Referring to fig. 1, in one embodiment of the present invention, a refrigeration apparatus 100, such as a refrigerator, is provided for keeping an article at a low temperature and prolonging a storage time of the article.

The refrigeration device 100 comprises a refrigeration cabinet 10 and a cabinet door 30, the refrigeration cabinet 10 has a refrigeration space, and the cabinet door 30 is openably and closably arranged relative to the refrigeration cabinet 10 to close or open the refrigeration space. The refrigerating space is used for storing articles, so that the articles are in a low-temperature environment, and the storage time of the articles can be prolonged. In addition, the cabinet door 30 can be opened and closed, and when articles need to be stored and taken, the cabinet door 30 is opened; when the articles are taken and placed, the cabinet door 30 is closed, and the refrigerating space can be closed, so that the articles are in a sealed low-temperature environment. However, in the using process, after the articles are taken and placed, the cabinet door 30 is not closed tightly, which may further result in wasting the energy consumption of the refrigeration equipment 100.

Referring to fig. 1 to 3, in order to solve the above technical problem, a locking device 50 is added to a refrigeration apparatus 100.

The latch 50 includes a latch mechanism 52 and a mating mechanism 54, one of the latch mechanism 52 and the mating mechanism 54 is disposed on the refrigerated cabinet 10, and the other of the latch mechanism 52 and the mating mechanism 54 is disposed on the cabinet door 30. The latch mechanism 52 is controlled to interact with the mating mechanism 54 and generate a latching force that drives the closure of the cabinet door 30 relative to the refrigerated cabinet 10. When the user does not close the cabinet door 30 tightly, the locking mechanism 52 and the matching mechanism 54 can be matched to apply a locking force to the cabinet door 30, so as to drive the cabinet door 30 to move towards the direction close to the refrigeration cabinet body 10, tightly close the cabinet door 30, seal the refrigeration space, prevent the cabinet door 30 from not being closed and causing waste of energy consumption, and save the power consumption of the refrigeration equipment 100.

The refrigerated space has an opening towards the cabinet door 30, the cabinet door 30 being hinged to the refrigerated cabinet body 10 and opening or closing the opening. In this manner, access to the refrigerated space is provided through the opening, and when the door 30 is moved to completely cover the opening, the refrigerated space is closed. The direction of the locking force is the direction of the cabinet door 30 pointing to the opening, so that the cabinet door 30 is driven to rotate in the direction of covering the opening through the locking force, and the refrigerating space can be closed.

In some embodiments, the cabinet door 30 is hinged to the refrigerated cabinet 10, the latch mechanism 52 is disposed on the refrigerated cabinet 10, and the mating mechanism 54 is disposed on the cabinet door 30; the latch mechanism 52 is controlled to interact with the mating mechanism 54 and pull the door 30 rotationally closed relative to the refrigerated cabinet 10. That is, the latch mechanism 52 engages with the engaging mechanism 54 and pulls the door 30 to rotate around its hinge point with the refrigerated cabinet 10 in a direction close to the refrigerated cabinet 10, so as to close the refrigerated space of the refrigerated cabinet 10.

Further, the engaging mechanism 54 has a buckle, and the latch mechanism 52 includes a driving member 51 and a hook 53, and the hook 53 generates a pulling force to pull the buckle to move closer to the refrigeration cabinet 10 under the action of the driving member 51. The driving member 51 drives the hook 53 to move, the moving hook 53 hooks the buckle and pulls the buckle to move towards the refrigeration cabinet 10, so as to drive the cabinet door 30 to rotate towards the refrigeration cabinet 10, thereby sealing the refrigeration space.

When it is detected that the cabinet door 30 is not closed tightly, the driving member 51 is controlled to move to drive the hook 53 to protrude out of the refrigeration cabinet 10 and contact the buckle on the cabinet door 30. Then, the driving member 51 drives the hook 53 to move around the direction close to the refrigeration cabinet 10, so as to push the buckle buckled with the hook 53 and the cabinet door 30 fixedly connected with the buckle 54 to rotate towards the direction close to the refrigeration cabinet 10, thereby sealing the refrigeration space of the refrigeration cabinet 10 and closing the cabinet door 30.

Specifically, in the embodiment, the driving element 51 and the hook 53 are both coupled to the refrigeration cabinet 10, and the hook 53 is switched between a locking state of the hook and a releasing state of the hook under the driving force generated by the driving element 51. The cabinet door 30 has a closing tendency relative to the refrigeration cabinet 10 when the hook is in the locking state, and the cabinet door 30 is closed relative to the refrigeration cabinet 10 when the hook 53 is in the avoiding state. The driving piece 51 drives the hook 53 to switch between a locking state and an avoiding state, and when the hook 53 is in the locking state, the hook is matched with the buckle and drives the cabinet door 30 to close towards the refrigeration cabinet body 10 through the buckle; when the cabinet door 30 is completely closed, the driving member 51 drives the hook 53 to switch to the avoiding state, and the hook 53 is separated from the hook, so that the cabinet door 30 is not prevented from being normally opened.

Specifically, the hook 53 includes a transmission portion 532 and a hook portion 534 (as shown in fig. 2), the transmission portion 532 is in transmission connection with the driving element 51, and the hook portion 534 extends into the bayonet of the buckle in the locking state to apply a pulling force in cooperation with the buckle.

That is to say, after the end of the buckle far from the hinge point a between the cabinet door 30 and the refrigeration cabinet 10 is matched with the latch mechanism 52, the latch mechanism 52 applies a latch force, the application point of the latch force is far from the hinge point a between the cabinet door 30 and the refrigeration cabinet 10, and the latch force required for closing the cabinet door 30 is small and labor-saving.

Further, the buckle has buckle position 541, buckle position 541 has an opening facing away from cabinet door 30 and refrigeration cabinet body 10 hinge joint, and latch mechanism 52 can stretch into buckle position 541 from the opening, and abut against the inner wall of one side of refrigeration cabinet body 10 close to buckle position 541, drive buckle 54 and the cabinet body to rotate towards the direction close to refrigeration cabinet body 10, seal the refrigeration space, prevent the condition that cabinet door 30 is not closed tightly.

Further, the hook 53 is rotatably disposed on the top of the refrigeration cabinet 10 around a rotation axis relative to the refrigeration cabinet 10, and the buckle is disposed on the top of the cabinet door 30 corresponding to the hook 53. Thus, the hook 53 can rotate under the action of the driving element 51 to protrude out of one side of the refrigeration cabinet 10 close to the cabinet door 30 so as to be buckled with the buckle on the cabinet door 30; the hook 53 can also retract to the top of the refrigeration cabinet 10 under the action of the driving element 51, so as not to hinder the normal opening and closing of the cabinet door 30. Alternatively, the drive member 51 is an electric motor. Moreover, a storage groove is concavely arranged at the top of the refrigeration cabinet body 10, the storage groove is used for storing the driving piece 51, and the driving piece 51 cannot completely protrude out of the top of the refrigeration cabinet body 10, so that the top of the refrigeration cabinet body 10 is relatively flat.

The locking mechanism 52 further includes a transmission assembly 55, the transmission assembly 55 is disposed between the driving member 51 and the hook 53 to drive the hook 53 to rotate around a rotation axis, and the transmission assembly 55 converts the rotation amplitude output by the driving member 51 to finely control the rotation of the hook 53, thereby improving the control accuracy.

Specifically, the transmission assembly 55 includes a driving wheel 552 for cooperating with the driving member 51, a driven wheel 554 for cooperating with the hook 53, and a transmission belt 556 sleeved outside the driving wheel 552 and the driven wheel 554. The driven wheel 554 and the hook 53 are driven to rotate by the transmission belt, and the noise is low.

Optionally, the driving wheel 552 is in tooth meshing transmission with the output end of the driving member 51, so that when the output end of the driving member 51 rotates, the driving wheel 552 is driven to rotate through tooth meshing; driven wheel 554 is in toothed engagement with catch 53 so far, so that when driven wheel 554 rotates, catch 53 is driven to rotate by the toothed engagement.

The locking device 50 further includes a limiting member 56, the limiting member 56 is fixed to the refrigeration cabinet 10 and located at the limit position after the hook 53 moves to the position where the hook is disengaged from the buckle, so as to limit the movement range of the hook 53 and prevent the movement range of the hook 53 from being too large.

The refrigeration equipment further comprises a controller and a detector, wherein the detector is used for detecting whether the cabinet door 30 is closed relative to the refrigeration cabinet body 10, and when the controller detects that the cabinet door 30 is opened relative to the refrigeration cabinet body 10, the controller controls the locking mechanism 52 to generate locking force on the cabinet door 30 to drive the cabinet door 30 to be closed.
