[0001] This utility model relates to the technical field of equipment for preparing ice cream, and in particular to an ice cream machine with a novel stirring structure. Background Technology

[0002] Ice cream is a popular summer treat, and its production has evolved from traditional handmade methods to the more common machine-made methods. Machine-made ice cream has become the mainstream method due to its high efficiency, good taste, and consistent quality.

[0003] In the process of making ice cream in an ice cream machine, the ingredients need to be mixed with water, milk, etc., and then sent to the evaporator for preparation. Therefore, the uniformity of the mixing of the ingredients affects the taste of the product. Existing ingredient mixing devices generally use conventional rotating blade mixing methods. The drawback of this method is that the blades cannot mix the ingredients at the bottom, resulting in insufficient mixing and ultimately affecting the taste of the ice cream. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ice cream machine with a novel stirring structure to solve the technical problem of insufficient stirring of raw materials by existing stirring mechanisms.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An embodiment of this utility model provides an ice cream machine with a novel stirring structure, comprising: a chassis, a stirring assembly and a refrigeration assembly disposed within the chassis, and a control valve assembly provided on the chassis;

[0007] The refrigeration assembly includes: a compressor, a condenser connected to the compressor, and an evaporator connected to the condenser, wherein the evaporator has at least one preparation chamber for preparing ice cream, and the control valve assembly is connected to one end opening of the preparation chamber;

[0008] The stirring assembly includes: a stirring tank, a stirring element disposed in the stirring tank, and a stirring drive element for driving the stirring element to rotate;

[0009] The stirring component includes a shaft section, an outer wall stirring section connected to the shaft section, and a scraper section connected to the bottom side wall of the shaft section, with the bottom edge of the scraper section abutting against the bottom wall of the mixing tank.

[0010] The outer wall of the shaft cylinder is provided with a disc near the bottom, the bottom edge of the stirring part extends to the upper surface of the disc, and the scraper is connected to the lower surface of the disc.

[0011] The stirring part is a stirring blade, which extends axially along the shaft cylinder.

[0012] The stirring blades are arranged such that their radial width gradually increases from the top end to the bottom end of the shaft cylinder.

[0013] The disc portion is also provided with several through holes, which are vertically away from the scraper portion.

[0014] The stirring section and the scraper section are evenly spaced.

[0015] The stirring drive includes: a rotating shaft, a driven pulley connected to the rotating shaft, a synchronous belt connected to the driven pulley, and a motor connected to the synchronous belt. The rotating shaft passes through the bottom wall of the stirring tank, and the driven pulley is located outside the stirring tank.

[0016] The mixing tank is provided with at least two mixing chambers, and each mixing chamber is provided with a mixing component.

[0017] The evaporator has the same number of production chambers as the stirring chamber.

[0018] The evaporator is also connected to a conveying assembly, which includes a drive motor, a gear module driven by the drive motor, and a scraper driven by the gear module to rotate. The scraper extends into the production chamber from the rear end of the production chamber and rotates under the drive of the drive motor to push the produced ice cream to the control valve assembly.

[0036] Ice cream is a popular summer treat, and its production has evolved from traditional handmade methods to the more common machine-made methods. Machine-made ice cream has become the mainstream method due to its high efficiency, good taste, and stable quality. In the ice cream making process, the ingredients need to be mixed with water, milk, etc., and then sent to an evaporator for processing. Therefore, the uniformity of the mixing of the ingredients affects the taste of the product. Existing ingredient mixing devices generally use conventional rotating blade mixing methods. The drawback of this method is that the blades cannot effectively mix the ingredients at the bottom, resulting in insufficient mixing and ultimately affecting the taste of the ice cream. Therefore, based on the above requirements, this embodiment provides an ice cream machine 100 with a novel mixing structure.

[0037] Please see Figures 1 to 11 This embodiment discloses a novel ice cream machine 100 with a stirring structure, which includes: a housing 1, a stirring assembly 2 and a refrigeration assembly disposed in the housing 1, and a control valve assembly 6 disposed on the housing 1;

[0038] The refrigeration assembly includes: a compressor 3, a condenser 4 connected to the compressor 3, and an evaporator 5 connected to the condenser 4. The evaporator 5 has at least one preparation chamber for making ice cream, and the control valve assembly 6 is connected to one end opening of the preparation chamber.

[0039] The stirring assembly 2 includes: a stirring tank 21, a stirring element 22 disposed in the stirring tank 21, and a stirring drive element for driving the stirring element 22 to rotate;

[0040] The stirring component 22 includes a shaft cylinder 2221, a stirring part 2222 connected to the outer wall of the shaft cylinder 2221, and a scraper part 2224 connected to the bottom side wall of the shaft cylinder 2221. The bottom edge of the scraper part 2224 abuts against the bottom wall of the mixing tank 21.

[0041] The ice cream machine 100 with the novel stirring mechanism of this embodiment includes a compressor 3, a condenser 4 connected to the compressor 3, and an evaporator 5 connected to the condenser 4. The compressor 3, condenser 4, and evaporator 5 together form a conventional refrigeration system, which are connected by a pipeline for transporting refrigerant. By circulating the refrigerant (i.e., the cooling medium), ice cream is prepared in the making chamber of the evaporator 5. In this embodiment, the evaporator 5 has two making chambers, namely a first making chamber 51 and a second making chamber 52. Depending on the refrigeration power, one set of refrigeration components can be used to provide cooling energy to multiple making chambers simultaneously, thereby simplifying the equipment size and preparing multiple or more flavors of ice cream at the same time.

[0042] The mixing assembly 2 includes a mixing element 22, which features an innovative structural design. Its mixing section 2222 is located on the side wall of the shaft cylinder 2221, and the scraper section 2224 is located near the bottom of the shaft cylinder 2221. When the mixing element 22 is rotated in a controlled manner to mix the raw materials, the mixing section 2222 mixes the upper layer of materials in the mixing tank 21, while the scraper section 2224 at the bottom simultaneously scrapes the raw materials that have settled at the bottom of the mixing tank 21, preventing the raw materials from accumulating at the bottom of the mixing tank 21 and thus ensuring thorough mixing. Compared to existing blade mixing structures, the mixing element 22 in this embodiment provides more uniform mixing, and in particular, prevents the raw materials from settling at the bottom, ensuring thorough mixing.

[0043] Please refer to it again. Figure 10 and Figure 11 The outer wall of the shaft cylinder 2221 near the bottom is also provided with a disc portion 2223. The bottom edge of the stirring portion 2222 extends to the upper surface of the disc portion 2223, and the scraper portion 2224 is connected to the lower surface of the disc portion 2223. The disc portion 2223 is perpendicular to the shaft cylinder 2221, and the disc portion 2223 extends vertically outward from the side wall of the shaft cylinder 2221 near the lower end. The corresponding stirring portion 2222 is connected to the side wall of the shaft cylinder 2221 in the axial direction, and the bottom of the stirring portion 2222 is connected to the disc portion 2223.

[0044] The stirring section 2222 is a stirring blade, which extends axially along the shaft cylinder 2221. The stirring section 2222, with its blade-like structure, agitates the raw materials within the stirring tank 21 by rotation. In other embodiments, the stirring blade may be a stirring structure that is narrower at the top and wider at the bottom.

[0045] The stirring blades are arranged such that their radial width gradually increases from the top to the bottom of the shaft cylinder 2221. That is, as... Figure 11As shown, the stirring plate is a triangular plate, with its two shorter sides connected to the shaft cylinder 2221 and the disc 2223 respectively, and its longest side inclined in the vertical direction. When the stirring member 22 rotates and stirs the material, more solid material is located at the bottom of the mixing tank 21. This bottom position requires greater stirring force, while the material in the upper layer mixes with the material at the bottom under its own weight. Therefore, the stirring part 2222 is set as a triangular plate structure to adapt to the distribution of the material and improve its stirring efficiency.

[0046] Furthermore, the disc portion 2223 is provided with several through holes 2225, which are vertically oriented away from the scraper portion 2224. The through holes 2225 are arc-shaped holes, which help the raw material at the scraper portion 2224 to overflow upwards during the stirring process, preventing excessive raw material from being squeezed under the disc portion 2223, thus avoiding the risk of the stirring component 22 getting stuck.

[0047] In this embodiment, the stirring part 2222 and the scraper part 2223 are evenly spaced, and the stirring component 22 is an integrally formed structure.

[0048] Please refer to it again. Figure 10 The stirring component 22 further includes a stirring drive component, which includes: a rotating shaft 221 and a driven pulley 223 connected to the rotating shaft 221, a synchronous belt (not shown in the figure) and a motor 224 connected to the synchronous belt. The rotating shaft 221 passes through the bottom wall of the stirring tank 21, and the driven pulley 223 is located outside the stirring tank 21. A stirring unit 222 is sleeved on the rotating shaft 221. The stirring unit 222 includes an integral structure formed by the aforementioned shaft cylinder 2221, stirring section 2222, scraper section 2223 and disc section 2224. The motor 224 is fixedly connected to the shell of the evaporator 5. Each stirring unit 222 is provided with a stirring drive component that is linked to it, for distributed control of its start and stop, so as to realize independent stirring of each stirring chamber.

[0049] The mixing tank 21 is provided with at least two mixing chambers. In this embodiment, the mixing chambers are a first mixing chamber 211 and a second mixing chamber 212. Each mixing chamber is provided with a mixing component 22.

[0050] Correspondingly, the evaporator 5 has the same number of production chambers as the stirring chambers. In this embodiment, there are two stirring chambers, and correspondingly two production chambers. Each stirring chamber provides the stirred raw material to one of the production chambers.

[0051] Please refer to it again. Figure 9The evaporator 5 is also connected to a conveying assembly 9, which includes a drive motor 91, a gear module 94 driven by the drive motor 91, and scrapers 53 driven by the gear module 94. The scrapers 53 extend from the rear end of the production chamber into the production chamber and rotate under the drive of the drive motor 91 to push the produced ice cream to the control valve assembly 6. The output shaft of the drive motor 91 is connected to a transmission belt 92, and the input end of the gear module 94 is provided with a driven pulley 93. The drive motor 91 is fixedly connected to the housing 1. Since this embodiment has two production chambers and two corresponding scrapers 53, and both sets of production chambers and scrapers 53 are driven by the same set of drive motors 91, the function of the gear module 94 is to convert a single output into two rotating outputs, with each rotating output shaft driving one of the scrapers 53. This design simplifies the structure and facilitates the miniaturization of the ice cream machine.

[0052] Please refer to it again. Figure 6 and Figure 8 The first stirring chamber 211 and the second stirring chamber 212 are also provided with liquid inlet pipes 24, which are connected to the liquid storage tank 7, which is located inside the machine casing 1.

[0053] Please refer to it again. Figure 4 and Figure 5 The refrigeration components and stirring components 2 are distributed inside the casing 1 as follows: the compressor 3, condenser 4, and liquid storage tank 7 are all located at the bottom of the casing 1, the evaporator 5 is located in the middle of the casing 1, and the stirring components 2 are located above the evaporator 5. The drive motor 91 of the conveying component 9 is fixedly connected to the side wall of the casing 1, and the gear module 94, etc., are located in the rear end space of the evaporator 5. This distribution method is compact and reasonable, making full use of the internal space of the casing 1 and miniaturizing it as much as possible.

[0054] like Figure 6 As shown, a heat sink 8 is also provided at the bottom of the chassis 1. The heat sink 8 is used to cool down the compressor and other heat dissipation mechanisms so that they can work continuously and stably.

[0055] like Figures 1 to 3 As shown, the chassis 1 is also provided with several ventilation and heat dissipation holes 11, a water collection platform 12, and a display panel 13. The water collection platform 12 is located below the switch control valve 6, and the display panel 13 is located above the switch control valve 6. A feeding port is also provided on the top of the chassis 1. The feeding port opens to the top of the mixing tank 21, and a top cover 23 is also provided at the feeding port.

[0056] The ice cream machine with the novel stirring structure in this embodiment improves the stirring components by adopting a combination structure of stirring blade, scraper and disc, which not only improves stirring efficiency, but also stirs the bottom ingredients more thoroughly, thus ensuring a better taste of the prepared ice cream.

[0057] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
