Detailed implementation manners

[0063] In order to more clearly understand the above objects, features and advantages of the embodiments of the present invention, the solutions of the embodiments of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0064] Many specific details are set forth in the following description in order to fully understand the embodiments of the present invention, but the embodiments of the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0065] Refer to Figures 1 to 15As shown, this embodiment provides a door lock device. The door lock device 100 can be specifically applied to a clothing processing device. Among them, the clothing processing device can be, for example, a washing machine, a dryer, a washing and drying machine, or a clothing processing cabinet.

[0066] Exemplarily, the clothes processing device includes a box body 500, and a front sealing door 200 is provided on the front side of the box body 500, and the front side of the box body 500 is the side of the box body 500 facing the user. A clothes processing drum 501 is provided in the box body 500, and a clothes loading port connected to the clothes processing drum 501 is provided on the front sealing door 200. The door body 300 is connected to the front sealing door 200 and can be opened and closed relative to the front sealing door 200 to realize the opening and closing of the clothes loading port.

[0067] The door lock device 100 includes a driving mechanism 10 and a connecting member 20. The driving mechanism 10 is arranged on a front sealing door 200 of the clothes processing device.

[0068] The driving mechanism 10 includes a driving structure 1, a transmission structure 2 and a locking member 3. The connecting member 20 is connected between the door body 300 and the transmission structure 2. The locking member 3 is used to lock the driving structure 1 and the transmission structure 2 together or to unlock the driving structure 1 and the transmission structure 2. When the transmission structure 2 is locked with the driving structure 1, the transmission structure 2 can drive the connecting member 20 to move under the drive of the driving structure 1, so that the door body 300 is closed relative to the front sealing door 200, or the door body 300 is opened relative to the front sealing door 200.

[0069] Illustratively, when the locking member 3 locks the driving structure 1 and the transmission structure 2 together, the driving structure 1 can drive the transmission structure 2 to move. Since the connecting member 20 is connected to the transmission structure 2, the transmission structure 2 drives the connecting member 20 to move, thereby realizing the opening and closing of the door body 300 relative to the front sealing door 200, so as to open and close the clothing delivery port, which is convenient for the user to flexibly adjust the opening and closing of the door body 300 according to actual usage needs, and to a certain extent avoids the situation where the user manually opens and closes the door body 300, saves manpower, and thus greatly improves the user's usage experience.

[0070] Exemplarily, taking the laundry treatment device as a dryer as an example, when the door body 300 is closed relative to the front sealing door 200 and the drying operation starts, for example, when drying for ten minutes, the transmission structure 2 drives the connecting member 20 under the driving action of the driving structure 1, so that the door body 300 moves to the open state, opening the laundry feeding port, so that the high-temperature and humid air in the laundry treatment cylinder 501 can be discharged from the laundry feeding port, accelerating the air circulation in the laundry treatment cylinder 501 and improving the drying efficiency of the laundry. For example, one minute after the door body 300 is opened, the driving structure 1 drives the transmission structure 2 to drive the connecting member 20 to drive the door body 300 to move, closing the door body 300 again to avoid the entry of external dust or animals into the laundry treatment cylinder 501 during the drying process. For example, when the drying is completed, the driving structure 1 drives the transmission structure 2 to drive the connecting member 20 to drive the door body 300 to move, opening the door body 300 to facilitate the user to take out the dried laundry. For example, ten minutes after the door body 300 is opened, the door body 300 is closed again through the driving structure 1 to further avoid the entry of external dust or animals into the laundry treatment cylinder 501, ensuring the cleanliness inside the cabinet 500 and providing safety protection for animals and the like.

[0071] Among them, during the entire drying process, the laundry feeding port can be opened and closed multiple times, thereby further accelerating the drying efficiency of the laundry.

[0072] Of course, in some other embodiments, the driving mechanism 10 can also be arranged on the door body 300, and the connecting member 20 is connected between the front sealing door 200 and the transmission structure 2.

[0073] Exemplarily, referring to Figure 2 As shown, for example, a locking hook 301 can be arranged on the door body 300, and a locking groove 2002 can be arranged on the front sealing door 200. For example, the locking hook 301 can be an electromagnetic elastic locking hook, and through the cooperation between the electromagnetic elastic locking hook and the locking groove 2002, the elastic locking between the front sealing door 200 and the door body 300 is realized. For example, the door lock device 100 can be arranged opposite to the locking hook 301 on the laundry treatment device.

[0074] Among them, the laundry treatment device includes a main controller, and the main controller can be electrically connected to the electromagnetic elastic locking hook, and is used to control the cooperation between the electromagnetic elastic locking hook and the locking groove 2002, as well as the disengaging cooperation between the electromagnetic elastic locking hook and the locking groove 2002.

[0075] Exemplarily, when it is necessary to open the door body 300, for example, the main controller can be made to disengage the electromagnetic elastic lock hook from the lock slot 2002, so that the door body 300 is disengaged from the front sealing door 200. Then, the transmission structure 2 is driven by the driving structure 1 to drive the connecting member 20 to move, so that the door body 300 moves away from the front sealing door 200 to open the door body 300. When it is necessary to close the door body 300, the transmission structure 2 is driven by the driving structure 1 to drive the connecting member 20 to move, so that the door body 300 moves towards the front sealing door 200 to close the door body 300. And when the door body 300 is re-closed, the electromagnetic elastic lock hook is locked with the lock slot 2002 to ensure the locking effect of the door body 300.

[0076] Specifically, the connecting member 20 can be, for example, a connecting rod, a connecting block, etc.

[0077] The door lock device provided in this embodiment, by setting the driving mechanism 10 and the connecting member 20, sets the driving mechanism 10 on one of the front sealing door 200 and the door body 300 of the laundry treatment device, so that the driving mechanism 10 includes a driving structure 1, a transmission structure 2 and a locking member 3. The connecting member 20 is connected between the other of the front sealing door 200 and the door body 300 and the transmission structure 2. The locking member 3 is used to lock the driving structure 1 and the transmission structure 2 together or to unlock the driving structure 1 and the transmission structure 2. And when the transmission structure 2 is locked with the driving structure 1, the transmission structure 2 can drive the connecting member 20 to move under the drive of the driving structure 1, so that the door body 300 is closed relative to the front sealing door 200, or the door body 300 is opened relative to the front sealing door 200. That is to say, when the locking member 3 locks and cooperates the driving structure 1 and the transmission structure 2, the driving structure 1 can be used to drive the transmission structure 2, so that the transmission structure 2 drives the connecting member 20 to move, thereby realizing the opening and closing between the door body 300 and the front sealing door 200, which provides great convenience for users and is more labor-saving for users, greatly improving the user experience. For example, when the user needs to ventilate the laundry treatment drum 501, the transmission structure 2 is driven by the driving structure 1 to drive the connecting member 20 to move, so that the door body 300 is opened relative to the front sealing door 200, thereby avoiding the generation of peculiar smell and the breeding of bacteria in the laundry treatment drum 501 to a certain extent. For another example, when it is necessary to dry the clothes through the laundry treatment device, the door body 300 can be opened to accelerate the circulation of the hot air for drying in the laundry treatment drum 501 to improve the drying efficiency of the clothes. For yet another example, the transmission structure 2 can be driven by the driving structure 1 to drive the connecting member 20 to move, so that the door body 300 is closed relative to the front sealing door 200, thereby avoiding the entry of dirt, animals, etc. into the laundry treatment drum 501 to a certain extent, ensuring the cleanliness of the laundry treatment drum 501, and being able to provide safety protection for animals, etc.

[0078] In some embodiments, referring to Figures 4 to 8 As shown, the driving structure 1 includes a first driving member 11 and a first gear set 12 connected to the first driving member 11. The transmission structure 2 includes a second gear set 21 disposed opposite to the first gear set 12. The connecting member 20 is connected to the second gear set 21. The first driving member 11 is used to drive the first gear set 12 to rotate, and the locking member 3 is used to lock the first gear set 12 and the second gear set 21 together or to unlock the first gear set 12 and the second gear set 21. When the second gear set 21 is locked with the first gear set 12, the connecting member 20 is driven to rotate under the drive of the first gear set 12.

[0079] In this way, through the locking member 3, the locking of the first gear set 12 and the second gear set 21 can be realized, so that the first gear set 12 and the second gear set 21 are power-coupled, or the unlocking of the first gear set 12 and the second gear set 21 can be realized to release the power of the first gear set 12 and the second gear set 21, that is, the clutch of the first gear set 12 and the second gear set 21 is realized through the locking member 3.

[0080] Exemplarily, when the first gear set 12 and the second gear set 21 are in the unlocked state, the power transmission between the first gear set 12 and the second gear set 21 is blocked. At this time, the user can manually operate to open and close the door body 300. When it is necessary to open and close the door body 300 through the door lock device 100, the first gear set 12 and the second gear set 21 are locked together by the locking member 3, so that the first gear set 12 and the second gear set 21 are power-coupled and can perform power transmission to rotate synchronously. In this way, when the first driving member 11 drives the first gear set 12 to rotate, the second gear set 21 will rotate synchronously with the first gear set 12 and drive the connecting member 20 to move to realize the opening and closing of the door body 300.

[0081] Of course, in some other embodiments, the driving structure 1 may also include a first driving member and a first coupling connected to the first driving member. The transmission structure includes a second coupling disposed opposite to the first coupling, and the connecting member is connected to the second coupling. The first driving member is used to drive the first coupling to rotate, and the locking member is used to lock the first coupling and the second coupling together or to unlock the first coupling and the second coupling; when the second coupling is locked with the first coupling, it can drive the connecting member to rotate under the drive of the first coupling.

[0082] In addition, the driving structure 1 can also drive the transmission structure 2 to translate, so that the connecting member 20 translates under the drive of the transmission structure 2 to perform translational pushing and pulling of the door body 300 relative to the front sealing door 200 to realize the opening and closing of the door body 300.

[0083] In some embodiments, referring to Figure 2 and Figure 3As shown, for example, the door body 300 can be rotatably connected to the front sealing door 200 via a hinge 400. In this way, when the first driving member 11 drives the first gear group 12 to rotate, the second gear group 21 can rotate synchronously under the drive of the first gear group 12, and drive the connecting member 20 to rotate, thereby realizing the rotation of the door body 300 relative to the front sealing door 200, so that the door body 300 can be opened and closed, which is easy to use and saves the space required for the opening and closing process of the door body 300.

[0084] In some embodiments, reference Figure 2 and Figure 3 As shown, the hinge 400 includes two hinge arms 401, which are arranged at intervals in the rotation direction of the door body 300, and the connecting member 20 is located between the two hinge arms 401. Figure 2 and Figure 3 The ZZ direction is shown.

[0085] This arrangement makes reasonable use of the structure of the hinge 400 and arranges the connecting member 20 between the two hinge arms 401, which saves the space occupied by the connecting member 20 to a certain extent and ensures the overall aesthetics.

[0086] In some embodiments, reference Figures 4 to 6 As shown, the second gear set 21 includes a first gear 211, the first gear 211 is located on one side of the first gear set 12, the locking member 3 is located on the side of the first gear 211 away from the first gear set 12, and the locking member 3 can move toward the direction close to the first gear set 12 to lock the first gear 211 with the first gear set 12, or move toward the direction away from the first gear set 12 to unlock the first gear 211 and the first gear set 12.

[0087] In this way, the locking member 3 moves toward or away from the first gear set 12, thereby achieving locking or unlocking between the first gear 211 and the first gear set 12. The locking and unlocking process of the first gear 211 and the first gear set 12 is simple and easy to operate.

[0088] In some embodiments, reference Figures 4 to 7 As shown, the locking member 3 has a first locking portion 31 , the first gear 211 has an avoidance hole 2111 for the first locking portion 31 to pass through, and the first gear set 12 has a second locking portion 1232 that can be locked with the first locking portion 31 .

[0089] With such a setting, when it is necessary to lock the first gear 211 and the first gear set 12, the locking member 3 is moved toward the direction close to the first gear set 12, passes through the avoidance hole 2111, and the first locking portion 31 and the second locking portion 1232 are locked together. And when it is necessary to unlock the first gear 211 and the first gear set 12, the locking member 3 is moved away from the first gear set 12, and the first locking portion 31 is disengaged from the second locking portion 1232, which is convenient to use.

[0090] In some embodiments, referring to Figure 6 and Figure 7 as shown, the first locking portion 31 includes a claw extending toward the first gear set 12, and the second locking portion 1232 includes a card slot that can be engaged with the claw in a matching manner.

[0091] Exemplarily, the locking of the first gear 211 and the first gear set 12 can be achieved by the insertion and cooperation of the claw in the card slot, and the unlocking of the first gear 211 and the first gear set 12 can be achieved by the removal of the claw from the card slot. This also makes the locking and unlocking processes of the first gear 211 and the first gear set 12 simple, and the efficiency during locking and unlocking is relatively high.

[0092] Of course, in some other embodiments, the first locking portion 31 can also be, for example, a clamping groove, and the second locking portion 1232 can be a clamping arm that can extend into the clamping groove to achieve the locking or unlocking of the first locking portion 31 and the second locking portion 1232, thereby achieving the locking or unlocking of the first gear 211 and the first gear set 12.

[0093] In addition, the locking member 3 may not be disposed on one side of the first gear 211. For example, the locking member 3 can be disposed above the first gear 211 and the first gear set 12. For example, the first locking portion 31 includes a plurality of clamping claws arranged at intervals, and the plurality of clamping claws can move toward each other to clamp and lock the first gear 211 and the first gear set 12, or move away from each other to release the clamping of the first gear 211 and the first gear set 12.

[0094] In some embodiments, referring to Figure 6 and Figure 7 as shown, there are at least two first locking portions 31, and the at least two first locking portions 31 are arranged at intervals along the circumferential direction of the locking member 3. There are at least two second locking portions 1232, and they are arranged in one-to-one correspondence with the first locking portions 31.

[0095] With such a setting, the first locking portion 31 and the second locking portion 1232 can be locked from different positions in the circumferential direction of the locking member 3, so that the locking effect between the first locking portion 31 and the second locking portion 1232 can be improved to a certain extent. Furthermore, the locking effect between the first gear 211 and the first gear set 12 is improved, making the door body 300 have good stability during the opening and closing process.

[0096] In some embodiments, referring to Figures 4 to 8 As shown, one side of the first gear set 12 facing the first gear 211 has a protruding portion 1231 protruding in the direction of the first gear 211. The outer contour of the protruding portion 1231 is projected on the outer contour area of the first gear 211, and the second locking portion 1232 is arranged on the protruding portion 1231.

[0097] By setting the protruding portion 1231 and arranging the second locking portion 1232 on the protruding portion 1231 in this way, the structural strength of the first gear set 12 can be further ensured, and the stability when the first locking portion 31 and the second locking portion 1232 lock the first gear 211 and the first gear set 12 together can be improved to a certain extent. By making the projection of the outer contour of the protruding portion 1231 on the first gear 211 located within the outer contour area of the first gear 211, while ensuring the convenient locking of the first locking portion 31 and the second locking portion 1232, the situation of interference with other surrounding components can be avoided.

[0098] In some embodiments, referring to Figures 4 to 13 As shown, the driving mechanism 10 further includes a second driving member 4, and the second driving member 4 is used to drive the locking member 3 to move towards the direction close to the first gear set 12 or move towards the direction away from the first gear set 12.

[0099] Exemplarily, for example, the locking member 3 can be driven by the second driving member 4 to move towards the direction close to the first gear set 12, and the first gear 211 and the first gear set 12 can be locked together by the locking member 3, so that the first gear 211 and the first gear set 12 can rotate synchronously under the drive of the first driving member 11, and the connecting member 20 can drive the door body 300 to open and close relative to the front sealing door 200. For example, the locking member 3 can also be driven by the second driving member 4 to move towards the direction away from the first gear set 12, and the first gear 211 and the first gear set 12 can be unlocked by the locking member 3. This can improve the convenience when the first gear 211 and the first gear set 12 are locked and unlocked.

[0100] In some embodiments, referring to Figures 4 to 8As shown, the second driving member 4 includes a pushing structure 41 and an intermediate member 42. The intermediate member 42 is located on the side of the locking member 3 away from the first gear set 12. The intermediate member 42 is used to push the locking member 3 in the direction approaching the first gear set 12 under the thrust of the pushing structure 41, so as to lock the first gear 211 and the first gear set 12 together.

[0101] That is to say, by controlling the operation of the pushing structure 41, the pushing structure 41 generates a thrust on the intermediate member 42 in the direction approaching the first gear set 12, and the intermediate member 42 pushes the locking member 3 in the direction approaching the first gear set 12, so as to lock the first gear 211 and the first gear set 12 together, and the locking process is simple.

[0102] Exemplarily, with reference to Figure 4 As shown, a support shaft 13 is also fixedly connected to the first driving member 11. At least the intermediate member 42 and the first gear 211 are sleeved on the outer periphery of the support shaft 13, and the intermediate member 42 can push the locking member 3 to reciprocate along the axial direction of the support shaft 13 under the thrust of the pushing structure 41, so that the locking member 3 locks the first gear 211 and the first gear set 12. Exemplarily, the support shaft 13 can support the intermediate member 42 and the first gear 211 to a certain extent.

[0103] Exemplarily, the pushing structure 41 can include, for example, an electric push rod, a driving cylinder, a driving oil cylinder, etc.

[0104] In some embodiments, with reference to Figure 6 and Figure 7 As shown, the second driving member 4 further includes an elastic member 43. The elastic member 43 is disposed between the locking member 3 and the first gear 211, and the elastic force direction of the elastic member 43 is the same as the moving direction of the intermediate member 42. The locking member 3 can move in the direction away from the first gear set 12 under the elastic force of the elastic member 43 when the thrust disappears, so as to unlock the first gear 211 and the first gear set 12. Among them, the moving direction of the intermediate member 42 is specifically Figure 4 and Figure 6 the X-X direction shown.

[0105] That is to say, when it is necessary to move the locking member 3 in the direction away from the first gear set 12 to unlock the first gear 211 and the first gear set 12, only the thrust of the pushing structure 41 needs to be removed. At this time, the locking member 3 can move in the direction away from the first gear set 12 under the elastic force of the elastic member 43, so as to unlock the first gear 211 and the first gear set 12. This can improve the convenience of the locking member 3 when it rebounds to a certain extent, thereby improving the convenience of unlocking the first gear 211 and the first gear set 12, and the unlocking efficiency is high.

[0106] Exemplarily, the elastic member 43 can be, for example, a spring, an elastic rope, etc.

[0107] In some embodiments, as shown in Figures 4 to 7 the middle member 42 has a fitting step 421 protruding in the direction towards the locking member 3, the locking member 3 has a fitting portion 32 into which the fitting step 421 can be inserted, and at least part of the step surface of the fitting step 421 abuts against the fitting portion 32.

[0108] With such a setting, the stability and reliability during the cooperation between the locking member 3 and the middle member 42 can be improved to a certain extent, which is beneficial to improving the locking effect between the first gear 211 and the first gear set 12, so that when the first driving member 11 operates, the rotational stability of the first gear 211 and the first gear set 12 is good, and further the stability and reliability of the opening and closing of the door body 300 are improved.

[0109] Exemplarily, the fitting portion 32 can be, for example, a fitting hole. Among them, the fitting hole can be, for example, a through hole or a blind hole.

[0110] In some embodiments, as shown in Figures 4 to 7 there is a abutting and fitting surface 44 between the pushing structure 41 and the middle member 42, the pushing direction of the pushing structure 41 on the middle member 42 is perpendicular to the moving direction of the locking member 3, and in the direction of the pushing force of the pushing structure 41 on the middle member 42, the abutting and fitting surface 44 extends obliquely away from the locking member 3. Among them, the moving direction of the locking member 3 is specifically Figure 4 and Figure 6 the X-X direction shown in Figure 6 and Figure 7 the one-way arrow C direction shown in

[0111] That is to say, when the pushing structure 41 applies a pushing force in the C direction to the middle member 42, due to the setting of the abutting and fitting surface 44, the middle member 42 will be pushed to move towards the direction close to the first gear set 12, so that the locking member 3 moves and locks the first gear 211 and the first gear set 12.

[0112] Through the above setting, while the pushing structure 41 can push the locking member 3 to lock the first gear 211 and the first gear set 12, the fitting and abutting area between the pushing structure 41 and the middle member 42 can be increased to a certain extent, the stability of the fitting and abutting between the pushing structure 41 and the middle member 42 is improved, and thus the stability of the locking member 3 moving towards the direction close to the first gear set 12 is improved, making the locking of the first gear 211 and the first gear set 12 reliable and stable.

[0113] Exemplarily, a butt joint mating surface 44 can be provided at corresponding positions of the pushing structure 41 and the middle member 42, or the butt joint mating surface 44 can be provided on one of the pushing structure 41 and the middle member 42. Refer to Figures 4 to 7 As shown, the pushing structure 41 includes a slider 411, and the butt joint mating surface 44 can be provided on the slider 411, for example.

[0114] In some embodiments, refer to Figures 4 to 7 As shown, the second gear set 21 further includes a second gear 212. The first gear 211 is located on one side of the first gear set 12. The second gear 212 meshes with the first gear 211, and the connecting member 20 is connected to the second gear 212.

[0115] With such a setting, when the first gear 211 and the first gear set 12 are locked, the first gear set 12 rotates under the driving action of the first driving member 11 and drives the first gear 211 to rotate synchronously. Since the second gear 212 meshes with the first gear 211, the second gear 212 rotates synchronously with the first gear 211, and drives the connecting member 20 to open and close the door body 300 relative to the front sealing door 200.

[0116] In some embodiments, the door lock device 100 further includes a controller. Refer to Figures 5 to 8 As shown, an angular velocity sensor 5 is provided on the second gear set 21 or the connecting member 20; the angular velocity sensor 5 and the second driving member 4 are respectively electrically connected to the controller. The angular velocity sensor 5 is used to detect the angular velocity of the connecting member 20. The controller is used to control the second driving member 4 to drive the first gear 211 and the first gear set 12 to unlock when the angular velocity is zero.

[0117] Exemplarily, when the angular velocity is zero, it means that the connecting member 20 stops rotating, that is, the door body 300 is stationary relative to the front sealing door 200. At this time, the second driving member 4 can be used to drive the first gear 211 to move away from the first gear set 12 so as to unlock the first gear 211 and the first gear set 12. In this way, the power transmission between the first gear 211 and the first gear set 12 is blocked, and the user can still switch to manual operation to open and close the door body 300.

[0118] Wherein, the door body 300 being stationary can also be that other structures outside the laundry treatment device are blocked on the downstream side of the rotation direction of the door body 300, so that the door body 300 cannot continue to rotate under the driving action of the first driving member 11. To a certain extent, this avoids the situation that the door body 300 continues to rotate and collides with other structures and is damaged, and provides a certain degree of protection for the door body 300 and the like.

[0119] It should be noted that the controller may be a separate controller on the door lock device 100, or may also be the main controller of the laundry treatment device.

[0120] Referring to Figures 4 to 13 As shown, one end of the connecting member 20 has a connecting shaft 201. The second gear set 21 is sleeved on the outer periphery of the connecting shaft 201 and is fixed to the connecting shaft 201. For example, the angular velocity sensor 5 can be connected to the connecting shaft 201.

[0121] Exemplarily, when the pushing structure 41 includes an electric push rod, in the initial state, the electric push rod is not powered on, and the first gear 211 and the first gear set 12 are in an unlocked state. By powering on the electric push rod, the electric push rod pushes the locking member 3 towards the direction close to the first gear set 12 to lock the first gear 211 and the first gear set 12 together. Thus, when the first driving member 11 drives the first gear set 12 to rotate, the first gear 211 can rotate synchronously with the first gear set 12 and drive the door body 300 to rotate for opening and closing. When the angular velocity is zero, by retracting and powering off the electric push rod, at this time, the locking member 3 can move towards the direction away from the first gear set 12 under the action of the elastic member 43 to unlock the first gear 211 and the first gear set 12, and control the first driving member 11 to stop working.

[0122] In some embodiments, referring to Figures 5 to 13 As shown, the driving mechanism 10 further includes a mounting housing 6. The first gear set 12 and the second gear set 21 are located inside the mounting housing 6. The first driving member 11 and the second driving member 4 are located outside the mounting housing 6. The mounting housing 6 has a first avoidance hole for the cooperation of the first driving member 11 and the first gear set 12, a second avoidance hole for the cooperation of the second driving member 4 and the locking member 3, and a third avoidance hole for the connection of the second gear set 21 and the connecting member 20.

[0123] With such a setting, to a certain extent, the modularization of structures such as the first gear set 12 and the second gear set 21 is realized through the mounting housing 6, which facilitates the connection between the driving mechanism 10 and the front sealing door 200, and the assembly is more convenient and rapid.

[0124] At the same time, by arranging the first gear set 12 and the second gear set 21 inside the mounting housing 6, the first gear set 12 and the second gear set 21 can be protected to avoid the situation of being bumped and damaged by other structures. In addition, the settings of the first avoidance hole, the second avoidance hole, and the third avoidance hole facilitate the cooperation of the first driving member 11 and the first gear set 12, the cooperation of the second driving member 4 and the locking member 3, and the connection of the second gear set 21 and the connecting member 20.

[0125] Exemplarily, referring to Figures 5 to 10As shown, the installation housing 6 includes a housing body 61 and a cover body 62. The cover body 62 can be hermetically covered on the housing body 61, and the first gear set 12 and the second gear set 21 are accommodated in the space formed by enclosing the housing body 61 and the cover body 62.

[0126] In some embodiments, referring to Figures 4 to 13 As shown, the first driving member 11 includes a driving motor 111 and a speed reducer 112. The speed reducer 112 is connected to the output shaft of the driving motor 111. The first gear set 12 includes a third gear 121, a fourth gear 122, and a fifth gear 123. The third gear 121 is connected to the speed reducer 112. The fourth gear 122 meshes with the third gear 121, and the pitch circle diameter of the fourth gear 122 is greater than the pitch circle diameter of the third gear 121. The fifth gear 123 meshes with the fourth gear 122, and the pitch circle diameter of the fifth gear 123 is greater than the pitch circle diameter of the fourth gear 122. The locking member 3 is used to lock the fifth gear 123 and the second gear set 21 together or unlock the fifth gear 123 and the second gear set 21.

[0127] Specifically, referring to Figure 4 and Figure 6 As shown, specifically, the first gear 211 can be locked together with or unlocked from the fifth gear 123.

[0128] Through the above arrangement, through the cooperation of the speed reducer 112, the third gear 121, the fourth gear 122, and the fifth gear 123, the output speed of the driving motor 111 can be reduced to a certain extent, so that the output speed of the first gear set 12 can be flexibly adjusted, improving the stability of the first gear set 12 during rotation. Thereby, the stability of the second gear set 21 and the connecting member 20 during rotation is improved, and further, the stability of the rotation of the door body 300 is better, and the noise during the opening and closing rotation of the door body 300 can be reduced to a certain extent, enhancing the user experience.

[0129] Referring to Figure 4 and Figure 6 As shown, the fourth gear 122 includes a first sub-gear 1221 and a second sub-gear 1222 connected to each other. Among them, the first sub-gear 1221 meshes with the third gear 121, and the pitch circle diameter of the first sub-gear 1221 is greater than the pitch circle diameter of the third gear 121. The second sub-gear 1222 meshes with the fifth gear 123. Among them, the fact that the pitch circle diameter of the fifth gear 123 is greater than the pitch circle diameter of the fourth gear 122 specifically means that the pitch circle diameter of the fifth gear 123 is greater than the pitch circle diameter of the second sub-gear 1222.

[0130] Exemplarily, for example, the above-mentioned controller can be electrically connected to the drive motor 111 and is used to control the working state of the drive motor 111 (such as starting to work, stopping working, etc.), thereby realizing the automatic opening and closing of the door body 300 and saving manpower.

[0131] In some embodiments, referring to Figure 2 , Figure 3 , Figure 12 and Figure 13 as shown, the driving mechanism 10 is arranged on the side of the front sealing door 200 facing away from the door body 300, and an avoidance notch 2001 is formed on the front sealing door 200 for the connector 20 to extend and move.

[0132] That is to say, the driving mechanism 10 is placed in the cabinet 500 of the laundry treatment device, which can not only protect the driving mechanism 10 to a certain extent, but also make the surface of the front sealing door 200 more beautiful and flat. At the same time, the setting of the avoidance notch 2001 provides an avoidance space for the matching connection of the connector 20 and the door body 300, ensuring the smooth connection of the connector 20 and the door body 300.

[0133] Of course, in some other embodiments, the driving mechanism 10 can also be arranged on the side of the front sealing door 200 facing the door body 300.

[0134] In some embodiments, referring to Figures 11 to 13 as shown, the door lock device 100 further includes a backplane connection seat 7. The backplane connection seat 7 is detachably installed on the side of the front sealing door 200 facing away from the door body 300, and the driving mechanism 10 is installed on the backplane connection seat 7.

[0135] With this setting, the driving mechanism 10 is installed and supported on the front sealing door 200 through the backplane connection seat 7, and at the same time, the driving mechanism 10 is detachably connected to the front sealing door 200, which is convenient for assembly and has high assembly efficiency. Moreover, when one of the driving structure 1 and the front sealing door 200 is damaged, only the damaged part needs to be replaced, which is convenient for maintenance or replacement, avoiding the scrapping of the whole of the front sealing door 200 and the driving mechanism 10, and saving the maintenance and use cost.

[0136] When specifically implemented, the connecting shaft 201 can be rotatably connected to the backplane connection seat 7, so that while the connecting shaft 201 rotates together with the second gear set 21 and the connector 20 to open and close the door body 300, the backplane connection seat 7 can also support the connecting shaft 201.

[0137] In some embodiments, referring to Figures 4 to 11As shown, the connecting member 20 includes a first connecting rod 202 and a second connecting rod 203. One end of the first connecting rod 202 is connected to the transmission structure 2, one end of the second connecting rod 203 is rotatably connected to the first connecting rod 202, and the other end of the second connecting rod 203 is rotatably connected to the door body 300.

[0138] This arrangement makes it easy for the transmission structure 2 to drive the first connecting rod 202 and the second connecting rod 203 to move under the drive of the driving structure 1, and to move the door body 300 to achieve opening and closing of the door body 300 relative to the front sealing door 200, making the door body 300 more flexible when opening and closing.

[0139] Moreover, such an arrangement makes it convenient to arrange the driving mechanism 10 on the side of the front sealing door 200 away from the door body 300, so that part of the first connecting rod 202 and the second connecting rod 203 extend from the avoidance notch 2001 on the front sealing door 200 to the outside of the front sealing door 200, so as to more flexibly drive the movement of the door body 300 and realize the opening and closing of the door body 300.

[0140] Continue to refer to Figures 1 to 15 As shown, this embodiment provides a clothes processing device, including a door body 300 , a front sealing door 200 and a door locking device 100 .

[0141] By connecting the door lock device 100 between the door body 300 and the front sealing door 200 , the door body 300 can be closed or opened relative to the front sealing door 200 .

[0142] The door lock device 100 in this embodiment has the same structure and implementation principle as the door lock device 100 provided in the above embodiment, and can bring the same or similar technical effects, and reference may be made to the description of the above embodiment.

[0143] Other technical features are the same as those of the above embodiments and can bring the same or similar technical effects, which will not be described here one by one. Please refer to the description of the above embodiments for details.

[0144] Continue to refer to Figures 1 to 15 As shown, this embodiment further provides a door opening and closing control method for a clothes processing device, which can be executed by all or part of the clothes processing device provided by the above embodiment, and the method specifically includes:

[0145] S101: The driving structure 1 and the transmission structure 2 are locked together by the locking member 3.

[0146] Specifically, when the driving structure 1 and the transmission structure 2 are locked by the locking member 3 , the driving structure 1 can drive the transmission structure 2 to move.

[0147] S102: Drive the transmission structure 2 to move through the drive structure 1, so that the connecting member 20 moves driven by the transmission structure 2, and the door body 300 closes relative to the front sealing door 200 or the door body 300 opens relative to the front sealing door 200.

[0148] In this way, the drive structure 1 drives the transmission structure 2, and the transmission structure 2 drives the connecting member 20 to move, realizing the opening and closing of the door body 300, which provides great convenience for users and is more labor-saving for users, greatly improving the user experience.

[0149] The clothing treatment device in this embodiment has the same structure and implementation principle as the clothing treatment device provided in the above embodiment, and can bring the same or similar technical effects, and can refer to the description of the above embodiment.

[0150] Further, after the step of driving the transmission structure 2 to move through the drive structure 1, the method further includes:

[0151] S103: Detect the angular velocity of the connecting member 20.

[0152] By detecting the angular velocity of the rotation of the connecting member 20, it is convenient to obtain the rotational angular velocity of the connecting member 20, and thus obtain the angular velocity of the rotation of the door body 300 relative to the front sealing door 200.

[0153] S104: When the angular velocity is zero, make the second driving member 4 drive the second gear set 21 and the first gear set 12 to unlock.

[0154] Among them, when the angular velocity is zero, the door body 300 is stationary relative to the front sealing door 200. At this time, the second driving member 4 can drive the first gear 211 to move away from the first gear set 12, so that the first gear 211 and the first gear set 12 are unlocked. In this way, the power transmission between the first gear 211 and the first gear set 12 is blocked, and the user can still switch to manual operation to open and close the door body 300.

[0155] When the angular velocity is not zero, it means that the door body 300 is in a rotating state relative to the front sealing door 200 to realize the opening and closing of the door body 300.

[0156] Refer to Figure 15 As shown, by way of example, a specific example is used to further illustrate the door opening and closing control method of the clothing treatment device:

[0157] Taking the second driving member 4 including a pushing structure 41 and an elastic member 43, the pushing structure 41 including an electric push rod, and the first driving member 11 including a driving motor 111 as an example. Assume that in the initial state, the door body 300 is closed relative to the front sealing door 200, the electric push rod is not powered on, and the first gear set 12 and the second gear set 21 are unlocked.

[0158] Specifically, when it is necessary to open the door body 300, for example, the lock hook 301 of the electromagnetic spring lock can be disengaged from the lock groove 2002 first through the main controller of the laundry treatment device. At this time, the door body 300 can rotate a preset angle relative to the front sealing door 200. For example, the door body 300 rotates and opens by 0°-4°. That is to say, when opening the door body 300, the electromagnetic spring lock acts to open the door body by 0°-4°.

[0159] Then, by controlling the electric push rod to be energized, the first gear set and the second gear set are locked, and the driving motor is controlled to work. Specifically, the electric push rod pushes out the locking member 3 to lock the first gear set 12 and the second gear set 21 together, so that the first gear set 12 drives the second gear set 21 to rotate under the drive of the driving motor 111, and the connecting member 20 rotates to make the door body 300 rotate away from the front sealing door 200, so that the door body 300 continues to rotate and open. For example, the door body 300 then rotates until the included angle with the front sealing door 200 is 150° and then stops.

[0160] Exemplarily, during the process of the door body 300 rotating and opening, the angular velocity sensor 5 detects the angular velocity of the connecting member 20 driving the door body 300 to rotate. For example, when the angular velocity detected by the angular velocity sensor 5 is zero, it means that the door body is blocked by an object or a person (such as blocked on the side of the door body 300 away from the front sealing door 200), resulting in the front sealing door 200 being unable to continue rotating. At this time, the electric push rod retracts and is powered off (the electric push rod retracts in the direction opposite to the C direction shown in Figure 6 and Figure 7 ), and the locking member 3 moves under the action of the spring. Specifically, the locking member 3 moves away from the first gear set 12, the first gear set and the second gear set are unlocked, and the driving motor stops working, so as to stop the automatic opening of the door body and switch to manual door opening. When the angular velocity detected by the angular velocity sensor 5 is not zero, it means that there is no obstacle outside the door body. Keep the electric push rod energized, the first gear set 12 and the second gear set 21 are locked, the door body 300 automatically opens, and the door body 300 rotates and opens to 150° and then stops.

[0161] Similarly, during the process of closing the door body 300, when the detection result of the angular velocity sensor 5 is zero, the second driving member 4 also makes the locking member 3 move to unlock the second gear set 21 from the first gear set 12, so that the door body 300 stops rotating. At this time, the user can manually operate to make the door body 300 continue to rotate and close, realizing the flexible switching between the automatic opening and closing and the manual opening and closing of the door body 300.
