Description

Technical Field

[0001] This utility model relates to the field of ice-making equipment technology, and in particular to a snow melting machine that is easy to stir. Background Technology

[0002] A slush machine is a commercial or household device that makes cold drinks by rapidly crushing ice cubes and mixing them with ingredients. Its core working principle is to use a refrigeration system to lower the temperature of the inner wall of the ice maker below freezing point, then pour drinking water into the ice maker. The water gradually freezes into ice on the inner wall of the ice maker. Then, a rotating stirring scraper scrapes against the inner wall of the ice maker, scraping off the frozen ice layer to form fine snowflakes or shaved ice.

[0003] However, in existing snow melting machines, the growth rate and thickness of ice crystals on the vertical direction of the ice-making cylinder's inner wall may be uneven during the ice-making process. This is because the traditional smooth inner wall or simple straight rib design has limited guiding and breaking effects on ice crystals. When the stirring scraper rotates, it mainly relies on its own blades for scraping. For ice layers in the middle of the cylinder or far from the scraper, the transmission of stirring force is poor, easily leading to ice clumping and the creation of stirring dead zones. The final ice product has an unsatisfactory fineness and uniformity. In addition, due to the aforementioned uneven stirring, the equipment motor often needs to overcome greater resistance, resulting in increased energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a snow melting machine that facilitates stirring, preventing the phenomenon that ice shavings cannot be scraped off by the stirring scraper due to synchronous rotation along the concentric circle of the ice-making cylinder, effectively improving the uniformity of ice mixing, and thus improving the fineness of the final ice product.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a snow melting machine that facilitates stirring, comprising a body and an ice-making cylinder, wherein the body has an ice-making cavity for accommodating the ice-making cylinder, the ice-making cavity has an ice outlet, an evaporator fixedly connected to the body is disposed inside the ice-making cavity, a stirring scraper is disposed circumferentially on the evaporator, and ribs extending axially are disposed on the inner wall of the ice-making cylinder, the rotation path of the stirring scraper corresponds to the outer surface of the ribs, and is used to scrape off the ice layer covering the ribs, the width of the ribs gradually decreases along the ice outlet direction of the ice-making cylinder, so that the outer surface of the ribs gradually moves away from the central axis of the ice-making cylinder.

[0006] By adopting the above technical solution, when the ice layer shrinks slightly due to low temperature or is stressed due to scraping, it will be easier to loosen and detach from the wider part to the narrower part. This reduces the adhesion of the ice layer to the ice cylinder wall, and reduces the torque and resistance required for the stirring scraper to scrape the ice. This makes it easier for the ice layer to be scraped off by the stirring scraper, and also reduces the motor load and makes the operation more stable.

[0007] A further feature of this invention is that the ribs are distributed in a stepped manner, forming multiple discontinuous stepped segments.

[0008] By adopting the above technical solution, the stepped shape will produce abrupt changes in width at the corners of the steps. When the ice layer freezes and wraps around the steps, a huge stress concentration will occur at the corners of the steps. After the stirring scraper applies force, the ice layer will preferentially break from these discontinuous step corners and the top of the ribs, thus naturally breaking into small ice flakes of uniform size, making it easier for the ice layer to be scraped off by the stirring scraper. In addition, the discontinuous small ice flakes produced by the stepped section have better fluidity and are easier to be transported and discharged by the stirring scraper. The ice chips of this shape have higher fluffiness and a taste closer to the ideal "snowflake" shape, avoiding the problem of clumping or compaction caused by excessively long ice chips, effectively improving the uniformity of ice mixing, and making the final ice product more delicate.

[0009] A further feature of this invention is that the transition portion between the stepped sections is an inclined surface.

[0010] By adopting the above technical solution, the stepped section, through a smooth slope transition, eliminates abrupt changes in working resistance, making the motor's operating torque more stable, significantly reducing noise and vibration, and reducing impact wear on components, thereby improving the overall reliability and lifespan of the machine. On the other hand, it guides the ice layer to tear smoothly and assists in lifting ice chips, thus achieving a more stable and efficient operating state.

[0011] A further feature of this invention is that: the ice-making cylinder is provided with a first rib in the circumferential direction, the ice-making cavity is provided with a second rib, the second rib is provided with a groove for accommodating the first rib, and the first rib is engaged with the groove.

[0012] A further feature of this invention is that: both the first rib and the second rib are provided in multiples, and are located on the same horizontal plane and spaced apart; the end of the second rib near the adjacent second rib is provided with a guide slope, and the guide slope is inclined toward the adjacent second rib.

[0013] By adopting the above technical solution, when the user places the ice maker, the first rib automatically slides into the slot position under the guidance of the inclined surface of the second rib after contacting the guide surface of the second rib. This reduces the requirements for installation accuracy, has a foolproof effect, achieves fast and smooth installation, and improves the convenience and user experience.

[0014] A further feature of this invention is that the stirring scraper head includes a hollow support and a spiral scraper and an ice-shoveling part disposed on the hollow support, wherein the ice-shoveling part is used to guide the ice shavings in the ice-making chamber to the ice outlet.

[0015] A further feature of this invention is that the ice-shoveling part is configured to be inclined, and the ice-shoveling part forms a non-perpendicular inclination angle with the bottom wall of the ice-making cavity.

[0016] By adopting the above technical solution, the ice slush can be easily pushed, thereby reducing flow resistance and allowing the ice slush to move more smoothly and quickly toward the ice outlet.

[0017] A further feature of this invention is that the hollow support includes a lower ring and an upper rod that are perpendicular to each other, the spiral scraper is disposed on the upper rod and forms axial support through the upper rod, and the ice-scraping part is disposed on the lower ring and protrudes from the bottom surface of the lower ring.

[0018] By adopting the above technical solution, the stirring scraper head forms a stable frame structure, which is reasonable and easy to implement.

[0019] A further feature of this invention is that a temperature sensor is provided on the bottom wall of the ice-making chamber, and the temperature sensor is electrically connected to the controller inside the snow melting machine.

[0020] By adopting the above technical solution, the temperature inside the ice-making chamber can be effectively monitored, ensuring the stability and consistency of the ice quality.

[0021] A further feature of this invention is that a valve is provided below the ice outlet, the valve includes a valve core, a valve stem is provided along the axial direction of the valve core, a handle is hinged to the valve stem, and a torsion spring is provided on the valve stem for resetting the handle.

[0022] By adopting the above technical solutions, the convenience and efficiency of ice retrieval have been improved, and the user experience has been enhanced.

[0023] In summary, this utility model has the following beneficial effects: 1. Ribs extending axially along the inner wall of the ice maker are used. The width of the ribs gradually decreases along the direction of the ice maker's opening, so that the outer surface of the ribs gradually moves away from the central axis of the ice maker. The ribs form a structure that is narrow at the top and wide at the bottom to facilitate the demolding of ice blocks. Because the ribs are composed of wide and narrow structures, when the ice layer shrinks slightly due to low temperature or is stressed due to scraping, it will be easier to loosen and detach from the wider part to the narrower part. This reduces the ice layer's gripping effect on the ice maker's wall, and reduces the torque and resistance required for the stirring scraper to scrape the ice. This makes it easier for the ice layer to be scraped off by the stirring scraper, and also reduces the motor load and makes the operation more stable.

[0024] 2. The ice is produced using a stepped distribution of ribs, forming multiple discontinuous stepped segments. This stepped structure creates abrupt changes in width at the corners. When the ice layer solidifies and envelops the steps, significant stress concentration occurs at these corners. When the stirring scraper applies force, the ice layer preferentially breaks off from these discontinuous step corners and the tops of the ribs, naturally breaking into uniformly sized small ice flakes. This makes the ice layer easier for the stirring scraper to remove. Furthermore, the discontinuous ice flakes produced by the stepped segments have better fluidity, making them easier to transport and discharge by the stirring scraper. This prevents the ice shavings from rotating concentrically along the ice-making cylinder and failing to be scraped off. The resulting ice flakes also have higher fluffiness, producing a texture closer to the ideal "snowflake" shape. This avoids clumping or compaction caused by excessively long ice flakes, effectively improving the uniformity of ice mixing and resulting in a smoother final product.

[0025] 3. The transition between the stepped sections is made of an inclined surface. The stepped sections are smoothly transitioned by an inclined surface, which on the one hand eliminates the sudden change in working resistance, making the motor's running torque more stable, significantly reducing noise and vibration, and reducing the wear of components due to impact, thus improving the reliability and life of the whole machine. On the other hand, it guides the ice layer to tear smoothly and assists in the lifting of ice chips, thereby achieving a more stable and efficient operating state. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] A snow melting machine that facilitates stirring, such as Figure 1-7 As shown, the device includes a body 1 and an ice-making cylinder 2. The body 1 has an ice-making chamber 3 for accommodating the ice-making cylinder 2. A sealing ring 6 is provided at the joint between the ice-making chamber 3 and the ice-making cylinder 2. An ice outlet 34 is provided on the ice-making chamber 3. An evaporator 4 is fixedly connected to the body 1 and located at the center of the ice-making chamber 3. A stirring scraper 5 is provided around the evaporator 4. Its working principle is as follows: the ice-making cylinder 2 is placed into the ice-making chamber 3 and sealed and fixed. Water or other liquid beverages are added to the ice-making cylinder 2. When the snow melting machine is working, the temperature of the evaporator 4 drops rapidly to below zero. The inner wall of the ice-making cylinder 2 exchanges heat with the low-temperature evaporator 4, and its temperature also drops sharply. The water or other liquid beverages in the ice-making cylinder 2 come into contact with the cold inner wall of the ice-making cylinder 2 and begin to gradually freeze into ice. Then, the drive mechanism (such as a motor) drives the stirring scraper head 5 to rotate around the fixed evaporator 4. The rotating stirring scraper head 5 scrapes the ice on the inner wall of the ice-making cylinder 2. Finally, the ice chips are pushed to the ice outlet 34 of the ice-making cylinder 2 and discharged outside the cylinder.

[0036] The inner wall of the ice-making cylinder 2 is provided with ribs 21 extending along its axial direction. The rotation path of the stirring scraper head 5 corresponds to the outer surface of the ribs 21 and is used to scrape off the ice layer covering the ribs 21. The width of the ribs 21 is gradually reduced along the ice outlet direction of the ice-making cylinder 2 and along the direction of the opening end of the ice-making cylinder 2, so that the outer surface of the ribs 21 gradually moves away from the central axis of the ice-making cylinder 2. The ribs 21 form a structure that is narrower at the top and wider at the bottom (viewed from the open end of the ice cylinder 2) to facilitate the demolding of ice blocks. The specific explanation is as follows: Since the ribs 21 are composed of a wide and narrow structure, when the ice layer shrinks slightly due to low temperature or is stressed due to scraping, it will be easier to loosen and detach from the wider part to the narrower part. Especially when the ribs 21 are set in the vertical direction, the ice layer is more likely to loosen and fall off under the action of gravity. This reduces the gripping effect of the ice layer on the wall of the ice cylinder 2, which reduces the torque and resistance required for the stirring scraper head 5 to scrape the ice. This makes it easier for the ice layer to be scraped off by the stirring scraper head 5, and also reduces the load on the motor, making the operation more stable.

[0037] Preferably, the ribs 21 are distributed in a stepped shape, forming multiple discontinuous stepped segments 211. The stepped shape creates abrupt changes in width at the corners of the steps. When the ice layer freezes and envelops the steps, a huge stress concentration occurs at the corners of the steps. After the stirring scraper 5 applies force, the ice layer will preferentially break from these discontinuous stepped corners and the top of the ribs 21, thus naturally breaking into small ice flakes of uniform size. This makes it easier for the ice layer to be scraped off by the stirring scraper 5. In addition, the discontinuous small ice flakes produced by the stepped segments 211 have better fluidity and are easier to be transported and discharged by the stirring scraper 5. This prevents the phenomenon that the ice shavings cannot be scraped off by the stirring scraper because they rotate synchronously along the concentric circles of the ice-making cylinder 2. Moreover, the ice shavings of this shape have higher fluffiness and a texture closer to the ideal "snowflake" shape. This avoids the problem of clumping or compaction caused by excessively long ice shavings, effectively improving the uniformity of ice mixing and making the final ice product more delicate.

[0038] Preferably, the transition portion between the stepped segments 211 is an inclined surface 212. Through the above design, the abrupt break point is transformed into a gradual transition point. The smooth inclined transition eliminates the abrupt change in working resistance, making the motor's operating torque more stable, significantly reducing noise and vibration, and reducing impact wear on components, thus improving the overall reliability and lifespan of the machine. On the other hand, it guides the ice layer to tear smoothly and assists in the lifting of ice chips, thereby achieving a more stable and efficient operating state.

[0039] Preferably, the ice-making cylinder 2 is provided with a first protruding rib 22 circumferentially, and the ice-making cavity 3 is provided with a second protruding rib 31. The second protruding rib 31 has a slot 32 for receiving the first protruding rib 22, and the first protruding rib 22 is engaged with the slot 32. The first protruding rib 22 is aligned with the slot 32 on the second protruding rib 31 and rotated into place, so that the ice-making cylinder 2 is fixedly connected to the ice-making cavity 3.

[0040] Preferably, multiple first ribs 22 and second ribs 31 are provided, located on the same horizontal plane and spaced apart. A guide slope 33 is provided at the end of each second rib 31 near the adjacent second rib 31, and the guide slope 33 is inclined towards the adjacent second rib 31. With this structure, when the user places the ice maker 2, the first rib 22, after contacting the guide slope 33 of the second rib 31, automatically slides into the slot 32 under the guidance of the slope. This reduces the requirement for installation accuracy, has a foolproof effect, achieves fast and smooth installation, and improves ease of use and user experience.

[0041] Preferably, the stirring scraper head 5 includes a hollow support 51 and a spiral scraper 52 and an ice-scraping part 53 disposed on the hollow support 51. The hollow support 51 is adapted to the shape of the cylindrical evaporator 4 and is sleeved on the outside of the evaporator 4. The spiral scraper 52 and the ice-scraping part 53 are integrally formed with the hollow support 51. The ice-scraping part 53 is used to guide the ice shavings in the ice-making chamber 3 to the ice outlet 34. With the above design, the driving mechanism (such as a motor) drives the stirring scraper head 5 to rotate around the fixed evaporator 4. The rotating spiral scraper 52 scrapes the ice blocks on the inner wall of the ice-making cylinder 2 to the bottom of the ice-making chamber 3. Finally, the ice shavings are pushed by the ice-scraping part 53 to the ice outlet 34 of the ice-making cylinder 2 and discharged outside the cylinder.

[0042] Preferably, the ice-shoveling part 53 is configured at an angle, forming a non-perpendicular angle with the bottom wall of the ice-making chamber 3. Through this structural design, the ice sand contacted by the ice-shoveling part 53 slides along this inclined surface. The force acting on it can be decomposed into a force that propels it forward and a force that lifts it upward and guides it towards the ice outlet, allowing the ice sand to be easily pushed, thereby reducing flow resistance and enabling the ice sand to move more smoothly and quickly towards the ice outlet. In a preferred embodiment, the ice-shoveling part 53 can be configured to abut against the bottom wall of the ice-making chamber 3. The inclined leading edge of the ice-shoveling part 53 more easily cuts into the bottom ice sand layer, using its sharp edge and bevel to "pry" and "cut" the ice sand off the bottom wall. This cutting action has less pushing resistance than a vertical ice-shoveling part 53, resulting in higher ice-clearing efficiency and effectively preventing the ice sand from being compacted, ensuring that the ice sand at the bottom of the ice-making chamber 3 is thoroughly removed.

[0043] Preferably, the hollow support 51 includes a lower ring body 511 and an upper rod body 512 that are perpendicular to each other. The lower ring body 511 and the upper rod body 512 are integrally formed. The lower ring body 511 is arranged radially along the evaporator 4, and the upper rod body 512 is arranged axially along the evaporator 4, forming a frame structure adapted to the shape of the evaporator 4. The spiral scraper 52 is arranged on the upper rod body 512 and forms axial support through the upper rod body 512, ultimately making the stirring scraper head 5 form a stable frame structure. The ice scraping part 53 is arranged on the lower ring body 511 and protrudes from the bottom surface of the lower ring body 511, so that the ice scraping part 53 can complete the scraping and guiding functions without interference. The structure is reasonable and easy to implement.

[0044] Preferably, a mounting hole is provided on the bottom wall of the ice-making chamber 3, and a temperature sensing probe 35 is fixedly installed in the mounting hole. The temperature sensing probe 35 can be a thermistor. The temperature sensing end of the temperature sensing probe 35 is tightly attached to the inner surface of the bottom wall to accurately sense the temperature change at the bottom of the ice-making chamber 3. To prevent water leakage from the temperature sensing probe 35, thermally conductive silicone grease or a sealing ring can be filled between the temperature sensing probe 35 and the mounting hole. The temperature sensing probe 35 is electrically connected to the controller inside the snow melting machine through a wire. The controller is used to receive and process the temperature signal transmitted by the temperature sensing probe 35. Through the above structure, the temperature inside the ice-making chamber 3 is effectively monitored, ensuring the stability and consistency of the ice quality.

[0045] Preferably, a valve is provided below the ice outlet 34. The valve is preferably a shut-off valve, comprising a valve core 41, with a valve stem 42 arranged axially along the valve core 41. The valve core 41 and valve stem 42 are integrally formed. A handle 43 is hinged to the valve stem 42, and a torsion spring 44 is provided on the valve stem 42 to reset the handle 43. Rotating the handle 43 opens or closes the valve, and the torsion spring 44 causes the handle 43 to have a rotational tendency in the opposite direction of rotation. By providing the torsion spring 44, the convenience and efficiency of ice removal are improved, enhancing the user experience.

[0046] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
