Description

Technical Field

[0001] The present disclosure relates to the field of household appliances, and particularly to a refrigerator. Background Art

[0002] The door body is one of the important components in the refrigerator system. It is mainly used to open or close the access opening to achieve functions such as wind blocking and storing food ingredients in the closed state. At the same time, touch and display devices can also be set.

[0003] Normally, the door body and the refrigerator are fixed together by means of a hinge, and the door body can make a circular rotational movement around the hinge axis. In some cases, the refrigerator is placed in a corner, and a certain distance needs to be maintained between the refrigerator and the wall to ensure that the door body can be opened and its angle is greater than 90°. To save the space of the house, built-in refrigerators are one of the main development trends in the future. However, for built-in refrigerators, if a traditional hinge mechanism is used, it will not be able to open the refrigerator door body well. Summary of the Invention

[0004] Some embodiments of the present disclosure propose a refrigerator that can reduce the problem of the installation space restricting the opening of the door body.

[0005] The present disclosure provides a refrigerator, including:

[0006] A box body, provided with an access opening; and

[0007] A door body, rotatably connected to the box body around a preset axis to open or close the access opening; the door body includes a first side wall and a second side wall arranged opposite to each other, the first side wall is farther from the box body than the second side wall, the distance between the preset axis and the first side wall is D, the thickness of the door body is B, and D = (1 / 4 - 1 / 3)*B.

[0008] In some embodiments, the door body further includes a third side wall, the third side wall is connected between the first side wall and the second side wall, and is located on the side close to the preset axis, the distance between the preset axis and the third side wall is E, and D ≤ E ≤ 1.3D.

[0009] In some embodiments, the door body further includes a third side wall, the third side wall is connected between the first side wall and the second side wall, and is located on the side close to the preset axis, and a fillet is provided between the first side wall and the third side wall.

[0010] In some embodiments, the radius of the fillet is R, and R = (1 / 6 - 1 / 5)*B.

[0011] In some embodiments, there is a gap A between the box body and the door body, and D ≤ A ≤ 1.3D.

[0012] In some embodiments, the door body further includes a third side wall, which is connected between the first side wall and the second side wall and is located on one side close to the preset axis. The third side wall intersects with the first side wall to form a first edge line, and the first movement trajectory of the first edge line during the rotation of the door body is located inside the extension surface of the side surface of the box body.

[0013] In some embodiments, the distance between the first movement trajectory and the extension surface first decreases and then increases as the opening angle of the door body increases; and / or the distance between the first movement trajectory and the box body decreases as the opening angle of the door body increases.

[0014] In some embodiments, the first movement trajectory is arc-shaped and tangent to the extension surface. The tangent point is the first point of the first movement trajectory. The first point is located on the first edge line when the door body is opened to a preset angle, and the preset angle is less than 90°.

[0015] In some embodiments, the refrigerator further includes: at least two hinges. Hinges are provided at both ends of the door body along the preset axis, and the hinges are configured to connect the door body and the box body.

[0016] In some embodiments, the hinge includes a mounting plate and a hinge shaft. The mounting plate is connected to the end face of the box body. The mounting plate extends beyond the side surface of the box body and covers at least part of the end face of the door body. The hinge shaft is connected to the mounting plate and inserted into the hinge hole on the end face of the door body.

[0017] In some embodiments, there are two door bodies, and the two door bodies can be opened and closed relative to each other to jointly close the access opening in the closed state. Each door body is connected to the box body through two hinges.

[0018] Based on the above technical solutions, the present disclosure has at least the following beneficial effects:

[0019] In the embodiment of the present disclosure, by setting a suitable distance between the preset axis and the first side wall, it is equivalent to reducing the distance between the preset axis and the first edge line. During the opening process of the door body, the movement trajectory of the first edge line is an arc with the preset axis as the center and OL1 as the radius. Since the distance between OL1 is reduced, it is beneficial to make the first movement trajectory of the first edge line always located inside the extension surface of the side wall of the box body. Therefore, when the refrigerator is embedded and installed in the wall, the reserved space on the side of the box body along the first direction can be reduced, so that the door body can be opened better.

It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0037] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0038] This disclosure provides a refrigerator, as Figures 1 to 5 shown. In some embodiments, the refrigerator includes a cabinet 1 and a door 2. Among them, the cabinet 1 is provided with an access opening 11; the door 2 is rotatably connected to the cabinet 1 around a preset axis O to open or close the access opening 11; the door 2 includes a first side wall 21 and a second side wall 22 which are oppositely arranged, the first side wall 21 is farther from the cabinet 1 than the second side wall 22, the distance between the preset axis O and the first side wall 21 is D, and the thickness of the door 2 is B, where D = (1 / 4 - 1 / 3)*B.

[0039] Among them, items can be placed into or taken out of the box body 1 through the access opening 11. The door body 2 has a fixed rotation axis and closes the access opening 11 in the closed state. The door body 2 has a first side wall 21 and a second side wall 22 that are oppositely arranged along the second direction y, and a third side wall 23 and a fourth side wall 24 that are oppositely arranged along the first direction x. The first side wall 21 is located on the side away from the box body 1, the second side wall 22 is located on the side close to the box body 1, the third side wall 23 is connected between the first side wall 21 and the second side wall 22 and is located on the outer side, that is, on the side close to the preset axis O, and the fourth side wall 24 is connected between the first side wall 21 and the second side wall 22 and is located on the side away from the preset axis O.

[0040] The third side wall 23 intersects with the first side wall 21 to form a first ridge line L1, and the third side wall 23 intersects with the second side wall 22 to form a second ridge line L2. The first movement trajectory of the first ridge line L1 during the opening or closing process of the door body 2 is located inside the extension plane N of the side wall of the box body 1, and the second movement trajectory of the second ridge line L2 during the opening or closing process of the door body 2 is located inside the extension plane N of the side wall of the box body 1.

[0041] For traditional refrigerators, as Figure 4 shown, the distance between the preset axis O' and the first side wall 21 is relatively large, generally greater than 1 / 3*B. During the opening process of the door body 2, the movement trajectory of the first ridge line L1 is an arc with the preset axis O' as the center and O'L1 as the radius. When the door body 2 is in a certain angular range during the opening process, the first ridge line L1 will exceed the extension plane N of the side wall of the box body 1. When the refrigerator is installed in an embedded manner, in order to ensure that the door body 2 can be smoothly opened to 90° or greater than 90°, a certain distance needs to be maintained between the side wall of the refrigerator and the wall.

[0042] As Figure 3 and Figure 5 shown, the refrigerator of the present disclosure moves the preset axis O a distance X outward along the second direction y relative to the preset axis O' of the prior art, reducing the value of D, which is equivalent to reducing the distance between the preset axis O and the first ridge line L1. During the opening process of the door body 2, the movement trajectory of the first ridge line L1 is an arc with the preset axis O as the center and OL1 as the radius. Since the distance between OL1 is reduced, it is beneficial to keep the first movement trajectory of the first ridge line L1 always inside the extension plane N of the side wall of the box body 1. The closer the distance between the preset axis O and the first side wall 21, the smaller the interference degree between the door body 2 and the side of the box body during the opening and closing. Therefore, when the refrigerator is embedded in the wall, the reserved space on the side of the box body 1 along the first direction x can be reduced, enabling the door body 2 to open better, and the door body 2 can be smoothly opened to 90° or greater than 90°.

[0043] Moreover, by setting the upper limit value of the D value, it is possible to prevent the door body 2 from exceeding the extension surface N during the opening process, enabling the door body 2 to open better; by setting the lower limit value of the D value, it is possible to prevent the distance between the hinge axis O and the first side wall 21 from being too small, resulting in insufficient strength at the hinge of the door body 2, and improving the structural reliability of the refrigerator.

[0044] In addition, after the hinge axis O moves outward along the second direction y, the greater the distance between the second ridge line L2 and the box body 1 during the rotation of the door body 2, so it is not easy to collide with the box body 1.

[0045] In some embodiments, as Figure 3 shown, the door body 2 further includes a third side wall 23, which is connected between the first side wall 21 and the second side wall 22 and is located on the side close to the preset axis O. The distance between the preset axis O and the third side wall 23 is E, and D≤E≤1.3D.

[0046] In this embodiment, by setting the lower limit value of E, it is possible to prevent the distance between the hinge axis O and the third side wall 23 from being too small, resulting in insufficient strength at the hinge of the door body 2, and improving the structural reliability of the refrigerator; by setting the upper limit value of E, so as to avoid that although the D value is reduced, a relatively large E value will still cause a relatively large distance between OL1, and a relatively small distance can be maintained between OL1, preventing the door body 2 from exceeding the extension surface N during the opening process, enabling the door body 2 to open better.

[0047] In some embodiments, the door body 2 further includes a third side wall 23, which is connected between the first side wall 21 and the second side wall 22 and is located on the side close to the preset axis O. A fillet 25 is provided between the first side wall 21 and the third side wall 23.

[0048] When a fillet 25 is provided between the first side wall 21 and the third side wall 23, the first ridge line L1 is a virtual line. In addition, a fillet 25 can also be provided between the fourth side wall 24 and the first side wall 21, and a fillet 25 can also be provided between the second side wall 22 and the fourth side wall 24.

[0049] In this embodiment, by setting the fillet 25, it is further possible to prevent the first ridge line L1 from exceeding the extension surface N during the opening process of the door body 2, and setting the fillet 25 can reduce the requirement for the distance that the preset axis O moves outward along the second direction y. By setting the fillet 25 and designing D within a suitable range, it can be well ensured that the door body 2 opens smoothly, which is beneficial to the embedded installation of the refrigerator.

[0050] In some embodiments, as Figure 3 shown, the radius of the fillet 25 is R, where R=(1 / 6 - 1 / 5)*B.

[0051] In this embodiment, the radius value of the rounded corner 25 is set within a suitable range, and the radius value is increased compared with the prior art, which can well ensure the smooth opening of the door body 2 and is beneficial to the built-in installation of the refrigerator. The larger the radius value of the rounded corner 25, the smaller the interference degree between the door body 2 and the side of the refrigerator during the opening and closing process. At the same time, considering the appearance requirements and actual practical situations, the radius value of the rounded corner 25 cannot be set too large.

[0052] In some embodiments, as Figure 3 shown, there is a gap A between the cabinet 1 and the door body 2, and D≤A≤1.3D.

[0053] After the preset axis O moves outward along the second direction y, the distance between the second edge line L2 and the cabinet 1 will also increase correspondingly during the rotation of the door body 2. In order to achieve better sealing, on the basis of the prior art, the preset axis O and the door body 2 can be moved as a whole towards the direction close to the cabinet 1 to reduce the gap A, which is beneficial to reducing the thickness dimension of the refrigerator along the second direction y.

[0054] By setting the lower limit value of the gap A in this embodiment, it can prevent the second edge line L2 from interfering with the cabinet 1 during the movement of the door body 2 and ensure the smooth opening of the door body 2; by setting the upper limit value of the gap A, it is beneficial to set a sealing component between the cabinet 1 and the door body 2 and improve the sealing effect between the cabinet 1 and the door body 2.

[0055] In some embodiments, the door body 2 further includes a third side wall 23, the third side wall 23 is connected between the first side wall 21 and the second side wall 22 and is located on the side close to the preset axis O. The third side wall 23 intersects with the first side wall 21 to form a first edge line L1, and the first movement trajectory A of the first edge line L1 during the rotation of the door body 2 is located inside the extension surface N of the side of the cabinet 1.

[0056] This embodiment can reduce the limitation on the installation space of the refrigerator. Even when the side wall of the cabinet 1 is in good contact with the wall or there is a good gap, the door body 2 can still be opened smoothly.

[0057] In some embodiments, as Figure 5 shown, starting from the closed state of the door body 2, the distance between the first movement trajectory A of the first edge line L1 and the extension surface N first decreases and then increases as the opening angle of the door body 2 increases; and / or the distance between the first movement trajectory A and the cabinet 1 decreases as the opening angle of the door body 2 increases.

[0058] In some embodiments, in the projection on the horizontal plane, the first movement trajectory A is arc-shaped and tangent to the extension surface N, and the tangent point is the first point a1 of the first movement trajectory A. The first point a1 is located on the first edge line L1 when the door body 2 is opened to a preset angle, and the preset angle is less than 90°. When tangent, the perpendicular line from the first point a1 to the preset axis O is parallel to the first direction x.

[0059] In this embodiment, when the door body 2 rotates to make the first ridge line L1 located at the outermost side, it can be tangent to the extension plane N, which can not only prevent the first ridge line L1 from exceeding the extension plane N during the rotation of the door body 2 to ensure the smooth opening of the door body 2, but also maximize the values of E and D on this basis to improve the strength of the door body 2 at the hinge. In addition, when the door body 2 is closed, it is also beneficial to make the third side wall 23 of the door body 2 flush with the side wall of the box body 1.

[0060] In some embodiments, as Figure 1 shown, the refrigerator further includes: at least two hinges 3, and hinges 3 are provided at both ends of the door body 2 along the preset axis O, and the hinges 3 are configured to connect the door body 2 and the box body 1. By arranging the hinges 3 at the top and bottom ends of the door body 2, the door body 2 can be stably rotated around the preset axis O. The hinge 3 is arranged at a position on the box body 1 close to the outside along the first direction x.

[0061] In some embodiments, as Figure 2 shown, the hinge 3 includes a mounting plate 31 and a hinge shaft 32. The mounting plate 31 is connected to the end face of the box body 1, the mounting plate 31 extends beyond the side face of the box body 1 and covers at least part of the end face of the door body 2, and the hinge shaft 32 is connected to the mounting plate 31 and inserted into the hinge hole on the end face of the door body 2. Specifically, the mounting plate 31 can be in a rectangular structure, one end of the mounting plate 31 is fixed to the top wall or the bottom wall of the box body 1, and the other end of the mounting plate 31 covers the top wall 26 or the bottom wall 27 of the door body 2.

[0062] In some embodiments, as Figure 1 shown, there are two door bodies 2, and the two door bodies 2 can be opened and closed relative to each other to jointly close the access opening 11 in the closed state. Each door body 2 is connected to the box body 1 through two hinges 3. The hinges 3 of the two door bodies 2 are located at both ends of the box body 1 along the first direction x. Optionally, only one door body 2 can also be provided.

[0063] Through reasonable design of the position of the preset axis O and setting appropriate fillet radius values in the above embodiments of the present disclosure, and in cooperation with the hinge 3, the built-in installation of the refrigerator can be realized. Further, the thickness of the door body 2 can be reduced, which is beneficial to the smooth opening of the door body 2. On the one hand, the appearance of the door body 2 can be guaranteed, and on the other hand, the door body 2 and the hinge 3 can have sufficient strength and stiffness. Without affecting the refrigeration performance of the refrigerator, it can be realized that all points on the first ridge line L1 and the second ridge line L2 do not exceed the extension plane N of the side face of the box body 1, and the zero-embedded and flat-embedded of the refrigerator can be realized. Zero-embedded means that the refrigerator door body 2 is flush with the wall, and flat-embedded means that the door body 2 extends beyond the wall, but the box body 1 is flush with the wall.

[0064] Based on the above embodiments of the present disclosure, without explicit negation or conflict, the technical features of one embodiment can be beneficially combined with one or more other embodiments.

[0065] Although some specific embodiments of the present disclosure have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and not for limiting the scope of the present disclosure. Those skilled in the art should understand that the above embodiments can be modified or some technical features can be equivalently replaced without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
