This is beneficial to preventing an end wall of the receiving hole123from bearing stress and being damaged because of being in direct contact with an end portion of the columnar portion153.

In a preferable example, sizes of the columnar portion153and the receiving hole123in an axial direction (parallel to the direction z) may be adjusted to form the interval between the upper end153aof the columnar portion153and the top wall123aof the receiving hole123.

In one or more embodiments, the second connection portion151may be board-shaped and connected to a bottom surface of the first door120. This is beneficial to ensuring an aesthetic appearance of the refrigeration device100while enlarging a stress surface of the second hinge member150.

In one or more embodiments, the second hinge member150may further be fixed on the top of the first door120(for example, a position of the region B inFIG.2). This is beneficial to positioning the first door120and the second door130above, and is beneficial to reducing a possibility of damage of an upper door frame member of the first door120as well.

In one or more embodiments, still referring toFIG.4, the columnar portion153and the second connection portion151may be integrally formed. This is beneficial to positioning the first door120and the second door130, and is beneficial to improving entire firmness of the second hinge member150, thus preventing the second hinge member150from compressing and deforming and even breaking when the first hinge member140supports the first door120via the second hinge member150.

Specifically, the second hinge member150is fixed on the bottom of the first door120. The first hinge member140is matched with the second hinge member150when supporting the first door120, thus preventing the first hinge member140from being directly abutted against a plastic door frame of the first door120, thus being beneficial to preventing damage of a door frame member of the first door120.

For example, the columnar portion153and the second connection portion151may be integrally formed through casting.

In one or more embodiments, the second hinged portion152may be integrally formed through casting with the columnar portion153and the second connection portion151as well.

Preferably, the adjustment member170may be located in the shaft sleeve160.

Specifically, a plurality of steps may be respectively disposed relatively on the adjustment member170and the first hinge shaft143. Through pairing of steps on butting end surfaces of the adjustment member170and the first hinge shaft143, a distance between the shaft sleeve160and the first hinged portion142can be adjusted in the direction z, thus adjusting a height position of the first door120relative to the main body110in the direction z.

For example, through pairing of the steps on the butting end surfaces of the adjustment member170and the first hinge shaft143, the second hinge member150and the first door120may be raised along the direction z (or lowered along a reverse direction of the direction z), to ensure that the first door120can effectively close the storage compartment111of the main body110.

In one or more alternative embodiments, referring toFIG.4,FIG.8, andFIG.9, the second hinged portion152may include a second shaft hole156. The second door130may include a second hinge shaft131. The second hinge shaft131is rotatably located in the second shaft hole156. In this way, the second door130can rotate around the second hinge shaft131, to open or close the opening121.

Specifically, the second hinge shaft131may be coupled to a door opener132installed in the second door130, to reduce a quantity of parts, facilitate installation, and improve integration. The door opener132may include a fixing arm133. A length direction of the fixing arm133is parallel to the direction z. The fixing arm133extends into the second door130, so that connection between the second door130and the main body110is more stable.

In one or more embodiments, still referring toFIG.1andFIG.10, the first door120and the second door130may be respectively provided with a slot body125, and the slot bodies125of the first door120and the second door130are spliced, that is connected, to form a space accommodating the second hinge member150. In this way, when the second door130closes the opening121of the first door120, the second hinge member150may be at least partially hidden. To be specific, a plane formed by the second hinge member150in the direction x and the direction y and a lower surface of the first door120and the second door130are in a same plane, thus implementing a hidden design of the second hinge member150, and being beneficial to optimizing entire beauty of the refrigeration device.

In a non-limiting embodiment, still referring toFIG.11, there is a gap between top surfaces and/or bottom surfaces of the second hinge member150and the second door130, to be beneficial to rotation of the second door130around the second hinge shaft131.

Further, the second hinge member150is connected to a top surface and/or a bottom surface of the first door120, to further disperse stress on the receiving hole123to the first door120via the second hinge member150, to better prevent the first door120(for example, the plastic door frame of the first door120) from being damaged.

The lower side of the second hinge member150is a side, in contact with the first hinge member140, of the second hinge member150(namely, a side away from the first door120and the second door130in the direction z).

In a non-limiting embodiment, when the first door120rotates to a first preset angle (for example, rotates to a position shown inFIG.12), the first stop portion157may be abutted against the first limiting portion144. Continuous rotation of the first door120(or the first door120and the second door130) after rotation to the first preset angle is limited, to prevent damage of the door body caused by an excessively large rotation angle of the first door120(or the first door120and the second door130).

In one or more embodiments, the second door130and the first door120are pivotably disposed on the front side of the main body110by using hinged parts. The hinged parts may include the first hinge member140, the second hinge member150, and the door opener132fixed on the second door130. Through mating between the first hinge member140, the second hinge member150, and the door opener132, an opening and closing function of the first door120and/or the second door130is implemented.

In one or more embodiments, referring toFIG.6toFIG.9, the second hinge member150may include a second limiting portion158, the second door130is provided with a second stop portion134that is matched with the second limiting position158, and when the second door130rotates to a second preset angle (for example, rotates to a position shown inFIG.13), the second stop portion134is abutted against the second limiting portion158.

Different from the refrigeration device100shown inFIG.1toFIG.13, only one door body may be disposed on a front side of a main body110of the refrigeration device200in this embodiment.

Specifically, with reference toFIG.14andFIG.15, the refrigeration device200may include: a main body110; a first door120, the first door120being pivotably disposed on a front side of the main body110; a first hinge member140, including a first connection portion141that is fixed on the main body110and a first hinge shaft143that is connected to the first door120; and a connection member210, including a second connection portion151that is connected to the bottom of the first door120and a columnar portion153that extends into the first door120, the first hinge shaft143extending into the columnar portion153, and the first door120being supported on the first hinge member140via the connection member (210).

It is understood by a person skilled in the art that in the technical solution of this embodiment of the present invention, through the design of the connection member210, while the main body110is hinged to the first door120, a lower frame member (for example, a lower door frame member122shown inFIG.1toFIG.13) of the first door120can be effectively prevented from being damaged because of being in direct contact with the first hinge member140, thus improving reliability of a door (namely, the first door120) of the refrigeration device200.

In a non-limiting embodiment, the refrigeration device200may include a second door130as well, and the second door130is pivotably disposed on a front side of the first door120, to form the refrigeration device100shown inFIG.1toFIG.13.

Further, the connection member210may be the second hinge member150inFIG.1toFIG.13. The second hinge member150includes the second hinged portion152hinged to the second door130. It is understood by a person skilled in the art that based on the design of this embodiment of the present invention, when the first hinge member140supports the first door120, a stress surface includes the second hinge member150(namely, the connection member210), so that a hinge hole (namely, the receiving hole123inFIG.1toFIG.13) on the first door120that is for hinging to the first hinge member140can be effectively prevented from being damaged due to excessive large borne stress. Further, the connection member210may further precisely position the first door120and the second door130, thus improving assembly precision of a door body.

Further, with reference toFIG.1toFIG.15, the first door120may include a lower door frame member122, the lower door frame member122may have a receiving hole123recessed toward the interior of the first door120, the columnar portion153extends into the receiving hole123, and there is an interval between an upper end153aof the columnar portion153and a top wall123aof the receiving hole123, to prevent the first door120from being in direct contact with the columnar portion153, and more effectively prevent the hinge hole on the first door120that is for hinging to the first hinge member140from being damaged due to excessive large borne stress.

More specifically, for explanations of the nouns in the embodiments, reference may be made to related descriptions inFIG.1toFIG.13. Details are not described herein again. The present invention is disclosed as above, but the present invention is not limited thereto. Any person skilled in the art may vary or modify the present invention, without departing from the spirit or scope of the present invention. Therefore, the protection scope of the present invention is defined by the claims.
