Description

Technical Field

[0001] The present invention relates to the technical field of cold drink machines, and in particular to cold drink equipment and a control method thereof. Background Art

[0002] Cold drink equipment can usually process liquid raw materials into ice-like products (such as smoothies, ice cream, etc.). It generally includes a refrigeration system and a material making system, wherein the refrigeration system includes a compressor, a condenser and an evaporator, and the material making system includes a motor rotating device and a rotating scraper. When in use, first pour the raw materials such as beverages and milk into the feed hood, and then the raw materials in the feed hood are frozen and heat exchanged through the evaporator set in or outside the material making barrel. As the freezing process proceeds, the raw materials gradually form a solid-liquid mixture. At the same time, the motor rotating device drives the rotating scraper to stir these solid-liquid mixtures in the feed hood to prevent the solid-liquid mixture from forming ice cubes, ensuring that the solid-liquid mixture can form products such as smoothies or ice cream.

[0003] However, some traditional cold drink equipment uses shaded pole motors to stir the solid-liquid mixture. Due to the low speed regulation accuracy and speed regulation response efficiency of shaded pole motors, the stirring effect will be greatly affected, making it unsuitable for scenarios with high speed regulation requirements and variable speed regulation. For example, the stirring speed cannot be dynamically adjusted according to the production requirements of different products (such as smoothies or ice cream), and only a single type of frozen dessert can be produced. At the same time, when a single motor stirring control logic is used to realize the production of smoothies or ice cream, the ice cream or smoothie often stirs unevenly and clumps. When clumps occur, the insufficiently stirred ice cream or smoothie becomes thinner due to the low air content, thereby affecting the hardness of the ice cream or smoothie, and then affecting the taste of the smoothie.

[0043] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] like Figures 1 to 3 As shown, a specific embodiment of the present invention provides a cold drink device, including a body 1, a refrigeration mechanism 2, a stirring mechanism 3, a feeding and discharging mechanism 4 and a main control device 5 arranged on the body 1, the feeding and discharging mechanism 4 includes a material making barrel 41, a discharging mechanism 42 arranged at one end of the material making barrel 41 and a temperature sensor 43 arranged in the material making barrel 41, the material making barrel 41 can accommodate raw materials for making cold drinks and a solid-liquid mixture after molding, the material making barrel 41 is provided with a feeding port 441, and the raw materials are poured through the feeding port 441; the discharging mechanism 42 is used to output the solid-liquid mixture after molding, such as smoothies or ice cream.

[0045] The refrigeration mechanism 2 is used to provide cooling for the material barrel 41 so that the material is in a low-temperature molding environment; the stirring mechanism 3 includes a variable speed motor device 31 and a stirring member 32, the variable speed motor device 31 is in transmission connection with the stirring member 32, the stirring member 32 is arranged in the material barrel 41, and the variable speed motor device 31 can drive the stirring member 32 to rotate in the material barrel 41 to stir the material. Among them, the use of the variable speed motor device 31 can achieve stepless speed regulation, a wide speed regulation range and good smoothness, which can effectively achieve speed regulation work under different functions or different states, such as smoothies and ice creams with different speed regulation requirements, and ice cream has a higher stirring rate requirement than smoothies.

[0046] The temperature sensor 43 is connected to the main control device 5, and is used to detect the temperature data in the material making barrel 41 and send it to the main control device 5; the main control device 5 is electrically connected to the refrigeration mechanism 2 and the variable speed motor device 31 respectively, and is used to control the refrigeration mechanism 2 to provide a refrigeration environment of a preset functional mode for the material making space of the material making barrel 41 according to the temperature data and the input material making function command, and control the variable speed motor device 31 to adjust the speed and rotation direction of the stirring blade 32 in a preset functional mode according to the material making function command, so as to perform material making work of different cold drink products. For example, when a smoothie or ice cream function command is input, the refrigeration mechanism 2 can be controlled to perform a refrigeration work of a corresponding functional temperature according to the detected temperature data, and the variable speed motor device 31 can be controlled to perform a stirring work of a stirring mode of a corresponding function, so that the raw materials can be fully and evenly cooled and fully mixed with the air, so as to improve the shape of ice cream or smoothie and ensure its molding hardness, thereby realizing the production of smoothie or ice cream, and then realizing the material making function of different cold drink products by adjusting different working temperatures and stirring modes, meeting the user's one machine multi-purpose needs.

[0047] Specifically, Figure 1 , Figure 3 and Figure 5 As shown, the refrigeration mechanism 2 includes a compressor 21, a condenser 22 and an evaporator 23. The evaporator 23 is arranged in the material making barrel 41. The temperature sensor is arranged on the evaporator. The stirring member 32 surrounds the periphery of the evaporator 23. The two ends of the compressor 21 are respectively connected to the inlet end of the condenser 22 and the outlet end of the evaporator 23 through pipelines, and the outlet end of the condenser 22 is connected to the inlet end of the evaporator 23. When the compressor 21 is in refrigeration operation, it can provide cooling for the evaporator 23, thereby providing cooling for the internal space and materials of the material making barrel 41 through the evaporator 23, and stirring the materials through the stirring member 32 sleeved on the evaporator 23, so as to ensure the stable operation of the low-temperature material making of smoothies or ice creams.

[0048] Furthermore, if Figure 1 , Figure 3 and Figure 5As shown, the upper part or the upper middle part of the cold drink equipment includes a stirring zone 6 and a driving zone 7 from front to back, the evaporator 23, the stirring member 32, and the material making barrel 41 are arranged in the stirring zone 6, and the variable speed motor device is arranged in the driving zone 7; the variable speed motor device 31 includes a mounting frame 311, a variable speed motor 312, a reducer 313, a coupling 314 and a stirring shaft 315, and the mounting frame 311 is installed on the end of the material making barrel 41 away from the discharging mechanism 42. The variable speed motor 312, the reducer 313 and the coupling 314 are connected in sequence and are all installed on the mounting frame 311. One end of the stirring shaft 315 is connected to the coupling 314, and the other end of the stirring shaft 315 passes through the evaporator 23 and is connected to the transmission connection part 321 of the stirring member 32. The variable speed motor 312 can drive the stirring member 32 to stir the material in the material preparation barrel 41, and can realize stepless stirring speed regulation, meeting the high speed regulation accuracy requirements and variable scenes. Among them, the variable speed motor 312 is tilted in the body 1 to reduce its occupied volume, thereby reducing the volume of the body 1.

[0049] The upper part or the upper middle part of the cold drink equipment also includes a driving heat dissipation zone 8. The driving zone 7 is arranged between the stirring zone 6 and the driving heat dissipation zone 8. The driving heat dissipation zone 8 includes a driving heat dissipation fan, which can extract the working heat in the driving zone out of the body to reduce the working temperature of the driving zone.

[0050] A refrigeration zone 9 is provided at the lower part of the cold drink equipment, in which a compressor 21, a condenser 22 and a cooling fan 91 are provided. The cooling fan 91 is arranged on one side of the condenser 22 and is used to extract the working heat in the refrigeration zone 9 out of the body to reduce the working temperature of the refrigeration zone.

[0051] The variable speed motor 312 is preferably a variable speed DC motor, but is not limited thereto.

[0052] Preferably, if Figure 2 As shown, the main control device 5 includes a main controller 51 and a control panel 52. The control panel 52 is connected to the main controller 51 and is used to send the function control instructions input by the user to the main controller 51 to achieve different functions. In other embodiments, the main control device 5 may also include a wireless communication terminal, and the main controller 51 can be connected to an external remote controller or a mobile terminal through the wireless communication terminal to achieve a wireless control function.

[0053] In order to facilitate the formed product to flow at the front end of the material making cylinder 41, as shown in FIG. Figure 1 and 3As shown, the material making barrel 41 includes a guide portion 411, and the guide portion 411 is arranged at one end of the material making barrel 41 close to the discharge mechanism 42, that is, the front end of the material making barrel 41; the guide portion 411 is gradually inclined from the upper part of the material making barrel 41 toward the direction of the discharge mechanism 42, and under the guiding effect of the inclined guide portion 411, the formed product can flow from the side of the discharge mechanism 42 to the upper part of the material making barrel 41 without affecting the product flowing from the middle part of the material making barrel 41 to the discharge mechanism 42, and under the continuous extrusion pressure, the smoothie located in the guide portion 411 can continuously flow back from the upper part of the material making barrel 41 to the middle part, thereby forming a circulation. Ice cream with smaller particles is easy to be trapped in smaller corners, but because the inner wall of the guide part 411 forms an inner concave surface, the connection between the inner concave surface and the material making barrel 41 is less likely to produce a hidden angle than the connection between a flat surface and the material making barrel 41, and is therefore more conducive to the smooth flow of ice cream with smaller ice crystal particles. Therefore, the cold drink equipment of the present invention can be applied to products such as smoothies and ice creams at the same time. By refluxing the smoothies and ice creams, the stirring efficiency and stirring effect can be improved.

[0054] Furthermore, if Figure 1 and Figure 4 A transition connection portion 412 is provided between the outer wall of the material making barrel 41 and the feed port 441 of the material making barrel 41. The transition connection portion 412 is used to form a transition connection between the feed port 441 and the material making barrel 41. The transition connection portion 412 gradually extends from the outer wall of the material making barrel 41 toward the feed port 441. After the raw material is frozen to form a solid-liquid mixture, the solid-liquid mixture can be accommodated in the transition connection portion 412 and gradually stirred and pushed from the transition connection portion 412, and the solid-liquid mixture can be pushed to the discharge port 418. The provision of the transition connection portion 412 not only increases the accommodation volume, but also facilitates the reflux of the solid-liquid mixture from the upper part of the material making barrel 41.

[0055] Specifically, the inner wall of the guide portion 411 is a concave continuous curved surface. The concave continuous curved surface allows the smoothie and ice cream to smoothly flow back toward the upper part of the material making barrel 41 at the position of the discharging mechanism 42, which is beneficial to the reflux of the solid-liquid mixture and forms a circulation of the solid-liquid mixture in the material making barrel 411.

[0056] In some embodiments, the transition connection part 412 is an arc transition or an inclined transition. The shape of the arc transition or the inclined transition can enable the solid-liquid mixture to smoothly move from the position of the feed port 441 to the middle of the material making barrel 411, and gradually move to the vicinity of the discharge port 418. Furthermore, the surface of the transition connection part 412 is a smooth curved surface, which can reduce the friction of the solid-liquid mixture in the transition connection part 412, thereby facilitating the movement of the solid-liquid mixture in the transition connection part 412, facilitating stirring and pushing the material, and reducing the occurrence of heaping and retention of the solid-liquid mixture in the transition connection part 412.

[0057] In some embodiments, the width of the transitional connection portion 412 gradually increases from the outer wall of the material-making barrel 41 toward the feed port 441, and the transitional connection portion 412 forms a gradually concentrated channel in the direction away from the feed port 441, so that the solid-liquid mixture moves to the middle of the material-making barrel 41. In other embodiments, the width of the transitional connection portion 412 gradually decreases from the outer wall of the material-making barrel 41 toward the feed port 441, so that the position of the transitional connection portion 412 can accommodate more solid-liquid mixture.

[0058] Preferably, the cross-sectional outer contour of the material preparation barrel 41 is a circle, an ellipse, or a quasi-ellipse formed by a smooth curve. The quasi-ellipse refers to a closed curve figure, a shape with a major axis and a minor axis but different from a standard ellipse in terms of edge curvature, symmetry, etc. Setting the cross-sectional outer contour can increase the material storage space of the material preparation barrel 41. At the same time, the closed contour formed by the smooth curve can reduce the friction of the solid-liquid mixture on the inner wall of the material preparation barrel 41, thereby reducing the occurrence of heaping, retention, etc., which is conducive to uniform stirring and improves the stirring effect.

[0059] like Figure 4 As shown, a side end surface 413 is provided at one end of the material making barrel 41 close to the discharging mechanism 42, and the discharging mechanism 42 is arranged on the side end surface 413. The squeezed solid-liquid mixture will be concentrated on the side end surface 413, and the upper part of the side end surface 413 is connected to the lower part of the guide part 411.

[0060] In this embodiment, the upper part of the side end surface 413 is tangentially connected to the lower part of the guide portion 411, and along the connection between the side end surface 413 and the guide portion 411, the solid-liquid mixture can be smoothly transferred from the side end surface 413 to the upper part of the material making barrel 41, wherein the phase connection point between the side end surface 413 and the guide portion 411 is the first phase connection point 414, and the solid-liquid mixture produces a first turn in the first phase connection point 414, so that the solid-liquid mixture can be transferred from the side end surface 413 to the upper part of the material making barrel 411.

[0061] The side wall of the material making barrel 41 is provided with a barrel surface 415, and the barrel surface 415 is the main side wall of the material making barrel 41, wherein the barrel surface 415 is connected to the upper part of the guide part 411. In the present embodiment, the barrel surface 415 is tangentially connected to the upper part of the guide part 411, and the solid-liquid mixture flows along the guide part 411 and moves smoothly from the upper part of the guide part 411 to the junction of the barrel surface 415, wherein the phase connection point between the barrel surface 415 and the guide part 411 is the second phase connection point 416, and the solid-liquid mixture makes a second turn in the second phase connection point 416, so that the solid-liquid mixture can flow back to the middle part of the material making barrel 411 to form a circulation.

[0062] In the embodiment of the present invention, the number of the second phase connecting wires 416 is two and they are symmetrically inclined and bent from the top of the material making barrel 41 to the two sides of the guide portion 411. The two second phase connecting wires 416151 are provided to guide the movement of the solid-liquid mixture from the symmetrical two sides of the guide portion 411, and the inclined and bent arrangement can reduce the space for the solid-liquid mixture with smaller ice crystal particles such as ice cream to be retained in the guide portion 411, thereby improving the smoothness of the reflux of the solid-liquid mixture.

[0063] Furthermore, one end of the two second phase connections 416 intersects with each other, and the other ends bend and extend toward both sides of the guide portion 411 and are respectively connected to the two ends of the first phase connection 414. Along the reflux direction of the solid-liquid mixture, the two second phase connections 416 converge and intersect from the two ends of the first phase connection 414 toward the upper part of the material making barrel 41, so that when the solid-liquid mixture moves in the guide portion 411, it can be concentrated to the center of the upper part of the material making barrel 41 to form a more concentrated reflux route, so that the overall cross-section of the refluxed solid-liquid mixture is smaller, and under the condition of a constant flow rate, the reflux flow rate of the solid-liquid mixture is improved, the reflux speed can be accelerated, and the solid-liquid mixture in a stirred state can be smoothly moved to the side end surface 413, ensuring the reflux efficiency and stirring effect.

[0064] like Figure 1 , Figure 3 and Figure 4 As shown, the material making barrel 41 also includes a feeding portion 44, and the feeding portion 44 is arranged on the transition connecting portion 412, and a feeding port 441 is arranged on the feeding portion 44, and the transition connecting portion 412 protrudes upward from the barrel body surface 415 of the material making barrel 41 and is arranged at one end of the material making barrel 41 away from the discharging mechanism 42 to expand the space for accommodating raw materials, facilitate the entry of more raw materials, and enable the raw materials after entering to be fully frozen and stirred.

[0065] A feed cavity 417 is provided in the transition connection portion 412, and the feed cavity 417 is connected to the storage space of the material making barrel 41. When the raw materials are poured in, the raw materials first enter the feed cavity 417 and then enter the storage space. The diameter of the longitudinal section of the feed cavity 417 is larger than the maximum diameter of the longitudinal section of the storage space, so that the volume of the raw materials and solid-liquid mixture that the material making barrel 411 can accommodate is increased.

[0066] Furthermore, the discharging mechanism 42 includes a discharging hopper 421, a handle 422 and a discharging valve 423. The discharging hopper 421 is arranged on the side end surface 413. The side end surface 413 is provided with a discharging port 418. The discharging port 418 can be communicated with the discharging hopper 421. One side of one end of the handle 422 is hinged to the discharging hopper 421, and the other side of one end of the handle 422 is hinged to the discharging valve 423. The handle 422 can swing relative to the discharging hopper 421. During the swinging process of the handle 422, the handle 422 can drive the discharging valve 423 to rise or fall to open or close the discharging hopper 421, thereby achieving the effect of discharging or closing the discharging hopper 421.

[0067] Accordingly, if Figure 6 As shown, the present invention also provides a control method for cold drink equipment, which is applied to the above-mentioned cold drink equipment, comprising:

[0068] S101, real-time acquisition of current temperature data and current material preparation function commands in the material preparation barrel;

[0069] It should be noted that the temperature sensor set on the material making barrel can detect the current temperature data in the material making barrel in real time; when the user inputs the material making control signal, the corresponding current material making function command can be obtained, wherein the current material making function command is any one of the material making function commands of different cold drink products, such as at least including ice cream function command or smoothie function command, but not limited to this. Among them, the ice cream function command includes smoothie making commands of different raw materials, such as ice cream of coffee raw materials, cola raw materials, milk raw materials or mixed raw materials; the smoothie function command includes smoothie making commands of different raw materials, such as ice cream making commands of coffee raw materials, cola raw materials, milk raw materials or mixed raw materials; the smoothie making commands of different raw materials and the ice cream making commands of different raw materials are equipped with the hardness gear control library of the corresponding material making function and the functional hardness gear control rule group of different hardness gears in the preset functional hardness gear control library; the material making commands of different raw materials of the same function (such as smoothie or ice cream function) execute different control mode parameters when executing the following corresponding material making work.

[0070] S102, pairing the current material preparation function command with a preset functional hardness gear control library to obtain a functional hardness gear control rule group of a corresponding material preparation function, wherein the functional hardness gear control rule group includes a functional material preparation command of a corresponding hardness gear, a preset morphology trigger rule, and a preset molding trigger rule;

[0071] Specifically, the current material preparation function command includes the current function command and the current hardness level command, that is, the ice cream function command or the smoothie function command includes the corresponding current function command and the current hardness level command. Any ice cream function or smoothie function corresponds to material preparation commands with different hardness levels, that is, different hardness level commands.

[0072] The step of pairing the current material making function command with the preset function hardness gear control library to obtain the function hardness gear control rule group of the corresponding material making function comprises:

[0073] Step 1: Pairing the current function command with a preset function hardness level control library to obtain a hardness level control library for a corresponding material making function;

[0074] Step 2: Pairing the current hardness gear command with the hardness gear control library to obtain a corresponding functional hardness gear control rule group.

[0075] It should be noted that the functional hardness gear control library includes hardness gear control libraries for different functions. When the current function command is successfully paired with the preset functional hardness gear control library, the hardness gear control library corresponding to the smoothie or ice cream function can be obtained. When the current hardness gear command required by the user is successfully paired with the preset functional hardness gear control library, the functional hardness gear control rule group of the hardness gear corresponding to the smoothie or ice cream function can be obtained, thereby realizing the corresponding hardness production of smoothies or ice cream.

[0076] S103, starting the refrigeration mechanism to work, and controlling the variable speed motor to perform stirring work at the corresponding hardness level according to the functional material preparation command;

[0077] Specifically, the step of controlling the variable speed motor to perform stirring work at a corresponding hardness level according to the functional material preparation command includes:

[0078] Step 1: When the functional material making command is an ice cream material making command, the variable speed motor is controlled to perform stirring at a first preset speed and in a single stirring direction;

[0079] Step 2: When the functional material preparation command is a smoothie preparation command, the variable speed motor is controlled to perform a stirring operation at a second preset speed and in a single stirring direction.

[0080] It should be noted that when the functional material preparation command is an ice cream material preparation command, ice cream is made; when starting to prepare the material, the compressor is first turned on for rapid pre-cooling, and the motor is controlled to stir the material at a first preset speed and in a single stirring direction; in the stirring state, the material will be fully and evenly cooled, thereby effectively preventing local agglomeration or granularity, and effectively improving the subsequent ice cream forming effect of the material.

[0081] Preferably, the first preset rotation speed is preferably 130±5 rpm, but is not limited thereto and can be adjusted according to actual conditions.

[0082] Preferably, the single stirring direction is a positive rotation direction, that is, a clockwise rotation direction, but it is not limited thereto and can be adjusted according to actual conditions.

[0083] Correspondingly, when the functional material preparation command is a smoothie preparation command, smoothie making is performed. At this time, the smoothie making operation is similar to the above-mentioned ice cream making operation. The difference is that when making smoothies, the motor is controlled to stir the materials at a different second preset speed to achieve the stirring effect required for the smoothie.

[0084] Preferably, the second preset rotation speed is preferably 80±5 rpm, but is not limited thereto and can be adjusted according to actual conditions.

[0085] S104, when the current temperature data meets the preset shape triggering rule, controlling the variable speed motor to perform shape adjustment work of the corresponding hardness gear;

[0086] Specifically, when the current temperature data meets the preset shape triggering rule, the step of controlling the variable speed motor to perform shape adjustment work of the corresponding hardness gear includes:

[0087] Step 1: when the preset shape trigger rule is an ice cream preset shape trigger rule, determine whether the current temperature data is within a first preset temperature threshold range; if it is determined to be yes, it means that the ice cream preset shape trigger rule is satisfied, and control the motor to perform stirring at a third preset speed, and alternately switch the forward and reverse stirring directions at a first preset interval time;

[0088] Step 2: When the preset shape trigger rule is the smoothie preset shape trigger rule, determine whether the current temperature data is within the second preset temperature threshold range. If it is determined to be yes, it means that the smoothie preset shape trigger rule is met, and the motor is controlled to perform stirring at a fourth preset speed, and the forward and reverse stirring directions are alternately switched at a second preset interval.

[0089] It should be noted that when the preset shape trigger rule is the ice cream preset shape trigger rule and the current temperature data is within the first preset temperature threshold range, it means that the ice cream preset shape trigger rule is met, and the material begins to enter the ice cream shape adjustment stage, and the shape and expansion rate of the ice cream during molding need to be adjusted in time to avoid reducing the taste; if the single stirring logic is still maintained at this time, the ice cream will be unevenly stirred and the ice cream will agglomerate. When agglomeration occurs, the insufficiently stirred ice cream will directly reduce the shape and expansion rate of the ice cream during molding due to the low content of air mixed in, making the taste worse. In this regard, the present invention controls the motor to stir the material at a third preset speed, and alternately switches the forward and reverse stirring directions at a first preset interval time, that is, alternately switches to clockwise or counterclockwise rotation directions. At this time, the stirring paddle will push the material forward and backward at the first preset interval time, so that the material still maintains uniform cooling and sufficient air mixing, so as to improve the expansion rate and shape of the ice cream, thereby improving the taste; at the same time, the second preset speed is lower than the first preset speed. Reducing the stirring speed at this stage can alleviate the thinning problem caused by stirring and further improve the shape of the ice cream during molding. Otherwise, it means that the requirements are not met, and the material preparation and waiting process will continue.

[0090] Preferably, the first preset temperature threshold range is preferably 0±0.3 degrees, but is not limited thereto and can be adjusted according to actual conditions.

[0091] Preferably, the third preset rotation speed is preferably 80±5 rpm, but is not limited thereto and can be adjusted according to actual conditions.

[0092] Preferably, the first preset interval time is preferably 60 seconds, but it is not limited thereto and can be adjusted according to actual conditions. In the above stage of the present embodiment, the speed of the motor is reduced to 80 RPM, and the material is stirred alternately at intervals of 60 seconds in the forward direction and 60 seconds in the reverse direction, which can increase the expansion rate of the ice cream and the shape during molding, thereby improving the taste of the ice cream.

[0093] Correspondingly, when the preset shape trigger rule is a smoothie preset shape trigger rule and the current temperature data is within the second preset temperature threshold range, it means that the smoothie preset shape trigger rule is met, and the material begins to enter the smoothie shape adjustment stage and performs similar operations to the above-mentioned ice cream to adjust the shape of the smoothie during forming and increase the hardness. The difference is that when making the smoothie, the motor is controlled to stir at a fourth preset speed and alternately switches the forward and reverse stirring directions at a second preset interval.

[0094] Preferably, the second preset temperature threshold range is preferably 0±0.1 degrees, but is not limited thereto and can be adjusted according to actual conditions.

[0095] Preferably, the fourth preset rotation speed is preferably 40±5 rpm, but is not limited thereto and can be adjusted according to actual conditions.

[0096] Preferably, the second preset interval time is preferably 40 seconds, but it is not limited thereto and can be adjusted according to actual conditions. In the above stage of the present embodiment, the speed of the motor is reduced to 40 RPM, and the material is continuously and alternately stirred at intervals of 40 seconds in the forward direction and 40 seconds in the reverse direction, which can improve the shape and hardness of the smoothie, thereby improving the taste of the smoothie.

[0097] S105. When the current temperature data meets the preset molding trigger rule, the variable speed motor and the refrigeration mechanism are controlled to perform hardness maintenance work at the corresponding hardness level.

[0098] Specifically, when the current temperature data meets the preset molding trigger rule, the step of controlling the variable speed motor and the refrigeration mechanism to perform the hardness maintenance work at the corresponding hardness level includes:

[0099] Step 1: when the preset molding trigger rule is an ice cream preset molding trigger rule, determining whether the current temperature data is within a third preset temperature threshold range; if the determination is yes, it means that the ice cream preset molding trigger rule is satisfied, and the ice cream hardness maintenance work is performed;

[0100] Step 2: When the preset shaping trigger rule is a smoothie shaping trigger rule, determine whether the current temperature data is within a fourth preset temperature threshold range. If it is determined to be yes, it means that the smoothie shaping trigger rule is met, and the smoothie hardness maintenance work is performed.

[0101] It should be noted that when the preset ice cream molding trigger rules or the preset smoothie molding trigger rules are met, the ice cream or smoothie molding maintenance work is entered to ensure that the overall hardness of the ice cream or smoothie meets the required production requirements, thereby improving the taste.

[0102] like Figure 7 As shown, the steps of maintaining the hardness of the ice cream include:

[0103] S201, controlling the refrigeration mechanism and the variable speed motor to stop working, and calculating the stop time;

[0104] It should be noted that when the ice cream is formed, the compressor and the motor are controlled to stop working and enter the heat preservation state to maintain the shape and taste of the ice cream, and the stop time is calculated.

[0105] S202, when the stop time reaches a first preset time threshold, controlling the variable speed motor to perform stirring at a fifth preset speed and in a single stirring direction;

[0106] It should be noted that, in the heat preservation state, in order to make the ice cream still maintain a good taste and shape, that is, the ice cream is not too hard or too soft, the present invention controls the motor to stir the ice cream at a low speed at a fifth preset speed and in a single stirring direction to maintain the good taste and shape of the ice cream.

[0107] Preferably, the fifth preset rotation speed is preferably 80±5 rpm, but is not limited thereto and can be adjusted according to actual conditions.

[0108] Preferably, the single stirring direction is a positive rotation direction, that is, a clockwise rotation direction, but it is not limited thereto and can be adjusted according to actual conditions.

[0109] S203, determining whether the current temperature data is less than a first preset temperature adjustment threshold value, if the determination is yes, initializing the stop time, and returning to step S201, if the determination is no, controlling the refrigeration mechanism to work, and controlling the variable speed motor to perform stirring at a sixth preset speed, and alternately switching the forward and reverse stirring directions at a third preset interval time;

[0110] It should be noted that the ice cream temperature is continuously monitored. If the current temperature data is less than the first preset temperature adjustment threshold, it means that the temperature is too low, which will cause the ice cream to harden and affect the taste. At this time, the process should return to step S201 to continue to stop the refrigeration and stirring work to gradually increase the ice cream temperature. If the current temperature data is greater than or equal to the first preset temperature adjustment threshold, it means that the temperature is too high, which will cause the ice cream to soften. At this time, the compressor is controlled to continue the refrigeration work, and the motor is controlled to stir the ice cream at the sixth preset speed, and the forward and reverse stirring directions are alternately switched at the third preset interval. At this time, the stirring paddle will push the ice cream forward and backward at the third preset interval, so that the ice cream as a whole maintains a uniform cooling effect and maintains the optimal shape, thereby ensuring that the overall hardness of the ice cream meets production and customer needs.

[0111] Preferably, the first preset temperature adjustment threshold is preferably -4±0.2°, but is not limited thereto and can be adjusted according to actual conditions.

[0112] Preferably, the sixth preset rotation speed is preferably 80±5 rpm, but is not limited thereto and can be adjusted according to actual conditions.

[0113] Preferably, the third preset interval time is preferably 60s, but is not limited thereto and can be adjusted according to actual conditions.

[0114] S204, determine whether the current temperature data is less than the second preset temperature adjustment threshold. If it is, initialize the stop time and return to step S1. If it is not, continue to control the refrigeration mechanism to work, and control the variable speed motor to stir at the seventh preset speed, and alternately switch the forward and reverse stirring directions at the fourth preset interval time, and then return to step S204.

[0115] It should be noted that the ice cream temperature is continuously monitored. If the current temperature data is less than the second preset temperature adjustment threshold, it means that the temperature is too low, which will cause the final ice cream to harden and affect the taste. At this time, the process should return to step S201 to continue to stop the refrigeration and stirring work, and re-perform the hardness maintenance work. If the current temperature data is greater than or equal to the second preset temperature adjustment threshold, it means that the temperature is high, which will cause the final ice cream to soften. At this time, the compressor is controlled to continue the refrigeration work, and the motor is controlled to stir the ice cream at the seventh preset speed, and the forward and reverse stirring directions are alternately switched at the fourth preset interval. At this time, the stirring paddle will push the ice cream forward and backward at the fourth preset interval, so that the ice cream as a whole maintains a uniform cooling effect and continues to maintain the optimal shape, thereby ensuring that the overall hardness of the ice cream meets the production and customer requirements, and thus meets the taste requirements.

[0116] Preferably, the second preset temperature adjustment threshold is preferably -2±0.2°, but is not limited thereto and can be adjusted according to actual conditions.

[0117] Preferably, the seventh preset rotation speed is preferably 80±5 rpm, but is not limited thereto and can be adjusted according to actual conditions.

[0118] Preferably, the fourth preset interval time is preferably 60s, but is not limited thereto and can be adjusted according to actual conditions.

[0119] like Figure 8 As shown, the steps of maintaining the hardness of the smoothie include:

[0120] S301, performing heat preservation maintenance work according to the third preset temperature adjustment threshold, and performing heat preservation state timing;

[0121] It should be noted that when the current temperature data in the ice-making chamber reaches the third preset temperature adjustment threshold of the current gear, the heat preservation state is entered, and the heat preservation maintenance work is performed according to the third preset temperature adjustment threshold of the current gear, so as to maintain the heat preservation of the smoothie in the ice-making chamber at the preset temperature threshold, and the heat preservation state timing is performed.

[0122] S302, when the heat preservation state timing time is greater than the second preset time threshold, updating the third preset temperature adjustment threshold and performing heat preservation maintenance work;

[0123] It should be noted that when the insulation state timing time is greater than the second preset time threshold, the temperature adjustment mode is activated. As the air inside the smoothie gradually becomes thinner, the different insulation stages of the smoothie can be adjusted to prevent the smoothie from becoming thinner or the hardness of the smoothie from decreasing. The required hardness of the smoothie can be effectively maintained, thereby meeting the user's requirements for smoothie hardness and improving the user's taste.

[0124] The step of updating the third preset temperature adjustment threshold comprises: updating the third preset temperature adjustment threshold of the current gear according to the temperature update rule of the current gear, and updating the second preset time threshold according to the time update rule of the current gear.

[0125] Further, the temperature update rule of the current gear includes: according to the temperature update calculation formula T=T-T1, updating the new third preset temperature adjustment threshold of the current gear, wherein T is the third preset temperature adjustment threshold of the current gear, and T1 is the temperature adjustment threshold of the current gear; the time update rule of the current gear includes: according to the time update calculation formula t=t+t1, updating the new second preset time threshold, wherein t is the second preset time threshold of the current gear, and t1 is the time adjustment threshold of the current gear.

[0126] It should be noted that each time the temperature adjustment work is performed, the third preset temperature adjustment threshold of the new current gear is calculated according to the above-mentioned temperature update calculation formula, and the second preset time threshold of the new current gear is calculated according to the above-mentioned time update calculation formula; then a new heat preservation maintenance work is performed according to the third preset temperature adjustment threshold, and when the new heat preservation maintenance work reaches the new second preset time threshold, the next step of temperature adjustment work is performed, thereby realizing the maintenance work of different heat preservation stages for the smoothie.

[0127] S303, determining whether the third preset temperature adjustment threshold is less than or equal to the preset gear heat preservation maintenance threshold; if so, performing heat preservation maintenance work according to the gear heat preservation maintenance threshold to maintain the current smoothie hardness; if not, returning to step S302.

[0128] It should be noted that when the third preset temperature adjustment threshold of the current gear reaches the preset gear insulation maintenance threshold of the current gear, it means that the third preset temperature adjustment threshold has reached the maintenance temperature required for the current smoothie hardness. The insulation work is carried out at this maintenance temperature, and the hardness of the produced smoothie can be maintained at the required hardness requirement, and its hardness change will not be easily affected by other factors, which can effectively meet the actual hardness and taste requirements of users. Otherwise, it means that the third preset temperature adjustment threshold of the current gear has not reached the preset gear insulation maintenance threshold of the current gear. At this time, the temperature adjustment work continues until the third preset temperature adjustment threshold is adjusted down to the gear insulation maintenance threshold. For example, if the initial third preset temperature adjustment threshold T of the current gear is 2°, the temperature adjustment threshold T1 is 0.4°, the initial preset time threshold t is 20min, the time adjustment threshold t1 is 10min and the gear insulation maintenance threshold is -2°, after 10 temperature adjustment operations, the current preset temperature threshold light will be equal to the gear insulation maintenance threshold. At this time, the final insulation work stage has been reached, and it can stably produce smoothies of the required hardness.

[0129] Among them, the time adjustment threshold can be adjusted according to actual conditions, and there is no need to increase the working time after each temperature adjustment work. For example, when the preset time threshold reaches 40, 50 or 60 minutes, the subsequent preset time threshold remains unchanged or decreases accordingly to a certain degree of time threshold, without too many restrictions.

[0130] Furthermore, if Fig. 9 As shown, the steps of the heat preservation and maintenance work include:

[0131] S401, when the current temperature data is less than or equal to the temperature threshold, stopping the refrigeration mechanism;

[0132] It should be noted that in the insulation state, when the detected current temperature data of the smoothie is less than or equal to the temperature threshold, it means that in the current insulation stage, the temperature of the smoothie is already low. At this time, the refrigeration work is stopped, that is, the compressor is stopped to prevent the material temperature from being too low, causing excessive freezing and wasting energy.

[0133] S402, when the current temperature data is greater than the temperature threshold and the refrigeration stop time is greater than the third preset time threshold of the current gear, starting the refrigeration mechanism;

[0134] It should be noted that when the refrigeration is stopped, when the detected current temperature data is greater than the temperature threshold and the refrigeration stop time is greater than the third preset time threshold of the current gear, the refrigeration is turned on, that is, the compressor is turned on to effectively maintain the hardness of the smoothie.

[0135] The temperature threshold is a preset temperature threshold of the current gear or a gear heat preservation and maintenance threshold, so as to perform heat preservation and maintenance work at different temperature thresholds.

[0136] S403, when the current temperature data is less than or equal to the temperature threshold and the refrigeration on time is greater than the fourth preset time threshold of the current gear, stop the refrigeration work and return to step S402;

[0137] It should be noted that when the current temperature data is less than or equal to the temperature threshold and the refrigeration turn-on time is greater than the fourth preset time threshold of the current gear, it means that the current temperature of the smoothie has met the insulation maintenance requirements. At this time, the refrigeration work is stopped and the above-mentioned insulation maintenance work is cyclically performed in this insulation stage to ensure that the hardness of the smoothie in the current gear meets production and customer needs.

[0138] Preferably, the second preset time threshold, the third preset time threshold and the fourth preset time threshold can be set and adjusted accordingly according to actual needs.

[0139] Preferably, in order to more accurately determine whether the hardness of the smoothie meets the requirement, the step of maintaining the hardness of the smoothie also includes:

[0140] Step 1: Under the insulation state, obtain the current speed of the motor in real time;

[0141] Step 2: When the current speed of the motor is greater than or equal to an eighth preset speed, the refrigeration operation is stopped;

[0142] Step 3: When the current speed of the motor is greater than or equal to the ninth preset speed and the temperature start condition is triggered, the cooling operation is started;

[0143] It should be noted that when the temperature start-up condition is that the current temperature data is greater than the temperature threshold and the refrigeration stop time is greater than the fifth preset time threshold of the current gear, the temperature threshold is the preset temperature threshold of the current gear or the gear insulation maintenance threshold.

[0144] When in the warm-keeping state, the current motor speed of the variable speed motor is also obtained in real time. When the current motor speed is greater than or equal to the eighth preset speed, it means that the current hardness of the smoothie has met the requirements, and the refrigeration work is stopped to avoid excessive hardness of the smoothie and save energy; when the current motor speed is greater than or equal to the ninth preset speed and the temperature start condition is triggered, the refrigeration work is turned on to maintain the hardness of the smoothie. Among them, the ninth preset speed is the start speed, which is greater than the eighth preset speed.

[0145] Preferably, the smoothie making commands for different raw materials or the smoothie making commands for different raw materials have different discharging stirring speeds, so that when discharging, fast discharging work can be performed for different raw material production scenarios, which can prevent material piling and improve discharging efficiency.

[0146] In summary, the present invention can control the refrigeration mechanism to provide a refrigeration environment of a preset functional mode for the material preparation space of the material preparation barrel according to the temperature data and the input material preparation function command, and control the variable speed motor device to adjust the speed and rotation direction of the stirring blade in a preset functional mode according to the material preparation function command, so as to perform material preparation work for different cold drink products, thereby meeting the user's demand for one machine with multiple uses;

[0147] At the same time, different motor stirring control logics are used under different working conditions to avoid local agglomeration or large particles of materials during production, so as to maintain the overall shape and hardness of the materials, thereby improving the taste of the output materials and meeting the actual needs of users.

[0148] Secondly, during the stirring process, the solid-liquid mixture will move to the front end of the material making barrel. In order to enable the solid-liquid mixture at the front end of the material making barrel to flow back smoothly, the material making barrel also includes a guide portion, which is gradually inclined from the upper part of the material making barrel toward the direction of the discharging mechanism, so that the guide portion can guide the solid-liquid mixture to move upward to the upper part of the material making barrel, and move obliquely to the middle part of the material making barrel, thereby completing the reflux of the smoothie. Since the inner wall of the guide portion forms an inner concave surface, the inner concave surface is not easy to form a corner for hiding, so products such as ice cream with smaller particles are not easy to be retained in the guide portion, which facilitates the reflux of the small-particle solid-liquid mixture, thereby being suitable for the reflux work of smoothies and ice creams, and improving the stirring efficiency and stirring effect.

[0149] Finally, it should be noted that the above-described embodiments are only specific implementations of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the above-mentioned embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-mentioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and should be covered within the protection scope of the present invention.
