Description

Technical Field

[0001] This utility model relates to a cleaning mechanism for an evaporator, belonging to the field of evaporator technology. Background Technology

[0002] During the daily use of evaporators, the maintenance channel, as a crucial passage for equipment maintenance and repair, easily accumulates impurities and dirt, affecting normal operation and maintenance. However, existing evaporator units lack effective cleaning structures for the maintenance channel, making it impossible to clean it. Cleaning is limited to manual disassembly or simple wiping, which struggles to reach the hard-to-reach corners and complex structures within the channel, resulting in poor cleaning effectiveness. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a cleaning mechanism for evaporators. This mechanism addresses the lack of an effective cleaning structure for maintenance channels in existing technologies, which prevents proper cleaning of these channels. The existing methods rely solely on manual disassembly or simple wiping, making it difficult to clean the hard-to-reach corners and complex structures within the channels, resulting in poor cleaning performance.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: a cleaning mechanism for an evaporator, including an evaporator, a maintenance channel connected to the evaporator, an installation plate fixedly installed on the maintenance channel, a limit groove opened on the installation plate, a fixing plate installed on one side of the maintenance channel, a limit plate fixedly installed at one end of the fixing plate, the limit plate can be inserted into the limit groove, a limiting structure for limiting the limit plate is provided on the installation plate, a spray pipe is provided on the side of the fixing plate facing the maintenance channel, a plurality of spray nozzles are provided on the spray pipe, and a rotating structure for driving the spray pipe to rotate is provided on the installation plate.

[0005] By adopting the above technical solution, when it is necessary to clean the maintenance channel on the evaporator, the fixing plate is first inserted into the limiting groove along with the limiting plate. At the same time, the fixing plate also moves the spray pipe and nozzle into the maintenance channel. Then, the limiting structure limits the limiting plate. Subsequently, the cleaning liquid in the spray pipe is sprayed out through the nozzle to clean the inner wall of the maintenance channel. At the same time, the rotating structure drives the nozzle to rotate, which can expand the cleaning coverage area, avoid dead corner residue, and improve cleaning efficiency and thoroughness.

[0006] The present invention is further configured such that: the limiting structure includes a sliding groove, a locking block, a lever plate and a locking slot, the sliding groove is opened on the mounting plate and communicates with the limiting groove, the locking block is slidably disposed inside the sliding groove, the locking slot is opened on the limiting plate, and one end of the locking block can extend into the inside of the limiting groove and be inserted into the locking slot.

[0007] The present invention is further configured such that: a guide groove is provided on the inner wall of the sliding groove, and guide plates are fixedly provided on both sides of the block. The guide plates are slidably connected to the guide groove, and a spring is fixedly provided between the side of the guide plate away from the sliding surface and the guide groove.

[0008] By adopting the above technical solution, pulling the lever causes the locking block to move away from the locking slot in the sliding groove. When the locking block moves, it causes the guide plate to slide in the guide groove. During the sliding process, the guide plate compresses the spring, thereby separating the locking block from the locking slot and thus canceling the limitation of the limiting plate.

[0009] The present invention is further configured such that: the rotating structure includes a rotating shaft and a rotating disk, the rotating shaft is rotatably mounted on the fixed plate, one end of the rotating shaft extends into the maintenance channel and is fixedly connected to the spray pipe, and the other end of the rotating shaft extends to the end of the fixed plate away from the spray pipe and is fixedly mounted on the rotating disk.

[0010] The present invention is further configured such that a conveying hole communicating with a spray pipe is provided through the rotating disk and the rotating shaft.

[0011] By adopting the above technical solution, rotating the rotating disk drives the rotating shaft to rotate, which in turn drives the spray pipe to rotate.

[0012] The present invention is further configured such that: a connecting plate is fixedly installed on the spray pipe, and a scraper is provided on one side of the connecting plate, the scraper being slidably connected to the inner wall of the maintenance channel.

[0013] The present invention is further configured such that: a positioning plate is fixedly provided on the scraper, a positioning groove is provided on the connecting plate, the positioning plate is slidably connected to the positioning groove, and a limit bolt is threadedly connected to the connecting plate, one end of the limit bolt can extend into the positioning groove and abut against the positioning plate.

[0014] By adopting the above technical solution, the spray pipe rotates synchronously with the scraper, which scrapes away impurities from the inner wall of the maintenance channel, effectively removing firmly attached impurities, improving the cleaning effect, and ensuring the cleanliness of the inner wall of the maintenance channel.

[0015] The beneficial effects of this utility model are as follows: When it is necessary to clean the maintenance channel on the evaporator, the fixing plate is first inserted into the limiting groove along with the limiting plate. At the same time, the fixing plate also moves the spray pipe and nozzle into the maintenance channel. Then, the limiting structure limits the limiting plate. Subsequently, the cleaning liquid in the spray pipe is sprayed out through the nozzle to clean the inner wall of the maintenance channel. At the same time, the rotating structure drives the nozzle to rotate, which can expand the cleaning coverage area, avoid dead corner residue, and improve cleaning efficiency and thoroughness.

[0022] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] like Figures 1 to 5 As shown, a cleaning mechanism for an evaporator includes an evaporator 1. A support leg 1071 is fixedly installed at the bottom of the evaporator 1 to support it. A maintenance channel 2 is connected to the evaporator 1. An installation plate 3 is fixedly installed on the maintenance channel 2. A limiting groove 4 is horizontally opened on the installation plate 3. A fixing plate 5 is installed on one side of the maintenance channel 2. A limiting plate 6 is fixedly installed at one end of the fixing plate 5. The limiting plate 6 can be inserted into the limiting groove 4. A limiting structure is provided on the installation plate 3 to limit the limiting plate 6. A spray pipe 7 is provided on the side of the fixing plate 5 facing the maintenance channel 2. A plurality of spray nozzles 8 are provided on the spray pipe 7. A rotating structure is provided on the installation plate 3 to drive the spray pipe 7 to rotate.

[0024] like Figure 5As shown, the limiting structure includes a sliding groove 1011, a locking block 1012, a lever 1013, and a locking slot 1014. The sliding groove 1011 is vertically opened on the mounting plate 3 and communicates with the limiting groove 4. The locking block 1012 is slidably disposed inside the sliding groove 1011 and slides along the opening direction of the sliding groove 1011. The locking slot 1014 is vertically opened on the limiting plate 6. One end of the locking block 1012 can extend into the interior of the limiting groove 4 and be inserted into the locking slot 1014. When the limiting plate 6 abuts against the limiting groove 4, the locking slot 1014 is aligned with the locking block 1012. A guide groove 1021 is provided on the inner wall of the sliding groove 1011. The guide groove 1021 and the sliding groove 1011 are opened in the same direction. Guide plates 1022 are fixedly provided on both sides of the locking block 1012. The guide plates 1022 are slidably connected to the guide groove 1021. A spring 1023 is fixedly provided between the side of the guide plate 1022 away from the sliding surface and the guide groove 1021. The spring 1023 is in a tensioned state when it is not under force.

[0025] like Figure 4 As shown, the rotating structure includes a rotating shaft 1031 and a rotating disk 1032. The rotating shaft 1031 is rotatably mounted on the fixed plate 5. One end of the rotating shaft 1031 extends into the maintenance channel 2 and is fixedly connected to the spray pipe 7. The other end of the rotating shaft 1031 extends to the fixed plate 5 at the end away from the spray pipe 7 and is fixedly mounted on the rotating disk 1032. A handle is eccentrically fixed at the end of the rotating disk 1032 away from the rotating shaft 1031.

[0026] like Figure 4 As shown, a conveying hole 1041 communicating with the spray pipe 7 is provided through the rotating disk 1032 and the rotating shaft 1031. The conveying hole 1041 is connected to an external water pump, which conveys the cleaning fluid to the spray pipe 7 through the conveying hole 1041. A connecting plate 1051 is fixedly installed on the spray pipe 7, and a scraper 1052 is provided on one side of the connecting plate 1051. The scraper 1052 is slidably connected to the inner wall of the maintenance channel 2.

[0027] like Figure 3 As shown, a positioning plate 1061 is fixedly installed on the scraper 1052, and a positioning groove 1062 is opened on the connecting plate 1051. The positioning plate 1061 is slidably connected to the positioning groove 1062. A limit bolt 1063 is threadedly connected to the connecting plate 1051. One end of the limit bolt 1063 can extend into the positioning groove 1062 and abut against the positioning plate 1061. When it is necessary to disassemble the scraper 1052, the limit bolt 1063 is rotated to move away from the positioning plate 1061, thereby canceling the limit on the positioning plate 1061. The positioning plate 1061 can then be pulled to move away from the positioning groove 1062, thus completing the removal of the scraper 1052 and facilitating its replacement or maintenance.

[0028] When the maintenance channel 2 on the evaporator 1 needs to be cleaned, the fixing plate 5 is first inserted into the limiting plate 6 into the limiting groove 4. At the same time, the fixing plate 5 also moves the spray pipe 7 and the nozzle 8 into the maintenance channel 2. Then, the limiting structure limits the limiting plate 6. Subsequently, the external water pump provides cleaning fluid to the spray pipe 7, and then the nozzle 8 sprays it out to clean the inner wall of the maintenance channel 2. At the same time, the rotating structure drives the nozzle 8 to rotate, which can expand the cleaning coverage area, avoid dead corner residue, and improve cleaning efficiency and thoroughness.

[0029] Pulling the lever 1013 causes the locking block 1012 to move away from the slot 1014 in the sliding groove 1011. When the locking block 1012 moves, it causes the guide plate 1022 to slide in the guide groove 1021. During the sliding process, the guide plate 1022 compresses the spring 1023, thereby separating the locking block 1012 from the slot 1014. This cancels the limitation on the limiting plate 6, and the fixing plate 5 can then be removed.

[0030] Rotating the rotating disk 1032 drives the rotating shaft 1031 to rotate, which in turn drives the spray pipe 7 to rotate.

[0031] When the spray pipe 7 rotates, it synchronously drives the scraper 1052 to rotate. The scraper 1052 scrapes away the impurities on the inner wall of the maintenance channel 2, effectively removing firmly attached impurities, improving the cleaning effect, and ensuring the cleanliness of the inner wall of the maintenance channel 2.
