Description

Technical Field

[0001] The present invention relates to the technical field of overload protection for air-conditioning compressors, and specifically to an air-conditioning compressor with overload protection. Background Art

[0002] An air-conditioning compressor plays a role in compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The air-conditioning compressor is generally installed in the outdoor unit. The air-conditioning compressor extracts the refrigerant from the low-pressure area, compresses it, and then sends it to the high-pressure area for cooling and condensation. Heat is dissipated into the air through the radiator fins, and the refrigerant also changes from a gaseous state to a liquid state, with the pressure increasing.

[0003] An existing air-conditioning compressor with overload protection has a relatively simple structure. At present, most of the cooling water used by air-conditioning compressors during operation is not recycled, which greatly increases the water resource consumption of the equipment. At the same time, most air-conditioning compressors will only have their power supply cut off after overload. If the temperature of the air-conditioning compressor itself is too high, spontaneous combustion may still occur after power-off.

[0004] Therefore, the present invention provides an air-conditioning compressor with overload protection to solve the above problems. Summary of the Invention

Detailed Description of the Preferred Embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0027] Please refer to Figure 1 - Figure 4 , an air conditioner compressor with overload protection, including a support leg 1. A protection bin 2 is fixedly connected to the top of the support leg 1. A cooling mechanism 3 is fixedly connected to the inner wall of the protection bin 2. An air conditioner compressor 6 is slidably connected to the inner wall of the cooling mechanism 3. A protection mechanism 5 is fixedly connected to one side of the protection bin 2. A spraying mechanism 4 is fixedly connected to the other side of the protection bin 2. One side of the protection mechanism 5 is slidably connected to the side wall of the air conditioner compressor 6. The inner wall of the spraying mechanism 4 is rotatably connected to the side wall of the cooling mechanism 3;

[0028] The cooling mechanism 3 includes a cooling box 33. The side wall of the cooling box 33 is fixedly connected to the inner wall of the protection bin 2. A water inlet pipe 31 communicates with the top of the cooling box 33. An electromagnetic valve 32 is provided on the water inlet pipe 31. A transmission shaft 34 is rotatably connected to the inner wall of the cooling box 33. Stirring blades 35 are fixedly connected to the side wall of the transmission shaft 34. One end of the transmission shaft 34 is fixedly connected to a driving motor 30. A water outlet pipe 36 communicates with the bottom of the cooling box 33. A connecting cross bar 37 is fixedly connected to the inner wall of the water outlet pipe 36. A telescopic rod 38 is fixedly connected to the bottom of the connecting cross bar 37. A first temperature-sensitive spring 39 is fixedly connected to the bottom of the connecting cross bar 37. A sliding sealing plate 391 is fixedly connected to the bottom of the first temperature-sensitive spring 39. The side wall of the sliding sealing plate 391 is slidably connected to the inner wall of the water outlet pipe 36. The bottom of the telescopic rod 38 is fixedly connected to the top of the sliding sealing plate 391. The water outlet pipe 36 penetrates through the protection bin 2, and the water inlet pipe 31 penetrates through the protection bin 2;

[0029] It should be noted that when the air conditioner compressor 6 works inside the protection bin 2, the electromagnetic valve 32 is opened, and the staff inputs cooling water into the cooling box 33 through the water inlet pipe 31, and starts the driving motor 30. The driving motor 30 drives the stirring blades 35 to rotate through the transmission shaft 34 to stir the cooling water inside the cooling box 33, so that the cooling of the air conditioner compressor 6 is more uniform. When the temperature of the cooling water inside the cooling box 33 reaches 40 degrees, the telescopic rod 38 drives the sliding sealing plate 391 to press down, and the sliding sealing plate 391 moves away from the inside of the water outlet pipe 36, and the cooling water inside the cooling box 33 is discharged from the inside of the water outlet pipe 36. When the temperature inside the cooling box 33 drops below 40 degrees after new cooling water enters the cooling box 33 through the water inlet pipe 31, the first temperature-sensitive spring 39 drives the sliding sealing plate 391 to rise and reset. The setting of the telescopic rod 38 prevents the sliding sealing plate 391 from hitting around and limits its position in the vertical direction. Embodiment 2

[0030] Please refer to Figure 5 - Figure 6, on the basis of Embodiment 1, this embodiment provides a technical solution: The spraying mechanism 4 includes a water delivery pipe 40. One end of the water delivery pipe 40 is communicated with the bottom of the water outlet pipe 36, and the other end of the water delivery pipe 40 is communicated with a water storage bin 41. The top of the water storage bin 41 is communicated with a first connecting water pipe 42. One end of the first connecting water pipe 42 is communicated with a water pump 43. One end of the water pump 43 is communicated with a second connecting water pipe 44. The bottom of the second connecting water pipe 44 is communicated with a water spraying disc 45. The bottom of the water spraying disc 45 is communicated with atomizing nozzles 46. The bottom of the water pump 43 is fixedly connected to the top of the protection bin 2. One side of the water storage bin 41 is fixedly connected to the side wall of the protection bin 2. The other side of the water storage bin 41 is fixedly connected to one side of the driving motor 30;

[0031] It should be noted that when the cooling water is discharged from the inside of the water outlet pipe 36, it enters the inside of the water storage bin 41 through the water delivery pipe 40 and is stored therein. When the temperature of the air-conditioning compressor 6 is too high and it is taken out by the sliding vertical plate 50, the water pump 43 is started. The water pump 43 inputs the cooling water inside the water storage bin 41 into the water spraying disc 45 through the first connecting water pipe 42 and the second connecting water pipe 44. The water spraying disc 45 evenly sprays the cooling water inside onto the surface of the air-conditioning compressor 6 through the atomizing nozzles 46, forms a water film on its surface and cools it down, preventing the air-conditioning compressor 6 from being damaged due to excessive temperature and prolonging the service life of the air-conditioning compressor 6. Embodiment 3

[0032] Please refer to Figure 7 - Figure 9 , on the basis of Embodiment 1, this embodiment provides a technical solution: The protection mechanism 5 includes a second telescopic rod 51. One end of the second telescopic rod 51 is fixedly connected to one side of the protection bin 2. A second temperature-sensitive spring 511 is fixedly connected to one side of the protection bin 2. One end of the second telescopic rod 51 is fixedly connected to a sliding vertical plate 50. A storage groove 52 is formed inside the sliding vertical plate 50. An electromagnet 57 is fixedly connected to one side of the sliding vertical plate 50. A pressing rod 53 is fixedly connected to one side of the protection bin 2. A damping cylinder 54 is slidably connected to the side wall of the pressing rod 53. A fixed ring 55 is fixedly connected to the inner wall of the damping cylinder 54. A rubber pad 56 is fixedly connected to one side of the damping cylinder 54. The side wall of the damping cylinder 54 is slidably connected to the inner wall of the storage groove 52. One end of the second temperature-sensitive spring 511 is fixedly connected to one side of the sliding vertical plate 50;

[0033] It should be noted that when the temperature of the air-conditioning compressor 6 is higher than 85 degrees during operation, the electromagnet 57 is activated. The electromagnet 57 adsorbs and fixes the air-conditioning compressor 6. The second temperature-sensitive spring 511 drives the storage groove 52 to move away from the protection bin 2. When the storage groove 52 moves, it drives the air-conditioning compressor 6 away from the inside of the protection bin 2 through the electromagnet 57, providing overload protection for the air-conditioning compressor 6 to prevent it from being damaged due to excessive temperature. After the air-conditioning compressor 6 is repaired and cooled down, the second temperature-sensitive spring 511 drives the air-conditioning compressor 6 to reset through the sliding vertical plate 50 and the electromagnet 57. When the sliding vertical plate 50 moves to the surface of the protection bin 2, the rubber pad 56 enters the inside of the storage groove 52 to complete primary shock absorption. The sliding vertical plate 50 drives the damping cylinder 54 close to the protection bin 2 through the storage groove 52 and the rubber pad 56. The extrusion rod 53 squeezes the damping liquid inside the damping cylinder 54 through the fixed ring 55 and enters the other side inside the damping cylinder 54, reducing the speed of the sliding vertical plate 50 approaching the surface of the protection bin 2 to prevent the sliding vertical plate 50 from hitting the surface of the protection bin 2 too fast and causing damage to the device.

[0034] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] During operation, when the air-conditioning compressor 6 is working inside the protection bin 2, the solenoid valve 32 is opened. The staff inputs cooling water into the cooling tank 33 through the water inlet pipe 31, and the drive motor 30 is started. The drive motor 30 drives the stirring blade 35 to rotate through the transmission shaft 34 to stir the cooling water inside the cooling tank 33, making the cooling of the air-conditioning compressor 6 more uniform. When the temperature of the cooling water inside the cooling tank 33 reaches 40 degrees, the telescopic rod 38 drives the sliding sealing plate 391 to press down. The sliding sealing plate 391 moves away from the inside of the water outlet pipe 36, and the cooling water inside the cooling tank 33 is discharged from the inside of the water outlet pipe 36. When the temperature inside the cooling tank 33 drops below 40 degrees after new cooling water enters the cooling tank 33 through the water inlet pipe 31, the first temperature-sensitive spring 39 drives the sliding sealing plate 391 to rise and reset. The setting of the telescopic rod 38 prevents the sliding sealing plate 391 from hitting around and provides vertical direction limit for it.

[0036] When the temperature of the air-conditioning compressor 6 is higher than 85 degrees during operation, the electromagnet 57 is activated. The electromagnet 57 adsorbs and fixes the air-conditioning compressor 6. The second temperature-sensitive spring 511 drives the storage groove 52 to move away from the protection bin 2. When the storage groove 52 moves, it drives the air-conditioning compressor 6 away from the inside of the protection bin 2 through the electromagnet 57, providing overload protection for the air-conditioning compressor 6 to prevent it from being damaged due to excessive temperature. After the air-conditioning compressor 6 is repaired and cooled down, the second temperature-sensitive spring 511 drives the air-conditioning compressor 6 to reset through the sliding vertical plate 50 and the electromagnet 57. When the sliding vertical plate 50 moves to the surface of the protection bin 2, the rubber pad 56 enters the inside of the storage groove 52 to complete primary shock absorption. The sliding vertical plate 50 drives the damping cylinder 54 close to the protection bin 2 through the storage groove 52 and the rubber pad 56. The extrusion rod 53 squeezes the damping liquid inside the damping cylinder 54 through the fixed ring 55 and enters the other side of the inside of the damping cylinder 54, reducing the speed of the sliding vertical plate 50 approaching the surface of the protection bin 2 to prevent the sliding vertical plate 50 from hitting the surface of the protection bin 2 too fast and causing damage to the device;

[0037] When the cooling water is discharged from the inside of the water outlet pipe 36, it enters the inside of the water storage bin 41 through the water delivery pipe 40 and is stored there. When the temperature of the air-conditioning compressor 6 is too high and it is taken out by the sliding vertical plate 50, the water pump 43 is started. The water pump 43 inputs the cooling water inside the water storage bin 41 into the inside of the water spraying disc 45 through the first connecting water pipe 42 and the second connecting water pipe 44. The water spraying disc 45 evenly sprays the cooling water inside it through the atomizing nozzles 46 onto the surface of the air-conditioning compressor 6, forming a water film on its surface and cooling it down, preventing the air-conditioning compressor 6 from being damaged due to excessive temperature and prolonging the service life of the air-conditioning compressor 6.
