Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a horizontal freezer. Background Technology

[0002] In horizontal air-cooled freezers, a sealing strip is installed between the door and the cabinet body. When the door is closed on the cabinet body, the sealing strip seals the gap between the door and the cabinet body to prevent cold air from leaking out and reduce cold loss. However, the sealing strip tends to harden over time in low-temperature environments. A hardened sealing strip reduces its sealing effectiveness, increasing the freezer's cold air consumption. Furthermore, the opening between the door and the cabinet body is frequently exposed to outside air, making it prone to frost and condensation. Frost and condensation can affect the opening and closing of the door, impacting the freezer's cooling performance. Summary of the Invention

[0003] In order to solve the problems of easy hardening of sealing strips and easy frost and condensation at sealing strips and openings in the existing technology, the purpose of this utility model is to provide a refrigerator that maintains the toughness of sealing strips and is not prone to frost and condensation.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a freezer, comprising:

[0005] The cabinet has an internal cavity, and the top of the cabinet has an opening that connects to the cavity.

[0006] Cabinet doors, rotatably mounted on the top of the cabinet body to open and close the opening; and

[0007] A door sealing assembly is installed on the inside of the cabinet door. The door sealing assembly includes a sealing strip and a heating element. When the cabinet door is closed, the sealing strip seals between the cabinet door and the cabinet body and surrounds the outside of the opening. The heating element is arranged close to the sealing strip and along the extension direction of the sealing strip.

[0008] In the above technical solution, it is further preferred that the sealing strip includes a fixing part embedded in the cabinet door and a sealing part extending out of the inner surface of the cabinet door, wherein the thickness of the sealing part is less when the cabinet door is closed and the opening is open.

[0009] In the above technical solution, a further preferred embodiment is that a groove is formed on the inner surface of the cabinet door, and the fixing part is embedded in the groove.

[0010] In the above technical solution, it is further preferred that the heating element is arranged in the groove and located between the fixing part and the wall of the groove.

[0011] In the above technical solution, it is further preferred that the heating element is a carbon fiber heating wire.

[0012] In the above technical solution, it is further preferred that the sealing strip is a rubber sealing ring.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention installs a heating wire at the sealing strip between the cabinet door and the cabinet body. The heating wire heats the sealing strip, which on the one hand keeps the sealing strip flexible, thus ensuring the sealing effect between the cabinet door and the cabinet body, and on the other hand solves the problem of frost and condensation easily forming on the sealing strip and the opening.

[0017] The components are: 10. Cabinet body; 1. Receiving cavity; 3. Opening; 20. Cabinet door; 6. Groove; 30. Door seal assembly; 4. Sealing strip; 41. Fixing part; 42. Sealing part; 5. Heating element. Detailed Implementation

[0018] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, construction, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0019] like Figure 1 As shown, this utility model embodiment provides a freezer, which belongs to the horizontal freezer category, including: a cabinet body 10, a cabinet door 20 rotatably installed on the top of the cabinet body 10, a door seal assembly 30 installed on the inner side of the cabinet door 20, and a refrigeration system (not shown in the figure) that provides cooling capacity.

[0020] The cabinet 10 has an interior cavity 1 for storing items at low temperatures, and a refrigeration system is arranged on one side of the cavity 1 to provide cooling to the cavity 1. The top of the cabinet 10 has an opening 3 that communicates with the cavity 1, allowing the user to take items into and out of the cavity 1 through the opening 3. The cabinet door 20 can rotate back and forth at the top of the cabinet 10 to open and close the opening 3.

[0021] like Figure 1 , 2 As shown, when the cabinet door 20 closes the opening 3, the door sealing assembly 30 seals between the cabinet door 20 and the cabinet body 10 to prevent cold air leakage inside the cabinet body 10. The door sealing assembly 30 includes a sealing strip 4 and a heating element 5. When the cabinet door 20 closes the opening 3, the sealing strip 4 seals between the cabinet door 20 and the cabinet body 10 and surrounds the opening 3 to enhance the sealing effect between the cabinet door 20 and the cabinet body 10 at the opening 3. The sealing strip 4 is a rubber sealing ring. When the cabinet door 20 closes the opening 3, the sealing strip 4 is elastically compressed between the cabinet door 20 and the cabinet body 10 to enhance the sealing of the container cavity 1. The heating element 5 is arranged close to the sealing strip 4 and along the extension direction of the sealing strip 4. The heating element 5 is used to heat the sealing strip 4 around the opening 3. On the one hand, it prevents the sealing strip 4 from hardening in a low-temperature environment for a long time, which would affect the sealing effect. On the other hand, it heats the opening 3 to prevent condensation and frost from forming.

[0022] The sealing strip 4 includes a fixing part 41 embedded in the cabinet door 20 and a sealing part 42 extending out of the inner surface of the cabinet door 20. The thickness of the sealing part 42 is less when the cabinet door 20 is closed and the opening 3 is open. The elastic deformation of the sealing part 42 can better seal the gap between the cabinet door 20 and the cabinet body 10.

[0023] A groove 6 is formed on the inner surface of the cabinet door 20. The fixing part 41 is embedded in the groove 6, so that the sealing strip 4 can be stably installed on the cabinet door 20. The heating element 5 is arranged in the groove 6 and is located between the fixing part 41 and the wall of the groove 6. The fixing part 41 restricts the heating element 5 within the groove 6, making it difficult for the heating element 5 to fall out of the groove 6, and it will not affect the heating element 5 when the cabinet door 20 is foaming. In this embodiment of the utility model, the heating element 5 is a carbon fiber heating wire, which provides uniform heating and energy saving.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. The scope of protection of this utility model is defined by the appended claims, specification, and their equivalents.
