Description

Technical Field

[0001] The utility model relates to the technical field of ice liner refrigerators, in particular to an ice liner refrigerator. Background Art

[0002] An ice-lined refrigerator is a refrigerator that uses an ice lining plate to store cold. It is mostly composed of a cabinet, an insulation layer, an ice lining, an inner tank, and a compressor device installed at the bottom of the cabinet. Currently, the ice lining of an ice-lined refrigerator is filled with phase change materials, and the layout of the ice lining mainly includes the following three forms.

[0003] First, it is arranged on the inner walls of the box body, surrounding the storage space to achieve thermal insulation, but the distance between the storage space and the ice lining is inconsistent, and the temperature fluctuation range inside the box is large; second, it is arranged on one side of the box body, such as the side, top or bottom, but its single-sided setting also leads to poor thermal insulation ability and a large temperature fluctuation range, and is only limited to refrigerators with a small effective volume. If the volume is too large, it will cause serious attenuation during cold transfer; third, the ice lining structure filled with phase change material is detachably installed in the box, but the disadvantage is that the phase change material used needs to be taken out and frozen separately as a cold source, which is cumbersome for users to operate.

[0004] In summary, current ice-lined refrigerators all store cold through phase change materials filled in the ice lining layer and achieve refrigeration through cold transfer. However, the above three forms have disadvantages such as large temperature fluctuations and inconvenience in use. Therefore, we consider how to make the temperature inside the box more stable and balanced. In view of this, we propose an ice-lined refrigerator. Utility Model Content

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model describes the above technical solution in detail through the following embodiments:

[0028] An ice-lined refrigerator comprises a refrigerator body 1 equipped with a door 2, and an evaporator 7 for refrigeration, and further comprises:

[0029] The cold source part is arranged at the center of the refrigerator body 1 and is used as a cold source to provide cold energy, and includes an inner cover 6, an ice lining layer 5, a deformation buffer layer 4 and a temperature control outer shell 3 which are arranged in sequence from the inside to the outside;

[0030] A freezing storage cavity 61 for providing a freezing space is provided on the inner cover 6 , and a refrigerating storage cavity is provided between the refrigerator body 1 and the temperature-controlled outer shell 3 .

[0031] See also Figure 6 In the structure shown, in this embodiment, an installation gap is provided between the ice lining 5 and the inner cover 6, the evaporator 7 is arranged in the installation gap, and the inner cover 6 is provided with evenly distributed cold transfer holes 601; it should be explained that the temperature of the evaporator 7 is very low when working, and its main function is freezing, and the temperature can reach below zero. By freezing the ice lining 5 at low temperature, the phase change material filled in the ice lining 5 can be used as a cold source, and a continuous cold transfer capability is obtained when the evaporator 7 is shut down, and a continuous refrigerated environment can be obtained through the ice lining 5, which is a heat preservation method.

[0032] See also Figure 5 and Figure 6 In the structure shown, an insulating filling cavity 301 for filling insulating cotton material is provided inside the temperature-controlled shell 3, and evenly distributed cold transfer blocks 8 are inserted on the temperature-controlled shell 3. The ice lining 5 inside can be insulated through the temperature-controlled shell 3, and part of the cold energy can be conducted through the cold transfer blocks 8. The main purpose is to transfer cold energy to the refrigerated storage cavity provided between the refrigerator body 1 and the temperature-controlled shell 3 through the cold transfer blocks 8. However, the cold energy is attenuated during the transfer process, so it is inconsistent with the freezing temperature in the freezing storage cavity 61. Therefore, the device can obtain the freezing area and the refrigerated area based on the cold source part, thereby improving the functionality of the device.

[0033] See also Figure 5 and Figure 6 As shown in the structure, the deformation buffer layer 4 of this embodiment adopts a rubber strip structure that is continuously connected from top to bottom, which can obtain deformation ability after the inner ice lining layer 5 is frozen and expanded to avoid damage to this part; and a through-hole structure is provided on the rubber strip structure to obtain a better cold transfer effect.

[0034] In this embodiment, the distance between the ice lining layer 5 and the corresponding side of the inner wall of the refrigerator body 1 is consistent, and Figure 1 and Figure 2 As shown in the structure, the refrigerator body 1 adopts a semicircular structure at both ends, which is convenient for maintaining a consistent distance between any box wall and the cold source, and then helps to keep the temperature inside the box more stable and balanced.

[0035] The working principle of the ice-lined refrigerator of this embodiment is as follows: the evaporator 7 works to cool down and freeze the ice lining 5, and the ice lining 5 changes in volume and then deforms and buffers the buffer layer 4. At this time, the temperature in the freezing storage chamber 61 is below zero for freezing. The cold energy will decay greatly after passing through the deformed buffer layer 4 and the temperature control shell 3 filled with heat insulation cotton. The cold energy is transmitted as follows: Figure 5 and Figure 6 The cold transfer block 8 of the structure shown transfers cold to the cold storage chamber to obtain the refrigerated temperature. In this embodiment, the cold transfer block 8 is made of aluminum profile.

[0036] 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 in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0037] 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 implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
