Description

Technical Field

[0001] This invention relates to product warehousing, and more specifically to warehousing equipment. Background Technology

[0002] The patent document with authorization announcement number CN 220765382 U discloses a low-temperature storage device that avoids removing all products on both sides of the storage chamber when taking out or putting out products on one side, thus preventing products that do not need to be taken out from being exposed to the external environment for a long time and becoming contaminated.

[0003] The aforementioned low-temperature storage equipment includes a storage chamber and a refrigeration compressor unit. The storage chamber has openings at both ends. The refrigeration compressor unit is installed at the top of the storage chamber and is used for refrigeration inside the storage chamber. It also includes a partition, a drive mechanism, two sets of moving plates, multiple sets of placement plates, multiple sets of connecting components, and two sets of sealing plates. The partition is vertically fixed in the middle of the storage chamber. The drive mechanism is installed at the rear end of the storage chamber and is used to drive the moving plates to move. The two sets of moving plates are located on the left and right sides of the storage chamber, respectively.

[0004] When the sealing plate is opened, the inside of the storage compartment is connected to the outside atmosphere, causing the cold air generated by the refrigeration compressor unit to escape. This raises the temperature inside the storage compartment, prompting the refrigeration compressor unit to accelerate its operation upon detecting the temperature drop. This is detrimental to energy conservation. Summary of the Invention

[0005] The technical problem solved by this invention is to improve upon existing low-temperature storage equipment so that the cold air generated by the refrigeration compressor unit will not overflow when the sealing plate is opened, thus saving energy.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-efficiency and energy-saving low-temperature storage equipment, comprising a storage chamber and a refrigeration compressor unit. The storage chamber is equipped with a partition, and an opening is provided at one end of the storage chamber. The refrigeration compressor unit is installed outside the storage chamber and is used for refrigeration inside the storage chamber. A storage rack is movably fitted inside the storage chamber. The storage rack includes a movable plate located inside the storage chamber and a sealing plate located outside the storage chamber. The sealing plate can seal the storage chamber. The cold air pipe of the refrigeration compressor unit extends downward into the partition, and a... A top pressure pipe is installed, with a vertical partition. The top pressure pipe is connected to the cooling pipe. A cooling air passage is provided on the movable plate, and a cooling air sealing assembly is fitted in the cooling air passage. The cooling air sealing assembly includes a cooling air pipe fitted in the cooling air passage, a cooling air passage plug fixed to one end of the cooling air pipe, and a return spring used in conjunction with the cooling air pipe. The cooling air pipe has a cooling air passage. Under the action of the return spring, the cooling air passage plug closes the cooling air passage. The cooling air pipe and the top pressure pipe are set accordingly, and the top pressure pipe can press against one end of the cooling air pipe to open the cooling air passage plug.

[0007] According to the above technical solution, the storage rack is located inside the storage compartment, the movable plate moves closer to the partition, the top pressure pipe presses against one end of the cold air exhaust pipe, the return spring is compressed, the cold air through hole plug opens the cold air through hole, and the cold air generated by the refrigeration compressor unit enters the space between the movable plate and the sealing plate through the cold air pipe, the top pressure pipe, the cold air exhaust pipe, and the cold air exhaust hole. The product is stored in this space and the product is preserved at a low temperature.

[0008] When retrieving a product, the storage rack is moved out of the storage compartment, the moving plate moves away from the partition, and one end of the cold air exhaust pipe detaches from the top pressure pipe. Under the action of the return spring, the cold air exhaust pipe returns to its original position, and the cold air through-hole plug moves accordingly, sealing the cold air through-hole. The cold air generated by the refrigeration compressor unit enters the space between the partition and the moving plate through the cold air pipe and the top pressure pipe. Because the cold air through-hole is sealed, the cold air cannot overflow through the moving plate.

[0009] After the product is retrieved, the storage rack is moved into the storage compartment, the moving plate moves closer to the partition, the top pressure pipe presses against one end of the cold air exhaust pipe, the return spring is compressed, the cold air through hole plug opens the cold air through hole, and the cold air generated by the refrigeration compressor unit enters the space between the moving plate and the sealing plate through the cold air pipe, the top pressure pipe, the cold air exhaust pipe, and the cold air exhaust hole. The product is stored in this space and is kept at a low temperature.

[0010] During the process of the storage rack moving into the storage compartment and the moving plate approaching the partition, the cold air between the moving plate and the partition is compressed, and the cold air pressure increases. When this pressure exceeds the elastic force of the return spring, the cold air may force open the cold air vent plug and overflow into the space between the moving plate and the sealing plate. At this time, during the process of the storage rack moving into the storage compartment, the space between the moving plate and the sealing plate is precisely where cold air is needed. Moreover, the process of the storage rack moving into the storage compartment is short, and the amount of cold air overflowing into the storage compartment is small.

[0011] To prevent the cold air vents from opening during the movement of the storage rack into the storage compartment, a return spring with greater elasticity can be selected to prevent the cold air passage blockage from being blown open by the cold air and overflowing between the moving plate and the sealing plate.

[0012] The air conditioning pipe is equipped with a spring retaining ring on its outer perimeter. One end of the air conditioning through hole is equipped with an inner sealing ring, and the other end of the air conditioning through hole is equipped with an outer sealing ring. The spring retaining ring and the return spring are located between the inner sealing ring and the outer sealing ring. One end of the return spring abuts against the spring retaining ring, and the other end of the return spring abuts against the outer sealing ring.

[0013] The movable plate has a recessed structure, and the cold air vent plug is located in the recessed structure. The recessed structure hides the cold air vent plug, preventing the products in the storage rack from being affected by the protruding cold air vent plug on the movable plate.

[0014] The storage compartment has a limiting structure at its end. When the storage rack moves to its extreme position, the moving plate abuts against the limiting structure. The limiting structure restricts the maximum displacement of the storage rack.

[0015] The storage compartment has openings at both ends, and the partition is located in the middle of the storage compartment, dividing it into two chambers, left and right, each of which is equipped with a storage rack.

[0016] The storage compartment is equipped with a lead screw drive mechanism on its exterior. The moving plate has a drive section with threaded holes, extending into the housing of the lead screw drive mechanism and connecting to the lead screw. Two sets of lead screw drive mechanisms are used, each cooperating with the moving plates of two storage racks. Each lead screw drive mechanism is equipped with a motor. A support plate is located in the middle of the housing of the lead screw drive mechanism, and one end of the lead screw of both sets of drive mechanisms is pivotally connected to the support plate. The housing of the lead screw drive mechanism has buttons for driving the mechanism forward and backward.

[0017] Technical effects of the present invention:

[0018] First, when the storage compartment is opened by the sealing plate of the storage rack, the cold air generated by the refrigeration compressor unit will not escape, thus achieving energy saving.

[0019] Secondly, after the storage rack is reset into the storage compartment, the high-pressure cold air compressed by the moving plate can quickly enter the storage rack space to cool the product, which has a highly efficient effect. Attached Figure Description

[0036] Combination Figure 1 , Figures 4 to 6 A high-efficiency and energy-saving cryogenic storage device includes a storage chamber 10 and a refrigeration compressor unit 20. The storage chamber has a partition 11 and an opening at one end. The refrigeration compressor unit is installed outside the storage chamber and is used for refrigeration inside the storage chamber. A storage rack 30 is movably fitted inside the storage chamber. The storage rack includes a movable plate 31 located inside the storage chamber and a sealing plate 32 located outside the storage chamber. The sealing plate can seal the storage chamber. A cold air pipe 21 of the refrigeration compressor unit extends downward into the partition. A top pressure pipe 22 is installed on the partition, perpendicular to the partition, and connected to the cold air pipe. The movable plate 31 has a cold air passage 311, in which a cold air sealing assembly 40 is fitted. The cold air sealing assembly includes a cold air exhaust pipe 41 fitted in the cold air passage, a cold air passage plug 42 fixed to one end of the cold air exhaust pipe, and a return spring 43 used in conjunction with the cold air exhaust pipe. The cold air exhaust pipe has a cold air exhaust hole 44. Under the action of the return spring 43, the cold air passage plug closes the cold air passage; the cold air pipe 41 and the top pressure pipe 22 are correspondingly arranged, and the top pressure pipe can press against one end of the cooling pipe to open the cold air passage plug.

[0037] like Figure 6The outer periphery of the air conditioning pipe 41 is provided with a spring retaining ring 411, one end of the air conditioning through hole 311 is provided with an inner sealing ring 45, and the other end of the air conditioning through hole is provided with an outer sealing ring 46. The spring retaining ring and the return spring 43 are located between the inner sealing ring and the outer sealing ring. One end of the return spring abuts against the spring retaining ring, and the other end of the return spring abuts against the outer sealing ring.

[0038] The movable plate 31 is provided with a recessed structure 312, and the cold air passage plug 42 is located in the recessed structure.

[0039] like Figure 4 The storage compartment 10 is provided with a limiting structure 12 at its end. When the storage rack 30 moves to its limit position, the moving plate abuts against the limiting structure.

[0040] The storage compartment 10 has openings at both ends, and the partition 11 is located in the middle of the storage compartment, dividing the storage compartment into two chambers, left and right, each of which is equipped with a storage rack 30.

[0041] like Figures 1 to 3 The storage compartment 10 is provided with a lead screw drive mechanism 50 on its exterior. The moving plate 31 is provided with a drive part 313. The drive part is provided with a threaded hole 314. The drive part extends into the housing 51 of the lead screw drive mechanism and is connected to the lead screw.

[0042] refer to Figure 7 , Figure 8 The storage rack 30 is located inside the storage compartment 10. The movable plate 31 moves closer to the partition 11. The top pressure pipe 22 presses against one end of the cold air exhaust pipe 41, the return spring 43 is compressed, and the cold air through hole plug 42 opens the cold air through hole 311. The cold air generated by the refrigeration compressor unit 20 enters the space between the movable plate 31 and the sealing plate 32 through the cold air pipe 21, the top pressure pipe 22, the cold air exhaust pipe 41, and the cold air exhaust hole 44. The product is stored in this space and is preserved at a low temperature.

[0043] refer to Figures 4 to 6 When retrieving a product, the storage rack 30 moves out of the storage compartment 10, the moving plate 31 moves away from the partition 11, and one end of the cold air exhaust pipe 41 disengages from the top pressure pipe 22. Under the action of the return spring 43, the cold air exhaust pipe 41 returns to its original position, and the cold air through-hole plug 42 moves accordingly, sealing the cold air through-hole 311. The cold air generated by the refrigeration compressor unit 20 enters the space between the partition 11 and the moving plate 31 through the cold air pipe 21 and the top pressure pipe 22. Since the cold air through-hole 311 is sealed, the cold air cannot overflow through the moving plate 31.

[0044] After the product is retrieved, the storage rack 30 moves into the storage compartment 10, the moving plate 31 moves closer to the partition 11, the top pressure pipe 22 presses against one end of the cold air exhaust pipe 41, the return spring 43 is compressed, the cold air through hole plug 42 opens the cold air through hole 311, and the cold air generated by the refrigeration compressor unit 20 enters the space between the moving plate 31 and the sealing plate 32 through the cold air pipe 21, the top pressure pipe 22, and the cold air exhaust pipe 41. The product is stored in this space and is kept at a low temperature.

[0045] During the process of the storage rack 30 moving into the storage compartment 10 and the moving plate 31 approaching the partition 11, the cold air between the moving plate and the partition is compressed, and the cold air pressure increases. When this pressure exceeds the elastic force of the return spring 43, the cold air may force open the cold air passage plug 42 and overflow into the space between the moving plate 31 and the sealing plate 32. At this time, during the process of the storage rack 30 moving into the storage compartment 10, it is precisely the space between the moving plate 31 and the sealing plate 32 that needs cold air to enter. Moreover, the process of the storage rack 30 moving into the storage compartment is short, and the amount of cold air overflowing from the storage compartment 10 is small.

[0046] Alternatively, to prevent the cold air vent 311 from opening during the movement of the storage rack 30 into the storage chamber, a return spring 43 with greater elasticity can be selected to prevent the cold air passage plug 42 from being forced open by the cold air and overflowing between the moving plate 31 and the sealing plate 32. After the storage rack 30 is reset into the storage chamber 10, the pressure pipe 22 pushes the cold air exhaust pipe 41, opening the cold air vent 311. The high-pressure cold air compressed by the moving plate 31 can then quickly enter the space of the storage rack 30 to cool the product.

[0047] The recessed structure 312 on the movable plate 31 hides the cold air vent plug 42, preventing the products inside the storage rack 30 from being affected by the cold air vent plug protruding from the movable plate.

[0048] The limiting structure 12 of the storage compartment 10 limits the maximum displacement of the storage rack 30.

[0049] Two sets of lead screw drive mechanisms 50 are used, each cooperating with the movable plates 31 of the two storage racks 30. Each lead screw drive mechanism is equipped with a motor 52. A support plate 54 is set in the middle of the housing 51 of the lead screw drive mechanism, and one end of the lead screw of the two sets of lead screw drive mechanisms is pivotally connected to the support plate. The housing 51 of the lead screw drive mechanism is equipped with buttons 53 for driving the lead screw drive mechanism forward and backward.

[0050] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
