DETAILED DESCRIPTION

[0033] As described in the background art, when washing machines of related art are used, different types of clothes are placed in the inner drum for mixed washing, which poses a risk of cross-contamination and is detrimental to the health of users. For example, when underwear and outerwear are washed together, germs may stick to the underwear, and users may get germs on their private parts after putting on the underwear.

[0034] In the solutions of the related art, if you want to wash underwear and outerwear separately, you usually need to purchase a washing machine specifically for washing underwear, which not only takes up space but also increases the cost invested by the user.

[0035] In view of this, the embodiment of the present application aims to provide a washing machine, by arranging multiple washing drums in the inner drum, the multiple washing drums divide the inner drum into multiple independent washing spaces, and when the inner drum rotates, the washing drum also rotates, thereby realizing the function of washing different clothes in different zones. The embodiment of the present application forms multiple independent washing spaces in the inner drum through the modification of the inner drum to meet the demand of zoned washing without the need to purchase a separate washing machine.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] Figure 1 is a simplified structural diagram of a washing machine provided in one embodiment of the present application; Figure 2 is a simplified structural diagram of a washing drum provided in one embodiment of the present application; Figure 3 is a partial view of the outer side of the circumferential side wall provided by an embodiment of the present application; Figure 4 It is a partial cross-sectional view of a circumferential side wall provided in one embodiment of the present application.

[0038] Please refer to Figure 1-Figure 4 The present embodiment provides a washing machine, including a housing 100, in which an outer drum 110 and an inner drum 120 are arranged. The outer drum 110 can be installed in the housing 100 through a suspension spring 130 and a damper 140, and the inner drum 120 is rotatably arranged in the outer drum 110. For example, a motor 111 is also arranged in the housing 100, and the motor 111 is installed on the outer drum 110. The rotating shaft of the motor 111 passes through the outer drum 110 and is connected to the inner drum 120 to drive the inner drum 120 to rotate. A water inlet pipe 150 connected to the outer drum 110 is also arranged in the housing 100, and the water inlet pipe 150 can introduce water into the outer drum 110 to soak and wash clothes. A machine door 170 is also arranged on the housing 100, and the machine door 170 can be hinged with the housing 100, so as to facilitate the user's door opening operation to put in or take out clothes. A sealing gasket 171 may be provided between the door 170 and the housing 100 to achieve sealing.

[0039] In this embodiment, a plurality of washing drums 200 are provided in the inner drum 120, and the plurality of washing drums 200 are arranged at intervals along the axial direction of the inner drum 120, and the plurality of washing drums 200 can rotate with the inner drum 120. A washing space is formed in the washing drum 200, and when the washing drum 200 rotates with the inner drum 120, the clothes in the washing drum 200 will be washed. In this embodiment, the specific number of the washing drums 200 in the inner drum 120 can be set as needed, and this embodiment does not limit this.

[0040] Through the above arrangement, in this embodiment, the inner drum 120 can be divided into a plurality of independent washing spaces by using a plurality of washing drums 200. When the inner drum 120 rotates, the washing drum 200 also rotates accordingly, thereby realizing the function of washing different clothes in different zones.

[0041] Specifically, the washing drum 200 of this embodiment includes an axial side wall 201 perpendicular to the axial direction of the inner drum 120 and a circular circumferential side wall 202 coaxially arranged with the inner drum 120, wherein the axial side wall 201 is provided with a clothes-dropping hole 2011, through which the user can put clothes into the washing drum 200.

[0042] Furthermore, the multiple washing drums 200 include several intermediate drums 210 and one terminal drum 220, wherein the two opposite axial side walls 201 of the intermediate drum 210 are each provided with a clothes throwing hole 2011, and the axial side wall 201 of the terminal drum 220 facing the intermediate drum 210 is provided with a clothes throwing hole 2011; that is, the intermediate drum 210 and the terminal drum 220 in this embodiment are different only in the number of clothes throwing holes 2011 (two corresponding clothes throwing holes 2011 are provided on the intermediate drum 210 to facilitate the passage of the stepped drum 310), and the rest of the structures are similar.

[0043] In a possible embodiment, the inner drum 120 is further provided with a partitioned liquid delivery device, which includes a stepped drum 310, which is connected to the water inlet pipe 150 of the washing machine to receive washing water. The stepped drum 310 is also connected to multiple washing drums 200 to deliver liquid into the washing drums 200.

[0044] Exemplarily, the step cylinder 310 is arranged in the clothes throwing hole 2011 of the middle cylinder 210 and the clothes throwing hole 2011 of the end cylinder 220. Accordingly, the step cylinder 310 is provided with a plurality of openings 311, which correspond to the plurality of middle cylinders 210 one by one, and the step cylinder 310 is also provided with a terminal opening 312 connected to the clothes throwing hole 2011 of the end cylinder 220, and the detergent and washing water can enter the corresponding washing cylinder 200 through the opening 311 or the terminal opening 312.

[0045] In one possible implementation, Figure 1 Taking the example shown, this embodiment includes three washing drums 200 (one end drum 220 and two middle drums 210). When in use, small and relatively long clothes such as bras, scarves, and neck scarves can be placed in the end drum 220; larger clothes such as underwear can be placed in the middle drum 210 in the middle; shorter clothes such as socks can be placed in the outermost middle drum 210; and the zoned liquid feeding device is inserted into the clothes feeding hole 2011 of each washing drum 200 and placed according to the position shown in the figure; finally, the washing machine is started to achieve zoned washing of different clothes.

[0046] In one possible implementation, the diameters of the clothes-dropping holes 2011 on the multiple washing drums 200 in this embodiment are different from each other. From the end drum 220 to the middle drum 210, the diameters of the clothes-dropping holes 2011 on different washing drums 200 gradually increase, and the diameters of the clothes-dropping holes 2011 on the same washing drum 200 are equal.

[0047] In order to achieve coordination with multiple washing drums 200, the stepped drum 310 includes several middle sections and a final section. The diameters of the middle sections are different from the diameters of the final sections. The middle sections are matched one by one with the clothes-feeding holes 2011 on the middle drums 210, and the final section is matched with the clothes-feeding holes 2011 on the final drum 220.

[0048] Furthermore, the stepped cylinder 310 of the present embodiment is clearance-matched with the clothes-dropping hole 2011, which can facilitate installation and disassembly between the stepped cylinder 310 and the washing cylinder 200, and can also prevent the stepped cylinder 310 from being squeezed when the washing cylinder 200 is eccentric.

[0049] In order to achieve the sealing of the washing drum 200 and prevent the exchange of washing water in different washing drums 200 during the washing process, in this embodiment, the middle section adjacent to the end section of the step drum 310 abuts on the terminal drum 220; that is, the step surface formed by the end section of the step drum 310 and the adjacent middle section abuts on the axial side wall 201 of the terminal drum 220, so that the step surface is used to achieve the sealing of the terminal drum 220, ensuring that the water in the two adjacent washing drums 200 cannot enter each other.

[0050] Similarly, another middle section adjacent to the middle section of the stepped cylinder 310 and having a larger diameter than the middle section abuts against the intermediate cylinder 210 matched with the middle section; that is, the step surface formed by the middle section and the middle section adjacent to the middle section having a larger diameter abuts against the axial side wall 201 of the intermediate cylinder 210 corresponding to the middle section, thereby achieving sealing of the intermediate cylinder 210 by using the step surface. Figure 1 For example, Figure 1 The middle ladder tube 310 includes two middle sections, and the two middle sections are respectively inserted into the two middle tubes 210. Figure 1 The diameter of the middle section of the middle tube 210 in the middle part is smaller than the diameter of the Figure 1 The diameter of the middle section in the middle cylinder 210 on the right side of the middle. A step surface is formed between the middle section in the middle and the middle section on the right side, and the step surface abuts against the axial side wall 201 of the middle cylinder 210 in the middle, so that the middle cylinder 210 in the middle is sealed by the step surface, ensuring that the water in the two adjacent washing cylinders 200 cannot enter each other.

[0051] Since adjacent washing drums 200 are spaced apart, even if a small amount of water passes through the gap between the clothes-dropping hole 2011 and the stepped drum 310 , the washing water will flow into the inner drum 120 along the axial side wall 201 , and the washing water will not be exchanged in different washing drums 200 .

[0052] In a possible implementation, the partitioned liquid delivery device and the multiple washing drums 200 of this embodiment can be detachably arranged in the inner drum 120, and can be completely removed when not in use, so that the inner drum 120 can restore the original washing space.

[0053] In a possible implementation, the inner drum 120 of this embodiment is provided with a plurality of lifting ribs 121, and a plurality of grooves 203 are provided on the circumferential side wall 202 of the washing drum 200, and the plurality of grooves 203 correspond to the plurality of lifting ribs 121 one by one, and the washing drum 200 is fixed on the plurality of lifting ribs 121 by the plurality of grooves 203, thereby realizing a detachable connection between the washing drum 200 and the inner drum 120. Preferably, the depth of the grooves 203 may be slightly less than the height of the lifting ribs 121, so that there is a very small gap between the washing drum 200 and the inner drum 120, which minimizes the impact on the falling force while also taking into account the subsequent drainage of the washing drum 200.

[0054] Furthermore, a plurality of internal lifting ribs 204 are provided in the washing tub 200 of the present embodiment. The plurality of internal lifting ribs 204 correspond one-to-one to the plurality of grooves 203 . The washing efficiency of the washing tub 200 can be improved by providing the internal lifting ribs 204 .

[0055] In one possible embodiment, in order to enable the washing tub 200 to store a small amount of water during washing and discharge the internal washing water during dehydration, a plurality of semi-permeable holes 2021 are provided on the circumferential side wall 202 of the washing tub 200. The semi-permeable holes 2021 include a plurality of hole petals 2022, and the hole petals 2022 are elastic hole petals, such as silicone hole petals, rubber hole petals, etc.; a gap 2023 is formed between two adjacent hole petals 2022. When the rotation speed of the washing tub 200 is less than a preset value, the gap 2023 can be sealed by the elastic force between the two adjacent hole petals 2022, and at this time, the two adjacent hole petals 2022 are closely abutted, so that the gap 2023 is impermeable. When the rotation speed of the washing tub 200 is greater than the preset value, the hole petals 2022 flip toward the side away from the inside of the washing tub 200 to expand the gap 2023, so that the washing water in the washing tub 200 is discharged. It can be understood that the larger the aperture petals 2022 are, the easier it is for the gaps between the aperture petals 2022 to become larger under the action of centrifugal force, so the size of the aperture petals 2022 is set according to the size of a preset value, and the preset value is set according to the washing requirements of washing and rinsing, for example, it can be 40-60 rpm.

[0056] Furthermore, a plurality of pits 205 are provided on the circumferential side wall 202, and semi-permeable holes 2021 are provided in the pits 205, and the plurality of semi-permeable holes 2021 correspond one to one with the plurality of pits 205. The provision of the pits 205 is not only convenient for drainage, but also ensures that even if the washing tub 200 is in close contact with the inner tub 120, the drainage of the washing tub 200 will not be affected.

[0057] Preferably, the washing drum 200 of this embodiment is a flexible drum, for example, a silicone drum or a rubber drum, etc. Setting the washing drum 200 as a flexible drum can facilitate the user to put the clothes into the washing drum 200 first, and then put the washing drum 200 into the inner drum 120; at the same time, the flexible drum also facilitates the washing drum 200 to be turned outward and aired after use to keep it dry and avoid the breeding of bacteria.

[0058] Furthermore, the thickness of the circumferential side wall 202 of the washing drum 200 of this embodiment is greater than the thickness of the axial side wall 201. In this way, the hardness of the circumferential side wall 202 can be appropriately improved, which is convenient for increasing the effect of clothes being beaten and improving the washing efficiency of clothes. The softer axial side wall 201 facilitates the washing drum 200 to be turned outward, which is convenient for the user to remove the washing drum 200 from the inner drum 120 and then dry it; at the same time, it is also beneficial to reduce the disturbance to the stepped drum 310 when the washing drum 200 vibrates due to eccentric operation during use.

[0059] In one possible embodiment, in order to introduce detergent and washing water into different washing drums 200 respectively, a plurality of main water pipes 160 are provided in the washing machine of this embodiment, and the plurality of main water pipes 160 are all connected to the water inlet pipe 150; a distributor 151 can be provided between the water inlet pipe 150 and the plurality of main water pipes 160, so as to achieve the distribution of detergent and washing water. The partitioned liquid delivery device also includes a plurality of water distribution pipes 320, and the plurality of water distribution pipes 320 are all located in the stepped drum 310, and each water distribution pipe 320 is connected to a washing drum 200 through an opening 311 or an end opening 312, and the plurality of water distribution pipes 320 correspond one to one with the plurality of main water pipes 160, so that detergent and washing water can be introduced into the corresponding washing drum 200. Through the above arrangement, different types and volumes of detergent and / or washing water can be put into different washing drums 200.

[0060] In this embodiment, the diameter of the opening 311 is preferably matched with the diameter of the corresponding water distribution pipe 320, so that the two are kept in a sealed connection to prevent the washing water from being exchanged between different washing drums 200 through the inside of the stepped drum 310. Furthermore, a water retaining plate 313 can be connected to the end opening 312 to prevent the washing water in the end drum 220 from entering the stepped drum 310.

[0061] The multiple main water pipes 160 of this embodiment can be arranged above the corresponding multiple branch water pipes 320 after passing through the sealing gasket 171. In order to facilitate the collection of washing water in the main water pipe 160, a water receiving funnel 330 is also provided on the branch water pipe 320. The water receiving funnel 330 is located at one end of the branch water pipe 320 facing the main water pipe 160.

[0062] Furthermore, the partitioned liquid delivery device further includes an inclined cylinder 340 and a suction cup 350. The inclined cylinder 340 is connected to one end of the stepped cylinder 310 close to the machine door 170. The inclined cylinder 340 abuts against the machine door 170. The opening of the inclined cylinder 340 can be located below the sealing gasket 171. The plurality of water distribution pipes 320 can be located in the inclined cylinder 340. After being installed in place, the upper end of the inclined cylinder 340 is just located in the space between the machine door 170 and the sealing gasket 171. On the one hand, it can be used as a foolproof design. If the user does not install it in this way, the machine door 170 cannot be closed. On the other hand, this can also prevent the inclined cylinder 340 from rotating when the washing drum 200 rotates.

[0063] The suction cup 350 is located on the side of the step cylinder 310 facing the machine door 170. When the machine door 170 is closed, the suction cup 350 is attached to the machine door 170, thereby preventing the step cylinder 310 from rotating with the washing cylinder 200 and avoiding the multiple water distribution pipes 320 fixed inside from being damaged. When the machine door 170 is closed, the squeezing force transmitted to the step cylinder 310 by the suction cup 350 can make the cylinder shoulder on the step cylinder 310 fit more closely to the corresponding washing cylinder 200, preventing the washing water from being exchanged between the washing cylinders 200, so that each washing cylinder 200 forms its own independent washing space.

[0064] When the door 170 is opened, the opening and closing angle of the door 170 is inclined relative to the suction surface of the suction cup 350 , so it is easy for the suction cup 350 to get rid of the door 170 .
