[0034] 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.

[0035] First embodiment:

[0036] See Figures 1-3 An evaporator for an ice cream machine includes a container 1 and a heat exchanger 2. The container 1 is provided with a cavity 3 for placing ice cream raw materials to form ice cream. The container 1 is installed on the heat exchanger 2, and the container 1 and the heat exchanger 2 are arranged in an upper and lower layer. A flow path 4 for refrigerant to flow is provided between the container 1 and the heat exchanger 2. The refrigerant flows through the flow path 4 and directly cools the container 1.

[0037] In this embodiment, the ice cream machine evaporator is arranged with container 1 and heat exchanger 2 arranged in upper and lower layers, with a flow path 4 for refrigerant flow between them. This structural design brings many advantages to the evaporator. The flow path 4 is arranged along the length of the ice cream machine evaporator and consists of several independent flow channels arranged at intervals and interconnected, which allows the refrigerant to flow in an orderly manner in the flow path 4, ensuring full contact between the refrigerant and container 1, thereby improving the efficiency of heat exchange. Container 1 is installed in the receiving cavity 5 of heat exchanger 2, and the flow path 4 is formed between the recess 6 and the outer bottom of container 1. This design increases the contact area between container 1 and heat exchanger 2, further enhancing heat conduction.

[0038] The flow path 4 between the container 1 and the heat exchanger 2 is arranged along the length of the ice cream machine evaporator.

[0039] The flow path 4 includes several independent flow channels that are spaced apart and interconnected.

[0040] The heat exchanger 2 is provided with a receiving cavity 5 for accommodating the container 1. The receiving cavity 5 of the heat exchanger 2 is provided with a recess 6. The top of the recess 6 is provided with an opening communicating with the receiving cavity 5. A flow path 4 is formed between the recess 6 and the outer side of the bottom of the container 1.

[0041] The recess 6 is provided in several parts, and the several recesses 6 are arranged at intervals along the length direction of the ice cream machine evaporator and are interconnected.

[0042] Both the container 1 and the heat exchanger 2 are provided with an extension edge 8 on their tops. The extension edges 8 between the container 1 and the heat exchanger 2 are fixedly connected by welding, so that the container 1 and the heat exchanger 2 are fixedly connected.

[0043] The bottom of the container 1 and the heat exchanger 2 are fixedly connected by welding.

[0044] In this embodiment, the extended edge 8 can be used to fix the evaporator to the top of the inner cavity of the ice maker, which makes it convenient for the user to place ice cream ingredients on the top of the machine. In addition, when the user does not need to disassemble and clean the container 1, the user can directly wipe and clean the container 1 on the machine.

[0045] The container 1 and the heat exchanger 2 are fixedly connected and cannot be separated, or the container 1 and the heat exchanger 2 are detachably connected.

[0046] In this embodiment, the container 1 and the heat exchanger 2 are fixedly connected by welding and cannot be separated.

[0047] Both sides of the heat exchanger 2 are provided with connecting pipes 9 for connecting the flow path 4.

[0048] One of the connecting pipes 9 is connected to the evaporator, and the other connecting pipe 9 is connected to the compressor.

[0049] The recess 6 protrudes outward and is disposed on the outside of the heat exchanger 2, forming a first reinforcing rib for increasing the mechanical strength of the heat exchanger 2.

[0050] In this embodiment, the inner bottom wall of the heat exchanger 2 is provided with a hollowed-out groove to reduce the weight of the heat exchanger 2, and a hollowed-out groove is provided between two adjacent recesses 6. Since there is a communication gap between the inner side of the container 1 and the inner circumference of the heat exchanger 2, and the bottom of the container 1 and the heat exchanger 2 are fixedly connected by welding, it can be understood that the gap between the hollowed-out grooves of the container 1 and the heat exchanger 2 is sealed by the weld to prevent refrigerant leakage, so that the refrigerant flows sequentially along each recess 6.

[0051] The recess 6 protrudes outward and forms the first reinforcing rib on the outer side of the heat exchanger 2. This not only improves the mechanical strength of the heat exchanger 2, making it less prone to deformation and damage during long-term use and ensuring the stability of the evaporator structure, but also indirectly optimizes the flow path of the refrigerant in the flow path 4, improving the cooling effect. Meanwhile, the container 1 and the heat exchanger 2 are fixedly connected by welding, and their bottoms are also sealed by welding, effectively preventing refrigerant leakage and ensuring the safety and reliability of the evaporator operation. Furthermore, the hollowed-out groove on the inner bottom wall of the heat exchanger 2 reduces its weight and helps save raw materials, lowering production costs, giving this evaporator significant advantages in both performance and economy.

[0052] Second embodiment:

[0053] See Figures 4-5 The ice cream machine evaporator differs from the first embodiment in that: a protrusion 7 is provided on the bottom wall of the cavity 3 of the container 1, and a flow path 4 is formed between the protrusion 7 and the bottom wall of the heat exchanger 2.

[0054] The protrusion 7 is provided on the inner bottom wall of the container 1 and forms a second reinforcing rib to increase the mechanical strength of the container 1.

[0055] All other parts not described herein are the same as in the first embodiment and will not be described in detail here.

[0056] Compared to the first embodiment, the evaporator of the ice cream machine in the second embodiment has a protrusion 7 on the bottom wall of the cavity 3 of the container 1. A flow path 4 is formed between the protrusion 7 and the bottom wall of the heat exchanger 2. This unique structural improvement brings a series of new beneficial effects. The protrusion 7 is set upward on the bottom wall of the container 1 and forms a second reinforcing rib, which greatly enhances the mechanical strength of the container 1. This allows the container 1 to maintain good structural integrity when bearing the weight of the ice cream raw materials and the pressure changes during the refrigeration process, reducing the risk of deformation or damage caused by external forces and extending the service life of the container 1.

[0057] From the perspective of refrigeration principle, the presence of protrusion 7 changes the shape and spatial layout of flow path 4, increasing the contact path and contact area between the refrigerant and container 1. When the refrigerant flows through flow path 4, it can more fully absorb the heat from the ice cream ingredients in container 1, accelerate the cooling and solidification speed of the ice cream ingredients, and improve the refrigeration efficiency of the evaporator.

[0058] In this embodiment, the container 1 is provided with two spaced-apart elongated protrusions 7.

[0059] Third embodiment:

[0060] See Figures 6-7 The ice cream machine evaporator differs from the first embodiment in that: several recesses 6 are connected end to end in sequence to form a continuous flow path 4.

[0061] The flow path 4 is a single, continuously extending flow channel;

[0062] Alternatively, flow path 4 can be a continuously spiral-shaped flow channel;

[0063] Alternatively, flow path 4 can be a wavy, meandering flow channel;

[0064] Alternatively, flow path 4 can be formed by connecting several straight channels end to end to create a continuous serpentine flow path.

[0065] Alternatively, flow path 4 can be a wavy, meandering channel.

[0066] All other parts not described herein are the same as in the first embodiment and will not be described in detail here.

[0067] In the third embodiment, several recesses 6 of the ice cream machine evaporator are connected end to end to form a continuous flow path 4. The flow path 4 has various flexible forms, such as a continuously extending single flow channel, a continuously spirally distributed flow channel, or a wavy, meandering flow channel. This continuous flow path 4 design greatly improves the flow of refrigerant within the evaporator. Compared to the spaced independent flow channels in the first embodiment, the continuous flow path 4 significantly reduces the resistance to refrigerant flow, allowing the refrigerant to circulate more smoothly within the flow path 4. This avoids flow obstruction and energy loss caused by intermittent flow channels, thereby effectively improving the utilization rate of the refrigerant.

[0068] The diverse flow path 4 configurations allow for a richer and more rational contact path between the refrigerant and container 1. Whether the flow path is spiral, wavy, or serpentine, it ensures more thorough and uniform heat exchange between the refrigerant and container 1 during flow. This effectively prevents uneven cooling in certain areas within container 1, guaranteeing that the ice cream ingredients inside container 1 can cool and solidify simultaneously.

[0069] Fourth embodiment:

[0070] See Figures 8-10The evaporator for an ice cream machine differs from the first embodiment in that: the top of the recess 6 is a closed structure, a flow path 4 is formed inside the recess 6, and the flow path 4 and the receiving cavity 5 are independently spaced vertically and are not interconnected. Several recesses 6 are provided.

[0071] Several recesses 6 are connected end to end to form a continuous flow path 4.

[0072] The flow path 4 is a single, continuously extending flow channel;

[0073] Alternatively, flow path 4 can be a continuously spiral-shaped flow channel;

[0074] Alternatively, flow path 4 can be a wavy, meandering flow channel;

[0075] Alternatively, flow path 4 can be formed by connecting several straight channels end to end to create a continuous serpentine flow path.

[0076] Alternatively, flow path 4 can be a wavy, meandering channel.

[0077] All other parts not described herein are the same as in the first embodiment and will not be described in detail here.

[0078] In the fourth embodiment of the ice cream machine evaporator, the top of the recess 6 is a closed structure (the opening at the top of the recess 6 can be sealed by a welding surface). A flow path 4 is formed inside the recess 6, and the flow path 4 and the receiving cavity 5 are arranged independently at intervals and are not interconnected. At the same time, several recesses 6 are connected end to end to form a continuous flow path 4. This unique structural design firstly provides an independent, closed and stable flow space for the refrigerant.

[0079] The refrigerant flows stably within the closed flow path 4, efficiently transferring heat with the container 1. Several recesses 6 are sequentially connected end-to-end to form a continuous flow path 4, continuing the advantages of the continuous flow path 4 in the third embodiment. This reduces refrigerant flow resistance, improves refrigerant utilization, and further ensures the high efficiency and stability of the evaporator. The closed structure of the recesses 6 also enhances the overall structural strength of the evaporator, enabling it to better maintain its shape and performance under pressure and external forces, extending the evaporator's service life and providing a reliable guarantee for the stable operation of the household ice cream maker.

[0080] 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.
