Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] Refrigerators are common household appliances that maintain a constant low temperature inside. They are often used to preserve food, cosmetics, and medicine, making them indispensable in modern household life. However, refrigerators typically have side-opening doors, requiring squatting or bending over to reach items below. This is difficult for individuals with physical disabilities, such as the elderly and pregnant women. Furthermore, these structures place the refrigeration unit at the rear of the refrigerator, causing higher temperatures near the door when the door is opened, leading to uneven temperatures inside the refrigerator. Refrigerators with top-opening doors can help address this issue.

[0003] However, at present, top-opening refrigerators are smaller in size and can accommodate fewer items. In addition, when taking items out of the refrigerator, all items will be exposed. The performance and life of some items that need to be shielded from light are affected due to exposure. Utility Model Content

[0004] Based on this, it is necessary to provide a refrigerator that can effectively ensure that some products are still in a light-shielded and refrigerated state when taking items.

[0005] To solve the above technical problems, this application provides the following technical solutions:

[0006] A refrigerator, comprising:

[0007] A box body having a storage chamber therein, wherein the storage chamber has a first opening on an end surface in a height direction of the box body;

[0009] a drawer assembly housed in the storage chamber, the drawer assembly comprising a connecting rod, a drawer, and a cover; the drawer being movably housed in the storage chamber and having a second opening disposed toward the first opening; the drawers comprising a first drawer and a second drawer; the first drawer and the second drawer being spaced apart along an axis of the storage chamber, with the first drawer being disposed proximate to the opening and relatively above the second drawer; and the connecting rod connecting the first drawer and the second drawer into a whole;

[0010] A lifting assembly is provided in the storage chamber and connected to the second drawer, and is used to drive the drawer assembly to move along the axis direction of the storage chamber so that the second drawer can be exposed to the opening.

[0011] It is understandable that the present application provides a first drawer and a second drawer, and arranges the first drawer and the second drawer in an up-down manner along the axis direction of the storage chamber, and then uses a lifting assembly to lift the first drawer and the second drawer as a whole. In this way, a multi-layer structure can be formed inside the box body, so that items can be stored in layers, thereby improving the space utilization rate inside the refrigerator. At the same time, by using the lifting assembly, when taking items from the first drawer during use, it can be ensured that the second drawer is still in a light-shielded refrigerated state, which is convenient for users to store items such as medicines and / or cosmetics that require light protection and refrigeration. In addition, in combination with the lifting assembly, the second drawer can be lifted and lowered to the first opening position for taking and placing items, so that users do not need to bend over to operate, which is more convenient to use.

[0012] In one embodiment, the lifting assembly includes a driving member and a lifting unit, the lifting unit is connected to the second drawer, and the driving member is connected to the lifting unit, and is used to control the lifting unit to lift and lower along the axial direction of the storage chamber to drive the second drawer to lift and lower.

[0013] In one embodiment, the lifting unit includes a base and a lifting member, the base is installed at the bottom of the box along the axis of the storage chamber, and the lifting member or the driving member is installed on the base;

[0014] Wherein, the lifting member is connected to the driving member and the second drawer respectively.

[0024] In one embodiment, the lifting assembly further includes a position detector, which is located in the storage chamber and mounted on the box body, and is used to detect the position of the second drawer in the storage chamber.

[0025] In one embodiment, the lifting assembly further includes a protective cover, which is arranged around the circumference of the position detector.

[0026] It can be understood that the protective cover can reduce the occurrence of situations where the position detector is accidentally touched, causing the drawer to stop moving before reaching the specified height, thereby increasing the practicality of the position detector during use.

[0027] Compared with the prior art, the refrigerator is provided with a first drawer and a second drawer, and the first drawer and the second drawer are arranged in an up-down manner along the axis direction of the storage chamber, and then a lifting assembly is used to lift the first drawer and the second drawer as a whole. In this way, a multi-layer structure can be formed inside the box, so that items can be stored in layers, thereby improving the space utilization rate inside the refrigerator. At the same time, the lifting assembly can ensure that the second drawer is still in a light-shielded refrigerated state during use when taking items from the first drawer, which makes it convenient for users to store items such as medicines and / or cosmetics that require light protection and refrigeration. In addition, combined with the lifting assembly, the second drawer can be lifted and lowered to the first opening position for taking and placing items, so that users do not need to bend over to operate, which is more convenient to use.

[0040] See also Figures 1 to 3 The present application provides a refrigerator 100, which includes a housing 10, a cover 20, and a drawer assembly 30. The housing 10 has a storage chamber 11 therein. The storage chamber 11 has a first opening 12 at an end in the height direction of the housing 10. The cover 20 is connected to the housing 10 and is located at the first opening 12, and is used to open or close the first opening 12. The drawer assembly 30 is accommodated in the storage chamber 11 and is used to store items such as medicines, food, and cosmetics.

[0041] For further information, please refer to Figures 1 to 3The drawer assembly 30 includes a connecting rod 31, a drawer 32, and a cover 33. The drawer 32 is movably received within the storage chamber 11 and has a second opening 34 disposed toward the first opening 12. The drawer 32 includes a first drawer 321 and a second drawer 322. The first drawer 321 and the second drawer 322 are spaced apart along the axis of the storage chamber 11, with the first drawer 321 positioned adjacent to the first opening 12 and relatively above the second drawer 322. The connecting rod 31 connects the first drawer 321 and the second drawer 322 as a single unit. The refrigerator 100 also includes a lifting assembly 40 disposed within the storage chamber 11 and connected to the second drawer 322. The lifting assembly 40 is configured to drive the drawer assembly 30 along the axis of the storage chamber 11 so that the second drawer 322 is exposed at the first opening 12. By arranging the first and second drawers in an up-and-down arrangement along the axis of the storage chamber 11, the lifting assembly 40 is used to raise and lower the second drawer 322. In this way, a multi-layered structure is formed within the housing 10, allowing items to be stored in layers, improving the space utilization within the refrigerator 100. Furthermore, the lifting assembly 40 ensures that the second drawer 322 remains in a light-shielded, refrigerated state while items are being retrieved from the first drawer 321. This facilitates the storage of items such as medications and cosmetics that require both light protection and refrigeration. Furthermore, the lifting assembly 40 allows the second drawer 322 to be raised and lowered to the first opening 12 for easy access, eliminating the need for users to bend over, making it more convenient.

[0042] like Figure 1 As shown, the box body 10 is in the shape of an elongated strip, and its shape can be cylindrical or rectangular, etc. The first opening 12 is located at the top of the box body 10, so that it forms a top-opening refrigerator.

[0043] Furthermore, the cover plate 20 and the box body 10 can be connected by hinge connection, snap connection, etc. In this embodiment, the cover plate 20 and the box body 10 are hingedly connected so that the cover plate 20 can rotate relative to the box body 10 to open or close the first opening 12.

[0044] As preferably, Figure 3 As shown, in order to facilitate opening the cover 20, a handle 21 is provided on the cover 20. Thus, when it is necessary to open the cover 20, the user holds the handle 21 and rotates the cover 20 relative to the box body 10.

[0045] like Figures 1 to 2 As shown, the number of drawers 32 is not limited to the first drawer 321 and the second drawer 322. It may also include a third drawer, a fourth drawer, etc. The number of drawers 32 can be set according to actual needs. In this embodiment, two drawers are used as an example to specifically explain the working process and principle of this application.

[0046] The connection between the cover 33 and the drawer 32 can be a snap connection or a hinge connection.

[0047] In one embodiment, the lifting assembly 40 includes a driving member 41 and a lifting unit 42. The lifting unit 42 is connected to the second drawer 322. The driving member 41 is connected to the lifting unit 42 and is used to control the lifting unit 42 to lift and lower the second drawer 322 so as to be driven to lift and lower the second drawer 322 through the lifting unit 42.

[0048] Here, the driving member 41 can be a cylinder, an oil cylinder or other components.

[0049] like Figure 1 and Figure 2 As shown, the lifting unit 42 includes a base 421 and a lifting member 422. The base 421 is installed at the bottom of the box body 10 along the axial direction of the storage chamber 11, and the lifting member 422 or the driving member 41 is installed on the base 421; wherein, the lifting member 422 is respectively connected to the driving member 41 and the second drawer 322.

[0050] Here, the lifting member 422 can be a structure such as a telescopic rod or a lifting arm.

[0051] In this embodiment, the lifting member 422 is configured as a lifting arm 4221, and the number of the lifting arms 4221 is set to at least one group, and each group is provided with multiple lifting arms 4221; wherein, one end of at least one group of lifting arms 4221 is rotatably connected to the base 421, and the other end is connected to the second drawer 322.

[0052] Furthermore, if Figure 1 or Figure 2 As shown, the number of lifting arms 4221 is set to at least two groups, which are respectively configured as a first lifting arm group and a second lifting arm group; and, in each lifting arm group, multiple lifting arms 4221 are crossed and rotatably connected to each other; wherein, the first lifting arm group is rotatably connected to the base 421, the second lifting arm group is rotatably connected to the second drawer 322, and the first lifting arm group and the second lifting arm group are rotatably connected to each other; the driving member 41 is configured as a hydraulic cylinder, the cylinder body of the hydraulic cylinder is installed on one of the lifting arm groups, and the movable end of the hydraulic cylinder is connected to the other lifting arm group.

[0053] Specifically, in the first lifting arm group, there are two lifting arms 4221, which are intersecting and hingedly connected. One end of one lifting arm 4221 is hingedly connected to the base 421 and serves as a fixed point, while one end of the other lifting arm 4221 is hingedly connected to the base 421 and serves as a moving point, with its movement direction perpendicular to the axis of the storage chamber 11. During use, a hydraulic cylinder drives the lifting arm 4221 to rotate relative to the base 421. The fixed point remains in place, while the moving point slides on the corresponding base 421, thereby causing the lifting arm 4221 to extend and retract, thereby achieving the lifting and lowering movement of the drawer 32.

[0054] Of course, the number of lifting arms 4221 is not limited to two groups, and can be three, four, etc. The number of groups of lifting arms 4221 can be set according to the required lifting height. Multiple groups of lifting arms 4221 are connected end to end to form a lifting member 422.

[0055] Furthermore, the lifting assembly 40 includes a lifting switch 43, which is mounted on the cover 20 or the housing 10 and electrically connected to the driver 41 to control the opening and closing of the driver 41. To raise or lower the second drawer 322, simply press the lifting switch 43 on the cover 20. This activates the driver 41 and drives the lifting member 422 along the axis of the housing 10, thereby raising or lowering the second drawer 322. This allows the lifting switch 43 to move the second drawer 322 with one click, making it more convenient to use.

[0056] like Figure 4 As shown, the lifting assembly 40 further includes a position detector 44, which is located in the storage chamber 11 and mounted on the box body 10, and is used to detect the position of the second drawer 322 in the storage chamber 11. In this way, the position of the second drawer 322 can be accurately controlled by the position detector 44, so that it can be accurately moved to the second opening 34.

[0057] Here, the position detector 44 may be a proximity switch, a GPS detector, a position tracking detector, a position sensor, or the like.

[0058] Please continue to refer to Figure 4 The lifting assembly 40 further includes a protective cover 45 , which is disposed around the circumference of the position detector 44 , thereby protecting the position detector 44 through the protective cover 45 to prevent the position detector 44 from being falsely triggered.

[0059] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
