Description

Technical Field

[0001] This utility model relates to the field of preservation equipment technology, specifically a large-capacity, high-efficiency vacuum low-temperature storage box. Background Technology

[0002] With the fast pace of modern life, people's demand for food preservation is increasing. Low-temperature storage boxes, as common food preservation equipment in homes and businesses, directly affect the preservation quality and food safety of food. While traditional low-temperature storage boxes can extend the shelf life of food to some extent, they still have some obvious shortcomings. First, the preservation effect of traditional storage boxes is limited, often unable to maintain the freshness and nutrition of food for extended periods. Second, traditional storage boxes are not airtight enough, easily allowing air and moisture to intrude, thus affecting the preservation effect. Furthermore, traditional storage boxes also have problems with refrigeration efficiency and energy consumption, failing to meet modern consumers' demands for high efficiency and energy saving. Utility Model Content

[0030] Large-capacity, high-efficiency vacuum low-temperature storage box, such as Figures 1-3As shown, the system includes a large-capacity cabinet 10 for fresh food storage and a refrigeration unit 50 mounted on the outer wall of the cabinet 10. A vacuum pump 30 is installed on the top of the cabinet 10. The cabinet 10 is divided into two fresh food storage areas 12 by a partition 11. Each fresh food storage area 12 has several evenly spaced shelf racks 13. Each fresh food storage area 12 is equipped with a sealed door 20, and a U-shaped pull rod 22 is installed on the outer wall of each sealed door 20. A sealing ring 23 is installed between the edge of the sealed door 20 and the cabinet 10. The suction end of the vacuum pump 30 is connected to the interior of the two fresh food storage areas 12 through two sets of vacuum pipes 32. An air inlet pipe 40 is installed on the outer wall of each fresh food storage area 12, and a control valve 41 is installed on the air inlet pipe 40. The large-capacity cabinet 10 provides ample fresh food storage space. The refrigeration unit 50 mounted on the outer wall of the cabinet 10 has... The temperature inside the cabinet 10 is effectively reduced to achieve low-temperature storage. The vacuum pump 30 installed on the top of the cabinet 10 is connected to the interior of the two storage zones 12 through two sets of vacuum pipes 32, which effectively extracts the air from the storage zones 12 to achieve a vacuum state and extend the shelf life of food. The partition 11 divides the cabinet 10 into two storage zones 12, improving space utilization. Several evenly spaced shelf racks 13 are set in each storage zone 12 to facilitate the placement and retrieval of food. Each storage zone 12 is equipped with a sealed door 20, which, together with the U-shaped pull rod 22 installed on the outer wall of the sealed door 20 and the sealing ring 23 between the edge and the cabinet 10, ensures the airtightness of the storage zone 12. The air inlet pipe 40 and control valve 41 installed on the outer wall of each storage zone 12 can inject an appropriate amount of gas into the storage zone 12 when needed to regulate the internal environment.

[0031] Furthermore, casters 14 are installed at the four corners of the bottom of the box 10, making the large-capacity, high-efficiency vacuum low-temperature storage box easy to move and transport, thus improving its ease of use.

[0032] Specifically, a transparent observation window 21 for observing the interior is provided at the center of the sealed door 20. The transparent observation window 21 is made of transparent double-layer tempered glass and is 2-4cm thick, so that users can clearly observe the food inside the storage area 12, which is convenient for management and retrieval. At the same time, the double-layer tempered glass design also improves the durability and safety of the observation window.

[0033] Among them, the sealing ring 23 is made of food-grade silicone and the thickness of the sealing ring 23 is 2-5mm, which ensures the sealing performance of the storage area 12, effectively prevents the intrusion of air and moisture, extends the shelf life of food, and also meets food safety requirements.

[0034] It is worth noting that a motor 31 is installed on the vacuum pump 30, which provides a stable power source for the vacuum pump 30, making the vacuuming process more efficient and stable, and improving the preservation effect.

[0035] In addition, the refrigeration unit 50 is connected to the interior of the two fresh food storage zones 12, thereby achieving refrigeration of the two fresh food storage zones 12 and ensuring that the temperature in each fresh food storage zone 12 can be effectively controlled, thus improving the accuracy and efficiency of fresh food storage.

[0036] The working principle of this large-capacity, high-efficiency vacuum low-temperature storage box:

[0037] First, open the sealed door 20 and place the food that needs to be stored on the shelf 13. The shelf 13 in each storage area 12 is designed to be evenly spaced, which makes it convenient to place and take out the food. When placing the food, you can observe the inside of the storage area 12 through the transparent observation window 21 to ensure that the food is placed properly.

[0038] Next, close the sealed door 20 and check whether the sealing ring 23 is tightly fitted to ensure the airtightness of the storage area 12. Then, start the motor 31 on the vacuum pump 30. The vacuum pump 30 extracts the air from the two storage areas 12 through two sets of vacuum tubes 32 to achieve a vacuum state. This step can effectively extend the shelf life of food.

[0039] After vacuuming is completed, control valve 41 is opened as needed, and an appropriate amount of gas is injected into the fresh storage area 12 through air inlet pipe 40 to regulate the internal environment. At the same time, refrigeration unit 50 is started to cool the two fresh storage areas 12 and maintain a low temperature.

[0040] During use, the inside of the storage area 12 can be observed at any time through the transparent observation window 21 to understand the storage status of the food. If the storage box needs to be moved, it can be easily moved by the wheels 14.

[0041] 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 preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
