A plurality of inner chamber-defining members 50 are spaced apart within the inner chamber 20 between the first end wall 24 and the second end wall 25. Specifically, the inner cavity members 50 are sequentially disposed at intervals in the inner cavity 20 along a direction from the first end wall 24 to the second end wall 25, so as to divide the inner storage space of the inner cavity 20 into a plurality of compartments along the direction from the first end wall 24 to the second end wall 25.
The inner cavity members 50 in the inner cavity 20 cooperate with the first sidewall 22 to form a gap for ventilation, and specifically, the inner cavity members 50 and the first sidewall 22 are spaced apart to form the gap.

The circulation direction of the cool air in this embodiment is shown in fig. 2 and 3. The storage area of each inner cavity means 50 is an area where each inner cavity means 50 is used for placing articles, and particularly an area where the inner cavity means 50 faces the top of the inner cavity 20.
Specifically, when the cold air input into the inner cavity 20 by the refrigeration device 40 reaches a certain flow rate, the cold air input into the inner cavity 20 by the refrigeration device 40 flows along the first sidewall surface 22 of the inner cavity 20 based on the principle of the coanda effect, which belongs to the understanding range of those skilled in the art and will not be described herein again.

Moreover, the refrigeration equipment of the embodiment omits the design of the traditional air duct assembly, and is also beneficial to reducing the air resistance in the system, so as to be beneficial to improving the air volume, and the refrigeration device 40 of the embodiment allows the rotating speed of the fan to be reduced under the same air volume requirement, so that the energy consumption can be reduced, and the noise can be reduced. Meanwhile, the design of the traditional air duct assembly is omitted, and the traditional air duct assembly is prevented from occupying the inner space of the refrigeration equipment, so that the refrigeration equipment is allowed to be designed to have larger volume, namely the inner storage space of the inner cavity 20 is designed to be larger volume. In addition, this embodiment refrigeration plant saves the design of traditional wind channel subassembly, has still radically treated the condensation that traditional wind channel subassembly exists, has frosted and the inside freezing scheduling problem that causes the wind channel to block up of wind channel.

That is, on the basis that the cool air flows back through the gaps between the respective inner chamber installation members 50 and the door 30, the flow path of the cool air is increased, thereby being advantageous to increase the diffusion range of the cool air, i.e., making the coverage of the cool air wider, and further being advantageous to improve the cooling efficiency and the cooling effect.
Specifically, a part of the cool air sent into the corresponding storage area of each inner cavity member 50 flows back through the gap between the inner cavity member 50 and the door 30, and a part of the cool air sinks to the storage area of the inner cavity member 50 relatively close to the first end wall surface 24 through the member ventilating structure 60 on the inner cavity member 50, and then flows back to the refrigerating apparatus 40, wherein the circulation direction of the cool air is shown by the dashed arrows in fig. 2.
Alternatively, the storage ventilation structure 60 may be a through hole or a through groove structure, so as to allow the cold air in the storage area corresponding to each internal cavity device 50 to sink to the storage area of the internal cavity device 50 relatively close to the first end wall surface 24 through the storage ventilation structure 60 on the internal cavity device 50, and then flow back to the refrigeration apparatus 40.
It should be noted that the refrigeration device 40 of the present embodiment is configured to deliver the cold air to the second end wall surface 25 as far as possible, that is, to ensure that the cold air is delivered to the second end wall surface 25 along the first side wall surface 22, and after the cold air reaches the second end wall surface 25, the cold air flows back through the gap between the inner cavity placement object 50 and the door 30 and the placement object ventilation structure 60 on the inner cavity placement object 50. Of course, in the process of transporting the cool air along the first side wall surface 22 toward the second end wall surface 25, the cool air inevitably blows toward the storage area of each inner cavity mount 50 when reaching the position of each inner cavity mount 50.
Ventilation structure for placing articles
The placement of the item ventilation structure 60 on the cavity insert 50 is described below.
Please continue to refer to fig. 6. In one embodiment, the plurality of shelf ventilation structures 60 on the inner containment member 50 are disposed on a portion of the inner containment member 50 adjacent to the second sidewall 23 of the inner cavity 20. Specifically, the inner cavity 20 has two opposite second side walls 23, and the inner cavity placing member 50 is provided with a placing member ventilating structure 60 for matching with the cold air backflow, near at least one of the two opposite sides of the two second side walls 23.
Fig. 6 illustrates the inner cavity member 50 having the member ventilating structure 60 disposed near two opposite sides of the two second side walls 23, for example, but not by way of limitation.
Please continue to refer to fig. 7. In an alternative embodiment, the plurality of article-placing ventilation structures 60 on the inner cavity article 50 are disposed at a portion of the inner cavity article 50 close to the first sidewall 22, so that a portion of the cold air sent into the storage region of each inner cavity article 50 flows in a direction away from the first sidewall 22, and a portion of the cold air can flow back through the article-placing ventilation structures 60 on the inner cavity article 50 close to the first sidewall 22, thereby increasing a cold air backflow path close to the first sidewall 22, further facilitating an increase in a diffusion range of the cold air, making a coverage of the cold air wider, and facilitating an improvement in cooling efficiency and a cooling effect.
Please continue to refer to fig. 8. In another alternative embodiment, the plurality of article ventilation structures 60 on the inner cavity member 50 are disposed on the portion of the inner cavity member 50 away from the first sidewall 22, i.e. the article ventilation structures 60 are disposed on the portion of the inner cavity member 50 near the article access opening 21 of the inner cavity 20. In this way, a part of the cold air flowing back in the storage area where each inner cavity object 50 is located may flow back through the gap between the inner cavity object 50 and the door, and a part of the cold air may flow back through the object placing ventilation structure 60 located at the position on the inner cavity object 50 away from the first sidewall 22, so as to increase the cold air flowing back path, thereby being beneficial to increase the diffusion range of the cold air, making the coverage of the cold air wider, being beneficial to improving the refrigeration efficiency and improving the refrigeration effect.
It will be appreciated that in the above embodiments, whether the article venting structure 60 is located in a portion of the inner chamber device 50 adjacent to the second sidewall 23 of the inner chamber 20 (as shown in fig. 6), or the article venting structure 60 is located in a portion of the inner chamber device 50 adjacent to or remote from the first sidewall 22 (as shown in fig. 7 and 8), the article venting structure 60 is located at an edge of the inner chamber device 50 that is generally offset from an area of the inner chamber device 50 that is generally used by a user to place articles, so as to prevent articles stored on the inner chamber device 50 from blocking the cold air return path at the inner chamber device 50 as much as possible.
Please continue to refer to fig. 9. In yet another alternative embodiment, the shelf venting structures 60 are evenly distributed over the inner cavity piece 50, i.e., the portion of the inner cavity piece 50 near the second sidewall surface 23 of the inner cavity 20 and the portions of the inner cavity piece 50 near and away from the first sidewall surface 22, even the areas of the inner cavity piece 50 that are typically used by a user to place items, are provided with the shelf venting structures 60.
Through the manner, the cold air backflow paths on the inner cavity placing object 50 are increased as much as possible, so that even if part of the cold air backflow paths are blocked by the objects stored on the inner cavity placing object 50, the cold air backflow paths provided by the object placing ventilation structures 60 in other areas on the inner cavity placing object 50 can also ensure normal backflow of the cold air, and further ensure that the cold air has a sufficient diffusion range, so as to ensure the refrigeration efficiency and the refrigeration effect.
Referring to fig. 10a-10b, fig. 10a-10b are schematic structural views of a fourth embodiment of a refrigeration apparatus according to the present application.
In one embodiment, in order to ensure that the inner cavity positioning member 50 relatively close to the second end wall 25 can sufficiently flow back to the storage region of the inner cavity positioning member 50 relatively close to the first end wall 24, and further ensure the cooling effect of the storage region of each inner cavity positioning member 50, the total ventilation area of the inner cavity positioning member ventilation structures 60 on each inner cavity positioning member 50 (i.e. the total ventilation area of the inner cavity positioning member ventilation structures 60 on the inner cavity positioning member 50) is gradually increased along the direction from the first end wall 24 to the second end wall 25.
It should be noted that the number of the article ventilation structures 60 included in a unit area of the inner cavity member 50 and the size of the individual article ventilation structures 60 determine the size of the ventilation area of the article ventilation structures 60 on the inner cavity member 50.
The dimensional relationships between the pod venting structures 60 of different internal pod 50 are described below.
Please continue to refer to fig. 10a. In one embodiment, under the condition that the distribution density of the article-holding ventilation structures 60 of each inner cavity apparatus 50 (i.e. the number of the article-holding ventilation structures 60 included in the inner cavity apparatus 50 per unit area) is the same, the ventilation area of the individual article-holding ventilation structures 60 of each inner cavity apparatus 50 is gradually increased along the direction from the first end wall surface 24 to the second end wall surface 25, so that the inner cavity apparatus 50 relatively close to the second end wall surface 25 ensures sufficient cold air to flow back to the storage region of the inner cavity apparatus 50 relatively close to the first end wall surface 24, thereby ensuring the refrigeration effect of the articles stored in the storage region of each inner cavity apparatus 50.
It will be appreciated that the ventilation area of the item ventilation structure 60 may be represented by the cross-sectional area of the item ventilation structure 60. Especially when the cross-sectional shape of the item ventilation structure 60 is circular, i.e., the item ventilation structure 60 is a circular through hole or slot, the ventilation area of the item ventilation structure 60 can be represented by the cross-sectional diameter or radius of the item ventilation structure 60.
The density of distribution of the pod ventilation structures 60 for different internal pod 50 is described below.
Please continue to refer to fig. 10a. In one embodiment, under the condition that the ventilation areas of the individual article-holding ventilation structures 60 of the inner cavity-holding articles 50 are the same, the distribution density of the article-holding ventilation structures 60 of the inner cavity-holding articles 50 is gradually increased along the direction from the first end wall surface 24 to the second end wall surface 25, so that the inner cavity-holding articles 50 relatively close to the second end wall surface 25 ensure sufficient cold air to flow back to the storage areas of the inner cavity-holding articles 50 relatively close to the first end wall surface 24, thereby ensuring the refrigeration effect of the articles stored in the storage areas of the inner cavity-holding articles 50.
Please continue to refer to fig. 10b. In one embodiment, the inner containment article 50 comprises a first sub-article 531 and a second sub-article 532 arranged in a stack. The object placing ventilation structure 60 on the first sub-object placing member 531 comprises a plurality of first sub-ventilation structures 61, the object placing ventilation structure 60 on the second sub-object placing member 532 comprises a plurality of second sub-ventilation structures 62, and the first sub-ventilation structures 61 and the second sub-ventilation structures 62 are arranged correspondingly to each other.
The first sub-object 531 and the second sub-object 532 are disposed to be capable of moving in a mutually staggered manner, so that the correspondingly disposed first sub-ventilation structure 61 and the correspondingly disposed second sub-ventilation structure 62 can move in a mutually staggered manner, so as to adjust the overlapping area of the orthographic projections of the correspondingly disposed first sub-ventilation structure 61 and the correspondingly disposed second sub-ventilation structure 62 on the reference plane (as shown by the plane α in fig. 10 b), and further adjust the total ventilation area of the internal cavity object 50 overhead object ventilation structure 60 formed by the first sub-object 531 and the second sub-object 532.
It should be noted that the reference plane is perpendicular to the stacking direction of the first sub-placement 531 and the second sub-placement 532, and the central axes of the first sub-ventilation structure 61 and the second sub-ventilation structure 62 are perpendicular to the reference plane, i.e. the first sub-ventilation structure 61 and the second sub-ventilation structure 62 are straight holes.
It will be appreciated that there is an overlap of the orthographic projections of the first sub-ventilation structure 61 and the second sub-ventilation structure 62 on the reference plane for ventilation. Therefore, when the first sub-ventilation structure 61 and the second sub-ventilation structure 62 are relatively moved to the extent that the orthographic projections of the first sub-ventilation structure and the second sub-ventilation structure are overlapped on the reference plane, the ventilation area of the internal cavity device 50 on the device ventilation structure 60 is maximized; when the first sub-ventilation structure 61 and the second sub-ventilation structure 62 are displaced from each other such that there is no overlap in the orthographic projections of the two on the reference plane, the inner cavity member 50 has no ventilation function.
Of course, in other embodiments of the present application, the inner cavity member 50 may include a larger number of sub-members, and is not limited to the first sub-member 531 and the second sub-member 532, which is not limited herein.
Form of ventilating structure for article holding member
In one embodiment, the shelf ventilation structure 60 is disposed through the inner chamber containment article 50. Specifically, the placement element ventilation structure 60 may be a hole structure formed in the inner cavity placement element 50, as shown in fig. 6 to 10a and 10 b; or the edge of the inner cavity member 50 is recessed toward the interior of the inner cavity member 50 to form a recess-type article ventilation structure 60, as shown in fig. 18, which can be applied to the above-mentioned embodiment in which the article ventilation structure 60 is disposed at the edge of the inner cavity member 50.
Referring to fig. 11, fig. 11 is a schematic structural diagram of a first embodiment of a cavity placement object in the present application.
In an alternative embodiment, the inner cavity member 50 comprises a plurality of support bars 52 arranged in a cross manner, the plurality of support bars 52 are crossed with each other to form a net-shaped inner cavity member 50, wherein the net holes on the net-shaped inner cavity member 50 are the member ventilating structure 60.
Referring to fig. 12, fig. 12 is a schematic structural diagram of a second embodiment of a cavity placement object in the present application.
In another alternative embodiment, the inner cavity member 50 includes a first sub-member 531 and a second sub-member 532 disposed in a stacked manner, the first sub-member 531 includes a plurality of first supporting bars 521 extending along a same direction, the second sub-member 532 includes a plurality of second supporting bars 522 extending along a same direction, and the first supporting bars 521 and the second supporting bars 522 extend in different directions, such that the first supporting bars 521 and the second supporting bars 522 are disposed in a crossed manner in the stacked direction of the first sub-member 531 and the second sub-member 532, thereby forming the mesh-shaped inner cavity member 50, wherein the mesh openings on the mesh-shaped inner cavity member 50 are the member ventilation structure 60.
Of course, in other embodiments of the present application, the form of the shelf ventilation structure 60 is not limited to that described above and is not limited thereto.
Ventilation groove
Referring to fig. 13, fig. 13 is a schematic view of a fifth embodiment of a B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1.
In one embodiment, the first end edge 503 of the first inner chamber member 511 is provided with a plurality of wind shielding projections 55, and a ventilation groove 54 is formed between adjacent wind shielding projections 55.
Specifically, the edge of the first inner cavity member 511 close to the first side wall 22 is recessed in the direction away from the first side wall 22, and a plurality of ventilation grooves 54 are formed along the edge, and the ventilation grooves 54 perform a ventilation function, thereby facilitating to adjust the amount of cold air passing through the gap between the first inner cavity member 511 and the first side wall 22 in a unit time. Also, due to the presence of the wind shielding protrusion 55, the risk that the articles placed on the first inner cavity member 511 fall from the gap between the first inner cavity member 511 and the first side wall surface 22 can be reduced.
Between the adjacent ventilation grooves 54 is a wind shielding protrusion 55 protruding toward the first sidewall 22 relative to the ventilation grooves 54, and the wind shielding protrusion 55 cooperates with the ventilation grooves 54 to adjust the amount of cold air passing through the gap between the first inner cavity member 511 and the first sidewall 22 per unit time. Also, the ventilation grooves 54 and the wind shielding projections 55 are alternately arranged one by one in the opposing direction of the two second side wall surfaces 23 of the inner cavity 20.
Of course, it can also be understood that the edge of the first inner cavity member 511 close to the first side wall 22 is provided with a plurality of wind shielding protrusions 55 protruding toward the first side wall 22, and a ventilation groove 54 is formed between adjacent wind shielding protrusions 55, which is not limited herein.
Further, the width of the slot of the ventilation groove 54 is preferably larger than the width of the slot bottom thereof, so as to facilitate the injection molding of the ventilation groove 54, i.e., the process of preparing the ventilation groove 54 on the first inner chamber device 511. The width of the slot and the slot bottom of the ventilation groove 54 is understood to mean the length of the two in the opposing direction of the two second side walls 23 of the inner cavity 20.
Please continue to refer to fig. 13. In one embodiment, the wind shielding protrusion 55 of the first inner cavity member 511 near the edge of the first sidewall 22 abuts against the first sidewall 22, and the ventilation groove 54 and the first sidewall 22 cooperate to surround the gap formed for the cold air flowing along the first sidewall 22 to pass through, and then to be conveyed to the second end wall 25. In this way, the ventilation groove 54 plays a ventilation role, so that the cooling air circulation is ensured, and meanwhile, the clearance formed by the ventilation groove 54 and the first side wall surface 22 in a matched and surrounded manner is small, so that the articles stored on the first inner cavity placing object 511 can be prevented from falling from the clearance between the first inner cavity placing object 511 and the first side wall surface 22.
Of course, in other embodiments of the present application, the ventilation groove 54 and the wind shielding protrusion 55 of the first inner cavity member 511 near the edge of the first sidewall 22 may be spaced apart from the first sidewall 22 to form a gap for the cool air to pass through.
The side wall of the inner cavity body is matched with cold air backflow
Referring to fig. 14, fig. 14 isbase:Sub>A schematic view ofbase:Sub>A second embodiment ofbase:Sub>A cross-sectional structure alongbase:Sub>A directionbase:Sub>A-base:Sub>A of the refrigeration apparatus shown in fig. 1.
In one embodiment, the connection between the second sidewall 23 of the inner cavity 20 and the inner cavity member 50 is provided with a plurality of sidewall ventilation structures 70, and the cool air can flow back through the sidewall ventilation structures 70. That is to say, on the basis that cold air put the clearance backward flow between thing and the door body through each interior cavity in above-mentioned embodiment, increased cold air's backward flow route to be favorable to increasing cold air's diffusion range, even make cold air's coverage wider, and then be favorable to improving refrigeration efficiency and improve refrigeration effect.
Specifically, a portion of the cool air delivered to the corresponding storage area of each inner cavity member 50 flows back through the gap between the inner cavity member 50 and the door 30, and a portion of the cool air sinks through the sidewall ventilation structure 70 to the storage area of the inner cavity member 50 relatively close to the first end wall 24, and then flows back to the refrigeration device 40. Wherein the flow of cool air at the sidewall vent structure 70 is shown by the dashed arrows in fig. 14.
It should be noted that the cooling device 40 of the present embodiment is configured to deliver the cool air to the second end wall surface 25 as far as possible, that is, to ensure that the cool air is delivered to the second end wall surface 25 along the first side wall surface 22, and after the cool air reaches the second end wall surface 25, the cool air flows back through the gap between the inner cavity placing object 50 and the door 30 and the side wall ventilation structure 70. Of course, in the process of transporting the cool air along the first side wall surface 22 toward the second end wall surface 25, the cool air inevitably blows toward the storage area of each inner cavity mount 50 when reaching the position of each inner cavity mount 50.
Side wall ventilation structure
Please continue to refer to fig. 14. In one embodiment, the side wall ventilation structure 70 includes a channel structure, i.e., a return channel 71, extending in the direction opposite the first and second end walls 24 and 25. The cool air can be returned in the direction from the second end wall surface 25 to the first end wall surface 24 through the return air guide grooves 71.
Specifically, the second side wall surface 23 of the inner cavity 20 may be recessed in a direction away from the inner cavity-mounted object 50 to form a return air guide groove 71; or ribs (namely, a return air diversion protrusion 72) are arranged on the second side wall surface 23 of the inner cavity 20, the ribs protrude towards the direction close to the inner cavity object 50, and a return air diversion groove 71 is formed between adjacent ribs.
The number of the return air guide grooves 71 is preferably plural, the plural return air guide grooves 71 are sequentially arranged at intervals along the opposite direction (as shown by the arrow Y in fig. 2, the same below) of the access opening 21 of the inner cavity 20 and the first side wall surface 22, and the relatively convex return air guide protrusions 72 are formed between the adjacent return air guide grooves 71. The return air guide grooves 71 and the return air guide protrusions 72 are alternately arranged one by one in the opposite direction of the storage opening 21 and the first side wall surface 22.
It should be noted that, in the present embodiment, the return air guide protrusions 72 protruding toward the inside of the inner cavity 20 relative to the second side wall surface 23 are preferably disposed on the second side wall surface 23 of the inner cavity 20, and the return air guide grooves 71 are further formed between adjacent return air guide protrusions 72. Therefore, the cold air flowing back to the second side wall surface 23 still depends on the second side wall surface 23 to flow based on the coanda effect, and flows along the return air guide groove 71 at the same time, so that the problem that the return air guide groove 71 formed in the manner that the second side wall surface 23 is sunken into the return air guide groove 71 to be guided by the return air guide groove 71 is solved, and the realization of the flow guide function of the return air guide groove 71 is facilitated, and the cold air guide effect is improved.
Referring to fig. 15, fig. 15 is a schematic structural view of a return air duct according to a first embodiment of the present application.
In one embodiment, the cross-sectional area of the return air guide groove 71 decreases gradually from the second end wall surface 25 to the first end wall surface 24, which means that the cross-sectional area of the portion of the return air guide groove 71 relatively close to the second end wall surface 25 is larger, so that as much cold air as possible enters the return air guide groove 71 and flows back through the return air guide groove 71, and the return air guide groove 71 has a good return effect and high return efficiency.
Please continue to refer to fig. 15. In an embodiment, the plurality of return air guiding grooves 71 on the second side wall surface 23 are radially disposed toward the second end wall surface 25, so that the cold air to be returned near the second end wall surface 25 enters the return air guiding grooves 71 as much as possible and returns through the return air guiding grooves 71, and the return air guiding grooves 71 have a good return effect and a high return efficiency.
Referring to fig. 16, fig. 16 is a schematic structural view of a second embodiment of the return air guide duct of the present application.
In one embodiment, the distance between the end of each return air guide protrusion 72 on the second side wall 23 near the second end wall 25 and the second end wall 25 gradually decreases from the middle toward the access opening 21 of the inner cavity 20 and the first side wall 22. This means that the distance between the end of the return air guide projection 72 closer to the storage opening 21 and the first side wall surface 22 and the second end wall surface 25 is smaller, and the distance between the end of the return air guide projection 72 closer to the second end wall surface 25 and the second end wall surface 25 is larger, the distance being further away from the storage opening 21 and the first side wall surface 22.
Through the above manner, the return air diversion protrusion 72 relatively close to the storage opening 21 and the first side wall surface 22 can guide the cold air to enter the return air diversion groove 71, so that as much cold air as possible enters the return air diversion groove 71 and flows back through the return air diversion groove 71, and further the return air diversion groove 71 has a good return effect and high return efficiency.
Of course, in other embodiments of the present application, the side wall ventilation structure 70 is not limited to the form of the return air guide groove 71 in the above embodiments, and is not limited thereto.
Side wall ventilation structure and connecting piece
Referring to fig. 17, fig. 17 is a schematic diagram of a second embodiment of a front view structure of the refrigeration apparatus shown in fig. 1.
In one embodiment, the inner cavity member 50 is fixed to the second sidewall 23 by mounting, so as to fix the relative position of the inner cavity member 50 in the inner cavity 20, thereby achieving the function of storing articles. Correspondingly, the second sidewall surface 23 is provided with a connecting member 231 for connecting the inner cavity placing object 50, so as to mount and fix the inner cavity placing object 50 on the second sidewall surface 23.
Specifically, the two opposite sides of the inner cavity object 50 are respectively close to the two opposite second side wall surfaces 23 of the inner cavity 20, and after the two ends of the inner cavity object 50 close to the second side wall surfaces 23 are respectively installed on the corresponding second side wall surfaces 23 through the connecting pieces 231, the inner cavity object 50 can be installed and fixed on the second side wall surfaces 23, so as to fix the opposite positions of the inner cavity object 50 in the inner cavity 20.
In one embodiment, the connector 231 includes two connecting tabs 2311 spaced apart from each other, as shown in fig. 17. The spacing direction of the two connecting protrusions 2311 is the opposite direction of the first end wall surface 24 and the second end wall surface 25 of the inner cavity 20. The two connecting protruding strips 2311 are used for clamping the end portion of the inner cavity device 50 close to the second sidewall surface 23, so as to mount and fix the inner cavity device 50 on the second sidewall surface 23.
Further, referring to fig. 18 and fig. 19, two connecting protruding strips 2311 extend along the opposite direction of the article access opening 21 of the inner cavity 20 and the first side wall surface 22, and two second side wall surfaces 23 opposite to the inner cavity 20 are respectively provided with two corresponding sets of connecting pieces 231 for installing and fixing the same inner cavity placing article 50. After the user aligns the two ends of the inner cavity placement object 50 with the gaps between the two connecting protruding strips 2311 of the corresponding connecting piece 231, the user can push the inner cavity placement object 50 along the extending direction of the connecting protruding strips 2311, so that the two opposite ends of the inner cavity placement object 50 are respectively clamped between the two corresponding connecting protruding strips 2311, and the fixing of the relative positions of the inner cavity placement object 50 in the inner cavity 20 is completed.
Of course, since the number of the inner cavity placing members 50 in the inner cavity 20 is plural, a plurality of sets of connecting members 231 are sequentially arranged on the second side wall surface 23 of the inner cavity 20 at intervals along the opposite direction of the first end wall surface 24 and the second end wall surface 25, and are respectively used for connecting and fixing different inner cavity placing members 50, as shown in fig. 17.
In other embodiments of the present application, the connection element 231 may also include only one connection protrusion 2311, and the inner cavity member 50 may also be mounted and fixed on the second sidewall 23 by placing the end of the inner cavity member 50 close to the second sidewall 23 above the connection protrusion 2311 and supporting the inner cavity member 50 by the connection protrusion 2311, which is not limited herein.
Please continue to refer to fig. 17-19. In one embodiment, in order to achieve the effect of the backflow of the cold air at the side of the second sidewall surface 23 of the inner cavity 20, a sidewall ventilation structure 70 is required at the joint of the second sidewall surface 23 and the inner cavity member 50, so as to achieve the ventilation effect at the joint of the second sidewall surface 23 and the inner cavity member 50.
Considering that the sidewall ventilation structure 70 and the connection member 231 are required to be disposed at the connection position of the second sidewall 23 and the inner cavity placing member 50, the design of the sidewall ventilation structure 70 and the connection member 231 is considered at the connection position of the second sidewall 23 and the inner cavity placing member 50 in the embodiment of the present application.
Please continue to refer to fig. 17 and 18. In one embodiment, the second side wall 23 has return air guiding grooves 71 and return air guiding protrusions 72 alternately arranged one by one along the opposite direction of the storage opening 21 and the first side wall 22. The return air guide groove 71 is used for realizing the ventilation effect of the joint of the second side wall surface 23 and the inner cavity object 50, and the connecting piece 231 is required to be arranged on the return air guide protrusion 72, so that the design of the side wall ventilation structure 70 and the connecting piece 231 is considered at the joint of the second side wall surface 23 and the inner cavity object 50.
Furthermore, the surfaces of the return air guide protrusions 72 facing the inner cavity member 50 are respectively provided with a connecting member 231 to ensure that the inner cavity member 50 is reliably fixed on the second sidewall 23, which is beneficial to improving the overall reliability of the refrigeration apparatus.
Object placing ventilation structure and side wall ventilation structure are matched to realize multi-path cold air backflow
Referring to fig. 17 to 20, fig. 20 is a partial schematic view of a C-C direction cross-sectional structure of the refrigeration equipment shown in fig. 19.
In one embodiment, the inner chamber element 50 (including the first inner chamber element and the second inner chamber element as described in the above embodiments) has a plurality of element ventilation structures 60, and the junction between the second sidewall 23 of the inner chamber 20 and the inner chamber element 50 has a plurality of sidewall ventilation structures 70. The cool air may flow back through the storage ventilation structure 60 and the sidewall ventilation structure 70. That is to say, on the basis that the cold air flows back through the gap between each inner cavity device 50 and the door 30, the backflow path of the cold air is further increased, the circulating refrigeration of the multipath backflow of the cold air is realized, the diffusion range of the cold air is further increased, the coverage range of the cold air is wider, and the improvement of the refrigeration effect is further facilitated.
In one embodiment, based on the sidewall ventilation structures 70 in the form of the return air guiding grooves 71 and the return air guiding protrusions 72 alternately arranged one by one in the opposite direction of the access opening 21 and the first sidewall surface 22, the article placement ventilation structures 60 are formed in the first side edge 501 and/or the second side edge 502 of the inner cavity device 50, that is, the article placement ventilation structures 60 are groove structures, as shown in fig. 18. Also, FIG. 18 illustrates the case where both the first side edge 501 and the second side edge 502 are provided with recessed item ventilation structures 60.
Specifically, the inner cavity component 50 is recessed to form a concave-shaped component ventilating structure 60 corresponding to the air return guiding groove 71 on the second side wall 23. Further, the article ventilation structure 60 may be abutted with the return air guiding groove 71 to form a channel for returning the cool air, which is beneficial to increase the maximum amount of the cool air returning at the position of the second side wall surface 23 of the inner cavity 20, as shown in fig. 18.
Please continue to refer to fig. 19 and 20. In an alternative embodiment, the connector 231 is in the form of two connecting tabs 2311 spaced from each other in the above-described embodiment. The side wall ventilation structure 70 includes a first ventilation hole 73 and a second ventilation hole 74. The first vent 73 is provided in the inner chamber-setting member 50. Specifically, the first vent hole 73 is provided in a portion where the inner cavity member 50 is sandwiched between the two connecting ribs 2311. The second ventilation holes 74 are provided in the connection protrusions 2311. Specifically, the two connecting protruding strips 2311 of the connecting piece 231 are respectively provided with the second vent holes 74, and the second vent holes 74 on the two connecting protruding strips 2311 are correspondingly arranged, so that after the internal cavity containing object 50 is mounted and fixed on the connecting piece 231, the second vent holes 74 on the two connecting protruding strips 2311 are communicated with the first vent holes 73 on the internal cavity containing object 50, and the first vent holes 73 and the second vent holes 74 form a cold air backflow channel at the position where the internal cavity containing object 50 is connected with the second side wall surface 23, so that the mounting and fixing of the internal cavity containing object 50 on the second side wall surface 23 are also realized while the position of the second side wall surface 23 of the internal cavity 20 is matched with the cold air backflow.
In addition, for the case that the connection piece 231 only includes one connection protrusion 2311 in the above embodiment, the connection protrusion 2311 included in the connection piece 231 may be provided with the second vent hole 74 communicated with the first vent hole 73, so that the first vent hole 73 and the second vent hole 74 can also cooperate to achieve the cold air backflow at the position of the second side wall surface 23 of the inner cavity 20, which is not limited herein.
Further, the inner chamber placing member 50 is further provided with a third vent hole 63, the third vent hole 63 is provided in other regions of the inner chamber placing member 50 except for the region clamped between the two connecting protruding strips 2311, and the third vent hole 63 is provided close to the first vent hole 73. That is, the third ventilation hole 63 is provided on the side of the first ventilation hole 73 that faces away from the second side-wall surface 23, as shown in fig. 19 and 20. Therefore, the maximum cold air backflow amount of the side of the second side wall surface 23 of the inner cavity 20 can be increased, which is beneficial to improving the cold air backflow efficiency, and is further beneficial to improving the refrigeration efficiency and improving the refrigeration effect.
Air supply diversion trench
Referring to fig. 21, fig. 21 is a schematic diagram of a third embodiment of a front view structure of the refrigeration equipment shown in fig. 1.
In one embodiment, the cool air output from the cooling device 40 is blown along the first sidewall 22 of the inner cavity 20. For the first side wall surface 22 to have a good airflow guiding effect, the first side wall surface 22 of the present embodiment is provided with a guiding groove structure extending along the opposite direction of the first end wall surface 24 and the second end wall surface 25, i.e. an air supply guiding groove 81, the air supply guiding groove 81 is communicated to the refrigerating device 40, and cold air can flow to the second end wall surface 25 along the air supply guiding groove 81, thereby being beneficial to improving the airflow guiding effect of the first side wall surface 22.
Specifically, the first side wall surface 22 of the inner cavity 20 may be recessed in a direction away from the inner cavity for placing the object 50, so as to form an air supply guiding groove 81; or ribs (i.e., air supply guide protrusions 82) are disposed on the first side wall 22 of the inner cavity 20, the ribs protrude toward the inside of the inner cavity 20, and air supply guide grooves 81 are formed between adjacent ribs.
The number of the air supply guide grooves 81 is preferably plural, the plural air supply guide grooves 81 are sequentially arranged at intervals along the opposite direction of the two second side wall surfaces 23 of the inner cavity 20, and the air supply guide protrusion 82 which is relatively protruded is formed between the adjacent air supply guide grooves 81. The air supply guide grooves 81 and the air supply guide protrusions 82 are alternately arranged one by one in the opposite direction of the two second side wall surfaces 23 of the inner chamber 20.
It should be noted that, in the present embodiment, it is preferable that the air supply guide protrusions 82 protruding toward the inside of the inner cavity 20 relative to the first side wall surface 22 are provided on the first side wall surface 22 of the inner cavity 20, and the air supply guide grooves 81 are further formed between the adjacent air supply guide protrusions 82. In this way, the cold air output by the refrigeration device 40 to the first sidewall surface 22 still depends on the first sidewall surface 22 to flow based on the coanda effect, and flows along the air supply guiding groove 81 at the same time, so that the problem that the air supply guiding groove 81 formed in the manner that the first sidewall surface 22 is recessed requires the cold air to sink into the air supply guiding groove 81 to be guided by the air supply guiding groove 81 is avoided, which is beneficial to ensuring the realization of the air guide function of the air supply guiding groove 81 and improving the guiding effect of the cold air.
The air supply guiding groove 81 and the air supply guiding protrusion 82 on the first side wall surface 22 may abut against the edge of the first inner cavity object 511 close to the first side wall surface 22, so as to form a gap between the first inner cavity object 511 and the first side wall surface 22 for the cold air to pass through. Of course, the air supply guiding groove 81 and the air supply guiding protrusion 82 on the first side wall surface 22 may also be separately disposed at an interval from the edge of the first inner cavity object 511 close to the first side wall surface 22, so as to form a gap between the first inner cavity object 511 and the first side wall surface 22 for the cold air to pass through.
Referring to fig. 22, fig. 22 is a schematic structural diagram of an air supply guiding gutter according to a first embodiment of the present application.
In one embodiment, the cross-sectional area of the air supply guide groove 81 gradually decreases in the direction from the first end-wall surface 24 to the second end-wall surface 25. This means that the cross-sectional area of the portion of the supply guide groove 81 relatively close to the first end wall surface 24 is large, which is advantageous in ensuring that as much cool air as possible enters the supply guide groove 81 and flows along the supply guide groove 81, i.e., ensuring sufficient amount of cool air input.
Referring to fig. 23, fig. 23 is a schematic structural view of a second embodiment of an air supply guiding gutter according to the present application.
In one embodiment, the cross-sectional area of the air supply guide groove 81 gradually increases in the direction from the first end-wall surface 24 to the second end-wall surface 25. This means that the cross-sectional area of the portion of the air supply guide groove 81 relatively close to the first end wall surface 24 is small. When the input amount of the cool air amount is constant, the flow guide groove 81 has a relatively high cool air flow rate in a portion close to the first end wall surface 24. Based on the coanda effect principle, the cold air in the portion of the air supply guiding groove 81 relatively close to the first end wall surface 24 adheres to the first side wall surface 22 with a relatively high ability, so that the cold air can be ensured to adhere to the first side wall surface 22 and flow under the guidance of the air supply guiding groove 81, which is further beneficial to improving the air flow guiding effect of the air supply guiding groove 81.
Please continue to refer to fig. 21. In one embodiment, the distance between the end of each blower flow guide projection 82 on the first side wall 22 near the first end wall 24 and the first end wall 24 gradually decreases from the middle toward the second side wall 23. This means that the distance between the end of the blower flow guide projection 82 closer to the second side wall surface 23 and the first end wall surface 24 is smaller, and the distance between the end of the blower flow guide projection 82 farther from the second side wall surface 23 and the first end wall surface 24 is larger.
In this way, the air supply guide protrusions 82 relatively close to the second side wall surface 23 guide the cold air to enter the air supply guide grooves 81, so that as much cold air as possible enters the air supply guide grooves 81 and is supplied through the air supply guide grooves 81, and then is conveyed to the storage areas of the inner cavity containing objects 50 to refrigerate the stored objects, i.e., the air supply guide grooves 81 have a good air flow guide effect.
Referring to fig. 21 and 24, fig. 24 is a schematic view illustrating a cross-sectional structure in a direction D-D of the refrigerating apparatus shown in fig. 21.
In an embodiment, in the case that the cooling device 40 is disposed outside the inner cavity 20 (which will be described in detail below), the inner cavity 20 has an air inlet 28 and an air return 29, and the cooling device 40 inputs cold air into the inner cavity 20 through the air inlet 28 and then returns to the cooling device 40 through the air return 29, so as to realize cold air circulation.
Since the size of the outlet of the cooling device 40 for outputting the cool air is limited, there is a problem that the amount of the cool air introduced into the air guide groove 81 relatively far from the air inlet 28 is insufficient. In view of this, in this embodiment, the number of the air inlets 28 on the inner cavity 20 is preferably multiple, the air inlets 28 are sequentially arranged at intervals along the opposite direction of the two second side wall surfaces 23 of the inner cavity 20, the air inlets 28 are communicated with the air supply guiding grooves 81 on the first side wall surface 22, and each air inlet 28 is communicated with the refrigerating device 40 through a corresponding air duct, so as to convey the cold air output by the refrigerating device 40 to each air inlet 28, and then convey the cold air to the air supply guiding grooves 81 on the first side wall surface 22 through each air inlet 28.
In this way, since the plurality of air inlets 28 of the inner cavity 20 are sequentially arranged at intervals along the opposite direction of the two second side wall surfaces 23 of the inner cavity 20, and then the air inlets 28 respectively convey the cool air to the plurality of air supply guiding grooves 81 on the first side wall surface 22, the amount of the cool air input by the air supply guiding grooves 81 can be kept relatively consistent.
Air supply diversion groove, air supply diversion protrusion, ventilation groove and wind shielding protrusion
Referring to fig. 25 to 27, fig. 25 is a schematic view of an eighth embodiment of a B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, fig. 26 is a schematic view of a ninth embodiment of the B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, and fig. 27 is a schematic view of a tenth embodiment of the B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1.
In an embodiment, the edge of the first inner cavity member 511 close to the first side wall 22 is provided with ventilation grooves 54 and wind shielding protrusions 55 alternately arranged one by one in the opposite direction of the two second side walls 23 of the inner cavity 20. The first side wall 22 is provided with air supply guiding grooves 81 and air supply guiding protrusions 82 which are alternately arranged one by one along the opposite direction of the two second side walls 23 of the inner cavity 20. The ventilation groove 54 and the wind shielding protrusion 55 of the first inner cavity member 511 are disposed opposite to the air supply guiding groove 81 and the air supply guiding protrusion 82 of the first side wall surface 22, so as to form a passage for the cool air to pass through between the first inner cavity member 511 and the first side wall surface 22.
Please continue to refer to fig. 25. In one embodiment, the ventilation groove 54 of the first inner chamber component 511 is disposed opposite to the blowing guide groove 81 of the first sidewall 22.
Through the above manner, the design of the ventilation groove 54 and the wind shielding protrusion 55 on the first inner cavity placement object 511 reduces the risk that articles fall from the gap between the first inner cavity placement object 511 and the first side wall surface 22 while achieving the ventilation effect, and the ventilation groove 54 is arranged opposite to the air supply diversion trench 81, so that the area of the ventilation region where the air supply diversion trench 81 is located is increased, which is beneficial to ensuring that sufficient amount of cold air passes between the first inner cavity placement object 511 and the first side wall surface 22, and further beneficial to ensuring the refrigeration effect of the articles stored in each inner cavity placement object 50.
In the present embodiment, the wind shielding protrusion 55 is disposed opposite to the air flow guide protrusion 82. Further, the ventilation groove 54 may be abutted to the air supply guiding groove 81, and the air blocking protrusion 55 abuts to the air supply guiding protrusion 82 to prevent the air blocking protrusion 55 from being embedded in the air supply guiding groove 81 and the air supply guiding protrusion 82 from being embedded in the ventilation groove 54, so as to ensure that a ventilation area between the first inner cavity placement object 511 and the first side wall surface 22 has a sufficient area, ensure that sufficient amount of cold air passes between the first inner cavity placement object 511 and the first side wall surface 22, and be beneficial to ensuring a refrigeration effect of the articles stored in each inner cavity placement object 50.
Of course, in other embodiments of the present application, the wind shielding protrusion 55 on the first inner cavity member 511 may also be disposed at a distance from the air guiding groove 81 and the air guiding protrusion 82, i.e. the first inner cavity member 511 is disposed at a distance from the first side wall 22, which is not limited herein.
Please continue to refer to fig. 26. In an alternative embodiment, the ventilation groove 54 of the first inner chamber component 511 is disposed opposite to the air guide protrusion 82 of the first sidewall 22. Further, the ventilation groove 54 is butted against the air supply guide protrusion 82. In other embodiments of the present application, the ventilation groove 54 may be spaced apart from the air guide protrusion 82.
Through the manner, the design of the ventilation groove 54 and the wind shielding protrusion 55 on the first inner cavity placement object 511 reduces the risk that articles fall from the gap between the first inner cavity placement object 511 and the first side wall surface 22 while achieving the ventilation effect, and the design of the ventilation groove 54 abutting against the air supply flow guide protrusion 82 realizes the ventilation function of the position of the air supply flow guide protrusion 82, that is, on the basis of the design of the air supply flow guide groove 81 and the air supply flow guide protrusion 82 on the first side wall surface 22, the ventilation position between the first inner cavity placement object 511 and the first side wall surface 22 is increased, so that the sufficient amount of cold air can be ensured to pass between the first inner cavity placement object 511 and the first side wall surface 22, and the refrigeration effect of the articles stored in each inner cavity placement object can be ensured.
Please continue to refer to fig. 27. In one embodiment, the ventilation groove 54 and the wind shielding protrusion 55 of the first inner cavity member 511 are disposed to be engaged with the air guiding groove 81 and the air guiding protrusion 82 of the first sidewall 22. Specifically, the wind shielding protrusion 55 of the first inner cavity member 511 is inserted into the wind guide groove 81 of the first side wall 22, and the wind guide protrusion 82 of the first side wall 22 is inserted into the ventilation groove 54 of the first inner cavity member 511.
In this way, the present embodiment allows the area of the ventilation area between the first inner chamber component 511 and the first side wall 22 to be adjusted by the concave-convex engagement of the ventilation groove 54 and the wind shielding protrusion 55 on the first inner chamber component 511 with the wind guiding groove 81 and the wind guiding protrusion 82 on the first side wall 22, thereby facilitating the adjustment of the amount of cold air to be fed into the storage area of each first inner chamber component 511.
Air volume regulation of articles placed in different inner cavities
Please continue to refer to fig. 2 and 3. In one embodiment, a plurality of first inner cavity members 511 are disposed in the region between the refrigeration device 40 and the second end wall 25, and the plurality of first inner cavity members 511 are sequentially disposed at intervals along the direction from the first end wall 24 to the second end wall 25 to divide the inner storage space of the inner cavity 20 into a plurality of compartments along the direction from the first end wall 24 to the second end wall 25. The cooling air input into the inner cavity 20 by the cooling device 40 is blown through the gap (i.e., the ventilation area) between the first inner cavity placement piece 511 and the first side wall surface 22, and is further respectively sent into the storage area of each first inner cavity placement piece 511, so as to cool the stored articles. Wherein the amount of cold air fed into the storage area of each first inner cavity member 511 is adjusted by setting the difference in the area of the ventilation area between the different first inner cavity members 511 and the first side wall surface 22.
Specifically, the area of the ventilation area between each first inner cavity member 511 and the first side wall surface 22 is gradually reduced in the direction from the first end wall surface 24 to the second end wall surface 25. In this way, the area of the ventilation area between the first inner cavity member 511 and the first side wall 22 relatively close to the first end wall 24 is larger than the area of the ventilation area between the first inner cavity member 511 and the first side wall 22 relatively close to the second end wall 25, so that when the cold air passing through the ventilation area between the first inner cavity member 511 and the first side wall 22 relatively close to the first end wall 24 reaches the first inner cavity member 511 relatively close to the second end wall 25, part of the cold air is blocked by the first inner cavity member 511 relatively close to the second end wall 25 and flows to the storage area of the first inner cavity member 511 relatively close to the first end wall 24, thereby realizing that the cold air conveyed between each first inner cavity member 511 and the first side wall 22 is respectively conveyed to the storage area of each first inner cavity member 511.
It will be appreciated that a ventilation zone between the first inner cavity member 511 and the first side wall 22 may be formed by the first inner cavity member 511 and the first side wall 22 being spaced from each other; or the ventilation groove 54 and the wind shielding protrusion 55 on the first inner cavity placing object 511 are arranged opposite to the first side wall surface 22 to form a ventilation area; or the first inner cavity placing member 511 is arranged opposite to the air supply guiding groove 81 and the air supply guiding protrusion 82 on the first side wall surface 22 to form a ventilation area; or the ventilation groove 54 and the wind shielding protrusion 55 of the first inner cavity member 511 are disposed opposite to the air flow guiding groove 81 and the air flow guiding protrusion 82 of the first sidewall 22 to form a ventilation area, as shown in fig. 25 to 27, which is not limited herein.
In one embodiment, the volume of the storage region of each first inner cavity means 511 is generally relatively uniform, and the amount of cold air required for the storage region of each corresponding first inner cavity means 511 is generally designed to be equal, so that the refrigeration effect of the items stored in each first inner cavity means 511 is relatively uniform, meaning that the same refrigeration effect can be achieved by a user storing the items in any first inner cavity means 511.
Based on the above design concept that the air volume required for the storage region of each first inner cavity member 511 is relatively uniform, if it is considered that the cool air supplied to the storage region of each first inner cavity member 511 is only from the cool air conveyed between the first inner cavity member 511 and the first side wall 22, the area of the ventilation region between each first inner cavity member 511 and the first side wall 22 decreases in an equal difference manner along the direction from the first end wall 24 to the second end wall 25, and the area of the ventilation region between the first inner cavity member 511 closest to the second end wall 25 and the first side wall 22 is taken as a tolerance, so that the amount of the cool air supplied to the storage region of each first inner cavity member 511 is kept relatively uniform.
For example, as shown in fig. 2, first inner cavity placing objects G1, G2, G3 are sequentially disposed in the inner cavity 20 along a direction from the first end wall surface 24 to the second end wall surface 25, areas of ventilation areas between the first inner cavity placing objects G1, G2, G3 and the first side wall surface 22 are S1, S2, S3, respectively, where the equal difference of S1, S2, S3 decreases progressively, and S3 is a tolerance, for example, S1: S2: S3 is 3.
However, based on the design concept that the air volume required for the storage area of each first inner cavity member 511 is relatively consistent, considering that the storage ventilation structure on the inner cavity member 50 (including the first inner cavity member 511) and the sidewall ventilation structure on the second sidewall 23 cooperate with the cold air backflow in the above-described embodiment of the present application, the cold air supplied to the storage area of each first inner cavity member 511 not only comes from the cold air conveyed between the first inner cavity member 511 and the first sidewall 22, but also includes the cold air backflow. Also, the amount of the returned cool air at the position of the first inner cavity member 511 closer to the second end wall 25 is larger, and the demand for the cool air transferred between the first inner cavity member 511 and the first side wall 22 is smaller.
In view of this, in the present embodiment, in the direction from the first end wall surface 24 to the second end wall surface 25, the area of the ventilation area between each first inner cavity member 511 and the first side wall surface 22 gradually decreases, and the difference in the area of the ventilation area between adjacent first inner cavity members 511 and the first side wall surface 22 gradually decreases.
Similarly, the description is given by taking the example of the inner cavity 20 shown in fig. 2, in which first inner cavity-placing objects G1, G2, G3 are sequentially arranged along the direction from the first end-wall surface 24 to the second end-wall surface 25, where S1 > S2 > S3, and S1-S2 > S2-S3, for example, S1: S2: S3 is 6.
It should be noted that, since the size of the ventilation area between each first inner cavity member 511 and the first side wall 22 in the opposite direction of the two second side walls 23 of the inner cavity 20 is relatively consistent, the size (area) of the ventilation area between the first inner cavity member 511 and the first side wall 22 can be characterized by using the distance between the first inner cavity member 511 and the first side wall 22.
Of course, in other embodiments of the present application, the storage areas of different first inner cavity placement objects 511 may also be designed with different air volumes as needed, and only the size (area) of the ventilation area between the first inner cavity placement object 511 and the first side wall 22 needs to be adjusted, which is not described herein again.
The refrigerating plant is externally arranged
Please continue to refer to fig. 21 and 24. In one embodiment, the refrigeration device 40 may be disposed outside of the inner cavity 20. For the case where the refrigeration unit 40 is disposed outside the inner cavity 20, the inner cavity 20 also has an air inlet 28 and an air return 29. The refrigerating device 40 delivers cold air to the inside of the inner cavity 20 through the air inlet 28, and the cold air circulates in the inner cavity 20 and then flows back to the refrigerating device 40 through the air return opening 29.
It should be noted that, because the temperature of the refrigeration device 40 is low, especially when the inner cavity 20 is used as a refrigerating chamber of a refrigeration apparatus, the refrigeration device 40 is usually disposed outside the inner cavity 20 to avoid the temperature inside the inner cavity 20 from being too low due to the low temperature of the refrigeration device 40.
Of course, in other embodiments of the present application, even if the inner cavity 20 is used as a refrigerating chamber of a refrigeration device, the refrigeration device 40 can be disposed inside the inner cavity 20, and only the temperature of the refrigeration device 40 needs to be properly adjusted to avoid the temperature inside the inner cavity 20 from being too low. In addition, in the case where the refrigeration device 40 is disposed inside the inner cavity 20, the inner cavity 20 may be designed without the air inlet 28 and the air return 29.
For example, in the case that the refrigeration device 40 is disposed outside the inner cavity 20, since the refrigeration device 40 in the embodiment of the present invention delivers the cold air to the inside of the inner cavity 20 along the direction from the first end wall surface 24 to the second end wall surface 25, it is preferable that the first end wall surface 24 is a bottom inner wall of the inner cavity 20 and the second end wall surface 25 is a top inner wall of the inner cavity 20, that is, the refrigeration device 40 delivers the cold air to the inside of the inner cavity 20 along the direction from the bottom inner wall of the inner cavity 20 to the top inner wall of the inner cavity 20.
Built-in refrigerating device
Please continue to refer to fig. 24. The refrigeration equipment shown in fig. 24 can also be understood as that the refrigeration device 40 is disposed inside the inner cavity 20, but the refrigeration equipment is additionally provided with a fan cover disposed on the refrigeration device 40, the fan cover is provided with an air inlet 28 and an air return opening 29, the refrigeration device 40 outputs cold air through the air inlet 28, and the cold air flows back to the refrigeration device 40 through the air return opening 29. It can be seen that the provision of the hood ensures the formation of a cool air circulation circuit.
In addition, in the present application, unless otherwise expressly specified or limited, the terms "connected," "stacked," and the like are to be construed broadly, e.g., as meaning permanently attached, removably attached, or integral to one another; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
