DETAILED DESCRIPTION

[0056] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0057] Currently available washing machines are unable to simultaneously wash clothes and shoes. The present invention provides a washing drum assembly and laundry processing device that, by controlling the engagement and disengagement of a magnetic attraction structure between the washing drum and a rotating member, enables a motor to selectively drive one or more of multiple washing drums to rotate during operation.

[0058] The following is combined with Figure 1 -Attached Figure 7 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0059] Example

[0060] like Figure 1-Figure 7 As shown, in a first aspect of this embodiment, a washing drum assembly is provided for use in a clothes processing device, the washing drum assembly comprising:

[0061] A plurality of rotating members 2 driven to rotate by a same motor 1, and a plurality of washing tubs 3 corresponding one to one to the plurality of rotating members 2;

[0062] A magnetic structure 4 is provided between the rotating member 2 and the washing tub 1. The magnetic structure 4 includes a magnetic device 41 and an iron member 42 that can be magnetically coupled together. One of the magnetic device 41 and the iron member 42 is provided on the rotating member 2, and the other is provided on the washing tub 3. The magnetic structure 4 has an engaged state in which the magnetic device 41 and the iron member 42 are attracted together, and a separated state in which the magnetic device 41 and the iron member 42 are separated. When the magnetic structure 4 is in the engaged state, the rotating member 2 and the washing tub 3 are connected as a whole via the magnetic structure 4, so that the washing tub 3 is driven to rotate when the rotating member 2 rotates. When the magnetic structure is in the separated state, the rotating member 2 and the washing tub 3 are separated, and the rotating member 2 does not drive the washing tub 3 to rotate when it rotates.

[0063] There are multiple magnetic structures 4, and the multiple magnetic structures 4 are arranged in one-to-one correspondence with the multiple rotating parts 2 and the multiple washing drums 3. The multiple magnetic structures 4 can be controlled to be attracted or separated individually or simultaneously, so that one or more of the multiple washing drums 3 can be selectively driven to rotate by a motor 1.

[0064] In the embodiment of the present invention, by controlling the attraction and separation of the magnetic attraction structure between the washing tub 3 and the rotating member 2, the motor can selectively drive one or more of the multiple washing tubs 3 to rotate during operation.

[0065] Specifically, such as Figures 1-4 As shown, the top of the rotating member 2 is arranged opposite to the bottom of the washing tub 3;

[0066] One of the magnetic device 41 and the iron member 42 is disposed at the top of the rotating member 2 , and the other is disposed at the bottom of the washing tub 3 .

[0067] Preferably, the magnetic device 41 is arranged at the top of the rotating part 2 , and the iron part 42 is arranged at the bottom of the washing tub 3 .

[0068] like Figures 1-4 As shown, the washing tub 3 is a flexible washing bag of cylindrical structure;

[0069] The washing tub assembly further includes an air suction structure 5 in fluid communication with the washing tub 3, the air suction structure 5 being used to draw gas from the washing tub 3 so as to cause the flexible washing tub 3 to contract;

[0070] When the air suction structure 5 stops sucking air, the flexible washing drum 3 can return to its natural state.

[0071] In the embodiment of the present invention, the washing drum 3 is configured to be flexible and an air suction structure 5 capable of sucking out the air in the washing drum 3 is provided. When the washing drum 3 is sucked in by the air suction structure 5, the washing drum will deform due to negative pressure and squeeze water out of the clothes, thereby completing the dehydration process of the shoes or clothes in the washing drum 3.

[0072] It is worth noting that the washing drum assembly also includes a controller, which is used to control the suction time of the suction structure 5;

[0073] When the air suction time of the air suction structure 5 is greater than the first preset time t1 and less than the second preset time t2, the washing tub 3 can be retracted and the magnetic device 41 and the iron part 42 can be magnetically attracted together;

[0074] The first preset time t1 is greater than 0, and the second preset time t2 is a critical value for separating the magnetic device 41 from the iron component 42 .

[0075] That is, when the magnetic device 41 and the iron part 42 are magnetically attracted together, the washing drum 3 is sucked for a time greater than t1 and less than t2 through the magnetic structure 5, which can not only make the washing drum 3 shrink to squeeze and dehydrate the clothes or shoes in the drum, but also make the washing drum 3 rotate with the rotating part 2, avoiding the separation of the washing drum 3 and the rotating part 2 due to the separation of the magnetic device 41 and the iron part 42.

[0076] Further, if Figure 1 and Figure 2 As shown, the magnetic device 41 is an electromagnet located at the bottom of the washing tub 3 or the top of the rotating member 2;

[0077] When the electromagnet is in the power-off state, there is a distance between the electromagnet and its corresponding iron member 42;

[0078] When the electromagnet is in a powered state, the electromagnet and its corresponding iron part 42 are attracted together.

[0079] Of course, in some alternative embodiments, such as Figure 3 and Figure 4 As shown, the magnetic device 41 can also be a magnetic member provided at the bottom of the washing tub 3 or the top of the rotating member 2, and the magnetic member and its corresponding iron member 42 are attracted together when the washing tub assembly is in the power-off state;

[0080] When the air suction structure 5 sucks the air in the washing tub 3 for more than the second preset time t2, the magnetic part and the iron part 42 can be separated.

[0081] When the magnetic device 41 is an electromagnet, in the initial state (the initial state is the state of the clothes processing device when it is powered off), the magnetic device 41 and the iron component 42 are separated.

[0082] When the magnetic device 42 is a magnetic part, in the initial state {the initial state is the state of the clothing processing device when the power is off}, the magnetic device 41 and the iron part 42 are in an attracted state. When the two need to be separated, the suction structure 5 needs to suck air into the washing drum 3 for more than the second preset time t2. When the suction time exceeds the second preset time t2, the magnetic device 41 and the iron part 42 can be separated.

[0083] In order to more clearly understand the working principle of the washing drum assembly, the working principle of the washing drum assembly is explained below with the magnetic device being an electromagnet and the magnetic device being a magnetic part:

[0084] like Figure 5 As shown, when the magnetic device 41 is an electromagnet, in the initial state {when the system is not powered on}, the iron part 42 and the electromagnet are not in contact with each other. After the electromagnet is powered on, the body block 42 at the bottom of the washing tub 3 is adsorbed and moves downward under the action of the magnetic force until the iron part 42 and the electromagnet are in contact with each other to achieve a common body.

[0085] It is worth noting that when the system does not recognize that the washing drum 3 is open, it determines that there is no load in the washing drum 3, the electromagnet is not energized, the iron part 42 and the electromagnet maintain the initial distance, and are in a disconnected state. The washing drum 3 is disengaged from the rotating part 2, and no rubbing washing operation is performed.

[0086] When it is recognized that the washing tub 3 is open, it is determined that a load is placed in the washing tub 3, the electromagnet is energized, and the air suction structure 5 discharges the air in the washing tub 3 through the vent pipe via the air pump and the reversing valve. The air pump is open for a time greater than the aforementioned t1 and less than the aforementioned t2. During this time, the washing tub 3 will deform under the action of atmospheric pressure, so that the shoes and / or clothes in the washing tub 3 fit more closely to the inner wall of the flexible washing tub 3, thereby enhancing the rubbing washing effect on the shoes and / or clothes.

[0087] like Figure 6 As shown, when the magnetic device 41 is a magnetic part, except in the initial state {when the system is not powered on} the iron part 42 and the magnetic part are in contact with each other, the air suction structure 5 discharges the air in the washing tub 3 through the vent pipe via the air pump and the reversing valve. During this process, the washing tub 3 will be deformed under the action of atmospheric pressure.

[0088] As described above, if the system does not detect that the washing drum 3 is open, it determines that there is no load in the washing drum 3. Therefore, for the unused washing drum 3, the air pump is turned on for a period longer than the second preset time t2, until the iron member 42 and the magnetic member are separated, the washing drum 3 is disengaged from the rotating member, and the kneading washing operation is stopped. This prevents the remaining washing drums from idling when one loaded washing drum rotates.

[0089] When the system detects that the washing tub 3 is open, it determines that a load is placed in the washing tub 3. Therefore, for the washing tub 3 in use, the air pump is turned on for a time greater than the first preset time t1 and less than the second preset time t2, ensuring that the washing tub 3 is flattened but does not separate from the rotating member 2.

[0090] Further, such as Figures 1-4 As shown, the washing drum assembly provided in the embodiment of the present invention also includes an extrusion structure, which can squeeze the outer wall of the washing drum 3 to squeeze and wash the load in the washing drum 3 when the washing drum 3 rotates, so as to improve the washing effect of the clothes and / or shoes in the washing drum.

[0091] The embodiment of the present invention provides two extrusion structures, but is not limited thereto. The two extrusion structures provided in this embodiment are specifically described below:

[0092] The first extrusion structure:

[0093] like Figure 1 and Figure 2 As shown, the extrusion structure includes an air bag 6 arranged on the outer peripheral side of the washing tub 3 and spaced apart from the washing tub 3:

[0094] The washing tub assembly further includes an inflatable structure 7 in fluid communication with the air bag 6, wherein the inflatable structure 7 and the air suction structure 5 share an air pump;

[0095] The inflatable structure 7 is used to inject gas into the airbag 6 to expand the airbag 6 and squeeze the outer peripheral wall of the washing tub 3;

[0096] A plurality of air bags 6 are provided, and the plurality of air bags 6 are evenly distributed on the periphery of the washing tub 3 .

[0097] The second extrusion structure:

[0098] like Figure 3 and Figure 4 As shown, the extrusion structure includes an extrusion member 8, one portion of which is disposed between the magnetic device 41 and the iron member 42, and the other portion of which is disposed on the outer periphery of the washing tub 3;

[0099] The portion of the extrusion member 8 located on the outer peripheral side of the washing tub 3 squeezes the outer peripheral wall of the washing tub 3 when the magnetic device 41 and the iron member 42 are attracted, and separates from the outer peripheral wall of the washing tub 3 when the magnetic device 41 and the iron member 42 are separated.

[0100] Specifically, the extrusion member 8 includes an elastic body 81 of elastic structure and an extrusion head 82 of rigid structure;

[0101] A portion of the elastic body 81 is disposed between the magnetic device 41 and the iron member 42, and another portion of the elastic body 81 extends upward on a curved surface and is connected to an extrusion head 82 disposed on the outer periphery of the washing tub 3;

[0102] When the magnetic device 41 and the iron member 42 are attracted to each other, the elastic body 81 can be squeezed, so that the squeezing head 82 provided on the outer peripheral side of the washing tub 3 is retracted toward one side of the washing tub 3 to squeeze the washing tub 3;

[0103] The elastic body 81 is an elastic member that is generally U-shaped. Two extrusion heads 82 are provided, which are respectively connected to the opposite end surfaces of the opening position of the U-shaped elastic member.

[0104] As mentioned above, when washing clothes and / or shoes, the washing tub assembly determines whether the washing tub 3 is loaded based on the opening state of the washing tub 3 .

[0105] Specifically, such as Figures 1-4 As shown, a load placement port is provided at the top of the washing tub 3, and a sealing cover 31 for sealing the washing tub 3 is provided at the load placement port;

[0106] The controller is used to determine whether a load is placed in the washing tub 3 according to the opening and closing status of the sealing cover 31.

[0107] In any of the above embodiments, Figures 1-4 As shown, the multiple rotating parts 2 and the motor 1 are driven by a belt 9;

[0108] The washing tub assembly further includes a water inlet pipe 100, one end of which is connected to the water inlet valve and the other end of which is connected to the interior of the washing tub 3;

[0109] The washing tub assembly further includes a drain pipe 200 , one end of which is connected to the interior of the washing tub 3 , and the other end of which is connected to the exterior of the washing tub 3 .

[0110] The washing process of the washing drum assembly is described below by taking the washing drum assembly having two washing drums 3 as an example:

[0111] The belt 9 horizontally connects the two washing drums in series. The input shaft of the motor 1 is connected to the rotating member 2 through the belt 9. The input shaft of the motor 9 and the rotating member 2 rotate relative to each other.

[0112] The sealing cover 31 is an openable structure. After closing, the sealing cover 31 can fit tightly against the washing tub 3 to seal the air in the washing tub 3. At the same time, the opening of the sealing cover 31 can be used to identify whether clothes are put into the washing tub 3. If the machine recognizes that the sealing cover 31 is open, it is determined that the load is put in. After closing the sealing cover 31, the machine starts to run, and the washing water enters the washing tub 3 along the water inlet pipe 100 through the water inlet valve; when washing is completed, the washing water flows out of the machine from the drain valve through the drain pipe 200. When dehydrating, the air pump evacuates the washing tub 3 for a long time. Since the flexible bag is a sealed space and the material is flexible, the washing bag will deform under negative pressure to squeeze water out of the clothes, completing the dehydration process of shoes or clothes.

[0113] A second aspect of this embodiment further provides a clothes processing device, which includes the above-mentioned washing drum assembly.

[0114] Specifically, such as Figure 7 As shown, the clothes processing device includes:

[0115] The housing 300 has a housing cavity formed therein and a housing cavity opening formed on a side of the housing cavity;

[0116] The pull-out module 400 is retractable and disposed in the housing cavity through the housing cavity opening. The pull-out module 400 forms an installation cavity with a top opening. The above-mentioned washing tub assembly is installed in the installation cavity, wherein the load placement opening on the washing tub 3 of the washing tub assembly faces upward;

[0117] The top of the drawer module is provided with a mounting plane, on which a mounting piece is provided.

[0118] More specifically, Figure 7 As shown, the washing tub 3 includes a first washing tub 3a and a second washing tub 3b. The first washing tub 3a is used for washing clothes, and the second washing tub 3b is used for washing shoes.
