Detailed implementation manners

[0054] In order to more clearly understand the above objects, features and advantages of the embodiments of the present invention, the solutions of the embodiments of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0055] In the following description, many specific details are set forth in order to fully understand the embodiments of the present invention, but the embodiments of the present invention can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0056] Referring to Figures 1 to 17 As shown, this embodiment provides a laundry treatment device. The laundry treatment device includes an outer tub 1 and an inner tub 2 disposed inside the outer tub 1, and there is a water storage gap 10 between the inner tub 2 and the outer tub 1.

[0057] The laundry treatment device can be, for example, a washing machine, a washer-dryer or a garment care machine, etc. Among them, when the laundry treatment device is a washing machine, for example, the washing machine can be a pulsator washing machine. Exemplarily, the laundry treatment device further includes a drive structure 8, the drive structure 8 is connected to the inner tub 2 and is used to drive the inner tub 2 to rotate so as to treat the laundry.

[0058] Among them, a first drain port 223 and a water return port 224 are formed on the inner tub 2, and both the first drain port 223 and the water return port 224 are respectively communicated with the inner cavity of the inner tub 2 and the water storage gap 10.

[0059] A first adjusting member 3 is disposed at the first drain port 223, and the first adjusting member 3 is used to open or close the first drain port 223, and in the open state of the first drain port 223, the water in the inner tub 2 enters the water storage gap 10.

[0060] That is to say, the first adjusting member 3 can open or close the first drain port 223. When the first drain port 223 is open, the water in the inner tub 2 enters the water receiving gap 10 through the first drain port 223. When the first drain port 223 is closed, it can, to a certain extent, prevent the water in the water receiving gap 10 from flowing back into the inner tub 2 through the first drain port 223. Among them, the water in the water receiving gap 10 can circulate back to the inner tub 2 through the water return port 224, so that the water in the inner tub 2 can flow back to the inner tub 2 through the first drain port 223, the water receiving gap 10, and the water return port 224 for recycling.

[0061] Among them, a filter member 5 can also be provided so that the water is filtered by the filter member 5 and then returns to the inner tub 2 through the water return port 224. Specifically, the filter member 5 can be provided at the water return port 224, or can be provided outside the water return port 224, or the filter member 5 can be provided both at the water return port 224 and outside the water return port 224. In addition, the filter member 5 and the water return port 224 can be integrally formed, that is, the water return port 224 itself is formed into a small hole shape and has a filtering function.

[0062] The laundry treatment device provided in this embodiment has a first drain opening 223 and a water return opening 224 formed on the inner drum 2, such that both the first drain opening 223 and the water return opening 224 are respectively in communication with the inner cavity of the inner drum 2 and the water storage gap 10. A first adjusting member 3 is provided at the first drain opening 223, and the first adjusting member 3 is used to open or close the first drain opening 223. When the first drain opening 223 is in the open state, the water in the inner drum 2 enters the water storage gap 10. Meanwhile, a filter member 5 is provided at and / or outside the water return opening 224. With such a setting, the lint generated in the inner drum 2 is discharged out of the inner drum 2 along with the water in the inner drum 2 through the first drain opening 223. Before at least part of the water that enters the water storage gap 10 from the first drain opening 223 flows back into the inner drum 2 through the water return opening 224, it will first pass through the filter member 5 for filtration. Thus, lint and other impurities in the water can be intercepted in the water storage gap 10 to a certain extent, that is, intercepted outside the inner drum 2, realizing self-filtration of lint and other impurities during water return. To a certain extent, it avoids the situation where lint and other impurities enter the inner drum 2 again through the water return opening 224, thereby improving the cleanliness of the water flowing back into the inner drum 2 to a certain extent, avoiding secondary contamination of clothes and the like to a certain extent, eliminating potential safety hazards for users, and being conducive to ensuring the cleaning effect of the clothes in the inner drum 2 and guaranteeing washing health. At the same time, with such a setting, when the water in the laundry treatment device is discharged to the outside of the laundry treatment device, the lint and other impurities intercepted in the water storage gap 10 can be discharged to the outside of the laundry treatment device together with the water in the water storage gap 10, such as directly discharged into the sewer, thus realizing the function of automatic discharge of lint and other impurities, achieving the self-cleaning effect of lint, and avoiding the need for manual operation during the lint cleaning process to a certain extent, thereby improving the user experience.

[0063] In some embodiments, a second adjusting member 4 is provided at the water return opening 224. The second adjusting member 4 is used to open or close the water return opening 224, and when the water return opening 224 is in the open state, the water in the water storage gap 10 enters the inner drum 2.

[0064] That is to say, the second adjusting member 4 can open or close the water return opening 224. When the water return opening 224 is open, the water in the water storage gap 10 circulates back into the inner drum 2 through the water return opening 224; when the water return opening 224 is closed, it can avoid to a certain extent the situation where the water in the inner drum 2 enters the water storage gap 10 through the water return opening 224. That is, through the first adjusting member 3 and the second adjusting member 4, the flow direction of the water can be limited, so that the water in the inner drum 2 can flow through the first drain opening 223, the water storage gap 10, the water return opening 224 and then flow back into the inner drum 2 for recycling. Among them, before the water flows back into the inner drum 2, it will pass through the filter member 5 for filtration.

[0065] Exemplarily, Figure 3The dashed arrow in [the figure] indicates the flow path of the water in the inner tub 2 entering the water storage gap 10 through the first drain opening 223 when the first drain opening 223 is opened. Figure 5 The dashed arrow in [the figure] indicates the flow path of the water in the water storage gap 10 flowing back into the inner tub 2 through the return water opening 224 after being filtered by the filter element 5 via the first drain opening 223 when the return water opening 224 is opened.

[0066] Exemplarily, for example, when the laundry treatment device is a washing machine, during the washing process of the washing machine, the inner tub 2 rotates to drive the clothes and water to agitate under the action of centrifugal force, so that the water in the inner tub 2 passes through the first drain opening 223, the water storage gap 10, the return water opening 224 and then flows back into the inner tub 2, and impurities such as lint are intercepted in the water storage gap 10, realizing self-filtration of impurities such as lint.

[0067] During the dehydration process of the washing machine, the inner tub 2 rotates. At this time, the water in the water storage gap 10 and the inner tub 2 will agitate under the action of centrifugal force, and scour impurities such as lint adhering to or remaining on the filter element 5, the outer side of the inner tub 2, etc., so that the impurities such as lint are peeled off from the filter element 5 and the outer side of the inner tub 2, to a certain extent avoiding the situation of blockage of structures such as the filter element 5, ensuring the filtering effect of the filter element 5 on the water flowing back into the inner tub 2, and further improving the cleanliness of the water in the inner tub 2. The impurities such as lint intercepted in the water storage gap 10 are finally discharged to the outside of the laundry treatment device (such as a sewer) along with the water in the water storage gap 10, thus realizing self-cleaning of impurities such as lint to a certain extent, and to a certain extent avoiding the situation that manual operation is required during the lint cleaning process, saving labor and providing a good user experience.

[0068] In some embodiments, referring to Figure 4 、 Figure 5 、 Figures 14 to 17 As shown, the filter element 5 is located on the side of the second adjusting member 4 facing away from the inner cavity of the inner tub 2.

[0069] This setting can, to a certain extent, avoid the accumulation of impurities such as lint on the inner surface of the side of the filter element 5 facing the inner cavity of the inner tub 2, further avoid the water flowing back into the inner tub 2 being mixed with impurities such as lint, and further ensure the cleanliness of the returned water.

[0070] In some embodiments, the filter element 5 is a filter net. With this setting, the structure of the filter element 5 is simple, convenient to set, and has a good filtering effect on the water in the water storage gap 10. Among them, the pore diameter of the filter net can be set according to actual needs.

[0071] In some embodiments, the filter element 5 is detachably connected to the position of the inner tub 2 corresponding to the return water opening 224.

[0072] With such a setting, when installing or repairing the laundry treatment device, if one of the filter element 5 and the inner cylinder 2 is damaged or broken, only the damaged part needs to be replaced, avoiding the scrapping of the whole of the filter element 5 and the inner cylinder 2, and saving the manufacturing or repair cost.

[0073] Among them, the filter element 5 can be detachably connected to the inner cylinder 2 by means of snap connection or screw connection, etc.

[0074] In some embodiments, the filter element 5 and the inner cylinder 2 are integrally formed. With such a setting, the overall structural strength between the filter element 5 and the inner cylinder 2 is high, which can ensure the good filtering effect of the filter element 5 to a certain extent and is convenient for subsequent assembly.

[0075] Of course, in some other embodiments, the filter element 5 can also be made of sponge or the like.

[0076] In some embodiments, referring to Figures 2 to 13 As shown, the inner cylinder 2 includes a cylinder body 21 and a cylinder bottom 22 connected to the lower end of the cylinder body 21. Among them, the cylinder bottom 22 includes a bottom wall 221 and a side wall 222 extending from the circumferential direction of the bottom wall 221 towards the cylinder body 21.

[0077] Among them, the first drain port 223 can be provided on the side wall of the cylinder body 21, or on the side wall 222 of the cylinder bottom 22, or the first drain port 223 is provided on the side wall of the cylinder body 21 and the side wall 222 of the cylinder bottom 22. With such a setting, water can be discharged more smoothly from the first drain port 223 under the action of centrifugal force.

[0078] In some embodiments, one end of the first adjusting member 3 is rotatably connected to the side wall of the cylinder body 21 and / or the side wall 222 of the cylinder bottom 22, and the other end of the first adjusting member 3 is a free end, so that the first adjusting member 3 rotates towards the direction away from the inner cavity of the inner cylinder 2 under the impact force of the water in the inner cylinder 2 to open the first drain port 223.

[0079] With such a setting, the first adjusting member 3 opens outwards relative to the first drain port 223, which is convenient to open, ensures the smoothness of drainage, and the structure of the first adjusting member 3 is simple.

[0080] Exemplarily, the first rotating shaft for the first adjusting member 3 to be rotatably connected to the side wall of the cylinder body 21 and / or the side wall 222 of the cylinder bottom 22 can be a horizontal rotating shaft, and the top end of the first adjusting member 3 is rotatably connected to the inner cylinder 2, so that the closing effect of the first adjusting member 3 on the first drain port 223 can be improved under the action of the gravity of the first adjusting member 3.

[0081] Of course, the above first rotating shaft can be a vertical rotating shaft, for example, the side of the first adjusting member 3 can be rotatably connected to the inner cylinder 2.

[0082] Of course, in some other embodiments, the first adjusting member 3 may also be a one-way valve.

[0083] In some embodiments, referring to Figures 2 to 13 As shown, a first blocking member 6 is further provided at the first drain port 223. The first blocking member 6 is located on the side of the first adjusting member 3 facing the inner cavity of the inner cylinder 2 to prevent the first adjusting member 3 from rotating in the direction from the first drain port 223 towards the inner cavity of the inner cylinder 2.

[0084] With this setting, the first blocking member 6 can block the first adjusting member 3 during backwater, preventing the first adjusting member 3 from rotating in the reverse direction, and avoiding the water in the water storage gap 10 from entering the inner cylinder through the first drain port 223, so that as much water as possible in the water storage gap 10 flows back to the inner cylinder 2 through the water return port 224, which is beneficial to ensuring the cleanliness of the water flowing back to the inner cylinder 2.

[0085] In some embodiments, referring to Figure 6 and Figure 7 As shown, the first blocking member 6 is a first blocking rib provided at the first drain port 223. With this setting, the structure is simple and the design is convenient.

[0086] In some embodiments, the first blocking rib is integrally formed with the inner cylinder 2. This makes the integrity of the first blocking rib and the inner cylinder 2 good, with high structural strength, ensuring the stable blocking of the first adjusting member 3 by the first blocking rib and facilitating subsequent assembly.

[0087] In some embodiments, referring to Figure 6 and Figure 7 As shown, the first blocking rib extends along the circumferential direction of the inner cylinder 2. With this setting, the blocking effect is further improved.

[0088] In some embodiments, there are at least two first blocking ribs, and at least two first blocking ribs are arranged at intervals along the axial direction of the inner cylinder 2.

[0089] With this setting, the first adjusting member 3 can be well blocked at multiple positions in the axial direction of the inner cylinder 2, further avoiding the situation where the first adjusting member 3 opens the first drain port 223 during backwater, and ensuring the cleanliness of the water flowing back to the inner cylinder 2.

[0090] Of course, in some other embodiments, the first blocking member 6 may also be a blocking block or the like.

[0091] In some embodiments, the first adjusting member 3 may be a flexible sheet, such as a rubber sheet or a silicone sheet. With this arrangement, the first adjusting member 3 has good flexibility and smoothness when rotating to open and close the first drain port 223, and is convenient to use, thereby facilitating the improvement of the self-filtration efficiency and self-cleaning efficiency of impurities such as hair scraps. Moreover, this can also prevent the first adjusting member 3 from being damaged by wear to a certain extent, protect the first adjusting member 3, and prolong the service life of the first adjusting member 3.

[0092] Of course, in other embodiments, the first adjusting member 3 may also be a hard sheet such as a metal sheet.

[0093] In some embodiments, reference Figures 4 to 17 As shown, one end of the second adjusting member 4 is rotatably connected to the inner tube 2, and the other end of the second adjusting member 4 is a free end, so that the second adjusting member 4 rotates toward the inner cavity of the inner tube 2 under the impact force of water in the water-containing gap 10 to open the water return port 224.

[0094] This arrangement allows the second adjusting member 4 to open inwardly relative to the water return port 224 , making it easy to open and ensuring smooth water return. Meanwhile, the second adjusting member 4 has a simple structure.

[0095] Exemplarily, the second rotating shaft that rotationally connects the second adjusting member 4 and the side wall of the inner tube 2 can be, for example, a horizontal rotating shaft, and the top end of the second adjusting member 4 is rotationally connected to the inner tube 2, so that the closing effect of the second adjusting member 4 on the return water port 224 can be improved under the action of gravity of the second adjusting member 4.

[0096] Of course, the second rotating shaft may be a vertical rotating shaft, for example, the side edge of the second adjusting member 4 may be rotatably connected to the inner cylinder 2 .

[0097] Of course, in other embodiments, the second adjusting member 4 may also be a one-way valve.

[0098] In some embodiments, reference Figures 4 to 17 As shown, the water return port 224 can be specifically arranged on the side wall of the cylinder body 21, or on the side wall 222 of the cylinder bottom 22, or on the side wall 222 of the cylinder body 21 and the side wall 222 of the cylinder bottom 22. Such an arrangement can improve the water return efficiency.

[0099] Of course, in other embodiments, the water return port 224 may also be disposed on the bottom wall 221 of the inner tube 2 .

[0100] In some embodiments, reference Figures 4 to 17 As shown, a second blocking member 7 is also provided at the water return port 224. The second blocking member 7 is located on the side of the second adjusting member 4 away from the inner cavity of the inner cylinder 2 to prevent the second adjusting member 4 from rotating from the water return port 224 toward the water containing gap 10.

[0101] In this arrangement, the second blocking member 7 can block the second adjusting member 4 when the water in the inner cylinder 2 is discharged, preventing the second adjusting member 4 from rotating in the opposite direction, thereby preventing the water in the inner cylinder 2 from entering the water containing gap 10 through the water return port 224 .

[0102] In addition, when the filter element 5 is arranged at the return water port 224 and the filter element 5 is located on the side of the second adjusting member 4 facing away from the inner cavity of the inner cylinder 2, this can prevent impurities such as hair debris in the inner cylinder 2 from being blocked on the side of the filter element 5 facing the inner cavity of the inner cylinder 2, thereby affecting the cleanliness and smoothness of the return water. In addition, the filter element 5 will not interfere with the rotation of the second adjusting member 4 to open the return water port 224. The second adjusting member 4 rotates flexibly, making the setting of the filter element 5 more convenient.

[0103] In some embodiments, reference Figures 4 to 17 As shown, the second blocking member 7 is a second blocking rib arranged at the water return port 224, which has a simple structure and convenient design.

[0104] In some embodiments, the second blocking rib is integrally formed with the inner cylinder 2. This makes the overall structural strength of the second blocking rib and the inner cylinder 2 high, ensures the second blocking rib stably blocks the second adjusting member 4, and facilitates subsequent assembly.

[0105] In some embodiments, reference Figure 6 and Figure 8 As shown, the second blocking rib is arranged to extend along the circumference of the inner cylinder 2, and this arrangement further improves the blocking effect.

[0106] In some embodiments, reference Figure 6 and Figure 8 As shown, there are at least two second blocking ribs, and the at least two second blocking ribs are arranged at intervals along the axial direction of the inner tube 2.

[0107] This arrangement can well block the second adjusting member 4 from multiple positions in the axial direction of the inner tube 2, further avoiding the situation where the second adjusting member 4 opens the return water port 224 when the water in the inner tube 2 is discharged, thereby ensuring the cleanliness of the water flowing back into the inner tube 2.

[0108] Of course, in other embodiments, the second blocking member 7 may also be a blocking block or the like.

[0109] In some embodiments, the second adjusting member 4 may be a flexible sheet, such as a rubber sheet or a silicone sheet specifically. With such a setting, when the second adjusting member 4 rotates to open and close the water return port 224, it has good flexibility and high smoothness, which is convenient to use, thereby facilitating the improvement of the self-filtering efficiency and self-cleaning efficiency of lint. Moreover, this can also avoid the situation where the second adjusting member 4 is worn and damaged to a certain extent, protect the second adjusting member 4, and enable the second adjusting member 4 to have a relatively long service life.

[0110] Of course, in some other embodiments, the second adjusting member 4 may also be a rigid sheet such as a metal sheet.

[0111] In some embodiments, referring to Figures 6 to 9 as shown, the first drain port 223 and the water return port 224 may be opened on one side of the side wall 222 of the barrel bottom 22 close to the bottom wall 221 of the barrel bottom 22. Referring to Figure 9 as shown, it can be understood that: in the height direction of the barrel bottom 22, that is, Figure 9 in the direction indicated by the arrow M, the first drain port 223 and the water return port 224 are specifically opened below the 1 / 2 height of the side wall 222 of the barrel bottom 22.

[0112] Since the barrel bottom 22 is basically the position that first contacts water and finally discharges water during clothing treatment, through the above settings, the clothing treatment device will not affect the self-filtering and self-cleaning functions of lint due to different amounts of water in the inner barrel 2, and can ensure that impurities such as lint in the inner barrel 2 are completely discharged without residue as much as possible.

[0113] In some embodiments, referring to Figures 2 to 17 as shown, in the direction from the middle of the bottom wall 221 of the barrel bottom 22 to the edge of the bottom wall 221 of the barrel bottom 22, the bottom wall 221 of the barrel bottom 22 extends downward and obliquely. Among them, the direction from the middle of the bottom wall 221 to the edge of the bottom wall 221 specifically refers to Figure 3 , Figure 10 , Figure 12 , Figure 15 and Figure 16 the one-way arrow S direction shown.

[0114] With such a setting, it is beneficial to improve the efficiency of the water in the inner cavity of the inner barrel 2 being discharged from the first drain port 223, thereby further improving the self-filtering effect and self-cleaning effect of impurities such as lint.

[0115] In some embodiments, referring to Figure 6 as shown, the first drain port 223 has at least two, and at least two first drain ports 223 are arranged at intervals along the circumferential direction of the inner barrel 2. With such a setting, the drainage efficiency can be improved, and thus the clothing treatment efficiency can be improved.

[0116] In some embodiments, there are at least two water return ports 224, which are arranged at intervals along the circumference of the inner drum 2. This arrangement can improve the water return efficiency and thus improve the laundry processing efficiency. In this case, a filter 5 is provided at each water return port 224, thereby further improving the filtering effect.

[0117] Continue to refer to Figure 6 As shown, all first drainage ports 223 and all return water ports 224 can be arranged alternately and spaced in sequence along the circumference of the inner tube 2. This can further improve the return water efficiency and drainage efficiency.

[0118] In some embodiments, reference Figure 9 As shown, a second drain port 225 is further provided on the cylinder bottom 22 . The opening area of ​​the second drain port 225 is smaller than that of the first drain port 223 , so that the drainage volume of the second drain port 225 is smaller than that of the first drain port 223 .

[0119] In this way, the residual water in the inner drum 2 is discharged through the second drain port 225, which to a certain extent avoids the residual water in the inner drum 2 for a long time without being cleaned in time and causing odor or breeding of bacteria, thereby ensuring the cleanliness of the inner drum 2, achieving good clothing cleaning effect and healthy washing.

[0120] Exemplarily, the inner drum 2 also includes a pulsator 23 rotatably connected to the drum bottom 22, the above-mentioned driving structure 8 is located on the outer side of the drum bottom 22 in the axial direction, and part of the driving structure 8 can be extended from the bottom wall 221 of the drum bottom 22 into the inner cavity of the inner drum 2, the driving structure 8 and the pulsator 23 are connected by a washing shaft, the driving structure 8 and the drum bottom 22 are connected by a dehydration shaft, and the driving structure 8 can drive the washing shaft to rotate, so as to drive the inner drum 2 to rotate, so as to achieve the cleaning of the clothes, and can drive the dehydration shaft or drive the dehydration shaft and the washing shaft to rotate at the same time, so as to drive the inner drum 2 to rotate, so as to achieve the dehydration of the clothes. Exemplarily, for example, a mounting hole 2212 is opened on the bottom wall 221 of the drum bottom 22, and for example, the drum bottom 22 is fixed to the dehydration shaft by a screw passing through the mounting hole 2212.

[0121] In some embodiments, reference Figure 9 As shown, a concave cavity 2211 is provided on the cylinder bottom 22, which is concave in a direction away from the inner cavity of the inner cylinder 2. A rotating shaft for driving the inner cylinder 2 to rotate is located in the concave cavity 2211. The second drain port 225 is provided in the concave cavity 2211 and is staggered with the rotating shaft. The concave cavity 2211 can be specifically provided in the middle of the cylinder bottom 22.

[0122] The rotating shaft here may specifically include the above-mentioned washing shaft and a dehydrating shaft sleeved outside the washing shaft. Due to the arrangement of the concave cavity 2211, residual water is likely to exist in the inner cavity of the inner cylinder 2. Therefore, by providing a second drain port 225 in the concave cavity 2211, the water remaining in the concave cavity 2211 can be drained, ensuring the cleanliness of the inner cylinder 2.

[0123] In some embodiments, when the first drain port 223 and the water return port 224 are specifically arranged at the bottom 22 of the cylinder, there are no holes in the cylinder body 21 at this time, or holes are only provided in the part of the cylinder body 21 above the highest washing water level.
