Description

Technical Field

[0001] This utility model relates to the field of ice maker technology, specifically to an evaporator for an ice maker. Background Technology

[0002] The evaporator is the core component of an ice maker. One type of ice maker, called a slush machine, has a cylindrical evaporator, known as an evaporator drum. For example, a technical solution disclosed in patent application CN1103545C describes a slush machine where ice forms on the inner and outer circumferential surfaces of the evaporator drum. A drive motor rotates a shaft connected to a scraper, which contacts the inner and outer circumferential surfaces of the evaporator drum. As the scraper rotates and contacts these surfaces, it scrapes off the ice. The scraper continues to remove ice, which mixes with the beverage source in the beverage container to produce a slush-like beverage.

[0003] For a long time, the evaporators of slush machines have been designed in a cylindrical shape based on the above principle. However, the applicant proposes a new type of evaporator for ice makers, which provides another approach. This new evaporator is not cylindrical in design and differs from the working principle of existing technologies, and can be applied to slush machines. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an evaporator for an ice maker, which is non-cylindrical in design and has a working principle that is different from the prior art, and can be applied to slush machines.

[0005] The technical solution of this utility model is: an evaporator for an ice maker, including a trough-shaped body for containing the liquid to be cooled, the trough-shaped body including an arc-shaped bottom and side plates located on both sides of the arc-shaped bottom, and a cooling surface is provided at least at the arc-shaped bottom for freezing the liquid to be cooled.

[0006] With the above structure, this utility model has the following advantages:

[0007] This disclosure, through an improved, non-cylindrical design, operates on the principle that the trough-shaped main body contains the liquid to be cooled, and the cooling surface is used to freeze the liquid. In a slush machine, since the cooling surface is located at least at the curved bottom, the scraper can cooperate with the curved bottom to continuously scrape away the ice formed on the cooling surface. This scraped ice rises, thus squeezing the liquid towards the cooling surface, creating active convection. Therefore, the scraped ice is less likely to accumulate on the cooling surface and affect its freezing process. With continuous operation, the cooled liquid gradually transforms into a slush-like consistency. Of course, the evaporator of this disclosure can also be used in other ice makers, such as ice cream machines, if needed.

[0008] In summary, the present disclosure features a non-cylindrical design and a working principle that differs from the prior art, making it applicable to slush machines.

[0009] Preferably, cooling pipes are provided on the back side of the cooling surface.

[0010] As a preferred option, the trough-shaped main body is equipped with an insulation layer.

[0011] Preferably, the main body of the groove is configured as a U-shaped groove. Attached image description:

[0015] To better understand this application, various aspects of this application will be described in more detail below with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely illustrative of exemplary embodiments of this application and are not intended to limit the scope of this application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0016] In the accompanying drawings, the thickness, size, and shape of the objects have been slightly exaggerated for illustrative purposes. The drawings are for illustrative purposes only and are not drawn to scale.

[0017] It should also be understood that the terms “comprising,” “including,” “having,” “containing,” “comprise,” and “containing”, when used in this specification, indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0018] like Figures 1 to 2 As shown, this disclosure proposes an evaporator for an ice maker, including a trough-shaped body for containing a liquid to be cooled. The trough-shaped body includes an arc-shaped bottom 1 and side plates 2 located on both sides of the arc-shaped bottom 1. At least a cooling surface 3 is provided on the arc-shaped bottom 1 for freezing the liquid to be cooled.

[0019] This disclosure provides a cooling surface 3 at the bottom of the trough-shaped main body, which forms the working principle of ice floating, thus facilitating ice making and ice scraping.

[0020] The main body of the trough is designed as a U-shaped trough.

[0021] A refrigeration pipe 4 is installed on the back side of the refrigeration surface 3. In this example, the refrigeration pipe 4 is arranged in a serpentine coil shape on the back side of the arc-shaped bottom 1. The refrigeration pipe 4 is connected to an inlet pipe 5 for introducing refrigerant and an outlet pipe 6 for discharging refrigerant.

[0022] The trough-shaped body can also be further equipped with an insulation layer, for example in... Figure 1 , 2 The outer surface of the trough-shaped main body shown is covered with an additional insulation layer through a sandwich foaming process.

[0023] When understanding this utility model, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that is understood, so I will not elaborate further here.

[0024] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
