DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0030] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] An embodiment of the present application provides a multifunctional integrated food storage device that integrates fresh-keeping, freezing, and thawing, including a fresh-keeping chamber 1, a freezing chamber 2, and a thawing chamber 3, and also includes a circulation component, which includes a main track 4, a plurality of sub-tracks 5, a steering component 6, and a circulation vehicle 7. The plurality of sub-tracks 5 are respectively docked with the fresh-keeping chamber 1, the freezing chamber 2, and the thawing chamber 3. The steering component 6 includes a steering seat and a steering platform 12. The steering seat is arranged at the end of the main track 4. The turning platform 12 is rotatably connected to the steering seat. The turning platform 12 is provided with a steering track 13. The head ends of the plurality of sub-tracks 5 are arranged around the circumference of the turning platform 12. The circulation vehicle 7 is movably arranged on the main track 4.

[0032] Fresh-keeping compartment 1 is used to preserve and store food. It can utilize negative ion ice-temperature preservation technology, a technique well known to those skilled in the art. Its principles and the equipment required for implementation are well known to those skilled in the art and will not be elaborated upon here. In summary, negative ion ice-temperature preservation technology combines temperature control with negative ion sterilization. Refrigeration equipment stabilizes the food temperature within an appropriate range, extending its storage life. Negative ions are then generated by a negative ion generator, which electrically neutralizes bacterial surface proteins, achieving the sterilization effect.

[0033] Freezing chamber 2 is used for frozen storage of food. Freezing chamber 2 can adopt low-temperature electric field quick-freezing technology. Low-temperature electric field quick-freezing technology is a technology well known to those skilled in the art. Its principles, equipment required for implementation, etc. are well known to those skilled in the art and will not be repeated here. In summary, low-temperature electric field quick-freezing technology is to apply an electric field of specific frequency and intensity to food during the quick-freezing process of food, and change the arrangement of water molecules through the electric field force, so as to prompt the water to form smaller and more uniform ice crystals when freezing. This electric field intervention can reduce the mechanical damage of large ice crystals to the cell structure of food, thereby retaining more nutrients and taste. In an extremely low temperature environment (such as below -18°C), the electric field and cold air work together to effectively shorten the time it takes for the center temperature of the food to reach the freezing point.

[0034] Thawing chamber 3 is used to thaw frozen food. Thawing chamber 3 can utilize electric field thawing technology, which is well known to those skilled in the art. Its principles and the equipment required for implementation are well known to those skilled in the art and will not be further described here. In summary, electric field thawing technology applies a high-voltage electrostatic field to the food during the thawing process. Because water molecules form a dynamic equilibrium, quasi-stable cluster structure through hydrogen bonds, the micro-energy effect of the high-voltage electrostatic field can disrupt this equilibrium, causing the hydrogen bond breakage rate to exceed the recombination rate, resulting in the disintegration of the ice crystal structure into smaller secondary ice crystals, thereby shortening the thawing time.

[0035] The main track 4 and the sub-track 5 are used for the movement of the circulation vehicle 7 along the set track. The main track 4 can be used to input and output food into different chambers. The main track 4 can also be used to temporarily store the circulation vehicle 7. For example, when multiple circulation vehicles 7 are arranged on the track, in order to avoid collisions between circulation vehicles 7 moving on the same track, the circulation vehicle 7 can be stopped on the main track 4 as needed to avoid collisions between circulation vehicles 7.

[0036] The circulation vehicle 7 is used to transport food.

[0037] Since the turning platform 12 is rotatably disposed at the end of the main track 4, different tracks can be docked through the turning component 6, for example, the main track 4 can be docked with different sub-tracks 5, or two different sub-tracks 5 can be docked, thereby allowing the circulation vehicle 7 to travel along different paths. Taking the circulation vehicle 7 starting to move from the main track 4 as an example, the turning platform 12 is first rotated so that the steering track 13 is docked with the main track 4. At this time, the circulation vehicle 7 can move from the main track 4 along the steering track 13 to the turning platform 12. Then the turning platform 12 continues to rotate so that the steering track 13 can be docked with the desired sub-track 5, so that the circulation vehicle 7 can move from the steering track 13 to the sub-track 5, so that the circulation vehicle 7 can travel along the sub-track 5.

[0038] Due to the complexity of production activities, in the actual production process, it is often encountered that multiple foods need to be transported to different chambers separately, or that foods need to flow between different chambers.

[0039] When the turning platform 12 rotates, the turning track 13 on the turning platform 12 can dock with different tracks, so that different tracks can be docked through the turning component 6, for example, the main track 4 can be docked with different sub-tracks 5, or two different sub-tracks 5 can be docked, so that the circulation vehicle 7 can move along each track, facilitating the flow of food in different chambers.

[0040] The power source of the circulation vehicle 7 can be selected from the existing technology. The technical solution of this application does not improve this part, so it will not be described in detail.

[0041] In some embodiments, the fresh-keeping chamber 1, the freezing chamber 2 and the thawing chamber 3 are respectively provided with input channels 8, the input channels 8 are laid with input tracks 10, the input channels 8 are docked with the corresponding sub-tracks 5, and the fresh-keeping chamber 1, the freezing chamber 2 and the thawing chamber 3 are respectively provided with closed doors 9, which are used to open and close the input channels 8.

[0042] The input channel 8 is used for the circulation vehicle 7 to enter and exit the corresponding chamber. For example, to enter the fresh-keeping room 1, the closed door 9 is first opened, and then the circulation vehicle 7 can move from the sub-track 5 to the input track 10 and then enter the fresh-keeping room 1.

[0043] It should be noted that, in the embodiment of the present application, the gap between the sub-track 5 and the input track 10, and the gap between the main track 4 and the sub-track 5 and the turning track 13 respectively need to be kept within a reasonable range so that the circulation vehicle 7 will not fall off the track when passing through the gap.

[0044] In some embodiments, the transfer vehicle 7 includes a vehicle body and a temporary storage chamber 14. The vehicle body is movably arranged on the main track 4, and the temporary storage chamber 14 is used to place food. A partition 23 is arranged in the temporary storage chamber 14.

[0045] Guide wheels are provided at the bottom of the vehicle body so that the vehicle body can move along the track.

[0046] Partitions 23 are used to separate the temporary storage chamber 14. The number of partitions 23 can be set as needed, so that multiple small chambers are formed in the temporary storage chamber 14, which facilitates the classification and placement of food. For example, if a batch of food includes food that needs to be frozen and food that needs to be kept fresh, the two types of food can be placed in different small chambers and transported to different chambers in sequence using the transfer vehicle 7.

[0047] In some embodiments, the temporary storage chamber 14 includes two beams 15 spaced apart from each other in the upper and lower directions. Along the length direction of the beams 15, the two beams 15 are respectively provided with slide rails 28. The temporary storage chamber 14 is provided with a switch component, which includes a first support portion 16, a first roller 24, a second support portion 17, a flexible shielding portion 20 and a support member. The first support portion 16 is provided with a first sliding portion 26 on the upper and lower sides, respectively, and the first sliding portion 26 is slidably connected to the slide rail 28. The first roller 24 is rotatably connected to the first support portion 16, and the second support portion 17 is provided with a second sliding portion 27 on the upper and lower sides, respectively, and the second sliding portion 27 is slidably connected to the slide rail 28. The flexible shielding portion 20 is wound around the first roller 24 and connected to the second support portion 17. The support member is arranged between the first support portion 16 and the second support portion 17.

[0048] The temporary storage chamber 14 may be a frame structure, that is, a whole frame is formed by a plurality of beams 15 , and a chamber structure is formed by closing the middle portion of the frame.

[0049] The first supporting portion 16 and the second supporting portion 17 can move along the slide rails 28 , respectively.

[0050] The flexible shielding portion 20 can be made of waterproof fabric. The flexible shielding portion 20 is wound around a first roller 24, allowing for adjustable dimensions. The first support portion 16 can be provided with a locking mechanism to unlock or lock the first roller 24. When the length of the first roller 24 along the slide rail 28 needs to be adjusted, the first roller 24 can be unlocked, allowing adjustment. Otherwise, the first roller 24 can be locked, preventing rotation. The locking mechanism can be selected from existing configurations.

[0051] The support member is used to limit the distance between the first support portion 16 and the second support portion 17 .

[0052] The switch component can be used to form the side wall of the temporary storage cavity 14, that is, under the action of the support member, the first support portion 16 and the second support portion 17 cannot be closed. At this time, the flexible shielding portion 20 is straightened and can play a shielding role.

[0053] The switch component can also partially open the sidewall of the temporary storage chamber 14 to facilitate food removal. For example, although the top of the temporary storage chamber 14 can be open to facilitate food removal, removing the food requires lifting the food, which is inconvenient. Removing the food from the sidewall is more labor-saving. Furthermore, to increase the number of small chambers in the temporary storage chamber 14, multiple partitions 23 can be provided above and below, so that a small chamber can also be formed between two partitions 23. The food in the small chamber can only be removed from the sidewall.

[0054] When the support member releases its restraining action on the first support portion 16 and the second support portion 17, the first support portion 16 and the second support portion 17 can move along the slide rail 28. When the first support portion 16 and the second support portion 17 are closed, the side wall of the temporary storage chamber 14 can be opened, making it easier to take food in and out. The size and position of the opening formed in the side wall can be adjusted as needed.

[0055] In some embodiments, the support member includes two support chains 19 and two sprockets 30. The first support portion 16 is provided with two receiving slots 29, symmetrically arranged about a reference plane parallel to the horizontal plane. The two support chains 19 are selectively accommodated in one of the receiving slots 29. The receiving slots 29 include an outlet section 32 and a curved section 33 connected to the outlet section 32. The outlet section 32 extends through the side of the first support portion 16 facing the second support portion 17. The ends of the support chains 19 are connected to the second support portion 17 via the outlet section 32. The support chain 19 includes a plurality of chain links 22 rotatably connected in sequence. A limiter 21 is provided between two adjacent chain links 22. The limiter 21 is used to limit the rotation direction of the chain link 22 and is disposed on opposite sides of the two chain links 22. Two sprockets 30 are rotatably connected to the first support portion 16. The two sprockets 30 are respectively disposed on the inner curved sides of the two curved sections 33. The two support chains 19 engage with the corresponding sprockets 30.

[0056] The portion of the accommodating groove 29 connected to the side of the curved section 33 away from the outlet section 32 may extend in the vertical direction.

[0057] The two receiving grooves 29 are symmetrically arranged about a reference plane parallel to the horizontal plane, so that the outlet sections 32 of the two receiving grooves 29 are arranged up and down, thereby enabling the parts of the two support chains 19 extending out of the outlet sections 32 and connected to the second support parts 17 to be arranged up and down.

[0058] The limiting portion 21 is used to limit the rotation direction of the chain link 22. For the upper support chain 19, the limiting portion 21 is set below the chain link 22. This allows one of the two adjacent chain links 22 to rotate only upward relative to the other. This allows the upper support chain 19 to form a curved structure with the concave side facing upward when the entire chain is deformed. For the lower support chain 19, the limiting portion 21 is set above the chain link 22. This allows one of the two adjacent chain links 22 to rotate only downward relative to the other. This allows the lower support chain 19 to form a curved structure with the concave side facing downward when the entire chain is deformed. Because the two support chains 19 are arranged one above the other, they limit each other. This allows the two support chains 19 to form a rigid support structure.

[0059] The two sprockets 30 are respectively engaged with the corresponding support chains 19. On the one hand, the support chains 19 can be unlocked or locked by controlling the rotation of the sprockets 30. On the other hand, the sprockets 30 can guide the support chains 19, making it easier for the support chains 19 to move along the receiving slots 29.

[0060] Under the action of the limiting portion 21, when the two support chains 19 are moved out of the receiving groove 29, the two support chains 19 can be combined to form a rigid support structure to limit the distance between the first support portion 16 and the second support portion 17. For example, the first support portion 16 is fixed and the second support portion 17 is pulled away from the first support portion 16. As the support chains 19 are pulled out of the receiving groove 29, the two support chains 19 automatically form a rigid support structure, which is convenient and quick to operate. On the other hand, the support chains 19 are accommodated in the receiving groove 29, so that when the first support portion 16 and the second support portion 17 are closed, the support chains 19 will not hinder the closing of the two, thereby increasing the maximum extent to which the opening can be opened, and the overall structure of the switch component is very compact, reducing the risk of encroaching on the internal space of the temporary storage chamber 14. On the other hand, the deformable structure of the support chain 19 can be set as long as possible by reasonably setting the shape of the receiving groove 29, thereby increasing the area that can be covered by the switch component. On the other hand, the links 22 of the support chain 19 can be set as a detachable structure with reference to existing chains, so that the length of the support chain 19 can be adjusted as needed, and the size of the switch component can also be adjusted as needed.

[0061] In some embodiments, the support member also includes two pawls 31, which are rotatably connected to the first support portion 16. The two pawls 31 are arranged corresponding to the two sprockets 30. When the sprocket 30 is configured to support the chain 19 and move out of the exit section 32, the sprocket 30 rotates along the first direction, and the pawl 31 is clamped between two adjacent teeth of the sprocket 30. The pawl 31 is tilted in the first direction, and an elastic member is arranged between the pawl 31 and the first support portion 16.

[0062] Reference Figure 9 In the state shown in , the first direction of the upper sprocket 30 is counterclockwise, and the first direction of the lower sprocket 30 is clockwise.

[0063] The pawl 31 is tilted in the first direction so that when the sprocket 30 rotates, the pawl 31 can sequentially pass through each tooth portion of the sprocket 30. However, when the pawl 31 rotates in the opposite direction, the pawl 31 is stuck between the teeth, so that the sprocket 30 cannot rotate in the opposite direction.

[0064] The specific position of the pawl 31 can be referred to Figure 9 As shown in .

[0065] The elastic member can be a spring, which is used to provide an elastic force that enables the pawl 31 to remain against the peripheral wall of the sprocket 30 .

[0066] The pawl 31 can limit the sprocket 30. When the side wall of the temporary storage chamber 14 needs to be opened, the pawl 31 is rotated to control the position of the pawl 31 so that it cannot release the wall of the sprocket 30. At this time, the sprocket 30 can rotate in the opposite direction relative to the first direction.

[0067] In some embodiments, the first roller 24 is drivingly connected to a sprocket 30 .

[0068] One of the two sprockets 30 is in transmission connection with the first roller 24 , so that when the driving support chain 19 moves into the accommodating groove 29 , the support chain 19 drives the sprocket 30 to rotate, and the sprocket 30 can drive the first roller 24 to rotate.

[0069] The advantage of this arrangement is that when the support chain 19 moves into the receiving groove 29, the sprocket 30 rotates, and the first roller 24 can rotate in the direction of retracting the flexible shielding portion 20, so that when the first support portion 16 and the second support portion 17 are closed, the flexible shielding portion 20 can be retracted synchronously, thereby reducing the risk of the flexible shielding portion 20 obstructing the closing of the first support portion 16 and the second support portion 17. Specifically, when the temporary storage chamber 14 is full of food, when the first support portion 16 and the second support portion 17 are closed, if the flexible shielding portion 20 cannot be retracted, the flexible shielding portion 20 will be folded due to the closing of the first support portion 16 and the second support portion 17. However, due to the obstruction of the support chain 19 and the obstruction of the food in the temporary storage chamber 14, the folding space of the flexible shielding portion 20 is limited, and the flexible shielding portion 20 will accumulate between the first support portion 16 and the second support portion 17, preventing the first support portion 16 and the second support portion 17 from closing. At the same time, the first roller 24 is connected to the sprocket 30, so that the flexible shielding portion 20 can also apply force to the second support portion 17, pulling the second support portion 17 toward the first support portion 16. In addition, when the sprocket 30 is locked by the pawl 31, the first roller 24 can also be locked. The two share a locking structure, making it easier to control the switch component.

[0070] The specific structure of the transmission connection between the sprocket 30 and the first roller 24 can be selected from the existing structures. For example, in the embodiment of the present application, since the rotation axis of the sprocket 30 is perpendicular to the rotation axis of the first roller 24, the transmission structure adopts a gear set transmission, and the gear set includes two bevel gears 34 and two spur gears 35. One bevel gear 34 is coaxially connected to the sprocket 30, and the other bevel gear 34 is rotatably connected to the first support part 16, with the axis parallel to the axis of the first roller 24. The two bevel gears 34 are meshed. One of the two spur gears 35 is coaxially connected to the first roller 24, and the other is coaxially connected to the bevel gear 34 whose axis is parallel to the first roller 24. The two spur gears 35 are meshed, so that when the sprocket 30 rotates, the first roller 24 can rotate synchronously.

[0071] In some embodiments, the first support portion 16 is further provided with a connecting rope 18 , and both ends of the connecting rope 18 are respectively connected to one side of the two support chains 19 away from the outlet section 32 .

[0072] The first support portion 16 may be provided with two wire holes, which are respectively connected to the ends of the two accommodating grooves 29 away from the outlet section 32 , and the two ends of the connecting rope 18 are connected to the ends of the two support chains 19 away from the outlet section 32 through the two wire holes.

[0073] Such arrangement enables the two supporting chains 19 to be pulled and moved when the connecting rope 18 is pulled. Simultaneously, the connecting rope 18 can limit the two supporting chains 19 so that the supporting chains 19 cannot escape from the accommodating groove 29.

[0074] In some embodiments, the switch component further includes a second roller 25 , which is rotatably disposed on the second support portion 17 , and the flexible shielding portion 20 is wound around the second roller 25 .

[0075] The second roller 25 is used to adjust the length of the flexible shielding portion 20. The second support portion 17 can be provided with a locking structure to unlock or lock the second roller 25. When locked, the second roller 25 cannot rotate relative to the second support portion 17. When unlocked, the second roller 25 can rotate relative to the second support portion 17. The locking structure can be selected from existing structures and will not be described in detail here.
