Description

Technical Field

[0001] This utility model relates to the field of medical refrigerator technology, specifically a sealed and leak-proof device for energy-saving cabinets. Background Technology

[0002] Many active ingredients in medications decompose at high temperatures, leading to reduced or even loss of efficacy, such as insulin, antibiotics, and biologics. Therefore, some medications need to be stored in a refrigerated cabinet.

[0003] A search revealed a medical refrigerator for storing medicines in patent application CN107421197A. The refrigerator includes a cabinet and a movable door. The cabinet's internal cavity contains refrigeration pipes, a heating plate, a placement plate, and a breathable partition. A temperature and humidity sensor is installed in the placement plate. The cabinet also contains an ultraviolet lamp and a lighting lamp. A hollow support base is located at the bottom of the cabinet, housing a compressor, a cooling motor, an electric heater, and a rechargeable battery. The refrigerator also includes a cooler located inside the casing, a control panel, a voice alarm, and a controller. The cooler is connected to the compressor via refrigeration pipes, and the heating plate is electrically connected to the electric heater.

[0004] The medical refrigerator uses an integrated door for opening and closing. The refrigerator has multiple compartments inside. When medicine is taken out, the door is opened and a large amount of cold air from multiple compartments will leak out. When medicine is taken out frequently, the temperature inside the refrigerator fluctuates greatly, which not only affects accurate temperature control, but also consumes more energy and affects the refrigeration effect of medicine. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a cabinet energy-saving airtight leak-proof device, including a refrigerator 1, an outer cabinet door 2 hinged to one side of the refrigerator 1, and a number of partitions 3 equidistantly arranged in the Z-axis direction in the inner cavity of the refrigerator 1. A placement compartment 4 is formed between adjacent partitions 3 and between the partitions 3 and the inner cavity of the outer cabinet door 2. Each placement compartment 4 is provided with an airtight structure 5 to prevent cold air leakage at one end near the outer cabinet door 2.

[0025] The refrigerator 1 is divided into multiple compartments equidistantly along the Z-axis, each compartment equipped with an independent inner door 8 and a sealing structure 5. When medicines need to be stored or retrieved from a certain compartment, only the inner door 8 of the corresponding compartment needs to be opened, while the other compartments remain sealed. The outer door 2 and the insulation and refrigeration system inside the refrigerator 1 are the same as those in existing technologies.

[0026] The sealed structure 5 includes an upper hinged plate 6. The top of the upper hinged plate 6 is provided with a rotating structure 7 for rotating connection with the refrigerator 1. The sides of the refrigerator 1 are provided with positioning structures for positioning the upper hinged plate 6 after rotation. The middle of the upper hinged plate 6 is provided with an inner cabinet door 8 and a sliding structure 9 for pushing and pulling the inner cabinet door 8 left and right.

[0027] The upper lifting plate 6 provides an installation base for the inner cabinet door 8. When a large number of medicines are taken out and put in at one time, the upper lifting plate 6 can also be lifted upward by rotating the structure 7, so that both inner cabinet doors 8 can be lifted up together to facilitate the taking out and putting in medicines. The positioning structure limits the upper lifting plate 6 when it is not rotated.

[0028] The push-pull structure 9 includes an upper limit plate 901 and a lower limit plate 902. A groove 903 is provided in the middle of the upper lifting plate 6. The upper limit plate 901 and the lower limit plate 902 are respectively fixed to the upper and lower surfaces of the inner wall of the groove 903. A first limiting groove 904 and a second limiting groove 905 are provided on one side of both the upper limit plate 901 and the lower limit plate 902.

[0029] Each set of sealed structures 5 has two sets of inner cabinet doors 8, with the two sets of inner cabinet doors 8 located in the first limiting groove 904 and the second limiting groove 905, respectively.

[0030] By setting the first limiting groove 904 and the second limiting groove 905, the two inner cabinet doors 8 can be opened by sliding.

[0031] The rotating structure 7 includes a rotating rod 701. The top end of the upper lifting plate 6 is fixedly connected to the outer wall of the rotating rod 701, and the two ends of the rotating rod 701 are rotatably connected to the inner wall of the refrigerator 1.

[0032] The rotating structure 7 also includes a top support block 702. One end of the top support block 702 is fixed with a rotating shaft 703. The rotating shaft 703 is rotatably connected to the inner wall of the refrigerator 1. The other end of the top support block 702 is threaded with a positioning pin 704. The inner walls on both sides of the refrigerator 1 are provided with positioning holes 705 for the positioning pin 704 to be inserted.

[0033] When the upper lift plate 6 is rotated upward, the rotating rod 701 rotates inside the refrigerator 1. The top support block 702 is manually rotated, and the top support block 702 rotates around the rotating shaft 703. The positioning pin 704 is screwed into the positioning hole 705, so that one end of the top support block 702 supports the bottom of the upper lift plate 6.

[0034] The positioning structure includes magnetic locating pieces 12, which are fixed on both sides of the upper lifting plate 6 and both sides of the inner cavity of the refrigerator 1. The magnetic locating pieces 12 on both sides of the upper lifting plate 6 and the magnetic locating pieces 12 on both sides of the inner cavity of the refrigerator 1 attract each other.

[0035] By setting magnetic plates 12, when the upper lifting plate 6 is not rotated, the magnetic plates 12 on both sides of the upper lifting plate 6 are attracted to the two sides of the inner wall of the refrigerator 1.

[0036] Both sides of the inner cabinet door 8 are fixed with insulation boards 10 to reduce the loss of cold air, and rubber strips 11 are fixed on the adjacent side of the two inner cabinet doors 8.

[0037] The insulation board 10 is made of polyurethane foam to reduce heat transfer, and the rubber strip 11 is made of EPDM rubber, which is suitable for temperatures ranging from -50℃ to +120℃. It maintains elasticity in the low-temperature environment of the refrigerator 1 and avoids hardening and cracking.

[0038] When in use, place the medicines into the corresponding storage compartments 4 as needed. When you need to take out or put out the medicines, open the outer cabinet door 2 and push or pull open the inner cabinet door 8 of the corresponding storage compartment 4.

[0039] When taking out a large amount of medicine at one time, manually lift the upper flap 6 upwards. When the upper flap 6 rotates upwards, the rotating rod 701 rotates inside the refrigerator 1. Manually rotate the top support block 702. The top support block 702 rotates around the rotating shaft 703. Screw the positioning pin 704 into the positioning hole 705 so that one end of the top support block 702 supports the bottom of the upper flap 6. At the same time as the upper flap 6 is lifted upwards, the two inner cabinet doors 8 installed on the upper flap 6 open upwards simultaneously to facilitate taking out and putting out medicine.

[0040] Compared to traditional single-door opening methods, this device can reduce cold air leakage and lower temperature fluctuations.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
