Description

Technical Field

[0001] This utility model relates to the technical field of ice-making equipment, and in particular to a scraper for a vertical slush machine. Background Technology

[0002] A slush machine, also known as a slush machine, snow slush machine, snow slush machine, or snow-melting juice machine, is what we commonly call a freezing machine. It is used to process cold desserts, slushies, snow slushies, and other cold drinks. These drinks are suitable for all ages and are an excellent choice for cooling down in the hot summer.

[0003] Existing smoothie machines typically employ a horizontal evaporator structure with a spiral scraper on the outside of the evaporator structure. The smoothie condensed on the outer wall of the evaporator is scraped off and guided to the discharge port through the spiral structure.

[0004] However, horizontally positioned smoothie machines take up a lot of table space and are inconvenient to store; in addition, the spiral-shaped scraper cannot guide the smoothie that falls to the bottom of the beverage container, resulting in smoothie residue. Utility Model Content

[0005] In order to solve the above-mentioned problems in the prior art, this utility model provides a scraper for a vertical smoothie machine.

[0006] The above-mentioned problems of this utility model are solved by the following technical solution: A scraper for a vertical slush machine is used to scrape slush condensed on the outer wall of a vertical cylindrical evaporator. The scraper includes a main body driven by a motor, the main body including an ice scraping strip extending along the axial direction of the evaporator, and an ice shovel at the lower end of the ice scraping strip. The ice shovel and the ice-receiving surface of the slush machine are set at an acute angle.

[0007] A further provision of the above technical solution is that: an ice scraper is provided on one side of the ice scraper along the circumference, and the inner end face of the ice scraper is configured as a protruding ice scraping surface that is attached to the surface of the evaporator.

[0008] A further provision of the above technical solution is that the side of the ice scraper away from the ice scraping strip is provided as an ice scraping edge with a blade structure.

[0009] A further feature of the above technical solution is that the outer end face of the ice scraper is configured as a stepped structure.

[0010] By adopting the above technical solution, the outer end face of the ice scraper has a stepped structure, which reduces the upper contact area to reduce ice and sand adhesion, while the lower part is widened to ensure structural strength. When the ice and sand accumulate to the critical value, it can fall off naturally, avoiding the increase in resistance and the decrease in ice scraping efficiency caused by recondensation.

[0011] A further provision of the above technical solution is that the ice scraper is configured from top to bottom as a first segment and a second segment, wherein the lengths of the first segment and the second segment are not the same; Furthermore, the width of the first segment is smaller than the width of the second segment.

[0012] A further provision of the above technical solution is that the number of ice scrapers is at least two, and the stepped structure on each ice scraper is different.

[0013] By adopting the above technical solution, the stepped structure of each ice scraper is inconsistent, forming an adhesion performance gradient, which further optimizes the ice and sand removal effect and avoids local accumulation.

[0014] A further provision of the above technical solution is that a reinforcing ring is provided at the lower end of the ice scraper, the reinforcing ring being located on the inner side of the ice shovel and used to connect multiple ice scrapers.

[0015] By adopting the above technical solution, a reinforcing ring is set at the lower end of the ice scraper to connect multiple ice scrapers and support the ice shovel, thereby dispersing the impact force when pushing ice and preventing the ice scraper from deforming or breaking.

[0016] A further configuration of the above technical solution is as follows: the main body also includes a drive shaft connected to the motor, and a connecting rib extending radially from the circumferential surface of the drive shaft, wherein the ice scraper is connected to the outer end of the connecting rib; The connecting ribs are designed with an arc shape, and the bending direction of multiple connecting ribs is consistent.

[0017] By adopting the above technical solution, the connecting ribs are arc-shaped and bend in the same direction. Through fluid dynamics design, air resistance can be reduced during high-speed rotation, while ensuring structural dynamic balance, reducing operating noise and vibration, and extending equipment life.

[0018] A further provision of the above technical solution is that the main body also includes a drive shaft connected to the motor, and a connecting rib extending radially from the circumferential surface of the drive shaft; The outer end of the connecting rib is connected to a spiral scraper; The ice scraper is connected to the connecting rib or the spiral scraper.

[0019] A further setting of the above technical solution is that the motor is a brushless motor.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the scraper vertically and combining it with a vertical evaporator, the space occupied by the device is significantly reduced compared to the traditional horizontal evaporator structure, thus improving storage convenience. The ice shovel is set at an acute angle to the ice receiving surface. In conjunction with the rotating motion of the scraper, it can push the scraped ice sand to the discharge port through a "sweeping" or "prying-pushing" action. This solves the problem of traditional spiral scrapers being unable to guide the ice sand to the bottom, resulting in residue, and improves the efficiency of ice sand collection. The inner end face of the ice scraper is a convex ice scraping surface that is attached to the surface of the evaporator, and the outer side is equipped with an ice scraping edge with a blade structure to enhance the cutting force on the ice layer and ensure efficient removal of ice and sand.

Detailed Implementation

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] like Figure 1-4 As shown in the following embodiment, a scraper for a vertical smoothie machine is disclosed.

[0029] Example 1 A scraper for a vertical slush machine is used to scrape the slush that condenses on the outer wall of a vertical cylindrical evaporator 1. The scraper includes a main body 2 driven by a motor. The main body 2 includes an ice scraping strip 2.1 extending along the axial direction of the evaporator 1. An ice shovel 2.2 is provided at the lower end of the ice scraping strip 2.1. The ice shovel 2.2 and the ice receiving surface a of the slush machine are arranged at an acute angle.

[0030] The above is the basic scheme of this embodiment.

[0031] Specific reference Figure 1 As shown, in this embodiment, the evaporator 1 adopts a vertical arrangement design, with its axis L perpendicular to the horizontal plane and installed vertically. The main body 2 of the scraper is located in the external space of the evaporator 1 cylinder, and the ice scraping strip 2.1 is arranged parallel to the extension direction of the axis L of the evaporator 1, with its inner end face maintaining a very small gap distance from the outer wall surface of the evaporator 1. When the motor drives the scraper body 2 to rotate, the cutting edge of the ice scraping strip 2.1 will generate a continuous frictional action with the ice layer condensed on the outer wall surface of the evaporator 1. Through this mechanical scraping action, the ice sand attached to the outer wall of the evaporator 1 can be effectively peeled off.

[0032] The ice slush particles scraped off by the ice scraper 2.1 fall freely under gravity and eventually reach the specially designed ice-receiving surface a at the bottom of the ice slush machine. During this process, the ice shovel 2.2, which operates synchronously with the ice scraper 2.1, also rotates coaxially around the axis L. The shovel surface of the ice shovel 2.2 applies a continuous lateral pushing force to the ice slush falling onto the ice-receiving surface a. This pushing force can gradually push the loose ice slush particles along the inclined direction of the ice-receiving surface a towards the discharge port located at the edge of the ice-receiving surface a, completing the entire ice slush collection and transportation process.

[0033] Preferably, in this embodiment, the driving direction of the motor on the main body 2 is not limited, and the main body 2 can rotate clockwise or counterclockwise.

[0034] When the main body 2 rotates clockwise, an acute-angle space is formed between the blade of the ice shovel 2.2 and the ice-receiving surface a in the forward direction of the rotation. The ice-sweeping space formed by this structure can effectively drive the ice particles in a directional manner in a mechanical motion similar to "sweeping".

[0035] When the main body 2 rotates counterclockwise, an obtuse angle is formed between the blade of the ice shovel 2.2 and the ice-receiving surface a. Under this structure, the tip of the blade can cut into the ice surface, prying up the ice. The end face of the ice shovel 2.2 pushes the loosened ice particles forward through continuous rotation, thus achieving a highly efficient ice surface cleaning effect. This design cleverly utilizes the mechanical properties generated by rotational motion, enabling the ice shovel 2.2 to continuously remove ice particles while maintaining stable contact, effectively improving ice-breaking efficiency.

[0036] The advantage of tilting the ice shovel 2.2 is that its acute angle allows it to contact the ice surface at the optimal cutting angle, ensuring both ice-breaking force and avoiding unnecessary energy loss. This combination of drive method and angle design helps push the ice and sand towards the discharge port, accelerating discharge and ensuring the stability and efficiency of the equipment in de-icing operations.

[0037] To improve ice scraping efficiency, in this embodiment, an ice scraper 2.3 is provided on one side of the ice scraper 2.1 along the circumferential direction, and the inner end face of the ice scraper 2.3 is configured as a protruding ice scraping surface 2.31 that is attached to the surface of the evaporator 1.

[0038] Specific reference Figure 3 and Figure 4 As shown, in this embodiment, the inner end face of the ice scraper 2.1 is set as a working surface 2.13 that matches the surface contour of the evaporator 1. The working surface 2.13 is curved to ensure optimal contact with the evaporator 1. Simultaneously, to ensure safety and flexibility during the de-icing process, a buffer gap is intentionally reserved between the working surface 2.13 and the evaporator 1 to prevent direct contact between the working surface 2.13 and the evaporator 1, which could cause the working surface 2.13 to directly scratch the surface of the evaporator 1. The ice scraper 2.3 is integrally formed on one side of the ice scraper 2.1, and its inner end face is designed as a scraping surface 2.31 that protrudes relative to the working surface 2.13. This stepped height difference design reduces resistance, improves work efficiency, and ensures effective removal of the ice layer during ice scraping, while also preventing damage to the surface of the evaporator 1.

[0039] Preferably, in order to increase the cutting efficiency of the ice scraper 2.3 on the ice layer, in this embodiment, the side of the ice scraper 2.3 away from the ice scraper strip 2.1 is provided as an ice scraper edge 2.32 with a blade structure.

[0040] In this embodiment, one side of the ice scraper 2.1 is designed as a sharp blade-like structure, which significantly enhances the mechanical strength of the ice scraper 2.1, enabling it to withstand and overcome greater ice scraping resistance. Furthermore, it allows the ice scraping edge 2.32 to form a sharper contact angle with the cylindrical surface of the evaporator 1, making its ice scraping end more pointed and protruding compared to the traditional planar ice scraper 2.1. This optimized geometry ensures that the ice scraper 2.1 forms the best contact state with the surface of the evaporator 1, thereby greatly improving the efficiency of ice removal and achieving a more ideal overall ice scraping effect.

[0041] During the rotation of the main body 2, the ice scraper 2.1 generates a large amount of fine ice sand when cutting the ice layer. Most of this ice sand falls off naturally, but a small amount adheres to the surface of the ice scraper 2.1 due to surface tension. As the cutting operation continues, this adhered ice sand gradually accumulates to form a thin layer. If the accumulation exceeds a critical value, in a low-temperature environment, this loose ice sand will re-condense and solidify, eventually forming a hard ice block. This ice block not only increases the running resistance of the ice scraper 2.1 but also significantly reduces the contact pressure between the ice scraper 2.1 and the ice layer, thus seriously affecting the scraping efficiency and service life of the ice scraper 2.1 on the surface of the evaporator 1. Therefore, in this embodiment, the outer end face of the ice scraper 2.1 is set as a stepped structure.

[0042] Based on the above setup, when ice shavings accumulate on the end face of the ice scraper 2.1 and reach a critical adhesion amount, the end face of the ice scraper 2.1 is completely covered by ice shavings and reaches saturation, so its surface cannot continue to bear and adhere to more ice shavings. At this point, the adhesion between the ice shavings and the ice scraper 2.1 has reached its limit, and under the combined influence of gravity and mechanical vibration, the ice shavings will naturally fall off the surface of the ice scraper 2.1. By designing the ice scraper 2.1 as a stepped structure with a significant height difference, the actual width of the upper part of the ice scraper 2.1 can be significantly reduced. This structural design can effectively reduce the contact area and adhesion area of ​​ice shavings on the upper part of the ice scraper 2.1. At the same time, the lower part of the ice scraper 2.1 adopts a relatively large width design. This structural configuration not only ensures the overall structural stability of the ice scraper 2.1, but also ensures that the ice scraper 2.1 has sufficient mechanical support strength and anti-deformation ability during operation, thereby meeting the requirements for long-term stable operation of the equipment.

[0043] Preferably, in this embodiment, the ice scraper 2.1 is configured from top to bottom as a first segment 2.11 and a second segment 2.12, and the lengths of the first segment 2.11 and the second segment 2.12 are not the same; Furthermore, the width of the first segment 2.11 is smaller than the width of the second segment 2.12.

[0044] In other embodiments, more segments may be provided.

[0045] In this embodiment, to optimize the overall performance of the ice scraper 2.1, a segmented differentiated design scheme was adopted in its structural design. Specifically, the first segment 2.11 in the upper region uses a relatively narrow width, which effectively reduces the critical value for ice and sand adhesion and accumulation in this area, thereby significantly improving the de-icing effect. Meanwhile, the second segment 2.12 in the lower region uses a significantly wider width, which not only enhances the overall structural stability of the ice scraper 2.1 but also greatly improves its mechanical support strength, ensuring that the device maintains excellent durability even under prolonged high-intensity operation. Through this innovative design of differentiated widths in the upper and lower segments, the ice scraper 2.1 achieves simultaneous optimization in two key performance indicators: anti-adhesion and mechanical strength.

[0046] Preferably, in this embodiment, the number of ice scraping strips 2.1 is at least two, and the stepped structure on each ice scraping strip 2.1 is different.

[0047] In other words, the length and width of the first segment 2.11 on different ice scraper strips 2.1 vary significantly. This difference is not only reflected in the differences between segments within a single ice scraper strip 2.1, but also in the comparison between different ice scraper strips 2.1. Similarly, the length and width parameters of the second segment 2.12 also exhibit inconsistent characteristics. Based on this difference, the ice scraper strips 2.1 on the main body 2 structure will exhibit differentiated adhesion performance at different locations, and this gradient change in adhesion ability is continuous and controllable. At the same time, this dimensional difference also leads to inconsistent critical values ​​in each segment, enabling the ice scraper strips 2.1 to achieve an optimal balance in overall performance. This asymmetrical design ensures that the ice scraper strips 2.1 maintain a stable de-icing effect under different working conditions, while avoiding material fatigue problems caused by stress concentration.

[0048] In this embodiment, to further enhance the strength of the ice scraper 2.1 and ensure the pushing efficiency of the ice shovel 2.2, a reinforcing ring 2.4 is provided at the lower end of the ice scraper 2.1. The reinforcing ring 2.4 is located on the inner side of the ice shovel 2.2 and is used to connect multiple ice scrapers 2.1.

[0049] In this embodiment, refer to Figure 2 As shown, the reinforcing ring 2.4 is a ring-shaped structure, integrally formed at the lower end of the ice scraper 2.1 and located inside the ice scraper 2.2, providing axial support for the ice scraper 2.2. The main function of the reinforcing ring 2.4 is to enhance the structural strength of the ice scraper 2.1, while also effectively dispersing the impact force borne by the ice scraper 2.2 during ice pushing. Its ring-shaped design not only ensures the stability of the connection but also prevents the ice scraper 2.1 from deforming or breaking during use. This structural design makes the entire ice removal tool more durable and reliable, capable of withstanding greater external forces.

[0050] In this embodiment, the main body 2 further includes a drive shaft 2.5 connected to the motor, and a connecting rib 2.6 extending radially from the circumference of the drive shaft 2.5, and the ice scraper 2.1 is connected to the outer end of the connecting rib 2.6; The connecting rib 2.6 is configured as an arc-shaped structure, and the bending direction of multiple connecting ribs 2.6 is consistent.

[0051] Specific reference Figure 2 As shown, the drive shaft 2.5 has a shaft hole, and the output shaft of the motor is connected to the shaft hole, thereby driving the drive shaft 2.5 to rotate. Several connecting ribs 2.6 extending radially outward are evenly distributed on the circumferential surface of the drive shaft 2.5, and the connecting ribs 2.6 and the drive shaft 2.5 are integrally formed. The ice scraper 2.1 is also integrally formed and connected to the outermost end of the connecting ribs 2.6, forming a complete scraper structure.

[0052] Of particular note is that all connecting ribs 2.6 are designed with an arc shape, and this arc profile is optimized for fluid dynamics. The bending direction of multiple connecting ribs 2.6 is completely consistent, all bending in the same direction of rotation. This consistent design ensures optimal dynamic balance performance at high speeds, while improving ice-scraping efficiency and reducing air resistance during operation.

[0053] Preferably, in this embodiment, the motor is a brushless motor.

[0054] Example 2 This embodiment provides a new main structure, the purpose of which is to increase the scraping area on the evaporator surface, thereby increasing the ice scraping efficiency.

[0055] The specific implementation is as follows: the main body 2 also includes a drive shaft 2.5 connected to the motor, and a connecting rib 2.6 extending radially from the circumferential surface of the drive shaft 2.5; The outer end of the connecting rib 2.6 is connected to a spiral scraper 2.7; The ice scraper 2.1 is connected to the connecting rib 2.6 or the spiral scraper 2.7.

[0056] Specific reference Figure 5 As shown, two connecting ribs 2.6 extend symmetrically from the outer periphery of the drive shaft 2.5, and the connecting ribs 2.6 are set in an arc shape. At the same time, the bending directions of the two connecting ribs 2.6 are the same.

[0057] The outer ends of the two connecting ribs 2.6 are respectively connected to a spiral scraper 2.7, and the other end of the spiral scraper 2.7 is connected to the middle part of the ice scraper 2.1 to support the ice scraper 2.1 in a spiral direction.

[0058] It should be noted that in this embodiment, the spiral scraper 2.7 maintains a very small gap with the surface of the evaporator 1, and the two are in near-zero-distance contact, enabling the spiral scraper 2.7 to efficiently and precisely cut the ice layer formed on the surface of the evaporator 1. The cut ice will rotate and slide down the specially designed spiral surface of the spiral scraper 2.7, and will eventually be smoothly guided to the ice receiving surface a below.

[0059] This spiral flow guide structure not only effectively prevents the accumulation of ice and sand, but also ensures the continuity and efficiency of the cutting process.

[0060] Meanwhile, this embodiment is provided with multiple ice scraping strips 2.1, two of which are connected to the connecting rib 2.6, and the remaining ice scraping strips 2.1 are connected to the middle position of the spiral scraper 2.7. This support structure not only provides sufficient axial support for the spiral scraper 2.7, but also ensures the stability and balance of the entire ice scraping system when it is running at high speed.

[0061] Preferably, the number of ice scraping strips 2.1 is the sum of the number of connecting ribs 2.1 and the number of spiral scrapers 2.7.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
