Description

Technical Field

[0001] The utility model relates to the technical field of slushy ice machines, in particular to a novel ice-making device and a slushy ice machine. Background Art

[0002] In modern life, people often use shavings and ice desserts to enjoy. When making shavings, the shaving ice machine mainly keeps the ice-making roller at a relatively low temperature, so that the temperature of the liquid raw material attached to the roller can be quickly reduced, and condensed into ice attached to the ice-making roller, and the ice is scraped off with the help of a scraper to form shavings. Since the ice-making roller is always in a low-temperature environment, and the ice-making roller will always be attached to the liquid raw material when it rotates, the liquid raw material has strong fluidity, and it is not only easy to stick to the surface of the ice-making roller, but also easy to stick to the edges on the left and right sides of the ice-making roller. The scraper is mainly used to scrape off the ice on the surface of the ice-making roller, and cannot handle the ice attached to the edges on the left and right sides of the ice-making roller. Over time, the ice layer on the edges on both sides will accumulate thicker and thicker. As time goes by, the ice layer will become harder and harder, and it is also quite troublesome to disassemble and clean the machine, and it will also have a certain impact on the subsequent production of shavings. Therefore, it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Example 1

[0042] See also Figures 1 to 19 The utility model discloses a novel ice-making device, comprising a frame 1, an ice-making roller 2 located inside the frame 1, a roller driving mechanism 3 for driving the ice-making roller 2 to rotate forward or reversely, a first scraper 4 located at the front side of the ice-making roller 2, and a collecting tray 5 arranged below the ice-making roller 2, wherein the collecting tray 5 contains raw materials, which can be attached to the surface of the ice-making roller 2, and the first scraper 4 is connected to the frame 1; when in use, raw materials are added to the collecting tray 5, and the raw materials are preferably water, or pre-mixed liquids with different flavors; when working, the ice-making roller The roller driving mechanism 3 is driven to circulate and rotate. When the surface of the ice-making roller 2 passes over the collecting plate 5, the raw materials are attached to the surface. Under the action of low temperature, the raw materials are rapidly cooled and condensed into thin ice attached to the ice-making roller 2. The first scraper 4 located at the front side of the ice-making roller 2 can continuously scrape off the thin ice attached to the surface of the ice-making roller 2. The process of the thin ice being scraped off and falling down forms shaved ice, thereby completing the work of making shaved ice. The roller driving mechanism 3 also includes at least two side scrapers 6, which are respectively arranged on the left and right sides of the ice-making roller 2. The side scrapers 6 are used to scrape off the ice on the left and right sides of the ice-making roller 2.

[0043] See also Figure 1Specifically, the side scraper 6 is connected to the first scraping part 4, so that when the first scraping part 4 scrapes the ice on the surface of the ice-making roller 2, the side scraper 6 can simultaneously scrape the ice on the left and right sides of the ice-making roller 2 to prevent the ice layers on the left and right sides from accumulating, and the scraped ice cubes fall into the collecting tray 5 and merge with the raw materials for subsequent ice making;

[0044] Example 2

[0045] See also Figure 2 As another preferred embodiment, two side scrapers 6 are connected to the frame 1 through a first connection portion 601; specifically, the number of first connection portions 601 is two, and a single side scraper 6 is connected to the frame 1 through a single first connection portion 601; preferably, the side scraper 6 is arranged above the rear side of the ice-making roller 2, and during the rotation of the ice-making roller 2, the side scraper 6 synchronously scrapes the ice on the left and right sides of the ice-making roller 2, and the scraped ice cubes fall into the collecting tray 5 and merge with the raw materials for subsequent ice making. This structure can also prevent the accumulation of ice on the left and right sides of the ice-making roller 2.

[0046] Example 3

[0047] See also Figure 3 As another preferred embodiment, the number of side scrapers 6 is 2, the number of first connection part 601 is 1, the two side scrapers 6 are respectively located on the left and right sides of the ice-making roller 2, and are fixed to the frame 1 through the first connection part 601; as a preferred embodiment, the two side scrapers 6 and the first connection part 601 are an integrated structure, so that the side scrapers 6 located on the left and right sides of the ice-making roller 2 are used to synchronously scrape off the ice on the left and right sides of the ice-making roller 2 during operation. This solution has a simple structure and is easy to install during actual production.

[0048] After making a portion of shaved ice dessert, even if the ice-making roller 2 stops rotating, the surface of the ice-making roller 2 is still stained with liquid raw materials. Since the ice-making roller 2 is always in a low-temperature environment, the residual liquid raw materials will continue to condense into ice on the ice-making roller 2 and adhere to its surface. After performing ice-making operations for many times, the ice layer on the ice-making roller 2 will become thicker and thicker due to the aforementioned accumulation. Over time, the ice layer will become harder and harder, and even affect the effect of the subsequent scraper on scraping the ice on the surface of the ice-making roller 2. Problems such as scraping off flaky ice or the ice layer being too hard to scrape will occur, affecting the making of shaved ice desserts. Cleaning the ice-making roller 2 requires chiseling the ice layer, which cannot ensure hygiene and is quite troublesome. In addition, it will also have a certain impact on the subsequent making of shaved ice.

[0049] Example 4

[0050] Therefore, in order to prevent ice from accumulating on the surface of the ice-making roller 2, the ice-making roller 2 further includes a second scraper 7 and a telescopic device 8. The second scraper 7 and the first scraper 4 are respectively located at two opposite sides of the ice-making roller 2. The telescopic device 8 is used to drive the second scraper 7 to approach or move away from the ice-making roller 2. Figure 4-5 In the process of making shaved ice drinks, the telescopic device 8 drives the second scraper 7 away from the ice-making roller 2 to avoid affecting the first scraper 4 from scraping the ice-making roller 2 to make shaved ice; see Figure 7-8 When the shaved ice drink is prepared, the roller driving mechanism 3 drives the ice-making roller 2 to continue to rotate forward, and the telescopic device 8 drives the second scraper 7 to approach the ice-making roller 2 to scrape the ice from the ice-making roller 2. This can scrape off the excess ice on the surface of the ice-making roller 2 and control the thickness of the ice layer on the surface of the ice-making roller 2 to a minimum value, thereby preventing the ice layer from accumulating too thickly. The scraped ice falls into the collecting tray 5 and merges with the raw materials for subsequent ice making.

[0051] See also Figure 5-8 Specifically, it also includes a support rod 11 and a second connection part 12. The frame body 1 is provided with a first opening 101, and the support rod 11 is arranged on the outer side of the frame body 1. The telescopic device 8 includes an elastic member 801, a pull rod 802 and a telescopic driving mechanism 803. The second connection part 12 passes through the first opening 101 to connect the second scraping part 7 and the pull rod 802. One end of the elastic member 801 is connected to the support rod 11 and the other end is connected to the second connection part 12. The telescopic driving mechanism 803 is connected to the pull rod 802. Preferably, both ends of the elastic member 801 are provided with connecting rings, which are respectively sleeved on the support rod 11 and the second connection part 12. Further preferably, the above structure has two groups, which are respectively arranged on the left and right sides of the frame body 1, that is, respectively located on the left and right sides of the second scraping part 7. This structure can have a better pulling balance when controlling the second scraping part 7. During the process of making smoothie drinks, the telescopic driving mechanism 803 pulls the pull rod 802, and then pulls the second connecting part 12 to drive the second scraper 7 to move away from the ice-making roller 2, so as to prevent the second scraper 7 from contacting the ice-making roller 2 and affecting the making of smoothies. At the same time, the elastic member 801 is extended under the drive of the second connecting part 12, so as to buffer the impact of the pull rod 802 driving the second scraper 7 to move; when the second scraper 7 is needed to scrape the surface of the ice-making roller 2, the roller driving mechanism 3 drives the ice-making roller 2 to continue to rotate forward, and the telescopic driving mechanism 803 stops pulling the pull rod 802. At this time, the pull rod 802 and the elastic member 801 are not subjected to external force, and the elastic member 801 will automatically retract without the pull of external force, which can drive the second connecting part 12 to move, and then drive the second scraper 7 to move towards the surface of the ice-making roller 2 to scrape the ice of the ice-making roller 2.

[0052] Preferably, the elastic member 801 is a spring.

[0053] Furthermore, it also includes a rotating shaft 13 and a rotating plate 14, the rotating shaft 13 is connected to the inner side of the frame 1, the rotating plate 14 is rotatably connected to the rotating shaft 13, the second scraper 7 is connected to the rotating plate 14, and the rotating plate 14 is connected to the pull rod 802 through the second connecting portion 12. In this embodiment, when it is necessary to make a smoothie drink, the telescopic driving mechanism 803 pulls the pull rod 802, and then pulls the second connecting portion 12 to drive the rotating plate 14 and the second scraper 7 to move away from the ice-making roller 2, and the rotating shaft 13 is fixed to the frame 1, and the rotating plate 14 can rotate along the rotating shaft 13, so that the rotating plate 14 drives the second scraper 7 to stay within the limited moving range in the process of approaching or moving away from the ice-making roller 2, which improves the stability of the machine when it is used, and on the other hand, it can also improve the distance accuracy of the second scraper 7 to the surface of the ice-making roller 2 in the actual process of scraping ice, so as to facilitate efficient and high-quality scraping of excess ice, improve the use effect of the equipment, and extend the service life of the equipment.

[0054] Furthermore, the first connection portion 601 is connected to the rotating plate 14. Preferably, the first connection portion 601 is located above the second scraping portion 7, and the side scrapers 6 are located on the left and right sides of the ice-making roller 2. This structure facilitates the side scrapers 6 to synchronously scrape off the ice on the left and right sides of the ice-making roller 2.

[0055] Furthermore, it also includes a fixing plate 102 , which is arranged on the outside of the frame 1 , and the support rod 11 is fixed on the fixing plate 102 . The fixing plate 102 is used to fix the support rod 11 on the frame 1 .

[0056] Furthermore, an adjusting member 24 is included, and the adjusting member 24 sequentially fixes the pull rod 802 and the elastic member 801 on the second connecting portion 12 from the outside to the inside.

[0057] Example 5

[0058] See also Figure 9-13 , including a third scraper 9 arranged on the outer side of the lower half surface of the ice-making roller 2, and the horizontal height of the third scraper 9 is higher than the height of the raw material; specifically, when the third scraper 9 is located on one side of the ice-making roller 2 where the first scraper 4 is located, the horizontal height of the third scraper 9 is lower than the horizontal height of the first scraper 4.

[0059] See also Fig.11 Further, the third scraper 9 includes a third scraper 901 and a plurality of third connecting parts 902, the third connecting part 902 connects the third scraper 901 and the collecting tray, or the third connecting part 902 connects the third scraper 901 and the frame 1, which can fix the position of the third scraper 9.

[0060] This embodiment is used to scrape ice from the surface of the ice roller after making shaved ice. During the process of making shaved ice drinks, the ice roller 2 rotates forward, and the first scraper 4 scrapes the ice on the surface of the ice roller 2 to form shaved ice, and the third scraper 9 will not affect the ice on the surface of the ice roller 2; when the shaved ice drink is prepared, the roller drive mechanism 3 drives the ice roller 2 to rotate in the reverse direction, so that the ice on the surface of the ice roller 2 can be scraped off by the third scraper 9 and dropped into the collection tray 5 for recycling raw materials. Similarly, the first scraper 4 will not affect the shaved ice.

[0061] See also Fig.12 In the present embodiment, the preferred structural mode is that the third scraper 9 is located on one side of the ice-making roller 2 where the first scraper 4 is located, and the level of the third scraper 9 is located between the level of the raw material and the level of the first scraper 4.

[0062] When making smoothies, the roller driving mechanism 3 drives the ice-making roller 2 to rotate forwardly, and the surface of the ice-making roller 2 is adhered to the raw materials when passing through the collecting tray 5. When the surface part adhered to the raw materials reaches the intersection with the first scraper 4, the ice on its surface can be scraped off by the first scraper 4, and the third scraper 9 is located between the first scraper 4 and the raw materials, and will not affect the ice scraping by the first scraper 4; when it is necessary to shave off the excess ice, the roller driving mechanism 3 drives the ice-making roller 2 to rotate reversely, and the raw materials adhered to the surface of the ice-making roller 2 can be shaved off by the third scraper 901 and fall into the collecting tray 5, so that the thickness of the ice layer on the surface of the ice-making roller 2 is kept controlled at a minimum value. Afterwards, the surface from which the excess ice has been shaved will not be affected by the first scraper 4 when passing through the first scraper 4. This can prevent the ice layer from accumulating too thickly, and the scraped ice falls into the collecting tray 5 and merges with the raw materials for subsequent ice making.

[0063] Example 6

[0064] See also Fig.14, including a fourth scraper 10, the fourth scraper 10 is arranged on the inner side of the first scraper 4, the blade head of the fourth scraper 10 extends toward the direction of the ice-making roller 2, and the blade head of the fourth scraper 10 is located above the inner side of the collecting tray and higher than the height of the raw materials. In this embodiment, the working principle of making shaved ice is the same as that of embodiment 2, and will not be repeated here; when it is necessary to shave off the excess ice, the roller driving mechanism 3 drives the ice-making roller 2 to rotate in the opposite direction, and the raw materials attached to the surface of the ice-making roller 2 can be shaved off by the fourth scraper 10 and fall into the collecting tray 5, so that the thickness of the ice layer on the surface of the ice-making roller 2 is kept at a minimum value, and then, when the surface from which the excess ice is shaved passes through the first scraper 4, it will not be affected by the first scraper 4, which can prevent the ice layer from accumulating too thickly, and the scraped ice falls into the collecting tray 5 and merges with the raw materials for subsequent ice making. The difference between this embodiment and embodiment 2 is that the third scraper 9 of embodiment 2 can be a component installed separately on the structure, while the fourth scraper 10 in this embodiment is arranged on the inner side of the first scraper 4, and can perform subsequent cleaning work without affecting the operation of the first scraper 4.

[0065] refer to Fig.15 Further, the roller driving mechanism 3 includes a driving motor 301 and a hollow rotating shaft 302, one end of the hollow rotating shaft 302 is drivingly connected to the output shaft of the driving motor 301, and the other end of the hollow rotating shaft 302 is connected to the ice-making roller 2; it also includes a temperature sensor 15 arranged in the inner cavity of the ice-making roller 2, a wire 17 is arranged in the hollow rotating shaft 302, one end of the wire 17 is connected to the temperature sensor 15, and the other end extends out of the hollow rotating shaft 302 and is rotatably connected to the wireless power supply component. The wireless power supply component is used to supply power to the temperature sensor 15. Since the wire 17 connected to the temperature sensor 15 is arranged in the hollow rotating shaft 302, and the wire 17 is rotatably connected to the wireless power supply component, the wireless power supply component is fixedly arranged. When the wire 17 and the temperature sensor 15 rotate with the hollow rotating shaft 302, the wireless power supply component remains stationary, which can avoid the problem of the wire 17 being entangled and torn off, thereby maintaining the stability of the line power supply and the stable transmission of the temperature monitor signal.

The conductive ring 18 and the carbon brush 19 solve the problem of providing power to the temperature sensor 15 during the rotation process. When the wire 17 rotates, the conductive ring 18 remains stationary to avoid the problem of the wire 17 being entangled due to the rotation, and at the same time, the effect of non-interference between the rotation of the hollow shaft 302 and the power provided by the temperature sensor 15 is achieved. The temperature sensor 15 rotates with the hollow shaft 302 and the ice-making roller 2. The temperature sensor 15 detects the temperature of the inner cavity of the rotating ice-making roller 2 in real time, and realizes that the temperature sensor 15, the conductive ring 18, and the carbon brush 19 can also continuously supply power when they are in a relative rotation state.

The high-temperature and high-pressure refrigerant gas output by the compressor 1601 is input into the condenser 1602, condensed by the condenser 1602 to become liquid, and then input into the inner cavity of the ice-making roller 2 along the outlet 303 of the condenser 1602; the ice-making roller 2 acts as an evaporator, outputs cold energy, and the liquid raw material in contact with it is condensed into ice due to heat absorption, so that the ice-making roller 2 can have the function of making ice.

[0072] See also Figure 17-18 As a preferred embodiment 2, this embodiment provides another wireless power supply component, which includes a transmitting coil 20, a receiving coil 21 that is electromagnetically induced with the transmitting coil 20, and a wireless transmitting module 22. The wire 17 passes through the transmitting coil 20 and the receiving coil 21 in sequence and is electrically connected to the wireless transmitting module 22. The receiving coil 21 is electrically connected to the wireless transmitting module 22. The wireless transmitting module 22 is wirelessly connected to the control module. By setting the receiving coil 21, electromagnetic induction can be achieved between the transmitting coil 20, thereby realizing wireless power supply to the wireless transmitting module 22, and then power is supplied to the temperature sensor 15 through the wireless transmitting module 22. The setting of the wireless transmitting module 22 can wirelessly transmit the temperature signal of the temperature sensor 15 to the control module, without setting the wire 17 connecting the wireless power supply component and the control module, which can reduce the setting of the line and simplify the structure of the smoothie machine.

[0073] As a preferred embodiment 3, in this embodiment, the setting position of the temperature sensor 15 is different from that of the preferred embodiment 1, see Fig.19 The end of the hollow shaft 302 close to the ice-making roller 2 is coaxially provided with a connecting tube 23, the connecting tube 23 is communicated with the inner cavity of the hollow shaft 302, the sealing end of the connecting tube 23 extends into the ice-making roller 2, and the temperature sensor 15 is located in the connecting tube 23. The connecting tube 23 is coaxially arranged with the hollow shaft 302, and the connecting tube 23 is used to accommodate the temperature sensor 15, and the connecting tube 23 extends into the ice-making roller 2 to contact the refrigerant in the inner cavity of the ice-making roller 2, so that the temperature sensor 15 can detect the temperature in the ice-making roller 2 through the connecting tube 23. In this arrangement, there is no need to open the surface of the hollow shaft 302, which reduces the difficulty of processing the hollow shaft 302, and the end of the wire 17 connected to the temperature sensor 15 does not need to be partially exposed to the environment, so as to avoid the user's accidental touch and affect the stability of temperature measurement.
