Description

Technical Field

[0001] This application relates to the technical field of anti-tipping, for example, to a box drawer assembly and a refrigerator-freezer. Background Art

[0002] Currently, the main structural feature of a drawer-type refrigerator-freezer is that it has multiple upper and lower drawer-type storage spaces. When in use, different items can be placed in different drawers. When retrieving an item, pull out the corresponding drawer, and the storage will be taken out with the drawer, making it convenient to pick up. For a drawer-type refrigerator-freezer, when the drawer is pulled out, the storage is taken out with the drawer, and the overall center of gravity of the refrigerator-freezer will move forward. If more drawers are pulled out, the overall center of gravity of the refrigerator-freezer will move forward more. When the center of gravity moves forward to a certain extent, the refrigerator-freezer has a risk of tipping forward. If only one drawer is pulled out, there is basically no risk.

[0003] In the related art, drawer-type refrigerator-freezers mostly adopt the method of adding counterweights on the back side to solve the problem of the risk of the refrigerator-freezer tipping forward.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, the counterweight increases the overall cost of the machine, and the volume occupied by the counterweight causes waste of space. In addition, the counterweight is relatively heavy, increasing the overall weight of the machine, which will lead to an increase in packaging and transportation costs. Moreover, the counterweight will affect the heat preservation effect of the refrigerator-freezer to a certain extent and increase the risk of condensation.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0007] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. This summary is not a general review, nor is it intended to identify key / important elements or delineate the protection scope of these embodiments, but rather serves as a preface to the subsequent detailed description.

[0008] The embodiments of the present disclosure provide a box drawer assembly and a refrigerator-freezer to avoid excessive forward movement of the center of gravity of the refrigerator-freezer and solve the risk of the refrigerator-freezer tipping forward.

[0009] An embodiment of the present disclosure provides a box drawer assembly. The box drawer assembly includes: a box defining a storage space; a drawer combination including a plurality of drawers. The drawers are slidably disposed in the storage space and are arranged side by side in the vertical direction. Each drawer is provided with a limiting portion. The limiting portion includes a communicating chute and a limiting groove. The limiting groove is located at the front end of the chute. The chute extends in the front-rear direction. The box is provided with a limiting cooperation portion adapted to the limiting portion, and each limiting portion is correspondingly disposed on one drawer. When one or more drawers in the drawer combination are opened, the corresponding limiting cooperation portions of the opened one or more drawers slide into the chute from the limiting groove, and the limiting portions of the other drawers in the drawer combination are in limiting cooperation with the limiting cooperation portions to limit the opening of the other drawers in the drawer combination.

[0010] Optionally, the box drawer assembly further includes: a guide rod portion disposed on the box. The guide rod portion includes a guide rod and guide posts. The guide rod extends in the arrangement direction of the plurality of drawers. The plurality of guide posts are spaced along the extension direction of the guide rod. The number of the guide posts is the same as and corresponds one by one to the number of the limiting portions. The limiting cooperation portion includes a guide post. When the guide posts corresponding to the opened one or more drawers are located in the chute, the guide rod is restricted from moving in the vertical direction, and the limiting grooves of the other drawers in the drawer combination are in limiting cooperation with their corresponding guide posts to limit the movement of the other drawers in the drawer combination in the front-rear direction.

[0011] Optionally, the limiting portion includes: an upper sliding member extending in the front-rear direction; a lower sliding member extending in the front-rear direction, spaced below the upper sliding member, and enclosing the chute with the upper sliding member. The chute extends in the front-rear direction. The front end face of the upper sliding member is configured with an inclined surface that slopes backward in the direction from top to bottom. The front end portion of the inclined surface protrudes from the front end face of the lower sliding member. The limiting groove includes the inclined surface and the front end face of the lower sliding member. When the drawer is closed, the guide post is located in front of the inclined surface or the front end face of the lower sliding member.

[0012] Optionally, when all the drawers corresponding to one guide rod are closed, the guide posts of one guide rod are all in the initial position. The initial position is in front of the inclined surface of the drawer corresponding to each guide post and above the limiting groove. When any one or more drawers are opened, the guide posts corresponding to any one or more drawers move downward along the inclined surface by a preset distance from the initial position and then move into the chute.

[0013] Optionally, the multiple drawers corresponding to a guide rod include a first drawer and a second drawer arranged in sequence from top to bottom. The first drawer is provided with a first sliding groove and a first inclined surface. The first drawer corresponds to the first guide post. When the first drawer is opened from the closed state, the first guide post moves downward along the first inclined surface by a first preset distance from its corresponding initial position and then enters the first sliding groove. The second drawer is provided with a second sliding groove and a second inclined surface. The second drawer corresponds to the second guide post. When the second drawer is opened from the closed state, the second guide post moves downward along the second inclined surface by a second preset distance from its corresponding initial position and then enters the second sliding groove. Wherein, the first preset distance is different from the second preset distance.

[0014] Optionally, the first drawer is provided with a first limiting portion, and the first limiting portion includes a first sliding groove and a first inclined surface. The second drawer is provided with a second limiting portion, and the second limiting portion includes a second sliding groove and a second inclined surface. The position and size of the first limiting portion relative to the first drawer are the same as the position and size of the second limiting portion relative to the second drawer. The first distance between the first guide post and the second guide post is the same as the second distance between the top wall of the first limiting portion and the top wall of the second limiting portion. Wherein, the height of the first inclined surface is different from the height of the second inclined surface, so that the first preset distance is different from the second preset distance.

[0015] Optionally, the drawers corresponding to a guide rod further include: a third drawer, arranged below the second drawer. The third drawer is provided with a third sliding groove and a third inclined surface. The third drawer corresponds to the third guide post. When the third drawer is opened from the closed state, the third guide post moves downward along the third inclined surface by a third preset distance from its corresponding initial position and then enters the third sliding groove. Wherein, the first preset distance is less than the second preset distance, and the second preset distance is less than the third preset distance.

[0016] Optionally, the inclination angles of the inclined surfaces of the multiple drawers corresponding to a guide rod are the same.

[0017] Optionally, the guide rod portion further includes: an elastic member, connected to the guide rod. When one or more drawers of the drawer combination are opened, the guide rod moves upward or downward, and the elastic member undergoes elastic deformation; and / or, the cabinet drawer assembly further includes: a horizontal guide rail, arranged on the drawer and located below the limiting portion; a horizontal guide groove, arranged on the cabinet body and intersecting with the guide rod portion. When the drawer is opened or closed, the horizontal guide rail can slide in the horizontal guide groove.

[0018] The embodiment of the present disclosure also provides a freezer, and the freezer includes the cabinet drawer assembly as described in any one of the above embodiments.

[0019] The cabinet drawer assembly and the freezer provided by the embodiment of the present disclosure can achieve the following technical effects:

[0020] The drawer activities are located within the storage space to facilitate the user in taking and placing items in and out of the drawer. Multiple drawers are arranged side by side, and each drawer is provided with a limiting part. The limiting part includes a limiting groove and a sliding groove. The box body is provided with a guide rod part, and the guide rod part can cooperate with the limiting part to restrict the drawer from being pulled open. When one or more drawers in the drawer combination are opened, the corresponding guide rod part and limiting part of this part of the drawers will not restrict the movement of this part of the drawers in the front-rear direction, and the limiting and cooperating part can slide within the sliding groove, and the sliding groove plays a guiding role to enable this part of the drawers to be pulled out and closed stably. While the guide rod parts of the other drawers within the drawer combination can cooperate with the limiting parts to restrict the other drawers from being pulled out. In this way, when the user pulls open the drawer, one or more drawers can be pulled open arbitrarily, while the other drawers cannot be pulled out after being limited. By restricting the number of drawers pulled open, this can avoid excessive forward movement of the center of gravity of the box body and prevent the box body from tipping forward. Moreover, the embodiment of the present disclosure can achieve the anti-tipping function by setting the limiting part and the guide rod part, without the need to transform the box body and the drawer itself. The structure is simple, the cost is low, and the impact on the overall weight is small. When applied to a freezer, it will not affect the performance of the freezer.

[0041] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0042] Combined Figures 1 to 10 As shown, the embodiments of the present disclosure provide a box drawer assembly. The box drawer assembly includes a box 10 and a drawer combination. The box 10 defines a storage space. The drawer combination includes a plurality of drawers 20. The drawers 20 are slidably arranged in the storage space, and the plurality of drawers 20 are arranged side by side in the vertical direction.

[0043] In the embodiments of the present disclosure, the drawer 20 is slidably disposed in the storage space, so as to facilitate taking and placing items from the drawer 20. The arrangement of multiple drawers 20 facilitates the classification of stored items, thereby improving the user experience. The multiple drawers 20 are arranged in the vertical direction, which can increase the size of the cabinet-drawer assembly in the height direction, reduce the size in the width direction, reduce the floor space occupied by the cabinet-drawer assembly, and increase the storage capacity of the cabinet-drawer assembly.

[0044] Optionally, as Figures 1 to 4 shown, the cabinet-drawer assembly further includes an anti-tipping device, and the anti-tipping device includes a matching limiting portion 201 and a limiting and cooperating portion 101. The limiting portion 201 is disposed on the drawer 20, and the limiting and cooperating portion 101 is disposed on the cabinet 10. Each limiting portion 201 is correspondingly disposed on one drawer 20. Wherein, when one or more drawers 20 in the drawer combination are opened, the corresponding limiting portions 201 of the other drawers 20 in the drawer combination are in limiting cooperation with the limiting and cooperating portion 101 to limit the opening of the other drawers 20 in the drawer combination.

[0045] In the embodiments of the present disclosure, the limiting portion 201 can cooperate with the limiting and cooperating portion 101 for limiting to restrict the drawer 20 from being pulled out. Each limiting portion 201 is correspondingly disposed on one drawer 20, that is to say, the number of drawers 20 is greater than or equal to the number of limiting portions 201. When the number of drawers 20 is the same as the number of limiting portions 201, the number of drawers 20 is the same as the number of limiting portions 201 and they correspond one by one. When the number of drawers 20 is greater than the number of limiting portions 201, some drawers 20 can be not provided with the limiting portion 201 according to requirements. By adopting the cabinet-drawer assembly of the embodiments of the present disclosure, when one or more drawers 20 need to be pulled out, the other drawers 20 in the drawer combination cannot be opened, which can limit the number of drawers 20 pulled out at the same time, avoid a plurality of drawers 20 being pulled out at the same time, avoid the center of gravity of the cabinet-drawer assembly from moving forward, and further avoid the cabinet 10 from tipping over.

[0046] In some alternative embodiments, when one drawer 20 in the drawer combination is opened, the other drawers 20 in the drawer combination are restricted from being pulled out.

[0047] In some other alternative embodiments, when multiple drawers 20 in the drawer combination are opened, the other drawers 20 in the drawer combination are restricted from being pulled out.

[0048] In actual use, the limiting portion 201 and the limiting and cooperating portion 101 can be set according to the number of drawers 20 in the drawer combination or the layout of the drawers 20, so that the number of drawers 20 that can be pulled out at the same time is within the number of drawers 20 that cause the drawer combination to tip forward.

[0049] Optionally, as Figures 2 to 4As shown in the figure, the limiting part 201 is arranged on the side of the drawer 20 facing the box body. The limiting part 201 includes a sliding groove 203 and a limiting groove 204. The front end of the sliding groove 203 is configured with the limiting groove 204, and the sliding groove 203 extends in the front-rear direction. When one or more drawers in the drawer combination are opened, the corresponding limiting and matching parts 101 of the opened one or more drawers enter the sliding groove 203 from the limiting groove 204 and slide therein, and the corresponding limiting parts 201 of the other drawers in the drawer combination are in limiting cooperation with the limiting and matching parts 101 to limit the opening of the other drawers in the drawer combination.

[0050] In the embodiment of the present disclosure, when one or more drawers in the drawer combination are opened, the corresponding guide rod parts and limiting parts of this part of the drawers do not limit the movement of this part of the drawers in the front-rear direction, and the limiting and matching parts can slide in the sliding groove. The sliding groove plays a guiding role to enable this part of the drawers to be stably pulled out and closed. And the guide rod parts and limiting parts of the other drawers in the drawer combination can cooperate to limit the pulling out of the other drawers. By limiting the number of drawers pulled out, the center of gravity of the box body can be prevented from moving forward too much, and the box body can be prevented from tipping forward.

[0051] Optionally, as Figures 2 to 4 shown, the box body drawer assembly further includes a guide rod part 102. The guide rod part 102 is arranged on the box body 10. The guide rod part 102 is arranged on the side wall of the box body 10 facing the drawer 20. The guide rod part 102 includes a guide rod 103 and a guide post 104. The guide rod 103 extends along the arrangement direction of the plurality of drawers 20; a plurality of guide posts 104 are arranged on the guide rod 103 at intervals along the extension direction of the guide rod 103. The number of the guide posts 104 is the same as and corresponds one by one to the number of the limiting parts. The limiting and matching part 101 includes the guide post 104; wherein, when the guide posts 104 corresponding to the opened one or more drawers 20 are located in the sliding groove 203, the guide rod 104 is restricted from moving in the vertical direction, and the limiting groove 204 of the other drawers 20 in the drawer combination is in limiting cooperation with the corresponding guide posts 104 thereof to limit the movement of the other drawers 20 in the drawer combination in the front-rear direction.

[0052] In the embodiment of the present disclosure, the number of the guide posts 104 is the same as and corresponds one by one to the number of the limiting parts. When the drawer 20 is opened and closed, the guide posts 104 can slide along the sliding groove 203. The guide posts 104 can also move from the sliding groove 203 to the limiting groove 204, or move from the limiting groove 204 to the position of the sliding groove 203. When the drawer 20 is opened, the guide posts 104 move from the limiting groove 204 to the inside of the sliding groove 203. In this way, the drawer corresponding to the guide post can slide in the front-rear direction. At the same time, the sliding groove plays a limiting role in the vertical direction of the guide rod, restricting the overall movement of the guide rod in the vertical direction. In this way, the guide posts on the guide rod that do not enter the sliding groove cannot move in the vertical direction and are restricted from moving in the front-rear direction by the limiting groove, so that the drawers corresponding to the guide posts that do not enter the sliding groove are locked and cannot be opened.

[0053] Optionally, the diameter of the guide post 104 is smaller than the dimension of the sliding groove 203 in the height direction, which facilitates the sliding of the guide post 104 in the sliding groove 203.

[0054] In actual use, the diameter of the guide post 104 is slightly smaller than the dimension of the sliding groove 203 in the height direction to avoid the situation that the diameter of the guide post 104 is too small, resulting in the guide post 104 falling off from the sliding groove 203 or the guide post 104 being fractured under force.

[0055] Optionally, the number of the guide rods 103 is one or more. When there is one guide rod 103, the guide rod 103 is provided with a plurality of guide posts 104, and the number of the guide posts 104 is the same as and corresponds to the number of the limiting parts 201 one by one.

[0056] Optionally, when the number of the drawers 20 is large, the corresponding number of the limiting parts 201 is also large. At this time, a plurality of guide rods 103 can be provided, and each guide rod 103 is correspondingly provided with a plurality of guide posts 104. The plurality of guide rods 103 are arranged in sequence in the vertical direction to reduce the force on the guide rods 103 and improve the service life and use stability of the guide rods 103.

[0057] Optionally, as Figure 3 shown, the limiting part 201 includes an upper sliding member 2021 and a lower sliding member 2023. The upper sliding member 2021 extends in the front-rear direction; the lower sliding member 2023 extends in the front-rear direction. The lower sliding member 2023 is spaced below the upper sliding member 2021 and encloses a sliding groove 203 with the upper sliding member 2021. The sliding groove 203 extends in the front-rear direction. Among them, the front end face of the upper sliding member 2021 is configured with an inclined surface 2022. Along the direction from top to bottom, the inclined surface 2022 inclines backward, and the front end of the inclined surface 2022 protrudes from the front end face of the lower sliding member 2023. The limiting groove 204 includes the inclined surface 2022 and the front end face of the lower sliding member 2023.

[0058] In the embodiment of the present disclosure, the upper sliding member 2021 and the lower sliding member 2023 enclose a sliding groove 203, and the sliding groove 203 extends in the front-rear direction so that the sliding groove 203 can move relative to the guide post 104 in the front-rear direction, thereby facilitating the opening or closing of the drawer 20. The front end face of the upper sliding member 2021 is configured with an inclined surface 2022, and the limiting groove 204 includes the inclined surface 2022 and the front end face of the lower sliding member 2023. In this way, the inclined surface 2022 and the front end face of the lower sliding member 2023 form a vertically extending limiting groove 204. After the guide post 104 moves from the sliding groove 203 to the limiting part 201, it can move in the vertical direction so that the guide post 104 cooperates with the inclined surface 2022 or the front end face of the lower sliding member 2023 for limiting, thereby realizing the limiting when the drawer 20 is closed.

[0059] Optionally, when the drawer 20 is closed, the guide post 104 is located in front of the inclined surface 2022 or the front end face of the lower sliding member 2023.

[0060] In an embodiment of the present disclosure, when the drawer 20 is closed, the guide post 104 is located in the limit groove 204 and in front of the inclined surface 2022 or the front end surface of the lower sliding member 2023. That is to say, when the drawer 20 is closed, the guide post 104 is located in the limit groove 204, and the guide post 104 can be in limit cooperation with the inclined surface 2022 or the front end surface of the lower sliding member 2023. The setting of the inclined surface 2022 also plays a guiding role. When the guide post 104 moves from the limit groove 204 to the sliding groove 203, the guide post 104 can also move along the inclined surface 2022 into the sliding groove 203.

[0061] Optionally, as Figure 10 shown, when the multiple drawers 20 corresponding to one guide rod 103 are all closed, the guide posts 104 of one guide rod 103 are all located at the initial position. The initial position is in front of the inclined surface 2022 of the drawer 20 corresponding to each guide post 104 and in the upper part of the limit groove 204. When any one or more drawers 20 are opened, the guide posts 104 corresponding to any one or more drawers 20 move downward along the inclined surface 2022 by a preset distance from the initial position and then move into the sliding groove 203.

[0062] In an embodiment of the present disclosure, one guide rod 103 is provided with multiple guide posts 104, and multiple guide posts 104 correspond to multiple drawers 20. When the multiple drawers 20 corresponding to one guide rod 103 are all closed, the guide posts 104 are all in the initial state, and the elastic member 105 does not undergo elastic deformation. That is to say, the multiple guide posts 104 are all in the upper part of the limit groove 204 of their corresponding drawers 20 and in front of the inclined surface 2022. In this way, the inclined surface 2022 can play a limiting role on the guide posts 104, and when any one or more drawers 20 are pulled out, the guide posts 104 corresponding to the pulled-out drawers 20 can move downward and towards the sliding groove 203 under the guiding action of the inclined surface 2022 and move into the sliding groove 203, so as to facilitate the opening and closing of the drawer 20.

[0063] It should be noted that: the preset distance in the embodiment of the present disclosure is not a fixed value, and the distance range that can enable the guide post 104 to enter the sliding groove 203 and slide in the sliding groove 203 belongs to the preset distance of this application.

[0064] Optionally, as Figure 6 shown, the multiple drawers 20 of the drawer combination are arranged in sequence along the vertical direction, the guide rod 103 extends along the vertical direction, the guide rod portion 102 further includes an elastic member 105, the elastic member 105 is connected to the guide rod 103. When one or more drawers 20 of the drawer combination are opened, the guide rod 103 moves upward or downward, and the elastic member 105 undergoes elastic deformation.

[0065] In an embodiment of the present disclosure, the guide rod 103 is connected to the elastic member 105. In this way, when one or more drawers 20 need to be opened, the guide rod 103 can move along the limit groove 204 from the initial state, so that the guide post 104 corresponding to the drawer 20 to be opened can correspond to the sliding groove 203. In this way, when the user applies a force to pull open the guide post 104 of the drawer 20 to be opened, it can move upward or downward in the limit groove 204 and move from the limit groove 204 into the sliding groove 203, thereby realizing the opening or closing of the drawer 20. At this time, the elastic member 105 undergoes elastic deformation. When all the drawers 20 of the drawer combination are closed, the elastic member 105 returns to its original state, so that all the guide posts 104 of the guide rod 103 are located in the limit groove 204 and the guide posts 104 of the guide rod 103 return to the initial position.

[0066] Optionally, as Figures 6 to 9 shown, the multiple drawers 20 corresponding to one guide rod 103 include a first drawer 205 and a second drawer 206 arranged in sequence from top to bottom. The first drawer 205 is provided with a first sliding groove 2053 and a first inclined surface 2051. The first drawer 205 corresponds to the first guide post 1041. When the first drawer 205 moves from closed to open, the first guide post 1041 moves downward a first preset distance along the first inclined surface 2051 from its corresponding initial position and then enters the first sliding groove 2053; the second drawer 206 is provided with a second sliding groove 2063 and a second inclined surface 2061. The second drawer 206 corresponds to the second guide post 1042. When the second drawer 206 moves from closed to open, the second guide post 1042 moves downward a second preset distance along the second inclined surface 2061 from its corresponding initial position and then enters the second sliding groove 2063; wherein, the first preset distance is different from the second preset distance.

[0067] In the embodiments of the present disclosure, the first preset distance is different from the second preset distance. Thus, when the first drawer 205 is opened, since the first guide post 1041 is located in front of the inclined surface 2022, the first guide post 1041 can only move downward along the inclined surface 2022. The first guide post 1041 moves downward along the first inclined surface 2051 by the first preset distance and moves into the first chute 2053. In this way, the first guide post 1041 of the first drawer 205 is disengaged from the first limit groove 204, and the first guide post 1041 can move relative to the first chute 2053 in the front-rear direction, so that the first drawer 205 can be pulled out or closed. At the same time, after the first guide post 1041 moves downward by the first preset distance, the entire guide rod 103 moves downward by the first preset distance, and the second guide post 1042 provided on the guide rod 103 also moves downward by the first preset distance. Since the first preset distance is different from the second preset distance, the second guide post 1042 still remains in the second limit groove 204, and the second guide post 1042 can be close to or abutted against the inclined surface 2022 or the front end surface of the lower sliding member 2023 to continue the limit, so that the second drawer 206 cannot be pulled out. In addition, when the first guide post 1041 slides into the first chute 2053, the first chute 2053 can limit the first guide post 1041 in the vertical direction and restrict the movement of the first guide post 1041 in the vertical direction. In this way, the guide rod 103 is also restricted from moving in the vertical direction, and the second guide post 1042 of the second drawer 206 will be fixed in the limit groove 204, which can lock the second drawer 206 and prevent the second drawer 206 from being pulled out. Similarly, when the second drawer 206 is pulled out, the first drawer 205 is also limited, and the principle is the same as the above and will not be elaborated here.

[0068] Optionally, the first drawer 205 is provided with a first limiting portion 2052. The first limiting portion 2052 includes a first chute 2053 and a first inclined surface 2051. The second drawer 206 is provided with a second limiting portion 2062. The second limiting portion 2062 includes a second chute 2063 and a second inclined surface 2061. The position and size of the first limiting portion 2052 relative to the first drawer 205 are the same as the position and size of the second limiting portion 2062 relative to the second drawer 206. The first distance between the first guide post 1041 and the second guide post 1042 is the same as the second distance between the top wall of the first limiting portion 2052 and the top wall of the second limiting portion 2062. Wherein, the height of the first inclined surface 2051 is different from the height of the second inclined surface 2061, so that the first preset distance is different from the second preset distance.

[0069] In the embodiments of the present disclosure, the position and size of the first limiting portion 2052 relative to the first drawer 205 are the same as those of the second limiting portion 2062 relative to the second drawer 206. It can be understood that: the distance between the lower wall surface of the first limiting portion 2052 and the bottom wall of the first drawer 205 is the same as the distance between the lower wall surface of the second limiting portion 2062 and the bottom wall of the second drawer 206, the distance between the front wall surface of the first limiting portion 2052 and the rear side wall of the first drawer 205 is the same as the distance between the front wall surface of the second limiting portion 2062 and the rear side wall of the second drawer 206, and the height of the first limiting portion 2052 is the same as the height of the second limiting portion 2062. The distance between the first guide post 1041 and the second guide post 1042 is the same as the distance between the top wall of the first limiting portion 2052 and the top wall of the second limiting portion 2062. It can be understood that: the distance between the first guide post 1041 and the second guide post 1042 is the same as the distance between the first drawer 205 and the second drawer 206. In this way, the guide rod 103 extends vertically and can cooperate with multiple limiting portions 201. The heights of the first inclined surface 2051 and the second inclined surface 2061 are different. Since the guide post 104 is in the initial position, the guide post 104 is in front of the inclined surface 2022 and above the limiting groove 204. Here, the heights of the first inclined surface 2051 and the second inclined surface 2061 are different, so that the distances from the initial position to the sliding groove 203 are different, so that the first preset distance and the second preset distance can be different. Furthermore, when one of the first drawer 205 and the second drawer 206 is pulled out, the other of the first drawer 205 and the second drawer 206 is restricted from being pulled out.

[0070] It should be noted that: the limiting portion 201 and the guide rod portion 102 in the embodiments of the present disclosure are not limited to the above two drawers 20, and the number of drawers 20 can also be greater than two drawers 20.

[0071] Optionally, when the number of drawers 20 corresponding to one guide rod 103 is greater than two drawers 20, the preset distances corresponding to at least two of the multiple drawers 20 are different. That is to say, the preset distances corresponding to other drawers 20 can be the same as the first preset distance or the second preset distance, or can be different from both the first preset distance and the second preset distance.

[0072] In a specific embodiment, when there are multiple drawers 20 corresponding to one guide rod 103, the preset distances corresponding to the multiple drawers 20 are all different, so that only one drawer 20 can be opened each time, and the guide posts 104 of the other drawers 20 are staggered from the sliding groove 203 to lock the other drawers 20.

[0073] In another specific embodiment, when there are multiple drawers 20 corresponding to a guide rod 103, the preset distances corresponding to at least two drawers 20 are the same. In this way, the drawers 20 with the same preset distance can be opened each time, increasing the number of opened drawers 20 and improving convenience. At the same time, it can also limit the number of drawers 20 opened simultaneously, preventing the center of gravity of the cabinet drawer assembly from moving forward due to excessive opening of the drawers 20, which may cause tipping.

[0074] Optionally, the drawers 20 corresponding to a guide rod 103 further include a third drawer 207, which is arranged below the second drawer 206. The third drawer 207 is provided with a third chute 2073 and a third inclined surface 2071. The third drawer 207 corresponds to a third guide post 1043. When the third drawer 207 moves from the closed state to the open state, the third guide post 1043 moves downward along the third inclined surface 2071 by a third preset distance from its corresponding initial position and then enters the chute 203. Among them, the first preset distance is less than the second preset distance, and the second preset distance is less than the third preset distance.

[0075] In the embodiments of the present disclosure, a plurality of drawers 20 can be correspondingly arranged for one guide rod 103. The first drawer 205, the second drawer 206, and the third drawer 207 are arranged in sequence from top to bottom, and the first preset distance is less than the second preset distance, and the second preset distance is less than the third preset distance. In this way, as Figure 6 and Figure 7 shown, when the first drawer 205 is pulled open, the first guide post 1041 moves downward along the first inclined surface 2051 by a first preset distance and enters the chute 203, and the guide rod 103 moves downward as a whole by the first preset distance. At this time, the moving distance of the second guide post 1042 is less than the second preset distance, and the moving distance of the third guide post 1043 is also less than the third preset distance. Therefore, neither the second guide post 1042 nor the third guide post 1043 moves to the position of the chute 203. That is to say, both the second guide post 1042 and the third guide post 1043 are higher than the highest point of the chute 203. At this time, the second guide post 1042 is still in front of the second inclined surface 2061, and the third guide post 1043 is still in front of the third inclined surface 2071. The second guide post 1042 and the third guide post 1043 are interfered and limited by their respective corresponding inclined surfaces 2022 and cannot be pulled out. At this time, only the first drawer 205 can be pulled out.

[0076] As Figure 8As shown, when the second drawer 206 is pulled out, the second guide post 1042 moves along the second inclined surface 2061 for a second preset distance and enters the second sliding groove 2063, and the whole guide rod 103 moves downward for the second preset distance. At this time, since the second preset distance is greater than the first preset distance, the first guide post 1041 moves downward and is located in front of the front wall surface of the first lower sliding member 2054 after passing over the first sliding groove 2053. In this way, the first lower sliding member 2054 and the first guide post 1041 are limited, restricting the first drawer 205 from being pulled open. At the same time, the third guide post 1043 moves downward for the second preset distance. Since the second preset distance is less than the third preset distance, the third guide post 1043 is still located in front of the third inclined surface 2071, and the third inclined surface 2071 restricts the third guide post 1043 from moving in the front-back direction, so as to restrict the third drawer 207 from being pulled open. In this way, when the second drawer 206 is opened, the first drawer 205 and the third drawer 207 are restricted from being pulled open.

[0077] As Figure 9 shown, when the third drawer 207 is opened, the third guide post 1043 moves downward along the third inclined surface 2071 for a third preset distance, and the whole guide rod 103 moves downward for the third preset distance. Since the third preset distance is greater than the first preset distance and the second preset distance, the first guide post 1041 can move downward to the front wall surface of the first limiting portion 2052, and the second guide post 1042 can move downward to the front wall surface of the second limiting portion 2062. In this way, the pulling open of the first drawer 205 and the second drawer 206 is restricted, and only the third drawer 207 can be pulled open.

[0078] Since the guide rod 103 is connected to the elastic member 105, when all the drawers 20 corresponding to one guide rod 103 are closed, the guide rod 103 can move under the action of the elastic member 105 so that all the guide posts 104 of the guide rod 103 return to their initial positions.

[0079] In practical applications, the magnitudes of the first preset distance, the second preset distance, and the third preset distance can also be set according to actual requirements. The priority of pulling out the drawers 20 can be controlled according to the different preset distances set for the multiple drawers 20.

[0080] Optionally, according to the usage frequency of the drawers 20 from high to low, the preset distances corresponding to the drawers 20 increase. The drawer 20 with the highest usage frequency has the highest priority, which is convenient for the drawers 20 to be opened and closed multiple times, while the movement distances of the guide posts 104 corresponding to the other drawers 20 are smaller, and there will be no accidental opening or jamming.

[0081] It should be noted that the guide posts include a first guide post, a second guide post, and a third guide post. The limiting parts include a first limiting part, a second limiting part, and a third limiting part. The inclined surfaces include a first inclined surface, a second inclined surface, and a third inclined surface. The lower sliding parts include a first lower sliding part, a second lower sliding part, and a third lower sliding part.

[0082] Optionally, the elastic member 105 is connected between the bottom of the guide rod 103 and the box body 10.

[0083] Optionally, the guide rod portion 102 further includes a guide housing 106. The guide housing 106 covers the outside of the guide rod 103, and one end of the guide housing 106 is connected to the box body 10, and the other end of the guide housing 106 is open, so that the guide post 104 protrudes from the guide housing 106 to cooperate with the limiting part 201.

[0084] In the embodiment of the present disclosure, the guide housing 106 can limit the movement directions of the guide rod 103 and the guide post 104, so that the guide rod 103 can move along the vertical direction and is restricted from moving along the horizontal direction. Thus, when the guide post 104 is in the initial position, under the action of the guide housing 106, the guide post 104 can be in contact with the inclined surface 2022, avoiding the deviation of the movement of the guide post 104 when the drawer 20 moves.

[0085] Optionally, when the guide post 104 is in the initial position, one end of the guide post 104 abuts against the guide housing 106, the other end of the guide post 104 abuts against the inclined surface 2022, and the guide post 104 cannot move upward. As Figure 10 shown, the inclined surface 2022 and the guide housing 106 form a triangular area, the triangular area is located above the limiting groove 204, and when the guide post 104 is in the initial position, the guide post 104 is located in the triangular area.

[0086] Optionally, the inclined angles of the inclined surfaces 2022 of the multiple drawers 20 corresponding to one guide rod 103 are the same.

[0087] In the embodiment of the present disclosure, the inclined angles of the inclined surfaces 2022 of the multiple drawers 20 corresponding to one guide rod 103 are the same, so that the guide rod 103 extends vertically, and each guide post 104 of the guide rod 103 can abut against the inclined surface 2022, facilitating the movement of the guide post 104 along the inclined surface 2022, and further making the opening or limiting and locking of the drawer 20 more stable.

[0088] Optionally, the box-drawer assembly further includes a horizontal guide rail 30 and a horizontal guide groove 301. The horizontal guide rail 30 is provided on the drawer 20 and is located below the limiting part 201; the horizontal guide groove 301 is provided on the box body 10 and intersects with the guide rod 103. When the drawer 20 is opened or closed, the horizontal guide rail 30 can slide in the horizontal guide groove 301.

[0089] In the embodiments of the present disclosure, the horizontal guide rail 30 is located below the sliding member 202. The horizontal guide rail 30 slides within the horizontal chute 203. The horizontal slide rail and the horizontal chute 203 cooperate to make the opening or closing of the drawer 20 more stable.

[0090] Optionally, the horizontal guide groove 301 is provided on the side of the guide rod portion facing the drawer, and the horizontal guide groove is connected to the guide housing. In this way, the guide rod does not affect the sliding of the horizontal guide groove and the horizontal guide rail.

[0091] Optionally, the horizontal guide groove is perpendicular to the guide rod portion.

[0092] The embodiments of the present disclosure further provide a refrigerator freezer, which includes the cabinet drawer assembly according to any one of the above embodiments.

[0093] The refrigerator freezer provided by the embodiments of the present disclosure includes the cabinet drawer assembly according to any one of the above embodiments, and thus has the beneficial effects of the cabinet drawer assembly according to any one of the above embodiments, which will not be elaborated here.
