[0005] Compared with the prior art, the advantages and positive effects of the present invention are as follows: the inner barrel of the washing machine proposed in the present invention comprises a barrel main body consisting of an inner barrel chassis and a plurality of louver sheets, wherein the louver sheets are rotatably fixed on the inner barrel chassis at set intervals, and when the electromagnetic device is energized, the magnets at the top of the louver sheets are in a zero deflection state based on the electromagnetic adsorption force, and all the louver sheets in the zero deflection state are spliced ​​to form a closed inner barrel side wall structure, which can perform washing, rinsing, dehydration and other operations normally after water is filled in; when the electromagnetic device is powered off, the magnets at the top of the louver sheets lose their adsorption force and are in a specified deflection state, and the closed inner barrel side wall structure is converted into an open inner barrel side wall structure; the open inner barrel side wall structure helps to increase the drainage speed, thereby shortening the washing time and speeding up the washing progress; and the open inner barrel side wall structure can increase the ventilation area between the inner and outer barrels when not washing, and can make the moisture remaining between the inner and outer barrels evaporate quickly, thereby avoiding the generation of odor and mold between the inner and outer barrels.

[0006] In some embodiments of the present invention, the magnet installed on the top of the louver sheet includes a first magnet and a second magnet; the first magnet and the second magnet are respectively fixed at two ends of the top of the louver sheet.

[0007] The first magnet and the second magnet respectively fixed at the two ends of the top of the louver sheet can increase the splicing strength between the louver sheets under the action of the electromagnetic adsorption force generated by the electromagnetic device, ensure the strength of the side wall structure of the closed inner barrel, and thus ensure the washing, rinsing and dehydration effects.

[0008] In some embodiments of the present invention, an annular track is provided on the inner barrel bottom plate, and the fixing ring is fixed in the annular track.

[0009] The position of the louver material can be limited from the bottom of the louver material by the annular track, so as to facilitate the installation of the louver material; preferably, the deflection angle of the louver material after losing the electromagnetic adsorption force can be limited by limiting the width of the annular track, that is, limiting the specified deflection angle, and the specified deflection angle determines the opening angle of the louver material and determines the degree of opening of the inner barrel side wall.

[0010] In some embodiments of the present invention, the electromagnetic device is composed of a first electromagnetic coil and a second electromagnetic coil concentrically having different radii; when the first electromagnetic coil is energized, the first electromagnetic attraction force generated on the magnet at the top of the louver material puts the louver material in a zero deflection state; when the first electromagnetic coil is de-energized and the second electromagnetic coil is energized, the second electromagnetic attraction force generated on the magnet at the top of the louver material puts the louver material in a specified deflection state.

[0011] The electromagnetic device is designed in the shape of an electromagnetic coil, and the first electromagnetic coil and the second electromagnetic coil are concentrically assembled. The first electromagnetic adsorption force and the second electromagnetic adsorption force generated by the application of power voltage to the first electromagnetic coil and the second electromagnetic coil have different effects on the louver material. When the first electromagnetic coil is energized, the first electromagnetic adsorption force is generated, so that the louver material is spliced ​​to form a closed inner barrel side wall structure.

[0012] In some embodiments of the present invention, the electromagnetic device is composed of a plurality of electromagnetic units, and each electromagnetic unit corresponds to one or a plurality of louver sheet assemblies.

[0013] Through the discrete structure of several electromagnetic units, the deflection states of different louver materials or different groups of louver materials can be controlled, so as to adapt to different control needs. For example, when draining water, some louver materials are controlled to be in a specified deflection state, which speeds up the drainage while preventing the laundry from entering the outer barrel through the louver materials due to the rapid outward expansion of the water flow; for example, after washing is completed, all louver materials are controlled to be in a specified deflection state to ensure the maximum ventilation area between the inner and outer barrels, effectively preventing the generation of odor and mold in the inner and outer barrels.

When the washing machine performs the tub self-cleaning program, the louver sheet can be controlled to be in a specified deflection state, so that the water flow stirred by the impeller can not only flush the louver sheet, but also flush the inner wall of the outer tub, so that the dirt between the inner and outer tubs can be cleaned more thoroughly, thereby achieving a better tub self-cleaning effect. When the washing machine needs to be repaired, the louver sheet can be controlled to be in a specified deflection state, making repair more convenient.

[0016] In some embodiments of the present invention, the washing machine further comprises a control disc seat installed on the top of the outer tub; and the electromagnetic device is installed on the bottom of the control disc seat.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0031] The inner drum of the washing machine proposed by the present invention is as follows: Figure 1 As shown, it consists of an inner barrel chassis 1 (illustrated as a ring structure in the figure), a plurality of louver sheets 2 and an electromagnetic device 3, wherein the bottoms of the plurality of louver sheets 2 are rotatably fixed on the inner barrel chassis 2 at set intervals, and a magnet 4 is installed on the bottom; the electromagnetic device 3 is assembled at the top of the louver sheet 2.

[0032] In the present invention, when the electromagnetic device 3 is powered on, it generates an electromagnetic adsorption force on the magnets on the top of the louver pieces, so that all the louver pieces are in a zero deflection state and are spliced ​​into a shape as shown in FIG. Figure 2 When the electromagnetic device 3 is powered off, the shutter sheet 2 loses the electromagnetic adsorption force and is in a specified deflection state, forming a closed inner barrel side wall structure as shown; Figure 1 The open inner barrel side wall structure shown.

[0033] Based on the inner barrel of the washing machine proposed by the present invention, when the electromagnetic device is powered on, the magnets on the top of the louver sheets are in a zero deflection state due to the electromagnetic adsorption force, and all the louver sheets in the zero deflection state are spliced ​​to form a closed inner barrel side wall structure, and washing, rinsing, dehydration and other operations can be performed normally after water is filled; when the electromagnetic device is powered off, the magnets on the top of the louver sheets lose their adsorption force and are in a specified deflection state, and the closed inner barrel side wall structure is converted into an open inner barrel side wall structure; the open inner barrel side wall structure helps to increase the drainage speed, thereby shortening the washing time and speeding up the washing progress; and the open inner barrel side wall structure can increase the ventilation area between the inner and outer barrels when not washing, and can make the moisture remaining between the inner and outer barrels evaporate quickly, thereby avoiding the generation of odor and mold between the inner and outer barrels.

[0034] In some embodiments of the present invention, Figure 3As shown, the magnets installed on the top of each louver sheet 2 include a first magnet 41 and a second magnet 42; the first magnet 41 and the second magnet 42 are respectively fixed at the two ends of the top of the louver sheet. When the electromagnetic device 3 is energized, the first magnet 41 is attracted to the electromagnetic device 3 by the electromagnetic adsorption force, and the second magnet 42 is also attracted to the electromagnetic device 3 by the electromagnetic adsorption force. Based on its rotatability, the louver sheet 2 is adsorbed on the electromagnetic device by rotating in a clockwise or counterclockwise direction.

[0035] The two magnets respectively fixed at the two ends of the top of the louver sheet can be adsorbed on the electromagnetic device from both ends of the sheet under the action of the electromagnetic adsorption force generated by the electromagnetic device, thereby increasing the splicing strength between the louver sheets, ensuring the strength of the side wall structure of the closed inner barrel, and further ensuring the washing, rinsing and dehydration effects.

[0036] In some embodiments of the present invention, Figure 4 As shown, an annular track 11 is provided on the inner barrel bottom plate 1, and a plurality of louver sheets 2 are fixed in the annular track 11 through a rotating shaft. The annular track 11 limits the position of the louver sheets 2 from the bottom of the louver sheets 2, and acts as a limiting groove to facilitate the assembly of the louver sheets.

[0037] In some embodiments of the present invention, the deflection state of the shutter material 2 after losing the electromagnetic adsorption force can be limited by setting the width of the annular track 11, that is, the deflection angle of the shutter material 2 when losing the adsorption force is limited. The deflection angle determines the opening angle of the shutter material 2 and also determines the degree of opening of the inner barrel side wall. Specifically, when the width of the annular track 11 is smaller than the width of the shutter material 2, the deflection angle of the shutter material 2 can be limited to within 90 degrees.

[0038] When the electromagnetic device 3 is powered off, the electromagnetic adsorption force disappears, the louver material 2 loses the electromagnetic adsorption force and is in a free state. It may still be in a closed state, or it may be squeezed by the laundry or flushed by the water flow and deflected at a certain angle; when the drainage process is started, under the action of the water flow, the louver materials 2 may be out of order and deflected at different angles, or the louver materials may be damaged due to excessive deflection when the water flow is large. Based on the limitation of the annular track 11 of this embodiment, under the action of large water flow, the maximum deflection angle of each louver material 2 is limited to within 90 degrees, thereby avoiding damage to the louver material 2 and promoting rapid outflow of water through the inclined structure.

[0039] In some embodiments of the present invention, the electromagnetic device 3 is composed of a first electromagnetic coil 31 and a second electromagnetic coil 32 concentrically, and the radii of the first electromagnetic coil 31 and the second electromagnetic coil 32 are different, such as Figure 5In the illustrated embodiment, the radius of the first electromagnetic coil 31 is greater than the radius of the second electromagnetic coil 32, and the two are assembled concentrically. After being energized, the first electromagnetic adsorption force and the second electromagnetic adsorption force are respectively generated on the magnet at the top of the louver sheet. Based on this structure, when the first electromagnetic coil 31 is energized, the first electromagnetic adsorption force causes all louver sheets 2 to be in a zero deflection state and spliced ​​into a closed inner barrel side wall structure; when the second electromagnetic coil 32 is energized, the second electromagnetic adsorption force causes all louver sheets 2 to deflect toward the second electromagnetic coil 32. When the voltage applied to the second electromagnetic coil 32 is controlled, or a limiting structure is added to the louver sheet 2, the deflection angle of the louver sheet can be limited, so that it is limited to a set opening angle and is in a specified deflection state, thereby forming an open inner barrel side wall structure.

[0040] In some embodiments of the present invention, Figure 6 As shown, the electromagnetic device 3 is composed of a plurality of electromagnetic units 33, and each electromagnetic unit 33 corresponds to a louver sheet or a group (plurality) of louver sheets for assembly.

[0041] Through the discrete structure of several electromagnetic units 33, the deflection states of different louver materials or different groups of louver materials can be controlled, so as to adapt to different control requirements. For example, when draining water, some louver materials are controlled to be in a specified deflection state, which speeds up the drainage while preventing the laundry from entering the outer barrel through the louver materials due to the rapid outward expansion of the water flow; for example, after washing is completed, all louver materials are controlled to be in a specified deflection state to ensure the maximum ventilation area between the inner and outer barrels, effectively preventing the inner and outer barrels from generating odor and mold.

[0042] In some embodiments of the present invention, a plurality of electromagnetic units 33 may be spliced ​​together to form an electromagnetic coil structure, or may be installed separately.

[0043] Based on the washing machine inner drum proposed by the present invention, the present invention further proposes a washing machine, in which the washing machine inner drum as described above is installed in the washing machine outer drum, and the electromagnetic device 3 can be fixed to the top of all louver sheets through a fixing ring structure, and can also be installed at the bottom of the control disk seat on the top of the washing machine outer drum.

[0044] The present invention also proposes a washing machine control method in combination with the washing machine, such as Figure 7 As shown, the washing machine control method includes: S1: When a washing instruction or a rinsing process is received, the electromagnetic device is controlled to be energized.

[0045] The louver sheets are spliced ​​together to form a closed inner barrel side wall structure in a zero deflection state based on the electromagnetic adsorption force.

[0046] S2: Start the water inlet process and perform the washing process or the rinsing process.

[0047] Wash and rinse according to the existing washing method.

[0048] S3: After the washing process or the rinsing process is completed, the washing machine generates a drainage instruction and controls the electromagnetic device to cut off power.

[0049] The louver sheet loses its electromagnetic adsorption force and is in a specified deflection state to form an open inner barrel side wall structure, which can speed up the drainage.

[0050] S4: Execute the drainage process and control the electromagnetic device to be energized after the drainage is completed.

[0051] The louver pieces are spliced ​​again to form a closed inner barrel side wall structure.

[0052] S5: Execute the dehydration process.

[0053] Dehydration is carried out in the existing manner, and each louver sheet can be designed according to the structural design of the existing openings on the side wall of the inner barrel to ensure the implementation of the dehydration process.

[0054] S6: After the last dehydration process is completed, the electromagnetic device is controlled to be powered off.

[0055] After washing is finished, the electromagnetic device is powered off, so that the shutter sheet loses its electromagnetic adsorption force and is in a specified deflection state to form an open inner barrel side wall structure, that is, the inner barrel is kept open when the washing machine is not working. The open inner barrel side wall structure can increase the ventilation area between the inner and outer barrels when not washing, and can quickly evaporate the water remaining between the inner and outer barrels, avoiding the generation of odor and mold between the inner and outer barrels.

[0056] In some embodiments of the present invention, after starting the washing machine, the working type of the washing machine is determined. When the washing program is executed, steps S1 to S6 are executed. When the washing machine executes the barrel self-cleaning program, the louver sheet can be controlled to be in a specified deflection state, so that the water flow stirred by the impeller can not only flush the louver sheet, but also flush the inner wall of the outer barrel, so that the dirt between the inner and outer barrels can be cleaned more thoroughly, thereby achieving a better barrel self-cleaning effect. When the washing machine needs to be repaired, the louver sheet can be controlled to be in a specified deflection state, making the repair more convenient.

[0057] Of course, the present invention is not limited to controlling the electromagnetic device to be energized after receiving a washing instruction. In order to avoid the situation where the user puts in the laundry first and then starts the washing program, which causes the laundry to be sandwiched between the louver pieces, a start instruction may be generated after the user turns on the power of the washing machine, and the start instruction instructs the electromagnetic device to be energized; or a closing instruction may be generated when the user triggers a dedicated inner drum closing button of the washing machine, and the closing instruction instructs the electromagnetic device to be energized, so that the user can put the laundry into the inner drum of the closed inner drum side wall structure.

[0058] It should be noted that, in the specific implementation process, the above-mentioned control part can be implemented by a hardware processor executing computer execution instructions in software form stored in the memory, which will not be elaborated here, and the programs corresponding to the actions performed by the above-mentioned control circuit can be stored in the computer-readable storage medium of the system in software form, so that the processor can call and execute the operations corresponding to the above-mentioned modules.

[0059] The computer-readable storage medium mentioned above may include volatile memory, such as random access memory; may also include non-volatile memory, such as read-only memory, flash memory, hard disk or solid-state drive; may also include a combination of the above types of memory.

[0060] The processor mentioned above may also be a general term for multiple processing elements. For example, the processor may be a central processing unit, or other general-purpose processors, digital signal processors, application-specific integrated circuits, field programmable gate arrays or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor or any conventional processor, etc., or may be a dedicated processor.

[0061] It should be pointed out that the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
