Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to refrigeration equipment. Background Technology

[0002] Taking refrigerators as an example, in order to facilitate the pulling out of the entire storage space to access food, refrigeration equipment is usually equipped with drawer doors. That is, part of the freezer or refrigerator compartment exists in the form of drawers. The drawer doors can be pulled out completely, allowing users to easily view and access all the food, especially items stored deep inside the refrigerator.

[0003] Typically, drawer doors are connected to the refrigerator body by sliding rails. Opening and closing the drawer is achieved through the movement of these rails, and the door is locked in place by springs in the rails themselves when closed. However, since the drawer door's support also primarily comes from the rails, the springs in these rails must overcome the load of the door and drawer interior, the friction from wear and tear on the rails over time, and the resistance from frost buildup on the metal rails after freezing in the freezer. If these resistances exceed the spring force of the rails, the door will not close tightly. Therefore, existing refrigeration equipment drawer doors suffer from the problem of not closing tightly after prolonged use, affecting the refrigeration performance of the equipment. Summary of the Invention

[0004] Therefore, it is necessary to provide a refrigeration device that addresses the problem of drawer doors in existing refrigeration equipment not closing tightly after long-term use.

[0005] A refrigeration device includes a cabinet, a door, and a locking assembly; the cabinet includes an open refrigerated space; the door is slidably connected to the cabinet and closes the open, the door being configured to move relative to the cabinet along a closed path; the locking assembly includes a drive member, a fixing member, and a moving member, the fixing member being fixedly connected to the door, and the moving member being rotatably connected to the cabinet, the drive member being used to drive the moving member to rotate forward and in reverse, and the fixing member being partially located on the reverse rotation path of the moving member; when the moving member abuts against the fixing member, the locking assembly applies force to the door to move the door along the closed path to a position abutting against the cabinet, and keeps the door abutting against the cabinet.

[0006] In one embodiment, the locking assembly further includes a telescopic rod connected to the movable member, and the driving member is used to drive the telescopic rod to extend or shorten in a direction parallel to the direction of the closed path, so as to drive the movable member to rotate relative to the housing. When the telescopic rod is shortened, the fixing member rotates in the opposite direction to gradually approach and abut against the fixing member. When the telescopic rod is extended, the fixing member rotates in the forward direction to gradually move away from the fixing member.

[0007] In one embodiment, one end of the movable member is a rotating end and the other end is an abutting end. The rotating end is rotatably connected to the housing, and the fixing part is located on the rotation path of the abutting end. The rotating end and the fixing part are respectively located on both sides of the telescopic rod.

[0008] In one embodiment, the movable member has a groove located between the rotating end and the abutting end, and the telescopic rod is slidably connected to the groove. When the telescopic rod is in a shortened state, the telescopic rod abuts against the side wall of the groove and the abutting end abuts against the fixing member.

[0009] In one embodiment, the end face of the fixing member facing the moving member is recessed with an opening groove, and the bottom of the opening groove is a relief surface that conforms to the rotation path of the abutting end.

[0010] In one embodiment, the drive is configured to trigger and cause the moving member to rotate in the opposite direction when the door is in a set position on the closed path.

[0011] In one embodiment, the telescopic rod is provided with a stop block located on the closed path of the door body, and when the door body is in the set position, the door body abuts against the stop block, and the drive member is configured to be triggered when the stop block is subjected to force and drive the telescopic rod to shorten.

[0012] In one embodiment, the refrigeration device further includes a trigger, the drive is controlled by the trigger, and when the trigger is triggered, the drive causes the telescopic rod to extend.

[0013] In one embodiment, a handle groove is provided at the top or bottom of the door body, and when the telescopic rod is in the extended state, the moving distance of the door body is not less than the minimum distance between the handle groove and the end face of the door body away from the box body.

[0014] In one embodiment, the trigger is connected to the housing and positioned toward the door, and the trigger is configured to activate when the door continues to move toward the housing in the extension direction of the closed path.

[0015] The refrigeration equipment provided in the above solution connects the fixing part of the locking assembly to the door body, the moving part is rotatably connected to the cabinet body, and the fixing part is set on the rotation path of the moving part. The driving part provides power to the moving part. When the moving part abuts against the fixing part, under the force of the driving part, the locking assembly has the force to move the door body along the closed path to abut against the cabinet body and keep the door body abutting against the cabinet body. This makes the door body stay against the cabinet body, achieves the effect of pushing the door to close, locks the door body and the cabinet body tightly, and avoids the problem of the door body not closing tightly and affecting the refrigeration efficiency.

[0032] See Figure 1 , Figure 1 This illustration shows a schematic diagram of the structure of a refrigeration device 100 according to an embodiment of this application. The refrigeration device 100 provided in an embodiment of this application can be as follows: Figure 1 The refrigerator shown can also be other devices with refrigeration functions, and is not limited thereto. The refrigeration device 100 includes a cabinet 110, a door 120, and a locking assembly 130. The cabinet 110 includes an open refrigeration space 111 for storing items that need to be refrigerated. For example... Figure 1 As shown, the door 120 is slidably connected to the cabinet 110 and closes the opening. The door 120 is configured to move relative to the cabinet 110 in opposite directions on the opening and closing paths, so that when the door 120 is in the open position, the opening is open to take out and put in food, and when the door 120 is in the closed position, the door 120 and the cabinet 110 together enclose and form a sealed refrigerated space 111.

[0033] Combination Figures 2 to 5 As shown, Figure 2 and Figure 5 The diagram shows a structural schematic of the locking assembly 130 of the refrigeration equipment 100 in different states according to an embodiment of the present application. The locking assembly 130 is used to provide a force to make the door 120 continue to move toward the direction of the cabinet 110 when the door 120 is closed, so as to lock the door 120 and the cabinet 110, thereby avoiding the problem that the door 120 is not closed tightly.

[0034] like Figures 2 to 5As shown, the locking assembly 130 includes a driving member 131, a fixing member 132, and a moving member 133. The fixing member 132 is fixedly connected to the door body 120, and the moving member 133 is rotatably connected to the housing 110. The driving member 131 drives the moving member 133 to rotate in both forward and reverse directions. It should be understood that forward and reverse rotation only indicate opposite directions of rotation and are not intended as limitations. Figure 2 In the perspective shown, clockwise rotation of the moving part 133 is taken as the positive rotation, and counterclockwise rotation is taken as the negative rotation, for example. And as... Figure 5 As shown, the fixing member 132 is located on the opposite rotation path of the moving member 133. When the driving member 131 drives the moving member 133 to rotate in the opposite direction, causing the moving member 133 to abut against the fixing member 132, the locking assembly 130 applies force to the door 120 to move the door 120 along the closed path to the position abutting against the cabinet 110, and keeps the door 120 abutting against the cabinet 110, thereby keeping the door 120 abutting against the cabinet 110, locking the door 120 and the cabinet 110, and avoiding the problem of the door 120 not closing tightly and affecting the refrigeration efficiency.

[0035] like Figures 2 to 5 As shown, in one embodiment, the locking assembly 130 further includes a telescopic rod 134 connected to the movable member 133. The driving member 131 drives the telescopic rod 134 to extend or retract. The telescopic rod 134 can extend and retract in a direction parallel to the direction of the closed path, that is, the telescopic rod 134 can extend and retract in both the closed and open paths. The extension and retraction of the telescopic rod 134 causes the movable member 133 to rotate relative to the housing 110. (Combined with...) Figure 5 As shown, during the shortening of the telescopic rod 134, the fixing member 132 rotates in the opposite direction to gradually approach and abut against the fixing member 132. During the extension of the telescopic rod 134, the fixing member 132 rotates in the forward direction to gradually move away from the fixing member 132, thereby unlocking the door 120 and preventing the moving member 133 from interfering with the movement of the fixing member 132 along the opening path of the door 120. In other embodiments, the driving member 131 can also drive the moving member 133 to rotate through other transmission structures, such as transmission gears.

[0036] like Figure 5 As shown, in one embodiment, one end of the movable member 133 is a rotating end 1331 and the other end is an abutting end 1332. The rotating end 1331 is rotatably connected to the housing 110, and the fixing member 132 is partially located on the rotation path of the abutting end 1332. The rotating end 1331 and the fixing member 132 are located on both sides of the telescopic rod 134, so that the extension and retraction of the telescopic rod 134 can drive the abutting end 1332 of the movable member 133 to rotate around the rotating end 1331, so that the abutting end 1332 can move closer to or away from the fixing member 132.

[0037] like Figures 2 to 5 As shown, in one embodiment, the movable member 133 has a sliding groove 1333, which is located between the rotating end 1331 and the abutting end 1332. The sliding groove 1333 is set at an angle to the extension and retraction direction of the telescopic rod 134, and the telescopic rod 134 is slidably connected to the sliding groove 1333. Figure 2 and Figure 5 As shown, when the telescopic rod 134 is in the retracted state, the telescopic rod 134 abuts against the side wall of one end of the slide groove 1333, and the abutting end 1332 abuts against the fixing member 132. Preferably, as shown... Figure 4 and Figure 5 As shown, when the telescopic rod 134 is in the extended state, it abuts against the side wall of the other end of the slide groove 1333, thereby limiting the extension length of the telescopic rod 134 by the length of the slide groove 1333. In other embodiments, one end of the telescopic rod 134 may be rotatably connected to the fixing member 132, and the other end may be rotatably connected to the housing 110. In this case, the extension and retraction of the telescopic rod 134 can also achieve the effect of driving the moving member 133 to rotate.

[0038] like Figures 2 to 5 As shown, in one embodiment, the end face of the fixing member 132 facing the moving member 133 is recessed with an opening groove 1321, such as... Figure 5 As shown, the bottom of the opening slot 1321 is a clearance surface 1322 that conforms to the rotation path of the abutment end 1332, so as to avoid the fixed part 132 interfering with the forward rotation of the moving part 133. Figure 3 As shown, when the abutting end 1332 and the fixing member 132 abut, there is a gap between the door body 120 and the box body 110. At this time, the abutting end 1332 abuts against a smaller area of ​​the fixing member 132. As the moving member 133 continues to rotate, the depth to which the abutting end 1332 is inserted into the opening groove 1321 increases until it reaches the desired depth. Figure 2 As shown, the abutting end 1332 is fully inserted into the opening groove 1321 and abuts against the fastener 132, so that the abutting area of ​​the two is large and the force is even.

[0039] During the opening of the door 120, if the user directly pulls the door 120, the fixing member 132 will cause the moving member 133 to rotate by a set angle. The moving member 133 will then move out of the moving path of the fixing member 132 to avoid interfering with the direct opening of the door 120. In this embodiment, the moving member 133 has an arc-shaped structure so that the required rotation angle when the moving member 133 leaves the moving path of the fixing member 132 is smaller.

[0040] like Figures 2 to 5 As shown, in one embodiment, the end face of the fixing member 132 that abuts against the moving member 133 is shaped to match the end face of the moving member 133 that abuts against the fixing member 132, so that the force between the two is evenly distributed.

[0041] In some embodiments, the drive element 131 can be configured to be controlled by a switch button connected to a control panel, so that when the user presses the switch button, the drive element 131 drives the telescopic rod 134 to extend or retract, thereby driving the moving element 133 to rotate. This causes the moving element 133 to move the fixed element 132 and the door 120 toward the housing 110 and lock them in place, thus enabling the drive element 131 to automatically close and lock the door 120. However, this places length requirements on the extension distance of the telescopic rod 134 and the rotation path length of the abutment end 1332 of the moving element 133. For example... Figures 2 to 5 As shown, in this embodiment, the telescopic distance of the telescopic rod 134 is much smaller than the moving distance of the door 120 when it is open. In one embodiment, the drive member 131 is configured to trigger and drive the moving member 133 to rotate in the opposite direction when the door 120 is in a set position on the closing path, so as to avoid the telescopic rod 134 from participating in the entire closing process of the door 120. It only participates when the door 120 is at the end of the closing path, that is, when the door 120 is about to close or even in a half-closed state. In this way, while realizing the locking function when the door 120 is closed, the participation of the telescopic rod 134 in the entire closing path is reduced, thereby reducing the structural requirements of the telescopic rod 134 and reducing production and maintenance costs.

[0042] Combination Figure 6 and Figure 7 As shown, in one embodiment, the telescopic rod 134 is provided with a stop 135. The stop 135 is located on the closing path of the door 120, and when the door 120 is in a set position, the door 120 abuts against the stop 135. The drive member 131 is configured to be triggered when the stop 135 is subjected to force, thereby causing the telescopic rod 134 to shorten. It can be understood that when the door 120 abuts against the stop 135 during the closing process, the door 120 exerts a force on the stop 135 to cause the telescopic rod 134 to shorten. Applying force will cause load changes and other effects on the drive component 131. The drive component 131 will recognize this change and automatically start to shorten the telescopic rod 134, that is, to drive the moving rod to rotate in the opposite direction, so that the moving rod gradually approaches and abuts against the fixed block, until the telescopic rod 134 is shortened to abut against the side wall of one end of the slide groove 1333. At this time, the abutting end 1332 abuts against the fixed component 132, and the door 120 is locked by the abutting force between the abutting end 1332 and the fixed component 132. In this embodiment, the drive component 131 is a drive motor. In other embodiments, a position sensor that is triggered at a set position can also be set in the slide rail assembly of the sliding connection box 110 of the door 120. The drive component 131 is triggered after receiving the position signal from the position sensor.

[0043] like Figure 6 and Figure 8As shown, in one embodiment, the refrigeration equipment 100 further includes a trigger 140, and a drive 131 is controlled by the trigger 140. When the trigger 140 is triggered, the drive 131 drives the telescopic rod 134 to extend, thereby driving the stop 135 to move with the telescopic rod 134, so as to push the door 120 to move on the opening path through the stop 135, and at the same time drive the moving part 133 to rotate in the forward direction.

[0044] like Figure 1 As shown, the refrigeration equipment 100 typically also includes other doors that are on the same plane as the outer end face of the door body 120. For the sake of aesthetics, there is usually only a small gap between the door body 120 and the other doors, such as... Figure 7 and Figure 8 As shown, in one embodiment, a handle groove 121 is provided at the top or bottom of the door body 120. It can be understood that when other doors are above the door body 120, the handle groove 121 is located at the top of the door body 120; when other doors are below the door body 120, the handle groove 121 can also be located at the bottom of the door body 120. Figure 7 As shown, when the telescopic rod 134 is in the extended state, the moving distance of the door 120 is not less than the minimum distance between the handle groove 121 and the end face of the door 120 facing away from the housing 110, so that the user can open the door 120 through the handle groove 121. Preferably, when the telescopic rod 134 is in the extended state, the opening of the handle groove 121 protrudes mostly or completely from the plane of the outer end face of the door 120 when it is closed, so as to offset other doors above and below the door 120, making it easier for the user to pull the door 120 through the handle groove 121.

[0045] like Figure 7 and Figure 8 As shown, in one embodiment, the trigger 140 is connected to the housing 110 and positioned towards the door 120. The trigger 140 is configured to activate when the door 120 continues to move towards the housing 110 in the extended direction of the closed path. It is understood that when the door 120 is fully closed, due to the sealing ring between the door 120 and the housing 110 to seal the gap between them, when the door 120 is subjected to external force, it still has the potential to move a small distance towards the housing 110 in the extended direction of the closed path. This movement is achieved by compressing the sealing ring, but does not affect the fact that the door 120 was fully closed before the movement. In practical use, simply adjusting the trigger sensitivity of the trigger 140 so that it is triggered when the door 120 moves a small distance under external force is sufficient to detect the user's door opening request.

[0046] The refrigeration equipment 100 provided in the above solution, when in use:

[0047] When the door 120 needs to be closed: The user pushes the door 120 along the closing path. When the door 120 reaches the set position, the door 120 exerts a force on the stop 135 and the telescopic rod 134 in the extended state, causing the telescopic rod 134 to shorten. This triggers the drive unit 131, causing the telescopic rod 134 to shorten, which in turn causes the moving rod to rotate in the opposite direction, allowing the moving rod to gradually approach and close. Figure 3 The abutting and fixing block is shown until it is as shown. Figure 2 As shown, the telescopic rod 134 is shortened to abut against the side wall of one end of the slide groove 1333. At this time, the abutting end 1332 abuts against the fixing member 132, thus realizing the function of locking the door 120 through the abutting force between the abutting end 1332 and the fixing member 132.

[0048] When the door 120 needs to be opened: The user presses the door 120, causing it to continue moving towards the housing 110 in the extended direction of the closed path. This triggers the trigger 140 positioned towards the door 120. After receiving the electrical signal from the trigger 140, the drive 131 begins to extend the telescopic rod 134. At this time, the stop 135 can push the door 120 to move. Because the fixing member 132 has an opening slot 1321, it will not interfere with the moving member 133, which rotates forward under the drive of the telescopic rod 134, until the telescopic rod 134 is in the position of... Figure 4 In the extended state shown, the door body 120 is as follows Figure 7 As shown, at this time, the opening of the handle groove 121 protrudes mostly or completely from the plane of the outer end face of the door 120 when it is closed, so as to offset other doors above and below the door 120, making it easier for the user to pull the door 120 through the handle groove 121.

[0049] Alternatively, when the door 120 needs to be opened, the user can directly pull the door 120. After the fixing part 132 drives the moving part 133 to rotate at a set angle, the moving part 133 will move out of the moving path of the fixing part 132, so as to avoid the moving part 133 interfering with the direct opening of the door 120.

[0050] The refrigeration equipment 100 provided in the above solution connects the fixing member 132 of the locking assembly 130 to the door 120, and the moving member 133 is rotatably connected to the cabinet 110. The fixing member 132 is set on the rotation path of the moving member 133. The driving member 131 provides power to the moving member 133. When the moving member 133 abuts against the fixing member 132, under the force of the driving member 131, the locking assembly 130 has the effect of driving the door 120 to move along the closed path to abut against the cabinet 110 and maintaining the door 120 abutting against the cabinet 110. This makes the door 120 keep abutting against the cabinet 110, achieving the effect of pushing the door to close, locking the door 120 and the cabinet 110, and avoiding the problem of the door 120 not closing tightly and affecting the refrigeration efficiency.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
