The refrigeration equipment further comprises a door body 30 rotatably connected with the main shell 10, wherein the door body 30 is used for being in butt joint with the storage and taking port 21 of the inner cavity 20, and further after the door body 30 rotates to be in butt joint with the storage and taking port 21 of the inner cavity 20, namely the door body 30 is closed, so that a closed space is formed inside the inner cavity 20, and the refrigeration effect of articles stored inside the inner cavity 20 is ensured; after the door 30 is rotated to the storage opening 21 far from the inner cavity 20, i.e., the door 30 is opened, the inner space of the inner cavity 20 is opened to the user, and the user can store or take out the desired article through the storage opening 21.

The refrigeration apparatus also includes a refrigeration device 40. The refrigerating device 40 is used for providing cold air circulation for the internal storage space of the inner cavity 20 so as to exchange heat between the cold air with the articles stored in the inner cavity 20 through the cold air with a lower temperature, thereby realizing efficient refrigeration of the articles stored in the inner cavity 20.

Internal cavity structure

Referring to fig. 2 and 3, fig. 3 is a schematic diagram showing a first embodiment of a front view structure of the refrigeration apparatus shown in fig. 1. Wherein the door body is omitted in fig. 3.

In one embodiment, the inner cavity 20 has a first side wall 22 opposite to the access opening 21 and a second side wall 23 connecting the access opening 21 and the first side wall 22, respectively. The first side wall surface 22 and the second side wall surface 23 are side inner walls of the inner chamber 20. Specifically, the inner cavity 20 has two opposite second side wall surfaces 23, and as shown in fig. 3, each second side wall surface 23 is connected to the access opening 21 and the first side wall surface 22, respectively.

The inner cavity 20 further has a first end wall surface 24 and a second end wall surface 25 disposed opposite to each other, and the first end wall surface 24 is adjacent to the access opening 21, the first side wall surface 22, and the second side wall surface 23, respectively, and the second end wall surface 25 is adjacent to the access opening 21, the first side wall surface 22, and the second side wall surface 23, respectively. The first end wall surface 24 and the second end wall surface 25 correspond to the top and the bottom of the inner cavity 20, respectively, and specifically, the first end wall surface 24 may be a top inner wall of the inner cavity 20 and the second end wall surface 25 may be a bottom inner wall of the inner cavity 20, or the second end wall surface 25 may be a top inner wall of the inner cavity 20 and the first end wall surface 24 may be a bottom inner wall of the inner cavity 20.

Wherein, fig. 4 and 5 omit the door body.

In one embodiment, the refrigeration appliance may be provided with a plurality of internal chambers 20. For example, the inner cavity 20 includes a first inner cavity 26 and a second inner cavity 27. The first interior cavity 26 and the second interior cavity 27 are independent of each other and are each used for storing items. In particular, one of the first inner chamber 26 and the second inner chamber 27 may serve as a refrigerating chamber of a refrigerating apparatus, and the other may serve as a freezing chamber of the refrigerating apparatus.

The first inner chamber 26 and the second inner chamber 27 can be provided with a cold air circulation by the same refrigerating device 40 for refrigerating preservation, so that the number of the refrigerating devices 40 in the refrigerating equipment with a plurality of inner chambers 20 can be reduced, which is beneficial to reducing the production cost of the refrigerating equipment and simplifying the design of the refrigerating equipment. While the first inner chamber 26 and the second inner chamber 27 may also be provided with a cold air circulation by different cooling devices 40, respectively, this is advantageous for simplifying the control of the cooling air circuit of the cooling device 40 and for avoiding disturbances of the temperature between the different inner chambers 20, with respect to the case where one cooling device 40 provides cold air to a plurality of inner chambers 20.

Further, the first inner cavity 26 and the second inner cavity 27 may be stacked in the height direction of the refrigeration apparatus, as shown in fig. 4; or the first inner cavity 26 and the second inner cavity 27 are disposed side by side in the horizontal direction when the refrigeration apparatus is properly placed, as shown in fig. 5, without limitation.

Of course, in other embodiments of the present application, the plurality of inner cavities 20 included in the refrigeration apparatus may each be used as a refrigerating chamber of the refrigeration apparatus, or each may be used as a freezing chamber of the refrigeration apparatus, which is not limited herein.

Object placed in inner cavity

Please continue to refer to fig. 2 and 3. In one embodiment, to reasonably plan and utilize the internal storage space of the inner cavity 20, the refrigeration apparatus further includes a plurality of internal cavity placement objects 50, where the plurality of internal cavity placement objects 50 are disposed in the inner cavity 20 to divide the inner cavity 20 into a plurality of compartments, each for storing an article.

Alternatively, the internal cavity placement object 50 may be a shelf, drawer, or the like, without limitation.

Specifically, the inner cavity article 50 includes a first side edge 501 and a second side edge 502, the first side edge 501 and the second side edge 502 are disposed opposite to each other, and the first side edge 501 and the second side edge 502 are specifically side edges of the inner cavity article 50 adjacent to the two second side wall surfaces 23 of the inner cavity 20 after the inner cavity article 50 is mounted to the inner cavity 20.

The inner cavity object 50 further includes a first end edge 503 and a second end edge 504, where the first end edge 503 and the second end edge 504 are disposed opposite to each other, and the first end edge 503 is specifically an end edge of the inner cavity object 50 near the first sidewall 22 of the inner cavity 20 after the inner cavity object 50 is mounted on the inner cavity 20, and the second end edge 504 is specifically an end edge of the inner cavity object 50 near the access opening 21 of the inner cavity 20 after the inner cavity object 50 is mounted on the inner cavity 20.

The inner cavity article 50 further includes a first surface 505 and a second surface 506, the first surface 505 and the second surface 506 facing away from each other, and the first surface 505 is specifically a surface of the inner cavity article 50 proximate to the first end wall surface 24 of the inner cavity 20 after the inner cavity article 50 is mounted to the inner cavity 20, and the second surface 506 is specifically a surface of the inner cavity article 50 proximate to the second end wall surface 25 of the inner cavity 20 after the inner cavity article 50 is mounted to the inner cavity 20.

Door body object

Please continue to refer to fig. 2. In this embodiment, the refrigeration apparatus further includes a plurality of door-mounted objects 31, and the plurality of door-mounted objects 31 are disposed on the door 30. The docking of the door 30 with the inner cavity 20 may specifically be: after the door body 30 is closed, the door body object 31 on the door body 30 is embedded into the inner cavity 20 through the object storing and taking port 21, so that the objects stored by the door body object 31 are refrigerated and preserved; after the door 30 is opened, the door object 31 is moved away from the inner cavity 20 along with the rotation of the door 30, so that a user can store or take out a desired object at the door object 31.

Alternatively, the door mount 31 may be a bottle frame or the like, which is not limited herein.

Complete machine air path circulation

Please continue to refer to fig. 2 and 3. In one embodiment, the cooling device 40 outputs cool air to the interior of the inner cavity 20 in a direction from the first end wall 24 to the second end wall 25 (as indicated by arrow Z in fig. 2 and 3, the same applies below), i.e., the cooling device 40 outputs cool air toward the second end wall 25. The plurality of inner cavity articles 50 in the inner cavity 20 are disposed in spaced relation between the first end wall 24 and the second end wall 25. Specifically, the plurality of inner cavity articles 50 are sequentially spaced apart from each other in the inner cavity 20 along the direction from the first end wall surface 24 to the second end wall surface 25, so as to divide the inner storage space of the inner cavity 20 into a plurality of compartments along the direction from the first end wall surface 24 to the second end wall surface 25.

The plurality of inner cavity placement pieces 50 in the inner cavity 20 cooperate with the first side wall 22 to form a gap for ventilation, and in particular, the inner cavity placement pieces 50 may be spaced apart from the first side wall 22 to form the gap. The cold air input into the inner cavity 20 by the refrigerating device 40 flows along the first side wall 22 of the inner cavity 20 by using the Coanda Effect (Coanda Effect), and then is supplied through the gap between the inner cavity placement object 50 and the first side wall 22, so that the cold air reaches the storage area of each inner cavity placement object 50, so as to refrigerate the objects stored in the storage area of each inner cavity placement object 50, and then flows back to the refrigerating device 40 at least through the gap between each inner cavity placement object 50 and the door 30, thereby realizing cold air circulation. 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 object 50 may be used 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 refrigeration efficiency and the refrigeration effect, as 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 object 50 is an area of each inner cavity object 50 for placing objects, specifically, an area of the inner cavity object 50 facing the top of the inner cavity 20.

Specifically, when the cold air input into the inner cavity 20 by the refrigerating device 40 reaches a certain flow rate, the cold air input into the inner cavity 20 by the refrigerating device 40 flows along the first side wall 22 of the inner cavity 20 based on the coanda effect, wherein the specific principle of the coanda effect is within the understanding scope of those skilled in the art, and will not be described herein.

Further, after the door 30 is closed, the door placement object 31 on the door 30 is spaced from the inner cavity placement object 50 in the inner cavity 20, and the cool air flows back to the refrigerating device 40 at least through the gap between the inner cavity placement object 50 and the door placement object 31, as shown in fig. 2.

That is, the refrigerating apparatus 40 of the present embodiment is beneficial to improve the refrigerating effect and the refrigerating efficiency by providing the cold air circulation to the internal storage space of the inner cavity 20 to perform the circulation refrigeration to the articles stored in the internal storage space of the inner cavity 20.

The refrigerating apparatus 40 of the present embodiment directly outputs cold air into the inner cavity 20, and supplies air to the storage areas of the articles 50 in the respective inner cavities by the cold air flowing along the first side wall 22 of the inner cavity 20. This is different from the prior art in that the cooling device inputs cold air into the internal storage space of the internal cavity through the air duct assembly arranged outside the internal cavity, and the conventional air duct assembly needs to be provided with ventilation structures corresponding to the storage areas of the objects placed in the respective internal cavities respectively so as to transmit the cold air to the storage areas corresponding to the objects placed in the internal cavities.

In this way, the refrigeration equipment of the embodiment omits the traditional air duct assembly, which is beneficial to reducing the production cost of the refrigeration equipment. In addition, the design of the traditional air duct component is omitted, the wind resistance in the system is reduced, the air quantity is improved, and the refrigerating device 40 of the embodiment allows the rotation speed of the fan to be reduced under the same air quantity requirement, so that the energy consumption 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 with larger volume, namely the inner storage space of the inner cavity 20 is designed with larger volume. In addition, the refrigerating equipment omits the design of the traditional air duct component, and radically solves the problems of condensation, frosting, air duct blockage caused by icing in the air duct and the like of the traditional air duct component.

In one embodiment, the inner cavity placement member 50 comprises a first inner cavity placement member 511 and a second inner cavity placement member 512, as shown in FIG. 3. The refrigeration unit 40 is disposed adjacent the first end wall 24 and the first interior cavity placement member 511 is disposed in the region between the refrigeration unit 40 and the second end wall 25. Specifically, the first inner cavity object 511 is spaced from the first side wall 22, and the cool air input into the inner cavity 20 by the cooling device 40 is blown through the gap between the first inner cavity object 511 and the first side wall 22. The second inner cavity object 512 is disposed corresponding to the refrigerating device 40, and is correspondingly disposed in the area between the first inner cavity object 511 and the first end wall 24, and the returned cold air passes through the storage area of the second inner cavity object 512 to refrigerate the articles stored in the storage area of the second inner cavity object 512 and then flows back to the refrigerating device 40. The number of the first inner cavity placement object 511 and the second inner cavity placement object 512 may be plural.

The inner cavity is matched with cold air for backflow

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

In one embodiment, the inner cavity placement object 50 (including the first inner cavity placement object 511 and the second inner cavity placement object 512 described in the above embodiments, as shown in fig. 3) is provided with a plurality of placement object ventilation structures 60, and the cold air may flow back through the placement object ventilation structures 60 on the inner cavity placement object 50. That is, on the basis that the cold air is returned through the gaps between the respective inner cavity placement articles 50 and the door body 30, a return path of the cold air is increased, thereby being advantageous to increase a diffusion range of the cold air, i.e., to make a coverage range of the cold air wider, thereby being advantageous to improve a cooling efficiency and a cooling effect.

Specifically, a portion of the cool air sent into the storage area corresponding to each inner cavity object 50 flows back through the gap between the inner cavity object 50 and the door 30, and a portion of the cool air flows down to the storage area of the inner cavity object 50 relatively close to the first end wall 24 through the object ventilation structure 60 on the inner cavity object 50, and then flows back to the refrigeration device 40, wherein the circulation direction of the cool air is shown by the dotted arrow in fig. 2.

Alternatively, the object-placing ventilation structure 60 may be a through hole or a through slot structure, so as to allow the cool air in the storage area corresponding to the object-placing object 50 in each inner cavity to sink to the storage area of the object-placing object 50 relatively close to the first end wall 24 through the object-placing ventilation structure 60 on the object-placing object 50, and then flow back to the refrigerating device 40.

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 much 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 as much as possible, and the cool air flows back through the gap between the inner cavity object 50 and the door 30 and the object ventilation structure 60 on the inner cavity object 50 after reaching the second end wall surface 25. Of course, during the transfer of the cool air along the first side wall surface 22 to the second end wall surface 25, the cool air inevitably passes to the storage area of each of the inner cavity placement articles 50 when reaching the position of each of the inner cavity placement articles 50.

Ventilation structure for article

The following describes the position of the object placement ventilation structure 60 on the inner cavity object placement 50.

Please continue to refer to fig. 6. In one embodiment, the plurality of object-placing ventilation structures 60 on the inner cavity-placing object 50 are disposed on a portion of the inner cavity-placing object 50 near the second side wall surface 23 of the inner cavity 20. Specifically, the inner cavity 20 has two opposite second side wall surfaces 23, and the object ventilation structure 60 is disposed on at least one of two opposite sides of the object 50 near the two second side wall surfaces 23 for matching with the back flow of the cold air.

Fig. 6 shows the case where the object-placing ventilation structure 60 is provided on opposite sides of the inner cavity object 50 adjacent to the two second sidewall surfaces 23, respectively, by way of example only, and not by way of limitation.

Please continue to refer to fig. 7. In an alternative embodiment, the plurality of object ventilation structures 60 on the inner cavity object 50 are disposed at the portion of the inner cavity object 50 near the first side wall 22, so that a portion of the cold air fed into the storage area of each inner cavity object 50 flows in a direction away from the first side wall 22, and a portion of the cold air flows back through the object ventilation structures 60 on the inner cavity object 50 near the first side wall 22, thereby increasing the cold air backflow path near the first side wall 22, thereby facilitating the increase of the diffusion range of the cold air, widening the coverage range of the cold air, and facilitating the improvement of the refrigeration efficiency and the refrigeration effect.

Please continue to refer to fig. 8. In another alternative embodiment, the plurality of object-placing ventilation structures 60 on the inner cavity-placing object 50 are disposed at a portion of the inner cavity-placing object 50 away from the first side wall 22, that is, the object-placing ventilation structures 60 are disposed at a portion of the inner cavity-placing object 50 near the object-storing 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 object 50 can flow back through the gap between the inner cavity object 50 and the door body, and a part of the cold air can flow back through the object ventilation structure 60 on the inner cavity object 50 at a position far away from the first side wall surface 22, so that a cold air backflow path is increased, the diffusion range of the cold air is further increased, the coverage range of the cold air is wider, and the refrigerating efficiency and the refrigerating effect are improved.

It should be understood that, in the foregoing embodiment, whether the object-placing ventilation structure 60 is disposed on a portion of the inner cavity-placing object 50 near the second side wall surface 23 of the inner cavity 20 (as shown in fig. 6), or whether the object-placing ventilation structure 60 is disposed on a portion of the inner cavity-placing object 50 near or far from the first side wall surface 22 (as shown in fig. 7 and 8), the object-placing ventilation structure 60 is disposed at an edge position on the inner cavity-placing object 50, and tends to deviate from an area of the inner cavity-placing object 50 where a user is usually used to place objects, so as to avoid blocking a cold air backflow path at the inner cavity-placing object 50 by the objects stored on the inner cavity-placing object 50 as much as possible.

Please continue to refer to fig. 9. In yet another alternative embodiment, the article-placement ventilation structures 60 are evenly distributed over the inner cavity-placement articles 50, i.e., the portion of the inner cavity-placement articles 50 that is proximate to the second sidewall surface 23 of the inner cavity 20 and the portion of the inner cavity-placement articles 50 that is proximate to and distal from the first sidewall surface 22, even the area of the inner cavity-placement articles 50 where a user is typically used to place articles are provided with the article-placement ventilation structures 60.

By the above way, the cold air backflow path on the inner cavity object 50 is increased as much as possible, so that even if part of the cold air backflow path is blocked by the objects stored on the inner cavity object 50, the cold air backflow path provided by the object ventilation structure 60 in other areas on the inner cavity object 50 can be ensured to normally backflow, and further the cold air is ensured to have 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 an embodiment, in order to ensure that the inner cavity-shaped articles 50 relatively close to the second end wall surface 25 can return enough cool air to the storage area of the inner cavity-shaped articles 50 relatively close to the first end wall surface 24, and further ensure the cooling effect of the articles stored in the storage area of each inner cavity-shaped article 50, the total ventilation area of the article ventilation structures 60 on each inner cavity-shaped article 50 (i.e. the sum of the ventilation areas of each article ventilation structure 60 on each inner cavity-shaped article 50) gradually increases along the direction from the first end wall surface 24 to the second end wall surface 25.

It should be noted that the number of the object-placing ventilation structures 60 included in the inner cavity object 50 per unit area and the size of the object-placing ventilation structure 60 alone determine the ventilation area of the object-placing ventilation structure 60 on the inner cavity object 50.

The dimensional relationships between the object-placement ventilation structures 60 of the different interior cavity object placement 50 are described below.

Please continue to refer to fig. 10a. In an embodiment, under the condition that the distribution density of the object-placing ventilation structures 60 of each inner cavity-placing object 50 (i.e. the number of object-placing ventilation structures 60 contained in each inner cavity-placing object 50 per unit area) is the same, the ventilation area of the object-placing ventilation structure 60 of each inner cavity-placing object 50 gradually increases along the direction from the first end wall surface 24 to the second end wall surface 25, so that the inner cavity-placing object 50 relatively close to the second end wall surface 25 ensures that enough cold air flows back to the storage area of the inner cavity-placing object 50 relatively close to the first end wall surface 24, and further ensures the refrigerating effect of the objects stored in the storage area of each inner cavity-placing object 50.

It is understood that the ventilation area of the object-placement ventilation structure 60 may be represented by the cross-sectional area of the object-placement ventilation structure 60. Particularly when the cross-sectional shape of the object-placement ventilation structure 60 is circular, i.e., the object-placement ventilation structure 60 is a circular through-hole or through-slot, the ventilation area of the object-placement ventilation structure 60 may be represented by the cross-sectional diameter or radius of the object-placement ventilation structure 60.

The relationship of the distribution density between the object placement ventilation structures 60 of the different interior cavity objects 50 is described below.

Please continue to refer to fig. 10a. In an embodiment, in the case that the ventilation areas of the single article-placing ventilation structures 60 of the inner cavity-placing articles 50 are the same, the distribution density of the article-placing ventilation structures 60 of the inner cavity-placing articles 50 gradually increases along the direction from the first end wall surface 24 to the second end wall surface 25, so that the inner cavity-placing articles 50 relatively close to the second end wall surface 25 ensure sufficient backflow of cold air to the storage areas of the inner cavity-placing articles 50 relatively close to the first end wall surface 24, thereby ensuring the refrigerating effect of the articles stored in the storage areas of the inner cavity-placing articles 50.

Please continue to refer to fig. 10b. In one embodiment, the inner cavity placement article 50 includes a first sub-placement article 531 and a second sub-placement article 532 that are stacked. The object-placing ventilation structure 60 on the first sub-object 531 includes a plurality of first sub-ventilation structures 61, and the object-placing ventilation structure 60 on the second sub-object 532 includes a plurality of second sub-ventilation structures 62, where the first sub-ventilation structures 61 and the second sub-ventilation structures 62 are disposed corresponding to each other.

The first sub-set object 531 and the second sub-set object 532 are disposed to be capable of moving with respect to each other, so that the first sub-ventilation structure 61 and the second sub-ventilation structure 62 disposed correspondingly are capable of moving with respect to each other, so as to adjust the overlapping area of orthographic projections of the first sub-ventilation structure 61 and the second sub-ventilation structure 62 disposed correspondingly on the reference plane (as shown by the plane α in fig. 10 b), and thus adjust the total ventilation area of the object ventilation structure 60 disposed on the inner cavity object 50 composed of the first sub-set object 531 and the second sub-set object 532.

It should be noted that the reference plane is perpendicular to the stacking direction of the first sub-mount 531 and the second sub-mount 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 overlapping portion of the orthographic projection of the first 61 and second 62 sub-ventilation structures on the reference plane for ventilation. Thus, when the first sub-ventilation structure 61 and the second sub-ventilation structure 62 relatively move to the position where the two are in orthographic projection coincidence on the reference plane, the ventilation area of the object ventilation structure 60 placed on the object 50 placed in the cavity is maximized; and when the first sub-ventilation structure 61 and the second sub-ventilation structure 62 are offset from each other such that there is no overlap in the orthographic projection of the two on the reference plane, the inner cavity placement object 50 does not have a ventilation function.

Of course, in other embodiments of the present application, the inner cavity placement object 50 may include a greater number of sub-placement objects, and is not limited to the first sub-placement object 531 and the second sub-placement object 532 described above, but is not limited thereto.

Form of ventilation structure for articles

In one embodiment, the object-placement ventilation structure 60 is disposed through the interior cavity object 50. Specifically, the object-placing ventilation structure 60 may be a hole structure formed on the inner cavity object 50, as shown in fig. 6 to 10a and 10 b; alternatively, the edge of the inner cavity object 50 is recessed toward the inner cavity object 50 to form the object ventilation structure 60 in the form of a groove, as shown in fig. 18, which can be applied to the case where the object ventilation structure 60 is disposed at the edge position on the inner cavity object 50 in the above embodiment.

Referring to fig. 11, fig. 11 is a schematic structural view of a first embodiment of the cavity placement object in the present application.

In an alternative embodiment, the inner cavity placement member 50 includes a plurality of support bars 52 disposed in a cross arrangement, the plurality of support bars 52 intersecting one another to form a net-like inner cavity placement member 50, wherein the net-like inner cavity placement member 50 has openings therein that are the placement member ventilation structure 60.

Referring to fig. 12, fig. 12 is a schematic structural view of a second embodiment of the cavity placement object in the present application.

In another alternative embodiment, the inner cavity placement object 50 includes a first sub-placement object 531 and a second sub-placement object 532 that are stacked, the first sub-placement object 531 includes a plurality of first support bars 521 extending in the same direction, the second sub-placement object 532 includes a plurality of second support bars 522 extending in the same direction, and the extending directions of the first support bars 521 and the second support bars 522 are different, so that the first support bars 521 and the second support bars 522 are disposed in a crossing manner in the stacking direction of the first sub-placement object 531 and the second sub-placement object 532, thereby forming a net-shaped inner cavity placement object 50, wherein the net holes on the net-shaped inner cavity placement object 50 are the placement object ventilation structure 60.

Of course, in other embodiments of the present application, the form of the object-placement ventilation structure 60 is not limited to that described above, but is not limited thereto.

Ventilation groove

Referring to fig. 13, fig. 13 is a schematic diagram showing 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 503 of the first inner cavity object 511 is provided with a plurality of wind shielding protrusions 55, and ventilation grooves 54 are formed between adjacent wind shielding protrusions 55.

Specifically, the edge of the first inner cavity object 511, which is close to the first side wall 22, is recessed in a 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 play a role in ventilation, so as to facilitate adjustment of the amount of cool air passing through the gap between the first inner cavity object 511 and the first side wall 22 per unit time. Also, due to the presence of the wind shielding protrusion 55, the risk of the article placed on the first interior cavity placement article 511 falling from the gap between the first interior cavity placement article 511 and the first side wall surface 22 can be reduced.

The adjacent ventilation grooves 54 are wind shielding protrusions 55 protruding toward the direction close to the first side wall surface 22 relative to the ventilation grooves 54, and the wind shielding protrusions 55 are used for adjusting the amount of cold air passing through the gap between the first inner cavity object 511 and the first side wall surface 22 in unit time in cooperation with the ventilation grooves 54. Also, the ventilation grooves 54 and the wind shielding projections 55 are alternately arranged one by one in the opposite directions of the two second side wall surfaces 23 of the inner chamber 20.

Of course, it is also understood that the edge of the first inner cavity placement object 511 near the first side wall surface 22 is provided with a plurality of wind shielding protrusions 55 protruding toward the first side wall surface 22, and ventilation grooves 54 are formed between adjacent wind shielding protrusions 55, which is not limited herein.

Further, the width of the slot opening of the ventilation groove 54 is preferably larger than the width of the slot bottom thereof, so as to facilitate injection molding of the ventilation groove 54, i.e. to facilitate the preparation process of the ventilation groove 54 on the first cavity placement object 511. The width of the slot and the slot bottom of the ventilation groove 54 is understood to be the length of both in the opposite direction of the two second side wall surfaces 23 of the inner cavity 20.

Please continue to refer to fig. 13. In an embodiment, the wind shielding protrusion 55 of the first inner cavity object 511 near the edge of the first side wall 22 abuts against the first side wall 22, and the ventilation groove 54 and the first side wall 22 form a gap in a matching manner for passing the cold air flowing along the first side wall 22 and further delivering the cold air to the second end wall 25. In this way, the ventilation groove 54 plays a role in ventilation, so that the ventilation groove 54 and the first side wall 22 are matched and surrounded to form a smaller gap, and the objects stored on the first inner cavity object 511 can be prevented from falling from the gap between the first inner cavity object 511 and the first side wall 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 object 511 near the edge of the first side wall 22 may be separately disposed from the first side wall 22 to form a gap for passing the cool air.

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

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

In one embodiment, the connection between the second side wall 23 of the inner cavity 20 and the inner cavity placement member 50 is provided with a plurality of side wall ventilation structures 70, and the cold air may flow back through the side wall ventilation structures 70. That is, on the basis that the cold air flows back through the gaps between the objects placed in the respective cavities and the door body in the above embodiment, the back flow path of the cold air is increased, so that the diffusion range of the cold air is advantageously increased, that is, the coverage range of the cold air is wider, and further, the refrigeration efficiency is advantageously improved and the refrigeration effect is improved.

Specifically, a portion of the cold air fed into the storage area corresponding to each inner cavity placement object 50 flows back through the gap between the inner cavity placement object 50 and the door 30, and a portion of the cold air flows down to the storage area of the inner cavity placement object 50 relatively close to the first end wall surface 24 through the side wall ventilation structure 70, and flows back to the refrigerating device 40. Wherein the flow of cool air at the sidewall ventilating structure 70 is shown by the dashed arrows in fig. 14.

It should be noted that, the cooling device 40 of the present embodiment is configured to deliver the cool air to the second end wall surface 25 as much 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 as much as possible, and the cool air flows back through the gap between the inner cavity object 50 and the door 30 and the side wall ventilation structure 70 after reaching the second end wall surface 25. Of course, during the transfer of the cool air along the first side wall surface 22 to the second end wall surface 25, the cool air inevitably passes to the storage area of each of the inner cavity placement articles 50 when reaching the position of each of the inner cavity placement articles 50.

Side wall ventilation structure

Please continue to refer to fig. 14. In one embodiment, the side wall ventilation structure 70 includes a flow guide channel structure, namely a return air flow guide channel 71, extending in the opposite direction of the first end wall 24 and the second end wall 25. The cool air may be returned through the return air guide duct 71 in a direction from the second end wall 25 to the first end wall 24.

Specifically, the second side wall surface 23 of the inner cavity 20 may be recessed away from the inner cavity object 50 to form a return air guide groove 71; or, a rib (i.e., a return air guide protrusion 72 described below) is disposed on the second side wall 23 of the inner cavity 20, the rib protrudes in a direction close to the object 50 disposed in the inner cavity, and a return air guide groove 71 is formed between adjacent ribs.

The number of the air return guide grooves 71 is preferably plural, and the plurality of air return guide grooves 71 are sequentially arranged at intervals along the opposite direction (as indicated by arrow Y in fig. 2, the same applies below) between the storage opening 21 of the inner cavity 20 and the first side wall 22, and the air return guide protrusions 72 are relatively protruding between the adjacent air return guide grooves 71. The return air guide grooves 71 and the return air guide protrusions 72 are alternately arranged one by one along the opposite direction of the storage opening 21 and the first side wall 22.

It should be noted that, in this embodiment, the return air guide groove 71 is preferably formed between the adjacent return air guide protrusions 72 by providing the return air guide protrusions 72 protruding toward the interior of the inner cavity 20 with respect to the second side wall surface 23 on the second side wall surface 23 of the inner cavity 20. In this way, 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 by the concave manner of the second side wall surface 23 requires the cold air to sink into the return air guide groove 71 to be guided by the return air guide groove 71 is avoided, and the realization of the guide function of the return air guide groove 71 and the improvement of the guide effect of the cold air are facilitated.

Referring to fig. 15, fig. 15 is a schematic structural diagram of a first embodiment of a return air guiding slot according to the present application.

In an embodiment, the cross-sectional area of the return air guiding groove 71 gradually decreases along 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 guiding 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 guiding groove 71 and flows back through the return air guiding groove 71, and further the return air guiding groove 71 has good backflow effect and high backflow efficiency.

Please continue to refer to fig. 15. In an embodiment, the plurality of return air guide grooves 71 on the second side wall surface 23 are radially disposed towards the second end wall surface 25, so that the cool air to be returned, which is close to the second end wall surface 25, enters the return air guide grooves 71 as much as possible and flows back through the return air guide grooves 71, and further the return air guide grooves 71 have good return effect and higher return efficiency.

Referring to fig. 16, fig. 16 is a schematic structural diagram of a second embodiment of a return air guiding slot according to the present invention.

In an embodiment, the distance between the end of each return air guiding protrusion 72 on the second side wall surface 23 near the second end wall surface 25 and the second end wall surface 25 gradually decreases from the middle to the direction near the access opening 21 of the inner cavity 20 and the first side wall surface 22. This means that the closer to the access opening 21 and the first side wall 22 the return air guide projection 72 has a smaller distance between the end thereof closer to the second end wall 25 and the second end wall 25, and the further from the access opening 21 and the first side wall 22 the return air guide projection 72 has a larger distance between the end thereof closer to the second end wall 25 and the second end wall 25.

Through the above manner, the air return guide protrusions 72 relatively close to the storage opening 21 and the first side wall 22 guide the cold air to enter the air return guide groove 71, so that as much cold air as possible enters the air return guide groove 71 and flows back through the air return guide groove 71, and further the air return guide groove 71 has a good backflow effect and a high backflow 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 embodiment, and is not limited herein.

Side wall ventilation structure and connecting piece

Referring to fig. 17, fig. 17 is a schematic diagram showing a second embodiment of a front view structure of the refrigeration apparatus shown in fig. 1.

In one embodiment, the inner cavity placement member 50 is secured to the second sidewall surface 23 by mounting, thereby securing the relative position of the inner cavity placement member 50 within the inner cavity 20 to perform its function of storing items. Correspondingly, the second side wall surface 23 is provided with a connecting piece 231 for connecting the inner cavity object 50, so that the inner cavity object 50 is mounted and fixed on the second side wall surface 23.

Specifically, two opposite sides of the inner cavity object 50 are respectively close to two opposite second side wall surfaces 23 of the inner cavity 20, and after two ends of the inner cavity object 50 close to the second side wall surfaces 23 are respectively mounted on the corresponding second side wall surfaces 23 through the connecting piece 231, the inner cavity object 50 can be mounted and fixed on the second side wall surfaces 23, so as to fix the relative position of the inner cavity object 50 in the inner cavity 20.

In one embodiment, the connection member 231 includes two connection protrusions 2311 spaced apart from each other, as shown in fig. 17. The two connection protrusions 2311 are spaced apart in a direction opposite to the first end wall 24 and the second end wall 25 of the inner cavity 20. The two connecting protruding strips 2311 are used for clamping the end portion of the inner cavity placement object 50, which is close to the second side wall surface 23, so as to mount and fix the inner cavity placement object 50 on the second side wall surface 23.

Further, referring to fig. 18 and 19, two connection protruding strips 2311 extend along the opposite direction of the access opening 21 and the first side wall 22 of the inner cavity 20, and two second side wall 23 opposite to the inner cavity 20 are respectively provided with two corresponding sets of connection members 231 for mounting and fixing the same inner cavity-mounted object 50. After the two ends of the inner cavity object 50 are aligned with the gaps between the two connection convex strips 2311 of the corresponding connection piece 231, the user can push the inner cavity object 50 along the extending direction of the connection convex strips 2311, so that the two opposite ends of the inner cavity object 50 are clamped between the two corresponding connection convex strips 2311, and the fixing of the relative position of the inner cavity object 50 in the inner cavity 20 is completed.

Of course, since the number of the inner cavity articles 50 in the inner cavity 20 is plural, multiple groups 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 articles 50, as shown in fig. 17.

In other embodiments of the present application, the connecting member 231 may include only one connecting protrusion 2311, and the inner cavity member 50 may be mounted and fixed on the second side wall surface 23 by placing the end of the inner cavity member 50 near the second side wall surface 23 above the connecting protrusion 2311 and supporting the inner cavity member 50 by the connecting protrusion 2311, which is not limited herein.

Please continue to refer to fig. 17-19. In an embodiment, in order to achieve the effect of the backflow of the cold air in the side of the second side wall surface 23 of the inner cavity 20, the connection between the second side wall surface 23 and the inner cavity object 50 needs to be provided with a side wall ventilation structure 70, so as to achieve the ventilation effect of the connection between the second side wall surface 23 and the inner cavity object 50.

Considering that the connection between the second sidewall 23 and the inner cavity object 50 needs to be provided with the sidewall ventilation structure 70 and the connection member 231, the design of the connection between the second sidewall 23 and the inner cavity object 50 and the sidewall ventilation structure 70 and the connection member 231 in the embodiment of the present application will be described below.

Please continue to refer to fig. 17 and 18. In one embodiment, the second side wall surface 23 is provided with air return guiding grooves 71 and air return guiding protrusions 72 alternately arranged one by one along the opposite direction of the object access opening 21 and the first side wall surface 22. The return air guiding groove 71 is used for realizing the ventilation effect of the connection between the second side wall surface 23 and the inner cavity object 50, and the connecting piece 231 is required to be disposed on the return air guiding protrusion 72, so that the design of the side wall ventilation structure 70 and the connecting piece 231 is compatible with the connection between the second side wall surface 23 and the inner cavity object 50.

Further, the surface of each return air guiding protrusion 72 facing the inner cavity object 50 is provided with a connecting piece 231 respectively, so as to ensure that the inner cavity object 50 is reliably installed and fixed on the second side wall surface 23, which is beneficial to improving the overall reliability of the refrigeration equipment.

The object-placing ventilation structure and the side wall ventilation structure are matched to realize multipath cold air backflow

Referring to fig. 17 to 20, fig. 20 is a partial schematic view showing a sectional structure of the refrigeration apparatus C-C shown in fig. 19.

In one embodiment, the inner cavity placement object 50 (including the first inner cavity placement object and the second inner cavity placement object described in the above embodiments) is provided with a plurality of placement object ventilation structures 60, and the connection between the second side wall surface 23 of the inner cavity 20 and the inner cavity placement object 50 is provided with a plurality of side wall ventilation structures 70. The cool air may be returned through the object-placing ventilation structure 60 and the sidewall ventilation structure 70. That is, on the basis that the cold air is returned through the gaps between the respective inner cavity placement articles 50 and the door body 30, a return path of the cold air is further increased, the circulating refrigeration of the cold air by multi-path return is realized, the diffusion range of the cold air is further advantageously increased, the coverage area of the cold air is wider, and the improvement of the refrigeration efficiency and the improvement of the refrigeration effect are further facilitated.

In an embodiment, the return air guiding grooves 71 and the return air guiding protrusions 72 are alternately arranged along the opposite direction of the storage opening 21 and the first side wall 22, and the first side edge 501 and/or the second side edge 502 of the inner cavity object 50 are concavely formed with the object ventilating structure 60, and the object ventilating structure 60 is a groove structure, as shown in fig. 18. Also, fig. 18 shows a case where both the first side edge 501 and the second side edge 502 are provided with the concave article-placement ventilation structure 60.

Specifically, the inner cavity article 50 is recessed to form an article ventilation structure 60 in the form of a recess at a location corresponding to the return air guide slot 71 in the second side wall surface 23. Further, the object ventilation structure 60 may be abutted with the return air guiding groove 71 to form a channel for the return of the cold air, which is beneficial to increasing the maximum return amount of the cold air at the position of the second side wall surface 23 of the inner cavity 20, as shown in fig. 18.

Please continue to refer to fig. 19 and 20. In an alternative embodiment, the connection member 231 is in the form of two connection protrusions 2311 spaced apart 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 cavity to house the article 50. Specifically, the first vent 73 is provided at a portion of the inner cavity body 50 that is sandwiched between the two connection protrusions 2311. The second ventilation holes 74 are provided in the connection protruding strip 2311. Specifically, the two connection protruding strips 2311 of the connection piece 231 are respectively provided with a second ventilation hole 74, and the second ventilation holes 74 on the two connection protruding strips 2311 are correspondingly arranged, so that after the inner cavity object 50 is installed and fixed on the connection piece 231, the second ventilation holes 74 on the two connection protruding strips 2311 are communicated to the first ventilation holes 73 on the inner cavity object 50, the first ventilation holes 73 and the second ventilation holes 74 form a return channel of cold air at the position where the inner cavity object 50 is connected with the second side wall surface 23, and the installation and fixation of the inner cavity object 50 on the second side wall surface 23 are realized while the position of the second side wall surface 23 of the inner cavity 20 is matched with the cold air return.

In the above embodiment, when the connector 231 includes only one connection protrusion 2311, the connection protrusion 2311 included in the connector 231 may be provided with the second ventilation hole 74 communicating with the first ventilation hole 73, so that the first ventilation hole 73 and the second ventilation hole 74 can cooperate to achieve the back flow of the cooling air at the position of the second side wall surface 23 of the inner cavity 20, which is not limited herein.

Further, the inner cavity placement member 50 is further provided with a third ventilation hole 63, the third ventilation hole 63 is provided in other areas of the inner cavity placement member 50 than the area thereof sandwiched between the two connection protrusions 2311, and the third ventilation hole 63 is provided near the first ventilation hole 73. That is, the third ventilation hole 63 is provided at a side of the first ventilation hole 73 facing away from the second side wall surface 23, as shown in fig. 19 and 20. In this way, the maximum cold air recirculation amount of the inner cavity 20 on the second side wall surface 23 side can be increased, which is beneficial to improving the recirculation efficiency of the cold air, and further beneficial to improving the refrigeration efficiency and improving the refrigeration effect.

Air supply diversion trench

Referring to fig. 21, fig. 21 is a schematic diagram showing a third embodiment of a front view structure of the refrigeration apparatus shown in fig. 1.

In one embodiment, the cool air output by the cooling device 40 is supplied along the first side wall 22 of the inner cavity 20. In order to make the first side wall surface 22 have a good air flow guiding effect, the first side wall surface 22 of the present embodiment is provided with a flow guiding groove structure extending along the opposite direction of the first end wall surface 24 and the second end wall surface 25, that is, the air flow guiding groove 81, where the air flow guiding groove 81 is communicated to the refrigeration device 40, and the cool air can flow along the air flow guiding groove 81 to the second end wall surface 25, so as to be beneficial to improving the air flow guiding effect of the first side wall surface 22.

Specifically, the first side wall surface 22 of the inner cavity 20 may be recessed away from the inner cavity object 50 to form the air supply guiding slot 81; or, a rib (hereinafter referred to as an air supply guiding protrusion 82) is disposed on the first side wall 22 of the inner cavity 20, the rib protrudes toward the inner portion of the inner cavity 20, and an air supply guiding groove 81 is formed between adjacent ribs.

The number of the air flow guiding grooves 81 is preferably plural, and the plurality of air flow guiding 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 flow guiding protrusions 82 are relatively protruded between the adjacent air flow guiding grooves 81. The air flow guide grooves 81 and the air flow guide protrusions 82 are shown to be alternately arranged one by one in the opposite direction of the two second side wall surfaces 23 of the inner cavity 20.

It should be noted that, in this embodiment, the air guiding groove 81 is preferably formed between adjacent air guiding protrusions 82 by providing the air guiding protrusions 82 protruding toward the inner portion of the inner cavity 20 with respect to the first side wall surface 22 on the first side wall surface 22 of the inner cavity 20. In this way, the cold air output to the first side wall 22 by the refrigeration device 40 still depends on the first side wall 22 to flow based on the coanda effect, and flows along the air guiding slot 81 at the same time, so that the problem that the air guiding slot 81 formed by the concave manner of the first side wall 22 requires the cold air to sink into the air guiding slot 81 to receive the guiding of the air guiding slot 81 is avoided, which is beneficial to ensuring the realization of the guiding function of the air guiding slot 81 and improving the guiding effect of the cold air.

The air guiding groove 81 and the air guiding protrusion 82 on the first side wall 22 may abut against the edge of the first inner cavity object 511 near the first side wall 22, so as to form a gap for the cool air to pass through between the first inner cavity object 511 and the first side wall 22. Of course, the air guiding groove 81 and the air guiding protrusion 82 on the first side wall 22 may be spaced from the edge of the first inner cavity object 511 near the first side wall 22, so as to form a gap for passing the cool air between the first inner cavity object 511 and the first side wall 22.

Referring to fig. 22, fig. 22 is a schematic structural diagram of a first embodiment of an air supply guiding slot of the present application.

In one embodiment, the cross-sectional area of the air flow channel 81 decreases gradually in a direction from the first end wall surface 24 to the second end wall surface 25. This means that the larger cross-sectional area of the portion of the air flow channel 81 relatively close to the first end wall surface 24 is advantageous in ensuring that as much cold air as possible enters the air flow channel 81 and flows along the air flow channel 81, i.e. that a sufficient cold air amount is fed.

Referring to fig. 23, fig. 23 is a schematic structural diagram of a second embodiment of an air supply guiding slot of the present application.

In one embodiment, the cross-sectional area of the air flow channel 81 increases gradually 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 flow guide groove 81 relatively close to the first end wall surface 24 is small. When the amount of cool air input is constant, the flow rate of cool air in the portion of the air guide groove 81 relatively close to the first end wall surface 24 is high. Based on the coanda effect, the cold air of the portion of the air guiding groove 81 relatively close to the first end wall surface 24 is attached to the first side wall surface 22 with a strong capability, so that the cold air can be ensured to attach to the first side wall surface 22 and flow under the guidance of the air guiding groove 81, which is further beneficial to improving the air guiding effect of the air guiding groove 81.

Please continue to refer to fig. 21. In one embodiment, the distance between the end of each air guiding protrusion 82 on the first side wall surface 22 near the first end wall surface 24 and the first end wall surface 24 gradually decreases from the middle to the direction near each second side wall surface 23. This means that the closer to the second side wall surface 23 the air flow guiding protrusion 82 is to the end of the first side wall surface 24 to the first side wall surface 24, the smaller the distance, and the further from the second side wall surface 23 the air flow guiding protrusion 82 is to the end of the first side wall surface 24 to the first side wall surface 24, the larger the distance.

Through the above manner, the air supply guiding protrusions 82 relatively close to the second side wall surface 23 can guide cold air to enter the air supply guiding grooves 81, so that as much cold air as possible enters the air supply guiding grooves 81 and is supplied through the air supply guiding grooves 81, and then the cold air is conveyed to the storage areas of the articles 50 in the inner cavities, so as to refrigerate the stored articles, namely, the air supply guiding grooves 81 have good air flow guiding effect.

Referring to fig. 21 and 24, fig. 24 is a schematic view showing a D-D sectional structure of the refrigeration apparatus shown in fig. 21.

In an embodiment, in a case where the cooling device 40 is disposed outside the inner cavity 20 (which will be described in detail later), the inner cavity 20 has the air inlet 28 and the air return 29, and the cooling device 40 inputs cool air into the inner cavity 20 through the air inlet 28 and then returns to the cooling device 40 through the air return 29, thereby realizing cool air circulation.

Since the cooling device 40 has a limited outlet size for outputting cool air, there is a problem that the amount of cool air introduced into the air guide groove 81 relatively far from the air inlet 28 is insufficient. In view of this, in the present embodiment, the number of the air inlets 28 on the inner cavity 20 is preferably plural, the plural air inlets 28 are sequentially spaced along the opposite direction of the two second side wall surfaces 23 of the inner cavity 20, the plural air inlets 28 are communicated with the plural air supply guiding slots 81 on the first side wall surface 22, and each air inlet 28 is respectively communicated with the refrigerating device 40 through a corresponding air duct, so as to respectively convey the cool air outputted from the refrigerating device 40 to each air inlet 28, and then the respective air inlets 28 respectively convey the cool air to the plural air supply guiding slots 81 on the first side wall surface 22.

In this way, the plurality of air inlets 28 of the inner cavity 20 are sequentially spaced along the opposite directions of the two second side wall surfaces 23 of the inner cavity 20, and the respective air inlets 28 respectively supply the cool air to the plurality of air supply channels 81 on the first side wall surface 22, so that the cool air amount inputted by the air supply channels 81 can be kept relatively uniform.

Air supply guiding groove, air supply guiding bulge, ventilation groove and wind shielding bulge

Referring to fig. 25 to 27, fig. 25 is a schematic view of an eighth embodiment of a B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, fig. 26 is a schematic view of a ninth embodiment of a B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1, and fig. 27 is a schematic view of a tenth embodiment of a B-B direction cross-sectional structure of the refrigeration apparatus shown in fig. 1.

In one embodiment, the edge of the first inner cavity placement object 511 near the first side wall surface 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 wall surfaces 23 of the inner cavity 20. The first side wall surface 22 is provided with air supply diversion trenches 81 and air supply diversion protrusions 82 which are alternately arranged one by one along the opposite direction of the two second side wall surfaces 23 of the inner cavity 20. The ventilation groove 54 and the wind shielding protrusion 55 on the first inner cavity object 511 are disposed opposite to the air supply guiding groove 81 and the air supply guiding protrusion 82 on the first side wall 22, so as to form a passage for passing cool air between the first inner cavity object 511 and the first side wall 22.

Please continue to refer to fig. 25. In one embodiment, the ventilation groove 54 on the first interior cavity object 511 is disposed opposite the air flow guiding groove 81 on the first side wall 22.

Through the above mode, the design of the ventilation groove 54 and the wind shielding protrusion 55 on the first inner cavity object 511 plays a role in ventilation and reduces the risk that objects fall from a gap between the first inner cavity object 511 and the first side wall surface 22, and the ventilation groove 54 and the air supply diversion trench 81 are arranged oppositely, so that the area of a ventilation area at the position of the air supply diversion trench 81 is increased, the first inner cavity object 511 and the first side wall surface 22 are guaranteed to pass through enough cold air, and the refrigerating effect of the objects stored in the inner cavity object 50 is guaranteed.

In the present embodiment, the wind shielding protrusion 55 is disposed opposite to the air supply guide protrusion 82. Further, the ventilation groove 54 may be abutted with the air supply guiding groove 81, and the wind shielding protrusion 55 abuts against the air supply guiding protrusion 82, so as to prevent the wind shielding protrusion 55 from being embedded in the air supply guiding groove 81 and prevent 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 object 511 and the first side wall 22 has a sufficient area, ensure that a sufficient amount of cold air passes between the first inner cavity object 511 and the first side wall 22, and be beneficial to ensuring a refrigerating effect of the objects stored in each inner cavity object 50.

Of course, in other embodiments of the present application, the wind shielding protrusion 55 on the first inner cavity object 511 may be disposed at a distance from the air guiding slot 81 and the air guiding protrusion 82, that is, the first inner cavity object 511 is disposed at a distance from the first side wall 22, which is not limited herein.

Please continue to refer to fig. 26. In an alternative embodiment, the ventilation recess 54 on the first interior cavity placement piece 511 is disposed opposite the air supply guide projection 82 on the first sidewall 22. Further, the ventilation groove 54 interfaces with the supply air guide projection 82. In other embodiments of the present application, the ventilation groove 54 may be spaced apart from the air guiding protrusion 82.

Through the above mode, the design of the ventilation groove 54 and the wind shielding protrusion 55 on the first inner cavity object 511 plays a role in ventilation and reduces the risk of dropping the object from the gap between the first inner cavity object 511 and the first side wall 22, and the ventilation groove 54 is abutted against the design of the air supply guiding protrusion 82, so that the ventilation function of the position where the air supply guiding protrusion 82 is located is realized, that is, on the basis that the air supply guiding groove 81 and the air supply guiding protrusion 82 are designed on the first side wall 22, the ventilation position between the first inner cavity object 511 and the first side wall 22 is increased, and further, the cooling effect of passing a sufficient amount of cool air between the first inner cavity object 511 and the first side wall 22 is guaranteed, so that the object stored in each inner cavity object is guaranteed.

Please continue to refer to fig. 27. In one embodiment, the ventilation groove 54 and the wind shielding protrusion 55 on the first inner cavity object 511 are in concave-convex engagement with the air guiding groove 81 and the air guiding protrusion 82 on the first side wall 22. Specifically, the wind shielding protrusion 55 on the first inner cavity object 511 is embedded in the air guiding groove 81 on the first side wall 22, and the air guiding protrusion 82 on the first side wall 22 is embedded in the ventilation groove 54 on the first inner cavity object 511.

In this way, the present embodiment allows the area of the ventilation area between the first inner cavity object 511 and the first side wall 22 to be adjusted by the way that the ventilation groove 54 and the wind shielding protrusion 55 on the first inner cavity object 511 are in concave-convex engagement with the air supply guiding groove 81 and the air supply guiding protrusion 82 on the first side wall 22, so as to be beneficial to adjusting the amount of cold air sent into the storage area of each first inner cavity object 511.

External refrigerating device

Please continue to refer to fig. 21 and 24. In one embodiment, the refrigeration device 40 may be disposed outside of the inner cavity 20. In the case where the cooling device 40 is provided outside the inner chamber 20, the inner chamber 20 also has an air inlet 28 and an air return 29. The refrigerating apparatus 40 delivers cool air to the inside of the inner cavity 20 through the air inlet 28, and the cool air circulates in the inner cavity 20 and then returns to the refrigerating apparatus 40 through the return air inlet 29.

It should be noted that, since the temperature of the refrigerating apparatus 40 is low, especially when the inner cavity 20 is used as a refrigerating chamber of the refrigerating apparatus, the refrigerating apparatus 40 is generally disposed outside the inner cavity 20, so as to avoid that the temperature inside the inner cavity 20 is too low due to the low temperature of the refrigerating apparatus 40.

Of course, in other embodiments of the present application, even though the inner cavity 20 serves as a refrigerating chamber of the refrigerating apparatus, the refrigerating apparatus 40 may be disposed inside the inner cavity 20, and only the temperature of the refrigerating apparatus 40 needs to be appropriately adjusted to avoid the temperature inside the inner cavity 20 from being too low. In addition, in the case that the refrigerating apparatus 40 is disposed in the inner chamber 20, the inner chamber 20 may be omitted from the design of the air inlet 28 and the air return 29.

For example, in the case where the cooling device 40 is disposed outside the inner cavity 20, since the cooling device 40 in the embodiment of the present application delivers the cool air to the inside of the inner cavity 20 in the direction from the first end wall surface 24 to the second end wall surface 25, it is preferable that the first end wall surface 24 is the bottom inner wall of the inner cavity 20 and the second end wall surface 25 is the top inner wall of the inner cavity 20, that is, the cooling device 40 delivers the cool air to the inside of the inner cavity 20 in the direction from the bottom inner wall of the inner cavity 20 to the top inner wall of the inner cavity 20.

Please continue to refer to fig. 24. The refrigerating apparatus shown in fig. 24 may be understood that the refrigerating device 40 is disposed in the inner cavity 20, but the refrigerating apparatus is additionally provided with a fan cover disposed on the refrigerating device 40, the fan cover is provided with an air inlet 28 and an air return 29, the refrigerating device 40 outputs cold air through the air inlet 28, and the cold air flows back to the refrigerating device 40 through the air return 29. It can be seen that the provision of the hood ensures the formation of a cool air circulation loop.
