[0050] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0051] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0052] The laundry treatment device 1000 according to the embodiments of the present invention will be described below with reference to the accompanying drawings of the specification.

[0053] As shown Figures 1 - 3 in FIG. Figures 1 - 3 , the laundry treating apparatus 1000 according to an embodiment of the present invention includes: an outer tub 100, an inner tub 200, and a water spraying member 300.

[0054] As shown Figure 3 in FIG. Figure 3 , the outer tub 100 has a water inlet 110 which is adapted to be connected to an external water source, so as to ensure that the water provided by the external water source can enter the laundry treating apparatus 1000 to wet the laundry placed in the laundry treating apparatus 1000, facilitating the cleaning of the laundry in the laundry treating apparatus 1000.

[0055] The inner tub 200 is rotatably disposed in the outer tub 100, and the inner tub 200 defines a laundry treating chamber 211. The inner tub 200 has a water inlet chamber 220 which is in communication with the laundry treating chamber 211.

[0056] The water spraying member 300 is disposed in the outer tub 100, and the water spraying member 300 has a water spraying passage 321 (for the specific structure of the water spraying passage 321, reference can be made to Figure 7 ), and the water spraying passage 321 communicates with the water inlet 110 and the inlet 221 of the water inlet chamber 220, so that the water entering from the water inlet 110 can be sprayed towards the inlet 221 of the water inlet chamber 220.

[0057] When the laundry needs to be cleaned, the laundry to be treated can be placed in the laundry treating chamber 211. As the inner tub 200 rotates, the inner tub 200 can drive the laundry in the laundry treating chamber 211 to rotate together, thereby raising the height of the laundry. The laundry with continuously increasing height will fall back under the action of gravity, thereby realizing the up-and-down beating of the laundry and the flipping of the laundry, achieving the purpose of treating the laundry.

[0058] For the laundry treating apparatus 1000 according to an embodiment of the present invention, by providing the water inlet chamber 220 in communication with the laundry treating chamber 211, when the water spraying member 300 sprays water into the water inlet chamber 200, the water entering the water inlet chamber 220 can enter the laundry treating chamber 211 to wet the laundry in the laundry treating chamber 211, facilitating the subsequent cleaning of the laundry.

[0059] By providing the water spraying member 300 and disposing the water spraying member 300 on the outer tub 100, on the one hand, the water spraying member 300 can be disposed close to the water inlet 110, so that the water at the water inlet 110 can directly flow into the water spraying member 300 without setting other connecting members, reducing the production cost and simplifying the structure of the laundry treating apparatus 1000 at the same time; on the other hand, the outer tub 100 is used to support the water spraying member 300 to improve the position stability of the water spraying member 300, ensuring that the water spraying member 300 can stably spray water towards the inlet 221 of the water inlet chamber 220.

[0060] According to some embodiments of the present invention, the water spraying member 300 further has a water spraying channel 321. The water spraying channel 321 communicates with the water inlet 110 and the inlet 221 of the water inlet chamber 220. It can also be understood that the water spraying channel 321 directly communicates with the water inlet 110 and the laundry treatment chamber 211. In this way, the water entering from the water inlet 110 can directly flow into the laundry treatment chamber 211, avoiding the water flowing through the outer tub 100 first and then flowing into the laundry treatment chamber 211. Through the above arrangement, the flowing path of the water can be shortened, the water inlet efficiency can be improved, and then the wetting efficiency of the laundry can be improved. Moreover, the water entering the laundry treatment chamber 211 can be prevented from being doped with dirt and bacteria in the outer tub 100, so as to ensure that the water entering the laundry treatment chamber 211 is free of dirt and bacteria, guarantee the cleanliness of the laundry treatment chamber 211, so that no bacteria remain on the laundry, ensure the health of the human body, and improve the user experience.

[0061] It can be understood that, compared with the prior art, in the laundry treatment device 1000 of the present application, by providing the water spraying member 300 that sprays the water entering from the water inlet 110 directly toward the inlet 221 of the water inlet chamber 220, the water spraying member 300 not only improves the water inlet efficiency of the laundry treatment device 1000, but also avoids the water entering the inner tub 200 being doped with dirt and bacteria in the outer tub 100, thus guaranteeing the cleanliness of the inner tub 200 and improving the cleaning degree of laundry treatment to enhance the user experience.

[0062] As Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, a water inlet valve 900 is provided above the outer tub 100. The water inlet valve 900 is connected between the water inlet 110 and an external water source, and the flow of water toward the water inlet 110 is controlled by opening or closing the water inlet valve 900. The water inlet valve 900 can be directly installed on the outer tub 100, that is, the outer tub 100 supports the water inlet valve 900 to improve the position stability of the water inlet valve 900. The water inlet valve 900 can also be installed on the cabinet of the laundry treatment device 100.

[0063] In some embodiments, the laundry treatment device 1000 further includes a water inlet pipe 700. One end of the water inlet pipe 700 is connected to the water inlet valve 900, and the other end of the water inlet pipe 700 is connected to the water inlet 110. By providing the water inlet pipe 700, the flow direction of the water flow can be guided to divert the external water source to the water inlet 110, so as to realize water inlet into the inner tub 200.

[0064] Optionally, as Figure 1 and Figure 2As shown, the laundry treatment device 1000 further includes a detergent dispensing component 800. Cleaning media such as detergents, bleaches, and fabric softeners can be placed inside the detergent dispensing component 800. The detergent dispensing component 800 is located above the outer tub 100. Specifically, the detergent dispensing component 800 can be installed on the outer tub 100 or on the casing of the laundry treatment device 1000.

[0065] The detergent dispensing component 800 is located on the water flow path between the water inlet valve 900 and the water inlet 110. In this way, the water flowing from the water inlet valve 900 towards the water inlet 110 can drive the cleaning media (detergent, bleach, fabric softener) to flow into the inner tub 200 together, so as to clean the clothes inside the inner tub 200 and improve the cleanliness of the laundry treatment. Among them, Figure 6 shows the flow direction of the water flowing from the water inlet valve 900 towards the water inlet 110, Figure 6 and the arrow in it is the flow direction of the water.

[0066] In some examples, there are two water inlet pipes 700. One of the water inlet pipes 700 is connected between the water inlet valve 900 and the detergent dispensing component 800 to introduce external water source into the detergent dispensing component 800, so as to wash and dissolve the cleaning media. The other water inlet pipe 700 is connected between the detergent dispensing component 800 and the water inlet 110. The water and cleaning media entering the detergent dispensing component 800 flow through the water inlet pipe 700 to the water inlet 110, and then flow into the inner tub 200 through the water inlet 110 and the water spraying member 300, so as to clean the clothes inside the inner tub 200.

[0067] It should be noted that by setting the water spraying member 300 in the present application, it can be ensured that the cleaning media flowing to the water inlet 110 is directly sprayed into the inlet 221 of the water inlet cavity 220 through the water spraying channel 321, and then enters the inner tub 200. With such a setting, it can be avoided that the cleaning media first flows through the outer tub 100 and then flows into the inner tub 200, thus solving the technical problem that part of the cleaning media will stay between the inner tub 200 and the outer tub 100 and the utilization rate of the cleaning media is relatively low, so as to effectively improve the utilization rate of the cleaning media. While saving the use cost of the cleaning media, the quality of the laundry treatment is also improved.

[0068] It can be seen from this that only by setting one water spraying member 300 in the present application can the water entering from the water inlet 110 be directly led into the inner tub 200, solving the technical problems in the prior art such as low efficiency of wetting clothes, decreased utilization rate of detergents, and the water entering the inner tub 200 being contaminated with dirt and bacteria in the outer tub. Moreover, the cost of the water spraying member 300 is relatively low and it will not occupy too much space of the laundry treatment device 1000.

[0069] In some embodiments of the present invention, such as Figure 3As shown, the water spraying member 300 is disposed inside the bottom wall of the outer tub 100. By the above arrangement, the space outside the outer tub 100 can be avoided from being occupied by the water spraying member 300. While improving the aesthetic appearance of the laundry treatment apparatus 1000, the bottom wall of the outer tub 100 can protect the water spraying member 300 and extend the service life of the water spraying member 300.

[0070] It should be noted that the bottom wall of the outer tub 100 mentioned here refers to the wall of the outer tub 100 that is oppositely arranged with respect to the laundry access opening. The water spraying member 300 is disposed inside the bottom wall of the outer tub 100 and is arranged close to the bottom wall of the outer tub 100, so that the water spraying member 300 can be arranged close to the water inlet 110 and the water inlet chamber 220 at the same time, thereby reducing the volume of the water spraying member 300 and ensuring that the water spraying member 300 can effectively spray the water at the water inlet 110 into the water inlet chamber 220.

[0071] Optionally, as Figure 4 shown, a water passing channel 400 is defined between the water spraying member 300 and the inner side of the bottom wall of the outer tub 100. The water passing channel 400 communicates the water inlet 110 and the water spraying channel 321. The water passing channel 400 can guide the flow of water, ensure that the water can flow along a predetermined route, so as to ensure that the water entering from the water inlet 110 can smoothly flow into the water spraying channel 321 through the water passing channel 400, and then flow into the inlet 221 of the water inlet chamber 220 through the water spraying channel 321.

[0072] It can be seen from this that in the laundry treatment apparatus 1000 of the present application, the flow path of water is as follows: the external water source enters the water inlet 110 through the water inlet pipe 700, and the water entering from the water inlet 110 is sprayed toward the inlet 221 of the water inlet chamber 220 through the water passing channel 400 and the water spraying channel 321 in sequence, so as to ensure that the water can accurately enter the water inlet chamber 220. Since the water inlet chamber 220 is communicated with the laundry treatment chamber 211, the water entering the water inlet chamber 220 can enter the laundry treatment chamber 211 and wet the clothes in the laundry treatment chamber 211, thereby facilitating the treatment of the clothes in the laundry treatment chamber 211.

[0073] Optionally, as Figure 3 and Figure 4 shown, the water inlet 110 is located at the bottom wall of the outer tub 100, and the water spraying member 300 covers the water inlet 110. Ensure that the water entering from the water inlet 110 can directly and completely enter the water passing channel 400, shorten the flow path of the water flow and reduce the risk of water leakage, improve the water inlet efficiency while avoiding waste of water resources, and can improve the utilization rate of water, thereby enhancing the wetting efficiency of the clothes.

[0074] In some embodiments, one of the water spraying member 300 and the outer tub 100 has an annular rib 120, and the other of the water spraying member 300 and the outer tub 100 has an annular groove 330. The annular rib 120 and the annular groove 330 are inserted and matched with each other.

[0075] By adopting the cooperation mode of the annular rib 120 and the annular groove 330, not only can the fixed connection between the water spraying member 300 and the outer barrel 100 be realized to improve the position stability of the water spraying member 300, but also the detachable connection between the water spraying member 300 and the outer barrel 100 can be realized, which is convenient for subsequent disassembly and cleaning of the water spraying member 300. In addition, this cooperation mode can also ensure the cooperation sealing performance between the water spraying member 300 and the outer barrel 100, avoiding water leakage.

[0076] As Figure 4 shown, in this embodiment, an annular groove 330 is provided on the water spraying member 300, and an annular rib 120 protruding towards the annular groove 330 is provided on the outer barrel 100. The annular rib 120 is inserted into the annular groove 330, so that the water spraying member 300 can be connected to the outer barrel 100.

[0077] In some examples, as Figure 4 shown, the annular rib 120 on the outer barrel 100 is arranged close to the water inlet 110. In this way, by inserting the water spraying member 300 on the outer barrel 100, the water spraying member 300 can be arranged to cover the water inlet 110, so as to ensure that the water entering from the water inlet 110 can accurately enter the water passing channel 400, avoiding waste of water resources.

[0078] Optionally, as Figure 4 shown, the annular rib 120 surrounds the water passing channel 400. The annular rib 120 can play a role in blocking the water from flowing towards the outside of the water passing channel 400, so as to ensure that the water entering from the water inlet 110 can only flow along the extending direction of the water passing channel 400, which is beneficial to improving the water inlet efficiency.

[0079] In some examples, a sealing member is arranged at the joint of the annular rib 120 and the annular groove 330. After the annular rib 120 is arranged to surround the water passing channel 400, the sealing member can play a sealing role, avoiding the water in the water passing channel 400 from flowing out from the joint of the annular rib 120 and the annular groove 330, ensuring that the water entering the water passing channel 400 can flow along the established route, and improving the water inlet efficiency. Among them, the sealing member can be made of rubber material.

[0080] In some embodiments, as Figure 4 shown, the water spraying member 300 includes an installation part 310 and a spray head 320. A water passing channel 400 is defined between the installation part 310 and the inner side of the bottom wall of the outer barrel 100.

[0081] Specifically, one of the installation part 310 and the nozzle 320 may form a water tank and the other may close the opening of the water tank, thereby defining a water passage 400; alternatively, water tanks may be respectively provided on the opposite sides of the installation part 310 and the nozzle 320, and the water tank on the installation part 310 and the water tank on the nozzle 320 are arranged opposite to each other to define a water passage 400.

[0082] Adopting the cooperation between the installation part 310 and the bottom wall of the outer barrel 100 to form the water passage 400 can not only ensure that water can flow along a predetermined direction, but also simplify the molding process of the water spraying member 300, which is beneficial to improving production efficiency and reducing production costs.

[0083] As Figure 4 and Figure 7 As shown, the nozzle 320 is connected to the installation part 310. The nozzle 320 defines a water spraying passage 321. The water entering from the water inlet 110 smoothly flows into the water spraying passage 321 along the extending direction of the water passage 400. The water spraying passage 321 can spray water toward the inlet 221 of the water inlet cavity 220, so that the water can smoothly enter the water inlet cavity 220.

[0084] Optionally, the first end of the water spraying passage 321 is connected to the water passage 400, and the second end of the water spraying passage 321 is arranged close to the inlet 221 of the water inlet cavity 220 to transfer the water in the water passage 400 into the water inlet cavity 220.

[0085] Specifically, for the structure of the water spraying passage 321, the cross-sectional area of the first end of the water spraying passage 321 may be larger than the cross-sectional area of the second end of the water spraying passage 321; alternatively, in the direction from the first end to the second end, the cross-sectional area of the water spraying passage 321 may gradually decrease. On the one hand, it ensures that the cross-sectional area of the first end of the water spraying passage 321 is larger, so as to ensure that the water in the water passage 400 can smoothly enter the water spraying passage 321 and increase the water inlet efficiency; on the other hand, for the second end of the water spraying passage 321 with a smaller cross-sectional area, when the water flows through the second end of the water spraying passage 321 toward the inlet 221 of the water inlet cavity 220, the water spraying passage 321 can play a role in boosting pressure, so as to achieve the spraying effect and increase the spraying distance of the water, so that the water in the water spraying passage 321 can be accurately sprayed into the water inlet cavity 220 to avoid waste of water resources.

[0086] In the description of the present invention, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe features, without order or importance.

[0087] As Figure 7 As shown, in some examples, the installation part 310 has a plurality of fixing lugs 311, and the water spraying member 300 is fixed to the outer barrel 100 by fasteners passing through the fixing lugs 311.

[0088] The fixed lug 311 cooperates with the fastener so that the water spraying member 300 can be installed on the outer barrel 100. The plurality of fixed lugs 311 can also increase the number of connection points between the water spraying member 300 and the outer barrel 100, thereby improving the connection reliability between the water spraying member 300 and the outer barrel 100, and enabling the water spraying member 300 to be stably installed on the outer barrel 100. It should be noted that the above fastener can be one of connecting members such as bolts and screws. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0089] Optionally, a connection through-hole is provided on each fixed lug 311, and the fastener passes through the connection through-hole and is fixedly connected to the outer barrel 100 to achieve the fixed connection between the water spraying member 300 and the outer barrel 100.

[0090] Optionally, as Figure 4 shown, an annular groove 330 is formed on the mounting portion 310. It can be seen that the water spraying member 300 of the present application is fixedly connected to the outer barrel 100 through the cooperation of the annular groove 330 and the annular rib 120, and is also connected to the outer barrel 100 through the cooperation of the fixed lug 311 and the fastener. Thus, the water spraying member 300 of the present application is connected to the outer barrel 100 through multiple connection methods, further increasing the connection strength between the water spraying member 300 and the outer barrel 100, so that the position of the water spraying member 300 relative to the outer barrel 100 is stable, and the water spraying member 300 is prevented from shaking during the water flow, thereby ensuring that the water spraying member 300 can effectively transport the water at the water inlet 110 to the water inlet cavity 220.

[0091] In some embodiments of the present invention, as Figure 4 shown, the bottom wall of the outer barrel 100 is provided with a water inlet joint 130 protruding from its outer surface. The water inlet joint 130 is adapted to be connected to an external water source. The water inlet joint 130 defines a water inlet passage 131 and is communicated with the water inlet 110. That is to say, the water inlet joint 130 mainly functions to connect the external water source and the water inlet 110, ensuring that the water of the external water source can flow to the water inlet 110 through the water inlet passage 131 defined by the water inlet joint 130, so as to achieve the purpose of water inlet.

[0092] Optionally, the water inlet joint 130 is formed into a columnar structure for easy connection to the external water source.

[0093] Optionally, the water inlet joint 130 is integrally formed with the outer barrel 100. This reduces the assembly difficulty between the water inlet joint 130 and the outer barrel 100, and the integrally formed water inlet joint 130 and outer barrel 100 will not have the phenomenon of water overflowing from the connection between the water inlet joint 130 and the outer barrel 100, resulting in better sealing performance.

[0094] In some embodiments of the present invention, as Figure 7As shown, the included angle between the extending direction of the water spraying channel 321 and the horizontal direction is an acute angle. In this way, the water spraying channel 321 can be arranged obliquely downward, which is beneficial to the flow of water. Such an arrangement can also increase the coverage area of the water entering the water inlet cavity 220 on the water inlet cavity 220 and ensure that the water can be evenly sprayed into the water inlet cavity 220.

[0095] In some embodiments of the present invention, the water inlet cavity 220 extends circumferentially along the rotation axis of the inner cylinder 200, the inlet 221 of the water inlet cavity 220 is formed in an annular shape, and the center of the annular shape is located on the rotation axis of the inner cylinder 200.

[0096] Since the inner cylinder 200 will drive the water inlet cavity 220 to rotate synchronously during the rotation relative to the outer barrel 100, and since the water spraying member 300 is fixedly connected to the outer barrel 100, by forming the inlet 221 of the water inlet cavity 220 in an annular shape, it can be ensured that the water inlet cavity 220 will not be blocked by the water spraying member 300 during the rotation, that is, it can be ensured that the water inlet cavity 220 can rotate normally. And the above arrangement can also ensure that during the rotation of the water inlet cavity 220, the water spraying member 300 can always spray water towards the water inlet cavity 220 through the inlet 221, ensuring that the laundry treatment device 1000 can work normally.

[0097] In some specific embodiments, the water inlet cavity 220 is formed as an annular cavity, the inlet 221 of the water inlet cavity 220 is arranged close to the inner circumferential wall of the water inlet cavity 220, and in the plane perpendicular to the rotation axis of the inner cylinder 200, the projection of the water spraying channel 321 in the plane is tangent to the projection of the inner circumferential wall of the water inlet cavity 220 in the plane. This can further ensure that the water spraying channel 321 smoothly sprays water into the water inlet cavity 220, and while increasing the spraying distance, it can also ensure that the water can be evenly sprayed into the water inlet cavity 220.

[0098] In some embodiments of the present invention, as Figure 3 shown, the inner cylinder 200 includes a cylinder body 210 and a bracket 230, and the cylinder body 210 defines a laundry treatment cavity 211. The laundry treatment cavity 211 is used for placing the laundry to be cleaned to facilitate subsequent treatment of the laundry.

[0099] In some examples, as Figure 3 shown, the cylinder body 210 is installed on the bracket 230, and the cylinder body 210 is rotatably arranged in the outer barrel 100 through the bracket 230.

[0100] Here, the bracket 230 plays a role in connecting the cylinder body 210 and the outer barrel 100, so that the cylinder body 210 can be arranged in the outer barrel 100, and the bracket 230 can also play a role in supporting the cylinder body 210 to increase the installation stability of the cylinder body 210.

[0101] Optionally, the water inlet chamber 220 is formed on the support 230, which is convenient for molding without damaging the structure of the cylinder body 210. And when the cylinder body 210 rotates relative to the outer tub 100, it can ensure that the water inlet chamber 220 rotates synchronously with the cylinder body 210, so as to convey the water in the water inlet chamber 220 into the laundry treatment chamber 211 in the cylinder body 210, thereby wetting the laundry in the laundry treatment chamber 211, facilitating the cleaning of the laundry, and improving the cleanliness of the laundry cleaning.

[0102] According to some embodiments of the present invention, the laundry treatment device 1000 further includes a rotating shaft 240. One end of the rotating shaft 240 is connected to the inner tub 200 and the other end is rotatably engaged with the outer tub 100. Specifically, one end of the rotating shaft 240 can be connected to the support 230, and the support 230 is rotatably disposed on the outer tub 100 through the rotating shaft 240, so as to ensure that the cylinder body 210 mounted on the support 230 can rotate relative to the outer tub 100.

[0103] In some embodiments, the laundry treatment device 1000 further includes a driving member (not shown in the figure). The driving member is used to drive the rotating shaft 240 to rotate relative to the outer tub 100, thereby driving the support 230 to rotate relative to the outer tub 100, so as to rotatably dispose the cylinder body 210 in the outer tub 100.

[0104] Optionally, the support 230 is disposed on the cylinder body 210, and the central axis of the rotating shaft 240 connected to the support 230 coincides with the rotation axis of the cylinder body 210, ensuring that the cylinder body 210 will not be stuck or unable to rotate during the process of the rotating shaft 240 driving the cylinder body 210 to rotate through the support 230, thereby ensuring that the cylinder body 210 can rotate smoothly.

[0105] In some embodiments, a bearing seat is provided on the bottom wall of the outer tub 100. A first bearing and a second bearing are provided on the bearing seat and arranged at intervals along the axial direction of the outer tub 100. The rotating shaft 240 passes through the first bearing and the second bearing in sequence. The cooperation of the first bearing and the second bearing enables the rotating shaft 240 to stably rotate relative to the outer tub 100, thereby driving the cylinder body 210 to rotate relative to the outer tub 100.

[0106] Optionally, the support 230 includes a connecting ring in the middle and a plurality of connecting brackets. The connecting ring is sleeved on the rotating shaft 240. The plurality of connecting brackets are connected to the connecting ring and arranged at intervals along the circumferential direction of the connecting ring. Each connecting bracket extends radially outward along the connecting ring. The support 230 is connected to the cylinder body 210 through the plurality of connecting brackets, so as to increase the contact area between the support 230 and the cylinder body 210, which can not only improve the connection stability between the support 230 and the cylinder body 210, but also help to ensure the force balance of the cylinder body 210, prevent local overstress of the cylinder body 210 from causing damage to the cylinder body 210, and extend the service life of the cylinder body 210.

[0107] In some embodiments of the present invention, the inner cylinder 200 has a first water outlet, and the outlet 222 of the water inlet chamber 220 is communicated with the first water outlet. The outlet 222 of the water inlet chamber 220 is used to discharge the water in the water inlet chamber 220. Therefore, through the cooperation of the outlet 222 and the first water outlet, it is ensured that the water in the water inlet chamber 220 can smoothly enter the inner cylinder 200, thereby wetting the clothes in the inner cylinder 200 and facilitating the subsequent treatment of the clothes in the inner cylinder 200.

[0108] Optionally, the outlet 222 of the water inlet chamber 220 and the first water outlet are fixedly and sealingly connected, avoiding the loss of water from the connection between the outlet 222 and the first water outlet, which not only improves the water inlet efficiency, but also improves the utilization rate of water, and further improves the wetting efficiency of clothes.

[0109] In some examples, a connecting pipe is provided between the outlet 222 and the first water outlet. One end of the connecting pipe is sealingly connected to the outlet 222, and the other end of the connecting pipe is sealingly connected to the first water outlet. The connecting pipe is used to convey water and define the flow direction of water, so as to ensure that the water flowing out of the outlet 222 of the water inlet chamber 220 can smoothly enter the inner cylinder 200 through the first water outlet.

[0110] In a specific example, the above-mentioned sealing connection can be realized by setting a sealing member, that is, sealing members are provided at the connection between the connecting pipe and the outlet 222 and at the connection between the connecting pipe and the first water outlet. The sealing member can not only avoid water leakage, but also improve the connection strength between the connecting pipe and the outlet 222 and the first water outlet respectively, ensuring that the water at the outlet 222 can smoothly enter the first water outlet through the connecting pipe.

[0111] In some embodiments of the present invention, as Figure 3 shown, the laundry treatment device 1000 further includes a plurality of lifters 500, and the plurality of lifters 500 are arranged inside the side wall of the inner cylinder 200, and the plurality of lifters 500 are arranged at intervals along the circumferential direction of the inner cylinder 200.

[0112] During the process of the laundry treatment device 1000 treating clothes, as the inner cylinder 200 rotates, the plurality of lifters 500 can drive the clothes to rotate simultaneously. On the one hand, the lifters 500 can lift the height of the clothes, and the clothes fall back under the action of gravity, so as to realize the up-and-down beating of the clothes and the flipping of the clothes, achieving the purpose of treating the clothes. On the other hand, the plurality of lifters 500 can increase the contact area between the clothes and the inner cylinder 200, so that the clothes close to the lifters 500 can rub against the lifters 500 to generate a kneading effect, thereby improving the clothes treatment ability of the inner cylinder 200 and enhancing the user experience.

[0113] In some specific examples, three lifting ribs 500 are provided on the inner side of the side wall of the inner cylinder 200. The three lifting ribs 500 are evenly distributed on the inner side of the side wall of the inner cylinder 200, which can improve the washing effect of the laundry treatment device 1000. Of course, in some other examples, the number of the lifting ribs 500 is not limited to the above three. Those skilled in the art can also set the number of the lifting ribs 500 according to parameters such as the volume of the inner cylinder 200. For example, two lifting ribs 500, four lifting ribs 500, etc. can be provided on the inner cylinder 200.

[0114] In some examples, as Figure 3 and Figure 5 shown, the inside of the lifting rib 500 is hollow, and the multiple outlets 222 of the water inlet cavity 220 are in one-to-one correspondence and communication with the hollow parts of the multiple lifting ribs 500. The outlet 222 is used to realize the communication between the inside of the lifting rib 500 and the water inlet cavity 220, ensuring that the water entering the water inlet cavity 220 can smoothly enter the inside of the lifting rib 500 through the outlet 222, so as to facilitate the subsequent input of water into the inner cylinder 200 and achieve the purpose of treating the clothes.

[0115] Optionally, as Figure 5 shown, a second water outlet is defined between the lifting rib 500 and the inner cylinder 200, and the second water outlet is in communication with the hollow part of the lifting rib 500. In this way, the water entering the hollow part of the lifting rib 500 through the outlet 222 can flow into the inside of the inner cylinder 200 through the second water outlet, achieving the purpose of conveying water into the inner cylinder 200 to wet the clothes in the inner cylinder 200.

[0116] In some examples, a part of the structure of the lifting rib 500 can be spaced from the inner cylinder 200 to form a second water outlet, which is convenient for realizing the communication between the hollow part of the lifting rib 500 and the inner cavity of the inner cylinder 200.

[0117] It should be noted that by defining a second water outlet between the lifting rib 500 and the inner cylinder 200, there is no need to open holes on the surface of the lifting rib 500, that is, the surface of the lifting rib 500 can be made into a non-porous structure, which not only simplifies the processing process of the lifting rib 500 and reduces the manufacturing difficulty, but also can avoid the surface of the lifting rib 500 from wearing the clothes.

[0118] Optionally, the lifting rib 500 itself defines a second water outlet that communicates with the hollow part of the lifting rib 500. The inside of the lifting rib 500 is in communication with the inner cavity of the inner cylinder 200 through the second water outlet on its own structure. Such a setting can also realize the diversion of the water inside the lifting rib 500 to the inner cylinder 200 to achieve the purpose of water inlet.

[0119] It should be noted that by defining the second water outlet on the structure of the lifting rib 500 itself, there is no need to define a second water outlet communicating with the hollow part of the lifting rib 500 between the lifting rib 500 and the inner cylinder 200. Thus, the lifting rib 500 can be closely attached to the inner cylinder 200 to improve the position stability of the lifting rib 500, thereby effectively improving the cleaning degree of clothing treatment.

[0120] From this, it can be seen that the technical solution of the present application is applicable to the clothing treatment device 1000 with a perforated inner cylinder (the inner cylinder 200 has a first water outlet), and is also applicable to the clothing treatment device 1000 with a non-perforated inner cylinder (a plurality of lifting ribs 500 are arranged on the inner side of the side wall of the inner cylinder 200, and a second water outlet communicating with the hollow part of the lifting rib 500 is defined between the lifting rib 500 and the inner cylinder 200, or the second water outlet communicating with the hollow part of the lifting rib 500 is defined on the lifting rib 500 itself), and has little limitation.

[0121] Of course, in some other examples, the second water outlet can be defined both on the structure of the lifting rib 500 itself and between the lifting rib 500 and the inner cylinder 200, so as to increase the number of the second water outlets. Multiple second water outlets simultaneously convey water towards the inner cylinder 100, which can also improve the conveying efficiency and further improve the clothing wetting efficiency.

[0122] Optionally, the lifting rib 500 extends along the axial direction of the inner cylinder 200, which can increase the area of the lifting rib 500, ensure that the lifting rib 500 can effectively drive the clothing to flip and increase the contact area between the inner cylinder 200 and the clothing, achieve the effect of treating the clothing, and improve the cleaning degree of clothing treatment.

[0123] Optionally, one end of the lifting rib 500 extends to the bottom wall of the inner cylinder 200 and is in sealed cooperation with the inner cylinder 200. While ensuring that the lifting rib 500 can be stably connected to the inner cylinder 200, it can also ensure that the water entering the lifting rib 500 does not flow out from the connection between the lifting rib 500 and the inner cylinder 200, thereby improving the utilization rate of water and the water inlet efficiency.

[0124] In some examples, a seal can be provided at the connection between the lifting rib 500 and the inner cylinder 200. The seal mainly plays a sealing role to avoid water leakage problems.

[0125] As Figure 5 shown, in some examples, the lifting rib 500 has an interface end 510, and the inner cylinder 200 has a mating groove 250. The mating groove 250 extends along the circumference of the outlet 222 of the water inlet cavity 220. The interface end 510 is inserted into the mating groove 250, so that the lifting rib 500 is installed in the inner cylinder 200, realizing the fixed connection between the lifting rib 500 and the inner cylinder 200 to improve the position stability of the lifting rib 500.

[0126] Optionally, asFigure 5 As shown, the interface end 510 defines a water outlet 511, and the water outlet 511 communicates with the hollow part of the lifting rib 500. When the interface end 510 is inserted into the mating groove 250, it is ensured that the water outlet 511 is arranged facing the outlet 222. In this way, the water in the water inlet chamber 220 can flow into the inside of the lifting rib 500 through the water outlet 511, and then the water entering the inside of the lifting rib 500 flows into the inside of the inner cylinder 200 through the second water outlet, achieving the purpose of conveying water towards the inner cylinder 200 to wet the clothes inside the inner cylinder 200.

[0127] Optionally, a seal is provided at the connection between the mating groove 250 and the interface end 510. While ensuring that the interface end 510 of the lifting rib 500 can be stably connected to the inner cylinder 200, it can also ensure that the water flowing from the outlet 222 towards the water outlet 511 will not flow out through the connection between the mating groove 250 and the interface end 510, thereby improving the utilization rate of water and the water inlet efficiency.

[0128] In summary, for the laundry treatment device 1000 of the present application, when water needs to be introduced into the laundry treatment chamber 211, the water from the external water source first enters the detergent dispensing component 800 through the water inlet valve 900 and one of the water inlet pipes 700. The water entering the detergent dispensing component 800 impacts and dissolves the cleaning medium in the detergent dispensing component 800. Subsequently, the water and the cleaning medium together flow into the water inlet 110 through the other water inlet pipe 700. The water flowing into the water inlet 110 flows into the water spraying channel 321 through the water passing channel 400, and then is sprayed towards the inlet 221 of the water inlet chamber 220 through the water spraying channel 321 to spray the water into the water inlet chamber 220.

[0129] In some examples, if a first water outlet is formed on the inner cylinder 200, the water sprayed into the water inlet chamber 220 can directly flow into the inside of the inner cylinder 200 through the outlet 222 and the first water outlet to achieve the purpose of water inlet; in other examples, if the lifting rib 500 is formed on the inner cylinder 200, the water sprayed into the water inlet chamber 220 can flow into the inside of the lifting rib 500 through the outlet 222 and the water outlet 511. Subsequently, the water located inside the lifting rib 500 flows into the inside of the inner cylinder 200 through the second water outlet to achieve the purpose of water inlet.

[0130] It can be seen from this that during the water inlet process of the laundry treatment device 1000 of the present application, the external water source directly enters the water inlet chamber 220 through the water spraying member 300 connected to the water inlet 110, and then enters the laundry treatment chamber 211 through the water inlet chamber 220, avoiding the water flowing through the outer tub 100 first and then into the inner cylinder 200. This not only shortens the flowing path of the water, improves the water inlet efficiency, but also avoids the water entering the inner cylinder 200 being contaminated with dirt and bacteria in the outer tub 100, enhancing the user experience.

[0131] A specific embodiment of the clothing treatment device 1000 of the present invention will be described below in conjunction with the accompanying drawings. The clothing treatment device 1000 here can be a drum washing machine or a drum washing and drying integrated machine.

[0132] As Figure 1 and Figure 3 shown, the clothing treatment device 1000 includes an outer tub 100, an inner tub 200, a water spraying member 300, a lifting rib 500, a water inlet pipe 700, a detergent dispensing component 800, and a water inlet valve 900.

[0133] As Figure 3 shown, the inner tub 200 includes a tub body 210 and a bracket 230. The tub body 210 defines a clothing treatment cavity 211. The tub body 210 is installed on the bracket 230. The tub body 210 is rotatably arranged in the outer tub 100 through the bracket 230. A water inlet cavity 220 is formed on the bracket 230 and communicates with the clothing treatment cavity 211.

[0134] As Figure 1 and Figure 2 shown, both the detergent dispensing component 800 and the water inlet valve 900 are arranged above the outer tub 100. The water inlet valve 900 is used to connect to an external water source. The detergent dispensing component 800 is connected to the water inlet valve 900 through the water inlet pipe 700. The water inlet valve 900 is used to control the flow of water from the external water source towards the detergent dispensing component 800. The water flowing to the detergent dispensing component 800 dissolves the detergent in the detergent dispensing component 800.

[0135] As Figure 3 shown, a water inlet joint 130 protruding from the outer surface is provided on the bottom wall of the outer tub 100. One end of the water inlet joint 130 communicates with the detergent dispensing component 800 through the water inlet pipe 700. The water inlet joint 130 defines a water inlet passage 131 and the other end of the water inlet joint 130 communicates with the water inlet 110. After the water flowing to the detergent dispensing component 800 dissolves the detergent, it flows into the water inlet 110 through the water inlet pipe 700 and the water inlet joint 130.

[0136] As Figure 4 shown, the water spraying member 300 includes a mounting portion 310 and a spray head 320. A water passage 400 is defined between the mounting portion 310 and the inner side of the bottom wall of the outer tub 100. The spray head 320 is connected to the mounting portion 310 and the spray head 320 defines a water spraying passage 321. The included angle between the extending direction of the water spraying passage 321 and the horizontal direction is an acute angle. The water passage 400 communicates the water inlet 110 and the water spraying passage 321. The water spraying passage 321 communicates with the inlet 221 of the water inlet cavity 220. In this way, the water entering the water inlet 110 can flow into the water spraying passage 321 through the water passage 400, and the water spraying passage 321 then sprays the water towards the inlet 221 of the water inlet cavity 220.

[0137] AsFigure 5 As shown, the inside of the lifting rib 500 is hollow. The lifting rib 500 has an interface end 510. The interface end 510 defines a water passing port 511 that communicates with the hollow part of the lifting rib 500. A second water outlet that communicates with the hollow part of the lifting rib 500 is defined between the lifting rib 500 and the inner cylinder 200. The hollow part of the lifting rib 500 communicates with the water inlet cavity 220 through the second water outlet and the outlet 222 of the water inlet cavity 220. The water sprayed into the water inlet cavity 220 through the inlet 221 sequentially enters the inside of the lifting rib 500 through the outlet 222 and the water passing port 511. Finally, the water inside the lifting rib 500 flows into the laundry treatment cavity 211 through the second water outlet, achieving the purpose of feeding water towards the laundry treatment cavity 211 to wet the laundry in the laundry treatment cavity 211.
