[0031] The present invention provides a refrigerator 100, in which a rotatable lifting assembly 20 is provided at the bottom of the box body 10. The lifting assembly 20 is for a user to stand on and can be raised and lowered in the height direction of the refrigerator 100. Therefore, it occupies less space when lowered and retracted, and can support the user to pick up items at a higher height after being raised.

[0032] See Figure 1-Figure 2 The refrigerator 100 includes a housing 10 and a lifting assembly 20. The bottom of the housing 10 is configured with a receiving space 11. The lifting assembly 20 is received in the receiving space 11. The lifting assembly 20 is rotatably connected to the housing 10 and can rotate horizontally and leave the receiving space 11. The lifting assembly 20 can be raised and lowered along the height direction of the refrigerator 100 and can support a user standing. In this way, the receiving space 11 is used to receive the lifting assembly 20. When the lifting assembly 20 is not in use, it is stored in the receiving space 11 and does not occupy kitchen space. When the user needs to take items from the top of the refrigerator housing 10, the lifting assembly 20 can be rotated out and raised. The user can then stand on the lifting assembly 20 to reach items at a higher position and obtain a better view from above, making it easier for the user to find the items they need.

[0033] Preferably, in this embodiment, the lifting assembly 20 is rotated out of the accommodating space 11 by an electric or hydraulic method, and its elevation is also controlled by an electric control or hydraulic lifting, so as to facilitate the user's operation.

[0034] In this embodiment, a controller is provided in the refrigerator 100, which can identify and memorize the raised height of the lifting component 20 when in use and the fixed position after being rotated out. In this way, when the user needs to use the lifting component 20 next time, the lifting component 20 can be quickly rotated out to the specified position and raised to the specified height.

[0035] Specifically, this function can be activated by controlling the rotation angle, fixed position, and lifting height of the lifting assembly 20 through push-button control. A memory mode can be set to store the user's frequently used pickup station locations and the required heights. With a single push, the user can reach the desired position and height. In another embodiment, the refrigerator body 10 is equipped with an infrared sensor to automatically identify the user's height and calculate the optimal lifting height for the lifting assembly 20. Of course, the user can also select the height to be raised.

[0036] A light strip is installed at the bottom of the box 10 to sense when a user passes by, uses the box, or leaves the box. The light strip is composed of light beads and can also adaptively display different light messages according to the start and stop status of the lifting assembly 20, enhancing the user's interactive experience. Furthermore, you can also customize your own welcome light to enhance the user experience.

[0037] In other embodiments, the lifting assembly 20 may also be configured to be manually operated by the user, thereby saving costs and reducing the difficulty of the manufacturing process.

[0038] Preferably, the lifting assembly 20 is horizontally accommodated in the accommodating space 11, and the lifting assembly 20 is rotated out at an angle greater than 90° to ensure that the lifting assembly 20 is completely rotated out of the accommodating space 11 to avoid interference between the lifting assembly 20 and the box body 10 during the rising process.

[0039] The lifting assembly 20 includes a bottom plate 21, a top plate 23, and a multi-stage lifting unit 22 connected between the top plate 23 and the bottom plate 21. Adjacent lifting units 22 are movably connected, and the multi-stage lifting units 22 can move away from each other along the height direction of the refrigerator 100 to allow the top plate 23 to rise along the height direction of the refrigerator 100. In this way, the multi-stage lifting units 22 rise in coordination, and after each stage of the lifting units 22 rises a short distance, multiple stages can be stacked to achieve a higher rise height. The required rise height of each stage of the lifting units 22 is relatively small, which reduces the processing and assembly difficulty. The space occupied is also reduced, and the multi-stage lifting units 22 can be stacked and stored, thereby improving space utilization.

[0040] It can be understood that in other embodiments, the lifting assembly 20 may not be provided with a multi-stage lifting unit 22, but can directly realize the rising of the top plate 23 compared to the bottom plate 21 through a single-stage lifting unit 22, for example, by providing a motor on the bottom plate 21, the motor is connected to the screw rod and drives the screw rod to rotate, a threaded hole is opened on the top plate 23, and the screw rod is threadedly matched with the top plate 23, thereby realizing the rising of the top plate 23.

[0041] Furthermore, the lifting assembly 20 includes a drive wheel 24 and a roller member 25. The drive wheel 24 is connected to the base plate 21. The roller members 25 are provided on both sides of the base plate 21 and on the multi-stage lifting unit 22. The drive wheel 24 and the roller member 25 are both transmission-connected. Thus, through the transmission connection between the drive wheel 24 and the roller member 25, the roller member 25 can rotate, thereby driving the multi-stage lifting unit 22 to rise in response to the rotation of the drive wheel 24. There are various ways to drive the lifting unit 22 upward, such as by directly contacting the lifting unit 22 and driving it upward through rotational friction. In this embodiment, another method is adopted, which is described in detail below.

[0042] Preferably, see Figure 3-Figure 5 In this embodiment, the lifting unit 22 is provided with at least two stages, including a first lifting member 221 close to the bottom plate 21 and a second lifting member 222 close to the top plate 23. The roller member 25 on the bottom plate 21 is a third roller 253. The roller members 25 on both sides of the first lifting member 221 are provided as first rollers 251, and first guide wheels 2211 are further provided on both sides of the first lifting member 221. The roller members 25 on both sides of the second lifting member 222 are provided as second rollers 252, and second guide wheels 2221 are further provided on both sides of the second lifting member 222. The driving wheel 24 is connected to a transmission member 26, which includes a first section 261 and a second section 262 extending toward both sides of the bottom plate 21. The first section 261 is wound around the third roller 253, the first roller 251, the first guide wheel 2211, the second roller 252, and the second guide wheel 2221 on the same side and connected to the top plate 23. The second section 262 is wound around the third roller 253, the first roller 251, the first guide wheel 2211, the second roller 252, and the second guide wheel 2221 on the other side and connected to the top plate 23. In this way, Figure 3Taking the position in the figure as an example, the transmission member 26 is divided into two sections, namely the first section 261 and the second section 262. Taking the clockwise rotation of the driving wheel 24 as an example, the first section 261 is sequentially wound around the third roller 253, the first guide wheel 2211, the first roller 251, the second guide wheel 2221 and the second roller 252, and finally connected to the bottom of the top plate 23. After the clockwise rotation, the first section 261 first changes the pulling direction through the third roller 253, applies force to the first guide wheel 2211, lifts the first lifting member 221, and then changes the position through the first roller 251, synchronously lifting the second guide wheel. 2221, and finally changes the direction of the pulling force through the second roller 252, and through the connection with the top plate 23, pulls the top plate 23 upward. In other words, through the clockwise rotation of the driving wheel 24, an upward pulling force is simultaneously applied to the first guide wheel 2211, the second guide wheel 2221, and the top plate 23. Similarly, the second section 262 on the right side can also simultaneously apply an upward pulling force to the first guide wheel 2211, the second guide wheel 2221, and the top plate 23 on the right side, thereby lifting the first lifting member 221, the second lifting member 222, and the top plate 23 synchronously and achieving the lifting action. Conversely, when the driving wheel 24 rotates counterclockwise, the retraction action of the lifting assembly 20 can be completed.

[0043] It should be explained that the transmission member 26 is wound around the multiple rollers and guide wheels, which does not mean it is circumferentially wrapped around them. It only needs to be in contact with them to withstand sufficient force.

[0044] Furthermore, in order to make the ascending and descending movements of the first lifting member 221, the second lifting member 222 and the top plate 23 more stable, a mounting seat 211 is provided on the bottom plate 21, the driving wheel 24 is rotatably connected to the mounting seat 211, and bosses 2111 are provided on both sides of the mounting seat 211, and the two first rollers 251 are rotatably connected to the two bosses 2111 respectively; and / or, first slide rails 2212 are constructed on both sides of the first lifting member 221, and the two first slide rails 2212 are respectively slidably connected to the two third rollers 253; and / or, second slide rails 2222 are constructed on both sides of the second lifting member 222, and the two second slide rails 2222 are respectively slidably connected to the two first rollers 251; and / or, third slide rails 231 are constructed on both sides of the top plate 23, and the two third slide rails 231 are respectively slidably connected to the two second rollers 252. In this way, the mounting seat 211 is used to install the driving wheel 24 and the third roller 253, and the two bosses 2111 can support the rotation of the two third rollers 253. The sliding connection between the first slide rail 2212 and the third roller 253 makes the movement of the first lifting member 221 more stable. Similarly, the sliding connection between the second slide rail 2222 and the first roller 251 makes the movement of the second lifting member 222 more stable. The sliding connection between the third slide rail 231 and the second roller 252 makes the movement of the top plate 23 more stable.

[0045] Furthermore, the lengths of the bottom plate 21, the first lifting member 221, the second lifting member 222, and the top plate 23 gradually increase along the height direction of the refrigerator 100. The first lifting member 221 is slidably connected to the outer side of the third roller 253, the second lifting member 222 is slidably connected to the outer side of the first roller 251, and the top plate 23 is slidably connected to the outer side of the second roller 252. This reduces the lateral displacement of the first lifting member 221, the second lifting member 222, and the top plate 23. The lateral abutment and limiting effect of the third roller 253 and the first guide rail 2212, the lateral abutment and limiting effect of the second guide rail 2222 and the first roller 251, and the lateral abutment and limiting effect of the third guide rail 231 and the second roller 252 all contribute to the greater stability of the first lifting member 221, the second lifting member 222, and the top plate 23 during their up and down movement.

[0046] Specifically, in this embodiment, the transmission member 26 is configured as a belt, which has greater friction and a stronger ability to bear loads.

[0047] Two lifting assemblies 20 are provided, and along the width direction of the refrigerator 100, the two lifting assemblies 20 are respectively connected to the two sides of the accommodating space 11. In this way, when the user needs to take or put items at different positions on the top of the refrigerator 100, they can take or put them by using the lifting assemblies 20 at different positions.

[0048] The refrigerator 100 has a front side for mounting a door. The accommodating space 11 has an opening 111 located on the front side of the housing 10. The lifting assembly 20 pivots out of the accommodating space 11 through the opening 111. The refrigerator 100 also includes a skirting board 30 located on the front side of the housing 10 and capable of shielding at least a portion of the opening 111. This skirting board can thus conceal the internal structure of the accommodating space 11, enhancing the appearance of the refrigerator 100 and preventing the intrusion of debris.

[0049] Preferably, in this embodiment, the skirting board 30 is configured as a hinged skirting board 30 , which is provided with a plurality of hollows, so as to facilitate heat dissipation at the bottom of the refrigerator 100 .

[0050] The skirting board 30 is rotatably connected to the box body 10; and / or, the skirting board 30 is connected to the lifting assembly 20 and rotates synchronously with the lifting assembly 20.

[0051] Specifically, when the skirting board 30 is rotatably connected to the body 10, it is preferably arranged to cover the opening 111 from one end to the other end along the width direction of the refrigerator 100. The skirting board 30 can be lifted up as a whole, or rotated downward and completely cover the opening 111.

[0052] See Figure 6When the skirting board 30 is connected to the lifting assembly 20, the consistency of the two and the aesthetics of the refrigerator 100 can be increased. Preferably, the skirting board 30 and the lifting assembly 20 are provided in one piece.

[0053] Furthermore, the height of the accommodating space 11 is preferably set to 150 mm. The lifting assembly 20 rotates about the front bottom angle axis to the front space of the refrigerator 100. The height can be raised by up to 120 mm. Combined with the minimum height of the platform, the user can increase the height of the lifting platform by 266 mm. For an adult with a height of 1.5 meters, standing on the lifting platform, the maximum height can reach 176 cm. Currently, the maximum height of refrigerators 100 on the market does not exceed 2 meters, which is sufficient for users to take out the refrigerator.

[0054] Compared to the prior art, the present invention solves the problem of users having difficulty accessing items high up in the refrigerator by providing a lifting assembly 20. When a user needs to access items at the top of the refrigerator body 10, they can rotate the lifting assembly 20 out and raise it, allowing them to stand on it and reach higher-placed items. The accommodating space 11 is used to accommodate the lifting assembly 20. When not in use, the lifting assembly 20 is stored in the accommodating space 11, eliminating kitchen space and protecting the lifting assembly 20.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0056] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
