Description

Technical Field

[0001] The present invention belongs to the technical field of clothing treatment, and particularly relates to a clothing treatment device. Background Art

[0002] In the existing clothing treatment device, when the inner drum of the clothing treatment device is a perforation-free inner drum, it is usually necessary to directly put the detergent into the clothing treatment cavity manually, which easily causes the phenomenon that the detergent is not fully dissolved; when the inner drum of the clothing treatment device is a perforated inner drum, the water from the external water source will first enter the detergent box to dissolve the detergent, and then the water and the detergent will enter the outer tub together. The water and the detergent entering the outer tub enter the inner drum through the holes on the body of the inner drum to wet and wash the clothes.

[0003] However, the above water inlet mode of the perforated inner drum easily causes part of the detergent to remain between the inner drum and the outer tub, resulting in a decrease in the effective utilization rate of the detergent. While causing waste of the detergent, it also reduces the quality of clothing treatment. Moreover, the detergent entering the inner drum after passing through the outer tub will be doped with dirt, bacteria, etc. in the outer tub, resulting in dirt and bacteria adhering to the clothes and endangering the health of human skin. Summary of the Invention

[0057] 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.

[0058] 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. These 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. Therefore, it should not be construed as a limitation to the present invention.

[0059] The following describes the laundry treating apparatus 1000 according to an embodiment of the present invention with reference to the accompanying drawings of the specification.

[0060] As Figures 1 - 10 shown, the laundry treating apparatus 1000 according to an embodiment of the present invention includes: an outer tub 100, an inner tub 200, a water spraying member 300, and a detergent dispensing assembly 800.

[0061] The inner tub 200 is rotatably disposed within 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, and the water inlet chamber 220 communicates with the laundry treating chamber 211.

[0062] 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 Figure 11 ), and the water spraying passage 321 communicates with the inlet 221 of the water inlet chamber 220, facilitating the conveyance of water, detergent, etc. into the water inlet chamber 220 through the inlet 221.

[0063] The detergent dispensing assembly 800 has a detergent dispensing chamber 811, a first water inlet 820, and a dispensing port 830. The first water inlet 820 communicates with the detergent dispensing chamber 811, and the dispensing port 830 communicates with the water spraying passage 321.

[0064] When 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 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.

[0065] According to the clothing treatment device 1000 of the embodiment of the present invention, by providing a water inlet chamber 220 communicating with the clothing treatment chamber 211, the water and detergent entering the water inlet chamber 220 can enter the clothing treatment chamber 211. For example, when the water spraying member 300 sprays water into the water inlet chamber 220, the water entering the water inlet chamber 220 can directly flow through the water inlet chamber 220 into the clothing treatment chamber 211, so as to achieve the purpose of supplying water to the clothing treatment chamber 211, thereby wetting the clothes in the clothing treatment chamber 211 and facilitating subsequent cleaning of the clothes.

[0066] The water spraying channel 321 of the water spraying member 300 is arranged to communicate with the inlet 221 of the water inlet chamber 220. It can also be understood that the water spraying channel 321 of the water spraying member 300 is used to convey water and / or detergent to the inlet 221 of the water inlet chamber 220, so as to achieve the purpose of conveying water and / or detergent to the water inlet chamber 220. Since the water inlet chamber 220 communicates with the clothing treatment chamber 211, water, detergent, etc. can be conveyed into the clothing treatment chamber 211, facilitating the treatment of the clothes in the clothing treatment chamber 211.

[0067] It should be noted that by arranging the water spraying member 300 on the outer tub 100, the outer tub 100 can play a role in supporting the water spraying member 300, so as to improve the position stability of the water spraying member 300 and ensure that the water spraying channel 321 of the water spraying member 300 can stably communicate with the inlet 221 of the water inlet chamber 220.

[0068] By providing a detergent dispensing component 800, when the detergent dispensing chamber 811 stores detergent, the clear water from an external water source enters the detergent dispensing chamber 811 through the first water inlet 820 to dissolve the detergent in the detergent dispensing chamber 811. After dissolution, the detergent follows the water flow and is discharged from the dispensing port 830. Among them, Figure 7 shows the flow path of the clear water from the external water source entering the detergent dispensing chamber 811 through the first water inlet 820, Figure 7 and the arrow marked in it indicates the flow direction of the clear water.

[0069] Since the dispensing port 830 communicates with the water spraying channel 321, the water, detergent, etc. discharged from the dispensing port 830 can be directly conveyed through the water spraying channel 321 to the inlet 221 of the water inlet chamber 220 and flow into the water inlet chamber 220 through the inlet 221 of the water inlet chamber 220. Since the water inlet chamber 220 communicates with the clothing treatment chamber 211, the purpose of conveying detergent to the clothing treatment chamber 211 is achieved, and the detergent conveyed into the clothing treatment chamber 211 participates in the washing to improve the cleanliness of the clothes after washing.

[0070] It can be seen from this that for the laundry treatment device 1000 of the present application, when washing clothes, the detergent is directly transported into the laundry treatment chamber 211 through the water spraying channel 321, avoiding the detergent flowing through the outer tub 100 first and then flowing into the laundry treatment chamber 211. On the one hand, it solves the technical problem that part of the detergent will stay between the inner tub 200 and the outer tub 100, and the utilization rate of the detergent is relatively low, so as to effectively improve the utilization rate of the detergent, avoid waste of the detergent, save the use cost of the detergent, and at the same time improve the quality of laundry treatment; on the other hand, it also avoids the detergent entering the laundry treatment chamber 211 being doped with dirt and bacteria in the outer tub 100, so as to ensure that the detergent entering the laundry treatment chamber 211 is free of dirt and bacteria, ensure the cleanliness of the laundry treatment chamber 211, so that no bacteria remain on the clothes, ensure the health of the human body, and improve the user experience.

[0071] It should be noted that for the convenience of description, the cleaning medium placed in the detergent dispensing chamber 811 is defined as detergent above. In some examples, the cleaning medium includes but is not limited to detergent, bleach, fabric softener or disinfectant.

[0072] It is not difficult for those skilled in the art to understand that when clean water enters the detergent dispensing chamber 811 to dissolve the detergent and is discharged from the dispensing port 830, it will drive the detergent to be discharged together, so that the detergent can participate in the washing. Therefore, the water described below can be understood as water with detergent.

[0073] It can be understood that compared with the prior art, for the laundry treatment device 1000 of the present application, by connecting the dispensing port 830 of the detergent dispensing component 800 with the water spraying channel 321 and the water spraying channel 321 is connected to the inlet 221 of the water inlet chamber 220, the detergent discharged from the dispensing port 830 can be directly transported into the water inlet chamber 220 without flowing through the space between the outer tub 100 and the inner tub 200 and then flowing into the laundry treatment chamber 211. While improving the utilization rate of the detergent, it can also ensure that the detergent entering the laundry treatment chamber 211 is free of dirt and bacteria and improve the quality of laundry treatment.

[0074] Optionally, 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. To improve the position stability of the detergent dispensing component 800, and since the water spraying member 300 is provided on the outer tub 100, therefore, setting the detergent dispensing component 800 above the outer tub 100 can also ensure that the detergent dispensing component 800 is arranged close to the water spraying member 300, which is convenient for connecting the dispensing port 830 with the water spraying channel 321.

[0075] In some embodiments of the present invention, the wall surface of the detergent dispensing chamber 811 forms a closed surface except for the positions of the first water inlet 820 and the dispensing port 830.

[0076] That is to say, the wall surface of the detergent dispensing chamber 811, except for the positions of the first water inlet 820 and the dispensing port 830, is a sealing surface, so that the detergent dispensing chamber 811 forms a relatively sealed chamber, avoiding air leakage and water leakage problems, ensuring that the water entering from the first water inlet 820 is mixed with the detergent in the detergent dispensing chamber 811 and discharged from the dispensing port 830 and dispensed into the inner tub 200, effectively improving the utilization rate of the detergent and the quality of clothing washing.

[0077] In some embodiments of the present invention, as Figure 2 shown, the detergent dispensing assembly 800 includes a detergent placement box 850, a detergent dissolution box 810, and a dispensing pump 840. The detergent placement box 850 has a detergent accommodation chamber for storing detergent.

[0078] In some examples, the detergent placement box 850 is not limited to having only one detergent accommodation chamber. The interior of the detergent placement box 850 may include a plurality of independently arranged detergent accommodation chambers, and each detergent accommodation chamber is used to store a kind of detergent. For example, the detergent placement box 850 includes three detergent accommodation chambers, one of which is used to store laundry detergent, and the other two detergent accommodation chambers are respectively used to store fabric softener and disinfectant.

[0079] Optionally, as Figure 1 shown, the detergent dissolution box 810 is provided in the detergent placement box 850. Since the detergent placement box 850 is provided with a detergent accommodation chamber for storing detergent, such a setting facilitates the delivery of the detergent into the detergent dissolution box 810.

[0080] Optionally, as Figure 1 shown, the detergent dissolution box 810 is connected to the detergent placement box 850 to ensure the stable position of the detergent dissolution box 810 relative to the detergent placement box 850, thereby realizing the delivery of the detergent from the detergent placement box 850 to the detergent dissolution box 810. The connection mentioned here can be a detachable connection, such as a bolt connection, a snap connection, etc., or a non-detachable connection, such as a welding connection, an adhesive connection, etc. The specific connection method is not limited, as long as the position of the detergent dissolution box 810 relative to the detergent placement box 850 is stable and the detergent in the detergent placement box 850 can be delivered into the detergent dissolution box 810.

[0081] Optionally, as Figure 1 and Figure 2As shown, the detergent dissolution box 810 defines a detergent dispensing cavity 811, and a dispensing pump 840 is used to convey the detergent in the detergent containing cavity to the detergent dispensing cavity 811. In this way, the water entering the detergent dispensing cavity 811 from the first water inlet 820 can dissolve the detergent in the detergent dispensing cavity 811, facilitating subsequent conveyance into the laundry treatment cavity 211.

[0082] In a specific example, after the dispensing pump 840 is started, the selected detergent can be pumped from the corresponding detergent containing cavity into the detergent dispensing cavity 811 by the suction of the dispensing pump 840. Subsequently, an external water source enters the detergent dispensing cavity 811 through the first water inlet 820 and dissolves the detergent in the detergent dispensing cavity 811. After dissolution, the detergent flows towards the water spraying channel 321 through the dispensing port 830.

[0083] Optionally, as Figure 1 shown, the detergent placement box 850 is provided above the outer tub 100. This facilitates the user to pull out the detergent placement box 850 to dispense detergent into the detergent placement box 850.

[0084] Optionally, as Figure 1 shown, both the detergent dissolution box 810 and the dispensing pump 840 are located behind the detergent placement box 850, and the detergent dissolution box 810 is provided above the dispensing pump 840. Since the user pulls out the detergent placement box 850 towards the front of the outer tub 100 during the process of dispensing detergent, both the detergent dissolution box 810 and the dispensing pump 840 are arranged behind the detergent placement box 850 to ensure that the detergent dissolution box 810 and the dispensing pump 840 do not obstruct the extraction of the detergent placement box 850, thus enabling the smooth extraction of the detergent placement box 850. Moreover, the detergent dissolution box 810 and the dispensing pump 840 arranged behind the detergent placement box 850 can make the detergent dissolution box 810 and the dispensing pump 840 both close to the water spraying member 300, facilitating the layout of the water circuit and reducing the length of the water circuit.

[0085] Optionally, the rear wall of the detergent placement box 850 is provided with a liquid outlet (not shown in the figure). As Figure 2 shown, the bottom wall of the detergent dissolution box 810 is provided with a liquid inlet 812, and the dispensing pump 840 is used to convey the detergent flowing out from the liquid outlet to the liquid inlet 812. This serves the purpose of conveying the detergent in the detergent placement box 850 into the detergent dispensing cavity 811.

[0086] Optionally, as Figure 2As shown, a first diversion channel 8111 and a second diversion channel 8112 that are parallel to each other are formed in the detergent dispensing chamber 811. One end of the first diversion channel 8111 communicates with one end of the second diversion channel 8112. The other end of the first diversion channel 8111 forms a first water inlet 820, and the other end of the second diversion channel 8112 forms a dispensing port 830. The first diversion channel 8111 and the second diversion channel 8112 cooperate to define the flow direction of water. In this way, the water entering the detergent dispensing chamber 811 from the first water inlet 820 can flow along the extension direction of the first diversion channel 8111 and flow into the second diversion channel 8112. Since one end of the second diversion channel 8112 has a dispensing port 830, the water in the second diversion channel 8112 can flow through the dispensing port 830 towards the water spraying channel 321, achieving the purpose of delivering water towards the water spraying channel 321.

[0087] Optionally, as Figure 2 shown, a liquid inlet 812 communicating with the pumping outlet of the dispensing pump 840 is formed on the bottom wall of the second diversion channel 8112. The dispensing pump 840 and the liquid inlet 812 cooperate to transport the detergent in the detergent placement box 850 into the second diversion channel 8112. Since one end of the second diversion channel 8112 forms a dispensing port 830, under the action of the water flow, it can be ensured that the detergent entering the detergent dispensing chamber 811 can flow towards the water spraying channel 321, preventing the detergent from staying in the detergent dispensing chamber 811 and improving the utilization rate of the detergent.

[0088] In some embodiments of the present invention, as Figures 2 - 4 shown, the dispensing port 830 is communicated with the water spraying channel 321 through a dispensing pipe 700. The dispensing pipe 700 guides the water flowing from the dispensing port 830 towards the water spraying channel 321, ensuring that the water discharged from the dispensing port 830 can accurately flow into the water spraying channel 321, and then be transported towards the laundry treatment chamber 211 through the water spraying channel 321.

[0089] Optionally, one end of the dispensing pipe 700 is connected to the dispensing port 830, and the other end of the dispensing pipe 700 is connected to the water spraying channel 321 to achieve the communication between the dispensing port 830 and the water spraying channel 321. Seals are provided at both ends of the dispensing pipe 700. The seals are used to ensure the sealing performance between the dispensing pipe 700 and the dispensing port 830 and between the dispensing pipe 700 and the water spraying channel 321, ensuring that water will not overflow towards the outside of the dispensing pipe 700 or the water spraying channel 321 during the transportation process, thereby improving the utilization rate of the detergent, saving the use cost of the detergent, and improving the laundry cleaning quality.

[0090] Optionally, as Figure 4As shown, the water spraying member 300 is disposed inside the bottom wall of the outer tub 100. Through 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 treating 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.

[0091] 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. Such an arrangement can ensure that the water spraying member 300 can be disposed close to the detergent dispensing chamber 811, facilitating the delivery of the dissolved detergent in the detergent dispensing chamber 811 into the water spraying passage 321 of the water spraying member 300.

[0092] Optionally, as Figure 1 shown, a limiting groove 130 is provided on the outer side of the bottom wall of the outer tub 100, and at least a part of the dispensing pipe 700 is disposed in the limiting groove 130.

[0093] The limiting groove 130 here can limit the position of the dispensing pipe 700, improve the position stability of the dispensing pipe 700, prevent the dispensing pipe 700 from shaking during the operation of the laundry treating apparatus 1000, and can avoid the breakage of the dispensing pipe 700 due to the shaking of the laundry treating apparatus 1000, thereby extending the service life of the dispensing pipe 700. In addition, during the installation process of the dispensing pipe 700, the installer can quickly locate the installation position of the dispensing pipe 700 through the limiting groove 130, so as to reduce the installation difficulty of the dispensing pipe 700 and improve the installation efficiency.

[0094] Optionally, as Figure 1 shown, a reinforcing structure 140 is provided on the outer side of the bottom wall of the outer tub 100. The reinforcing structure 140 is used to increase the structural strength of the outer tub 100, avoid the deformation of the outer tub 100 after long-term use, and extend the service life of the outer tub 100.

[0095] Optionally, as Figure 3 shown, the reinforcing structure 140 includes a circumferential reinforcing rib 141 and a radial reinforcing rib 142. The radial reinforcing rib 142 extends along the radial direction of the outer tub 100, and there are a plurality of radial reinforcing ribs 142. The plurality of radial reinforcing ribs 142 are arranged at intervals around the axis of the outer tub 100 in a divergent shape to increase the structural strength of the outer tub 100.

[0096] In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0097] Optionally, as Figure 3As shown, the circumferential reinforcing rib 141 extends around the axis of the outer barrel 100 to form a ring. The circumferential reinforcing rib 141 is connected to the radial reinforcing rib 142. The cooperation of the circumferential reinforcing rib 141 and the radial reinforcing rib 142 can further optimize the structure of the reinforcing structure 140 and improve the strength of the bottom wall of the outer barrel 100.

[0098] Optionally, at a position close to the detergent dispensing assembly 800, the circumferential reinforcing rib 141 is discontinuously arranged to form a limiting groove 130. The dispensing pipe 700 is arranged in the limiting groove 130. While improving the structural stability of the dispensing pipe 700, the communication between the dispensing port 830 and the water spraying channel 321 can be realized.

[0099] It should be noted that by discontinuously arranging a part of the structure of the circumferential reinforcing rib 141 to form the limiting groove 130, it is not necessary to separately open a groove on the outer side of the bottom wall of the outer barrel 100 for the limiting groove 130. While ensuring that the outer barrel 100 has sufficient structural strength, the structure of the outer barrel 100 is simplified and the production difficulty of the outer barrel 100 is reduced.

[0100] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the laundry treatment device 1000 further includes a water inlet valve 900. The water inlet valve 900 is adapted to be connected to an external water source. The water inlet valve 900 is connected to the first water inlet 820 through a water inlet pipe 600. The cooperation of the water inlet valve 900 and the water inlet pipe 600 can deliver the clear water provided by the external water source to the detergent dispensing cavity 811, thereby dissolving the detergent in the detergent dispensing cavity 811, and enabling the dissolved detergent to enter the laundry treatment device 1000 to wet the clothes placed in the laundry treatment device 1000, facilitating the cleaning treatment of the clothes in the laundry treatment device 1000.

[0101] Optionally, one end of the water inlet pipe 600 is connected to the water inlet valve 900, and the other end of the water inlet pipe 600 is connected to the first water inlet 820 to realize the communication between the water inlet valve 900 and the first water inlet 820. Sealing members can be arranged at both ends of the water inlet pipe 600 to ensure the sealing performance between the water inlet pipe 600 and the water inlet valve 900 and between the water inlet pipe 600 and the first water inlet 820, ensuring that water will not overflow externally towards the water inlet pipe 600 or towards the first water inlet 820 during the transportation process, thereby improving the water transportation efficiency and avoiding the waste of water resources.

[0102] In some embodiments of the present invention, as Figure 4 and Figure 9As shown, the water spraying member 300 is disposed on the bottom wall of the outer barrel 100, enabling the water spraying member 300 to be disposed close to both the dosing pipe 700 and the water inlet chamber 220 simultaneously, so as to reduce the volume of the water spraying member 300 and ensure that the water spraying member 300 can effectively convey the water at the dosing pipe 700 into the water inlet chamber 220.

[0103] Optionally, as Figure 4 and Figure 5 shown, a water passing channel 400 is defined between the water spraying member 300 and the outer barrel 100. The water passing channel 400 communicates the water spraying channel 321 and the dosing opening 830. The water passing channel 400 is used to realize the communication between the water spraying channel 321 and the dosing opening 830 and guide the flow of water, ensuring that the water can flow along a predetermined route, that is, ensuring that the water discharged from the dosing opening 830 can be smoothly conveyed into the water spraying channel 321 and then flow into the inlet 221 of the water inlet chamber 220 through the water spraying channel 321.

[0104] Optionally, as Figure 4 and Figure 5 shown, the outer barrel 100 has a second water inlet 110. The water passing channel 400 communicates the water spraying channel 321 and the second water inlet 110. The second water inlet 110 is adapted to be connected to the dosing pipe 700. Here, it means that one end of the dosing pipe 700 is connected to the dosing opening 830 and the other end of the dosing pipe 700 is connected to the second water inlet 110. With such a setting, the water output from the dosing opening 830 can be conveyed to the second water inlet 110 through the dosing pipe 700, and the water entering the second water inlet 110 is then conveyed into the water spraying channel 321 through the water passing channel 400 to realize the communication between the water spraying channel 321 and the dosing opening 830, ensuring that the water output from the dosing opening 830 can smoothly enter the water spraying channel 321.

[0105] In some examples, as Figure 5 shown, the water spraying member 300 includes a mounting portion 310 and a nozzle 320. A water passing channel 400 is defined between the mounting portion 310 and the inner side of the bottom wall of the outer barrel 100.

[0106] Specifically, it can be that one of the mounting portion 310 and the nozzle 320 forms a water tank and the other closes the opening of the water tank, thereby defining the water passing channel 400; it can also be that water tanks are respectively provided on the opposite sides of the mounting portion 310 and the nozzle 320, and the water tanks on the mounting portion 310 and the nozzle 320 are arranged oppositely to define the water passing channel 400.

[0107] Adopting the mounting portion 310 to cooperate with the bottom wall of the outer barrel 100 to form the water passing channel 400 can not only ensure that the water can flow along a predetermined direction, but also simplify the forming process of the water spraying member 300, which is beneficial to improving production efficiency and reducing production costs.

[0108] AsFigure 5 and Figure 7 As shown in Figure 7 , the nozzle 320 is connected to the mounting portion 310, and the nozzle 320 defines a water spraying channel 321. The water entering from the second water inlet 110 smoothly flows into the water spraying channel 321 along the extending direction of the water passing channel 400. The water spraying channel 321 can define the water to be sprayed toward the inlet 221 of the water inlet cavity 220, so that the water can smoothly enter the water inlet cavity 220.

[0109] Optionally, the first end of the water spraying channel 321 is connected to the water passing channel 400, and the second end of the water spraying channel 321 is arranged close to the inlet 221 of the water inlet cavity 220 to transfer the water in the water passing channel 400 into the water inlet cavity 220.

[0110] Specifically, for the structure of the water spraying channel 321, it can be that the cross-sectional area of the first end of the water spraying channel 321 is larger than the cross-sectional area of the second end of the water spraying channel 321, or it can be that in the direction from the first end to the second end, the cross-sectional area of the water spraying channel 321 decreases successively. On the one hand, it ensures that the cross-sectional area of the first end of the water spraying channel 321 is larger, so as to ensure that the water in the water passing channel 400 can smoothly enter the water spraying channel 321 and increase the water inlet efficiency; on the other hand, for the second end of the water spraying channel 321 with a smaller cross-sectional area, when the water flows through the second end of the water spraying channel 321 toward the inlet 221 of the water inlet cavity 220, the water spraying channel 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 channel 321 can be accurately sprayed into the water inlet cavity 220, avoiding the waste of water resources and improving the utilization rate of the detergent.

[0111] As Figure 7 and Figure 11 shown in Figure 11 , in some examples, the spraying member 300 has a plurality of fixing lugs 311, and the spraying member 300 is fixed to the outer tub 100 by fasteners passing through the fixing lugs 311.

[0112] The cooperation of the fixing lugs 311 and the fasteners enables the spraying member 300 to be installed on the outer tub 100. The plurality of fixing lugs 311 can also increase the number of connection points between the spraying member 300 and the outer tub 100, thereby improving the connection reliability between the spraying member 300 and the outer tub 100, and enabling the spraying member 300 to be stably installed on the outer tub 100. It should be noted that the above-mentioned fasteners can be one of connecting members such as bolts and screws.

[0113] Of course, in some other examples, it is not limited to defining the water passing channel 400 between the spraying member 300 and the outer tub 100. The spraying member 300 itself can also define the water passing channel 400 to define the flow direction of the water.

[0114] In some other examples, as Figure 10As shown, the water spraying member 300 includes a bent pipe and a spray head 320. The bent pipe is disposed through the outer tub 100. One end of the bent pipe defines a water inlet 312, and the spray head 320 is communicated with the other end of the bent pipe. The spray head 320 defines a water spraying channel 321.

[0115] Wherein, the bent pipe includes a first pipe section 313, a second pipe section 314, a third pipe section 315 and the spray head 320. A water passing channel 400 is defined in each of the first pipe section 313, the second pipe section 314 and the third pipe section 315. The first pipe section 313 extends along the axial direction of the outer tub 100 and is disposed through the bottom wall of the outer tub 100. The first pipe section 313 is used to ensure that both ends of the water spraying member 300 are respectively located inside and outside the outer tub 100, so that the water spraying member 300 can communicate the dosing port 830 and the inlet 221 of the water inlet chamber 220, so as to spray the detergent output from the dosing port 830 towards the inlet 221 of the water inlet chamber 220, achieving the purpose of conveying the detergent towards the inner tub 200.

[0116] Optionally, the outer tub 100 has an avoidance opening. The first pipe section 313 is disposed through the bottom wall of the outer tub 100 through the avoidance opening so that both ends of the water spraying member 300 can be respectively located inside and outside the outer tub 100.

[0117] Optionally, as Figure 10 shown, the second pipe section 314 is disposed inside the outer tub 100. One end of the second pipe section 314 is connected to one end of the first pipe section 313. The other end of the second pipe section 314 extends towards the inlet 221 of the water inlet chamber 220, and the other end of the second pipe section 314 is connected to the spray head 320. The spray head 320 defines a water spraying channel 321. Since the second pipe section 314 is connected to the first pipe section 313 and extends towards the inlet 221 of the water inlet chamber 220, on the one hand, the second pipe section 314 ensures that the spray head 320 can be disposed close to the inlet 221 of the water inlet chamber 220, so as to ensure that the water spraying channel 321 in the spray head 320 can spray the detergent into the water inlet chamber 220; on the other hand, the second pipe section 314 is used to define the flow direction of the detergent entering the second pipe section 314, ensuring that the detergent can flow towards the spray head 320, so that the spray head 320 can spray the detergent into the water inlet chamber 220.

[0118] Optionally, as Figure 10 shown, the third pipe section 315 is disposed outside the outer tub 100. One end of the third pipe section 315 defines a water inlet 312, and the other end of the third pipe section 315 is communicated with the other end of the first pipe section 313. The third pipe section 315 is used to introduce the detergent output from the dosing port 830 into the water spraying member 300 and define the flow direction of the detergent entering the water spraying member 300, ensuring that the detergent can flow towards the first pipe section 313, so that the spray head 320 can spray the detergent into the water inlet chamber 220.

[0119] With the above settings, the water spraying member 300 itself defines a water passing channel 400.

[0120] In the description of the present invention, the features defined as "first", "second", and "third" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe the features, without order or importance.

[0121] Optionally, one end of the third pipe section 315 defining the water inlet / outlet 312 is connected to the dosing pipe 700, and the other end of the third pipe section 315 communicates with the first pipe section 313. The dosing pipe 700 introduces the detergent output from the dosing port 830 into the third pipe section 315 through the water inlet 312. The third pipe section 315 then introduces the detergent into the first pipe section 313, and then through the first pipe section 313 and the second pipe section 314, the detergent is introduced into the water spraying channel 321 of the spray head 320. During the process of spraying the detergent towards the inlet 221 of the water inlet chamber 220 in the water spraying channel 321, the communication between the inlet 221 of the water inlet chamber 220 and the dosing port 830 is realized, achieving the purpose of directly delivering the detergent into the inner cylinder 200. This process of delivering the detergent will not bring dirt, bacteria, etc. between the inner cylinder 200 and the outer tub 100 into the inner cylinder 200. While ensuring that the detergent entering the inner cylinder 200 is free of dirt and bacteria, it also improves the utilization rate of the detergent and reduces the use cost of the detergent.

[0122] Optionally, as Figure 10 shown, in a plane perpendicular to the rotation axis of the inner cylinder 200, the projections of the second pipe section 314 and the third pipe section 315 in the plane both extend along the radial direction of the outer tub 100. The radially extending second pipe section 314 and third pipe section 315 are beneficial to the flow of the detergent on the one hand, improving the delivery efficiency of the detergent; on the other hand, to adapt to the positions between the inlet 221 of the water inlet chamber 220 and the dosing pipe 700, while reducing the volume of the water spraying member 300, it can also ensure that the water spraying member 300 accurately introduces the detergent into the water inlet chamber 220.

[0123] In some embodiments of the present invention, as Figure 7 and Figure 11 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 inclined downward, which is beneficial to the flow of water. Such a setting can also increase the coverage area of the water entering the water inlet chamber 220 on the water inlet chamber 220 and ensure that the water can be evenly sprayed into the water inlet chamber 220.

[0124] In some embodiments of the present invention, the water inlet chamber 220 extends circumferentially along the rotation axis of the inner cylinder 200, and the inlet 221 of the water inlet chamber 220 forms a circular ring, and the center of the circular ring is located on the rotation axis of the inner cylinder 200.

[0125] As the inner drum 200 rotates relative to the outer tub 100, it will drive the water inlet chamber 220 to rotate synchronously. Since the water spraying member 300 is fixedly connected to the outer tub 100, by forming the inlet 221 of the water inlet chamber 220 into an annular shape, it can be ensured that the water inlet chamber 220 will not be blocked by the water spraying member 300 during rotation, that is, it is ensured that the water inlet chamber 220 can rotate normally. And the above setting can also ensure that during the rotation of the water inlet chamber 220, the water spraying member 300 can always spray water towards the water inlet chamber 220 through the inlet 221, ensuring that the laundry treatment device 1000 can work properly.

[0126] In some specific embodiments, the water inlet chamber 220 forms an annular chamber, and the inlet 221 of the water inlet chamber 220 is arranged close to the inner wall of the inner circle of the water inlet chamber 220. In a plane perpendicular to the rotation axis of the inner drum 200, the projection of the water spraying channel 321 in the plane is tangent to the projection of the inner wall of the inner circle of the water inlet chamber 220 in the plane. This can further ensure that the water spraying channel 321 smoothly sprays water into the water inlet chamber 220, and while increasing the spraying distance, it can also ensure that the water can be evenly sprayed into the water inlet chamber 220.

[0127] In some embodiments of the present invention, as Figure 4 and Figure 9 shown, the inner drum 200 includes a drum body 210 and a bracket 230, and the drum body 210 defines a laundry treatment chamber 211. The laundry to be cleaned is placed in the laundry treatment chamber 211 to facilitate subsequent treatment of the laundry.

[0128] In some examples, as Figure 4 and Figure 9 shown, the drum body 210 is installed on the bracket 230, and the drum body 210 is rotatably arranged in the outer tub 100 through the bracket 230.

[0129] Here, the bracket 230 functions to connect the drum body 210 and the outer tub 100, so that the drum body 210 can be arranged in the outer tub 100, and the bracket 230 can also function to support the drum body 210 to increase the installation stability of the drum body 210.

[0130] Optionally, the water inlet chamber 220 is formed on the bracket 230, which is convenient for forming without damaging the structure of the drum body 210. And when the drum body 210 rotates relative to the outer tub 100, it can be ensured that the water inlet chamber 220 rotates synchronously with the drum body 210, so as to convey the water in the water inlet chamber 220 into the laundry treatment chamber 211 in the drum 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.

[0131] According to some embodiments of the present invention, the laundry treatment apparatus 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 bracket 230, and the bracket 230 is rotatably disposed on the outer tub 100 through the rotating shaft 240, so as to ensure that the tub body 210 mounted on the bracket 230 can rotate relative to the outer tub 100.

[0132] In some embodiments, the laundry treatment apparatus 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, so as to drive the bracket 230 to rotate relative to the outer tub 100, so as to rotatably dispose the tub body 210 in the outer tub 100.

[0133] Optionally, the bracket 230 is disposed on the tub body 210, and the central axis of the rotating shaft 240 connected to the bracket 230 coincides with the rotation axis of the tub body 210, ensuring that the tub body 210 will not be stuck or unable to rotate during the process of driving the tub body 210 to rotate by the bracket 230 through the rotating shaft 240, so as to ensure that the tub body 210 can rotate smoothly.

[0134] 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 are arranged at intervals along the axial direction of the outer tub 100. The rotating shaft 240 sequentially passes through the first bearing and the second bearing. The cooperation of the first bearing and the second bearing enables the rotating shaft 240 to stably rotate relative to the outer tub 100, so as to drive the tub body 210 to rotate relative to the outer tub 100.

[0135] Optionally, the bracket 230 includes a connecting ring in the middle and a plurality of connecting frames. The connecting ring is sleeved on the rotating shaft 240. The plurality of connecting frames are connected to the connecting ring and are arranged at intervals along the circumferential direction of the connecting ring. Each connecting frame extends radially outward along the connecting ring. The bracket 230 is connected to the tub body 210 through the plurality of connecting frames, so as to increase the contact area between the bracket 230 and the tub body 210, which can not only improve the connection stability between the bracket 230 and the tub body 210, but also help to ensure the force balance of the tub body 210, prevent the tub body 210 from being damaged due to excessive local force, and extend the service life of the tub body 210.

[0136] In some embodiments of the present invention, the inner tub 200 has a first water outlet, and the outlet 222 of the water inlet cavity 220 is communicated with the first water outlet. The outlet 222 of the water inlet cavity 220 is used to discharge the water in the water inlet cavity 220. Therefore, through the cooperation of the outlet 222 and the first water outlet, it is ensured that the water in the water inlet cavity 220 can smoothly enter the inner tub 200, so as to wet the clothes in the inner tub 200 and facilitate subsequent treatment of the clothes in the inner tub 200.

[0137] Optionally, a fixed and sealed connection is provided between the outlet 222 of the water inlet chamber 220 and the first water outlet, preventing water from leaking at the connection between the outlet 222 and the first water outlet. This not only improves the water inlet efficiency but also enhances the water utilization rate, thereby increasing the wetting efficiency of the clothes.

[0138] 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 the water, ensuring that the water flowing out of the outlet 222 of the water inlet chamber 220 can smoothly enter the inner drum 200 through the first water outlet.

[0139] In a specific example, the above-mentioned sealed connection can be achieved by setting sealing members, 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 members can prevent water leakage while also enhancing 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.

[0140] In some embodiments of the present invention, as Figure 4 and Figure 9 shown, the laundry treatment device 1000 further includes a plurality of lifting ribs 500. The plurality of lifting ribs 500 are provided inside the side wall of the inner drum 200, and the plurality of lifting ribs 500 are arranged at intervals along the circumferential direction of the inner drum 200.

[0141] During the process of the laundry treatment device 1000 treating clothes, as the inner drum 200 rotates, the plurality of lifting ribs 500 can drive the clothes to rotate simultaneously. On the one hand, the lifting ribs 500 can lift the height of the clothes, and the clothes fall back under the action of gravity, thereby realizing the up-and-down beating and flipping of the clothes to achieve the purpose of treating the clothes. On the other hand, the plurality of lifting ribs 500 can increase the contact area between the clothes and the inner drum 200, enabling the clothes close to the lifting ribs 500 to rub against the lifting ribs 500 to generate a kneading effect, thereby improving the clothes treatment ability of the inner drum 200 and enhancing the user experience.

[0142] In some examples, as Figure 6 shown, the inside of the lifting rib 500 is hollow, and the plurality of outlets 222 of the water inlet chamber 220 are in one-to-one correspondence and communication with the hollow parts of the plurality of lifting ribs 500. The outlet 222 is used to connect the inside of the lifting rib 500 with the water inlet chamber 220, ensuring that the water entering the water inlet chamber 220 can smoothly enter the inside of the lifting rib 500 through the outlet 222, thereby facilitating the subsequent input of water into the inner drum 200 to achieve the purpose of treating the clothes.

[0143] Optionally, a second water outlet is defined between the lifting rib 500 and the inner cylinder 200, and the second water outlet communicates with the hollow portion of the lifting rib 500. In this way, the water entering the hollow portion of the lifting rib 500 through the outlet 222 can flow into the interior 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 inside the inner cylinder 200.

[0144] In some examples, a part of the structure of the lifting rib 500 can be spaced apart from the inner cylinder 200 to form a second water outlet, facilitating the connection between the hollow portion of the lifting rib 500 and the inner cavity of the inner cylinder 200.

[0145] 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 procedure 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.

[0146] Optionally, the lifting rib 500 itself defines a second water outlet communicating with the hollow portion of the lifting rib 500. The interior of the lifting rib 500 communicates with the inner cavity of the inner cylinder 200 through the second water outlet on its own structure. Such a setting can also achieve the purpose of guiding the water inside the lifting rib 500 into the inner cylinder 200 to achieve water inlet.

[0147] It should be noted that by defining a 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 portion of the lifting rib 500 between the lifting rib 500 and the inner cylinder 200, so that 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 clothes treatment.

[0148] It can be seen from this that the technical solution of the present application is applicable to the clothes treatment device 1000 with a perforated inner cylinder (the inner cylinder 200 has a first water outlet), and is also applicable to the clothes 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, a second water outlet communicating with the hollow portion of the lifting rib 500 is defined between the lifting rib 500 and the inner cylinder 200, or the lifting rib 500 itself defines a second water outlet communicating with the hollow portion of the lifting rib 500), with little limitation.

[0149] Of course, in some other examples, a 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 second water outlets. Multiple second water outlets convey water towards the inner cylinder 100 at the same time, which can also improve the conveying efficiency and further improve the clothes wetting efficiency.

[0150] Such asFigure 6 As 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 circumferentially along 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, and improving the position stability of the lifting rib 500.

[0151] Optionally, as Figure 6 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 disposed opposite to the outlet 222. In this way, the water in the water inlet cavity 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 into the inner cylinder 200 to wet the clothes in the inner cylinder 200.

[0152] Optionally, a sealing ring 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.

[0153] In summary, for the laundry treatment device 1000 of the present application, when water needs to be conveyed into the laundry treatment cavity 211, first, the detergent is placed in the detergent accommodating cavity of the detergent placement box 850, and then the dosing pump 840 and the water inlet valve 900 are started. The dosing pump 840 is used to convey the detergent in the detergent accommodating cavity to the detergent dosing cavity 811. The water inlet valve 900 and the water inlet pipe 600 cooperate to convey the clear water from an external water source to the detergent dosing cavity 811. After the clear water enters the detergent dosing cavity 811, it dissolves the detergent in the detergent dosing cavity 811. As the clear water in the detergent dosing cavity 811 continuously enters, the water in the detergent dosing cavity 811 flows through the dosing port 830 into the dosing pipe 700 under the action of pressure, and is conveyed to the second water inlet 110 or the water inlet 312 through the dosing pipe 700. The water flowing into the second water inlet 110 or the water inlet 312 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 cavity 220 through the water spraying channel 321 to spray the water into the water inlet cavity 220.

[0154] In some examples, if a first water outlet is formed on the inner cylinder 200, the water sprayed into the water inlet cavity 220 can directly flow into the interior of the inner cylinder 200 through the outlet 222 and the first water outlet, achieving the purpose of delivering water to the inner cylinder 200; in other examples, if a lifting rib 500 is formed on the inner cylinder 200, the water sprayed into the water inlet cavity 220 can flow into the interior of the lifting rib 500 through the outlet 222 and the water passing opening 511. Subsequently, the water located inside the lifting rib 500 then flows into the interior of the inner cylinder 200 through the second water outlet, achieving the purpose of delivering water to the inner cylinder 200.

[0155] It can be seen from this that during the process of delivering the detergent by the laundry treatment device 1000 of the present application, the detergent is directly sprayed into the water inlet cavity 220 through the water spraying member 300, and then enters the laundry treatment cavity 211 through the water inlet cavity 220, avoiding the detergent flowing through the outer tub 100 first and then flowing into the inner cylinder 200. This not only shortens the flow path of the detergent, improves the delivery efficiency, but also can prevent the detergent entering the inner cylinder 200 from being contaminated with dirt and bacteria in the outer tub 100, enhancing the user experience.

[0156] A specific embodiment of the laundry treatment device 1000 of the present invention will be described below in conjunction with the accompanying drawings. Here, the laundry treatment device 1000 can be a drum washing machine or a drum washing and drying integrated machine.

[0157] As Figures 1 - 10 shown, the laundry treatment device 1000 includes: an outer tub 100, an inner cylinder 200, a water spraying member 300, a water passing channel 400, a lifting rib 500, a water inlet pipe 600, a dosing pipe 700, a detergent dosing assembly 800, and a water inlet valve 900.

[0158] The inner cylinder 200 includes a cylinder body 210 and a bracket 230. The cylinder body 210 defines a laundry treatment cavity 211. The cylinder body 210 is installed on the bracket 230. The cylinder body 210 is rotatably disposed in the outer tub 100 through the bracket 230. A water inlet cavity 220 is formed on the bracket 230 and is communicated with the laundry treatment cavity 211.

[0159] The detergent dispensing assembly 800 and the water inlet valve 900 are both arranged above the outer tub 100. The detergent dispensing assembly 800 includes a detergent placement box 850, a detergent dissolution box 810, and a dispensing pump 840. The detergent placement box 850 has a detergent accommodation cavity. The dispensing pump 840 and the detergent dissolution box 810 are both arranged behind the detergent placement box 850, and the detergent dissolution box 810 is arranged above the dispensing pump 840. The detergent dissolution box 810 defines a detergent dispensing cavity 811. The rear wall of the detergent placement box 850 is provided with a liquid outlet. The bottom wall of the detergent dissolution box 810 is provided with a liquid inlet 812. The dispensing pump 840 is used to transport the detergent flowing out from the liquid outlet to the liquid inlet 812, so as to transport the detergent in the detergent accommodation cavity to the detergent dispensing cavity 811.

[0160] A first water inlet 820 and a dispensing port 830 are formed on the detergent dispensing cavity 811. One end of the water inlet valve 900 is connected to an external water source, and the other end of the water inlet valve 900 is connected to the first water inlet 820 through a water inlet pipe 600.

[0161] The water spraying member 300 is arranged on the bottom wall of the outer tub 100. A water passing channel 400 is defined between the water spraying member 300 and the outer tub 100. The water passing channel 400 communicates with the water spraying channel 321 and the dispensing port 830. The dispensing port 830 is communicated with the water passing channel 400 through a dispensing pipe 700. The wall surface of the detergent dispensing cavity 811 forms a closed surface except for the positions of the first water inlet 820 and the dispensing port 830. In this way, the clear water entering the detergent dispensing cavity 811 through the water inlet valve 900 and the water inlet pipe 600 can be discharged from the dispensing port 830 into the water spraying channel 321 after dissolving the detergent, and the water spraying channel 321 then sprays the water towards the inlet 221 of the water inlet cavity 220.

[0162] 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 communicating with the hollow part of the lifting rib 500. A second water outlet communicating with the hollow part of the lifting rib 500 is defined between the lifting rib 500 and the inner tub 200. The hollow part of the lifting rib 500 is communicated 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 into the laundry treatment cavity 211 to wet the clothes in the laundry treatment cavity 211.
