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 further includes a lifting mechanism having at least one lifting unit 310, each lifting unit 310 including a lever 311 rotatably supported on the bottom support plate 200, the resistance-acting end 3111 of the lever 311 extending into the underside of the evaporator box assembly 100 to operatively raise and/or lower the evaporator box assembly 100 using the lever principle and having its supply and return air inlets 111 and 112 in sealed communication with respective air ducts of a storage module disposed adjacently above the refrigeration module 10 when the evaporator box assembly 100 is raised and in spaced relation thereto when the evaporator box assembly 100 is 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 resistance-acting end 3111 of the lever 311 may directly or indirectly abut against the bottom wall of the case 110.

It is particularly emphasized that the lever 311 in the embodiment of the present invention means a mechanical member capable of rotating around a fixed point or a fixed rotation axis according to the principle of a lever. That is, the lever 311 in the embodiment of the present invention may include not only a rod-shaped member that rotates around a fixed point in a narrow sense but also a plate-shaped member, a rod-shaped member, or other suitably shaped member that rotates around a fixed rotation axis in a broad sense as long as the object of the present invention can be achieved. To promote stability during lifting and lowering of the evaporator box assembly 100, in a preferred embodiment of the invention, the lever 311 is a plate-like member that pivots about a fixed pivot axis.

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.

Fig. 3 is a schematic block diagram of a refrigeration module after the evaporator box assembly is concealed in accordance with one embodiment of the present invention, and fig. 4 is a schematic enlarged view of portion a of fig. 3. Referring to fig. 3 and 4, in some embodiments of the invention, each lifting unit 310 further includes a pressing portion 312, the pressing portion 312 being disposed on the bottom support plate 200 and configured to operatively press down on the power-acting end 3112 of the lever 311 to raise the evaporator box assembly 100 through the resistance-acting end 3111 of the lever 311 and/or to operatively release the power-acting end 3112 of the lever 311 to lower the evaporator box assembly 100. Specifically, when the pressure applicator 312 is operable to depress the power-acting end 3112 of the lever 311, the resistance-acting end 3111 thereof is raised upward, thereby directly or indirectly lifting the evaporator box assembly 100, facilitating a secure connection of the evaporator box assembly 100 to the storage module. When it is desired to remove or disassemble the refrigeration module 10 from the entire refrigerated freezer, the user simply operates the pressing portion 312, either directly or indirectly, to release the power-operated end 3112 of the lever 311, causing the power-operated end 3112 to tilt up and the resistance-operated end 3111 to drop down, allowing the evaporator box assembly 100 to drop under its own weight. Therefore, the lifting mechanism is simple in structure, convenient to operate and reliable in adjustment.

It will be appreciated by those skilled in the art that in the embodiment of the present invention, the power-acting end 3112 of the lever 311 means an end portion at or near the power-acting point of the lever 311, and the resistance-acting end 3111 of the lever 311 means an end portion at or near the resistance-acting point of the lever 311.

In some embodiments of the present invention, the pressing portion 312 includes a vertically-placed pressing bar 3121, the pressing bar 3121 is configured to be operable to rotate in a first direction and a second direction opposite to the first direction in a horizontal plane, and to directly or indirectly apply a downward pressure to the power-acting end 3112 of the lever 311 during the rotation in the first direction and gradually release the pressure applied to the power-acting end 3112 of the lever 311 during the rotation in the second direction. Specifically, the first direction may be, for example, a clockwise direction, and the second direction may be a counterclockwise direction; alternatively, the first direction may be counterclockwise and the second direction may be clockwise.

In some embodiments of the present invention, the pressure applying lever 3121 may be a lead screw through which a slider 3122 is penetrated, the slider 3122 being configured to be translated in a vertical direction in accordance with rotation of the pressure applying lever 3121. The bottom of the slider 3122 abuts against the power-application end 3112 of the lever 311 to press and/or release the power-application end 3112 of the lever 311 through the slider 3122. Specifically, the pressing lever 3121 does not generate a displacement in the vertical direction during the rotation. The slider 3122 may be configured to translate vertically downward when the pressure applying lever 3121 rotates in the first direction and to translate vertically upward when the pressure applying lever 3121 rotates in the second direction. That is, the pressing lever 3121 may indirectly apply a downward pressure to the power application end 3112 of the lever 311 through the slider 3122. Since the working principle of the screw 3121 and the sliding block 3122 is known per se and easily obtained by those skilled in the art, they will not be described herein.

Due to the self-locking function of the matching of the screw rod and the sliding block, after the pressure applying rod 3121 stops rotating, the sliding block 3122 and the pressure applying rod 3121 can keep relatively static, namely, no slipping occurs between the pressure applying rod 3121 and the sliding block 3122. That is, after the pressing rod 3121 stops rotating, the sliding block 3122 can be positioned at a certain position, and at this time, the lever 311 can be positioned in a certain state, so that the self-locking of the lifting mechanism is realized, and thus the evaporator box assembly 100 is maintained at a set height, no other positioning operation is required, and the installation and removal processes of the refrigeration module 10 are simplified.

Further, a support base 210 may be provided on the bottom support plate 200, and a limit plate 211 horizontally extending may be provided at an upper end of the support base 210. The limiting plate 211 is provided with a through hole penetrating through the limiting plate 211 up and down, and the pressing rod 3121 penetrates through the through hole of the limiting plate 211 downward and is connected with the bottom plate of the support 210, so that the pressing rod 3121 is vertically supported on the support 210 in a rotatable manner. Alternatively, the pressing lever 3121 may be directly connected to the bottom support plate 200 after passing downward through the through-hole of the limit plate 211, so that the pressing lever 3121 is vertically supported rotatably on the bottom support plate 200. In these embodiments, the through hole of the limit plate 211 may be provided with a thread to be engaged with the screw rod, or the through hole may have a smooth hole wall without a thread. The lever 311 is rotatably supported on the holder 210 with its power application end 3112 extending into the space below the stopper plate 211.

In some alternative embodiments of the present invention, the pressing bar 3121 may also be a bolt vertically penetrating the limiting plate 211 downward and threadedly coupled with the limiting plate 211, and a lower end of the pressing bar 3121 abuts against the power acting end 3112 of the lever 311 to directly press and/or release the power acting end 3112 of the lever 311 through the pressing bar 3121. That is, in an alternative embodiment of the present invention, the through hole of the limit plate 211 is provided with a screw thread to be engaged with the pressure applying lever 3121. When the pressing lever 3121 is rotated in the first direction, the pressing lever 3121 is simultaneously displaced vertically downward, and the lower end of the pressing lever 3121 presses the power-acting end 3112 of the lever 311 downward, tilting the resistance-acting end 3111 of the lever 311 upward, thereby lifting the evaporator box assembly 100. When the pressing lever 3121 is rotated in the second direction, the pressing lever 3121 is simultaneously displaced vertically upward, the lower end of the pressing lever 3121 releases the power-applied end 3112 of the lever 311, and the evaporator box assembly 100 is lowered under its own weight.

It is emphasized that in embodiments of the present invention, the pressure lever 3121 rotates to a different degree and the power-operated end 3112 of the lever 311 is depressed to a different degree, and accordingly, the evaporator box assembly 100 is raised to a different height, i.e., the height of the evaporator box assembly 100 is adjustable depending on the degree to which the pressure lever 3121 is rotated, whereby the refrigeration module 10 of the present invention may be adapted for use with a variety of different types or models of refrigerated freezers.

In some embodiments of the present invention, the upper end of the pressing rod 3121 is further provided with a horizontally extending wrench 3123, so that the wrench 3123 can rotate the pressing rod 3121 to press down and/or release the power-acting end 3112 of the lever 311, thereby lifting and/or lowering the evaporator box assembly 100.

In some embodiments of the present invention, each lifting unit 310 further includes a support 315 for supporting the evaporator box assembly 100. The top of the support 315 abuts the bottom of the evaporator box assembly 100 and the bottom of the support 315 is pivotally connected to the resistive end 3111 of the lever 311 to raise and/or lower the evaporator box assembly 100 through the support 115 during pivoting of the lever 311 about its pivot point. That is, the resistance-acting end 3111 of the lever 311 may indirectly abut the bottom of the evaporator box assembly 100 through the support 315 to indirectly raise and/or lower the evaporator box assembly 100. Specifically, the top of the support 315 may be a horizontally disposed support plate to ensure reliability and stability of its abutment with the evaporator box assembly 100. During the rotation of the lever 311, the support 315 can rotate relative to the resistance-acting end 3111 of the lever 311 to ensure that the top support plate thereof is always kept horizontally disposed, thereby preventing the evaporator box assembly 100 from being tilted and ensuring that a good seal is formed between the air opening of the evaporator box assembly 100 and the storage module.

The inventor of the present invention has recognized that the support portion 315 is displaced not only in the vertical direction but also in the horizontal direction during the rotation of the lever 311. In order to reduce or even eliminate the friction between the support 315 and the evaporator box assembly 100 when it is displaced in the horizontal direction, avoid wear on the evaporator box assembly 100, and avoid displacement of the evaporator box assembly 100 in the horizontal direction, in some embodiments of the invention, the lifting mechanism is specifically designed as follows: each lifting unit 300 of the lifting mechanism further includes two parallel-arranged slide rails 316 secured to the outside of the bottom wall of the evaporator box assembly 100. The support 315 is disposed between the two sliding rails 316 to allow the support 315 to slide along the two sliding rails 316 during the process of being lifted and lowered.

In some embodiments of the present invention, the number of the lifting unit 310 may be one. The pressure applying bar 3121, the sliding block 3122, the wrench 3123, etc. of the lifting unit 310 are located at one side of the evaporator box assembly 100, and the supporting portion 315 of the lifting unit 310 may be located at a central position of the bottom of the evaporator box assembly 100 to prevent the evaporator box assembly 100 from being deflected during the lifting and/or lowering of the evaporator box assembly 100. In some alternative embodiments of the present invention, the number of the lifting units 310 may be two, and the two lifting units 310 are symmetrically disposed to smoothly lift and/or drop the evaporator box assembly 100. In other alternative embodiments of the present invention, the number of the lifting units 310 may also be more than three.

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 220 may be provided beneath 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.
