[0055] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0056] Next, refer to Figures 1 - 10 to describe a door structure provided by an embodiment of the present application. The door structure is applied to a storage device and includes a door shell 100, a door lining 200, and a plurality of mounting members 300.

[0057] It should be noted that the storage device in the embodiment can be understood as a general refrigerated storage device, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, chilled food cabinets, and refrigerated vending machines, etc. The storage device has various structural forms and a wide range of applications. As a specific example, a refrigerator is taken as a specific example in the embodiment of the present application for illustration.

[0058] For the convenience of understanding, the length direction of the door shell 100 is the left - right direction, the width direction of the door shell 100 is the front - back direction, and the height direction of the door shell 100 is the up - down direction.

[0059] The door shell 100 is used to be openably and closably installed on the box body of the storage device, so as to open or close the compartment formed by the box body. In this embodiment, the opening of the compartment faces forward. The door shell 100 has a plurality of corner regions, and the corner regions are located on the side of the door shell 100 close to the box body, and are used to cooperate with the door liner 200 and the door seal to ensure the sealing performance when closing the box body and prevent cold air leakage. Exemplarily, the door shell 100 has four corner regions.

[0060] The door liner 200 is cooperatively connected with the door shell 100 to form a foaming cavity 101, and the door liner 200 protrudes away from the box body to form a mounting portion 210. It should be noted that the size and shape of the foaming cavity 101 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

[0061] It can be understood that the door shell 100 has an assembly opening facing the box body, and the assembly opening is square so that a part of the rear wall surface of the door shell 100 close to the assembly opening can form four corner regions. The door liner 200 overlaps on the rear wall surface of the door shell 100 and covers the assembly opening, and then a foaming cavity 101 is formed between the door liner 200 and the door shell 100. At the same time, the edge of the rear wall surface of the door liner 200 is recessed forward, and the corresponding edge of the front wall surface of the door liner 200 protrudes forward, so that the door liner 200 forms a mounting portion 210 with a receiving groove 220, and the door seal is installed in the receiving groove 220 through the notch of the receiving groove 220 and abuts against the part of the rear wall surface of the door shell 100 close to the assembly opening, thereby further ensuring the sealing performance when closing the box body. It should be noted that the size and shape of each of the receiving grooves 220 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

[0062] The mounting members 300 are located in the foaming cavity 101 and correspond to the corners of the mounting portion 210 one by one. The mounting members 300 are connected to the door shell 100 and jointly form an avoidance groove 400. The outer wall of the mounting portion 210 at the corner is located in the avoidance groove 400 and is spaced apart from the inner wall of the avoidance groove 400. Exemplarily, four mounting members 300 are provided.

[0063] It can be understood that considering that the accommodation groove 220 is in a square ring shape so that the installation part 210 has a plurality of corners corresponding to the corner areas one by one, that is, the part of the accommodation groove 220 corresponding to the corner is a stress concentration point. By connecting the installation part 300 located in the foaming cavity 101 to the wall surface of the corner area of the door shell 100 to form an avoidance groove 400, so that when the door liner 200 is installed on the door shell 100, the corners of the installation part 210 can be located in the avoidance groove 400, thereby playing a circumferential limiting role on the door liner 200, and further enhancing the stability of the entire structure. At the same time, the outer wall of the installation part 210 located in the avoidance groove 400 is spaced apart from the inner wall of the avoidance groove 400 in the corresponding direction, thereby providing space for the overflow of the foaming material, that is, the foaming material can enter the avoidance groove 400 before curing and flow between the outer wall of the installation part 210 and the inner wall of the avoidance groove 400, thereby extending the flow path of the foaming material and reducing the possibility of the foaming material flowing out of the foaming cavity 101 before curing. The cured foaming material in the avoidance groove 400 can also be used to make the connection between the door liner 200 and the door shell 100 more stable.

[0064] In addition, compared with the related art where it is necessary to wrap a sponge strip around the corner area of the door shell 100 and fix it with transparent tape before assembling the door liner 200, by providing an avoidance groove 400 in the corner area and the outer wall of the installation part 210 at the corner being spaced apart from the inner wall of the avoidance groove 400 in the corresponding direction, appropriate space can be reserved for the foaming material, reducing the manual operations required in the manufacturing process, reducing the labor intensity and time cost in the production process, and improving the production efficiency of the door structure.

[0065] According to the door structure provided by the embodiment of the present application, by connecting the installation part 300 located in the foaming cavity 101 to the wall surface of the corner area of the door shell 100 to form an avoidance groove 400, and the outer wall of the installation part 210 of the door liner 200 located at the corner being located in the avoidance groove 400 and being spaced apart from the inner wall of the avoidance groove 400, not only can the foaming material in the foaming cavity 101 enter the avoidance groove 400 before curing and flow between the outer wall of the installation part 210 and the inner wall of the avoidance groove 400, thereby extending the flow path of the foaming material and reducing the possibility of the foaming material flowing out of the foaming cavity 101 before curing, but also the cured foaming material in the avoidance groove 400 can be used to make the connection between the door liner 200 and the door shell 100 more stable, improving the qualification rate of the door structure.

[0066] In some embodiments, such as Figure 3 、 Figure 5 、 Figure 7 and Figure 9 shown, the installation part 300 is provided with a first anti-overflow groove 301, the first anti-overflow groove 301 is located on the groove wall of the avoidance groove 400, and the first anti-overflow groove 301 extends along the direction close to the bottom of the avoidance groove 400.

[0067] It can be understood that by forming the first anti-overflow groove 301 on the groove wall of the avoidance groove 400 in the mounting member 300, not only can the foaming material in the accommodating cavity enter the avoidance groove 400 before curing and the excess foaming material enter the first anti-overflow groove 301, thus extending the flow path and accommodating space of the foaming material and reducing the possibility of the foaming material flowing out of the foaming cavity 101 before curing. At the same time, the first anti-overflow groove 301 extends in the up and down direction, thereby providing a longer anti-overflow path and increasing the interception area when the liquid overflows, so as to more effectively prevent the liquid from flowing out.

[0068] In some embodiments, as Figure 3 , Figure 5 , Figure 7 and Figure 9 shown, a plurality of first anti-overflow grooves 301 may be provided, so as to improve the comprehensiveness of the anti-overflow effect.

[0069] In some embodiments, as Figure 3 , Figure 5 and Figure 7 shown, the plurality of first anti-overflow grooves 301 are arranged at intervals in the front-rear direction, so as to improve the comprehensiveness of the anti-overflow effect. In another embodiment, as Figure 9 shown, a plurality of first anti-overflow grooves 301 may also be arranged at intervals in the left-right direction to improve a more comprehensive anti-overflow effect.

[0070] In this embodiment, as Figure 3 , Figure 5 , Figure 7 and Figure 9 shown, some of the first anti-overflow grooves 301 are located on the inner side wall of the avoidance groove 400 arranged in the left-right direction and close to the outside. Of course, in other embodiments, the first anti-overflow grooves 301 may be provided on both inner side walls of the avoidance groove 400 arranged in the left-right direction, and this embodiment does not make specific restrictions on this. In some embodiments, as Figure 9 shown, some of the first anti-overflow grooves 301 may also be located on the inner wall surface of the avoidance groove 400 arranged in the front-rear direction.

[0071] In some embodiments, as Figure 3 , Figure 5 , Figure 7 and Figure 9 shown, the groove depth of the first anti-overflow groove 301 gradually increases in the direction close to the groove bottom of the avoidance groove 400.

[0072] It can be understood that the depth of each first anti-overflow groove 301 gradually increases from the inside to the outside, which can not only provide a larger contact area, so as to accommodate and store more foaming material, further prevent the foaming material from overflowing, and help guide the foaming material to flow towards the groove bottom of the avoidance groove 400.

[0073] In some embodiments, as Figures 4 - 6 shown, a flow channel 500 is formed on one side of the door shell 100 close to the box body. The flow channel 500 is communicated with the avoidance groove 400, and the flow channel 500 includes at least two flow segments with different flow directions.

[0074] It can be understood that the rear wall surface of the door shell 100 forms the flow channel 500, so as to effectively guide the foaming material to flow from the avoidance groove 400 into the flow channel 500, further extending the flow path of the foaming material and reducing the possibility of the foaming material flowing out of the foaming cavity 101 before curing. At the same time, since the flow channel 500 includes at least two flow segments with different flow directions, it can not only extend the flow path of the foaming material as much as possible in a limited space, but also make the flow direction of the foaming material change when flowing in the flow channel 500, so as to reduce the impact of the foaming material on the inner wall of the flow channel 500 and reduce the possibility of overflow caused by impact and pressure concentration.

[0075] In this embodiment, as Figures 4 - 6 shown, there are four flow segments provided in each flow channel 500. The foaming material in the avoidance groove 400 first moves backward to flow into the flow channel 500, and then first flows outward in the left-right direction in the first flow segment, then flows outward in the up-down direction in the second flow segment, then flows outward in the left-right direction in the third flow segment, and finally flows outward in the up-down direction in the fourth flow segment. Of course, in other embodiments, flow segments with other quantities and flow directions can also be set, and this embodiment does not make specific limitations on this.

[0076] In some embodiments, as Figures 1 - 10 shown, the door shell 100 includes two oppositely arranged decorative strips 110, two oppositely arranged side frames 120 and a panel (not shown). The decorative strips 110 extend in the left-right direction, and mounting members 300 are installed on each decorative strip 110. The surface of each decorative strip 110 close to the other decorative strip 110 forms the bottom of the avoidance groove 400; the two side frames 120 both extend in the up-down direction and are respectively connected to the two decorative strips 110 to form a closed frame; the panel and the door liner 200 are arranged at intervals in the front-back direction, and a foaming cavity 101 is jointly formed among the decorative strips 110, the side frames 120, the panel and the door liner 200.

[0077] It can be understood that the two side frames 120 extend in the up and down direction and are located on the left and right sides of the decorative strip 110, thereby providing vertical stability for the door structure. The two decorative strips 110 extend in the left and right direction and are located on the upper and lower sides of the side frames 120, thereby providing lateral stability for the door structure. The decorative strip 110 and the side frames 120 are connected end to end to form a closed frame with an assembly opening, and the door lining 200 is installed at the rear side of the frame and at the assembly opening. The panel is installed on the front side of the frame, and the two opposite sides of the two side frames 120, the two opposite sides of the two decorative strips 110, and the side of the panel close to the door lining 200 form the inner wall of the foaming cavity 101. At the same time, the connection between the decorative strip 110 and the side frame 120 is defined as a corner area, that is, mounting members 300 are provided at both the left and right ends of the decorative strip 110 to respectively form opposite avoidance grooves 400.

[0078] In this embodiment, as Figures 1 - 10 shown, for the convenience of understanding, a mounting member 300 is provided at the connection between one of the decorative strips 110 and one of the side frames 120. The mounting member 300 is respectively connected to the side of the decorative strip 110 close to the other decorative strip 110 and the side close to the other side frame 120, thereby forming an avoidance groove 400.

[0079] In some embodiments, as Figure 9 and Figure 10 shown, the mounting member 300 includes a first mounting plate 310, a second mounting plate 320, and a third mounting plate 330. The second mounting plate 320 and the third mounting plate 330 are spaced apart. The second mounting plate 320 is disposed inside the first mounting plate 310, and the third mounting plate 330 is disposed outside the first mounting plate 310. Both the first mounting plate 310 and the third mounting plate 330 extend in a direction away from the bottom of the avoidance groove 400 and protrude from the second mounting plate 320.

[0080] It should be noted that the first mounting plate 310 is located in front of the rear wall surface of the door shell 100 and is connected to the side of the decorative strip 110 close to the other decorative strip 110. The second mounting plate 320 and the third mounting plate 330 are respectively disposed on the opposite sides of the first mounting plate 310 in the left and right direction and are both connected to the decorative strip 110. The two opposite sides of the second mounting plate 320 and the third mounting plate 330, the two opposite sides of the first mounting plate 310 and the decorative strip 110, and the side of the decorative strip 110 close to the other decorative strip 110 together form the inner wall of the avoidance groove 400.

[0081] It can be understood that, in the left - right direction, the third mounting plate 330 is located between the second mounting plate 320 and the outer wall of the corresponding connected trim strip 110. And since the first mounting plate 310 and the third mounting plate 330 extend inwards in the up - down direction and protrude from the second mounting plate 320, that is, the lengths of the first mounting plate 310 and the third mounting plate 330 in the up - down direction are both greater than that of the second mounting plate 320. Thus, while avoiding the mounting part 210, it plays a role of partition. That is, after the foaming material enters the avoidance groove 400, on the one hand, it can flow along the second mounting plate 320 in the up - down direction and towards the bottom of the avoidance groove 400. On the other hand, it can flow along the surface of the first mounting plate 310 and then along the surface of the third mounting plate 330 to flow out of the avoidance groove 400 and approach the joint of the trim strip 110 and the side frame 120, so that the foaming material can directly enter the flow channel 500, reducing the overflow of materials and improving the connection stability between the trim strip 110 and the side frame 120 by the curing of the foaming material.

[0082] It should be noted that if the second mounting plate 320 is not provided on the mounting part 300, after the foaming material enters the avoidance groove 400, it is easy to flow along the surface of the first mounting plate 310 and then along the outer wall of the mounting part 210 to flow out of the avoidance groove 400 and approach the part of the trim strip 110 far from the other trim strip 110. Thus, the foaming material is directly exposed outside the rear wall surface of the trim strip 110 after curing, making it difficult to meet the appearance requirements of the door shell 100 and affecting the qualified rate of the product.

[0083] In some embodiments, such as Figure 3 、 Figure 5 and Figure 7 shown, a plurality of first anti - overflow grooves 301 are arranged at intervals in the front - rear direction on the third mounting plate 330. In other embodiments, such as Figure 9 shown, a part of the first anti - overflow grooves 301 are arranged at intervals in the front - rear direction on the third mounting plate 330, and another part of the first anti - overflow grooves 301 are arranged at intervals in the left - right direction on the first mounting plate 310.

[0084] In some embodiments, such as Figure 9 shown, the side of the second mounting plate 320 away from the bottom of the avoidance groove 400 includes a flat section 321 and a curved section 322. One side of the flat section 321 forms a continuous plane with the wall surface of the door shell 100; one side of the curved section 322 is connected to the other side of the flat section 321, and the curved section 322 and the side of the first mounting plate 310 close to the box body are smoothly and transitionally connected.

[0085] It can be understood that the second mounting plate 320 is arranged in the up-down direction and the inner surface thereof includes a flat section 321 and an arc section 322 that are connected in sequence from the rear to the front. The rear side of the flat section 321 and the surface of the decorative strip 110 close to the other decorative strip 110 form a continuous flat surface, enhancing the overall stability of the door structure while reducing the possibility of the foaming material flowing out of the avoidance groove 400 from the connection between the flat section 321 and the decorative strip 110; the front side of the arc section 322 is smoothly connected to the middle of the inner edge of the rear surface of the first mounting plate 310, thereby helping to maintain the overall strength of the mounting member 300 and guiding the foaming material to flow into the avoidance groove 400 from the connection between the arc section 322 and the first mounting plate 310, and also helping to reduce the accumulation or poor flow of the foaming material at the connection.

[0086] In some embodiments, such as Figure 8 and Figure 9 shown, the mounting member 300 further includes at least one partition plate 340. The partition plate 340 is connected to the door shell 100 and the first mounting plate 310 respectively, and the partition plate 340 is located between the second mounting plate 320 and the third mounting plate 330, and the partition plate 340 is adapted to be in abutting cooperation with the outer wall of the mounting portion 210. It should be noted that the shape and size of the partition plate 340 can be designed according to actual needs, and this embodiment does not make specific limitations thereto.

[0087] It can be understood that the front and rear surfaces of the partition plate 340 are respectively connected to the two surfaces of the first mounting plate 310 and the decorative strip 110 that are close to each other in the front-rear direction. One end of the partition plate 340 is connected to the bottom of the avoidance groove 400, and the other end extends inward in the up-down direction and abuts against the outer wall of the mounting portion 210, which not only plays a role in supporting and positioning the mounting portion 210, but also plays a role in distributing the flow of the foaming material in the avoidance groove 400, improving the overall strength of the mounting member 300 and the sealing performance of the door structure.

[0088] In some embodiments, such as Figure 8 and Figure 9 shown, at least two partition plates 340 are arranged at intervals in the left-right direction in the avoidance groove 400, which not only improves the support strength and positioning accuracy of the mounting portion 210, but also improves the uniformity of the flow of the foaming material in the avoidance groove 400, increasing the overall strength of the mounting member 300 and the sealing performance of the door structure. It should be noted that the shapes and sizes between the partition plates 340 can be different, as long as it can be ensured that each partition plate 340 can abut against the outer wall of the mounting portion 210, and this embodiment does not make specific limitations thereto.

[0089] In some embodiments, such as Figures 4 - 9As shown, the trim strip 110 is convexly provided with a mating portion 111 at the edge of the avoidance groove 400, and at least a part of the mating portion 111 extends in a direction close to another trim strip 110. The side frame 120 overlaps with the trim strip 110, and the two sides of the side frame 120 and the mating portion 111 that are close to each other are spaced apart to form a flow channel 500.

[0090] It can be understood that an effective flow channel 500 is formed through the overlapping fit between the side frame 120 and the trim strip 110 and the extending direction of the mating portion 111. A part of the mating portion 111 on one trim strip 110 extends in the up and down direction towards another trim strip 110 to connect the avoidance groove 400 and the flow channel 500. Another part of the mating portion 111 on one trim strip 110 extends in the left and right direction towards the adjacent side frame 120, so as to extend the length of the flow channel 500 as much as possible. At the same time, the convex setting of the mating portion 111 can also enhance the connection strength between the trim strip 110 and the side frame 120, improve the stability of the door shell 100, and effectively utilize the space to naturally form a flow channel 500 convenient for the flow of foaming material.

[0091] In some embodiments, as Figures 4 - 6 shown, along the direction away from another trim strip 110, the distance between the surface of the mating portion 111 close to the side frame 120 and the surface of the corresponding side frame 120 away from another side frame 120 does not decrease monotonically.

[0092] It can be understood that from top to bottom, the distance between the surface of the upper mating portion 111 close to the right side frame 120 and the right side surface of the right side frame 120 does not decrease monotonically, and the distance between the surface of the upper mating portion 111 close to the left side frame 120 and the left side surface of the left side frame 120 does not decrease monotonically, so that the corresponding flow channel 500 includes at least two flow segments with different flow directions. Similarly, from bottom to top, the distance between the surface of the lower mating portion 111 close to the right side frame 120 and the right side surface of the right side frame 120 does not decrease monotonically, and the distance between the surface of the lower mating portion 111 close to the left side frame 120 and the left side surface of the left side frame 120 does not decrease monotonically, so that the corresponding flow channel 500 includes at least two flow segments with different flow directions.

[0093] In some embodiments, as Figure 7 and Figure 8 shown, the trim strip 110 is provided with a second anti-overflow groove 112, and the projections of the second anti-overflow groove 112 in the up and down direction and the left and right direction are respectively located within the projections of the side frame 120 in the up and down direction and the left and right direction.

[0094] It is understandable that, considering the overlap between the decorative strip 110 and the side frame 120, by providing the second anti-overflow groove 112 at the left and right ends of the decorative strip 110, it is helpful to provide additional anti-overflow protection for the foam material overflowing from the flow channel 500. At the same time, since the projection of the second anti-overflow groove 112 in the up-down direction is located within the projection of the side frame 120 in the up-down direction, and the projection of the second anti-overflow groove 112 in the left-right direction is respectively located within the projection of the side frame 120 in the left-right direction, the limited space can be more effectively utilized, and the foam material can be prevented from flowing to the exposed rear wall surface of the decorative strip 110 and the exposed rear wall surface of the side frame 120 as much as possible, and the stability of the connection between the side frame 120 and the decorative strip 110 is further ensured by the solidified foam material.

[0095] In some embodiments, Figures 7 - 9 As shown, a plurality of second anti-overflow grooves 112 may be provided, and the plurality of second anti-overflow grooves 112 are spaced apart in the up-down direction, thereby further improving a more comprehensive anti-overflow effect.

[0096] In some embodiments, Figures 4 - 8 As shown, one of the decorative strip 110 and the side frame 120 is provided with a limiting protrusion 113, and the other of the decorative strip 110 and the side frame 120 is provided with a limiting groove 121, and the limiting protrusion 113 and the limiting groove 121 match each other.

[0097] It can be understood that by respectively providing matching limiting protrusions 113 and limiting grooves 121 on the trim 110 and the side frame 120, a limiting function is added on the basis of the overlapping fit of the trim 110 and the side frame 120, thereby ensuring the precise alignment of the trim 110 and the side frame 120 during assembly, improving the overall stability of the door shell 100, and increasing the contact points between the trim 110 and the side frame 120, thereby enhancing the strength of the door shell 100.

[0098] In this embodiment, the limiting groove 121 is set on the decorative strip 110, and the limiting groove 121 is set on the side frame 120. Of course, in other embodiments, the limiting groove 121 can also be set on the side frame 120, and the limiting groove 121 can be set on the decorative strip 110, and this embodiment does not make specific restrictions on this.

[0099] The embodiment of the present application further provides a storage device, which includes a box body and the above-mentioned door structure, wherein the box body forms a compartment, and the door structure is installed on the box body in an openable and closable manner to seal the compartment.

[0100] It should be noted that the storage device in the embodiments can be understood as a general refrigerated storage device, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, fresh food cabinets, and refrigerated vending machines, etc. The storage device has various structural forms and a wide range of applications.
