Description

[0002] The existing cold drink machine stores ice materials in a storage container and cools or insulates the storage container by a refrigeration device. When the storage container needs to output materials, the materials are pushed out to the outside by an internal discharge mechanism. Since the temperature of the materials when being output is close to the storage temperature, the discharge mechanism cannot output all the materials at one time, and thus part of the materials remains at the position of the discharge outlet. Since the storage temperature is close to the discharge temperature, the remaining materials are difficult to be cleaned at the storage temperature, and thus are accumulated in a body after a long time and hinder the output of subsequent materials, thereby affecting the discharge efficiency of the storage container.

[0040] As shown in FIGS. 1-5, an ice outlet structure for preventing ice condensation at the ice outlet includes an ice storage container 1 and a refrigeration mechanism 2.

[0041] The ice storage container 1 includes an ice storage shell 11 and an ice outlet cover 12.

[0042] The ice outlet cover 12 is mounted on the ice storage shell 11, and the ice storage shell 11 is provided with an ice storage cavity 111, and a refrigeration end of the refrigeration mechanism 2 is attached to an outer side wall of the ice storage cavity 111.

[0043] The ice outlet cover 12 is provided with an ice outlet cavity 121, and the ice storage cavity 111 is horizontally connected to the ice outlet cavity 121, and the ice outlet cavity 121 is used to receive the material of the ice storage cavity 111, and the ice outlet cavity 121 is provided with an ice outlet 122.

[0044] The wall thickness a of the ice outlet cover 12 at the ice outlet cavity 121 is greater than the wall thickness b of the ice storage shell 11 at the ice storage cavity 111.

[0045] The present application provides an ice outlet structure for preventing ice condensation at the ice outlet, which mainly includes an ice storage container 1 provided with an ice storage shell 11 and an ice outlet cover 12 with different thicknesses, and a refrigeration end of a refrigeration mechanism 2 is attached to an outer side wall of the ice storage shell 11, the ice storage shell 11 with small thickness facilitates refrigeration, and the ice outlet cover 12 with large thickness can increase the temperature difference between the ice outlet cavity 121 and the ice storage cavity 111, thereby solving the problem of insufficient flowability of the existing ice outlet machine when maintaining a single temperature for ice outlet, which causes residual and blockage at the ice outlet 122.

[0046] Specifically, the ice storage container 1 of the present solution comprises an ice storage shell 11 and an ice outlet cover 12; the ice storage shell 11 and the ice outlet cover 12 can be integrally combined and formed, or can be detachably connected to each other; the ice storage shell 11 is provided with an ice storage cavity 111, which is a main ice storage area corresponding to an existing ice outlet machine; and an outer side wall of the ice storage shell 11 is provided with a refrigeration end of a refrigeration mechanism 2, which has a refrigeration function and can reduce the temperature of the outer side wall of the ice storage cavity 111, so as to keep the inside of the ice storage cavity 111 in a low-temperature state, thereby meeting the storage temperature of the material; the ice outlet cover 12 is provided with an ice outlet cavity 121, and the ice outlet cavity 121 is further provided with an ice outlet opening 122; the ice outlet cavity 121 can be used to receive the material in the ice storage cavity 111, and the material can be output to the outside through the ice outlet opening 122, thereby completing ice outlet; in the present solution, the wall thickness refers to the distance between the outer side wall and the inner side wall; and in the present solution, as shown in FIG. 3, the wall thickness a of the ice outlet cavity 121 is greater than the wall thickness b of the ice storage cavity 111, the wall thickness b of the ice storage cavity 111 is smaller, and the refrigeration end of the refrigeration mechanism 2 is attached to the outer side wall of the ice storage cavity 111; the refrigeration effect of the refrigeration mechanism 2 on the ice storage cavity 111 is improved; and the outer side of the ice outlet cavity 121 is not provided with the refrigeration mechanism 2, but mainly contacts air or other structures; the air is distributed around the outer side wall of the ice outlet cavity 121, so that the air heats the inside of the ice outlet cavity 121 through the outer side wall of the ice outlet cavity 121, thereby slightly increasing the temperature of the ice outlet cavity 121; and the ingenious part of the present solution is that the wall thickness a of the ice outlet cavity 121 is designed to be greater than the wall thickness b of the ice storage cavity 111, that is, although the air can increase the temperature of the ice outlet cavity 121, the greater the wall thickness of the ice outlet cavity 121, the better the heat insulation effect, and thus the smaller the temperature change rate per unit time; in this way, the temperature of the material will decrease when passing through the ice outlet cavity 121, but the temperature is only slightly lower than that of the ice storage cavity 111, that is, the temperature will not decrease sharply in the ice outlet cavity 121; obviously, the material has a better refrigeration effect in the ice storage cavity 111, and the temperature of the ice outlet cavity 121 decreases, but the decrease rate is not too large; therefore, the present solution can control the wall thickness a of the ice outlet cavity 121 to make the temperature of the material slightly lower than the freezing point of the material, so that a small part of the material is melted, the material is in a solid-liquid coexistence state, the flowability of the material is increased, the material has a certain flowability, and the material is more easily discharged from the ice outlet opening 122, the residual amount of the material in the ice outlet opening 122 is reduced, the situation that the material is insufficient in flowability due to the too low temperature of the ice outlet machine and is residual and blocked in the ice outlet opening 122 is avoided, and the situation that the temperature is too high during ice outlet and the ice outlet amount is reduced and the material is residual in the ice outlet opening 122 is also avoided.

[0047] The refrigeration mechanism 2 is a known mechanism having a refrigeration function, such as a semiconductor refrigeration device, a liquid nitrogen refrigeration device, etc.

[0048] Optimally, the ice storage container 1 further comprises a fixing flange 13.

[0049] The inner ring of the fixed flange 13 is fixed to the outside of the ice storage shell 11 and located at the opening of the ice storage cavity 111; the opening of the ice outlet cavity 121 is threadedly matched to the outer ring of the fixed flange 13.

[0050] The ice storage container 1 of the present scheme preferably adopts a split structure; since the present scheme controls the temperature difference between the ice storage cavity 111 and the ice outlet cavity 121 based on the thickness of the ice outlet cover 12, the present scheme uses a threaded matching method to install the ice outlet cavity 121 on the outer ring of the fixed flange 13, which can realize quick installation and disassembly of the ice outlet cover 12, and can determine the optimal thickness of the ice outlet cover 12 according to the need of frequent installation and disassembly, thereby ensuring the optimal discharge temperature of the material in the ice outlet cavity 121.

[0051] Optimally, it further comprises a heat preservation shell 3.

[0052] The heat preservation shell 3 is provided with a heat preservation cavity 31, and the ice storage cavity 111 is located in the heat preservation cavity 31; the inner wall of the heat preservation cavity 31 forms a heat preservation distance c with the refrigeration end of the refrigeration mechanism 2.

[0053] As shown in FIG. 1, the heat preservation cavity 31 provided by the heat preservation shell 3 surrounds the ice storage cavity 111, which can seal and cover the refrigeration end of the refrigeration mechanism 2, so that the ice storage cavity 111 and its refrigeration mechanism 2 are located in an independent space; and the refrigeration end of the refrigeration mechanism 2 is away from the inner wall of the heat preservation cavity 31, and the heat preservation distance c formed between the two can avoid the influence of the external environment on the refrigeration effect of the ice storage cavity 111. The refrigeration end of the refrigeration mechanism 2 can be provided with a refrigeration pipe 21, which can be connected to a refrigeration medium, and the heat of the ice storage cavity 111 can be taken away through the refrigeration pipe 21, so as to keep the ice storage cavity 111 in a low-temperature state.

[0054] Optimally, the opening of the ice storage cavity 111 is located outside the heat preservation cavity 31, and the fixed flange 13 is exposed outside the heat preservation cavity 31.

[0055] The heat preservation cavity 31 mainly preserves the main body of the ice storage cavity 111, and the opening of the ice storage cavity 111 extends outside the heat preservation cavity 31, mainly to expose the fixed flange 13 outside the heat preservation cavity 31, so as to facilitate the threaded matching with the ice outlet cavity 121, thereby quickly installing and disassembling the ice outlet cover 12, while maintaining the refrigeration effect of the ice storage cavity 111. The ice storage cavity 111 of the present scheme is provided with a fixed flange 13 at the opening, which is equivalent to increasing the wall thickness of the ice storage cavity 111 at the opening, so that the temperature influence of the opening exposed outside the heat preservation cavity 31 is not great.

[0056] Optimally, the width between the inner ring and the outer ring of the fixed flange 13 is greater than the wall thickness a of the ice outlet cover 12 in the ice outlet cavity 121.

[0057] In the optimal embodiment, since the opening of the ice storage cavity 111 is located outside the heat preservation cavity 31, the opening of the ice storage cavity 111 is provided with the fixing flange 13, so the width between the inner ring and the outer ring of the fixing flange 13 can be greater than the thickness a of the wall of the ice outlet cavity 121 of the ice outlet cover 12, because the fixing flange 13 can effectively increase the thickness of the opening wall of the ice storage cavity 111, so that the temperature of the material in the ice storage cavity 111 can be kept unchanged, and the opening of the ice storage cavity 111 does not need to be thickened during processing, and the ice outlet cover 12 can be quickly installed and removed.

[0058] Optimally, the ice outlet 122 is arranged on the bottom wall of the ice outlet cavity 121 and is away from the opening of the ice outlet cavity 121; the side wall of the ice outlet cavity 121 gradually moves away from the center of the ice outlet cavity 121 from the bottom wall to the opening, so that the side wall of the ice outlet cavity 121 extends obliquely to the opening of the ice storage cavity 111.

[0059] In the optimal embodiment, the side wall of the ice outlet cavity 121 is a straight line type side wall with zero inclination;

[0060] As shown in FIG. 4, in the optimal embodiment, the side wall of the ice outlet cavity 121 has a certain inclination angle; specifically, the horizontal one end of the ice outlet cavity 121 is the opening, and the other horizontal end is the bottom wall; the ice outlet 122 is arranged on the bottom wall of the ice outlet cavity 121, that is, the ice outlet 122 is horizontally away from the opening of the ice outlet cavity 121; when the opening of the ice outlet cavity 121 receives the material in the ice storage cavity 111, the material needs to move along the side wall of the ice outlet cavity 121 and then be output to the ice outlet 122; the side wall of the ice outlet cavity 121 gradually moves away from the center of the ice outlet cavity 121 from the bottom wall to the opening, that is, the side wall of the ice outlet cavity 121 is farthest away from the center of the ice outlet cavity 121 near the opening and is closest to the center of the ice outlet cavity 121 at the bottom wall; in this way, the side wall of the ice outlet cavity 121 extends obliquely, as shown in FIG. 4, the side wall of the ice outlet cavity 121 extends obliquely upward from the opening of the ice storage cavity 111 to the ice outlet 122; according to this structure, the material will be output obliquely upward along the side wall of the ice outlet cavity 121 when the material is discharged, and the side wall of the ice outlet cavity 121 can slow down the movement of the material, so that the material stays in the side wall of the ice outlet cavity 121 for a longer time, and the local melting of the material can be output to the ice outlet 122; when the ice outlet structure is completed, the material has stayed in the side wall of the ice outlet cavity 121 for a long enough time, and the material will melt for a longer time and have more liquid part, so that the material can flow back along the side wall of the ice outlet cavity 121, thereby accelerating the time of the material flowing back to the ice storage cavity 111, so that the material returns to the ice storage cavity 111; thus, the side wall inclination angle of the ice outlet cavity 121 is ingeniously used to improve the discharging and returning efficiency.

[0061] Optimally, the ice storage device further comprises a spiral stirring paddle 4;

[0062] The spiral stirring paddle 4 is rotatably installed in the ice storage container 1 and located between the ice storage cavity 111 and the ice outlet cavity 121; the spiral stirring paddle 4 is used to transfer materials between the ice storage cavity 111 and the ice outlet cavity 121.

[0063] The spiral stirring paddle 4 is rotatably installed in the ice storage container 1 and mainly driven by a mechanism with a known driving rotation function, such as a motor or a combination of a motor and a speed reducer; when the spiral stirring paddle 4 rotates, it will drive the materials in the ice storage cavity 111 to be output to the ice outlet cavity 121, and the spiral stirring paddle 4 plays a role in stirring materials, which can disperse materials and avoid the materials being stored in a lump shape, so that the ice materials in the ice storage container 1 can be dispersed into granular shape, and different ice materials can be mixed uniformly (the ice storage container 1 can be used to store different materials); at the same time, under the rotation of the spiral stirring paddle 4, the materials can be horizontally pushed to the ice outlet cavity 121, so that the materials can be output from the ice outlet 122.

[0064] The spiral stirring paddle 4 can be optimized to include a stirring shaft 41, a stirring edge 42, and a backflow side plate 43.

[0065] The stirring edge 42 is connected to the stirring shaft 41 and spirally surrounds the stirring shaft 41 along the length direction of the stirring shaft 41, and the end of the stirring edge 42 is close to the ice outlet 122.

[0066] The backflow side plate 43 is arranged at the end of the stirring edge 42, and an L-shaped backflow groove 421 is formed between the end of the stirring edge 42 and the backflow side plate 43; the L-shaped backflow groove 421 rotates with the stirring edge 42, the stirring edge 42 receives materials near the ice outlet 122 in the area of the backflow side plate 43, and the stirring edge 42 discharges materials in the area other than the backflow side plate 43, so that the materials are away from the ice outlet 122.

[0067] The spiral stirring paddle 4 of the scheme can not only stir and convey the material, but also separate the material at the ice outlet 122 from the ice outlet 122 to avoid the material from blocking the ice outlet 122. Specifically, the stirring edge 42 is spirally distributed outside the stirring central shaft 41, and can be connected to the stirring central shaft 41 at the middle, at the end, or at other positions. The stirring edge 42 is spirally distributed, so that the two ends of the stirring edge 42 extend in a curved surface. The end of the stirring edge 42 is provided with a reflux side plate 43, and the two form an L-shaped reflux groove 421. When the stirring edge 42 rotates, the L-shaped reflux groove 421 rotates circularly. When the L-shaped reflux groove 421 rotates, the inner wall of the ice cavity 121 near the ice outlet 122 is scraped between the stirring edge 42 and the reflux side plate 43, so that the scraped material is received between the stirring edge 42 and the reflux side plate 43. The material rotates with the L-shaped reflux groove 421. Since the end of the stirring edge 42 is curved, the reflux side plate 43 blocks the material when it is at a low position, and the material is not easy to fall off in the area of the reflux side plate 43. When the reflux side plate 43 rotates to a high position, the lower part of the stirring edge 42 is hollowed out, the material is no longer supported by the reflux side plate 43, and the material falls off in the area without the reflux side plate 43, so that the material is separated from the ice outlet 122, the ice outlet 122 is not easy to retain the material, and the material is not easy to accumulate in the ice outlet 122, thereby reducing the influence of the accumulated material on the subsequent discharge, and preventing the material retained in the ice outlet 122 from freezing. The single driving source is used to drive the stirring central shaft 41 to rotate, so that the functions of stirring the material, conveying the material, and preventing the material from accumulating in the ice outlet 122 are realized at the same time.

[0068] The output end of the rotating motor 5 is connected to the spiral stirring paddle 4. The rotating motor 5 drives the spiral stirring paddle 4 to rotate clockwise or counterclockwise, so as to drive the material in the ice storage container 1 to be pushed to the ice outlet 122 in one rotating direction, and to drive the material to be separated from the ice outlet 122 in the other rotating direction through the L-shaped reflux groove 421.

[0069] The rotating motor 5 of the scheme is a known motor. The rotating direction of the rotating motor 5 can be adjusted to clockwise rotation or counterclockwise rotation. As shown in the figure, when the spiral stirring paddle 4 is designed to rotate counterclockwise, the stirring edge 42 pushes the material in the ice storage container 1 to the ice outlet 122. Therefore, only the spiral stirring paddle 4 designed to rotate counterclockwise is needed to push the material to discharge. When the ice storage container 1 is discharged, the rotating direction of the rotating motor 5 can be switched, and the spiral stirring paddle 4 is switched to clockwise rotation, so that the L-shaped reflux groove 421 is used to scrape the inner wall of the ice storage container 1 near the ice outlet 122, and the material remaining near the ice outlet 122 is refluxed to be far away from the ice outlet 122.

[0070] The stirring edge 42 of the L-shaped return flow groove 421 can extend from the vicinity of the ice outlet 122 to the opening of the ice storage cavity 111.

[0071] In the optimal embodiment, the stirring edge 42 extends from the vicinity of the ice outlet 122 to the ice storage cavity 111, i.e. the area of the non-return flow side plate 43 is where the material is output to the ice storage cavity 111 when the ice storage cavity 111 is rotated; in this way, the material does not fall off in the area of the return flow side plate 43, i.e. the material does not fall off within the ice outlet cavity 121, and the return flow side plate 43 extends to the ice storage cavity 111 (e.g. the opening of the ice cavity 111), and when the return flow side plate 43 is rotated to the ice storage cavity 111 and no longer supports the material, the material will fall off at the opening of the ice storage cavity 111, thereby achieving rapid return flow of the material from the ice outlet 122 to the ice storage cavity 111, and the ice outlet cavity 121 is not prone to material accumulation.

[0072] A cold beverage machine is provided with the ice outlet structure capable of preventing ice from falling out of the ice outlet according to any of the above embodiments.

[0073] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
