beams 21 are arranged in parallel. The reinforcement beam 22 is arranged between two adjacent support beams 21 and is fixedly connected to each support beam 21. The first plate 11 is fixedly connected to at least one of the support beam 21 and the reinforcement beam 22. The fixing base 2 adopts a beam structure, has good load-bearing capacity, and is light in weight.

[0072] See also Figure 6a and Figure 6bIn other embodiments, the fixing base 2 includes a box body 23, and the box body 23 is detachably connected to the first plate body 11. The fixing base 2 adopts a box-shaped structure, has a strong bearing capacity, and is light in weight. The interior of the box body 23 is connected to the drainage hole 113, and the condensed water on the upper end of the support plate 1 can be discharged into the box body 23 for storage, and then discharged to the designated area through the box body 23.

[0073] See also Figure 7 In other embodiments, the support plate 1 further includes a second plate body 12, and the second plate body 12 is arranged between two adjacent first plate bodies 11, and the second plate body 12 and the first plate bodies 11 located on both sides are assembled together to form a support surface. The number of second plate bodies 12 can be one or more. Each second plate body 12 has the same structure, so the second plate bodies 12 can be processed in a modular manner and then assembled together. If the number of second plate bodies 12 is multiple, the second plate bodies 12 do not need to be fixedly connected to each other, but are all fixedly connected to the fixing seat 2. Two adjacent second plate bodies 12 can be assembled and aligned.

[0074] Continue to see Figure 7 In some embodiments, the second tray body 12 includes a second main body 121 and a second blocking portion 122. The second main body 121 has a second bearing portion 121a and a second inner recess 121b, and the second inner recess 121b is recessed relative to the second bearing portion 121a toward the fixing seat 2. The second blocking portion 122 is installed on a part of the edge of the second main body 121, and the second blocking portion 122 protrudes relative to the second main body 121 in a direction away from the fixing seat 2; the remaining edge of the second main body 121 is divided into two second notch areas 121c spaced apart from each other, and each second notch area 121c is configured to be open; each second notch area 121c is aligned with a first notch area 111c of the first tray body 11.

[0075] The structure of the second plate 12 corresponds to the structure of the first plate 11. If the first plate 11 is in a rectangular shape, the second plate 12 is also roughly in a rectangular shape. By increasing or decreasing the number of the second plates 12, the length of the outdoor unit chassis can be changed.

[0076] As described above, the first inner recess 111b of the first plate body 11 extending to the first notch area 111c is open. The second inner recess 121b of the second plate body 12 extending to the second notch area 121c is also open. The open first inner recess 111b of the first plate body 11 and the open second inner recess 121b of the second body 121 are combined to form a closed contour flow channel.

[0077] Continue to see Figure 7In some embodiments, each second disk body 12 is symmetrical with respect to the midline L2 in the longitudinal direction of the second disk body 12. A second inner recess 121b is provided at the edge in the longitudinal direction of each second disk body 12, that is, a second inner recess 121b is provided at each second notch area 121c. The second inner recesses 121b at the edges in the longitudinal direction of two adjacent second disk bodies 12 can be spliced ​​and connected. The second inner recess 121b of each second disk body 12 can also be spliced ​​and connected with the first inner recess 111b at the edge in the longitudinal direction of the first disk body 11 (that is, the first inner recess 111b at the first notch area 111c).

[0078] The second disk 12 is arranged in the following manner: In some embodiments, there are multiple second disks 12, each of which is arranged side by side, with two first disks 11 and both sides of all the second disks 12. Looking along the length direction of the outdoor unit chassis, the first disk 11 is located at both ends, and the second disk 12 is located in the middle. By increasing or decreasing the number of second disks 12, the length of the outdoor unit chassis can be changed to meet the needs of air conditioners with different cooling capacities.

[0079] Back to Figure 1 An embodiment of the present invention further provides an outdoor unit, comprising the outdoor unit chassis provided by any technical solution of the present invention.

[0080] In some embodiments, the outdoor unit further includes a compressor 4, a condenser 3, a gas-liquid separator 5 and an oil separator 6. The compressor 4, the condenser 3, the gas-liquid separator 5 and the oil separator 6 are all supported by the support plate 1. A first inner recess 111b is provided directly below at least one of the compressor 4, the condenser 3, the gas-liquid separator 5 and the oil separator 6. Optionally, a first inner recess 111b is provided directly below the compressor 4, the condenser 3, the gas-liquid separator 5 and the oil separator 6. The mounting feet of each of the compressor 4, the condenser 3, the gas-liquid separator 5 and the oil separator 6 cross at least one first inner recess 111b.

[0081] The first inner recess 111b below the compressor 4, condenser 3, gas-liquid separator 5, and oil separator 6 respectively serves to discharge the condensed water generated by the corresponding condenser 3, gas-liquid separator 5, and oil separator 6 in a targeted manner. Specifically, the first inner recess 111b below the compressor 4 can discharge the condensed water generated by the compressor 4. The first inner recess 111b below the condenser 3 can discharge the condensed water generated by the condenser 3. The first inner recess 111b below the gas-liquid separator 5 can discharge the condensed water generated by the gas-liquid separator 5. The first inner recess 111b below the oil separator 6 can discharge the condensed water generated by the oil separator 6.

[0082] Take the example that the support plate 1 of the outdoor unit chassis includes two first plates 11 but does not include the second plate 12. The condenser 3 is roughly annular, and the condenser 3 is arranged at the edge of the support plate 1 and is jointly supported by the two first plates 11. Most of the compressor 4 is located on one of the first plates 11, and a small part is located on the other first plate 11. Therefore, the compressor 4 is mainly supported by one of the first plates 11, and the other first plate 11 is auxiliary supported. The oil separator 6 is supported by one of the first plates 11. The gas-liquid separator 5 is supported by the other first plate 11. Overall, the load-bearing capacity of the two first plates 11 is roughly the same to improve the stability of the outdoor unit.

[0083] An embodiment of the present invention further provides an air conditioner, comprising an outdoor unit provided by any technical solution of the present invention.
