It should be understood that those skilled in the art may modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation of the present invention.

[0044] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0045] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides a converter, including: a converter window 2, a cabinet 1, a heat dissipation duct 3, a fan 7, a baffle 4 and a blowing component.

[0046] Specifically, the inverter window 2 is arranged on the side wall of the cabinet 1; the heat dissipation duct 3 is arranged on the cabinet 1 and is connected to the interior of the cabinet 1; the fan 7 is arranged at one end of the heat dissipation duct 3, and the baffle 4 is arranged at the other end; the baffle 4 is rotatably arranged in the heat dissipation duct 3; the blowing component is connected to the baffle 4, and is connected to the heat dissipation duct 3 through the baffle 4, and the blowing component is located on the inner side of the inverter window 2.

[0047] This embodiment provides a matching structure of a fan 7, a baffle 4 and a blowing assembly on the converter, so that the airflow generated by the fan 7 can be used to clean the converter window 2 without manual cleaning; and this embodiment has a simple structure.

[0048] In one embodiment, in combination Figure 1-Figure 4 As shown, the cabinet 1 includes a bottom plate and a plurality of side plates connected in sequence. Specifically, the cabinet 1 includes a bottom plate and a plurality of side plates connected in sequence; the side plates are fixed around the bottom plate and are arranged vertically with the bottom plate to form a cabinet structure; the inverter window 2 is opened on the side plate; the bottom plate is located in the middle of the cabinet structure, and the cabinet structure is divided into an independent first space and a second space; the inverter window 2 and the blowing component are arranged in the first space; the heat dissipation duct 3 is arranged in the second space, and one end of the heat dissipation duct 3 passes through the bottom plate and extends to the first space; the connecting piece is arranged on the bottom plate.

[0049] In addition, this embodiment divides the cabinet 1 (ie, the cabinet structure) into independent spaces through the bottom plate, which can effectively prevent dust generated during the cleaning process from entering the interior of the device, protect the internal components of the device, and extend the service life of the device.

[0050] In a specific example, continue to refer to Figure 4 As shown, the blowing assembly includes: a vent pipe 5 and a blowing member 8. Specifically, the baffle 4 is provided with a through hole; one end of the vent pipe 5 is connected to the through hole, and the other end passes through the cabinet 1 and is connected to the blowing member 8; the blowing member 8 is located inside the inverter window 2. In this embodiment, by providing the structure of the vent pipe 5 and the blowing member 8, the through hole of the baffle 4 and the blowing member 8 form an airflow channel, which can accurately guide the airflow generated by the fan 7 to the inverter window 2, thereby improving the cleaning efficiency.

[0051] Further, combined with Figure 5-Figure 6 As shown, the blowing member 8 includes a device plate 81, a blowing hole 83 and an air nozzle 82. Specifically, the blowing hole 83 is provided on the side of the device plate 81 close to the inverter window 2, and the blowing hole 83 is arranged opposite to the inverter window 2; the air nozzle 82 is provided on the side of the device plate 81 away from the inverter window 2; the air nozzle 82 is connected to the blowing hole 83; and the end of the vent pipe 5 away from the through hole is connected to the air nozzle 82. In this embodiment, by arranging the blowing hole 83 and the air nozzle 82 on the device plate 81, and making the blowing hole 83 arranged opposite to the inverter window 2, the airflow can act more concentratedly on the surface of the inverter window 2, thereby improving the cleaning effect.

[0052] In a specific example, there are multiple inverter wind windows 2.

[0053] In this embodiment, the blowing assembly further includes a plurality of connecting pipes 9 and a plurality of blowing parts 8. Specifically, one end of the vent pipe 5 away from the through hole is connected to the plurality of connecting pipes 9; the blowing parts 8 are arranged one-to-one with the inverter window 2 and are located inside the inverter window 2; one end of the connecting pipe 9 away from the vent pipe 5 is connected to the corresponding blowing part 8. In this embodiment, by providing a plurality of inverter windows 2 and corresponding blowing parts 8 and adopting a connecting pipe 9 connection structure, a plurality of inverter windows 2 can be cleaned at the same time, thereby improving cleaning efficiency and saving cleaning time.

[0054] In this embodiment, the through hole on the baffle 4 and the vent pipe 5 are provided to realize the compact connection between the blowing assembly and the baffle 4 and the connecting pipe 9, thereby saving space and improving the compactness of the overall design. The vent pipe 5 and the connecting pipe 9 enable the airflow to be efficiently distributed from the fan 7 to each blowing member 8, thereby ensuring the cleaning effect of the inverter window 2. The blowing member 8 is provided corresponding to the inverter window 2, thereby ensuring that the cleaning airflow can accurately act on the inverter window 2, thereby improving the cleaning efficiency and effect.

[0055] In this embodiment, the blowing assembly further includes a connecting piece. Specifically, the connecting piece is fixed to the cabinet 1; a plurality of connecting pipes 9 are arranged inside the cabinet 1, and the connecting pipes 9 are all connected to the connecting piece; an end of the connecting piece away from the connecting pipe 9 is connected to the ventilation pipe 5; and the connecting pipe 9 is located outside the cabinet 1. By providing the connecting piece, a plurality of connecting pipes 9 and the ventilation pipe 5 form a stable connection structure, ensuring uniform airflow distribution and improving the synchronous cleaning effect of the plurality of inverter windshields 2.

[0056] By using the connecting piece, multiple connecting pipes 9 can be connected to one point, simplifying the pipeline layout and making the installation and maintenance of the entire system more convenient. The setting of the connecting piece helps to optimize the use of the internal space of the cabinet 1, making the pipeline layout more compact and reducing the occupation of the internal space of the cabinet 1.

[0057] In addition, combined Figure 7 As shown, this embodiment further includes a cleaning component; the cleaning component includes a brush 13. Specifically, the brush 13 is fixedly connected to the air blowing component, and the brush 13 is located outside the inverter window 2, and the bristles of the brush 13 are in contact with the surface of the inverter window 2. By providing the brush 13 and combining air blowing cleaning, stubborn stains on the surface of the inverter window 2 can be better removed, thereby improving the cleaning effect.

[0058] In addition, the bristles of the brush 13 fit the inverter window 2, which can effectively remove pollutants on the surface of the inverter window 2 and improve the cleaning effect.

[0059] As a preferred embodiment, Figure 8 As shown, this embodiment also includes a driving assembly for driving the blowing assembly to perform reciprocating motion.

[0060] Specifically, the driving assembly includes a driving motor 10, a driving rod 12 and a slide plate 11; the driving motor 10 is fixed to the cabinet 1, and the output end is connected to the driving rod 12; one end of the driving rod 12 is rotatably arranged on the cabinet 1, and is arranged in parallel with the inverter window 2; the blowing assembly is threadedly connected to the driving rod 12; the inverter window 2 is provided with a slide groove 15; one end of the slide plate 11 is connected to the driving rod 12, and the other end is slidably connected to the slide groove 15. This embodiment realizes the reciprocating motion of the blowing assembly through the driving assembly, so that the cleaning range is larger and the cleaning is more uniform. The design of the threaded connection and the slide groove 15 structure ensures the stability and reliability of the reciprocating motion.

[0061] Since the air blowing component is fixedly connected to the brush 13 of the cleaning component, cleaning can be performed while blowing, thereby improving the cleaning effect. This embodiment reduces the need for manual cleaning by automatically controlling the air blowing component and the cleaning component, and reduces the operation and maintenance costs and labor intensity. The cleaning process can be started through remote control instructions, and the operator does not need to directly contact the equipment, which improves the convenience and safety of operation.

[0062] Preferably, the drive rod 12 comprises a threaded rod or a reciprocating screw. The threaded rod or the reciprocating screw can provide precise linear motion control, ensuring that the movement of the air blowing assembly and the brush 13 during the cleaning process is uniform and controllable. The threaded rod and the reciprocating screw have high transmission efficiency, which can ensure that the power of the drive motor 10 is effectively transmitted to the air blowing assembly and the brush 13, thereby improving the cleaning efficiency.

[0063] In addition, the driving rod 12 is parallel to the length direction of the inverter window 2. Therefore, the setting of the slide plate 11 not only improves the stability of the device, but also enables the blowing assembly to move along the entire length direction of the inverter window 2, thereby expanding the cleaning range and ensuring that every part of the inverter window 2 can be cleaned.

[0064] Preferably, it also includes a plurality of sliding rods 14; the plurality of sliding rods 14 are spaced apart on one side of the device plate 81 close to the inverter window 2, and are distributed on both sides of the blowing hole 83; a sliding groove 16 is also provided on the inverter window 2, one of the sliding rods 14 passes through the sliding groove 16 and is fixedly connected to one end of the brush 13, and the other sliding rod 14 passes through the slide plate 11 and the sliding groove 15 and is fixedly connected to the other end of the brush 13.

[0065] The setting of the slide bar 14 can ensure the relative position between the cleaning component and the inverter window 2 is stable. Furthermore, the setting of the slide bar 14 enables the blowing member 8 to maintain better contact with the surface of the inverter window 2. No matter how the curvature of the surface of the inverter window 2 changes, the slide bar 14 can adapt to ensure the cleaning effect. The sliding connection between the slide bar 14 and the inverter window 2 provides a stable support, so that the blowing member 8 is not easy to shake during the cleaning process, and the cleaning stability and accuracy are improved. The setting of the slide bar 14 reduces the wear that may occur when the device plate 81 is in direct contact with the inverter window 2, and prolongs the service life of the device plate 81 and the inverter window 2.

[0066] Preferably, the present embodiment further comprises a control motor 6, the control motor 6 being fixed to the outer wall of the heat dissipation duct 3; the output shaft of the control motor 6 passes through the side wall of the heat dissipation duct 3 and is connected to the baffle 4. The baffle 4 is controlled to rotate by the control motor 6 to achieve precise control of the airflow direction, which can ensure normal heat dissipation function and can be converted to a cleaning function when needed.

[0067] The heat dissipation duct 3 is cylindrical in structure; the baffle 4 is disc-shaped. The cylindrical heat dissipation duct 3 helps to reduce the resistance of air flow, improve the air circulation efficiency, and thus enhance the heat dissipation effect. The circular baffle 4 can rotate smoothly, reducing the safety risks caused by sharp edges that may occur during operation.

[0068] In addition, if Fig. 9 As shown, this embodiment also provides a method for self-cleaning a windshield of a converter, which specifically includes the following steps:

[0069] S1. Provide a converter, including a converter window 2, a heat dissipation duct 3, a fan 7, a baffle 4 and a blowing assembly;

[0070] S2, controlling the baffle plate 4 to rotate until the baffle plate 4 is in sealing contact with the inner wall of the heat dissipation air duct 3, so that the airflow generated by the fan 7 is output through the blowing assembly;

[0071] S3, using the blowing assembly to clean impurities on the surface of the inverter window 2 by blowing.

[0072] Furthermore, the present embodiment also includes: the inverter also includes a driving component and a cleaning component, and the cleaning component includes a brush 13; the driving component and the cleaning component of the inverter are started, and the brush 13 is driven to reciprocate and clean the surface of the inverter wind window 2 while blowing air to clean the impurities on the surface of the inverter wind window 2.

[0073] Preferably, when entering the cleaning mode, the rotation speed of the fan 7 is lower than that of the normal working state.

[0074] Preferably, when cleaning is finished, the baffle 4 is reset, the blowing assembly and the cleaning assembly are closed, and the airflow generated by the fan 7 is directly output through the heat dissipation duct 3.

[0075] The present embodiment provides a method for self-cleaning the inverter window 2, which can realize automatic cleaning of the inverter window 2 without affecting the normal operation of the equipment. By controlling parameters such as the speed of the fan 7 and the position of the baffle 4, the cleaning process is ensured to be safe and reliable. After the cleaning is completed, the system can automatically resume normal working state, which is simple to operate and highly practical. By combining air blowing cleaning with mechanical cleaning, the cleaning effect is better, and the cleaning mode can be flexibly adjusted according to actual needs.

[0076] In this embodiment, when the device receives a cleaning instruction, it enters the cleaning mode. The control motor 6 is started, and the baffle 4 is turned to Figure 3In the state, the baffle 4 blocks the air outlet of the heat dissipation duct 3. At this time, the air blown by the fan 7 does not enter the cabinet 1, but transmits the wind to the blowing part 8 through the ventilation pipe 5. When the device enters the cleaning mode, the rotation speed of the fan 7 is lower than that in the normal working state. The rotation speed in the normal working state can, for example, refer to the rotation speed when the fan 7 is turned on after the baffle 4 is reset (can be set manually), that is, the required air volume of the blowing part 8 is met. During cleaning, the brush 13 and the blowing part 8 are driven by the driving motor 10 to perform reciprocating cleaning along the length direction of the inverter window 2. At the end of cleaning, the baffle 4 is reset under the action of the control motor 6, that is, the baffle 4 is opened as Figure 2 As shown, the wind enters the cabinet (the heat dissipation duct 3 is connected to the designated position, and the cabinet here refers to the heat dissipation by blowing air to the designated position), and at the same time the brush 13 and the blowing member 8 stop working, the device exits the cleaning mode and maintains the normal working state.
