Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a refrigerator. Background Technology

[0002] Refrigerators are a common household appliance. They use a refrigeration system to cool the refrigerator's interior, maintaining a low temperature environment and extending the shelf life of food and other items stored inside. To maximize space utilization, refrigerators typically have storage shelves on the inside of the door. Beverage bottles, beer bottles, sauce bottles, and other containers can be placed upright on these shelves. However, containers on these shelves are not very stable, especially when the door is opened or closed quickly, as they are prone to shaking, tipping over, or even falling and breaking. Utility Model Content

[0003] Therefore, it is necessary to provide a refrigerator that can improve the installation stability of the container, addressing the shortcomings of existing technologies.

[0004] This application provides a refrigerator, including:

[0005] The enclosure includes a refrigeration compartment;

[0006] A door, which is connected to the housing, is used to open or close the refrigeration compartment;

[0007] A storage rack, which is connected to the inside of the door;

[0008] A first limiting plate, connected to the storage rack, is provided with at least two first limiting portions, which are used to engage with the container for limiting positioning; and

[0009] The clamping assembly includes at least two clamping assemblies, all of which are connected to the storage rack. Each clamping assembly is correspondingly arranged with each of the first limiting portions. The clamping assembly is used to clamp and fix the container that is limited and cooperated with by the first limiting portion corresponding to it.

[0010] In one embodiment, the clamping assembly includes:

[0011] Elastic components; and

[0012] At least two clamping members are provided, all of which are connected to the storage rack. All of the clamping members are arranged at circumferential intervals along the first limiting portion. All of the clamping members cooperate with each other to clamp and fix the container. At least one of the clamping members is connected to the storage rack through the elastic member.

[0013] In one embodiment, there are at least two elastic elements, and each elastic element is connected to a corresponding clamping element.

[0014] The clamping assembly further includes:

[0015] A support member is connected to the storage rack and is disposed between the storage rack and the clamping member. The top of each clamping member is rotatably connected to the support member. Each clamping member is connected to the support member through a corresponding elastic member. The distance between the bottoms of each clamping member is smaller than the distance between the tops of each clamping member.

[0016] In one embodiment, the storage rack includes:

[0017] Base plate; and

[0018] A side plate is connected to the bottom plate; a first limiting plate is connected to the side plate and is spaced apart from the bottom plate; a clamping assembly is disposed between the first limiting plate and the side plate; the bottom of the support member is connected to the bottom plate, and the top of the support member is connected to the first limiting plate.

[0019] In one embodiment, at least two support members are provided, and each support member is correspondingly connected to each of the clamping members; the support member includes:

[0020] A first support plate, which is connected to the storage rack;

[0021] Two second support plates are connected to the first support plate, and the two second support plates are arranged at intervals relative to each other.

[0022] A connecting shaft is connected to the second support plate, and the top of the clamping member is rotatably connected to the connecting shaft;

[0023] And / or, the bottom of each of the clamping members is chamfered on the side near the central axis of the first limiting portion.

[0024] In one embodiment, the refrigerator further includes:

[0025] A second limiting plate is located above the first limiting plate. The second limiting plate has at least two second limiting portions, which are used to engage with the container for limiting its position. Each of the at least two second limiting portions corresponds one-to-one with each of the at least two first limiting portions.

[0026] A lifting adjustment component is provided, which is connected between the second limiting plate and the storage shelf, and is used to adjust the height of the second limiting plate.

[0027] In one embodiment, the height adjustment assembly includes:

[0028] A lifting housing, wherein the lifting housing is connected to a second limiting plate, the first limiting plate is provided with a clearance hole, the lifting housing is movably inserted into the clearance hole, and the lifting housing has a first height position and a second height position, the first height position being higher than the second height position; and

[0029] A locking mechanism is installed at the bottom of the lifting shell. When the lifting shell is at the first height position, the locking mechanism can lock or release the first limiting plate; when the lifting shell is at the second height position, the second limiting plate overlaps the first limiting plate.

[0030] In one embodiment, the lifting adjustment assembly further includes:

[0031] A limiting component is provided, which is connected to the bottom of the lifting shell and engages with the first limiting plate for limiting.

[0032] In one embodiment, the lifting shell includes a first sidewall and a second sidewall arranged at an angle. The first sidewall has a first through hole, and the second sidewall has a second through hole. The second through hole is a rectangular hole, an oblong hole, or a strip-shaped hole. The locking mechanism includes a locking member and a toggle member. The locking member is movably inserted into the first through hole, and the toggle member is connected to the locking member. The toggle member is movably inserted into the second through hole and can move along the length direction of the second through hole to drive the locking member to extend outward through the first through hole to lock the first limiting plate or to retract and release the first limiting plate.

[0033] In one embodiment, the refrigerator further includes a first latching member and a plurality of second latching members. The first latching member is disposed on the storage shelf, and the plurality of second latching members are sequentially and spaced apart along the height direction of the door body. The first latching member is latched and connected to one of the second latching members.

[0034] The refrigerator described above has at least two first limiting parts on the first limiting plate and at least two clamping components, with each clamping component corresponding to each first limiting part. Therefore, when at least two containers are installed on the storage rack, on the one hand, each first limiting part can limit each container accordingly, and on the other hand, each clamping component can clamp and fix the container that is limited and matched by the first limiting part corresponding to it. This enables each container to be clamped and fixed, and each container to be independent of each other. Even if the outer diameter of the cross-sectional contour of the containers is different, the installation stability on the storage rack is still high and it is not easy to shake or fall off.

Detailed Implementation

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] As described in the background section, the related technologies suffer from poor stability when containers are installed on storage shelves. This is because there are almost no fixing devices on the inside of the door to secure the containers; they rely solely on the shape of the storage shelf itself for stability. This results in poor stability. While some related technologies propose installing a movable fixing plate on the storage shelf, connected to it via an elastic element, this method involves pressing the container down after it's placed on the shelf. However, taking a circular axial cross-sectional profile as an example, when the outer diameter of the containers' axial cross-sections varies, the fixing plate can effectively press down containers with larger outer diameters, but it cannot press down containers with smaller outer diameters. Containers with smaller outer diameters exhibit poor stability and still face the risk of wobbling, tipping over, or even falling and breaking.

[0049] For the reasons mentioned above, this application provides a refrigerator that can improve the installation stability of containers.

[0050] refer to Figure 1 The refrigerator 10 of this embodiment includes a cabinet 11 and a door 12. The cabinet 11 has a cooling compartment. The door 12 is connected to the cabinet 11, and the door 12 can open or close the cooling compartment, for example, by rotating relative to the cabinet 11.

[0051] The refrigerator body 11 includes an inner liner, an outer shell, and a first insulation layer. The inner liner forms a cooling compartment. The cooling compartment is used to store food and other items. The cooling compartment may have an access opening, allowing users to put or take items into or out of the cooling compartment. The outer shell may be attached to the outside of the inner liner to form the appearance of the refrigerator 10. The first insulation layer may be filled between the inner liner and the outer shell to prevent heat transfer between the cooling compartment and the external space of the refrigerator body 11. Optionally, the first insulation layer may be made of various insulation materials, including but not limited to polyurethane or insulating cotton.

[0052] The number of refrigeration compartments is not limited to one; it can be, for example, multiple. When there are multiple refrigeration compartments, there are multiple inner liner compartments, each corresponding to a specific refrigeration compartment. Specifically, the multiple refrigeration compartments may include refrigerator compartments and freezer compartments. The internal temperature of the refrigerator compartment is maintained, for example, between 0°C and 5°C, for storing items in refrigeration mode. The internal temperature of the freezer compartment is maintained, for example, between -30°C and 0°C, for storing items in freezing mode. In addition, the multiple refrigeration compartments may also include other chambers, such as vacuum chambers, variable temperature chambers, etc., which will not be described in detail in this embodiment.

[0053] The refrigerator compartment and the freezer compartment can be arranged along the width direction of the refrigerator 10, along the height direction of the refrigerator 10, or in other ways, without limitation. When the refrigerator compartment and the freezer compartment are arranged along the width direction of the refrigerator 10, for example, the refrigerator compartment can be located to the right of the freezer compartment; when the refrigerator compartment and the freezer compartment are arranged along the height direction of the refrigerator 10, for example, the refrigerator compartment can be located above the freezer compartment.

[0054] The door 12 includes a shell, a cover, and a second insulation layer. When the door 12 is closed, the cover faces the cooling compartment and closes the access opening of the cooling compartment. The shell may be attached to the side of the cover facing away from the cooling compartment to form the appearance of the refrigerator 10. The second insulation layer may be filled between the shell and the cover to block heat transfer between the cooling compartment and the external space of the door 12 when the door 12 is closed. Optionally, the second insulation layer may be made of various insulation materials, including but not limited to polyurethane or insulating cotton.

[0055] For example, door 12 is connected to cabinet 11 via a hinge assembly (not shown in the figures), allowing door 12 to rotate relative to cabinet 11, thereby opening or closing the access port of the refrigeration compartment. When door 12 is open, a user can insert or remove items through the access port. When door 12 is closed, items can be placed inside the refrigeration compartment for low-temperature storage.

[0056] The number of doors 12 corresponds to the number of refrigeration rooms. For example... Figure 1As shown, the refrigerator body 11 has two cooling compartments, which can be arranged along the width of the refrigerator 10. The cooling compartment located on the left side of the refrigerator 10, for example, is a freezer compartment, and can have either one or two doors 12. When the cooling compartment on the left side of the refrigerator 10 has one door 12, it is called a single-door refrigerator 10; when the cooling compartment on the left side of the refrigerator 10 has two doors 12, it is called a double-door refrigerator 10. The two doors 12 can be rotatably connected to opposite sides of the refrigerator body 11 in the horizontal direction. The two doors 12 can rotate in opposite directions relative to the refrigerator body 11 to open or close the upper cooling compartment.

[0057] For example, the cooling compartment located on the right side of the refrigerator 10 may be configured as a refrigerator compartment, which can be either a single-door or double-door configuration, without limitation. Below the refrigerator compartment, for example, two drawers may be provided. These two drawers can be vertically positioned within the cooling compartment below the refrigerator 10. The two drawers can be slidably connected to the refrigerator body 11 on opposite sides in the horizontal direction via guide rails. The two drawers can slide relative to the refrigerator body 11. Users can pull the drawers out of the cooling compartment to place or remove items from the drawers. Users can also push the drawers into the cooling compartment to preserve the items inside at a low temperature.

[0058] See Figure 2 , Figure 2This is a schematic diagram of the refrigeration system in the refrigerator 10 provided in this embodiment of the present disclosure. The refrigeration system is used to provide cooling capacity to the refrigeration compartment. Optionally, the refrigeration system includes a compressor 101, an evaporator 102, a dryer filter (not shown in the figure), a capillary tube 103, a condenser 104, and a gas-liquid separator (not shown in the figure). The working process of the refrigeration system includes a compression process, a condensation process, a throttling process, and an evaporation process. The compression process is as follows: when the power cord of the refrigerator 10 is plugged in and the contacts of the thermostat are closed, the compressor 101 starts to work. Low-temperature, low-pressure refrigerant is drawn into the compressor 101 and compressed into high-temperature, high-pressure superheated gas in the cylinder of the compressor 101 before being discharged into the condenser 104. The condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser 104, and the temperature continuously decreases, gradually being cooled into room-temperature, high-pressure saturated vapor, and further cooled into saturated liquid. The temperature no longer decreases; this temperature is called the condensation temperature. The pressure of the refrigerant remains almost constant throughout the condensation process. The throttling process is as follows: After condensation, the saturated liquid refrigerant flows into capillary tube 103 after being filtered to remove moisture and impurities through a dryer filter. There, it undergoes throttling and pressure reduction, transforming the refrigerant into a room-temperature, low-pressure wet vapor. The evaporation process involves the room-temperature, low-pressure wet vapor absorbing heat and vaporizing within the evaporator 102. This not only lowers the temperature of the evaporator 102 and its surroundings but also transforms the refrigerant into a low-temperature, low-pressure gas. The refrigerant exiting the evaporator 102 passes through a gas-liquid separator and returns to the compressor 101. This process is repeated, transferring heat from the refrigerator 10's cooling compartment to the outside air of the cabinet 11, thus achieving the purpose of refrigeration.

[0059] The refrigeration system also includes air ducts and fans. The refrigeration compartment has air outlets and return air inlets, both of which are connected to the air ducts, creating a circulating flow path between the air ducts and the refrigeration compartment. The evaporator 102 and the fan are both located within the air ducts. The fan provides power, allowing the airflow inside the refrigeration compartment to enter the air duct through the return air inlet. As the airflow passes through the evaporator 102, it exchanges heat with the evaporator 102, thus reducing the airflow temperature. The cooled airflow then enters the interior of the refrigeration compartment through the air outlet.

[0060] For example, the air outlet is located on the top wall and / or rear wall of the inner liner. The rear wall of the inner liner refers to the side wall of the inner liner facing the access port. When the air outlet is located on the top wall of the inner liner, cold air enters the inner liner from the top downwards, which can improve the uniformity of airflow inside the refrigeration room; when the air outlet is located on the rear wall of the inner liner, specifically in the middle or upper part of the rear wall, this helps to improve the uniformity of cold air inside the refrigeration room.

[0061] The return air vent can be located on the top wall of the inner liner, the side wall of the inner liner, or the bottom wall of the inner liner. The specific location can be flexibly adjusted and set according to actual needs, and there are no restrictions here.

[0062] Optionally, the number of air outlets and return air outlets can be set independently, including but not limited to one or more. The specific number can be flexibly adjusted and set according to actual needs, and there is no limitation here.

[0063] The refrigerator 10 in this embodiment also includes shelves. The shelves are located inside the refrigeration compartment, specifically, for example, inside the refrigerator compartment. The shelves can be used to place various items such as beverages or food.

[0064] The shelf unit is connected to the inner liner. Specifically, the left and right opposite sides of the shelf unit are connected to the left and right opposite sides of the inner liner's inner wall, thus providing stable support for the shelf unit. Optionally, mounting portions are provided on both the left and right opposite sides of the inner liner's inner wall. These mounting portions can be integrally formed onto the inner liner's inner wall using vacuum forming or by adhesive bonding. The left and right opposite sides of the shelf unit are respectively mounted on these mounting portions. For example, the mounting portions may have slots, allowing the shelf unit to be detachably mounted to them via a plug-in connection. When the shelf unit is inserted into the mounting portion, it may also be secured to the mounting portion using a snap-fit ​​mechanism, preventing the shelf unit from being easily pulled out of the inner liner and improving the stability of the shelf unit's installation on the inner liner.

[0065] See Figures 3 to 7 For example, the refrigerator 10 also includes a storage shelf 13. The storage shelf 13 is connected to the inside of the door 12. The inside of the door 12 refers to the side of the door 12 closest to the cooling compartment when the door 12 is closed; the outside of the door 12 refers to the other side of the door 12. The door 12 supports the storage shelf 13, which can be opened or closed as the door 12 rotates. When the door 12 opens the cooling compartment by moving the storage shelf 13, containers can be placed or removed from the storage shelf 13.

[0066] For example, the refrigerator 10 also includes a first limiting plate 14. The first limiting plate 14 is connected to the storage shelf 13. Optionally, the first limiting plate 14 may be disposed at the top of the storage shelf 13, for example. Of course, the first limiting portion 141 may also be disposed at other parts of the storage shelf 13. The first limiting plate 14 has at least two first limiting portions 141, which are used to limit and cooperate with the container. For example, the first limiting portion 141 may include, but is not limited to, a limiting hole, a limiting recess, or two opposing limiting strips, etc., which can be flexibly adjusted and set according to actual needs, as long as they can limit the container.

[0067] Please see Figures 7 to 9For example, the refrigerator 10 also includes clamping components 15. There are at least two clamping components 15. Optionally, the number of first limiting portions 141 is including, but is not limited to, two, three, four, six, or other various quantities. The number of clamping components 15 is the same as the number of first limiting portions 141, and will not be described further here.

[0068] All clamping components 15 are connected to the storage rack 13. Each clamping component 15 is correspondingly set with each first limiting part 141. The clamping component 15 is used to clamp and fix the container that is limited and cooperated with by the first limiting part 141 corresponding to it.

[0069] The refrigerator 10 described above has at least two first limiting parts 141 on the first limiting plate 14 and at least two clamping components 15. Each clamping component 15 is correspondingly arranged with each first limiting part 141. Therefore, when at least two containers are installed on the storage rack 13, on the one hand, each first limiting part 141 can correspondingly limit each container, and on the other hand, each clamping component 15 can also clamp and fix the container that is limited and cooperated with by the first limiting part 141 corresponding to it. Thus, each container can be clamped and fixed, and each container is independent of each other. Even if the outer diameter of the cross-sectional contour of the container is different, the installation stability on the storage rack 13 is still high and it is not easy to shake or fall off.

[0070] Optionally, the clamping assembly 15 is located below the first limiting plate 14. The first limiting plate 14, for example, limits the lower half of the container, and the clamping assembly 15 is used to clamp and fix the bottom of the container. In this way, the container can be securely placed on the storage shelf 13.

[0071] To clamp and secure the container, the clamping assembly 15, for example, includes an elastic element 151, which may include, but is not limited to, a spring or elastic strip. The clamping assembly 15 also includes at least two clamping members 152. All clamping members 152 are connected to the storage rack 13, and are arranged circumferentially at intervals along the first limiting portion 141. All clamping members 152 cooperate with each other to clamp and secure the container. At least one clamping member 152 is connected to the storage rack 13 via the elastic element 151. When a container is inserted into the storage rack 13 through the first limiting portion 141, the bottom of the container presses against the clamping member 152, causing the clamping member 152 to elastically deform, thus clamping and securing the container.

[0072] Specifically, the elastic element 151 is not limited to one, but is provided as at least two, and each elastic element 151 is connected to a corresponding clamping element 152. In this way, during the installation process, the bottom of the container presses against each clamping element 152, and each clamping element 152 simultaneously presses against the corresponding elastic element 151, so that the container is securely mounted on the storage rack 13.

[0073] Optionally, the clamping component 152 may include, but is not limited to, a clamping arm, a clamping block, a clamping plate, a clamping piece, or a clamping rod, etc. The specific components can be flexibly adjusted and set according to actual needs, as long as they can be used to clamp and fix containers.

[0074] To facilitate the installation of the clamping member 152 on the storage rack 13, the clamping member 152 is connected to the storage rack 13 indirectly, for example. Of course, the clamping member 152 can also be directly connected to the storage rack 13; this is not limited here. For example, the clamping assembly 15 also includes a support member 153. The support member 153 is connected to the storage rack 13. The support member 153 includes, but is not limited to, a support plate, which can be a U-shaped plate or a flat plate, etc. The support member 153 is disposed between the storage rack 13 and the clamping member 152. That is, the clamping member 152 is connected to the storage rack 13 through the support member 153. Specifically, the top of each clamping member 152 is rotatably connected to the support member 153, and each clamping member 152 is connected to the support member 153 through a corresponding elastic member 151. The distance between the bottoms of each clamping member 152 is less than the distance between the tops of each clamping member 152. That is, the distance between the tops of each clamping member 152 is relatively large, so that the container can be easily inserted; the distance between the bottoms of each clamping member 152 is relatively small, and they work together to clamp and fix the bottom of the container, preventing the container from shifting or falling off.

[0075] Please see Figures 5 to 7 For example, the storage rack 13 includes a base plate 131 and side plates 132. The side plates 132 are connected to the base plate 131. A first limiting plate 14 is connected to the side plates 132, and the first limiting plate 14 is spaced apart from the base plate 131. A clamping assembly 15 is disposed between the first limiting plate 14 and the side plates 132. Specifically, the bottom of the support member 153 is connected to the base plate 131, and the top of the support member 153 is connected to the first limiting plate 14. In this way, the container is limited by the first limiting part 141, clamped and fixed by each clamping member 152, and supported by the base plate 131, resulting in high stability.

[0076] Optionally, at least two support members 153 are provided, with each support member 153 corresponding to each clamping member 152.

[0077] For example, the support member 153 includes a first support plate 1531. The first support plate 1531 is connected to the storage shelf 13.

[0078] For example, the support member 153 also includes two second support plates 1532. The two second support plates 1532 are connected to the first support plate 1531 and are arranged at intervals relative to each other.

[0079] Please see Figures 7 to 9For example, the support member 153 further includes a connecting shaft 1533. The connecting shaft 1533 is connected to the second support plate 1532. Specifically, the opposite ends of the connecting shaft 1533 are respectively connected to the two second support plates 1532. The top of the clamping member 152 is rotatably connected to the connecting shaft 1533. Optionally, the top of the clamping member 152 is provided with a shaft hole 1521, through which the clamping member 152 is rotatably sleeved on the connecting shaft 1533.

[0080] Please see Figure 7 and Figure 9 For example, each clamping member 152 has a chamfer 1522 on the side of its bottom closest to the central axis of the first limiting part 141. When the container is placed in the storage rack 13, the bottom of the container abuts against the chamfer 1522, driving each clamping member 152 to rotate in opposite directions, and clamping it with the elastic force of the elastic member 151 to fix the bottom of the container.

[0081] Please see Figures 5 to 7 For example, the refrigerator 10 also includes a second limiting plate 16. The second limiting plate 16 is located above the first limiting plate 14, and the second limiting plate 16 has at least two second limiting portions 161, which are used to limit the container. Optionally, the second limiting portions 161 may include, but are not limited to, limiting holes, limiting recesses, or two oppositely arranged limiting strips, etc., which can be flexibly adjusted and set according to actual needs, as long as they can limit the container. At least two second limiting portions 161 are provided in a one-to-one correspondence with at least two first limiting portions 141. Specifically, for example, four first limiting portions 141 are provided, and four second limiting portions 161 are provided accordingly. This facilitates the container to pass through the second limiting portions 161 and the first limiting portions 141 sequentially from top to bottom.

[0082] Please see Figures 6 to 10 For example, the refrigerator 10 also includes a lifting adjustment assembly 17. The lifting adjustment assembly 17 is connected between the second limiting plate 16 and the storage shelf 13, and is used to adjust the height position of the second limiting plate 16.

[0083] In use, for taller containers, the second limiting plate 16 can be raised using the lifting adjustment assembly 17, increasing its height. While the first limiting part 141 limits the container and the clamping assembly 15 clamps the bottom, the second limiting part 161 also limits the upper part of the container, restricting vertical swaying or tipping. This combination of upper and lower limiting positions secures the container within the storage rack 13, significantly reducing the risk of tipping even during frequent opening and closing of the storage rack 13 with the door 12. For shorter containers, the second limiting plate 16 can be lowered using the lifting adjustment assembly 17, allowing it to rest against the first limiting plate 14. The first limiting part 141 and the clamping assembly 15 then ensure stable installation of the container on the storage rack 13. Furthermore, this avoids the second limiting plate 16 occupying excessive space inside the refrigerator 10 when raised, thus improving space utilization and facilitating container access.

[0084] Please see Figure 7 , 8 and Figure 10 Based on the aforementioned embodiments, the lifting adjustment assembly 17 includes a lifting housing 171. The lifting housing 171 is connected to the second limiting plate 16. The first limiting plate 14 is provided with a clearance hole 142, and the lifting housing 171 is movably inserted into the clearance hole 142. The lifting housing 171 has a first height position and a second height position, with the first height position being higher than the second height position. The first height position is, for example, the extreme upward position of the lifting housing 171, i.e., the position where the second limiting plate 16 moves furthest from the first limiting plate 14; the second height position is, for example, the extreme downward position of the lifting housing 171, where the second limiting plate 16 overlaps the first limiting plate 14. The lifting adjustment assembly 17 also includes a locking mechanism 172. The locking mechanism 172 is installed at the bottom of the lifting housing 171. When the lifting housing 171 rises and moves to the first height position, the locking mechanism 172 can lock the first limiting plate 14, thereby fixing the second limiting plate 16 relative to the storage shelf 13. Of course, the locking mechanism 172 can also release the first limiting plate 14. After the first limiting plate 14 is released, the lifting adjustment component 17 lowers the height position of the second limiting plate 16 accordingly. Specifically, when the lifting shell 171 is at the second height position, the second limiting plate 16 overlaps the first limiting plate 14.

[0085] For example, there are two lifting housings 171 and two clearance holes 142. The two lifting housings 171 and the two clearance holes 142 are provided in a one-to-one correspondence. The two clearance holes 142 are provided, for example, on opposite sides of the first limiting plate 14.

[0086] Please see Figures 6 to 10Optionally, the clearance hole 142 may be, but is not limited to, a T-shaped hole, a rectangular hole, a circular hole or other shapes, and is not limited here. It can be adapted and set according to the shape of the lifting shell 171.

[0087] Please see Figure 7 , Figure 8 and Figure 10 Based on the aforementioned embodiments, the lifting adjustment assembly 17 further includes a limiting member 173. The limiting member 173 includes, but is not limited to, a limiting plate, a limiting block, or a limiting rod. The limiting member 173 is connected to the bottom of the lifting housing 171, and the limiting member 173 engages with the first limiting plate 14 in a vertically limiting manner. Thus, when the lifting housing 171 rises and moves to the first height position, the limiting member 173 abuts against the first limiting plate 14, preventing the lifting housing 171 from continuing to move upward and detaching from the storage rack 13. Furthermore, the locking mechanism 172 can lock the first limiting plate 14, thus fixing the lifting housing 171 and the second limiting plate 16 relative to the storage rack 13.

[0088] The length of the limiting member 173 is greater than the opening size of the clearance hole 142, which helps to prevent the limiting member 173 from passing through the clearance hole 142, thereby preventing the lifting shell 171 and the locking mechanism 172 from detaching upward from the storage shelf 13.

[0089] Please see Figure 7 , Figure 8 and Figure 10 For example, the lifting housing 171 includes a first sidewall 1711 and a second sidewall 1712 arranged at an angle. The first sidewall 1711 has a first through hole 1713, and the second sidewall 1712 has a second through hole 1714. The second through hole 1714 includes, but is not limited to, a rectangular hole, an oblong hole, or a strip hole. Specifically, the locking mechanism 172 includes a locking member 1721 and an actuating member 1722. The locking member 1721 is movably inserted into the first through hole 1713. The locking member 1721 includes, but is not limited to, a snap-fit ​​member or a connecting rod. The actuating member 1722 is connected to the locking member 1721, and the actuating member 1722 is movably inserted into the second through hole 1714 and can move along the length direction of the second through hole 1714. When the actuating member 1722 moves forward along the length direction of the second through hole 1714, the actuating member 1722 correspondingly drives the locking member 1721 to move, so that the locking member 1721 extends outward through the first through hole 1713 to lock the first limiting plate 14, thereby fixing the lifting shell 171 and the second limiting plate 16 to the storage rack 13; or, when the actuating member 1722 moves in the reverse direction along the length direction of the second through hole 1714, it can also retract and release the first limiting plate 14, so that the lifting shell 171 and the second limiting plate 16 can move downward to the second height position.

[0090] Optionally, two first sidewalls 1711 are provided, with the two first sidewalls 1711 arranged at intervals relative to each other, and a second sidewall 1712 connected between the two first sidewalls 1711. Each of the two first sidewalls 1711 is provided with a first through hole 1713, and the second sidewall 1712 is provided with one or two second through holes 1714. Two locking members 1721 and two actuating members 1722 are each provided, with the two locking members 1721 and the two actuating members 1722 connected in a one-to-one correspondence. Each locking member 1721 passes through each of the first through holes 1713, and each actuating member 1722 passes through each of the second through holes 1714.

[0091] For example, the refrigerator 10 also includes a first latching member 18 and a plurality of second latching members 19. Optionally, the first latching member 18 may be configured as a latching slot or a latching hole, and the second latching members 19 may be configured as a latching block adapted to the latching slot or a latching buckle that engages with the latching hole. Of course, the first latching member 18 may also be configured as a latching block or a latch, and the second latching members 19 may be configured as a latching slot or a latching hole accordingly.

[0092] For example, a first latching member 18 is disposed on the storage shelf 13, and a plurality of second latching members 19 are sequentially and spaced apart along the height direction of the door body 12. The first latching member 18 is latched and connected to one of the second latching members 19. The height direction of the door body 12 is as follows: Figure 1 The up and down directions in the middle.

[0093] Specifically, each of the opposite sides of the storage rack 13 is connected to a first latching member 18. Each of the opposite sides of the door 12 is provided with multiple second latching members 19. A first latching member 18 on one side of the storage rack 13 is latched to one of the second latching members 19 on one side of the door 12, and a first latching member 18 on the other side is latched to one of the second latching members 19 on the other side of the door 12. Therefore, by adjusting the installation position of the storage rack 13 in the height direction of the door 12, that is, by selecting a suitable height position for the second latching member 19 to connect with the first latching member 18, the height of the storage rack 13 on the door 12 can be adjusted.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0095] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
