[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0033] Example, see Figure 1~Figure 2 , is an embodiment of the utility model, which proposes a food raw material sample cabinet, including a refrigerating cabinet body 1, a control cabinet body 2, a cooling coil 3, an air intake manifold 4, and an exhaust manifold 5. The control cabinet body 2 has a cold air outlet and a reflux port; the cooling coil 3 is arranged in the refrigerating cabinet body 1, the number of the cooling coil 3 is at least two, and all the cooling coils 3 are arranged in the up and down direction for carrying the sample food; the air intake manifold 4 is arranged in the refrigerating cabinet body 1, and the inlet ends of the cooling coil 3 are connected to the air intake manifold 4, and the inlet end of the air intake manifold 4 is connected to the cold air outlet; the exhaust manifold 5 is arranged in the refrigerating cabinet body 1, and the outlet ends of the cooling coil 3 are connected to the exhaust manifold 5, and the outlet end of the exhaust manifold 5 is connected to the reflux port.
[0034] Furthermore, if Figure 3 and Figure 4As shown, the refrigerator also includes a refrigerator door 6, which is sealed on the front of the refrigerator body 1, one side of the refrigerator door 6 is hinged to the refrigerator body 1, and the other side of the refrigerator door 6 is detachably connected to the refrigerator body 1, and the air intake manifold 4 and the exhaust manifold 5 are both located on the side of the refrigerator body 1 away from the refrigerator door 6. After closing the refrigerator door 6, the sample food can be sealed in the refrigerator body 1, which can prevent the sample food from being affected by the external temperature.
[0035] Furthermore, if Figure 1 and Figure 3 As shown, the control cabinet 2 is arranged below the refrigerating cabinet 1, and the control cabinet 2 is detachably connected to the refrigerating cabinet 1, so that the control cabinet 2 can be easily maintained.
[0036] Furthermore, if Figure 1 and Figure 5 As shown, it also includes a heat insulation board 7, which is arranged in the refrigerating cabinet 1. A slot is provided on the side of the heat insulation board 7 facing the cooling coil 3, and the two ends of the cooling coil 3 are respectively plugged into the slots at the corresponding ends. The cooling coil 3 is separated from the refrigerating cabinet 1 by the heat insulation board 7, so that heat transfer caused by direct contact between the cooling coil 3 and the refrigerating cabinet 1 can be avoided, and the heat insulation effect is better.
[0037] Furthermore, if Figure 5 As shown, a dovetail groove is provided on the inner wall of the refrigerator body 1, and the end surface shape of the heat insulation board 7 facing the dovetail groove matches the shape of the dovetail groove, and the heat insulation board 7 is plugged into the dovetail groove. The left and right ends of the dovetail strip of the heat insulation board 7 are respectively plugged into the dovetail groove on the refrigerator body 1, which can prevent the heat insulation board 7 from shaking left and right, and has better stability. When the refrigerator door 6 is closed, the heat insulation board 7 is clamped between the refrigerator door 6 and the refrigerator body 1, which can prevent the heat insulation board 7 from shaking back and forth.
[0038] Furthermore, the cooling coil 3 is detachably connected to the intake manifold 4, and the cooling coil 3 is detachably connected to the exhaust manifold 5. When a cooling coil 3 has a problem, it can be directly removed and replaced with a new cooling coil 3, which has a simple structure and is easy to maintain.
[0039] Furthermore, if Figure 6As shown, the first connecting sleeve 8 is also included. The first connecting sleeve 8 is sealed and arranged between the inlet end of the cooling coil 3 and the air intake manifold 4. The first connecting sleeve 8 and the air intake manifold 4 are threadedly connected, and the first connecting sleeve 8 and the cooling coil 3 are also threadedly connected. Taking the air intake manifold 4 located at the bottom of the refrigerating cabinet 1 as an example, when the cooling coil 3 needs to be disassembled, the first connecting sleeve 8 can be rotated first so that the first connecting sleeve 8 moves toward the air intake manifold 4 (i.e., downward). When the first connecting sleeve 8 is separated from the cooling coil 3, the cooling coil 3 can be moved. When installing the cooling coil 3, the cooling coil 3 is first installed on the refrigerating cabinet 1. At this time, the lower end of the cooling coil 3 is located directly above the first connecting sleeve 8. Then, the first connecting sleeve 8 is rotated so that the first connecting sleeve 8 moves away from the air intake manifold 4 (i.e., upward) until the first connecting sleeve 8 is threadedly connected to the air intake manifold 4 and the cooling coil 3 at the same time. The structure is simple, the connection is firm and reliable, and the disassembly and assembly are convenient and fast, saving time and effort.
[0040] Furthermore, if Figure 6 As shown, it also includes a first limiting ring 9, which is arranged on the periphery of the first connecting sleeve 8. The first connecting sleeve 8 is located between the first limiting ring 9 and the air intake manifold 4, and the distance between the first limiting ring 9 and the air intake manifold 4 is less than the length of the first connecting sleeve 8. Taking the air intake manifold 4 located at the bottom of the refrigerating cabinet 1 as an example, when installing the cooling coil 3, it is necessary to rotate the first connecting sleeve 8 so that the first connecting sleeve 8 moves away from the air intake manifold 4 (i.e. upward). When the first connecting sleeve 8 contacts the first limiting ring 9, the first connecting sleeve 8 cannot continue to move upward, which can remind the operator to install it in place, so as to avoid the first connecting sleeve 8 from rotating too much and separating from the air intake manifold 4.
[0041] Furthermore, if Figure 7 As shown, the second connecting sleeve 10 is also included. The second connecting sleeve 10 is sealed and arranged between the outlet end of the cooling coil 3 and the exhaust manifold 5. The second connecting sleeve 10 and the exhaust manifold 5 are threadedly connected, and the second connecting sleeve 10 and the cooling coil 3 are also threadedly connected. Taking the exhaust manifold 5 located at the top of the refrigerating cabinet 1 as an example, when the cooling coil 3 needs to be removed, the second connecting sleeve 10 can be rotated first to move the second connecting sleeve 10 toward the exhaust manifold 5 (i.e., upward). When the second connecting sleeve 10 is separated from the cooling coil 3, the cooling coil 3 can be moved. When installing the cooling coil 3, the cooling coil 3 is first installed on the refrigerating cabinet 1. At this time, the upper end of the cooling coil 3 is located directly below the second connecting sleeve 10. Then, the second connecting sleeve 10 is rotated to move the second connecting sleeve 10 away from the exhaust manifold 5 (i.e., downward), until the second connecting sleeve 10 is threadedly connected to the exhaust manifold 5 and the cooling coil 3 at the same time. The structure is simple, the connection is firm and reliable, and the assembly and disassembly are convenient and quick, saving time and effort.
[0042] Furthermore, if Figure 7 As shown, it also includes a second limiting ring 11, which is arranged on the periphery of the second connecting sleeve 10, and the second connecting sleeve 10 is located between the second limiting ring 11 and the exhaust manifold 5, and the spacing between the second limiting ring 11 and the exhaust manifold 5 is less than the length of the second connecting sleeve 10. Taking the exhaust manifold 5 located at the top of the refrigerating cabinet 1 as an example, when installing the cooling coil 3, it is necessary to rotate the second connecting sleeve 10 so that the second connecting sleeve 10 moves away from the exhaust manifold 5 (i.e., downward). When the second connecting sleeve 10 contacts the second limiting ring 11, the second connecting sleeve 10 cannot move further downward, which can remind the operator to install it in place, so as to avoid the second connecting sleeve 10 from rotating too much and separating from the exhaust manifold 5.
[0043] In this embodiment, the control cabinet 2 has a cold air outlet and a return port, and all cooling coils 3 are arranged in the vertical direction in the refrigerating cabinet 1, and are inserted on the inner wall of the refrigerating cabinet 1 through the heat insulation board 7. Taking the intake manifold 4 located at the bottom of the refrigerating cabinet 1 and the exhaust manifold 5 located at the top of the refrigerating cabinet 1 as an example, the inlet end of the cooling coil 3 is connected to the intake manifold 4 through the first connecting sleeve 8, and the outlet end of the cooling coil 3 is connected to the exhaust manifold 5 through the second connecting sleeve 10. The inlet end of the intake manifold 4 is connected to the cold air outlet of the control cabinet 2, and the outlet end of the exhaust manifold 5 is connected to the return port of the control cabinet 2. When the first connecting sleeve 8 is moved downward and the second connecting sleeve 10 is moved upward, so that the spacing between the first connecting sleeve 8 and the second connecting sleeve 10 corresponding to a certain cooling coil 3 is greater than the spacing between the upper and lower ends of the cooling coil 3, the cooling coil 3 can be pulled out from between the left and right heat insulation boards 7, or the cooling coil 3 can be inserted between the left and right heat insulation boards 7.
[0044] Compared with the cold air passing through all the sampled foods in sequence from top to bottom, the utility model allows the cold air in the control cabinet 2 to enter the air intake main pipe 4 through the cold air outlet, and then be diverted to each cooling coil 3, and then enter the exhaust main pipe 5, and return to the control cabinet 2 through the reflux port. The cooling coil 3 cools the sampled foods placed thereon, which can reduce the upper and lower temperature differences in the refrigeration cabinet 1 and improve the temperature uniformity in the refrigeration cabinet 1.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
