Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] The current double-door or multi-door refrigerator usually includes a box body with a refrigerating compartment, and a first door body and a second door body for opening and closing the refrigerating compartment. A flip beam is usually provided on one side of the first door body, and the flip beam can rotate relative to the first door body. When the first door body and the second door body are in a closed state, the flip beam rotates to be parallel to the first door body to seal the joint between the first door body and the second door body, thereby improving the sealing of the refrigerating compartment.

[0003] In the related art, the end of the flip beam is usually provided with a first guide member that is slidable along its extension direction and has a restoring force. A second guide member is usually provided on the inner side of the box body, and the second guide member is provided with a guide groove. When closing the first door body, a thrust is applied to the first door body, and the first door body drives the flip beam to rotate toward the box body, and the first guide member located at the end of the flip beam slides into the guide groove of the second guide member. Under the guiding action of the guide groove, the first guide member drives the flip beam to rotate parallel to the first door body. When opening the first door body, a pulling force is applied to the first door body, and the first door body drives the flip beam to rotate away from the box body, and the first guide member slides out of the guide groove. Under the guiding action of the guide groove, the first guide member drives the flip beam to rotate perpendicular to the first door body.

[0004] However, if the flip beam is directly pulled when opening the first door body, the first door body cannot be opened, and even a technical problem of damaging the flip beam may occur. Utility Model Content

[0005] The embodiment of the present application provides a refrigerator that can solve the technical problem that if the flip beam is directly pulled when opening the first door body, the first door body will not be able to be opened, and even the flip beam will be damaged.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0007] A box body is provided with a refrigeration compartment, and a take-in and put-out port connected to the refrigeration compartment is provided on the front side of the box body;

[0008] A first door body having a first side and a second side opposite to each other, the first side of the first door body being rotatably connected to the box body, and the first door body being used to open or close at least a portion of the access opening;

[0009] a flip beam rotatably connected to the second side of the first door body;

[0010] A first guide member, which is disposed at an end of the flip beam, and the first guide member is slidable relative to the flip beam along an extension direction of the flip beam;

[0011] an elastic member, connecting the first guide member and the flip beam, and used for applying a restoring force to the first guide member away from the flip beam;

[0012] A second guide member is arranged in the refrigeration room and is arranged opposite to the first guide member when the first door body is in a closed state. The second guide member is provided with a guide groove for the first guide member to slide. The guide groove has an opening toward the access opening. The guide groove extends from the opening in a direction away from the first door body and away from the access opening. A first guide surface is arranged in the guide groove. The first guide surface is opposite to the first guide member when the first door body is in a closed state and is located on a side of the first guide member facing the access opening. Along the direction of the second guide member pointing to the center of the access opening, the first guide surface is inclined toward the access opening.

[0013] In the refrigerator of the embodiment of the present application, when the first door body is in a closed state, the flip beam is parallel to the first door body. The first guide member located at the end of the flip beam is located in the guide groove and is arranged opposite to the first guide surface. When the first door body is opened, if the flip beam is directly pulled, the first guide member contacts the first guide surface. Continue to pull the flip beam, the first guide surface can apply a first reaction force to the first guide member, and the component force of the first reaction force can make the first guide member slide relative to the flip beam in a direction away from the second guide member. Further pull the flip beam, the flip beam can leave the guide groove, the first door body can be opened, and damage to the flip beam can be avoided as much as possible.

[0014] In some embodiments of the present application, the first guide surface is a first guide plane.

[0015] With such arrangement, the processing method of the first guide plane is simpler than that of the first guide arcuate surface, thereby reducing the processing difficulty of the guide block.

[0016] In some embodiments of the present application, the box body includes a box front wall located at the front side, and an angle θ is formed between the first guide plane and the box front wall; the friction coefficient of the first guide surface is f; the restoring force is F 弹 , the tensile force on the flip beam is F 拉 ; Wherein, the angle θ is less than 90° and satisfies:

[0017]

[0018] With such arrangement, the angle θ is within the numerical range, which is beneficial to ensure that the first guide member slides along the first guide surface.

[0019] In some embodiments of the present application, the second guide member is also provided with a second guide surface, and the second guide surface is located on the side of the opening away from the first door body when the first door body is in a closed state; along the direction of the second guide member pointing to the center of the taking and releasing port, the second guide surface is inclined toward the direction away from the taking and releasing port.

[0020] With such arrangement, when the second door body is in an open state, if the flip beam rotates to be parallel to the first door body due to erroneous operation or other reasons, the first door body is closed at this time. Applying a thrust to the first door body, the first door body can drive the flip beam to rotate in the direction of the box body. The first guide member located at the end of the flip beam contacts the second guide surface. Continue to push the first door body, and the second guide surface can apply a second reaction force to the second guide member. The component of the second reaction force can cause the first guide member to slide relative to the flip beam in a direction away from the second guide member. The second guide member can cause the elastic member to deform. Further pushing the first door body, the flip beam can enter the guide groove, the elastic member restores its deformation, and the first door body can be closed.

[0021] In some embodiments of the present application, the second guide surface is a second guide plane.

[0022] With such arrangement, the second guide plane surface can be processed more simply than the second guide arc surface, thereby reducing the processing difficulty of the guide block.

[0023] In some embodiments of the present application, the box body includes a box liner for constructing the refrigeration compartment, and the inner side wall of the box liner is provided with a mounting groove, and the mounting groove is arranged opposite to the first guide member when the first door body is in a closed state; the second guide member is installed in the mounting groove.

[0024] With such arrangement, the side wall of the mounting groove can position the second guide member, thereby improving the relative position accuracy between the second guide member and the box liner, and preventing the second guide member from positional displacement as much as possible, which is beneficial to ensuring the accuracy of the movement trajectory of the first guide member and the flip beam.

[0025] In some embodiments of the present application, at least one positioning recess is provided on the bottom wall of the installation groove; at least one positioning protrusion is provided on the side of the second guide member facing the bottom wall of the installation groove, at least one positioning protrusion is provided in a one-to-one correspondence with at least one positioning recess, and each positioning protrusion is inserted into the corresponding positioning recess.

[0026] With such arrangement, the second guide member and the bottom wall of the mounting groove can be positioned by means of mutually inserted positioning protrusions and positioning recesses, thereby improving the relative position accuracy between the second guide member and the box liner and improving the connection strength between the second guide member and the box liner.

[0027] In some embodiments of the present application, a accommodating space is provided in the flip beam, a sliding through hole is provided at the end of the flip beam, and the sliding through hole is connected to the accommodating space; the first guide member is slidably disposed in the sliding through hole.

[0028] With such arrangement, the hole wall of the sliding through hole can constrain and guide the first guide member, so as to prevent the first guide member from deflecting as much as possible during the sliding process relative to the flip beam.

[0029] In some embodiments of the present application, a support column is provided at one end of the first guide member facing the accommodating space; a second connecting portion is provided in the accommodating space, and the second connecting portion is located on the side of the support column facing away from the sliding through hole; the elastic member is a compression spring, and the compression spring is located in the accommodating space, one end of the compression spring abuts against the second connecting portion, and the other end of the compression spring is sleeved on the support column and abuts against the first guide member.

[0030] With such an arrangement, the support column can support the compression spring, thereby preventing the compression spring from being severely deflected during deformation as much as possible, which is beneficial to improving the directional accuracy of the restoring force provided by the compression spring.

[0077] The refrigerator in the related art has a technical problem that if the flip beam is directly pulled when opening the first door body, the first door body cannot be opened, and even the flip beam is damaged. The inventor has found that the reason is that when the first door body is in a closed state, the flip beam rotates to be parallel to the first door body, and the first guide member is located in the guide groove. When opening the first door body, if the flip beam is directly pulled, the side wall of the guide groove blocks the first guide member, so that the first guide member cannot slide out of the guide groove, thereby making the first door body unable to open. When the pulling force applied to the flip beam is too large, it may even damage the flip beam, which has a negative impact on the sealing performance of the refrigerator.

[0078] In view of this, an embodiment of the present application provides a refrigerator, wherein a first guide surface is arranged in a guide groove, and the first guide surface is opposite to the first guide member when the first door body is in a closed state, and is located on the side of the first guide member facing the access opening. In the process of pulling the flip beam to open the first door body in a closed state, the first guide member slides relative to the flip beam in a direction away from the second guide member under the push of the first guide surface to leave the guide groove, so that the first door body can be opened, and damage to the flip beam can be avoided as much as possible, which is conducive to ensuring the sealing performance of the refrigerator.

[0079] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application.

[0086] In the description of this application, the "front side" refers to the side of the refrigerator facing the user when the refrigerator is normally used, and the "rear side" refers to the side of the refrigerator opposite to the "front side".

[0087] refer to Figure 1 and Figure 2 , an embodiment of the present application provides a refrigerator, which may include a box body 100 and a door body 200. The box body 100 may be configured with a refrigeration compartment 110 for placing food and other items. The refrigeration compartment 110 may have a take-out port 120. The take-out port 120 may be provided on the front side of the refrigeration compartment 110. For example, the front side of the box body 100 may be provided with the take-out port 120, and the take-out port 120 may be connected to the refrigeration compartment 110. A user may place an item in the refrigeration compartment 110 via the take-out port 120, or take an item out of the refrigeration compartment 110 via the take-out port 120. The door body 200 may be used to open or close the take-out port 120. The refrigerator may also include a refrigeration system, which may be used to provide coldness for the refrigeration compartment 110.

[0088] For example, reference Figure 2 The box body 100 may include a box liner 130 and a box shell 140. The box liner 130 may be configured with a refrigeration compartment 110. The box shell 140 may be connected to the outside of the box liner 130 to form the appearance of the refrigerator. The box body 100 may also include a box insulation layer, which may be disposed between the box liner 130 and the box shell 140. The box insulation layer can insulate the refrigeration compartment 110 to minimize the heat exchange between the refrigeration compartment 110 and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator.

[0089] The box body 100 may include a box front wall 150 located at the front side. The box front wall 150 may be formed with a take-out opening 120. Exemplarily, the box front wall 150 may be a side wall of the box housing 140 located at the front side of the refrigerator. Alternatively, the box front wall 150 may include a first side 231 wall of the box housing 140 located at the front side of the refrigerator, and a second side 232 wall adjacent to the take-out opening 120 in the box liner 130, and the second side 232 wall may be in contact with the first side 231 wall.

[0090] The box body 100 may further include a box rear wall located at the rear side of the refrigerator. The box rear wall may be arranged opposite to the box front wall 150. Exemplarily, the box rear wall may be a side wall of the box housing 140 located at the rear side of the refrigerator.

[0091] The refrigerator may also include two box side walls respectively located on both sides of the refrigerator. The two box side walls may be arranged relative to each other, and each box side wall is connected to the box front wall 150 and the box rear wall. Exemplarily, the box side wall may be the side wall of the box housing 140 located on the left or right side of the refrigerator.

[0092] For example, there may be more than one refrigeration compartment 110. Figure 1 and Figure 2 As shown, there can be three refrigeration compartments 110. One of the refrigeration compartments 110 can be located at the upper part of the cabinet 100. The other two refrigeration compartments 110 can be located at the lower part of the cabinet 100 and arranged side by side in the horizontal direction. The horizontal direction can refer to Figure 2 The direction x is shown in .

[0093] Exemplarily, one refrigeration compartment 110 located at the upper part of the box 100 can be set as a refrigerator. Two refrigeration compartments 110 located at the lower part of the box 100 can be set as freezer compartments. The internal temperature of the refrigerator compartment can be maintained between about 0°C and 5°C, and the items placed therein can be stored in a refrigerated mode. The internal temperature of the freezer compartment can be maintained between about -30°C and 0°C, and the items placed therein can be stored in a frozen mode.

[0094] It is understandable that the multiple refrigeration compartments 110 may also be arranged in other ways, and the refrigeration compartment 110 may be set as a refrigerator or a freezer. In some possible implementations, the refrigeration compartment 110 may also be set as a variable temperature room whose internal temperature changes in real time, which will not be described in detail in the present embodiment.

[0095] The door body 200 can be rotatably connected to the cabinet 100 to close or open the refrigeration compartment 110 corresponding thereto. Exemplarily, the door body 200 can include a door liner 210 and a door shell 220. The door liner 210 can face the refrigeration compartment 110 when the door body 200 is in a closed state. The door shell 220 can be connected to the outer side of the door liner 210 to form the appearance of the refrigerator. The door shell 220 can be rotatably connected to the cabinet 100. The door body 200 can also include a door insulation layer, which can be arranged between the door liner 210 and the door shell 220. The door insulation layer can keep the refrigeration compartment 110 warm to minimize the heat exchange between the refrigeration compartment 110 and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator.

[0096] The door body 200 may include a door front wall. The door front wall may be parallel to the box front wall 150 when the door body 200 is in a closed state. The door body 200 may also include a door rear wall arranged opposite to the door front wall. When the door body 200 is in a closed state, the door rear wall may be closer to the box body 100 than the door front wall. The door body 200 may also include two door side walls. The two door side walls may be arranged opposite to each other and may be connected to the door front wall and the door rear wall. The door body 200 may also include a door top wall. The door top wall may be located above the door front wall, the door rear wall and the two door side walls, and may be connected to the door front wall, the door rear wall and the two door side walls. The door body 200 may also include a door bottom wall. The door bottom wall may be located below the door front wall, the door rear wall and the two door side walls, and may be connected to the door front wall, the door rear wall and the two door side walls.

[0097] The refrigerator of the embodiment of the present application may further include a door seal (not shown in the drawings), which may be provided on the side of the door liner 210 facing the refrigerating compartment 110 when the door body 200 is in a closed state. For example, a fixing groove 211 may be provided on the side of the door liner 210 facing the refrigerating compartment 110 when the door body 200 is in a closed state, and the fixing groove 211 may be used for the door seal to be engaged. When the door body 200 is in a closed state, the door seal may abut against the front wall 150 of the box body 100 to seal the refrigerating compartment 110, which is conducive to ensuring the refrigeration effect of the refrigerator.

[0098] The number of door bodies 200 may be set corresponding to the number of refrigeration compartments 110. For example, one refrigeration compartment 110 may be correspondingly provided with one door body 200. Figure 1 and Figure 2 As shown, for the two refrigeration compartments 110 located at the lower part of the cabinet 100, each refrigeration compartment 110 may be provided with a corresponding door body 200. The door body 200 may be rotatably connected to the cabinet 100 to close or open the refrigeration compartment 110 corresponding thereto.

[0099] For example, one refrigeration compartment 110 may also be provided with two door bodies 200. Figure 1 and Figure 2 As shown, for a refrigeration compartment 110 located at the upper part of the box 100, the refrigeration compartment 110 can be correspondingly provided with two door bodies 200. Both door bodies 200 are rotatably connected to the box 100, and the two door bodies 200 can rotate in opposite directions to open or close the refrigeration compartment 110.

[0100] The refrigerator of the embodiment of the present application may further include a flip beam 300, which may be rotatably connected to one of the two door bodies 200. The flip beam 300 may seal the joint of the two door bodies 200 when the two door bodies 200 are in a closed state, thereby improving the sealing of the refrigeration compartment 110, which is beneficial to improving the refrigeration effect of the refrigerator.

[0101] Hereinafter, the door body 200 connected to the flip beam 300 may be referred to as a first door body 230 , and the other door body 200 may be referred to as a second door body.

[0102] In the process of closing the first door body 230 and the second door body, a thrust may be applied to the first door body 230 first, and the first door body 230 may drive the flip beam 300 to rotate toward the box body 100. When the first door body 230 is in a closed state, the flip beam 300 may rotate to be parallel to the first door body 230. Then a thrust may be applied to the second door body, and the second door body may rotate toward the box body 100. When the second door body is in a closed state, the flip beam 300 seals the joint between the first door body 230 and the second door body. For example, the flip beam 300 may abut against the door seal strip connected to the first door body 230 and the door seal strip connected to the second door body.

[0103] In the process of opening the first door body 230 and the second door body, a pulling force may be first applied to the second door body, and the second door body may rotate in a direction away from the cabinet 100, and the second door body is in an open state. Then a pulling force may be applied to the first door body 230, and the first door body 230 may drive the flip beam 300 to rotate in a direction away from the cabinet 100. When the first door body 230 is in an open state, the flip beam 300 may rotate to be perpendicular to the first door body 230, thereby releasing the seal of the refrigeration compartment 110.

[0104] It should be noted that the flip beam 300 is parallel to the first door body 230, which means that the surface of the flip beam 300 that contacts the door seal is parallel to the front wall of the first door body 230. The flip beam 300 is perpendicular to the first door body 230, which means that the surface of the flip beam 300 that contacts the door seal is perpendicular to the front wall of the first door body 230.

[0105] refer to Figure 3 and Figure 4 The first door body 230 may have a first side 231 and a second side 232 opposite to each other, and the first side 231 of the first door body 230 may be rotatably connected to the box body 100. The first door body 230 may be used to open or close at least a portion of the access opening 120. The flip beam 300 may be rotatably connected to the second side 232 of the first door body 230.

[0106] For example, the flip beam 300 may be rotatably connected to the first door body 230 via a fixing member 310. Figure 4 As shown, a connecting protrusion 212 may be provided on a side of the door inner liner 210 of the first door body 230 facing away from the door housing 220 . The fixing member 310 may connect the flip beam 300 and the connecting protrusion 212 .

[0107] The fixing member 310 may include a fixed connection portion 311 and a rotation connection portion 312 connected to each other. The fixed connection portion 311 may be fixedly connected to the connection protrusion 212. For example, the connection protrusion 212 may be provided with a connection hole 213, and the fixed connection portion 311 may be snapped into the connection hole 213. The rotation connection portion 312 may be rotationally connected to the flip beam 300 around the extension direction of the flip beam 300, and the extension direction of the flip beam 300 may be Figure 4 The rotation connection part 312 may be a columnar structure extending along the direction z. A rotation recessed part extending along the direction z may be provided in the flip beam 300, and a mounting channel connected to the outside of the flip beam 300 may be provided in the rotation recessed part. The columnar structure may be inserted into the rotation recessed part and may rotate in the rotation recessed part. The partially fixed connection part 311 may be inserted into the mounting channel and connected to the columnar structure.

[0108] It is understandable that the flip beam 300 can also be rotatably connected to the first door body 230 through other structures such as hinges, etc., and this embodiment of the present application will not be described in detail.

[0109] like Figure 3 and Figure 4 As shown, and refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The refrigerator of the embodiment of the present application may further include a first guide member 400, which may be disposed at the end of the flip beam 300. The refrigerator may further include a second guide member 500, which may be disposed in the refrigeration compartment 110 and is disposed opposite to the first guide member 400 when the first door body 230 is in a closed state. The second guide member 500 may be provided with a guide groove 510, which may have an opening 511 toward the access opening 120, and the guide groove 510 may extend from the opening 511 in a direction away from the first door body 230 and away from the access opening 120.

[0110] During the process of closing the first door body 230, a thrust may be applied to the first door body 230, and the first door body 230 may drive the flip beam 300 to rotate toward the box body 100, and the first guide member 400 may enter the guide groove 510 through the opening 511, and the first guide member 400 may slide along the extension direction of the guide groove 510 to drive the flip beam 300 to rotate to be parallel to the first door body 230. During the process of opening the first door body 230, a pulling force may be applied to the first door body 230, and the first door body 230 may drive the flip beam 300 to rotate in a direction away from the box body 100, and the first guide member 400 may slide toward the opening 511 along the extension direction opposite to the guide groove 510, and the first guide member 400 may drive the flip beam 300 to rotate to be perpendicular to the first door body 230, and the first guide member 400 leaves the guide groove 510 through the opening 511.

[0111] From the above process of closing and opening the first door body 230, it can be known that the first guide member 400 is provided at the end of the flip beam 300, and the second guide member 500 is provided in the refrigeration compartment 110. The second guide member 500 is provided with a guide groove 510 for the first guide member 400 to slide. The guide groove 510 can guide the flip beam 300 through the first guide member 400, so that the flip beam 300 automatically rotates to be parallel to the first door body 230 during the process of closing the first door body 230, and automatically rotates to be perpendicular to the first door body 230 during the process of opening the first door body 230. There is no need to manually flip the flip beam 300, which improves the convenience when closing the first door body 230.

[0112] refer to Figure 6 and Figure 7 The inner side wall of the box liner 130 may be provided with a mounting groove 131, and the mounting groove 131 may be arranged opposite to the first guide member 400 when the first door body 230 is in a closed state. The second guide member 500 may be installed in the mounting groove 131. The groove side wall of the mounting groove 131 can position the second guide member 500, thereby improving the relative position accuracy between the second guide member 500 and the box liner 130, and preventing the second guide member 500 from being offset as much as possible, which is conducive to ensuring the accuracy of the motion trajectory of the first guide member 400 and the flip beam 300.

[0113] For example, the second guide member 500 can be fixed in the installation groove 131 by means of bolts, rivets or other connecting members. Figure 7 As shown, the bottom wall of the mounting groove 131 may be provided with at least one connecting through hole 132. Fig. 9As shown, at least one first connection portion 520 may be provided on one side of the second guide member 500 facing the bottom wall of the installation groove 131. The at least one first connection portion 520 is provided corresponding to the at least one connection through hole 132. The connection member may be provided in the connection through hole 132 on the side of the box liner 130 facing the box shell 140 and connected to the first connection portion 520.

[0114] like Figure 7 As shown, the bottom wall of the mounting groove 131 may be provided with at least one positioning recess 133. Fig. 9 As shown, at least one positioning protrusion 530 may be provided on one side of the second guide member 500 facing the bottom wall of the installation groove 131, and at least one positioning protrusion 530 is provided in one-to-one correspondence with at least one positioning recess 133, and each positioning protrusion 530 may be inserted into the corresponding positioning recess 133. The second guide member 500 and the bottom wall of the installation groove 131 may be positioned by the mutually inserted positioning protrusion 530 and the positioning recess 133, thereby improving the relative position accuracy between the second guide member 500 and the box liner 130, and improving the connection strength between the second guide member 500 and the box liner 130.

[0115] In some possible implementations of the present application, the opening 511 of the guide groove 510 may not be blocked by the second door body in the closed state. With such a configuration, during the process of closing or opening the refrigeration compartment 110, even if the second door body is in the closed state, the first guide member 400 may enter and exit the guide groove 510 via the opening 511, thereby preventing the second door body in the closed state from affecting the rotation process of the flip beam 300 as much as possible, so that the first door body 230 can still be opened or closed when the second door body is in the closed state. Therefore, during the process of closing or opening the refrigeration compartment 110, there is no requirement for the opening and closing sequence of the first door body 230 and the second door body, which improves the convenience of opening or closing the refrigeration compartment 110 and enhances the user experience.

[0116] Specifically, in the process of closing the refrigeration compartment 110, a thrust may be applied to the first door body 230 first, and the first door body 230 may drive the flip beam 300 to rotate toward the box body 100. The first guide member 400 may enter the guide groove 510 through the opening 511, and the first guide member 400 may slide along the extension direction of the guide groove 510, and the first guide member 400 may drive the flip beam 300 to rotate relative to the first door body 230 until the first door body 230 is in a closed state, and the flip beam 300 may rotate to be parallel to the first door body 230. Then, a thrust is applied to the second door body, and the second door body may rotate toward the box body 100 until the second door body is in a closed state, and the flip beam 300 may seal the joint between the first door body 230 and the second door body.

[0117] Alternatively, a thrust may be applied to the second door body first, and the second door body may rotate toward the box body 100 until the second door body is in a closed state. Then a thrust is applied to the first door body 230, and the first door body 230 may drive the flip beam 300 to rotate toward the box body 100, and the first guide member 400 may enter the guide groove 510 through the opening 511, and the first guide member 400 may slide along the extension direction of the guide groove 510, and the first guide member 400 may drive the flip beam 300 to rotate relative to the first door body 230 until the first door body 230 is in a closed state, and the flip beam 300 may rotate to be parallel to the first door body 230, so as to seal the joint between the first door body 230 and the second door body.

[0118] In the process of opening the refrigeration compartment 110, a pulling force may be first applied to the second door body, and the second door body may rotate in a direction away from the cabinet 100 until the second door body is in an open state. Then a pulling force is applied to the first door body 230, and the first door body 230 may drive the flip beam 300 to rotate in a direction away from the cabinet 100, and the first guide member 400 may slide in the guide groove 510 along the opposite extension direction of the guide groove 510, and the first guide member 400 may drive the flip beam 300 to rotate in the opposite direction relative to the first door body 230 until the first door body 230 is in an open state, and the flip beam 300 may rotate to be perpendicular to the first door body 230.

[0119] Alternatively, a pulling force may be applied to the first door body 230 first, so that the first door body 230 can drive the flip beam 300 to rotate in a direction away from the box body 100, and the first guide member 400 can slide in the guide groove 510 in the opposite direction of the guide groove 510, and the first guide member 400 can drive the flip beam 300 to rotate in the opposite direction relative to the first door body 230, until the first guide member 400 leaves the guide groove 510 through the opening 511, and the flip beam 300 rotates to be perpendicular to the first door body 230, and the first door body 230 is in an open state. Then, a pulling force is applied to the second door body, so that the second door body can rotate in a direction away from the box body 100, until the second door body is in an open state.

[0120] It should be noted that in some possible implementations of the embodiments of the present application, the opening 511 of the guide groove 510 may also be blocked by a small area of ​​the second door body in the closed state, as long as the second door body in the closed state does not interfere with the first guide member 400 entering and exiting the guide groove 510 through the opening 511.

[0121] refer to Fig.10 and Fig.11The first guide member 400 may be slidable relative to the flip beam 300 along the extension direction of the flip beam 300. The refrigerator may further include an elastic member 600, which may connect the first guide member 400 and the flip beam 300 to apply a restoring force to the first guide member 400 away from the flip beam 300. Figure 8 A first guide surface 540 may be provided in the guide groove 510. The first guide surface 540 may be opposite to the first guide member 400 when the first door body 230 is in a closed state, and is located on a side of the first guide member 400 close to the access opening 120. In the process of pulling the flip beam 300 to open the first door body 230 in a closed state, the first guide member 400 may slide along the first guide surface 540 relative to the flip beam 300 in a direction away from the second guide member 500 to leave the guide groove 510, so that the first door body 230 can be opened and damage to the flip beam 300 can be avoided as much as possible, which is conducive to ensuring the sealing performance of the refrigerator.

[0122] For example, reference Fig.12 , along the square of the second guide member 500 pointing to the center of the access opening 120, that is, along Fig.12 In the direction -z shown, the first guide surface 540 is inclined toward the access opening 120. That is, along the direction in which the second guide member 500 points to the center of the access opening 120, the distance between the first guide surface 540 and the box front wall 150 can be gradually reduced.

[0123] like Fig.12 As shown, when the first door body 230 is in a closed state, the flip beam 300 is parallel to the first door body 230. The first guide member 400 located at the end of the flip beam 300 is located in the guide groove 510 and is arranged opposite to the first guide surface 540. When the first door body 230 is opened, if the flip beam 300 is directly pulled, the first guide member 400 contacts the first guide surface 540. If the flip beam 300 is continuously pulled, the first guide surface 540 can apply a first reaction force F to the first guide member 400. R , the first reaction force F R The component force along the direction -z can make the first guide member 400 slide relative to the flip beam 300 in the direction away from the second guide member 500. At this time, the first guide member 400 can cause the elastic member 600 to deform. Further pulling the flip beam 300, the flip beam 300 can leave the guide groove 510, and the first door body 230 can be opened, and damage to the flip beam 300 can be avoided as much as possible. After the first door body 230 is opened, the elastic member 600 recovers its deformation, and the elastic member 600 applies a restoring force to the first guide member 400 away from the flip beam 300, so that the first guide member 400 is reset.

[0124] In some possible implementations of the embodiment of the present application, the first guide surface 540 may be a first guide arcuate surface.

[0125] In some other possible implementations of the embodiment of the present application, the first guide surface 540 may be a first guide plane. Compared with the first guide arc surface, the first guide plane is easier to process, thereby reducing the difficulty of processing the guide block.

[0126] like Fig.12 and Fig.13 As shown, an angle θ may be formed between the first guide plane and the plane where the front side of the box body 100 is located, that is, between the first guide plane and the box front wall 150. In some possible implementations of the present application embodiment, the angle θ may be greater than the sum of the arctangent value of the ratio of the restoring force to the pulling force on the flip beam 300 and the arctangent value of the ratio of the restoring force to the pulling force on the flip beam 300, and less than 90°. The angle θ is within this numerical range, which is conducive to ensuring that the first guide member 400 slides along the first guide surface 540.

[0127] Specifically, refer to Fig.14 , is the first reaction force F applied by the first guide surface 540 to the first guide member 400 R The first reaction force F R It can be decomposed into the vertical component F 1 and the horizontal component F to the left 2 . Vertical component F 1 The size of the elastic member 600 to the first guide member 400 can be 弹 The magnitude of the horizontal force F is equal. 2 The magnitude of the tension F applied to the first door body 230 may be 拉 The magnitude of the horizontal force F is equal. 2 With the first reaction force F R There may be an angle ψ between the normal line O of the first guide surface 540 and the first reaction force F R There can be an angle between

[0128] The friction coefficient of the first guide surface 540 may be f, and the friction angle of the first guide surface 540 may be Can be

[0129]

[0130] according to Fig.14 The geometric relationship shown in

[0131]

[0132] According to the friction angle theory of theoretical mechanics, the angle Need to be greater than the friction angle The first guide member 400 can slide along the first guide surface 540.

[0133]

[0134] From formula (1), formula (2) and formula (3), we can get

[0135]

[0136] That is, the angle θ may be greater than the sum of the arctangent of the friction coefficient of the first guide surface 540 and the arctangent of the ratio of the restoring force to the pulling force applied to the flip beam 300 .

[0137] In some possible implementations of the present application, the restoring force F 弹 The size can be

[0138] F 弹 =k·Δx (5);

[0139] k is the elastic coefficient of the elastic member 600, which may be 800 N / m. Δx is the pre-compression stroke of the elastic member 600, which may be 0.01 m. Then, the restoring force F 弹 It can be 8N.

[0140] Pull F 拉 It may be 35 N. The friction coefficient f of the first guide surface 540 may be 0.14.

[0141] In summary,

[0142] θ>20.85° (6);

[0143] It is understandable that when the elastic coefficient k of the elastic member 600, the pre-compression stroke Δx of the elastic member 600 and the friction coefficient f of the first guide surface 540 are other values, the angle θ can be greater than other values, and the embodiments of the present application will not elaborate on this one by one.

[0144] For example, reference Fig.11 , an accommodation space 320 may be provided in the flip beam 300. A sliding through hole 340 may be provided at the end of the flip beam 300, and the sliding through hole 340 may be connected to the accommodation space 320. The first guide member 400 may be slidably disposed in the sliding through hole 340. The hole wall of the sliding through hole 340 may constrain and guide the first guide member 400 to prevent the first guide member 400 from deflecting as much as possible during the sliding process relative to the flip beam 300.

[0145] For example, reference Fig.11, a support column 410 may be provided at one end of the first guide member 400 facing the accommodating space 320. A second connecting portion 330 may be provided in the accommodating space 320, and the second connecting portion 330 may be located on the side of the support column 410 facing away from the sliding through hole 340. The elastic member 600 may be a compression spring, and the compression spring may be located in the accommodating space 320. One end of the compression spring may abut against the second connecting portion 330, and the other end of the compression spring may be sleeved on the support column 410 and abut against the first guide member 400. The support column 410 may support the compression spring, and may prevent the compression spring from being severely deflected during deformation as much as possible, which is conducive to improving the directional accuracy of the restoring force provided by the compression spring.

[0146] like Figure 5 As shown, the second guide member 500 may also be provided with a second guide surface 550, and the second guide surface 550 may be located on a side of the opening 511 away from the first door body 230 when the first door body 230 is in a closed state. Figure 5 In the direction -z shown in FIG, the second guide surface 550 can be tilted away from the access port 120. That is, along the direction -z, the second guide surface 550 can be tilted toward the rear wall of the box.

[0147] When the second door body is in the open state, if the flip beam 300 rotates parallel to the first door body 230 due to erroneous operation or other reasons, the first door body 230 is closed at this time. Applying a thrust to the first door body 230, the first door body 230 can drive the flip beam 300 to rotate toward the box body 100. The first guide member 400 located at the end of the flip beam 300 contacts the second guide surface 550. Continue to push the first door body 230, and the second guide surface 550 can apply a second reaction force to the second guide member 500. The second reaction force has a component force along the direction -z, which can make the first guide member 400 slide relative to the flip beam 300 in a direction away from the second guide member 500. At this time, the second guide member 500 can cause the elastic member 600 to deform. Further push the first door body 230, the flip beam 300 can enter the guide groove 510, the elastic member 600 recovers its deformation, and the first door body 230 can be closed.

[0148] It can be seen from the above process that by setting the second guide surface 550 on the second guide member 500, the first door body 230 can be closed when the second door body is in an open state and when the flip beam 300 is parallel to the first door body 230. There is no need to adjust the flip beam 300 to be perpendicular to the first door body 230 before closing the first door body 230, thereby improving the convenience of closing the first door body 230.

[0149] In some possible implementations of the embodiment of the present application, the second guide surface 550 may be a second guide arc surface.

[0150] In some possible implementations of the embodiment of the present application, the second guide surface 550 may be a second guide plane. Compared with the second guide arc surface, the second guide plane is easier to process, thereby reducing the difficulty of processing the guide block.
