[0002] A central kitchen refers to a business entity established by a food business, with independent premises and facilities, that centrally processes and produces finished or semi-finished food products and distributes them to its chain stores for further processing and production before providing them to consumers.

[0003] Pre-cooked meals typically need to be stored in a low-temperature environment, but different ingredients and pre-cooked meals require different storage temperatures, such as -40℃, -20℃, and 0℃. Currently, multiple storage rooms are usually designed, with each storage room equipped with a separate refrigeration system. Each storage room has a different refrigeration temperature to meet the needs. However, for some locations with limited space, users may not be able to allocate multiple storage rooms, and equipping each storage room with a separate refrigeration system can lead to higher costs.

[0034] Please see Figures 1 to 3 One embodiment of this utility model provides a refrigeration system for storing pre-prepared dishes in a central kitchen, used to regulate the temperature of a storage room 30, including: a refrigeration unit 10 and multiple heat-insulating walls 20.

[0035] The structure and refrigeration principle of the refrigeration unit 10 are well known to those skilled in the art and will not be described in detail here.

[0036] The heat insulation wall 20 is provided with a ventilation opening 21, and a heat conduction component 22 and a fan component 23 are provided inside the ventilation opening 21.

[0037] The heat insulation wall 20 divides the storage room 30 into multiple storage zones 31, which are arranged sequentially from the first side to the second side of the storage room 30. The first side and the second side are opposite sides of the storage room 30. Adjacent storage zones 31 are connected through the ventilation opening 21. The refrigeration unit 10 is arranged in the storage room 30 and is located in the storage zone 31 closest to the first side. The fan assembly 23 is used to drive air to flow from the first side to the second side of the storage room 30.

[0038] The heat insulation wall 20 includes multiple heat insulation panels 24, one of which is provided with a ventilation opening 21. The multiple heat insulation panels 24 are arranged sequentially from the third side to the fourth side of the storage room 30, and adjacent heat insulation panels 24 can be detached and fitted together.

[0039] The heat-conducting component 22 is used for heat transfer between adjacent storage compartments 31 to achieve temperature regulation, while the fan component 23 is used to accelerate the temperature regulation speed.

[0040] In this embodiment, the storage room 30 is provided with two heat insulation walls 20 as an example. The two heat insulation walls 20 divide the storage room 30 into three storage partitions 31. From the first side to the second side of the storage room 30, they are the first storage partition 31, the second storage partition 31 and the third storage partition 31 in sequence. The refrigerator 10 is located in the first storage partition 31.

[0041] When the refrigerator 10 is running, the temperature in the first storage compartment 31 is matched with the cooling temperature set by the refrigerator 10. The heat-conducting component 22 between the first and second storage compartments 31 conducts heat, so that the second storage compartment 31 is also cooled down by the cooling effect of the refrigerator 10. However, due to the influence of the heat insulation wall 20, the temperature of the second storage compartment 31 is higher than that of the first storage compartment 31. Similarly, the temperature of the third storage compartment 31 is higher than that of the second storage compartment 31. For example, the temperatures of the first, second, and third storage compartments 31 are -40℃, -20℃, and 0℃, respectively. The fan assembly 23 is used to actively regulate the temperature of the second and third storage compartments 31. For example, if the temperature of the second storage compartment 31 is not low enough, the fan assembly 23 can be turned on, causing the cold air from the first storage compartment 31 to blow towards the second storage compartment 31, thereby regulating the temperature of the second storage compartment 31. Similarly, the temperature of the third storage compartment 31 can also be regulated by the corresponding fan assembly 23. Moreover, since the air driven by the fan assembly 23 passes through the heat-conducting component 22, it is beneficial for the air to exchange heat with the heat-conducting component 22, improving the effect of the fan assembly 23 in actively regulating the temperature. The principle is that since the heat-conducting component 22 is located between the first and second storage compartments 31, due to the heat exchange between the first and second storage compartments 31, the temperature of the heat-conducting component 22 is higher than that of the first storage compartment 31. The fan assembly 23 can drive the air from the first storage compartment 31 to come into contact with the heat-conducting component 22, causing the temperature of the heat-conducting component 22 to decrease, which in turn helps to cool down the second storage compartment 31.

[0042] In some alternative embodiments, the refrigerator 10 is arranged on the third side of the storage chamber 30; in the direction from the first side to the second side of the storage chamber 30, the vents 21 of the plurality of insulation walls 20 are arranged sequentially from the third side to the fourth side of the storage chamber 30, so that the cold air generated by the refrigerator 10 can better enter the second storage chamber 30 from the first storage chamber 30, but will not directly enter the third storage chamber 30, thereby more precisely controlling the temperature of different storage chambers 30. In this embodiment, in the insulation wall 20 between the first and second storage chambers 30, the vents 21 are located on the insulation plate 24 closest to the third side of the storage chamber 30, while in the insulation wall 20 between the second and third storage chambers 30, the vents 21 are located on the insulation plate 24 furthest from the third side of the storage chamber 30.

[0043] In some alternative embodiments, the heat-conducting component 22 and the fan assembly 23 are arranged sequentially in the vent 21 from the first side to the second side of the storage chamber 30, thereby bringing the heat-conducting component 22 as close as possible to the lower-temperature storage chamber 30 to achieve heat conduction. Of course, it is also feasible to arrange the fan assembly 23 and the heat-conducting component 22 sequentially in the vent 21 from the first side to the second side of the storage chamber 30.

[0044] In some optional embodiments, a mounting frame 211 is provided inside the vent 21, a portion of which extends beyond the vent 21 and protrudes from opposite sides of the heat insulation plate 24. The mounting frame 211 is used to lengthen the vent 21, facilitating the installation of the heat-conducting assembly 22 and the fan assembly 23.

[0045] In some alternative embodiments, adjacent heat insulation panels 24 are detachably connected by a plurality of connecting components 25 arranged sequentially from top to bottom.

[0046] In some alternative embodiments, the heat-conducting component 22 includes a plurality of heat-conducting pipes 221 arranged side by side in the vent 21, with air passing between adjacent heat-conducting pipes 221.

[0047] In some alternative embodiments, the fan assembly 23 includes a plurality of blowers 231 arranged side by side within the vent 21. The structure of the blowers 231 is well known to those skilled in the art and will not be described in detail here.

[0048] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6 In some optional embodiments, the heat insulation plate 24 has a plurality of connecting holes 241 arranged sequentially from top to bottom on its side. The connecting holes 241 are connected to through holes 242, which communicate with opposite sides of the heat insulation plate 24. The connecting assembly 25 includes an insert 251 and two threaded locking members 252. The insert 251 has two mounting holes 2511, and both ends of the insert 251 extend into adjacent heat insulation plates 24. Within the connecting hole 241, the mounting hole 2511 communicates with the through hole 242 of the adjacent heat insulation plate 24. The threaded locking member 252 passes through the mounting hole 2511 and the through hole 242. The threaded locking member 252 restricts the position of the insert 251 relative to the heat insulation plate 24, so that the insert 251 cannot detach from the connecting hole 241. The insert 251 restricts the position of the two heat insulation plates 24, so that the two heat insulation plates 24 cannot be separated.

[0049] The connection method between the mounting hole 2511 and the threaded locking member 252 can be selected according to actual needs. For example, the threaded locking member 252 can directly engage with the mounting hole 2511 via a thread. Alternatively, in some optional embodiments, the threaded locking member 252 includes a threaded sleeve 253 and a screw 254. The threaded sleeve 253 extends from one side of the heat insulation plate 24 into the through hole 242 and the mounting hole 2511, and the screw 254 passes through the other side of the heat insulation plate 24 and extends into the through hole 242. Then, it engages with the threaded sleeve 253. The end of the threaded sleeve 253 forms a limiting cap 2531, which engages with one side of the heat insulation plate 24. The limiting cap 2531 restricts the axial position of the threaded sleeve 253 relative to the through hole 242. The cap of the screw 254 can also restrict the axial position of the screw 254 relative to the through hole 242. Therefore, the threaded locking member 252 is stably fixed in the through hole 242 on the heat insulation plate 24, thereby stably restricting the position of the insert 251.

[0050] The connection method between the heat insulation panel 24 and the storage chamber 30 can be selected according to actual needs. For example, in some optional embodiments, multiple corner pieces 26 are provided on the sides of the heat insulation panel 24 at the head end and the heat insulation panel 24 at the tail end in the direction from the third side to the fourth side of the storage chamber 30. Expansion screws 254 (not shown) are provided on the corner pieces 26 for connection with the side wall of the storage chamber 30. The heat insulation panel 24 can also be fixed in the storage chamber 30 in other suitable ways. For example, a bracket is provided in the storage chamber 30, and a slot is provided at the bottom of the bracket. The bottom of the heat insulation panel 24 is inserted into the slot, and the side of the heat insulation panel 24 abuts against the side of the bracket, so that the heat insulation panel 24 is stably supported by the bracket in the storage chamber 30.

[0051] The insulation board 24 is also provided with a wiring trough 27. The wiring troughs 27 on adjacent insulation boards 24 are connected to each other, and the wires connected to the fan assembly 23 can be run through the wiring trough 27.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
