[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0042] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0043] In the prior art, for built-in refrigerators installed in cabinets, when the door is opened, the corner of the door cannot exceed the size of the cabinet too much, and the corner will interfere with the cabinet, often causing the door to open at an angle less than 90°, thereby affecting the removal of items from the storage compartment in the cabinet. At present, the conventional practice is to connect the door to the cabinet through a double-axis hinge to ensure that the door can be opened at 90° relative to the cabinet. Although such a setting ensures the opening angle of the door, the connection method of the double-axis hinge is relatively complicated and there is a problem of high manufacturing cost. In order to solve this problem in the prior art, the present invention provides a built-in refrigeration device.

[0044] like Figure 1-3As shown, an embedded refrigeration device provided by an embodiment of the present invention includes a cabinet 1 and a refrigerator 2, wherein the refrigerator includes a box body 21 and a door body 22 having a storage compartment 211, the cabinet 1 has an installation cavity for installing the box body 21, the box body 21 is installed in the installation cavity, and the door body 22 is pivotally connected to the cabinet 1 for opening and closing the storage compartment 211.

[0045] This new embedded refrigeration device directly connects the door body 22 to the cabinet 1 through an ordinary single-axis rotating hinge or a folding hinge, avoiding interference between the corners of the door body 22 and the cabinet 1 when the door body 22 is opened, thereby ensuring that the opening angle of the door body is greater than or equal to 90°. The prices of single-axis rotating hinges and folding hinges are generally lower than those of double-axis rotating hinges. Such a setting can reduce the cost of refrigerator manufacturing.

[0046] In an embodiment of the present invention, Figure 1 As shown in FIG. 3, the door body is pivotally connected to the box body via a hinge 3. The hinge 3 is preferably a folding hinge, which has the advantages of low cost and easy installation.

[0047] For the detailed structure of hinge 3, refer to Figure 3 The hinge 3 includes a first hinge leaf 31, a second hinge leaf 32 and a hinge pin 33. The first hinge leaf and the second hinge leaf include plane parts 311, 321 and hinge joints 312, 322 respectively. The hinge pin 33 is inserted into the hinge joint 312 of the first hinge leaf and the hinge joint 322 of the second hinge leaf.

[0048] During installation, the plane portion 311 of the first hinge leaf and the plane portion 321 of the second hinge leaf are usually used to connect with the cabinet 1 or the door body 22 .

[0049] In some embodiments, when the door body 22 closes the storage compartment 211, the planar portion 311 of the first hinge leaf and the planar portion 321 of the second hinge leaf are folded, and one of them is connected to one of the left and right side walls of the installation cavity, and the other is connected to the door side wall of the door body relative to the aforementioned side wall.

[0050] It should be noted that, when arranged in this way, it is necessary to ensure that the hinge pin 33 is located at the front side of at least one of the side wall of the installation cavity and the door side wall, so as to ensure that the door body can be opened to at least 90°.

[0051] Figure 4a-4c An embodiment of the above connection method is shown, and specific reference is made to Figure 4a , is a schematic diagram of the structure in which the door body 22 is closed on the storage compartment 211. It can be understood that in this embodiment, the door body 22 is located inside the installation cavity of the cabinet 1.

[0052] Then go to Figure 4b , it can be seen that the hinge pin 33 is located at the front side of the door body 22, but the hinge pin 33 is not located at the front side of the cabinet side wall. Figure 4c When arranged in this way, due to the interference of the side wall of the installation cavity of the cabinet 1, the limit position of the door body 22 opening is 90°.

[0053] As a preferred embodiment, refer to Figure 5a-5c In this arrangement, the hinge pin 33 is located on the side wall of the installation cavity and the front side of the door side wall. Figure 5b , Figure 5c Compared with the above arrangement, in this arrangement, when the door body 22 is pivoted relative to the cabinet 1, the maximum opening angle thereof can exceed 90°, reach 180°, or even exceed 180°. In this case, the door body 22 can be opened and folded onto the front surface of the cabinet 1. It can be understood that in this case, it is convenient for the user to take the stored food from the storage compartment 211.

[0054] It should be noted that if a drawer is provided in the storage compartment 211, since the door body 22 is completely attached to the front surface of the cabinet 1, this arrangement can also overcome the interference caused by the thickness of the door body 22 when the drawer is pulled out of the storage compartment, and can facilitate the pulling out of the drawer.

[0055] In the above method, optionally, when the cabinet 1 and the door body 22 are connected by the hinge 3, the connection position of the first hinge leaf 31, the second hinge leaf 32 and the cabinet 1 or the door body 22 can be adjusted so that when the door body 22 closes the storage compartment 211, the front surface of the door body 22 is flush with the front surface of the cabinet 1.

[0056] In another embodiment, reference Figure 6a-6c By adjusting the connection position between the hinge 3 and the cabinet 1 and the door body 22, when the door body 22 closes the storage compartment 211, the front surface of the door body 22 and the front surface of the cabinet 1 are on the same plane. However, compared with the aforementioned connection method, the connection position between the hinge 3 and the cabinet and the box body in this embodiment is different.

[0057] Specific to Figure 6b In the embodiment, one of the planar portion 311 of the first hinge leaf and the planar portion 321 of the second hinge leaf is connected to the front surface of the door body 22, and the other is connected to the front surface of the cabinet 1, and the hinge pin 33 is located between the door body 22 and the cabinet 1.

[0058] It can be understood that through such a configuration, when the door body 22 is pivoted relative to the cabinet 1, the opening angle thereof can be greater than 90°, or even reach 180°. The effect achieved can, on the one hand, facilitate the user to take food from the storage compartment 211. On the other hand, when a drawer is arranged in the storage compartment 211, the pulling out of the drawer is not interfered by the door body.

[0059] In the present invention, when the refrigerator body 21 is installed in the installation cavity of the cabinet 1, it can be arranged in a tightly embedded manner, so that the position of the box body 21 in the installation cavity of the cabinet 1 can be ensured to be relatively fixed, and there will be no deviation when the door body 22 is pivotally connected to the cabinet 1 to close the storage compartment 211.

[0060] However, when the box body 21 is closely embedded in the installation cavity, installation is difficult. Figure 7-10 As shown, optionally, the embedded device may further include a first stopper 4 disposed at the rear side of the box 21 to limit the box in the front-to-back direction. During the installation process, the thickness of the first stopper 4 is preset, and it is disposed at the rear side of the box 21, and then the box 21 is pushed into the installation cavity. When pushed to the limit position, the position of the box 21 in the front-to-back direction is also fixed.

[0061] Specifically, refer to Figure 8 The first limiting member 4 includes a plurality of limiting columns 41 and a connecting rod 42 arranged along the vertical direction. The plurality of limiting columns 41 are distributed along the left-right direction. The connecting rod 42 connects any two adjacent limiting columns 41. The limiting columns 41 are mainly used to limit the front and rear positions of the box body 21.

[0062] Preferably, a plurality of support members 43 are arranged from top to bottom on the two limit columns 41 located on both sides in the left-right direction. The support members 43 are arranged on the side of the limit columns 41 opposite to the connecting rod 42. The support rod 43 is usually arranged to be elastic. When the first limit member 4 is pushed into the installation cavity, the end face position of the support rod 43 can be adjusted in the left-right direction to ensure that it abuts against the left and right side walls of the installation cavity to prevent it from shaking relative to the cabinet 1 and affecting the position of the box body 21.

[0063] Furthermore, if Fig. 9 As shown in Figure 10, the embedded refrigeration device also includes a second limiting member 5 arranged on at least one of the left and right side walls of the box body 21 to limit the box body in the left and right directions.

[0064] Specifically, refer to Fig.10The second limiting member includes a plurality of wedge-shaped limiting pads 51 arranged from top to bottom, the wedge-shaped limiting pads having a mounting surface 511 connected to the side wall and a limiting surface 512 parallel to the mounting surface, the rear side of the limiting surface extending toward the rear side of the box body 21 and intersecting with the mounting surface 511 to form a guiding inclined surface 513. When the box body 21 is pushed into the mounting cavity of the cabinet 1, the guiding inclined surface 513 plays a certain guiding role, and finally makes the abutting surface 512 abut against the side wall of the box body 21.

[0065] With this arrangement, on the one hand, during the installation of the box body 21, since there is a certain gap between the box body 21 and the wall of the installation cavity of the cabinet 1, the installation is easier; on the other hand, the abutment surface 512 abuts against the side wall of the box body 21 and can limit the position of the box body in the installation cavity.

[0066] Furthermore, the wedge-shaped limiting pad 51 is provided with an elastic layer and a hard smooth layer in sequence in a direction perpendicular to the mounting surface 511 and away from the side wall. The elastic layer can be retracted to better limit the wedge-shaped limiting pad 51 between the cabinet 1 and the box body 21, and the hard smooth layer generates less friction resistance when the box body 21 is pushed into the mounting cavity, making the installation more labor-saving.

[0067] Optionally, the wedge-shaped limiting pads 51 are disposed on both the left and right side walls of the box body 21, and the number of the wedge-shaped limiting pads on each side wall is set to two, one of the two wedge-shaped limiting pads 51 is located at the upper section of the side wall and close to the front side of the box body 21, and the other is located at the lower section of the side wall and close to the front side of the box body 21. When arranged in this way, a better stabilization effect can be achieved.

[0068] In summary, the embodiments of the present invention achieve the following technical effects:

[0069] The door body 22 is directly connected to the cabinet 1 through an ordinary single-axis rotating hinge or a folding hinge, which avoids the interference of the corners of the door body 22 with the cabinet 1 when it is opened, thereby ensuring that the opening angle of the door body is greater than or equal to 90°. The prices of single-axis rotating hinges and folding hinges are generally lower than those of double-axis rotating hinges. Such an arrangement can reduce the cost of refrigerator manufacturing.
