Description

Technical Field

[0001] The present invention relates to the technical field of locks, and particularly to a door lock and a washing machine. Background Art

[0002] The door lock in a fully automatic washing machine is used to lock the door cover of the washing machine, prevent clothes from being thrown out and water from splashing, and when the handle on the door cover is pulled, the washing machine door can be opened to put the clothes to be washed into the washing machine. The existing washing machine door lock includes a door hook, a lock shell, a rotating member, a rotating member return elastic member, a lock catch, a locking cooperation structure, and a lock catch unlocking structure. When closing the door, the door hook is inserted into the lock shell, the rotating member is driven by the door hook, and the locking cooperation structure guides the lock catch to move from the lock catch return position to the lock catch locking position, blocking the path of the rotation of the rotating member, and the washing machine door is locked; after the clothes are processed, the electromagnetic driving member drives the lock catch to move further in a direction away from the lock catch return position through the lock catch unlocking structure, so that the lock catch no longer blocks the rotation path of the rotating member, and the rotating member rotates under the action of the rotating member return elastic member, and ejects the door hook from the lock shell, and the washing machine door is unlocked.

[0003] However, the above solution has the following deficiencies: The locking cooperation structure on the rotating member includes multiple guiding surfaces and locking surfaces to guide and lock the door hook, making the structure of the rotating member relatively complex, and thus making the preparation of the door lock more cumbersome. Therefore, there is an urgent need to provide a door lock that can avoid the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a door lock and a washing machine, which solve the technical problem of the relatively complex structure of the existing door lock.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The present invention provides a door lock, including:

[0007] A lock shell, with a receiving groove provided on one side of the lock shell, and a first insertion hole provided on the lock shell and communicating with the receiving groove;

[0008] A rotating member, rotatably arranged in the receiving groove, with a second insertion hole provided on the rotating member. The door hook can extend from the first insertion hole into the second insertion hole and drive the rotating member to rotate between an initial position and a locking position. When the rotating member is in the locking position, the first insertion hole and the second insertion hole do not coincide, and the door hook cannot escape from the second insertion hole; and

[0009] A locking device, movably arranged on the lock shell, and capable of locking the rotating member when the rotating member rotates to the locking position.

[0010] The door lock is provided with a receiving groove on one side of the lock housing. A rotating member is rotatably arranged in the receiving groove. A door hook passes through a first insertion hole on the lock housing and a second insertion hole on the rotating member, and drives the rotating member to rotate between an initial position and a locking position. When the rotating member rotates to the locking position, the first insertion hole and the second insertion hole do not coincide, and the lock hook cannot escape from the second insertion hole. At this time, the locking device can lock the locking member. The structure of this door lock is simple and it is easy to achieve locking and unlocking.

[0011] As a preferred solution of the above door lock, the thickness of the bottom of the receiving groove gradually increases from the initial position to the locking position along the rotation direction of the rotating member.

[0012] The thickness of the bottom of the receiving groove gradually increases from the initial position to the locking position along the rotation direction of the rotating member. On the one hand, it can guide the rotating member to rotate to the locking position. On the other hand, when the door hook rotates along the guiding surface, the structure connecting the lock housing and the door hook will be tightened.

[0013] As a preferred solution of the above door lock, it further includes:

[0014] An emergency handle configured to be able to drive the locking device to unlock the rotating member.

[0015] The setting of the emergency handle can drive the locking device to unlock the rotating member, so as to facilitate manual unlocking.

[0016] As a preferred solution of the above door lock, the emergency handle is rotatably arranged on the lock housing. One end of the emergency handle is a driving end, and the other end of the emergency handle can abut against or connect to the locking device.

[0017] The emergency handle is rotatably arranged on the lock housing. By pressing the driving end, the emergency handle can be driven to rotate, so that the other end of the emergency handle abuts against or connects to the locking device, and then drives the locking device to unlock. The rotatably arranged emergency handle makes it more convenient to manually unlock the locking device.

[0018] As a preferred solution of the above door lock, the locking device includes:

[0019] A lock pin movably arranged on the lock housing; and

[0020] A driving component for driving the lock pin to move.

[0021] The lock pin of the locking device is movably arranged on the housing, and the driving component is used to drive the lock pin to move so that the lock pin can lock the rotating member or unlock the rotating member. The structure of the locking device is relatively simple.

[0022] As a preferred solution of the above door lock, the locking device further includes:

[0023] A first elastic reset member configured to drive the lock pin to move towards the rotating member.

[0024] The provision of the first elastic reset member can drive the lock pin to move towards the rotating member, and thus enable the lock pin to automatically reset without external force.

[0025] As a preferred solution of the above door lock, it further includes:

[0026] A first detection circuit including a first conductive switch configured to be triggered to close when the locking device locks the rotating member to conduct the first detection circuit; and / or

[0027] A second detection circuit including a second conductive switch configured to be triggered to close when the rotating member rotates to the locking position to conduct the second detection circuit.

[0028] When the locking device locks the rotating member, the first conductive switch can be triggered to close, thereby conducting the first detection circuit, and then detecting whether the locking device locks the rotating member through the on / off state of the first detection circuit;

[0029] When the rotating member rotates to the locking position, the second conductive switch can be triggered to close, thereby conducting the second detection circuit, and then detecting whether the rotating member rotates in place through the on / off state of the second detection circuit.

[0030] As a preferred solution of the above door lock, the first conductive switch includes:

[0031] A first moving contact piece disposed on the locking device; and

[0032] A first switch disposed on the lock case, and the locking device moves towards the rotating member to drive the first moving contact piece to move and make the first moving contact piece abut against the first switch to conduct the first detection circuit.

[0033] The first conductive switch is structured such that the first moving contact piece is disposed on the locking device and the first switch is disposed on the lock case. When the locking device moves towards the rotating member to drive the first moving contact piece to move and make the first moving contact piece abut against the first switch to conduct the first detection circuit, and then the locking state of the locking device is judged through the on / off state of the first detection circuit. This first conductive switch has a simple structure and is easy to manufacture.

[0034] As a preferred solution of the above door lock, the second conductive switch includes:

[0035] A second switch disposed on the lock case;

[0036] A second movable contact piece, one end of which is connected to the housing of the second switch, and the other end of which is spaced from the contact of the second switch; and

[0037] An abutting member, rotatably arranged on the lock housing, the rotating member rotates from the initial position towards the locking position to drive the abutting member to rotate, and when the locking device is in the locking position, the abutting member presses the second movable contact piece against the contact of the second switch to conduct the second detection circuit.

[0038] The second conductive structure drives the abutting member to rotate through the rotation of the rotating member, and then can press the second movable contact piece against the contact of the second switch to conduct the second detection circuit, so as to detect whether the rotating member rotates in place according to whether the second detection circuit is conducted.

[0039] As a preferred solution of the above door lock, it further includes:

[0040] A limiting groove is circumferentially arranged on the rotating member. When the rotating member rotates to the locking position, the locking device is arranged opposite to the limiting groove.

[0041] By circumferentially arranging a limiting groove on the rotating member, when the rotating member rotates to the locking position, the locking device is arranged opposite to the limiting groove, so that the locking device can extend into the limiting groove to lock the rotating member.

[0042] The present invention also provides a washing machine, including the above door lock. By means of the above door lock, the structure of the washing machine is simplified.

[0043] Advantages of the present invention:

And when the rotating member rotates to the locking position, the first insertion hole and the second insertion hole do not coincide, and the lock hook cannot escape from the second insertion hole. At this time, the locking device can lock the locking member. The structure of this door lock is simple and it is easy to achieve locking and unlocking.

[0045] For the washing machine proposed by the present invention, by means of the above door lock, the structure of the washing machine is simplified. Description of the Drawings

[0064] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of convenience of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0065] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0066] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0067] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0068] Such as Figures 1-5As shown in the figure, this embodiment provides a door lock, which includes a lock case 1, a rotating member 2, and a locking device 3. A receiving groove 11 is provided on one side of the lock case 1, and a first insertion hole 12 communicating with the receiving groove 11 is provided on the lock case 1. The rotating member 2 is rotatably arranged in the receiving groove 11, and a second insertion hole 21 is provided on the rotating member 2. The door hook 8 can extend into the second insertion hole 21 from the first insertion hole 12 and drive the rotating member 2 to rotate between an initial position and a locking position. When the rotating member 2 is in the locking position, the first insertion hole 12 and the second insertion hole 21 do not coincide, and the door hook 8 cannot escape from the second insertion hole 21. The locking device 3 is movably arranged on the lock case 1 and can lock the rotating member 2 when the rotating member 2 rotates to the locking position. The structure of this door lock is simple and it is easy to achieve locking and unlocking.

[0069] As Figure 2 shown in the figure, the door lock further includes a cover plate 7. The cover plate 7 is covered on the side of the lock case 1 where the receiving groove 11 is provided. The rotating member 2 is arranged between the lock case 1 and the cover plate 7. The cover plate 7 makes the appearance of the door lock more beautiful.

[0070] As Figure 4 shown in the figure, a locking groove 112 is provided at the bottom of the receiving groove 11. When the rotating member 12 is in the locking position, it can be engaged with the locking groove 112. The first insertion hole 12 extends in the horizontal direction, and the locking groove 112 extends in the vertical direction. After the door hook 8 extends into the second insertion hole 21 from the first insertion hole 12, driving the door hook 8 to rotate can drive the rotating member 2 to rotate 90° from the initial position to the locking position so as to extend into the locking groove 112.

[0071] As Figure 4 shown in the figure, the thickness of the bottom of the receiving groove 11 gradually increases along the rotation direction of the rotating member 2 from the initial position to the locking position, so that an inclined guiding surface 111 is formed on the inner side surface of the receiving groove 11. The above setting can, on the one hand, guide the rotation of the rotating member 2 and the door hook 8 and make it easy for the door hook 8 to extend into the locking groove 112; on the other hand, when the door hook 8 rotates along the guiding surface 111, the structure connecting the lock case 1 and the door hook 8 will be gradually tightened.

[0072] In order to realize the reset of the rotating member 2, a second elastic reset member (not shown in the figure) is further included. The second elastic reset member is used to drive the rotating member 2 to reset. In this embodiment, the second elastic reset member is a torsion spring. The structure of the torsion spring is simple and can realize the reset of the rotating member 2. Of course, the structure of the second elastic reset member is not limited to the above torsion spring and can also be other structures as long as it can realize the reset of the rotating member 2.

[0073] As Figure 3 、 Figure 6 and Figure 7As shown, the locking device 3 includes a locking pin 31 and a driving member 32. The locking pin 31 is movably arranged on the lock housing 1. In this embodiment, the locking pin 31 is movably arranged on the lock housing 1 in the vertical direction. The driving member 32 is used to drive the locking pin 31 to move so that the locking pin 31 can lock or unlock the rotating member 2, and the structure of the locking device 3 is relatively simple.

[0074] Preferably, the driving member 32 is an electromagnetic driving member. By controlling the on-off of the electromagnetic driving member through a program, the movement of the locking pin 31 in the vertical direction is driven to realize the locking or unlocking of the rotating member 2 by the locking pin 31. The specific structure of the electromagnetic driving member belongs to the prior art and is not specifically limited herein.

[0075] Furthermore, the locking device 3 further includes a first elastic reset member 33. The first elastic reset member 33 is used to drive the locking pin 31 to move towards the direction close to the rotating member 2, so that the locking pin 31 can automatically reset without being affected by external forces.

[0076] As Figure 8 and Figure 9 shown, a limiting groove 22 is circumferentially arranged on the rotating member 2. When the rotating member 2 rotates to the locking position, the locking device 3 is arranged opposite to the limiting groove 22, so that the locking device 3 can lock the rotating member 2 by extending into the limiting groove 22.

[0077] Optionally, as Figures 1-7 shown, the door lock further includes an emergency handle 4. The emergency handle 4 is used to drive the locking device 3 to unlock the rotating member 2, so that manual unlocking can be performed when the electromagnetic driving member fails to drive the locking pin 31 to unlock or in other special cases.

[0078] Specifically, the emergency handle 4 is rotatably arranged on the lock housing 1. One end of the emergency handle 4 is a driving end, and the other end of the emergency handle 4 can abut against or be connected to the locking device 3, thereby driving the locking device 3 to unlock. The rotatably arranged emergency handle 4 makes it convenient to manually unlock the locking device 3.

[0079] Optionally, in order to facilitate the automatic reset of the emergency handle 4 after use, a third elastic reset member 40 (see Figure 6 and Figure 7 ) is provided. The third elastic reset member 40 is used to drive the emergency handle 4 to reset. In this embodiment, the third elastic reset member 40 is a torsion spring arranged on the rotating shaft of the emergency handle 4, and the emergency handle 4 can be reset by the torsion spring. The third elastic reset member 40 can also be other structures as long as the reset of the emergency handle 4 can be realized.

[0080] Optionally, the door lock further includes a first detection circuit and / or a second detection circuit. As Figure 3As shown, the first detection circuit includes a first conductive switch 5. The first conductive switch 5 is used to be triggered and closed when the locking device 3 locks the rotating member 2, so as to conduct the first detection circuit. Then, whether the locking device 3 locks the rotating member 2 is detected by the on / off state of the first detection circuit; the second detection circuit includes a second conductive switch 6. The second conductive switch 6 is used to be triggered and closed when the rotating member 2 rotates to the locking position, so as to conduct the second detection circuit. Then, whether the rotating member 2 rotates in place is detected by the on / off state of the second detection circuit. In this embodiment, the door lock is provided with both the first detection circuit and the second detection circuit, so as to detect whether the locking device 3 locks the rotating member 2 through the first detection circuit, and detect whether the rotating member 2 rotates to the locking position through the second detection circuit, improving the detection accuracy.

[0081] Specifically, as Figure 5 and Figure 6 shown, the first conductive switch 5 includes a first moving contact piece 51 and a first switch 52. The first moving contact piece 51 is arranged on the locking device 3, and the first switch 52 is arranged on the lock case 1. The locking device 3 moves towards the rotating member 2 to drive the first moving contact piece 51 to move and make the first moving contact piece 51 abut against the first switch 52, so as to conduct the first detection circuit. Then, the locking state of the locking device 3 is judged by the on / off state of the first detection circuit. The structure of the first conductive switch 5 is simple and easy to prepare.

[0082] In this embodiment, two first switches 52 are arranged in the first detection circuit, and the two first switches 52 are arranged in parallel. Two first moving contact pieces 51 are correspondingly arranged on the locking device 3. As long as a set of first switch 52 and the corresponding first moving contact piece 51 abut against each other, the first detection circuit can be conducted. Arranging two sets of first conductive switches 5 can avoid the situation that the first detection circuit cannot be conducted due to the damage of the first switch 52 or the first moving contact piece 51, enhancing the detection accuracy of the first detection circuit.

[0083] Specifically, as Figure 7As shown, the second conductive switch 6 includes a second switch 62, a second moving contact piece 61, and an abutting member 63. The second switch 62 is disposed on the lock housing 1. One end of the second moving contact piece 61 is connected to the housing of the second switch 62, and the other end thereof is spaced from the contact of the second switch 62. The abutting member 63 is rotatably disposed on the lock housing 1. The rotating member 2 rotates from the initial position towards the locking position to drive the abutting member 63 to rotate. When the locking device 3 is in the locking position, the abutting member 63 presses against the second moving contact piece 61, causing the second moving contact piece 61 to deform, and then pressing the second moving contact piece 61 against the contact of the second switch 62 to conduct the second detection circuit, so as to detect whether the rotating member 2 rotates in place according to whether the second detection circuit is conducted. The second conductive switch 6 realizes the linkage of the second moving contact piece 61 by the rotation of the rotating member 2, and can be tightly abutted against the second switch 62 through the deformation of the second moving contact piece 61, avoiding the situation where the second conductive switch 6 cannot be conducted.

[0084] Further, in order to prevent the position deviation of the abutting member 63 during rotation, as Figure 8 and Figure 9 shown, an arc-shaped chute 23 is provided along the circumferential direction of the rotating member 2. The abutting member 63 can extend into and move relative to the chute 23. When the rotating member 2 rotates from the initial position to the locking position, when approaching the locking position, the abutting member 63 can abut against the groove wall of the chute 23, and the abutting member 63 is driven to rotate by a certain angle through the continuous rotation of the rotating member 2, so that the abutting member 63 can press against the second moving contact piece 61 and deform the second moving contact piece 61. When the rotating member 2 reaches the locking position, the second moving contact piece 61 presses against the contact of the second switch 62.

[0085] Taking the application of the door lock to a washing machine as an example for illustration: The door lock is installed on the body of the washing machine, and the door hook 8 is installed on the door body.

[0086] Door lock locking process:

[0087] The door hook 8 extends from the first insertion hole 12 into the second insertion hole 21, and rotates the door hook 8 to drive the rotating member 2 to rotate between the initial position and the locking position along the guiding surface 111. After the door hook 8 rotates 90°, it extends into the locking groove 112. At this time, the limiting groove 22 on the rotating member 2 corresponds to the lock pin 31. During the rotation of the rotating member 2, it will abut against the abutting member 63, so that the second moving contact piece 61 contacts the second switch 62, and then conducts the second detection circuit. In the locking position, the lock pin 31 extends into the limiting groove 22 to lock the rotating member 2. At this time, the lock pin 31 moves downward to make the first moving contact piece 51 contact the first switch 52 to conduct the first detection circuit. Whether the lock pin 31 and the rotating member 2 act in place can be judged by the on-off of the first detection circuit and the second detection circuit.

[0088] When unlocked:

[0089] The locking pin 31 is driven to retract by the driving member 32. The locking pin 31 drives the first moving contact piece 51 away from the first switch 52 to disconnect the first detection circuit. The rotating member 2 is driven to rotate under the reverse rotation of the door hook 8, so that the door hook 8 disengages from the locking groove 112. The rotating member 2 has a tendency to rotate back to the initial position under the reset action of the second elastic reset member. By driving the door hook 8 to rotate in the reverse direction, the rotating member 2 is restored to the initial position. When the rotating member 2 rotates during reset, the rotating member 2 gradually disengages from the abutting member 63, so that the second moving contact piece 61 is separated from the second switch 62 to disconnect the second detection circuit. The second insertion hole 21 and the first insertion hole 12 are arranged opposite to each other. At this time, the door hook 8 can be pulled out to achieve unlocking.

[0090] When unlocking in an emergency:

[0091] When the driving device fails to unlock the locking pin 31 or in other special cases, the driving end of the emergency handle 4 can be manually pressed, so that the other end of the driving handle abuts against the locking pin 31, so that the locking pin 31 disengages from the limiting groove 22 of the rotating member 2. By rotating the door hook 8 to drive the rotating member 2 to rotate, the rotating member 2 is restored from the locking position to the initial position.

[0092] This embodiment also provides a washing machine, including the above-mentioned door lock. The door lock is arranged on the cabinet of the washing machine, and the door hook is arranged on the door body of the washing machine. The opening and closing of the door body can be realized by the above-mentioned door lock, and the structure of the washing machine is simplified.

[0093] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
