Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a flooded evaporator. Background Art

[0002] Popsicles are one of the most familiar cold foods. They are usually low in cost and are made by mixing and freezing water, juice, sugar, milk, etc. They are especially thirst-quenching and heat-relieving in summer. With the improvement of living standards and the enhancement of food safety awareness, popsicles purchased directly on the market contain a lot of additives. Therefore, people prefer to make popsicles, ice cream and other snacks at home.

[0003] A popsicle machine is an appliance that can be used to make popsicles at home. The evaporator is one of the key components. It absorbs heat to lower the temperature of the surrounding environment, thereby achieving a cooling effect. However, traditional popsicle machines generally place the popsicle molds in a refrigerant first, then the compressor cools the refrigerant through the evaporator, and then cools the popsicle molds through the refrigerant. This results in a low heat transfer coefficient, slow ice formation, and high energy consumption. Utility Model Content

[0018] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0019] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0020] The following will be combined with specific embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0021] See also Figures 1 to 5 As shown, the structure of the utility model is as follows: a full-liquid evaporator, comprising a molding cavity 1 with an opening at one end, a cover plate 101 being provided on the molding cavity 1; an evaporation shell 2, the evaporation shell 2 being sleeved on the outside of the molding cavity 1, the evaporation shell 2 being sleeved on the outside of the molding cavity 1, and being sealed and connected with the cover plate 101 as a whole, and forming a hollow evaporation cavity 3 between the evaporation shell 2 and the outer wall of the molding cavity 1; a liquid inlet 5 being provided at the bottom of the evaporation shell 2, and a liquid outlet 6 being provided at the side of the evaporation shell 2. Specifically, the liquid inlet 5 is connected to the condenser in the refrigeration system through a capillary tube, and the liquid outlet 6 is connected to the compressor in the refrigeration system. After the refrigerant is compressed by the compressor, it is cooled by the condenser, and then enters the evaporation cavity 3 after throttling and reducing the pressure by the capillary tube. Then, the refrigerant expands and gasifies in the evaporation cavity 3, and the evaporation cavity 3 wraps the entire outer side of the molding cavity 1, so that the contact surface between the refrigerant in the evaporation cavity 3 and the outer side of the molding cavity 1 is large, the heat exchange efficiency is higher, and the heat in the molding cavity 1 can be quickly absorbed.

[0022] like Figure 3 As shown, the cross section of the molding cavity 1 is an inverted trapezoidal structure. Specifically, the inverted trapezoidal structure, which is wide at the top and narrow at the bottom, is conducive to taking out the frozen popsicles from the molding cavity 1.

[0023] like Figure 2 , Figure 3 As shown, the inner side of the molding cavity 1 is provided with an arc chamfer. Specifically, the arc chamfer is for facilitating the cleaning of the molding cavity 1 and preventing the occurrence of sanitary dead corners. On the other hand, it is conducive to ensuring the complete removal of the popsicle.

[0024] like Figures 1 to 3 As shown, at least two forming cavities 1 are provided. Specifically, multiple popsicles can be formed at one time, which is beneficial to improving the efficiency of popsicle forming.

[0025] like Figure 2 , Figure 5 As shown, the outer side of the evaporation shell 2 is covered with a shell 4. Specifically, the shell 4 is used to protect the evaporation shell 2 to prevent the evaporation shell 2 from being damaged.

[0026] like Figure 2As shown, an insulation cavity 7 is formed between the outer shell 4 and the evaporation shell 2, and the insulation cavity 7 is filled with foaming material. Specifically, the foaming material is polyurethane, which is used to prevent external heat from entering the evaporation cavity 3 and the molding cavity 1, and can effectively protect the temperature in the evaporation cavity 3 and the molding cavity 1.

[0027] During specific use, the liquid inlet 5 is connected to the condenser in the refrigeration system through a capillary tube, and the liquid outlet 6 is connected to the compressor in the refrigeration system. After being compressed by the compressor, the refrigerant is cooled down through the condenser, and then enters the evaporation chamber 3 after throttling and reducing the pressure through the capillary tube. Then the refrigerant expands and vaporizes in the evaporation chamber 3, and the evaporation chamber 3 wraps the entire outside of the molding chamber 1, so that the contact area between the refrigerant in the evaporation chamber 3 and the outside of the molding chamber 1 is large, and the heat exchange efficiency is higher. The heat in the molding chamber 1 can be quickly absorbed, and the external heat is prevented from entering the evaporation chamber 3 and the molding chamber 1 through the insulation chamber 7, which can effectively protect the temperature in the evaporation chamber 3 and the molding chamber 1 and improve the refrigeration efficiency.

[0028] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
