That is, under the external operation, the rotating mechanism 820 can rotate to the first position to lock and connect two adjacent storage modules, and can also rotate to the second position to release the connection between two adjacent storage modules. By adopting the technical scheme of the invention, the storage modules can be simply and conveniently disassembled and assembled by only one person, the operation is simple and labor-saving, and the reliable firmness and tightness of the connection of the two adjacent storage modules can be ensured, so that the sealing effect between the two adjacent storage modules is enhanced, particularly the sealing effect of the connection between the air ducts of the two storage modules is better avoided, and the refrigeration effect and the refrigeration efficiency of the refrigerating and freezing device 1 are improved.
Further, because two adjacent storage modules are detachably connected, the number of the storage modules and the type and the arrangement mode of the storage modules are changed according to actual needs of users, and the electricity diversification needs of the users are met.
It is emphasized that in the embodiment shown in fig. 4, the first direction M may be a clockwise direction, and in this case, the second direction N is a counterclockwise direction. In other embodiments of the present invention, the first direction may also be a counterclockwise direction, and in this case, the second direction is a clockwise direction.
Fig. 5 is a further schematic exploded view of a rotary locking device according to one embodiment of the present invention, and fig. 6 is a schematic cross-sectional view of a rotary locking device according to one embodiment of the present invention. In some embodiments of the present invention, the rotating mechanism 820 includes an eccentric 821 and a rotating shaft 822 passing through the axis of the eccentric 821 and forming a fit with the eccentric 821, wherein the rotating shaft 822 is operable to rotate in the first direction M or the second direction N to drive the eccentric 821 to rotate synchronously.
Specifically, the eccentric wheel 821 is a wheel body with an axis offset from the geometric center thereof, and has a regular or irregular shape. The cross-section of the rotating shaft 822 has the same shape as the axial center of the eccentric 821 so that the rotating shaft 822 is in form-fitting connection with the eccentric 821. Preferably, in one embodiment of the present invention, the axial center of the eccentric wheel 821 and the cross section of the rotating shaft 822 are pentagonal. In alternative embodiments of the present invention, the axial center of the eccentric 821 and the cross-section of the rotating shaft 822 may each have a triangular, square, or other suitable shape.
In some embodiments of the invention, at least part of the circumferential edge of the eccentric 821 is provided with two rings of closed or semi-closed rims 823 which respectively project towards both sides of the eccentric 821 in the axial direction of the eccentric 821. The locking mechanism 810 has two locking bosses 811 for snap-fitting engagement with two flanges 823 of the cam 821, respectively, when the cam 821 is rotated to the first position. Specifically, each locking boss 811 has an arcuate upper surface and each ledge 823 has an arcuate outer surface, the arcuate outer surface of each ledge 823 gripping the upper surface of the corresponding locking boss 811 when the cam 821 is rotated to the first position.
It should be emphasized that the closed state in the present invention means that the two ends of the protruding edge 823 are connected end to end, i.e. forming a closed ring shape with a regular or irregular shape, and the semi-closed state in the present invention means that the two ends of the protruding edge 823 are at different positions, i.e. the two ends of the protruding edge 823 are not enclosed together, forming a non-closed semi-ring shape.
Further, the outer surface of every protruding 823 along all is equipped with evenly distributed's pit to increase protruding 823 and lock the frictional force between the boss 811, thereby strengthened rotation type locking device 80's reliability, and then improved the steadiness of connecting between two adjacent storing modules.
In some embodiments of the present invention, the eccentric wheel 821 has two wheels 8211 disposed symmetrically and engaged with each other, and two convex edges 823 are respectively disposed on the circumferential edges of the two wheels 8211. Further, the two rims 823 may be symmetrically disposed.

In some embodiments of the present invention, the rotating mechanism 820 further includes an operating portion 825 coaxially and fittingly connected to the rotating shaft 822 to rotate the rotating shaft 822 synchronously. Specifically, the rotation shaft 822 may be a hollow shaft having a hollow inside. The operation portion 825 has an end cap and a connection rod, which is inserted inside the rotation shaft 822. The outer surface of the rotation shaft 822 is coupled to the eccentric 821 in a form-fitting manner, and the inner surface is coupled to the coupling rod of the operating part 825 in a form-fitting manner.
In some embodiments of the present invention, the locking mechanism 810 and the rotation mechanism 820 comprise a housing 813 and a housing 827, respectively, disposed at the mating edge portions of two adjacent storage modules, each housing defining a receiving cavity therein. The first guide plate 812 and the two locking bosses 811 are received in the receiving cavity of the housing 813, and the eccentric 821, the rotational shaft 822, the flange 823, the stopper 824, and the second guide plate 826 are received in the receiving cavity of the housing 827. The operation portion 825 of the rotating mechanism 820 is exposed outside the peripheral wall of one of the storage modules, so that a user can rotate the operation portion 825 as required.
Fig. 7 is an exploded schematic block diagram of a base layer storage module and a second layer storage module according to an embodiment of the invention. In some embodiments of the present invention, two adjacent storage modules are positioned by two pin hole mechanisms 830 in a diagonal direction. Each pin hole mechanism includes a positioning pin 831 and a positioning hole 832 respectively disposed on the mating interface of two adjacent storage modules, thereby ensuring the positioning accuracy and stability between the two storage modules with a simple and small number of positioning structures.
Further, in the depth direction of the refrigerating and freezing device 1, the distance from the more rear pin hole mechanism to the rear surface of any storage module in the two pin hole mechanisms is smaller than the distance from the more front pin hole mechanism to the front surface of any storage module, so that the positioning between the two storage modules is more accurate.
In some embodiments of the present invention, the locking mechanism 810 further includes two first guide plates 812 disposed opposite to each other, and two locking bosses 811 are formed on two opposite surfaces of the two first guide plates 812, respectively. The rotating mechanism 820 further includes two second guide plates 826 disposed opposite to each other, the eccentric wheel 821 and the rotating shaft 822 are located between the two second guide plates 826, and the operating part 825 passes through the second guide plates 826 located at the outside to be coupled to the rotating shaft. The space between the two first guide plates 812 and the space between the two second guide plates 826 form a motion track of the eccentric 821 to guide the eccentric 821 to rotate, preventing the eccentric 821 from tilting during rotation.
Furthermore, the two adjacent storage modules can be further firmly connected through structures such as screws.
Specifically, the locking mechanism 810 may be disposed at a lower portion of an upper storage module of two adjacent storage modules, and the rotating mechanism 820 may be disposed at an upper portion of a lower storage module. The locking mechanism 810 may be received in a receiving cavity of an upper storage module, and the eccentric 821 and the rotating shaft 822 of the rotating mechanism 820 may be received in a receiving cavity of a lower storage module. The locating pin 831 of the pin and hole mechanism 830 is disposed on the top surface of the lower storage module and the locating hole 832 of the pin and hole mechanism 830 is disposed on the bottom surface of the upper storage module.
In some embodiments of the invention, the refrigerated freezing apparatus 1 further comprises a refrigeration module 10 for providing a cooling airflow to at least two of its storage modules. Each storage module is provided with an air supply duct for supplying cooling airflow into the storage space of the storage module and a return air duct for supplying return air in the storage space of the storage module to the refrigeration module 10 directly or indirectly. The air supply channels and the air return channels of the two adjacent storage modules are connected in a matched mode through wedge-shaped grooves and wedge-shaped bulges, and sealing gaskets are arranged between the wedge-shaped grooves and the wedge-shaped bulges so as to form airtight sealing between the wedge-shaped grooves and the wedge-shaped bulges. The wedge-shaped connecting mode can better avoid generating gaps or air leakage, so that good airtight sealing can be formed between the air supply channels and between the air return channels of the two storage modules. Meanwhile, the gap possibly existing between the wedge-shaped groove and the wedge-shaped bulge can be filled through elastic deformation of the sealing washer, so that the sealing and leakage-proof effects are achieved, and the airtight sealing between the upper storage module and the lower storage module is enhanced.
Specifically, in the embodiment shown in fig. 1, the refrigeration and freezing device 1 includes three storage modules, namely, a base storage module 20, a second storage module 30 and a third storage module 40, which are sequentially arranged from bottom to top. Fig. 8 is a schematic sectional view taken along a sectional line B-B in fig. 3, and fig. 9 is a schematic enlarged view of a portion a in fig. 8. In particular, the refrigeration module 10 is hidden in fig. 8.
Taking the connection between the air supply ducts of the third layer of storage modules 40 and the second layer of storage modules 30 as an example, referring to fig. 9, the third layer of storage modules 40 has a fourth level air supply duct 411, and the second layer of storage modules 30 has a third level air supply duct 311. Fourth level air supply duct 411 and third level air supply duct 311 are connected in a matched manner through a wedge-shaped groove 4111 arranged at the top opening of fourth level air supply duct 411 and a wedge-shaped protrusion 3111 arranged at the bottom of third level air supply duct 311, and a sealing gasket 32 is arranged between wedge-shaped groove 4111 and wedge-shaped protrusion 3111.
Fig. 10 is an exploded schematic block diagram of a refrigeration module and a substrate storage module according to an embodiment of the invention, and fig. 11 is another schematic orientation of fig. 10. In some embodiments of the present invention, the refrigeration module 10 is disposed below at least two of the storage modules and is removably coupled to the lowermost substrate storage module 20. The top of refrigeration module 10 is open and the bottom of base storage module 20 is open. That is, the refrigeration module 10 does not have a relatively independent top panel and the base storage module 20 does not have a relatively independent bottom panel.
A reusable wall panel 60 is provided between refrigeration module 10 and base storage module 20, reusable wall panel 60 being configured to be reused on the top panel of refrigeration module 10 and the bottom panel of base storage module 20 to simultaneously enclose the top of refrigeration module 10 and the bottom of base storage module 20 and allow a fluid connection between refrigeration module 10 and the base storage module. That is, the cooling air flow generated by refrigeration module 10 may flow to substrate storage module 20 and the return air within substrate storage module 20 may flow to refrigeration module 10. That is, the top panel of the refrigeration module 10 is integral with the bottom panel of the base storage module 20. Therefore, the height of the refrigeration module 10 is reduced (the reduced height is approximately 50-100 mm), and the reduced partial space can be used for increasing the thickness of the heat insulation layer between the refrigeration module 10 and the base storage module 20, so that the heat insulation performance is enhanced.
Further, the refrigeration and freezing device 1 of the present invention reduces the top plate at the top of the refrigeration module 10, reduces the matching components, and enhances the sealing performance of the evaporator chamber of the refrigeration module 10, thereby reducing the cold leakage phenomenon of the evaporator chamber and achieving the purpose of energy saving.
Further, the refrigeration and freezing device 1 of the present invention reduces the top plate at the top of the refrigeration module 10, and after the top plate is integrated with the bottom plate of the base storage module 20, the fixing screws for the top plate and the evaporator chamber, the metal casing of the base storage module 20, and the like can be eliminated, thereby simplifying the structure of the refrigeration and freezing device 1 and reducing the cost.
Further, since the base storage module 20 is attached above the refrigeration module 10, that is, the base storage module 20 is detachably connected to the refrigeration module 10, a user can detach the refrigeration module 10 or replace the base storage module 20 according to the actual need thereof, which facilitates the maintenance of the refrigeration module 10 and the replacement of the type of the base storage module 20, thereby satisfying the diversified demands of the user.
In some embodiments of the present invention, the refrigeration module 10 has a refrigeration system for providing a cooling airflow, a primary supply air duct 111 for supplying the cooling airflow generated by the refrigeration system to the at least two storage modules, and a primary return air duct 112 for supplying return air from the at least two storage modules to the refrigeration system. The refrigeration system of the refrigeration module 10 includes an evaporator box assembly 120, the evaporator box assembly 120 having a box 121 and an evaporator 122 disposed within the box 121. The interior of the box 121 forms the evaporator chamber of the refrigeration module 10 and the evaporator 122 is adapted to exchange heat with the airflow passing therethrough to form a cooled airflow. The air flow in heat exchange relationship with the evaporator 122 includes return air from the substrate storage module 20 or other storage module into the refrigeration module 10 and/or ambient air from the environment in which the evaporator 122 is located.
Further, a primary supply air duct 111 and a primary return air duct 112 are formed inside the case 121 to supply return air to the evaporator 122 and to send the cooled air flow generated by the evaporator 122 out of the evaporator compartment.

That is, the first cavity 63 is opposed to at least a partial region of the case 121 in the up-down direction to cover most of the region of the case cutout 1211 except for the top openings of the primary supply air duct 111 and the primary return air duct 112, particularly the region corresponding to the evaporator 122.
The first insulating member 65 in the first cavity 63 may serve as an additional insulating layer to insulate heat transfer between the evaporator chamber and the substrate storage module 20, thereby improving the insulating effect of the various modules of the refrigeration and freezing apparatus 1. At least part of the outer peripheral wall of the first cavity 63 abuts against the peripheral edge of the notch 1211, which is equivalent to the first cavity 63 being plugged into the notch 1211, and the matching area between the notch 1211 and the multiplexing wall plate 60 for closing the notch 1211 is increased, so that air leakage can be better prevented, and the sealing effect of the notch 1211 and the refrigerating efficiency of the refrigerating and freezing device 1 are improved.
The front part of the reusable wall plate 60 is provided with a second concave cavity 64 which is concave downwards, the bottom wall of the second concave cavity 64 protrudes downwards from the lower surface 60a of the reusable wall plate 60, the outer peripheral wall of the rear part of the second concave cavity 64 is abutted against the forward surface of the box body 121, and a second heat-insulating part 66 is arranged in the second concave cavity 64.
Specifically, the refrigeration system of the refrigeration module 10 also includes a compressor 131 and a condenser 132 located on the front side of the evaporator box assembly 120. The second cavity 64 is substantially opposite to the area where the compressor 131 and the condenser 132 are located in the up-down direction to cover the area. The compressor 131 and the condenser 132 generate a certain amount of heat during operation, and the second thermal insulation member 65 disposed in the second cavity 64 can isolate the heat transfer between the region where the compressor 131 and the condenser 132 are located and the substrate storage module 20, so as to prevent the heat generated by the compressor 131 and the condenser 132 from affecting the storage environment of the substrate storage module 20, and enhance the thermal insulation performance of the substrate storage module 20.
Further, a fourth thermal insulation member 142 is disposed between the condenser 132 and the multiplexing wall 60, and a third thermal insulation member may be disposed between the compressor 131 and the multiplexing wall 60, so as to further ensure that no heat transfer occurs between the region where the compressor 131 and the condenser 132 are located and the substrate storage module 20. Specifically, a third insulating member may be disposed between the compressor 131 and the bottom wall of the second cavity 64, and a fourth insulating member 142 may be disposed between the condenser 132 and the bottom wall of the second cavity 64.
In some embodiments of the present invention, the box 121 may be made of a material having a thermal insulation function to prevent the evaporator chamber therein from exchanging heat with the compressor 131 and the condenser 132, so as to prevent the heat generated by the compressor 131 and the condenser 132 from affecting the temperature in the evaporator chamber. An insulation member may be additionally disposed between the region where the compressor 131 and the condenser 132 are located and the case 121.
Figure 12 is a schematic exploded structural view of a refrigeration module according to one embodiment of the present invention. In some embodiments of the invention, the refrigeration module 10 further includes a rack 150 for supporting the base storage module 20 and a bottom support plate 160 for supporting the evaporator box assembly 120, the compressor 131, and the condenser 132. The frame 150 is hollow inside and has a skeleton 154, a front shelf 151, a rear shelf 152, and two side shelves 153. The evaporator box assembly 120, the compressor 131 and the condenser 132 are all disposed inside the rack 150. The areas of the two side frame plates 153 corresponding to the compressor 131 and the condenser 132, respectively, are opened with vent holes so that heat generated from the compressor 131 and the condenser 132 is timely dissipated into the ambient space.
In some embodiments of the invention, the base storage module 20 has a secondary supply air duct 211 for the flow of cooling air into its storage space and a secondary return air duct 212 for the flow of return air from its storage space to the refrigeration module 10.
The evaporator box assembly 120 is configured to be vertically movable relative to the bottom support plate 160 of the refrigeration module 10 to sealingly communicate the primary supply air duct 111 and the primary return air duct 112 with the secondary supply air duct 211 and the secondary return air duct 212, respectively, when the evaporator box assembly 120 is moved upwardly, and to disconnect the primary supply air duct 111 and the primary return air duct 112 from the secondary supply air duct 211 and the secondary return air duct 212, respectively, when the evaporator box assembly 120 is moved downwardly, thereby separating the evaporator box assembly 120 from the base storage module 20. On one hand, the evaporator box assembly 120 can be pressed against the base storage module 20 by the upward movement thereof, so as to ensure that each air channel of the evaporator box assembly 120 is in good sealing connection with the corresponding air channel of the base storage module 20, thereby solving the technical problems that the combined refrigerating and freezing device (such as a combined refrigerator) always exists and the technical problem that a person skilled in the art always desires to solve but does not always successfully solve; on the other hand, complete separation between the evaporator box assembly 120 and the base storage module 20 is also achieved by the downward movement of the evaporator box assembly 120, so that the refrigeration module 10 can be independently disassembled without structural interference to facilitate servicing of the refrigeration module 10.
Specifically, the multiplexing wall 60 is provided with an air supply through hole 61 for hermetically communicating the primary air supply duct 111 and the secondary air supply duct 211, and a return air through hole 62 for hermetically communicating the primary return air duct 112 and the secondary return air duct 212. The supply air through-hole 61 may be formed in the bottom wall of the first cavity 63, and the return air through-hole 62 may be formed outside the first cavity 63.
In some embodiments of the present invention, the refrigeration module 10 further includes a lift mechanism 180 disposed on the bottom support plate 160, the lift mechanism 180 configured to operatively raise and/or lower the evaporator box assembly 120 to move the evaporator box assembly 120 in a vertical direction relative to the bottom support plate 160. In some alternative embodiments, the evaporator box assembly 120 can also be raised and/or lowered manually or by other suitable means.
Further, the elevating mechanism 180 includes at least one elevating unit, each of which includes: a top press block 181 for pressing the bottom of the evaporator box assembly 120; a lever 182 is pivotally supported on the bottom support plate 160 and has a resistive end pivotally connected to the jacking block 181 to operatively raise and/or lower the jacking block 181 to raise and/or lower the evaporator pan assembly 120 using the principles of a lever.
Further, each lifting unit further comprises: a pressing portion 183 configured to operatively press down on the power-acting end of the lever 182 to raise the evaporator box assembly 120 via the resistance-acting end of the lever 182 and/or to operatively release the power-acting end of the lever 182 to lower the evaporator box assembly 120.
Further, the lifter mechanism 180 also includes a bottom block 184 that is configured to be seated on the bottom of the evaporator box assembly 120 after the evaporator box assembly 120 is raised to a predetermined height so that the evaporator box assembly 120 remains in a predetermined height position.
Specifically, the pressing portion 183 may be a rod-shaped member having one end coaxially connected to the power-acting end of the lever 182. Each lifting unit further includes an adjusting lever 185 selectively connected to both the pressing part 183 and the lever 182. When the adjusting lever 185 is simultaneously coupled to the pressing part 183 and the lever 182 (i.e., when the adjusting lever 185 sequentially passes through the pressing part 183 and the fixing hole of the lever 182), the pressing part 183 is fixedly coupled to the lever 182, and the power acting end of the lever 182 is synchronously rotated with the rotation of the pressing part 183. When the adjustment lever 185 is not coupled to the pressing part 183 and the lever 182 (i.e., when the adjustment lever 185 is withdrawn from the pressing part 183 and the fixing hole of the lever 182), the pressing part 183 may rotate with respect to the lever 182.
In the normal state, the pressing portion 183 is in a vertically placed state. When it is desired to lift the evaporator box assembly 120, the adjustment lever 185 is first connected to both the pressure applying section 183 and the lever 182; then, the pressing part 183 is rotated outwards, so that the lever 182 is driven to rotate, the top pressing block 181 is lifted, and the evaporator box lifting assembly 120 is lifted to a preset height position through the top pressing block 181; the bottom pad 184 is finally pushed into the bottom of the evaporator box assembly 120 to maintain it in this height position. In order to prevent the outwardly rotated pressing part 183 from occupying an excessive space, the adjustment lever 185 may be withdrawn from the fixing holes of the pressing part 183 and the lever 182, and the pressing part 183 may be inwardly rotated to be restored to the upright state.
Further, the number of lifting units may be two, with the two lifting units being symmetrically disposed on either side of the bottom of the evaporator box assembly 120. In order to achieve the synchronous lifting of the two lifting units to ensure the stability of the evaporator box assembly 120, the pressing blocks 181 and the pressing portions 183 of the two lifting units may be connected by a laterally extending connecting rod, respectively.
In alternative embodiments of the present invention, the lifting mechanism 180 can also be other mechanisms capable of lifting and lowering the evaporator box assembly 120. For example, the lifting mechanism 180 may be a mechanism composed of a plurality of wedge-shaped blocks and an operating portion, a mechanism composed of at least one wedge-shaped block and a thrust rod, a mechanism formed by a rotatable supporting crankshaft, a mechanism formed by using a lever principle, a mechanism composed of a top pressure plate and a connecting rod, a mechanism composed of a worm gear transmission mechanism and a top pressure plate, a mechanism composed of a double-pressure screw and a nut, a cam mechanism, a mechanism composed of a top pressure plate, a screw rod and a connecting rod, and the like.

In some embodiments of the present invention, the third-level storage module 40 is attached above the second-level storage module 30, and has a fourth-level air supply duct 411 in sealed communication with the third-level air supply duct 311 of the second-level storage module 30, so that part of the cooling air flow provided by the refrigeration module 10 flows to the storage space of the third-level storage module 40 through the primary air supply duct 111 of the refrigeration module 10, the secondary air supply duct 211 of the base-level storage module 20, the third-level air supply duct 311 of the second-level storage module 30, and the fourth-level air supply duct 411 of the third-level storage module 40 in sequence.
Further, the third storage module 40 further has a fourth-stage return air duct 412, which can be in sealed communication with the third-stage return air duct 311 of the second storage module 30 and also in sealed communication with the secondary return air duct 212 of the base storage module 20, as long as the return air in the third storage module 40 can return to the refrigeration module 10 to participate in heat exchange.
It is emphasized that when the refrigerated freezer 1 has only base and third tier storage modules 20, 40, the third tier storage module 40 may be attached directly above the base tier storage module 20.
In some embodiments of the present invention, the base layer storage module 20 includes a cabinet 220 having a storage space and a door 230 pivotably coupled to a front side of the cabinet 220 to open and/or close the storage space through the door 230. The height at which the door body 230 extends in the vertical direction is configured such that the door body 230 covers the front sides of the cabinet 220 and the refrigeration module 10 when in the closed state. That is, the height of the door 230 of the base storage module 20 in the vertical direction is substantially the same as the sum of the height of the cabinet 220 of the base storage module 20 and the height of the refrigeration module 10. Therefore, the user can be prevented from directly seeing the refrigeration module 10 from the appearance, and the whole appearance of the refrigeration and freezing device 1 is ensured.
In one embodiment of the present invention, the temperature in the storage space of the substrate storage module 20 can be controlled within a range of-26 ℃ to-10 ℃ so as to have a frozen storage environment; the temperature in the storage space of the second layer of storage modules 30 can be controlled within the range of-18 ℃ to 5 ℃ so as to provide a variable storage environment; the temperature in the storage space of the third storage module 40 can be controlled within the range of 0-8 ℃, so that the third storage module has a refrigerated storage environment. That is, the base storage module 20, the second storage module 30, and the third storage module 40 may be a freezing module, a temperature changing module, and a refrigerating module, respectively. Of course, the storage environments of the base storage module 20, the second storage module 30, and the third storage module 40 may all be different according to the user's choice.
In some embodiments of the present invention, the refrigeration freezer 1 may further include a top cover 50 disposed on top. The top cover 50 is removably coupled to the uppermost storage module. That is, when the refrigerating and freezing device 1 has only the base storage module 20, the top cover 50 is detachably connected to the base storage module 20; when the refrigeration and freezing device 1 has two storage modules, namely the base storage module 20 and the second storage module 30, the top cover 50 is detachably connected with the second storage module 30; when the refrigerating and freezing device 1 has three storage modules, namely, the base storage module 20, the second storage module 30 and the third storage module 40, the top cover 50 is detachably connected to the third storage module 40.
Further, in order to ensure that other storage modules can be attached above the uppermost storage module, the top of each storage module is provided with an air duct opening. The underside of the top cover 50 is provided with a wedge-shaped sealing mechanism for mating with the corresponding air vents of the uppermost storage module to form an air-tight seal between the top cover 50 and the uppermost storage module. The wedge-shaped form fit connection mode can better avoid generating gaps or air leakage, namely the sealing effect of the wedge-shaped sealing mechanism is better.
Further, the top cover 50 is a plate-shaped member made of a heat insulating material to form an additional heat insulating layer on the top of the refrigerating and freezing device 1, thereby enhancing the heat insulating effect of the refrigerating and freezing device 1. Specifically, the top cover 50 has a certain thickness to ensure its heat-insulating effect. The top cover 50 may be a VIP panel made of VIP insulating material.
In some embodiments of the invention, an elastic gasket is arranged between two adjacent storage modules, and the elastic gasket is compressed under the gravity of the storage module above the elastic gasket so that the internal space of the elastic gasket forms a compressed air heat insulation layer. The heat transfer coefficient of air is lower, can realize insulating against heat between two storing modules better, avoids two storing modules direct rigid contact to cause surface damage simultaneously. In addition, after the elastic gasket is compressed, elastic expansion deformation can occur so as to enable the connection of the two modules to be more firm. In particular, the elastic washer may be made of a rubber material or other elastic material.
