Abstract

An installation device for a built-in refrigerator, comprising: a fixing frame, provided on a bottom plate of a refrigerator in a front-back extension direction of the refrigerator; and at least one guide block, disposed on the fixing frame, the bottom of the guide block being provided with a groove parallel to the front-back extension direction of the refrigerator, and the groove being configured to match a guide rail portion pre-installed on the ground where an installation space is located, to limit the refrigerator to move in the front-back direction, so that the refrigerator can move backward along a preset path to reach an installation position.

First claim

The invention claimed is:

1. An installation device for a built-in refrigerator, used for installing the refrigerator into an installation space in a cabinet, the installation device comprising:
a fixing frame, disposed on a bottom plate of the refrigerator in a front-back extension direction of the refrigerator; and
a plurality of guide blocks, disposed at intervals along the fixing frame, wherein a bottom of each of the plurality of guide blocks is provided with a groove parallel to the front-back extension direction of the refrigerator, and the groove of at least one of the plurality of guide blocks is configured to match a guide rail portion pre-installed on the ground where the installation space is located, to limit the refrigerator to move in the front-back extension direction,
wherein the plurality of guide blocks comprises a first guide block located at a back end of the fixing frame, and
wherein a back portion of the first guide block is formed with a bell mouth expanding backward from a lateral side wall of the groove, the bell mouth being configured to be assembled with one side of the guide rail portion that faces an outside of the installation space, to guide the refrigerator into the guide rail portion.

2. The installation device according to claim 1 , further comprising:
a plurality of leveling feet disposed at a bottom of the refrigerator, located in front of a front bottom pulley of the refrigerator, and configured to level the refrigerator by adjusting a height thereof.

3. A built-in refrigerator, comprising:
a box body; and
the installation device according to claim 1 , the installation device being disposed at a bottom of the box body.

4. The installation device according to claim 1 , further comprising:
a plurality of pulley assemblies disposed in the intervals between the plurality of guide blocks and configured to slide along a surface of the guide rail portion to decrease frictional resistance generated when the refrigerator moves.

5. The installation device according to claim 4 , wherein a pulley assembly of the plurality of pulley assemblies comprises:
a plurality of runners sequentially arranged in an extension direction of the groove, wherein an outer peripheral edge of the runners is formed in a shape matching a top end of the guide rail portion; and
a connector having a shaft hole for matching two ends of a central rotating shaft of each runner, so that the central rotating shaft of the plurality of runners is rotatably connected onto the connector.

6. The installation device according to claim 5 , wherein
the connector comprises two connectors respectively on two lateral sides of the plurality of runners, and the pulley assembly further comprises:
a fixing shaft disposed between the two connectors in a penetrating manner; and
a cover housing fixedly connected to two ends of the fixing shaft and configured to limit the plurality of runners in the cover housing, wherein a bottom of the cover housing is provided with an opening to allow the plurality of runners to be in contact with the surface of the guide rail portion.

7. An auxiliary installation assembly for a built-in refrigerator, used for installing the refrigerator into an installation space in a cabinet, the auxiliary installation assembly comprising:
a rail assembly configured to at least be disposed on a lateral side of a ground where the installation space is located, and configured to be disposed in a front-back extension direction of the ground, to allow the refrigerator to get in and out of the installation space in the front-back extension direction, and the rail assembly comprises:
a bottom plate portion, configured to be laid on the ground; and
a guide rail portion formed extending upward from a surface of the bottom plate portion and configured to allow a guide block of the installation device according to claim 1 to move along the surface thereof; and
a limiting portion formed extending upward from the surface of the bottom plate portion and disposed parallel to the guide rail portion at an interval.

8. The auxiliary installation assembly according to claim 7 , wherein
the auxiliary installation assembly further comprises:
a positioning member configured to be disposed on the ground parallel to an extension direction of the rail assembly, and having a positioning strip parallel to the limiting portion, wherein the guide rail portion is located between the positioning strip and the limiting portion, and the positioning member is further configured to match the limiting portion to adjust a moving path of the refrigerator when the guide block deviates from the guide rail portion; and
a pad located between the rail assembly and the positioning member and configured to elevate a back bottom pulley of the refrigerator when the refrigerator moves to an installation position.
