[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] See Figures 1-7 An ice cream machine includes a body 1 and an evaporator 2 for ice cream forming. The body 1 is provided with an insulation layer to prevent heat loss from the evaporator 2 during the ice cream forming process. The evaporator 2 is provided with an ice cream cavity 6 for ice cream forming. The body 1 is also provided with a visualization unit 4 for observing the ice cream forming process. The visualization unit 4 is located above the ice cream cavity 6. The projection of the visualization unit 4 and the ice cream cavity 6 coincides in the top view or bottom view direction.

[0031] An insulation layer is installed inside the main body 1 to effectively prevent heat loss from the evaporator 2 during the ice cream forming process. Heat loss reduces the cooling efficiency of the evaporator 2 and increases energy consumption. The insulation layer reduces cold loss, maintains a stable low-temperature environment around the evaporator 2, and ensures proper ice cream forming. Simultaneously, the evaporator 2 has an ice cream cavity 6 for ice cream forming, fulfilling the core functional requirements of the ice maker. More importantly, the visualization unit 4 on the main body 1 is located above the ice cream cavity 6, and the projections of the visualization unit 4 and the ice cream cavity 6 coincide in the top or bottom view. This allows users to directly observe the forming state and solidification degree of the ice cream inside the ice cream cavity 6 without opening the ice maker lid during ice cream making. Compared to traditional fully enclosed ice makers, this design avoids cold loss and additional energy consumption caused by opening the lid for observation, eliminates the adverse effects of temperature fluctuations on ice cream forming quality, significantly improves the ease of use of the ice maker and the ice cream making effect, and features a simple, lightweight, and convenient structural design.

[0032] The evaporator 2 is installed laterally inside the body 1 along the length of the body 1; the insulation layer is formed by filling with foam material.

[0033] The evaporator 2 is installed laterally within the body 1 along its length. This installation method makes more efficient use of the internal space of the body 1, resulting in a more compact and orderly internal structure layout for the ice maker. Meanwhile, the insulation layer is formed by filling with foam material, which has excellent thermal insulation properties, further enhancing the insulation effect. The foam material is lightweight, contributing to the overall compact and convenient design of the machine.

[0034] The evaporator 2 is equipped with a heat exchange chamber 7 for refrigerant flow and for mounting the ice cream cavity 6. The ice cream cavity 6 is detachably mounted on the heat exchange chamber 7. This detachable mounting method allows for quick cleaning, maintenance, or replacement of the ice cream cavity 6, ensuring the hygiene and normal operation of the ice maker. Furthermore, the heat exchange chamber 7 allows the refrigerant to flow within it, efficiently exchanging heat with the ice cream cavity 6, thereby achieving rapid cooling of the material inside the ice cream cavity 6, accelerating the ice cream forming speed, and improving the working efficiency of the ice maker.

[0035] Alternatively, the ice cream cavity 6 and the heat exchange cavity 7 are fixedly connected and cannot be separated, and a gap for refrigerant flow is formed between the ice cream cavity 6 and the heat exchange cavity 7.

[0036] In this embodiment, the ice cream cavity 6 is provided with a positioning flange positioned at the opening of the heat exchange cavity 7. The ice cream cavity 6 is provided with a groove for placing a wooden or plastic rod.

[0037] The machine body 1 is equipped with a condenser 8 and a compressor 9. The output end of the compressor 9 is connected to the input end of the condenser 8, the output end of the condenser 8 is connected to the input end of the heat exchange chamber 7 of the evaporator 2, and the output end of the heat exchange chamber 7 is connected to the input end of the compressor 9, so as to form a closed-loop pipeline for refrigerant circulation.

[0038] Compressor 9 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then sent to condenser 8. Condenser 8 cools and liquefies the high-temperature, high-pressure gaseous refrigerant, releasing heat. The liquefied refrigerant then flows into the heat exchange chamber 7 of evaporator 2, where it absorbs heat from the ice cream cavity 6 and its internal materials, achieving a cooling effect and allowing the ice cream to solidify. Afterward, the refrigerant returns to the compressor 9 as a gas, and this cycle repeats continuously. This closed-loop piping system continuously and stably provides cooling to evaporator 2, ensuring the continuity and stability of the ice maker's cooling process, thereby ensuring that the ice cream can be successfully solidified under suitable temperature conditions, improving the overall performance and reliability of the ice maker.

[0039] The machine body 1 has a mounting cavity 3 for installing the evaporator 2. The evaporator 2 is installed on top of the mounting cavity 3 and suspended inside the machine body 1. Below the evaporator 2, the mounting cavity 3 houses the condenser 8 and the compressor 9. This layout fully considers the functions and operating characteristics of the various components inside the ice maker. The evaporator 2's suspended position at the top of the mounting cavity 3 facilitates air circulation around it, improving its heat exchange efficiency and allowing it to dissipate heat more quickly and effectively, thus ensuring the material in the ice cream cavity 6 cools and solidifies rapidly. Simultaneously, placing the condenser 8 and compressor 9 below the evaporator 2 makes efficient use of the internal space of the machine body 1, resulting in a more compact ice maker structure. Furthermore, this layout prevents the heat generated by the condenser 8 and compressor 9 from interfering with the cooling effect of the evaporator 2, ensuring its cooling performance and improving the ice maker's operational stability and cooling efficiency.

[0040] In this embodiment, a cooling fan is provided on one side of the condenser 8, and ventilation holes are provided on the side of the body 1. The outer side of the evaporator 2 is provided with a flange positioned on the edge of the opening groove of the mounting cavity 3.

[0041] The body 1 includes a base 10, on which a first bracket 11 for fixing the condenser 8 is provided. The compressor 9 is fixedly installed on the base 10. The base 10 is provided with a second bracket 12 away from the first bracket 11. The bottom of the evaporator 2 is supported by the first bracket 11 and the second bracket 12. The evaporator 2 is provided with a connecting block 13 that is fixedly connected to the first bracket 11 or the second bracket 12.

[0042] In this embodiment, the base 10 is provided with a limiting and fixing block for fixing the first bracket 11 and the second bracket 12. The first bracket 11 and the second bracket 12 are fixedly connected to the limiting and fixing block by screws.

[0043] The top of the first bracket 11 or the second bracket 12 is fixedly connected to the connecting block 13 with screws. The first bracket 11 and the second bracket 12 provide reliable support for the evaporator 2, ensuring that the evaporator 2 remains stable during the operation of the ice maker and will not shift due to vibration or other factors, thereby ensuring the stability of the connecting pipes between the evaporator 2 and other components. The condenser 8 is fixedly mounted on the base 10 via the first bracket 11, and the compressor 9 is also directly fixed to the base 10, making the installation of the internal components of the ice maker more secure and the overall structure more stable.

[0044] The body 1 is provided with a cover 5 that opens and closes on the body 1, and a visualization unit 4 is disposed on the cover 5.

[0045] The visualization unit 4 and the cover 5 are integrally formed, and both the visualization unit 4 and the cover 5 are made of transparent material; or, the visualization unit 4 is a transparent window installed on the cover 5.

[0046] When the visualization unit 4 and the cover 5 are integrally molded, and both are made of transparent material, this design reduces the connection gaps between components, improves the overall sealing and structural strength of the cover 5, and ensures good visibility, allowing users to clearly and comprehensively observe the ice cream forming process inside the ice cream cavity 6. If the visualization unit 4 is a transparent window installed on the cover 5, this method increases design flexibility, meeting user observation needs while facilitating individual replacement or repair of the transparent window, reducing maintenance costs. Whether integrally molded or with a transparent window, users can observe the ice cream forming process in real time, avoiding the need to open the cover to observe the process, thus improving the performance and user experience of the ice maker.

[0047] The lid 5 protects the evaporator 2 and ice cream cavity 6 inside the machine body 1 when the ice maker is not in use, preventing dust and debris from entering and affecting the normal operation of the ice maker and the hygienic quality of the ice cream. The visualization unit 4 is located on the lid 5, allowing users to easily observe the ice cream forming process inside the ice cream cavity 6 even when the lid 5 is closed. This design not only meets the user's need to observe the ice cream forming process but also ensures the airtightness of the ice maker's interior, reducing cold loss and energy consumption. Furthermore, the opening and closing design of the lid 5 facilitates user operation of the ice maker's interior when needed, such as adding materials or cleaning, improving the convenience and practicality of the ice maker.

[0048] In this embodiment, the transparent glass is prone to condensation due to the temperature difference between the inside and outside. The cover 5 is equipped with a heating wire, which keeps the glass surface temperature above the dew point temperature through constant temperature heating, thus preventing water vapor condensation and ensuring that the visualization unit 4 is always clear. Users can observe the ice cream forming status in real time without frequent wiping.

[0049] A fastening assembly 14 is provided between the body 1 or evaporator 2 and the cover 5 so that the cover 5 is tightly closed on the body 1 when the cover is closed.

[0050] The fastening assembly 14 includes a fixed buckle 15 disposed on the body 1 or the evaporator 2, and a movable buckle 16 flexibly disposed on the cover 5;

[0051] When the cover 5 is closed, the movable buckle 16 is engaged with the fixed buckle 15 under the action of elasticity. When the movable buckle 16 is disengaged from the fixed buckle 15, the cover 5 can be opened onto the body 1.

[0052] The cover 5 includes a frame component hinged to the body 1 and a bottom cover fixedly connected to the frame component. The frame component is provided with an opening slot for installing the visualization unit 4. The visualization unit 4 is installed between the frame component and the bottom cover.

[0053] The frame component is provided with a spring-loaded rotating pressing panel 21. The inner side of the pressing panel 21 is provided with a buckle that engages with the evaporator 2. The buckle moves with the pressing panel 21 to form a movable buckle 16.

[0054] A gap 17 is provided between the inner side of the cover 5 and the pressing panel 21 for operating the pressing panel 21 to rotate.

[0055] With the lid 5 closed, the movable latch 16 engages with the fixed latch 15 under elastic action. This engagement method ensures that the lid 5 is tightly sealed to the body 1, guaranteeing the airtightness of the ice maker's interior. Good sealing effectively prevents cold air loss, maintains a low-temperature environment inside the ice maker, improves its cooling efficiency, and reduces energy consumption. Simultaneously, when it is necessary to open the lid 5, the movable latch 16 disengages from the fixed latch 15, allowing the lid 5 to be opened easily. This simple and convenient operation facilitates user access to and maintenance of the ice maker's interior.

[0056] In this embodiment, the pressing panel 21 is rotatably connected to the frame member via a rotating shaft. A torsion spring is provided on the rotating shaft so that the pressing panel 21 is elastically rotated on the frame member.

[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
