[0042] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0043] See also Figure 1 , Figure 2 and Figure 3 The welding machine 100 provided in the embodiment of the present application includes a chassis 10, a diaphragm 20, a fan assembly 30, a protective chamber 40 and electrical components. The diaphragm 20 divides the chassis 10 into a clean chamber 11 and a contaminated chamber 12, the protective chamber 40 is arranged in the contaminated chamber 12, the electrical components are distributed in the clean chamber 11, the contaminated chamber 12 and the protective chamber 40, and the fan assembly 30 is arranged in the contaminated chamber 12. Through this arrangement, the electrical components located in the clean chamber 11 and the protective chamber 40 are protected and are not affected by the welding slag, dust, and other pollutants at the welding site sucked into the welding machine 100 when the fan assembly 30 is working, that is, some electrical components are protected and their lifespan is extended, so the overall lifespan of the welding machine 100 is extended.

[0044] Regarding the above-mentioned chassis 10 , the chassis 10 is the outer box body of the welding machine 100 , and the chassis 10 is used to accommodate electrical components and the like in the welding machine 100 .

[0045] For the above-mentioned diaphragm 20 and fan assembly 30, please refer to Figure 3 and Figure 4 The partition 20 is disposed in the chassis 10, and the partition 20 divides the chassis 10 into a clean chamber 11 and a contaminated chamber 12. The contaminated chamber 12 is provided with an air inlet 121 and an air outlet 122. The fan assembly 30 is disposed at the air inlet 121, and the fan assembly 30 is used to air cool the electrical components in the welding machine 100.

[0046] Among them, the clean chamber 11 is used for setting electrical components. In some embodiments, the clean chamber 11 is used for setting electrical components that are sensitive to pollution, such as capacitors 511, fan assembly boards 512, control boards 513, industrial frequency transformers 514, three-phase junction boxes 515, display panels 516, etc.

[0047] It can be understood that, since the contaminated chamber 12 is provided with an air inlet 121 and the fan assembly 30 is arranged at the air inlet 121, the clean chamber 11 is actually an independent area in the chassis 10. The clean chamber 11 is isolated from the fan assembly 30 by the transverse partition 20, so that the clean chamber 11 can protect the electrical components distributed therein and reduce the influence of pollutants such as welding slag, dust, and powder from the welding site that are sucked into the welding machine 100 when the fan assembly 30 is working.

[0048] Among them, the pollution chamber 12 is used for setting electrical components. In some embodiments, the pollution chamber 12 is used for setting electrical components that are insensitive to pollution and easily generate heat or generate a lot of heat, such as secondary side components 531, output inductors 532, main transformers 533, etc.

[0049] It is understandable that, since the contaminated chamber 12 is provided with an air inlet 121, and the fan assembly 30 is provided at the air inlet 121, the wind sucked in by the fan assembly 30 can directly dissipate the heat of the electrical components in the contaminated chamber 12. Figure 4 The wind sucked in by the fan assembly 30 cools the contaminated chamber 12 through the flow path W1. The heat generated by the electrical components in the contaminated chamber 12 can be quickly cooled by the fan assembly 30, which can greatly extend the service life of the electrical components in the contaminated chamber 12.

[0050] It is worth noting that, in some embodiments, the air inlet 121 and the air outlet 122 are arranged relative to each other, so that the air sucked in by the fan assembly 30 arranged at the air inlet 121 enters the pollution chamber 12 and can quickly flow out from the air outlet 122, so the heat dissipation efficiency is high.

[0051] For the above-mentioned protective chamber 40, please refer to Figure 4 and Figure 5 The protection chamber 40 is arranged in the contaminated chamber 12 , and the protection chamber 40 includes a clean side chamber 41 and an air duct 42 . The air duct 42 is connected to the air inlet 121 , and the air duct 42 is connected to the contaminated chamber 12 .

[0052] Among them, the clean side bin 41 is used for setting electrical components. In some embodiments, the clean side bin 41 is used for setting electrical components that are sensitive to pollution and easily generate heat or generate a lot of heat, such as the primary main power module 521, the rectifier bridge 522, the input EMC (Electromagnetic Compatibility) board 523, etc.

[0053] It can be understood that the clean side bin 41 is actually an independent area in the contaminated bin 12, so that the clean side bin 41 can protect the electrical components distributed in the period, and reduce the impact of pollutants such as welding slag, dust, and powder sucked into the welding machine 100 by the fan assembly 30 when the fan assembly 30 is working. In addition, since the protective bin 40 includes the clean side bin 41 and the air duct 42, that is, the clean side bin 41 is adjacent to the air duct 42, and since the air duct 42 is connected to the air inlet 121, the fan assembly 30 is set at the air inlet 121, and the fan assembly 30 can act on the air duct 42, please refer to Figure 4 or Figure 5The flow passage W2 for air cooling the air duct 42 by the wind sucked by the middle fan assembly 30 can not only dissipate heat for the electrical components arranged in the air duct 42, but also dissipate heat for the electrical components in the clean side bin 41, thereby further extending the service life of the electrical components in the clean side bin 41, and further extending the service life of the electrical components arranged in the air duct 42. More importantly, since the protection bin 40 is independent of the contaminated bin 12 and the air duct 42 is a part of the protection bin 40, the wind force in the air duct 42 is concentrated, and its heat dissipation efficiency is high.

[0054] In addition, since the wind force in the air duct 42 is concentrated and the heat dissipation efficiency is high, the electrical components are arranged in the air duct 42, which is beneficial to the heat dissipation of the welding machine 100 as a whole. In some embodiments, electrical components with large heat dissipation, such as the main transformer 533, can be arranged in the air duct 42. In some embodiments, a supporting member 80 is arranged outside the clean side bin 41, and the supporting member 80 is used to support the electrical components, such as the main transformer 533. Generally, the weight of the main transformer 533 is about 10 jin. When two main transformers 533 are used in combination, the weight can reach 20 jin, which is inconvenient to install. After the supporting member 80 is arranged, the electrical components are supported by the supporting member 80, which makes the installation convenient.

[0055] In some embodiments, the support member 80 includes a self-clinching stud.

[0056] In some embodiments, there are multiple protective chambers 40, and the multiple protective chambers 40 are distributed in the contaminated chamber 12. Since the protective chamber 40 is set independently of the contaminated chamber 12, the number of protective chambers 40 can be increased or decreased according to the actual power demand of the welding machine 100, and the number of electrical components set in the clean side chamber 41 and the air duct 42 can be increased or decreased to expand the application scenarios of the welding machine 100. In other words, in some usage scenarios, when the welding machine 100 has a high power demand, it is only necessary to increase the number of protective chambers 40 and the number of primary side main power modules 521 set in the clean side chamber 41, without the need to design the layout of the electrical components inside the chassis 10, saving time and effort.

[0057] In some embodiments, see Figure 5 , the number of the clean side bins 41 is two, and the air duct 42 is sandwiched between the two clean side bins 41. Since the air duct 42 is connected to the air inlet 121, and the fan assembly 30 is arranged at the air inlet 121, the fan assembly 30 can act on the air duct 42, and can not only dissipate heat for the electrical components arranged in the air duct 42, but also dissipate heat for the electrical components in the two clean side bins 41 on both sides of the air duct 42, thereby improving the utilization rate of the air duct 42.

[0058] In some embodiments, see Figure 5 A radiator 60 is also disposed in the air duct 42 to further improve the heat dissipation efficiency.

[0059] In some other embodiments, see Figure 5 The clean side bin 41 is provided with a mounting hole (not shown), the radiator 60 is provided in the mounting hole, the radiator 60 has a mounting surface 61, the mounting surface 61 is located in the clean side bin 41, and the mounting surface 61 is used for mounting the electrical components. That is, the radiator 60 dissipates heat from the electrical components, and the heat dissipation efficiency of the electrical components in the clean side bin 41 can be improved.

[0060] It is worth noting that the electrical components arranged in the clean side bin 41 may be the primary main power module 521, and the primary main power module 521 is arranged on the mounting surface 61. Since the primary main power module 521 is sensitive to pollution and is easy to generate heat and generates a large amount of heat, the primary main power module 521 is protected by the clean side bin 41, which can not only reduce the influence of pollutants such as welding slag, dust, and powder sucked into the welding machine 100 at the welding site when the fan assembly 30 is working, but also dissipate heat for the primary main power module 521 through the radiator 60 and the air duct 42, and its service life is long.

[0061] In some embodiments, see Figure 4 and Figure 5 The welding machine 100 further includes a support plate 70, which is vertically arranged in the chassis 10 with the transverse partition 20, and the clean side bin 41 is installed on the support plate 70. That is, the installation of the clean side bin 41 can be realized through the support plate 70, so that it is independent of the contaminated bin 12.

[0062] It can be understood that when the number of the clean side bins 41 is two, the number of the support plates 70 can also be two, and one support plate 70 is used for installing one clean side bin 41 .

[0063] It can be understood that, in some embodiments, the diaphragm 20 can also be installed on the support plate 70, so that the support plate 70 can provide support for the diaphragm 20 and improve the load-bearing capacity of the diaphragm 20.

[0064] It is worth noting that the configuration of the clean side bin 41 can be varied. For example, in some embodiments, see Figure 5The clean side bin 41 includes a first partition 411, a second partition 412, and a third partition 413 connected in pairs. The first partition 411, the second partition 412, the third partition 413, the transverse partition 20, and the chassis 10 together form a clean space, and a part of the electrical components are distributed in the clean bin 11 and the clean space. The first partition 411 and the second partition 412 can be installed on the support plate 70, and the third partition 413 can be installed on the transverse partition 20.

[0065] For the above-mentioned fan assembly 30, pollution chamber 12 and air duct 42, in some embodiments, please refer to Figure 4 The fan assembly 30 includes a fan cover 31 and a plurality of fans 32, the plurality of fans 32 are arranged in the fan cover 31, the fan cover 31 is disposed at the air inlet 121, a portion of the plurality of fans 32 corresponds to the air duct 42, and another portion of the plurality of fans 32 corresponds to the contaminated chamber 12. Since the fan assembly 30 includes the fan cover 31 and the plurality of fans 32, it is convenient to be disassembled from the chassis 10 as a whole. Since a portion of the plurality of fans 32 corresponds to the air duct 42, and another portion of the plurality of fans 32 corresponds to the contaminated chamber 12, the fan assembly 30 acts not only on the air duct 42 but also on the contaminated chamber 12, and both the air duct 42 and the contaminated chamber 12 have good heat dissipation functions.

[0066] For the above electrical components, please also refer to Figure 3 , Figure 4 and Figure 5 , the electrical components are distributed in the clean chamber 11, the clean side chamber 41, the polluted chamber 12 and the air duct 42. In some embodiments, the electrical components include components that are sensitive to pollution, which are arranged in the clean chamber 11, such as capacitors 511, fan assembly boards 512, control boards 513, power frequency transformers 514, three-phase junction boxes 515, display panels 516, etc. The electrical components include components that are sensitive to pollution and easily generate heat or generate large amounts of heat, which are arranged in the clean side chamber 41, such as primary side main power modules 521, rectifier bridges 522, input EMC boards 523, etc. The electrical components also include components that are insensitive to pollution and easily generate heat or generate large amounts of heat, which are arranged in the polluted chamber 12 and the air duct 42, such as secondary side components 531, output reactors 532, main transformers 533, etc.

[0067] In the embodiment of the present application, the welding machine 100 includes a chassis 10; a transverse partition 20, which is arranged in the chassis 10, and the transverse partition 20 divides the chassis 10 into a clean chamber 11 and a contaminated chamber 12, and the contaminated chamber 12 is provided with an air inlet 121 and an air outlet 122; a fan assembly 30, which is arranged at the air inlet 121; a protective chamber 40, which is arranged at the contaminated chamber 12, and the protective chamber 40 includes a clean side chamber 41 and an air duct 42, and the air duct 42 is connected to the air inlet 121, and the air duct 42 is connected to the contaminated chamber 12; electrical components are distributed in the clean chamber 11, the clean side chamber 41, the contaminated chamber 12 and the air duct 42. Through the above arrangement, since the fan assembly 30 is arranged in the contaminated bin 12, the clean bin 11 and the clean side bin 41 are actually arranged independently, that is, they are not connected to the air inlet 121 where the fan assembly 30 is located, so that a part of the electrical components are arranged in the clean bin 11 and the clean side bin 41 for protection, and the electrical components located in the clean bin 11 and the clean side bin 41 are not affected by the welding slag, dust, dust and other pollutants at the welding site sucked into the welding machine 100 when the fan assembly 30 is working, and the service life of at least some of the electrical components is long, and the service life of the welding machine 100 is long.

[0068] In addition, since the protective chamber 40 is also provided with an air duct 42, and the air duct 42 is connected with the air inlet 121, the fan assembly 30 located at the air inlet 121 can act on the air duct 42, which can not only dissipate heat for the electrical components arranged in the air duct 42, but also dissipate heat for the electrical components in the clean side chamber 41, thereby further extending the service life of the electrical components in the clean side chamber 41, and further extending the service life of the electrical components arranged in the air duct 42. More importantly, the wind force in the air duct 42 is concentrated, and the heat dissipation efficiency is high.

[0069] In some usage scenarios, electrical components that are sensitive to pollution can be set in the clean chamber 11, such as capacitors 511, fan assembly boards 512, control boards 513, power frequency transformers 514, three-phase junction boxes 515, display panels 516, etc. Electrical components that are sensitive to pollution and are prone to or generate large amounts of heat can be set in the clean side chamber 41, such as the primary side main power module 521, the rectifier bridge 522, the input EMC board 523, etc. Electrical components that are insensitive to pollution and are prone to or generate large amounts of heat can also be set in the polluted chamber 12 and the air duct 42, such as the secondary side components 531, the output reactor 532, the main transformer 533, etc. Through this setting, not only can the service life of the electrical components be extended, but also through the reasonable arrangement of the electrical components, the limited space in the chassis 10 can be reasonably used, and the space utilization rate in the chassis 10 can be improved.

[0070] See also Figure 4The embodiment of the present application provides a shutter 1, which is a waterproof, dustproof and ventilation solution. In the welding machine 100, the shutter 1 can be installed at the air inlet 121 of the chassis 10, or at the air outlet 122, or at the fan assembly 30, so as to effectively reduce or even prevent water or dust from entering the chassis 10, and facilitate ventilation inside and outside the chassis 10.

[0071] See also Figure 6 The shutter 1 provided in the embodiment of the present application includes a plurality of first blades 101 and a plurality of second blades 102; the plurality of first blades 101 are arranged along the gravity direction L1, and the plurality of second blades 102 are arranged along the gravity direction L1; the first blade 101 is parallel to the second blade 102; along the horizontal direction L2, the first blade 101 and the second blade 102 are arranged at intervals; along the horizontal direction L2, the end of the first blade 101 away from the second blade 102 is arranged downwardly inclined, and the end of the second blade 102 close to the first blade 101 is arranged downwardly inclined. The shutter 1 provided in the embodiment of the present application includes a plurality of first blades 101 and a plurality of second blades 102, that is, a two-layer waterproof and dustproof structure is formed, and its waterproof and dustproof effect is good compared with a single-layer structure. In addition, since the first blade 101 and the second blade 102 are arranged in parallel, the ventilation effect of the shutter 1 is not affected. That is, compared with the prior art, the shutter 1 provided in the embodiment of the present application has both enhanced waterproof and dustproof performance and ventilation effect.

[0072] Among them, the horizontal direction L2 is a direction perpendicular to the gravity direction L1, and the horizontal direction L2 is also a direction in which the first blade 101 and the second blade 102 are spaced apart, that is, the horizontal direction L2 is a direction from the first blade 101 arranged along the gravity direction L1 to the second blade 102 arranged along the gravity direction L1.

[0073] Here, the downward direction means being consistent with the gravity direction L1. The downward inclination means being inclined toward the gravity direction L1.

[0074] It is worth noting that, when the shutter 1 is disposed in the chassis 10 , the first blades 101 are disposed close to the outside of the chassis 10 , and the second blades 102 are disposed close to the inside of the chassis 10 .

[0075] For the first blade 101, see Figure 7 In some embodiments, one end of the first blade 101 close to the second blade 102 extends upward at a retaining angle 1011, and the retaining angle 1011 can further block water or dust, thereby improving the waterproof and dustproof performance of the shutter 1. Wherein, upward is relative to downward, that is, upward is away from the gravity direction L1.

[0076] In some embodiments, the installation direction L3 is defined such that the gravity direction L1 and the horizontal direction L2 are perpendicular to each other. For one first blade 101, the number of the blocking angles 1011 is two, and the two blocking angles 1011 are located at both ends of the first blade 101 along the installation direction L3, which can further improve the waterproof and dustproof performance of the blind 1. In addition, since the blocking angles 1011 are distributed at both ends of the first blade 101, that is, the blocking angles 1011 only occupy some corners, by setting the blocking angles 1011, the waterproof and dustproof performance of the blind 1 is improved while taking into account the ventilation performance of the blind 1.

[0077] It can be understood that, since the shutter 1 includes a plurality of first blades 101 , each first blade 101 corresponds to two blocking angles 1011 , and the number of blocking angles 1011 is actually twice the number of the first blades 101 .

[0078] In addition, it is worth mentioning that by setting the retaining angle 1011, when the first blade 101 is installed with external equipment such as the welding machine 100, auxiliary installation can be performed through the retaining angle 1011, for example, the retaining angle 1011 can be assembled to the external equipment such as the welding machine 100 by riveting.

[0079] In some embodiments, along the installation direction L3, the first blade 101 extends with a mounting portion 1012. By providing the mounting portion 1012, it is convenient to install the first blade 101. In some other embodiments, the first blade 101 extends with two mounting portions 1012, and the two mounting portions 1012 are distributed at both ends of the first blade 101 along the installation direction L3, so as to further facilitate the installation of the first blade 101.

[0080] A feasible way for the installation portion 1012 extending from the first blade 101 to facilitate its installation is that the shutter 1 further includes a frame 103, the frame 103 is provided with an assembly hole 1031, the plurality of first blades 101 are arranged in the assembly hole 1031, and the plurality of second blades 102 are arranged in the assembly hole 1031; the frame 103 extends an assembly portion 1032 toward the assembly hole 1031, the assembly portion 1032 is provided with an assembly groove 1033, and the installation portion 1012 is clamped in the assembly groove 1033. When the installation portion 1012 is extended from both ends of the first blade 101 along the installation direction L3, the number of the assembly portions 1032 is two, the number of the assembly grooves 1033 is twice the number of the first blade 101, and one installation portion 1012 corresponds to one assembly groove 1033.

[0081] It is worth noting that when assembling the first blade 101 and the frame 103, the mounting portion 1012 of the first blade 101 can be first clamped in the assembly groove 1033, and then the retaining angle 1011 can be connected to the assembly portion 1032 of the frame 103 by riveting or screwing.

[0082] In some embodiments, one end of the first blade 101 away from the second blade 102 is bent downward to form a first baffle 1013. The first baffle 1013 can enhance the waterproof and dustproof function of the shutter 1 on the one hand, and effectively reduce the wind from between the multiple first blades 101 to between the multiple second blades 102 on the other hand, thereby effectively preventing backflow.

[0083] In some other embodiments, the first baffle 1013 extends to a second baffle 1014 in a direction close to the second blades 102. The first baffle 1013 and the second baffle 1014 can further enhance the waterproof and dustproof function of the shutter 1 on the one hand, and further reduce the wind from between the first blades 101 to between the second blades 102 on the other hand, so as to further prevent backflow.

[0084] For the second blade 102, see Figure 7 In some embodiments, a stop bar 1021 extends upward from one end of the second blade 102 away from the first blade 101 , and the stop bar 1021 can further block water or dust.

[0085] In some embodiments, the shutter 1 further includes a first mounting frame 104 and a second mounting frame 105, the first mounting frame 104 and the second mounting frame 105 are arranged at intervals, and the plurality of second blades 102 are connected to the first mounting frame 104 and the second mounting frame 105. Through the first mounting frame 104 and the second mounting frame 105, the first mounting frame 104, the second mounting frame 105 and the plurality of second blades 102 can be used as a whole, which is convenient for assembly.

[0086] When the shutter 1 is provided with a frame 103 , the first mounting frame 104 and the second mounting frame 105 may be connected to the frame 103 , thereby achieving connection between the plurality of second blades 102 and the frame 103 .

[0087] In summary, the shutter 1 provided in the embodiment of the present application includes a plurality of first blades 101 and a plurality of second blades 102, that is, a two-layer waterproof and dustproof structure is formed, which has a good waterproof and dustproof effect compared to the single-layer structure in the prior art. In addition, since the first blade 101 and the second blade 102 are arranged in parallel, the ventilation effect of the shutter 1 is not affected. That is, compared with the prior art, the shutter 1 provided in the embodiment of the present application has both enhanced waterproof and dustproof performance and ventilation effect. When the shutter 1 is applied to the welding machine 100, the waterproof and dustproof performance of the welding machine 100 can be enhanced, and the heat dissipation and ventilation effect inside the welding machine 100 can be taken into account.
