Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0044] The embodiment of the present application provides a door body component, a control method for the door body component, and a washing machine to solve the problem that when there is insufficient space or an obstacle on the outward turning side of the door body, it affects the user's putting in and taking out of clothes. The following will be described in conjunction with the accompanying drawings.

[0045] Please refer to Figures 1 to 4 , Figure 1 The first structural schematic diagram of the door body component provided by the embodiment of the present application; Figure 2 The second structural schematic diagram of the door body component provided by the embodiment of the present application; Figure 3 For Figure 1 The exploded structural schematic diagram of the door body component shown; Figure 4 A structural schematic diagram of the fixed bracket in the door body component provided by the embodiment of the present application.

[0046] An embodiment of the present application provides a door assembly 100 applicable to a washing machine. The door assembly 100 includes a door panel 11, a fixing bracket 13, a driving bracket 15, and a fan blade 17. An opening 111 is provided on the door panel 11. The fixing bracket 13 is installed on one side of the door panel 11. The driving bracket 15 is located on the side of the door panel 11 facing the fixing bracket 13, that is, the driving bracket 15 and the fixing bracket 13 are located on the same side of the door panel 11. The fan blade 17 can close the opening 111 on the door panel 11. The fan blade 17 includes a fan blade body 172, a first connecting portion 173, and a second connecting portion 174. Both the first connecting portion 173 and the second connecting portion 174 are provided on the fan blade body 172. The fan blade body 172 is rotatably installed on the fixing bracket 13 through the first connecting portion 173. The fan blade body 172 is also rotatably connected to the driving bracket 15 through the second connecting portion 174. The driving bracket 15 can rotate and drive the second connecting portion 174 to rotate around the first connecting portion 173, so that the fan blade body 172 rotates around the first connecting portion 173 and exposes the opening 111.

[0047] In this embodiment, one end of the fan blade body 172 is rotatably installed on the fixing bracket 13 through the first connecting portion 173, that is, the fan blade body 172 can rotate around the first connecting portion 173 and gradually expose the opening 111. When the fan blade body 172 rotates, it never turns outwards and is parallel to the opening 111, that is, it does not occupy the space outside the door panel 11, that is, the space on the side of the door panel 11 away from the fixing bracket 13. When the space outside the door is insufficient or there are obstacles, it does not affect the fan blade 17 to close or expose the opening 111, thus not affecting the user to put in or take out clothes.

[0048] It can be understood that the door assembly 100 in the embodiment of the present application can be applicable to clothing treatment devices such as washing machines, dryers, and washing and drying integrated machines. In this embodiment, a washing machine is taken as an example for description.

[0049] Specifically, please refer to Figure 3 and Figure 4 . In this embodiment, the first connecting portion 173 is a through-hole structure, that is, a through-hole structure is provided on the fan blade body 172, and a first protrusion 136 is provided on the fixing bracket 13. The first protrusion 136 passes through the first connecting portion 173 so that the fan blade body 172 is rotatably installed on the fixing bracket 13. The second connecting portion 174 is a protrusion structure. The second connecting portion 174 is provided on the side of the fan blade body 172 away from the door panel 11. A first through-hole 1521 is provided on the driving bracket 15. The second connecting portion 174 passes through the first through-hole 1521 so that the fan blade body 172 is rotatably connected to the driving bracket 15.

[0050] In this embodiment, there are five fan blades 17. When the fan blades 17 close the opening 111, partial edges of all the fan blades 17 are mutually attached to form a quasi-circular plate surface. When it is necessary to expose the opening 111, all the fan blades 17 rotate respectively with their first connection parts as the rotation centers and move away from each other, so that the fan blades 17 are separated from each other. It can be understood that the number of the fan blades 17 is not limited to this, and it can also be any other number.

[0051] Further, please refer to Figure 5 and Figure 6 , Figure 5 which is an exploded structural schematic diagram of the driving bracket 15 in the door body assembly 100 provided by the embodiment of the present application; Figure 6 which is a structural schematic diagram of the fixed bracket and the driving bracket in the door body assembly provided by the embodiment of the present application.

[0052] In this embodiment, the driving bracket 15 includes an opening and closing driven wheel 151 and a connecting rod 152. The opening and closing driven wheel 151 can rotate with the center line of the opening and closing driven wheel 151 as the axis, that is, the opening and closing driven wheel 151 can rotate around its own axis. A first through hole 1521 is arranged at one end of the connecting rod 152, so that the fan blade body 172 can be rotatably connected with the connecting rod 152, that is, one end of the connecting rod 152 is rotatably connected with the second connection part 174 of the fan blade body 172, and the other end of the connecting rod 152 is rotatably connected with the opening and closing driven wheel 151. When the opening and closing driven wheel 151 rotates, the opening and closing driven wheel 151 drives the connecting rod 152 to rotate, so that the connecting rod 152 drives the second connection part 174 to rotate around the first connection part 173, and further rotates the fan blade body 172 to expose the opening 111.

[0053] Specifically, a second convex part 1512 is arranged on the opening and closing driven wheel 151, and a second through hole 1522 is arranged at the end of the connecting rod 152 far from the first through hole 1521. The second convex part 1512 passes through the second through hole 1522, so that the connecting rod 152 is rotatably connected with the opening and closing driven wheel 151.

[0054] A limiting part (not marked in the figure) is arranged at the end of the second connection part 174 far from the fixed bracket 13 to prevent the fan blade body 172 from separating from the fixed bracket 13. The first convex part 136 and the second convex part 1512 are also provided with limiting parts to prevent the fan blade body 172 from separating from the driving bracket 15 and prevent the connecting rod 152 from separating from the opening and closing driven wheel 151.

[0055] Exemplarily, please refer to Figures 1 to 3, in this embodiment, the door panel 11 includes a panel body 112 and a limiting post 113. The limiting post 113 is fixedly connected to the side of the panel body 112 facing the fixed bracket 13. The fixed bracket 13 includes a bracket body 131 and a first connecting member 133. Among them, a first protrusion 136 is provided on the bracket body 131 so that the fan blade body 172 is rotatably mounted on the bracket body 131. One end of the first connecting member 133 is fixedly connected to the bracket body 131, and the other end of the first connecting member 133 is sleeved on the limiting post 113 so that the fixed bracket 13 is mounted on the panel body 112 of the door panel 11. And a limiting member 114 is provided at the end of the limiting post 113 away from the panel body 112. The limiting member 114 can limit the fixed bracket 13 from moving away from the panel body 112, that is, the first connecting member 133 is limited between the limiting member 114 and the panel body 112 to prevent the fixed bracket 13 from falling off the panel body 112.

[0056] In this embodiment, there are at least two first connecting members 133, and the number of the limiting posts 113 is the same as that of the first connecting members 133 and they correspond one by one, so that the first connecting member 133 sleeved on the limiting post 113 can limit the fixed bracket 13 from rotating relative to the door body.

[0057] Please combine Figures 1 to 3 , refer to Figure 7 and Figure 8 , Figure 7 is the first structural schematic diagram of the drive assembly in the door body assembly provided by the embodiment of the present application; Figure 8 is the second structural schematic diagram of the drive assembly in the door body assembly provided by the embodiment of the present application. In order to enable the opening and closing driven wheel 151 to rotate to drive the fan blade body 172 to rotate, in this embodiment, the door body assembly 100 further includes a drive assembly 19. The drive assembly 19 includes a drive motor 191, a rotating shaft 192 and an opening and closing driving wheel 195. Among them, the opening and closing driving wheel 195 is fixedly connected to the rotating shaft 192, and the opening and closing driving wheel 195 is also connected to the opening and closing driven wheel 151. The drive motor 191 is connected to the rotating shaft 192 and can drive the rotating shaft 192 to axially rotate, so that the opening and closing driving wheel 195 drives the opening and closing driven wheel 151 to rotate. And the door body assembly 100 can control the opening of the door through the drive assembly, without the user manually opening the door, which is convenient to operate.

[0058] Specifically, in this embodiment, the opening and closing driving wheel 195 and the opening and closing driven wheel 151 are meshed (not shown in the figure) and connected, that is, both the opening and closing driving wheel 195 and the opening and closing driven wheel 151 are gears and are meshed with each other, so that the opening and closing driven wheel 151 can rotate in the opposite direction relative to the opening and closing driving wheel 195. It can be understood that the opening and closing driving wheel 195 can also be rotationally connected to the opening and closing driven wheel 151 in other ways. For example, rubbers with a high coefficient of friction are provided on the sides of the opening and closing driving wheel 195 and the opening and closing driven wheel 151 in contact with each other.

[0059] Further, please refer to Figures 1 to 3 and refer to Figures 6 to 8 . In this embodiment, the drive motor 191 is fixedly connected to the fixed bracket 13. The drive assembly 19 further includes a lifting driving wheel 196. The lifting driving wheel 196 is fixedly connected to the rotating shaft 192 and is spaced apart from the opening and closing driving wheel 195. The door panel 11 further includes a lifting shaft 115. The lifting shaft 115 is fixed to the side of the plate body 112 facing the driving bracket 15. The lifting driving wheel 196 is screwed to the lifting shaft 115. When the drive motor 191 drives the rotating shaft 192 to drive the lifting driving wheel 196 to rotate, the lifting driving wheel 196 moves axially along the lifting shaft 115 through the thread in contact with the lifting shaft 115, that is, the entire drive assembly 19 can also move axially along the lifting shaft 115. And since the fixed bracket 13 is fixedly connected to the drive motor 191 and the fixed bracket 13 is slidably sleeved on the limit post 113, the drive motor 191 can drive the fixed bracket 13 to move axially along the lifting shaft 115, that is, the fixed bracket 13 can move axially along the limit post 113. The fan blade body 172 is rotatably fixed to the fixed bracket 13. Therefore, the fan blade 17 will move axially along the limit post 113 with the fixed bracket 13.

[0060] In this embodiment, spiral threads (not shown in the figure) are provided on the sides of the lifting driving wheel 196 and the lifting shaft 115 in contact with each other, so that when the lifting driving wheel 196 rotates relative to the lifting shaft 115, the threads cooperate with each other, so that the lifting driving wheel 196 can move axially along the lifting shaft 115 when rotating relative to the lifting shaft 115.

[0061] Based on this, when the fan blade 17 closes the opening 111 of the door panel 11, the drive motor 191 drives the lifting driving wheel 196 to rotate, so that the fan blade 17 moves toward the side close to the plate body 112 until the fan blade 17 is flush with the opening 111, which can make the fan blade 17 better close the opening 111, and there is no height difference between the fan blade 17 and the plate body 112, which can avoid the easy entrapment of sundries due to the height difference between the fan blade 17 and the plate body 112.

[0062] Please refer to Figures 1 to 3 and refer to Figure 4 , Figure 7 and Figure 8 . In this embodiment, the fixed bracket 13 further includes a second connecting member 135. The second connecting member 135 is fixedly connected to the bracket body 131, and the second connecting member 135 is also fixedly connected to the drive motor 191. Specifically, the second connecting member 135 is provided with a mounting hole 1351. The drive motor 191 passes through the mounting hole 1351 and is fixedly connected to the second connecting member 135, so that the drive assembly 19 is fixedly connected to the fixed bracket 13. Thus, when the drive motor 191 moves axially along the lifting shaft 115, the fixed bracket 13 can be driven to move through the second connecting member 135.

[0063] It can be understood that when the fan blade 17 is flush with the opening 111, if the fan blade 17 rotates at this time, the fan blade 17 will be interfered by the inner wall of the opening 111, resulting in inability to rotate and expose the opening 111. Based on this, in this embodiment, a first notch 1951 is provided on the lifting driving wheel 196, and a second notch 1952 is provided on the opening and closing driving wheel 195.

[0064] When the opening and closing driving wheel 195 is connected to the opening and closing driven wheel 151, the opening and closing driving wheel 195 can drive the opening and closing driven wheel 151 to rotate, so that the fan blade body 172 rotates to expose or close the opening 111. When the first notch 1951 rotates to the side close to the opening and closing driven wheel 151, the opening and closing driving wheel 195 is disengaged from the opening and closing driven wheel 151. After the disconnection, the opening and closing driving wheel 195 no longer drives the opening and closing driven wheel 151 to rotate;

[0065] When the lifting driving wheel 196 is screwed to the lifting shaft 115, the lifting driving wheel 196 can rotate relative to the lifting shaft 115 and move axially along the lifting shaft 115, so that the driving assembly 19 moves axially along the lifting shaft 115. When the second notch 1952 rotates to the side close to the lifting shaft 115, the lifting driving wheel 196 is disengaged from the screw connection with the lifting shaft 115. After the disconnection, the lifting driving wheel 196 no longer moves axially along the lifting shaft 115;

[0066] Moreover, when the opening and closing driving wheel 195 is connected to the opening and closing driven wheel 151, the lifting driving wheel 196 is disengaged from the screw connection with the lifting shaft 115; when the lifting driving wheel 196 is screwed to the lifting shaft 115, the opening and closing driving wheel 195 is disengaged from the opening and closing driven wheel 151, that is, when the fan blade 17 closes or exposes the opening 111, the lifting driving wheel 196 does not drive the driving motor 191 to perform the lifting action along the axial direction of the lifting shaft 115. When the lifting driving wheel 196 drives the driving motor 191 to perform the lifting action along the axial direction of the lifting shaft 115, the driving motor 191 does not drive the opening and closing driven wheel 151 to rotate, and then the fan blade 17 does not rotate either.

[0067] After the clothes are put in, the driving motor 191 drives the rotating shaft 192 to rotate, and the rotating shaft 192 drives the opening and closing driven wheel 151 and the lifting driving wheel 196 to rotate at the same time. The opening and closing driving wheel 195 is first connected to the opening and closing driven wheel 151, and rotates to drive the fan blades 17 to rotate and close the opening 111. At this time, the second notch 1952 on the lifting driving wheel 196 corresponds to the lifting shaft 115. After the fan blades 17 close the opening 111, the first notch 1951 of the opening and closing driving wheel 195 rotates to the side close to the opening and closing driven wheel 151, so that the fan blades 17 stop rotating. At the same time, the lifting shaft 115 is screwed to the lifting driving wheel 196, and the lifting driving wheel 196 rotates relative to the lifting shaft 115, so that the fan blades 17 move axially along the lifting shaft 115 and are flush with the opening 111, and the closing action is completed at this time. When it is necessary to expose the opening 111 to take out the clothes, it is only necessary to drive the rotating shaft 192 in the reverse direction to drive the opening and closing driven wheel 151 and the lifting active wheel 196 to rotate in the reverse direction, that is, first move the fan blade 17 axially in the reverse direction along the lifting shaft 115 to stagger it at a certain height from the opening 111, and then rotate the fan blade 17 to expose the opening 111, thereby avoiding the fan blade 17 being interfered by the inner wall of the opening 111 during rotation.

[0074] 302, obtaining a current of a driving motor;

[0075] 303. If the current is outside the preset current range, drive the drive motor to rotate in a second direction so that the fan blades rotate to expose the opening, and the second direction is opposite to the first direction.

[0076] Optionally, the control method further includes: if the current is within a preset current range, close the door normally.

[0077] It should be noted that after detecting that the current of the drive motor is outside the preset current range, the operation of the drive motor can be stopped first, and then rotated in the second direction, that is, the motor is stopped first and then reversed. The stop is used as a buffer for the motor reversal to avoid faults.

[0078] It can be understood that there are various situations that will cause the current of the drive motor to be outside the preset current range. In most cases, when the fan blade rotates to close the opening, the clothes are clamped, resulting in the fan blade being interfered by the clothes and unable to completely close the opening. The resistance of the drive motor increases, and then the current anomaly occurs. This embodiment is described by taking the fan blade being interfered by the clothes as an example. When the current of the drive motor is outside the preset current range, that is, after the current anomaly, the drive motor rotates in the reverse direction to expose the opening, so that the user can remove the obstacle, or rotate the fan blade to remove the clothes interference, and the door closing command can be executed again.

[0079] Further, to solve the problem that the fan blade rotation causes the clothes to be clamped, in this embodiment, the washing machine further includes an inner tub and clothes. When the clothes are clamped by the fan blade and the current of the drive motor is outside the preset current range, after driving the drive motor to rotate in the second direction, the control method of the door body assembly further includes:

[0080] Control the inner tub to rotate so that the clothes are separated from the fan blade and fall into the inner tub.

[0081] Optionally, after the inner tub rotates, the control method further includes: returning to 301 and starting the cycle again.

[0082] It can be understood that when the clothes are clamped by the fan blade, generally most of the clothes are already in the inner tub, and the structures such as the corners of the clothes are wound around the fan blade. Therefore, rotating the fan blade to expose the opening can scrape the part of the clothes hanging on the fan blade against the inner wall of the opening, so that the clothes fall into the inner tub; if the inner tub is controlled to rotate, the rotation of the inner tub can rub the part of the clothes that has entered the inner tub, and the rotation of the inner tub will generate vibrations, so that the clothes are rotated and rubbed by the inner tub or separated from the fan blade due to the vibration and fall into the inner tub, so that the washing machine can automatically eliminate the problem of the clothes being clamped without manual operation by the user. After the clothes fall into the inner tub, drive the drive motor to rotate in the first direction again to close the opening.

[0083] After obtaining the current of the drive motor, the control method of the door body assembly further includes:

[0084] If the current is outside the preset current range, the number of current anomaly times increases by one;

[0085] If the number of current anomalies is less than or equal to a preset number of anomalies, drive the drive motor to rotate in a second direction, so that the fan blade rotates to expose the opening, and the second direction is opposite to the first direction;

[0086] Control the inner tub to rotate, return to 301 and start the cycle again;

[0087] If the number of current anomalies is greater than the preset number of anomalies, stop the operation of the drive motor.

[0088] It can be understood that when the inner tub rotates multiple times and the clothes clamped or wound on the fan blade still cannot fall into the inner tub, continuously rotating the fan blade and the inner tub to adjust the clothes will be inefficient and waste the energy consumption of the washing machine. Therefore, after the inner tub rotates a certain number of times and the current anomaly is still detected after each rotation, that is, the clothes cannot be adjusted to the inner tub after rotation, the drive motor stops running and waits for the user to manually adjust to avoid situations such as the clothes getting stuck between the fan blade and the inner tub due to multiple rotations.

[0089] In addition, an alarm can also be set in the washing machine. After the drive motor stops running, the alarm prompts the user that the door body fails to close properly, so that the user can manually adjust the clothes in time.

[0090] The door body assembly provided by the embodiment of the present application includes a door panel, a fixed bracket and a fan blade. There is an opening on the door panel. The fixed bracket and the drive bracket are both located on the same side of the door panel. The fan blade is located between the door panel and the fixed bracket. The fan blade can close the opening. The fan blade includes a fan blade body, a first connecting portion and a second connecting portion. The first connecting portion and the second connecting portion are both arranged on the fan blade body. The fan blade is rotatably installed on the fixed bracket through the first connecting portion. The fan blade body is rotatably connected to the drive bracket through the second connecting portion. The drive bracket can drive the second connecting portion to rotate, so that the fan blade body rotates around the first connecting portion and exposes the opening. When the fan blade rotates, the fan blade does not turn outwards and is always parallel to the opening, so as not to occupy the space on the side of the door panel away from the fixed bracket. When there is insufficient space or an obstacle on the side where the door body turns outwards, it does not affect the user to put in and take out clothes. The present application also provides a control method for the door body assembly applicable to the above door body assembly and a washing machine including the above door body assembly.
