[0037] Figure 1 A cross-sectional view of a refrigeration device according to an embodiment of the present invention is shown. The refrigeration device includes a refrigeration tank 2, a switching assembly 3, a refrigerator 5, piping 6, and a telescopic device 415.

[0038] like Figure 2 - Figure 6As shown, a plurality of refrigerator boxes 5 are arranged around the refrigeration tank 2. A plurality of pipe connection ports 215 are provided at the bottom of the refrigeration tank 2, and each of the pipe connection ports 215 corresponds to one of the refrigerator boxes 5. A plurality of pipe connection ports 513 are provided at the bottom of the refrigerator boxes 5, and each of the pipe connection ports 215 corresponds to one of the pipe connection ports 513. One end of the pipe 6 is connected to the pipe connection port 215, and the other end of the pipe 6 is connected to the pipe connection port 513 corresponding to the pipe connection port 215. A plurality of switching components 3 are slidably installed in the pipe connection ports 215. A plurality of telescopic devices 415 are installed on the refrigeration tank 2. The telescopic devices 415 are used to drive the switching components 3 to slide in the pipe connection ports 215. A refrigerator is provided inside the refrigeration tank 2.

[0039] In this embodiment, the samples or medicines to be stored are placed in the refrigerator 5, and the refrigerator in the refrigeration tank 2 is turned on to cool them. The cold air in the refrigeration tank 2 enters the refrigerator 5 through the pipe connection port 215 and the pipe 6. When the number of samples is small, the medicines can be placed in one of the refrigerators 5. The switching components 3 in the other refrigerators 5 are controlled to block the pipe connection port 215 under the action of the telescopic device 415. At this time, the cold air in the refrigeration tank 2 will flow into one refrigerator 5, the cooling space is reduced, the cooling effect is improved, and no energy waste is caused.

[0040] It should be noted that the telescopic device 415 can be installed at the top of the refrigeration tank 2, at the bottom of the refrigeration tank 2, or inside the refrigeration tank 2; the switching component 3 is connected to the output shaft of the telescopic device 415, and the telescopic device 415 drives the switching component 3 to slide within the pipe connection port 215, thereby blocking or removing the switching component 3 from the pipe connection port 215, thus controlling the connection or disconnection between the multiple refrigerators 5 and the refrigeration tank 2. Figure 1 and Figure 2 As shown in the schematic diagram, the two ends of the pipe 6 are fixed to the bottom of the refrigerator 5 and the refrigeration tank 2, respectively. There are four pipes 6, which are used to connect the refrigerator 5 and the refrigeration tank 2.

[0041] In one embodiment of the present invention, such as Figure 1 and Figure 7 - Figure 10 As shown, the refrigeration device also includes an airflow conduction device 1 and a storage cover 4. The airflow conduction device 1 is installed on the upper end of the refrigeration tank 2. The storage cover 4 is installed on the top plate 212 of the refrigeration tank 2. A tank vent 213 is opened on the top plate 212. The airflow conduction device 1 is used to accelerate the cold air in the refrigeration tank 2 to the refrigerator 5 through the pipeline 6.

[0042] The airflow conduction device 1 has an internal cavity, and multiple refrigeration vents 114 are provided on the side wall of the airflow conduction device 1. The multiple refrigeration vents 114 are provided one-to-one with the multiple refrigerator boxes 5. The cavity is connected to the refrigeration tank 2 through the tank vent 213, and the cavity is connected to the refrigerator box 5 through the refrigeration vents 114.

[0043] Specifically, such as Figure 10 The airflow conduction device 1 is open at both ends and has a hollow internal structure. A storage cover 4 is installed at the upper end of the airflow conduction device 1, and a refrigeration tank 2 is installed at the lower end. A switching component 3 is installed inside the refrigeration tank 2, and the refrigeration tank 2 is fixedly connected to four refrigerator boxes 5 on its sides. A sliding door is located on the side of each refrigerator box 5; the frozen storage rack is placed inside the refrigerator box 5 by opening the sliding door. The refrigeration tank 2 is connected to an external power source to refrigerate the internal air. Figure 8 The top plate 212 has four tank vents 213 in the middle, and the four tank vents 213 are arranged in a matrix array. The tank vents 213 are connected to the interior of the refrigeration tank 2. The top plate 212 has tank limiting ports 214 at the four corners. The tank limiting ports 214 are connected to the interior of the refrigeration tank 2 and are coaxially arranged with the position of the rotating groove 113 of the airflow conduction device 1.

[0044] In this embodiment, in order to better and quickly deliver the cold air in the refrigeration tank 2 to the refrigerator 5, the airflow conduction device 1 can be activated during refrigeration. Under the action of the airflow conduction device 1, the cold air travels from pipe connection port 1 215 to pipe 6 and then through pipe connection port 2 513 to the refrigerator 5. The air in the refrigerator 5 passes through the refrigeration vent 114 to the cavity of the airflow conduction device 1, and the air in the cavity returns to the refrigeration tank 2 through the tank vent 213.

[0045] In one embodiment of the present invention, such as Figure 10 As shown, the airflow conduction device 1 includes a horizontal fan, which is installed at the upper or lower end of the cavity. The horizontal fan includes a conveying fan 111 and an auxiliary fan 112.

[0046] The conveying fan 111 is located at the upper end of the airflow conduction device 1 cavity and can convey the cold air inside the refrigeration tank 2 downwards; the auxiliary fan 112 is located at the lower end of the airflow conduction device 1 cavity and can convey the cold air inside the refrigeration tank 2 downwards.

[0047] In one embodiment of the present invention, the airflow conduction device 1 includes a vertical fan, and a plurality of the vertical fans are arranged in a one-to-one correspondence with a plurality of the cooling vents 114. The vertical fans are installed at one end of the cooling vents 114 near the cavity. Figure 10As shown, the vertical fan is used to accelerate the delivery of air from the refrigeration vent 114 into the cavity. Multiple fans are added to accelerate the air exchange rate between the refrigeration tank 2 and the refrigerator 5.

[0048] In one embodiment of the present invention, such as Figure 3 As shown, the storage cover 4 includes a cover plate 411 and a limiting frame 413. Multiple limiting frames 413 are installed on the upper surface of the cover plate 411, and multiple telescopic devices 415 are correspondingly installed on multiple limiting frames 413.

[0049] In one embodiment of the present invention, such as Figure 11 and Figure 12 The switching assembly 3 includes a connecting rod 311, a limiting short rod 312, and a blocking part 313. The limiting short rod 312 and the blocking part 313 are installed at the top end of the connecting rod 311. A spring is provided between the top end of the connecting rod 311 and the tank top plate 212. The two ends of the spring are respectively connected to the connecting rod 311 and the tank top plate 212. Figure 8 As shown, the top of the tank top plate 212 is provided with multiple tank limiting ports 214, such as... Figure 9 and Figure 10 As shown, the airflow conduction device 1 has multiple rotating grooves 113. When the telescopic end of the telescopic device 415 extends, it drives the limiting rod 312 to slide within the tank limiting port 214. The blocking part 313 is slidably installed within the tank vent 213. The bottom of the connecting rod 311 is provided with a hollow part 315. The hollow part 315 communicates with the interior of the refrigeration tank 2 through a rod vent 314 provided on the side wall of the hollow part 315. The bottom of the connecting rod 311 is slidably installed within the pipe connection port 215. The rotating groove 113 passes through the refrigeration vent 114, and the diameter of the refrigeration vent 114 is larger than the diameter of the rotating groove 113.

[0050] Specifically, there are four rotating slots 113, located at the four corners of the airflow conduction device 1. The rotating slots 113 vertically penetrate the upper and lower end faces of the airflow conduction device 1. The number of cooling vents 114 corresponds to the number of rotating slots 113. The cooling vents 114 are located on the four corner sidewalls of the airflow conduction device 1, extending laterally into the cavity within the airflow conduction device 1. The cooling vents 114 are connected to the rotating slots 113. A small fan is installed at the end of each cooling vent 114 near the cavity to deliver airflow. The diameter of the cooling vent 114 is larger than the diameter of the rotating slot 113. There are four pipe connection ports 215, located at the four corners of the lower end face of the refrigeration tank 2. The positions of the pipe connection ports 215 are coaxial with the tank limiting port 214, and the pipe connection ports 215 communicate with the interior of the refrigeration tank 2. Figure 1 and Figure 14As shown, the connecting rod 311 is installed inside the refrigeration tank 2. The upper end of the connecting rod 311 has a limiting short rod 312 and a blocking part 313. The limiting short rod 312 and the blocking part 313 are connected by a connecting rod, and a spring (not shown) is installed on the connecting rod between the limiting short rod 312 and the blocking part 313. One end of the spring is connected to the lower end of the tank top plate 212. One end of the blocking part 313 can be inserted into the corresponding tank vent 213, and one end of the limiting short rod 312 can be inserted into the corresponding tank limiting port 214.

[0051] In this embodiment, when the blocking part 313 is inserted into the tank vent 213, the airflow at both ends of the tank top plate 212 cannot flow; when the blocking part 313 is misaligned with the tank vent 213, the airflow at both ends of the tank top plate 212 can flow normally.

[0052] In one embodiment of the present invention, such as Figure 6 As shown, a tank limiting part 216 is installed on the side wall of the refrigeration tank 2, and the connecting rod 311 passes through the tank limiting part 216. The tank limiting part 216 is located at the four corners of the lower end of the interior of the refrigeration tank 2 and is positioned above the pipe connection port 215. A through hole is provided on the tank limiting part 216, and the through hole is coaxially corresponding to the pipe connection port 215.

[0053] In this embodiment, the hollow part 315 is provided with the bottom end of the connecting rod 311. The lower end of the hollow part 315 passes through the hole of the tank limiting part 216, and the bottom end of the hollow part 315 is open. A rod vent 314 is provided around the upper part of the hollow part 315 near the pipe wall, and the rod vent 314 communicates with the interior of the hollow part 315. The lower end of the hollow part 315 is slidably sleeved on the outer wall of one end of the pipe 6, and the hollow part 315 communicates with the pipe 6. The hollow part 315 and the pipe 6 are tightly connected and fitted, and the sliding of the hollow part 315 will not affect the airtightness between the hollow part 315 and the pipe 6.

[0054] In the initial state, the rod vent 314 is blocked by the tank limiting part 216, and the airflow in the hollow part 315 cannot enter the refrigeration tank 2 through the rod vent 314; when the switching component 3 moves down, the rod vent 314 is misaligned with the tank limiting part 216, and the airflow in the hollow part 315 can enter the refrigeration tank 2 through the rod vent 314.

[0055] In one embodiment of the present invention, such as Figure 7 and Figure 8 As shown, a plurality of movable baffles 211 are installed on the top plate 212 of the tank. The movable baffles 211 are arranged around the airflow conduction device 1 to restrict the movement of the airflow conduction device 1. There are four movable baffles 211, which are respectively arranged around the top plate 212 of the refrigeration tank 2.

[0056] In one embodiment of the present invention, a sensing device 512 is installed on the refrigerator 5, which is used to detect the temperature inside the refrigerator 5. When the sensing device 512 detects that the temperature inside the refrigerator 5 is too high, it can control the refrigerator to start working and control the telescopic device 415 to extend, causing the switching component 3 to move down, opening the circulation path between the refrigeration tank 2 and the refrigerator 5, and controlling the fan in the airflow conduction device 1 to work. When the sensing device 512 detects that the temperature is too low or the temperature is within the desired temperature range, it controls the refrigerator to stop working.

[0057] In another embodiment of the present invention, a rotary motor 414 is also installed on the limiting frame 413. The telescopic end of the telescopic device 415 is connected to the telescopic device 415. The telescopic end of the telescopic device 415 drives the rotary motor 414 to move up and down. The output shaft of the rotary motor 414 is inserted into the cover opening 412. When the rotary motor 414 descends, the output shaft of the rotary motor 414 passes through the rotating groove 113 on the airflow conduction device 1 and continues to pass through the tank limiting port 214 on the tank top plate 212 and squeezes the switching assembly 3 to descend. The protrusion on the output shaft of the rotary motor 414 or the long key installed on the output shaft slides in the groove provided in the rotating groove 113.

[0058] The movable baffle 211 is slidably disposed within the through groove of the top plate 212 of the tank. The movable baffle 211 is controlled to move up and down by a cylinder inside the refrigeration tank 2 (the cylinder is not shown). An external remote control can be used to control all four movable baffles 211 to retract into the refrigeration tank 2, or to extend from the top of the refrigeration tank 2 and contact the lower end of the storage cover 4. When the movable baffle 211 extends, as... Figure 5 As shown, the movable baffle 211 surrounds the four walls of the airflow conduction device 1 and can limit the airflow conduction device 1 to a certain extent. The movable baffle 211 is a telescopic plate. When the movable baffle 211 is extended, the two sides of the movable baffle 211 can be extended so that the four movable baffles 211 are connected end to end and form a closed space with the tank top plate 212 and the storage cover 4.

[0059] The cover plate 411 is located on the upper end of the airflow conduction device 1. The cover plate 411 has a cover opening 412 at each of its four corners, and the cover opening 412 passes through the upper and lower end faces of the cover plate 411. The limiting frame 413 is located on the upper end of the cover plate 411 and is correspondingly located above the cover opening 412. The upper end of the limiting frame 413 is in contact with and fixed to the telescopic device 415. The rotating motor 414 is located at the lower end of the telescopic device 415. The rotating motor 414 has a protruding clip (not shown) on its rotating shaft. When the rotating motor 414 rotates, the protruding clip can engage with the slot of the rotating groove 113, thereby driving the airflow conduction device 1 to rotate.

[0060] like Figure 3The slot of the limiting bracket 413 is coaxially aligned with the cover opening 412, facilitating the downward movement of the rotating motor 414 driven by the telescopic device 415. The motor 414 then contacts and presses against the lower limiting rod 312 through the cover opening 412, thereby controlling the downward movement of the switching component 3. All four rotating motors 414 and four telescopic devices 415 are independently controlled. When the airflow conduction device 1 needs to be rotated into one of the refrigerator compartments 5, one of the telescopic devices 415 drives the rotating motor 414 downward, controlling the lower end of the rotating motor 414 to contact and lock with the rotating groove 113 of the airflow conduction device 1. This causes the rotating motor 414 to drive the airflow conduction device 1 to rotate 180 degrees around its axis, thus entering the refrigerator compartment 5 diagonally opposite the rotating motor 414. During this operation, the other three rotating motors 414 and three telescopic devices 415 are not operational.

[0061] like Figure 4 and Figure 13 The refrigerator 5 includes: a refrigerator panel 511, a sensing device 512, a sealing baffle 514, and a rotating hole 515. The sealing baffle 514 is rotatably disposed at the opening 5112 of the refrigerator panel 511; the sealing baffle 514 is divided into upper and lower sealing baffles 514, and the sides of the two sealing baffles 514 that are close to each other are magnetic. The two sealing baffles 514 are magnetically attracted to each other, and can seal the refrigerator 5 under normal conditions. The two sealing baffles 514 are respectively disposed at the upper and lower ends of the opening 5112 via a rotating shaft.

[0062] The rotating hole 515 is located at the upper and lower ends of the opening of the refrigerator 5, and at one end away from the corner joint of the refrigerator 5. The rotating shaft of the sealing baffle 514 is rotatably connected to the rotating hole 515 through a live bearing.

[0063] When the airflow conduction device 1 needs to enter the refrigerator 5, the rotating motor 414 drives the airflow conduction device 1 to rotate. The side of the airflow conduction device 1 will contact and press against the outer surface of the sealing baffle 514, causing the upper and lower sealing baffles 514 to open in the direction of the movement of the airflow conduction device 1 until the sealing baffles 514 rotate to a horizontal state. At this time, the airflow conduction device 1 is not blocked, so that the airflow conduction device 1 continues to enter the refrigerator 5 to be cooled. When the airflow conduction device 1 is completely inside the refrigerator 5, the upper and lower sealing baffles 514 are magnetically attracted back together, sealing the refrigerator 5. Similarly, when the airflow conduction device 1 needs to rotate out of the refrigerator 5, the upper and lower sealing baffles 514 are opened. After the airflow conduction device 1 is completely out of the refrigerator 5, the upper and lower sealing baffles 514 are magnetically attracted back together, sealing the refrigerator 5. If the airflow conduction device 1 is located below the cover plate 411, even if the pipe connection ports 215 corresponding to the other three refrigerators 5 are blocked, due to the action of the airflow conduction device 1, in the initial stage, some air in the other three refrigerators 5 will be drawn into the refrigeration tank 2 through the refrigeration vent 114, reducing the refrigeration efficiency. When the airflow conduction device 1 is transferred to one refrigerator 5, the airflow conduction device 1 directly blows the sample placed in the refrigerator 5, which accelerates the cooling rate of the sample. In addition, the airflow conduction device 1 increases the air circulation speed in the refrigerator 5, drawing most of the cold air from the refrigeration tank 2 into the refrigerator 5.

[0064] Furthermore, a groove (not shown) is provided around the bottom edge of the cover plate 411, and the groove corresponds to the position of the movable baffle 211, so that the movable baffle 211 can be inserted into the groove when it is extended, so as to further enhance the sealing of the subsequent refrigerator 5.

[0065] Furthermore, a control device (not shown) is provided on the storage cover 4. The control device is used to control the operation of power devices such as the telescopic device 415 and the rotating motor 414. The sensing device 512 can transmit the sensed signal to the control device, and the control device further controls the power devices such as the telescopic device 415 and the rotating motor 414 according to the received signal.

[0066] Working principle of the invention:

[0067] Initial state as Figure 1 As shown, the four telescopic devices 415 are in the retracted state, the lower ends of the four rotating motors 414 are not in contact with the rotating groove 113 of the airflow conduction device 1, and the blocking parts 313 of the four switching components 3 are inserted into the tank vent 213 to block the tank vent 213; the rod vent 314 of the switching component 3 is in contact with the tank limiting part 216, and the rod vent 314 is blocked. Therefore, at this time, the refrigeration tank 2 is not connected to each refrigerator 5, and the refrigeration tank 2 does not refrigerate any refrigerator 5.

[0068] Next, the four refrigerators 5 are cooled. First, the entire system is powered on, and the required cooling temperature range is preset on the sensing devices 512 at the top of the refrigerators 5. When the temperature inside the four refrigerators 5 does not reach the cooling temperature range, the four sensing devices 512 convert the temperature sensing signal into an electrical signal and feed it back to the corresponding telescopic device 415. This controls the four telescopic devices 415 to drive the rotating motor 414 downwards, contacting and pressing against the upper limit rod 312 of the switching assembly 3. This ultimately causes the switching assembly 3 to move downwards a certain distance. At this point, the blocking parts 313 of the four switching assemblies 3 disengage from the tank vent 213, and the blocking parts 313 no longer obstruct the tank vent 213. The lower rod vent 314 moves downwards and disengages from the tank limit part 216 of the refrigeration tank 2, and the tank limit part 216 no longer obstructs the rod vent 314. Then, the conveying fan 111 drives the cold airflow inside the refrigeration tank 2 downwards, and the cold airflow flows along the rod vent 314. The air enters the pipe 6 and then finally enters the four refrigerator boxes 5. The uncooled airflow inside the refrigerator box 5 moves upward and enters the lower end of the airflow conduction device 1 through the refrigeration vent 114. Under the control of the conveying fan 111 and the auxiliary fan 112, it will enter the refrigeration tank 2 again through the tank vent 213 and cool the uncooled gas. When the refrigeration temperature reaches the refrigeration range, the four sensing devices 512 will send a signal to the four telescopic devices 415 and control the telescopic devices 415 to drive the rotating motor 414 to retract to the upper end. The four switching components 3 will also retract to the upper end under the tension of the spring, so that the blocking part 313 contacts the tank vent 213 again and the rod vent 314 contacts the tank limit part 216 again. At this time, the airflow in the four refrigerator boxes 5 and the refrigeration tank 2 is no longer flowing. At the same time, the conveying fan 111 and the auxiliary fan 112 stop working. At this time, the synchronous refrigeration cycle of the four refrigerator boxes 5 is completed.

[0069] When the temperature inside a single refrigerator compartment 5 does not reach the refrigeration temperature range, the sensing device 512 converts the temperature sensing signal into an electrical signal and feeds it back to the telescopic device 415 corresponding to that refrigerator compartment 5. This telescopic device 415 then drives the rotating motor 414 downwards, contacting and pressing against the upper limit rod 312 of the corresponding switching component 3. This causes the switching component 3 to move downwards a certain distance. The positional relationship between the switching component 3 and the interior of the refrigeration tank 2 is the same as that of the four refrigerator compartments 5 in the synchronous refrigeration process, which is omitted here. At this time, all moving baffles 211 retract and enter the side wall of the refrigeration tank 2 via external remote control. Next, the rotating motor 414 drives the airflow conduction device 1 to rotate 180 degrees around the center of the rotating motor 414 and enter the refrigerator compartment 5. During the rotation of the airflow conduction device 1 by the rotating motor 414, the outer wall of the airflow conduction device 1 will seal against the refrigerator compartment 5. The sealing baffle 514 is squeezed, and finally the airflow conduction device 1 passes through the sealing baffle 514 and enters the refrigerator 5 to be cooled. During rotation, the airflow conduction device 1 is first squeezed by the sealing baffles 514 of other refrigerators 5, and then rotates to the outer surface of the sealing baffle 514 of the refrigerator 5 to be cooled. The upper and lower sealing baffles 514, under pressure, rotate towards the interior of the refrigerator 5 to be cooled until they are horizontal, allowing the airflow conduction device 1 to enter the refrigerator 5 under the control of the rotating motor 414. After the airflow conduction device 1 is fully inside the refrigerator 5, it no longer contacts and squeezes the sealing baffle 514. The sealing baffles 514 are magnetically attracted together again, sealing the refrigerator 5. Then, the remotely controlled movable baffle 211 extends from the side wall of the refrigeration tank 2 to seal the refrigeration tank 2 and the refrigerator 5. Figure 14 As shown, the airflow channel of a single refrigerated container 5 requiring cooling is connected to that of the refrigeration tank 2. Under the control of the conveying fan 111 and the auxiliary fan 112, the airflow moves as follows: Figure 14 As shown, uncooled air in the refrigerator 5 enters the refrigeration tank 2 through the pipe 6 and the rod vent 314. The cold air inside the refrigeration tank 2 enters the airflow conduction device 1 through the tank vent 213 and the refrigeration vent 114. Then, the cold airflow is controlled by the conveying fan 111 and the auxiliary fan 112 to fill the refrigerator 5 to be cooled downwards, thus achieving full cooling of a single refrigerator 5.

[0070] When the refrigeration temperature of the refrigerator 5 reaches the refrigeration range, the conveying fan 111 and the auxiliary fan 112 stop working, and the remote control moves the baffle 211 to retract into the side wall of the refrigeration tank 2. The control motor 414 drives the airflow conduction device 1 to rotate 180 degrees, pass through the sealing baffle 514, and return to the top of the refrigeration tank 2. Then the control moves the baffle 211 to extend out from the side wall of the refrigeration tank 2. At this time, the reset of the airflow conduction device 1 is completed.

[0071] The device of the present invention achieves refrigeration of multiple refrigerator boxes 5 or centralized refrigeration of a single refrigerator box 5 by changing the position of the airflow conduction device 1.

[0072] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
