Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a refrigerator. Background Technology

[0002] In refrigerator design, the storage cavity formed by the inner liner is a key space for storing food and other items. To improve storage convenience and space utilization, drawers are usually installed inside the storage cavity. The smooth pulling of the drawers depends on the design of the guide rails, which are located on the side walls of the storage cavity.

[0003] Currently, the common method for installing guide rails is to fasten them to the side wall of the inner liner using screws. While this method ensures the strength of the guide rails, it has significant drawbacks in actual production and assembly. Because each screw needs to be tightened individually, it not only increases the assembly process and steps, but also requires time and manpower for each screw, resulting in low assembly efficiency between the guide rails and the storage cavity, thus affecting the overall assembly efficiency of the refrigerator. Utility Model Content

[0004] This application discloses a refrigerator that can improve the assembly efficiency of the refrigerator.

[0005] To achieve the above objectives, this application discloses a refrigerator, comprising:

[0006] The box has an opening;

[0007] A door body, which is movably disposed within the housing and is used to open or close the opening;

[0008] An inner liner is disposed within the box body, and a foamed cavity is formed between the inner liner and the box body. The foamed cavity is filled with a foam layer. The inner liner forms a storage cavity communicating with the opening, and the storage cavity is provided with:

[0009] A guide rail is detachably disposed on the inner surface of the first sidewall of the storage cavity;

[0010] A drawer is disposed within the storage cavity and is slidably connected to the guide rail so that the drawer can be pushed into or pulled out of the storage cavity;

[0011] The snap-fit ​​structure includes:

[0012] The first snap-fit ​​portion protrudes from the inner surface of the first sidewall of the storage cavity;

[0013] The second latching part is disposed on the guide rail. The second latching part is inserted into the first latching part in the direction in which the drawer is pushed into the storage cavity, so as to prevent the guide rail from moving in the direction perpendicular to the first side wall of the storage cavity and to prevent the guide rail from moving in the height direction of the box.

[0014] A limiting structure is provided between the guide rail and the first side wall of the storage cavity, which is used to prevent the guide rail from moving in the direction of pulling the drawer out of the storage cavity when the second locking part is inserted into the first locking part.

[0015] Since the first latching part protrudes from the inner surface of the first side wall of the storage cavity, and the second latching part is disposed on the guide rail, on the one hand, the first and second latching parts can be detachably disposed, thereby allowing the guide rail to be detachably disposed on the first side wall. On the other hand, by inserting the second latching part into the first latching part in the direction in which the drawer is pushed into the storage cavity, the freedom of the guide rail can be limited both in the direction perpendicular to the first side wall of the storage cavity and in the height direction of the cabinet, thereby preventing the guide rail from moving in the direction perpendicular to the first side wall of the storage cavity and preventing the guide rail from moving in the height direction of the cabinet. Furthermore, since the limiting structure is disposed between the guide rail and the first side wall of the storage cavity, and the second latching part is inserted into the first latching part... The limiting structure prevents the guide rail from moving in the direction the drawer is pulled out of the storage cavity. Therefore, the limiting structure can restrict the degree of freedom of the guide rail in the direction the drawer is pulled out of the storage cavity, thus preventing the guide rail from detaching from the first side wall as the drawer is pulled out of the storage cavity. In this way, the degree of freedom of the guide rail in different directions can be limited through the snap-fit ​​structure and the limiting structure. On the one hand, this ensures the stability and reliability of the guide rail set on the first side wall. On the other hand, compared with using screws to assemble the guide rail to the first side wall, it can greatly shorten the time for assembling the guide rail to the first side wall, thereby improving the assembly efficiency of the guide rail, thus improving the assembly efficiency of the refrigerator, and also saving certain labor costs and reducing the production cost of the refrigerator.

[0016] In one possible implementation, the first latching portion includes:

[0017] A snap-fit ​​shaft is connected to the first side wall of the storage cavity;

[0018] A first boss is located at the end of the snap-fit ​​shaft away from the first sidewall of the storage cavity, and the diameter of the first boss is larger than the diameter of the snap-fit ​​shaft.

[0019] The second snap-fit ​​portion includes:

[0020] A slot is provided on the snap-fit ​​shaft, and the width of the slot is smaller than the diameter of the first boss.

[0021] Since the diameter of the first boss is larger than the diameter of the locking shaft, and the slot is engaged with the locking shaft, the engagement of the slot with the locking shaft can prevent the guide rail from moving along the height direction of the housing. Since the width of the slot is smaller than the diameter of the first boss, the first boss can prevent the slot from disengaging from the locking shaft along the axial direction of the locking shaft, thereby preventing the guide rail from moving in a direction perpendicular to the first side wall.

[0022] In one possible implementation, the first latching portion further includes:

[0023] The second boss is connected to the end of the snap-fit ​​shaft away from the first boss. The second boss is connected to the first sidewall of the storage cavity. The diameter of the second boss is larger than the diameter of the snap-fit ​​shaft. The snap-fit ​​groove is engaged between the first boss and the second boss.

[0024] Since the second boss is connected to the end of the locking shaft away from the first boss, and the diameter of the second boss is larger than the diameter of the locking shaft, the slot is engaged between the first boss and the second boss. Therefore, the first boss and the second boss can limit the degree of freedom of the slot in the direction perpendicular to the first sidewall, thereby preventing the guide rail from moving in the direction perpendicular to the first sidewall.

[0025] In one possible implementation, the first latching portion further includes:

[0026] A fixing seat is disposed inside the foaming cavity, and the fixing seat is connected to the end face of the second boss away from the snap-fit ​​shaft;

[0027] A through-hole is provided on the first side wall of the storage cavity, and the second boss is inserted into the through-hole. The projection of the fixing seat on the first side wall in a direction perpendicular to the first side wall of the storage cavity covers the through-hole.

[0028] Since the fixing seat is located inside the foaming cavity and the second protrusion passes through the connecting through hole, when installing the first snap-fit ​​part, firstly, the snap-fit ​​shaft and the first protrusion extend out of the connecting through hole, then the second protrusion passes through the connecting through hole, and the inner liner is connected to the box body. Finally, foaming is performed inside the foaming cavity so that the fixing seat is fixed inside the foaming cavity. Thus, the fixing seat is fixed to the surface of the first side wall facing the foaming cavity, thereby preventing the first snap-fit ​​part from moving towards the foaming cavity.

[0029] Furthermore, since the projection of the fixing seat onto the first side wall in a direction perpendicular to the first side wall of the storage cavity covers the connecting through hole, the connecting through hole can prevent the fixing seat from passing through the connecting through hole, thereby ensuring the stability and reliability of the first snap-fit ​​part set on the first side wall.

[0030] In one possible implementation, the guide rail has:

[0031] A guide surface, the guide surface being away from the first side wall of the storage cavity, the guide surface being provided with a guide groove extending along the pull-out direction of the drawer, the guide groove being slidably connected to the drawer;

[0032] The connecting surface is provided with a snap-fit ​​part and a connecting part. The snap-fit ​​part is opposite to the connecting surface and has a gap with the connecting surface. The snap-fit ​​part is connected to the connecting surface through the connecting part. The connecting part encloses and forms a receiving space. The first boss is located in the receiving space. The slot is provided on the snap-fit ​​part. The width of the slot is smaller than the diameter of the first boss.

[0033] Therefore, by setting guide grooves on the guide surface, the drawer can be guided, ensuring the consistency of its movement trajectory and the smoothness of the drawer during the pulling process.

[0034] In addition, since the snap-fit ​​part is opposite to the connecting surface and there is a gap between them, the snap-fit ​​part is connected to the connecting surface through the connecting part, and the connecting part encloses and forms a receiving space. The first boss is located in the receiving space, and the slot is provided on the snap-fit ​​part. The width of the slot is smaller than the diameter of the first boss. Therefore, the first boss can be limited while being received, preventing the first boss from leaving the slot in a direction perpendicular to the first slot wall.

[0035] As can be seen, the above structural design can achieve the purpose of connecting the first and second snap-fit ​​parts, and also simplify the structural design of the first and second snap-fit ​​parts.

[0036] In one possible implementation, the limiting structure includes a slot opening facing the direction of the drawer pull-out receiving cavity. Along the height direction of the box body, the width of the slot opening is smaller than the width of the slot, and the width of the locking shaft is greater than the width of the slot opening. The locking shaft enters the slot through the slot opening.

[0037] Because the width of the slot opening is smaller than the width of the card slot along the height of the cabinet, the slot opening is tightened. As a result, the snap-fit ​​shaft entering the card slot through the slot opening can be initially limited by the slot opening, thus preventing the snap-fit ​​shaft from leaving the card slot through the slot opening. This improves the stability of the snap-fit ​​shaft and the card slot in the direction of the drawer being pulled out of the receiving cavity to a certain extent.

[0038] In addition, since the slot of the card slot faces the direction of the drawer being pulled out of the receiving cavity, the locking shaft enters the card slot through the slot of the card slot. Therefore, it is possible to achieve the purpose of the first locking part being inserted into the second locking part along the direction of the drawer being pulled out of the receiving cavity.

[0039] In one possible implementation, the limiting structure further includes:

[0040] A first limiting part is provided on the inner surface of the first side wall of the storage cavity, and the first limiting part has an abutting surface that is opposite to the opening.

[0041] The second limiting part is disposed on the guide rail. The second limiting part has a first limiting wall and a second limiting wall that are opposite to each other and spaced apart. Both the first limiting wall and the second limiting wall are provided with limiting protrusions that protrude toward each other. The first limiting part is inserted between the first limiting wall and the second limiting wall, and the limiting protrusion abuts against the abutting surface to prevent the guide rail from moving in the direction in which the drawer is pulled out of the storage cavity.

[0042] Since the contact surface is located at the first limiting part and is away from the opening, and the first limiting part protrudes from the inner surface of the first sidewall, the contact surface is also protruding from the inner surface of the first sidewall.

[0043] Furthermore, since the second limiting part has opposing and spaced first and second limiting walls, each with limiting protrusions protruding towards each other, when the first and second limiting parts engage, as the guide rail moves toward the drawer into the storage cavity, the first limiting part can be inserted between the first and second limiting walls. As the guide rail continues to move, the limiting protrusions on the first and second limiting walls will abut against the outer peripheral wall of the first limiting part. Because the limiting protrusions on the first and second limiting walls reduce the distance between them, as the guide rail continues to push the drawer in... During the movement, the limiting protrusions on the first and second limiting walls can move relative to the peripheral wall of the first limiting part, and the first and second limiting walls can move away from each other until the limiting protrusions on the first and second limiting walls disengage from the outer peripheral wall of the first limiting part. At this point, the first and second limiting walls return to their original positions. When the limiting protrusions disengage from the outer peripheral wall of the first limiting part, they will abut against the contact surface. In this way, the cooperation between the first and second limiting parts is completed. At the same time, by the limiting protrusions abutting against the contact surface, the movement of the guide rail along the direction of the drawer being pulled out of the storage cavity can be prevented, further ensuring the stability and reliability of the guide rail set on the first side wall.

[0044] In one possible implementation, the first limiting portion further includes a locking groove disposed on the abutting surface:

[0045] The second limiting part also includes:

[0046] The third limiting wall is disposed between the first limiting wall and the second limiting wall. The third limiting wall has a protruding locking protrusion along the direction in which the drawer is pushed into the receiving cavity. When the first limiting part extends between the first limiting wall and the second limiting wall, the locking protrusion cooperates with the locking groove to prevent the guide rail from moving along the height direction of the box.

[0047] Therefore, by using the engagement of the protrusion and the groove, the degree of freedom of the guide rail in the height direction of the housing can be further limited, thereby further improving the stability and reliability of the guide rail in the height direction of the housing.

[0048] In one possible implementation, reinforcing ribs are provided on the connecting surface.

[0049] By adding reinforcing ribs to the connecting surface, the strength of the connecting surface can be improved, thereby increasing the overall strength of the guide rail and preventing the guide rail from deforming during the sliding connection between the drawer and the guide rail.

[0050] In one possible implementation, the guide groove is provided with:

[0051] The mounting groove is disposed on the groove wall of the guide groove away from the opening;

[0052] A cushioning pad is disposed in the mounting groove, and the cushioning pad is able to abut against the drawer when the drawer is pushed into the storage cavity.

[0053] Therefore, by using a cushioning pad to abut against the drawer, on the one hand, it can prevent the drawer from colliding with the side wall of the storage cavity and making noise when it is pushed into the storage cavity, and on the other hand, it can protect the drawer and thus improve its service life.

[0054] Compared with the prior art, the beneficial effects of this application are as follows:

[0055] Because the first latching part protrudes from the inner surface of the first side wall of the storage cavity, and the second latching part is disposed on the guide rail, on the one hand, the first and second latching parts can be detachably disposed, thereby allowing the guide rail to be detachably disposed on the first side wall. On the other hand, by inserting the second latching part into the first latching part in the direction in which the drawer is pushed into the storage cavity, the freedom of the guide rail can be limited both in the direction perpendicular to the first side wall of the storage cavity and in the height direction of the cabinet, thereby preventing the guide rail from moving in the direction perpendicular to the first side wall of the storage cavity and preventing the guide rail from moving in the height direction of the cabinet. Furthermore, because the limiting structure is disposed between the guide rail and the first side wall of the storage cavity, and When the second locking part is inserted into the first locking part, it prevents the guide rail from moving in the direction of pulling the drawer out of the storage cavity. Therefore, the limiting structure can limit the degree of freedom of the guide rail in the direction of pulling the drawer out of the storage cavity, thereby preventing the guide rail from detaching from the first side wall as the drawer is pulled out of the storage cavity. In this way, the degree of freedom of the guide rail in different directions can be limited by the locking structure and the limiting structure. On the one hand, it ensures the stability and reliability of the guide rail set on the first side wall. On the other hand, compared with using screws to assemble the guide rail to the first side wall, it can greatly shorten the time of assembling the guide rail to the first side wall, thereby improving the assembly efficiency of the guide rail and thus improving the assembly efficiency of the refrigerator.

[0083] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0084] In refrigerator design, the storage cavity formed by the inner liner is a key space for storing food and other items. To improve storage convenience and space utilization, drawers are usually installed inside the storage cavity. The smooth pulling of the drawers depends on the design of the guide rails, which are located on the side walls of the storage cavity.

[0085] Currently, the common method for installing guide rails is to fasten them to the side wall of the inner liner using screws. While this method ensures the strength of the guide rails, it has significant drawbacks in actual production and assembly. Because each screw needs to be tightened individually, it not only increases the assembly process and steps, but also requires time and manpower for each screw, resulting in low assembly efficiency between the guide rails and the storage cavity, thus affecting the overall assembly efficiency of the refrigerator. Therefore, this application provides a refrigerator to solve the above problems.

[0086] The technical solution of this application will be described below with reference to specific embodiments and accompanying drawings.

[0087] This application provides a refrigerator 100. Figure 1 This application provides an implementation method for a refrigerator 100.

[0088] The refrigerator 100 can achieve refrigeration in modes including but not limited to direct cooling, air cooling, and hybrid cooling (direct cooling and air cooling). This embodiment mainly uses air cooling as an example for illustration. Optionally, the refrigerator 100 is equipped with a refrigeration system and an air duct system. The refrigeration system is used to generate cold air, and the air duct system can transport the cold air generated by the refrigeration system to the refrigerator compartment and the freezer compartment of the refrigerator 100 to achieve the purpose of refrigeration in the refrigerator compartment and freezing in the freezer compartment.

[0089] A refrigeration system typically refers to a closed system consisting of components such as a compressor, evaporator, condenser, dryer filter, return gas pipe, and throttling device, as well as refrigerant. Each component is distributed in different locations within the refrigerator 100 according to its structural characteristics to meet the requirements of its corresponding function.

[0090] The working process of a refrigeration system mainly includes compression, condensation, throttling, and evaporation.

[0091] The compression process is as follows: After plugging in the power cord of the refrigerator 100, the compressor starts to work when the contacts of the thermostat are closed. The low-temperature and low-pressure refrigerant from the evaporator is drawn into the compressor and compressed into a high-temperature and high-pressure refrigerant gas by the compressor before being discharged into the condenser.

[0092] The condensation process is as follows: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and it is gradually cooled into room-temperature and high-pressure refrigerant saturated vapor, and then cooled into refrigerant saturated liquid.

[0093] The throttling process is as follows: the condensed saturated liquid refrigerant is filtered through a dryer to remove moisture and impurities before flowing into the throttling device. The throttling device reduces the pressure and turns the refrigerant into a low-pressure, room-temperature wet vapor.

[0094] Evaporation process: Room temperature and low pressure wet vapor enters the evaporator, begins to absorb heat and vaporize, lowers the temperature of the evaporator and its surroundings, achieves refrigeration, and also turns the refrigerant into a low temperature and low pressure gas.

[0095] The refrigerant that comes out of the evaporator returns to the compressor and repeats the above process. Energy is converted through the change in the state of the refrigerant, and the heat inside the refrigerator 100 is transferred to the outside air, thereby realizing the refrigeration cycle of the refrigerator 100.

[0096] Figure 2 This is a schematic diagram of the door 120 with its opening 111 not closed, provided in an embodiment of this application. See also, in some possible embodiments, [the diagram is shown in the original text]. Figure 1 and Figure 2 The refrigerator 100 includes a cabinet 110, on which an opening 111 is provided. The cabinet 110 can be a two-door cabinet 110, a four-door cabinet 110, etc., which are not limited here. Those skilled in the art can design it according to actual needs.

[0097] In addition, the dimensions of the enclosure 110 are not limited, and those skilled in the art can make corresponding designs according to the actual installation space and storage capacity requirements.

[0098] In some possible embodiments, the refrigerator 100 also includes a door 120, which is movably disposed on the cabinet 110 and is used to open or close the opening 111.

[0099] The connection methods between the door 120 and the box 110 include, but are not limited to, the door 120 and the box 110 being connected by a pivot, or the door 120 and the box 110 being connected by a hinge.

[0100] Optionally, the door 120 is rotatable relative to the housing 110, and the door 120 is capable of rotating toward the opening 111 to close the opening 111, or rotating away from the opening 111 to open the opening 111.

[0101] In some possible embodiments, see Figure 1 and Figure 2 The refrigerator 100 also includes an inner liner 130, which is disposed inside the cabinet 110 and forms a foam cavity between the inner liner 130 and the cabinet 110. The foam cavity is used to fill the foam layer, and the inner liner 130 forms a storage cavity 131 that communicates with the opening 111.

[0102] The inner liner 130 is connected to the cabinet 110. The gap between the inner liner 130 and the cabinet 110 is a foaming cavity. Foaming is performed in the foaming cavity to form a foam layer, which is used to keep the refrigerator 100 warm.

[0103] Since the inner liner 130 forms a storage cavity 131 that communicates with the opening 111, when freezing or refrigerating items, the door 120 is opened first to facilitate placing items into the storage cavity 131, and then the door 120 is closed to isolate the storage cavity 131 from the outside world for frequent freezing or refrigeration.

[0104] Figure 3 This is a schematic diagram of the assembly of the storage cavity 131 and the guide rail 140 provided in an embodiment of this application. See also the following in some possible embodiments: Figure 2 and Figure 3 The storage cavity 131 is provided with a guide rail 140 and a drawer 150. The guide rail 140 is detachably provided on the inner surface of the first side wall 1311 of the storage cavity 131. The drawer 150 is provided in the storage cavity 131 and is slidably connected to the guide rail 140 so that the drawer 150 can be pushed into or pulled out of the storage cavity 131.

[0105] The storage cavity 131 includes two first sidewalls 1311, which are arranged opposite to each other. The inner surface of the first sidewall 1311 refers to the surface facing the internal space of the storage cavity 131. The storage cavity 131 also includes a second sidewall, which is opposite to the opening 111 and is connected to the two first sidewalls 1311 respectively.

[0106] Since the guide rail 140 is detachably mounted on the inner surface of the first side wall 1311 of the storage cavity 131, the guide rail 140 can be removed when the drawer 150 is not required in the storage cavity 131, and the guide rail 140 can be mounted on the first side wall 1311 when the drawer 150 is installed in the storage cavity 131, thus improving the flexibility of the guide rail 140 mounting.

[0107] In addition, when the guide rail 140 is damaged, it can also be disassembled for repair, which improves the convenience of repairing the guide rail 140.

[0108] Figure 4 An exploded view of the inner liner 130 and guide rail 140 provided in an embodiment of this application. Figure 5 A schematic diagram of the guide rail 140 from a first-view perspective provided in an embodiment of this application. See also, in some possible embodiments, [the following is a separate section:] Figure 4 and Figure 5The storage cavity 131 is also provided with a snap-fit ​​structure 160, which includes a first snap-fit ​​part 161 and a second snap-fit ​​part 162. The first snap-fit ​​part 161 protrudes from the inner surface of the first side wall 1311 of the storage cavity 131. The second snap-fit ​​part 162 is disposed on the guide rail 140. The second snap-fit ​​part 162 is inserted into the first snap-fit ​​part 161 in the direction in which the drawer 150 is pushed into the storage cavity 131, so as to prevent the guide rail 140 from moving in the direction perpendicular to the first side wall 1311 of the storage cavity 131 and to prevent the guide rail 140 from moving in the height direction of the cabinet 110.

[0109] Among them, such as Figure 4 As shown, the direction in which drawer 150 is pulled out is as indicated by the Y arrow, the direction in which drawer 150 is pushed into storage cavity 131 is as indicated by the y arrow, the height direction of box 110 is as indicated by the Z arrow, and the direction along the first side wall 1311 perpendicular to the storage cavity 131 is as indicated by the X arrow.

[0110] In addition, the specific structures of the first snap-fit ​​portion 161 and the second snap-fit ​​portion 162 mentioned above include various types, such as: one of the first snap-fit ​​portion 161 and the second snap-fit ​​portion 162 is a hole-like structure and the other is a protrusion structure, or one of the first snap-fit ​​portion 161 and the second snap-fit ​​portion 162 is a groove-like structure and the other is a hook structure, etc.

[0111] Since the second latching part 162 is inserted into the first latching part 161 in the direction of the drawer 150 being pushed into the storage cavity 131, on the one hand, the guide rail 140 can be detachably assembled onto the first side wall 1311 in the direction of the drawer 150 being pushed into the storage cavity 131. On the other hand, the degree of freedom of the guide rail 140 can be limited in the direction perpendicular to the first side wall 1311 of the storage cavity 131, and the degree of freedom of the guide rail 140 can also be limited in the height direction of the box body 110, thereby preventing the guide rail 140 from moving in the direction perpendicular to the first side wall 1311 of the storage cavity 131 and preventing the guide rail 140 from moving in the height direction of the box body 110.

[0112] In some possible embodiments, see Figure 4 The storage cavity 131 is also provided with a limiting structure 170. The limiting structure 170 is located between the guide rail 140 and the first side wall 1311 of the storage cavity 131. It is used to prevent the guide rail 140 from moving in the direction of the drawer 150 being pulled out of the storage cavity 131 when the second locking part 162 is inserted into the first locking part 161.

[0113] As can be seen from the above embodiments, since the first latching part 161 protrudes from the inner surface of the first side wall 1311 of the storage cavity 131, and the second latching part 162 is disposed on the guide rail 140, on the one hand, the first latching part 161 and the second latching part can be detachably disposed, thereby enabling the guide rail 140 to be detachably disposed on the first side wall 1311; on the other hand, the second latching part 162 is inserted into the first latching part 161 in the direction in which the drawer 150 is pushed into the storage cavity 131. The limiting structure 170 can restrict the degree of freedom of the guide rail 140 in both the direction perpendicular to the first side wall 1311 of the storage cavity 131 and the height direction of the box body 110, thereby preventing the guide rail 140 from moving in the direction perpendicular to the first side wall 1311 of the storage cavity 131 and preventing the guide rail 140 from moving in the height direction of the box body 110. Furthermore, since the limiting structure 170 is disposed between the guide rail 140 and the first side wall 1311 of the storage cavity 131, and in the second engaging portion 1... When 62 is inserted into the first latching part 161, it prevents the guide rail 140 from moving in the direction of the drawer 150 being pulled out of the storage cavity 131. Therefore, the limiting structure 170 can limit the degree of freedom of the guide rail 140 in the direction of the drawer 150 being pulled out of the storage cavity 131. Thus, during the process of the drawer 150 being pulled out of the storage cavity 131, the guide rail 140 is prevented from detaching from the first side wall 1311 with the drawer 150. In this way, the degree of freedom of the guide rail 140 in different directions can be limited by the latching structure 160 and the limiting structure 170. On the one hand, this ensures the stability and reliability of the guide rail 140 set on the first side wall 1311. On the other hand, compared with using screws to assemble the guide rail 140 to the first side wall 1311, it can greatly shorten the time for assembling the guide rail 140 to the first side wall 1311. This improves the assembly efficiency of the guide rail 140, thereby improving the assembly efficiency of the refrigerator 100. It can also save certain labor costs and reduce the production cost of the refrigerator 100.

[0114] Alternatively, the first latching portion 161 and the second latching portion 162 may each include multiple portions, with each multiple first latching portion 161 and multiple second latching portions 162 corresponding one-to-one and spaced apart along the pull-out direction of the drawer 150, so as to further improve the reliability of the detachable connection to the guide rail 140.

[0115] Figure 6 This is a schematic diagram of the structure of the first latching portion 161 provided in an embodiment of this application. See also, in some possible embodiments, [the following text is missing]. Figure 4 , Figure 5 and Figure 6The first snap-fit ​​portion 161 includes a snap-fit ​​shaft 1611 and a first boss 1612. The snap-fit ​​shaft 1611 is connected to the first side wall 1311 of the storage cavity 131. The first boss 1612 is disposed at the end of the snap-fit ​​shaft 1611 away from the first side wall 1311 of the storage cavity 131, and the diameter of the first boss 1612 is larger than the diameter of the snap-fit ​​shaft 1611.

[0116] The second snap-fit ​​part 162 includes a snap-fit ​​groove 1621, which is snapped onto the snap-fit ​​shaft 1611. The width of the snap-fit ​​groove 1621 is smaller than the diameter of the first boss 1612.

[0117] Since the diameter of the first boss 1612 is larger than the diameter of the locking shaft 1611, the locking groove 1621 is engaged with the locking shaft 1611. Therefore, the engagement of the locking groove 1621 with the locking shaft 1611 can prevent the guide rail 140 from moving along the height direction of the housing 110. Since the width of the locking groove 1621 is smaller than the diameter of the first boss 1612, the first boss 1612 can prevent the locking groove 1621 from disengaging from the locking shaft 1611 along the axial direction of the locking shaft 1611, thereby preventing the guide rail 140 from moving in a direction perpendicular to the first side wall 1311.

[0118] Alternatively, the snap-fit ​​shaft 1611 and the first boss 1612 can be integrally formed, which can reduce the number of assembly parts of the refrigerator 100 and thus improve the assembly efficiency of the refrigerator 100.

[0119] In some possible embodiments, see Figure 4 , Figure 5 and Figure 6 The first snap-fit ​​portion 161 also includes a second protrusion 1613. The second protrusion 1613 is connected to the end of the snap-fit ​​shaft 1611 away from the first protrusion 1612. The second protrusion 1613 is connected to the first sidewall 1311 of the storage cavity 131. The diameter of the second protrusion 1613 is larger than the diameter of the snap-fit ​​shaft 1611. The snap-fit ​​groove 1621 is snapped between the first protrusion 1612 and the second protrusion 1613.

[0120] Since the second boss 1613 is connected to the end of the snap-fit ​​shaft 1611 away from the first boss 1612, and the diameter of the second boss 1613 is larger than the diameter of the snap-fit ​​shaft 1611, the slot 1621 is snapped between the first boss 1612 and the second boss 1613. Therefore, the first boss 1612 and the second boss 1613 can limit the degree of freedom of the slot 1621 in the direction perpendicular to the first sidewall 1311, thereby preventing the guide rail 140 from moving in the direction perpendicular to the first sidewall 1311.

[0121] In addition, the connection structure between the second boss 1613 and the first sidewall 1311 includes, but is not limited to, adhesive connection between the second boss 1613 and the first sidewall 1311, or snap-fit ​​connection between the second boss 1613 and the first sidewall 1311.

[0122] In some other possible embodiments, the first snap-fit ​​portion 161 includes a snap-fit ​​protrusion and a snap-fit ​​groove disposed on the snap-fit ​​protrusion. The snap-fit ​​groove is disposed circumferentially along the snap-fit ​​protrusion. The snap-fit ​​groove 1621 snaps into the snap-fit ​​groove. The groove wall of the snap-fit ​​groove away from the first side wall 1311 can prevent the snap-fit ​​groove 1621 from moving axially along the snap-fit ​​protrusion.

[0123] Figure 7 This is a cross-sectional view of the inner liner 130 provided in an embodiment of this application. Figure 8 for Figure 7 A partially enlarged schematic diagram at point A in the middle; see also [reference] in some possible embodiments. Figure 6 , Figure 7 and Figure 8 The first snap-fit ​​part 161 also includes a fixing seat 1614, which is disposed in the foaming cavity. The fixing seat 1614 is connected to the end face of the second boss 1613 away from the snap-fit ​​shaft 1611. A through connection hole 1312 is provided on the first side wall 1311 of the storage cavity 131. The second boss 1613 passes through the through connection hole 1312. The projection of the fixing seat 1614 on the first side wall 1311 along a direction perpendicular to the first side wall 1311 of the storage cavity 131 covers the through connection hole 1312.

[0124] Since the fixing seat 1614 is located inside the foaming cavity and the second protrusion 1613 passes through the connecting through hole 1312, when installing the first snap-fit ​​part 161, the snap-fit ​​shaft 1611 and the first protrusion 1612 are first extended out of the connecting through hole 1312, then the second protrusion 1613 passes through the connecting through hole 1312, and the inner liner 130 is connected to the box body 110. Finally, foaming is performed inside the foaming cavity so that the fixing seat 1614 is fixed inside the foaming cavity. Thus, the fixing seat 1614 is fixed to the surface of the first side wall 1311 facing the foaming cavity, thereby preventing the first snap-fit ​​part 161 from moving towards the foaming cavity.

[0125] Furthermore, since the projection of the fixing seat 1614 on the first side wall 1311 along the direction perpendicular to the first side wall 1311 of the storage cavity 131 covers the connecting through hole 1312, the connecting through hole 1312 can prevent the fixing seat 1614 from passing through the connecting through hole 1312, thereby ensuring the stability and reliability of the first snap-fit ​​part 161 disposed on the first side wall 1311.

[0126] In addition, the projection of the fixing seat 1614 onto the first side wall 1311 along the direction perpendicular to the first side wall 1311 of the storage cavity 131 covers the connecting through hole 1312. It should be understood that the width of the fixing seat 1614 is greater than the diameter of the connecting through hole 1312, and the width direction of the fixing seat 1614 is parallel to the first side wall 1311.

[0127] Optionally, the fixing seat 1614, the second boss 1613, the snap-fit ​​shaft 1611, and the first boss 1612 are all integrally formed, which improves the efficiency of setting the first snap-fit ​​part 161.

[0128] Of course, in some other possible embodiments, the fixing seat 1614 and the second boss 1613 are independent components. In this way, the fixing seat 1614 can be placed in the foaming cavity first, and then the second boss 1613 passes through the connecting through hole 1312 and connects to the fixing seat 1614. The diameter of the second boss 1613 can be larger than the diameter of the connecting through hole 1312.

[0129] Figure 9 This is a schematic diagram of the guide rail 140 from a second perspective, provided in an embodiment of this application. Figure 10 A schematic diagram of the guide rail 140 from a third-view perspective provided in an embodiment of this application; see also, in some possible embodiments, [see...]. Figure 9 and Figure 10 The guide rail 140 has a guide surface 141 and a connecting surface 142. The guide surface 141 is away from the first side wall 1311 of the storage cavity 131. A guide groove 1411 extending along the pull-out direction of the drawer 150 is provided on the guide surface 141. The guide groove 1411 is slidably connected to the drawer 150. A snap-fit ​​part 1421 and a connecting part 1422 are provided on the connecting surface 142. The snap-fit ​​part 1421 is opposite to the connecting surface 142 and there is a gap between them. The snap-fit ​​part 1421 is connected to the connecting surface 142 through the connecting part 1422. The connecting part 1422 encloses and forms an accommodating space 1423. A first boss 1612 is located in the accommodating space 1423. A slot 1621 is provided on the snap-fit ​​part 1421. The width of the slot 1621 is smaller than the diameter of the first boss 1612.

[0130] Therefore, by setting guide groove 1411 on guide surface 141, drawer 150 can be guided, ensuring the consistency of its movement trajectory and the smoothness of drawer 150 during the pulling process.

[0131] Furthermore, since the snap-fit ​​portion 1421 is opposite to the connecting surface 142 and there is a gap between them, the snap-fit ​​portion 1421 is connected to the connecting surface 142 through the connecting portion 1422. The connecting portion 1422 encloses and forms a receiving space 1423. The first boss 1612 is located in the receiving space 1423. The slot 1621 is provided on the snap-fit ​​portion 1421. The width of the slot 1621 is smaller than the diameter of the first boss 1612. Therefore, when the first boss 1612 is received, it can be limited to prevent the first boss 1612 from leaving the slot 1621 in a direction perpendicular to the first slot wall.

[0132] As can be seen, the above structural design can achieve the purpose of connecting the first snap-fit ​​part 161 and the second snap-fit ​​part 162, and can also simplify the structural design of the first snap-fit ​​part 161 and the second snap-fit ​​part 162.

[0133] Optional, such as Figure 10 As shown, the connecting part 1422 includes a first connecting surface, a second connecting surface and a third connecting surface connected in sequence, and the first connecting surface, the second connecting surface and the third connecting surface enclose a receiving space 1423.

[0134] Figure 11 This is a partial schematic diagram of the guide rail 140 provided in real time for this application, showing its third-person perspective. Figure 12 A schematic diagram of the first limiting portion 172 provided in an embodiment of this application; see also, in some possible embodiments, [reference needed]. Figure 10 , Figure 11 and Figure 12 The limiting structure 170 includes a slot 171 of a card slot 1621. The slot 171 of the card slot 1621 faces the direction in which the drawer 150 is pulled out of the receiving cavity. Along the height direction of the box body 110, the width of the slot 171 of the card slot 1621 is less than the width of the card slot 1621, and the width of the locking shaft 1611 is greater than the width of the slot 171 of the card slot 1621. The locking shaft 1611 enters the card slot 1621 through the slot 171 of the card slot 1621.

[0135] Since the width of the slot 171 of the slot 1621 is smaller than the width of the slot 1621 along the height direction of the cabinet 110, the slot 171 of the slot 1621 is tightened in size. As a result, the snap-fit ​​shaft 1611 that enters the slot 1621 through the slot 171 of the slot 1621 can be initially limited by the slot 171 of the slot 1621, thereby preventing the snap-fit ​​shaft 1611 from leaving the slot 1621 through the slot 171 of the slot 1621. This improves the stability of the snap-fit ​​shaft 1611 and the slot 1621 in the direction in which the drawer 150 is pulled out of the receiving cavity to a certain extent.

[0136] In addition, since the slot 171 of the card slot 1621 faces the direction of the drawer 150 being pulled out of the receiving cavity, the locking shaft 1611 enters the card slot 1621 through the slot 171 of the card slot 1621. Therefore, the purpose of the first locking part 161 being inserted into the second locking part 162 along the direction of the drawer 150 being pulled out of the receiving cavity can be achieved.

[0137] In some possible embodiments, see Figure 11 and Figure 12 The limiting structure 170 also includes a first limiting part 172 and a second limiting part 173. The first limiting part 172 protrudes from the inner surface of the first side wall 1311 of the storage cavity 131 and has an abutment surface 1721 facing away from the opening 111. The second limiting part 173 is disposed on the guide rail 140 and has a first limiting wall 1731 and a second limiting wall 1732 that are opposite to each other and spaced apart. The first limiting wall 1731 and the second limiting wall 1732 are each provided with a limiting protrusion 1733 that protrudes toward each other. The first limiting part 172 is inserted between the first limiting wall 1731 and the second limiting wall 1732, and the limiting protrusion 1733 abuts against the abutment surface 1721 to prevent the guide rail 140 from moving in the direction in which the drawer 150 is pulled out of the storage cavity 131.

[0138] Since the contact surface 1721 is located at the first limiting part 172 and is away from the opening 111, and the first limiting part 172 protrudes from the inner surface of the first side wall 1311, the contact surface 1721 is also protruding from the inner surface of the first side wall 1311.

[0139] Furthermore, since the second limiting part 173 has a first limiting wall 1731 and a second limiting wall 1732 that are opposite to and spaced apart, and both the first limiting wall 1731 and the second limiting wall 1732 are provided with limiting protrusions 1733 that protrude toward each other, when the first limiting part 172 and the second limiting part 173 are engaged, as the guide rail 140 moves toward the drawer 150 into the storage cavity 131, the first limiting part 172 can be inserted between the first limiting wall 1731 and the second limiting wall 1732. As the guide rail 140 continues to move, the limiting protrusions 1733 on the first limiting wall 1731 and the second limiting arm will abut against the outer peripheral wall of the first limiting part 172. Because the provision of the limiting protrusions 1733 on the first limiting wall 1731 and the second limiting arm reduces the distance between the first limiting wall 1731 and the second limiting wall 1732, therefore, as the guide rail 140 continues to move toward the drawer 150... During movement, the limiting protrusions 1733 on the first limiting wall 1731 and the second limiting wall 1732 can move relative to the peripheral wall of the first limiting portion 172, and the first limiting wall 1731 and the second limiting wall 1732 can move away from each other until the limiting protrusions 1733 on the first limiting wall 1731 and the second limiting wall 1732 disengage from the outer peripheral wall of the first limiting portion 172, at which point the first limiting wall 1731 and the second limiting wall 1732 return to their original positions. When the limiting protrusion 1733 disengages from the outer peripheral wall of the first limiting part 172, it will abut against the abutment surface 1721. In this way, the cooperation between the first limiting part 172 and the second limiting part 173 is completed. At the same time, by the limiting protrusion 1733 abutting against the abutment surface 1721, the guide rail 140 can be prevented from moving in the direction of the drawer 150 being pulled out of the storage cavity 131, which further ensures the stability and reliability of the guide rail 140 set on the first side wall 1311.

[0140] Optionally, the first limiting part 172 is a square prism, such as a rectangular prism. The two side walls of the rectangular prism in the height direction of the box 110 are the outer peripheral walls of the first limiting wall 1731 mentioned above, while the side wall opposite to the opening 111 and away from the opening 111 is the abutment surface 1721.

[0141] In some possible embodiments, see Figure 11 and Figure 12 The first limiting part 172 also includes a locking groove 1722 disposed on the abutment surface 1721; the second limiting part 173 also includes a third limiting wall 1734 disposed between the first limiting wall 1731 and the second limiting wall 1732. The third limiting wall 1734 has a locking protrusion 1735 protruding along the direction in which the drawer 150 is pushed into the receiving cavity. When the first limiting part 172 extends into the space between the first limiting wall 1731 and the second limiting wall 1732, the locking protrusion 1735 engages with the locking groove 1722 to prevent the guide rail 140 from moving along the height direction of the box 110.

[0142] Therefore, by engaging the protrusion 1735 with the groove 1722, the degree of freedom of the guide rail 140 in the height direction of the housing 110 can be further limited, thereby further improving the stability and reliability of the guide rail 140 in the height direction of the housing 110.

[0143] Optionally, the 1735 embossing can be plate-shaped or strip-shaped.

[0144] In some possible embodiments, see Figure 10 A reinforcing rib 1424 is provided on the connecting surface 142.

[0145] By setting reinforcing ribs 1424 on the connecting surface 142, the strength of the connecting surface 142 can be improved, thereby improving the overall strength of the guide rail 140 and avoiding the problem of guide rail 140 deformation during the sliding connection between the drawer 150 and the guide rail 140.

[0146] Optionally, the reinforcing ribs 1424 include a plurality of ribs, which are spaced apart along the extension direction of the guide rail 140.

[0147] In some possible embodiments, see Figure 9 The guide groove 1411 is provided with an installation groove 1412 and a buffer pad. The installation groove 1412 is located on the groove wall of the guide groove 1411 away from the opening 111, and the buffer pad is located on the installation groove 1412. The buffer pad can abut against the drawer 150 when the drawer 150 is pushed into the storage cavity 131.

[0148] Therefore, by using a cushioning pad to abut against the drawer 150, on the one hand, it can prevent the drawer 150 from colliding with the side wall of the storage cavity 131 and making noise when it is pushed into the storage cavity 131, and on the other hand, it can protect the drawer 150, thereby improving the service life of the drawer 150.

[0149] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
