[0035] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0036] As Figures 1 to 5 shown, the embodiments of the present disclosure provide a washing machine, which includes a housing 10, a main sealing door 20, a secondary sealing door 30, a locking structure 40, and a lock body 50. The housing 10 is provided with a main washing cavity 11 and a main clothing access opening 12 communicating with the main washing cavity 11. The main sealing door 20 is movably arranged at the main clothing access opening 12. A secondary washing cavity 21 is formed on the main sealing door 20, and a secondary clothing access opening 22 is provided, and the secondary clothing access opening 22 communicates with the secondary washing cavity 21. The secondary sealing door 30 is movably arranged at the secondary clothing access opening 22.

[0037] The locking structure 40 includes a first locking member 41 provided on the main sealing door 20 and a second locking member 42 provided on the auxiliary sealing door 30. The lock body 50 is provided on the housing 10, and the lock body 50 includes a locking engagement member 51 that cooperates with the locking structure 40. When the main sealing door 20 and the auxiliary sealing door 30 are closed to the main clothing access opening 12 and the auxiliary clothing access opening 22 respectively, the first locking member 41 and the second locking member 42 are located on the locking movement direction side of the locking engagement member 51. The locking engagement member 51 moves relative to the first locking member 41 and the second locking member 42 to unlock or lock the first locking member 41 and the second locking member 42 simultaneously.

[0038] The locking engagement member 51 cooperates with the locking structure 40, and the locking engagement member 51 can lock or unlock the locking structure 40. The locking structure 40 includes a first locking member 41 provided on the main sealing door 20 and a second locking member 42 provided on the auxiliary sealing door 30. When the main sealing door 20 and the auxiliary sealing door 30 are closed to the main clothing access opening 12 and the auxiliary clothing access opening 22 respectively, the first locking member 41 and the second locking member 42 are located on the locking movement direction side of the locking engagement member 51, that is to say, the locking engagement member 51 can lock or unlock the first locking member 41 and the second locking member 42 simultaneously. The main sealing door 20 is provided with an auxiliary clothing access opening 22, the auxiliary sealing door 30 is provided on the auxiliary clothing access opening 22, the lock body 50 is provided on the housing 10 and the lock body 50 includes the locking engagement member 51. The user covers the auxiliary sealing door 30 on the auxiliary clothing access opening 22 and pushes the second locking member 42 provided on the auxiliary sealing door 30 towards the lock body 50 so that the locking engagement member 51 locks the second locking member 42. During the process that the user pushes the auxiliary sealing door 30 towards the lock body 50 (that is, towards the housing 10), the auxiliary sealing door 30 drives the main sealing door 20 to move towards the lock body 50 of the housing 10, thereby driving the main sealing door 20 to cover the main clothing access opening 12. The main sealing door 20 moves towards the lock body 50, and the first locking member 41 provided on the main sealing door 20 moves towards the lock body 50, so that the locking engagement member 51 can lock the first locking member 41 and the second locking member 42 simultaneously.

[0039] When the main sealing door 20 covers the main clothing access opening 12 and the auxiliary sealing door 30 covers the auxiliary clothing access opening 22, the locking and mating member 51 moves relative to the first locking member 41 and the second locking member 42, and simultaneously locks the first locking member 41 and the second locking member 42, so as to enable the washing machine to have the guarantee conditions for starting and normal operation. The locking and mating member 51 locks the locking structure 40, which can prevent the main sealing door 20 and / or the auxiliary sealing door 30 from opening during the movement of the washing machine, causing water or clothes in the washing machine to leak out and bringing unnecessary troubles. After the washing is completed or when the user sends a command to open the main sealing door 20 and / or the auxiliary sealing door 30 to the washing machine, the locking and mating member 51 moves in the reverse direction relative to the first locking member 41 and the second locking member 42, and simultaneously unlocks the first locking member 41 and the second locking member 42, enabling the user to open the main sealing door 20 and / or the auxiliary sealing door 30 as needed.

[0040] By adopting this optional embodiment, the main sealing door 20 can be closed while the auxiliary sealing door 30 is closed, and one locking and mating member 51 is used to lock or unlock the first locking member 41 and the second locking member 42 simultaneously. The use of the locking and mating member 51 is reduced, the structure of the washing machine is simplified, the materials of the washing machine are saved, and the production cost of the washing machine is reduced.

[0041] Optionally, the main sealing door 20 is provided with a first handle, and the auxiliary sealing door 30 is provided with a second handle.

[0042] Optionally, the main sealing door 20 includes a front panel and a rear housing. The front panel is provided with the auxiliary clothing access opening 22, and the rear housing and the front panel enclose the auxiliary washing cavity 21.

[0043] The auxiliary clothing access opening 22 is arranged on the front panel, that is, the auxiliary clothing access opening 22 faces the user. In this way, the user only needs to open the auxiliary sealing door 30 to take clothes from the auxiliary washing cavity 21 or place clothes in the auxiliary washing cavity 21, which is convenient for the user's operation.

[0044] Optionally, the front panel includes a heat insulation cover.

[0045] Optionally, the first locking member 41 includes a first mounting portion and a first using portion connected to each other. The first mounting portion is connected to the main sealing door 20, and the connection manner between the first mounting portion and the main sealing door 20 includes but is not limited to bolt connection, rivet connection, welding, bonding or snap connection by a card slot, or when the main sealing door 20 is produced, the first mounting portion is embedded in the main sealing door 20. The first using portion cooperates with the locking and mating member 51.

[0046] Optionally, the second locking member 42 includes a connected second mounting portion and a second using portion. The second mounting portion is connected to the auxiliary sealing door 30. The connection manner between the second mounting portion and the auxiliary sealing door 30 includes but is not limited to bolt connection, rivet connection, welding, bonding or snap connection by a card slot, or when the auxiliary sealing door 30 is produced, the second mounting portion is embedded in the auxiliary sealing door 30. The second using portion cooperates with the locking fitting 51.

[0047] Optionally, the washing machine can be a drum washing machine, a pulsator washing machine or other forms of washing machines.

[0048] In some alternative embodiments, the resistance of the first locking member 41 to the movement of the locking fitting 51 is less than the resistance of the second locking member 42 to the movement of the locking fitting 51. The washing machine further includes a driving device, a current detection device and a controller. The driving device is connected to the locking fitting 51, and the driving device drives the locking fitting 51 to move. The current detection device is connected to the driving device, and the current detection device detects the operating current of the driving device. The controller is connected to the current detection device, and the controller receives the operating current. The controller determines whether the locking fitting 51 is in a locked state with respect to the second locking member 42 according to the magnitude of the operating current.

[0049] With this alternative embodiment, the washing machine includes a driving device that drives the locking fitting 51 to move. During the process of the driving device driving the locking fitting 51 to move, the greater the resistance received by the locking fitting 51, the greater the power of the driving device and the greater the current required by the driving device. The resistance of the first locking member 41 to the movement of the locking fitting 51 is less than the resistance of the second locking member 42 to the movement of the locking fitting 51. Therefore, the operating current of the driving device during the relative movement of the locking fitting 51 with the first locking member 41 is less than the operating current of the driving device during the relative movement of the locking fitting 51 with the second locking member 42. The current detection device detects the operating current of the driving device and transmits the operating current to the controller.

[0050] When the locking fitting 51 locks the second locking member 42, it necessarily locks the first locking member 41, which can ensure that the auxiliary sealing door 30 is covered at the auxiliary clothing access opening 22 and the main sealing door 20 is covered at the main clothing access opening 12. Therefore, the controller determines the locking state of the locking fitting with respect to the second locking member according to the magnitude of the operating current, that is, determines whether the locking fitting 51 locks the second locking member 42, and can judge whether the main sealing door 20 and the auxiliary sealing door 30 respectively cover the main clothing access opening 12 and the auxiliary clothing access opening 22.

[0051] In some alternative embodiments, when the operating current is less than a preset current, the controller determines that the locking engagement member 51 does not lock the second locking member 42. When the operating current is greater than or equal to the preset current, the controller determines that the locking engagement member 51 locks the second locking member 42.

[0052] The operating current of the driving device when the locking engagement member 51 moves relative to the first locking member 41 is less than the operating current of the driving device when the locking engagement member 51 moves relative to the second locking member 42. When the operating current is less than the preset current, it indicates that the second locking member 42 does not exert a resistance on the locking engagement member 51 during the movement of the locking engagement member 51, so it is determined that the locking engagement member 51 does not lock the second locking member 42. That is, the secondary sealing door 30 is not covered at the secondary clothing access opening 22 and / or the main sealing door 20 is not covered at the main clothing access opening 12.

[0053] When the operating current is greater than or equal to the preset current, it indicates that the second locking member 42 exerts a resistance on the locking engagement member 51 during the movement of the locking engagement member 51, so it is determined that the locking engagement member 51 locks the second locking member 42. When the locking engagement member 51 locks the second locking member 42, it will surely lock the first locking member 41, which can ensure that the secondary sealing door 30 is covered at the secondary clothing access opening 22 and the main sealing door 20 is covered at the main clothing access opening 12.

[0054] As Figure 6 shown, an embodiment of the present disclosure provides a control method for a washing machine door lock, including:

[0055] S01, the controller obtains the operating current of the driving device.

[0056] S02, the controller determines whether the operating current is less than the preset current.

[0057] S03, when the operating current is less than the preset current, the controller determines that the locking engagement member 51 does not lock the second locking member 42.

[0058] S04, when the operating current is greater than or equal to the preset current, the controller determines that the locking engagement member 51 locks the second locking member 42.

[0059] Optionally, the washing machine further includes an alarm device, and the controller is connected to the alarm device. When the controller determines that the locking engagement member 51 does not lock the second locking member 42, the controller controls the alarm device to alarm and controls the washing machine to stop running. When the controller determines that the locking engagement member 51 locks the second locking member 42, the controller controls the washing machine to run normally.

[0060] With this alternative embodiment, an alarm can be issued when the secondary sealing door 30 is not covered at the secondary clothing access opening 22 and / or the main sealing door 20 is not covered at the main clothing access opening 12, enabling the user to check whether the main sealing door 20 and the secondary sealing door 30 are closed, and preventing water and clothing from leaking out of the washing machine during operation.

[0061] As Figure 1 shown, in a specific embodiment, the locking engagement member 51 includes a locking tongue 52. The first locking member 41 is provided with a first groove 401, and the second locking member 42 is provided with a second groove 420. The locking tongue 52 can pass through the first groove 401 and the second groove 420. During the movement of the outer wall surface of the locking tongue 52 relative to the inner wall surface of the second groove 420, the outer wall surface of the locking tongue 52 abuts against the inner wall surface of the second groove 420. During the movement of the outer wall surface of the locking tongue 52 relative to the inner wall surface of the first groove 401, there is a gap between the outer wall surface of the locking tongue 52 and the inner wall surface of the first groove 401.

[0062] During the movement of the outer wall surface of the locking tongue 52 relative to the inner wall surface of the first groove 401, there is a gap between the outer wall surface of the locking tongue 52 and the inner wall surface of the first groove 401. In this way, there is no contact between the outer wall surface of the locking tongue 52 and the inner wall surface of the first groove 401, so that the first locking member 41 does not exert resistance on the movement of the locking tongue 52. During the movement of the outer wall surface of the locking tongue 52 relative to the inner wall surface of the second groove 420, the outer wall surface of the locking tongue 52 abuts against the inner wall surface of the second groove 420, so that the second locking member 42 exerts resistance on the locking tongue 52. With this alternative embodiment, during the relative movement of the locking tongue 52 with respect to the first groove 401 and the second groove 420, the resistance received by the locking tongue 52 changes, so that the driving device generates different operating currents. The controller can determine whether the main sealing door 20 and the secondary sealing door 30 are respectively covered at the main clothing access opening 12 and the secondary clothing access opening 22 according to the magnitude of the current detected by the current detection device.

[0063] Optionally, the circles where the first groove 401 is located, the circle where the second groove 420 is located, and the circle where the locking tongue 52 is located are coaxial. The cross-sectional area of the first groove 401 is larger than the cross-sectional area of the locking tongue 52, and the cross-sectional area of the second groove 420 is smaller than or equal to the cross-sectional area of the locking tongue 52.

[0064] In another specific embodiment, the locking engagement member 51 includes a locking tongue 52. The first locking member 41 is provided with a first groove 401, and the second locking member 42 is provided with a second groove 420. The locking tongue 52 can pass through the first groove 401 and the second groove 420. During the movement of the locking tongue 52 relative to the first groove 401 and the second groove 420, the outer wall surface of the locking tongue 52 abuts against the inner wall surfaces of the first groove 401 and the second groove 420. The frictional force between the inner wall surface of the first groove 401 and the outer wall surface of the locking tongue 52 is less than the frictional force between the inner wall surface of the second groove 420 and the outer wall surface of the locking tongue 52.

[0065] The frictional force between the inner wall surface of the first groove 401 and the outer wall surface of the locking tongue 52 is less than the frictional force between the inner wall surface of the second groove 420 and the outer wall surface of the locking tongue 52. That is to say, the resistance exerted by the first groove 401 on the movement of the locking tongue 52 is less than the resistance exerted by the second groove 420 on the movement of the locking tongue 52. By adopting this alternative embodiment, during the relative movement of the locking tongue 52 with respect to the first groove 401 and the second groove 420, the resistance received by the locking tongue 52 changes, so that the driving device generates different operating currents. The controller can determine whether the main sealing door 20 and the sub-sealing door 30 are respectively covered on the main clothing access opening 12 and the sub-clothing access opening 22 according to the magnitude of the current detected by the current detection device.

[0066] Optionally, the smoothness of the inner wall surface of the first groove 401 is greater than that of the inner wall surface of the second groove 420, so that the frictional force between the inner wall surface of the first groove 401 and the outer wall surface of the locking tongue 52 is less than the frictional force between the inner wall surface of the second groove 420 and the outer wall surface of the locking tongue 52.

[0067] Optionally, the first locking member 41 includes a first locking hook, and the first locking hook is provided with a first groove 401. The second locking member 42 includes a second locking hook, and the second locking hook is provided with a second groove 420.

[0068] As Figure 1 and Figure 2 shown, in some alternative embodiments, the sub-sealing door 30 and the lock body 50 are respectively located on opposite sides of the main sealing door 20.

[0069] By adopting this alternative embodiment, when the locking engagement member 51 locks the second locking member 42, the sub-sealing door 30 covers the sub-clothing access opening 22, and presses the main sealing door 20 between the sub-sealing door 30 and the housing 10, so that the main sealing door 20 covers the main clothing access opening 12. Thus, while locking the sub-sealing door 30, the main sealing door 20 is locked. It prevents the situation where only the sub-sealing door 30 is locked and the main sealing door 20 is not locked, and avoids the situation where the controller makes a misjudgment, improving the accuracy of the operation of the washing machine.

[0070] When there is a gap between the outer wall surface of the locking tongue 52 and the inner wall surface of the first groove 401, locking the first locking member 41 by the locking tongue 52 may cause the main sealing door 20 to shake, and it is impossible to seal the main laundry access opening 12, resulting in water leakage of the washing machine. The secondary sealing door 30 presses the main sealing door 20 between the secondary sealing door 30 and the housing 10, so that the main sealing door 20 cannot shake, and the main sealing door 20 seals the main laundry access opening 12.

[0071] Optionally, the cross-sectional areas of the secondary sealing door 30 and the main sealing door 20 are the same. The secondary sealing door 30 covers the main sealing door 20 to maintain the aesthetics of the washing machine.

[0072] Optionally, the first handle is provided on the annular side wall of the main sealing door 20, and the second handle is provided on the front side wall of the secondary sealing door 30.

[0073] When the secondary laundry access opening 22 is in the closed state and the user opens the main laundry access opening 12, the user pulls the main sealing door 20. During the process of the user pulling the main sealing door 20, the main sealing door 20 drives the secondary sealing door 30 to move. The weight of the secondary sealing door 30 is light, and the secondary sealing door 30 is prone to shaking under force. During the shaking of the secondary sealing door 30, it is easy to hurt the user or collide with other objects, or cause the clothes in the secondary washing cavity 21 to fall out.

[0074] As Figure 1 and Figure 3 shown, in some alternative embodiments, the first locking member 41 is provided with an avoidance hole 410, and the avoidance hole 410 extends along the length direction of the locking structure 40. The second locking member 42 can be located in the avoidance hole 410 so that the secondary sealing door 30 covers the secondary laundry access opening 22.

[0075] With this alternative embodiment, when the secondary sealing door 30 covers the secondary laundry access opening 22, the second locking member 42 is located in the avoidance hole 410. The inner side wall of the avoidance hole 410 limits the second locking member 42 to prevent the secondary sealing door 30 from moving relative to the secondary laundry access opening 22 when the user does not pull the secondary sealing door 30. Thus, the washing machine is made safer.

[0076] Optionally, the main sealing door 20 is provided with a through hole, and the through hole is communicated with the avoidance hole 410 and is located on the same straight line. When closing the secondary laundry access opening 22, the secondary sealing door 30 drives the second locking member 42 to pass through the through hole and be located in the avoidance hole 410.

[0077] Optionally, the avoidance hole 410 is communicated with the first groove 401. In this way, the locking tongue 52 can pass through the first groove 401 and cooperate with the second groove 420 of the second locking member 42 to lock the second locking member 42.

[0078] Optionally, with the lower end of the main sealing door 20 as the reference point, the upper end of the main sealing door 20 inclines towards the main clothing access opening 12. When the main sealing door 20 covers the main clothing access opening 12, the main sealing door 20 is in an inclined state. The main sealing door 20 is relatively heavy. When the main sealing door 20 inclines towards the main clothing access opening 12, under the action of the gravity of the main sealing door 20, the main sealing door 20 covers the main clothing access opening 12, preventing the main sealing door 20 from being bounced back when contacting the housing 10.

[0079] Meanwhile, during the operation of the washing machine, the clothes and water in the main washing cavity 11 collide with the main sealing door 20, applying an opening force to the main sealing door 20. The main sealing door 20 is inclined, and its own gravity can be used to offset this opening force. The mating force of the locking fitting 51 on the locking structure 40 is reduced, thereby reducing the burden on the locking fitting 51 and increasing the service life of the locking fitting 51.

[0080] In some alternative embodiments, the lock body 50 is provided with a locking space 510. The locking space 510 extends along the movement direction of the locking structure 40. The main sealing door 20 and the secondary sealing door 30 drive the first locking member 41 and the second locking member 42 into the locking space 510, and the locking fitting 51 extends into the locking space 510 to lock the first locking member 41 and the second locking member 42.

[0081] With this alternative embodiment, the locking space 510 extends along the movement direction of the locking structure 40, enabling the first locking member 41 and the second locking member 42 to enter the locking space 510. The lock body 50 is provided with the locking space 510, and the locking structure 40 and the locking fitting 51 cooperate within the locking space 510, which can protect the locking structure 40 and the locking fitting 51, preventing other objects from obstructing the movement of the locking fitting 51, causing misjudgment by the controller, or even damaging the locking fitting 51. The service life of the washing machine is increased and the aesthetics of the washing machine is maintained.

[0082] The main sealing door 20 is connected to the housing 10 through a first hinge, and the secondary sealing door 30 is connected to the main sealing door 20 through a second hinge. The opening methods of both the main sealing door 20 and the secondary sealing door 30 are flip - type door opening. During the rotation of the main sealing door 20 and the secondary sealing door 30, the movement trajectories of the first locking member 41 and the second locking member 42 are arc - shaped.

[0083] Optionally, the inner wall surface of the locking space 510 includes a guiding wall surface to guide the locking structure 40 to move into the locking space 510. In this way, during the operation of the first locking member 41 and the second locking member 42, the first locking member 41 and / or the second locking member 42 abuts against the guiding wall surface and moves relative to the guiding wall surface to move into the locking space 510.

[0084] Such as Figure 3 、 Figure 4 andFigure 5 As shown, in some alternative embodiments, the washing machine further includes a secondary drum 23. The secondary drum 23 is rotatably disposed in the secondary washing chamber 21, and there is a gap between the secondary drum 23 and the inner side wall of the secondary washing chamber 21. The secondary sealing door 30 includes a door body 31 and a bump 32. The bump 32 is disposed on the inner wall surface of the door body 31, and at least a part of the bump 32 extends towards the secondary drum 23 and extends into the secondary drum 23 to block the gap.

[0085] In this embodiment, the secondary drum 23 can be used to wash small items of clothing, such as underwear, socks and baby clothes, realizing classified washing of the washing machine. At the same time, it saves the user's cost of purchasing an additional small washing machine, saves space and cost, and has strong practicability.

[0086] The bump 32 is disposed on the inner wall surface of the door body 31, and at least a part of the bump 32 extends towards the secondary drum 23 and extends into the secondary drum 23, which can prevent clothes from falling into the gap between the secondary drum 23 and the secondary washing chamber 21 and affecting the normal operation of the washing machine. With this alternative embodiment, the stability of the washing machine operation is ensured.

[0087] Optionally, the bump 32 is circular and the lower part of the bump 32 extends into the secondary drum 23. Due to the action of gravity, the clothes fall from top to bottom or are located at the lower part of the secondary drum 23 driven by the secondary drum 23. The lower part of the bump 32 extends into the secondary drum 23, which can prevent clothes from falling into the gap between the secondary drum 23 and the secondary washing chamber 21 and affecting the normal operation of the washing machine.

[0088] Optionally, the thickness of the lower end of the bump is greater than the thickness of the upper end of the bump.

[0089] In some alternative embodiments, along the extending direction of the locking engagement member 51, the cross-sectional area of the locking engagement member 51 gradually decreases.

[0090] With this alternative embodiment, during the process of the locking engagement member 51 extending to lock the locking structure 40, the locking structure 40 is gradually tightened to realize the locking of the main sealing door 20 and the secondary sealing door 30.

[0091] During the process of the locking engagement member 51 unlocking the locking structure 40, it is very labor-saving for the locking engagement member 51 to retract, avoiding jamming phenomenon.

[0092] Optionally, the part of the locking tongue 52 cooperating with the first groove 401 and the second groove 420 is frustum-shaped.
