Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular provides a clothing processing device and a control method thereof. Background Art

[0002] A drum washing machine is a type of device that washes clothes based on the principle of beating with a mallet. Compared with a pulsator washing machine, a drum washing machine causes less wear and tear on clothes and saves water.

[0003] Since the inner drum of a drum washing machine needs to rotate along a horizontal axis, the door assembly of the drum washing machine is usually set on the side of the machine body. During the washing process, the user cannot open the door assembly to add clothes, and foam may drip onto the floor through the gap of the door assembly during the washing process. On the other hand, the user needs to bend down to take the washed clothes, and the clothes may accidentally fall onto the floor. This brings a bad user experience.

[0004] Accordingly, the art needs to provide a new technical solution to solve the above problems. Summary of the invention

[0005] In order to at least partially overcome the above-mentioned defects, the present invention is proposed. Specifically, the present invention provides a clothes processing device that can at least partially solve the technical problems that clothes cannot be added during washing, foam overflows during washing, and clothes are easily dropped when being taken out and put in.

[0006] A first aspect of the present invention provides a clothing processing device, comprising: a shell, an outer drum arranged in the shell, and an inner drum rotatably arranged in the outer drum, the shell having a clothing taking-in and putting-out opening at a position corresponding to the inner drum, the shell being provided with a door body assembly capable of closing or opening the clothing taking-in and putting-out opening at a position corresponding to the clothing taking-in and putting-out opening, the clothing processing device further comprising: a blocking portion, which is arranged at a position of the shell corresponding to the clothing taking-in and putting-out opening, so that: when the door body assembly is in a state of opening the clothing taking-in and putting-out opening, the blocking portion can cooperate with the door body assembly, the outer drum and / or the shell to form a structure for blocking water in the inner drum and / or the outer drum from overflowing.

[0007] It can be seen that in this example, with the help of the blocking part, even when there is water in the inner drum, such as when the clothing processing device is in the washing stage, the user can open the door assembly and add clothes. At the same time, the structure formed by the blocking part to block water overflow can also block clothes that accidentally fall during the process of taking and placing clothes to a certain extent, reducing the probability of them falling to the ground. On the other hand, since the blocking part is arranged at the position of the shell corresponding to the clothing taking and placing opening, when the door assembly is in a state where the clothing taking and placing opening is closed, the blocking part can also play a certain blocking role on the water, foam, etc. at the location, reducing the probability of liquid dripping from the door assembly during the operation of the clothing processing device.

[0008] In a technical solution of the above-mentioned clothing processing device, the door assembly is configured to be able to flip toward the direction of gravity to open the clothing access opening, or the door assembly is configured to be able to move in a direction away from the shell to open the clothing access opening.

[0009] Through such a configuration, several possible configurations of the door assembly are provided. The advantage of configuring the door assembly to be able to flip toward the direction of gravity to open the access opening is that there is no need to reserve a large moving space for the door assembly, and it is more convenient for the user to operate the door assembly to move. The advantage of configuring the door assembly to be able to move in a direction away from the housing to open the access opening is that when the door assembly is in the state of opening the access opening, the user has a large space to take and put clothes, and water in the drum will not overflow due to misoperation.

[0010] In a technical solution of the above-mentioned clothing processing device, the shell has a receiving groove at a position corresponding to the door assembly, and when the door assembly is in a state of closing the clothing access opening, the blocking portion is accommodated in the receiving groove.

[0011] With such a structure, it is possible to prevent the barrier from being exposed to the outside of the housing for a long time, or from being in contact with the water in the inner drum and the outer drum for a long time, thereby ensuring its service life. In addition, in such a structure, when the door assembly is in a state of closing the clothing access opening, the receiving groove and the barrier portion received therein can form a sealing layer, effectively preventing liquid from overflowing from the gap between the door assembly and the housing during the operation of the clothing processing device.

[0012] In a technical solution of the above-mentioned laundry processing apparatus, the receiving tank has a first opening capable of being in fluid communication with a water inlet of the housing, so that water is introduced into the receiving tank through the first opening and the blocking portion is rinsed.

[0013] With such a configuration, water can be introduced into the containing tank to rinse the blocking portion, thereby preventing chemical substances from remaining in the blocking portion.

[0014] In a technical solution of the above-mentioned clothes processing device, the clothes processing device includes a fan, at least a part of which is aligned with the first opening so as to introduce wind into the receiving groove through the first opening and ventilate the blocking portion.

[0015] With such a structure, the moisture remaining on the surface of the barrier portion after being rinsed can be removed, thereby preventing the growth of mold and the generation of odor.

[0016] In a technical solution of the above-mentioned clothing processing device, it is characterized in that the accommodating groove has a second opening, and the second opening is fluidically connected to the internal space of the inner drum and / or the outer drum.

[0017] Through such a structure, on the one hand, the flushing water can be introduced into the inner drum to participate in the subsequent washing process, thereby avoiding the waste of water resources. On the other hand, the clothes in the inner drum can be ventilated to avoid the generation of odors and the like.

[0018] A second aspect of the present invention provides a control method for a clothing processing device, the clothing processing device comprising: a shell, an outer drum arranged in the shell, and an inner drum rotatably arranged in the outer drum, the shell having a clothing taking-in and putting-out opening at a position corresponding to the inner drum, the shell being provided with a door body assembly capable of closing or opening the clothing taking-in and putting-out opening at a position corresponding to the clothing taking-in and putting-out opening, the clothing processing device further comprising: a blocking portion, which is arranged at a position of the shell corresponding to the clothing taking-in and putting-out opening, so that: when the door body assembly is in a state of opening the clothing taking-in and putting-out opening, the blocking portion can cooperate with the door body assembly, the outer drum and / or the shell to form a structure for blocking water in the inner drum and / or the outer drum from overflowing; wherein the operation stage of the clothing processing device includes a washing stage, and the method comprises: during the operation of the clothing processing device, in response to request information of a clothing adding operation, determining the current operation stage of the clothing processing device; when the clothing processing device is currently in the washing stage, allowing the door body assembly to be operated to open so as to open the taking-in and putting-out opening.

[0019] Through such a structure, users can add clothes during the washing process, improving the user experience.

[0020] In a technical solution of the above method, the method includes: in response to feedback information that the laundry adding operation has been completed, allowing water to enter the laundry processing device so as to: rinse the blocking part.

[0021] With such a structure, it is possible to avoid residual chemical substances such as detergent, softener, disinfectant, etc. on the surface of the blocking part, thereby extending the service life of the blocking part.

[0022] In a technical solution of the above method, the clothing processing device includes a fan, and the operation stage of the clothing processing device includes a spin-drying stage. The method includes: after the "allowing water to enter the clothing processing device" is completed, and / or after the spin-drying stage, operating the fan so as to: ventilate the blocking part.

[0023] With such a configuration, it is possible to prevent the moisture remaining in the barrier from growing mold, generating odor, and the like.

[0024] In a technical solution of the above method, the method includes: in response to feedback information that the clothing adding operation has been completed, sending a prompt message to add clothing treatment agent and / or extend the washing stage.

[0025] Through such a structure, it can be ensured that the clothes added by the user in the middle of the washing stage can also achieve a better washing effect.

[0026] A third aspect of the present invention provides a computer-readable storage medium, which is suitable for storing multiple program codes, and the program codes are suitable for being loaded and run by a processor to execute the method described in any of the above technical solutions.

DETAILED DESCRIPTION

[0035] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0036] An embodiment of the present invention provides a clothes processing device. Figure 1 is a front view of a clothes processing device according to an embodiment of the present invention, Figure 2 yes Figure 1 An axonometric view of a laundry treatment device in FIG. Figure 3 yes Figure 1 A cross-sectional view of the clothing processing device in the embodiment of the present invention when the door assembly is in a state where the clothing access opening is opened, Figure 4 yes Figure 1 A cross-sectional view of the laundry processing device in the embodiment of the present invention when the door assembly is in a state of closing the laundry access opening. Figure 1-Figure 4 The clothes processing device of this embodiment includes a housing 1, an outer drum 21 disposed in the housing 1, and an inner drum 22 rotatably disposed in the outer drum 21. The specific arrangement of the outer drum 21 and the inner drum 22 here can refer to the drum type clothes processing devices such as drum washing machines in the prior art of the art, and will not be repeated here.

[0037] The housing 1 has a clothing access opening 11 for taking out and putting out clothing at a position corresponding to the inner drum 21, and the user can put clothing into the inner drum 22 or take clothing out of the inner drum 22 through the clothing access opening 11. Furthermore, the housing 1 is provided with a door assembly 3 at a position corresponding to the clothing access opening 11, which can close or open the clothing access opening 11.

[0038] Generally speaking, the inner drum 22 needs to rotate around a horizontal axis when working. Therefore, the clothing access port 11 needs to be set on the side wall of the shell 1. Correspondingly, the door body assembly 3 also needs to be set on the side wall of the shell 1. This leads to the above-mentioned technical problems of being unable to add clothes midway, foam easily overflowing, and clothes being easily dropped when being taken out and placed.

[0039] Based on this, the blocking portion 4 is further provided in this embodiment. Specifically, referring to Figure 3 and Figure 4The blocking portion 4 can be arranged at a position of the shell 1 corresponding to the clothing access opening 11. When the door body assembly 3 is in a state of opening the clothing access opening 11, the blocking portion 4 can cooperate with the door body assembly 3, the outer tube 21 and / or the shell 1 to form a structure that blocks water in the inner tube 22 or the outer tube 21 from overflowing.

[0040] It can be seen that in this example, with the help of the blocking portion 4, even when there is water in the inner drum 22, such as when the clothing processing device is in the washing stage, the user can open the door assembly 3 and add clothes. At the same time, the structure formed by the blocking portion 4 to prevent water from overflowing can also block the clothes that accidentally fall during the process of taking and putting clothes, and reduce the probability of them falling to the ground. On the other hand, since the blocking portion is arranged at the position of the shell 1 corresponding to the clothing taking and putting port 11, when the door assembly 3 is in a state of closing the clothing taking and putting port 11, the blocking portion 4 can also play a certain role in blocking the water, foam, etc. at the location, and reduce the probability of liquid dripping from the door assembly 3 during the operation of the clothing processing device.

[0041] As an example, a part of the structure of the blocking portion 4 can be a plate-like structure, which can be connected to the bottom and two sides of the door body assembly 3 on the one hand, and can be connected to the shell 1 on the other hand. Thus, when the door body assembly 3 is in a state of opening the clothing access port 11, the door body assembly 3 and the blocking portion 4 can cooperate to form a groove-like structure with an opening at the top. When the door body assembly 3 opens the clothing access port 3, water in the inner drum 22 and the outer drum 21 will enter and be retained in the groove-like structure, and the user can take and place clothes through the top opening of the groove-like structure.

[0042] As another example, a part of the structure of the blocking portion 4 can be a plate-like structure, both ends of which are connected to the housing 1. When the door assembly 3 is in a state of opening the clothing access opening 11, the blocking portion 4 can close the lower half of the clothing access opening 11, thereby preventing water from overflowing, and the user can take and put clothes through the upper half of the clothing access opening 11 that is not closed. Further, when there is no water in the inner drum 22, the blocking portion 4 can open the lower half of the clothing access opening 11, thereby facilitating the user to take and put clothes before or after washing.

[0043] Furthermore, at least part of the material of the blocking portion 4 may be a hydrophobic material to ensure that it has good water-blocking performance and a long service life. The specific setting of the blocking portion 4 may be determined according to the movement mode of the door body assembly 3 .

[0044] It is understandable that the structural form of the blocking part 4 is not limited thereto, and those skilled in the art may specifically set the structural form of the blocking part 4 according to the structural forms of components such as the door assembly 3 and the housing 1, as long as it can effectively prevent water from overflowing.

[0045] In a possible embodiment, as described above, the blocking portion 4 is connected to the door assembly 3 on one hand, and to the housing 1 on the other hand. In this case, the door assembly 3 can be configured to be able to flip toward the direction of gravity to open the clothing access opening 11. For example, the bottom of the door assembly 3 can be connected to the housing 1 through a connecting structure such as a rotating shaft, so that it can be flipped. Figure 2 When the door assembly 3 is in the state of opening the clothing access opening 11, the blocking portion 4 and the door assembly 3 cooperate to form a groove structure, thereby preventing water from overflowing. The advantage of this embodiment is that there is no need to reserve a large moving space for the door assembly 3, and at the same time, it is more convenient for the user to operate the door assembly 3 to move.

[0046] It is understandable that in this embodiment, if the door assembly 3 is flipped at a large angle, for example, flipped to a state substantially parallel to the ground, the blocking portion 4 and the door assembly 3 will not be able to effectively prevent water from overflowing.

[0047] To this end, in a possible implementation, the angle range in which the door assembly 3 can be flipped can be related to the amount of water in the inner tube 22 and the outer tube 21. When the amount of water is small, the door assembly 3 can be allowed to flip within a larger angle range, and when the amount of water is large, the door assembly 3 is only allowed to flip within a smaller angle range to ensure that the door assembly 3 and the blocking portion 4 can effectively overflow water. In this case, the angle range in which the door assembly 3 can be flipped can be specifically limited and adjusted by the above-mentioned connecting structure such as the rotating shaft, or the angle range in which the door assembly 3 can be flipped can be limited and adjusted by providing a movable stop structure at the rotating shaft.

[0048] In a possible implementation, the maximum reversible angle of the door assembly 3 can be determined according to the maximum water volume of the inner cylinder 22 and the outer cylinder 21, and the door assembly 3 can be set to be reversible only within the range of the maximum reversible angle. The advantage of this implementation is that it can prevent water overflow caused by user misoperation. In this case, a suitable connection structure can be selected to limit the maximum reversible angle of the door assembly 3, or the maximum reversible angle of the door assembly 3 can be limited by selecting a blocking portion 4 of a suitable size.

[0049] In a possible embodiment, when the blocking portion 4 is connected to the housing 1 on the one hand and to the door assembly 3 on the other hand, the door assembly 3 can also be configured to be movable in a direction away from the housing 1 to open the clothing access opening 11. In this case, the blocking portion 4 and the door assembly 3 can together form a drawer-type structure, and the user can open or close the clothing access opening 11 by pulling the door assembly 3. The advantage of this embodiment is that when the door assembly 3 is in a state of opening the clothing access opening 11, the user has a larger space to take and put clothes, and water will not overflow due to misoperation. However, correspondingly, a larger moving space needs to be reserved for the door assembly 3. On the other hand, in this case, when the door assembly 3 is in an open state, the blocking portion 4 needs to form a bottom wall of a groove-like structure, which requires the blocking portion 4 to have sufficient structural strength to withstand the gravity of the water.

[0050] In a possible implementation, the housing 1 has a receiving groove 12 at a position corresponding to the door assembly 3, and when the door assembly 3 is in a state of closing the clothing access opening 11, the blocking portion 4 can be accommodated in the receiving groove 12. Specifically, the receiving groove 12 can be formed by a depression of the housing 1, and its shape can be adapted to the blocking portion 4 and / or the door assembly 3. For example, when the main body of the door assembly 3 is circular, the receiving groove 12 can be an annular groove.

[0051] With such a structure, it is possible to prevent the blocking portion 4 from being exposed to the outside of the housing 1 for a long time, or from being in contact with the water in the inner drum 22 and the outer drum 21 for a long time, thereby ensuring its service life. In addition, in such a structure, when the door assembly 3 is in a state of closing the clothing access opening 11, the receiving groove 12 and the blocking portion 4 accommodated therein can form a sealing layer, effectively preventing the liquid from overflowing from the gap between the door assembly and the housing during the operation of the clothing processing device.

[0052] In other possible implementations, the shell 1 may also have an opening corresponding to the blocking portion 4 , and when the door assembly 3 is in a state of closing the clothing access opening 11 , the blocking portion 4 may be accommodated in the internal space of the shell 1 .

[0053] In a possible implementation, the blocking portion 4 may be a foldable structure, and when the door assembly 3 is in a state of closing the clothing access opening 11, it may be in a folded state and accommodated in the receiving groove 12. The advantage of this structure is that the volume of the receiving groove 13 can be effectively reduced, and the problem of the inner drum 22 being restricted in its movement and the clothing processing device having a larger volume due to the excessive space occupied by the receiving groove 13 is avoided.

[0054] As an example, see Figure 2The blocking part 4 may include multiple skeletons 41 and a flexible hydrophobic layer 42 connected to the skeleton 41. The skeleton 41 may be a rigid structure, and the multiple skeletons 41 may move relative to each other. One end of the hydrophobic layer 42 may be fixedly connected to the receiving groove 12, and the other end may be fixedly connected to the door body assembly 3. When the door body assembly 3 is opened, the hydrophobic layer 42 is unfolded, and drives the multiple skeletons 41 connected thereto to move so that the spacing between the multiple skeletons 41 increases. Under the support of the multiple skeletons 41, the hydrophobic layer 41 forms the wall surface of the above-mentioned groove-shaped structure, thereby achieving a water-blocking effect. When the door body assembly 3 is closed, the spacing between the multiple skeletons 41 decreases, so that the hydrophobic layer 42 is folded. The advantage of this structure is that the skeleton 41 itself is a rigid structure, so that the blocking part 4 has a good structural strength and can better withstand the pressure of the water gushing out of the outer cylinder 21 and the inner cylinder 22.

[0055] Furthermore, in this embodiment, the shape of the skeleton 41 can be adapted to the contour of the door body assembly 3. Since the opening of the inner tube 22 is circular, the loading port 11 and the door body assembly 3 are usually also configured to be circular. In this case, the accommodating groove 12 can be configured to be an annular structure, and the multiple skeletons 41 can be an arc structure adapted to the contour of the door body assembly 3.

[0056] Furthermore, in this embodiment, the hydrophobic layer 41 may be sealed and connected to the receiving groove 13 and the door assembly 4 to enhance its water-blocking effect and enhance its ability to prevent foam from overflowing when it is received in the receiving groove 12 .

[0057] Obviously, those skilled in the art can also set the blocking part 4 to other types of foldable structures. For example, the above-mentioned frame itself can be set to a foldable structure, one end of which can be connected to the door body assembly 3 and the other end can be connected to the accommodating groove 12.

[0058] In a possible embodiment, the blocking portion 4 can be configured as a rigid structure, which can be slidably connected to the receiving groove 12. Compared with the folding structure, this embodiment can effectively increase the structural strength and service life of the blocking portion 4, but the receiving groove 12 needs to occupy a larger space and may squeeze the range of motion of the inner cylinder 22. Those skilled in the art can choose from the above embodiments according to actual needs, and will not be repeated here.

[0059] In one possible implementation, refer to Figure 3 and Figure 4 The receiving tank 12 may have a first opening 121 , and the first opening 121 may be fluidically connected to the water inlet 13 of the housing 1 , so that water can be introduced into the receiving tank 12 through the first opening 121 to flush the blocking portion 4 .

[0060] It is understandable that when the user moves the door assembly 3 to add clothes during the washing process, the water gushing out from the inner drum 22 and the outer drum 21 comes into contact with the blocking part 4. At this time, the water may be mixed with chemical substances such as detergents, softeners, and disinfectants. When the user closes the door assembly 3, these chemical substances may remain on the surface of the blocking part 4. Especially when the blocking part 4 is set to a folding structure, chemical substances are very likely to remain in the folds formed by the folding. In the long run, the service life of the blocking part 4 may be affected, and map-like stains may be formed on the surface of the blocking part 4, which brings a bad user experience.

[0061] To this end, in this embodiment, a first opening 121 is provided on the receiving groove 12 , and the first opening 121 is fluidically connected to the water inlet 13 of the shell 1 , so that water can be introduced into the receiving groove 12 to rinse the blocking portion 4 and avoid chemical residues in the blocking portion 4 .

[0062] In a possible implementation, the water inlet 13 may be a water inlet for introducing water into the outer cylinder 21 and the inner cylinder 22. In other words, the water inlet originally provided by the housing 1 may be used without the need to provide a new water inlet, thereby saving costs and facilitating installation. Figure 3 and Figure 4 The water inlet pipe 131 at the water inlet 13 can form two branches, wherein the first branch 1311 can be fluidically connected to the outer cylinder 21, and the second branch 1322 can be fluidically connected to the first opening 121. A valve, such as a solenoid valve, can be set in each of the two branches, and the flow direction of water can be controlled by controlling the opening and closing of the valve, so that water can be introduced into the outer cylinder 21 alone, or water can be introduced into the containing tank 12 alone, or water can be introduced into both at the same time.

[0063] In a possible embodiment, the first opening 121 can be arranged above the blocking portion 4, for example, arranged on the top wall of the receiving groove 12, so that the water at the first opening 121 will flow downward along the blocking portion 4 under the action of gravity, thereby flushing it. In a possible embodiment, it can be understood that both sides of the door body assembly 3 have the blocking portion 4, so two first openings 121 can be arranged, and they are respectively located above the blocking portion 4 on both sides of the door body assembly 3. In addition to the above-mentioned setting, those skilled in the art can also set the first opening 121 at other suitable positions according to actual needs, which will not be repeated here.

[0064] In a possible implementation, a nozzle may be provided at the first opening 121 , and water may be sprayed onto the blocking portion 4 by means of the nozzle, thereby improving the flushing effect and further avoiding the residue of chemical substances.

[0065] Obviously, in addition to the above-mentioned method, those skilled in the art may also adopt other suitable structures to clean the blocking part 4. For example, the clothing processing device may include a cleaning component, which can be connected to the water inlet of the shell 1, and at least a part of its structure can be aligned with the blocking part 4 to clean it.

[0066] In a possible implementation, reference may still be made to Figure 3 and Figure 4 , the clothes processing device may include a fan 5, at least a part of the structure of the fan 5 (such as the air outlet) may be aligned with the first opening 121, so that the wind can be introduced into the receiving groove 12 through the first opening 121 to ventilate the blocking portion 4. In this case, a three-way structure may be provided at the first opening 121, one of the openings of the three-way structure is connected to the second branch 1322, and the other opening is connected to the air duct 51 of the fan 5. Obviously, multiple first openings 121 may also be provided, a part of the first openings 121 is in fluid communication with the water inlet 13, and the fan 5 is aligned with another part of the first openings 121, and those skilled in the art may make a selection according to actual needs.

[0067] It is understandable that flushing the barrier portion 4 can avoid chemical residues, but after flushing, there will still be water residue on the surface of the barrier portion 4. Over time, it is easy for mold to grow on the surface of the barrier portion 4 and produce odor. For this reason, in this embodiment, a fan 5 is further provided, and the wind generated by the fan 5 when it is running is introduced into the receiving groove 13 by means of the first opening 121 to dry the barrier portion 4 to avoid water residue.

[0068] Obviously, in addition to the above-mentioned method, those skilled in the art may also adopt other methods to guide the wind generated by the fan 5 to the location of the blocking portion 4, so as to ventilate it.

[0069] Furthermore, in the above embodiment, the receiving tank 13 may also have a second opening 122 , which may be disposed at the bottom of the receiving tank 12 , and the water after flushing the blocking portion 4 may leave the receiving tank 12 through the second opening 122 .

[0070] In a possible embodiment, the second opening 122 can be configured to be in fluid communication with the inner drum 22 or the outer drum 21, so that the water after flushing the barrier 4 can flow into the inner drum 22 through the second opening 122 to participate in the subsequent washing process, thereby avoiding the waste of water resources. At the same time, when the barrier 4 is ventilated, the clothes in the inner drum 22 can also be ventilated to prevent them from breeding mold and generating odor. In other possible embodiments, the second opening 122 may not be in fluid communication with the inner drum 22 or the outer drum 21, but may be directly in fluid communication with the sewer pipe of the clothing treatment device. Those skilled in the art can make specific arrangements according to actual needs.

[0071] An embodiment of the present invention further provides a control method for the laundry processing device described above, referring to Figure 5 , the control method comprises:

[0072] Step S501: during the operation of the laundry treatment device, in response to request information for a laundry adding operation, determining the current operation stage of the laundry treatment device.

[0073] Step S502: When the laundry processing apparatus is currently in the washing stage, the door assembly is allowed to be operated to open so as to open the laundry access opening.

[0074] As is common knowledge in the art, the operation phases of a clothing processing device generally include a washing phase, a rinsing phase, a spin-drying phase, and the like. In this example, the user can send a request message for a clothing adding operation by pressing a control button on the clothing processing device or using a mobile client, and in response to the request message for the clothing adding operation, the current operation phase of the clothing processing device can be determined. If the clothing processing is currently in a working state such as rinsing or spin-drying, the user is not allowed to move the door assembly 3 to open the clothing access port 11, because the washing phase has ended at this time, and adding clothing at this time cannot guarantee that the added clothing will obtain a better cleaning effect. If the clothing processing device is currently in the washing phase, it can be considered that the current working state of the clothing processing device meets the predetermined requirements, and therefore the door assembly 3 can be allowed to be operated to open the clothing access port.

[0075] In a possible implementation, an electromagnetic lock may be provided at the door assembly 3 of the clothing processing device. If the current working state of the clothing processing device meets the predetermined requirements, the electromagnetic lock may be unlocked, so that the door assembly 3 is operated to be opened. After the door assembly 3 is closed again, the electromagnetic lock may be locked again. In other implementations, the clothing processing device may not be provided with an electromagnetic lock, and may only send a prompt message allowing the door assembly 3 to be opened.

[0076] In a possible implementation, when it is determined that the current operation stage of the laundry processing device is the washing stage, the current rotation speed of the inner drum 22 can be further determined. If the current rotation speed of the inner drum 22 is greater than a set value, the rotation speed of the inner drum 22 is reduced to the set value before the door assembly 3 is allowed to be operated to open. If the current rotation speed of the inner drum 22 is less than or equal to a predetermined value, the door assembly 3 can be directly allowed to be operated to open.

[0077] It can be understood that although the blocking portion 4 can prevent water from overflowing, when the rotation speed of the inner drum 22 is high, the turbulence generated by the water flow is large, and some water may overflow. For this reason, in this example, when the rotation speed of the inner drum 22 is greater than a predetermined value, the door body assembly 3 is not allowed to be operated to open, so as to avoid the above situation.

[0078] In a possible implementation, in response to feedback information that the laundry adding operation has been completed, the laundry processing device may be controlled to perform a water intake operation, thereby introducing water into the containing tank 12 to rinse the blocking portion 4 .

[0079] As described above, when the door assembly is in a state of closing the clothing access opening 11, the blocking portion 4 can be accommodated in the receiving groove 12, and the receiving groove 12 can have a first opening 121, and the first opening 121 can be fluidically connected to the water inlet 13 of the housing 1. In this case, water can be introduced into the receiving groove 12 through the first opening 121 to clean the blocking portion 4. Obviously, those skilled in the art can also adopt other structures to achieve the cleaning of the blocking portion 4. For example, the clothing processing device can include a cleaning component, and the blocking portion 4 can be cleaned by means of the cleaning component.

[0080] In this example, it can be determined whether the user has completed the clothing adding operation by detecting the position of the door assembly 3, or it can be determined whether the user has completed the clothing adding operation by detecting the state of the locking structure at the door assembly 3. Further, after determining that the user has completed the clothing adding operation, the clothing processing device can be immediately controlled to perform the water intake operation, or it can be controlled to perform the water intake operation after the clothing processing device enters the rinsing stage, so that water is introduced into the containing tank 12 and the outer drum 21 at the same time. Those skilled in the art can make settings according to actual needs, and there is no limitation on this.

[0081] In a possible implementation, as described above, the laundry treatment device may include a fan 5. In this case, the method may include: after the above-mentioned "allowing water to enter the laundry treatment device" is completed, and / or after the spin-drying stage of the laundry treatment device is completed, operating the fan, so as to ventilate the blocking portion 4.

[0082] As described above, at least a portion of the fan 5 can be aligned with the first opening 121 of the receiving slot 12, so as to introduce wind into the receiving slot 12 to ventilate the blocking portion 4. Obviously, those skilled in the art can also use other structures to guide the wind generated by the fan 5 to the blocking portion 4 to ventilate it.

[0083] In this example, the fan 5 can be turned on for ventilation immediately after the water intake operation is completed, or ventilation can be performed after the spin-drying stage structure. As described above, in some embodiments, the receiving tank 12 has a second opening 122 that is fluidly connected to the outer drum 21 or the inner drum 22. In this case, preferably, ventilation is performed after the spin-drying stage is completed, so that the clothes that have been washed in the inner drum 22 can be ventilated at the same time, thereby achieving the technical effect of preventing mildew and removing odor.

[0084] In a possible implementation, in response to feedback information that the clothing adding operation has been completed, a reminder message for adding detergent and / or extending the washing stage can be sent, thereby reminding the user to add clothing treatment agents or extend the washing stage. The reminder message can be sent to the user terminal, or the reminder message can be sent to the audio, display and other components of the clothing treatment device, and presented to the user in the form of text, images, voice broadcasts, etc., without limitation. Through such a configuration, the clothing added by the user during the washing stage can also achieve a better washing effect.

[0085] The method described above can be executed by a controller of a clothing processing device. Specifically, the controller may include multiple control modules, and the "control module" may include hardware, software, or a combination of the two. A module may include a hardware circuit, various suitable sensors, communication ports, and memory, and may also include a software part, such as a program code, or a combination of software and hardware. The processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor, or any other suitable processor. The processor has data and / or signal processing functions. The processor may be implemented in software, hardware, or a combination of the two. Non-temporary computer-readable storage media include any suitable media that can store program codes, such as a disk, a hard disk, an optical disk, a flash memory, a read-only memory, a random access memory, and the like.

[0086] Further, it should be understood that since the setting of the control module is only for illustrating the functional unit corresponding to the control method of the present invention, the physical device corresponding to the control module can be the processor itself, or a part of the software in the processor, a part of the hardware, or a part of the combination of software and hardware. Therefore, the number of control modules is only one and is only schematic. It can be understood by those skilled in the art that the control module can be adaptively split according to actual conditions.
