The free embedded refrigerator provided by the invention can realize free switching between two using modes of free placement and embedded placement of the refrigerator, and meets various requirements of different using groups.
In order to ensure that the motion track of the door 22 in the rotation process is always in the range between the left side and the right side of the box 21, that is, the motion track of the door 22 in the rotation process is ensured not to exceed the width of the box 21. The embodiment adopts the following door body design method and technical scheme: referring to fig. 3 to 7, in the free-insertion refrigerator provided by the present invention, the door 22 includes a left side surface, a chamfer transition surface 222, a front side surface laterally distributed left and right, and a top surface provided with a shaft hole corresponding to the hinge shaft 231, the front end of the left side surface of the door 22 and the left end of the front side surface are in arc smooth transition connection through the chamfer transition surface 222, and the left side surface of the door 22 is relatively located at the inner side of the left side surface of the refrigerator body 21; the vertical distance between the shaft hole of the hinge shaft 231 and the left side surface of the box body 21 is a, the maximum vertical distance between the shaft hole of the hinge shaft 231 and the chamfer transition surface 222 is b, and a is more than or equal to b and is greater than 0.

To some refrigerators probably have the door body and open 90 and inconvenient the interior drawer box of taking out of box, put the condition of thing board, accessible conventional technology reduces a body thickness or shortens modes such as walk-in, freezer, drawer box, put thing board width and solve with the suitability, this embodiment department does not give concrete size restriction, as long as can conveniently take out the interior drawer box of box and put the article such as thing board can, this embodiment is no longer repeated here.
In order to further embody the effect brought by the numerical relationship of a and b in the door body of the invention, reference can be made to the structural size relationship of the traditional refrigerator door shown in fig. 2, in the structural shape of the traditional refrigerator door, the vertical distance between the hinge shaft hole and the left side surface of the refrigerator body is a ', the maximum vertical distance between the hinge shaft hole and the chamfer transition surface is b ', the central angle of the chamfer transition surface is R ', the movement track of the refrigerator door in the rotating process exceeds the width of the refrigerator body, and when the refrigerator body is matched with small gaps at the left side and the right side of the accommodating space, the door body can touch the side wall of the accommodating space, so that the appearance of the door body is damaged, and even the door body can not be opened by. The door body provided by the invention has a value more than or equal to b, so that the motion trail of the door body rotating around the hinge shaft can be relatively positioned between the left side surface and the right side surface of the refrigerator body, and the door body can be smoothly opened by 90 degrees when the refrigerator body is in small clearance fit with the left side surface and the right side surface of the cabinet accommodating space.
In order to realize the numerical relationship of a being more than or equal to b in the door body and ensure that the door body is opened for 90 degrees, the invention can start from two directions of increasing the value a and reducing the value b, and concretely provides the following three implementation schemes, but the protection scope of the invention is not limited to the following three implementation schemes, and the invention belongs to the protection scope of the invention as long as the technical means which accord with the working principle of the invention and can satisfy the numerical relationship of a being more than or equal to b in the door body are adopted.
Specifically, a first class of implementation schemes realized by the numerical relationship of a and b in the door body are as follows: as shown in fig. 3 to 5, the left side surface of the door 22 is designed as an inclined surface 221 which is distributed from back to front and is inclined towards the inner side of the refrigerator, and the front end of the inclined surface 221 is connected with the left end of the front side surface through a chamfer transition surface 222; the inclined distribution of the inclined surface 221 is utilized to enlarge the vertical distance between the front end of the inclined surface 221 and the left side surface of the box body 21, reduce the b value of the maximum vertical distance between the chamfer transition surface 222 and the shaft hole of the hinge shaft 231 and realize the numerical relation of a being more than or equal to b. In the embodiment, the left side surface of the door body is changed from the traditional parallel distribution with the left side surface of the refrigerator body into the inclined distribution towards the inner side of the refrigerator, namely, the chamfer transition surface 222 can move towards the inner side of the refrigerator, and the maximum distance between the hinge shaft hole and the chamfer transition surface is shortened under the condition that the distance between the hinge shaft hole and the left side surface of the refrigerator body is kept unchanged, so that a is larger than or equal to b. Fig. 4 shows a schematic diagram of the chamfer transition surface of the present embodiment in a state of minimum distance from the left side surface of the box body during rotation, and fig. 5 shows a schematic diagram of the door body in a state of 90 ° open.
The second type of implementation scheme of the numerical relationship that a is more than or equal to b in the door body is as follows: referring to FIG. 6, by enlarging the value of the central angle R of the chamfer transition surface 222 and satisfying that R is less than or equal to 90 degrees, the value b of the maximum vertical distance between the chamfer transition surface 222 and the shaft hole of the hinge shaft 231 is reduced, and the numerical relationship of a being greater than or equal to b is realized. Compared with the graph in FIG. 6 and FIG. 2, the door body of the invention realizes that R is greater than R' by increasing the central angle of the chamfer transition surface, and shortens the maximum distance between the hinge shaft hole and the chamfer transition surface under the condition of keeping the distance between the hinge shaft hole and the left side surface of the box body unchanged, thereby realizing that a is greater than or equal to b.
The third type of implementation scheme of the numerical relationship that a is more than or equal to b in the door body is as follows: referring to fig. 7, the vertical gap distance between the left side of the door 22 and the left side of the box 21 is enlarged, as shown by the value c in fig. 7, so that the vertical distance a between the hinge shaft hole and the left side of the box is enlarged, and the numerical relationship of a ≧ b is realized. The left side face of the traditional door body is flush with the left side door of the box body or has a small vertical distance, the vertical gap distance between the left side face of the traditional door body and the left side door of the box body is enlarged, and the distance between the hinge shaft hole and the left side face of the box body is enlarged under the condition that the maximum distance between the hinge shaft hole and the chamfer transition face is kept unchanged, so that a is larger than or equal to b.
Through the structural design of the door 22, when the refrigerator body 2 is embedded into the accommodating space 11 of the cabinet 1, the door 22 can be freely opened by 90 degrees without touching the side wall of the accommodating space 11. Moreover, in order to better help the door body 22 to realize the limitation of the maximum rotation angle, the invention also provides a limiter 5. By using the limiter 5, when the refrigerator body 2 is embedded into the cabinet 1, the door 22 can be assisted to be opened and can be opened only by 90 degrees to the maximum extent, when the refrigerator body 2 is moved out of the cabinet 1 and freely placed in an indoor hall, the angle at which the door 22 is opened is enlarged (because the problem that the door body rotates to touch the side wall of the cabinet is not considered at this time, the door body has a larger opening angle range and is more helpful to use), and the limiter 5 can assist the door 22 to be opened and can be opened only by 140 degrees to the maximum extent. When the refrigerator body 2 is switched between the free placement state and the embedded placement state, the two types of switching selection of the maximum rotation angle are provided for the door body 22 by using the stopper 5, and the condition that the door body 22 is opened for use is better met.
The stopper 5 provided by the invention has the specific structural characteristics that: referring to fig. 8 to 14, the free-insertion refrigerator further includes a stopper 5 for limiting a maximum rotation angle of the door 22, a stopper column 223 is fixed at the bottom of the door 22, the stopper 5 includes a lower hinge plate 51, a hinge column 52 rotatably connected to the bottom of the door 22, a stopper disc 53 having a middle portion provided with a sleeve hole 531 corresponding to the hinge column 52, a fixing screw 55, and a lower door closer 54 having a mounting hole 541 corresponding to the hinge column 52 and a through hole 542 corresponding to the fixing screw 55, the lower hinge plate 51 includes a mounting portion 511 for fixing to the bottom of the refrigerator body 21 and a supporting portion 512 integrally formed with the mounting portion 511, the supporting portion 512 is provided with a fixing hole 515 corresponding to the fixing screw 55, the hinge column 52 is vertically fixed to the supporting portion 512, the stopper disc 53 is sleeved on the hinge column 52 through the sleeve hole 531, the lower door closer 54 is sleeved on the hinge column 52 through a mounting hole 541 and is positioned above the limiting disc 53; the limiting plate 53 is characterized in that a limiting block 532 extends outwards from the circumferential edge of the limiting plate 53, two limiting grooves which are circumferentially distributed by taking the hinge column 52 as a circle center and correspond to the limiting block 532 are formed in the edge of the supporting portion 512, and the two limiting grooves are a first limiting groove 513 and a second limiting groove 514 which is distributed at intervals with the first limiting groove 513.
Referring to fig. 9 and 10, when the stopper 532 of the stopper disc 53 is engaged with the first stopper groove 513 or the second stopper groove 514, and the rear lower door closer 54 is mounted, the position of the stopper disc 53 and the lower door closer 54 is fixed by screwing the fixing screw 55 through the through hole 542 and the fixing hole 515 of the support part 513 of the lower hinge plate 51. When the fit between the limit block 532 and the limit groove needs to be switched, the connection between the fixing screw 55 and the lower hinge plate 51 is released, the limit disc 53 is rotated and adjusted to enable the limit block 532 to be clamped and matched with a proper limit groove (the first limit groove 513 or the second limit groove 514), and then the fixing screw 55 is fixedly connected with the lower hinge plate 51 again.
The principle of limiting the maximum opening angle of the door body by using the stopper 5 is as follows: referring to fig. 11 and 12, when the limiting block 532 is clamped into the first limiting groove 513, the limiting column 223 rotates 90 degrees along with the door 22 in the self-closing state and then abuts against the limiting block 532, that is, the first limiting groove 513 is formed at a proper position of the lower hinge plate 51, when the limiting block 532 of the limiting disc 53 is clamped and matched in the first limiting groove 513, after the door 22 is opened for 90 degrees, the limiting column 223 at the bottom of the door 22 is prevented by the limiting block 532 from continuing to rotate, and further, the door 22 cannot continue to rotate, so that the limitation on the maximum rotation angle of 90 degrees of the door 22 is realized, and the limitation condition is suitable for the use mode when the refrigerator body 2 is embedded into the accommodating space 11 of the cabinet 1. Referring to fig. 13 and 14, when the limiting block 532 is clamped into the second limiting groove 514, the limiting column 223 rotates 140 degrees along with the door 22 in the self-closing state and then abuts against the limiting block 532, that is, the second limiting groove 514 is formed at another suitable position of the lower hinge plate 51, when the limiting block 532 of the limiting disc 53 is clamped and matched into the second limiting groove 514, after the door 22 is opened for 140 degrees, the limiting column 226 at the bottom of the door 22 is prevented from continuing to rotate by the limiting block 532, further, the door 22 cannot continue to rotate, and limitation of the maximum rotation angle of 140 degrees of the door 22 is realized, and this limitation condition is suitable for a use mode when the refrigerator body 2 is freely placed in an indoor hall (non-cabinet).
