DETAILED DESCRIPTION

[0048] In order to make the above objectives, features and advantages of the present application more clear and easily understood, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways from those described herein without departing from the scope of the present application. It is therefore intended that the present application not be limited to the embodiments disclosed for purposes of disclosure.

[0049] Referring to Figure 1 , the refrigerator provided by an embodiment of the present application comprises a cabinet 10 and a cabinet door 20 arranged on the cabinet 10.

[0050] Referring to Figure 1 , the cabinet 10 comprises a first cabinet 11, a second cabinet 12 and a telescopic cabinet 13.

[0051] Referring to Figure 1 and Figure 5 , the first cabinet 11 and the second cabinet 12 are arranged at intervals along a first direction of the refrigerator, and the first direction is represented by S1. The first cabinet 11 is provided with a first opening 111 and a taking and placing opening 112, and the first opening 111 and the taking and placing opening 112 are respectively arranged on two adjacent sides of the first cabinet 11. The cabinet door 20 is arranged on the taking and placing opening 112 in a hinged manner. The second cabinet 12 is provided with a second opening 121, and the first opening 111 and the second opening 121 are arranged opposite to each other.

[0052] Referring to Figure 1 , the telescopic cabinet 13 is arranged between the first cabinet 11 and the second cabinet 12, and the telescopic cabinet 13 is in communication with the first cabinet 11 and the second cabinet 12. The telescopic cabinet 13 is capable of being stretched or compressed along the first direction. Optionally, the telescopic length of the telescopic cabinet 13 is 90mm-580mm.

[0053] Specifically, referring to Figure 5 , the telescopic cabinet 13 has a first end 131 connected with the first cabinet 11 and a second end 132 connected with the second cabinet 12. The first end 131 is provided with a third opening 1311, and the first opening 111 and the third opening 1311 are in communication. The second end 132 is provided with a fourth opening 1321, and the second opening 121 and the fourth opening 1321 are in communication.

[0054] Since the telescopic cabinet 13 is arranged between the first cabinet 11 and the second cabinet 12, the user can pull the first cabinet 11 or the second cabinet 12 along the first direction, so as to stretch or compress the telescopic cabinet 13, thereby increasing or reducing the volume of the refrigerator.

[0055] When the amount of stored goods is small, the user can push the second cabinet 12 towards the first cabinet 11 or push the first cabinet 11 towards the second cabinet 12 to compress the telescopic cabinet 13, so as to reduce the volume of the refrigerator. In this way, the refrigerator can occupy less space and save electricity.

[0056] When the amount of stored goods is large, the user can pull the second cabinet 12 away from the first cabinet 11 or pull the first cabinet 11 away from the second cabinet 12 to stretch the telescopic cabinet 13, so as to increase the volume of the refrigerator. In this way, the refrigerator can store more goods.

[0057] In this way, the user can change the volume of the refrigerator according to the amount of stored goods, so that the volume of the refrigerator matches the amount of stored goods.

[0058] In one embodiment, referring to Figure 3 and Figure 4 , the telescopic cabinet 13 comprises a telescopic cabinet shell and a flexible thermal insulation layer 135. The flexible thermal insulation layer 135 is arranged in the telescopic cabinet shell.

[0059] Further, the telescopic cabinet shell comprises a telescopic inner layer 133 and a telescopic outer layer 134. The telescopic outer layer 134 is sleeved outside the telescopic inner layer 133, and the flexible thermal insulation layer 135 is arranged between the telescopic inner layer 133 and the telescopic outer layer 134.

[0060] By arranging the flexible thermal insulation layer 135 between the telescopic inner layer 133 and the telescopic outer layer 134, the flexible thermal insulation layer 135 can insulate heat, prevent external heat from entering the refrigerator, and prevent the loss of cold air in the refrigerator. In this way, the number of starts of the refrigerator can be reduced, and the purpose of saving electricity can be achieved. In addition, since the material of the flexible thermal insulation layer 135 is relatively soft, the flexible thermal insulation layer 135 will not hinder the telescoping of the telescopic inner layer 133 and the telescopic outer layer 134, so as to ensure that the telescopic cabinet 13 can normally telescope.

[0061] Optionally, the telescopic outer layer 134 is black. Of course, in other embodiments, the color of the telescopic outer layer 134 can also be the same as the color of the outer surface of the refrigerator.

[0062] Optionally, the telescopic inner layer 133 is white, but not limited thereto.

[0063] In one embodiment, the flexible thermal insulation layer 135 is a nanometer thermal insulation felt. The nanometer thermal insulation felt has an ultra-low thermal conductivity, and the telescopic box body 13 uses the nanometer thermal insulation felt to save energy. The nanometer thermal insulation felt can maintain stable thermal insulation performance at high temperature and is not prone to thermal deformation or settlement. The nanometer thermal insulation felt has a nanometer-level microporous structure and a low density, so that the mass of the nanometer thermal insulation felt is light, which can reduce the load of the refrigerator and the load of the refrigerator transportation.

[0064] Optionally, the flexible thermal insulation layer 135 can be a flexible nanometer aerogel thermal insulation felt. The thickness of the flexible nanometer aerogel thermal insulation felt is 15 mm to 40 mm, the density is 180 kg / m 3 220 kg / m 3 , and the thermal conductivity at 25°C is 0.013 W / m·K to 0.018 W / m·K.

[0065] Optionally, the flexible thermal insulation layer 135 is a flexible nanometer ceramic thermal insulation felt. The thickness of the flexible nanometer ceramic thermal insulation felt is 15 mm to 40 mm, the density is 10 kg / m 3 200 kg / m 3 , and the thermal conductivity at 25°C is 0.021 W / m·K to 0.023 W / m·K.

[0066] In one embodiment, referring to Figure 1 and Figure 5 , the telescopic inner layer 133 and the telescopic outer layer 134 are both telescopic corrugated box shells.

[0067] When the stored items are less, the corrugated box shell is compressed to reduce the volume of the refrigerator, so that the storage needs of the user can be met, the space occupied by the refrigerator can be reduced, and the electric energy can be saved. When the stored items are more, the corrugated box shell is stretched to increase the volume of the refrigerator, so that the refrigerator can store more items.

[0068] In this embodiment, by compressing and stretching the corrugated box shell, the volume of the refrigerator can be changed, which is beneficial to improve the convenience of the volume change of the refrigerator, thereby improving the efficiency of the volume change of the refrigerator. In addition, the telescopic length of the corrugated box shell can be positioned by itself without additional positioning structure, which can reduce the parts of the telescopic box body 13.

[0069] Of course, in other embodiments, the telescopic box body 13 is provided with at least two, and the adjacent two telescopic box bodies 13 are nested.

[0070] In an embodiment, the stretchable inner layer 133 and the stretchable outer layer 134 are both food-grade rubber shells. Alternatively, the stretchable inner layer 133 and the stretchable outer layer 134 are both silica gel shells, etc. In this way, the stretchable inner layer 133 and the stretchable outer layer 134 have excellent tear resistance (≥ 35 N / mm), resilience, thermal stability, and weather resistance (use temperature: -60°C to 250°C), and also have anti-yellowing properties, etc., meeting the relevant food-grade standard requirements.

[0071] In an embodiment, the stretchable inner layer 133, the stretchable outer layer 134, and the flexible insulation layer 135 are integrally compounded and formed. It can be understood that, in the factory, the stretchable inner layer 133, the stretchable outer layer 134, and the flexible insulation layer 135 are integrally compounded and formed by injecting liquid silicone rubber at high temperature to solidify into a composite to form the annular stretchable shell 13.

[0072] In an embodiment, referring to Figure 5 and Figure 6 , the first shell 11 and the door 20 are both provided with a first mounting groove 21 on an end surface facing the stretchable shell 13, and the first mounting groove 21 of the first shell 11 and the first mounting groove 21 of the door 20 are in communication to surround the first opening 111.

[0073] Specifically, the first shell 11 and the door 20 both include a color steel plate and a plastic body. The color steel plate is the outer surface of the refrigerator, and the plastic body is the inner liner of the refrigerator. In order to achieve the effect of heat preservation, polyurethane foam material is arranged between the color steel plate and the plastic body.

[0104] Optionally, referring to Figure 12 , the second box body 12 is provided with a second fixed clamping groove, and one end of the second storage plate 42 away from the first storage plate 41 is provided with a second fixed clamping site 421, which is arranged in the second fixed clamping groove. In this way, the detachable connection of the second storage plate 42 and the second box body 12 is realized.

[0105] In this way, since the first storage plate 41 and the partition plate 30 are detachably connected, and the second storage plate 42 and the second box body 12 are detachably connected, the storage rack 40 can be detached, which facilitates the cleaning of the storage rack 40.

[0106] In one embodiment, referring to Figure 12 , the third storage plate 43 is arranged in a stacked manner with the first storage plate 41 and the second storage plate 42. Optionally, the third storage plate 43 is arranged below the first storage plate 41 and the second storage plate 42. The first storage plate 41 and the third storage plate 43 are slidingly connected, and the second storage plate 42 and the third storage plate 43 are slidingly connected. In this way, the storage rack 40 can freely and infinitely extend and retract with the extension and retraction of the telescopic box body 13.

[0107] Further, referring to Figure 12 , the storage rack 40 further comprises a first sliding ring 44 and a second sliding ring 45. The first sliding ring 44 is sleeved on the first storage plate 41 and the third storage plate 43, and the second sliding ring 45 is sleeved on the second storage plate 42 and the third storage plate 43.

[0108] In one embodiment, referring to Figure 12The first storage plate 41 is provided with a first anti-disengagement part 412 at one end close to the second storage plate 42, the second storage plate 42 is provided with a second anti-disengagement part 422 at one end close to the first storage plate 41, and the third storage plate 43 is provided with a third anti-disengagement part 431 at both ends. Optionally, the first anti-disengagement part 412, the second anti-disengagement part 422 and the third anti-disengagement part 431 are all anti-disengagement hooks. In this way, the first anti-disengagement part 412, the second anti-disengagement part 422 and the third anti-disengagement part 431 can all play a limiting role, avoiding the disengagement of the first storage plate 41 and the third storage plate 43 and the disengagement of the second storage plate 42 and the third storage plate 43 during the expansion and contraction of the storage rack 40.

[0109] In one embodiment, referring to Figure 13 and Figure 15 , the third storage plate 43 comprises opposite first and second plate bodies 432 and 433. The first plate body 432 is arranged close to the first and second storage plates 41 and 42, and the second plate body 433 is arranged on the side of the first plate body 432 away from the first and second storage plates 41 and 42.

[0110] Further, referring to Figure 13 and Figure 15 , a driving member 434 is arranged between the first and second plate bodies 432 and 433. When the first and second storage plates 41 and 42 have a spacing in the first direction, the driving member 434 is used to drive the first plate body 432 located between the first and second storage plates 41 and 42 to move away from the second plate body 433, so that the first plate body 432 located between the first and second storage plates 41 and 42 is flush with the side of the first and second storage plates 41 and 42 away from the second plate body 433. In this way, the upper surface of the storage rack 40 is a flat surface, and after placing the articles on the storage rack 40, the articles can be prevented from falling and tilting, etc., ensuring the stability of the articles.

[0111] It can be understood that, for example, Figure 13 and Figure 15 , under the driving of the driving member 434, the upper surface of the first plate body 432 located between the first and second storage plates 41 and 42 is flush with the upper surfaces of the first and second storage plates 41 and 42.

[0112] In one embodiment, referring to Figure 13 and Figure 14 , the driving member 434 is an elastic member 4341. The elastic member 4341 is arranged between the first and second plate bodies 432 and 433, and can stretch and contract along the direction from the first plate body 432 to the second plate body 433.

[0113] When the shelf 40 is in the fully retracted state, the elastic member 4341 is compressed. When the shelf 40 is pulled in the first direction, the elastic member 4341 between the first shelf plate 41 and the second shelf plate 42 is gradually stretched, and the first plate body 432 between the first shelf plate 41 and the second shelf plate 42 moves away from the second plate body 433 under the action of the elastic member 4341.

[0114] Further, referring to Figure 14 , one side of the first plate body 432 towards the second plate body 433 is provided with a first support seat 4324, and one side of the second plate body 433 towards the first plate body 432 is provided with a second support seat 4331, and the first support seat 4324 and the second support seat 4331 are oppositely arranged.

[0115] Specifically, the elastic member 4341 is arranged between the first support seat 4324 and the second support seat 4331, one end of the elastic member 4341 is connected with the first support seat 4324, and the other end of the elastic member 4341 is connected with the second support seat 4331. In this way, the first support seat 4324 and the second support seat 4331 support the elastic member 4341, and facilitate the arrangement of the elastic member 4341 between the first plate body 432 and the second plate body 433.

[0116] Optionally, the first support seat 4324 and the second support seat 4331 are both metal blocks. Of course, in other embodiments, the first support seat 4324 and the second support seat 4331 can also be plastic seats, without being limited thereto.

[0117] Of course, in other embodiments, referring to Figure 15 and Figure 16 , the driving member 434 includes an electromagnet 4342. The electromagnet 4342 is provided with two, one of which is arranged on one side of the first plate body 432 towards the second plate body 433, and the other is arranged on one side of the second plate body 433 towards the first plate body 432, and the two electromagnets 4342 are oppositely arranged.

[0118] When the electromagnet 4342 is powered off, the two electromagnets 4342 have no magnetism, and the first plate body 432 between the first shelf plate 41 and the second shelf plate 42 moves towards the second plate body 433. In this way, the shelf 40 can be freely extended and retracted, so as to adjust the volume of the second storage chamber 15.

[0119] After the volume of the second storage chamber 15 is adjusted to the desired position, the two electromagnets 4342 are powered on, and the same polarity is applied to the ends of the two electromagnets 4342 that are close to each other. Due to the same-polarity repulsion characteristic of the electromagnets 4342, the first plate body 432 of the first storage plate 41 and the second storage plate 42 moves away from the second plate body 433, so that the side of the first plate body 432 of the first storage plate 41 and the second storage plate 42 that is away from the second plate body 433 is flush with the side of the first storage plate 41 and the second storage plate 42 that is away from the second plate body 433.

[0120] In one embodiment, referring to Figure 13 and Figure 15 , the storage rack 40 further comprises a first rolling member 46 and a second rolling member 47. Optionally, the first rolling member 46 and the second rolling member 47 are both rollers.

[0121] Further, the first rolling member 46 is arranged on the first storage plate 41. Specifically, the first rolling member 46 is arranged on the side of the first storage plate 41 that is close to the second storage plate 42 and faces the third storage plate 43. The second rolling member 47 is arranged on the second storage plate 42. Specifically, the second rolling member 47 is arranged on the side of the second storage plate 42 that is close to the first storage plate 41 and faces the third storage plate 43.

[0122] In one embodiment, referring to Figure 13 and Figure 15 , the first plate body 432 is provided with a plurality of limiting grooves 4321, all of which are arranged in the first direction and are used for limiting cooperation with the first rolling member 46 and the second rolling member 47. In this way, when the first rolling member 46 is limited by the limiting grooves 4321, the first storage plate 41 and the third storage plate 43 can be fixed; when the second rolling member 47 is limited by the limiting grooves 4321, the second storage plate 42 and the third storage plate 43 can be fixed.

[0123] It can be understood that the plurality of limiting grooves 4321 is equivalent to a plurality of gears, so that the storage rack 40 can be freely changed in multiple gears with the extension and retraction of the telescopic box body 13.

[0124] Optionally, the limiting grooves 4321 are arc-shaped grooves that are adapted to the first rolling member 46 and the second rolling member 47.

[0125] In one embodiment, referring to Figures 13 to 16 , the first plate body 432 comprises a flexible telescopic segment 4322 and a rigid straight segment 4323.

[0126] Referring to Figures 13 to 16The flexible expansion section 4322 and the rigid straight section 4323 are arranged along the first direction. One end of the flexible expansion section 4322 is connected with one end of the rigid straight section 4323. The end of the flexible expansion section 4322, which is away from the rigid straight section 4323, is connected with the groove wall of one of the adjacent limiting grooves 4321. The end of the rigid straight section 4323, which is away from the flexible expansion section 4322, is connected with the groove wall of the other of the adjacent limiting grooves 4321.

[0127] Further, referring to Figure 13 and Figure 15 The driving member 434 is arranged between the rigid straight section 4323 and the second plate body 433. In this way, the rigid straight section 4323 and the second plate body 433 can better support the driving member 434.

[0128] Further, referring to Figure 14 and Figure 16 When the first rolling member 46 is in limiting cooperation with the limiting groove 4321, the end of the first storage plate 41, which is close to the second storage plate 42, corresponds to the flexible expansion section 4322. When the second rolling member 47 is in limiting cooperation with the limiting groove 4321, the end of the second storage plate 42, which faces the first storage plate 41, corresponds to the flexible expansion section 4322.

[0129] In this way, under the driving of the driving member 434, the first plate body 432, which is located between the first storage plate 41 and the second storage plate 42, can move in a direction away from the second plate body 433. When the side of the first plate body 432, which is away from the second plate body 433, is flush with the side of the first storage plate 41 and the second storage plate 42, which are away from the second plate body 433, the flexible expansion section 4322, which is close to the first rolling member 46 and the second rolling member 47, is arranged obliquely. In this way, by arranging the flexible expansion section 4322, it is ensured that the first plate body 432, which is located between the first storage plate 41 and the second storage plate 42, can move in a direction away from the second plate body 433, avoiding that the movement of the first plate body 432 is hindered.

[0130] In one embodiment, referring to Figure 1 and Figure 2 The bottom of the second cabinet 12 is provided with a moving wheel 16. When the second cabinet 12 is pulled in the first direction, the moving wheel 16 moves on the ground, so that the friction between the second cabinet 12 and the ground is reduced, which is beneficial for the user to easily pull the second cabinet 12, and realizes the adjustment of the volume of the second storage room 15.

[0131] Of course, in other embodiments, the moving wheel 16 can also be arranged at the bottom of the first cabinet 11. Alternatively, the moving wheel 16 is arranged at the bottom of the first cabinet 11 and the second cabinet 12.

[0132] Further, the mobile wheel 16 has a brake structure. When the brake structure is in a non-braking state, the user can freely pull the second box 12. When the second storage chamber 15 is adjusted to the desired volume, an external force is applied to the brake structure, so that the brake structure is in a braking state, so that the refrigerator cannot be moved at will, ensuring the stability of the refrigerator.

[0133] In one embodiment, referring to Figure 1 and Figure 2 The bottom of the first box 11 is provided with a supporting foot 17. In this way, the box 10 can be better supported.

[0134] Further, the supporting foot 17 is provided with an adjusting structure for adjusting the height of the supporting foot 17. When the ground is uneven, the user can raise or lower the height of the supporting foot 17 through the adjusting structure, so that the refrigerator remains balanced, thereby ensuring the stability of the refrigerator and avoiding tilting and shaking of the refrigerator.
