[0044] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the 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 drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0045] Reference will be made below to Figures 1 - 8 Describe the door structure provided by the embodiment of the present application. The door structure is applied to a storage device and includes a door shell 110, a door liner 120 and a mounting member 130.

[0046] 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, cold fresh cabinets, and refrigerated vending machines, etc. The storage device has a variety of structural forms and a wide range of applications. As a specific example, a vertical freezer is taken as a specific example in the embodiment of the present application for illustration.

[0047] For the convenience of understanding, the length direction of the door shell 110 is the left-right direction, the width direction of the door shell 110 is the front-back direction, and the height direction of the door shell 110 is the up-down direction.

[0048] The door shell 110 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 110 has a plurality of corner regions, which are located on the side of the door shell 110 close to the box body and are used to cooperate with the door liner 120 and the door seal 140 to ensure the sealing performance when the box body is closed and prevent cold air leakage.

[0049] The door liner 120 is cooperatively connected with the door shell 110 to form an accommodation cavity 111, and the door liner 120 protrudes away from the box body to form a mounting portion 121. It should be noted that the size and shape of the accommodation cavity 111 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

[0050] It can be understood that the door shell 110 has an assembly opening facing the box body. The assembly opening is square so that four corner regions can be formed at the part of the rear wall surface of the door shell 110 close to the assembly opening. The door liner 120 overlaps the rear wall surface of the door shell 110 and covers the assembly opening, and thus an accommodation cavity 111 is formed between the door liner 120 and the door shell 110. At the same time, the edge of the rear wall surface of the door liner 120 is recessed forward, and the corresponding edge of the front wall surface of the door liner 120 protrudes forward, so that the door liner 120 forms a mounting portion 121 with a receiving groove 122, and the door seal 140 is installed in the receiving groove 122 through the notch of the receiving groove 122 and abuts against the part of the rear wall surface of the door shell 110 close to the assembly opening, thereby further ensuring the sealing performance when the box body is closed. It should be noted that the size and shape of the receiving groove 122 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

[0051] A plurality of mounting members 130 correspond to the corner regions one by one. The mounting members 130 are located in the accommodation cavity 111. The mounting members 130 are installed in the corner regions and form an avoidance groove 131 with the door shell 110. The avoidance groove 131 is used to support the corner of the mounting portion 121, and the groove wall of the avoidance groove 131 forms a plurality of flow channels 132. Exemplarily, four mounting members 130 are provided.

[0052] It can be understood that, considering that the accommodation groove 122 is in a square ring shape, that is, the corners of the accommodation groove 122 are stress concentration points. By connecting the mounting member 130 located in the accommodation cavity 111 to the wall surface of the corner area of the door shell 110 to form an avoidance groove 131 with three open sides, so that when the door liner 120 is installed on the door shell 110, the corners of the installation part 121 can be located in the avoidance groove 131, thereby enhancing the stability of the entire structure. At the same time, by forming a plurality of flow channels 132 on the groove wall of the avoidance groove 131, it is not only convenient for the foaming material in the accommodation cavity 111 to enter the avoidance groove 131 and flow along the flow channels 132 before curing, thus extending the flow path of the foaming material and reducing the possibility of the foaming material flowing out of the accommodation cavity 111 before curing, but also the foaming material cured in the avoidance groove 131 can make the connection between the door liner 120 and the door shell 110 more stable.

[0053] In addition, compared with the related art where it is necessary to wind a sponge strip around the corner area of the door shell 110 and fix it with transparent tape before assembling the door liner 120, by setting the avoidance groove 131 in the corner area and the outer wall of the installation part 121 at the corner being located in the avoidance groove 131, and forming a plurality of flow channels 132 on the groove wall of the avoidance groove 131 to reserve appropriate space for the foaming material, the manual operation required for the manufacturing process is reduced, the labor intensity and time cost in the production process are reduced, and the production efficiency of the door structure is improved.

[0054] According to the door structure provided by the embodiment of the present application, by setting the mounting member 130 located in the accommodation cavity 111 to be connected to the wall surface of the corner area of the door shell 110 to form the avoidance groove 131, and forming a plurality of flow channels 132 on the groove wall of the avoidance groove 131, it is not only convenient for the foaming material in the accommodation cavity 111 to enter the avoidance groove 131 and flow along the flow channels 132 before curing, thus extending the flow path of the foaming material and reducing the possibility of the foaming material flowing out of the accommodation cavity 111 before curing, but also the foaming material cured in the avoidance groove 131 can make the connection between the door liner 120 and the door shell 110 more stable, and the qualified rate of the door structure is improved.

[0055] In some embodiments, as Figure 6 and Figure 7 shown, the flow channel 132 includes two straight flow sections 1321 and a bent flow section 1322. The straight flow sections 1321 extend in a direction away from the box body; both ends of the bent flow section 1322 are connected to the ends of the two straight flow sections 1321 away from the box body. It should be noted that the lengths and shapes of the straight flow sections 1321 and the bent flow section 1322 can be designed according to actual needs, and the present embodiment does not make specific limitations on this.

[0056] It can be understood that the two straight flow segments 1321 extend in the front-rear direction, which helps to guide the foaming material into and out of the avoidance groove 131, reducing the resistance and dispersion of the foaming material during the flow process; the curved flow segment 1322 is located between the two straight flow segments 1321 and is connected to the front end of the straight flow segment 1321. The design of the curved flow segment 1322 can increase the path length of the flow channel 132, which helps to control the flow velocity and pressure of the foaming material. At the same time, it can also serve as an adjustment point for the flow direction of the foaming material to ensure that the material can be evenly filled into the avoidance groove 131.

[0057] In this embodiment, as Figure 6 and Figure 7 shown, the center of curvature of the curved flow segment 1322 is located outside the curved flow segment 1322.

[0058] It can be understood that the center of curvature is outside the curved flow segment 1322, that is, the center of curvature of the curved flow segment 1322 is located between the corresponding corner of the inner side wall of the door shell 110 and the curved flow segment 1322, so that the foaming material flows more smoothly in the flow channel 132, which helps to reduce the turbulence and eddy current of the foaming material during the flow process, and reduce the accumulation of the foaming material at the bend, thus avoiding the phenomenon of uneven foaming or blockage caused by the accumulation of the foaming material.

[0059] In some embodiments, as Figure 3 、 Figure 6 and Figure 7 shown, the depths of the multiple curved flow segments 1322 gradually decrease from the outside to the inside.

[0060] It can be understood that from the outside to the inside, the depth of the curved flow segment 1322 gradually decreases. That is, when the foaming material in the accommodation cavity 111 flows from the inside to the outside, since the depths of the curved flow segments 1322 passed through in sequence gradually increase, it not only helps to control the flow velocity of the foaming material, but also can buffer the impact force when the foaming material flows outwards, further reducing the possibility of overflow.

[0061] In some embodiments, as Figure 3 、 Figure 6 and Figure 7 shown, the groove wall of the avoidance groove 131 has a first wall surface 1311, a second wall surface 1312 and a third wall surface 1313 that are connected to each other. The second wall surface 1312 faces the box body. The two straight flow segments 1321 of each flow channel 132 are respectively located on the first wall surface 1311 and the third wall surface 1313, and the curved flow segment 1322 is located on the second wall surface 1312.

[0062] It can be understood that the groove walls of the three-sided open relief groove 131 are formed by the mutually connected first wall surface 1311, second wall surface 1312, and third wall surface 1313. The second wall surface 1312 is perpendicular to the front-rear direction, the first wall surface 1311 is perpendicular to the left-right direction, and the third wall surface 1313 is perpendicular to the up-down direction. Thus, the foaming material in the accommodation cavity 111 first flows into the curved flow section 1322 on the second wall surface 1312, then flows into the straight flow sections 1321 on the first wall surface 1311 and the third wall surface 1313 respectively, and finally the foaming material in the straight flow sections 1321 on the first wall surface 1311 and the third wall surface 1313 all flows backward out of the relief groove 131. Furthermore, a clear flow boundary is provided for the foaming material, ensuring stability between the installation part 121 and the installation member 130 during the foaming process, and reducing deformation and overflow caused by foaming pressure.

[0063] In some embodiments, as Figure 3 、 Figure 5 and Figure 6 shown, the depth of the straight flow section 1321 gradually increases in the direction away from the box body.

[0064] It can be understood that the depth of each straight flow section 1321 gradually increases from the rear to the front. That is, when the foaming material flows from the second wall surface 1312 into the first wall surface 1311 or the third wall surface 1313, the relief groove 131 can be filled more gradually, which helps to reduce the situation of excessive accumulation or overflow of the foaming material in the initial filling stage. At the same time, the gradual change in the depth of the straight flow section 1321 can also optimize the foaming effect, enabling the foaming material to form a more uniform and continuous heat insulation layer during the curing process, precisely controlling the flow and distribution of the foaming material, and reducing material waste.

[0065] In some embodiments, as Figure 6 and Figure 7 shown, a plurality of ribs 1301 are provided on the side of the installation member 130 close to the box body. A flow channel 132 is formed between two adjacent ribs 1301, and both ends of the rib 1301 extend in the direction close to the box body to be connected to the door shell 110.

[0066] It can be understood that by providing ribs 1301 on the rear wall surface of the installation member 130 and extending both ends of the rib 1301 to the wall surface of the door shell 110 close to the assembly port, not only can the required flow channel 132 be formed on the groove wall of the relief groove 131, but also the stability of the entire installation member 130 can be further enhanced, and the support strength for the door liner 120 can be improved.

[0067] In this embodiment, as Figure 3 、 Figure 5 and Figure 6As shown, from back to front, the thickness of the rib portions 1301 located on the first wall surface 1311 and the third wall surface 1313 gradually increases to achieve a gradually increasing depth of the straight flow section 1321; from outside to inside, the thickness of the rib portions of the multiple ribs 1301 located on the second wall surface 1312 gradually decreases to achieve a gradually decreasing depth of the multiple curved flow sections 1322 from outside to inside.

[0068] In some embodiments, as Figures 1 to 8 shown, the door shell 110 includes two oppositely arranged side frames 1101, two oppositely arranged decorative strips 1102, and a panel 1103. The side frames 1101 extend vertically; the decorative strips 1102 extend in the left - right direction and are respectively connected to the two decorative strips 1102 to form a closed frame. Mounting members 130 are installed on each decorative strip 1102; the panel 1103 and the door lining 120 are spaced apart in the front - back direction. A receiving cavity 111 is jointly formed among the decorative strips 1102, the side frames 1101, the panel 1103, and the door lining 120.

[0069] It can be understood that the two side frames 1101 extend in the up - down direction and are located on the left and right sides of the decorative strips 1102, thus providing vertical stability for the door structure. The two decorative strips 1102 extend in the left - right direction and are located on the upper and lower sides of the side frames 1101, thus providing lateral stability for the door structure. The decorative strips 1102 and the side frames 1101 are connected end - to - end to form a closed frame with an assembly opening. The door lining 120 is installed at the rear of the frame and at the assembly opening. The panel 1103 is installed at the front of the frame, and the inner walls of the receiving cavity 111 are formed by the two adjacent sides of the two side frames 1101, the two adjacent sides of the two decorative strips 1102, and the side of the panel 1103 close to the door lining 120. At the same time, the connection between the decorative strip 1102 and the side frame 1101 is defined as a corner area, that is, mounting members 130 are provided at both the left and right ends of the decorative strip 1102 to respectively form opposite avoidance grooves 131.

[0070] In this embodiment, as Figures 1 to 8 shown, for the convenience of understanding, a mounting member 130 is provided at the connection between one of the decorative strips 1102 and one of the side frames 1101. The mounting member 130 is respectively connected to the side of the decorative strip 1102 close to the other decorative strip 1102 and the side close to the other side frame 1101, thereby forming an avoidance groove 131.

[0071] In some embodiments, as Figure 4 、 Figure 5 and Figure 7As shown, at both ends of the decorative strip 1102 in the left - right direction, a plurality of anti - overflow grooves 11021 are formed at intervals in the up - down direction. The outer wall surface of the decorative strip 1102 near the notch of the anti - overflow groove 11021 is attached to the inner wall surface of the side frame 1101. It should be noted that the number and size of the anti - overflow grooves 11021 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

[0072] It can be understood that a plurality of anti - overflow grooves 11021 are formed at both ends of the decorative strip 1102 in the left - right direction at intervals in the up - down direction, so that they can serve as discharge channels for the excess foaming material to flow from the relief groove 131 to the rear wall surface of the decorative strip 1102 during the foaming process, which helps to reduce the accumulation of foaming material outside the accommodating cavity 111 and improve production efficiency. At the same time, since the outer wall surface of the decorative strip 1102 near the notch of the anti - overflow groove 11021 is attached to the inner wall surface of the side frame 1101, it not only helps to ensure the structural stability of the door shell 110, but also prevents the foaming material from overflowing from the anti - overflow groove 11021 to the rear wall surface of the side frame 1101 and the rear wall surface of the decorative strip 1102, avoiding the foaming material being exposed on the rear wall surface of the door shell 110 around the assembly opening after curing.

[0073] In some embodiments, as Figure 4 、 Figure 5 and Figure 7 shown, from the outside to the inside, the groove depths of the plurality of anti - overflow grooves 11021 gradually decrease from the outside to the inside.

[0074] It can be understood that the groove depths of the plurality of anti - overflow grooves 11021 of the upper decorative strip 1102 gradually increase from bottom to top, and the groove depths of the plurality of anti - overflow grooves 11021 of the lower decorative strip 1102 gradually increase from top to bottom. This not only helps to control the flow rate of the foaming material, but also can buffer the impact force when the foaming material overflowing from the relief groove 131 flows outwards, further reducing the possibility of overflow.

[0075] In some embodiments, as Figure 4 、 Figure 5 and Figure 7 shown, the width of the anti - overflow groove 11021 gradually increases from the inside to the outside.

[0076] It can be understood that the part of the anti - overflow groove 11021 close to the box body extends in the left - right direction. The widths of the anti - overflow grooves 11021 at the left end of the decorative strip 1102 gradually increase from right to left, and the widths of the anti - overflow grooves 11021 at the right end of the decorative strip 1102 gradually increase from left to right. This can more effectively collect the foaming material overflowing from the accommodating cavity 111, helps to reduce the pressure of the foaming material flowing in the anti - overflow groove 11021, and reduces the risk of the foaming material flowing back or overflowing.

[0077] An embodiment of the present application further provides a storage device. The storage device includes a box body and the above-mentioned door structure. The box body forms a compartment; the door structure is detachably installed on the box body for closing the compartment. It should be noted that the size and shape of the compartment can be designed according to actual needs, and this embodiment does not make specific limitations thereto. In this embodiment, the opening of the compartment faces forward.

[0078] It should be noted that the storage device in the embodiment can be understood as a generalized refrigerated storage device, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold fresh cabinets, and refrigerated vending machines, etc. The storage device has various structural forms and a wide range of applications.

[0079] According to the storage device provided by the embodiment of the present application, by providing a mounting member 130 located in the accommodating cavity 111 in the door structure and connecting it to the wall surface of the corner area of the door shell 110 to form an avoidance groove 131, and multiple flow channels 132 are formed on the groove wall of the avoidance groove 131, it is not only convenient for the foaming material in the accommodating cavity 111 to enter the avoidance groove 131 and flow along the flow channels 132 before curing, thereby extending the flow path of the foaming material and reducing the possibility of the foaming material flowing out of the accommodating cavity 111 before curing, but also the cured foaming material in the avoidance groove 131 can make the connection between the door liner 120 and the door shell 110 more stable, improving the qualification rate of the door structure.
