[0041] The following is combined with Figures 1 to 10 The technical solution of the utility model is further illustrated by specific implementation methods.

[0042] A freezer with an inner layer blocking structure comprises a cabinet body and a cover body assembly, wherein the cabinet body comprises an inner liner 12, and an access opening of the inner liner 12 is arranged upward, and the cover body assembly is provided with a storage space, and the storage space is connected with the inner liner 12 through the access opening; a rolling shutter assembly is installed inside the inner liner 12, and when the rolling shutter assembly is rolled up, the storage space is connected with the inner liner, and when the rolling shutter assembly is unfolded, an inner layer blocking structure is formed between the storage space and the inner liner 12, and the inner layer blocking structure is used to block the connection between the storage space and the inner liner 12.

[0043] like Figures 1 to 4 As shown, the cover assembly is arranged at the upper part of the cabinet, and the storage space of the cover assembly is connected with the inner liner 12 through the access opening. A roller shutter assembly is installed inside the inner liner 12, and the roller shutter assembly can cover or open the access opening of the inner liner 12 according to the use needs. When the roller shutter assembly is in a rolled-up state, the storage space of the cover assembly is connected with the inner liner 12; when the roller shutter assembly is unfolded, an inner layer blocking structure is formed between the storage space and the inner liner 12 to block the connection between the storage space and the inner liner 12. By arranging the roller shutter assembly in the inner liner 12 to block the connection between the storage space and the inner liner 12, the cold air in the inner liner 12 is effectively blocked from leaking to the upper storage space, the refrigeration effect of the inner liner 12 is improved, and the energy consumption of the freezer is reduced.

[0044] Furthermore, the rolling shutter assembly includes a rolling shutter box 41, a rolling shutter cloth 42, a reel 43, a pull rod 44 and a reset member;

[0045] The rolling shutter box 41 is installed on one side of the cabinet, and a fixing piece is provided on one side of the refrigerator relative to the rolling shutter box 41;

[0046] The reel 43 is disposed in the shutter box 41, and the reel 43 is rotatably connected to the shutter box 41; the shutter cloth 42 is wound around the reel 43, one end of the shutter cloth 42 is fixedly connected to the reel 43, and a strip-shaped fixing block 45 is installed at the other end of the shutter cloth 42, and the strip-shaped fixing block 45 extends along the width direction of the shutter cloth 42;

[0047] The pull rod 44 includes two mounting portions 441 and a pull rod portion 442. The two mounting portions 441 are connected to the two ends of the pull rod portion 442 through a connecting portion. The mounting portions 441 and the pull rod portion 442 are parallel to each other. The two ends of the bar-shaped fixing block 45 are provided with mounting holes 451. The two mounting portions 441 are rotatably mounted to the mounting holes 451 at the two ends respectively.

[0048] The reset member is disposed in the rolling shutter box 41 and is used to drive the reel 43 to reel in the rolling shutter fabric 42;

[0049] When the rolling curtain assembly is unfolded, the fixing member is used to fix the pull rod portion 442 , and the rolling curtain cloth 42 forms an inner layer blocking structure between the storage space and the inner liner 12 , and the rolling curtain cloth 42 is used to block the connection between the storage space and the inner liner 12 .

[0050] like Figure 3 , Figure 4 and Figure 7 As shown, the shutter box 41 is fixedly arranged in the cabinet, and the reel 43 with the shutter cloth 42 wound thereon is rotatably arranged in the shutter box 41. The shutter cloth 42 is connected to a strip-shaped fixing block 45 and one end of the pull rod 44 is exposed in the shutter box 41. By pulling the pull rod 44, the shutter cloth 42 drives the reel 43 to rotate, and the shutter cloth 42 rotates out of the shutter box 41 and unfolds along with the pull rod 44; the pull rod portion 442 of the pull rod 44 is fixed to the fixing member, so that the shutter cloth 42 remains in the unfolded state, covering between the inner liner 12 and the storage space, forming an inner layer blocking structure. When the shutter cloth 42 is not needed to block the inner liner 12 and the storage space, the pull rod portion 442 is released from the fixing member, and the reset member in the shutter box 41 will reversely drive the shutter cloth 42 to roll back into the shutter box 41. Specifically, the reset member is a coil spring.

[0051] A strip fixing block 45 is installed at the movable end of the rolling curtain 42, and the strip fixing block 45 is extended along the width direction of the rolling curtain 42 to keep the rolling curtain 42 unfolded in the width direction. When the rolling curtain 42 is pulled out from the rolling curtain box 41 to block the storage space and the inner liner 12, it is more efficient.

[0052] Both ends of the strip-shaped fixing block 45 are provided with mounting holes 451 for mounting the mounting portion 441 of the pull rod 44. The mounting portion 441 is rotatably mounted in the mounting holes 451. The pull rod 44 can flexibly rotate around the strip-shaped fixing block 45, making it more flexible and convenient to pull out the rolling curtain 42. The pull rod portion 442 of the pull rod 44 is connected to the mounting portion 441 through a connecting portion, and the pull rod portion 442 and the mounting portion 441 are parallel to each other, which is equivalent to the pull rod 44 being an unclosed annular member. Such an annular pull rod 42 has a simple bending process, and the large pull rod portion 442 also provides convenience for users.

[0053] Furthermore, the cabinet includes an outer shell 11 and a mounting plate 13 , the inner tank 12 is disposed in the outer shell 11 , the mounting plate 13 is mounted on the upper surface of the outer shell 11 , and the cover assembly is fixedly mounted on the top of the outer shell 11 through the mounting plate 13 .

[0054] The inner container 12 is disposed in the outer shell 11 , and the cover assembly is fixedly mounted on the top of the outer shell 11 through the mounting plate 13 , so that the connecting space between the storage space and the inner container 12 is more compact, and the overall structure and function of the refrigerator are more reasonable. Preferably, the shutter box 41 can be mounted on the mounting plate 13 .

[0055] Furthermore, the cover body assembly includes an upper cover 2 and a sliding door 3, an opening is provided on one side of the upper cover 2, and axial holes are respectively provided at both ends of the opening, and hinge shafts 31 are provided at both ends of the sliding door 3, and the hinge shafts 31 are rotatably connected with the corresponding axial holes, and the sliding door 3 flips up and down with the hinge shafts 31 as a fulcrum; when the sliding door 3 is closed downward, the upper cover 2 and the sliding door 3 jointly cover the inner liner 12, and when the sliding door 3 is opened upward, the sliding door 3 is embedded in the upper cover 2.

[0056] The upper cover 2 and the sliding door 3 cover the inner container 12 together, and are used to prevent foreign objects from entering the inner container 12 and contaminating the internal storage space. The hinge shaft 31 can rotate around the shaft hole, so that the sliding door 3 can be turned up and down with the hinge shaft 31 as the fulcrum, instead of being pushed and pulled horizontally left and right, thereby expanding the user's operating space, and the operating space can extend to the entire inner container 12. The sliding door 3 can be turned up 90° to achieve full opening of the storage space, which is more convenient for sorting or other operations of the items in the freezer.

[0057] Furthermore, the fixing member is mounted on the mounting plate 13 , and the fixing member is arranged opposite to the rolling shutter box 41 .

[0058] In one embodiment of the utility model, the fixing member is installed on the mounting plate 13, specifically on the side opposite to the rolling shutter box 41. The fixing member is used in conjunction with the pull rod portion 442, specifically for snapping the pull rod portion 442, thereby limiting the rewinding operation of the resetting member on the rolling shutter cloth 42, so that the rolling shutter cloth 42 is in an unfolded state, blocking between the inner liner 12 and the storage space.

[0059] To further explain, when it is necessary to prevent the cold air in the inner liner 12 from leaking, the rod portion 442 of the rod 44 is pulled from the roller shutter box 41, and the roller shutter 42 is pulled out in the direction of the fixing member; when the rod portion 442 reaches the fixing member, the rod portion 442 is buckled into the fixing member, and the roller shutter 42 blocks the connection between the inner liner 12 and the storage space. When it is necessary to keep the inner liner 12 and the storage space connected, the rod portion 442 of the rod 44 is removed from the fixing member, and the roller shutter 42 is rolled back into the roller shutter box 41 under the action of the reset member.

[0060] Furthermore, the fixing member is installed on an inner wall of one side of the sliding door 3 .

[0061] In another embodiment of the utility model, a fixing piece is provided on the inner wall of one side of the sliding door 3. When the sliding door 3 is in a closed state, the side of the sliding door 3 where the fixing piece is provided contacts the top of the mounting plate 13, and the sliding door 3 and the upper cover 2 together form a space covering the top of the outer shell 11 and the inner liner 12; when the sliding door 3 is pushed upward to flip along the upper cover 2, the bottom of the sliding door 3 moves backward and upward. Therefore, when the pull rod portion 442 of the pull rod 44 is buckled with the fixing member and the sliding door 3 is in a closed state, the rolling curtain 42 is in an expanded state, blocking and separating the inner liner 12 and the storage space inside the refrigerator; when the sliding door 3 is flipped open, the pull rod 44 will drive the rolling curtain 42 to open backward and upward along with the movement of the sliding door 3, and the inner layer blocking structure between the inner liner 12 and the storage space will be removed along with the opening of the sliding door 3; when the sliding door 3 is closed again, the rolling curtain 42 will also move along with the sliding door 3 and expand again, covering and blocking between the inner liner 12 and the storage space. By arranging the fixing member on the inner wall of the movable sliding door 3, the inner layer blocking structure can block or open the connecting space between the inner liner 12 and the storage space along with the opening and closing state of the refrigerator sliding door 3, thereby reducing the operation of opening and closing the inner layer blocking structure.

[0062] It is worth noting that the fixing member can also be arranged on the inner side of the mounting plate 13 or the inner wall of the sliding door 3 at the same time, and the pull rod portion 442 can be snapped into a specific position according to actual use needs.

[0063] Furthermore, the fixing member includes a fixing portion 51 and a clamping groove 52;

[0064] The fixing portion 51 is used for fixing and connecting with the mounting plate 13 or the sliding door 3, and the snap-in groove 52 is used for snap-in connection with the pull rod portion 442;

[0065] The slot opening direction of the clamping slot 52 is away from the shutter box 41 , and the top of the clamping slot 52 is a limiting portion 53 , which is used to limit the pull rod portion 442 from being separated from the clamping slot 52 .

[0066] like Figures 3 to 6 As shown, the fixing member is fixedly mounted on the mounting plate 13 or the inner side of the sliding door 3 through the fixing portion 51, and the clamping groove 52 is used for clamping connection with the pull rod portion 442. The slot opening direction of the clamping groove 52 is away from the shutter box 41, and the pull rod 44 is pulled to the fixing member, and the pull rod portion 442 is put into the clamping groove 52 through the slot opening of the clamping groove 52. Since the reset member of the shutter assembly has the effect of rewinding the shutter cloth 42, the groove wall of the clamping groove 52 and the limiting portion 53 cooperate to limit the pull rod 44 from being separated from the fixing member, thereby limiting the shutter cloth 42 from automatically rewinding back to the shutter box 41.

[0067] By pulling the pull rod 44 toward the slot opening direction of the engaging slot 52 and withdrawing the pull rod 44 from the engaging slot 52 , the locking state between the pull rod 44 and the fixing member can be released. At this time, under the action of the reset member, the rolling curtain 42 will be rolled back to the rolling curtain box 41 .

[0068] Furthermore, the sliding door 3 further comprises a door body 32 and a door body mounting seat 33, wherein the door body mounting seat 33 is mounted on one side of the door body 32, the door body mounting seat 33 is a strip-shaped member, and the door body mounting seat 33 is extended along the length direction of the door body 32, and the hinge shaft 31 is arranged at both ends of the door body 32;

[0069] The door body mounting seat 33 includes a mounting groove 331 and a lifting portion 332 . The mounting groove 331 is used to mount and fix the door body 32 . The front end surface of the mounting groove 331 is bent downward to form the lifting portion 332 .

[0070] like Figures 8 to 10 As shown, the sliding door 3 includes a door body 32 and a door body mounting seat 33 in a right triangle shape, and a mounting groove 331 of the door body mounting seat 33 is used to be mounted and connected with a side edge of the door body 32. The front end surface of the mounting groove 331 is bent downward to form a lifting portion 332, through which the door body 32 can be easily pushed or pulled down to rotate around the hinge shaft 31 to open or close the door.

[0071] It is worth noting that the door body 32 can be made of a transparent material. A refrigerator door made of a transparent material is conducive to displaying items in the refrigerator.

[0072] Furthermore, the door body mounting seat 33 is also provided with a sealing strip groove 333, and the sealing strip groove 333 is arranged on the rear end surface of the mounting groove 331 away from the lifting portion 332. The sealing strip groove 333 extends along the length direction of the door body mounting seat 33, and the sealing strip groove 333 is used to install a sealing strip.

[0073] like Fig.10 As shown, the inner end surface of the door body mounting seat 33 is provided with a sealing strip groove 333 along its length direction, and the sealing strip can be slidably installed in the sealing strip groove 333 through any one end of the openings at both ends of the sealing strip groove 333. After the door body mounting seat 33 is installed with the sealing strip, when the sliding door 3 is in the closed state, the sealing strip abuts against the top surface of the mounting plate 13, and the sealing strip can play a buffering role when the sliding door 3 collides with the mounting plate 13 when closing downward, and can also be used to improve the heat preservation effect of the refrigerator.

[0074] Furthermore, one or more sliding doors 3 are provided, and multiple sliding doors 3 are arranged side by side, and a middle cross beam 14 and a middle vertical beam 15 are provided between two adjacent sliding doors 3, and both ends of the middle cross beam 14 are fixed on the mounting plate 13, and the middle vertical beam 15 is perpendicular to the middle cross beam 14, and both ends of the middle vertical beam 15 are respectively fixed to the upper cover 2 and the middle cross beam 14, and the middle vertical beam 15 is provided with the axial hole.

[0075] refer to Figure 1 , Figure 3 and Figure 4 When there are two sliding doors 3, the two sliding doors 3 are arranged side by side, and a middle vertical beam 15 is arranged between two adjacent sliding doors 3. The middle vertical beam 15 is installed on the middle cross beam 14. Both ends of the middle cross beam 14 are fixed on the mounting plate 13. The middle cross beam 14 provides support for the middle vertical beam 15.

[0076] Specifically, the number of sliding doors 3 can be set according to the size of the refrigerator to avoid a situation where a larger refrigerator is only equipped with one sliding door 3, where a large opening is exposed each time the refrigerator is opened, causing the cold air in the refrigerator to leak out; when the refrigerator is equipped with multiple sliding doors 3, the sliding doors 3 at specific positions can be opened to complete the placement and removal of items, thereby reducing the loss of cold air.

[0077] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
