Detailed Description

The embodiment of the invention provides a refrigeration module for a refrigeration and freezing device, which is also provided with at least one storage module for storing articles, wherein a storage space is defined in each storage module. Fig. 1 is a schematic structural view of a refrigeration module for a refrigerator freezer according to one embodiment of the present invention, and fig. 2 is a schematic structural exploded view of a refrigeration module for a refrigerator freezer according to one embodiment of the present invention. Referring to fig. 1 and 2, the refrigeration module 10 includes an evaporator box assembly 100 and a bottom support plate 200. The top of the evaporator box assembly 100 has a supply air opening 111 for the flow of air therein and a return air opening 112 for the flow of external air. The number of the air-returning openings 112 may be one or more. The bottom support plate 200 is used to carry the evaporator box assembly 100. Specifically, the evaporator box assembly 100 can include a box body 110, an evaporator and a blower (not shown) disposed within the box body 110. The air supply opening 111 and the air return opening 112 are both opened on the top wall of the box body 110 so as to convey cooling air after heat exchange through the evaporator to the storage module located above the refrigeration module 10 through the air supply opening 111, and return air from the storage module can return to the inside of the box body 110 through the air return opening 112 so as to exchange heat with the evaporator. The blower is used to cause an airflow to circulate between the interior of the refrigeration module 10 (which may be specifically the interior of the evaporator box assembly 100) and the exterior (which may be, for example, a storage module). The fan may be disposed above the evaporator so that an air outlet of the fan is opposite to the air supply outlet 111, and thus the cooling airflow after heat exchange flows out of the refrigeration module 10 as soon as possible, thereby avoiding turbulence, mixed flow and the like in the box body 110.

In particular, the refrigeration module 10 also includes a lift mechanism having at least one lift unit 310 located below the evaporator box assembly 100. Fig. 3 is a schematic structural view of a lifting unit of a refrigeration module according to one embodiment of the present invention, and fig. 4 is a schematic structural exploded view of the lifting unit of the refrigeration module according to one embodiment of the present invention. Referring to fig. 3 and 4, each of the lifting units 310 includes: at least one wedge block set, each wedge block set comprising a fixed wedge block 311 fixed to the bottom of the evaporator box assembly 100 and a movable wedge block 312 movably disposed on the bottom support plate 200, the movable wedge block 312 cooperating with the fixed wedge block 311 through a wedge surface; and an operating mechanism 313 configured to operatively move the movable wedge 312 over the bottom support plate 200 to vertically move the fixed wedge 311 with the movement of the movable wedge 312 to raise and/or lower the evaporator box assembly 100 and to sealingly communicate its supply and return air inlets with respective air channels of a storage module disposed adjacent above the refrigeration module 10 when the evaporator box assembly 100 is raised and to separate the evaporator box assembly 100 from the storage module when lowered. Specifically, each storage module has an air supply duct through which cooling air flows into its storage space and an air return duct through which air in its storage space returns to the refrigeration module 10. When the evaporator box assembly 100 is raised to a certain height, the supply air outlet 111 can be in sealed communication with the supply air duct of the storage module located above the refrigeration module 10 and adjacent to the refrigeration module 10, and the return air outlet 112 can be in sealed communication with the return air duct of the storage module, so as to prevent the air flow from leaking.

The evaporator box assembly 100 is lifted and/or lowered by the lifting mechanism, on one hand, the evaporator box assembly 100 can be lifted upwards to be tightly pressed on the storage module, and the air opening of the evaporator box assembly 100 is ensured to be in good sealing connection with the storage module; on the other hand, complete separation between the refrigeration module 10 and the storage module can be achieved by the falling evaporator box assembly 100, so that the refrigeration module 10 can be independently disassembled without structural interference, and thus, the refrigeration module 10 can be conveniently overhauled.

Further, the upper portion of the evaporator box assembly 100 may be provided with a gasket around at least the air supply opening 111 and the air return opening 112 to further ensure good air tightness between the refrigeration module 10 and the storage module.

In some embodiments of the present invention, in each lifting unit 310, the number of wedge-block sets is two, and the two fixed wedge blocks 311 of the two wedge-block sets and the two movable wedge blocks 312 of the two wedge-block sets are symmetrically arranged. That is, the two fixed wedges 311 are symmetrically disposed, and the two movable wedges 312 are symmetrically disposed. The operating mechanism 313 is configured to be movably disposed between the two movable wedges 312 to cause the two movable wedges 312 to move synchronously away from and/or toward each other to raise and/or lower the evaporator box assembly 100 via the two fixed wedges 311. Specifically, the operating mechanism 313 can be moved by the same amount to cause the two movable wedges 312 to move in the same distance to ensure that the two fixed wedges 311 move in the same vertical direction to make the evaporator box assembly 100 more stable.

That is, the two fixed wedges 311 can provide two support points for the evaporator box assembly 100 to prevent the evaporator box assembly 100 from tilting during lifting and lowering. Further, the two movable wedges 312 moving away from and/or toward each other synchronously ensure that the two fixed wedges 311 move synchronously in the vertical direction, i.e., the two fixed wedges 311 are always at the same height during the lifting and/or lowering of the evaporator box assembly 100, further ensuring the smoothness of the lifting and lowering process of the evaporator box assembly 100.

In some embodiments of the invention the movable wedge block 312 has a first wedge-face 3121 extending obliquely upwards from its lower end to its upper end and a second wedge-face 3122 extending obliquely from one lateral end to its other lateral end, the second wedge-face 3122 lying in a vertical plane diagonally opposite the first wedge-face 3121. The first wedge-surface 3121 of the movable wedge block 312 cooperates with the wedge-surface of the fixed wedge block 311 and the second wedge-surface 3122 of the movable wedge block 312 cooperates with the operating mechanism 313 to ensure that the two movable wedge blocks 312 and the two fixed wedge blocks 311 can move synchronously.

In some embodiments of the invention, the operating mechanism 313 comprises an active wedge block 3131 having two symmetrical wedge surfaces extending obliquely away from each other from a first end of the active wedge block 3131 to a second end thereof and cooperating with the second wedge surfaces 3122 of the two movable wedge blocks 312, respectively. The active wedge 3131 is operable to move in a direction parallel to a horizontal extension from its first end to its second end to cause the two movable wedges 312 to move synchronously in a direction away from and/or towards each other.

Specifically, when the active wedge 3131 moves in a direction extending horizontally from its first end to its second end, the two movable wedges 312 move synchronously towards each other; the two fixed wedges 311 move synchronously downward under the force of gravity of the evaporator box assembly 100 and the fixed wedges 311 to drop the evaporator box assembly 100. Conversely, when the active wedge 3131 is moved in a direction extending horizontally from its second end to its first end, the two movable wedges 312 move synchronously in a direction away from each other, thereby pressing against the two fixed wedges 311, causing them to move synchronously upward, thereby lifting the evaporator box assembly 100. Therefore, the lifting mechanism is simple in structure, convenient to operate and reliable in adjustment.

The first end and the second end of the active wedge 3131 each have an end surface extending in a vertical direction, the end surfaces of the first end and the second end are two planes parallel to each other, and the width of the end surface of the first end is smaller than that of the end surface of the second end. The two wedge surfaces of the active wedge block 3131 are respectively connected to the ends of the active wedge block on the same side of the first and second end surfaces thereof, and are respectively abutted to the second wedge surfaces 3122 of the two movable wedge blocks 312. The active wedge 3131 is operable to move in a direction perpendicular to the first and second end faces thereof, thereby pushing the two movable wedges 312 to move by their two wedge faces, respectively.

In some embodiments of the present invention, the operating mechanism 313 further includes a screw 3132 rotatably supported on the bottom support plate 200, an axial direction of the screw 3132 being parallel to a direction horizontally extending from a first end of the active wedge 3131 to a second end thereof, the active wedge 3131 being disposed on the screw 3132 and configured to translate in an axial direction of the screw 3132 as the screw 3132 rotates. That is, the lead screw 3132 may be supported by the bracket 314 fixed to the bottom support plate 200. The bracket 314 allows only the screw 3132 to rotate in a vertical plane, but not the screw 3132 to displace in a horizontal plane. That is, the position of the lead screw 3132 with respect to the bottom support plate 200 remains unchanged. When it is desired to drop the evaporator box assembly 100, the screw 3132 can be rotated in a direction (e.g., counterclockwise), and the active wedge 3131 can be translated in a direction that causes the screw 3132 to rotate out of the movable wedge 312, i.e., the active wedge 3131 can be translated in a horizontal direction extending from its first end to its second end. When it is desired to raise the evaporator box assembly 100, the screw 3132 can be rotated in the opposite direction (e.g., clockwise), and the active wedge 3131 can translate in a direction that causes the screw 3132 to screw into the movable wedge 312, i.e., the active wedge 3131 can translate in a horizontal direction extending from its second end to its first end.

Specifically, the screw 3132 extends in a direction perpendicular to the first and second end faces of the active wedge 3131. In one embodiment of the present invention, the active wedge 3131 may have a threaded hole extending horizontally from a first end to a second end thereof, the screw 3132 has a thread matching the threaded hole of the active wedge 3131, and the active wedge 3131 and the screw 3132 are directly connected by the thread. In an alternative embodiment of the present invention, the screw 3132 may further be threaded with a nut, the active wedge 3131 is fixed on the nut, and the active wedge 3131 and the screw 3132 are indirectly connected through the nut. The screw nut translates axially with respect to the screw 3132, which drives the active wedge 3131 to translate.

That is, the screw 3132 and the active wedge 3131 may be directly or indirectly connected through a thread, so that when the screw 3132 stops rotating, the screw 3132 and the active wedge 3131 may remain relatively stationary, i.e., no slippage occurs between the screw 3132 and the active wedge 3131. In other words, when the screw 3132 stops rotating, the active wedge 3131, the movable wedge 312, and the fixed wedge 311 can all be positioned in a position that enables self-locking of the lifting mechanism, thereby keeping the evaporator cassette assembly 100 at a set height, simplifying the installation and removal operations of the refrigeration module 10.

It is emphasized that the lead screw 3132 is inserted into the active wedge 3131 to a different extent, as is the height at which the evaporator box assembly 100 is raised, i.e., the height of the evaporator box assembly 100 is adjustable depending on the extent to which the lead screw 3132 is rotated, whereby the refrigeration module 10 of the present invention is adaptable to a variety of different types or models of refrigerated freezers.

Further, an operating handle 3133 is connected to an end of the screw 3132 exposed to the outside to drive the screw 3132 to rotate, so as to drive the active wedge 3131 to translate. The operating handle 3133 and the screw 3132 may be fixedly connected by welding, clamping, or the like, or may be integrally formed.

In some embodiments of the present invention, the active wedge 3131 is provided with a through groove at a central position of a bottom thereof, which is upwardly recessed and extends from a first end of the active wedge 3131 to a second end thereof. That is, the through slot extends in a direction perpendicular to the first and second end faces of the active wedge 3131. The extending direction of the through groove is the same as the axial direction of the screw rod 3132 and the extending direction of the threaded hole of the active wedge block 3131.

Further, each lifting unit 310 further includes a limiting strip 315 disposed on the bottom supporting plate 200, and the limiting strip 315 is inserted into the through groove of the active wedge block 3131, so that the active wedge block 3131 moves along the limiting strip 315, thereby preventing the active wedge block 3131 from deflecting during the movement.

In some embodiments of the present invention, two sliding rails 316 are further disposed on the bottom support plate 200 and located at two lateral sides of the first wedge-shaped surface 3121 of the movable wedge-shaped block 312, and the movable wedge-shaped block 312 is disposed between the two sliding rails 316 to slide along the sliding rails 316 under the driving of the operating mechanism 313, so as to prevent the movable wedge-shaped block 312 from being deflected during the moving process.

In some embodiments of the present invention, the number of the lifting units 310 may be one, and the lifting units 310 may be disposed at the bottom center position of the evaporator box assembly 100 to provide a smooth support for the evaporator box assembly 100.

In some embodiments of the present invention, referring to fig. 1 and 2, the refrigeration module 10 further comprises at least one guide mechanism 330, each guide mechanism 330 being fixed to the bottom support plate 200 and having a guide 331 extending in a vertical direction. The evaporator box assembly 100 is configured to move in a vertical direction along the guide 331 during lifting and/or lowering. Interference or friction of the evaporator box assembly 100 with other structures during lifting and/or lowering can thereby be avoided, while also avoiding to some extent large deflections of the evaporator box assembly 100 during lifting and/or lowering. The number of the guiding portions 331 may be one or more, so as to further ensure the smoothness of the lifting and/or lowering of the evaporator box assembly 100.

Specifically, in one embodiment of the present invention, the guide mechanism 330 may be a bracket fixed to the bottom support plate 200, which has two guide portions 331, each guide portion 331 being a guide groove formed thereon extending in a vertical direction. The peripheral wall of the box body 110 is provided with a slider 113 projecting outward from the outer surface thereof, and the slider 113 is inserted into the above-mentioned guide groove to guide the movement of the evaporator box assembly 100 in the vertical direction along the guide groove. In alternative embodiments of the present invention, the guide 331 may also be a guide rail or other suitable structure for guiding.

Further, the number of guide mechanisms 330 may be two, with two guide mechanisms 330 symmetrically disposed on two opposite sides of the evaporator box assembly 100.

In some embodiments of the present invention, the refrigeration module 10 further includes a compressor 400, a condenser 500 and a throttling element (not shown) disposed on the bottom support plate 200 and outside the box body 110, i.e., the bottom support plate 200 is also used for carrying the compressor 400, the condenser 500 and the throttling element. The cassette 110 of the evaporator cassette assembly 100 may be made of a material having thermal insulating function to prevent unnecessary heat exchange between the evaporator and the compressor 400, between the evaporator and the condenser 500, and between the evaporator and the external ambient space.

Further, a sleeve for thermal insulation is additionally provided around the box body 110 to further insulate the evaporator from heat exchange with the compressor 400, the condenser 500 and the external ambient space. Alternatively, the compressor 400 and the condenser 500 may be located on the same side of the evaporator tank assembly 100. Also provided within the cabinet 110 of the evaporator box assembly 100 is a vacuum insulation panel vertically mounted between the evaporator and the side wall of the cabinet 110 facing the compressor 400 and the condenser 500 to further ensure the insulation effect of the cabinet 110.

In some embodiments of the present invention, rollers 210 may be provided below the bottom support plate 200 to facilitate movement of the refrigeration module 10. In some alternative embodiments of the invention, the refrigeration module 10 further comprises a base, the lower portion of which is provided with rollers, on which the bottom support plate 200 rests, to facilitate the movement of the refrigeration module 10.

The present invention also provides a refrigerating and freezing apparatus, and fig. 5 is a schematic configuration diagram of the refrigerating and freezing apparatus according to an embodiment of the present invention. The refrigerating and freezing device 1 of the present invention comprises at least one storage module 20 and a rack 30. Each storage module 20 defines a storage space therein. The rack 30 is used to support at least one storage module 20. Specifically, in one embodiment of the present invention, the number of the storage modules 20 of the refrigeration and freezing device 1 may be three, and the three storage modules are respectively a top storage module, a middle storage module and a bottom storage module which are sequentially arranged from top to bottom.
