Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to an energy-saving freezer door sealing structure. Background Technology

[0002] In commercial and residential refrigeration equipment, the sealing performance of the freezer door directly affects the overall insulation effect and energy consumption level. During operation, the freezer maintains a low-temperature environment inside, while the external environment is warmer and more humid. If the door seal is poor, hot, humid air from outside will continuously seep into the freezer, increasing the compressor's start-stop frequency and operating load, and significantly increasing energy consumption.

[0003] Currently, most freezers use PVC or TPE door seals with built-in magnetic strips as the main sealing structure. However, these door seals are prone to hardening, shrinking, and losing elasticity in low-temperature environments. Furthermore, frequent opening and closing of the door can cause permanent deformation of the seals, affecting the sealing effect.

[0004] Therefore, an energy-saving freezer door sealing structure needs to be designed to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of poor deformation resistance of door seal strips, which affects the sealing effect, this utility model provides an energy-saving refrigerator door sealing structure.

[0006] The technical solution is as follows: An energy-saving refrigerator door sealing structure includes a cabinet body, support blocks, a cabinet door, a base frame, flexible magnetic strips, baffles, locking blocks, a skeleton, fixing bolts, and a sealing lip. Support blocks are fixedly connected to the upper and lower sides of the left front of the cabinet body. The cabinet door is rotatably connected between the two support blocks. The base frame is fixedly connected to the rear side of the cabinet door. A magnetic groove is opened on the rear side of the base frame, and a flexible magnetic strip is placed in the magnetic groove. A baffle is fixedly connected to the rear of the magnetic groove. Locking blocks are fixedly connected to the left and right sides of the upper and lower rear sides of the baffle. A skeleton is slidably contacted between the rear parts of the four locking blocks. The skeleton is made of rigid material. Fixing bolts are threadedly connected between the four locking blocks and the skeleton. A sealing lip is provided on the rear side of the base frame, and the skeleton is located inside the sealing lip.

[0007] Furthermore, it also includes an observation panel, which is located in the middle of the cabinet door and is made of transparent material.

[0008] Furthermore, it also includes a handle, with a handle fixedly connected to the front right side of the cabinet door.

[0009] Furthermore, it also includes retaining ribs, with retaining ribs provided on both sides of the magnetic groove, and a flexible magnetic strip located between the two retaining ribs.

[0010] Furthermore, it also includes a second sealing lip and an elastic support rib. The second sealing lip is provided on the inner side of the base frame, and the elastic support rib is provided between the second sealing lip and the first sealing lip.

[0011] Furthermore, it also includes a locking rod and a limiting block. The locking rod is rotatably connected to the right side of the cabinet door, and the limiting block is fixedly connected to the middle of the right side of the cabinet body. The rear side of the locking rod is located on the upper inner side of the limiting block.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a skeleton, a locking block and a fixing bolt, this utility model ensures that the sealing lip one maintains its original shape and fitting pressure during long-term use, avoiding the sealing failure caused by the collapse of traditional soft door seals. Furthermore, through the cooperation of sealing lip one, sealing lip two and elastic support ribs, a double-lip seal and elastic rebound effect are formed, which prolongs the penetration channel for the exchange of hot and cold air, effectively blocking the leakage of cold air inside the cabinet and the intrusion of hot and humid air from the outside, and reducing the energy consumption of the freezer.

[0013] 2. This utility model precisely embeds the flexible magnetic strip into the magnetic groove and limits its position with side retaining bars and rear baffle to prevent displacement or twisting during use. This ensures that the magnetic strip is evenly and stably attracted to the metal frame of the cabinet. Furthermore, the cooperation of the rotatable retaining rod and the limiting block provides additional physical locking force on the basis of magnetic attraction closure, effectively overcoming cabinet door loosening or accidental opening caused by negative pressure inside the cabinet or external vibration, thus improving sealing reliability. At the same time, a transparent observation plate is provided in the middle of the cabinet door to reduce the frequency of unnecessary door opening and further reduce cold loss.

Detailed Implementation

[0019] Example: An energy-saving refrigerator door sealing structure, such as Figures 1-4As shown, the cabinet includes a cabinet body 1, support blocks 2, cabinet doors 3, base frame 6, flexible magnetic strips 8, baffles 9, locking blocks 10, skeleton 11, fixing bolts 12, and sealing lips 13. Support blocks 2 are bolted to the upper and lower sides of the left front part of the cabinet body 1. The cabinet door 3 is rotatably connected between the two support blocks 2. The base frame 6 is bolted to the rear side of the cabinet door 3. A magnetic groove is opened on the rear side of the base frame 6, and a flexible magnetic strip 8 is placed in the magnetic groove. The baffle 9 is fixedly connected to the rear part of the magnetic groove. The left and right sides of the upper and lower parts of the rear side of the baffle 9 are fixedly connected to the locking blocks 10. The skeleton 11 is slidably contacted between the rear parts of the four locking blocks 10. The skeleton 11 is made of rigid material. The four locking blocks 10 and the skeleton 11 are threadedly connected to the fixing bolts 12. The sealing lip 13 is provided on the rear side of the base frame 6, and the skeleton 11 is located inside the sealing lip 13.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes an observation panel 4, which is located in the middle of the cabinet door 3. The observation panel 4 is made of transparent material.

[0021] like Figure 1 and Figure 4 As shown, it also includes a handle 5, which is fixedly connected to the right side of the front of the cabinet door 3.

[0022] like Figure 2 As shown, it also includes retaining ribs 7, with retaining ribs 7 provided on both sides of the magnetic groove, and the flexible magnetic strip 8 located between the two retaining ribs 7.

[0023] like Figure 2 As shown, it also includes a second sealing lip 14 and an elastic support rib 15. The second sealing lip 14 is provided on the inner side of the base frame 6. The second sealing lip 14 contacts the inner side of the cabinet 1. The elastic support rib 15 is provided between the second sealing lip 14 and the first sealing lip 13.

[0024] like Figure 4 As shown, it also includes a locking rod 16 and a limiting block 17. The locking rod 16 is rotatably connected to the right side of the cabinet door 3, and the limiting block 17 is fixedly connected to the middle right side of the cabinet body 1 by bolts. The rear side of the locking rod 16 is located on the upper inner side of the limiting block 17.

[0025] When the freezer needs to be closed, the operator pulls the handle 5 to rotate the door 3 around the support block 2, causing the door 3 to close towards the cabinet body 1. During the closing process, the base frame 6 on the rear side of the door 3 moves closer to the inside of the cabinet body 1. The base frame 6 has a sealing lip 13 on the rear side, and a frame 11 is embedded in its inner side. The frame 11 is connected to the base frame 6 through four locking blocks 10 and is locked by the screw bolts 12 to ensure the overall structure is stable. The frame 11 is made of rigid material and is used to support the shape of the sealing lip 13 to prevent it from collapsing or permanently deforming under long-term compression or low temperature environment, thereby maintaining the effective fit between the sealing lip 13 and the cabinet body 1.

[0026] The base frame 6 also has a second sealing lip 14 inside, which directly contacts the inside of the cabinet 1 to form the first sealing barrier. The first sealing lip 13 serves as the outer seal, cooperating with the front edge of the cabinet 1 to form the second sealing path. An elastic support rib 15 is provided between the first sealing lip 13 and the second sealing lip 14. This support rib provides continuous rebound force, pushing the first sealing lip 13 and the second sealing lip 14 to tightly fit the corresponding parts of the cabinet 1, reducing cold air leakage.

[0027] Meanwhile, a flexible magnetic strip 8 is embedded in the magnetic groove on the rear side of the base frame 6. The magnetic strip is limited by the clamps 7 on both sides to prevent it from moving laterally during use. The baffle 9 at the rear of the magnetic groove further constrains the position of the magnetic strip. When the cabinet door 3 is closed, the flexible magnetic strip 8 is attracted to the metal frame of the cabinet 1 by magnetic force, generating a uniform attraction force to ensure that the sealing lip around the entire door is under consistent pressure and to avoid local detachment.

[0028] To enhance the locking reliability after closing, a rotatable latch 16 is provided on the right side of the cabinet door 3, and a limit block 17 is fixed at the corresponding position on the right side of the cabinet body 1. After the cabinet door 3 is fully closed, the latch 16 is rotated so that its rear side engages with the upper inner side of the limit block 17 to form a mechanical lock, preventing the cabinet door 3 from being accidentally opened due to negative pressure inside the cabinet or external vibration.

[0029] A transparent observation panel 4 is provided in the middle of the cabinet door 3, which allows users to check the status of the items inside without opening the cabinet door 3, reducing unnecessary opening times and indirectly reducing cold loss.
