[0046] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0047] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In addition, the terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0048] An embodiment of the present invention provides a refrigeration device, the refrigeration device includes a box body that can be embedded in an external environment part, the external environment part can be, for example, a decorative part, the refrigeration device can be a refrigerator, or can be any other household appliance embedded in the external environment part. The household appliance can be other household appliances other than a refrigerator, or furniture such as a storage cabinet, so that the household appliance equipped with the refrigeration device can achieve the technical effect of being embedded in other decorative or external environment parts.

[0049] In this embodiment, Figures 1 to 4 As shown, the refrigeration device comprises a box body 1 having a refrigeration compartment, a door body 2 and a hinge assembly 3, wherein the door body 2 is pivoted on the box body 1 through the hinge assembly 3 to open or close the refrigeration compartment;

[0050] In this embodiment, the box body 1 has a box front wall 11 and a box side wall 12 arranged perpendicular to the box front wall 11. In this embodiment, the box front wall 11 and the box side wall 12 are generally planar. The opening of the refrigerating compartment is arranged on the box front wall 11, and the door body 2 is located at the front side of the box body 1 as a whole, and when the door body 2 is in a closed state, the refrigerating compartment opening is closed. It should be noted that the front side here is the opening direction of the refrigerating compartment.

[0051] like Figure 1-5 As shown, the door body 2 also has a door front wall 21, a door side wall 22 and a door top wall 23. The intersection of the door front wall 21 and the door side wall 22 forms a door outer edge. When the door body 2 is in a closed state, that is, when the door body 2 covers the opening of the refrigeration compartment, the door front wall 21 is arranged on the side of the door body 2 away from the box front wall. In this embodiment, the door front wall 21 is flat as a whole, and is roughly parallel to the box front wall 11 when the door body 2 is in a closed state.

[0052] In this embodiment, the door front wall 21 and the door side wall 22 are both roughly planar. When the door body 2 is in a closed state, the door front wall 21 is parallel to the box front wall 11, and the plane where the door side wall 22 is located is parallel to the plane where the box side wall 12 is located.

[0053] In this embodiment, Figure 1-4 As shown, the hinge assembly 3 includes a rotating shaft 31 and a base 32 matched with the rotating shaft 31; the rotating shaft 31 rotates on the base 32, the rotating shaft 31 is fixed on the box body 1, and the base 32 is fixed on the door body 2.

[0054] The door body 2 is provided with a base mounting groove 25 adapted to the base 32, and the base mounting groove 25 has a mounting groove lateral opening 251 provided on the door side wall 22. The base 32 is positioned in the mounting groove 25 from the mounting groove lateral opening 251, and the position of the base 32 in the mounting groove 25 can be adjusted along the direction of the mounting groove lateral opening 251.

[0055] The base 32 is installed and positioned in the mounting groove 25 from the lateral opening 251 of the mounting groove, and the position of the base 32 can be adjusted in the mounting groove 25. The base 32 can be adjusted along the setting direction of the lateral opening 251 of the mounting groove. The movement and adjustment of the base 32 actually means that the installation position on the door body 2 can be adjusted, so that after the door body 2 is installed and fixed, the position of the door body 2 relative to the rotating shaft 31 can be adjusted by moving the base 32, thereby conveniently realizing the adjustment of the door body 2.

[0056] Specifically, Figure 4-5 As shown, the base mounting groove 25 has a mounting groove bottom 252, and the mounting groove bottom 252 is opposite to the mounting groove lateral opening 251; the hinge assembly 3 also has a fastener 33 fixed to the mounting groove bottom 252; the fastener 33 presses and fixes the base 32 to the mounting groove bottom 252;

[0057] like Figure 1-4 As shown, the hinge assembly 3 further comprises an elastic member 34 located between the installation groove bottom 252 and the base 32 ; the installation depth of the fastener 33 at the installation groove bottom 252 is adjustable.

[0058] During the movement and adjustment process, the base 32 actually adjusts the distance from the bottom 252 of the mounting groove. When the installation depth of the fastener 33 at the bottom 252 of the mounting groove is large, it means that the force exerted by the fastener 33 on the base 32 is large, driving the base 32 to move in a direction close to the bottom 252 of the mounting groove. The elastic member 34 is compressed and deformed under the action of the base 32 and accumulates rebound force.

[0059] When the installation depth of the fastener 33 at the bottom 252 of the mounting groove decreases, it indicates that the force exerted by the fastener 33 on the base 32 is weakened, and under the action of the elastic member 34, the base 32 moves in a direction away from the bottom 252 of the mounting groove, so as to realize the movement of the base 32 in the direction of the lateral opening 251 of the mounting groove.

[0060] In the above embodiment, the position of the base 32 in the installation groove 25 is adjusted by adjusting the installation depth of the fastener 33, thereby adjusting the installation position of the door body 2 on the box body 1. The structure is simple and the operation is convenient.

[0061] In this embodiment, if Figure 7As shown, the fastener 33 includes a bolt body 331, and the door body 2 has a threaded hole 221 arranged at the bottom of the installation groove 252 and threadedly matched with the bolt body 331; the axial direction of the bolt body 331 is parallel to the direction of the lateral opening 251 of the installation groove; the base 32 is provided with a through hole adapted to the bolt body 331;

[0062] The fastener 33 further includes a nut 332 disposed at an end of the bolt body 331 away from the installation groove bottom 252 , and the nut 332 is pressed tightly against the base 32 .

[0063] The elastic member 34 is sleeved outside the bolt body 331 ; the elastic member 34 may be a compression spring sleeved outside the bolt body 331 .

[0064] The base 32 also has an elastic member positioning groove 323 adapted to the elastic member 34 , and the elastic member positioning groove 323 is located at the edge of the perforation. The setting of the elastic member positioning groove 323 can more conveniently realize the installation and fixation of the elastic member 34 .

[0065] like Fig.10 As shown, the base 32 is provided with a guide column 324 on one side facing the mounting groove bottom 252, and the door body 2 is provided with a guide hole 222 adapted to the guide column 324, and the guide hole 222 is recessed from the mounting groove bottom 252 toward a direction away from the mounting groove lateral opening 251. The guide hole 222 is provided in the mounting groove 25 and has an inlet located at the mounting groove bottom 252.

[0066] The cooperation between the guide hole 222 and the guide column 324 can more stably realize the movement and adjustment of the base 32 .

[0067] In the first embodiment, if Figure 1-2 As shown, the base 32 has a slot body 325 adapted to the rotating shaft 31, and the opening direction of the slot body 325 is perpendicular to the direction of the lateral opening 251 of the mounting slot;

[0068] The base installation slot 25 further has a mounting slot top opening 253 that is opened toward the door top wall 23 , and the slot body 325 is exposed outward from the mounting slot top opening 253 .

[0069] In the above embodiment, the opening direction of the groove body 325 of the base 32 faces the axial direction of the rotating shaft 31. During the installation and fixing process, the base 32 is first sleeved on the rotating shaft 31, and then the door body 2 and the base 32 are connected and fixed.

[0070] In the second implementation, if Figure 3-6As shown, the base 32 includes a support block 322 and a limit block 321 matched with the support block 322. The support block 322 and the limit block 321 are arranged along the opening direction of the mounting slot lateral opening 251 of the base mounting slot 25, and the support block 322 is located closer to the base mounting slot 25 relative to the limit block 321.

[0071] The support block 322 is provided with a rotation groove 3220 that matches the rotation shaft 31. The rotation shaft 31 rotates in the rotation groove 3220. The rotation groove 3220 has a rotation groove radial opening 3221 and a rotation groove axial opening 3222.

[0072] The radial opening 3221 of the rotating groove is opened along the radial direction of the rotating shaft 31, and the axial opening 3222 of the rotating groove is opened along the axial direction of the rotating shaft 31. The rotating groove 3220 is exposed outwardly from the radial opening 3221 of the rotating groove; the rotating shaft 31 can be detached from the rotating groove 3220 from the radial opening 3221 of the rotating groove; after the support block 322 is installed and fixed in the base mounting groove 25, the opening direction of the radial opening 3221 of the rotating groove is toward the lateral opening 251 of the mounting groove.

[0073] The limiting block 321 is used to limit the rotation shaft 31 from being separated from the radial opening 3221 of the rotation slot; the rotation shaft 31 rotates in the rotation slot and is located between the limiting block 321 and the supporting block 322 .

[0074] In this embodiment, the base 32 of the hinge assembly 3 is divided into two parts: a support block 322 and a limit block 321. A rotation groove 3220 adapted to the rotating shaft is arranged on the support block 322. The rotation groove 3220 has a rotation groove radial opening 3221 arranged along the radial direction of the rotating shaft 31, so that the rotating shaft 31 can be disengaged from the rotation groove 3220 along the radial direction, thereby facilitating the assembly of the rotating shaft 31 in the rotation groove 3220. The positioning of the rotating shaft 31 in the rotation groove 3220 is achieved by the limit block 321, so that the rotation of the rotating shaft 31 in the rotation groove 3220 is stably supported.

[0075] The hinge assembly 3 provided in this embodiment enables the rotating shaft 31 to be installed without being installed in the axial direction of the rotating groove 3220 on the base 32 when assembled with the base 32. The rotating shaft 31 is freed from the restriction of the opening direction of the rotating groove 3220 during assembly, making the assembly of the rotating shaft 31 and the base 32 more convenient.

[0076] In this embodiment, the fastener 33 presses and fixes the limit block 321 on the support block 322;

[0077] The fastener 33 includes a bolt body 331, the support block 322 is provided with a support block through hole 3224 adapted to the bolt body 331, the limit block 321 is provided with a limit block through hole 3213 adapted to the bolt body 331, and the fastener 33 has a nut 332 for tightening against the limit block 321, and the nut 332 is tightened against the edge of the limit block through hole 3213.

[0078] The limit block 321 also has a nut base mounting groove, which is located at the edge of the limit block through hole 3213 and is used to adapt to the nut 332. The setting of the nut base mounting groove can prevent the fastener 33 from protruding out of the surface of the limit block 321 after being installed and fixed.

[0079] In this embodiment, the limiting block 321 is pressed and fixed on the supporting block 322 by the fastener 33 , and the fastener 33 may not be connected to the supporting block 322 .

[0080] When the hinge assembly 3 is mounted and fixed on the refrigerator, the end of the fastener 33 away from the nut 332 is threadedly connected to the door body 2. The fastener 33 presses and fixes the limit block 321 and the support block 322 on the door body 2.

[0081] In the present invention, Fig. 9 As shown, the limit block 321 has an abutting portion 3211 for abutting against the rotating shaft 31 and a mounting portion 3212 for fixing and fitting with the supporting block 322;

[0082] After the limiting block 321 is installed and fixed, the abutting portion 3211 is positioned opposite to the radial opening 3221 of the rotation groove or the abutting portion 3211 extends from the radial opening 3221 of the rotation groove into the rotation groove 3220 .

[0083] The stop block 321 abuts against the rotating shaft 31 to prevent the rotating shaft from shaking in the rotating groove 3220, thereby enabling the door body 2 to be opened more smoothly. After the door body 2 is installed and fixed, the stop block 321 closes the radial opening 3221 of the rotating groove after the abutment portion 3211 is installed and fixed, thereby preventing the rotating shaft 31 from coming out of the radial opening 3221 of the rotating groove.

[0084] In one embodiment, if Fig. 9As shown, in order to better realize the rotation of the rotating shaft 31, the abutment portion 3211 is adapted to the outer wall of the rotating shaft 31; the limiting block 321 is provided with a limiting groove 320 adapted to the rotating shaft 31, and the limiting groove 320 has a limiting groove radial opening 3201 opened toward the rotating shaft 31 and a limiting groove axial opening 3202 opened along the axial direction of the rotating shaft 31; the limiting groove radial opening 3201 is opposite to the rotation groove radial opening 3221;

[0085] like Fig. 9 As shown, the limiting block 321 further includes a limiting groove side wall 3203 disposed on the inner wall of the limiting groove 320, the limiting groove side wall 3203 is opposite to the limiting groove radial opening 3201, and the abutment portion 3211 is disposed on the limiting groove side wall 3203. The entire limiting groove side wall 3203 can serve as the abutment portion 3211 to limit the rotation shaft 31 when the rotation shaft 31 rotates.

[0086] like Figure 8 As shown, the rotating groove 3220 has a rotating groove inner wall 3223, the rotating groove inner wall 3223 is opposite to the rotating groove radial opening 3221, the cross section of the rotating groove inner wall 3223 is arc-shaped as a whole, and the degree of the arc center angle corresponding to the arc is not greater than 90°;

[0087] The above embodiment actually requires that the opening size of the radial opening 3221 of the rotating groove be smaller than the diameter of the rotating shaft 31, so that the rotating shaft 31 can be conveniently positioned in the rotating groove 3220. When the arc center angle of the arc of the cross section of the rotating groove inner wall 3223 is less than 90°, it does not affect the rotation of the rotating shaft 31. In principle, the rotating shaft 31 only needs to be supported by three points in the circumferential direction to achieve stable rotation.

[0088] Correspondingly, the cross section of the limiting groove side wall 3203 is also arc-shaped as a whole, and the degree of the arc center angle corresponding to the arc is not greater than 90°.

[0089] In this embodiment, if Fig. 9 As shown, the cross section of the limiting groove side wall 3203 is semicircular, and the cross section of the rotating groove inner wall 343 is also semicircular, so that a complete circle is formed after the limiting groove 320 and the rotating groove 3220 are connected.

[0090] After the limiting block 321 is installed and fixed, the rotating groove 3220 and the limiting groove 320 are positioned opposite to each other and are spliced ​​into a groove body with a circular cross-section. The groove body is adapted to the rotating shaft 31, and the rotating shaft 31 can rotate circumferentially in the groove body.

[0091] In the above embodiment, a limiting groove 320 adapted to the rotating shaft 31 is actually provided on the limiting block 321 to better achieve the fit with the rotating shaft 31, and the mounting portion 3212 is correspondingly formed beside the limiting groove 320. The side of the mounting portion 3212 facing the door side wall 22 can be directly fitted on the supporting block 322. The fastener 33 is used to press and fix the fitted supporting block 322 and the limiting block 321 on the mounting groove bottom 252 of the door body 2.

[0092] The limiting block 321 is also positioned in the base installation groove 25 after being fixedly fitted with the supporting block 322 , and after the limiting block 321 is positioned, the limiting block 321 does not protrude from the plane where the door side wall 22 is located.

[0093] In this embodiment, if Figure 1-5 As shown, the support block 322 is installed and fixed on the door body 2 from the door side wall 22; the mounting portion 3212 is installed and fixed in the direction of the door side wall 22 and pressed and fixed on the support block 322, and the support block 322 is clamped between the door body 2 and the limit block 321.

[0094] It should be noted that the abutment portion 3211 may have a variety of shapes, and the abutment portion 3211 may be in point contact, line contact, or surface contact with the rotating shaft 31. When in fixed contact or line contact, a corresponding protrusion or a long strip-shaped protrusion may be formed on the limit block 321 to achieve contact with the rotating shaft 31.

[0095] In other embodiments, the stopper 321 may be in the shape of a plate as a whole, the mounting portion 3212 may be in the shape of a flat plate as a whole, the abutting portion 3211 may be in the shape of a curve as a whole, and the stopper groove 320 may be formed by bending the abutting portion 3211 (not shown). The mounting portion 3212 and the abutting portion 3211 may be formed by bending a plate-shaped sheet metal part as a whole, or the stopper 321 may be formed by integral injection molding.

[0096] In other embodiments, the stopper 321 is in the shape of a flat plate as a whole, and the portion of the stopper 321 used to abut against the shaft 31 only occupies a very small portion of the stopper 321, and the plane where the stopper 321 is located is tangent to the cross-sectional circle of the shaft 31. The plane where the stopper 321 is located is extended along the tangent direction of the cross-sectional circle of the shaft 31.

[0097] Correspondingly, the rotating groove 3220 includes a semicircular portion and an extension portion extending from the semicircular portion toward the door side wall 22, the extension portion has a rectangular cross section as a whole, and the semicircular portion has a semicircular cross section as a whole. The extension portion extends in the direction of the rotating groove 3220 opening and has a length not less than the radius of the rotating shaft.

[0098] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention.
