Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigeration device. Background Technology

[0002] Because the front of the refrigerator's inner liner is close to the outside air, some of it is prone to condensation due to the warm outside air, which can easily form condensate at the cabinet opening. To avoid this, a decondensation pipe is installed at the cabinet opening to reduce the temperature difference between the outside air and the cabinet opening.

[0003] However, some refrigerators have an air duct at the top of the inner liner to make the cold air distribution in the cooling compartment more even. The cold air in the rear air duct, which is connected to the evaporator compartment, is transferred to the front of the inner liner through the air duct at the top of the inner liner. The high temperature of the condenser pipe at the cabinet opening will affect the amount of cold air in the air duct at the top of the inner liner, thus affecting the cooling effect of the cooling compartment.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] 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.

[0043] This application provides a refrigeration device, such as... Figures 1-5 As shown, it includes a housing 1, an inner liner assembly disposed within the housing 1, an air guide 5, and a decondensation pipe (the decondensation pipe is not shown, but is disposed within...). Figure 5 (The first fixed part is recessed).

[0044] The inner liner assembly includes a cabinet opening 7 and a first inner liner 11 connected front and rear. The cabinet opening 7 has a first wall 71 extending vertically and provided with a frame opening 711, and a second wall 72 extending rearward from the edge of the frame opening 711 to connect with the front end of the first inner liner 11. The second wall 72 is provided with a first ventilation hole 7211. The first wall 71 is recessed with a first fixing part 713, and the de-condensation pipe is fixed to the first fixing part 713.

[0045] The air guide 5 is fixed to the first inner liner 11, and the air guide 5 includes an air duct 521 that is connected to the first ventilation hole 7211. In any radial direction of the decondensation pipe, the distance between the decondensation pipe and the internal cavity of the air guide 5 is not less than 10mm.

[0046] In this embodiment, as Figure 2 In the middle, a second inner liner 12 is also provided above the first inner liner 11. The air guide 5 and the air duct 521 are respectively provided with a docking part 511. The docking part 511 docks with the bottom of the second inner liner 12 and is connected to the second inner liner 12.

[0047] In the refrigeration equipment provided in this application, a cabinet opening 7 is connected to the front end of the first inner liner 11, and a decondensation pipe is fixed on the cabinet opening 7; the first inner liner 11 is cooled by a guide air 5, and the cold air in the guide air 5 enters the first inner liner 11 through the first ventilation hole 7211 opened on the cabinet opening 7, and the distance between the decondensation pipe and the internal cavity of the guide air 5 is controlled to not exceed 10mm, so as to avoid the temperature of the decondensation pipe affecting the temperature of the cold air in the guide air 5.

[0048] In some embodiments of this application, the first ventilation hole 7211 is located at the top of the second wall 72, the air guide 5 is fixed to the top of the first inner liner 11, and the front side of the air duct 521 extends forward and then downward in a downward direction.

[0049] The air guide 5 is placed at the top of the first inner liner 11, so that cold air enters from the top of the first inner liner 11 and sinks naturally due to its higher density, which reduces the requirements for the fan speed of the refrigeration equipment.

[0050] In some embodiments of this application, the air guide 5 is fixed to the top of the first inner liner 11 by fasteners, and the second wall 72 includes an air vent 721 with a first ventilation hole 7211. The air duct 521 is pressed into the air vent 721, so that the air duct 521 is connected to the first ventilation hole 7211.

[0051] Combination Figure 15 , 10 In the first inner liner 11, first screw posts 113 are spaced apart along the edge of the air guide 5 at the top. The air guide 5 extends outward from the first screw posts 113 and is provided with a second fixing part 5123. The second fixing part 5123 has a mounting hole. Fasteners pass through the mounting hole and are fixed to the first screw posts 113, so that the air guide 5 is fixed to the first inner liner 11. At the same time, downward pressure is applied to the air guide 5, so that the air duct 521 also applies downward pressure to the air outlet 721, so that the two are pressed together and cold air is prevented from leaking.

[0052] In some embodiments of this application, the air guide 5 has a main body portion 53 fixed to the top of the first inner liner 11 and a docking portion 511 connected to the rear side of the main body portion 53. A ventilation channel connecting the ventilation pipe 521 and the docking portion 511 is formed inside the main body portion 53.

[0053] Specifically, the air guide 5 has an upper air guide 51 and a lower air guide 52 that are interlocked in the vertical direction, and an air guide channel 531 is formed between the upper air guide 51 and the lower air guide 52. The air duct 521 is formed at the front end of the lower air guide 52, and the docking part 511 is formed at the rear side of the air guide 5.

[0054] The second fixing part 5123 is provided on the upper flange 512, which enables the upper air guide 51 to apply pressure to the lower air guide 52 downward when the screw is tightened, so that the upper air guide 51 and the lower air guide 52 are more tightly inserted.

[0055] In some embodiments of this application, the upper air guide 51 has an upwardly bent edge 512 extending downwards, and the lower air guide 52 has an upwardly bent edge 522 extending upwards. One of the upper edge 512 and the lower edge 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.

[0056] 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. Since the air guide 5 is located on the outside of the first inner liner 11, that is, exposed inside the insulation layer, the interlocking method has an overlapping part, which can prevent the foam material from entering the air guide channel 531. 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.

[0057] 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.

[0058] 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 upward (away from the first inner liner 11 and towards the insulation layer). To prevent foam material from entering the snap-fit ​​groove 5221, 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 blocks the opening of the snap-fit ​​groove 5221.

[0059] Of course, it can also be considered that the snap-fit ​​groove 5221 is set on the upper flange 512 and the snap-fit ​​piece 5121 is set on the lower flange 522. In this case, the snap-fit ​​groove 5221 opens downward (towards the first inner liner 11 and away from the direction of the insulation layer), so there is no need to set two snap-fit ​​pieces 5121 for shielding.

[0060] 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.

[0061] like Figure 6In this configuration, a first latch 5222 is located on the lower flange 522, and a latching hole 5122 is located on the upper flange 512. Specifically, the first latch 5222 is located on the outer side of the lower flange 522, and the latching hole 5122 is located on the outer latching piece 5121 of the upper flange 512. When the upper flange 512 and the lower flange 522 are inserted vertically, the first latch 5222 engages with the latching hole 5122, thereby limiting the vertical movement of the upper air guide 51 and the lower air guide 52 and preventing them from separating vertically.

[0062] In some embodiments of this application, the air guide 5 is provided with a plurality of air distribution columns 54, which are disposed in the air guide channel 531, and one end of the air distribution column 54 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.

[0063] like Figure 8 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. While distributing air, it can support the upper air guide 51 and the lower air guide 52, and also prevent the weaker supporting part in the middle from collapsing due to the impact of the foam material.

[0064] In some embodiments of this application, the docking portion 511 is offset from the central axis of the main body portion 53 in the left-right direction of the refrigeration equipment, and the air distribution column 54 includes at least a first air distribution column 541 disposed near the docking portion 511. The first air distribution column 541 is offset from the central axis of the docking portion 511 in the left-right direction of the refrigeration equipment, and the offset direction is consistent with the direction of the docking portion 511 offset from the main body portion 53.

[0065] The duct 521 serves as the air outlet of the air guide 5, and has a first air vent 5211 on it; the connecting part 511 serves as the air inlet of the air guide 5, and is connected to the refrigeration system of the refrigeration equipment, and has a second air vent 5111 on it.

[0066] To ensure uniform cold air distribution within the first inner liner 11, the internal airflow path of the first inner liner 11 needs to exit from the rear side of the first inner liner 11. Therefore, an air inlet (the second air outlet 5111 of the air guide 5) and a return air outlet 116 need to be installed on the rear side of the first inner liner 11.

[0067] Therefore, the connecting part 511 with the second air vent 5111 needs to be offset from the return air vent 116 on the rear side of the first inner liner 11, so that the connecting part 511 is off the central axis.

[0068] The first air distribution column 541 and the docking part 511 are deviated in the same direction, so that most of the cold air is directed to the side closer to the return air vent 116, so that the cold air is evenly distributed in the air guide channel 531.

[0069] In some embodiments of this application, the air distribution column 54 further includes a second air distribution column 542, which is arranged in multiple rows along the air inlet direction, and multiple columns are arranged in any row along the vertical air inlet direction. That is, except for the first air distribution column 541 near the docking part 511, the remaining air distribution columns 54 are all second air distribution columns 542.

[0070] It should be noted that the air intake 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 docking part 511 from the second air inlet 5111 (vertical direction).

[0071] Multiple rows and columns of second air distribution columns 542 are staggered to guide the cold air evenly, so that the cold air blown out from the first air outlet 5211 is uniform.

[0072] In some embodiments of this application, the docking part 511 is inclinedly connected to the main body part 53 on the side near the air guide channel 531, so that the cold air in the docking part 511 can flow into the air guide channel 531 more smoothly.

[0073] Regarding the connection method between the cabinet opening component 7 and the air guide component 5, in some embodiments of this application, combined with Figure 9 , 5 A second buckle 5212 is provided on the outer side of the rear wall of the air duct 521. The air duct 521 extends into the first ventilation hole 7211, and the second buckle 5212 is engaged with the air outlet 721 at the position below the rear side of the first ventilation hole 7211.

[0074] By inserting the 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 second clip 5212 is engaged with the air outlet 721 to limit the upward movement of the air guide 5.

[0075] In some embodiments of this application, 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.

[0076] The 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 duct 521 into a plurality of small channels, and the second connecting ribs 5213 overlap the first connecting ribs 7212.

[0077] The 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 second buckle 5212 and the air outlet 721, it plays a limiting role in the vertical direction.

[0078] In some embodiments of this application, the air guide 5 further includes a sealing part 55 disposed on the front side of the air duct 521. The sealing part 55 is supported on the air outlet 721 and located on the front side of the first ventilation hole 7211. The sealing part 55 abuts against the first wall 71 through a sealing member 56.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] Regarding the connection method between the cabinet opening component 7 and the first inner liner 11, in some embodiments of this application, such as... Figure 5 The second wall 72 includes a first connecting part 722 located at the rear end. The cross-section of the first connecting part 722 is C-shaped with the opening facing backward. The front end of the first inner liner 11 is inserted into the C-shaped first connecting part 722.

[0083] 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 C-shaped 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 third buckle 7221. When the cabinet opening part 7 and the first inner liner 11 are inserted front to back, the third buckle 7221 and the slot 1171 are snapped together.

[0084] 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 third 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.

[0085] In some embodiments of this application, combined with Figure 4 , 15 The second wall 72 also includes a number of protrusions 724 extending outward from the air vent 721. The front end of the first inner liner 11 is bent outward to form a front flange 119. The front flange 119 is provided with mating holes 1191 corresponding to the number of protrusions 724. A fastener passes through the mating holes 1191 and is fixed to the protrusions 724.

[0086] Fasteners may be screws, etc. The screws pass through the mating hole 1191 and are screwed into the protrusion 724, thereby further fixing the cabinet opening 7 and the first inner liner 11.

[0087] In some embodiments of this application, the refrigeration device further includes a drawer assembly 6, which includes a drawer body 61 that moves within a first inner liner 11 in a front-rear direction.

[0088] 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 duct 521, 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.

[0089] After the air guide 5 delivers cold air to the first inner liner 11, it 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 cold air from flowing through the food inside the storage cavity 612 and taking away the moisture from the food.

[0090] In some embodiments of this application, such as Figure 11 The top of the first inner liner 11 is provided with a return air vent 116, 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 docking part 511 are spaced apart in the width direction of the refrigeration equipment on the rear side of the first inner liner 11.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] Specifically, 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 duct 521, the first air guide cavity 613 and the second air guide cavity 614 are connected in sequence.

[0095] 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 first 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 outlet 116 located at the top of the first inner liner 11.

[0096] In some embodiments of this application, such as Figure 12 , 13 The first air guide cavity 613 has an opening on the front side, and the drawer assembly 6 also includes a partition 62 that covers the front side of the first air guide cavity 613.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] The divider 62 is connected to the drawer body 61 by a snap-fit, which is convenient and has a simple structure.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] As shown in the figure, 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.

[0111] 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.

[0112] 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.

[0113] In some embodiments of this application, such as Figure 11 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] In some embodiments of this application, such as Figures 14-16 The refrigeration equipment also includes a magnetic field module 2 disposed within the insulation layer on the outside of the first inner liner 11. The magnetic field module 2 is at least partially disposed between the first inner liner 11 and the air guide 5.

[0120] The magnetic field module 2 is fixed to the outside of the first inner liner 11 away from the storage space 110 by fasteners, so as to avoid the magnetic field module 2 being moved by impact force and becoming uneven when the foaming material is foamed in the box 1.

[0121] In some embodiments of this application, the fastener is a soft insulating sheet 3, which is attached between the first inner liner 11 and the magnetic field module 2.

[0122] The flexible release sheet 3 can be a double-sided adhesive PE film, double-sided adhesive, or a film structure formed by the solidification of adhesive.

[0123] The flexible insulating sheet 3 can fix the magnetic field membrane to the first inner liner 11 on the one hand, and on the other hand, the flexible insulating sheet 3, combined with the relatively rigid first inner liner 11 and magnetic field module 2, can fill the gap between the magnetic field module 2 and the first inner liner 11, so that the two fit together and prevent the foaming material from entering from the gap between the magnetic field module 2 and the first inner liner 11 when the box 1 is foamed, so as to prevent the magnetic field module 2 or the first inner liner 11 from deforming.

[0124] In some embodiments of this example, the first inner liner 11 extends toward the side where the magnetic field module 2 is located and is provided with a positioning post 111. The soft insulating sheet 3 and the magnetic field module 2 are provided with a first positioning hole 31 and a second positioning hole 2111 corresponding to the positioning post 111. The positioning post 111 passes through the first positioning hole 31 and the second positioning hole 2111.

[0125] The flexible isolation sheet 3 is prone to deformation and may be accidentally stuck or misplaced during installation. A positioning post 111 is set on the first inner liner 11. First, align the first positioning hole 31 on the flexible isolation sheet 3 with the positioning post 111 so that the flexible isolation sheet 3 is first positioned and stuck to the first inner liner 11. Then, align the second positioning hole 2111 on the magnetic field module 2 with the positioning post 111 so that the magnetic field module 2 is stuck to the flexible isolation sheet 3.

[0126] In some embodiments of this example, a guide plate 112 is also provided on the side of the positioning post 111. The height of the guide plate 112 is lower than that of the positioning post 111, and the guide plate 112 extends away from the positioning post 111 in the direction of the first inner liner 11. The shapes of the first positioning hole 31 and the second positioning hole 2111 are matched with the cross-sectional shape of the positioning post 111 and the guide plate 112 on its side.

[0127] In the diagram, guide plate 112 is connected to positioning post 111. First, coarse positioning is achieved through the higher positioning post 111, and then guidance is provided by the lower guide plate 112, preventing deflection of the flexible insulating plate 3 and the magnetic field module 2. Of course, guide plate 112 and positioning post 111 can also be arranged at intervals.

[0128] In other embodiments of this application, a second screw post 114 is provided on the side of the first inner liner 11 away from the storage space 110, and the magnetic field module 2 is provided with a fixing hole corresponding to the second screw post 114. A screw is passed through the fixing hole and fixed to the second screw post 114, so that the magnetic sheet assembly is fixed to the first inner liner 11.

[0129] In addition to adhesive bonding, the magnetic field module 2 can also be fixed to the first inner liner 11 by screws. Of course, the soft insulating sheet 3 can also be used in combination with adhesive bonding and screw fastening. Screw fastening has strong connection strength, and the soft insulating sheet 3 has the effect of filling gaps to prevent foam material from entering between the magnetic field module 2 and the first inner liner 11.

[0130] In some embodiments of this example, the magnetic field module 2 includes an upper magnetic sheet assembly 21, a lower magnetic sheet assembly 22, and a magnetic conductive element 23 connecting the upper magnetic sheet assembly 21 and the lower magnetic sheet assembly 22; the fixing holes include a first fixing hole 2112, a second fixing hole 2211, and a third fixing hole 231. The first fixing hole 2112 and the second fixing hole 2211 are respectively disposed on the side of the upper magnetic field assembly and the lower magnetic field assembly near the magnetic conductive element 23, and the third fixing hole 231 is disposed on the side of the magnetic conductive element 23 near the upper magnetic field assembly and the lower magnetic field assembly.

[0131] like Figure 14 In the middle, there are two magnetic conductors 23 (the other one is between the two inner liner), and the two ends of the two magnetic conductors 23 are respectively connected to the upper magnetic sheet assembly 21 and the lower magnetic sheet assembly 22.

[0132] The fixing holes are set on the sides where the upper magnetic sheet assembly 21, the magnetic conductor 23 and the lower magnetic sheet assembly 22 are close to each other in sequence. This not only allows the upper magnetic sheet assembly 21, the magnetic conductor 23 and the lower magnetic sheet assembly 22 to be fixed to the first inner liner 11, but also allows the three to be connected in sequence.

[0133] The upper magnetic plate assembly 21 includes an upper uniform magnetic plate 211 and several magnetic plates (not shown). The upper uniform magnetic plate 211 is recessed upwards to form a first clearance cavity 2113, and the several magnetic plates are disposed within the first clearance cavity 2113. The lower magnetic plate assembly 22 includes a lower uniform magnetic plate 221 and several magnetic plates. The lower uniform magnetic plate 221 is recessed downwards to form a second clearance cavity 2212, and the several magnetic plates are disposed within the second clearance cavity 2212. A first fixing hole 2112 is disposed on the upper uniform magnetic plate 211, and a second fixing hole 2211 is disposed on the lower uniform magnetic plate 221. Both the upper uniform magnetic plate 211 and the lower uniform magnetic plate 221 are provided with second positioning holes 2111.

[0134] The upper magnetic sheet assembly 21 may also include an upper positioning member 212. The upper positioning member 212 has the same shape as the first clearance cavity 2113 and is disposed in the first clearance cavity 2113. The upper positioning member 212 forms a plurality of first limiting holes 2121 arranged in rows and columns. Several magnetic sheets are disposed in the first limiting holes 2121. That is, several magnetic sheets are also arranged in rows and columns, but it is not restricted that the distance between each magnetic sheet and the magnetic sheets in its adjacent row or column is the same.

[0135] Correspondingly, the lower magnetic sheet assembly 22 may also include a lower positioning member 222. The structure of the lower positioning member 222 is similar to that of the upper positioning member 212, and it is provided with a second limiting hole 2221.

[0136] In some embodiments of this application, a snap hole 115 is provided at the top of the first inner liner 11; the refrigeration device also includes a sensor assembly 4 that is snapped into the inside of the first inner liner 11 through the snap hole 115.

[0137] The sensor assembly 4 needs to be installed inside the first inner liner 11. In this embodiment, the first inner liner 11 is integrally formed, and it is not possible to process a groove inside the first inner liner 11 for fixing the sensor assembly 4. Therefore, a through-hole 115 is opened on the top of the first inner liner 11 to fix the sensor assembly 4.

[0138] In some embodiments of this application, the sensor assembly 4 includes a sensor 41 and a housing 42 for housing the sensor 41. The top of the housing 42 is provided with a hook 421, which is disposed between adjacent magnetic sheets in the upper magnetic sheet assembly 21.

[0139] The upper magnetic sheet assembly 21 of the magnetic field module 2 is located on the outer side of the top of the first inner liner 11, and the sensor assembly 4 is located on the inner side of the top of the first inner liner 11. The hook 421 on the top of the housing 42 is staggered with the magnetic sheet to avoid mutual interference between the hook 421 and the magnetic sheet.

[0140] The cross section mentioned in this application is not a horizontal section, but a vertical section along the extension length of the corresponding structure.

[0141] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0142] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
