Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to an air guide and a refrigeration device equipped with the air guide. Background Technology

[0002] As people's living standards improve, the requirements for the uniformity of cooling within refrigerator compartments are becoming increasingly stringent. Currently, the typical airflow path within a refrigerator compartment is: top rear air outlet, bottom / bottom rear return air. However, this path suffers from insufficient cooling at the front of the compartment.

[0003] To address this, some refrigerators incorporate an air duct at the top of the cooling compartment, directing the cold air from the duct behind the cooling compartment to the front of the top of the cooling compartment. However, due to limitations in mold design for the air duct structure, it is typically constructed from two components joined together, which presents challenges in achieving proper sealing between the inner and outer parts. Summary of the Invention

[0004] The purpose of this application is to provide an air guide that solves the sealing problem in the prior art by using an upper air guide and a lower air guide that are inserted vertically.

[0005] To achieve one of the aforementioned objectives, one embodiment of this application provides an air guide component, which includes an air inlet, an air outlet, and an air guide channel connecting the air inlet and the air outlet. The air guide component includes an upper air guide component and a lower air guide component that are inserted vertically. One of the air inlet and the air outlet is located in the upper air guide component, and the other is located in the lower air guide component. The upper air guide component includes an upwardly bent and extended upper flange, and the lower air guide component includes an upwardly bent and extended lower flange. One of the upper flange and the lower flange is provided with a snap-fit ​​groove, and the other is provided with a snap-fit ​​piece. The snap-fit ​​piece is inserted into the snap-fit ​​groove in the vertical direction.

[0006] In one embodiment of this application, the lower flange is provided with an upward-opening snap-fit ​​groove, and the upper flange is provided with two snap-fit ​​pieces spaced apart, wherein the snap-fit ​​piece located on the inner side is inserted into the snap-fit ​​groove, and the snap-fit ​​piece located on the outer side of the snap-fit ​​groove and blocks the opening of the snap-fit ​​groove.

[0007] In one embodiment of this application, a first buckle is provided at an interval between the upper and lower flanges, and a corresponding snap-fit ​​hole is provided on the other flange, with the first buckle and the snap-fit ​​hole fastening each other.

[0008] In one embodiment of this application, the air guide further includes an air distribution column disposed in the air guide channel, one end of which is connected to one of the upper air guide and the lower air guide, and the other end abuts against the other of the upper air guide and the lower air guide.

[0009] In one embodiment of this application, the air inlet is offset from the central axis of the air guide channel, and the air distribution column includes at least a first air distribution column disposed near the air inlet. The first air distribution column is offset from the central axis of the air inlet, and the offset direction is consistent with the direction of the air inlet offset from the central axis of the air guide channel. The central axis of the air guide channel and the central axis of the air inlet are both the central axis of the air flow direction within the air guide channel.

[0010] In one embodiment of this application, the air distribution column further includes a second air distribution column, which is arranged in multiple rows along the air inlet direction, and any row is arranged in multiple rows along the vertical air inlet direction.

[0011] In one embodiment of this application, any second wind distribution column is staggered with the second wind distribution columns in the adjacent row.

[0012] One embodiment of this application also provides a refrigeration device, including a housing, a first inner liner disposed within the housing, and a guide air component communicating with the first inner liner, wherein the guide air component is as described above.

[0013] In one embodiment of this application, the refrigeration device further includes a second inner liner disposed above the first inner liner, and the air guide connects the first inner liner and the second inner liner; The air guide also includes a main body fixed to the top of the first inner liner, a first air duct connected to the front side of the main body, and a second air duct connected to the rear side of the main body. The front side of the first air duct extends downward at an angle, and the front side of the second air duct is connected to the main body at an angle.

[0014] In one embodiment of this application, the refrigeration equipment further includes a cabinet opening component, which has a first wall extending vertically and having a frame opening, and a second wall extending rearward from the edge of the frame opening to connect with a first inner liner. The second wall has a first connecting portion located at the rear end to connect with the front end of the first inner liner, and an air vent portion disposed between the first connecting portion and the first wall. The top of the air vent portion has a first ventilation hole extending vertically. The first air duct is connected to the first ventilation hole on the air vent portion.

[0015] One or more technical solutions provided in this application have at least the following technical effects or advantages: In the air guide provided in this application, the upper air guide and the lower air guide are fastened together. In addition, by setting a first buckle and a snap-fit ​​groove, the upper air guide and the lower air guide are inserted and connected vertically, so that in the horizontal direction, the upper air guide and the lower air guide partially overlap, preventing the cold air flowing through the air guide from leaking out of the gap between the two.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] The terms used in this document, such as “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicating spatial relative positions, are used for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative positions” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0035] For example, if the device in the figure is flipped, a unit described as being "below" or "under" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first wireless communication device may be referred to as a second wireless communication device, and similarly, a second wireless communication device may be referred to as a first wireless communication device, without departing from the scope of protection of this application.

[0038] This application provides an air guide 5, such as... Figure 1 As shown in Figure 5, an air inlet 5111, an air outlet 5211, and an air guide channel 531 connecting the air inlet 5111 and the air outlet 5211 are provided. The air guide 5 includes an upper air guide 51 and a lower air guide 52 that are inserted vertically. One of the air inlet 5111 and the air outlet 5211 is provided in the upper air guide 51, and the other is provided in the lower air guide 52. The upper air guide 51 includes an upper flange 512 with its edge bent downwards, and the lower air guide 52 includes a lower flange 522 with its edge bent upwards. One of the upper flange 512 and the lower flange 522 is provided with a snap-fit ​​groove 5221, and the other is provided with a snap-fit ​​piece 5121. The snap-fit ​​piece 5121 is inserted into the snap-fit ​​groove 5221 in the vertical direction.

[0039] After the cold air enters the air guide channel 531 through the air inlet 5111, it flows out of the air guide component 5 through the air outlet 5211, thus completing the air guiding function of the air guide component 5.

[0040] The upper flange 512 and the lower flange 522 are interlocked to connect the upper air guide 51 and the lower air guide 52 vertically, and the interlocking method has an overlapping part, which can avoid the formation of gaps at the connection between the upper air guide 51 and the lower air guide 52, which would cause cold leakage. On the other hand, after the upper flange 512 and the lower flange 522 are interlocked vertically, they form the side wall of the air guide channel 531.

[0041] In some embodiments of this application, the lower flange 522 is provided with an upward-opening snap-fit ​​groove 5221, and the upper flange 512 is provided with two snap-fit ​​pieces 5121 spaced apart from each other. The snap-fit ​​piece 5121 located on the inner side is inserted into the snap-fit ​​groove 5221, and the snap-fit ​​piece 5121 located on the outer side is located outside the snap-fit ​​groove 5221 and blocks the opening of the snap-fit ​​groove 5221.

[0042] A snap-fit ​​groove 5221 is located on the lower flange 522, and a snap-fit ​​piece 5121 is located on the upper flange 512. The upper flange 512 is inserted into the snap-fit ​​groove 5221 from top to bottom. The snap-fit ​​groove 5221 opens upwards, and another snap-fit ​​piece 5121 is connected to the outside of the snap-fit ​​piece 5121. The connection position of the two snap-fit ​​pieces 5121 covers the opening of the snap-fit ​​groove 5221. Alternatively, it can be understood as two C-shaped grooves interlocking with each other, forming a double-layer protective structure with better sealing.

[0043] Of course, it can also be considered that the snap-fit ​​slot 5221 is set on the upper flange 512 and the snap-fit ​​piece 5121 is set on the lower flange 522, that is, the insertion method shown in the figure is exchanged in the inner and outer directions (the air guide channel 531 is the inner direction).

[0044] In some embodiments of this application, a first buckle 5222 is provided at an interval between the upper flange 512 and the lower flange 522, and a corresponding snap hole 5122 is provided in the other flange, with the first buckle 5222 and the snap hole 5122 fastening each other.

[0045] like Figure 1 In this configuration, a first snap fastener 5222 is located on the lower flange 522, and a snap-fit ​​hole 5122 is located on the upper flange 512. Specifically, the first snap fastener 5222 is located on the outer side of the lower flange 522, and the snap-fit ​​hole 5122 is located on the outer snap-fit ​​piece 5121 in the upper flange 512. When the upper flange 512 and the lower flange 522 are inserted vertically, the first snap fastener 5222 snaps into the snap-fit ​​hole 5122, thereby limiting the vertical movement of the upper air guide 51 and the lower air baffle 8 and preventing them from separating vertically.

[0046] In some embodiments of this application, the air guide 5 further includes an air distribution column 54 disposed in the air guide channel 531, one end of which is connected to one of the upper air guide 51 and the lower air guide 52, and the other end abuts against the other of the upper air guide 51 and the lower air guide 52.

[0047] like Figure 3 In the middle, the air distribution column 54 is connected to the upper air guide 51 and abuts against the lower air guide 52. The air distribution column 54 is set in the air guide channel 531, which can support the upper air guide 51 and the lower air guide 52 while distributing air, and prevent the weaker supporting part in the middle of the flat air guide from collapsing.

[0048] In some embodiments of this application, the air inlet 5111 is offset from the central axis of the air guide channel 531, and the air distribution column 54 includes at least a first air distribution column 541 disposed near the air inlet 5111. The first air distribution column 541 is offset from the central axis of the air inlet 5111, and the offset direction is consistent with the direction of the air inlet 5111 offset from the central axis of the air guide channel 531. The central axis of the air guide channel 531 and the central axis of the air inlet 5111 are both the central axis of the air flow direction within the air guide channel 531.

[0049] It should be noted that the direction of airflow within the air guide channel 531 involved in the central axis does not specifically refer to the direction of a single stream of air within the air guide channel 531 (there can be many different directions), but rather refers to the general direction from the air inlet 5111 to the air outlet 5211. For example, when the air guide component 5 is installed in the refrigeration equipment to guide the cold air from the rear to the front, the direction of the central axis is the front-to-back direction.

[0050] The air inlet 5111 is set off-center relative to the air guide 5, and the first air distribution column 541 near the air inlet 5111 is set off-center relative to the air inlet 5111, with the two being off-center in the same direction. As a result, most of the cold air entering the air guide 5 from the air inlet 5111 flows to the opposite side of the eccentricity (i.e., the side of the air guide channel 531 where the air inlet 5111 is not located) under the air distribution of the first air distribution column 541, thus avoiding uneven distribution of cold air, with less cold air on the opposite side and more cold air on the eccentric side.

[0051] In some embodiments of this application, the air distribution column 54 further includes a second air distribution column 542. Multiple rows of second air distribution columns 542 are spaced apart along the air inlet direction, and multiple columns are spaced apart along the vertical air inlet direction in any given row. That is, except for the first air distribution column 541 near the air inlet 5111, all other air distribution columns 54 are second air distribution columns 542. It should be noted that this air inlet direction is the direction in which cold air enters the air guide channel 531 (horizontal direction), not the direction in which cold air enters the second air duct 511 described below from the air inlet 5111 (vertical direction).

[0052] In some embodiments of this application, any second air distribution column 542 is staggered with the second air distribution column 542 in the adjacent row to guide the cold air evenly, so that the cold air blown out from the air outlet 5211 is uniform.

[0053] In some embodiments of this application, the shapes of the first wind distribution column 541 and the second wind distribution column 542 are as follows: Figure 5a and 5b The teardrop shape has a pointed end facing the air inlet 5111 and a blunt end facing the air outlet 5211, so that the cold air entering the air guide channel 531 is distributed by the pointed end.

[0054] The first air distribution column 541 and the second air distribution column 542 are set in the direction of air intake ( Figure 5a (In the vertically downward direction), the blunter end of the teardrop shape can also be tilted towards the side where the air inlet 5111 is not installed ( Figure 5b (The middle is skewed to the right).

[0055] This application also provides a refrigeration device, including a housing 1, a first inner liner 11 disposed within the housing 1, and the aforementioned air guide 5 communicating with the first inner liner 11. The aforementioned air guide 5 guides cold air outside the first inner liner 11 into the first inner liner 11. Of course, the air guide 5 can also be used as a return air channel for the first inner liner 11. In this application, the air guide 5 is used as an example for supplying air.

[0056] In some embodiments of this application, the refrigeration device further includes a second inner liner 12 disposed above the first inner liner 11, and the air guide 5 connects the first inner liner 11 and the second inner liner 12.

[0057] The air guide 5 also includes a main body 53 fixed to the top of the first inner liner 11, a first air duct 521 connected to the front side of the main body 53, and a second air duct 511 connected to the rear side of the main body 53. The front side of the first air duct 521 extends downward at an angle, and the front side of the second air duct 511 is connected to the main body 53 at an angle.

[0058] The main body 53 is roughly parallel to the side of the first inner liner 11. The first air duct 521 bends downward from the front of the main body 53 and connects to the interior space of the first inner liner 11 through the air outlet 5211. The second air duct 511 bends upward from the rear of the main body 53 and connects to the interior of the second inner liner 12 through the air inlet 5111. The cold air in the second inner liner 12 is transferred from back to front to the interior of the first inner liner 11 through the air guide 5. Alternatively, the cold air in the first inner liner 11 can be transferred from front to back to the interior of the second inner liner 12 through the air guide 5.

[0059] In some embodiments of this application, such as Figure 8 In the middle, screw posts 113 are arranged at intervals along the edge of the air guide 5 at the top of the first inner liner 11. Figure 5a The upper flange 512 extends outward from the screw post 113 and is provided with a first fixing part 5123. The first fixing part 5123 has a mounting hole. The fastener passes through the mounting hole and is fixed to the screw post 113, so that the air guide 5 is fixed to the first inner liner 11.

[0060] The air guide 5 is fixed to the top of the first inner liner 11 by screws. The first fixing part 5123 is set on the upper flange 512, so that when the screw is tightened, the upper flange 512 applies pressure downward to the lower flange 522, making the upper air guide 51 and the lower air guide 52 more tightly inserted.

[0061] In some embodiments of this application, such as Figures 9-12 The refrigeration equipment also includes a cabinet opening component 7, which has a first wall 71 extending vertically and having a frame opening 711, a second wall 72 extending rearward from the edge of the frame opening 711 to connect with the first inner liner 11, the second wall 72 having a first connecting portion 722 located at the rear end to connect with the front end of the first inner liner 11, and an air vent portion 721 disposed between the first connecting portion 722 and the first wall 71, the top of the air vent portion 721 having a first ventilation hole 7211 penetrating vertically; and a first air duct 521 connecting with the first ventilation hole 7211 on the air vent portion 721.

[0062] A cabinet opening component 7 is connected to the front end of the first inner liner 11. By opening a first ventilation hole 7211 on the cabinet opening component 7, the air guide component 5 is connected to the first inner liner 11, thus avoiding the need to process through holes on the first inner liner 11, so that the foaming material overflows into the first inner liner 11 when the box 1 is foaming.

[0063] The first wall 71 is a vertically arranged wall, and the second wall 72 is a ring-shaped surface. The first connecting part 722 has a C-shaped cross-section with the opening facing backward. The front end of the first inner liner 11 is inserted into the C-shaped first connecting part 722, so that the cabinet opening piece 7 is connected to the front end of the first inner liner 11.

[0064] Specifically, the front end of the first inner liner 11 is provided with a snap-fit ​​part 117. The cross-section of the snap-fit ​​part 117 is a C-shaped structure with the opening facing forward. The bottom of the C-shaped snap-fit ​​part 117 is inserted into the first connecting part 722, and the top is provided with a slot 1171. The top of the first connecting part 722 is provided with a second buckle 7221. When the cabinet opening part 7 and the first inner liner 11 are inserted front to back, the second buckle 7221 and the slot 1171 are snapped together.

[0065] The front end of the first inner liner 11 is also set to have a C-shaped cross-section, so that when the front end of the first inner liner 11 is inserted into the C-shaped first connecting part 722, the second buckle 7221 on the first connecting part 722 can be engaged in the slot 1171 at the top of the engaging part 117, thus preventing the cabinet opening part 7 and the first inner liner 11 from separating in the front-back direction.

[0066] Regarding the connection structure between cabinet opening component 7 and air guide component 5, combined with Figure 4 , 12A third buckle 5212 is provided on the outer side of the rear wall of the first air duct 521 located on the front side. The first air duct 521 extends into the first ventilation hole 7211, and the third buckle 5212 is engaged with the air outlet 721 located at the lower rear side of the first ventilation hole 7211.

[0067] By inserting the first air duct 521 into the first ventilation hole 7211, it is ensured that the cold air inside the air guide 5 completely passes through the second wall 72 of the cabinet opening 7, preventing cold air leakage from the connection between the air guide 5 and the cabinet opening 7. The third clip 5212 is engaged with the air outlet 721 to limit the upward movement of the air guide 5.

[0068] The air vent 721 includes a plurality of first connecting ribs 7212 spaced apart along the width direction of the housing 1, the first connecting ribs 7212 dividing the first ventilation hole 7211 into a plurality of small holes.

[0069] The first air duct 521 is provided with a plurality of second connecting ribs 5213 spaced apart along the width direction of the housing 1. The second connecting ribs 5213 divide the air duct into a plurality of small channels, and the second connecting ribs 5213 overlap the first connecting ribs 7212.

[0070] The first air duct 521 and the first ventilation hole 7211 are divided into small channels and small holes, so that the cold air entering the first air guide cavity 613 from the air guide 5 is uniform. The first connecting rib 7212 supports the second connecting rib 5213, provides support for the second connecting rib 5213, and together with the third buckle 5212 and the air outlet 721, it plays a limiting role in the vertical direction.

[0071] In some embodiments of this application, the air guide 5 further includes a sealing part 55 disposed on the front side of the first air duct 521. The sealing part 55 is supported on the air outlet 721 located on the front side of the first ventilation hole 7211, and the sealing part 55 abuts against the first wall 71 through a sealing member 56.

[0072] The air vent 721 also provides a certain support for the sealing part 55 (the front end of the air guide 5). A sealing element 56 is provided between the sealing part 55 and the first wall 71. The sealing element 56 is made of soft or elastic material and is squeezed and deformed between the sealing part 55 and the first wall 71, so that the front end of the air guide 5 can be sealed with the first wall 71 to prevent the foam material from overflowing.

[0073] In some embodiments of this application, the first wall 71 includes an abutment portion 712, which is located at the top of the frame opening 711. The abutment portion 712 is inclined from front to back, and the sealing portion 55 abuts against the abutment portion 712.

[0074] In the first wall 71, the part that abuts against the sealing barrier is the abutting part 712. The abutting part 712 extends backward from front to back in the vertical direction, so that the abutting part 712 is inclined. When the air guide 5 is fixed to the top of the first inner liner 11 from top to bottom, the sealing part 55 at the front end of the air guide 5 can give the abutting part 712 a downward force, so that the sealing part 55 and the abutting part 712 are pressed together.

[0075] In one embodiment of this application, as Figure 13 In the refrigeration equipment, there is also a drawer assembly 6, which includes a drawer body 61 that moves in the front-to-back direction within a first inner liner 11.

[0076] The interior of the drawer body 61 is divided by a partition plate 611 to form a first air guide cavity 613 on the front side and a storage cavity 612 on the rear side. A second air guide cavity 614 is formed between the bottom of the drawer body 61 and the bottom of the first inner liner 11. A third air guide cavity 615 is formed between the rear side of the drawer body 61 and the rear side of the first inner liner 11. The upper side of the first air guide cavity 613 is connected to the air outlet 5211, and the lower side is connected to the second air guide cavity 614. The second air guide cavity 614 and the third air guide cavity 615 are connected.

[0077] The air guide 5 transmits the cold air from the second inner liner 12 to the first inner liner 11, and then passes through the first air guide cavity 613, the second air guide cavity 614 and the third air guide cavity 615 outside the storage cavity 612 in sequence. That is, an air passage is formed outside the storage cavity 612 to prevent the cold air from flowing through the food in the storage cavity 612 and taking away the moisture of the food. At the same time, it can also prevent the bacteria from the second inner liner 12 in the cold air from coming into contact with the food.

[0078] In some embodiments of this application, a return air vent 116 is provided at the top of the first inner liner 11, and the return air vent 116 extends downward to form a return air duct 1161. The bottom end of the return air duct 1161 is not higher than the top end of the rear side of the drawer body 61. The return air vent 116 and the second air duct 511 are spaced apart in the width direction of the refrigeration equipment at the rear side of the first inner liner 11.

[0079] After cold air flows into the first inner liner 11 from the air guide 5, it flows around the storage cavity 612 along the first air guide cavity 613, the second air guide cavity 614 and the third air guide cavity 615, and then flows out from the return air port 116 at the top of the first inner liner 11, completing the circulation.

[0080] To ensure the smooth pulling of the drawer body 61, the top of the drawer body 61 cannot be flush with the top wall of the first inner liner 11, and a certain gap needs to be set. Therefore, the cold air in the third air guide cavity 615 may enter the storage cavity 612 from the gap between the top of the drawer body 61 and the top of the first inner liner 11.

[0081] The return air vent 116 is extended downwards to the bottom of the return air duct 1161, which is no higher than the top of the rear side of the drawer body 61. Cold air enters the return air duct 1161 at a lower position to achieve return air, which greatly reduces the amount of cold air entering the storage cavity 612.

[0082] In some embodiments of this application, such as Figures 13-15 The drawer body 61 is provided with second ventilation holes 6131 at the top and bottom of the first air guide cavity 613, so that the air outlet 5211, the first air guide cavity 613 and the second air guide cavity 614 are connected in sequence.

[0083] The top of the second wall 72 corresponds to the top of the first air guide cavity 613. The two are respectively provided with a first ventilation hole 7211 and a second ventilation hole 6131. ​​The front end of the air guide 5 is pressed against the second wall 72, so that the cold air in the air guide 5 flows out from the air outlet 5211 and then enters the first air guide cavity 613 through the first ventilation hole 7211 and the second ventilation hole 6131 in sequence. Then it flows into the second air guide cavity 614 from the second ventilation hole 6131 at the bottom of the first air guide cavity 613. The cold air continues to pass through the second air guide cavity 614 and the third air guide cavity 615, and flows out of the first inner liner 11 from the return air port 116 located at the top of the first inner liner 11.

[0084] In some embodiments of this application, the first air guide cavity 613 has an opening at the front, and the drawer assembly 6 also includes a partition 62 that blocks the front of the first air guide cavity 613.

[0085] The refrigeration equipment also includes a door 63 connected to the drawer assembly 6, a partition 62 spaced apart from the door 63, and the partition 62 is provided with a vent 621.

[0086] The drawer body 61 is divided into a first air guide cavity 613 and a storage cavity 612 by a partition plate 611. The first air guide cavity 613 has walls on its top, bottom and sides. For ease of processing, the front of the first air guide cavity 613 needs to be open. A baffle 62 is provided on the front of the first air guide cavity 613 to close the front opening of the first air guide cavity 613, forming a cavity with ventilation at the top and bottom.

[0087] Since the first air guide cavity 613 circulates cold air and the front side of the first air guide cavity 613 is adjacent to the door body 63, when the drawer assembly 6 is opened, hot air from the outside can easily enter the gap between the door body 63 and the partition 62, and condensation can easily form on the door body 63 after the drawer assembly 6 is closed.

[0088] A vent 621 is provided on the partition 62. After the drawer assembly 6 is closed, the hot air between the door 63 and the partition 62 is carried away through the vent 621, preventing the hot air from coming into contact with the cold air and causing condensation on the door 63.

[0089] Of course, the top or bottom of the first air guide cavity 613 can also be opened, and the air vent 621 is set on the wall on the front side of the first air guide cavity 613.

[0090] In some embodiments of this application, a plurality of fourth buckles 616 are provided on the front side of the drawer body 61, and a fifth buckle 623 and a fixing groove 6221 are provided on the partition member 62. The plurality of fourth buckles 616 are engaged with the fifth buckle 623 or the fixing groove 6221, so that the partition member 62 is connected to the drawer body 61.

[0091] The divider 62 is connected to the drawer body 61 by a snap-fit, which is convenient and has a simple structure.

[0092] In some embodiments of this application, the size of the partition 62 matches the front opening of the first air guide cavity 613, and the partition 62 is disposed inside the front opening of the first air guide cavity 613.

[0093] The partition 62 is placed inside the first air guide cavity 613. Even if the buckle is damaged and the connection is not secure, the bottom of the first air guide cavity 613 can provide a certain support for the partition 62, preventing the partition 62 from falling off directly.

[0094] Specifically, the partition 62 extends backward from both ends along the width and length direction of the refrigeration equipment and is provided with a second connecting part 622. The second connecting part 622 is provided with a fixing groove 6221. The top of the partition 62 is also provided with a fixing groove 6221. The fifth buckle 623 is provided at the bottom of the partition 62.

[0095] The first air guide cavity 613 is provided with a fourth buckle 616 at the top, bottom and both sides. The fourth buckle 616 on both sides engages with the fixing groove 6221 on the second connecting part 622, the fourth buckle 616 at the top engages with the fixing groove 6221 at the top of the partition 62, and the fourth buckle 616 at the bottom engages with the fifth buckle 623.

[0096] In some embodiments of this application, a guide rib 624 is provided on the rear side of the partition 62. The guide rib 624 cooperates with two second connecting parts 622 at both ends to form multiple adjacent channels along the width direction of the first air guide cavity 613, so that the air outlet below the first air guide cavity 613 is uniform.

[0097] In some embodiments of this application, the cabinet opening component 7 further includes a first mounting portion 723 extending from the front end into the inner side of the top of the first inner liner 11, and the refrigeration device further includes a wind deflector 8, which includes a second mounting portion 81 connected to the first mounting portion 723 and an abutment piece 82 extending downward and forward from the second mounting portion 81. When the drawer assembly 6 is closed, the abutment piece 82 abuts against the rear side of the partition plate 611.

[0098] like Figure 12In this configuration, the first mounting part 723 is connected to the rear end of the bottom of the C-shaped first connecting part 722 and is horizontally positioned. The second mounting part 81 has a C-shaped cross-section, and the first mounting part 723 is horizontally inserted into the C-shaped second mounting part 81. Of course, the first mounting part 723 can also be inclined or vertically positioned, and its insertion direction with the second mounting part 81 will also change due to its own setting direction.

[0099] When the drawer assembly 6 is closed, the abutment piece 82 abuts against the rear side of the partition plate 611, so that the storage cavity 612 inside the drawer body 61 is separated from the first air guide cavity 613 by the abutment piece 82, preventing cold air from entering the storage cavity 612 and forming a loop from the rear side of the storage cavity 612, thus taking away the moisture of the food.

[0100] In some embodiments of this application, the first mounting part 723 is provided with a sixth buckle 7231, and the C-shaped second mounting part 81 is provided with a seventh buckle 811. When the first mounting part 723 is inserted into the second mounting part 81, it is engaged by the sixth buckle 7231 and the seventh buckle 811, thereby limiting the upper limit in the front and rear directions and preventing the windshield 8 from detaching from the first mounting part 723.

[0101] In some embodiments of this application, such as Figure 13 In the middle, a limiting rib 118 is provided on the inner side of the top of the first inner liner 11, and the rear end of the second mounting part 81 abuts against the front end of the limiting rib 118, further preventing the windproof part 8 from moving backward and separating from the first mounting part 723.

[0102] In some embodiments of this application, the first mounting portion 723 is provided with protrusions at both ends, the protrusions protruding from the first mounting portion 723 to prevent the windshield member 8 from disengaging from the first mounting portion 723 along its length direction.

[0103] In some embodiments of this application, a notch 83 is formed at the connection between the second mounting part 81 and the abutment piece 82 to reduce the connection strength between the two and the deformation strength of the abutment piece 82, so as to avoid the drawer assembly 6 being blocked by the abutment piece 82 when closed due to the excessive strength between the second mounting part 81 and the abutment piece 82, which would prevent it from being completely closed and cause cold leakage.

[0104] In some embodiments of this application, when the drawer assembly 6 is opened and closed, the distance between the front end of the abutment piece 82 in the front-back direction is 2~8mm.

[0105] When drawer assembly 6 is opened, the abutment piece 82 loses its abutting force and returns to its normal shape. At this time, the front end of the abutment piece 82 will move forward. When drawer assembly 6 is closed, the front end of the abutment piece 82 will move backward due to the abutting force of the partition plate 611.

[0106] Therefore, when the drawer assembly 6 is opened and closed, the front end of the abutment piece 82 will be displaced in the front-back direction by 2~8mm, that is, the interference of the abutment piece 82 is 2~8mm.

[0107] In some embodiments of this application, such as Figure 12 In the middle, a second fixing part 713 is recessed on the first wall 71, and the refrigeration equipment also includes a decondensation pipe disposed on the second fixing part 713 (the decondensation pipe is not shown in the figure, it is disposed on...). Figure 12 (In the recess of the second fixing part 713), the distance between the dew duct and the internal cavity of the air guide 5 in any radial direction of the dew duct is not less than 10mm.

[0108] The cabinet opening 7 is exposed to cold air on all sides and to hot air on all sides, making it prone to condensation. The first wall 71 is provided with second fixing parts 713 at the top, bottom and both ends to fix the decondensation pipe and prevent condensation from forming on the cabinet opening 7.

[0109] Because the temperature of the condensate pipe is too high, being too close to the air guide 5 will cause the temperature of the cold air inside the air guide 5 to rise, reducing the cooling efficiency of the first inner liner 11. Therefore, the minimum distance between the condensate pipe and the internal cavity of the air guide 5 should be controlled to be no less than 10mm to avoid the condensate pipe reducing the cooling capacity provided by the air guide 5.

[0110] The cross section mentioned in this application is not a horizontal section, but a vertical section along the extension length of the corresponding structure.
