Description

Technical Field

[0001] This invention relates to the field of ice maker technology, specifically a carbon dioxide ice maker. Background Technology

[0002] Cascade carbon dioxide ice makers are the mainstream energy-saving and environmentally friendly ice-making equipment in the refrigeration field. By adopting a two-stage cascaded circulation architecture with high and low temperatures, the core consists of a high-temperature stage conventional refrigerant circuit and a low-temperature stage carbon dioxide refrigerant circuit. The two-stage system is coupled and heat exchanged through a cascade heat exchanger. The high-temperature stage circuit is responsible for condensing and cooling the low-temperature carbon dioxide, while the low-temperature carbon dioxide medium completes the low-temperature heat absorption and freezing process in the ice-making evaporator. Through the low-temperature heat exchange advantage of carbon dioxide environmentally friendly refrigerant, it effectively makes up for the shortcomings of traditional ice makers, such as high energy consumption, non-environmentally friendly refrigerant, and poor adaptability to low-temperature conditions, and has become the mainstream development direction in the industry.

[0003] Most current cascade carbon dioxide ice makers use a fixed-diameter feed pipe structure. The equipment operates in an intermittent ice discharge mode. During standby periods when ice making is not completed and feeding is not done, the fixed-diameter feed pipe is not easy to completely seal and isolate. External humid and hot air can continuously convect and exchange with the low-temperature cavity inside the equipment through the feed pipe. Because the ice-making temperature of carbon dioxide ice makers is extremely low, the inner wall of the feed pipe is in a state of ultra-low temperature for a long time. The intruding humid and hot water vapor will continuously condense, frost, and freeze on the pipe wall. After long-term operation, a frost bridge structure will be formed, gradually narrowing the cross-sectional area of ​​the feed channel. At the same time, the surface temperature of the ice blocks prepared at low temperature is extremely low, making it very easy to absorb water vapor and stick together. During the feeding process, faults such as ice jamming, pipe blockage, and material stagnation are prone to occur, requiring frequent shutdowns for manual cleaning of ice blockages and defrosting, which affects the continuous automated operation performance of the equipment.

[0004] To address the above problems, a carbon dioxide ice maker is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a carbon dioxide ice maker. By using this invention, the problems of the feeding pipe being in an ultra-low temperature state for a long time, causing the intruding hot water vapor to continuously condense, frost, and freeze on the pipe wall, and the ice blocks prepared at low temperature having extremely low surface temperature, making them very easy to absorb water vapor and stick together, and causing problems such as ice jamming, pipe blockage, and material stagnation during the feeding process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A carbon dioxide ice maker includes an ice maker body. The bottom of the ice maker body is connected to a dynamically adaptable feeding component for dynamically changing the pipe diameter. A drive component is provided on the outer wall of the dynamically adaptable feeding component. A rotating component is provided at one output end of the drive component. A dynamically pulling component is provided on one side of the rotating component for pulling and adjusting the pipe diameter of the dynamically adaptable feeding component. The dynamically pulling component is rotatably connected to the drive component. An elastic component is provided at the other output end of the drive component. A blocking component for blocking the feeding channel is provided at one end of the elastic component. An elastic pressing component for assisting in tightening the blocking component is provided inside the ice maker body.

[0007] Furthermore, the dynamic adaptive feeding assembly includes a feeding pipe connected to one side of the ice maker body, with several conical arc plates rotatably connected to the bottom of the feeding pipe, and several conical folding arc plates fixedly connected between the several conical arc plates. A rubber ring is provided inside the feeding pipe, and one side of the rubber ring is fixedly connected to the inner wall of the several conical arc plates and the several conical folding arc plates respectively.

[0008] Furthermore, the drive assembly includes a support ring fixedly connected to the outer wall of the feed pipe, and a dual-axis motor is mounted on the top of the support ring.

[0009] Furthermore, the rotating assembly includes a first rotating shaft fixedly connected to the lower output end of the dual-axis motor, and a gear is fixedly connected to the lower end of the first rotating shaft, with a gear ring meshing with the outer ring of the gear.

[0010] Furthermore, the dynamic pulling component includes a rotating ring rotatably connected to the outer wall of the support ring, a gear ring fixedly connected to the rotating ring, a plurality of connecting rods fixedly connected to the bottom of the rotating ring, and a guide ring fixedly connected to the lower end of the plurality of connecting rods. The guide ring has a plurality of arc-shaped grooves through which a rolling shaft is rotatably connected. A sliding rod is rotatably connected to one end of the rolling shaft. The sliding rods are fixedly connected to a plurality of conical arc plates respectively. A connecting ring is fixedly connected to the top of the support ring. A plurality of L-shaped connecting rods are fixedly connected to the outer ring of the connecting ring. A limit sleeve is fixedly connected to one end of the L-shaped connecting rod. The sliding rod is slidably connected to the limit sleeve.

[0011] Furthermore, the elastic component includes a second rotating shaft fixedly connected to the output end of the dual-axis motor, a first spring fixedly connected inside the second rotating shaft, and a first guide rod fixedly connected to the other end of the first spring, the first guide rod being slidably connected to the second rotating shaft.

[0012] Furthermore, a temporary storage slot is provided inside the main body of the ice maker.

[0013] Furthermore, the sealing assembly includes a sealing plate fixedly connected to one end of the first guide rod, the sealing plate being disposed in a temporary storage groove, and the outer ring of the top of the sealing plate being provided with an arc surface.

[0014] Furthermore, the elastic pressing component includes several second springs fixedly connected inside the ice maker body, and a second guide rod is fixedly connected to the other end of the second spring, with the second guide rod slidably connected to the ice maker body.

[0015] Furthermore, one end of the second guide rod is configured as an arc shape.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By dynamically adapting the feeding component and the pulling component, the feeding diameter can be gradually expanded during ice removal, reserving space for the ice blocks to move and avoiding problems such as ice jamming and pipe blockage caused by the sticking and squeezing of low-temperature ice blocks, thus enabling the equipment to operate continuously and stably.

[0017] By cooperating with the sealing component, the elastic component and the elastic pressing component, the feeding channel can be completely sealed in the standby state, blocking the convection of hot and cold air and preventing external moisture from condensing, accumulating frost and ice on the pipe wall.

[0018] By setting up a dual-axis motor in the drive assembly, the rotating assembly and the elastic assembly can be driven to work independently, realizing time-sharing linkage between diameter adjustment and channel blocking action, simplifying the overall drive structure and ensuring precise synchronization of the mechanism's action sequence.

[0019] The combination of the conical folded arc plate and the rubber ring can fill the structural gaps throughout the entire process of pipe diameter expansion and contraction, maintain the continuous sealing state of the inner wall, and at the same time have good resistance to low temperature deformation.

[0020] Through the cooperation between the guide ring, slide bar and limit sleeve, the movement of the conical arc plate can be precisely guided and limited, making the variable diameter transmission run more smoothly, avoiding component misalignment and preventing the mechanism from jamming.

[0021] By setting the arc surface of the sealing plate and the second guide rod at the arc end, the frictional resistance when the two are in contact during operation can be reduced, making the opening and closing action of the sealing component more flexible and smooth, reducing the wear of components, and extending the overall service life of the mechanism.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To address the technical problems arising from the long-term ultra-low temperature condition of the inner wall of the feed pipe 21, where intruding humid hot water vapor continuously condenses, frosts, and freezes on the pipe wall, and where the surface temperature of the ice blocks prepared at low temperatures is extremely low, making them highly susceptible to absorbing moisture and sticking together, leading to malfunctions such as ice jams, pipe blockages, and material stagnation during the feeding process, such as... Figures 1-7 As shown, the following preferred technical solutions are provided: A carbon dioxide ice maker includes an ice maker body 1, which is a cascade carbon dioxide ice maker capable of performing low-temperature ice making through a cascade heat exchange circuit. A controller is installed on one side of the ice maker body 1 to control various electrical components. The controller is existing technology and is not shown in the figure. A dynamic adaptive feeding component 2 for dynamically changing the pipe diameter is connected to the bottom of the ice maker body 1. A drive component 3 is provided on the outer wall of the dynamic adaptive feeding component 2. A rotating component 4 is provided at one output end of the drive component 3. A dynamic pulling component 5 for pulling and adjusting the pipe diameter of the dynamic adaptive feeding component 2 is provided on one side of the rotating component 4. The dynamic pulling component 5 is rotatably connected to the drive component 3. An elastic component 6 is provided at the other output end of the drive component 3. A blocking component 7 for blocking the feeding channel is provided at one end of the elastic component 6.

[0026] During use, the controller enables the ice maker body 1 to complete the ice-making process of water injection and freezing. After ice making is completed, the controller enables another output end of the drive component 3 to drive the elastic component 6 and the blocking component 7 to move counterclockwise in sync. This causes the blocking component 7 to unblock the dynamic adaptive feeding component 2, and then the ice discharge operation is performed. At the same time, the controller enables one output end of the drive component 3 to drive the rotating component 4 to rotate counterclockwise, so that the dynamic pulling component 5 slowly pulls the dynamic adaptive feeding component 2, which can gradually expand the feeding diameter and leave room for the ice blocks to move. Compared with the fixed diameter ice outlet pipe in the existing technology, it can prevent the ice blocks from squeezing and sticking together and blocking the channel.

[0027] The ice maker body 1 is equipped with an elastic pressing component 8 for assisting in tightening and sealing the component 7.

[0028] After the ice removal and material feeding are completed, the controller causes one of the outputs of the drive component 3 to rotate the rotating component 4 clockwise, which causes the dynamic pulling component 5 to slowly pull the dynamic adaptive feeding component 2 to reset, thus restoring the minimum flow path for the next ice-making operation. At the same time, the controller causes the other output of the drive component 3 to move the elastic component 6 and the sealing component 7 clockwise synchronously. Meanwhile, the sealing component 7 will squeeze the elastic pressing component 8, and the thrust of the elastic pressing component 8 will push the sealing component 7 to fit tightly against the dynamic adaptive feeding component 2, and simultaneously compress the elastic component 6. This can achieve complete sealing of the feeding channel, block the convection of hot and cold air, and reduce the loss of cold energy during non-ice removal periods.

[0029] The dynamically adaptable feeding assembly 2 includes a feeding pipe 21 connected to one side of the ice maker body 1. Several conical arc plates 22 are rotatably connected to the bottom of the feeding pipe 21. Several conical folding arc plates 23 are fixedly connected between the conical arc plates 22. The conical folding arc plates 23 are made of food-grade low-temperature resistant silicone rubber and can maintain a complete sealing surface under tension and compression. A rubber ring 24 is provided inside the feeding pipe 21. One side of the rubber ring 24 is fixedly connected to the inner wall of the conical arc plates 22 and the conical folding arc plates 23 respectively. The rubber ring 24 can fill the splicing gap between the conical arc plates 22 and the conical folding arc plates 23 to form a continuous and smooth inner wall surface. At the same time, it expands and contracts synchronously with the flow diameter adjustment process to maintain a gapless sealing state throughout the process.

[0030] The drive assembly 3 includes a support ring 31 fixedly connected to the outer wall of the feed tube 21. A dual-axis motor 32 is mounted on the top of the support ring 31. The dual-axis motor 32 is a stepper motor with two output shafts that can independently control the rotation of the two output ends.

[0031] The rotating assembly 4 includes a first rotating shaft 41 fixedly connected to the lower output end of the dual-axis motor 32, and a gear 42 is fixedly connected to the lower end of the first rotating shaft 41. A gear ring 43 is meshed with the outer ring of the gear 42.

[0032] The dynamic pulling component 5 includes a rotating ring 51 rotatably connected to the outer wall of the support ring 31, a gear ring 43 fixedly connected to the rotating ring 51, a number of connecting rods 52 fixedly connected to the bottom of the rotating ring 51, and a guide ring 53 fixedly connected to the lower end of the connecting rods 52. The guide ring 53 has a number of arc-shaped grooves 54 through it. Rolling shafts 55 are rolledly connected in each of the arc-shaped grooves 54. A sliding rod 56 is rotatably connected to one end of the rolling shaft 55. The sliding rods 56 are fixedly connected to a number of conical arc plates 22 respectively. A connecting ring 57 is fixedly connected to the top of the support ring 31. A number of L-shaped connecting rods 58 are fixedly connected to the outer ring of the connecting ring 57. A limit sleeve 59 is fixedly connected to one end of the L-shaped connecting rod 58. The sliding rod 56 is slidably connected to the limit sleeve 59.

[0033] The elastic component 6 includes a second rotating shaft 61 fixedly connected to the output end of the dual-axis motor 32. A first spring 62 is fixedly connected inside the second rotating shaft 61, and a first guide rod 63 is fixedly connected to the other end of the first spring 62. The first guide rod 63 is slidably connected to the second rotating shaft 61.

[0034] The ice maker body 1 has a temporary storage tank 11 inside.

[0035] The sealing assembly 7 includes a sealing plate 71 fixedly connected to one end of the first guide rod 63. The sealing plate 71 is disposed in the temporary storage groove 11, and the top outer ring of the sealing plate 71 is provided with an arc surface 72.

[0036] During use, the controller enables the ice maker body 1 to complete the ice-making process of water injection and freezing. After ice making is completed, the controller enables the dual-axis motor 32 to drive the second rotating shaft 61, the first guide rod 63 and the sealing plate 71 to move counterclockwise synchronously, so that the sealing plate 71 can unblock the feeding pipe 21, and then the ice discharge operation is performed. At the same time, the controller enables the first rotating shaft 41 driven by the dual-axis motor 32 to rotate with the gear 42. Through the meshing of the gear 42 and the gear ring 43, the rotating ring 51, the connecting rod 52 and the guide ring 53 are driven to rotate counterclockwise synchronously. Through the guidance of the arc groove 54, the rolling shaft 55 rolls in the arc groove 54, pulling the slide rod 56 to slide in the limiting sleeve 59. The slide rod 56 slowly pulls the conical folding arc plate 23, which can gradually expand the feeding diameter and leave room for the ice blocks to move. Compared with the fixed diameter ice outlet pipe in the prior art, it can prevent the ice blocks from squeezing and sticking together and blocking the channel.

[0037] To address the technical problem of gaps easily forming during sealing, such as Figure 3 and Figure 4As shown, the following preferred technical solutions are provided: The elastic pressing component 8 includes several second springs 81 fixedly connected inside the ice maker body 1. The elastic force of the second springs 81 is greater than that of the first springs 62, which can provide a continuous and stable downward pressing force to ensure that the sealing plate 71 is tightly attached to the end face of the feed tube 21. The other end of the second springs 81 is fixedly connected to a second guide rod 82, which is slidably connected to the ice maker body 1.

[0038] One end of the second guide rod 82 is set to be arc-shaped, which can reduce the frictional resistance when it comes into contact with the sealing plate 71 and ensure that the sealing plate 71 rotates smoothly.

[0039] After the ice discharge is completed, the controller causes the first rotating shaft 41 driven by the dual-axis motor 32 to rotate with the gear 42. Through the meshing of the gear 42 and the gear ring 43, the rotating ring 51, the connecting rod 52, and the guide ring 53 rotate synchronously clockwise. Guided by the arc-shaped groove 54, the rolling shaft 55 rolls within the arc-shaped groove 54, pulling the slide rod 56 to slide within the limit sleeve 59. This causes the slide rod 56 to slowly push the conical folding arc plate 23 to reset, pre-restoring the minimum diameter state for one round of ice making. At the same time, the controller... The device enables the dual-axis motor 32 to drive the second rotating shaft 61, the first guide rod 63, and the sealing plate 71 to move clockwise synchronously. This causes the sealing plate 71 to block the feeding pipe 21. At the same time, the sealing plate 71 will squeeze the second guide rod 82 and simultaneously squeeze the second spring 81. The thrust of the second spring 81 pushes the sealing plate 71 to fit tightly against the dynamically adaptable feeding assembly 2, and simultaneously drives the first guide rod 63 to compress the first spring 62. This can achieve complete sealing of the feeding channel, block the convection of hot and cold air, and reduce the loss of cold energy during non-ice removal periods.
