[0004] Chinese Patent 202221376072.2 discloses a continuous extrusion ice-making mechanism, including an ice-making shell, a spiral reamer, and an evaporator tube. The upper end of the ice-making shell is provided with several ice outlets. The evaporator tube is coiled around the outer wall of the ice-making shell to provide the cooling capacity required for ice making. The spiral reamer is disposed inside the ice-making shell and can be driven to rotate by a motor to extrude ice from the ice outlets inside the ice-making shell. The ice-making shell includes a cylinder, a plug, and a base. The cylinder is made by cutting a metal round tube and machining external threads on its lower end. The base is threadedly connected to the lower end of the cylinder. The plug has several circumferentially spaced partition protrusions. The plug is embedded in the upper port of the cylinder and is fixedly connected to the partition protrusions by screws passing through the outer wall of the cylinder. The gap between two adjacent partition protrusions cooperates with the inner wall of the cylinder to form an ice outlet.

[0005] Chinese Patent 202220227709.5 discloses a spiral ice-making mechanism, including an evaporating cylinder, which includes an ice-making cylinder and an evaporating tube. The ice-making cylinder is a single cylinder, and the evaporating tube is coiled around the outer circumference of the ice-making cylinder. A rotatable ice drill is installed inside the ice-making cylinder. The ice-making cylinder includes an upper flange and a lower flange. The upper flange is connected to an ice-pressing cover. An ice-pushing wheel is installed inside the ice-pressing cover. The ice-pushing wheel rotates together with the axis of the ice drill. An ice drill support is installed on the lower flange, and the ice drill is mounted on the ice drill support.

[0006] The drawbacks of the above technical solution are: complex structure, many parts, low ice-making efficiency, and high ice-making cost.

[0007] Therefore, how to provide an ice-making component that is relatively simple in structure, highly efficient, and low in cost has become a problem that the industry needs to solve. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ice-making component for an ice maker, which has a simple structure, fewer parts, and can increase the ice production capacity of an ice-making component of the same volume by 20%, with obvious cost advantages.

[0009] To achieve the above objectives, this utility model provides an ice-making component for an ice-making machine, the ice-making component comprising:

[0010] Aluminum alloy ice bucket;

[0011] An ice scraper is rotatably mounted inside the ice bucket; the ice scraper is equipped with spiral blades.

[0012] Evaporation tube, located on the outer wall of the ice maker;

[0013] An ice extruder is fixedly connected to the top of the ice-making tank; the ice extruder has several extrusion holes that are larger at the bottom and smaller at the top.

[0014] Short bolts;

[0015] A planar thrust ball bearing; the ice extruder has a central hole for placing a short bolt and the planar thrust ball bearing; the short bolt passes through the planar thrust ball bearing and the central hole and is connected to the upper end of the ice scraper rod.

[0016] In this invention, the ice maker is an extrusion-type granular ice maker.

[0017] The ice bucket is a tubular aluminum alloy ice bucket.

[0018] The ice extruder is made of POM plastic.

[0019] The evaporator tube is spiral-shaped and wrapped around the outer wall of the ice maker; the outside of the evaporator tube is covered with heat-insulating foam to prevent the loss of heat exchange energy and thus save energy consumption of the evaporator tube.

[0020] The center hole is located at the center of the ice extruder, where short bolts and flat thrust ball bearings are placed in sequence.

[0021] The rotation axis of the ice scraper is aligned with the center line of the ice bucket, which makes the ice scraper more stable and effective when scraping and squeezing ice.

[0022] According to another specific embodiment of this utility model, the lower end of the ice squeezing hole is the inlet, and the upper end is the outlet; the inlet area is larger than the outlet area.

[0023] According to another specific embodiment of this utility model, the inlet is an arc-shaped trapezoid and the outlet is circular.

[0024] In this design, compared to a circle, the arc-shaped trapezoidal design at the inlet can minimize the cross-sectional area of ​​the ice column and the end face of the ice extruder, thus minimizing the stress on the ice extruder. This allows the ice extruder to use POM material instead of the existing stainless steel material, reducing costs. The regular circle at the outlet ensures that the final shape of the ice column is circular, making it more acceptable to people. The inside of the extrusion hole smoothly transitions from the arc-shaped trapezoid at the inlet to the circle at the outlet.

[0025] According to another specific embodiment of the present invention, the ice-making assembly further includes a base, and the ice bucket is fixed on the base.

[0026] In this design, the ice extruder is fixedly connected to the base; ice bucket sealing rings are provided between the ice extruder and the ice bucket, and between the ice bucket and the base, to seal the inner cavity of the ice bucket, and a groove is provided to prevent the ice bucket from shifting.

[0027] According to another specific embodiment of the present invention, the base is provided with a water inlet, which is connected to the inner cavity of the ice bucket.

[0028] In this design, water is delivered to the inner cavity of the ice-making bucket through the inlet, and ice layer forms on the inner wall of the ice-making bucket under the action of the evaporation tube.

[0029] According to another specific embodiment of the present invention, a stepped hole is provided inside the central hole.

[0030] According to another specific embodiment of the present invention, the planar thrust ball bearing is disposed in the stepped hole.

[0031] In this design, the bolt cap of the short bolt contacts the upper end of the flat thrust ball bearing; a flat washer is provided between the short bolt and the flat thrust ball bearing.

[0032] According to another specific embodiment of the present invention, the ice-making assembly further includes a motor, which is located below the base and fixedly connected to the base.

[0033] According to another specific embodiment of the present invention, the motor output end passes through the base and the ice-making bucket, and is connected to the ice scraper rod.

[0034] In this design, the motor output is connected to the lower end of the ice scraper rod, which then drives the ice scraper rod to rotate.

[0035] According to another specific embodiment of the present invention, the ice extruder is provided with an inclined surface above it for breaking the ice column extruded from the outlet.

[0036] In this design, the inclined plane and the exit are set up accordingly.

[0037] Compared to currently common technologies, this utility model has a simpler structure and fewer parts (no mushroom head parts, no upper bushing parts, no upper bracket parts, no upper retaining ring, no lower retaining ring parts), and the ice-making capacity of the same volume ice-making component can be increased by 20% (the ice bucket is made of aluminum alloy); the ice extruder is made of POM material (commonly precision-cast stainless steel), and the ice bucket is made of aluminum alloy material (commonly precision-cast stainless steel or ceramic material), making the overall cost of the ice-making component more advantageous.

[0038] The ice-making assembly also includes support columns and long bolts.

[0039] Several support columns are fixed on the outer wall of the ice bucket, and the support columns connect the ice extruder and the base.

[0040] The bolt cap of the long bolt is set on the ice extruder, and the long bolt passes through the ice extruder, support column and base in sequence to be fixedly connected to the motor.

[0041] The ice extruder has a limiting groove inside for limiting the short bolt cap and the flat thrust ball bearing.

[0042] An ice maker includes an outer shell, a front frame, an inner liner, a water tank, an ice storage basket, a drainage system, a water pumping system, an electrical control system, ice-making components, and a refrigeration system; the refrigeration system includes a compressor, a condenser, etc.

[0043] The front panel is located at the front of the ice maker, and the inner liner is located behind the front panel; the water tank and ice storage basket are both located inside the inner liner, with the water tank located above the ice storage basket; the ice-making components are located behind the inner liner.

[0044] An opening communicating with the ice-making component is provided on the upper rear side of the inner liner. The granular ice formed after the ice column is broken by the inclined surface enters the ice storage basket through the opening.

[0045] The pumping system sends water from the water tank into the ice bucket cavity, while the drainage system drains the water that falls during ice making and the melted ice water from the ice storage basket out of the ice maker.

[0046] The working principle of this utility model is as follows:

[0047] 1. When making ice, water enters the inner cavity of the ice bucket through the water inlet of the base; the refrigerant flows through the evaporator tube, and the cooling energy is transferred to the inner wall of the ice bucket through the ice bucket, causing the water to form an ice layer on the inner wall;

[0048] 2. The motor output drives the ice scraper to rotate, and the spiral blades scrape the ice layer into ice shavings and transport the ice shavings to the ice squeezing hole, and continuously push the ice shavings upward into the inlet;

[0049] 3. The ice squeezing hole is larger at the bottom and smaller at the top. The ice sand is continuously squeezed and gradually turns into ice columns. The ice columns grow upward and pass through the outlet until they break off at the slope to form granular ice.

[0050] As the ice scraper rotates, the ice is compressed, which exerts a downward reaction force on the scraper. At the same time, the bolt cap of the short bolt is fixedly connected to the flat thrust ball bearing, and the short bolt is fixedly connected to the ice scraper, which exerts an upward pulling force on the scraper, preventing it from moving downward.

[0051] Therefore, the downward reaction force on the ice scraper will act on the short bolt and the flat thrust ball bearing, forming a pair of action and reaction forces with the upward tension on the ice scraper; the forces are balanced on the short bolt, the flat thrust ball bearing, the ice extruder, and the ice scraper shaft, and the periphery of the ice extruder, as well as parts such as the motor and the ice bucket, will not be subjected to downward or upward forces.

[0052] Compared with currently used technologies, this utility model has the following advantages:

[0053] 1. Simple structure with few parts;

[0054] 2. Using an aluminum alloy ice bucket results in better heat conduction; the thermal conductivity of aluminum alloy is 231 W / (m·K), that of 95% alumina ceramic is 25 W / (m·K), and that of precision-cast SUS304 stainless steel is 12 W / (m·K), demonstrating the significant advantage of aluminum alloy in thermal conductivity.

[0055] 3. The ice bucket has a diameter of 43mm and a height of 90mm. The ice bucket made by aluminum alloy is 20% more ice than that made by ceramic ice bucket, and the cost of aluminum alloy ice bucket is less than 50% of that of ceramic ice bucket, which is a significant cost advantage.

[0056] 4. The production process of aluminum alloy ice buckets is extrusion, which is less difficult; the production process of ceramic ice buckets involves sieving, mixing, pressing, extrusion, sintering, and grinding, which is more difficult.

[0057] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
