Description

Technical Field

[0001] This invention relates to the field of food testing, specifically to an energy-saving food sample storage and refrigeration system for food testing. Background Technology

[0002] In the field of sample testing, especially in the process of food sample testing, in order to ensure the validity of the samples and extend their storage time, a refrigeration unit is used to cool the sample storage device and preserve the biological samples.

[0003] However, traditional refrigeration machines use cold air to exchange heat and cold through copper pipes to treat items placed inside the refrigeration machine at low temperatures to extend their shelf life. However, the intermittent refrigeration method using temperature interaction modules such as copper pipes reduces the efficiency of the refrigeration machine, thereby increasing its energy consumption and making it difficult to meet the energy conservation and emission reduction requirements of current enterprise development.

[0004] Some directly cooling devices, however, lack proper airflow control because their ducts and vents are located within the storage unit. This reduces the efficiency of the cooling air distribution within the storage unit, prolonging the cooling time and thus increasing the equipment's internal friction.

[0005] In response, we propose an energy-saving food sample storage refrigeration system for food testing to reduce the energy consumption of refrigeration equipment and thus improve its energy-saving effect. Summary of the Invention

[0019] The downward pressure relief mechanism includes a first cover plate disposed on the guide plate, a first piston slidably disposed inside the guide plate, and a limit block disposed inside the guide plate, wherein the limit block is adapted to the first piston.

[0020] As an optional solution of the energy-saving food sample storage and refrigeration system for food inspection described in this invention, wherein: a first central guide rod is further provided on the first cover plate, and the first piston is slidably disposed on the first central guide rod;

[0021] A sealing plate is also provided on the first central guide rod, and a strong spring is also provided on the first piston. The first piston is also elastically connected to the first cover plate through the strong spring.

[0022] As an optional solution of the energy-saving food sample storage and refrigeration system for food inspection described in this invention, wherein: the guide plate is further provided with an upward pressure relief mechanism, which is used to reduce resistance when the guide plate is reset;

[0023] The upward pressure relief mechanism includes a second cover plate disposed on the assembly mechanism. The assembly mechanism is also provided with a bottom limiting plate, and the second cover plate and the bottom limiting plate are adapted to each other.

A water storage tank is also provided in the bottom plate, and the copper column and the water storage tank are interconnected.

[0027] As an optional solution of the energy-saving food sample storage and refrigeration system for food inspection described in this invention, the copper column is provided with a reinforcing mechanism, the reinforcing mechanism includes a branch channel opened on the copper column, and a main channel is also opened in the copper column, and the branch channel and the main channel are interconnected.

[0028] As an optional solution of the energy-saving food sample storage and refrigeration system for food inspection described in this invention, wherein: a collection mechanism is provided at the bottom of the copper column, and the collection mechanism is used to collect condensate;

[0029] The collection mechanism includes a connecting pipe disposed at the bottom of the copper column, a collector disposed on the connecting pipe, a guide pipe disposed on the collector, one end of the guide pipe being connected to the collector, and the other end of the guide pipe being connected to the water storage tank.

[0030] The water storage tank is also equipped with a drain pipe, and the water storage tank is connected to the refrigeration unit through the drain pipe.

[0031] The present invention has the following beneficial effects:

[0032] 1. This energy-saving food sample storage refrigeration system for food inspection incorporates a mezzanine within the storage cabinet to reduce energy consumption of the refrigeration unit. An input pipe from the refrigeration unit is inserted into this mezzanine, allowing cold air generated by the refrigeration unit to be directly delivered to the storage cabinet through the mezzanine. The output pipe then guides the gas from the mezzanine back into the refrigeration unit for re-cooling and delivery, completing the required cold air delivery cycle. Since cold air is heavier than hot air, the connection port between the input pipe and the storage cabinet is located on the side wall near the top of the storage cabinet, while the connection port between the output pipe and the storage cabinet is located on the side wall near the bottom of the storage cabinet. The input and output pipes are positioned on opposite side walls of the storage cabinet to prevent premature interaction between hot and cold air, which could affect the normal refrigeration effect.

[0033] 2. In order to further improve the intensity of direct cooling, the energy-saving food sample storage and refrigeration system for food inspection also has an airflow channel in the storage cabinet, and the airflow channel is directly connected to the interlayer. The airflow channel is located on the inner wall at the top of the storage cabinet, so as to facilitate the natural sinking of cold air from the top to the bottom of the storage cabinet, thereby directly cooling the samples placed in the storage cabinet.

[0034] To increase the flow rate of cold air and guide its direction to improve the flow rate of cold air from the airflow channel into the storage cabinet, a fixed base is installed on the storage cabinet within the interlayer. A rotating shaft is mounted on the fixed base, and a pressurized fan blade is mounted on the rotating shaft. The pressurized fan blade is located within the airflow channel. An external motor drives the rotating shaft to rotate the pressurized fan blade within the airflow channel, thereby pressurizing and delivering the cold air flowing within the interlayer into the storage cabinet, thus improving the cooling effect.

[0035] 3. In order to further cooperate with the pressurized fan blades to guide the cold air in the interlayer and improve the pressurization effect, the energy-saving food sample storage refrigeration system for food inspection has a guide plate slidably installed on the fixed base, and a drive device is also installed on the fixed base. The drive device can drive the guide plate to make up-and-down reciprocating cyclical movements on the fixed base, thereby continuously guiding and transporting the cold air in the interlayer towards the pressurized fan blades, so as to ensure that the pressurized fan blades can deliver a sufficient amount of cold air to cool the items in the storage cabinet.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1, please refer to Figure 1-10 A cooling system for storing food samples for food inspection is disclosed, including a storage cabinet 1, a refrigeration unit 2 at the bottom of the storage cabinet 1, the refrigeration unit 2 being used to cool the storage cabinet 1, and an assembly mechanism at the bottom of the storage cabinet 1, with both the storage cabinet 1 and the refrigeration unit 2 mounted on the assembly mechanism.

[0049] The assembly mechanism includes a base plate 31 set on the ground, a refrigeration unit 2 set on the base plate 31, a partition 32 on the top of the refrigeration unit 2 that is compatible with the base plate 31, and a storage cabinet 1 set on the partition 32. The base plate 31 and the partition 32 are compatible with each other.

[0050] The refrigeration unit 2 is also equipped with an input pipe 41, which connects the refrigeration unit 2 to the storage cabinet 1. The storage cabinet 1 is equipped with an output pipe 42, which connects the storage cabinet 1 to the refrigeration unit 2.

[0051] The storage cabinet 1 has a mezzanine 5, and both the input pipe 41 and the output pipe 42 are connected to the mezzanine 5.

[0052] In this embodiment: Traditional refrigeration machines use cold air to exchange hot and cold temperatures through copper pipes to treat items placed inside the refrigeration machine at low temperatures to extend their shelf life. However, the intermittent refrigeration method using temperature interaction modules such as copper pipes reduces the efficiency of the refrigeration machine, thereby increasing its energy consumption and making it difficult to meet the energy conservation and emission reduction requirements of current enterprise development.

[0053] Therefore, in order to reduce the energy consumption of the refrigeration unit, a mezzanine 5 is installed inside the storage cabinet 1. The input pipe 41 installed on the refrigeration unit 2 is inserted into the mezzanine 5, so that the cold air generated by the refrigeration unit 2 can be directly transported to the storage cabinet 1 through the mezzanine 5. Then, the gas in the mezzanine 5 is discharged into the refrigeration unit 2 through the output pipe 42, and then cooled and transported again to complete the cold air transport cycle required for refrigeration.

[0054] Meanwhile, since cold air is heavier and hot air is lighter, the connection port between the input pipe 41 and the storage cabinet 1 is located on the side wall near the top of the storage cabinet 1, and the connection port between the output pipe 42 and the storage cabinet 1 is located on the side wall near the bottom of the storage cabinet 1. The input pipe 41 and the output pipe 42 are respectively located on the two side walls of the storage cabinet 1 to prevent the cold and hot air from interacting prematurely and affecting the normal cooling effect.

[0055] This bypasses the copper pipe temperature interaction link in traditional refrigeration equipment, changing from traditional indirect refrigeration to direct refrigeration, thereby improving refrigeration efficiency, shortening refrigeration time, and thus achieving the goal of reducing energy consumption.

[0056] Example 2, please refer to Figure 1-10Inside the storage cabinet 1, there is also a rotating pressurized fan blade 6, which is used to guide the cold air in the interlayer 5 into the storage cabinet 1.

[0057] A fixed base 7 is installed on the storage cabinet 1, and a rotating shaft 12 is rotatably mounted on the fixed base 7. The pressure fan blade 6 is mounted on the rotating shaft 12.

[0058] A guide plate 13 is also slidably mounted on the fixed base 7. The guide plate 13 is used to deliver cold air towards the direction close to the pressurized fan blade 6.

[0059] The fixed base 7 is also equipped with a driving device, which is used to drive the guide plate 13 to slide up and down reciprocally within the interlayer 5.

[0060] The driving device includes an abutment rod 141 slidably mounted on a fixed base 7, and an abutment block 143 mounted on a rotating shaft 12, with the abutment block 143 intermittently abutting the abutment rod 141;

[0061] The fixed base 7 is also provided with a guide rod 142, and the abutment rod 141 is slidably disposed on the guide rod 142;

[0062] A return spring 15 is also provided on the guide rod 142, and the guide rod 142 is also elastically connected to the abutment rod 141 through the return spring 15.

[0063] In this embodiment: In order to further improve the intensity of direct cooling, an airflow channel is also provided in the storage cabinet 1, and the airflow channel is directly connected to the interlayer 5. The airflow channel is located on the inner wall at the top of the storage cabinet 1, so as to facilitate the natural sinking of cold air from the top of the storage cabinet 1 to the bottom of the storage cabinet 1, thereby directly cooling the sample placed in the storage cabinet 1.

[0064] To increase the flow rate of cold air and guide its direction to improve the flow rate of cold air from the airflow channel into the storage cabinet 1, a fixed base 7 is provided on the storage cabinet 1. The fixed base 7 is located in the interlayer 5. A rotating shaft 12 is rotatably mounted on the fixed base 7, and a pressurizing fan blade 6 is mounted on the rotating shaft 12. The pressurizing fan blade 6 is located in the airflow channel. An external motor drives the rotating shaft 12 to rotate the pressurizing fan blade 6 in the airflow channel, thereby pressurizing and delivering the cold air flowing in the interlayer 5 into the storage cabinet 1, thereby improving the cooling effect.

[0065] Additional explanation: The design of the pressurized fan blade 6 is that of a turbine fan blade. Its pressurization principle is the same as that of the turbine fan blade rotation pressurization, so it will not be described in detail again.

[0066] To further coordinate with the pressurizing fan blades 6 to guide the cold air in the interlayer 5 and improve the pressurization effect, a guide plate 13 is slidably installed on the fixed base 7, and a driving device is also installed on the fixed base 7. The driving device can drive the guide plate 13 to make up-and-down reciprocating cyclical movements on the fixed base 7, thereby continuously guiding and transporting the cold air in the interlayer 5 toward the pressurizing fan blades 6, so as to ensure that the pressurizing fan blades 6 can deliver a sufficient amount of cold air to cool the items in the storage cabinet 1.

[0067] The driving device includes an abutment rod 141 slidably mounted on a fixed base 7, an abutment block 143 mounted on a rotating shaft 12, and the abutment block 143 intermittently abutting the abutment rod 141. A guide rod 142 is also provided on the fixed base 7, the abutment rod 141 is slidably mounted on the guide rod 142, and a return spring 15 is also provided on the guide rod 142. The guide rod 142 is also elastically connected to the abutment rod 141 through the return spring 15.

[0068] When the rotating shaft 12 is driven by an external motor to rotate on the fixed base 7, the abutment block 143 provided on the rotating shaft 12 will abut against the abutment rod 141 slidably provided on the fixed base 7, thereby causing the abutment rod 141 to slide on the guide rod 142 in the direction closer to the fixed base 7. This causes the guide plate 13 provided on the abutment rod 141 to slide towards the fixed base 7, thereby pressing down the flowing cold air to complete the flow of cold air and improve the efficiency of the pressurized fan blade 6.

[0069] Since the contact block 143 is mounted on the rotating shaft 12, and the rotating shaft 12 rotates continuously under the drive of an external motor, the contact block 143 will also continuously perform circular motion around the rotating shaft 12 as the central axis within the interlayer 5, thereby intermittently contacting the contact rod 141. In order to facilitate the direct contact operation between the contact block 143 and the guide rod 142, an inclined surface is provided on the contact block 143, and the inclination angle gradually increases from one side of the contact block 143 to the other side, thereby preventing the contact block 143 from directly jamming when it comes into direct contact with the contact rod 141.

[0070] To facilitate the reset of the abutment rod 141 when it is not in contact with the abutment block 143, a reset spring 15 is provided on the guide rod 142. The guide rod 142 is directly and elastically connected to the abutment rod 141 through the reset spring 15. When the abutment rod 141 slides towards the fixed seat 7, it will compress the reset spring 15, causing it to undergo elastic deformation and generate elastic potential energy. When the abutment rod 141 and the abutment block 143 move away from each other, the reset spring 15 loses the resistance of the abutment block 143, thereby releasing its accumulated elastic potential energy and generating a reverse thrust. This allows the abutment rod 141 to reset and slide towards the top of the storage cabinet 1 to wait for direct contact with the abutment block 143 again, thus completing the reciprocating cycle operation.

[0071] Example 3, please refer to Figure 1-10 The guide plate 13 is also equipped with a downward pressure relief mechanism, which is used to prevent jamming between the contact rod 141 and the contact block 143.

[0072] The downward pressure relief mechanism includes a first cover plate 161 disposed on the guide plate 13, a first piston 162 slidably disposed inside the guide plate 13, and a limit block 163 disposed inside the guide plate 13, and the limit block 163 is adapted to the first piston 162.

[0073] A first central guide rod 17 is also provided on the first cover plate 161, and the first piston 162 is slidably disposed on the first central guide rod 17.

[0074] A sealing plate 19 is also provided on the first central guide rod 17, and a strong spring 18 is also provided on the first piston 162. The first piston 162 is also elastically connected to the first cover plate 161 through the strong spring 18.

[0075] In this embodiment: In order to prevent excessive resistance from the wind resistance generated by the cold air flow during the downward sliding of the guide plate 13, and to avoid the reduced flow guiding effect of the guide plate 13 in the open state, a downward pressure relief mechanism is also provided in the pressure relief hole on the guide plate 13. The downward pressure relief mechanism performs pressure relief work on the guide plate 13 when it slides downward, thereby preventing jamming between the contact rod 141 and the contact block 143, which would affect the rotation of the pressurized fan blade 6.

[0076] The downward pressure relief mechanism includes a first cover plate 161 mounted on a guide plate 13, a first piston 162 slidably mounted inside the guide plate 13, a limit block 163 mounted inside the guide plate 13 and adapted to the first piston 162, a first central guide rod 17 mounted on the first cover plate 161, the first piston 162 slidably mounted on the first central guide rod 17, a sealing plate 19 mounted on the first central guide rod 17, and a strong spring 18 mounted on the first piston 162. The first piston 162 is also elastically connected to the first cover plate 161 through the strong spring 18.

[0077] When the guide plate 13 slides towards the fixed base 7, the gas flow direction is from the bottom of the guide plate 13 to the top of the guide plate 13 to pressurize it. At this time, if the gas pressure reaches a certain value, the first piston 162 will separate from the limiting block 163 under the action of the gas pressure and slide towards the first cover plate 161, so that the pressure relief hole is open and the gas can flow out from the pressure relief hole, thereby reducing the wind resistance received by the guide plate 13 and thus preventing the contact rod 141 and the contact block 143 from getting stuck.

[0078] In order to ensure that the first piston 162 is only pushed by the gas after it has encountered a certain resistance, a downward pressure relief mechanism is provided between the first piston 162 and the first cover plate 161. The first piston 162 is elastically connected to the first cover plate 161 through a strong spring 18, so that the strong spring 18 applies resistance to the first piston 162 relative to the wind resistance, thereby preventing the first piston 162 from opening easily during the downward movement of the guide plate 13.

[0079] Example 4, please refer to Figure 1-10 The guide plate 13 is also equipped with an upward pressure relief mechanism, which is used to reduce resistance when the guide plate 13 is reset.

[0080] The upward pressure relief mechanism includes a second cover plate 201 disposed on the assembly mechanism, and a bottom limiting plate 202 disposed on the assembly mechanism. The second cover plate 201 and the bottom limiting plate 202 are adapted to each other. A second piston 203 is also slidably disposed inside the assembly mechanism, and the second piston 203 abuts against the second cover plate 201.

[0081] The bottom limiting plate 202 is also provided with a second central guide rod 21, and the second piston 203 is slidably disposed in the assembly mechanism through the second central guide rod 21;

[0082] The second piston 203 is also elastically connected to the bottom limiting plate 202 via a weak spring 22.

[0083] In this embodiment: as above, in order to reduce the resistance received by the guide plate 13 when it moves towards the top of the storage cabinet 1 and to prevent the guide plate 13 from failing to reset, an upward pressure relief mechanism is also provided on the guide plate 13.

[0084] The upward pressure relief mechanism includes a second cover plate 201 installed on the assembly mechanism. The assembly mechanism is also provided with a bottom limiting plate 202, and the second cover plate 201 and the bottom limiting plate 202 are adapted to each other. A second piston 203 is also slidably installed inside the assembly mechanism. The second piston 203 abuts against the second cover plate 201. A second central guide rod 21 is also provided on the bottom limiting plate 202. The second piston 203 is slidably installed inside the assembly mechanism through the second central guide rod 21.

[0085] The second piston 203 is also elastically connected to the bottom limiting plate 202 via a weak spring 22.

[0086] When the guide plate 13 moves toward the top of the storage cabinet 1, the air pressure is applied from the top to the bottom of the guide plate 13. Therefore, when the pressure received by the guide plate 13 is large, the second piston 203 will slide inside the guide plate 13, thereby moving away from the second cover plate 201. This allows the second cover plate 201 and the bottom limiting plate 202 to cooperate with each other, so that the cold air can pass through the bottom limiting plate 202 and the second cover plate 201 and penetrate the guide plate 13, thereby reducing the resistance it receives.

[0087] Example 5, please refer to Figure 1-10 The storage cabinet 1 is also equipped with a copper column 8, with one end of the copper column 8 located inside the storage cabinet 1 and the other end located inside the interlayer 5. A water storage tank 10 is also provided in the bottom plate 31, and the copper column 8 and the water storage tank 10 are interconnected.

[0088] The copper column 8 is equipped with a reinforcing mechanism, which includes a branch channel 231 opened on the copper column 8. The copper column 8 is also equipped with a main channel 232, and the branch channel 231 and the main channel 232 are interconnected.

[0089] In this embodiment: In order to improve the cooling rate at the bottom of the storage cabinet 1, a plurality of copper pillars 8 are provided at the bottom of the storage cabinet 1, with one side of the copper pillar 8 located inside the storage cabinet 1 and the other side located inside the interlayer 5. This allows the ambient temperature gas at the bottom of the storage cabinet 1 to exchange heat with the cold air in the interlayer 5 through the copper pillars 8, thereby further accelerating the cooling rate inside the storage cabinet 1.

[0090] To increase the heat dissipation area of ​​the copper column 8, a reinforcing mechanism is provided inside the copper column 8. This mechanism includes multiple branch channels 231 formed on the copper column 8, and a main flow channel 232 is also formed inside the copper column 8. The multiple branch channels 231 are all connected to the main flow channel 232. Through the branch channels 231, multiple holes are formed inside the copper column 8 to increase the contact area between the copper column 8 and the room temperature gas, thereby improving the heat conduction effect of the copper column 8. By setting the main flow channel 232 and connecting the branch channels 231 to the main flow channel 232, the room temperature gas can be collected inside the copper column 8 and cooled in a concentrated manner.

[0091] Example 6, please refer to Figure 1-10 A collection mechanism is provided at the bottom of the copper column 8 to collect condensate.

[0092] The collection mechanism includes a connecting pipe 241 set at the bottom of the copper column 8, a collector 242 set on the connecting pipe 241, a guide pipe 9 set on the collector 242, one end of the guide pipe 9 is connected to the collector 242, and the other end of the guide pipe 9 is connected to the water storage tank 10.

[0093] The drainage pipe 11 is connected to the refrigeration unit 2.

[0094] In this embodiment: when room temperature gas and cold air exchange heat inside the copper column 8, a certain amount of condensate will be generated. In order to collect and process the condensate, a collection mechanism is provided at the bottom of the copper column 8. The collection mechanism includes a connecting pipe 241 provided at the bottom of the copper column 8, a collector 242 provided on the connecting pipe 241, a guide pipe 9 provided on the collector 242, and one end of the guide pipe 9 is connected to the collector 242, and the other end of the guide pipe 9 is connected to the water storage tank 10.

[0095] The connecting pipe 241 is also connected to the main flow channel 232, so that the condensate in the main flow channel 232 will flow through the connecting pipe 241 to the collector 242, and finally flow through the guide pipe 9 to the water tank 10 opened in the partition 32.

[0096] Furthermore, a drain pipe 11 is provided on the partition 32, through which the condensate in the water storage tank 10 can flow to the refrigerator 2 for recooling.

Start the refrigeration unit 2, so that the cold air generated by the refrigeration unit 2 is delivered to the top of the storage cabinet 1 through the input pipe 41, and the original room temperature gas in the storage cabinet 1 is delivered to the refrigeration unit 2 through the output pipe 42 for refrigeration.

[0099] S2. The external motor drives the rotating shaft 12 to rotate the pressurized fan blades 6 in the airflow channel, thereby pressurizing and delivering the cold air flowing in the interlayer 5 into the storage cabinet 1.

[0100] S3. When the rotating shaft 12 is in motion, it will synchronously drive the guide plate 13 to make up-down reciprocating cyclical movements on the fixed seat 7, thereby continuously guiding and transporting the cold air in the interlayer 5 toward the pressurized fan blade 6.

[0101] S4. Multiple copper pillars 8 are also provided at the bottom of the storage cabinet 1. One side of the copper pillar 8 is set inside the storage cabinet 1, and the other side is set inside the interlayer 5. This allows the ambient temperature gas at the bottom of the storage cabinet 1 to exchange heat with the cold air in the interlayer 5 through the copper pillars 8, thereby further accelerating the cooling rate inside the storage cabinet 1.

[0102] S5. When room temperature gas and cold air exchange heat inside the copper column 8, a certain amount of condensate will be generated. In order to collect and treat the condensate, a collection mechanism is provided at the bottom of the copper column 8. The collection mechanism includes a connecting pipe 241 at the bottom of the copper column 8, a collector 242 on the connecting pipe 241, a guide pipe 9 on the collector 242, one end of the guide pipe 9 is connected to the collector 242, and the other end of the guide pipe 9 is connected to the water storage tank 10.

[0103] The connecting pipe 241 is also connected to the main flow channel 232, so that the condensate in the main flow channel 232 will flow through the connecting pipe 241 to the collector 242, and finally flow through the guide pipe 9 to the water tank 10 opened in the partition 32.

[0104] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0105] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
