Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a locking mechanism and kitchenware cleaning equipment. Background Art

[0002] For example, cleaning cabinets, disinfection cabinets, dishwashers and other appliances are equipped with a locking mechanism, and the locking mechanism is used to lock and unlock the cabinet and the door cover to be locked. In order to prevent the door cover to be locked from being accidentally opened by children touching the locking mechanism, the existing locking mechanism is installed at a higher position of the appliance, or in some small and difficult to observe and touch areas of the appliance, which brings new problems. It is difficult to switch the locking and unlocking states of the locking mechanism, and it is difficult for users to quickly complete it by blind operation. Utility Model Content

[0003] In view of this, the utility model provides a locking mechanism and a kitchen utensil cleaning device which are easier to operate and allow the user to quickly complete state switching in a blind operation manner.

[0004] The locking mechanism provided by the utility model includes a lock body arranged on a first locked structure, a base body arranged on a second locked structure, and a sliding piece movably arranged on the base body, one of the sliding piece and the base body is provided with a guide rail, and the other includes a reciprocating part, which is reciprocatingly movably arranged on the guide rail to adjust the locking force of the locking mechanism; and the reciprocating part can rotate relative to the guide rail at any position on the guide rail to connect or disconnect the sliding piece to or from the lock body.

[0005] The locking mechanism of the utility model is simple in structure and easy to use. The user can switch the locking mechanism to a locked state and an unlocked state more quickly and easily with less operation. The switching can be completed by simply applying force to the sliding member to make the reciprocating part move and rotate relative to the guide rail at the same time.

[0006] In one embodiment, the lock body includes a lock hook, the sliding member includes a locking portion, and the reciprocating portion is used to rotate relative to the guide rail to drive the locking portion to hook against or disengage from the lock hook.

[0007] With such arrangement, the locking portion forms a stable locking connection between the sliding piece and the lock body by hooking the lock hook, thereby preventing connection failure between the sliding piece and the lock body.

[0008] In one embodiment, the locking portion hooks against the back side of the lock hook, and the guide rail defines opposite unloading directions and loading directions. When the reciprocating portion moves along the unloading direction, the pressure of the locking portion on the back side decreases, and when the reciprocating portion moves along the loading direction, the pressure of the locking portion on the back side increases.

[0009] With such arrangement, when unlocking and opening the lock mechanism, it is only necessary to ensure that the force applied to the sliding member has a component that can be decomposed into a force unloading direction, and when locking the lock, it is only necessary to ensure that the force applied to the sliding member has a component that can be decomposed into a force loading direction.

[0010] In one embodiment, it also includes a connecting member movably arranged on the base body, the sliding member includes a lifting portion connected to the connecting member, and the connecting member is used to drive the lifting portion to move, so as to drive the reciprocating portion to move and rotate relative to the guide rail at the same time.

[0011] In this way, when the connecting part is subjected to an external force in a direction away from the second locked structure, the force applied by the connecting part to the lifting part causes the lifting part to move away from the second locked structure, and the reciprocating part synchronously moves and rotates relative to the guide rail, thereby causing the sliding part to rotate and change its posture, thereby causing the sliding part to detach from the lock body; when the connecting part is subjected to an external force in a direction close to the second locked structure, the force applied by the connecting part to the lifting part causes the lifting part to move close to the second locked structure, and the reciprocating part synchronously moves and rotates relative to the guide rail, thereby causing the sliding part to rotate and change its posture, thereby causing the sliding part to approach to connect to the lock body.

[0012] In one embodiment, the guide rail defines opposite unloading directions and loading directions, the connecting member is used to drive the lifting portion away from the second locked structure to drive the reciprocating portion to move along the unloading direction, and the connecting member is used to drive the lifting portion close to the second locked structure to drive the reciprocating portion to move along the loading direction.

[0013] In this way, when the connecting part is subjected to an external force in a direction away from the second locked structure, the lifting part moves away from the second locked structure, and the reciprocating part rotates relative to the guide rail and moves in the force unloading direction at the same time, so that the sliding part is separated from the lock body; when the connecting part is subjected to an external force in a direction close to the second locked structure, the lifting part moves close to the second locked structure, and the reciprocating part rotates relative to the guide rail and moves in the loading direction at the same time, so that the sliding part is close to connect to the lock body.

[0014] In one embodiment, the sliding member includes a locking portion for connecting to the lock body, and the lifting portion is located between the locking portion and the end portion.

[0015] With this arrangement, the relative positional relationship among the seat body, the connecting member and the sliding member is reasonable, the overall lock structure is more compact, and when the sliding member moves relative to the seat body, the connecting member will not interfere with or hinder the sliding member from detaching from the lock body or connecting to the lock body.

[0016] In one embodiment, the tilting portion is rotatably connected to the connecting member; and / or the connecting member is rotatably disposed on the base.

[0017] In one embodiment, the lifting portion is rotatably connected to the connecting member, and the connecting member is rotatably provided on the base body. When the lifting portion is away from the second locked structure, the angle between the sliding member and the second locked structure increases and the angle between the sliding member and the connecting member decreases. When the lifting portion is close to the second locked structure, the angle between the sliding member and the second locked structure decreases and the angle between the sliding member and the connecting member increases.

[0018] In this way, the seat body, the sliding member and the connecting member form a movable triangular connecting rod structure. The reason why the triangular connecting rod structure is movable is that the reciprocating part can be reciprocated on the guide rail. The triangular connecting rod structure formed by the above three is simple in structure, reliable and durable, has a definite deformation movement law, and can respond quickly and sensitively to external forces, and can more efficiently realize the switching of the locking mechanism to the locked state and the unlocked state.

[0019] In one embodiment, when the sliding member is rotated to a position where the lock body is locked and connected to the sliding member, at least a portion of the sliding member forms a fixed fit with the seat body.

[0020] With this arrangement, while the slide member and the lock body form a locking connection, the seat body applies a restraining force to the slide member by forming a fixed fit with the slide member, thereby achieving double fixation of the slide member and reducing the risk of connection failure between the slide member and the lock body.

[0021] The kitchenware cleaning device provided by the utility model comprises a cabinet, a door cover and the above locking mechanism, wherein the lock body is arranged at one of the cabinet and the door cover, and the seat body is arranged at the other of the cabinet and the door cover.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field 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 "or / and" used herein includes any and all combinations of one or more related listed items.

[0027] The utility model provides a locking mechanism 100 that can be used in equipment such as a cleaning cabinet, a disinfection cabinet, and a dishwasher. In addition, a kitchenware cleaning device equipped with the locking mechanism 100 is provided. The kitchenware cleaning device can be any one of the cleaning cabinet, the disinfection cabinet, and the dishwasher, or other types of kitchenware cleaning devices. Generally, equipment such as a cleaning cabinet, a disinfection cabinet, and a dishwasher include a cabinet and a door cover. The cabinet is hollow inside to form a cavity for washing or placing kitchenware. The door cover can be movably installed on the cabinet, and the cabinet can be opened to open the cavity, and the cabinet can be closed to close the cavity.

[0028] The purpose of the lock mechanism 100 of the utility model is that the lock mechanism 100 has a locked state and an unlocked state. When the cabinet is closed by the door cover, the lock mechanism 100 in the locked state is used to limit the position and posture of the door cover and the cabinet to prevent the cabinet from being accidentally opened. When the cabinet needs to be opened, the lock mechanism 100 is switched to the unlocked state, thereby canceling the position and posture and limitation of the door cover and the cabinet. The lock mechanism 100 of the utility model can be installed at a higher position of the kitchen cleaning equipment or other equipment, or it can be installed in a small, hidden and not easily touched area of ​​the kitchen cleaning equipment or other equipment, in order to prevent children from accidentally opening the cabinet by accidentally touching the lock mechanism 100.

[0029] The lock mechanism 100 of the utility model includes a lock body 10 arranged on a first locked structure, a seat body 210 arranged on a second locked structure, and a sliding member 20 movably arranged on the seat body 210. One of the sliding member 20 and the seat body 210 is provided with a guide rail 211, and the other includes a reciprocating portion 21 reciprocatably arranged on the guide rail 211. The reciprocating portion 21 can rotate relative to the guide rail 211 at any position on the guide rail 211. The guide rail 211 defines the trajectory and movement direction of the reciprocating portion 21, that is, the reciprocating portion 21 and the guide rail 211 form not only a relatively movable movable connection, but also a relatively rotatable movable connection. The reciprocating portion 21 can rotate relative to the guide rail 211 to connect or disconnect the sliding member 20 to the lock body 10, and can adjust the locking force of the lock mechanism 100 by moving along the guide rail 211.

[0030] As the sliding member 20 is connected to the lock body 10, the lock mechanism 100 switches to a locked state, and as the sliding member 20 is separated from the lock body 10, the lock mechanism 100 switches to an unlocked state. The locking force of the lock mechanism 100 includes: when the sliding member 20 is connected to the lock body 10, the contact pressure between the sliding member 20 and the lock body 10; when the lock mechanism 100 is installed in the kitchen cleaning equipment and used to lock or unlock the cabinet and the door cover 220, the first locked structure is one of the cabinet and the door cover 220, and the second locked structure is the other of the cabinet and the door cover 220. The direction for the reciprocating part 21 to reciprocate defined by the guide rail 211 includes a force unloading direction and a loading direction that are opposite to each other.

[0031] Figure 1-2 The lock mechanism 100 shown is installed and applied to a kitchen cleaning device, the base body 210 is flat and fixedly mounted on the cabinet, and the lock body 10 is fixedly mounted on the door cover 220. The sliding member 20 includes a locking portion 23, and a locking hole 231 is opened on one side of the locking portion 23. The lock body 10 includes a lock hook 11. When the lock mechanism 100 is in a locked state, the lock hook 11 extends into the locking hole 231 and the locking portion 23 abuts against the back side 111 of the lock hook 11, so that a hooking connection is formed between the locking portion 23 and the lock hook 11. The reciprocating portion 21 and the locking portion 23 are relatively fixed. As the reciprocating portion 21 rotates relative to the guide rail 211 and moves along the guide rail 211 at the same time, the locking portion 23 is driven to a position to hook the lock hook 11, thereby switching the locking mechanism 100 to a locked state, or the locking portion 23 is driven to disengage the lock hook 11, thereby switching the locking mechanism 100 to an unlocked state.

[0032] In some embodiments, the trajectory defined by the guide rail 211 for the reciprocating portion 21 to move back and forth is a linear trajectory, and both the unloading direction and the loading direction are linear directions. Figure 2The locking mechanism 100 shown is in an unlocked state, the sliding member 20 includes a sliding seesaw, which is used to form at least part of the reciprocating part 21, and the guide rail 211 is fixed to the side of the base 210 away from the cabinet, and is provided with a linear slide 2111, which is used to define a linear track for the reciprocating part 21 to reciprocate, and a part of the reciprocating part 21 extends into the slide 2111, and the reciprocating part 21 can slide along the slide 2111, and can also rotate at any position in the slide 2111 to realize the rotation of the reciprocating part 21 relative to the guide rail 211. The extension direction of the slide 2111 is roughly parallel to the base 210 and the cabinet surface for installing the base 210, and the unloading direction is Figure 2 The right direction at the middle viewing angle, the loading direction is Figure 2 In the left direction of the viewing angle, the back side 111 of the locking hook 11 is located Figure 2 The right side of the locking hook 11 in perspective.

[0033] exist Figure 2 On the basis of the locking mechanism 100 shown in the figure, an external force is applied to the sliding seesaw in the direction of the seat body 210 and the cabinet surface for installing the seat body 210, so as to drive the sliding seesaw 20 to rotate clockwise relative to the guide rail 211, and at the same time drive the reciprocating part 21 to slide leftward along the slide groove 2111, so that the angle between the sliding seesaw and the seat body 210 and the angle between the sliding seesaw and the cabinet surface for installing the seat body 210 are reduced, and the locking part 23 can be driven to approach and connect with the lock hook 11. The direction of the force applied to the sliding seesaw is directed to the seat body 210 and the cabinet surface, which means that the force acting on the sliding seesaw has Figure 2 The vertical downward component of the viewing angle. Figure 2 When the locking mechanism 100 shown is in a locked state, the sliding plate is roughly parallel to the extension direction of the slide groove 2111, and the sliding plate is roughly parallel to the base body 210 and the cabinet surface for installing the base body 210. At this time, the lock hook 11 extends into the locking hole 231, and the locking part 23 reaches the right side of the lock hook 11 and abuts against the back side 111 of the lock hook 11.

[0034] exist Figure 2 When the locking mechanism 100 shown is in the locked state, when it is necessary to switch the locking mechanism 100 to the unlocked state again, it is only necessary to apply an external force to the sliding seesaw in a direction away from the seat body 210 and the cabinet surface for installing the seat body 210, so as to drive the sliding member 20 to rotate counterclockwise relative to the guide rail 211, and at the same time drive the reciprocating part 21 to slide to the right along the slide groove 2111, so as to increase the angle between the sliding seesaw and the seat body 210, and the angle between the sliding seesaw and the cabinet surface for installing the seat body 210, and ensure that the external force applied to the sliding seesaw is sufficient to overcome the friction and contact pressure between the locking part 23 and the lock hook 11. The direction of the force applied to the sliding seesaw is away from the seat body 210 and the cabinet surface, which means that the force acting on the sliding seesaw has Figure 2The vertical upward component of the viewing angle.

[0035] Specifically, in Figure 2 When the locking mechanism 100 is in the locked state, if the vertical downward component of the force acting on the sliding seesaw increases, the sliding seesaw is further rotated slightly clockwise, and the reciprocating portion 21 is further slid to the left along the slide groove 2111, the pressure of the locking portion 23 on the back side 111 on the right side of the lock hook 11 is further increased; on the contrary, Figure 2 When the locking mechanism 100 shown is in a locked state, if the vertical downward component of the force acting on the seesaw is reduced, or even a certain force is applied to the seesaw in the vertical upward direction, the seesaw rotates slightly counterclockwise, and at the same time, the reciprocating portion 21 slides slightly to the right along the slide groove 2111, and the pressure of the locking portion 23 acting on the back side 111 on the right side of the lock hook 11 is reduced.

[0036] It can be understood that in other embodiments, when the locking mechanism 100 is switched to the locked state, the locking portion 23 and the lock body 10 can also be connected by other means, such as an interference fit, a plug-in connection, a clamping connection, etc. between the locking portion 23 and the lock body 10. The locking force of the locking mechanism 100 is also correspondingly provided by the locking portion 23 and the lock body 10 that are against each other, and the friction force and contact pressure between the locking portion 23 and the lock body 10 form the locking force.

[0037] In some embodiments, the locking mechanism 100 further includes a connecting member 30 movably disposed on the seat body 210, and the sliding member 20 includes a lifting portion 22 connected to the connecting member 30, and the connecting member 30 is used to drive the lifting portion 22 to move, thereby driving the reciprocating portion 21 to move and rotate relative to the guide rail 211 at the same time. The connecting member 30 has a restraining and guiding effect on the lifting portion 22. When an external force is applied to the sliding member 20, the lifting portion 22 moves along a certain trajectory, thereby the position and posture of the sliding member 20 change according to the law, and the sliding member 20 changes its position and posture along a certain unchanged trajectory, preventing the sliding member 20 from moving along the guide rail 211 only through the reciprocating portion 21, and the sliding member 20 from rotating relative to the guide rail 211 only through the reciprocating portion 21, ensuring that the movement and rotation of the sliding member 20 relative to the guide rail 211 can be performed synchronously at any position of the guide rail 211.

[0038] When the sliding seesaw is subjected to an external force in a direction away from the base 210 and the cabinet surface, the connecting member 30 is also subjected to a force in a direction away from the base 210 and the cabinet surface under the force transmission of the lifting portion 22, and then the connecting member 30 and the lifting portion 22 change their postures at the same time, and the reciprocating portion 21 moves relative to the guide rail 211 in the direction of unloading the force as the posture of the entire sliding seesaw including the lifting portion 22 changes;

[0039] When the sliding seesaw is subjected to an external force in a direction close to the base body 210 and the cabinet surface, the connecting member 30 is also subjected to a force in a direction close to the base body 210 and the cabinet surface due to the force transmission of the lifting portion 22, and then the connecting member 30 and the lifting portion 22 change their postures at the same time, and the reciprocating portion 21 moves relative to the guide rail 211 along the loading direction as the posture of the entire sliding seesaw including the lifting portion 22 changes.

[0040] Specifically, see Figure 1-2 The reciprocating portion 21 includes an end portion 24 and a reciprocating shaft disposed at the end portion 24. The end portion 24 is a part of the sliding seesaw. The locking portion 23 and the lifting portion 22 are both fixed relative to the end portion 24. The lifting portion 22 is disposed between the locking portion 23 and the end portion 24. The connecting member 30 includes a connecting arm 31, a first rotating shaft 321, and a second rotating shaft 322. The first rotating shaft 321 is disposed at one end of the connecting arm 31 and is rotatably connected to the seat body 210. The second rotating shaft 322 is disposed at the other end of the connecting arm 31 and is rotatably connected to the lifting portion 22. Thus, the lifting portion 22 is rotatably connected to the connecting member 30, and the connecting member 30 is rotatably connected to the seat body 210. As the connecting member 30 rotates relative to the seat body 210, the moving track formed by the lifting portion 22 is an arc track. The arc track takes the first rotating shaft 321 as the rotation center and the distance between the first rotating shaft 321 and the second rotating shaft 322 as the radius.

[0041] The moving track of the lifting portion 22 is a fixed arc track, so that the sliding member 20 will no longer randomly form different moving tracks. No matter what position the part of the reciprocating portion 21 extending into the slide groove 2111 is in, the sliding member 20 can move and rotate at the same time. The reciprocating shaft slides along the slide groove 2111 to move the sliding member 20, and the end 24 rotates relative to the guide rail 211 to rotate the sliding member 20. Optionally, the reciprocating shaft is rotatably provided at the end 24, the first rotating shaft 321 is rotatably provided at the connecting arm 31, and the second rotating shaft 322 is rotatably provided at the connecting arm 31. Of course, in other embodiments, the reciprocating shaft can also be fixedly connected to the end 24, and the first rotating shaft 321 and the second rotating shaft 322 can also be fixedly connected to the connecting arm 31.

[0042] Further, see Figure 1-2 ,exist Figure 2 When the locking mechanism 100 shown is in a locked state, in addition to the hooking connection formed between the locking portion 23 and the lock hook 11, the guide rail 211 and the end portion 24, as well as the guide rail 211 and the lift portion 22 are fixedly connected by a tight fit. At this time, there is not only contact pressure between the locking portion 23 and the back side 111 of the lock hook 11, but also contact pressure between the guide rail 211 and the end portion 24, as well as between the guide rail 211 and the lift portion 22, thereby achieving double fixation of the sliding member 20 to prevent accidental detachment and connection failure between the sliding member 20 and the lock body 10.

[0043] Figure 1-2 The action process of the locking mechanism 100 shown is as follows:

[0044] When the user applies a lifting force to the sliding plate in a direction away from the base 210 and the cabinet surface, the sliding plate moves Figure 2 When the angle of view is tilted upward, the second rotation axis 322 and the tilting portion 22 are connected to the second rotation axis 322 at a position around the first rotation axis 321. Figure 2 The whole sliding board rotates clockwise from the viewing angle. Figure 2 The end 24 rotates counterclockwise from the viewing angle, and the reciprocating shaft rotates in a Figure 2 The right side of the viewing angle moves along the slide groove 2111. During this process, the angle between the sliding seesaw and the base 210 increases, the angle between the sliding seesaw and the cabinet surface increases, and the angle between the sliding seesaw and the connecting arm 31 decreases. The locking portion 23 gradually moves away from the locking hook 11 in the counterclockwise direction.

[0045] When the user applies downward pressure to the sliding plate in a direction close to the base 210 and the cabinet surface, the sliding plate moves downward. Figure 2 When the angle of view is pressed downward, the second rotating shaft 322 and the position where the lifting portion 22 connects the second rotating shaft 322 are rotated around the first rotating shaft 321 by Figure 2 The whole slide is rotated counterclockwise from the viewing angle. Figure 2 The end 24 rotates clockwise from the viewing angle, and the reciprocating shaft rotates clockwise from the viewing angle. Figure 2 The left side direction moves along the slide groove 2111 from the perspective. During this process, the angle between the sliding seesaw and the base body 210 decreases, the angle between the sliding seesaw and the cabinet surface decreases, and the angle between the sliding seesaw and the connecting arm 31 increases. The locking part 23 gradually approaches the locking hook 11 in the clockwise direction.

[0046] In other embodiments, the reciprocating portion may also be disposed on the seat body, and the guide rail may be correspondingly disposed in the sliding member, as long as the reciprocating portion can be reciprocatedly disposed on the guide rail and can rotate relative to the guide rail at any position on the guide rail.

[0047] 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.

[0048] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
