[0001] The present invention relates to the field of express delivery cabinets, and in particular to a foam cabinet body for refrigeration equipment and refrigeration equipment. Background Art

[0002] At present, refrigeration equipment is widely used in people's daily life. With the continuous development of the express delivery industry, express delivery cabinets with refrigeration function are widely used. Express delivery cabinets usually include a cabinet body and a cabinet door. A plurality of beams are arranged on the inner liner of the cabinet body, and the inner liner is divided into a plurality of storage compartments with partitions. Each storage compartment is provided with a cabinet door that can be opened and closed. At the same time, a central control panel is also arranged on the cabinet body, and the inner side of the central control panel is used to install related electrical components (for example: electronic locks, electric control panels, etc.). For the cabinet body, during the foaming process, due to the influence of the beams arranged on the inner liner, the part of the inner liner side wall located on the rear side of the beam cannot be supported by the foaming expansion and contraction mold, and is easily squeezed and deformed by the expanded foaming material, resulting in poor foaming quality and low yield rate of the cabinet body. How to design a technology to improve the foaming quality of the foaming cabinet body to improve the yield rate is the technical problem to be solved by the present invention.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-Figure 20 As shown, the refrigeration equipment of this embodiment includes a foam cabinet 1, multiple door bodies 2 and a refrigeration system, wherein the foam cabinet 1 includes an outer shell 1-1, an inner tank 1-2 and a center beam 1-3, and a foam cavity is formed between the outer shell 1-1, the inner tank 1-2 and the center beam 1-3, wherein a plurality of cross beams 10 are arranged on the tank opening of the inner tank 1-2, and the plurality of cross beams 10 divide the tank opening of the inner tank 1-2 into a plurality of cabinet opening structures, so that the inner tank 1-2 can be divided into a plurality of storage spaces 11 by the cross beams 10, and two adjacent storage spaces 11 are separated by a partition 7, a central control panel 3 is arranged on the center beam 1-3 of the foam cabinet 1, and a central control cover 4 is arranged on the central control panel 33, and the refrigeration system includes a compressor 14, a condenser 15, a throttling device and an evaporator 18 connected together. The foam cabinet 1 is equipped with a door body 2 for opening and closing the storage space 11, and the electric lock 51 is installed on the central beam 1-3, and the electric control board 6 is installed on the central control cover 4, so that the electric control board 6 can control the electric lock 51 to unlock the door body 2.

[0040] The refrigeration equipment of this embodiment is improved in multiple aspects, such as foam insulation, central control waterproofing, and improving space utilization, as described below:

[0041] In order to improve the insulation of the foam cabinet 1 and avoid the phenomenon of reduced insulation performance due to insufficient injection of foaming material in the beam 10, the beam 10 includes a shell 101 and an insulation filling block 102, an installation cavity is formed in the shell 101, and the insulation filling block 102 is located in the installation cavity; the installation cavity is also connected to the foaming cavity, and the installation cavity and the foaming cavity are both provided with a foam insulation layer. Specifically, before the crossbeam 10 is installed on the inner liner 1-2, an insulating filling block 102 is first installed in the outer shell 1-1 of the crossbeam 10. The insulating filling block 102 can ensure that the thermal insulation performance of the crossbeam 10 meets the requirements. After the crossbeam 10 is installed on the inner liner 1-2, the inner liner 1-2, the middle beam 1-3 and the outer shell 1-1 form a foaming cavity. During the foaming process, the foaming material in the foaming cavity can also enter the installation cavity. In this way, the foaming material entering the installation cavity makes the crossbeam 10 and the inner liner 1-2 more tightly and firmly connected together. The outer shell 1-1, the middle beam 1-3, the inner liner 1-2 and the crossbeam 10 can be firmly connected together by using the foaming material, and the gaps formed at the connections between the various components can also be filled with the foaming material, further improving the sealing performance. Among them, in order to facilitate the installation of the beam 10 on the inner tank 1-2, the two side walls of the inner tank 1-2 are respectively provided with multiple installation grooves 1-20, and the ends of the shell 101 are set in the corresponding installation grooves 1-20, and the two ends of the outer shell 1-1 can be snapped into the corresponding installation grooves 1-20 to facilitate the operator to quickly assemble the beam 10 to the inner tank 1-2, and the end face of the shell 101 is provided with an injection interface 100 forming a connection with the installation cavity, and the installation cavity is connected with the foaming cavity through the injection interface 100, and the foaming material injected into the foaming cavity enters the installation cavity through the injection interface 100, and the foaming material entering the installation cavity will be filled into the gap between the thermal insulation filling block 102 and the inner wall of the outer shell 1-1. The installation groove 1-20 is provided with a through hole 1-201, and the injection interface 100 is inserted into the through hole 1-201. The injection interface 100 can be connected with the foaming cavity through the through hole 1-201. Preferably, the surface of the thermal insulation filling block 102 is also provided with a flow channel (not marked) for the foaming material to flow, and the foaming material entering the installation cavity can be guided by the flow channel and quickly flow into the inner area of ​​the installation cavity.In addition, in order to facilitate the installation of the thermal insulation filling block 102 into the shell 101, the shell 101 includes an upper shell 1011 and a lower shell 1012, and the upper shell 1011 and the lower shell 1012 are clamped together. Specifically, the edge of the upper shell 1011 is provided with a plurality of first claws (unmarked), and the edge of the lower shell 1012 is provided with a plurality of first clamping holes (unmarked), and the first claws are clamped in the corresponding first clamping holes. When the crossbeam 10 is assembled, the thermal insulation filling block 102 is placed between the upper shell 1011 and the lower shell 1012, and then the upper shell 1011 and the lower shell 1012 are clamped together through the cooperation of the first claws and the first clamping holes.

[0042] Furthermore, in order to facilitate the installation of the door body 2, the crossbeam 10 also includes a sheet metal decorative panel 102, which is arranged on the front side of the shell 101. One end of the sheet metal decorative panel 102 is provided with a mounting hole (not marked) for installing a door hinge. Specifically, the crossbeam 10 is provided with a sheet metal decorative panel 102. The sheet metal decorative panel 102 adopts a sheet metal component with high overall structural strength, which can ensure the installation requirements of the door hinge. After long-term use, the sheet metal decorative panel 102 will not be deformed, thereby ensuring the installation reliability of the door body 2. In order to improve the installation reliability of the sheet metal decorative plate 102, the sheet metal decorative plate 102 is clamped between the upper shell 1011 and the lower shell 1012. Specifically, the upper and lower edges of the sheet metal decorative plate 102 are respectively provided with a flange structure (not marked), and the flange structure is provided with a second clamping hole (not marked). The upper shell 1011 and the lower shell 1012 are respectively provided with a second clamping claw (not marked) that cooperates with the second clamping hole. The second clamping claw is clamped in the corresponding second clamping hole. The sheet metal decorative plate 102 is firmly fixed by the cooperation of the second clamping claw and the second clamping hole. Stuck between the upper shell 1011 and the lower shell 1012, correspondingly, the installation cavity is formed between the upper shell 1011, the lower shell 1012 and the sheet metal decorative plate 102, so that the foaming material entering the installation cavity will further firmly connect the upper shell 1011, the lower shell 1012 and the sheet metal decorative plate 102 together, preferably, slot structures 1016 are respectively provided on the upper shell 1011 and the lower shell 1012, the flange structure is inserted into the corresponding slot structure 1016, and the second claw is provided in the slot structure 1016. In addition, in order to better improve the structural strength, a reinforcing iron 104 is also provided in the installation cavity. The reinforcing iron 104 has an installation surface and supporting surfaces located on both sides of the installation surface. The reinforcing iron 104 is a U-shaped structure, and the installation surface of the reinforcing iron 104 is abutted against the sheet metal decorative panel 102. Specifically, the reinforcing iron 104 is located in the installation cavity and is used to strengthen the structural strength of the door hinge installation portion of the sheet metal decorative panel 102. During the installation of the door hinge, the screws pass through the installation holes on the door hinge and the installation holes of the sheet metal decorative panel 102 and are threadedly connected to the reinforcing iron 104. At the same time, in order to improve the connection strength between the reinforcing iron 104 and the foamed insulation layer formed in the installation cavity, a plurality of openings (not marked) for the foaming material to flow through are provided on the support surface; the reinforcing iron 104 is located on one side of the injection interface, and after foaming, the reinforcing iron 104 is embedded in the foamed insulation layer in the beam 10, and the foaming material can firmly and reliably connect the shell 101, the insulation filling block 102, the sheet metal decorative panel 102 and the reinforcing iron 104 into an integral structure.Among them, the two ends of the sheet metal decorative plate 102 are also provided with a first folding edge 1021, and the second folding edge 1041 is provided on the installation surface. The first folding edge 1021 overlaps the side edge of the inner liner 1-2, and the second folding edge 1041 is abutted against the corresponding first folding edge 1021. The folding edge can increase the connection area between the sheet metal decorative plate 102 and the reinforcing iron 104 to improve the connection reliability. At the same time, the first folding edge 1021 overlaps the side edge of the inner liner 1-2 to protect the side of the inner liner 1-2. In order to avoid frost on the sheet metal decorative plate 102 due to cold during use, a dew-removing pipe is also provided between the heat-insulating filling block 102 and the sheet metal decorative plate 102. The heat generated by the dew-removing pipe is used to heat the sheet metal decorative plate 102 to avoid frost on the sheet metal decorative plate 102. At the same time, the heat generated by the dew-removing pipe is blocked by the heat-insulating filling block and transmitted into the inner liner 1-2 to ensure that the items in the inner liner 1-2 are well refrigerated.

[0043] Among them, during the foaming process, since multiple beams 10 are arranged at the opening of the inner tank 1-2, the foaming cabinet 1 needs to use an expansion and contraction mold to support the inner wall of the inner tank 1-2 during the foaming process. Since the expansion and contraction mold needs to avoid the beam 10 to enter and exit the inner tank, the part of the side wall of the inner tank 1-2 adjacent to the beam 10 cannot be supported by the foaming mold. During the foaming process, the area close to the inner tank 1-2 and the beam 10 will be deformed due to the extrusion of the foaming material, and a convex structure 1-21 convex inwardly is formed on the two side walls of the inner tank 1-2, and the convex structure 1-21 is located on the rear side of the corresponding beam 10. In this way, after the expansion and contraction mold enters the inner tank 1-2 and is unfolded, the lateral part in the expansion and contraction mold The extended template avoids the beam 10 and the raised structure 1-21 correspondingly and rests on the side wall of the inner liner 1-2, and the template longitudinally extended by the expansion and shrinkage mold will move to the raised structure 1-21 to support the surface of a pile of raised structures 1-21. In this way, during the foaming process, the side wall of the inner liner 1-21 located on the rear side of the beam 10 can obtain the support of the expansion and shrinkage mold through the formed raised structure 1-21. During the foaming process, it can be ensured that the shape of the inner liner 1-2 will not be deformed to improve the foaming quality. In this way, the problem in the prior art that the area of ​​the inner liner 1-2 located on the rear side of the beam 10 is not supported and deformed during the foaming process due to the expansion and shrinkage mold avoiding the beam 10 can be solved. The thickness of the raised structure 1-21 protruding from the side wall of the inner liner 1-2 is not less than 6 mm, and the raised structure 1-21 protruding from the side wall of the inner liner 1-2 has a sufficient height to ensure that the laterally extending template of the expansion and shrinking mold can be extended and translated to the surface of the raised structure 1-21 for support; at the same time, the height of the raised structure 1-21 is not greater than the height of the beam 10 to ensure that when the expansion and shrinking mold extends into the inner liner 1-2, the expansion and shrinking mold will not be hindered from continuing to move by the raised structure 1-21 after passing through the beam 10. The installation grooves 1-20 on the two side walls of the inner tank 1-2 are located in front of the raised structure 1-21. In this way, after the cross beam 10 is installed in the installation grooves 1-20, the raised structure 1-21 is shielded from the front. At the same time, during the foaming process, the foaming space at the raised structure 1-21 is larger, and more foaming material enters. The foaming material at the raised structure 1-21 can more easily pass through the through hole 1-201 of the installation groove 1-20 and enter the cross beam 10, so as to ensure that sufficient foaming material is provided to the cross beam 10. Preferably, in order to meet the positioning support of the partition 7, a convex block is formed on the side wall of the rear end of the convex structure 1-21, and the front end of the partition 7 is supported by the cross beam 10, while the rear end of the partition 7 is supported by the convex block.

[0044] In addition, in order to reduce the amount of foaming material used and thus reduce manufacturing costs, a flow guide filling block 1-5 is also provided between the two inner tanks 1-2. The flow guide filling block 1-5 can be made of a lightweight material with heat-insulating properties such as plastic foam. The flow guide filling block 1-5 is located in the foaming cavity. Specifically, since there is a middle beam 1-3 between the two inner tanks 1-2, the distance between the two inner tanks 1-2 is relatively large, and correspondingly more foaming material needs to be injected to fill the area between the two inner tanks 1-2. By adding the flow guide filling block 1-5 between the two inner tanks 1-2, the flow guide filling block 1-5 can save the amount of foaming material used on the one hand, and on the other hand, the flow guide filling block 1-5 is provided between the two inner tanks 1-2, and during the foaming process, the two inner tanks 1-2 can be positioned to avoid displacement of the inner tanks 1-2 caused by solidification of the foaming material. The structure of the flow guide filling block 1-5 can have a variety of forms.

[0045] For example: Fig.21 As shown, the guide filling block 1-5 forms a plurality of material channels for the foaming material to flow between the two inner tanks 1-2; the foaming material injected into the foaming cavity can flow between the two inner tanks 1-2 through the material channels to ensure that the foaming material in the area where the two inner tanks 1-2 are located is evenly distributed, thereby improving the thermal insulation performance of the foaming insulation layer. Among them, the front of the guide filling block 1-5 is provided with a plurality of transversely arranged guide grooves 1-51', and the material channels are formed between the guide grooves 1-51' and the middle beam 1-3. In addition, the back of the guide filling block 1-5 is provided with a plurality of raised pads 1-52', and the pads 1-52' are abutted against the back plate 1-14 of the outer shell 1-1. Under the action of the pads 1-52', a gap is formed between the back plate 1-14 and the guide filling block 1-5, so that the foaming material can smoothly fill the area between the back plate 1-14 and the guide filling block 1-5. Preferably, in order to ensure that the foaming material can flow quickly and be evenly distributed along the guide filling block 1-5, an extension portion 1-53' extending laterally is provided on the back side of the guide filling block 1-5, and a cushion block 1-52' is provided on the extension portion 1-53', and a notch structure 1-54' is also provided on the extension portion 1-53'. Specifically, during the foaming process, the foaming material flows along the back side of the guide filling block 1-5, and the foaming material can flow through the notch structure 1-54' to the front side of the guide filling block 1-5 and pass through the guide groove 1-51' to be evenly distributed around the inner liner 1-2 on both sides to achieve uniform distribution of the foaming material.

[0046] Based on the above technical solution, the foaming cabinet 1 can be assembled by the following method. The assembly method of the foaming cabinet 1 includes: first installing the crossbeam 10 on the inner liner 1-2, then assembling the outer shell 1-1, the middle beam 1-3 and the two inner liner 1-2 together to form a foaming cavity, and at the same time, placing a guide filling block 1-5 between the two inner liner 1-2, and finally injecting foaming material into the foaming cavity to form a foaming insulation layer in the foaming cavity. At the same time, the foaming material also flows into the crossbeam 10 and forms a foaming insulation layer in the gap between the shell 101 and the insulation filling block 102. Among them, for the outer shell 1-1 during assembly before foaming, the assembly method also includes installing the guide filling block 1-51-5 on the back of the middle beam 1-3 and placing it between the two inner liner 1-2. Specifically, first assemble the top plate 1-11, two side plates 1-12 and the bottom plate 1-13 together, then install the middle beam 1-3 between the top plate 1-11 and the bottom plate 1-13, then install the cabinet opening assembly between the middle beam 1-3, the top plate 1-11, the side plates 1-12 and the bottom plate 1-13, then install the guide filling block 1-5 between the two inner tanks 1-2, and finally, install the back plate 1-14 to form a foaming cavity.

[0047] By configuring the insulation filling block in the crossbeam, after foaming, the foamed material entering the crossbeam and the insulation filling block work together to insulate, and the insulation filling block can ensure that the crossbeam has sufficient insulation performance, avoiding the phenomenon of poor local insulation effect due to uneven distribution of the foamed material in the crossbeam. At the same time, the sheet metal decorative plate configured on the crossbeam can meet the requirements of door hinge installation strength, avoiding the deformation caused by directly installing the door body on the outer shell or liner, and improving the reliability of use.

[0048] Furthermore, in order to improve the space utilization and increase the storage volume in the foam cabinet 1, a press cavity 13 is formed on the top of the foam cabinet 1, and the condenser 15 and the compressor 14 are arranged in the press cavity 13, and a condensing fan 16 is arranged between the condenser 15 and the compressor 14. Specifically, the press cavity 13 is formed on the top of the foam cabinet 1 to install the compressor 14, the condenser 15 and the condensing fan 16. In this way, the press cavity 13 can fully utilize the top space of the foam cabinet 1, and the bottom space of the foam cabinet 1 can be fully utilized as the storage space 11, thereby effectively increasing the storage volume. At the same time, an air inlet 131 and an air outlet 132 are arranged on the back of the foam cabinet 1. On the one hand, the heat dissipation requirements of the press cavity 13 can be met. On the other hand, since the air inlet 131 and the air outlet 132 are arranged on the back of the foam cabinet 1, in actual use, express cabinets often have multiple side by side. The arrangement is such that even if other express cabinets are arranged on both sides of the foaming cabinet body 1, the normal circulation ventilation of the air inlet 131 and the air outlet 132 will not be affected. In order to avoid the mutual influence of the inlet and outlet air, the air inlet 131 is close to one side of the foaming cabinet body 1, and the air outlet 131 is close to the other side of the foaming cabinet body 1. In order to improve the waterproof performance, the air inlet 131 and the air outlet 132 are respectively provided with downward inclined water baffles. In this way, in a rainy environment, rainwater is blocked by the water baffles, which can reduce or avoid rainwater from entering the press cavity 13 through the air inlet 131 and the air outlet 132, thereby more effectively improving the waterproof performance. Furthermore, in order to achieve rapid assembly and disassembly, a removable mounting plate 130 is provided in the compressor cavity 13, and the compressor 14, the condenser 15 and the condensing fan 16 are arranged on the mounting plate 130. Specifically, in the actual assembly process, the compressor 14, the condenser 15 and the condensing fan 16 are first installed on the mounting plate 130, and then the compressor 14, the condenser 15 and the condensing fan 16 are uniformly installed on the top of the foaming cabinet 1 through the mounting plate 130, which simplifies the assembly process and reduces the difficulty of assembly. Furthermore, the back of the foam cabinet 1 is also provided with a waterproof wire tube 17 for arranging the power line and the signal line outside the foam cabinet 1. Specifically, the power line connected to the foam cabinet 1 is routed through the waterproof wire tube 17. Similarly, the communication line connected to the foam cabinet 1 is also routed through the waterproof wire tube 17. On the one hand, the waterproof wire tube 17 can provide waterproof protection for the power line and the communication line. On the other hand, the related wire harnesses located outside the foam cabinet 1 are all concentrated in the waterproof wire tube 17 for routing, making the wire harness more regular and improving user experience and reliability. Preferably, in order to make full use of the top space of the foam cabinet 1, for the express cabinet, a light box 18 is usually configured. In this way, the space occupied by the light box 18 can be utilized, and a partition 181 is provided in the light box 18. The partition 181 divides the light box 18 into a lighting cavity 180 and a press cavity 13 arranged front and back. The lighting cavity 180 is provided with a lighting lamp and an electric control box.Specifically, the space formed by the light box 18 is used to divide the interior of the light box 18 into a lighting cavity 180 and a press cavity 13 through a partition 181. High-voltage accessories such as lighting and an electric control box are placed on the front side of the light box 18 to prevent high-voltage electricity from being easily exposed, thereby ensuring safety in use. The condenser 15, the compressor 14 and the condensing fan 16 are placed on the back side of the light box 18 to effectively utilize the space of the light box 18.

[0049] Furthermore, for the evaporator 18, its installation method can adopt the installation method of the evaporator and the cabinet in the prior art, so that the evaporator 18 is arranged in the foam cabinet 1 to realize cooling the storage space 11. Preferably, each inner tank 1-2 is provided with an air duct cover plate 1-22, and an air duct is formed between the air duct cover plate 1-22 and the inner wall of the inner tank 1-2, and the evaporator 18 and the evaporation fan 19 are arranged in the air duct, and the air duct cover plate 1-22 is provided with an air outlet (not marked) in each storage space 11. Specifically, each inner liner 1-2 is respectively configured with an air duct cover 1-22 to form an independent air duct, so that air circulation can be performed independently in the corresponding inner liner 1-2, wherein the two evaporators 18 can be arranged in series or in parallel, and in order to increase the volume of the inner liner 1-2, an installation groove (unmarked) is formed on the back of the inner liner 1-2, and the evaporator 18 and the evaporation fan 19 are located in the installation groove. In this way, the impact of installing the evaporator 18 and the evaporation fan 19 in the inner liner 1-2 on the internal volume of the inner liner 1-2 can be reduced, so that the user can obtain the maximum volume of storage space.Among them, a return air outlet is provided at the bottom of the air duct for realizing return air.
