Description

TECHNICAL FIELD

[0002] Cold drink equipment can generally process liquid raw materials into ice-shaped products (such as smoothies, ice cream, etc.), which generally includes a refrigeration system and a material preparation system, wherein the refrigeration system includes a compressor, a condenser and an evaporator, and the material preparation system includes a motor rotating device and a rotating scraper. In use, first, pour the raw materials such as beverages, milk, etc. into the feed cover, then through the evaporator arranged in or outside the material preparation cylinder, the raw materials in the feed cover are subjected to refrigeration heat exchange, and with the progress of the refrigeration process, the raw materials gradually form a solid-liquid mixture, at the same time, the motor rotating device drives the rotating scraper to stir the solid-liquid mixture in the feed cover to prevent the solid-liquid mixture from forming ice blocks, ensuring that the solid-liquid mixture can form smoothies or ice cream products.

[0003] However, some traditional cold drink equipment uses a shaded pole motor to stir the solid-liquid mixture, and due to the low speed regulation accuracy and speed regulation response efficiency of the shaded pole motor, the stirring effect is greatly affected, resulting in that it cannot be applied to scenes with high speed regulation requirements and changes, such as being unable to dynamically adjust the stirring speed according to the production requirements of different products (such as smoothies or ice cream), and only being able to produce a single type of frozen dessert.

[0004] Secondly, the manufacturing equipment with single smoothie function cannot manufacture ice cream products with smaller ice crystal particles and delicate taste, one reason is that the particles of ice cream products are smaller and more likely to be hidden in small corners, and the front end of the cylinder body of the smoothie manufacturing equipment is usually straight or flat, without corresponding flow guide structure, ice cream products with smaller ice crystal particles are easy to stay at the front end of the cylinder body, thus it is difficult to produce normal backflow circulation, and further affect the subsequent stirring efficiency.

[0010] As an improvement to the above solution, the upper or upper-middle part of the cold drink equipment also includes a driving heat dissipation area, which is located between the stirring area and the driving heat dissipation area.

[0011] As an improvement to the above solution, the main control device includes a main controller and a control panel. The control panel is connected to the main controller and is used to send the user-inputted function control commands to the main controller.

[0012] As an improvement to the above solution, the material preparation cylinder includes a flow guide, which is disposed at one end of the material preparation cylinder near the discharge mechanism.

[0027] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 3 As shown in the figure, a specific embodiment of this utility model 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 disposed on the body 1. The feeding and discharging mechanism 4 includes a material preparation cylinder 41, a discharging mechanism 42 disposed at one end of the material preparation cylinder 41 and a temperature sensor 43 disposed in the material preparation cylinder 41. The material preparation cylinder 41 can contain raw materials for making cold drinks and solid-liquid mixtures after molding. The material preparation cylinder 41 is provided with a feeding port 441, through which raw materials are poured in. The discharging mechanism 42 is used to output the solid-liquid mixture after molding, such as shaved ice or ice cream.

[0029] The refrigeration mechanism 2 is used to cool the material preparation cylinder 41, so that the material is in a low-temperature forming environment. The stirring mechanism 3 includes a variable speed motor 31 and a stirring element 32. The variable speed motor 31 is connected to the stirring element 32. The stirring element 32 is disposed in the material preparation cylinder 41. The variable speed motor 31 can drive the stirring element 32 to rotate in the material preparation cylinder 41 to stir the material. The variable speed motor 31 can achieve stepless speed regulation, a wide speed range, and good smoothness. It can effectively realize speed regulation work for different functions or under different conditions, such as smoothies and ice cream with different speed regulation requirements. Ice cream has a higher stirring rate requirement than smoothies.

[0030] The temperature sensor 43 is connected to the main control device 5 and is used to detect the temperature data in the mixing cylinder 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. It is used to control the refrigeration mechanism 2 to provide a preset function mode refrigeration environment for the mixing space of the mixing cylinder 41 according to the temperature data and the input mixing function command, and to control the variable speed motor device 31 to adjust the speed and rotation direction of the stirring piece 32 according to the preset function mode to perform the mixing work of different cold beverage products. For example, when the input slush or ice cream function command is given, the refrigeration mechanism 2 can be controlled to perform the corresponding function temperature refrigeration work according to the detected temperature data, and the variable speed motor device 31 can be controlled to perform the corresponding function stirring work to ensure that the raw materials are cooled evenly and mixed with the air, improve the shape of the ice cream or slush and ensure its forming hardness, thereby realizing the making of slush or ice cream. Furthermore, by adjusting different working temperatures and stirring modes, the mixing function of different cold beverage products can be realized to meet the user's multi-purpose needs.

[0031] Preferably, different raw material preparation scenarios have different discharge stirring speeds, so that rapid discharge can be carried out for different raw material preparation scenarios during discharge, which can prevent material accumulation and improve discharge efficiency.

[0032] Specifically, such as 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 disposed in the material preparation cylinder 41, and a temperature sensor is installed on the evaporator. The stirring element 32 surrounds the evaporator 23. The two ends of the compressor 21 are connected to the inlet end of the condenser 22 and the outlet end of the evaporator 23 respectively via pipes. The outlet end of the condenser 22 is connected to the inlet end of the evaporator 23. When the compressor 21 is operating in refrigeration mode, it can supply cooling to the evaporator 23, thereby cooling the internal space of the material preparation cylinder 41 and the materials through the evaporator 23. The stirring element 32 mounted on the evaporator 23 agitates the materials, ensuring the stable operation of the low-temperature material preparation process for smoothies or ice cream.

[0033] Furthermore, such as Figure 1 , Figure 3 and Figure 5 As shown, the upper or 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 element 32, and the material preparation cylinder 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. The mounting frame 311 is installed on the end of the material preparation cylinder 41 away from the discharge mechanism 42. The variable speed motor 312, reducer 313, and coupling 314 are sequentially connected and mounted on the mounting bracket 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 element 32. The variable speed motor 312 can drive the stirring element 32 to stir the material in the material preparation cylinder 41, achieving stepless stirring speed regulation to meet the requirements of high speed regulation accuracy and various scenarios. The variable speed motor 312 is inclined inside the machine body 1 to reduce its volume and thus reduce the volume of the machine body 1.

[0034] The upper or upper-middle part of the cold drink equipment also includes a drive heat dissipation zone 8. The drive zone 7 is located between the stirring zone 6 and the drive heat dissipation zone 8. The drive heat dissipation zone 8 includes a drive cooling fan, which can extract the working heat in the drive zone to the outside of the machine body to reduce the working temperature of the drive zone.

[0035] The lower part of the cold drink equipment is provided with a refrigeration zone 9, which is equipped with a compressor 21, a condenser 22 and a cooling fan 91. The cooling fan 91 is located on one side of the condenser 22 and is used to extract the working heat in the refrigeration zone 9 to the outside of the machine body in order to reduce the working temperature of the refrigeration zone.

[0036] Among them, the variable speed motor 312 is preferably a variable speed DC motor, but is not limited to this.

[0037] Preferably, such as 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 user-inputted function control commands to the main controller 51 to achieve different functions. In other embodiments, the main control device 5 may also include a wireless communication terminal. The main controller 51 can be connected to an external remote controller or mobile terminal through the wireless communication terminal to achieve wireless control functions.

[0038] To facilitate the flow of the formed product at the front end of the material preparation cylinder 41, such as Figure 1 and 3 As shown, the material preparation cylinder 41 includes a flow guide 411, which is located at one end of the material preparation cylinder 41 near the discharge mechanism 42, i.e., the front end of the material preparation cylinder 41. The flow guide 411 gradually slopes from the upper part of the material preparation cylinder 41 toward the discharge mechanism 42. Under the guiding effect of the inclined flow guide 411, the formed product can flow from the side of the discharge mechanism 42 toward the upper part of the material preparation cylinder 41 without affecting the product flowing from the middle of the material preparation cylinder 41 to the discharge mechanism 42. Under the continuous extrusion pressure, the ice slush located in the flow guide 411 can continuously flow back from the upper part of the material preparation cylinder 41 to the middle part, thereby forming a cycle. Smaller ice cream particles tend to get stuck in smaller corners. However, because the inner wall of the guide section 411 forms a concave surface, the engagement between the concave surface and the mixing cylinder 41 is less likely to create a corner where ice cream particles can get stuck than the engagement between the flat surface and the mixing cylinder 41. Therefore, it is more conducive to the smooth flow of ice cream with smaller ice crystal particles. Thus, the cold drink equipment of this invention can be used for both smoothies and ice cream. By recirculating the smoothies and ice cream, the stirring efficiency and stirring effect can be improved.

[0039] Furthermore, such as Figure 1 and Figure 4A transition connection 412 is provided between the outer wall of the material preparation cylinder 41 and the inlet 441 of the material preparation cylinder 41. The transition connection 412 is used to form a transition connection between the inlet 441 and the material preparation cylinder 41. The transition connection 412 gradually extends from the outer wall of the material preparation cylinder 41 towards the inlet 441. After the raw material freezes to form a solid-liquid mixture, the solid-liquid mixture can be contained in the transition connection 412 and gradually stirred and pushed from the transition connection 412 to the outlet 418. The transition connection 412 increases the containing volume and facilitates the return of the solid-liquid mixture from the top of the material preparation cylinder 41.

[0040] Specifically, the inner wall of the guide section 411 is a concave continuous curved surface. The use of a concave continuous curved surface allows the slush and ice cream to flow smoothly back towards the upper part of the mixing cylinder 41 at the position of the dispensing mechanism 42, which is beneficial for the reflux of the solid-liquid mixture and forms a circulation of the solid-liquid mixture in the mixing cylinder 411.

[0041] In some embodiments, the transition connection 412 is an arc-shaped transition or an inclined transition. The arc-shaped or inclined transition shape allows the solid-liquid mixture to smoothly move gradually from the inlet 441 to the middle of the feeding cylinder 411, and then gradually to the vicinity of the outlet 418. Furthermore, the surface of the transition connection 412 is a smooth curved surface. This smooth curved surface reduces the friction of the solid-liquid mixture in the transition connection 412, thereby facilitating the movement of the solid-liquid mixture in the transition connection 412 and simplifying stirring and feeding. It also reduces the likelihood of material accumulation or stagnation of the solid-liquid mixture in the transition connection 412.

[0042] In some embodiments, the width of the transition connection 412 gradually increases from the outer wall of the material preparation cylinder 41 towards the feed inlet 441, and the transition connection 412 forms a gradually converging channel in the direction away from the feed inlet 441, so as to facilitate the concentrated movement of the solid-liquid mixture to the middle of the material preparation cylinder 41. In other embodiments, the width of the transition connection 412 gradually decreases from the outer wall of the material preparation cylinder 41 towards the feed inlet 441, so that the position of the transition connection 412 can accommodate more solid-liquid mixture.

[0043] Preferably, the outer contour of the cross-section of the material preparation cylinder 41 is a circle, ellipse, or quasi-ellipse formed by a smooth curve. A quasi-ellipse refers to a closed curve shape with a major and minor axis, but differing from a standard ellipse in terms of curvature and symmetry at the edges. This cross-sectional outer contour increases the storage space of the material preparation cylinder 41. Simultaneously, the closed contour formed by the smooth curve reduces the frictional force of the solid-liquid mixture on the inner wall of the material preparation cylinder 41, thereby reducing material accumulation and stagnation, promoting uniform mixing, and improving the mixing effect.

[0044] like Figure 4 As shown, the material preparation cylinder 41 has a side end face 413 at one end near the discharge mechanism 42. The discharge mechanism 42 is disposed on the side end face 413. The compressed solid-liquid mixture will concentrate on the side end face 413, and the upper part of the side end face 413 is connected to the lower part of the guide part 411.

[0045] In this embodiment, the upper part of the side end face 413 is tangentially connected to the lower part of the guide part 411. Along the junction of the side end face 413 and the guide part 411, the solid-liquid mixture can smoothly transfer from the side end face 413 to the upper part of the material preparation cylinder 41. The connection line between the side end face 413 and the guide part 411 is a first connection line 414. The solid-liquid mixture undergoes a first turn in the first connection line 414, enabling the solid-liquid mixture to transfer from the side end face 413 to the upper part of the material preparation cylinder 411.

[0046] The side wall of the material preparation cylinder 41 is provided with a cylinder body surface 415, which is the main side wall of the material preparation cylinder 41. The cylinder body surface 415 is connected to the upper part of the guide part 411. In this embodiment, the cylinder body surface 415 is tangentially connected to the upper part of the guide part 411. 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 cylinder body surface 415. The junction of the cylinder body surface 415 and the guide part 411 is a second junction 416. The solid-liquid mixture undergoes a second turn in the second junction 416, so that the solid-liquid mixture can flow back to the middle of the material preparation cylinder 411 to form a cycle.

[0047] In this embodiment of the invention, there are two second-phase wires 416, which are symmetrically inclined and bent from the top of the material preparation cylinder 41 towards both sides of the guide section 411. The two second-phase wires 416151 guide the movement of the solid-liquid mixture from both sides of the guide section 411. Simultaneously, the inclined and bent arrangement reduces the space where solid-liquid mixtures with small ice crystal particles, such as those found in ice cream, stagnate in the guide section 411, thus improving the smoothness of the solid-liquid mixture's return flow.

[0048] Furthermore, one end of each of the two second phase wires 416 intersects, and the other end bends and extends towards both sides of the guide section 411 and connects to both ends of the first phase wire 414. Along the reflux direction of the solid-liquid mixture, the two second phase wires 416 converge and intersect from both ends of the first phase wire 414 towards the upper part of the feeding cylinder 41, so that when the guide section 411 moves, the solid-liquid mixture can be concentrated and converged to the center of the upper part of the feeding cylinder 41 to form a more concentrated reflux path. In this way, the overall cross-section of the refluxed solid-liquid mixture is smaller, and under a certain flow rate, the reflux velocity of the solid-liquid mixture is increased, which can accelerate the reflux speed and also allow the solid-liquid mixture in the stirring state to move smoothly to the side end face 413, ensuring reflux efficiency and stirring effect.

[0049] like Figure 1 , Figure 3 and Figure 4 As shown, the material preparation cylinder 41 also includes a feeding section 44, which is disposed on the transition connection section 412. The feeding port 441 is disposed on the feeding section 44. The transition connection section 412 protrudes upward from the cylinder body surface 415 of the material preparation cylinder 41 and is disposed at one end of the material preparation cylinder 41 away from the discharge mechanism 42, so as to expand the space for accommodating raw materials, making it easier to enter more raw materials, and allowing the raw materials after entering to be fully frozen and stirred.

[0050] The transition connection part 412 is provided with a feeding chamber 417, which is connected to the storage space of the material preparation cylinder 41. When the raw material is poured in, the raw material first enters the feeding chamber 417 and then enters the storage space. The diameter of the longitudinal section of the feeding chamber 417 is larger than the maximum diameter of the longitudinal section of the storage space, which increases the volume of raw material and solid-liquid mixture that the material preparation cylinder 411 can accommodate.

[0051] Furthermore, the discharge mechanism 42 includes a discharge hopper 421, a handle 422, and a discharge valve 423. The discharge hopper 421 is disposed on the side end face 413, and the side end face 413 is provided with a discharge port 418, which can communicate with the discharge hopper 421. One side of one end of the handle 422 is hinged to the discharge hopper 421, and the other side of one end of the handle 422 is hinged to the discharge valve 423. The handle 422 can swing relative to the discharge hopper 421. During the swinging process of the handle 422, the handle 422 can drive the discharge valve 423 to rise or fall to open or close the discharge hopper 421, thereby achieving the effect of discharging or closing the discharge hopper 421.

[0052] In summary, this utility model can control the refrigeration mechanism and variable speed motor to perform stepless speed regulation of slush or ice cream making work based on the temperature data and the input material making function command. By adjusting different working temperatures and stirring speeds, it can achieve the two-in-one material making function of slush and ice cream, thus meeting the user's need for multiple uses in one machine.

[0053] At the same time, different motor stirring control logics are used under different working conditions to avoid local lumps or large particles in the material during production, so as to maintain the overall shape and hardness of the material, thereby improving the taste of the finished product and meeting the actual needs of users.

[0054] Secondly, during the stirring process, the solid-liquid mixture moves to the front end of the mixing cylinder. In order to facilitate the smooth return of the solid-liquid mixture at the front end of the mixing cylinder, the mixing cylinder also includes a guide section. The guide section gradually tilts from the upper part of the mixing cylinder towards the discharge mechanism. In this way, the guide section can guide the solid-liquid mixture to move upward to the upper part of the mixing cylinder and tilt to move to the middle part of the mixing cylinder, thereby completing the return of the slush. Since the inner wall of the guide section forms a concave surface, the concave surface is not easy to form corners that are difficult to hide. Therefore, smaller particles such as ice cream are not easy to be retained in the guide section, which facilitates the return of the small particle solid-liquid mixture. This makes it suitable for the return of slush and ice cream and improves the stirring efficiency and stirring effect.

[0055] Finally, it should be noted that the above-described embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this utility model.
