Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to a refrigerator. Background Art

[0002] Refrigerators are widely used in homes for their ability to preserve and freeze food, and are a favorite among consumers. Refrigerators consist of a cabinet and a door, using an internal refrigeration compartment to refrigerate or freeze food. The door closes and opens the compartment. The door needs to be opened to remove or place food. However, when the door is open, convection currents between the cold and hot air inside the refrigeration compartment cause a large amount of cold air to escape, resulting in cooling leakage and increased energy consumption.

[0003] There is an air-cooled refrigerator in the related technology, which is characterized in that it includes: a refrigerator body, having two openings arranged opposite to each other; two door bodies, namely a first door body and a second door body, the first door body is used to close or open the first opening on the refrigerator body, and the second door body is used to close or open the second opening on the refrigerator body; and at least one air curtain assembly, which is arranged inside the refrigerator body and can generate an air curtain to reduce the loss of cold air in the refrigerator body.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] The method of reducing the loss of cold air inside the refrigerator by forming an air curtain by setting an air curtain assembly is costly, and the airflow blown out by the air curtain assembly will lead to a poor user experience. When taking and placing food, the airflow direction of the air curtain will change due to the obstruction of the user's hands and the food, which will still cause the cold air inside the refrigerator to overflow with the airflow of the air curtain.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0040] Combine Figure 1-3 As shown, in some embodiments, a refrigerator includes: a cabinet 100, a door 200, and a folding structure 300. A refrigeration compartment 110 is provided inside the cabinet 100; one side of the door 200 is rotatably connected to a side of the cabinet 100 for closing or opening the refrigeration compartment 110; the folding structure 300 is disposed between the cabinet 100 and the door 200, with one side of the folding structure 300 connected to the cabinet 100 and the other side connected to the door 200; wherein, when the door 200 is open, the folding structure 300 unfolds with the door 200 to prevent the cold air flowing out of the opening of the refrigeration compartment 110 from sinking; when the door 200 is closed, the folding structure 300 folds with the door 200.

[0041] The refrigerator provided by the embodiment of the present disclosure has a foldable folding structure 300 provided between the cabinet 100 and the door 200. When the door 200 is opened to take food in or out, the folding structure 300 unfolds with the door 200 to block the bottom of the opening of the refrigeration compartment 110. This can receive and block the downward flow of cold air overflowing from the refrigeration compartment 110, reducing the occurrence of cold and hot convection, thereby reducing the overflow of cold from the refrigeration compartment 110 and lowering the energy consumption of the refrigerator. When the door 200 is closed, the folding structure 300 folds and hides along with the door 200. By providing the folding structure 300 to receive and block the downward flow of cold air, the purpose of reducing the leakage of cold from the refrigeration compartment 110 is achieved, reducing the cost of the refrigerator and improving the user experience.

[0042] Optionally, the housing 100 is a rectangular body, and the door 200 is a rectangular plate. The long sides of the door 200 are pivotally connected to the long sides of the front sidewall of the housing 100. The front sidewall of the housing 100 is a rectangular wall, and the long sides of the front sidewall of the housing 100 are perpendicular to the horizontal plane. This makes the overall shape of the refrigerator more regular, easier to place, and more stable. By pivotally connecting the long sides of the door 200 to the long sides of the front sidewall of the housing 100, the door 200 occupies relatively less space when it is rotated open, improving the user experience.

[0043] Optionally, the folding structure 300 is arranged horizontally, and when the folding structure 300 is unfolded along with the door body 200, the plane formed by the folding structure 300 is parallel to the horizontal plane. In this way, when the folding structure 300 is unfolded along with the door body 200, a planar blocking area is formed below the opening of the refrigeration compartment 110, which can better prevent the cold air flowing out of the refrigeration compartment 110 from sinking, thereby reducing the leakage of cold air in the refrigeration compartment 110.

[0044] For example, the opening angle of the door body 200 is greater than 0° and less than or equal to 90°. When the opening angle of the door body 200 is 0°, the door body 200 is in a closed state. When the opening angle of the door body 200 is 90°, the door body 200 is opened to the maximum angle. When the door body 200 is rotated and opened to any angle, the folding structure 300 is pulled by the door body 200 and unfolds to the maximum extent when the door body 200 is opened to 90°. At this time, the upper side wall of the folding structure 300 forms a planar structure.

[0045] Optionally, the folding structure 300 is a fan-shaped structure, with the lengths of both sides of the folding structure 300 being the same as the width of the opening of the refrigeration compartment 110. Thus, since the width of the door 200 matches the width of the front sidewall of the cabinet 100, and the width of the opening of the refrigeration compartment 110 is smaller than the widths of the cabinet 100 and the door 200, setting the lengths of both sides of the folding structure 300 to be the same as the width of the opening of the refrigeration compartment 110 allows the folding structure 300 to be properly installed between the door 200 and the cabinet 100. Furthermore, the folding structure 300 has a more regular shape, and the fan-shaped blocking surface formed therein better blocks the sinking of cold airflow. When the door 200 is opened, the folding structure 300 can unfold to form a relatively large blocking area to block and receive cold airflow overflowing from the refrigeration compartment 110. The folding structure 300 is set to a fan-shaped structure. When the folding structure 300 is opened, the curved edge of the folding structure 300 can extend along the opening trajectory of the door body 200. The folding structure 300 will not protrude from the door body 200 and the box body 100, reducing the risk of interference with users who take and place items when the folding structure 300 is opened.

[0046] Specifically, one side of the folding structure 300 is connected to the rear side wall of the door body 200 . The rear side wall of the door body 200 refers to the side wall of the door body 200 facing the inside of the refrigeration compartment 110 when the door body 200 is in the closed state.

[0047] It can be understood that the two side edges of the folding structure 300 refer to the two radial edges of the fan-shaped structure.

[0048] Optionally, the location where the folding structure 300 is connected to the cabinet 100 is located below the opening of the refrigeration compartment 110. In this way, the blocking surface formed by the folding structure 300 when unfolded is located below the opening of the refrigeration compartment 110, thereby better blocking the sinking of the cold airflow overflowing from the entire refrigeration compartment 110, and increasing the amount of cold airflow received, thereby further reducing the amount of cold air leaking out of the refrigeration compartment 110.

[0049] Specifically, the position where the folding structure 300 is connected to the box body 100 is located below the lower edge of the opening of the refrigeration compartment 110 .

[0050] Optionally, a set distance is provided vertically between the lower edge of the opening of the refrigerating compartment 110 and the side where the folding structure 300 is connected to the box body 100. This provides a certain clearance distance between the side where the folding structure 300 is connected to the box body 100 and the lower edge of the opening of the refrigerating compartment 110. This allows the unfolded folding structure 300 to effectively block cold airflow from the opening of the refrigerating compartment 110 and reduces the risk of interference between the folding structure 300 and food when placing or removing food.

[0051] Optionally, set the distance to 2 cm.

[0052] Combine Figure 4 and Figure 5 As shown, in some embodiments, a receiving groove 120 is provided at the location where the side wall of the cabinet 100 is connected to the folding structure 300, and one side of the folding structure 300 is connected to the inner wall of the receiving groove 120. When the folding structure 300 is folded along with the door body 200, the folding structure 300 is retracted into the receiving groove 120. In this way, by providing the receiving groove 120 on the side wall of the cabinet 100 and utilizing the receiving groove 120 to accommodate the folding structure 300, when the door body 200 is closed and the folding structure 300 is folded along with the door body 200, the folding structure 300 can be retracted into the receiving groove 120 for concealment, thereby reducing the impact of the folding structure 300 on the sealing performance of the door body 200. This improves the sealing performance of the refrigeration compartment 110 while reducing the leakage of cold air from the refrigeration compartment 110 when the door body 200 is opened. Moreover, since the thickness of the box body 100 is relatively large and the thickness of the door body 200 is relatively small, a receiving groove 120 is opened at a corresponding position of the side wall of the box body 100 to reduce the influence of the opening of the receiving groove 120 on the heat preservation effect of the refrigerator.

[0053] It can be understood that both sides of the folding structure 300 are connected to the door body 200 and the side walls of the accommodating groove 120 by means of screws, snaps or bonding, which will not be described in detail here.

[0054] Combine Figure 4 As shown, in one embodiment, the rear inner wall of the receiving groove 120 is parallel to the front wall of the box body 100, and the depth of the receiving groove 120 is greater than the maximum thickness of the folding structure 300 after folding. In this way, the receiving groove 120 is formed into a rectangular groove structure, allowing the folded folding structure 300 to be more smoothly retracted into the receiving groove 120 for concealment. Since the thickness of the folded folding structure 300 varies, the depth of the receiving groove 120 is set to be greater than the maximum thickness of the folding structure 300 after folding, so that the folding structure 300 can be more easily retracted into the receiving groove 120 for concealment.

[0055] It can be understood that the depth of the accommodating groove 120 refers to the depth of the accommodating groove 120 in a direction perpendicular to the plane where the opening of the refrigerating compartment 110 is located.

[0056] Combine Figure 5 As shown, in another embodiment, the rear inner wall of the receiving groove 120 is inclined relative to the front side wall of the box body 100, and the depth of the receiving groove 120 gradually decreases along its length. In this way, since the thickness of the folding structure 300 after folding varies, the thickness of the folding structure 300 gradually decreases along its length. Therefore, the receiving groove 120 with an inclined rear side wall is provided in the side wall of the box body 100. The depth of the receiving groove 120 is adapted to the thickness of the folding structure 300, which reduces the space required for the receiving groove 120, thereby reducing the impact of the receiving groove 120 on the thermal insulation performance of the box body 100.

[0057] Specifically, the thickness of the folding structure 300 gradually decreases along its length from its head to its tail after folding; and the depth of the accommodating groove 120 gradually decreases along the horizontal direction from the non-connected vertical side of the door body 200 to the connected vertical side of the door body 200. Thus, because the folding structure 300 is a fan-shaped structure, the thickness of the folding structure 300 gradually decreases along its length from its head to its tail after folding. The gradually decreasing depth of the accommodating groove 120 along the horizontal direction from the non-connected vertical side of the door body 200 to the connected vertical side of the door body 200 allows the accommodating groove 120 to better accommodate the placement of the folding structure 300.

[0058] Optionally, the angle of inclination between the rear inner wall of the receiving groove 120 and the front wall of the box body 100 is the same as the angle of inclination between the two side edges of the folded folding structure 300. In this way, the depth of the receiving groove 120 is fully adapted to the depth of the folded folding structure 300, while accommodating the folded folding structure 300 and further reducing the space occupied by the receiving groove 120 in the box body 100.

[0059] Combine Figure 6As shown, in some embodiments, the folding structure 300 includes an upper folding sheet 310 and a lower folding sheet 320. The upper folding sheet 310 is connected to the cabinet 100 on one side and to the door 200 on the other side. The lower folding sheet 320 is disposed below the upper folding sheet 310, with one side of the lower folding sheet 320 connected to the cabinet 100 and the other side connected to the door 200. An airflow cavity 340 is formed between the upper folding sheet 310 and the lower folding sheet 320. A through hole 330 is provided on the side wall of the upper folding sheet 310, so that cold air flowing out of the opening of the refrigeration compartment 110 can flow into the airflow cavity 340 through the through hole 330. In this way, the folding structure 300 is divided into an upper folding piece 310 and a lower folding piece 320. The two side edges of the upper folding piece 310 and the lower folding piece 320 are also connected to the door body 200 and the box body 100 respectively. The upper folding piece 310 and the lower folding piece 320 jointly define an airflow cavity 340. When the folding structure 300 is unfolded, the cold air overflowing from the opening of the refrigeration compartment 110 can sink into the airflow cavity 340 along the through holes 330 on the side walls of the upper folding piece 310. While the folding structure 300 blocks the overflowing cold air flow from sinking, the airflow cavity 340 collects the cold air overflowing from the refrigeration compartment 110. When the door body 200 is closed, the folding structure 300 folds along with the closing of the door body 200, and the airflow cavity 340 is squeezed to become smaller during folding, thereby squeezing and ejecting the collected cold air flow from the through hole 330. The cold air flow ejected from the through hole 330 is ejected to the front of the opening of the refrigeration compartment 110. As the door body 200 is closed, the cold air flow in this area is driven to flow back into the refrigeration compartment 110, compensating for the cold air flow overflowing from the refrigeration compartment 110, thereby further reducing the leakage of the cold air flow in the refrigeration compartment 110 and reducing the energy consumption of the refrigerator.

[0060] Optionally, the upper folding piece 310 and the lower folding piece 320 are both identical fan-shaped folding pieces. When the folding structure 300 is unfolded as the door body 200 is opened, the upper folding piece 310 and the lower folding piece 320 are unfolded synchronously. When the folding structure 300 is folded as the door body 200 is closed, the upper folding piece 310 and the lower folding piece 320 are folded synchronously.

[0061] For example, the fan-shaped folding sheet has the same structure as the fan surface of a folding fan, and can be unfolded to form a plane, and can also be folded to form a plate-like structure.

[0062] Optionally, each folding surface of the upper folding piece 310 and the lower folding piece 320 is provided with a reinforcing rib. This can enhance the strength of the upper folding piece 310 and the lower folding piece 320, and can also guide the folding of the upper folding piece 310 and the lower folding piece 320, thereby reducing the risk of the upper folding piece 310 and the lower folding piece 320 being offset during folding.

[0063] Optionally, when the door body 200 is opened to the maximum door opening angle, the upper folding piece 310 and the lower folding piece 320 are both unfolded to form a planar structure.

[0064] Optionally, when both the upper folding piece 310 and the lower folding piece 320 are unfolded to form a planar structure, the vertical distance between the upper folding piece 310 and the lower folding piece 320 is greater than twice the height of the upper folding piece 310 after folding. In this way, the upper folding piece 310 and the lower folding piece 320 will not interfere with each other after folding, thereby making the folding structure 300 fold more neatly, facilitating the concealment of the folded folding structure 300, and preventing deformation of the folding structure 300 from affecting the sealing of the door body 200.

[0065] It can be understood that the side edge on which the folding structure 300 is connected to the door body 200 refers to the side edge formed by one side edge of the upper folding piece 310 and one side edge of the lower folding piece 320, and the other side edge on which the folding structure 300 is connected to the box body 100 refers to the side edge formed by the other side edge of the upper folding piece 310 and the other side edge of the lower folding piece 320.

[0066] Specifically, one side of the upper folding piece 310 and the lower folding piece 320 are connected to the rear side wall of the door body 200, and the other side of the upper folding piece 310 and the lower folding piece 320 are connected to the rear side wall of the accommodating groove 120 opened on the side wall of the box body 100.

[0067] Specifically, the set distance between the folding structure 300 and the lower edge of the opening of the refrigerating compartment 110 refers to the distance between the side where the upper folding piece 310 is connected to the box body 100 and the lower edge of the opening of the refrigerating compartment 110 .

[0068] Optionally, multiple through-holes 330 are provided, and the multiple through-holes 330 are evenly distributed on the upper sidewall of the upper foldable sheet 310. Thus, by providing multiple through-holes 330 extending through the upper sidewall of the upper foldable sheet 310, a large amount of the cold airflow blocked and received by the upper sidewall of the upper foldable sheet 310 can be allowed to sink into the airflow cavity 340, thereby increasing the amount of cold air collected. Evenly distributing the multiple through-holes 330 makes the cold airflow collected in the airflow cavity 340 more uniform. Furthermore, when the door 200 is closed, the cold airflow ejected from the airflow cavity 340 is more evenly distributed in front of the opening of the refrigeration compartment 110. As the door 200 closes, the ejected cold airflow is more evenly returned to the refrigeration compartment 110.

[0069] Combine Figure 7 and Figure 8As shown, in some embodiments, a guide tube 400 is provided inside the cabinet 100. The input end of the guide tube 400 extends to the folding structure 300 and communicates with the airflow cavity 340, and the output end of the guide tube 400 extends to the heating device 500 of the refrigerator. In this way, by providing the guide tube 400 in communication with the airflow cavity 340, when the door 200 is closed, the folding structure 300 folds along with the door 200. During the folding process, the cold air in the airflow cavity 340 is squeezed, causing part of the cold air in the airflow cavity 340 to flow from the guide tube 400 to the heating device 500 of the refrigerator. The guide tube 400 then guides the cold air collected in the airflow cavity 340 to the heating device 500 for cooling, and the collected cold air is reused, thereby improving the user experience.

[0070] Optionally, the flow conduit 400 is embedded in the foam layer of the refrigerator, with the input end of the flow conduit 400 extending to the rear wall of the accommodating tank 120 and communicating with the airflow cavity 340. In this way, the foam layer of the refrigerator can be used to insulate the flow conduit 400, reducing heat exchange as the cold air flows through the flow conduit 400 toward the heating element 500, thereby ensuring a cooling effect on the heating element 500.

[0071] Optionally, the guide tube 400 is vertically arranged, and the input end of the guide tube 400 is located above the output end of the guide tube 400. In this way, due to the natural downward sinking characteristics of the cold air flow, the cold air flow can naturally flow toward the heating device 500 along the vertical guide tube 400 without power.

[0072] Optionally, the heating element 500 includes one or more of a condenser, a side panel, and a compressor. As the condenser, side panel, and compressor of the refrigerator all generate high temperatures during operation, the cold airflow in the airflow cavity 340 is directed to one or more of the condenser, side panel, and compressor via the flow guide 400 to cool them, thereby improving the refrigerator's cooling and heat dissipation performance.

[0073] Optionally, the heating element 500 includes a side panel, which is located on the side wall of the housing 100 and serves to enclose the press chamber. Thus, the side panel of the refrigerator is located on the side wall of the housing 100 and serves to enclose the press chamber. Due to the high temperature in the press chamber, the side panel may heat up, causing discomfort to the user. The cold airflow from the airflow cavity 340 is directed to the side panel via the air guide duct 400, thereby cooling the side panel. This reduces the ambient temperature in the press chamber and improves the user experience.

[0074] Combine Figure 9As shown, in some embodiments, a plurality of refrigeration compartments 110 are provided inside the cabinet 100, and a folding structure 300 is correspondingly provided below the opening of each refrigeration compartment 110. In this way, multiple refrigeration compartments 110 are provided inside the cabinet 100 to refrigerate and freeze food. The multiple refrigeration compartments 110 are closed by one or more doors 200. When the door 200 is opened, each refrigeration compartment 110 may leak cold air. Therefore, a folding structure 300 is correspondingly provided below the opening of each refrigeration compartment 110 to block the cold air flow overflowing from the refrigeration compartment 110, thereby reducing the cold air leakage of the entire refrigerator and reducing the energy consumption of the refrigerator.

[0075] Optionally, multiple refrigeration compartments 110 are arranged in a vertical direction. In this way, the folding structure 300 of the upper refrigeration compartment 110 among adjacent refrigeration compartments 110 can block the opening area of ​​the lower refrigeration compartment 110, further reducing the occurrence of cold and heat convection and reducing the leakage of cold energy in the lower refrigeration compartment 110.

[0076] Optionally, a folding structure 300 is also provided above the opening of the topmost refrigeration compartment 110 among the multiple refrigeration compartments 110. In this way, the area above the opening of the topmost refrigeration compartment 110 can be shielded, reducing the occurrence of cold and heat convection and reducing the leakage of cold energy in the topmost refrigeration compartment 110.
