Description

A barrel-type evaporator structure, a smoothie maker, and a method for controlling the texture of smoothies.

[0001] Any and all applications incorporated herein by reference and forming part of this disclosure, with respect to any foreign or domestic priority claims of such applications, are identified in the application data page as filed with this application. Technical Field

[0002] This application relates to the field of smoothie maker technology, specifically to a barrel evaporator structure, a smoothie maker, and a method for controlling the texture of smoothies. Background Technology

[0003] The evaporator is an important component in refrigeration equipment. It is a type of heat exchanger. Most refrigeration equipment (such as snow melting machines) generally include an evaporator body and a coil. The evaporator body includes inner and outer shells. The coil is sleeved on the inner shell and contacts the outer shell wall. For example, Chinese Patent No. CN202420084306.9 discloses a barrel-type evaporator structure and a snow melting machine, which includes an evaporation barrel that is closed at one end and open at the other end. An evaporation tube body is arranged inside the evaporation barrel. The evaporation tube section of the evaporation tube body is arranged in an S-shape along the axial direction of the evaporation barrel and forms a cylindrical structure. The refrigerant inlet section and refrigerant outlet section at the beginning and end of the evaporation tube body extend out of the outer side of the evaporation barrel through the open port. However, in the above-described structure, the outer wall of the evaporator tube is in contact with and conducts heat to the inner wall of the evaporator cylinder, forming two walls that separate them. This results in a larger heat transfer medium and lower heat transfer efficiency. Furthermore, the evaporator tube needs to be wound in an S-shape and placed inside the evaporator cylinder, which increases manufacturing costs. Additionally, a close fit between the evaporator tube and the evaporator cylinder is required; otherwise, heat transfer will be affected. The manufacturing process demands high precision and is structurally complex. Therefore, further improvements are necessary.

[0004] Meanwhile, to meet the different taste preferences of users for chilled products, it is necessary to adjust and control the firmness of the chilled product. Existing control methods use temperature detection, i.e., a temperature sensor detects the cooling temperature of the beverage product. When the beverage product's temperature drops to a predetermined value, the machine automatically stops. While this can achieve adjustment and control of the firmness of the chilled product, different beverage products have significant differences in firmness at the same temperature. Furthermore, ice particles are formed when the beverage product reaches its freezing point, and some of these ice particles come into contact with the temperature sensor, affecting the sensor's detection results and causing misjudgments. Another control method uses current detection, i.e., detecting the current of the stirring motor in the mixing device. When the beverage product freezes, the resistance of the stirring motor increases, and the current increases accordingly. When the current reaches a preset value, the machine automatically stops. This control method can solve the problem of different beverage products having different freezing points. However, the operating current of the stirring motor is greatly affected by ambient temperature. In addition, when users add granules or other solids to the beverage product, it can easily affect the resistance of the stirring motor in a short time, causing misjudgments. Therefore, further improvements are necessary. Technical issues

[0031] Furthermore, the set working time and default working time of the cooling device both start counting down from when the real-time cooling temperature of the beverage product detected by the temperature sensor reaches the target cooling temperature value, and end when the countdown is complete.

[0032] Furthermore, the target cooling temperature is 5 degrees to -10 degrees, and it is stored in memory.

[0033] Furthermore, the memory stores various types of beverage products, each corresponding to a different default operating time of the cooling device and a unified target cooling temperature value.

[0034] Furthermore, the temperature sensor is mounted on the barrel evaporator structure and is located near the discharge port of the barrel.

[0041] Compared with the prior art, the beneficial effects of this application are:

[0042] Technical solution of Implementation Example 1:

[0043] This invention, through structural improvements, provides spiral grooves on the outer wall of the inner barrel extending through both ends. The inner barrel is then fixed to the outer barrel by welding, with the spiral grooves forming a flow channel between them. This allows the condensed liquid to directly contact the inner wall of the outer barrel and conduct heat as it flows through the channel, thereby reducing the amount of heat transfer medium and improving heat transfer efficiency. Furthermore, the spiral grooves can be directly machined onto the outer wall of the inner barrel using rotary die casting. The inlet pipe and capillary tube can be connected to the first and second connecting parts at both ends of the spiral grooves, respectively. The manufacturing process is simple and the production cost is low. In addition, the outer wall of the inner barrel and the inner wall of the outer barrel do not require a high degree of fit, further reducing the manufacturing process and costs.

[0044] Technical solution of Example 2:

[0045] By utilizing the fit between the material bucket fastening part and the positioning fastening part, the material bucket can be disassembled and installed on the main body, improving the ease of disassembly and assembly. This facilitates daily cleaning and maintenance of the material bucket and evaporator by the user. After the material bucket is assembled, it can be axially sealed against the sealing axial lip through the material bucket axial support part, so that the material bucket can be sealed and assembled on the main body. Since the material bucket axial support part and the sealing axial lip are axially sealed, there are no high precision requirements for the shape and size of the circular assembly opening. This effectively avoids the disadvantages of the circular assembly opening being deformed or having dimensional errors, which would prevent it from forming a radial seal with the sealing element. This not only reduces the production process but also improves the sealing stability between the material bucket and the main body, ensuring that the ice sand inside the material bucket will not leak out.

[0046] Technical solution of Example 3:

[0047] The system stores different types of beverage products in its memory, along with the appropriate default operating time for each type of beverage. A control panel allows users to manually select the beverage type and adjust the default operating time of the cooling device. Temperature sensors monitor the beverage's temperature during stirring and cooling, enabling the main control board to stop the cooling device once the target cooling temperature is reached. This is achieved by controlling the cooling device to stop operating based on its default or set operating time, greatly satisfying the personalized adjustment needs for the texture of smoothies for different types of beverages. The precise real-time cooling temperature detection and control of the default or set operating time allow for accurate control of the smoothie's texture, while manual selection significantly enhances the flexibility of texture adjustment.

[0048] In actual use, the fast-rotating mixer can speed up the mixing of ice cream, which not only reduces cooling blockage but also improves the uniformity and texture of the ice cream. The slow-rotating mixer can slow down the dispensing speed of the ice cream, ensuring a stable dispensing speed and reducing the problem of ice cream falling off due to excessive dispensing speed, thus greatly improving the user experience.

[0073] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it. Example

[0074] Referring to Figures 1-4, the structure of this novel barrel-type evaporator includes an outer barrel 110 and an inner barrel 120. The inner barrel 120 is through at both ends and has a spiral groove 130 on its outer wall. The outer barrel 110 is closed at one end and open at the other end, with an end cap 111 fixed thereon. The inner barrel 120 is fixed inside the outer barrel 110 and forms a flow channel for condensate to flow through the spiral groove 130 and the inner wall of the inner barrel 120. The spiral groove 130 has a first connecting part 140 and a second connecting part 150 at both ends. The first connecting part 140 is connected to the liquid inlet pipe 160, and the second connecting part 150 is connected to the capillary tube 170. The outer ends of the liquid inlet pipe 160 and the capillary tube 170 extend toward the open end of the outer barrel 110, respectively.

[0075] In this embodiment, the inner barrel 120 can be connected by welding.

[0076] The inner barrel 120 can also be connected by Teflon welding or edge-curling and sealing, or by edge-curling and sealing.

[0077] In this embodiment, a spiral groove 130 is provided on the outer wall of the inner barrel 120 that extends through both ends, and the inner barrel 120 is fixed to the outer barrel 110 by welding. The spiral groove 130 forms a flow channel between the two, allowing the condensed liquid to directly contact the inner wall of the outer barrel 110 and conduct heat when flowing in the flow channel, thereby reducing the amount of heat transfer medium and improving heat transfer efficiency. Moreover, the spiral groove 130 can be directly processed on the outer wall of the inner barrel 120 by rotary die casting. The liquid inlet pipe 160 and the capillary tube 170 can be connected to the first connecting part 140 and the second connecting part 150 at both ends of the spiral groove 130, respectively. The manufacturing process is simple and the manufacturing cost is low. In addition, the outer wall of the inner barrel 120 and the inner wall of the outer barrel 110 do not require a high degree of fit, which can further reduce the manufacturing process and manufacturing cost.

[0078] As shown in Figure 4, the first connecting part 140 and the second connecting part 150 are respectively arranged in a planar shape and are respectively provided with connecting holes. The inner ends of the liquid inlet pipe 160 and the capillary tube 170 are welded and fixed to the first connecting part 140 and the second connecting part 150, respectively. The liquid inlet pipe 160 and the capillary tube 170 are respectively connected to the refrigerant channel through the connecting holes.

[0079] In this embodiment, the first connecting part 140 and the second connecting part 150 are planar, and their end faces are parallel to the end line of the inner barrel 120. The planar first connecting part 140 and the second connecting part 150 facilitate the connection of the liquid inlet pipe 160 and the capillary tube 170.

[0080] The inlet pipe 160 is welded and fixed to the first connecting part 140 and is connected to the inlet end of the refrigerant channel through the connecting hole. The capillary tube 170 is welded and fixed to the second connecting part 150 and is connected to the outlet end of the refrigerant channel through the connecting hole.

[0081] The inlet pipe 160 and the capillary tube 170 are respectively provided with a bending part, and are bent through the bending part and extend towards the open end of the outer barrel 110.

[0082] In this embodiment, the inlet pipe 160 is provided with a bend, and through the bend, it faces the first connecting part 140 and the open end of the outer barrel 110 respectively. The capillary tube 170 is provided with two bends, and through one bend, the capillary tube 170 faces the second connecting part 150 and the interior of the inner barrel 120, and through the other bend, it faces the open end of the outer barrel 110.

[0083] A gap is formed between the inlet tube 160 and the capillary tube 170.

[0084] The first connecting part 140 is provided near the open end of the outer barrel 110, and the second connecting part 150 is provided near the closed end of the outer barrel 110. In this way, the two ends of the spiral groove 130 are respectively close to the open end and the closed end of the outer barrel 10, thereby effectively extending the overall length of the liquid flow channel and realizing more heat conduction.

[0085] The outer barrel 110, inner barrel 120, liquid inlet pipe 160, and capillary tube 170 are made of metal or plastic.

[0086] In this embodiment, the outer barrel 110, inner barrel 120, liquid inlet pipe 160, and capillary tube 170 are preferably made of metal, which has good heat conduction effect and can improve cooling performance.

[0087] The spiral groove 130 is an arc-shaped recess on the outer wall of the inner barrel 120, thereby reducing the flow resistance of the condensate in the flow channel and improving the flow stability of the condensate.

[0088] A guide edge 180 is provided between adjacent spiral grooves 130, and the guide edge 180 is provided in one or more layers.

[0089] In this embodiment, the guide edge 180 is provided in two layers, and adjacent guide edges 180 form a spaced fit to improve the structural strength of the inner barrel 120.

[0090] The outer side of the guide edge 180 is welded to the inner wall of the inner barrel 120, or they are attached to each other, or they are spaced apart.

[0091] In this embodiment, the outer side of the guide edge 180 is welded to the inner wall of the inner barrel 120.

[0092] The guide edge 180 and the spiral groove 130 have an arc transition, thereby further reducing the flow resistance of condensed liquid in the flow channel.

[0093] The inner barrel 120 has a first support ring 191 and a second support ring 192 on its two end side walls, which are located at the two ends of the spiral groove 130 and are welded to the inner wall of the inner barrel 120 respectively.

[0094] In this embodiment, the first retaining ring 191 and the second retaining ring 192 are welded to the lower and upper sides of the inner wall of the inner barrel 120, which not only improves the assembly stability between the outer barrel 110 and the inner barrel 120, but also avoids leakage problems in the liquid flow channel.

[0095] In this embodiment, the diameters of the first retaining ring 191 and the second retaining ring 192 are the same as the diameter of the guide edge 180.

[0096] In this embodiment, the spiral groove 130 can be formed on the outer wall of the inner barrel 120 by a rotary die casting process.

[0097] The spiral groove 3 can also be formed on the outer wall of the inner barrel 120 by water pressure or mold casting.

[0098] Preferably, the spiral groove 130 is processed on the outer wall of the inner barrel 120 by rotary die casting, so that the spiral groove 130 is directly formed on the outer wall of the inner barrel 120. Example

[0099] Based on the barrel-type evaporator structure disclosed in Embodiment 1, this application discloses another technical solution.

[0100] Referring to Figures 5-13, this smoothie machine includes a main body 900 and a material tank 1000. The material tank 1000 is mounted on the main body 900 and has a feeding port for adding beverage products and a dispensing port 1060 for dispensing. The dispensing port 1060 of the material tank 1000 is located on its end face. A protective shell 1050 is also provided on the end face of the material tank 1000 to conceal the dispensing port 1060. A dispensing operating component 980 with its operating end extending outward is hinged inside the protective shell 1050. A torsion spring is installed at the hinge of the dispensing operating component 980. A sealing cap that cooperates with the dispensing port 1060 is provided on the other end of the dispensing operating component 980. A smoothie outlet 105 is provided on the protective shell 105. 1. A positioning ring 910 is provided on the main body 900. The positioning ring 910 is located on the outer side of the tail end of the barrel evaporator structure 100, and a positioning fastening part 920 and a sealing element 930 are provided on it. The front end of the sealing element 930 is provided with a sealing axial lip 940. The rear end of the material tank 1000 is provided with a circular assembly port 1010. The circular assembly port 1010 is provided with a material tank fastening part 1020 and a material tank axial support part 1030. The material tank 1000 can be detachably fastened to the positioning fastening part 920 through the material tank fastening part 1020. When the material tank 1000 is assembled, it is axially sealed and supported on the sealing axial lip 940 through the material tank axial support part 1030. The barrel evaporator structure 100 extends into the material tank 1000 through the circular assembly port 1010.

[0101] As shown in Figure 7, this embodiment utilizes the cooperation between the material tank fastening part 1020 and the positioning fastening part 920 to allow the material tank 1000 to be disassembled and assembled onto the main body 900, thereby improving the ease of disassembly and assembly of the material tank 1000. This facilitates the user's daily cleaning and maintenance of the material tank 1000 and the barrel-type evaporator structure 100. After the material tank 1000 is assembled, it can be axially sealed against the sealing axial lip 940 through the material tank axial support part 1030, so that the material tank 1000 can be sealed and assembled onto the main body. On the body 900, since the axial support part 1030 of the material barrel and the axial sealing lip 940 are axially sealed, there are no high precision requirements for the shape and size of the circular assembly port 1010. This effectively avoids the disadvantage that the circular assembly port 1010 cannot form a radial seal with the sealing element 930 due to shape deformation or size error. This not only reduces the production process, but also improves the sealing stability between the material barrel 1000 and the main body 900, ensuring that the ice sand in the material barrel 1000 will not leak.

[0102] Referring to Figure 8, the outer ring of the positioning ring 910 has a number of positioning fastening parts 920 in an annular array. The material barrel fastening parts 1020 are arranged in an annular array inside the circular assembly opening 1010. The material barrel fastening parts 1020 are rotated and fastened to the positioning fastening parts 920.

[0103] In this embodiment, the screw-locking engagement between multiple barrel fastening parts 1020 and multiple positioning fastening parts 920 is used to improve the assembly stability between the barrel 1000 and the main body 900. At the same time, since the barrel fastening parts 1020 and the positioning fastening parts 920 are screw-locked, their disassembly and assembly rotation directions are different from the axial sealing support direction between the barrel axial support part 1030 and the sealing axial lip 940. Therefore, after the barrel 1000 is assembled, the axial sealing support stability between the barrel axial support part 1030 and the sealing axial lip 940 can be further improved.

[0104] A guide 950 is provided on the positioning fastening part 920 or the material bucket fastening part 1020, and the material bucket fastening part 1020 and the positioning fastening part 920 are fixed together by the guide 950.

[0105] In this embodiment, the guide portion 950 is inclinedly disposed on the positioning fastening portion 920. The direction of inclination of the guide portion 950 is the same as the direction of rotational fastening of the material bucket 1000, so that the material bucket fastening portion 1020 can be smoothly screwed onto the positioning fastening portion 920, thereby improving the assembly convenience of the material bucket 1000.

[0106] The positioning fastening part 920 or the material bucket fastening part 1020 is provided with a notch 960, and the material bucket fastening part 1020 and the positioning fastening part 920 can be detached and fitted together through the notch 960.

[0107] In this embodiment, the notch 960 is provided on the material bucket fastening part 1020. The material bucket fastening part 1020 can be disassembled and fastened with the positioning fastening part 920 through the notch 960, which is not only convenient to disassemble and assemble, but also secure to fasten.

[0108] The positioning ring 910 has a positioning piece 911 extending from its front end, and the two form an annular groove 912. The seal 930 is positioned on the annular groove 912, thereby improving the assembly stability of the seal 930 and preventing it from falling off.

[0109] The height of the positioning piece 911 is lower than the height of the seal 930, and the sealing axial lip 940 is annularly protruding on the front end face of the seal 930 and located around the positioning piece 911.

[0110] The axial support part 1030 of the material barrel is located in front of the positioning fastening part 920 and is circumferentially protruded in the circular assembly opening 1010 towards the sealing part 930.

[0111] As shown in Figure 6, the barrel evaporator structure 100 is provided with stirring blades 620, the top of the material tank 1000 is provided with a feed inlet, and a feed cover plate 1040 is installed on the feed inlet. The stirring blades 620 are rotatably sleeved on the outer periphery of the barrel evaporator structure 100, and their front and rear ends are respectively positioned between the positioning ring 910 and the inner wall of the front end of the material tank 1000, thereby enabling the stirring blades 620 to rotate at a designated position.

[0112] A drive motor 630 is provided on the main body 900. The drive motor 630 is located at the rear end of the positioning ring 910 and is driven by a drive shaft 610. The drive shaft 610 passes through the positioning ring 910 and the barrel evaporator structure 100 and is driven by the front end of the stirring blade 620. In this way, when the drive motor 630 is working, it drives the stirring blade 620 to rotate on the barrel evaporator structure 100 through the drive shaft 610.

[0113] The smoothie machine includes a main body 900, a baffle 970 that can be detached and installed on the feeding port, and a discharge operation component 980 that is installed on the discharge port 1060. When using the machine, the user can add beverage products into the material tank 1000 by removing and installing the baffle 970, and clean the inside of the material tank 1000. The user can also use the discharge operation component 980 to dispense the smoothie.

[0114] Specifically, the stirring device 600 includes a drive motor 630 and stirring blades 620. The drive motor 630 is mounted on the main body 900 and has a drive shaft 610 connected to it. The drive shaft 610 passes through the barrel evaporator structure 100 and is driven to connect with the stirring blades 620. The stirring blades 620 rotate on the barrel evaporator structure 100 under the drive of the drive motor 630 and the drive shaft 610. The drive motor 630 is controlled by the main control board 500 and drives the stirring blades 620 to rotate on the barrel evaporator structure 100 via the drive shaft 610. During processing, a portion of the beverage product is frozen to the surface of the barrel evaporator structure 100 due to cooling. The rotating stirring blades 620 scrape the frozen portion of the beverage product from the surface of the barrel evaporator structure 100, simultaneously mixing and cooling the beverage product and pushing it towards the front of the container 1000.

[0115] The temperature sensor 700 is preferably disposed on the barrel evaporator structure 100 or the material container 1000, and near the discharge port 1060. In this embodiment, the temperature sensor 700 is disposed on the barrel evaporator structure 100, which can detect the temperature of the beverage product cooled on the surface of the barrel evaporator structure 100. At the same time, since the temperature sensor 700 is close to the discharge port 1060, the temperature detection of the beverage product discharged from the discharge port 1060 is more accurate and better meets the requirements for the soft and hard texture of the slush.

[0116] As shown in Figure 17, the smoothie machine also includes a heat dissipation device 800 connected to the main control board 500. The heat dissipation device 800 is used to dissipate heat from the motor of the barrel evaporator structure 100 and / or the stirring device 600.

[0117] The discharge port 1060 of the material bucket 1000 is located on its end face. The end face of the material bucket 1000 is also provided with a protective shell 1050 to hide the discharge port 1060. A discharge operation member 980 with an operating end extending outward is hinged inside the protective shell 1050. A torsion spring is installed at the hinge of the discharge operation member 980. A sealing cover that cooperates with the discharge port 1060 is provided on the other end of the discharge operation member 980. A sand outlet 1051 is provided on the protective shell 1050.

[0118] When in use, the user applies force to the discharge operating component 980, causing it to rotate via the rotating shaft 990. This overcomes the elastic force of the torsion spring, moving the sealing cover away from the discharge port 1060. The ice sand, propelled by the stirring blades 620, is discharged from the discharge port 1060 into the protective shell 1050, and then discharged from the sand outlet 1051 by gravity. When the force on the discharge operating component 980 disappears (i.e., the user releases the discharge operating component), the discharge operating component 980 automatically resets under the elastic force of the torsion spring, causing the sealing cover to close at the sand outlet 1051 to prevent further discharge of ice sand. Example

[0119] Based on the smoothie machine disclosed in Embodiment 2, this embodiment discloses a smoothie texture control method applicable to the smoothie machine. The barrel evaporator structure 100 is connected to the compressor 200 of the smoothie machine through the liquid inlet pipe 160 and the capillary tube 170 to form a cooling device. The barrel evaporator structure 100 is located inside the material tank 1000 of the smoothie machine. The compressor 200 is installed on the body of the smoothie machine. A refrigeration circuit is formed between the compressor 200 and the barrel evaporator structure 100. The compressor 200 is controlled by the main control board 500 and transports refrigerant to the barrel evaporator structure 100 to promote the cooling of the beverage product in the material tank 1000.

[0120] Referring to Figures 13-17, the method for controlling the texture of the smoothie in this embodiment includes:

[0121] Material hopper 1000 is used to receive beverage products;

[0122] The stirring device 600 stirs the beverage product in the material tank 1000;

[0123] Cooling device, which cools the beverage products in the 1000 container;

[0124] Temperature sensor 700 detects the real-time cooling temperature of beverage products;

[0125] The memory 400 stores different types of beverage products and stores different default working times for different cooling devices for each type of beverage product.

[0126] Control panel 300 receives manual selection of beverage product type and manual adjustment of the cooling device's operating time from the user;

[0127] The main control board 500 is electrically connected to the stirring device 600, the cooling device, the temperature sensor 700, the memory 400, and the control panel 300. It controls the start and stop of the cooling device based on the coordination between the real-time cooling temperature and the default working time of the cooling device, or the coordination between the real-time cooling temperature and the manually adjusted working time of the cooling device.

[0128] This embodiment stores different types of beverage products in the memory 400, and stores the appropriate default working time of the cooling device for each type of beverage product. In addition, the control panel 300 allows users to manually select the beverage product type and manually adjust the default working time of the cooling device. Furthermore, the temperature sensor 700 detects the temperature of the beverage product during the stirring and cooling process, so that the main control board 500 can control the cooling device to stop working by using the default working time or the set working time of the cooling device after the real-time cooling temperature of the beverage product reaches the preset cooling temperature target value. This greatly satisfies the personalized adjustment needs of the texture of the slushie for different types of beverage products. Moreover, the real-time cooling temperature detection and the precise control of the default working time or the set working time of the cooling device can accurately control the texture of the slushie. At the same time, the participation of manual selection can greatly improve the flexibility of the texture adjustment control of the slushie.

[0129] The main control board 500 receives the operating time of the cooling device after manual adjustment by the control panel 300 and generates the set operating time for the cooling device. That is, the user can adjust the default operating time of the cooling device through the control panel 300, and the adjusted default operating time becomes the set operating time for the cooling device.

[0130] The manual adjustment of the cooling device's operating time involves increasing or decreasing the operating time based on the default operating time. In other words, the adjustment of the cooling device's set operating time is based on the default operating time. Users can increase or decrease the time based on the default operating time to allow the main control board 500 to set the cooling device's operating time.

[0131] The operating time of the cooling device can be manually adjusted in increments or decrements of 1-60 seconds or 1-20 minutes.

[0132] When adjusting the operating time of the cooling device, users can add any value within the range of 1-60 seconds or 1-20 minutes to the default operating time of the cooling device, or subtract any value within the range of 1-60 seconds or 1-20 minutes from the default operating time of the cooling device, thereby forming the set operating time of the cooling device.

[0133] After the main control board 500 sets the working time of the cooling device, it updates the working time of the cooling device and makes it the actual working time of the cooling device. After the working time of the cooling device is reached, the main control board 500 controls the cooling device to stop working.

[0134] In this embodiment, the user can choose between the default working time of the cooling device and the set working time of the cooling device. That is, when the user selects the default working time of the cooling device on the control panel 300 and does not manually adjust it, the main control board 500 will control the cooling device to work using the default working time of the cooling device; when the user selects the default working time of the cooling device on the control panel 300 and manually adjusts it, the main control board 500 will control the cooling device to work using the set working time of the cooling device.

[0135] The cooling device's set operating time and default operating time both start from when the real-time cooling temperature of the beverage product detected by the temperature sensor 700 reaches the target cooling temperature value, and end after the countdown is complete.

[0136] The target cooling temperature is 5 degrees to -10 degrees, and it is stored in memory 400.

[0137] The preferred target cooling temperature in this implementation is 3-0 degrees Celsius, at which point the beverage product is not frozen. At the same time, the delayed operation of the cooling device allows the beverage product to continue cooling and form a slush.

[0138] The memory 400 stores various types of beverage products, each with a different default operating time for the cooling device and a unified target cooling temperature value.

[0139] Different types of beverage products correspond to different default operating times of the cooling device. Without any manual adjustment by the user, after different types of beverage products are cooled to a uniform target cooling temperature, the main control board 500 will control the cooling device according to the default operating time of the cooling device corresponding to the beverage product.

[0140] The method for controlling the texture of smoothies in this embodiment includes the following steps:

[0141] I) Place the beverage product in container 1000;

[0142] II) Select the corresponding type of beverage product via control panel 300;

[0143] III) The memory 400 retrieves the default operating time of the cooling device for the corresponding type of beverage product, while the control panel 300 displays the type of beverage product and the default operating time of the cooling device.

[0144] IV) The main control board 500 receives the user's adjustment of the default working time of the cooling device and forms the set working time of the cooling device. At the same time, the control panel 300 displays the set working time of the cooling device.

[0145] V) The main control board 500 detects the real-time cooling temperature of the beverage product during the stirring and cooling process and the default working time / set working time of the cooling device based on the temperature sensor 700 of the smoothie machine, so as to control the stirring device 600 to stir the beverage product in the material tank 1000 and control the cooling device to cool the beverage product in the material tank 1000.

[0146] VI) The main control board 500 receives the real-time cooling temperature, and the real-time cooling temperature value reaches the target cooling temperature value;

[0147] VII) The main control board starts a countdown for the default working time or the set working time of the cooling device from time 500.

[0148] VIII) When the default working time or the set working time of the cooling device ends, the main control board 500 controls the cooling device to stop working.

[0149] Referring to Figures 5 and 6, specifically, the user places the beverage product into the inlet, and then selects the type of beverage product to be processed via the control panel 300. For example, the user selects "orange juice." Once the beverage product is placed in the container 1000, the user can provide input, such as pressing the "smoothie" button. The main control board 500 then begins processing the beverage product based on the "smoothie" setting. The main control board 500 may include an activation device 600 for stirring and / or a cooling device for cooling. To adjust the temperature under specific settings associated with the "smoothie," the main control board 500 starts or stops the cooling device from cooling the beverage product based on the default or set operating time of the cooling device.

[0150] Temperature sensor 700 continuously monitors the cooling temperature of the beverage product in container 1000. When the real-time cooling temperature of the beverage product reaches the target cooling temperature, the main control board 500 starts the countdown of the default working time or the set working time of the cooling device. At this time, the amount of soft and hard texture of slush and / or ice particles formed in the beverage product corresponds to the extended cooling temperature of the beverage product. That is, the longer the cooling device works, the lower the temperature, the larger the amount of particles (and / or the larger the particle size) and / or the more viscous the beverage product.

[0151] When the machine leaves the factory, it stores different default operating times for different types of beverage products to meet the general cooling needs of users. In addition, users can adjust the default operating time of the cooling device through the control panel 300, thereby setting the operating time of the cooling device so that users can adjust the temperature and / or texture of the beverage product to a more desired temperature and / or texture.

[0152] The memory 400 is located on the main control board 500.

[0153] In this embodiment, the memory 400 is capable of storing multiple beverage product preparation and / or processing instruction programs associated with multiple beverage product processing sequences. Such beverage preparation and / or processing instruction programs may include instructions for the main control board 500 to perform the following operations: start or stop the stirring device 600; start or stop the cooling device to regulate the temperature of the beverage products processed in the hopper 1000; operate the stirring device 600 at certain times during a specific beverage product processing sequence; operate the stirring device 600 at certain speeds during certain time periods of the formula; the control panel 300 issues prompting instructions; and the main control board 500 responds, acts, and / or inputs from the memory 400.

[0154] The main control board 500 is equipped with an adjustable DC voltage circuit, which outputs different voltage signals and controls the drive motor 630 to output different speeds through different voltage signals.

[0155] In this embodiment, an adjustable DC voltage circuit is provided on the main control board 500, and different voltage signals are output by the control of the adjustable DC voltage circuit. The main control board 500 then controls the drive motor 630 to output different speeds according to the different voltage signals, so that the drive motor 630 can rotate at least fast and slow speeds, so that the stirrer can stir the ice cream at at least two different speeds.

[0156] In actual use, the fast-rotating mixer can speed up the mixing of ice cream, which not only reduces cooling blockage but also improves the uniformity and texture of the ice cream. The slow-rotating mixer can slow down the dispensing speed of the ice cream, ensuring a stable dispensing speed and reducing the problem of ice cream falling off due to excessive dispensing speed, thus greatly improving the user experience.

[0157] The main control board 500 is equipped with at least two voltages, large and small, for user use. The drive motor 630 can rotate quickly or slowly by selecting the voltage through the control panel 300.

[0158] When mixing the ice cream, the user selects a high voltage via the control panel 300, which drives the motor 630 to rotate rapidly, and the mixer quickly stirs the ice cream. When discharging the ice cream, the user selects a low voltage via the control panel 300, which drives the motor 630 to rotate slowly, and the mixer slowly stirs the ice cream to complete the slow discharging of the ice cream.

[0159] The voltage settings on the control panel 300 are 10V-15V and 15V-24V.

[0160] In this embodiment, the small voltage is 10V, and the large voltage is 15V or 24V.

[0161] The adjustable DC voltage circuit includes a switching transistor that switches the input voltage to a high-frequency pulse signal, an input filter, a rectifier and filter for a stable output DC voltage, a pulse transformer 510 for converting the operating voltage, a power driver chip connected to the switching transistor, and a PWM debugging optocoupler feedback loop 520.

[0162] In this embodiment, the adjustable DC voltage circuit works as follows: the input voltage is switched to a high-frequency pulse signal by the switching action of the switching transistor, and then converted to the required voltage level by the pulse transformer 510. Finally, after rectification and filtering, a stable DC voltage is output. The output DC voltage is then controlled by the PWM debugging optocoupler feedback loop 520 to automatically adjust the output DC voltage, i.e., 10V, 15V or 24V, thereby achieving the speed regulation effect of the drive motor 630, that is, the speed regulation purpose is achieved by changing the working voltage of the drive motor 630.

[0163] The control panel 300 is equipped with a motor drive control circuit, which is electrically connected to the drive motor 630. The motor drive control circuit consists of a switching MOSFET and a current sampling resistor, and is equipped with an R7 sampling resistor for sampling the current of the drive motor 630.

[0164] In this embodiment, the working principle of the motor drive control circuit is as follows: when the MOS control terminal signal is high, the drive motor 630 is powered on and works; when the MOS control terminal signal is low, the drive motor 630 is powered off and stops working; the sampling resistor R7 is responsible for sampling the current of the drive motor 630, which is then processed by the processor to realize the stall protection of the drive motor 630.

[0165] The main control board 500 is equipped with a 5V voltage regulator circuit, which consists of a 5V voltage regulator module and a filter capacitor.

[0166] In this embodiment, the working principle of the 5V voltage regulator circuit is: by comparing the output voltage and the reference voltage and adjusting the output current, the output voltage is kept stable, thereby achieving the effect of 5V voltage regulation.

[0167] The main control board 500 is equipped with a temperature sampling circuit. The temperature sampling circuit consists of a 100K pull-up resistor and an NTC temperature sensor 700 forming a voltage divider circuit, and outputs a temperature analog electrical signal to the main control board 500.

[0168] In this embodiment, the working principle of the temperature sampling circuit is as follows: the temperature is measured using an NTC temperature sensor 700, then the temperature signal is converted into an electrical signal, a voltage divider circuit is used to amplify the electrical signal to a range that can be read by the processor, a filter is used to reduce noise interference, and finally the processor calculates the temperature value to detect the temperature of the ice cream during stirring.

[0169] The main control board 500 is mounted on the main body 900, and the control panel 300 is mounted on the main body 900 and includes a button area and a display area. The button area includes touch buttons and a rotary encoder, while the display area includes a display screen, a digital tube, and LED beads. The main control board 500 is electrically connected to the touch buttons and rotary encoder to control the functions, cooling time, and voltage selection of the ice cream machine. The display driver chip of the main control board 500 is electrically connected to the control panel 300 to control the display screen, digital tube, and LED beads to display status information, including, for example, the temperature of the beverage product in the hopper 1000, an indicator of the currently implemented recipe and / or program, the default working time of the cooling device associated with the progress of the ongoing and / or currently implemented recipe and / or program, and the set working time of the cooling device. In addition, the display area can also provide the user with indicators and / or warnings about, for example, when the recipe is completed or when the user is expected to perform actions associated with handling the beverage product. The display area can also include optional menus for different types of beverage products (e.g., recipes) and / or programs, such as, but not limited to, smoothies, ice cream, melted snow, and the like. The button area allows for dispensing of the prepared slushies, ice cream, snow melt water, and similar products, as well as issuing cleaning commands for the material tank 1000.
