Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a door anti-pinch structure and a refrigerator. Background Technology

[0002] Currently, refrigerators often use hidden handles for aesthetic reasons. However, these refrigerators have small gaps between the door handles, which pose a significant risk of pinching fingers when users hold the handle to close the door. This is especially true for freezer drawer doors, where some users will hold the handle to close the door completely, increasing the risk of pinching fingers. Utility Model Content

[0003] Therefore, it is necessary to provide a door anti-pinch structure and refrigerator to solve the problem that users face a greater risk of pinching their hands when using hidden handles in existing refrigerators.

[0004] This application provides a door anti-pinch structure, which includes a box body, a box door, a baffle, and a pusher. The box door is slidably installed on the box body along a first preset direction. The box door includes a main body and a handle. The handle protrudes and is connected to one end of the main body along a second preset direction. The first preset direction and the second preset direction are set at an angle. The baffle is located on the side of the handle near the box body and is movably connected to the main body along the second preset direction. When the box door moves towards the box body, the pusher can apply force to the baffle, so that the baffle moves towards the end of the handle along the second preset direction.

[0005] In one embodiment, the side of the baffle near the handle portion abuts against the handle portion.

[0006] In one embodiment, the box body is provided with a protrusion that protrudes from the surface of the box body and forms the pusher; when the box door moves toward the box body, the protrusion can be inserted between the baffle and the main body to drive the baffle to move along the second preset direction.

[0007] In one embodiment, the protrusion is provided with a guide surface, which is used to contact the baffle and apply force to the baffle; wherein the guide surface is configured as an inclined surface or an arc surface.

[0008] In one embodiment, the protrusion is further provided with an extension surface, which is located on the side of the guide surface away from the handle and connected to the guide surface, and the extension surface is used to fit against the surface of the baffle.

[0009] In one embodiment, along the second preset direction, the distance from the end face of the handle portion away from the main body portion to the extension surface is equal to the thickness of the baffle.

[0010] In one embodiment, a guide post is connected to the baffle, and a guide hole is provided on the main body. Both the guide post and the guide hole extend along the second preset direction, and the guide post is inserted into the guide hole and movably cooperates with the guide hole.

[0011] In one embodiment, the axial length of the guide post is less than or equal to the axial length of the guide hole.

[0012] In one embodiment, a slot is recessed on the surface of the main body near the baffle, the slot is correspondingly disposed to the protrusion, and the protrusion can be inserted into the slot when the door moves toward the box body.

[0013] This application also provides a refrigerator that includes the anti-pinch hand structure for the door as described in any of the above embodiments.

[0014] Compared with the prior art, the anti-pinch structure and refrigerator for the door provided in this application, by setting a baffle on the side of the handle near the body, when the user moves the handle to close the door, the baffle can be lifted by the pusher. The movement of the baffle will reduce the grip space of the user's hand, making it difficult for the user to hold the handle. In this way, it is beneficial to realize the automatic disengagement of the user's hand from the handle on the door before the door is completely closed, reducing the risk of pinching.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1-8 This application provides a cabinet door anti-pinch structure 100, which includes a cabinet body 10 and a cabinet door 20. The cabinet door 20 is slidably installed on the cabinet body 10 along a first preset direction. The cabinet door 20 includes a main body 21 and a handle 22. The handle 22 protrudes and is connected to one end of the main body 21 along a second preset direction. The first preset direction and the second preset direction are set at an angle. It is easy to understand that the handle 22 here is a concealed handle. When the cabinet door 20 is closed, the handle 22 will not protrude from the outside of the cabinet door 20 along the first preset direction (i.e., the push-pull direction), which is not only more aesthetically pleasing but also avoids occupying kitchen space and prevents the handle 22 from bumping into the user, thus preventing accidental injury. The user can open or close the cabinet door 20 relative to the cabinet body 10 by gripping the handle 22 on both sides along the first preset direction.

[0032] It should be noted that the second preset direction can typically be set to the height direction of the anti-pinch structure 100 on the door. For ease of user operation, the handle 22 can be positioned above the door 20. However, this arrangement reduces the gap between the door 20 and the corresponding structure on the cabinet 10 in the second preset direction, increasing the risk of hand pinching when the user closes the door by holding the handle 22. For example, when the door 20 is the freezer door on the refrigerator 200, the gap between the door 20 and the upper refrigerator door is smaller due to the hidden handle. Even when the door 20 is fully closed, the user can still hold the handle 22. If the handle is not pulled out in time, the user's hand may come into contact with the upper refrigerator door, resulting in pinching injury and posing a certain safety risk. Therefore, in order to reduce the risk of pinching the user's hand when closing the door 20 by holding the handle 22, the door anti-pinch structure 100 in this application also includes a baffle 30 and a pusher 40. The baffle 30 is located on the side of the handle 22 near the box body 10 and is movably connected to the main body 21 along the second preset direction. When the door 20 moves toward the box body 10, the pusher 40 can apply force to the baffle 30 so that the baffle 30 moves toward the end of the handle 22 along the second preset direction.

[0033] Understandably, by providing a baffle 30 on the side of the handle 22 near the box 10, when the user moves the handle 22 to close the box door 20, the baffle 30 can be lifted by the pusher 40. The movement of the baffle 30 will reduce the grip space of the user's hand, making it difficult for the user to grip the handle 22. This helps to automatically detach the user's hand from the handle 22 on the box door 20 before the box door 20 is completely closed, reducing the risk of pinching the hand.

[0034] To prevent the baffle 30 from pinching the user's hand during movement, in one embodiment, the side of the baffle 30 closest to the handle 22 abuts against the handle 22. That is, there is no gap between the baffle 30 and the handle 22. When the pusher 40 moves the baffle 30, it can prevent the user's fingers from getting caught in the gap between the baffle 30 and the handle 22, thus improving safety.

[0035] In one embodiment, such as Figure 1As shown, the housing 10 has a protrusion 41 that protrudes from the surface of the housing 10 and forms a pusher 40. When the door 20 moves closer to the housing 10, the protrusion 41 can be inserted between the baffle 30 and the main body 21 to drive the baffle 30 to move in a second preset direction. Thus, by using the protrusion 41 on the surface of the housing 10 to form the pusher 40, the difficulty and cost of setting the pusher 40 can be reduced. Furthermore, the baffle 30 can be automatically raised during the closing of the door 20, making operation simpler. Moreover, the mechanical structure used to control the movement of the baffle 30 makes the structure more reliable. Of course, in other embodiments, the pusher 40 can also use a motor, cylinder, gear, rack, or other structures to achieve the movement of the baffle 30.

[0036] This application specifically uses the pusher 40 as an example, with the protrusion 41 as the example. Based on this, to facilitate the automatic lifting of the baffle 30 during the closing of the door 20, in one embodiment, as... Figures 2-5 As shown, the protrusion 41 is provided with a guide surface 411, which is used to contact and apply force to the baffle 30. The guide surface 411 is configured as an inclined surface or an arc surface. Thus, when the door 20 moves towards the body 10 and reaches the position of the protrusion 41, the protrusion 41 inserts into the gap between the baffle 30 and the main body 21, and contacts the baffle 30 using the guide surface 411. Because the guide surface 411 is inclined or arc-shaped, as the door 20 continues to move, the baffle 30 can automatically rise along the guide surface 411, thereby opening the user's hand and improving safety.

[0037] Furthermore, the protrusion 41 is also provided with an extension surface 412. The extension surface 412 is located on the side of the guide surface 411 away from the handle 22 and is connected to the guide surface 411. The extension surface 412 is used to fit against the surface of the baffle 30. It is easy to understand that when the baffle 30 moves along the guide surface 411 to the connection between the guide surface 411 and the extension surface 412, the baffle 30 is at its highest position and will not continue to move upward. However, the baffle 30 can contact the extension surface 412 and continue to move along the extension surface 412. That is, when the baffle 30 has just moved to its highest position, the door 20 is not completely closed, and there is still a large space above the handle 22 to allow the user's hand, which has been pushed open by the baffle 30, to move back without causing the user's hand to be pinched.

[0038] Specifically, along the second preset direction, the distance from the end face of the handle portion 22 away from the main body portion 21 to the extension surface 412 is equal to the thickness of the baffle 30. Thus, when the baffle 30 moves to its highest position, the baffle 30 is flush with the end face of the handle portion 22, eliminating any gripping space in the handle portion 22 and ensuring that the user's hand can be completely opened. However, this is not a limitation; in other embodiments, when the baffle 30 moves to its highest position, it may be slightly higher or slightly lower than the end face of the handle portion 22, as long as the function of opening the user's hand is achieved, without further limitation here.

[0039] To improve the reliability of the movement of the baffle 30, in one embodiment, such as Figures 6-8 As shown, a guide post 31 is connected to the baffle 30, and a guide hole 211 is provided on the main body 21. Both the guide post 31 and the guide hole 211 extend along a second preset direction, and the guide post 31 is inserted into the guide hole 211 and movably engages with it. The cooperation between the guide post 31 and the guide hole 211 not only simplifies the structure but also effectively improves the straightness of the baffle 30 during movement, ensuring that there is no gap between the baffle 30 and the handle 22, thereby improving the safety when the baffle 30 moves and pushes open the user's hand. Furthermore, the baffle 30 can also be guided by structures such as slide rails, which can be reasonably set according to actual needs.

[0040] Furthermore, in this embodiment, as Figure 6 and Figure 7 As shown, the axial length of the guide post 31 is less than or equal to the axial length of the guide hole 211. Thus, when the door 20 moves away from the protrusion 41, the baffle 30 can automatically descend under the action of gravity, and the baffle 30 can move to contact the end face of the main body 21, thereby improving the stability of the baffle 30 engagement.

[0041] Furthermore, such as Figure 7 and Figure 8 As shown, a slot 212 is recessed on the surface of the main body 21 near the baffle 30. The slot 212 corresponds to the protrusion 41, and when the door 20 moves towards the box body 10, the protrusion 41 can be inserted into the slot 212. In this embodiment, when the door 20 is opened, the baffle 30 contacts the end face of the main body 21. At this time, the gap between the baffle 30 and the main body 21 is small. Therefore, during the closing process of the door 20, it is easy to increase the difficulty for the protrusion 41 to be inserted between the baffle 30 and the main body 21. Based on this, this embodiment provides a slot 212 on the main body 21, so that the protrusion 41 can be smoothly inserted between the baffle 30 and the main body 21, thereby smoothly lifting the baffle 30.

[0042] In other embodiments, the axial length of the guide post 31 may also be greater than the axial length of the guide hole 211. In this case, there is a gap between the baffle 30 and the main body 21 when the door 20 is opened, so the slot 212 may not need to be provided on the main body 21, thereby simplifying the structure. In addition, the automatic reset of the baffle 30 after disengaging from the protrusion 41 can also be achieved by a spring or the like.

[0043] The anti-pinch hand structure 100 for the cabinet door provided in this application mainly includes three states during use, which are defined as the first state, the second state, and the third state, respectively. In the first state, as... Figure 2 As shown, the door 20 is fully open, at which point the door 20 is away from the protrusion 41, and the baffle 30 is fully lowered. Then, as the door 20 moves towards the box body 10, the protrusion 41 first inserts into the slot 212 below the baffle 30, and the baffle 30 contacts the guide surface 411 of the protrusion 41, and... Figure 3 As shown, it gradually rises along guide surface 411, currently in a transitional state between the first and second states. Afterwards, baffle 30 moves along guide surface 411 to its highest position, at which point it is in the transitional state between the first and second states. Figure 4 In the second state shown, the user's hand is fully pushed open, and the door 20 is still some distance from being fully closed. Afterwards, as the door 20 continues to move, as... Figure 5 As shown, the door 20 is completely closed, thus achieving the closing operation.

[0044] The anti-pinch structure 100 for the cabinet door provided in this application allows the cabinet door 20 to be opened by using a push rod (not shown) movably connected to the cabinet body 10. Before the push rod is fully extended, the baffle 30 is fully lowered, thus exposing space for the user to grip the handle 22, allowing the user to open the cabinet door 20 after the push rod is fully extended. During the closing process of the cabinet door 20, the push rod also acts as a buffer, reducing the movement speed of the cabinet door 20 after contact with the push rod, giving the user sufficient time to release their hand from the handle 22 and preventing injury.

[0045] This application also provides a refrigerator 200, which includes the door anti-pinch structure 100 of any of the above embodiments. Furthermore, the refrigerator 200 provided in this application can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the refrigerator 200 to perform corresponding operations, thereby realizing intelligent control of the refrigerator 200 and improving the user experience.

[0046] 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.

[0047] 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 scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
