Some embodiments of the present disclosure provide a refrigerator 1 . Referring to FIGS. 1 and 2 , the refrigerator 1 includes a box body 10 , a door body 20 and a hinge assembly 30 .

The box body 10 includes an inner container, an outer shell and a heat insulation layer. The inner container is roughly in the shape of a rectangular box, and a storage room 11 is defined therein. The shape of the outer casing matches the shape of the inner container, and the inner container is arranged in the outer casing. The heat insulation layer is disposed between the inner container and the outer shell to block the heat transfer between the storage chamber and the outer space of the box body 10 .

One side (for example, the front side) of the storage room 11 is opened to form an access opening 12 . The storage room 11 is configured to store food, and a user can put food into the storage room 11 or take out food from the storage room 11 through the access opening 12 .

In some embodiments, the refrigerator 1 further includes a refrigeration device including an evaporator, a compressor, a condenser and an expansion device. The refrigerating device lowers the temperature of the air through latent heat of evaporation of the refrigerant, thereby providing cold air for the storage room 11 .

In some embodiments, the storage room 11 is divided into a refrigerator room and a freezer room. The refrigerating room can maintain the temperature of the air inside it at about 0° C. to 5° C. and store food in a refrigerating mode. The freezer can maintain the temperature of the air inside it at about -30°C to 0°C, and store food in a freezing mode. In addition, the box body 10 may also include other chambers, for example, a vacuum chamber, a constant temperature chamber, and the like.

In some embodiments, the refrigerator compartment and the freezer compartment are arranged along the height direction of the refrigerator 1 . For example, the refrigerating compartment is located below the freezing compartment. It should be noted that, in some embodiments, the refrigerator compartment and the freezer compartment may be arranged in other ways, which is not limited in the present disclosure.

The door body 20 is connected to one end (such as the front end) of the box body 10 through a hinge assembly 30 . The door body 20 can be rotated to open or close the storage compartment 11. When the door body 20 is opened, the access opening 12 allows food to be put in or taken out.

Referring to FIG. 1 , the hinge assembly 30 is, for example, a first hinge assembly 40 or a second hinge assembly 50 . The first hinge assembly 40 is arranged on the upper part of the box body 10, and is fixedly connected with the box body 10 and the door body 20 respectively; the second hinge assembly 50 is arranged at the lower part of the box body 10, and is respectively fixed with the box body 10 and the door body 20 connect. The first hinge assembly 40 and the second hinge assembly 50 are arranged along the same axis, so that the door body 20 can rotate around the axis to realize the opening and closing of the door body 20 .

Normally, the hinge assembly 30 is located on the left or right side of the door body 20 . Referring to FIGS. 1 and 2 , the door body 20 includes a left side wall, a right side wall, an upper side wall, a lower side wall and a front side wall. For the convenience of description, the side wall closer to the hinge assembly 30 among the left side wall and the right side wall of the door body 20 is called the door side wall 21 .

For example, in Fig. 1 and Fig. 2, the hinge assembly 30 is arranged on the left end of the door body 20 (that is, the user's right end), then the left side wall of the door body 20 is called the door side wall 21, and the right end of the door body 20 is referred to as Its left end is the center of rotation for rotating motion.

Similarly, when the hinge assembly 30 is arranged at the right end of the door body 20 , the right side wall of the door body 20 is called the door side wall 21 , and the left end of the door body 20 rotates with its right end as the rotation center.

In some embodiments, referring to FIG. 1 , FIG. 2 and FIG. 4 , the side wall (for example, the front side wall) away from the box body 10 when the door body 20 is closed is called the door front wall 22 , and the door body 20 is closed when it is closed. The side wall (eg, the rear side wall) close to the box body 10 is called the door rear wall 23 . The intersection of the door front wall 22 and the door side wall 21 forms a side edge K.

It should be noted that when the door front wall 22 and the door side wall 21 are both planes, the intersection line of the two planes is the theoretical side edge K. In actual processing and production, the intersection of the door front wall 22 and the door side wall 21 is usually rounded and transitioned. In this way, the intersection of the door front wall 22 and the door side wall 21 forms a curved surface, and any straight line extending along the height direction (ie, up and down direction) of the refrigerator 1 on the curved surface can represent the side edge K.

The box body 10 includes a left side wall, a right side wall, an upper side wall, a lower side wall and a rear side wall. In some embodiments, the plane where the side wall near the hinge assembly 30 of the left and right side walls of the box body 10 is located is defined as the reference plane M. As shown in FIG. Taking the reference plane M as the interface, the side where the box body 10 is located is defined as the inner side, and the opposite side is defined as the outer side. In FIG. 1 and FIG. 2 , the hinge assembly 30 is arranged at the left end of the box body 10 , then the left side wall of the box body 10 is defined as a reference plane M, and the inner side is the right side of the reference plane M.

It can be understood that when the hinge assembly 30 is arranged at the right end of the box body 10 , the right side wall of the box body 10 is defined as a reference plane M, and the inner side is the left side of the reference plane M.

Referring to Fig. 2, when the refrigerator 1 is embedded in the cabinet 100, considering factors such as uneven ground or deformation of the cabinet, it is necessary to reserve a first space between the outer wall of the refrigerator 1 (where the corresponding reference plane M is located) and the inner wall of the cabinet 100. The gap Y, the width of the first gap Y is usually any value between 3mm and 5mm, for example, the width of the first gap Y can be 3mm, 4mm or 5mm.

It can be understood that, in order to ensure the normal opening of the door body 20, during the rotation of the door body 20, the side edge K exceeds the distance of the reference plane M (that is, as the door body 20 rotates, when the side edge K exceeds the distance from the reference plane M When moving to the outer side, the distance between the side edge K and the reference plane M) should not be too large, for example, the distance should not be greater than 5mm. Otherwise, the side edge K will collide with the cabinet 100 , causing the door body 20 to not be fully opened, thereby causing damage to the door body 20 or the cabinet 100 .

For this reason, referring to FIG. 3 , the hinge assembly 30 is in the form of a double-axis (comprising a Leroux triangle block and a positioning shaft) hinge, so that when the door body 20 rotates, its side edge K moves to the inner side, thereby preventing the side edge K from colliding with Cabinet 100 bumps.

In some embodiments, as shown in FIGS. 2 to 4 , the first hinge assembly 40 includes a hinge plate 410 , a positioning shaft 420 , a Rero triangle block 430 , a positioning slot 440 and a guide slot 450 .

The hinge plate 410 includes a connecting portion 411 and an extending portion 412 connected with the connecting portion 411 and extending horizontally. The connecting portion 411 is fixedly connected to the upper side wall of the box body 10 . The connecting part 411 has a plurality of first through holes 4111, and the box body 10 has a plurality of second through holes 13, and the plurality of second through holes 13 are located in the upper side wall of the box body 10 and are aligned with the plurality of first through holes 4111. One-to-one correspondence, the first connecting portion 411 can be fixedly connected to the box body 10 through fasteners such as screws.

The Reuleaux triangle block 430 is a flat plate in the shape of a Reuleaux triangle. A side wall of the Rero triangle block 430 is attached to a lower side wall of the extension part 412 and is fixedly connected with the extension part 412 . The positioning shaft 420 is located on a side (lower side) of the Rero Triangular block 430 away from the extension portion 412 , and is fixedly connected to the Rero Triangular block 430 . The positioning axis 420 is perpendicular to the Rero Triangular block 430 (ie, the central axis of the positioning shaft 420 is perpendicular to the Rero Triangular block 430 ).

What needs to be explained is that the Relos triangle is a curved-sided triangle with each vertex of an equilateral triangle as the center, the side length of the equilateral triangle as the radius, an arc between the other two vertices, and three arcs.

In some embodiments, the connecting part 411 and the extension part 412 are integrally formed, and the hinge plate 410, the positioning shaft 420 and the Rero triangular block 430 are integrally formed, or the hinge plate 410, the positioning shaft 420 and the Rero triangular block 430 are divided into two parts. The body part, and the hinge plate 410, the positioning shaft 420 and the Rero triangular block 430 can be assembled and fixed by welding or threaded connection.

The door body 20 includes a first guide bar 210 and a second guide bar 220 . The first guide bar 210 and the second guide bar 220 are located on the upper side wall of the door body 20 and protrude upward. The first guide bar 210 and the second guide bar 220 extend along the thickness direction of the door body 20 and are spaced apart along the width direction of the door body 20 to define a guide groove 450 . The first guide bar 210 is farther away from the door side wall 21 than the second guide bar 220 . The guide groove 450 extends along the thickness direction of the door body 20 and is parallel to the door side wall 21 .

The bottom of the guide groove 450 is recessed downward to form the positioning groove 440 . The positioning groove 440 extends along the width direction of the door body 20 and is parallel to the front wall 22 of the door.

In some embodiments, the guide groove 450 is formed in the upper sidewall of the door body 20 , that is, the upper sidewall of the door body 20 is recessed downward to form the guide groove 450 .

As shown in FIG. 3 , the first guide bar 210 and the second guide bar 220 are separated by a first predetermined distance E, that is, the width of the guide groove 450 in the width direction of the door body 20 is E. The side length of the regular triangle defined by the Reroux triangle block 430 is approximately equal to the first predetermined distance E.

The positioning shaft 420 is inserted in the positioning slot 440 and matched with the positioning slot 440 ; the Leroux triangle block 430 is inserted in the guiding slot 450 and matched with the guiding slot 450 . When the door body 20 rotates, the positioning shaft 420 relatively moves in the positioning groove 440 , and the Rero triangular block 430 relatively moves in the guide groove 450 . When the Relo triangular block 430 relatively moves in the guide groove 450, the Relo triangular block 430 is in contact with the first guide bar 210 and the second guide bar 220, and the Relo triangular block 430 is tangent to the first guide bar 210 and the second guide bar 220. At least one of the two guiding strips 220 .

In this way, the box body 10 and the door body 20 are connected through the first hinge assembly 40 , and the door body 20 can rotate relative to the box body 10 through the first hinge assembly 40 .

It should be noted that some embodiments of the present disclosure are not limited to disposing the positioning shaft 420 and the Rero triangle block 430 on the hinge plate 410 .

For example, the positioning shaft 420 and the Relo triangle block 430 are arranged on the door body 20, and the positioning groove 440 and the guide groove 450 are arranged in the hinge plate 410; One of the) and a groove (that is, one of the positioning groove 440 or the guide groove 450) are arranged on the hinge plate 410, and the other axis (that is, the other of the positioning axis 420 or the Rero triangle block 430 ) or another groove (ie, the other one of the positioning groove 440 or the guide groove 450 ) is provided on the door body 20 . For ease of description, the following mainly takes the positioning shaft 420 and the Relo triangle block 430 disposed on the hinge plate 410 as an example, and the positioning groove 440 and the guide groove 450 are disposed on the door body 20 as an example. limits.

It should be noted that the structure of the second hinge assembly 50 is substantially the same as that of the first hinge assembly 40, the only difference being:

The second hinge assembly 50 is located at the lower part of the box body 10 , the connection portion of the second hinge assembly 50 is fixedly connected to the front end of the box body 10 , and the extension portion of the second hinge assembly 50 is substantially perpendicular to the connection portion.

After the hinge plate 410 is fixedly connected to the box body 10, and the positioning shaft 420 and the Reloux triangle block 430 are fixedly connected to the hinge plate 410, the box body 10 remains stationary during the rotation of the door body 20 relative to the box body 10, so Hinge plate 410, positioning shaft 420 and Rero triangle 430 also remain stationary. At this time, the positioning slot 440 will move relative to the positioning shaft 420 , and the guide slot 450 will move relative to the Rero triangle block 430 . However, it can be understood that there is a relative motion relationship between the positioning groove 440 and the positioning shaft 420, and between the guide groove 450 and the Rero triangle block 430. For the convenience of description, some embodiments of the present disclosure are sometimes referred to as the positioning groove 440 and the guide The slot 450 is a static reference object, the positioning shaft 420 moves in the positioning slot 440 , and the manner in which the Rero triangular block 430 moves in the guide slot 450 is described. However, this should not be construed as a limitation of the present disclosure.

In some embodiments, as shown in FIG. 5 , the central trajectory of the positioning groove 440 is a positioning trajectory S, and the positioning trajectory S is a straight line segment. One end of the positioning trajectory S is farther away from the door side wall 21 than the other end of the positioning trajectory S, and the positioning trajectory S is parallel to the door front wall 22 . The orthographic projection of the central axis of the positioning shaft 420 on the bottom of the positioning groove 440 is the positioning center point P. During the opening process of the door body 20, the positioning center point P moves toward the direction close to the door side wall 21 along the positioning track line S, so that the door body 20 moves a certain distance to the inner side while rotating, so that the door body can be avoided. 20 collided with cabinet 100.

The point where the center of the equilateral triangle defined by the Reroux triangle block 430 is defined as the guide center point O, that is, the orthographic projection of the central axis of the Reroux triangle block 430 on the groove bottom of the guide groove 450 is the guide center point O. The Reroux triangle block 430 includes three vertices, and these three vertices are successively recorded as the first vertex A, the second vertex

One side surface of 220 is tangent to the third midpoint C _m , and the line segment AB is parallel to the door side wall 21 .

The positioning axis 420 is disposed on the Reroux triangle block 430 and is close to any one of the three vertices. For example, the positioning axis 420 is close to the first vertex A, and the positioning center point P is located on the line segment OA.

In some embodiments, line segment OP is longer than line segment AP. Wherein, the line segment OP is denoted as the axis line segment OP.

In some embodiments, the first vertex A of the Reroux triangle 430 is closer to the box 10 than the third vertex C, and the third top and bottom C is closer to the box 10 than the second vertex B. That is to say, the distances between the first vertex A, the third vertex C, and the second vertex B and the end surface of the box body 10 near the door body 20 increase sequentially.

It can be understood that the positioning axis 420 is close to the first vertex A, and the first vertex A is close to the box body 10, so as to increase the distance that the door body 20 moves to the inside during the opening process, and avoid collision between the side edge K and the cabinet 100 .

As shown in FIG. 5 to FIG. 10 , the movement of the positioning shaft 420 along the positioning slot 440 is equivalent to the movement of the positioning center point P along the positioning track S.

Since the hinge plate 410 is fixedly connected to the box body 10 and the Relo triangular block 430 respectively, and the positioning shaft 420 is fixedly connected to the Rero triangular block 430, therefore, the Relo triangular block 430 and the positioning shaft 420 are both stationary relative to the box body 10, That is to say, the movement of the Rero triangle block 430 relative to the guide groove 450 is equivalent to the movement of the box body 10 relative to the door body 20 .

Similarly, the axial line segment OP is stationary relative to the Rero triangular block 430, therefore, the movement of the axial line segment OP relative to the guide groove 450 is equivalent to the movement of the Rero triangular block 430 relative to the guide groove 450, and is also equivalent to the movement of the box body 10 relative to the movement of the door body 20.

In the following description, for the convenience of explanation, the movement of the positioning center point P along the positioning trajectory S will be used to represent the movement of the positioning shaft 420 along the positioning groove 440, and the movement of the axis line segment OP relative to the guide groove 450 will be used to represent the Reroux triangle block 430 Movement relative to guide slot 450.

As shown in FIG. 5 , the positioning trajectory S includes a first positioning end point P ₀ and a second positioning end point Pe. The first positioning end point P ₀ and the second positioning end point Pe are two ends of the positioning track line S, and the second positioning end point Pe is closer to the door side wall 21 than the first positioning end point P ₀ . The positioning trajectory line S is perpendicular to the door side wall 21 and parallel to the door front wall 22 .

In some embodiments, the distance between the positioning trajectory line S and the door front wall 22 is the third preset distance D1, the distance between the positioning trajectory line S and the door rear wall 23 is the fourth preset distance D2, and the third preset distance D1>the fourth preset distance D2. For example, the ratio of the third preset distance D1 to the fourth preset distance D2 is greater than 1 and less than or equal to 3. For example, the ratio of the third preset distance D1 to the fourth preset distance D2 is 3, 2 or 3/2.

It can be understood that when the user opens the door body 20 , the force exerted on the door body 20 mainly acts on the side of the door body 20 that is close to the door front wall 22 and away from the door side wall 21 . Therefore, the positioning groove 440 is set closer to the door rear wall 23 (relative to the door front wall 22), so that when the door body 20 is opened by the user, the positioning shaft 420 is located on the door body 20 away from the door front wall 22 and close to the door side wall. 21, so that the force on the door body 20 can be balanced. In this way, it is beneficial to improve the smoothness and stability of the door body 20 during the opening process, and can improve the strength of the door body 20 and the positioning groove 440 .

In some embodiments, the fourth preset distance D2 is any value between 13mm and 17mm, for example, the third preset distance D1 is 30mm, and the fourth preset distance D2 is 15mm.
