When the quick cooling device 100 needs to be opened, the operating handle 343 is toggled or pressed by hand along the compression direction of the elastic member 341, the elastic member 341 is compressed by force, the stop lever 3421 is separated from the limit of the stop hole 321, and the locking switch 34 is opened; when the quick cooling device 100 needs to be closed, the first housing 31 is pushed to rotate towards the closed position or the operating handle 343 is pulled towards the closed position, the chamfer at the top end of the blocking rod 3421 moves towards the second housing 32 under the pushing action of the elastic member 341, when the top end of the blocking rod 3421 enters the stopping hole 321 of the second housing 32, the blocking rod 3421 is normally stopped in the stopping hole 321 under the elastic force action of the elastic member 341, so that the quick cooling device 100 is closed, the blocking rod 3421 cannot be disengaged under the limit of the stopping hole 321, the quick cooling device 100 cannot be mistakenly operated and opened under the interference of the external acting force, the to-be-cooled device 300 falls off, and the reliability of the closed state of the locking switch 34 is ensured.

In addition, the locking switch 34 can also provide a certain pretightening force for the first casing 31 and the second casing 32, so that the inner walls of the first casing 31 and the second casing 32 are tightly attached to the outer wall of the to-be-cooled member 300, thereby minimizing the gap between the two, ensuring that the rapid cooling device 100 is in the optimal heat exchange state, and improving the cooling and heat exchange efficiency of the rapid cooling device 100.

Further, the side walls of the first receiving groove a1 and the side walls of the second receiving groove a2 are both arc-shaped, and at least one of the first housing 31 and the second housing 32 has a support tray 322 extended into the receiving cavity a. In this way, not only the side walls of the accommodating grooves of the first housing 31 and the second housing 32 are designed to be conformal, so that the cold storage component 3 can be more stably and reliably fixed to the to-be-cooled member 300, but also the to-be-cooled member 300 can be supported by the supporting tray 322, so that the to-be-cooled member 300 can be more firmly fixed in the accommodating cavity a.

The refrigerator according to the embodiment of the second aspect of the present invention includes the quick cooling device 100 as in any one of the above embodiments.

Wherein, be equipped with linking bridge 400 on the refrigerator door 200, linking bridge 400 fixed mounting is in the inboard of refrigerator door 200, and rapid cooling device 100 can be pegged graft or the joint is on linking bridge 400 through fixing base couple 14 and safety cover couple 53 to fix rapid cooling device 100 in the inboard of refrigerator door 200.

Therefore, according to the refrigerator of the embodiment of the present invention, the rapid cooling of the to-be-cooled member 300 can be realized by the rapid cooling device 100, so that the functions of the refrigerator are more diversified, and further, market demands are more satisfied, so as to improve market competitiveness of the refrigerator having the rapid cooling device 100 of the embodiment of the present invention.

Next, the operation of the instant cooling apparatus 100 according to the embodiment of the present invention will be described with reference to fig. 1, 13, 14 and 15.

The quick cooling device 100 includes: fixing base 1, driver part 2, cold-storage part 3, movable support 4 and safety cover 5, wherein, the fixed whole fast cold charge of fixing base 1 is put 100, driver part 2 comprises drive mechanism 22 and rotating electrical machines 21, drive mechanism 22's driven gear 222 passes the shaft hole b and the movable support 4 fixed connection of fixing base 1, and then when rotating electrical machines 21 rotated, driven gear 222 drove movable support 4 and rotates or swing, in order to realize fast cold charge's 100 intensive heat transfer, treat rapidly that cooling part 300 cools down, the cooling.

As shown in fig. 1, when the rapid cooling device 100 is at the stop position, the cold storage component 3 can be taken out of the refrigerator or the entire rapid cooling device 100 can be taken down, the operating handle 343 is pressed to open the locking switch 34, and the to-be-cooled piece 300 is placed in the accommodating cavity a, so that the rapid cooling device 100 is plugged onto the connecting bracket 400, or the cold storage component 3 is fixed onto the clamping groove 411 of the movable support 4.

Further, the driving part 2 is electrically operated, and the rotating electric machine 21 drives the movable support 4 and the cold storage part 3 to swing (see fig. 13 and 14), or the rotating electric machine 21 drives the movable support 4 and the cold storage part 3 to rotate (see fig. 15). Therefore, the contact between the cold storage member 300 to be cooled and the cold storage agent in the cold storage member 3 is more sufficient through the rotating or swinging cold storage member 3, and the mixing between the cold storage agents is more sufficient, so that the heat exchange between the cold storage agent and the cold storage member 300 to be cooled is enhanced, and the refrigerating speed of the quick cooling device 100 is increased.

It should be noted that, in fig. 13, the movable support 4 swings leftwards relative to the fixed base 1, in fig. 14, the movable support 4 swings rightwards relative to the fixed base 1, in fig. 15, the movable support 4 rotates relative to the fixed base 1, and the dashed line part is the movement track of the movable support 4.

Further, after the rapid cooling device 100 finishes cooling the object 300 to be cooled, the operating handle 343 is pulled to make the blocking rod 3421 come out of the blocking hole 321, so as to unlock the locking switch 34, and the object 300 to be cooled can be taken out.
