Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application, and fig. 2 is a sectional view of the refrigerator shown in fig. 1. The embodiment of the application provides a refrigerator, which can comprise a refrigerator body 10, a door body 20 and a hinge plate 30. The cabinet 10 is provided with a storage compartment such as a freezing compartment, a refrigerating compartment, or a wide temperature-variable compartment. Of course, in some alternative embodiments, the storage compartment may also be a thawing compartment or a sterilization compartment with a thawing function, which is not limited in the examples of the present application. The door 20 is used to open or close the storage compartment of the cabinet 10. The door 20 may be hinged to the cabinet 10 by a hinge plate 30. Specifically, hinge plates 30 may be disposed at an upper portion and a lower portion of the box 10, and the hinge plates at the upper portion of the box 10 and the hinge plates at the lower portion of the box 10 cooperate with the door 20 to allow the door 20 to smoothly rotate.

Wherein, the front end of storing room is formed with the opening or gets and put the mouth to place food to storing indoor or by the indoor food of taking out of storing room. The box body 10 includes an opening end surface 11 surrounding an opening of the storage compartment.

It will be appreciated that the enclosure 10 includes oppositely disposed first and second side walls 12, 13 (i.e., right and left side walls of the enclosure 10). The hinge plate 30 is provided on the housing 10 adjacent to the first sidewall 12. Alternatively, the hinge plate 30 is provided on the housing 10 adjacent to the second sidewall 13. Of course, for a double door refrigerator, hinge plates 30 are provided adjacent to both the first side wall 12 and the second side wall 13.

Door 20 includes a door rear wall surface 211, a door front wall surface 212, and a door side wall surface 213 adjacent to hinge plate 30, it being understood that door rear wall surface 211 faces the opening end surface 11 of cabinet 10 when door 20 is in a closed state. Door rear wall surface 211 is provided opposite to door front wall surface 212, and door side wall surface 213 is connected to door rear wall surface 211 and door front wall surface 212. It can be understood that, when the hinge plate 30 is located at the right side of the box body 10, the right side surface of the door body 20 is the door body side wall surface 213; when hinge plate 30 is positioned on the left side of casing 10, the left side surface of door 20 is door side wall surface 213. The intersection of the door body front wall surface 212 and the door body side wall surface 213 of the door body 20 forms a first side edge 214, or the intersection of the door body front wall surface 212 and the door body side wall surface 213 forms a corner portion of the door body 20. It should be noted that when the door body front wall surface 212 and the door body side wall surface 213 are both flat surfaces, an intersection line of the two flat surfaces is a theoretical first side edge 214, and when the door body front wall surface 212 and the door body side wall surface 213 are in circular transition during specific processing, a curved surface is formed at this time based on that the intersection of the door body front wall surface 212 and the door body side wall surface 213 is in circular transition, and a vertical line extending along the length direction of the door body 20 and located in the middle of the curved surface on the curved surface can represent the first side edge 214.

It should be noted that, in the related art, when the door body rotates, the corner portion (or the first side edge) of the door body may exceed the side wall of the refrigerator by an excessive distance, and at this time, if the refrigerator is closer to the side wall of the refrigerator or the cabinet, the corner portion of the door body may touch the side wall of the refrigerator or the cabinet, which directly affects the use of the user.

Based on this, please refer to fig. 3 to 9, fig. 3 is an exploded view of the door and the hinge plate in fig. 1, fig. 4 is a schematic structural view of the hinge plate shown in fig. 3, fig. 5 is a schematic structural view of a first sliding chute and a second sliding chute which are matched with a boss and a shaft body, fig. 6 is a schematic structural view of the boss, the shaft body and a door body rotating shaft plate in fig. 3, fig. 7 is a partially enlarged view of the structure shown in fig. 2 at a hinge joint, fig. 8 is a schematic structural view of the structure shown in fig. 7 when the door body is opened to a first preset angle, and fig. 9 is a schematic structural view of the structure shown in fig. 7 when the door body is opened to a second preset angle. The hinge plate 30 is connected to the housing 10, and the hinge plate 30 is provided with a first slide groove 32 and a second slide groove 33. The door 20 can rotate relative to the cabinet 10, the door 20 is provided with a boss 22 and a shaft body 23, the shaft body 23 includes a first end 231 and a second end 232 which are oppositely arranged along a radial direction of the shaft body 23, it can be understood that the shaft body 23 further includes a connecting portion 233, and the first end 231 and the second end 232 are respectively connected to two ends of the connecting portion 233. When the door 20 is in the closed state, the first end 231 is located between the cabinet 10 and the second end 232, specifically, the first end 231 is located between the opening end face 11 of the refrigerator and the second end 232, or the first end 231 is closer to the opening end face 11 of the refrigerator than the second end 232. The boss 22 is connected to the first end 231 and protrudes from the first end 231 toward the side where the first sliding chute 32 is located. It will be appreciated that the boss 22 is closer to the open end face 11 of the refrigerator than the second end 232 (as shown in figure 7). Wherein the boss 22 is engaged with the first sliding slot 32, and the second end 232 is engaged with the second sliding slot 33. Or the boss 22 is inserted into the first sliding slot 32, and the second end portion 232 is inserted into the second sliding slot 33.

In the process that the door body 20 rotates from the closed state to the first preset angle a, the door body 20 can rotate with the second end portion 232 as a rotation axis, and the boss 22 can slide relative to the first chute 32. In the process that the door body 20 is opened from the first preset angle a to the second preset angle b, the door body 20 can rotate with the boss 22 as a rotation axis, and the second end 232 can slide relative to the second chute 33. It will be appreciated that the first preset angle a is greater than the second preset angle b. Through the matching of the boss 22 and the first chute 32 and the matching of the second end 232 and the second chute 33, after the door body 20 rotates to a certain angle in a fixed axis manner, another axis can be replaced to perform fixed axis rotation movement, that is, the door body 20 performs two-stage diameter-variable movement in the rotation process, and because the first end 231 is located between the refrigerator body 10 and the second end 232, and the boss 22 is connected to the first end 231, in the process that the door body 20 rotates from the closed state to the second preset angle b, the rotation radius of the corner portion of the door body 20 rotating with the second end 232 as the axis is smaller than the rotation radius of the corner portion of the door body 20 rotating with the boss 22 as the axis, so that the rotation center of the door body 20 starts to be adjusted when the corner portion of the door body 20 exceeds the side wall surface of the refrigerator body 10 by a small distance (at this time, the door body 20 rotates with the boss 22 as the rotation axis), so as to avoid the cabinet or the wall on the side of the refrigerator, and enable the door body 20 to smoothly move when being opened. In addition, since the boss 22 is disposed at the first end 231 of the shaft body 23, the structural strength between the boss 22 and the shaft body 23 is enhanced to some extent, and the strength of the structure is better than that of a dual-shaft structure disposed at an interval.

It can be understood that the upper end portion and the lower end portion of the refrigerator are provided with the hinge plates 30, and the upper end and the lower end of the door body 20 are provided with the bosses 22 and the shaft bodies 23 corresponding to the positions of the hinge plates 30. The bosses 22 at the upper and lower ends of the door 20 are corresponding to each other in the vertical direction, and the shaft bodies 23 at the upper and lower ends of the door 20 are corresponding to each other in the vertical direction, so that the movement of the upper and lower ends of the door 20 is kept consistent, and the door 20 is opened or closed more smoothly.

It will also be appreciated that the hinge plate 30 may be fixed to the cabinet 10 of the refrigerator by means of a screw connection. The first slide groove 32 and the second slide groove 33 are provided to the hinge plate 30.

The refrigerator may further include a door body rotating shaft plate 40, the door body rotating shaft plate 40 is detachably disposed on the door body 20, and the boss 22 and the shaft body 23 are disposed on the door body rotating shaft plate 40. For example, the boss 22 and the shaft body 23 may be integrally formed with the door body pivot plate 40. Alternatively, the boss 22 and the shaft body 23 may be integrally formed and then assembled to the door body pivot plate 40. The door body rotating shaft plate 40 can be fixed on the door body 20 in a screw connection mode, so that the door body rotating shaft plate 40 can be conveniently assembled and disassembled.

In order to more clearly illustrate the matching connection relationship between the boss 22 and the first sliding slot 32, and the matching connection relationship between the second end 232 of the shaft body 23 and the second sliding slot 33, the specific structure of the boss 22, the first sliding slot 32, the shaft body 23 and the second sliding slot 33 will be described in detail below with reference to the drawings.

Referring to fig. 4 to 9, the first sliding groove 32 is communicated with the second sliding groove 33, the depth of the first sliding groove 32 is greater than that of the second sliding groove 33, the boss 22 extends to the first sliding groove 32, and the second end 232 extends to the second sliding groove 33. In this manner, the positions of the first and

second chutes

32 and 33 can be made relatively more compact.

The boss 22 comprises a boss bottom surface 221 and a boss side surface 222, the boss side surface 222 is connected to the boss bottom surface 221 in a surrounding mode, the first chute 32 comprises a first positioning section 321 and a first track section 322 which are communicated with each other, the first track section 322 comprises a first chute bottom wall in contact with the boss bottom surface 221 of the boss 22 and a first chute side wall in contact with the boss side surface 222, in the process that the door body 20 rotates to a first preset angle a from the closed state, the door body 20 can rotate by taking the second end portion 232 as a rotation axis, and at the moment, the boss 22 can slide relative to the first track section 322 and slide to the first positioning section 321. In the process that the door body 20 is opened from the first preset angle a to the second preset angle b, the boss 22 can rotate relative to the first positioning segment 321, that is, at this time, the door body 20 can rotate with the boss 22 as a rotation axis, and the second end 232 can slide relative to the second chute 33.

It is understood that the second end 232 includes an end bottom surface 2321 and an end side surface 2322, the end side surface 2322 is connected to the end bottom surface 2321 in a surrounding manner, the second sliding slot 33 includes a second positioning segment 331 and a second track segment 332 which are communicated with each other, and the second track segment 332 includes a second slot bottom wall contacting the end bottom surface 2321 of the second end 232 and a second slot side wall 3321 contacting the end side surface 2322. When the door body 20 is in the closed state, the second end 232 is located at the second positioning section 331, and in the process that the door body 20 rotates to the first preset angle a from the closed state, the second end 232 can rotate relative to the second positioning section 331, and at this time, the boss 22 can slide relative to the first track section 322 and slide to the first positioning section 321. In the process that the door body 20 is opened from the first preset angle a to the second preset angle b, the boss 22 can rotate relative to the first positioning segment 321, that is, at this time, the door body 20 can rotate with the boss 22 as a rotation axis, and the second end 232 can slide relative to the second track segment 332.

It can be further understood that, as shown in fig. 6, the connection portion 233 includes a connection portion bottom surface 2331 and a connection portion side surface 2332, and the connection portion side surface 2332 is connected to the connection portion bottom surface 2331 in a surrounding manner and is connected to the end portion side surface 2322 of the second end portion 232, wherein the connection portion bottom surface 2331 is coplanar with the end portion bottom surface 2321, and both the connection portion bottom surface 2331 and the end portion bottom surface 2321 are in contact with the second groove bottom wall of the second track section 332, so that the contact area between the shaft body 23 and the second groove bottom wall of the second track section 332 can be increased, and the door body can be more stable and smooth in the rotation process.

When the door body 20 rotates from the closed state to the first preset angle a, the second end 232 relatively rotates in the second positioning section 331, the door body 20 can rotate with the second end 232 as a rotation axis, the boss 22 slides to the first positioning section 321 relative to the first track section 322, at this time, the door body 20 continues to rotate, the boss 22 relatively rotates in the first positioning section 321 in the process of opening the door body 20 from the first preset angle a to the second preset angle b, the door body 20 can rotate with the boss 22 as a rotation axis, and the second end 232 and the connecting portion 233 slide relative to the second track section 332. That is to say, when the door 20 rotates to the first preset angle a from the closed state, the door 20 rotates with the second end 232 as the rotating shaft, and when the door 20 rotates to the second preset angle b from the first preset angle a, the door 20 rotates with the boss 22 as the rotating shaft, and the door 20 performs two-section variable-diameter motion in the rotating process, so that the corner of the door 20 starts to adjust the rotating center of the door 20 when exceeding the side wall of the refrigerator body 10 by a small distance, so as to avoid the cabinet or the wall on the side of the refrigerator, and make the door 20 move smoothly when being opened.

As shown in fig. 5, the first track section 322 is an arc-shaped groove, the second groove sidewall 3321 of the second track section 332 is an arc-shaped sidewall, and the arc-shaped first track section 322 and the arc-shaped second groove sidewall 3321 play a guiding role. The first positioning segment 321 is located at the center of the second groove sidewall 3321 of the second track segment 332, and the second positioning segment 331 is located at the center of the first track segment 322.

It should be understood that, referring to fig. 10 together, fig. 10 is an enlarged view of a point a in fig. 7. When the door 20 rotates from the closed state to the first predetermined angle a, that is, when the door 20 rotates around the second end 232, it is necessary to ensure that the first side edge 214 of the door 20 (or the corner of the door 20) does not collide with the wall or the cabinet wall. Based on this, the distance between the center of the second end 232 and the door body front wall surface 212 is set to L ₁ The distance between the center of the second end 232 and the door body side wall surface 213 is L ₂ The distance between the door body side wall 213 and the wall or the cabinet wall is denoted as L ₃ It can also be understood that when the door 20 is in the closed state, the distance between the groove center of the second positioning segment 331 and the door front wall 212 is denoted as L ₁ The distance between the groove center of the second positioning segment 331 and the door body side wall surface 213 is denoted as L ₂ Wherein, in the step (A),

therefore, when the door body 20 rotates around the second end 232, the arc-shaped track of the first side edge 214 does not interfere with the wall or the cabinet wall.

For example, in the case of a built-in refrigerator, the distance between the side plate of the built-in cabinet and the side wall of the refrigerator is small, and is generally 2 mm to 4 mm. Based on this, in order to improve the adaptability without greatly modifying the structure of the door 20 of the existing refrigerator, the distance L between the center of the second end 232 and the door front wall 212 can be set ₁ A distance L between the center of the second end 232 and the door body side wall surface 213 is set between 8.5 mm and 10.5 mm ₂ Set between 14 mm and 17 mm. Or, the distance L between the groove center of the second positioning segment 331 and the door front wall 212 when the door 20 is in the closed state ₁ The distance L between the groove center of the second positioning section 331 and the door body side wall surface 213 is set between 8.5 mm and 10.5 mm ₂ Set between 14 mm and 17 mm. Thus, under the condition that the structure of the door body 20 of the existing refrigerator is not greatly changed, such as the condition that the thickness of the door body 20 is not changed, when the door body 20 rotates by taking the second end 232 as a rotating shaft, the arc-shaped track moved by the first side edge 214 can not interfere with a wall or a cabinet wall.

For example, the distance L between the center of the second end 232 and the door body front wall 212 may be set ₁ The distance L between the center of the second end 232 and the door body side wall surface 213 is set to 9 mm ₂ Set at 16 mm. Alternatively, the groove center of the second positioning section 331 may be located in front of the door bodyDistance L between walls 212 ₁ The distance L between the groove center of the second positioning section 331 and the door body side wall surface 213 is set to 9 mm ₂ With a 16 mm setting, since a fillet with a radius of 1 mm is generally processed at the first side edge 214 (at the corner of the door body 20), the size of the first side edge 214 exceeding the side wall of the box 10 during the rotation of the door body 20 can be finally enabled to be not more than 2 mm.

It can be understood that after the door body 20 moves to the first preset angle a by using the second end 232 as a rotating shaft, the door body 20 moves to the second preset angle b by using the boss 22 as a rotating shaft, so as to implement two-stage variable diameter movement of the door body 20. The center distance between the boss 22 and the second end 232 is set between 9.5 mm and 12.5 mm, and the second end 232 is farther from the door body side wall surface 213 than the boss 22. Thus, when the door body 20 is converted to move by taking the boss 22 as a rotating shaft, the arrangement position of the boss 22 can prevent the arc-shaped track of the first side edge 214 from interfering with a wall or a cabinet wall in the rotating process of the door body 20. And when the door body 20 moves to the second preset angle b, the door body 20 does not obstruct the drawer in the storage compartment from being pulled out.

As shown in fig. 7, an angle d between an extension line of a connecting line between the center of the boss 22 and the center of the second end 232 and the door body side wall surface 213 is in a range of 15 degrees to 25 degrees, so that the door body 20 performs two-stage diameter-changing movement more smoothly.

For ease of understanding, the following description will be made with reference to specific rotational angles of the door body 20.

For example, the first preset angle a may be 45 degrees, and the second preset angle b may be 90 degrees, in other embodiments, the first preset angle a may be other angles such as 30 degrees or 35 degrees, and the second preset angle b may be other angles such as 80 degrees or 85 degrees, which is not limited herein in this embodiment of the application.

In the embodiment of the present application, the first predetermined angle a is 45 degrees, and the second predetermined angle b is 90 degrees. When the door body 20 is opened to an angle of 45 degrees from the closed state, the second end portion 232 relatively rotates in the second positioning section 331, the door body 20 can rotate with the second end portion 232 as a rotation axis, the boss 22 slides to the first positioning section 321 relative to the first trajectory section 322, at this time, the door body 20 continues to rotate, and when the door body 20 is opened to an angle of 90 degrees from the angle of 45 degrees, the boss 22 relatively rotates in the first positioning section 321, at this time, the door body 20 can rotate with the boss 22 as a rotation axis, and the second end portion 232 slides relative to the second trajectory section 332.

In some embodiments, the door 20 can be opened to a position greater than a second preset angle b (such as 90 degrees), and at this time, the refrigerator can be placed in a position with a larger accommodating space, and it can be understood that when the space is larger, the problem that the door 20 collides with the surrounding wall surface when the door 20 rotates to a position greater than 90 degrees does not need to be considered at this time.

For example, referring to fig. 11 in combination with fig. 5 and 6, fig. 11 is a schematic structural view of the door body in the structure shown in fig. 7 when the door body is opened to a third preset angle. The door 20 may be opened to a third preset angle c, which is greater than the second preset angle b, such as 120 degrees. The second sliding chute 33 may further include a limiting section 333 communicated with the second track section 332, the limiting section 333 is located at one end of the second track section 332 far away from the second positioning section 331, and in a process that the door body 20 is opened from the second preset angle b to the third preset angle c, the door body 20 can rotate with the boss 22 as a rotation axis, and the second end 232 can slide relative to the second track section 332 to abut against a groove wall of the limiting section 333. Therefore, the door body 20 can be limited to continue rotating by taking the boss 22 as a rotating shaft through the limiting effect of the limiting section 333.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
