Description

Technical Field

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

[0002] The high storage compartments of existing refrigerators are often used to store infrequently used items or left unused because they are difficult for users to reach, resulting in low space utilization. Furthermore, for shorter users such as women and children, reaching items in the high storage compartments requires standing on tiptoe or using external tools, causing inconvenience.

[0003] Existing technology involves creating a receiving cavity at the bottom of the refrigerator, within which a lifting platform that can roll out via casters is installed. When a user retrieves items from the higher storage areas of the refrigerator, the lifting platform rolls out and locks itself via the casters. The user can then stand on the platform to retrieve the item. After retrieval, the casters unlock, and the platform rolls back into the receiving cavity. Because the lifting platform is independent of the refrigerator, its relative position to the refrigerator may shift during use. Firstly, the lifting platform may shift due to collisions or other reasons, posing a risk to the user. Secondly, if the lifting platform shifts during use, manual adjustment is required to return it correctly to the receiving cavity, making its use more cumbersome. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator that allows users to conveniently and safely access items in the high-level storage area.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A refrigerator, comprising:

[0007] The refrigerator body includes a base, on which a receiving cavity is provided;

[0008] A welcoming lifting platform includes a support, a supporting platform, and a lifting drive mechanism. The lifting drive mechanism is mounted on the support and is connected to the supporting platform in a transmission manner. The supporting platform can move up and down relative to the support under the drive of the lifting drive mechanism.

[0009] A telescopic drive mechanism is housed within the accommodating cavity and is connected to the base and the support respectively. The telescopic drive mechanism is capable of pushing the support to perform telescopic movement relative to the base.

[0010] The welcoming lifting platform has a first state and a second state. When the welcoming lifting platform is in the first state, it is housed within the receiving cavity. When the welcoming lifting platform is in the second state, the supporting platform is located outside the receiving cavity, and the supporting platform is raised a preset distance from the support under the drive of the lifting drive mechanism.

[0011] Understandably, by setting up a telescopic drive mechanism that is connected to both the base and the support, the lifting platform can only move in the depth direction relative to the refrigerator body. When the user uses the lifting platform to retrieve items placed in the high storage area of ​​the refrigerator, the lifting platform will not move along the width direction of the refrigerator body due to collision, thus improving user safety. Since the position of the lifting platform relative to the refrigerator body does not move during use, the telescopic drive mechanism can be retracted and the lifting platform returned to the receiving cavity after use, making it convenient for users to use.

[0012] In one embodiment, the telescopic drive mechanism is configured to be multiple sets, and the multiple sets of telescopic drive mechanisms are arranged at intervals along the width direction of the refrigerator body;

[0013] Furthermore, the support can extend or retract relative to the base under the combined drive of multiple telescopic drive mechanisms.

[0014] Understandably, by setting up multiple telescopic drive mechanisms and using these mechanisms to drive the support to telescopically move relative to the base, the telescopic mechanisms push the support to move through multiple contact points, avoiding the problem of tilting or jamming caused by single-point force, thus improving the stability and smoothness of the support's movement.

[0015] In one embodiment, the telescopic drive mechanism includes a telescopic drive component and multiple telescopic sleeves, which are sequentially connected end to end. Furthermore, the first and last two telescopic sleeves in the depth direction of the refrigerator body are respectively connected to the base and the support.

[0016] The telescopic drive component is housed inside the multiple telescopic sleeves and is used to control the telescopic deformation of the multiple telescopic sleeves and to control the telescopic movement of the support.

[0017] Understandably, by setting up a telescopic sleeve and placing the telescopic drive component inside the telescopic sleeve, the telescopic sleeve can protect the telescopic drive component. On the one hand, it can prevent dust, moisture, and other substances from entering the telescopic drive component. On the other hand, it can prevent the telescopic drive component from tilting or shifting due to external forces after it extends, thus extending the service life of the telescopic drive component.

[0018] In one embodiment, any two adjacent telescopic sleeves among the plurality of telescopic sleeves are slidably connected.

[0019] In one embodiment, the support is slidably connected to the base.

[0020] Understandably, by sliding the support to the base, the support can slide with the base when it extends or retracts. Therefore, the support can move only relative to the base in the depth direction of the refrigerator, making the extension and retraction of the support relative to the base more stable.

[0021] In one embodiment, the base includes a supporting base plate, and the base is slidably connected to the support via the supporting base plate;

[0022] The telescopic drive mechanism is located directly above the support base plate in the height direction of the refrigerator.

[0023] In one embodiment, the welcoming lift platform further includes support wheels, which are rotatably mounted on the support for supporting the support.

[0024] Understandably, by installing support wheels, the welcome lift can be supported during use, preventing excessive pressure on the welcome lift from causing the refrigerator to tip over, thus improving the stability of the welcome lift during use.

[0025] In one embodiment, the number of lifting drive mechanisms is configured to be one;

[0026] The connection point between the support platform and the lifting drive mechanism is located at the center of gravity of the support platform.

[0027] In one embodiment, the lifting drive mechanism includes a lifting drive component and multiple lifting sleeves, which are sequentially connected end to end. Furthermore, the first and last two lifting sleeves in the height direction of the refrigerator body are respectively connected to the support and the supporting platform.

[0028] The lifting drive component is housed inside multiple lifting sleeves and is used to control the extension and contraction of the multiple lifting sleeves and to control the lifting movement of the supporting platform.

[0029] Understandably, by setting up a lifting sleeve and placing the lifting drive component inside the lifting sleeve, the lifting sleeve can protect the lifting drive component. On the one hand, it can prevent foreign objects such as dust and moisture from entering the lifting drive component, and on the other hand, it can prevent the lifting drive component from tilting or shifting due to external forces after it extends, thus extending the service life of the lifting drive component.

[0030] In one embodiment, any two adjacent lifting sleeves among the plurality of lifting sleeves are slidably connected.

[0031] It is understandable that by setting any two adjacent lifting sleeves in a series of lifting sleeves to slide together, the connection between the lifting sleeves does not require a complex hinge design, thus reducing the manufacturing cost of the lifting sleeves.

[0032] Compared to existing technologies, this refrigerator features a telescopic drive mechanism that is connected to both the base and the support, ensuring that the lifting platform can only move in the depth direction relative to the refrigerator body. When a user uses the lifting platform to retrieve items from the high storage area of ​​the refrigerator, the platform will not move along the width direction of the refrigerator body due to collision, thus improving user safety. Since the lifting platform's position relative to the refrigerator body does not move during use, the telescopic drive mechanism can be retracted after use, and the platform can be returned to its accommodating cavity, making it convenient for users.

[0046] Please see Figures 1 to 5 This application provides a refrigerator 100, which includes: a refrigerator body 10, a welcome lift platform 20, and a telescopic drive mechanism 30. The refrigerator body 10 includes a base 11 with a receiving cavity 111. The welcome lift platform 20 includes a support 21, a supporting platform 22, and a lift drive mechanism 23. The lift drive mechanism 23 is mounted on the support 21 and is connected to the supporting platform 22, and the supporting platform 22 can move up and down relative to the support 21 under the drive of the lift drive mechanism 23. The telescopic drive mechanism 30 is housed in the receiving cavity 100. The cavity 111 is connected to the base 11 and the support 21 respectively, and the telescopic drive mechanism 30 can push the support 21 to make telescopic movement relative to the base 11; wherein, the welcoming lifting platform 20 has a first state and a second state. When the welcoming lifting platform 20 is in the first state, the welcoming lifting platform 20 is housed in the cavity 111; when the welcoming lifting platform 20 is in the second state, the supporting platform 22 is disposed on the outside of the cavity 111, and the supporting platform 22 is raised from the support 21 by a preset distance under the drive of the lifting drive mechanism 23.

[0047] As can be seen from the above, by setting the telescopic drive mechanism 30 to be connected to the base 11 and the support 21 respectively, the relative position of the welcoming lift platform 20 is fixed. When the user uses the welcoming lift platform 20 to retrieve items placed in the high storage area of ​​the refrigerator 100, the welcoming lift platform 20 will not move due to collision, thereby improving the safety of the user when using the welcoming lift platform 20. Since the position of the welcoming lift platform 20 relative to the refrigerator 100 does not move during use, the telescopic drive mechanism 30 can be retracted and the welcoming lift platform 20 can be returned to the receiving cavity 111 after use, making it convenient for the user to use the welcoming lift platform 20.

[0048] like Figure 1 and Figure 2 As shown, the support 21 is slidably connected to the base 11. Here, the slidable connection between the support 21 and the base 11 can be achieved by a slider and a groove or a rail and a groove. By slidably connecting the support 21 and the base 11, the support 21 can slide and engage with the base 11 when extending or retracting, thereby making the extension and retraction of the support 21 relative to the base 11 more stable.

[0049] In this embodiment, a slide rail 113 is provided on the base 11 and a slide groove 211 is provided on the support 21. The slide rail 113 and the slide groove 211 cooperate to achieve a sliding connection between the support 21 and the base 11.

[0050] In one embodiment, the base 11 includes a supporting base plate 112, and the base 11 is slidably connected to the support 21 through the supporting base plate 112; wherein, the telescopic drive mechanism 30 is disposed directly above the supporting base plate 112 in the height direction of the refrigerator 100.

[0051] In this embodiment, the number of support base plates 112 is configured to be two, and the two support base plates 112 are located on both sides of the refrigerator 100 along the width direction.

[0052] like Figure 1 and Figure 4 As shown, the number of lifting drive mechanisms 23 is configured to be one; the connection point between the supporting platform 22 and the lifting drive mechanism 23 is located at the center of gravity of the supporting platform 22. By setting only one lifting mechanism, the lifting requirements are met while reducing the usage cost of the lifting drive mechanism 23. In other embodiments, multiple lifting drive mechanisms 23 can also be used, such as two or three.

[0053] In one embodiment, the lifting drive mechanism 23 includes a lifting drive component (not shown) and multiple lifting sleeves 231. The multiple lifting sleeves 231 are sequentially connected end to end, and the first and last two lifting sleeves 231 in the height direction of the refrigerator body 10 are respectively connected to the support 21 and the supporting platform 22. The lifting drive component is housed inside the multiple lifting sleeves 231 and is used to control the extension and contraction deformation of the multiple lifting sleeves 231 and control the lifting movement of the supporting platform 22. Thus, by setting up the lifting sleeves 231 and placing the lifting drive component inside the lifting sleeves 231, the lifting sleeves 231 can protect the lifting drive component. On the one hand, it can prevent foreign objects such as dust and moisture from entering the lifting drive component, and on the other hand, it can prevent the lifting drive component from tilting or shifting due to external forces after it extends, thus extending the service life of the lifting drive component. Specifically, the lifting drive component is configured as a motor push rod, hydraulic push rod, etc. The end of the push rod is fixed to one end of the lifting sleeve 231 closest to the support platform 22, so that the lifting drive component can drive the lifting sleeve 231 to extend and retract.

[0054] Here, the number of lifting sleeves 231 can be configured as two, three, four, etc.

[0055] In this embodiment, the number of lifting sleeves 231 is configured as two. One lifting sleeve 231 connected to the support 21 can be partially disposed inside the support 21 and sleeved with the support. The limiting block 2312 on the lifting sleeve 231 and the keyway 2311 provided on the support 21 can cooperate with each other to realize the sliding connection of the lifting sleeve 231 on the support 21.

[0056] like Figure 4 As shown, any two adjacent lifting sleeves 231 among the multiple lifting sleeves 231 are slidably connected. By setting any two adjacent lifting sleeves 231 among the multiple lifting sleeves 231 to be slidably connected, the connection between the lifting sleeves 231 does not require a complex hinge design, thus reducing the manufacturing cost of the lifting sleeves 231.

[0057] Specifically, the lifting sleeve 231 is provided with a keyway 2311 and a limiting block 2312. The limiting block 2312 is snapped into the keyway 2311 between two adjacent lifting sleeves 231. The two lifting sleeves 231 can extend and retract through the cooperation between the limiting block 2312 and the keyway 2311. The extension and retraction distance between two adjacent lifting sleeves 231 is controlled by controlling the length of the keyway 2311.

[0058] In one embodiment, the welcoming lift platform 20 further includes support wheels 24, which are rotatably mounted on the support 21 to support the support 21. It is understood that by providing the support wheels 24, the welcoming lift platform 20 provides support during use, preventing the refrigerator 100 from tipping over due to excessive weight, thus improving the stability of the welcoming lift platform 20 during use.

[0059] like Figure 1 and Figure 2 As shown, multiple sets of telescopic drive mechanisms 30 are configured, and these multiple sets of telescopic drive mechanisms 30 are arranged at intervals along the width direction of the refrigerator body 10. Furthermore, the support 21 can telescopically move relative to the base 11 under the combined drive of the multiple sets of telescopic drive mechanisms 30. In this way, by setting multiple sets of telescopic drive mechanisms 30 and driving the support 21 to telescopically move relative to the base 11 through multiple contact points, the telescopic drive mechanisms 30 push the support 21 to move, avoiding the problem of tilting or jamming caused by single-point force, and improving the stability and smoothness of the movement of the support 21.

[0060] Here, the number of telescopic drive mechanisms 30 can be configured as two, three, four, etc.

[0061] In this embodiment, the telescopic drive mechanism 30 is configured to be two sets.

[0062] In one embodiment, the telescopic drive mechanism 30 includes a telescopic drive component (not shown) and multiple telescopic sleeves 31. The multiple telescopic sleeves 31 are sequentially connected end to end, and the first and last two telescopic sleeves 31 in the depth direction of the refrigerator body 10 are respectively connected to the base 11 and the support 21. The telescopic drive component is housed inside the multiple telescopic sleeves 31 and is used to control the telescopic deformation of the multiple telescopic sleeves 31 and control the telescopic movement of the support 21. By setting the telescopic sleeves 31 and placing the telescopic drive component inside the telescopic sleeves 31, the telescopic sleeves 31 can protect the telescopic drive component. On the one hand, it can prevent dust, moisture, etc. from entering the telescopic drive component, and on the other hand, it can prevent the telescopic drive component from tilting or shifting due to external forces after it extends, thus extending the service life of the telescopic drive component.

[0063] Specifically, the telescopic drive component can be configured as a motor push rod, a hydraulic push rod, etc. By fixing the end of the push rod to one end of the telescopic sleeve 31 closest to the support 21, the telescopic drive component can drive the telescopic sleeve 31 to extend or retract.

[0064] Here, the number of telescopic sleeves 31 can be configured as three, four, five, etc.

[0065] In this embodiment, the number of telescopic sleeves 31 is configured as three.

[0066] In one embodiment, any two adjacent telescopic sleeves 31 are slidably connected. It can be understood that by setting any two adjacent telescopic sleeves 31 to be slidably connected, the connection between the telescopic sleeves 31 does not require a complex hinge design, thus reducing the manufacturing cost of the telescopic sleeves 31.

[0067] Furthermore, the telescopic sleeve 31 is provided with a keyway 2311 and a limiting block 2312. The limiting block 2312 is engaged in the keyway 2311 between two adjacent telescopic sleeves 31. The cooperation between the limiting block 2312 and the keyway 2311 enables the two telescopic sleeves 31 to telescopically cooperate. The telescopic distance between two adjacent telescopic sleeves 31 is controlled by controlling the length of the keyway 2311.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
