Description

Technical Field

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

[0002] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. With the improvement of people's living standards, people have higher requirements for the cleanliness and beauty of kitchen decoration. For this reason, built-in refrigerators are introduced on the market to embed refrigerators into cabinets to avoid the refrigerator being exposed and affecting the cleanliness and beauty of the kitchen.

[0003] At present, after the built-in refrigerator is embedded in the cabinet, if the left and right sides of the refrigerator are close to the cabinet or the gap is small, the refrigerator door will interfere with the cabinet during opening. Therefore, a wider distance is usually reserved between the left and right sides of the refrigerator and the cabinet. Although this can prevent the refrigerator from being exposed, the large distance between the left and right sides of the refrigerator and the cabinet will still affect the neatness and aesthetics of the kitchen decoration, resulting in a poor experience of the built-in refrigerator. Summary of the invention

[0004] An embodiment of the present invention provides a refrigerator, which solves the problem of poor user experience of built-in refrigerators in the prior art.

[0005] To achieve the above object, the embodiments of the present invention adopt the following technical solutions:

[0007] The refrigerator provided by the present application has a door body disposed at the opening of the storage chamber of the box body, and is used to open or close the opening of the storage chamber. The fixing member is fixed to one of the box body and the door body, and the rotating member is connected to the other of the box body and the door body. The rotating member has a second arc-shaped portion, and the rotating member can rotate around its rotation axis, thereby being able to drive the second arc-shaped portion to rotate around the rotation axis. The axis of the second arc-shaped portion is parallel to the rotation axis, so the second arc rotates eccentrically when rotating around the rotation axis. The fixing member has a first arc-shaped portion, and while the second arc-shaped portion rotates eccentrically around the rotation axis, it can also rotate around the axis of the first arc-shaped portion, and during this process, the second arc-shaped portion contacts the first arc-shaped portion.

[0008] The rotation of the second arc-shaped portion around the axis of the first arc-shaped portion can drive the door body to rotate relative to the box body, thereby enabling the door body to close or open the opening of the storage chamber, and, in this process, the second arc-shaped portion rotates around the rotation axis, and the second arc-shaped portion contacts the first arc-shaped portion, thereby enabling the door body to move toward or away from the first arc-shaped portion, that is, enabling the door body to move along the width direction of the refrigerator, thereby enabling the side of the refrigerator close to the box body to move toward the inner side of the refrigerator along the width direction of the refrigerator during the process of the door body opening the opening of the storage chamber.

[0054] Household refrigerators are usually placed in the kitchen to store food. In order to reduce and occupy the space of the kitchen and make the overall layout of the kitchen neater and more beautiful, people choose to embed the refrigerator in the cabinet when decorating the kitchen.

[0055] After the refrigerator is embedded in the cabinet, if the distance between the refrigerator and the cabinet on both sides in the width direction is small or zero, the refrigerator door will interfere with the cabinet during opening, resulting in a smaller opening angle of the refrigerator door, thereby affecting the user's use effect; if the refrigerator door is to be fully opened, it is necessary to make the distance between the refrigerator and the cabinet on both sides in the width direction larger, which will result in poor overall aesthetics of the refrigerator and the cabinet, and will also affect the user's use effect.

[0056] Based on this, the present application provides a refrigerator, such as Figure 1 As shown, the refrigerator includes a body 1 and a door body 2. A storage chamber 11 with an opening on one side is formed in the body 1. The storage chamber 11 is used to store food. The opening of the storage chamber 11 is used to take and put food. The door body 2 is arranged at the opening of the storage chamber 11 and is used to close or open the opening of the storage chamber 11.

[0057] It should be noted that the refrigerator may be a side-by-side refrigerator, a single-door refrigerator, a single-sided multi-door refrigerator, a double-sided multi-door refrigerator, etc.

[0058] like Figure 2 As shown, the refrigerator also includes a fixing part 3 and a rotating part 4. The fixing part 3 is fixed to one of the cabinet 1 and the door body 2, and the rotating part 4 is connected to the other of the cabinet 1 and the door body 2. The fixing part 3 and the rotating part 4 cooperate to open or close the door body 2.

[0059] It should be noted that the door body 2 is usually rotated around the opening of the storage chamber near the side wall of the box body 1 in the width direction to realize the opening and closing of the door body 2. Therefore, the fixing member 3 is usually installed at the upper end or lower end of one of the box body 1 and the door body 2, and the rotating member 4 is usually installed at the upper end or lower end of the other of the box body 1 and the door body 2, and the rotating member 4 and the fixing member 3 are both arranged at the side wall of the refrigerator near the refrigerator in the width direction.

[0060] For example, in some embodiments, Figure 2 As shown, the fixing member 3 is fixed to the box body 1, and the rotating member 4 is connected to the door body 2; in other embodiments, as Figure 3 As shown, the fixing member 3 is fixed on the door body 2 , and the rotating member 4 is connected to the box body 1 .

[0061] It should be noted that when the refrigerator has multiple door bodies 2, one door body 2 needs to correspond to at least one fixed part 3 and at least one rotating part 4, so that the door body 2 can be opened and closed through the cooperation of the at least one fixed part 3 and the at least one rotating part 4.

[0062] Here, an example is taken in which the fixing member 3 is fixed on the box body 1 and the rotating member 4 is connected to the door body 2 for description.

[0063] The rotating member 4 can rotate around its rotation axis, that is, the rotating member 4 can rotate relative to the door body 2, and the axis around which the rotating member 4 rotates is its rotation axis.

[0064] like Figure 4 As shown, the rotating member 4 has a second arc portion 41. When the rotating member 4 rotates around the rotation axis, the second arc portion 41 can be driven to rotate synchronously with the rotating member 4. Figure 4 ) and the axis of the second arc-shaped portion 41 (located at Figure 4 That is, the rotation axis does not coincide with the axis of the second arc-shaped portion 41, so the rotation of the second arc-shaped portion 41 around the rotation axis is eccentric rotation.

[0065] For example, in some embodiments, Figure 4 As shown, the rotating member 4 may include a fixed shaft 42 and a disk 43, the second arc portion 41 is the circumferential wall of the disk 43, the rotation axis is the axis of the fixed shaft 42, the rotation axis is parallel to the axis of the disk 43, the fixed shaft 42 is rotatably connected to the door body 2, the disk 43 is fixed on the fixed shaft 42, and the fixed shaft 42 rotates relative to the door body 2 to drive the disk 43 to rotate. At this time, the disk 43 rotates around the rotation axis, that is, the disk 43 rotates eccentrically, and the second arc portion 41 also rotates eccentrically.

[0066] Among them, the fixed shaft 42 can be cylindrical, or it can be divided into two sections, one section is cylindrical, and the other section is rectangular, irregular, etc. The cylindrical section is rotatably connected to the door body 2, and the other end is used to fix the disc 43.

[0067] In addition, the rotating member 4 can also include only the disc 43. In this case, the fixed shaft 42 can be fixed on the door body 2, and the disc 43 is rotatably connected to the fixed shaft 42, so that the axis of the disc 43 is parallel to the axis of the fixed shaft 42, and the rotation of the disc 43 around the fixed shaft 42 is eccentric rotation.

[0068] In other embodiments, Figure 5 As shown, the rotating member 4 may include a fixed shaft 42, a connecting rod 44 and an arc-shaped plate 45. The fixed shaft 42 may be fixed on the door body 2, one end of the connecting rod 44 is fixedly connected to the arc-shaped plate 45, and the other end of the connecting rod 44 is rotatably connected to the fixed shaft 42. The axis of the fixed shaft 42 is parallel to the axis of the arc-shaped plate 45. The connecting rod 44 rotates around the fixed shaft 42 to drive the arc-shaped plate 45 to rotate around the fixed shaft 42. At this time, the arc-shaped plate 45 rotates eccentrically. The second arc portion 41 may be the outer peripheral wall of the arc-shaped plate 45, and the second arc portion 41 rotates eccentrically.

[0069] In some other embodiments, Figure 6 As shown, the rotating member 4 may include a fixed shaft 42 and a cam 46. In this case, the second arc-shaped portion 41 may be the peripheral wall of the cam 46, the fixed shaft 42 may be fixed to the door body 2, and the cam 46 is rotatably connected to the fixed shaft 42. The axis of the base circle of the cam 46 is parallel to the axis of the fixed shaft 42. Then, the cam 46 rotates eccentrically around the fixed shaft 42, and the second arc-shaped portion 41 rotates synchronously with the cam 46, and the second arc-shaped portion 41 also rotates eccentrically.

[0070] The fixing member 3 has a first arc-shaped portion 31 . Specifically, the fixing member 3 may further include a fixing portion 32 and a fixing plate 33 . The fixing portion 32 is fixed on the box body 1 , and the fixing plate 33 is fixedly connected to the fixing portion 32 .

[0071] For example, in some embodiments, Figure 6 As shown, the fixing portion 32 is a fixing plate, the fixing disk 33 is semicircular, and the peripheral wall of the fixing disk 33 is the first arc portion 31; the fixing portion 32 and the fixing disk 33 can be an integral structure, or can be connected together by a connecting piece.

[0072] In other embodiments, Figure 7 As shown, the fixing portion 32 may be a fixing rod, the fixing disk 33 may be circular, and the peripheral wall of the fixing disk 33 is the first arc-shaped portion 31 .

[0073] When the rotating member 4 rotates around the rotation axis, it also rotates around the axis of the first arc-shaped portion 31, and the second arc-shaped portion 41 is in contact with the first arc-shaped portion 31. That is, when the rotating member 4 rotates around the rotation axis, it also rotates around the axis of the first arc-shaped portion 31, and when the rotating member 4 rotates around the rotation axis and around the axis of the first arc-shaped portion 31, the first arc-shaped portion 31 and the second arc-shaped portion 41 are always in contact.

[0074] The axial direction of the first arc-shaped portion 31 and the axial direction of the second arc-shaped portion 41 are both consistent with the height direction of the refrigerator, and the rotating member 4 is connected to the door body 2, and the fixing member 3 is fixedly connected to the box body 1. During the rotation of the rotating member 4 around the axis of the first arc-shaped portion 31, the door body 2 can be driven to rotate around the axis of the first arc-shaped portion 31, thereby driving the door body 2 to rotate relative to the box body 1, thereby driving the door body 2 to open or close the opening of the storage chamber 11.

[0075] At the same time, the rotating part 4 rotates around the rotation axis, which can drive the first arc-shaped portion 31 to rotate eccentrically around the rotation axis, and the first arc-shaped portion 31 is always in contact with the second arc-shaped portion 41, that is, the center distance between the first arc-shaped portion 31 and the second arc-shaped portion 41 needs to be kept unchanged. Then, while the door body 2 rotates around the axis of the first arc-shaped portion 31, it will move in the width direction of the refrigerator.

[0076] By reasonably setting the rotation direction of the rotating member 4, the rotation direction of the rotating member 4 around the axis of the first arc-shaped portion 31, and the position of the rotation axis and the axis of the second arc-shaped portion 41, it can be achieved that when the door body 2 opens the opening of the storage chamber 11, the side of the door body 2 close to the cabinet body 1 moves toward the inside of the refrigerator along the width direction of the refrigerator.

[0077] It should be noted that the side of the door body 2 close to the box body 1 refers to the side of the door body 2 close to the box body 1 when the door body 2 is opened; the inner side of the refrigerator refers to the side along the width direction of the refrigerator where the two side walls of the refrigerator are close to each other, and correspondingly, the side of the two side walls of the refrigerator facing away from each other is the outer side of the refrigerator.

[0078] For a refrigerator embedded in a cabinet, during the process of opening the storage chamber 11 through the door body 2, the side of the door body 2 close to the box body 1 moves toward the inside of the refrigerator along the width direction of the refrigerator, so that after the door body 2 is opened, only a small part of the orthographic projection of the door body 2 on the box body 1 is located on the outside of the box body 1 or all of it is located on the inside of the box body 1, thereby avoiding the phenomenon that the door body 2 interferes with the cabinet after opening, thereby increasing the opening angle of the door body 2 to improve the user experience.

[0079] Furthermore, since after the door body 2 is opened, only a small part of the orthographic projection of the door body 2 on the cabinet 1 is located on the outside of the cabinet 1 or all of it is located on the inside of the cabinet 1, the gap between the refrigerator and the cabinet on both sides in the width direction can be smaller or zero, thereby increasing the overall aesthetics of the refrigerator and the cabinet and further increasing the user's use effect.

[0080] The rotation of the rotating member 4 around the rotation axis and the rotation of the rotating member 4 around the axis of the first arc-shaped portion 31 can be achieved manually or driven by an electric power member. Here, the rotation of the rotating member 4 around the rotation axis and the rotation of the rotating member 4 around the axis of the first arc-shaped portion 31 are both achieved by driving an electric power member as an example for explanation.

[0081] Specifically, in some embodiments, Figure 8 As shown, the rotating member 4 includes a disc 43, and the refrigerator can also include a first power member 5, which includes a first motor 51 and a first connecting rod 52. The first motor 51 is fixed on the fixing member 3, and the fixing member 3 is fixed on the box body 1. The output shaft of the first motor 51 is fixedly connected to one end of the first connecting rod 52, and the axis of the output shaft of the first motor 51 coincides with the axis of the first arc-shaped portion 31. The second end of the first connecting rod 52 is fixedly connected to the rotating member 4, and the first motor 51 is driven to rotate the first connecting rod 52 around the output shaft of the first motor 51, so that the first connecting rod 52 drives the rotating member 4 to rotate around the output shaft of the first motor 51, that is, drives the rotating member 4 to rotate around the axis of the first arc-shaped portion 31.

[0082] The first power member 5 may further include a second motor 53, which is fixed to the door body 2, and an output shaft of the second motor 53 is fixedly connected to the rotating member 4, an axis of the output shaft of the second motor 53 coincides with the rotation axis of the rotating member 4, and the rotating member 4 is driven to rotate around the rotation axis by the operation of the second motor 53.

[0083] like Figure 8 As shown, the door body 2 is in an open state. When the door body 2 needs to be closed, the first motor 51 can drive the first connecting rod 52 to rotate clockwise (as shown in FIG. Figure 8 The rotating member 4 is driven to rotate clockwise around the axis of the first arc-shaped portion 31, thereby driving the door body 2 to rotate clockwise. At the same time, the rotating member 4 is driven to rotate clockwise or counterclockwise around the rotation axis by the second motor 53, so as to drive the door body 2 to move toward the outside of the refrigerator on the side close to the cabinet 1.

[0084] When the door 2 needs to be opened, it is only necessary to make the first motor 51 and the second motor 53 rotate in the opposite direction to that when the door 2 is closed, so that the door 2 can be opened and the side of the door 2 close to the box body 1 can be moved toward the inside of the refrigerator.

[0085] In other embodiments, the fixing member 3 is fixed on the box body 1, and the fixing member 3 includes a semicircular fixing disk 33, the first arc portion 31 is the peripheral wall of the fixing disk 33, and the rotating member 4 includes a fixing shaft 42 and a disk 43, and the second arc portion 41 is the peripheral wall of the disk 43.

[0086] like Fig. 9 As shown, a plurality of first gear teeth 311 are arranged at equal intervals along the circumference of the first arc portion 31, so that the first arc portion 31, the fixed disk 33 and the first gear teeth 311 form a gear; a plurality of second gear teeth 411 are arranged at equal intervals along the circumference of the second arc portion 41, so that the second gear teeth 411, the second arc portion 41 and the disk 43 also form a gear, and the plurality of first gear teeth 311 are meshed with the plurality of second gear teeth 411 to form a gear-to-gear meshing transmission structure.

[0087] The refrigerator can also include a motor 6, which is fixed to the door body 2. The output shaft of the motor 6 is fixedly connected to the fixed shaft 42, and the axis of the output shaft of the motor 6 can be made to coincide with the axis of the fixed shaft 42. The fixed shaft 42 is driven to rotate by the motor 6, thereby driving the disc 43 to rotate eccentrically around the fixed shaft 42. Since the second gear teeth 411 on the disc 43 are engaged with the first gear teeth 311 on the fixed disc 33, when the disc 43 rotates around the fixed shaft 42, the disc 43 is also caused to rotate around the axis of the fixed disc 33, and the first arc portion 31 and the second arc portion 41 are brought into contact through the engagement of the first gear teeth 311 and the second gear teeth 411.

[0088] At this time, since the disc 43 and the fixed disc 33 are meshed through the second gear teeth 411 and the first gear teeth 311, the rotation direction of the disc 43 will be the same as the rotation direction of the disc 43 around the axis of the fixed disc 33. Therefore, the rotation axis, i.e., the axis of the fixed shaft 42 and the axis of the disc 43 need to satisfy the following conditions: when the door body 2 closes the opening of the storage chamber 11, the rotation axis is located on the side of the axis of the second arc-shaped portion 41 close to the box body 1; when the door body 2 opens the opening of the storage chamber 11, the rotation axis is located on the side of the axis of the second arc-shaped portion 41 away from the box body 1.

[0089] In this way, when the door body 2 is opened, the side of the door body 2 close to the box body 1 moves toward the inside of the refrigerator along the width direction of the refrigerator to avoid interference with the cabinet after the door body 2 is opened, thereby increasing the opening angle of the door body 2 and improving the user's use effect.

[0090] In addition, the motor 6 drives the disc 43 to rotate, and the meshing transmission of the first gear 311 and the second gear 411 can realize automatic opening and closing of the door body 2, improve the degree of automation, and further improve the user's use effect.

[0091] For example, Fig. 9 As shown, the door body 2 is opened 90°, at which time the rotation axis (coincides with the axis of the output shaft of the motor 6) is located at the axis of the disk 43 ( Fig. 9 The middle P position) is away from the side of the box body 1.

[0092] like Fig.10 As shown, the door body 2 is opened 45°. At this time, the rotation axis (coincides with the axis of the output shaft of the motor 6) moves along the axis of the door body 2 toward the axis of the disk 43 ( Fig.10 The middle P position) moves closer to one side of the box 1.

[0093] like Fig.11 As shown, the door body 2 is closed, at this time, the rotation axis (coincides with the axis of the output shaft of the motor 6) is located at the axis of the disk 43 ( Fig.11 The middle P position) is close to one side of the box 1.

[0094] On this basis, in order to facilitate the spatial arrangement of the motor 6 and the disc 43, and to prevent the motor 6 from directly driving the disc 43 to cause the door body 2 to move too fast during the opening or closing process, thereby causing damage to the equipment, as shown in FIG. Fig.12 As shown, the refrigerator also includes a transmission member 7, which can fix the motor 6 on the door body 2 and is located on one side of the disc 43. The transmission member 7 is connected to the output shaft of the motor 6 and to the fixed shaft 42. The operation of the motor 6 drives the transmission member 7 to move, thereby driving the fixed shaft 42 to rotate through the transmission member 7, so as to drive the disc 43, the second arc-shaped portion 41 and the second gear 411 to rotate around the fixed shaft 42, wherein the axis of the fixed shaft 42 is the rotation axis of the rotating member 4.

[0095] For example, in some embodiments, Fig.12 As shown, the transmission member 7 includes a first gear 71 and a second gear 72. The first gear 71 is fixed to the output shaft of the motor 6, and the axis of the first gear 71 coincides with the axis of the output shaft of the motor 6; the second gear 72 is fixed to the fixed shaft 42, and the axis of the second gear 72 coincides with the axis of the fixed shaft 42, and the second gear 72 is meshed with the first gear 71.

[0096] The motor 6 drives the first gear 71 to rotate, and through the meshing relationship between the first gear 71 and the second gear 72, the first gear 71 drives the second gear 72 to rotate around the fixed shaft 42, thereby driving the disk 43 fixed on the second gear 72 to rotate.

[0097] Through the meshing transmission of the first gear 71 and the second gear 72, the process of the motor 6 driving the disc 43 to rotate can be relatively stable, so that the door body 2 can be relatively stable during the opening or closing process, thereby avoiding damage to the equipment during the opening or closing process of the door body 2.

[0098] Furthermore, the radial dimension of the second gear 72 can be made larger than the radial dimension of the first gear 71. Then, when the first gear 71 and the second gear 72 are able to mesh, the number of teeth of the second gear 72 will be larger than the number of teeth of the first gear 71, so that the second gear 72 can act as a decelerator, thereby reducing the rotation speed of the disk 43, and further reducing the opening or closing speed of the door body 2, further improving the stability of the opening or closing of the door body 2, and avoiding damage to the equipment during the opening or closing process of the door body 2.

[0099] In other embodiments, Fig.13 As shown, the transmission member 7 can also be a synchronous belt and synchronous wheel transmission structure. The specific transmission member 7 includes a first synchronous wheel 73, a second synchronous wheel 74 and a synchronous belt 75. The first synchronous wheel 73 is fixed to the output shaft of the motor 6, and the axis of the first synchronous wheel 73 coincides with the axis of the output shaft of the motor 6. The second synchronous wheel 74 is fixed to the fixed shaft 42, and the axis of the second synchronous wheel 74 coincides with the axis of the fixed shaft 42. The synchronous belt 75 is wound around the first synchronous wheel 73 and the second synchronous wheel 74. The disc 43 is fixed to the second synchronous wheel 74, and the axis of the disc 43 is parallel to the axis of the second synchronous wheel 74.

[0100] The first synchronous wheel 73 is driven to rotate by the motor 6 , thereby driving the second synchronous wheel 74 to rotate through the synchronous belt 75 , and further driving the disk 43 fixed on the second synchronous wheel 74 to rotate.

[0101] like Fig.14 and Fig.15 As shown, the refrigerator also includes a positioning assembly 8, which is connected to both the fixed disk 33 and the circular disk 43. The positioning assembly 8 is used to limit the relative positions of the fixed disk 33 and the circular disk 43 so that the second arc-shaped portion 41 and the first arc-shaped portion 31 can always be in contact during the rotation of the rotating member 4 around the rotation axis and the rotation around the axis of the first arc-shaped portion 31.

[0102] Specifically, in some embodiments, the rotating member 4 includes a fixed shaft 42 and a disk 43 , the second arc portion 41 is a peripheral wall of the disk 43 , the fixing member 3 includes a semicircular fixing disk 33 , and the first arc portion 31 is a peripheral wall of the fixing disk 33 .

[0103] like Fig.15 As shown, the positioning assembly 8 includes a first rotating shaft 81, a second rotating shaft 82 and a limiting member 83. The first rotating shaft 81 is fixed on the fixed disk 33, and the axis of the first rotating shaft 81 coincides with the axis of the fixed disk 33; the second rotating shaft 82 is fixed on the disk 43, and the axis of the second rotating shaft 82 coincides with the axis of the disk 43; the limiting member 83 includes a first connecting portion 831 and a second connecting portion 832 that are relatively arranged, the first connecting portion 831 is rotatably connected to the first rotating shaft 81, and the second connecting portion 832 is rotatably connected to the second rotating shaft 82.

[0104] By connecting the limit piece 83, the first rotating shaft 81 and the second rotating shaft 82, the center distance between the disk 43 and the fixed disk 33 can be limited. When the disk 43 rotates around the fixed shaft 42 and the fixed disk 33, the center distance between the disk 43 and the fixed disk 33 can be ensured to be always the same, thereby ensuring that the first arc portion 31 and the second arc portion 41 are always in contact.

[0105] Among them, the limiting member 83 can be a limiting rod, a limiting plate or a limiting frame, etc.; the limiting member 83 can also be an elastic component, such as a spring, rubber, etc. At this time, the elastic force generated by the limiting member 83 on the disc 43 and the fixed disc 33 causes the disc 43 and the fixed disc 33 to squeeze each other.

[0106] The first connection part 831 can be a rotating hole opened on the limit member 83, or it can be a rotating cylinder, bearing, etc. arranged on the limit member 83; the second connection part 832 can be a rotating hole opened on the limit member 83, or it can be a rotating cylinder, bearing, etc. arranged on the limit member 83.

[0107] In other embodiments, Fig.16 As shown, the rotating member 4 includes a fixed shaft 42 and a disk 43 , the second arc portion 41 is the peripheral wall of the disk 43 , the fixing member 3 includes a semicircular fixing disk 33 , and the first arc portion 31 is the peripheral wall of the fixing disk 33 .

[0108] The positioning assembly 8 includes an arc-shaped extrusion plate 84, a first elastic member 85 and a third rotating shaft 86. The extrusion plate 84 is slidably connected to the door body 2 and is located on the side of the disc 43 away from the fixed disc 33. The inner circumferential wall of the extrusion plate 84 abuts against the circumferential wall of the disc 43. The third rotating shaft 86 is fixed on the fixed disc 33, and the axis of the third rotating shaft 86 coincides with the axis of the fixed disc 33. One end of the first elastic member 85 is rotatably connected to the third rotating shaft 86, and the other end of the first elastic member 85 is connected to the extrusion plate 84. The first elastic member 85 generates an extrusion force on the extrusion plate 84 toward the fixed plate.

[0109] When the disk 43 rotates around the fixed shaft 42 and around the axis of the fixed disk 33, the first elastic member 85 tightens the extrusion plate 84, so that the extrusion plate 84 squeezes the disk 43, so that the disk 43 abuts against the fixed disk 33, and the first arc portion 31 and the second arc portion 41 are always in contact.

[0110] The first elastic member 85 may be a spring, rubber or the like.

[0111] In some other embodiments, Fig.17As shown, the rotating member 4 includes a fixed shaft 42 and a cam 46 , the second arc portion 41 is the peripheral wall of the cam 46 , the fixing member 3 includes a semicircular fixing disk 33 , and the first arc portion 31 is the peripheral wall of the fixing disk 33 .

[0112] The positioning assembly 8 includes a first rotating shaft 81, a second rotating shaft 82 and a second elastic member 87. The first rotating shaft 81 is fixed on the fixed disk 33, and the axis of the first rotating shaft 81 coincides with the axis of the fixed disk 33; the second rotating shaft 82 is fixed on the disc 43, and the axis of the second rotating shaft 82 coincides with the axis of the disc 43; one end of the second elastic member 87 is rotatably connected to the first rotating shaft 81, and the other end of the second elastic member 87 is rotatably connected to the second rotating shaft 82. The elastic force generated by the second elastic member 87 on the cam 46 and the fixed disk 33 causes the cam 46 and the fixed disk 33 to squeeze each other.

[0113] When the cam 46 rotates around the fixed shaft 42 and around the axis of the fixed disk 33, the cam 46 is tightened by the second elastic member 87, so that the cam 46 squeezes the fixed disk 33, so that the wheel abuts against the fixed disk 33, and the first arc portion 31 and the second arc portion 41 are always in contact.

[0114] The second elastic member 87 may be a spring, rubber or the like.

[0115] like Fig.18 As shown, the refrigerator also includes a guide assembly 9, which is used to guide the movement path of the door body 2 when the fixed part 3 and the rotating part 4 cooperate to open or close the door body 2, so as to avoid jamming of the door body 2 and make the opening or closing of the door body 2 more stable and smoother.

[0116] Specifically, Fig.19 As shown, the guide assembly 9 includes a first path guide 91 and a first sliding member 92 , and / or the guide assembly 9 includes a second path guide 93 and a second sliding member 94 .

[0117] The first path guide 91 is disposed on the door body 2 , and is used to guide the door body 2 to rotate around the axis of the first arc-shaped portion 31 ; the first sliding member 92 is fixedly connected to the box body 1 , and the first sliding member 92 is slidably connected to the first path guide 91 .

[0118] Since the trajectory formed by the door body 2 rotating around the axis of the first arc-shaped portion 31 is an arc, the first path guide 91 is also an arc.

[0119] For example, in some embodiments, Fig.19As shown, the first path guide 91 can be an arc-shaped groove, the first sliding member 92 can be a first sliding guide column, a mounting plate 95 is fixed on the refrigerator body 1, one end of the first sliding guide column is fixed on the mounting plate 95, and the other end of the first sliding guide column extends into the arc-shaped groove and can slide in the arc-shaped groove; and because the first sliding guide column is cylindrical, the first sliding guide column can rotate while sliding in the arc-shaped groove.

[0120] In other embodiments, Fig. 20 As shown, the first path guide 91 can also be an arc-shaped guide rail, and the first sliding member 92 can be a first slider. A mounting plate 95 is fixed on the refrigerator body 1, one end of the first slider is rotatably connected to the mounting plate 95, and the other end of the first slider is slidably connected to the arc-shaped guide rail. When the first slider slides relative to the arc-shaped guide rail, it can also rotate relative to the mounting plate 95.

[0121] During the rotation of the door body 2 around the axis of the first arc-shaped portion 31, the first path guide 91 will rotate synchronously with the door body 2, so that the first sliding member 92 and the first path guide 91 will slide relative to each other. At the same time, the first sliding member 92 and the first path guide 91 will also rotate relative to each other, thereby limiting the rotation trajectory of the door body 2 to prevent the door body 2 from running off track or getting stuck during the rotation process, thereby avoiding affecting the opening or closing of the door body 2, and ensuring the stability and smoothness of the door body 2 during the opening or closing process.

[0122] The second path guide 93 is arranged on the door body 2, and the first path guide 91 is used to guide the door body 2 to move along the width direction of the refrigerator; the second sliding member 94 is fixedly connected to the box body 1, and the second sliding member 94 is slidably connected to the second path guide 93.

[0123] Since the trajectory formed by the door body 2 moving along the width direction of the refrigerator is a straight line, the second path guide 93 is also a straight line.

[0124] For example, in some embodiments, Fig.19 As shown, the second path guide 93 can be a linear groove, the second sliding member 94 can be a second sliding guide column, a mounting plate 95 is fixed on the refrigerator body 1, one end of the second sliding guide column is fixed on the mounting plate 95, and the other end of the second sliding guide column extends into the linear groove and can slide in the linear groove, and because the second sliding guide column is cylindrical, the second sliding guide column can rotate while sliding in the linear groove.

[0125] In other embodiments, Fig. 20As shown, the second path guide 93 can be a linear guide rail, the second sliding member 94 can be a second slider, a mounting plate 95 is fixed on the refrigerator body 1, one end of the second slider is rotatably connected to the mounting plate 95, and the other end of the second slider is slidably connected to the linear guide rail; when the second slider slides relative to the linear guide rail, it can also rotate relative to the mounting plate 95.

[0126] During the movement of the door body 2 along the width direction of the refrigerator, the second path guide 93 will rotate synchronously with the door body 2 and move along the width direction of the refrigerator, thereby causing the second sliding member 94 and the second path guide 93 to slide relative to each other. At the same time, the second sliding member 94 and the second path guide 93 will also rotate relative to each other, thereby limiting the movement trajectory of the door body 2 to prevent the door body 2 from running off track or getting stuck during movement, thereby avoiding affecting the opening or closing of the door body 2, and further ensuring the stability and smoothness of the door body 2 during the opening or closing process.

[0127] On this basis, the refrigerator has a first side and a second side in the height direction thereof, for example, the first side is the upper side of the refrigerator, and the second side is the lower side of the refrigerator.

[0128] The number of fixed parts 3 and the number of rotating parts 4 can both be two, wherein one fixed part 3 and one rotating part 4 are arranged on the first side of the refrigerator, and the other fixed part 3 and the other rotating part 4 are arranged on the second side of the refrigerator; at this time, the number of guide components 9 can be one, and the guide component 9 is arranged on the first side or the second side of the refrigerator; the number of guide components 9 can also be two, and one guide component 9 is arranged on the first side of the refrigerator, and the other guide component 9 is arranged on the second side of the refrigerator, so that the upper and lower ends of the door body 2 can be guided at the same time by the two guide components 9, so as to further improve the stability and smoothness of the door body 2 during opening or closing.

[0129] The number of the fixing members 3 and the number of the rotating members 4 may both be one, and then one fixing member 3 and one rotating member 4 are both arranged on the first side or both are arranged on the second side.

[0130] In this case, the number of guide components 9 can be two, one guide component 9 is arranged on the first side of the refrigerator, and the other guide component 9 is arranged on the second side of the refrigerator, so that the upper and lower ends of the door body 2 can be guided simultaneously by the two guide components 9 to further improve the stability and smoothness of the door body 2 during opening or closing.

[0131] In addition, in this case, the number of guide components 9 can also be one, and the guide component 9 and the fixed component 3 and the rotating component 4 need to be arranged on the first side and the second side of the refrigerator relative to each other, that is, the guide component 9 is arranged on the first side of the refrigerator, and the fixed component 3 and the rotating component 4 are arranged on the second side of the refrigerator; if the guide component 9 is arranged on the second side of the refrigerator, the fixed component 3 and the rotating component 4 are arranged on the first side of the refrigerator.
