[0066] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0067] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0068] The present application embodiment provides a clothes processing device for implementing the inner door locking feedback method of the present application embodiment. Figures 1 to 7 , comprising a housing, a drum 1, an inner door assembly 2, and an automatic opening unit. The housing has an opening. The drum 1 has a clothing delivery port 1a connected to the opening. The drum 1 is disposed in the housing. The inner door assembly 2 is mounted on the drum 1 and can rotate with the drum 1. The state of the inner door assembly 2 includes a closed state in which the clothing delivery port 1a is closed and an open state in which the clothing delivery port 1a is opened. The state of the outer door assembly 5 includes a closed state in which the opening is closed and an open state in which the opening is opened. The automatic opening unit always applies a force to the inner door assembly 2 within an angle α to resist the closed state of the inner door assembly 2. When the inner door assembly 2 is in a closed state, the force applied by the automatic opening unit to the inner door assembly 2 is less than the locking force of the inner door assembly 2. When the inner door assembly 2 is in an open state, the force applied by the automatic opening unit to the inner door assembly 2 causes the inner door assembly 2 to open to drive the outer door assembly 5 from a closed state to an open state. Wherein, a plane perpendicular to the central axis of the drum 1 is defined as a first plane, and the angle α is an angle between the inner door 21 of the inner door assembly 2 and the first plane.

[0069] The clothing processing device of the embodiment of the present application can be a washing machine or a washer-dryer. By way of example, the clothing processing device is a drum 1 washing machine, and the axis of the drum 1 of the clothing processing device extends approximately in a horizontal direction, that is, the axis of the drum 1 can be set horizontally or have a certain inclination angle.

[0070] See also Figures 1 to 7 The front end of the drum 1 is provided with a clothing loading opening 1a.

[0071] Exemplarily, the drum 1 includes a body 11 and a front cover 13 disposed at the front end of the body 11. The front cover 13 is formed with a laundry inlet 1a, and defines a laundry treatment chamber 1b with the body 11.

[0072] Exemplarily, the drum 1 further comprises a rear cover, which is arranged at the rear end of the cylinder body 11 .

[0073] Exemplarily, the drum 1 is a non-porous drum. That is, the drum 1 can hold water, and when the laundry processing device is in the process of washing clothes, the washing water is held in the drum 1, which can avoid the problem of dirt and grime easily accumulating between the inner and outer barrels caused by holding water in the outer barrel in the prior art.

[0074] For example, see Figures 1 to 6 The clothing processing device further comprises a housing 6, the drum 1 is arranged in the housing 6, and the housing 6 has an opening communicating with the clothing loading port 1a.

[0075] It should be noted that, in the embodiment of the present application, the clothing processing device may be configured with an outer barrel or may not be configured with an outer barrel.

[0076] In the embodiment equipped with an outer tub, the drum 1 can drain water centrally through the outer tub, that is, during the drainage process, the water in the drum 1 first enters the outer tub and then is discharged through the drainage system of the outer tub. However, during the washing process of the drum 1, the washing water will not enter the outer tub.

[0077] In the embodiment without an outer tub, the drum 1 can be drained directly through the drainage system.

[0078] The inner door assembly 2 is installed on the drum 1 and can rotate with the drum 1. Therefore, the seal between the inner door assembly 2 and the drum 1 is a static seal with high sealing reliability and is not easy to wear, thereby improving the service life of the inner door assembly 2.

[0079] The state of the inner door assembly 2 includes a closed state for closing the clothing inlet 1a and an open state for opening the clothing inlet 1a. That is, the inner door assembly 2 can be switched between a closed position for closing the clothing inlet 1a and an open position for opening the clothing inlet 1a, that is, the inner door assembly 2 is used to open or close the clothing inlet 1a.

[0080] See also Figures 1 to 6 , the clothing processing device also includes an outer door assembly 5.

[0081] The states of the outer door assembly 5 include a closed state for closing the opening and an open state for opening the opening, that is, the outer door assembly 5 is used to open or close the opening.

[0082] The inner door assembly 2 is arranged on the inner side of the outer door assembly 5 and is used to open or close the clothing loading opening 1 a , that is, the clothing loading opening 1 a is sealed by the inner door assembly 2 .

[0083] It should be noted that when the user needs to take out the clothes in the inner drum, the inner door assembly 2 can open the clothes loading port 1a.

[0084] Exemplarily, the inner door assembly 2 closes the clothing inlet 1a and can be locked on the drum 1 so that the inner door assembly 2 can rotate along with the drum 1. This can prevent the detergent in the drum 1 from leaking and can prevent the clothing from being thrown out, hitting the shell, causing safety accidents, etc. due to the opening of the inner door assembly 2 during the operation of the clothing processing device.

[0085] The automatic opening unit always applies a force to the inner door assembly 2 within the range of angle α to resist the closed state of the inner door assembly 2. When the inner door assembly 2 is in the closed state, the force applied by the automatic opening unit to the inner door assembly 2 is less than the locking force of the inner door assembly 2. When the inner door assembly 2 is in the open state, the force applied by the automatic opening unit to the inner door assembly 2 causes the inner door assembly 2 to open to drive the outer door assembly 5 from the closed state to the open state. Among them, the plane perpendicular to the central axis of the drum 1 is defined as the first plane, and the angle α is the angle between the inner door 21 of the inner door assembly 2 and the first plane.

[0086] That is to say, if the inner door assembly 2 is locked on the drum 1 in the closed position, the inner door assembly 2 will not open the clothing loading port 1a. If the inner door assembly 2 is not locked on the drum 1 in the closed position, the force exerted by the automatic opening unit on the inner door assembly 2 will drive the inner door assembly 2 to open the clothing loading port 1a, so that the inner door assembly 2 is opened to a certain angle, that is, at this time, the inner door assembly 2 can open the clothing loading port 1a, avoiding the inner door assembly 2 from being half-closed at the clothing loading port 1a, which is conducive to the user to find out in time that the inner door assembly 2 is not closed properly, and to close the inner door assembly 2 again.

[0087] The clothing processing device provided in the embodiment of the present application includes a housing, a drum 1, an inner door assembly 2, an outer door assembly 5 and an automatic opening unit. When it is necessary to wash clothes in the drum 1, the inner door assembly 2 closes the clothing delivery port 1a, and the washing water is enclosed in the drum 1 by the inner door assembly 2. By setting the automatic opening unit, the automatic opening unit always applies a force to the inner door assembly 2 within the angle α range to resist the closed state of the inner door assembly 2. Therefore, if the inner door assembly 2 is not closed in place, that is, the inner door assembly 2 is not locked on the drum 1, at this time, the inner door assembly 2 will open the clothing delivery port 1a under the force of the automatic opening unit, so that the inner door assembly 2 can be prevented from being half-closed on the drum 1, which is conducive to the user to promptly discover that the inner door assembly 2 is not closed in place and reclose the inner door assembly 2, thereby improving the problem of liquid leakage, as well as the problems of clothes being thrown out, hitting the shell, and safety accidents caused by the opening of the inner door assembly 2, thereby improving the safety performance.

[0088] The automatic opening unit always applies a force to the inner door assembly 2 within the range of angle α to resist the closed state of the inner door assembly 2. Exemplarily, a plane perpendicular to the central axis of the drum 1 is defined as a first plane. In the closed position, the inner door assembly 2 is parallel to the first plane, and within the range of angle α, it means that the angle between the inner door assembly 2 and the first plane is less than or equal to α.

[0089] See also Figure 2 , the center axis of the drum 1 is represented by Z.

[0090] In the closed position of the inner door assembly 2, the inner door assembly 2 is parallel or substantially parallel to the first plane. When the inner door assembly 2 is parallel to the first plane, the angle between the inner door assembly 2 and the first plane is 0°.

[0091] Exemplarily, the angle α ranges from 0° to 60°, such as 0°, 1°, 2°, 3°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55° or 60°, etc.

[0092] Of course, when the angle α is in the range of 0°-60°, when the angle between the inner door assembly 2 and the first plane is less than or equal to 60°, if the inner door assembly 2 is not locked on the drum 1, the inner door assembly 2 will open the clothing inlet 1a under the action of the automatic opening unit, and the inner door assembly 2 can be opened to drive the outer door assembly 5 from a closed state to an open state, thereby facilitating the user to promptly discover that the inner door assembly is not closed in place and to close the inner door assembly 2 again.

[0093] It should be noted that there are many structural forms of the automatic opening unit, which are not limited here.

[0094] In some embodiments, see Figures 2 to 7 The automatic opening unit includes an elastic member 3. Within the range of angle α, the inner door assembly 2 and the drum 1 squeeze the elastic member 3 to cause the elastic member 3 to undergo elastic deformation. The elastic member 3 always applies a force to the inner door assembly 2 to resist the closed state of the inner door assembly 2. When the inner door assembly 2 is in the closed state, the force applied by the elastic member 3 to the inner door assembly 2 is less than the locking force of the inner door assembly 2. When the inner door assembly 2 is in the open state, the force applied by the automatic opening unit to the inner door assembly 2 causes the inner door assembly 2 to open and drive the outer door assembly 5 from the closed state to the open state.

[0095] The number of the elastic members 3 is not limited here, for example, it can be one or more.

[0096] The multiple mentioned in the embodiments of the present application refers to a number of two, or more than two.

[0097] The elastic member 3 is connected to the drum 1 and / or the inner door assembly 2, which means that the elastic member 3 can be connected to the drum 1, can also be connected to the inner door assembly 2, or can also be connected to the drum 1 and the inner door assembly 2.

[0098] For example, when there are multiple elastic members 3 , some of the elastic members 3 may be connected to the drum 1 , and another part of the elastic members 3 may be connected to the inner door assembly 2 .

[0099] The specific type of the elastic member 3 is not limited here, and it can be, for example, a spring or an elastic column 31 .

[0100] By setting the length of the elastic member 3, when the angle between the inner door assembly 2 and the first plane is less than a preset angle, the inner door assembly 2 and the drum 1 squeeze the elastic member 3 to cause the elastic member 3 to undergo elastic deformation. If the inner door assembly 2 is locked on the drum 1, the elastic member 3 remains in a deformed state to resist the closing state of the inner door assembly 2. If the inner door assembly 2 is not locked on the drum 1, the elastic member 3 restores the elastic deformation, and the force exerted by the elastic member 3 on the inner door assembly 2 causes the inner door assembly 2 to open and drive the outer door assembly 2 to be in an open state.

[0101] In some embodiments, see Figure 7 One side of the inner door assembly 2 has a rotation center, and the elastic member 3 is arranged on a side of the inner door assembly 2 away from the rotation center.

[0102] See also Figure 7 , the rotation center of the inner door assembly is represented by D.

[0103] One side of the inner door assembly 2 has a rotation center, and the inner door assembly 2 is rotatably disposed on the drum 1 through the rotation center to achieve closing and opening of the clothing loading port 1a.

[0104] The elastic member 3 is arranged on a side of the inner door assembly 2 away from the rotation center. The elastic member 3 applies a force to the inner door assembly 2 along the opening direction of the inner door assembly 2, which can form a large torque to open the inner door assembly 2 to a certain angle.

[0105] In some embodiments, see Figure 7 and Figure 8 The clothes processing device further comprises a connecting member 4 having a rotating shaft 41, and the inner door assembly 2 is rotatably connected to the drum 1 through the connecting member 4. The elastic member 3 comprises a torsion spring 32 arranged on the rotating shaft 41. When the angle between the inner door assembly 2 and the first plane is within the range of angle α, the torsion spring 32 applies a force to the inner door assembly 2 in the opening direction of the inner door assembly 2; when the angle between the inner door assembly 2 and the first plane is greater than the range of angle α, the torsion spring 32 applies a force to the inner door assembly 2 in the closing direction of the inner door assembly 2.

[0106] It can be understood that the torsion spring 32 includes a free state, a compressed working state, and a stretched working state. Specifically, the torsion spring 32 includes a first leg and a second leg. The free state refers to the state of the torsion spring 32 when it is not subjected to external force; the compressed working state refers to the torsion spring 32 being subjected to external compression force, so that the distance between the first leg and the second leg is smaller than the distance in the free state; the stretched working state refers to the torsion spring 32 being subjected to external tension, so that the distance between the first leg and the second leg is larger than the distance in the free state.

[0107] Therefore, the torsion spring 32 can be in a compressed working state to form a force on the inner door assembly 2 along the opening direction of the inner door assembly 2 (or a force on the inner door assembly 2 along the closing direction of the inner door assembly 2), or it can be in a stretched working state to form a force on the inner door assembly 2 along the opening direction of the inner door assembly 2 (or a force on the inner door assembly 2 along the closing direction of the inner door assembly 2), and there is no limitation here.

[0108] It can be understood that when the inner door assembly 2 switches between the closing direction and the opening direction, the direction of the force applied by the torsion spring 32 to the inner door assembly 2 is opposite, that is, there is a critical point in the opening angle. At this critical point, the torque applied by the torsion spring 32 to the inner door assembly 2 is, and the torsion spring 32 is in a free state.

[0109] Exemplarily, in some embodiments, the first leg of the torsion spring 32 presses on the drum 1 (or the door hinge 42), and the second leg presses on the inner door assembly 2 (or the reinforcement plate of the inner door 21). When the angle between the inner door assembly 2 and the first plane is less than a preset angle, the torsion spring 32 is in a compressed working state, and applies a force to the inner door assembly 2 along the opening direction of the inner door assembly 2 (to resist the closing state of the inner door assembly 2). When the angle between the inner door assembly 2 and the first plane is greater than the preset angle, the torsion spring 32 is in a stretched working state, and applies a force to the inner door assembly 2 along the closing direction of the inner door assembly 2 (to resist the opening state of the inner door assembly 2).

[0110] In other embodiments, the first leg of the torsion spring 32 presses on the box body 6, and the second leg presses on the inner door assembly 2 (or the reinforcement plate of the inner door 21). When the angle between the inner door assembly 2 and the first plane is less than the preset angle, the torsion spring 32 is in a stretched working state and applies a force to the inner door assembly 2 along the opening direction of the inner door assembly 2. When the angle between the inner door assembly 2 and the first plane is greater than the preset angle, the torsion spring 32 is in a squeezed working state and applies a force to the inner door assembly 2 along the closing direction of the inner door assembly 2.

[0111] In some embodiments, the elastic member 3 also includes an elastic column 31, one end of the elastic column 31 is connected to the inner door assembly 2, and the other end extends in a direction away from the inner door assembly 2. When the angle between the inner door assembly 2 and the first plane is within the angle α, the inner door assembly 2 and the roller 1 squeeze the elastic column 31 to cause the elastic column 31 to undergo elastic deformation. The elastic column 31 restores the elastic deformation and applies a force to the inner door assembly 2 to resist the closed state of the inner door assembly 2.

[0112] See also Figure 7 and Figure 8 In this embodiment, the elastic member 3 includes a torsion spring 32 and an elastic column 31. That is to say, by simultaneously arranging the torsion spring 32 and the elastic column 31, when the angle between the inner door assembly 2 and the first plane is within the angle α, the torsion spring 32 and the elastic column 31 simultaneously apply a force to the inner door assembly 2 to jointly resist the closing state of the inner door assembly 2, which is more conducive to avoiding the situation where the inner door assembly 2 is half-closed on the drum 1.

[0113] In some embodiments, the automatic opening unit includes a first magnetic member and a second magnetic member, the first magnetic member is disposed on the inner door assembly 2, and the second magnetic member is disposed on the drum 1. Within the range of angle α, the first magnetic member and the second magnetic member repel each other to resist the closed state of the inner door assembly 2. When the inner door assembly 2 is in the closed state, the repulsive force between the first magnetic member and the second magnetic member is less than the locking force of the inner door assembly 2. When the inner door assembly 2 is in the open state, the repulsive force between the first magnetic member and the second magnetic member causes the inner door assembly 2 to open to drive the outer door assembly 5 from the closed state to the open state.

[0114] The automatic opening unit is provided with a first magnetic member and a second magnetic member, and when the angle between the inner door assembly 2 and the first plane is within the range of angle α, the first magnetic member and the second magnetic member repel each other to resist the closed state of the inner door assembly 2. If the inner door assembly 2 is locked on the drum 1, the repulsive force between the first magnetic member and the second magnetic member is less than the locking force of the inner door assembly 2 locked on the drum 1, that is, the repulsive force between the first magnetic member and the second magnetic member cannot switch the inner door assembly 2 from the closed state to the open state, and if the inner door assembly 2 is not locked on the drum 1 (for example, it is half-closed on the drum 1), the repulsive force between the first magnetic member and the second magnetic member pushes the inner door assembly 2 to open until driving the outer door assembly 5 from the closed state to the open state.

[0115] In some embodiments, see Figures 1 to 7 The clothing treatment device further comprises a housing 6 and an outer door assembly 5. The housing 6 has an opening communicating with the clothing delivery port 1a. The outer door assembly 5 is used to open or close the opening. When the inner door assembly 2 is in a closed state and the outer door assembly 5 is in a closed state, there is an installation gap between the outer door assembly 5 and the inner door assembly 2.

[0116] That is to say, when the inner door assembly 2 and the outer door assembly 5 are both in a closed state, there is an installation gap between the outer door assembly 5 and the inner door assembly 2. The setting of the installation gap is used to avoid interference between the inner door assembly 2 and the outer door assembly 5, which may cause the outer door assembly 5 to not be closed properly, thereby improving the assembly reliability of the outer door assembly 5.

[0117] In some embodiments, see Figure 3 and Figure 5 The inner door assembly 2 includes an inner door 21 and a first locking portion 22, and the drum 1 includes a drum body 11 and a second locking portion 12. When the inner door 21 is in a closed position to close the clothing loading port 1a, the first locking portion 22 and the second locking portion 12 cooperate to lock the inner door 21 on the drum body 11. In other words, the inner door 21 and the drum body 11 cooperate through the first locking portion 22 and the second locking portion 12 to lock the inner door 21 on the drum body 11.

[0118] Specifically, one of the first locking portion 22 and the second locking portion 12 is a locking member, and the other is a lock core, which can be switched between a locking position and an unlocking position.

[0119] When the lock core is in the locked position, the locking member and the lock core are locked, and the inner door 21 and the drum 1 are relatively fixed, so the inner door 21 cannot be opened. When the lock core is in the unlocked position, the locking member and the lock core are unlocked, that is, the locking member and the lock core can move relative to each other, and the inner door 21 and the drum 1 are unlocked, and the inner door 21 can be opened and closed freely to realize the taking and putting of clothes.

[0120] In some embodiments, see Figure 3 and Figure 5 The clothing processing device may further include a door lock assembly 7 , and the outer door assembly 5 is locked on the box body 6 through the door lock assembly 7 .

[0121] It should be noted that the specific type of the door lock assembly 7 between the outer door assembly 5 and the box body 6 is not limited, as long as the outer door assembly 5 can be locked to the box body 6, or the outer door assembly 5 can be unlocked. For example, the door lock assembly 7 here can adopt any public electronic lock or any public mechanical lock.

[0122] In the related art, if the inner door assembly is not fully closed and the outer door assembly is arranged on the outside of the outer door assembly, it is difficult to find that the inner door assembly is not fully closed after the outer door assembly is closed.

[0123] In the embodiment of the present application, the force applied by the automatic opening unit to the inner door assembly 2 causes the inner door assembly 2 to open and drive the outer door assembly 5 from the closed state to the open state. In this way, the locking state of the inner door 21 can be indirectly understood by detecting the state of the outer door assembly 5 in place.

[0124] That is to say, if the inner door assembly 2 is not closed properly, that is, the inner door assembly 2 is not locked on the drum 1, at this time, the automatic opening unit applies a force to the inner door assembly 2, and the inner door assembly 2 will move in the opening direction under the force, and drive the outer door assembly 5 to move, so that the outer door assembly 5 switches from the position of closing the opening to the position of opening the opening, that is, the outer door assembly 5 is opened to a certain angle, which is further helpful for the user to promptly discover that the inner door assembly 2 and the outer door assembly 5 are not closed properly, and reclose the inner door assembly 2 and the outer door assembly 5, thereby improving the problem of liquid leakage, as well as the problems of clothes being thrown out, hitting the shell, and causing safety accidents due to the opening of the inner door assembly 2, thereby improving the safety performance.

[0125] Specifically, see Figure 3 and Figure 5 A first abutting portion 2a is provided on the inner door assembly 2, and a second abutting portion 5a is provided on the outer door assembly 5. When the inner door assembly 2 moves in the opening direction under the action of the elastic member 3, the first abutting portion 2a abuts against the second abutting portion 5a, and drives the outer door assembly 5 to open to a certain angle.

[0126] In some embodiments, the clothing processing apparatus further comprises an in-place detection device (not shown), which is used to detect the position of the outer door assembly 5 and output in-place information when the outer door assembly 5 is in a closed state.

[0127] In this way, the locking state of the inner door 21 can be indirectly understood by detecting the state of the outer door assembly 5 through the in-place detection device. When the inner door assembly 2 is locked on the drum 1, the washing program starts. If the state is abnormal, the user is reminded to check and adjust the closing state of the inner door assembly 2 and the outer door assembly 5 to ensure safe and reliable operation.

[0128] Specifically, the in-place detection device mainly detects the position of the outer door assembly 5 by means of signal transmission, and the signal transmitted by the in-place detection device may be an induction signal, a trigger signal, etc. Depending on the setting position and / or detection method of the in-place detection device, the in-place detection device may transmit a corresponding signal when the outer door assembly 5 is in a position to close the opening, and stop transmitting the signal when the outer door assembly 5 is not in a position to close the opening, which is equivalent to the in-place detection device transmitting the corresponding signal, outputting in-place information, and outputting non-in-place information when the in-place detection device stops transmitting the signal. Alternatively, the outer door assembly 5 may transmit the corresponding signal when it is not in a position to close the opening, and stop transmitting the signal when the outer door assembly 5 is in a position to close the opening, which is equivalent to the in-place detection device transmitting the corresponding signal, outputting non-in-place information, and outputting in-place information when the in-place detection device stops transmitting the signal.

[0129] In addition, there are different detection methods depending on the type of in-place detection device selected. For example, some in-place detection devices only need one detection element to detect whether the outer door assembly 5 is in a position to close the opening, while some in-place detection devices require a detection element to cooperate with other detection elements or trigger mechanisms to detect whether the outer door assembly 5 is in a position to close the opening. Which in-place detection devices can be used and how to perform the detection will be described in detail later.

[0130] Exemplarily, the in-position detection device may be an ultrasonic detection device, a pressure detection device, a micro switch, an infrared detection device, or a magnetic induction detection device, etc. When the outer door assembly 5 is in the position of closing the opening, the outer door assembly 5 is close to the ultrasonic sensor, and the ultrasonic sensor outputs in-position information, or, when the outer door assembly 5 is in the position of closing the opening, the outer door assembly 5 contacts the pressure sensor, and the pressure sensor outputs in-position information, or, when the outer door assembly 5 is in the position of closing the opening, the micro switch is triggered, and the micro switch outputs in-position information.

[0131] In a specific embodiment, please refer to Figures 1 to 6 After the user puts the clothes into the drum 1, the inner door assembly 2 and the outer door assembly 5 are closed in turn to start the program; if the inner door assembly 2 is closed and locked successfully, there is a certain installation gap between the inner door assembly 2 and the outer door assembly 5, and the in-place detection device senses that the outer door assembly 5 is in the closed opening position, the door lock assembly 7 locks the outer door assembly 5 to the box body 6, the program starts, and the washing begins; if the inner door assembly 2 fails to be closed and locked, the inner door assembly 2 automatically opens an angle, the inner door assembly 2 supports the outer door assembly 5 and rotates to open, the in-place detection device senses that the outer door assembly 5 is not in place, the door lock assembly 7 fails to lock, the washing program is paused and an alarm is sounded, prompting the user that the inner door assembly 2 is not closed and locked in place, and the operation needs to be repeated.

[0132] The present application also provides a method for feedback locking of the inner door of a clothes processing device. Fig. 9 , the inner door locking feedback method includes the following steps.

[0133] S100: Controlling the inner door assembly to close the clothing loading port, wherein the state of the inner door assembly includes a closed state in which the clothing loading port is closed and an open state in which the clothing loading port is opened.

[0134] Before washing or drying clothes, clothes are put into the drum 1 through the clothes inlet 1a, and then the clothes inlet 1a is closed by the inner door assembly 2. However, sometimes the inner door assembly 2 is not closed successfully, for example, it is half-closed on the drum 1, and thus, the state of the inner door assembly 2 includes a closed state in which the clothes inlet 1a is closed and an open state in which the clothes inlet 1a is opened.

[0135] S200: Controlling the outer door assembly to close the opening, wherein the state of the outer door assembly includes a closed state of closing the opening and an open state of opening the opening.

[0136] After the action of closing the inner door assembly 2, the outer door assembly 5 is controlled to close the opening.

[0137] S300: Before running the washing program, the state of the outer door assembly is obtained, and the state of the inner door assembly is determined based on the state of the outer door assembly.

[0138] In the related art, there is a situation where the inner door assembly fails to close successfully (for example, it is ajar on the drum), while the outer door assembly is able to close the opening. In this case, the problem that the inner door assembly fails to close successfully cannot be discovered. If the clothing processing equipment is started, it may cause leakage of detergent in the drum and safety problems, etc.

[0139] The inner door locking feedback method of the clothing processing device provided in the embodiment of the present application, the clothing processing device includes a box 6, a drum 1, an inner door assembly 2 and an outer door assembly 5. When it is necessary to wash clothes in the drum 1, the inner door assembly 2 closes the clothing delivery port 1a of the drum 1, the washing water is closed in the drum 1 by the inner door assembly 2, and the outer door assembly 5 closes the opening of the box 6. The state of the inner door assembly 2 includes a closed state of closing the clothing delivery port 1a and an open state of opening the clothing delivery port 1a. The state of the outer door assembly 5 includes a closed state of closing the opening and an open state of opening the opening. Before running the washing program, the state of the outer door assembly 5 is obtained, and the state of the inner door assembly 2 is determined based on the state of the outer door assembly 5. That is, the state of the inner door assembly 2 can be determined by obtaining the state of the outer door assembly 5. In this way, the inner door assembly 2 can be prevented from being half-closed on the drum 1, which is conducive to the user to promptly find that the inner door assembly 2 is not closed in place, and re-close the inner door assembly 2, thereby improving the problem of liquid leakage, and the problems of clothes being thrown out, hitting the shell, and safety accidents caused by the opening of the inner door assembly 2, thereby improving the safety performance.

[0140] In addition, since the outer door assembly 5 does not need to move during the operation of the clothing processing equipment, it is more conducive to the setting of the in-place detection device for obtaining the status of the outer door assembly 5, and it can simultaneously determine whether the inner door assembly 2 and the outer door assembly 5 are closed successfully, further improving the safety performance.

[0141] In some embodiments, Fig. 9 The “determining the state of the inner door component based on the state of the outer door component” in the illustrated embodiment can be implemented as the following steps:

[0142] S310: If the outer door assembly is in a closed state, it is determined that the inner door assembly is also in a closed state, and the washing program is started;

[0143] S320: If the outer door assembly is in the open state, it is determined that the inner door assembly is also in the open state, and the washing program is not started.

[0144] If the outer door assembly 5 is in a closed state, it is determined that the inner door assembly 2 is also in a closed state, that is, the inner door assembly 2 successfully closes the clothing delivery opening 1a. At this time, the outer door assembly 5 successfully closes the opening, that is, at this time, the inner door assembly 2 and the outer door assembly 5 of the clothing processing device are both successfully closed. If the outer door assembly 5 is in an open state, it is determined that the inner door assembly 2 is in an open state, that is, the inner door assembly 2 fails to close the clothing delivery opening 1a. In other words, as long as the inner door assembly 2 fails to close the clothing delivery opening 1a, the inner door assembly 2 will drive the outer door assembly 5 to open the opening. In this way, it is beneficial to determine the state of the inner door assembly 2 according to the state of the outer door assembly 5, thereby improving the safety performance of the clothing processing device.

[0145] In some embodiments, the laundry processing apparatus further comprises an automatic opening unit, which always applies a force to the inner door assembly 2 within the angle α to resist the closed state of the inner door assembly 2 .

[0146] Exemplarily, if the outer door assembly 5 is in an open state, it is determined that the inner door assembly 2 is also in an open state, including: when the inner door assembly 2 is in an open state, the force applied by the automatic opening unit to the inner door assembly 2 causes the inner door assembly 2 to open and drive the outer door assembly 5 from a closed state to an open state. If the outer door assembly 5 is in a closed state, it is determined that the inner door assembly 2 is also in a closed state, including: when the inner door assembly 2 is in a closed state, the force applied by the automatic opening unit to the inner door assembly 2 is less than the locking force of the inner door assembly 2.

[0147] That is to say, by setting the automatic opening unit, the automatic opening unit always applies a force to the inner door assembly 2 within the range of angle α to resist the closed state of the inner door assembly 2. If the inner door assembly 2 is not closed in place, that is, the inner door assembly 2 is not locked on the drum 1, at this time, the inner door assembly 2 will be opened under the force of the automatic opening unit to drive the outer door assembly 5 from the closed state to the open state. In this way, it can avoid the inner door assembly 2 being half-closed on the drum 1, which is conducive to the user to promptly discover that the inner door assembly 2 is not closed in place, and reclose the inner door assembly 2 and the outer door assembly 5, thereby improving the problem of liquid leakage, and the problems of clothes being thrown out, hitting the shell, and causing safety accidents due to the opening of the inner door assembly 2, thereby improving the safety performance. When the inner door assembly 2 is in the closed state, the force applied by the automatic opening unit to the inner door assembly 2 is less than the locking force of the inner door assembly 2.

[0148] In some embodiments, the automatic opening unit includes an elastic member 3. Within the range of angle α, the inner door assembly 2 and the drum 1 squeeze the elastic member 3 so that the elastic member 3 undergoes elastic deformation, and the elastic member 3 always applies a force to the inner door assembly 2 to resist the closed state of the inner door assembly 2. When the inner door assembly 2 is in the closed state, the force applied by the elastic member 3 to the inner door assembly 2 is less than the locking force of the inner door assembly 2. When the inner door assembly 2 is in the open state, the force applied by the elastic member 3 to the inner door assembly 2 causes the inner door assembly 2 to open to drive the outer door assembly 5 from the closed state to the open state.

[0149] See also Figure 2 , the center axis of the drum 1 is represented by Z.

[0150] In the closed position of the inner door assembly 2, the inner door assembly 2 is parallel or substantially parallel to the first plane. When the inner door assembly 2 is parallel to the first plane, the angle between the inner door assembly 2 and the first plane is 0°.

[0151] Exemplarily, the angle α ranges from 0° to 60°, such as 0°, 1°, 2°, 3°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55° or 60°, etc.

[0152] Of course, when the angle α is in the range of 0°-60°, when the angle between the inner door assembly 2 and the first plane is less than or equal to 60°, if the inner door assembly 2 is not locked on the drum 1, the inner door assembly 2 will open the clothing inlet 1a under the action of the automatic opening unit, and the inner door assembly 2 can be opened to drive the outer door assembly 5 from a closed state to an open state, thereby facilitating the user to promptly discover that the inner door assembly 2 is not closed in place and to close the inner door assembly 2 again.

[0153] It should be noted that the elastic member 3 has various structural forms, which are not limited here.

[0154] In some embodiments, see Figures 2 to 7 The elastic member 3 is connected to the drum 1 and / or the inner door assembly 2. When the angle between the inner door assembly 2 and the first plane is less than the preset angle, the inner door assembly 2 and the drum 1 squeeze the elastic member 3 to cause the elastic member 3 to undergo elastic deformation, and the elastic member 3 applies a force to the inner door assembly 2 along the opening direction of the inner door assembly 2 by restoring the elastic deformation.

[0155] The number of the elastic members 3 is not limited here, for example, it can be one or more.

[0156] The multiple mentioned in the embodiments of the present application refers to a number of two, or more than two.

[0157] The elastic member 3 is connected to the drum 1 and / or the inner door assembly 2, which means that the elastic member 3 can be connected to the drum 1, can also be connected to the inner door assembly 2, or can also be connected to the drum 1 and the inner door assembly 2.

[0158] For example, when there are multiple elastic members 3 , some of the elastic members 3 may be connected to the drum 1 , and another part of the elastic members 3 may be connected to the inner door assembly 2 .

[0159] The specific type of the elastic member 3 is not limited here, and it can be, for example, a spring or an elastic column 31 .

[0160] By setting the length of the elastic member 3, when the angle between the inner door assembly 2 and the first plane is less than a preset angle, the inner door assembly 2 and the drum 1 squeeze the elastic member 3 to cause the elastic member 3 to undergo elastic deformation. If the inner door assembly 2 is locked on the drum 1, the elastic member 3 remains in a deformed state to resist the closed state of the inner door assembly 2. If the inner door assembly 2 is not locked on the drum 1, the elastic member 3 restores the elastic deformation. The force exerted by the elastic member 3 on the inner door assembly 2 causes the inner door assembly 2 to open and drive the outer door assembly 5 from a closed state to an open state.

[0161] In some embodiments, see Figure 7 One side of the inner door assembly 2 has a rotation center, and the elastic member 3 is arranged on a side of the inner door assembly 2 away from the rotation center.

[0162] See also Figure 7 , the rotation center of the inner door assembly is represented by D.

[0163] One side of the inner door assembly 2 has a rotation center, and the inner door assembly 2 is rotatably disposed on the drum 1 through the rotation center to achieve closing and opening of the clothing loading port 1a.

[0164] The elastic member 3 is arranged on a side of the inner door assembly 2 away from the rotation center. The elastic member 3 applies a force to the inner door assembly 2 along the opening direction of the inner door assembly 2, which can form a large torque to open the inner door assembly 2 to a certain angle.

[0165] In some embodiments, see Figure 7 and Figure 8 The clothes processing device further comprises a connecting member 4 having a rotating shaft 41, and the inner door assembly 2 is rotatably connected to the drum 1 through the connecting member 4. The elastic member 3 comprises a torsion spring 32 arranged on the rotating shaft 41. When the angle between the inner door assembly 2 and the first plane is within the range of angle α, the torsion spring 32 applies a force to the inner door assembly 2 in the opening direction of the inner door assembly 2; when the angle between the inner door assembly 2 and the first plane is greater than the range of angle α, the torsion spring 32 applies a force to the inner door assembly 2 in the closing direction of the inner door assembly 2.

[0166] It can be understood that the torsion spring 32 includes a free state, a compressed working state, and a stretched working state. Specifically, the torsion spring 32 includes a first leg and a second leg. The free state refers to the state of the torsion spring 32 when it is not subjected to external force; the compressed working state refers to the torsion spring 32 being subjected to external compression force, so that the distance between the first leg and the second leg is smaller than the distance in the free state; the stretched working state refers to the torsion spring 32 being subjected to external tension, so that the distance between the first leg and the second leg is larger than the distance in the free state.

[0167] Therefore, the torsion spring 32 can be in a compressed working state to form a force on the inner door assembly 2 along the opening direction of the inner door assembly 2 (or a force on the inner door assembly 2 along the closing direction of the inner door assembly 2), or it can be in a stretched working state to form a force on the inner door assembly 2 along the opening direction of the inner door assembly 2 (or a force on the inner door assembly 2 along the closing direction of the inner door assembly 2), and there is no limitation here.

[0168] It can be understood that when the inner door assembly 2 switches between the closing direction and the opening direction, the direction of the force applied by the torsion spring 32 to the inner door assembly 2 is opposite, that is, there is a critical point in the opening angle. At this critical point, the torque applied by the torsion spring 32 to the inner door assembly 2 is, and the torsion spring 32 is in a free state.

[0169] Exemplarily, in some embodiments, the first leg of the torsion spring 32 presses on the drum 1 (or the door hinge 42), and the second leg presses on the inner door assembly 2 (or the reinforcement plate of the inner door 21). When the angle between the inner door assembly 2 and the first plane is less than a preset angle, the torsion spring 32 is in a compressed working state, and applies a force to the inner door assembly 2 along the opening direction of the inner door assembly 2 (to resist the closing state of the inner door assembly). When the angle between the inner door assembly 2 and the first plane is greater than the preset angle, the torsion spring 32 is in a stretched working state, and applies a force to the inner door assembly 2 along the closing direction of the inner door assembly 2 (to resist the opening state of the inner door assembly).

[0170] In other embodiments, the first leg of the torsion spring 32 presses on the box body 6, and the second leg presses on the inner door assembly 2 (or the reinforcement plate of the inner door 21). When the angle between the inner door assembly 2 and the first plane is less than the preset angle, the torsion spring 32 is in a stretched working state and applies a force to the inner door assembly 2 along the opening direction of the inner door assembly 2. When the angle between the inner door assembly 2 and the first plane is greater than the preset angle, the torsion spring 32 is in a squeezed working state and applies a force to the inner door assembly 2 along the closing direction of the inner door assembly 2.

[0171] In some embodiments, the elastic member 3 also includes an elastic column 31, one end of the elastic column 31 is connected to the inner door assembly 2, and the other end extends in a direction away from the inner door assembly 2. When the angle between the inner door assembly 2 and the first plane is within the angle α, the inner door assembly 2 and the roller 1 squeeze the elastic column 31 to cause the elastic column 31 to undergo elastic deformation. The elastic column 31 restores the elastic deformation and applies a force to the inner door assembly 2 to resist the closed state of the inner door assembly 2.

[0172] See also Figure 7 and Figure 8 In this embodiment, the elastic member 3 includes a torsion spring 32 and an elastic column 31. That is to say, by simultaneously arranging the torsion spring 32 and the elastic column 31, when the angle between the inner door assembly 2 and the first plane is within the angle α, the torsion spring 32 and the elastic column 31 simultaneously apply a force to the inner door assembly 2 to jointly resist the closing state of the inner door assembly 2, which is more conducive to avoiding the situation where the inner door assembly 2 is half-closed on the drum 1.

[0173] In some embodiments, the automatic opening unit includes a first magnetic member and a second magnetic member, the first magnetic member is disposed on the inner door assembly 2, and the second magnetic member is disposed on the drum 1. Within the range of angle α, the first magnetic member and the second magnetic member repel each other to resist the closed state of the inner door assembly 2. When the inner door assembly 2 is in the closed state, the repulsive force between the first magnetic member and the second magnetic member is less than the locking force of the inner door assembly 2. When the inner door assembly 2 is in the open state, the repulsive force between the first magnetic member and the second magnetic member causes the inner door assembly 2 to open to drive the outer door assembly 5 from the closed state to the open state.

[0174] The automatic opening unit is provided with a first magnetic member and a second magnetic member, and when the angle between the inner door assembly 2 and the first plane is within the range of angle α, the first magnetic member and the second magnetic member repel each other to resist the closed state of the inner door assembly 2. If the inner door assembly 2 is locked on the drum 1, the repulsive force between the first magnetic member and the second magnetic member is less than the locking force of the inner door assembly 2 locked on the drum 1, that is, the repulsive force between the first magnetic member and the second magnetic member cannot switch the inner door assembly 2 from the closed state to the open state, and if the inner door assembly 2 is not locked on the drum 1 (for example, it is half-closed on the drum 1), the repulsive force between the first magnetic member and the second magnetic member pushes the inner door assembly 2 to open until driving the outer door assembly 5 from the closed state to the open state.

[0175] In some embodiments, obtaining the state of the outer door assembly includes:

[0176] If the in-place detection device detects that the outer door assembly is in a closed state, the in-place information is output;

[0177] If the arrival detection device detects that the outer door assembly is in an open state, it outputs a door closing abnormality alarm message.
