[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] See also Figure 1 In one embodiment of the present invention, a refrigeration device 100, such as a refrigerator, is provided for keeping items at low temperatures and extending the storage time of the items.

[0030] The refrigeration device 100 includes a refrigeration cabinet 10 and a cabinet door 30. The refrigeration cabinet 10 has a refrigeration space. The cabinet door 30 can be opened and closed relative to the refrigeration cabinet 10 to close or open the refrigeration space. The refrigeration space is used to store items, so that the items are in a low-temperature environment, which can extend the storage time of the items. In addition, the cabinet door 30 can be opened and closed. When it is necessary to store or retrieve items, the cabinet door 30 is opened; when the items are taken out or placed, the cabinet door 30 is closed, and the refrigeration space can be closed, so that the items are in a sealed low-temperature environment. However, during use, it is often the case that the cabinet door 30 is not closed tightly after the items are taken out or placed, which will lead to a waste of energy consumption of the refrigeration device 100.

[0031] See also Figure 1-Figure 3 In order to solve the above technical problems, the present application adds a locking device 50 to the refrigeration equipment 100.

[0032] The lock device 50 includes a lock mechanism 52 and a matching mechanism 54, one of which is disposed on the refrigeration cabinet 10, and the other of which is disposed on the cabinet door 30. The lock mechanism 52 is controlled to act with the buckle 54, and generates a locking force for driving the cabinet door 30 to close relative to the refrigeration cabinet 10. When the user does not close the cabinet door 30 tightly, the lock mechanism 52 can be made to cooperate with the buckle 54 to apply a locking force to the cabinet door 30, drive the cabinet door 30 to move in a direction close to the refrigeration cabinet 10, close the cabinet door 30, and seal the refrigeration space, thereby preventing the cabinet door 30 from being unclosed and causing energy waste, and saving power consumption of the refrigeration device 100.

[0033] The refrigeration space has an opening toward the cabinet door 30, and the cabinet door 30 is hinged to the refrigeration cabinet body 10 and opens or closes the opening. In this way, items are taken into and out of the refrigeration space through the opening, and when the cabinet door 30 moves to completely cover the opening, the refrigeration space can be closed. The direction of the locking force is the direction in which the cabinet door 30 points to the opening, so that the cabinet door 30 is driven to rotate in the direction of covering the opening by the locking force, and the refrigeration space can be closed.

[0034] In some embodiments, the cabinet door 30 is hinged to the refrigerating cabinet 10, the locking mechanism 52 is provided on the refrigerating cabinet 10, and the matching mechanism 54 is provided on the cabinet door 30; the locking mechanism 52 is controlled to act with the matching mechanism 54 and pull the cabinet door 30 to rotate and close relative to the refrigerating cabinet 10. In other words, the locking mechanism 52 cooperates with the matching mechanism 54 and pulls the cabinet door 30 to rotate around the hinge point between the cabinet door 30 and the refrigerating cabinet 10 in a direction close to the refrigerating cabinet 10 to close the refrigerating space of the refrigerating cabinet 10.

[0035] Furthermore, the matching mechanism 54 has a buckle, and the locking mechanism 52 includes a driving member 51 and a hook 53. The hook 53 generates a pulling force to pull the buckle toward the refrigeration cabinet 10 under the action of the driving member 51. The driving member 51 drives the hook 53 to move, and the moving hook 53 hooks the buckle and pulls the buckle toward the refrigeration cabinet 10, thereby driving the cabinet door 30 to rotate toward the refrigeration cabinet 10 to close the refrigeration space.

[0036] When it is detected that the cabinet door 30 is not tightly closed, the driving member 51 is controlled to move, so as to drive the hook 53 to move to protrude from the refrigeration cabinet 10 and contact the buckle 54 on the cabinet door 30. Then, the driving member 51 drives the hook 53 to move in a direction close to the refrigeration cabinet 10, thereby pushing the buckle 54 engaged with the hook 53 and the cabinet door 30 fixedly connected to the buckle 54 to rotate in a direction close to the refrigeration cabinet 10, thereby sealing the refrigeration space of the refrigeration cabinet 10 and closing the cabinet door 30.

[0037] Specifically in the embodiment, the driving member 51 and the hook 53 are both connected to the refrigeration cabinet 10, and the hook 53 switches between a locking state with the buckle and a evasion state separated from the buckle under the driving force generated by the driving member 51. Among them, the cabinet door 30 has a tendency to close 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 evasion state. The driving member 51 drives the hook 53 to switch between the locking state and the evasion state. When the hook 53 is in the locking state, it cooperates with the buckle and drives the cabinet door 30 to close to the refrigeration cabinet 10 through the buckle; when the cabinet door 30 is completely closed, the driving member 51 drives the hook 53 to switch to the evasion state, separates from the hook 53, and does not hinder the normal opening of the cabinet door 30.

[0038] Specifically, the hook 53 includes a transmission portion 532 and a hook portion 534 (eg Figure 2 As shown), the transmission part 532 is in transmission connection with the driving member 51, and the hook part 534 extends into the bayonet of the buckle when in the locked state to cooperate with the buckle to apply tension.

[0039] Optionally, the locking mechanism 52 cooperates with the side of the buckle facing away from the hinge point a of the door 30 and the refrigeration cabinet 10. That is, after the end of the buckle away from the hinge point a of the door 30 and the refrigeration cabinet 10 cooperates with the locking mechanism 52, it is subjected to the locking force applied by the locking mechanism 52. The application point of the locking force is far from the hinge point a of the door 30 and the refrigeration cabinet 10, so the locking force required to close the door 30 is small, which is more labor-saving.

[0040] Furthermore, the buckle has a buckle position 541, which has an opening hinged to the refrigeration cabinet body 10 facing away from the cabinet door 30. The locking mechanism 52 can extend into the buckle position 541 from the opening and abut against the inner wall of the buckle position 541 on the side close to the refrigeration cabinet body 10, thereby driving the buckle 54 and the cabinet body to rotate in a direction close to the refrigeration cabinet body 10, thereby closing the refrigeration space and preventing the cabinet door 30 from being loosely closed.

[0041] Furthermore, the hook 53 is rotatably arranged at the top of the refrigeration cabinet 10 around a rotating shaft relative to the refrigeration cabinet 10, and the buckle 54 is arranged at the top of the cabinet door 30 corresponding to the hook 53. In this way, the hook 53 can be rotated to protrude from the side of the refrigeration cabinet 10 close to the cabinet door 30 under the action of the driving member 51, so as to be engaged with the buckle 54 on the cabinet door 30; the hook 53 can also be retracted to the top of the refrigeration cabinet 10 under the action of the driving member 51, so as not to hinder the normal opening and closing of the cabinet door 30. Optionally, the driving member 51 is a motor. In addition, a recessed receiving groove is provided at the top of the refrigeration cabinet 10, and the receiving groove is used to receive the driving member 51. The driving member 51 will not completely protrude from the top of the refrigeration cabinet 10, so that the top of the refrigeration cabinet 10 is relatively flat.

[0042] The locking mechanism 52 also includes a transmission assembly 55, which is disposed between the driving member 51 and the hook 53 to drive the hook 53 to rotate around a rotating axis. The transmission assembly 55 converts the rotation amplitude output by the driving member 51 to finely control the rotation of the hook 53 and improve the control accuracy.

[0043] Specifically, the transmission assembly 55 includes a driving wheel 552 that cooperates with the driving member 51 for transmission, a driven wheel 554 that cooperates with the hook 53 for transmission, and a transmission belt 556 that is 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 relatively small.

[0044] Optionally, a tooth meshing transmission is formed between the driving wheel 552 and 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 the tooth meshing; and a tooth meshing transmission is formed between the driven wheel 554 and the hook 53, so that when the driven wheel 554 rotates, the hook 53 is driven to rotate through the tooth meshing.

[0045] The locking device 50 further includes a limiter 56 , which is fixed to the refrigeration cabinet 10 and is located at the extreme position after the hook 53 moves to be separated from the buckle 54 , so as to limit the movement range of the hook 53 and prevent the hook 53 from moving too much.

[0046] The refrigeration device also includes a controller and a detector. The detector is used to detect whether the cabinet door 30 is closed relative to the refrigeration cabinet body 10. When the detector detects that the cabinet door 30 is open relative to the refrigeration cabinet body 10, the controller controls the locking mechanism 52 to generate a locking force on the cabinet door 30 to drive the cabinet door 30 to close.

[0047] The movement of the locking device 50 is as follows: Figure 1 As shown, when the cabinet door 30 is in an unclosed state and there is a gap of a certain angle between the cabinet door 30 and the refrigeration cabinet body 10, the detector detects that the cabinet door 30 is opened relative to the refrigeration cabinet body 10, and the controller controls the output end of the driving member 51 to rotate counterclockwise, driving the transmission assembly 55 to move, and then driving the hook 53 to rotate counterclockwise until it is engaged with the buckle 54, applying a locking force to the buckle 54 and the cabinet door 30, driving the cabinet door 30 to rotate closer to the refrigeration cabinet body 10 until the cabinet door 30 is completely closed (such as Figure 2 As shown), close the cabinet door 30. Figure 3 As shown, after the cabinet door 30 is closed for a period of time, the detector detects that the cabinet door 30 is closed relative to the refrigeration cabinet body 10, and the controller controls the output end of the driving member 51 to rotate clockwise, and then drives the hook 53 to rotate clockwise through the transmission assembly 55 until the hook 53 contacts the limit member 56, and the hook 53 returns to the avoidance state. This state does not affect the user's normal door opening and closing operations.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
