Description

A refrigerator

[0001] This application is based on and claims priority to Chinese patent applications CN202411844494.1 (filed December 13, 2024), CN202510045212.X (filed January 10, 2025), and CN202510005854.7 (filed January 2, 2025), the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of storage technology, such as a refrigerator. Background Technology

[0003] Side-by-side refrigerators typically have a flip-up vertical beam on one of the doors to seal the gap between the two doors and allow the door on that side to open and close independently. However, the vertical beam can easily flip over accidentally during door opening, posing a safety hazard of pinching fingers; once flipped, the beam is unstable and may interfere with the other door, preventing it from closing smoothly.

[0004] To prevent the vertical beam from accidentally tipping over, the technology incorporates an anti-tipping structure inside the beam. When a door with a vertical beam is opened, the anti-tipping structure engages with the beam's pivot point to lock it in place, preventing it from rotating. This not only avoids accidental tipping that could trap hands, but also keeps the beam in a position away from other doors, facilitating smooth closing of doors with vertical beams.

[0005] In the process of implementing the embodiments of this disclosure, it was found that at least the following problems exist in the related technology: the anti-tilting structure is set inside the vertical beam, which occupies part of the internal space of the vertical beam, resulting in the insulation material inside the vertical beam not being fully filled, making it easy for the cold air inside the refrigerator to escape from the part of the space where the anti-tilting structure is located to the front surface of the vertical beam, resulting in condensation easily forming on the front surface of the vertical beam.

[0055] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0056] As shown in Figures 1 to 35, an embodiment of this disclosure provides a refrigerator 10, which includes a cabinet 100, two doors 200, a vertical beam 300, and a condensation control assembly. The cabinet 100 forms a storage compartment 101. The two doors 200 are opposite each other and positioned on the front side of the cabinet 100 for opening and closing the storage compartment 101. The vertical beam 300 is rotatably disposed at the open end of one of the doors 200 to seal the gap between the two doors when they are closed. The condensation control assembly is disposed on at least one of the doors and is correspondingly disposed to the vertical beam.

[0057] Referring to Figures 1 to 7, specifically, both doors 200 are pivotally connected to the housing 100. One door 200 is pivotally connected to the left side wall of the housing 100, and the other door 200 is pivotally connected to the right side wall of the housing 100, thereby allowing the two doors 200, which are distributed laterally along the left and right sides of the housing 100, to open relative to each other. The vertical beam 300 is rotatably mounted at the opening end of one of the doors 200. The opening end of the door 200 is the end relative to the pivot axis between it and the housing 100, or the end closer to the other door 200. For example, the opening end of the door 200 connected to the left side wall of the housing 100 is the right end of the door 200, because its left end is pivotally connected to the housing 100, so the right end is the end relative to the pivot axis between it and the housing 100, or the end closer to the other door 200.

[0058] Two doors 200 are positioned opposite each other on the front of the cabinet 100, forming the basic structure of a double-door refrigerator to open and close the storage space. A vertical beam 300 is rotatably mounted on the open end of one of the doors 200. When both doors are closed, the vertical beam 300 precisely seals the gap between them, preventing cold air from escaping through the gap, while ensuring that the door 200 with the vertical beam 300 can be opened independently, balancing sealing performance and ease of use. The condensation control component, as the core component for condensation control, adopts a layout corresponding to the vertical beam. This can be achieved by incorporating an air guide structure and heating element in the door, or by placing a stop in the door to free up space inside the vertical beam, allowing more insulation material to be filled. This allows the surface temperature of the vertical beam to be increased through the synergistic effects of direct heating by the heating element, regulation of surface temperature and humidity by the air guide structure, and enhanced insulation by the insulation material, effectively reducing or eliminating condensation on the vertical beam.

[0059] The refrigerator provided in this embodiment of the present disclosure, through the corresponding setting of the condensation control component and the vertical beam, enables the condensation control component to act precisely on the vertical beam, effectively increasing the surface temperature of the vertical beam so that the surface temperature of the vertical beam is higher than the air dew point, thereby reducing or avoiding condensation on the vertical beam.

[0060] As shown in Figures 1 to 7, in one embodiment, the condensation control component includes an air guide structure 210. The air guide structure 210 is disposed on at least one door 200 and is located on the side of the door 200 facing the housing 100. The air guide structure 210 forms an air guide duct 211 extending longitudinally, an air inlet 212 communicating with the air guide duct 211, and a plurality of air guide holes 213 facing the other door 200. The air guide structure 210 receives external airflow through the air inlet 212 and causes the airflow to be blown by the air guide holes 213 onto the surface of the vertical beam 300 located between the two doors 200 as the airflow flows along the air guide duct 211.

[0061] The air guide structure is located on the side of the door facing the refrigerator body. The air guide structure forms an air guide duct extending longitudinally, as well as air inlet holes connected to the air guide duct and multiple air guide holes facing the other door body. The air guide structure receives external airflow through the air inlet holes and blows the airflow along the air guide duct onto the surface of the vertical beam located between the two doors, thereby accelerating the evaporation of moisture on the surface of the vertical beam and playing a decondensation role. There is no need to use heating wires for decondensation, reducing the conduction of heat into the refrigerator and thus reducing the refrigerator's energy consumption.

[0062] An air guide structure can be installed on one door or on both doors 200.

[0063] Referring to Figures 1 to 7, taking one of the door bodies 200 as an example, the air guide structure 210 is located on the side of the door body 200 facing the housing 100 and at the edge of the door body 200 near the other door body, extending from the top to the bottom of the door body 200, with a length at least greater than the length of the vertical beam. The air guide structure 210 is a hollow square column structure, and the hollow internal space is the air guide duct 211. One of the two opposing longitudinal sides of the air guide structure 210 is attached to the side of the door body 200 facing the housing 100, and the other is in contact with the surface of the vertical beam 300 when the door body 200 is closed; the other two opposing longitudinal sides face the other door body and the pivot axis between the door body 200 and the housing 100, respectively. Furthermore, an air inlet 212 is formed at the top of the air guide structure 210, and air guide holes 213 are formed on the side wall of the air guide structure 210 facing the other door body, with multiple air guide holes 213 distributed longitudinally.

[0064] Therefore, when both doors 200 are closed, the sidewalls of the two air guide structures 210 with air guide holes 213 face each other, and part of the front surface of the vertical beam 300 is located between the sidewalls of the two air guide structures 210 with air guide holes 213. The air guide structure 210 receives external airflow through the air inlet 212, and the airflow flows from top to bottom along the air guide duct 211. When it reaches the position of the air guide hole 213, the airflow flows out from the air guide hole 213 and blows towards the surface of the vertical beam 300 located between the two doors 200, that is, between the two air guide structures 210.

[0065] In this embodiment, an air guide structure 210 is provided in the door body 200. The air guide structure 210 has an air guide duct 211 inside. The air guide structure 210 can receive external airflow through the air inlet 212, allowing the airflow to flow longitudinally within the air guide duct 211. The airflow within the air guide duct 211 can flow out through the air guide hole 213 when it reaches the position of the air guide hole 213. The airflow flowing out of the air guide hole 213 can be blown towards the surface of the vertical beam 300 located between the two door bodies 200. In other words, the air guide structure 210 can deliver airflow longitudinally to different positions on the surface of the vertical beam 300 located between the two door bodies 200 through multiple air guide holes 213, thereby intensifying the airflow flow on the surface of the vertical beam 300 located between the two door bodies 200, causing the condensation on the surface of the vertical beam 300 to evaporate more quickly, thus decondensing the surface of the vertical beam 300. Because there's no need to install heating wires for decondensation within the vertical beam 300, heat generated by the heating wires is prevented from being conducted into the interior of the cabinet 100, thus reducing cold air loss inside the refrigerator and helping to reduce energy waste. Furthermore, since the heating wires are not installed within the vertical beam 300, their internal space is not occupied, allowing for more efficient filling of insulation material. This improves the insulation performance of the vertical beam 300, reducing the efficiency of cold air transfer from the interior of the cabinet 100 to the outer surface of the vertical beam 300 and decreasing the frequency of condensation on its outer surface. Additionally, since the heating wire power cord does not pass through the pivot of the vertical beam 300, the problem of frequent friction against the pivot leading to damage and electrical leakage is avoided, improving the safety of the refrigerator during use.

[0066] Furthermore, by setting air guide structures 210 on both doors 200, the dew removal efficiency of the vertical beam 300 can be improved.

[0067] It should be noted that in some other embodiments, the air guide structure may be provided only in one of the doors.

[0068] As shown in Figures 1 to 11, in one embodiment, the refrigerator 10 further includes an air intake shell 400 and a fan 500. The air intake shell 400 is disposed on the top surface of the cabinet 100. The air intake shell 400 is provided with an air inlet 410 and an air outlet 420. The air outlet 420 is connected to the air inlet 212 when the two doors 200 are closed. The fan 500 is used to generate airflow from the air inlet 410 to the air outlet 420.

[0069] Referring to Figures 1 to 11, specifically, the air intake shell 400 is provided with two air outlets 420, and the air inlet holes 212 of the two air guide structures 210 are respectively connected to the two air outlets 420 when the two doors 200 are closed. The air intake shell 400 is fixed on the top surface of the housing 100, located between the two doors 200. The fan 500 is installed inside the air intake shell 400. When the fan 500 is started, it can drive external air into the air intake shell 400 through the air inlet 410 and then out through the two air outlets 420. When the two doors 200 are closed, the two air outlets 420 are respectively connected to the two air inlet holes 212, so the airflow from the two air outlets 420 can flow to the two air guide structures 210 respectively, and then blow from the air guide holes 213 of the two air guide structures 210 to the vertical beams 300, that is, the vertical beams 300 appear from both sides of the vertical beams 300 respectively.

[0070] In this embodiment, by installing an air-guiding shell 400 and a fan 500 on the top surface of the housing 100, the air outlet 420 of the air-guiding shell 400 can connect with the air inlet 212 of the air-guiding structure 210 when the two doors 200 are closed, thereby delivering the airflow generated by the fan 500 into the air-guiding duct 211 of the air-guiding structure 210, and then blowing air onto the vertical beam 300 to achieve decondensation. Furthermore, since the air-guiding shell 400 and the fan 500 are mounted on the housing 100, they are relatively more fixed and concealed, making them less susceptible to damage.

[0071] It should be noted that in some other embodiments, the air intake casing and the fan may also be located in the box position near the bottom of the vertical beam, blowing air from the bottom of the air guide structure, or they may be installed on the door. Alternatively, the fan may be installed inside the air guide structure.

[0072] As shown in Figures 1 to 11, the air intake casing 400 also includes an air distribution structure 430, which is disposed between the fan 500 and the two air outlets 420. The air distribution structure 430 forms two air guiding surfaces, with the ends of the two air guiding surfaces close to the fan 500 connected together, and the ends away from the fan 500 connected to the two air outlets 420 respectively.

[0073] Referring to Figures 1 to 11, specifically, the air distribution structure 430 is a triangular structure, with one corner of the triangle facing the fan 500 and the other two corners connected to the two air outlets 420 respectively. Thus, the two sides of the triangle form air guide surfaces extending from the fan 500 to the two air outlets 420 respectively, which can split the airflow blown by the fan 500 into two streams that flow to the two air outlets 420 respectively.

[0074] It is understandable that by setting the air distribution structure 430 in the air intake housing 400, the airflow from the fan 500 to the two air outlets 420 can be split, so that the airflow flows more smoothly to the two air outlets 420 and the airflow to the two air guide structures 210 is more uniform.

[0075] It should be noted that in some other embodiments, the air distribution structure may also be a rounded triangle or an arc shape.

[0076] As shown in Figures 1 to 11, in one embodiment, the air outlet 420 is flush with the front side of the housing 100, and the air inlet 212 faces the housing 100 when the door 200 is closed, thus connecting with the air outlet 420. Specifically, the air outlet 420 faces the front of the housing 100, and its projection on the horizontal plane is aligned with the projection of the front side of the housing 100. The air inlet 212 faces the rear of the housing 100 when the door 200 is closed, and the outlet of the air inlet 212 is flush with the front side of the housing 100, thus enabling it to connect with the air outlet 420.

[0077] In this embodiment, by making the air outlet 420 flush with the front side of the housing 100, the air duct 400 is prevented from extending from the front end of the housing 100. This helps to prevent the air duct 400 from detaching from the housing 100 due to a collision at the position where the air duct 400 extends from the front end of the housing 100, making the installation of the air duct 400 more secure.

[0078] As shown in Figures 1 to 11, an air inlet 410 is formed on the top of the air intake housing 400, and a fan 500 is aligned with the air inlet 410 in the longitudinal direction. The rotation axis of the fan 500 extends in the longitudinal direction, and the fan 500 includes a plurality of blades 510, which extend in the longitudinal direction and are distributed around the rotation axis of the fan 500.

[0079] Referring to Figures 1 to 11, specifically, the air intake housing 400 has a generally flat structure, meaning its longitudinal dimension is small while its transverse dimension is large. An air inlet 410 is formed on the top surface of the air intake housing 400, and an air outlet 420 is formed on the side of the air intake housing 400 facing the front of the housing 100. The fan 500 includes multiple longitudinally extending blades 510 aligned with the air inlet 410, allowing the fan 500 to generate transverse airflow while maintaining a relatively small longitudinal dimension to match the small longitudinal dimension of the air intake housing 400.

[0080] In this embodiment, by forming the air inlet 410 on the top of the air intake shell 400 and providing multiple fan blades 510 on the fan 500, with the multiple fan blades 510 extending longitudinally and distributed around the rotation axis of the fan 500, the fan 500 can generate a transversely flowing airflow with a small longitudinal dimension, thereby achieving airflow supply to the air guide structure 210. Furthermore, the air intake shell 400 can also have a small longitudinal dimension, making the air intake shell 400 more concealed on the top of the cabinet 100 and avoiding affecting the overall appearance of the refrigerator 10.

[0081] As shown in Figures 4 and 5, the multiple air guide holes 213 of the air guide structure 210 are distributed longitudinally, and the air guide holes 213 of the two air guide structures 210 are staggered longitudinally. That is to say, the air guide holes 213 of the two air guide structures 210 are not aligned laterally, but are staggered. This arrangement not only allows for airflow over a larger area of ​​the vertical beam 300 with fewer air guide holes 213, but also avoids turbulence caused by mutual obstruction of the airflow from the two air guide structures 210, which would adversely affect the airflow and thus the decondensation effect.

[0082] As shown in Figures 1 to 3, in one embodiment, the wall of the air guide hole 213 is inclined along the air outlet direction and is inclined toward the vertical beam 300 when the door 200 is closed, so that the airflow from the air guide hole 213 can more easily blow toward the vertical beam 300, thereby helping to accelerate the decondensation efficiency of the vertical beam 300.

[0083] As shown in Figures 1, 4, and 12, in one embodiment, the air guide duct 211 gradually narrows from top to bottom. Specifically, the duct wall of the air guide duct 211 near the pivot axis of the door 200 is inclined, with the inclination direction from top to bottom and towards the other door. By making the air guide duct 211 gradually narrow from top to bottom, it helps to maintain a faster airflow velocity during the downward flow, thereby helping to increase the airflow velocity from the air guide hole 213, and thus improving the airflow flow at the vertical beam and the decondensation effect. At the same time, the inclined duct wall of the air guide duct 211 near the pivot axis of the door 200, with the inclination direction from top to bottom and towards the other door, can better drive the airflow towards the other door.

[0084] It should be noted that in some other embodiments, the air duct may also narrow from both sides toward the middle.

[0085] Referring to FIG6, in one embodiment, the multiple air guide holes 213 of the air guide structure 210 are distributed longitudinally, and each air guide hole 213 is provided with a damper. The damper is used to control the opening and closing of the air guide hole 213, so that the air volume blown to different positions of the vertical beam can be adjusted by adjusting the opening and closing of the air guide hole 213, thereby flexibly removing condensation according to the condensation situation at various points of the vertical beam and improving the condensation removal efficiency.

[0086] The air-guiding structure achieves efficient evaporation of condensation on the surface of the vertical beams through airflow disturbance, eliminating the need for additional heating, while also providing ample space for insulation material filling inside the vertical beams. Considering that airflow disturbance alone may result in slow decondensation speed in low-temperature and high-humidity environments, this disclosure adds a heating element inside the door to form an active temperature-raising condensation control system.

[0087] In some embodiments, the door body is equipped with both an air guide structure and a heating element, which can form a dual condensation control system of airflow evaporation and active heating. This system can retain the energy-saving advantages of the air guide structure and improve the reliability of decondensation in extreme environments through precise heat transfer.

[0088] As shown in Figures 13 and 14, in one embodiment, the condensation control component further includes a heating element 260, which is disposed on at least one door 200. The heating element 260 is disposed inside the door 200 and is located in the portion of the door 200 in the front-back direction corresponding to the vertical beam 300 when the door 200 is closed, so that the heat generated by the heating element 260 can be transferred to the vertical beam 300.

[0089] Heating elements can be installed on one door body 200 or on both door bodies 200.

[0090] Referring to Figures 1, 13, and 14, specifically, both doors 200 are pivotally connected to the housing 100. One door 200 is pivotally connected to the left side wall of the housing 100, and the other door 200 is pivotally connected to the right side wall of the housing 100, thus allowing the two doors 200, which are distributed laterally along the left and right sides of the housing 100, to open relative to each other. A vertical beam 300 is rotatably mounted at the opening end of one of the doors 200. The opening end of the door 200 is the end relative to the pivot axis between it and the housing 100, or the end closer to the other door 200. For example, the opening end of the door 200 connected to the left side wall of the housing 100 is the right end of the door 200, because its left end is pivotally connected to the housing 100, so its right end is the end relative to the pivot axis between it and the housing 100, or the end closer to the other door 200.

[0091] Optionally, continuing to refer to Figures 13 and 14, both door panels 200 are equipped with heating elements 260. The heating elements 260 are located at the edges of door panels 200 near the other door panel 200 and at the edges of door panels 200 facing the housing 100, so that the heat generated by the heating elements 260 can be transferred to the vertical beam 300 and the side wall of door panels 200 facing the other door panel. That is, the heating elements 260 are generally located at the corners of door panels 200 near the other door panel 200 and facing the housing 100, and are located inside the door panels 200. Because the vertical beam 300 contacts the corners of the two door panels 200 near the other door panel 200 and facing the housing 100 when the two door panels 200 are closed, that is, overlapping in the front-back direction, the heating elements 260 are located at the part of the door panel 200 in the front-back direction corresponding to the vertical beam 300 when the door panel 200 is closed.

[0092] As shown in Figures 1 and 13-14, the sidewalls of door 200 are made of metal, which has good thermal conductivity. When the heating element 260 starts heating, the heat from the heating element 260 can be transferred to the sidewalls of door 200 near the other door 200, that is, the sidewalls of door 200 opposite to the other door 200, and also to the sidewalls in contact with the vertical beam 300, and then to the vertical beam 300. In other words, the heating elements 260 of the two door 200s can heat the sidewalls of door 200 near the other door 200 and the vertical beam 300, thereby decondensing the condensation on the sidewalls of door 200 near the other door 200 and the vertical beam 300.

[0093] In this embodiment, a heating element 260 is installed inside the door 200 and positioned on the portion of the door 200 in the closed state corresponding to the vertical beam 300 along the front-to-back direction. This allows the heat generated by the heating element 260 to be transferred via the metal sidewall of the door 200 to the vertical beam 300 in contact with the door 200. In other words, the heating element 260 heats the vertical beam 300, thereby removing condensation from its surface. Because the heating element 260 is located inside the door 200, the power cord does not need to pass through the pivot of the vertical beam 300, thus avoiding the problem of the power cord being frequently scratched by the pivot and causing damage and leakage. This improves the safety of the refrigerator during use and simplifies the wiring process for the heating element 260's power cord. Furthermore, since the heating element 260 is not located inside the vertical beam 300, it does not occupy the internal space of the vertical beam 300. This allows the internal space of the vertical beam 300 to be filled with insulation material more fully, improving the insulation performance of the vertical beam 300. On the one hand, this helps to reduce the efficiency of cold air transfer from the inside of the cabinet 100 to the outer surface of the vertical beam 300, reducing the frequency of condensation on the outer surface of the vertical beam 300, thereby reducing the frequency of heating element activation and energy consumption. On the other hand, the heat generated by the heating element 260 is also less likely to be transferred to the inside of the cabinet 100, reducing the loss of cold air inside the refrigerator.

[0094] Furthermore, by providing heating elements 260 on both doors 200 and positioning them at the edges of the doors 200 near the other door and facing the enclosure 100, the heat generated by the heating elements 260 can be transferred to the vertical beam 300 and the side wall of the door 200 near the other door 200. In other words, the heating elements 260 can heat the side wall of the door 200 near the other door 200 and the vertical beam 300, enabling them to de-condense on the vertical beam 300 and the side of the door 200 near the other door 200. This expands the effective range of the heating elements 260 and further improves their de-condensation effect.

[0095] It should be noted that in some other embodiments, the heating element can also be a certain distance from the side wall of the vertical beam when the door is closed, and heat transfer can still be carried out, but the heating power needs to be greater.

[0096] Optionally, as shown in Figures 13 to 15, both doors 200 are provided with protrusions 220. The protrusions 220 are formed by protruding from the side of the door 200 toward the box 100 and are located at the edge of the door 200 near the other door 200. When the two doors 200 are closed, the protrusions 220 contact the vertical beam 300. The heating element 260 is disposed in the groove structure 221 formed by the protrusions 220 and the heating element 260 is attached to the inner surface of the side wall where the protrusions 220 contact the vertical beam 300.

[0097] Referring to Figures 13 to 15, specifically, in terms of the cross-sectional structure of the protrusion 220, the protrusion 220 has a side wall facing the pivot axis of the door body 200 and the housing 100, a side wall facing another door body 200, and a side wall facing the housing 100. These three side walls together form a groove structure 221 inside the door body 200, with the opening facing the front of the door body 200. The side wall facing the pivot axis of the door body 200 and the side wall facing the other door body 200 are arranged opposite to each other. The heating element 260 is disposed within the groove structure 221, and the side walls of the two protrusions 220 can fix the heating element 260. The side wall of the protrusion 220 facing the housing 100 is used to contact the vertical beam 300, and the heating element 260 adheres to the inner surface of this side wall, thereby transferring heat from the heating element 260 to the vertical beam 300.

[0098] It is understandable that by providing a protrusion 220 on the door body 200 and placing the heating element 260 within the groove structure 221 formed by the protrusion 220, on the one hand, the groove structure 221 formed by the protrusion 220 can fix the internal heating element 260, reducing additional fixing structures and simplifying the process. On the other hand, the protrusion 220 contacts the vertical beam 300, making the metal part in contact between the door body 200 and the vertical beam 300 smaller. In addition, the groove structure 221 of the protrusion 220 also forms a small heating space for the heating element 260, which is conducive to more quickly transferring the heat generated by the heating element 260 to the vertical beam 300 and the side wall of the door body 200 facing the other door body 200, reducing the excessive diffusion of heat in other useless directions, thereby improving heat utilization and decondensation efficiency.

[0099] It should be noted that in some other embodiments, only one door body may have a protrusion; that is, at least one door body may have a protrusion. Additionally, in some other embodiments, the protrusion may be positioned at a certain distance from the edge of another door body, sufficient to contact the vertical beam. Furthermore, in some other embodiments, the heating element may also be at a certain distance from the inner surface of the side wall of the vertical beam where the protrusion contacts.

[0100] As shown in Figures 14 to 16, the heating element 260 is tubular and extends longitudinally. The outer diameter of the heating element 260 is adapted to the width of the groove structure 221 formed by the protrusion 220, thereby being held by the protrusion 220. Specifically, the heating element 260 extends from the top end of the vertical beam 300 to the bottom end of the vertical beam 300 and is fixed in a vertical state by the protrusion 220.

[0101] By setting the above structure, the heating element 260 can heat and remove condensation from the vertical beam 300 more evenly. At the same time, the protrusion 220 helps to ensure that the tubular heating element 260 does not deform, thereby helping to ensure the uniformity of heating of the vertical beam 300 by the heating element 260.

[0102] As shown in Figures 14 and 15, both doors 200 also include a heat insulation pad 230. The heat insulation pad 230 is disposed on the side of the protrusion 220 facing the pivot axis of the door 200 and is fitted to the protrusion 220. The heat insulation pad 230 contacts the vertical beam 300 when both doors 200 are closed. Specifically, because the protrusion 220 is formed by protruding from the side of the door 200 facing the housing 100 and is located at the edge of the door 200 facing the other door 200, the side wall of the protrusion 220 facing the pivot axis of the door 200 and the housing 100 and the remaining part of the side wall of the door 200 facing the housing 100 will form a bent structure.

[0103] Referring again to Figures 14 and 15, the thermal insulation pad 230 is disposed at the aforementioned bending structure, thereby abutting against the side wall of the protrusion 220 facing the pivot axis of the door 200 and the housing 100, and against the side wall of the door 200 facing the housing 100. Furthermore, the thermal insulation pad 230 is made of a material with a certain degree of elasticity, and its size is larger than that of the protrusion 220 in the front-back direction of the door 200. Therefore, when both doors 200 are closed, the vertical beam 300 contacts and presses against the two thermal insulation pads 230, compressing them to the same size as the protrusion 220 in the front-back direction of the door 200, thus ensuring that the vertical beam 300 contacts both the thermal insulation pads 230 and the protrusion 220.

[0104] In this embodiment, by providing a heat insulation pad 230 on the door body 200, the heat insulation pad 230 is disposed on the side of the protrusion 220 facing the pivot axis of the door body 200 and is fitted to the protrusion 220. The heat insulation pad 230 contacts the vertical beam 300 when both doors 200 are closed. That is, the vertical beam 300 contacts both the heat insulation pad 230 and the protrusion 220 when both doors 200 are closed, thereby enabling decondensation removal from the vertical beam 300. By utilizing the contact between the insulation pad 230 and the vertical beam 300, the thermal insulation and sealing effect between the vertical beam 300 and the door 200 is improved. This reduces the conduction of cold air inside the cabinet 100 to the front surface of the vertical beam 300, thereby reducing the frequency of condensation on the vertical beam 300 and thus reducing the frequency of heating element 260 activation. It also reduces the conduction of heat from heating element 260 to the inside of the cabinet 100, avoiding loss of cold air inside the cabinet 100, and thus helping to reduce the overall energy consumption of the refrigerator.

[0105] As shown in Figures 13 to 17, the door body 200 connected to the vertical beam 300 is also provided with a first connecting part 2401. The first connecting part 2401 is formed by protruding from the side of the door body 200 toward the box body 100. The vertical beam 300 is rotatably connected to the first connecting part 2401, and the heat insulation pad 230 is disposed between the first connecting part 2401 and the protrusion 220 and is held by the first connecting part 2401 and the protrusion 220.

[0106] Referring to Figures 13 to 17, the first connecting portion 2401 is closer to the pivot axis between the door body 200 and the box body 100 than the protrusion 220. The length of the first connecting portion 2401 protruding into the box body 100 is greater than the length of the protrusion 220 protruding into the box body 100, thus allowing the vertical beam 300 to connect to the first connecting portion 2401 beyond the protrusion 220 in the direction pointing into the box body 100. Furthermore, a groove is formed between the opposite sides of the first connecting portion 2401 and the protrusion 220, and the heat insulation pad 230 is disposed in the groove between the first connecting portion 2401 and the protrusion 220. Additionally, the first connecting portion 2401 has a laterally protruding first pivot member 241, and the vertical beam 300 has a laterally extending second pivot member 330. The first pivot member 241 and the second pivot member 330 are pivotally connected, thereby allowing the vertical beam 300 to be pivotally connected to the first connecting portion 2401.

[0107] In this embodiment, by providing a first connecting part 2401 to the door body 200 connected to the vertical beam 300, the vertical beam 300 can be rotatably connected to the first connecting part 2401, and the heat insulation pad 230 is disposed between the first connecting part 2401 and the protrusion 220 and is held by the first connecting part 2401 and the protrusion 220. Thus, while realizing the connection of the vertical beam 300, the heat insulation pad 230 can be fixed, effectively preventing the heat insulation pad 230 from loosening and falling off, and improving the service life of the heat insulation pad 230.

[0108] As shown in Figure 17, the first connecting part 2401 is inclined towards the surface of the insulation pad 230, and the inclination direction is from the front side of the door 200 to the rear side and away from the insulation pad 230. That is, along the direction from the front side of the door 200 to the rear side, that is, the protruding direction of the first connecting part 2401, the surface of the first connecting part 2401 facing the insulation pad 230 moves towards the pivot axis between the door 200 and the box 100, that is, away from the insulation pad 230.

[0109] It is understandable that by tilting the first connecting part 2401 towards the surface of the insulation pad 230, with the tilt direction being from the front side of the door 200 to the rear side and away from the insulation pad 230, the insulation pad 230 has more deformation space on the side of the first connecting part 2401. When the insulation pad 230 is squeezed by the vertical beam 300, the insulation pad 230 can deform more smoothly. Compared with the insulation pad 230 being clamped by two parallel surfaces, it can avoid the formation of excessive stress inside the insulation pad 230, thereby helping to protect the insulation pad 230.

[0110] As shown in Figures 13 to 18, in one embodiment, the thickness of the contact portion between the vertical beam 300 and the insulation pad 230 is less than the thickness of the contact portion between the vertical beam 300 and the protrusion 220. As a result, in the left-right direction of the vertical beam 300, the thermal conductivity of the contact portion between the vertical beam 300 and the insulation pad 230 is worse than that of the contact portion with the protrusion 220. This facilitates the preferential conduction of heat from the protrusion 220 to the portion of the vertical beam 300 located between the two door bodies 200, thereby improving the decondensation efficiency of the vertical beam 300 and reducing energy consumption.

[0111] As shown in Figures 14 to 18, in one embodiment, the thickness of the side wall of the protrusion 220 facing the housing 100 is less than the thickness of the other two side walls. That is, the thickness of the side wall of the protrusion 220 facing the housing 100 is less than the thickness of the side wall facing the pivot axis between the door 200 and the housing 100 and the side wall facing the other door 200. This can improve the heat conduction efficiency to the vertical beam 300 and help improve the decondensation efficiency of the vertical beam 300.

[0112] As shown in Figures 14 to 19, in one embodiment, the sum of the widths of the two protrusions 220 is greater than or equal to the width of the portion of the vertical beam 300 located between the two doors 200 when they are closed. Referring to Figure 19, the width of each protrusion 220 is d, and the width of the portion of the vertical beam 300 located between the two doors 200 when they are closed is D, that is, 2d is greater than or equal to D, thereby ensuring good dew removal efficiency for the vertical beam 300.

[0113] As shown in Figures 20 and 21, in one embodiment, the heating element 260 has a tubular structure and is a flexible tube. The door 200 also includes multiple driving devices 250, which are disposed inside the door 200 and distributed longitudinally along the door 200, and are all connected to the heating element 260. The driving devices 250 are used to drive the portion of the heating element 260 connected to them to move in the front-rear direction of the door 200. Specifically, the initial position of the heating element 260 is located at the edge of the door 200 near the other door 200 and at the edge of the door 200 facing the housing 100. The driving device 250 can be a reciprocating electric drive rod. By activating the driving device 250, the heating element 260 can be pulled from the initial position toward the front of the door 200, thereby bringing the heating element 260 closer to the side wall of the door 200 facing the other door, and also moving the heating element 260 back to the initial position after it has moved away from the initial position.

[0114] In this embodiment, by providing multiple driving devices 250 distributed longitudinally along the door body 200 within the door body 200, and each driving device 250 being connected to the heating element 260, the driving devices 250 can drive the heating element 260 connected to them to move in the front-back direction of the door body 200, thereby changing the concentration point of the heat generated by the heating element 260. This allows for flexible and concentrated heating of multiple positions of the vertical beam or the side wall of the door body 200 facing another door body in the front-back direction of the door body 200, which helps to flexibly adjust the decondensation efficiency of multiple areas, thereby helping to accelerate the overall decondensation speed.

[0115] The heating element 260, through its integrated layout within the door and the grooved structure of the protruding section, enables directional heat transfer to the vertical beam. This avoids the safety hazards of traditional vertical beams with built-in heating wires and, with the assistance of insulation pads, reduces heat loss into the chamber. To fully utilize the decondensation effect of the heating element and the air-guiding structure, it is also necessary to ensure the insulation performance and posture stability of the vertical beam itself. This requires sufficient insulation of the internal space of the vertical beam to prevent continuous loss of cold air to the front surface, thereby reducing condensation. Therefore, by moving the anti-tilting stop to the door, freeing up internal space in the vertical beam to fill with insulation material, the source of cold air loss can be reduced.

[0116] As shown in Figures 1 and 22, in one embodiment, the two doors 200 are a first door 201 and a second door 700, respectively. A vertical beam 300 is rotatably disposed at the open end of the first door 201 to seal the gap between the first door 201 and the second door 700 when they are closed. The refrigerator 10 includes a cabinet 100, a first door 201, a second door 700, and a vertical beam 300. The cabinet 100 forms a storage compartment 101. The first door 201 and the second door 700 are disposed opposite each other at the front of the cabinet 100 for opening and closing the storage compartment 101. The vertical beam 300 is rotatably disposed at the open end of the first door 201 to seal the gap between the first door 201 and the second door 700 when they are closed.

[0117] Referring to Figures 1 and 22, specifically, both the first door 201 and the second door 700 are pivotally connected to the housing 100. Taking the planar orientation in Figure 22 as a reference, the first door 201 is pivotally connected to the right side wall of the housing 100, and the second door 700 is pivotally connected to the left side wall of the housing 100, thus allowing the first door 201 and the second door 700, which are distributed laterally along the left and right sides of the housing 100, to open relative to each other. The vertical beam 300 is rotatably mounted at the open end of the first door 201, which is the end of the first door 201 relative to the pivot axis with the housing 100, or the end closer to the second door 700, i.e., the left end of the first door 201. Because the right end of the first door 201 is pivotally connected to the housing 100, the left end is the end relative to the pivot axis with the housing 100, or the end closer to the second door 700.

[0118] It should be noted that this application does not limit the distribution of the first door and the second door in the box. That is, the door on the left can be the first door and the door on the right can be the second door, or the door on the right can be the first door and the door on the left can be the second door.

[0119] As shown in Figures 1 and 22 to 25, the condensation control component also includes a stop 800 and insulation material. The stop 800 is retractably disposed on the first door 201. When extended, the stop 800 abuts against the vertical beam 300, thereby preventing the vertical beam 300 from rotating relative to the first door 201. The stop 800 can retract into the first door 201 to disengage from the vertical beam 300. The insulation material is filled inside the vertical beam 300 to form an insulation structure. Specifically, when extended, the stop 800 abuts against the vertical beam 300 in a clearance position (refer to the positions of the vertical beam 300 shown in Figures 28 and 31) to prevent the vertical beam 300 from rotating. The clearance position of the vertical beam 300 is such that it can avoid the closed second door 700 when the first door 201 is in the closed position, that is, a position where the first door 201 will not hit the closed second door 700 during rotation. The insulation structure formed by filling the vertical beam 300 with insulation material can effectively block the conduction of cold air inside the refrigerator to the surface of the vertical beam, inhibiting condensation from the source, reducing cold air loss to improve the energy efficiency of the refrigerator, and is compatible with the rotation of the vertical beam and anti-tipping, achieving synergistic optimization of insulation and performance.

[0120] The anti-tipping design of the non-built-in stop 80 ensures sufficient filling of the insulation material, reducing the risk of condensation caused by cold air loss. This also complements the aforementioned air guiding structure and heating element. The air guiding structure and heating element, as active control measures, can quickly eliminate existing condensation. The stop and insulation material, as the basis for passive control, are prerequisites for reducing condensation. In some embodiments, the combined arrangement of the air guiding structure, heating element, stop, and insulation material constitutes a complete condensation control system that combines prevention and treatment. This not only solves the conflict between anti-tipping, insulation, and decondensation in traditional solutions but also achieves a balance between decondensation effectiveness, safety, and energy economy through synergistic effects.

[0121] As shown in Figures 1 and 22 to 25, specifically, the first door 201 is provided with a second connecting part 2402. The second connecting part 2402 protrudes from the side of the first door 201 facing the box 100 toward the box 100. The vertical beam 300 is pivotally connected to the surface of the second connecting part 2402 facing the second door 700 (i.e., the mounting surface 202 shown in Figure 22).

[0122] As shown in Figures 1 and 22 to 25, the stop 800 is configured to extend and retract longitudinally along the second connecting portion 2402. The vertical beam 300 is provided with a mating structure 310, which protrudes from the side of the vertical beam 300 facing the housing 100 when the first door 201 is closed. Referring to Figure 22, the side of the vertical beam 300 facing the housing 100 when the first door 201 is closed is the rear side 301 of the vertical beam shown in the figure. The mating structure 310 is used to move with the rotation of the vertical beam 300 to a position between the stop 800 and the front surface of the first door 201, thereby abutting against the stop 800 in the extended state in the front-rear direction of the first door 201. The front surface of the first door 201 is the surface facing the user when closed, or the surface facing away from the housing 100.

[0123] As shown in Figures 1 and 22 to 25, the stop member 800 is disposed on the top surface of the second connecting part 2402 and extends and retracts longitudinally. The top surface of the vertical beam 300 is higher than the top surface of the second connecting part 2402, and the mating structure 310 is disposed at a position where the vertical beam 300 is higher than the top surface of the second connecting part 2402.

[0124] Referring to Figures 1 and 22 to 25, the second connecting portion 2402 protrudes from the side of the first door 201 facing the box 100 towards the box 100, thus having a top surface, a bottom surface, and two opposing side surfaces extending towards the box 100. The top surface of the second connecting portion 2402 is lower than the top surface of the corresponding storage compartment 101, and the bottom surface of the second connecting portion 2402 is higher than the bottom surface of the corresponding storage compartment 101. A stop member 800 is longitudinally telescopically provided on the top surface of the second connecting portion 2402; that is, the stop member 800 can retract towards the first door 201 to reduce the height protruding relative to the top surface of the second connecting portion 2402. Furthermore, the second connecting portion 2402 also has a slot facing the opening inside the box 100, thereby facilitating the fixing of certain placement structures to hold stored items.

[0125] Referring again to Figures 1 and 22 to 25, the vertical beam 300 is pivotally connected to the mounting surface 202 of the second connecting part 2402. The mating structure 310 is a rod-shaped structure, which is located on the vertical beam 300 above the top surface of the second connecting part 2402, and the mating structure 310 protrudes from the rear side 301 of the vertical beam 300 toward the housing 100.

[0126] Referring to the direction of the vertical beam rotation arrows in Figures 29 to 31, when the vertical beam 300 rotates from the position where the gap between the first door 201 and the second door 700 is sealed in the closed state (refer to the state shown in Figure 22) towards the rear side of the first door 201 (i.e., the side of the first door 201 facing the box 100), that is, in the counterclockwise direction in Figures 29 to 31, the mating structure 310 will also move closer and closer to the second connecting part 2402 as the vertical beam 300 rotates, and eventually be able to move above the top surface of the second connecting part 2402 as the vertical beam 300 rotates.

[0127] Referring to Figures 1 and 22 to 25, when the stop member 800 is in the extended state, or in its original state, the height of the stop member 800 protruding from the top surface of the second connecting portion 2402 is greater than the distance between the bottom surface of the mating structure 310 and the second connecting portion 2402. In other words, the stop member 800 in the extended state can contact the mating structure 310 that has moved to its current position.

[0128] Referring to Figures 22 and 29 to 31, as the mating structure 310 approaches the second connecting portion 2402, the mating structure 310 moves from the side of the stop member 800 facing the housing 100 towards the stop member 800. When it reaches the stop member 800, the stop member 800 retracts towards the second connecting portion 2402, so that the height of its protrusion relative to the top surface of the second connecting portion 2402 is less than or equal to the distance between the bottom surface of the mating structure 310 and the second connecting portion 2402, allowing the mating structure 310 to pass over the stop member 800.

[0129] Referring to Figures 1, 22 to 25, and 28 and 31, when the mating structure 310 completely passes the stop 800 and the stop 800 returns to its extended state, the mating structure 310 is positioned between the stop 800 and the front surface of the first door body 201. In this state, the vertical beam 300 is in the avoidance position described above (refer to the position of the vertical beam 300 shown in Figures 28 and 31), and the rotation of the vertical beam 300 in the direction indicated by the vertical beam rotation arrows in Figures 29 to 31 has reached its maximum or is very close to its maximum, meaning it cannot rotate significantly in that direction. However, when the vertical beam 300 attempts to rotate in the opposite direction indicated by the vertical beam rotation arrows in Figures 29 to 31, i.e., clockwise in Figures 29 to 31, the mating structure 310 will abut against the stop 800 in its extended state, thereby hindering the rotation of the vertical beam 300.

[0130] In summary, the combination of structure 310 and stop 800 can prevent the vertical beam 300 from overturning. Then, by retracting the stop 800 towards the second connecting part 2402, the stop 800 can disengage from the vertical beam 300, allowing the first door 201 to rotate back to a position that seals the gap between the first door 201 and the second door 700 when they are closed.

[0131] In this embodiment, the vertical beam 300 is rotatably mounted at the open end of the first door 201, and a retractable stop 800 is provided on the first door 201. The stop 800, in its extended state, abuts against the vertical beam 300, thereby preventing the vertical beam 300 from rotating relative to the first door 201, effectively preventing it from tipping over. In other words, the stop 800 on the first door 201 fulfills the anti-tilting requirement of the vertical beam 300, eliminating the need for an internal anti-tilting structure. This allows for more thorough filling of insulation material inside the vertical beam 300, resulting in better insulation performance. Therefore, the vertical beam 300 better prevents cold air from escaping from the refrigerator's interior to the outside, reducing cold air waste and also helping to reduce condensation on the front surface of the vertical beam 300.

[0132] In addition, by providing a second connecting part 2402 on the first door body 201, the second connecting part 2402 protrudes from the side of the first door body 201 facing the box body 100 toward the box body 100, and the stop member 800 is provided on the second connecting part 2402, the stop member 800 avoids the part of the first door body 201 that needs to be filled with heat insulation, thus avoiding the need for additional design of the part of the first door body 201 that needs to be filled with heat insulation due to the setting of the stop member 800, thereby avoiding the irregular shape of the part of the first door body 201 that needs to be filled with heat insulation and resulting in uneven heat insulation filling.

[0133] Furthermore, by configuring the stop 800 to extend and retract longitudinally along the second connecting part 2402, and the cooperating structure 310 protruding from the side of the vertical beam 300 facing the box 100 when the first door 201 is closed, the cooperating structure 310 is used to move to a position between the stop 800 and the front surface of the first door 201 as the vertical beam 300 rotates, thereby abutting against the stop 800 in the front-rear direction of the first door 201 when it is extended. On the basis of achieving the anti-tipping requirement of the vertical beam 300, the gravity of the stop 800 is in the same direction as the extension and retraction, reducing the occurrence of the stop 800 deviating from the extension and retraction trajectory under the action of gravity, thereby making the structure of the stop 800 more stable.

[0134] Furthermore, by setting the stop 800 on the top surface of the second connecting part 2402 and setting the mating structure 310 at a position where the vertical beam 300 is higher than the top surface of the second connecting part 2402, the anti-overturning requirement of the vertical beam 300 is met, and the setting positions of the mating structure 310 and the stop 800 are easy to observe. This makes it easier to set a structure for installing the stop 800 on the second connecting part 2402, thereby facilitating production and installation.

[0135] It should be noted that in some other embodiments, the stop member can also be provided on the side of the second connecting part 2402 facing the second door body. It can be that a receiving groove is provided on the side of the second connecting part 2402 facing the second door body to allow the second connecting part 2402 to extend and retract, so as to install the longitudinally extending stop member; or it can be that the telescopic member extends and retracts along the left and right direction of the first door body.

[0136] It should be noted that in some other embodiments, the first door body may not have the second connecting part 2402, that is, the vertical beam is connected to the surface of the first door body facing the box body, and the stop member is also provided on the surface of the first door body facing the box body.

[0137] As shown in Figures 1 and 22 to 25, in one embodiment, the refrigerator 10 further includes an elastic member 600 disposed between the stop member 800 and the second connecting portion 2402. The elastic member 600 is used to support the stop member 800 in an extended state and to allow the stop member 800 to retract toward the first door 201 via the compression elastic member 600.

[0138] Referring to Figures 1 and 22 to 25, specifically, the elastic element 600 is a spring capable of longitudinal extension and contraction. The elastic element 600 is disposed at the bottom of the stop 800. When the assembly consisting of the stop 800 and the elastic element 600 is not subjected to external force, the elastic element 600 supports the stop 800 in its extended state. When the stop 800 is subjected to a large external force, it can compress the elastic element 600, thereby retracting towards the second connecting portion 2402. When the external force is removed, the stop 800 can return to its extended state under the elastic force of the elastic element 600.

[0139] As shown in Figures 1 and 22 to 25, the second connecting part 2402 is provided with a mounting groove 242. The mounting groove 242 is provided on the top surface of the second connecting part 2402 and extends longitudinally. The stop member 800 and the elastic member 600 are provided in the mounting groove 242, and the elastic member 600 is provided at the bottom of the stop member 800. The shape of the mounting groove 242 is adapted to the shape of the stop member 800 so as to guide the movement direction of the stop member 800.

[0140] Referring to Figures 1 and 22 to 25, specifically, the mounting groove 242 is formed by hollowing out the top surface of the second connecting portion 2402. The space of the mounting groove 242 is generally cuboid. The portion of the stop member 800 located within the mounting groove 242 is cuboid in shape to fit the internal space of the mounting groove 242, thereby allowing the stop member 800 to move longitudinally within the mounting groove 242. Furthermore, the four side walls of the mounting groove 242 can abut against the four side walls of the stop member 800, preventing the stop member 800 from shifting laterally, that is, guiding the stop member 800 to move in a precise longitudinal direction. The elastic member 600 is disposed between the bottom surface of the stop member 800 and the bottom surface of the mounting groove 242.

[0141] Those skilled in the art will understand that by providing an elastic member 600 between the stop member 800 and the second connecting portion 2402, the elastic member 600 can support the stop member 800 in the extended state. That is, while keeping the stop member 800 in a state that can abut against the vertical beam 300 to prevent the vertical beam 300 from rotating, the elastic member 600 can compress the stop member 800 under the action of a large external force, thereby contracting towards the second connecting portion 2402 and disengaging from the abutment with the vertical beam 300. When the external force is removed, the stop member 800 can return to the extended state under the elastic force of the elastic member 600. Thus, the stop member 800 can automatically disengage from the abutment with the vertical beam 300 and automatically return to the extended state. On the basis of realizing the anti-overturning function of the vertical beam 300, the drive mechanism and control system for controlling the movement of the stop member are reduced or eliminated, making the anti-overturning structure simpler.

[0142] In addition, by providing a mounting groove 242 in the second connection part 2402, the stop member 800 and the elastic member 600 are disposed in the mounting groove 242. The shape of the mounting groove 242 is adapted to the shape of the stop member 800, so that the mounting groove 242 can guide the movement direction of the stop member 800, thereby helping to reduce the occurrence of the stop member 800 deviating in a direction other than the extension direction during the extension and retraction process, making the movement of the stop member 800 smoother.

[0143] It should be noted that in some other embodiments, instead of using a mounting groove, a protruding post is provided on the second connecting part 2402, and the stop member is provided with a matching groove of the corresponding shape of the protruding post to guide the extension and retraction of the stop member.

[0144] It should be noted that in some other embodiments, the elastic element may not be provided. Instead, the retraction of the stop element may be controlled by an electric drive structure, or the user may manually adjust the state of the stop element. That is, after opening the door, the user may manually rotate the vertical beam to the locking position and manually stretch the stop element to the extended state to lock the vertical beam. When closing the door, the user may manually retract the stop element toward the first door body to unlock the vertical beam.

[0145] As shown in Figure 25, in one embodiment, the stop member 800 is provided with a guide surface 810, which is located on the side of the stop member 800 facing the housing 100, so as to facilitate the mating structure 310 pressing the stop member 800. The guide surface 810 is an inclined surface that slopes downward from top to bottom and toward the direction of the housing 100.

[0146] Referring to the direction of the vertical beam rotation arrows in Figures 29 to 31, as the mating structure 310 approaches the second connecting portion 2402, the mating structure 310 moves from the side of the stop member 800 facing the housing 100 towards the stop member 800. When it reaches the stop member 800, it first contacts the guide surface 810 of the stop member 800, thereby applying external force to the stop member 800. This causes the stop member 800 to compress the elastic member 600, resulting in the height of the stop member 800 protruding relative to the top surface of the second connecting portion 2402 continuously decreasing as the mating structure 310 compresses it, until the mating structure 310 passes over the stop member 800. Then, the stop member 800 returns to its extended state under the action of the elastic member 600.

[0147] Those skilled in the art will understand that by providing a guide surface 810 on the stop 800, the mating structure 310 can contact and press the stop 800 via the guide surface 810 during the movement of the mating structure 310 towards the position between the stop 800 and the front surface of the first door body 201, making it easier for the mating structure 310 to compress the stop 800.

[0148] As shown in Figures 1 and 22 to 24, the vertical beam 300 is provided with guide ribs 320, which protrude upwards from the top surface of the vertical beam 300. The box body 100 is provided with a guide groove 102, which is located on the bottom surface of the top wall of the box body 100 and forms an opening 103 on the front surface of the top wall of the box body 100. This allows the guide ribs 320 to enter and exit the guide groove 102 through the opening 103, thereby limiting the movement path of the guide ribs 320 during the opening and closing of the first door 201, and consequently limiting the rotation path of the vertical beam 300 relative to the first door 201.

[0149] Referring to Figure 22, with the vertical beam 300 sealing the gap between the first door body 201 and the second door body 700 as a reference, the guide rib 320 protrudes upward from the top surface of the vertical beam 300 and has an arc-shaped structure extending approximately in the left-right direction of the box body 100. That is, the surface of the guide rib 320 facing the rear side of the first door body 201 is a convex arc-shaped surface facing the rear side of the first door body 201, and the surface facing the front side of the first door body 201 is a concave arc-shaped surface facing the front side of the first door body 201. The guide groove 102 is formed by hollowing out the bottom surface of the top wall of the box body 100 above the box body 100 and penetrating the front surface of the top wall of the box body 100, thereby forming an opening 103 on the front surface of the top wall of the box body 100 that connects to the guide groove 102. The width of the opening 103 in the left-right direction is matched with the thickness of the guide rib 320 (the dimension along the front-back direction of the first door 201 when the vertical beam 300 seals the gap between the first door 201 and the second door 700).

[0150] Referring to Figures 22 to 24, the guide groove 102 has a groove wall extending in the front-rear direction of the housing 100 and a groove wall extending in the left-right direction of the housing 100. The front end of the groove wall extending in the front-rear direction of the housing 100 is connected to the opening 103, and the groove wall extending in the left-right direction of the housing 100 is connected to the rear end of the groove wall extending in the front-rear direction of the housing 100. When the vertical beam 300 is in the state of sealing the gap between the first door body 201 and the second door body 700, the entire guide rib 320 is located in the guide groove 102.

[0151] Referring to Figures 1 and 22 to 25, and the rotation arrows indicating the first door 201 in Figures 26 to 28, when the first door 201 is opened, the guide rib 320 gradually approaches the wall of the guide groove 102 extending along the front-rear direction of the housing 100. Upon contact with the wall of the guide groove 102 extending along the front-rear direction of the housing 100, the guide rib 320, guided by the wall of the guide groove 102, changes its arc shape to a state along the front-rear direction of the first door 201, thereby causing the vertical beam 300 to rotate towards the rear of the first door 201 (that is, the direction indicated by the rotation arrows of the vertical beam in Figures 29 to 31). Ultimately, the arc shape of the guide rib 320 extends along the front-rear direction of the first door 201, meaning that the two arc surfaces of the guide rib 320 face the pivot end and the open end of the first door 201, respectively. In other words, the vertical beam 300 is in the avoidance position described above, which is the state shown in Figures 28 and 31. At this point, the guide rib 320 can exit the guide groove 102 from the opening 103. Furthermore, the stop member 800 locks the vertical beam 300 in this state.

[0152] When the first door 201 needs to be closed, because the vertical beam 300 is locked in the avoidance position, that is, just leaving the guide groove 102 from the opening 103, when the vertical beam 300 returns to the opening 103 of the guide groove 102 as the first door 201 closes, the guide rib 320 can then enter the guide groove 102 from the opening 103. After entering the guide groove 102, the guide rib 320 first contacts the groove wall of the guide groove 102 extending in the front-rear direction of the box body 100. As the first door 201 continues to close, the guide rib 320 gradually approaches the groove wall of the guide groove 102 extending in the left-right direction along the box 100. Upon contact with the groove wall of the guide groove 102 extending in the left-right direction along the box 100, the arc shape of the guide rib 320, guided by the groove wall of the guide groove 102, changes to a state along the left-right direction of the first door 201, thereby causing the vertical beam 300 to rotate towards the front of the first door 201 (that is, in the opposite direction of the vertical beam rotation arrows in Figures 29 to 31). Finally, the first door 201 is completely closed, and the arc shape of the guide rib 320 extends in the left-right direction along the first door 201, that is, the two arc surfaces of the guide rib 320 face the front and rear sides of the first door 201 respectively, returning to the position of the first door 201 and the second door 700 in a sealed closed state, with the vertical beam 300 in the state shown in Figures 26 and 29.

[0153] As shown in Figures 23, 32, and 33, the mating structure 310 and the extended stop 800 abut against each other in a longitudinal plane, thereby preventing the vertical beam 300 from rotating. The housing 100 is provided with a pressing protrusion 110, which is located on the bottom surface of the top wall of the housing 100 and protrudes downward from the housing 100. The pressing protrusion 110 is used to press the stop 800 during the closing of the first door 201, causing the stop 800 to retract towards the first door 201.

[0154] Referring to Figures 1 and 22 to 33, specifically, the cooperation between the guide rib 320 and the guide groove 102 forces the vertical beam 300 to rotate during the opening and closing of the first door 201. When the cooperating structure 310 abuts against the stop 800 to lock the vertical beam 300, the two abut against each other in a longitudinal plane. The cooperating structure 310 applies force to the stop 800 along the abutment direction, but cannot cause the stop 800 to retract towards the second connecting portion 2402. Therefore, during the closing process of the first door 201, the vertical beam 300 cannot rotate unless force in other directions is applied to the stop 800.

[0155] Therefore, the pressing protrusion 110 on the housing 100 presses the stop member 800 from the top, and the contact position between the pressing protrusion 110 and the stop member 800 avoids the mating structure 310, so that the stop member 800 is disengaged from the mating structure 310 in the longitudinal plane. At the same time, as shown in FIG34, in the closing direction of the first door 201 (in the direction indicated by the horizontal arrow in FIG34), the mating structure 310 and the pressing protrusion 110 are offset, so that the mating structure 310 can pass over the stop member 800 and reach the side of the stop member 800 facing the rear of the first door 201 after the pressing protrusion 110 presses the stop member 800.

[0156] As shown in Figures 1, 22 to 25, and 31, the mating structure 310 also has two guide surfaces 311, which are respectively located on opposite sides of the mating structure 310 along the rotation path of the vertical beam 300. That is, when the mating structure 310 contacts the stop 800 from the side facing the rear of the first door body 201, it can contact the stop 800 using one guide surface 311. Conversely, when the mating structure 310 contacts the stop 800 from the side facing the front of the first door body 201, it can contact the stop 800 using the other guide surface 311. This makes it easier for the mating structure 310 to press against the stop 800.

[0157] Referring to Figures 1 and 22 to 34, during the opening of the first door 201 (refer to the rotation arrows of the first door 201 in Figures 26 to 28), as the first door 201 opens, the vertical beam 300 is forcibly rotated under the cooperation of the guide rib 320 and the guide groove 102. The rotation direction is indicated by the rotation arrows of the vertical beam in Figures 29 to 31. As the vertical beam 300 rotates, the mating structure 310 also moves closer and closer to the stop member 800 from the side facing the rear of the first door 201, and eventually moves to a position in contact with the stop member 800 as the vertical beam 300 rotates. Then, a guide surface 311 of the mating structure 310 contacts the guide surface 810 of the stop member 800, compressing the stop member 800, causing the stop member 800 to compress the elastic member 600 and contract towards the second connecting portion 2402. Finally, the mating structure 310 can pass over the stop 800, and the stop 800 returns to its extended state. At this time, the mating structure 310 is located on the side of the stop 800 facing the front of the first door body 201. The mating structure 310 will abut against the stop 800 in its extended state with a longitudinal plane, thereby hindering the rotation of the vertical beam 300.

[0158] During the closing process of the first door 201 (refer to the opposite direction of the rotation arrows of the first door in Figures 26 to 28), as the first door 201 closes, the guide ribs 320 of the vertical beam 300 enter the guide groove 102 and are forced to rotate under the cooperation of the guide ribs 320 and the guide groove 102, in the opposite direction of the rotation arrows of the vertical beam in Figures 29 to 31. At this time, the second connecting part 2402 also comes to the bottom of the top wall of the box 100. As the first door 201 continues to close, the pressing protrusions 110 on the top wall of the box 100 contact and squeeze the stop member 800, causing the stop member 800 to retract towards the second connecting part 2402. When the stop member 800 is squeezed to the top and contacts the guide surface 311 of the mating structure 310, the mating structure 310 can pass over the stop member 800 under the guidance of the guide surface 311 and return to the side of the stop member 800 facing the rear of the first door 201. Then, the stop 800 returns to its extended state. At this time, the vertical beam 300 can rotate freely, the first door 201 closes in place, and the vertical beam 300 moves to the position that seals the gap between the first door 201 and the second door 700.

[0159] In this embodiment, by setting guide ribs 320 on the vertical beam 300 and guide grooves 102 on the cabinet 100, the vertical beam 300 can be forced to rotate through the cooperation between the guide ribs 320 and the guide grooves 102 during the opening and closing of the first door 201. This provides external force to the cooperating structure 310 to press the stop member 800, so that the vertical beam 300 can automatically press the stop member 800 as the first door 201 opens and closes, thus locking or unlocking the vertical beam 300 without additional operation, making the use of the refrigerator 10 more convenient.

[0160] It should be noted that in some other embodiments, guide ribs and guide grooves may not be provided, and the user may manually apply external force to rotate the vertical beam to achieve locking or unlocking.

[0161] Furthermore, by having the mating structure 310 and the extended stop 800 abut against each other in a longitudinal plane, the anti-tipping state of the vertical beam 300 can be made more stable. Further, by providing a pressing protrusion 110 in the housing 100, the pressing protrusion 110 can press against the stop 800 during the closing of the first door 201, causing the stop 800 to retract towards the first door 201. Thus, while the mating structure 310 and the extended stop 800 abut against each other in a longitudinal plane to prevent the vertical beam from tipping over, the vertical beam 300 can also be automatically unlocked as the first door 201 closes, making operation more convenient.

[0162] It should be noted that in some other embodiments, when the vertical beam is prevented from tipping over by the longitudinal plane abutting between the cooperating structure and the stop in the extended state, the pressing protrusion may not be provided. Instead, the user can manually unlock the vertical beam when the first door needs to be closed.

[0163] Additionally, referring to FIG35, in some other embodiments, when guide ribs and guide grooves are provided, a groove can be provided in one of the stop member 800 and the mating structure 310, so that the other of the stop member 800 and the mating structure 310 has a protrusion that matches the shape of the groove. The protrusion is embedded in the groove to prevent the vertical beam from tipping over. Furthermore, the groove is inclined from the middle to both sides along the abutment direction of the stop member 800 and the mating structure 310. In this way, after the stop member 800 and the mating structure 310 lock the vertical beam, the stop member 800 and the mating structure 310 will not disengage unless the vertical beam is subjected to a particularly large external force. Only when the vertical beam is subjected to a large external force will the stop member 800 and the mating structure 310 disengage due to the existence of the inclined surface of the groove. Therefore, there is no need to provide a pressing protrusion.

[0164] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
