Description

Technical Field

[0001] This application belongs to the technical field of refrigeration, and particularly relates to a door structure and a storage device. Background Art

[0002] Whether it is a freezer or a refrigerator, they are household appliances that store items at a low temperature to maintain their freshness. Due to the significant temperature difference between the inside and outside and the relatively weak structure at the handle installation on the door body, the door body is prone to deformation. This deformation not only affects the sealing performance of the refrigerator but also causes cold air leakage, thereby increasing the energy consumption of the refrigerator. At the same time, the temperature difference at the deformed part of the door body may also cause frosting, further exacerbating the energy consumption problem. In severe cases, it may even affect the normal use of the refrigerator, resulting in a decline in user experience. Summary of the Utility Model

[0003] This application aims to solve at least one of the technical problems existing in the prior art. For this purpose, this application provides a door structure and a storage device.

[0056] The embodiments of the present application will be described in detail below. The 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.

[0057] Reference will be made below to Figures 1 - 8 to describe the door structure provided by the embodiments of the present application. This door structure is applied to a storage device, and the door structure includes a door body 100, a first reinforcing member 700, and a second reinforcing member 800.

[0058] 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, cold fresh cabinets, and refrigerated vending machines, etc. The storage device has various structural forms and a wide range of applications. As a specific example, a vertical freezer is taken as a specific example in the embodiments of the present application for illustration.

[0059] For the convenience of understanding, the length direction of the door body 100 is the left - right direction, the width direction of the door body 100 is the front - back direction, and the height direction of the door body 100 is the up - down direction.

[0060] The door body 100 is used to be installed on the box body of the storage device in an openable and closable manner, 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 body 100 forms a receiving cavity 111, and the door body 100 is provided with a handle 200. It should be noted that the size and shape of the receiving cavity 111 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

[0061] It can be understood that the handle 200 facilitates the user to open and close the door body 100. The door body 100 includes a door shell 110, a door lining 120 and a door seal 140. The door shell 110 is installed on the box body in an openable and closable manner and has an assembly opening facing the box body. The door lining 120 overlaps the rear wall surface of the door shell 110 and covers the assembly opening, and thus a receiving cavity 111 is formed between the door lining 120 and the door shell 110. The edge of the rear wall surface of the door lining 120 is recessed forward, and the corresponding edge of the front wall surface of the door lining 120 protrudes forward, so that the door lining 120 forms an installation part with a receiving groove, and the door seal 140 is installed in the receiving groove through the notch of the receiving groove and abuts against a part of the rear wall surface of the door shell 110 close to the assembly opening, thereby ensuring the sealing performance when the box body is closed.

[0062] The first reinforcing member 700 is arranged in the receiving cavity 111, and the first reinforcing member 700 is located on the side of the door body 100 close to the handle 200. The first reinforcing member 700 forms a first through groove 701, and the notch of the first through groove 701 is arranged in a direction away from the handle 200.

[0063] It should be noted that the door shell 110 includes two relatively arranged side frames 1101, two relatively 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; the panel 1103 and the door lining 120 are arranged at intervals in the front - rear direction. The decorative strips 1102, the side frames 1101, the panel 1103 and the door lining 120 jointly form the receiving cavity 111, and both the handle 200 and the first reinforcing member 700 are arranged close to the same side frame 1101.

[0064] It can be understood that considering that the side of the door body 100 with the handle 200 installed is weaker in strength than the rest of the door body 100, so by arranging the first reinforcing member 700 near the handle 200, the structural strength of the door body 100 can be enhanced, and the possibility of the door body 100 deforming can be reduced. At the same time, since the notch of the first reinforcing member 700 is away from the handle 200, it helps to form a structure with uniformly distributed stress inside the door body 100, reduce the deformation caused by local stress concentration, and can counteract the bending or torsional force generated when using the handle 200, which helps to reduce the possibility of the door body 100 deforming under various usage conditions, thereby improving the durability and reliability of the storage device.

[0065] The second reinforcing member 800 is disposed within the accommodating cavity 111, and the second reinforcing member 800 is located on the side of the door body 100 away from the handle 200. The second reinforcing member 800 forms a second through groove 802, and the notch of the second through groove 802 is arranged facing the direction of the cabinet body.

[0066] It can be understood that considering that the side of the door body 100 away from the handle 200 is usually pivotally connected to the cabinet body, that is, the location of the center of gravity of the door body 100, setting the second reinforcing member 800 helps to provide additional support for the door body 100 and reduce bending or twisting generated when opening and closing the door body 100. At the same time, since the notch of the second through groove 802 formed by the second reinforcing member 800 faces the cabinet body, it helps to more effectively distribute the stress near the pivot side of the door body 100, reduce local stress concentration, and thus improve the durability and reliability of the storage device.

[0067] According to the door structure provided by the embodiment of the present application, by arranging the first reinforcing member 700 on the side of the door body 100 close to the handle 200, and arranging the second reinforcing member 800 on the side of the door body 100 away from the handle 200, and cooperating with the notch of the first through groove 701 formed by the first reinforcing member 700 being away from the handle 200 and the notch of the second through groove 802 formed by the second reinforcing member 800 being close to the cabinet body, it helps to form a structure with evenly distributed stress inside the door body 100, reduce the possibility of deformation of the door body 100 under various usage conditions, and thus improve the durability and reliability of the storage device.

[0068] In some embodiments, such as Figure 1 and Figure 2 as shown, the handle 200 is arranged on the side wall of the door body 100 in the left - right direction. The first reinforcing member 700 and the second reinforcing member 800 are arranged at intervals in the left - right direction, and both the first reinforcing member 700 and the second reinforcing member 800 extend in the up - down direction.

[0069] It can be understood that by arranging the handle 200 on the side frame 1101, compared with arranging the handle 200 on the panel 1103, not only can the space in the panel 1103 area be saved, enabling the panel 1103 to have interactive, display, advertising or other functional designs, but also it is more ergonomic and can provide a more natural holding position. At the same time, the first reinforcing member 700 and the second reinforcing member 800 are arranged at intervals in the left - right direction, which helps to enhance the lateral stability of the door body 100 and resist lateral bending or twisting. Coupled with the fact that both the first reinforcing member 700 and the second reinforcing member 800 extend in the up - down direction, it can thus provide continuous reinforcement for the door body 100, helping to resist vertical loads and maintain the flatness of the door body 100.

[0070] In this embodiment, the handle 200 is disposed on the left side frame 1101 of the door body 100. The second reinforcing member 800 is located in the accommodating cavity 111 and is disposed close to the right side frame 1101. The first through groove 701 formed by the first reinforcing member 700 extends in the up and down direction, and the notch of the first through groove 701 faces right. The second reinforcing member 800 is located in the accommodating cavity 111 and is disposed close to the right side frame 1101. The second through groove 802 formed by the second reinforcing member 800 extends in the up and down direction, and the notch of the second through groove 802 faces backward.

[0071] In some embodiments, as Figures 3 to 6 shown, the first reinforcing member 700 includes a first section 710, a second section 720, and a third section 730. The surface of the first section 710 facing the handle 200 is attached to the inner wall of the accommodating cavity 111, and the first section 710 forms a first groove section 711. The second section 720 is spaced from the first section 710, the surface of the second section 720 facing the handle 200 is attached to the inner wall of the accommodating cavity 111, and the second section 720 forms a second groove section 721. The third section 730 is connected to the first section 710 and the second section 720 at an angle respectively. The third section 730 forms a third groove section 731. Along the notch direction of the first through groove 701, both the first section 710 and the third section 730 are located between the third section 730 and the handle 200. Among them, the first through groove 701 includes the first groove section 711, the third groove section 731, and the second groove section 721 that are connected to each other.

[0072] It can be understood that, from top to bottom, the first section 710, the third section 730, and the second section 720 are connected in sequence. At the same time, the first groove section 711 formed by the first section 710, the third groove section 731 formed by the third section 730, and the second groove section 721 formed by the second section 720 are connected in sequence to form the first through groove 701. The surfaces of the first section 710 and the second section 720 that are away from the notch of the first through groove 701 are attached and connected to the inner left wall of the accommodating cavity 111 (i.e., the right wall surface of the left side frame 1101), which helps to strengthen the structure of the door body 100 and reduce deformation when the door body 100 is subjected to external forces. The upper end and the lower end of the third section 730 are respectively connected to the lower end of the first section 710 and the upper end of the second section 720 at an angle to avoid the part of the handle 200 disposed in the door body 100, and at the same time, it also helps to disperse and transmit the stress received by the door body 100.

[0073] In some embodiments, as Figures 2 to 4 、 Figure 6 shown, the third section 730 is smoothly and transitionally connected to the first section 710 and the second section 720 respectively, which helps to distribute the stress more evenly, reduce the stress concentration near the connection part, thereby reducing the risk of fracture or damage, and improving the ability to bear bending or torsional loads.

[0074] In some embodiments, asFigure 3 and Figure 4 As shown in Figure 4 , along the notch direction of the second through groove 802, the projection of the handle 200 is located between the projections of the first section 710 and the second section 720.

[0075] It can be understood that the projection of the handle 200 in the front-back direction is located between the projections of the first section 710 and the second section 720 in the front-back direction, and the third section is located between the second section 720 and the handle 200, so that the handle 200 is in the space surrounded by the first section 710, the second section 720, the third section 730 and the inner left side wall of the accommodating cavity 111, which helps to ensure the compactness of the structure inside the door body 100 while maintaining the stability of the entire door structure, and reduces the occurrence of the door body 100 being distorted or bent due to the force at the handle 200.

[0076] In some embodiments, as Figures 4 to 6 shown in Figures 4 to 6 , the first reinforcing member 700 further includes a first flanging 740, the first flanging 740 is arranged at the notch of the first groove section 711 and extends along the direction close to the box body, and the surface of the first flanging 740 facing the handle 200 is attached to the inner wall of the accommodating cavity 111.

[0077] It can be understood that the part of the right wall surface of the first section 710 close to the rear wall surface of the first section 710 is connected to the left wall surface at the front of the first flanging 740, and makes the first flanging 740 extend backward and at least part of its left wall surface is attached to the inner left side wall of the accommodating cavity 111, which can not only provide additional edge support for the first section 710 and the door body 100 respectively, enhance the overall strength and torsional resistance of the structure, help to more evenly distribute the stress transmitted through the notch of the first groove section 711, reduce local stress concentration, and thus improve the durability of the door body 100.

[0078] In some embodiments, as Figure 4 shown in Figure 4 , the first reinforcing member 700 further includes a second flanging 750, the second flanging 750 is arranged at the notch of the second groove section 721 and extends along the direction close to the box body, and the surface of the second flanging 750 facing the handle 200 is attached to the inner wall of the accommodating cavity 111.

[0079] It can be understood that the part of the right wall surface of the second section 720 close to the rear wall surface of the second section 720 is connected to the left wall surface at the front of the second flanging 750, and makes the second flanging 750 extend backward and at least part of its left wall surface is attached to the inner left side wall of the accommodating cavity 111, which can not only provide additional edge support for the second section 720 and the door body 100 respectively, enhance the overall strength and torsional resistance of the structure, help to more evenly distribute the stress transmitted through the notch of the second groove section 721, reduce local stress concentration, and thus improve the durability of the door body 100.

[0080] In this embodiment, the first flanging 740 and the second flanging 750 are respectively arranged at the notches corresponding to the first groove section 711 and the second groove section 721. Of course, in other embodiments, the first flanging 740 may be arranged only at the notch of the first groove section 711 or the second flanging 750 may be arranged at the notch of the second groove section 721. This embodiment does not make specific restrictions on this.

[0081] In some embodiments, such as Figure 4 and Figure 6 shown, the first reinforcing member 700 further includes a third flanging 760. The third flanging 760 is arranged at the notch of the third groove section 731 and is located on the side close to the box body, and extends along the direction away from the handle 200.

[0082] It can be understood that the part of the right wall surface of the third section 730 close to the rear wall surface of the third section 730 is connected to the left wall surface of the third flanging 760. The rear wall surface of the third flanging 760 and the rear wall surface of the third section 730 are continuous planes, which helps to maintain the consistency and stability of the overall structure of the first reinforcing member 700. Considering that the handle 200 is arranged on the left side of the third section 730, by connecting the third flanging 760 to the third section 730 and extending it to the right, additional support is provided near the handle 200, which helps to enhance the bending resistance of the door body 100 at the handle 200.

[0083] In some embodiments, such as Figure 7 shown, the second reinforcing member 800 includes a first plate 810, a second plate 820 and a third plate 830. The surface of the first plate 810 away from the handle 200 is attached to the inner wall of the accommodating cavity 111; the second plate 820 is arranged at an interval from the first plate 810, and the width of the second plate 820 is smaller than the width of the first plate 810; the third plate 830 is respectively connected to the first plate 810 and the second plate 820 and encloses to form a second through groove 802. The surface of the third plate 830 away from the box body is attached to the inner wall of the accommodating cavity 111.

[0084] It can be understood that the right wall surface of the first plate 810 is attached to the inner right side wall of the accommodation cavity 111 (i.e., the left wall surface of the side frame 1101 on the right side), the front wall surface of the third plate 830 is attached to the inner front wall of the accommodation cavity 111, and the second plate 820 is located on the left side of the first plate 810. That is, the first plate 810, the third plate 830, and the second plate 820 are sequentially connected to form a second through groove 802 with the notch facing backward. The left wall surface of the first plate 810, the rear wall surface of the third plate 830, and the right wall surface of the second plate 820 form the groove walls of the second through groove 802, which helps to ensure the tight fit between the second reinforcing member 800 and the door body 100 and improve the overall stability of the door structure. At the same time, since the width of the second plate 820 is smaller than the width of the first plate 810, that is, the length of the second plate 820 in the front-rear direction is smaller than the length of the first plate 810 in the front-rear direction, it can not only reduce the weight of the door structure but also help to reduce the stress concentration points, making the stress distribution on the first plate 810 closer to the pivot side more uniform, reducing local stress concentration, and providing a stronger supporting effect on the door body 100.

[0085] In some embodiments, as Figure 2 、 Figure 3 and Figure 8 shown, the door structure further includes at least one third reinforcing member 900. The third reinforcing member 900 is disposed in the accommodation cavity 111 and is located between the first reinforcing member 700 and the second reinforcing member 800. The third reinforcing member 900 forms a third through groove 901, and the notch of the third through groove 901 is arranged facing the direction of the box body.

[0086] It can be understood that by arranging at least one third reinforcing member 900 extending in the up-down direction between the first reinforcing member 700 and the second reinforcing member 800, the stress exerted on the door body 100 during use can be more evenly distributed, and the structural strength of the door body 100 can be further enhanced. At the same time, considering that the middle part of the door body 100 is prone to arching and deforming under the action of the temperature difference between the inside and outside, the notch of the third through groove 901 faces backward, which helps to enhance the stiffness of the middle part of the door body 100 and further resist the arching deformation caused by the temperature difference.

[0087] In this embodiment, as Figure 2 and Figure 3 shown, the upper and lower ends of the third reinforcing member 900 are respectively connected to the adjacent surfaces of two decorative strips 1102, which can enhance the stability and firmness of the overall structure of the door body 100 and make it more resistant to bending and twisting.

[0088] In some embodiments, as Figure 2 and Figure 3 shown, the distance between at least one third reinforcing member 900 and the first reinforcing member 700 is less than the distance between the third reinforcing member 900 and the second reinforcing member 800.
