DETAILED DESCRIPTION

[0058] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0059] In the following description, many specific details are set forth to facilitate a full understanding of 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; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0060] Reference Figures 1 to 11 As 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 a washing machine, a dryer, a washing and drying machine, or a clothing processing cabinet.

[0061] 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.

[0062] The door lock device 100 includes a driving mechanism 10 and a connecting member 20 , and the driving mechanism 10 is arranged on the front sealing door 200 .

[0063] The driving mechanism 10 includes a magnetic coupling structure 1, and the connecting member 20 is connected between the door body 300 and the magnetic coupling structure 1. The connecting member 20 can move under the drive of the magnetic coupling structure 1 to close the door body 300 relative to the front sealing door 200, or to open the door body 300 relative to the front sealing door 200.

[0064] In specific implementation, the magnetic coupling structure 1 drives the connecting member 20 to move. Since the driving mechanism 10 is arranged on the door body 300, and the connecting member 20 is connected between the door body 300 and the magnetic coupling structure 1, the opening and closing of the door body 300 relative to the front sealing door 200 can be realized, so as to open and close the clothing delivery port, facilitating the user to flexibly adjust the opening and closing of the door body 300 according to actual usage requirements, and to a certain extent avoiding the situation of the user manually operating to open and close the door body 300, saving manpower, and thus greatly improving the user experience.

[0065] Exemplarily, taking the clothing 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 work starts, for example, when drying for ten minutes, the magnetic coupling structure 1 drives the connecting member 20 to drive the door body 300 to move, opening the door body 300 to open the clothing delivery port, so that the high-temperature and humid air in the clothing treatment cylinder 501 can be discharged from the clothing delivery port, accelerating the air circulation in the clothing treatment cylinder 501 and improving the drying efficiency of the clothing. For example, one minute after the door body 300 is opened, the magnetic coupling structure 1 drives the connecting member 20 to drive the door body 300 to move to close the door body 300 again to avoid the entry of external dust or animals into the clothing treatment cylinder 501 during the drying process. For example, when the drying is completed, the magnetic coupling structure 1 drives the connecting member 20 to drive the door body 300 to move to open the door body 300, facilitating the user to take out the dried clothes. For example, ten minutes after the door body 300 is opened, the door body 300 is closed again by the magnetic coupling structure 1 to further avoid the entry of external dust or animals into the clothing treatment cylinder 501 during the drying process, ensuring the cleanliness inside the cabinet 500 and providing safety protection for animals and the like.

[0066] Among them, during the whole drying process, the clothing delivery port can be opened and closed multiple times, thereby further accelerating the drying efficiency of the clothing.

[0067] In specific implementation, for example, 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 magnetic coupling structure 1, as long as the connecting member 20 can be driven by the magnetic coupling structure 1 to move to realize the closing of the door body 300 relative to the front sealing door 200, or the opening of the door body 300 relative to the front sealing door 200.

[0068] Exemplarily, referring to Figure 2As shown, for example, a locking hook 301 can be provided on the door body 300, and a locking groove 2002 can be provided on the front sealing door 200. For example, the locking hook 301 can be an electromagnetic elastic locking hook. Through the cooperation between the electromagnetic elastic locking hook and the locking groove 2002, elastic locking between the front sealing door 200 and the door body 300 is achieved. For example, the door locking device 100 and the locking hook 301 can be oppositely arranged on the laundry treating device.

[0069] Among them, the laundry treating device includes a main controller. The main controller can be electrically connected to the electromagnetic elastic locking hook, for example, and is used to control the cooperation between the electromagnetic elastic locking hook and the locking groove 2002, as well as the disengagement cooperation between the electromagnetic elastic locking hook and the locking groove 2002.

[0070] Exemplarily, when it is necessary to open the door body 300, for example, the main controller can be made to disengage the electromagnetic elastic locking hook from the locking groove 2002, so that the door body 300 is disengaged from the front sealing door 200. Then, the magnetic coupling structure 1 is made to drive the connecting member 20 to move, so that the door body 300 moves in a direction away from the front sealing door 200 to open the door body 300; when it is necessary to close the door body 300, the magnetic coupling structure 1 is made to drive the connecting member 20 to move, so that the door body 300 moves in a direction close to the front sealing door 200 to close the door body 300. And when the door body 300 is re-closed, the electromagnetic elastic locking hook is locked with the locking groove 2002 to ensure the locking effect of the door body 300.

[0071] Specifically, the connecting member 20 can be a connecting rod, a connecting block, etc., for example.

[0072] The door lock device provided in this embodiment is configured by arranging a driving mechanism 10 and a connecting member 20. The driving mechanism 10 is disposed on one of the front door 200 and the door body 300 of the laundry treatment device. The driving mechanism 10 includes a magnetic coupling structure 1. The connecting member 20 is connected between the other of the front door 200 and the door body 300 and the magnetic coupling structure 1. By enabling the connecting member 20 to move under the drive of the magnetic coupling structure 1, the door body 300 can be closed relative to the front door 200 or the door body 300 can be opened relative to the front door 200. That is to say, through the cooperation of the magnetic coupling structure 1 and the connecting member 20, the opening and closing of the door body 300 relative to the front door 200 can be achieved, 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 drum 501, the magnetic coupling structure 1 is made to drive the connecting member 20 to move so that the door body 300 can be opened relative to the front door 200, thereby avoiding the generation of peculiar smell and bacteria in the laundry drum 501 to a certain extent. For another example, when drying 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 drum 501 to improve the drying efficiency of the clothes. For yet another example, the magnetic coupling structure 1 can be used to drive the connecting member 20 to move so that the door body 300 can be closed relative to the front door 200, thereby preventing dirt, animals, etc. from entering the laundry drum 501 to a certain extent, ensuring the cleanliness of the laundry drum 501 and providing safety protection for animals, etc.

[0073] In some embodiments, referring to Figure 4 and Figure 5 as shown, the driving mechanism 10 further includes a first driving member 2. The magnetic coupling structure 1 includes a magnetic force output member 11 and a magnetic force receiving member 12. The magnetic force receiving member 12 is disposed opposite to the magnetic force output member 11, and the magnetic force receiving member 12 can be magnetically coupled with the magnetic force output member 11. The magnetic force output member 11 is connected to the first driving member 2, and the connecting member 20 is connected to the magnetic force receiving member 12. The first driving member 2 is used to drive the magnetic force output member 11 to move so as to drive the connecting member 20 to move when the magnetic force receiving member 12 is magnetically coupled with the magnetic force output member 11.

[0074] In this way, the magnetic coupling structure 1 is made to include the magnetic force output member 11 and the magnetic force receiving member 12. At the same time, by controlling the operation of the first driving member 2 to drive the magnetic force output member 11 to move, when the magnetic force receiving member 12 is magnetically coupled with the magnetic force output member 11, the magnetic force output member 11 will move synchronously under the drive of the magnetic force receiving member 12 and drive the connecting member 20 to move to achieve the opening and closing of the door body 300.

[0075] Exemplarily, in the initial state, the magnetic force output member 11 and the magnetic force receiving member 12 are in a magnetic coupling state. At this time, an electromagnetic field will be formed between the magnetic force receiving member 12 and the magnetic force output member 11. In this way, when the first driving member 2 drives the magnetic force receiving member 12 to move, the magnetic force receiving member 12 and the magnetic force output member 11 can move synchronously. For example, when the first driving member 2 drives the magnetic force output member 11 to rotate, the magnetic force receiving member 12 will rotate synchronously with the magnetic force output member 11, for example, rotate synchronously with the magnetic force output member 11 at the same frequency and in the same direction.

[0076] Exemplarily, when the magnetic force output member 11 contacts the magnetic force receiving member 12, or the distance between the magnetic force output member 11 and the magnetic force receiving member 12 is less than or equal to a preset distance (this preset distance is the critical value at which the magnetic force output member 11 and the magnetic force receiving member 12 can perform magnetic coupling. If it is greater than this preset distance, the magnetic force output member 11 and the magnetic force receiving member 12 cannot perform magnetic coupling), the magnetic force output member 11 and the magnetic force receiving member 12 are magnetically coupled, and the two are in a power coupling state, so that the two can rotate synchronously.

[0077] When the distance between the magnetic force output member 11 and the magnetic force receiving member 12 is greater than the above preset distance, no magnetic force can be generated between the magnetic force output member 11 and the magnetic force receiving member 12. At this time, the magnetic force output member 11 and the magnetic force receiving member 12 are decoupled, and the two are in a power release state, and the magnetic force receiving member 12 will not rotate synchronously with the magnetic force output member 11.

[0078] In this way, when it is necessary to open the door body 300, the first driving member 2 is used to drive the magnetic force output member 11 to move in a preset direction, so that the door body 300 opens relative to the front sealing door 200; and when it is necessary to close the door body 300, the first driving member 2 is used to drive the magnetic force output member 11 to move in a direction opposite to the preset direction, so that the door body 300 closes relative to the front sealing door 200.

[0079] Exemplarily, the magnetic force output member 11 and the magnetic force receiving member 12 can be permanent magnets, for example. Of course, the magnetic force output member 11 and the magnetic force receiving member 12 can also be electromagnetic coils, or electromagnets, etc.

[0080] Referring to Figures 4 to 9 As shown, the first driving member 2 includes a driving motor 21 and a speed reducer 22 connected to the output shaft of the driving motor 21, and the speed reducer 22 is connected to the magnetic force output member 11. When the driving motor 21 works, the magnetic force output member 11 is driven to move through the speed reducer 22, thereby realizing the automatic opening and closing of the door body 300 and saving manpower.

[0081] In some embodiments, referring to Figure 4 and Figure 5As shown, the first driving member 2 is used to drive the magnetic force output member 11 to rotate around a rotating shaft. The magnetic force receiving member 12 is located on one axial side of the magnetic force output member 11 to drive the connecting member 20 to rotate under the magnetic force of the magnetic force output member 11.

[0082] With such an arrangement, the magnetic force output member 11 is rotated by the first driving member 2, and when the magnetic force output member 11 and the magnetic force receiving member 12 are magnetically coupled, the magnetic force receiving member 12 rotates synchronously with the magnetic force output member 11, thereby realizing the opening and closing of the door body 300, which is convenient for users and saves manpower.

[0083] In some embodiments, referring to Figure 2 and Figure 3 As shown, for example, the door body 300 can be rotatably connected to the front sealing door 200 through a hinge 400. In this way, when the first driving member 2 drives the magnetic force output member 11 to rotate, the door body 300 can rotate relative to the front sealing door 200, realizing the opening and closing of the door body 300, which is convenient to use and saves the space required for the opening and closing process of the door body 300.

[0084] In some embodiments, referring to Figure 2 and Figure 3 As shown, the above hinge 400 includes two hinge arms 401. The two hinge arms 401 are spaced apart in the rotation direction of the door body 300, and the connecting member 20 is located between the two hinge arms 401. Among them, the rotation direction of the door body 300 is specifically the Figure 2 and Figure 3 Z-Z direction shown.

[0085] With such an arrangement, the structure of the hinge 400 is reasonably utilized, and the connecting member 20 is arranged between the two hinge arms 401, saving the occupied space of the connecting member 20 to a certain extent and ensuring the overall aesthetics.

[0086] Of course, in some other embodiments, the first driving member 2 can also be used to drive the magnetic force output member 11 to translate, so as to drive the connecting member 20 to translate when the magnetic force receiving member 12 and the magnetic force output member 11 are magnetically coupled, and the connecting member 20 translates and pushes and pulls the door body 300 to realize the opening and closing of the door body 300.

[0087] In some embodiments, referring to Figure 4 and Figure 5 As shown, one end of the connecting member 20 has a connecting shaft 201. The magnetic force receiving member 12 is sleeved on the connecting shaft 201. The connecting shaft 201 is located on one side of the rotating shaft of the magnetic force output member 11 and is coaxially arranged with the rotating shaft of the magnetic force output member 11.

[0088] With such an arrangement, when the magnetic force receiving member 12 is magnetically coupled with the magnetic force output member 11, it is convenient to drive the magnetic force receiving member 12 to rotate synchronously under the drive of the first driving member 2, and drive the connecting member 20 to rotate, so as to open and close the door body 300. Moreover, by coaxially arranging the connecting shaft 201 with the rotating shaft of the magnetic force output member 11, while realizing the opening and closing of the door body 300, it is also possible to save the space for the rotation of the magnetic force receiving member 12 and the magnetic force output member 11 to a certain extent, avoid the interference between the door lock device 100 and other structures when the door body 300 is opened and closed, and is also beneficial to reducing the volume of the entire laundry treatment device.

[0089] In some embodiments, referring to Figures 4 to 7 as shown, an angle limiting structure 3 is further provided on the driving mechanism 10 or the connecting member 20. The angle limiting structure 3 is used to limit the rotation angle of the connecting member 20 to control the opening and closing angle of the door body 300.

[0090] With such an arrangement, the opening and closing of the door body 300 within a preset angle range are realized, and to a certain extent, the situation that the door body 300 is overly opened or closed and interferes with or collides with other structures outside the door body 300 is avoided, and the door body 300 and the like are protected to a certain extent.

[0091] Exemplarily, for example, the rotation angle of the door body 300 relative to the front sealing door 200 can be between 0° and 150°.

[0092] In some embodiments, referring to Figures 4 to 9 as shown, the driving mechanism 10 further includes a second driving member 4, and the second driving member 4 is connected to the magnetic force output member 11. The second driving member 4 is used to drive the magnetic force output member 11 to move towards the direction close to the magnetic force receiving member 12, so that the magnetic force output member 11 and the magnetic force receiving member 12 are magnetically coupled, or used to drive the magnetic force output member 11 to move towards the direction away from the magnetic force receiving member 12, so that the magnetic force output member 11 and the magnetic force receiving member 12 are decoupled.

[0093] Wherein, when the second driving member 4 drives the magnetic force output member 11 to move towards the direction close to the magnetic force receiving member 12, so that the magnetic force output member 11 and the magnetic force receiving member 12 are magnetically coupled, it can be that the magnetic force output member 11 moves to contact the magnetic force receiving member 12, or the distance between the magnetic force output member 11 and the magnetic force receiving member 12 is less than or equal to a preset distance. Wherein, the preset distance is the critical distance at which the magnetic force output member 11 and the magnetic force receiving member 12 can be magnetically coupled.

[0094] By setting the second driving member 4, the magnetic force output member 11 is moved towards the direction close to the magnetic force receiving member 12, so as to reduce the distance between the magnetic force output member 11 and the magnetic force receiving member 12, thereby enabling the magnetic force coupling between the magnetic force output member 11 and the magnetic force receiving member 12. At this time, the magnetic force output member 11 and the magnetic force receiving member 12 are in a power coupling state, so that the magnetic force output member 11 can drive the magnetic force receiving member 12 to rotate under the drive of the first driving member 2, and the connecting member 20 drives the door body 300 to open and close relative to the front sealing door 200.

[0095] Exemplarily, when it is necessary to decouple the magnetic force output member 11 and the magnetic force receiving member 12, the second driving member 4 is used to move the magnetic force output member 11 in the direction away from the magnetic force receiving member 12, so as to increase the distance between the magnetic force output member 11 and the magnetic force receiving member 12, and make the distance greater than the above preset distance, realizing the decoupling of the magnetic force output member 11 and the magnetic force receiving member 12. At this time, the magnetic force output member 11 and the magnetic force receiving member 12 are in a power release state. Among them, when the magnetic force output member 11 and the magnetic force receiving member 12 are decoupled, the magnetic field between the magnetic force output member 11 and the magnetic force receiving member 12 is disconnected, and the magnetic force receiving member 12 will not drive the connecting member 20 to drive the door body 300 to open and close under the driving action of the magnetic force output member 11. At this time, for example, the door body 300 can be opened and closed manually, so that it is convenient to switch the opening and closing mode of the door body 300 according to actual use requirements, and the use is flexible and convenient.

[0096] Of course, in some other embodiments, the second driving member 4 can also be connected to the magnetic force receiving member 12, and the second driving member 4 is used to move the magnetic force receiving member 12 towards the direction close to or away from the magnetic force output member 11, so as to realize the magnetic force coupling or decoupling of the two.

[0097] In some embodiments, referring to Figure 4 and Figure 5 As shown, when the driving mechanism 10 further includes a second driving member 4, the above-mentioned angle limiting structure 3 is specifically arranged between the second driving member 4 and the magnetic force output member 11 to limit the rotation angle of the connecting member 20, thereby controlling the opening and closing angle of the door body 300.

[0098] Of course, in some other embodiments, the above-mentioned angle limiting structure 3 can also be arranged between the second driving member 4 and the magnetic force receiving member 12.

[0099] In some embodiments, referring to Figures 4 to 7As shown, the angle limiting structure 3 includes a first limiting portion 111 provided on the magnetic force output member 11 and a second limiting portion 41 provided on the second driving member 4. Among them, the first limiting portion 111 is an arc-shaped groove, and the arc-shaped groove extends along the circumferential direction of the magnetic force output member 11. The second limiting portion 41 extends into the arc-shaped groove and can reciprocate along the extending direction of the arc-shaped groove. Among them, the extending direction of the rotation axis of the magnetic force output member 11 is specifically Figure 4 the X-X direction shown in the figure.

[0100] Exemplarily, the size of the central angle corresponding to the arc-shaped side of the arc-shaped groove is the range of the rotation angle of the second limiting portion 41, that is, by adjusting the extending length of the above-mentioned arc-shaped side to adjust the size of the central angle, so that when the second limiting portion 41 reciprocates along the extending direction of the arc-shaped groove, the rotation angle range of the second limiting portion 41 can be adjusted, so that the door body 300 can be opened and closed within a preset angle range.

[0101] Exemplarily, referring to Figure 4 and Figure 5 shown in the figure, for example, an arc-shaped protrusion 112 protruding in the direction of the second driving member 4 can be provided on the magnetic force output member 11, and the arc-shaped groove can be provided on the arc-shaped protrusion 112. The arc-shaped protrusion 112 can be integrally formed with the magnetic force output member 11, for example.

[0102] Of course, in some other embodiments, the first limiting portion 111 can also be provided on the magnetic force receiving member 12. In addition, the second limiting portion 41 can also be an arc-shaped groove, the extending direction of the arc-shaped groove is the same as the rotation direction of the magnetic force output member 11, and the first limiting portion 111 extends into the arc-shaped groove and can reciprocate along the extending direction of the arc-shaped groove.

[0103] In some embodiments, referring to Figures 4 to 7 shown in the figure, the second driving member 4 includes a push rod that can reciprocate along the direction in which the magnetic force output member 11 and the magnetic force receiving member 12 move relative to each other. When the first limiting portion 111 is an arc-shaped groove, one end of the push rod forms the second limiting portion 41, and a stop portion 42 is provided on the side wall of the push rod to prevent the push rod from disengaging from the arc-shaped groove. Among them, the relative movement direction of the magnetic force output member 11 and the magnetic force receiving member 12 is specifically Figure 4 the X-X direction shown in the figure.

[0104] With such a setting, through the reciprocating push of the push rod, the relative movement between the magnetic force output member 11 and the magnetic force receiving member 12 is realized, so that the magnetic force output member 11 and the magnetic force receiving member 12 are magnetically coupled or decoupled. By setting the stop portion 42, to a certain extent, the stability of the cooperation between the push rod and the magnetic force output member 11 is ensured, so that the push rod can stably drive the magnetic force output member 11 to move, and the magnetic coupling and decoupling processes of the magnetic force output member 11 and the magnetic force receiving member 12 are stable and smooth, which is beneficial to improving the stability and efficiency of the opening and closing of the door body 300.

[0105] Referring to Figures 4 to 7 As shown, the stop portion 42 can be, for example, a stop groove formed on the outer side wall of the push rod. For example, the groove wall of the arc-shaped groove can extend into and be clamped in the stop groove to realize the connection between the push rod and the arc-shaped groove.

[0106] Of course, the stop portion 42 can also be a stop protrusion provided on the outer side wall of the push rod. There are two stop protrusions, and the two stop protrusions are arranged oppositely along the axial direction of the push rod, and the groove wall of the arc-shaped groove is clamped between the two stop protrusions.

[0107] Exemplarily, the second driving member 4 can be, for example, an electric push rod, a driving cylinder, a driving oil cylinder, etc.

[0108] In some embodiments, referring to Figure 4 and Figure 5 As shown, the magnetic force receiving member 12 and the second driving member 4 are located on the same side of the magnetic force output member 11 away from the first driving member 2. The angle limiting structure 3 is arranged between the end of the second driving member 4 facing the first driving member 2 and the magnetic force output member 11.

[0109] With such a setting, while the door body 300 can be opened and closed within a preset angle range, the space of the magnetic force receiving member 12 and the magnetic force output member 11 themselves can be effectively utilized. Thus, the occupied space of the magnetic force receiving member 12, the second driving member 4, the magnetic force output member 11 and the angle limiting structure 3 can be reduced to a certain extent, and further, the volume of the door lock device 100 can be reduced to a certain extent, which is beneficial to the miniaturization development of the laundry equipment.

[0110] In some embodiments, the door lock device 100 further includes a controller. Referring to Figure 5 As shown, an angular velocity sensor 5 is arranged on 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 magnetic force output member 11 and the magnetic force receiving member 12 to be decoupled when the angular velocity is zero.

[0111] Exemplarily, when the angular velocity is zero, it indicates that the connecting member 20 stops rotating, that is, the door body 300 is in a static state relative to the front sealing door 200. At this time, the second driving member 4 can be used to drive the magnetic force output member 11 to move away from the magnetic force receiving member 12, so that the magnetic force output member 11 and the magnetic force receiving member 12 are decoupled. In this way, the power transmission between the magnetic force output member 11 and the magnetic force receiving member 12 is blocked, and the user can still switch to manual operation to open and close the door body 300.

[0112] Among them, the static state of the door body 300 can also be, for example, that other objects outside the laundry treatment device are blocked on the downstream side in 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 2. To a certain extent, this avoids the situation where the door body 300 continues to rotate and collides with other structures and is damaged, providing a certain degree of protection for the door body 300 and the like.

[0113] It should be noted that the controller can be a separate controller on the door lock device 100, or it can also be the main controller of the laundry treatment device.

[0114] Exemplarily, for example, when the second driving member 4 is an electric push rod, in the initial state, the electric push rod is not powered on and the magnetic force output member 11 and the magnetic force receiving member 12 are magnetically coupled. When the angular velocity is zero, the electric push rod is powered on, and the electric push rod pushes the magnetic force output member 11 outwards to release the magnetic force from the magnetic force receiving member 12, and the first driving member 2 is controlled to stop working.

[0115] In some embodiments, referring to Figures 4 to 9 As shown, the driving mechanism 10 further includes a mounting housing 6. The magnetic force output member 11, the magnetic force receiving member 12, the first driving member 2 and the second driving member 4 are all arranged on the mounting housing 6, so that the driving mechanism 10 is connected to the front sealing door 200 through the mounting housing 6. A receiving groove 61 is provided on the mounting housing 6, and the second driving member 4 is located in the receiving groove 61.

[0116] With such a setting, to a certain extent, the modularization of the magnetic force output member 11, the magnetic force receiving member 12, the first driving member 2 and the second driving member 4 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.

[0117] At the same time, by arranging the second driving member 4 in the receiving groove 61, the second driving member 4 can be limited and protected to a certain extent, ensuring the stability of the second driving member 4, and further improving the stability of the process of magnetic coupling and decoupling between the driving magnetic force output member 11 and the magnetic force receiving member 12.

[0118] Exemplarily, for example, the driving mechanism 10 can also be connected to the door body 300 through the mounting housing 6.

[0119] In some embodiments, referring to Figure 2 , Figure 3 and Figure 8 and Figure 9 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 for the connector 20 to extend and move is formed on the front sealing door 200.

[0120] 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 of the device 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.

[0121] 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.

[0122] In some embodiments, referring to Figures 6 to 9 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.

[0123] With this setting, the installation and support of the driving mechanism 10 on the front sealing door 200 are realized through the backplane connection seat 7, and at the same time, the driving mechanism 10 is detachably connected to the front sealing door 200, with convenient assembly and high assembly efficiency. Moreover, when one of the driving structure 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.

[0124] In some embodiments, referring to Figures 4 to 6 as shown, the connector 20 includes a first connecting rod 202 and a second connecting rod 203. Among them, one end of the first connecting rod 202 is connected to the magnetic coupling structure 1, 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.

[0125] With this setting, it is convenient to drive the first connecting rod 202 and the second connecting rod 203 by the magnetic coupling structure 1 to drive the door body 300 to move, so as to realize the opening and closing of the door body 300 relative to the front sealing door 200, and the door body 300 is more flexible when opening and closing.

[0126] Moreover, such an arrangement facilitates the setting of the driving mechanism 10 on the side of the front sealing door 200 away from the door body 300, enabling a part of the first connecting rod 202 and the second connecting rod 203 to extend from the avoidance notch 2001 on the front sealing door 200 to the outside of the front sealing door 200, so as to drive the door body 300 to move more flexibly and realize the opening and closing of the door body 300.

[0127] Continue to refer to Figures 1 to 11 As shown, this embodiment also provides a laundry treatment device, including a door body 300, a front sealing door 200, and a door lock device 100.

[0128] By connecting the door lock device 100 between the door body 300 and the front sealing door 200, the closing or opening of the door body 300 relative to the front sealing door 200 is realized.

[0129] The structure and implementation principle of the door lock device 100 in this embodiment are the same as those of the door lock device 100 provided in the above embodiment, and can bring the same or similar technical effects. The description of the above embodiment can be referred to.

[0130] Other technical features are the same as those in the above embodiment, and can bring the same or similar technical effects, which will not be elaborated one by one here. Specifically, the description of the above embodiment can be referred to.

[0131] Continue to refer to Figures 1 to 11 As shown, this embodiment also provides a method for controlling the opening and closing of a laundry treatment device. This method can be executed by part or all of the laundry treatment device provided in the above embodiment. Specifically, the method includes:

[0132] S101: Drive the connecting member 20 through the magnetic coupling structure 1 to close the door body 300 relative to the front sealing door 200, or to open the door body 300 relative to the front sealing door 200.

[0133] Specifically, the connecting member 20 is driven through the magnetic coupling structure 1 to realize the opening and closing of the door body 300, which is convenient for users. To a certain extent, it avoids the situation of manually operating the door body 300 for opening and closing by users, saves manpower, and thus greatly improves the user experience.

[0134] The structure and implementation principle of the laundry treatment device in this embodiment are the same as those of the laundry treatment device provided in the above embodiment, and can bring the same or similar technical effects. The description of the above embodiment can be referred to.

[0135] Further, after the step of driving the connecting member 20 through the magnetic coupling structure 1, the method further includes:

[0136] S102: Detect the angular velocity of the connecting member 20.

[0137] By detecting the angular velocity of the connection member 20 , it is convenient to obtain the angular velocity of the connection member 20 , thereby obtaining the angular velocity of the door body 300 relative to the front sealing door 200 .

[0138] S103: When the angular velocity is zero, the second driving member 4 drives the magnetic force output member 11 and the magnetic force receiving member 12 to decouple.

[0139] 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 magnetic output member 11 to move in a direction away from the magnetic receiving member 12 to decouple the magnetic output member 11 and the magnetic receiving member 12. This blocks the power transmission between the magnetic output member 11 and the magnetic receiving member 12, and the user can still switch to manual operation to open and close the door body 300.

[0140] When the angular velocity is not zero, it indicates 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 .

[0141] Reference Figure 11 As shown, exemplary, a specific example is used to further illustrate the door opening and closing control method of a clothing processing device:

[0142] Taking the second driving member 4 as an electric push rod and the first driving member 2 including the driving motor 21 as an example, assuming that in the initial state the door body 300 is closed relative to the front sealing door 200, the electric push rod is in the original state without power and the magnetic receiving member 12 and the magnetic output member 11 are magnetically coupled.

[0143] Specifically, when the door body 300 needs to be opened, for example, the main controller of the laundry processing device can be used to disengage the lock hook 301 of the electromagnetic spring lock from the lock slot 2002, and the door body 300 can be rotated by a preset angle relative to the front sealing door 200, for example, the door body 300 is rotated to open 0°-4°. That is, when the door body 300 is opened, the electromagnetic spring lock is activated to open the door body by 0°-4°.

[0144] Then, by controlling the driving motor 21 to work, the magnetic output member 11 is driven by the driving motor 21 to rotate, and the magnetic output member 11 will rotate synchronously with the magnetic receiving member 12, and drive the connecting member 20 to rotate so that the door body 300 rotates in a direction away from the front sealing door 200, so that the door body 300 continues to rotate and open, for example, the door body 300 continues to rotate until the angle with the front sealing door 200 is 150° and then stops.

[0145] 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 indicates 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 inability of the front sealing door 200 to continue rotating. At this time, the electric push rod is energized to push out the magnetic force output member, that is, the magnetic force output member 11 is moved outward in a direction away from the magnetic force receiving member 12, so that the magnetic force output member and the magnetic force receiving member are decoupled, and the driving motor stops working. At this time, the automatic opening of the door body is stopped, and it is switched to manual door opening. When the angular velocity detected by the angular velocity sensor 5 is not zero, it indicates that there is no obstacle outside the door body. The electric push rod is in the original state, the magnetic force output member 11 and the magnetic force receiving member 12 are coupled, the door body automatically opens, and the door body rotates and opens to 150° and then stops.

[0146] 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 will also decouple the magnetic force output member 11 and the magnetic force receiving member 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.

[0147] Other technical features are the same as those in the above embodiments and can bring the same or similar technical effects, which will not be elaborated one by one here. For details, reference can be made to the description of the above embodiments.
