Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a chassis assembly for an air conditioning outdoor unit and an air conditioning outdoor unit. Background Art

[0002] At present, in the air-conditioning outdoor unit products, especially in the large-capacity shell products of the top-outlet outdoor unit, because the whole unit is relatively large, the chassis assembly, as the largest load-bearing component of the air-conditioning outdoor unit, has high requirements for its strength and production convenience. It must have sufficient strength to support and fix the compressor, gas separator, oil separator, pipe group and other system components and other components related to the outdoor unit to ensure the reliability and stability of the outdoor unit. The chassis assembly consists of a chassis and a chassis bracket. The chassis bracket and the chassis are usually fixed directly by screw assembly. The fixing strength is high and it is detachable, but it cannot be pre-fixed during installation, which affects the installation efficiency.

[0003] The related technology provides a positioning groove through the first chassis carrying the water pump module, and provides a boss portion that protrudes upward relative to the fitting portion and a fitting portion that is fitted on the bottom surface of the first chassis on the first support foot, and the boss portion can be correspondingly assembled in the positioning groove. During actual assembly, the fitting portion is arranged on the bottom surface of the first chassis, and the boss portion is correspondingly assembled in the positioning groove, so that the support foot and the first chassis can be positioned and matched, and pre-fixation is achieved, which is convenient for subsequent assembly actions and improves installation efficiency.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, the first chassis and the first supporting foot for carrying the water pump module are pre-fixed by the positioning and matching structure of the boss and the positioning groove. The second chassis is used to carry the external unit module and needs to have a drainage function. If the positioning and matching structure of the boss and the positioning groove is applied between the second chassis and the second supporting foot, it is necessary to set the drainage structure and the positioning groove on the second chassis at the same time, which increases the complexity of the production process.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0049] Combination Figure 1-7 As shown, an embodiment of the present disclosure provides a chassis assembly for an air conditioner outdoor unit, including a chassis 10 and a chassis bracket 20 .

[0050] Combination Figure 1-2 , Figure 3 and Figure 5 As shown, the chassis 10 is provided with a positioning portion 11, and the positioning portion 11 has a drainage hole 110; the chassis bracket 20 is arranged below the chassis 10 and connected to the chassis 10, and is provided with a positioning matching portion 21, and the positioning matching portion 21 has a through hole 210. The positioning portion 11 cooperates with the positioning matching portion 21 to position the chassis 10 on the chassis bracket 20; wherein, when the positioning portion 11 cooperates with the positioning matching portion 21, the drainage hole communicates with at least part of the opening of the through hole.

[0051] The chassis assembly for the air conditioner outdoor unit provided by the embodiment of the present disclosure is adopted. The positioning portion 11 of the chassis 10 is provided with a drainage hole 110, and the positioning matching portion 21 of the chassis bracket 20 is provided with a through hole 210. When the positioning portion 11 is matched with the positioning matching portion 21, the drainage hole is communicated with at least part of the opening of the through hole, so that the water (condensed water, rain and snow water, etc.) in the chassis 10 can be discharged. The positioning portion 11 and the positioning matching portion 21 have the functions of positioning and drainage at the same time, which can reduce the setting of other drainage structures and simplify the production process. At the same time, the cooperation of the positioning portion 11 and the positioning matching portion 21 can make the chassis 10 and the chassis bracket 20 pre-positioned, so that the chassis assembly is easy to assemble, and can also increase the degree of constraint between the chassis 10 and the chassis bracket 20, and improve the stability and reliability of the chassis assembly fixation.

[0052] Optionally, the chassis bracket 20 is a sheet metal part formed by die stamping.

[0053] The chassis bracket 20 is a sheet metal part formed by die stamping, which can optimize the production process and reduce the production cost.

[0054] Optionally, combined Figure 2-3 and Figure 5 As shown, the positioning portion 11 includes a first drainage hole 111, which penetrates the chassis 10 in a vertical direction, and the hole of the first drainage hole 111 extends downward to form a positioning stretching hole edge; the positioning matching portion 21 includes a first through hole 223, which penetrates the chassis bracket 20 in a vertical direction and is arranged corresponding to the first drainage hole 111; wherein, the positioning stretching hole edge of the first drainage hole 111 can extend into the first through hole 223, so that the chassis 10 is positioned on the chassis bracket 20.

[0055] The schematic diagram of the cooperation between the positioning portion 11 and the positioning cooperation portion 21 is shown in FIG. Figure 2 As shown. The first drain hole 111 is arranged correspondingly to the first through hole 223. When installing the chassis assembly, the positioning stretching hole edge of the first drain hole 111 is inserted into the hole surface of the first through hole 223 to form a reliable hole-axis fit, which can be used as a positioning and constraint surface to ensure the maximum constraint degree of the two components. The first drain hole 111 and the first through hole 223 are matched to each other to achieve pre-positioning between the chassis bracket 20 and the chassis 10, further improving the reliability and stability of the fixation and facilitating assembly.

[0056] Optionally, the first drainage hole 111 is concentrically arranged with the first through hole 223. The concentric arrangement can achieve a better hole-axis matching effect, and can also increase the corresponding communicating area between the first drainage hole 111 and the first through hole 223, thereby enhancing the drainage effect.

[0057] Optionally, the first drain hole 111 and the first through hole 223 are located below the corresponding position of the heat exchanger and are configured to drain the condensed water of the heat exchanger. The condensed water of the heat exchanger can be quickly and effectively drained through the first drain hole 111 and the first through hole 223 to avoid affecting the performance of the heat exchanger. The first through hole 223 can be a circular through hole or a through hole of other shapes.

[0058] It can be understood that the positioning portion 11 and the positioning matching portion 21 may also include other positioning matching structures such as a tongue and a socket, a protrusion and a positioning groove.

[0059] Optionally, combined Figure 5-6 As shown, the chassis 10 is provided with supporting bosses 12, which are arranged at intervals along the length direction of the chassis 10 and are configured to support the heat exchanger, and a concave platform 13 is formed between the supporting bosses 12; Figure 1-3 As shown, the chassis bracket 20 includes an upper surface 22, which is disposed toward the bottom surface of the chassis 10 and along the length direction of the chassis 10 (i.e. Figure 1 The positioning portion 11 is arranged on the supporting boss 12 and / or the concave platform 13, and the positioning matching portion 21 is arranged on the upper surface 22.

[0060] The support bosses 12 are used to fix the system components of the air conditioner outdoor unit. Concave platforms 13 are formed between the support bosses 12. Since the support bosses 12 are arranged at intervals along the length direction of the chassis 10, the concave platforms 13 are also arranged at intervals along the length direction of the chassis 10. The concave platforms 13 of the chassis 10 and the upper surface 22 of the chassis bracket 20 are directly in contact with each other, which is used for bearing and transmitting direct force and has a buffering function.

[0061] The positioning portion 11 can be arranged on the supporting boss 12 or on the concave platform 13. When the positioning portion 11 is arranged on the supporting boss 12 and the positioning matching portion 21 is arranged on the upper surface 22, the positioning portion 11 cooperates with the positioning matching portion 21, so that the upper surface 22 and the supporting boss 12 are pre-positioned, and then fixedly connected by a fixing structure such as a screw. When the positioning portion 11 is arranged on the concave platform 13 and the positioning matching portion 21 is arranged on the upper surface 22, the positioning portion 11 cooperates with the positioning matching portion 21, so that the upper surface 22 and the concave platform 13 are pre-positioned, and then fixedly connected by a fixing structure such as a screw.

[0062] The present application takes the example that the positioning portion 11 is disposed on the supporting boss 12 and the concave platform 13 , and the positioning matching portion 21 is disposed on the upper surface 22 .

[0064] The schematic diagram of the coordination between the positioning part and the positioning coordination part is as follows: Figure 2 As shown. In the case where the positioning portion 11 is provided on the supporting boss 12, and the positioning portion 11 includes the first drainage hole 111, the first drainage hole 111 is provided on the supporting boss 12. The supporting boss 12 protrudes upward relative to the concave platform 13, and the concave platform 13 conflicts with the upper surface 22, and there is a gap between the supporting boss 12 and the upper surface 22. Therefore, the hole edge of the second through hole 211 is extended upward toward the bottom surface of the chassis to form an upper convex hole edge, so that the positioning stretching hole edge of the first drainage hole 111 can extend into the upper convex hole edge of the second through hole, that is, the upper convex hole edge of the second through hole 211 can wrap the positioning stretching hole edge of the first drainage hole 111, and the chassis 10 and the chassis bracket 20 are pre-positioned for easy assembly. The height of the first drainage hole 111 located on the supporting boss 12 is higher than the first drainage hole 111 located at other positions of the chassis 10, and cooperates with the second through hole 211 forming the upper convex hole edge to have a secondary drainage effect.

[0065] The height of the second through hole 211 may be 5 mm, and the present application does not impose any fixed limitation on the specific data range of the height of the second through hole 211 .

[0066] Optionally, combined Figure 2-3 and Figure 5 As shown, the first drainage hole 111 penetrates the concave platform 13 in the vertical direction; the first through hole 223 penetrates the upper surface 22 in the vertical direction. The concave platform 13 can fit with the upper surface 22 of the chassis bracket 20, and the distance between the concave platform 13 and the upper surface 22 of the chassis bracket 20 is relatively close. Through the cooperation between the first drainage hole 111 and the first through hole 223, positioning and drainage can be achieved.

[0067] Optionally, combined Figure 2-3 and Figure 5As shown, the first drainage hole 111 penetrates the support boss 12 in the vertical direction, and the second through hole 211 penetrates the upper surface 22 in the vertical direction. The distance between the support boss 12 and the upper surface 22 of the chassis bracket 20 is relatively close, and the first drainage hole 111 and the second through hole 211 extending upward along the hole cooperate with each other to achieve positioning and drainage. Holes at different heights of the upper surface 22 can all achieve drainage function.

[0068] Optionally, combined Figure 4 As shown, the chassis bracket 20 also includes a lower surface 23, a rear surface 24, a left end surface 25 and a right end surface 26. The lower surface 23 is arranged opposite to the upper surface 22 in the vertical direction and extends along the length direction of the chassis 10; the rear surface 24 is arranged between the upper surface 22 and the lower surface 23, and extends along the length direction of the chassis 10, with the upper end connected to the lower side of the upper surface 22 and the lower end connected to the upper side of the lower surface 23; the left end surface 25 is arranged on the left side of the rear surface 24 along the length direction of the chassis 10, and the left end surface 25 is arranged on the left side of the rear surface 24. The upper side of the end surface 25 is connected to the upper surface 22, and the lower side of the left end surface 25 is connected to the lower surface 23; the right end surface 26 is arranged on the right side of the rear surface 24 along the length direction of the chassis 10, the upper side of the right end surface 26 is connected to the upper surface 22, and the lower side of the right end surface 26 is connected to the lower surface 23; wherein, at least one edge of the upper surface 22, the lower surface 23, the rear surface 24, the left end surface 25 and the right end surface 26 is provided with an inner bent edge 27 that bends and extends toward the middle of the chassis bracket 20.

[0069] The chassis bracket 20 is composed of five continuous surfaces, namely, an upper surface 22, a rear surface 24, a lower surface 23, a left end surface 25, and a right end surface 26. The inner bending edge 27 is a connecting surface that is bent and extended toward the middle of the chassis bracket 20 to form a U-shaped edge, or a U-shaped edge. The inner bending edge 27 is provided at the edge of one or more of the upper surface 22, the lower surface 23, the rear surface 24, the left end surface 25, and the right end surface 26, so as to enhance the compressive strength of the chassis bracket 20.

[0070] This application takes the example of setting inner bending edges 27 on the five continuous surfaces of the chassis bracket 20. The overall compressive strength of the chassis bracket 20 can be improved, and the problem of easy deformation of the chassis bracket 20 after the forklift is turned around or installed can be avoided.

[0071] Optionally, combined Figure 1 and Figure 3 As shown, the upper surface 22 is further provided with a support portion 221 , which extends toward the bottom surface of the chassis 10 and contacts the bottom surface of the chassis 10 .

[0072] The support portion 221 contacts the bottom surface of the chassis 10 , so that the moment can be transmitted, and the contact area between the chassis bracket 20 and the chassis 10 is ensured, so as to improve the supporting strength of the chassis assembly.

[0073] Optionally, combined Figure 1 and Figure 3 As shown, the support portion 221 includes an upper convex blind hole 222 , and the upper surface of the upper convex blind hole 222 is in conflict with the bottom surface of the chassis 10 .

[0074] The upper convex blind hole 222 serves as the supporting portion 221 , and the contact area between the upper surface of the upper convex blind hole 222 and the bottom surface of the chassis 10 is relatively large, which can more effectively improve the supporting strength.

[0075] Optionally, the upper convex blind hole 222 is arranged corresponding to the supporting boss 12 , extends upward toward the bottom surface of the supporting boss 12 , and can abut against the bottom surface of the supporting boss 12 .

[0076] Optionally, combined Figure 3 As shown, the lower surface 23 is provided with a reinforcing rib 231 extending along the length direction of the chassis 10 and protruding upward.

[0077] The reinforcing ribs 231 of the lower surface 23 are in the form of upward convex pressed ribs, which can more effectively improve the rigidity of the lower surface 23 in the length direction, thereby improving the overall rigidity of the chassis assembly.

[0078] Optionally, combined Figure 3 As shown, the lower surface 23 is provided with mounting holes 232 for fixing to the foundation.

[0079] The base bracket is fixed to the foundation through the mounting holes 232 on the lower surface 23 to wait for the installation position. The shape and number of the mounting holes 232 are set according to the actual situation. This application takes the three long oval mounting holes 232 designed on the lower surface 23 of the chassis bracket 20 as an example. The three mounting holes 232 are fixed to the foundation to ensure the installation reliability of the whole machine. At the same time, the long oval mounting holes 232 can reduce the requirements for the opening accuracy of the mounting holes 232.

[0080] Optionally, combined Figure 4 As shown, the rear surface 24 is provided with at least one of a hanging hole 241 , an air conditioner outdoor unit connecting pipe hole 242 and a forklift hole 243 , which penetrates the rear surface 24 in a horizontal direction.

[0081] On the rear surface 24 of the chassis bracket 20, there are designed a hoisting hole 241, an air conditioner outdoor unit connecting pipe hole 242 and a forklift hole 243, which can meet the corresponding operation, installation and online debugging operations.

[0083] The lifting hole 241, the air conditioner outdoor unit connecting pipe and the forklift hole 243 are formed by front stretching to form a flange structure extending in the horizontal direction. While effectively improving the local strength, it can also increase the folding area, effectively increase the sufficient supporting surface and stress surface, and make lifting operations, connecting pipe operations and forklift operations more convenient.

[0084] The number and specific positions of the hoisting holes 241, the air conditioner external unit connection pipe holes 242, and the forklift holes 243 are set as needed. The disclosed embodiment takes the hoisting holes 241, the air conditioner external unit connection pipe holes 242, and the forklift holes 243 as an example in which the number of each is two. The hoisting holes 241, the air conditioner external unit connection pipe holes 242, and the forklift holes 243 are arranged in sequence from the outer side of the chassis bracket 20 to the middle of the chassis bracket 20, and are symmetrically arranged on both sides of the chassis bracket 20 along the length direction of the chassis 10.

[0085] Optionally, combined Figure 3 As shown, the chassis bracket 20 is also provided with an identification icon 233, which is pressed on the upper surface of the lower surface 23 and is located at the corresponding positions of the hanging hole 241, the air conditioner outdoor unit connecting pipe hole 242, and the forklift hole 243.

The use of molds to press icons as a whole is more reliable and less costly than the ordinary air conditioner outdoor unit with a separate adhesive label.

[0087] It can be understood that the hoisting hole 241 , the air conditioner outdoor unit connecting pipe hole 242 , and the forklift hole 243 can also be pressed on the outer surface of the rear surface 24 .

[0088] Optionally, combined Figure 4 As shown, the inner bending edges 27 of the left end surface 25 and the right end surface 26 are symmetrically arranged, and the inner bending edges 27 of the left end surface 25 and the right end surface 26 are provided with screw flanging holes 251 for fixing with the side panel surface of the air conditioner outdoor unit.

[0089] The left end face 25 and the right end face 26 of the chassis bracket 20 adopt symmetrical U-shaped inner bending edges 27, and screw flange holes 251 are arranged on the inner bending edges 27 to cooperate with the side panel surface of the air conditioner outdoor unit for better fixing.

Screws pass through the first mounting hole 14 and the second mounting hole 28 to fasten the chassis 10 and the chassis bracket 20. The number of the first mounting holes 14 and the second mounting holes 28 is multiple, and the multiple first mounting holes 14 and the second mounting holes 28 are distributed along the length direction of the chassis 10 and are arranged in a non-collinear triangle.

[0091] The bottom surface of the chassis 10 is provided with a first mounting hole 14 for fixing screws at the position where it cooperates with the chassis bracket 20. The hole position of the first mounting hole 14 and the second mounting hole 28 on the chassis bracket 20 are correspondingly arranged, so that the chassis 10 and the chassis bracket 20 can be fastened by screws.

[0092] In the embodiment of the present disclosure, the chassis bracket 20 and the chassis 10 are fixed by screws on both sides along the width direction of the chassis 10, and the screws are arranged in a triangular fixing manner with front and back staggered. "△" type fixing manner (i.e., a triangular non-collinear fixing manner, such as Figure 6 The "one" type fixing method (indicated by the dotted lines at A and B in the middle) is more secure and reliable than the "one" type fixing method (i.e., the co-linear fixing method), and increases the contact surface and force arm of the screw fixing, ensuring a larger base surface and a larger fixing force arm. For the vibration and transportation strength tests of the chassis assembly, it can effectively avoid the generation of rotational torque during the vibration transportation of the whole machine, resulting in the problem of poor stability of the chassis assembly, deformation and displacement of the chassis bracket 20 and the chassis 10. Furthermore, it can effectively avoid the problem of large vibration impact of the air-conditioning system components and the connected components such as the pipe group causing damage to the pipeline, causing the pipeline to rupture and the air-conditioning outdoor unit to be unusable due to poor stability. Through the effective fixed connection of non-co-linear screws, a high-strength chassis assembly design is achieved, which can effectively ensure the reliability of the air-conditioning outdoor unit and reduce the failure rate and maintenance costs.

[0093] Optionally, the second mounting hole 28 is provided on the upper surface 22 of the chassis bracket 20 , and the second mounting hole 28 is a flanged hole, which can limit the first mounting hole 14 and facilitate screw tightening.

[0094] Optionally, combined Figure 1 and Figure 5-6As shown, the chassis 10 includes a plurality of sub-chassis 15, each of which is provided with vertical sides 16 on all sides, and the vertical sides 16 include a left vertical side 161 and a right vertical side 163. The left vertical side 161 is provided on the left side of the sub-chassis 15 along the length direction of the chassis 10 and extends upward, and is provided with a first fixing hole 162; the right vertical side 163 is provided on the right side of the sub-chassis 15 along the length direction of the chassis 10 and extends upward, and is provided with a second fixing hole 164; wherein, the left vertical side 161 and the right vertical side 163 are symmetrically arranged, and when the plurality of sub-chassis 15 are connected along the length direction of the chassis 10, the left vertical sides 161 and the right vertical sides 163 of two adjacent sub-chassis 15 fit together, and the first fixing hole 162 corresponds to the second fixing hole 164.

[0095] The chassis 10 is configured as a split chassis 10 including a plurality of sub-chassis 15. The sub-chassis 15 has a small single component volume, low mold cost, convenient production, low cost, and high component versatility. The number of sub-chassis 15 is determined according to the ratio of the length of the sub-chassis 15 to the total length of the whole machine. The embodiment of the present disclosure takes the single consumption of the chassis bracket 20 and the sub-chassis 15 as an example. The fastening direction of two adjacent sub-chassis is as follows: Figure 6 The length of the sub-chassis 15 is equal to half of the total length of the whole machine. The chassis 10 adopts a 1+1 combination type. The sub-chassis 15 can be combined into a chassis after rotating 180 degrees. The chassis has a high commonality rate of parts and few non-common parts. It is effectively fixed by screws to form a chassis.

[0096] The disclosed embodiment provides a chassis assembly for an air conditioner outdoor unit with low development cost, easy production and operation, and high stability. The chassis 10 is disassembled into a completely universal combined sub-chassis 15, which reduces the number of components, simplifies the assembly production process, reduces mold development costs and component production costs, and improves component versatility and reduces assembly production complexity. This reduces the overall development cost and is more convenient for turnover and transportation.

[0097] Combination Figure 5 and Figure 7 As shown, vertical edges 16 are arranged around the sub-chassis 15. The chassis 10 is formed by integral stretching of a mold, and the cross section is a U-shaped structure, which can ensure the strength after overall stretching and the continuity of the adjacent vertical edges 16 around the circumference, and ensure that the water collected in the air conditioner outdoor unit is discharged from the drainage holes at a corresponding height lower than the vertical edges 16.

[0098] The left vertical side 161 and the right vertical side 163 of the sub-chassis 15 are symmetrically arranged, so that after the sub-chassis 15 is rotated 180°, when multiple sub-chassis 15 are connected along the length direction of the chassis 10, the left vertical sides 161 and the right vertical sides 163 of two adjacent sub-chassis 15 fit together. At the same time, the left vertical side 161 is provided with a first fixing hole 162, and the right vertical side 163 is provided with a second fixing hole 164. The first fixing hole 162 and the second fixing hole 164 are arranged correspondingly, and screws are used to pass through the first fixing hole 162 and the second fixing hole 164 to fix the two adjacent sub-chassis 15 in connection, so as to ensure the reliability of the fixation between the two. Figure 6 As shown, the vertical sides 16 of two adjacent sub-chassis 15 are fixed together to form a double vertical side 16 surface matching mode, at this time, the strength of the middle vertical side 16 is increased exponentially, and the supporting strength of the chassis 10 along the width direction is enhanced. The strength of this structural design can replace the reinforced iron parts at the bottom of the chassis 10 of the ordinary air conditioner outdoor unit, and sufficient strength can be provided without using reinforced iron parts.

[0099] Optionally, combined Figure 5 As shown, the chassis 10 is provided with a mounting boss 17, and the mounting boss 17 includes a first boss 171 and a second boss 172, wherein the first boss 171 extends along the width direction of the chassis 10; the second boss 172 extends along the width direction of the chassis 10 and is connected to the first boss 171; wherein, the height of the mounting boss 17 is higher than the heights of all other planes in the chassis 10, and the upper surface of the mounting boss 17 is provided with a fixing hole 173 for fixing the system components of the air conditioner outdoor unit.

[0100] The first boss 171 and the second boss 172 form a front-to-back continuous mounting boss 17. The front-to-back continuous boss profiling design can improve the overall strength of the chassis 10. The mounting boss 17 is provided with a fixing hole 173 for the system components, which is used to fix the corresponding system components (such as a compressor, gas separator, oil separator, etc.). The mounting boss 17 is the highest plane inside the chassis 10, which effectively prevents the screws fixing the system components or the system components from being immersed in water, causing rust and other problems.

[0101] Optionally, combined Figure 5 As shown, the chassis 10 is further provided with an inner concave surface 18 , the height of the inner concave surface 18 is lower than the heights of all other planes in the chassis 10 , and the inner concave surface 18 is provided with a second drainage hole 181 .

[0104] The air-conditioning outdoor unit provided in the embodiment of the present disclosure includes the chassis assembly for the air-conditioning outdoor unit described in any of the above embodiments, and therefore has all the beneficial effects of the chassis assembly for the air-conditioning outdoor unit described in any of the above embodiments, which will not be repeated here.

[0105] Optionally, two chassis brackets 20 are respectively arranged on both sides of the chassis 10 in the width direction, and the support boss 12 is arranged below the heat exchanger. The chassis assembly can effectively support the air conditioner outdoor unit with high strength. At the same time, the condensed water of the heat exchanger can also be quickly and effectively discharged through the first drainage hole 111 provided on the chassis 10 and the first through hole 223 of the chassis bracket 20, so as to avoid affecting the performance of the heat exchanger.
