Description

Technical Field

[0001] This utility model relates to the field of snow ice machine technology, and specifically to a snow ice machine with an ice scraper and anti-icing structure. Background Technology

[0002] While the ice scraper is not a core component of a shaved ice machine, its placement directly affects the quality of the produced shaved ice. For example, in Chinese invention patent application CN119563747A, the traditional shaved ice machine's ice scraper is directly fixed to the frame and positioned corresponding to the evaporator. Due to the lack of an effective protective structure, this design has significant drawbacks when processing ingredients with low freezing points. When processing easily frozen ingredients such as water, the blade edge and back quickly freeze, forming a thick ice layer. This not only significantly reduces scraping efficiency and causes uneven scraping but also results in food waste. The ice layer alters the clearance between the ice scraper and the evaporator, affecting the scraping angle and thus reducing the quality of the shaved ice. Furthermore, ice buildup increases the motor load, affecting the machine's lifespan. Although existing technologies offer various ice scraper improvements, most focus on blade shape optimization and lack effective solutions for the crucial issue of preventing icing.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0004] The purpose of this invention is to provide a shaved ice machine with an anti-icing structure for the ice scraper, which has the advantages of effectively preventing the ice scraper from icing, improving ice scraping efficiency, reducing food waste, and extending the service life of the equipment.

[0005] This utility model provides a snow ice machine with an anti-icing structure and an ice scraper, including a frame and a liquid container. The frame has an open receiving cavity, and an evaporator and an ice scraper are correspondingly arranged in the upper part of the receiving cavity. The ice scraper is located on the side of the evaporator near the opening. The key feature is that the liquid container is inserted into the lower part of the receiving cavity through the opening, and a protective plate is provided on the liquid container. When the liquid container is inserted into the lower part of the receiving cavity, the front side of the protective plate is pressed against the outside of the ice scraper to form an anti-icing structure.

[0006] Furthermore, this utility model proposes that the protective sheet be made of plastic.

[0007] Furthermore, this utility model proposes that the liquid container is a plastic container, and the protective sheet is integrally formed with the liquid container.

[0008] Furthermore, this utility model also proposes that an inlet groove is provided on the opening frame of the receiving cavity, and an inlet block is provided on the rear side wall of the liquid box. The inlet groove and the inlet block are matched and matched accordingly. When the inlet block is inserted into the inlet groove, the liquid box is installed in place.

[0009] Furthermore, this utility model also proposes that a material box is provided on the frame, the bottom of the material box is placed in the receiving cavity, and a discharge valve is provided at the bottom of the material box; a rib is provided on the liquid box, the rib corresponds to the discharge valve, and when the liquid box is installed in place, the rib opens the discharge valve.

[0010] Furthermore, this utility model also proposes that an inclined plate is provided at the bottom of the front end of the receiving cavity. When the liquid box is inserted into the lower part of the receiving cavity, the front end of the liquid box is raised along the inclined plate so that the rib can open the material valve.

[0011] Furthermore, this utility model also proposes that a handle is provided at the rear end of the liquid container to facilitate the insertion and removal of the liquid container.

[0012] Furthermore, this utility model also proposes that the liquid container is provided with a discharge port, which is located behind the protective sheet, and a cup is provided on the frame, with the cup corresponding to the discharge port.

[0013] Furthermore, this utility model also proposes that a door body be installed on the opening.

[0014] As can be seen from the above, the snow ice machine with an anti-icing structure for the ice scraper provided by this utility model, when installed by inserting and removing the liquid box, makes the protective plate stick tightly to the outside of the ice scraper to form an anti-icing structure, which effectively prevents the food from directly contacting the ice scraper, inhibits the formation of ice layer, and has the advantages of significantly improving the uniformity of ice scraping, reducing the motor load and extending the service life of the equipment.

[0021] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0022] In existing technologies, the problem of ice accumulating on the surface of the ice scraper during the production of shaved ice machines has been a long-standing issue. Traditional equipment fixes the ice scraper directly to the frame without any protective structure, causing ice to easily form on the blade edge and back in low-temperature environments. This not only affects scraping efficiency but also leads to food waste. Especially when processing liquids with low freezing points, the ice buildup accelerates, requiring operators to frequently stop the machine for cleaning, severely limiting the equipment's continuous operation capability.

[0023] To address the aforementioned problems, the inventors of this application first observed that ice formation is directly related to the environment in which the ice scraper is exposed. Analysis revealed that water vapor or droplets contacting the cryogenic blade is the primary cause of icing. This led to the initial idea of ​​isolating the blade from the external environment. Further considering the limitations of the equipment structure, physical isolation was necessary while ensuring normal ice scraping functionality. After numerous experiments and verifications, a protective plate was ultimately added to the liquid tank, along with a pull-out installation structure, achieving both blade coverage and ease of daily maintenance.

[0024] like Figure 1-4 As shown, this utility model proposes a snow ice machine with an anti-icing structure for ice scrapers, including a frame 1 and a liquid container 2. The frame 1 has a receiving cavity 11 with an opening 13. An evaporator 3 and an ice scraper 6 are correspondingly arranged in the upper part of the receiving cavity 11. The ice scraper 6 is located on the side of the evaporator 3 near the opening 13. The liquid container 2 is inserted into the lower part of the receiving cavity 11 through the opening 13. A protective plate 22 is provided on the liquid container 2. When the liquid container 2 is inserted into the lower part of the receiving cavity 11, the front side of the protective plate 22 is pressed against the outside of the ice scraper 6 to form an anti-icing structure.

[0025] The "slip-in design within the receiving cavity 11" means that the liquid container 2 can be pushed into or pulled out of its installation position along a specific track. The protective plate 22's front side being close to the outer side of the ice scraper 6 means that after installation, the protective plate 22 forms surface contact with the ice scraper 6. The front side of the protective plate 22 is determined based on the front-to-rear direction of the liquid container 2; the front side of the protective plate 22 refers to the side closest to the front of the liquid container 2, and the outer side of the ice scraper 6 refers to the side facing the opening 13. The anti-icing structure refers to a structure that physically blocks moisture from contacting the ice scraper 6, and its coverage area at least includes the area of ​​the ice scraper 6 prone to icing.

[0026] Specifically, when the liquid tank 2 is fully pushed in, the protective plate 22 elastically deforms and adheres tightly to the outside of the ice scraper 6. At this time, the protective plate 22 covers the outside of the ice scraper 6, blocking the path of external liquid splashing or water vapor condensation. When the evaporator 3 is continuously cooling, the contact surface between the protective plate 22 and the ice scraper 6 remains dry to prevent ice crystal formation. When maintenance is required, the operator can directly pull out the liquid tank 2 to clean the surface of the protective plate without disassembling the blade assembly.

[0027] Compared to existing technologies, traditional ice scrapers 6 are completely exposed to the working environment, while this invention achieves dynamic isolation through a detachable protective structure. Existing technologies rely on manual de-icing during shutdown, while this invention prevents ice accumulation during continuous operation. The combined design of the protective plate 22 and the pull-out structure significantly simplifies the equipment maintenance process while ensuring functionality.

[0028] Through the above technical solution, this utility model effectively blocks direct contact between water vapor and the ice scraper 6, fundamentally eliminating the conditions for ice formation on the outside of the ice scraper 6. The elastic contact design of the protective plate 22 ensures that the isolation effect is not affected by equipment vibration, and the pull-out structure facilitates quick replacement or cleaning of the protective components. This solution maintains the original ice scraping efficiency while extending the continuous operation time of the equipment and reducing food residue loss.

[0029] This utility model further proposes that the protective sheet 22 is made of plastic sheet.

[0030] The plastic sheet refers to a thin sheet structure made of high-molecular polymer materials, specifically polypropylene or polyethylene, which have low thermal conductivity and smooth surface properties. Low thermal conductivity effectively reduces the heat exchange rate between the ice scraper blade 6 and the external environment, lowering the likelihood of ice formation on the outside of the ice scraper blade 6; the smooth surface property, through physical isolation, prevents ice crystals from adhering to and accumulating on the outside of the blade.

[0031] Specifically, when the plastic sheet is attached to the outside of the ice scraper, its low thermal conductivity inhibits the rapid drop in surface temperature, preventing water vapor from quickly condensing into ice due to excessive temperature differences. Simultaneously, the physical barrier formed by the smooth surface prevents ice crystals from stably adhering to the outside of the ice scraper 6, thus preventing ice accumulation. This structure maintains the normal ice scraping function of the ice scraper 6 while actively intervening in the icing process through material properties.

[0032] This utility model further proposes that the liquid container 2 is made of plastic, and the protective sheet 22 is integrated with the liquid container 2 through an integral molding process.

[0033] The plastic box 2 refers to a container made of thermoplastic or thermosetting polymer material, which can be achieved through injection molding. Its material properties can reduce the overall weight of the liquid container 2, while maintaining material consistency with the protective sheet 22. One-piece molding means that the protective sheet 22 and the liquid container 2 are formed into a single structure through a mold during the manufacturing process.

[0034] Specifically, after the plastic box 2 and the protective sheet 22 are processed using an integrated molding process, they form a continuous material interface in their microstructure, without any physical seams or adhesive layers. In low-temperature operating environments, due to the consistent thermal expansion coefficient of the plastic materials, the contact surface between the protective sheet 22 and the liquid container 2 will not experience stress concentration due to temperature changes, thus maintaining a tight fit. This process also eliminates the need for separate installation steps for the protective sheet; for example, it eliminates the need for screws, clips, or glue for fixing, and the structural integration can be completed directly through molding.

[0035] This utility model further proposes to set an inlet groove 15 on the frame of the opening 13 of the receiving cavity 11 and an inlet block 21 on the rear side wall of the liquid box 2. The inlet groove 15 and the inlet block 21 are matched and matched accordingly. When the inlet block 21 is inserted into the inlet groove 15, the liquid box 2 is installed in place.

[0036] The inlet groove 15 refers to the groove structure opened on the edge of the opening 13. Its channel extends in the same direction as the insertion direction of the liquid box 2, and is used to guide the inlet block 21 to move along a predetermined path. The inlet block 21 refers to the protruding structure extending outward from the side wall of the liquid box 2. Its shape forms a clearance fit with the inner contour of the inlet groove 15, and is mechanically limited to force alignment with the installation trajectory.

[0037] Specifically, when the operator inserts the liquid container 2 into the receiving cavity 11, the guide block 21 first contacts the guide ramp at the entrance of the guide groove 15 and automatically slides into the guide groove 15 under the pushing force. When the guide block 21 reaches the end of the guide groove 15, the rear side wall of the liquid container 2 forms a surface contact with the edge of the opening 13, at which point the front side of the protective plate 22 is completely pressed against the outside of the ice scraper 6. This mechanical guiding structure ensures the liquid container 2 is installed in place and controls the fitting accuracy between the protective plate 22 and the ice scraper 6 through rigid contact.

[0038] The present invention further proposes that a material box 4 is provided on the frame 1, the bottom of the material box 4 is placed in the receiving cavity 11, and a discharge valve 41 is provided at the bottom of the material box 4; a rib 24 is provided on the liquid box 2, the rib 24 corresponds to the discharge valve 41, and when the liquid box 2 is installed in place, the rib 24 opens the discharge valve 41.

[0039] The material tank 4 is a container for storing liquid raw materials, and can be made of stainless steel or food-grade plastic. Its bottom is positioned within the receiving cavity 11, ensuring the discharge valve 41 is located at a crucial point in the insertion path of the liquid container 2. The discharge valve 41 is a switch device that controls the outflow of raw materials; it can be a spring-reset valve that remains closed when not triggered to prevent leakage. The rib 24 is a raised structure on the surface of the liquid container 2, and can be a plastic strip integrally molded with the container. Its height and position are calculated to ensure it only contacts and pushes open the discharge valve 41 when the liquid container 2 is fully inserted.

[0040] Specifically, the moment the liquid tank is fully installed, the protruding rib 24 pushes upward against the valve core of the discharge valve 41, forcing the valve to open and allowing the raw material in the material tank 4 to flow into the liquid tank 2. In this process, a mechanical interlock structure replaces the traditional solenoid valve control, avoiding the problem of electronic components being easily damaged by moisture or mis-triggered.

[0041] The present invention further proposes that the bottom of the front end of the receiving cavity 11 is provided with an inclined plate 14. When the liquid box 2 is inserted into the lower part of the receiving cavity 11, the front end of the liquid box is raised along the inclined plate so that the rib can open the material valve.

[0042] The inclined plate 14 refers to an inclined plane structure located at the bottom of the receiving cavity 11 near the inner end, which can be made of metal stamping or injection molding sheet metal. The inclined plate 14 guides the rear end of the liquid container 2 to generate vertical displacement during insertion through physical contact, thereby compensating for lateral installation errors. The lifting of the front end of the liquid container 2 along the inclined plate 14 means that after the bottom front end of the liquid container 2 contacts the inclined plate, it moves upward along the inclined surface of the inclined plate 14 under the push of the insertion action. This action converts horizontal thrust into vertical displacement, causing a height adjustment of the contact position between the rib 24 and the discharge valve 41.

[0043] Specifically, when the liquid container 2 is pushed into the receiving cavity 11, its front bottom first contacts the inclined surface of the ramp 14. As the insertion continues, the ramp surface generates an upward reaction force on the liquid container 2, forcing the front end of the liquid container to rise. At this time, the rib 24 fixed on the liquid container 2 changes height accordingly. When the liquid container 2 is fully inserted, the vertical position of the rib 24 is precisely adjusted to be directly below the discharge valve 41, and the valve is reliably opened by mechanical pressing. The inclination angle and length of the ramp 14 are calculated to ensure that the liquid container 2 completes the required height compensation within a limited stroke.

[0044] This utility model further proposes a technical solution of providing a handle 25 at the rear end of the liquid container 2 to facilitate the insertion and removal of the liquid container 2.

[0045] The rear end of the liquid container 2 refers to the end of the liquid container 2 closest to the user's operating direction. Specifically, it can be achieved by using an extension structure fixedly connected to the rear end face of the liquid container 2. This position facilitates the user to apply force during insertion and withdrawal. The handle 2 is the force-applying component used for gripping, making it easy for the fingers to grasp and transmit pushing or pulling forces.

[0046] The present invention further proposes that the liquid box 2 is provided with a discharge port 23, the discharge port 23 is located on the rear side of the protective sheet 22, and the frame 1 is provided with a cup 5, which is correspondingly arranged with the discharge port 23.

[0047] The discharge port 23 refers to the discharge channel on the liquid container 2, which is located behind the protective plate 22 and is used to guide the ice material to be discharged in a designated direction. The rear side of the protective plate 22 refers to the side of the protective plate 22 facing away from the ice scraper in the direction in which the liquid container 2 is inserted.

[0048] Specifically, when the liquid container 2 is inserted into the receiving cavity 11, the front side of the protective plate 22 is pressed tightly against the outer side of the ice scraper 6 to form a physical barrier, preventing the accumulation of ice on the outer side of the ice scraper 6 under low-temperature conditions. The discharge port 23 is located on the rear side of the protective plate, allowing the ice to be discharged directly through this channel after scraping, avoiding contact with the icing area on the outer side of the ice scraper 6. The cup 5 on the frame 1 is vertically aligned with the discharge port 23, and the ice falls freely into the cup 5 along the space behind the protective plate 22. There is no icing interference area in the transmission path, thereby eliminating the risk of secondary freezing of the ice due to contact with the outer side of the ice scraper 6 during the discharge process.

[0049] This utility model further proposes that a door body is installed on the opening.

[0050] The door 12 refers to the movable structure covering the opening 13, which can be implemented by a hinged door panel or a sliding door panel, and is used to close the opening 13 after the liquid box 2 is inserted.

[0051] Specifically, after the liquid container 2 is inserted into the receiving cavity 11, the door 12 is closed to cover the opening 13. A sealed space is formed between the door 12 and the frame 1, blocking the heat exchange between the cold air inside the receiving cavity 11 and the external environment. With the door 12 closed, the low-temperature environment generated by the evaporator 3 is confined within the receiving cavity, further reducing cold loss.

[0052] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims, and all of these forms are within the scope of protection of the present utility model.
