Description

Technical Field

[0001] The invention belongs to the technical field of defrosting mechanisms, and specifically relates to a defrosting mechanism for air energy equipment. Background Art

[0002] The defrost mechanism of air energy equipment refers to a device or system designed to remove frost on the evaporator. In the air energy heat pump system, when the ambient temperature is low, frost may form on the evaporator surface, which will affect the efficiency and operation of the heat pump. Therefore, a mechanism is needed to remove the frost regularly or as needed to ensure the normal and efficient operation of the equipment.

[0003] Frost on existing evaporators is usually concentrated on the front surface of the fins (i.e., the side facing the fluid). Under low ambient temperatures, when water vapor in the air condenses into frost when it is cold, it will gradually accumulate on the surface of the evaporator to form a layer of ice. When the frost has been formed for a long time or the temperature is low, the frost accumulated on the surface of the evaporator may indeed harden. When the scraper is used to remove the frost, scraping it away when it encounters a harder ice layer will cause damage to the scraper and deformation of the evaporator fins.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 8 As shown, the present invention provides a technical solution: a defrosting mechanism for air energy equipment, including an evaporator 1, fixed columns 2 are arranged on both sides of the evaporator 1, the main part of the evaporator 1 is composed of a plurality of fins and a copper tube, a plurality of inner notches 3 are opened on the outer sides of the two fixed columns 2, the number and width of the inner notches 3 are the same as the gap between every two fins of the evaporator 1 and correspond one to one, a frost scraping assembly is arranged on one side of the fixed column 2, the frost scraping assembly is used to scrape off the frost on the surface of the fixed column 2, an ice breaking assembly is arranged on one side of the frost scraping assembly, the ice breaking assembly is used to break the ice layer on the surface of the fixed column 2 and the ice layer formed between the fin gap, and a fan assembly is arranged on the other side of the fixed column 2, the fan assembly is used to blow out the crushed ice in the gap between every two fins.

[0023] During operation: Frost on existing evaporators is usually concentrated on the front surface of the fins, i.e., the side facing the fluid. Under low ambient temperatures, when water vapor in the air condenses into frost when it is cold, it will gradually accumulate on the surface of the evaporator to form a layer of ice. When the frost has been formed for a long time or the temperature is low, the frost accumulated on the surface of the evaporator may indeed harden. When the scraper is used to remove the frost, scraping it away when it encounters a harder ice layer will cause damage to the scraper and deformation of the evaporator fins. Through the implementation example of this scheme, when it is used specifically, the entire defrosting mechanism is first installed inside the frame of the air energy equipment. Under low ambient temperatures, frost will form on the front surface of the evaporator 1 inside the air energy equipment, i.e., the side facing the fluid. , and then by starting the defrost scraper assembly, the defrost scraper assembly will scrape off the frost on the fins of the evaporator 1, and during the movement of the defrost scraper assembly, it will drive the ice-breaking assembly to move, and the ice-breaking assembly can break the hard ice layer covering the fins on the front surface of the evaporator 1 and the ice layer formed between the fin gaps. The defrost scraper assembly can effectively scrape off the frost and ice accumulated on the surface of the evaporator. The movement of the ice-breaking assembly can help break and remove the frost and ice layer, especially the hard ice layer formed between or on the surface of the fins, which helps prevent the ice layer from blocking the air flow channel on the surface of the evaporator, thereby ensuring the normal operation of the air energy equipment, and during the movement of the ice-breaking assembly, it will also drive the fan assembly to move, and blow out the broken ice flakes remaining between the fin gaps after the breaking is completed.

[0024] like Figures 3 to 5As shown, the frost scraping assembly includes a scraper 4, which is attached to the fins of the evaporator 1, and the top and bottom of the scraper 4 are slidably connected with clamping members 5, the top surfaces of the two clamping members 5 are fixedly connected with fixing rods 6, one ends of the two fixing rods 6 are fixedly connected with connecting rods 7, one side of the two connecting rods 7 is fixedly connected with sliding blocks 8, and a fixing seat 9 is symmetrically fixedly connected between the two fixing columns 2, the inner walls of the two fixing seats 9 are rotatably connected with threaded rods 10 respectively, the inner walls of the two fixing seats 9 are rotatably connected with the outer walls of the two threaded rods 10 respectively, the inner walls of the two sliding blocks 8 are threadedly connected with the outer walls of the two threaded rods 10 respectively, and the sides of the two fixing seats 9 are provided with sliding grooves 11, which are slidably connected to the outer walls of the connecting rods 7 and adapt to each other, and a driving assembly is provided on one side of the fixing seat 9, and the driving assembly is used to drive the two threaded rods 10 to rotate simultaneously.

[0025] When working: start the driving component, the driving component will drive the two threaded rods 10 to rotate. When the two threaded rods 10 rotate, the slider 8 will slide inside the fixed seat 9. When the slider 8 slides, the scraper 4 will slide through the connecting rod 7 and the fixed rod 6. During the sliding process, the scraper 4 will fit the fin surface of the evaporator 1 to scrape off the frost flakes accumulated on the surface of the evaporator 1. The threaded rod 10 is rotated and the slider 8 slides inside the fixed seat 9, so that the scraper 4 can scrape off the frost flakes stably and efficiently.

[0026] like Figure 3 to Figure 4 As shown, the driving assembly includes a motor 16, which is fixedly installed on one side of the fixed column 2. The output shaft of the motor 16 is fixedly connected to the driving shaft 14. The outer wall of the driving shaft 14 is transmission-connected to a transmission belt 13. The inner sides of both ends of the transmission belt 13 are transmission-connected to transmission rings 12. The two transmission rings 12 are fixedly connected to one side of the two threaded rods 10 respectively.

[0027] During operation: start the motor 16, and its output shaft will drive the driving shaft 14 to rotate. When the driving shaft 14 rotates, it will drive the two driving rings 12 to rotate through the transmission belt 13. When the two driving rings 12 rotate, they will drive the two threaded rods 10 to rotate at the same time, thereby achieving the effect of driving the two sliders 8 to move in the fixed seat 9, so that the scraper 4 can scrape off the frost flakes.

[0028] like Figure 6 to Figure 7 As shown, the inner wall of the scraper 4 is symmetrically fixedly connected with a slide rod 17, and the bottoms of the two clamping members 5 are symmetrically fixedly connected with a side slide groove seat 18, and the two slide rods 17 are respectively slidably connected to the inner walls of the side slide groove seat 18 and are adapted to each other.

[0029] During operation: When the scraper 4 is scraping frost, when it touches the harder ice layer covering the fins, due to the sliding connection between the scraper 4 and the clamping member 5, the scraper 4 will slide along the surface of the ice layer when encountering the harder ice layer, and scrape off the frost flakes on the surface of the ice layer, and the ice layer is broken by the ice-breaking assembly. When the scraper 4 slides along the ice layer, since the ice layer has a certain thickness, the scraper 4 will slide in the inner wall of the inner slide rod 19 through the slide rod 17, so that the scraper 4 can maintain a fit with the raised ice layer and move to scrape the frost. When encountering the ice layer, the scraper 4 will not forcibly scrape it off, but will scrape the frost along the surface of the ice layer, waiting for the ice-breaking assembly to process the ice layer.

[0030] like Figure 7 As shown, one side of the slide rod 17 is symmetrically fixedly connected with an inner slide rod 19, and the two inner slide rods 19 are respectively located inside the side slide groove seat 18.

[0031] During operation: Since the thickness of the ice layer is uneven, in order to keep the scraper 4 able to always scrape frost along the surface of the ice layer, the inner slide bar 19 and the return spring 20 are provided so that the slide bar 17 can be quickly reset after sliding on the inner wall of the side slide groove seat 18, so that the scraper 4 can always slide along the surface of the ice layer.

[0032] like Figures 5 and 6 As shown, the ice-breaking assembly includes a rotating rod 24, the outer walls of the two clamping members 5 are symmetrically fixedly connected with connecting sleeves 22, the two connecting sleeves 22 are rotatably connected to the inner wall of the rotating rod 24, the outer wall of the rotating rod 24 is fixedly connected with a plurality of ice-breaking cones 25, the ice-breaking cones 25 are all located in the gaps between the inner notches 3 and correspond one to one, the top of the rotating rod 24 is fixedly connected with a transmission ring 23, the top of the transmission ring 23 is provided with a rotating assembly, and the rotating assembly is used to drive the transmission ring 23 to rotate.

[0033] During operation: When the scraper 4 moves to scrape the frost, the connecting kit 22 will drive the rotating rod 24 and the ice-breaking cone 25 to move. When the rotating rod 24 and the ice-breaking cone 25 move, the rotating assembly can make the transmission ring 23 always rotate during the movement, so that the rotating rod 24 drives several ice-breaking cones 25 to rotate, and the ice layer between the outer surface of the fin of the evaporator 1 and the fin gap is broken. The ice layer will hinder the heat transfer between the fin and the surrounding air or fluid. By breaking the ice layer, the heat transfer capacity of the evaporator surface can be restored, thereby improving the overall heat transfer efficiency.

[0034] like Figures 4 to 5As shown, the rotating assembly includes a driving gear 26, which is fixedly mounted on the outer wall of one of the threaded rods 10, and the teeth of the driving gear 26 are meshed with a driven gear 27, the inner sides of the two fixed columns 2 are fixedly connected with a clamping shaft 29, the inner wall of the clamping shaft 29 is rotatably connected with a driving ring 28, the driven gear 27 is fixedly connected to one of the driving rings 28, a transmission belt 230 is transmission-connected between the two driving rings 28, and the outer wall of the transmission ring 23 is transmission-connected to the inner wall of the transmission belt 230.

[0035] During operation: when the threaded rod 10 rotates and drives the scraper 4 to move through the slider 8, the ice-breaking assembly will move with the scraper 4, and during the movement, the threaded rod 10 will drive the driving gear 26 to rotate, the driving gear 26 will drive the driven gear 1 27 to rotate, the driven gear 1 27 will drive the driving ring 1 28 to rotate, the clamping shaft 29 fixes the position of the driving ring 1 28, and when the driving ring 1 28 rotates, the transmission belt 2 30 will transmit, and during the transmission process of the transmission belt 2 30, it will drive the transmission ring 23 to rotate, so that the ice-breaking cone 25 can break the ice layer, and during the movement of the transmission ring 23, its outer wall always maintains a transmission relationship with the inner wall of the transmission belt 2 30, so that the entire ice-breaking assembly can rotate during the movement, thereby achieving the effect of breaking.

[0036] like Figure 2 and Figure 8 As shown, the fan assembly includes multiple groups of fan blades 33, and the fan blades 33 are all located on the back of the evaporator 1. The shafts of the fan blades 33 are rotatably connected to the mounting platform 31, and the mounting platform 31 is fixedly installed on one side of the fixed column 2. A transmission assembly is provided on one side of the fan blades 33, and the transmission assembly is used to drive the fan blades 33 to rotate.

[0037] During operation: When the starting motor 16 drives the defrosting assembly to move, it will drive multiple sets of fan blades 33 to rotate through the transmission assembly. When the ice-breaking assembly processes the ice layer on the surface and gap of the evaporator 1 fins, the broken ice will remain in the gaps of the fins. When the fan blades 33 rotate, the ice in the gaps can be effectively blown out to avoid affecting the operation of the fins.

[0038] like Figure 2 and Figure 8 As shown, the transmission assembly includes a driven gear 2 37, one side of the driven gear 2 37 is fixedly connected to a rotating rod 36, one end of the rotating rod 36 is fixedly connected to a driving ring 2 35, the shafts of the multiple groups of fan blades 33 are all fixedly connected to a transmission ring 3 32, and a transmission belt 3 34 is transmission-connected between the driving ring 2 35 and the outer walls of the multiple transmission rings 3 32.

[0039] During operation: when the driven gear 2 37 rotates, the driving ring 2 35 will be driven to rotate through the rotating rod 36. When the driving ring 2 35 rotates, the transmission belt 3 34 will drive multiple transmission rings 3 32 to rotate, thereby achieving the effect of driving the fan blades 33 to rotate, thereby achieving the purpose of processing ice chips in the gaps.

[0040] like Figure 2 and Figure 8 As shown, the teeth of the driven gear 2 37 mesh with the driving gear 15, and the driving gear 15 is fixedly mounted on the outer wall of the output shaft of the motor 16. The outer wall of one of the fixed columns 2 is fixedly connected to a clamping rod 38, and the inner wall of the clamping rod 38 is rotatably connected to the outer wall of the rotating rod 36.

[0041] During operation: when the starting motor 16 drives the defrost scraper assembly and the ice breaking assembly to move, the driven gear 1 15 will drive the driven gear 2 37 to rotate. When the driven gear 2 37 rotates, it will drive multiple sets of fan blades 33 to rotate, thereby completing the function of blowing out the ice in the gaps between the fins, and the position of the driven gear 2 37 and the drive ring 2 35 is fixed by the clamping rod 38.

[0042] Working process: First, install the entire defrost mechanism inside the air energy equipment frame. Under low ambient temperature, frost will form on the front surface of the evaporator 1 inside the air energy equipment, that is, the side facing the fluid. Start the motor 16, and its output shaft will drive the drive shaft 14 to rotate. When the drive shaft 14 rotates, it will drive the two transmission rings 12 to rotate through the transmission belt 13. When the two transmission rings 12 rotate, they will drive the two threaded rods 10 to rotate at the same time. When the two threaded rods 10 rotate, they will drive the slider 8 to slide inside the fixed seat 9. When the slider 8 slides, it will drive the scraper 4 to slide through the connecting rod 7 and the fixed rod 6. During the sliding process, the scraper 4 will fit the fin surface of the evaporator 1 to scrape off the frost flakes accumulated on the surface of the evaporator 1.

[0043] Secondly, when the scraper 4 is scraping frost, when it touches the harder ice layer covering the fin, due to the sliding connection between the scraper 4 and the clamping member 5, the scraper 4 will slide along the surface of the ice layer when encountering the harder ice layer, and scrape off the frost flakes on the surface of the ice layer, and the ice layer will be broken by the ice breaking assembly. When the scraper 4 slides along the ice layer, since the ice layer has a certain thickness, the scraper 4 will slide in the inner wall of the inner slide bar 19 through the slide bar 17, so that the scraper 4 can contact the protruding ice layer Maintain the fitted state and move to scrape the frost. When encountering an ice layer, the scraper 4 will not forcibly scrape away, but scrape the frost along the surface of the ice layer, waiting for the ice-breaking assembly to process the ice layer. Since the thickness of the ice layer is uneven, in order to keep the scraper 4 able to always scrape the frost along the surface of the ice layer, the inner sliding rod 19 and the reset spring 20 are set, so that the sliding rod 17 can be quickly reset after sliding on the inner wall of the side sliding groove seat 18, so that the scraper 4 can always slide along the surface of the ice layer.

[0044] When the scraper 4 moves to scrape frost, the connecting kit 22 drives the rotating rod 24 and the ice-breaking cone 25 to move. When the rotating rod 24 and the ice-breaking cone 25 move, the threaded rod 10 drives the driving gear 26 to rotate, and the driving gear 26 drives the driven gear 1 27 to rotate. The driven gear 1 27 drives the driving ring 1 28 to rotate. The clamping shaft 29 fixes the position of the driving ring 1 28. When the driving ring 1 28 rotates, the transmission belt 2 30 transmits the transmission. During the transmission process of the transmission belt 2 30, the transmission ring 23 is driven to rotate, so that the ice-breaking cone 25 can break the ice layer. The transmission ring 23 can always rotate during the movement, so that the rotating rod 24 drives several ice-breaking cones 25 to rotate, and the ice layer between the outer surface of the fin of the evaporator 1 and the fin gap is broken. The ice layer will hinder the heat transfer between the fin and the surrounding air or fluid. By breaking the ice layer, the heat transfer capacity of the evaporator surface can be restored, thereby improving the overall heat transfer efficiency.

[0045] Finally, when the starting motor 16 drives the defrost scraper assembly and the ice breaking assembly to move, it will drive the driven gear 2 37 to rotate through the driving gear 1 15, and the driven gear 2 37 will drive the driving ring 2 35 to rotate through the rotating rod 36. When the driving ring 2 35 rotates, it will drive multiple transmission rings 3 32 to rotate through the transmission belt 3 34, and 32 will drive multiple groups of fan blades 33 to rotate. When the fan blades 33 rotate, they can effectively blow out the ice in the gap to avoid affecting the operation of the fins.
