Detailed Description
For a clearer understanding of technical features, objects, and effects of the present invention, a specific embodiment of the present invention will be described with reference to the accompanying drawings.
One embodiment of the present invention provides a refrigeration apparatus having a separate refrigeration unit, the structure of which is shown in fig. 1 to 3. The refrigeration apparatus 1 includes:
a housing 11 defining at least one refrigeration chamber 19, the refrigeration chamber 19 for providing a cryogenic environment to items contained within the refrigeration chamber 19;
a refrigerating unit chamber 12 located in the housing 11 and defined by the housing 11 at an upper portion of the refrigerating chamber 19;
a refrigerating unit 20 is accommodated in the refrigerating unit chamber 12, the refrigerating unit 20 having a refrigerating assembly 21 and a supporting member 22 for supporting the refrigerating assembly. The refrigeration assembly is used to cool the refrigeration chamber 19. The support member is removably mounted in the refrigeration unit cavity 12. The refrigeration unit 20 itself is a self-contained module that is separable from the housing 11 and removably mounted within the refrigeration unit cavity 12.
The refrigeration unit cavity 12 has first and second bosses 122 and 122 'on opposite sidewalls thereof, respectively, and first and second rails are mounted on top surfaces of the first and second bosses 122 and 122', respectively. The dashed circle a in fig. 1 and the dashed circle B in fig. 2 show one of the guide rails 3, and fig. 4 and 5 are enlarged schematic views of portions of the dashed circle a and the dashed circle B in fig. 1 and 2, respectively. Specific details of the first and second guide rails will be described in further detail below. As shown in fig. 4 and 5, the guide rail 3 has a first state and a second state, wherein fig. 4 shows the case when the guide rail 3 is in the first state and fig. 5 shows the case when the guide rail 3 is in the second state.
When the guide rail 3 is in the first state, as shown in fig. 4, the guide rail member 33 of the guide rail 3 is in the "flat" position (first position) without supporting the refrigeration unit 20, the refrigeration unit 20 being supported by its bottom 23 on the bottom wall 121 of the refrigeration unit cavity 12, as shown in fig. 1.
When the rail 3 is in the second state, as shown in fig. 5, the rail member 33 of the rail 3 is in the "raised" position (second position), at which time the overall height of the rail 3 increases due to the lifting of the rail member 33, such that the rail member 33 provides an upward force to the flange 24 of the support part 22 of the refrigeration unit 20 (which flange extends laterally from the support part 22 to the outside of the refrigeration unit 20 to above the rail member 33, as shown in fig. 4 and 5), thereby lifting the refrigeration unit 20 from the bottom wall 121 of the refrigeration unit cavity 12, separating the bottom 23 of the refrigeration unit 20 from the bottom wall 121, as shown in fig. 2. That is, the refrigerating unit 20 is suspended from the bottom wall 121 and supported only by the guide rail 3.
When the guide rail 3 is in the second state as shown in fig. 5, the refrigerating unit 20 is supported by the corresponding guide rail 3 through the flanges 24 at both sides thereof, and the bottom 23 of the refrigerating unit 20 is in a separated state from the bottom wall 121 of the refrigerating unit chamber 12, so that there is no friction therebetween. And the sealing connection between the refrigerating unit 20 and the refrigerating chamber 19 for communication of the cooled gas is broken due to the separation between the bottom 23 of the refrigerating unit 20 and the bottom wall 121 of the refrigerating unit chamber 12. At this time, the refrigerating unit 20 may be slid on the guide rail 3 by the flanges 24 at both sides of the supporting member 22 thereof, thereby achieving a movement in which the refrigerating unit 20 slides into the refrigerating unit chamber 12 and a movement in which the refrigerating unit 20 slides out of the refrigerating unit chamber 12, as shown in fig. 3.
Thus, as shown in fig. 3, after opening the door panels of the refrigeration unit cavity 12 (not shown for clarity of illustration of the internal refrigeration unit 20) and ensuring that the refrigeration unit is unobstructed in the extraction direction, the refrigeration unit 20 may be extracted horizontally from the refrigeration unit cavity 12 by pulling the refrigeration unit 20 (e.g., via the handles 25 on the support members 22) with the guide rail 3 in the second state.
Similarly, the refrigeration unit 20 can also be pushed horizontally into the refrigeration unit cavity 12 by the guide rail 3 in the second state. Then, the guide rail 3 is changed from the second state to the first state, so that the height of the refrigerating unit 20 in the refrigerating unit chamber 12 is lowered until the bottom 23 of the refrigerating unit 20 contacts the bottom wall 121 of the refrigerating unit chamber 12, so that the refrigerating unit 20 is fixed in the refrigerating unit chamber 12. Furthermore, the refrigerating unit 20 is pressed down on the bottom wall 121 of the refrigerating unit chamber 12 due to its large weight, and thus a sealed connection for the cooled gas communication between the refrigerating unit 20 and the refrigerating chamber 19 is achieved.
The refrigeration unit 20 may be pulled out of the refrigeration unit cavity 12 or pushed into the refrigeration unit cavity 12 like a drawer so that the refrigeration unit 20 may be conveniently, quickly, and labor-effectively removed from or placed into the refrigeration unit cavity 12.
The refrigerating device with the structure can separate the refrigerating unit from the refrigerating device in a drawing way, thereby having the following beneficial effects:
1. when in daily maintenance, the whole refrigeration unit can be easily separated from the refrigeration equipment, so that the internal condition of the refrigeration unit can be conveniently and accurately judged;
2. when the refrigerating unit fails, only one new refrigerating unit needs to be replaced, so that the intelligent refrigerating container can be restored to the normal running state in a short time, and meanwhile, the labor cost is saved.
In addition, according to the guide rail provided by the embodiment of the application, the refrigeration unit can be positioned at the top of the refrigeration chamber, so that a lower space convenient to take and place is reserved as the space of the refrigeration chamber. Thus, the convenience of the user can be greatly improved, and the use experience of the user is improved.
As described above, by providing the guide rail as described above in the refrigerating unit chamber 12 of the refrigerating apparatus, the refrigerating unit 20 can be detached or installed in a sliding manner, thereby facilitating maintenance and renewal of the refrigerating unit 20. The guide rail employed in the present application has two states. When the refrigeration unit 20 is not required to slide, the rail is in the first state, and the rail does not support the refrigeration unit. When the refrigeration unit 20 is required to slide, the guide rail is in the second state, and the guide rail supports the refrigeration unit so that the refrigeration unit can slide on the guide rail. That is, the guide rail supports and receives the force of the refrigerating unit only when the refrigerating unit 20 is required to slide. Since the weight of the refrigerating unit is generally large, the guide rail having two states can prevent the guide rail from being subjected to the pressure of the refrigerating unit for a long time, thereby preventing the guide rail from being damaged and further improving the service life of the guide rail. Hereinafter, technical details of the guide rail employed in the present application will be further described.
Fig. 6 shows a perspective view of one rail for a refrigeration unit according to one embodiment of the present application. As shown in fig. 6, one guide rail 3 for a refrigerating unit according to one embodiment of the present application includes: support member, pivot 32, guide rail member 33.
The support member includes a first support body 31 and a second support body 31'. The first and second supporting bodies 31 and 31 'have first and second through holes 311 and 311', respectively, therein. The support member is used to secure the guide rail 3 to other devices when the guide rail 3 is mounted to the devices (e.g. to the refrigeration unit cavity 12 defined by the housing of the refrigeration apparatus, particularly to the bottom wall or side wall of the refrigeration unit cavity 12, more particularly to the boss on the side wall of the refrigeration unit cavity 12, as shown in fig. 1 to 5);
the shaft 32 has an axis C-C' extending in the longitudinal direction. The rotation shaft 32 passes through the first through hole 311 and the second through hole 311' in the first support body 31 and the second support body 31', so as to be supported on the support member and rotatable about the axis C-C '.
The rail member 33 extends along the axis C-C 'and is fixedly connected to the shaft 32 such that the rail member 33 is rotatable about the axis C-C' from a first position to a second position as the shaft 32 rotates.
In order to more clearly show the structure and relative positional relationship of the rotating shaft 32 and the rail member 33, fig. 7 and 8 show the rotating shaft 32 and the rail member 33 after the support member is removed. Wherein the track member 33 is in the first position in fig. 6 and the track member 33 is in the second position in fig. 7.
Fig. 8 shows a schematic view of the structure of the guide rail 3 (with the support member removed) as seen from the bottom of the guide rail 3 shown in fig. 6. As shown in fig. 8, the rail member 33 has a strip-shaped body 331 extending along an axis C-C ', the strip-shaped body 331 being L-shaped in cross section in a plane perpendicular to the axis C-C'. The strip-shaped body 331 has a first end piece 332 and a second end piece 332' at both ends, wherein the first end piece 332 has a shape of a rectangle with chamfers as shown in fig. 9. Fig. 9 is a side view of the combination of the rotating shaft 32 and the rail member 33 shown in fig. 7. Returning to fig. 8, the first and second end pieces 332 and 332 'have first and second through holes 333 and 333', respectively. The rotation shaft 32 passes through the first through hole 333 and the second through hole 333 'and is fixed to the first end piece 332 and the second end piece 332', thereby achieving a fixed connection between the rail member 33 and the rotation shaft 32.
When the rail member 33 is located at the first position (the flat position shown in fig. 4 and 6), a point of the rail member 33 farthest from the bottom of the rail 3 in the vertical direction has a height H1 with respect to the bottom of the rail 3, that is, the rail 3 has the first height H1 as a whole (shown in fig. 4); when the rail member 33 is located at the second position (the raised position shown in fig. 5 and 7), a point of the rail member 33 farthest from the bottom of the rail 3 in the vertical direction has a height H2 with respect to the bottom of the rail 3, that is, the rail 3 as a whole has the second height H2 (shown in fig. 5). The second height H2 is greater than the first height H1.
As the rail member 33 rotates from the first position to the second position, the overall height of the rail 3 increases from H1 to H2, such that the rail member 33 provides an upward force to the flange 24 of the support component 22 of the refrigeration unit 20 (which flange extends laterally outward of the refrigeration unit 20 from the support component 22 to above the rail member 33 as shown in fig. 4 and 5), such that the refrigeration unit 20 is raised from the bottom wall 121 of the refrigeration unit cavity 12 to separate the bottom 23 of the refrigeration unit 20 from the bottom wall 121. That is, the refrigerating unit 20 is suspended from the bottom wall 121 and supported only by the guide rail 3. At this time, the refrigerating unit 20 may slide along the axis C-C' on the rail member 33. The height of the support member is equal to or less than the second height H2 to avoid blocking of the sliding movement of the refrigeration unit 20.
In the above-described embodiment, the guide rail 3 according to one embodiment of the present application is described taking the "hollow" guide rail member 33 having an L-shaped cross section as an example. However, the configuration of the rail member 33 is not limited to the structure described in the above embodiment. For example, the rail members may not be "hollow" structures as shown in fig. 6-8, but rather "solid" structures. For example, the rail member may be rectangular, circular, oval, etc. in cross-section. As long as the cross-sectional shape of the rail member is configured to satisfy the following conditions: when the rail member 33 is located at the first position, the rail 3 has a first height H1 as a whole; when the rail member 33 is located at the second position, the rail 3 has a second height H2 as a whole; the second height H2 is greater than the first height H1.
In a preferred embodiment, as shown in fig. 7 and 9, one of the ribs 339 of the rail member 33 extending along the axis C-C' has a chamfer that abuts the guided object during rotation of the rail member 33 from the first position to the second position. Because the rib 339 is chamfered, rotation of the rail member 33 from the first position to the second position may be smoother and less labor intensive. Correspondingly, the first end piece 332 of the rail member 33 has a rectangular shape having a chamfer D as shown in fig. 9, which corresponds to the chamfered rib 339 shown in fig. 7. Also in correspondence with this, the cross section of the strip-shaped main body 331 of the rail member 33 is L-shaped with a chamfer (corresponding to the rib 339).
In another preferred embodiment, the rail member is polygonal in cross-section, one of the rail members extending along axis C-C' and having a chamfer against a rib 339 of the guided object during rotation of the rail member from the first position to the second position, the corners of the polygonal cross-section of the rail member corresponding to the rib 339 being chamfered. The polygon may be, for example, a rectangle.
In accordance with one embodiment of the present application, the shaft 32 may be formed of a rod-shaped object, although this is not limiting. In other embodiments, the shaft may be formed of two rod-like objects located at both ends of the rail member, respectively. In other embodiments, the shaft 32 may be formed of other forms of components as long as it is capable of rotating the rail member fixed thereto about the axis.
According to one embodiment of the present application, at least one end of the spindle 32 has a snap mechanism for engaging the rotary tool and being transferred to the spindle by a force applied by the rotary tool to rotate the spindle, thereby rotating the rail member. As shown in fig. 6 to 9, the engagement mechanism 35 may be, for example, an end portion of the rotation shaft 32 having a quadrangular cross section. The rotary tool may be, for example, a wrench or the like. When the rotation rail member is required to rotate from the first position to the second position, a rotation tool such as a wrench may be used to apply a force to the engagement mechanism 35 to rotate the shaft, thereby rotating the rail member. The engagement means 35 may also be, for example, an end of a shaft having a triangular or hexagonal cross section.
According to one embodiment of the present application, wherein the rail member is made of a rigid metallic material, such as stainless steel, to reduce friction between the rail member and the guided object.
According to one embodiment of the present application, the above-described guide rail may be fixed into the refrigeration unit cavity 12, in particular to a bottom wall or a side wall of the refrigeration unit cavity 12, to mate with a support member of the refrigeration unit 20, in particular a flange 24 of a support member 22 of the refrigeration unit 20, to effect a sliding movement of the refrigeration unit 20 into the refrigeration unit cavity 12 or a sliding movement out of the refrigeration unit cavity 12.
It should be understood that although the present disclosure has been described in terms of various embodiments, not every embodiment is provided with a separate technical solution, and this description is for clarity only, and those skilled in the art should consider the disclosure as a whole, and the technical solutions in the various embodiments may be combined appropriately to form other embodiments that will be understood by those skilled in the art.
The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention. Any equivalent alterations, modifications and combinations thereof will be effected by those skilled in the art without departing from the spirit and principles of this invention, and it is intended to be within the scope of the invention.
