Abstract

A refrigerator with a switchable hinge assembly which includes a cabinet ( 10 ), a door ( 20 ) and the hinge assembly ( 30 ) for connecting the cabinet ( 10 ) and the door ( 20 ), wherein the hinge assembly ( 30 ) includes a plurality of hinge parts ( 31,32 ), and a switching assembly ( 40 ); when the door ( 20 ) is in an opening process, the switching assembly ( 40 ) controls the plurality of hinge parts ( 31,32 ) to successively operate in a first sequence, and when the door ( 20 ) is in a closing process, the switching assembly ( 40 ) controls the plurality of hinge parts ( 31,32 ) to successively operate in a second sequence, and the first sequence is opposite to the second sequence. An opening-closing freedom degree of the door ( 20 ) may be increased by the refrigerator with the switchable hinge assembly, and various motion tracks may be generated to adapt to different application scenarios.

First claim

What is claimed is:

1. A refrigerator with a switchable hinge assembly, comprising: a cabinet, a door for opening and closing the cabinet, and the hinge assembly for connecting the cabinet and the door, wherein the hinge assembly comprises a plurality of hinge parts, and a switching assembly; when the door is in an opening process, the switching assembly controls the plurality of hinge parts to successively operate in a first sequence, and when the door is in a closing process, the switching assembly controls the plurality of hinge parts to successively operate in a second sequence, and the first sequence is opposite to the second sequence;
the hinge assembly comprises a first hinge part and a second hinge part, the switching assembly is connected with the first hinge part and the second hinge part, the first hinge part is fixed to the cabinet, and the second hinge part is fixed to the door; when the door is in the opening process, the switching assembly moves relative to the first hinge part first, and then, the second hinge part moves relative to the switching assembly; when the door is in the closing process, the second hinge part moves relative to the switching assembly first, and then, the switching assembly moves relative to the first hinge part; the switching assembly comprises a first fitting part and a second fitting part; when the door is opened from a closed state to a first opening angle, the first hinge part and the first fitting part move relatively, and the second fitting part limits the second hinge part; when the door is continuously opened from the first opening angle to a second opening angle, the second hinge part is released from limit of the second fitting part, and relative movement between the first fitting part and the first hinge part is limited; when the door is continuously opened from the second opening angle to a maximum opening angle, the second hinge part and the second fitting part move relatively; the first hinge part and the first fitting part move relatively by a first shaft set and a first groove set which are fitted with each other, and the second hinge part and the second fitting part move relatively by a second shaft set and a second groove set which are fitted with each other;
wherein the first shaft set comprises a first shaft and a second shaft, the first groove set comprises a first groove fitted with the first shaft and a second groove fitted with the second shaft, the second shaft set comprises a third shaft and a fourth shaft, and the second groove set comprises a third groove fitted with the third shaft and a fourth groove fitted with the fourth shaft.

2. The refrigerator with a switchable hinge assembly according to claim 1 , wherein the cabinet comprises an accommodating chamber and a pivoting side connected with the hinge assembly, and when the door is in the opening process, the hinge assembly at least drives the door to move from the pivoting side towards the accommodating chamber.

3. The refrigerator with a switchable hinge assembly according to claim 1 , wherein the switching assembly comprises a first switching part having the first fitting part disposed therein and a second switching part having the second fitting part disposed therein, the first and second switching parts are fitted with each other; when the door is opened from the closed state to the first opening angle or continuously opened from the second opening angle to the maximum opening angle, the first switching part and the second switching part are relatively stationary, and when the door is continuously opened from the first opening angle to the second opening angle, the first switching part moves relative to the second switching part, such that the second hinge part is released from the limit of the second fitting part, and the relative movement between the first fitting part and the first hinge part is limited.

4. The refrigerator with a switchable hinge assembly according to claim 3 , wherein the first switching part comprises a first lining, a first sliding sheet and a first bushing which are stacked sequentially, and the second switching part comprises a second lining, a second sliding sheet and a second bushing which are stacked sequentially; the first lining, the first bushing, the second lining and the second bushing are made of plastic, and the first sliding sheet and the second sliding sheet are made of metal.

5. The refrigerator with a switchable hinge assembly according to claim 4 , wherein the first switching part further comprises a first decorative sheet covering peripheries of the first lining, the first sliding sheet, and the first bushing, the second switching part further comprises a second decorative sheet covering peripheries of the second lining, the second sliding sheet, and the second bushing, and the first decorative sheet and the second decorative sheet are separated from each other.

6. The refrigerator with a switchable hinge assembly according to claim 1 , wherein the first hinge part comprises the first shaft and the second shaft, the first fitting part comprises the first groove and the second groove, the second fitting part comprises the third shaft and the fourth shaft, and the second hinge part comprises the third groove and the fourth groove.

7. The refrigerator with a switchable hinge assembly according to claim 6 , wherein the first groove comprises a first upper groove located at the first switching part and a first lower groove located at the second switching part, the first upper groove comprises a first upper free section, and the first lower groove comprises a first lower free section; the second groove comprises a second upper groove located at the first switching part and a second lower groove located at the second switching part, the second upper groove comprises a second upper free section, the second lower groove comprises a second lower free section, the third groove comprises a third free section, the fourth groove comprises a fourth free section, the first groove set comprises a locking section, and the second groove set comprises a limiting section; when the door is opened from the closed state to the first opening angle, the first switching part and the second switching part are relatively stationary, the first upper free section and the first lower free section are overlapped to form a first free section, the second upper free section and the second lower free section are overlapped to form a second free section, the first shaft is at the first free section, and the switching assembly moves relatively to the first shaft, the second shaft is at the second free section, and the switching assembly moves relatively to the second shaft, and the third shaft and/or the fourth shaft are/is limited at the limiting section, such that the switching assembly limits the second hinge part; when the door is continuously opened from the first opening angle to the second opening angle, the first switching part and the second switching part move relatively, such that the second hinge part is released from the limit of the switching assembly, and the first shaft and/or the second shaft stay/stays at the locking section, such that the switching assembly is limited against the first hinge part; when the door is continuously opened from the second opening angle to the maximum opening angle, the third shaft moves at the third free section, and the fourth shaft moves at the fourth free section.
