[0002] A compressor is a device that increases gas pressure through mechanical action. Its core function is to compress low-pressure gas into high-pressure gas, which is accompanied by an increase in temperature. It is a key piece of equipment in industrial production, such as pneumatic systems and energy transmission. The freezer compartment of a refrigerator requires regular cleaning of the compressor's exhaust pipe.
[0003] The compressor inside the refrigerator freezes the freezer compartment through a serpentine exhaust pipe. Over time, a lot of frost will accumulate on the outside of the exhaust pipe. To avoid affecting the internal space of the refrigerator, it needs to be wiped clean after each time the door is opened.
[0004] However, the compressor exhaust pipe needs to be wiped clean every time the door is opened to prevent frost from forming. Unfortunately, it's easy to forget to wipe the compressor exhaust pipe, leading to frost buildup on the outside and affecting the freezer compartment. Therefore, this invention proposes a refrigerator compressor exhaust pipe with a self-cleaning function. Utility Model Content
[0005] The purpose of this invention is to address the problem in the prior art that the compressor exhaust pipe needs to be wiped every time the door is opened to prevent frost from forming. However, it is inevitable that the wiping will be forgotten, which will cause frost to adhere to the outside of the exhaust pipe and affect the freezer space. The invention proposes a refrigerator compressor exhaust pipe with a self-cleaning function.
[0006] The technical solution of this utility model is as follows: A refrigerator compressor exhaust pipe with self-cleaning function includes a refrigerator body, a compressor body fixedly connected to one side of the refrigerator body, an exhaust pipe body fixedly connected to the compressor body near the refrigerator body, the exhaust pipe body being disposed inside the refrigerator body, and a protective box fixedly connected to the side of the compressor body away from the refrigerator body, the protective box being fixedly connected to one side of the refrigerator body.

There are multiple sets of wave grooves arranged in a linear array.
[0008] A force-bearing block is fixedly connected to one side of the scraper, and a pushing block is slidably connected inside the refrigerator body. There are multiple pushing blocks arranged in a linear array. The pushing blocks are arranged in a trapezoidal shape, and the oblique surface of the pushing block is located inside the refrigerator body.
[0009] The pusher block is fixedly connected to a pusher plate at the end away from the oblique cut surface, and a pusher assembly is provided on the outside of the pusher plate.
[0010] Optionally, the pushing assembly includes a pushing spring, and a protective shell is fixedly connected to the end of the pushing spring away from the pushing plate. The protective shell is fixedly connected to the outside of the refrigerator body.
[0011] Optionally, a sliding rod is fixedly connected to the push plate near the push spring. The sliding rod is disposed inside the push spring and is slidably connected inside the protective shell.
[0012] Optionally, a screw is rotatably connected inside the protective shell, with one end of the screw rotatably connected to one side of the refrigerator body, and the outside of the screw rotatably connected to the inside of the push plate.
[0013] Optionally, a telescopic spring is fixedly connected to one end of the scraper, and the end of the telescopic spring away from the scraper is fixedly connected inside the sliding beam.

[0033] Example
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, this utility model proposes a refrigerator compressor exhaust pipe with self-cleaning function, including a refrigerator body 1. A compressor body 5 is fixedly connected to one side of the refrigerator body 1. An exhaust pipe body 4 is fixedly connected to the compressor body 5 near the refrigerator body 1. The exhaust pipe body 4 is located inside the refrigerator body 1 and can perform refrigeration inside the refrigerator body 1. A protective box 2 is fixedly connected to the side of the compressor body 5 away from the refrigerator body 1. The protective box 2 is fixedly connected to one side of the refrigerator body 1. A sliding groove 16 is opened inside the refrigerator body 1. A sliding beam 6 is slidably connected inside the sliding groove 16. A scraper 7 is slidably connected inside the sliding beam 6. The sliding beam 6 drives the scraper 7 to slide along the sliding groove 16. One side of the scraper 7 abuts against the outside of the exhaust pipe body 4, and the scraper 7 can clean the exhaust pipe. To remove frost from the surface of the exhaust pipe body 4, a undulating groove 18 is provided on the scraper 7 near the exhaust pipe body 4. Multiple sets of undulating grooves 18 are arranged in a linear array to enhance the cleaning effect of the scraper 7 on the exhaust pipe body 4. A force-bearing block 17 is fixedly connected to one side of the scraper 7. A pushing block 8 is slidably connected inside the refrigerator body 1. Multiple pushing blocks 8 are arranged in a linear array. The pushing block 8 can repeatedly push the force-bearing block 17 to drive the scraper 7 to slide inside the sliding beam 6. The pushing block 8 is trapezoidal in shape, and the inclined surface of the pushing block 8 is located inside the refrigerator body 1. The inclined surface of the pushing block 8 will not affect the movement of the sliding beam 6. A pushing plate 9 is fixedly connected to the end of the pushing block 8 away from the inclined surface. The pushing plate 9 can control multiple pushing blocks 8 to move together. A pushing component is provided on the outside of the pushing plate 9.
[0035] For further details, please refer to Figure 3 and Figure 4 The pushing component includes a pushing spring 10. A protective shell 12 is fixedly connected to the end of the pushing spring 10 away from the pushing plate 9. The pushing spring 10 can push the pushing plate 9 inside the protective shell 12 to drive the pushing block 8 to move telescopically. The protective shell 12 is fixedly connected to the outside of the refrigerator body 1. The protective shell 12 can fix the pushing spring 10 and the pushing plate 9 to a limited position outside the refrigerator body 1. A sliding rod 11 is fixedly connected to the side of the pushing plate 9 near the pushing spring 10. The sliding rod 11 can limit the movement of the pushing plate 9. The sliding rod 11 is located inside the pushing spring 10 and is slidably connected inside the protective shell 12. The protective shell 12 can control the movement of the pushing plate 9. A screw 13 is rotatably connected inside the protective shell 12. One end of the screw 13 is rotatably connected to one side of the refrigerator body 1, and the outside of the screw 13 is rotatably connected to the inside of the pushing plate 9. The screw 13 can fix the telescopic position of the pushing block 8, and the screw 13 can also slide inside the protective shell 12.
[0036] For further details, please refer to Figures 3 to 5One end of the scraper 7 is fixedly connected to a telescopic spring 15. After the pushing block 8 is embedded inside the sliding beam 6, it will push the force block 17 to drive the scraper 7 to squeeze the telescopic spring 15. The end of the telescopic spring 15 away from the scraper 7 is fixedly connected inside the sliding beam 6. The side of the scraper 7 near the telescopic spring 15 is fixedly connected to a telescopic rod 14. The telescopic rod 14 can assist the movement of the scraper 7 and the extension and retraction of the telescopic spring 15. The end of the telescopic rod 14 away from the scraper 7 is fixedly connected inside the sliding beam 6. The telescopic rod 14 is set inside the telescopic spring 15. The side of the sliding beam 6 away from the scraper 7 is fixedly connected to a slide rail 20. An adjusting rod 19 is slidably connected inside the slide rail 20. The adjusting rod 19 can slide along the slide rail 20 to control the scraper 7 and can also change the angle. The end of the adjusting rod 19 away from the slide rail 20 is rotatably connected to a rotating block 21. The rotating block 21 is fixedly connected to the side of the door panel 3 near the refrigerator body 1. When the door panel 3 is opened, the rotating block 21 rotates at the end of the adjusting rod 19 to drive the scraper 7 to slide without affecting the opening and closing.
[0037] In this embodiment, when in use, the compressor body 5 inside the protective box 2 is activated, allowing the exhaust pipe body 4 to cool inside the refrigerator body 1. At this time, the door panel 3 can be rotated along one side of the refrigerator body 1, thus opening the refrigerator body 1 and freezing food and beverages that need to be frozen.
[0038] Each time the door panel 3 is opened, the door panel 3 will rely on the rotating block 21 to drive the adjusting rod 19 to slide along the slide rail 20, thereby driving the sliding beam 6 to slide along the slide groove 16. In this way, the scraper 7 and the wave groove 18 will pass through the bottom of the exhaust pipe body 4, so that the scraper 7 can clean the frosty area of the exhaust pipe body 4. When the door panel 3 is closed, the adjusting rod 19 will also rely on the rotating block 21 to slide inside the slide rail 20, which will push the scraper 7 to reset.
[0039] When the sliding beam 6 slides along the inside of the sliding groove 16, the sliding beam 6 will contact the inclined surface of the push block 8. At this time, the push block 8 can be squeezed, causing the push block 8 to drive the push plate 9 to slide along the inside of the protective shell 12. When the push block 8 is aligned with the sliding beam 6, it will push the push block 8 inside the protective shell 12 through the push spring 10, causing the push block 8 to push the force block 17 to drive the scraper 7 to move inside the sliding beam 6. When the scraper 7 moves, it will squeeze the telescopic spring 15 and the telescopic rod 14, causing the scraper 7 to disengage from the pushing position of the push block 8. After that, the telescopic rod 14 and the telescopic spring 15 will drive the scraper 7 to reset. In this way, the scraper 7 has a better cleaning effect on the exhaust pipe body 4.
[0040] When it is necessary to close the door panel 3, in order to avoid the push block 8 affecting the movement of the sliding beam 6, the sliding rod 11 can be pulled so that the sliding rod 11 drives the push plate 9 and the push block 8 to slide along the inside of the refrigerator body 1, so that the push block 8 is level with the inside of the sliding groove 16, and the sliding beam 6 can slide normally inside the sliding groove 16.
[0041] When the pushing distance of the push block 8 needs to be limited, the screw 13 can be rotated to move the push plate 9, thus fixing the position of the push block 8. The way the screw 13 slides inside the protective shell 12 will not affect the movement of the push plate 9 and the push block 8.
[0042] It should be noted that the opening and closing of the door panel 3 drives the rotating block 21 to pull the adjusting rod 19 to slide along the inside of the slide rail 20, thereby driving the sliding beam 6 to slide along the inside of the sliding groove 16. In this way, the sliding beam 6 will drive the scraper 7 to clean the frost condensed on the surface of the exhaust pipe body 4. When the sliding beam 6 moves, the pushing block 8 will repeatedly push the scraper 7, allowing the scraper 7 to slide inside the sliding beam 6. In this way, the scraper 7 can rely on the wave groove 18 to enhance the cleaning effect on the exhaust pipe body 4, increasing the automatic cleaning effect on the surface of the exhaust pipe body 4.
[0043] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
