The cold air input into the inner cavity 20 by the refrigerating device 40 flows along the first side wall surface 22 of the inner cavity 20 by utilizing Coanda Effect (Coanda Effect), and is further blown through the gap between the inner cavity 50 and the first side wall surface 22, so that the cold air reaches the storage area of each inner cavity 50 to refrigerate the articles stored in the storage area of each inner cavity 50, and then flows back to the refrigerating device 40 at least through the gap between each inner cavity 50 and the door 30, and thus, the cold air circulation is realized. Further, in other embodiments of the present application, the ventilation structure at the position of the second side wall surface 23 of the inner cavity 20 and the ventilation structure on the inner cavity device 50 may be utilized to cooperate with the cold air backflow, so as to increase the backflow path of the cold air, which is beneficial to increase the diffusion range of the cold air, and further improve the cooling efficiency and the cooling effect, which will be described in detail below. 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.

Further, after the door 30 is closed, the door object 31 on the door 30 and the inner cavity object 50 in the inner cavity 20 are disposed at an interval, and the cold air flows back to the refrigerating apparatus 40 at least through a gap between the inner cavity object 50 and the door object 31, as shown in fig. 2.

That is to say, the refrigeration device 40 of the present embodiment provides cold air circulation to the inner storage space of the inner cavity 20 to perform circulation refrigeration on the articles stored in the inner storage space of the inner cavity 20, which is beneficial to improving the refrigeration effect and increasing the refrigeration efficiency.

It should be noted that the cooling device 40 of the present embodiment outputs the cool air directly to the inside of the inner cavity 20, and blows the cool air flowing along the first side wall surface 22 of the inner cavity 20 to the storage area of each inner cavity placement object 50. This is different from the refrigerating plant among the prior art through locating the inside storing space input cold air of the outside wind channel subassembly of interior cavity to traditional wind channel subassembly needs to set up ventilation structure respectively corresponding each interior cavity storage region of putting the article, in order to transmit cold air to the storage region that corresponds interior cavity and put the article.

Therefore, the refrigeration equipment of the embodiment omits a traditional air duct assembly, and is beneficial to reducing the production cost of the refrigeration equipment. 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 49 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 cured condensation, frosting and the inside freezing problem that causes the wind channel to block up that causes of wind channel that traditional wind channel subassembly exists.

In one embodiment, the inner lumen element 50 comprises a first inner lumen element 511 and a second inner lumen element 512, as shown in FIG. 3. The cooling device 40 is disposed adjacent to the first end wall surface 24, and the first inner chamber-defining member 511 is disposed in the region between the cooling device 40 and the second end wall surface 25. Specifically, the first inner cavity member 511 is disposed at an interval from the first sidewall 22, and the cold air input into the inner cavity 20 by the cooling device 40 is blown through a gap between the first inner cavity member 511 and the first sidewall 22. The second inner chamber element 512 is disposed corresponding to the refrigeration device 40 and correspondingly disposed in the region between the first inner chamber element 511 and the first end wall surface 24, and the returned cool air passes through the storage region of the second inner chamber element 512 to refrigerate the articles stored in the storage region of the second inner chamber element 512, and then returns to the refrigeration device 40. The number of the first inner cavity member 511 and the second inner cavity member 512 may be plural.

The inner cavity body is provided with an object matched with the backflow of cold air

Referring to fig. 2, 6 to 9, fig. 6 is a schematic diagram of a first embodiment of a B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, fig. 7 is a schematic diagram of a second embodiment of the B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, fig. 8 is a schematic diagram of a third embodiment of the B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, and fig. 9 is a schematic diagram of a fourth embodiment of the B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1.

In one embodiment, the inner chamber means 50 (including the first inner chamber means 511 and the second inner chamber means 512 as described in the above embodiments, as shown in fig. 3) is provided with a plurality of means ventilation structures 60, and the cool air can flow back through the means ventilation structures 60 on the inner chamber means 50. 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 slot structure, so as to allow the cool air of the storage area corresponding to each inner cavity-placing member 50 to sink to the storage area of the inner cavity-placing member 50 relatively close to the first end wall surface 24 through the storage ventilation structure 60 on the inner cavity-placing member 50, and then flow back to the refrigeration device 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 chamber component 50 having the component ventilation structure 60 disposed adjacent to two opposite sides of the two second sidewalls 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 of each inner cavity placement object 50 can flow back through the gap between the inner cavity placement object 50 and the door, and a part of the cold air can flow back through the object placement ventilation structure 60 on the inner cavity placement object 50 away from the first side wall surface 22, so that the cold air backflow path is increased, the cold air diffusion range is enlarged, the cold air coverage is wider, the refrigeration efficiency is improved, and the refrigeration effect is improved.

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. 10 a. In one embodiment, under the condition that the distribution density of the article-placing ventilation structures 60 of each inner cavity-placing member 50 (i.e. the number of the article-placing ventilation structures 60 included in the inner cavity-placing members 50 per unit area) is the same, the ventilation area of the individual article-placing ventilation structures 60 of each inner cavity-placing member 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-placing member 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-placing member 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-placing member 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. 10 a. 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. 10 b. 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 so that the orthographic projections of the two on the reference plane do not overlap, 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 article venting structure 60 is disposed through the inner chamber 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. 27, 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. And, the ventilation grooves 54 and the wind shielding protrusions 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 thereof in the opposite 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.

Flow guiding structure

Referring to fig. 14, fig. 14 is a schematic view of a second embodiment of a cross-sectional structure along a direction a-a of the refrigeration apparatus shown in fig. 1.

In one embodiment, the first surface 505 of the first inner chamber element 511 is provided with a flow directing structure 56, the flow directing structure 56 being arranged adjacent to the first end edge 503, the flow directing structure 56 having a flow directing surface 561, the flow directing surface 561 being directed towards the second end edge 504 and away from the first inner chamber element 511 for directing the flow of the cooling air along the first surface 505.

Specifically, the end of the first inner cavity member 511 close to the first sidewall 22 is provided with a flow guiding structure 56. The diversion structure 56 has a diversion surface 561 facing the first end wall surface 24 and the storage opening 21 for guiding the cool air delivered from the gap between the first inner cavity component 511 and the first side wall surface 22 to enter the storage area corresponding to the first inner cavity component 511 for refrigerating and preserving the stored items. The flow direction of the cool air at the diversion surface 561 is shown by the dotted arrow in fig. 14.

Specifically, the flow guiding structure 56 is located on the surface of the first inner cavity member 511 facing the first end wall surface 24, and the flow guiding structure 56 is used for guiding the cold air to flow along the surface of the first inner cavity member 511 facing the first end wall surface 24 where the flow guiding structure 56 is located.

For example, in the case that the second end wall surface 25 is the top inner wall of the inner cavity 20 and the first end wall surface 24 is the bottom inner wall of the inner cavity 20 as shown in fig. 14, and when the refrigeration device is correctly placed, the relative direction of the first end wall surface 24 and the second end wall surface 25 is the up-down direction. Specifically, the flow guide structure 56 is disposed on the surface of the first inner cavity member 511 facing the lower first inner cavity member 511, and is used for guiding the cool air to the storage region of the lower first inner cavity member 511 adjacent to the first inner cavity member 511 where the flow guide structure 56 is disposed.

Further, the diversion surface 561 is preferably an arc surface extending in an arc transition manner, as shown in fig. 14, so that the diversion surface 561 has a good capability of guiding the airflow, and thus the airflow can be smoothly guided, which is beneficial to improving the airflow guiding effect of the diversion structure 56.

Further, in an exemplary embodiment, the flow guiding surface 561 may be a cambered surface with a fixed curvature, that is, the flow guiding surface 561 is a circular arc surface, as shown in fig. 15. Since the curvatures of the positions on the flow guide surface 561 are the same, the preparation process of the flow guide structure 56 is simplified, the process difficulty is reduced, and the process yield is improved. For example, the flow guiding surface 561 shown in fig. 15 is a quarter of a circular arc surface, which is only necessary for discussion and is not limiting.

In an alternative embodiment, please refer to fig. 16, the flow guiding surface 561 may also be a curved surface with gradually changing curvature. The curvature of a certain position of the cambered surface describes the bending degree of the position, and the larger the curvature means the larger the bending degree of the position, and vice versa, the same is used below. Specifically, the curvature of each position on the flow guide surface 561 is gradually decreased in a direction away from the first side wall surface 22, that is, the position of the flow guide surface 561 farther from the first side wall surface 22 is closer to a plane.

Therefore, the part of the flow guiding surface 561 with the larger curvature contacts the cold air flow first, so as to guide the cold air to flow along the flow guiding surface 561, and have a good fluency, and then along with the gradual reduction of the curvature, the cold air flowing along the flow guiding surface 561 is gradually guided to flow along the surface of the first inner cavity device 511 where the flow guiding surface 561 is located, so as to further guide the cold air to enter the storage area of the first inner cavity device 511. It can be seen that the flow guiding surface 561 of the present embodiment can smoothly guide the cool air delivered from the gap between the first inner cavity member 511 and the first sidewall 22 to the storage area of the first inner cavity member 511, and has a good guiding effect.

Flow guiding structure and wind shielding protrusion

Referring to fig. 14 and 17, fig. 17 is a schematic structural view of a first embodiment of a first internal cavity positioning member according to the present application.

In one embodiment, the end of the first inner chamber component 511 near the first sidewall 22 is provided with ventilation grooves 54 and wind shielding protrusions 55 arranged alternately. Since the wind-shielding protrusion 55 is relatively close to the first sidewall 22, the diversion structure 56 of the present embodiment is disposed on the wind-shielding protrusion 55, specifically, on the surface of the wind-shielding protrusion 55 close to the first end wall 24, so as to guide the cold air blocked by the wind-shielding protrusion 55 to the storage area of the first inner cavity object 511 through the diversion structure 56.

Drainage structure

Referring to fig. 18, fig. 18 is a schematic view of a third embodiment of a sectional structure along a direction a-a of the refrigeration apparatus shown in fig. 1.

In one embodiment, to ensure that the cool air output by the cooling device 40 of this embodiment is transmitted to the second end wall 25 along the first side wall 22 as far as possible, the first inner cavity member 511 is provided with a flow guiding structure 57, the flow guiding structure 57 has a flow guiding surface 571, and the flow guiding surface 571 faces a direction away from the second end edge 504 of the first inner cavity member 511 and a direction from the second surface 506 to the first surface 505 of the first inner cavity member 511.

Specifically, the end of the first inner cavity member 511 near the first sidewall 22 is provided with a drainage structure 57. The flow guide structure 57 has a flow guide surface 571, and the flow guide surface 571 faces the first end wall surface 24 and also faces the first side wall surface 22, so as to guide the cold air to be conveyed along the first side wall surface 22 to the second end wall surface 25 as far as possible. The flow of the cool air at the diversion surface 571 is shown by the dotted arrow in fig. 18.

Further, the drainage structure 57 may be disposed on the first surface 505, that is, the drainage structure 57 may be disposed on a side of the first inner cavity means 511 close to the first end wall surface 24, as shown in fig. 18; alternatively, the drainage structure 57 may be disposed on the second surface 506, i.e. the drainage structure 57 may be disposed on a side of the first inner chamber component 511 away from the first end wall surface, as shown in fig. 22; alternatively, the drainage structure 57 is directly disposed on the side of the first inner chamber component 511 close to the first sidewall 22.

Further, the flow guiding surface 571 is preferably an arc surface extending in an arc transition manner, as shown in fig. 18, so that the flow guiding surface 571 has a good capability of guiding the air flow, and thus the air flow can be smoothly guided, which is beneficial to improving the air flow guiding effect of the flow guiding structure 57.

Further, in an exemplary embodiment, the drainage surface 571 may be a cambered surface with a fixed curvature, i.e., the drainage surface 571 is a circular arc surface, as shown in fig. 19. Since the curvatures of the positions on the drainage surface 571 are the same, the preparation process of the drainage structure 57 can be simplified, the process difficulty can be reduced, and the process yield can be improved. For example, the flow-directing surface 571 shown in fig. 19 is a quarter of a circular arc surface, which is only needed for discussion purposes and is not limiting.

In an alternative embodiment, referring to fig. 18 and 20, the drainage surface 571 may also be a curved surface with gradually changing curvature. Specifically, the curvature of each position on the drainage surface 571 gradually increases in a direction approaching the second end wall surface 25, that is, the position of the drainage surface 571 farther from the second end wall surface 25 approaches a plane.

In this way, the portion of the flow guiding surface 571 with the smaller curvature contacts the cold air flow first, so that the cold air can be guided to flow along the flow guiding surface 571 with good fluency, and then the cold air flowing along the flow guiding surface 571 is gradually guided to flow towards the first sidewall 22 along the gradually increasing curvature, so that the cold air is conveyed to the second end wall 25 along the first sidewall 22 as far as possible.

Drainage structure and ventilation groove

Referring to fig. 21, fig. 21 is a schematic structural view of a second embodiment of the first internal cavity positioning member according to the present application.

In an embodiment, the end of the first inner cavity member 511 close to the first sidewall 22 is provided with a ventilation groove 54 and a wind shielding protrusion 55, which are alternately arranged one by one, especially in a case where the wind shielding protrusion 55 abuts against the first sidewall 22, in order to guide the cold air to be delivered to the second sidewall 25 along the first sidewall 22 as far as possible, the flow guiding structure 57 is preferably provided at a region of the first inner cavity member 511 close to the bottom of the ventilation groove 54, and the cold air passing through the ventilation groove 54 is guided by the flow guiding structure 57 to flow along the first sidewall 22, so that the cold air output from the refrigerating apparatus 40 is delivered to the second sidewall 25 along the first sidewall 22 as far as possible.

Further, the drainage structure 57 may be disposed on the surface of the first inner cavity member 511 close to the first end wall surface 24, or the drainage structure 57 may be disposed on the surface of the first inner cavity member 511 far from the first end wall surface 24. In both of the above manners, the flow of the cool air passing through the ventilation groove 54 toward the first side wall surface 22 can be guided.

Barrier piece

Please continue to refer to fig. 18. In an embodiment, a protruding stopper 58 is disposed at an end of the first inner cavity placement object 511 close to the first side wall 22, so that after the article placed on the first inner cavity placement object 511 abuts against the stopper 58, the stopper 58 limits the article from further approaching the first side wall 22, and further prevents the article placed on the first inner cavity placement object 511 from blocking a gap between the first inner cavity placement object 511 and the first side wall 22, that is, a blowing duct of cold air from being blocked, and also prevents the article placed on the first inner cavity placement object 511 from falling from the gap between the first inner cavity placement object 511 and the first side wall 22.

Specifically, the dam 58 is provided on the side of the surface of the first inner cavity member 511 on which the article is placed, for stopping the article placed on the first inner cavity member 511 where the dam 58 is located.

Barrier and ventilation groove

Please continue to refer to fig. 18 and 21. In one embodiment, the end of the first inner chamber component 511 near the first sidewall 22 is provided with ventilation grooves 54 and wind shielding protrusions 55 arranged alternately. In order to prevent the objects placed on the first inner cavity member 511 from blocking the gap between the first inner cavity member 511 and the first side wall 22 and from falling out of the gap between the first inner cavity member 511 and the first side wall 22, the dam 58 is provided at least in the region of the first inner cavity member 511 near the bottom of the ventilation groove 54. That is, at least the region of the first inner chamber element 511 near the bottom of the ventilation groove 54 is provided with the dam 58, and the dam 58 may extend to both sides to the region near the wind-shielding protrusion 55.

It should be noted that the dam 58 is disposed on the first inner cavity member 511 in the area close to the bottom of the ventilation groove 54, which does not mean that the dam 58 must directly contact the area of the first inner cavity member 511 close to the bottom of the ventilation groove 54, or the dam 58 may be elevated above the area of the first inner cavity member 511 close to the bottom of the ventilation groove 54, which is not limited herein.

Further, the plurality of ventilation grooves 54 of the end portion of the first inner chamber component 511 close to the first side wall surface 22 include a first ventilation groove 541 and a second ventilation groove 542, as shown in a and b of fig. 21. The width of the first ventilating groove 541 is larger than that of the second ventilating groove 542, and the blocking member 58 is disposed at least in an area of the first inner cavity placement object 511 close to the bottom of the first ventilating groove 541 (the same applies to the above) to ensure that the blocking member 58 has a sufficient size (i.e., the length of the blocking member 58 in the opposite direction of the two second side walls of the inner cavity, wherein the opposite direction of the two second side walls 23 of the inner cavity 20 is shown by the arrow X in fig. 3, the same applies below) for blocking the object from further approaching the first side wall 22, so as to ensure the blocking effect.

Further, on the end portion of the first inner chamber component 511 close to the first side wall surface 22, the dam 58 and the opposite sides of the first ventilating groove 541 are provided with second ventilating grooves 542, respectively, as shown in a and b of fig. 21. Due to the existence of the blocking member 58, the articles placed on the first inner cavity placing object 511 are difficult to enter the positions of the second ventilating grooves 542 at the two sides of the blocking member 58, so that a good blocking effect can be achieved, and the articles placed on the first inner cavity placing object 511 are further prevented from blocking the gap between the first inner cavity placing object 511 and the first side wall surface 22 and from falling from the gap between the first inner cavity placing object 511 and the first side wall surface 22.

Barrier and drainage structure

Please continue to refer to fig. 18 and 22. In an embodiment, the end of the first inner cavity member 511 close to the first sidewall 22 is provided with a flow guiding structure 57, and the flow guiding structure 57 has a flow guiding surface 571, the flow guiding surface 571 faces the first end wall 24 and also faces the first sidewall 22, so as to guide the cold air to be delivered along the first sidewall 22 to the second end wall 25 as far as possible.

Wherein the dam 58 is disposed proximate the first end edge 503 and the flow directing structure 57 is disposed on a side of the dam 58 proximate the first end edge 503. Specifically, the drainage structure 57 is disposed on a side of the dam 58 close to the first sidewall 22, and both the drainage structure 57 and the dam 58 are preferably disposed on the first inner chamber-placing member 511 close to the bottom of the ventilation groove 54, so as to ensure that the functions of the drainage structure 57 and the dam 58 are fulfilled. And the drainage structure 57 and the stopper 58 are integrally formed, which is beneficial to simplifying the structural design of the first inner cavity member 511 and facilitating the forming process of the first inner cavity member 511.

The side wall of the inner cavity body is matched with cold air backflow

Referring to fig. 23, fig. 23 is a schematic view of a fourth embodiment of a cross-sectional structure along a direction a-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. 23.

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. 23. 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 (the following return air guide protrusions 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 return air guide grooves 71 are 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 indicated by an arrow Y in fig. 2, the same applies hereinafter) 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. 24, fig. 24 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 gradually decreases in the direction 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. 24. 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. 25, fig. 25 is a schematic structural view of a return air duct according to a second embodiment 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. 26, fig. 26 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. 26. 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. 27 and 28, 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. 26.

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. 26 to fig. 28. 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 connecting member 231 are required to be disposed at the joint of the second sidewall 23 and the inner cavity device 50, the design of the sidewall ventilation structure 70 and the connecting member 231 is considered at the joint of the second sidewall 23 and the inner cavity device 50 in the embodiment of the present application.

Please continue to refer to fig. 26 and 27. 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 to realize the ventilation effect at 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.

Further, the surfaces of the return air guide protrusions 72 facing the inner cavity mount 50 are respectively provided with a connecting member 231 to ensure that the inner cavity mount 50 is reliably mounted and fixed on the second sidewall surface 23, which is beneficial to improving the overall reliability of the refrigeration equipment.

Object placing ventilation structure and side wall ventilation structure are matched to realize multi-path cold air backflow

Referring to fig. 26 to 29, fig. 29 is a partial schematic view of a C-C direction cross-sectional structure of the refrigeration apparatus shown in fig. 28.

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 item 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. 27. Also, FIG. 27 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. 27.

Please continue to refer to fig. 28 and 29. 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 means 50 is further provided with a third vent hole 63, the third vent hole 63 is provided in the other region of the inner chamber means 50 except for the region thereof sandwiched between the two connecting ribs 2311, and the third vent hole 63 is provided near 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. 28 and 29. 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. 30, fig. 30 is a schematic diagram of a third embodiment of a front view structure of the refrigeration apparatus 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 (the following air supply guide protrusions 82) are provided on the first side wall surface 22 of the inner cavity 20, the ribs protrude toward the inside of the inner cavity 20, and the 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. 31, fig. 31 is a schematic structural view of an air guiding duct 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. 32, fig. 32 is a schematic structural view of an air supply guiding gutter according to a second embodiment of the present application.

In one embodiment, the cross-sectional area of the air supply guide groove 81 gradually increases in a 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. 30. 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 protrusion 82 relatively close to the second side wall surface 23 guides the cold air to enter the air supply guide groove 81, so that as much cold air as possible enters the air supply guide groove 81 and is supplied through the air supply guide groove 81, and then is conveyed to the storage area of each inner cavity object 50 to refrigerate the stored object, i.e., the air supply guide groove 81 has a good air flow guide effect.

Referring to fig. 30 and 33, fig. 33 is a schematic view of a D-D cross-sectional structure of the refrigeration apparatus shown in fig. 30.

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, the air inlets 28 of the inner cavity 20 are sequentially spaced along the opposite direction of the two second side walls 23 of the inner cavity 20, and then the air inlets 28 respectively convey cold air to the air supply guiding grooves 81 on the first side wall 22, so that the amount of cold 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. 34 to 36, fig. 34 is a schematic view illustrating an eighth embodiment of a B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, fig. 35 is a schematic view illustrating a ninth embodiment of a B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, and fig. 36 is a schematic view illustrating a tenth embodiment of a 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 cold air to pass through in the joint between the first inner cavity member 511 and the first side wall surface 22.

Please continue to refer to fig. 34. 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 guiding groove 81, so that the area of the ventilation area at the position of the air supply guiding groove 81 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. 35. 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. 36. 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 guiding groove 81 of the first sidewall 22, and the wind guiding protrusion 82 of the first sidewall 22 is inserted into the ventilating 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 zone 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 zone 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 relatively close to the first end wall surface 24 and the first side wall surface 22 reaches the first inner cavity member 511 relatively close to the second end wall surface 25, part of the cold air is blocked by the first inner cavity member 511 relatively close to the second end wall surface 25 and flows toward the storage area of the first inner cavity member 511 relatively close to the first end wall surface 24, this allows the cool air transferred between the first inner chamber components 511 and the first sidewall 22 to be separately supplied to the storage area of each first inner chamber component 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. 34 to 36, 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 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, which means 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, and 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, and G3 and the first side wall surface 22 are S1, S2, and S3, where S1, S2, and S3 are decreased in an equal difference, and S3 is a tolerance, for example, S1: S2: S3 is 3:2: 1.

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 first inner cavity containing objects G1, G2, and G3 are sequentially disposed in the inner cavity 20 along the direction from the first end wall 24 to the second end wall 25 as shown in fig. 2, wherein S1 > S2 > S3, and S1-S2 > S2-S3, for example, S1: S2: S3 is 6:3:2, 4:2:1, and so on.

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.

Please continue to refer to fig. 2 and 3. In one embodiment, the cooling device 40 includes a heat exchanger 41 and a fan assembly 42, and the fan assembly 42 is disposed opposite the heat exchanger 41. The fan assembly 42 is used for generating a circulating airflow, and specifically, the airflow output by the fan assembly 42 circulates in the inner cavity 20 and then flows back to the heat exchanger 41 and the fan assembly 42. The heat exchanger 41 is used for absorbing heat carried by the airflow, and particularly, the heat of the airflow passing through the heat exchanger 41 is absorbed by the heat exchanger 41, so as to form cold air with lower temperature, so as to form cold air circulation to refrigerate and preserve articles stored in the inner cavity 20.

In one embodiment, the heat exchanger 41 and the fan assembly 42 are sequentially disposed in an opposing direction of the first endwall 24 and the second endwall 25. Specifically, the heat exchanger 41 may be disposed close to the second end wall surface 25 relative to the fan assembly 42, and the airflow output by the fan assembly 42 passes through the heat exchanger 41 to form low-temperature cold air, so as to be conveyed to the storage area of each inner cavity placement object 50; or the heat exchanger 41 is disposed close to the first end wall surface 24 relative to the fan assembly 42, and the returned air flow passes through the heat exchanger 41 to form low-temperature cool air, and then is delivered to the fan assembly 42, so that the low-temperature cool air is delivered to the storage area of each inner cavity device 50 by the fan assembly 42.

The volute 43 has an air inlet (not shown) through which the backflow airflow enters the volute 43 and reaches the fan 49, and an air outlet 431 through which the airflow output by the fan 49 is output to the inner cavity 20.

Alternatively, the fan 49 is preferably a centrifugal fan or the like, and is not limited thereto.

In one embodiment, the plurality of wind guiding grids includes a plurality of first wind guiding grids 44 sequentially arranged along the first direction at intervals. Specifically, the plurality of first air guiding grids 44 are sequentially arranged at intervals along the opposite direction of the two second side wall surfaces 23 of the inner cavity 20, and each first air guiding grid 44 extends along the same direction, and is used for guiding the air flow output by the fan to be conveyed along the direction perpendicular to the opposite direction of the two second side wall surfaces 23 of the inner cavity 20, so that the air flow output by the fan has a relatively long air supply distance in the opposite direction of the first end wall surface 24 and the second end wall surface 25 of the inner cavity 20, and further the air flow output by the fan is conveyed to the second end wall surface 25 as far as possible.

The first wind guiding grid 44 does not need to extend along a certain direction exactly, but the extending direction of the first wind guiding grid 44 is allowed to form a certain angle with the direction.

Further, the first air guiding grids 44 are disposed in parallel to each other, which is beneficial to improving the effect of guiding the air flow output by the fan to be conveyed in the direction from the first end wall surface 24 to the second end wall surface 25 in the opposite direction of the two second side wall surfaces 23 of the inner cavity 20. The first air guiding grid 44 is preferably in the form of a plate. The first wind-guiding grids 44 are arranged parallel to each other, which means that the planes in which the first wind-guiding grids 44 are arranged are parallel to each other.

Referring to fig. 39 and 40, fig. 39 is a schematic structural view of a second embodiment of the volute of the present application, and fig. 40 is a schematic structural view of a fifth embodiment of a sectional structure taken along a direction a-a of the refrigeration apparatus shown in fig. 1.

In one embodiment, the plurality of wind guiding grids includes a plurality of second wind guiding grids 45 sequentially arranged along the second direction at intervals. Specifically, the plurality of second air guiding grids 45 are sequentially arranged at intervals along the opposite direction of the article access opening 21 of the inner cavity 20 and the first side wall surface 22, and each second air guiding grid 45 extends along the same direction, specifically extends towards the first side wall surface 22, and is used for guiding the airflow output by the fan to flow towards the first side wall surface 22, so that the airflow output by the fan can flow along the first side wall surface 22 as far as possible, and further air is supplied through the gap between the first inner cavity article and the first side wall surface in the above embodiment.

The second wind-guiding grid 45 does not need to extend along a certain direction strictly, but the extending direction of the second wind-guiding grid 45 is allowed to form a certain angle with the direction.

Further, the second air guiding grids 45 are arranged in parallel, which is beneficial to improving the effect of guiding the air flow output by the fan to blow towards the first side wall surface 22. The second air guiding grid 45 is preferably in the form of a plate. The second wind-guiding grids 45 are arranged parallel to each other, which means that the planes in which the second wind-guiding grids 45 are arranged are parallel to each other.

Referring to fig. 37 to 41, fig. 41 is a schematic structural diagram of a third embodiment of the volute of the present application.

In one embodiment, the plurality of wind guide grids includes not only the first wind guide grids 44 but also the second wind guide grids 45. The plurality of first air guiding grids 44 are sequentially arranged at intervals along the opposing direction of the two second side wall surfaces 23 of the inner cavity 20, the plurality of second air guiding grids 45 are sequentially arranged at intervals along the opposing direction of the article access opening 21 and the first side wall surface 22 of the inner cavity 20, and the plurality of first air guiding grids 44 and the plurality of second air guiding grids 45 are arranged in a crisscross manner with each other.

Air deflector assembly

Referring to fig. 42, fig. 42 is a schematic view of a sixth embodiment of a sectional structure along the direction a-a of the refrigeration apparatus shown in fig. 1.

In one embodiment, the outlet 431 of the volute 43 includes a first edge 432 and a second edge 433, and the first edge 432 and the second edge 433 are disposed opposite to each other. The air outlet 431 is provided with an air deflector assembly. The air deflection assembly includes a first air deflection plate disposed at the first edge 432. The first air guiding plate comprises a first air guiding portion 46, and the first air guiding portion 46 is arranged obliquely towards the second edge 433.

Fig. 42 shows the case where the first wind-guiding plate only includes the first wind-guiding portion 46, and the first wind-guiding portion 46 is directly disposed on the first edge 432. In other embodiments of the present application, the first air guiding plate may further include other air guiding portions besides the first air guiding portion 46, which will be described in detail below.

Specifically, the first air guiding portion 46 is disposed at an edge of one side of the outlet 431, and the first air guiding portion 46 is disposed obliquely toward the other side of the outlet 431. Further, the first air guiding portion 46 is disposed at an edge of the air outlet 431 away from the first side wall surface 22, and the first air guiding portion 46 is disposed obliquely toward the first side wall surface 22, so that the air flow output from the air outlet 431 of the volute 43 flows toward the first side wall surface 22 of the inner cavity 20 under the guidance of the first air guiding portion 46 (the air flow flows toward the dashed arrow in fig. 42), which is beneficial to make the air flow output from the air outlet 431 of the volute 43 flow along the first side wall surface 22 as much as possible, and then form a circulating air flow.

Referring to fig. 43a and 43b, fig. 43a is a schematic structural view of a fourth embodiment of a volute of the present application, and fig. 43b is a schematic structural view of a seventh embodiment of a cross-section in a direction a-a of the refrigeration apparatus shown in fig. 1.

Further, the air deflection assembly also includes a second air deflection plate 47. The second air guiding plate 47 is disposed at the second edge 433, and the second air guiding plate 47 is disposed obliquely toward the first edge 432.

Specifically, the second air guiding plate 47 is disposed at the edge of the air outlet 431 away from the first air guiding portion 46, and the second air guiding plate 47 is disposed obliquely toward the first air guiding portion 46. Specifically, the second air deflector 47 is disposed at an edge of the air outlet 431 away from the storage opening 21, and the second air deflector 47 is disposed obliquely toward the storage opening 21, wherein the second air deflector 47 is configured to guide the air flow output from the air outlet 431 of the volute 43 to flow toward the first air guiding portion 46, so that the air flow output from the air outlet 431 of the volute 43 flows along the first air guiding portion 46 as far as possible, and then flows toward the first side wall surface 22 of the inner cavity 20 under the guidance of the first air guiding portion 46, which is further beneficial to make the air flow output from the air outlet 431 of the volute 43 flow along the first side wall surface 22 as far as possible.

Further, the first air guiding plate further includes a second air guiding portion 48 disposed at the air outlet 431 of the volute 43. The first edge 432 and the first air guiding portion 46 are connected by the second air guiding portion 48, and the second air guiding plate 47 is disposed to be inclined toward the second air guiding portion 48.

Specifically, the second air guiding portion 48 extends along the opposite direction of the first end wall surface 24 and the second end wall surface 25 of the inner cavity 20, the second air guiding portion 48 is disposed at the edge of the air outlet 431 close to the object storage opening 21, and the second air guiding portion 48 is further connected to the first air guiding portion 46, so that the first air guiding portion 46 is disposed at the edge of the air outlet 431 relatively close to the object storage opening 21. It can be seen that, the second air guiding portion 48 is disposed such that the air flow output from the air outlet 431 of the volute 43 flows a certain distance along the direction from the first end wall surface 24 to the second end wall surface 25 of the inner cavity 20, and then reaches the first air guiding portion 46, and further flows toward the first side wall surface 22 of the inner cavity 20 under the guidance of the first air guiding portion 46, which is beneficial to improving the guiding effect of the air flow, and is further beneficial to making the air flow output from the air outlet 431 of the volute 43 flow along the first side wall surface 22 as far as possible.

The second air guiding plate 47 is disposed opposite to the second air guiding portion 48, wherein the second air guiding plate 47 guides the airflow output from the air outlet 431 of the volute 43 to flow toward the second air guiding portion 48, so that the airflow flows along the second air guiding portion 48 to the first air guiding portion 46, and further flows along the first air guiding portion 46 toward the first side wall surface 22 of the inner cavity 20.

In addition, in the present embodiment, the first air guiding portion 46, the second air guiding plate 47 and the second air guiding portion 48 are matched to reduce the size of the passage provided by the air guiding plate assembly for the air flow to pass through, i.e. the air flow output from the air outlet 431 of the volute 43 flows toward the first air guiding portion 46 more intensively, which is beneficial to improving the flow velocity of the air flow, and based on the coanda effect, the air flow can flow more depending on the first air guiding portion 46, and the subsequent air flow flows more depending on the first sidewall surface 22.

The dashed arrows in fig. 43b show the flow direction of the airflow output from the air outlet 431 of the volute 43 guided by the first air guiding portion 46, the second air guiding plate 47 and the second air guiding portion 48.

Note that the air guide plate assembly including the first air guide portion 46, the second air guide plate 47, and the second air guide portion 48 is provided at the edge of the outlet 431, and is located on the outer periphery of the air guide grid including the first air guide grid 44 and the second air guide grid 45. Specifically, the first air guiding grid 44 and the second air guiding grid 45 are provided between the second air guiding plate 47 and the second air guiding portion 48.

In this way, the airflow output from the outlet 431 is guided by the air guide plate assemblies under the guidance of the first air guide grids 44 and the second air guide grids 45, so that the guiding effect of the airflow output from the outlet 431 is improved to the maximum extent.

Specifically, in the above embodiment, the plurality of second wind-guiding grids 45 sequentially arranged at intervals along the opposing direction of the first edge 432 and the second edge 433, that is, the plurality of second wind-guiding grids 45 sequentially arranged at intervals along the opposing direction of the article access opening 21 and the first side wall surface 22 of the inner cavity 20, can guide the airflow to the first wind-guiding portion 46, so that the airflow output from the wind outlet 431 of the volute 43 flows along the first wind-guiding portion 46 as much as possible, and further flows toward the first side wall surface 22 of the inner cavity 20 under the guidance of the first wind-guiding portion 46, which is further beneficial for allowing the airflow output from the wind outlet 431 of the volute 43 to flow along the first side wall surface 22 as much as possible. This can be achieved by the plurality of second wind-guiding grids 45 being arranged obliquely to the first edge 432.

Please continue to refer to fig. 43a and 43 b. In one embodiment, the orthographic projections of the first wind-guiding portion 46, the second wind-guiding portion 48 and the second wind-guiding plate 47 on the plane defined by the first edge 432 and the second edge 433 cover the orthographic projection of the wind outlet 431 of the volute 43 on the plane defined by the first edge 432 and the second edge 433. That is to say, the first air guiding portion 46, the second air guiding portion 48 and the second air guiding plate 47 cover the air outlet 431 of the volute 43, so that the risk that foreign matters fall into the volute 43 can be reduced to the maximum extent, and the reliability of the refrigeration apparatus of the present embodiment can be ensured as much as possible.

The refrigerating plant is externally arranged

Please continue to refer to fig. 30 and fig. 33. 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.
