Assuming that the distance from the door rotation axis to the origin is R ₁ , the origin of the door 2 moves on a circle with the axis (x, y) as the center and a radius of R ₁ during the rotation of the door 2. In order to avoid the door 2 Interfering with the cabinet 4, it is necessary to ensure that the origin does not interfere with the cabinet 4, so the following conditions need to be met: R ₁ -x≤A and x ² +y ² =R ₁ ² , if R ₁ -x=A, then after conversion Obtain: x ² +y ² =(x+A) ² , decompose the formula to get the above formula x=(y2-A2)/2A.

Further, the distance between the pivoting side 21 of the door body 2 and the cabinet 4 is between 4 mm and 6 mm, reducing the gap between the built-in refrigerator and the cabinet 4 can enhance the Describe the integrated effect of the built-in refrigerator.

In a specific embodiment, the distance between the pivoting side 21 of the door body 2 and the cabinet 4 is 4mm. At this time, the intersection distance between the first limiting line E and the pivoting side 21 The distance between the first end M is 5.6 mm, and the angle between the first limiting line E and the front wall 22 of the door body 2 is 23°.

When the rotation axis of the door body is located on the curve as the second limit line, the distance between the rotation axis center of the door body and the second end N It is equal to the distance between the center of rotation of the door body and the box body 1 , during the rotation process of the door body, the second end is tangent to the box body. Wherein, B represents the distance between the door body 2 and the box body 1 when the door body is in a closed state, and T represents the thickness value of the door body 2 .

Assuming that the distance from the rotation axis of the door 2 to the point N at the second end is R ₂ , and the distance from the rotation axis of the door to the rear wall 24 is C, then during the rotation of the door 2, the point N is at The axis (x, y) is moving on a circle with a center radius of R _2. In order to avoid interference between the door body 2 and the box body 1, it is necessary to ensure that point N does not interfere with the box body 1, so the following conditions need to be met: R ₂ - C≤B, y=TC and x ² +C ² ＝R ₂ ² , take R ₂ -C=B, then it can be obtained after conversion: thus: x ² +C ² ＝(C+B) ² , The formula can be decomposed to get: C=(x ² -B ² )/2B, which can be substituted into y=TC to get the formula y=T-(x ² -B ² )/2B.

Further, in an embodiment where the distance between the pivoting side 21 of the door body 2 and the cabinet is 4mm, the second limiting line F can be set to be aligned with the rear wall 24 of the door body 2 The distance L ₂ between the intersection point of and the second end N is 16.2mm, and the angle β between the second limiting line F and the pivoting side 21 is 18°. At this time, the door body rotates The distance between the axis center and the second end N is not less than the distance between the door body rotation axis center and the box body 1, which can ensure that the door body 2 and the box body 1 without interference.

Further, the distance between the rotation axis of the door body and the front wall 22 of the door body 2 is no less than the distance between the rotation axis of the door body and the pivoting side 21 . Therefore, when the door body rotates to 90°, the gap between the door body 2 and the cabinet 4 becomes smaller than the gap between the door body 2 and the cabinet 4 when it is in the closed state. , That is, when the door body is opened to 90°, it will not move inward, and will not affect the user's access to items.

Specifically, the hinge installation side 23 of the door body 2 has a third limit line G passing through the first end, and the third limit line G is connected to the front wall 22 of the door body 2 and the hinge. The included angles between the turning sides 21 are the same. The rotation axis of the door body is located on the third limiting line G or on a side of the third limiting line G facing the pivoting side 21 . The distance between the center of rotation of the door body and the front wall 22 of the door body 2 is not less than the distance between the center of rotation of the door body and the pivotal side 21.

The third limiting line G can take the first intersection line of the front wall 22 of the door body 2 in the closed state and the hinge installation side 23 of the door body 2 as the X axis, so that the front wall 22 in the closed state The second intersection line between the pivoting side 21 of the door body 2 and the hinge installation side 23 of the door body 2 is the Y axis, and the intersection of the X axis and the Y axis is taken as the origin O, thereby constructing an XY coordinate system; then It is obtained by drawing in the XY coordinate system according to the formula x=y.

It can be understood that those skilled in the art can select the above-mentioned first limit line E, second limit line F, and third limit line G according to actual needs. After the target area is defined by the first limit line E and the second limit line F, in order to prevent the door body 2 from interfering with the cabinet 4 during rotation, or to prevent the door body 2 from interfering with the cabinet 1 during rotation, the door body 2. The axis of rotation of the door body must be debugged in the target area or on the boundary line of the target area. Then the specific position of the rotation axis of the door body can be finally determined according to whether the gap between the door body 2 and the cabinet 4 needs to be constant or small when the door body 2 is rotated to 90°. Therefore, those skilled in the art can know how to adjust and the adjustment area when adjusting the rotation axis of the door body, which provides theoretical basis support for those skilled in the art.

To sum up, in the built-in refrigerator of the present invention, by setting the first limit line E on the hinge installation side 23 of the door body 2, the staff can be on the first limit line E or on the first limit line.
