Description

Technical Field

[0001] This utility model belongs to the field of refrigerator technology, specifically providing a drawer assembly and a refrigerator having the same assembly. Background Technology

[0002] Some existing refrigerators include a cabinet, doors, and drawers. The cabinet defines a storage compartment for holding food, and the door conceals this compartment. The cabinet also defines drawer space for installing drawers to hold food. Some refrigerators also have doors for the drawers, allowing the drawers to be hidden or revealed by opening and closing the doors. Other refrigerators have drawers that are directly exposed for easy and quick opening and closing by the user.

[0003] However, existing drawers typically offer a continuous, undivided space, making it impossible for users to organize and store food in separate sections. Furthermore, users must open the entire drawer each time they need to retrieve food, resulting in significant cold air loss from the refrigerator. Utility Model Content

[0004] One objective of this invention is to solve the problem that existing refrigerator drawers do not have partitioning functionality.

[0005] To achieve the above objectives, the present invention provides a drawer assembly in a first aspect, suitable for a refrigerator, comprising:

[0038] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0039] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the corresponding device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

A target object absorbs "coldness" while releasing "heat," and releases "coldness" while absorbing "heat." A target object retains "coldness" or "heat" to maintain its current temperature. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon; that is, a target object (e.g., evaporator) absorbs heat while refrigerating.

[0042] like Figure 1 As shown, the present invention provides a drawer assembly 100 and a refrigerator 001 having therewith, that is, the refrigerator 001 of the present invention includes the drawer assembly 100.

[0043] like Figure 1 As shown, in this utility model, the refrigerator 001 also includes a cabinet 200, a door 300, and a conventional drawer 400. The door 300 is rotatably mounted on the cabinet 200, and the drawer assembly 100 and the conventional drawer 400 are respectively mounted on the cabinet 200 by pulling out.

[0044] The standard drawer 400 is the type of drawer found in ordinary refrigerators and does not have two drawers that can be pulled out from each other. Since the standard drawer 400 is well known to those skilled in the art, it will not be described in detail here.

[0045] In addition, those skilled in the art can adjust the relative positions of the door 300, the drawer assembly 100 and the conventional drawer 400 as needed, for example, by placing the conventional drawer 400 between the door 300 and the drawer assembly 100.

[0046] It should be noted that, although Figure 1 The drawer assembly 100 shown is exposed and can be directly observed by the user, but those skilled in the art can also configure a door 300 to cover the drawer assembly 100 of this utility model as needed.

[0047] It should also be noted that this utility model Figure 1 The refrigerator 001 shown is intended to help those skilled in the art understand the technical solution of this utility model, and is not intended to limit the refrigerator 001 of this utility model to only one form. For example, the refrigerator 001 of this utility model can also be a side-by-side refrigerator, a refrigerator 001 with only one drawer with drawer assembly 100, a refrigerator 001 with a door 300 that covers the drawer assembly 100, and so on.

[0048] The following reference Figure 2 Examples of other forms of refrigerators 001 in this utility model will be given for illustration.

[0049] like Figure 2 As shown, for ease of understanding, the door 300 has been omitted in the example shown. Figure 2 The refrigerator 001 shown is a side-by-side refrigerator. The bottom of refrigerator 001 has a left-side storage space and a right-side storage space, and each of the left-side and right-side storage spaces has three drawer assemblies 100. The top storage space of refrigerator 001 also has a drawer assembly 100. When the door 300 of refrigerator 001 ( Figure 2 When the refrigerator 001 (not shown) is closed, each storage space of the refrigerator 001 and the drawer assembly 100 arranged in the storage space are covered by the door 300.

[0050] The following reference Figures 3 to 9 The drawer assembly 100 of this utility model will be described in detail below.

[0051] like Figures 3 to 9As shown, in some embodiments illustrated, the drawer assembly 100 includes a mother drawer 110 and a child drawer 120. The mother drawer 110 is used to connect to the housing 200 to mount the drawer assembly 100 onto the housing 200. The child drawer 120 is mounted to the mother drawer 110 in a pull-out manner so that a user can open the child drawer 120 independently.

[0052] like Figure 6 and Figure 7 As shown, for ease of description, in some embodiments of this utility model, the front panel of the mother drawer 110 is referred to as the first front panel 111, the left and right side panels of the mother drawer 110 are respectively referred to as the first side panels 112, the rear side panel of the mother drawer 110 is referred to as the first rear side panel 113, and the bottom side panel of the mother drawer 110 is referred to as the first bottom panel 114. The front panel of the child drawer 120 is referred to as the second front panel 121, the left and right side panels of the child drawer 120 are respectively referred to as the second side panels 122, the rear side panel of the child drawer 120 is referred to as the second rear side panel 123, and the bottom side panel of the child drawer 120 is referred to as the second bottom panel 124.

[0053] like Figure 6 and Figure 7 As shown, in some embodiments of this utility model, a mounting opening 1111 is provided on one side of the first front panel 111 in the left-right direction, and the sub-drawer 120 passes through the mounting opening 1111 and is installed on the mother drawer 110 in a pull-out manner relative to the mother drawer 110.

[0054] Furthermore, in some embodiments of this utility model, the mounting port 1111 may be located on the left side of the first front panel 111.

[0055] Those skilled in the art will understand that by configuring the drawer assembly 100 as a mother drawer 110 and a child drawer 120 that is retractable to the mother drawer 110, the drawer assembly 100 of this invention can achieve partitioned storage through the mother drawer 110 and the child drawer 120. Simultaneously, since the child drawer 120 can be pulled out relative to the mother drawer 110, the child drawer 120 can be opened individually, effectively reducing the loss of cold air in the refrigerator 001 compared to opening the entire drawer in the prior art.

[0056] Meanwhile, by providing an installation port 1111 on one side of the first front panel 111 of the mother drawer 110 in the left-right direction, the child drawer 120 is installed, so that the child drawer 120 is located on one side of the mother drawer 110 in the left-right direction, thereby making the space on the other side of the mother drawer 110 in the left-right direction large enough.

[0057] like Figure 5As shown, in some embodiments of this utility model, the ratio of the width L1 of the second front panel 121 in the left-right direction to the width L2 of the first front panel 111 in the left-right direction is selected from any value between 1 / 5 and 1 / 3.

[0058] For example, the ratio of L1 to L2 can be any feasible value such as 1 / 5, 1 / 4, or 1 / 3.

[0059] It should be noted that the ratio of L1 to L2 mentioned above in this invention is an approximation. For example, although the ratio of L1 to L2 is 1 / 4, the actual measurement result may be slightly larger or smaller than 1 / 4.

[0060] like Figures 3 to 7 As shown, in some embodiments of this utility model, the bottom of the first front panel 111 is provided with a first relief cavity 1112 with the opening facing downward, so that the bottom of the first front panel 111 forms a handle. The bottom end of the front side wall of the first relief cavity 1112 is higher than the bottom end of the rear side wall of the first relief cavity 1112, so as to facilitate the user to insert his / her finger into the first relief cavity 1112 and pull out the mother drawer 110.

[0061] like Figures 3 to 7 As shown, the second bottom plate 124 is provided with a second relief cavity 1241 with its opening facing downward at one end near the second front panel 121, so that the bottom of the second front panel 121 forms a handle, thereby making it convenient for the user to insert his / her fingers into the second relief cavity 1241 and pull out the sub-drawer 120 separately.

[0062] like Figures 3 to 5 As shown, the bottom end of the second front panel 121 is flush with the bottom end of the front side wall of the first clearance cavity 1112, the top end of the second front panel 121 is flush with the top end of the first front panel 111, and the left end of the second front panel 121 is flush with the left end of the first front panel 111.

[0063] Those skilled in the art will understand that the above-mentioned flush arrangement of the second front panel 121 with the first panel makes the drawer assembly 100 look more harmonious and aesthetically pleasing as a whole.

[0064] Of course, in other embodiments of this utility model, those skilled in the art can also make the two that are relatively flat in the foregoing not flat, as needed.

[0065] Furthermore, in other embodiments of this utility model, if the sub-drawer 120 is located on the right side of the first panel, the right side of the second front panel 121 can also be flush with the right side of the first front panel 111.

[0066] like Figure 6 and Figure 7As shown, in some embodiments of this utility model, the projections of the two second side panels 122 on the second front panel 121 are completely located on the second front panel 121 to ensure that the sub-drawer 120 can be inserted into the mother drawer 110 and abut against the first front panel 111 through the second front panel 121.

[0067] Continue reading Figure 6 and Figure 7 In some embodiments of this utility model, at least one of the two second side plates 122 may be provided with a front-to-back extending rib 1221 at its top end, and a groove 1113 matching the rib 1221 may be provided on the side wall of the top of the mounting port 1111, and the rib 1221 and the groove 1113 are slidably connected.

[0068] Those skilled in the art will understand that by providing a front-to-back extending rib 1221 at the top of at least one of the two second side plates 122, providing a groove 1113 matching the rib 1221 on the side wall at the top of the mounting opening 1111, and making the rib 1221 and the groove 1113 slidably connected, the sub-drawer 120 is more stable relative to the mother drawer 110.

[0069] from Figure 6 and Figure 7 As can be seen, the rib 1221 is a flange formed at the top of the second side plate 122 to enhance the structural strength of the second side plate 122.

[0070] from Figure 6 and Figure 7 It can also be seen that the second rear side panel 123 is also provided with a rib 1221 to connect the ribs 1221 on the two second side panels 122, thereby improving the overall strength of the sub-drawer 120.

[0071] Furthermore, although not explicitly shown in the figures, in some embodiments of this utility model, the depth of the groove 1113 is selected from any value between 5mm and 50mm, and may be selected from any value between 25mm and 35mm, so that the fit between the rib 1221 and the groove 1113 is long enough to act as a slide rail, thereby supporting the sliding of the child drawer 120 relative to the mother drawer 110.

[0072] The depth of the groove 1113 can be any feasible value such as 5mm, 10mm, 15mm, 25mm, 30mm, 31mm, 31.5mm, 35mm, 40mm, 45mm, or 50mm.

[0073] In addition, in other embodiments of this utility model, those skilled in the art may, as needed, configure multiple ribs 1221 for the sub-drawer 120 and distribute the ribs 1221 at intervals in the vertical direction of the sub-drawer 120 to improve the stability of the sub-drawer 120 when sliding between the sub-drawer 120 and the first front panel 111.

[0074] like Figure 8 As shown, in some embodiments of this utility model, the minimum distance between the first side panel 112 and the second side panel 122 located on the same side of the sub-drawer 120 is d, where 0 < d ≤ 5 mm. Further, 0.5 mm < d ≤ 1.5 mm.

[0075] Where d can be any feasible value, such as 0.5mm, 1mm, 1.5mm, 2.2mm, 3.5mm, 4mm, 5mm, etc.

[0076] Those skilled in the art will understand that the aforementioned distance d between the sub-drawer 120 and the mother drawer 110 ensures that the space inside the mother drawer 110 is fully utilized, while also effectively preventing the sub-drawer 120 from rubbing against the mother drawer 110 during the pushing and pulling process.

[0077] It should be noted that when there is a protruding rib 1221 on the top side of the second side plate 122, the minimum distance d between the first side plate 112 and the second side plate 122 can be measured starting from the protruding rib 1221.

[0078] like Figure 8 and Figure 9 As shown, in some embodiments of this utility model, the minimum distance between the first rear side plate 113 and the second rear side plate 123 is s, where 1mm≤s≤10mm.

[0079] Where s can be any feasible value, such as 1mm, 1.5mm, 2.2mm, 3.5mm, 4mm, 5mm, 8mm, 9.5mm, 10mm, etc.

[0080] Those skilled in the art will understand that the aforementioned distance s between the sub-drawer 120 and the mother drawer 110 ensures that the space inside the mother drawer 110 is fully utilized, while also ensuring that the first front panel 111 and the second front panel 121 abut against each other.

[0081] It should be noted that when there is a protruding rib 1221 on the top side of the second rear side plate 123, the minimum distance s between the first rear side plate 113 and the second rear side plate 123 can be measured starting from the protruding rib 1221.

[0082] like Figure 9As shown, in some embodiments of this utility model, the distance between the first base plate 114 and the second base plate 124 is h, where 1mm≤h≤10mm.

[0083] Where h can be any feasible value, such as 1mm, 1.5mm, 3mm, 4mm, 4.5mm, 5mm, 5.5mm, 8mm, 10mm, etc.

[0084] Those skilled in the art will understand that the aforementioned distance h between the child drawer 120 and the mother drawer 110 ensures that the space inside the mother drawer 110 is fully utilized, while also effectively preventing the child drawer 120 from rubbing against the mother drawer 110 during the pushing and pulling process.

[0085] Based on the foregoing description, the drawer assembly 100 of this utility model, by providing a sub-drawer 120, achieves partitioned use of the space within the mother drawer 110, allowing users to place small, loose items in the sub-drawer 120. Furthermore, the drawer assembly 100 allows users to simultaneously pull out the mother drawer 110 and the sub-drawer 120 from the refrigerator 001 through the first clearance cavity 1112 on the mother drawer 110; it also allows users to pull out only the sub-drawer 120 from the refrigerator 001 through the second clearance cavity 1241 on the sub-drawer 120.

[0086] Meanwhile, because the drawer assembly 100 of this utility model is used in partitions, the drawer assembly 100 of this utility model can also create different humidity environments through different partitions.

[0087] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments.
