Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to an ice cream machine. Background Technology

[0002] An ice cream machine is a device that can quickly make frozen desserts such as ice cream and smoothies. It typically includes a refrigeration system, a stirring device, and a drive mechanism. The drive mechanism drives the stirring device to rotate at high speed, breaking down the ingredients and stirring them into a smooth, slushy consistency. Modern ice cream machines have multiple working components inside. Because each component is dependent on the machine casing, it generates significant vibrations during operation, making it unstable. Utility Model Content

[0003] The main purpose of this invention is to propose an ice cream machine that aims to solve the technical problem of excessive vibration during operation.

[0004] To achieve the above objectives, the support component proposed in this utility model includes: The outer casing has internal installation space. A support assembly is disposed within the installation space. The support assembly includes an upper rigid frame, a lower rigid frame, and a support shaft. The two ends of the support shaft are fixedly connected to the upper rigid frame and the lower rigid frame, respectively. The cutting tool is located on the support assembly; A cup holder, located on the support assembly, is used to mount the cup body assembly. The cup holder moves relative to the blade, and the rotation of the blade grinds the ice cubes inside the cup body assembly.

[0005] In one embodiment, the upper rigid frame and / or the lower rigid frame are configured as sheet metal frames.

[0006] In one embodiment, at least four support shafts are provided, and the ends of the support shafts are connected to the upper rigid frame and the lower rigid frame by fasteners.

[0007] In one embodiment, the inner wall of the housing is provided with at least one snap-fit ​​seat, and the side of the upper rigid frame is bent to provide a downwardly extending snap-fit ​​plate, which snaps into the snap-fit ​​seat.

[0008] In one embodiment, the ice cream machine further includes a first support rib, which is disposed on the side of the top plate of the outer casing facing the installation space, and the first support rib is used to abut against the upper rigid frame.

[0009] In one embodiment, the ice cream machine further includes a second support rib, which is disposed on the side of the outer casing bottom plate facing the installation space, and the second support rib is used to support the lower rigid frame.

[0010] In one embodiment, the ice cream machine further includes a first drive module, which is disposed on the upper rigid frame and drivenly connected to the cutter, and drives the cutter to rotate.

[0011] In one embodiment, the ice cream machine further includes a second drive module and a transmission module. The transmission module includes a worm gear, at least one of the support shafts is configured as a threaded shaft, the worm gear is threadedly connected to the threaded shaft, and the cup holder is rotatably connected to the worm gear. The fixed end of the second drive module is disposed on the cup holder, and the output end of the second drive module is drivenly connected to the worm gear. The second drive module drives the worm gear to rotate, so that the worm gear rises along the threaded shaft and drives the cup holder to rise.

[0012] In one embodiment, the transmission module further includes a drive rod with worm gears at both ends and a worm wheel at each end along the length of the drive rod. Each worm wheel is threadedly connected to a threaded shaft, and each worm gear is driven to the corresponding worm wheel. The second drive module drives the worm wheel to rotate via the drive rod and to move up and down along the threaded shaft.

[0013] In one embodiment, the worm gear has a first wheel portion and a second wheel portion coaxially arranged. The cross-section of the second wheel portion is smaller than the cross-sectional area of ​​the first wheel portion. The outer periphery of the first wheel portion has gear teeth that are threadedly connected to the worm. The inner wall of the second wheel portion has an internal thread that is threadedly connected to the threaded shaft. The cup seat is rotatably connected to the outer periphery of the second wheel portion through a bearing.

[0014] In this invention, the ice cream machine has a shell with an installation space inside. An upper rigid frame and a lower rigid frame are arranged horizontally and spaced apart within the installation space. A support shaft is positioned between the upper and lower rigid frames to support them. By internally installing the upper and lower rigid frames, the overall rigidity of the shell is improved. Specifically, the blade is mounted on the upper rigid frame, and the cup holder is movably mounted on the lower rigid frame. When the blade rotates and grinds the ice cubes inside the cup holder, the resulting shaking is absorbed by the internal upper and lower rigid frames, weakening the vibration energy transmitted to the shell. This reduces the shaking during machine operation and improves stability. Furthermore, since the blade and cup holder are no longer directly mounted on the shell, they no longer serve as direct support structures. The shell completely encloses the internal upper and lower rigid frames, blade, and cup holder, which also reduces internal operating noise. Attached Figure Description

[0022] This utility model proposes an ice cream machine.

[0023] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the ice cream machine includes: The outer casing is 100mm, and the interior has installation space. The support assembly 200 is located in the installation space. The support assembly 200 includes an upper rigid frame 210, a lower rigid frame 220 and a support shaft 230. The two ends of the support shaft 230 are fixedly connected to the upper rigid frame 210 and the lower rigid frame 220 respectively. The cutting tool 300 is mounted on the support assembly 200; The cup holder 400 is located on the support assembly 200 and is used to install the cup body assembly. The cup holder 400 moves relative to the blade 300, and the blade 300 rotates to grind the ice inside the cup body assembly.

[0024] In the technical solution of this utility model, the ice cream machine has a shell 100, and an installation space is formed inside the shell 100. An upper rigid frame 210 and a lower rigid frame 220 are arranged sequentially from top to bottom within the installation space. The upper rigid frame 210 and the lower rigid frame 220 are horizontally spaced apart. A support shaft 230 is arranged between the upper rigid frame 210 and the lower rigid frame 220 to support them. By arranging the upper rigid frame 210 and the lower rigid frame 220 internally, the overall rigidity of the shell 100 is improved, especially by mounting the blade 300 and the cup holder 400 on the support shaft. On component 200, and in relative motion, when the blade 300 moves into the cup body component on the cup holder 400 to rotate and grind the ice, the resulting shaking is absorbed by the internal upper rigid frame 210 and lower rigid frame 220, and the vibration energy transmitted to the outer shell 100 is weakened, thus reducing the shaking of the whole machine during operation and improving stability. In addition, since the blade 300 and cup holder 400 are no longer directly mounted on the outer shell 100, they no longer serve as direct support structures. The outer shell 100 completely covers the internal upper rigid frame 210, lower rigid frame 220, blade 300 and cup holder 400, which can also reduce the noise during internal operation.

[0025] The ice cream machine, as a refrigeration device, needs to thoroughly grind ice into slush during operation. The ice cream machine includes a casing 100 and an internal cup holder 400 and blades 300. The blades 300 are positioned above the cup holder 400. A cup assembly is located on top of the cup holder 400, with an opening at the top and a lid at the opening. Ice cubes or other food items are placed inside the cup assembly. The cup holder 400 moves towards the blades 300, allowing the blades 300 to pass through the lid. The rotation of the blades 300 causes them to grind inside the cup assembly. Specifically, the casing 100, as the external support component 200 of the ice cream machine, can be made of metal or plastic, without limitation. The casing 100 can be square or round, without limitation. A support pad, made of silicone, can be provided at the bottom of the casing 100. This not only increases the friction between the casing 100 and supports such as a tabletop, preventing movement during ice grinding, but also reduces internal shaking during operation. In this embodiment, the outer shell 100 has a square structure, while the upper rigid frame 210 and lower rigid frame 220 inside it have rectangular structures. The upper rigid frame 210 and lower rigid frame 220 are horizontally and spaced apart inside the outer shell 100. They can be made of rigid materials, or aluminum alloy, magnesium alloy, titanium alloy, or fiber-reinforced composite materials, which have high strength and can effectively absorb vibration when supporting the working device inside the outer shell 100, making the operation more stable. No limitation is made here. The upper rigid frame 210 and lower rigid frame 220 are connected by a support shaft 230. The support shaft 230 can be a stainless steel optical shaft, and its two ends can be connected to the upper rigid frame 210 and lower rigid frame 220 respectively by welding or riveting to form an integral spatial frame. No limitation is made here. When the cutter 300 and the cup holder 400 are installed on this spatial frame, they can effectively absorb the shaking caused by rotation and reduce the shaking of the outer shell 100.

[0026] In the embodiments of this utility model, the upper rigid frame 210 and / or the lower rigid frame 220 are configured as sheet metal frames. Sheet metal frames are high in strength and light in weight. They can be formed in one step by CNC punching, bending and laser welding, making them suitable for mass production. They are not only high in strength, but also have high production efficiency and high material utilization.

[0027] In an embodiment of this utility model, at least four support shafts 230 are provided, and the ends of the support shafts 230 are connected to the upper rigid frame 210 and the lower rigid frame 220 by fasteners 240. The four support shafts 230 correspond to the periphery of the upper rigid frame 210 and the lower rigid frame 220, respectively. A connecting hole 212 is provided at the location of the support shaft 230 on the upper rigid frame 210. An upper gasket 250 and a lower gasket 251 are respectively provided above and below the connecting hole 212. The upper outer periphery of the support shaft 230 is provided with... The support shaft 230 is threaded, and its upper end passes upward through the lower steel ring, the connecting hole 212, and the upper washer 250 in sequence. A fastener 240 is screwed onto the support shaft 230. The fastener 240 is configured as a nut, and the lower side of the nut abuts against the upper washer 250. This fastener locks the support shaft 230 while preventing damage to the upper rigid frame 210. The support shaft 230 and the upper rigid frame 210 are fixed by the nut. The connection between the lower rigid frame 220 and the support shaft 230 is similar and will not be described in detail here. In other embodiments, there may be 6, 8, 10, etc., support shafts 230, which is not limited here.

[0028] In one embodiment, the cross-section of the connecting hole 212 is "D" shaped. The upper part of the support shaft 230 includes a first end 231 and a second end. The cross-sectional shape of the first end 231 is the same as that of the connecting hole 212. The second end is located above the connecting hole 212 and its cross-section is smaller than that of the first end 231 so that the upper part of the second end can pass through the connecting hole 212. The outer periphery of the cross-section of the second end is circular, and the second end is provided with a thread for screwing with a nut. The first end 231 passes through the "D" shaped connecting hole 212. By engaging with the straight edge of the connecting hole 212, the support shaft 230 can be prevented from rotating in the connecting hole 212, ensuring the stability of the connection between the support shaft 230 and the upper rigid frame 210 and the lower rigid frame 220. The nut can prevent the upper rigid frame 210 from separating from the support shaft 230 in the vertical direction. Similarly, the connecting hole 212 on the lower rigid frame 220 is also "D" shaped to stably connect the lower rigid frame 220 and the support shaft 230.

[0029] In embodiments of this utility model, such as Figure 2 , Figure 4 and Figure 5As shown, the inner wall of the outer casing 100 is provided with at least one snap-fit ​​seat 110. The side of the upper rigid frame 210 is bent to provide a downwardly extending snap-fit ​​plate 211. The snap-fit ​​plate 211 snaps into the snap-fit ​​seat 110. The snap-fit ​​seat 110 includes a first seat body and a second seat body. The first seat body is provided on the inner wall of the outer casing 100 and extends away from the inner wall of the outer casing 100. The second seat body is fixed to the side of the first seat body away from the inner wall of the outer casing 100 and extends upward, so that a certain gap is formed between the second seat body and the inner wall of the outer casing 100. This gap is configured as a snap-fit ​​groove. The upper end and both sides of the snap-fit ​​groove are respectively formed with openings. The snap-fit ​​plate 211 is formed on the side of the upper rigid frame 210. 1. The snap-fit ​​plate 211 and the upper rigid frame 210 are integrally formed. The snap-fit ​​plate 211 and the upper rigid frame 210 are bent and extended downward, so that the connection between the snap-fit ​​plate 211 and the upper rigid frame 210 forms an "L" shaped cross section. The snap-fit ​​plate 211 is inserted downward into the snap-fit ​​groove, so that the bottom of the snap-fit ​​groove can limit the snap-fit ​​plate 211 and prevent the upper rigid frame 210 from falling off the snap-fit ​​seat 110. This connects the upper rigid frame 210 to the inner wall of the outer shell 100. The cooperation between the snap-fit ​​plate 211 and the snap-fit ​​seat 110 not only facilitates the connection between the upper rigid frame 210 and the outer shell 100, but also facilitates its disassembly and reconstruction so that it can be removed for repair or replacement when internal components are damaged.

[0030] In one embodiment, the second seat has an inclined surface at the end away from the first seat and on the side facing the snap-fit ​​groove, forming a guide portion to guide the snap-fit ​​plate 211 when it is inserted into the snap-fit ​​groove.

[0031] In embodiments of this utility model, such as Figure 1 As shown, the ice cream machine also includes a first support rib 120. The first support rib 120 is located on the side of the top plate of the outer shell 100 facing the installation space. The first support rib 120 is used to abut against the upper rigid frame 210. The first support rib 120 is made of steel or plastic. It is designed to be integrally formed with the top plate of the outer shell 100. The first support rib 120 extends downward from the top plate. When the snap-fit ​​plate 211 snaps into the snap-fit ​​seat 110, the bottom of the first support rib 120 abuts against the top of the upper rigid frame 210. This can prevent the upper rigid frame 210, the support shaft 230 and the lower rigid frame 220 from moving upward and disengaging from the snap-fit ​​seat 110. This improves the stability of the upper and lower support frame structures inside the outer shell 100, thereby improving the stability of the installation of the internal components of the entire outer shell 100 and reducing shaking and noise during processing.

[0032] In one embodiment, in order to improve the strength of the first support rib 120, the first support rib 120 includes a cylindrical portion and a protruding rib disposed on the outer periphery of the cylindrical portion and extending along the axial direction of the cylindrical portion. The number of the first support rib 120 is not limited and can be 4, 6 or 8, etc.

[0033] In embodiments of this utility model, such as Figure 1 As shown, the ice cream machine also includes a second support rib 130. The second support rib 130 is located on the side of the bottom plate of the outer casing 100 facing the installation space. The second support rib 130 is used to support the lower rigid frame 220. The second support rib 130 is made of steel or plastic and is designed to be integrally formed with the bottom plate of the outer casing 100. The second support rib 130 extends upward from the bottom plate and is used to support the lower rigid frame 220. This means that the arrangement of the first support rib 120 and the second support rib 130 can prevent the upper rigid frame 210, the support shaft 230 and the lower rigid frame 220 from moving upward to disengage from the snap-fit ​​seat 110, and can also prevent the lower rigid frame 220 from moving downward. This allows the upper rigid frame 210 and the lower rigid frame 220 to be precisely assembled between the first support rib 120 and the second support rib 130 and fixed between the first support rib 120 and the second support rib 130, further improving the stability of the assembly and reducing vibration during operation.

[0034] In embodiments of this utility model, such as Figure 2 As shown, the ice cream machine also includes a first drive module 500. The first drive module 500 is mounted on the upper rigid frame 210 and drivenly connected to the cutter 300. The first drive module 500 drives the cutter 300 to rotate. The first drive module 500 includes a first drive motor, which is mounted on the inner wall of the upper rigid frame 210 and the outer casing 100. Its output shaft passes upward through the upper rigid frame 210. A drive wheel and a driven wheel 520 are rotatably mounted above the upper rigid frame 210. The drive wheel and the driven wheel 520 are connected by a belt drive. The output shaft is coaxially connected to the drive wheel. The first drive motor drives the drive wheel to rotate through the output shaft and drives the driven wheel 520 to rotate through the belt. The drive shaft 510 is coaxially connected to the drive wheel 520. The drive shaft 510 passes downward through the upper rigid frame 210 and is rotatably connected to the upper rigid frame 210 through a bearing. The lower end of the drive shaft 510 is connected to the cutter 300 through a cutter shaft. When the driven wheel 520 rotates, it drives the cutter 300 to rotate through the drive shaft 510 and the cutter shaft, thereby causing the cutter 300 to grind the ice inside the cup holder 400. Since the first drive module 500, the drive wheel, the driven wheel 520 and the drive shaft 510 are all directly or indirectly mounted on the upper rigid frame 210, the vibration generated by the friction between the cutter 300 and the ice is absorbed by the upper rigid frame 210 when the cutter 300 is driven to rotate, reducing the vibration of the outer shell 100.

[0035] In embodiments of this utility model, such as Figure 2 and Figure 6As shown, the ice cream machine also includes a second drive module 600 and a transmission module. The transmission module includes a worm gear 610, at least one support shaft 230 is configured as a worm wheel, the worm gear 610 is threadedly connected to the threaded shaft, and the cup holder 400 is rotatably connected to the worm gear 610. The fixed end of the second drive module 600 is located on the cup holder 400, and the output end of the second drive module 600 is drivenly connected to the worm gear 610. The second drive module 600 drives the worm gear 610 to rotate, so that the worm gear 610 rises along the threaded shaft and drives the cup holder 400 to rise.

[0036] Specifically, the second drive module 600 uses a servo motor, which is installed at the bottom of the cup holder 400. A cup body assembly is installed at the top of the cup holder 400, and the cup body assembly is used to hold ice cubes awaiting food processing. Since the two ends of the support shaft 230 are connected to the upper rigid frame 210 and the lower rigid frame 220 respectively, the support shaft 230 near the cup holder 400 is configured as a threaded shaft, with threads on its outer circumference for threaded connection with the worm gear 610. When the worm gear 610 rotates, it can synchronously rise and fall along the threaded shaft. Figure 6 As shown, the worm gear 610 is mounted on the cup holder 400 and rotatably connected to the cup holder 400. When the second drive module 600 drives the worm gear 610 to rotate, causing the worm gear 610 to rise along the threaded shaft, it drives the cup holder 400 and the cup body assembly mounted on the cup holder 400 to rise together. This allows the cutter 300 to enter the interior of the cup body assembly, so that the rotation of the cutter 300 can grind the ice inside the cup body assembly. That is, the support shaft 230 can not only support the upper rigid frame 210 and the lower rigid frame 220, but also serve as the threaded shaft for the worm gear 610 to rise and fall, reducing the transmission structure inside the outer shell 100, reducing the weight of the whole machine, and further absorbing the vibration generated by the rotation of the cutter 300 inside the cup body assembly, thus reducing the vibration of the outer shell 100.

[0037] In one embodiment, such as Figure 2 and Figure 6 As shown, the transmission module also includes a drive rod 620, with worm gears 630 at both ends of the drive rod 620. A worm wheel 610 is provided at each end of the drive rod 620 along its length. Each worm wheel 610 is threadedly connected to a threaded shaft. Each worm gear 630 is drivenly connected to the corresponding worm wheel 610. The second drive module 600 drives the worm wheel 610 to rotate through the drive rod 620 and moves it up and down along the threaded shaft.

[0038] Referring to the diagram, the drive rod 620 is horizontally positioned, with a worm gear 630 coaxially mounted at each end. The second drive module 600 is connected to the drive rod 620 via a reducer, causing the drive rod 620 to rotate, which in turn drives the worm gear 630 to rotate. The worm gear 630 engages with the thread, and as it rotates, it drives the worm wheel 610 to rotate and rise along the threaded shaft, thereby causing the cup holder 400 and the cup body assembly to rise. Since the second drive module 600 is fixedly mounted on the cup holder 400, it rises synchronously. By setting worm gears 630 at both ends of the drive rod 620, the horizontal rotation is converted into vertical movement. The worm wheels 610 at both ends of the worm gear 630 cooperate with it, making the lifting and lowering more stable and preventing deviation during the lifting and lowering process.

[0039] In one embodiment, the worm gear 610 has a first wheel portion and a second wheel portion coaxially arranged. The cross-section of the second wheel portion is smaller than the cross-sectional area of ​​the first wheel portion. The outer periphery of the first wheel portion has gear teeth that are threadedly connected to the worm 630. The inner wall of the second wheel portion has an internal thread that is threadedly connected to the threaded shaft. The cup seat 400 is rotatably connected to the outer periphery of the second wheel portion through a bearing.

[0040] Please refer to Figure 2 A movable hole 410 is provided on each side of the cup holder 400. The second wheel of the worm gear 610 extends upward into the movable hole 410 and is rotatably connected to the cup holder 400 through a bearing in the movable hole 410. When the worm 630 drives the worm gear 610 to rotate, the second wheel rotates in the movable hole 410. Since the cross-sectional area of ​​the first wheel is larger than the cross-sectional area of ​​the connecting hole 212 of the cup holder 400, when the worm gear 610 rises, the first wheel pushes the cup holder 400 upward, which will drive the cup holder 400 to rise, so that the tool 300 can enter the cup body assembly to grind the inside of the cup body assembly.

[0041] In one embodiment, a sleeve 640 is provided in the movable hole 410. The sleeve 640 is sleeved on the outer periphery of the second wheel. The bottom of the sleeve 640 is located outside the connecting hole 212 and is larger than the cross-sectional area of ​​the connecting hole 212. The bottom of the sleeve 640 is fixedly connected to the first wheel. The sleeve 640 is connected to the movable hole 410 in the movable hole 410 through a bearing. When the worm 630 rotates and drives the worm wheel 610 to rotate and rise, the sleeve 640 rotates in the movable hole 410 and pushes the cup holder 400 to rise. When the worm wheel 610 rotates in the opposite direction and falls, the sleeve 640 drives the cup holder 400 to fall through the bearing, thus completing the engagement and disengagement of the cup holder 400 and the cutter 300.

[0042] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
