Wherein the arrangement direction of the first body side wall and the second body side wall is defined as a transverse direction; i.e. transverse to the direction from the first body side wall to the second body side wall or from the second body side wall to the first body side wall; also equivalent to the normal direction of the first body sidewall being transverse.
Wherein, the door front wall 31 and the door side wall 32 of the door body 30 intersect to form a first side edge W, and the door side wall 32 intersects with the door rear wall 33 to form a second side wall N. When the door 30 is closed, the first side edge W is located on a side of the second side edge N away from the case 10. The intersection line of the door front wall 31 and the door side wall 32 is a theoretical first side edge W (similarly, the theoretical second side edge N is an intersection line of the door side wall 32 and the door rear wall 33); in actual production and processing, the intersection of the door front wall 31 and the door side wall 32 is in rounded transition, so that a curved surface is formed at the intersection of the door front wall 31 and the door side wall 32; any straight line extending in the height direction of the door body 30 on the curved surface where the door front wall 31 intersects the door side wall 32 may represent the first side edge W (the same applies to the second side edge N). For convenience of description, the first side edge W and the second side edge N are described in theory, so as to illustrate the movement trend of the first side edge W or the second side edge N during the opening process of the door body 30. In addition, a plane passing through the centroid of the door body 30 and parallel to the door front wall 31 is denoted as a centroid plane P; during the opening of the door body 30, the centroid plane P moves with the door body 30, and the centroid plane P remains stationary with respect to the door body. In the present embodiment, the centroid plane P determined with the geometric center of the door body 30 as the centroid is described.
The back wall of the door body 30 is provided with a door seal 5; when the door body 30 is closed, the door seal 5 is attached to the front end face of the box body 10 surrounding the taking and placing opening, so that the joint of the door body 30 and the box body 10 is effectively sealed, the taking and placing opening is sealed by the door body 30, and the cold air is prevented from overflowing. The door sealing strip 5 is annular and can be arranged; the door seal 5 includes a side seal adjacent to the door side wall 32, and the edge of the door seal 5 (side seal) adjacent to the door side wall 32 and away from the door front wall 31 is denoted as a side seal edge H.
The hinge assembly includes a first hinge member and a second hinge member, the first hinge member being mated with the second hinge member and capable of relative rotation. The first hinge member is disposed on the case 10 and near the first body sidewall, and the second hinge member is disposed at an end of the door 30 near the first hinge member, and the first hinge member is matched with the second hinge member to allow the case 10 to rotate relative to the door 30. Wherein the second hinge member is adjacent to the door sidewall 32 of the door body 30; for example, when the first hinge member is located on the right side of the case 10, the right side of the door 30 is the door sidewall 32 when the door is closed; when the first hinge member is positioned on the left side of the case 10, the left side wall of the door body 30 is the door side wall 32 when the door body is closed.
Referring to fig. 2 to 4, the first hinge member includes: a hinge plate 40, and a plurality of hinge shafts formed on the hinge plate 40. Specifically, the hinge plate 40 includes a connection portion 401 connected to the case 10, and an extension portion 402 extending forward from the connection portion 401 and having a horizontal plate shape. The connection portion 401 may be fastened to the top wall of the case 10 by fasteners such as screws, pins, and bolts. Specifically, for the hinge at the upper end of the door 30, the connection portion 401 is connected to the top wall of the case 10. The hinge at the lower end of the door 30 is connected to the front end surface of the case 10 at a connecting portion 401. Wherein, the extension 402 of the first hinge member is formed with a first hinge shaft 41, a second hinge shaft 42 and a third hinge shaft 43; wherein the second hinge shaft 42 is located at a side of the first hinge shaft 41 near the first body sidewall, and the third hinge shaft 43 is located at a side of the first hinge shaft 41 far from the first body sidewall.

In the present embodiment, the first hinge shaft 41, the second hinge shaft 42, and the third hinge shaft 43 are formed on the extension portion 401 connected to the case 10 through the connection portion 401 to form a limiting shaft for guiding the movement of the door 30. Specifically, the first, second and third hinge shafts 41, 42 and 43 extend in a vertical direction (a height direction of the case 10) to be adapted to the guide portion 50 or 60 provided on the door body 30.
In this embodiment, the first hinge shaft 41, the second hinge shaft 42, and the third hinge shaft 43 are disposed on the extending portions 402 at the upper and lower ends of the door body 30, and the guide portions 50 and 60 are disposed at the upper and lower ends of the door body 30. It should be noted that, the arrangement of the present embodiment is not limited by the arrangement of the upper and lower ends of the door 30, and the door 30 and the case 10 are connected according to the need.
In the present embodiment, as shown in fig. 2 to 6, the plane on the side (first body side wall) of the case 10 near the hinge plate 40 is defined as the reference plane M 0 Reference plane M 0 One side far away from the inner cavity of the storage chamber is marked as an outer side; in contrast, a reference plane M 0 One side near the inner cavity of the storage chamber is marked as an inner side. As shown in fig. 2, in some embodiments of the present application, in a projection of a plane on which a top wall of the case 10 is located, a line on which a central axis of the first hinge shaft 41 and a central axis of the second hinge shaft 42 are located is perpendicular to the first body sidewall; that is, in the projection of the plane of the top wall of the case 10, the straight line of the central axis of the first hinge shaft 41 and the central axis of the second hinge shaft 42 is parallel to the plane of the pick-and-place opening; so that the positioning of the hinge shaft can be detected, and the processing precision is ensured, thereby ensuring the assembly precision and increasing the fluency of the rotation opening of the door body 30.
In the present embodiment, a trajectory in which the guide portion 50 guides the relative movement of the center axis of the first hinge shaft 41 is denoted as a guide trajectory S, and a trajectory in which the guide portion 60 guides the relative movement of the second hinge shaft 42 is denoted as a guide trajectory K; the centroid of the guide track line K is denoted as guide centroid O. In this embodiment, the guide track line K surrounds its guide centroid O. In this embodiment, the guide track line S is a straight line, and the guide track line K is a ring; that is, during the opening of the door body 30, the guide part 50 guides the first hinge shaft 41 to move, so that the central axis of the first hinge shaft 41 moves straight along the guide trajectory S, and the second hinge shaft 42 and the third hinge shaft 43 are engaged with the guide part 60 to move with respect to the guide trajectory K.
In some embodiments of the present application, the guide track line S extends in a straight line from its end that is closer to the door side wall 32 and the door front wall 31 to a direction away from the door side wall 32 and the door front wall. Wherein, the included angle of the guiding track line S and the door front wall 31 is marked as theta; θ is any one of 20 ° to 45 °. Settable, θ=30°. The above angle setting of θ can control the instantaneous displacement direction of the door 30 during the opening process by the cooperation of the guide portion 50 and the first hinge shaft 41, thereby controlling the lateral displacement of the door 30 with respect to the case 10. During the opening process of the door body 30, the first hinge shaft 41 moves along a straight line with an angle theta relative to the door body 30 and the door front wall 31, so that the displacement of the door body 30 in the direction perpendicular to the door side wall 32 and the direction perpendicular to the door front wall 31 is effectively controlled.
In some embodiments of the application, the guide track line K surrounds the guide track line S. In the projection of the plane of the top wall of the case 10, the guide track line K surrounds the first hinge axis 41, the second hinge axis 42 and the third hinge axis 43.
As one possible arrangement, the guide portion 50 is provided as a guide groove, the guide portion 60 is provided as a guide groove, and the center trajectory line of the guide groove is the guide trajectory line S. The groove wall of the guide groove is annular to define an annular guide track line K. In the projection of the plane of the top wall of the case 10, the groove wall of the guide groove surrounds the guide groove, the first hinge shaft 41, the second hinge shaft 42, and the third hinge shaft 43. The first hinge shaft 41 moves linearly with respect to the guide groove during the opening of the door body 30, and the second hinge shaft 42 and the third hinge shaft 43 move with respect to the guide groove, respectively, so that the door body 30 has a certain displacement in the lateral direction during the opening.
The guide 60 defines a closed loop guide track line in the present application. The guide groove can be an annular closed groove. The annular guide part 60 has high strength, good workability and good machining precision; in addition, the annular arrangement form enables the guide part 60 to have excellent detectability and ensures precision; further, the annular guide portion 60 has a good resistance to deformation, and the accuracy thereof is effectively ensured. The first hinge shaft 41 fixed with the case 10 is matched with the linear guide part 50 in combination with the linear guide part 50, and the second hinge shaft 42 and the third hinge shaft 43 are matched with the guide part 60, so that the movement of the door body 30 can be precisely controlled, and the door body 33 can be displaced by a certain distance in the transverse direction, so that the requirements of various applications can be met; and increases the stability of the movement of the door 30, improving the user experience.
In some embodiments of the present application, the guide groove is a straight groove corresponding to the arrangement in which the guide track line S is a straight line inclined with respect to the door front wall 31, and the guide groove is inclined with respect to the door side wall 32, and extends from one end thereof close to the first side edge W in a direction away from the door front wall 31 and the door side wall 32. Wherein, the included angle between the guide groove and the door front wall 31 is θ, which increases the detectability of the machining precision of the guide portion 50, and facilitates the detection, adjustment and ensuring of precision, so as to improve the precision of motion control of the door body 30.
In some embodiments of the present application, the end of the door body 30 adjacent to the door sidewall 32 is recessed toward the side adjacent to the interior cavity of the door body 30 to form a mounting platform, and the second hinge member (the guide 50 and the guide 60) is disposed on the mounting platform.
As an alternative, as shown in fig. 5-6, the extension 402 of the hinge plate 40 includes a first extension plate 4021 and a second extension plate 4022; one end of the first extension plate 4021 is connected to the connection part 401, and the other end is connected to the second extension plate 4022. The first extension plate 4021 has a first edge adjacent the first body sidewall. The first edge extends obliquely in a direction away from the first body side wall in a direction directed toward the second extending plate 4022 by the connecting portion 401. The second extension panel 4022 has a second edge adjacent to the side of the access opening. The first and second edges are joined to define a relief opening on a side of the extension 402 adjacent the first body side wall. The open end of the relief opening faces the first body sidewall. When the door body 30 is opened, the avoidance opening allows the portion of the door body 30 close to the door side wall 32 to gradually enter the avoidance opening, so that the door body 30 is ensured not to interfere with the extension portion 402 when being opened, and the door body 30 can be opened to a larger angle.
As another alternative, the door body 30 has a door corner 7 adjacent the door sidewall 32; the door corner 7 has a top plate 71 and a side plate 72 forming part of the door side wall 32. The top plate 71, the side plates 72 and the mounting table together define the accommodation space 70. When the door 30 is closed, the extension 402 of the first hinge member is at least partially received in the receiving space 70 to cooperate with the second hinge member. The door corner 7 shields the extension part 402 of the second hinge piece and the first hinge piece when the door body 30 is closed, so that dust fall-in is reduced, and the smoothness of the matching of the hinge components is effectively ensured. The above arrangement of the avoidance opening prevents the door body 30 (the side plate 72 of the door corner 7 or the area of the door front wall 31 near the first side edge W) from interfering with the extension portion 402 when the door body 30 is opened, and effectively ensures that the door body 30 can be opened to a larger angle.
In some embodiments of the present application, the guide 50 is adjacent to the door front wall 31 relative to the plane of the access opening when the door 30 is closed. The first hinge shaft 41, the second hinge shaft 42, and the third hinge shaft 43 are disposed at an end of the extension 402 away from the access opening. The first hinge shaft 41, the second hinge shaft 42, and the third hinge shaft 43 may be disposed on the second extension plate 4022, so that the extension part 402 has enough space to provide an avoidance opening, so as to avoid interference when the door 30 is opened, and further ensure an opening angle of the door 30. On the other hand, the first hinge shaft 41, the second hinge shaft 42, and the third hinge shaft 43 are disposed on the second extension plate 4022 far from the picking and placing port, and apply a force to a position of the door body 30 close to the door front wall 31 when the door body is in the closed state, and in cooperation with the force of the hinge plate 40, the overall supporting effect of the first hinge member on the door body 30 is increased, so that the door body 30 is prevented from being deformed and displaced due to sinking of the door body 30 under the action of gravity.

In combination, the door body 30 is opened from the closed state to G 10 (G 10 In the whole process of more than 90 DEG, the movement of the door body 30 relative to the case body 10 is divided into three stages, and the door body 30 moves outwards, inwards and outwards.

In this embodiment, the door 30 has a tendency to move outwardly during the first stage of opening. Specifically, the first hinge shaft 41 moves a distance away from the door side wall 32 and the door front wall 31 with respect to the guide groove to move the door body 30 outwardly a distance. When the door body 30 is rotated from the closed state to G 2 In the process of (1)The hinge shaft 41 moves away from the door side wall 32 and the door front wall 31 with respect to the guide groove, the second hinge shaft 42 moves away from the door side wall 32 and toward the door front wall 31 with respect to the guide groove, and the third hinge shaft 43 moves away from the door side wall 32 and the door front wall 31 with respect to the guide groove.

Specifically, the door body 30 is formed by G 2 Rotate and open to G 5 The first hinge shaft 41 moves a distance with respect to the guide groove in a direction approaching the door side wall 32 and the door front wall 31 to move the door body 30 inward a distance. In some embodiments of the present application, the second hinge shaft 42 moves away from the door side wall 32 and toward the door front wall 31 with respect to the guide slot while the first hinge shaft 41 moves toward the door side wall 32 and toward the door front wall 31 with respect to the guide slot, and the third hinge shaft 43 moves toward the door side wall 32 and away from the door front wall 31 with respect to the guide slot. The above arrangement makes the door body 30 at the position of G 2 Rotate and open to G 5 Is moved inward during the course of (a). The above arrangement is suitable for the embedded installation and use situations that the refrigerator is placed in a cabinet. When the door body 30 is opened, the door body moves inwards, so that the outward displacement of the first side edge W caused by the pure rotation of the door body 30 can be effectively compensated, and the first side edge W is limited to exceed the reference plane M 0 The distance between the cabinet and the side wall of the refrigerator body is not exceeded, the mutual interference between the door body 30 and the cabinet 100 is effectively avoided when the door body 30 is opened, the limit of the cabinet 100 space on the size of the refrigerator which can be accommodated is further reduced, and the utilization rate of the cabinet 100 space is improved.

For example, a door 30 may be provided which opens from a closed position to G 2 The door body 30 rotates about the first hinge shaft 41. Additionally, the door body 30 is opened from the closed state to G 2 The door 30 also has a tendency to move inwardly during the process. Similarly, the arrangement of the first stage is not limited by the arrangement of the second stage.

In the above arrangement, G 5 Less than 90 deg.. That is, the door body 30 has a tendency to move outwardly during the 90 ° opening; the door body 30 can reduce the shielding of the door body to the taking and placing opening, so that the articles can be taken and placed conveniently, and the transverse width of the drawer can be increased and the space utilization rate of the drawer can be increased on the premise that the drawer placed in the storage chamber can be pulled out. In addition, when the refrigerator is used together with the second stage, when the refrigerator is placed in the embedded installation and use scene of the cabinet, the displacement of the door body 30 which is moved outwards in the earlier stage and is used for avoiding the inward movement of the cabinet can be compensated by the later stage of the door body 30, so that the transverse space of the cabinet is fully utilized, and the shielding of a taking and placing opening due to the inward movement of the earlier stage of the door body 30 is reduced.
It should be noted thatIn some embodiments of the present application, the third stage is independently arranged and is not opened from the closed state to G by the first stage door 30 2 The outward movement of the door 30 is not limited by G of the second stage door 30 2 Rotate and open to G 5 The door 30 is limited to move inwardly during the process.

In the second embodiment, as shown in fig. 50 to 53, the refrigerator includes two oppositely disposed door bodies 30, and the two oppositely disposed door bodies 30 cooperate together to open or close the access opening. One side of any one of the two door bodies 30, which is far away from the door side wall 32 thereof, is provided with a side sealing strip 3; when the two door bodies 30 are closed, the side sealing strip 3 on any one of the two door bodies 30 is in sealing fit with the side sealing strip 3 on the other door body; that is, when the two door bodies 30 are closed, the two side sealing strips 3 are pressed in the gap between the two door bodies 30 to effectively close the space between the two door bodies 30 and the box body, thereby preventing the cool air from overflowing.
In combination with the arrangement of the hinge assembly in the second embodiment, the hinge assembly in the present embodiment has the first stage of movement characteristics (see the first embodiment, in which the door body 30 is opened from the closed state to the G state 2 The door body 30 moves outward during the process of (a) and is not described here. That is, in the second embodiment, the door 30 is opened from the closed state to G 2 In the process, the door body 30 moves outwards firstly, so that one of the two oppositely arranged door bodies 30 can be prevented from driving the other door body 30 to be opened when being opened, and the cold energy loss is effectively reduced; and simultaneously, the shielding of the door body 30 to the taking and placing opening can be effectively reduced.
Example III
As shown in fig. 50-53, as shown in fig. 54, the refrigerator in the third embodiment is also provided with two oppositely disposed door bodies 30, and the two oppositely disposed door bodies 30 cooperate together to open or close the access opening. One side of any one of the two door bodies 30, which is far away from the door side wall 32 thereof, is provided with a side sealing strip 3; when the two door bodies 30 are closed, the side sealing strip 3 on any one of the two door bodies 30 is in sealing fit with the side sealing strip 3 on the other door body; that is, when the two door bodies 30 are closed, the two side sealing strips 3 are pressed in the gap between the two door bodies 30 to effectively close the space between the two door bodies 30 and the box body, thereby preventing the cool air from overflowing. The arrangement is the same as the embodiment.
Unlike the second embodiment, the refrigerator of the third embodiment may be adapted to a case of being embedded in a cabinet.
Specifically, unlike the second embodiment, in combination with the provision of the hinge assembly in the first embodiment, the hinge assembly in the third embodiment has the overall movement characteristics of the first and second stages (see the first embodiment in which the door body 30 is opened from the closed state to the G 2 The door body 30 moves outward during the process; the door body 30 is formed by G 2 Rotate and open to G 5 The door body 30 moves inward during the course of (a); and will not be described in detail herein). In the third embodiment, the door 30 of the hinge assembly moves in a first stage of outward movement and then moves in a second stage of inward movement during the opening process.
Specifically, in the third embodiment, the door 30 is opened from the closed state to the closed state 2 During the process, the door 30 is moved outwardly. The door body 30 is formed by G 2 It has a tendency to move inwardly during continued opening. By the arrangement, on one hand, the door body 30 can move outwards at the initial opening stage so as to avoid driving the other door body 30 to open, and the cold energy loss is reduced; on the other hand, the opened door body 30 can move inwards after the two door bodies 30 are separated, the outward displacement of the first side edge W caused by the pure rotation of the door body 30 can be effectively compensated, and the first side edge W is limited to exceed the reference plane M 0 The distance between the cabinet and the side wall of the refrigerator body is not more than the distance, so that the mutual interference between the door body 30 and the cabinet 100 when the door body is opened is effectively avoidedFurther reducing the limitation of the space of the cabinet 100 on the size of the refrigerator which can be accommodated and improving the utilization rate of the space of the cabinet 100. Furthermore, the door 30 is kept moving inwards in the process of opening to the maximum angle, so that the limit of the cabinet to the maximum angle that the door 30 can be opened can be reduced, and the maximum angle that the door 30 of the refrigerator installed in the cabinet can be opened is larger.
Example IV
As shown in fig. 55 to 63, in the fourth embodiment, the refrigerator includes two oppositely disposed door bodies 30, and the two oppositely disposed door bodies 30 cooperate together to open or close the access opening. When the two door bodies 30 are closed, the overturning beam 9 is arranged on the lining surface of one door body 30, which is close to one side of the other door body 30. The top wall of the storage chamber of the refrigerator is provided with a guide rail 91, and the turnover beam 9 can be in sliding fit with the guide rail 91 so as to realize the switching of different angles of the turnover beam 9 relative to the door body 30. When the two door bodies 30 are closed, the turnover beam 9 seals the gap between the two door bodies 30 and the box body 10, so as to effectively prevent the cool air from overflowing.
Specifically, the turnover beam 9 includes a door turnover beam rear cover, the door turnover beam rear cover is connected to the door body 30 through a first door hinge and a second door hinge, and the door turnover beam rear cover is elastically connected with the two door hinges by torsion springs respectively; wherein the first door hinge is located above the second door hinge. Wherein, the top of lid has set firmly guide block 90 behind the door beam, and guide block 90 cooperatees with the guided way 91 as the rotating member of upset roof beam 9 in order to realize the switching of the different angles of upset roof beam 9 relative to door body 30.
The door hinge and the door rotating beam rear cover are respectively provided with a through hole penetrating through the torsion spring arm, and the torsion springs are used for connecting the upper door hinge and the lower door hinge with the door rotating beam rear cover. The door hinge and the door beam rotating rear cover are connected through a first torsion spring, and the door hinge and the door beam rotating rear cover are connected through a second torsion spring. When the turnover beam 9 rotates around the door hinge, the first torsion spring and the second torsion spring store elastic energy or release the elastic energy, so that the door turnover beam rear cover stably rotates and resets in time.
In the opened state of the door body 30, the turnover beam 9 is tightly attached to the door hinge fixed to one side of the inner liner of the door body 30 due to torsion forces (first torsion spring and second torsion spring) of torsion springs.
As shown in fig. 61-63, when the door 30 is closed from the open state, an external force is applied to the door 30, the door 30 is gradually closed under the action of the external force, and the door 30 is closed to an angle G S When the guide block 90 at the top of the turnover beam 9 contacts with the guide rail 91.
At the door 30 is closed to the angle G S When external force is continuously applied, the door body 30 moves continuously along the closing direction, the guide block 90 at the topmost end of the turnover beam 9 enters the guide rail 91, and the guide block 90 interacts with the guide rail 91. During this closing process, since the guide block 90 starts to turn under the pressure of the guide rail 91, the torsion spring is compressed in the radial direction, when the turn beam 9 turns over G F And the critical value of the torsion spring is reached. The torsion spring begins to stretch to release torsion force of the torsion spring so as to enable the turnover beam 9 to quickly turn over in place; until the door body 30 is closed, at which point the torsion of the torsion spring is released and reaches a relaxed state again. After the door body 30 is closed, the turnover beam 9 contacts with a seal arranged on the door body 30, so that the cold air is effectively prevented from overflowing between two opposite-opening type butt joints. If the turnover beam 9 is turned to G F External force is removed before, and the torsion spring is twisted to reach the critical value of the torsion spring, so that the guide block 90 at the top of the turnover beam cannot effectively complete the turnover after entering the guide rail 91 on the box body and is blocked, and the turnover beam cannot automatically complete the turnover, so that the door body 30 with the turnover beam cannot be closed in place, and the low-temperature storage of the refrigerator is invalid.
In the fourth embodiment, the first hinge member is located at a first mating portion of one end of the first hinge member, which is far away from the first body side wall, and a second mating portion is disposed at an end of the door body 30, which is close to the first hinge member, and the second mating portion is used for mating with the first mating portion to lock and unlock the door body 30 and the box body 10. As an alternative, the second mating portion is located on a side of the second hinge member remote from the door sidewall 32.
When the door body 30 is closed in an open state, an external force is firstly applied to the door body 30, and the door body 30 is gradually closed under the action of the external force; as the door body 30 is rotated to be closed, the free end of the second fitting portion gradually approaches the first fitting portion.
When the door 30 is closed to the angle G B0 In the time-course of which the first and second contact surfaces,the second matching part is abutted with the first matching part; then under the action of external force, the door body 30 continues to be closed, the first matching part interacts with the second matching part, the second matching part is elastically deformed, under the combined action of the external force and the acting force of the first matching part, the second matching part and the first matching part gradually approach each other, and the elastic deformation of the second matching part gradually increases.
When the door 30 is closed to the angle G B1 When the second fitting portion elastically deforms, the maximum deformation amount during the closing of the door body 30 is reached.
When the door 30 is closed to G B1 And then continues to move along the closing direction, the elastic energy stored by the earlier deformation of the second matching part is released, and the second matching part is restored to a loose state under the combined action of the elastic energy and the acting force of the first matching part, and the door body 30 is quickly and automatically closed in place; until the door body 30 is closed, the second matching part is locked with the first matching part, so that the door body 30 and the box body 10 are locked. Above, G B0 ＞G B1 . As a settable way, G B0 Setting the value to be any one of 15-20 degrees and G B1 Is set to any one of 3 DEG to 8 deg. In summary, the door 30 is closed to G B1 Thereafter, the door body 30 is automatically closed by the interaction of the first and second mating portions.
It should be noted that, in the closing process of the door 30, the external force continuously acts on the door 30 to close to G B1 After the door body 30 is rotated and closed until the elastic deformation of the second mating portion is maximum, the external force is removed, and the door body 30 can automatically complete the overturning. And when the door body 30 is closed to G B1 After the external force is removed, the door body 30 has an inertial force, and the inertial force also has the characteristic of keeping the door body 30 in the original closed movement trend.
In summary, the door 30 is formed by the angle G B0 Closing to angle G B1 In the process of (2), under the combined action of the external force and the first matching part, the second matching part is elastically deformed.
When the door body 30 is closed to G B1 When the second fitting portion is elastically deformed, the maximum deformation amount of the door body 30 during closing is reached.
At the door body 30From G B1 In the process of closing, the external force is removed, the elastic force of the second matching part is released, and the door body 30 is quickly and automatically closed.
That is, in the fourth embodiment, the door body 30 is formed by G in the configuration of the first engaging portion and the second engaging portion B1 The door 30 has an automatic closing feature during the process to the closed state.
In combination with the arrangement of the hinge assembly in the second embodiment, the hinge assembly in the present embodiment has the first stage of movement characteristics (see the second embodiment in which the door body is opened from the closed state to Q 2 And are not described in detail herein). That is, in the fourth embodiment, the door 30 is opened from the closed state to G 2 The door body 30 moves outward during the course of the process. Correspondingly, the door body 30 is formed by G 2 The door 30 has a tendency to move inwardly during the process to the closed condition.
As a settable way, G B1 ＞G 2 . That is, the door 30 is automatically closed (G B1 During continued closing) has a tendency to move inwardly; the door 30 moves inwardly to apply an inward force to the invert beam 9 which urges the invert beam to invert. Since in the present embodiment, the door 30 is formed by G B1 In the process of continuing to close, the door body 30 has the characteristic of automatic closing, and the door body 30 keeps moving inwards, so that inward acting force applied to the turnover beam 9 by the inward movement of the door body 30 always exists, the turnover beam 9 can be ensured to turn to the position, and the door body 30 is closed in place.
In some embodiments of the present application, referring to fig. 60 to 63, the door body 30 includes a mounting block mounted on the door body 30 at a position opposite to the hinge plate 40, and the guide portion 60 and the second engagement portion are formed on the mounting block. The first mating portion is formed on a side of the extension 402 of the hinge plate 40 remote from the door sidewall 32.
With particular reference to fig. 60-63, the door body 30 has a door end cap 38. In this embodiment, an installation block provided at the lower end of the door body 30 will be described as an example. As shown in fig. 60 to 63, the mounting block is formed with a guide groove. The guide groove comprises a groove bottom and a circumferential groove wall surrounding the edge of the groove bottom; wherein, the tank bottom of the guiding groove is provided with a guiding groove, and the circumferential groove wall of the guiding groove defines a guiding track line K. The door body 30 includes a door end cover 38, and an accommodating groove 37 is formed in the door end cover 38, and the accommodating groove 37 is used for fixing the mounting block. As an embodiment, the mounting block is placed in the receiving groove 37, and then the mounting block is fastened to the door body 30 by the first fixing member. Specifically, the first fixing member may be provided as a screw or the like.
As an embodiment, the mounting block includes a plate body 81, and the plate body 81 is disposed around the outer circumferential side wall of the guide groove. In this embodiment, the first fixing member connecting the mounting block and the accommodation groove 37 fixedly connects the plate body 81 with the door body 30. A plurality of first fixing members may be provided and distributed around the guide groove.
As an arrangement, a first accommodating portion recessed toward the inner cavity of the door body 30 is formed on one side of the bottom wall of the accommodating groove 37 close to the door side wall 32, the guide groove is at least partially accommodated in the first accommodating portion, and the bottom of the guide groove is matched with the inner wall of the first accommodating portion; the plate 81 cooperates with the bottom wall of the receiving slot 37 to effectively define the position of the guide slot.
As an alternative, a second receiving portion recessed toward the inner cavity of the door body 30 is formed on the bottom wall of the cavity of the first receiving portion. The guide groove is arranged in the second accommodating part and matched with the inner wall of the second accommodating part so as to limit the guide groove.
In some embodiments of the application, the second mating portion on the mounting block is configured as a locking structure, and in particular, the second mating portion includes a latch hook 82 provided on a side of the plate 81 remote from the door sidewall 32. The latch hook 82 extends to a side away from the door side wall 32 and is formed by bending to a side close to the door rear wall 33 and the door side wall 32, an opening of the latch hook 82 faces the plate 81 (an opening of the latch hook 82 faces the door side wall 32), and a free end of the latch hook 82 is located at a side thereof close to the door rear wall 33.
The first engaging portion provided on the hinge plate 40 at a side away from the first body sidewall is provided as a stopper portion 403, and a hooking gap 404 is formed at a side of the stopper portion 403 near the case 10. When the door body 30 is in a closed state, the free end of the lock hook 82 is accommodated in the hooking gap 404, the stop part 403 is positioned in the lock hook 82, and the lock hook 82 on the door body 30 hooks the stop part 403 on the hinge plate 40, so that the door body 30 is locked, and the influence on the refrigerating and freezing effects of the refrigerator due to the untight closing of the door body 30 is avoided; when the door body 30 is opened, the latch hook 82 is forced to deform to overcome the blocking of the stop portion 403, and thus, is separated from the stop portion 403.
The latch hook 82 may include a root 83 and a hooking portion 84. The root portion 83 is connected to the plate 81, and the hooking portion 84 is connected to the root portion 83 and bent toward the door rear wall 33 and the door side wall 32. The screw penetrates through the root connection portion 83 and is connected with the door body 30 to strengthen the connection strength of the root connection portion 83 and the door body 30, so that the latch hook 82 only deforms at the hooking portion 84 when being separated from the stop portion 403.
The free ends of the hooking portion 84 and the stopping portion 403 are arc-shaped, which is beneficial for the hooking portion 84 to smoothly hook the stopping portion 403 along an arc or separate from the stopping portion 403.
As shown in fig. 61 to 63, when the door body 30 is closed from the open state, the door body 30 is gradually closed by an external force; as the door body 30 is rotated to be closed, the free end of the hooking portion 84 gradually approaches the stop portion 403. As shown in fig. 62, when the door 30 is closed to G B0 When the hooking portion 84 abuts against the stopper portion 403; then, the door 10 continues to be closed under the action of the external force, the stop portion 403 interacts with the hooking portion 84, the hooking portion 84 is elastically deformed, and under the combined action of the external force and the acting force of the stop portion 403, the movable hooking portion 82 gradually enters the hooking gap 404 (i.e., the stop portion 403 enters the hooking portion 84). As shown in fig. 63, when the door 30 is closed to G B1 When the door body 30 is closed, the elastic deformation amount of the hooking portion 84 reaches the maximum deformation amount. When the door 30 is closed to G B1 After that, the elastic energy stored in the deformation of the hooking portion 82 in the earlier stage is gradually released, and under the combined action of the acting force of the stopping portion 403, the hooking portion 82 is restored to a loose state, and the hooking portion 82 is driven to further enter the hooking gap 404, so that the door body 30 is quickly and automatically closed in place until the door body 30 is closed, and the lock hook 82 is locked with the hinge plate 40, so that the door body 30 is locked with the box body 10. I.e. the door 30 is closed to G B1 The door 30 then has an automatic closing feature.

That is, the door side wall 32 extends from inside to outside and the door rear wall 33 extends from rear to front in a direction from the second side edge N toward the first side edge W with respect to the case 10.
When the door 30 is opened to 90 °, the door 30 has a first direction displacement parallel to the door rear wall 33 and directed to one side of the door side wall 32 with the case 10 as a reference and the case 10 as a referenceSecond direction displacement parallel to door side wall 32 and directed to door front wall 31 side +.>I.e. firstDirection shift->Toward the rear side of the case 10, the second direction is displaced +>Pointing to the outside of the case 10.

(2) As shown in fig. 39, when the door 30 is opened by 90 ° rotation to Q 8 (Q 8 During the 90 deg. rotation of the door 30 counter-clockwise relative to the cabinet 10, the door side wall 32 also rotates counter-clockwise during this phase of opening. In the plane of the top wall of the case 10, the door side wall 32 extends outwardly and rearwardly in a direction from the second side edge N to the first side edge W; the door rear wall 33 extends outwardly and forwardly in a direction from the door side wall 32 toward the opposite end of the door body 30 from the door side wall 32.

In combination, door 30 is opened from a closed condition to Q 8 In the whole process, the door 30 moves in two stages with respect to the case 10, and the door 30 has a tendency to move inward and then outward.
In the present embodiment, the angles of the range of 0 to 90 °, 90 ° to G are only used in the same way as the first embodiment max ＝Q 8 Some angles within the range are used as representative to illustrate the overall movement tendency, but they can represent the movement tendency within the corresponding range, and it can be illustrated that the hinge assembly having the above track features of the present invention can provide a first-in-second-out movement tendency (inward-outward) during opening of the door body 30.
In the sixth embodiment, the first stage of opening the door 30 has a tendency to move inward. Specifically, as a settable manner, the door body 30 is rotated to be opened to Q from the closed state 3 In the process of (1)The hinge shaft 41 moves away from the door side wall 32 and toward the door front wall 31 with respect to the guide groove, the second hinge shaft 42 moves toward the door front wall 31 with respect to the guide groove, and the third hinge shaft 43 moves away from the door front wall 31 with respect to the guide groove. The arrangement of the inward movement of the door body 30 in the opening process is suitable for the situation that the refrigerator is placed in the embedded installation of the cabinet, and on one hand, the arrangement can be arranged at the earlier stage of opening the door body 30 so that the door body 30 moves inwards, the outward displacement of the first side edge W caused by the pure rotation of the door body 30 can be effectively compensated, and the first side edge W is limited to exceed the reference plane M 0 The distance between the cabinet and the side wall of the refrigerator body is not exceeded, the mutual interference between the door body 30 and the cabinet 100 is effectively avoided when the door body 30 is opened, the limit of the cabinet 100 space on the size of the refrigerator which can be accommodated is further reduced, and the utilization rate of the cabinet 100 space is improved. On the other hand, the sixth door 30 of the present embodiment moves inward from the process of opening to the maximum angle, so that the limit of the cabinet to the maximum angle that the door 30 can open can be reduced, and the maximum angle that the door 30 of the refrigerator installed in the cabinet can open can be made larger.
As a settable way, the door body 30 is rotated to be opened to Q from the closed state 3 The third hinge shaft 43 moves relative to the guide slot in a direction away from the door front wall 31 and toward the door side wall 32. As another alternative, the third hinge shaft 43 moves away from the door front wall 31 and moves away from the door side wall 32 and then moves toward the door side wall 32 simultaneously with the guide groove.

Specifically, as one ofIn a configurable manner, gate 30 is formed from Q 3 Open to Q 8 The first hinge shaft 41 moves away from the door side wall 32 and toward the door front wall 31 with respect to the guide groove, the second hinge shaft 42 moves away from the door side wall 32 and toward the door front wall 31 with respect to the guide groove, and the third hinge shaft 43 moves toward the door side wall 32 with respect to the guide groove. As an alternative, during the second phase of opening, the third hinge shaft 43 moves relative to the guide slot in a direction away from the door front wall 31 and then in a direction towards the door front wall 31. In the above arrangement, Q 3 Less than 90 deg.. That is, the door body 30 has a tendency to move outwardly during the 90 ° opening; the door body 30 can reduce the shielding of the door body to the taking and placing opening, so that the articles can be taken and placed conveniently, and the transverse width of the drawer can be increased and the space utilization rate of the drawer can be increased on the premise that the drawer placed in the storage chamber can be pulled out. In addition, when the refrigerator is used together in cooperation with the first stage in the embodiment, when the refrigerator is placed in the embedded installation and use scene of the cabinet, the displacement of the door body 30, which is moved inwards for avoiding the cabinet in the earlier stage, can be compensated by the outward movement of the door body 30 in the later stage, so that the transverse space of the cabinet is fully utilized, and the shielding of a taking and placing opening due to the inward movement of the door body 30 in the earlier stage is reduced.
It should be noted that, in the sixth embodiment, the first stage and the second stage may be separately set, which is not limited by the movement condition of the other stage; it can also go through the first stage and then go through the second stage.
