Description

Technical Field

[0001] The present application relates to the technical field of low-temperature storage equipment for items, and in particular to a thermal insulation refrigerator. Background Art

[0002] At present, the thermal insulation freezer is a device used to store and maintain low-temperature or high-temperature items. It has good thermal insulation performance and can effectively isolate the internal temperature from the external environment to keep the temperature of the items stable.

[0003] Insulated freezers are usually made of materials with good thermal insulation properties, such as polyurethane foam or other insulating materials. These materials have low thermal conductivity, which can prevent the conduction of heat, thereby reducing the change of internal temperature. Insulated freezers are widely used in food, medicine, chemical and other industries to store and transport items that need to be kept at a specific temperature. For example, refrigerated freezers are used to store food, medicine and other items that need to be kept at low temperatures, while insulated freezers are used to store items that need to be kept at high temperatures, such as hot food, temperature-sensitive medicines, etc. The use of insulated freezers can effectively extend the shelf life of items and maintain their quality and safety. At the same time, it can also save energy and reduce energy consumption, because insulated freezers can reduce temperature changes, thereby reducing the energy demand for cooling or heating.

[0004] Regarding the above-mentioned related technologies, when using the thermal insulation refrigerator to store medicines, there are many types of medicines, and multiple types of medicines are placed in the same storage box. When the user takes a certain medicine, other types of medicines are exposed to the air, which can easily affect other medicines and reduce the refrigeration effect of other medicines. Summary of the Invention

[0005] In order to reduce the impact on other medicines when taking a certain medicine, the present application provides a thermal insulation refrigerator.

[0006] This application provides a thermal insulation refrigerator, which adopts the following technical solutions:

[0008] By adopting the above technical solution, the staff starts the refrigeration mechanism, and the refrigeration mechanism transmits cold air to the box body, thereby realizing the refrigeration of the medicines, and the medicines are placed in different boxes according to their types. When the staff needs to take one of the medicines, the staff turns the handle above the medicine, and the handle drives the rotating rod to rotate, and the rotating rod drives the connecting plate to rotate, and the connecting plate is plugged into the plug-in groove of the protrusion, and the box cover is opened.

When a large amount of medicine is contained in the box and some of it needs to be removed, the cold air continues to refrigerate the other medicines, thereby helping to reduce the impact on other medicines. The support net supports the medicines, helping to prevent the medicines from being transferred into the delivery pipe.

[0013] Optionally, a driving rack is provided on the side of the opening and closing plate close to the box body, and the driving rack is vertically arranged. The lower end of the box body is rotatably connected to a driving gear, which is engaged with the driving rack.

[0018] By adopting the above technical solution, during refrigeration, the refrigerant in the liquid storage tank absorbs heat and refrigerates in the evaporator in liquid form, and the low-temperature liquid absorbs the latent heat of vaporization and becomes refrigerant gas, which is sucked into and compressed by the compressor. The pressure and temperature of the compressed gas increase, and then it flows into the condenser for condensation. The condensed high-temperature and high-pressure liquid is dried and filtered by the drying filter and then returned to the liquid storage tank, thus completing the refrigeration cycle.

The connecting plate 323 is inserted into the insertion slot of the protrusion 324. When the connecting plate 323 rotates into the protrusion 324, the baffle 325 blocks the connecting plate 323. The driving cylinder 31 is activated, and the piston rod of the driving cylinder 31 extends, driving the box cover 13 to rise.

The opening and closing plate 33 is stationary, and the box body 121 and the opening and closing plate 33 are relatively displaced. The box body 121 rises along the height direction of the limit block 34, and then the box body 121 is opened during the rising process.
