Description

Technical Field

[0001] The invention relates to the technical field of refrigeration units, and in particular to an energy-saving refrigeration unit with a refrigerant recovery function. Background Art

[0002] When the refrigerant in the air conditioner needs to be replaced, when the air conditioner breaks down and needs to be repaired, or when the air conditioner is scrapped, the refrigerant in the air conditioner needs to be recovered to avoid the refrigerant in the air conditioner being released into the atmosphere and causing damage to the environment. At the same time, the refrigerant can be reused after recovery, saving costs and reducing energy consumption.

[0003] In the prior art, the name disclosed in the application number: CN202410532861.8 is: an energy-saving refrigeration unit with a refrigerant recovery function, which includes a refrigerator main body, and the interior of the refrigerator main body is equipped with a refrigerant recovery component connected to the condenser, and the refrigerant recovery component includes a recovery tank with a pressure regulating function and used to recover the refrigerant, and a quick recovery component. The side of the recovery tank is equipped with a pressure valve, and the side of the pressure valve is equipped with two delivery pipes for transporting the refrigerant. The present application recovers the refrigerant in the condenser by setting a refrigerant recovery component. At the same time, in order to prevent the refrigerant from remaining in the delivery pipe, a quick recovery component is set to squeeze the delivery pipe to clean the residual refrigerant in the delivery pipe. At the same time, the rolling component in the present application can rotate during operation, thereby changing the extrusion angle of the delivery pipe, which can prevent the delivery pipe from being broken by unidirectional extrusion.

[0004] However, in the prior art, although an energy-saving refrigeration unit with a refrigerant recovery function mentioned in application number: CN202410532861.8 can prevent the delivery pipe from being broken by unidirectional extrusion during actual use, the delivery pipe will still break after long-term repeated extrusion, so that the refrigerant will still leak from the broken delivery pipe, causing damage to the environment, so it needs to be improved.

[0034] The delivery pipe mechanism 3 includes a first hose 31, which is fixedly connected to the pressure valve 2 and the control valve 4 respectively. A circular ring block 33 is sleeved on the outer surface of the first hose 31, and a second hose 32 is sleeved on the outer surface of the circular ring block 33. One end of the second hose 32 is fixedly connected to the pressure valve 2, and the other end of the second hose 32 is fixedly connected to the control valve 4. A blocking block 34 is fixed between the circular ring blocks 33, and a rotating iron block 35 is hinged in the circular ring block 33. A movable moving block 6 is sleeved on the outer surface of the second hose 32, and a magnet block 36 for attracting the rotating iron block 35 is installed on the side of the moving block 6. The rotating mechanism 38 equipped with the rotating magnet block 36, when it is necessary to recycle the refrigerant, at this time, by opening the pressure valve 2 and the control valve 4, the refrigerant in the refrigerator is successively recovered into the recovery tank 1 through the control valve 4 and the first hose 31 and the pressure valve 2. After the initial recovery is completed, the control valve 4 is closed, and the magnet block 36 is driven by the rotating mechanism 38 to move to the top of the rotating iron block 35, so that the magnet block 36 attracts the rotating iron block 35 to rotate and move upward, and then the rotating iron block 35 flattens the first hose 31 on the blocking block 34, and then drives the moving block 6 as a whole, so that the moving block 6 passes through the rotating machine The mechanism 38 drives the magnet block 36 to move, and then the moving magnet block 36 drives the rotating iron block 35 to move as a whole through suction, so that the rotating iron block 35 drives the annular block 33 to move along the first hose 31 and the second hose 32, and the moving rotating iron block 35 squeezes the refrigerant in the first hose 31 into the recovery tank 1 for recycling. After recycling, the magnet block 36 is moved to the bottom of the rotating iron block 35 by the rotating mechanism 38, so that the magnet block 36 attracts the rotating iron block 35 to rotate downward, releasing the squeezing of the first hose 31. When the first hose 31 is repeatedly squeezed and ruptured, At this time, since the second hose 32 is sleeved on the outside of the first hose 31, the refrigerant inside the first hose 31 leaks into the second hose 32 through the rupture. Then, since the annular block 33 contacts the outer surface of the first hose 31 and the inner surface of the second hose 32 respectively, the annular block 33 can squeeze the leaked refrigerant back into the recovery tank 1 for recovery during the movement, thereby achieving the purpose of squeezing out the refrigerant inside the first hose 31, and avoiding the refrigerant from leaking from the rupture caused by repeated squeezing of the first hose 31, avoiding the refrigerant from leaking to the outside and causing environmental pollution.

[0035] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0036] Embodiment 2, as Figure 3 and Figure 7As shown, the rotating mechanism 38 includes a slide groove 386 opened inside the moving block 6, and a convex block 385 is movably sleeved inside the slide groove 386. One end of the convex block 385 is fixedly connected to a rack block 384, and one end of the rack block 384 is fixedly connected to the magnet block 36. The outer surface of the rack block 384 is meshingly connected to a gear block 383. A rotating rod 382 is fixed inside the gear block 383, and the other end of the rotating rod 382 is transmission-connected to a brake motor 381 fixed on the moving block 6. By starting the brake motor 381, the rotating rod 382 drives the gear block 383 to rotate, and then the gear block 383 drives the rack block 384 to rotate, so that the gear The bar block 384 drives the convex block 385 to rotate along the inner wall of the slide groove 386, so that the rack block 384 drives the magnet block 36 to move above the rotating iron block 35, so that the magnet block 36 attracts the rotating iron block 35 to squeeze the first hose 31 on the blocking block 34. When it is necessary to release the squeezing effect on the first hose 31, the brake motor 381 is started at this time, so that the rotating rod 382 drives the gear block 383 and the rack block 384 to drive the magnet block 36 to reset, so that the rotating rod 382 drives the magnet block 36 to move below the rotating iron block 35, and then the magnet block 36 attracts the rotating iron block 35 to rotate downward, thereby releasing the squeezing effect on the first hose 31.

[0037] Based on the second embodiment, the solution in the second embodiment is further detailed in combination with the following specific working method, as described below for details.

[0038] Embodiment three, as Figure 2 As shown, a support frame 5 is fixed to the bottom of the pressure valve 2 and the control valve 4, and a moving mechanism 37 for driving the moving block 6 is installed on the support frame 5. Through the design of the support frame 5, the support frame 5 can stably support the pressure valve 2 and the control valve 4, and then the pressure valve 2 and the control valve 4 can stably support the delivery pipe mechanism 3 as a whole, so that the refrigerant can be better discharged into the interior of the recovery tank 1 for recovery.

[0039] Based on the third embodiment, the solution in the third embodiment is further detailed in combination with the following specific working method, as described below for details.

[0040] Embodiment 4, as Figure 2As shown, the moving mechanism 37 includes a driving motor 371 fixed on the support frame 5, and a threaded rod 372 is transmission-connected to the driving motor 371. The other end of the threaded rod 372 penetrates the support frame 5 and is threadedly sleeved with the moving block 6. The moving mechanism 37 also includes a side round rod 373 sleeved inside the moving block 6, and the other end of the side round rod 373 is fixedly connected to the side of the support frame 5. By starting the driving motor 371, the threaded rod 372 drives the moving block 6 to move along the side round rod 373. At this time, the moving block 6 drives the rack block 384 to move through the convex block 385 and the slide groove 386, so that the rack block 384 drives the magnet block 36 to move, and then the magnet block 36 can drive the rotation of the first hose 31 that is attracted and squeezed. The iron block 35 moves, so that the residual refrigerant inside the first hose 31 is squeezed and discharged into the recovery tank 1 for recovery. When it is necessary to discharge the refrigerant inside the refrigerant of the first hose 31 into the recovery tank 1, the brake motor 381 is started to reset the rack block 384, so that the rack block 384 drives the magnet block 36 to move to the bottom of the rotating iron block 35, and then the magnet block 36 attracts the rotating iron block 35 to rotate downward, releasing the squeezing effect on the first hose 31, and starting the drive motor 371, so that the threaded rod 372 drives the moving block 6 to reset along the second hose 32, so that the refrigerant inside the refrigerant can be discharged into the recovery tank 1 through the pressure valve 2 and the second hose 32 and the control valve 4 in sequence.

[0041] Based on the fourth embodiment, the scheme in the fourth embodiment is further detailed in combination with the following specific working method, as described below for details.

[0042] Embodiment 5, as 8 and Fig. 9 As shown, the outer surface of the circular ring block 33 is fixedly sleeved with a first circular rubber 7, the outer surface of the first circular rubber 7 is in compression contact with the inner wall of the second hose 32, and the inner surface of the circular ring block 33 is fixedly sleeved with a second circular rubber 8, the inner surface of the second circular rubber 8 is in compression contact with the outer surface of the first hose 31. Through the design of the first circular rubber 7 and the second circular rubber 8, when the circular ring block 33 is driven to move along the first hose 31 and the second hose 32, the circular ring block 33 can flexibly contact the first hose 31 and the second hose 32 through the first circular rubber 7 and the second circular rubber 8 respectively, so that the circular ring block 33 can better seal the space between the first hose 31 and the second hose 32 through the first circular rubber 7 and the second circular rubber 8, and then the circular ring block 33 can push the leaked refrigerant between the first hose 31 and the first hose 31 into the recovery tank 1 for recovery through the first circular rubber 7 and the second circular rubber 8.

[0043] When used specifically, the present invention is used as an energy-saving refrigeration unit with a refrigerant recovery function. After the refrigerator stops working, the refrigerant in the refrigerator is discharged into the recovery tank 1 through the first hose 31 by opening the pressure valve 2 and the control valve 4. After the initial recovery is completed, the control valve 4 is closed, and then the brake motor 381 is started, so that the rotating rod 382 drives the gear block 383 to rotate, and then the gear block 383 drives the rack block 384 to rotate, so that the convex block 385 rotates along the inner wall of the slide groove 386 to limit the rack block 384, and then the rack block 384 drives the magnet block 36 to move above the rotating iron block 35, so that the magnet block 36 attracts the rotating iron block 35 to rotate upward, and then the rotating iron block 35 Block 35 squeezes the first hose 31 onto the blocking block 34, and then starts the driving motor 371, so that the threaded rod 372 drives the moving block 6 to move along the outer surface of the side round rod 373, and then the moving block 6 drives the rack block 384 to move through the convex block 385 and the slide groove 386, so that the rack block 384 drives the magnet block 36 to move, and then the magnet block 36 can drive the rotating iron block 35 to move, so that the rotating iron block 35 will gradually move and squeeze the first hose 31, and then the residual refrigerant inside the first hose 31 is squeezed and discharged into the recovery tank 1 for recovery, and the pressure valve 2 is closed after recovery, thereby achieving the purpose of fully discharging the refrigerant inside the first hose 31 and improving the refrigerant recovery effect of the device.

[0044] When the first hose 31 is repeatedly squeezed and ruptured, the refrigerant inside the first hose 31 will leak into the second hose 32 through the rupture, and then by opening the pressure valve 2 and the control valve 4, and then by starting the drive motor 371, the threaded rod 372 drives the moving block 6 to move along the outer surface of the side round rod 373, and then the moving block 6 drives the rack block 384 to move through the convex block 385 and the slide groove 386, so that the rack block 384 drives the magnet block 36 to move, and then the magnet block 36 drives the annular block 33 to move through the rotating iron block 35. At this time, since the annular block 33 contacts the outer surface of the first hose 31 and the inner surface of the second hose 32 respectively through the first annular rubber 7 and the second annular rubber 8, the annular block 33 can squeeze the leaked refrigerant back into the recovery tank 1 for recovery during the movement, and close the pressure valve 2 after recovery, thereby avoiding the refrigerant from leaking from the rupture caused by repeated squeezing of the first hose 31, causing environmental pollution.

[0045] After recovery, by starting the brake motor 381, the rotating rod 382 drives the gear block 383 and the rack block 384 to drive the magnet block 36 to reset, so that the rotating rod 382 drives the magnet block 36 to move to the bottom of the rotating iron block 35, and then the magnet block 36 attracts the rotating iron block 35 to rotate downward, releasing the squeezing effect on the first hose 31, and then by driving the motor 371, the threaded rod 372 drives the moving block 6 to move and reset along the outer surface of the side round rod 373, and then by opening the pressure valve 2 and the control valve 4, the refrigerant inside the refrigerator can be discharged into the recovery tank 1 through the pressure valve 2 and the second hose 32 and the control valve 4 in turn for recovery. Repeating this operation can recover the refrigerant inside the refrigerator.

[0046] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
